     We determined the optimal storage temperature of

    shima
    -rakkyo, which is the rakkyo (Allium chinense) blanched. We found that the freezing point of
    shima
    -rakkyo was -1.8℃ and the respiration rate increased at 10℃. It was inferred that the suitable storage temperature for
    shima
    -rakkyo is in the range of -1.8℃ up to 10℃. We stored
    shima
    -rakkyo at 0, 2, and 5℃ for 6 months and investigated shoot elongation, percentage of rooted bulbs, taste, sugar content and pyruvic acid content, every two months. The shoot elongation and rooting of
    shima
    -rakkyo were inhibited as the temperature decreased. The taste of
    shima
    -rakkyo also tended to be better with the decrease in temperature. When stored at 0℃ for 6 months, shoot and root elongation was suppressed and the taste was preserved. We therefore concluded that the optimal storage temperature for
    shima
    -rakkyo is 0℃.

    This article is concerned with the nature of musical change in the folk songs (
    shima
    -uta
    ) of Amami Oshima, and in particular with qualitative change in methods of transmission of these songs. The research was conducted during a period of residence on the island.
    The island of Amami Oshima is located in the subtropical belt at an almost equidistant position between Kagoshima and the main island of Okinawa. The island is about 100 kilometres in length and has a population of approximately 85, 000. Administratively, it belongs to Oshima-gun in Kagoshima Prefecture.
    Shima
    -uta
    have been handed down in the manner of an exchange of song between men and women. They are performed to the accompaniment of the shamisen on occasions considered as appropriate by the village (
    shima
    ) community for such performances.
    Shima
    -uta
    are distinguished by melodies which differ from one
    shima
    to another, the
    shima
    being the group within which transmission occurs. The rapid changes which have occurred in village society over recent years have resulted in the collapse of the
    shima
    communities and the encroachment of urban ways of living. A byproduct of this development is that
    shima
    -uta
    are now generally learnt and passed on through the mediums of records, folk song competitions, and formal tuition.
    The districts in which folk song transmission occurs throughout the island may be classified roughly into the three following types:
    1) Districts where there still exist transmission groups with the same structure as the traditional communities, and where transmission continues to centre on traditional methods of learning.
    2) Districts where there is more scope for song performance than those described in the preceding paragraph and where modern methods of tuition are also practised. (In such districts both traditional and modern methods of learning are practised, centring on groups of music-loving friends rather than on traditional groups.)
    3) Naze, the main city on the island, where modern methods of study are practised on the foundations provided by the musical culture of the adjacent parts of the island.
    I made a comparison of districts 1) and 3), that is the city of Naze and the traditional
    shima
    -uta
    community of Sani, since these districts are representative of the centre and the periphery of
    shima
    -uta
    culture on Amami Oshima.
    People in the
    shima
    -uta
    community of Sani believe that the
    shima
    -uta
    genre is music symbolic of their community. The musical diversity within Sani is unified under a communal awareness that
    shima
    -uta
    (“community songs”) are the songs of this particular community. The music is constantly undergoing change as part of the intimate relation-ships between the individual and the group.
    In the main city of Naze, songs are learnt by individuals who freely select and learn the melody of a song as performed by their favourite singer (utasha); individuals may also introduce their own refinements into a melody. Here, there are no transmission groups directly to fetter the singing style of an individual. The musical diversity present in Naze leads to an attitude presupposing that
    shima
    -uta
    are the songs of Amami Oshima as a whole rather than of any particular community on the island.
    The term
    shima
    -uta
    thus assumes a subtly different meaning for individ uals in Naze and Sani, despite the fact that both districts belong to the same
    shima
    -uta
    culture of Amami Oshima.
    Comparison of these two diametrically opposed districts in connection with transmission makes it possible to surmise the diachronic changes which have occurred from the era when the traditional
    shima
    community was still alive down to the present. The world of the
    shima
    -uta
    in Amami was previously one which centred on one's own
    shima
    and in which the existence of

    This paper analyzes the local performing arts inheritance activities of schools in Amami Oshima island, and clarifies regional differences in the roles of schools. The relationship between the local community (
    shima
    ) and the school is considered, and the transformation of performing arts caused by school participation is discussed. Traditionally, the
    shima
    has been the space for local arts inheritance. Since arts inheritance activities have started in schools, they have been added as a new space for arts inheritance. The styles of the arts inheritance activities differ according to the geographical environment where the school is located. Schools located in urban areas have a tenuous relationship with the
    shima
    , and construct self-contained activities based on the logic of the school. In communities where enough manpower for arts inheritance activities, schools merely have the role of providing a place for the activities, and support the activities from the sidelines. On the other hand, communities located in non-urban areas where aging and depopulation have advanced have strong ties with the schools, and smooth cooperation can be seen. On the Amami Oshima island, the typical inheritance activity comprises dividing roles and cooperation between the
    shima
    and the school. The authentic arts are inherited by the
    shima
    , and the creative performance is mainly carried out at school. The most distinct characteristic of the inheritance activities is that a mutually complementary relationship exists between the
    shima
    and the schools in non-urban areas. It is unavoidable that native folk songs are transformed into educational materials. The identity of the songs that were created by the
    shima
    is threatened to be lost, because they are reformed as educational materials. On the other hand, schools played a role of creating new performing arts based on the community arts. The new arts created in schools are presented at administration sponsored events. They are distributed to both inside and outside of the
    shima
    . Initiatives in schools have the potential to go beyond the mere inheritance of the performing arts, and to sublimate to a new “performing arts of Amami Oshima,” or the
    shima
    arts. Inheritance activities of schools involve seniority order logic. This seniority order is remarkable in the local community of
    shima
    of Amami Oshima. The school adopts the same logic of seniority order into the school activities, which guarantees the continuation of inheritance activities in schools. The inheritance activities in schools is formed by a fusion of two logics: the logic of the
    shima
    being seniority, and the logic of schools being education. Schools have two leaders, namely teachers and inhabitants. They are based on different logics, and engaged in different inheritance activities. Furthermore, in small schools in non-urban areas where the school district and the region of the
    shima
    overlap, the logic of the
    shima
    and the logic of the school are integrated, and the inheritance activities of the schools exist concurrently. In addition, the school is starting to play a new role as a place for creating the arts of Amami Oshima.

    volcanic rocks in the the Hime-
    shima
    Island, southwest Japan are composed of five bodies: Daruma-yama lava (garnet-bearing biotite-hornblende dacite), Shiro-yama lava (garnet-bearing rhyolite), Yahazu-dake lava (biotite-bearing hornblende dacite-rhyolite), Morose lava (biotite-bearing hornblende dacite) and Hashiraga-dake lava (garnet-bearing biotite-hornblende rhyolite).
    These rocks can be divided into two types: garnet-bearing and garnet-free types. The lavas of garnet-bearing type are subdivided into hornblende-bearing and hornblende-free subtypes. The lavas of garnet-free type are distributed in cenrtal parts of the Hime-
    shima
    Island, while those of garnet-bearing type are in the eastern and western ends of the Hime-
    shima
    Island.
    Hime-
    shima
    volcanic rocks range in composition from dacite (morose lava; SiO2=68.81%) to rhyolite (Shiro-yama lava; SiO2=74.88%). The lavas of garnet bearing type tend to be more felsic than those of garnet free type. The Hime-
    shima
    volcanic rocks may represent a later stage of magmatic differentiation, but it seems difficult to decide whether these volcanic rocks are derived from an original basaltic magma or they are remelting products of deeper part of the crust.

    Seasonal growth and population structure of hijiki (Sargassum fusiforme) was surveyed at two rocky reefs contiguous to each other, i.e.Saba-
    Shima
    and Sen-emon-Dashi, in Hime, Kushimoto-cho, Wakayama Prefecture. In spring, the harvest season of hijiki for fisheries, thalli in Saba-
    Shima
    were significantly larger than thalli in Sen-emon-Dashi. A permanent quadrat was set at each reef and the growth pattern of hijiki in the quadrat was monitored monthly from June 2012 to April 2013. In the population at Saba-
    Shima
    , main branches had already been developed in many hijiki thalli in June, and their rapid elongation began in November. On the contrary, the population at Sen-emon-Dashi was dominated by rosette-type thalli with cauline leaves extended radiately and no main branches developed during summer and autumn. Frequency of thalli with developed main branches increased and their rapid elongation began in January at Sen-emon-Dashi. Even after the onset of rapid branch elongation, daily elongation rate was far larger in the population at Saba-
    Shima
    than in the population at Sen-emon-Dashi. Difference in seasonal growth and developmental pattern was attributable to the difference in spring thallus size of hijiki between the two reefs.

    Ticks often carry infectious pathogens, and ticks infected with pathogens can be transmitted to seabirds. In May 1999, a project team member contracted a fever after being bitten by a tick during a field survey of albatrosses on Tori-
    shima
    . The researcher was bitten while in the main part of the Black-footed Albatross D. nigripes colony. Serodiagnosis indicated that the patient had been affected with borreliosis. The tick species involved was collected on Tori-
    shima
    and identified (based on its morphology) as the soft tick Carios (Ornithodoros) capensis.
    A survey was carried out on Tori-
    shima
    in March and May 2000 in order to isolate the spirochete from the soft tick C. (O.) capensis, the host albatross D. nigripes and the Roof Rat Rattus rattus. We were unable to isolate Borrelia from either C. (O.) capensis, from blood or from the skin of the underside of the feet of D. nigripes, or from the ears or bladder of R. rattus. Nevertheless, ticks can be a negative factor affecting seabird reproduction. We report on the ecological status of C. (O.) capensis on Tori-
    shima
    , describe the relationship between this tick species and the various host animals on the island, and propose that surveys for ticks in seabird breeding colonies are very importance.

    Miocene volcanic rocks were discovered in the Geiyo Islands, western Setouchi region of southwest Japan. These occur as dikes or volcanic necks with marginal pyroclastic rocks. The volcanic rocks are composed of high-alkali tholeiitic olivine basalt, olivine andesite and bronzite andesite, in which the olivine andesite from Oge-
    shima
    chemically corresponds to high magnesian andesite.
    Whole rock K-Ar age determinations were carried out on olivine basalts, olivine andesites and bronzite andesites. An olivine andesite from Osakishimo-
    shima
    and two bronzite andesites from Okamura-
    shima
    yielded late Miocene ages of 8.2±0.7 Ma, 7.8±0.4 Ma and 8.0±0.4 Ma, respectively. It follows that subalkaline volcanism distinctively occurred at late Miocene age in the western Setouchi region. Accordingly, we give a name of “Geiyo volcanic rocks” to these volcanic rocks, which include late Miocene high-alkali tholeiitic olivine basalt reported from the adjacent area.
    On the other hand, olivine basalts from Okubi-
    shima
    and Ko-oge-
    shima
    give middle Miocene ages of 12.8±0.6 Ma and 15.4±0.8 Ma, respectively. In addition, an olivine andesite from Oge-
    shima
    has been dated as 17.4±0.9 Ma, indicating early Miocene age. On the basis of the radiometric ages, petrography and whole rock chemistry, these volcanic rocks are considered to be a member of the Setouchi volcanic rocks.

    We estimated the breeding origins of 40 Ryukyu Robins Erithacus komadori captured outside their known breeding range on the Sakishima Islands, the southern part of Okinawa-jima, and Kyushu based on 1226 base pairs of the mtDNA control region sequence. This mtDNA region is known to be an ideal genetic marker for estimating the breeding origin of migrating individuals since four genetically distinct groups of breeding populations have previously been identified: three groups of the northern subspecies (E. komadori komadori; Tokara, Oh-
    shima
    , and Tokuno-
    shima
    groups) and a single group of the southern subspecies (E. komadori namiyei; Okinawa-jima), each of which consists of mostly endemic haplotypes. Among the migrating individuals, Tokara haplotypes dominated (35 individuals). However, three individuals sampled in the Sakishima Islands had an Oh-
    shima
    haplotype and two other individuals had Tokuno-
    shima
    haplotypes. The migrating individuals from these two populations were not restricted to certain sex or age classes. The populations in Oh-
    shima
    and Tokuno-
    shima
    were found to be partially migratory and not completely sedentary, with some individuals migrating as far as the Sakishima Islands. Further studies are needed to clarify the relative frequency of migratory individuals in these populations. Additionally, individuals with Okinawa-jima haplotypes were not found outside its breeding range during the nonbreeding season, suggesting that individuals in this population are strictly sedentary.

    town is divided by 4 sections which were former villages before 1955. and is situated at the end of ITOSHIMA peninsula. It is far form the main rout but bus rout extend to each sections from adjoining town MAEBARA. Most of localities are classified into agricultural and fishing type. Shops sell the daily neccesities, for example, bread and cakes, provisions, row fiishes, liqor and tobaccos. The inhabitants depend them upon the shops at
    SHIMA
    town. The durable goods, for example, furnitures, meats, books and magazines, watches and glass, medecines, cloges, radio and TV sets, and clothes are few sold here. They depend them upon the shops at MAEBARA town. In conclusion, it is considered that

    In this study, based on the data from FIV screening surveys of captive cats conducted by the Kyushu Veterinary Union and collaborators as part of the infection control program for Tsushima leopard cats (Prionailurus bengalensis euptilurus), we elucidated the spatial distribution of FIV-positive individuals among leopard cats and domestic cats using a geographic information system. Data from FIV screening surveys carried out among 86 leopard cats (1996-2006) and 713 captive domestic cats (2001-2006) were used for analysis. The analysis results were then spatially layered with the population density of leopard cats and that of captive domestic cats estimated from the number of households and used for assessment of FIV infection risk in each area. The prevalence rates of FIV were 3% (3/86) in leopard cats in Kami-
    shima
    , 13.6% (38/280) in domestic cats in Kami-
    shima
    and 10.6% (46/433) in domestic cats in Shimo-

    . The distribution of FIV on Tsushima Island was not uniform; on Kami-

    Island, FIV-positive domestic cats were concentrated in particular areas. We also performed risk analysis based on the population density of leopard cats, the prevalence rate of FIV among domestic cats in each area and the estimated population density of captive domestic cats and identified high FIV infection risk areas. All FIV-positive leopard cats were found in the identified high FIV infection risk areas.

    Fragments of earthenwares of the Earliest Jomon age are found on a sea-cliff at Shimotakabora on the west coast of O-
    shima
    Island, Izu Islands (34°44.3′N., 139°21.6′E.). They are unearthed from the upper brown weathered ash of a unit layer constituting pyroclastic fall deposits exposed there. Associated with them, are found obsidian flakes, an angular block of biotite rhyolite pumice, several round pebbles of compact basalt, and a small amount of charred wood and bone fragments.
    All the earthenware fragments are identified to be of the Hirasaka type of the Earliest Jomon age whose type locality is in the Miura Peninsula, South Kanto. Two samples of the obsidian flakes have been determined by fission track method to have the same uranium content and age as obsidian exposed on Kozu-
    shima
    Island about 60km south-southwest of O-
    shima
    . The biotite rhyolite pumice block is, in petrographic characters, similar to the biotite rhyolite from any one of Nii-jima, Shikine-jima or Kozu-
    shima
    Islands, all of which lie to the south-southwest. These obsidian and rhyolite pumice were brought by the Earliest Jomon (Hirasaka) men to O-
    shima
    Island for making living tools.
    On the sea-cliffs at Onoue and Tatsunokuchi to the south of Shimotakabora, earthenware fragments of the Kayama, Kijima plus Sekiyama, Moroiso (?) and Odoriba types have been unearthed from the particular stratigraphic levels of superimposed pyroclastic deposits. The earthenware fragments of the Hirasaka type are found at the layer lying nine fall units below the level which contains the earthenware fragment of the Kayama type about seven thousand years old. As the time represented by a unit pyroclastic layer is thought to be a hundred and several tens of years, the earthenwares of the Hirasaka type may be brought to O-
    shima
    eight to nine thousands of years ago. This estimated age well coincides with that given so far to the type.

    The aim of this investigation was to study a manufacturing system by the method of a centrifugal casting technique for a ceramics/metal functionally gradient material (FGM). The centrifugal force enables the ceramics powder in a metal to create a gradient distribution. The mixture consisting of plaster and corundum was chosen as an experimental model. The mixed materials were cast into rings under the combined conditions of four different volume fractions and three different No. times of gravity. The corundum profile was measured and analysed by cubic order polynomial equation. A mathematical model based on the expression was proposed to consider the effects of the volume fraction of the powder and the centrifugal force on the distribution. The model can express the observed distribution fields in a unified manner. A manufacturing system using the model was discussed in terms of whether it satisfies the designed distribution of the powder.

    Synovial osteochondromatosis, a benign condition of unknown origin, is characterized by multiple cartilaginous and osteocartilaginous nodules arising from metaplasia of the synovial tissue. The most common sites are the knee, the elbow, and the hip joint; it rarely occurs in the ankle or foot. We report a rare case of synovial osteochondromatosis in the retrocalcaneal Bursa.
    A 31-year-old woman suffered from an insidious pain and swelling around the insertion of the right Achilles tendon for about two years. Gradually the hindfoot pain became severe, especially on weight bearing, and the swelling enlarged. Physical examination revealed a hard 1 cm mass with a smooth surface attached to the insertion of the Achilles tendon, There was marked tenderness over the mass, and the patient complained of pain of the hindfoot while she was walking. Routine radiographs of the right ankle were almost normal. A computed tomography scan revealed a f aintsof t tissue mass with a granular shadow at the anterolateral aspect of the Achilles tendon. A magnetic resonance image with T1-weighted sequences and T2-weighted sequences showed an image suggestive of multiple cartilaginous shadows with effusion in the retrocalcaneal Bursa. The mass was removed. There was an elastic, hard mass with a fibrous capsule situated at the anterolateral border of the right Achilles tendon, which was contiguous with the paratenon of the Achilles tendon. Several hard whitish fragments, like cartilaginous nodules, were connected by fibrous tissues. Histopathological examinations showed proliferative hyaline cartilages in the hypertrophied synovial bursa with fibrous degeneration. These findings were compatible with a diagnosis of synovial osteochondromatosis of the retrocalcaneal Bursa. Nine months after the operation, she was still free from symptoms. One should consider synovial osteochondromatosis of the retrocalcaneal Bursa as a differential diagnosis of hindfoot pain.

    In Japan there have been many utsushi-reijô (imitative pilgrimage courses) patterned after Shikoku-hachijûhakkasho-reijô (Shikoku's 88 pilgrimage sites) and they are called shin-shikoku (‘new shikoku’pilgrimage courses) or mini-shikoku (miniature shikoku pilgrimage courses). These shin-shikoku can be regarded as pilgrim courses in which the Honshikoku (Shikoku pilgrimage course) model spread to various parts of the country and were transformed under local conditions. Meanwhile shin-shikoku have been transformed historically since their establishment. In this paper the author focuses on the former regional transformation.
    The area of the case study is Shôdoshima-hachijûhakkasho-reijô (Shodoshima's 88 pilgrimage sites) on Shodoshima Island in Kagawa Prefecture. The procedure is first to compare
    Shima
    -shikoku
    (the Shodoshima course) with Hon-shikoku at the time of its establishment and find out what was imitated; next to determine how points differing from Hon-shikoku originated in
    Shima
    -shikoku
    . Results are as follows:
    1. Similarities between
    Shima
    -shikoku
    and Hon-shikoku are that fudasho (each pilgrim place) were placed at the periphery of the island so that pilgrims could go around it, and the direction of numbering from 1 to 88 was clockwise.
    2. Fudasho in
    Shima
    -shikoku
    included all the Shingon-shû (Shingon sect of Buddhism) temples in Shodoshima Island and all the highest-status shrines which later became gôsha (district shrines). The rests were selected from priests' meeting halls, oku-no-in (inner temples), wayside small temples, small temples at cemeteries, historic small temples, small temples at strange site features, and so on.
    3. Fudasho in
    Shima
    -shikoku
    were placed in every village in Shodoshima. The number 1 is supposed to have been assigned to the nearest fudasho to Koyasan-Temple.
    Historical transformations include allocations of fudasho, changes of fudasho-numbers, rise and fall of bangai-fudasho (extra pilgrimage places) and so forth. Even during these transformations
    Shima
    -shikoku
    have tended to copy Hon-shikoku in that the former have adopted the sekisho (spritual barrier to sinners) found in the latter at an earler time.
