     In today’s semiconductor industry, especially in the field of system LSI (Large-Scale Integration) devices, an international division of labor called vertical international specialization has developed. Due to this development, Taiwanese foundries like TSMC (Taiwan Semiconductor Manufacturing Company) have risen, their new business model promoting great leaps of amelioration. On the other hand, Japanese IDMs (Integrated Device Manufacturers) that have shifted their main production from DRAM (Dynamic Random Access Memory) to system LSI devices have been sluggish for a long time. TSMC, pushing a vertical specialization forward, strengthened their system coordination between plants and companies. They not only expanded online services, but attracted and retained customers such as fabless companies. On the other hand, it was possible that Japanese IDMs were tied down by the burden of their internal system coordination between not only the wafer fabrication and assembly system, but the cost accounting system as well. Japanese IDMs have been hindered by the many burdens and restrictions that occur from their system coordination problems in carrying out the system LSI businesses. This paper demonstrates that such problems contribute to the critical cause of their difficulties.

     One of the keys to improving labor productivity is to build organizational capability which will be achieved by highly utilizing both business administration and information technology (IT). Material requirements planning (MRP) is a powerful tool that implements both the theory and practical IT of production management and thus plays a central role along with a product lifecycle management (PLM) to create values in the manufacturing industry. A next step will be to develop MRP into "smart MRP" which is capable of flexibly update schedules in response to real-time situations in the production line.

     This study was conducted with a main objective: to suggest a capable of flexibly in MRP scheduling. After to systematically review how IT and capability maturity model integration (CMMI) can be utilized in building organizational capability. Specifically, taking the production of aircraft parts as an example to discuss how production scheduling can be made more flexible by cooperation MRP and business rule management system (BRMS) into smart MRP.

     Hakuba village in Nagano Prefecture was one of the venues of XVIII Olympic Winter Games in Nagano in 1998. The village has been filled with ski visitors for a long time, however, the decrease of tourists, especially ski visitors was remarkable since the beginning of the 1990’s. People and organizations with tourism industry in the village had repeatedly considered about the future way of the tourist destination after the Olympic Games. One of numerous countermeasures was to change the roles of the tourism organization and to strengthen the structure of it. The tourism organization acquired a corporate case in 2005, which was one of the solutions.

     This study tried to verify the financial soundness of the organization by corporate financial indicators, whether the organizational structure was strengthened on the financial side by incorporation.

     It was verified that the safety of the organization in finance was high because it had no fixed liability, and transaction profitability improved in 9th to 12th terms than in 2nd to 7th terms, but capital profitability declined.

     The 2016 Kumamoto Earthquake, hit southern part of Japan(Kumamoto) in April 2016, was the biggest earthquake than the one that struck japan for 10 years. Freeways, roads, and bridges were damaged, as a consequence there ware many problems in physical distribution.

     In order to management physical distribution as normal as possible under the earthquake. Some management processes in physical distribution under the Kumamoto Earthquake must be discussed. I discussed some management processes for a track transport company.

     First of all, the sales had not decreased in comparison with average in the past. Second the sales per the traveling kilometers had decreased slightly in comparison with average in the past. Third, driver's working hours had not increased in comparison with average in the past. The case of them is that they returned without loading the returning baggage after they carried the outbound baggage. On the other hand, the sales had decreased by 40% at an automobile repair shop, because of damaged equipment in the office, afflicted employees, and stop of Land Transport Bureau.

     This paper introduces a case of management for physical distribution under the 2016 Kumamoto earthquake.

     Today, the long-term survival of a firm needs sustainable relations with a broad range of stakeholders. This is result of CSR construction since 1920’s. CSR becomes more importance with increasing of company’s scale and role in society. However, CSR has opposing views, positive view and negative view ([1] p.37), Former is based on assumption of companies that have multi-objectives and latter based on assumption of companies have single objective. These two competing views contrast each other and additionally, affected other two opposite theories, stakeholder theory and positive agency theory, have supported each theory since 1970-80’s. Since outbreak of this conflict, these two conflicts, that are conflict between positive view and negative view in CSR and conflict between stakeholder theory and positive theory, have long been entrenched. The purpose of this study clarifies conflictive point in adopting and practicing CSR by tracking process of conflict spreading. It also reveals that not only shareholder’s value and positive agency theory, CSR and stakeholder theory also have problems.

     For several years there have been cautions about a decline in physical fitness in Japan, but we have not returned to the highest level, which was seen in 1985. However, not all Japanese people need to have a high level of physical fitness. The authors have been proposing a level of physical fitness with optimal relevance to lifestyle behavioral patterns. Thus, company employees only need to achieve physical fitness suited to their company environment, and they do not need to raise their level of physical fitness. However, national defense personnel, because they have a great impact on the national benefit, need to have physical fitness greater than the average level of the population. However, even assuming that the physical fitness of national defense personnel exceeds the average level of the Japanese population it cannot be said that physical fitness of optimal relevance to the environment of national defense personnel is being achieved. In this study, we constructed a physical fitness evaluation chart for age-related changes in 2,148 South Korean marines and conducted a comparison with data on Maritime Self-Defense Force students. In this way, we examined the physical fitness of optimal relevance for Maritime Self-Defense Force students and investigated the productivity of future national defense education.

     Studies based to demonstrate delayed menarche have been undertaken with age at maximum peak velocity (MPV) of height as an indicator of maturity as a fundamentally important perspective. However, the proposed critical weight hypothesis and fat hypothesis are thought to have behind them a close relationship between menarche and body weight. In this study, given that there is thought to be a high correlation between age and MPV of body weight and age at menarche, we constructed a regression evaluation chart of age at menarche against age at MPV of weight. We then compared delayed menarche evaluated in this way with delayed menarche evaluations determined from age at MPV of height. By examining at the level of agreement, we investigated the validity of delayed menarche evaluation based on age at MPV of weight and the error when using age at MPV of weight, and performed a risk analysis of whether evaluations based on age at MPV of weight could be an indicator of maturity.

     Environmental factors related to dietary nutrition in Japan changed dramatically with the rapid economic growth that occurred over the nearly 20 years from 1955 to 1972. These changes in diet had a large influence on the bodies of Japanese. However, very few studies have directly examined high-level economic growth and changes in physical growth over time, and there are no studies on early childhood. In this study we identified the first largest peak velocity (FLPV) in the year after birth with physical growth records (height, weight, chest circumference, head circumference) in young children from 1960 to 2010, and applied wavelet interpolation to the changes over time in two sets of data: the physical growth records of young children and GDP for the same years. A cross-correlation function was applied to the relationship between the derived curves of changes over time in FLPV in the physical growth records of boys and girls, and a curve of the changes over time in GDP. The relationship between high economic growth and physical growth in early childhood was then explored.

     The back hip circle is a learning tool that is simple and provides a strong sense of achievement in elementary school physical education class. For children, it has value as a hurdle that must be overcome physically. This value shows the same kind of meaning as when Japanese people learn “radio exercises.” The back hip circle is also an important physical exercise task that Japanese children should attempt to achieve. It is a horizontal bar element in apparatus gymnastics, but today it is also a task for children nationwide. In this study, we will apply a wavelet interpolation model to the horizontal bar back hip circle success rate in preschool and schoolchildren, who were said in a previous study to provide a high return on investment for society. The progress curve for the success rate will be described, and the level of physical maturity in the success rate progress investigated from the behavior of that progress speed curve. We will then investigate the relationship between the level of physical maturity with the back hip circle and non-cognitive skills. In addition, judging from the Fujimmon growth curve, we will compare the 50 m dash progress curve and the back hip circle success rate progress curve and, since the back flip circle can provide information for judgments of motor sense and be a parameter for level of maturity, explore management that will raise the productivity of back flip circle teaching instruction.

     In this study, we first extracted cross-sectional growth data on height from the first year of elementary school to the final year of high school for the years from 1955 to 2015 in Fukushima Prefecture, based on body composition data for each prefecture published by the Ministry of Education, Culture, Sports, Science and Technology, in order to determine the status of physical growth during the years of high economic growth in Fukushima Prefecture following the Second World War. Cohorts for these temporal data were then established and reviewed, and a wavelet interpolation model was applied to these growth data in cohort fashion. The age at maximum peak velocity (MPV) of height was identified from the described velocity curve, and the temporal change trends were analyzed. Next, we applied the wavelet interpolation model to longitudinal growth data for height from the first year of elementary school until the final year of junior high school (grade 9) in regions where there was a confirmed effect from earthquake disasters, and identified the age at MPV of height for individual students. Evaluation criteria for level of physical maturity were created from the identified individual MPV age statistics, with the pre-earthquake evaluation criteria taken as the core of the physical catch-up model construction theory. Then, the basic theoretical background was explored to examine the question of whether physical catch-up occurred in a short period from the behavior of MPV age for height of the Great East Japan Earthquake that struck several years ago, and a risk analysis of biological parameters from earthquakes was conducted.

     In recent years the need for building physical strength and maintaining or enhancing health in all age groups, from children to adults, has been publicized. However, theories have not been constructed for the series of activities involving surveys, measurements and feedback on results in the actual places where health and physical strength are developed. The author, using a simple health creation feedback model (Tanaka et al., 2013) that applies the logistics theory that is at the core of the distribution system, implemented activities to develop physical strength in children with coordination between a research institution and local childcare centers. Based on those activities, this study conducted an examination from the perspective of improving the productivity of this system. Here we report a process analysis conducted in a series of activities related to the analysis of collected data and feedback on assessment and measurement results.

     We previously proposed a “simple health promotion feedback model” (Tanaka et al., 2013) that applies a logistics theory aimed at strategic rationalize of work content with a distribution system at its core. In this study, we attempted to verify the use of this feedback system from implementation of fitness promotion activities that were undertaken collaboratively by a research institution and community day care centers. In this study, we attempted specifically to validate the process sequence of the public relations system and measurement system in this feedback model. This is the first stage in a series of studies to establish the validity of this system.

     The classifications in the process analysis in this study were initially divided into “movement,” “communication,” “meetings,” “documents,” “preparations,” and “measurements.” From the results of process sequence validation using these classifications, the public relations system was shown to consist of 9 processes based on the activities in “within research institutions,” “by research organizations and local governments,” and “by local governments and day care centers.” The measurement system processes were divided into 3 steps based on the activities “within research institutions,” “by research organizations and local governments,” “by research organizations and day care centers,” and “by local governments and day care centers.” The first stage was shown to consist of 7 processes, the second stage of 9 processes, and the third stage of 10 processes. In the future, it will be necessary to observe and survey the time, movement distance, and other factors in this process and to analyze the decrease in loss need.
