ヘモシアニンによるV. B₂減少作用を解明するため, V. B₂に及ぼすヘモシアニンの濃度, 時間およびヘモグロビンの影響について検討し次の結果が得られた.
1) ヘモシアニンはグロブリン様たん白質とCu⁺の結合したものであるが, グロブリンではV. B₂は減少しない.
2) ヘモグロビンでもV. B₂は著しい減少傾向を示し, その構成成分であるグロビンではなんら変化しないが, ヘムによりV. B₂は減少する.
3) 一酸化炭素バブリング後のヘモグロビン, ヘモシアニン, 墨にはV. B₂減少作用が見られない.
4) V. B₂に酸素をバブリングすると, V. B₂は減少する.

前報に引き続き, 同様の7種類の一時性, 3種類の耐洗たく性防炎加工布を用いて, とくに安全性の面から加工条件および防炎性能と燃焼時における煙およびCO, CO₂の発生量との関係について未加工布との比較検討を行った.
その結果を要約すると次のようになる.
1) 煙濃度, CO, CO₂いずれの濃度も未加工布と比較すると付着率8～10%, LOI28～30のところにおいて急激な減少をみせ, 前報で示した防炎性能を備えた条件においてcriticalな発生量の減少を示した.
2) 耐洗たく性加工布については, ノンソーピングでは発煙量が多く, ソーピングと洗たくにより減少したのに対し, CO, CO₂はノンソーピングでは発生量が少なく, ソーピングにより難燃性の低下に伴って発生量が増大したが, 洗たくによる加工剤脱離により減少した.
3) 難燃性の十分な加工布はCO, CO₂の検出が5分以内に終止し人体への影響の面でも好ましい結果がみられた.
4) ホウ酸・ホウ砂は最も少ない付着量で最も防炎効果が大きく, その上人体への影響も少ないことが示された.この加工剤は一般消費者が日常手軽に購入できるというメリットとともに, 一時性であっても洗たく後糊つけ程度の簡単な操作で十分効果を発揮するところに注目したいと考える.化学的, 工業的レベルにおいて研究開発されることのみに頼り, 安全性の面で保証不十分であったり, コスト面での高騰をまぬがれない市販品に目を向ける前に, 消費者自身手近に安価で入手でき, まったく無害である薬剤を用いて日常生活に取り入れる試みをすることこそ防炎加工製品の一般化の第一歩として重要な役割を占めるものであり, このような方向に向かって研究することも家政学の一つの役割であろうと考える.

A study on sliding phenomenon of a mat on the other carpet was studied. The mat moves when a man walks over the mat placed on the carpet. This slide phenomenon of the mat has relation with physical properties such as kind of materials, frictional coefficient, length of pile and inclination of the pile itself.
The 12 different types of the carpets which have different properties were used as samples for the experiment. In this experiment the slide lengths of the mat putting on the carpet were measured.
The results of the experiment are as follows :
(1) The smaller the carpet density of the pile, slide length is larger.
(2) The smaller frictional coefficient and the longer the pile length, the mat is more slide.
(3) The mat on the carpet which has cutted pile is less slide.
(4) The larger the pile density, the mat on the carpet is less slide.
(5) The mat on the carpet which has looped pile is more slide.

In order to appropriately design the swing angles of ragran sleeve, a sensory test was carried out on the visual fitness for the test wearers evaluated by a group of panel members.
The results have showed that the degree of the agreement between the swing angle to the vertical line of the upper arms of the test wearers and those of the weared ragran sleeves well corresponds the visual fitness thus evaluated.
Especially, as far as the test wearers whose forms of the upper arms fairly deviate from standard ones are concerned, a more remarkable correspondence is established.
In conclusion, for suited design of ragran sleeves, it should be necessary to adjust the difference between front sleeve angle and back sleeve angle to the angle of the upper arm swing of the wearers.

In general, principal component analysis (PCA) is considered an effective procedure to reduce complex information composed of numerous characters to a few incorrelated synthetic groups. The method of PCA on somatic measurements is, however, not established yet. In this report, height and weight, the most commonly used items in somatometry, were examined to clarify the effect of selection of measurement items on PCA.
Materials were 500 boys of age 7, measured in 1966-1967 for their height, weight, posterior arm length, iliospinal height, tibial height, foot length, waist length, posterior shoulder length, neck base girth, bust girth, waist girth, hip girth, scapular and triceps skinfold thickness. PCA was applied to correlation matrices based on all of these 14 items (complete case), on 13 items excluding body weight, and on 12 items excluding height and weight. The conclusions are :
1) Coefficients of determination in each component following PC2 were larger in weight excluding case than in complete case. Eigenvectors and factor loadings in the first three components were also larger in weight excluding case.
2) Excluding both height and weight, eigenvalues became lower while coefficients of determination in PC1 and PC2 became heigher than those in case excluding weight solely. For eigenvectors and factor loadings, all variables in each PC were more loaded in the same way. Therefore, the interpretation of each component became much more easy.
3) From these results, we conclude that height and weight are preferable to be excluded from the item selection in PCA. For the reason that both of them represent total body mass measurement having common information with other variables, they reduce the effect of interrelationship between others.

As to dairy farming, Hyogo stands at the top of the prefectures in Western Japan and the fifth in all Japan. The life-pattern of dairy farmers' wives is different from that of ordinary housewives and characterizes the dairy farm household. However, there are many problems arising from this, and we made a fact-finding survey so as to search for the causes of the difficulties dairy farms have in common, hoping to get a clue to the problems.
The survey showed that there are problems in the routinized dairy life of the family members. The following suggestions are made to improve the situation toward attractive dairy farming business : decrease the working hours of the housewives, increase household care, promote healthy food and clothing, and finally, rationalize dairy farming. Also they are advised to learn agricultural book-keeping by utilizing their leisure time.
