An experiment was performed on the model system to investigate the process of oxidation of sebum adhered to clothes. Lard, which consists of similar fatty acid composition to sebum and does not contain antioxidant, was used as a model substance. Test-fabrics which were soiled with lard were hung in an incubator controlled at 50°C, 40°C and 30°C for 1-60 days. The degree of oxidation of the lard extracted from the fabrics was followed through the peroxide value, carbonyl value, concentration of conjugated diene hydroperoxide, and fatty acid composition.The results were summarized as follows;1) No appreciable difference among the degrees of oxidation of lard adhered to cotton, wool, acrylic, and polyester fabrics was observed. From this fact, it could be considered that there was little effect in each fiber to the oxidation of lard.2) It was recognized that the rate of autoxidation of lard on fabrics was very rapid.3) Linolic and linolenic acids were more rapidly decomposed than oleic acid.4) The autoxidation rate of lard on fabrics increased by twice, when aging temperature rose by 10°C

Recent years have seen the emergence and continued evolution of anunprecedented landscape of digital media products and platforms, mobiledevices, and distribution and consumption patterns. Triggered and acceleratedby digital innovation, these changes have given rise to new challenges for legacy media organizations, such as newspaper publishers. A transformation of thenewsroom has been underway in major publishers around the world. The AsahiShimbun, the second largest national daily in Japan, is no exception. This paperis in the process of transforming itself into an integrated news organization( i.e.,one that publishes in both digital and print formats). Reporters and editors areexpected to adapt their mindset and workflow and adopt new skills and roles inline with audience-first journalism. Given this, we have set three goals: ⑴ toserve targeted audiences with targeted content; ⑵ to publish on the platformsused by the target audience; and ⑶ to produce and publish continuously tomeet audience needs. This requires a deeper, broader understanding of the targetaudience, so the paper has developed Hotaru, a new editorial analytics dashboardfor the newsroom in 2016. An abbreviation of “in-HOuse Tool for Analyzingand Reporting Users’ Activities,” Hotaru provides reporters and editorswith access to a rich source of real-time data, thereby helping them to developa better understanding of the impact of stories and the importance of audienceengagement. This new habit of looking at data is clearly helping to encourageeditorial experiments in the newsroom. For instance, if journalists want toreach out to mothers for stories on parenting, they can strategically use LINE,a messaging app that is popular among mothers. In this case, such stories areshared and spread effectively through the mothers’ networks. In another successfulcase, a reporter can, based on single coverage, file two types of storiesto meet the needs of two different target audience groups.

教科教育における教科間の内容のかかわり合いに関する研究の一環として,女子中等教育における理科化学と家庭科の内容が,相互にどうかかわり合っているかを,教授要目および指導要領の変遷を中心に,歴史的に追跡した。20世紀初頭,高等女学校教授要目が制定された時には,生活に関連した物質は理科化学で扱われており,家事科は専ら技術教育であった。第2次大戦中の教授要目の改訂は,家政科を中心としたコア・カリキュラム的性格をもっており,従って,理科化学分野も生活に関係深い事項や物質が重点的に扱われており,両教科の関係は最も密接であった。そして,戦後の生活理科の時代には,内容としての生活の科学が方法としての問題解決学習と結びついて,化学という学問のもつ系統性を十分に教育にとり込めなかったため,その反動として,その後の指導要領の改訂によって,化学は身近かな生活から離れてゆき,一方,家庭科は技術教育中心の状態からの脱皮が不十分で,現在は,両教科は著るしく離反している。しかし,現今の社会状勢からみて,これは早晩再考を迫られるであろう。
