"In this study, we explore the evolution of a corporate system by analyzing the case of production and employment structures in the Toyota Group. Our findings show that the production structure of the Toyota Group, which has been gradually affected by external, market, and institutional factors since the 1980s, transformed in 2009 from a domestic-oriented production structure to an overseas-oriented production structure. We also determined that since 2004, the domestic employment structure of the Toyota Motor Corporation has evolved to allow the flexible management of worker supply and demand through the hiring of nonregular workers, in response to the amendment to the Worker Dispatching Act. Consequently, the Toyota Group's production and employment structures have evolved to help secure channels that help the company flexibly adjust its output in response to abrupt economic fluctuations."

"Untuk meningkatkan obat tradisional menjadi sediaan obat fitofarmaka diperlukan penelitian mengenai kandungan kimia tumbuhan obat. Pada studi ini telah dilakukan isolasi dan identifikasi senyawa asam fenolat yang terdapat di dalam daun katu yaitu darun yang sering digunakan untuk pengobatan tradisional. Dari ekstrak ethanol 95% daun katu dapat diisolasi senyawa asam fenolat dengan cara fraksinasi sinambung menggunakan ether, dengan dan tanpa proses hidrolis. Fraksi eter kemudian dianalisis dengan menggunakan kromatografi kertas dua dimensi dengan larutan pengembang pertama asam aseta 2% dalam air dan larutan pengembang kedua benzene-asam asetat-air (60:22:1,2) dengan penampak bercak sinar ultra violet larutan diaze p-nitroanilin, sedangkan untuk memperjelas hasil disemprot dengan natrium karbonat 15%. Dari hasil identifikasi diperoleh asam fenolat, asam para hidroksi benzoate, asam ferulat, asam kafeat dan asam vanilat. Kecuai itu masih ditemukan lebih dari 7 bercak yang diduga sebagai asam fenolat. Setelah dilakukan analisis kuantitatif dengan menggunakan spektrofotodensitometer terhadap 4 jenis asam fenolat yang teridentifikasi maka diketahui bahwa asam p-hidroksibenzoat mempunya prosentasi tertinggi.

Isolation and Identification of Fenolic Acid in Katu Leaves (Sauropus Androgynus (L.) Merr. ). To improve traditional drugs in changing to fitofarmaka studies should be conducted on the chemical content of plants used as drugs. In this study, fenolic acid compounds in katu leaves, which are used for traditional medicine, were isolated and identified. From 95% ethanol extracts of katu leafs could be isolated a fenolic acid compound through continuous fraction using ether, with or without hydrolysis process. The ether fraction was then separated with the two dimension paper chromatography. The first solution developed was 2% acetic acid in water, and the second was benzene-acetic acid?water (60 : 22 : 1,2). Spots were identified with ultraviolet light, diazo p-nitroaniline solution and to enhance the color 15% sodium carbonate was sprayed. After separation p-hidroxy benzoid acid, ferulic acid, cafeic acid and vanilic acid were identified. In addition more than 7 spots were found which were supposed to be fenolic acids. Quantitative analysis was done using the spectrophotodensitometer for 4 kinds of identified fenolic acids. The highest percentage in katu leafs was p-hydroxibenzoid acid."
