With the introduction of the diagnosis procedure combination (DPC) system, the reduction of the health expenditure is expected. The use of generic drugs is promoted. It is imperative for introduction of generic drugs to assure the appropriate use of drugs to decrease medical costs without reducing medical services. Additionally, we should make a concerted effort to prevent the injudicious use of antimicrobial agents resulting in the emergence of drug resistance. In this study, we assessed the effects of switching to generic antimicrobial drugs on drug purchases cost, AUD (antimicrobial use density), hospital days, and antimicrobial susceptibility of Pseudomonas aeruginosa. This study was carried out at Yashima General Hospital for the period from April 2008 to September 2011. The Health, Labor and Welfare Ministry designated Yashima General Hospital as a DPC hospital from July 2009. Since the DPC introduction, the drug purchase cost has been decreased about 40% without reduction of AUD, hospital days, and antimicrobial susceptibility of Pseudomonas aeruginosa. Hospitals are making efforts to assess and improve management efficiency while maintaining the quality of medical care. Our results suggested that the introduction of generic drugs with assessment of efficacy may be one of the useful methods for pharmacy management.

Investigation on the working time, energy expenditure and fatigue were carried out for members of three families engaged principally in raising silk worms.
Group examinations of physical conditions and blood constituents and survey of nutritional intake were performed on the residents, including the above families, in a community in Fukueisland, Nagasaki-prefecture.
The results were as follows;
1) The average values of energy expenditure on a most busy day in a raising period of silk worm calculated to be 3150 kcal (max. 3500 kcal) for males, 2340 kcal (max. 2890 kcal) for females of the above three families. Their working times on this day were about 14 hours.
2) The physical fatigue of the subjects was estimated by means of Fliker frequency, near point and threshold of patellar reflex. Remarkable changes of these values were found, suggesting the heavy physical load of the raising works, and the changes were more remarkable in olders and females than in youngers and males.
3) Donaggio's reaction and Na/K in the first urine of morning were investigated at an interval of five days during one period of silk worm raising.
The Donaggio's reaction values were increased about two times higher in the latter term, on the other hand Na/K dropped in the former term of the period.
4) The group examinations of the inhabitants in the community showed that the body fat of silk raising farmers were fewer than that of the farmers engaged in other kinds of farming reported by the present authors.
Blood values (Ht, Hb and TP) of them in 1975 were lower than in 1974, because one more raising period was added and so the physical load of them might be greater in '75 than in '74.
5) The nutritional intakes of silk raising farmers were almost as same as these of the farmers in other districts.
