This study was done to develope a computer program for the evaluation of quality of nurisng care. Because the professional nursing care should be evaluated consistantly, computer program for the measurement of quality of nursing care is necessary for the effective and efficient management of nursing quality. In this study, a computer program for gastrointestinal surgery patients was developed as a module. Visual basic 4.0 was used as a basic program for the development of this program, and Access 7.0 was used for the data base construction of the program. The systems of evaluation criteria were hierarchical. and the titles of the hierarchical criteria were evaluation area-evaluation item-indicator. Each evaluation area contained several items and each evaluation item contained several indicators. The numbers of the evaluation criteria for gastrointestinal surgery patients were 7 evaluation areas, 32 evaluation items. and 71 indicators. Content validity of the evaluation criteria(in this case, 32 evaluation items) was .95. Scoring could be possible with the evaluation items. For the scoring types of this program were two. norm-referenced type(option 1) and criterion-referenced type(option 2), the user can choose the type according to the purpose of the evaluation. With this computer program. accurate and consistant evaluation of the quality of nursing care could be expected. Also. by the rapid feedback to nursing care practice. quality of nursing practice could be improved rapidly. and the systems of the evaluation criteria developed in this study could be used for the development of other moduls for various kinds of patient groups. Because this computer program was developed only for the purpose of research, it is necessary to be refined commercially to be used in real nursing situation.

Background: Concerns have been raised regarding the criteria of groundwater, in particular in Gwangwon-do Province where many residents drink groundwater due to the poor supply of tap water and a high nonconformity rate with water quality criteria nationwide. Objectives: Water quality monitoring and risk assessment were conducted for groundwater in Hoengseong, Gangwon-do Province. Methods: A total of 46 items required for meeting drinking water criteria were analyzed from 258 samples collected from March 2017 through August 2018 (152 sites in 2017 and 106 sites in 2018). Risk assessment was conducted for two non-carcinogens (F^- and NO₃-N), and one carcinogen (i.e., arsenic) based on their high nonconformity to water quality criteria. Results: Water quality analysis revealed that the total proportion of nonconformities was determined to be 27.9%. The nonconformity rate for each content item is as follows: total colony counts (1.6%), total coliform (6.2%), Escherichia coli (1.2%), F^- (8.1%), arsenic (4.7%), NO₃-N (8.1%), pH (1.2%), manganese (0.4%), and turbidity (5.8%). Risk assessment indicated that fluoride induced a hazard quotient greater than 1 with the 95% UCL (Upper Confidence Limit) concentration of the total 258 sites and average, median, and 95% UCL concentrations of nonconformity sites. For NO₃-N, there was no human health risk. For arsenic, the excess cancer risk exceeded the acceptable cancer risk of 1×10^-6 with the average and 95% UCL concentrations of total 258 sites and average, median, and 95% UCL concentrations of nonconformity sites. Conclusions: This study suggests that it is necessary to expand water quality monitoring of groundwater and conduct a more detailed risk assessment in order to establish a health care plan for the residents of Hoengseong, Gangwon-do Province.

최근 국내 석산에서의 골재공급이 부족해지면서, 성토재 등의 저급재료로 재활용 되던 폐 콘크리트 순환골재의 용도를 점차 구조용 콘크리트 및 도로 포장재와 같은 고급재료로 재활용하기 위한 노력이 계속되고 있다. 이러한 노력의 일환으로 정부는 2009년 순환골재 품질기준을 제정하였으며, 순환골재가 기존보다 고급재료의 용도로 활용될 수 있는 제도적 기반을 마련하였으나, 현재까지 빈배합 콘크리트 기층용으로서의 순환골재의 활용은 매우 낮은 형편이다. 본 연구는 순환골재 품질기준에 규정되어 있는 빈배합 콘크리트용 순환골재의 이물질과 관련된 품질기준의 적정성을 일련의 실험을 통하여 평가하였다. 연구결과, 빈배합 콘크리트 기층용 순환골재 내의 폐 아스콘 골재는 강도에 악영향을 초래하는 반면, 아스콘의 특성으로 인하여 순환골재의 주요한 품질기준인 비중을 높이고, 흡수율 및 마모율을 오히려 낮추는 결과를 초래하여, 전체적인 순환골재의 품질을 평가하는데 큰 방해요소로 작용하였다. 따라서 이물질 함유량 기준 중, 폐 아스콘 함유량 기준은 개선의 여지가 있는 것으로 조사되어, 그 대안을 제시하였다.

Three typical biological solid wastes, namely, animal manure, garbage, and sewage sludge, were compared with regard to the composting process and the changes in microbial community structure. The effects of different bulking agents such as rice straw, vermiculite, sawdust, and waste paper were compared in manure compost. The differences in the microbial community were characterized by the quinone profile method. The highest mass reduction was found in garbage composting (56.8%), compared with manure and sludge (25% and 20.2%, respectively). A quinone content of $305.2\;{\mu}mol/kg$ was observed in the late stage of garbage composting, although the diversity index of the quinone profile was 9.7, lower than that in manure composting. The predominant quinone species was found to be MK-7, which corresponds to Gram-positive bacteria with a low G+C content, such as Bacillus. The predominance of MK-7 was especially found in the garbage and sludge composting process, and the increase in quinones with partially saturated long side-chains was shown in the late composting process of manure, which corresponded to the proliferation of Actinobacteria. The effects of different bulking agents on the composting process was much smaller than the effects of different raw materials. High organic matter content in the raw materials resulted in a higher microbial biomass and activity, which was connected to the high mass reduction rate.
