The purpose of this study is to investigate the prime factors that affect to user postoccupancy evaluation of activities and facilities in urban parks, to classify those factors, to find out factors about them, and then to suggest important indicators in the urban park planning, design, and development. The survey research was done using the self-administered questionnaire method by 435 peoples in the Busan City who participated in recreational activities in the Amnam Park. The Analysis of the data primarily consists of two phase: The first analysis was dealt an exploratory factor analysis which identified major factors involved in user postoccupancy evaluation with reacreational activities and facilities in Amnam Park by the SPSS(Ver.6.0) program and the second analysis was used to investigate the factors affected to user postoccupancy evaluation in the urban park by the Regression Analysis. According to the factor analysis, user postoccupancy evaluation of facilities in urban parks concerning the 20 variables, 5 prime factors by the staistical values were considered. The factor analysis showed that user postoccupancy evaluation of activities in urban parks concerning the 11 variables, 3 prime factors by the staistical values were analysed. Postoccupancy evaluation in the urban park by the Regression Analysis suggested that the two varlables as 'the directions of park development' and 'companies with the personal specific characteristics' are significant in addition to the some variables presented in user postoccupancy evaluation with reacreational activities and facilities in Amnam Park by the factor analysis. Furthomore the analysis models were identified as having significant effects on the factor and regression analysis. Overall fits of both models were very good. These significant relationships indicate important factors and variables that should be considered in planning, design, and development of the urban parks. Therefore, development direction of the h a m park has to be analyzed as significant factors concerning user postoccupancy evaluation in a systematic way, recognized as important variables for planning process. The urban park has to be fully designed and established in the planning process not by the decision-maker's subjective evaluation but by user postoccupancy evaluation.

박환석(Park, Hwan-seok),손성진(Son, Sung-jin) 한국국제회계학회 2020 국제회계연구 Vol.0 No.90

본 연구는 병원의 품질경영혁신(TQM) 활동과 조직성과의 관계에서 성과측정시스템(PMS)의 이용방식과 공정성이 매개역할을 하는지를 규명하고자 하였다. 연구목적을 달성하기 위해 투입 차원은 병원 TQM 활동의 수준으로, 전환 차원은 PMS 진단 및 상호작용적 이용방식과 PMS 공정성 수준으로, 산출 차원은 조직의 성과(구성원 태도, 재무/비재무성과)로 설정하였다. 연구가설 1은 병원 TQM 활동의 수준과 조직성과의 관계, 가설 2는 그 관계에서 PMS 이용방식의 역할, 그리고 가설 3은 병원 TQM 활동수준, PMS 이용방식, PMS 공정성, 그리고 조직성과의 순차적인 인과관계를 규명하는 것이다. 본 연구의 결과는 다음과 같다. 첫째, 병원의 TQM 활동수준은 구성원 태도와 비재무성과에 정(+)의 영향을 미쳤다. 그러나 재무성과에는 유의한 영향을 미치지 않았다. 둘째, 병원의 TQM 활동수준과 조직성과의 관계에서 PMS 진단적 이용은 매개역할을 하였으나, PMS 상호작용적 이용은 매개역할을 하지 못하였다. 셋째, 병원이 TQM 활동을 추진하면서 PMS 진단적 이용을 선택한다면 구성원의 태도 변화를 경유 하여 재무/비재무성과가 개선되었다. 그런데 PMS 상호작용적 이용을 선택한 경우에는 PMS의 공정성 수준이 높아져야지만 구성원의 태도가 변하고 재무/비재무성과의 개선으로 연계되었다. 본 연구는 병원이 TQM을 추진하는 과정에서 경영통제 차원에서 성과측정시스템을 적절히 관리하고 인적자원관리 차원에서 구성원 태도를 변화시키려는 노력은 병원조직성과의 개선에 공헌할 수 있다는 점을 시사하고 있다. This study is aimed to investigate whether use of performance measurement system (PMS) and justice of PMS play a mediating role in the relationship between TQM activities of hospital and organizational performances. We defined TQM activities of hospital as input variable, diagnostic and interactive use of PMS, justice of PMS as conversion variables, and organizational performances (attitude of internal members, financial / non-financial performances) as output variables in order to test hypotheses. Hypothesis 1 is to test the relationship between level of TQM activities of hospital and organizational performances. Hypothesis 2 is to explore a mediating role of the diagnostic and interactive use of PMS in the relationship. And Hypothesis 3 is to identify casual relationship among TQM activities of hospital, the diagnostic and interactive use of PMS, the justice of PMS, and the organizational performances. The results of the study are as follows. Firstly, the TQM activities of hospital have a positive effect on the attitude of internal members and non-financial performance. However, the effect of TQM activities of hospital on financial performance are not significant. Secondly, the diagnostic use of PMS has played a mediating role in the relationship between the TQM activities of hospital and the organizational performances, but the interactive use of PMS does not play a mediating role in the relationship. Thirdly, if hospital use the diagnostic control of PMS in the process of promoting TQM activities, financial / non-financial performances have improved through changes in the attitudes of internal members. However, in case of using the interactive control of PMS, the attitude of internal members changed as the justice of PMS increased, which is linked to improvement of financial / non-financial performances. This study suggests that efforts in the process of pursuing TQM activities trying to manage properly performance measurement systems in management controls and to change employee attitude in terms of human resource management can contribute to improve the organizational performances of hospital.

Background : To exatnine the problems intolved in writing practice of death certificates, we cotnpated the determination of underlying cause of death for wital statistics using recorded underlying cause of death in issued death statistics. Methods : We collected 688 rnortality certificates issue in year of 2,000 from 3 university hospitals. And we also collected vital statistics from ministry of statistics. The causes of death were coded by experienced medical record wpecialists. And causes of death determined at ministry of statistics for national vita statistics were mapped to causes of death recorded at each death certificates. The rate that underlying causes of death for vital statistics were derived from underlying causes of death recorded at issued death certificaties sere analysed. Results : 64.5% of underlying cause of death for could be derived from underlying cause of death recorded at issued death certificates, 8.6% derived from intermediate cause of death, and 3.9% derived from direct cause of death. In 23% of cases, underlying cause of death could not be derived using issued death certificates. The rate that underlying cause of death for vital statistics could be derived from underlying cause of death recorded at death certificates was different between 3 university hospitals. Ane the rate was also different between death certificates and postmortem certificates. We classified the causes of death using 21 major categories. The rate was different between diseases or conditions tha caused death too. Conclusion : When we examined the correctness of death certificate writing practice using abpve methods, cortectness of writing could not be told as satisfactory. There was difference in correctness of writing between hospotals, between death certificates and postmortem certificates, and between diseases and conditions that caused death. With this results, we suggested some strategy to improve the correctness of death certificate writing practice.

This study was performed to compare the effects of chaff and sawdust as bulking materials on temperature, pH, weight and volume reduction and salinity in aerobic composting of food wastes. Volume ratios of food wastes to chaff in reactor Control, Ch-1, Ch-2, Ch-3 and Ch-4 were 4:0, 4:1, 4:2, 4:3 and 4:4, respectively. Volume ratios of food wastes to sawdust in reactor Control, Sd-1, Sd-2, Sd-3, and Sd-4 were 4:0, 4:1, 4:2, 4:3 and 4:4, respectively. Reactors were operated for 24 days with 1 hour stirring by 1 rpm and 2 hours aeration per day. The lowering of the volume ration of food wastes to chaff and sawdust resulted in the ascending of the highest reaction temperature and the elongation of the high temperature reaction period. The lowering of the volume ratio of food wastes to chaff and sawdust resulted in the more fast time of pH ascending. In the volume ratio of 4:3 and 4:4, the time of pH ascending of chaff mixtures were more fast than those of sawdust mixtures. The lowering of the volume ration of food wastes to chaff and sawdust resulted in the more fast consistency in the weight reduction rate and the volume reduction rate. The weight reduction rates of chaff mixtures were higher than those of sawdust mixtures, but the volume reduction rates of sawdust mixtures were more higher than those of chaff mixtures. Salinities were condensed by reaction days. The final salinity of Control was 2.79%, and the final range of salinities of chaff and sawdust mixtures were 2.18 - 2.37% and 1.86 - 2.05%, respectively.

This study was performed to define the effects of the cattle feces on aerobic composting of food wastes in vessel system. Weights of cattle feces added to food wastes of 3 kg were 0.25, 0.50, 100 and 1.50 kg, respectively. Reactors were operated with stirring for 1 hour per day by 1 rpm and aeration for 2 hours per day. When the weight of cattle feces was increased, the highest temperature of sample was increased, the duration period of higher temperature was elongated, and the fluctuation of pH was severe. When the weight of cattle feces was decreased, the final density was increased. The more cattle feces were added, the more porosity was increased, C/N ratio. salinity and conductivity were decreased. These facts denotes that the addition of cattle feces increases the efficiency of composting process and the final product of composting, namely compost.

This study was performed to define effects of rice straw as bulking material on aerobic composting of food wastes. Volume ratios of food wastes to rice straw in reactor control, RS-1, RS-2, RS-2 and RS-4 were 4:0, 4:1, 4:2, 4:3 and 4:4, respectively. Reactors were operated for 24 days with 1 hour stirring by 1 rpm and 2 hours aeration per day. pH of food wastes was 4.39, and that of rice straw was 7.4. C/N ratio and porosity of rice straw were 2 times of those of food wastes. Salinity and conductivity of food wastes were higher than those of rice straw. With the increasing of volume ratio of food wastes to rice straw, times needed to arrive at 50℃, the weight reduction rate of 60% and the volume reduction rate of 40% were shortened, the highest temperatures of reactors were increased, and the durations of 50℃ over were elongated. C/N ratio of 29.5 in control was more than those of 25.7-28.1 in rice straw containing reactors. Salinity and conductivity in reactors were condensed and increased by reaction day, and the correlation coefficient(r) between these two indices was 0.9967.

웹기반의 가축전염병 발생자료 관리시스템(AIMS) 개발

박병호,김석재,황인진,김시동,남향미,위성환 한국농업정보과학회 2003 농업정보과학 Vol.4 No.1

The AIMS(Anima1 Infectious Disease Data Management System) was developed to collect and analyze data on animal infectious disease outbreak (62 diseases). When an animal infectious disease is confirmed at a diagnostic laboratory, the disease outbreak is then reported to the regional government through AIMS. After the regional government confirms the number of animals infected or dead, outbreak date and etc, this information is reported to the Ministry of Agriculture & Forestry and the National Veterinary Research & Quarantine Service through AIMS. The AIMS analyzes the outbreak data and reports the outbreak statistics by region, month and year to them. In addition, the AIMS can identify the farm where there was an outbreak of the animal infectious disease. There are four user roles : 1) Administrator, responsible for the overall operation of the system. 2) Inspector, responsible for confirmation of the animal infectious disease outbreak. 3) Pathologist, responsible for input to an animal infectious disease at first. 4) Gallery, only able to read the outbreak statistics. The AIMS has been implemented using the ASP technology and is operated on the web to allow easy access. The data, middle and presentation tier are based on MS-SQL 2000 server, Microsoft transaction server and Internet Explorer, respectively. The database's stored procedure was used to improve the performance. In addition to above software, the dextupload software is used to upload the files. By using the AIMS, a more accurate statistics for the animal infectious disease outbreak is expected.
