A comparison between two species of Hyla japonica and H. suweonesis in Korea was carried out to clarify their morphological, genetic and ecological differences, to estimate presumed divergent time between them, and to elucidate their probable process and mechanism of speciation. The results are as follows; 1.The breeding season of H. japonica was earlier than that of H. suweonensis about one and half months. 2.H.japonica was distributed all over the country, while H. suweonensis was restricted in Kyonggi plains. 3.On the extemal morphometric characters, differences were hardiy seen between two species. But on the discriminant function analysis, there was apparent differences between them. 4.Genic variation based on 24 loci showed that H. japonica populations were about two fold more variable than that of H. suweonensis populations. 5.Genetic relatedness between two species was rather remote (S =0.520, D=0.634) 6.Their presumed divergent time was estimated to be about three and a quarter mfllon years. It is presumed that H. suweonensis was originated from H. japonica during the period of late pleocene and early pleistocene. 7.Premating isolating mechanisrns (breeding season, mating call, and microhabitat segregation) may be operating to prevent gene ifow between them.

This study was conducted to develop a severity-adjusted LOS(Length of Stay) model for knee replacement patients and identify factors that can influence the LOS by using the Korean National Hospital Discharge in-depth Injury Survey data. The comorbidity scoring systems and data-mining methods were used to design a severity-adjusted LOS model which covered 4,102 knee replacement patients. In this study, a decision tree model using CCS comorbidity scoring index was chosen for the final model that produced superior results. Factors such as presence of arthritis, patient sex and admission route etc. influenced patient length of stay. And there was a statistically significant difference between real LOS and adjusted LOS resulted from health-insurance type, bed size, and hospital location. Therefore the policy alternative on excessive medical utilization is needed to reduce variation in length of hospital stay in patients who undergo knee replacement.

This study is a descriptive research to grasp the effects of nursing performance on emotional labor, job stress and resilience in general hospital nurses. Method: I surveyed them using a structured questionnaire for collecting data from Aug. 20, 2019 to Sep. 2, 2019. The collected data were analyzed by the frequency, the percentage, t-test, ANOVA, Scheffe's Test, Pearson's Correlation Coefficient, and Multiple Regression Analysis. Results: The factors affecting nursing performance of the subjects were resilience (β=0.58, p<.001), and current position is head nurse (β=0.21, p<.01), the number of working years at current working place (β=0.18, p<.05). The F statistics for the fit of the estimated regression model was very significant as 30.901(p<.001) and the explanatory power was 42.4%. Conclusion: The results of this study showed that resilience was the most influential factor to nursing performance of general hospital nurses, and the number of working years at current working place was the most influential factor to the performance of head nurses. Therefore, it is necessary to develop practical programs strengthening resilience of nurses for the improvement of nursing performance and to apply strategies on development.

Healthy Japan 21의 목적은 삶의 질을 향상시킴은 물론 노동가능 인구집단의 유병률을 줄이고 건강수명을 연장시키기 위하여, 21세기 모든 일본인들이 더욱 건강하고 행복한 삶을 향유할 수 있도록 국가사업을 활성화하는 것이다. 구체적 목적은 조기사망을 예방하고 건강생활을 향상하는 것으로, Healthy Japan 21의 전략적 기획과정에서 건강수명의 연장을 실현하기 위하여 2010년까지 달성되어야 하는 구체적인 목적들이 또한 제시되었다. 조기사망을 감소시키기 위하여 사고, 암, 자살, 심장병 감소의 중요성을 인식하고 9개의 주요 목표로 영양, 신체활동, 휴식과 이완, 금연, 절주, 구강보건, 당뇨병 예방, 심혈관계질환 예방, 암 예방을 설정하였다. 흡연, 알콜, 식사 그리고 운동과 같은 생활양식은 스트레스, 비만, 고혈압과 같은 위험요인 및 질병관리와 관련이 있으며, 위험요인은 암, 심장병, 구강질환의 발생과 밀접한 관련을 갖는다. 따라서 질병의 발생을 예방하기 위해서는 건강증진과 일차예방이 강조되어야 한다. 일차예방에 중점을 두기 위해서 우리는 전통적인 질병관리의 중점사항인 정기적인 건강검진을 통해 질병 조기발견을 노력을 게을리 하지 말아야 할 것이다. 아울러 의료비 감소, 병상에 있는 사람들의 감소, 사회세의 감소도 또한 달성되어야 하는 사업의 결과로 설정되어 있다. 가장 최근의 Healthy Japan 2000(1998-99)의 평가에 따르면 목표들의 15%가 달성되었거나 초과 달성된 것으로 나타났다. 이 중 아동과 청소년의 사망률의 경우, 1-14세 아동의 사망률은 1987년부터 26%가 감소되어 2000년도 목표인 인구 100,000명단 28명의 사망을 초과 달성한 것으로 평가되었다. Healthy Japan 21의 두 가지 주요 전략은 일반 인구집단을 위한 전략과 고위험 집단을 대상으로 하는 전략으로 구성된다. 개인의 건강한 생활양식으로의 변화를 포함한 우리의 건강증진 노력은 사람 중심으로 개인의 선택을 기반으로 하고 있다. 이러한 노력을 지원하기 위하여, 각 개인이 정보를 갖은 상태에서 올바른 선택을 할 수 있도록 적당량의 올바른 정보를 제공하는 것이 필수적이다. 이와 같은 일본의 건강증진계획은 2000년 3월에 Healthy Japan 21이 설립되었으며, 2000-2002년 사이 모든 현이 자신의 사업계획을 설정하였으며, 2001-2005년에는 약 반수 정도의 지방자치단체들이 자신들의 사업계획을 확정하였다. 건강증진을 이루는 중요한 수단은 파트너 쉽에 있다. 정부조직 뿐 아니라 건강보험회사, 보건의료서비스 제공자, 교육단체, 대중매체, 사기업, 봉사단체 등을 포함한 건강분야의 조직들은 자신들의 전문적 기술들을 한데 모아 서로 협력하여야 한다. 또 하나의 중요한 수단은 건강 지지적인 환경이다. 개인의 건강증진 노력을 체계화함으로써 지지적인 환경을 조성할 수 있다. Healthy Japan 21에 대한 평가는 2005년에 중간평가가, 2010에 최종평가가 있을 예정이다. 평가결과들은 이후에 진행될 사업의 향상을 위한 기준으로 활용될 예정이다.

This study was conducted to investigate the perception of nurse's use of physical restraints. This study is a descriptive research study for 138 nurses who work at the small hospitals under 300 beds. Statistical analysis was performed using descriptive statistics, t-test, ANOVA, and factor analysis using the SPSS statistical program. The results of this study were as follows: The overall average of the nurses' perception of physical restraint was $3.91{\pm}0.54$, and the most important reason for using a physical restraint was to protect the patient from falling out of bed($4.37{\pm}0.68$). The factor analysis showed that 'behavior, psychological symptom management($3.81{\pm}0.67$)', 'maintain medical treatment($4.11{\pm}0.60$)' and 'patient safety($4.13{\pm}0.63$)'. It is necessary to understand the characteristics and factors of nurse's use of physical restraint in small and medium hospitals. Moreover, it is also required to use minimum physical restraints for patient's safeties and rights based on accurate understanding of physical restraint's use. Therefore, it is needed to provide job training for the physical restraint that is used in various situations and to develop education and intervention program to adjust in nurses' situation.

The purpose of this study is to analyze the service area of emergency medical centers using GIS-based spatial analysis methods in Seoul, focusing on the behaviour of patients on the choosing of emergency centers. For this analysis, six emergency centers were selected to collect data for the information on the addresses of patients from September to November hi 2003. Analysis on the service area, which was carried out by measuring the distribution of patients in terms of distance from emergency medical centers, clearly reveals that the majority of patients was located within or adjacent districts at the emergency medical center. However, the size of the primary service area f3r six emergency medical centers was much different, implying that the decision to visit specific emergency medical center by patients was closely related to the size, perception, and preference of the emergency medical center. Based on the results of the spatial characteristics of emergency medical service area, this research tries to construct the surface map of the emergency medical service level supplied by 32 regional emergency medical centers located in Seoul. Considering the levels of infrastructure for emergency medical centers, the coverage for the degree of supply of emergency medical service by each emergency medical center was constructed in terms of a distance decaying in the distribution of patients from emergency medical center imposing different weights on distance bands. Spatial overlay utilizing map algebra function was performed in order to calculate total supply level of emergency service. The results clearly show that spatial inequality exists in the supply levels of the emergency medical service among local areas of Seoul.

Nursing service quality can vary depending on the work attitude and behavior of nurses. Nursing attitude and behavior that can be described as voluntary and proactive organizational citizenship behavior(OCB). OCB affects the work performance of nurses in clinical practice is very important and organizational justice is an important influencing factors of OCB. The purpose of this study was to determine the influential factors of organizational justice on OCB of nurses. The descriptive-correlational method was applied. The study was carried out less than a 500-bed hospital. Participants of the study included 230 nurses working in secondary hospitals. Data were analyzed using descriptive statistics, t-test, ANOVA, Pearson's correlation coefficient and multiple regression with the 18.0 SPSS/Window program. Considering the components of organizational justice, there was a significant positive correlation(r=.172~.540, p=.000) between OCB and distributive, procedural and interactional justice. Also, Total organizational justice explained 29.1% of total OCB with influencing factor (${\beta}$=.540) and was statistically significant(F=93.777, p=.000). The influencing factors to OCB were distributive justice(${\beta}$=.283) and interactional justice(${\beta}$=.249) except procedural justice. The findings suggest that strategies of nursing management are needed to focus on distributive justice for compensation and interactional justice for social relationship in order to induce nurses' organizational citizenship behavior.

The problems related with blood supply shortage and the stability of blood transfusion are on the rise, as it is expected that the blood doners will decrease but the blood use amount for aged population will increase, owing to low birth and aged population increase. The purpose of this study is to analyze the hospital characteristics which affect patients receiving and non-receiving blood transfusion for the knee and hip total replacement arthroplasty. Data were collected from Health Insurance Review and Assessment Service's 2011 sample data, and 5,370 inpatients were abstracted from them. Logistic regression analysis was performed, using SPSS 20. Independent variables used are hospital characteristics variables and patient characteristics variables. Hospital characteristics variables are hospital type, ownership, residence and the number of usable beds, and patient characteristics variables are gender, age, severity, type of anesthesia, main diagnosis, whether or not of anemia and insurance class. At the result of this study, it was found that hospital type, region, gender, age, severity, main diagnosis and whether or not of anemia were the factors that mostly affected the blood transfusion for knee arthroplasty. And hospital type, residence, gender, age, severity, type of anesthesia and whether of not of anemia were the factors that mostly affected the blood transfusion for hip arthroplasty. In addition to that, it is expected that this research which analyzed the present state of blood transfusion and its influence factors are cost effective, and would make a good use of preliminary data for good quality of medical service.
