The purpose of this study is to find out the job satisfaction of the korean medical clinic workers, and understand the factors that affect the satisfaction thereby increasing the efficiency of human resource management and providing the basic data to establish the management strategy. We visited 50 korean medical clinics which were chosen randomly from the korean medical clinics in the city of Changwon, Gyungnam. First, we explained the purpose of the study and survey contents to the surveyees, then distributed the Questionnaire and collected them. The data analysis was done statistically using the SPSS WIN IBM 20.0 program. The results were as follows: Professional career, interpersonal relationship, work autonomy, and overall job satisfaction showed significant differences depending on ages. While satisfaction of interpersonal relationship showed significant difference depending on final education. Depending on marriage status, while married persons showed significantly high satisfaction on professional career, interpersonal relationship, work autonomy, administration, and overall job satisfaction, there is no significant difference on income satisfaction. The number of years worked in the current clinic showed significant difference on administration satisfaction. Also, daytime working hours showed significant difference on administration and overall job satisfaction. The work area showed significant difference on overall job satisfaction. The income level showed significant differences on professional career, administration, and overall job satisfaction. From this study, it was confirmed that demographic characteristics and work environment factors showed significant differences on overall job satisfaction of workers in korean medical clinics. Therefore, in order to facilitate efficient manpower utilization and organization efficiency maximization, and motivation of human resources, a detailed plan should be developed to improve working environment and take demographic characteristics into consideration.

Purpose: This study was investigated basic data for verifying the effect of rope skipping exercise by comparing and analyzing the effects on the body composition of female students. Method: The subjects of this study were 12 female college students and the rope-skipping exercise program was conducted after the purpose and process of this study were explained and the consent of the subjects was obtained. And we used the body composition analyzer (Inbody 520, Korea) to measure before and after exercise of Body Mass Index (BMI), Percentage Body Fat (PBF) and Waist Hip Ratio (WHR). Result: First, the daily living group and the rope-skipping exercise group showed a significant difference in the BMI according to the period and there was no significant difference between the groups. Second, in the PBF, there were no significant differences in the duration, interaction between duration and group and differences between the groups. Third, in the WHR, there were no significant differences in the duration, interaction between duration and group and differences between the groups. Conclusion: BMI of each group according to the period was significantly different between before exercise and 6 weeks after exercise.

Dementia, characterized by a progressive cognitive decline and a cumulative inability to behave independently, is highly associated with other diseases. Various cardiovascular disorders, such as coronary artery disease and atrial fibrillation, are well-known risk factors for dementia. Currently, increasing evidence suggests that sex factors may play an important role in the pathogenesis of diseases, including cardiovascular disease and dementia. Recent studies show that nearly two-thirds of patients diagnosed with Alzheimer's disease are women; however, the incidence difference between men and women remains vague. Therefore, studies are needed to investigate sex-specific differences, which can help understand the pathophysiology of dementia and identify potential therapeutic targets for both sexes. In the present review, we summarize sex differences in the prevalence and incidence of dementia by subtypes. This review also describes sex differences in the risk factors of dementia and examines the impact of risk factors on the incidence of dementia in both sexes.

한국산 포유동물 6목 24종 279표본의 4개 외부형질과 22개 두골형질들을 측정하였으며, 측정치를 ordination법과 clustering법에 의해서 분석하였다. 형태적 분석의 결과는 족제비, 청서 및 토마스 땃쥐가 현존 분류체계상의 위치와 다르게 나타났다. 한국산 포유동물의 목 수준에서의 mrophological difference는 다른 포유동물보다는 크게 나타났으나, 목 이하의 수준에서는 별 차이가 없었다. 분류학적 체계에서의 단계가 높아질 수록 average taxonomic distance morphological difference의 수치는 커졌으며, 두 행렬식간의 상관계수는 0.59였다.

이 연구에서는 유아특수교사의 장애영유아 권리보장 수준에 대한 인식이 교사변인(성, 연령대, 근무경력)과 교육기관 변인(유형, 설립형태, 규모, 지역)에 따라 차이가 있는가를 알아보았다. 이를 위해 유아특수교사 365명을 대상으로 설문조사를 실시하였고, 자료분석은 t-검증 및 F-검증을 실시하였는데 그 결과는 다음과 같다. 첫째, 유아특수교사 성별 인식 차이는 없고, 둘째, 유아특수교사의 연령대별 인식 차이도 없으며, 셋째, 유아특수교사의 근무경력별 인식 차이도 없는 것으로 나타났다. 넷째, 교육기관의 유형별 인식 차이는 생존권, 보호권, 발달권, 참여권 영역 모두 차이가 있는 것으로 나타났다. 다섯째, 교육기관의 설립형태별 인식 차이는 생존권과 발달권은 차이가 있고, 보호권과 참여권은 차이가 없는 것으로 나타났다. 여섯째, 교육기관의 규모별 인식 차이는 생존권, 보호권, 발달권, 참여권 영역 모두 차이가 있는 것으로 나타났다. 일곱째, 교육기관의 지역별 인식 차이는 없는 것으로 나타났다. 이와 같은 연구결과는 장애유아의 교육권 증진을 위한 정책을 수립하는데 기초자료로 활용할 수 있을 것이다.

Our motivation in this note is to find equal hyperharmonic numbers of different orders. In particular, we deal with the integerness property of the difference of hyperharmonic numbers. Inspired by finiteness results from arithmetic geometry, we see that, under some extra assumption, there are only finitely many pairs of orders for two hyperharmonic numbers of fixed indices to have a certain rational difference. Moreover, using analytic techniques, we get that almost all differences are not integers. On the contrary, we also obtain that there are infinitely many order values where the corresponding differences are integers.

무선 센서망에서 이동노드의 위치를 추정하는데 센서노드의 클럭주파수 차이는 TOF 추정에 중요한 파라메타이며, 이동노드와 고정노드 간의 거리 추정에 크게 영향을 미친다. IEEE802.15.4a에서는 별도의 유선 등에 의한 망동기 공급이 없는 상태에서도 주파수 차이에 둔감한 비동기 TWR 및 SDS-TWR 거리 추정 방식을 제안하고 있다. 그러나 제안된 비동기 TWR 및 SDS-TWR 방식은 여전히 노드 쌍에 따른 주파수 차이, 프레임 처리 시간, 프레임 처리 시간 차이 등에 의한 영향을 충분히 제거하지 못하고 있다. 특히 주파수 차이가 큰 저가의 발진기 사용, 서로 다른 하드웨어 및 소프트웨어에서 동작하는 센서노드는 더 큰 위치추정 오류를 유발할 수 있다. 본 논문은 주파수 차이를 추정하는 방식을 제안하고, 기존의 TWR 및 SDS-TWR 방식에 적용하였다. 시뮬레이션을 통하여 주파수 차이 추정을 적용한 제안된 방식은 주파수 차이의 영향을 감소시켜 TWR 및 SDS-TWR 등의 성능을 개선시켰으며, 25cm 이하의 위치오류가 발생하는 것을 확인하였다.

This study examines the possible differences in satisfaction level according to the attributes classified as product, price, and service among women apparel consumers with the experience of buying global and domestic SPA brands. Data were collected through a survey of 270 women consumers aged 20s and with SPSS 15.0. The results are as follows: The exploration of the difference in product, price, and service attributes between the global and domestic SPA brands revealed that for product attributes, domestic brands scored higher in management quality, while global brands scored higher in design. In addition, for price attributes, domestic brands scored higher in promotion, while global brands scored higher in price value. When it comes to service attributes, only in regards to store policy was there a significant difference, with the score of global brands higher than domestic brands. The analysis of the difference in shopping orientation on domestic SPA brands showed significant difference only in customer convenience for the category of service attributes, while on global SPA brands, there were significant differences of the design for product attributes, promotion for price attributes, and customer convenience for service attributes.

The purpose of this research was to assess gender differences in the processes of intergenerational transmission of marital instability. This study revealed gender differences in the intergenerational transmission of marital instability. The fit indices suggest that the hypothesized model fit better for the female sample. Parental divorce marital quality and marital commitment were significant predictors of marital instability for both genders. Parental divorce was a strong predictor of marital quality for women only. While the path between age difference and marital quality for females was strong the same association disappeared for their male counterparts.
