Purpose: This study examined the impact factors of cesarean section based on the ecological approach in Korea. Methods: Population-based data (Korea Institute for Health and Social Affairs) were used from 2,849 delivery cases during 2003~2009. Data were analyzed using geographic statistics with STATA 10.0 and hierarchical logistic regression with SPSS/WIN 12.0. Results: The range of cesarean section rate was 28.8~44.7% with geographic distribution. The proportion of mother's problem was increasing in choice of cesarean section. According to the ecological model, age of mother (OR=1.08), time of birth (OR=0.79), delivery in hospital (OR=1.83), delivery in clinic (OR=1.46), and education of mother (OR=2.61) had significant impact on cesarean section. Conclusion: This study contributes to provide the impact factors of the high cesarean rate in Korea ecologically. Policy maker and health care provider can consider these results to reduce cesarean section rate.

This study aims to identify the factors influencing residents' satisfaction for the urban regeneration projects in South Korea. Data were collected from 250 people with self-administrated questionnaires. A factor analysis identified three factors which are positive economic impacts, negative social impact, and positive environment impact. The positive economic impact has the highest variance explained. Results showed that high income and students and unemployed are less like to be satisfied with their community life. And whereas negative social impacts are less likely to have community satisfaction, positive economic impacts are more likely to have community satisfaction. This study suggested that community leaders and policy makers should consider perceived impacts and income when implementing development projects.

A Scientometric Study SCI Impact Factors of Major Korean Medical Jernals: 1991-1999 본 연구에서는 SCI학술지가 아니라서 Journal Citation Reports(JCR)를 통하여 영향력지표 값을 쉽기 알 수 없는 학술지들의 영향력지표값을 JCR 방식으로 산출함으로서, 한국 의학 학술지들의 구체적인 학술지 평가지표를 제시하고 국제적인 위상을 객관적으로 파악하였다. 1969년부터 1998년까지 10년간 의학분야의 국내학술지 8종에 발표된 7,779편의 논문을 대상 으로 SCI검색을 하여 연도별로 인용빈도를 측정하고 1991년부터 1999년까지의 학술지 영향 력지표를 JCR과 동일한 방식으로 계량하여 분서하였다. 한글학술지 4종의 경우에는 국내학 자들이 SCI논문을 많이 발표하는 분야의 대표적인 학술지임에도 불구하고, SCI 인용을 거 의 찾아볼 수 없었다. 영문학술지 4종에 대한 SCI 인용빈도는 1994년경부터 계속 늘어나고 있으며, 특히 1997,8년경부터는 인용주기가 짧아져서 최근 2,3년간 발표된 논문에 대한 인용 이 급증하고 있고, 따라서 영향력지표값이 높아지고 있는 것은 매우 고무적이다. 한국 의학 학술지들의 10년치 영향력지표값 평균은 0.002에서 0.126까지 분포하였으며, YMJ의 1999년 도 영항력 지표값이 0.331로 가장 높았다. 한글학술지들의 영향력지표값을 같은 분야의 SCI 학술지들과 비교하여 보면, 모두 SCI 등재학술지의 최하위 영향력지표겂보다 낮았고, 영문 학술지는 대개 최하위권이어서 한국학술지의 국제적 위상은 매우 낮은 것으로 나타났다. 한 국 의학학술지 3종은 1990년대 후반 영향력지표값이 0.2 정도가 되었을 때 SCI에 등재되기 시작하였는데, 이들은 모두 영문학술지들이다. 영문으로 발행되는 현재 MEDLINE 학술지인 KJP는 1999년의 영향력지표값이 0.198로서 SCI등재 가능성이 있는 학술지로 판단된다.

The direction of the applied load and displacement rate on the femur during falls may be an important factors in the etiology of hip fractures. Nonetheless, previous studies did not consider these two factors simultaneously for falling condition. Therefore, in the present study, an impact test system is developed to simulate the falling condition and the influence of impact angle on the deformation pattern changes of proximal femur is investigated. The results showed that a slight variation in impact angle quite affects deformation pattern of the proximal femur. Along with bone mineral density and trabaecular morphology, the impact angle can be another important factor affecting the structural capacity of the proximal femur.

This study presents a more comprehensive approach to investigate how Emotional Intelligence (EI) is associated with performance. Previous research has revealed that EI is related to positive outcomes such as better performance, life satisfaction and career success. However, in most research of EI, this factor has been investigated independently from the effect of contextual factors and other individual characteristics. This study extended the research on the impact of EI on student performance by simultaneously examining the impact of EI, individual factors - (1) Perseverance of Effort, (2) Goal Consistency and (3) Goal Clarity and learning environment factors - Program Fit in one study. The results based on the data collected from 1,117 students in Vietnam largely support the hypothesis that that EI was an important but not the only factor affecting the student performance. MANOVA and post-hoc analysis indicated that both individual and environmental factors better predicted performance than EI could. These results suggest that the impact of EI on individual performance is more complicated than what we have already known. Future study is encouraged to investigate both the mechanism through which EI impact individual performance and the interaction between EI and other factors that moderate the EI - performance relationship.

In this paper, we propose a 3-D finite element (FE) analysis model with combined physical behavior and kinematical impact factors for evaluation of residual stress in multi-impact shot peening. The FE model considers both physical behavior of material and characteristics of kinematical impact. The physical parameters include elastic-plastic FE modeling of shot ball, material damping coefficient, dynamic friction coefficient. The kinematical parameters include impact velocity and diameter of shot ball. Multi-impact FE model consists of 3-D symmetry-cell. We can describe a certain repeated area of peened specimen under equibiaxial residual stress by the cell. With the cell model, we investigate the FE peening coverage, dependency on the impact sequence, effect of repeated cycle. The proposed FE model provides converged and unique solution of surface stress, maximum compressive residual stress and deformation depth at four impact positions. Further, in contrast to the rigid and elastic shots, plastically deformable shot produces residual stresses closer to experimental solutions by X-ray diffraction. Consequently, it is confirmed that the FE model with peening factors and plastic shot is valid for multi-shot peening analyses.

Side impact with MDB (moving deformable barrier) is common in side crash test protocols around the globe, most of which are quite similar to that of US NCAP side impact protocol but IIHS side impact protocol is considered to be the most harsh one due to the MDB's weight and impact speed. In this study US NCAP side impact and IIHS side impact test conditions are compared with respect to delta-V (impulse of the test vehicle), roll speed, and yaw speed as well as survival space (the smallest distance between the front driver seat cushion center to B pillar after the test). Error factors (friction between tire and ground, tolerance of vertical and longitudinal position of the MDB with respect to the test vehicle), which are resident in the test protocol is studied with respect to the global vehicle behavior (delta-V, roll, yaw) as well as survival space.
