This study aims to analyze the effects of the social capital of wage workers with acquired disabilities on organizational commitment, depending on the degree of their disabilities. The survey included 187 people with severe acquired disabilities and 606 people with moderate acquired disabilities, who participated in the 8th (2015) panel survey of employment for the disabled. Multiple regression analysis was performed: the results identified that the official network activity increased for people with both severe and moderate acquired disabilities and contributed to the improvement of organizational commitment. Further, women had a significant influence on organizational commitment. In the case of people with severe acquired disabilities, it was also found that, as social participation increased, organizational commitment decreased. In the case of people with moderate acquired disabilities, individuals who were healthier, more regular workers, and had higher qualifications had a greater positive the impact on the organizational commitment. Based on the results of this study, ways to increase social capital and organizational commitment of wage earners with severe and moderate acquired disabilities are suggested.

풍화작용에 의해 생성된 유사는 자연 매체에 의해 이동하고 하천에 도달하기 이전이나 이후 퇴적되며, 해당 과정 중에서 하상변동, 홍수위 상승, 제방 안정성, 두부 침식, 생태환경 변화, 수질문제 등 다양한 침식과 퇴적 관련 문제들이 발생한다. 이러한 유사 문제의 해결과 지속적인 하천관리를 위해서는 유사의 생성, 이송, 그리고 퇴적 과정에 대한 충분한 이해와 정량적인 유사량을 파악하는 것이 필수적이다. 다양한 연구들을 통해서 유사량을 정량적으로 파악하기 위해 여러 종류의 모델과 공식들이 제안 되어져 왔다. 그 중 경험적 모델의 경우 실제로 관측된 값을 기반으로 하며, 복잡한 계산이나 요구하는 자료가 다른 종류의 모델들 보다 적어 쉽게 접근이 가능하다. 이러한 경험적 모델은 유사에 영향을 주는 인자를 규명하거나 특정 유역이나 지역에서 이송 및 퇴적 되는 유사의 출처와 특성을 규명하는 초기 단계에서 유용하게 이용된다. 국내 하천의 경우 여름에 강우가 집중되고 대부분의 국토가 산지로 이루어져있어 상류에서 침식이 주로 발생한다. 또한, 본류 및 하류 지역의 하천은 유사의 퇴적이 주로 일어나서 하천의 형태와 물길이 형성된 충적 하천 형태로 발전 되어있기 때문에 국내 하천에서는 전반적으로 국부적이며 다양한 형태의 유사 관련 문제가 발생한다. 국내 하천에서 발생하는 유사 관련 문제를 해결하기 위해 국내 하천의 유사량을 추정하는 다양한 경험적 모델들이 지속적으로 개발되어왔다. 하지만 과거에 개발된 모델들의 경우 계측 자료가 충분하지 않은 시기에 개발 되었으며, 현재에는 활용하기 불가능하다. 본 연구에서는 국내 하천의 비유사량을 예측하는 동시에 국내 하천의 유사 특성을 이해하기 위해 과거에 국내 하천을 대상으로 비유사량을 추정하기 위해 개발되었던 경험적 모델을 개선하였다. 본 연구를 통해 기존 경험 모델의 경우 주기적인 업데이트가 필요함을 확인하였으며, 개발된 모델의 경우 국내 하천 유사 관리를 위해 미래 유사량 예측하는 등 다양한 방면으로 활용 관리가 가능할 것으로 보인다.

This study analyzed the relationship between communication perception and job performance in general hospital nurses in order to provide basic data for efficient personnel and hospital management. For this purposes, data were collected from August 5 to 23, 2019, targeting 392 nurses from 14 general hospitals in Gwangju and Jeonnam and t-test, variance analysis, post hoc analysis, Correlations analysis and multi-regression analysis were conducted. In analyzing the differences between demographical and health characteristics and job performance, there were statistically significant differences in age, working years, salary, satisfaction, locations, health status, health education, chronic diseases and depression. In respect to communication perception and job performance of nurses, age of 30 and job satisfaction (moderate satisfaction and dissatisfaction) had a negative effect, locations had a positive effect, and horizontal communication had the greatest effect on job performance. There was a relation between downward, informal and upward communication and job performance, and the determination coefficient was 45.2%. Based on these results, this study suggested that for higher job performance, we should improve working environment, enhance job satisfaction, organize nursing organization culture with active horizontal, downward, informal and upward communication and develop an efficient personnel management system.

This survey research was performed to determine the social capital that public officials generate within the relationship of the community at the individual level by performing their public office work as an administrative duty. To this end, a survey was conducted on 500 civil servants in Jeju province. The survey period was May 19-23, 2014. 476 subjects were analyzed using a T-test, One way ANOVA, and multiple regression analysis to on SPSS 19.0Win software. As a result of the analysis, 1. The norms of the community cultural, male staff participation and cooperation, and social capital level of civil servants, showed a significantly higher association than female civil servants. There was a difference between the populations of registration to an association to the work location type. In addition, the social capital increases generally as the level of the officers increases. 2. The sub-category in the social capital of a personal level on civil servants family & associates trust, participation & cooperation and neighbor trust had a positive impact on the efficiency of public services. On the other hand, community cultural associations (network) did not have an influence on efficiency.

Politics and conflicts within organizations are natural phenomena found in any type of organization, affecting organizational outcomes and output variables. Nevertheless, there are not many previous studies on politics and conflict within nursing organizations. Therefore, in this study, we would like to analyze how the internal politics and conflicts, which have been excluded from the previous studies related to nursing organizations, affect the quality of communication between nurses. Data were collected from 310 nurses in an university hospital. Using SPSS21, the data were analyzed by descriptive statistics, Pearson's correlation analysis, and multiple regression analyses. As results of the analyses, the organizational politics and relationship conflict have negative effect on the quality of vertical and horizontal communication, and task conflict has a positive effect on them. Organizational politics and relationship conflict have negative effects on quality of formal communication. Organizational politics and conflicts did not significantly affect the quality of informal communication. These results suggest that active, managerial efforts should be executed to overcome the negative effects of organizational politics and emotional conflicts among nurses. Furthermore, empirical research on organizational politics and conflicts within nurses organizations should be expanded.

The purpose of this study was to examine and compare factors affecting the subjective life expectancy among the elderly, and to suggest health practice and social welfare service implications for later life. A total of 4,483 seniors from the 6th wave(2016) of the Korean Longitudinal Study on Aging (KLoSA) were used for analysis. The subjects were divided into three age groups: the young-old (n=2,106, 65~74 years), middle-old (n=1,803, 75~84 years), and oldest-old (n=574, 85 years and older). Control variables were sociodemographic factors and health status factors. Independent variables were health promotion behavior, cognition of public care, participating social activity, economic activity, and receiving basic pension. The data were analyzed using hierarchical multiple regression. The main results were as follows. Health promotion behavior was associated with the young-old. Social activities and economic activity were associated with the young-old and middle-old. Receiving basic pension had a significant impact on all age groups. In the middle-old, significant results were focused on socio-demographic and health status factors compared to other groups. The results of this study will provide basic data for the elderly policy and welfare service and will help to find and improve the important factors for the life of the elderly.

This study was carried out to propose low types of green speed expectation models for fast putting green management by changing mowing height($4.0{\sim}2.5$ mm) and timing of rolling, dew removal and dew removal+rolling. Ball roll distance data were taken from the creeping bentgrass(Agrostis palustris Huds. 'Penncross') practice green of east course at the Lakeside C.C. in October 18, 2001 and May 25, 2002. Data were subjected to multi-regression analysis using Statistical Package for the Social Science. Among four types of green speed expectation models, the best multiple-regression equation for fast green management was as follows; $Y_4=4.171-0.225{\cdot}X_1-0.038{\cdot}X_2$ (where, $Y_4$ : green speed(m) after single dew removal+single rolling, $X_1$ : mowing height($4.0{\sim}2.5,\;X_2$ : passage of time ($0{\sim}8$ h.)). The equation[single dew removal by using sponge roller $\rightarrow$ single mowing at 3.0 mm height or less $\rightarrow$ single rolling] explained to provide fast green over 3.2 m (Stimpmeter readings required for USGA championship play) until the end of first round. Therefore, this cultural practice system was believed to provide fast putting green condition for professional golf tournament

Background: Measurement of the maximum oxygen uptake in patients with chronic obstructive pulmonary disease (COPD) has been used to determine the intensity of exercise and to estimate the patient's response to treatment during pulmonary rehabilitation. However, cardiopulmonary exercise testing is not widely available in Korea. The 6-minute walk test (6MWT) is a simple method of measuring the exercise capacity of a patient. It also provides high reliability data and it reflects the fluctuation in one' s exercise capacity relatively well with using the standardized protocol. The prime objective of the present study is to develop a regression equation for estimating the peak oxygen uptake ($VO_2$) for men with moderate to very severe COPD from the results of a 6MWT. Methods: A total of 33 male patients with moderate to very severe COPD agreed to participate in this study. Pulmonary function testing, cardiopulmonary exercise testing and a 6MWT were performed on their first visits. The index of work ($6M_{work}$, 6-minute walk distance [6MWD]${\times}$body weight) was calculated for each patient. Those variables that were closely related to the peak $VO_2$ were identified through correlation analysis. With including such variables, the equation to predict the peak $VO_2$ was generated by the multiple linear regression method. Results: The peak $VO_2$ averaged $1,015{\pm}392ml/min$, and the mean 6MWD was $516{\pm}195$ meters. The $6M_{work}$ (r=.597) was better correlated to the peak $VO_2$ than the 6MWD (r=.415). The other variables highly correlated with the peak $VO_2$ were the $FEV_1$ (r=.742), DLco (r=.734) and FVC (r=.679). The derived prediction equation was $VO_2$ (ml/min)=($274.306{\times}FEV_1$)+($36.242{\times}DLco$)+($0.007{\times}6M_{work}$)-84.867. Conclusion: Under the circumstances when measurement of the peak $VO_2$ is not possible, we consider the 6MWT to be a simple alternative to measuring the peak $VO_2$. Of course, it is necessary to perform a trial on much larger scale to validate our prediction equation.
