This paper deals with an experimental study on the dynamical characteristics of ship motion during trawling job on the real sea. The experiments were carried out on the small stern trawler, and roll and pitch motion of the ship according to the wave directions were simultaneously recorded by P/C in the same sea conditions. From these data, the statistical properties and power spectra were obtained, and then the analysis of ship motion in trwal job was made. As a result, it was found that the pitch motions in trwal job were displayed low amplitudes on the whole, but the rolling motions were displayed high amplitudes relatively, and very high value on the beam and quartering sea especially. Also, the trial ship has a high extinction coefficient in the roll motion, compared with the rule of stability, but when wave height takes 2.5m over, it can induce the safety of ship to scare occasionally. Therefore, a usefull countermeasure for the safety of ship has to be made adequately.

The purpose of this study is to predict the roles of public social workers and clarify their job. There were a few studies concerning them, and they suggested that it was needed to reform the delivery system or to supplement personnel. But they were almost normative. This study, based on the literature, analyzed public social workers' daily works to suggest their desirable roles. Generally the job of public social workers consists of two functions. One is income maintenance function, the other is social services function concerned with economically disadvantaged. The result showed that these functions were meshed up to now. Especially, It also showed that although they performed mostly eligibility work related public assistance and general practices, they wanted to perform professional practices. Took into account their working conditions, it seemed to be desirable to clarify their job. Thus, several suggestions based on these results are as follows: First, while eligibility functions are the central aspects of the public social worker's roles, it is needed for them to provide selected access services. Second, if they wanted to perform social services, it would be needed to restrict their roles for case manager and broker.

Purpose: This study is designed to verify affecting variables to turnover intention of nurses in general hospital. Methods: The data were from the self-reported questionnaire responses of 168 nurses in five general hospitals 300-400 beds in Seoul and Gyungi province and analyzed by frequency and percentage, t-test, ANOVA and Sheffe's test and stepwise multiple regression. Results: The means of turnover intention were $3.14{\pm}0.87$, job overload, $3.54{\pm}0.67$, role ambiguity, $2.87{\pm}0.71$ and burnout, $2.68{\pm}0.72$. A significant correlation was found among turnover intention and job overload (r=.24, p<.001), role ambiguity (r=.30, p<.001), and burn out (r=.58, p<.001). The factors that affect turnover intention from the result of multiple regression by the stepwise selection, were emotional exhaustion, role ambiguity, and diminished personal accomplishment. Conclusion: Based on the results, to reduce turnover intention of nurses, emotional support should be provided and also range of roles be clearly defined. In addition, it is needed to improve the working conditions for nurses to get a sense of accomplishment.

Purpose: This study was designed to examine effects of sense of calling, job satisfaction and organizational commitment on retention intention in nurses who are at the advanced beginner-stage. Methods: Participants were 199 nurses with 13 to 36 months' clinical career at hospital located in Busan, Korea. Data were analyzed using descriptive statistics, independent t-test, one-way ANOVA, Scheffe test, Pearson correlation, and Multiple regression. Results: Retention intention correlated positively with sense of calling (r=.43, p<.001), job satisfaction (r=.31, p<.001) and organizational commitment (r=.31, p<.001). Factors affecting the participants' retention intention were found to be statistically significant (F=21.96, p<.001). Total factor score accounted for 24.1% of retention intention. Out of the related factors, the most influential factor was 'goals/meaning', belonging to the sub-areas of the sense of calling and explaining 18.2% of retention intention, followed by organizational commitment and average monthly income in that order. Conclusion: The results of this study suggest a need to develop a management program that helps promote retention intention for nurses at the advanced beginner-stage by both improving their monthly income and outside conditions and, more importantly, raising their sense of calling, especially in association with the goals/meaning of their life.

For the development of a new antidementia functional food or alternative drug using agricultural products, Job's tears (Coix lachrymajobi L.), which shows high acetylcholinesterase (AChE) inhibitory activity (55.1%) was selected and the extraction conditions of AChE inhibitor were optimized. AChE inhibitor of Job's tears was maximally extracted when it was treated with 60% methanol at $40^{\circ}C$ for 6 h. The AChE inhibitor of the methanol extracts was partially purified by systematic solvent extraction, thin layer chromatography, silica gel chromatography and reverse-phase HPLC and the partial purified AChE inhibitor with inhibitory activity ($IC_{50}$) of $0.608\;{\mu}g$ was obtained. The partial purified AChE inhibitor was soluble in methanol and hexane, and insoluble in water. Its maximum absorption spectra was 230 nm and also it was stable in the range of $30^{\circ}C$ and $70^{\circ}C$ and pH 4.0-8.0 for 1 h.

Human resource management has always been the most important part of any organization (corporate and government-owned). Until whenever improvement in human resource management is always the background of every problem that occurs in the organization. This study aims to examine the relationship of procedural justice and organizational commitment to OCB satisfaction and job satisfaction in the Public Works Office of Kutai Kartanegara Regency. Sampling involved the entire population, i.e. 109 informants. They are employees who have goods and services certificates. Hypothesis test carried out with the SEM-PLS model in two stages (outer model and inner model). After that, the survey data was used SMART PLS 3.0. Based on empirical findings, we find that procedural justice has a positive and significant effect on OCB, while organizational commitment does not. Procedural justice, organizational commitment, and OCB have had a positive and significant effect on job satisfaction. The novelty of the study lies in the originality value that describes the conditions in a government agency with different benchmarks (variables and indicators) from previous studies, so it is very interesting and varied.

Purpose: This study seeks to address the omission through examining the manner in which demographic similarity affects the responses of employees in the retail sector towards horizontal pay dispersion. Through doing so the study will be effective in bolstering the recent efforts of more careful exploration of conditions. Research design, data, and methodology: Scant past studies are available to guide for practitioners in retail sector which compensation strategy might lead adequate job performance for retail sales workers. To suggest possible solution, the present authors used variables of pay dispersion and obtained 317 US retail sale workers in distribution channels to measure the association between pay dispersion and employee job performance. Results: The statistical findings indicated both first and second hypothesis could be acceptable with favorable Beta and T values, resulting high degree of pay dispersion leads a low level of job performance, while a low degree of pay dispersion can motivate retail sales workers to improve their performance. Conclusions: The findings of this study raises an argument that processes of social comparison work in a more vigorous manner. This is thus a representation of the propensity of a retail sales worker to voluntarily resign from an organization when dispersion rates are higher.

A research tool was used questionnaire that was proved reliability and validity. It was prepared with totally 37 questions such as 12 items for subjects' general characteristics, 18 items for job satisfaction measurement, and 7 items for social support measurement. An analysis of the collected data was computationally processed by using SPSS Win 17.0 program. An analytical technique was made by using statistical techniques such as frequency & percentage, T-test or One-way ANOVA analysis. The following are the analytical results of the collected materials. Results: As a result of analyzing research subjects' job satisfaction level, there was significant difference(P<0.05) in items of religion, hobby life, working environment, and rest time out of daily work. The whole mean in job satisfaction was indicated to be relatively high with 3.13. However, job satisfaction with social recognition, salary, and safety was indicated lowly. As a result of analyzing research subjects' social support level, there was significant difference(P<0.05) in items of age, working environment, and rest time out of daily work. The whole mean in social support was indicated to be relatively high with 3.49. As a result of analyzing correlation between job satisfaction and social support, all variables were indicated to be positive correlation in high significance level, thereby having been indicated that the higher job satisfaction leads to the higher social support. Conclusion: As a result of this study, there is high correlation between social support and job satisfaction. An effort and a support are considered to be necessary for forming positive personal relations among members such as relationship with family member and with fellow employee, for improving the working conditions, and for enhancing dental technicians' pride and social recognition in order to promote dental technician's job satisfaction.

The purpose of this study is to demonstrate the effects of job training program satisfaction on objective training performance such as employment rate. In addition, the NCS(National Competency Standards) level was considered as a moderating variable in order to clarify the boundary conditions between job training program satisfaction and employment rate. The data used for the analysis of the research model are 513 job training programs that provide employment rate information among job training programs of 2016 Gwangju area on HRD-Net. The results of the analysis are summarized as follows. First, The satisfaction score of the job training programs calculated on the basis of the six dimensions of satisfaction is 4.46. The NCS level of the job training programs ranged from 2 to 6. The average score of the programs was 3.32. Second, satisfaction with the job training programs has no statistically significant effect on the employment rate, but the NCS level of the job training programs was found to be statistically significant in the interaction effect. Finally, policy implications, limitations, and further research directions are mentioned through this study.
