This study investigated the current status of foodservice management and the importance and performance of foodservice management according to the level of knowledge of workers. A survey was conducted between February 2015 and March 2015 for 329 foodservice workers at Community Child Centers in Chungbuk Area. Of these respondents, the majority (78.4%) of them were females. Most of them were in their 40s (40.4%) or 50s (33.4%). If the respondent's correct answer rate of knowledge was 0~50% or 51~100%, the respondent was classified into a 'Low Group (LG, n=175)' or a 'High Group (HG, n=154)'. Among a total of 14 foodservice management questions, 6 items (personal hygiene: 1 item; food material: 2 items; and food processing: 3 items) had relatively higher performance scores for workers in HG than for workers in LG. As a result of Importance-Performance analysis, 'Use different knives and cutting boards for fish, meat, and vegetables' was a variable of high importance but low performance. It was found that improvement was most urgently needed. Results of this study can be used to derive important items for improving foodservice management and policy development for foodservice workers at Community Child Centers.

Purpose - The current paper not only investigates the intermediating process of the association between job insecurity and organizational performance, but also tries to find a factor which mitigates the negative influence of job insecurity. Design/methodology/approach - By conducting structural equation modeling(SEM) analysis with survey data from 351 employees, this study tried to identify the mediating effect of organizational trust, as well as the moderating influence of ethical leadership in the job insecurity-organizational trust link. This paper built hypotheses that job insecurity decreases the level of employee's organizational trust, then the level of the employee's organizational trust would influence organizational performance. In addition, ethical leadership would function as a buffering factor between the association between job insecurity and organizational trust. Findings - This paper found that job insecurity had a negative influence on employee's organizational trust, and the employee's organizational trust had a positive influence on organizational performance. The ethical leadership mitigated the negative impact of job insecurity on organizational trust. Research implications or Originality - By empirically delving into the importance of ethical leadership and organizational trust to increase organizational performance, this paper may provide top management and leaders in an organization with important insights that they should adequately monitor and manage the level of ethical leadership and organizational trust.

Purpose - The purpose of this study is to investigate the effect of corporate social responsibility (CSR) on firm performance in China, plus the moderating effects of advertising intensity and environmental pollution. Design/methodology/approach - We analyzed our dataset that consists of 188 public Chinese firms drawn from the Shanghai and Shenzhen exchanges during 2010-2020. Findings - Based on the stakeholder theory and signaling theory, we proposed the positive relationship between the CSR level and the firm performance. Further, we configured consumers and the government as major stakeholders in China, suggesting positive moderating effects of advertising intensity and environmental pollution, respectively. Research implications or originality - The results show that the CSR level increases the firm performance. The advertising intensity positively moderates the relationship between the CSR level and the firm performance, but there was no significant moderating effects of environmental pollution. The findings confirm the importance of consumers for the CSR stakeholders. While the Chinese government strongly reinforces environmental regulation, CSR itself does not seem to be the fine-aligned action prioritized for mitigating environmental pollution.

The purpose of this research was to find out the state of the nursing performance of the home care nurses in Seoul in order to provide the data for the practical work guide. The data were collected from fifty home care nurses working in 22 institutions located in Seoul. The research tool used for this research was modified and tested by Song Jong-Rye(1999) which was originally modified the standard tool of American Nurses Association (1998) and was partly supplement and adjusted for this research. The reliability of this tool was Cronbach's $\alpha$=.0982. The collected data were statistically processed using SAS for t-test, ANOVA. $Scheff\'{e}$ test. Among the surveyees, 50% have been working as a home care nurse more than three years and 74.0% of them were married. And 52% have B.S degree with certification of home care nurse from the certification program for Home Care Nurses affiliated at nursing schools. Half of the home care nursing organizations were based on the general hospitals, and most(78%) of the responsible senior personnels of those organizations were nurses. The following results are drawn from this research. 1) The level of nursing performance by the task sectors General performance level of home care nurses was relatively high in grade of 3.06 from total 4.00. Among the task sectors. the ethical field scored the highest points, and the next were nursing intervention, professional training, and data gathering, and the research sector scored the lowest point. 2) The level of nursing performance by general features of home care nurses Statistically relevant correlation between performance according to the duration of working experience as a nurse(p=0.8951) and performance according to the duration of working as home care nurse(p=0.2263) did not emerge. Also, performance by marriage status(p=0.2218), education(p=0.5733), and taking the certification program for home card nurse(p =0.1560) has no statistically meaningful correlation. 3) The level of nursing performance by the type of home care nursing organizations There exists a significant difference(p=0.002) between performances by the types of organizations. Most of the responsible senior personnels of the home care nursing organization were nurses. The level of nursing performance of the home care nursing organization under nurse management was relatively higher than that of home care nursing organizations led by medical doctors or non-medical professional, but this was not proved as statistically meaningful(p =0.3617). 4) The level of nursing performance by task sectors according to the characteristic of home care nursing service organization There exists a significant difference between nursing performances by task sectors according to the characteristics of home care nursing organization(p=0.002). In case of model research center of one College of Nursing, the nursing performance in the sectors of organization, theory, and data gathering were lower than that of in hospital based home care nursing service. And in case of local home care centers, performances in sectors of organization, theory, data gathering, nursing intervention. professional training, and research sectors were significantly low. Based on the obtained results, overall performance of home care nurses can be appraised as relatively good. Especially, performances in sectors of the nursing intervention, nursing plan. and data gathering including the in direct nursing were recorded high scores. From this, it can be concluded that high quality of nursing is relatively practicing for home patients at these days. Since the high quality of nursing for patients was directly related to the level of nursing performances of home care nurses, it is required to improve practical performance level of them by making constant evaluation and running continual education program and supplementing curriculum for the sectors with low scores.

Heights of a platform above the rail for the passenger train in the country are classified into two categories such as the low level (500mm; mainline) and the high level (1,135mm; metropolitan subway line) platforms. In order to operate similarly both a mainline railroad and a metropolitan subway line, as the requisite door safety system, it is necessary to develop the doorstep equipment of the rolling stock regardless of both the low and high level platforms. In this study, performance requirements of doorstep equipments used for two types of platforms are examined on the supposition that the train only for the low level platform could stop in the both low and high level platforms.

본 논문은 각성도 평가시 주관적 평가와 생리신호인 GSR과 자극에대한 반응시 간(RT)와의 관계 및 각성상태에 따른 human performance에 대하여 연구하였다. KSS level이 높을 수록 Nz와 RT가 증가 하였고, 특히 KSS level 5이하 에서는 RT 값이 0.8 초 미만으로 낮으며 KSS level 7 이상에서는 평균 1.6초 이상의 높은 값을 갖는다. 이 는 KSS level 7 이상부터는 저각성상태로 인하여 작업에 대하여 human performance가 급격하게 저하함을 나타낸다. 5단계의 KSS level 에대한 Nz를 구현하였으며 KSS level 5에 대한 평균 Nz는 약 1.4이었다. 따라서 생리 신호를 기준으로한 각성상태의 효과적인 제어를 위해서는 Nz 값이 1.4이하의 범위 내에서 이루어져야 함을 알 수 있었다.

The purpose of this study is to investigate the importance-performance analysis for country-of-origin labeling at restaurants. There is a growing concern over food safety as well as interest in the country-of-origin for food ingredients served at restaurants. In this study, the importance-performance analysis for the labeling of country-of-origin at restaurants, revealed that there were significant differences in all 12 attribute items, and the importance was scored higher than the performance in all items. Also, the importance-performance analysis for the attributes of the country-of-origin labeling showed that 'supportive government policies', 'system of controls for violation of the country-of-origin labeling', and 'penalty for violation of the country-of-origin labeling' are included in the second quadrant, which has a high level of importance but a low level of performance.
