There was a difference in recognition of respirators according to the educational performance environment. they were showed higher recognition of respirators of group by internal and external mix trainer, less than 6 months, over 1hour, more than 5 times, variety of education. To identify the relationship between types of job classification(typical and atypical)and the levels of recognition of respirators, a total of 153 workers in a business workplace. mainly, typical workers showed higher recognition of respirators than atypical workers. Training of correct wearing showed high demands both typical and atypical workers. Descriptive statistics(SAS ver 9.2)was performed. the results of recognition of respirators were analyzed the mean and standard deviation by t-test, and anova, fit factor is used geometric means(geometric standard deviation), paired t-test, Wilcoxon analysis(P=0.05). Particulate filtering facepiece respirators (PFFR) is one of the most widely used items of personal protective equipments, and a tight fit of the respirators on the wearers is critical for the protection effectiveness. In order to effectively protect the workers through the respirators, it is important to find and evaluate the ways that can be readily applicable at the workplace to improve the fit of the respirators. This study was designed to evaluate effects of mask style (cup or foldable type) and donning training on fit factors (FF) of the respirators, since these are available at various workplace, especially at small business workplace. A total of 40 study subjects, comprised of employment type workers in metalworking industries, were enrolled in this study. The FF were quantitatively measured before and after training related to the proper donning and use of cup or foldable-type respirators. The pass/fail criterion of FF was set at 100. After the donning training for the cup-type mask, fit test were increased by 769%. but foldable-type mask was also increased after the donning training, the GM of FF for the foldable-type mask and it's increase rate were smaller as compared to the cup-type mask. Furthermore, the differences of the increase rates of the GM of FF in employment type of the subjects were not significantly for the foldable-type mask. These results imply that the raining on the donning and use of PFFR can enhance the protection effectiveness of cup or foldable-type mask, and that the training effects for the foldable-type mask is less significant than that for the cup-type mask. Therefore, it is recommended that the donning training and fit tests should be conducted before the use of the PFFR, and listening to workers opinion regularly.

The purpose of this paper was to develop the key performance indicators of regional co-training programs, using analytic hierarchy process method. Firstly, we pooled indicators by reviewing the literatures. The researcher checked the properness and representative of them and then, the training professionals reviewed them again. Finally, we finalized the indicators, depending on the indicator domains such as MOU (Memorandum of Agreement) company (the training participation rate of MOU companies, training participation of employees, and etc.), training performance (the completion of the program, employment rate, and etc.), cost-effectiveness (training cost per capita), satisfaction (satisfaction rate of MOU companies and training participants), and regional co-training enhancement (the operation of the committee, the will for training of the regional municipal government, and etc.). The weight size varied by the regional training needs, satisfaction of MOU companies, and regional committees of human resource development. We also suggested the continuous revision of the key performance indicators for regional co-training.

The objective of this study is to investigate various jobs and foodservice environments, as well as work performances of school foodservice dietitians and nutrition teachers in accordance to the years of service in Daejeon and Chungnam provinces. A survey was conducted among school foodservice dietitians and nutrition teachers; a total of 415 from selected elementary, middle and high schools in the areas. In this study, we surveyed the participants and analyzed the current state of general characteristics, status of their job environments and foodservice environments by frequency, and the averages and differences in work performance with regard to 12 work parts and 57 works using one-way ANOVA and Duncan's multiple range test according to the years of service. Six parts among 12 work parts were significantly different in work performance according to the years of service. The 6 work parts were menu (nutrition) management, utensil recovery and management, sanitation management, foodservice administration & evaluation, dietary habit guide, and other works. The 11-15 years group ranked as the top on the total score and means of work performance. While the 16-years or more group, 6-10 years group, and under 5 years group followed consecutively. Correlation analysis between job or foodservice environments and work performances showed that work performances of school dietitians were mostly influenced by employment status, education level, and annual salary among the variables of job or foodservice environments. Other works, dietary habit guides and menu management were mostly influenced by variables of job and foodservice environments.

Corrugated steel plate shear wall (CSPSW) as an innovative lateral load resisting system provides various advantages in comparison with the flat steel plate shear wall, including remarkable in-plane and out-of-plane stiffnesses and stability, greater elastic shear buckling stress, increasing the amount of cumulative dissipated energy and maintaining efficiency even in large story drifts. Employment of low yield point (LYP) steel web plate in steel shear walls can dramatically improve their structural performance and prevent early stage instability of the panels. This paper presents a comprehensive structural performance assessment of corrugated low yield point steel plate shear walls having circular openings located in different positions. Accordingly, following experimental verification of CSPSW finite element models, several trapezoidally horizontal CSPSW (H-CSPSW) models having LYP steel web plates as well as circular openings (for ducts) perforated in various locations have been developed to explore their hysteresis behavior, cumulative dissipated energy, lateral stiffness, and ultimate strength under cyclic loading. Obtained results reveal that the rehabilitation of damaged steel shear walls using corrugated LYP steel web plate can enhance their structural performance. Furthermore, choosing a suitable location for the circular opening regarding the design purpose paves the way for the achievement of the shear wall's optimal performance.

Previous research has shown that steel plate shear walls (SPSWs) are efficient lateral force-resisting systems against both wind and seismic loads. A properly designed SPSW can have high initial stiffness, strength, and energy absorption capacity as well as superior ductility. SPSWs have been commonly designed with unstiffened and stiffened infill plates based on economical and performance considerations. Recent introduction and application of corrugated plates with advantageous structural features has motivated the researchers to consider the employment of such elements in stiffened SPSWs with the aim of lowering the high construction cost of such high-performing systems. On this basis, this paper presents results from a numerical investigation of the hysteretic performance of SPSWs with trapezoidally corrugated infill plates. Finite element cyclic analyses are conducted on a series of flat- and corrugated-web SPSWs to examine the effects of web-plate thickness, corrugation angle, and number of corrugation half-waves on the hysteretic performance of such structural systems. Results of the parametric studies are indicative of effectiveness of increasing of the three aforementioned web-plate geometrical and corrugation parameters in improving the cyclic response and energy absorption capacity of SPSWs with trapezoidally corrugated infill plates. Increasing of the web-plate thickness and number of corrugation half-waves are found to be the most and the least effective in adjusting the hysteretic performance of such promising lateral force-resisting systems, respectively. Findings of this study also show that optimal selection of the web-plate thickness, corrugation angle, and number of corrugation half-waves along with proper design of the boundary frame members can result in high stiffness, strength, and cyclic performances of such corrugated-web SPSWs.

Recently, many companies consider various methods for hiring employees. Hiring talent employee has made influences on the future of the company. Therefore, companies spend a lot of money for developing many tools on hiring employee. But most of companies don't try to review the comparison between the assessment system of hire and performance. There is few research on the performance results from the assessment scores of hiring. Only, the companies focus on hiring good employee who have good ability. Sometimes, HR managers are satisfied only with low quit rate. The paper analyzes what kind of relevance between the hire assessment and performance assessment for the same people. It uses the actual data for A company. This is very useful data for research on the relevance between hire and perform assessment. We can consider what the important things are for hiring and managing employee.

School dietitians are divided into two groups according to their status of employment, school nutrition teachers and dietitians, with the latter being irregularly employed by the institution. In this study, the job satisfaction, communication ability, work performance and importance in feeding services and dietetic counseling of both groups were compared. To accomplish this, 100 regularly employed school nutrition teachers (regularly employed) and 101 dietitians (irregularly employed) were surveyed by questionnaire. The results were as follows: (1) The irregularly employed dietitians showed a lower level of job satisfaction than the school nutrition teachers. This was likely because the school nutrition teachers belonged to the strong inner circle of school teachers and cafeteria workers, and had enough time to prepare for class lectures and consultancy. Conversely, the irregularly employed dietitians generally handle extra office work in addition to their primary duties. Despite these differences, both parties agreed that it was necessary to change the work system. Additionally, school dietitians reported that they had little opportunity for further training for career development. (2) Both parties had good communication skills; however, the irregularly employed dietitians had more conflicts with other staff members than the regular employees. (3) Job performance and job importance level was compared among employees involved in school feeding services and nutrition counseling. No significant differences were observed between dietitians and nutrition teachers in either group (p<0.05). However, the school nutrition teachers showed better skills than school dietitian with respect to public relations, running independent counseling offices, and using effective tools and materials. Job performance level was lower when compared to job importance level for all items, which meant the job was not well performed when compared to the work importance awareness.

This paper explores the impacts of ownership structure on performance of listed firms in China using 1994-2002 data. Using a new ownership classification scheme, this paper analyzes the impact of three factors, the ownership identity, equity ownership by the controlling shareholder, and equity ownership by the minority shareholders, on the performance of firms. Panel regression analysis shows that the firms controlled by the government are outperformed by firms controlled by private owners, supporting the hypothesis that the state pursues political objectives such as excess employment rather than profit maximization or the hypothesis that political interference by the Party or government may cause high political costs. Regression results also show that higher equity ownership by the controlling shareholder improves firm performance in private controlled firms and partially in marketized corporate controlled firms. The results also show that higher equity ownership by relatively large shareholders (from top 2 to top 10 shareholders) leads to better performance in marketized corporate controlled firms and partially in private controlled firms.
