We proposed the blocking channel to reduce the performance decrease using the low correlation with cyclic delay scheme in LED-ID system. LED-ID is based on the visible light to transmit the data. However, It is occurred the block channel by structure or environment of indoor for light of straightness. LED-ID system is degraded the performance by the block channel as loss of data, and burst error. To solve the block channel, the proposed system is overcome the burst error by low correlation among data, which is able to obtain the maximize time diversity gain to improve the performance of BER by cyclic delay scheme. The BER performance is evaluated by computer simulation according to channel parameter. The simulation results shows that proposed system gives much better performance than conventional system and constant cyclic delay scheme system.

The purpose of this study is to investigate the effect of organizational safety and health management activities on safety and health performance by using the results of safety activity level evaluation of public organizations. To this end, a research model was established by using three fields as independent variables among the four areas of the safety activity level evaluation index: safety and health system, safety and health activity plan, and safety and health activity level, and the safety and health activity performance field as a dependent variable. Correlation analysis and regression analysis between major variables were performed. As a result of the correlation analysis, the safety and health activity performance had a significant positive (+) correlation with all of the safety and health system, safety and health activity plan, and safety and health activity level. The safety and health system had a significant positive (+) correlation with the safety and health activity plan and safety and health activity level, and the safety and health activity plan had a significant positive (+) correlation with the safety and health activity level. And as a result of the regression analysis, it was found that the organization's safety and health system, safety and health activity plan, and safety and health activity level all had a significant positive (+) effect on safety and health activity performance.

This study was designed to investigate the correlation between perceived TQM performance and job satisfaction of dietitians. The objective of the study is to help the management of foodservice by providing a direction which will elevate perceived TQM performance of dietitians and presenting plans which will ensure effective foodservice management. The survey sample was dietitians (n = 308) who were charged with foodservice management. The questionnaires requested information about demographics self-perception of TQM importance and performance levels, and Job satisfaction. According to the TQM importance and performance analysis, the level of performance was typically high in TQM items recognized as important by dietitians and low in areas where the recognized level of importance was low. Analysis was conducted on the job satisfaction according to demographic characteristics. The level of satisfaction in terms of salary and promotion increased relatively for those working in the industries and those who were older, married, and full-time employees with longer careers. The lesser the number of working hours, the higher their satisfaction levels were. Canonical correlation analysis between TQM performance and job satisfaction indicated higher canonical correlation (canonical correlations coefficient: 0.59). In conclusion, TQM performance-job satisfaction showed higher canonical correlation. When information exchange via network is made possible and more external customer recognition is gained, it increases the level of job satisfaction. The above results suggest that further research on the scope of TQM performance is thoroughly needed and continual training is necessary for foodservice managers.

The purpose of this study is to empirically analyze factors which influence social and economic performance of social enterprises, and to examine the correlation of factors affecting social and economic performance. This study was conducted following the hypothesis that the organizational characteristics(organizational type, certification type, certification year, social service supply type, and external grants) of social enterprises affect social and economic performance, and that significant correlation exists between social and economic performance. This study collected the disclosure materials of 219 social enterprises certified between 2007- 2014 from the directory of the Korean Social Enterprise Promotion Agency. The study results are as follows: First, organizational characteristics affect social performance(i.e. jobs for the vulnerable classes). In addition, certification year and external grants had a positive effect on social performance. Second, the organizational characteristics affect the economic performance(i.e. sales), and certification year and external grants had a positive effect on economic performance. However, organizational type had a negative effect on the economic performance(i.e. sales). Third, analysis found a positive correlation of factors affecting social and economic performance. This study suggests the need to diversify support policies according to the number of authentication years in order to promote self-reliance and sustainability by maximizing the social and economic performance of social enterprises.

A few commonly used correlation equations of the enthalpy of vaporization are reviewed and a new three-parameter correlation equation is proposed. Performance of the pro­posed equation is examined using the data listed in the ASHRAE table for 22 pure substance refrigerants. The new equation yields an average absolute deviation of $0.14\%$ for 22 refrig­erants, which is better than those of other equations, such as Xiang $(0.18\%),$ Majer-Svoboda­Pick $(0.18\%),$ and Somayajulu equation $(0.23\%)$.
