The purpose of this study was to compare the task elements categorized into required and additional man power's implemental between present and future-oriented duties of school nutrition teachers. The survey consisted of five duties, 27 tasks, 93 task elements, and 270 work details in the task elements of school nutrition teachers. A pilot-test was first conducted on nutrition teachers to confirm the survey contents, and then a main survey was performed on 240 school nutrition teachers, using a self-administrated online method, from July 16 to September 5, 2016. To compare present and future-oriented tasks, frequency analyses were conducted. Work details in the task elements were categorized into 'required' and 'additional man power's implemental', depending on school nutrition teachers' responses, based on a 50% cut-off percentage. The results showed that 13 work details among 60 work details (21.7%) in the 'Duty C. Safety and hygiene management of school foodservice', and 15 work details out of 106 work details (14.2%) in 'Duty B. Foodservice management practices' were identified as additional man power's implemental in future oriented duties. As to 'Duty A. Nutrition management', only three work details among 55 work details (5.5%) were identified as additional man power's implemental. On the other hand, all work details in 'Duty D. Nutrition diet education and counseling and 'Duty E. Reinforce professionalism' were identified as "required" as school nutrition teachers' duties. These findings imply that school nutrition teachers perceive nutrition management and education as their primary duties to the fulfill school foodservice' mission of promoting students' health and fostering students' dietary behaviors. The study offers practical and governmental implications, which can encourage school nutrition teachers to perform their primary duties.

Each municipality is promoting signboard improvement projects, but the effectiveness is not great. The main reason for this is that when the signboard is manufactured the location of the shop is only dependent on the visual aspiration effect and it is not harmonized with the building by applying uniform design. The signboard are installed almost everywhere in the city, such as residential, natural and commercial environments. And the signboard provides various services such as traffic information and life safety to customers. Also, by applying design and functional elements, we can enhance the competitiveness of companies and improve the urban environment by enhancing the mutual connection effect of customers and space. The purpose of this study is to investigate the effect of design elements and functional elements of the signboard on customer preference. In other words, we conducted surveys and analyzes of 152 specialists and non-experts (customers, self-employed). As a result of the study, the following conclusions were drawn. First, the functions and design elements of signboards are important factors that have a positive effect on customer preference. Second, the function of the signboard has a positive(+) influence on the customer preference, and the information providing function and the corporate image side function directly affect the customer preference. Third, color elements have a positive(+) meaningful effect on customer preference. Especially, similar color sign affects customer preference positively. Fourth, the signboard design component has a positive(+) significant effect on customer preference. In particular, typefaces have a positive effect on customer preference.

A data registry is a physical place to keep characteristics of classes of objects exist in the real world when they are chosen to record as data. It provides a centralized directory to describe the meaning, representation, and identification of data elements and their values. It assists to prevent redundancy and to preserve common understanding about the data described in a metadata set. In this paper, we investigate and classify various components of IBS(Intelligent Building Systems), specially HVAC in Building Automation Systems. We present IBSDR(Intelligent Building Systems Data Registry) model that specifies not only the detailed information on data elements but also the process of documenting data in IBS. It functions as the medium to create the data sharing environment to maintain exact meaning of data for every data elements so that database management designers or related users can create and exchange their DB without major modification. It also serves as a clearinghouse for information about IBS data. So all users can freely retrieve from and register data elements to IBSDR based on ISO/IEC 11179 through World Wide Web.

Recent climate change has led to fluctuations in agricultural production, and as a result national food supply has become an important strategic factor in economic policy. As such, in this study, panel data was collected to analyze the effects of seven meteorological elements and using the Lagrange multipliers method, the fixed-effects model for the production of five types of food crop and the seven meteorological elements were analyzed. Results showed that the key factors effecting increases in production of rice grains were average temperature, average relative humidity and average ground surface temperature, while wheat and barley were found to have positive correlations with average temperature and average humidity. The implications of this study are as follow. First, it was confirmed that the meteorological elements have profound effects on the production of food crops. Second, when compared to existing studies, the study was not limited to one food crop but encompassed all five types, and went beyond other studies that were limited to temperature and rainfall to include various meterological elements.
