The human resource management is a very important thing to an airline call center. It may lead the call center to success or fail. The call center managers have to make appropriate decisions how many persons are inputted into the operation for each unit time and all day. In this study, a method is suggested to get an optimal staffing for each unit time using Integer Programming. The Integer Programming model can be used to solve the efficiency problem of the call center's staffing and scheduling. And call certer manager can adopt this model into the operations of the call center without any difficulties or modifications.

The purpose of this study is suggesting the direction for improving web accessibility by analyzing the state of abiding by the web accessibility by the centers for teaching and learning support at the education offices in cities and provinces which provide the learning and teaching materials to the K-12 members and the interested people. For this aim, nine centers for teaching and learning support were evaluated. The primary manual evaluation by two experts and the evaluation by 18 users were conducted. The users were comprised of hearing-impaired people, visually-impaired people, brain-disabled people, the elderly, various browser users, and a variety of operating system users. As a result of the analysis, not a single center for teaching and learning support had conformed to web accessibility in the expert evaluation and the user evaluation. As a result of the expert evaluation, the errors regarding web design improvement, HTML source error correction, and provision of alternative measures for the disabled were found. This study is meaningful in the sense that it provided various discussions with regard to the direction of the future web accessibility evaluation based on the improved web accessibility evaluation method.

The purpose of this study was to understand the effect of job stress of female caregivers working in home-based elderly welfare centers on turnover intentions and to understand the moderating effect of self-elasticity in these relationships. The subject of the study was a self-written questionnaire survey of 170 nursing care workers at 28 home-based elderly welfare centers in Seoul, and 150 copies were collected and 133 people were finally analyzed excluding 17 unscrupulous responses. As a result of the study, first, the average value of turnover intention was high in the group with low experience of female caregivers at home-based elderly welfare centers and the group without religion. Second, the higher the job stress of nursing care workers, the higher the intention of turnover. Third, there was a moderating effect of self-elasticity between the job stress and the of turnover of nursing care workers. Therefore, it was necessary to consider measures to prevent job stress of nursing caregivers and improve self-resilience.

As the information technology is evolved and the human genome project is finalized over the world, the Bioinformatics - the integration of abundant Biological science and information technology - has shown up and is continuously being advanced. Together with the evolution of Bioinformatics, the websites dealing with Bioinformation have been set up to provide relevant information to the Bioscientists. Among the numerous global websites, the preferred websites by the majority of domestic Bioscientists are BRIC (Biological Research Information Center) of POSTECH(Pohang University of Science and Technology) in Korea, CCBB(Center for Computational Biology and Bioinformatics) of KISTI(Korea Institute of Science and Technology Information), KOBIC(Korean Bioinformation Center) of KRIBB(Korea Research Institute of Bioscience and Biotechnology), NCBI(National Center for Biotechnology Information) in USA, EBI(European Bioinformatics Institute) in Europe and DDBJ(DNA Data Bank of Japan) in Japan. In this paper, the comparative analysis was executed by investigating contents status and functions of the above-mentioned 6 websites. In addition, questionnaire survey of Bioscience Researchers' utilization status and their needs to those 6 websites was conducted.

Mathematical modeling is the process of representing physical phenomena using equations, and it often describes various scientific phenomena through differential equations. Numerical analysis, which is capable of approximating solutions to partial differential equations representing physical phenomena, is widely utilized. However, in high-dimensional or nonlinear systems, computational costs can substantially increase, leading to potential numerical instability or convergence issues. Recently, Physics-Informed Neural Networks (PINNs) have emerged as an alternative approach. A PINN leverages physical laws even with limited data to provide highly reliable predictive performance and can address the convergence issues and high computational costs associated with numerical analysis. This paper analyzes the weak signals, research trends, patent trends, and case studies of PINNs. On the basis of this analysis, it proposes directions for the development of PINN techniques in the agricultural field. In particular, the application of PINNs in agriculture is expected to be more effective than in other industries because of their ability to reflect real-time changes in biological processes. While the technology readiness level of PINNs remains low, the potential for model training with minimal data and real-time prediction capabilities suggests that PINNs could replace traditional numerical analysis models. It is anticipated that the research and industrial applications of PINN will develop at an increasing pace while focusing on addressing the complexity of mathematical models in agriculture, mathematical modeling and the application of various biological processes; securing key patents related to PINNs; and standardizing PINN technology in the field of agriculture.

This study aimed to evaluate the effectiveness of a foodservice and cooking program for children attending community child centers in Korea. The foodservice and cooking program included a reference menu, nutrition and hygiene class for foodservice managers, as well as cooking classes for children during the winter or summer vacation in 2015. In order to evaluate the program, a survey was conducted before and after the program. A total of 1,120 children who participated in the program completed questionnaires regarding eating behaviors, food intake, and their opinions and levels of satisfaction with the program. The scores of children's eating behaviors increased significantly from 59.71 to 63.62 out of 85 points (p<0.001). A significant increase was detected in children's food intake. Vegetable intake, which received the lowest scores, increased significantly from 3.63 to 3.81 out of 5 points (p<0.001). The score for opinions and satisfaction concerning the program was 28.34 out of 35 points. These results suggest that the foodservice and cooking program could be helpful in promoting healthy food habits in children attending community child centers.
