The research objective was to identify the effect of various instruction media on improving students' foodservice management competencies and for increasing class satisfaction. The research involved a comparison of two student groups. One group consisted of students who attended a lecture-based food purchasing class (Group A). The other group was students who attended the same class, and who also used various media as well as receiving the lecture (Group B). The results were as follows: 1) After a 16 week program, Group B perceived their procurement management competencies to be higher than those of Group A, especially in setting up purchasing goals, marketing research, and using computer systems for procurement; 2) In terms of class satisfaction, it was also observed that Group B was more satisfied with food purchasing class than was Group A. Group B gave high scores, especially in effective utilization of media, increasing motivation, and understanding; 3) Group B perceived that various instruction media was helpful for developing their procurement management competencies. Respondents evaluated the usefulness of media in the following order: using Power Point watching videos, visiting web-sites for food purchasing class, and surfing the World Wide Web. The results of the research show that using various instruction media for food purchasing classes would improve students' foodservice management competencies. Therefore, instructors who teach foodservice management related courses should consider developing teaching strategies that apply various instruction media for students to enhance their foodservice management competencies and to increase class satisfaction.

This study introduces the peer class consulting program at K-Institute of Technology aimed at improving class quality through the diagnosis of professors' teaching methods, analysis of the pros and cons, and assessment of their class management ability. To carry out the program, 641 students taking classes with the professors were surveyed on their satisfaction and learning motivation levels. The class composition was analyzed by monitoring the professor's class. The effect of the consulting was verified by comparing students' class satisfaction scores before and after consulting. Additionally, 29 professors subject to the consulting were surveyed on their satisfaction with the program. According to the results, professors subject to the consulting recognized that the teaching methods and class management strategies presented through the consulting effectively improved student satisfaction and motivation and provided an opportunity to gain confidence through the class. Furthermore, professors subject to the consulting were able to acquire knowledge, skills, and attitudes related to class management, and they perceived the program positively, stating that it allowed them to quickly adapt to the university education environment through cooperative communication with senior professors serving as consultants.

It is the concept of this paper to build up the convergence type of the total class service system, and the goal is to develop the education services, which are differentiated from existing digital textbooks and development tools. We establish developmental programs and convergence strategies from market analyses related to apps and digital education. Then this paper proposes 'E-Class Author Service System (ECA)' as an education service system based on the tablet PC. It is the convergence system of the app type of textbook development tool and class management system. Teachers can produce and develop class materials and textbooks using the app type of textbook development tool in ECA service system. They can also add necessary functions from the class management system for efficient class progress. ECA improves the interaction and communication between a teacher, student and parents in the sever-based network. This study expects that ECA will achieve prior occupation of the app market as an educational app development tool and reduce private education expenses.

Yield prediction is important to manage semiconductor quality. Many researches with machine learning algorithms such as SVM (support vector machine) are conducted to predict yield precisely. However, yield prediction using SVM is hard because extremely imbalanced and big data are generated by final test procedure in semiconductor manufacturing process. Using SVM algorithm with imbalanced data sometimes cause unnecessary support vectors from major class because of unselected support vectors from minor class. So, decision boundary at target class can be overwhelmed by effect of observations in major class. For this reason, we propose a under-sampling method with minor class based SVM (MCSVM) which overcomes the limitations of ordinary SVM algorithm. MCSVM constructs the model that fixes some of data from minor class as support vectors, and they can be good samples representing the nature of target class. Several experimental studies with using the data sets from UCI and real manufacturing process represent that our proposed method performs better than existing sampling methods.

Objectives : This study aimed to examine to relevance of socioeconomic class recognition and subjective health status of injured workers. Methods : We used data collected over 3years by the Panel Study of Worker's Compensation Insurance(PSWCI; 2015). Data was analyzed using the chi-square test and logistic regression using SPSS ver. 22.0 to verify the relevance between the socioeconomic class recognition and general characteristics of injured workers. Results : First, the income groups of first class, second class and third class were analyzed as being of lower socioeconomic class status, and the income group four class and five class was analyzed as being the middle-ower the socioeconomic class status. Second, the better the subjective health status, higher the perception of socioeconomic class status, as analyzed by Model 1 using only the parameters of socioeconomic status recognition and Model 2 and Model 3 using income class and general characteristics. Conclusions : Health and industrial accident policies are needed to improve awareness of socioeconomic class status of injured workers.

Development of information and communication technologies has given a lot of changes in the business processing methods including the school and class managements. However, many business processing systems are still based on desktop computer. In particular, most of the class management system only supports desktop computers; hence school teachers have difficulty in using their class managements systems on mobile environment. In this paper, we proposed and developed a mobile classroom management system for teachers, which will easily handle information such as personal records of students, student counseling records, student life record and so on. The implementation of the application of mobile-based class management can be managed by many school elements including student register information, student evaluation records and transcripts, counseling report, and so on.

Service Level Agreement (SLA) is a service providing scheme by a service class agreement between a user and a service provider SLA allows that a user can select an expected service class in various service classes provided from a service provider. Recently, SLA management is adapted to support the end-to-end Qos for service users in Beyond 3 Generation (B3G) networks. In B3G networks, SLA provides multiple service classes on access networks so that service classes should be managed to assure the service satisfaction for users. In this paper, we propose a dynamic Qos management scheme by IP traffic class controlling based on SLA in B3G networks. Also, to manage dynamic traffic service, we consider Differentiated services (Diffserv) mechanism for the resource management by SLA. An If service traffic class on SLA can be dynamically changed by Diffserv traffic management to support dynamic end-to-end Qos. Hence, in this paper, we consider the buffer threshold scheme for controlling traffic loads and the traffic level control scheme for implementing the dynamic traffic management by the SLA.

This study investigated the appearance management aspects of middle-aged male CEO's based on Bourdieu's class theory. We conducted in-depth interviews with male CEOs in their 40s and 50s to understand the characteristics of appearance management in terms of economic, cultural and social capital. We found that they acquire educational capital based on their parents' economic capital and form their own cultural capital as adults. They had the characteristics of Petit Brujois, which aimed for a higher class. The characteristics of differentiation based on appearance management identified three results came from solidifying one's class position: clothing management, diversifying and upgrading appearance management, and pursuing their own ideal image. The influence of social network and cultural capital was also observed in appearance management. This study explored the characteristics of discriminatory appearance management through an in-depth study of middle-aged male CEOs as well as contributed to understanding the context of capital and appearance management by applying Bourdieu's class theory. In addition, this study provides basic data that can be referred to a design and marketing direction for the men's clothing market by providing information on male consumers with high purchasing power.
