We tested for residual pesticide levels in school foodservice agricultural products in Seoul, Korea from 2010 to 2012. A total of 316 samples of 23 different types of agricultural products were analyzed via gas chromatography-nitrogen phosphate detector (GC-NPD), an electron capture detector (GC-${\mu}ECD$), a mass spectrometry detector (GC-MSD), and a high performance liquid chromatography-ultraviolet detector (HPLC-UV). We used multi-analysis methods to analyze 185 different pesticide types. Among the selected agricultural products, residual pesticides were detected in 26 samples (8.2%), of which 6 samples (1.9%) exceeded the Korea Maximum Residue limits (MRLs). We detected pesticide residue in more than 65% of the Chwinamul, while 6 among 9 analyzed samples contained pesticide residue, and 1 sample exceeded the Korea MRLs. Among the 185 kinds of pesticides that we have tested, 18 were detected, while 7 of them were detected more than twice. Data obtained were then used for estimating the potential health risks associated with the exposures to these pesticides. The most critical commodity is carbofuran in the perilla leaves, which has contributed 3.8% to the hazard index (HI). These results showed that the detected pesticides could not be considered as a serious public health problem. Nevertheless, constant supervision is recommended.

The purpose of this study was to investigate a plan of middle/high school foodservice systems which could properly provide nutrition for juveniles' health. Questionnaires were developed and distributed to: 245 middle schools with 271 parents, 328 students, 180 teachers, and 345 administrators; 163 high-schools with 223 parents, 466 students, 179 teachers, and 163 administrators in Seoul and Kyunggi province. The results of this study were as followed. For the desirable feeding type as in-school meal plan, 62.2% responded to the current elementary school feeing type:10.3% responded to a lunch-box prepared at home; and 38.0% responded to free dining out type. For a feeding operation type, school administrators, teachers and parents favored the current school feeding systems in elementary schools with proportion of 68.2%, 47.7%, and 87.6% as respectively. Also, 20.3% of school administrators, 22.6% of teachers, and 6.9% of parents preferred contract management. A total of 27.6% of teachers, 9.2% of school administrators, and 3.7% of parents responded to a lunch-box prepared at home. There was a significant difference between the responses for establishing the main body of financial burden to solve the problem of financial burden which could be the most obstacle to bring middle/high school feeding system into operation. For the management of school feeding systems when brought into operation, 88.7% out of 470 responded schools and 89.9% out of 227 responded teachers reported that an expert should manage school feeding systems. For futuristic direction, an effective joint cooking type between schools which may be the way to solve the difficulties in securing the appropriate space and to decrease the financial burden, the problem of transportation for delivering feeding products, low quality of feeding, and sanitation can occur. Therefore, the distance between schools which operate a joint cooking system will affect as a major factor. Furthermore, concrete examination of plans for introduction of various types of school feeding and institutional devices for management system and supervision of operation should become a condition precedent.

Advances in medical technology and living standards have led to an age of aging. In addition, the development of technology and the popularization of computers have led to the development of the contents business and the release of several functional games. Among these functional games, silver functional games are being played to solve problems such as dementia, a major problem in the aging era. In this study, prior research was analyzed to suggest factors that help design based on the kinetic elements of the design method of the motion-based convergence game for the leisure use of the silver generation. Based on the analysis, the model of exercise factors for preventing dementia is presented. This research design a silver motion-based functional game using the anti-dementia exercise model presented in this study in the future, we expect to see an effective and efficient silver game in the long term.

This study conducted a survey to investigate career decision-making self-efficacy, and career preparation behavior related to self-leadership among students major in culinary area. Frequency analysis, factor analysis, reliability analysis and multiple regression analysis were employed using SPSS 16.0 Version statistical package program, and various results were discovered. First, all the subfactors of self-leadership factors (behavior focused, natural reward, and constructive thought strategy) had a positive effect on career decision-making self-efficacy factors (occupational information, goal setting, career planning, problem solving, self-appraisal). Second, all the factors of self-leadership factors (behavior focused, natural reward and constructive thought strategy) had a positive effect on career preparation (information search activity, goal achievement activity). As a result, the study confirmed that strengthening of self-leadership for culinary major college/university students is important predictor for development with career decision-making self-efficacy and career preparation behavior.

Gamification can be more fun and interesting than boring and it can be used for variety of educational subjects. Through the fun and flow of the learner, the learner understands the meaning and context of the problem to be solved. It will be able to collect, analyze and creatively solve data in a way that computers understand. Training through gamification will be an effective and memorable coding education for the efficient learning of coding education among the newly designated compulsory education. It is considered to be highly useful as a convergence study to increase tourism experience. Currently, in the field of school, coding education is mainly conducted using entry and scratch, which are educational programming languages, and coding education using gamification is not extensively used in the current education field. It is also expected to be used to increase the tourism experience, and it can be used to enhance the learner's computational thinking ability and creativity.
