학교폭력에 대한 문제해결은 단시간 내에 이루어지기 어렵다. 학교폭력의 문제는 폭력에 직접 가담한 청소년들이나 학교, 부모들만의 책임이 아니다. 학교폭력 의 원인이 사회, 가정, 학교, 개인의 다각적인 요소가 결합되어 나타나는 것인 만큼 학교폭력의 예방도 가정, 학교, 지역사회의 협력 속에서 이루어져야 한다. 이 같은 점들을 감안해 본 연구는 학교폭력에 관한 설문조사 및 연구결과를 토대로 학교폭력의 발생요인과 학교폭력 예방을 위한 대처방안을 다음과 같이 제시한다. 학교폭력 예방은 단속과 처벌위주의 단편적인 접근보다는 선도와 예방을 중심으로 하는 교정프로그램의 개발과 보급이 선행되어야 하며 학교폭력 예방을 위한 법적・재정적 지원이 뒷받침되어야 한다. 또한 학교폭력의 심각성에 대한 인식제고를 위한 캠페인과 홍보활동 등을 지속적으로 전개해 나가야 한다. 학교폭력은 매우 다양한 문제들이 복합적으로 작용하고 있기 때문에 학교폭력 예방을 위해서는 가정, 학교, 정부기관과의 유기적인 협력체제가 절실히 필요하다.
The aim of this study was to investigate status of safety accidents of school foodservice cooks in Daegu and to analyze the factors affecting the occurrence of the accidents in order to seek effective ways for preventing safety accidents in school foodservice. The survey showed that the most frequent safety accidents were ‘bruises’, followed by ‘burns’, ‘contact with harmful substances such as disinfectants’, ‘fall-off ’ and ‘sprains’. The mental fatigue perception of the respondents was generally lower than the physical fatigue perception. The means of the perception levels of work intensity, cooking environment of the foodservice place, and safety-related behaviors, and consciousness were 3.15, 2.99, and 4.06 out of 5 points, respectively. In addition, the annual average of the number of participating in the accident prevention training per person was 17.34 times, that is, the respondents received the training at least once a month on average. A multiple regression analysis was conducted to investigate the variables affecting the occurrence of safety accidents that happened to foodservice cooks. It revealed that the work intensity perception and the cooking environment perception influenced the frequency of safety accidents.
The purpose of this study is to investigate paths of the effects of L2 motivational self system and self-efficacy on Korean EFL learners’ English ability.

The major results of the study are as follows: (1) Self-efficacy is correlated with all constructs of motivation. It has the highest correlation with ideal L2 self and the lowest correlation with ought-to L2 self; (2) self-efficacy has a direct effect on ideal L2 self and ought-to L2 self whereas it has direct and indirect effects on elementary students’ English proficiency; and (3) ought-to L2 self has a positive direct effect and L2 learning experience has a negative direct effect on elementary students’ English proficiency. However, ideal L2 self has no effect on elementary students’ English proficiency. At the end of the paper, pedagogical implications and suggestions are discussed.
The purpose of this study is to find and compare the differences in stress level, stressor, and coping style of high school students according to their personality traits. And to identify the personality traits contributing to stress reduction. The results of the study can be used as basic data for reducing the stress of adolescents to improve their academic achievement and maintain mental and physical stability. The questionnaire survey was conducted for 10 days from June 7 to June 16, 2017 for S high school students in Chungbuk Province. The study employed four measuring instruments as Ego-gram, Ok-gram, stressor scale, and stress coping type scale. Individual personality traits were classified into ego-states and ok-states in TA (Transactional Analysis). Stressors are classified into 5 categories (school life, home life, human relationship, myself, environment) and stress coping styles are classified into 4 categories (problem-focused coping, social-support coping, feeling-focused coping, hope-thinking coping) used in the previous studies. The collected data were analyzed using T-test, ANOVA, and multiple regression analysis. As a result, the stress level of high school students showed significant differences according to sex, year, grade, sleeping time, personality traits, and coping styles. Personality traits that contributed to the stress increase were NP, AC, ‘you positive’, ‘i negative’ and personality trait that contributes to stress reduction is ‘you negative.’ Therefore, we can judge that individual personality traits have significant effects on stress level, stressor, and coping style and need to find the effective stress management method suitable for individual personality traits using counseling, repetition training, self-suggestion etc.
The aims of this study was to investigate the satisfactions with school food service and its influencing factors for elementary and middle school parents. We surveyed parents regarding their concerns about food ingredients and dietary life, perceptions of free school food service, the necessity of food supply systems such as school food service centers, and the satisfaction about the quality and management of school food services.

This paper introduces good game design elements to consider for educational game. A suggested theory is applied on case study of educational history game development which was conducted by collaboration of game and education research experts. In the beginning of study, we seek for good game elements from the nature of play. We define and reorganize indigenous characteristic of play into two categories, Ludus and Paidia. Ludus is more oriented toward complex rule base game, and Paidia goes toward play attributes. We design and develop educational game based on suggested core design elements. At last, we observe how suggested good game design elements influences our educational game, addressing how to apply our design theory to the educational game development process.
This study was implemented to understand the motivation factors for 2nd grade schoolchildren that effect on their preference for the sweet taste. The subjects included were 118 children (59 boys and 59 girls) and 118 children's guardians, from one elementary school. Children participated in sweet preference test and questionnaire survey with researcher's guidance provided in the school. Children's guardians were asked to fill out the questionnaire via home-letters. The results were as follows: 59% of the children preferred the cocoa beverage with the highest concentration of sugar among five cocoa beverages (0%, 2.5%, 5%, 7.5%, and 10% of sucrose/milk volume). The variables consisted of affective attitude, cognitive attitude, self-efficacy, parenting style, and sweets frequency. According to the analysis, sweet preferences were correlated with children's affective attitude (r=-0.207, p<0.01), self-efficacy (r=-0.288, p<0.01), frequency of drinking carbonated beverage (r=0.272, p<0.01), preference for yogurt (r=0.184, p<0.05), and preference for sweet bread (r=0.226, p<0.05). These results indicated that children can be more affected by affective attitude than cognitive attitude, and self-efficacy can be an important motivation factor to control the eating behavior related to sweets. Therefore, nutrition educators need to focus on developing various methods related to increasing self-efficacy for encouraging and motivating healthy eating behavior in children.
This study was designed to develop a scale to measure primary school English teachers’ professionalism based on affective factors. The Swailes' (2003) scale was used to best reflect the local context where teachers in primary schools teach English to young learners. Three surveys were sent to a total of 1,008 primary school English teachers. Three different focus groups were used to refine the survey items in the modification process from the first to the third survey. The data were analyzed using exploratory factor and confirmatory factor analysis. These results showed the validity of fifteen items for investigating primary English teachers’ professionalism: four items related to 'professional commitment', three related to 'professional autonomy', three items related to professional belief in public service, three items to profession as referent, and two items to professional regulation. It is hoped that the scale items developed in this study can be used to identify the standard of professionalism of primary English teachers and provide policy makers or school decision makers with data that can be used to enhance professionalism within the community of primary English teachers.
