In the external inspection and packaging stages of products used in the semiconductor manufacturing process, there is a problem in which particles are adsorbed to the product itself or a carrying tool due to electrostatic discharge. This study presents a methodology that can improve the problem of adsorption of particles to a product by using a practical TRIZ technique. By applying the proposed practical TRIZ-based methodology, the problem was defined, and contradictions caused by product waiting time were derived. Among the derived contradictions, physical contradictions were set and the concept of ‘space separation’ was applied to derive solutions such as ‘installation of Ionizer’ and ‘improvement of the layout of the workroom’. As a result of the experiment by applying ‘Ionizer Installation’ and ‘Workroom Layout Improvement’ derived through the application of practical TRIZ, it was confirmed that the particle adsorption problem that occurs during the waiting time of the product can be solved. Through this study, it is expected that workers, facility engineers, and technical engineers working at manufacturing processes will be able to effectively solve the problems they face through creative thinking and change of ideas by using practical TRIZ techniques, and contribute to innovative technology development and productivity improvement.

청소년의 차별피해경험이 차별가해경험에 미치는 영향

정규형(Jeong Kyu-hyoung) 한국아동복지학회 2016 한국아동복지학 Vol.- No.55

본 연구는 청소년의 차별피해경험이 차별가해경험에 미치는 영향을 살펴보고 인권교육(빈도, 도움정도)의 조절효과를 검증하는데 목적이 있다. 연구에서 활용한 자료는 한국청소년정책연구원의 2014 아동·청소년 인권실태 조사이며, 중·고등학생 총 4,023명을 최종 연구대상으로 추출하였다. 본 연구는 SPSS PROCESS macro을 활용하여 조절모형을 분석하였다. 분석 결과 첫째, 중학생과 고등학생 간에 차별피해경험과 인권교육 빈도, 인권교육 도움정도는 통계적으로 유의미하게 차이 났다. 둘째, 청소년의 차별피해경험과 인권교육 도움정도는 차별가해경험에 유의미하게 영향을 미쳤으나, 인권교육 빈도는 영향을 주지 못했다. 셋째, 인권교육 도움정도는 차별피해경험과 차별가해경험 간의 관계를 조절하는 것으로 검증되었으나, 인권교육 도움정도가 낮을 때보다 높을 때, 차별피해경험이 차별가해경험에 미치는 영향을 더 높이는 것으로 나타났다. 이에 본 연구는 분석결과를 바탕으로 청소년 차별에 대한 이론적 논의를 이끌어내고, 인권교육의 나아가야할 방향에 대해서 실천적 함의를 제시하는 데 의의가 있다. This study investigated the impact of the experience of being discriminated on their actual experience of discrimination, and verified the moderating effect of the education for human rights. The data used in this study were sampled from the 2014 children and youth human rights survey of Korea National Youth Policy Institute, and 4,023 students in middle or high school were selected for the final data analysis. The moderation model was analyzed by applying SPSS PROCESS macro. The analysis suggested the following. First, it was shown that the experience of being discriminated and the level of help and frequency of the education for human rights were significantly distinguished in the statistics. Second, even though the experience of being discriminated and the level of help of the education for human rights meaningfully influenced the experience of discrimination, frequency of education did not. Third, it was verified that the level of help from education of human rights moderates the relationship between the experience of discrimination and the experience of being discriminated. It also showed that the higher the level of help is, the more the experience of being discriminated exerts influence on the experience of discrimination. Thus, on the basis of the results, the theoretical discussion on the youth discrimination was drawn out and the practical implication on the direction of the education for human rights was suggested.

The purpose of this study is to verify the mediation effect of aggression from abuse recognizing children``s cyber delinquency. The study uses multivariate latent growth models ranging second-year data to fourth-year data from ‘Korean Children and Youth Panel Survey’ 2011~2013(KCYPS). The findings are presented as follows. First, children``s average recognition rate of abuse, aggression, and cyber-delinquency decreases as children get older. It indicates that for three years-extending from second-year of middle school to first year of high school-recognition rate of abuse, aggression, and cyber-delinquency reduces as they grow older. Second, it is shown that the higher the initial value of abuse, aggression, and the cyber delinquency is, the smaller rate of change is. Third, research shows that child abuse indirectly influences cyber delinquency and the rate of change of cyber delinquency through the aggression. From these findings, social work interventions on preventing child abuse, reducing the cyber delinquency from adolescence, and lowering their aggression are suggested.

홍산문화 우하량 유적을 통해 본 『삼국유사』 「고조선조」의 神市

정규철(Kyu-Cheol Jeong) 바른역사학술원 2024 역사와융합 Vol.- No.19

홍산문화는 서기전 4700~서기전 3000년경까지 요서지역에서 발달한 신석기문화로 황하문명과 구별되는 독자적인 문명으로 한국사의 근원으로 연구되고 있다. 중국 학계에서는 우하량 유적이 조성되던 시기의 사회단계를‘이미 복잡사회를 이루어 고국古國 단계에 진입했다’고 보고 황하문명과 더불어 중국문화을 형성한 핵심문화로 여기고 있다. 홍산문화 유적이 중국 황하 중심의 전통 역사 인식과 구별되는 지리적 위치와 유물의 성격 등이 확인되었음에도 그 주인공에 대해 국내 학계 대다수는 한국사와의 관련성에 회의적이다. 홍산문화에서 새, 곰, 여신상이 동시에 드러난 우하량 유적군은 『삼국유사』「고조선조」의 환웅과 웅녀에 대한 기록을 증명해 주는 고고학 물증이다. 「고조선조」가 전하는 환웅 사화의 내용과 홍산문화 유적· 유물이 분명하게 정합하는 이상 고조선에 앞선 환웅의 신시 건국을 진지하게들여다볼 필요가 있다. The Hongshan culture is a Neolithic culture which developed in the Liaoxi region (the west part of Liaoning province) from 4700 BCE to 3000 BCE. It has been studied as the source of Korean history from an early age as it is a distinct civilization, independent from the Yellow River civilization. Chinese scholars consider the social stage at the time of the Niuheliang's site to be ‘already a complex society and entering the stage of early State’ and consider it a core culture that formed the Chinese culture alongside the Yellow River Civilization. Despite the geographical location and nature of the artifacts that distinguish the Hongshan culture from traditional historical perceptions centered on China's Yellow River, the majority of Korean scholars are skeptical of its relevance to Korean history. The Niuheliang's site group, where birds, bears, and goddess statues were simultaneously revealed in the Hongshan culture, is an archaeological evidence that proves the records about Hwanung and Ungnyeo found in the section about Gojoseon (ancient Joseon) in Samguk yusa. The story of Hwanung handed down by the Gojoseon Dynasty and the ruins and relics of Hongshan culture clearly fit together, we must study Hwanung's founding of Shinsi more seriously.

This study aims to analyze the influence of network of elderly with his or her non cohabiting children on their depression and its regional differences between urban and rural areas. The analysis is based on the sample of 1,609 elderly of 65 and above (1,011 Urban residents and 598 Rural residents) from the third time span(year 2010) to the fifth time span(year 2014) collected by the Korean Longitudinal Study of Ageing, whose research conducted by Korea Employment Information Service. First, it is found that rural elderly are more likely to suffer from depression than urban elderly. Second, it is found that rural elderly have on average a bigger number of non cohabiting children in their network, whereas geographical proximity and frequency in meeting, and economic support is stronger upon urban elderly. Third, urban elderly tend to suffer from depression as the frequency of phone calls with their non cohabiting children increases with time, and as the frequency of meeting and relationship satisfaction is decreases with time, whereas rural elderly tend to suffer from depression as their geographical proximity with their non cohabiting children is decreases with time. Based on the results of this analysis, this study further suggests practical policy interventions to prevent elderly depression.

정규만(Kyu man Jeong) 한국컴퓨터게임학회 2013 한국컴퓨터게임학회논문지 Vol.26 No.4

Digital dementia becomes an issue these days which causes failure of one’s memory and calculation ability because many people rely heavily on digital devices, such as smart phones. Smart devices themselves become smarter and smarter whereas digital device users become dumber and dumber, and finally they are suffering from digital dementia. Serious games can be defined as games which combine entertainments with various applications. They relieve the negative opinions which belong to existing games, so many game titles have been released as serious games in these days. This research is motivated by the fact that serious games were originated to overcome practical issues. In this paper, a serious game is presented to prevent digital dementia and its effectiveness is shown. The proposed serious game is composed of simple four fundamental arithmetic operations which improve one’s calculation ability. Since simple arithmetic operations are familiar regardless of one’s age, they are chosen. Everyone can enjoy the game beause random factors are added. This paper concludes that serious games can be used to prevent digital dementia very effectively.

정규형(Jeong, Kyu-Hyoung) 한국지방정부학회 2019 지방정부연구 Vol.23 No.1

The purpose of this study is to analyze the elderly suicide rate of each local government through a longitudinal approach so as to deduce multiple types of variations, and to identify factors that determine the deduced variation types in the elderly suicide rates in light of social capital factor. For this purpose, 251 cities, counties, and districts, for which the elderly suicide rates from 2010 to 2016 can be estimated, were analyzed as the subject matters of this study by utilizing the Causes of Death Statistics of the Statistics Korea. The analysis provided that, first, the elderly suicide rates over the course of time between 2010 and 2016 exhibited the classification of three variation types, which consist of the medium-level stable type, the high-level stable type, and the declining type. Second, the factors that determine the variation types in the elderly suicide rates have been found to include the ratio of the social welfare budget, the effective period of the Suicide Prevention Ordinance, the period in which pesticide safety boxes had been installed, and the social participation rates of senior citizens. Based on these results, this study proposed measures for the local governments to prevent the suicide of elderly population. 본 연구는 각 지자체의 노인자살률을 종단적으로 분석하여 다수의 변화유형을 추정하고, 추정된 노인자살률 변화유형을 결정하는 요인이 무엇인지 사회자본을 통해서 파악하는데 목적이 있다. 이를 위해 통계청의 사망원인통계를 활용하여 2010년부터 2016년까지의 노인자살률을 추정할 수 있는 251개 시군구를 연구대상으로 분석하였다. 분석 결과 첫째, 2010년부터 2016년까지 시간의 흐름에 따른 노인자살률은 총 세 가지 변화유형(중수준 유지형, 고수준 유지형, 감소형)으로 구분되었다. 둘째, 노인자살률의 변화유형을 결정하는 요인은 사회복지예산비율, 자살 예방조례 제정기간, 농약안전보관함 설치기간, 노인사회참여율 변화정도인 것으로 확인되었다. 이러한 결과를 바탕으로 지자체의 노인자살예방을 위한 개입 방안을 제시하였다.

정규형(Jeong Kyu-hyoung),김희주(Kim Hee-ju) 한국아동복지학회 2016 한국아동복지학 Vol.- No.56

본 연구는 청소년이 인지한 부모 감독 · 애정과 청소년의 오프라인 · 온라인 비행과의 관계에 대해 한부모가정과 양부모가정을 비교하였다. 한국청소년정책연구원에서 실시한 한국아동 · 청소년패널조사의 제4차~5차 데이터를 활용하여 고등학교 1학년,2학년 학생 총 1,812명(양부모가정: 1,628명, 한부모가정: 184명)을 대상으로 최종 분석하였다. 변수간의 관계를 파악을 위해 구조방정식모형을 활용하였으며,이 관계가 가정구조 별로 차이가 있는지 확인하기 위해 다중집단 분석을 진행하였다. 그 결과 첫째 부모의 감독은 양부모 가정에서만 청소년 오프라인 비행에 영향을 주는 것으로 나타났고,부모와의 애정은 양부모와 한부모가정 모두 오프라인 비행에 영향을 주지 못하였다. 둘째 부모와의 애정은 한부모가정에서만 온라인 비행에 영향을 주는 것으로 나타났고,그 경로 또한 양부모 가정보다 더 크게 부적으로 영향을 미쳤다. 부모 감독의 경우 모든 가정 구조에서 온라인 비행에 영향을 주지는 못하였으나, 한부모가정보다 양부모가정에서 더 크게 부적 영향을 미치는 것으로 나타났다. 분석결과를 바탕으로 청소년비행에 대한 보다 구체적인 사회복지적 실천적, 정책적 방안을 제시하였다. The purpose of this study was to compare between two-parent and single-parent families the relationship between perceived parental monitoring/affection and adolescent offline/online delinquency, we analyzed 1,812 cases of high school students (1,628 cases of two-parent families and 184 cases of single-parent families) using the 4 -and 5 -year data from the `Korean Children and Youth Panel Survey`. We used structural equation modeling to understand the correlation between variables, and conducted multi-group analysis to confirm the distinction between family structures. The results of the study were as follows. First, perceived parental monitoring influenced offline adolescent delinquency only among two parent families, while perceived parental affection did not influence either family type. Second, perceived parental affection influenced online adolescent delinquency only among single-parent families, and the path also had a greater negative effect than two-parent families. In the case of perceived parental monitoring, it did not influence online adolescent delinquency regardless of family type, but the path had a greater negative effect on two-parent families than single-parent families. Based on these results-, mare concrete social-welfare practical and political implications about adolescent delinquency propped.
