Recently junior colleges in Korea have been working to meet changes in industrial and educational surroundings by establishing new departments, integrating and abolishing existing ones, or adjusting departmental quotas. These endeavors need to be based on analysis of industrial policies, both national and international, and of the industrial trend of the region in which the particular college is located. They also need to take into consideration change in educational policies and the direction of the college's specialization. This study aims to provide some foundation materials for these endeavors. As a result, it has considered changes in industrial and educational surroundings and analyzed the whole spectrum of departments existing at Korean junior colleges, with a focus on business-related ones. To summarize, each college offers departments, having taken into consideration its regional, industrial, and educational environments. The result of this study may be utilized by colleges when they establish new departments, integrate and abolish existing ones, and adjust departmental quotas.

This study suggests systematic procedures to improve safety policies on prevention of industrial accidents associated with industrial machines and devices. Specifically, new method of cause analysis of industrial accidents associated with industrial machines and devices is suggested and the related accident data are re-analyzed. Effectiveness of direct safety regulations such as safety certification, self-declaration of conformity, safety device regulation and safety inspection of industrial machines and devices are also analyzed. Based on those analysis results, transition from the current user-oriented safety device regulation to more balanced direct regulations on both manufacturer and user is suggested. Together with severity and frequency of industrial accidents, unit severity and unit frequency need to be taken into account to further assess the risk associated with a particular industrial machine or device. Balance between safety regulations will be realized by proper adjustment of lists of safety certification and inspection, and certification and inspection standards. This will also guarantee the maximum benefit over cost in such safety regulations.

Ritchken(1985) analyzes free replacement and pro-rata warranty policies for products receiving renewable warranies. He shows that for constant failure rates pro-rata warranty policies are more attractive to risk-averse manufacturers than shorter term free replacement policies that result in the same average warranty cost. This paper considers the case when product lifetimes distributions are of phase-type. When this is so, Ritchken's performance measures can be simplified considerably. It is found, that irrespective of the pattern of failure rates, pro-rata warranty policies are preferable to free replacement policies. But the warranty period of the equivalent free replacement policy decreases and then increases, as product reliability(the average time between failures) increases.

최근 서울대도시권 내 기업가정신의 공간분포에 관한 여러 연구가 있어 왔지만, 기업가 집적지들의 산업구성과 공간 분포 사이의 관계를 면밀히 살펴보지 못했다. 이에 본 연구는 2021년 벤처 캐피털 투자액 자료를 이용해 먼저 핫스팟 분석을 통해 기업가 집적지를 식별하였다. 이어서 집적지의 산업구성을 분석하기 위해 산업 다양성 및 전문화, 소프트웨어 및 비소프트웨어 산업 비중을 측정하였고, 집적지 조성 관련 정책도 검토하였다. 그 결과, 서울대도시권 내 14개의 기업가 집적지를 확인하였고, 도심에 인접한 집적지일수록 산업 다양성과 소프트웨어 산업 비중이 높으며, 정책이 교외 집적지의 산업 전문화에 크게 영향을 미치는 것을 확인하였다. 본 연구는 이러한 이해를 바탕으로 집적지 정책이 수립되어야 함을 시사한다.

There hardly have been support policies for small wholesale vendors or any materials such as proper statistical standards and figures compared to diversity of support policies and size of budget for small and medium manufacturing business. The biggest concern coming from it is that there have never been any policies for small and medium wholesale vendors. This study proposes some ways to improve support policies through investigating the current status of those vendors as their true values haven't been properly recognized, while diverse support systems have been devised for manufacturing business thanks to the traditional industrial development process. According to the study on support policies for domestic and international small and medium wholesale vendors, I realized that those vendors need a policy to ensure them to be promptly adjusted to the rapidly changing distribution environment and to be competitive to access to the global distribution market to finally become hidden champions through systematical operations of small and medium wholesale vendors and implementing educational business through sales management. Therefore, I propose five ways to improve support policies for small and medium wholesale vendors by considering social and economic value, systematizing small wholesalers and scaling small and medium wholesale vendors, reinforcing support for wholesalers, support policies for new online market opening and offline market opening.

본 연구는 우리나라 주식시장에서 2000년 2월에서 2007년 6월까지 유지하여온 시장조성제도가 유형별로 각각 코스닥 IPO 저평가에 미친 영향을 분석함으로써 가격지지제도의 실효성과 유형별 차이를 검증하고자 하였다. 또한 저평가에 미친 영향을 사전적인 효과와 사후적인 효과로 나누어 분석함으로써 시장 반응을 시기적으로 분류하고자 하였다. 분석결과, 시장조성제도는 공모가 저평가에 사전적 및 사후적 모두 IPO 저평가를 확대시키며, 사전적 효과가 사후적 효과보다 큰 것으로 나타났다. 또한 시장조성제도 중 시장조성의무제도와 풋백옵션제도의 제도별 차이분석에 있어 시장조성의무제도가 풋백옵션제도 보다 사전적 및 사후적 모두에 있어 저평가를 더욱 확대시키는 것으로 나타났다. 본 연구는 시장조성제도의 전 과정을 분석 대상으로 한 점과 시장조성제도에 의한 저평가 영향을 사전, 사후적인 효과로 나누어 분석한 점에서 선행연구들과 차별성을 가진다.

This study aims to suggest a measure to reduce industrial accident and secure adaptation to the industrial safety regulation policies by empirically establishing the effects of stress from adaptation to the industrial safety regulation on the human error, one of direct causes of industrial accident to the target groups of the industrial safety regulation policies. This study as for content range examines the stress from adaptation to the industrial safety regulation, job satisfaction, human error, and as for spatial range, this study performed an empirical research on the workers of 24 companies located within Chungcheong region centers district among 153 companies nationwide that uses 7 chemicals by introducing PSM (process safety management) system of the Ministry of Employment & Labor as of January 2012. Based on these results and suggestions there are five(5) necessities to reduce industrial safety regulations adaptation stress and human error generation, first(1st) is the necessity of understanding influential factors to stress, second(2nd) is the necessity to customized vocational training, third(3rd) is improving enhance system of job satisfaction, forth(4th) is preparing stress-reduction program, and fifth(5th) is introducing on-site restrictive action of advanced country as politics items.
