최석준, 김선호. 10㎞ 달리기가 시상하부-뇌하수체-성선 축 호르몬에 미치는 영향. 운동과학, 제11권 제1호, 165-175, 2002. 10㎞ 달리기가 시상하부-뇌하수체-성선 축 호르몬에 미치는 영향을 알아보기 위하여 장거리 발리기 선수 남(16명)·여(8명)선수 총 24명을 대상으로 10㎞를 5.35m/sec∼5.6m/sec의 속도로 달리도록 하여 운동전·후·회복기에 프로락틴(prolactin; PRL), 황체형성호르몬(luteinzing hormone; LH), 난포자극호르몬(follicle stimulating hormone; FSH), 에스트라디올(estradiol) 농도를 비교 분석한 결과, Prolactin 농도는 두 집단 모두 운동직후에 유의하게 증가(p<0.01)하다가 회복기에 점차적으로 안정시 수준으로 회복되는 경향을 보였으나 유의한 차이는 없었으며, 집단간 유의한 차이도 나타나지 않았다. LH 농도는 두 집단 모두 운동직후에 증가하다가 회복기에 안정시 수준으로 회복되는 경향을 보였으나 유의한 차이는 보이지 않았으며, 모든 채혈시점에서 여성운동군이 남성운동군에 비해 유의하게 높은 수치를 나타냈다(p<0.01). FSH 농도는 남성운동군에서는 운동과 함께 증가, 여성운동군에서는 감소하는 경향을 보이고 있으나 유의한 차이는 나타나지 않았으며, 집단간 유의한 차이도 나타나지 않았다. 또한, Estradiol 농도는 두 집단 모두 운동직후에 증가하다가 회복기에 감소하는 경향을 보였으나 여성운동군에서만 운동직후에 통계적으로 유의한 차이를 보였으며(p<0.01), 모든 채혈시점에서 여성운동군이 남성운동군에 비해 유의하게 높은 수치를 나타냈다(p<0.01). 즉, 이는 고도로 단련된 달리기 선수들도 10㎞ 달리기 운동 후에 정상적인 시상하부-뇌하수체-성선 축의 기능을 유지하고 있었음을 알 수 있었다. Choi, SJ,, Kim, S.H Effect of Hypothalamic-Pituitary-Gonadal-Axis on 10㎞ running. Exercise Science, 11(1): 165-175, 2002. The aim of this study was to investigate the change of the prolactin, LH, FSH, estradiol on 10㎞ running. Twenty-four young long distance runners, men groups(n=16) and women groups(n=6) participated in the study were trained with running over 20㎞s every day for 3 to 4 years. And the change of prolactin, LH, FSH, estradiol have been measured 3 times, before, immediately, and 30mins recovery period each after a 10㎞ running at 5.35m/sec∼5.65m/sec. Statistical techniques for data analysis were repeated measure ANOVA The result of this study was as following; 1. The concentration of prolactin was increased significantly after exercise immediately and it began to decrease at rest level after 30mins recovery of both men and women's groups. But no significant difference was found between two running groups in before, immediately, recovery period. 2. The concentration of LH was decreased at 30mins recovery after increasing at exercise immediately of both men and women's groups. But, the LH level was higher significantly in the wmen's group than in the men's group at befoore, immediately, recovery period. 3. The concentration of FSH was increased at men's group after running but decreased at women's group after running. But there was no significant difference between two groups. 4. The concentration of estradiol, both groups showed a case of increasing after running immediately after and decreasing at recovery period. But, there was significant difference after running immediately in women's group. Also, women's group was higher significantly than men's group at all the blood sampling time. These result identified that the HPGA function is normally maintained after long distance.

The purpose of this study was to investigate the incidence of exercise-related gastrointestinal (GI) symptoms among Taekwondo(T), Judo(J), Weight lifting(WL), and Wrestling(W) athletes. The research population consisted of 413 weight reduced athletes(T: male=110, female=48, J: male=50, female=54, WL: male=62, female=24, W: male=65). The prevalence GI symptoms administered by questionnaire. The questionnaire was designed with yes/no or single word answer and a graded scale for each of the following symptoms: diarrhea, abdominal pain, epigastric discomfort, epigastric pain, nausea, vomiting, and regurgitation related to training, rest or during race. The participants of the study were well trained and had over 4 years males, 3 years females of exercise experience. The results of this study were as following : 1. The prevalence of upper GI symptoms in male weight reduced athletes was T(46.9%), J(46.8%), W(39.4%), WL(19.3%), respectively. The prevalence of lower GI symptoms among weight reduce athletes, males T(55.5%), W(50.8%), J(45%), WL(27.4%), females T(72.2%), WL(68.8%), J(55.6%), respectively. 2. Male weight reduced athletes with a high incidence of GI symptoms interfering with exercise, required treatment for 7.3% epigastric discomfort(T), 6.2% epigastric pain (W), 6% epigastic pain(J), 6% regrugitation(J), respectively. Female weight reduced athletes with a high incidence of GI symptoms interfering with exercise, required treatment for 11.1% epigastric discomfort(J), 6.2% epigastric pain(T), 5.5% regurgitation(J), 5.5% epigastric pain(J), respectively. 3. Male weight reduced athletes with the onset of epigastric pain during rest occured in 57.6%(T), 50%(J), 77.8%(WL), 61.1^W), nausea during rest occured in 71.4(WL), 50%(W), abdominal pain during rest occured in 66.7%(J), 63%(T), diarrhea during rest occured in 67.6%(T), 61.5%(WL), 55%(W), Female weight reduced athletes with the onset of epigastric pain during rest occured in 71.4(J), 45.6%(T), nausea during rest occured in 75%(WL), vomiting 100%(WL), epigastric discomfort during rest occured in 66.7%(T) and WL), regurgitation during rest occrued in 57.1%(J), diarrhea during rest occured in 66.7%(WL), 61.5%(T). Gastrointestinal symptoms are more prevalent among weight reduced athletes during rest. These symptoms might be adversely affect performance and recovery during competition. Therefore further investigation in to the etiology and pathogenesis of GI disorders in weight reduce athletes is warranted.

정부 연구개발 보조금의 기업자체 R&D투자에 대한 효과 분석- 2000년 이후 국내기업 사례를 중심으로 -

최석준,김상신 한국기술혁신학회 2007 기술혁신학회지 Vol.10 No.4

This study attempts to empirically investigate the effects of government R&D subsidies on private firm's R&D investment in Korean industry. The R&D subsidy effect is defined as the average percentage change in firm's R&D expenditures between what was actually observed among firms that received a subsidy and what these firms would have spent had the subsidy not been received. To measure the effect we use Difference-in-Differences (DID) model which sign as to whether the relationship between government subsidies and private R&D investments is on stimulating or displacing private R&D expenditures. The differences between this study and previous studies are that we tries to measure the effect of Government R&D across various sized firm groups such as large, small & medium, and venture firms and we add one lag of the subsidy indicator in order to capture the effect of the subsidies on private R&D during 2 consecutive period. Empirically, a firm with government R&D subsidy increases its own R&D investment by 13.9%. Also on average, 1% of government R&D subsidy leads to 0.031% of private R&D increase. The main results of this study are as follows : First, Government R&D subsidies stimulate private firm's R&D expenditures. Second, Government R&D subsidies greatly increase (statistically significant) company financed R&D expenditures only for large firms but had no effect on the R&D expenditures of small & medium sized firms and venture firms. 이 논문은 2000년 이후 R&D분야의 정부 연구개발 직접보조금이 기업의 연구개발 투자를 진작 또는 대체 시키는지 여부 및 기업유형별 정부의 보조금 효과가 달라지는가에 대해 Difference- in-Differences (DID) 모형을 이용하여 실증적으로 분석하였다. 그 결과 정부의 연구개발 보조수혜는 기업 연구개발 투자를 평균적으로 13.9% 증가시키는 보완적 효과가 있는 것으로 나타났으며, 보조금의 액수가 1% 증가할 때 기업의 자체개발 연구비는 평균적으로 0.031% 증가하는 것으로 나타났다. 기업유형별로는 대기업의 경우 보다 강력한 보완효과가 나타났으나 벤처기업이나 중소기업의 경우는 정부보조금지원이 연구개발비 확대를 초래했다는 실증적 증거를 발견하지 못하였다.

최석준 한국디자인문화학회 2000 한국디자인문화학회지 Vol.6 No.1

본 연구에서는 사회전반에 영향을 미치고 있는 e-Business에서 디자인의 역할을 규명해 봄으로써 앞으로 e-Business에서 전개될 수 있는 디자인의 기회를 제안하고자 하였다. 디자인의 기회를 도출하기 위해서 디지털을 기반으로 한 인터넷의 등장 이후, 짧은 기간동안 변화의 변화를 거듭하며 기업의 주요 사업모델로 정착되고 있는 e-Business 환경을 이해하고 디자인 관점에서 해석하였으며, 디자인 영역에서 수행해왔던 역할을 조사하였다. e-Business 환경에 대한 분석의 결과, e-Business의 가장 주목되는 특징은 사업모델이 꾸준히 변화하고 있고, 그 변화가 크게 정착화, 확립 및 다시 통합화, 산업구조의 재편의 3단계로 나뉠 수 있다는 점이다. 따라서 변화의 단계마다 디자인에서도 디자인 전문영역의 모색, 전문화 강화, 기업관리의 시스템 공유화 추진, 디자인 영역 확대 등의 대처하는 자세를 파악할 수 있었으며, 이러한 분석 내용을 토대로 e-Business의 핵심이유에 비교하여 디자인의 기회 및 전개방향을 제안할 수 있었다. 본 연구는 e-Business을 다양하게 지원하고 있는 디자인을 디자인의 관점에서 해석하고 재정립한 것에 의의를 둘 수 있으며, 향후 디자인이 e-Business의 정확한 이해를 바탕으로 보다 체계적이고 적극적인 자세로 e-Business 분야에서 주도적인 역할을 할 것으로 기대한다. This study proposes design opportunities which can be applied to e-Business after this, as clarifying the role of design in e-Business which has an influence on world at large. This study, to derive design opportunities, focuses on understanding and interpreting the e-Business environment in a design of view. e-Business, which has been frequently changed for a short, period and established as main business model of corporations since digital technology-based internet appeared. As the result of the research, the most remarkable features of e-Business are continuous change of business model and classifying those changing into 3 steps; appearance, establishment, integration and industry transformation. Therefore, we found out design`s role; trying to find another professional domain, enhancing specialization, participating in data standardization and extending design domain every changing step. And on the basis of those we could also propose design opportunities and direction of design development by comparing to the main issue of e-Business. The meaning of this study could be found in the interpretation and reestablishment of design capability which supports e-Business by various methods in a design point of view. And we expect, through accurate comprehension of e-Business, design with systematic approach and positive attitude can play a leading part in e-Business.

특수목적 시설 민간투자사업 거버넌스 개선 방향 -영국 국립물리연구소 실패 사례 분석을 중심으로-

최석준,이지혜,Choi, Seok-Joon,Lee, Ji-Hae 한국건설관리학회 2011 한국건설관리학회 논문집 Vol.12 No.2

The PPPs(public private partnerships) which was introduced in the later part of the 1990s has grown since 2005, with the beginning of BTL(Build Transfer Lease) type which retrieves the investment by receiving the lease payment from the government. As application areas and scale of the PPPs have been further expanded, it is expected the demand on special purpose facilities will be increased. We do know only successful foreign practices of the PPPs but have rarely consider the failure cases. Therefore, this paper derives implications by analyzing the case of National physical laboratory project which is known as a typical failure case of UK's PFI. We find that from the perspective of governance, the reasons leading to the failure of business are an insufficient of technical rationality, unsettled social relationships and inefficient risk management. Based on the case study, this study shows how to improve management system for special purpose PPPs business in Korea. 1990년대 후반부터 우리나라에 도입된 민간투자사업은 2005년 이후 민간이 정부로부터 임대료를 받아 투자비를 회수하는 방식인 BTL(Build Transfer Lease)방식이 추가되면서 더욱 활성화되고 있다. 현재 민자사업 적용 영역이 더욱 확대되고 규모가 커짐에 따라 SOC시설 외의 다양한 특수시설에 대한 수요가 커질 것으로 예상된다. 그러나 우리나라에는 현재, 민자 사업을 추진해왔던 해외 여러 나라들의 성공 사례만 전해질 뿐 실패 사례에 대해서 고려해본적은 없다. 본 논문은 거버넌스 측면에서 영국의 특수시설 PFI(Private Finance Initiative)사업의 대표적 실패 사례로 알려진 국립물리연구소 문제 분석을 통해 우리나라에게 주는 시사점을 도출하고자 하였고 이 사업을 실패로 이끈 원인으로 기술적 합리성의 부족, 사회적 관계의 미구축, 위험 관리가 효과적으로 이루어지지 않았음을 지적하고 있다. 이러한 문제들을 점검하여 현재 특수 목적 시설 관련 우리나라 민자사업에 주는 시사점을 생각하고 앞으로의 개선 방향을 제시하고자 한다.
