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.

This paper studies the fiscal issues with regard to BTL (Build Transfer Lease) scheme projects, a newly introduced type of PPPs (Public Private Partnerships) in 2005 and tries to provide some policy options. More specifically, we make suggestions to work out the issues such as how to account for BTL transactions and whether to introduce annual budget ceiling system for BTL payment, while we introduce and analyze the experiences of some other advanced countries and international institutes. 본 연구는 2005년부터 새롭게 도입된 임대형 민간투자사업(Build Transfer Lease: BTL)이 국가재정에 미치는 영향을 살펴보고 이와 관련하여 정부가 검토해야 될 정책대안을 모색하였다. 보다 구체적으로는 BTL 사업의 국가부채 인정 문제 및 예산운영준칙의 수립방안 도출을 위해 주요 선진국 및 국제기구에서의 제도와 동향을 살펴보고 우리나라에 적용할 수 있는 대안을 제시하였다.

The results of the experiment which has done for looking into the changes of muscle contraction characteristics after four-week endurance training in soleus muscle that has high ratio of slow-twitch muscle and medial gastrocnemius that has high ratio of fast-twitch muscle are as follows; 1. In case of the change of weight increase, both control group and experimental group showed similar increasing width till the third week. But when they were in the fourth week, the weight increase of experimental group slowed down, and had no influence on the muscle weight in general. 2. In case of the contraction characteristics of soleus muscle, there were no changes in the contraction time and the half relaxtion time. But twitch tension, tetanic tension, and fatigue index of experimental group showed the increase of 47%(p<0.01), 25%(p<0.05), and 12%(p<0.05) respectively. 3. In case of the contraction characteristics of medial gastrocnemius, there were no changes in the contraction time and the half relaxtion time. And experimental group showed improvements on the twitch tension and tetanic tension. The results mentioned above present such possibilities that the contraction time and the half relaxtion time, which are contraction speed factors of muscles, had no influence on show-twitch muscle and fast-twitch muscle, and that the twitch tension and the tetanic tension, which are contraction factors, could be influenced by the endurance training even in fast-twitch muscle. Henceforth continuous studies should be performed with the plans of various training periods and intensities.

Eye movement and neck muscle activities during Golf swing was studied in 6 male Golfers who were working at Pal Bong country club. Electromygraphic activities and eye movements were recorded by telemetry system. The following results were obtained : 1. Right neck muscle activities were increased at back swing Phase and left ones increased at impact follow through Phase. 2. Eye movements directed toward right side at down swing Phase and toward left side at recovery Phase. 3. Frequency of nystagmus was greater in darkness than in light. The results may suggest that the eye movement has a major role in the control of posture, also the analysis of eye movement is a significant physiological indicator for evaluate Golf motion.

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.

Gastrointestinal(GI) symptoms, epigastric pain, heartbum, nausea, vomiting, abdominal pain, and diarrhea are not uncommon in long distance runners and some cases of gastrointestinal mucosa of long distance runners. We prospectively studied endoscopic changes of gastrointestinal mucosa, to identify GI blood loss, and evaluated anemia before and after race in long distance runners. Sixteen male long distance runners(age:18.2±1.5), 200km running during a week and three running competition 3 months apart in 1 year participated in out study. All participants completed a symptom questionaire, stool Heme occult test(LA Hemochaser??, MIZUHO, Japan) and anemia study(Heomoglobin, Hb; hematocrit, Hct; serum iron, ferritin, total iron binding capacity, TIBC) 7 days before and immediately after running. The upper gestronistinal endoscopy examination was done before 10km competitive running. Thereafter runners with Heme occult positive stool specimens before and after race were asked to have a colonoscopy. Abdominal pain(n=9), diarrhea(n=8), epigastric discomfort(n=7), epigastric pain(n=6), nausea(n=6), regurgitation(n=4), vomiting(n=1) were noted during training, before, or follwing running. Erosive gastritis(n=11), reflux esophagitis(n=6), pangastric hyperemia with bile stained mucosa(n=5), gastric ulcer(n=1) were noted by upper gastrointestinal endoscopy. Four of the 16 participants had Heme occult positive; 1 or these 4 had multiple erosion at the splenic flexure, I had rectal polyp noted at colonscopy. Five participants had anemia, 1 of these had positive fecal occult blood. There were significant changes in the following haematological parameters:iron (decreased, p<0.05), ferritin(decreased, p<0.05), TIBC(increased, p<0.01) after race. Gastrointestinal symptoms and gastrointestinal mucosal changes are prevalent among long distance runners. Gast-ronintestinal endoscopy should be performed in long distance runners with symptoms and/or anemia prior to treatment.
