The purpose of this study was to investigate the effects of detraining and retraining on serum lipid and hormones in soccer players. Subjects were seven male high-school soccer players. V˙O_2max was determined for each subjects by administering a treadmill test(initial speed: 90m/min, grade: 5%, increasing speed per 3 min: 30m/min). Serum lipid(T-C, TG, HDL-C LDL-C) and hormones(epinephrine, norepinephrine, growth hormones, cortisol) were assayed pre and post detraining in 10, 20, 30 days after retraining. The repeated ANOVA was used to determine significant differences. The 0.05 level of significance was as critical level for the study. The results of the study were as follows: 1. V˙O_2max(ml/min) were 3576.3±204.2ml/min pre detraining, 3234.1±198.9 ml/min post detraining. There are significant(p<.05) difference between pre and post detraining. In 10, 20, 30 days after retraining, V˙O_2max(ml/min) were 3601.4±170.9 ml/min. There were significantly(p<.05) increased in retraining periods. 2. V˙O_2max(ml/kg/min) were significantly(p<.05) decreased from 62.3±2.9 ml/kg/min to 55.9±4.7 ml/kg/min in detraining. In 10, 20, 30 days after retraining, V˙O_2max(ml/kg/min) were 62.4±3.4ml/kg/min, 62.7±2.3ml.kg/min, 67.3±7.2ml/kg/min respectively. There were significantly(p<.05) increased in retraining periods. 3. T-C were significantly (p<.05) increased from 166.6±8.5mg/dl to 175.3±10.3 mg/dl in detraining. In 10, 20, 30 days after retraining, T-C were 160.1± 3.2mg/dl, 156.7±3.7mg/dl, 140.3±9.0mg/dl. There were significantly(p<.05) decreased in retraining periods. 4. HDL-C were 61.4±6.6mg/di pre detraining, 5.3±6.6mg/dl post detraining. There are significant(p<.05) difference between pre and post detraining. In 10, 20, 30 days after retraining, HDL-C were 56.9±7.1mg/dl, 56.4±9.2mg/dl, 57.7±9.1mg/dl respectively. There were no significant difference in retraining periods. 5. The hormones(epinephrine. norepinephrine, growth hormone, cortisol) were changed as same patterns. Epinephrine were 26.0±7.0[g/ml pre detraining, 24.6±3.2pg/ml post detraining. In 10, 20, 30 days after retraining, epinephrine were 26.9±5.6pg/ml, 30.6±6.2pg/ml, 29.4±5.6pg/ml respectively. There were no significant difference in retraining periods. In conclusion, HDL-C, epinephrine, norepinephrine, growth hormone and cortisol were decreased, T-C, LDL-C and TG were increased in detraining. But HDL-C, epinephrine, norepinephrine, growth hormone and cortisol were increased, T-C, LDL-C and TG were decreased in retraining.

Purposes of this study were 1) to identify the level of role expectation and role performance for school health educators as elementary school students recognize and to compare them, and 2) to examine differences in the role expectation and performance by characteristics of students and educators. Subjects of the study were 1,428 6th grade students at 37 elementary schools in Busan. The data were collected by a structured self-administered questionnaire, measuring role expectation and performance that students recognize. The data were analyzed with descriptive statistics, t-test, and ANOVA by SPSS program. The results were summarized a s follows. 1. Students' level of recognizing the role expectation was high(M=4.08) and level of the role performance was moderate to high(M=3.50) within rang of 1 to 5. The students recognized role expectation greater than role performance. 2. The students' point of view for role expectation and performance for school health educators were related to several characteristics of students and school health educators. Students' levels of recognizing the role expectation and performance were higher when students were male, healthy, their academic performance was high, their level of satisfaction with their school life was high, and their level of satisfaction with using school health office was high. With characteristics of school health educators, students' level of appreciating the role expectation was higher when educators were of an older age and had a long career, and when they were fairly satisfied with their job as an educator. Students' level of recognizing the role performance was higher when educators were of a younger age, and had a small number of students at school. This indicates that there exists role conflict on students and implies that the conflict need to be mediated, and desirable solutions to address the conflict need to be developed by school health educators.

정희석,강욱,이철현 한국목재공학회 2002 목재공학 Vol.30 No.2

변장 14.0 ㎝와 16.5 ㎝인 소나무 정각재의 가열판진공건조와 고주파진공건조간의 건조속도, 함수율분포와 比에너지를 비교하였다. 고주파진공건조는 가열판진공건조보다 건조속도 및 변장이 건조속도에 미치는 영향이 컸었다. 가열판진공건조 목재의 재장방향, 두께방향과 폭방향의 함수율분포는 볼록 형태를 나타내었고, 고주파진공건조 목재는 오목 형태를 나타내었다. 가열판진공건조 목재의 폭방향과 두께방향간의 수분경사는 유사하였으나 고주파진공건조 목재의 경우는 폭방향의 수분경사가 두께방향보다 완만하였다. 가열판진공건조와 고주파진공건조의 比에너지곡선은 함수율이 감소할수록 증가하는 경향을 나타내었고, 가열판진공건조의 比에너지는고주파진공건조보다 컸었다. Red pine(Pinus densiflora) square timbers with 14.0 ㎝ and 16.5 ㎝ of face size and 2.4 m long were dried in a vacuum-press kiln and in a radio-frequency/vacuum(RF/V) kiln to compare drying rate, moisture content(MC) distribution and specific energy. RF/V drying rate was higher than vacuum-press drying rate. The effect of size of cross section on the RF/V drying rates were more pronounced than those of vacuum-press drying. The longitudinal- and the transverse MC distribution of dried square timber showed convex profile for the vacuum-press drying and concave profile for the RF/V drying. Moisture gradient of width direction was similar to the thickness direction in vacuum-press dried square timber and was more slight than that of the thickness direction in the RF/V dried large square timber. The specific energy consumption curve increased as MC decreased. Specific energy(kWh/㎏ of water evaporated) of the vacuum-press process required more than that of the RF/V process.

이 논문은 소나무와 일본잎갈나무의 변장 14.0cm와 16.5cm인 큰 정각재의 천연건조과정과 함수율분포에 관한 내용으로서 건조속도는 건조개시 첫 8주 동안 비교적 컸었으나 그 이후부터 점차 감소하였다. 생재에서 규격함수율 18% 수준까지 건조시간은 소나무 14.0cm와 16.5cm가 각각 26주와 32주이고, 일본잎갈나무의 경우는 각각 32주와 48주이었다. 이들 정각재의 재장방향과 두께방향의 수분경사는 비교적 완만하였다. 일본잎갈나무의 수분경사는 소나무의 것보다 컸었고, 일본잎갈나무의 변장의 크기가 수분경사에 미치는 영향은 소나무의 것보다 컸었다. This paper presents the results of air-drying processes and mositure content (MC) distribution of red pine (P. densiflora) and Japanese larch (I. leptolepis) square timber with 14 cm and 16.5 cm of face size, respectively. The air-drying rates of square timber were comparatively high during the first 8 weeks, after that gradually decreased. The time to air dry square timber from initial MC to specified MC of 18 percent required about 26 weeks for 14.0 cm and 32 weeks for 16.5 cm square of red pine, and 32 weeks for 14.0 cm and 48 weeks for 16.5 cm square of Japanese larch. The longitudinal-and transverse MC distribution of these air-dried squares showed slight moisture gradient. The effect of face size on moisture gradient of Japanese larch square was more pronounced comparing with red pine one.

러시아연방의 한반도정책과 한러관계

정희석 효성여자대학교 법정연구소 1998 법정연구 Vol.5 No.-

The Russian Federation which emerged as a legal successor to the Soviet Union started to pursue tilt-South Korea policy that concentrates on economic aid from Korea in an effort to restore the falling domestic economy complying with its world policy as westernism. At the moment, South Korea gives priority to the political interest, that is using the Russian Federation as the leverage to improve the relationship with the North. Both South Korea and the Russian Federation expected they could find a common ground and had a smooth start implementing legal and institutional measures. However, the expectation on neither side were met; hence the conflicts between the countries were to be revealed. South Korea's high-handed attitude and inhospitable treatmemt toward Russia derived from the overconfidence of economic power, and the attitude and the process of economic cooperation made Russia reassess the interest relationship with South Korea and recognize the importance of recovering the relationship with the North only to change the policy on the Korean Peninsula. That means the Russian Federation has come to maintain the balance between geographical and economic interests and has pursued aggressive policy on the peninsula which is balanced policy. Even after recognizing the limitation of the economic cooperation with Russia due to the political and economic unstability, the South is linking the economic cooperation with Russia directly with obtaining the influencing power to the North, which has been hampering the Russia's amour propre. Also by excluding Russia in the talks on the peninsula bound by the frame of US-South Korean alliance and by prioritizing the relationship with China to that with Russia, has South Korea intensified the Russia's sense of alienation. Consequently, the Russian Federation adhering to the principles on various fields to retrieve its pride and to strengthen the power of influence on the Korean Peninsula, despite the external growth, the conflicts between both countries have accumulated failing to sustain the helpful cooperative relations. South Korea whose main tasks in the 21st century diplomacy are to accomplish the reunification with North Korea and to leap to be the center state in the Asian-Pacific region has to acknowledge it should concentrate on cooperative relationship with the Russian Federation. To do so, South Korea should instate the relations with Russia on an equal footing with other super powers on the issues of the Korean Peninsula and the Northeast Asia which will prevent Russia's arbitrariness as a great power. Furthermore, as the reform that Russia has been pursuing is the key environmental factor, South Korea will be able to seek the support and cooperation of Russia if it maintains the friendly relations with the counterpart contributing to the process of Russia's reform. South Korea now has to cease the war of attrition with Russia triggered by abnormal diplomatic behavior and to face the South Korean-Russian relations on a long term.

진공증착방법으로 제작한 Ni_53-Fe_47 박막에 관한 신형전류자기 기전력효과의 전류와 자장 방향이 만드는 각 θ 의존성이, 자기저항효과의 cos 2θ, Hall 1 효과의 경우 sin 2θ로 관측되고, 이 효과의 자장에 의존하는 전압변화율이 자기저항효과와 비교할 때 차수가 다르게 큰 것이 조사된다. 이 효과가 2 Carrier형 모델로 이해할 수 있음을 이론적으로 확인된다. A new Galvanomagnetic electromotive force effect of Ni_53-Fe_47 thin films is studied. The dependence of this effect on θ, angle between the current and the magnetic field, is found to be the form of sin 2θ, in contrast with that of the magnetoresistance effect cos 2θ and that of the Hall effect sin θ. Property of this effect is that the rate of the voltage variation depending on the magnetic field is extremely large as compared with the magnetiresistance effect. It is theoretically confirmed that this effect is well understood on the basis of the two carrier types model.

탈냉전 시대 유엔의 강제적 인권레짐의 형성배경과 실태

정희석,김도균 慶北大學敎 社會科學大學 2005 社會科學 Vol.17 No.-

본 논문에서는 잭 도넬리의 인권레짐 분석을 기초로 탈냉전 시대 유엔의 강제적 인권레짐의 형성배경과 실태에 대해 연구하였다. 잭 도넬리는 『국제인권 : 레짐분석』이라는 논문에서 국제인권레짐을 선언적 레짐, 장려적 레짐, 실행적 레짐, 그리고 강제적 레짐으로 분류하여 서술하고 있다. 그러나 그는 유엔에 의한 강제적인 인권레짐의 형성은 불가능한 것으로 보고 있으며 강제적 인권레짐이 형성되기 위해 「국제적인 의사결정」과 「국제적인 감시체제」가 형성되어야함을 설명하고 있다. 이러한 분석의 기준에 덧붙여 본 논문에서는 「국가주권에 대한 제한」 및 「국제법의 주체로 인식된 개인」을 강제적 인권레짐이 형성될 수 있는 기준으로 설정하고 그 시대적인 요인을 네 가지로 분석했다. 첫째, 구 소련과 구 동구권 공산국가들, 그리고 제 3세계 국가들의 민주화의 실패로 야기된 대규모 인권침해사태, 둘째, 세계화의 확대에 따른 정치적, 경제적, 사회적 측면에서의 인권침해 현상, 셋째, 저강도 분쟁으로 불리는 새로운 국제분쟁의 유형과 국내분쟁의 급증으로 인한 집단학살이나 대규모 살육과 같은 인권침해사태의 증가, 마지막으로, 인간안보를 중심으로 새롭게 대두된 신안보개념의 등장 등이 유엔에 의한 강제적 인권레짐의 가능성을 담보해낼 시대적인 요인이라고 보았다. 이러한 현실적인 유엔의 강제적 인권레짐 실태로는 심각한 인권침해를 저지르는 국가에 대한 유엔안보리의 인도주의적인 군사적 · 경제적 제재조치, 인도주의적인 관점에서 탈냉전 시대 변화해 가는 유엔의 평화유지활동, 전 세계적인 감시체제를 가동하면서 유엔의 인권정책을 통합한 유엔 인권고등판문관 활동, 그리고 심각한 인권침해를 저지른 각 국의 개인범죄자들을 처벌할 수 있는 국제형사재판소 활동 등을 들 수 있다. The purpose of this study is to analyze on the background and the realities of the United Nations' enforcement regime for human rights in post-cold war era. In 1986, Jack Donnelly presented the most prominent paper in the international human rights field called "International Human Right : A Regime Analysis." In the paper, he regarded international human rights activities as human rights regime and arranged the international human rights regime into four categories, declaratory regime, promotional regime, implementation regime, and enforcement regime. There are two major problems in his international human rights regime analysis. First of all, he insists that enforcement regime would be hard to be realized in the international society because of nation states sovereignty. Secondly. he ignores the important role of human rights Non-Government Organizations at the level of international politics. Because of the date of his thesis, he couldn't focus on human rights regime in the post-cold war era. This thesis gives the major reasons for the United Nations' enforcement regime for human rights. Why is United Nations' enforcement regime for human rights necessary in the world? First, the side-effect of democratization is more serious human rights violations in former Soviet Union and the Third World. Second, globalization has had a negative effect on human rights on the political, economic, and social level. Third, low-intensity conflict throughout the world has caused more death and injury than it did during the cold war and civil was has also broken out more frequently than interstate conflict since cold war. This means the United Nations peace-keeping operations have suddenly had to increase due to the increase of low-intensity conflict or civil war. Finally, a new security concept has replaced the traditional security concept. It mainly focuses on human security including social, economic, environmental security. This thesis mainly presents four major categories of the United Nations' human rights enforcement regime. These are the United Nations Security Council, the United Nations Peace-keeping Operations, the United Nations High Commissioner for Human Rights, and the United Nations International Criminal Courts.

직물유리섬유 강화집성재의 물리적 특성 (제1보) : 기계적 특성 Mechanical Properties

정인석,이원희,변희섭 한국목재공학회 2003 목재공학 Vol.31 No.5

본 연구는 국산소경재인 소나무(Pinus densiflora)재와 낙엽송(Larix kaemferi)재로 제조된 유리섬유강화집성재의 강도적 성질을 조사해 보기 위하여 실시되었다. 먼저, 직물 유리섬유를 수성고분자-이소시아네이트계(MPU-500) 접착제를 사용하여 control재와 유리섬유를 각각 1층과 2층 함입하였다. 본 연구의 결과는 다음과 같다 1. 수성고분자-이소시아네이트 수지는 집성재 제조용으로 적합하였으며. 특히 유리섬유를 2층 함입한 소재를 제외하고는 구조용 집성재의 품질기준(KS F 3021)을 만족시켰다. 2. 직물유리섬유를 함입할 경우 휨강도, 전단강도에서 control재보다 크게 뛰어나지는 않았지만, 비례한도 휨응력은 유리섬유의 함입 층수에 비례하여 증가하였다. 그러므로, 직물 유리섬유의 mesh수와 두께를 집성재 소재의 형태에 따라 적절히 조정한다면, 휨강도와 전단강도를 좀더 향상시킬 수 있을 것으로 판단되었다. This study was carried out to investigate the mechanical properties of fabric E-glass fiber reinforced laminated timber. Specimens used to Korean red pine(pinus densiflora) and Japanese larch(Larix Raemfert). Fabric E-glass fiber was inserted in the solid wood with aqueous polymer-isocyanate resin(MPU-500). The results were as follows: 1. Aqueous polymer-isocyanate resin(MPU-500) was good resin to manufacture laminated timber. specially, it was satisfied to property standard of construction laminated timher(KS F 3021) except for two ply glass fiber. 2. Bending and shear strengths of solid wood inserted with fabric glass fibers were not different from control solid wood. But, proportional limit bending stress was increased following the number of fabric glass fibers. Therefore, it was considered that to improve the bending and shear strength of fabric glass fiber reinforced laminated timber, the glass fiber thickness and its mesh should be modified to fitness following working conditions.
