The purpose of this study was to offer the fundamental materials to activate mountaineering the National Park mountains and to improve the Pukansan National Park system through analyzing satisfaction grade of the climbers using the Pukansan. Before the real survey of this study, the satisfaction grades were summarized six factors these were most interested in types and ages of mountaineers. They were constituted of number and location of the facilities, facilities management, public relationship, system, and the staff. The independent variables were the social economic characteristics: gender, age, occupation. And the dependent variables were six satisfaction grades: number and location of the facilities, facilities management, public relationship system, and the staff. After data analyzed, the 300 objects were investigated in the Pukansansong course, Daenammun course and Uidong course through the optimally prepared questionnaire. Frequency analysis and One Way ANOVA were used for data analyzing. Through the above methods, the difference between the groups classified by socialeconomic characteristics and mountaineering-form characteristics were followed; 1. The facilities management was the most high satisfaction grades of all mountaineers, and after that, system, staff, facilities location, location, public relationship and facilities number were listed. The facilities managiment, system, staff, facilities location were 3 grade(So-so), the public relationship and facilities number were close 2 grade (dissatisfied), low satisfaction grade. 2. The mountaineer's satisfaction grade according to the social·economic characteristics; (1) The satisfaction about facilities number showed the difference among the groups classified according to gender, age, occupation. (2) The satisfaction about facilities location showed the difference among the groups classified according to age, occupation (3) The satisfaction about facilities management showed the difference among the groups classified according to gender, age, occupation. (4) The satisfaction about public relationship showed the difference among the groups classified according to occupation. (5) The satisfaction about the system showed the difference among the groups classified according to occupation. (6) The satisfaction about the staff showed the difference among the groups classified according to occupation.

중성자에 조사된 원자로 압력용기 재료(SA508)의 Magneto-acoustic emission 효과

홍준화,박덕근,옥치일,김장환,이종규 韓國非破壞檢査學會 1999 한국비파괴검사학회지 Vol.19 No.6

원자로 압력용기 재료인 SA508 steel을 온도 70 ℃와 대기압하에서 최고 10 n/㎠까지 중성자를 조사시켜 조사량에 따른 미세경도 변화와 magneto-acoustic emission(MAE) 에너지를 측정하였다. 중성자 조사에 따른 경도의 변화는 조사량이 10 /㎠까지는 거의 일정하였으나, 조사량이 10 /㎠이상에서 급격히 증가하였다. MAE 에너지의 변화는 중성자 조사량에 따라 경도의 변화와 같은 형태로 변하였으나 그 변화량은 감소하여 그변화의 추이는 경도의 변화와는 역의 형태였고, 또한 MAE에너지의 상대적 변화와 경도 변화사이에는 아주 좋은 선형성을 보였다. 이러한 결과에서 SA508 강재는 10 /㎠이상의 중성자에 조사될 경우에 재료에 중성자 조사에 의한 미세 결함이 급격히 증가하여 전위(dislocation)이동에 대한 저항성을 나타내는 마찰경화의 증가가 경도의 증가를 유발하고, 또한 이러한 미세 결함은 자기장과의 반응에서는 90°자벽의 운동중에 자기탄성 변화를 유도하여 MAE 에너지의 감소를 유발함을 알 수 있었다. 그리고 경도의 변화량보다 MAE 에너지의 변화량이 더 크게 나타나, 중성자 조사에 의한 미세결함은 기계적 성질보다 자기적 성질에 더 민감하게 반응한다는 것을 알 수 있었다.따라서 MAE가 중성자 조사에 의한 재료의 미세 구조 결함을 비파괴적인 방법으로 평가하는 강력한 도구의 가능성이 있음을 알 수 있었다. Magneto-acoustic emission (MAE) energy and hardness were measured in the reactor pressure vessel steel (SA508 Steel) for the various neutron fluence, irradiated dose up to 10 n/㎠. The hardness was nearly a constant up to 10 n/㎠, but it was rapidly increased with an increase of the neutron irradiation above 10 n/㎠. It may be considered that the increase of hardness is due to the hindrance of dislocation motion induced defect clusters by irradiation. On the other hand, the MAE energy was slowly decreased as the neutron irradiation increased up to 10 n/㎠ and it was rapidly decreased with an increase of the neutron irradiation increased up to 10 n/㎠ and it was rapidly decreased with an increase of the neutron irradiation above 10 n/㎠. The decrease of the MAE energy may be considered as an increase of the defect clusters which is very sensitive to the 90°domain wall motion. Furthermore, the change of MAe energy and hardness had nearly a linear relationship, but the change of MAE energy was more significant than the change of the hardness. Therefore, MAe may be considered as a very useful technique for the nondestructive evaluation of irradiation damage.

옥치일,김장환,박덕근,홍준화,이종규 韓國非破壞檢査學會 1998 한국비파괴검사학회지 Vol.18 No.6

원자로 압력용기 재료인 SA508 steel을 온도 70℃와 대기압하에서 최고 10 n/㎠까지 중성자를 조사시켜 조사량에 따른 자기이력곡선과 Barkhausen noise amplitude(BNA), Barkhausen noise energy(BNE) 및 미세경도 변화를 측정하여 이들 사이의 상관관계를 구하였다. 중성자 조사에 의하여 자기이력곡선은 변화가 없었으며, BNA, BNE 및 경도는 중성자 조사량에 따라 세 단계의 변화를 보였으며, 중성자 조사량이 10 n/㎠에서는 급격히 변하여 이들 사이의 상관관계가 있음을 알 수 있었다. 따라서 BNA와 BNE가 중성자 조사에 의한 재료의 미세 구조 결함을 조사하는데 비파괴적인 방법으로 가능성이 있음을 알 수 있었다. Hysteresis loop, Barkhausen noise(BN), and hardness were measured in the neutron irradiated RPV steel for various fluence, irradiated dose up to 10 n/㎠. The coercivity, remanence and maximum induction of neutron irradiated samples did not change significantly, but the BNA and BNE were decreased as the neutron irradiation increased. The changes of BNE and BNA were characterized by three stages with respect to neutron dose. The BNA and BNE were decreased with an increase of neutron dose to 10 n/㎠, and remained nearly constant up to 10 n/㎠, then were decreased rapidly with an increase of the neutron dose above 10 n/㎠. On the other hand, the hardness was observed revesely with the change of BNA and BNE.

금융부문의 유사행정규제에 관한 연구

이혜영(Lee, Hye Young),박장호(Park, Jang Ho),최성락(Choi, Seong Rak),주용환(Joo, Young Whan) 한국경제연구원 2011 규제연구 Vol.20 No.2

현 정부의 다양한 규제개혁 성과에도 불구하고 우리나라에서 금융부문은 여전히 규제가 과다한 대표적인 영역으로 인정되고 있다. 그러나 실제 규제개혁위원회에 등록된 금융부문 등록 규제는 전체 등록 규제의 7% 정도로 나타나고 있으며 이것만으로는 금융부문의 규제가 과다하다고 말하기 어렵다. 본 연구에서는 이와 같이 국민이 체감하는 규제와 등록 규제 정도의 차이가 발생하는 주요 원인의 하나가 금융부문 공공기관의 유사행정규제인 것으로 파악하고, 금융부문에서의 유사행정규제를 분석하고 이를 규제개혁위원회 등록 규제와 비교 하였다. 이를 통해 금융부문 규제개혁에 대한 시사점을 도출하였다. 금융위원회를 주무부처로 하는 7개 공공기관을 대상으로 정관, 약관, 내부 규정 등에 규정된 유사규제를 분석한 결과 총 534건의 유사행정규제가 도출되었다. 금융 관련 등록 규제의 약 60% 정도가 추가적으로 유사행정규제 형태로 존재하고 있으며, 의무부과에 해당하는 비중이 컸다. 즉 국민들이 체감하는 금융규제는 등록 규제와 유사행정규제를 합한 부문으로 볼 수 있으며, 금융부문 유사행정규제는 규제개혁 체감도를 낮추는 주요 원인이 되고 있다는 것을 확인할 수 있었다. 따라서 향후 금융부문 규제개혁을 추진하는 데 있어서 유사행정규제에 대한 고려가 필요하다. Lee Myeong Park's government has pursued regulatory reform since 2008, but many people think that there are too many regulations in the financial sector of Korea. In Regulatory Reform Committee, all the regulations of government are registered, and the registered regulations of the financial sector are only 7% of all regulations. But people think that regulations of the financial sector become increased. We assumed that the reason would be existence of agency regulations. Therefore, in this article, we tried to analyze the regulations of agencies in the financial sector. We analyzed 7 public institutions in the financial sector, and found 534 agency regulations in total. Officially, the registered regulations in the financial sector are 843, but there are 534 more regulations if we consider regulations of public agencies. It is necessary to think about regulations of public agencies when we seek to regulatory reform in the financial sector.

Rhabdomyolysis may be defined as a clinical and laboratory syndrome which releases muscle cell contents into the plasma, such as creatine phosphokinase, due to skeletal muscle injuries. It can be the result of many diverse causes including muscle disease, ischemia, genetic disorder, metabolic disorder, infectious disease, drugs, comatose state, trauma or vigorous exercise that can lead to acute renal failure as a complication. Since first reported in 1941, rhabdomyolysis-induced acute renal failure has been documented many times, and the major causes of this disease are carbon monoxide poisoning, snake bites, and etc in Korea Reports of acute renal failure after exercise-related rhabdomyolysis with myoglobinemia are rare. We report a case of acute renal failure caused by exercise-related rhabdomyolysis in a 20 year old man.

Primary Synovial Sarcoma of the Thyroid Gland

Jang, Ki-Seok,Min, Kyueng-Whan,Jang, Si-Hyong,Paik, Seung Sam,Tae, Kyung,Jang, Se Jin,Park, Moon Hyang KOREAN ACADEMY OF MEDICAL SCIENCE 2007 JOURNAL OF KOREAN MEDICAL SCIENCE Vol.22//SUP No.-

<P>Synovial sarcoma is a rare but distinct soft tissue neoplasm, most commonly occurring in para-articular regions of the extremities of young adults and also occurring in the head and neck region. To the best of our knowledge, only one case of primary synovial sarcoma of the thyroid has been previously reported. Here, we report a 15-yr-old man who had a chief complaint of a palpable neck mass. The neck computed tomography revealed a relatively well-demarcated solid mass in the left thyroid gland. After fine needle aspiration cytology, total thyroidectomy and lymph node dissection were performed. Grossly, the mass was covered by the same capsule as the thyroid gland, measuring 6×5×5 cm in dimensions and weighing 78 gm. The cut surface showed a well demarcated, lobulated, grayish tan, and rubbery solid tumor. Histologically, this tumor was a biphasic synovial sarcoma. Immunohistochemical, ultrastructural, genetic studies, and cytologic findings were all consistent with synovial sarcoma. When synovial sarcomas arise in this unusual site, recognition and differential diagnosis become more difficult. The differential diagnosis of a spindle epithelial tumor with thymus-like differentiation is very difficult due to their similar clinical, histological, and immunohistochemical features. Ultrastructural and cytogenetic studies for synovial sarcoma are necessary to establish a definitive diagnosis.</P>
