박윤규,송봉환 최신의학사 1975 最新醫學 Vol.18 No.3
The authors' report a case of spinal intradural arteriovenous malformation: involving the cervicothoracic spinal cord. Chief complains of the patient who was 27 year-old office man were quadriparesis and girdle pain in both upper extremities. The malformation was diagnosed by pantopaque myelography and clipped under the operatiig microscope.

박윤규 용인대학교 산업경영연구소 1997 산업경영논총 Vol.2 No.-
The overall effect of the Unemployment Insurance(U) program on unemployment may be theoretically ambiguous because eligibility for benefits also increases the attractiveness of taking a new job that is covered by UI, but the general presumption is that higher UI benefits increase the length of the unemployment spell, on net. Although the results of many studies vary widely depending on the specific sample used, the previous variables chosen for the analysis, and the econometric techniques employed, the general finding is that a higher wage-replacement ratio is correlated with a longer unemployment spell. Much of the controversy over UI has centered on the effect of the U program on the unemployment rate. Fiscal and monetary policies that are designed to deal with aggregate demand failures may lead In unacceptable rate of inflation when they are used to reduce UI-induced unemployment. We have no a priori prediction of UI effects on labor turnover. It can go either way, but which way it goes will likely vary with worker skill levels, between industries, and with general business conditions.

정섬,유원민,박병윤,박윤규 大韓成形外科學會 1999 Archives of Plastic Surgery Vol.26 No.5
Surgical excision of the subcutaneous tissues, with or without skin excision in the axillary hair-bearing area, has been the treatment of choice for Treating axillary a osmidrosis for the several decades. However, long periods of postoperative immobilization of a shoulder joint, partial necrosis of skin flaps or hematoma and the possibility of unsightly scars are frequent complications. For the purpose of reducing these complications, we performed ultrasonic aspiration of subcutaneous fat of the axilla, including the apocrine gland, using ultrasonic liposuction technique under confirmation of endoscopy via one small skin incision. From November 1997 to December 1998, a total of 134 patients (93 women and 41 men) received surgery for bilateral axillary osmidrosis on an outpatient basis. Sixty patients were evaluated more than 6 months after surgery. Among these patients, 6patients complained of a persistent foul odor(10%). Five patients received secondary ultrasonic aspiration for persistent foul odor and were then cured. We concluded that our method has several advantages such as 1) preservation of skin flap vascularity for the prevention of flap necrosis and axillary hair, 2) minimal scarring and bleeding, 3) shorter operation time and postoperative immobilization of the shoulder joint, 4) increased patient comfort, and 5) a safer operative method for recurred cases as a secondary method.

γ-Glutamyltranspeptidase가 肝細胞增殖에 미치는 影響
朴鈗圭,柳總根 고려대학교 의과대학 1992 고려대 의대 잡지 Vol.29 No.1
This study was intended to examine the role of γ-Glutamyltranspeptidase (γ-GT) in controlling hepatocyte proliferation and the mechanism of the enzyme action by which the enzyme manifests such effect. Adult rat hepatocytes were isolated and cultured to observe normal growth pattern. and the effect of inhibitor (serine-borate complex) of γ-GT upon hepatocyte proliferation, and to decide the concentration of enzyme inhibitor at which hepatocyte proliferation is inhibited. In addition. Changes of γ-GT activity and DNA synthesis were studied in the absence or presence of enzyme inhibitor employing primary culture of hepatocytes. The following results were obtained 1. Low initial cell density (5-6×10^(5)' cells/3S mm dish) and addition of insulin and EGF prompted hepatocyte proliferation. Whereby, Cell number increased up to 1.5 fold after 32 hours in comparison with initial cell number. 2. The concentration range of enzyme inhibitor in which hepatocyte proliferation was inhibited was more than 1 mM 3. During primary culture of hepatocytes, γ-GT activity showed rapid increase in lag phase on the basis of "zero" time and maximal increase in exponential growing phase. The increasing rate of γ-GT was weakened in stationary phase. 4. During primary culture of hepatocytes. The extent of DNA synthesis showed rapid increase in lag phase on the basis of ''zero" time and gradual increase in exponential growing phase and stationary phase. But. Such increase of DNA synthesis was lost by administration of enzyme inhibitor. The above results suggest that action and increased activity of γ-GT is necessary for increase of DNA synthesis in hepatocyte proliferation.

要約 地理情報 시스템이란 현재 美國警察의 일부가 사용하고 있는 전산화된 地圖體制로서, 경찰이 자기 관할구역 내에 있는 犯罪多發生地域 즉, 우범지역을 확인할 수 있게 하는 시스템이다. 미국의 경우, 경찰을 포함하여 刑事司法機關에서 GIS를 이용하기 시작한 것은 10年이상 되었으나 현재까지 GIS를 도입하여 활용하고 있는 경찰관서의 수는 사실 그리 많은 편은 아니다. 이 시스템은 지리적 정보와 범죄에 관한 각종 통계치를 결합시키고 있다. 어떤 환경적 요인과 연관되지 않은 범죄는 사실상 예측하기가 어렵다. 그러나 GIS를 활용하여 '場所中心의 犯罪管理'를 함으로써 특정한 장소와 관련된 범죄는 줄어들고 있다. GIS를 활용하면, 경찰관들은 자기들이 어디로 가야하고 관할구역 내에서 범죄에 대처할 때 시간을 어떻게 효율적으로 배분해야 하는지를 알게 된다. 게다가 GIS는 지역주민들이 이웃에서 발생할지도 모를 범죄를 事前에 예방할 수 있도록 동참하게 해 준다. 경찰과 주민 양쪽 다 어디에 문제가 있는지를 알기 때문에 범죄를 줄이는 노력을 함께 함으로써 경찰과 주민간의 同伴者關係 즉, 結束力을 강화시킨다. 과학기술이 발달함에 따라서 범죄는 더욱 복잡해지고 범죄자는 더욱 교활한 방법을 사용한다. 다가오는 21세기에 완벽한 치안유지를 위해서 情報化時代의 경찰은 GIS와 같은 뛰어난 기술로 무장해야만 한다. GIS는 경찰이 자기의 고객인 지역주민들에게 더 나은 서비스를 제공하기 위해서 반드시 갖추어야 할 중요한 기술인 것이다. 또한 경찰의 GIS 사용을 촉진하기 위해서는 GIS에 관한 연구가 더 많이 이루어져야 한다. 학자들의 연구가 GIS 사용의 有益性을 발견해내고 이를 학문적으로 뒷받침한다면 경찰이 一線에서 GIS를 활용하는 데에 따른 어려움은 줄어들 것이다.
