소형 가솔린 엔진에 알코올 연료의 이용을 위한 기초 실험
이재순,박정규 건국대학교 산업기술연구원 1995 건국기술연구논문지 Vol.20 No.-
One of the realistic counterplanes for the global environment problem due to CO₂ is the conversion of petroleum oil to the alternative fuel in the end-use stage. As the first stage of this work, gasoline-alcohol blend has been chosen as the alternative fuel and the preliminary tests was performed to collect the basic data which show the performance and exhaust emission characteristics. Engine test for pure gasoline and pure alcohol were carried out to investigate the operating limit due to power, fuel consumption. ?? exhaust concentration, lean combustion limit, abnormal combustion such as knock. The alcohol sensor is indispensible for the engine in a FFV running an alcohol-gasoline mixture fuel to accurately determine the composition of the and to reliably set engine operating conditions. Here, the fundamental experiment were carried out for the development of the capacitance-type sensor having characteristics of compactness, low cost, and high reliability.

Machine failure is making Much trouble for the Production activity in many factories. In investigating the cause of machine failure, we should examine many things Such as the design of machine, the state of Construction, metallographic and machine analysis, and so on. Fracture modo of metal is related not only to its material but to the machine Conditions, which involve the shape of body, Kind of external forces and loading Velocity, and to environmental Conditions, which involve temperature, Corrosion and other things. As fatigue fracture of metal Occurs in accordance with the stress Correspondent to its fatigue strength, the Concurrence of working stress, obtained from machine Conditions of fatigue fracture state, and fatigue strength, determined from the shape and material of body, becomes "the failure Condition." If the stress level of fatigue strength is higher than that of Working sress, fatigue fracture will not occur. Here "Fracture Toughness of Machine Failure" is to be investigated.

박정규 한국서양사학회 2019 西洋史論 Vol.0 No.143
This paper examined largely the way in which the latitudinarians’ perspective on the political authority of the civil magistrate was shaped by their apocalyptic interpretation of the godly ruler. Recently, historians argue that their political thought was heavily influenced by Thomas Hobbes’ ideas because their central prepositions of the authority of monarchy showed little difference from Hobbes’ ideas. The accusation of ‘Hobbism’ against the latitudinarian clergy was made by a contemporary group of High Church apologists and Nonconformists. Both attacks were commonly directed at the insistence of the latitudinarians on the legitimate right of the civil rulers to control religious matters. Despite that some ideas that seemed slightly different from Erastianism, or Hobbism, were manifest in these moderates’ ecclesiology, it does not mean that the contending polemicists’ identification of the latitudinarians with ‘Hobbism’ is justified. Their attitude towards the duty of the monarch in religion and church matters was articulated mostly through religious language and rhetoric. In particular, their ideas of royal authority over the church were explained through the biblical understanding of political authority. Their view of the relationship between religion and politics should be understood as not so much one of inheritances of Hobbes’ worldview but as a part of the transformation of religious languages in politics in the later 17th-century England. 이 글은 잉글랜드 국교회 내 온건파인 광교파(Latitudinarians)의 정치사상, 특히 세속권력자의 권위와 그 역할에 대한 견해를 계시적 정치 수사인 ‘신성한 군주(godly ruler)’라는 개념을 통해 분석한다. 최근 학자들은 광교파의 정치사상이 토마스 홉스(Thomas Hobbes)의 정치이론에 직간접적으로 영향을 받았다고 본다. 그것은 광교파의 정치사상의 핵심 전제가 홉스주의적 면모를 보이고 있다는 이유에서이다. 광교파의 정치관은 당시 교회의 독립적 권위를 내세운 국교도 내 ‘고교회파(High-church)’ 성향의 성직자들 및 비국교도들에게 ‘홉스주의’의 세례를 받은 것으로 비춰지기에 충분했다. 고교회파 국교도와 비국교도는 서로 상반된 종교적 입장에도 불구하고 광교파가 홉스주의적 절대왕권론을 내세우고 있다는 비판을 한 목소리로 내었다. 최근 역사가들 역시 광교파의 정치사상과 홉스주의를 연결시킨 근거는 홉스의 핵심 원리와 광교파의 ‘세속적’ 정치사상의 유사성에 주목하여 17세기 후반 18세기 초에 걸친 광교파에 대한 비판적 논조를 암묵적으로 따르고 있다. 그러나 이러한 분석은 광교파의 군주와 교회와의 관계에 관한 언설만을 고려할 때 타당한 결론이다. 광교파 성직자들은 세속권력자에 대한 강력한 계시적 이상을 갖고 있었고 이는 그들이 강력한 왕의 대권을 옹호하는 데 가장 중요한 수사로 활용되었다. 더군다나 이들이 옹호한 왕의 대권과 수장권은 홉스가 주장한 절대왕권과 그 함의가 달랐다. 광교파의 주장에 홉스의 이론과 흡사한 부분이 존재한다면, 그것은 그들이 홉스의 유산으로 해석하기 보다는 16세기부터 이어져온 종교적 담론이 17세기 후반 이후 좀 더 ‘근대적’ 정치언어로 탈바꿈하는 과정으로 보는 것이 더 타당할 것이다.

Phlebosclerotic Colitis in a Healthy Young Woman
박정규,성영호,조선영,오창열,안소현 대한소화기내시경학회 2015 Clinical Endoscopy Vol.48 No.5
Phlebosclerotic colitis is a rare disease of intestinal ischemia and differentiating it from the typical ischemic colitis. It is caused by venous obstruction due to colonic and mesenteric venous calcification. We report a 36-year-old woman presenting with intermittent abdominal pain. Initial radiologic findings showed multiple tortuous thread-like calcifications in the region of the right side of the colon and transverse colon on plain abdominal radiographs and computed tomography images. In the colonoscopy, edematous dark-bluish colonic mucosa, sclerotic colon wall, and multiple ulcers without clear boundaries were observed from the ascending colon to the transverse colon. In the sigmoid colon only showed the edematous dark-bluish colonic mucosa, sclerotic colon wall. On the basis of these findings, we diagnosed the patient as having phlebosclerotic colitis. We report a rare case of phlebosclerotic colitis in healthy young woman.

상완신경총 손상 후 발생한 무증상의 척수강내거대 위수막류의 1예
박정규,박희원,이건재,백소라 대한근전도전기진단의학회 2014 대한근전도 전기진단의학회지 Vol.16 No.2
It is well known that a traction injury of the brachial plexus may produce tears in the root sleeves resultingin pseudomeningocele, which are in most instances small in size. Giant pseudomeningocele, largerthan 8cm in length, is very uncommon, and have been described rarely in symptomatic cases. Seventeenyears old male complained of left upper limb weakness after motorcycle accident in our case. An electrodiagnosticstudy showed panplexopathy, preganglionic lesion on C5-C7 root level and postganglioniclesion on C8-T1 root level. Giant pseudomeningocle, which was 12.9 cm in length in the spinal canalalong the cervical spine was shown on magnetic resonance image executed one month after accident. There were no symptoms due to intraspinal pseudomeningocele, except for symptoms due to brachialplexopathy. The authors report a first case of asymptomatic intra-spinal canal giant pseudomeningoceleafter brachial plexus injury.
