목 적 : 정 신분열병 환자의 자기만입 정도에 영향을 미치는 인구학적 변인들 및 질병연관 변인들을 규명해 보고자 하였다. 또한. 환자들의 자기만입과 병식 사이의 연관성. 자기만입과 자존심 사이의 연관성을 알아보고자 하였다. 방 법 : 정신과 의사가 병록지와 면담을 통하여 대상 정신분열병 환자들의 인구학적 변인들 및 질병연관 변인들에 관한 자료를 얻고 환자들의 병식 정도를 평가한 후, 환자들로 하여금 자기보고형의 자기만입 척도와 자존심 척도를 시행하게 하였다. 총 111명의 환자가 연구대상으로 선택되었다. 결과: . 1) 여자가 남자보다 유의하게 높은 자기만입 척도 점수를 나타내었다 2) 질병연관 변인들 중 하위집단 사이에 자기만입 척도 점수의 유의한 차이를 보이는 변은 없었다. 3) 자기만입 척도 점수와 병식 점수 사이에 유의한 상관관계가 없었다. 4) 자기만입 척도 점수와 자존심 척도 점수 사이에 유의한 역상관 관계를 보였다. 결 론 : 본 예비 연구의 결과로 보아 정신분열 병 환자의 병식이 부족한 상태에서도 자기만입이 진행될 수 있으며. 자기만입이 심할수록 환자의 자존심이 저하되는 것으로 생각된다. 또한 여자 환자들이 남자 환자들보다 자기만입에 더 취약한 것으로 생각된다. 따라서 정신분열 병 환자의 이해와 치료를 위하여 자기만입에 관한 지속적인 연구가 필요할 것으로 생각된다. objective : This study was conducted to identify demographic variables and illness related variables which may affect the severity of self-engulfment in the patients with schizophrenia. We also studied the relationship between self-engulfment and insight, and the relationship between self-engulfment and self-esteem. Methods : Data on demographic variables and illness related variables for the subjects were gathered from hospital records and clinical interviews by the psychiatrists. Degree of insight for the subjects was assessed through clinical interviews by the psychiatrists. Degree of self-engulfment and self-esteem for the subjects was assessed from the self-engulfment scale and the self-esteem scale respectively. A total of 111 patients with schizophrenia were selected for statistical analysis. Results 1) The females exhibited significantly higher scores than the males on the self-engulfment scale. 2) There was no illness related variable, which exhibited a significant difference among subgroups on the self-engulfment scale. 3) There was no significant correlation between the self-engulfment scores and the insight 4) There was a significantly inverse correlation between the self-engulfment scores and the self-esteem scores. Conclusion : The results of this preliminary study suggest that self-engulfment may develop despite lack of insight and that there was inverse relationship between self-engulfment and self-esteem in the patients with schizophrenia. It also suggests that females are more subject to self-engulfment than males. So, authors suggest that it is valuable to do further studies of self-engulfment in the patients with schizophrenia.

This paper represents to develop a computer software system which is capable to analyze the phase transformation of high strength steel(BV-AH32) and to predict heat transfer and welding residual stress due to phase transformation during Gas Metal Arc(GMA) welding. The developed model was considered temperature dependent properties such as young's modules, coefficient of thermal expansion and yield stress as well as the double ellipsoidal heat distribution by the moving arc. From the results, it was found that the longitudinal and transverse residual stresses calculated by the coupled analysis of heat transfer, residual stress and phase transformation showed good agreement with the experimental data. In addition, the temperature distribution as well as longitudinal and transverse residual stresses of weldment by the 1-pass and 2-pass of welding were also determined.

Cerebral arteriovenous malformation is a rare cause of congestive heart failure in neonates and is known to carry a very poor prognosis even wish prompt recognition and aggressive treatment. We recently encountered a 2-day-old male neonate with huge cerebral arteriovenous malformation who presented with intractable heart failure. Despite aggressive medical treatment and partial embolization with detachable balloon, baby died of severe hearts failure. Since there is no report of percutaneous balloon embolization in a neonate with this lesion in Korean literature, we wish to present our experience in one such neonate. Also we believe this is the first report of color Doppler findings in cerebral arteriovenous malformation in Korean literature.

Objective : Surgical experiences of pseudoaneurysms such as traumatic, mycotic and ill-defined unknown causes of aneurysms are rare. The authors have studied the results of surgical management from such cases in our series. Patients and Method : In the last 17 years, 1320 patients with cerebrovascular aneurysms were managed surgically. Among these, 16 patients showed the pseudoaneurysms. The authors analyzed retrospectively the clinical characteristics, treatment methods, management outcomes and problems in the managements. Results : There were 6 patients with traumatic aneurysm, 4 mycotic aneurysms and 6 ill-defined unknown causes of aneurysm. The sites of traumatic aneurysms were cavernous portion of the internal carotid artery(n=3), distal portion of the anterior cerebral artery (n=2) and vertebral artery(VA : n=1). Good outcomes in 5 cases could be obtained by extracranial - intracranial bypass followed by parent vessel occlusion or resection of aneurysm followed by re-anastomosis of parent vessel. The sites of mycotic aneurysm were peripheral portions of middle cerebral artery(MCA : n=3) and posterior cerebral artery(PCA : n=1). The outcomes of the patients with a mycotic aneurysm were relatively poor. It was partially due to the development of new aneurysm after treatment in one. The sites of ill-defined unknown causes of aneurysm were extracranial carotid artery(n=3), V2 portion of the VA(n=1), peripheral portion of the PCA (n=1) and MCA(n=1). Good outcome in all cases could be obtained by resection of aneurysm with or without saphenous vein graft. Conclusion : For the treatments of cerebrovascular pseudoaneurysm, combinations of aggressive medical, endovascular and surgical managements seem mandatory. Insertion of stent for a extracranial carotid artery aneurysm and coiling for a peripheral mycotic aneurysm can be option in future.

N/A We obserbed 24 cases of tsutsugamushi disease occur- ring in the Gang-Won-Do area from September to October 1988, which were confirmed by indirect immunofluorescent antibody test, and analysed their clinical findings. On physical examination eschars which can be a clinical clue to tsutsugamushi disease in the early stage of infection were recorded in 11 cases (45%). Common laboratory features included thrombocytopenia in 19 cases (95/o), and increased SGOT in 22 cases (92%), SGPT in 49 cases (79%), LDH in 19 out of 20 cases (95%) tested, CK in 7 out of 20 cases (35%) tested and serum ADA level in 12 of 13 cases (92%) tested. Serum fibrinogen was decreased in 5 of 13 cases (38%) tested, FDP was positive in 8 of 13 cases (62%) tested and prolonged prothrombin time was observed in 9 cases (38%). When IgM and IgG titers were measured separately, two distinct responses were seen. The IgM titers gradually declined during the period from 14-40 days. The IgG responses in the same patients developed more slowly. In our study, tsutsugamushi disease was a mild to severe febrile illness of 1 to 2 weeks duration. We think that more concern about tsutsugamushi disease is necessary because of possible mortality in poorly treated cases as well as a need for more precise differential diagnosis of acute febrile illness.

As the rapid growth of industrial society, many enterprises are inclined to 100 ppm management, even more to ppm management from the traditional 3σ management method. Therefore, it needs to extend process capability index for guarantee of high quality assurance level to ppm unit. Thus, in this paper, using the probability of standard normal distribution from 3σ tp 6σ, which was developed by an author, the optimal numbers of inspection facility is determined for guarantee of process capability index and quality assurance level. Also, high quality assurance level is determined by considering the precision of inspection when one and two sided specification is given for the probability which is out of the specification limit.

This paper reviews a study for the replacement energy. Since the first oil shock has already made it of enhancing public awareness of energy savings, the need for an efficient use of the existing energy and developments of a new form of energy resources have been increased. Furthermore, environmental concerns about emissions from fossil fuels and shortage of fossil resources have also stimulated increased interest in replacement energy including solar, wind, wave, biomass and hydro. In this paper, we discuss the technology and the trend of the replacement energy.

HVDC(High Voltage Direct Current) 송전 기술에 관한 연구

이영일 수원대학교 산업기술연구소 2004 산업기술연구소논문집 Vol.19 No.-

This paper reviews a study for HVDC(High Voltage Direct CurrenT) transmission. The first high-voltage dc transmission plants appeared more than 40 years ago. However, early in the development of electrical power, AC came to dominate as a means of interconnection between generation plants and machinery. Despite AC being the dominant mode for power trnamission, HVDC is often the preferred option in a number of applications, such as in submarine cables and in interconnecting unsynchronized AC systems. In this paper we study the technology of HVDC transmission.

This paper dose not show a physical or mathematical explanation or an experimental result. Rather, it discusses communication methods of the telemetry and the system of telemetry is called the automatic meter reading system (AMRS). The AMR system consists of three main part; a remote measuring unit, a central control unit and a data communication unit. In this paper, several data communication methods were compared with each other. The PLC (power line carrier) method to transmit the data between the measuring unit and the control unit was discussed deeply.
