Stenosis of central vein is a common complication arising after percutaneous subclavian vein catheter insertion performed for temporary vascular access in chronic renal failure patients undergoing hemodialysis. There are several treatment methods for the condition like percutaneous angioplasty(PTA), stent insertion, and surgery, but recent trend is toward PTA and stents. Among the patients diagnosed with chronic renal failure from March 1993 to May 2002 and undergoing hemodialysis through AV fistula, the 14 Patients in whom central vein stenosis arose were selected for the study. A total of 28 percutaneous interventions(5 PTA and 23 stent placement) were performed, and restenosis rate and the time taken till the restenosis in de novo lesions and instant lesions were compared. All 28 cases were operated successfully. The 14 cases that received both anigioplasty and stent placement initially. (de novo lesion : 14 cases), Among the 10 cases with de novo lesion that followed up more than 1 year, 3 cases are currently undergoing hemodialysis without restenosis, and the remaining 7 cases have recurred stenosis with the mean time to restenosis of 10.9 months. In the 7 cases in whom stenosis recurred, 11 interventions were done(instent lesion: 11 cases). 4 of these were using only ballon angioplasty with 100% restenosis rate and the mean time of 3 months until restenosis. The remaining 7 cases were using both balloon angioplasty and stent placement, also with 100% restenosis rate but with the mean time of 12 months until restenosis, which was later than the group receiving only balloon angioplasty. In treating the patients with central vein stenosis, stent placement seems to be more advantageous over PTA in terms of restenosis rate and the mean duration of patency. In the case of instent lesion, inserting the stent for the second time after stenosis recurred lengthened the duration of patency compared to performing balloon angioplasty alone.

The objectives of this study were to review the concepts of rural and urban society theoretically and to search for the socio-ecological characteristics of the typical rural area, Myon, in terms of regional industrialization. The research areas were 353 Myons in 36 Guns which were sampled by stratified random sampling methed. The major findings of the study were as follows; 1) The average population of Myon, the hinterland, were 5,879 and the average households were 1,554. 2) Most of Myon had the characteristics of rural society which had over 70% of farm population rate. One Myon had 24 villages and each village held 68 households and 256 persons on the average. 3) The average area of Myon was 63.2㎢. However, the high standard deviation insinuated that there were great disparities in area between Myons. 5) The distance from Myon-office to rural center was 17Km on the average. 6) Synthetically, further research should be followed to identify whether the Myon area is suitable for a unit of rural human settlement planning area to demarcate as a self-sufficient human settlement area.

This study was conducted to evaluate and to recognize the status and the problems of working conditions, and industrial accidents for migrant workers in a group of 342 who lives in Ansan area, Kyunggi province. By the questionnaire written by 5 languages(English, Bangladesh, Indonesian, Chinese and Korean), the informations of socio-demographic factors, occupational conditions of engaged company and general & occupational health status were obtained from June, 1st to July 30th, 1998. We used the ANOVA to examine differences of working hours, days and average monthly wages between overseas industrial trainee and illegal migrant workers, and by using logistic regression, odds ratio of general risk factors for industrial accidents in migrant workers were calculated. The results obtained were as follows: 1. The major distribution of nationals were from Philippine, Indonesia, Bangladesh and China(92.1%), and the most of subjects were man(78.9%) and over high school graduate(81.9%). 2. Most migrant workers worked at small scale companies under 50 employees, and engaged in dye·textile·clothing·leather industry. The average working hours were 59.9 hours per week in overseas industrial trainee, 64.9 hours in illegal migrant worker respectively. 3. Trainees have transferred to another company for 1.89 times, and workers who have changed qualification from trainee to illegal status were 3.09 time, and illegal workers moved 2.36 times. The major portion of reason to move to another company were low salary and overdue salary. 4. Trainees, workers who have changed position from trainee to illegal status, and illegal workers knows 62.27%, 42.31%, and 20.45% in each about legal documentation for foreign industrial trainees in Korea "Regulations for protecting and managing of foreign industrial trainees in Korea " published on March 1995. Additionally, trainees and illegal workers have experienced medical examination by 52.3% and 18.2% respectively. 5. Industrial accident condition from Jun. 1st, 1997 to Dec. 31th, 1997 were as follows : in case of frequent rate, trainees and illegal workers were 30.04, 23.78 each, and 8.6%, 7.4% for industrial accident rate respectively. 6. The most common causes and types of industrial accident were inappropriate motions of body and abrasion, and body sites most vulnerable to injury were the hands and fingers. The results suggest that working status and industrial accidents of migrant workers are very poor in Korea. Therefore, occupational safety and health policy aimed at migrant workers are needed to protect the migrant workers.

흉통을 주소로 내원한 45세 남자에서 관상동맥조영술 중 비이온성 조영제에 의하여 아나필락시양 반응이 발생한 증례를 경험하였기에 보고하는 바이다. Radiocontrast agent infusion is the most common cause of non-IgE mediated anaphylactoid reaction in the modern medical procedures. The newer lower-osmolar nonionic contrast agents cause significantly lower adverse reactions than the high-osmolar ones. However, anaphylactoid reaction to nonionic contrast agent can cause life-threatening events and even death has been rarely reported. Iodixanol (Visipaque®) is a nonionic, dimeric contrast agent, which is currently used in cardiac catheterization. Here we report a case of anaphylactoid reaction to Iodixanol, a nonionic radiocontrast agent, during cardiac catheterization. A 45-year-old male patient underwent cardiac catheterization for evaluation of substernal pain during exercise. Five minutes after this contrast injection to the left coronary artery, he complained itching and dizziness. Subsequently, generalized urticaria, cyanosis and hypotension were developed. His coronary angiogram showed normal findings. He was treated with intravenous fluids, intravenous diphenhydramine, sucutaneous epinephrine and sympathomimetics and one hour later he recovered. This case suggests that anaphylactoid reaction to a radiocontrast media, iodixanol, should be considered in the list of differential diagnoses for cardiopulmonary arrest during cardiac catheterization.

The purpose of this study was to investigate the meaning of collaboration between special education teachers and inclusive class teachers. For this study, three special education teachers were sampled and observed in classroom teaching. The conclusions are as follows: First, the necessity of sharing information and communicating for overcoming the limitation from dualistic structure of inclusive education settings, and the recognition of necessity to effective teaching in inclusive class affected on the special education teachers’ motivation to collaboration. Second, special education teachers experienced some collaboration barriers such as insufficient communication in decision making of suggestion-agreement, limited collaboration and unprepared collaboration. Third, special education teachers experienced the increment in achievement of disabled students and the positive change of inclusive class teacher after collaboration with other teachers. Finally, special education teachers, through reflective introspection, found themselves insufficient collaborators who stuck to passive followership, small teaching, and prescribed just correcting answer. 본 연구는 특수학급 교사와 통합학급 교사간의 협력 경험을 탐색하면서 특수학급 교사가 경험하는 협력의 의미를 특수학급 교사의 관점에서 파악하는 데에 목적이 있다. 이를 위하여 특수학급 교사 3명을 대상으로 사례 연구를 수행하였다. 수집한 자료를 주제별로 분류하여 의미를 생성하는 과정을 통하여 다음과 같은 결론을 얻었다. 첫째, 특수학급 교사는 자발적으로 협력 동기를 형성하고 협력에 참여하였다. 통합교육 장면의 이원적 구조에서 오는 한계성을 극복하기 위한 원활한 정보 공유 및 소통의 필요성, 장애학생의 효율적인 지도를 위한 교사 간 경험의 공유와 공동대처의 필요성은 특수학급 교사의 협력동기가 되었다. 둘째, 특수학급 교사는 협력의 장애요소로 교사 간 소통 부족, 의사결정과정에의 적극적 참여 부족, 협력범위에 대한 부족한 합의, 협력을 위한 체계적인 계획 부족을 경험하였다. 셋째, 특수학급 교사는 협력 결과 장애학생의 성장과 통합학급 교사의 긍정적인 변화를 경험하였다. 넷째, 특수학급 교사는 반성적 성찰을 통하여 불완전한 협력자로서의 자기발견을 하였다.

당뇨병에서의 혈전생성 기전에 관련된 주된 요인을 관찰코져 흰쥐를 4주간 사육한 후 streptozotocin(STZ)으로 당뇨를 유발한 후 6일째에 희생하여 당뇨쥐에 있어서의 phospholipase A₂ 활성변화에 따른 조직의 과산화적 손상과 혈소판 응집능 등의 변화를 관찰한 결과는 다음과 같다. 체중증가는 STZ를 투여한 후에는 STZ 투여군에서 현저하게 감소하였다. 식이섭취에 있어 STZ injection 후, DM군은 16% 증가하였다. 식이효율은 STZ injection 후 DM군은 정상군에 비해 유의적으로 감소하였다. 혈청 중의 총 지질과산화물가는 정상군에 비해 DM군은 2.5배 높았다. HDL 중의 TBARS는 정상군에 비해 DM군은 약 1.6배 정도 높았고 LDL 중의 TBARS는 정상군에 비해 DM군에서 4.8배의 높은 증가를 보였다. 혈소판 phospholipase A₂ 활성은 DM군은 정상군에 비해 42% 증가하였다. 혈소판 cyclooxygenase 활성은 정상군에 비해 DM군이 2배 정도 높은 수준이었다. 혈소판 중의 TXA₂ 농도는 정상군과 비교하여 DM군에서 169%로 현저하게 높았고 대동백 PGI₂의 농도는 정상군에 비해 DM군은 낮은 수준을 보였으며 대동맥 PGI₂와 혈소판 TXA₂의 비는 DM군에서 정상군에 비해 55% 낮았다. 결론적으로 STZ 유발 당뇨쥐에 있어서는 혈청 지질과산화물 수준의 증가와 더불어 phospholipase A₂ 활성이 증가되었으며 따라서 cyclooxygenase가 유도하는 AA cascade 활성화에 의해 TXA₂ 생성증가 및 PGI₂/TXA₂ ratio의 감소가 관찰되었다. 이러한 결과는 당뇨병 질환에서 나타나는 동맥경화증, 심혈관계 질환 등의 여러 혈관계의 병리적 현상들이 당뇨 상태에서의 지질대사 이상으로 인한 지질과산화물의 증가와 그의 독성으로 인한 여러 혈소판 관련 인자들의 활성화와 밀접하게 연관되어 나타나는 것을 시사하는 것이라 하겠다. The relation between lipid peroxidation and thrombotic reaction were investigated in streptozotocin (STZ)-induced diabetic rats. Sprague-Dawley male rats weighing 100±10gm were randomly assigned to normal and STZ-induced diabetic group(DM). Diabetes was experimentally induced by intravenous injection of 55mg/kg of body weight of STZ in citrate buffer(pH 4.3) after 4 weeks feeding of basal diet. Animals were sacrificed at the 6th day of diabetic states. Body weight gains were lower in diabetic group after STZ injection. Serum levels of thiobarbituric acid reacting substances(TBARS) that were markedly increased in DM group compared with of normal group. TBARS levles of HDL and LDL were similar patterns to total TBARS of serum. Activities of platelet phospholipase A₂(PLA₂) were higher in diabetic group than those of normal group. Activities of platelet cyclooxygenase were 106% in DM group than normal group. Platelet thromboxane A₂(TXA₂) formation was increased in DM group than normal group. Production of aortic prostacyclin(PGI₂) was lower in diabetic group than that of normal group. PGI₂/TXA₂ ratios were decreased by 55% in DM groups than those of normal group. The present results indicate that STZ-induced diabetic rats are more sensitive to oxidative stess which leads to acceleration of lipid peroxidation and platelet aggregability. In conclusion, accelerating effect of lipid peroxidation and thrombogenesis in diabetic state is regarded to be resulted from enhancement of PLA₂ activity and arachidonic acid metabolism, inhibition of antiaggregating agent and aortic PGI₂ formation.

Pure primary medullary hemorrhage is a rare condition, which is characterized by ipsilateral hypoglossal nerve palsy and contralateral hemiparesis. The hemorrhage usually extended to medial and ventral medulla, these two characteristic signs distinguished from the classical presentation of Wallenberg's lateral medullary syndrome. A 53-years-old man was admitted with sudden onset left sides weakness and vertigo. Neurologic examination showed dysarthria, mild dysphagia, Horner syndrome of right side, spontaneous horizontal jerking nystagmus to left side and right deviation of tongue at protrusion. Pain and temperature sensation of left trunk, left extremity and right face were decreased. Brain CT scan and brain MRI revealed focal hemorrhage in the right medulla. We report a case of pure primary medullary hemorrhage with undetermined etiology.
