조수행,홍순석,신영준,박성원 한국공업화학회 2003 응용화학 Vol.7 No.1

In the development of the advanced spent fuel management process based on the molten salt technology, it is essential to choose the optimum material for the process equipment handling molten salt. As a part of assessment and application of the strutural material for the molten salt handling system, corrosion behavior of 316LN ss weld in the molten salts was investigated. In a molten salt of LiCI-Li_2O, the oxide scales of LiCrO_2 and Li_4M_0O_5 were formed at the rate of similar linear kinetics. But in the molten salt of lI-Li_2O-Li_3N, the oxide and nitride scales of Li_4M_0O_5 and M_02N were formed at the rate of simliar linear kinetics. The corrosion rate of 316 LN ss in the molten salt of LiCI-Li_2O was lower than that in the molten salt of LiCI-Li_2O-Li_3N.

In this study, the critical loading position of cement concrete pavement is evaluated using the finite element method. In the analysis the temperature gradient of the slab is considered and 18 Kips is replaced by DB 24 as a standard load. The Winkler model under a 5-slab system which is linked with 4 joints in one direction is selected as foundation. The rigid pavement is subjected to the interior and the edge loading of DB 24 located on the various positions and then the maximum major principal stresses corresponding to the loading positions are calculated. It is found that the most critical stress occurs when the 2 rear axles of DB 24 are located symmetrically with a joint in the center on the edge and is affected by temperature gradient. Also, comparing the results of DB 24 with those of single axle load, it can be inferred that there is little differences of major principal stress between them.

Background: V. vulnificus infection in found between May and October when the man who has hepatic disorder or immunity disorder eats raw shellfish and it causes the systemic symptoms such as sudden fever, chilling, shock and stupor and local skin lesions like bleb and necrosis. This disease has 46∼61% of fatality rate in spite of intensive treatment. This study conducts the examination of history, epidemic study, ingesting raw fish and bacteriologic investigation in the patients with similar clinical symptoms to the above and examines the diagnostic dorrelations. Method: It is conducted with 31 cases who admitted at emergency medical center of Chosun University Hospital from May of 1995 to September of 1998 and are suspected to have V.vulnificus infection. It analyze bacteriologic examination, the survey of residence, eating raw shellfish, hepatic disorder, alcohol drinking habits and skin lesion. Results: 1) The rate of male and female is 15.5:1 and in the age, 18 cases are in fifties, seven are in forties and six are over sixties. 2) Clinically, V.vulnificus is detected in 20 of 31 cases which is suspected to have V.vulnificus infection and it is not detected in 5 cases. Other bacteria are detected in 6 cases and they include staphylococcus aureus, pseudomonas species, β-hemolytic streptococcus and E-coil. 3) In local distribution, Kohung has 10 cases, Shinan and Mokpo have six, Haenam and Kangjin have five, Yongkwang and Muan have five, Naju and Yongam have five and Kwangju has one. 4) Eating fishes and raw shellfishes is found in 31 cases. In the kind of shellfishes, eating raw clam is 10 cases, raw thin-shelled surf calm is 8 cases, raw oyster is 5 cases and sliced raw fish is 4 cases and pickled sea foods are 4 cases. 5) The cases with hepatic disorder are 23 and 15 cases with heavy alcohol drinking Carrier are included. The cases with Diabetic Mellitus are four and those with pulmonary tuberculosis are two. Two cases have not basal diseases. 6) On the opinion of skin lesion, 20 cases show vesicular necrosis, 7 cases have dendriform erythema, 3 cases have papule and one case doesn't show clear skin lesion. Conclusion: When V.vulnificus infection is detected, it is fatal and those who have hepatic disorder or heavy alcohol drinking habit must avoid eating fishes and shellfishes raw in summer. It is important to have emergency treatment for the patient whose V.vulnificus infection is suspected. It is considered that the administration of initial antibiotics is effective by generalizing the clinical symptom, epidemic opinion and patient history even before the results of bacteriologic confirmed.

藥物의 吸收 排池에 關한 硏究(第6報) : 病態白鼠에서의 Sulpyrine 吸收에 대하여 Absorption of Sulpyrine in Pathological Rats

趙春宇,金壽億,徐成勳 慶熙大學校 1987 論文集 Vol.16 No.-

Studies on the gastrointestinal absorption of sulpyrine was examined by rats pretreated with alloxan on carbon tetrachloride(CCl_4). Gastric absorption was increased in proportion to pH addition Alloxan diabeted group was increased rather than control group but hepatic disorder group was repressed more or less. Intestinal absorption of sulpyrine by in situ recirculating perfusion was increased in alloxan diabetes group and was repressed in hepatic disorder group, too. Absorption half-life of control, alloxan diabetes and hepatic disorder groups was 54.57, 36.32 and 72.63 minutes in separate. The transmucosal fluid in the intestine of alloxan diabetic rats was abserlved to be increased but CCl_4 hepatic disorder's rats be depressed. But the rate of transmucosal fluid was not in proportion to absorption of drugs.

성덕규,조수철 대한소아청소년정신의학회 2001 소아청소년정신의학 Vol.12 No.1

베타 용혈성 A군 연구균(group A beta-hemolytic streptococcus)에 의한 류마치스성 열 이후에Sydenham무도병이 발현되는 환자 군에서 강박 증상 또는 틱 증상이 나타난다는 보고가 있은 후, A군 연구균 감염과 강박 장애 또는 틱 장애 사이의 관계가 주목받게 되었다. A군 연구균 감염 후에 강박 증상 또는 틱 증상이 유발되는 환자들은 갑작스런 발병과 극적인 증상 악화를 보이고 사춘기 이전에 발병하며 무도병 모양의 운동 및 독특한 양상의 운동 과잉 등의 신경학적 이상을 보이고 또 그 경과가 악화 및 완화를 반복하는 양상을 보인다. 이런 임상적 특징을 보이는 소아 환자 군을 PANDAS(pediatric autoimmune neuropsychiatric disorders associated with streptococcal infections)라고 부르게 되었다. 이후 현재까지 강박 장애와 틱 장애뿐 아니라 주의력 결핍/과잉운동 장애, 신경성 식욕부전증, 신체이형장애 환자들이 PANDAS 범주에 속한다는 보고들이 있어 왔다. 본 증례는 7세까지 정상적인 발달을 보이다가 A군 연구균 감염 수개일 후부터, 인지 기능, 사회성, 언어 및 의사소통에 장애를 보이고 틱 증상과 함께 얼굴과 손발에 이상 운동을 보이는 환자를 기술하였다. 이에 저자들은 본 증례가 소아기 붕괴성 장애의 양상을 보이는 PANDAS증례라고 생각되어 이를 문헌 고찰과 함께 보고함으로써, PANDAS가 틱 장애, 강박 장애, 주의력 결핍/과잉운동 장애, 신경성 식욕부전증, 그리고 신체이형장애 등의 양상을 보일 뿐 아니라 소아기 붕괴성 장애의 양상을 보일 수 있다는 사실을 보고하고자 한다. 중심단어 : A군 연구균 · PANDAS ㆍ 소아기 붕괴성 장애. After the fact that obsessive-compulsive symptoms or tic symptoms are common in Sydenham's chorea which is a sequale of rheumatic fever produced by group A beta-hemolytic streptococcus was reported, the association between group A beta-hemolytic streptococcus and a subgroup of obsessive-compulsive disorder (OCD) or tic disorder has been attentioned. This subgroup shared a unique clinical course, characterized by an abrupt onset of symptoms and/or dramatic exacerbations. And this subgroup was distinguished by pre-pubertal onset of symptoms, neurological abnormalities (chorei-form movements and a unique pattern of motoric hyperactivity) , as well as by relapsing and remitting symptom course. Acronym PANDAS (pediatric autoimmune neuropsychiatric disorders associated with streptococcal infection) was used to denote a subgroup of OCD or tic disorder patients with these clinical characteristics. Then, there was a report suggesting that PANDAS category include some of attention-deficit/hyperactivity disorder (ADHD) and were two case reports of anorexia nervosa and body dysmorphic disorder with characteristics of PANDAS. This case is a patient who developed normally until age of 7, but after pharyngeal inflammation with high fever, he showed disturbance of cognition, social relationship, and language and communication, as well as tic symtoms and abnormal movement on face, hand, and foot. We report this case with review of literatures, because we think that this case belongs to the PANDAS category. Based on this observation, we suggest that PANDAS category include some of childhood disintegrative disorder as well as OCD, tic disorder, and ADHD. KEY WORDS : Group A beta-hemolytic streptococcus PANDAS ㆍ Childhood disintegrative disorder.

Endotracheal intubation has been used widely for the maintenance of airway in the emergency patient and CPR in the acute airway obstruction patient and to treat respiratory insufficiency. Endotracheal intubation has many advantages but it may cause several complications which rate about 4% of endotracheal intubation patient. Among these complications, laryngeal granuloma is a relatively rare complication arising about 1 case per 10,000∼20,000 cases. Authors report a case of laryngeal granuloma which developed after endotracheal intubation required during emergency treatment. Case: A 55-year old female patient visited Chosun University Hospital Emergency Room complaining of dyspnea, cyanosis and sweating on Feb. 8th 1995. According to past history, she had a little obesity, dyspnea on exercise and mild hypertension. At arrival, blood pressure was 240/110mmHg, pulse rate 150 rates/min, respiratory rate 12/min, body temperature 36.5℃ and cyanosis with sweating on whole body was observed. And the mental state was semicoma. At 5 minutes after arrival, sudden respiratory arrest developed and immediate endotracheal intubation which emergency treatment was performed it was difficult to intubate endotracheally due to short neck and obesity. At 1 hour after arrival, general condition of the patient recovered well and extubation was done. The patient was transferred to internal medicine department and discharged after 12 days of medical treatment. At 2 months after discharge, the patient felt a progressive hoarseness and foreign body sensation of larynx. She was diagnosed as laryngeal granuloma at ENT department of Chosun University. She underwent the surgical operation and discharged in good health after 7 days of admission.

조채룡,이수재,장민수,김호종,정세영,노동택,김성철 동의대학교 기초과학연구소 1993 基礎科學硏究論文集 Vol.3 No.1

Concentrated solution was prepared for a sol-gel process of BaTiO₃. Barium hydroxide and Ti-isopropoxide were used as the raw materials with methanol and isopropanol as solvents. Dense ferroelectric polycrystalline BaTiO₃thin films with the perovskite structure were fabricated by spin coating of the prepared concentrated solution on a few substrates. From XRD investigation, it was confirmed that tetragonal phase of polycrystalline BaTiO₃powders are formed after heat treatment above 550℃ in air and grain-oriented BaTiO₃thin films are obtained by coating of 0.06M concentrated solution on the substrates. It was observed that surfaces of thin films deposited on the substrates by our methods were formed crack-free and uniformly. The thickness of thin film which depends the concentration of the solution was 400∼900Å for 1 time coating, which was confirmed by SEM analysis. Ceramics and thin films show dielectric constant of 4600 (at 1㎑) and capacitance 300∼800㎊ (at 1㎑) at room temperature, respectively.

Background: The present study was performed in order to identify the possible future location of the Department of Emergency Medicine and future demand for and supply of manpower through a survey of the heads of Kwangju City and Chollanam-do hospitals. The survey covered the degrees of recognition and understanding, the necessity, the future prospects, and the direction of development of the Department of Emergency Medicine. Methods: A total of 33 large-scale general hospitals were selected in county districts having more than 200 sickbeds as of November 1999. Among them, the heads of 29 hospitals responded to the survey. The survey had a total of 31 questions, including 6 questions on the status of the emergency room. Six(6) questions concerned the degree of recognition of the Department of Emergency Medicine. Six(6) questions concerned the degree of understanding of the Department of Emergency Medicine. Six(6) questions concerned the necessity for the Department of Emergency Medicine, and 7 questions concerned the future prospects and direction of development. The results of the survey were analyzed. Results: 1) As to the question of the degree of recognition, the Department of Emergency Medicine was known to all. That is, 50% of the respondents were well aware of the department, and 50% a little, Nineteen(19) respondents(65%) answered that it was convenient to have the Department of Emergency Medicine in a university hospital, among which 16 respondents(55%) answered that it was because of the rapid treatment of emergency patients. 2) As to the question of the degree of understanding, particularly, the areas of medical examination and treatment by the Department of Emergency Medicine, 15 respondents answered that it was for the treatment of patients who needed to receive emergency treatment, while 12 respondents answered that it was for the diagnosis and treatment of all patients who visited the emergency room. Only 7 respondents(24%) answered positively as to the possibility of the Department of Emergency Medicine using thrombolysis medicine. 3) All except for one respondent had a positive view on the necessity for the Department of Emergency Medicine, and all except for 3 respondents wanted to have specialized doctors in emergency medicine work at the corresponding hospital. As to the type of schedule, 10 hospitals(34%) wanted to have only night shifts, and 11 hospitals(38%) wanted to have both day and night shifts. Most hospitals needed two or more workers in the field. 4) As to the question of the direction of development, many respondents were of the opinion that the hiring of specialized doctors in emergency medicine would not be of greatly help to the finances of the hospital due to increased labor costs. It seems that improvement of the medical system to improve hospital financing is a required prerequisite for the development of the Department of Emergency Medicine. Also, 21 respondents(83%) were of the opinion that it would take a considerable amount of time to activate the Department of Emergency Medicine with respect to the future prospects of the department. Conclusion: It was shown in the present survey that the heads of hospitals in Kwangju City and Chollanam-do recognized the Department of Emergency Medicine in a positive way, but it was necessary to establish both a delivery system for emergency medicine and collaboration with and support by other medical areas for its future development. It was estimated that in the future, more than 55 doctors specializing in emergency medicine would be needed as medical manpower for the general hospitals in the districts.
