연구목적 : 본 시험의 목적은 임상시험 시작전에 연구자들을 대상으로 PANSS Workshop을 통하여 PANSS, ESRS에 대한 국내에서의 표준화 작업을 구축하고 새로운 정신병 치료제인 리스페리돈의 효과와 안정성을 재확인하여 리스페리돈 사용에 대한 적정화를 이루는데 있다. 연구방법 : 1996년 4월부터 1996년 9월까지 국내 39개 대학병원 정신과에 입원중인 혹은 증상이 악화되어 입원하는 정신분열병 환자 377명을 대상으로 다시설 개방 연구를 시행하였다. 1주일간의 약물 배설기간을 가진후, 리스페리돈을 8주간 투여하였고, 기준점, 1주, 2주, 4주, 그리고 8주후에 평가되었다. 용량은 제1일에는 리스페리돈 1mg씩 1일 2회, 제2일에는 2mg씩 1일 2회, 제3∼7일에는 3mg씩 1일 2회 투여하였다. 이후 환자의 임상상태에 따라 임의로 증량할 수 있으며, 최대 일일 16mg을 초과하지 않도록 하였다. 추체외로 증상을 조절하기 위한 투약을 허용하였다. 임상증상 및 부작용의 평가는 PANSS(Positive and Negative Syndrome Scale), CGI(Clinical Global Impression) 그리고 ESRS(Extrapyramidal Symptom Rating Scale)을 사용하였다. 연구결과 : 377명중 343명(91%)이 8주간의 연구를 완결하였다. 치료 종결시점인 8주후 PANSS 총점수가 20% 이상 호전된 경우를 약물 반응군으로 정의할때, 약물반응군은 81.3%였다. 리스페리돈에 반응하는 예측인자로는 발병연령, 이전의 입원 횟수, 유병기간이 관련 있었다. 리스페리돈은 1주후부터 PANSS양성, 음성, 및 일반정신병리 점수상에 유의한 호전을 보여 효과가 빨랐다. CGI의 경우도 기준점에 비해 1주후부터 유의한 감소를 나타내었다. ESRS의 경우, 파킨슨 평가점수는 기준점과 비교해 투여 1주, 2주, 4주후 유의하게 증가되었다가 8주후 기준점과 차이가 없었다. Dystonia 평가점수는 1주후만 유의한 증가를 보였으며, dyskinesia 평가점수는 유의한 차이가 없었다. 혈압, 맥박수의 생명징후 및 일반 혈액학 검사, 생화학적 검사, 심전도 검사에서 유의한 변화는 없었다. 결 론 : 이상의 다시설 개방 임상 연구를 통해 리스페리돈은 정신분열병 환자에서 양성증상뿐만 아니라 음성증상 및 전반적인 증상에도 효과적인 것으로 사료된다. 보다 명확한 평가를 위해서는 다른 항정신병약물과의 이중맹검 연구가 필요할 것으로 생각되며, 또한 장기적 치료에 대한 평가도 함께 이루어져야 하겠다. Objective : The purpose of this study was to investigate the efficacy and safety of risperidone in the treatment of Korean schizophrenic patients. Method : This multicenter open study included 377 schizophrenic patients drawn from 39 university hospitals. After a wash-out period of 1 week, the schizophrenic patients were treated with risperidone for 8 weeks and evaluated at 5 points ; at baseline, and 1, 2, 4 and 8 weeks of treatment. The dose was increased from 2mg/day(1mg twice daily) to 6mg/day(3mg twice daily) during the first week and adjusted to a maximum of 16mg/day over the next 7 weeks according to the patient's clinical response. Medication to control extrapyramidal symptoms was permitted. The psychiatric and neurological status of the patients was assessed by PANSS, CGI, and ESRS scales. Results : 343(91%) of 377 patients completed the 8-week trial period. Clinical improvement, as defined by a 20% or more reduction in total PANSS score at end point, was shown by 81.3% of patients. The predictors of response to risperidone were associated older age, shorter duration of illness, fewer previous hospitalization. Risperidone had rapid onset of action ; a significant decrease of the total PANSS and three PANSS factor(positive, negative, general), and CGI was already noticed at the end of first week. For the ESRS, parkinsonism rating scores were significantly increased until week 4 comparing with baseline. Dystonia rating scores were significantly increased until week 1, and dyskinesia rating scores were not significantly changed during the study. Laboratory parameters including vital sign, EKG, hematological, and biochemical values showed no significant changes during the trial. Conclusions : This study suggests that risperidone is generally safe and effective against both the positive and negative symptoms in our group of patients.

Objective: The aim of this study was to examine the actual conditions of absence and early leave due to job stress of 4,350 workers in 83 small and medium scale industries, and its relationship to job stress factors using Korean Occupational Stress Scale-Short Form (KOSS-SF). Methods: A structured self-reported questionnaire was used to assess each respondent's Sociodemographics, job stress, experience of absence and early leave due to job stress. Seven KOSS-SF domains of job stress were used. We estimated the relation of absence and early leave due to job stress and job stress factors using logistic regression analyses. Results: Absence or early leave due to job stress occurred in 7% of male workers and 8% of female workers. Multiple regression analysis revealed a significantly positive association job stress-related absence/early leave and job demand, interpersonal conflict, organizational system, lack of rewards and occupational climate. Conclusions: Absence and early leave due to job stress is significantly attributed to organizational System and lack of reward for men, and occupational climate and organizational system for women.

중국의 미래, 중국이라는 미래

?;?;The dazzling speed of China’s recent economic growth has occasioned the rise, in some Korean circles, of the ';';G2 theory.” This theory elevates China to the status of a superpower equal in standing only to the U.S. Regarding this ascent, opinions proliferate: positive and negative prognoses about China’s future, debates on the sustainability of China’s economic growth, and divergent views on both the causes and the cures of China’s economic crisis. If John and Doris Naisbitt in China';s Megatrends articulate an optimistic view of China's future, Fault Lines on the Face of China by David Marriott and Karl Lacroix represents the school of pessimism. Opinions also diverge on the subject of sustainability for China’s economic growth over the long haul. While Mark Leonard in What does China Think? argues that China, by relying on a unique developmental model distinct from the West’s, will succeed in continuing its growth, Minqi Lee';s The Rise of China and the Demise of the World Capitalist Economy forecasts that China';s phe-nomenal development will soon founder upon the crises affecting the entire globe such as capitalist accumulation, depletion of fossil fuels, and global warming. Finally, regarding the economic crisis confronting China, Zhiwu Chen claims that development would be enhanced by a more rigorous application of American-style free market economy and democracy, while Larry H. P. Lang argues that the critical task is to seek an exit from the system of neo-imperial plunder built on the mechanisms of the exchange rate, trade, and control of raw material prices, a system which is led by the Wall Street and backed by the U.S. government. Despite such divergences, a common thread that runs through these texts is the emphasis on the contradictory ambivalence in which China finds itself today, brought out by analyses of multiple case studies and examples. The concept of contradictory ambivalence points to an inner tension generated by the simultaneous existence and adequate management of a plethora of internal problems afflicting China, and identifies this tension as precisely the force that moves China today. An attempt to gain a deeper understanding of the internal complexity of “the Chinese situation” must thus avoid an excessive interest in such questions as “the future of world supremacy” and go beyond Western universalist frames that foreground “democracy” and ';human rights.”

비집속빔을 이용한 CO_2 레이저 빔 조사강화

서정,이제훈,강희신,김정오,이문용,오상진,이규현 한국레이저가공학회 2003 한국레이저가공학회지 Vol.6 No.2

Defocused CO_2 laser beam irradiation strengthening of 60kgf/㎟ grade steel sheet was investigated to obtain the tensile strength similar to that of fully penetrated one by the focused beam. The melted line width by the defocused beam was 3∼4 times larger compared to that of the focused beam. However, the increase of tensile strength with 1 line irradiation by the defocused beam was similar to that of 2∼3 lines by the focused beam. The increase(37.6%) of bending strength with 1 line by the defocused beam was higher than the increase(12.9%) of tensile strength. Also, the effect of cooling gas to strengthening was observed.

Growth of fish is controlled by various environmental factors, including water temperature (WT). WT is also a major factor that affects the eating behavior of fish. In this study, we studied the relationship between WT and expression profiles of factors involved in appetite regulation and digestion in red spotted grouper. Fish were divided into three groups with 30 fish per group and reared for 2 weeks in a recirculating system at three different WT (natural WT, 20 °C, and 25 °C). After 2 weeks, they were sacrificed immediately after food intake (+ 0 h), 3 h after (+ 3 h), 6 h after (+ 6 h), and 3 h before being fed the next day (− 3 h). Fish samples were obtained for analysis of mRNA expression levels of cholecystokinin (CCK), leptin A (LepA), leptin B (LepB), and neuropeptide Y (NPY) in the brain, liver, and intestine. Expression of CCK and NPY mRNA was significantly higher at 25 °C compared to that at natural WT and 20 °C, but no difference was observed for leptin. This suggests that the red spotted grouper shows characteristics typical of subtropical fish and has higher levels of feeding and digestion when reared at 25 °C water temperature condition.

Objective : Our purpose of this study was to determine the clarity and consuming time of fetal surface screening in thirty-eight fetuses from 24 to 32 weeks of gestation by use of two and three-dimensional ultrasonography. Methods : From May 1998 to July 1998, we performed the fetal surface screening of the fetal face, extremities, and spine. Thirty-eight fetuses of 24-32 weeks of gestation (thirty-seven normal fetuses and one abnormal fetus) were studied by use two-dimensional (AI 5200S, 3.5-5.0MHz; Acoustic Imaging Technologic Cooperation, U.S.A.) and three-dimensional ultrasonography (Volusion 530D, 3.5-5.0 MHz ; Kretz-Medicine, Korea). On the fetal face, we evaluated both orbits, nose, lips and brow. Both hands and feet, five digits and toes should be seen in this study. We evaluated cervical spine and lumbosacral junction of the spine. Results : The maternal average age of 38 patients was 29.9 years and the average gestational age was 29.7 weeks. The results of fetal surface screening were as follows : face (both orbits 89.5%, lips 92.1%, nose 92.1%, and brow 89.5%), extremities (both hands 68.4% and feet 73.7%), and spine (cervical spine 94.7% and lumbosacral junction 97.4%) by use of two-dimensional ultrasonography. By use of three-dimensional ultrasonography, results were as follows : face (both orbits 76.3%, lips 81.6%, nose 81.6%, and brow 78.9%), extremities (both hands 76.3% and feet 78.9%), and spine (cervical spine 71.1% and lumbosacral junction 73.7%). Consuming time for two-dimensional ultrasonography were 4.7 minutes for face, 11.6 minutes for extremities, and 5.7 minutes for spine. Using three-dimensional ultrasonography results were 12.8 minutes for face, 17.9 minutes for extremities, and 11.7 minutes for spine. Average consuming time of all fetal anatomic screening was 22.0 and 42.4 minutes by use of two and three dimensional ultrasonography. In one abnormal fetus had cleft lip and polydactyly of right foot which were detected all by three-dimensional ultrasonography, but we couldn't detect the polydactyly by two-dimensional ultrasonography. Conclusion : Three-dimensional ultrasonography was more time-consuming method, but we suggested that three-dimensional ultrasonography was superior than two-dimensional ultrasonography in fetal surface screening.

Schwann cells(SCs), an important component of the peripheral nervous system, intract with nerous to mutually support growth and replication for the peripheral nerve regentation. Recently, ading SCs to the lumen of guidance channel is widely tried to improve regeneration or to make regeneration possible over otherwise irreparable gaps. however, it is not easy to isolate and multiplicate SCs as much as enough to help the axonal regeneration. For the allogeneic SCs source for tubular nerve guidance, we developed a little bit improved technique of harvesting and multiplicating SCs. by culturing dispersed dorsal root ganglia in specially designed medium with growth factors and serial processing, we repeatedlly generate relatively homogenous SC cultures. Our technique was compared with other methods of literature using immunostaining methods such as GFAP, S100, BDNF and the total SC count assessment at different time interval after primary culture.

Despite the use of aggressive local and systemic treatment including autologous stem cell transplantation in multiple myeloma, extramedullary recurrences are common and the prognosis of these patients is poor. Many novel drugs such as thalidomide, lenalidomide and bortezomib improve the response of treatment of multiple myeloma, but some reports failed to describe thalidomide has effect in extramedullary plasmacytoma. Recent data report on the successful treatment plasmacytomas with bortezomib in patients with advanced multiple myeloma. We treated 4 relapsed or refractory extramedullary plasmacytomas with bortezomib at our institution. We recognized all these extramedullary plasmacytomas decreased and showed more than partial response. This report lends support to the efficacy of bortezomib in the treatment of plasmacytoma and describes the safe use of bortezomib. Responses may, however, be of short duration. Therefore, despite our limited experience, we propose that bortezomib may be considered a therapeutic option for such patients who have risk of radiation therapy

Rocuronium의 애별투여방법이 모지내전근의 이완에 미치는 영향

Objective : There are controversies in pnmmg technique of rocuronium whether it can or can't shorten the onset time. We want to compare the effects of two different priming doses and intervals of rocuronium. Materials and Methods : After giving propofol, 50 patients were randomly assigned to 5 groups. Group I received a placebo, followed 3 min later by rocuronium 0.6 mg/kg. Priming doses and intervals of Group II, Ill, N, V were 0.06 rng/kg and 2 min, 0.12 mg/kg and 2 min, 0.06 rug/kg and 3 min, 0.12 mg/kg and 3 min, respectively. Total dose of rocuronium was 0.6mg/kg. Train of four (TOF) count or ratio and 1st twitch height of TOF (T1) were monitored with 15 secondsintervals. TOF ratio of each groups just before bolus injection, duration for TOF count to reach zero and duration for Tl to reach 95% depression after bolus injection were compared. Results : Duration for TOF count to reach zero and duration for Tl to reach 95% depression after bolus injection were decreased in priming groups compared to Group 1 (P < 0.01) In group V, significant depression of TOF ratio just before bolus injection was seen (P < 0.05). Conclusion : Priming technique with rocuronium is effective method to shorten the onset of neuromuscular block. But priming dose of rocuronium itself could cause hypoxia and aspiration in awake patients and should be used carefully. Priming dose of rocuronium 0.06 mg/kg and 2 minutes interval maybe relatively safe method.
