Aims: Chronic Hepatitis C Virus (HCV) infection increases the risk for progressive liver disease, hepatocellular carcinoma and negatively impacts the patient’s quality of life. HCV treatment is evolving with direct acting antivirals but IFN based therapy has been the standard of care for many years and remains available in some countries. The MOSAIC study aims to characterize patients with chronic HCV infection and assess the impact of IFN-containing treatment on health-related quality of life, work related productivity and health care utilization. Methods: MOSAIC is an international prospective multicenter observational study that has been conducted in 20 countries. Consecutive patients with chronic HCV infection were enrolled and those who initiated an IFN based regimen were prospectively followed for 48 weeks. We report results from the Korean cohort Results: 100 patients were enrolled: 86 were treatment naïve and 14 were treatment experienced. 33 patients initiated an IFN based regimen: 6 patients started IFN + RBV, 26 patients started Peg-IFN + RBV, none started Peg-IFN + RBV + DAA and 1 patient received other treatment. Among the treated cohort, demographic and disease characteristics were the following: the mean age was 54.5 years; 14 patients were male. 14 had minimal or no fibrosis, 2 portal fibrosis, 3 bridging fibrosis and 6 patients suffered from cirrhosis. HCV Genotype distribution was as follows: genotype 1: 11; genotype 2: 19 and genotype 3: 3. Table 1 describes the results at baseline and changes over 4, 12 and 48 weeks and end-of-treatment (EOT) for the quality of life and work productivity outcome measures (EQ-5D-5L, HCV-PRO and WPAI). Conclusions: Results from the Korean cohort of the MOSAIC study show a moderate trend for deterioration of health-related quality of life and work productivity associated with IFN based treatment for patients with chronic HCV infection during treatment period.

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.

韓國産 미꾸리에 關한 育種·繁殖學的 硏究 : Ⅵ. Histological Changes of Pituitary Gland and Oocytes from March to May Ⅵ. 계절에 따른 암컷의 腦下垂體와 卵母細胞의 組織學的 變化

1992년 3월부터 1992년 5월까지 자연적인 채광상태에서 溫度를 유지시킨 후 채취된 미꾸리 암컷의 腦下垂體, 肝 및 卵巢 組織의 번식주기에 일어나는 미세구조의 변화를 광학 및 투과형 전자현미경을 이용하여 살펴보고, 이것들의 相互 聯關性을 알기 위하여 본 연구를 실시하였다. 본 연구에서 얻어진 결과는 다음과 같다. 성숙된 개체의 뇌하수체는 수많은 작은 분비과립과 커다란 분비구 및 불규칙한 형태의 과립들이 관찰되었다. 핵소체가 핵막 주변에 위치헤 있는 후기 단계(LMO)의 난모세포가 난황이 축적되는 성숙초기 단계(EMO)의 난모세포로 변형되는 시기를 난황의 형성이 개시되는 시기로 본다. 난모세포가 성장함에 따라 핵소체의 크기와 난황과립의 수가 증가하게 된다. 난황과립은 결정상의 과립으로 난세포질에 치밀하지 않은 상태로 축적된다. 성숙초기(EMO) 및 말기단계(LMO)에 난소는 커지고 투명하며 과립형태로서 색깔이 연노란색을 나타낸다. 따라서 난 내부를 쉽게 관찰할 수 있다. 방사대(ZR)는 성숙초기단계(EMO)에 단층으로부터 입방형태로 변화된다. 과립막 세포와 난모세포로 부터 유래된 미세융모는 난황형성이 진행되는 동안에 성장하게 되며, 방사대의 pore canals의 구멍을 통해서 서로 연결되어 있다. 따라서 외부로부터 물질의 이동이 있게 된다. 난모세포가 완전하게 성숙되어 방사대가 단단해 지면 미세융모는 그 기능이 상실된다. This study was undertaken to understand the development stages of pituitary gland, liver and ovary of Korean loach(Misgurnus anguillicaudatus) under natural circumstances from March to May 1922. Expecially, the light microscopic and ultrastructural changes of ooplasm and follicular membranes of oocytes, were observed by light and transmission electron microscope during the reproductive cycle. In pituitary gland of mature individuals, there were observed a number of secretory granules,large globules, and irregular masses.The vitellogenic phase began as these late perinucleolus oocytes became transformed into early maturing oocytes through the accumulation of yolk. The size of the nucleoli and number of the yolk granules increased as the oocyte growed. Yolk granules were loosely deposited in the oocyte as crystalline granules. Due to the presence of early and late maturing oocytes, their ovaries were enlarged transparent, granular and yellowish in color. Zona radiata change a squamous into cuboid shape in EMO stage. Microvilli from the granulosa cells and from the oocyte grow and make contact with each other in the pore canals of the zona radiata during vitellogenesis, but are withdrawn as the zona radiata becomes more compact during oocyte maturation.

It is critical that the accurate anatomy of the facial nerve IS known for uncomplicated successful facial surgery. Such an operation is hazardous because of the intimate relationship between the facial nerve and the expressional muscles. It is hoped that such basic information will be helpful to those who treat conditions involving the facial region. In order to define the detail of this relationship, many studies have been undertaken on dissected adult specimens. This study was based on Korean fetus and stillborn infant cadaveric dissections, and describes anatomical variations of the peripheral branches of the facial nerve that pose a potential danger in a number of surgical procedure on the face. The branching patterns were classified into six types: the frequencies of occurrence were: type I, 4.9%; type II, 24.4%; type III, 34.1%; type IV, 19.5%; type V, 12.2%; and type VI, 4.9%. Types II, III and IV together accounted for almost 80% of the specimens. In the discussion we compare the results of the present study with those of others and try to clarify the anatomical characteristics of the facial nerve in infants, which demand that special attention be paid to the avoidance of injuries during facial surgery.

Recently many Microwave devices have been newly developed as the demands for mobile communication and satellite broadcasting have been increased. Microwave dielectrics can be use in dielectric resonator, duplexer filter, VCO, GPS antenna and so on. The dielectric properties required for such application are high dielectric constant(ε_r), high Q value and low temperature coefficient of resonant frequency(τ_f). These requirement correspond to necessities for size reduction, excellent frequency selectivity, good temperature stability of devices. This study was focussed on the improvement and understanding for low-temperature sinterbility and microwave dielectric properties in LiNb_3O_8 compositions. The main topics of this study was the relationship between sinter behavior and microwave dielectric properties on LiNb_3O_8 system. As a result, the dielectric constant and Q×f_0 increased linearly with increase in the sinter density. The dielectric constant is about 34 and the Q×f_0 at a microwave frequencies is over 58000.

In this paper we introduce a solution to improve the unfairness problem and to remove the waste of bandwidth in the distributed queue dual bus system. This solution requires only a minor modification of the current protocol and further shows no bandwidth wastes when we try to resolve the unfairness problem occurred in current DQDB protocol. There has been many problem in DQDB system in terms of fairness of sending message in each node. In order to solve this problem, Bandwidth Balancing technic and proportional assignment technic have been introduced. It is, however, to note that the waste of bandwidth problem is still existing in those technics, even though there has been significant improvement as to the fairness problem. In this paper we introduce a new solution to remove the waste of bandwidth problem while we are still obtaining the improved fairness of the network. By following this new solution, the simulation result shows higher throughput and lower message delay than previously proposed technics.

This study set out to analyze the general leadership type of Taekwondo instructors and to investigate the relations between their leadership type and sports weness. The population was the elementary(fourth graders or higher graders), middle, and high school students attending the Taekwondo gyms registered in Gyeonngi Province in 2007. The proportionate stratified sampling was applied, and total 449 were chosen, who were asked to fill out a questionnaire. The questionnaire consisted of the items regarding the characteristics of Taekwondo practice, criteria of leadership types, and sports weness. The statistics techniques used to analyze the data included reliability analysis, frequency analysis, independent samples t-test, one-way ANOVA, correlation analysis, and multiple regression analysis. The research design and data treatment results were reflected in the data interpretation and led to the following findings: First, the individual characteristics of the Taekwondo students were investigated. As a result, the autocratic leadership was most perceived by the high school students, who were followed by middle and elementary school students. Those who practiced Taekwondo more than one year and obtained the Class 1 or higher perceived the positive leadership most, which was followed by training instruction, social, democratic, and autocratic leadership. Meanwhile, those who practiced Taekwondo less than one year and obtained the Class(Dan) 1 or lower perceived the training instruction style most, which was followed by the positive, democratic, social, and autocratic style. That is, there were differences of the students' perception of the instructors' leadership according to their individual characteristics. Second, there were no significant differences in their sports weness according to the practice period and class but there were significant differences according to school. The students' individual characteristics led to the partial differences in sports weness. Third, the relations between the leadership type and sports weness were examined. As a result, there were significant differences among the democratic, social and positive style of the five subfactors of leadership type in terms of life, which implied the partial influences on sports weness. There were significant differences in all the subfactors in terms of practice, which was translated into the positive impacts on sports weness.
