Scrub typhus, caused by Orientia tsutsugamushi , is an acute febrile illness. Characteristics of tsutsugamushi disease are fever, rash and eschar. However, severe complications might rarely occur, such as acute fulminant myocarditis caused by scrub typhus. Thus, there are few reports of recovery from seriously complicated cases. We report on an adult male with scrub typhus complicated with acute fulminant myocarditis with no previous comorbid illness who recovered successfully with proper treatment including antibiotics, ventilator support, percutaneous cardiopulmonary support, and continuous renal replacement therapy.

Kenneth MacMillan can be portrayed such a good choreographer who has a sense of discribing the fact' realistically. He has made 40 years of his career focused on presenting our daily life that we had, are having, and will have, and believed the ballet could do that. His belief also had an influence on non-ballet genres such as literature, dramas, and movies. On the other hand inspiration, dramatic eliments and story-telling which all stem from non-ballet genres can be found in his works. These days he is one of choreographers who have the most pioneering spirit and put enormous efforts in studying other areas. His works have fully proved the possibility that the general area of the ballet - commonly called classical or authentic area - can be broadened in ballet's themes and choreographic methods. Seymour one's said "Kenneth MacMillan was a lebel. He stirred up the system with such a dramatic story refrecting the dark side of human nature." which summarizes MacMillan's work well. Mainly, MacMillan's choreography is a 'narrative ballet' informality and, is dealing with death and sex' in theme. In addition, it should not be overlooked that his work is absolutely creative.

본 연구에서는 감마선으로 유도된 돌연변이체들에서 공통으로 발현되는 방사선 관련 유전자들의 발현을 연구하기 위하여, B. lentimorbus WJ5의 방사선 유도 돌연변이체에서 발현되는 유전자를 DNA microarray로 동시에 탐색하였다. DNA microarray는 B. lentimorbus WJ5 genome을 무작위로 절단하여 2,000단편으로 구성하였으며, 감마선 (^(60)Co)으로 유도된 7돌연변이체의 발현을 정량적으로 관찰하였다. 클러스터 분석결과 발현된 408 유전자 중 27개가 감마선 유도 돌연변이체 모두에서 유의하게 발현이 증가되었다. 특히, 복구(mutL, mutM)에너지 대사 (acsA, sdhB, p하, yhjB, citB), protease(npr), 산화자극에 대한 환원 (HMM)관련 유전자들이 동시에 증가되었다. 이는 감마선 유도 돌연변이체들에서 자발적인 직/간접 복구 관련 유전자의 발현 증가는 방사선 노출 직후 보이는 stress response와는 다른 현상임을 나타내는 것으로 생각된다. To study the radiation related gene expression in mutants of Bacillus lentimorbus WJ5 induced by gamm radiation, the simultaneous gene expression was analyzed by DNA microarray. We constructed DNA chips including two thousand randomly digested genome spots of B. lentimorbus WJ5 and compared its quantitative aspect with seven mutants induced by gamma radiation (^(60)Co). From the cluster analysis of gene expression pattern, totally 408 genes were expressed and 27 genes were significantly upregulated by the gamma radiation in all mutants. Especially, genes involved in repair (mutL, mutM), energy metabolism (acsA, sdhB, pgk, yhjB, citB), protease (npr), and reduction response to oxidative stress (HMM) were simultaneously upregulated. It seems that the induction of the direct and/or indirect repair related genes in mutants induced by gamma radiation could be remarkably different from the adaptive responses against acute exposure to radiation.

This paper introduces an experimental study for the noise reduction of a ventilating fan system. For the purpose of noise reduction of it, an absorptive duct silencer filled with a glass fiber has been conventionally utilized. However, a glass fiber has some disadvantages like hygiene and secondary pollution problems. In order to overcome these problems, in this paper, a perforated duct silencer has been applied to the ventilating fan system. For the designing of a perforated duct silencer, the transmission losses for various perforated panel systems are measured and compared with their sound absorption performances.

This paper presents evolutionary computations to solve the problems of economic load dispatch with piecewise quadratic cost functions. Genetic algorithms (GAs), evolutionary programming (EP) and evolution strategies (ESs) are applied to the ELD problems. To improve these methods in nonlinear optimization problems, two hybrid optimization methods exploiting the advantages of each evolutionary computations are developed. Optimization methods combining GA with ES, and EP with ES are tested in the ELD problem with piecewise quadratic cost functions. Case studies illustrate the superiority of the proposed methods to existing numerical methods.

The present study was intended to reveal the relationships between the severity of obesity and various risk factors for coronary heart disease. The studs subjects were 1.838 urban inhabitants (male: 962. female: 876) who went through a general health check-up during the period between January through December. 2001. The degree of obesity was estimated by BMI and its relation to coronary heart disease risk factors were investigated. With respect to the severity of obesity. the mean systolic and diastolic blood pressure. TC. LDL-C. TG and AI increased significantly. but HDL-C showed a reversed pattern. with a higher severity. On the other hand. no difference was found in FBS. The severity of obesity was directly correlated with SBP. DBP. TC. LDL-C. TG and AI. Multivariate logistic regression analysis showed that the risk factors relevant to the severity of obesity were sex. DBP and TG. The odds ratio was 2.3 times higher in women than in men. and DBP and TG were 3.8 and 1.8 times higher in the obesity group than in the normal weight group. respectively. In conclusion. blood pressure. TC. LDL-C. TG. and AI significantly increase. and HDL-C decreases in proportion to the severity of obesity. The maintenance of desirable body weight should be a target for intervention with the idea of coronary heart disease prevention.

This study aims to assess the disputes on Parcel boundaries and present the direction of boundary demarcation by means of investigating and analyzing the judicial fast·s related to the boundary disputes in Korea. This study is limited to the cases made by the Supreme Court and the Constitutional Court. 1250 cases are collected in the web site of Ministry of Legislation and analyzed in relation with boundary disputes to show dispute assessment and a methodology for boundary establishment. To identify the main reasons for the occurrence of the disputes, an analysis of the cases of boundary disputes that can be divided into civil, criminal and special cases has been taken and the result shows that the boundaries registered on cadastral maps contain considerable problems, the boundaries on the maps do not play its role as legal boundaries and the boundaries on the maps has not been considered in the procedures of criminal and special lawsuits as the precedent cases show, Therefore, on the basis of investigated and analyzed results, the proposed methodologies for establishing parcel boundaries are identified as follows:firstly change of the legal boundary to the ground boundary, secondly establishment of a special organization for the settlement of boundary disputes, and lastly promotion of a cadastral resurveying project by the fusion of real occupancy boundary with the map boundary.

This paper presents the new methods of fault diagnosis through multiple alarm processing of relays and circuit breakers in local substation using probabilistic neural networks. When faults occur in power system an operator in the control room diagnoses the fault and starts recovering the faulted power system after analyzing the alarm information of relays and circuit breakers. However, estimation of fault section is difficult, especially for the cases of maloperation or misoperation of relays or circuit breakers and multiple faults at the same time. To show the possibility of the proposed method, it is compared back-propagation teaming method through simulation in simulation panel for Sinyangsan substation system and case study shows the possibility of probabilistic neural networks method for the fault diagnosis.
