최근 국가기간 철도망의 도심지 통과시 민원 및 환경, 기존 노선과의 접속 등의 이유로 구조물 근접, 하저, 퇴적층~경암의 복합지반 등 점점 더 가혹한 현장조건에서도 터널공법의 적용이 요구되어 지고 있으며, 이들 조건에서도 안전하게 시공이 가능한 쉴드(Shield) TBM에 대한 적용이 증가하고 있다. 본 고에서는 대곡~소사 복선전철 민간투자시설사업 구간 중 한강 하저를 횡단하는 철도 쉴드(Shield) TBM 터널 설계시 주요 고려사항에 대해 기술하고자 한다. 특히, 하저구간 통과시의 고수압 조건과 한강 하류지역의 지질학적 특성으로 인한 풍화대 심도가 불규칙한 복합지반, 다수의 단층파쇄대, 퇴적층 등의 불량한 지반조건을 통과하기 위한 쉴드 TBM의 검토사항과 터널안정성 확보를 위한 주요 설계 방안을 중점적으로 다루고자 한다. Recently, despite of the harsh conditions such as adjacent structures, underwater tunnel, and complex grounds, tunnel construction has been performed inevitably in underground metropolitan area because of civil complaint, environment and connection with existing railway. Thus, it has been increasingly demanded to be constructed by Shield TBM excavation method that can be a safe way under these adverse conditions. In this paper, we would like to introduce the major considerations about the shield tunnel design for passing through under the Han-River among the BTL Project of double-track electrification in the Deagok~Sosa section. Especially, Focus on key design strategies are discussed in Shield TBM and securing the tunnel stability for passing through under the river, such as high water pressure, complexity ground, many fault fractured zone, sedimentary layer

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.

韓國企業の情報システムアウトソ-シングに關する一考察

韓光熙 韓日經商學會 1998 韓日經商論集 Vol.16 No.-

Companies large and small, through the entire industrial spectrum and around the world outsource all or part of their supply and demand chain operations. By all indications, companies continue to increase the utilization of outsourcing service vendors. By utilizing outsourcing services, companies can focus on their core business and client related activities while reducing operating costs and improving productivity. System Integration(SI) companies provide outsourced Information Technology solutions which enable to effectively process information with their trading partners in order to gain a competitive advantage. As more Korean companies are interested in this issue, they require a Oursorcing framework suitable for the circumstances of the Korean companies. This paper focuses on an establishment of Korean style of Outsorcing framework. On the basis of this study, I came to the following conclusions. To facilitate Outsourcing services in Korean companies, the following factors are necessary. The factor is: 1) Executive commitment in promoting Outsourcing 2) Clarification of the missions of Outsourcing projects 3) Promoting IT standardization 4) Organizational change and human resource development 5) Promoting outsoucing market 企業環境が急激に變化し情報システム技術が急速に發展する今日におにて,アウトソ-シングは最近企業から高い關心を受けでいる.これによってアウトソ-シングは新規需要創出の限界に來ているSI業者が不況を打開するための-つの手段として注目されるようになり,特に企業側からは費用節減のための動きによってアウトソ-シング市場はより活性化されている. したがって,アウトソ-シング市場におけるこのような變化をく把握してアウトソ-シング市場を活性化 させる必要がある. ところが,韓國企業がアウトソ-シングを實行する場合,その方案や形態がアメリカや日本などの方式をそのまま固執する必要はない.それは韓國企業の文化に合っエてないアウトソ-シングが代えて韓國企業の經營戰略に對して障害になる恐れがあるからである. したがって,韓國企業文化の慣行を生かしたアウトソ-シングの方案についてもアウトソ-シング·べンダ側 が積極的に檢討っべきである. 以上のような內容を含めて考えると,韓國企業においてアウトソ-シング市場が活性化されるにはまだ時間が必要であり,さらに情報技術的なことよりは企業經營者の認識變換や情報システム部門の要員たさが지持っている考え方の轉換のような意識的な側面がより必要である.

The purpose of this study was to examine the present state of elementary school students in extracurricular physical programs and its effect on their preference in school P.E and to provide research materials which can be used to increase teaching efficiency. For this purpose, a questionnaire was completed by 410 fifth and sixth grades in 4 different school districts(Kang-nam, Kang-buk, Kang-dong and Kang-seo)in Seoul. The questionnaire was developed on the basis of the study and adjusted for the purpose of this study. The results of the questionnaire were analyzed by SPSS. The general characteristics of the subjects of the survey were presented through frequency analysis. The correlations between the subjects' preference in the sub-fields of P.E. and the participation in the extracurricular physical program and gender were analyzed by x² verification. In addition, the t-test was executed to see the differences of preference in the sub-fields of P.E. The results were as follows. 1) The students who were not involved in extracurricular physical activity (Non-EC Group) outnumbered the student who participated in it(EC Group), In addition more boys than girls were in the extracurricular physical programs. 2) In the EC Group, boys did Taekwondo most. And it was followed by swimming soccer, basketball and Kendo. Girls also chose Taekwondo most. It preceded swimming dance, sports dance and Kindo. Unlike boys, girls rather positively participated in expressive activities like dance and sports dance. 3) With respect to the correlations between subjects' attitudes towards P.E and the participation in the extracurricular physical programs and sex, EC Group and boys showed more preference, interest and positiveness than Non-EC Group and girls(p<.001). 4) With respect to the correlations between subjects' preferences in the sub-fields of P.E. and the participation in the extracurricular physical programs and gender, first, EC Group showed more preference for gymnastics than Non EC Group(p<.05). In addition, in the sub-fields of gymnastics, boys and girls liked mat activities (37.8%) and vaulting horse activities(22.7%) most respectively(p<.01). Secondly, in the tract, there was no significant differences in the preferences between groups. Both boys and girls chose "relay" as their favorite activity. Thirdly, in the sub-field of game, soccer-related game was followed by skating and skiing. Whereas the soccer-related game was favored by both EC Group and Non-EC Group, the participation variable was significant in skiing and Taekwondo. The former was favored by EC Group. Moreover, gender affected the preference in the events of game activity. While 57.5% of the boys favored for the soccer-related game, 27.3% of the girls said "skating" was their favorite event. Preference in physical strength events differed according to participation variable as well as gender variable. Fourthly, the sub-field of expressive activity was least favoured by every group. Fifthly, in the sub-field of physical strength, "Exciting physical activity" was most popular. It showed that the participation in the extracurricular physical program and gender were analyzed as following. 5) The correlations between the elementary school student' preferences in the sub-fields of P.E and the ① Compared to The Non-EC Group, the EC Group showed significant preference in the sub-field of gymnastics, game, tract, physical strength activity. Therefore, it is proved that extracurricular physical programs can increase students' interest in these four sub-fields. ② Based on the gender variable, it was found that both boys and girls were most interested in the game activity. In case of boys, it was followed by track activity, physical strength activity, and gymnastics. In case of girls, it was followed by track activity, physical strength activity. In conclusion elementary school students' participation in extracurricular physical program affected their attitudes towards P.E. Therefore, it is essential to proceed the further research on continuity between elementary school P.E. and community sports as well as need analysis on elementary school students' P.E.

The magnetic force across the air-gap between primary and secondary part in linear induction motor is in most part constrained by bearing or linear guide. But, the existence of the normal force gives us a possibility to levitate and drive the secondary part of the linear motor stably without the bearing. Therefore, to control the normal force and the thrust force on the secondary part independently, the various methodologies have been presented. As one of the solutions, we suggest the decouple control by DC-biased multi phase input, in which the biased DC is modulated to control the normal force and the multi phase AC to control the thrust force. To guarantee the method, the distortion of the magnetic force is intensively analysed using the distributed parameter magnetic field theory for the transverse flux linear induction motor.
