The logistics industry in Korea plays a major role in the national economy development and to make decision nation and industrial competitiveness, This study attempts to examine the economic impacts of the logistics industry using an inter-industry analysis, Specially, the study investigates production-inducting effect, value added inducing effect, and employment-inducing effect of the logistics industry based on demand-driven model. Moreover, the study deals with supply shortage effect and sectoral price effect by using supply-driven model and leontief price model, respectively, which have been rarely used because of their complications involved in computaiton. These analyses pay particular and close attention to the distribution industry by taking it as exogenous rather than endogenous. Some interesting findings emerge from the study. First, the production of 1.0 won in the logistics industry induces the production of 0.5104 won and the value-added of 0.1722 won in other industries. Second, the production of 1.0 billion won in the logistics industry causes the employment of 2.554 persons in other industries. Third, the supply shortage of 1.0 won in the logistics industry disables other industries to produce 0.9387 won. Finally, an increase of 10% in price level of the logistics industry raises the overall price level by 0.0276%.

Backgrounds and Objectives: Vascular dementia is a group of dementing disoders arising from various stroke syndrome. Among these. subcortical ischemic vascular dementia (SIVD) is regarded as a relatively distinct clinical entity. However, MRI patterns of SIVD are not homogenous. In some patients, lacunes are dominant, and in others, subcortical white matter changes are. This study was designed to compare risk factor profiles between SIVD with and without multiple lacunes. Methods: We divided 47 subjects (22 males, mean age. 68 years) recruited from VADAPET (Multicenter Trial For Evaluation Of The Changes In the PET Images Of Subcortical Vascular Dementia Patient) study into two groups one with more than 5 lacunes in deep gray matter (lacune group) and the other with 5 or less(non-lacune group) Clinical characteristics and laboratory findings of two groups were compared. Results: Nineteen of 47 patients (40%) belonged to the lacune group. The lacune and non-lacune groups d d not differ in the following variables: age, hypertension, diabetes mellitus, hyperlipidemia heart disease, history of stroke or TIA, history of trauma or major surgery, family history of hypertension stroke, or dementia, age at diagnosis of dementia, body mass index, white blood cell count, ESR, CRP, fibrinogen, hemoglobin A1C, total cholesterol. LDL cholesterol creatinine, proteinuria, glucosuria, and microhematuria. However, male sex, smoking alcohol. hemoglobin, and HDL cholesterol were possibly associated more with lacune group SIVD than with non-lacune group (p<0 1) Multivariate analyses revealed that smoking, hemoglobin, and HDL cholesterol were independent predictors of SIVD with multiple lacunes Conclusion: Our study suggests that SIVD with multiple lacunes may be significantly different in smoking habits hemoglobin, and HDL cholesterol from SIVD without multiple lacunes.

목 적: 기존치료에 반응하지 않는 다발성 간전이를 동반한 대장암 환자에서 방사선치료와 병합한 수지상세포 면역 치료의 독성과 반응도를 조사하였다. 대상 및 방법: 2004년 5월부터 2006년 11월까지 다발성 간전이가 동반된 대장암 환자들 중에서 항암화학 요법에 반응하지 않은 환자 중 지원자를 대상으로 연구를 시행하였다. 본 임상 시험에 대하여 동아대학교병원과 부산대학교병원의 임상윤리심의위원회의 허가를 획득하였고, 동의서에 서명한 환자들을 임상 시험의 대상으로 등록하였다. 환자의 말초 혈액으로부터 수지상세포를 추출하여 배양하였다. 임상시험 일자에 맞추어서 6×106개의 수지상세포를 바이알(0.5 ml)에 넣어서 디씨백/아이알 주사를 만들었다. 수지상세포 면역치료는 2주 간격으로 간전이암조직에 3회 주사하고, 5주에 내약성 평가를 하였다. 내약성 평가를 통과한 환자에게는 8주에 4번째 수지상세포 면 역치료를 하였다. 병의 악화가 없거나 임상시험에 대한 환자의 동의 철회가 없는 경우에는 5, 6번째 수지상세포면역치료를 각각 12, 16주에 시행하였다. 방사선치료는 수지상세포 면역치료를 주사할 간전이암 부위에 주사하기 전일 및 당일에 4 Gy씩을 조사하였다. 내약성 평가는 3×106개의 수지상세포로부터 시작하여, 12×106개의 수지상세포까지 시행하였다. 내약성 평가의 최대 내성 용량으로 추가 임상시험을 하였다. 수지상세포 면역치료 주사를 맞은 모든 환자들에서 안전성 평가를 하였다. 4회 이상 주사를 맞은 환자들을 대상으로 10주에 치료 반응을 평가하여 유효성을 조사하였다. 결 과: 임상시험에 등록한 24명 중 22명에서 수지상세포 면역치료를 시행하였다. 내성약 평가에는 14명이 등록하여 11명에서 평가를 완료하였다. 시험약과의 관련성이 있을 것으로 생각되는 grade 3 이상의 약물반응으로 인한 이상반응은 없었다. 12×106개의 수지상세포를 내성용량으로 확인하였고, 내성용량인 12×106개 수지상세포 면역치료를 이용하여 8명에서 추가로 시험을 하였다. 치료에 대한 환자들의 내성은 양호하였고, grade 3을 초과하는 치명적인 부작용은 발생되지 않았다. 4회 이상의 수지상세포 면역치료 주사를 받은 환자가 17명이었고, 이 중의15명에서는 종양의 반응도 평가가 이루어졌다. 본 연구의 목적은 안전성 평가이지만, 면역치료의 유효성 평가를 위해, 방사선치료와 수지상세포 면역치료 주사가 시행된 부위 외의 간전이암에서 반응도를 조사 하였다. 면역치료의 반응은 평가가 이루어진 환자들에서 정지성 병변이 4명, 진행성 병변이 11명 이었다. 결 론: 수지상세포 면역치료와 병행한 방사선치료는 이론적으로 국소 및 전신 제어에 상승효과가 있을 것으로 기대할 수 있다. 하지만 기존 치료에 반응하지 않는 매우 진행된 직장암 환자들을 대상으로 한 본 연구에서는 방사선 치료와 병합한 수지상세포 면역치료로 인한 심각한 부작용의 발생은 없었다는 결과와 4예에서의 정지성 병변의 관찰을 보고한다. 수지상세포의 최대 투여 용량, 적절한 투여 방법, 적절한 방사선의 양, 방사선과 수지상 세포의적절한 투여 간격 등에 관한 추가 연구를 통하여, 향후 제 2상, 3상 시험으로서의 진행 여부에 긍정적인 결과를얻을 수 있다고 판단한다. Purpose: To assess the toxicity and tumor response induced by DCVac/IRⓇ dendritic cell (DC) immunotherapy combined with irradiation for refractory colorectal cancer patients with multiple liver metastases. Materials and Methods: Between May 2004 and November 2006, applicants from a pool of refractory colorectal cancer patients with multiple liver metastases were enrolled. The patients were registered after having signed the informed consent form, which had been approved by the Institutional Review Board from the Dong-A University and Busan National University Hospital. DCs were obtained from peripheral blood of each patient, and then cultured in vitro. A total of 6×106 DCs were packed into a vial (DCVac/IRⓇ, 0.5 ml) at the convenience of each patient’s schedule. On the day before and on the day of each vaccination, each patient received a 4 Gy radiation dose to the target tumor. On the day of vaccination, the indicated dose of autologous DCs was injected into the irradiated tumor using ultrasound-guided needle injection procedures. A total of four vaccinations were scheduled at three 2-week intervals and one 4 week interval at the Dong-A University and Busan National University Hospital. If the tumor status was deemed to be stable or responding to therapy, an additional vaccination dose or two was approved at 4 week intervals beyond the fourth immunization. A tolerance test for DCs was conducted by injecting a range of doses (3×106 to 12×106 DCs) after the 3rd injection. Moreover, the maximal tolerable dose was applied to additional patients. Treatment safety was evaluated in all patients who had at least one injection. Treatment feasibility was evaluated by the 10th week by assessing the response of patients having at least 4 injections. For systemic toxicities, the evaluation was performed using the National Cancer Institute Common Toxicity Criteria, whereas adverse effects were recorded using common WHO toxicity criteria. Results: Of the 24 registered patients, 22 received the DCs injections. Moreover, of the 14 patients that applied for the tolerance test, only 11 patients completed it because 3 patients withdrew their testing agreement. A grade 3 or more side effect, which was possibly related to the DC injection, did not occur in additional patients. The 12×106 DC injection was identified as the maximum tolerable dose, and was then injected in an additional 8 patients. Patients tolerated the injection fairly well, with no fatal side effects. In order to assess the feasibility of DC immunotherapy, the response was evaluated in other hepatic lesions outside of the targeted hepatic lesion. The response evaluation was performed in 15 of the 17 patients who received at least 4 injections. Stable and progressive disease was found in 4 and 11 patients, respectively. Conclusion: The DC-based immunotherapy and radiotherapy is theoretically synergistic for the local control and systemic control. The DCVac/IRⓇ immunotherapy combined with irradiation was tolerable and safe in the evaluated cases of refractory colorectal cancer with multiple liver metastases. Future work should include well designed a phase II clinical trials

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.

A CAD system used in current industry is very various, and is each different in form establishing in a design, interpretation, processing part according to a characteristic of program to need in a company and is on a distribution. It is necessary for to try do an analysis on data exchange between each CAD System in this misgovernment. Let's look into a car, a ship, an aspect of a CAD System using in a representative enterprise of an airplane field. Because a customer enterprise is spending an expensive program to have a great deal of merits in a customer enterprise It will be going to match sub vendors in a program of a customer enterprise, but it draws sub vendors and cannot become a lot of assistances. Therefore, it is the trend that sub enterprises convert the Data which used each other program, and exchange information. It will be heard in various demands and CAD technology to change suddenly, data exchange with an enterprise of a consumer by production, and before a great deal of engineering changes are asked. A great deal of study is necessary on data exchange it is the conversation that a lot of enterprise is mutual, and to be able to play.
電力系統電壓 및 無效電力潮流의 最適制御에 관한 計算 앨고리즘
韓萬春,鄭銅元 연세대학교 산업기술연구소 1982 논문집 Vol.14 No.1
This paper presents a new optimizing computational algorithm for the on-line control of system voltage and reactive power flow to minimize power transmission losses. The power transmission losses are minimized by the Search method while satisfying the constrained system voltage conditions. The results were shown much more efficiently compared with the conventional method when the computer program was developed using this alogrithm and applied to the model system.
Hegel 最初의 體系 : Jena 時代 Hegel에 關한 硏究 Eine Untersuchung des Hegels Denkens in Jenaer Zeit
韓東遠 新羅大學校 1983 論文集 Vol.15 No.-
Die Erforschung der Jenaer Periode Hegels wurde lange Zeit durch unzureichend edierte texte und fehlerhafte Datierungen behindert. Rosenkranz hatte die Manuskripte, die eigentlich aus Hegels Jenaer Aeit stammen, in dessen Frankfurter Zeit verlegt. So war ein neuer Ansatz Hegels im Jahre 1801/02 gar nicht erkennbar. Ehrenberg und Link setzen das Manuskript “Logik Metaphsik Naturphilosophie” auf 1801/02 an. So wurden dadurch die entwickungsgeschichtliche Betrachtung der Abfolge der damalign Systementwurfe verwirrt. seit der neuen Datierung der “Logik Metaphysik Naturphilosophie” auf 1804/05 wird die philosophische Entwicklung Hegels in dieser Zeit erforscht. In der vorliegende Arbeit habe Ich mir eine dreifache Aufgabe gestellt. 1) Hegels fruhe Jenaer Zeit ist als eigene Periode in der Entwickungsgeshiichte seines Denkens zu betrachten. In dieser Zeit hat Hegel eine Systemkonzeption ausgearbeitet, die sich vom spateren System in wesentlichen Punkten unterscheidet. die erste Voraussetzung fur eine Interpretation dieser Systemkonzeption ist darin zu sehen, dass die Eigen-standigkeit der fruhen Systementwurfe deutlicher erkannt und dieser nicht mehr an der reifen Ausgestaltung des Systms seit der “Phanomenologie des Geistes” gemessen wurden. 2) Hier entsteht freiliche die Notwendigkeit, Hegels Verhaltnis zu Schelling am Beginn der Jenaer Periode neu zu bestimmen. Mit dem Uberrgang von Frankfurt nach Jena sah Hegel seine Aufgabe in der Systembildung, die uber die Position der Jugendschriften hinausfuhrt. hegel muss zu der Einsicht gekommen sein, dass die theologisch politischen Uberlegung aus sich heraus nicht die Entzweiungen und Gegensatze aufzuheben vermogen. Die Formulierung, die Hegel im Brief an Schelling gibt, ist: “Das Ideal des Jungling-salter musste sich zur Reflexionsform, in ein System zuglei verwandeln.” Dieses System ist die Aufgabe, die Hegel sich fur seine Mannesjahre stellt. Gemeinsam mit Schelling nimmt Hegel die Entwicklung eines umfassenden systematischen Aufrisses. Dies geschieht auf Grundlage der systematischen Arbeit Schellings. Hegel entwickelt eine Systemskizze in der “Differenzschrift”. Man darf aber nicht ubersehen, dass diese Skizze des Systems der Philosophie mit schellingschen nicht einf ach identisch war, sondern Hegels eigenen Auffassungen entsprach. Die Zusammenarbeit beider kann nicht als einseitige Abhangigkeit Hegels verstanden werden. 3) Hegels fruhe System soll nicht-wie Kimmerle-von “Logik Metaphysik Naturphilosophie (1804)”, sondern von “Differenzschrift” redonstruiert werden. Ich bin bezweifelt worden, dass die ausgearbeite Logik von 1804 als Quelle fur die Logik der erstenJenaer Jahre benutzt werden kann. Eine Systemskizze im “Naturrechtsaufsatz” von 1802 ist schon gegenuber der Systemkonzeption in der “Differenzschrift”. Ich vertrete die Stelle auf, die die Systemskizze im “Naturrechtsaufsatz” und diejenige in der “Differenzschrift” qualitative differenz haben. Ich habe es hier versucht, ohne den Vorgiff auf 1804 die fruhere Logik aus der “Differenzschrift” zu redonstruieren. Aber die genauere inhaltliche Darstellung des fruhen Systems sollte diese Wandlung, die fur die Hegelforschung immer ratselhaft geblieben war, besser verstandlichen machen.

Because strong wind is one of the few forces that, although considered in container crane design, still cause significant damage, a container crane was tested to investigate wind load characteristic in uniform flows. So, this study measured an external point pressure at the each members of a container crane according to a wind direction and a shape of members in a wind-tunnel test. The result of this test was compared to those of computation fluid dynamics using a CFX 10. The scale of a container crane model for wind tunnel test applied similarity scales to consider the size of the wind tunnel test section and the boundary condition for CFD is like wind tunnel test.
