한창희,전성민,심상천,유병준 한국경영정보학회 2019 Asia Pacific Journal of Information Systems Vol.29 No.4

The Internet enables businesses to acquire a great deal of information, including prices in the open markets. In this study, we investigate what the value of reference price information is to a company in the market and how the company can make use of such information. Using business analytics, we were able to estimate prices of used cars for a rent-a-car company. The results show that a smart pricing information system is useful for collecting online reference price information and for estimating future prices of used cars and rental prices.

동남참게(Eriocheir japonicus)의 난황단백질 정제와 그 전구체의 합성부위 구명

To identify the histological site of synthesis of yolk protein precursor, vitellogenin, by immunocytochemical method in the freshwater crab Eriocheir japonicus, we purified the yolk protein, vitellin, from crude egg extracts, and prepared the anti-rabbit serum against vitellin. Then, the site of vitellogenin synthesis was demonstrated by immunocytochemical method with PAP(peroxidase-antiperoxidase) reaction using the rabbit antiserum against vitellin. Female specific serum protein was identified in female serum by immunoelectrophoresis and Ouchterlony's immunodiffusion test for mature male and female sera. Based on the immunoelectrophoresis and Ouchterlony's diffusion test for mature male and female sera and crude egg extracts using antiserum against vitellogenic female serum absorbed with male serum, the female specific serum protein was identified as vitellogenin, detected in female serum only. The major yolk protein, vitellin, was purified from the crude egg extracts by DEAE-cellulose ion exchange chromatography, followed by sepharose CL-4B gel filteration chromatography. The molecular weight of vitellin was estimated to be about 245,000 dalton by sepharose CL-4B gel filteration chromatography. From the results of immunological analysis for vitellin, it was found that the vitellin antiserum contained the antibody against vitellogenin. In the results of immunocytochemical reaction by PAP method with the rabbit antiserum against vitellin, the vitellogenic oocytes and the hepatopancreas of mature female showed positive PAP reaction, but not in follicle cells and previtellogenic oocytes of ovary, muscle of female and mature male hepatopancreas. Therefore, it showed that the hepatopancreas of mature female is the site of vitellogenic synthesis.

동자개, Pseudobagrus fulvidraco (Richardson)의 생식년주기

한창희,임상구 동의대학교 기초과학연구소 1998 基礎科學硏究論文集 Vol.8 No.1

To clarify the annual reproductive cycle of the banded catfish, Pseudobagrus fulvidraco(Richardson), the seasonal changes in histological aspect of gonad and liver were examined. The adult fish was captured from the upper stream of Young-San river, Chunnam in each month from May 1992 to June 1993. Based on the annual changes in GSI (gonadosomatic index), HSI (hepatosomatic index), CF (condition factor) and histological aspects of the gonads, the annual reproductive cycle were classified into 5 periods as follows: 1) Growing phase (from April to early May): The value of GSI increased and the size of oocytes in perinucleolus stage in oocytes increased gradually. Spermatogonia were developed actively from the epithelial tissues of seminiferous tubules. 2) Maturing phase (from May to early June): GSI levels increased rapidly in both sex. Oocytes at various developmental stages were observed. Appearance of active spermatogenesis were observed. 3) Mature and spawning phase (from June to August): High values of GSI remained static and oocytes accumulated significant quantitis of yolk globules. 4) Degenerating phase (from September to November): GSI levels decreased and ovaries were filled mostly with oocytes at the perinucleolus stage. Hepatic cells accumulated significant amounts of lipid droplets. 5) Resting period (from December to March) : Low values of GSI were kept and the size of oocytes at the perinucleolus stage did not increase. Spermatogenesis was not observed.

가상군(Computer-Generated Forces)의 자율지능화 방안 연구

한창희,조준호,이성기,Han, Chang-Hee,Cho, Jun-Ho,Lee, Sung-Ki 한국시뮬레이션학회 2011 한국시뮬레이션학회 논문지 Vol.20 No.1

최근 군은 과거 냉전시대와 다른 상황에 능동적으로 대처하고 비용 대비 훈련의 효과를 극대화하기 위한 방안으로 모델링 시뮬레이션 기법에 많은 관심을 보이고 있다. 이 모델링 시뮬레이션을 이용한 훈련이 효과적이기 위해서는 좀 더 사실적인 전장 환경과 전투상황을 모의해야 하는데, 최근에 이를 위해서 컴퓨터상에서 인간 행위와 부대의 집단논리를 표현하는 CGF(Computer Generated Forces)에 대한 기술 개발이 주목받고 있다. 인간 행위를 모델링하는 CGF는 자동화된 병력을 모의함으로써 적군을 모의하거나 미래 전투실험, 새로운 전투개념 개발 등 중요하면서도 다양한 역할을 수행 할 수 있다. 이번 연구에서는 CGF 가상군인의 자율지능화의 방안을 고찰해보고자 한다. 군사시뮬레이션상의 가상군인의 자율지능화의 첫걸음인 과업행위 목록의 적용을 과업행위의 기본요소인 METT+T를 기반으로 그 적용과정을 설명한다. 또한 군사모의 논리는 참 진의 이진값 표현이 외에도 '보유 무기가 충분하면 급속 공격을 빠르게 하라'와 같은 모의 규칙상에서는 군사 전문가에 의해서 결정될 수밖에 없는 '충분하다', '빠르다'와 같은 퍼지 팩트가 존재한다. 이러한 주관성이 가미된 많은 군사모의 논리를 완벽히 표현하기 위해서는 퍼지 추론을 이용하는 것이 효과적인데, 이를 이번 소부대 전투 시뮬레이션에 적용하여 보다 사실적인 모의가 가능하도록 하였다. Modeling and Simulation(M&S) technology gets an attention from various parts such as industry and military. Especially, military uses the technology to cope with a different situation from the one in the Cold War and maximize the effect of training against the cost in the new environment. In order for the training based on M&S technology to be effective, the situations of a battlefield and a combat must be more realistically simulated. For this, a technique development on Computer-Generated Forces(CGF) which represents a unit's simulation logic and a human's simulated behaviors is focused. The CGF simulating a human's behaviors can be used in representing an enemy force, experimenting behaviors in a future war, and developing a new combat idea. This paper describes a methodology to accomplish Computer-Generated Forces' autonomous intelligence. It explains the process of applying a task behavior list based on the METT+T element onto CGFs. On the other hand, in the domain knowledge of military field manual, fuzzy facts such as "fast" and "sufficient" whose real values should be decided by domain experts can be easily found. In order to efficiently implement military simulation logics involved with such subjectivity, using a fuzzy inference methodology can be effective. In this study, a fuzzy inference methodology is also applied.

英國海上保險에 있어서의 現實全損

韓昌熙 서경대학교 1990 論文集 Vol.18 No.-

Institute Insurance Clauses of England is used over the world, and Korean Supreme Court recognized the effectiveness of the choice of law clauses in it. Therefore we must understand the law and practice of English insurance. I have given focus in English marime insurance in this theme. A total loss in insurance law is one on account of which the assured is entitled to recover from the underwriter the whole of amount of his subscription. Actual total loss was formerly called an absolute total loss. The meaning of the expression actual total loss is reasonably clear on the face of it. It is obvious that in the case of actual total loss there is no point in a notice of abandonment, whereas the notice of abandonment is a condition precedent to the right of recovery for a constructive total loss, because there is by definition nothing to abandon and accordingly an actual total loss entitles the assured to claim from the whole amount of his subscription without giving such notice.

A Multi-Attribute Group Decision Procedure Considering Preference Strength

한창희,안병석 한국경영과학회 2002 한국경영과학회 학술대회논문집 Vol.2002-A No.-

This paper presents an interactive multi-attribute group decision procedure to aggregate each group member's preferences when each group member articulates his or her preference information incompletely A strength measure, an indicative for the preference strength between alternatives, is derived to support each decision maker to articulate preference information about alternatives. mathematical programing model is proposed that can establish when dominance relations preference information about utilities, attribute weights, and group member's importance weights are provided incompletely. Also, the preference relation between alternatives is to be considered in the model Considering the preference strength measure and mathematical model, we develop an interactive group decision support procedure.

생명보험에서 자살면책에 관한 연구

한창희 한국상사법학회 2013 商事法硏究 Vol.32 No.1

Life insurance contract terms provide that when the insured suicidesbeyond the free decision due to mental defection etc, the life insurer mustpay the insured money. Perhaps the chief reason why even if the suicidedefects the fortuity, the life insurer is liable for the beneficiary is theprotection of the surviving family. Life insurance practices in the mostcountries limitedly insure against the insured’s suicide similarly to Korean lifeinsurance. Recently Korean society worries about the rapid increase of the suicide,Korean suicide rate has marked the top among OECD countries. Koreangovernment has struggled to lessen the numbers of the suicide. These days Korean Insurance Research Institute has issued the researchingresult on “How the excluding period’s clause under the life insuranceimpacts on the suicide.” It concluded that the suicide rate has rapidlyincreased after the lapse of excluded period(2 years) under the life insurancecontract terms. It explains that the insureds are inclined to commit a suicideafter 2 years beginning from the concluding date of insurance contract inorder to leave insured money for surviving family. It has been widely heard that Financial Services Commission hasinternallydecided that it would prolong the excluded period from 2 years tolonger time at least. This paper aims at comparatively studying the excluded period of thesuicide, and suggesting the reform measures. The concrete suggestions are as follows. First, a plan that the scope of the suicide should be fixed to exclude thesuicide during the excluded time regardless of conscious or unconscioussuicide, can be reviewed. Second, the excluded time can be extended from current 2 years to 3years,Third, it can be researched that the suicide should be excluded all thetime. Fourth, the Korean Insurance Contract Law can be revised to explicitlyprovide the scope of the suicide. Fifth, it can be suggested that life insurance industries are able to choosethe protection scope of the suicide.
