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.

GA를 적용한 모의 UAV의 자율착륙 테스트베드 구축

한창희,Han, Changhee 한국시뮬레이션학회 2019 한국시뮬레이션학회 논문지 Vol.28 No.1

In case of unmanned aerial vehicles used in modern society, there has been a problem where a human operator should be still needed to control the UAV because of a lower level of autonomy. In this paper, genetic algorithm is selected as a methodology for the autonomy accomplishment and then we verify a possibility of UAV autonomy by applying the GA. The landing is one of the important classical tasks on aerial vehicle and the lunar Landing is one of the most historical events. Autonomy possibility of computer-simulated UAV is verified by landing autonomy method of a falling body equipped with a propulsion system similar to the lunar Lander. When applying the GA, the genom is encoded only with 4 actions (left-turn, right-turn, thrust, and free-fall) and applied onto the falling body, Then we applied the major operations of GA and achieved a success experiment. A major contribution is to construct a simulated UAV where an autonomy of UAV can be accomplished while minimizing the sensor dependency. Also we implemented a test-bed where the possibility of autonomy accomplishment by applying the GA can be verified.

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.

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.

징거미새우, Macrobrachium nipponense(De Haan)의 생식소성숙 제어에 미치는 광주기와 안병의 X-organ에 관한 연구

한창희,김대중,HAM Chang-Hee,KIM Dae-Jung 한국수산과학회 1993 한국수산과학회지 Vol.26 No.1

To clarify the relations between photoperiodism and x-organ of eyestalks to the control of gonadal maturation in a freshwater prawn, Macrobrachium nipponense, the present investigation was performed with following examinations: 1) the influence of water temperature and daylength on the control of gonadal maturation, 2) the effect of eyestalk ablation on the gonadal maturation, 3) the seasonal variation of histology of MEX-organ (medulla externa X-organ) in the eyestalk. In previtellogenesis period (December${\sim}$March) and vitellogenesis period (April${\sim}$May), gonadal maturation was considerablely influnced by water temperature. In these periods, GSI increased and gonads were matured with water temperature rising without regard to photoperiod conditions (12L/12D and 15L/9D). In spawning period (June${\sim}$August), however, gonadal maturation was influenced by photoperiod condition. While high value of GSI was kept at long photoperiod regime (15L/9D), GSI was decreased at short photoperiod regime (12L/12D). In resting period (September${\sim}$November), no rematuration was occurred at all the experimental regimes combinated with water temperatures ($16^{\circ}C,\;22^{\circ}C,\;28^{\circ}C$) and photoperiod (12L/12D, 15L/9D). Effect of X-organ which inhibite the gonadal maturation was stronger in resting period than that in previtellogenesis and ealy spawning periods by observations on the effectiveness of eyestalk ablation on the gonadal maturation. In MEX-organ of eyestalk, the number of neurosecretory cells of which size was over $20{\mu}m$ in diameter varied according to the reproductive cycle. The number of cells increased $77{\pm}12$ in resting period, and decreased $55{\pm}7$ in vitellogenesis period. Volume of Bellonci's organ, however, increased in vitellogenesis period in comparison with that in resting period.
