Sodium chlorate/hydrochloric acid mixtures were used to chlorinate activated arenes and the $\alpha$-position of ketones. This chlorination method was used to produce selectively mono-, di-, and trichlorinated compounds by controlling the molarity of sodium chlorate. This reagent proved to be much more efficient and easier to handle than chlorine gas.

Multi-agent robot system is the system which executes by cooperating with each robots and controlling several robots. Capability and function of each robot must be considered for cooperation behavior. Furthermore, it is necessary to analyze the given environment and to replace complex task with some simple tasks. Analysis of the given environment and role assignment for the given tasks are composed of discret event. In this paper, the hierarchical controller for multi-agent robot system using the petri-net state diagram is proposed. The proposed modeling method is implemented for soccer robot system. The effectiveness of proposed modeling method is shown through experiment.

A one site chemotherapy agent-diffusion model is proposed which accounts for diffusion of chemotherapy agent, normal and cancer cells. It is shown that, by controlling the initial conditions, consequently an initial dose of the chemotherapy agent, the system is guaranteed to evolute towards a target equilibrium state. Or, growth of the normal cells occurs against decay of the cancer cells. Effects of diffusion of chemotherapy-agent and cells are investigated through numerical computations of the concentrations in square and triangular cancer sites.

This study is related to comprehending performance for watertightness and crack control of concrete added with crack reducing agent concerning to high strength concrete mixs. It was confirmed that watertightness of concrete added with agent could be improved by evaluation absorption ratio, permeability ratio and pore size distribution of hardened concrete. As well resistance to crack resulted from shrinkage was transferred to better state by the addition of agent.

We proposed a conceptual design of the web-based agent model for global supply chain management(GSCM), where agents representing autonomous operational units, such as suppliers, factories, distribution center and customers, cooperate and are coordinated through the information exchange. The agent model assumed the hierarchical federated system. In the federated system, the agents of the same region are grouped and linked to the region-specific facilitator only through which communication between agents is allowed. The facilitator is responsible for monitoring and controlling the conversations consisting of the message flows across the agents. A web-based user presentation was also designed so that human users could involve in collaborative settings into the GSCM multi-agent system. In the conversation protocols which allow for complex coordinated behavior among agents, the KQML was extended to represent the messages. A GSCM scenario where the supply chain is formed upon customer order and supply decision is made was used to demonstrate the dynamics of the conversation protocols.

본 논문에서 제안하는 이동에이전트를 이용한 분산형 절전제어 방법은 다수의 센서와 이동에이전트를 이용하여 능동적 지능적으로 조명장치의 제어(on/off 및 디밍 조절 등)를 가능하게 하여 에너지 절감에 효과적이며, 다양한 능동규칙들의 적용에 의한 원격감시 및 제어기능 추가가 용이하므로 효율적 절전제어시스템 설계 및 구축에 따른 비용절감 등의 효과를 유도한다. 또한, 이동에이전트 기반의 센서네트워크 미들웨어의 기능을 통하여 상황정보나 사용자의 감성 등을 규칙화하여 실시간으로 이벤트 처리 및 제어함으로써 센싱 데이터의 효용성을 향상시킨다. 본 논문의 결과는 다양한 능동적 센서네트워크 응용들의 개발에 있어 제안한 이동에이전트를 이용한 제어시스템의 활용가능성을 제시한다.

In this thesis, the study on controlling of cracks of concrete box culvert in early ages is presented. The optimum construction method and economical analysis were proposed also through the experiment of the material and field test. As a result of the experiment of the material, using fly ash, CSA expansive agent and BELITE cement(type IV) showed good result in the control of cracks induced by heat of hydration and shrinkage. As a result of construction test analysis, the maintenance time of form system did not show a big difference in controlling of cracks. Control of distribution of reinforcement, spacing of expansion joint and use of BELITE cement showed big differences in the control of cracks in early ages. As a result of economical analysis, control of construction variables before construction can make it possible to reduce the repair expense.

다중개체를 제어하기 위해서 해결해야 되는 문제들 중 하나는 위치제어다. 위치와 속도를 제어하기 위한 모델로 augmented Cucker-Smale 모델이 존재했다. 하지만 기존 모델은 모든 개체에 동일한 시스템을 적용함에 따라서 개별개체의 특성을 살리지 못했다는 특징이 있다. 본 논문에서는 그 점을 보안하고 적절한 형태로 변형하기 위해서 초기 위치와 분포를 이용한 마할라노비스 거리를 계수와 통계학적 자유도를 적용해서, 모델의 수렴시간과 소모에너지를 동시에 줄이고자 한다. 모델의 성능 검증을 위해서 몬테카를로 시뮬레이션을 통해서 전체적인 경향성을 판단했고, 추가적으로 개별 개체의 움직임을 분석하여서 마할라노비스 거리 계수가 적절한 역할을 수행하고 있는지 확인했다.

본 연구는 콘택트렌즈를 중합 시 사용하는 교차결합제의 구조가 콘택트렌즈의 물리적 특성 및 약물 용출에 미치는 영향을 조사하였다. 4종의 교차결합제를 0.3%와 3%를 각각 사용하여 콘택트렌즈를 제작하였으며 약물은 안약에 사용하는 ofloxacin을 사용하였다. 친수성 교차결합제를 사용한 콘택트렌즈는 함수율과 습윤성이 향상되었으며 친수성 작용기가 많을수록 효과가 크게 나타났다. 약물용출 농도는 친수성이 강한 교차결합제 사용 시 가장 높게 나타났으며 교차결합제의 농도가 높은 콘택트렌즈는 용출되는 약물 농도가 낮고 용출시간은 길어졌다. 콘택트렌즈의 교차결합제 구조는 콘택트렌즈의 성능 향상과 약물 방출조절에 영향을 주었다.

For replacing Li metal ai Lithium ton Bakery(LIB) system. we used carbon powder material which prepared by pyrolysis of phenol resin as starting material. It became amorphous carbon by pyrolysis through it\`s self condensation by thermal treatment. Amorphous carbon can be doped with Li intercalation and deintercalation because it has wide interlayer. however it has a problem with structural destroy causing weak carbon-carbon bond. So. we used ZnCl$_2$ as the pore-forming agent. This inorganic salt used together with the resin serves not only as the pore-forming agent to form open pores, which grow Into a three-dimensional network structure in the cured material, foul also as the microstructure-controlling agent to form a loose structure dope with bulky dopants. We analyzed SEM in order to find to different of structure. and can calculate distance of interlayer. CV test showed oxidation and reduction
