애니메이션의 사전제작과정에서 캐릭터의 보다 효율적 제작, 분석, 평가을 위해 시각적 모델화및 데이터 베이스 구축이 필요했다. 캐릭터의 체격과 기질 관계를 조명하기 위해 W. 셀던의 체격기질유형 이론으로부터 정형화된 분석 틀을 구축하여 개념을 시각화하고 유형분석 모델을 만들었으며, 또한 케이스 스터디를 위해 세 애니메이션에 나타난 캐릭터의 유형들을 분석함으로써 모델의 적용 가능성과 나아가 애니메이션의 캐릭터에서 표현된 외적 형상과 내적 기질의 상관성을 추론하여 실제 적용이 가능한 기초적 데이터가 되도록 하였다.

This study intends to make a counterproposal for re-building existing high-rise/high-dense buildings and for planlessly re-constructing multi-dwellings. Also, it proposes the plan instruction fur reconstruction by small collective housings through annexing parcels in the residence Inner area. This study can be summarized as below: (1) Remained site generated by site boundaries can be utilized by annexing two or more parcels. (2) Vacant lots between buildings can be utilized as building space or common space by small-sized annexation. (3) Bad effect of residential environment caused by simultaneous development of total blocks can be minimized. (4) Formation of site size and plane, which are advantageous to reconstruction, is available. (5) Accessibility to neighboring roads can increase. (6) Residents' participation in development can increase in economical and planning aspect. In order to utilize these planning instruction, residents' participation and improved public ownership system for parcel annexation are required.

In this research, a heat pump system with a heat source network is suggested which utilizes solar heat and ground heat as heat source for cooling and heating. This paper describes the summary of the suggested system and the results of the annual energy simulation. The heating and cooling loads, the electric consumption and the COP were calculated by TRNSYS 16 and evaluated in the cases of different local conditions and different system compositions. In the results, the superiority of the suggested system has been quantitatively evaluated comparing with the conventional heat pump system using one heat source. Furthermore, it was more significant in cold climate, in which the heating COP was 146% increased compared the air source heat pump system, than it in subtropical climate, 119% increased.

In this paper, the optimal thermal storage time of an air-conditioning system with slab thermal storage in office building was analyzed on the basis of the gradient method algorithm. The sum of room temperature deviation and heat extraction rate was set to the criterion function. It was calculated that four hours is the optimal thermal storage time under the standard evaluation criterion. Furthermore, some case studies were executed by controlling ratio of weight functions of room temperature deviation and heat extraction rate in criterion function. It is possible to design many kinds of optimal operation of an air-conditioning system with slab thermal storage by controlling ratio of the weight functions in criterion function.

Ground heat pump systems utilize the annually stable underground temperature to supply heat for space heating and cooling. The underground temperature affects not only the underground ecosystem, but also the performance of these systems. However, in spite of the widespread use of these systems, there have been few researches on the effect of the systems on underground temperature. In this research, case studies with numerical simulation have been conducted, in order to estimate the effect of ground heat pump systems on underground temperature. The simulation was coupled with the ground water-ground heat transfer model and the ground surface heat transfer model. In the result, it was found that the underground change depends on the heat transfer from the ground surface, the heat exchange rate, and the heat conductivity of soil.

본 논문은 제2차 세계대전 이후 미국 캘리포니아에서 전개된 케이스 스터디 하우스(CSH) 프로그램을 대상으로 유럽에서 시작된 근대주택의 개념이 미국화되어 가는 과정을 파악하고 그 건축적 특징을 제시하고자 한다. CSH 프로그램은 미국식 근대주택의 개념이 설정되어 가는 과정에서 선도적인 기여를 한 것으로 이해되지만, 동시에 실행과정의 한계때문에 공공사업으로 확대되지 못하고 소규모의 실험적 프로젝트로 한정되었다. CSH프로그램의 실행단계에서 가장 큰 난제는 주택시장의 유통과정에서 효과적으로 대응하지 못하고 가격경쟁력을 잃어버린 점이다. 하지만, 유럽의 근대건축을 수용하고 발전시켜 미국식 실용주의에 근거한 독자적인 건축양식으로, 그리고 미국 근대건축의 원형(prototype)으로 이해될 수 있도록 했다는 측면에서 CSH 프로그램의 중요성은 높게 평가받아야 한다. CSH 주택들은 유럽 근대주의의 연장선상에서 실용주의를 기반으로 한 미국식 근대주택의 개념을 대변하는 위치에 있다.

Recently, ground source heat pump (GSHP) systems have been introduced in many modem buildings which use the annually stable characteristic of underground temperature as one of the renewable energy uses. However, all of GSHP systems cannot achieve high level of energy efficiency and energy-saving, because their performance significantly depends on thermal properties of soil, the condition of groundwater, building loads, etc. In this research, the effect of thermal properties of soil on the performance of GSHP systems has been estimated by a numerical simulation which is coupled with ground heat and water transfer model, ground heat exchanger model and surface heat balance model. The thermal conductivity of soil, the type of soil and the velocity of groundwater flow were used as the calculation parameter in the simulation. A numerical model with a ground heat exchanger was used in the calculation and, their effect on the system performance was estimated through the sensitivity analysis with the developed simulation tool. In the result of simulation, it founds that the faster groundwater flow and the higher heat conductivity the ground has, the more heat exchange rate the system in the site can achieve.

In connection with the plan for improving the residential environment gradually by analyzing the present condition of the reconstruction and parcel form of the housing area in a inner area, the main objective of this research is to develop a cooperative urban housing model based on the neighborhood agreement. The parcel form has a structure that is inappropriate for individual reconstruction； thus, the substantial improvement only through the residential environment improvement project has its limitations. As an alternative plan to resolve such limitations, I proposed a system that enables step-by-step reconstruction within the small-scaled blocks through the annexation of the land based on the neighborhood agreement. Nonetheless, I realized that it is difficult to apply such reconstruction system to individual housing. Therefore, I presented a design concept on the cooperative urban housing project as a residential form for the reconstruction inside blocks. A model plan vouches for its effectiveness. To apply substantially the cooperative urban housing plan based on the neighborhood agreement, we need to supplement the sectional plan system.

Recently, the use of renewable energy has been attracted due to the interest in energy-saving and the reduction of CO2 emission. In order to reduce the energy consumption of the cooling and the heating in the field of the architectural engineering, heat pump systems using renewable energy have been developed and used in various applications. In many researches, integrated heat pump systems are suggested which use solar and geothermal heat as the heat source for cooling and heating. However, it is still difficult to predict the performance of the systems, because the characteristic of heat exchange in each system is complicated and various. In this system, the performance prediction simulation of the heat pump was developed using a dynamic simulation model. This paper describes the summary of the suggested systems and the result of the simulation. The average temperature of the heat source, heating loads and COP were calculated with the cases of different local conditions, different system composition and different operation time by TRNSYS 17.
