The purpose of this study is to provide the guidelines for the planning and design of officetels, meeting the requirements of life in one-person household which is a new type in housing market. Literature survey is used as a research method. We analyzed the needs of officetel residents, by reviewing researches and by examining internet homepages and catalogs of 20 officetels sold since 2000. Case study analysis method is used as a qualitative analysis. The major findings of this study are as follows; 1) In dwelling unit space, it lacks the independence of working space and the privacy of living space. Therefore, the provision of various unit plans, such as 2-bay plan, unit with mezzanine floor or movable walls, layout of kitchen and dining area in window side, is proposed. 2) In communal space, it lacks the consideration of natural environments and the systematic maintenance. Therefore, the introduction of communal workshop and conference rooms and of various types of garden space, is proposed.

The purpose of this study was to identify kitchen and non-kitchen use of space for cooking and dining. Three rural villages, Kum-sung Ri, Young-san 1 Ri, and Yu-bang 2 and 5 Ri were selected for this study. Present and past use of space for cooking and dining was investigated by the field survey method. The major findings were that : 1) Both the kitchen and other space such as the outdoor courtyard(madang) were the space for cooking. 2) Dining activities took place in ondol rooms, the wooden floor room(maru), outdoor court yard(madang) and kitchen. In the winter eating activities took place in the kitchen where heating is provided. Many village people ate at a Western style or at a Korean style dining table(papsnag) in the kitchen. 3) Compared with study I, the present research found similar use of space for cooking and eating, with slight differences in space for eating.

In this study, a numerical method for soil-pile-structure interaction problems in multi-layered half-plane is developed. The total soil-pile-structure interaction system is divided into two parts namely, nonlinear structure part and linear soil-pile interaction parts. In the structure field, the general finite element method is introduced to solve the dynamic equation of motion for the structure. In the soil-pile structure interaction part, physical model consisting of lumped parameter, which is frequency dependent coefficient and determined by rigorous analysis method is introduced. Using proposed analysis procedure, the nonlinear behavior of structure considering soil-structure interaction can be efficiently determined in time domain and the analysis cost is dramatically reduced.

나노금속분말은 기존의 마이크론 입자와 다른 특이한 기계적, 전기적, 자기적 특성을 나타낸다. 나노금속분말 제조에서 가장 중요한 것은 오염되지 않은 고순도의 분말을 균일하고, 고분산된 입자를 제조하는 것으로 전기선폭발법(Electric Explosion of Wire, EEW)은 이러한 요구조건을 만족시킨다. 최근에는 전기선폭발법을 유체 내에 적용하여 분말을 제조하는 공정이 개발되었다. 이로 인해 고순도의 구형의 금속 나노입자를 얻을 수 있다. 본 연구에서는 물, 알코올, 에틸렌글라이콜 등 다양한 유체내에서 다양한 순금속 분말과 TiNi, SUS 등 나노합금분말을 제조하였다. 제조된 금속입자의 특성과 금속입자가 분산된 유체의 특성은 FE-SEM, HR-TEM, XRD, Turbiscan등으로 분석하였다.

This study performs the objective evaluation on simple comparison and calculation works by students under LED illumination conditions according to three types of color temperatures (7000K, 5000K, 3000K) in the classroom, Since the objective of this study is to develop an electric lighting conditions suitable for students in the classroom, the learning performance under three types of LED illumination conditions were analyzed. The 4 kinds of simple tests concerning with learning performance were developed and test results under natural light and LED illumination by 3 types of color temperatures were analyzed. There were differences by t-test in most cases among simple experiment results of different illumination conditions ($p{\leq}.05$). It was confirmed that illumination condition plays an important role when students simply compare words or perform arithmetic calculations. The experimental results of this study might be applied to designing better luminous environment.

대기-해양-천문 수치 모델은 주로 3차원 모델이고, 3차원적 해석을 위해서는 사용자가 쉽게 접근하고 사용할 수 있는 3차원 과학적 가시화 도구가 필요하다. 이러한 요구에 대응하기 위하여 무료/오픈소스 기반의 3차원 과학적 가시화 도구인 VAPOR가 사용자 친화적인 방향으로 개발되고 있다. VAPOR는 대기모델 WRF, CAM, GRIMs, 해양모델 MOM4, POP, ROMS의 직접 가시화가 가능하며, VAPOR 자료 형식 변환 과정을 통하여 천문 분야 모델(RAMSES) 가시화도 가능하다. 매년 개발을 통하여, VAPOR는 사용자가 많이 사용하는 일반적인 2, 3차원 표출 기능과 단순 통계 기능을 제공하게 되었으며, 향후 다중 모델 동시 표출 기능도 제공할 계획이다.

Antigenic potential of a novel cephalosporin, IDC7181 was examined a active systemic anaphylaxis (ASA) and passive cutaneous anaphylaxis (PCA) test, in guinea pig and mouse-rat models, respectively. In ASA test, IDC7181 induced the signs of restlessness in a few animals immunized with a high dose (100 mg/kg) of IDC7181 alone or in combination with Freund's complete adjuvant (FCA). In PCA test, only one of ten sera from the animals immunized with a high dose (100 mg/kg) of IDC7181 in the absence or presence of FCA showed positive reaction. The positive reaction, induced by IDC7181, which may be due to $\beta$-lactam ring, in ASA and PCA tests were negligible in comparison with those of traditional cephalosporins. Taken together, it is suggested that IDC7181 do not cause immunological problems in clinical dosage.

Micro-stereolithography technology is used for fabricating of 3-dimensional micro-structures. In some cases, this technology is more economical and simpler than MEMS and LIGA technologies based on semiconductor process. In this research, the micro-sterolithography apparatus that is more economical and simpler than current micro-stereolithography apparatus was developed. This apparatus uses UV lamp and optical fiber as a light source and tight delivery system, respectively.

본 연구는 대학생들이 인식한 어머니와 아버지의 애착과 부모됨의 동기와의 관계를 분석하고자 하였다. 연구결과는 첫째, 대학생들은 아버지에 대한 애착보다는 어머니에 대한 애착이 더 높은 것으로 나타났다. 둘째, 대학생들의 부모됨의 동기는 전체적으로 평균보다 높았지만 성별 차이는 없는 것으로 나타났다. 셋째, 대학생들의 어머니의 의사소통과 신뢰감 애착은 아버지의 의사소통과 신뢰감의 애착과 정적상관이 있었지만 아버지의 소외감과는 부적상관이 있었다. 어머니의 애착유형 하위요인 중 어머니의 소외감 애착이 높으면 아버지와의 의사소통과 신뢰감이 낮았다. 반면 어머니의 소외감 애착이 높으면 아버지의 소외감도 높은 정적상관을 보였다. 어머니와 아버지의 애착은 부모됨의 동기와 정적상관이 있었다. 특히 어머니와 아버지에 대한 애착요소 중 의사소통과 신뢰감 애착이 높을수록 부모됨의 동기가 높았다. 본 연구결과로 볼 때, 부모와의 애착은 자신이 부모가 되고자하는 동기에 영향을 미침으로 대학생을 대상으로 하는 예비 부모교육은 대학생이 미래의 부모가 되었을 때 자녀와 애착을 잘 형성할 수 있도록 하는 내용을 포함해야 할 것이다.
