This study examines and analyzes plan of Hanok which has been newly built at rural areas in Jeollanam-do province and is to present the direction in setting architectural plan of Hanok at rural areas. For the purpose of this study, analyzed the types of Hanok based on the topological characteristics of main house and main spaces including room, living room and kitchen. Five types of 105 Hanoks, type-I, type-II, type-III, type-IV and type-V were drawn on the based of the shape of main house and topological characteristics of main rooms including room, living room and kitchen. Type-I had spatial composition of main rooms in a row and showed similar shape of main house with traditional private houses in Honam region, type-II showed placement of living room in center and main rooms beside it, type-III showed change of type-II and placed kitchen and annex behind living room and similar plan composition with type-III and secured the area of living room and rooms by enlarging the number of rooms, and type-V had the shape of main house with twisted form and placed living room in the center and each room at side or twisted part to ensure openness of living room.

This study was conducted to apply the modular construction method to Han-ok. The modular method, which is differentiated from the existing one, means a construction method that equipments, windows and interior materials are prefabricated as a six-sided object at a plant and then they are assembled at the least process on the spot. As for the theoretical observation, the theoretical basis to apply the modular method to the modular housing and Hanok was divided into environmental and economic aspect. In order to apply the modular method to Hanok, the unit scale and size were selected and the plane of unit module Hanok was developed. And a standard with regard to the unit combination and material lifting transportation method was set and planned. In addition, through the comparison the unit modular Hanok to the existing Hanok, the difference was analyzed and the strength was identified in terms fo design method, structure, construction method, period and cost. In final, the conclusion, with regard to the economic, technical application in future, was drawn through arranging the study contents. The unit modular Hanok to carry out the high-quality dwelling through construction period reduction, standardized construction materials and improved insulation performance can meet the demands for a paradigm of new construction technology.

This Study developed library of parts, applied with 3-dimension character which has width, length and height and a reference plane, for the system development of BIM design on housing unit modular. The current BIM software has not the concept of a reference plane or work tolerance in modular, so the development of parts library applied to unit modular has not moved forward. So, we developed, in this study, parts library applied to windows, built-in-furniture, kitchen systems and knock down bathrooms, with a reference plane and work tolerance based on single roon prototype on urban-life-housings. BIM library can utilize changed size and work tolerance of parts, and fabricating reference plane will be created automatically when an engineer puts work tolerance in the BIM library with supplement of some category related to work reference. Through this BIM library development, we consider the part module can be used for housing complex planning, and architectural designers will be able to utilize the BIM library for housing complex design.

국내 모듈러 주택의 특성 및 MC 설계를 통한 건축자재 표준화 효과 분석

Modular construction is a process in which a building is produced off-site in module boxes using standard materials. Since the introduction of prefabrication in building construction, Modular Coordination (MC) has become an essential design tool in building design and construction. However, in Korea, the design standardization has not been adequately applied to modular construction. This study intends to analyze the current status of modular construction in Korea and explore the applicability of MC design in the construction industry. The analysis of the current status of MC design within Korean four major modular construction companies indicates that an incremental dimension is not properly used in horizontal planning modules, which results in a problem of increasing construction cost by high material loss rate. But, in vertical planning modules, a incremental dimension of 100 mm (1 M) is found to be used although the structural system varies among manufacturers, which demonstrates the potential for an open system to be well applied in modular construction, despite different structural systems.

Shockwave Simulations and Visualization for Teaching Quantum Chemistry

이창재,Lee, Chang-Jae Korean Chemical Society 2009 대한화학회지 Vol.53 No.2

양자화학에는 추상적이거나 비직관적인 개념이 많이 존재하여 학생들이 이해하기에 어려움 을 준다. 다행히, 전통적인 강의실에서의 강의를 보조할 멀티미디어 웹 응용프로그램을 제작할 강력한 도구들이 웹 기술의 발전으로 많이 생겼다. 이 논문에서는 이 문제를 다루는 한 방안으로서 쇽웨이브 기술을 이용하여 웹 브라우저 상에서 쌍방향 시뮬레이션과 시각화를 동시에 해결하는 방법을 제시한 다. 여러 예를 통하여 어떻게 쇽웨이브 기술의 특성을 이용하여 웹에 기반을 둔 학습 자료를 용이하게 개발하는가를 보여준다. Quantum chemistry has many concepts that are either abstract or counterintuitive, giving students difficulties in understanding them. Fortunately, the advancement of web technologies provides us with hordes of powerful tools to produce rich multimedia web applications that supplement traditional classroom teaching. In this paper we present an approach to address this issue that combines interactive simulations and visualization on the web browser using Shockwave technology. With several examples, we show how to take advantage of the features of the Shockwave technology in developing web-based course material with ease.

구리 계열의 Cu(NO2)2·3H2O와 CuCl을 중합촉매로 사용하고 다양한 용매, 리간드와 염기의 함량을 변화시켜 poly(2,6-dimethyl-1,4-phenylene ether)(PPE) 중합반응을 고찰하였다. 이 가운데 CuCl/1-methylimidazole/ ammonium hydroxide 시스템에서 가장 높은 중합 수율을 나타내었다. 한편, 몇 가지 다른 유기용매와 메탄올의 혼합용매 시스템에서 용매의 성분비율을 변화시켜 용매의 조성이 중합반응에 미치는 영향을 조사하였으며 2,4,6-trimethylphenol (TMP)를 사용하여 TMP 함량에 따른 분자량 조절 효과를 조사하였다. 클로로포름/메탄올 9/1(v/v) 혼합용매를 사용했을 때 가장 높은 중합 수율과 높은 분자량을 갖는 중합체(M(n): 55 K; M(w): 92 K; PDI: 1.7)를 얻었다. 구리 일가 촉매인 CuCl 과 CuI를 사용하여 서로다른 짝이온, 즉 Cl-와 I- 이온이 중합결과에 미치는 영향을 조사하였다. 촉매의 활성 비교를 위하여 산소 흡수량(oxygen-uptake)을 측정하였으며, 중합반응의 부산물인 5,5`-tetramethyl-4,4`-diphenoquinone (DPQ)의 함량을 자외선 분광기(ultraviolet spectroscopy)를 통하여 분석하였다. Poly(2,6-dimethyl-1,4-phenylene ether) (PPE) was synthesized using Cu(NO2)2·3H2O or CuCl catalyst with various amounts of ligand and base in several different solvent systems. CuCl/1-methylimidazole/ammonium hydroxide was found to be an effective catalyst system which showed the highest polymer yield and molecular weight. The effects of catalyst/monomer ratio, different amine ligands, and the content of mono-functional reagent 2,4,6-trimethylphenol (TMP) additive on the polymer yield and molecular weight were investigated. Among the co-solvent systems used in this polymerization, chloroform/methanol 9/1(v/v) gave the highest polymer yield and molecular weight (M(n) 55 K, M(w) 92 K, PDI 1.7). The catalytic activity between CuCl and CuI was compared by oxygen-uptake experiments and the formation of sideproduct, 5,5`-tetramethyl-4,4`-diphenoquinone (DPQ), was analyzed by ultraviolet spectroscopy.
