The purpose of this study is to investigate the basic historical characteristics and its modern trend of Torajan traditional housing architecture in Sulawesi Province, Indonesia. The Toraja culture belongs to the cosmological culture with Cosmos centric characteristics. A traditional house, being called 'tongkonan' in Toraja region, is more than just a structure, representing the symbol of family identity and tradition. The Torajan architecture is a combination of the myth and cosmos, also regional conditions. With a short description of the general conditions and spiritual values of the Toraja, this paper explains the space-composition, the stylistic characteristics, the ornamental elements, construction, and its modern trend, etc. In general, it is raised on stilts several metres high, with a dramatically boat-shaped roof. Village layout varies according to size. The houses are arranged in a row, side by side, with their front gables facing north. Each house stands opposite its own rice-barn. The houses with their oblong ground-plans, built on piles set on stones. The interior is divided into three or four rooms, having few window. The houses are embellished with carving and paintings, and the facades display engraved and painted geometric and figural designs. The most frequent motif is the buffalo head, ranging from the realistic to the highly stylized. The Torajan traditional housing have experienced radical changes during the Modern period. In spite of the popularity of new modern house-styles, the traditional architectural style is often now constructed as an icon of Toraja identity. This paper will be helpful for understanding regional diversity of the traditional housing in Southeast Asia.

The purpose of this study is to the examine sense of community of the residents living in an apartment complex and the relevant features of the community facilities provided in the complex, such as actual facility conditions, needs and satisfaction. Five apartment complexes constructed after 2000, each containing more than 500 units were selected for this case study. The actual conditions of the community facilities regulated by current laws were inspected. Those facilities were the administration office, gym, multi-purpose room, sauna and shower room, indoor and outdoor children's play-grounds, study room, etc. 37 residents were interviewed to access their needs and level of and satisfaction with the provided community facilities. Based on the results, we suggest that basic community facilities for exercise, child care and children's recresion need to be provided regardless of the apartment complex size. The respondents revealed a medium level of sense of community, which was psychologically limited to their apartment complex. Indoor and outdoor children's play-grounds had great potential to encourage social interaction between the residents. The findings point to a need for improvement of the current relevant regulations with the perspectives of flexibility and application in terms of space size and mandatory types.

Purpose : As the number of the transportation poor has increased, the application of Universal Design on urban railway station has recently been focused. However, the current criteria used in domestic areas did not show the characteristic of facilities within urban railway station. Therefore, this study aims to explore the detailed criteria in applying ideas from Universal Design to sanitary facilities, especially toilets within railway station. Method : This study explores the criteria by evaluating findings from previous studies. First, the current situation of sanitary facilities in railway station is assessed. Then, the detailed criteria applicable to railway station toilets are concluded, by reviewing types of transportation poor and principles of Universal Design. Result : Findings from this study are as follows. First, the current criteria applied to railway station toilets lack ideas of Universal Design, so the better criteria applicable to sanitary facilities in railway station are necessary. Second, standard criteria used in domestic areas with newly additional criteria suggest that sanitary facilities should be established according to those criteria. Taken together, the better sanitary facilities should be provided to railway users through the application of Universal Design to railway station toilets. Implication : For the future users in railway station toilets, the additional research on types of diverse space and other sanitary facilities within railway station should have been continued.

A new analytical derivation of the elastodynamic point load solutions for an isotropic multi-layered half-space is presented by means of the precise integration method (PIM) and the approach of dual vector. The time-harmonic external load is prescribed either on the external boundary or in the interior of the solid medium. Starting with the axisymmetric governing motion equations in a cylindrical coordinate system, a second order ordinary differential matrix equation can be gained by making use of the Hankel integral transform. Employing the technique of dual vector, the second order ordinary differential matrix equation can be simplified into a first-order one. The approach of PIM is implemented to obtain the solutions of the ordinary differential matrix equation in the Hankel integral transform domain. The PIM is a highly accurate algorithm to solve sets of first-order ordinary differential equations and any desired accuracy of the dynamic point load solutions can be achieved. The numerical simulation is based on algebraic matrix operation. As a result, the computational effort is reduced to a great extent and the computation is unconditionally stable. Selected numerical trials are given to validate the accuracy and applicability of the proposed approach. More examples are discussed to portray the dependence of the load-displacement response on the isotropic parameters of the multi-layered media, the depth of external load and the frequency of excitation.

주택의 경우에는 소방법에서 제외 대상으로 되어 있어 화재가 발생하더라도 초기 소화에 골든타임을 놓쳐 대부분 인명사고로 이어지고 있다. 이처럼 주택에서 화재와 사망자가 많이 발생하고 있어 소방법을 개정하여 정부에서는 2017년부터 단독 주택에도 소화기를 의무적으로 비치하도록 하였다. 소방청 2018년 주택용 기초 소방시설 설치 실태조사 자료에 의하면 전체 비치율이 34.8%에 불과하다. 소화기는 화재 시에는 꼭 필요한 기구이지만 가정집에서는 기피 대상으로 생각하고 있다. 투박하고 빨간 색상으로 되어 있어 집안 분위기와 어울리지 않기 때문이다. 이제 소화기도 평상시에는 장식품과 팬시용품처럼 집안에 비치해 두다가 화재가 발생하면 화재를 진압할 수 있도록 심플하면서도 디자인이 다양한 소화기가 있어야 한다. 집안 어디에 두어도 장식물처럼 어울릴 수 있는 제품이라면 소비자들의 구매력을 향상시킬 수 있는 동기부여가 될 수 있다. 이제는 다양한 디자인으로 심플한 소화기가 개발되도록 관련업체의 디자인 개발이 실질적으로 이루어져 상품화를 기대한다.

This paper describes experimental study on GM-type pulse tube refrigerator (PTR). In a PTR, the pulse tube is only filled with working gas and there exists secondary flow due to a large temperature difference between cold-end and warm-end. The stability of secondary flow is affected by orientation of cold-head and thus, the cooling performance is deteriorated by gas mixing due to secondary flow. In this study, a single stage GM-type pulse tube refrigerator is fabricated and tested. The cooing performance of the fabricated PTR is measured as varying cold-head orientation angle and the results are used as reference data. Then, we divided interior space of pulse tube into three segments, and fixed the various size of screen mesh at interface of each segment to suppress the performance degradation due to secondary flow. For various configuration of pulse tube, no-load test and heat load test are carried out with the fixed experimental condition of charging pressure, operating frequency and orifice valve turns. From experimental results, the fine screen mesh shows the effective suppression of performance degradation for the large orientation angle, but the use of screen mesh cause the loss of cooling capacity rather than the case of no insertion into pulse tube. It should be compromised whether the use of screen mesh in consideration of the installation limitation of a GM-type pulse tube refrigerator.

산업화 이전의 화재사망자의 사망원인은 대부분 화염접촉에 의한 열화상이었다. 그러나 1990년대 이후 획기적으로 경제가 발전함에 따라 주거주공간이 대형화, 복잡화되고 내장재가 고급화되고 있다. 그러므로 최근의 화재에서는 열화상에 의한 사망보다 유독가스 흡입에 따른 질식 사망자가 대부분을 차지하고 있다. 또한 보험범죄가 증가하면서 보험금 등 경제적 이익을 사취하기 위한 방화로 인한 사망자가 크게 증가하고 있다. 소방방재청 발표에 의하면 2006년 전국적으로 31,778건의 화재가 발생하여 총 2,180명의 사상자가 발생하였고 이중 446명의 귀중한 인명이 사망하였다. 특히, 화재사망자가 발생한 화재는 민 형사상의 분쟁요인으로 작용할 수 있으므로 정확한 화재원인 및 사망원인 조사의 중요성이 강조되고 있다. 그러므로 본 연구에서는 최근 전국화재 통계를 중심으로 화재원인별, 발생장소별, 연령별 사망자를 분석하고 화재사의 감식 방법 및 화재 시 인간행동 특성, 화상사, 질식사 및 화재사 등의 원인을 중점으로 고찰하고 한다.

This study attempted to identify the characteristics of chair design from furniture company, $K{\ddot{a}}llemo$, the furniture manufacturer in Sweden manufacturing mostly the limited edition of art furniture on the basis of the unique management philosophy. There are 12 artists manufactured chairs for $K{\ddot{a}}llemo$. Of them, this study selected 4 artists-Sigurdur Gustafsson, John Kandell, Komplot Design, Mats Theselius-who designed at least more than three chairs. Total 25 chairs were analyzed; 6 from Sigurdur Gustafsson, 8 from John Kandell, 3 from Komplot Design and 8 from Mats Theselius. The chair structure was divided into three parts, seat, back and structure and analyzed by material, color, type of legs and finishing. The following results were derived from the study. First, $K{\ddot{a}}llemo$ secured the regular customers who want to possess the chairs as the artistic works by continuing the small quantity mass-production system insisting that the maximum quantity of production is 360 pieces and the minimum quantity is 33 pieces. Second, the sufficient time and cost were invested in the initial phase of design. This approach seems to be deviated from the traditional business system that has to create the revenue at a glance, but ultimately induces the commercial success by exponentially increasing the revenue through the creation of various product lines. Third, $K{\ddot{a}}llemo$ provides the space that the artists who work for $K{\ddot{a}}llemo$ can sufficiently enjoy the mental composure and luxury required for the designers by strictly selecting the artists and providing the best environment for enabling the creative activities that look like the pure art area. This study enables the further analysis and research on other collections of $K{\ddot{a}}llemo$ that mass-produces the chairs on the basis of the unique philosophy in the world as well as in Sweden using more various kinds of analysis frameworks.

Purpose: Korea is expected to enter an aged society in 2018 and then a super-aged society in early 2025. The country's aging is progressing faster than any other country in the world. However, the foundation of the elderly friendly industry is weak, and measures at the government level are urgently needed. Especially, housing problems of the elderly are one of the most urgent measures to be taken. Korea does not have the minimum residential area standard for the elderly, and the current general minimum residential area standard is based on the survey of the housing situation without scientific evidence. Therefore, both standards need to be revised as soon as possible based on scientific evidence. Methods: The minimum residential area standard has been calculated following Karl H. E. Kroemer's Min or Max design also being called as-single cut and dual cut theory- as the maximum population value and minimum population value theory of Ernest J. McCormick. Therefore there is a need for a formula made using a few key factors, such as corresponding dimension, practical dimension, clearance, spare dimension, integrated dimension. These elements can be defined and used as formulas to calculate minimum residential area standards. Results: Assuming the results of the spatial variability in this study showed that it is possible to raise the standard of living in a terms of sustainable minimum size for the young, old and all residents. Implications: The government should set a minimum residential area standard with scientific grounds and set up a policy improving the life of people who live in an needy residential environment.
