Indonesia is archipelago country and plural society which consist of diverse ethnic groups. This study select Java island and Java houses as a representative housing of Indonesia. The aim of this study is to present a comprehensive overview of traditional houses of Java in Indonesia by examining pre-existing literature. First, the Java House as a microcosm of the universe that shows universal and religious aspects. Furthermore, each building contains spiritual symbolism. These ideological aspects select the location and layout of the towns, villages and buildings, which create an order to the interior space. The space structure of Java housing is characterized by strong juxtaposition between east/west, front/back, public/private, male/female, and open space/ closed space. There is also a hierarchy of space, which were applied in floor level, height of space and lightness. The structure of the roof shows the best formativeness. Depending on the shape of the roof, the function of the building is shown, and also it represents the social rank and religious respect. Joglo's unique formativeness is an icon of the Java architect.

High-rise buildings are a common feature of urban cities around the world. These flexible structures frequently exhibit large vibration due to strong winds and earthquakes. Structural control has been employed as an effective means to mitigate excessive responses; however, structural control mechanisms that can be used in tall buildings are limited primarily to mass and liquid dampers. An attractive alternative can be found in outrigger damping systems, where the bending deformation of the building is transformed into shear deformation across dampers placed between the outrigger and the perimeter columns. The outrigger system provides additional damping that can reduce structural responses, such as the floor displacements and accelerations. This paper investigates the potential of using smart dampers, specifically magnetorheological (MR) fluid dampers, in the outrigger system. First, a high-rise building is modeled to portray the St. Francis Shangri-La Place in Philippines. The optimal performance of the outrigger damping system for mitigation of seismic responses in terms of damper size and location also is subsequently evaluated. The efficacy of the semi-active damped outrigger system is finally verified through numerical simulation.

The fundamental purpose of this study is whether Show Window Display actually affect on purchase and if it does, how much Show Window Display have influence on the buyer's satisfaction. Show windows are most important at clothing stores. The show open types of domestic clothing stores are usually open-type and semi open-type. Show Window Display types of low and middle prices stores are generally opened, horizontal and storied type and the shape, height, opening type and use of ground floor are different by regional distinct features. Generally Show Window Display are consisted by lights, mannequins and directed props. In buying patterns, an impulse buying has more stronger effect than a scheduled buying, a substituted buying and non-buying. An impulse buying are strongly affected by Design and others are prices. The reason why Show Window Display affecting on purchase is the satisfaction of Design and the strong stimulus to purchase(impulse buying), and then Show window Display used by all components strongly has an effect on it. Factors of purchase desires were Design, price and quality in order and factors of purchase motivations were the motivation of clothing design and the motivation of impulse buying. Thus the effects of Show Window Display and factors of purchase motivations are same. As a result of this study, differentiated Show Window Display methods of clothing stores affect the value of goods, the stimulus of purchase and fostering sales effectiveness. Therefore the instruction of Show Window Display methods are indicated by this study.

The probabilistic seismic safety assessment is one of the methodology to evaluate the seismic safety of the nuclear power plants. The site characteristics of the nuclear power plant should be reflected when evaluating the seismic safety of the nuclear power plant. The Korea seismic characteristics are strong in high frequency region and may be different from NRC Regulatory Guide 1.60, which is the design spectrum of nuclear power plants. In this study, seismic response of a nuclear power plant structure by Pohang earthquake (2017.11.15. (KST)) is investigated. The Pohang earthquake measured at the Cheongsong seismic observation station (CHS) is scaled to the peak ground acceleration (PGA) of 0.2 g and the seismic acceleration time history curve corresponding to the design spectrum is created. A nuclear power plant of the containment building and the auxiliary buildings are modeled using OPENSEES to analyze the seismic response of the Pohang earthquake. The seismic behavior of the nuclear power plant due to the Pohang earthquake is investigated. And the seismic performances of the equipment of a nuclear power plant are evaluated by the HCLPF. As a result, the seismic safety evaluation of nuclear power plants should be evaluated based on site-specific characteristics of nuclear power plants.

In this paper, we propose a practical method for setting up a daily production plan which can operate semiconductor fabrication factories more stably and linearly by determining work in process (WIP) targets and movement targets. We first adjust cycle times of the operations to satisfy the monthly production plan. Second, work in process (WIP) targets are determined to control the production progress of operations: earliness and tardiness. Third, movement targets are determined to reduce cumulated differences between WIP targets and actual WIPs. Finally, the determined movement targets are modified through a simulation model which considers capacities of the equipments and allocations of the WIPs in the fab. The proposed daily production planning method can be easily adapted to the memory semiconductor fabs because the method is very simple and has straightforward logics. Although the proposed method is simple and straightforward, the power of the method is very strong. Results from the shop floor in past few periods showed that the proposed methodology gives a good performance with respect to the productivity, workload balance, and machine utilization. We can expect that the proposed daily production planning method will be used as a useful tool for operating semiconductor fabrication factories more efficiently and effectively.

The equipment noise of machine room that generates at the building where human-being is living, is becoming to an object of strong civil appeal, and because it influences to the residential space through the floor or wall, its damage is very serious level. Accordingly, while an efficient forming of the sound insulating measures is earnest, as most of the transmission loss data was the material measured in laboratory, in case when it was applied to the job site, due to the precision difference of constructing work and the influence of detoured transmitting sound, the case of disaccord is the most. Therefore, this thesis has intended to present a fundamental data for an efficient establishment of sound insulation measure, by means of comparison analysis with the existing transmission loss data, after measurement of the transmission loss on the object of various walls, at the construction equipment machinery room.

It is predicted that Japan will be in super-aged society at 2010. Recently elderly house buildings with self-supporting life and personal care senior house types have supplied over the area. So Elderly house buildings in Japan were studied for characters of room arrangement, through documents and internet from Jan. 2007 to Apr. 2007. Five cases built since 2000 were examined. There were self-supporting life house type, personal care senior house type, convenient facilities, etc. There were not lots of facilities in the building. Generally multi-purpose dining room and general bath room, lots for car and bicycle or restaurant or kindergarten or home helper station or green food shop or day service or moving service or clinic were there. These facilities were shared with local community. The reason of not being many facilities in the building was that the houses were located at urban with good transportation and convenient facilities. The residents in the building were get the utmost of regional facilities and the local people did the facilities in it because scare facilities in the building and fluent facilities in region. So strong community was composed of the residents and local people, on the contrary.

The use of energy concepts in seismic analysis and design of structures requires the understanding of the input energy response of multi-degree-of-freedom (MDOF) systems subjected to strong ground motions. For design purposes and non-time consuming analysis, however, it would be beneficial to associate the input energy response of MDOF systems with those of single-degree-of-freedom (SDOF) systems. In this paper, the theoretical formulation of energy input to MDOF systems is developed on the basis that only a particular portion of the total mass distributed among floor levels is effective in the nth-mode response. The input energy response histories of several reinforced concrete frames subjected to a set of eleven horizontal acceleration histories selected from actual recorded events and scaled in time domain are obtained. The contribution of the fundamental mode to the total input energy response of MDOF frames is demonstrated both graphically and numerically. The input energy of the fundamental mode is found to be a good indicator of the total energy input to two-dimensional regular MDOF structures. The numerical results computed by the proposed formulation are verified with relative input energy time histories directly computed from linear time history analysis. Finally, the elastic input energies are compared with those computed from time history analysis of nonlinear MDOF systems.

The purpose of this research is to analyze the relationships between spatial characteristics and social functions of elderly center in apartment complex. The data for the analysis were collected from July 3 to 13, 2012 in Ulsan by interviewing 177 elderly persons from 56 elderly centers in apartment complex, and were analyzed with descriptive statistics, analysis of variance, and multiple regression analysis. The eleven questions for social functions of elderly center were developed by the researchers based on the related literatures and were categorized into four factors including kinship, social interaction, leisure activity, and community belonging. The social functions of elderly center were found to be evaluated moderately appropriate except for the community belonging. The results of the multiple regression analysis of total social functions of elderly center provide strong support for the model. Five variables (one-person household, health condition, location of the center, floor plan of the center, and user organization) are shown to be significantly related to total social functions of the elderly center.

Carbonated mineral waters fo $Ca(Mg)-HCO_3$ type spring out fissure of Jurassic granite in the valley floor of the Chungsong area. The water has been long as a Dalki medicinal water because of its unique therapeutic effect against clacium deficit, stomach and skin troubles, ect. The water has a high $CO_2$ concentration ($P_{CO_2}$=0.51~1.12atm) and exhibits strong pH buffering (5.9~6.26) by $H_2CO_3/HCO_3$ couple. Electrical conductivity ranges from 1,900 to 3100 $\mu$S/cm. Environmental isotopic data $(^{2}H/^{1}H, ^{18}O/^{16}O \;and \;^3H)$ indicates that the water is of meteoric origin recharged in the Cretaceous sedimetary strata distributed in upper part of the catchment area at least before 1950s, The high $P_{co_2}$ and carbon isotope data (${\delta}^{13}C=-3\sim-0.2\textperthousand$) suggest that the potential source of carbonated mineral water was originated in deep-seated $CO_2$ as wel as aboundant carbonate minerals of sedimentary desimetary rocks. The major source minerals of the dissoved species in the carbonated mineral water appear to be carbonate minerals, albite and K-feld-spar in sedimentrary rocks.
