Due to recent change in fire stations, this study aims to propose improved directions for planning of 119 rescue centers through its analysis of spatial organization and characteristics by functional area based in case studies of new-design centers. The Korean 119 rescue centers have changed in terms of function and roles in line with the flow of changing social environments, so it has been required to give new spatial change to these centers. It's meant in this study to classify compulsory special service spaces for the 119 rescue centers by domain and to suggest design guidelines for each type of spaces. Eight case of recue centers that were newly built in and after 2008 were selected and analyzed to serve the purpose. Finally, the results of this study were as followed: First, each of the rescue centers is divided into several domain depending on the type of work, and there are meaningful characteristics in the vertical and horizontal spatial layout of the individual spaces. Second, there are specific differences among the spaces in the spatial occupation percentage. The percentage of the space for community service is obviously lower in the 119 rescue centers in Seoul than in Incheon. Third, the domain classification criteria of this study are selected based on earlier studies, and another space for community service is newly added as a result of making a case study.

The architecture reflects geographical characteristics such as geographical environments and climate, it has the characteristics and cultural characteristics of the region that has been constructed. Hansen Village constructed in Period of Japanese Occupation at 'Sorok-Island' in Go-heung, Jeollanam-do was also based on this point. The village, which is a ward of Sorok-Island Province, consists of a village in which patients are self-sufficient in economic and social activities, unlike the modern hospital systems where patients and treatments are concentrated in a single room. Additionally, the facilities for patient acceptance were gradually expanded, with limited interaction with external. Sorok-island shows the expansion of the village center where the new village is formed with the increase of the number of the early adopters in the 1910s and the accommodation facility is built, and it gradually increases the necessary space by opening and repairing the existing facilities by the 1990s Change. In addition, the spatial composition of the village can be divided into three types : decentralized, centralized and single-shift ; it has the same causal relationship as the village's formation. The purpose of this study is identifying the uniqueness of Sorok-Island by analyzing the correlation between the formation of a village to accommodate Hansen Patients in Sorok-Island and the spatial Component Factor.

In these day, the environmental issues of climate change have been continuously highlighted and there is an active discussion on the transition from fossil fuel-based energy to eco-friendly energy use. This study considered psychological attitudes as a major influencing factors for successful implementation of a hydrogen society totally based on the use of hydrogen energy, which is regarded as an alternative energy for future. Accordingly, familiarity, risk perception, and acceptability of psychological factors were investigated. In addition, this study identified whether there are differences in psychological factors according to the general characteristics of gender, age, occupation, and housing type. The results showed that awareness of hydrogen cars and fuels is below the average level, and we also have obtained the implication that social knowledge sharing should precede the implementation of hydrogen policy. Although we found that the degree of urban acceptance of hydrogen energy was high, it was also confirmed that the charging infrastructure was generally perceived as having a high risk. Our findings implicate that it is necessary to figure out policy strategies for suitable locating charging infrastructure in order to promote the use of hydrogen energy more.

As expanding of service robots into the human life, the needs of robots are increased. The experts group forecasted that the robot market would grow rapidly in a short time, robot companies should compete with others for prior occupation in a market. In this research, we proposed a framework of robot identity design based on building methods of product identity and developed a case study. Identity is one of the strategies to distinguish from competitors through managing image united. It is possible to apply this identity approach on robot area, which was used for making image of companies, brands, and products. In general, identity has visual, invisual features, which can be classified into three elements; Robot Philosophy, Functional Affordance, Family Look. Robot philosophy means the vision or philosophy of a company through robot development, functional affordance is a character or role to serve and family look includes visual design elements like as shape, color, material, graphic, behavior etc. We suggest that this guide will be applied to build identity of following series of a model, models of same service group and all models of a company or commercial space.

The high rate of urban crime is a main issue that needs to be dealt with in this high-tech society. With the rapid increase of urban crime, research has mainly focused on topics either on a global or a local scale, such as cities or communities and houses or buildings, without reliable observational data. This study makes the best use of the nationwide surveys carried out by Korean government agencies for the analysis of urban crime patterns and factors in major Korean cities. The aims of this research are threefold: understanding the relationship between urban crime patterns and socio-economic differences in cities, determining the effect of residence types on the urban crime patterns; and uncovering potential influential factors of a crime victim's individual characteristics. The statistical methods used for the analysis of social statistical data are as follows: simple regression, logistic regression, one-way ANOVA and post-hoc test. This research found that the patterns of urban crime rate in cities have a certain tendency toward the cities' socio-economic and geographical differences. The residence type is an influential factor showing a close relation to the crime rate. Personal issues, such as the types of occupation, education, marriage, etc., are directly relevant to victims of crime.

In this paper, the resonance characteristics of zigzag wire dipole antennas are first analyzed by the method of moment(MOM) for shortening the space occupation length of straight wire dipole antenna Considering the shortening effect the integrated zigzag dipole antennas with the simplified microstrip feed are designed. Since the integration gives rise to discontinuities due to antenna line width with abrupt bend angles, the compensation by the chamfer is applied. Futhermore the integrated parasitic zigzag lines are properly attached to both sides of substrate for compensation of the effect of the dielectric substrate, hence improving the resonance characteristic. The design results at UHF and ISM band are verified with experiments.

This paper has focused on comprehending the interior designs and characteristics of modern department stores in Korea by looking into the birth and changes of those built under the Japanese Forced Occupation Period. The first modem department stores including Mitsukoshi, Georgia and Hwashin Department Stores began to appear in Korea under the Japanese Colonial Rule. They considered a variety of architectural elements like construction planning, shop arrangement, path of customer movement and interior design. The interior of modem department stores aimed to pursue the so-called modernization movement, but failed to fully contain the unique characteristics of the times in that particular period. Modem department stores took on new western styles prevailed in Korea and were characterized by the eclecticism in which various architectural forms exist together. In other words, their interiors implied a sign of the times in the confusing and corrupt world then. Especially those modern department stores were designed, repaired and extended by foreign designers who were ignorant of the history of Korean architecture. What is worse, their further remodelling practices made big mistakes by considering only functional and economical aspects and giving a back seat to the architectural and historical value of existing modern department stores. Therefore, we should make more efforts to study and conserve the fundamentals of modem architectures like modem department stores in order to have better understanding of the aesthetic value of indoor space and facilitating smooth communication between past and present.

Insulation coordination is a key problem in UHVDC systems in terms of safety and cost. Although high-voltage ±1100kV UHVDC projects are being planned in China, the characteristics and key points of high-voltage systems have not yet been analyzed. This study aims to improve the safe, effective operation of these high-voltage power transmission systems. First, we analyzed two typical insulation coordination schemes used in ±800kV UHVDC systems in China. Next, we used the two typical ±800kV insulation coordination schemes as a reference to analyze the ±1100kV UHVDC system. Finally, we compared these schemes and proposed an effective insulation coordination solution, as well as developing principles for ±1100kV UHVDC systems. Our findings indicate that the points enduring the highest voltage in the system should be protected separately by special arresters. Our analysis of the insulation coordination of ±800kV and ±1100kV UHVDC systems concluded that, in ±1100kV UHVDC systems, the main goal of insulation coordination is to lower the insulation level of points enduring the highest voltage. However, in a ±800kV UHVDC system, the main goal is to reduce the cost of manufacture for arresters, as well as the space occupation in the valve hall, with an acceptable insulation level.

Survey reports of election opinions consist of numerous cross-tabulations between socio-demographic variables and political opinions including preferred candidates. Since socio-demographic variables are related each other, duplicate interpretations arise. The aim of this study is twofold: The first is to separate the effects of socio variables such as education, occupation and income from the effects of demographic variables such as region, sex and age. The second is the visualization of multiple cross-tabulations in low-dimensional space by extended doubling technique of correspondence analysis. Survey researchers may get some help from this study to present their survey results more lucidly and visually.

The black hole occupation fraction in dwarf galaxies can provide an important clue for understanding the black hole seed formation. As a pilot feasibility study, we performed a KVN radio monitoring campaign over 8 months for 4 dwarf galaxies. Two galaxies (IC10 and NGC1569) are detected at 22 GHz, respectively with 39 mJy, 83 mJy. The measured flux (rms) variability is 13% and 8%, respectively for IC10 and NGC1569, while the mean flux uncertainty is 25% and 12%. Thus, the detection of the radio flux variability is at best marginal. Detecting flux variability of faint sources (i.e., 22 GHz flux < 200 mJy) seems challenging with the KVN single dishes. Combining with the 1.4 GHz flux measurements from the NVSS, we find that these two galaxies have a steep spectrum, supporting that the radio sources are AGNs. Instead of a monitoring, single-epoch multi-band observations can be effective for identifying radio AGNs by providing the constraint of the radio continuum slope.
