As household energy consumption has increased, serious environmental problems, such as resource depletion and global warming, are becoming global issues. It is essential to conduct the energy use of residents living in apartments in order to come up with alternative solutions for energy savings. Therefore, this study examined the energy use awareness of apartment residents and their energy use behavior by various types of awareness. To understand their energy use behavior according to the awareness of the subjects, the energy awareness dimension was created with five factors and they were subject to a cluster analysis; then, the subjects were categorized into three groups. Finally, the difference of energy use behavior was examined by groups of energy awareness. G1 represents the group that is indifferent to energy savings and believes that convenience is an important factor. Also, with respect to energy use behavior, this group tends to pursue convenience. G2 is the group that is conscious of energy use costs thereby enduring some inconvenience, and shows savings behavior in daily life and household affairs. Although, G3 is very aware of the significance for the necessity of energy saving, their energy saving behavior is relatively negative. Regarding these different characteristics of each resident group in their energy saving awareness and behaviors, diverse methods and promotion in energy education are required. Furthermore, an effective energy policy should be established based on the understanding of energy consumption.

The purpose of this research is to identify the everyday life culture, housing satisfaction and housing importance of older Korean-Chinese living in Harbin, China. Social survey research using the questionnaire was conducted from August to October in 2011. A total of 94 usable samples were analyzed by the SPSS version the 18.0 statistical program using frequency, percentage, cross-tabulation, factor analysis, and Pearson's correlation. The major findings were as follows. Firstly, older Chinese in Harbin were assimilated into Chinese culture such as national holidays and respectful people, but acculturated in terms of their daily food, and their preference to live in a Korean-Chinese village. Secondly, they had mainly lived in multi-story houses, the so called Chinese-style apartments. The average size of their living space was $80.33m^2$ and they were usually unsatisfied with their neighbors and floor treatment lacking Ondol(溫突). Thirdly, 5 factors affecting on housing value orientation were 'physical characteristics','emotional characteristics', 'economic characteristics', 'social characteristics', 'neighbor characteristics/reputation of the house' and they explained 73.9%. 2 factors affecting on housing satisfaction were 'inner complex/inner space' and 'neighborhood environment' and they explained 69.4%. In conclusion, some policy is needed for Korean Chinese living in Harbin for their well-being when it comes to their housing needs and conditions. Given the nature of big city, Harbin and its attraction, younger Korean-Chinese tend to be rapidly assimilated into Chinese culture. However older people in Harbin think that it is important for their children to learn both countries' languages and cultures in order to be successful, so some concrete policies and supports are needed.

This study examined 19 papers published from 1977 to 2000 based on the objective frame evaluation. This purpose of this study was to examine the trend of Hwabyung research and to serve as a guide for the future 'Hwabyung' study. The results of studies were as follow. In the design of research, clinical studies are definitely dominant. As for the fields of research, the concept of Hwabyung was studied more frequently than the others. As for the authorship. psychiatrists prevailed but nursing professionals are on the increase. Research subject in clinical and survey study, patient was definitely dominant and the place of study was almost always a hospital (75%), data collection was higher on interview (58.3%). Hwabyung was considered unique culture bounded syndrome related to Korean culture. Frequent etiologic factor of Hwabyung were a husband's extra-marital affair, conflicts between houses wives and mothers-in-laws, and financial loss and suffering. From the incidence of Hwabyung, a greater number of patients with Hwabyung were middle aged women in the low economic and educational classes, and these were connected with the culture and the family system. The symptoms of Hwabyung included psychological and physical symptom, neurological disorder and disease behavior. Defense mechanisms and coping strategies for Hwabyung were somatization, suppression, orality, withdrawal, isolation, regression, help-seeking, complaining, and wreaking anger. Treatment of Hwabyung were medication, effort by herself, communication with families, consultation with psychologist, acupuncture, negative therapy, moxa, and Qi-kong. Psychiatric therapy, behavior therapy, nursing intervention on multi-interdisciplinary approach and psychiatric nursing approach were recommended for the nursing care of a Hwabyung patient.

Purpose: The objective of this study is to divide personal traits of the elderly living in a rural area into extraversion, agreeableness, openness, conscientiousness, neuroticism, and loneliness and to identify the relationship between personal traits and receptivitiy to sharing living space in communal shared housing. Method: Subjects of this study are the elderly of ages greater than 55 living in Yeongwol-gun, Gangwon-do. Depending on how often elderly welfare facility was used, places where the elderly gathered were divided into a senior citizen center, senior welfare center, and other places where they often gathered. The researchers visited each of the places directly and conducted a survey with face-to-face interviews. Result: The collected data consisting of 124 respondents were analyzed through SPSS statistical program. It showed that 5 personal traits, except for agreeableness, had statistically significant difference. Extrovert and low lonely elderly people had high receptivity. The relationship between personal traits and acceptable shared space revealed differently depending on the function of space. Especially, shared resting space was related to low emotion-oriented trait, such as neuroticism and loneliness, while shared hobby and sanitary space were related to strong management-oriented trait of conscientiousness. These findings demonstrate the importance of understanding personal traits in predicting receptivitiy to sharing living space. Also, it is necessary to compare the degree of receptivity to sharing living space based on personal traits and to plan shared space in several levels, such as full sharing, partial sharing, and individual use, to develop and supply communal shared housing successfully.

The co-channel interference is a primary factor of loss in multimedia mobile communications. In this paper, we present a performance of the frequency reuse partitioning to refrain the co-channel interference and maximize system performance. First, we analyze the co-channel interference using the frequency reuse partitioning through the statistical modeling. From this results, we decide on the frequency reuse partitioning for the system throughput which is maximized. Finally, analysis and simulation results show that the frequency reuse partitioning based cellular system can mitigate the co-channel interference and maximize the system throughput. The experimental results show that system throughput is maximized from 0.7 to 0.8 according to traffic road. We can maximize the system throughput using the results with cellular system design parameter.

ISO 26262 is applied to vehicle and electrical/electronic component manufacturers for minimizing car accidents and life damage by the extended use of electronic control equipments and their malfunctions. In this standard, safety requirements are required to be applied from the early stage of development upto manufacture and disposal stages throughout the total lifecycle of the full vehicular system, and electromagnetic compatibility must be also managed as an important consideration factor. Therefore, it is nowadays very necessary to research and develop EFS(EMC for Functional Safety) to be applied in each stage of the design, manufacture, accreditation, use, maintenance stages of cars. In this paper, how EFS can be applied for the application of ISO 26262 is described. By the enforcement of this suggestions into the legal requirement or New Car Assessment Program(NCAP) test items, it is necessary that car manufacturer have to perform some procedures for ensuring car safety by themselves.

With the sex role changes in the post-modern society, men are becoming increasingly interested in appearance and their bodies. Male muscles in particular, which also is a visual manifestation of masculine strengths, has become the focal interest for those men who care about appearance management. The purpose of this study was to identify the extent to which Korean culture emphasizes muscles in defining masculine body, and to understand Korean men's perception of muscle building and their bodies. For this purpose, a content analysis and a survey were conducted. The content analysis aimed at identifying the ideal masculine image represented in the ads featured in male fashion magazines. For the purpose of comparison, U.S. magazines were also examined. The result showed that male models' images shown in Korean magazines were not significantly different from the male images in American magazines in terms of the body size, muscularity, and the nudity of the models. A survey to 339 men aged between 20 to 50 living in Seoul area was conducted to explore the motives of muscle building, the criteria men use to evaluate muscled bodies, and the influence of muscle building on body satisfaction. Factor analysis and analyses of variances followed by Scheffe multiple comparisons were conducted for data analysis. The results showed that physical appearance improvement is one of the motives of muscle building especially for younger men. Muscle building in general is found to contribute positively to men's body satisfaction.

The deformation modulus of rock masse is a very important design factor for the computation of stability of tunnels and their support systems. Several empirical formulas to estimate the deformation modulus using simple rock classification methods such as RQD or RMR are widely used because field tests to evaluate the deformation modulus are very expensive and time consuming work. However, these formulas can be depended on experiences from the characteristics of local sites in each country. Therefore, in this study, the applicability of empirical formulas was analyzed by comparing estimated value with the measured value from eight sites in South Korea. The results show that the estimated value based on the empirical formulas partially have tendency to overestimate. Especially, in case of sedimentary rocks, it was too difficult to apply to the empirical formulas because there was no relationship between estimated value and measured value. For these reasons, additional data from many tests and accurate analyses are necessary to evaluate the estimation method for the deformation modulus considering the local characteristics of rock masse.

In general. fiber-optic medical endoscopes are made from glass step index (SI) fibers. These endoscopes have limitations in both image quality and mechanical properties. In particular. the image resolution of the SI endoscopes is limited to about 5$\mu$m. In this study the image resolution of plastic graded index (GRIN) super-resolution image guides with pixel sizes from 7 to 2.5 $\mu$m were measured and compared with those of 91ass SI image guides. There is an improvement in resolution of the plastic GRIN image guides as the microfiber diameter is reduced from 7 $\mu$m to 2.5 $\mu$m. The measured resolution of plastic GRIN image guide with 2.5 $\mu$m microfibers is more than a factor of two higher than that of g1ass SI image guide with 5$\mu$m microfibers. This new design of optical systems could have a major impact on a wide array of future optical systems used in defense. industrial, and medical applications.

Recently, by the increasing of data transmission rates, PCB is required high-speed data transmission rates and thin packaging. So optical PCB which is the combination of electrical layer and optical layer can be one of the solution to overcome the limitations of conventional electrical PCB. The most important factor in the implementation of optical PCB is optical interconnection. So the research on high-efficiency and passive alignment has been active. In this paper, we suggest built-in lens pluggable waveguide and we simulate its coupling efficiency and structural stability. Optical simulation results show that the proposed structure has higher efficiency than no lens structure about 1.86 times in transmitter and about 1.42 times in receiver. In structure simulation, inner lens has no damage in desorption process. Therefore, we shown that the proposed structure has a high coupling efficiency and structural stability.
