Recently, apartment housing tends to increase 3-4% every year by economic growth and development of construction technology in domestic construction industry. According to this tendency, construction enterprises are providing high-quality and various residential space, and residents also want high-quality apartment housing without any defect. Construction company make efforts to decrease construction defects in order to satisfy all the residents, and to improve company value. However, it is impossible to have no defect in construction because construction works are combination of many different complicated process. Because of the responsibility for the defect, conflicts between construction company and residents have been occurred. This study suggests defects management method that can be used from defect register phase to defect repair phase with a function of smart-device of the high penetration rate. The effectiveness use of the suggested method might save defects maintenance time and improve resident satisfaction about construction quality.

As of 2016, the total traffic usage of handicapped people were 24.8%. Buses (25.6%) have the highest rate of travel, with the exception of "walking (33.5%)" as the main means of transportation for these handicapped people. Therefore, the Seoul Metropolitan Government expanded the low-floor bus, which is a means of transportation for the underbelly, to 30% by 2015, but the satisfaction level of mobility improvement of the underbelly was only 2% To 55%. In fact, increasing the percentage of low-floor buses is merely a superficial solution, and there are many restrictions on solving fundamental problems with limited budgets. Therefore, in this study, we use statistical analysis R, with a simple data manipulation and visualization function, to grasp the living area and life pattern of handicapped people in Seoul city.

Cancer is still a threat to human beings. The incidence and mortality rate of cancer have been gradually increasing as the life span has been lengthened. Radiotherapy is one of the most commonly used treatments for cancer. This study explored the influence of social support and stress on sick role behavior of patients receiving radiotherapy for cancer. The subjects for this study were 60 patients undergoing radiotherapy for cancer, selected from the radiotherapy treatment unit of the out patient departments of two major medical centers in Jeonju. Data were collected from February 1 to 28, 1990 by a Likert Scale Questionnaire and an interview schedule designed by the inverstigator. Data analysis included percentages, mean and standard deviation, t or F-test, Pearson Correlation Coefficient and stepwise multiple regression. Results included the following : 1. Support came primarily from sons and daughters (90.1%) ; the type of support was primarily emotional support from friends(60.0%) ; informational support came from health personnel(81.7%) ; and material support was sons and daughters(40.0%) ; satisfaction with support was highest for the spouse(4.02$\pm$.52). 2. Among the patient's demographic status was occupation the was the only socioeconomic characteristic influencing sick role behavior (F＝2.91 , p＝.029). 3. Directly perveived support was positively correlated with sick role behavior (r＝.2374, p＝.034). 4. Stepwise multiple regression was used to determine the predictors of sick role behavior. Directly perceived support was the most significant predictor accounting for the hightest contribution to sick role behavior(5.6%). Directly perceived support. socioeconomic status, perceived stress and indirectly perceived support variables together, accounted for only 6.8% of sick role behavior.

Today, our lifestyle and residential culture has been changed have been changed by interchange with various countries in various sides. In order to become an internationally recognized residential environment designer in this environment, we must understand the housing viewpoint of residents in a country first. Therefore, this study was intended to obtain useful material for residential environment design of both countries by comparing the housing viewpoint between Chinese students studying in Korea and Korean students. A questionnaire was conducted on 205 Korean students and 193 Chinese students (Korean race) from Y University in random sampling basis. The result is as follows. First, both Korea and China have a higher ratio of apartments in both current and previous types of house. But, both Korea and China have similar ratios between detached house and apartment for a desired type of house at the time of moving in. Second, Korean and Chinese university students consider and as the most important functions of residence, and Chinese university students consider more functions of residence than Korean students. Third, both Korean and Chinese consider a living room as the most important space among housing spaces, but Chinese consider a private room more importantly than Korean. Fourth, overall satisfaction rate of Korean students for current houses was average, and most Chinese students were generally satisfied with their houses.

cdma2000 offers several enhancement as compared to TIA/EIA-95, although it remains fully compatible with TIA/EIA-95 systems and allows for a smooth migration from one to the other-Major new capability include:1)connectivity to GSM-MAP in addition to IP and IS-41 networks; 2) new layering with new LAC and MAC architectures for improved service multiplexing and QoS management and efficient use of radio resource ;3) new bands and band widths of operation in support of various operator need and constraints, as well as desire for a smooth and progressive migration to cdma 2000; and 4) flexible channel structure in support of multiple services with various QoS and variable transmission rates at up to 1 Mbps per channel and 2 Mbps per user. Given the phenomenal success of wireless services and desire for higher rate wireless services. improved spectrum efficiency was a major design goal in the elaboration of cdma2000. Major capacity enhancing features include; 1) turbo coding for data transmission: 2)fast forward link power control :3) forward link transmit diversity; 4) support of directive antenna transmission techniques; 5) coherent reverse link structure; and 6) enhanced access channel operation. As users increasingly rely on their cell phone at work and at home for voice and data exchange, the stand-by time and operation-time are essential parameters that can influence customer's satisfaction and service utilization. Another major goal of cdma2000 was therefore to enable manufacturers to further optimize power utilization in the terminal. Major battery life enhancing features include; 1) improved reverse link performance (i.e., reduced transmit power per information bit; 2) new common channel structure and operation ;3) quick paging channel operation; 4) reverse link gated transmission ; and 5) new MAC stated for efficient and ubiquitous idle time idle time operation. this article provides additional details on those enhancements. The intent is not to duplicate the detailed cdma2000 radio access network specification, but rather to provide some background on the new features of cdma2000 and on the qualitative improvements as compared to the TIA/EIA-95 based systems. The article is focused on the physical layer structure and associated procedures. It therefore does not cover the MAC, LAC, radio resource management [1], or any other signaling protocols in any detail. We assume some familiarity with the basic CDMA concepts used in TIA/EIA-95.

As the population ages, health problems of the elderly, including functional disorders and cognitive impairment, have become some of the most important social issues in Korea. The purpose of this study is to discover the rate of prevalence and factors related to dementia among the elderly in Jeju Province. 2405 elderly in Jeju Province were interviewed, using a questionnaire consisting of sociodemographic characteristics： health behavior, quality of life, and MMSE-K. Prevalence of dementia was 9.4%(11.7% of females, 4.1% of males). Factors related to dementia, analyzed by multiple logistic regression, were age, working status, subjective health status, social support, and subjective economic status. In community health care for the elderly, factors relating to dementia have to be considered. When planning community health care, priority should be given to the elderly who： need care but live alone； lack social support； have a low standard of living； believe they are not in a good state of health； or whose life satisfaction is low.

One of very essential techniques for enlarging lifetime of energy-constrained wireless personal area network (WPAN) devices is energy-efficient transmission technique. If the WPAN is operated based on a TDMA protocol, the satisfaction of QoS requirements at each allocated time slot is another important factor to be considered. We therefore propose an energy-efficient transmission scheme for WPANs operating with a contention-free medium access protocol such as TDMA, as well as satisfying QoS requirement. The proposed algorithm determines the optimum combination of transmit power, physical data rate and fragment size required to simultaneously minimize the energy consumption and satisfy the required QoS in each assigned time duration, considering all the possible energy-minimization related parameters. The proposed algorithm demonstrated the improved performance results in terms of throughput and energy consumption via computer simulation.

Purpose: This study is to investigate working conditions including job stress among visiting nurses in public health centers in Korea. Methods: An social network based mobile survey was conducted in May 2017 (N=936, response rate: 47.0%). Results: The visiting nurses in this study had their average total career as a nurse is 13.7 years. The 68.3% of them were employed in an indefinite term, 17.0% were hired in a fixed term, and 11.0% came from outsourcing. They responded as high job-stress level including inadequate compensation (71.22/100) and job demands (71.91/100). They experienced down-talk (63.4%), swearwords (32.9%), being made a dirty face (39.9%), sexual jokes (30.8%), or being likened or evaluated with their appearance sexually (14.3%). Among the causes of job related conflicts and discrimination, deprived salary level was the most frequent reason (83.4%). The conflicts and discrimination were incurred by government officers (52.4%). There were no significant differences in overall job stress, emotional labor, organizational commitment, violence, and discrimination experience based on their employment types. Conclusion: The differences in working conditions among the non-regular nurses were trivial, and their overall working conditions were poor. It is necessary to improve non-regular nurses' working conditions in order to make up the limitations of the Korean healthcare system which is centered on hospitals.

This study is convergence study to identify the relationships among attitude toward death(ATD), spiritual well-being(SW) and awareness about organ donation(AAOD). The survey was performed on 214 nursing students in one university. Data was collected using a structured questionnaires and analysed with PASW 20.0. Study findings revealed that AAOD has a significant correlation with ATD and SW. ATD(${\beta}=-.159$), SW(${\beta}=.132$), idea about brain death's organ donation(${\beta}=.314$), and major satisfaction(${\beta}=.134$) about AAOD were most significant predictive variables. These variables accounted for 20.5% of the variance in AAOD. The findings indicate the necessity of developing educational programs to enhance nursing students's ATD and SW for increasing positive AAOD and further rate of organ donation, and follow-up study.
