With the increase in the number of multinational and multicultural research projects, the need to adapt health status measures for use in other than source language has also grown rapidly. Most questionnaire were developed in English-speaking countries, but even within these countries, researchers must consider immigrant populations in studies of health, especially when their exclusion could lead to a systematic bias in studies of health care utilization or quality of life. The purpose of this study was to translate and and culturally adapt the three most used neck and spinal pain disability questionnaires - the Neck Disability Index(NDI), Neck pain and Disability Scale(NPDS), and Functional Rating Index(FRI) - into the korean language and evaluated their reliability, in addition to item response pattern, to achieve a good cross cultural adaptation. Each translated questionnaire was found to have high reliability (FRI ICC (2,1)=0.86 ($95\%$ CI: 0.75-0.92); NPDS ICC (2,1)=0.90 ($95\%$ CI: 0.83-0.95 ; NDI ICC (2,1) =0.90 ($95\%$ CI: 0.81-0.94)). The reliability of the translated versions of FRI, NPDS and NDI were excellent.

The active noise control(ANC) method for noise problems solution generally uses filtered-X LMS algorithms. However, Filtered-X LMS algorithms were mainly used but these had a limitation that had to measure a transfer function of secondary noise path. However, newly proposed correlation-LMS algorithms have slightly much calculation and are minutely behind performance, these have a advantage not in measuring transfer function onerously so that we can easily adapt these in real time. Thus Co-LMS algorithm was developed to improve the real-time implementation performance under the variable input noise such as road noise environment. In this paper, the performance of the Co-LMS is presented in comparison with that of the Filtered-X LMS algorithm. Simulation results show that active noise control using Co-LMS have slightly much calculation and are minutely behind performance, these have a advantage not in measuring transfer function onerously so that we can easily adapt these in real time.

As we go about our daily lives, people often collect surrounding information and adapt to the situation. Computer development trends show that one wants computers to work like human beings, i.e. computers can sense its context and adapt corresponding to context changes. To implement this expectation, a context aware service layer is needed. In this layer, sensors capture its environment and send this information to the service center. Considering received information as its context, the service center seeks the suitable operation according to the context. Tills paper presents a context aware service which is applied in controlling air-conditioner. The air-conditioner includes sensors which are installed at some special positions in a room. Each of these sensors gathers comfort-influenced information like temperature, humidity and sends them to air-conditioner. The air-conditioner adapts its operation to the environment according to the sensed information. To control the air-conditioner effectively, we use a genetic algorithm which is suitable in adaptation issues. The simulation shows that the room condition can be maintained at a comfortable level by using context-aware services in the operation of the air-conditioning system.

The purpose of this study was to identify the attitudes of non-commercial foodservice dietitians toward hiring older workers who are over fifty-five years of age. Questionnaires were sent to 600 members of Korea Dietitians Association who are working in Seoul, Korea, Data from 233 usable responses were analyzed using the SAS package program. The study showed that dietitians do not have a favorable perception of hiring older workers. Dictitians responded older workers have more serious accidents than younger workers(under age 30). In addition, they think than older workers are harder to train, find it more difficult to adapt to adapt to new ways of working, and are slower in their work. On the positive side, the response did show that dietitians realize that older workers are not absent from work as frequently than younger workers and that they are more cooperate than younger workers. The data also showed that those dietitians who had more positive experience with older workers also perceive the workers in more positive way than those dietitians that have had a negative experience with older workers(p<0.001). Finally, dietitians who are working in industrial foodservice showed more positive attitudes toward older workers than the dietitians who are working in hospital and school foodservice(p<0.01).

Nowadays, Dynamic Adaptive Streaming over HTTP (DASH) has become very popular in streaming multimedia contents. In DASH, a client estimates current network bandwidth and then determines an appropriate video quality with bitrate matching the estimated bandwidth. Thus, estimating accurately the available bandwidth is a significant premise in the quality of video streaming, especially when network traffic fluctuates substantially. To cope with this challenge, researchers have presented various filters to estimate network bandwidth adaptively. However, experiment results show that current schemes either adapt slowly to network changes or adapt fast but are very sensitive to delay jitter and produce sharply changed estimation. This paper presents a novel bandwidth estimation scheme based on Moving Average Convergence Divergence (MACD). We applied an MACD indicator and its two thresholds to classifying network states into stable state and agile state, based on the network state different filters are applied to estimate network bandwidth. In the paper, we studied the performance of various MACD indicators and the threshold values on bandwidth estimation. Then we used a DASH proxy-based environment to compare the performance of the presented scheme with current well-known schemes. The simulation results illustrate that the MACD-based bandwidth estimation scheme performs superior to existing schemes both in the speed of adaptively to network changes and in stability in bandwidth estimation.

The purpose of this study is propose an alternative for flight attendants to acquire equipment that could enhance the ability to adapt in flying conditions. Introducing and acquiring weapon system, such equipments should be deeply considered in multilateral aspects; reinforcements in the overall strategic status in the army, the ramifications that can contribute to military resources, and economic situations in the country. To do this, we first induced several criteria that can be used for evaluating alternatives. After that, we applied the analytic hierarchy process(AHP) approach to putting all factors into considerations in decision making for equipment acquirement. The results of this study are expected to have usefulness in formulating strategies and policies in selecting equipment acquisition alternatives for flight attendants.

The effect of an adolescent's being in a multicultural family, including the psychological, cultural, and situational characteristics of this experience, in terms of how it impacts acceptance of Korean culture, social competence, and educational adaptation was investigated. 120 multicultural family adolescents who were enrolled in Seouland Gyeonggi-do middle and high schools were surveyed. The results were analyzed by the PASW Statistics v18 program. Firstly, it was found that the psychological, cultural, and situational characteristics of multicultural family adolescents were significantly affected by family's general economic level and their mother's occupation and nationality. Secondly, multicultural family adolescents with higher self-perception, good accommodation of crosscultural attitudes in Korean culture and more relationships with Koreans tended to adapt to Korean culture more easily. Thirdly, multicultural family adolescents who adapted to Korean culture more easily could also adapt to school life well, and those who had better interpersonal relations and more advanced problem-solving skills had better relationships with school friends.

This study is designed to develop a hospital communication program and to verify its effectiveness in graduate nurses self-esteem, communication conflicts, turnover intention and early resignation rate. The study method is a randomized control group with a pre-post test design. In order to help new graduate nurses adapt to the hospital, eight week hospital communication program is developed. The study participants are 104 nurses(47 experiment, 57 control) who have been working for less than six months. The data on self-esteem, communication conflict, and turnover intention was collected one week before the program and four weeks after the program. Then, the early resignation rate of the participating nurses was surveyed one year after the start of employment. The nurses who participated in the hospital communication program exhibit higher self-esteem, fewer communication conflicts, and lower early resignation rates than those who did not. However, effect in the turnover intention is not observed. Overall, the hospital communication program will help new graduate nurses adapt to hospitals.
