The MTF(Modulation Transfer Function) is one of quality assesment factors to evaluate the performance of satellite images. Image restoration is needed for MTF compensation, but it is an ill-posed problem and doesn't have a certain solution. Lots of filters were suggested to solve this problem, such as Inverse Filter(IF), Pseudo Inverse Filter(PIF) and Wiener Filter(WF). The most commonly used filter is a WF, but it has a limitation on distinguishing signal and noise. The L-curve-based Modified Wiener Filter(MWF) is a solution technique using a Tikhonov regularization method. The L-curve is used for estimating an optimal regularization parameter. The image restoration was performed with Dubaisat-1 images for PIF, WF, and MWF. It is found that the image restored with MWF results in more improved MTF by 20.93% and 10.85% than PIF and WF, respectively.

In this paper, we design the radio interface protocols of wideband Wireless Local Loop(WLL) that uses wideband Code Division Multiple Access(CDMA), and propose the random access procedures on access channel and analyze the performance of the channel. The structure of radio interface protocols are designed by three modular parts to meet the requirements of IMT-2000 : radio resource controlling part that depends on the radio resources, connection controlling part that is independent of the radio resources, and application part that supports the interface between different parts and user terminals. In addition, we propose the random access procedures on access channel and analyze the performance of the channel. We assume that both near-far effect and shadow fading can be compensated by open loop power control. We observe that the number of access probes(delay) depend on the initial mobile transmission power and power increment, and the poor estimation of initial mobile transmission power might increase the average number of access probes.

1. The human body is the unification related to the powerful fascial network, I think. 2. Myofascial not only prevent and support the human body structure curdling but also keep the physical balance by dispersing traumatization properly. 3. Myofascial restriction will be developed into muscle deficiency and cause pains without releasing the muscle tension and the spasm. 4. Myofascial restriction affect and change the physical posture by losing the muscle elasticity and flexibility and by losing muscle supporting ability from gravitation. 5. The partial myofascial restriction affect the muscle and the adjoining joint supporting gravitation and cause the unbalance of the entire body.

This research was conducted to analyze structural relationships comparatively between job stress, job burnout and turnover intention that school dietitians, school nutrition teachers and school foodservice employees have. The target group is school dietitians and nutrition teachers who work in 180 elementary, middle and high schools and foodservice employees in 50 schools. The survey is limited to the schools which operate school meals directly or indirectly in Seoul and Gyeonggi province. As a result, job demand and lack of rewards were found the most significant factors in the dimensions of job stress. The quantitative expansion of school meals is important; however, it is necessary to reduce stress in the work environment for dietitians, nutrition teachers and employees in school foodservices to perform their duties with dignity and satisfaction.

본 연구는 치과진료실의 실내 공기질에 영향을 미치는 요인과 종사자의 실내자각증상과 관련성을 조사하여 치과위생사 개인의 발전과 건강 증진에 필요한 기초자료를 마련하고자 본 연구를 시행하였다. 전국(서울, 경기, 대구, 포항)의 종합병원, 치과병원, 치과의원의 치과위생사 210명을 대상으로 2011년 10월 1일부터 20일까지 자기기입식 설문지 조사를 시행한 후 회수하여 응답이 불분명한 5명을 제외한 205명에 대해서 분석 하였다. 수집된 자료는 SPSS WIN 15.0 프로그램을 이용하여 분석하였다. 그 결과 근무 중 휴식시간 유무별로는 근무 중 휴식시간이 없는 치과위생사가 67.3%로 높은 분포를 보였고, 건물 밖 외출 여부별로는 때때로가 54.6%로 절반 이상을 차지하였으며, 건물 밖 외출횟수별로는 1회 86.1%로 대부분을 차지하였으며, 근무기관의 계절별 자연환기 정도별로는 봄, 여름, 가을, 겨울 모두 1일 2회 이내가 절반 이상을 차지하였으며, 다음으로 1일 4회 이내 19.0%, 기타 9.8%, 1일 10회 이내와 하루 종일 2.4% 순이었다. 실내자각증상 호소율에 대해 살펴본 결과는 4점 만점 중 전체 평균이 2.45로 나타났다. 먼저 영역별로는 평균이 '목증상'과 '눈증상'이 각각 2.54로 가장 높았으며, 문항 중에는 평균이 '눈이 잘 피로해진다'가 3.00으로 가장 높게 나타났다. 근무환경 특성에 따른 실내자각증상은 야간진료 여부별로는 야간진료를 하는 치과위생사가 그렇지 않은 치과위생사보다 실내자각증상이 낮았으며, 야간진료 여부에 따라 유의한 차이를 보였다(t=2.07, p<.05). 실내자각증상과 직무스트레스의 관계는 물리환경(r=.259, p<.001)과 직무요구(r=.311, p<.001), 관계갈등(r=.172, p<.05), 조직체계(r=.158, p<.05), 보상 부적절(r=.197, p<.01), 그리고 직무스트레스(r=.275, p<.001)와 통계적으로 유의한 상관관계를 보였다.

As many companies have been interested in big data, they have invested a lot of resources to get more customer data. Some companies try to trade the data illegally. In order to collect more customer data, companies provide various incentive programs to customers. However, their results are normally much less than their expectations. This study focuses on exploring the relative importance of the factors which influence customer attitudes to providing his/her personal information. This study conducts a conjoint analysis to assess trade-offs among the five influential factors-monetary reward, concern for data collection, concern for secondary use, concern for unauthorized use, and concern for errors. This study finds that the customer attitude to providing personal information is most influenced by the concern for secondary use. Furthermore, it shows that there are some differences between the light internet user group and the heavy internet user group in the relative importances of these factors. The monetary rewards appeal to the heavy internet users, rather than the light internet users.
