본 논문에서는 궤환선형화를 이용한 일치기법을 사용하여 다수 무인기의 편대비행 제어기를 설계하였다. 제안한 기법은 한 대의 리더기를 중심으로 하는 집중형 방식이 아닌 분산형 방식으로, 각 개체의 제어입력은 인접한 개체만의 정보만을 이용하여 설계된다. 라플라시안 행렬을 이용하여 개체 간의 정보 교류를 정의한 후, 궤환선형화 과정을 거친 비행체에 적용하였다. 또한, 본 논문에서 제안한 제어기의 안정성 해석을 수행하였다. 또한 제안한 제어기의 성능을 검증하기 위해서 회전익 무인기 비행체 모델에 대한 수치 시뮬레이션을 수행하였다.

Considering the impact of buildings beyond their outline to our environment is the first step towards sustainable architecture. As we are still in the early days of sustainable design and its technology, we should make predictions about the design options. architecture activities in project is needed to predict more locally, nationally, globally not only present but future energy demand. The role of the architects who pioneered sustainable design is significantly important, that is to say architects should become a team leader rather than the sole form-giver and come up with the integrated idea related to each field such as the structural, mechanical and electrical engineers includes an energy specialist, in some cases, an independent Design Facilitator. In other words architects have to suggest goals and alternatives for human-being and biodiversity to sustainable life as well as vision of architecture.

Purpose: The objective of this study was to identify relationships among the perception of quality assurance and national hospital evaluation program and nursing performance of hospital nurses. Method: The participants were 401 nurses who worked at the A medical center. The data were collected from 25 April to 9 May. 2008. The cross-sectional descriptive survey was done using a structured questionnaire. Result: The perception of the quality assurance correlated significantly with nursing performance. Also, the perception of national hospital program correlated significantly with nursing performance. However, the scores of perception of quality assurance & national evaluation program of hospital nurses is relatively low. Conclusions: These results means positive perception of quality assurance of nurses can produce good nursing performance. It suggests that nurses need more education and training for quality assurance. And the incentives will be needed to enhance the perception of quality assurance. Moreover, the detailed nursing performance indicators should be developed to measure the quality of nursing performance properly.

GaAs pHEMT 기술로 V-band 수신단 각 MMIC 회로들을 설계 제작하였다. 또한 이를 집적하여 V-band downconverter module을 제작하였다. 제작된 downconverter는 24 dBm의 출력을 내는 LO 구동 전력 증폭기, 20dB의 소신호 이득을 가지는 저잡음증폭기, -1.6dBm의 출력을 내는 active parallel type의 발진기, 6 dB 이상의 변환이득 특성을 나타내는 cascode type의 혼합기로 구성되어 있다. 이처럼 혼합기의 우수한 변환이득 특성은 밀리미터파 대역에서 변환 이득 특성을 키우기 위해 반드시 필요한 거대한 IF buffer amplifier의 필요를 없애 주었다. 완성된 downconverter module의 측정결과 별도의 IF buffer amplifier없이 57.5 GHz와 61.7 GHz 사이에서 20 dB 이상의 높은 변환이득을 얻을 수 있었다.

Constructions sites are affected by Diversity workplace, complexity of construction, Change of place, Mobility of workers and so on. In a single establishment, Prime contractors and subcontractors have to conduct their work at the same time. There are a lot of unpredictable risks when the construction is running, coordination between contractors is very important to do a risk assessment under the condition. Large Construction companies were investigated by previous studies. Survey research is applied to the risk assessment. In the writing, Risk assessment of the entire lower level. Because of the low level of risk factors to find. Also, There was a limit to investigate accidents. Confirmed that Effort to derive a risk factors were desperately of the risk assessment. Results were obtained through previous studies. The PCM is several experts should be joined. Experts Site Manager, Supervisor, Safety Manager, Director Contractor, Work team leader is required to participate. Construction plans, Process Planning to the risk find beforehand. And Determines how the operations and the control. Also, Made it into the database. and PCRA can be used in the risk assessment was developed.

Objectives: The purpose of the study is to investigate the current status and radiographic safety management in Korea. Methods: A self-reported questionnaire was completed by 200 dental hygienists in Jeonbuk province from September 1, 2014 and October 31, 2014. The questionnaire consisted of general characteristics of the subjects, radiation knowledge, radiation safety management, and radiation exposure anxiety. Data were analyzed using SPSS 18.0 program. Results: Duration of clinical experience(r=0.142) and number of daily radiation shot(r=0.145) showed a positive correlation to radiation safety management, and a nrgative correlation to use of intraoral films and digital devices(r=-0.587). A logistic regression analysis was performed in order to evaluate the influence on radiography knowledge. The results showed that the factors had significant influences on the age group over 41 years old(OR 7.25; 95% CI 1.30-40.43) and those who took a position above team leader(OR 0.23; 95% CI 0.59-0.90). Conclusions: It is very important to have the safety management toward dental intraoral imaging and radiograpgic shot in the dental hygienists. Continuous efforts should be emphasized on radiographic safety management and behavior.

Purpose: The purpose of this study was to evaluate the effects of BeHaS exercise program on pain, balance, and falling efficacy in elderly with osteoarthritis. Method: A convenience sample of 52 elderly people with osteoarthritis who lived in C city were recruited through the public health center. For this quasi-experimental study design, 31 of the elders were assigned to the experimental group which received the BeHaS exercise program twice week for eight weeks, and 24 were assigned for the control group (no intervention). Outcome measures were numeric pain scale, standing on one leg for balance, fall efficacy scale. Analysis was performed with SPSS version 12.0 program. Results: Pain was decreased significantly in the experimental group as compared to the control group, Balance and fall efficacy were improved significantly in the experimental group as compared to the control group. Conclusion: The BeHaS exercise program can be effective in improving pain, balance, and fall efficacy in elders with osteoarthritis.

Being flexible, responding and adapting to changes can be valuable. However, they are essentially passive ways of dealing with situations. Creating new values and innovation are more active and effective strategies fora constantly changing environment. As such, most companies in e-business should focus on developing creativity across the board. Employees' creativity has become a critical factor in e-business. This paper explains how to increase workers' creativity through authentic leadership and psychological empowerment. As it is not machines or computers, but people, that are ultimately still responsible for creating novel outcomes, this study emphasizes the overriding importance of members' ability and leader's roles, which greatly influence followers' levels of motivation. Authentic leadership encourages members to reach and display their potential, and enhances their intrinsic motivation. Moreover, members' psychological empowerment is directly associated with both intrinsic motivation and autonomy, preconditions for creativity. Hence, these two dimensions- leadership and an individual's psychological state- will increase workers' creativity, which works to increase performance and create more opportunities not only at the individual level, but also at the team or organization level. The purpose of this paper is to explain the effects of authentic leadership on creativity and the moderating effects of psychological empowerment between authentic leadership and creativity in the e-business environment.
