The purpose of this study is to identify influencing factors for successful introduction, implementation and management of HMRPS through assessment of the employees attitude toward HMRPS in technical, administrative, and organization behavioral areas. Data were collected from 157 HMRPS employee members' self-reporting questionnaire in three university hospitals in the city of Seoul and Kyonggi Province from November 5 to November 10, 1997. Relevant literature on industry company MPR system theory was reviewed to develop the theoretical framework. The results were as follows : The employee's recognition of tangible benefit were more significantly influenced success than intangible benefit for successful operation relating the HMRPS. Concerning the employee's recognition of the successful HMRPS and the factor of influenced success was significantly positive correlation between tangible and intangible benefits and success factor in technical, administrative, and organizational behavior area. This study showed that major factor affecting the employee's recognition of tangible and intangible benefit for successful HMRPS. For tangible benefits : Success factors in the technical areas were quality of the data and information, efficiency of inventory management and rescheduling of operation plan. Success factors in the administrative areas were : role of top management. Success factors in the organization behavioral areas were ; simplicity of the HMRPS, human resistance to change. For intangible benefits : Success factors in the organization behavioral areas were ; user involvement, simplicity of HMRPS, human resistance to change. Furthermore as the exact evaluation of successful factors of HMRPS implement is needed, research for the development of systemic variables of physical distribution system control, methods, capacity of system, duration and other environment in many of 30 hospitals or more, and for the empirical study for HMRPS.

Design of T-S(Takagi-Sugeno) Fuzzy Control Systems Under the Bound on the Output Energy

Kim, Kwang-Tae,Joh, Joog-Seon,Kwon, Woo-Hyen Institute of Control 1999 Transaction on control, automation and systems eng Vol.1 No.1

This paper presents a new T-S(Tae-Sugeno) fuzzy controller design method satisfying the output energy bound. Maximum output energy via a quadratic Lyapunov function to obtain the bound on output energy is derived. LMI(Linear Matrix Inequality) problems which satisfy an output energy bound for both of the continuous-time and discrete-time T-S fuzzy control system are also derived. Solving these LMIs simultaneously, we find a common symmetric positive definite matrix P which guarantees the global asymptotic stability of the system and stable feedback gains K's satisfying the output energy bound. A simple example demonstrates validity of the proposed design method.

Thermoelectric Properties of Bi2Te3 Film Processed by Electrodeposition

Lee, Kwang-Yong,Oh, Tae-Sung Research Institute of Science and Technology HONGI 2005 Hongik Journal of Science and Technology Vol.9 No.-

Thermoelectric properties of the electrodeposited Bi_(2)Te_(3) films have been investigated. Bi_(2)Te_(3) plating solution of 20 mM concentration was prepared by dissolving Bi_(2)O_(3) and TeO_(2) into 1M HNO_(3). Thermoelectric properties of the electroplated Bi_(2)Te_(3) films were changed with the film thickness, and the 40 μm-thick film exhibited Seebeck coefficient of -66 μV/K, electrical resistivity of 2.4 mΩ-cm, and power factor of 1.75x10^(-4) W/K^(2)-m. Using multilayer overhang process, the photoresist pattern to form thermoelectric legs of 30 μm depth and 100 μm diameter was successfully fabricated.

강영수,김동인,이선미,김 임,김태형,은헌정 大韓神經精神醫學會 1998 신경정신의학 Vol.37 No.4

연구 목적 : 임상가를 위한 외상후스트레스장애 척도를 이용하여 교통 사고 후 신체 손상 환자의 외상후스트레스장애의 발병률을 알아보고, 사회인구학적 변인들, 손상 심각도, 불안, 우울과 외상후스트레스장애와의 상호관련성을 고찰하고자 하였다. 방 법 : 104명의 교통사고 환자들을 대상으로 , 자기 보고형인 사고 후 정신 건강에 관한 설문지와 외상후스트레스장애를 진단하기 위해서 임상가를 위한 외상후스트레스장애 척도를 이용하여 면담을 실시하였으며, 손상 심각도 척도를 이용하여 신체 손상의 정도를 측정하였다. 결 과 : 외상후스트레스장애의 발병률은 61.5%이었으며, 사회인구학적 변인들과 손상 심각도 점수에서는 외상후스트레스장애군과 비 외상후스트레스장애군이 유의한 차이를 나타내지 않았다. 그러나 외상후스트레스장애 군에 속한 사람들이 사고 당시에 사망자나 부상자를 목격한 경우가 의미있게 많았고(χ²=8.48, p<0.05). Beck의 우울점수가 외상후스트레스장애군에서 유의한 증가를 보였다.(t=5.03, p<0.05). 결 론 : 교통사고 후 외상후스트레스장애의 발병률은 매우 높았고, 두 집단 모두가 정상인 보다 훨씬 더 높은 불안과 우울을 보고하고 있다. 이와 함께 연구 결과는 상황에서 사망자와 부상자의 목격시 외상후스트레스장애로 발병하게 하는 위험 요인 중 하나 일 수 있다. Objectives : the authors attempted to estimate the incidence of posttraumatic stress disorder (PTSD) and the differences of sociodemographical feature, injury severity, depression and anxiety between PTSD and non-PTSD groups after motor vehicle accident. Methods : The subjects were 104 patients who had undergone motor vehicle accidents, and been hospitalized to orthopedic surgery hospitals. We administered them clinician-administered PTSD scale(CAPS) for diagnosing PTSD, injury severity scale(ISS) for identifying their physical injury, self-reported questionnaire made to identify socioepidemographic data, Beck Depression Inventory(BDI) for measuring depression, and State Trait Anxiety Inventory Ⅰ,Ⅱ(STAI-Ⅰ,Ⅱ) for measuring anxiety. Results : The incidence of PTSD in subjects was 61.5%. Most of sociodemographic factors were not different between PTSD and non-PTSD groups. Only there were significant differences between PTSD group and non-PTSD group on the cases that observed the dead or the wounded at the scene of motor vehicle accident(χ²=8.478, p<0.05) and BDI(t=5.03, p<0.05). Conclusion : These results indicate that prevalence of PTSD is higher after motor vehicle accident and both of the two groups report much higher depression and anxiety than normal population. In addition, the results of this study show that the observation of dead or wounded at accident situation can be one of risk factors to precipitate PTSD.

정광태,송복희 한국기술교육대학교 2006 論文集 Vol.13 No.1

Character is one of the most important high value-added industries in 21 century. Various analyses on character are required to raise customer's satisfaction on character products. In this study, we proposed application method of factor analysis, cluster analysis, multi-dimensional scaling and application cases. From the factor analysis, aesthetic factors on character could be decided and image maps with aesthetic factors could be obtained. From the cluster analysis, characters could be grouped by its aesthetic characteristics. From the multi-dimensional scaling, a direction of character design could be decided. Finally, it is concluded that multi-variate analysis should be effectively applied to character design.

This study aims to develop using a continuous removal of organic and settling solid(CROSS) to increase the efficiency of aeration system for wastewater treatment. To solve many problems of the conventional activated-sludge process, authors suggested a new CROSS model in conjunction with aeration systems in 1996. This system is characterized by utilizing an intensive aeration pipe with inlets at the lower portion and outlets at the higher portion in an aeration tank. Through the experiments on CROSS process, the average removal efficiences of BOD, COD_(Mn), SS, T-N and T-P were showed 98.8%, 93.9%, 98.0%, 71.3% and 49.8%. The average DO (Dissolved-Oxygen) concentration was constantly maintained at 8.0 mg/L by the intensive aeration which was accompanied by rapid reduction of BOD. Degradation of the organic matters in sewage then continued for the whole aeration period. The process demonstrated that it was very adaptive without seeding and returning the sludge. Compared to the activated sludge system, the system was very flexible for the continuous flow treatment. This preliminary assessment showed that the porous media in CROSS reactor is viable for the sewage treatment, since the porous media under the intensive aeration achieves acceptable effluent quality.
