보건의료의 질 제고를 위한 보건의료 수요 및 공급 체계 개선 : 근로생활의 질을 중심으로
김동건,김병섭 서울대학교 행정대학원 2000 行政論叢 Vol.38 No.2
보건의료서비스의 질 제고는 수요측면과 공급측면에서 살펴볼 수 있는데, 지금까지 많은 의료보건정책 연구는 주로 보건의료서비스 공급측면에 치중된 연구를 해왔다. 본 연구는 다소 소홀하게 취급되어 왔던 수요측면에 초점을 맞추어, 보건의료에 대한 수요 자체를 줄여서 궁극적으로 의료보건 분야의 삶의 질을 제고하고자 한다. 보건의료 수요에 영향을 미치는 요인들은 교통사고, 환경악화등 여러 가지가 있지만 그 중에서 특히 우리 인간 생활의 거의 반을 차지하는 근로와 관련하여 발생하는 의료 수요를 줄이는데 주목하였다. 분석결과 근로생활의 질이 질병 또는 육체적 증상에 영향을 미치고 있다는 것을 확인하였다. 그리고 근로생활의 질은 직업안정성과 역할갈등 및 업무과다, 그리고 보상의 공정성과 조직내 집권화와 관계있는 것으로 나타났다. 이를 토대로 근로생활을 질을 제고하기 위한 처방을 제시하였다.

This study was undertaken to analysis the forward pike somersaulting in 3m spring board diving with cinematographic method & to suggest quantifying material for performance in spring board diving. The subjects participated in the experiment were consisted of male athlete(2) & female(2) representing CheJu Do. The conclusions obtained were as follows; 1. In temporal analysis, elapsed time in air-phases was the longer, and factors influencing significantly in spring board was consisdered to be touch-down, take-off position, velocity. 2. In vertial & horizontal velocity components, factors influencing significantly in spring board was considered to be horizontal & vertical velocity at the release instant, the number of rotation, touch-down, and take-off position, therefore it was important factors absolutely distributing to horizontal & vertical components. 3. In angular displacement, as the number of rotation, the relative angle between thigh and trunk was higher. therefore it was necessary to decrease moment of inertia for more rotation. 4. In angular velocity, it as thought that Succession in the air-phase depend upon the touch-down in board & initial condition, decrease of moment of inertia according to increase of rotation in release in board. 5. In total angular momentum, The more stable variation in function of time, The more stable angular momentum was, the more deviation of it, the more unstable performance was. 6. Angular momentum of body segments from release on board to max. height was showed little relatively in constraint to entering, larger contribution of relative angular momentum. 7. There was a difference of kinetic variables among each rotations but common conclusions was needed to more short, instantaneous vertical component, less vertical angle, larger depression of board, larger local angular momentum. in 3m spring board.
Linearly Constrained Adaptive Array Processing with Alternate Mainbeam Nulling
Byong Kun Chang,Chang Dae Jeon,Dong Hyuk Song 한국전자파학회JEES 2008 Journal of Electromagnetic Engineering and Science Vol.8 No.2
This paper concerns with signal cancellation problem in a linearly constrained adaptive array processor in coherent environment. Alternate mainbeam nulling approach was proposed to prevent the signal cancellation phenomenon. The linearly constrained LMS algorithm with a unit gain constraint and that with a null constraint in the direction of the desired signal is alternately implemented to reduce the signal interaction between the desired signal and the interferences, which is the main cause of the signal cancellation. It is shown that the proposed method performs better than a conventional method.
General Linearly Constrained Broadband Adaptive Arrays in the Eigenvector Space
Chang, Byong Kun The Korea Institute of Information and Commucation 2017 Journal of information and communication convergen Vol.15 No.2
A general linearly constrained broadband adaptive array is examined in the eigenvector space with respect to the optimal weight vector and the adaptive algorithm. The optimal weight vector and the general adaptive algorithm in the eigenvector space are obtained by eigenvector matrix transformation. Their operations are shown to be the same as in the standard coordinate system except for the relevant transformed vectors and matrices. The nulling performance of the general linearly constrained broadband adaptive array depends on the gain factor such that the constraint plane is shifted perpendicularly to the origin by an increase in the gain factor. The general linearly constrained broadband adaptive array is observed to perform better than a conventional linearly constrained adaptive array in a coherent signal environment, while the former performs similarly to the latter in a non-coherent signal environment.
Optimum Design of Thinned Microphone Arrays Using a Modified Perturbation Approach
Chang, Byong-Kun The Acoustical Society of Korea 1998 韓國音響學會誌 Vol.17 No.e4
A modified perturbation method is proposed to optimize the beam pattern of thinned microphone arrays. Both microphone spacing and array weight are iteratively adjusted via successive perturbation to achieve an optimum beam pattern in a Dolph Chebyshev sense. To improve the sidelobe performance, an alternative perturbation with respect to microphone spacing and array weight is implemented. Also, a linear space-tapering is employed in the perturbation process. It is demonstrated that the proposed approaches successfully yield sidelobe performances comparable to that of a normal array. Computer simulation results are presented.
Optimum Array Processing with Variable Linear Constraint
Chang, Byong Kun The Korea Institute of Information and Commucation 2014 Journal of information and communication convergen Vol.12 No.3
A general linearly constrained adaptive array is examined in the weight vector space to illustrate the array performance with respect to the gain factor. A narrowband linear adaptive array is implemented in a coherent signal environment. It is shown that the gain factor in the general linearly constrained adaptive array has an effect on the linear constraint gain of the conventional linearly constrained adaptive array. It is observed that a variation of the gain factor of the general linearly constrained adaptive array results in a variation of the distance between the constraint plane and the origin in the translated weight vector space. Simulation results are shown to demonstrate the effect of the gain factor on the nulling performance.
General Linearly Constrained Narrowband Adaptive Arrays in the Eigenvector Space
Chang, Byong Kun The Korea Institute of Information and Commucation 2017 Journal of information and communication convergen Vol.15 No.3
A general linearly constrained narrowband adaptive array is examined in the eigenvector space. The optimum weight vector in the eigenvector space is shown to have the same performance as in the standard coordinate system, except that the input signal correlation matrix and look direction steering vector are replaced with the eigenvalue matrix and transformed steering vector. It is observed that the variation in gain factor results in the variation in the distance between the constraint plane and the origin in the translated weight vector space such that the increase in gain factor decreased the distance from the constraint plane to the origin, thus affecting the nulling performance. Simulation results showed that the general linearly constrained adaptive array performed better at an optimal gain factor compared with the conventional linearly constrained adaptive array in a coherent signal environment and the former showed similar performance as the latter in a noncoherent signal environment.
