This study was designed to identify a more effective method of nursing interview in gathering informations by comparing the two, the structured and unstructured methods. May through October, 1976, 40patients on psychiatric wards of Korea University Hospital and National Mental Hospital, Seoul, were sampled and interviewed on their admission/within one week of admission. Both methods were used simultaneously by different interviewers ; 48 hour interval were kept between the two approaches of interview. Contents of informations gathered were grouped according to the criteria developed by the researcher, frequency, percentile score and the means were scored, and the two methods were compared; the amount of information gathered, number of questions used, time spent and the general response towards the methodologies. Results of the study are summarized as follows ; 1. 1. 5 times as many informations were gathered through the structured interview. (1366 ; 849) 2. 68.32% of informations gathered through the unstructured interview and 42.46% of the structured interview revealed to be overlapping; through structured interview, more unique informations (57.54%) were gathered. 3. The average of 33.25 minutes were consumed for the structured interview while 95, 50 minutes for the unstructured. Much higher time consumption is revealed in the unstructured. 4. Majority of patients showed positive response towards both approaches of interview (90% each), however, interviewers responded to experience of certain degree of tension (stress) in the unstructured method (35%) 5. The average of 0.88 question were used to gather one information in the structured while 1.87questions for the unstructctured were used. 6. The average of 0.97 minutes were consumed to gather one information in the structured while 4.50minutes for the unstructured. 7. The average of 1.11 minutes were consumed for one question for the structured while 2.41 minutes for the unstructured. The results of the study revealed that the structured interview were more effective in gathering informations; a larger quantity of informations were gathered in shorter time. Recommendations for further in investigations are as follows ; 1. Comparative analysis of informations gathered through the two methods by experienced professional nurse- interviewers is recommended. 2. Comparative analysis of the quality of informations is recommended. 3. Comparative analysis of the interviewing process (interactions) in relation to the characteristics of patients'health problems is recommended.

새로운 정보기술의 생명주기는 점점 작아지고 그 기술이 점차 복잡해짐에 따라 그 기술을 이해하기가 어려워진다. 본 연구의 목적은 객체 지향 기술의 채택에 관한 이해를 돕기 위하여 객체지향 기술이 전통적인 소프트웨어 프로세스 기술과는 다른 패러다임의 기술이기 때문에 프로세스 중심의 구조지향 기술로부터 영향을 받을 것으로 판단된다. 본 연구는 구조지향 방법이 객체지향 방법론에 미치는 지식간섭 현상을 일종의 2$\times$2 팩토리얼 유사 실험계획법을 사용하여 실증적으로 분석하였다. 구조지향 방법론과 객체지향 방법론을 사용한 기간을 2개의 독려변수로 선택하였고 객체지향 방법론에 대한 사용 편의성을 1개의 독립변수로 설정하였다 자료는 현재 활동중인 구조지향 및 객체지향 방법론에 모두 경험이 있는 자료처리와 관리협회(DPMA : Data Processing and Management Association) 회원으로부터 수집하였다 최종 결과는 구조지향 방법론의 경험이 객체지향 방법론의 사용편의성에 부의 영향을 주는 것으로 나타났다. 향후 연구과제로 문화가 다른 국가에서 유사한 연구 수행한 후에 그 결과를 비교하는 것도 의미가 있을 것이다.

Competencies of entry-level pharmacists are evaluated by multiple-choice questions (MCQ) examination and objective structured clinical examination (OSCE). OSCE helps to evaluate student's communication skills and attitudes, which are difficult to evaluate by the MCQ exam. In Korea, pharmacy OSCE is not implemented; however, the needs of OSCE is growing. This study proposed OSCE exam contents and exam methods that can be implemented in colleges of pharmacy. Further study is needed to develop OSCE scenarios and questions, validate examination questions and evaluation methods by performing a pilot study, and provide feedback on the curriculum and study methods.

This study was motivated how it might be possible to validate structured sampling with orthogonal array for optimal design of a pin. The Taguchi method by orthogonal array, one of the structured sampling methods, has much advantage that is row cost and time saving for experiments. But this method has been applied in limited areas especially for mechanical problems. In this study, we experimented whether the structured sampling is useful for applying optimal design of mechanical elements. For the experiment, we first set up a mechanical problem which was related to determining optimal parameters associated a pin's crack occurred inside a hole. We, then, calculated combination of...

노드는 문서를 구성하는 작은 크기의 의미 있는 정보 단위이다. 정보검색에 문서의 구조정보를 이용함과 더불어 문서보다 작은 검색단위에 대한 연구가 활발히 이루어지고 있다. 이 연구에서는 노드정보를 이용한 검색실험을 위해 벡터공간모델 검색기법을 사용하여 다양한 유사도 산출방식을 적용한 실험과 구조정보를 활용한 확장 실험을 수행하였다. 실험결과 문서의 유사도를 산출하는 방식에 따른 검색성능의 차이는 거의 나타나지 않았으며, 구조정보를 적용하는 확장 노드검색이 가장 좋은 성능을 나타냈다.

One of the important research issues in mobile robot is how to detect the 3D environment fast and accurately, and recognize it. Sensing methods of utilizing laser structured light and/or stereo vision are representatively used among a number of methodologies developed to date. However, the methods are still in need of achieving high accuracy and reliability to be used for real world environments. In this paper to implement a new robotic environmental sensing algorithm is presented by combining the information between intensity image and that of laser structured light image. To see how effectively the algorithm applied to real environments, we developed a sensor system that can be mounted on a mobile robot and tested performance for a series of environments.

The purpose of this paper is the derivation and development of the new definitions and methods for the new estimation of robustness for the systems having structured uncertainties. This proposition adopts the theoretical analysis of the Lyapunov direct methods, that is, the sign properties of the Lyapunov function derivative integrated along finite intervals of time, in place of the original method of the sign properties of the time derivative of the Lyapunov function itself. This is the new sufficient criteria to relax the stability condition and is used to generate techniques for the robust design of control systems with structured perturbations. The systems considered are assumed to be nominally linear, with time-variant, nonlinear bounded perturbations. This new techniques demonstrate the improvement of robustness bounds from the numerical results.

In this paper we compare parameter estimation by Grassmann manifold optimization and sequential candidate set algorithm in a structured principal fitted component (PFC) model. The structured PFC model extends the form of the covariance matrix of a random error to relieve the limits that occur due to too simple form of the matrix. However, unlike other PFC models, structured PFC model does not have a closed form for parameter estimation in dimension reduction which signals the need of numerical computation. The numerical computation can be done through Grassmann manifold optimization and sequential candidate set algorithm. We conducted numerical studies to compare the two methods by computing the results of sequential dimension testing and trace correlation values where we can compare the performance in determining dimension and estimating the basis. We could conclude that Grassmann manifold optimization outperforms sequential candidate set algorithm in dimension determination, while sequential candidate set algorithm is better in basis estimation when conducting dimension reduction. We also applied the methods in real data which derived the same result.

This paper proposes the methods to construct the tree-structured database and analyze the distribution system network. In order to cope with an extensive amount of data and the frequent breaker switching operations in distribution systems, the database for system configuration is constructed using binary trees. Once the tree-structured database has been built, the system tracing of distribution network can be rapidly performed. This remarkably enhances the efficiency of data search and easily adapts to system changes due to switching operations. The computation method of fast power flow using tree search strategies is presented. The methods in the paper may be available in the field of distribution system operation.
