Purpose: The purpose of this study was to investigate the extended job of paramedic after the 1st job description in 2000 by the National Health Personnel Licensing Examination Board. Methods: This study was carried out from May 2012 to July 2013 on the Developing A Curriculum (DACUM) method to analysts 330 responses among 400 questionnaires (response rate 82.5%) after analysing 30 pilot questionnaires. In order to enhance validity and reliability of this job description, 2 job analysts in universities and 10 EMT-Paramedics in hospitals and fire stations were recruited. Results: There were differences between 166 (year 2000) and 240 (2012) in task element. There were higher answering at triaging patient(2.64 frequency, 4.15 importance), calling for help(2.68 frequency, 4.07 importance) in disaster emergency care. There were higher answering at measuring vital sign (3.95 frequency, 4.22 importance), measuring ECG(3.84 frequency, 4.14 importance), wound care(3.48 frequency, 3.86 importance), bleeding control & wound care(3.46 frequency, 3.86 importance), applying $O_2$(3.40 frequency, 3.94 importance) in physician assistant. Conclusion: Scope of extended practice as a physician assistant in hospital setting recommended us to replace the present curriculum and national exam with new curriculum and national written & skill test.

Death of spouse is the most heartbreaking stressful and inevitable tragic life event. In middle aged men who belong to the social middle class and accomplished their occupational success, experiences of spousal bereavement are great shock. The aim of this study was to find out how they overcome their mental and physical pain and to obtain the basic materials to develop suitable nursing care programs for them. The methodological approach of this study is Giorgi's phenomenological analysis meaning unit. This method also makes theme focal meaning, situated structural description and create general structural description grasped by participator's experience through situated structure description. This study performed from November 2002 to May 2004, and participators were four men. Data collected through in-depth personal interviews. which had been tapped and analysed the Giorgi's method. Finally, the five focal meaning below have been abstracted. Theme 1. Physical symptom loss of appetite, fatigue, insomnia. outbreak of illness, weight loss. Theme 2. life of spiritless lack of desire, sense of emptiness, unstableness, prosaic life. wandering. indifference of appearances, avoidance of meeting people. Theme 3. life of retrospction reflection for his wife, yearning, grief, muttering to himself, never-to-be forgotten wife, leading a lonely life. Theme 4. negative emotion reproaching, feeling hurt, marriage of daughter, feeling heavy, getting angry, sexual desire, awareness of his sinfulness. loneliness Theme 5. social support and adjustment getting his wife off his mind, curring favor with children, support and consolation by his daughter-in-law, appreciation for hospice nurse, considering remarriage, taking care of himself, good relation with his children. The result of this study showed that middle aged men bereaved of their wife by cancer need other's concern. And we have to study further to understand their experience. Until now hospice nursing is concentrated on cancer patients But from now we have to provide their families suitable nursing care programs to adjust themselves to social life before and after death of patients.

본 논문에서는 HMM 기반의 연속음성인식에서 음향모델의 최적화 기법을 논한다. 대부분의 음성인식 시스템에서 HMM 상태별로 동일한 개수의 가우시안 성분 (mixture component)을 사용해 왔다. 그러나, 음향 모델링에 사용되는 데이터 샘플의 개수는 HMM상태별로 다르므로 이에 따른 최적화를 수행할 경우 모델 파라미터의 개수를 효과적으로 줄일 수 있을 뿐 아니라, 디코딩 단계에서 음성인식기의 속도 및 인식 성능 개선이 기대된다. 본 연구에서 제안한 방법은 기존에 알려진 MDL (minimum description length) 기반의 음향모델 최적화 방법에서 가우시안 성분들의 통합과정에 가우시안 성분의 가중치 정보 (mixture weight)를 반영하도록 개선하였다. 인식 실험 결과, 제안한 방법은 가우시안 성분의 가중치를 반영하지 않는 기존 방법에 비해 향상된 최적화 성능을 보임을 확인할 수 있었다.

In the present study, an advanced surface construction method based on NURBS surface scheme is proposed to construct the extrusion die surface. The inlet and outlet profiles we precisely described with NURBS curves using the cubic appropriate control points and weights. The interior control Points of surface are generated using the cubic interpolation of the weights at the inlet and outlet sections. In order to verify of the proposed method, automatic surface generation is carried out for the various types of extrusion die surface.

For shape description, a fast sequential method for polygonal approximation of chaincoded plane curves which are object boundaries is proposed. The proposed method performs polygonal approximation by use of the distance error from one point to a line, and its performance is enhanced by the smoothed slopes of lines. Furthermore, accumulated distance error and variable distance error threshold are proposed in order to consider and implement the visual characteristics of the human being.

In this paper, discrete-time H$_{\infty}$ controller design in .delta.- domaion using Normalized Coprime Factor plant description is proposed and the loop-shaping method developed by Mcfalane[2], which is known to be very simple and systematic method, is adopted here in H$_{\infty}$ controller design. In particular, we show that .delta.- H$_{\infty}$ controller proposed here is a unified form for the continuous and discrete-time cases.es.

In this paper, we propose a fake-iris detection method. In order to detect the fake-iris, we measure physiological features which are the reflectance ratio of the iris to the sclera at 750 nm and that at 850nm. In order to classify live and fake iris features, we use support vector data description (SVDD). From our experimental results, it is clear that our fake-iris detection method achieves high performance when distinguishing between a live-iris and a fake-iris.

This paper deals with modeling and scheduling for flexible manufacturing systems(FMS). In modeling extended Petri nets are used to describe various and complex properties. To resolve multiple conflict without predefined properties, such as part selection, machine selection, rule-based scheduling method is introduced. This structure have a capability of on-line scheduling with systematic modeling description.
