The process of physical therapy uses a problem-solving approach to enhance a patients's functioning status. The International Classification of Functioning, Disability and Health(ICF) is the common concept for the functioning in the world. Physical therapists require the ability to identify problems, formulate hypothesis, and plan intervention strategies through clinical reasoning. In the clinical process, physical therapists need to use standard and common languages in speech and in documentation. The purpose of this study was to suggest the process of making strategy for efficient intervention, examining and evaluating the functional problem of the person with stroke using ICF tools. For the first step in this process model, therapists could list the information relating to functional problems used by the ICF Core set and then could identify the interaction among the problems using the ICF assessment sheet. For the next step, therapist is needed to make the hypothesis and hypothesis testing, and then set a primary functional goals and therapeutic goals in detail after prioritizing the problems to be managed based on the problem list. Finally, after setting the identified problems as the purpose of intervention through the hypothesis testing, therapist could do some intervention after making a plan to solve these problems, and find out the outcomes using the ICF evaluation display. This report illustrates how to apply the process based on ICF concept into physical therapy practice. Making a decision for the most efficient intervention requires that therapists use the clinical reasoning process based on ICF concept.

Our faces can express a remarkable range of subtle emotions and silent messages. Because the face is so essential for complex social interactions that are part of our everyday lives, aesthetic repair and restoration of function are an important tasks that we must not take lightly. Soft-tissue defects occur in trauma patients and require thorough evaluation, planning, and surgical treatment to achieve optimal functional and aesthetic outcomes, while minimizing the risk of complications. Recognizing the full nature of the injury and developing a logical treatment plan help determine whether there will be future aesthetic or functional deformities. Proper classification of the wound enables appropriate treatment, and helps predict the postoperative appearance and function. Comprehensive care of trauma patients requires a diverse breadth of skills, beginning with an initial evaluation, followed by resuscitation. Traditionally, facial defects have been managed with closure or grafting, and prosthetic obturators. Sometimes, however, large defects cannot be closed using simple methods. Such cases, which involve exposure of critical structures, bone, joint spaces, and neurovascular structures, requires more complex treatment. We reviewed and classified causes of significant trauma resulting in facial injuries that were reconstructed by microsurgical techniques without simple sutures or coverage with partial flaps. A local flap is a good choice for reconstruction, but large defects are hard to cover with a local flap alone. Early microsurgical reconstruction of a large facial defect is an excellent choice for aesthetic and functional outcomes.

옥수수는 전세계적으로 다양한 형태로 소비되는 3대 식량작물로, 영양성분은 대부분은 전분으로 구성되어 있지만, 다량의 기능성 성분도 포함되어 있다. 옥수수는 형태적으로 찰옥수수, 단옥수수, 종실옥수수로 나뉘는데, 각 품종마다 쓰임이 다르기 때문에, 영양성분에서도 차이가 나타난다. 본 연구는 옥수수의 기능성 성분 함량을 분석하고 환경적 요인을 고려하여 자연변이 데이터를 생산하기 위해 수행하였다. 국내 3개지역(수원, 대구, 홍천)에서 재배한 옥수수 3가지 형태의(찰옥수수, 단옥수수, 종실옥수수) 시료를 수집하고, HPLC 및 GC-TOF-MS를 이용하여 성분을 분석하였다. ANOVA 및 다변량 통계분석, Pearson 상관분석을 통해, 형태별 그룹으로 비교하였을 때, 총 32개의 성분 항목 중 28개의 성분 항목이 유의적 차이를 보였으며(p<0.05), 지역별 그룹으로 비교한 결과, 15개의 성분이 유의적 차이를 보였다. 다변량 분석결과, 지역별보다 형태별로 군집 구분이 뚜렷하게 형성되었는데, 형태별 군집 형성 주요하게 기여한 성분은 α-carotene, lutein과 δ-tocopherol이었다. 본 연구에 따르면, 옥수수 기능성 성분은 환경적 요인보다 유전적 요인에 의해 영향을 더 많이 받는 것으로 사료된다. 자연변이 데이터는 옥수수 기능성 소재 연구분야 및 생명공학작물의 식품학적 안전성 평가시 기초자료로 활용될 수 있다.

This dissertation is about a study on the space planning of take-out coffee shops grouped by type. The classification is based primarily on stand-alone shop, which runs independently, and shop in shop, located inside of another shop with different industry. And its subdivision is characterize by 3 types: Combination type has not only space to enjoy coffee as we can usually see in conventional coffee shops, but also a counter where take-out coffee is served. Separation type has space for drinking coffee and an external booth for easy buy. Booth type is a booth itself or driving (cruising) booth. In conclusion, some take-out coffee shop are exampled and space analysis is made with analytic tools, such as people of preference, location evaluation, functional space division, dimension per person, and planning of traffic line.

The results of the clinical observations on the 158 cases of the mitral valvular heart disease treated at the Department of Thoracic and Cardiovascular Surgery, Masan Koryo General Hospital from June, 1986 to December, 1991 were as follows; 1. There were 50 men and 108 women with sex ratio 1: 2.2. 2. The age of patient varied widely from 13 years to 65years. 3. The preoperative functional level accoridng to the NYHA classification were class II, III, IV in 18%, 67%, 15%. 4. All 158 patients were operated on under direct vision using extracorporeal circulation, mitral valve replacement in 118 cases, mitral and aortic valve replacement 40 cases. 5. The follow up period was between 2 months and 65 months postoperatively. [mean 30.1 months] 6. The early operative motality was 5.7%[9 cases], late motality was 4%[6 cases]. 7. The cardiothoracic ratio in the chest X-ray decreased at the 6th month postoperation. [pre-op: 0.60$\pm$0.07, post-op: 0.56$\pm$0.06 p<0.01]

In this article, we introduced the estimation method by 'Safety Integrity Level'(SIL) for the criterion of safety assurance and performed a case study on a flame scanner. SIL requires probabilistic evaluation of each set of equipment used to reduce risk in a safety related system. FMEDA(Failure Modes, Effects and Diagnostic Analysis) method is widely used to evaluate the safety levels and provides information on the failure rates and failure mode distributions necessary to calculate a diagnostic coverage factor for a part or a component. Basically, two parameters resulting from FMEDA are used for SIL classification of the device : SFF(Safe Failure Fraction) and PFD(Probability of Failure on Demand). In this case study, it is concluded that the flame scanner is designed to fulfill the condition of SIL 3 in the aspect of SFF and PFD.

This paper presents a method that automatically recognizes dimension sets from the mechanical drawings, and that classifies 6 types dimension sets according to functional purpose. In the proposed method, the object and closed-loop symbols are separated from the character-free drawings. Then object lines and interpretation lines are vectorized. And, after recognizing dimension sets(consistings of arrowhead, shape line, tail lines, extension lines, text-string, and feature control frame), we classify recognized dimension sets as horizontal, vertical, angular, diametral, radial, and leader dimension sets. Finally the proposed method converts classified dimension sets into AutoCAD data by using AutoLisp language. By using the methods of geometric modeling, the proposed method readily recognized and classifies dimension sets from complex drawings. Experimetnal results are presented, which are obtained by applying the proposed method to drawings drawn in compliance with the KS drafting standard.
