Y. R$\acute{e}$ball$\acute{e}$ [11]교수는 쇼케이적분 기준에 의한 필요측도의 표현에 관해 조사한다. 또한 쇼케이적분 표현관 관련된 필요측도의 순위를 결정 연장을 생각한다. 이 논문에서, 우리는 결정연장이 쇼케이 기대효용에 따른 애매한(구간치로 명명함) 필요측도를 가지는 경우를 생각한다. 더욱이, 구간치 필요측도에 대한 단조 집합치 함수를 갖는 기호에 대한 약 쇼케이적분표현과 필요측도에 대한 구간치 효용함수를 갖는 기호에 대한 강 쇼케이적분 표현에 대한 두 가지 정리를 증명한다.

Y. R$\acute{e}$ball$\acute{e}$[Fuzzy Sets and Systems, vol.157, pp.3025-2039, 2006] discussed the representation of necessity measure through the Choquet integral criterian. He also considered a decision maker who ranks necessity measures related with Choquet integral representation. Our motivation of this paper is that a decision maker have an "ambiguity" necessity measure to present preferences. In this paper, we discuss the representation of interval-valued necessity measures through the Choquet integral criterian.

We examined an urban population's awareness of dietary guidelines to determine whether they perceived them to be necessary, and identified the factors affecting this awareness and perceived necessity. Data were collected via physical examinations and face-to-face interviews. Health indicators were collected from health examinations, and information on individual characteristics, including awareness, perceived necessity, and dietary status were obtained from the interviews. The subjects' sociodemographic, health and dietary status were examined as potential factors influencing awareness and perceived necessity. Descriptive statistics, contingency tables, and logistic regression modeling were used in the analysis. Low awareness of the dietary guidelines was displayed by the elderly and poorly educated individuals, and those without a spouse. Most people who were not aware of the dietary guidelines thought the guidelines unnecessary. Males with hypertension and lower hemoglobin levels, and females with less education had low awareness. Elderly females with lower bone density had less perceived necessity. Males and females with poor dietary status reported low perceived necessity.

We present here two Petri nets formalisms that can deal with uncertainty by the use of necessity-valued logic. The first and basic model, called necessity-valued Petri nets (NPN), can at the same time deal with uncertainty on markings are on transitions. The second model, called necessity-valued Petri nets (TNPN), is an extension of both NPN and timed Petri nets.

A semantics for logical necessity, based on Carnap's criterion of adequacy, is given with respect to the ontology of logical atomism. A calculus for sentential (propositional) modal logic is described and shown to be complete with respect to this semantics. The semantics is then modified in terms of a restricted notion of 'all possible worlds' in the interpretation of necessity and shown to yield a completeness theorem for the modal logic S5. Such a restricted notion introduces material content into the meaning of necessity so that, in addition to atomic facts, there are "modal facts" that distinguish one world from another.

이 글은 그레이엄 (A. C. Graham)이 후기묵가의 저작인 "묵경"에서 보이는 필(必)과 선지(先知)를 각각 '논리적 필연성'과 '선험적 지식'(a priori knowledge)으로 보는 해석을 비판하기 위한 것이다. 그레이엄은 묵가의 논리학을 '이름과 대상을 짝짓는' '기술의 학'(論)과 '이름과 이름간의 관계를 따지는' '추론의 학'(辯)으로 나누고 특히 후자에 대해 비록 그것이 서구의 형식논리학은 아니지만, 유클리드 기하학과 같은 엄밀한 증명의 과정으로 보아야 한다고 하였다. 이러한 그의 주장들은 지식을 그 대상에 따라 명지(名知)와 합지(合知)로 나누어보는 데서 출발한다. 그러나 내가 보기에 기술의 학과 이름의 학은 후기묵가의 저작인 "묵경"안에서 명확히 구분될 수 없고, 게다가 묵가의 선지(先知)와 이 선지(先知)가 가진 필연성은 기본적으로 논리적 필연성이 아니라 규범적 필연성 및 경험적 필연성의 개념이다. 규범적 필연성은 중국의 정명(正名)사상에서 제시된 '규범적 정의이론'으로부터 기인하는 것이다. 규범적 정의이론이란 기술적 정의이론과는 달리 규범적으로 개념을 정의하는 것이다. 예컨대 '아버지는 자애롭다'의 정의는 형태는 기술적이나 사실은 '아버지는 자애로워야한다'의 규범적인 것이다. 이러한 규범적 정의이론을 통해 경험적 지식은 그것이 지식인한 당연히 필연적으로 오류 불가능임이 주장된다. 한마디로 묵가에서는 경험적 지식이 추론적 지식 혹은 선험적 지식보다 항상 더 우선적이기에 묵가의 선험적 지식은 사실 엄밀하게 선험적인 것이 아니고, 이러한 지식이 갖는 필연성도 규범적 필연성 및 경험적 필연성에 불과하다.

This study was conducted to evaluate the necessity of clinical nutrition education in the medical school curriculum. One hundred and eighty five medical school students, residents, nurses, and forty undergraduate students majoring in food science and nutrition were involved in this study. The survey included questions about nutritional knowledge, necessity of nutrition counseling, necessity of clinical nutrition and nutritional attitudes. The nutritional knowledge scores of the subjects in medical school and residents were significantly lower than those of the students majoring in food science and nutrition. Subjects of 91.3% strongly agreed to the necessity of nutrition counseling for patients ; 78.9% agreed that the present nutrition education in medical schools was inadequate. Most subjects (94.1%) agreed that clinical nutrition was an important field in the treatment of diseases. The medical profession is facing the challenges of the 1990s with the shift to outpatient care and preventative services. Clinical nutrition is an essential element in the process of curriculum change. The nutrition educator will be expected to take a leading role in integrating clinical nutrition into medical school curriculum.

Purpose : The objective of this study was to investigate the basis for effective introduction of home visiting physical therapy to provide basic information. Thus in our study, we investigated awareness, necessity and operation plan of home visiting physical therapy for patients and guardian. Method : We conducted a survey 172 and guardian. The questionnaire consisted of items for general characteristics, awareness, necessity and operation plan. Data was collected from 2013 november 1 to november 30. Based on the collected data of self-administered questionnaires, we analyzed for frequency of each questionnaire about awareness, necessity and operation plan of home visiting physical therapy. Result : The awareness for home visiting physical therapy. The necessity for home visiting physical therapy indicated a high result. The result for operation plan indicated a national program. Conclusion : Improving on people's awareness is needed, because the awareness about home visiting physical therapy was low but the need was high. In addition, government institutional arrangements will be needed for advanced medical services as soon as possible.

Purpose: The purposes of this study were to examine the differences in need, necessity, performance, barriers, and effectiveness of workers' health promotion program and to determine the influencing factors in effectiveness of workers' health promotion program by business types. Methods: Subjects were participants of an education held by Korean association of occupational health nurses and a survey was self-reported. Survey items were developed by researchers through literature review. It included general characteristics of occupational health providers and worksites, need, necessity, performance, barriers and effectiveness of workers' health promotion (WHP) program. The total number of worksites was 168, manufacturing/construction was 76 (45.2%), other services were 52 (31.0%), and healthcare services were 40 (23.8%). We used ${\chi}^2test$, ANOVA test, correlation analysis, and multiple regression analysis. Results: There were differences in need, necessity and performance of WHP by business types. In healthcare services, WHP had statistically significant effectiveness to reduce turnover rates. And the influencing factors of WHP's effectiveness were workers' need in manufacturing/construction, health provider's career in other services, and perceived necessity in healthcare services. Conclusion: Based on this result, we propose differentiated strategies depending on the business types for effective workers' health promotion program.
