In this paper, concepts of quasi-normal and dually quasi-normal relations are introduced. Characterizations of these relations are obtained. In addition, particulary we show that the anti-order relation ${\nleqslant}$ ($={\leqslant}^C$) is a (dually) quasi-normal relation if and only if the partially ordered set (X, ${\leqslant}$) is an anti-chain.

The evaluation of the Fuzzy Expected Value (FEV) as a typical value requires complete knowledge about the domain of the evaluation, and the distribution of the population in that domain [1]. Since in many situations it is not possible to gather complete knowledge regarding the domain, it is necessary to relax some of the restrictions involving the evaluation of FEV. In this paper we discuss solutions to this problem by using the concept of the Fuzzy Expected Interval (FEI).

Park, Ryu, and Lee recently defined a Henstock-type integral, which lies entirely between the McShane and the Henstock integrals. This paper presents two characterizing convergence conditions for this integral, and derives other known convergence theorems as corollaries.

This paper presents a fundamental theorem of calculus, an integration by parts formula and a version of equiintegrability convergence theorem for the M_α-integral using the M_α-strong Lusin condition. In the convergence theorem, to be able to relax the condition of being point-wise convergent everywhere to point-wise convergent almost everywhere, the uniform M_α-strong Lusin condition was imposed.

인류의 진보를 이끈 많은 수학자 중에는 장애를 극복하고 커다란 업적을 이룬 장애인 수학자들이 적지 않다. 그리고 이들의 수학자로서의 성공은 장애와 수학을 연결하는 좋은 모델이 될 수 있다. 따라서 본 논문에서는 국내 외에서 신체적 또는 정신적 장애를 극복하고 수학적 발전에 기여한 니콜라스 선더슨, 오일러, 루이스 캐롤, 솔로몬 레프셰츠, 루이스 앙투안, 가스통 줄리아, 레프 폰트랴긴, 아브라함 네메스, 존 내쉬, 버나드 모린, 아나톨리 뷔투쉬킨, 로렌스 바젯, 노베르토 살리나, 시어도어 카진스키, 리처드 보처즈, 디미트리 카네브스키, 황윤성, 엠마뉴엘 지록, 김인강, 재커리 배틀(한국이름: 이정남), 프라티쉬 다타 등과 같은 수학자들의 사례를 소개하고, 특수수학교육 환경에 대하여 논한다.

정압분자동역학 시뮬레이션에 의하여 주기경계조건을 지닌 L-J 입자들로 구성된 계의 액체-유리-결정 전이를 연구하였다. 원자체적과 엔탈피는 가열 및 냉각과정에서 온도의 함수로 계산되었다. 반경분포함수로부터 유도된 Wendt-Abraham비와 단거리규칙도를 나타내는 각도분포함수를 분석하여 액체, 유리 및 결정상태를 구분하였다. 초기 fcc 결정을 가열하여 얻은 액체상은 급냉시에 비정질화하나 서냉시엔 결정화하였다. 급냉으로 생긴 유리는 다시 서서히 가열하면 fcc로 결정화하였다. 자유표면을 지닌결정은 표면에서부터 용해가 시작되어 벌크에 비하여 낮은 온도에서 녹고 냉각시에는 빠른 냉각속도에서도 결정화가 쉽게 일어나는 경향을 보였다.

Chondrosarcoma of the chest wall is a rare primary neoplasm found to occur in elderly men. Patients present with an enlarging, painful, anterior chest wall mass arising from either the vicinity of the costochondral junction or the sternum. Treatment includes wide resection with appropriate chest wall reconstruction. We report an unusual presentation of this uncommon tumor occurring as a huge chest wall mass in a young teenage girl.

The purpose of this study was to analyze the delayed muscle soreness after exercise and the indicators of muscle damage. Subjects of this study were 9 male students. Some muscle enzymes and others(GOT, LDH, ALD, CPK in serum, WBC, ESR) that known as the indicators of muscle damage were measured before exercise. After measurements they run on a treadmill ($incline:25\%$, speed;3.5miles/h) for 7 min. on an average. The intensity of this kind of exercise was $90.5\%$ of maximal exercise intensity. After exercise, same indicators were measured at the just after exercise, 24hr after, 48hr after, 72hr after. Also muscle soreness level was evaluated at same intervals by make use of Modified Abraham's scale. The result was as follow: There was no relationships between muscle soreness and the indicators of muscle damage but ALD was the most important indicator that can be explains the muscle soreness very well.

The successful application of fuzzy reasoning models to fuzzy control systems depends on a number of parameters, such as fuzzy membership functions, that are usually decided upon subjectively. It is shown ill this paper that the performance of fuzzy control systems call be improved if the fuzzy reasoning model is supplemented by a genetic-based learning mechanism. The genetic algorithm enables us to generate all optimal set of parameters for the fuzzy reasoning model based either on their initial subjective selection or on a random selection. It is shown that if knowledge of the domain is available, it is exploited by the genetic algorithm leading to an even better performance of the fuzzy controller.
