We extend the ranges of the vacuum standards to 10^-6 Pa by injecting the gas flow into the lower vacuum chamber of the orifice flow type vacuum standards system. The systematic error of the vacuum measurement has been reduced by measuring temperature accurately by reducing leak rate of the flowmeter and by attaching the ballast tank to flowmeter. We measure N_2, He and Ar gases for the sensitivity of nude ionization gauge for the check of the vacuum accuracy. The results are compared with the result of other research institute.

It is important to interpret the soil chemical properties in order to effectively manage the farmland. This study was conducted to investigate the soil chemical properties of upland soybean field according to the soil series at 32 upland fields located in the parts of Gangwon-do. Soil sampling sites were selected by using the National Statistics DB and KSIS DB that is a soil environment information system provided by the Rural Development Administration. Soil samples were collected from 0~15 cm of top soil before seeding or transplanting, air-dried, passed through a 2 mm sieve, and analyzed for soil pH, EC, organic matter, available phosphorus (P2O5), exchangeable potassium, exchangeable calcium and exchangeable magnesium. The average chemical properties have exceeded the each nutrient optimum range level of RDA, except the organic matter in experimental soil 2015. And despite application of conventional fertilization, each soil series nutrient contents were change respectively. The results of this study suggest that conventional fertilization should be applied based on the analysis about the amount of accumulated nutrient contents in the soil.

이 연구는 유교, 특히 조선 성리학의 도덕교육에 의한 인격변화의 과정과 그 결과를 컴퓨터로 모의 실험하기 위하여, 조선 성리학자들이 이해했던 心의 구조와 그 작동의 모형을 작성해보고자 하는 데 그 궁극적인 목적이 있다. 아울러 그것을 통해서 조선 성리학의 큰 줄기를 형성한 퇴계의 심학과 율곡의 심학을 연구대상으로 포용하고, 그 둘 사이에 나타나는 차이점과 공통점을 살피고, 그 결과를 근거로 일종의 성리학 통합심성모델을 작성해보고자 할 때 필요한 이론적 정지작업을 하는 것이 본 연구의 실제 내용이다. 그 작업을 위하여 먼저 통합심성모델 작성의 이론적 관점과 기반으로서 일종의 구성주의의 관점을 채택한 이유를 밝히고, 그것에 의하여 성리학의 심성론의 해석과 그에 따른 심성모델의 구성 방식을 제시하였다. 아울러 서구의 심리철학에서 이해되는 mind, 인지과학에서 연구되고 있는 인간의 마음, 인공지능에서 이해되는 마음을 분석하고 그것과 구성주의에 의하여 재해석된 성리학자들의 마음과의 비교를 행하였다. 중요한 것은 성리학의 역사로 볼 때 똑같이 주자학 계열의 성리학자이면서도 인간의 심성의 관념에 관해서 대립적인 견해를 지녔던 퇴계와 율곡의 관점을 하나로 묶어서 통합심성모델을 작성하는 작업이다. 이에 대해서 본 연구는 퇴계와 율곡이 근본적으로 禮실천에 의하여 인간의 심성의 순수함과 정직함을 기르고 회복하려는 점에서 동일한 입장이라는 점에 착안하여, 사단과 칠정, 인심과 도심 등에 관한 理氣論적 해석에 차이가 있다고 하더라도 그것을 통합해 볼 수 있는 이론적 체제를 확보하고자 하였다. 현대에 논의되는 서구철학적 관점의 윤리학과는 다소 다른 방향과 관점에서 진행되는 이 논의는 인지과학과 비트겐슈타인류의 언어철학 등의 관점과 상호 통하는 면이 있으며, 현대 서구철학의 윤리학이 해결하지 못하는 인간의 도덕적 앎과 행위와의 괴리를 넘어설 수 있는 이론적 가능성을 보여준다고 전망된다. 그 점을 인지과학자인 프란시스코 바레라, 언어철학자인 허버트 핑가레트 등의 이론을 근거로 추론하였다. 결론적으로 퇴계와 율곡의 성리학 심성모델은 현대 윤리교육에 대해서 인간의 심신관계 및 실천지향의 윤리교육의 기초를 제시할 수 있으며, 나아가서 그에 관한 실용성도 풍부하게 지니는 것으로 생각된다. This study has a purpose to make a structure of mind and its working principles, which had been thought and understood by confucians of Chosun Dynasty, for computer simulating processes of peronalyity changes through Chosun Dynasty's moral education. This study includes Simhak(心學) of famous Chosun confucians, Toegye and Yulgok, and compares commons and differences of two scholar's theory. The key of this study prepares a necessary theoretical foundation for making a Neo-confucian integrated mind model from such results. We explained why we adopt radical constructivism as a theoretical framework for the integrated mind model, and proposed an interpretation of Neo-confucian mind theory and a method of constructing mind model. Futhermore, we look around a mind of western psychological philosophy, a mind of cognitive science, and a mind of artificial intelligence, and we have compared the confucian mind which is re-interpreted as radical constructivism with such minds. An important work is to make an integrated mind model of Toegye and Yulgok because two scholars are same Neo-confucian, but assisted own theories about human mind. Although the interpretations of Sadan(四端) and Chiljung(七情), Insim(人心) and Dosim(道心) are different each other, encouraging and recovering purity and honesty human mind with the practice of rituals is very much alike. Therefore we want to prepare theoretical foundation for integrating both. This argument is different from ethics of modern western philosophy, but have something to do with cognitive science and Wittgenstein-like philosophy of language. We expect that this idea show a theoretical possibility beyond the dissociation between ethical thinking and behavior, which modern western ethics can't solve. Such a conclusion is inferred from the concepts of Francisco Valera, the cognitive scientist, and Herbert Figarette, the linguistic philosoper. Now to conclude, the confucian mind model of Toegye and Yulgok can provide the explainable mind-body relationship and the foundation of practical moral education for modern education. We believe that the model has much possibility for practical use.

Normal feet have the longitudinal arch for the distribution of the weight. The longitudinal arch is known lateral and medial longitudinal arch. Collapsed arch of the foot is flat foot and it is the cause of the foot pain. Of course the low arch does not always make a foot problem in sports and daily activity. Longitudial foot arch is visible in the standing foot lateral radiograph, Harris mat and visual observation. In Radiographic study the lateral Talo-lst Metatarsal angle is known in standing foot lateral film. But the longitadinal medial arch is not correctly obtained in Talo-lst Metatarsal angle. So this study for Calcaneo-lst metatarsal angle in standing lateral foot radiograph is more valuable angle in medial longitadinl arch. And we do the study on difference in the longitadinal arch in normal weight versus overweight person.

대부분의 나라에서 물류비 가운데 수송비의 비중은 적어도 50%이상을 차지하고 있으며, 수송비의 절감 없이 물류비를 줄이는 것은 상당히 어려운 실정이다. 이러한 수송비 부담을 줄이기 위한 공동수송 방안이 일부 시행되었으나 정보의 누설, 기업의 영세성, 중앙물류센터 건립을 위한 과다한 초기 투자비용, 시스템의 유기적인 체계의 결여로 인해 실효를 거두지 못하고 있다. 이에 대한 대안으로 공동수송이 비교적 용이한 산업단지 소재 중소기업들간의 소량 다빈도 납품을 위한 공동수송이 최근 추진되고 있다. 본 논문에서는 이러한 산업단지 공동수송에서 화주기업들의 화물 발송일자가 익일이 아닌 여유일이 있는 경우 최적 배차계획을 통하여 수송비가 추가적으로 절감될 수 있는 폭을 추정하기 위한 컴퓨터 시뮬레이션 모델과 그 분석결과를 소개한다.

Back ground : It is important to evaluate the patient presenting with non-traumatic chest pain in emergency department, and it is also difficult to classify appropriately. The purpose of this study is to predict probability of acute myocardial infarction(AMI) and assess the group for low probability of AMI that is target for observation-unit of chest pain in emergency department. Methods : A prospective, clinical study was performed from March 1998 to August 1998 at the department of emergency medicine, Ewha Womans University Mokdong hospital. We classified high-probability group and low-probability group of AMI according to Goldman's algorithm and then compared with the final diagnosis. Results : The study included 218 patients. 84 patients(39%) was the high-probability group and 134 patients(61%) was the low-probability group of AMI. As compared with final diagnosis, AMI was 47 patients(56%) among the high-probability group and 1 patient(0.7%) among the low-probability group. We observed sensitivity of 98%, specificity of 78% in predicting AMI. Conclusion : The classification according to Goldman's algorithm may be useful predictor of AMI and improve triage for emergency department patients with chest pain. It is also helpful for management of observation-unit of chest pain in emergency department.

Feeling the keen necessity while the authors were studying on the family attitude toward epilepsy the study of the social attitude toward epilepsy was conducted. A total sample of 1,400 adults were drawn from the available population who reside in the five major areas and its outskirts. The sample contained proper proportion by sex, by age, by occupation and by educational level. A series of questions framed to detect a concept of the present day social attitude toward and knowledge of epilepsy were asked by the method of questionnaire. From the obtained results the authors have observed that knowledge of epilepsy was widespread and negative, guarding and rejecting feelings were fairly pronounced. 1) Knowledge of epilepsy was found in 94.28% of the samplings, through either having seen a seizure(53.57%) or having heard about it(40.71%). 2) When they were asked about their feeling toward epilepsy, bad feeling was expressed by 75%, unpleasant feeling by 69.21%, having epileptics around their house and 62.21% wanted to have epileptics isolated. 3) When asked if they would let their children play with epileptics, 58.57% answered No and only 17.14% said Yes. 4) Employment was objected to by 28.50% and advocated with qualification by 48.93%. 5) Marriage was approved only by 11.79% and objected to by 56.14%. But when asked if it were their own children case, 74.14% objected and only 3.29% approved. 6) Sympathetic feeling toward the family of epileptics was expressed by 72.29% and benevolent feeling by 15.64%. 7) Among those diseases including epilepsy which are generally feared by public, such as cancer, schizophrenia, poliomyelitis, syphilis, encephalitis and tuberculosis, epilepsy was feared in order next to cancer and schizophrenia. It is the author's feeling gained from the results that the public enlightenment and better understanding of epilepsy are urgently required in this society.
