It is obvious that adequate nutrition is essential for growth and development of school children, and many elementary schools in this country have already practiced it. Therefore, it would seem apparent that the school feeding program would have a significant effect on the growth and development of school children. This paper presents a two-year experimental school-feeding program from 1973 to 1974, and attempts to evaluate its effects by before-and-after nutrition surveys conducted in two elementary schools, one experimental and the other as a control. The two schools are both located in the same county (Yongin-Kun, Kyunggi-Do), and the families of their students are presumed to share the same socio-economic level. To assess the effect of school-feeding, we measured height, weight, chest circumference and grasping power. Physical examination was done foresigns of nutritional deficiency. A stool examination for parasites and blood examinations for hemoglobin, hematocrit and serum protein were included. Analyses were done for 150 students selected randomly at the beginning of the program. These students attended the school throughout the program period. Results are as follows: 1. The amount of increase of height, weight, chest cirumference and grasping power were greater in the experimental school than in the control school, but the differences are not statistically significant. 2. Signs of vitamin deficiency decreased in both experimental and control schools during the two-year program period. 3. At the time of the 1974 post-survey, values of Hb. & Hct. revealed no significant differences between the two schools, but serum protein level was a little higher than that of general Korean rural children of the same age. 4. Infestation rate of parasites had increased in both schools during the two-year program period. 5. Each student of the two schools was classified into three major classes, according to the level of economic condition of his or her parents, namely higher, middle and lower. The results of each class of the experimental school was compared with that of the corresponding class of the control school, expecting the relative magnitude of change largest in the lower economic class of the experimental school. However, change was greatest in the middle class, still not being statistically significant. Finally, the authors concluded that the two-year period for such a program is not sufficiently long for its beneficial effects to be demonstrated and measured. As long as the growth and development of children are concerned, planning with a more distant perspective is required, as well as the development of new methods of evaluation.

Obtaining an available information on health concerns of parents of school-age children and furthermore developing the sound policy for the public on health education, this study was conducted during Nov.-Dec. 1985 in the four selected areas; Seoul, large, middle and small city, and farming and fishery villages for 3,337 parents of schoolchildren in Korea. In this study, parents complected a questionnaire containing 34 items related to health concerns(e.g. drinking alcohol, air pollution, cancer, etc. see Table 4 and Fig. 2). For each health items, respondents were asked to indicate a choice between three levels of concern; 'Very high concern,' 'Moderate concern,' 'Little concern', and 'No opinion'. An analysis of responses indicated that most of the top ten health concerns identified by parents as cancer, abortions among high school students, medical malpractice, water pollution, traffic accidents, air pollution, suicide of parents and homicide of offspring, heart disease, venereal diseases, and high blood pressure in that order. Those health problems about which respondents were least concerned were more closely related to the individual, such as drinking alcohol, smoking, tooth decay, gum disease, underweight, overweight. Of greater concern were more such as water pollution, abortions among high school students, air pollution, accidents, medical malpractice. For cancer, heart disease, high blood pressure, various accidents, environmental pollution, parents showed high concern, however, for health issues which contributed as causative influences such as lung cancer from smoking and liver cirrhosis and traffic accidents from drinking alcohol showed less concern. Relationship between parent's residential areas, educational level and sex distribution and health concern showed little difference, however, for these issues parents identified as relatively high concern. Most parents stowed more concern in sex-related of family-related health issues such as abortions among high school students, suicide of parents and homicide of offspring.

N/A Particle-reinforced metal matrix composites via the Osprey spray casting process were fabricated by injecting second phase particles of Al₂O₃(<40㎛) and W(6㎛) into the spray of Cu droplets, and the thermal behaviors of the composite droplets during flight were considered theoretically on the basis of mixing modes between the Cu droplets and the reinforced particulates injected. It was found that the W-injected spray is comprised of particle-embedded droplets, and the Al₂O₃-injected spray comprises particle-attached droplets. From the predicted results of the thermal behaviors of the composite droplets and preforms produced, it is concluded that the thermal behaviors of the composite droplets during flight, and during the subsequent deposition are strongly influenced by its mixing modes between the reinforced particulates and Cu droplets during flight.

전자무역 기술 관련 동향의 흐름은 기능적이고 계층적 측면으로 서비스와 어플리케이션, 네트워크계층으로 발전해 가고 있는데, 대부분의 계층적 분야가 전자무역 확산이 본격화되기 이전에 정립되다 보니 기존의 체계는 국제교역 관점의 기술을 포괄하는데 한계가 있게 되었다. 따라서 이 같은 한계를 극복하기 위해 새로운 기술 동향의 정책 정립이 필요하게 되었다. 본 논문에서는 기술 분야의 기업간 통합을 포함하여 내부적 네트워크 및 이에 따른 문제점과 개선방안을 제시하였다. 또한, 전자무역이 새로운 기술 환경에서 제공하는 가능성과 이것이 기업들에 미치는 효과를 제시하였다. The trend of the electronic trade related with technology has been developed into the steps of service, application networks in its technical skill and scopes. But most fields for the steps were established before the electronic proliferation of the electronic trade and so the existing systems have had a limit in including the viewpoints for the international trade. Accordingly, to cover the limit, the policies for the new technical trend are necessary. In this article, the international networks, problems and improvement plans including the integration between companies in the technical sides are presented. And further the possibility and effects on the companies which are given by the electronic trade in the new technical circumstance are also presented.

N/A Microstructural characteristics of Al-3.63wt.% Pb hyper-monotectic alloy rapidly-solidified by melt spinning were examined. Possibility of forming a planar liquid-solid interface during rapid solidification of this alloy was also considered with a morphological stability theory, and a mechanism of forming banded structure observed at the bottom parts of melt-spinned specimens was considered as well. Application of the absolute stability criterion predicts the liquid-solid interface of the primary aluminium phase to be able to maintain a planar interface during the early stage of rapid solidification. Formation of banded structure was supposed to be resulted from the release of latent heat during solidification, which affect the stability of a planar liquid-solid interface.

네트워크와 컴퓨터 기술의 발달로 물리적으로 분산된 컴퓨터를 하나의 자원으로 사용하려는 연구가 많이 진행되고 있다. 일반적으로 이러한 연구들은 메시지 패싱을 기반으로 하는 환경을 개발하는 것이 주류를 이루고 있다. 이러한 환경은 보통 과학계산용 문제를 풀기 위해 많이 사용되고 주어진 문제의 내부병렬성을 이용하여 병렬처리 하게 된다. 따라서 보통 이러한 환경에서는 고도의 병렬성을 얻을 수 있다는 장점이 있는 반면에, 프로그래밍이 어렵고, 사용하기가 어려우며, 분산된 컴퓨터에 사용자의 계정이 있어야 한다는 단점이 있다. 그런데 만일 주어진 문제가 완전히 독립적인 작은 문제를 분할된다면 더욱 효율적인 환경을 만들 수 있다. 이러한 문제 유형은 생물정보학, 3차원 애니메이션, 그래픽스 등에 많이 준재하며, 이를 위한 새로운 환경 개발은 매우 중요한 연구라 할 수 있다. 따라서 본 논문에서는 이러한 문제를 효율적으로 처리하는 프록시 컴퓨팅 기반의 InterCom이라는 새로운 환경을 제안하고, 이들 구현한 것에 대해서 설명한다. 이 환경은 에이전트, 서버, 클라이언트로 구성되어 있다. 이 환경의 장점은 프로그래밍하기가 쉽고 분산된 모든 컴퓨터에 사용자 계정이 없어도 되며, 분산되는 코드를 자동 컴파일해 줌으로써 사용하기 쉽다는 것이다. Development of network and computer technology results in many studies to use physically distributed computers as a single resource. Generally, these studies have focused on developing environments based on message passing. These environments are mainly used to solve problems for scientific computation and process in parallel suing inside parallelism of the given problems. Therefore, these environments provide high parallelism generally, while it is difficult to program and use as well as it is required to have user accounts in the distributed computers. If a given problem is divided into completely independent subproblems, more efficient environment can be provided. We can find these problems in bio-informatics, 3D animatin, graphics, and etc., so the development of new environment for these problems can be considered to be very important. Therefore, we suggest new environment called InterCom based on a proxy computing, which can solve these problems efficiently, and explain the implementation of this environment. This environment consists of agent, server, and client. Merits of this environment are easy programing, no need of user accounts in the distributed computers, and easiness by compiling distributed code automatically.

성능감시기는 분산처리 환경에서 프로그램의 성능을 추적하고 평가하기 위해 필수적인 것이다. 성능감시기는 출력방법에 따라 오프라인과 온라인으로 나눌 수 있다. 오프라인성능감시기는 프로그램이 종료된 후에 그 성능을 분석하는 것이고, 온라인 성능감시기는 프로그램의 수행 중에 분석하는 것이다. 따라서 프로그램의 빠른 분석과 디버깅을 위해서는 온라인 기능이 필수적이다. JaNeC은 Java로 구현된 분산처리 환경으로 이를 위한 오프라인성능감시기가 포함되어 있다. 그러나 이 성능감시기로는 JaNeC에서 수행되는 프로그램을 효율적으로 분석할 수 없다. 따라서, 본 논문에서는 JaNeCe에서 수행되는 프로그램의 빠른 분석과 디버깅을 위해 온라인 성능감시기를 설계하고 구현하는 것에 대해서 설명한다. 이 온라인 성능감시기는 분석하고자 하는 프로그램에 영향을 최소화하도록 설계되었으며, 효율적인 프로그램 분석을 위해 다양한 형태의 그래픽 출력을 제공한다. 또한 프로그램이 종료된 이후에도 다시 분석할 수 있도록 하기 위해 오프라인 성능감시기와의 인터페이스도 제공한다. A performance monitor is indispensable to trace and evaluate performance of a program under distributed processing environment. A performance monitor il classified as off-line and on-line according to its output method. An off-line performance monitor analyzes its performance after a program terminates, and an on-line performance monitor analyzes its one while a program runs. Therefore, the on-line function is essential to analyzing and debugging the program fast. JaNeC, distributed processing environment that is implemented in Java, contains an off-line performance monitor for this. However, this performance monitor may not analyze the program running on JaNeC efficiently. Consequently, this paper explains that an on-line performance monitor is designed and implemented for fast analysis and debugging of the program running on JaNeC. This on-line performance monitor is designed to minimize effects on a program to analyze, and provides various forms of graphic output, to analyze the program effectively. In addition, even after a program terminates, it provides interface with the off-line performance monitor, to analyze again.
