In review of he current technical difficulties and weaknesses in producing filters, this investigation presents a method to evaluate metallic fiber filters by utilizing the theory of fluid dynamics. A method for evaluations of the efficiency of filters in estabilished. Also the filter configuration is analyzed and the filter media is characterized. A trial product of pleated type filter is designd and produced. The product has optimal filtering surface area per unit flow rate. Also tests for filtration efficiency and characterizations of the products were conducted.

This year is 100th since Marx died. There have been so many reports that the 100th anniversary of Marx's death was being marked in unforgettable ways. If Marx were to come back, what does he discover? Maybe he discovers that things aren't what he has expected. What is the significance of polish crisis in early 1980s? It has taught the world a lesson that is both stark and undeniable: as a means of organizing an economy and providing for the well-being of a citizenry, Communism is a failure. It is related to the dark future of communism. The causes of polish crisis are two: one is the fall of social status and the consciousness of frustration. The other is the continuous failure of Economic policy and the bankrupty of national Economic life. If we interpretate the two causes on the thread of connection in communist system, the former implies the "equality" idea of communism is falseconsciousness. The latter means the practical limit of communist economic system. Nowaday in Communist Societies, the dream of classless society is not practical. Rather as Millovan Djilas said, new class came in view. He sees the party as the incumbent institution of class rule: The new ownership is not the same as the political government, but is created and aided by that government. The use, enjoyment, and distribution of property is the privilege of the party and the party's top men. We call them Nomenklatura. The alienation of the worker from his work is at least as great today at the plants in communist countries as it was in the Manchester textile mills that Engels studied in the mid-l9th century. The command economy, too is slowing down if not breaking down. No communist country has met the proclaimed goals of its Five-Year plan: The desired results that the economies were organized to achieve have simply failed to materialize. And the projections for the next ten years are even gloomier. So U.S.S.R and Eastern Europe try to reform the economic policy, But those reforms challenge the very essence of the system, which is totalitarianism. It is the dilemma of the communist countries hold. What is the result of Soviet Communist System? The result is a tension and a paradox. On the one hand, inefficiency, stagnation and alienation are theinevitable accompaniments of the centralization, elitism and repression that are necessary to carry out the first order of businss: the preservation of power. On the other hand, the political system is well designed to be impervious to the consequences of the economic failure and social demoralization that are built into it.

최근 많은 과학적 현상에서 서로 다른 위치에 있는 자료들이 공간적인 상호 작용에 의해 영향을 받는 복잡한 컴퓨터 모델링이 연구되고 있다. 그러한 연구들은 주로 공간적 변인에 의해 영향을 받는 자료에 대하여 상호 연관성을 고려한 함수식에 대한 예측모형에 초점을 두고 있다. 본 연구에서는 컴퓨터 실험에서의 메타모델로서 크리깅 방법을 제시하고, 컴퓨터 모델링을 통하여 생성된 자료를 가지고 크리깅 방법의 정확성과 효율성을 검증하였다. In many fields of design of experiments, the complicate computer modeling, which is influenced by inter-action of various data, has been studied. These studies are focused on prediction models for the functions considering the inter-correlated points influenced by spatial variation. In this paper, we describe the definition, the prediction function and the algorithm of kriging method and examine the accuracy of kriging by using validation method.

In this paper, We discuss an algorithm for the recognition of partially visible two-dimensional object in a gray scale image. Our algorithm uses the local shape of contour segments near critical points as the fundamental feature vectors and the database is implemented using an k-d tree structure. Experimental results showing our algorithm's performance are presented.

본 연구에서는 부모의 양육지식과 가정내 부정적 생활사건에 따른 부모와 자녀 변인의 차이 를 분석하였다. 연구대상은 11∼18개월의 영아 1,904명과 그의 부모이다. 사용된 자료는 육아정책연구소의 한국아동패널(2009) 2차년도 데이터로 기술통계, 다중응답분석, t-검증 으로 결과를 분석하였다. 연구결과 양육지식이 양호한 집단은 월가구소득, 부모됨의 태도(정서적), 자기효능감, 자아 존중감, 자녀의 활동적 기질, 의사소통능력이 높았으며, 양육지식이 적은 집단은 부모됨의 태도(도구적), 우울, 양육스트레스에서 각각 높은 점수를 나타내고 있었다. 가정내 부정적 생활사건이 덜한 집단은 월가구소득, 결혼만족도, 남편의 양육참여, 자기효능감, 자아존중감, 자녀의 정서적 기질에서, 가정내 부정적 생활사건이 많은 집단은 부부갈등, 우울, 양육스트 레스에서 높은 점수를 나타내고 있었다. This study aimed to examine the analyze the differences of children’s and parents’ variables between lowest and highest groups of parenting knowledge and negative life events within family. The data were from 1,904 children aged 11 to 18 months and their parents, participated in the 2nd Panel Study on Korean Children in 2009 by Korea Institute of Child Care and Education. The descriptive statistical analysis, multiple-response frequency analysis, and t-test were used. The results showed that the highest group in parenting knowledge, also showed higher scores in monthly income, emotional parenting attitude, self-efficacy, self-esteem, child’s active temperament, and communication skills. The lowest group in parenting knowledge, showed higher scores in instrumental parenting attitude, and parenting stress. The group with least negative life events within family showed higher scores in monthly income, marriage satisfaction, husband’s parenting participation, self-efficacy, self-esteem, and child’s emotional temperament. The group with highest negative life events within family showed higher scores in couple conflicts, depression, and parenting stress.

Operation of a current source inverter is significantly affected by its operating frequency and directing current. At normal operating condition its output current can be assumed, but at high frequency its operation become unstable. In this paper, a model for single phase current source inverter is developed and analysed by digital computer simulation. And that result can be applyed to all operating condition.

In this paper we design a resource sharing system which is an loosely coupled heterogeneous multicomputer system with radial bus configuration. It consists of one host processor and more than two terminal processors. The host processor allows the sharing of hardware resourceses, software and data bases among the terminal processors. This system is implemented with Cromenco microcomputer system.

합병증이 동반된 Meckel씨 게실을 가진 환자의 치료에 대한 필요성은 과정이 문제이다. 하지만 우연히 만나는 게실의 처치는 논란 중이다. 부수적인 게실 절제술(incidental diverticulectomy)의 제안자는 증상이 있는 게실의 외과적 처치는 중요한 이환 및 사망률은 지적한다. 이를 반대하는 사람들은 전 생애를 통해 합병증의 위험성이 낮게 나타나므로 필요가 없다고한다. 게실의 예방적 제거는 개복술시 우연히 발견 될 때 시행한다. 이는 남아있는 게실이 나중에 합병증을 일으키는 것보다 술후 합병증의 위험성이 매우 적음을 알 수 있다. 저자들은 합병증이 동반된 Meckel씨 게실 2예를 경험하였기에 문헌 고찰과 더불어 보고하는 바이다. The necessity for therapy with complicated Meckel's diverticular is a matter of course.However, management of the incidentally encountered diverticulum is controversial. Proponents of incidental diverticulectomy point to the significant morbidity and mortality rates of surgical treatment of symptomatic divenicular. Other authors base their opposition to incidental diveniculectomy on the low risk of complications developing during lifetime. Prophyillctic removal of the diveniculum is indicated when it is found incidentally at laparotomy, because there are few postoperative complications and the risk exists that the remaining diverticulum may be the cause of later complication. The 2 cases of complicated Meckel's diverticulum are reported with a brief review of literature.
