승용차-보행자간 충돌위치에 따른 보행자 전도거리 분포형태

권선민 목원대학교 산업정보언론대학원 2017 국내석사

이 논문에서는 승용차와 보행자간의 충돌위치에 따른 보행자의 전도거리 분포형태를 MADYMO 시뮬레이션 기법을 사용하여 분석하였다. 기존 연구에서는 주로 차량의 범퍼중심과 보행자가 충돌되는 경우에 대해서만 분석을 하였다. 그러나 본 논문에서는 범퍼전체의 길이에 대하여 충돌위치를 2.5cm간격으로 설정하여 분석하였다. 보행자의 충돌위치를 차량 중앙에서부터 바깥쪽으로 이동할수록 전도거리는 조금씩 감소하였다. 그러나 충돌지점을 차량중심으로부터 바깥 쪽으로 이동할 때, 특정 지점부터는 전도거리가 급격히 감소했다. 이러한 전도거리가 급격히 감소되는 임계점을 발견했다. 임계점의 위치는 차량 형상과는 관계없이, 보행자의 어깨가 차량과 접촉되지 않는 위치에서 부터 시작했다. 임계점보다 안쪽 구간에서 충돌할 경우, 전도 형태는 기존의 연구 결과와 유사하였다. 임계점 바깥 구간에서 충돌할 경우, 전도거리는 차량의 형태가 유선형에 가까울수록 더욱 크게 감소하는 것으로 나타났다. This thesis investigates pedestrian-thrown distance patterns by vehicle-pedestrian collision points using MADYMO simulation methode. Existing researches mainly dealt with the collisions between center of bumper and pedestrian. But this thesis analyzes the collisions between vehicle-pedestrian on the whole length of bumper. As a result, if the collision point are far from the center of bumper, the thrown-distance decrease. At some collision point, the thrown distance decrease rapidly. This critical point locate where pedestrian’s shoulder do not contact the vehicle in spite of various shapes of vehicle. The thrown patterns are similar to those of existing researches where collision points locate between center of bumper and critical point. But where collision point locates out side of critical points, thrown distance of vehicle designed aero-dynamic style decreases more rapidly than that of normally designed vehicles.

We are living in three millennium. This is the important time that we can reflect on past 20th century and make the first step to the next century, so we should love the poor and proclaim Heaven and the Gospel to them to make it the true church that Jesus wants to be. Then who is the poor to us and how can we evangelize them newly method? In the chapter 1, I study the concept of 'New Evangelization' in the problem of new evangelization for the poor. Pope John Paul II referred 'New Evangelization' first and it means the whole activities which are greatly contributed to evangelization with the new enthusiasm, new method, and new expression for realization mature church community, as it has been appeared in his several encyclicals. 'New Evangelization' is related to the signs of the times that new period requires and it urge us to consider on the presence of the God and true sign of His plan. By the way, the important sign of the times today is new evangelization for the poor. In the chapter 2, I examined the Bible and the church document to understand about the poor. First, I looked over the poor in the Old Testament and New Testament. In the Old Testament, the poor mean that the people whose property was forfeited and who are of low social standing with being given an unfair treatment and this also means mental and spiritual condition. In the New Testament, the poor is understood as in not only material but also spiritual meaning, and that is more concrete and practical than in the Old Testament. The poverty of Christ is an act of salvation and love, therefore this act is work of sharing with the poor and being poor. The first thing in the church documents, Documents of the Second Vatican Council says that our church must be church of the poor. At the same time, the mission points to the evangelization for the poor. From encyclical of Pope Leo 13' Rerun Novarum to recently announce Tertio Millennia Adveniente, the message of the social encyclical doctrine related to 'Prior choice of the poor"(announced by Pope Leo 13') says about an effort about overcoming the material poverty in this social political circumstances and maintaining the freedom and dignity of man. Specially, Tertio Millennio Adveniente by Pope John II , says that the church must be concerned about the poor and alienated today. In the chapter 3, I study the church renewal and Solidarity which is contributed to New evangelization for the poor. In the Tertio Millennia Adveniente, Pope John Paul II, urges us repent based on the purport of 'The Second Vatican Council'; church purification and renewal. Solidarity is the core value of Christianity about society and it contradicts the plan of God who wants union of people and fraternal love in a community and circumstances. Korean church make an effort to unite between God and nation, nation and nation through the company life with the poor after the spiritual of The early Christian church. In the chapter 4, I study the evangelization of culture, that is the problem of Incultration and social welfare, it is an effort of New evangelization for the poor. Church must establish righteous humanity based on the teachings of Christ in the culture and must be concerned to "The prior choice of the church about the poor" which is the sign of the times and the core subject of social doctrine. Korean church must accomplish the evangelization of the culture based on this sprit in our world. For this purpose, we must use and apply several teachings from The memorial 200th Pastoral a bill of Korean church which is in progressing inadequately but we try evangelizing the poor and the' alienate over all other people. Korean church was concerned to the welfare of the believe and neighbour in the beginning. But today, many changes in the our society and catholic social welfare activity is placed in a turning point. So we should ' diagnose our church that cope in a positive light with the problems that will be occurred and have ministerial prospect. Therefore, we should study and develop social welfare 'activity in catholic church to being welfare ministry so the poor, church, and society can be union. More over, we should make it to important foundation for new evangelization for the poor. The church must choose the poor, the alienated in the center of the society over all other people and evangelize them by the love of Christ. We will do our best to make the beautiful world of God in which love and peace is overflowing and all the people can live equally by God's will.

웹서비스를 이용한 개방형 NMS플랫폼에 대한 연구

권선민 忠南大學校 大學院 2009 국내석사

NMS is the system designed for a network management. Network management of past has been applied to small management.but in the recent times, number of the equipment and manage scope to manage was plentifully magnified. Also, in the past We just monitored about equipments but in recent times We need monitoring in service. So I suggest new monitoring techniques. Existing SNMP monitoring techniques use polling techniques but new monitoring is Data Push techniques. It minimizes network delay time response patterns from request, export and response patterns of existing Polling technique, export and response patterns and minimizes a network delay time with response data push. Therefore, without system increase it makes more equipments accommodate. And use of web service techniques is not the simple String data but is structurized complexed data transmit. From this It accommodates various monitoring scope with service monitoring and It will be able to manage the network more in detail.

PET bottle flake의 physical recycle 용융방사에서 Diisocyanate의 첨가가 물리적 성질에 미치는 영향

권선민 영남대학교 대학원 2024 국내석사

Abstract As PET pollution accelerates, various studies are being conducted to recycle it. PET recycling is divided into physical recycling and chemical recycling. During physical recycling, the viscosity or molecular weight decreases due to thermal decomposition, thereby deteriorating the physical properties. To overcome this, research is being conducted on increasing viscosity and molecular weight by chain extension by adding an additive called a chain extender. In this study, experiments and analyzes were conducted on the chain extension effect using 4.4'-Methylene diphenyl diisocyanate. proceeded. DSC and TGA analysis were conducted on the thermal properties of rPET powder manufactured according to the MDI content and specimens manufactured by melt spinning to confirm the melting point and thermal decomposition temperature according to the MDI content, and the changes in intrinsic viscosity and viscosity accordingly. Confirmed. MDI content was analyzed through intrinsic viscosity analysis and rheometer analysis. Molecular weight was calculated according to intrinsic viscosity. The crystallinity index was calculated based on the density of the produced rPET fiber. Scanning electron microscopy (SEM) analysis was performed to analyze the surface, and UTM (Universal Testing Machine) analysis was performed to analyze tensile strength and elongation at break, confirming that tensile strength and elongation increase depending on the MDI contents.
