Recently, the demand for reliability verification is increasing while designing and manufacturing molds using injection molding computer aided engineering(CAE). When performing flow analysis verification, a spiral mold is produced and compared with CAE. Because of the spiral shape, we needed a comparative evaluation with the flow distance of products with different forms. So, we compared the weight and flowed length using CAE. Variables are the change in the width of the spiral shape and the shape of the bar and plate. When the width of the spiral shape is 23mm rather than 15mm, the flow distance flows 30∼70mm more, with a maximum difference of 13%. As a result of comparing the spiral shape and the long square shape with the same width, the spiral shape had a flow distance of 60 to 105mm further, and a difference of up to 28% was found. As a result of comparing the plate shape and the spiral shape with a 15mm width product, the spiral shape has a flow distance of 310∼380mm further, and a difference of up to 82% is different.

공유 트리 기반 멀티캐스트 라우팅을 위한 코어 선택 방법

코어 기반 트리(CBT:Core Based Tree) 멀티캐스트 라우팅은 인터넷을 위한 멀티캐스트 라우팅 프로토콜이다. CBT는 멀티캐스트 연결을 위해 하나의 공유 트리를 구성하고, 이 공유 트리는 코어라는 센터 노드를 루트로 한다. 코어 기반 트리 멀티캐스트 라우팅에서 코어의 위치 선정은 비용과 성능 측면에 많은 영향을 끼치고, 코어의 배치 방법은 네트워크 토폴로지에 따라 달라진다. 본 논문에서는 간단하고 효율적인 코어 선택 방법을 제안하고자 한다. 제안한 방법은 거리 벡터 정보를 필요로 하며, 추가적으로 표본 상관 계수 결과를 이용하여, 멀티캐스트 그룹에 속해있는 멤버들의 배치상태에 따라 적합한 라우팅 알고리즘으로 최소평균비용을 갖는 노드를 코어로 선정하는 방법, 또는 PIM-SM 방법을 선택하는 것이다. 제안한 방법의 성능은 평균지연, 최대 지연, 총 비용과 같은 세부적인 실험을 통해 기존연구와 비교하였으며, 실험 결과 제안한 코어 선택 방법이 매우 효율적임을 알 수 있었다. The Core Base Tree (CBT) multicast routing architecture is a multicast routing protocol for the internet. The CBT establishes a single shared tree for a multicast connection. The shared tree Is rooted at a center node called core. The location of the core may affect the cost and performance of the CBT. The core placement method requires the knowledge of the network topology In this Paper, we propose a simple and effective method for selecting the core. This method requires the distance vector information. in addition, we used results that calculated sample correlation coefficient. And then we select suitable routing algorithm according to member's arrangement states in muliticast group. we select core node that have minimum average cost or PIM-SM protocol is selected. The performance of this method is compared with several other methods by extensive simulations (i.e mean delay, maximum delay, and total cost). Our results shows that this method for Selecting Core is very effective.

This thesis critically analyzes the present condition of Christianity in Asia. It notes the shift of World mission from a Western perspective to Asian perspective. It also provides a descriptive analysis of the factors affecting the spread of Christianity in Asia. Concrete recommendations are drawn to fortify Asian missions. Furthermore, this thesis discusses the role of Korean Christians, as a majority, in the spread of the gospel. The Christian population in Asia is considered statistically as a marginalized denomination with less than ten percent (10%) share of the total world Christian population. However, considering the thirty percent (30%) Christians around the world, Asian Christians constitute a minute proportion to Ule face of the Christian faith. This is taken in the context of a global perspective that Christian Mission in Asiastill continues to be in the state of passivity despite the numbers of missions sent abroad to spread the gospel. The 21st century World Mission has shifted its target to the Asian third world countries. W. B?lman stressed that the center of mission is moving towards the 3rd world countries. Missions have taken into account the number of population and the di stinctive features of Asia. W. B?lman also noted that before the 21st century the Christian population among the whites is more overwhelming than the nonwhite Christians. In the turn of the 21st century, the growth has changed. This is manifested in the growth of non-white Chri stian population in Asia after the evangeli zation by the western missionaries. To date, the 3rd world Christians has taken quantum leaps to share the gospel to their neighboring countries. Despite the missions conducted by churches and Christians in Asia, the people has stayed steadfast to passivity to the acceptance of the gospel. One distinct feature of Asian roots is its various cultural heritage. These roots have been celebrated and preserved to take its truest color. The spirit evolved by this heritage enlivens the Asians. Throughout the years missions have approached these cultures in the light of western ideology and theology. The differences created a conflict and resulted to the passivity of Asians to Christian faith. The author agrees with Aloysius Pieris that poverty is a major factor in the resistance of the Asians to accept the gospel. The control of st ru ctured institutions, s uch as government, eco nomy and education, have hindered the influx of new fa ith. Aloysius Pieris calls this forced poverty. Asian countries have been the crad les of world religions. The growth of these religions all ied the growth of civilization, which strengthened believers in Asia. Some of these world religions are: Shintoism, Confucianism, Buddhism, Taoism, Islam and even Christianity. These religions have guided believers through their respective scriptures and the tides of civilization strengthened these faiths among Asians. Missions have been idealistic to penetrate the threshold of these major religions and make them accept the Christian faith. But the plurality of religions curtailed the light of Christian faith to the Asians. The Asian population plays a vital challenge to the world Christian Mission. It constitutes a big portion of the world population in which the Christian faith has not reached. The immersion of missionaries to do the task of sharing the gospel has been in vain. Passivity of Christians has always been the reason for the resistance. However, this research, P9sits that mission should be revolutionized to achieve its goal of sharing the gospel. Choan Seng Song suggests Transpositional Theology to carry out the mission. This is the change of approach to introduce the gospel based on Asian perspective. Aloysius Pieris calls this as Asian style gospel. Adaptation to the different cultures in Asia through mission research will play crucial role in the attainment of the task. With the adequate knowledge of the culture, genuine empathy to the experiences, situation, condition and status of Asians will ease the immersion of missionaries in a different culture. The establishment of oneness to the particular group of Asian will be timely for the inculcation of the Christian scripture. Thus, increasing the chance to spread the gospel successfully. Since oneness is very important to the spread of the gospel, Asians are more capable of understanding, adapting, empathizing with fellow Hinduism, Asians. This is called by Choan Seng Song as the 3rd ideology that only Asians can see the Asian roots. Theology school system should restructure its westernized method of teaching theology. Western missionaries have left Asian Theology schools with teachings designed in western context and it has effected the spread of the gospel by Asians also using the western approach. Students of theology will appreciate more the teachings of, the gospel when the context is based on their Asian background and experiences. Appreciative students will be potent instruments in the spreading of the truth. Forced poverty as stated earlier has been identified by Aloysius Pieris to hinder the spread of Christianity, which is in contrast to voluntary poverty. Voluntary poverty manifests the features of a true Christian. He who chooses to be poor truly believes in the doctrine and wholeheartedly serves for the spread of the gospe\. He is a selfless servant of the church and tries to live a life that of Jesus Christ. World mission is optimistic that the realization of its vision will be achieved. Asian Christians comprises only less than ten percent (10%) of the Asian population. Despite the Chri stianityis unpopularity in Asia, Korea has reached a majority in number. Recently, statistics shows that twenty five percent (25%) of the Korean population are Christians. Unlike other Asian countries with framed religions such as Japan (Shintoism), India (Hinduism/ Buddism), China (Confucianism), Korea has opened its horizon to other religions, which includes
