Purpose of study: The purpose of this study is to analyze the origins and texts of the Jewish scriptures, the Mishnah Moed, and to examine them from the perspective of educational theology to suggest practical application methods for Christian education. Research content and method: In order to achieve the purpose of the research, the contents were set as follows. First, for analyzing the origin and text of Mishnah Moed, the historical process until Mishnah Moed was edited was reviewed, and the contents of the text of Mishnah Moed were classified into 2 groups of 12 Masekkot from the viewpoint of the researcher; The first group is the contents Shabbath and Festivals : Shabbat, Pesahim, Yoma, Sukkah, Rosh haShanah, Megillah and the other group is as a rule to keep the festival, Erubin, Sheqalim, Betzah, Taanith, Moed Qatan, Hagigah. Second, in order to analyze the mishnah moed in educational theology, the church calendar for the festivals currently used in Christianity was analyzed by dividing it into the origin of the church year, the contents of the church year, and the scriptures of the church year. Third, as an educational model for applying Mishnah Moed to Christian education, the goal of seasonal education, the content of seasonal education, and the method of seasonal education were presented. Conclusions and Suggestions: The conclusion of the research is as follows; First, seasonal education based on the teachings of the Bible must be conducted within the Christian community. Second, The education is needed for leading a life that correctly understands and practices the historical process of the Christian festivals. Third, various church education programs should be developed and utilized according to the Christian Bible routine. Fourth, numerous symbols symbolizing the Christian festivals must be created and educated. Fifth, except for the festivals of the sufferings of Jesus Christ, the rest of the festivals must be observed as Celebration.

Edward's syndrome is a genetic disorder of 18th chromosomal trisomy. Main clinical features of this syndrome include systemic conditions, such as mental retardation, growth retardation, dyspnea, congenital heart disease, and orthopedic disorders, such as flexion deformity and rocker-bottom feet. The characteristics of fetal abnormality are hydramnios, small placenta, common umbilical artery. Infants with Edward's syndrome have very low survival rate. Almost half of them die during fetal stage. Fifty percent of them survive 2 months, and 5 to 10 percent of them survive about 1 year. A 3-year and 7 month old girl visited our dental hospital for the treatment of dental caries. Considering her systemic disease, low body weight, medical history of cardiac surgery, and difficulty in airway management, dental procedure was performed under general anesthesia. We report this case with review of literatures.

Edwardsiellosis is difficult to treat in cultured olive flounder, Paralichthys olivaceus. It is present in the fish for a long period during all growth stages, and it often leads to mass mortalites. In this paper, the clinical patterns of Edwardsiellosis were analyzed by dividing the data into the whole-water temperature, low-water temperature, low-high water temperature, high-water temperature, and high-low water temperature groups based on various clinical signs of diseased cultured olive flounder using a decision tree technique. In the clinical sign patterns in the decision trees analyzed in the experiment, clinical signs in the liver, such as liver nodules, liver hemorrhages, and liver degeneration, were selected as the criteria for determining Edwardsiellosis. The selected clinical signs were known as the major clinical signs of Edwardsiellosis, and through consultation with fishery disease experts, the analysis confirmed that the clinical signs of Edwardsiellosis were successfully found in this study.

문학과 음악처럼 다른 두 예술 분야에서는 필연적으로 발생하는 시대별 표현방법의 변화에서 공통점이 발견되기 마련이다. 시기적으로는 고전주의적 표현에서 낭만주의적 표현으로의 변화를 겪은 18-19 세기 영, 미 문학의 표현 형태와 20세기 중반 미국재즈의 획기적인 표현방법상의 변화에서 공통점을 발견할 수 있다. 1846년, 제약과 규범의 틀을 탈피한 인간 중심의 자기 주도적 표현 방식을 보인 낭만주의적 성향이 만연한 시기에 모든 창작은 계산에 의해 나와야한다는 에드거 앨런 포우의 한 비평문이 소개된다. 신고전주의적 사상의 출발로 볼 수 있을 정도인 이 비평문에서 포우는 작가의 순간적 감정을 자제시키면서 창작은 사전 준비에 의해서만 행해져야한다는 주장을 한다. 이 연구는 포우가 비평문을 통하여 주장하는 사상을 마일즈 데이비스의 작품 속에서 의도적 창작의 개연성을 연계하여 유추하는 것에 중심을 둔다.

We proposed the context-awareness routing algorithm DDV (Dynamic Direction Vector)-hop algorithm at Mobile Ad-hoc Network(MANET). MANET has problem about dynamic topology, the lack of scalability of the network by mobile of node. By mobile of node, energy consumption rate is different. So it is important choosing routing algorithms for the minium of energy consumption rate. DDV-hop algorithms considers of the attribute of mobile node, create a cluster and maintain. And it provides a path by searching a route more energy efficient. We apply mobile of node by direction and time, the alogorighm of routning path and energy efficiency clustering is provided, it is shown the result of enery consumption that is optimized for the network.

In this paper, we evaluate and compare performance between position-based and non-position-based routing protocols in a vehicular ad-hoc network. The protocols evaluated in this paper for many performance evaluation aspects are a position-based routing protocol, GPSR (Greedy Perimeter Stateless Routing), and the non-position-based such as AODV (Ad-hoc On-Demand Distance Vector) and DSR (Dynamic Source Routing) protocols. The three protocol characteristics such as Packet Delivery Ratio, Latency of first packet per connection, and Average number of hops depending on distance are compared and evaluated. As the result of simulation, the AODV performed better than the DSR. However, due to the high mobility characteristic of a vehicular ad-hoc network, GPSR, the position-based routing performs better than the non-position-based routing protocols such as AODV and DSR in a vehicular ad-hoc network environment.

본 논문에서는 다수의 소형 무인 항공기(UAV) 그룹이 이동 중 장애물을 만났을 때 장애물과의 충돌을 방지하는 효율적인 장애물 회피 정책을 제안한다. 이 정책은 무선 에드혹(moblie ad hoc) 네트워크를 기반으로 단순히 UAV 간의 충돌 회피 뿐만이 아니라 UAV 그룹이 이동하는 도중 장애물을 발견 하였을 경우 장애물을 효율적으로 회피하는 방법과 연결성이 손실되는 경우에 대처하는 방안도 고려하였다. 제안하는 정책은 UAV가 장애물을 포착 하였을 때 현재 이동 속도를 유지한 채 장애물을 기준으로 UAV 그룹을 2개의 그룹으로 분리하여 장애물을 회피 한 후 일정한 지점에서 모여 다시 각 UAV간의 연결성을 유지한 채 목표물을 향해 이동하는 정책을 제안한다.

Geocasting is a form of communication that transmits messages to all nodes within a given geographical region(i.e., the geocasting region). Most of conventional onery aware protocols were based on shortest-hop routing that is, they minimized the cost in terms of the distance and total transmission energy not considering both the residual energy at each node and the link error ratio when selecting the routes for communication. In this paper we propose a MLRG(Maximum Lifetime Reliable Geocast) protocol for energy-efficient and reliable geocasting in Ad-hoc networks. The proposed MLRG, a position-based and routing-based geocasting algorithm, maximizes the network lifetime using newly defined cost function and selecting the energy balanced routes on the basis of each node's residual energy, and provides a reliable communication considering the link error ratio.

In this paper, we propose and implement a hybrid-type video conference system using SIP protocol proposed in IEFT. This conference system, all signaling is controled by the server, while the media communication can be managed either by UAs or by the server. as a result, the complexity of its routing and user state management is reduced and it is applicable to the mobile environment of the ad-hoc models. The implemented server is scale enough to be used in a large conference because it only takes charge of signaling part. And also we see that UAs are only suitable in the small conference where less than ten people can join.

Geographic forwarding algorithms을 사용하는 Georouting protocol에서는 route maintenance을 위해서 고정된 주기마다 beacon message을 이웃노드에 전송하는 fixed periodical beacon based route algorithm을 사용하여 mobile node 정보를 습득한다. Fixed periodical beacon scheme에서의 기존 연구 이슈는 이웃노드 정보의 신뢰성을 유지하기 위해서 다양한 mobility environment 환경에 맞도록 beacon 전송주기를 적절히 결정하는 연구가 진행되어 왔다. 이와 같은 연구에서는 long periodical interval 사용 시 이웃노드의 위치정보 error을 발생시킬 확률이 높으며 또한 short periodical interval 의 경우 네트워크 내에 high route overhead 을 유발시키는 단점을 가지고 있다. 따라서 고정된 주기 방법은 다양한 mobility environment에 잘 적용되지 못하며 또한 mobility environment 에서 발생하는 route maintenance 내에 이웃노드 정보에 대한 불확실성 문제가 빈번이 발생하여 경로 설정에 잘못된 정보를 제공하여 경로 신뢰성(path reliability)과 낮은 전송률 (transmission rate)을 야기한다. 본 논문에서는 이런 이웃노드 정보의 불확실성 문제를 극복하기 위해서 mobile node가 스스로 자신의 위치를 체크하여 routing table을 능동적으로 갱신하는 방법을 이용하여 이 문제를 극복할 수 있도록 하였다. 모의 실험은 ns2를 이용하여 실시하였으며 결과는 low/high mobility scenario에서는 기존 방법 보다 routing overhead 을 줄이면서 높은 전송률 (transmission rate)을 보인다.
