다단계 동적계획법에 의한 평면 철골트러스의 최소중량설계에 관한 연구
金鍾聲,崔宰赫 慶一大學校 1999 論文集 Vol.16 No.2
The aim of this paper is to develope an algorithm of the structural analysis and optimal limit state design for plane steel truss with the joint flexibility by the sequential unconstrained minimization techniques(SUMT) and multi-level dynamic programming techniques. The applicability and efficiency of algorithms developed in this study is tested for 10 membed trusse which has the different joint flexibility. Optimization of the truss is done by nonlinear optimum SUMT method, the objective function considered is the weight of steel bar and the constraints for optimum design are the design limits such as axial force strength, maximum slenderness, minimum thickness, allowable deflection and ratio of the external diameter to thickness of the circular tube bars.

The development of recent science technology and computer application technology has brought many changes in our society The interest in using computers for foreign language education has been emphasized due to these continuing development in technology and social changes. Therefore, the role of the teachers has increased since the early 1990s. Today CMC is concerned with communication between two or more participants via a computer in foreign language education. This study suggests that the teacher's role is very critical in new foreign language education through CMC and this article recommends :The first thing is the roles of teachers such as teachers training, political concern,, financial supports, social and cultural aspects, teachers themselves, and positive CMC activity. The second is to develop the special programs for the English to make new studying circle through the Internet, and to support group study using foreign language. In conclusion, the teachers should guide their students in their studying English by using CMC which is supported by various groups in our society.

The purpose of this thesis is to analyze the authoring tools which can be used for the efficiency of English instruction. We have some steps for this analysis. The first one is to analyze the functions of English learning. The second one is to improve the software function for English learning through a comparative study between the Authorware 5.0 program and the PASS2000 1.0 program. The final one is to recommend directions for English learning in the framework of authoring tools. The first result of the comparative study is that the PASS2000 is more effective than the Authorware in English learning. The PASS2000 authoring tool has many advantages in authoring English education material. But this program will need to improve its functions by analysing the method of English learning in listening, speaking, reading, writing.

Multicast protoclos are developed in order to support group communications, such as remote multimedia conferencing, distributed applicatons and shared whiteboard systems. Multicast protocols can be divided into two groups, such as network-layer protocols and transport-layer protocols. Recently, transport-layer multicast protocols attracted much attention for guaranteeing reliable end-to-end multicast transmission over the Internet. In this paper, we developed the transport-layer multicast protocols called RAMP(Reliable Adaptive Multicast Protocol) and investigated its performance. In order to incarnate the functions of a sender and a receiver for the RAMP protocol, we developed RAMP package operating on the RMF(Reliable Multicast Framework) using Java language. We also simulated the efficiency of the RAMP for unicast and multicast transmission. We found that the RAMP guarantees reliable and efficient multicast transmission over an unstable network conditions.

편측 안면경련은 편측 안면근의 불수의적, 간헐적 수축으로서 심할 경우 안면 근력 약화 및 강직현상등이 나타나기도 하는 질환이다. 서양의학에서 편측 안면경련의 병태생리에 대한 가설은 크게 두가지로 대별되는데, 첫째는 중추성 가설(핵가설)이고, 둘째는 말초성가설이다. 치료방법은 대별하여 내과적 치료와 외과적 치료의 나눌 수 있는데, 외과적 치료가 다양하게 시행되어 왔으며, 근래에는 두개강내 미세혈관 감압술이 시행되고 있다. 韓醫學에서는 眼瞼痙攣울 眼胞振跳, 胞輪振跳라고 하고, 眼眉跳라고도 하며, 그 외 目瞬, 目跳, 眼皮跳 등의 이름으로도 불리운다. 外因으로는 風邪가 經絡에 侵入하는 것이며, 內因으로는 肝血虛한 中의 風邪가 兼하기 때문이다 따라서, 국부경혈 자침과 함께 장부변증에 따라 肝, 膽經 경혈의 사용과 합께 耳鍼T의 시술이 유용할 것으로 사료된다. Hemifacial spasm including blepharospasm is characterized by spontaneous clonic and tonic muscle spasm on one side of the face with synkinesis. Though the etiology of hemifacial spasm is not entirely understood, generally there are two. One is nuclear hypothesis and the other is peripheral hypothesis. There are two ways of treatment of hemifacial spasm. One is internal medicine and the other is operative method. In oriental medicine, hemifacial spasm is very similar to diseases such as Anpojindo(眼胞振跳), Poryunjindo(胞輪振跳), or Anmido(眼眉跳) in symptoms. The diseases such as Anpojindo(眼胞振跳), Poryunjindo(胞輪振跳), Anmido(眼眉跳) is related to the function of liver(肝) and risk factors are regarded as Pung(風). The acupuncture therapy of hemifacial spasm is based on Liver meridian(LV), Gallbladder meridian(GB), And ear-acupuncture is recommended as a good method for hemifacial spasm.
Mobile Data Offloading: A Host-Based Distributed Mobility Management Approach
Jong-Hyouk Lee,Singh, Kamal Deep,Bonnin, Jean-Marie,Sangheon Pack IEEE 2014 IEEE internet computing Vol.18 No.1
<P>The increasing use of mobile devices has resulted in an explosion in mobile Internet traffic. To cope with this growth, mobile network architectures are becoming flatter, and IP mobility support protocols must evolve along with them. The authors propose an IP mobility support protocol that doesn't rely on a single mobility anchor, but rather uses distributed mobility anchors to overcome existing protocols' limitations while providing selective data offloading. They highlight their protocol's main features and strengths through qualitative comparisons and simulations.</P>

Purpose To assess the outcomes of single-stage surgery following fluoroscopic stent placement for malignant colorectal obstruction. Materials and Methods This retrospective study included 46 patients (28 male and 18 female; mean age, 67.2 years) who had undergone fluoroscopic stent placement followed by laparoscopic resection (n = 31) or open surgery (n = 15) for malignant colorectal obstruction. The surgical outcomes were analyzed and compared. After a mean follow-up of 38.9 months, the recurrence-free and overall survival were estimated, and prognostic factors were evaluated. Results The mean interval between stent placement and surgery was 10.2 days. Primary anastomosis was possible in all patients. The mean postoperative length of hospitalization was 11.0 days. Bowel perforation was detected in six patients (13.0%). During the follow-up, ten patients (21.7%) developed recurrence; these included five of the six patients with bowel perforation. Bowel perforation had a significant effect on recurrence-free survival (p = 0.010). Conclusion Single-stage surgery following fluoroscopic stent placement may be effective for treating malignant colorectal obstruction. Stent-related bowel perforation is a significant predictive factor for tumor recurrence.
