Shalish is a key ingredient of the dispute resolution culture in Bangladesh since a formal court system has been known to show inefficiencies, such as overburdened cases and litigation process delays. This paper investigates the main function of Shalish and examines the evolution of Shalish in the perspectives of its three variants: a community-based Shalish, a village court, and an NGO variant of Shalish in modern extensions. It was found that traditional Shalish may play a role in the dispute resolution system in modern villages. A village court is a kind of hybrid dispute resolution system combining an informal dispute resolution with a formal court system. A village court is administered by the Union Parishad without intervention from the central government. Both the Shalish and village court have the weakness of unfair verdict exercised by local elders within a community. For this reason, an NGO variant Shalish is to reflect voices of women and other lower people in the community. To this study's interpretation, a village court is a new kind of Shalish combined with a formal court system while an NGO variant Shalish is also a "new" Shalish combined with a mediation system. In this respect, core elements of Shalish tradition have not been changed although various forms of new dispute resolution systems have emerged in the modern world.

This paper proposes the cell scheduling algorithm proper to high-speed ATM switch. The proposed algorithm is the VRR(Variable weight Round Robin) combined the FRR to variant QLT. The FRR performs the cell service of the fixed weight by each buffer. So, FRR don't support the QoS of ATM service classes although it is easy to implement a high speed switch. VRR uses the method expaned to variable weight according to buffer state as well as schedules the cell according the Fixed weight based FRR. The simulation to evaluate the proposed algorithm was done by AweSim arid Visual C++. The result graphs show that the proposed algorithm is excellent, especially in the aspect of cell loss. This area is engaged by English Abstract.

본 논문에서는 Web Lecture script를 정의하고 이를 효과적으로 운영하기 위한 Java Web Server를 설계 구현하였다. Web Lecture Script란 강의록, 문제출제, 문제 평가, 숙제 제출, 자료실, 토론방 등의 가상 대학 환경을 편리하게 구축하기 위해서 데이터베이스 및 파일의 접근을 Web 환경의 script막을 사통하여 구현할 수 있도록 정의한 것이다. Lecture시스템은 사용자에게 정형화된 포맷이 많이 쓰이기 때문에 script로 정형화된 형태의 인터페이스가 적합하며, 실제적인 구현이 Jaya로 이루어지기 때문에 확장의 범위가 크다. Web Server는 이러한 Lecture Script를 사용자에게 제공하기 위한 Script Engine을 포함하고 있어야 하는데, 이러한 Script Engine이 Web Server라 어떻게 상호작용 하는가에 따라 성능이 좌우된다. 상호 작용하는 방법에는 Script Engine이 Web Server 자체에 포함될 경우, 독립적인 프로세서를 띄워서 처리하는 방법 스크립트만을 처리하는 별도의 서버를 두어 처리를 전환하는 방법이 있다. 따라서 Lecture Script 처리 Engine은 여러 방법으로 구현하고 성능을 비교하여 보다 효과적인 서버를 제안하고자 한다.

The modeling of thermodynamic non-idealities and transport anomalies is a crucial prerequisite to realistically simulate the mixing and combustion processes of liquid propellants injected above critical pressures. This study has developed a specific set of subroutines to calculate the thermodynamic and transport properties based on the generalized cubic equation of state (EoS) in a coupled manner with the standard chemical kinetics packages (Chemkin). The existing flamelet analysis code is extended with the real-fluid package and applied to numerical investigation of local flame structures of kerosene and liquid oxygen at high pressure conditions relevant to the actual rocket engines.

This paper presents a computational fluid dynamics (CFD) analysis to investiagate the effect of expansion chamber on overpressure reduction in protective tunnels subjected to detonation of high explosives. A commercial CFD code, Viper::Blast, was used to model the blast waves in a protective tunnel with a length of 160 m, width of 8.9 m and height of 7.2 m. Blast scenarios and simulation matrix were establihsed in consideration of the design parameters of expansion chamber, including the chamber lengths of 6.1 m to 12.1 m, widths of 10.7 m to 97 m, length to width ratios of 0.0 to 5.0, heights of 8.0 m and 14.9 m, and ratios of chamber to tunnel width of 1.2 to 10.9 m. A charge weight of TNT of 1000 kg was used. The mesh sizes of the numerical model of the protective tunnel were determined based on a mesh convergence study. A parametric study based on the simulation matrix was performed using the proposed CFD tunnel model and the optimized shape of expansion chamber of the considered tunnel was then proposed based on the numerical results. Design recommendations for the use of expansion chamber in protective tunnel under blast loads to reduce the internal overpressures were finally provided.

Background: There are various etiologies causing bronchiectasis, but the cases without definite causes account for a quite high proportion. It is also uncertain that immunoglobulin G subclass deficiency (IgGSD) is associated with bronchiectasis. Therefore, we tried to measure the frequency of IgGSD in patients with bronchiectasis of unclear etiology, and to observe the clinical features of those patients with bronchiectasis and IgGSD. Methods: For the outpatients of a university hospital who were diagnosed as bronchiectasis by chest CT, we produced comprehensive history taking and physical examinations, and finally selected 31 patients with bronchiectasis of unclear etiology. Results: Two patients had total immunoglobulin G deficiency. The frequency of IgGSD was comparatively high (n=14). When we compared IgGSD group to normal immunoglobulin G subclass group, there were no significant differences in sex, age, and the frequency of sinusitis, bronchial asthma, and the abnormal lung function. Conclusion: In cases of bronchiectasis without definite causes, it can be considered to measure the level of immunoglobulin G subclass. It is also probably worthwhile to further evaluate the relationship between IgGSD and bronchiectasis.

To understand the clinical results of aortic root replacement with either inclusion or open technique, we analysed 53 patients who underwent replacement of the aortic root with composite graft between October,1980, and May, 1995. Annuloaortic ectasia was the most common indication for operation(29 patients), follwed by aortic dissection(22 patients). Among 53 patients, 19(35%) had Marfan syndrome. Three patients died during hospitalization (Mortality: 5.5%). The follow up was possible in 48 patients(Follow-up rate; 94%,mean duration;37 months). The actuarial survival rate at 24 months was 95% in open technique group, and 87% in inclusion technique group. Late complications developed in 10 patients. Dissecting aneurysm in the remaining aorta was noted in 3 patients with inclu ion 1,schnique, and a pseudoaneurysm from coronary artery anastomosis site developed in a patient with inclusion technique. In conclusion, there was no statistical differences in survival for 24 months between inclusion technique and open technique group. But late problems in the remaining aorta or death from unknown cause occurred with moderate frequency : careful follow-up after aortic root replacement thought to be important for long term survival.

To support the QoS streams for large scale clients, the internal resources of VOD servers should be utilized based on the characteristics of the streaming media service. Among the various resources in the server, the main memory is used for the buffer space to the media data loaded from the disks and the buffer hit ratio has a great impact upon the server performance. However, if the buffer data with high hit ratio are replaced for the new media data as a result of the number of clients and the required movie titles are increased, the negative impact on the scalability of server performance is occurred. To address this problem, the buffer replacement policy considers the intrinsic characteristics of the streaming media such as the sequential access to large volume data and the highly disproportionate preference to specific movies. In this paper, the preference-based segment buffer replacement policy is proposed in the cluster-based VOD server to exploit the characteristics of the streaming media. Since the proposed method reflects both the temporal locality by the clients' preference and the spatial locality by the sequential access to media data, the buffer hit ratio would be improved as compared to the existing buffer replacement policy. The enhanced buffer hit ratio causes the fact that the performance scalability of the cluster-based VOD server is linearly improved as the number of cluster nodes is increased.

Purpose : To find the risk factors associated with coronory artery lesions, non-responsiveness to intravenous immunoglobulin(IVIG) treatment, and recurrences in Kawasaki disease patients. Methods : We retrospectively analyzed 1,000 Kawasaki disease patients who were admitted to Yonsei University Medical Center from September 1990 to December 2003. We compared between responder and non-responder groups to IVIG treatment as well as between relapsed and non-relapsed groups, and as to the relapsed group, we also compared variables between patients in their first and second attack states. Finally, factors associated with longer-fever duration from disease onset were evaluated. Results : Longer fever durations before and after IVIG treatment, male sex, lower Hgb and Hct level, higher WBC count and segmented WBC proportion, and higher CRP and Harada's score were related with coronary artery lesions. Non-responsiveness was related to higher WBC count, segmented WBC proportion, CRP, SGPT, Harada's score, and pyuria. Moderate-to-severe coronary artery dilatations and recurrences were more commonly seen among the non-responder group. No significant predictive factors for recurrence were found. In the relapsed group, lower WBC count, CRP, and shorter fever duration from disease onset were observed in their second attack state. Fever duration from disease onset showed positive correlation with WBC count, CRP, and Harada's score and negative correlation with Hgb levels. Conclusion : Higher WBC count, CRP, and higher Harada's score were related to both higher incidences of coronary artery lesions and non-responsiveness to IVIG treatment, and these factors were also related with longer fever duration. Non-responders to IVIG treatment showed higher recurrence rate and more moderate-to-severe coronary artery dilatations than responders.
