200여개의 지역구 선거가 동시에 치러지는 국회의원 선거에서 주요정당의 의석 수를 예상해야 할 필요가 있는데, 이제까지는 정당별로 당선확실 선거구 수에 경합 선거구 수를 적당히 더하는 상식적 수준의 셈에 의존하여 왔다. 그러나 선거 예측 조사 자료를 베이즈 추론의 틀에 넣어 활용함으로써 정당 의석 수에 대한 합리적 점 예측과 구간 예측이 가능하다. 2004년의 제 17대 국회의원 선거에 적용하여 이 방법의 실용성을 살펴보았다.

Recently Hopfield proposed a model for content-addressable memory, which has been shown to be capable of storing information in a distributed fashion and determining the nearest-neighbor. Its application is, however, inherently limited to the case that the number of l's in each stored vector is nearly the same as the number of O's in that vector. If not the case, the model has high probability of failure in finding the nearest-neighbor. In this work, a modification of the Hopfield's model, which works well irrespective of the number of l's (or O's) in each stored vector, is suggested.

Background: Bilateral Tessier number 3 clefts are extremely rare, and their surgical treatments have not been well established. Case presentation: The authors describe the case of a patient with a right Tessier number 3, 11 facial cleft with microphthalmia, a left Tessier number 3 facial cleft with anophthalmia, and cleft palate. We repaired simultaneously the bilateral soft tissue clefts by premaxillary repositioning, cleft lip repair, facial cleft repair by nasal lengthening, midfacial advancement, and an upper eyelid transposition flap with repositioning both the medial canthi. Postoperatively, the patient showed an esthetically acceptable face without unnatural scars. Conclusions: We achieved good results functionally and esthetically by midfacial advancement with facial muscle reposition instead of traditional interdigitating Z-plasties. The surgical modality of our anatomical repair and 3 months follow-up results are presented.

In the case that the average velocity within rectangular-shaped sedimentation basin is less than 1.5cm/sec, and Froude number less than $10^{-6}$, it can not be expected that the longitudinal baffle improves the sedimentation efficiency. Also, since relatively lower velocity increases the effect of geostrophic body force, asymmetric flow pattern on a plane occurs within the basin. From the results of CFD (Computational Fluid Dynamics) simulation, in the case that the highest velocity within rectangular-shaped sedimentation basin is over 1.5cm/sec, and Froude number over $10^{-6}$, it can be expected that the longitudinal baffle installed within rectangular-shaped sedimentation basin improves the sedimentation efficiency.

하이브리드 로켓의 원통형 multi-port 그레인에서 그레인 포트 개수 변화에 따른 연소특성을 고찰하였다. 후퇴율의 경우 그레인 포트 개수가 증가할수록 연료 포트 후퇴율과 끝단면 후퇴율 모두 증가하였다. 성능변수의 경우 그레인 포트 개수가 증가할수록 O/F 비는 낮아졌고, 비추력은 높아졌다.

In recent years in Japan, derelict land by aging fanners has increased at the same time as the desire of city dwellers for a more natural, leisurely lifestyle. In response, an increasing number of citizens' farms(or 'allotment gardens') have opened in and around urban areas. Citizens' farms with overnight accommodation are known as 'kleingartens'. As a case study, we evaluated a kleingarten in the town of Suo-oshima by interviewing the resident caretaker and conducting a questionnaire survey of facility users. Our survey revealed a number of ways in which the facility could be improved to meet user needs. The case study also suggested that kleingartens are an effective means of revitalizing local communities in rural areas.

The purposes of study were to analyze the characteristics of case management network for the homebound elderly in Puchon and to identify major factors that affect the number of network member. The population of this study was social workers who provide services to the elderly. The results show that license of social work and information closeness have a significant effect on the number of network member among the independent variables. This finding is important for case management in the network. As observed in relationship characteristics, the community welfare center established by the university and city government roles in promoting service coordination.

The purpose of this research is to demonstrate the propriety of the locations of the Jigudea(police boxes) through time and spatial analysis. The study area was limited to BusanJingu of Busan city which includes Seo-myeon district; the biggest downtown in Busan city. In this case, monthly crime position occurrence number of times by time analysis, criminal occurrence number of times and the position have some similarities. In case of Jigudea(police boxes) which handle crime, throngs were piled up. The other case of position which crime, there is no Jigudea(police boxes) in group or two were situated. As a result, it is required that Jigudea(police boxes) in Jin-gu should be rearranged and relocated properly.

Regarding all particles at a fixed site as a cluster, the size of the largest cluster under the zero range invariant measures is well studied by Jeon et al.[5] for the case of density one. Here, the density of the finite zero-range process is given by the ratio between the number m of particles and the number n of sites. In this paper, we study the lower density case, i.e., the case m = o(n). Especially, when m ~ $n^{\beta}$,0 < ${\beta}$ < 1, we show that there is an interesting cutoff point around $\beta$ = 1/2.

고도행렬로부터 등고선을 추출하는데 있어, 가장 중요한 문제는 하나의 격자에 네개의 통과점이 발생하는 이상 상황(degenerate case)의 해결이다. 본 논문은 이상 상황 검사와 다음점 결정을 동시에 수행하는 방법을 기술한다. 이 방법은 최소 횟수 의 배열 인덱싱을 필요로 한다. 또한 통과점을 모서리점의 높이차에 따라 LOWER/ HIGHER로 표시하고, 이 정보를 이용하여 보다 적은 횟수의 배열 인덱싱을 필요로하는 방법을 제안한다. 그리고 통과점을 표시하고 이들을 추적하기에 적합한 자료구조를 구체적으로 기술한다.
