당원중심 정당조직이 약화되고 있는 정당정치 변화추세 및 진성당원이 절대 부족한 실정에서 의원이나 원외위원장에 의해 동원되고 있는 당원들이 참여하는 경선의 현실적인 한계를 고려한다면, 당원 이외 유권자도 참여하는 보다 개방적인 경선을 지향할 수밖에 없는 상황이다. 이번에 국민경선의 확대내지는 제도화를 목표로 중앙선관위 및 한나라당과 민주당의 개혁특위가 제시하고 있는 공천안, 특히 모든 유권자가 참여할 수 있는 여야 동시 완전국민경선안은 선거인단을 모집하여 실시하는 기존의 제한적 국민경선보다 불공정한 동원, 역선택 등의 문제 해결에 도움이 되리라 본다. 하지만 여전히 해소되야 할 경선 공정성과 관련된 구조적인 문제는 경선이 치러지는 지역의 정당조직이 비민주적으로 운영되는 데에서 비롯되는 경선 후보들 간의 불균형 문제이며, 전략공천이라는 형태로 치러지는 사실상 하향식 공천 역시 경선 공정성을 크게 훼손할 소지가 있으므로 정당의 전략공천 비율은 더욱 축소되어야 할 것이다. 2012년 총선이 임박한 상황에서 현실적으로 무엇보다 시급한 것은 한나라당, 민주당 모두 공천제도 개혁안을 조속히 확정하고 선관위안을 법제화하는 일이며, 이를 통하여 유권자가 참여하는 정당경선의 제도화가 이루어질 때 최근 시민후보의 등장과 같은 시민사회의 도전으로부터 비롯된 정당정치의 위기상황을 더욱 새로운 정당정치로 나아가는 계기로 전환시키는 일도 보다 용이해 질 것이다.

This paper studies the logic of fiscal constraints and fiscal autonomy in a political agency model with both moral hazard and adverse selection. The electoral process not only disciplines incumbents who may act against the public interest but also opts in politicians who are most likely to act along voters' interests. We characterize perfect Bayesian equilibria under shared tax system and fiscal autonomy with fiscal constraints for local public good provision. It is shown that the local voters' expected welfare under fiscal autonomy is higher than under shared tax system if the same fiscal constraints are applied. In order to examine the effects of party's candidate selection processes on the behavior of local politician and national politician, we extend the model to an environment where local politician can compete for the candidacy of national assembly with incumbent national politician. If local politician wins majority of votes against incumbent national politician, then he can move on to serve as a national politician. Otherwise, his political career will end as a local politician. It is the gist of this primary system portrayed by this setup that local politician and national politician compete to garner more votes. Therefore, primary system as a candidate selection mechanism enhances local residents' welfare compared to top-down candidate selection processes.

Purpose: This study was performed to investigate the difference of meridional visual acuity and the loss of corrected visual acuity (VA) in order to emphasis the importance of astigmatic correction. Methods: 64 subjects (122 eyes) aged $22.75{\pm}2.36years$ participated in this study. After full correction of astigmatic refractive error, VA was measured in which the direction of the slit filter was matched with astigmatic axis and $90^{\circ}$ to the astigmatic axis. Results: 52 eyes showed no difference in VA between the two direction. However 70 eyes had difference VA between them. 14 out of 52 eyes and 24 out of 70 eyes had under 1.0 in monocular VA. The astigmatic degree was higher in the existence of VA difference between the two direction than non-existence. The difference is higher with under 1.0 monocular VA. Monocular VA is closely related to the focal line having better VA in the principal focal line. Glasses replacement period was analyzed as 6~12 months for the preservation of better VA. Conclusions: The final glasses prescription has to be given with full correction because continued under-correction for astigmatism causes meridional VA difference.

Single-layer latticed domes with rigid-joint have an advantage in the construction cost and the aesthetic. But, in single-layer latticed domes, the joints are hard to discriminate between pin-joint and rigid-joint, and consisted of semi-rigid joint in practical. And the erection of large roof structures requires special techniques. As one of these special techniques is the Step-Up erection method. This paper verified buckling characteristics of single-Layer lamella domes according to the Joint flexibility under construction by Step-up method. The results are follows: As erection steps increase, the buckling strength decreases. It is occurred the joint buckling by snap through on the top of dome when the joint flexibility close the rigid. And large tensile stress distribution appeared in circumferential member of bottom boundary when the step of construction is low. As the step of construction increase, large compressive stress distribution showed in the top of dome.

In this study, finite element analysis was performed to evaluate a method of increasing the fatigue life of the pipe connection structure commonly used in the topside structure of offshore platforms. MSC Patran/Nastran, a commercial analysis program, was used, and the critical structural model was selected from the global analysis. To realize the stress concentration phenomenon according to the load, modeling using 8-node solid elements was implemented. The main loads were considered to be two lateral loads and a tensile load on a diagonal pipe. To check the hotspot stress at the main location, a 0.01 mm dummy shell element was applied. After calculating the main stress at the 0.5-t and 1.5-t locations, the stress generated in the weld was estimated through extrapolation. In some sections, this stress was observed to be below the fatigue life that should be satisfied, and reinforcement was required. For reinforcement, a bracket was added to reduce the stress concentration factor where the fatigue life was insufficient without changing the thickness or diameter of the previously designed pipe. Regarding the tensile load, the stress in the bracket toe increased by 23 %, whereas the stress inside and outside of the pipe, which was a problem, decreased by approximately 8 %. Regarding the flexural load, the stress at the bracket toe increased by 3 %, whereas the stress inside and outside of the pipe, which was also a problem, decreased by approximately 48 %. Owing to the new bracket reinforcement, the stress in the bracket toe increased, but the S-N curve itself was better than that of the pipe joint, so it was not a significant problem. The improvement method of fatigue life is expected to be useful; it can efficiently increase the fatigue life while minimizing changes to the initial design.

Background : According to the 2002 consensus report of the American Thoracic Society/European Respiratory Society (ATS/ERS), idiopathic pulmonary fibrosis (IPF) was classified as biopsy proven or probable IPF. Probable IPF is defined as those with distinctive features that allow for a confident diagnosis of IPF/usual interstitial pneumonia (UIP) within an appropriate clinical setting. The determination of the clinical course of probable IPF, as diagnosed by the ATS/ERS criteria, was studied. Methods : Between March 1995 and August 2002, 36 patients with probable IPF, from two tertiary referral hospitals, were enrolled in this study. The clinical characteristics, prognostic factors and treatment efficacy of these patients were retrospectively evaluated. Results : The mean age of the subjects was $65{\pm}6$ years. The one and 3 year survival rates were 82.4 and 50.3%, respectively, and a median survival period of 42.0 months. The total cell count of bronchoalveolar lavage was higher in the death than the survival group (p<0.05). No survival benefits were found in the cytoxan and steroid treatment groups compared with other treatment groups. Conclusion : These results suggest that the clinical course of probable IPF may be similar to that of biopsy-proven UIP. However, atypical patients must undergo an open lung biopsy for confirmation of the diagnosis.

Background : Residual pleural thickening (RPT) is the most common complication of tuberculous pleurisy (TP), despite adequate anti-tuberculous chemotherapy. At the conclusion of treatment, 43-50% of patients present RPT, with its incidence varying according to the time of evaluation. To assess the spontaneous resolution of RPT, the RPT at the completion of treatment was compared with that at the final follow-up. The factors related to the development of RPT after the completion of treatment were also studied. Methods : The medical records of sixty four patients, diagnosed with TP between March 2001 and June 2003, were retrospectively. The RPT was measured at the completion of treatment and at the time of the final follow-up and the degree and frequency of RPT compared between the two measurements. Each time, the patients were divided into two groups: those with and without RPT. The clinical characteristics and the radiographic and pleural fluid findings of the two groups were compared. Results : Thirty six (56%) and 27 patients had RPT at the completion of treatment and at the time of the final follow-up, respectively (median follow up period: 8 months). Spontaneous resolution of the RPT was found in 9 patients (24%), and had decrease below 10mm in 15 (42%) during the follow-up period after treatment. The patients were initially divided into two groups: 36 and 27 patients with and without RPT, respectively. There was no predicting factor of RPT, with the exception of the presence of CRP, between the two groups. The patients were also separated into two groups at the time of final visit: 27 and 37 patients with and without RPT, respectively. The patients with RPT were found to have a lower total WBC count in pleural fluid. Conclusion : 57% of patients with RPT were found to have spontaneous resolution of the residual pleural thickening after completion of the chemotherapy. The time of evaluation for RPT and its predicting factors were decided after adequate follow-up, irrespective of the completion of treatment.
