Purpose and Method: Financial field among the various changes due to the nationalization of fire fighting officials is the main point and to stably settle according to the purpose, improvement of special account for fire fighting officials is suggested by analyzing the facts and related acts. Results: To use the fire fighting project budget entirely in fire fire fighting project by the purpose of the installation of special account for fire fighting officials, dual budgeting standard for labor cost should be revised. In the reserve cost budgeting standard "Within 1/100 of the total budget rule" total budget includes the labor cost, as a result reserve cost budget will keep increase, so reserve cost budget should be fixed by the project budget instead of the total budget. Conclusion: To use the fire fighting budget by the purpose of the installation of special account for fire fighting officials, improvement on budgeting standard is necessary to increase quality of the fire service and stably operate the fire fighting organization.

The purpose of this study is to find out the measures to improve the curriculums of the specialized vocational high schools aided by Small and Medium Business Administration through estimating whether they have satisfied the purpose of the aids and analyzing the related factors. Among specialized vocational high schools aided by Small and Medium Business Administration, 49 technical high schools which comprised the largest proportion were chosen as subjects for this study. Among the 49 subjects, 57.1%(28 schools) are reported to be suitable, 36.7%(18 schools) so-so, and 6.2%(3 schools) unsuitable for the curriculums. The curriculums of specialized vocational high schools aided by Small and Medium Business Administration were mostly associated with the local strategic business. However, many of them implemented the pre-existed curriculums because they didn't reflect the job analysis of the business properly. To establish more effective curriculums of the specialized vocational high schools aided by Small and Medium Business Administration, most of all, guides for them should be prepared in its level. Also, midium and long-term development plans of school departments should be made to reorganize the current departments which hinder the specialization in curriculums by government or offices of education. Finally, a conference of government departments on the curriculum establishment should be organized.

지금까지, 천의 주관적인 태평가는 역학적인 특성에 의하여 결정된다고 연구되고 있다. 특히 KES-FB 시스템은 천의 역학적인 특성을 통계학적인 방법으로 객관화한 소프트웨어이다[1], 대체적으로 직물에 비해 편성물은 측정의 어려옴, 지역적인 기후특성, 문화적인 차이 때문에 태를 평가하는데 적용하기 난해한 면이 있다[2]. 종합적인 태는 천의 사용 용도와 사람의 정신적인 특성에 대한 반영이 개입되어야 하므로 적용하기에 곤란하지만, 최근에 응용되고 있는 퍼지이론과 신경망이론을 통하여 전체적인 태평가가 가능하리라 본다. (중략)

본 논문은 개인별 프로그램 선호도와 채널 선호도를 기반으로 프로그램을 추천해주는 선호프로그램편성표를 구성하여 이를 효과적으로 보여주는 사용자인터페이스(UI) 모델을 제안한다. 현재 개인 맞춤화 전자프로그램가이드(PEPG)에 대한 다양한 연구가 이루어지고 있으나 주로 추천 알고리즘 연구에 그 초점이 맞춰져 있는 실정이다. 동일한 추천 알고리즘에 의해 추출된 프로그램이라 할지라도 정렬 순서와 디스플레이 방법에 따라 편성표를 이용하는 사용자의 용이성이 달라질 수 있다. 이에 본 논문은 추천 알고리즘에 의해 추출된 프로그램들의 선호도에 현재시간 기준으로 가중치를 부과하여 그 프로그램들의 선호도를 합산한 값으로 정렬한 편성표를 구성하였다. 이러한 선호프로그램편성표는 시청자가 가장 선호하는 프로그램과 채널이 최우선으로 보여지게 되므로 쉽고 빠르게 원하는 프로그램을 찾아갈 수 있다는 장점이 있다. 따라서, 사용자는 원하는 프로그램이 시작할 때까지 기다리거나 하는 시간의 낭비없이 시청이 가능하다. 본 논문을 통해 향후 등장하게 될 많은 개인 맞춤화된 서비스들을 개발하는데 도움이 될 수 있길 바란다.

In this study, we evaluate the braking performance of an urban railway vehicle to verify its basic safety condition. The braking performance evaluation methods, deceleration measurement and braked weight percentage, were compared for trains with different numbers of cars, in order to assess the advantages of each method and their compatibility. With a probabilistic braking model, the effect of the adhesion coefficient distribution was analyzed in accordance with the train composition. A train with many cars has a narrower deceleration distribution width than one with few cars. The braked weight percentage method is expected to be useful in the design of train signal systems, because it allows the braking distance to be calculated for various initial brake velocities. The deceleration distribution model and its results are expected to be useful as a basis for precise train signal design.

This study looked into coping strategies of local terrestrial broadcasting companies in the media market, since the introduction of comprehensive programming channels was confirmed. Local terrestrial broadcasting companies vulnerable to market competitiveness are driven more out to the difficulty of survival in a limited advertising market with the advent of comprehensive programming channel. and Local terrestrial broadcasting receive discriminative application than comprehensive programming channel. They have reverse discrimination in must-carry, broadcasting area, programming regulation, advertisement regulation, broadcasting development fund. Hence, Local terrestrial broadcasting needs diverse countermeasures at difficult media circumstances. Above all, Competitive content reinforcement is desperately needed. That's why content distribution structure needs diversification. And, It is necessary for local terrestrial broadcasting companies to diversify the content distribution system. As a way to expand distribution structure of local broadcasting, the introduction of local programming regulations for total amount will be highlighted in the nationwide network program. The mandatory policy that programs produced by local terrestrial broadcasting companies will be broadcast regularly in prime time through a nationwide network is an example. In addition to developing high content independently, 2nd Multiple channels of distribution is needed. It has to be supplied to various platforms including local broadcasting, SO and etc. In addition, it is necessary to activate regional co-production program between local terrestrial broadcasting companies and regions. Time rate between central stations and local terrestrial broadcasting companies must be distributed practically. And also, local terrestrial broadcasting companies in addition to ad revenue model to themselves and their own businesses by expanding the sponsorship to strengthen the competitiveness will have to nurture self-sustaining. Moreover they must have enlarge economy of scale through widen of broadcasting area.

This paper presents a mathematical model for a double-fleet operation in Korean high speed rail (HSR). KORAIL has a plan to launch new HSR units in 2010, which are composed of 10 railcars. The double-fleet operation assigns a single-unit or two-unit fleet to a segment, accommodating demand fluctuation. The proposed model assumes stochastic demand and uses chance-constrained constraints to assure a preset service level. It can be used in the tactical planning stage of the rail management as it includes several real-world conditions, such as the capacities of the infra-structures and operational procedures. In the solution approach, the expected revenue in the objective function is linearized by using expected marginal revenue, and the chance-constrained constraints are linearized by assuming that demands are normally distributed. Subsequently, the model can be solved by a mixed-integer linear programming solver fur small size problems. The test results of the model applied to Friday morning train schedules for one month sample data from KTX operation in 2004 shows that the proposed model could be utilized to determine the effectiveness of double-fleet operation, which could significantly increase the expected profit and seat utilization rates when properly maneuvered.

There remains controversy regarding the appropriate surgical treatment for coarctation of the aorta because of relatively high rate of recoartation and high mortality in the cases associated with complex anomalies. We evaluated 31 consecutive patients who underwent surgical repair of coarctation of the aorta from May 1992 through June 1996. Nineteen patients(61.3%) were neonates and 26(83.9%) were under three months. Nine patients did not have major associated anom lies(Group I), 15 patients had ventricular septal defect(Group II), and 7 patients had major complex anomalies(Group III). 35.5% of the patients had arch hypoplasia. Surgical procedures performed were as follows: extended end-to-end anastomosis in 17 patients, combined resection-flap procedure in 7 patients, and subclavian flap aortoplasty in 7 patients. Residual coarctation occurred in 7(25%) of 28 patients; 2 after subclavian (lap aortoplasty(2/6, 33.3%), none after combillrd resection-flap procedure(0/7, 0%), and 5 after extended end-to-end anastomosis(5/15, 33.3%). Higher incidence of residual coarctation was noticed in the group with arch hypoplasia. The incidence of postoperative coarctation at a mean follow-up of 20.5 months in survivals was 12.0%(3/25); 2 cases after subclavian flap aortoplasty(2/6, 33.3%), none after combined resection-flap procedure(017, 0%), and one after endtoend anastomosis(1/12, 8.3%). The mortality rate related to coarctation repair was 9.7%(3 patients all in Group III). This study revealed that isolated coarctation of aorta and coarctation with ventricular septal di3fect(groups I & ll) can be repaired with low mortality, but repair of coarctation with complex anomaly had a high operative mortality Also the patients with arch hypoplasia had higher incidence of post-operative residual coarctation.
