The use of local product foods and fresh-cut products, the dietitian's recognition, the required items and the quality for school foodservice was investigated to increase the consumption of high-quality agricultural products. Data from 578 elementary schools, 228 middle schools and 116 high schools were collected by school foodservice personnels in each regional Education Administration in Gyeong-gi province. The first criteria of buying food materials was reliability/safety for all school foodservice. The second criteria were the origin of the product and freshness/ripeness for elementary and middle schools and high school, respectively. The most important consideration for selecting a supplier was the quality of the material. The appearance/status of the food was the first factor for buying food materials. The origin and the seasonality were very important for buying farm products. Dietitians in Gyeong-gi province recognized the local products, and used them weekly. The advantages of using local products were the quick supply, freshness and safety. On the other hand, the disadvantages were the lack of information and the uncertainty of supply. Sixty eight percent of the subjects had experienced the high-quality agricultural products in school meals, but the frequency was low. The main reasons for not servicing high-quality agricultural products were the high cost and the lack of trust on the quality. Among fresh-cut products, seasonings and root vegetables were purchased most frequently, but leaf vegetables was 5.7% only. The purchase of fresh-cut products was not frequent, but usually satisfied. The advantages of fresh-cut products were the reduced workload and waste, but the reason for not using them were poor hygiene and the high price. The diverse supply system and the promotion of the local product foods would be necessary since the most food materials were purchased through suppliers. In addition, the problems related to the high cost and distrust should be resolved to expand the consumption of the high-quality agricultural products and the fresh-cut vegetables. The institutions for certifying the quality should be needed to increase the confidence of these products.

계층화분석과정(analytic hierarchy process, AHP)는 쌍대비교를 이용하여, 사람들의 판단기준을 객관적인 수치로 변환해준다. 그런데 너무 많은 쌍대비교를 필요로 한다는 점이 문제이다. 본 연구의 목적은 표준 AHP보다 간편하면서도, 결과물은 유사하게 나오는 새로운 방식의 의사결정지원시스템을 만드는 것이다. 기존 연구들은 복잡한 쌍대비교 과정을 감소시키기 위하여 과정 분리(process separation) 방식을 가장 많이 사용하였다. 본 연구가 채택한 과정 분리 방법은 "분리와 혼합 방식"이다. 즉, 1)판단기준을 평가할 때는 정규 AHP 과정을 사용하고, 2)대안을 비교평가 할 때는 다속성효용모형(multi-attributive utility technique, MAUT)을 적용한다. 이 Hybrid 모형의 과정 감축효과를 이론적으로 도출하기 위하여 정보입력 횟수를 계산하는 산식을 만들었다. 그런 다음, 이 AHP-MAUT Hybrid 모형을 실제 분석 사례인 경기도 주민들이 분당-강남역 간 통근할 때 어떤 교통수단들을 선택하는지 분석하는 사례에 적용하였다. 그 결과 Hybrid 모형을 적용할 때 계산과정이 AHP 모형을 사용했을 때와 비교하여 42.03% 감소하였다. 그리고 Hybrid model을 적용한 주민들의 선택 결과와 표준 AHP를 이용한 주민들의 선택 결과를 서로 비교하였다. 혼동모형에서 도출한 두 모형 간의 선택 일치도(CA)는 82.1%로서, 상당한 정도로 일관성이 있다 할 수 있을 정도였다. 결론적으로 본 연구가 목적하는 바는 AHP보다 간단하고, 편리하면서도 동등하게 효과적인 의사결정지원시스템을 개발하는 것인데, AHP-MAUT Hybrid 모형이 그 목적에 부합하였다. 이런 결과에 힘입어 Hybrid 모형의 적용사례가 증가한다면, 그것이 표준 AHP의 대안 중 하나로 고려될 수 있다는 점이 본 연구의 기여이다.

Objective : This is to report the criteria of success of intraoral distraction osteogenesis for alveolar augmentation in the severely atrophied alveolar defects through clinical result of 2 cases. Subjects and Methods : Anterior segmental osteotomy was performed and alveolar distractors (Martin and Leibinger, Germany) were applied each in 2 patients with severely defected anterior maxillary area. The osteomized alveolar segments were distracted by 1mm a day after latency period. After the consolidation period implants were installed with removal of distractor. The implants were evaluated clinically and radiographically. Results : In Case I, the distracted bone was directed to the palatal side, and another augmentation treatment - block bone graft, guided bone regeneration - was needed. In Case II, the successful alveolar bone augmentation was achieved. Dental implant was placed on distracted alveolar bone, and showed good osseointegration and good function without any complication. Conclusion : Distraction osteogenesis can be a good choice for alveolar ridge augmentation of severely atrophied ridges. However, the anterior esthetic prosthetics relies on the control of the vector, the kind of distractor, the healing capacity of patient and the etiology of atrophy. Therefore another study of each category would be needed.

Statement of problem : Porcelain restorations are widely used in restorative dentistry with a high degree of general success. However, porcelain is brittle and may fracture intraorally. Sometimes a repair may be attempted using composite resin and bonding system available. Color stability of porcelain repair resins affects esthetics and prognosis of prosthesis, so that provides important criteria for the choice of porcelain repair resins. Purpose : The purpose of this study was to investigate the color stability of composite resins used widely as porcelain repair system. Materials and method : Composite resins used for this study were Carisma(Kulzer, Germany), Tetric ceram(Ivoclar, Liechtenstein), Filtek Z250(3M, USA), and Arabesk Top(VOCO, Germany). Thirty disc-shaped specimens($10{\times}2mm$) were fabricated from each composite resin. Color changes of specimens after treatment using thermocycling system(KD-TCS30, Kwang-duk F.A. Korea) and after immersion in methylene blue(0.05% by Wt) were measured with colorimeter(Model Tc-6Fx, Tokyo Denshoku Co.) and obtained data were analyzed. Results and Conclusion: The results obtained from this study were as fo11ows. 1. The color change of Filtek Z250 was lesser than those of Tetric ceram and Arabesk Top after thermocycling (12000 times). 2. All of the composite resins in this study showed increase of color change according to increase of thermocycling frequency. 3. After treatment with methylene blue, the color change of Arabesk Top was greater than those of Carisma and Tetric ceram, and Tetric ceram was more stable than others.
