The national level curriculum revision is underway in Korea. A proposed model of family and consumer sciences curriculum was proposed for a public hearing, which was held in December 15, 2005. In the model curriculum, practical problem focused curriculum development approach is partially adopted. However, there is lack of understanding for the practical problem focused curriculum, therefore correct understanding of it is needed. This study tried to promote understanding of the nature of perennial practical problem that FCS deals with and of a conceptual framework of practical problem focused curriculum development. Seven competing topics related with practical problem focused curriculum are discussed for resolving misunderstandings and prejudice on it. From the discussion, it is concluded that practical problem focused curriculum is meeting the needs of students' present and future individual and family life.

The purpose of this paper is to review the trend of research in geographical education since the launching of the Korean Geographical Society in 1945 and to suggest the areas and directions for future oriented research in geographical education. 422 articles (including 12 books) were reviewed and analized for this paper. The outputs of research in geographical education contributed in developing and improving the geographical education in primary and secondary school geography. But to achieve stable and desirable status as a subject in the school curriculum, research in geographical education has to be changed in its target areas and methods. The results and the suggestions of this study are summarized as follows: First, research in geographical education in diverse areas, especially in the areas of significance, aims and objectives, and psychology of geographical education should be preceded the revision of the school curriclum so that the results could be used as the basis information and evidences in decision making about the curriculum. Second, research in geographical education for affective domain and skill development should be implemented more actively in accordance to the trend of integration centering around the dicipline-inquiry skill and citizenship skill. More close relationship between the circles of geographical education and geography would be one of the ways to satisfy the social needs. Third, the linkage between primary and secondary school geography is crucial to the research in geographical education. Considering the sequence in human development research in geographical education for two levels of school should be conducted in more wide school-year span. Fourth, critical and prescriptive research in geographical education focusing on the individual, diciplinary, and social relevancy of the content of geographical education may be recommended. Finally, the outputs of the research in geographical education should be publicized more widely so that the rationale for justification of subject geography and geographical education may be shared with among the researchers, educational administrators, and practioners.

In recent years, computational models using parametric estimation method have been developed and used widely for efficient cost analysis. In this research, by applying experienced data from Guidance and Control Systems in Missile System field, the cost analysis for engineering model and commercial computational model(Price H, HL, M, S) are conducted and its result is analysed, so that the difference between two models and its grounds are apprehended. Comparing the calibrated value of computational model based on the data base of similar equipment and the cost from the engineering estimation, the two results are very close. It means that the credibility of data is enhanced through calibration. Also, for cost analysis of similar components in the future, the method for calibration of the computational models is also examined. When estimating development cost in this research, although many parts have been estimated through uncertain elements, the reliability could have been enhanced by applying computational model which secures objectivity. It is a very reasonable estimation method by utilizing calibration of the computational models based on existing accumulated development data.

Dentinogenesis imperfecta is an inheritable disease of dentinal defect, generally is inherited as a single autosomal dominant trait. It has a prevalence of 1 in 8000 with the trait, and no significant difference between male and female, with involvement of the primary and permanent teeth. Shields proposed three types of Dentinogenesis imperfecta. Affected teeth have various discoloration, separation of enamel rapid destruction of underlying dentin, and severe attrition. Radiographically, the teeth have cervical constriction, bulbous crown, thin root, obliteration of the root canals and pulp chambers, and periapical lesions in a sound tooth. The objective of treatment is rehabilitation of the esthetics, the masticatory function, and the vertical dimension of occlusion. In these cases, two pediatric patients reported to the Kyungpook University Pediatric clinic, with a chief complaint of discolored teeth and severe attrition. As a result of clinical and radiographic exam, it was diagnosed as Dentinogenesis imperfecta. The posterior teeth were restored with Stainless Steel Crown, and the anterior teeth were restored with composite resin veneering.

The growth characteristics of Pinus thunbergii windbreak forest around Goosipo Beach, Sangha-Myon, Gochang-Gun, Jeollabuk-Do have been investigated, and the results are summarized as follows. The soil in the site was light acid sand with pH 5.7, and the mean sodium concentration of soils was 1.42dS/m. The tree diameter, height, crown width, and shape ratio(Height/DBH) were better with tree density was coming lower. Especially, the rate of shape ratio under 60 was more in sites with low tree density. This demonstrated that the trees have grown more soundly when the tree density was lower. The direction of main winds and distribution ratio of tree inclination had a correlation. The inclined trees are seemed to be influenced by main winds when they were younger and by Typhoon partly. Eighty one vascular plant species were found in the sites, and more number of herbaceous plants (57 taxa) lived there than woody plants (24 taxa). And more plant species of dune were found at the site where dune have developed well. Some thinning works need at high tree density areas in order to ensure effects of coastal windbreak.

우리나라 조선산업이 21세기에 명실상부한 선진 조선국으로 발돋움하기 위해서는 단기적으로는 가격경쟁력의 강화가 요구되나 장기적으로는 기술자립화를 통해 과거 가격위주의 경쟁체제에서 기술위주의 경쟁체제로 전환함으로써 질적인 성장을 추구해야 할 것이다. 또한 우리나라의 조 선산업은 세계조선시장을 리드하는 선도국으로서 세계선박수급구조의 안정화에 노력하고 지구 해양환경보호를 위한 국제적인 프로그램에 적극 참여하는 한편, 후발조선국에 대한 기술협력, 기술지도 등 국제협력도 강화하여 명실상부한 선진조선국의 면모를 갖추어야 할 것이다. 이를 효과적으로 추진하기 위해서는 다음과 같은 과제를 해결해야 할 것이다. 첫째, 효율적 기술개발을 통한 건조기술의 재고가 그 무엇보다도 중요하다. 즉 단기적으로는 주요 대체수요 선박이면서 국내 주력건조선박인 탱커, 벌크케리어 등 재래단순형 선박에 대해 성에 너지화, 성인력화 및 표준선형화하고, 선박 생산공정의 개선, 생산성 향상을 통해 가격경쟁력을 지속적으로 확보해야할 것이다. 그러나 중장기적으로는 가스운반선,카페리선, 초고속선 등의 부가가치선박에 대한 건 조기술의 자립화로 이들 선종을 주력선종화하여 해외 수주 경쟁력을 재고시켜야 한다. 이와함께 심해탐사장비, 해양구조부유물 등의 해양개발장비의 개발로 사업영역을 확대해야할 것이다. 상 기의 각종 기술재발을 효율적으로 추진하기 위해서는 범국가적인 연구체제의 구성을 통한 산학연 공동연구형태로 추진하는 것이 바람직하다. 둘째, 핵심 조선기자재의 국산화와 품질 향상이 필 요하다. 향후 조선기자재의 국산화추진은 과거 개발 품목의 확대에서 벗어나 핵심적이고 부가 가치가 높은 품목 위주의 질적 국산화로 전환되어야 할 것이며, 이때 국산화이후 조선소의 적 극적인 구매가 전제되어야 할 것이다. 또한 기자재의 품질, 성능검사기능의 강화와 다수요 품목을 중심으로한 표준화, 규격화의 확대 추진으로 지속적인 품질향상과 원가절감을 도모해야한다. 특히 조선기자재업체의 영세상을 감안하여 조선소 인근지역에 단지화함으로써 생산설비의 현 대화, 자재의 공동구매, 물류비용의 절감 등을 기해 가격경쟁력을 강화해야 할 것이다. 또한 업계 공동의 해외판매망, A/S망의 직수출을 늘려야 할 것이다. 셋째, 국제협력 강화로 통상환경에 적극 대응해야 한다. 다자간조선협정 발효에 따른 제소 가능성에 대비하여 관민차원의 국제협 력을 강화하는 한편, 회계 기준의 통일, 제소사례의 연구 등을 업계 공동으로 추진하는 것이 바 람직하다. 또한 향후 2010년이후에 중국을 비롯한 후발조선국에 대해 조선협정에의 참여를 유도, 세계조선시장의 수급안정화에 노력해야할 것이다. 그외에 국제적으로 추진되는 지구그린화에 주도적 역할을 수행해야 할 것이다. 넷째, 선박금융제도의 개선과 신금융상품의 개발이 요구된다. 내수 수요인 계획조선의 지원조건을 개선하고 연불수출자금을 BBC자금으로 활용토록하여 국내 선주들의 신조를 유도해야 할 것이다. 그 외에 향후 금융개방화에 맞추어 해외자금을 활용한 리스금융, 상사금융 등의 민간신용제도를 더욱 활성화하고 선진국의 선박금융기법에 대한 연구 및 도입 등 선주들에게 다양한 선박건조자금을 제공하여 내수기반 확충에도 노력해야 할 것 이다.

Under the production system of a free market economy, the modern consumers'goods that feature current trends reveal diverse aspects of the whole society and culture. This phenomenon is progressing at such a rapid speed that theories can barely keep up to explain it dearly. It is believed that the reason for the lag in academic theories is the formation of pluralistic values in human lifestyles due to the development of science and information communication. The pluralism of values in contemporary society is being studied in many academic fields, and the design among these fields often sees such a phenomenon as one of the post-modernism concepts, where post-modernism suggests a diversification and dismantling of modernism. In other words, the current design is closely watching products that are totally different from existing products, from complex and conceptual outcomes in the field of design to products that reflect various trends. Thus, it is true that package design, which proactively reflects current trends, freely traverses among specific domains of various fields that have been determined tacitly. It is also believed that other fields are also reflecting the same developments. Such a phenomenon is strikingly revealed with so-called 'fancy products', while other products 'parody' package design. This study sees the phenomenon as dismantling the border between product design and package design. The examined package design reflects the broader characteristics of the times, based on current concepts and meanings, after reviewing design examples.

Levels of ethyl carbamate, a potential carcinogen produced naturally during fermentation, in major Korean fermented foods and some selected alcoholic beverages were determined by GC/MS/SIM, and their average daily intake and excess cancer risk of Korean people were estimated. In GC/MS/SIM analysis average 1.41, 19.44, 3.00 and 170.88 ${\mu}$g/kg of ethyl carbamates were detected in Baechu kimchi, Japanese soy sauces, Soju and fruit brandy, respectively. The average and maximum daily exposures to ethyl carbamate through major Korean fermented foods and alcoholic beverage consumption were 9.42 and 35.75 ng/kg bw/day for Korean female aged 20-64 years, and 12.73 and 48.87 ng/kg bw/day for Korean male respectively, which were mainly contributed by Baechu kimchi, Japanese soy sauces, Soju and fruit brandy. The average and maximum excess cancer risks were $4.7{\times}10^{-7}$ and $1.8{\times}10^{-6}$ for Korean female, and $6.4{\times}10^{-7}$ and $2.4{\times}10^{-6}$ for Korean male. Therefore, the industries related to fermented foods and alcoholic beverages need to make an effort to reduce the amount of ethyl carbamate in their products.
