악안면 형성과정의 이상으로 인한 구조적 결함상태로 정의되어지는 악안면 기형(maxill-ofacial ogtal malformation)은 사고나 기능적(funct-ional) 장애로 인해 후천적으로 생길 수도 있으나 유전적 원인 등으로 인한 선천적 경우도 많다. 특히 후자의 경우에는 여러 증후군과 결합되어 나타나는 수가 많다. 치과의사는 치아이상이나 기능적 이상으로 인한 기형의 치료 및 예방을 담당할 책임이 있으며, 더욱이 새로운 진료실에서 직접 대면할 수 있는 최초의 의사가 될 수 있다는 점에서 특별한 기형외에도 전반적인 증후군에 대한 지식을 갖는 것이 중요하다. 악안면 기형환자에게는 전반적 검사가 필수적이며 방사선 분석, 치아모형 분석 등 다양한 분석이 필요하나, 여기에서는 주로 병력 청취나 시진을 통한 검사에 중점을 두어 서술하고자 한다.

It is well known that one of essential features of psychiatric disability is vocational impairment. Since the year of 2000 when psychiatric disability was declared as one of disability categories in Korea, vocational rehabilitation programs have been actively administered. At this point, it is compelling that vocational evaluation serves as a means of screening out the most promising candidates, identifying their vocational deficits and strengths, designing the individualized vocational interventions, and evaluating vocational outcomes. Still, vocational evaluation for people with psychiatric disabilities has been more problematic than for any other group with disabilities. The authors argued that vocational evaluation for people with psychiatric disabilities should be based on a certain vocational rehabilitation model to address those problems. It is because there exists an indispensible relationship between the vocational rehabilitation model and vocational evaluation. In other words, the main purposes, measurement time points, and focus of vocational evaluation may depend on which of vocational rehabilitation models to make a choice of. In addition, the vocational rehab model(i.e., vocational readiness model or graduation model) underlying traditional vocational evaluation does not seem to work for people with psychiatric disabilities. Authors argued that accelerating model fits for psychiathric characteristics which are often unpredictable and turbulent. As a preliminary step of developing vocational functioning instrument incorporating the demand characteristics of the accelerating model, post-hoc analyses were done on data from a vocational functioning measure and the results were critically examined from viewpoints of accelerating model. For these purposes, discussions were made about a) general functioning of vocational evaluation, (b) relation between vocational rehabilitation model and vocational evaluation, (c) the reasons why the accelerating model is more appropriate to the characterstics of psychiatric clients than the graduation model, (d) post-hoc analytic results reviewed from viewpoints of accelerating model-based vocational evaluation This study is significant in that it attempted model-based, model-specific vocational evaluation as a preliminary step for developing vocational functioning assessment instruments ill future.

In this study, we investigate the relative effectiveness of the two types of brand extensions (sequential extensions vs. direct extensions) in dissimilar extensions and examine the moderating role of two key variables - brand concept(functional brand vs. symbolic brand) and price of target extension product(low vs. high). The results from two experiments show that consumers evaluate the target extension product more favorably when brand is extended sequentially to dissimilar categories than when it is extended directly. However, the difference of target extension product evaluation between sequential extensions and direct extensions decrease when brand is symbolic and price of target extension product is high. Theoretical and managerial implications of the finding are discussed and inplications for future research are suggested.

Objective : The purpose of this study was to analyze the effects of simultaneous dual-task training to assess executive function in older adults. Methods : We searched the PubMed, EMBASE, Cochrane, Web of Science, and RISS databases of publicated studies in the past decade. Seven studies were selected based on the inclusion and exclusion criteria. Qualitative assessment and meta-analysis were performed for the seven studies. Results : A randomized controlled trial design was used in the selected studies, and PEDro Scores above seven were obtained. The Trial Making Test (TMT) evaluated the effects of dual-task training on executive function in four studies. The Color Trail Test (CTT) was used in two studies, and Stroop test was used in three studies. The effect size for total executive function was 0.38, which was small. The effect sizes for TMT and CTT were 0.37. Stroop Test was 0.34, demonstrating that their effect sizes were also small. Only significant effects in total executive function, TMT, and CTT showed significant effects (all p<0.05). Conclusion : This study confirmed that dual-task training was effective in improving executive function in older adults. To improve the effectiveness of dual-task training, the difficulty of the dual-task training should be considered. It is also necessary to implement assessments that can evaluate performance under dual-task conditions as well as conventional test tools for executive function. In the future, dual-task training could be used as an appropriate intervention for executive function in older adults to delay the onset of dementia.

This study aims to present an evaluation scheme to improve the problems in tree shapes and tree growth which were identified through shape and growth assessments of landscape trees currently planted in Haedoji Park, Songdo, Incheon Metropolitan City after plant structure status and propriety review for funtion of space and concept of planting. Suitability the planting concept was evaluated according to function of space. The result indicated that the shade planting areas accounted for 29.5% of the the shade spaces area. 58.7%, respectively planting areas of visual landscape. And 11.8%, respectively planting areas of buffer. Because the planting areas was lacked according to the park established spatial configuration of central facilities and the result of plant young trees. Plant structure status required consideration with plant structure, density, size, growth status for improve planting function. The tree assessment was performed on a total of 28 species and 600 trees of which 22 species and 209 trees were planted in the buffer zone, 8 species and 71 trees in the shade zone, 16 species and 266 trees in the visual landscape zone, and 4 species and 54 trees in the ecological landscape zone. The trees were divided into grades based on their assessment score and were statistically grouped by the functional zone in where they are planted and by tree species to verify their significance. The tree shape assessment was an average of 56.6 points and the tree growth assessment was an average of 76.0 points. Using the results of the tree assessments, the tree standards for each functional space were identified and a concept of optimum planting and cultivating was applied. When applying the shape assessment results by zone to the concept of planting, since trees for buffering require high functionality they received E's, the lowest grade; as trees for ecological landscaping require diverseness and naturalness, they received D's; since trees for shading require utilization, they received C's as trees with branching at the main stems were considered; and since trees for visual landscaping required aesthetical value, they received A's and B's. When applying the growth assessment results by zone to the concept of planting, based on planting foundations of favorable and poor, for buffering, visual landscaping, and ecological landscaping, trees from grades A to E could be planted, and for shading, trees from grades A to C could be planted. For a cultivation plan that could improve the growth of the trees, we proposed that the topography of the land be selected considering the tree's characteristics and that a method of pot seeding be used. Also, to improve the shape of the trees, we proposed that poles be used to improve the growth of vertically-straight stems, an appropriate planting density be applied for reasonable branch growth, manage tree shape to maintain good crowning, and better manage fertilization to maintain a reasonable crown density.

The study of ecosystem service assessment has been actively researched and developed from Millennium Ecosystem Assessment(MA) and The Economics of Ecosystems and Biodiversity(TEEB). However, current assessments are limited to monetary assessments of ecosystem function and do not account for the effects of environmental factors and socioeconomic status. This study proposes methods to evaluate ecosystem service based on environmental and socioeconomic factors. The study assesses water yield function through the water yield model in InVEST Tool, and evaluates the overall ecosystem service of water yield as reflected by the amount of precipitation and population of the area. Results show that a difference exists between spatial distributions of the ecosystem function of water yield derived from natural conditions such as land cover and soil, and the spatial distribution of the ecosystem service that accounts for climate and socioeconomic factors. The value of ecosystem service increases for an area of higher population and lower precipitation with similar water yield. Thus, the ecosystem service of water yield should be evaluated not only by the water yield function, but also by climate and socioeconomic factors. The evaluation process described for this study should also be applicable to the evaluation of ecological services in other sectors.

The purpose of this study is to propose the criteria for evaluating web information resources. This study also attempts to get a sense of the overall quality of web information resources and to identify the relationship among the criteria, Particularly those on the science and technology. Three evaluation categories are Proposed; information content functionality or workability, and design. Core features of information content includes authority, relevancy, currency; functionality includes navigation, user support technical requirements; layout and design includes visual appearance. Based on the proposed criteria, the 50 sample web resources selected from 5 different field were evaluated. The results showed that the web information resources on the Electrical and Electronic Engineering field was excellent. The Pearson's correlation coefficient between evaluation criteria showed that information content and functionality had a negative relationship, on the other hand functionality and design had a moderate correlation.
