Objectives : The purpose of this study was investigation of quality and quantity of nutritional intake related oral health status among Korean elders. Methods : The nutrient intake and the dietary quality was evaluated on the basis of the Dietary Reference Intakes For Koreans(KDRIs). Chi-square test for Complex Samples was used to determine the relationship between oral health and inadequate nutrient intake in Korean elders. The complex samples general linear model was used to test difference of average value difference of nutrient intake percentage compared to dietary reference intake(DRI), energy intake rate from three major nutrients, average mean adequacy ratio(MAR) and index of nutritional quality(INQ) related oral health status. Age, sex and total energy intake was compensated for this analysis. PASW 18 was used for statistical analysis. Results : We could found the difference of the nutrient intake and the dietary quality related oral health status among Korean elders. Especially, Nutrient intake percentage and component ratio of protein among energy intake rate from three major nutrient was lower as oral health status became worse. The percentage of subjects with nutritional intakes under showed highest level in worst oral health status. As oral health status became worse, average mean adequacy ratio(MAR) was lower and the number of nutrient of which index of nutritional quality(INQ) was under 1 was more. Conclusions : From the result above, this study clearly shows the level of oral health affecting the inequalities of eating and the food for the people. And the various propose of oral health policies is needed for vulnerable groups who needs solution to solve the problem of inequality of food distribution where intensive distribution of nutrition problem occurred. Sufficient, safe, and a variety of healthy food intake is a fundamental right of our people. And also, to apply this policy in reality, institutional arrangements and organizations, and specific performing system will be needed.

Rapid changes in the flora of exotic species are ecological problems that cause the alteration of national and regional biota. The purpose of this study is to identify the reality of neophyte flora currently inhabiting in Korea. Having analyzed a total of 151 studies published up until 2016, we found the qualitative and quantitative gaps among the preceding studies due to the lack of rigorousness on the application of the spatial and temporal level of exotic species and academic terminology. In this study, the neophyte is defined as the flora introduced temporarily after the Enlightenment in Korea (late 19th century) and spatially in the Eastern Asiatic Province of the Takhtajan's floral region instead of a country boundary. A total of 326 taxa of 184 genera of 39 families were identified and analyzed for their distributional origin and habitat characteristics. Approximately 87% (285 taxa) was a component of the single-layered herb vegetation, and a total of 211 taxa originated from Europe and North America which are the same temperate biome as Korea. The wetland vegetation components were much fewer with 21 taxa, but they included a large number of invasive alien species that caused critical deterioration in the habitat structure and function of aquatic ecosystems. Ecological approaches to exotic species categories such as Ephemerophyten and Apophyten have emerged.

The purpose of this study is to provide the visual landscape modelling on Josun royal tombs and surrounding. The visual landscape of traditional heritage is illustrated by the main view points of analysis. This analysis examines limited view points and cannot reflect a reality of environments. Nowadays various equipments and methodologies are developed for the visual landscape research. This study used new tools for analysis which are Sketch up (3D simulation) and mini helicopter (UAV). With those tools, this research examines not only view points of the analysis but also axis views and disincentive environments as a complex analysis. First of all, the research examined 3D modelling for the virtual simulation and drew coordinates and routes for the UAV operating. Secondly, UAV followed this routes and took linear and continuous views that are real scenes. As a result, it drew 3D simulation could illustrate and control the changing of environments such as the forest density and seasonal variations. Thus, comparing both of them shows efficiently landscape analysis. Thirdly, the study compared virtual and real landscape. Using this 3D modelling, this paper able to elaborate heritage environment and surrounding which omitted by view point analysis. Although this study has limitation practice and exercise on the field, the results and suggestions contribute to the various historic heritage managements and conservations. Moreover, it helps to explain the complex and dimensional landscape analysis.

The purpose of this study is to critically examine conventional spatial measures of individual accessibility, which are based on the notion of spatial proximity, the single reference location, and the unlinked travel model. Using space-time accessibility measures with the travel-activity diary data set of Portland Metro, US, three expectations from spatial measures on spatial patterns of individual accessibility were empirically examined: (1) does individual accessibility decrease with an increase of distance from the CBD?; (2) does the spatial pattern of accessibility resemble that of urban opportunity density pattern?; and (3) are spatial patterns of individual accessibility of different socio- demographic population groups basically similar as people in the same area share the same geographic characteristics regardless of gender, race, age, and so on? First of all, the results showed that spatial variations in individual accessibility were not directly determined by spatial proximity and opportunity density as suggested by previous accessibility measures. The spatial pattern of individual accessibility was dramatically different from that of urban opportunity density High peaks of accessibility level were found far away from the CBD and regional centers. This finding might be associated with the importance of multi-reference locations and linked travels in shaping accessibility in reality. Furthermore, this study found that spatial patterns of accessibility clearly differ between men and women. These findings suggest that access requires more than proximity, and that the interaction between person-specific space-time constraints and the consequential availability of urban opportunities in space-time renders different accessibility experiences to people even in the same region, which would be one of the key ingredients missing from conventional spatial measures of accessibility.

The purpose of this study was to look into Korean film criticism that started during Japanese occupation. It's specifically attempted to shed light on the development and significance of Joseon film criticism and on film movement theory as part of the history of Korean early modern film criticism. When kino-drama that could be called the start of Joseon movies was popular, enlightenment-based view of movie was rampant due to the inflow of western civilization and modernistic consciousness. Afterwards, the nature of movie itself drew a lot of attention from contemporary people in the silent picture days, and there appeared a critical trend in pursuit of artistry. Diverse criteria of criticism about reality and representation were presented, and a lot of disputes were eventually stirred up. Thus, criticism started to make a progress. A proletarian film movement theory, the so-called KAPF film campaign that was prevalent from the mid-1920s to the mid-1930s, was one of leading contemporary movie theories and took the lead in critic community. That had a great impact on the entire Joseon film circles. That took a proletarian view of movie, which was based on Bolshevik theory of Popularization and dialectic historical materialism. their criticism made a contribution to providing information on foreign movies and theories and to presenting main principles and multiple alternatives toward film organization and playing.

While the project for registering the unregistered relics that had been stored in the relic storage warehouse was in progress, restoration operations were started for the large size pottery pieces that had been excavated from the Geumgangsa Temple Site and it is attempted to explain the pottery pieces and to introduce the process of the overall conservation treatment. About 600 pieces of large size pottery had been separately stored in more than 40 relic boxes in their original damaged condition without making it possible to figure out their shape, size, usage and quantity at all. Due to the enormous number and weight of the pottery pieces, they were, first of all, pre-classified largely into 6 groups of pottery pieces in consideration of the visible features such as pottery thickness, color sense and glaze brilliance, etc. for each kind of pottery raw material. However, as a result of making them adhere together on a temporary basis, they turned out to be only one piece of pottery in reality. In this restoring process, in order to see if the generally used cyanoacrylate adhesive was in fact safe when a very large, heavy and deformed pottery piece was to be put together, its safeness was checked by examining the adhesion velocity, adhesion strength and dissolution velocity for both from low to high viscosities through preliminary experiments. In order to restore the lost parts after putting the existing pieces together, diversified epoxy resins were used to fit their shapes. Considering that the bottom of the restored relic was shaped to be not flat but round without allowing it to stand alone, an exhibition mount was manufactured so that the relic could be stored stably and used readily for exhibition.

We have to prepare for the existing threats from North Korea and potential threats in the future. It is important to utilize our resources as effectively as possible to build military power that brings victory in a war. Based on a sustainable required operational capability, weapons systems at the acquisition stage need to maintain a combat-readiness posture and ensure operational sustainability. To achieve this, establishment of procedures that develop elements of depot maintenance at the beginning, which enables economical and effective depot maintenance during that stage, is essential. First, the requirement paper needs to develop the concept of the depot maintenance requirement through the pre-study outlined by this paper. Second, at the system development stage, a Development Plan of Depot Maintenance draft should be proposed. This is the initial paper that can develop the elements of depot maintenance, and it should be verified by a field test. Third, each force's logistics command should write a Depot Maintenance Direction draft and a Mid-term Requirement of Elements of Depot Maintenance draft with the proven Development Plan of Depot Maintenance draft. Also, the verified paper needs to be realized and renewed by the time the Requirement of Elements of Depot Maintenance draft is completed. In conclusion, the procedures explained above will contribute to build an economical and effective military power in a reality faced with a resource shortage and threats from the enemy.

This paper analyzed the representation of migrants in television with the example of KBS's My Neighbor, Charles. This primetime TV show with consistent popularity has showcased different types of migrants from other Korean television shows in terms of gender and race, and, partly the difference brought popularity to it. This study finds the major reason of the difference from changed migration patterns in Korea. Until recently, the main population of immigrants in Korea was composed of female brides and workers, but it became diversified to include male and the West migrants. This triggered the changes in media representation, but not thoroughly. Though the faces of migrant protagonists have been diversified, the remaining ideology of nation-centric that has been the main frame to regard migrants as someone to be integrated through traditional values persists. This study finds a few conflicts between the traditional and the change. For example, represented realities of migrants are extends to include their activities in public domain, disputes of multicultural society such as social differentiation and bias, and the criticism of Korean traditional culture. In a gender perspective, while all the marriages represented showed different kinds of vulnerability, discourses of traditional familialism were also clearly presented through different tools of representation. This study aims at contributing existing studies of media representations of migrants with a more complicated pictures in the context of social changes and migration population changes.

The purpose of this study is to analyze the effect of policy in Jeju, using a macro-economic forecasting model of Jeju. First, the model's reality explanatory power improved by updating its statistics to 2017 and expanding new policy variables and modules. Also, the industrial structure of the model was further subdivided and extended to be considered simultaneously in the demand side of Keynesian theory. Second, it was determined that the predictive power for the model of this study was better than that of the existing model. However, with some endogenous variables, it was possible to identify implications that should be developed and considered when the model is improved with additional data in the future. Third, when the second airport construction was considered, it was observed that its effect was an increase of 1.25 times for GRDP, 1.2 times for employment, 1.48 times for private consumption, and 2.06 times for investment. Also, the economic growth rate was estimated to be 1.6% point higher than when the second airport was not constructed. Finally, the results of this study are expected to be used for policy decision making of the Jeju Government.
