A network connectivity has been regarded as a key element to strengthen a business competitive power in the aviation industry, so many airport authorities try to attract the new airlines and scheme out new air routes. With this trend, a study for an induced travel demand estimation methodology is needed. This study introduces a demand estimation method, especially for a new air route to a promising destination. With the results of previous studies, the derived demand is classified into four types - Local, Beyond, Behind and Bridge. The explanatory variables are established for each type of demand and the main independent variables are composed of distance, ratio of detour, and relative capacity compared with other airports. The equations using such variables and statistically significant coefficients are suggested as the model to make an estimation of derived demand for a new route. Therefore this study will be expected to take an initial step for all related parties to be involved more deeply into developing new air routes to enhance network connectivity.

We can make the foundation of culture and contents solid with a mental altitude to make out and protect copyright. It'll be the basis of the cultivating student, the next generation in this field who are majoring in animation, comics and characters now. It will give them a good environment to learn more about copyright and motivate surroundings. With this kind of education, We can make and protect works better. This thesis is a result of study to show how to and when to instruct people copyright even though we have faced constant argument on copyright and new approach to the economic value of cultural contents which has been under industrialization. Also, another big issue is what class would be a good target of the education on copyright. College may be the last place in the regular course for education before starling his or her career. Thus, the education that is focused on the importance of copyright is recommendable at this time. Particularly, the students who are majoring carton, animation and character can keep a good attitude to protect copyrights for others through the timely education on copyright. What's more, we can build better environment for students who will start their career in the field of the cultural contents and copyrights because they will not only try protect copyrights for others but also they know their works will be protected through thls kind of education on copyright. I believe this kind of education in college will promote the development in the field of cultural contents and copyrights. Also, it will support social and economic development In culture after all.

Incheon international airport has tried to upgrade its image by hosting lots of international events and inviting celebrities as a honorary ambassador of airport. It is uncomparable to other airports all over the globe for incheon airport to utilize an honorary ambassador to promote airport. The purpose of this paper is to try to find out the PR effect of employing honorary embassador at Incheon airport, which has a positive impact on enhancing the image of Incheon airport. In other words, it should be considered the PR effect of honorary embassador has contributed to upgrading airport image resulting in the commitment of passengers. According to empirical research result, it is proven the attractiveness and trust of honorary embassador has not significantly positive impact on the airport's image. However it is also proven the PR activities of airport authority has a significant impact on the airport's image. Passengers believed the honorary ambassador has a high level of attractiveness and trust but they don't agree causal relationship among attractiveness, trust and airport image. That is, they are not interested in who is the honorary ambassador of airport but in the contents of airport's news article itself. The administrative implication is mentioned in the paper that airport authority should mainly focus on the contents of PR not the figure of the honorary ambassador.

This study was carried out to offer the systematical and scientific method of regional environment conservation by deciding the rank using fuzzy theory, and try to find the methodology to accurately accomplished the regional environment assessment for sound land conservation. The results were as follows. To transform the Likert's scale granted to assessment indicators into the type of triangular fuzzy number (a, b, c), there was conversion to each minimum (a), median (b), and maximum (c) in applying membership function. We used the center of gravity and eigenvalue leading to the rank. In the sequential analysis of rank-based test of assessment indicators by triangular fuzzy number, the result proclaimed that ranking of the indicators was, in the biotic field, in the order of 'dominance', 'sociality', 'coverage' and in the abiotic one, 'soil pH', 'T-N', 'soil property', and in the qualitative one, 'impact rating class', 'hemeroby degree', 'land use pattern', and in the functional one, 'protection of water resource', 'offer of recreation', 'protection of soil erosion'. Therefore, there was a difference between subjective rank from human and the rank from triangular fuzzy number. In other words, the scientific rank decision would be not so much being subjective and biased as dealing with human thoughts mathematically by triangular fuzzy number.

The wetlands have functions those were retention of diverse biota, purification of water quality, control of climate and flood, eco-tourism and supply of agricultural water, and that was the ecosystem of high biodiversity as the zone of transition between inland and water. Therefore, this study showed the conservation and management plan by analyzing in the abiotic and biotic environment of forest swamp, Gyeongsangbuk-do. The results were as follows. Examining the management plan of the abiotic environment, there will need to establish the hydrological plan in continuous expediting the supply of water to maintain a humid soil of swamp, and to try to find the organic farming, use of low toxic agrichemicals and so on to prevent occurring a non-point source pollutants. To prevent changing the flowing of ground water and inflow of earth and sand in modifying the land character, there will be needed to restrict the construction of farmland and slope around swamp. To manage the biotic environment, there needed to offer the habitat by removing the regular interval and individual of a dead tree, and to improve the growth environment of vegetation. Because the naturalized plants disturb the natural vegetation, they will be removed. The afforested trees like Robinia pseudoacacia and Amorpha truticosa will be renewed to prevent the heterogeneity of landscape ecology, and the active conservation plan on wetland species will be established. As this study was carried out to study on the partial swamp, Gyeongsanbuk-do, the ecological environments distributing a swamp in Korea show a some problem. In the future, the study will accomplish to study the accurately and objectively ecological environment and management of a swamp by analyzing the extensive sites.

If you compare recent works in small commercial places along with the terms such as Post-Modernism, Late-Modernism, and Dismantling, to those of 60's and 70's, you will discover for sure that recent works try to model individually with 'surface'. Expressing the responses to the multilateral cultural desires is available through the organization of surface, so are the re-presentationsof classic notions by adding decorations to the vertical walls, which are different from modern constructions that have persisted on only space itself as a main point. These trends are various organizing techniques with forms, decorations, materials, color etc. and made the surface modeling develop. What a 'surface element' means as a concrete notion in a design process in a commercial place is enormous. So, it implies lots of notions and logic, and can be a strong message-conveying means as well as an expressional language. At this point of view, the research was limited to Facade, which is treated as a creational object to a designer all the time in order to study what kind of system the surface organization has in a small commercial place. This is to find out what kind of system the designer uses to make the spatial images, orders and forms through surface, but ultimately it is to discover the designer's basic tecniques that he or she uses when planning. To sum up, we have studied the meanings of the composition and the changes of the organization of Facade to analyze the organizing techniques in Pasad in a small commercial construction which designers planned as material. We have also investigated the organizing techniques of surface by examining and analyzing the elements of Facade organizing techniques, i.e. its form, decoration, material, pattern and color.

Executing various constructions and national land planning, it has rised importance how to acquire 3-dimensional geographical information efficiently. In conjunction with this, the concerned parties are interested in the accuracy of GPS positioning and applications. This study suggest the efficiency and possibility to apply geographical information construction by kinematic GPS surveying as comparing kinematic GPS results with triangulation, trilateration and static GPS results. In this study, we try to compare static with kinematic and can determine 3-D positions with difference of 6 mm in distance, 2"/10,000-4"/10,000, 20 cm in latitude, longitude and height at local area. In addition, difference from conventional surveying is about 1"/l0,000-3"/10,000 in horizontal. Therefore it is expected to apply kinematic GPS to make out topographic map and to construct data base associated with GIS.associated with GIS.

Jeju where concentrates on agriculture and tourism, conversion of outdoor culture into cultivation under structure happens actively for the purpose of increasing profit so continuous examination on house cultivation area is very important for this region. This paper is to suggest the effective image classification method using high resolution satellite image to detect the greenhouse. We carried out classification of greenhouse using the supervised classification and rule-based classification method about Formosat-2 images. Connecting result of two classification try to find accuracy improvement for greenhouse detection. Results about each classification method were calculated the accuracy by comparing with the result of visual detection. As a result, mahalanobis distance among the supervised methods was resulted in the highest detection. Also, it could be checked that detection accuracy was improved by tying with result of supervised method and result of rule-based classification. Therefore, it was expected that effective detection of greenhouse would be feasible if henceforward further study is performed in the process of connecting supervised classification and rule-based classification.

The arguments exist that private health insurance(PHI) policy holders tend to use the health care services more than non-policy holders due to their little out-of-pocket spending, resulting in the adverse effects on the finances of National Health Insurance. This study aims to increase the objective understanding of the issue and to draw a direction of further research, by reviewing the articles, reports and statistics which examined the effects of purchasing PHI policies on health care utilization. Significant differences in healthcare utilization, except for the very partial increase of utilization in outpatient settings, have been not found. The similar trends of the results have existed in a few previous studies which tried to control the endogeneity of medical use and health insurance with latent variables which affect the decision on medical use and health insurance. However, we can not exclude the potential change of healthcare utilization patterns because the portion of the insured of indemnity PHI is becoming rapidly larger in the market. For further research, we should try to obtain the objective information of subjects' past medical history, health status, health related behavior, and income affecting purchase of PHI and utilization of healthcare services. And the efforts of controlling the endogeneity of medical use and health insurance with latent variables which affect the decision on medical use and health insurance, are very considerable.

This study was an investigation of obesity, food habits and daily nutrient intakes of the 4th grade elementary school students in daejeon. A total of 148 children(male:71, female:77) participated in the study. We classified the subjects into normal group and obese group according to the grade of obesity indices by body fat ratio(BFR), 70% of the male and 31% of the female were obese group. The average height, weight were $140.1{\pm}4.9cm$, $33.0{\pm}3.6kg$(obese group), $141.9{\pm}5.7cm$, $42.0{\pm}3.6kg$(normal group) for the male, $141.2{\pm}6.4cm$, $42.4{\pm}6.2kg$(obese group), $139.5{\pm}6.4cm$, $33.0{\pm}4.5kg$(normal group) for the female. Weight showed a noticeable increase in the obese group, but height was not statistically significant. In dietary habits, it wasn't statistically significant but male obese group showed statistically increase in terms of eating fast(p>0.05) and eating snacks before sleeping(p>0.01) and female obese group was higher in frequency of eating out a month than normal group. Energy intakes of obese group was more than normal group and the average intakes of Vit. A, folic acid, Ca, were below the RI. The average intakes of vit A, vit C, folic acid, Ca, were also below the RI in normal group. The average intakes of vit A, folic acid, Ca, Fe were below the RI in female. Especially in female the intake of Ca was only 53.6%(obese group), 56.4%(normal group) of RI. From these results, we knew prevalence of obesity in elementary school students were high and obese groups were high in energy intakes but low in essential nutrients. Therefore we have to try to prevent and treat childhood obesity. So nutrition education of balanced diet and good dietary habits is needed for elementary school students.
