This study is to know the Enhancement of Aviation Safety for Low Cost Carrier in Korea through the long and mid term air safety policy. Especially, the aviation safety authorities of the developed countries in aviation establish action plans under the system plan of central government. Then the countries implement those plans systematically to the related aviation business so that they promote efficient air safety policy implementation. At this time, the Korean government should present the vision about an air safety and systematic strategic plan to cope with the future aviation industry change. Also, it is needed to establish a specific aviation safety action plan. Namely, an air safety master plan and long-term road map must be established. This paper deduces some implications through the abroad cases of aviation safety plan, and then tries to find the applying method of the implications to Korea in the rapidly changing aviation market in the 21st century. It is expected that this paper will help the Korean aviation industry to play a major role in the future. In oder to get suggestions aviation policies of advanced countries with regard to aviation safety, we have looked at the aviation policies of the U.S., the U.K., Australia and Japan, and also LCC's states overseas, LCC's safety policies in Korea, and aviation safety status. Since existing LCCs and new LCCs based in Korea have become the new concept, this new market for LCC has been booming recently. Around Southeast Asia, while there are some LCCs including Air Asia which is supported by the government of Malaysia with emphasis on safety, there are other LCCs, which have failed to achieve confidence in safety and have led to aircraft accidents and financial mismanagement, so we need to verify the safety of overseas LCCs, try to improve domestic LCCs in order to fly international routes and aid international aviation safety. LCCs have been increasing lately thanks to open skies policy and a wide variety of flights.lines. Air Busan, Jin Air, Jeju air, Eastar Air are in service. so the risk of new potential hazards may increase. Therefore it is necessary to take the initiative in aviation markets inside and outside of Korea and the safety management of new LCCs should be taken more seriously than ever before. Among overseas aviation safety policies, we need to implement the FAA's Filght Plan which has a specific Business Plan. I hope this thesis will help improve aviation safety locally and internationally.

Nowadays, most of the hospital serves "one stop service" for CT scan. The patients could be taken the CT scan in the day they register for scan. On the contrary to the time convenience, patients are not satisfied with long waiting time and unkindness of staff. The objective of this study is to improve the patient's satisfaction for the CT scan, by analyzing inconvenience factors and improving the service qualities. From April 1 to August 30 in 2011, we investigated the satisfaction of patients who did examined abdomen CT scan with contrast media. We analyzed the 89 questionnaires before and after the service improvements from them. The worker's kindness, the environment of CT room and understanding about CT scan were answered by questionnaire and the waiting time of a day CT scan was drawn by medical information statistics. Also, the period before improvement was from April to June and the period after improvement was from July to September. And these questionnaire was analyzed through SPSS V. 15.0. In this study, kindness of staff, environment of CT room, intelligibility for CT scan and waiting time was explored and analyzed by SPSS V.15.0. The score of kindness was improved by 32%, satisfaction level of the environment was improved by 52.54%. The understanding level about CT scan was improved by 52.36% and the wating time of a day CT was shortened by 21% through our service enhancement programs. Consequentially, it is considered that these efforts would contribute to increase the revenue of hospital.

The purpose of this research was to evaluate the quality of take-out services at restaurants in Chungbuk Province. A questionnaire survey by 450 customers who had experience in take-out service at the restaurants was conducted and 378 completed questionnaires were available for statistical evaluation. Statistical analyses were made of raw data by SAS V8.2. The scale for analyzing the importance and performance of the service quality was composed of 5-point Likert scales. The main results of this study are as follow: The quality attributes of take-out service were rearranged into four factors in terms of food, sanitation, access and service. The importance score was higher than performance score. IPA showed that 'freshness of food material', 'cleanliness and hygiene in food', 'sanitation of facilities', 'neatness of employees' and 'price in food' was included in 'focus here' area. There was significantly positive correlation between factors such as food, sanitation, access, service and overall customer satisfaction (p<.001); between factors and repurchasing intentions (p<.001); and between customer satisfaction and repurchasing intentions (p<.001). According to multiple regression analysis, 26.27% of the variance in respondents' overall satisfaction score and 9.21% of the variance in respondents' repurchasing intention score could be explained by factors such as food, sanitation, access and service.

The world is preparing another unseen war, that is, the cultural war of digital economy which will dominate the new millenium. As the “contents”, which are composed of various ingredients of media, gain vitality, the developed nations are in preparation of the war with the “cultural industry” weapons. The digital economic experts say that the left out nations will become economic colony in the new millenium age. The most important characteristics of cultural industry is the unity of creativity and culture which is all the more improved on the basis of the culture created upon knowledge. This leads to competition between nations or regions, and to survive one has to develop the industrial structure through cognition of its own cultural value. Furthermore, it is not a short-term development and investment of cultural products but a study on the method to graft the cultural value to the industry itself. The multi-media period does not accept an independent medium, and the contents products are becoming the leading industry since il is proved that they last semi-permanently in the digital world. The victory lies in the quality and quantity of the contents as the high ability and variety of the technology of media advance in accordance to the market principles. Since the culture, science and economy are becoming one complex structure, all nations of the world are trying the evolve a unique design of their on culture on the basis of the global universality. In consequence, we should excavate a uniqueness from our cultural heritage and develop into a korean design which will be recognized in the world market. The value of our cultural property should not only be used as academic and research purposes but should be re-evaluated with modem view, recognized as the core element that decides the quality of life and developed into exclusive designs. The korean designs represent the mould concept of our people which evolves from the mould or shape alphabet of Korea To meet the requirements of the changing world and in preparation of the cultural competitive age, it is never too early to make a data on the korean designs through their analysis and evaluation.

Packages have been used for a wide variety of purposes, for protection, for display, for transportation of goods, or for keeping personal belongings. According to the demands of society and the times, liquor packages have been specialized and have appeared in almost every shape and size without restriction to cine particular type of material. In spite of its rapid development and wide application in our society, liquor package design has rarely been considered as a subject of comprehensive study. Majoring in package design, I have become especially interested in the area of liquor package design. I would like to explore liquor package design from several aspects. With the advent of new market and the rise of a new consumer society, advertising and mass media have expanded rapidly. While convenience of use is not a major issue, serving size certainly are quality, appeal of heritage and health concerns. Heritage is a major consumer appeal in Whisky, Beer, Wine and spirits. Designers have drawn heavily on the tradition of alcoholic products, have used type and graphics to create the illusion of heritage for new products. A sidelight to the heritage aspect of spirits package is the evolution of outer boxes for international liquors. International liquors package design illustrated the past and current themes. The design is contemporary and spare. Colored panels correlated to the liquor flavor used on clean white, black, gold boxes. While this research does not deny the impact of structural innovation and convenience package design , it does deny the existence of a graphic plateau. It is assumed therefore, that development in technology can facilitate communication between East and West. This can be accomplished because as containers of products are used in social setting, their form will gradually apply strong influence to the need for economical, easily handled, easily utilized packaging. Typically, ethnic package designs are those packages containing products which are prepared and marketed to a category of people who are prepared and marketed to a culture traits. They are liquor products sold in the metropolitan New York area which are marketed specially to Asians, Hispanics, or Eurpean population. These cultural groups share numerous traits including religion, language, dietary habits and traditional drinking styles. Therefore, the products which are familiar or common in their native countries are often imported or marketed there to serve them. These packages and products are frequently found on the shelves of supermarkets in predominantly ethnic areas. That is Korea, Japan if packaging is correctly design it would appeal to the American market. My research is that oriental beverage -Soju is good example of this precept. Assumedly, there must be a degree of subjectivity since it is a mean in which the consumers can relate to its advertising. This degree to relate and identify is the degree to which the package will be remembered and purchased. Subjectivity is intimately related to purchases since there is no such thing as a rational purchase in a society that operates on mass consumption. It is essential that packages become more personal human, entertaining, and more like advertising in order to maximize merchandising potential.

The objective of this study is to improve the efficiency of embryo transfer in generation of transgenic mice using inbred mouse (C57BL/6J) embryos. The embryos of C57BL/6J and BCF1 mice were superovulated by the standard protocol. One-cell stage of embryos were microinjected and the resulted one-or two-cell were transferred into one-or two-side oviducts of foster mother, respectively. When one-cell stage of embryos were transferred into one-side oviduct of 0.75 d.p.c. foster mother, the results were not ideal because of showing pregnancy ratios of 68.8$\pm$7.83% for C57BL/6J and 48.3$\pm$14.22% for BCF1, and development ratios of pups vs transferred embryos of 11.9$\pm$5.51% for C57BL/6J and 10.5$\pm$8.03% fur BCF1 . However, when two-cell stage of embryos were transferred into two-side oviducts of 0.5 d.p.c. foster mother, we got better results of 94.4$\pm$9.64% and 100$\pm$0% pregnancy ratio, and 22.1$\pm$0.4% and 21.8$\pm$0.38% development ratio for C57BL/6J and BCF1, respectively. Therefore, transferring two-cell stage of C57BL/6J embryos into two-side oviducts of 0.5 d.p.c. foster mother may be competitive to the result in BCF1 embryos. Even if there are a lot of other factors affecting these results, we conclude from these experiments that transfer of two-cell embryos into two-side oviducts of 0.5 d.p.c. foster mother is a more efficient and safe method than others in generating transgenic mice using inbred mice embryos.

To evaluate the primary production and nutrient uptake of macrophytes in Lake Paldang, this study investigate the vegetation areas of six dominant aquatic plants including Typha angustifolia, Zizania latifolia, Phragmites australis, Trapa japonica, Nelumbo nucifera and Savinia natans, and contents of carbon, nitrogen and phosphorus of each macrophyte. Total vegetation area of six dominant aquatic plants was 1.37 $km^2$. Among them, Typha angustifolia was the most wide-distributed species which occupied the 46.7% of total vegetation area. Littoral zone of South Han river had the largest vegetation area with 0.458 $km^2$, and North Han river, Kyungan river and confluence area in the order named. The results of the contents of carbon, nitrogen and phosphorus of macrophytes showed that the carbon contents of emergent macrophytes was higher than that of other life-forms. The nitrogen content of Salvinia natans, free-floating macrophyte was highest and that of Typha angustifolia, emergent macrophyte was lowest. The phosphorus content of Trapa japonica showed the highest content of phosphorus among six macrophytes and emergent macrophytes such as Zizania latifolia and Phragmites australis showed lower contents of phosphorus than other life-forms. The annual net primary production of macrophytes in Lake Paldang, 2004, was calculated as 758.4 ton C $yr^{-1}$ and the annual net nitrogen and phosphorus uptake of macrophyte was 16,921 kg $yr^{-1}$ and 1,841.0 kg P $yr^{-1}$ respectively. Comparing the total budget of organic carbon, nitrogen and phosphorus in Lake Paldang, the amount of primary production and nutrient uptake by macrophytes take a small portion in total budget implying macrophytes do not play an important role in budget of matters in river-type lake, Lake Paldang.

To evaluate the degree of contamination caused by oil spill accident in the sea, the in-situ sensors which are based on the scientific method are needed in the real site. The sensors which are based on the fluorescence detection theory can provide the useful data, such as the concentration of oil. However these kinds of sensors commonly are composed of the ultraviolet (UV) light source such as UV mercury lamp, the multiple excitation/emission filters and the optical sensor which is mainly photomultiplier tube (PMT) type. Therefore, the size of the total sensing platform is large not suitable to be handled in the oil spill field and also the total price of it is extremely expensive. To overcome these drawbacks, we designed the fluorimeter for the oil spill detection which has compact size and cost effectiveness. Before the detail design process, we conducted the experiments to measure the excitation and emission spectrum of oils using five different kinds of crude oils and three different kinds of processed oils. And the fluorescence spectrometer were used to analyze the excitation and emission spectrum of oil samples. We have compared the spectrum results and drawn the each common spectrum regions of excitation and emission. In the experiments, we can see that the average gap between maximum excitation and emission peak wavelengths is near 50 nm for the every case. In the experiment which were fixed by the excitation wavelength of 365 nm and 405 nm, we can find out that the intensity of emission was weaker than that of 280 nm and 325 nm. So, if the light sources having the wavelength of 365 nm or 405 nm are used in the design process of fluorimeter, the optical sensor needs to have the sensitivity which can cover the weak light intensity. Through the results which were derived by the experiment, we can define the important factors which can be useful to select the effective wavelengths of light source, photo detector and filters.

As China continues to evolve as a major economic power and the Free Trade Agreement (FTA) between the Republic of Korea and China was ratified on June 1, 2015, market volume between the two countries is expected to grow more rapidly. This study aims on improving the efficiency of car-ferry lines. We conducted two surveys- for shippers and forwarders of car-ferry companies, and container liners. The study analyzes the decision factors for delivery companies and their importance for shippers and forwarders of car-ferry companies and container liners. Based on analysis of prior studies on the competition for car-ferry companies and liners, three primary variables are selected-promptness, economics, and safety. The promptness variable consists of shipping time, loading/unloading time, and customs clearing time. The economic variable consists of marine transportation cost from a domestic harbor to China, loading/unloading cost in the harbor, and overland transport cost from the harbor to shippers inland. Finally, the safety variable consists of cargo damage rates, safety facilities, such as lashing and shoring, and punctuality of transportation time. The survey and AHP results show that the promptness, safety, and economics factors are 0.549, 0.309, and 0.142 in the shipper groups of car-ferry companies' category, respectively. It indicates that there is considerable difference in the importance of each factor. In contrast, the factors are 0.350, 0.348, and 0.302 in the forwarders category, which suggests that there is little difference in each factor's importance. As for shippers and forwarders of liners, the importance of each factor is found to be in the following order: economics, safety, and promptness.

Tourism in the natural environment grows significantly and in many tropical countries it becomesthe important earning of the nations. Nevertheless, tourism impact to environment and cultural values has become the threats to the sustainability and competitiveness of such industry. Therefore, the appropriate planning and management of tourism destination sites where environmentally and culturally fragile are needed in order to increase economic benefits, sustain local culture and conserve environment in balance. The aims of the paper are to examine tourism practices, to determine socio-cultural and natural resources, and to assess local people perception to cultural landscape and its future tourism development in order to formulate the appropriate strategies to achieve sustainable tourism. A case study was carried out at Tengger highland, Bromo Tengger Semeru National Park(BTSNP) East Java. Official documents were gathered and interviews with several key persons had conducted to determine recent status of tourism, resources capital and the existence of local people. Semi-structured interviews and questionnaires were carried out at Tenggerese villages to explore local people perspectives to tourism development, culture preservation, and cultural landscape conservation issues. It is followed by descriptive analysis of vegetation to assess the recent status of environments based on vegetation information. Our findings reveals that tourism grows significantly at BTSNP, and Tengger Caldera as spiritual and cultural sites for local people become the centre for tourism activities. The abundance cultural and natural resources are the significant capital for sustainable tourism. Tenggerese argues that tourism should be planned to provide benefits to local people, preserve tradition and able to conserve nature in order to ensure the living sustainability of Tenggerese. The overall result of the study provide general feature of recent status of the cultural and natural resources as well as positive society perception in order to establish a strategy for sustainable tourism in cultural landscape.
