The KOMPSAT-3A is a high-resolution optical satellite launched in 2015 by Korea Aerospace Research Institute (KARI). KOMPSAT-3A provides Panchromatic (PAN-0.55 m), Multispectral (MS-2.2 m), and Mid-wavelength infrared (MIR_OR-5.5 m) image. However, due to security or military problems, MIR_OR image with 5.5m spatial resolution are provided down sampled at 33 m spatial resolution (MIR_rd). In this study, we propose spatial sharpening method to improve the spatial resolution of MIR_rd image (33 m) using virtual High Frequency (HF) image and optimal fusion factor. Using MS image and MIR_rd image, we generated virtual high resolution (5.5 m) MIR_OR^fus image and then compared them to actual high-resolution MIR_OR image. The test results show that the proposed method merges the spatial resolution of MS image and the spectral information of MIR_rd image efficiently.

Changes in food preferences and dietary habits of Korean prone to decrease consumption of the traditional energy source, rice. The exceeding condition of rice production in Korea is now not only impacting on the profit structure of farmers but also threatening food security. Although there have been several efforts to increase rice consumption rate, by developing various processed foods using rice flour, grain hardness of rice has been the most significant limiting factor. In this study, we addressed the suitability of the Namil(SA)-flo1, a mutant rice line has floury endosperm, in terms of producing rice flour by using dry-milling method, which is lower cost and more eco-friendly than other available methods such as wet-milling. Rice flour of the Namil(SA)-flo1 exhibited superior physico-chemical characteristics to any other check varieties including the wild type, Namil, in terms of distribution of granule sizes and content of damaged starch.

Cabotage means transportation of cargoes or passengers between two points within same country by vessel or aircraft which registered to foreign country. Cabotage regulation has justified by the protectionism in economic aspect and by national security in the defence of a country, thus most world's major countries including United States of America, Japan and European Union(outside EU) are executing cabotage. Even though Korean's controlled fleet ranked to 5th in the world, shortage and ageing of Korean domestic seafarers came to the restricted factor in the Korean domestic shipping. Resultingly Korean government permitted 530 Myanmarese and Indonesian seafarers to come on board in domestic vessel. In regarding to the Korean law, there are no direct relationship between boarding foreign crew in domestic vessel. However the baxic concept of cabotage will be spoiled by boarding foreign crew under the regulation of cabotage, so special treatment should be needed to cover the problems in coastal shipping arose form them. To minimize the problems derived from foreign crew, following actions are recommended; first, management skills of foreign crew are needed to overcome differences of communication and culture; second foreign crew supporting center should be established to counsel their difficulties; third, high level of manning companies should be promoted; forth, stabilized crew supply should be guaranteed by improving employment condition; finally, memorandum of understanding should be concluded between two countries to prevent seceders.

The purpose of this thesis is to do a research on suppression of peacetime international terrorism and penal system of terrorists by political and economic means. International terrorism means wanton killing, hostage taking, hijacking, extortion or torture committed or threatened to be comitted against the innocent civilian in peacetime for political motives or purposes provided that international element is involved therein. This research is limited to international terrorism of political purposes in peacetime, especially, hijacking of civil aircraft. Hijacking of civil aircraft include most of international terrorism element in its criminal act and is considered to be typical of international terrorism in view of multinationality of its crews, passengers and transnational borders involved in aircraft hijacking. Civil air transportation of today is a indispensable part of international substructure, as it help connect continuously social cultural and economic network of world community by dealing with massive and swift transportation of passengers and all kinds of goods. Current frequent hijacking of civil aircraft downgrade the safety and trust of air travel by mass slaughter of passengers and massdestruction of goods and endanger indispensable substructure of world community. Considering these facts, aircraft hijacking of today poses the most serious threat and impact on world community. Therefore, among other thing, legal, political, diplomatic and economic sanctions should be imposed on aircraft hijacking. To pursue an effective research on this thesis aircraft hijacking by six Chineses on 5th May, 1983, from mainland China to Seoul, Korea, is chosen as main theme and the Republic of Korea's legal, political and diplomatic dealing and settlement of this hijacking incident along with six hijackers is reviewed to find out legal, political diplomatic means of suppression and solution of international terrorism. Research is focused on Chinese aircraft hijacking, Korea-China diplomatic negotiation, Korea's legal diplomatic handling and settlement of Tak Chang In, mastermind of aircraft hijacking and responses and position of three countries, Korea, China and Taiwan to this case is thoroughly analyzed through reviewing such materials as news reportings and comments of local and international mass media, Korea-China Memorandum, statements of governments of Korea, China and Taiwan, verdicts of courts of Korea, prosecution papers and oral argument by the defendants and lawyers and three antiaircraft hijacking conventions of Hague, Tokyo and Montreal and all the other instruments of international treaties necessary for the research. By using above-mentioned first-hand meterials as yardsticks, legal and political character of Chinese aircraft hijacking is analyzed and reviewed and close cooperation among sovereign states based on spirit of solidarity and strict observance of international treaties such as Hague, Tokyo and Montreal Conventions is suggested as a solution and suppressive means of international terrorism. The most important and indispensable factor in combating terrorism is, not to speak, the decisive and constant resolution and all-out effort of every country and close cooperation among sovereign states based on "international law of cooperation."

The purpose of this study is to analyze the difference in suicide rates between regions and to determine the effect of social workers on the regional suicide rate. The main analysis results are as follows. First, the suicide rates in metropolitan cities were lower than was lower than in other regions, and cities and districts were lower than those in the county area. Second, suicide rates were high in areas with many cultural and social welfare facilities per population. Suicide rates were high in low mental health facilities and low social welfare budgets. The suicide rate in rural areas was high. Third, suicide rates were high in areas with low economic requirements, areas with a high proportion of the elderly, divorce rates, and areas with a small number of social security recipients and living alone. In other words, the suicide rate in rural areas was high. Finally, social workers did not affect the difference in local suicide rates. Local social services and budgets have no real impact on suicide rates. In the future, it is necessary to improve the quality and quantity of community welfare practices that can lower community suicide rates.
