Japan has abolished the 3 Principles on Arms Exports and announced the new 3 Principles on Transfer of Defense Equipment and Technology. This article investigates the backgrounds of the abolition of the old regulation on banning arms exports. Japan government repealed 3 principles on arms exports to develop military industry and they insist that they pursue their national strategy called "Proactive Contribution to Peace." The future changes in defense industry due to the new principles are examined with the analysis of the defense industry indicators. The home production of the arms could be continued. However the international cooperation for the co-development and co-production of the weapon systems would be increased with not only the US but also the various countries. At the same time the efforts to export arms overseas are anticipated to be enhanced by the Japanese government and defense companies.

In this study, land cover classification and NDVI evaluation for hazard mitigation precaution are carried out in surrounding areas of Yeongi-gun, Chungcheongnam-do ($132\;km^2$) where a project for multi-functional administrative city is promoted by government. Image acquired from KOMPSAT 2, LANDSAT and ASTER is utilized and comparative evaluation on limitation in classification based on resolution was carried out. The area mainly consists of arable land including mountains, rice fields, ordinary fields, etc thus special attention was paid to the classification of rice fields and ordinary fields. For the classification of image acquired from KOMPSAT 2, segmentation technique for classification of high-resolution image was applied. To evaluate the accuracy of the classification, field investigation was conducted to examine the sample and it was compared with the land usage and classification of land category in land ledger of Korea. Acquired results were made into theme map in shape file format and it would be of great help in decision making of policy for the future-oriented development plan of multi-functional administrative city.

Severe drought tends to occur in almost event five years in Korea. Drought responses have been well operated in close collaboration with the central, local government and the water management authorities on the institutional framework. However, the responses are usually post-activities to a drought event. The responses often face difficulties in operating and managing process due to an absence of a drought monitoring system and drought triggers. The objective of this study is to set up drought triggers through a time-spatial interpretation of drought index and the government responses during historical drought events. Drought triggers are divided into four categories: advisory, watch, warning and emergency stage. The range and drought-impacted area of an each stage in triggers have been addressed using drought index. Furthermore, a web-based drought monitoring system is illustrated.

This study analyzed valid samples of 707 units collected by conducting paper and online surveys on the Korean, the Chinese, the American, and the Japanese. The result showed that a significant causal relationship exists between power distance and pull motivation as well as collectivism and push motivation, which led to a conclusion that developing travel packages that can strengthen bonding of fraternal societies through various events and attractions is effective for respondents from Asian countries. On the other hand, Americans turned out to prefer practical plans, which could provide individual's needs and preferences, for example, a self-healing package. This study, using a simple survey, may have a limitation in that it does not allow the participants to express their opinions. However, the study is meaningful that it made a theoretical contribution utilizing Hofstede's cultural dimensions index, two types of motivation, and theories of customer satisfaction and revisit intention. It also has a practical implication in that it proposes the most optimal and applicable overseas travel marketing strategy by comparing cultural traits of each country.

This paper reports on a study testing a model that articulates factors affecting duration of the relationship between exporters and importers. The model posits that affective commitment and calculative commitment influence duration of the relationship. Affective commitment of an importer toward an exporter is hypothesized to be predicted by social satisfaction, which in turn may be predicted by cultural familiarity, perceived similarity, and credibility. In contrast, calculative commitment is hypothesized to be predicted by economic satisfaction, which in turn may be predicted by opportunism and relationship performance. A survey of importers was conducted to test the model. The study results provided support for most of the hypotheses. Theoretical and managerial implications of the study results are discussed too.

Unlike the traditional bricks-and-mortar marketplace, the online environment includes several distinct factors that influence Web site trust. As consumers become more savvy about the Internet, the author contends they will insist on doing business with web companies they trust. This study examines 1) how Web site trust is affected by the following web purchase-related factors: security, privacy, brand name, word-of-mouth, good online experience, and quality of information, and 2) how it influences outcomes. Unlike Urban and colleagues' study (2000), the author argues that not all e-trust bUilding programs guarantee success in building Web site trust. In addition to the mechanism depending on a program, building e-brand trust requires a systematic relationship between a consumer and a particular web site. The findings show that Web site trust does not build one or two components but are established by the interrelationships of complex components. By carefully investigating these variables in formulating marketing strategies, marketers can cultivate brand loyalty and gain a formidable competitive edge.

Despite a great performance of Korean online game in Chinese online game market, Korean companies were faced with decreasing market positions in China from 2006. To overcome this problem, I will suggest a research model about determinant of repurchase behavior of on-line game user and moderation effect of online review. Data collected from questionnaire survey were used in empirical analysis on research hypothesis through moderated multiple regression method. There are several conclusions as such; first, perceived value and loyalty of consumer have great positive relationships with repurchase behavior. Second, online review has positive direct influence on repurchase behavior and moderation effect of relationships among them. Third, game company has great efforts to develop online games and game contents which were guaranteed before in price, quality, information, and accurate consideration of online review.

An efficient screening method was developed for rapid selection of a few overproducers of itaconic acid (IA) among the great many mutants derived from mother strains of Aspergillus terreus. For this purpose, an attempt was made to reveal the relationships of the growth rate and sporulation of each mutant on PDA solid medium with its IA productivity in the final liquid production-culture. As a result, it was possible to classify the mutated strains into 5 groups (from [A] to [E] group) according to theirmorphologies (i.e., growth rate and sporulation extent) on the PDA slants. Notably, most of the high-yielding mutants of IA were observed to belong to [A]group which had the properties of the highest growth rate and sporulation among the 5 groups, whereas the mutant groups of [C], [D] and [E] with the contrasting morphological features showed significant reductions in their IA productivities. From these results, it was concluded that the probability of selecting IA overproducing mutants could be remarkably enhanced when the mutated colonies showing faster growth rates are firstly selected on the PDA plate, and then further screening process is performed on the basis of the sporulation extents of the mutants selected. Consequently, through the application of the strategy developed in this study, costs and time involvedin the labor-intensive task of strain improvement could be reduced to a great extent, because the time-consuming liquid culture processes did not need to performed for the unfavorable mutants belonging to the groups other than group [A].

This study looked over the laws and regulations related to forestry workers to analyze the safety accident rates for the past five years (2006-2010), and to suggest improvement plans to reduce the safety accident rates of forestry workers. Findings from comparing information obtained from data are outlined below. The safety accident rates had gradually increased in the forestry fields until 2010, but nowaday it is on the decline. Furthermore, the safety accident rates in the field of forestry were still serious compared to those in the other industrial fields as from 2.1 to 5.1 times. In the results, the workers were especially vulnerable to safety accidents when they fell under the following categories: when falling; within 29 to 90 days after starting the work; over 60 years old; less than one month of service; October; Wednesday; 11 a.m.; and the nether limbs of the body. In the case of Jeollabuk-do, it was reported that more than half of victims did not have any training in safety.

As a product of modern proof theory, linear logic is a new form of logic developed for the purpose of enhancing programming language by Professor Jean-Yves Girard of Marseille University (France) in 1987 by supplementing intuitionist logic in a sophisticated manner. Thus, linear logic' s connectives can be explained using information processing terms such as sequentiality and parallel computation. For instance, A${\otimes}$B shows two processes, A and B, carried out one after another. A&B is linked to an internal indeterminate, allowing an observer to select either A or B. A${\oplus}$B is an external indeterminate, and as such, an observer knows that either A or B holds true, but does not know which process will be true. A ${\wp}$ B signifies parallel computation of process A and process B; linear negative exhibits synchronization, that is, in order for the process A to be carried out, both A and $A^{\bot}$ have to be accomplished simultaneously. Since the field of linear logic is not very active in Korea at present, this paper deals only with syntax aspect of linear logic in order to arouse interest in the subject, leaving semantics and proof nets for future studies.
