Korea actively endeavors to improve the national marine environmental laws and regulations. Along with the growing global concern on the importance of marine environment, the concern is also increasing nationwide in Korea. These institutional changes in Korea have implications in that it has started to internalize the Sustainable Development Principle and the Precautionary Principle in the form of 'law' and 'policy.' The enactment efforts for conservation and sustainable use of marine environment will continue as the legal demand of public for coastal erosion prevention and climate change mitigation increases. This calls for robust revision for more logical framework and coherence of marine environment laws and regulations as well as efficient implementation of policies. In addition, it is strongly required that the systematical research and survey as well as the robust reversion of laws and policies should be taken accordingly for the effective conservation of marine environment.

Odor problem of livestock operation is important issue in a local community. I quantified the property price impact of 199 livestock operations for 3,355 housing sales in the U.S (Colorado). Spatial hedonic model was adopted to deal with spatial autocorrelation in housing market. Small beef and dairy operations, which are the traditional agricultural sector, seem to create a positive rural lifestyle amenity effect. However, the impact of livestock operation on rural residential sales turns to negative if the operation is over a certain size and species. Large hog and sheep operation seems to bring fatal economic loss from the local community perspective if it close to residential area. Livestock odor is one of the negative externality, the results provide the potential social cost of the livestock sector in the region. Policy makers may incorporate this social cost in the regional planning to minimize the social and maximize the development effect. Therefore, local officials and private individuals should carefully consider the location and characteristics of new residential properties and livestock operations alike.

The purpose of this study is to introduce the new regional geography approaches that have been lively discussed in English speaking countries since 1980s. The discussion of the new regional geography is based on intellectual interchange between geographers and social theorists. The new regional geographers regard a space as a more active thing. A space is not a merely passive container. It is not a outer settings, but a essential dimention of the human being. The new regional geography has been discussed in four perspectives: structuration theory perspective, spatial division of lavour theory perspective, world-systems theory perspective, and post-poststructuralism perspective. The new regional approaches well provide a new direction to regional studies. However, it is so abstracted in concepts for the empirical examinations that it is necessary to introduce a meso-level of concept.

In order to develop an effective antifungal antibiotics, over 700 isolates of bacteria, mold and actinomytes were screened from soil, and LAM 97-44 were selected as a strain producing the strong antifungal antibiotics against Candida albicans. Morphological, cultural and physiological characteristics of LAM 97-44 were investigated for the indentification. The cell size of LAM 97-44 was $2{\sim}3{\times}1{\sim}1.5\;{\mu}m$, and the shape of spore was of ellipsoidal. As a carbon source, LAM 97-44 utilized fructose, glucose, glycerol, maltose and raffinose but did not utilize arabinose, cellulose and xylose. The fatty acids of the cells included various iso-type and anteiso-type. Conclusively, the strain LAM 97-44 was proved to be Bacillus subtilis.

A mutant strain which hyperproduced thermostable ${\alpha}-amylase$ was obtained by chemical mutagenesis of Bacillus licheniformis. The mutant strain, SK-5, produced the enzyme about 50 times higher than the original strain. The mutant was longer and slimmer in shape, slower in growth compared to the original strain. Nucleotide sequence analysis of the SK-5 ${\alpha}-amylase$ gene revealed no changes in the the structural gene. The changes found in the promoter region might be responsible for the hyperproduction of the enzyme by the mutant. No structural changes in the enzyme structure could be observed when the secreted enzymes at various culture times were analyzed by Western blot.

The Secure Sockets Layer is a protocol for encryption TCP/IP traffic that provides confidentiality, authentication and data integrity. Also the SSL is intended to provide the widely applicable connection-oriented mechanism which is applicable for various application-layer, for Internet client/server communication security. SSL, designed by Netscape is supported by all clients' browsers and server supporting security services. Now the version of SSL is 3.0. The first official TLS vl.0 specification was released by IETF Transport Layer Security working group in January 1999. As the version of SSL has had upgraded, a lot of vulnerabilities were revealed. SSL and TLS generate the private key with parameters exchange method in handshake protocol, a lot of attacks may be caused on this exchange mechanism, also the same thing may be come about in record protocol. In this paper, we analyze SSL protocol, compare the difference between TLS and SSL protocol, and suggest what developers should pay attention to implementation.

The purpose of this study is to analyze current condition and features of female development funds of Busan primary local self-government, and to make useful implications out of this so that the local female development funds can contribute to its ultimate purpose, which is to achieve female development. The analyses show that 1) local self-governmental districts with good finance try to reserve funds by reducing programs; 2) local laws, which serve as the legal basis of female development fund utilization, do not reflect the value of gender equality; 3) the programs run by the female development funds lack contents; 4) beneficiaries of the fund programs aremixed; and 5) female policies and family policies are not separated, exhibiting the limitations of feministic perspectives. I propose that 1) the fund should be raised through the governance of local female groups and self-governments; 2) basic local laws should be revised: 3) gender perspective contents and birth support policy should be implemented.

The purpose of this study was to identify construct validity and reliability of instrument for professionalism in physical therapy using developed by American Physical Therapy Association for 470 physical therapists. The corrected data was analysed using confirmatory factor analysis and internal consistency. Model of professionalism was adequate (p<.05) and consisted of 7 factors. Standardized coefficients of construct factor were followed by the integrity (${\beta}$=.93), professional duty (${\beta}$=.92), and compassion/caring (${\beta}$=.86). There were significant difference in professionalism by career(p<.05) but not significant difference by sex(p>.05). Also, the internal consistency for sub-factor of professionalism demonstrated adequate reliability of the measure (Cronbach ${\alpha}$=.80~.96). Because instrument for professionalism in physical therapy have a validity and reliability, it is useful for measuring professionalism in physical therapists.

Landmines are a humanitarian challenge because they indiscriminately kill and maim civilians. Landmines are weapons that cannot distinguish between a soldier and a civilian, and they remain active for decades. As a result, most of the victims of mines are innocent men, women and children. For this purpose, new technologies such as a methode of landmine detection and mobile robots are needed. Our effort is to develop a small mobile robot for landmine detection, to detect landmine and to explore the landmine distinguishable method. In this paper, Specifically we detected landmines using electromagnetic sensors and distinguished metals from M14 antipersonnel mines under the ground using 6 step creativity of the TRIZ. Therefore, we proposed new method of landmine detection using the TRIZ.

Recently, China has expanded enormously its economic trade exchange bilaterally with other nations and developed as the second largest aviation market in the world. While open skies bilateral agreements were signed between China and other countries, the agreement processes influenced the aviation market structure and market sharing heavily. This paper analyzed the Chinese aviation market by such three angles as market scale, competitive situation, and market concentration. It is concluded that the Chinese aviation market is the oligopolistic market structure tested by the Herfindahl-Hirschman Index. Finally, suggestions are given to the airlines operating in China such as joining the air alliance, paying attention to a different frequent flyer program (FFP) etc.
