Water Management Resilience Index (WMRI) was developed as a policy measure of adaptability to withstand water stresses and to set up water management strategies mainly in mid-small scale tributaries, and then evaluated on 117 sub-basins in South Korea. The index consists of 3 sub-indices such as vulnerability, robustness and redundancy sub-indices, each including indicators of 3 sectors: water use, flood mitigation, and river environment. Total number of indicators selected for the index was 31. Taking into account the stream order and control capability of river flow discharge, sub-basins were categorized into 3: 1 for mainstreams of lower large dams, 2 and 3 for tributaries, respectively without and with flow discharge regulation. As a result of the evaluation, resilience index scores in Category 2 and 3 are much lower than that of Category 1, especially with very poor score of redundancy. Although there was no significant difference between mainstream and tributaries in vulnerability and robustness sub-indices, results of redundancy sub-index in tributaries were lower than those in mainstream. Thus, it is conceived that the variety of water management schemes should be considered to improve their resilience in the face of future uncertainty. Addressing comprehensive stability of river basin against internal and external impacts, WMRI in this study can also be used for the prioritization of water management plans.

In this thesis, a new measurement system is implemented for depth data extraction based on the camera calibration of the known pattern. The relation between 3D world coordinate and 2D image coordinate is analyzed. A new camera calibration algorithm is established from the analysis and then, the internal variables and external variables of the CCD camera are obtained. Suppose that the measurement plane is horizontal plane, from the 2D plane equation and coordinate transformation equation the approximation values corresponding minimum values using Newton-Rabbson method is obtained and they are stored into the look-up table for real time processing . A slit laser light is projected onto the object, and a 2D image obtained on the x-z plane in the measurement system. A 3D shape image can be obtained as the 2D (x-z)images are continuously acquired, during the object is moving to the y direction. The 3D shape images are displayed on computer monitor by use of OpenGL software. In a measuremental result, we found that the resolution of pixels have $\pm$ 1% of error in depth data. It seems that the error components are due to the vibration of mechanic and optical system. We expect that the measurement system need some of mechanic stability and precision optical system in order to improve the system.

The Korean construction industry has played a major role among all industries despite its relative small ratio of all. The global economic crisis, however, has adversely affected the construction industry. Therefore, the Korean government implemented a corporate restructuring process to ensure the stability of the financial market. The selection standard on workout enterprises by the government is based on two perspectives: (1) external factors, including macroeconomic indices and (2) internal factors, including financial statements of private enterprises. On the other hand, if considering the characteristics of the construction industry, a certain construction company may not be evaluated only by its financial statements. In other words, a valuation process that utilizes the financial statements only can be concluded to be irrational. Accordingly, this study aims to provide the valuation model, which embraces the characteristics of workout firms, and determines their implications. To accomplish this, each enterprise valuation was measured using DCF and Black Scholes models, and by comparing such results with their market value, each enterprise was determined to be either under or over-valued. The results of this study verified that the valuations of 2 workout companies (out of 4) showed a higher value than the market value.

The aim of this article is to analyze the relationship between the change of the diversity of the industrial structure, and regional employmentability and the intensification of regional competitiveness, and consequently, is to present policy implications. As a result of the analysis of the whole industry such as the primary, secondary and tertiary industry in Chungnam Province, the existing strategic implementation on the employmentability and regional competitiveness throughout the policy on the existing specialized industries can be regarded as appropriate. However, under the condition that danger and stability in each industry are fluctuated and the internal and external circumstances are varied, the detailed analysis and rapid policy prescription on the primary and tertiary industry are required. Along with these results, policy implications are as follows; Firstly, in terms of effectiveness, regional policy are simultaneously conducted along with industrial, technological and regional development's policies while consider ing complex and comprehensive characteristics of the regional industry and rapid changing the global market conditions. Secondly, with respect to equity, regional policy is needed to implement by reducing the socio-economic gap across regions and mixing regional and sectoral policies along with regional and local uniqueness.

The purpose of this study is to explore the necessity and possibility of establishing a research institute for local educational autonomy where the importance and necessity of institution establishment and operation are increasing with the decentralization and educational autonomy. The necessity of establishing a local educational autonomous research institute was examined in terms of both external and internal necessities, and the possibility of establishment in terms of the form of establishment, financial resources, and legal basis. In order to effectively cope with common issues by leading the nation's educational autonomy policy and legal agenda, and to support regional policy research and development by linking and cooperating with regional educational policy research institutes, local educational autonomous research institutes are established. This is an urgent point. Considering the publicity, professionalism, economic feasibility, and stability of specialized research institutes, the form of foundation corporation seems to be appropriate, and, like the case of specialized research institutes in general local autonomy, legal grounds for the establishment of special law should be prepared. In the future, it is necessary to conduct collaborative discussions and academic discussions with the Ministry of Education and the National Council for Superintendents of Education.

This study was undertaken to develop the optimum baking formular and process in making the improved soy-wheat composite breads furtified with soy flour, which has been known for a source of biologically active phytochemicals and for more vegetable proteins as well. The effects of the addition of soy flour on a rheological properties of dough, on the sensory characteristics of breads, and on the possibilities of commercialization of these functional breads were investigated. As the added amount of soy flour increased, water absorption, development time and the weakness value of dough were increased, but dough stability were decreased in the farinograph. In the extensograph, the more soy flour was added, the less the extensibility and the resistance to extention were shown. As the amount of soy flour increased, gelatinazation point was increased in the amylograph, but the maxium viscosity was decreased. As the added amount of soy flour was increased, b value(yellowness) was obviously increased, L value(lightness) was slightly decreased. However, a value(redness) was not nearly changed in the color of cut loaves. In sensory evaluation, the more soy flour was added, the less the external, the internal characteristics and the eating qualities were shown. Accorting to the addition of soy flour, the toughness and the brittleness tended to be increased proportionally. The dough of 10% soy-wheat composite flour(SF10) was the most favorable on the baking performance.

Quantitative rise and This study carried out qualitative research by utilizing NVivo 10 focusing on the contents of mass media such as newspaper or internet on the presidential security service up to the Park Geun-hye government from the 3rd Republic of Korea, which was established the presidential security service. The aim is to present opinion so that the presidential security organization can strengthen capability and function within the governmental organization down the road based on the contents of categories, which were elicited through this. First, there is a need of solidifying the internal stability with the expansion in the activity sphere of organization and of externally approaching the public with removing sense of difference caused by offering personal protection only to some of the privileged class in the meantime. Second, it is the foundation of a reason related to crime in a cause for Discharge by Authority pertinent to "law on security for president and others" in Article 10 in order to prevent a criminal act of having abused the task characteristic and the position superiority or an external pressure act related to intervention in rights. Third, there is a need of making it recognized as very important organization with putting differentiation from other organizations of the government by providing the disciplinary level more strictly than "disciplinary order on public officials" based on particularity and importance dubbed presidential security service along with correspondingly applying "disciplinary order on public officials" in Article 31 in accordance with "enforcement ordinance of law on security for president and others" in terms of service negligence and false-information report in relation to task performance.

This study investigated the effect of a 12-week rehabilitation program on the range of motion (ROM) and muscle strength of high school baseball players with shoulder instability. We allocated 12 players with shoulder instability to the rehabilitation group and 13 players without shoulder instability to the normal exercise group. Covariate analysis (ANCOVA) was performed to assess the ROM of the internal (IR) and external (ER) rotational joints before and after participating in the 12 weeks of rehabilitation, and two-way ANOVA was performed to assess isokinetic muscle strength. The statistical significance level was set at p<.05. The IR ROM of the dominant (D) shoulder with instability and non-dominant (ND) shoulder was significantly increased before and after the rehabilitation program. The total ROM of the D shoulder with instability significantly increased after rehabilitation. IR isokinetic strength significantly improved at an angular velocity of 180°/s after rehabilitation. These results indicate that the rehabilitation program used in this study could be effective in improving ROM and muscle strength in patients with shoulder instability. However, due to the limited results, additional research on the premise of extending the rehabilitation period is necessary.
