The Republic of Korea has achieved rapid growth in economic, cultural and social through the development policy over the past half-century. However, principle of the nodal system has made an overgrown city and underdeveloped regions. A range of policies have been introduced aimed at underdeveloped regions. But many problems were found in policies. Because government ministry and public services were many and various. In addition, development priority are not based on objective index, Distribution business for the local government have been carried out. A study of the Index selection of the existing regions, has been large-scale center analysis. Thus, the difficulty is often in selecting the priorities of small unit operations. It is difficult to reach a selection of business to region priorities. Accordingly I want to be used as material for the efficient development of rural areas through the selection of indicators for a small areas. Intend to use the decision support system for the efficient development of small underdeveloped areas through index selection for a small and underdeveloped regions.

In this study, we propose a rehabilitation protocol involving Korean medicine for patients after high tibial osteotomy (HTO) and report its effectiveness. Three patients underwent HTO using the rehabilitation protocol involving Korean medicine. We estimated the outcome evaluating physical examination findings of the knee joint, numeric rating scale, pain disability index, Lysholm knee score, and walking state. After the treatment, we observed that knee movement and muscular strength were improved. In addition, the numeric rating scale, pain disability index, Lysholm knee score, and walking state of patients were improved. Therefore, a rehabilitation protocol involving Korean medicine can be effectively used for patients after HTO. The limitation of this study was the insufficient number of cases and the difficulty of follow-up because of the characteristics of this operation and the long periods of time that are needed for each phase of the protocol. Further studies are needed to design a rehabilitation protocol involving Korean medicine.

The current housing performance rating system displays the performance rating of the houses supplied by the housing construction company, approved by the Housing Law. This system is intended to provide accurate information to the consumers in the announcement of the tenant recruitment, thereby improving the quality of the housing. This system was revised in January 2005 and implemented from January 2006. It is obligatory for companies with a scale of more than 1,000 households (energy performance rating is over 300 households), but there is currently no content on the waterproofing field. Therefore, this study suggests the revision plan proposes the necessity of the inclusion of the performance grade for the waterproofing field which is not currently implemented in the apartment house performance rating system, and to understand how to secure an adequate living environment. As a result, according to survey results, the performance score based on the difficulty of the maintenance method according to future leaks was selected and the revised system was prepared. Based on this, the performance grade for the virtual apartment was evaluated, and the results show that the performance of various grades is presented accordingly.

Predominant involvement of a particular group of fingers due to a central nervous system lesion has been described as pseudoperipheral palsy. Two patients visited our hospital with isolated weakness of a particular group of fingers due to small cortical infarctions. A 51-year-old woman suddenly developed weakness in her left index and middle fingers. The brain MRI showed a small infarct in the right frontal cortex. A 67-year-old man was sudden difficulty using his chopsticks and had weakness in his right thumb and index finger. The brain MRI showed a small infarct in the left precentral cortex.

This study has analyzed the efficiency of 10 leading global shipping companies listed in the New York Stock Exchange from2010 to 2014 in order to find the changes of the productivity of shipping industry. The paper observed the Malmquist Productivity Index by using Efficiency and Productivity Analysis System Version 1.0. The data used in this study is the Guggenheim Shipping ETF mainly including the companies of shipping, management, and shipbuilding areas. The results from this statistical analysis indicate that the 10 selected companies have experienced a severely negative growth in 2010. Nevertheless, these companies have accomplished a significant growth of productivity. In particular, the energy transport companies operating Tanker and LNG ships carried out remarkable growth. The reason why the productivity of liner shipping companies did not show the improvement of productivity for five years was attributed to the fact that the P3(Project 3) or M2(Maersk-MSC) including Maersk, MSC, and CMA-CGM were excluded in this research because of the difficulty of attaining reliable source data. The method of this study could be extended to Korean shipping corporations and other global airlines to investigate a changes of certain industries.

The purpose of this study is to develope and analyze a test for the assessment of physics inquiry experiment. To do this, three experiments about 'analysis of motion', 'the relation of force and acceleration', and 'free fall motion' in high school physics textbooks were chosen, and 5 scientific inquiry domains and 16 science process skills have been specified. For each experiments, test sheet of $29{\sim}44$ questions for assessing students' ability about physics inquiry experiment were developed on the basis of the scientific inquiry processes developed earlier. After instruction about 3 experiments mentioned above, a test was administered to the students who took experiment. After the adminstration of a test, the ratio of correct answers, discrimination index, and reliability were analyzed. Using the ratio of correct answers, we can determine item difficulty. Through the D.I(discrimination index), we can find which items can discriminate the students who took experiment well from those who took experiment badly, and we can also find the stability of a test result by the reliability analysis. The test developed in this study were also administered to the students who did not take experiments, and the results were compared with the those of the students who took experiments. With the comparison by chi-square method, we could find which items can discriminate the students who took experiments from those who did not take experiments.

In the design of underground excavation, the shear strength (SS) is a key characteristic. It describes the way the rock material resists the shear stress-induced deformations. In general, the measurement of the parameters related to rock shear strength is done through laboratory experiments, which are costly, damaging, and time-consuming. Add to this the difficulty of preparing core samples of acceptable quality, particularly in case of highly weathered and fractured rock. This study applies rock index test to the indirect measurement of the SS parameters of shale. For this aim, two efficient artificial intelligence methods, namely (1) adaptive neuro-fuzzy inference system (ANFIS) implemented by subtractive clustering method (SCM) and (2) support vector regression (SVR) optimized by Harmony Search (HS) algorithm, are proposed. Note that, it is the first work that predicts the SS parameters of shale through ANFIS-SCM and SVR-HS hybrid models. In modeling processes of ANFIS-SCM and SVR-HS, the results obtained from the rock index tests were set as inputs, while the SS parameters were set as outputs. By reviewing the obtained results, it was found that both ANFIS-SCM and SVR-HS models can provide acceptable predictions for interlocking and friction angle parameters, however, ANFIS-SCM showed a better generalization capability.

Random amplified Polymorphic DNA (RAPD) analysis Is based on the amplification of random DNA segment using a single arbitrary primer. Polymorphic DNA patterns identified by this method can be used for typing Listeria monocytogenes. To select the primers for RAPD typing Listeria spp., the performance of 31 primers were compared by analyzing 13 Listeria spp. reference strains. Reproducible electrophoresis patterns were obtained. Among 31 primers, 6 primers (primer 6, HLWL74, UBC155, UBC127, Lis5, Lis11) showed better differentiation, when discrimination index, band clarity, band number, difficulty of band scoring were considered than the others. These primers will be useful far typing Listeria spp. in the future. Currently, we are under investigation for the RAPD typing of contaminated L. monocytogenes for the risk analysis of pork processing plant using these primers.

Purpose: Many domestic companies have to make out quantitative evaluation table in their proposal when they conduct the software R&D project. However, most of companies have a difficulty to select the evaluation items and criteria, also to derive a quantitative results. Therefore, we propose a method to derive the quantitative evaluation index by utilizing the ISO/IEC 9126-2. Methods: Analyzing ISO/IEC 9126-2, and we classify the quality metrics as high-classification and sub-classification for Web/App software, Embedded software and Installation software. Next, Conduct the metrics selection survey depending on importance and necessity. Then, carry out the case study. Verify the correspondence between evaluation items and criteria from original suggestion of company and from outcome by utilizing the ISO/IEC 9126-2 quality metrics. Results: It is possible to classify into two metrics, one for common software or one another for only special software. Furthermore, there is quality metrics that is more important and more necessary depending upon characteristics of the software. Conclusion: ISO/IEC 9126-2 quality metrics can be used to make an evaluation items and criteria for quantitative evaluation table of software product.
