Numerical analysis for slamming impact phenomena has been carried out when 2-dimensional wedge shaped structure with finite deadrise angles enter the free surface by using a commertial CFD code, FLUENT. Fluid is assumed incompressible and entry speed of the structure is kept constant. Geo-reconstruct scheme (or PLIC-VOF scheme) is used for the tracking of the deforming free surface. User defined function of 6 degrees of freedom motion and moving dynamic mesh option are used for the expression of the downward motion of the structure and deforming of unstructured meshes adjacent to the structure. The magnitude and the location of impact pressure and the total drag force which is the summation of pressures distributed at the bottom of the structure are analyzed. Results of the analysis show good agreement with the results of similarity solution, asymptotic solution and the solution of BEM.

This paper attempts to account for the recent decline in the share of 'regular employees' among total employees. It finds, among other things, that the decline which began in 1993 is not associated with the changes in the composition of the worker groups that have differing tendency to work as regular employees. Overall, the decline in the share of regular employment is mainly due to the workers' increased transition probability out of 'regular employment', with the exception of the younger workers for whom the decrease in the rate of entry into 'regular employment' has also been an important reason of such a decline.

This study was purposed to analyse the registration of Korean Fashion brands in China and to point out problems by the registration of analogous trademarks to Korean brand names. List of total 137 Korean national brands were used to collect trademarks in Chinese Trademark Office and each trademark was analysed by the nationally and the date of registration. Analogy of registered trademarks were classified by the common traits. In Result, only 61 Korean national brands were registered by Korean fashion firms in China and 37 Korean national brands were registered by Chinese firms or individuals in the same product classification or in the similar fashion product classification. And 22 Korean national brands out of 61 registered by Korean firms were also registered by Chinese firms, which may lead confusion and misidentification to Chinese consumers. Pre-registration by the Chinese firms f9r analogous or identical trademarks of the Korean fashion brand names in analogous product classification should be a serious entry barrier to Chinese market.

The aim of the work described in this paper is to develope a constitutive model for the prediction of an unsaturated clayey soil and to confirm the application of the model. To this end a series of suction controlled isotropic and triaxial compression tests are conducted on clayey soils. Matric suction is controlled by the axis translation technique using high air entry ceramic disk. Total volume change, air and water volume changes are measured by the device made for the experiment. The specimens are compacted by dynamic compaction using a half of Proctor compaction energy with the water contents of 5% drier than the optimum moisture contents. From test results, volume changes and deviator stresses are analyzed at each state and their relationships are formulated. And the application of the model to clayey soils is confirmed by the comparison between test and predicted results. During drying-wetting and loading-unloading processes for isotropic states, the agreement between predicted and test results are satisfactory. And predicted deviator stresses are well agreed with the test results in shearing process, but volumetric strain is not well agreed with the test results in high suctions.

The purpose of this study is to survey input data error of ship automatic identification system (AIS) and suggest its improvement. The effects of AIS were observed. Input data error of AIS was investigated by dividing it into dynamic data, static data by targeting actual ships and its improvement method was suggested. The findings are as follows. Looking into accidents before and after AIS is enforced to install on the ship, total collision were decreased after AIS installed. Static data error of AIS took place mainly in the case that ship name, call sign, MMSI, IMO number, ship type, location of antenna (ship length and width) were wrongly input or those data were not input initially. Dynamic data error of AIS was represented by input error of ship's heading. As errors of voyage related data take place as well, confusion is made in sailing or ship condition. Counter measures against the above are as follows. First, reliability of AIS data information should be improved. Second, incessant concern and management should be made on the navigation officers.

Purpose : The purpose of this study was to investigate the coincidence between keywords of Journal of the Korean Society of Physical Medicine (JKSPM) and MeSH terms, a controlled vocabulary used in MEDLINE. Methods : A total of 838 keywords used in 252 papers of JKSPM from Vol.1, No.1, 2006 to Vol.7, No.1, 2012 were compared with MeSH terms. All of keywords are classified to three large categories; complete coincidence, incomplete coincidence, and complete incoincidence. Results : The keywords in complete coincidence category were 183(21.8%), the keywords in incomplete coincidence category were 378(45.1%), and the keywords in complete incoincidence category were 277(33%). The most used keyword in complete coincidence category was 'stroke' and in complete incoincidence category was 'balance'. The most used keyword matching entry terms in incomplete coincidence category was 'elderly'. Conclusion : The rate of complete coincidene of keywords with MeSH terms was not higher than the rates of incomplete coincidence and complete incoincidence. It is necessary to understand MeSH terms more accurately and specifically. The JKSPM should ask the authors to use MeSH terms as keyword when they submit the paper.

The purpose of this study is to analyze the scale of overseas design orders in Korea, China and Japan by region and type of work, and to draw implications. As a result of analyzing the overseas design sales market of Korea, China and Japan, all three countries have the highest percentage of overseas sales in the Asian market, and the overseas design sales are the highest in power generation, chemical plant and transportation sectors. In addition to the Middle East and Asian markets, Japan and China have also diversified their strategies to diversify their markets by taking orders in various regions such as Europe, Africa and the United States. In particular, China is promoting the "New Silk Road Project" (One belt, One road), linking land and sea to a total of 25 countries and actively supporting aid projects in Africa and Asia, have. In addition, Japan has been actively supporting the government's expansion of ODA projects to expand overseas market entry. Therefore, it is necessary for Korea to increase its market share through diversification of overseas design market and diversification of industrial type, and to participate in overseas design market by expanding customized R&D investment.

Objective: The purpose of the study was to analyze the difference in the importance and performance of the educational content of the community pharmacy practice and find the factors that influence it. Methods: A 5-point Likert scale questionnaire asked about the importance and performance of the pharmacy practice education items to community pharmacy preceptors, current students, and professors. Data were analyzed using Microsoft office 365 Excel and IBM SPSS 21.0. Results: A total of 117 people participated. The averages of importance and performance were 4.34±0.34 and 3.71±0.45, respectively. Except for the computational entry of prescriptions and medication history, the average score for the importance of all educational items was statistically significantly higher than the one for performance. Importance Performance Analysis (IPA) identified over-the-counter medication counseling, over-the-counter drug selection consultation, pharmacy management, adverse drug reaction monitoring, and understanding and implementation of drug use evaluation as the items that needed focused effort. Borich's needs were highest in the adverse drug reaction monitoring. Conclusions: Overall, high importance and low performance indicate a need for improvement in community pharmacy practice education. Since the demand for education was high in over-the-counter medication counseling, adverse drug reaction monitoring, and OTC drug selection consultation, various supports are urgently needed to strengthen pharmacy practice education in this area in the future.
