The study began in recent years with the aim of grasping the nation's medical status following the fast-growing trend of international medical tourism and attracting foreign patients, among other things, Busan, which ranks second in attracting foreign patients after the nation's capital, Seoul, has been highly active in the past eight years, with foreign patients rising by about 426 percent, and Russian patients entering the sea. In addition, Gimhae and Changwon, the Busan-based Gyeongsangnam-do region, ranked first and second in number of foreign residents, and are inhabited by a variety of foreign workers. Medical institutions, such as hospitals, should be able to find directions within hospitals. It is also a space where information in various languages, including Korean, English, Chinese, or Russian, must be delivered in a single medium. Based on this research, the purpose of this research is to provide converged information that helps foreigners who are not familiar with Korean language easily understand the proposed recognition system when visiting hospitals. Therefore, this paper is applied to a multi-language survey of six medical institutions (A, B, C, D, E, F) at the university hospital in Busan, and 10 medical institutions (R, J) in Gimhae, South Gyeongsang Province with high foreign residents. Research results and contents are as follows. First, the results of analyzing the design of the sinusoidal system show that the font uses colorless Gothic fonts, arrows, and pictograms to introduce the design of a typical hospital sign system. Second, the results of the multi-lingual situation were found to have only two languages in the system, such as Korean and English, and to have four languages, including Korean, English, Chinese, and Russian, according to their geographical location. However, it was judged that most medical institutions currently have only two languages (Korean, English) that may cause some discomfort in terms of language for foreign patients in non-English speaking countries. Based on these findings, it is necessary to propose designs that are considered by Koreans as well as foreign users in the use of multilingual hospital sign systems.

The enforcement of the Nagoya Protocol, which regulates the acquisition and use of genetic sources, an essential material for biotechnology R&D, has imposed a burden for additional documentation works to researchers. In the past, countries regarded genetic resources as a common human heritage and thus allowed researchers to use them freely. However, they can no longer afford the luxury of such freedom now since many countries are introducing new laws and regulations on the acquisition and use of the resources as the Nagoya Protocol recognizes the exclusive ownership of genetic resources. Therefore, Korea, which is highly dependent on foreign genetic resources, needs a more systematic response. This paper aims to review the key contents of the Nagoya Protocol to raise awareness among domestic and foreign genetic resource users, including researchers of environment and ecology and present the overall structure, and flow of acquisition, access, and benefit sharing (ABS) for the use of foreign genetic resources to help them respond appropriately to the new landscape. The researchers' efforts and support at the national level are necessary at the same time to appropriately respond to the Nagoya Protocol. First, the researchers must understand the overall framework and the specific response in each stage under the Nagoya Protocol scheme. It is necessary to respond to the ABS procedure of the resource provider country from accessing genetic resources to sharing benefits resulting from it. In that regard, the Nagoya Protocol has imposed more restrictions on research activities and raised the burden outside of research. The current trend of recognizing the country's sovereign rights over genetic resources is likely to continue and widespread worldwide as resource-rich countries are expected to continue protecting their resources. Therefore, our study will help environmental ecology researchers understand ABS and conduct research under the Nagoya Protocol and legal obligations of resource provider countries step by step, from access to benefit sharing.

Occurrence of adult alfalfa weevil, Hypera postica Gyllenhal, was observed at Chinese milk vetch field, and host plant preference of its $1^{st}$ generation adult was observed at greenhouse and Chinese milk vetch field. The over-wintered adult of the weevil appeared from late March and peaked in mid April while the $1^{st}$ generation adult appeared from late April and peaked in late May. However, the occurrence of over-wintered adult was very low contrary to the $1^{st}$ generation adult which was very high with some variations among observed years. In greenhouse, host plant preference of $1^{st}$ adult generation of H. postica was evaluated with 11 different seedlings. H. postica was found to occur in significantly higher number on Chinese cabbage seedling followed by soybean, and kale at 7 days after releasing(DAR). Corn, crown daisy and sorghum were found to be the least preferred with nil occurrence of the weevil. Seedlings damage rate by H. postica feeding at 7DAR was the most severe on Chinese cabbage(60.0%) followed by soybean(50.0%), kale(30.0%), foxtail millet(16.7%), proso millet(13.3%) and lettuce(3.3%) significantly. Also, seedlings damage rate by H. postica at 7DAR in Chinese milk vetch field had shown the similar trend with Chinese cabbage(46.7%), soybean(43.3%), kale(23.3%), foxtail millet(13.3%) and proso millet(13.3%) in greenhouse significantly. Accordingly, results on host plant preference of H. postica from this study can be used as a basic information for safe cultivation of upland crops at near or around green manure crop field.

Three types of Korean style fried rice sauce, 'Kimchi-tomato sauce', 'Doenjang butter sauce', and 'Seafood sauce' were developed in this study. Physicochemical properties such as pH, soluble solid content, acidity, salinity, and texture of sauces were analyzed after application of three different sterilization conditions ($110^{\circ}C/50min$, $115^{\circ}C/30min$, and $121^{\circ}C/20min$). However, no trend was observed in physicochemical properties of each sauce by sterilization conditions. The lightness (L-value) of doenjang butter sauce was higher than the other two sauces. Redness (a-value) and yellowness (b-value) of doenjang butter sauce and seafood sauce were greater than those of kimchi-tomato sauce due to different ingredients. Total viable cells were not detected under all sterilization conditions of the three types of sauce. The sensory evaluation results showed that $121^{\circ}C/20min$ of sterilization scored better than $110^{\circ}C/50min$ or $115^{\circ}C/30min$ sterilization in terms of overall preference of kimchi-tomato sauce and doenjang butter sauce. Overall, the preference of the three types of sauce showed that seafood sauce was best, followed by doenjang butter sauce and kimchi-tomato sauce.

OBJECTIVES : Visibility at night can be improved by using retroreflection for short distances and phosphorescent line markings for long distances. In this study, we analyzed the characteristics of the phosphorescent line marking through a laboratory luminance test. Field performance analysis was performed through tests conducted on the road. We also examined the luminance measurement methods using the digital image obtained during the phosphorescent visibility evaluation. METHODS : In this study, the laboratory luminance test of the phosphorescent line marking was conducted using seven specimens to characterize the luminance changes according to the type of the glass beads, the thickness of the phosphorescent line marking, and the brightness and irradiation time of the light source. Phosphorescent and general line markings were made at 150 m to investigate the field luminance performance. A preliminary review of the luminance measurement methods was made using a digital image from a digital single-lens reflex (DSLR) camera. The measured luminance ratio of the general and the phosphorescent line markings was compared with the calculated luminance ratio using luminance analysis. RESULTS : Through the laboratory luminance test, it was seen that the change in luminance, which corresponds to the brightness of the light source, appears large but the influence of the thickness and irradiation time is low. The field performance test of the phosphorescent line marking conducted on the road involved measuring the luminance on the day the marking was made and 7 days after the marking was made. The luminance was found to be $190mcd/m^2$ at 30 min after sunset and approximately $10-12mcd/m^2$ 4h after sunset. The results of the luminance test were captured using a digital image for each time group. The luminance ratio of the phosphorescent line marking, when compared to that of the general line marking, showed a similar trend within a 13% maximum error. Additionally, when this luminance ratio is compared to the direct field measurement, it could be confirmed that the luminance ratio, as captured in the digital image, showed a similar tendency. CONCLUSIONS : 1) The change in luminance corresponding to the brightness of the light source is significant in comparison with that corresponding to the thickness and the irradiation time. In addition, the results of the field test for the phosphorescent line marking satisfied the phosphorescent fire protection standard. 2) We examined the validity of the luminance measurement method using a digital image and we concluded that the change in the luminance ratio shows a similar tendency in both the cases. The results can form the basis for luminance measurement methodology for the construction and maintenance of phosphorescent line markings.

Korea is far behind other OECD countries in economy-wise productivity: Korea's labor productivity in terms of GDP per hour worked is the lowest among OECD countries. Against the existing productivity gap, there is a worrying sign in Korea's investment trend - rapid fall in machinery and equipment investment with slow increase in R&D investment. The challenge facing Korea is how to transform her economy from catching-up model to a knowledge-based one. The paper shows that, in tandem with the structural changes that today's Korean industries are experiencing, industry's innovation system is also changing. Innovation networks are emerging as the result of economy-wise restructuring since the financial crisis of 1997 and, though still not a dominant force, the newly emerging innovation networks will be the main threads of industry's innovation activities in the future. The changes in industrial innovation system would positively contribute in raising the productivity of the Korean economy. The paper contains a case study on Korea's automobile industry in order to highlight some of main characteristics of the structural changes, in addition to a chapter that gives an overview of the evolutionary paths of the Korea's industrial innovation. The paper assesses that changes can be considered as a positive sign of future growth perspective; but there are further challenges to make the Korea's industrial innovation system effective. The list of such challenges includes strengthening upstream sectors of currently leading industries, expanding the innovation base to SME and promoting technological co-operation between domestic firms and foreign firms.

This study aims at the augmentation of reliability of the long-term rainfall runoff model. To do so agricultural water uses are evaluated by analyzing the effects of small scale irrigational hydraulic structures on long term runoff processes and thereby rainfall-runoff model is modified considering them. As a result the simulation results of the sub-basins having more agricultural reservoirs than the others are disagreed with the observations. The 2nd quarter simulation results show similar trend to it. Especially the farming seasonal results of the drought year as the year of 2008 have many negative discharge values due to the lack of agricultural water uses. This result come from the water uses input data corresponding to not real water uses but water demands. In this study the formulas are derived to estimate the discharges and return ratios and the long term rainfall-runoff model is reformulated based on these. It is confirmed that the errors of the simulation results could be reduced by considering the effects of small scale irrigational hydraulic structures and the reliability of the simulation results improved greatly.

The objective of this study was to investigate an influence of the degree of hotness of powdered red pepper on quality attributes of Kimchi. The extent of hotness was analysed by content of capsaicin and dihydrocapsaicin and ASTA color value, and the change of quality attributes of samples were evaluated by pH, acidity, total microbes, lactic acid bacteria cell count and sensory. Content of capsaicin and dihydrocapsaicin in mild red pepper powder was 11.4mg%, 5.4mg% respectively. And content of capsaicin and dihydrocapsaicin in hot red pepper powder was 149.1mg%, 66.0mg% respectively. Kimchi was made with mild and hot red pepper and stored for 24 days at 5±1℃. The pH of Kimchi made with mild red pepper powder during storage of 12 days was slightly lower than that of Kimchi with hot red pepper powder. The pattern of change in pH of samples showed a reducing trend during storage, and the acidity was vice-versa. At day 0, numbers of total bacteria in mild and hot Kimchi were 5.7, 6.7 log cfu/g, respectively. And at day 3, number of total bacteria in mild and hot Kimchi was same. The change in number of lactic acid bacteria was similar to that of total bacteria. In case of sensory evaluation, Kimchi made with hot red pepper powder showed better sensory scores in overall acceptability.
