The purpose of this paper is to analyze the factors, which have influence upon changes of hydrological environment in time series, and evaluate water balance changes caused by urbanization. The results of the analysis and evaluation are as follow: At first, the river runoff at Gwangju River Basin keep base flow of river by storage capacity recharged in June to September and show peak in August and minimum flow in May. The groundwater recharge by urbanization accounted for 46.1% of rainfall at early-urban stage, and decreased to 36.5% and 29.9% in the 1960's and the 1990's respectively, and is likely to decrease to 27.8% in the 2010's. On the other hand, the overland flow was 9.6% of rainfall in the 1960's and 16.2% in the 1990's, and is likely to increase to 18.3% in the 2010's. When such a phenomenon is kept continuously, distorted water balance shall be worsened to create not only frequent occurrence of urban flood but also decreased base flow of Gwangju River to accelerate dry stream phenomenon. The time series study on urban redevelopment and environment maintenance describes distorted phenomenon to supply the information for nature-friendly land use, and examines relations between human activities and natural environment.

Most pharmaceutical licensing deals are made in the early stage of drug development. While this development process is not unique for complicated technology, a special feature of drug development is that it is highly regulated and a well-defined process. Its statistics in terms of costs and chances of technical success have been researched extensively. This enables relatively detailed calculations as benchmarks for actual deals to be made. Based on such calculations and on the analysis of licensing terms in published agreements, various companies offer quite expensive information, databases, software programs and consultation services to help establish what might be reasonable economic terms in a licensing deal. Over the years, pharmaceutical royalties have been the subject of various articles in journals. Most specific on this subject was the article on determining pharmaceutical royalties. Many other articles are about a more general nature deal with determining reasonable royalty rates, evaluating and underpinning the empirical value and usefulness of the 25% rule. The object of this article is to provide a relatively simple analytical approach based on the major economic terms underlying pharmaceutical licensing deals. The aim is to enhance the understanding of the relations between the major factors involved. Details are disregarded, as generally, where the terms of licensing deals depend on predictions over a considerable length of time, the value of detail is limited. Some specific issues addressed by the approach are the impact on profits of large investments, high risks and long development times characteristic of drug development, the consequent strong impact that the ultimate sales levels and operating margins may have on what might be considered a reasonable royalty rate, and the relationship between upfront payments and milestone payments to be paid during pharmaceutical development and the royalties due once the drug enters the market.

This study aims to investigate the relation between adult attachment types and communication types of child who attend childhood-care center and their mothers, offer general information of parent education with the importance of language within family as the basic material and provide data and materials to improve communication skills of infants who attend childhood-care center. Based on these goals, study subjects in order to examine the relation between adult attachment types of mothers and communication types of child were established as follows: 1. What is the relation between adult attachment types of mothers and communication types of child? 2. How do attachment types of mothers affect on communication skills of child? The objects of this study were child aged 3 - 5 years old who attend children's house in Daejeon Metropolitan City and their mothers. Measurement tool of adult attachment and tool of communication types of child were used to them for analysis. As the results of the study, there was no correlation between the types of adult attachment and communication types of child. On the contrary, there were passive correlations between dependency and negative communication types and between insecurity and positive communication types. Based on the correlation analysis, insecurity among types of mothers' adult attachment was a major variable that can predict communication skills of children's in the result of multiple regression analysis.

This study is to analyze the present condition of internal dance troupes' web sites contents and through this study, we aim at suggesting beneficial plans not only for constructing better web sites and contents for national dance troupes but also for contributing to the development of national dance troupes. In order to achieve this study's object, we selected eight dance troupes that run their own web sites and examined their contents. the conclusions are as following. First, among internal professional dance troupes, Korea National Ballet, Seoul Ballet Theatre and Universal Ballet Company offer the best contents at their home pages and they have the most lively community concerned activities at their internet web sites. Second as for the web sites of municipal(provincial) dance troupes, those of Gyeonggi provincial dance troupe, Daejeon municipal dance troupe, Busan municipal dance troupe, Seoul municipal dance troupe Incheon municipal dance troupe have lots of contents briskly carried on, but those of the others need complementary measures. Third, Seoul ballet theatre and Universal Ballet Company offer lots of information about their activities to satisfy their customers and make the maximum use for public relations ; performance news, the introduction of their members, the story of ballet press reviews, new letters. On the other hand, at the web sites of Metropolitan Dance Theater Provincial Dance Company, there are much fewer contents about their activities which doesn't lead customers to visit their webs.

Recently innovation cluster has been emphasized as a valid policy measure for innovation. For suggesting a new model of innovation cluster, we conducted literature review for the theories of regional innovation system(RIS) and innovation clusters. As a result, the success factors of innovation cluster were classified into system measures, physical measures, and social(human resources) measures from the perspective of RIS. The case of Gyeonggi province's innovation cluster policy was examined for an empirical analysis. For an in-depth analysis, a survey for the tenant companies in Pangyo technovalley(PTV) was conducted. As a result, it was found that Gyeonggi province's innovation cluster policy is evolving from 'a government-initiated system' to 'the 3rd-generation convergence RIS' and that PTV is closely related to the system measures of 'support for up-to-date management and technology information' and 'support for academic-research-industry cooperative research and technological cooperation,' physical measures of 'strengthening the function of PTV support division' and 'shared research equipment and other infrastructures,' and social measures of 'legal, financial, and administrative support system' and 'public childcare facilities'. Also, technology sector was divided into IT and non-IT for a validity check to find out that there was no significant difference in all factors, except for the public relations factors. This study is expected to provide resources for other related researches.

The objective of this paper is to support accurate pavement condition assessment and decision of proper maintenance method and time by conducting visual inspection and calculating the remaining life of pavement from falling weight deflectometer(FWD) data. Each was implemented in the same long-term performance pavement(LTPP) sections. Visual inspection was executed to measure pavement condition indices such as crack, rutting and international roughness index(IRI) and the Seoul Pavement Index(SPI) was calculated based on these results. The dynamic modulus was back-calculated from the FWD data. The remaining pavement lives were determined from equivalent single axle loading(ESAL) and FWD data. Correlation of maintenance priority by each result value was examined. Consequently, the correlation between remaining life to Crack and Rutting was higher than the other factors or indicesbecause IRI is not related to FWD value and SPI value consists with IRI value and other indices. The R-square value of correlation of FWD with Crack and Rutting was 0.65, which indicated an insufficient correlation. Consequently, when decision of maintenance of method, time, etc. is determined, FWD data have to be considered with Crack and Rutting because of those relations.

This study was examined for information of management of bluegill, Lepomis macrochirus which is disturbance species of underwater ecosystem in Korea. Research of bluegill population was investigated spring-summer and autumn periods in the Han river system from 2009 to 2012. Bluegill inhabited mostly lakes, and restrictedly lived at still area in downstream. The range of relative abundance were 0.2~18.2% in individual number and 0.2~40.0% in biomass and it was subdominant or superiority species for the most part of the lakes. Population structure were analyzed r-strategy in Lake Soyang and Paldang and K-strategy in Lake Uiam and Cheongpyeong. But Lake Chungju was estimated transition period from K-strategy to r-strategy. Condition factor and body weight-total length relations were presented favorable condition. For the nesting, bluegill was formatted the group. And the water depth and the distance from shore were mean 56.3 cm and 191.9 cm respectively in nesting ground. Diameter and depth of nests were mean 42.4 cm and 9.7 cm respectively. These results are available for research of population dynamics and reproductive ecology of bluegill.

As whole genome sequences of many organisms have been revealed by small-scale genome projects, the intensive research on individual genes and their functions has been performed. However on-memory algorithms are inefficient to analysis of whole genome sequences, since the size of individual whole genome is from several million base pairs to hundreds billion base pairs. In order to effectively manipulate the huge sequence data, it is necessary to use the indexed data structure for external memory. In this paper, we introduce a workbench system for analysis and visualization of whole genome sequence using string B-tree that is suitable for analysis of huge data. This system consists of two parts : analysis query part and visualization part. Query system supports various transactions such as sequence search, k-occurrence, and k-mer analysis. Visualization system helps biological scientist to easily understand whole structure and specificity by many kinds of visualization such as whole genome sequence, annotation, CGR (Chaos Game Representation), k-mer, and RWP (Random Walk Plot). One can find the relations among organisms, predict the genes in a genome, and research on the function of junk DNA using our workbench.

Korea's social cooperatives were enacted by law in December 2012. However, it is in the process of being settled and has not been established institutionally. So social cooperatives are failing. The purpose of this study is to reduce these failures. To this end, this study distinguished between co-operatives and social co-operatives. Also, the characteristics and concepts were identified. That is why we want to help our social cooperatives in Korea. The results based on the literature research are as follows. First, in order for domestic social co-operatives to be sustainable, the seven principles of co-operatives must be observed. In particular, the sixth principle is important. It is important to form a social cooperative association and to communicate with local cooperatives. Their communication is less likely to fail because they can share management support information, education, promotion, and strategies. Second, there is a need for a plan that can be applied not only to the government but also to general enterprises in order to support social co-operatives. Third, related policies of the government and the private sector should be designed and managed in an integrated manner to promote social cooperatives. Fourth, public relations should be promoted through campaigns to inform the public that the meaning of social cooperatives is for the public good. In addition, the government needs to build a program that fosters professionals who can foster social co-operatives. In conclusion, it is meaningful that this study suggests possible ways to develop social co-operatives in Korea, and provides support to the Korean government.

The study investigated the linguistic characteristics of middle school students' writing on the themes of earth science through analysis of its genre and register. Data for analysis included $7^{th}$ grade and $9^{th}$ grade students' writings about 'global warming' and 'classification of rocks'. The results of this study include: First, many students were not accustomed to writing in genre, especially exposition genre. Second, in terms of ideational meaning, the material verbs representing action or doing were more dominant than relational verbs that are related to the attribute or definition of things, and additional logical relations were predominant. Third, regarding interpersonal meaning, agents, emotions, subjective opinions appeared in the writings and students did not express their ideas conclusively and revealed feelings of doubt and uncertainty about their knowledge. Fourth, as for textual meaning, most students listed fragments of information using additional conjunctions in simple structures and were not accustomed to writing texts with organizing structures, logical patterns, cohesion, and coherence. From these results, we argued that the scientific writings should be emphasized in science learning that aims to foster scientific literacy. In addition, we discussed the necessity of improving science teachers' perceptions on scientific writing as well as setting up a specific plan in the national curriculum.
