LID facilities like bio-retention cells is applied to manage stormwater. LID concept becomes an important part in stormwater management, and the clear understanding of hydrologic performance and hydrologic impact on the corresponding catchment has been needed. In this study, the application of flow duration curves as design strategy is investigated. Bio-retention cells like many LID facilities are installed to reproduce natural hydrologic processes. In this study, the attempt to determine the size of a bio-retention cell is carried out to satisfy the flow duration criteria. From the results, it is shown that "5 mm * the area of a target catchment" which is the current facility design capacity is valid for the drainage area with 20-30% impervious rate. In the 100% impervious catchment where LID facilities are typically installed, the design capacity to intercept stormwater of approximately 47 mm depth is required to reproduce natural flow duration curves. This means that about 11% of the target catchment area should be allocated as a bio-retention cell. However, the criteria of the design capacity and facility surface area should be set at the possible implementation conditions in reality, and site-specific hydrologic characteristics of a target catchment should be considered.

This paper employed typology and stratification as key elements to estimate quality evaluation of vinegar drink through Delphi and AHP(analytical hierarchical process) method to contribute the market expansion of the vinegar drink as a health drink. Through literature research and brainstorming with professionals, the first round of Delphi method was conducted with the open-ended questions including five upper concepts, i.e. 'ingredients', 'production method', 'product characteristics', 'functions' and 'packaging design'. Original study had 50 lower concepts as a result of the first round and added 'marketing' as an additional upper concept. The second and third round of Delphi method have been conducted with closed-ended questions based on the 50 lower concepts resulted from the first round. To seek concordant objectivity among the answers from the survey, the study used Kendall's W coefficient of concordance. 11 items were removed while 16 items were removed at the third round leaving 23 items through second round of Delphi method. For the final round, this study utilized the Pairwise Comparison Method to figure out the relative importance of the 23 items for the prioritization. Finally, current study formulated the final items which should be considered as an important factor in the quality evaluation of vinegar drink.

This study investigated how Korean media covered Japan's position on her past history issues proposed by Abe' Shinzo's cabinet. The researchers adopted Entman's analytical tools for frame analysis and the concept of "frame changing" proposed by Chi and McCombs. The analysis rendered several propositions. First of all, the Korean media's coverage on Japan's past history issues focused heavily on the current conflict among two nations rather than constructing a futuristic viewpoint based on a thorough discussion on the historical background of the topic. In addition, it emphasized that the conflict should be resolved by political negotiations between the two governments. Secondly, the news coverages depicted "comfort women" issues as the prime element of the conflict, describing Abe's cabinet as the major inducer of the conflict. Ideological and political divisions among Korean media did not significantly influence on how they frame Japan's past history issues. In general, Korean media took the stance of ethnocentric "patriotic journalism," advocating Korean government's position and covering the emotional reactions from Korean public instead of providing through and through objective news coverage on Japan's past history issues.

purpose of this study was to analyze high school chemistry teachers perception of the Chemistry I & Chemistry II in the 7th national curriculum and their demands on the revision of curriculum. A nationwide survey was administered to obtain the responses from 108 high school chemistry teachers. More than half of the participants thought the current curriculum of Chemistry I and Chemistry II needed revising. As the results, a major drawback of Chemistry I was a difficulty in explaining phenomena due to absence of basic concepts, and that of Chemistry II was an excess of the contents for high school science courses. Unfortunately, it was found out that inquiry activities existed only in name, especially in case of Chemistry II. Regarding the manner of content organization of Chemistry I in new curriculum, demand on a concept-based approach outnumbered theme-based approach. For revising Chemistry, the majority of participants demanded basic chemistry concepts to be introduced, without supplementation of quantitative approaches and deepening level of concepts. An urgent request for Chemistry II was reducing content by shifting relevant concepts to Chemistry I. Implications for high school chemistry education including revising curriculum were discussed.

The current encased-concrete deep corrugated steel plate has an arch type plate structure, which is a compressive strength-dominant structure that has a small moment due to its arch shape. Therefore, it increases the strength against compression by adding reinforcements to make concrete-filling spaces for increasing the compressive strength and forming cross sections that contain reinforced concrete. In this study, the safety factor of the new-concept encased-concrete bridge plate member was evaluated by comparing the compressive strength obtained from the compressive tests, flexural tests and the design compressive strength determined by using the Canadian Highway Bridge Design Code (CHBDC, 2003), which is a design standard for the encased-concrete bridge plate structures. The results of the safety factor evaluation using the design compressive strength and the test results showed that the safety factor was well above the appropriate value 2.0, which could be adjudged very conservative. If the safety factor based on this study results is considered and applied to the design, economical construction will be possible due to the reduced cross section and construction cost.

As current business environment is experiencing radical changes, interest in brands has increased theoretically and practically. The growing interest in brands creates the need for brand equity measurement and management models that help companies manage and fortify brands continuously. Given the situation, this study analyzes effects of brand equity on purchasing behavior of consumers. Outcomes of this study can be employed as integrated brand management system in order to satisfy corporate needs for systematic brand management. This model has been developed in an effort to transcend varied limitations of other previous studies and existing models. Consequently, the practical value of this model is highly expected. Beyond the mere concept of brand for establishing differentiated position against competitors, contents of the study cover extended forms of brand equity and brand performance. This model has been tested through practical applications of fifteen brands from three product categories. Despite several disparities among the categories, the study has revealed that the overall market performance of the brands is correlated with the brand power and other factors in the model. As the importance of brands is growing, brand management is an essential step for power branding. And brand management requires extensive brand diagnosis. The practical results of this study indicate that companies should put an emphasis on brand-oriented management as core strategy of their business.

Natural convection heat transfer rates in a vertical pipe were measured for $Gr_H$ number from 2.1x$10^6$ to 1.2x$10^9$. Using the analogy concept, heat transfer experiments were replaced by mass transfer experiments. A cupric acid - copper sulfate ($H_2SO_4-CuSO_4$) electroplating system was adopted as the mass transfer system and the mass transfer rates were measured. Comparison of the results with the existing laminar and turbulent natural convection heat transfer correlations on a vertical plate showed very good agreements except for the high $Gr_H$ case, where the boundary layer inside the vertical pipe interferes. The agreements showed the usefulness of the analogy experiment method. Using 3 different anode size and 6 different geometrical configurations, the effects of the anode size and position were explored. As expected, the anode size and position do not affect the limiting currents for most cases. These results will be used as the experimental background for the positioning and sizing of the anodes for a more complex experiment.
