We propose a method to analyze user requirements to design a virtual reality-based risk management system. This paper presents surveys, interviews, prototype evaluation methods, and implementation process. Architectural heritage is easily exposed to natural and artificial dangers caused by various material combinations and structural features. So, risk management of cultural heritage plays a key role in preserving and managing cultural heritage. However, risk management has been carried out through empirical methods using distributed data. This study analyzes user requirements for designing functions and interfaces of VR-based risk management system and evaluates prototypes to overcome the above problems. As a result, most heritage managers wanted a system function to support risk analysis and response. They also found that they prefer 2D information such as existing drawings and photos rather than 3D information. The results of the user requirements analysis derived from this study will be used to create risk management applications.

본 연구의 목적은 도시개발의 영향을 평가하고 물순환 개선시설의 적절한 배치를 설계하기 위한 물순환 해석 모형을 개발하는 것이다. 개념적 매개변수를 사용하는 기존의 집중형 수문모형으로는 도시개발로 인한 토지이용 변화 등의 유역 특성 변화를 적절히 모의하는데 한계가 있으며, 최근 활발히 연구되고 있는 분포형 수문모형은 입력자료 구축 및 모형 구동에 많은 시간과 노력이 필요하여 다양한 도시설계 대안을 평가하기에는 적절하지 못하다. 유역 물순환 해석 모형(Catchment hydrologic cycle Analysis Tool, 이하 CAT)은 이러한 배경을 토대로 개발된 물리적 매개변수 기반의 링크-노드 방식의 물순환 정량화 모형이다. CAT은 기존 개념적 매개변수 기반의 집중형 수문모형과 물리적 매개변수 기반의 분포형 수문모형의 장단점을 최대한 보완하여, 도시유역 개발 전 후의 장 단기적인 물순환 변화 특성을 정량적으로 평가하고 물순환 개선시설의 효과적인 설계를 지원하기 위한 물순환 해석 모형이다. 개발된 모형의 평가를 위하여 설마천 유역을 대상으로 모의를 수행하였으며 출구점인 전적비교의 6개년(2002~2007) 동안의 시간별 하천 유출량 자료를 이용하여 모형의 보정(2002~2004)과 검정(2005~2007)을 실시한 결과, 보정과 검정기간의 Nash-Sutcliffe 모형효율계수는 각각 0.75와 0.89로 나타났다.

In order to understand the nature of dendritic zinc growth, electrochemical zinc redox reaction on nickel plate was investigated in aqueous solutions containing different concentrations, 0.2, 0.1 and 0.02 $mol{\cdot}dm^{-3}$ (M), of zinc sulfate ($ZnSO_4$) or zinc chloride ($ZnCl_2$). Zinc ion was efficiently reduced and oxidized on nickel in the high-concentration (0.2 M) solution, whereas relatively poor efficiency was obtained from the other low-concentration solutions (0,1 and 0.02 M). Cyclic voltammetry (CV) analysis revealed that the 0.2 M electrolyte solution decomposes at more positive potentials than the 0.1 and the 0.02 M solutions. These results suggested that the concentration of electrolyte solution and anion would be an important factor that suppresses the reaction of the zinc dendrite formation. Scanning Electron Microscopy (SEM) data revealed that the shape of dendritic zinc and its growing behavior were also influenced by electrolyte concentration.

We investigated the residual contents of sulfur dioxide ($SO_2$) on the 280 kinds of herbal medicines distributed at 8 cities including in Seoul, Busan, Daegu, Gwangju, Jecheon, Yeongju, Geumsan and Jeonju in Korea. The residual contents of $SO_2$ were determinated by modified Monier-Williams method. The residual contents of $SO_2$ were not detected at 206 products in total 280 products. However, it was detected below 100 ppm in 39 products, between 101 and 1000 ppm in 30 products and exceeded 1000 ppm in 5 products. $SO_2$ contents ranged 11 ${\sim}$ 2339 mg/kg (mean 293 mg/kg) at domestic samples distributed. Regardless of region, $SO_2$ contents were not found at Notopterygii Rhizoma, Ligustici Scinensis Rhizoma et Radix, Bombyx Batryticatus, Coicis Semen, Cnidii Rhizoma, Anemarrhenae Rhizoma, Gardeniae Fructus, Alismatis Rhizoma. But it's found at Batatatis Rhizoma, Paeoniae Radix and Codonopsitis Radix of every region collected the samples. $SO_2$ contents were not detected at 58 products which collected cultural fields of dometic. After treated with water wash and hot water extraction, the reduction rates of sulfur dioxide were appeared with 14.3% ${\sim}$ 40.4% and 55.2% ${\sim}$ 100.0%, respectively. These data will be used to establish a criteron of residual sulfur dioxide in herbal medicines.

This study assessed the effect of color marketing in the RTD coffee industry in Korea. In order to investigate the effect of color marketing, this study measured the characteristics of color marketing as well as brand image and attitude in accordance with behavioral intention to purchase. Data were collected using questionnaires, and a total of 310 questionnaires were distributed with 298 entered for data analysis. Frequency analysis, factor analysis, correlation, and multiple regression analysis were tested using SPSS. A total of seven factors were extracted, including brand attitude, purchase intention, association, identification, brand awareness, symbolism, and attention. Significances were found between brand awareness and identification (p<0.001) and attention (p<0.001). In the relationship between characteristics of colors and brand attitude, significances were found in identification (p<0.001), attention (p<0.001), and association (p<0.001). Further, brand attitude and brand awareness had a significant positive effect on purchasing intention of RTD coffee. Results of this study suggested that color marketing is a good marketing tool to persuade potential consumers to purchase RTD coffee based on brand attitude and brand awareness.

The purpose of this study was to develop a large representative data base of market information for jeans apparel. This study was to observe consumer buying behavior and to determine the market share of various brands depending on several variables such as age and distribution regions. This study also analyzed the major factors in purchasing jeans for 17-29 age groups. The 660 questionnaires were distributed and 618 reliable ones were used for statistical analysis. A SAS statistical package including frequency' table, Chi-square test, factor analysis, analysis of variance(ANOVA), Duncan's multiple range test was used. The results of this study showed that consumer possessed about 6 pairs of jeans and bought about 3 pairs of jeans per year. The most recently purchased brand was Nix. Lots of brands were statistically significant at the segmented three age groups and in the five different distribution regions. The most popular type of design was the basic style. The result of factor analysis indicated 4 factors(quality/comfort, famous brand/fashion, mood/extrinsic attitude, economy). The result of ANOVA represented that three factors among them have influenced on the preferred design types.

The purpose of this study was to empirically investigate the relationship among fashion brand experience, brand loyalty, relationship quality, and repurchase intention. The 420 survey questionnaires were distributed among the consumers in their 30s and 40s who had experience buy fashion brands products through convenience sampling in Seoul. Due to the reliability of data, 120 samples were discarded and 300 samples were put to actual analysis. By using SAS 9.4, data were analyzed for frequency analysis, reliability analysis, correlation analysis. The results of the study are as follows. First, the fashion brand experience which is consist of sensory, affective, behavioral and intellectual experience had positive effects on brand satisfaction and brand trust. Second, brand trust and brand commitment and the relationship quality of brand satisfaction, only satisfaction and commitment affects brand loyalty significantly. Lastly, brand loyalty had significantly effect on repurchase intention. It presented the potential to use the brand as a strategic tool to build strong brand assets, along with providing specific ways to secure differentiated competitiveness in the fashion brand market. It is also thought to be meaningful in that we presented a practical strategy to build and strengthen a lasting bond with consumers by looking at the impact on the quality of the relationship.
