The textile industry is petting increased effort to manufacture the value-added products that gives the differentiated characters at every level of fiber and fabric production. The color is an important element to be used strategically in order to push up the value-added design. The colors of apparel products have a close relationship with the skin colors of consumers and their preference colors. This study was carried out to cluster the skin colors of the Korean women into several similar skin colors and to analyze their preference colors by the classified groups. We measured the skin colors of 354 Korean women. With color spectrometer, JX-777, we measured 4 points of the body; cheek with removing cosmetics off, forehead, rear neck and arm on the interior part near elbow. All subjects had been shown with 40 color chips and answered the preference colors and preference colors of apparel. Data were analysed to classify skin colors using K-means Cluster Analysis and Duncan test, Frequency and Chi square test on the preference colors about the clustered 3 groups. In doing so, we used in SPSS Win 10 statistical package. Findings were as fellows: 1) The skin colors of the Korean women were clustered into YR, R, and Y skin colors. The majority of the subjects, 324 observations had YR skin colors and the subjects were classified into 3 kinds of skin color groups who had YR skin colors. 2) The average skin colors of total 324 subjects was 5.23YR 6.49/4.09 in Munsell Color System(MCS), 66.56 in L value, 10.53 in a value, and 20.67 in b value. 3) The average skin color of Type 1 was 7.98YR 6.24/4.14 in MCS, 64.10 in L value, 15.05 in a value, and 24.0 in b value. For Type 2 was 7.30 YR 6.56/3.28 in MCS, 67.24 in L value, 6.89 in a value, and 18.4 in b value, and Type 3 was 7.01 YR 7.20/4.38 in MCS, 73.53 in L value, L 16.04 in a value, and 24.87 in b value. 4) The average face color of total 324 subjects was 7.31YR 6.65/3.56 in MCS, 68.13 in L value, 9.53 in a value, and 20.18 in b value. 5) The average face color of Type 1 was 4.19 YR 6.92/5.05 in MCS, 70.78 in L value, 13.2 in a value, and 25.32 in b value. For Type 2 was 5.24YR 6.33/3.79 in MCS, 64.94 in L value, 9.84 in a value, and 19.08 in b value. Type 3 was 5.4YR 6.85/4.68 in MCS, 70.1 in L value, 11.73 in a value, and 23.92 in b value. 6) The difference of mean values between the clustered 3 skin color groups showed significantly different except the a value of neck and H value of cheeks and H value of foreheads. 7) All 3 groups showed that the most preference colors and the most preference colors of apparel was 5R 4/14. and their preference colors were much more than the preference colors of apparel.

Purpose - The focus of this study is to investigate the structural influences such as brand value, relationship value, market orientation, long-term orientation, and performance. The effects of brand value and relationship value on the differences on transaction performance in b2b was investigated. Research design, data, and methodology - The subject of this study was a liquor and beverage distribution company that deals in b2b. The research hypothesis is based on literature of the preceding research analysis of brand value, relationship value, market orientation and long-term orientation. This study has constructs that was defined operationally by referencing previous studies. Operational questionnaire was used to investigate the target key staff who work in the liquor and beverage distribution company. 178 survey data were used for empirical analysis to prove the hypothesis. This study used structural equation techniques(AMOS) to prove the research hypothesis. Results - The main results of this empirical study were as follows. First, supplier's brand awareness has a positive effect on market orientation, but did not affect long-term orientation. Brand awareness of suppliers indicates that they are not directly related to long-term orientation. Second, supplier's brand image has a positive effect on market orientation and long-term orientation in b2b transaction. So, the brand image and reputation of the supplier suggest that it is important for the b2b transaction to have a market orientation tendency or a long-term orientation. Third, supplier's relationship value has a positive effect on long-term orientation, but does not affect market orientation. Relationship value indicates that they are not directly related to market orientations of the buyer. Fourth, Market orientation has a positive effect on long-term orientation and marketing performance and long-term orientation has a positive effect on marketing performance in b2b. Additionally, the buyers market and long term orientation are important factors in marketing performance in b2b. ' Conclusions - Based on empirical results, this study confirmed that brand image rather than brand awareness positively influenced long-term orientation as well as market orientation in b2b. Relationship value can be found in transactions, which is important for long-term orientation. Especially, these findings are suggestive in the consumer goods distribution market.

The b-value in the magnitude-frequency relationship logN(m) = $\alpha$ - bmwhere N(m) is the number of earthquakes exceeding magnitude m, is important seismicity parameter In hazard analysis. Estimation of the b-value for earthquake data observed on KSRS array network is done employing the maximum likelihood technique. Assuming the whole Korea Peninsula as a single seismic source area, the b-value is computed at 0.9. The estimation for KMA earthquake data is also similar to that. Since estimate is a function of minimum magnitude, we can inspect the completeness of earthquake catalog in the fitting process of b-value. KSRS and KMA data lists are probably incomplete for magnitudes less than 2.0 and 3.0, respectively. Examples from probabilistic seismic hazard assessment calculated for a range of b-value show that the small change of b-value has seriously effect on the prediction of ground motion.

The purpose of this study is to examine the impact of relationship quality on customer value, customer satisfaction and relationship retention intention in the B2B transaction relationship. For the empirical study, we conducted a survey of the PCB corporation's client companies and used 110 surveys of them for analysis. The results of this study are summarized as follows : First, trust, relationship satisfaction, unity and performance as factors of relationship quality had significantly positive effect on relationship retention intention by the medium of customer satisfaction. Second, utilitarian value which is a parameter did not have significantly effect on customer satisfaction and relationship retention intention. Whereas, hedonic value which is influenced by relationship satisfaction, unity and performance had significantly positive effect on customer satisfaction and relationship retention intention. These results are not treated weightily in the preceding studies and managing the hedonic value in B2B transaction relationship is considered important to improve the customer satisfaction and relationship retention intention.

The purpose of this study is to research and development of 'Korea B(Benefit)-impact Model' for Sustainable Development. A concept evaluation model is 'B(Benefit)-impact model' in U.S.A. We use the results of surveys that examined the importance of social value issues to stakeholders in Korea to implement the benefit-impact model in Korea. In particular, in this paper, we use the KSI(Korean Sustainability Index) survey data conducted by the Korea Standards Association to evaluate the social value of the construction industry for representative stakeholders in the construction industry. The social value pool and the activity indicator pool used for the survey are created based on relevant International Standards; ISO 26000, ISO 14001, ISO 37001. As a result, Korea B-impact model for construction industry included the following five core social value issues; Strengthen transparency of corporate management, Ensure fair employment and employment relations, Efforts to prevent corruption, Conduct fair competition, Efforts to prevent environmental pollution. In addition, the US B-impact model has three limitations. First, it is unclear whether the key indicators have been derived while considering all issues of social value. Second, US B-impact model indicators are developed by the social responsibility experts, so it is necessary to review by stakeholders in each industry. Finally, it would be more effective for companies to use the B-impact model index as a more detailed activity indicator. When developing a Korea B-impact model, the following methods are used to supplement it. First, we reviewed all social value issues using international standards. Secondly, we used the KSI(Korean Sustainability index) survey results to derive the importance of the social value issue of construction industry in Korea. Finally, we have clearly matched the activity indicators by social value core issues based on the GRI Standard so that companies can actually use the Korea B-impact model for the construction sector. The detailed development stages and results of this study are as follows;.

김치의 숙성도를 평가하기 위한 한 방법으로 김치의 숙성과정 중 자연적으로 유출되는 김치액의 색상 변화를 색차계를 이용해서 측정하고, 또한 이들 결과를 성분분석과 관능적인 평가와 비교 조사하였다. 성분분석과 관능검사 결과는, 16$^{\circ}C$에서 숙성 3일째 김치의 숙성 적기 pH인 4.3에 달하였으며 이때 비타민 C 및 carotenoids 함량도 거의 최고치에 달하고 신맛과 조직감도 적당하였다. 숙성온도 4$^{\circ}C$에서는 숙성 6일후에도 미숙단계에 있었다. 숙성온도 16$^{\circ}C$에서 김치액의 $L^{*}$ 값은 숙성기간 중 뚜렷한 변화를 나타내지 않았다. 반면 $a^{*}$ 값은 숙성 4일까지는 상승하다가 이후 급속히 감소하였으며 $b^{*}$ 값은 숙성 3일까지는 증가하다가 그후 거의 변화가 없었다. 김치액량, pH 및 산도는 김치액의 $L^{*}$ 혹은 $b^{*}$ 값과, carotenoids 함량은 다만 $a^{*}$ 값과 높은 상관관계를 나타냈다. 김치액의 색상으로 김치의 숙성 정도를 평가하기 위해서는 $a^{*}$ 혹은 $b^{*}$ 간을 지표로 삼는 것이 바람직하였다. 즉, $a^{*}$ 값이 담금 초기와 비교해서 동등 혹은 낮은 값을 나타내거나 $b^{*}$ 값이 거의 변화가 없을 때는 과숙기에 이르렀다고 할 수 있었다. 김치의 적숙기를 예측하는 한 방법으로 $a^{*}$ 와 $b^{*}$ 의 비( $a^{*}$ / $b^{*}$ )를 이용할 수 있었다. 즉, $a^{*}$ / $b^{*}$ 의 비값이 1이상 흑은 1에 가까울 때는 미숙기, 0.8 부근 일때는 적숙기, 0.8보다 작아 질수록 적숙기에서 과숙기로 점차 옮아감을 알 수 있었다.

본 연구는 바나나 첨가에 따른 식빵의 품질 특성을 알아보고자 하였다. 반죽의 mixograph와 stickiness, 발효율, TPA, 비용적, 영상분석, 색도, 수분함량, 기호도 검사를 통하여 분석하였다. Mixograph의 peak time(min)는 모든 시료가 4~5분을 나타냈지만, peak value(%)의 경우 CON, B10, B20 시료가 60% 이상, B30, B40이 60% 이하를 나타냈다. Stickiness 측정결과, 바나나 첨가량이 늘어나면서 점착력이 낮아짐을 알 수 있었다. 발효율은 전반적으로 증가하였으나, B40 시료의 경우 75분 이후에는 감소하는 경향을 보였다. 껍질과 속질의 색도 측정결과, 명도 L값은 CON이 가장 높았고, 적색도 a값은 B40이 가장 높았으며, 황색도 b값 역시 B40이 가장 높았다. pH 측정 결과, B40이 가장 낮은 수치를 보였고, 바나나 첨가량이 많을수록 pH가 낮아지는 경향을 보였다. 바나나 첨가가 제품의 부피와 비용적에는 부정적인 영향을 끼치는 것을 알 수 있었으며, crumbScan을 통한 영상분석 결과, 껍질두께, 기공의 찌그러짐에서 유의한 차이는 나타나지 않았다. 반면, 기공의 조밀도에서는 CON의 값이 774.33으로 가장 낮았으며, B40의 값이 927.66으로 가장 높게 나타났다. Hardness는 유의한 차이를 보이며 B40이 가장 낮았고, 대조구가 가장 높았다. 수분함량은 전체적으로 유의한 차이가 있었고, CON의 값이 가장 높았으며, 바나나 첨가량이 늘어남에 따라서 그 값이 줄어드는 것을 확인할 수 있다. 관능검사 중 기호도 검사 결과, B20이 가장 높은 평가를 받았고, B40은 전체적 기호도에서 가장 좋지 않게 나타났다. 특성차이 검사결과, 바나나 첨가량이 부피를 크게 하는데 부정적인 영향을 끼친다는 것을 확인할 수 있었다. 전반적인 품질특성 결과와 관능검사 결과에 따르면, 바나나를 20% 첨가하는 것이 품질과 기호도 측면에서 최적이라 사료된다.
