  • The purpose of this study was to examine the visual evaluation of image according to the style, hue, value, and chroma of the male clothing and the preference of image. A quasi-experimental method was used for this study. The first factorial design was the $2{\times}3{\times}2{\times}2$ (style of upper clothes ${\times}$ hue ${\times}$ chroma ${\times}$ color of trousers), and the second factorial design was the $2{\times}3{\times}2$ (style of upper clothes ${\times}$ value ${\times}$ color of trousers). The styles of upper clothes were a soutien collar casual jacket and a polo shirt. The subjects were 509 female college students living in Seoul. Factor analysis showed five image categories of men's clothing: initiative, dignity, politeness, activity, and mildness. Yellow was evaluated as having the highest initiative and activity. Blue was shown to have lower mildness than red and yellow. The high saturated chroma was perceived to be higher initiative and activity than low chroma. The shirts were evaluated higher in activity and mildness than the casual jackets were. The beige pants were perceived to be higher in dignity and mildness than the dark blue pants. The high chroma jackets were perceived to be higher in both initiative and activity than the low chroma jackets. The navy blue pants with the upper clothes in low chroma blue were perceived to be higher in politeness than with the upper clothes in low chroma red or yellow. The low value clothes were perceived to be higher in both initiative and dignity.

  • In this study, a value-based children's financial education program was developed focusing on the values of each financial management area needed for children. According to 'quasi-experimental design - non-equivalent control group design', an experimental group and a control group were formed for children in the lower grades of elementary school, and a value-based child financial education program was executed, and then the program was applied to children's personal financial management. The effect on the value propensity for each area was evaluated. As a result of the quantitative evaluation, it was confirmed that the 8 values of the children in the experimental group were significantly improved compared to the children of the control group, so this program was effective in enhancing the values of each of the 8 areas of personal financial management needed for children. In addition, the children in the experimental group showed significant improvement compared to the children in the control group in the cognitive, justice, and psychodynamic levels of values. It has also been found to be effective in enhancing as a result of the qualitative evaluation, various positive changes were found in the cognitive, affective, and psycho-dynamic dimensions about the values of each financial management area for children. From a positive perspective, it was found that it plays a useful role in cultivating the values of each area of positive personal financial management.

  • This study has evaluated the genomic estimated breeding value (GEBV) of the commercial Hanwoo population using the genomic best linear unbiased prediction (GBLUP) method and genomic information. Furthermore, it analyzed the accuracy and realized accuracy of the GEBV. 1,740 heads of the Hanwoo population which were analyzed using a single nucleotide polymorphism (SNP) Chip has selected as the test population. For carcass weight (CWT), eye muscle area (EMA), back fat thickness (BFT), and marbling score (MS), the mean GEBVs estimated using the GBLUP method were 3.819, 0.740, -0.248, and 0.041, respectively and the accuracy of each trait was 0.743, 0.728, 0.737, and 0.765, respectively. The accuracy of the breeding value was affected by heritability. The accuracy was estimated to be low in EMA with low heritability and high in MS with high heritability. Realized accuracy values of 0.522, 0.404, 0.444, and 0.539 for CWT, EMA, BFT, and MS, respectively, showing the same pattern as the accuracy value. The results of this study suggest that the breeding value of each individual can be estimated with higher accuracy by estimating the GEBV using the genomic information of 18,499 reference populations. If this method is used and applied to individual selection in a commercial Hanwoo population, more precise and economical individual selection is possible. In addition, continuous verification of the GBLUP model and establishment of a reference population suitable for commercial Hanwoo populations in Korea will enable a more accurate evaluation of individuals.

  • 디자인산업은 국가 경쟁력의 근간이 되지만, 현재 그 성장 동력에는 한계가 나타나고 있다. 이러한 이유는 정성적 가치기반의 디자인산업의 특성으로 객관적이지 못한 평가방식이 원인이며, 이로 인하여 디자인산업의 근간이라 할 수 있는 디자인전문기업의 산업적 경쟁력을 약화시켰다. 그래서 본 연구에서는 디자인의 정성적 가치 체계를 보강하고, 디자인의 산업적 경쟁력 강화를 위하여, 디자인에 대한 객관적인 가치평가 요인을 도출하고 이러한 요인들이 디자인전문기업의 해외 경쟁력과 어떠한 관계를 가지는 지를 규명하여 우리나라 디자인산업의 독자적인 경쟁력 강화방향을 모색해 보고자 하였다. 먼저 본 연구에서는 디자인에 대한 객관적인 평가요인을 측정 평가의 계량화, 프로세스의 일관성, 프로젝트의 정합성, 논리적 설득성으로 정의하였고, 디자인전문기업의 경쟁력요인을 기업의 신뢰도와 서비스 품질로 정의하였고, 연구모형을 설정하였다. 검증 결과 대부분의 가설은 채택되었으나, 평가의 계량화는 디자인전문기업의 서비스품질에 직접적인 영향을 미치지 않는 것으로 파악되었다.

  • The purpose of this research is to evaluate the biotope value in a metropolitan area after constructing the biotope evaluation model to develop biotope networking in the light of ecological landscape planning. In addition this study is to provide a basic frame of constructing the biotope networking system in the future with the evaluation results. The scope of this research is limited to high density residential area including some part of the forest adjacent to urban boundary. The results of the classified biotope in the research area have been turned out to be 24 patterns. According to the result of estimated nature value having the forth grade, three were forests combined with urban natural parks, schools near forests, and grasslands. There is a little place having first grade. We an deduce this fact that we have surveyed biotopes, having the minimum nature value and wider than children's park. As for the result of evaluated the structure, there were the forests of Seong-Dong, Meaho-Dong, and Kumho river, which is the forth grade. As for the evaluation of connection-function, the followings area were evaluated as the third grade-linear biotopes having highly valued and sustainable similarity - Seoul-Pusan Railroad, Dong-Daegu St., Kumho river, river basins. Bum대 park and a botanic park near Suesung lake, As for the evaluated the buffer-function, higly valued production biotopes, existing at a transition belt between he residential density areas, are Sawol-Dong, Meaho-Dong and Kumho river. When each of the indexes was evaluated, the core of the biotop contained most of natural biotopes. Large artificial biotopes were evaluated as an important biotopes, while small artificial biotopes were classified as a dot biotope. The future research on the concrete biotope networking construction, based upon performed evaluation in this research, should be conducted.

  • Hanwoo cattle are a unique and historical breed in Korea that have been genetically improved and maintained by the national evaluation and selection system. The aim of this study was to provide information that can help improve the accuracy of the estimated breeding values in Hanwoo cattle by showing the difference between the imputation reference chip platforms of genomic data and the scaling factor of the genetic relationship matrix (GRM). In this study, nine sets of data were compared that consisted of 3 reference platforms each with 3 different scaling factors (-0.5, 0 and 0.5). The evaluation was performed using MTG2.0 with nine different GRMs for the same number of genotyped animals, pedigree, and phenotype data. A five multi-trait model was used for the evaluation in this study which is the same model used in the national evaluation system. Our results show that the Hanwoo custom v1 platform is the best option for all traits, providing a mean accuracy improvement by 0.1 - 0.3%. In the case of the scaling factor, regardless of the imputation chip platform, a setting of -1 resulted in a better accuracy increased by 0.5 to 1.6% compared to the other scaling factors. In conclusion, this study revealed that Hanwoo custom v1 used as the imputation reference chip platform and a scaling factor of -0.5 can improve the accuracy of the estimated breeding value in the Hanwoo population. This information could help to improve the current evaluation system.

  • 사질지반에서 제안식에 의한 침하량 예측시 사용되는 주된 입력 물성치는 표준관입시험에 의한 N치이다. N치는 침하량의 예측치에 가장 큰 영향을 미치는 요소이기 때문에 침하량 예측시 적절한 N치의 산정이 이루어질 때 예측 침하량의 정확성이 확보된다. 그러나, N치가 50/30이상인 지반의 경우 N치는 30cm 관입시 타격수를 기록하는 것이 아니라 50회 타격시 롯드의 관입량을 기록하고 있다. 이러한 경우 침하량 예측시 N치를 50으로 사용할 경우 그 결과의 신뢰성이 결여된다. 이에 본 연구에서는 지반의 N치가 50/30이상인 경우 N치의 보정과 보정 N치를 이용한 Elastic Theory 예측치와 평판재하시험에 의한 실측치를 비교 검토하였다. 그 결과 보정 N치를 사용한 경우 보정하지 않은 N치를 사용한 경우에 비해 실측치에 대해 높은 정확성을 보였다. 또한, 순수 사질토에 대한 Elastic Theory의 적용성을 검토하였다.

  • This study examines whether there are differences in the evaluation of clothing products according to self-efficacy in purchasing clothes. A total of 300 surveys were distributed and 231 were used for analysis. The data were analyzed by regression and factor analysis. The results are as follows. First, there were significant differences in the product attributes considered according to self-efficacy in purchasing clothes. The consumers with high self-efficacy considered diverse product attributes comprehensively when making purchase decisions and had significantly higher score in perceived value and post-purchase satisfaction level than the consumers with low self-efficacy. Second, there were differences in the attributes of clothing products that effects perceived value according to self-efficacy in purchasing clothes. The attributes of 'clothes that I like' and 'necessary clothes' had a significant effect on perceived value for both consumers. The attributes of 'design that suits me' and 'inexpensive price' had significant effect on perceived value on consumers with high self-efficacy while the attributes of 'harmony with other clothes' had a significant effect on perceived value for consumers with low self-efficacy. Third, there were differences in product attributes and the perceived value that influenced post-purchase satisfaction level according to self-efficacy in purchasing clothes. The attributes of 'design that suits me' and perceived value had a direct effect on the post-purchase satisfaction level four consumers with a high self-efficacy. For the consumers with low self- efficacy, the attributes of 'clothes I like', 'necessary clothes', and 'design similar to that of usually purchased products' had a direct effect on post-purchase satisfaction level; however, the effect of perceived value was not found.
