The aim of this study was to determine the optimum amount of apricot seed powder to add to rice flour in oder to prepare Sulgidduk (traditional rice cakes). As the apricot seed powder level of the Sulgidduk increased, the moisture contents of the samples decreased (40.30~43.46%), and the color of L- and a-values also decreased, while the b-value increased. According to instrumental test results, hardness, springiness, gumminess, chewiness and adhesiveness were all highest in the 0% apricot seed powder sample. The cohesiveness of samples did not show a conclusive relationship with the level of apricot seed powder present. In sensory evaluation results, the 3% and 6% samples received high overall acceptability scores. In conclusion, based on both sensory and instrumental testing, the optimal Sulgidduk mixture consisted of 3~6% apricot seed powder added to rice flour.

이 논문은 참깨다식을 만들었을 때 실용상 이용에 지장이 없는 저장기간이 얼마나 되는지를 알고자 실험한 것으로 얻어진 결과는 아래와 같다. 1. 탄력성과 응집력은 30일 저장기간 동안 뚜렷한 변화가 없었다. 2. 씹힘성은 10일 저장 후는 처음보다 커졌으나 저장 20일과 30일 사이에는 차이가 없었다. 3. 검성은 저장기간이 경과됨에 따라 증가하였다. 4. 부착성은 저장기간이 길수록 감소하였고, 특히 30일 저장 후에는 감소폭이 컸다. 5. 저장기간 경과에 따라 경도는 뚜렷이 증가되었다.

The physico-chemical characteristics by bleaching treatments were assessed by several instrumental analyses such as surface morphology, chemical structural change, color change as well as tensile strength. The change of morphological characteristic was observed through scanning electron microscope(SEM). The observation of the fine structure on hair surface by SEM showed the bleached hair had much damaged to hair cuticle, and some of cuticle surface were worn away. To investigate the chemical structural changes in hair keratin, the cross-sections of hair samples were directly analysed using Fourier transform infrared microspectroscopy(FT-IRM). The results showed the cysteic acid S=O band intensity was distinctively increased by performing the bleaching treatment. The cleavage of cystine was appeared to proceed primarily through the sulfur-sulfur (-S-S-) fission whereby cysteic acid was formed as a principal oxidation products. The distribution of amide I band in hair keratin was determined by attenuated total reflectance(ATR) FT-IR mapping image. The results showed that the outer side of hair cortex was more damaged than the inner side of the hair cortex. Also, during chemical bleaching of the hair with alkaline peroxide, the hair was turned to reddish yellow due to the oxidative degradation of eumelanin. This means the eumelanin is more unstable than pheomelanin in chemical oxidation. With bleaching, the tensile strength was also reduced as a results of the chemical oxidation.

Apparel Quality was one of the most important elements to evaluate the reputations of companies and products which affect the consumer's purchasing behavior. From researches on apparel quality, there was no common concept of quality as well as no common dimensions. The purposes of this study were to identify apparel quality concept and to classify the multi-dimensional concept of apparel quality. The research was carried out in theoretical as well as empirical studies. The theoretical study was conducted to find out apparel quality concept and divide apparel quality concept into four dimensions groups. The empirical study followed the theoretical study to confirm the multi-dimensional concept of apparel quality. The empirical study was investigated that the questionnaire was administered to 634 housewives in Seoul, Kwangju, and Busan during the fall of 1996. The data were analysed by LISREL analysis. This study identified that apparel quality was characteristics of consumer's desires for apparel. The results of the theoretical study verified that apparel quality concept was organized into four different dimensions: physical attribute, physical function, instrumental performance, and expressive performance.

This study investigated country-of-origin effects by comparatively analyzing consumer attitude toward country-of-origin of imported apparel according to apparel product attributes. Fishbein attitude model was used. The effects of consumer characteristics such as attitude of consumers toward general imported apparel and demorgraphic variables on consumer attitude toward country-of-origin were also identified. Italy, U.S.A, Japan, Hong Kong, Korea were used as country of origin. Data were obtained from male and female subjects(total 570) aged mostly 20's. Statistical analysis showed: 1) Apparel product attributes were classified into 3 factors, expressive, instrumental and brand, which are the order of importance for purchasing. 2) Consumer indicated more favorable attitude toward 'made in 'Italy' nd made in 'Korea' in each attribute factor. 'Made in Korea' roducts were evaluated highest in expressive attribute factor but less favored than 'made in Italy' n brand attribute factor. 'Made in U.S.A and made in Japan' were evaluated favorable in instrumental factor, whereas 'made in Hong Kong' had the least favorable attitude in every attribute factor. 3) The uniqueness and good quality of imported apparel appeared to be the most strong variable in predicting consumer attitude toward each country-of-origin. 4) The attitude toward country of origin was different according to sex and age.

This study has investigated a scientific approach to the manufacture of Yackwa, made by different frying conditions and has assessed texture characteristics through sensory evaluation and instrumental test. A standard Yackwa was made by frying at 150$^{\circ}C$ for 8 minutes and then soaking for 10 minutes in the newly developed syrup whose viscosity and sweetness were similar to expensive honey. The mixing ratio of the developed syrup was corn syrup: sugar: dextrose=32 : 1.5 : 1 (by weight), and me syrup was double-boned in a water bath for 20 minutes and men cooled to 25 C. As me results of sensory evaluation and instrumental test for Yackwa made by various frying conditions, the lower the frying temperature or me longer the frying time was the higher values of hardness and fracturability, while adhesiveness was the lower in almost all conditions. In the sensory evaluation of Yackwa with the similar outer color, mere were significant differences in me inner color, Crispiness and levels of rising and cracking.

The purpose of this study was to investigate conceptual representations of the self in Korean culture by analyzing normative conception of the self present in Sohak. The method of this study was the historical method and the material for analysis is 'Reverencing for the Self of Sohak, which was the textbook for childhood education and contained normative tasks that the society of the Chosen Dynasty period held for what people should do in their lives. According to the analysis, the Chosen Dynasty had interdependent conception of the self, which had strong emphasis on connected relationships, especially between self and parents, and regarded respect, rightness, and politeness as important attributes of the self, and expected reciprocal exchange of mutual support in social roles. Also, there were many instrumental and terminal goals in normative expectations of the self, which were toward harmonious interdependent relationships. Finally, the attributes of the self that were thought of as positive characteristics served collective interests rather than individualistic ones. In addition, the society of the Chosen dynasty regarded socially disengaged emotion such as pride, anger, and pleasure as negative ones.

The selection and effective utilization of peak-fitting software for conventional gamma-ray spectrum analysis is significant for accurate determination of the mass fraction of elements, particularly in complex peak regions. Majority of the peak-fitting programs can derive similar peak characteristics for singlet peaks, but very few programs can deconvolute multi-peaks in a complex region. The deconvolution of multi-peaks requires special peak-fitting functions, such as left and right-skew distributions. In the this study, 843.76 keV (²⁷Mg) peak area from the complex region (840 keV-850 keV) determined and compared using four different peak-fitting programs, namely, GammaVision, Genie2000, HyperLab, and HyperGam. The 843.76 keV peak interfered with 841.63 keV (^152mEu) and 846.81 keV (⁵⁶Mn). The total Mg concentration was determined through k₀-instrumental neutron activation analysis by applying the isotopic interference correction factor ²⁷Al(n,p)²⁷Mg through the simultaneous determination of Al concentration. HyperLab and HyperGam peak-fitting programs reported consistent peak areas, and resultant concentrations agreed with the certified values of matrix-certified reference materials.
