  • The purpose of this study is not to look at the history of traditional accessories or the characteristics of their shapes but to discern imitations £Tom authentic items by exploring imitations of traditional accessories-- many of which were made in the late 20th century -- from private museums and university museums in order to help scholars assess relics. Among many kinds of accessories in the Joseon dynasty, only norigae, one of the representative accessories, and women hair ornaments are selected for this study since many of the relics have been recovered to date. Given this, this study will consider firstly the general history of norigae and women's hair ornaments, and secondly, prove several examples as relics from the late 20th century while they are marked as relics from the Joseon dynasty by comparing authentic items. Thirdly, among the imitations of the late 20th century, this study will find those so-called "original" imitations whose production origins are unidentified Fourthly, this study will explore the imitations, which were influenced by the influx of items and materials from China. It is important to discern low-quality relics as well as to correct the production time. Some producers exercised their creativity and made relics non-native to Korea. These relics shouldn't be presented at international exhibitions. Restored relics should be noted so and their quality should be equal to the authentic items. It is suggested that relics without the identity and quality of native Korean relics not baffle cultural interchanges and enhance national glory.

  • The purpose of this study was to develop a skirt pattern drafting method for korean women between the ages of $18\~24$ on the basis of their physical charcteristics which differs from those of other races in its size and figure. The study procedures and results were as follows; 1. Ten types of convantional skirt patterns were collected and compared to determine the essential measuring items for skirt construction, and to discover what problems are involved. 2. Fourteen items of KIST measurement data were analysed for correlation coefficients, to establish representative items and independent ones. 3. Front waist length and back waist length were additionally measured for supplementary data. 4. A new skirt drafting method was developed based on the results of the pattern comparison and the data analysis. 5. A sensory evaluation was applied to evaluate the new method comparing it with the most widely accepted conventional pattern. An original rating scale was developed for the evaluation and an expert panel consisting of five members judged each shell from 12 subjects by random selection. According to a statistical analysis of the result of the 17 items on the rating scale, 14 items showed significant differences (${\alpha}\leqq$0.01 or ${\alpha}\leqq$0.05) between the two, with the new pattern having better fit. The new pattern drafting method proved to be superior to the conventional one especially in the fitness at the back hip, dart length, side seam balance, and the ease for daily activities.

  • The summarized findings resulted from experiments and investigation are suggested as follows ; The analysis of measurements on the lower limb movements : For this experimentation, data was collected from three hundred and eighty female, age 19 to 23, who answered five lower limb movements(M1~M5). The statistics show that the order of the expansion ratio is gluteal area-length/knee-girth/back-line/knee-depth/thigh-depth/hip-girth, from the highest to the lowest in all movements. When comparing the correlation coefficient of the measurements, the values of the correlation coefficient of the height and the length items are very low, but those of the girth, the breadth, and the depth items are relatively high and those of the waist and the hip items are highest. For more sophisticated analysis, the factor analysis was conducted on the lower limb movements. Four factors were classified on the factor load by the "varimax rotation" method. Each movement shows the most important factor differently, as follows ; the most important factor in M1 is "the shape factor of lower limb below hip-line", that in M2 is "the cross-sectional shape factor", that in M3 is "the size factor of abdominal and loins region", and those in M4 and M5 accord with the interpretation of M3. When the investigation of the estimated function was conducted, in the selectional case of representative items on the slacks construction, it found that it would be better to add abdomen and thigh items as important considerations to waist girth, hip girth and crotch length.

  • The purpose of this study was to develop a reliable and valid instrument to measure hope for cancer patients in Korea. This Hope Scale(Kim & Lee Hope Scale ; KLHS ) was developed based on not only critical universal attributes explaining both basic hope (generalized hope) and specific hope but also particular characteristics varing from culture and situation, which were revealed in a comprehensive review of the literature. Initially 60 items were generated from three sources : 36 items from the Q-sample used in the Kim's study, 1992, 21 representative items(statements) from the rest Q-population of the above study, 3 items related to the newly discovered category in the new qualitative study using 10 open ended question(death and dying) from the new qualitative study on the 20 cancer patients. At first 3 items were eliminated by the critique of the content validity experts, who were high experienced nurse, nursing professors. And then 4 items were eliminated in consideration of corrected item total correlation coefficiency, theoretical framework of this study. After that, 14 items were eliminated in comparing two or three items identified with the same meaning in each factor by this research team with factor loading and communality. This Hope Scale was finally constructed with 39 items. Psychometric evaluation was done on 492 adults(104 cancer patients, 388 adults who imagined who were cancer patients ranging from 18 to 76 years old. The results revealed high internal consistency Alpha coefficiency of .9351. Princial Component Factor Analysis with Varimax Rotation resulted in 8 factors with more than 1.0 of Eigenvalue. Referring to Eigenvalues, percent of variances(>60%), reproduced correlation matrix, and our theoretical framework, we decided the eight factors were the best1 solution to represent hope dimensions sufficiently. The eight factors were "confidence in possibility of cure", "sense of internal satisfaction", "being in communion", "meaning of life", "Korean hope perspectives", "belief in god", "self confidence", "self-worth". Among these factors, "confidence in possibility of cure", "sense of internal satisfaction", "Korean hope perspectives" were identified as different hope dimensions from those of Nowotny Hope Scale and Herth Hope Scale. There was significant negative correlation of r=-.4736 between this hope scale and Beck Hopelessness Scale (BHS), and significant positive correlation of r=.3685 between this hope scale and Life Orientation Test (LOT) which indicate convergent and discriminant validity. The range of hope scores was from 71 to 244, with a mean of 171.97(SD=28.16).

  • The methods used in this study included investigation of media facades used for landmarks in downtown areas in previous studies, visits to these areas, and recording of media facades. The changes in the colors or the size of buildings were analyzed among the recorded cases and 12 of these cases were selected for further study. The sensibility preference of the media facades was evaluated by sorting the 12 kinds of media facades, and providing them as materials to a group of 60 participants (40 undergraduate and 20 graduate students majoring in architecture and design) consisting of an equal proportion of males and females. This study addressed the following four_stage questions: 1) Five questions of recognition evaluation about media facades and the cognitive evaluation items of emotional vocabulary and color preference in each research case; 2) sensibility preference items regarding the media facade color design; and 3) design evaluation items of the media facades; 4) Video clips and still images were recorded from a middle distance at 7p.m to 11p.m. in central New York, Singapore, Seoul, and Beijing. The participants looked at the changes in colors through the video clips in each case and evaluated their preferences through 23 pairs of emotional vocabulary items using system dynamics. Construction of an emotional vocabulary followed, based on previous studies about media facades and color design. To evaluate the sensibility preference and the perceived representative colors of the media facade, this study suggests new emotional responses that depended on the color emotional vocabulary of light in the LED lighting technical evaluation methodology. A media facade with a moving change of colors, unlike a fixed landscape color design, suggests a new communication method based on architectural factors. New architectural color coordination can be presented for urban landscapes at night. Designs that factor in the pedestrians' emotional vocabulary or preference should take precedence over the use of high luminance and various colors.

  • Decreasing response rates to traditional survey methods, like face-to-face and telephone interviews, have led survey practitioners around the world to seek new ways of conducting surveys in recent years." The COVID-19 pandemic exacerbated this problem because it made conducting face-to-face interviews even more difficult than before. For example, it made conducting face-to-face surveys infeasible in 2020 in South Korea, and so the Korean Academic Multimode Open Survey (KAMOS) was unable to conduct a planned face-to-face survey to recruit new panel members. The entire 8,514-member panel, established via two-stage probability-based sampling from 2016 to 2019, was invited to take three online/telephone surveys in 2020. Of these panel members, 1,352 responded to at least one survey in 2020. To test to what extent the panel remained representative of the adult South Korean population, we compared the two groups of panel members: those who responded to at least one survey in 2020 and those who did not. After weighting both groups on the basis of age, sex, and geographical area, we analyzed their responses to some of the questions that were asked during multiple rounds of the face-to-face panel-recruiting interviews. Using Cohen's d for survey items that could be analyzed numerically and Cramér's V for categorical items, we were able to conclude that the respondents to the 2020 surveys were equivalent to the non-respondents in terms of both demographics and in the answers they originally gave to substantive questions on a variety of topics related to social science or public opinion research, including questions about quality of life, societal issue, and politics (Cohen's d items <0.2, 95% CI; Cramér's V items <0.1, 95% CI). This analysis may provide a model for others who wish to test the continued representativeness of their panel or who would like to use a different survey mode or change some other aspect of their methodology and test whether it is equivalent to their former methodology. Our success in building a panel that retained its representativeness may be useful to those in other countries where face-to-face surveys had previously been the norm but are becoming increasingly difficult to conduct.

  • BACKGROUND/OBJECTIVES: Food literacy (FL) is a crucial skill for selecting sustainable and healthy food options, necessitating the identification of vulnerable groups in the community using valid measurement tools. Identifying weak domains in FL is essential for enhancing the overall FL. This study examined the FL levels of Seoul citizens based on their sociodemographic characteristics and assessed the relationship between FL, food intake, and weight status. SUBJECTS/METHODS: This study utilized the data from the Seoul Food Survey, a cross-sectional study employing representative samples of Seoul citizens. Data collection occurred from September to October 2021, with 4,039 citizens aged 18 yrs and above participating in face-to-face surveys. Thirty-three FL items were assessed, comprising 14 items in the nutrition and safety (NS) domain, eight items in the cultural and relational (CR) domain, and 11 items in the socio-ecological (SE) domain. In addition, data on food intake sufficiency and obesity status were collected. The descriptive statistics, t-tests, analysis of variance, and logistic regression analysis were used for analysis. RESULTS: Men, students, young adults, older citizens, and people experiencing food insecurity had the lowest scores for all the FL domains. The highest quartile group of NS scores had a higher probability of consuming adequate servings of vegetables and fruits, with significant linear trends observed (P for trend < 0.05). In all three FL domains, the odds ratio for obesity was significantly lower in the groups with high FL scores (P < 0.05). CONCLUSIONS: A close relationship was observed between low FL, obesity, and food intake, even after controlling for other covariates. Vulnerable groups with low FL were also identified. Therefore, it is essential to develop programs to improve FL and the health and well-being of these groups.
