This study has developed an interactive WBI to enhance learning effects on 'the Moon motion' for middle-school students. The quality of this examined by applying it to 20 science teachers and 49 middle school students 49. As a result, over 85% of the test subjects gave an affirmative response in the interest induction, the curiosity solving, and the degree of learning participation category, the degree of difficulty item. Response of the students with negative perception on science have changed positively(p<.05) after this WBI learning. In addition, we compared the learners' of knowledge prior and subsequent to 'the Moon motion'. As a result, it was found that the case of 'no concept' was enhanced more than the case having 'partly or ambiguously concept' for 'the Moon motion'.
The purpose of this study is that we regard the notion of reality that television viewers feel as presence, point out problem of measurement tool that appropriate for TV, clarify the subordinate concept of presence, and develop measurement tool that have reliability and validity. To achieve this, we paid attention to reality of television as a determinant of presence and tried to elicit proper subcategories. That is, we progressed two steps research that distinguished external characteristic and content of the media into sensible reality and cognitive reality, and develop measure item and verified statistical validity. We analyzed the second research result about measurement category of presence selected by first research and then we did Exploratory factor analysis and Confirmatory factor analysis. As a result, the first characteristic that make people experience presence is sensible reality, that is, it is the factor of sensible faithfullness, image faithfullness, and image reality as the form factor of the media. The second characteristic is cognitive reality. That is the factor of social reality, relational reality, and practical reality as the factor of media content. Synthesizing these subordinate factor, we can conceptualize presence experience as a reality of media form and content in HDTV viewing environment.
The development of mass media in the $20^{th}$ century has resulted in the rapid growth of the fashion industry. Fashion magazines like are performing the function of spreading new styles in addition to simple provision of fashion trend information. Therefore, the present study tracked the trend of changes in the cover models of USA during the last 10 years $(1997{\sim}2006)$, and examined qualitative and quantitative changes in the contents of USA for the last 20 years. According to the results, $50{\sim}75%$ of cover models were super models during the period from 1997 to 2006, but the percentages of fashion models and celebrities became similar to each other in 2001, and from 2002 to 2006 celebrities occupied around $75{\sim}92%$ of cover models. When the contents of USA were analyzed by category, columns that showed strength in 1986 but decreased gradually until 2006 were style suggestions(p<.001), fashion shooting on the theme of TPO and items(p<.05). Fashion columns that showed weakness in 1986 but increased through the 1990s and until 2006 were celebrity style(p<.05), item introductions(p<.001), shopping information(p<.001), designer interviews(p<.05) and fashion shooting on the theme of mood and celebrity(p<.05). These results suggested that the function of USA as a fashion magazine was mainly the provision of information on how to wear the new styles in 1986, but nowadays the contents have changed to information on what to buy. In addition, the results show that contents using highly popular celebrity increased rapidly in the 2000s.
Sustainable fashion & textile is more than eco fashion & textile with the concepts for the next generation's happiness, prosumer value, and community responsibility. This study considers methods to enhance fashion and textile industry sustainability in accordance to clothing types (material, product life and washing properties) and to investigate company strategies. Company strategies are of redesign with stock, volunteering & measuring trash amount, participation by evaluation stores, clerk environment education, hiring QC specialist and reinforcing partnerships. For the case of daily innerwear, throwing away and recycling is more efficient for the environment than laundering in the consumer use stage; subsequently, we recommend the use of polypropylene fiber (a cheap and an eco-friendly material) for this item that can be recycled and reformed after use. For the case of single layer clothing (such as sportswear, blouse or pants) we recommend the use of thermoplastic materials with welding or fuse assembling technology instead of a sewing method of seams as well as the recycle design that is simply melted and reformed into new clothing without an after use dissembling process. Secondhand use or resale is suitable for denim/jean items if the clothing has a storytelling or private history tag. Lastly, module-type jacket or coat shows the variety of styles with one clothing worn w/o collar or sleeve details and changed into vest/coat; in addition, it is possible to add or partly tear off some jacket/coat fibers of the felt material to reform it into a new design.
This is descripitive study conducted to identify educational needs of mothers of nephrotic syndrome patients and tie degree of nerses' educational performances perceived by mothers who look after mainly nephrotic syndrome patients. The study subjects were composed of 74 mothers of nephrotic syndrome patients whose children were hospitalized in 2 Pediatric wards of University Hospital in Seoul and 1 in Pen from June in 1996 to Januaryin 1997. A questionaire for this study was item Kikert type 5 point scale, developed on the basis of previous literature and researcher's clinical experience and the reliability of the used instruments was α=.97. The data analysis was done by SAS. t-test, and ANOVA were done to determine the effect of general characteristics of subjects on their educational needs. Pearson correlation was done to measure relations between general characterictics of subjects and their educational needs and Stepwise Multiple Regression was done to test a variable affecting educational needs. The results were as follows. 1. Mean score of educational needs of subjects was 137.06(Maximum 176). The score of the educational needs of home care was the highes, but the question numbers(of that category) are smaller than others. So, the educational need of the diagnosis art treatment was regarded as the highest in contents. 2. The mean score of nurses' educational performances was very low, 74.91(Maximum 176). Nurse's educational performances score in the diagnosis and treatment of the disease ranked as the highest Burt that score in the care during hoapitalization was the highest in contents as the educational needs was. 3. The number of children excepting the patient (r²=.215289. p=.006) and the age of patient(r²=.23770, p=.001) were emerged as important variables affecting the degree of mother's educational need.
Purpose - This study investigates the purchase pattern relating to soybean products in Korea. Specifically, the effect of branding based on a regional name was analyzed in terms of consumer purchase frequencies. The primary purpose of this study is to understand why family characteristics affect product selection for a regional brand in the soybean food category. Research design, data, and methodology - We used data collected by the Rural Development Administration (RDA) of Korea. The RDA has monitored agricultural food consumers for years in order to obtain purchase records. Panel participants live in regions near the capital city of Seoul, Korea. Examining data from January 2010 to May 2016, 667 families were selected for analysis. The final data set was 1,335,402. Each purchase item by each individual family was aggregated to a countable weekly observation. To analyze the data set quantitatively, zero-inflation regression was adopted, which was appropriate to avoid biases from overly dispersed observations. Results - We hypothesized the effects of regional branding from the viewpoint of the family characteristics. The first hypothesis was that the number of children would be positively associated with the purchase of a regional brand of soybean products. The result strongly supported this hypothesis. The second hypothesis was that the number of family members would be negatively associated with the purchase of the soybean products of a regional brand. Based on empirical analysis, we concluded that this hypothesis was partially supported. The third hypothesis was the presence of an interaction effect between the number of children and the family size, which was supported by the results. As a supplementary analysis, we also tested mean-variance differences in terms of categories and regional branding with corporate branding. Conclusion - The results of this study provide insights for regional branding strategies in agricultural food management. This study appears to be one of the seminal studies trying to analyze purchase patterns from longitudinal observations. In addition, this study adopted variables characterizing family lifestyle. This study confirmed that children and family size should be considered when soybean product brands are introduced.

This study investigates the suitability of outdoor wear among female trekkers in their twenties or thirties and provides data for developing outdoor wear more suitable for young females. Recently climbing has gained popularity as a leisure activity to enjoy the beauty of nature that increases physical and mental stamina. A survey was conducted on 304 female consumers in their twenties and thirties who enjoyed climbing in order to investigate the suitability of outdoor wear among young female consumers. The questionnaire covered the subjects' demographic information, duration and goal of climbing, purchase and suitability of outdoor wear, and preferred design for outdoor wear. As for the yearly situations, when they utilized outdoor wear, the biggest number of respondents chose "autumn" as the season for climbing. Most of the respondents were non-professional trekkers who enjoyed climbing as a hobby or for health. As for the size, the upper garment was 90 and 85 in the order, and the lower garment was 70 and 67 in the order. The pants were the most common item they owned, followed by round T-shirts, windbreaker jackets, zipup T-shirts, and waterproof jackets. They mentioned moisture absorption and dry fabric breathability as the basic functions required of outdoor wear. The subjects displayed a preference for partial details under the design category. They most preferred the hood-type jacket with a detachable stand collar, the sleeve hem with a partial rubber band and velcro strap, a T-shirt with a stand color and zipper, the waist fit with proper room, pants with a partial rubber band waist, and straight silhouette pants.
In this study, we try to quantify resident's conflict by rural development project based on previous researches about community capacities required for residents and social networks in rural village for suggesting efficient project model. we analyzed conflict elements in six category such as 'conflict in residents', 'conflict in residents and leaders', 'conflict in leaders', 'conflict in villages', 'conflict in development fund', 'conflict in village by common income project'. These results also analyzed by personal background(age, role, education, income) of respondent in questionary survey. Results show that 'conflict in residents and leaders', 'conflict in leaders', 'conflict in development fund' are perceived differently by age, role, education, and income in 5% significance level. Especially, relatively young age(below 40 years old) expressed clearly about conflict and high scored in item of 'residents and leaders'. Regression model show statistical significance(F=39.807, P=0.000) in influence relation analysis of conflict, network, leadership, and project fund. In this model, network ${\beta}=-0.237$, leadership ${\beta}=-0.375$, project fund ${\beta}=-0.000$ show network and leadership have negative relation to conflict but project fund is difficult to find relation with conflict. In this study, we defined social vulnerability using conflict, network, and leadership and verified the vulnerability of rural village applying regional community capacity in analysis results; vulnerability increased by the size of region and show inverse correlation to future vision of residents.
In procurement auctions, auction frequency and transaction volume per auction have been analyzed as important factors in determining auction performance. However, there is no empirical study on the effect of auction frequency and transaction volume in procurement auction. Current studies mainly focus on bidder behavior analysis and new system design in procurement auction. In the study, we analyze the effect of two factors on relative winning price empirically by using real auction data from MRO procurement outsourcing company in Korea. From the results, we find the winning price is lower when the frequency of auction with same item category is lower. The low frequency of auctions means participating bidders have limited information of previous auctions and they bid their best price to win the current auction due to less opportunity of reopening the auction in near future. The larger purchase amounts of MRO items didn’t results in lower winning price, contrary to our hypothesis. The possible reason is that the price of MRO items already reflects the economy of scales and the increased volume per auction do not cause the further discount of MRO items from the auction.

Background: The use of therapeutic materials based on new health technology has increased in recent years in the field of medicine, raising concerns for medical practitioners regarding increased spending on the new therapeutic materials amid the rapid population ageing and increase of chronic diseases in Korea. While therapeutic materials have significant importance in the health care system, they have not been given appropriate attention in the academic world of Korea. The purpose of this study is to identify factors that affect the growth of expenditure on therapeutic materials and to derive implications for an effective management considering the diversity of therapeutic materials. Methods: Using the claims data of the National Health Insurance Services, specific utilization patterns of groups of therapeutic materials in the middle classification level of Health Insurance Review and Assessment Service from 2007 to 2014 were analyzed. Four categories (J5083: drug eluting coronary stent, D0302: nonmetallic anchor, K6014: gauze, K6023: gauze) that exhibit unique patterns with respect to price and volume were selected. Then, decomposition analysis was performed to identify the largest contributor to the spending growth by dividing the products into existing, new, and abandoned products for the period between 2010 and 2013. Results: The effect of new products had larger impact on spending growth than the effect of core items in drug eluting coronary stent (J5083) and nonmetallic anchor (D0302). In addition, existing products in general included items priced relatively lower when compared with another item manufactured by the same company. In the gauze category, however, existing products had the largest impact on expenditure and the effect of volume was greater than that in other categories. Conclusion: This study provides evidence that appropriate management measures classified by the characteristics of therapeutic materials are required for therapeutic materials pricing and reassessment in Korea.
