This study gathered basic information on the development of Jiu-Jitsu uniforms suitable for players in Korea. Detailed data were collected between December 20th and December 30th, 2022 on 21 selected brands sold in online shopping malls. For each, information was recorded on the production country, product type, price, colors, material, and sizing system. A total of 612 datasets were analyzed using frequency analysis, cross-tabulation, and Chi-square tests. Jiu-Jitsu uniforms were classified as either standard or limited edition. Limited edition uniforms were more expensive than regular uniforms. International brands had a higher price range than domestic brands. The most commonly used colors for Jiu-Jitsu uniforms were the regulation colors associated with the sport: white, black, and blue. Domestic brands were more likely to use non-regulation colors than international brands. The material used for the top half of the uniform was predominantly pearl weave, while the bottom half was usually ripstop. International brands used a more diverse range of materials than domestic brands. The Jiu-Jitsu uniform sizing system incorporated a range of sizes between A00 and A6. While sizing designations differed according to the established sizing systems of different countries, the sizes remained the same, as did the range of sizes available. Where size guides were provided, height and weight were used to help the customer determine the appropriate size. The dimensions of each size varied between brands. Overall, we found that international brands offer a more diverse range of Jiu-Jitsu uniform designs than domestic brands.

Physical properties of composite resins such as strength, resistance to wear, discoloration, etc, depend on the degree of conversion of the resin components. The clinical behavior of restorative resins varies brand to brand. Part of this variation is associated with the filler and differences in the polymer matrix. The polymer matrix of resins may differ because the involved monomers are dissimilar and because of variation in the catalyst system. The purpose of this study was to evaluate the degree of conversion of the composite resins according to the depth of cure and light curing time. 7mm diameter cylindrical aluminum molds were filled with each of five different hybrid light curing composite resins(Z-100, Charisma, Herculite XRV, Prisma TPH, Veridonfil) on the thin resin films. The molds were 1mm, 2mm, 3mm, 4mm, and 5mm in depth to produce resin films of various heights. Each sample was given 20sec, 40sec, and 60sec illumination with a light source. The degree of conversion of carbon double bonds to single bonds in the resin films was examined by means of Fourier Transform Infrared Spectrometer. The results were obtained as follows; 1. There was difference in the degree of conversion among five light curing composite resins according to the depth of cure for 20sec, 40sec, and 60sec illumination with light source with statistical significance(P<0.05). 2. Five light curing composite resins show lower degree of conversion at surface of the resin than depth of 1mm. 3. The degree of conversion of five light curing composite resins was siginificantly reduced from the maximum for the resin film when the light passed through as little as 1mm of each composite. 4. The degree of conversion of five light curing composite resins decrease significantly at the depth of 4mm, and polymerization was not occured at the depth of 5mm except for Prisma TPH. 5. The degree of conversion of five light curing composite resins was increased with increased light curing time, and there was no significant differences in the degree of conversion above 4mm in Z-100, 3mm in Charisma, and at depth of 5mm in Herculite XRV and Veridonfil(P>0.05).

Rice quality must certainly be considered as one of the primary preference for consumers. On aspect concerns marketing, such attributes as appearance, physicochemical characteristics, and palatability of brand rice are very important. Therefore this study was carried out to observe the quality of commercial brand rice in Gyeongbuk Province, Korea from 2002 to 2004. In seasonal changes of mean air temperature from early July to middle August, it was lower in 2003 by $0.8{\sim}3.3^{\circ}C$ than that in normal year. Among the rice quality characteristics, the cv of percentage of head rice and palatability (Toyo value) were very low but those of chalky rice and protein content were very high during three years, and the same tendency was also observed among the brands. The average percentages of head rice were 92.5% in 2002, 89.9% in 2003 and 93.3% in 2004, respectively. On the contrary, the percentages of chalky rice were higher in 2003 as 4.9% than those in 2002 (3.9%) and in 2004 (2.8%). These results were caused by the abnormal meteorological conditions in 2003. Due to the higher protein content (8.0%) in 2003, the palatability was deteriorated to 71.0. However the protein content in 2004 was reduced to 7.0% and this result improved the palatability to 77.0.

Objectives: The market for bottled water is increasing steadily in South Korea. Bottled water contains several naturally occuring minerals, such as calcium, magnesium, sodium, and fluoride. Fluoride is proven to be effective in preventing dental caries. In South Korea, the maximum permissible concentration of fluoride is 2 ppm for bottled water and 1.5 ppm for tap water. The aim of this study was to investigate the fluoride content of different commercially available brands of bottled water in South Korea, and compare the measured fluoride concentration to the concentration written on the label of each brand of bottled water. Methods: Twenty-seven of the 59 different brands of bottled water produced in South Korea were investigated in this study. Three bottles of each brand were purchased from supermarkets, marts, and convenience stores in each region of Korea in August 2016. For each bottled water brand, the fluoride content was measured three times using a fluoride-ion selective electrode (Orion ionplus Fluoride Electrode 9609, Orion Research, USA). The calibration curve was generated using 0.2 and 2 ppm standard solutions, and confirmed using a 1 ppm standard solution. Results: The mean fluoride content of the 27 brands of bottled water was $0.374{\pm}0.332mg/L$ (range=0.040 to 1.172 mg/L). The fluoride content was labeled by the manufacturer, on each of the tested brands of bottled water. In eight brands, the labeled fluoride content differed from the experimental data. The minimum to maximum fluoride content measured from 10 brands showed a variation of 0.3 mg/L or more when compared to the labeled fluoride content. Conclusions: This study investigated the fluoride content of various brands of bottled water produced in South Korea and compared the measured fluoride levels with fluoride information on the bottle labels. To ensure that consumers are suitably informed regarding their exposure to fluoride, correct labelling of fluoride content in bottled water is important.

Rapid change of the era has caused change to consumption. New concept of consumer means not consumer who is simply provided a product, but a consumer who lays emphasis on value. That is to say, it indicates a consumer who values both on service and information as well as a product itself when they purchase. Therefore, the purpose of this research is to analyze the changes of POPs and objets at domestic and foreign fashion lingerie shops in different periods, and to encourage the effective introduction of POPs and objets for display at fashion lingerie shops in the future. I have used 100 pictures of 6 domestic brands and 80 of 6 foreign brands to analyze, and the periods were divided into 2000-2003, 2004-2007, and after 2008. The result of analyzing is as follows. First, give much information and great satisfaction to customers through the various types of POP, which convey the image and the concept of the products. If current POP was used only for sales, there ! should be various kinds and types of POPs to present not only basic information of products but also the value beyond it. Second, advance the products value by the presentation of diverse object. Furniture, fixtures, Lighting, Gift Box, Poster and mannequins should be used not to show simple props and presentation of product in the past, but to show brand images and Design concept of products.
Purpose - This paper's aim is to investigate whether or not gross profitability explains the cross-sectional variation of the stock returns in the Korean stock market. Gross profitability is an alternative profitability measure proposed by Novy-Marx in 2013 to predict cross-sectional variation of stock returns in the US. He shows that the gross profitability adds explanatory power to the Fama-French 3 factor model. Interestingly, gross profitability is negatively correlated with the book-to-market ratio. By confirming the gross profitability premium in the Korean stock market, we may provide some implications regarding the well-known value premium. In addition, our empirical results may provide opportunities for the fund distribution industry to promote brand new styles of funds. Research design, data, and methodology - For our empirical analysis, we collect monthly market prices of all the companies listed on the Korea Composite Stock Price Index (KOSPI) of the Korea Exchanges (KRX). Our sample period covers July1994 to December2014. The data from the company financial statementsare provided by the financial information company WISEfn. First, using Fama-Macbeth cross-sectional regression, we investigate the relation between gross profitability and stock return performance. For robustness in analyzing the performance of the gross profitability strategy, we consider value weighted portfolio returns as well as equally weighted portfolio returns. Next, using Fama-French 3 factor models, we examine whether or not the gross profitability strategy generates excess returns when firmsize and the book-to-market ratio are controlled. Finally, we analyze the effect of firm size and the book-to-market ratio on the gross profitability strategy. Results - First, through the Fama-MacBeth cross-sectional regression, we show that gross profitability has almost the same explanatory power as the book-to-market ratio in explaining the cross-sectional variation of the Korean stock market. Second, we find evidence that gross profitability is a statistically significant variable for explaining cross-sectional stock returns when the size and the value effect are controlled. Third, we show that gross profitability, which is positively correlated with stock returns and firm size, is negatively correlated with the book-to-market ratio. From the perspective of portfolio management, our results imply that since the gross profitability strategy is a distinctive growth strategy, value strategies can be improved by hedging with the gross profitability strategy. Conclusions - Our empirical results confirm the existence of a gross profitability premium in the Korean stock market. From the perspective of the fund distribution industry, the gross profitability portfolio is worthy of attention. Since the value strategy portfolio returns are negatively correlated with the gross profitability strategy portfolio returns, by mixing both portfolios, investors could be better off without additional risk. However, the profitable firms are dissimilar from the value firms (high book-to-market ratio firms); therefore, an alternative factor model including gross profitability may help us understand the economic implications of the well-known anomalies such as value premium, momentum, and low volatility. We reserve these topics for future research.

Objectives: This study compared the cyclic fatigue resistance of nickel-titanium (NiTi) files obtained in a conventional test using a simulated canal with a newly developed method that allows the application of constant fatigue load conditions. Materials and Methods: ProFile and K3 files of #25/.06, #30/.06, and #40/.04 were selected. Two types of testing devices were built to test their fatigue performance. The first (conventional) device prescribed curvature inside a simulated canal (C-test), the second new device exerted a constant load (L-test) whilst allowing any resulting curvature. Ten new instruments of each size and brand were tested with each device. The files were rotated until fracture and the number of cycles to failure (NCF) was determined. The NCF were subjected to one-way ANOVA and Duncan's post-hoc test for each method. Spearman's rank correlation coefficient was computed to examine any association between methods. Results: Spearman's rank correlation coefficient (${\rho}$ = -0.905) showed a significant negative correlation between methods. Groups with significant difference after the L-test divided into 4 clusters, whilst the C-test gave just 2 clusters. From the L-test, considering the negative correlation of NCF, K3 gave a significantly lower fatigue resistance than ProFile as in the C-test. K3 #30/.06 showed a lower fatigue resistance than K3 #25/.06, which was not found by the C-test. Variation in fatigue test methodology resulted in different cyclic fatigue resistance rankings for various NiTi files. Conclusions: The new methodology standardized the load during fatigue testing, allowing determination fatigue behavior under constant load conditions.
This study discussed the consumption and purchase behaviors of wine by hotel F&B employees based on cluster analysis. Consumption behavior was separated into two categories: place and frequency of drinking. Purchase behavior was divided into two as well: place and price of purchasing. In general, consumption behavior was more influenced by drinking place rather than price, with a wine bar being the most preferred place to drink. Further, purchase behavior was more dependent on the price than place, specifically mid-range priced wine. When selecting wine, "taste" was the most important quality considered for both consumption and purchase behaviors, followed by "price". In addition, "vintage" and "country/winery" were also considered important for consumption behavior. There was no further significant difference among selection attributes for wine quality in terms of purchase behavior. Overall satisfaction after wine consumption was 3.73. Frequency of drinking had a greater impact on overall satisfaction than drinking place. Overall satisfaction after wine purchasing was 3.72, and satisfaction level was greater when a wine was purchased at a wine bar rather than a general bar. With respect to country of origin, France, USA, Chile and Argentina wines all showed even variation among selection attributes for wine quality. However, Italian wine displayed a below average score under "vintage" and "bottle design", whereas Spanish wine did so under "brand". Lastly, Australian wine displayed the lowest scores for all selection attributes.
Due to desire for more variation from male consumers within the men's fashion market in Korea, there has been an ongoing development of departmentalization of fashion styles. The Generation-X man, in particular, is the most active member of our current day society, and will be the principal agent in the senior market from here on forth. Thus, this study categorized their preferred fashion styles, and will seek to analyze the behaviors related to the pursuit of clothing of the Generation-X man. The qualitative investigations of the Q-method as well as the quantitative investigation of the SPSS 12.0 were used in conjunction as the method of study. Additionally, images and types resulting from the preceding first-year study entitled "The Type and Characteristics of the Modern Men's Fashion Images" were utilized as part of the surveys. As a result of the Q-method, which was used to derive the preferred fashion styles of the Generation-X man, they were classified into three categories: the classic suit preferring 'conservative class type', the polished, comfortable style preferring 'modern sophisticated type', and the adventure and variety seeking 'uninhibited individualistic style'. After analyzing the factors which influence clothing preference behaviors of these men, a total of seven causes were drawn from the results, including: conservative indifference to fashion, others conscious pursuit of fashion, the aim to show off brand name products, high involvement in the aspect of design, pursuit of TPO, pursuit of self-image, and conformity to fashion. The elements that revealed differences in the behaviors in pursuing clothing within the preferred fashion style types of the Generation-X man included the conservative indifference to fashion, and others conscious pursuit of fashion, which therefore shows that rather than enjoying the fashion lifestyle, these men possess a more conservative disposition instead.
