Many brands are attempting to use consumers as a part of their marketing strategies, due to the fashion industry's sensitive response to consumers' reaction. In addition, due to the popularity of e-WOM(electronic Word-Of-Mouth), fashion brands are highly sensitive to their supporters' online reviews. Amid this background, the main objectives of this study are as follows: 1) to analyze the effect of online reviews' attributes and valences on forming an impression about a fashion brand; 2) to examine the online re-WOM(word-of-mouth) effect of online reviews by fashion brand supporters on brand attitude; and 3) to measure the moderating effect of fashion involvement in online re-WOM intention. In order to verify the research model and to test the proposed hypotheses, a 2 (utilitarian vs. hedonic review attributes) by 2 (positive vs. negative review valences) model is constructed and gathers 215 respondents. The results demonstrate that consumers form the highest reliable impression based on utilitarian and negative online reviews. However, there is no relationship between the types of online reviews and the formation of a favorable impression. Findings also reveal that the impression formed by online reviews has a positive effect on re-WOM intention, contributing to brand attitude. In addition, the hypothesis about the moderating effect produced by fashion involvement on re-WOM is supported. In conclusion, these results suggest that online reviews by fashion brand supporters have a powerful effect on forming a consumer's impression towards a fashion brand, affecting re-WOM intention and brand attitude.

Diabetes represents a serious health problem. In the diabetic state, alterations in metabolism, increased susceptibility to infections and immunological changes occur. The suppression of the immune response has been identified as a relevant factor that contributes to the increase in the rate of infections in these patients. At the same time, breast cancer is the most frequent malignant tumor in women. The molecular and cellular mechanisms underlying cancer development have revealed that immune cells functionally regulate epithelial cancer development and progression. Breastfeeding has been hypothesized to reduce the risk of breast cancer. However, early systematic reviews have not yielded consistent findings for this association. The demand for human milk is increasing due to the promotion and consumer acceptance of the health benefits of consuming a natural product rich in bioactive components. However, due to changes in glucose metabolism, the components of the milk from diabetic women are modified depending on the time of evaluation. In this literature review, we summarize important new findings revealing the paradoxical role of breastfeeding in preventing the onset of breast cancer in diabetic mothers. We hypothesized that the milk component production in diabetic mothers is affected by changes in glucose metabolism. Therefore, adequate maternal glycemic control and an adequate duration of breastfeeding for diabetic mothers are crucial to ensure that the immunity components are able to confer protection against breast cancer.

It is critical to forecast the maximum daily and monthly demand for power with as little error as possible for our industry and national economy. In general, long-term forecasting of power demand has been studied from both the consumer's perspective and an econometrics model in the form of a generalized linear model with predictors. Time series techniques are used for short-term forecasting with no predictors as predictors must be predicted prior to forecasting response variables and containing estimation errors during this process is inevitable. In previous researches, seasonal exponential smoothing method, SARMA (Seasonal Auto Regressive Moving Average) with consideration to weekly pattern Neuron-Fuzzy model, SVR (Support Vector Regression) model with predictors explored through machine learning, and K-means clustering technique in the various approaches have been applied to short-term power supply forecasting. In this paper, SARMA and intervention model are fitted to forecast the maximum power load daily, weekly, and monthly by using the empirical data from 2011 through 2013. $ARMA(2,\;1,\;2)(1,\;1,\;1)_7$ and $ARMA(0,\;1,\;1)(1,\;1,\;0)_{12}$ are fitted respectively to the daily and monthly power demand, but the weekly power demand is not fitted by AREA because of unit root series. In our fitted intervention model, the factors of long holidays, summer and winter are significant in the form of indicator function. The SARMA with MAPE (Mean Absolute Percentage Error) of 2.45% and intervention model with MAPE of 2.44% are more efficient than the present seasonal exponential smoothing with MAPE of about 4%. Although the dynamic repression model with the predictors of humidity, temperature, and seasonal dummies was applied to foretaste the daily power demand, it lead to a high MAPE of 3.5% even though it has estimation error of predictors.

Objective: Previous studies suggested the potential influence of YouTube videos regarding dentistry on the mass population. However, there was not any clear investigation for Korean population. We aimed to systemically analyze the type of the dentistry-related videos uploaded on YouTube Korea and the accounts used for uploading, and to assess their effect on the view count of the content. Methods: Classification, type of the accounts, and view count of the videos listed by the keyword 'dentistry' were analyzed, which were uploaded on YouTube Korea platform from September 2017 to April 2019. Kruskal-Wallis test with post hoc analysis was used to assess the effect of the classification of the videos and the type of accounts on the view count. Results: 1.026 videos were enrolled to the analysis. Primary classification of the videos was information/education, advertisement, life, news, child contents, autonomous sensory meridian response, broadcast, cartoon/game, humor, and music. Secondary classification of the videos was dental experience, advertisement, role-playing, information/education., humor, cartoon/game, child contents, life, and broadcast. Type of the accounts was dentistry associates, general public, media company, and government office (sorted by frequency). Subject of the most videos (93.6%) was general public. There was statistically significance in the view count of the videos according to the primary and secondary classifications, the account used for uploading, and target subject of the videos. Conclusion: Dentists and their associates should recognize the importance of YouTube platform and try to monitor and intervene the dentistry-related contents, considering its huge impact on the general public.

Purpose - The purpose of this study is to examine the effect of basic value satisfaction on service quality evaluation and customer loyalty and the moderating effect of Bargain-proneness in this process. Specifically, I analyzed the influence of basic value satisfaction, the mediating effect of service quality evaluation, and the moderated mediation effect of Bargain-proneness. Research design, data, and methodology - Data collection for this study was conducted for adults over 18 years of age with shopping experiences in traditional market within a month around the traditional market in the metropolitan area. A total of 250 questionnaire response data was obtained. Hypotheses were tested using SPSS. The PROCESS macro method was used to verify the mediating effect of the service quality evaluation on the relationship between basic value satisfaction and customer loyalty. Hierarchical regression analysis was performed to analyze the moderated mediation effect of the bargain-proneness tendency. Results - Empirical results showed that the basic value satisfaction affected service quality evaluation and customer loyalty. Specifically, it has been found that it directly affects customer loyalty and indirectly influences through service quality evaluation. The moderated mediation effect of the bargain-proneness tendency in the process of basic value satisfaction affecting customer loyalty through service quality evaluation has been verified. In other words, the higher the bargain-proneness tendency, the more influence the basic value satisfaction has on the favorable service quality evaluation. Conclusions - This study contributed to the distribution literature in that it attempted a new empirical study considering the variable 'bargain-proneness tendency', which had not received much academic attention in the past. Furthermore, this study contributed academically in that it presented important moderating variables that should be paid attention in the field of distribution studies. In this study, bargain-proneness was used with a focus on traditional markets, but this variable could play an significant role in future offline distribution studies that should pay attention to meet hedonic needs of shopping. These results suggested that traditional market practitioners should focus on the basic value and that the bargain-prone consumer segment should be considered as a target.

As Multi-National Enterprises expanded their investments to foreign countries, numerous controversies and disputes arose from their negative impacts, such as violations of human rights and damage to the environment of the host countries. In response, International Organizations such as the OECD have considered various ways to prevent these negative impacts and search for more efficient dispute resolution methods. It is recognized that the OECD Guideline is one of the tools they created for this purpose. The OECD Guideline is contrastable from Corporate Social Responsibility (CSR) initiatives which are regarded as a corporation's charity activities apart from their core business functions. However, Responsible Business Conduct (RBC) like the OECD Guideline can be understood as a concept moving forward from CSR, due to its requirements that corporations carry out their duties in a responsible manner within the field of their core business, such as tax, global supply chain or consumer protection. RBC which is binding in nature, has even been implemented through legislation in developed countries such as the USA, France, Switzerland, and the UK. The discussion in Korea, however, has not reached that level. Discussions for legislation center singularly on CSR efforts, with a dialogue only recently forming around the topic of legislation concerning RBC. Small and medium sized enterprises (SMEs) who lack certain financial and other resources to adequately develop RBC initiatives may find this more obstacles to implementation through legislated RBC, than if it were presented in Korea through other means. It's necessary to admit that RBC is a critical issue in international business. However, time is required to consider its application directly to SMEs.

Background: Cooking temperature and consequently doneness of beef muscles are most important for the palatability and consumer acceptability. Current study assessed the response of mechanical texture of Hanwoo muscles as a function of cooking temperature at different ageing days. Six muscles (Psoas major (PM), Longissimus thoracics (LT), Gluteus medius (GM), Semimembranosus (SM), Biceps femoris (BF) and Triceps brachii (TB)) were collected from each 10 Hanwoo steers. Warner-Bratzler WB-shear force (WBSF) and texture profile analysis (TPA) texture profiles were determined after 3 or 21 days of chiller, and randomly assigned to four groups; non-cooked, cooked at 55, 70 or $85^{\circ}C$. Results: Toughness of WBSF and TPA hardness of Hanwoo muscles were presence in the order of LT = PM = GM = SM < BF = TB (p < 0.001) for non-cooked raw muscle, and PM < LT = GM = SM < TB=BF (p < 0.001) for cooked meat aged for 3 days. WBSF linearly increased in 3 days aged meats after cooked at a higher temperature (P < 0.05). On the other hand, toughening of the muscles were significantly (P < 0.05) differed at various temperature when muscles were aged for 21 days. WBSF of PM and LT muscles were significantly increased at a higher cooking temperature, while other muscles (i.e., GM, SM, BF, TB) showed the lowest values at $70^{\circ}C$. In the case of TPA hardness, the effect of cooking temperature was very less in the toughness of the muscle (P > 0.05). Conclusion: Taken together, these findings clearly showed that the toughness of the muscle highly depends and varies upon the temperature and ageing of the muscle. Moreover, the effect of cooking temperature was very limited on aged muscles. The results mirror the importance of cooking temperature for objective measurements which ultimately estimate sensory tenderness and other quality traits.
