Women starts to make up after high school graduation. They have low economic power. But they select cosmetics by themselves and have high demand. Therefore, they can be major customers of low-priced cosmetics and it can be regarded as independent cosmetics market. Thus, this study analyzes the purchasing propensity of lowpriced cosmetics in female undergraduates, who are main targets of low-priced cosmetics, satisfies the more customers desire through further segmenting the targets, suggests a continuous developmental plan for low-priced cosmetics through securing potential customers and segmenting market, and analyzes and typologizes female undergraduates lifestyle. The aim is to grasp the actual condition of using the low-priced cosmetics and the satisfaction with purchase, and to utilize it as basic date of inducing right consumption culture of female undergraduates. For this study, 305 reliable questionnaires are analyzed from the total 320 questionnaires and spss win 15.0 program was used. The results were as follows. About 90.1 percent of female undergraduates had experience using low-priced cosmetics and standard of priority selection was the quality of low-priced cosmetics. The main reason not to use was low price image.

Objectives : The study was designed to test if alcohol use and alcohol-related problems among adolescent females are related to their parents' level of alcohol problems. Methods : In 2001, a stratified sample of 2077 adolescent females, grades 10-11, from twelve female-only high schools located in a large metropolitan city in the Republic of Korea completed a questionnaire about alcohol use, parental attention, and parental alcohol consumption, and other risk and protective factors. Data were analyzed with chi-square and regression analyses. Results : Nearly 63% of the student drinkers had experienced at least one to two alcohol-related problems in their lives. Two-thirds of all 2077 students indicated that at least one of their parents had an alcohol-related problem and that approximately 29% had experienced several problems. Results of random effects ordinal logistic regression analyses suggest a dose-response relationship between parental and youth alcohol-related problems. Youth who report having parents with some and many alcohol problems were 30% (Odds Ratios [OR] = 1.30; 95% Confidence Interval [CI] = 1.10 - 1.53) and 55% (OR = 1.55; 95%CI = 1.23 - 1.95) more likely to experience alcohol-related problems than youth whose parents do not have alcohol problems, respectively, after statistically adjusting for important covariates. Conclusions : This study presents evidence that alcohol-related problems among adolescent female students is highly prevalent. Also, the study findings reveal a high percentage of parents with alcohol problems, as reported by students. This study presents evidence of what might be a hidden problem among adults and youths in the Republic of Korea that merits serious attention.

The purpose of this research is to investigate young consumer motivation in regards to shopping mall. Young adults are an emerging age group that has economic autonomy and power of making independent decisions. In addition, this young segment providing an interesting challenges and opportunities for marketing professionals. Therefore, it is pertinent to analyse their shopping motivations, so that the marketers can understand and influence the consumption behaviour of this specific group. A survey using self-administered questionnaire was conducted to assess the mall-directed shopping habits and shopping orientations. A total of 164 usable surveys were obtained. In addition of exploratory factor analysis, confirmatory factor analysis and structural equation modeling was applied to prove the hypotheses. We have found that young Australian shoppers were motivated to visit malls primarily by the role enactment and exploration dimensions. They were the strongest motivators which explaining why young Australian consumers patronize malls. Young consumers of Australia enjoyed the mall environment, exploring new things, socializing with friends, comparing prices and the variety of products and services offered. The results of our study have several implications that should be of benefit to the retailing industry and mall management. Developers of malls must develop their mall more than simply a place for buying products. As such, mall management should make sure that their mall atmospherics offer a mall environment that is pleasing to multiple senses, to ensure it is conducive for shoppers to stay and spend more of their time and money. Mall management must execute strategies to maintain their attraction to younger consumers, perhaps by including stores that are futuristic and offer the most advanced styles or technologies, and appeal to somewhat older adults by offering the tenant, entertainment, and experience mix they will prefer. It is recommended that future research utilize random sampling methods to ensure the generalizability of results.

360VR content requires short latency, such as immediate response to viewers' viewport changes and high quality video delivery. It is necessary to consider efficient transmission that guarantees the QoE(Quality of Experience) of the 360VR contents with limited bandwidth. Several research has been introduced to reduce overall bandwidth consumption by predicting a user's viewport and allocating different bit rates to the area corresponding to the viewport. In this paper, we propose novel viewport prediction scheme that uses sound source location information of 360VR contents as auditory recognition information along with visual recognition information. Also, we propose efficient transmission algorithm by allocating a bit rate properly based on improved viewport prediction. The proposed scheme improves the accuracy of the viewport prediction and provides high quality videos to tiles corresponding to the user's viewpoint within the limited bandwidth.

With the growing demand for multimedia services and advances in display technology, new applications for 3$\sim$D scene communication have emerged. While multi-view video of these emerging applications may provide users with more realistic scene experience, drastic increase in the bandwidth is a major problem to solve. In this paper, we propose a fast prediction mode decision algorithm which can significantly reduce complexity and time consumption of the encoding process. This is based on the object segmentation, which can effectively identify the fast moving foreground object. As the foreground object with fast motion is more likely to be encoded in the view directional prediction mode, we can properly limit the motion compensated coding for a case in point. As a result, time savings of the proposed algorithm was up to average 45% without much loss in the quality of the image sequence.

While agricultural water has been declared free in Korea to ensure access to these limited resource since the year 2000, farmers have however developed lackadaisical behavior towards water saving leading to its scarcity. To overcome this problem, a variety of experience-oriented education model was developed for farmers to promote the adoption of water conservation, and preventive measure against the drought impacts. In this study, farmers' awareness and their attitudinal behavior of agricultural water savings were investigated. The monitoring of water supply structure and the repair facilities in Pohang and Yeongdeok areas were conducted. The field visits and behavioral surveys showed a high degree of over-use and illegal water withdrawals by the farmers due to poor water-saving and management practices. We found that most of the KRC employees strongly admitted the necessity of water-saving education. On the other hand, the farmers showed good interest in the implementation of water-saving awareness through education. Besides this, most farmers agreed to adopt water-saving practices in the fields. Farmers also acknowledged the recklessness of water use was due to the aging of waterways, poor water management, and illegal water consumption. The majority of the farmers responded against imposing the water-use tariffs. However, there was a low response to paying the water-use charge. Aging agricultural facilities and the lack of institutional penalties or incentives were the major obstacles in achieving efficient water-saving. Considering the current drought frequency, urgent water-saving education of farmers was deemed necessary to prepare the farming community against the water shortages. Based on the results of this study, we have to identify the irrigation practices of farmers and provide water-saving education to enforce more efficient use and management of agricultural water.

Objectives: This study (a) investigated the rate of smoking cessation sucess for current male smokers, and (b) identified the factors that are associated with the smoking cessation success. Methods: Data were collected from four follow-up surveys of 700 current male smokers. The follow-up period was from December 2004 to June 2005. Success of smoking cessation was defined as "maintaining a smoking cessation status for six months". The demographic and socioeconomic factors included age, the household income level and, occupation. The smoking behavioral factors were composed of the amount of smoking, the duration of smoking, the age of initiating smoking, the willingness to quit, the frequency of trying to quit smoking and the smoker's attitude toward the anti-smoking policies. Results: The proportion of quitters increased from 6.6% to 11.0% during the follow-up period. The majority of quitters answered that the increase of tobacco price acted as cue to achieve smoking cessation. The age-standardized experience and success rate of smoking cessation were 16.0% (95% C.I.=13.0% to, 19.0%) and 4.5% (95% C.I.=3.0% to, 6.0%), respectively. On the multivariate analysis, success for smoking cessation was associated with the willingness to quit smoking, low prior tobacco consumption, and agreement on the tobacco price increase. Conclusions: The results of this study suggest that the recent anti-smoking policies provided an opportunity to quit smoking. The results of this study can be used to establish evidence for further anti-smoking policies.

Due to poor nutrition and abnormal energy metabolism, cancer patients typically experience the loss of muscle mass. Although the diabetic conditions or dyslipidemia have been reported as a causal link of cancer but the consequence of such conditions in relation to gain or loss of skeletal muscle mass in cancer patients has not been well documented. The purpose of this study was to investigate the relationship of lean body mass and systemic parameters related to lipid metabolism in non-diabetic cancer patients using data from the Korean National Health and Nutrition Examination Survey (KNHANES) 2008-2011. As results the level of serum total cholesterol (total-C) was negatively associated with both total lean body mass and appendicular lean body mass in cancer patients after adjustment for sex, physical activity, energy intake and comorbidity. The associations between consumption of dietary factors (energy, carbohydrate, protein and fat) and lean body mass were disappeared after adjusting comorbidities of cancer patients. Multivariate-adjusted linear regression analysis by quartiles of serum total-C showed that higher quartile group of total-C had significantly lower percent of lean body mass than reference group in cancer patients. The data indicate that serum lipid status can be the potential estimate of loss of skeletal muscle mass in cancer patients and be referenced in nutrition care of cancer patients under the onset of cachexia or parenteral/enteral nutrition. This data need to be confirmed with large pool of subjects and should be specified by stage of cancer or the site of cancer in future studies.

Purpose: This study aimed to derive clues for the franchise industry to overcome difficulties such as various legal regulations and social responsibility demands and to continuously develop by analyzing the research trends related to franchises published in Korea. Research design, data and methodology: As a result of searching for 'franchise' in ScienceON, abstracts were collected from papers published in domestic academic journals from 1994 to June 2021. Keywords were extracted from the abstracts of 1,110 valid papers, and after preprocessing, keyword analysis, TF-IDF analysis, and topic modeling using LDA algorithm, along with trend analysis of the top 20 words in TF-IDF by year group was carried out using the R-package. Results: As a result of keyword analysis, it was found that businesses and brands were the subjects of research related to franchises, and interest in service and satisfaction was considerable, and food and coffee were prominently studied as industries. As a result of TF-IDF calculation, it was found that brand, satisfaction, franchisor, and coffee were ranked at the top. As a result of LDA-based topic modeling, a total of 12 topics including "growth strategy" were derived and visualized with LDAvis. On the other hand, the areas of Topic 1 (growth strategy) and Topic 9 (organizational culture), Topic 4 (consumption experience) and Topic 6 (contribution and loyalty), Topic 7 (brand image) and Topic 10 (commercial area) overlap significantly. Finally, the trend analysis results for the top 20 keywords with high TF-IDF showed that 10 keywords such as quality, brand, food, and trust would be more utilized overall. Conclusions: Through the results of this study, the direction of interest in the franchise industry was confirmed, and it was found that it was necessary to find a clue for continuous growth through research in more diverse fields. And it was also considered an important finding to suggest a technique that can supplement the problems of topic trend analysis. Therefore, the results of this study show that researchers will gain significant insights from the perspectives related to the selection of research topics, and practitioners from the perspectives related to future franchise changes.
