Lacquer has a high value as a coating of typical arts and crafts in East Asia including Korea, Japan, and China and traditional representative of the gorgeous satin that is fit to the cultural conditions of each region. Lacquer is harmless to the human body and its robustness, preservatives, moth proofness, and strong heat resistance can maintain a long life. It seems that it will be able to make a significant contribution to create a variety of products if we continually study and raise the productivity and quality of the goodness of these lacquer. In this context, we reviewed the Pitae lacquer wares, which is one of the lacquer of traditional techniques that can be applied to the development of daily necessities and cultural product. Joining the goodness of harmless and environment-friendly lacquer and the characteristics of the leather that can produce a variety of physical beauty can develop household goods of tradition and modernity in harmony. It is worthwhile re-interpreting the tradition in the aspect that we can develop our culture from a modern, plastic, and artistic point of view.

The interest in convenience food has increased over the years. Many researchers have tried to discover what factors affect the consumption of convenience food. Despite the diversity of studies, few studies emphasize a household's income. The aim of this article is to identify the different consumption patterns between upper, middle, and lower income brackets. Generally, households with higher income consumed more convenience food or the relationship was not significant. However, many convenience foods are regarded as nutritionally unbalanced and have a lower quality. So, the hypothesis cannot be easily confirmed because there are tradeoffs not only between health, as nutrition balance and cost, but also health and convenience. Thus, there is a need to indicate the divergent attributes of buying convenience food in a distinct income group. In addition, the convenience food is subdivided into two distinct categories: convenience food as a substitution for a whole meal (unhealthy) and substitution as part of a diet (healthy). We found that higher income groups purchase healthier convenience food while lower income groups purchase unhealthier convenience food. Also there are distinct attributes that influence the consumption of healthy and unhealthy convenience food.

This study intended to identify the effects of consumer ethnocentrism and fashion leadership on purchasing attitude toward luxury brands. This study also identified differences in consumer ethnocentrism and fashion leadership according to demographic characteristics and the relationship between ethnocentrism and fashion leadership. The data used in this study were gathered through surveying university students living in Seoul using convenient sampling method, and 325 questionnaires were used in t test, F test, and regression analysis. The results showed significant differences in consumer ethnocentrism according to age, clothing expenditure, monthly pocket money and in fashion leadership according to age, major, clothing expenditure, monthly pocket money, and monthly household income. There was no significant relationship between consumer ethnocentrism and fashion leadership. Consumer ethnocentrism negatively influenced the purchasing attitude whereas fashion leadership influenced positively. The results of this study provide insights into young consumers' increasing demands toward luxury brands and suggest some promotional tools that might prove effective.

Two phase sampling design is useful to increase estimation efficiency using deep stratification, improved non-response adjustment and reduced coverage bias. The same sampling units are commonly used for the first and the second phases in complex two-phase sampling design. In this paper we consider a sampling scheme where the first phase sampling units are clusters and the second phase sampling units are list samples. Using selected clusters in first phase requires that we list up elements in the selected clusters from the first phase and then use the list as a secondary sampling frame for the second phase sampling design. Then we select second phase samples from the listed sampling frame. We suggest an estimator based on the complex two-phase sampling design with different sampling units of each phase. Also the estimated variances of the estimator obtained by using classic and replication variance methods are considered and compared using simulation studies. For real data analysis, 2010 Korea Farm Household Economy Survey (KFHES) and 2011 Korea Agriculture Survey (KAS) are used.

The quality of various noises generated in the refrigerator is one of the important factors in deciding quality of the product. The main focus of sound control design has been shifted from reduction of sound level to improvement of sound duality for customer's preference. Up to date the purpose of noise control is the minimization of noise level. However despite of gradual decrease of noise level, occasionally the perceptional quality of noise has not been improved. In this paper, the relation between subjective and objective evaluation of sound quality has established and sound quality index is developed using ANN for evaluation of refrigerator's noise of both the starting noise and the stable running noise of compressor. To verify the usefulness of the index, the results in this paper have been compared with those surveyed by Consumer Union in USA.

This paper explores variables that influence the prediction of OTT service experience and free(AVOD)/ paid(SVOD) service use. Research results showed that five variables such as gender, age, personal income, household composition, and e-commerce use experience had a significant impact on identifying OTT service experience and whether to use free or paid services. Also, it was found that the probability of using SVOD increases as they prefer news and drama genres and use OTT services for more time. In summary, those who are relatively young, have a high personal income, and are more adapted to digital environments such as e-commerce are more likely to use SVOD.

This study aimed to suggest the direction and guideline of specific program for single households in the Healthy Families Support Centers. This study focused on Seoul area. To collect the data the in-depth interviews for 9 staffs managing the program for single person in field are progressed. The major results were as follows. First, we found the demand and validity of a specific program for single person households. Because they are different each other in the context of age, sex, marriage experience, everyday life and need for program. So the specific programs can give higher satisfaction to the single person household. Second, to manage the specific program effectively in field we need the retraining of staffs, sharing materials between centers and other institutions, presentation and communication about the information on program management in field.

Purpose: This study was conducted to examine the prevalence of current smoking and the factors that influence current smoking among male high school students in Korea according to school type. Methods: Data were extracted from the Korea Youth Risk Behavior Web-Based Survey (2017) and multiple logistic regression was used based on complex sample analysis. The study sample comprised of 15,777 male high school students: 12,583 from general high schools (GHS) and 3,194 from specialized vocational high schools (SVHS). Results: The prevalence of current smoking was significantly higher in SVHS students (19.6%) compared to GHS students (12.6%). Low academic achievement, depressive symptoms, current drinking, and high household economic status were commonly associated with current smoking in male students from both school types. However, exposure to secondhand smoking at home, non-exposure to anti-smoking advertisement, exposure to tobacco advertisement, participation in smoking prevention or cessation education were related to current smoking in GHS students, while living in rural area was associated with current smoking in SVHS students. Conclusion: To reduce current smoking among male high school students, it is necessary to develop smoking prevention policies reflecting the factors associated with current smoking that are different by school type.

Eight years have passed since the Korean government's medical agency officially reported that the fatal lung disease found in some hospitals in 2011 was caused by chemical disinfectants used in household humidifiers, marking the introduction of the humidifier disinfectant disaster. Over the past eight years, a medical-scientific approach has been taken by the Korean government in its efforts to solve the problems in terms of relief of and compensation for the potential victims. One of the unintended consequence of this approach has been the fact that the number of "official victims" recognized by the government is quite small compared to the total number of applicants who claim to be suffering from the humidifier disinfectant disaster. This is mainly due to the fact that the medical-scientific approach relies on excessively strict, rigid, and narrow medical-scientific criteria provided by medical experts for judging the degree of applicants' bodily damage from the use of humidifier disinfectants. As a result, this medical-scientific approach is becoming increasingly criticized by patients' organizations mainly composed of rejected applicants. Based on the analysis of the limits of this medical-scientific approach and after clarifying the social implications of the disaster from a sociological perspective, this paper proposes certain social approaches focused on participatory governance as a means of dealing with the current issue. Finally, the paper emphasizes that the act of taking social responses to the humidifier disinfectant disaster should also be considered a process of enlarging and deepening democracy in Korea.

This study investigated the extent to which rice producers from the Ayeyarwaddy Region of Myanmar could improve their productivity if inputs were used efficiently in rice cultivation. To achieve this objective, simple random sampling was used to collect data from 300 rice growers in the study area. Data were analyzed with the translog stochastic frontier approach to understand the production efficiencies. The study further estimated the influencing factors that affect the efficiency levels of rice farmers. The empirical result reveals that the average technical, allocative, and economic efficiencies were at 76.11, 47.85, and 34.15%, respectively. This suggests that there is considerable room for improving rice production by better utilization of the available resources at the current level of technology. This study suggests that strenthening agricultural training programs and adoption of improved rice varieties may reduce overall inefficiencies among rice farmers in Myanmar. Factors like age, household size, education, farming experience, farm size, rice variety, training, and off-farm income have a significant impact on increasing/decreasing farmer's efficiency. Efficiency can be improved by establishing farmer field school programs to increase the scale of operations. The government should encourage young educated people to participate in paddy production and also intervene to reduce input prices and control the quality of seeds.
