Purpose - This is longitudinal research which aims to investigate the meaning of greenness to consumers' behavior. Consumers adopt green marketing as a new factor in product buying and consumption and more and more consumers prefer green product and services. Consumers' green buying behavior can be different from other purchasing experiences. There would be changes in the meaning of green as time passed and it can be different from countries to other countries. This study examines focus group studies with several groups. There is a ten-year gap between 2010 focus group and 2019 focus group interviews. With this ten-year gap, we can find the change of greenness to consumers. Research design, data, and methodology - The data were collected from Turkish, Korean, Kazakhstan people. This is a cross-sectional study and focus group interview was designed. We can gain information relevant to the research problem with using focus group study and get some insights into basic needs and attitudes of green marketing. The subjects for green purchase interviewee were confined to under 40 years old's shoppers regardless of gender. The first study was investigated with several groups in 2010 and the second interview were conducted in 2019. Results - Results show that the meaning of greenness for consumer has changed over time in accordance with the growing accordance of environmental sustainability. Basically, green marketing still means valuable, natural, recycle-able, good for health, clean, smart behavior, essential benefit. The concept of greenness significantly evolved since it was investigated in 2010. It moves away from focusing on specific environmental issues to considering global sustainability issues. Especially we found that greenness can be related with globalization, higher education, social status at the 2019 interview. Conclusions - This paper attempted to confirm the green marketing is essential and expands its meaning to various aspect. Usually, we can think green marketing is everywhere, therefore, people don't care about green issues in real. But consumers are adopting green marketing more and more, it can be a means to attract potential consumers. Therefore, companies should provide enough greenness information for people and they might apply greenness communication to attract potential customers.

The finite element modeling is used to study the buckling and postbuckling behavior of composite laminates with an embedded delamination. Degenerated shell element and rigid beam element are utilized for the finite element modeling. In the nonlinear finite element formulation, the updated Lagrangian description method based on the second Piola-Kirchhoff stress tensor and the Green strain tensor is used. The buckling and postbuckling behavior of composite laminates with a delamination are investigated for various delamination sizes, stacking sequences, and boundary conditions. It is shown that the buckling load and postbuckling behavior of composite laminates depend on the buckling model which is determined by the delamination size, stacking sequence and boundary condition. Also, results show that introduction of couplings can reduce greatly the buckling load.

In swarm robot systems, it is vital to maintain network connectivity to ensure cooperative behavior between robots. This paper deals with the behavior control algorithm of the swarm robots for maintaining network connectivity. To do this, we divide swarm robots into search-robots, base-robots, and relay-robots. Using these robots, we propose behavior control algorithm to maintain network connectivity. The behavior control algorithms to maintain network connectivity are proposed for the local path planning using virtual force and global path planning using the Delaunay triangulation, respectively. Finally, we demonstrate the effectiveness and applicability of the proposed method through some simulations.

This study develops a new type of latent class analysis (LCA) in order to explain the associations between one latent variable and several other categorical latent variables. Our model postulates that the prevalence of the latent variable of interest is affected by another latent variable composed of other several latent variables. For the parameter estimation, we propose deterministic annealing EM (DAEM) to deal with local maxima problem in the proposed model. We perform simulation study to demonstrate how DAEM can find the set of parameter estimates at the global maximum of the likelihood over the repeated samples. We apply the proposed LCA model in an investigation of the effect of and joint patterns for drug-using behavior to violent behavior among US high school male students using data from the Youth Risk Behavior Surveillance System 2015. Considering the age of male adolescents as a covariate influencing violent behavior, we identified three classes of violent behavior and three classes of drug-using behavior. We also discovered that the prevalence of violent behavior is affected by the type of drug used for drug-using behavior.

To pursue youth and agelessness can be regarded as a global trend today. The younger a woman recognizes herself to be, the more sensation seeking tendency and the more active fashion exploratory behavior of younger generation she would show. This study attempted to empirically examine the relationship between sensation seeking behavior and fashion exploratory behavior according to the difference age in women in their 30's to 50s'. After the survey, a total of 480 questionnaires was used for data analysis. The results of this study are as follows, 1. It was found that there was a very high correlation among cognitive ages, and the lower cognitive age a woman had, the higher difference age she showed. 2. Sensation seeking tendency of adult women was shown in two factors of change seeking and artistic sensation seeking, and these factors accounted for 73.99% of the total variances. Fashion exploratory behavior had 4 factors such as fashion leadership, behavior of hedonic shopping, behavior of clothing communication and behavior of clothing purchase with taking a risk, and these four factors accounted for 75.87% of the total variances. 3. The higher difference age and the higher tendency of sensation seeking an adult woman had, the higher fashion exploratory behavior was shown, and the higher the difference age, the higher tendency of change seeking and artistic sensation seeking.

Much of the behavior of doctors reflects the influences from the social, cultural, historical, and economic environment of the time. Therefore, it is very important for future doctors to understand the practice environment in an ever changing world. Traditionally, doctors' competence has been based on the doctor-patient relationship. However, the social practice of medicine in the contemporary era asks future doctors to have social competencies, which often are defined as non-clinical competencies. As a global project, the World Federation for Medical Education has urged every country to define the future role of doctors to encompass global roles based on the duty toward and value of clinical as well as non-clinical competencies. In the past four years, Korean medical professional societies have coordinated to set forth the global role of Korean doctors. Five domains of clinical competence, professionalism, social accountability, communication and collaboration, and education and research have been chosen. The current version of the "global role of Korean doctors" can be used not only for the common objectives of medical education, but also for translating into the competencies of doctors that can be achieved through life-long learning. If we all want to improve medical education in order to produce more qualified and competent doctors as the public desires, then it may be the most urgent task to produce doctors who are equipped with social competencies to persuade, negotiate, and engage in constructive dialogues with society for better health care for a better society.

Objectives : The purposes of this study were to examine the health-related quality of life(HRQoL) and to identify its related factors for a group of rural adults. Methods : The study subjects were 1,901 adults who were aged 40-70 years and who were living in Naju City, Jeollanamdo. The sociodemographic characteristics, health-related behavior, health status and global self-rated health were collected for statistical analysis. The health-related quality of life was measured by the Euroqol EQ-5D instrument. The differences on the EQ-5D index between the groups were assessed with t-test, ANOVA and hierarchical multiple regression analysis. Results : Overall, the mean value of the EQ-5D index was $0.884{\pm}0.140$ and this score was significantly different according to the socioeconomic characteristics, the health-related behavior, the health status and the global self-rated health. According to the results from the hierarchical multiple regression analysis, the HRQoL was significantly reduced for females, older subjects, and other subjects with no spouse and the subjects with osteoporosis, obesity, mental distress or poorer global self-rated health. Conclusions : The HRQoL for rural adults was related to the socioeconomic characteristics, the health status and the global self-rated health, A better understanding of the factors related to the HRQoL would help to improve the rural adults' quality of life.

We consider a two-fare, two-period airline seat capacity allocation problem where consumers may choose different options in purchasing an airline ticket. A consumer may decide to wait for reopening of the same fare class ticket which is originally intended to buy, or may buy a different fare class ticket within the same period, if the originally requested fare is unavailable. We investigate the impact of the consumer buying behavior on the optimal solutions and the expected revenue.

This paper describes the behavior of prestressed concrete storage tanks under cryogenic temperatures by thermal stress analysis. In concrete tanks to store up LNG, a thermal shock can occur over a global area resulting from the sudden filling of the outer tank with cryogenic storage contents. Analysis results show that internal surface of concrete tank is cooled down rapidly. Tank is subjected mostly to thermal constraint moment due to temperature gradient across its section. Constraint moment may cause tensile stresses beyond tensile strength in the wall. Problems related with concrete cracking due to temperature gradient have been considered.
