The purpose of this study was to examine the life satisfaction of adolescents in the ecological contexts of their individual, family, school, and social-cultural experiences. The participants were 1,099 middle and high school students in Chungnam-do. Instruments were the Satisfaction with Life Scale, Rosenberg Self-Esteem Scale, Parent-Adolescent Communication Inventory, the School Life Satisfaction Scale, and Social-Cultural Satisfaction Scale. Data analysis involved the use of descriptive statistics, t- and F-tests, Duncan's multiple range test, product-moment correlations, multiple regression, Cronbach's ${\alpha}$, and factor analysis. Results were as follows: Firstly, middle school students showed the highest levels of life satisfaction, and vocational high school students reported the lowest levels. Also, life satisfaction was inversely related to school grades. Secondly, for all the students, life satisfaction was positive correlated with self-esteem, open communication with parents, school life satisfaction, and social-cultural satisfaction. Lastly, open communication with parents and overall satisfaction with life at school explained more of the variance in adolescent life satisfaction than any other factors.

We investigated the ecological variables of adolescent sexual behavior. We grouped the behaviors into organism, microsystem, mesosystem, and exosystem. The variables belonging to the organism group were sexual attitude, sex, grade, sexual knowledge, sexual education, dating experience, problem behaviors, and self-control. The microsystem variables included the parent-adolescent communication about sexuality, parental monitoring, parent educational background, friend relationships, and school environment. Moreover, the mesosystem variables included family-peer and family-school relationships. The exosystem variables were comprised of neighborhood environment and pornography. The study group included 369 adolescents from the first and second grade of several high school in Daegu, Korea. We found that the factors affecting adolescent sexual behavior included grade, sex, dating experience, self-control, smoking, and pursuing sexual pleasure. As well, contact with deviant friends, father-adolescent communication about sexuality, school type, and attachment to teacher. In addition the family-peer relationship also affected adolescent's sexual behaviors as well as pornography and neighborhood environment. Lastly the variable belonging to the organism group was found to have the greatest effect on adolescent, sexual behavior compared to the other variables.

Using a psychometric paradigm, risk perception of 30 hazards was investigated for three social groups-college students, experts of technologies, and employees of environmental organizations. The aim of this study was to examine psychological dimensions of risk perception, namely, to replicate the psychological dimensions - dread and knowledge -, which Slovic et al(1978; 1984; 1987) found and to forker explore discrepancies between societal groups. The results confirmed the same psychological dimensions Slovic et al have found. However, there are a number of significant differences in perceived risk such as perceived social benefits and other risk characteristics between three groups that suggest differences in ecological attitudes. The results were compared with those of Slovic et af and the nature of differences in risk perception among three groups were discussed.

According to change a generation, in modern society the view which looks at the nature the people and the space is changing. As recognition which the environment is the most important factor in our society, there are researches that environment has to preserve and there are methods that the environment is related with the human, therefore, in the space ecology design views that similar to modern society are being shift. Museum of natural environment is public and popular space that it is designed and composed by a method of ecology space design. Hence, on this study, the museum of natural environment is defined public space by ways of characteristics of ecology design and a design characteristic which the museum of natural environment basically has to arrange are examined. Gallery of natural environment is most related with subsidiarity of mutuality, unity of the totality and stablity and will need other factors such as diversity & balance and suitability. Characteristic of museum of natural environment will be understood method for extension of a sustainable and mutual public space based on the this study, and it will become a process that we will have to advance for not only the present day but also the future.

The purpose of this study is to investigate the environmental perceptions of pre-service secondary school teachers about the global environment. The Subjects are 133 pre-service secondary school teachers. As an indicator of environmental perceptions, the modified New Environmental Paradigm (NEP) instrument was used. This modified NEP instrument consists of four dimensions: the negative results of growth and technology, relation of humankind and nature, quality of life, and limits of biosphere. The results of this study suggested that a majority of pre-service secondary teachers held ecological environmental perceptions. They also had a similar environmental perception to education major. However, there were significant differences in environmental perceptions and the variables of education experience on environment-related subjects. Based on the findings of this study, it is recommended that environment-related subjects. Based on the findings of this study, it is recommended that environmental education be a mandatory course in education programs.

Purpose: This is a descriptive survey research study that identifies the intrapersonal, interpersonal, and organizational and community factors affecting the instrumental activities of daily living (IADL) in community-dwelling seniors. Methods: The study used data from a 2017 national survey of senior citizens, and includes 10,299 subjects aged 65 years or more. Complex sampling was performed to increase accuracy of the population, and hierarchical logistic regression was performed to identify the factors affecting IADL in seniors. Results: Amongst the organizational and community factors, we determined that the number of health centers, welfare facilities for senior citizens, hospital beds, and community sport facilities affected IADL in seniors, even after adjusting for intrapersonal and interpersonal factors. Conclusion: Helping seniors to maintain IADL independence for a longer duration is essential for their physical and social independence. Therefore, when establishing and developing policies for health promotion programs, efforts should be undertaken to actively reflect the level of IADL functions, and to create an accessible health and medical welfare environment by considering characteristics of senior citizens for operating programs.

We conducted a phylogeographic analysis of Korean endemic Zacco koreanus populations inhabiting the East-flowing river (Gangneung Yeongokcheon; GY, Yangyang Namdaecheon; YN), the Han River (Seomgang; SG, Soksacheon; SS), and the Nakdong River(Gilancheon; GA) using the mitochondrial DNA cytochrome oxidase I (COI) gene (619 bp). Population genetic analysis was further performed to assess the population connectivity for the GY river where there is a large number of human-made artificial weirs with several fishways. The phylogeographic analysis revealed that while the populations of the East-flowing river and those of the Han River formed a monophyletic lineage, the Nakdong River individuals represented a distinct lineage with 3.7-4.2% (mean=4.0%) genetic distance from the other lineages. The population genetic analysis of the GY showed that a mid-stream population harbored relatively higher mitochondrial diversity relative to up- and down-stream populations, and there was no genetic differentiation between these three populations. The latter findings might suggest high genetic connectivity between the populations via genetic flow along the fishways. However, an analysis using faster-evolving genetic markers, such as microsatellites, is needed to confirm the findings of high population connectivity. Our study suggests the possibility of the presence of cryptic species in Z. koreanus in the Nakdong River basin. However, further study with more individual samples as well as additional markers or even more advanced genomic tools is required to test our hypothesis. Ecological or phenotypic analyses should be conducted to test whether the observed Nakdong River lineage represents a different or cryptic species, or simply hidden, but excessive, intraspecific diversity.
