School forests, an important part of the urban forest, has diverse functions and plays an important role in artificial environment. It has three main functions: educational for children, ecological for nature, and cultural for residents. In spite of its diverse functions and roles, the actual conditions and achievements of school forests have not been correctly evaluated, resulting in institutional inertia. To improve these problems, this study was synthetically conducted by the post occupancy evaluation of users(residents, teachers and students) at school forests. This study can be summarized as follows: 1. The cognition and satisfaction level of school forests supported by private organizations was higher than those by local governments. Therefore, the establishment of a post management system of private organizations is more effective than the simple financial support of local governments. 2. The frequency of use of school forests by residents was higher than that of teachers. Their purposes were mainly to rest or walk However, teachers used school forests for nature observation and education. 3. In a survey of teachers about a reform measure and problems of school forests, the necessity of a post management system and financial security were significant requests. In addition, steady publicity and education, participant program, and incentives for teachers should be considered. This study is meaningful to systematically develop and activate the school forest movement. The integrated approach to the school forest movement reflects opinions of related users and is expected to become a useful foundation in studying about the improvement of city environments.

This study explores the daily life of Korean designers in New York. We use in-depth interviews within the daily lives of participants to first reveal the time structure and meaning of everyday life. In this everyday time frame, this study reveals the content and meaning of life in New York, which is especially useful for fashion majors. Participants were 11 single Korean women around 30 years old working as designers in New York. Data was collected from Manhattan, New York, from November 2013 to February 2014 through the use of in-depth interviews and participant observation. Data collected daily life information on time usage, money, and energy that is first summarized into 229 meaning units. In the following, 55 central meanings were derived from stories common to behaviors for study participants and 19 subcategories were compressed into academic language. Finally, the generalized categories are divided into six categories of study life, work life, future life, family life, leisure life and fashion life. As a result of the first study, the daily time structure consisted of customary public time and personal repeat time. Second, the customary public time categories included the studying for 'Beginning to jump again to the best', 'Now working as a designer in New York', and future life expecting 'Future growing as a career woman'.

Session initiation protocol (SIP) is an application-layer prolocol to initiate and control multimedia client session. When client ask to use a SIP service, they need to be authenticated in order to get service from the server. Authentication in a SIP application is the process in which a client agent present credentials to another SIP element to establish a session or be granted access to the network service. In 2005, Yang et al. proposed a key exchange and authentication scheme for use in SIP applications, which is based on the Diffie-Hellman protocol. But, Yang et al.'s scheme is not suitable for the hardware-limited client and severs, since it requires the protocol participant to perform significant amount of computations (i.e., four modular exponentiations). Based on this observation. Huang and Wei have recently proposed a new efficient key exchange and authentication scheme thor improves on Yang et al.'s scheme. As for security, Huang and Wei claimed, among others, that their scheme is resistant to offline dictionary attacks. However, the claim turned out to be untrue. In this paper, we show thor Huang and Wei's key exchange and authentication scheme is vulnerable to on offline dictionary attack and forward secrecy.

Purpose: This study was done to develop a theory on the early childhood caring experience of North Korean refugee mothers and how such caring affects how they deal with the socio-psychological problems they face as North Korean refugees. Methods: Data were gathered by indepth interviews, participant observation, and medical records, and were analyzed using the Grounded Theory methods of Strauss and Corbin (1998). Results: From open coding 62 concepts, 23 subcategories and 11 categories were derived, and the North Korean refugee mothers' caring experience was revealed to be 'hopeful upbringing'. A central theme common to the participants was 'coexistence of expectations and worries'. Conclusion: The results of this study provide theoretical grounds to understand North Korean refugee mothers' child care experiences and offer personalized nursing and a deeper understanding of their needs by looking at their experience. Findings may also be useful to help nurses who care for North Korean refugee mother-child dyads in the community and in clinical settings to gain insight on this special needs group, and facilitate the development of interventions based on better understanding of the mothers' experiences.

Background: Insufficient training in infection control and occupational health among healthcare workers (HCWs) in countries with high human immunodeficiency virus (HIV) and tuberculosis (TB) burdens requires attention. We examined the effectiveness of a 1-year Certificate Program in Occupational Health and Infection Control conducted in Free State Province, South Africa in an international partnership to empower HCWs to become change agents to promote workplace-based HIV and TB prevention. Methods: Questionnaires assessing reactions to the program and Knowledge, Attitudes, Skills, and Practices were collected pre-, mid-, and postprogram. Individual interviews, group project evaluations, and participant observation were also conducted. Quantitative data were analyzed using Wilcoxon signed-rank test. Qualitative data were thematically coded and analyzed using the Kirkpatrick framework. Results: Participants recruited (n = 32) were mostly female (81%) and nurses (56%). Pre-to-post-program mean scores improved in knowledge (+12%, p = 0.002) and skills/practices (+14%, p = 0.002). Preprogram attitude scores were high but did not change. Participants felt empowered and demonstrated attitudinal improvements regarding HIV, TB, infection control, and occupational health. Successful projects were indeed implemented. However, participants encountered considerable difficulties in trying to sustain improvement, due largely to lack of pre-existing knowledge and experience, combined with inadequate staffing and insufficient management support. Conclusion: Training is essential to strengthen HCWs' occupational health and infection control knowledge, attitudes, skills, and practices, and workplace-based training programs such as this can yield impressive results. However, the considerable mentorship resources required for such programs and the substantial infrastructural supports needed for implementation and sustainability of improvements in settings without pre-existing experience in such endeavors should not be underestimated.

In this research, we observed the co-works among novice and expert science teachers who were involved in a science teacher association and explored their interactions. The science teacher association is K-12 science teachers' gathering near Seoul. This study is a case study with the participant observation and the private interview of 8 novice teachers and 3 expert teachers. Based on the collected data, interaction between novice and expert teachers was categorized as seven types; question and answer, demonstration, presentation, co-working, providing materials, listening, and showing interest. Several factors supporting such an active interaction were derived from this study; 1) Teachers perceived well about the importance and the merits of co-working with other science teachers. 2) The open and cooperative environment of the science teacher association supported teachers' interaction. 3) There were tasks that teachers needed to co-work such as the science fair and the science camp. 4) There were opportunities of interactions for publishing books and developing modules. 5) Lots of expert teachers were willing to help and co-work with novice teachers. We found that novice teachers could continue to grow in terms of the professional development under interactive, continuing and cooperative environment with expert teachers.

As the proportion of the elderly population in rural Korea has increased rapidly, the quality of life of the rural elderly has become a major public and policy concern. In this regards, most of the researches on rural elderly have focused mainly on the 'risk factors or problems' of rural areas, ignoring the 'positive or protective aspects' of rural community on the quality of life of elderly. This study attempts to explore the possible positive influence of rural community on the quality of life of elderly and to examine the linkage among ecological characteristics of the communities, social interaction and quality of life of rural elderly. To achieve this goal, a community case study was conducted in four Korean rural villages. The data were collected using participant observation method and in-depth interviews (person-to-person, group interviews). All the interviews were tape-recorded and transcribed verbatim for the analysis. The data was analyzed using the reflective qualitative analytic technique. The major findings of this study are as follows : All of the four villages have strong community ties and provide contexts which make it possible for older people to share their everyday life with neighbors and to actively participate as a community member. Although the four villages were geographically not far from each other, the pattern of social interaction and the nature of everyday-life of the elderly were nevertheless different depending on the ecological environment of each community, the relationship history among the community members, and the shared experience of historical events in recent Korean history. Elderly men have smaller networks and have less frequent contact with community members than elderly women. The political and practical implications of this study are discussed.
