Purpose This study reviews technology acceptance research in the information system area and consumer behavior research in the marketing area, sets characteristics of convergence products, personality of consumers and communication channels as main concepts and demonstrates their effects on 'relative level of attraction' and 'intent to adoption. Design/methodology/approach The survey was conducted against potential consumers who have the intent to purchase electric communication media products that provides a variety of functions and service, such as a smart TV, a tablet PC and a smart watch. All items were adapted from previous literature and revised as appropriate the purpose of this study and measured on a 7-point Likert scale with answer choices ranging from "strongly disagree" (1) to (7) "strongly agree." Totally, 300 respondents participated in the survey. Out of the 276 respondents, incomplete or invalid 24 were discarded. With them, SPSS 18.0 and AMOS 20.0 for structural equation modeling were used for the analysis. Findings Main findings are as followed;- First, it is found that 'interrelationship of technology' and 'functional diversification' of convergence products has positive effects on relative level of attraction. Second, perceived behavior control has significant effects on the intent to adoption convergence products. Third, communication through mass media has positive effects on making potential consumers feel attraction about products while there is no relationship with the intent to a. On the other hands, it is demonstrated that there is no relationship influential relationship between communication through interpersonal channels and relative level of attraction while communication through interpersonal channels has significant effects on the intent to adoption.

Water, which is most abundant in Earth surface and very closely related to all forms of living organisms, has a simple molecular structure but exhibits very unique physical and chemical properties. Even though tremendous effort has been paid to understand this nature's core substance, there amazingly still lefts much room for scientist to explore its novel behaviors. Especially, as the scale goes down to nano-regime, water shows extraordinary properties that are not observable in bulk state. One of such interesting features is the formation of nanoscale bubbles showing unusual long-term stability. Nanobubbles can be spontaneously formed in water on hydrophobic surface or by decompression of gas-saturated liquid. In addition, the nanobubbles can be generated during electrochemical reaction at normal hydrogen electrode (NHE), which possibly distorts the standard reduction potential at NHE as the surface nanobubble screens the reaction with electrolyte solution. However, the real-time evolution of these nanobubbles has been hardly studied owing to the lack of proper imaging tools in liquid phase at nanoscale. Here we demonstrate, for the first time, that the behaviors of nanobubbles can be visualized by in situ transmission electron microscope (TEM), utilizing graphene as liquid cell membrane. The results indicate that there is a critical radius that determines the long-term stability of nanobubbles. In addition, we find two different pathways of nanobubble growth: i) Ostwald ripening of large and small nanobubbles and ii) coalescence of similar-sized nanobubbles. We also observe that the nucleation and growth of nanoparticles and the self-assembly of biomolecules are catalyzed at the nanobubble interface. Our finding is expected to provide a deeper insight to understand unusual chemical, biological and environmental phenomena where nanoscale gas-state is involved.

Large-scale copy number variants (CNVs) in the human provide the raw material for delineating population differences, as natural selection may have affected at least some of the CNVs thus far discovered. Although the examination of relatively large numbers of specific ethnic groups has recently started in regard to inter-ethnic group differences in CNVs, identifying and understanding particular instances of natural selection have not been performed. The traditional $F_{ST}$ measure, obtained from differences in allele frequencies between populations, has been used to identify CNVs loci subject to geographically varying selection. Here, we review advances and the application of multinomial-Dirichlet likelihood methods of inference for identifying genome regions that have been subject to natural selection with the $F_{ST}$ estimates. The contents of presentation are not new; however, this review clarifies how the application of the methods to CNV data, which remains largely unexplored, is possible. A hierarchical Bayesian method, which is implemented via Markov Chain Monte Carlo, estimates locus-specific $F_{ST}$ and can identify outlying CNVs loci with large values of FST. By applying this Bayesian method to the publicly available CNV data, we identified the CNV loci that show signals of natural selection, which may elucidate the genetic basis of human disease and diversity.

This study analyzed trends in geoscientific research funding provided by the Korea Science and Engineering Foundation (KOSEF) and examined strategies to promote geoscientific research. The strengths of geoscientific research in South Korea include the excellent academic quality of researchers, established research infrastructure, and inter-disciplinary research. Weaknesses include insufficient leadership in related societies and institutes, insufficient research productivity, and the exclusion of the field from nationally supported large-scale research projects. Opportunities for expanded research include environmental issues, the sustainable use of natural resources, the promotion of international research cooperation, and the initiation of national efforts to find solutions for regional problems. However, growth in the geosciences is threatened by prioritized investment in fields such as biotechnology, nanoscience, and information technology, a dismissive attitude toward the growth of basic sciences, and an increased demand for projects with visible economic and societal impacts. In terms of funding, group-based programs receive more support than individual-based programs. Between 1978 and 2006, KOSEF invested 1,744 billion won ($1.873 billion US) in a total of 46,748 basic research projects. Of this amount, 62.1 billion won ($66.7 million US) was allocated to 1,901 projects in the geosciences, which was roughly 2.6-10.6% of the money available in a given year. These funds were used to support research and development, the development and maintenance of necessary infrastructure, and the education and training of geoscientists.

Objectives: This study was conducted to investigate the effects of a self growth program through MBTI on interpersonal relationships, and the career identity of nursing college students. Methods: A randomized controlled pre-post test experimental design was used for this study. The 24 nursing students were randomly assigned into two groups: 12 for the experimental group, and 12 for the control group. The subjects were junior nursing students, who were randomly selected from an undergraduate nursing program at K university located in Daegu, Korea. The data was collected from March 18 to April 1, 2002. The MBTI self growth program used in this study was based on the one developed by Shim and Kim (1997). The 12 experimental group students received the group self growth program through MBTI for 15 hours, while the 12 control group students received no treatment, except a series of tests. The Korean version MBTI test used in this study was developed and verified for reliability and validity by Kim and Sim (1990). Change in inter-personal relationships was measured using the Relationship Change Scale developed by Schlein and Guerney (1971), and modified by Lee and Mun (1982). Career identity was measured using the My Vocational Situation developed by Holland. Daiger and Power (1980), and revised by Kim (1997). The data were analyzed with the SPSS Win 10.0 program, through which the 2 test, t-test, and Repeated measures ANOVA were examined. Results: 1) The first hypothesis, 'the experimental group that received the self growth program through MBTI will obtain a higher interpersonal relationship score than the control group', was supported (F=5.295. p=.031. Interaction: p=.000). 2) The second hypothesis, 'the experimental group that received the self growth program through MBTI will obtain a higher career identity score than the control group', was supported (F=28.575, p=.000, Interaction: p=.000). Conclusion: The results showed that the ready planned self growth program through MBTI had positive effects on improving the interpersonal relationships, and the career identity of nursing college students.

The western North Pacific subtropical high (WNPSH) in boreal summer has interannual and interdecadal variability, which affects East Asian summer monsoon variability. In particular, it is well known that the intensity of WNPSH is reversely related to that of summer monsoon in North East Asia in association with Pacific Japan (PJ)-like pattern. Many coupled climate models weakly simulate this large-scale teleconnection pattern and also exhibit the diverse variability of WNPSH. This study discusses the inter-model differences of WNPSH simulated by different climate models, which participate in the Coupled Model Intercomparison Project phase 5 (CMIP5). In comparing with reanalysis observation, the 29 CMIP5 models could be assorted into two difference groups in terms of interannual variability of WNPSH. This study also discusses the dynamical or thermodynamics factors for the differences of two groups of the CMIP5 climate models. As results, the regressed precipitation in well-simulating group onto the Nino3.4 index ($5^{\circ}N-5^{\circ}S$, $170^{\circ}W-120^{\circ}W$) is stronger than that in poorly-simulating group. We suggest that this difference of two groups of the CMIP5 climate models would have an effect on simulating the interannual variability of WNPSH.
