This paper is to analyze the current status and interdependence of knowledge regarding innovation related research in Korea, based on the four academic journals such as Journal of Korea Technology Innovation Society, Journal of Technology Innovation, The Korean Venture Management Review, and Research Policy. The major contributions of this research are as follows: First, we tried to see the general picture of the innovation research community by extending the boundary of analysis, not limiting to a specific journal. Second, instead of subjective and qualitative analysis relying on an expert review, we quantitatively analyzed various basic statistics on innovation area and confirmed that there exist differences for using key words across the journals. Third, we derived a set of influential papers in terms of the authoritative and hub indexes employing link analysis techniques. Finally we provided some recommendations for facilitating knowledge creation activities of academic journals in this area.

With the wide deployment of biometric authentication systems, several issues pertaining security and privacy of the biometric template have gained great attention from the research community. To resolve these issues, a number of biometric template protection methods have been proposed. However, the design of a template protection method to satisfy four criteria, namely diversity, revocability and non-invertibility is still a challenging task, especially performance degradation when template protection method is employed. In this paper, we propose a novel method to generate a revocable minutiae-based fingerprint template. The proposed method consists of feature extraction from fingerprint minutiae pairs, quantization, histogram binning, binarization and eventually binary bit-string generation. The contributions of our method are two fold: alignment-free and good performance. Various experiments on FVC2004 DB1 demonstrated the effectiveness of the proposed methods.

In this perspective paper, we present seven elements of the appropriate educator mindset for teaching in the constructivist elementary mathematics classroom. The elements include supporting students as they construct their own understanding, eliminating deficit view of slow learners, setting new understanding and growth as the learning objective, providing opportunities to co-construct meaning with peers, using student contributions as the source of curricular material, encouraging all students to participate in learning, and providing instruction not bounded by time. In our struggles to provide authentic, inclusive elementary classrooms, we hope that our discussion of the educator mindset can increase discourse on constructivism from philosophy to practice in the community of mathematics education and policy makers.

Bioinformatics education can be defined as the teaching and learning of how to use software tools, along with mathematical and statistical analysis, to solve biological problems. Although many resources are available, most students still struggle to understand even the simplest sequence alignment algorithms. Applying visualizations to these topics benefits both lecturers and students. Unfortunately, educational software for visualizing step-by-step processes in the user experience of sequence alignment algorithms is rare. In this article, an educational visualization tool for biological sequence alignment is presented, and the source code is released in order to encourage the collaborative power of open-source software, with the expectation of further contributions from the community in the future. Two different modules are integrated to enable a student to investigate the characteristics of alignment algorithms.

In this study, we examined the contribution of nitrogen oxides and volatile organic compounds emitted from China and Japan to ozone concentrations over Gwangyang-bay, South Korea. We used a chemical transport model, Community Multi-scale Air Quality model, and its instrumented sensitivity tool, High-order Decoupled Direct Method. Intercontinental Chemical Transport Experiment-Phase B 2006 for East Asia and Clean Air Policy Support System 2007 emissions inventories for South Korea were used for the ozone simulation. During the study period, May 2007, the modeled maximum daily 8-hr average ozone concentration among seven air quality monitors in Gwangyang-bay was 68.8 ppb. The contribution of $NO_x$ emissions from China was 19.5 ppb (28%). The highest modeled ozone concentrations and Chinese contributions appeared when air parcels were originated from Shanghai area. The observed 8-hr average ozone concentrations in Gwangyang Bay exceeded the national ambient air quality standard (60 ppb) 203 times by daytime and 56 times by nighttime during the period. It was noticed that many exeedances happened when contribution of Chinese emissions to ozone concentrations over the area increased. Sensitivity analysis shows that a reduction in Chinese $NO_x$ and VOC emissions by 15% could lessen the total exceedance hours by 24%. This result indicates that high ozone concentrations over Gwangyang-bay are strongly enhanced by Chinese emissions.

The university is a top-level educational institution that requires not only the education of undergraduate and graduate students but also the education of ordinary citizens in the community. However, in civil society, university education is mainly focused on lifelong education, and additional measures are needed for universities to implement more education about civil society. Since 2014, the Korea Research Foundation has implemented humanities city support projects, and universities have implemented programs such as humanities lectures, humanities experiences, and humanities week by utilizing local humanities assets. Although these projects are meaningful in that they are carried out through the medium of the area where the university is located, and the scope of participation is wider than that of previous academic projects related to humanities, because they are still carried out by one-off projects, a regional literature center should be established that can continue to conduct the projects even after completion. Furthermore, an efficient network should be established with the institutions in the area in which the university is located.

Recently consumers to access various Word-Of-Mouth information on online. And eWOM (eWOM : electronic Word-Of-Mouth) information had an important effect on consumer attitude(purchase intention). The purpose of this study is to investigate what the general characteristics of eWOM and the effects of how these factors will affect credibility, eWOM acceptance and purchase intention. In this study, the model contains information characteristics variables(consensus, newness), community characteristics(tie strength, interaction) on eWOM characteristics. This study makes contributions as follows. First, information consensus had not effect on credibility. Second, information newness and community characteristics(tie strength, interaction) had a significant on credibility. Third, credibility is the important factor on eWOM acceptance. Lastly, eWOM acceptance had a considerable influence on purchase intentions.

Many studies of the phytoplankton community structure have been conducted using the CHEMTAX program on the basis of the photosynthetic pigment concentrations measured by a HPLC (High-Performance Liquid Chromatography) technique. The CHEMTAX program determines the contribution of each phytoplankton class to total phytoplankton biomass (chlorophyll a) based on the ratios of marker pigment to chlorophyll a of phytoplankton group. In this study, the marker pigment/chlorophyll a ratios were investigated in phytoplankton species isolated from marine waters around the Korean peninsula. These results were used as the input pigment ratios of the CHEMTAX program to investigate phytoplankton community structure in Korean coastal waters (Yeoja and Gamak Bay). There were significant differences in the ratios of marker pigment to chlorophyll a among the different species within the same algal class. There was a significant difference between the values of our ratios and the previously used ratios in other regions of the world. When phytoplankton community composition was calculated using our initial ratios in Yeoja and Gamak Bay, our results were significantly different from the results calculated on the basis of initial ratios of marker pigment in phytoplankton suggested in other marine waters. The estimates of the contributions of the major algal groups (bacillariophyceae and dinophytes) to total chlorophyll a varied within 5% depending on the initial ratios chosen. The variations of estimates for the pico- and nanoplankton (cyanophytes and prasinophytes), which have relatively low contributions to total chlorophyll a, were higher than those for major algal group. Although the HPLC-pigment measurements combined with CHEMTAX analysis are useful for identifying and qualifying phytoplankton community structure, further researches for the pigment ratios of the dominant phytoplankton species presenting in a given area are also needed.

Incheon International Airport (IIAC) has been named "best airport worldwide" according to the AETRA Passenger survey Program that was jointly administered by Airports Council International (ACI) and the International Air Transport Association (IATA) in 2005. This paper identifies eight dimensions underlying the overall service qualify in passenger terminals. These eight elements were found from literature reviews through relevant documents. The research explains the linkage between the overall satisfaction with IIAC and five services that influence that satisfaction. The five services are the following: service quality of passenger terminals, commercial facility services, easy access by transportation, service quality of the airlines, and contributions to the community by IIAC. The data envelopment analysis (DEA) designed by Cook and Kress (CK Model) was used to maximize the efficiency of commercial facility services, easy access by transportation, service qualify of the airlines, and contributions to the community by IIAC because the model best provided practical plans for a more competitive airport. This paper has three significant results. First, it includes research of passenger terminal-oriented service quality. Second, the author researches service qualify focusing on a three-cornered relation among passengers, airline employees, and IIAC. Third, the paper contains research of service quality focusing on IIAC's employees.

This study explores the effects of rural migrant characteristics and conjugal communication on life satisfaction of baby boomer rural migrants. A total of 205 Korean baby boomers, who are living in rural areas in the year of 2013 that had migrated from cities back in 2003 with their families, were analyzed. Their age ranged from 49 to 57 years. The statistical methods used for data analysis were descriptive statistics, t-test, and hierarchical regression analysis, with SPSS Win 20.0 program. The results of this study are summarized as follows: the reasons these baby boomers chose a rural lifestyle were 'for life after retirement,' 'because rural life is good,' 'for health reasons,' and 'for chosen profession.' The level of conjugal communication (M=3.69) and life satisfaction (M=3.23) were higher than average (M=3.0). The variables influencing life satisfaction of baby boomer rural migrants were 'increased property size,' 'better conjugal communication,' 'better health condition,' 'lower levels of money,' and 'length of time spent farming.' Furthermore, in terms of life satisfaction, the relative contributions of these variables are as follows: general characteristics 20%, rural migrant characteristics 10%, and the level of conjugal communication 6%. These results show that conjugal communication is a very important variable, as well as a rural migrant characteristic when it comes to life satisfaction of these baby boomers. Therefore, to improve life satisfaction of baby boomer rural migrants, support programs need to focus on both farming and conjugal relationships.
