Traffic congestion cost is increasing annually. Specifically congestion caused by the CDB traffic contains more than a half of the total congestion cost. Recent advancement in the field of Big Data, AI paved the way to industry revolution 4.0. And, these new technologies creates tremendous changes in the traffic information dissemination. Eventually, accurate and timely traffic information will give a positive impact on decreasing traffic congestion cost. This study, therefore, focused on developing both recurrent and non-recurrent congestion prediction models on urban roads by adopting Recurrent Neural Network(RNN), a tribe in machine learning. Two hidden layers with scaled conjugate gradient backpropagation algorithm were selected, and tested. Result of the analysis driven the authors to 25 meaningful links out of 33 total links that have appropriate mean square errors. Authors concluded that RNN model is a feasible model to predict congestion.

Objectives: The purpose of this study was to examine the prevalence of allergic rhinitis between urban areas in the adjacent areas to a steel industrial complex and rural areas and the impact of pollutants in the industrialized city on allergic rhinitis. Methods: From July 28 to August 9 of 2008, 1,043 residents of urban and rural areas in a local community had enrolled in health screening and questionnaire survey. One thousand thirty-three patients also underwent a skin prick test. Prevalence rates of allergic rhinitis were calculated according to residential areas, and the used statistical analysis were Fisher's exact test and chi-square test. Results: In a survey, the fraction of adults, who complained of sneezing, nasal obstruction and rhinorrhea, during a recent 1 year period, showed the significant difference between urban (30.5%) and rural areas (22.4%). The fractions of positive skin prick tests were not different between two areas in each age group. The prevalence of allergic rhinitis was 8.4% in urban areas and 6.9% in rural areas. Considering the age groups, the adults group only showed the significantly higher prevalence of allergic rhinitis in urban areas (8.2% vs. 3.7%). Conclusions: Unlike the children and adolescents groups, the prevalence of allergic rhinitis in adults group was higher in the industrialized urban areas.

This study investigates whether and how a firm's cost of equity is influenced by the extent of a firms's name change. Even though corporate name change doesn't give any benefit to investors, it can be a signaling about firm's future valuation. And also, if that signaling has high credibility, it can be decrease information cost and the firm's cost of equity. on the contrary to this, if corporate name change is kind of break with the past and corporate image laundering, it is bad signaling to investors. So it can be increase information risk and the firm's cost of equity. Using yearly cross-sectional regressions of the cost of equity on our proxies for corporate name change, size, beta, market-to-book ratio and other innate risk factor over the 2005-2010, we find that the cost of capital is positively associated with corporate name change after controlling for all other factors. This result implies that corporate name change increase information risk of the business, and thus increase information asymmetries between managers and outside investors with respect to a firm's true future value. This increases information risk, and creates an adverse selection problem, on the part of outside investors. Rational investors therefore demand a premium for bearing this corporate name change-related information risk, which in turn leads us to observe a positive relation between the intensity of corporate name change and the cost of equity.

This study examined the longitudinal relationship between depressive symptoms and alcohol use based on the tension reduction hypothesis and the intoxication hypothesis considering for path of depressive symptoms on alcohol use and vice versa simultaneously. And this study examined the effect of psychosocial behavior factors (i.e. smoking level, self-esteem, satisfaction with family relationships, and satisfaction with social relationships) on depressive symptoms and alcohol use. Using the data on the Korea Welfare Panel Study for the 1st, 2nd, and 3rd years, this study were estimated using the Latent Growth Curve Model which is helpful for examining differences between the two. The results are as follows: the initial level of alcohol use had a positive impact on the rate of change in depressive symptoms, thereby supporting the intoxication hypothesis. Second, self-esteem and satisfaction with family relationships act as variables with the biggest effect on the initial level and the rate of change in depressive symptoms, whereas other psychosocial behavior factors such as smoking level and satisfaction with social relationship exert the largest influence over the initial level and the rate of change in alcohol use. This study has implications in that it clarified the confused relationship mechanism between alcohol use and depressive symptoms the two.

This study examined the effect of the Collaborative Problem-Solving for Character Competence (CoProC) instruction model within the context of secondary science education. The participants of this study were comprised of 143 Korean students, each of whom was in the 10th grade spread across four class cohorts. These cohorts were further divided into an experimental group (comprised of 73 students from two different classes), which received the CoProC program; and a control group (70 students from two other classes), which did not. In order to assess the effect of CoProC instruction model upon participants' character competence, we designed and administered a Character Competence Test for participants. The CoProC instruction model consists of 3 fundamental steps: Preparation, Problem-solving, and Evaluation. Key character competence targeted in the CoProC program include caring, collaboration, communication, responsibility, respect, honesty, self-regulation, and the development of positive self-image. Thus, these same qualities were targeted and analyzed in the Character Competence Test, which was administered before and after the CoProC activities. The results show a significant increase in the experimental group's competency for caring, collaboration, responsibility, respect, and self-regulation when compared to the control group. Based on these results, we have found that CoProC instruction model to be an effective teaching intervention toward cultivating character competence in a secondary science education setting.

Due to the mobil-centered lifestyle following the wider use of Smartphones, Mobile services, including mobile banking and mobile shopping business have increased rapidly. Also with the emergence of "Fintech", which finance combined with technology, IT based financial market is going to be highly promising. In this trend, interests mobile credit cards are increasing. But diffusion of the mobile credit card services is still in the low level. In this situation, to identify factors that influencing satisfaction and continuous usage intention on mobile credit card, this study applied innovation diffusion theory (IDT) and post acceptance model (PAM). To conducting this research, survey data were collected, and we used SmartPLS to analyze survey data. As a result of the study, perceived easy of use, image, compatibility and facilitation positively affect user's satisfaction in mobile credit cards and that such satisfaction have a positive impact on continuous intention to use. The facilitation influences user satisfaction more strongly for those who use mobile credit cards more than plastic credit cards. Also, perceived of use and image influence user satisfaction more strongly for those who use plastic credit cards more than mobile credit cards. It is expected that this study can be a guideline for credit card service providers and policy makers to invigorate mobile credit card business. Also it worths as a early-stage research on Fintech-related studies.
