This study aims at identifying what effect ARCS model based instruction and cognitive style have on learning motivation and achievement in computer education. In order to accomplish this goal. 70 high school students were randomly allocated into the experiment group and the control group. And each group was divided into field-independent group and field-dependent group. The results were as follows. First, post test of learning motivation among four groups showed that mean differences were statistical significant. Especially 'ARCS model based instruction-field independent group got higher score than 'traditional instruction field dependent' group. Second, post test of learning achievement showed no significant mean difference among four group. The result of the pre and post test difference analysis showed that the change scores of means were significantly different.

In this paper, we consider Bayesian approaches to zero inflated Poisson model, one of the popular models to analyze zero inflated count data. To generate posterior samples, we deal with a Markov Chain Monte Carlo method using a Gibbs sampler and an exact sampling method using an Inverse Bayes Formula(IBF). Posterior sampling algorithms using two methods are compared, and a convergence checking for a Gibbs sampler is discussed, in particular using posterior samples from IBF sampling. Based on these sampling methods, a real data analysis is performed for Trajan data (Marin et al., 1993) and our results are compared with existing Trajan data analysis. We also discuss model selection issues for Trajan data between the Poisson model and zero inflated Poisson model using various criteria. In addition, we complement the previous work by Rodrigues (2003) via further data analysis using a hierarchical Bayesian model.

In Korea, the construction industry has been growing quantitatively because of its aggressive advances into overseas construction market and the Korean government's housing policy. Moreover, visions and goals such as 'construction industry promotion build up plan' have recently been promoted by the government while new strategic growth focused on competitiveness is gaining interests among the industry. However, there are a few problems in the construction performance. First, the specific performance measurement indicator or skills for the construction industry are hardly found in Korea. Currently, the finance or overall management system in the construction business are used as indicators to measure performances in not only the construction industry but all industries including the manufacturing industry. The government, the industry and universities recognized the need for the performance measurement indicator and skill and have developed and actively studied on them.

The study aims at analyzing and comparing the effect of video teleconferencing English class with native speakers on class satisfaction and self-efficacy of elementary school students according to grades. Revised Kim's self efficacy and researcher's class satisfaction measuring tools were used for this. Grade 3 got the highest score and grade 6 had the lowest one in class satisfaction. In post-testing on self efficacy, average score was lower than in pre-testing except grade 3. Grade 3 got the highest score and grade 6 had the lowest one in self efficacy. I conclude that as students' grade goes up, their interests decrease in teleconferencing class and native speaker teachers.

The present study used a hierarchical Bayesian approach was used to develop a mixed effect model to describe the transitional behavior of subjects in time nonhomogeneous Markov chains. The posterior distributions of model parameters were not in analytically tractable forms; subsequently, a Gibbs sampling method was used to draw samples from full conditional posterior distributions. The proposed model was implemented with real data.

The purpose of this study was to examine the effects of collaborative learning and explore the learners' experiences in three dimensions: cognition, emotion and motivation. Another purpose of this study was to make an in-depth examination of learners' experiences during collaborative learning. Data were collected from 44 students at N university who participated in collaborative learning for 7 weeks. The results were as follows: First, collaborative learning had significant effects on the higher group of collaborative tendencies on academic achievements. Second, collaborative learning had no significant effects on their epistemological beliefs, the higher group of collaborative tendencies and the lower beliefs involving simple knowledge and tentative knowing. Finally, learners amassed cognitive, emotional, and motivational experience during collaborative learning. We suggest that the for the effective implementation of collaborative learning.

In 2000, post-construction evaluation was introduced for the purposes to evaluate demand, cost, and construction period of public construction projects and to reduce errors of public order agencies. However, pricing guide of post-construction evaluation has not been established, which becomes a cause of quality degradation of post-construction service and conflict occurrence. This study suggests the pricing guide in the form of percentage of construction cost method and cost plus fee method based on data of post-construction evaluation. This study investigates the construction costs and service costs for post-construction evaluation and conducts the comparative analysis of 'percentage of construction cost method' and 'cost plus fee method.' The analysis result shows 'cost plus fee method' is more accuracy than 'percentage of construction cost method.' In particular, cost plus fee method includes various correction coefficients, such as distance, area, and integration, in order to reflect the project characteristics of each infrastructure, and suggests linear construction (roads, railways), nonlinear construction I (housing and industry complex), and nonlinear construction II (airports, seaports, dams, water and sewage).

As the FTAs' implementations are accelerated, an Ex-post assessment, such as an analysis of the tariff schedule and agricultural trade has been emerging as an important national issue for an agricultural sector Korea-EU FTA, which was to be implemented in the five years from July 2016 as one of the giant FTA. The purpose of this study was to determine the demand of an ex-post assessment on agricultural sector as a trade negotiation procedural law. In addition, by providing policy direction for the agricultural policy part requiring amendments and supplements through ex-post assessment, the conflicting arguments between agricultural and non-agricultural sector can be evaluated more objectively. The current evaluation method on the economic impact ex-post assessment of a FTA is generally compared using the change in trade balance before and after the time of FTA implementation. On the other hand, this comparison cannot be said to be the pure FTA effects and objective, tightening economic impact assessment of the FTA in all combined situations, such as the effects of exchange rates and international macroeconomic changes and climate change & occurrence of pests. Over the last 4 years, however, Korea-EU FTA's total accumulated agricultural GDP loss was measured to be 2,178 billion by these research attempts with dynamic analysis as ex-post assessment methodology. The greatest impact was mainly livestock and pork followed by cereals and vegetables. In addition, this research is expected to contribute to policy evaluations in the future.

Purpose: The purpose of this study was to investigate the changes of stress and cumulative stress in 49 people and the changes of job stress, socio-psychological stress and anxiety relief levels by conducting a survey of 85 people after Gyorae forest bathing. Methods: The level of stress was measured using the uBioMacpa, and questionnaire was conducted to derive the data. Results: In the stress level after the forest bath, the control group showed no significant and the experimental group showed a significant decrease in the bathing (p<.043). In the cumulative stress change, the control group showed no significant difference after the bathing, but experimental group decreased significantly (p<.02), and in the variance analysis, there was a significant difference between the groups, and also between the group and the before and after tests (p<.002). In the questionnaire about job stress, there was no significant difference in physical environment and job demand. Overall, in the case of job stress, there was a significant decrease (p<.001). Job autonomy, relationship conflict, organizational unfairness, inadequate compensation, and workplace culture also had a significant decrease in stress (p<.001). The social psychological stress was significantly decreased after bathing (p<.001). The state anxiety decreased significantly (p<.001) after forest bathing. Conclusions: After the forest bathing in the Gyorae forest, the stress and anxiety are both reduced and significant, providing basic information that is very helpful as a natural healing place for stress relief.
