The study abroad phenomenon at an early age in Korea is increasing steadily. Increasing social demand for global leaders, disappointment in Korean educational system and economic growth are motivating more students to study abroad. The study abroad is a social phenomenon that is widespread across all social status in Korea. This study tries to examine the phenomenon in respect to social, psychological, educational and economical perspectives and seek future research questions. The findings suggest ways to improve Korean educational system, support students currently or planning to study abroad and to re-adjust in Korea after they come back. A balanced perspective is necessary in viewing study abroad phenomenon, rather than preventing, implementing stronger pulling factors in Korean educational system. It is necessary to hold the study abroad as another educational opportunity.

In order to predict the moldability of a injection molded part, a simulation of filling is needed. Short shot is one of the most frequent troubles encountered during injection molding process. The adjustment of process conditions is the most economic way to troubleshoot the problematic short shot in cost and time since the mold doesn't need to be modified at all. But it is difficult to adjust the process conditions appropriately in no times since it requires an empirical knowledge of injection molding. In this paper, the intelligent CAE system synergistically combines fuzzy-neural network (FNN) for heuristic knowledge with CAE programs for analytical knowledge. To evaluate the intelligent algorithms, a cellular phone flip has been chosen as a finite element model and filling analyses have been performed with a commercial CAE software. As the results, the intelligent CAE system drastically reduces the troubleshooting time of short shot in comparison with the experts' conventional methodology which is similar to the golden section search algorithm.

A mixed model with a white noise process and an IMA(0,1,1) process is considered as a process model. It is assumed that the process is a white noise in the absence of a special cause and the process changes to an IMA(0,1,1) due to a special cause. One useful scheme in measuring the process level is to use the variable measurement interval (VMI) between measurement times according to the value of the previous chart statistic. The advantage of the VMI scheme is to measure the process level infrequently when in control to save the measurement cost and to measure frequently when out of control to save the off-target cost. This paper considers the VMI scheme in order to detect changes in the process model from a white noise to an IMA(0,1,1). The VMI scheme is shown to be effective compared to the standard fixed measurement interval (FMI) scheme in both statistical and economic contexts.

This study conducts the horse industry, which shows how country has implemented structural adjustment policies in order to cope with the economic shocks that an FTA brought about. Among the FTAs that Korea has made, Korea-EU and Korea-US FTAs have been regard to bring relatively big impact on korean agricultural sector. The horse industry is a very large and important part of our national and local economies. It is diverse, involving agriculture, business, sport, gaming, entertainment and recreation. The enactment of the 'Horse Industry Promotion Act' can be a turning point for the recovery of the livestock industry. The Act is meaningful in that it can be expand the horse industry as a driving force of rural growth and contribute to people's leisure life. In this context, this study aims to draw policy implications for the Korean government to promote the horse industry.

Exponential smoothing methods do not adapt well to unexpected changes in underlying process. Over the past few decades a number of adaptive smoothing models have been proposed which allow for the continuous adjustment of the smoothing constant value in order to provide a much earlier detection of unexpected changes. However, most of previous studies presented ad hoc procedure of adaptive forecasting without any theoretical background. In this paper, we propose a detection-adaptation procedure applied to simple and Holt's linear method. We derive level and slope change detection statistics based on Bayesian statistical theory and present distribution of the statistics by simulation method. The proposed procedure is compared with previous adaptive forecasting models using simulated data and economic time series data.

How do party organizations respond to newly evolving social groups? Research on Indian party organizations reveals that in multiethnic societies with uneven modernization between social groups, internally competitive parties respond better to newly evolving groups. Moreover, it is claimed: the same dynamic works vis-$\grave{a}$-vis homogenous societies with cleavages based on economic differences; and, the pattern holds regardless of differences in electoral institutions. This study examines these claims by testing whether factional competition correlated with recruitment into Japan's Liberal Democratic Party in 1972 and 1983. Japan had a single-nontransferable-vote system with multi-member districts, while the research on India assumes a first-past-the-post system with single-member districts. This study conducts a difference of means test on the population of new and old politicians in the LDP in 1972 and 1983 with a pooled variance adjustment to account for differences in populations' size. The findings show that intra-party competition and recruitment are not correlated in Japan, thus tentatively rejecting both claims.

This paper provides an empirical investigation of the determinants of current accounts utilizing an exchange rate (ER), terms of trade (NET), industrial activity (IPI), world import volume (WIM), trade share of the China and Japan (CHJP), proportion of service trade (SERV). The period examined is 1991:1 through 2010:2. It is tested under different cases such as whether variables were cointegrated and whether there was an equilibrium relationship. The result showed that the hypothesis of no cointegrated vector could be rejected at the 5 percent level. The estimated error correction model showed that adjustment speed is fast. This paper also applies impulse-response functions to get additional information by considering the responses of the current account to the shocks of economic variables. The results indicate that current account responds negatively to industrial activity and proportion of service trade, and then decays very quickly.

I compared trade structure and competitiveness by sector using industrial classification in UN Comtrade data and SITC. Based on the comparison, I calculated market share, export competitions, RCA, and TSI. and then selected sensitive industries based on competitiveness, and identified the ZOPA and our BATNA. These calculations confirmed the industries damaged by FTA and those benefiting from the FTA between Korea and Japan, the study them developed strategies for VIA negotiation. It is to minimize damages to Korean economy and to maximize benefits from the agreement. The negotiation plan allowed an adjustment period for industries, for which damages are expected, by setting a long grace period before implementing tariffs. Based on the negotiation plan made through economic analysis, I intend. contribute to more efficient promotion of negotiation by extracting the optimal FFA negotiation plan for each manufacturing industry.

The SGR system which is the basis for setting Medicare conversion factor updates was enacted since 1992. The SGR sets a target rate of spending growth based on factors influencing medical costs. In our situation of Fee Contracts in Korea, there exist much conflicts with SGR. This article seeks how we can implement the SGR system successfully in Korea. The major points are estimation of real economic parameters, adjustment of prior estimation, consideration of important factors influencing medical costs.

In that marriage immigrant women' birth rate are higher than those of Korea women, they were selected to suggest pronatalism in Korea. The purpose of this study is to explore the child birth intention of marriage immigrant women. One of qualitative study, case study was used in methodology. Participants were 10 marriage immigrant women, depth interview were conducted. The major results were categorized facilitators and inhibitors. Facilitators were 'number of origin family members', 'absence or weakness of family planning', 'successful experience of the first child birth', 'no difficulty in childbearing', 'recommendation of mother-in-law', 'child' positive effect in Korea life adjustment'. Inhibitors were 'insufficient economic condition', 'husband' old age and the opposite of mother-in-law', 'dissatisfaction with marriage life', 'lack of government' support'. Based on this results, practical implications and interventions were suggested.
