Purpose: This study aims to improve nursing students’ competency through evidence-based nursing simulation education. Simulations included blood transfusion care for cancer patients, pneumothorax post-op care, and blood pressure control for hypertension care. Moreover, the study investigated the effects of simulations on anxiety, self-confidence, and student satisfaction with the learning experience. Method: Participants completed a survey on student satisfaction, self-confidence, and anxiety. A prospective, one-group, pre- and post-test design of 135 fourth-grade nursing students was used. A simulation scenario was developed according to the design. It consisted of pre-briefing, practice, serial tests, and debriefing. A simulation of three scenarios comprised blood transfusion care for cancer patients, pneumothorax post-op care, and blood pressure control for hypertension care. Twenty hours of evidence-based nursing simulation practicum consisting of three scenarios dealing with major adult diseases was conducted. Result: Students showed significant improvements over time in self-confidence (t=4.67, p<.001), student satisfaction (t=3.94, p<.001), and anxiety (t=-4.63, p<.001) after the evidence-based nursing simulation. Conclusion: Simulation of evidence-based education may be a useful and effective learning strategy. Nursing educators can design evidence-based simulation programs to improve educational effectiveness.

The effect of change in exchange rates on an economy is very important, especially, to a small open economy like South Korea. I explore whether Free Trade Agreements (FTAs) have positive influences on exchange rate-pass through import price of import market for fishery products in South Korea. Competition among FTA partners is enhanced after FTAs are effective. I expect that the extent to which are exchange rate pass-through (hereafter, ERPT) into import price of fishery products (in terms of Korea currency) would be reduced since the import market for fishery products in South Korea is an oligopolistic market. Specifically, I　investigate two research questions with six South Korea’s FTA partners─Norway, Thailand, Peru, U.S., China and Vietnam. First, whether the extent to which are exchange rate pass-through into import price of fishery products from six FTA partners would decrase in the post-FTA era; seconds, the size of reduction has a negative relation with the size of their market share in the import market for fishery products in South Korea if it decreases. The empirical results indicate that the degree of ERPT into import price from other FTA partners than Norway has been reduced after FTA, statistically and significantly; however, I do not find the evidence that the size of reduction is related to their market share. The findings in this study imply that FTAs have negative effects on producers’ economic welfare in South Korea’s fishery industry by reducing the extent to which are exchange rate pass-through as well as reducing tariff barriers.

I explore that South Korea’s major import fishery product markets-frozen hairtail, frozen mackerel, frozen pollock and frozen squid-are integrated by testing whether there is favorable evidence of the law of one price (LOP). Unlike previous studies on the LOP for fishery product markets, I assume non-zero import costs and include them in a trade model. To explore whether LOP holds for major import fishery product markets in South Korea with non-zero import costs, I utilize a non-linear time-series model, Smooth Transition Autoregressive (STAR) model with the sample periods from January in 2002 to December in 2019. I find that the behaviors of home-foreign price (i.e., import price) differentials of all four major import fishery products are non-linear depending on whether trade occurs and favorable evidence of LOP for each import market in South Korea. These findings indicate that each of South Korea’s major import fishery product markets is integrated. They imply that the supply of each major import fishery product-frozen hairtail, frozen pollock, frozen mackerel and frozen squid, and their prices are stable even if there is an economic shock on each market. When it comes to trade policy implications, the Korean trade policy including tariffs or quotas against their import countries for the four major import fishery products may not have influences on their price in the markets.

Although the main objective of Free Trade Agreements (FTA) is market integration among member countries, there are limited studies supporting this impact. Our study explores whether FTA has enhanced market integration between South Korea and its FTA partners, focusing on South Korea’s fishery product import market. We investigate two research questions concerning FTA impacts: first, whether trade costs declined when South Korea imported fishery products from its FTA partners after the FTA; second, if the speed of the convergence of South Korea-its FTA partners’price differential of imported fishery products on trade costs result to occur more quickly after the FTA. To determine these outcomes, we utilize a Threshold Autoregressive Model covering the sample periods from January 2002 to April 2017. Our findings demonstrate the effects of FTA on market integration are different among FTA partners. FTA has enhanced the market integration between South Korea and Norway, Vietnam, and Spain, respectively, but not for others. Therefore, we find positive evidence of FTA on fishery import market integration between South Korea and Norway, Vietnam and Spain, respectively.

We explore each of the three major domestic fishery product markets in South Korea- Frozen Squid, Frozen Hair tail and Dried Anchovy- to assess whether we can find evidence for Law of One Price (LOP) across the five major cities- Seoul, Dae-Jeon, Dae-Gu, Gwang-Ju and Busan. To achieve our aim, we utilize two different types of unit root tests: Augmented Dickey-Fuller (ADF) and Kwiatkowski-Phillips-Schmidt- Shin (KPSS) unit root test. In each of the three fishery product markets, we find evidence in support of LOP among several cities, which confirms that these markets are integrated to a certain extent. In particular, we find stronger evidence of LOP for Dried Anchovy market relative to the other two fishery product markets. Based on our findings, we argue that the Dried Anchovy market exhibits a greater degree of market integration across the five major cities in South Korea compared to the other two fishery product markets. The greater degree of market integration in the Dry Anchovy market is facilitated by its higher substitutability across cities; taken together these findings show that the market for Dried Anchovy in South Korea is more efficient than the markets for Frozen Squid and Frozen Hair tail.

최근 정부 및 공공기관에서 실증적 정책수행을 위해 위치기반으로 정책자료를 통합·분석하여 지도로 시각화하는 다양한 정책지도를 제작하고 있다. 현행 정책지도는 행정기초자료 및 정책수립의 근거 제공을 위해 활발히 활용되고 있으나 대국민 정책소통 측면에서는 단순 자료공개 수준에 머물러 독도지식이 없는 일반 국민이 정책지도에 내포된 정보와 의미를 직관적으로 파악하기 어렵다. 본 연구는 정책지도의 정보소통 역량을 강화하기 위한 방안으로 위치기반 정보와 지리적 시각화, 인포그래픽스, 스토리텔링을 융합한 지오인포그래픽 방법을 제안한다. 지오인포그래픽의 개념, 개발 프레임워크 및 절차를 정립하고, 타깃 사용자와 전달매체를 달리하여 제안된 방법론을 적용한 시범사례를 개발하였다. 그 결과 본 연구에서 제안한 지오인포그래픽은 지역현황을 공유하고 방대한 정책지도 자료에서 주요 정책현안과 이슈를 알기 쉽게 전달할 때 유용할 것으로 기대할 수 있었다. 또한 효과적 지오인포그래픽 제작을 위해서는 특히 정보소통에 관한 기획, 사용자 특성을 고려한 시각화와 인터랙션 도입이 중요함을 알 수 있었다.

This study examines whether or not the South Korean major fishery product import markets; Frozen Pollock, Frozen Long Arm Octopus, and Frozen Hairtail are integrated. We are utilizing the Multivariate and Bivariate Johansen Co-integration test to see if the law of one price(LOP) holds in each market or not. The empirical results show that even though import prices from different countries affect each other in each South Korean major fishery product import market, there is no evidence of LOP in any fishery product import market, which means that none of the markets are integrated. Based on these results, we could expect that the three major fishery product import markets show monopolistic competition among import countries. we would also see whether or not any country plays the role of a price leader in any of the markets. Based on weak exogeneity test results, we might expect that the United States and Malaysia are price leaders in the South Korean Frozen Pollock Import Market and Frozen Long Arm Octopus Import Market, respectively; however, we need to study more on this in the future.
