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.

자유무역협정(Free Trade Agreements)이 무역비용에 미친 영향

We explore whether Free Trade Agreements (FTAs) have positive effects on market integration between South Korea and its FTA partners. When market integration occurs among countries, trade costs between them would be lower. Since the objective of FTA is market integration, trade costs may be lower between them after FTA comes into effect. Therefore, we investigate if trade costs between them have decreased after FTA to see whether greater market integration has been achieved between them. We employ a non-linear time series model, the Threshold Autoregressive (TAR) model, to measure trade costs for some tradable goods between South Korea and its FTA partners for both pre-and post-FTA over the sample periods from January 1998 to November 2017. Also, we introduce a threshold break at the effective FTA date to test whether trade costs between South Korea and its FTA partners have significantly been reduced after FTA. We find that the effect of FTA on trade costs varies across FTA partners and products. These findings imply that the effect of FTA on market integration is not consistent across FTA partners and products.

놀이치료자의 완벽주의와 발달수준에 따른 군집별 심리적 소진의 차이

임은선 ( Lim Eun-seon ),이영애 ( Lee Young-ae ) 한국놀이치료학회 2023 한국놀이치료학회지(놀이치료연구) Vol.26 No.2

본 연구에서는 현장에서 놀이치료를 진행하고 있는 놀이치료자 259명을 대상으로 완벽주의와 발달 수준에 따라 군집을 분류한 후, 각 군집 유형에 따라 심리적 소진의 차이를 검증하였다. 수집한 자료는 SPSS 26.0 프로그램을 사용하여 분석하였다. 연구 결과, 첫째, 연구 변인 간 유의한 상관이 있는 것으로 확인되었다. 둘째, 놀이치료자(초심자, 숙련자)의 완벽주의와 발달 수준에 따라 군집을 분석한 결과 3개의 군집이 분류되었다. 셋째, 놀이치료자(초심자, 숙련자)의 완벽주의와 발달 수준에 따라 분류한 군집들 간에 심리적 소진 전체와 하위요인의 차이를 확인하였다. 본 연구는 완벽주의와 발달 수준에 따라 형성된 군집 별 심리적 소진의 차이는 완벽주의가 높고 발달 수준이 낮은 조합일수록 심리적 소진에 매우 취약하며, 같은 수준의 완벽주의 수준을 가지고 있더라도 발달 수준이 높아짐에 따라서 심리적 소진을 낮게 경험하는 것으로 확인하였다. 이는 완벽주의와 발달 수준의 조합으로 형성된 다차원적인 변인이 심리적 소진에 어떠한 영향을 미치는가를 이해하는데 의의가 있다. In this study, 259 play therapists who are currently working in the field of play therapy in the field were classified into groups according to their perfectionism and professional developmental levels. Analysis was then conducted to examine any, the differences in psychological burnout according to each group type, and the data was then verified. The collected data were analyzed using the SPSS 26.0 program. As a result of the study, first, it was confirmed that there was a significant correlation between the research variables. Second, as a result of analyzing the clusters according to the level of perfectionism and professional development of the play therapists (beginners and experts), three clusters were identified and classified. Third, the differences in total and sub-factors of psychological burnout were confirmed between the groups classified according to the perfectionism and professional developmental level of the play therapists (classified as beginners and experts). In this way, this study found that the difference in psychological burnout by cluster formed according to perfectionism and professional developmental level is that the combination of high perfectionism and low professional developmental level leaves the therapists very vulnerable to psychological burnout, and even with the same level of perfectionism, the level of professional development was higher. Accordingly, it was confirmed that they experienced low levels of psychological burnout. This is meaningful in understanding how multidimensional variables formed by the combination of perfectionism and developmental level can affect psychological burnout.

Purpose - The purpose of Inflation Targeting (hereafter IT) Policy is price stability. To see whether IT policy has positive effects on price stability in South Korea, whether or not inflation rates are less persistent after an IT policy is explored. Design/Methodology/Approach - To estimate inflation persistence for the inflation rates within and deviated from the target range of 2% ~ 4% during the period of the post-IT policy, respectively, a Threshold Autoregressive (TAR) Model with aggregate CPI and disaggregate CPIs for 20 items is utilized. In addition, I investigate whether inflation persistence is different depending on whether the inflation rates undershoot or overshoot toward the target range. Findings - It was found that inflation persistence was reduced after an IT policy. However, there was no difference in inflation persistence depending on whether inflation rates are within and deviated from the target range of 2% ~ 4% and also whether they overshoot or undershoot toward the target range. I also found that the same results from the robustness test, which set the target range of 2.5% ~3.5%. Research Implications - The findings suggest that an IT policy has a positive effect on price stability in South Korea regardless of overshooting or undershooting toward the target ranges, which means that even if there is an economic shock in South Korea, its influence on the inflation rates would be temporary.

Purpose: The Purpose of this study was to investigate the effects of the '5&6 smoking cessation program - six classes in five weeks' on the high school students' perception and smoking behavior. Methods: The data collection was done from November to December, 2006. This study was designed using nonequivalent control group pretest - posttest. Experimental group had 24 students, control group had 41 students. The '5&6 smoking cessation program' was applied to the experimental group for two hours per session during five weeks. Data analysis was done using descriptive statistics, X2-test, Fisher's exact test, Independent-samples t-test, Paired t-test, Cronbach's coefficient alpha. Results: The experimental group showed significant increase on smoking self-efficacy, stage of smoking cessation behavior change and significant decrease on daily smoking amount, dependancy of nicotine, urine cotinine level than control group. But the experimental group was not significantly changed at self-awareness, Pros. for smoking and Cons. for smoking. Conclusion: In conclusion, the results of this study showed that the 5&6 smoking cessation program, which focuses on self-awareness, is effective in adolescent's smoking cessation behaviors.

어휘제시유형이 초등영어학습자의 어휘학습에 미치는 영향

임은선(Lim Eun Sun),김지영(Kim Jie Young) 학습자중심교과교육학회 2019 학습자중심교과교육연구 Vol.19 No.22

어휘학습에 효과적인 단어 제시 유형에 관한 연구는 다양하게 이루어져 왔으나 그 결과가 일치하지 않아 많은 논의와 연구가 지속되고 있다. 이에 본 연구는 시각 정보와 범주 정보를 초등영어 학습자에게 제시하여 단어 단기학습과 기억에 효과적인 유 형을 알아보고자 한다. 초등학교 6학년 3개 반(A, B와 C반) 88명의 학생들은 어휘 제시 방법에 따라 A 집단(의미 정보만 제공), B 집단(의미 + 시각 정보 제공)과 C 집단(의미 + 시각 + 범주 정보 제공)으로 나뉘어 단어를 학습하였다. 사후평가가 단어 학습 이후 바로 시행되었으며, 지연 사후 평가는 학습과제가 끝난 3주 뒤에 시행되었다. 연구 결과로 첫째, 즉각 사후 평가 결과에서 그룹 간에는 통계적으로 유의미한 차이가 없었다. 즉 어휘 제시의 유형은 학습자의 단기 어휘 학습에 영향을 미치지 않 았다. 둘째, 지연 사후 평가의 결과어휘 제시 유형의 효과는 통계적으로 유의미하게 다르지 않았다. 그러나 결과를 세분화 하여 의미 지식의 4가지 유형으로 분석하였을때, 수동적 회상 부분에서는 의미만을 제시한 A집단이 유의미한 차이가 있었다. 셋 째, 학습자들을 상․하위 그룹으로 나누어서 분석한 결과, 상위 수준의 학습자 그룹에서는 지연된 사후 평가에서 의미와 시각정보를 제공 받았던 B집단이 주제 정보를 제공 받은 C 집단 보다 더 효과적인 어휘학습을 한 것으로 나타났다. The purpose of this study is to investigate an effective type of presenting vocabulary on elementary learners vocabulary learning and retention. Eighty eight students in 6th-grade elementary school were divided into A, B and C groups according to the vocabulary presentation methods: (A) English words + Korean meanings, (B) English words + meanings + congruent pictures and (C) English words + meanings + congruent pictures + theme. The results of this study were as follows. First, according to the post-test result, there was no statistical significance among groups. Each different type of vocabulary presentation did not affect learners short-term vocabulary learning. Second, according to the delayed post-test result, the effect of different types of presenting vocabulary did not reach statistical significance. There was a significant difference in the passive recall part, however, when it was analyzed in four types of knowledge of meaning. The group A with only English words + meanings got a higher score than group C with English words + meanings + congruent pictures + theme. Third, as for the effect of types of vocabulary presentation on learners vocabulary learning and retention based on learners level, there was statistical significance only in the retention of higher-level subjects. In conclusion, when the new vocabulary is presented on elementary learners, the types of presenting vocabulary do not have any effect on vocabulary learning.

The main purpose of free trade agreements is to reach market integration among its member countries. There are, however, few Korean studies investigating the effects of FTA from a market integration perspective. This study fills in the gap. We explore whether market integration between South Korea and its FTA partners occurs based on evidence of Purchasing Power Parity (PPP). For our analysis, we utilize three kinds of unit root tests-IPS panel unit root test, Kwiatkowski-Phillips-Schmidt-Shin (KPSS) unit root test, Dickey-Fuller generalize least squares (DF-GLS)-over the sample periods: January 1998-April 2017. We find limited evidence of PPP after FTA between South Korea and its FTA partners, but we see some evidence of market integration after the FTA, specifically, a decline in trade barriers such as tariffs, a decrease in exchange rate volatility, and an increase in trade volume. We conclude that it may be misleading to rely on evidence of PPP to assess the realization of market integration.

STAR 모형을 이용한 국내 주요 수입수산물 시장의 통합 여부에 관한 연구

임은선 ( Eun-son Lim ) 한국수산경영학회 2020 수산경영론집 Vol.51 No.4

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.

국내 주요 수산물수입시장의 통합정도: 냉동명태,냉동낙지, 냉동갈치시장을 중심으로

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.
