Purpose - The policy implications of free trade agreements have traditionally been a matter of debate among economists. The official signing of the Korea-China Free Trade Agreement provides economists with a quasi-natural experiment to analyze the FTA's policy effects. This article aims to more accurately understand the impact of Korea's FTA accession on the macro economy. Design/methodology - This study adopts the counterfactual method based on panel data to find common factors in the generation process of macro data to fit the counterfactual path, to accurately evaluate the effect of the macro policy. Findings - Our research results show that the signing of the Korea-China FTA has a relatively significant short-term positive effect on Korea's economic growth. On average, Korea's real GDP growth rate has increased by 2.1%. This study finds evidence in support of FTA signing not having a significant impact on Korea's GDP growth in the long run. Additionally, we evaluated the impact of the FTA on Korea's imports and exports and found that it had a significant positive impact in the short term, but the trade effect of the FTA is significantly affected by the external macro-environment. Originality/value - First, this study uses macro panel data at the national level to examine the impact of the Korea-China FTA on Korea, and more accurately describes the policy effect of the FTA. Second, our empirical results show that the Korea-China FTA policy impact is subject to occasional changes in the external environment, such as the geopolitical conflict (crisis) between Korea and China, and the US-China trade war. Finally, the analysis shows that the short-term effect of FTA is significant but the long-term is uncertain, which provides empirical evidence for the debate on whether joining FTA can promote national economic growth.

Purpose: This study is designed to test the effects of a full body massage on Apgar score, postpartum mother's childbirth experience, and mother-infant attachment for primipara during labor. Method: Data were collected using a quasi-experiment method (nonequivalent control group, pre-post test design) from November 1, 2001 to July 31, 2002. The subjects for this experiment consist of 28 women in the experimental group and 29 in the control group, out of 57 primipara hospitalized at the U OB & GYN hospital in Inchon. A 20 minute full body massage was given to the experimental group on each of three delivery phases (latent, active, and transition), and a conventional delivery care to the control group. The experimental tools for the study are Apgar score scale developed by Apgar(1958), postpartum mother's childbirth experience scale developed by Marut and Mercer(1979), and mother-infant attachment scale developed by Cropley et al(1981). The data collected were analyzed using t-test, χ2 test, and ANCOVA on the SPSS program. Result: The results of the experiment are as follows: One minute(t=6.756, p=.000; F=9.181, p=.004), and five minute(t=6.129, p=.000; F=7.918, p=.007) Apgar score are increased significantly. Postpartum mother's childbirth experience is significantly increased(t=11.691, p=.000; F=11.741, p=.001). Verbal touch score(t=5.256, p=.000; F=7.169, p=.010), skin touch score(t=11.332, p=.000; F=27.073, p=.000), and total score(t=12.105, p=.000; F=30.104, p=.000) of postpartum mother's childbirth experience are significantly increased, but not for eye touch score(t=3.236, p=.002; F=.800, p=.375). Conclusion: This study shows that a full body massage has a significant positive effect on Apgar score, postpartum mother's childbirth experience. and mother-infant attachment. Therefore, it is suggested that the full body massage might be used clinically to help primipara during labor.

This study examines the influence of fashion accessories on how men of different ages are perceived, as well as how the social values of the perceiver affect the image evaluation process. For the purpose of this study, men's accessories were limited to glasses, ties, and hats. A quasi-experiment was conducted in which 358 female university students in Seoul examined two men, one in his 30s and the other in his 60s. The social value included materialism and hedonism with higher and lower group. Factor analysis revealed three main factors with regard to men's image based on age and accessories: professionalism, morality, and preference. The findings indicated that wearing accessories can affect how men are perceived, and the perceivers' social values are at play throughout the process. Glasses enhanced a professional image in men, while ties amplified professionalism and morality. Morality and preference for the older man were heightened when he wore a fedora and a hunting cap. Taking social values into account, perceivers with a higher level of materialism associated a man with a navy blue tie more strongly with professionalism. Perceivers who possessed more hedonistic traits preferred a man wearing a cap. The subjects considered the man in his 60s as having a higher level of professionalism when he wore casual hats such as a cap or a cloche. The results of this study suggest that social values such as materialism and hedonism play a part in how people perceive men wearing accessories.

Due to the unique construction method of modular steel buildings (MSBs) with units prefabricated fully off the site and assembled quickly on the site, the inter-module connection for easy operation and overall performance of the system were key issues. However, it was a lack of relevant research on the system-level performance of MSBs. This study investigated the seismic performance of two-storey modular steel structure with a proposed vertical rotary inter-module connection. Three full-scale quasi-static tests, with and without corrugated steel plate and its combination, were carried out to evaluate and compare their seismic behaviour. The hysteretic performance, skeleton curves, ductile performance, stiffness degradation, energy dissipation capacity, and deformation pattern were clarified. The results showed that good ductility and plastic deformation ability of such modular steel structures. Two lateral-force resistance mechanisms with different layout combinations were also discussed in detail. The corrugated steel plate could significantly improve the lateral stiffness and bearing capacity of the modular steel structure. The cooperative working mechanism of modules and inter-module connections was further analyzed. When the lateral stiffness of upper and lower modular structures was close, limited bending moment transfer may be considered for the inter-module connection. While a large lateral stiffness difference existed initially between the upper and lower structures, an obvious gap occurred at the inter-module connection, and this gap may significantly influence the bending moments transferred by the inter-module connections. Meanwhile, several design recommendations of inter-module connections were also given for the application of MSBs.

Purpose: The purpose of this study was to verify effects of the Active Parenting Today (APT) program based on King's Goal Attainment Theory on parenting stress, parenting behavior, and parenting satisfaction in mothers of school-age children. Methods: This was a quasi-experimental study with a non-equivalent control group pre-post test design. Participants were 39 mothers of school-age children (19 in the experiment group and 20 in the control group) who were registered at two community children centers in G city. The experimental group received the APT program (2 hours/session/week) and telephone counseling (2 times/week) for 8 weeks. Data were analyzed using ${\chi}^2$-test, t-test, Fisher exact probability test, and ANCOVA with the SPSS/Win15.0 program. Results: Parenting stress was significantly lower in the experimental group than in the control group. Positive parenting behavior and parenting satisfaction were significantly higher in the experimental group than in the control group. However, negative parenting behavior was not significantly different between the two groups. Conclusion: The results of this study indicate that the APT program based on King's Goal Attainment Theory is useful in reducing parenting stress, creating positive parenting behavior change, and promoting parenting satisfaction in mothers of school-age children.

This paper presents a dual-algorithm search method (GWO-GSO) combining grey wolf optimization (GWO) and golden-section optimization (GSO) to realize maximum power point tracking (MPPT) for photovoltaic (PV) systems. First, a modified grey wolf optimization (MGWO) is activated for the global search. In conventional GWO, wolf leaders possess the same impact on decision-making. In this paper, the decision weights of wolf leaders are automatically adjusted with hunting progression, which is conducive to accelerating hunting. At the later stage, the algorithm is switched to GSO for the local search, which play a critical role in avoiding unnecessary search and reducing the tracking time. Additionally, a novel restart judgment based on the quasi-slope of the power-voltage curve is introduced to enhance the reliability of MPPT systems. Simulation and experiment results demonstrate that the proposed algorithm can track the global maximum power point (MPP) swiftly and reliably with higher accuracy under various conditions.

This quasi-experimental study was done to test the effects of meta-memory enhancing program for elderly women. Data were collected 12 to 30, August 2002 from 34elderly women over 65 years living in Busan city. Subjects were 15 of experimental group and 19 of control group. The metamemory enhancing program was developed by five sessions composing of 1.5-2.0 hours one session. In experiment group, this program was performed for three weeks, twice per week. The degrees of four memory performance tasks were measured using instrument of Elderly Verbal Learning Test(Choi Kyung Mi, 1988) and Face Recognition Instrument(Min Hye Sook, 1999) and the metamemory were measured using MIA questionnaire(Dixon et al., 1988). Research results are as following. 1. After participating in five times memory training programs, experimental group has the significant increase of metamemory in comparison with control group.(t=59.58, p< 0.0001). In particular, the concepts of strategy(t=20.44, p< 0.0001), achievement (t=21.94, p< 0.0001), and locus degree (t=59.58, p< 0.0001) among sub-concepts of the metamemory are increasing significantly. 2. After participating in five time memory training programs, the degree of immediate word recall(t=17.25, p< 0.0001) and face recognition(t=16.69, p< 0.0001) among four memory tasks in experimental group are increasing significantly compared with those measures of control group. Considering this results, this metamemory enhancing program was found as an effective nursing program for metamemory improvement of elderly women's memory.

Oral medication is the most frequent treatment measure for follow up treatment, which is leading by childrens' parents for them. In medication for preoperational children, they tend to concentrate the result rather than the motivation or cause. So, they frequently refuse medication which has bitter taste. So this study was attempted to develop token economy program which promote children's medication and help their parents, and to evaluate its' effect to construct the experimental ground. This study was a quasi experimental study under the nonequivalent control group posttest only design. The subjects of this study were 36 children who were aged 3-6 years and admitted pediatric ward because of their respiratory disease. Token economy program was consisted of cartoon record paper with stickers which expresses the better medication is taken the more germs die, and gift was given for back up reinforcer. To evaluate this program, time for oral medication was measured to both experimental group and control group. To determine the effect of the program, the data were analyzed by the SAS 6.12 program with t-test. The results of this study were as follows: 1. Between experimental group and control group, there was no significant difference (t=-1.2411, P=0.2374). Therefore, the hypothesis of this study was rejected. In conclusion, the token economy program for follow up care didn't change the children's behavior of oral medication. But it was found that the cartoon on recording paper gave a pleasure to participated children. Parents who were in experimental group expressed their appreciation for token economy program. So it can be said that the token economy program for follow up care was effective in inducing the children's pleasure and parents' satisfaction even though it wasn't successful in experiment. If the measuring tools for token economy program was made with well planned design and high reliability, it can be improved the effectiveness of that To develope the theoretical bases of nursing care, the well planned programs and measuring tools for them should be developed.
