This study examined the mediation effects of covert narcissism on the relationship between game addiction and aggression. For this study, 578 middle school boys in Chungcheong areas were included in the analysis. The results are as follows. First, correlation analyses showed that game addiction was positively correlated with covert narcissism and aggression. In addition, covert narcissism showed positive correlation with aggression. Second, step-wise regression analyses were conducted to examine the relative size that sub-factors of game addiction and covert narcissism explained aggression. It could be known that three factors of game addiction(tolerance, disregard of everyday life, damage of control) and two factors of covert narcissism(exploitation/self-centeredness, oversensitivity/vulnerability) showed significant explanatory power for aggression. Third, the Structural Equation Model was designed in which factors of game addiction and covert narcissism with significant explanatory power for aggression were included. Covert narcissism was found to partially mediate the influence of the boys' game addiction on aggression. Finally implications of this study and directions for future research were discussed.

This study attempts to investigate the spatial characteristics of private tutoring markets for adults which have been expanded rapidly with labor market changes in Korea. In particular, For the purpose, we examine thoroughly various indies of labor markets and private tutoring markets for adults in Korea in first and then analyze the spatial characteristics. We classify private tutoring institutes for adults into two categories by job-statuses and education levels, and analyze the spatial distribution patterns of the attendants of the classes. In order to understand the spatial characteristic of their distributions, we distinguish whether there exist the spatial autocorrelation or not by applying Moran's I values for each categories in first. We also examine the spatial cluster patterns by Hot spots analysis utilizing $G^*$ statistics. Multiple linear regression models are developed for each category to explain the relationships between the spatial distributions of private tutoring institutes and geographical variables.

The purpose of this research is to examine the reciprocal relationships between depression and marital satisfaction among older couples. For longitudinal dyadic analysis, this study sets up a research model based on the Actor-Partner Interdependence Model, the Common Fate Model, and Autoregressive Cross-Lagged Model. Data came from four annual waves from the 10th year (2015) to the 13th year (2018) of the Korean Welfare Panel Survey and the final sample comprised a total of 1,383 married couples over 60 years of age in 2015. Structural Equation Modeling identified the reciprocal relationship between depression and marital satisfaction among older couples, with higher marital satisfaction of older couples leading to lower depression of husbands' and wives', and with higher depression of husbands' and wives' inducing lower marital satisfaction of the couples. Thus, this study suggested that longitudinal interplay between depression and marital satisfaction can lead to a vicious cycle. Based on these findings, the need to intervene at both the individual level and the couple level was discussed in order to reduce depression and improve marital satisfaction.

The purpose of this study was to suggest implications that the level of sound financial management ability of university students could be raised, starting with the awareness that not only college students but also all financial consumers need high levels of financial management ability, such as knowledge and attitudes toward financial management, as economic conditions are in trouble in the aftermath of the ongoing Corona19. A survey was conducted on college students to achieve the purpose of the study. In relation to the research model set in this study based on the survey, financial management ability and financial self-efficacy as the independent variable, and financial management behavior as the dependent variable were selected to analyze the structural relationship according to the study model. The analysis shows that financial management ability had an effect on financial self-efficacy and financial management behavior. Based on these results, theoretical and policy implications were presented. Finally, the limitations of this study and future research directions were suggested.

The purpose of this study is to investigate relationships among scientific self-efficacy, achievement in science and cognitive self-regulation learning strategy. The subjects were composed of 158 elementary school students. Data of students' self-efficacy related to science and cognitive self-regulation learning strategy measured by questionnaire were analyzed. Science achievement scores were also collected. The results indicated that self-efficacy and cognitive self-regulation learning strategy predicted science scores. The findings showed that cognitive selfregulation learning strategy mediated the relation between self-efficacy and achievement in science. Memory learning strategy, considered a cognitive self-regulation learning strategy, did not mediate the relation between self-efficacy and science scores. The implications of science education to develop students' science achievement in the classroom and the suggestions for future researchers are discussed.

The purpose of this study was to identify the reexamination effects of behavioral activation·inhibition scale(Choi & Huh, 2010) on self-determination in order to analysis situational structure for P·E class which is perceived by students. To obtain the purpose, 656 high-school students from Gyeonggi-do area answered questionnaire using convenient sampling method. Data which is obtained through self-administration was analyzed using by the frequency analysis, multiple reguression analysis, EFA, and CFA with SPSS 18.0 and AMOS 16. Results were as followed. First, the more students have friend relation, teacher behavior, emotion change, and positive class attitude that are sub-factors of behavioral activation·inhibition, the more they have self-determination. Second, the less students have typical class structure, negative teacher's attitude, punishment, and lack of self-efficacy, the more they have self-determination. Overall results were discussed for practical application in P·E class.

This paper applies a Structural VAR approach to a 4 variable system in real GNP, M2, GNP deflator and nominal monthly earnings, disentangling 4 structural shocks, i.e., aggregate demand and supply shocks, wage pushes and various forms of regulations reinforced especially during stabilization process. Preliminary diagnostic tests confirm that the log level of each time series has at least one unit root, though the evidence is somewhat ambiguous for real GNP. One co-integration relationship is found among 4 variables, while no co-integration is found in a subsystem consisting of nomina) variables. The absence of co-integration among nominal variables strongly suggested that money is not neutral even in the long-run. The reduced form is estimated and the structural form is recovered using 6 additional identifying restrictions. Recovered structural shocks are able to capture main episodes of past 20 years, ranging from first and second oil shocks, to strong stabilization policy of early 80's and rapid wage hikes of late 80's. Overall responses of the economy to each structural shock are usually consistent with the standard Keynesian predictions, though some responses seem to be specific to Korean economic environment.

본교(本橋)는 백터자기회귀모형(自己回歸模型)(VAR)에 비하여 작성과정이 까다롭고 복잡하지만 경제구조의 파악이 용이하고 경제체계내에 주어진 충격의 해석이 분명한 연립방정식(聯立聯立方程式) 구조모형(構造模型)을 사용하여 경기순환(景氣循環)의 원인을 밝히고자 하였다. 새로 작성된 경기순환모형(景氣循環模型)은 거시경제(巨視經濟) 분기모형(分期模型)으로서 추정기간은 1972년부터 1992년까지 21년으로 통계청(統計廳) 기준의 제1순환기부터 제5순환기까지 포함하고 있으며, 경기순환(景氣循環)의 원인분석을 위해서 가상적(假想的) 시뮬레이션(counter factual simulation) 기법을 사용하였다. 본고(本稿)는 향후 경기순환(景氣循環)의 안정(安定)을 도모하거 위해서 다음의 몇가지 결론을 내리고 있다. 첫째, 건설투자(建設投資)는 경기변동(景氣變動)의 진복(振福)을 확대(擴大)시켜 온 경향이 있기 때문에 경기부양(景氣浮揚) 및 경기진정(景氣鎭靜)을 위한 정책변수로 바람직하지 않다. 왜냐하면 정부가 경기변동(景氣變動)을 감지(感知)하기까지는 시간이 걸리며, 경기변동(景氣變動)의 체감 직후 건설투자(建設投資)를 통해서 경기부양(景氣浮揚) 혹은 경기진정(景氣鎭靜)을 이루고자 하더라도 정책수립부터 정책효과의 가시화(可視化)에까지 이르는 시차(時差)로 인하여 건설투자(建設投資)가 정부의 의도와는 반대로 경기순행적(景氣順行的)인 역할(役割)을 할 가능성이 있기 때문이다. 둘째, 통화(通貨)가 생산(生産) 및 물가변동(物價變動)에 미치는 영향은 서로 상충관계(相衝關係)(trade-off) 에 있는 것으로 보이기 때문에 정부는 민간신용(民間信用) 등 통화변수(通貨變數)를 경기조절수단(景氣調節手段)으로 사용할 경우에는 사전에 정책효과(政策效果)를 충분히 고려해서 시행해야 할 것이다. 셋째 해외도매물가(海外都賣物價), 원유도입가격(原油導入價格) 및 국제상품가격(國際商品價格) 등 해외물가변수(海外物價變數)의 변동은 GNP는 물론이고 큰 폭의 물가변동(物價變動)을 초래하기 때문에, 해외부문(海外部門)의 충격에 따른 경기변동(景氣變動)을 안정시키기 위해서 정부는 유가자유화(油價自由化)를 통한 유류가격안정(油類價格安定)및 원유비양수준(原油備養水準)의 제고(提高), 해외원자재(海外原資材) 수입선(輸入先)의 다변화 등을 통하여 해외물가충격(海外物價衝擊)이 국내경제에 미치는 영향을 최소화하도록 노력해야 할 것이다.

This study investigates the relationship between mineral exports to China, North Korea's most important source of foreign currency acquisition, and its imports of various items from China from the first quarter of 1995 through to the third quarter of 2019. The results from a cointegration analysis suggest that there exists a long-run equilibrium relationship between mineral exports and imports of food, fuel, and some intermediate goods, such as industrial supplies, parts, and accessories. The results from a vector autoregression using first-differenced variables indicate that the short-run relationship between mineral exports and imports is different between the period before and after the third quarter of 2010. Prior to structural changes, i.e., before the third quarter of 2010, import shocks affected mineral exports. However, after the third quarter of 2010, an increase in mineral exports led to an increase in the import of vehicles, intermediate goods, and luxury goods. This paper shows both the possibilities and the limits that mineral exports can contribute to North Korea's economic growth. The results, which show that mineral exports have a long-run relationship with intermediate goods, such as industrial supplies, parts and accessories, imply that mineral exports to China could have a positive effect on the North Korean economy. However, the fact that mineral exports do not have any significant effect on the import of machinery and equipment, which helps the accumulation of capital formation, shows that mineral exports have a limited effect on inducing long-term growth in the North Korean economy.
