This research primarily aims at analyzing major crises originating from marginalizing population, especially in counties. In addition, based on the system dynamics approaches, it pays attention to divulging causal loop structure which has been rather strengthened by diverse interactions among key variables. Judging from simulation works, even though Korea is exposed to unprecedented aging trends over decades, its counter response seems inadequate and insufficient, mostly dismissing a series of impact embedded in the aging dynamics. This research statistically confirms that demographic marginalization trends have already begun in the villages within Eup and Myon counties. Furthermore, this research pinpoints out the fact that it would be almost impossible for majority of villages within Eup and Myon counties to escape from going out of existence in the course of time, as they tend to be entrapped vicious cycle of marginalization or extinction.

The purpose of this study was to investigate the causal resationships between children's learned helplessness, self-evaluation and the home environment which included the family's socio-economic status, parent's achieving pressure and maternal child rearing behavior. The results were as follows; The socio-economic status of home influenced on the parent's achieving pressure, maternal child rearing behavior and children's self-evaluation, but didn't influence children's learned helplessness. Parent's achieving pressure had a negative correlation with the maternal child rearing behavior and influenced children's learned helplessness, but did not influence children's self-evaluation. Maternal child rearing behavior influenced children's self-evaluation, but did not influence children's self-evaluation. Maternal child rearing behavior influenced children's self-evaluation, but did not influence children's learned helplessness directly. Children's self-evaluation had the strongest direct impact on children's learned helplessness. This was found to be a mediating factor between home environmental factor and children's learned helplessness.

The purpose of this study is to examine the causal relationship between the exchange rate and economic growth, and to induce policy implications. In order to test whether time series data is stationary and the model is fitness or not, we put in operation unit root test, cointegration test. And we apply Granger causality based on an error correction model. The results indicate that uni-dierctional causality between exchange rate and economic growth is detected. Exchange rate impacts on economic growth, but economic growth don't impact on exchange rate. The analysis of impulse reaction function shows that the impulse of exchange rate impacts on Korean economic growth in negative direction. We can infer policy suggestion as follows: The fluctuation of exchange rate much affects economic growth, thus we must make a stable policy of exchange rate to continue economic growth.

Domestic construction materials market was about 65 trillion won and it occupied 45% level of total construction cost by 2007. In addition, due to the recent rapid rise of crude oil and iron ore price, fluctuation of raw material cost has a great influence to the cost of construction industry. This means that smooth performance is closely related to construction materials. And among them, because of high putting rate of metal materials, it can be seen that the fluctuation of metal material prices is an important variables. So in this study, for the pre-study to analyze the impact of metallic material prices to construction cost, the researcher analyzed a causal relationship between metal material prices and construction cost.

Construction Performance measurement and management has been interested by construction practitioners. However, current construction project management practices are related to short-term improvement plans rather than long-term and systematic approaches based upon performance analysis. AR a result, there is a need for developing of a collaborative plan over project life cycle. Therefore, this paper reviews extensive literature and proposes the construction performance estimating model using a system dynamics. The paper proposes casual maps for planning, design, procurement, and construction phases. Each casual map includes all performance indicators and factors that impact on performance directly or indirectly. These casual maps that were developed by system thinking will enhance the understanding of the relationships among performances and factors. After further data gathering, these models can be used to estimate construction performance and eventually these will save project costs and shorten project schedule.

Purpose - This study aims to analyze consumer in the multidimensional aspect of a combination of corporate image and brand personality in order to identify the structural causal relationship between consumer choice and corporate image and brand personality. Design/methodology - This study combined theoretical literature studies with empirical field studies using questionnaire survey methods. To achieve this objective, a hypothetical causal model consisting of three potential variables and nine measurement variables was created based on prior research, and a structural equation model was used to identify the suitability of the model. Findings - The hypothetical model established by this study was judged to be generally appropriate. In particular, corporate image was shown to have significant static direct effects on consumer choice and brand personality. It was also shown that brand personality had a direct static effect on consumer choice, and that corporate image has an indirect significant impact on consumer choice by moderating brand personality. Originality/value - Previous papers have mainly focused on one-dimensional studies of various images, such as companies and brands. However, this paper used a model that analyzed consumer choice through multi-clue information rather than corporate images as the only clue to consumer choice.

In this study, we empirically examine the impact of win-win growth effort of domestic large firms on their financial performance. Specifically, we classify the financial performance into three aspects such as profitability, stability and efficiency, select corresponding financial ratios to each aspect, and analyze the causal relationship between the firms' win-win growth effort and each of the financial ratios. In addition, we figure out the impact of the firms' win-win growth effort on their stock rate of return. From the analysis, we show that the win-win growth effort has a positive impact on the firms' profitability, stability and stock prices; however, it does not give statistically significant impact on the firms' efficiency with even negative impact on it. These results imply that the firms' win-win growth effort could bring about inefficiency in their business operations, but the effort could increase the firms' profitability and make their financial structure more stable. Furthermore, the effort could enhance the firms' image of leading CSR (corporate social responsibility), which in turn increase their stock values.

In this study, based on previous research on personal broadcasting, we indirectly measured content quality, YouTuber attributes, user satisfaction, and behavioral intention, which are latent variables that cannot be directly measured, as measurement variables, and then measured theoretically between the latent variables. In order to analyze the causal relationship, we used a structural equation model to determine to what extent the content quality of the YouTube mukbang channel and the YouTuber's attributes influence behavioral intentions such as purchase, recommendation, and continued use according to viewers' satisfaction with use. We intend to analyze and verify the relationship between related variables. The research results are as follows. First, the value, relevance, timeliness, completeness, and data quantity of content quality were found to have no significant impact on user satisfaction. Second, the trustworthiness, expertise, attractiveness, and intimacy of YouTuber attributes were found to have a significant impact on user satisfaction, but the similarity of YouTuber attributes did not have a significant impact on usage. Third, user satisfaction was found to have a significant impact on behavioral intentions and purchase intentions. However, user satisfaction was not found to have a direct significant impact on recommendation intentions or continued usage intentions.

폭염의 발생 메커니즘은 대부분 종관 규모적 관점에서 연구가 이루어지고 있으나, 폭염발생 이전의 또 다른 자연재해로 인한 연쇄적인 영향을 해석하기 위한 연구도 중요하다. 본 연구에서는 폭염 발생 이전에 나타나는 가뭄과의 인과관계 및 영향을 평가하기 위해 부분최소제곱 구조방정식 모형(PLS-SEM)을 이용하였다. 1974년부터 약 46년간 발생한 여름철 폭염에 미치는 계절별 가뭄의 영향정도는, 겨울철 서울(경기)지역은 37%, 강원지역은 21 %, 충청지역은 17 %이며, 봄철 서울(경기)지역은 29 %, 강원지역은 18 %, 충청지역은 8 %이며, 여름철 서울(경기)지역은 22 %, 강원지역은 29 %, 충청지역 38 %로 확인되었다. 이는 지역별로 나타나는 폭염과 계절별 가뭄이 미치는 영향의 정도가 다르기 때문에 따라 나타나는 결과로 해석된다. 여름철 가뭄-폭염 간의 영향이 크게 나타난 강원, 충청 지역은 서울(경기)지역에 비해 가뭄-폭염으로 인한 피해양상이 복합적으로 나타날 가능성이 있다.
