  • Using a stochastic volatility-in-mean VAR model consisting of the KOSPI index, the foreign exchange rate, the government bond rate, and the credit spread, this study investigates the effects of financial market uncertainty on financial markets. We find that higher uncertainty has recessionary effects on financial markets. The effects are especially stronger in equity markets and in won-dollar exchange markets. We also find that the effects of uncertainty become stronger during times of financial market stress compared to normal times. Finally, the results imply that financial market uncertainty may potentially affect the real sector, too.

  • The purpose of this study was to investigate Korean undergraduate students' metacognitive awareness and preference of effective learning strategies. To achieve this goal, a scenario-based survey was conducted focusing on the metacognitive awareness, preference, and use of seven effective learning strategies (modality effect, static-media presentations, absence of extraneous details, testing, distributed learning, interleaved learning, generation) that were empirically supported. This study also aimed to explore the relationships between grade point average (GPA), metacognitive self-regulation, and the aforementioned variables to investigate which students know about, prefer, and use effective learning strategies. The majority of students were unknowledgeable about four of the seven strategies (modality effect, static-media presentations, absence of extraneous details, interleaved learning). Only half of the students were correctly aware of effectiveness of the two strategies (testing, generation). Moreover, students showed low preference for effective learning strategies. GPA did not show a significant correlation with metacognitive awareness and preference of effective learning strategies; however, it showed a significant positive correlation with the use of effective learning strategies. Only for a few learning strategies, metacognitive self-regulation showed a positive correlation with metacognitive awareness, preference, and/or their use. This study suggests that it is important to teach effective learning strategies to undergraduates with a specific direction of instruction. In addition, this study distinguishes metacognitive awareness from preference, suggesting that these two may reflect different constructs.

  • 본 논문은 레이더 유량계를 활용하여 영구저류지의 유입·유출량을 계측을 통해 영구저류지의 재해저감효과를 분석하였다. 2009년 이후 자연재해대책법 의거 개발사업에 대해 재해영향평가를 실시하고 개발 후 영구저류지를 설치토록 법제화하고 있다. 재해영향평가서 상 50년 빈도 강우량으로 영구저류지를 설계하고 있지만, 크기 및 형태에 대한 평가는 이루어지지 않고 있으며, 이상기후로 인해 강우강도가 높은 폭우가 지속적으로 증가하고 있어 이에 대한 평가가 필요한 상황이다. 영구저류지의 재해저감효과를 확인하기 위해 유입·유출구에 레이더 유량계를 설치하였고 24시간 강우사상 동안 발생한 유입·유출량을 확인하였다. 획득 데이터를 통해 사전재해영향검토서의 기대 저감효과 영구저류지의 실제 저감효과 비교 분석을 하였고,이를 바탕으로 저감효율을 계산하여 영구저류지의 재해저감효과에 대한 구체적 평가를 수행하였다.

  • in order to measure business performance against the programs supporting enterprises proceeding with LINC project, we have evaluated and checked satisfaction and effectiveness of the supporting programs to the extent that how well people recognize its significance and the related influence factors. For doing this, we have utilized questionnaire method and analyzed the research models and hypothesis in accordance with the variables and then verified the hypothesis. Based on the analysis, the satisfaction and effectiveness of the supporting programs was significant, resulting that the better administration system of the colleges and the enterprises participating in the programs, the higher satisfaction. According to this study, the result of the research showed that the degree of participation in the supporting program and the administration system of the colleges are the key converged influence factors to its satisfaction and effectiveness. However, so far, we have only focused on the questionnaire measuring the effectiveness. From next time on, we insist that we have to continually conduct more precise research which analyzes revenues of the participating enterprises.

  • There is growing interest in natural cosmetic ingredients as natural cosmetics become popular. As a part of effort to look for natureal cosmetic agent, seaweed Sargassums were tested for functional cosmetic agents. Effective materials were extracted from Sargassum coreanum. Sargassum hemiphyllum, and Sargassum patens by simple hot water extraction. Antioxidation, whitening, anti-wrinkle, UV absorption and anti-inflammation effects were studied for functional cosmetic agents. Sargassum extracts indicated excellent cell viability, strong anti-oxidation effect by DPPH radical scavenging activity and showed significant whitening effect from tyrosinase inhibition. However, effects of antiwrinkle, UV absorption and anti-inflammation were negligible. In conclusion, Sargassum coreanum extracts showed good possibility for anti-oxidation and whitening cosmetic agent.

  • When we estimate any organization, we can use scientific tool such as organizational effectiveness. It is very difficult to know the level of organizational goal. If you plan how to assess the effectiveness of your organization, It is a complex and difficult problem, because a few social scientist think that there are many point of view of an concept of organizational goals based on the relatively concrete concept of organizational effectiveness. Social scientist Campbell insist that it is impossible to estimate organizational effectiveness accurately. So we should develope the perfect method to measure the organization as a system, the member's self satisfaction, the efficiency of the team. To achieve a good organizational effectiveness, we should study the method of approach about organizational effectiveness. This is theoretical study and show that the concept and method of approach about organizational effectiveness.

  • This study focuses on the finding out the structural effect of consumers' cognitive age affecting consumer innovativeness due to the mediating effect of perceived easy of use of mobile and perceived usefulness of mobile. For this study, a self report survey is conducted through a structured questionnaire, and a parallel double-mediated effect analysis is performed using the process macro of SPSS for the analysis. In the study results, it is found that the cognitive age of consumers directly have a statistically significant negative effect on consumer innovativeness. In addition, in the analysis to verify the mediating effect of perceived easy of use of mobile and perceived usefulness of mobile, it is shown that perceived usefulness of mobile has a positive and significant effect on consumer innovativeness. Through this, The contribution of this study can be attributed to the fact that it analyzed the structural relationship between the perceived ease of use of mobile and the perceived usefulness of mobile in the process of consumers' cognitive age affecting consumer innovativeness.

  • The purpose of this paper is to compare the learning effectiveness of autonomous learning between on-line cyber learning using Internet media and off-line learning using printed media. In this study, each group is provided with the same learning contents and the same learning conditions. For autonomous learning the results revealed a significant difference between on-line cyber learning being not as effective as off-line learning. In order to improve the effectiveness of on-line cyber learning the negative aspects have been identified. These findings will help to improve the development of on-line learning effectiveness.

  • This study aimed to investigate the differential effects of self-relevance on framing effects. For this purpose, the participants were allocated into two frame type conditions(positive vs. negative), and asked to respond on six decision-making scenarios manipulated by self-relevance levels(low vs. high). The results can be summarized as followings. First, although self-relevance level made no significant difference in framing effects, the positive frame condition tended to induce larger framing effects than the negative frame condition. Second, no significant interaction effect between frame type and self-relevance level condition was found in the positive condition, whereas high self-relevance level condition induced smaller framing effects than law self-relevance level condition in the negative frame condition. These results indicated that although self-relevance tended to reduce framing effects, this effect can be differed in frame types.
