본 연구는 사회복지조직에 대한 이미지, 신뢰성, 반응성이 개인후원자들의 후원지속성에 미치는 영향과, 조직동일시의 매개효과, 그리고 경제형편 수준의 조절효과를 실증적으로 검증하였다. 구조방정식 모형에 기초한 주요 변수들의 인과관계 분석결과, 개인 후원자들의 경제수준과 상관없이 사회복지조직에 대한 이미지, 신뢰성, 반응성은 후원지속성에 직접적으로 영향을 미치지 않은 것으로 밝혀졌다. 경제형편이 좋은 집단의 경우, 조직 이미지, 신뢰성, 반응성은, 조직동일시에 각각 유의한 정적 직접효과를 미쳤고, 조직동일시는 후원지속성에 정적 직접효과를 미쳤다. 조직동일시를 완전매개로 하여, 조직이미지, 신뢰성, 반응성 등이 각각 후원지속성에 유의한 영향을 미칠 수 있음이 입증되었다. 반면, 경제형편이 좋지 않은 경우는, 조직이미지와 신뢰성만 조직동일시에 유의한 영향을 미치는 것으로 밝혀졌다. 개인 후원자들의 경제형편 수준에 따라 후원지속성에 영향을 미치는 요인들의 직 간접효과가 상이한 양상을 보인다는 사실이 확인되어, 경제형편의 조절효과가 실증적으로 입증되었다. 잠재평균 분석결과, 경제형편 수준에 따른 주요변인들의 차이는 후원지속성에서만 유의한 차이를 보였다(평균값, .197, Cohen's D=.779). 개인 기부자들의 후원기관에 대한 동일시가 후원지속 가능성을 높일 수 있는 결정적으로 중요한 요인임을 강조하면서, 주요 발견점을 토대로 실천적 함의를 논의하였다.

According to previous studies, the effect of intrinsic motivation related variables such as cognitive absorption (CA) on the use of information technology(IT) should be mediated by the conscious intention. However, CA, which is a thought of previous emotional experience, a deep involvement with a software, may be one of environmental cues stimulating the use of IT independently of conscious intention. The objective of this study is to show the direct effect of CA on the automatic use of IT. For this purpose, as well as the relation between CA and use, two relations, CA-intention and intention-use, were also suggested as hypotheses, which will show that conscious intention would not fully mediate the relation between CA and automatic use. Moreover, for seeing the effects of CA as time passes, the proximal effect, which is short term and transitory effect, and the distal effect, which is long term and lingering, were simultaneously included in hyptheses. Finally, the effect of past use was also suggested as a hypothesis which aimed to show that automatic use would be controlled mostly by habit rather than not only intention but also CA. For the empirical validation of the hypotheses, 174 users of 'Cyworld', one of most influential social network services, were longitudinally surveyed, which showed that the hypotheses were accepted.

Development of high efficiency turbine with good performance is one of the main topics in the field of developing wave energy converter. For the development and improvement of the turbine performance, the effect of wave condition on the turbine performance should be considered in detail. Also, water depth is an important factor because incident wave power to the turbine is considerably influenced by the wave particle amplitude of motion and the amplitude is closely related with the water depth. Therefore, in this study, the effect of water depth on the performance of a direct drive turbine(DDT) for wave energy converter is investigated using the DDT which is installed in two types of wave channel. The experimental results show that the DDT captures more wave energy under the condition of relatively shallow water depth. When the water depth is shallow, the horizontal water particle amplitude of motion becomes wider and thus, the water power toward the turbine becomes larger.

The purpose of this study was to examine the relationship structure in discount store focusing on age. Subjects for this study were 360 customers who had purchased fashion products in discount stores. For date analysis, $x^2$-test and regression analysis were used. As the result, when comparing groups by the age, women in their 20s, 30s and 40s had 'relationship maintenance intention' through satisfaction, trust and commitment. In the case of women in their 20s group, the information, reputation, product salesperson and price variables had the effects on satisfaction. The information, location, salesperson variable had direct effect on relationship maintenance. In the case of women in their 30s group, the benefits, information, reputation and price variables had the effects on satisfaction. And the information, salesperson variable had direct effect on relationship maintenance. In the case of women in their 40s group, the information, location and price variables had the effects on satisfaction. The reputation variable had direct effect on relationship maintenance. Based on these results, fashion marketing strategies of discount store would be suggested.

Purpose: In the period of international integration, how is the implementation of intellectual property regulation in developing countries? Do intellectual property rights help attract more Foreign direct investment (FDI)? This study aims to show the effect of intellectual property rights, reflect in the number of patent registered (Patent distribution into two components: Patent_residents and Patent_non-residents) on FDI attraction in Vietnam. Research design, data and methodology: Using Autoregressive distributed lag (ARDL) model for the data collected from 1990 to 2018 with EViews version 9 software. Conclusions: The results indicate that the number of patent protection has a positive effect on FDI in both short term and long term. In particular, only patent registration of foreign individuals and organizations has a significant positive effect on attracting FDI, while that of Vietnamese patents is not statistically significant. From the results of this study, we provide some recommendations to help attract FDI based on raising awareness of intellectual property rights: Increase international cooperation for innovation to learn and encourage patent; Improve the capac ity of inventing as well as the ability to register patents of Vietnamese people; Government agencies are tasked to support a nd review registration procedures; Encouraging patent registration based on the patent.

This paper examines the role of distance learning self-efficacy, belief in one's capabilities of using a system in the accomplishment of web-based distance learning, in predicting user intention to use and performance of distance learning system. It used self-efficacy theory and technology acceptance model(TAM) to build a model that predicts relationships between antecedents to students' distance learning self-efficacy assessments and their behavioral and attitudinal consequences. The model was tested using LISREL analysis on the sample of 250 students who have worked with the Distance Learning System. The results indicated partial support for the conceptual model. In accordance with TAM, perceived usefulness had strong direct effects on intention to use and performance, while perceived ease of use had both direct and indirect effects on intention to use, but not performance. Distance learning self-efficacy had only direct effect on perceived ease of use to use. Computer experience was found to have a strong positive effect on distance learning self-efficacy, and computer anxiety had a negative effect on distance learning self-efficacy. Implications of these findings are discussed for researchers and practitioners.

Social media websites have continued to proliferate, and the way in which people stay connected has also evolved. The issue of user loyalty a website remains crucial given that the competition is severe. Websites need loyal users who continue to use their sites to survive and be successful. In this research, we applied self-regulation framework to investigate the factors leading to user loyalty to a social media site. In particular, the role of sense of belonging, which is a common emotional reaction to a social media site, is examined. A survey of users in a popular social media site in Taiwan was conducted. Results show that both sense of belonging and service quality have direct effect on loyalty, whereas trust affects loyalty indirectly by fostering a sense of belonging. Service quality affects loyalty through trust and sense of belonging. Notably, trust has insignificant effect on loyalty as originally proposed. Users are then classified into two groups, namely, heavy and light users, based on their usage. Among light users, service quality has no direct effect on loyalty. Therefore, sense of belonging has sole direct impact on loyalty. Both service quality and sense of belonging contribute to loyalty in users who spend more time online. Implications of this study are also discussed.

This study was conducted to evaluate the antioxidative effect and antimutagenic capacity of ethanol extracts of Flammulina velutipes by employing biological and biochemical assays. The $IC_{50}$ of MDA with BSA conjugation reaction, lipid peroxidation and scavenging effect on DPPH radical in ethanol extracts of Flammulina velutipes was found to be 28.39 mg/assay, 9.33 mg/assay and 144.61 mg/assay respectively. Therefore, the most effective antioxidative capacity of ethanol extracts of Flammulina velutipes was $Fe^+$-induced linoleate peroxidation, among the method used this study. The indirect and direct antimutagenic effects of the ethanol extracts of Flammulina velutipes were examined by the Ames test using Salmonella typimurium TA98 and TA100. The inhibition rates on indirect mutagenicity mediated by 2-anthramine and on direct mutagenicity mediated by sodium azide in Salmonella typimurium TA100 and mediated by 2-nitrofluorene in Salmonella typimurium TA98 were 0%, respectively. These findings indicate that ethanol extracts of Flammulina velutipes have no effects on indirect and direct mutagenicity. Based on these results, it believed that the ethanol extracts of Flammulina velutipes has antioxidative capacities, and is a the candidate for the prevention and dietetic treatment of chronic diseases and the development of antioxidative functional food.

The goal of this paper is to find an operating conditions of the single direct ethanol fuel cell such as the cell temperature, and flow rates of ethanol and oxygen. To investigate the output characteristics, the electrical current increased from 0[A] with interval of 0.001[A] every 2[s], and the cell voltage was increased until the voltage became 0.05[V]. Related to the effect of the cell temperature, the output characteristics both voltage and power were increased upto 80[$^{\circ}C$] according to the increase of the current density, but those were decreased over that temperature. In addition, the optimal flow rate of ethanol in anode was identified as of 2[mL/min] due to the dependence of generation rate such as the hydrogen ion and electron. And the flow rate of oxygen in cathode was desirable to about 300[sccm/min], it might be affected by the chemical reaction rate of the water formation among hydrogen ion, electron, and oxygen. Consequently, the fundamental conditions were identified in this work, and it will be carried out to find the best conditions of membrane by the effect of the plasma surface treatment, and the effect of other catalysts except for a platinum.
