Recently, the domestic e-commerce market has achieved remarkable growth through the spread of e-commerce throughout the industry. Nevertheless, the ratio of e-commerce use by our small and medium-sized enterprises has turned out to be very low. The reason for this low participation rate of SMEs in B2B e-commerce market is due to various reasons, but also the lack of empirical performance measurement and evaluation considering the characteristics of B2B e-commerce market in which SMEs participate. Therefore, this study was intended to analyze the effectiveness of B2B e-commerce use of B2B e-commerce to companies that are provided in conjunction with e-Marketplace by public credit guarantee agencies with experience in use. To this end, 14 items related to finance derived through prior research were used to conduct management performance analysis and hypothesis verification from a financial perspective. The implications of this study are expected to be that an empirical performance analysis from the financial perspective of a B2B e-commerce guarantee Utilized company can be used as a basis for policymaking for the activation of the B2B e-commerce guarantee in the future, thus contributing to the establishment of a stable business environment by supporting the expansion of e-commerce by small and medium-sized businesses.

Gamification is receiving much attention from a variety of fields of life as it has tremendous potential to help people get experienced with 'fun' by the elements of game mechanism and thus attract their voluntary participation eventually to reach the state of 'flow'. Some studies examined this process with a focus the relationship between game elements and flow while others regarded the game elements as fun elements and discussed the relationship between fun and flow. However, starting from the fact that the fundamental reason humans play a game is for fun and fun is in turn induced through game elements, our study defines fun as an emotion and uses it a factors are also introduced as control variables for the study on the belief that game elements affecting fun will apparently vary depending on the cultural dimensions. This study confirms that difference exists in correlations between game element, fun, and flow, depending on the different cultural settings. By comparing samples from Korea and Austria, each representing the east and the west respectively, it was found that 'social fun' affects flow and both 'relationship' and 'reward' are in turn affecting social fun in case of Korea. On the other hand, Austrian case reveals that cognitive fun affects flow and game elements affecting cognitive fun are 'story' and 'reward'.

The purpose of this study is to understand the effect of The Model of Phases of the Moon on conception changes for preservice teachers. The researcher interviewed two preservice teachers under the agreement with them on their participation in the research just before he performed a class using The New Model of Phases of the Moon. The post-interview with the same content as the pre-interview was preformed one month later. The main content of the interview is as follows; 'Explain the shape of the Moon by drawing it.', 'Explain the relative different position among the Sun, Earth, and Moon depending on phases of the Moon by drawing them.', 'What do you think of the cause of phases of the Moon?', 'Draw a picture to explain why we always see only one side of the moon.' The results of the research are as follows. First, the class with New Model of Phases of the Moon was able to perceive the relationship of Sun, Earth, and Moon in three-dimensions rather than in two-dimensions and it helped to change their misconception that the Moon's shadow causes the Moon's shape. Secondly, the class with New Model of Phases of the Moon helped preservice teachers understand better the different positional relationships among the Sun, Earth, and Moon depending on the Moon shapes. Third, the class adopting the New Model of Phases of the Moon help preservice teachers form scientific conceptions on the causes of phase change of the Moon. Fourth, the class with the New Model of Phases of the Moon is not appropriate for explaining the reason why only one face of the Moon is seen. Based upon the results above, the researcher realized the limitation of this model and suggested that this model would help learners understand phase change of the Moon and increase space perception ability.

The court-mandated spouse abusers with drinking problems not only resist and complain about taking the court-mandate but also have the low motivation to change their problem drinking and violent behaviors. Therefore, in this study the program is developed to decrease violent behaviors of spouse abusers with drinking problems. Also, the usefulness of this program is examined by quantitative and qualitative methods. The results are as follows: The experimental group's pre-to-post variation is decreased by significant level statistically more than the comparison group's variation in drinking problems. Regarding violent behaviors among groups, the experimental group's pre-to-post and pre-to-followup variation are decreased significantly. It is assumed that Motivation Enhancement Therapy(MET) influences the differences of motivation to change violent behaviors in both groups. The reason is that MET is considered to have influences on the group's dynamics and interaction. Also, it is helpful to change the negative emotions to the positive emotions and to stimulate the group interaction and the participation. This study will be contributed to promote the speciality on providing services for family in a domestic violence in Korea. Through this study, I suggested future implications in research, practice, and political side on spouse abusers with drinking problems.

In this study, a student participation-centered class based on student mathematical thinking as a the meaningful subject was called a student thinking-based math class. And as a way to support these classes, I paid attention to lesson design. For student thinking-based mathematics classes, it is necessary not only to anticipate student thinking and teacher feedback, but also to plan in advance how to properly arrange and connect expected student responses. The student thinking-based lesson design template proposed in this study is a modified three-step(introduction, main topic, summary) lesson design template. The reason for revising the existing design template is that it has limitation that it cannot focus on mathematical thinking. Using the conceptual framework of student thinking-based mathematics lesson as a lens, the difference between the three-step lesson design prepared by pre-service teachers and the students' thinking-based lesson design prepared by the same pre-service teachers was analyzed. As a result of planning lessons using the student thinking-based lesson design, more attention was paid to the cognitive and social engagement of students. In addition, emphasis was placed in the role of teachers as formative facilitator. This study is of significant in that it recognizes the importance of classes focusing on students' mathematical thinking and provides tools to plan math classes based on students' thinking.

The study was conducted to understand the meaning of the voluntary service experience of Korean-Chinese who living in South Korea and examine the reason of participating in voluntary activities. 8 people participated in the study, who come from volunteering groups in a Korean-Chinese compact community. Data were collected through in - depth interviews and participation observation. The collected data were categorized and analyzed according to Giorgi's hermeneutic phenomenological research method. As a result of the analysis, three sets of themes were drawn on the nature of their volunteering experience. Through their volunteer activities, they have been improving their images that have been damaged and stigmatized by the mainstream society. Through their volunteer activities, they have improved their self-esteem, got more information about the society and better adapted to Korean society. Moreover, through their volunteer activities, they have increased their sense of responsibility for Korean society and redefined their position in Korea. Given this, they expect the possibility of becoming a global citizen for the future. The meanings of volunteer experience of Chinese Koreans have been examined and discussed in this study, which indicated that the activation of the volunteer activities of migrants contributes positively to the integration of multicultural society.

Affective characteristics have been consistently emphasized in mathematics education, but students' confidence or interest in mathematics has not changed significantly. This study analyzes the factors affecting the affective characteristics according to students' academic achievements, which have not been studied so far. The study was surveyed 593 students in the 5th and 6th grades, divided into school mathematics education and social-environmental factors. As a result of the study, students cited 'mathematics class at school' as the factor that had the most influence on their affective characteristics, regardless of academic achievement. Excluding 'mathematics classes at school', upper level students said that 'private education' and 'college entrance exams and jobs', had the most influence on their affective characteristics. Middle level students said that 'assessment at school' and 'private education' had the most influence on their affective characteristics. Lower-level students said that 'school evaluation' and 'mathematics textbook' had the most influence on the affective characteristics. In particular, as the academic achievement level decreased, students' participation in classes decreased rapidly. Most students said that the mathematics content they were learning was too difficult for that reason. Considering these research results, it would be effective to apply methods according to students' academic achievement to some extent in order to improve affective characteristics.

The purpose of this study was to analyse the properties of leisure activity and the life satisfaction in the case of Korea Science Academy(KSA) students and Min Jok Leadership Academy(MLA) students. The participants consisted of KSA students(male:122, female:44) and MLA students(male:71, female:113) with voluntary consent. We had achieved the following results. 1) For leisure activity, KSA and MLA's male students showed the highest ratio for participation in the sports, KSA's female students in the taste-culture activity and MLA's female students in the sight-seeing. 2) The response showed that stress treatment was the principal reason of leisure activity's need. 3) Over 50% of the male students were satisfied with the present leisure activity but 12% of the KSA male students and 14% of the MLA female 14% answered to the "unsatisfactory" or "very unsatisfactory". 4) Mental stress treatment showed the highest ratio in the response to the question asking the principal straight motive of leisure activity. 5) 75$\sim$80% students considered the leisure activity as an important means to maintain health and physical fitness. 6) Though most students participated in the activities with friends, 30% of the students answered that they participate by themselves. 7) It was shown that 51% and 40% of KSA male and female students, 40% of MLA male students and 48% of MLA female students participated in leisure Activity planlessly. 8) The average leisure time of the most students was less than 2 hours a day and Male students were observed to have more leisure time than female, and KSA students to have more time than MLA students. 9) In weekdays, KSA's male students enjoyed mostly the sport for leisure activity, but taste-culture activity showed the highest ratio in the case of MLA students and KSA female students. 10) In the case of male students, 38% of KSA and 54% students of MLA did not play computer game at all, and 70% of the female students in total did not play computer game. Also, the proper control-method was in need because the result showed that KSA's male students spent more time in playing computer game than MLA's male students did. 61% of KSA female students and 53% of MLA female students answered that they did not play compute game at all during weekends. Whereas It showed that 26% of KSA male students played computer game over 3 hours during weekends. 11) The biggest reason for being unable to participate in the leisure activity was the insufficiency of time due to homework or studying for quiz. The laziness also showed high percentage of 19$\sim$25% varying between the groups. 12) The life satisfaction of KSA male students was visibly higher(p<.05) than that of MLA male students but the significantly difference wasn't shown in the case of female students.

This study analyze the factors affecting the number of bidders in public contracts by collecting contract data such as purchase of goods, service and facility construction through KONEPS among various forms of public contracts. The reason why the number of bidders is important in public contracts is that it can be a minimum criterion for judging whether to enter into a rational contract through fair competition and is closely related to the budget reduction of the ordering organization or the profitability of the bidders. The purpose of this study is to analyze the factors that determine the participation of bidders in public contracts and to present the problems and policy implications of bidders' participation in public contracts. This research distinguishes the existing sampling based research by analyzing and analyzing many contracts such as purchasing, service and facility construction of 4.35 million items in which 50,000 public institutions have been placed as national markets and 300,000 individual companies and corporations participated. As a research model, the number of announcement days, budget amount, contract method and winning bid is used as independent variables and the number of bidders is used as a dependent variable. Big data and multidimensional analysis techniques are used for survey analysis. The conclusions are as follows: First, the larger the budget amount of public works projects, the smaller the number of participants. Second, in the contract method, restricted competition has more participants than general competition. Third, the duration of bidding notice did not significantly affect the number of bidders. Fourth, in the winning bid method, the qualification examination bidding system has more bidders than the lowest bidding system.
