The purpose of this study is to empirically identify the influence of social entrepreneurship on the formation of entrepreneurial motivation and entrepreneurial intention. In order to effectively achieve the purpose of the study, a research model and hypotheses are developed based on the results of a comprehensive review of relevant prior literature. The research model is set as social entrepreneurship including innovativeness, risk-taking, initiative, and social value orientation as independent variables, and entrepreneurship motivation is divided into intrinsic and extrinsic motivation. For the study, data were collected from a total of 114 social enterprise-related prospective entrepreneurs and early start-ups, and a research model and hypotheses analysis are conducted. The results of the empirical analysis are summarized as follows. First, all four components of social entrepreneurship were found to have a positive effect on intrinsic motivation. However, it is found that innovativeness and initiative among the components of social entrepreneurship has a positive effect on extrinsic motivation, whereas risk-taking and social value orientation has no significant effect on extrinsic motivation. Second, all four components of social entrepreneurship were found to have a positive effect on the entrepreneurial intention. Third, both intrinsic and extrinsic entrepreneurial motivation are found to have a positive effect on entrepreneurial intention. Finally, in the relationship between social entrepreneurship and entrepreneurial intention, both intrinsic and extrinsic entrepreneurial motivation are confirmed to have a positive mediating effect. This study specified the factors of social entrepreneurship and entrepreneurship motivation that affect entrepreneurship awareness and behavior targeting social enterprises with differentiated characteristics from existing for-profit enterprises. And through an empirical analysis of the influence relationship between these factors, an attempt was made to derive academic and practical implications.

We investigated whether external environmental factors acted as a trigger for flowering in the draft bamboo (Sasa borealis (Hack.) Makino) blooming area of Mt. Baekwoon located in Gwangyang, South Jeolla Province. We then considered the cause for flowering, flowering patterns and life history strategies of the draft bamboo based on the investigation. There were no differences in soil, physical conditions, and light amount between the draft bamboo flowering and non-flowering areas. The precipitation and temperature of the areas in Korea and Japan where it blossomed from 2014 to 2017 were similar to the normal year values (for the past 30 years). Moreover, most of the draft bamboo died after flowering on a large scale, but some did not, or some culms were developed again. In other words, the draft bamboo bloomed simultaneously regardless of external environmental factors, and most of the culms were dead, but some were left alive. Therefore, it is considered that the flowering is triggered by the specific genes (referred as to clock genes) expressed periodically by a biological clock rather than the external environmental factors. Meanwhile, the draft bamboos generally bloom on a large scale by synchronizing with other ones in the distance but may also bloom several times separately on a small scale. It may be a kind of an insurance system established to disperse the risk of failed sexual propagation when flowering once in a lifetime. The results reveal that the long-period monocarpy of the draft bamboo has been strengthened to optimize the sexual propagation to overcome the increased environmental instability caused by the expansion of distribution of tropical bamboos and bamboo species to the temperate regions.

In this paper, we analysed RSS characteristics by external factors and presented an efficient algorithm for real-time location tracking and its hardware system. The proposed algorithm enhanced the ranging accuracy using Kalman Filter based on the RSS DB. The location tracking system that consists of the tag, AP(Access Point), a data collector(Data Receiver) with IEEE 802.15.4(ZigBee) network environment, and location tracking application that reveal locations of each tag is implemented for the test environment. The location tracking system presented in this paper is implemented with MSP430 microprocessor manufactured by TI(Texas Instrument), CC2420 RF chipset and the location tracking application. With the results of the experiment, the proposed algorithm and the system can achieve the efficiency and the accuracy of location tracking with the average error of 19.12cm, and its standard deviation of 5.31cm in outdoor circumstance. Also, the experimental result shows that exact tracking of position in indoor circumstance cannot achieve because of vulnerable RSS with external circumstance.

South Korea places the core of public education in school education, and textbooks are compiled based on curriculum announced by the Education Ministry. Therefore, the compilation of high-quality textbooks is very important and requires more than just revising the curriculum. Korea had been working on developing textbooks several times, but it has been evaluated as a uniform textbook in terms of external system and editing design compared to advanced foreign textbooks. This can be said to be the result of the based to only the textbook's internal system, which should be dealt with in the textbook when compiling the textbook. The textbooks which were developed at seventh curriculum were made remarkable changes in the history of South Korea textbooks. In this study, we want to examine the nation's state-authored textbooks, from the seventh textbook to the current textbook in 2015 by order of magnitude and to give a careful look at what aspects of the changes are being made. To this end, the composition of textbooks is analyzed by dividing them into external and internal systems. The external system of textbooks focuses on changes in plate form, shape, lipid, color, and illustration, while the internal system focuses on changes in the composition system of the unit, the composition system of the contents by lesson, and the style of question. As a result, we led to a significant conclusion on the changes in textbooks.

The slope collapse can be classified into internal and external factors. Internal factors are engineering factors inherent in the formation of slopes such as soil depth, slope angle, shear strength of soil, and external factors are external loading such as earthquakes. The external factor for earthquake can be expressed by various values such as peak ground acceleration (PGA), peak ground velocity (PGV), Arias coefficient (I), natural period (T_p), and spectral acceleration (S_aT=1.0). Specially, PGA is the most typical value that defines the magnitude of the ground motion of an earthquake. However, it is not enough to consider the displacement in the slope which depends on the duration of the earthquake even if the vibration has the same peak ground acceleration. In this study, numerical analysis of two-dimensional plane strain conditions was performed on engineered block, and slope responses due to seismic motion of scaling PGA to 0.2 g various event scenarios was analyzed. As a result, the response of slope is different depending on the presence or absence of sliding block; it is shown that slope response depend on the seismic wave triggering sliding block than the input motion factors.

This study explores the concept of Study Time Management Service(STMS) and the characteristics of gamification elements in STMS, in order to propose the meaning of psychic anti-entropy and the role of a meme as a new gamification element. The goal of gamification in education is to enhance study motivation and lead to flow by integrating similarities between game and study into the study environment. STMS also aims at such a goal. However, it differs in that the external anti-entropy environment, such as blocking apps, is connected with game mechanics or game thinking to give extrinsic motivation. It is also unique in that it uses a meme as a new gamification element to induce intrinsic motivation. In particular, a meme as a kind of guideline for performing study activities induces intrinsic motivation to imitate good study patterns and offers the driving force to sustain psychic anti-entropy state. Therefore, gamification in STMS is to strengthen the external anti-entropy environment by utilizing game mechanics or game thinking, and to maintain the psychic anti-entropy state by utilizing a meme of study patterns.

This paper aims at figuring out specific characteristics of affective attitude of gifted and talented in information, predicting follow-up activities and desirable direction of learning. Based on the analysis of this paper as educational directions and suggestions for elementary gifted and talented students in information are as follows: First, in gender ratio of gifted and talented in information, including the fact that ratio of boys is high, there remain the previous prejudice of higher information capability and it seems that girls who depend on external factors, parents and teachers should make more efforts to help girls trust their own capability in information science and lead them to give more value to attribution of efforts for achievement in information science. Second, as grade is higher, motivation to learn information science and attitude for success in information science among sub-elements of attitude to information science, motivation to seed positive recognition to higher graders is required. Third, in screening and selecting gifted and talented students in information, attitude to information science should be considered as main cause and the existing gifted and talented students in information should be prompted to improve their attitude to information science with value on effort for information science.

The purpose of this study is to identify the impact of well-being-oriented activities of university students in liberal arts and physical education classes on happiness. First, among well-being-oriented activities, females are more likely to have eco-friendly behavior, well-being-oriented, hobby-orientation and exercise orientation, and males are more likely to be better at purchasing well-being products and mental health. Happiness was found to be higher in boys than in outer happiness, self-controlled happiness, and inner happiness. By grade, there was no difference between men and women in well-being activities, and the happiness showed that the second and third grades were higher than the first grade, while the second and third grade were higher in inner happiness. The happiness level showed that the number of students who attended three sessions showed higher level of happiness. Second, among the well-being activities of students in liberal physical education classes, external happiness shows in hobby-orientation, mental health and exercise orientation. Self-regulating shows in well-being meal, hobby orientation, mental health. Inner happiness shows in well-being meal, hobby orientation, mental orientation and exercise orientation.

This study examined the factors affecting the team identification of professional baseball fans. The factors were divided into the fan factor, game factors, and other factors. For the analysis, two investigators visited stadium three times in total and a total number of 297 spectators were sampled using a convenience sampling method from three baseball teams. For the fan factor, a fan who began supporting his/her team from childhood or after childhood was used as a dummy variable. The interaction effects between the fan factor and other variables were investigated to offer a stereoscopic understanding about the role of kids marketing. In addition, three game factors and four non-game factors were analyzed. The results regarding fan variable and interaction effects were obtained. Fans from their childhood have much stronger team identification, and show interaction effects with the players. Regression analysis revealed player, promotion and fan service, price, and regional connection to have positive relations with team identification. This study is especially meaningful in a sense that it has proposed positive results regarding marketing to children, and the results will contribute to both the academic field and the industry.

The study in this paper, which is part of a bigger study investigating non-cognitive characteristics of Korean students at the 4-12 grade levels, aims to identify the influential characteristics that explain students' decision to give up on mathematics learning. We consider seven non-cognitive student characteristics: value, interest, attitudes, external motivation, internal motivation, learning conation and efficacy. Data were collected from 21,485 Korean students, and were analyzed with a logistic regression method using SPSS. The findings show that efficacy was the most significant indicator of students' decision to give up on mathematics learning in all three grade level bands: elementary (4th-6th), middle (7th-9th) and high (10th-12th). In particular, the causal model analysis shows that students who highly value mathematics tend to have stronger internal and external motivation, which bring about stronger interest and learning conation, which in turn lead to positive attitudes and strong efficacy regarding the learning of mathematics. It was further found that while external motivation was a significant indicator of upper grade level students' decision to give up on mathematics learning, it was only a moderate indicator for lower grade level students. The findings of this study provide useful information about which non-cognitive areas need to be focused on, in what grade levels, to help students stay on track and not fall behind in learning mathematics.
