This study concentrates on the exploratory study about self-leadership securing autonomy and self-determination of the job performance for the employees of social welfare facilities like that the members set the goal of their jobs and solve the problems by themselves without exterior one-way interruption and control. For this purpose, this study set up the analysis model and hypothesis that the efficiency of the members' job performance can be promoted since the increasing self-leadership(behavior-focused strategies, natural-reward strategies, contractive thought pattern strategies) of the employees of social welfare facilities has a positive effect on empowerment and job satisfaction. Therefore, this study has significance in the aspect that it provides political suggestion for promoting the efficiency of human resource management by investigating the relationship between self-leadership and empowerment and job satisfaction through empirical analysis.

Learners in web-based learning environment have to keep a stronger will for their study than those in traditional learning environment. Here, this strong will can be told as learner's motivation which is emotional aspects. However, most web-based instructional designs have been based on learner's cognitive aspects. Therefore, this study focused on presenting the strategies for the design of emotional bulletin board and its concrete interfaces.

Since educating digital convergence is to unite various sciences and technologies with computer as the central figure, it has different range and methods of education. Therefore, it has problems with recommending limited conceptual information because of difficulties to standardize education plan and teaching strategies. In this paper, I propose education plan and teaching strategy system by using Spearman correlation coefficients. This system is to find a solution against disadvantage of recommending limited conceptual information by ranking relations of teaching strategies from the information based on the demand of industrial and academic fields, and then provides lists of teaching strategy information suitable for user's atmosphere and characteristics. Performance test is to compare effects of precision and recall with existing service systems. The test shows 90.4% of precision and 77.6% of recall.

This study deals with the proposition of the diversification strategy for participation contents service based on the open IPTV policy, and the strategic implication for IPTV players. This paper demonstrates implication for activation of participation contents to IPTV players with reference to differentiation of usages and needs to internet and television. Thus this paper proposes for diversification of player's competency (1) variety of production channels for contents, (2) enhanced accessibility, and (3) the strategic consistency for industrial eco-system. Moreover, this paper suggests that device differentiation for creation of demand, boosting customer satisfaction & immersion through closely interlocking contents.

Recently, control theory including stochastic optimal control and various machine-learning-based artificial intelligence methods have become major tools in the field of financial engineering. In this paper, we briefly review some recent papers utilizing stochastic optimal control theory in the fields of the pair trading for mean-reverting markets and the trend-following strategy, and consider a couple of strategies utilizing both stochastic optimal control theory and machine learning methods to acquire more flexible and accessible tools. Illustrative simulations show that the considered strategies can yield encouraging results when applied to a set of real financial market data.

Research on ways to improve e-learning effectiveness has been actively conducted due to the increased numbers of web-based e-learning learners. Of many variables related to e-learning effectiveness, self-regulated learning strategy and presence have been reported as major factors that influences academic achievement in e-learning settings. The purpose of this study was to investigate the effect of self-regulated learning strategy and presence on academic achievement in web-based e-learning. In addition, this study tried to provide useful basic data for successful support and design of e-learning by verifying the mediating effect of these variables. As a result, it was verified that teaching presence and social presence have mediating effects in the relationship between self-regulated learning strategy and perceived achievement in web-based e-learning. Moreover, subjective perception of student's academic achievement played a mediating role between learners' perceived presence and academic achievement. Through this study, it is verified that it is necessary to search for ways to improve the level of learners' teaching presence and social presence in web-based e-learning design in order to eventually improve academic achievement.

Although the e-learning system is being introduced in elementary and secondary education, incorporating it into the regular curriculum is difficult. Other problems include the lack of sessions and connection to regular courses in realistically applying project-based learning in the regular school curriculum. Therefore. this study established, applied, and analyzed the blended learning strategy to resolve such issues. Specifically, a theoretical investigation on the concept of blended learning and IT-oriented, project-based learning was conducted. The theme for learning based on integrated courses was also selected, and the 5-stage project-based teaching and learning strategy, concretized. The concretization strategy involved discussion, role division, and alternative evaluation strategy. The class progressed in formats of on-class online, on-class offline and off-class online. As a result, students experienced inconvenience since the project only lasted for a short period of time. Nonetheless, they responded positively to the effect of project-based learning in general. This study was able to suggest the possibility of applying e learning in regular school curriculum and propose the direction for digital and learner oriented teaching.

In terms of habitat conservation, it is essential to develop a habitat assessment system that can evaluate not only the suitability of the current habitat, but also the health and stability of the habitat. This study aimed to develop a methodology of habitat quality assessment for endangered species by analyzing various existing habitat assessment methods. The habitat quality assessment consisted of selecting targeted species, planning of assessment, selecting targeted sites, assessing performance, calculating grade, and expert verification. Target sites were selected separately from core and potential habitats using a species distribution model or habitat suitability index. Habitat assessment factors were classified into ecological characteristic, landscape characteristic, and species-habitat characteristic. Ecological characteristic consisted of thirteen factors related to health of tree, vegetation, and soil. Landscape characteristic consisted of five factors related to fragment and connectivity of habitat. Species-habitat characteristic consisted of factors for evaluating habitat suitability depending on target species. Since meanings are different depending on characteristics, habitat quality assessment of this study could be used by classifying results for each characteristic according to various assessment purposes, such as designation of alternative habitats, assessment of restoration project, and protected area valuation for endangered species. Forest habitat quality assessment is expected to play an important role in conservation acts of endangered species in the future through continuous supplementation of this system in regard to quantitative assessment criteria and weighting for each factor with an influence.
