The domestic ESCO project was introduced in 1992 as one of the energy efficiency improvement programs. In recent energy market, the changes in the market conditions such as smart grid, renewable energy, and the importance of demand response became important issues. As the diversified business models are required, examples of overseas exercises are examined. Business areas in Europe or the US where the ESCO industry has been active include measures to improve the efficiency of energy facilities in all areas, ranging from energy supply facilities and energy services to end users. This type of ESCO overseas business model can be classified into various types such as project execution method, supplier demand management, financing method, climate change and emission rights, new and renewable energy, and other criteria. In this study, we propose to adopt IEC (Integrated Energy Contracting) contract method in domestic ESCO market for additional business models. Current convention of listing the specific individual business types being allowed by regulation turned out to be obstacles to the revitalization of the related market. In order to achieve the goal of energy conservation, it is recommended, instead, to revise the current funding guidelines to be a negative system.

This study aimed to suggest the tasks which public support groups should fundamentally perceive and develop support models based on it so that socioeconomic activities, which have been spreading in recent years, can settle in local communities. For this aim, this study was proceeded based on Gyeonggi Province, which has established socioeconomic support center at metropolitan councils and local government councils. The demands by Gyeonggi Province residents toward the policies by Ddabok communities and local community invigoration measures have been examined through demand survey. In the analysis, characteristics and support tasks of the demands have been identified based on the survey results and six support models have been developed according to the tasks. The derived tasks are overcoming low understanding of Ddabok communities, low participation in community activities, and poor will to perform socioeconomic practices and satisfying the demand toward community activity areas adjacent to residence. Furthermore, the differences with the residents who have an experience of taking part in the Ddabok Community Project have to be overcome. Based on these study findings, this study suggested that support models of integration style and differentiated style, response to demand style and customization to capability style, and resources-focused style and resources-scattered style are necessary in order for socioeconomic communities like Ddabok communities to settle in local communities.

The growth paradigm that has led Korea for the last few decades is now reaching its critical point. Rather than focusing on the outcomes created by severe competitions of individual companies, a growth based on win-win system and solidarity focusing on public interests is more called for. In this background, I would like to examine the concept of corporate publicness and what factors consist of it. The study aims to verify a causal relationship that corporate publicness affects the corporation's social responsibility and consumers' favorability and credulity toward the company, and looks for the possibility that corporate publicness is recognized as a corporation's substantive competitiveness and an important management activity for its sustainability. The results of the study shows that corporate publicness is composed of 5 dimensions: sincerity, activeness, pursuit of public interest, harmony, and community spirit. Then the study statistically verifies that corporate publicness significantly has a positive impact on the overall evaluation results of a corporation's social responsibility. Lastly, the study confirms that corporate publicness and socially responsible activity of a company have a positive influence overall on the attitude toward the corporate brand. Based on these results, an implication is drawn that strengthening corporate publicness and its practice in action should be emphasized for a corporation to keep making outstanding performances in a sustainable way.

This study examined the experiences of the suicide crisis and recovery process by elderly women living alone to identify the essential meaning and components of life as a life to live again. In addition, the recovery of the research participants, as well as the phenomenon of such changes in thought and life, were examined. The results of this study were as follows. Data analysis yielded four components, eight sub-components, and 16 semantic unit reductions. There were four components of suicide attempts and recovery experiences of elderly women. They were "disconnection and disqualification," "repeated hardships," "road of prosperity in trouble," and "generous tolerance." The essential topics of these components have emerged not as individual but as holistic and contextually connectable topics. Finally, to summarize the results, the essential semantic structure of the suicide attempt and recovery experience of elderly women living alone is a result of a dysfunctional social structure and environment, which has placed pressure on the life of research participants. As an alternative method to overcome, they tried to solve the problem through the extreme practice of suicide attempts, but positive energy to live again due to emotional recovery factors recognized through suicide failures have made it possible to cope with the difficult reality.

This study was a qualitative study performed to understand the nature and structure of the suicide attempt process experienced by maladjustment soldiers. The survey participants targeted 10 soldiers who entered 'Camp Green' due to lack of duty by the 00 Corps of ${\bigcirc}{\bigcirc}$ Prefecture. Data were collected by individual in-depth interviews from October 2016 to September 2017 and analyzed using Colaizzi's phenomenological method. The suicide attempt process by maladjusted soldiers was delineated into four categories such as 'A prison without bars', 'Walk on eggshells', 'A pretentious series of life', and 'A life of desperation'; 9 theme clusters; and 25 themes. As a result, maladjusted soldiers had a generally negative experience related to military culture. Soldiers who fail to adapt to military culture will show extreme behavior unless they are able to overcome their depression. Unless specific understanding of the suicide attempt process is attained, the suicide prevention policies of mission-maladjusted soldiers will be ineffective. The results of this study hope to serve as the basis for a suicide prevention and nursing intervention program.

This study was carried out to evaluate the effects of initial concentration on composting of diesel-contaminated soil. Silt loam was used in this study. Target contaminant, diesel oil, was spiked at about 2,000, 4,000, and 10,000mg/kg of dry soil, respectively. Mix ratio of soil to sludge was 1:0.3 as wet weight basis. Temperature was maintained at $20^{\circ}C$ Volatilization loss of TPH was 0.7-3.5% of the initial concentrations. Volatilization loss of TPH was not increased in proportion to the initial concentration. After 30 days of operation, 86% and 94% of the initial concentrations at about 2,000 and 10,000mg TPH/kg were biodegraded. Normal alkanes were degraded more rapidly than TPH. The compounds of C12 to C14 were volatilized greatly among n-alkanes. The first order degradation rate constants of about 2,000, 4,000, and 10,000mg TPH/kg were 0.079, 0.069, and 0.061/day, respectively. Produced-$CO_2$ and degraded-TPH were correlated highly regardless of the initial TPH concentration(r = 0.97-0.99).

This study attempts to identify user perceived value as a major predictor of the usage of smartphone-based mobile commerce(m-commerce). More specifically, the study conceptualizes user perceived value of smartphone-based m-commerce along three dimensions, such as temporal, functional, and economic values. Moreover, this study proposes service ubiquity and user control that are uniquely defining characteristics of smartphone-based m-commerce and examines how the two variables are associated with the creation of user perceived value. Using a total of 164 data collected on users of smartphone-based mcommerce, we conducted PLS analysis to test the proposed model and hypotheses. The key findings are as follows : First, it has been found that the usage of smartphone-based m-commerce is determined by the three values, such as temporal, functional, and economic values. Particularly, the results show that temporal value is the most influential variable in predicting m-commerce use. Second, the results demonstrate that service ubiquity has a significant positive effect on temporal value, whereas it has no effect on functional value. Finally, user control is positively associated with temporal and functional values. Overall, the results indicate that service ubiquity and user control considerably increase temporal value, thereby accelerating the use of smartphone-based m-commerce. Discussions and implications of the results are provided.

The introduction of educational programming language has changed programming learning environment to learn programming through various learning activities. We need to analyze how effective these learning activities could be in programming learning. We performed a meta analysis of the programming learning effects according to 8 types of learning activities. The 44 studies were collected from 1993 to 2015 for the meta analysis. The study data of 77 were extracted among 44 studies through several steps. The major results were as follows. The effect size of cognitive domain was shown to be mid-level with .595 and the effect size of affective domain was shown to be mid-level with .594. We analysed according to learning activities. The effect size were no significant difference between learning activities in the cognitive domain. But simulation, animation and mathematical activities was shown to be more consistent results and mid-level effect size. Although the effect size were no significant difference, the homogeneity was shown to be high in the affective domain. The implications were suggested from research findings. First, it is desirable that learners learn programming according to various learning activity themes. Second, instructors should pay attention to simulation, animation and mathmatics activities. Third, researchers need research to find another factors for effective learning.

The purpose of this study is to explore a learning progression for integrated process skills in Earth science inquiry. For the purpose, a hypothetical learning progression (HLP) that capture how students' integrated process skills of science become sophisticated over time is developed through the literature review. This learning progression contains four components of the integrated process skills of science: designing inquiry, collecting data, analyzing data, and forming conclusion. Three hypothetico-deductive inquiry tasks of Earth science that start from recognition of the given problem to the forming conclusion are developed in order to document students' integrated process skills. A total of 126 students from middle, high, college level students participated in this study. After conducting the Earth science inquiry tasks, the integrated process skills of individual students are assessed by element based on HLP. In addition, the validation process for HLP was administered by applying the Rasch model using the students' assessment data. Finally, based on the analyzed data, the empirical learning progression (ELP) is developed by revising and supplementing the HLP. This study can help to find scaffolding methods to effectively improve the students' integrated process skills in Earth science inquiry class by identifying the factors that affect students' development of integrated process skills. It also provide implications for improving teachers' PCK of Earth science inquiry instruction.

Purpose: Despite the well-known public health benefits of vaccination, increasing public concern about the safety of childhood vaccinations has led some parents to refuse or hesitate having their children immunized. The purpose of this study was to identify the subjectivity of parents toward refusal of childhood vaccination. Methods: Q-methodology, in which subjective viewpoints are explored and analyzed using a combination of quantitative and qualitative techniques, was used. Thirty-five participants were asked to rank 42 statements on diverse issues of childhood vaccination according to a continuous 9-point scale ranging from -4 for strongly disagree to +4 for strongly agree. Collected data was analyzed using the PC-QUANAL program. Results: The results revealed three discrete groups of parents in the refusal of children's immunization: type I, distrust; type II, concern about side effects, and type III, belief that vaccinations are unnecessary. Conclusion: Special nurse counselors who can provide correct information about vaccination based on the three types should be part of the government policy. Customized education programs to shift viewpoints should be also redeveloped according to the results in this study.
