Self-efficacy has been extensively evaluated, but no studies have investigated the effect of self-efficacy on the self-reliance of women in poor-households economic productivity. This study analyzes self-efficacy as a personal factor, learning processes, and social support as an environmental factor towards the achievement of self-reliance in women from poor-households in productive economy businesses. Despite the dominant logic of this scheme, there is a need for field-based data regarding whether the variable really supports the sustainable empowerment of poor-households women. This study used the quantitative method through the survey technique. The samples of this study included 250 people collected from five regencies in Indonesia by using a multiple-stage random sampling. The data were analyzed with structural equation modeling. The results show that social support has a significant positive impact on the learning process; social support has a direct negative impact on self-efficacy. The learning process has a direct positive influence on self-efficacy, while social support has a non-significant impact on self-reliance. The learning process has a direct influence on self-reliance. Social support and the learning process both have significant positive impact on self-efficacy. Social support, learning process, and self-efficacy simultaneously have a positive impact on self-reliance in productive economic activities.

The purpose of this study was to develop an education for sustainable development(ESD) program using community resources in Paju and to investigate the influences on ESD competencies of 6th graders. The community resources used were Unjeong lake park, environmental circulation center, environmental management center, currency museum, butterfly museum, experience center for peaceful unification, Yulgok arboretum, and Jangsan observatory. The newly developed program was related to creative-experience activity and composed of 15 sessions for 6th-grade class in elementary school, including all of the environmental, economic, and social aspects of ESD. Two classes of the 6th grade were divided into the experimental group and the control group. The results to examine the effects of the program were as follows. First, it was proven that ESD program using community resources did not help improving the perception and function competencies of learners except for the thinking abilities. Second, it contributed to the improvement of learners' attitude competencies, especially in self-reflective attitude and other-oriented attitude. Also, according to in-depth interview, the students were constantly developing their values for sustainable development, reflecting their thoughts and behaviors in a reflective way and improving their attitude toward life.

The application of appropriate technologies in a developing country is an opportunity to introduce green technology which may lead people to imagine a better life. This point is at the intersection of appropriate technology and sustainable development. This research focuses on Hatphain village where there is no clean water, sewage system, or power lines. Two environmental technologies (an unpowered water purification system, Ongdalsaem and an eco-toilet system, BeeVi toilet) were introduced, based on the concepts of the environmental self- sustainable village and feces Standard Money (fSM). We found that the Ongdalsaem was effective in reducing the concentration of nitrogen and lead in the water in Hatphain. The BeeVi water-free toilet was installed, allowing urine and feces to be separated and used as compost. We strived to spread ideas of sustainability using new eco-circulation experiences and encouraging learning about environmental technology through practical and playing facilities that residents managed themselves.

The theme-type self-harvest concept proposed in this research will be applied as a relevant reference in planning and realizing urban-rural exchange facilities at the village level. The aim of this paper is to describe the concept, to characterize the self-harvesters and organic farmers involved, to illustrate the ecological, economic and social interaction and the possible constraints of the concept. What is more important, however, is to develop programs for consultants, organic farmers and green-minded consumers, to vitalize direct transaction. The proponents of self-harvest are convinced that this concept leads to ecological, economic and social benefits, which will help to design a sustainable food supply system for small, medium and large cities.

Everything in the world is becoming connected and interactive due to the Internet. The future of interactive smart environments such as smart cities, smart industries, or smart farms demand high network bandwidth, high network flexibility, and self-organization systems without costly hardware upgrades, and they provide a sustainable, scalable, and replicable smart environment backbone infrastructure. This paper presents a new Hybrid Software-Defined architecture for integrating Internet-of-Things technologies that are essential technologies for smart environments. It combines a software-defined networking infrastructure and a real-time distributed network framework with an advanced optimization to enable self-configuration, self-management, and self-adaption for providing seamless communication and efficiently managing a vast number of smart heterogeneous devices.

Preventing the infiltration of rainwater into the landfill site is the main purpose of the final cover in landfill sites. Compacted clay layer or geomembrain have been used as a conventional landfill final cover. But they have several disadvantages when damages might occur due to puncturing, differential settlement and desiccation or freeze and thaw. For this reason, as an alternative method SRSL(Self Recovering Sustainable Liner) has been developed. Adopting the precipitation reaction of two chemical material, by forming precipitates that fill the pores, and lower the overall permeability of the liner. The advantage of this method is that when fracture of the liner occurs the remaining reactants of the two layers form precipitates that fill the fracture and recover the low permeability of the liner. In this study, the recovering ability of the SRSL with a crack due to the seasonal variation or differential settlements was investigated by permeability tests. And in order to estimate the durability of the SRSL after freeze/thaw and desiccation, uniaxial compression strength tests were performed.

Purpose: The purposes of the study were to evaluate dietitian's practices for sustainability management and identify barriers of sustainability management at school foodservice. Methods: A total of 220 dietitians working in Daejeon and Chungnam area were surveyed. 187 responses were analyzed for the study. Data were analyzed using SPSS Windows. Results: The respondents were 36% in their 20 s, 38% in their 30 s, 39.6% in elementary schools, 33.7% in middle schools and 26.4% in high schools. Among dietitian's practices for sustainability management, the item with the highest self-evaluation was purchase eco-friendly food (3.75). The category with the highest score was procurement (3.52), by waste management (3.48), production (3.39), menu management (3.36), facility and energy management (3.20), personnel management (3.18), and nutrition education (3.04). In the area of menu management, production management, facility and energy management, nutrition education, and personnel management, scores of elementary school working dietitians were the highest, followed by middle school and high school (p<0.001). The most perceived factor for barriers to sustainability management was principal's indifference to sustainability management (4.10 out of 5 points). ietitian's sustainability management practices and barriers showed a negative correlation. Conclusion: It is necessary to dietitians, employees, and principals' awareness about sustainability management in order to perform effective sustainable management school foodservice.

A sodiume-water reaction takes place when high-pressured water vapor leaks into sodium through a tiny defect on the surface of the heat transfer tube in a steam generator of the sodium-cooled fast reactor. The sodiume-water reaction brings deterioration of the mechanical strength of the heat transfer tube at the initial leakage site. As a result, it damages the crack itself, which may eventually enlarge into a larger opening. This self-enlargement is called "self-wastage phenomenon." In this study, a simulant experiment was proposed to reproduce the self-enlargement of a crack and to evaluate the mechanism of the self-wastage. The damage on the surface of the crack was simulated by making the neutralization reaction with hydrochloric acid solution and sodium hydroxide solution. A numerical investigation was carried out to validate the feasibility of the approach and to determine experimental conditions. From the computation results, it is observed that when 5M HCl is injected into 5M of NaOH with 0.05 m/s inlet velocity, the temperature at the surface near the crack increased over 319.26 K. The computational results show that the self-wastage phenomenon is capable of being reproduced by the simulant experiment.
