In this paper we attempt to read a film by Haejoon LEE entitled 'Castaway on the moon' from the Bauman's modernity perspective that draws our attention to uncomfortable problems relative to wastes and wasted lifes in the global consumer society we all live in. The so-called consumer society is a post-modern society designed according to the following two criteria: on the one hand, beauty and ugliness and on the other hand, competence and incompetence. Classified as ugly as well as incompetent in this society, the two heros in this film are condemned to live their lifes isolated. Miss Kim is confined to her small room while Mr. Kim is exiled to an uninhabited island called 'Bamsum' in the Han River. In these spaces, neither inside nor outside, they perform what we would like to call 'surplus act', using wastes at their disposal. In this paper we ask ourselves whether or not this act is able to challenge the two criteria and the solidarity of the two wasted lifes can bring about change in the consumer oriented society. As well as Bauman, Agamben will help us approach this question from a theoretical point of view.

The present work shows how the flexural displacement-induced fracture strength of silicon devices, whose back surfaces have wafer grinding-induced scratch marks, depends on the crystallographic orientation. Experimental results indicate that silicon devices with scratch marks parallel to their lateral direction (i.e. reference axis in this work) are very susceptible to flexural fracture, as compared to devices with marks which deviated from the direction. The 3-point bending test shows that the fracture strength of silicon devices having marks which are oriented away from the reference axis is 2.6 times higher than that of devices with marks parallel to the axis. It was particularly interesting to see that silicon devices with identical preferred marks even reveal different fracture strengths, depending on whether the marks are involved in specific crystal planes such as {111} or {011}, called cleavage planes. This work demonstrates that silicon devices with the reference axis-aligned scratch marks not existing on such cleavage planes can have higher fracture strength approximately 20% higher than those existing on the planes.

Titanium exhibits substantial corrosion resistance, strength, and ductility, with a specific gravity of approximately 4.5 and a melting point of approximately 1800℃. It is currently used in aircraft parts and space development. This study considered the thermal characteristics, stealth effects of infrared thermal imaging cameras, electromagnetic shielding, and electrical conductivity of Ti-sputtered materials. Base materials of different densities and types were treated using titanium sputtering. Infrared thermal imaging showed a better stealth effect when the titanium layer was directed toward the outside. The film sample presented a better stealth effect than the fabrics did. In each of the samples subjected to titanium sputtering, when the titanium layer was directed outward, the untreated sample or exposed titanium layer showed surface temperatures lower than those of the samples with the titanium layer oriented toward the heat source. Additionally, after the titanium sputtering treatment, the films conducted electricity (low resistance) better than the fabrics did. All titanium-sputtered specimens presented reduced electromagnetic wave transmission and significantly reduced infrared transmission. These results are expected to apply to military uniforms (soldiers' protective clothing to gain the upper hand on the battlefield), medical sensors, multifunctional intelligent textiles and etc.

Power can be generated from either renewable or non-renewable sources. Renewable sources are liked to maintain a strategic distance from contamination emanation and rely on upon fossil energizes which is decreasing day by day. The proposed sun powered vitality transformation unit comprises of a sun oriented exhibit, Bidirectional DC-DC converter, single stage inverter and AC. The inverter changes over DC control from the PV board into AC power and offered it to the heap which is associated with the lattice. The photovoltaic sun powered vitality (PV) is the most direct approach to change over sunlight based radiation into power and depends on the photovoltaic impact. The most extreme power point following of the PV yield for all daylight conditions is a key to keep the yield control per unit cost low for fruitful PV applications. Framework associated PV frameworks dependably have an association with people in general power matrix by means of an appropriate inverter in light of the fact that a PV module conveys just dc power. This project presents the new design, Development and Performance Analysis of a Grid Connected PV Inverter. Demonstrate that the proposed framework can lessen the Energy Consumption radically from the power board and give a solid support to the Grid.

Purpose - Today, the importance of the service industry has increased. Social welfare businesses that follow the non-profit principle have neglected the distribution of the service. However, an intangible service, when produced and consumed, has a similar service delivery system to common service distribution and social welfare. Therefore, the author has assumed the efficiency of the service delivery system of social welfare to be equivalent to the service distribution industry. Hence, various kinds of social welfare services for the prevention of elderly suicide, from the perspective of distribution, are discussed. Studies on generational relations have thus far investigated depression from parent-children conflict, and satisfaction with their lives. Studies on the relationship between family solidarity and elderly suicide by analyzing existing social problems are rare. This study investigated the effects of family solidarity between old parents and adult children upon elderly suicide by analyzing serious psychological and social problems. This study revealed basic measures for elderly suicide prevention through services that could elevate family solidarity from the perspective of social welfare service distribution. Research design, data, and methodology - The subjects were 468 elderly, 65 years or older, at 18 senior welfare centers and halls for the elderly at Seoul and Gyeonggi-do. Questionnaire surveys, excluding invalid answers, were analyzed. Convenience sampling was used from February 5, 2014 to March 5, 2014. The findings were: First, women and those having spouses with advanced educational backgrounds and social activities had primary solidarity such as contact solidarity, affectionate solidarity, functional solidarity (giving help), and functional solidarity (receiving help). In addition, those who had good health, from a subjective point of view, had more solidarity. Second, the elderly who were men and single, and who had poorer educational backgrounds thought of suicide, lacked social activities, and had poor health, from a subjective point of view. Third, family solidarity between old parents and adult children had significantly negative influence on the suicidal ideation of the elderly. Results - The study revealed the following implications. First, the preparation for old age should consider not only economic welfare but also the psychological welfare due to the relationship with children. Second, the phenomenon of elderly suicide because of a lack of family solidarity could increase national loss and have great influence upon welfare in old age. Therefore, planning of welfare services for the elderly should consider the value of relationships with children to improve the psychological welfare of the elderly. Third, the social expenses of government-oriented support for parents should be discussed from the people's point of view. Conclusions - The subjects of the study comprised the elderly at Seoul and Gyenggi-do; therefore, it would be difficult to extrapolate the findings to all the elderly in the nation. The subject visited senior welfare centers as well as halls for the elderly; therefore, it would be difficult to assume that the trends were representative of the elderly in the nation.

This study aims to inquire into the U. S. elementary school teachers' storylines for science teaching methods, scientific knowledge and interactions with students. As research subjects, two American elementary school teachers, named Christina and Melissa, were selected. As test tools, this study adopted Storyline Test and semi-structured interviews. Firstly, in regard to the science teaching method, Christina evaluated that she gradually improved her science teaching skills up to positive 6 points, starting from 2 points in the first year of teaching career, while Melissa sustained a stable state with 5 points in the 9th year of teaching career, starting from 1 point in the first year of teaching career. It was found that both the teachers had more confidence in their science teaching methods by participating in various training programs. Secondly, Christina evaluated her scientific knowledge in the first year of teaching career as 4 points, but evaluated her present scientific knowledge as stable as 6 points since she started studying teaching materials actively, discussing with other teachers and having more ability of application through science class integrated with other school subjects, in the 7th year of her teaching career. On the other hand, Melissa evaluated her scientific knowledge in the first year of teaching career as 1 point since she did not exactly know what to teach elementary school students, but in the 6th year of teaching career, she sustained a stable state with points through joint-activities with other teachers. It was found that chances to research with other teachers had important effect on both the teachers' confidence in scientific knowledge. Thirdly, in regard to interactions with students in science class, Christina said that she did not have any interaction with students when instructing inquiry activities in the first year of teaching career, but since the 10th year of her teaching career, she had sustained a stable state with 6 points through active interaction with students, by leading learning projects and science competitive exhibitions, etc. On the other hand, Melissa evaluated her interaction with students in the first year of teaching career as 1 point because her class was reading-oriented, but since the 9th year of teaching career, she had sustained a stable state with 6 points so far, by developing inquiry activity strategies to improve interaction with students. Overall, it was found that inquiry activities played a central role in improving both the teachers' interaction with students.

Current Korean innovation system is facing a new turning point while the growth-oriented and S&T provide-oriented development strategy. Accordingly, there are needs for not only system transition in various area, such as sustainable energy, agriculture, and rural area but also STI policy paradigm shift to create a new innovative pathway. Living lab is being discussed in European country as a new innovative model based on user participation and as a niche experiments for sustainable system transition. This study attempts to analyze the living lab cases which are for the purpose of energy transition, agriculture rural areas system transition, and STI policy paradigm shift. Based on this analysis, the implications were derived in Korea. European Suslab project, C@R project, and Taiwan living lab, promoted diverse transitional experiments successfully by collecting users' background and experiences from pre-planning stage and by maintaining the user-driven innovative actions within the whole development process. This result provides various suggestions to current Korean situation that central government and local governments are considering the introduction of living lab. Living lab can also be utilized as a strategic niche experiments for socio-technical system transition in region or country, as a mean of policy integration, and as a new regional innovation model. In addition, it can be an important platform to realize the policy integration reflecting the user and demand-side which are highlighted in recent innovative policy paradigm.

In the Web-based information systems, separating the business process logic from the data and presentation logic brings about a wide range of advantages. However, this separation is not easily achieved; even the data logic may be not separated from the presentation layer. So, it requires to define an model for business processes, and then to map the model into the user's dynamic interface using the logic separating strategy. This paper presents a stylesheet method to recognize the process by extending XSLT (Extensible Stylesheet Language Transformations), in order to achieve the logic separation. To do this, it provides an specification of the business process, and a scheme that extracts business model factors and their interactions using a Petri-net notation to show the business model into the process point of view. This is an attempt to separate users' interaction from the business process, that is, dynamic components of interaction Web document from the process structure of Web applications. Our architecture consist mainly of an XSLT controller that is extended by a process control component. The XSLT controller is responsible for receiving the user requests and searching the relevant templet rule related to different user requests one by one. Separation of concerns facilities the development of service-oriented Web sites by making if modular. As a result, the development of service-oriented Web sites would be very easy, and can be changed without affecting the other modules, by virtue of the modularization concept. So, it is easy to develop and maintain the Web applications in independent manner.

The purpose of this study was to investigate the awareness and practice on well-being life and well-being related behaviors, and the various factors affecting well-being related behaviors such as purchasing food materials, food habits, eating out and daily routine activities. A survey was conducted by questionnaire and on a 5-point Likert scale. The subjects of this study were composed of 221 students and their 102 parents who were over 40 years residing in the Ulsan area. The results of this study are summarized as follows: Almost half of the subjects (47.4%) responded that they have good health conditions; to keep a good health condition, 41.2% of the subjects were exercising regularly and 20.4% of them kept diet control. In regard to the meaning of well-being, 66.6% of the subjects thought it is the lifestyle for physical and mental richness (children: 70.6%, parents: 57.8%). 30.3% of the subjects answered that the most important part of well-being was food related. The importance order was mental richness, food related things, physical health for children, and for the parents, it was food related things, physical health, mental richness. Most of population (45.8%) answered that they have a willingness for the pursuit of a well-being life. Among the well-being related behaviors, 69.7% of subjects have purchased items (children: 61.5%, parents: 87.3%). 37.2% of the subjects have acquired information from TV. The average well-being practice score was $61.01{\pm}10.36$. Children's scores were significantly lower than the parent's scores (p < 0.001). And the average practice score of 'purchasing food materials,' 'eating out,' 'food habits,' 'daily routine activities' were $15.3{\pm}3.3,\;15.5{\pm}3.1,\;16.8{\pm}3.3$ and $13.4{\pm}3.5$, respectively. Among five types of purchasing food materials, 'purchasing domestic agricultural food' was greatest ($3.64{\pm}0.91$) and 'purchasing of organic or low agricultural chemical food products' was lowest ($3.15{\pm}0.91$). In regard to food habits, 'eating rice and bread made of mixed grains' was greatest ($3.46{\pm}1.12$) and 'eating uncooked food or zen food' was lowest ($2.46{\pm}0.99$). The practice scores were significantly affected by gender (p < 0.05), monthly income (p < 0.01), educational level (p < 0.01), presence of disease (p < 0.05), subjective health condition (p < 0.05), well-being awareness (p < 0.001) and concern with well-being (p < 0.001). Well-being awareness scores and well-being practice scores are related positively. Therefore various programs in well-being education should be necessary in order to boost the authentic perceptions of well-being and well-being oriented behaviors in any socioeconomic situation, such as different generations; industrial companies producing well-being goods for consumer's needs and satisfaction; and government and local community create various conditions for well-being oriented behavior.

This study was to investigate the balancing and clinical abilities trunk muscle stabilization exercise and trunk muscle resistive exercise of stroke patients having surface changes in balance of body. The subjects of this study were 30 stroke patients(15 males and 15 females) that three times a week for 12 weeks at the same time point and with the same amount of exercise. They were separated into two groups and did reinforcing exercise on trunk muscle stabilization exercise and trunk muscle resistive exercise for three times a week for twelve weeks. It were measured balancing ability, they performed functional standing balance test, functional forward arm stretching test. performance-oriented mobility assessment, berg balance scale. The balancing exercises were modified from preceding studies and consisted of 6 difference exercises. The functional standing test with open and close eyes and performance-oriented mobility assessment, the trunk muscle stabilization exercise group and the trunk muscle resistive exercise group improved significantly. The forward arm stretching was test the trunk muscle stabilization exercise group more improved. This study found that the balancing exercise on trunk muscle stabilization exercise was more effective than trunk muscle resistive exercise for stroke patients. Thus, trunk muscle stabilization exercise has more positive effects on the improvement of balancing abilities of stroke patients.
