  • The present paper hopes to elucidate the problem of determining if a given I-shaped cross-section is properly proportioned to accommodate sufficient plastic hinge rotation capacity to facilitate the redistribution of moments in a structural system as needed to accommodate the formation of a collapse mechanism. It might be tempting to believe that application of the limiting flange plate slenderness value for the case of major axis flexure are applicable in this case; since the pervasive belief is that this approach ought to be conservative. However, the present research study indicates that this is not the case and thus more sophisticated analysis techniques are required to better understand this case.

  • Most of us spend the greater part of our lives in the kitchen, but of all the man environments it maybe the least well-explored share commitment to a cleaner and healthier environment. It has long been kitchen system belief that the environment is a precious gift. In case of built in kitchen system, because it depend upon the earth's resources to design and manufacture steel hardware products, human beings feel an abiding responsibility to act wisely in the environmental choices we make, large and small, every day. Built in kitchen system, designed and coordinated by study of designer, represents an open, complete, free and 'focused' way of conceiving, furnishing and organizing one's own kitchen. A space rich in technical values and home warmth, where few, simple and carefully designed components distinguish and characterize the various work spaces, from the area, intended for preparing and washing food, to the cooking area, and to a wide range of multivalent pieces of furniture, wood paneled wall units and shelves.

  • Objectives: This study is to examine that drinking problems among university students were accounted for not only by student's individual characteristics but alcohol policy and environmental characteristics of the university in which students were enrolled. Method: Secondary data analysis was employed in which variables under study were derived from a raw data of a nationwide representative sample in 2009. Raw data under analysis included 3,665 students from 63 universities across Korea. Organizational and environmental characteristics of the university were collected from university administrators while individual characteristics and drinking behavior from the students in using self-administrated questionnaire. Multilevel regression analyses were employed to describe alcohol policy effects on students's drinking problems measured by AUDIT by using HLM7.0. Results: ICCs indicate that variation in drinking problem depends on alcohol policy of university. Multilevel regression models identified statistically significant factors in explaining variance of drinking problems. Group means on drinking problem are affected by indicators representing alcohol policy with level of drinking problem of student being decreased in accordance to level of availability of alcohol on campus. Conclusions: It is concluded that drinking problems among university students were associated with both individual characteristics and alcohol policy of the university they enrolled. This study supports policy belief that interventions at environmental as well as individual level are required to prevent drinking problem among university students.

  • Since the industrialization of swine production in the late 1900s, swine farms in the United States, as well as in Europe, have largely become consolidated. Pig farms became larger in size but fewer in number, with 91% of market pigs being produced by large operations with 5,000 or more pigs on-site in the US, and only 3% of the total utilized agricultural land representing organic farming. Such change in the market made it difficult for small farmers to stay competitive, forcing them to find alternative ways to reduce the cost of production and increase profit using the outdoor production system. In contrast to the indoor confinement system, outdoor production system uses pasture-based units and/or deep-bedded hoop structures that promote animal welfare and environmental sustainability with a lower capital investment. In accord with the growing concern for animal and environmental welfare and food safety by the consumers, small farmers practicing an outdoor production system are seeing increased opportunities for marketing their products in the pork niche market. Unlike the general belief that the reproductive and growth performance measures of the outdoor sows and piglets are poorer in comparison with the animals reared indoors, studies showed that there was no significant difference in the performance measures, and some traits were even better in outdoor animals. Improved reproductive and production traits can increase the sustainability of outdoor farming. Present study reviewed the recent studies comparing the performance measures, meat quality and health of indoor and outdoor animals, as well as the efforts to improve the outdoor production system through changes in management such as hut types and breed of animals.

  • This paper evaluates the historical development of national park policy and administration in Japan from the perspective of achieving sustainable development in nationally important ecological areas. Contrary to the widely held belief, the national park system in Japan has been unsuccessful in balancing conservation and development. The fundamental reasons for its failure are as follows: the Japan's national park system has been largely founded and developed based on economic grounds and held sway by economic development policy; the policy and administrative coordination between government units concerning conservation and development has not been carried out; public participation and environmental groups' involvement in the decision making have been extremely limited; national parks have been perceived in the public image not as distinctive national heritage but as finest and popular tourist sites; and the dominant interest of tourism and recreational development has prevailed over conservation interest. Japan's unsuccessful experience and lessons imply that there is urgent need to drastically reform our national park system, largely founded on the Japanese model, in order to save our last national environmental heritage.

  • The general aspects for the future warfare shows that the concept of firepower and maneuver centric warfare has been replacing with that of information and knowledge centric warfare. Thus, some developed countries are now trying to establish the information systems to perform intelligent warfare and innovate defense operations. The C4I(Command, Control, Communication, Computers and Intelligence for the Warrior) systems make it possible to do modern and systematic war operations. The basic idea of this study is to investigate how TAM(Technology Acceptance Model) can explain the acceptance behavior in military organizations. Because TAM is inadequate in explaining the acceptance processes forcomplex technologies and strict organizations, a revised research model based upon TAM was developed in order to assess the usage of the C4I system. The purpose of this study is to investigate factors affecting the usage of C4I in the Korean Army. The research model, based upon TAM, was extended through a belief construct such as self-efficacy as one of mediating variables. The self-efficacy has been used as a mediating variable for technology acceptance, and the variable was included in the research model. The external variables were selected on the basis of previous research. The external variables can be classified into following: 1) technological, 2) organizational, and 3) environmental factors on the basis of TOE(Technology-Organization-Environment) framework. The technological factor includes the information quality and the task-technology fitness. The organizational factor includes the influence of senior colleagues. The environmental factor includes the education/train data. The external variables are considered very important for explaining the behavior patterns of information technology or systems. A structured questionnaire was developed and administrated to those who were using the C4I system. Total 329 data were used for statistical data analyses. A confirmatory factor analysis and structured equation model were used as main statistical methods. Model fitness Indexes for measurement and structured models were verified before all 18 hypotheses were tested. This study shows that the perceived usefulness and the self-efficacy played their roles more than the perceived ease of use did in TAM. In military organizations, the perceived usefulness showed its mediating effects between external variables and dependent variable, but the perceived ease of use did not. These results imply that the perceived usefulness can explain the acceptance processes better than the perceived ease of use in the army. The self-efficacy was also used as one of the three mediating variables, and showed its mediating effects in explaining the acceptance processes. Such results also show that the self-efficacy can be selected as one possible belief construct in TAM. The perceived usefulness was influenced by such factors as senior colleagues, the information quality, and the task-technology fitness. The self-efficacy was affected by education/train and task-technology fitness. The actual usage of C4I was influenced not by the perceived ease of use but by the perceived usefulness and selfefficacy. This study suggests the followings: (1) An extended TAM can be applied to such strict organizations as the army; (2) Three mediation variables are included in the research model and tested at real situations; and (3) Several other implications are discussed.

  • The Critical Consciousness Scale (CCS) is a scale developed by Diemer and colleagues (2017) that can measure the capacity of the oppressed or marginalized people to critically analyze their social and political conditions, support societal equality, and take action to change the perceived inequities. In this study, we validated the CCS for Korea by adapting and localizing the scale and validating it among university students. Content validity was verified by having five individuals with master's and doctoral degrees in psychology evaluate the suitability of the translated items. Afterwards, reliability and validity were verified through a survey of 314 university students nationwide using the CCS, along with the opportunity inequality recognition scale, recognition of the need for environmental change scale, social participation scale, and belief in a just world scale. To verify the scale's validity, exploratory factor analysis was conducted, confirming three subfactors. Then, a confirmatory factor analysis was carried out, where 14 items out of the original 22 were retained. The construct validity and reliability of these 14 items were found to be satisfactory. Additionally, in the correlation analysis between the CCS and similar scales, a significant clear relationship was found. The CCS showed a positive correlation with scales such as opportunity inequality recognition, need for environmental change recognition, and social participation, and a negative correlation with the belief in a just world scale. Based on these results, the CCS can be considered valid and reliable. Finally, the limitations and significance of this study were discussed.

  • In this paper, I have attempted to show how the environmental controversy surrounding the Saemangeurn Reclamation Project in Korea has been framed as narrow scientific debates. First of all, science, or specifically the Expert Review Pane, has played dual roles in the controversy. On the one hand, it has contributed to illuminating the future environmental impacts of reclamation, by so doing, to providing a momentum to reconsider the project. This has significant meaning that environmental concerns successfully checked the symbolic national project of developmental era through adopting a joint-investigation scheme that guaranteed participation of environmental groups on an equal footing with the government. On the other hand, by limiting the scope and participants of discussion, it fundamentally blocked the possibilities of public debates and deliberative decision-making with full considerations of the political, social, and cultural aspects of the controversy. I have shown that this is due to the realist belief shared by both the developers and the environmentalists in Korea that 'proper' science would disclose the truth. Environmental groups, in particular, were naive in evaluating the role of scientific expertise in the controversy and neglected the political role of the Expert Review Pane as a ritual. In opposition to the realist argument, I have shown through the analysis of the water quality debates concerning the future fresh water lakes that scientific 'facts' were not discovered but constructed through complex negotiations, conflicts, and compromises among related actors. The framing of the controversy as an experts' debate has resulted in the exclusion of an important actor from the discussion. Little attention has been paid throughout the controversy to the very people who have lived in the Saemangeum area for generations and will lose their livelihood all together soon. About 20,000 fishermen are living on the Saemangeum tidal flats.

  • Environmental risk is one of major risks in contemporary society which is often conceptualized in terms of 'risk society'. The crisis which retains such environmental risk can be characterized by 'technical hazards', rather than natural hazards in traditional societies, because of potentiality of technical control over its generation and managing process. Environmental crisis tends to be recurred due to certain limitations of response of both government and civil society. Moreover, it can be argued that generation of environmental crisis and limitations of its managing process are inherent in problematic structures in contemporary society, especially in its 4 basic elements and their characters; that is, capitalist market economy which promotes increasing profits and decreasing cost; bureaucratic representative politics which has brought about concentration of power and evasion of responsibility, instrumental science and technology which leads to blind belief on scientific knowledge and its uncertainty; and finally individualistic way of life with exclusive and passive response to crisis. This paper aims to consider the generation and managing process of environmental crisis in terms of these 4 basic elements, with comparative studies on empirical cases of the water crisis by Phenol pollution in Taegu in 1991 and the water crisis by parasites contamination in Sydney in 1998.

  • Food adulteration and food fraud should not be neglected. The present study aimed to investigate the awareness of adulterated food and its management beliefs and capabilities among teenagers' parents. Data were collected from 425 adolescents' parents having different levels of income and education. The results of factor analysis indicated that adulterated food management beliefs was classified into attitude, necessity, and anxiety. The adulterated food management capability was sub-grouped into hygiene and nutrition, knowledge, citizen action and environmental grasp. The adulterated food management capabilities were significantly different according child's school, education level and monthly income (p<0.05). The attitude factor of adulterated food management beliefs appeared to have a significant (p<0.05) impact on all factors of adulterated food management capabilities, however the necessity factor had a significant (p<0.001) impact only on factor of hygiene and nutrition. The results of the present study suggested that parents need to be aware themselves as well as to teach their children about right food selection and consumption. The findings of the study might be useful in government policy planning regarding the public health issues and dietary education of adolescents and parents.
