Our society has been dominated by the Dilemma Theory that rational individuals cannot get out of the 'Tragedy of the Commons' without helps from state or market. However, many empirical researches have discovered cases that common pool resources could be managed by cooperative methods of community. Based on the possibility of managing common pool resources by residents' cooperation/solidarity revealed by the recent case researches, this study aims to seek for the theoretical basis to prove it. Generally, public policies are carried forward based on the theoretical basis of the relevant social issues. The objective of this study is to suggest the new direction of policies related to domestic common resources through the researches on community's role in managing local common pool resources represented as "scenic spot". For this, it aims to reveal the influence of community activity on behavioral intention of local common pool resources, by drawing/quantitatively measuring measurement items of local residents' community activity on top of attitude, norms, and behavioral control suggested by the existing Theory of Planned Behavior. The results of this study are as follows; 4 factors such as attitude toward behavior, subjective norm, perceived behavior control, and community activity were all factors that influenced intention to manage.

Fractures of galvannealed coating layer during actual press forming in automotive applications were observed by scanning electron microscopy in order to understand fracture mechanism. Fracture behaviors of galvannealed coating layer in extra deep drawing quality steels and high strength steels have been studied by performing the tests describing the representative plastic deformation in sheet metal forming such as uni-axial tensile test, compression test, bi-axial test and plane strain test. Growth and direction of cracks were deeply related to the plastic deformation modes and history. The material properties of galvannealed coating layer were investigated by nano-indentation test equipped with Berkovich diamond indentor for the specimens. Hardness and elastic modulus of the coating layer were higher than bared steels and that was the reason for crack of coating layer. Flat friction test and drawbead friction test were performed to observe the effect of the surface morphology on the frictional characteristics. The micro-plasto hydrodynamic lubrication were appeared and played an important role in reducing the coefficient of friction.

Aiming at the phenomenon of false information issued by service providers in cloud computing environment, a method for service evaluation based on fuzzy theory is put forward in this paper. According to the quality of services provided by cloud service providers and their behavior during interactions, a trust relationship between cloud service providers and cloud service consumers is established, which can be quantified by using fuzzy theory. The quality of services is evaluated by drawing on the trust relationship. In our method, the recommendation credibility of a cloud service consumer is determined through behavior similarity with evaluators and a praise factor. The introduction of the praise factor better suits the phenomenon of a high-quality service getting more repeat customers. The negative impact of dishonest customers is reduced, and the accuracy of trust and cloud service quality evaluation is improved by introducing a confidence factor that can be dynamically adjusted. The experimental results show that our method can effectively and accurately evaluate the trust value and service quality of providers, while weakening the influence of dishonest consumers, and quickly detect dishonest service providers. This is beneficial for consumers trying to find high quality service providers for similar services.

Purpose - The purpose of our study is to provide an understanding of the relationships among consumer attention to social comparison information (ATSCI), consumer ethnocentrism (CET), national identity (NI), and consumer purchase intention to domestic brands (PIDB). Drawing on the social comparison theory (SCT) and social identity theory (SIT), we developed a model that is empirically testable and explains consumer behavior of domestic brands and products. Research design, data, and methodology - The conceptual framework was tested with primary data collected through a survey in China. Structural equation modeling was employed to test hypotheses. Results - The results from empirical analyses indicated that the ATSCI positively influenced CET and NI, and CET and NI affect consumer PIDB. In addition, the mediating effects of CET and NI on the relationship between ATSCI and PIDB were identified. Nonetheless, little direct impact of ATSCI on PIDB was reported. Conclusions - We suggested that international marketers use given information to attract consumer attention and develop appropriate promotions, especially for Chinese young generations that would pay much attention to social comparison information in their purchase decisions. Our study originally connected one socio-psychological antecedent, ATSCI, with CET and NI and estimated the relationships among the three antecedents and their effects on PIDB in order to predict consumer behavior in China.

The purpose of the present study was to test the behavior of dietary life, the preception of body image and the attitude of body weight control of the subjects, and to imagine difference of value evaluation about thirteen foods. the subjects were 570 high school students who were living in Seoul. The results can be summarized as follows: 1. In selecting actual and ideal body sizes from a series of five outline drawings of female figures that ranged form 20% underweight to 20% overweight, 64% of the subjects selected overweight drawing s as their actual sizes, and 85.1% of the subjects selected underweight ones as the ideal sizes. 59.3% of the subjects had a desire to lose weight, 20.8% to gain weight. Those who think they are thinner than standard body weight were more satisfied with their body sizes than those who think they are fatter than that. Most subjects (79.8%) were concerned about their weight control, and the majority of them (36.1%) began to take concerns about it in their high school days, through the conversation with their friends about their body sizes. 2. In this study, thirteen foods were chosen as samples; rice, bread, salad, milk, cola, cider, juice, duck-bok-ki, chocolate, batterfriend foods, chinese noodles, cookies, fruits. Most of them evaluated foods on the basis of the taste. They valued fruits over any other foods as least fattened food, while they thought of such foods as rice, cola, cider, ice-cream, chocolate, batter-fried food, chinese noodles as fattened foods.

Due to advances in information and communication technologies (ICTs) and the advent of the Smartphone, people have access to the internet and can work at any time and any where. These are however likely to cause negative effects such as the personal information leakage and invasion of privacy. Caused by negative aspects of ICTs, the stress is so-called technostress. Recently, it is reported that managers tend to task order to their subordinates using an SNS or mobile messenger on a real-time basis after office hours or even on holiday, leading to a sharp increase in technostress. While previous studies of stress indicate that it is associated with the counter-productive work behavior (CWB), no empirical evidence has shown about the relationship between technostress and CWB. This study aims to explore the effect of technostress on CWB. In addition, it seeks to clarify the moderating effect of leader-member exchange(LMX) in this relationship. Drawing on literature regarding technostress and CWB, hypotheses are developed and tested with the sample of 101 using regression analyses. Results show that technostress has a significantly positive effect on CWB, but LMX has an insignificant moderating effect in the relationship between technostress and CWB. Implications and limitations with suggestions for future studies are presented.

Purpose: The hospitality sector is vital to economic development, especially in metropolitan regions, where hotels are a pivotal factor in drawing in leisure and corporate visitors. Despite the potential advantages of urban hotels, there is a gap in empirical studies on the impacts of eco-friendly interior design on hotel appeal and guest behavior. Therefore, this study aims to fill out the research gap. Research design, data and methodology: This study employed a review of the literature systematically as its research design. The study's data collection technique involves exploring peer-reviewed journals through electronic databases like Scopus, and Web of Science. The present author double-checked the quality of instrument for all usable dataset. Results: Prior literature has stated a strong linkage between green interior design in urban hotels and customer behavior and hotel attractiveness. Using environmentally conscious methods, hotels can enhance the quality of their indoor atmosphere, preserve energy and water supplies, and establish a favorable public perception that appeals to environmentally aware consumers, thereby improving their overall experience and contentment. Conclusions: This study concludes that creating indoor spaces with environmental factors in mind could lead to a more enjoyable and beneficial atmosphere for hotel visitors and adopting a sustainability-oriented approach to hotel design and operations could attract potential customers.

This paper is concerned with spring back after sheet forming of bulk amorphous alloys in the super cooled liquid state. The temperature-dependence and strain-rate dependence of Newtonian/non-Newtonian viscosities as well as the stress overshoot/undershoot behavior of amorphous alloys are reflected in the thermo-mechanical Finite Element simulations. Hemispherical deep drawing operations are simulated for various forming conditions such as punch velocity, die corner radius, friction, blank holder force, clearance and initial forming temperature. Here, spring back by an instantaneous elastic unloading was followed by thermal deformation during cooling and two modes of spring backs are examined in detail. It could be concluded that the superior sheet formability of an amorphous alloy can be obtained by taking the proper forming conditions for loading/unloading.

Media company is not a business which sells news and information but a company sells audience's attention. Advertisers estimate audience's quantity and quality which pay attention to media and pay the cost. Thus drawing audience's attention is a natural and instinctive behavior for survival of media company. News doesn't deliver the fact just as it. That's impossible. News is a commodity made by processing and selection of the media company and journalist. On the process, judge of values is involved and limitation of time and place of media is considered. If scientists understand media's character truly, their misunderstanding about media company and journalist may be cleared up. In this society, media is not a being to ignore, particularly for big science like space science which spends huge public capital. Nowadays, space science meets the time to take the leap in Korea. However that can be crisis cause of uncertainty of science activity. When the crisis which no one desires happens, preparation needs for new opportunity. We can take the crisis as a chance. Understanding about media and public will be the first step for this preparation.
