The relaxation response is a state of profound rest, creates physiological responses directly opposite to the stress response. The relaxation response can be used to counteract the harmful effects of stress. The relaxation response can be elicited by a number of techniques such as diaphragmatic breathing, meditation, progressive muscle relaxation, autogenic training, biofeedback, etc. These relaxation methods in any mental or physical conditions associated with distress and even in normal people have useful benefits for stress control and health enhancement. These relaxation techniques are but one part of a comprehensive stress management program, through regular and continuous practice appropriate for each person, they will make an effective role in stress management. In this review, author reviewed how to practically use meditation, progressive muscle relaxation and autogenic training, in more detail. In the treatment of various stress-related disease, especially in psychiatric disorders, the relaxation technique may be a useful complement to conventional treatment and serves as an intervention between stress and disease.

A researcher, who is a member of an academic society, is required to write a report on his or her research and present it at an academic workshop in order to have the contents of the research recognized by others. In order to do that, the researcher frequently has to look up the web pages of each workshop for information such as the submission deadline, paper information, announcements and news. On the other hand, the academic society mostly relies on e-mail or bulletin board to send information about itself to its members to inform its members about its latest news or developments. A system where the researcher can gain all the information required through just a single click and the academic society can provide its members with the necessary information through a simple step is required for the ease of both side. We will take a look at the domestic status of researches being done on such systems where the RSS standard has been applied and suggest a RSS-based dissemination model where the concept of personalization has been applied to satisfy the needs of the individual user.

This paper investigates how firms adjust wages, employment and hours in response to demand shifts. It focuses on rigidities and asymmetries in such adjustments. Major findings are as follows. First, wage adjustments are fairly small compared with worker adjustments. Second, wage adjustments are asymmetric with respect to sales growth: there is no responsiveness of wage growth when sales are declining, while adjustments are significantly positive when sales are rising. On the contrary, worker adjustments are symmetric with respect to demand shifts. Third, while workers are linearly adjusted to the sales growth, some nonlinearity is observed in the wage adjustment. Fourth, hours are generally nonresponsive to demand shocks. Finally, union firms cut wages rather than workers in the face of negative demand shocks.

To determine the effect of chain length of linear amine curing agents on the thermal and mechanical properties, standard epoxy resin, diglycidyl ether of bisphenol A (DGEBA) was cured with diethylenetriamine (DETA), triethylenetetraamine (TETA) and tetraethylenepentaamine (TEPA) in a stoichiometrically equivalent ratio. From this work, the effect of linear amine curing agents on the thermal and mechanical properties was significantly influenced by chain length of curing agents. In contrast, the results showed that the DGEBA/DETA system had higher values than the DGEBA/TETA and DGEBA/TEPA system in the density, shrinkage (%), thermal expansion coefficient, tensile modulus, and flexural strength. Whereas the DGEBA/DETA cure system had lower values than the DGEBA/TETA and DGEBA/TEPA cure system in the maximum exothermic temperature, conversion (%), and T$_{g}$. These findings imply that the differences in the maximum conversion about the chain length of curing agents affect the thermal and mechanical properties.s.

수자원과 관련된 많은 분쟁 및 갈등들은 국내뿐만 아니라 전 세계적으로 발생하고 있다. 따라서 분쟁 및 갈등해결을 위한 많은 연구들이 진행되고 있지만 수자원과 관련된 분쟁들은 대부분 원활한 해결을 이루지 못하고 있으며, 특히 국내의 경우에는 더욱 심각하다 할 수 있다. 따라서 제한된 자원인 수자원을 둘러싸고 수자원분쟁이 일어나는 것은 당연한 일이라 할 수 있으며, 분쟁의 양상도 다양하다. 댐 건설로 인한 상류지역과 하류지역의 갈등, 수로의 건설로 인해 수자원을 빼앗기는 지역과 수자원을 얻게 되는 지역 간의 갈등, 새로운 공단이나 개발로 인하여 하류지역에서 수질악화를 우려하여 반대하는 경우 등 여러 종류의 수자원으로 인한 분쟁이 있다. 수자원을 둘러싼 갈등이 쉽게 해결이 되지 않고, 또한 갈등 및 분쟁이 쉽게 발생되는 이유도 주체자들간 입장 차이에서 오는 성격이라 할 수 있겠다. 수자원과 관련된 분쟁에서 오는 여러 가지 갈등들은 사회적으로 많은 문제들을 발생시켜 수자원의 원활한 공급이 저해될 수 있다. 이로 인해 사회적으로 수자원과 관련된 분쟁 해결에 들어가는 많은 시간과 노력, 비용을 생각해 볼 때, 효과적인 갈등 및 분쟁의 해결은 국가적 발전에 있어서 영향을 줄 수 있다. 그러므로 갈등 및 분쟁의 원활한 해결이 국가적 발전에 많은 비중을 차지 한다고 할 수 있다는 것은 이런 이유들 때문이라 할 수 있다. 본 연구에서는 국내 수자원과 관련된 분쟁사례들을 하천의 기능에 따른 분류, 발생 원인에 따른 분류, 분쟁주체에 따른 분류 등을 유형별로 구분하여 수자원분쟁의 여러 가지 사례들을 조사하였다. 또한 분쟁 및 갈등을 해결하기 위한 방안으로 거버넌스 시스템을 적용하였고 분쟁의 원활한 합의 조정방안 및 문제점을 제시하기 위한 외국의 시민참여 모델을 특징 및 특성을 분석하였다. 또한, 공영시각모형, 게임이론, 제도설계이론의 공학적 모형을 바탕으로 물분쟁의 해결을 위한 대안을 모색할 수 있는 과학적 접근 방안을 제시하여 향후 여러 가지형태의 국책사업 시행 시 발생 할 수 있는 분쟁의 해결 및 조정을 위한 방안으로 활용할 수 있는 토대를 마련하고자 한다.

The dependence of the etch rates of differently doped poly-Si films on the gas composition, the chamber pressure and the RF power was investigated in detail. The highest anisotropy and the lowest CD loss were achieved at the $SF_6$-rich compositions, i.e., $Cl_2:SF_6$=17:33 (SCCM), in the $POCl_3$-doped poly-Si. The etch rates increased for n-type dopant (phosphorus), while decreased for p-type (boron) with increasing the doping levels irrespective of plasma parameters. And from the results of the activation of doped poly-Si films the active carrier concentrations as well as the doping concentrations were found to be responsible for the increase of the etch rate of the phosphorus-doped poly-Si.

The purpose of this paper is to disclose the characteristics of SNS service platform in the perspective of 'dispositif'. To achieve this I extended Foucault's concept of 'dispositif' to the Internet and service platform of Google, Facebook. The platform dispositif is a complex of the interface services for the users, collection of data produced by users and the control of them. These three aspects are combined in the service platform modifying their modes in terms of time and space. This study would provide a critical approach toward the appropriation and control of user activities based upon platform.

The film has far-reaching power than any other media. For this reason, a censorship has existed in some way but censorship is like a double-edged sword. If KMRB stood in front of a desire to preserve the morals of society and youth protection, creativity of artists must be shaken. On the contrary if free will is emphasized, social chaos will be increase. Thus most countries made various censorship systems in order to overcome this contradiction. In recent years, mainly on the issue of censorship and the rating is a tendency to transfer to the voluntary deliberation agency. However, this issue is still dealing with this problem at KMRB in Korea. Then KMRB mistakes itself as the guardian of situation ethics and morality. Recently various problems appeared in the film rating system. KMRB should be devolved on the voluntary deliberation agency in order to solve the problem. therefore this study The study will be to review the need for voluntary veliberation agency.

The objective of this research is to investigate how consumers react differently to financial and social risk/return, referred to as an 'asymmetric effect'. A lab-based experiment using a counterfeit but real-branded product examined the robustness of the statement that priming the interdependent versus independent self can result in differences in financial and social risk taking behavior in the context of counterfeit product purchase choice. Three hundred fifty-eight participants took part in the experiment. They were primed with different self-construal and evaluated purchase intention to the counterfeit product. As predicted, when evaluate in the context of loss claim of counterfeit product, risks were more activated, however, there was an asymmetric effect that self-construal priming had on financial and social risks. Interdependence primed participants were more likely to take a financial risk thus perform more purchase intention of counterfeit product and less likely to take a social risk than their independence primed counterparts, which led to lower purchase intention. The results of this research shed light on the various directions of future studies on the responses toward counterfeit product.
