Background: With global changes in the current state of work and employment, the role of health-adverse psychosocial work environments has received increasing attention in developed as well as in rapidly developing countries. Thus, there is a need to apply valid measurement tools for monitoring and preventive purposes. This study aims to examine the factorial structure and psychometric properties of the Persian version of the effort-reward imbalance (ERI) questionnaire, assessing one of the internationally leading concepts of stressful work. Methods: This descriptive cross-sectional study of a random sample of 202 white collar employees in an industrial company in Iran analyzes the ERI scales by exploratory and confirmatory factor analysis. Moreover, aspects of construct and criterion validity are tested. To this end, correlations of ERI scales with subscales of organizational injustice, a complementary work stress model, and also the correlations of ERI scales with a questionnaire assessing psychosomatic symptoms are performed. Results: Internal consistency of the three ERI scales was satisfactoryy (Cronbach ${\alpha}$ effort: 0.76, reward: 0.79, overcommitment: 0.75). Fit indices of confirmatory factor analsis pointed to an adequate representation of the theoretical construct (e.g., adjusted goodness of fit index (AGFI): 0.73, goodness of fit index (GFI): 0.78). Negative correlations with subscales of organizational injustice supported the notion of construct validity of the ERI scales, and positive correlations of ERI scales with psychosomatic symptoms indicated preliminary criterion validity. Conclusion: The Persian version of the ERI questionnaire has acceptable psychometric properties and can be used as a valid instrument in research on this topic.

"Bioethics" may have various meanings depending on its roles. It may mean professional ethics for scientists and physicians, etc. It may also mean an academic discipline using interdisciplinary approach as well as a philosophical or a legal approach. "Bioethics" as an interdisciplinary study should often deal with public policy on bioethical issues. I call this role bioethics as a study of bioethics policy, which has to be developed as a new discipline. From this perspective, I deal with bioethical issues relevant to a human life before birth. There are various and often conflicting arguments about the moral status of a human life before birth such as the fertilization argument, the argument of genetic identity, so-called the "14 days" argument focusing on the formation of primitive streak, the argument of sentient being, and Michael Sandle's argument of an embryo as a being between a thing and a person. I argue that each of them is reasonable. Thus we are faced with reasonable disagreement on the views over whether a human life before birth has the same right to life as that of a person or whether right to life may be considered to be a matter of degree. If we acknowledge reasonable disagreement, as John Rawls pointed out, we should tolerate the views from ours in a plural society. Therefore, we cannot help making a policy that allows abortion and embryonic research with some limitations. When we say a certain act is morally permissible, "moral permissibility" does not mean that the act is morally right for all. Rather it means that the act cannot help being morally allowed for some persons although the others do not believe its moral rightness because they cannot right now rationally persuade others to accept their view.

In order to correctly understand the Internet fashion shopping mall, which is expected to continuously grow up, and to strengthen marketing activities in cyber space, a more scientific and systematic research is necessary. Most of the early researches of the Internet fashion shopping mall were focused on technical parts so they studied the environmental and physical characteristics of the Internet fashion shopping mall, but recently, the Internet fashion shopping mall is activated and accordingly, the interest in Internet shopping users is going up. Under this circumstance, the research to understand the characteristics of Internet shopping consumers becomes necessary. Therefore, the research was conducted by a survey, focusing on college students who use Internet a lot. The survey covered the experience and the type of using the Internet fashion shopping mall, the extent of satisfaction, strengths, and weaknesses of the Internet fashion shopping mall, the use of a cyber fitting system, and the possibility of the development of the Internet fashion shopping mall having a cyber fitting system. As a result of the study, it was found that: most of the students used the Internet fashion shopping mall; they used a fashion-specialized mall most; they pointed out economy of time as the biggest strength of using the Internet fashion shopping mall; they thought the biggest weakness of the Internet fashion shopping mall is that they can not try on clothes so they can not check whether clothes go well with them or not; and regarding the intention to use a cyber fitting system if available and the possibility of the development of the Internet fashion shopping mall, they replied that they would use it and the malls with the system would be developed. Based on the results, this study proposes a cyber fitting system as an improvement of the Internet fashion shopping mall.

Until now, the 'Ie' system, the distinct Japanese Family system, was dominantly recognized as the vestige of former feudal system. But as the research for gender-especially the family history-gets active, various aspects showing that 'Ie' is the modern product developed through thoroughly intended plans of Meiji government after latter-day. According to Ueno Chizuko, 'Ie' system is not at all a traditional feudal system, but it rather is the family revised by modernization, in other word, it is the Japanese version of modern family. This words began with it being the study of goodwill, and recognizing that 'Ie' is the creation of modernization, and as well as the need to listen to the new woman's inner voice under the Japanese patriarchal system. The most appealing characteristic of modern Japanese patriarchal system is that the it needs only the family members who are dedicated to the 'Nation'. With this, women were expected to submit to the authority and their roles, which are, as a wife and mother who obeys by supporting, preserving, and maintaining the patriarchal system. But as the new women themselves expressed their independence, these roles are hard to be expected. It was no other than new women's magazine Seito which arose against the Japanese patriarchal system. In this statement, careful observation was done on the novel based on tiny internal conflicts or the aspects of anguish, that could not have been illustrated enough after judging the significant issues of early modern liberalism of women based on new women's editorials, discussions, that were illustrated most directly and compressively. Through this, it was pointed out that Seito magazine is not consisted logically, and that reason for that is the female authors' different desires were tangled and it reflects the complicated situation of that period whether they were intended or not. Overall, unlike the literatures (men-centered) of same era, the genre of literature or the novel did not put them on prerogative place, and confirmation could be made once again that the women's writing aspects are related closely with gender recognition more than anything.

Rapid development in the upper reaches of the Mekong River, in the form of construction of large hydropower dams and reservoirs, large irrigation schemes, and rapid urban development, is putting water resources under stress. Many scientific reports have pointed out that cascade dams along the Mekong River lead to serious problems: not only hydrologically but also a decline of agricultural productivity due to a decrease of sediment supply in the Mekong Delta and a change of fish amount due to drastic change of the water environment. Cambodia and Vietnam, located in the lowest Mekong basin, are gravely affected by radical changes of hydrologic regime due to Mekong River developments. In particular, the Tonle Sap Lake in Cambodia is very sensitive to the flood cycle and flow variation of the Mekong River as well as inflow water quality from the Mekong River. More than 50% of Cambodian GDP depends on the primary industries such as agriculture, fishing, and forestry, and the Tonle Sap Lake plays an important role to support the national economy in Cambodia. In addition, Cambodian people usually take nourishment from the fish of Tonle Sap Lake. This research aims to assess the impacts of the Mekong river flow alternation on the hydrologic regime of the Mekong River - Tonle Sap Lake. We carried out rainfall-runoff-inundation simulation using CAESER-LISFLOOD for integrated water resource management in the Tonle Sap Basin and then analyze flood inundation variation of the Tonle Sap Lake due to the scenarios. Furthermore, the simulated inundation maps were compared to MODIS satellite images for model verification and hydrologic prediction.

As carbon fiber reinforced composites(CFRP) are widely used in aerospace, automobile, marine, and sports goods applications, they have been studied extensively by various researchers. However, CFRP have been pointed out because of machining problems such as delamination and burr phenomenons. Especially, hole machining process, drilling, has non-smooth features on inlet and outlet surfaces of drilled hole. This kind of machining problem can be controlled to some extent by using high modulus pitch-CF, which has considerable effects on fracture behavior of composite compared with only PAN CF composite. Therefore, PAN and pitch hybridized CF composites were prepared having high strength and modulus. The results demonstrate that the hybrid CFRP specimens with pitch CF offer the good potential to enhance modulus as well as strength properties. Dynamic mechanical, flexural, and impact properties were measured and analyzed. Morphological surface of the composites were also observed by IFS-28, canon after hole machining.

in the conclusion, appealing ways of expression regarding a wider and more variated range are to be tested and it is stressed the necessity of this to be shown to the general public through an ongoing constructive research on the originality of contents arising from the diversity of music genres And, concerning dance music, it is also pointed out the necessity of in-depth research on the rhythms that take into account the universal emotions of the general public to create diverse music that harmonizes with the dance and can be enjoyed by all. In the world of music, just a simplest attempt can bring about many changes. Depending on the identity of those who lead it, that change's appearance or shape may also be different. Moreover, changes arisen from testing simplified rhythms will let experts to create new music. K-Pop is to test, more than anything, diverse strategies and new changes to be selected by such a wide public. However, such changes ought not to degenerate into mere imitations and can neither become obsolete. The reason lies in the fact that the current efforts for the sake of diversification and creativity of K-Pop genre might well remain as the traditional elements of the K-pop of the future.

This paper brings up fallacy of material factors specified for the design of concrete members in the current Korean limit state design code for highway bridges, and proposes new material factors based on a robust optimization scheme to overcome the fallacy. It is shown that the current load factors in the code and the proposed material factors lead to a much higher reliability index than the target index. The load factors are adjusted to yield the target reliability index using the inverse reliability analysis. A reliability-based approach following the basic concept of Eurocode is formulated to determine material factors as well as load factors. The load-material factors obtained by the proposed reliability-based approach yield a lower reliability level than the target index. Drawbacks of the basic concept of Eurocode are discussed. It is pointed out that differences in the uncertainties between materials and members may cause the lower reliability index of concrete member than the target.

This paper introduces an algorithm that compensates for missing values after converting them into a format that can represent the probability for incomplete data including missing values in training data. In the previous method using this data conversion, incomplete data was processed by allocating missing values with an equal probability that missing variables can have. This method applied to many problems and obtained good results, but it was pointed out that there is a loss of information in that all information remaining in the missing variable is ignored and a new value is assigned. On the other hand, in the new proposed method, only complete information not including missing values is input into the well-known classification algorithm (C4.5), and the decision tree is constructed during learning. Then, the probability of the missing value is obtained from this decision tree and assigned as an estimated value of the missing variable. That is, some lost information is recovered using a lot of information that has not been lost from incomplete learning data.

The purpose of this study is to seek practical implementation of adult learner-targeted college. For this, it first of all pointed out expanding opportunities of adult learners to learn and limitation of current lifelong education system at higher education level as well as lifelong learning centered university project. Then it selected and examined 3 university cases abroad, such as Harvard university, the university of Chicago in US and Warwick university in UK in terms of their curriculum and operating method for adult learners. In addition to the literature and case studies, this study did interviews on 5 professors with major of lifelong education and 5 managerial experts of university to suggest practical operating approach of adult learner-targeted college, which is as following. University's philosophy should be geared to meet public responsibility, specialization and persistency of the system and proper measurement be followed such as various range of admission track, prior education courses, recognition of prior learning experience, major, teaching method, curriculum and extra adult learner tailored service including financial support. Based on the study result, practical implications were suggested.
