Among many other alternative energy resources, small scale hydropower has been brought into attention as a reliable source of energy today, which had been relatively neglected since 1960s. Present low head of Francis turbines and small scale hydroturbines, however, have limitations in the minimum required head and flow rate for efficient operation. This study attempts to develope the Francis turbine which is expected to run efficiently even in very low head and small flow rate, so that the limitations on the conventional small scale hydropower could alleviated and competition with other alternative energy sources in the changable design conditions could attained. The Francis turbine of a new concept was designed based on changable design conditions, hydrodynamics and theory of power transmission. The result of the study shows that two stages runner is more efficient, cheaper in construction, faster responding, and easier maintaining than single stage runner of Francis turbine

The concept of office will change from the physical workplace with paperwork to unphysical workplace with paperless-work in the information-oriented society of the 21th century. We can find such change from increasing of alternative office, e.g. SOHO(Small office home office), Virtual office, Electronic office, Digital workplace, Satellite office, Hotelling, Telecommuting, etc. In this paper, through a few cases in the advanced nations you shall probably get answers to following questions: How do they make use of alternative office, what is strategic values of that, and how shall we design and build it to increased business performances in the business world?

Purpose: The purpose of this study was to develop a fundamental reference for the clinical implementation of Complementary and Alternative Therapy(CAT) by surveying and analyzing different perception and attitude between nurses and physicians. Method: A total of 167 nurses and 103 physicians from two C university health science centers participated in this survey, and SPSS program with version 10.0 was used to analyze the result of survey. Result: As results, 72.7% nurses and 57.1% physicians showed positive attitude for the concept of CAT, 60.6% nurses and 36.7% physicians responded positively while 2.6% nurses and 25.9% physicians responded negatively for the application of CAT to the clinical practice. There was a meaningful difference between two groups in the belief of therapeutic effectiveness of CAT. 67.7% nurses believed the therapeutic effectiveness of CAT while 38.8% physicians did. For attitudes of nurses and physicians toward CAT showed meaningful difference according to general characteristics: age, gender, marital status, a level of education, position in the organization, religion, and duration of health care service other than inpatient units. Conclusion: In this study, the attitudes of nurses and physicians about CAT showed meaningful difference that nurses were more positive than physicians in application.

Unsatisfied with the modern medicine's treatment of diabetes, patients diagnosed with the disease turn to alternative medicine for treatment. A look at the percentage of people using alternative medicine marked 72.8% in the United States and more than 60% in Korea in 2006. The most preferred form of alternative medicine turned out to be usage of dietary supplements and herbal medicine. Most of the dietary supplements and herbs that diabetic patients use largely originated from their usage in East Asian Traditional Medicine. As Western Medicine made its way into East Asia in late 18th century, excessive efforts were made to translate Western medical terminology into traditional medical terminology equivalents. In the process of doing so, wasting-thirst became a concept equivalent to diabetes. Theories regarding the pathogenic outbreak and transmission of wasting-thirst has been supplemented and progressed according to needs and even showed new tendencies. Profound understanding of wasting-thirst achieved through historical research is expected to lead to proper application of wasting-thirst treatment methods in treating modern diabetes.

My aim in this paper is to provide a clear view of Victorian gender ideology and highlight the role played by Browning's dramatic monologues in the challenge against the strict patriarchal codes of the era. Laura Mulvey's Male Gaze theory in cinema is especially useful for understanding Browning's most well-known dramatic monologues, "Porphyria's Lover," and "My Last Duchess," because these poems are structured by polarities of looking and being looked at, the active and the passive. In her 1975 essay "Visual Pleasure and Narrative Cinema", Mulvey introduced the second-wave feminist concept of "male gaze" as a feature of gender power asymmetry in film. To gaze implies more than to look at – it signifies a psychological relationship of power, in which the gazer is superior to the object of the gaze. She declares that in patriarchal society pleasure in looking has been split between active/male and passive/female. Browning's women are subject to the male gaze, but they refuse to become the objects of a scopophilic pleasure-in-looking. Porphyria and the Duchess don't exist in order to satisfy the desires and pleasures of men. They reveal themselves as an autonomous being - reserved in Victorian gender dynamics for men. Mulvey advocates 'an alternative cinema' which can challenges the male-dominated Hollywood ideology. It is possible to say that Browning's dramatic monologues correspond to Mulvey's 'alternative cinema' because they show a counterview in terms of the representation of woman against the Victorian patriarchal ideology.

This research introduced the concept of 'alternative attractiveness' derived from the social exchange theory to the research model predicting turnover intention among salesforce. By doing so, we tried to broaden the understandings of relationship between salesperson job attitude and salesperson behavior. We collected and analysed the data from the survey on the 178 salespeople employed at the life insurance companies. We found the alternative attractiveness to be a significant antecedent of the turnover intention. Specifically, the more attractive the alternative the greater the intention of turnover. However, we also found that the salesforces are less attracted to the alternative if they are more satisfied with their jobs. Finally, this research can be a seminary work with the relational perspective for the studies of salesforce management.

The Purpose of this study is to classify existing hysteresis models and to discuss a possibility of a new type of the hysteresis model. The existing hysteresis models are classified into three types: the interpolation model, the scaling model and the domain model, of which only domain model is to simulate hysteresis curves based on the theoretical approach, It is useful to develop a hysteresis model that requires only one branch of hysteresis curves for the model calibration because obtaining hysteresis curves by experiments is expensive and time-concept by many investigators, however their models are not successful to accurately simulate real data of Rubicon Sandy Loam and Dune Sand. There is a possibility that a new model is based on the dependent domain concept considering the weighting factor, $P_a$($\theta$), which accounts for the pore blockage effect against air entry. Conclusively, a new model where the weighting factor $P_a$($\theta$) in Model III-1 (Mualem, 1984) reduces to a known variable through an appropriate method is an alternative model which required only one branch of main curves for the model calibration.

Real-Time Enterprise concept comes out as an alternative to reduce the increasing uncertainty of the business environment recently. And lots of companies want to get Real-Time concept into their organizations. However, studies on RTE are not sufficient yet, from defining to realizing it. Thus, this study defines RTE activities with the RTE definition of Gartner and derives RTE critical success factors. During this study, system thinking is used to make interactions of RTE variables clear, and causal maps, generated by system thinking, are applied to derive CSF.

The purpose of this study is to determine the unidimensionality of Grasmick's operationalization of Gottfredson and Hirschi's criminality inducing the concept of low self-control. By applying confirmatory factor analysis procedures that incorporate advances in the application, the proposed six factor model and two alternative models were examined suggesting that Grasmick's low self-control scale actually contains 6 distinguishable factors, not a single factor. The factors identified to be consistent with the six-factor model were impulsivity, simple tasks, risk seeking, physical activities, self-centered, and temper.

Rapid prototyping for welding and milling is a hybrid approach that makes use of welding as additive and conventional milling as subtractive technique. For two years this concept has been used to verify manufacturing mold and mechanical parts successfully. In latest new fabrication methods. For example, manufacturing mold for two sort of materials and shell fabrication, have been applied to the concept in KIST. This methods will be an alternative proposal in rapid prototyping. Metal deposition for welding causes the part to deform. It is a handicap in our proceeding. To overcome this problem, in this paper, we represent an optimal welding path for FEM analysis. Eight paths are tried to this and the value of deformation is average and standard deviation in four points'. Then we can compare with eight cases and select the optimal path.
