  • Mixed-matrix membranes (MMMs), which are composed of a polymer matrix filled with high-performance fillers as a dispersed phase, have been intensively studied for gas separations for the past 30 years. It has been demonstrated that MMMs exhibit superior gas separation performance compared to polymer membranes and are more scalable than polycrystalline membranes. Despite their potential, the commercialization of MMMs has yet to be reported due to several challenging issues. One of the major challenges of MMMs is the non-ideal interface between the continuous polymer phase and dispersed phase, which can result in defect formation (i.e., interfacial voids, etc.). With respect, many MMM studies have focused on addressing the issues through scientific approaches. The engineering approaches for facile and effective large-scale fabrication of MMMs, however, have been relatively underestimated. In this review paper, a novel strategy for fabricating MMMs in a facile and scalable manner using in situ metal-organic framework (MOF) formation is introduced. This new MMM fabrication methodology can effectively address the issues facing current MMMs, likely facilitating the commercialization of MMMs.

  • In the earlier study, Park (2002) described the process of student' conceptual change as a successive refinement and articulation of their conceptual framework. In this study, the process of conceptual change for three university students were analyzed more in depth. As results, six types of conceptual change through successive refinement and articulation were observed: (1) original conception was elaborated in detail, (2) conception was differentiated according to the context, (3) some conceptions were re-explained theoretically after construction it based on experimental data, (4) non-coherent conceptions in the early stage get to have coherency in the later stage, (5) model of explanation gets to be complicated by excluding ideal conditions, (6) qualitative explanations were changed into quantitative ones.

  • The most critical problem of MIS evaluation is the lack of the systematic framework to cover various factors and viewpoints. To solve this problem, this study takes the multi-level and contingent approach to performance evaluation, composed of three levels: evaluating the contribution of MIS to an organization [strategy level]; evaluating the activities of MIS department or MIS function as an organizational sub-function through the overall MIS lifecycle [function level]; and evaluating the quality or productivity of the application systems as MIS outputs [system level]. Ideal MIS evaluation should include all three levels of the hierarchy with balanced importance. However, MIS evaluationcanbedividedintothreetypes,suchasstrategy-oriented, function-oriented and system-oriented evaluation, depending on the focus and emphasis of evaluation. The usage pattern of each evaluation type is analyzed according to contingent variables of MIS evaluation such as MIS maturity, information intensity and firm size, and top management's intent. It is also found that the firms of higher MIS maturity and top management's intent use the strategy-oriented evaluation type, and the firms with strategy-oriented evaluation type show a higher MIS performance. Further, MIS maturity and top management's intent show contingent effects between evaluation type and MIS performance. Some managerial implications can be drawn based on the results of the study. First, strategy-oriented evaluation of MIS is more important as many firms more often use information technology as a strategic weapon. Second, MIS performance varies with evaluation type. Therefore, the design of MIS evaluation framework should be done carefully in the strategic and managerial contexts. Third, firms are recommend to use a different evaluation type according to organizational characteristics such as MIS maturity and information intensity.

  • Clothes and human body are inseparably related. Aesthetic consciousness of the body determines the form of clothing, reflecting the time and culture as well as the individual and society. Clothes can even reorganize the meaning of the body, while transcending their instrumental functions of protecting, expanding and deforming the body. Using 'body' to analyze the clothing form, my study develops a framework by which to classify the planarization of the body in Japanese avant-garde fashion. In order to inquire the formative style and aesthetic values expressed in Japanese avant-garde fashion, my study examines subjects from the discourse on the body to the fashion collections of the 20th and 21st century. The results of the study are as follows. Japanese avant-garde fashion focuses on a planarization of the body which questions the three dimensional construction of the body in more conventional clothing system. Un-structured, variable space posited between the body and clothes, participation of the wearer, attention to recent technology and material, and absence of gender identification characterizes the planarization of the body in Japanese avant-garde fashion. The absence of body in fashion stresses a will-to-form rather than mere bodily proportion and structure, which explores trans-extensity that goes beyond the boundary of the body Ultimately, planarization of the body betrays the correspondence between signifiant and signifie in sartorial convention. Aesthetic ideal of the body is visualized in the form of a dress. Some clothes prioritize the body, particularly the feminine bodily curves, while others focus on the clothing itself as abstract and sculptural forms. Fashion continues to explore forms and images that transcend the traditional representations of the clothed body. As a type of intimate architecture, fashion always mediates the dialogue between clothes and body, or fashion and figure. My study suggests a framework to analyze bodily representation in Japanese avant-garde fashion, focusing on the relationship between the clothes and body.

  • Tobacco use is described as the single most preventable cause of morbidity and mortality globally, with the World Bank predicting over 450 million tobacco-related deaths in the next fifty years. In India, the proportion of all deaths that can be attributed to tobacco use is expected to rise from 1.4% in 1990 to 13.3% in 2020 of which smoking alone will cause about 930,000 adult deaths by 2010. Many studies have shown that counseling from a health professional is an effective method of helping patients quit the tobacco habit. Tobacco cessation needs to be urgently expanded by training health professionals in providing routine clinical interventions, increasing availability and subsidies of pharmacotherapy, developing wide-reaching strategies such as quitlines, and costeffective strategies, including group interventions. The WHO Framework Convention on Tobacco Control (FCTC) emphasizes the vital contribution of participation of health professional bodies, as well as training and healthcare institutions in tobacco control efforts. Dentists can play an important role in helping patients quit using tobacco. One of the key strategies to reduce tobacco-related morbidity and mortality is to encourage the involvement of health professionals in tobacco-use prevention and cessation counselling. The dental office is an ideal setting for tobacco cessation services since preventive treatment services, oral screening, and patient education have always been a large part of the dental practice.

Clothes can even reorganize the meaning of the body, while transcending their instrumental functions of protecting, expanding and deforming the body. Using 'body' to analyze the clothing form, my study develops a framework by which to classify transfiguration in fashion design. In order to inquire tile formative style and aesthetic values expressed in transfiguration in fashion, my study examines subjects from the discourse on the body to the fashion collections of the late 20th and 21st century. The results of the study are as follows. Transfiguration signifies absence of body which questions the three dimensional construction of the body in more conventional clothing system. Transfiguration is expressed in non-figural forms which implies metaphorical plasticity and abstract extensity. Transfiguration in fashion stresses a will-to-form rather than mere bodily proportion and structure, which explores trans-extensity that goes beyond the boundary of the body. Ultimately, this phase also betrays the correspondence between signifiant and $signifi\acute{e}$ in sartorial convention. Aesthetic ideal of the body is visualized in the form of a dress.

  • Traditional Hanok in modern society, depending on the improvement of economic and cultural level is evolving as a modern Hanok. An ideal of traditional Hanok and convenience of a modern housing does not match rather conflicting. This study deals the transformation of a new Hanok, which are build in Jeollanam-do province sponsored by local government from 2007. The subjects was selected 34 cases from Sunchon and Damyang which are build sponsored by Jeollanam-do local government from 2009 to 2011. The report is a design drawing of a Hanok, architectural survey of the Hanok research using questionnaires and interviews with the client or a resident, was confirmed by a visit to check and verify for each Hanok houses. Outside shape classification of Hanok were classified as straight, L type, and the interior space was analyzed by focusing on the living room, dining room, kitchen configuration consisting of housing space in public life. This study and the type of Hanok round out the framework from the perspective of residence' demands and realize new Hanok investigated and the evolution of the process is meaningful to find a Hanok.

  • The six fabliaux of the Canterbury Tales are a notable artistic achievement. Of all of them, however, the Merchant's Tale is the most notable to show Chaucer's development of the scope of this genre. We will look briefly at the characters of the fabliau narrators who are crucial to Chaucer's drama of relationships in the course of the Canterbury pilgrimage framework. To distinguish the accomplishment of the Merchant's Tale, we will consider the relative merits of each of the other five fabliaux in the Canterbury Tales. The least flawed of the fabliau narrators, the Merchant will tell a powerful tale about an old man's lust turned into a hasty marriage gone wrong that aims its satire at the noble ruling class of the land, not the usual targets of Chaucer's or most other writers' fabliaux. Further, unlike the light-hearted and dismissable endings of the other Chaucerian fabliaux, the Merchant's Tale has what we will call an Act 6 of continued deception at all corners of the love triangle represented by the senex amans January, his young wife May, perhaps now pregnant after her tryst with Damyan in the pear tree, and the still present young lover Damyan. This triangle of mutual deception will continue into the unknown future under the male and female forces at odds as personified in the king and queen of fairies, Pluto and Proserpina.

  • The purpose of this study is to provide a decision support to select an appropriate rapid prototyping(RP) machine that suits the application of a part. Selection factors include concept model, form/fit/functional model, pattern model for molding, material property, build time and part cost that greatly affect the performance of RP machines. However, the selection of a RP is not an easy decision because they are uncertain and vague. For this reason, the aim of this research is to propose hybrid multiple attribute decision making approaches to effectively evaluate RP machines. In addition, because subjective considerations are relevant to selection decision, a fuzzy logic approach is adopted. The proposed selection procedure consists of several steps. First, we identify RP machines that the users consider. After constructing the evaluation criteria, we calculate the weights of the criteria by applying the fuzzy Analytic Hierarchy Process(AHP) method. Finally, we construct the fuzzy Technique of Order Preference by Similarity to Ideal Solution(TOPSIS) method to achieve the ranking order of all machines providing the decision information for the selection of RP machines.

  • The aim of this study is twofold. First, this study aimed to explore how Korean university students' English learning motivation is related to their English listening proficiency and study time. Second, it attempted to interpret the English learning motivation linking the two different motivation theories: self-determination theory and L2 motivational self system. The constructs of the students' L2 learning motivation were investigated with the data obtained through the questionnaire from 122 sophomore students. A factor analysis was conducted to extract the major factors of motivation. As a result, 6 factors were extracted: Intrinsic Pleasure, Identified Value Regulation, Intrinsic Accomplishment, Introjected Regulation, External Regulation, and Identified Regulation. The Interrelatedness among the assessment results on the L2 listening proficiency (pre and post test), listening study time, and motivation factors was measured by correlation coefficients. The statistical results indicated that pre-test scores were significantly related to Identified Regulation and Identified Value Regulation toward English learning, and post-test results had significant correlation with Intrinsic Accomplishment and Identified Regulation. However, no motivation subtypes showed statistical association with the students' listening study time. The results were attempted to be interpreted both under L2 motivational self system and self-determination framework to better illuminate the motivation theory with more explanatory power.
