`Early adopters,` a term first used by Everett Rogers in 1957, refers to people who are among the first to try a new product and like to evaluate the product for others. Early adopters in the digital age of the 21st century, greatly influence others by exchanging information on products and writing product reviews on Internet boards. Technological products have recently been released in the fashion world to become important fashion items, and early adopters are active buyers of these products. The purpose of this study is to examine the values and characteristics of early adopters as consumers of technological fashion products, and present a standard for designing fashion products in the future. This study was based on documentary research, Internet research and in-depth interviews. Documentary research was carried out to examine the lifestyles, characteristics and consumption habits of early adopters. Internet research was done to understand the tendencies of Korean early adopters, and a total of 18 websites were studied in 7 product categories. The subjects of in-depth interviews were 6 people who were either webmasters or members of early adopter-related websites. IT field early adopters tended to pursue new technologies, and fashion early adopters placed importance on how well a person could express their own style. New, unique, useful and pretty were the key words to describe the tendencies of early adopters, and fashion early adopters preferred the latest contemporary styles. Interviewees placed most importance on price, design and function of products. Since IT related products are continuously being added on to clothes and becoming fashion products themselves, further research on technology-related fashion design would be significant.

Most of ferrous b.c.c weld materials have martensitic transformation during rapid cooling after welding. It is well known that volume expansion due to the phase transformation could influence on the relaxation of welding residual stress. To apply this effect practically, it is necessary to establish a numerical model which is able to estimate the effect of phase transformation on residual stress relaxation quantitatively. For this purpose, the analysis is carried out in two regions, i.e., heating and cooling, because the variation of material properties following a phase transformation in cooling is different in comparison with the case in heating, even at the same temperature. The variation of material properties following phase transformation is considered by the adjustment of specific heat and thermal expansion coefficient, and the distribution of residual stress in analysis is compared with that of experiment by previous study. In this study, simplified numerical procedures considering phase transformation, which based on a commercial finite element package was established through comparing with the experimental data of residual stress distribution by other researcher. To consider the phase transformation effect on residual stress relaxation, the transition of mechanical and thermal property such as thermal expansion coefficient and specific heat capacity was found by try and error method in this analysis. In addition to, since the transformation temperature changes by the kind and control of alloying elements, the steel with many kinds of transformation temperature were selected and the effect of transformation on stress releasement was investigated by the numerical procedures considering phase transformation.

The aim of this study is to determine whether the 65 competencies, defined in "the role of Korean doctor, 2014", are suitable for basic medical education phase in Korea. It seeks to analyze the gap among the educational reality and expectation, assessment situation of the competencies above. We also try to define issues of the development, application and assessment phases of competency-based medical education (CBME) at individual medical schools. We designed survey tools based on the Miller's assessment pyramid (knowledge, explanation, demonstration, and performance) for each of the 65 competencies. The survey distributed to 41 medical schools in April 2015 and 38 replies were received (92.7%). Competencies that matched both the educational reality and expectation were numbers 1 (patient care), 33 (social accountability), and 49 (professionalism). However, all the other competencies ranked lower in current status than that of desirable level. 54 out of 65 competencies (83.07%) remained at the knowledge and explanation level when each competence were assessed. In the development, application, and assessment phases of CBME, common issues that medical schools commonly noted were difficulty linking competencies to curriculum preparation and student assessment, the lack of faculty's understanding, difficulty to reach consensus among faculties, and absence of teaching and learning methods and assessment tools that fits CBME. For the successful settle down of CBME, there is a need for efforts to develop the model of graduate outcomes, to share information and experience, and to operate faculty development program by the medical education communities.

Thanks to both developments in various media such as the internet and TV and China's economic growth, the fashion market in China has gain a lot of attention by global businesses as a newly-raised spending market. Fashion companies in Korea have entered into the china since the late 1990s. For them to get competitive edges, they have to differentiate their brand by creating new design based on the culture becoming mega-trend in fashion market. So in this research, I try to create fashion designs based on Hallyu Stars' fashion styles and images, who come on as a new culture code in China and other Asian. For this, I conducted theological consideration on what the Hallyu is, and looked into fashion styles in soft dramas which 5 Hallyu Stars started in and street fashion in Shanghai in China. Based on the outcomes of analysis, I figured out those star's fashion style and created products targeting young generation born after 1980s in China. The conclusion of this study is as follows. Firstly, the very definition of Hallyu which can be described as a phenomenon in which Korean movies, soap operas, and pop music have become immensely popular throughout Asia.has been expanding to signify the proliferation of Korean culture as a whole. Secondly, having selected the 5 female stars representing Hallyu, we were able to analyze and categorize their fashion styles on the basis of their music videos, movies, and soap-operas. Thirdly, In order to explore the level of influence of Hallyu fashion industry, we studied the street fashion of Shanghai The result was that we could observe both the slim and feminine cool casual style and the cute and affectionate pretty casual style simultaneously.

In this study we try to design and develop a mixed model of project-based learning with internet. In order to support the developed model, we separately developed a web-based tool, called Project Learning BBS. The classroom teaching for advertisement-photo production with the model has been carried out during May-July in 2002 and March-July in 2003 respectively with 40 students each. The overall activities of group collaborative work done during the teaching periods have been formatively evaluated with classroom observation, interviews and students' portfolios that were related to the processes of photo planning, video shooting and editing. It has also investigated how the students involved the web-based group discussion activities. In short, data analysis indicated that the participants accepted the proposed project-based learning model for their learning events in a positive way in order to increase the utilization of CMC.

In plants, cysteine(Cys) is decisive for protein and glutathione that acts as an indispensable sulfur grantor for methionine and many other sulfur containing secondary products. Cys formation is involved in the consecutive two reactions using two enzymes-serine acetyl transferase (SAT) and O-acetylserine (thiol)lyase (OASTL) and appeared in plant cytosol, chloroplast and mitochondria. OASTL is able to produce mimosine with 3-hydroxy-4-pyridone (3H4P) in lieu of $H_2S$ for Cys. In this report, we describe the first time cloning, purification and characterization of cytosolic(cy)OASTL from M. pudica and its expression in Escherichia coli and try to find out the cross link between this OASTL and the mimosine formation and to elucidate the metabolic role of cy-OASTL in M. pudica. The purified recombinant protein was 34.7 KDa. The optimum reaction pH and temperature was 6.5 and $50^{\circ}C$, respectively. The Michaelis constant (Km) and the Vmax value of the enzyme was $252{\pm}25{\mu}M$ and $57{\pm}3{\mu}M\;cysteine\;min^{-1}\;{\mu}g\;protein^{-1}$ for sulfide and $159{\pm}21{\mu}M$ and $58{\pm}2.4{\mu}M\;cysteine\;min^{-1}\;{\mu}g\;protein^{-1}$ for OAS subsequently. After cleaving the His-tag, we tried to observe cy-OASTL to form mimosine with appropriate substrate but it was not successful. It may be concluded that cy-OASTL of the present study is only Cys specific, not mimosine.

Recently, human embryonic stem cell research raises exciting public expectation on medical possibilities as well as ethical debate. Embryo management has become an integral part of the management of infertility treatment, researches on embryo and human embryonic stem cells and so on. Britain has permitted the research on stem cells derived from human embryo which made the first nation to allow the cloning of human embryo for the stem cell research. However, new technologies such as the assisted reproductive technologies and human embryonic stem cell research continue to pose an increasing source of ethical dilemmas for physician, scientists, legislators, religious authorities and the general publics to deal with. None the less, the United Kingdom has adopted the most liberal policies regarding human embryo and human embryonic stem cell research. The implication of the British embryo management system are as follows: 1) the development of reproductive technologies and new stem cell research technologies continue to pose legal and ethical debates, since those involve several parties; 2) the UK has taken the legal and institutional approaches to cope with those serious issues; 3) the UK adopted most liberal policies regarding embryonic and human embryonic stem cell researches; 4) the British HFE Act is consistent with the existing Acts related to human embryo management and researches; 5) through amending the HFE Act to accomodate the changes of technologies, the UK try to minimize the legal and ethical burden on undertaking research regarding embryo. The debates about the researches on human embryo and human embryonic stem cells is likely to continue in the Korean society. Because of the controversy and competing ethical values, as well as the evolving technologies, so far no consensus exists in our society. It suggest that it is premature to bring closure by ruling out any particular approaches. Thus our society needs to make an efforts to find a basis which could resolve the societal controversies through enriching the societal conversation about the profound ethical issues regarding embryo management.

There are two targets to schedule parallel jobs in the Cloud: (1) scheduling the jobs as many as possible, and (2) reducing the average execution time of the jobs. Most of previous work mainly focuses on the computing speed of resources without considering other attributes, such as bandwidth, memory and so on. Especially, past work does not consider the supply-demand condition from those attributes. Resources have different attributes, considering those attributes together makes the scheduling problem more difficult. This is the problem that we try to solve in this paper. First of all, we propose a new parallel job scheduling method based on a classification method of resources from different attributes, and then a scheduling method-CPLMT (Cloud parallel scheduling based on the lists of multiple attributes) is proposed for the parallel tasks. The classification method categories resources into different kinds according to the number of resources that satisfy the job from different attributes of the resource, such as the speed of the resource, memory and so on. Different kinds have different priorities in the scheduling. For the job that belongs to the same kinds, we propose CPLMT to schedule those jobs. Comparisons between our method, FIFO (First in first out), ASJS (Adaptive Scoring Job Scheduling), Fair and CMMS (Cloud-Minmin) are executed under different environments. The simulation results show that our proposed CPLMT not only reduces the number of unfinished jobs, but also reduces the average execution time.

Today, a definition of tourism is shifting from simple sightseeing to experiencing various cultures directly and/or indirectly. Along with the shift, all countries of the world dedicate their full attention on globalization project. In order to do so, they try to promote their images and cultures through eating and drinking spaces for food where the rest of the world can approach with ease. China is a country of diverse culinary culture. By analyzing eating and drinking spaces operated in four Chinese cities, this research studies how the traditional Chinese elements are expressed in modernization. With the research, it will navigate a direction as a new design way to establish modernized traditionality in the future. The research conducted an advanced research that set up and analyzed a standard frame of realizing practice for traditionality. By doing so, it sorted out and reviewed the characteristics of interior space into four styles; an indicative imitation method, a partial invoked method, a partial transformation method and a conceptual reception method. According to the outcome of an analysis, (a) the indicative imitation method that directly employed Chinese tradition was most used one, followed by (b) the partial invoked method that carried a part of traditional space, (c) the partial transformation method that simplified or transformed the tradition, and (d) the conceptual reception method that interpreted hidden minds and concepts by illustrating modern spirit over an inherent order in traditional Chinese space, in respective order.

This paper deals with human spatial cognition using visual and auditory stimulation. More specially, this investigation is to observe the relationship between the head and the eye motor system for the localization of visual target direction in space and to try to describe what is the role of right-side versus left-side pinna. In the experiment of visual stimulation, nineteen red LEDs (Luminescent Diodes, Brightness: $210\;cd/^2$) arrayed in the horizontal plane of the surrounding panel are used. Here the LEDs are located 10 degrees apart from each other. Physiological parameters such as EOG (Electro-Oculography), head movement, and their synergic control are measured by BIOPAC system and 3SPACE FASTRAK. In the experiment of auditory stimulation, one side of the pinna function was distorted intentionally by inserting a short tube in the ear canal. The localization error caused by right and left side pinna distortion was investigated as well. Since a laser pointer showed much less error (0.5%) in localizing target position than FASTRAK (30%) that has been generally used, a laser pointer was used for the pointing task. It was found that harmonic components were not essential for auditory target localization. However, non-harmonic nearby frequency components was found to be more important in localizing the target direction of sound. We have found that the right pinna carries out one of the most important functions in localizing target direction and pure tone with only one frequency component is confusing to be localized. It was also found that the latency time is shorter in self moved tracking (SMT) than eye alone tracking (EAT) and eye hand tracking (EHT). These results can be used in further study on the characterization of human spatial cognition.
