Cost of construction project have to be estimated based on drawing before execution. Cost estimate and check would be performed numerously for preparing general outline of requirements and determining the budget at conceptual planning stage, for obtaining decision on every matter related to design, specification, construction and cost at design stage, and for predicting bidding cost. Thus, importance of cost estimation cannot emphasize too much in construction. However, there are lack of standard estimation method, process, and cost analysis method, that square foot estimation method is as used as eyer, in Korea. Thus, This research present the direction for improving cost estimation and management in construction; It is demanded that establishing standard data base methodology, multi-level database model CUBE, and standard cost planning process, choosing cost estimation methodology according to objectives and cost planning process, and making more experts.

Essential tremor is a neurological disorder with a tremor of the arms and hands. It is well known that essential tremor is characterized by the postural tremor and the action tremor. There has been no report on the quantitative difference in the characteristics of two tremor types. The purpose of this study was to investigate the possible difference in tremor characteristics of postural and action tremors. Seventeen patients with essential tremor ($68.9{\pm}7.9years$, 7 men, 10 women) participated in this study. Patients performed the tasks of postural maintenance (arms outstretched) and daily actions (spiral drawing). Three-axes (pitch, roll and yaw) gyro sensors were attached on index finger, back of hand and forearm, from which the segment and the joint angular velocities were calculated. Outcome measure was the tremor amplitude defined as the root-mean-square mean of the vector-sum angular velocity at segments and joints. Two-way ANOVA showed that task and joint had main factor on the tremor amplitude (p < 0.05). Post-hoc analysis revealed that tremor amplitude at the metacarpo-phalangeal joint was not affected by task (p > 0.05). However, tremor amplitude at the wrist joint differed among the tasks (p < 0.05), and it was greater in the action tasks than in postural task. Tremor was greater at finger segments than at hand and forearm and it increased in action tasks. The results of this study would be helpful for the understanding and task-specific treatments of the essential tremor.

The concept of Green campus has recently become an issue with the fact that universities are classified as energy gluttons. This study clearly defines the meaning of domestic green campus, and explores the operating system of green campus and related associations. Then, it draws implications from the case of Harvard University. For the research, reports and research papers of the University are examined thoroughly, and detailed information were confirmed through visiting to the official home page and emails with authorities. The green campus support institutions of the United States are making efforts to integrate overlapping functions and create a synergy effect through internal interchange and information exchange, and substantive collaboration. Also, it is drawing active participation from students and faculties of American universities by publicizing and raising various methods of funding to manage them. The primary factors of Harvard University's success are: voluntary participation from all members, the coordinated operation of the administrative division to be the center of the green campus initiative and the cooperation of each department. Other critical factors of Harvard's success are their fundraising capability, and specialized management institution. The study has significance in that it draws applicable implications on domestic Green campus through in-depth analysis, which surpasses introduction of preceding studies.

This study aims to analyze middle school students' systemic thinking to express organic relations between different organ systems about the movement of food and air and teachers' reflective thinking about science teaching through their reflective journals after the lesson of digestion, circulation, respiration and excretion. Firstly, when investigating the moving route of hamburger eaten inside the body, students expressed the names, locations and forms of organs in the digestive system more than those in the circulatory system or the excretory system. When investigating the moving route of a painkiller taken inside the body, students seemed to have more difficulty in expressing the related organ systems than when investigating the moving route of other things, and they mostly drew pictures of organs in the digestive system as done for the moving route of hamburger. However, when investigating the moving route of water drunk inside the body, students mostly described organs in the digestive system but drew more pictures of organs in the excretory system, than when investigating the moving route of other things. When investigating the moving route of air inhaled inside the body, students mostly drew pictures of organs in the respiratory system, but the rate of their drawing pictures of circulatory organs was low. Secondly, this study analyzed one of the teachers' reflective journals, named Mr. Park. According to his journal, students showed different levels of understanding of organ names, depending on their degrees of familiarity with each organ, and in regard to the locations of organs, science teachers mostly aim to achieve learning objectives so much that they often forget to instruct the locations of organs in fact. As for the forms of organs, science teachers mostly spend so much time explaining the functions of organs that they often forget to describe the exact form of each organ.

The purpose of this study is to understand the experiences of adults after leaving the care of the institution. To accomplish this purpose, we have collected various data from participants who left child care institution more than five years ago and analysed these data through qualitative data analysis method. The results showed that three key themes namely, "isolation-helplessness", "being chained to their past", and "marching towards a better future". "Isolation-helplessness" is divided into "becoming a real orphan" and "fighting alone the unsupported". "Being chained to their past" are composed of "institution, a hometown that one needs to leave", "being marked as a institutionalized person" and "scars and marks". Lastly, "marching towards a better future" are grouped into "taking advantage of institutional experience", "helping each other", "drawing a fine picture of their future happiness" and "moving ahead sweeping aside all difficulties". Lastly, this study suggested political and practical measures to enhance wellbeing of adults that have left the institutional care.

Organizing and maintaining customer-based online communities are becoming increasingly important in current business environment. Companies can utilize the member generated contents in developing their products and services and they can establish close relationships with their customers. This paper investigates how customer-based online communities increase individual members' contributive behaviors. Drawing on the social psychology literature, this study adopts the concept of self-discrepancy rooted in self-identity and derive an index for self-discrepancy by using the differences between actual and virtual self-identities. Furthermore, this study examines the relationship between the self-discrepancy and the anonymity-related psychological factors (autonomy, recovery, and catharsis), which in turn influence quality and quantity of contribution. Analysis of 114 respondents showed that self-discrepancy between actual and virtual selves has two different sub-dimensions (personal self-discrepancy and social sel f-discrepancy) and each dimension has different effect on the quality and quantity of contribution through the mediation of autonomy and recovery. Notably, catharsis negatively influenced quality of contribution. Theoretical and practical implications are discussed based on the major findings.

The posters are the tools to communicate authors' idea with others by visual image and a little word. Every discipline has its own sign with specific meaning shared by the members of the discipline. Chemists and students learning chemistry, therefore, will communicate with each other by specific chemical signs (codes). The Korean Chemical Society has held the feast of drawing chemistry posters by students nationwide since 2004. In 2004 and 2005, more than three thousands of posters were submitted, and about one hundred and fifty posters were selected as the prize winners. The award was divided by the grade levels of elementary, middle, and high school. This study explores the codes of chemistry used in students' posters. With the analysis of the visual elements and the verbal elements of posters, 7 chemical codes were found such as the liquid, the experiment apparatus, the graduations, the chemical language, scientists, the earth and environment, and things around us. In addition, the differences were investigated on the grade levels, on awarded or non-awarded poster, and on the years. Educational implications of these findings are discussed.

Technological change leads to a value shift in human society. Various cultural experiences through the digital paradigm influence the expression of fashion. This article considers fashion film as a new form for presenting fashion and explores the distinctiveness of expression in digital fashion film. For the methodology, a literature review was conducted to examine the concepts and features of digital fashion film and metareality. Empirical research was also performed by drawing from Nick Knight's digital films, "Sans Couture", "#asif", and "The Elegant Universe" and by specifically analyzing the classification of the themes, visuals, and auditory expression. The results are as follows. The proliferation of fashion film has accelerated in the internet environment. New media in the digital era allows images to become more realistic and variable through immaterial conversion. Metareality is the notion of a reality beyond existence. A metarealistic image maintains the metaphysical nature of an object and transcends empirical appearance. It possesses immaterial, transboundary, and multidimensional features, and the image is realized by digital technology. The expression analysis identifies the metareality expressed in contemporary fashion film appearing as atypical forms, irrational combinations, and the playfulness of motion. It shows a positive attitude, transcending the immaterial limit of reality toward fashion. This study indicates how fashion as products challenges the metaphysical transformation in the digital era. The exploration of metareality in digital fashion film promotes a wider perspective and understanding of the concept of fashion.
