The ingenuity of structural engineers in the field of tall and super-tall buildings has led to some of the most remarkable inventions. During this evolution of structural engineering concepts in the last 100 years, the technical challenges that engineers encountered were extraordinary and the advances were unprecedented. However, as the accomplishments of structural engineers are progressing, the desire for taller and safer structures is also increasing. The diagrid structural system is part of this evolving process as it develops a new paradigm for tall building design combining engineering efficiency and new architectural expression. The first appearances of this type of tall buildings have already been constructed and the interest of both engineering and architectural communities is growing mainly due to the many advantages compared to other structural systems. This paper presents a simple approach on optimizing member sizes for the diagonals of steel diagrid tall buildings. The optimizing method is based on minimizing the volume of the diagonal elements of a diagrid structure. The constraints are coming from the stiffness-based design, limiting the tip deflection of the building to widely accepted regulative limits. In addition, the current paper attempts to open the discussion on the important topic of optimization and robustness for tall buildings and also studies the future of the diagrid structural system.

The purpose of this study is to find the research trends relating to flipped learning through keyword network analysis. For investigating this topic, final 100 papers (removed due to overlap in all 205 papers) were selected as subjects from the result of research databases such as RISS, DBPIA, and KISS. After keyword extraction, coding, and data cleaning, we made a 2-mode network with final 202 keywords. In order to find out the research trends, frequency analysis, social network structural property analysis based on co-keyword network modeling, and social network centrality analysis were used. Followings were the results of the research: (a) Achievement, writing, blended learning, teaching and learning model, learner centered education, cooperative leaning, and learning motivation, and self-regulated learning were found to be the most common keywords except flipped learning. (b) Density was .088, and geodesic distance was 3.150 based on keyword network type 2. (c) Teaching and learning model, blended learning, and satisfaction were centrally located and closed related to other keywords. Satisfaction, teaching and learning model blended learning, motivation, writing, communication, and achievement were playing an intermediary role among other keywords.

We examine attributive possessive constructions in Korean in examples like wuli manwula 'my wife' and wuli nala 'my country', where an apparently plural pronoun wuli 'our' is used to convey the singular meaning of 'my.' An example like wuli manwula has been a frequent topic of joke, because it clearly contains the literal sense of 'shared wife.' This type of use and the frequent use of wuli in an exclusive my context led many to claim that these are products of Korean culture which emphasizes groups and group solidarity over individuality, the example wuli manwula being the extreme case. Drawing on the work of Taylor (1989; 1996), Croft (2001; 2003), Haspelmath (1997; 2003), and 윤재학 (2003), we compare the meanings of Korean and English possessive constructions and seek a more linguistically based account for the data. In particular, it is shown that (i) wuli in question is not really the plural form of nay 'my', (ii) the possessive constructions in Korean are more conservative and limited in possible relations than the English counterparts are, and that (iii) these two facts interact to produce the afore-mentioned uses.

웹 검색 분야의 대부분의 선행 연구들은 검색 질의를 살펴본 연구자의 판단에 근거하여 질의의 주제를 분석하였다. 그러나 웹 검색 질의의 주제 분야가 방대하고 다양하여서 이용자가 검색 결과에서 실제로 조회한 문서를 모르는 상태에서 연구자의 판단에 근거하여 질의의 주제를 분류하기에는 한계가 있다. 이에 본 연구에서는 1년 동안 네이버 이용자들이 입력한 질의를 기록한 질의로그와 질의에 대한 검색 결과에서 이용자가 조회한 문서를 기록한 클릭 로그에 근거하여 국내 웹 검색 질의의 형태 및 주제를 분석하였다. 질의를 형태별로 분류한 결과 사이트 검색 질의가 내용 검색 질의보다 많은 것으로 나타났다. 또한 이용자들이 전반적으로 가장 많이 검색한 주제는 컴퓨터/인터넷. 엔터테인먼트, 쇼핑, 게임. 교육 순으로 나타났다. 본 연구의 결과는 인터넷 포탈 업체들의 효과적인 컨텐츠 구축 및 효율적인 검색 시스템 개발에 기여할 것으로 기대된다.

This study is intended to develop a CAI program on the topic of flowing rivers and to investigate how 4th grade students' concepts of it change through this program. The CAI program is made using the GREAT II copyright tool based on a typical 4th grade science Korean textbook. This program consists of 5 sections, which are introduction, rain waters, running waters, river waters, and activity. All contents are animated. Students are 30 4th grade students. One instrument is used how to investigate the concept change of the flowing rivers. The instrument is called the Identification of Flowing River Concept Test(IFRCT, Appendix), which is of a two-tier type and has 8 items. Data are collected before and after the instruction using this program. Data are classified as a scientific model, a naive model, or a "no" model, based on criteria used by Vosniadou(1989). Data are compared. The results show that 4th grade students after the instruction using this program hold a more scientific model on the flowing rivers, than before the instruction using this program. Therefore, the author urges science teachers to use the CAI program to teach students about the flowing rivers.

Virtual ground modeling is one of key topic for real-time vehicle dynamic simulation. This paper discusses about the virtual 3D road modeling process using parametric surface concept. General road data is a type of lumped position vector so interpolation process is required to compute contact of internal surface. The parametric surface has continuity and linearity within boundaries and functions are very simple to find out contact point. In this paper, the parametric surface formula is adopted to road modeling to calculate road hight. Position indexing method is proposed to reduce memory size and resource possession, and a simple mathematical method for contact patch searching is also proposed. The developed road process program is tested in dynamic driving simulation on off-road. Conclusively, the new virtual road program shows high performance of road hight computation in vast field of off-road simulation.

Creative application in elaborate techniques can not only make design constructs productive but also can widen designers' figurative perspectives. There are many techniques applied in fashion design such as folds, patchworks, embroidery, dyeing, industrial treatment, etc. In particular, folds play a significant part in enlightening clothes uniqueness in contemporary fashion design. The primary purpose of this study was to make new suggestion for the production of high value-added fashion goods by reviewing and synthesizing fold expressions. Diverse fold designs were retrieved through a comprehensive literature review on topic-related books, fashion dictionaries, and fashion encyclopedias. Significant cases of fashion designs using folds were retrieved from fashion magazines uploaded from 2000. There are three types of folds applied in fashion design. (1) The folds by needlework like tucks, smocking, shirring, and trimming type folds(ruffle, frill, flounce, and ruche). (2) The folds by chemical or mechanical treatment like permanent pleats and crinkle. (3) The folds of formative dress like drape. From a comprehensive review of the folds design cases after 2000, the following characteristics of folds design were identified: (1) a highlighted role in the whole, (2) mixture and deformation of techniques and materials, (3) 3-D surface effect, (4) creation of a unique figurative beauty, and (5) expression of diverse fashion image.

The purpose of the study was to investigate relationships among food safety training, knowledge, and practices of school food service employees. A questionnaire that identified employees' food safety training experience, knowledge, and practices was developed based on a review of literature. A total of 341 Korean school food service employees participated in the survey; the final usable responses were 293 (a response rate: 86%). Statistical analyses were conducted using SPSS for Windows (version 10). Most of the respondents (> 86%) took training sessions on 'proper hand washing' and 'proper food storage temperatures', whereas less than 60% had training on 'monitoring procedures and corrective actions at critical control points'. The mean score of their food safety knowledge was 8.02 out of 11. The majority of the employees knew correctly 'potentially hazardous foods (93.2%)' and 'diseases and symptoms with which they are excluded from working (87.0%)'; less than 50% chose a correct answer for 'sanitizing food contact surfaces.' A chi-square analysis revealed that the employees' actual knowledge did not differ significantly by whether they had food safety training (at the level of a =0.01), except one topic 'diseases and symptoms with which they are excluded from working.' Their self-reported practice scores were rated as 2.98 - 3.39 based on a 5-point Likert-type scale (1-not at all, 5-always). Employees' food safety training should be conducted continuously and repetitively to improve the effectiveness of the training.
