With increasing public concern for environmentally friendly agriculture, ecological aspect of landscape management is of growing importance. AHP (Analytical Hierarchy Process) analysis were conducted based on the delphi survey of 31 experts to evaluate the relative importance and the preference of landscape elements. Landscape components of organic farmland were classified into 2 landscape fields, 5 landscape types, 14 landscape units, and 37 landscape elements. Overall relevance score for the proposed landscape components were about 5.5 on the seven point scale. While the relative importance weight of cropland landscape field was 0.71, the weight of intra-structure landscape field was 0.29. Among the cropland landscape, relatively higher weight was assigned to farming system (0.47) and margins (0.31), as compared with hydrological system (0.22). In the farming system, crop (0.40) and farm land (0.39) were the most important landscape units. In the margins, higher weight was given to Buffer zone (0.44) and Trees (0.42). Biological habitat (0.43) ranked the highest score in the hydrological system. Preferable landscape elements were glass house, companion plants, rice paddy field, diverse crop species, small pond, and small river, which are representing ecological advantage of organic farming systems. This result indicated that the landscape elements identified in the study would be suitable to evaluate ecological aspect of rural landscape in organic farmland.

The research of combining virtual reality technology with the design elements of children's picture book education is a relatively new topic in virtual reality technology in recent years. Based on the combination of picture book design elements with virtual reality technology and the development of a children's picture book teaching game, this article analyzes the effectiveness of the application of virtual reality technology in children's teaching, and explores the usability of picture book design elements in teaching [1]. Through literature research methods, practical research methods and investigation research methods, this paper lucubrates the application of virtual reality technology in the design elements of children's picture book education so as to provide adequate theoretical and practical support for the research theme. The spatial positioning, vision, sound, and functional requirements of children's picture book games play a leading role in teaching. Practical statistics have proved that it is easier to promote children's mastery of teaching knowledge in a virtual environment. Moreover, use VR's game management function and setting function to solve the boringness of traditional education methods and the limitations of the teaching environment. The feasibility of game operation provides a virtual teaching platform system for children's education, and the teaching effect is remarkable.

The objective of this study is to suggest planning directions for rural landscape management and conservation. With wide literature review, the Rural Traditional Theme Village were selected as case study areas to search for the main elements according to various spatial types. The pictures taken from the site investigation were used for a questionnaire survey to understand and to find the value of rural landscape. Finally, we found out 25 items from 3 spatial type (rural life area, agriculture production area and natural environment area), and Analyzed the Preference of rural landscape elements.

The objective of the study is to verify the discriminatory power of valuation indexes in predicting IT small and medium sized manufacturing firms' going concern or firms' failure. The result of the study is expected to be useful in loan evaluation, investment decision, internal management decision making and business improvement. The results of study is as follows. First, we find that at least six valuation index elements are significant ex-ante variable which are discriminating between firms' going concern and firms' failure in IT small and medium sized manufacturing firms in various analysis' results. Second, these index elements are composed of 2 indexes-the ability of technology R&D, the efficient strategy of market penetration and six index elements explain 46% of the total variance. This explainable power of these indexed is similar to that of the existing 16 index elements. Finally, we find that the most important success factor of IT small and medium sized manufacturing firms are the ability of technology R&D and the efficient strategy of market penetration.

The purpose of this research is to identify the factors affecting user acceptance of mobile banking. To test the hypotheses, this research incorporates trust to extend the model. This study investigates the causal relationship among four factors; perceived ease of use, perceived usefulness, trust, and intention to use in mobile banking. This study also identifies the elements by which these factors are influenced. The result finds that facilitation condition and self-efficacy are significant elements affecting perceived ease of use. System quality, perceived ease of use and trust are significant elements affecting perceived usefulness, However, social influence is found to be not significant. System quality and perceived ease of use are significant elements affecting trust. Conclusively, perceived ease of use, perceived usefulness and trust are significant factors affecting the user acceptance in Mobile banking.

The purpose of this study was to investigate actual condition of the modern adaptation of interior elements (wall floor ceiling door & window) in traditional house. The examined objects were 316 pictures of residential interior spaces from the 5 different monthly magazines between Jan. 1993 to Dec. 1997 The results of this study were as follows; 1. Mostly they were either parital adaptation from the original or partially transformed adaptation rather than entire adaptation of the original 2. Of the traditional interior elements adapted in residential space only specific elements were being adapted. For example. partial adaptation from the original were oiled paper flooring(Jangpan) rice papered wall (Hanji) a ceiling finish that left the rafters and beams exposed (Yondunt-chonjang) and window or door frame which is vertical lattices accented with horizontal lattices grouped into three sections(Ttisal-mun)And partially transformed adaptation were wood flooring(Chang-maru) rice apered wall(Hanji) Yondung-chonjang wind or door frame of Wan character(Wanja-mum) 3. In regard to space the mostly adapted spaces were bedrooms rather than living or dining rooms.

This study investigates weekday/weekend characteristics of $PM_{10}$ and $PM_{2.5}$ concentration and metallic elements in Busan in the springtime of 2013. $PM_{10}$ concentration on weekday/weekend were 77.54 and $67.28{\mu}g/m^3$, respectively. And $PM_{2.5}$ concentration on weekday/weekend were 57.81 and $43.83{\mu}g/m^3$, respectively. Also, $PM_{2.5}/PM_{10}$ concentration ratio on weekdays/weekend was 0.75 and 0.65, respectively. The contribution rates of Na to total metallic elements in $PM_{10}$ on weekday/weekend were 38.3% and 38.9%, respectively. It would be useful in control effectively with management of urban fine particle to understand characteristics of fine particle concentration on weekday/weekend.

In this study, two extreme cases of compatibility of the horizontal displacements between the foundation and soil are considered, for which the pressure and settlements of the isolated footings and member end actions in structural elements are obtained using the three dimensional models and numerical experiments. The first case considered is complete slip between foundation and soil, termed as the un-coupled analysis. In the second case of analysis, termed as the coupled analysis, complete welding is assumed of joints between the foundation and soil elements. The model and the corresponding computer program developed simulate these two extreme states of compatibility giving insight into the variation of horizontal displacements and horizontal stresses and their intricacies, for evaluation of the influence of using the interface elements in soil-structure interaction analysis of three dimensional multiscale structures supported by isolated footings.

건설생산성에 영향을 미치는 많은 요소 중에서, 외부공사가 많은 건축공사는 기후의 영향을 많이 받는다. 지난 30년에 걸쳐 기후요소와 건설생산성간의 관계에 대한 많은 연구가 진행되어 왔지만, 대한민국의 지리적 특징을 잘 반영하는 연구는 미비하였다. 본 논문에서는 같은 유형의 공동주택 4개동($16\~18$층)의 데이터를 이용하여 골조공사의 건설생산성과 5가지 기후요소(온도, 습도, 낮 길이, 강수, 풍속)와의 관계를 단순회귀분석과 다중회귀분석을 통해 규명하였다. 단순회귀분석 결과, 기후요소 중 온도, 낮 길이가 건설생산성에 가장 큰 영향을 미치는 것으로 나타났고, 다중회귀분석으로부터는 기후요소에 의해 생산성을 예측할 수 있는 회귀식을 도출하였으며, 이러한 분석결과에 대한 검증과 활용 방안을 제시하였다. 본 연구의 결과는 공사관리의 기획단계 혹은 공정관리의 기초 자료로 사용될 수 있을 것으로 기대된다.
