During road construction, minimizing haul and return distances as well as keeping a balance between cut and fill quantities are two of the key tasks for earthmoving operation planning. The result of the earthwork planning has a significant impact on the construction cost and duration. Although there have been research efforts regarding optimized earthwork planning using linear programming, the current practice of selecting earthwork planning methods typically depends on a field manager's intuitive and/or experimental knowledge. Furthermore, there is no system considering earthwork influential field factors including the transportation distance, the earthwork quantity, and the recycling ratio of earth volume. Therefore, this research focuses on the development of such a model for planning the optimized earthwork to increase the efficiency of a road construction. The proposed model is developed based upon the transportation problem method which is a part of Linear Programming. The application result of optimization model on a case study shows that the duration and cost for earthwork ha sbeen reduced approximately 19% and 11% respectively

A construction temporary work is main process and importance trade section. It has many works and facilities such as temporary transfer equipments which tower crane, and lift, and architectural temporary facilities which temporary office, temporary warehouse, and site test laboratory, and construction temporary equipments which scaffoldings, work plates, construction supports, and forms to set and to use in under construction and to remove in the end. A technology system of construction temporary has very low availability of field works and needs improvements in Korea as construction site has a quick response about new requirements. This study is organized existing technology systems and new technologies for field works, and developed breakdown structure of construction temporary technologies to be a basic of temporary technologies as review with site managers. For this, it will improve to be a knowledge and information system as a research of a performance and an availability about a construction temporary technology index.

The results of the study are as follows. First, this study defines management teacher of industry-academy cooperation as 'a person who career teachers in charge of career guidance, NCS-based field practice, establishment of industry-academia-government relations, external business administration, industry-academia cooperation administration, teaching subject class'. Second, the job of management teacher of industry-academy cooperation were total 7 duties and 80 tasks. Third, the importance, difficulty, and frequency of each task are classified into high (A), normal (B), and low (C) according to degree. Finally, this study make out a DACUM chart of management teacher of industry-academy cooperation of specialized high school based on the results of DACUM job analysis. And knowledge, skills, tools, and positive behaviors, future trends/concerns about management teacher of industry-academy cooperation of specialized high school were presented.

The purpose of this study was to identify the duties and tasks of pre-service health education teacher in elementary school using DACUM method. DACUM workshop was conducted for the fourth year nursing students located in J province who completed a health teacher teaching course and performed practical training course in elementary school. By carrying out DACUM workshop duties, tasks, task-specific importance, difficulty and frequency were analyzed, and were derived with the knowledges, skills, attitudes, tools, and future prospects on job requirements and characteristics. The derived job analysis information was verified the content validity from 6 field experts in school and 2 professors of education. Based on the result, DACUM chart was developed. DACUM chart was consisted of 6 duties and 24 tasks, knowledges, skills, and attitudes for job performance were derived. The result of study showed that health care in elementary pre-school health education teacher practicum was listed as the most important duty. Teaching and writing skills were presented to practice basically. Because the importance and role of the health teachers in school are considered necessary, it is considered to increase institutional support for the development of health education program and the improvement of educational environment.

Demand of industry site should be accepted for effective job education of college. This study was conducted to analyze the demand of industry and the need of education, and to reflect them in the customer demand education of Department of Cadastral Information, Shingu College. DACUM job analysis method was adapted to conduct this study, and pannelists who work in surveying and GIS industry had been invited to analyze systemically the job of related industrial site. As results, the job-task model and Knowlege Skill Tool matrix was derived by analysis of job and task of industrial site. This job analysis data can be used to develop the curriculum or the program of surveying and GIS education, or to revise existing curriculum.

This paper presents a model of Task-Ontology for small unit operations(SUO) such as nongovernment organizations Despite the rapid development and extension of NGO in domestic area, most have insufficient structural domain resources in existence and underestimate the importance of information management. To improve the citizen's participation and to activate the conjoint actions among the NGO, which are critical to its social role-playing in global society, the modeling Task-Ontology is ultimately intended to implement the knowledge management system of NGO. In the perspective of ontology competency, not only the analysis of resources in vary, but also in-depth Interviews with the NGO practicing personnels and subject experts, and also the intensive observations of task-processing are required for the knowledge acquisition.

This paper aims to uncover and discuss characteristics of citizen participatory transdisciplinary research which has been gaining momentum in recent years in the form of social-problem solving R&D program and sustainability science research. Two key questions are examined. One is related to the mechanism of cooperation in knowledge production among participants, namely scientists and citizens(extra-academics), while the other is examining whether the output of participatory research activity is more than journals or patents. Diverse strands of literature on knowledge and knowledge production including Mode 2, Learning modes and the notion of co-production of knowledge and social order are drawn and critically reviewed to elucidate the characteristics of citizen participatory transdisciplinary research.

The efficient vertical lift planning has been brought into relief in high-rise building construction projects. Particularly, the selection and stability examination of the tower cranes is the most important elements in vertical lift planning. Therefore, professional knowledge is needed to full fill the site condition for the plan. However, there are short of the number of specialists and information about tower cranes. This study proposes a system for the selection of the optimum tower cranes (Opt-TC) in high-rise building construction projects. The Opt-TC can give the selection and stability examination of tower cranes at once in real-time.

본 연구에서는 21세기 무용예술 창작환경변화에 따른 실제 행해지는 안무법들을 알아보는데 그 목적이 있다. 이를 위해 먼저 안무의 사전적 의미, 학술연구에서의 안무의 개념을 살펴보았다. 그리고 2000년도 이후 댄스포럼 잡지 중 5년 단위로 잡지를 선정하여 이로부터 안무가들의 인터뷰를 수집 후 안무방법에 대한 언급이 있는 기사들만을 추출 하여, 21세기 현장에서 이루어지는 안무의 실제에 대해 정리하였다. 안무의 사전적 개념은 17세기 안무의 개념과 크게 다르지 않았고 저작권에서도 동작의 형으로만 그 범위를 제한하였다. 20세기에 들어 움직임의 창작 뿐만 아니라 작품의 연출에 까지 그 범위가 확장되었다. 21세기의 안무가들은 사전적 안무의 개념에 집중하는 경우도 있었지만 주로 안무 작업 시 작품 전체의 연출에 집중하였으며, 움직임은 주로 무용가들과의 소통을 통해 창작하였다. 융 복합 환경으로 변화해가는 창작환경의 변화를 고려하였을 때 지식재산권의 문제를 고려한 안무 개념의 고찰에 대한 많은 연구들이 진행되어야 한다.
