A yard in a container terminal is a temporary storage space before containers are loaded onto the target vessel or delivered to consignees. For improving the utilization of the space in the yard and the efficiency of loading and discharging operations, it is important that operation plans must be carefully constructed in advance. A heuristic method is suggested to solve operation space planning problems considering workloads on handling equipment as well as space availabilities. The operation plans in this paper includes quay crane (QC) schedules and space plans for multiple vessels considering the workload in the container yard of container terminals. This paper evaluates the effectiveness of a space planning method and the performance of a new QC scheduling method using a simulation model.

Literature has showing a phenomenon of the society and the year's issue for a long time. Many critics used index to do not only understand the years' but also just literature. That is, the literature was an essential method to express the society. However, it can be different for each people to have a view point for the literary work. Therefore, people has a self-analysis for the work, and the activity affect that the it can be difficult for people to public their interest for the literary. In this paper, we make new cyber space for social network of the literary and propose a framework that people can discuss their opinion for the literary work. In that time, we make a literary work as digital content.

This work is a interactive digital art work which used the multiplex of jitter. It is an work which used a cross concept of two images. This work shows two kinds of images. One is on the wall through the gap of fluorescent lamp screen, and the other is on the fluorescent lamp screen. Two images are intercepted and comes out to the length as the multiplex of the jitter. The appearance of the spectator be recognized on the fluorescent lamp screen or on the wall, by two branch image which comes out intersecting of a length with multiplex function of the jitter. Two branch features of the image which it produces and the spectator which is input at real-time is equally divided, or in impression of juxtaposition goes in the spectator. It expresses the duplicity of the human being, with physical existence space divides the time space which we feel and there is a governing grammar which is different with each other and to express the thing it becomes. It used the image of the screen which it produces with the fluorescent lamp and cross concept.

The purpose of this study is to investigate the information behavior of the junior high school students in the public library and to find the effectiveness of the behavior analysis using a cognitive work analysis(CWA). Data was collected through a dept interview and an observation method. Results show that the students had four constraints when they searched materials for reports: relevant materials for reports, limitation of materials, opening hours, use possibility. There are three behavior types. A type is that students find materials on the shelf through searching an online catalog, then make a report using reading the materials. B type is that students find materials on the shelf and check out the materials. C type is that students find materials and check out them by library staff help. CWA can be used for the information behavior research on the library space. CWA can, however, apply for space redesign when various researches would be conducted about the information behavior.

The rice mill occurred from modernization process of the farming village. It comes to follow in intention of the architect and is not the position building. By the user of the building it comes to follow necessary and it is a position thing. The like this rice mill was the community center of the village. Also the material which is unique and form quality were land mark of the village. The object of research is the rice mill where it takes charge of a like this role. And the scope of research is 8 rice mills of Eomjeong Myeon Chungju City which is located in the northern Chungbuk area. The progress of research the documentary survey, actual measurement, question, field work it analyzed the construction quality which the rice mill keeps with base and it arranges. The results of study are follows; 1. conditions of location : The rice mill the entrance of the village, the crossroads system is formed most the place is doing in the place which well. 2. The inside composition of a space : In order to compose the work space and the store space efficiently the plane surface is doing a rectangular form. 3. Form of roof : The roof raises the efficient characteristic of the work where is not the design which is intended to be naturally formed from the space composition for. 4. Selection of material : Most it was a natural enemy and an utility, it selected the scientific material and it used.

Coworking spaces have been increasingly considered as a way of building an innovative entrepreneurship ecosystem and facilitating population inflow. This paper aims at identifying the concept and characteristics of coworking spaces and examining these various types in a regional context. Coworking spaces located or planned in small and medium-sized cities and rural areas in Japan and Korea are empirically investigated. Through the case study, this study provides implications for a model of coworking spaces being a creative community in a region. Specifically, it is necessary to have distinctive features only for the regional context-based coworking spaces. Moreover, this new spaces should act as a multi-functional, convergent space and a venue for regional innovation. In a fast-changing work environment such as telework, the region-based coworking spaces can be reconsidered as the place that provides an alternative work, play, learn, and rest platform. Creative people hoping for new work and lifestyle may flow into the region through this intermediator, and thus foster the interplay between the creative community and regional environment.

As the government has enforced recently the policies on the distribution of the housing, the construction cost of multi-family housing projects has increasingly become very sensitive and political issue. However, it is difficult to predict the construction cost in planning and design phase of the project because the Bill of Quantity of the multi-family housing projects was composed of breakdown structure based on each work package. To predict the construction cost in planning and design phase for multi-family housing projects in more effective and reasonable way, this study developed the cost breakdown structure based on spaces using Delphi method. The Cost Breakdown Structure (CBS) based on spaces for multi-family housing projects basically consists of three parts: (i) Building part; (ii) Non-building part; and (iii) Additional part. The characteristics of spaces in multi-family housing projects are fully taken into consideration. Then these three parts were subdivided into work packages in terms of work tasks. Additionally, the usefulness and effectiveness of Space CBS in this paper were validated by analyzing the BOQs of several collected sample projects and matching with Space CBS afterwards.

The purpose of this paper is to evaluate the efficiency of various solution techniques and propose new efficient solution techniques for space trusses. Solution techniques used in this study are three load control methods (Newton-Raphson Method, modified Newton-Raphson Method, Secant-Newton Method), two load-displacement control methods(Arc-length Method, Work Increment Control Method) and three combined load-displacement control methods(Combined Arc-length Method I , Combined Arc-length MethodⅡ, Combined Work Increment Control Method). To evaluate the efficiency of these solution techniques, we must examine accuracy of their solutions, convergences and computing times of numerical examples. The combined load-displacement control methods are the most efficient in the geometric nonlinear solution techniques and in tracing post-buckling behavior of space truss. The combined work increment control method is the most efficient in tracing the buckling load of spate trusses with high degrees of freedom.
