Tall building construction has been increasing due to the need to maximize land usage. It causes the increase of vertical transportation for workers and materials, which significantly affects the productivity and lifting planning, therefore, has to be made carefully based on the characteristics of the field. However, the existing method to calculate the number of lift is too simple to consider complex and various characteristics in tall building construction. Accordingly, we developed the model for selecting the best system of vertical transportation by using Queueing theory. To find out the situation of the queue of resources such as material and workers, a simulation program will be applied.

After Forest Service formed a forest welfare service system by life cycle in 2008, they established a variety of policy for promoting welfare of the people. In Forest welfare service plan(2013~2017) which recently the forest service department established to along with government's welfare policy, they introduce forest welfare service voucher linked to National welfare system to provide forest welfare actively to disadvantaged citizen. The purpose of this study is to setup a direction of forest voucher system, and to make strategies of forest welfare service voucher by research existing voucher system of government. A study conducts a qualitative research by use grounded theory without a quantitative research, because there is not a lot of similar cases with forest welfare service voucher. The subject of this study is experts of National Park Authority 's voucher management, forest service's Nature recreation management and relevant researcher institution. The research is conducted by interviewing the subject and by using grounded theory analysis. After processing an opening coding, categorization of opening coding, and axis coding, induce a direction of the forest welfare service voucher system.

For rational agricultural land use planning, it is quite necessary to get hold of land suitability precisely and to make decision on land use patterns accordingly. In the methodological viewpoint, objective and scientific evaluation techniques for land suitability classification should be supported for the systematic land use planning. As one of technical development approaches to rational land use planning, this study tried to frame a land suitability evaluation system for agricultural purposes. Evaluation unit is defined as a tract of land bounded by road, other land units and topographical features. And quantification theory was applied in the determination works of evaluation criteria. The administrative area of Namsa-myon(district), Yongin-si(city), Kyunggi-do(province) was selected for the case study. In order to check the feasibility of the evaluation system developed in the study, field check team, consisting of 2 government officers and 2 representative farmers, carried out evaluation works by observation on 148 sample land units, 10% of total 1,480 ones. Between estimated and observed results, there showed very good relationship of its multiple correlation coefficient, R=0.9467.

A pilot-scale sand-box experiment simulating a lateral of collector well used in riverbank filtration was performed, and hydraulic head distributions along the lateral were measured according to the various drawdowns at the well. The results of this experiment were compared to the predicted values obtained using a theory previously developed by Kim in order for its validation. This theory predicts the head loss in a large-scale lateral given the loss in a small-scale one, and to have actual values for comparison, the results from a lab-scale experiment previously performed by Kim were employed. Comparing the experimental values to the extrapolated value indeed confirmed the validity of the theory. A procedure to determine the hydraulic head distribution of a practical-scale lateral was also presented applying the theory to the experimental result of this study in an effort to show the process of lateral design for riverbank filtration.

This paper investigates morphological theory as an intellectual framework for research and design. The first part of the paper will review morphological studies in the fields of urban geography, urban planning and architecture, particularly in England from the 1940s to the 1980s. While urban geographers and planners were concerned primarily with town plans, building forms and land use, architectural theoreticians were more interested in the topological relationship between urban and architectural space. The underlying premises and principles of these two approaches will be reviewed. The second part of the paper will focus on typology in Europe and North America. The reinterpretation of typology by Italian architects helped to bridge the gap between individual elements of architecture and the overall form of the city. However, typological theory became less accessible in post-war England and the United States. After 1980, the debate on typology became muted by the onset of vague notions such as functionalism, bio-technical determinism, and contextualism. This paper will propose a redefinition of morphology as a heuristic device, in contrast with the dichotomic view of urban morphology and architectural typology. Morphology will be shown to combine the geometrical and topological; the intentional and accidental; the real and abstract; and a priori and a posteriori. The last part of the paper discusses the lack of comparative theories and methods surrounding the physical form of architecture and the city by Korea commentators. Empirically rooted facility planning, non-comparative historical studies, and iconographic criticism emerged as a central preoccupation of architectural culture between the 1960s and 1980s, a time when international debate on architecture and urbanism was most intense. This paper will give consideration to the built environment as a dynamic physical entity and space as an epiphenomenon of daily urban life, such that collaboration between urban designers, architects, and landscape architects is seen as both beneficial and necessary.

The vehicles play a significant role in modern people's life as economy grows. The development of car navigation system(CNS) provides various convenience because it shows the driver where they are and how to get to the destination from the point of source. However, the existing map-based CNS does not consider any environments such as traffic congestion. Given the same starting point and destination, the system always provides the same route and the required time. This paper proposes a path planning method with traffic prediction by applying historical driving information to the Fuzzy theory and Bayesian update. Fuzzy theory classifies the historical driving information into groups of leaving time and speed rate, and the traffic condition of each time zone is calculated by Bayesian update. An ellipse area including starting and destination points is restricted in order to reduce the calculation time. The accuracy and practicality of the proposed scheme are verified by several experiments and comparisons with real navigation.

The purpose of this study is : first, to examine factors of fashion show planning and production and to classify types of fashion show planning and production: second, to compare and analyze the factors through a case analysis to defined their differences. For the purpose, data are collected to compare and analyze from literature as well as the interview with fashion show planning and production companies in Korea. The result shows that all the factors are considered on a practical level except security and publicity among 15 factors presented in literature : the purpose of the show, target spectators, product selection, product prices, type of show, size, location, models, time of show, duration, theme, security, budget, and publicity. Show types are divided into national brands, designer brands, imported brands, and collections. The result of the comparison and analysis of the factors of the planning and production by type shows that factors vary greatly depending on the purpose of the show, target spectators, and form of the show and products. By analyzing the case study on fashion show planning and production on a practical level, the study recognizing the need of specialized development of fashion show planning in Korea's fashion industry, is a basic process of theory systematization for the planning and production in its marketing aspects, and will provide relevant theories in such aspects for those who want to enter into the field.

A novel integrated optimization method based on the Generalized Bender’s Decomposition (GBD) is proposed to combine both generation and transmission expansion problems. Most of existing researches on the integrated expansion planning based on the GBD theory incorporate DC power flow model to guarantee the convergence and improve the computation time. Inherently the GBD algorithm based on DC power flow model cannot consider variables and constraints related bus voltages and reactive power. In this paper, an integrated optimization method using the GBD algorithm based on a linearized AC power flow model is proposed to resolve aforementioned drawback. The proposed method has been successfully applied to Garver’s six-bus system and the IEEE 30-bus system which are frequently used power systems for transmission expansion planning studies.

This study explored the contents of practical knowledge about educational planning in early childhood curriculum as constructed by kindergarten teachers at early career stages and then developed a collaborative model of educational planning. Subjects were 6 teachers at early career stages. Using the ethnographic method, data were collected by in-depth interviews. Research outcomes were : (1) teachers specifically worked on 'difficulties in adapting to the teaching job', 'age of children that the teacher cares for', 'integration of theory and practice', and 'variety of actual teaching situations.' (2) A model for collaborative educational planning was constructed on the basis of review of the literature on teachers' knowledge, educational planning for early childhood curriculum, and learning of community.
