  • The Giant Magellan Telescope (GMT) will feature two interchangeable Gregorian secondary mirrors, an adaptive secondary mirror (ASM) and a fast-steering secondary mirror (FSM). The FSM has an effective diameter of 3.2 m and built as seven 1.1 m diameter circular segments, which are conjugated 1:1 to the seven 8.4m segments of the primary. Each FSM segment contains a tip-tilt capability for fine co-alignment of the telescope subapertures and fast guiding to attenuate telescope wind shake and mount control jitter. This tip-tilt capability thus enhances performance of the telescope in the seeing limited observation mode. As the first stage of the FSM development, KASI conducted a Phase 0 study to develop a program plan detailing the design and manufacturing process for the seven FSM segments. The GMTO-KASI team matured this plan via an internal review in May 2016 and the revised plan was further assessed by an external review in June 2016. In this poster, we present the technical aspects of the FSM development plan.

  • The purpose of this study is to classify the building layout and plan types according to the urban location, use and function of civil and to analyze the characteristics by the type classified. After constructing a framework (Mathia type, Nagaya type, Detached House type) for analyzing Modern Private Housing Architecture in Gunsan, the research was conducted on 30 representative buildings, and a plot plan, a floor plan and elevation were created. After analyzing the relationship between the lot of land and the urban street, we classified the type of arrangement into Mathia type and Nagaya type which directly enter the building from the road, and derived the Detached House type which indirectly enters from the road. When we look at the use of the derived arrangement types, most of the Mathia type are commercial and residential buildings, and some of them are specially designed for commercial buildings. The Nagaya type appears in the form of commercial and residential house or residential private house, and the Detached House type is classified as residential style. As a relation with the urban street, the Mathia type and the Nagaya type are generally located on the main urban street, whereas the Detached House type is located on the small urban street. As a result of analyzing, the floor plan was changed according to the plot plan. The plan of the Mathia and Nagaya type are arranged to enter directly from the street, with commercial space being mainly located on the street, and the residential space being composed on the back or the second floor. the plan of the Detached House is a type that enters indirectly into the interior through a separate space (Courtyard), and forms an organic space between the residential interior and the front and rear yard. The purpose of this study is to investigate the Characteristics of a plot plan and a floor plan of Modern Private Housing Architecture in Gunsan by means of analysis considering the urban street, Uses of buildings, Construction method and the yard through actual measurement.

  • This study covers museum rest areas among the methods that reduce museum fatigue. The subjects of the study were Seoul branch of the representative National Museum of Contemporary Art and National Museum of Korea. These museums were compared and analyzed with The National Art Center of Tokyo and Tokyo National Museum. The first research step was the analysis of museums' floor plan, and the second step was the tracing survey of visitors' movement. The result of this study was as follows. The National Art Center of Tokyo and Tokyo National Museum had the rest space within the visitors' route along with good viewing areas. National Museum of Korea had poor viewing area even though there was the rest space withing the visitors' route. Lastly, Seoul branch of National Museum of Contemporary Art had the rest space out of visitors' route along with poor viewing areas. This study is meaningful in that it provided guidelines for museum space plan with visitors' route considered, so that their museum fatigue can be relieved along with the guideline that can be applied to space elements of rest space.

  • With a view to creating beautiful farm villages, this study aims to exploit space syntax and thereby establish a systematic plan for refurbishing common farming facilities in farm villages by expanding a remodeling plan that has so far been focused on farm houses to cover different villages as well as in spatial scope. For this purpose, the study has extracted a system of categories for common ownership facilities in farm villages and applicable elements needed for collaboration in the space of joint production by performing a comprehensive analysis of related literature for the purpose of researching the distribution of common farming facilities. Based on such categorization of applicable elements, the study conducted a field survey of the four types of farm villages such as suburban area (Hwaseong), inland farming-centered area (Jeungpyeong), coastal & plain area (Goheung), and mid-mountain area (Gangneung), through group discussions by participating researchers and field pilot surveys. Also, space analysis has come up with measurements based on the five criteria of integration, local integration, control, connectivity, and spatial depth. And a plan for type-specific remodelling of common farming facilities has been drawn up through standardization based on the values in integration for different villages and spatial depth for common farming facilities. The significance of the current study consists in identifying how the location of common farming facilities influences the characteristics of different villages in terms of spatial structure and then drawing up guidelines for planning their placement.

  • This study categorizes and identifies the characteristics of the living areas of rural dwellers through cluster analysis using mobile floating population data. As a result, rural areas in Korea were classified into 34 rural living areas, and 5 types of rural living areas were derived. Although the 'Suburban in Mega City Areas' and 'Suburban in Regional City Areas' derived through this study have advantages in terms of accessibility to large cities, they are important for rural space management as they can undermine the unique values of rural areas due to urban expansion. In addition, 'Unclassified areas' have low accessibility in the national space, and there is a need to provide their own settlement environment. The population of rural areas in Korea exhibited a phenomenon of widespread migration. This means that rural residents who depend on metropolitan areas are provided with SOC beyond administrative boundaries. Therefore, there is a need to move away from establishing a homogeneous regional plan that does not consider population movement. Through this study, it was possible to understand the rural living area formed by the population movement occurring in the rural area. This is different in that the existing studies classified the national space based on the interconnectedness between regions, beyond the limitations of categorizing regions with homogeneous characteristics based on endogenous indicators. At this point in time when the need for a rural space plan is emphasized, it is important to understand the living area of rural dwellers and to design an appropriate rural plan. Therefore, the establishment of a rural plan suitable for the region using the results of this study can increase the efficiency of the project for revitalization of the rural area and contribute to the creation of an attractive national space.

  • An inappropriate space zoning plan causes the unnecessary transportation of construction material and equipment among work areas and increases the disorder of work space. Space zoning is an essential operation management technique which contributes to reduce the process and/or operation idle-time. This paper introduces a method that computes the idle-times between construction operations (or processes) by using Web-CYCLONE. It allows computing with idle-times that affect the construction productivity. Using the idle time between operations and between processes, it computes the optimal number of zones and finds the optimal combination of zones that minimize the idle times. The method contributes to minimize the idle times relative to the operation schedule using complete enumeration. This paper presents the system prototype in detail. A case study is presented to demonstrate the system and verifies the validity of the model. It allows a project manager to establish space zoning plan that effectively segregates a project into optimal number of construction zones and to assign the constrained resources (e.g., laborer, equipment).
