The goal of this paper is to analyze the Freedom Center Apacle in Seoul designed by Kin Soo Geun who was a leading architect in Korean Modern architecture. Freedom Center was built in 1963, that was the largest monumental building to support military regime during cold war period in Korea. This paper deals with historical background of construction of Freedom Center and its characteristics compared to similar monumental buildings, especially Corbusier's Chandigar and Kenzo Tange's Hiroshima Peace Center. The Monumentality in Freedom Center came from the reference to these two buildings and its site plan. This paper tried to show how similar the layout of buildings between the Freedom Center and Peace Center. The origin of the sublime aura in Tange's linear layout of Peace Center is from Japanese Famous Shrine(Jinku). Kim translated it to serve the ideological purpose to protect from socialist regime in the name of freedom. Its over-scaled roof and weak contents showed Freedom center was a kind of theaterical setting belong to formalist building. But in spite of its symbolic and representational gesture its also had a architectonic physical quality to make it a monument. The change and duration in time testified the autonomous power of architecture in Freedom Center. Freedom Center was also important for using the exposed concrete and its superior finish. It was influenced not from western way of Benton Brut which was usually called New Brutalism but Japanese way of treating expose concrete. In spite of its limits Freedom center achieved new trend and sensibility in Korean Modern Architecture.

Recently, landscaping construction has played a significant role in enhancing the quality of life for citizens by creating and maintaining outdoor spaces. However, landscaping projects vary in material procurement depending on the contracting method, and they also present various challenges in defect occurrence and defect rectification due to their specialized nature. In this study, we classified different types of projects based on material procurement ratios and conducted on-site assessments of defect status by specific processes. We also analyzed the itemization of material ratios and defect rectification costs. The results revealed it was found that projects with a higher proportion of government-provided materials had the poorest defect status in terms of planting works and also incurred the highest defect rectification costs. Moreover, conflicts concerning the responsibility for defects arose. Currently, there are no specific guidelines for setting standards for the proportion of government-provided materials in landscaping construction contracts. Furthermore, there is ambiguity in the management of defect rectification. Therefore, it is necessary to establish a systematic landscaping construction contracting framework by providing institutional guidelines tailored to local governments or the circumstances of contracting entities and to conduct thorough reviews of construction processes.

Code excited Linear Prediction(CELP) vocoder exhibits good performance at data rates below 4.8 kbps. The major drawback of CELP type coders is their large amount of computation. In this paper, we propose a new pitch searching method that preseves the quality of the CELP vodocer reducing computational complexity. The basic idea is that pregrasps preliminary pitches about signal and performs pitch search only about the preliminary pitches. Applying the proposed method to the CELP vocoder, we can reduce complexity about 90% in th pitch search.

Purpose: This study aimed at improving the indoor environment of the office building by measuring the indoor environment and conducting a survey. Method: The measurement was conducted from January 13 to March 16 in 2012, targeting 44 sites in same office building located in Seoul, South Korea. The lists of measurement such as dry-blub temperature, relative humidity, formaldehyde (HCHO), asbestos, carbon monoxide (CO), carbon dioxide (CO2), volatile organic compounds (VOCs) and particle pollution (PM10) were measured. In addition, illuminance which belongs to light environment and noise in sound[acoustical] environment were measured respectively. Result: The buildings showed overall pleasant conditions. In terms of the thermal, air, sound, and visual environment, each measurements were satisfied with the requirements in standard, within pleasant ranges, except several sites. However, the survey results were revealed that the office workers were mostly dissatisfied with their indoor environment. Given that the measured values were mostly within standards, the results of survey might have resulted from a compensation mentality biased toward the subjects in psychological terms.

Non-curable rubberized polymer asphalt waterproof coating materials in Korea and China are manufactured without advanced quality control techniques and common standard, And they are exposed consistent water leakage problems. Import and application of Korean waterproofing products and installation methods is difficult in the present situation as the Chinese standard(JC/T 2428) is different in nature with the Korean counterpart products, And quality assurance is inevitable based on mutual standards. In order to resolve this issue, alternatives such as using standards provided by the ISO (International Organization for Standardization) are generally employed, but there is no such ISO standard as a waterproof material for non-curable rubberized polymer asphalt material. Furthermore, it is unreasonable to develop the ISO standard for rubber asphalt seals for exchange in terms of time and cost. This study proposes that the establishment of a quality standard that can be applied for both countries will be required via an joint international standard that outlines the properties of materials if applied in mutual trade exchange.

The 1-methylcyclopropene (1-MCP) is the gaseous ethylene action inhibitor, which delay senescence and wilting by blocking the binding of its receptors. We investigated the effects of 1-MCP with different treated duration (0h (Control), 1h, and 4h) in cut flowers of Eustoma grandiflorum 'Voyage' and Cymbidium 'Lapine Hat'. The relative water uptake increased by 14.5% than control (9.8%) and the flower diameter maintained high from 3 to 11 days in 1-MCP treatment for 4h in E. grandiflorum 'Voyage'. The relative fresh weight was averagely high in 1-MCP treatment for 4h, however, the vase life was not significantly different in both cut flowers. Since the effects of 1-MCP treatment was differently responded by plant species and cultivars, interacted studies of duration and levels of 1-MCP are needed for the pronounced effects of postharvest quality.

As companies seek lower cost and superior quality at the same time, which depend on improvement in product architecture, they need to critically consider product architecture as part of corporate strategy. This research investigated how product architecture and organizational capability affect innovative outcomes with using architecture framework. As a result, we were able to find out Korean shipbuilding company has put much effort on integral works such as development of FGSS(Fuel gas supply system), PRS(Partial Re-liquefaction System) and weight lightening for improving fuel efficiency. And this kind of integral ability was realized by organizational capability of Korean shipbuilding company based on interactive relationship with plant workers. In contrast, Chinese shipbuilding companies focused excessively on the standard design and the convenience of research and development made by central government, overlooking the need for fine-tuning. As a result, the fuel efficiency of Chinese LNG ships turned out to be 7-10% lower than those of South Korea with using the same modules and components.

The H.264 standard is widely used due to the high compression rate and quality. The deblocking filter of the H.264 standard improves the quality of images by eliminating blocking artifacts of pictures, and it requires a lot of computation. We propose a new hardware architecture for the deblocking filter with pipelined architecture, 1-D filters which support both horizontal and vertical filtering and efficient memory management. Four memory blocks are configured for the efficient storage and access of the current macroblock and adjacent referenced sub-macroblocks, and the pixel data from the motion compensation unit can be transferred without waiting during the computation cycles of the deblocking filter. The number of computation cycles and the hardware area are reduced using the proposed architecture, and the performance of the H.264 decoder is improved. We design the deblocking filter using Verilog-HDL and implement using an FPGA. The designed deblocking filter can be used for decoding HD quality images at 77 MHz.

In a hybrid architecture that combines the technological advantages of P2P(peer-to-peer) and cloud computing, it is possible to efficiently supply resources and allocate loads. In other words, by appropriately utilizing the processing power of the players constituting P2P as well as the server in the cloud computing environment, MMOG(Massively Multiplayer Online Game) can be configured that considers the scale of economic cost and service quality. In fact, the computing power and communication bandwidth of servers in the cloud are important demand-based resources. The more it is used when renting, the higher the cost, while the quality of service improves. On the other hand, if the player's processing power is utilized a lot, the quality of service deteriorates relatively while the economic cost decreases. In this paper, a bandwidth adjustment technique between servers and players for MMOG based on this hybrid structure is described. When the number of players running at the same time increases, the players' actions are appropriately distributed to servers and players to effectively utilize the server's computing power and communication volume. Simulation results show that in the MMOG based on cloud and P2P hybrid architecture, the bandwidth of the server is proportionally decreased as the bandwidth directly handled by players is increased.
