The purpose of this study is to analyze space composition and size of the Master Zone in the apartment unit plan. For this, we analyzed 435 samples by searching web-sites of the 5 main construction companies. The major results of this study are as follows. 1) Master Zone is organized 4 spaces such as main room, bathroom and make-up & dress room. Six types of Master Zone are classified with the composition of 4 spaces. 2) The size of the Master Zone is increased in proportion to the square meter. But the range of the ratio is small range of fluctuation as 20%${\sim}$30%. 3)The size and ratio of the each spaces of the Master Zone are analyzed. The size of bedroom is increased but the ratio is decreased. The size of bathroom is increased but the ratio is regular as 4%${\sim}$5%. The size of make-up and dressing room is generally increased but the range of the size and ratio is the most extensive. Through this analysis and research, this study would be provied the basic data for actual housing planning and to contribute to future trends of apartment houses.

The Master Plan of Natural Environment Conservation in Korea by Ministry of Environment has been carried out since 1986. The 2nd 10-year survey started in 1997, and there are three major parts in the Master Plan : First, the basic natural environment survey, second, sites in special features of ecological characteristics such as uninhabitable islands, wetlands, etc, and third, biological species featuring status of habitat, and population dynamics. However the information in the Master Plan is very fragmented and collected data are not so abundant due to insufficient man-power and unsynchronized survey time/season. In this regard this paper examined the similar National Biological Survey in USA and compared the differences with the Master Plan in Korea. The Master Plan in Korea should separate the management zone based on hydrological characteristics, and in each zone we should set a management goal in the long term basis. Secondly the species list is not so meaningful that we must concentrate more on research activities. In each taxonomical group we set up hypotheses and research goals. Thirdly local residents and communities should be involved in research so that enhanced biological diversity should benefit people in areas. Lastly legislation and laws should be reexamined and rectified to provide information to the managers that deals with natural resources, expecially when conflicting with economic matters.

A pig-specific real-time PCR assay based on the mitochondrial ND5 gene was developed to detect porcine material in food and other products. To optimize the performance of assay, seven commercial TaqMan master mixes and two real-time PCR platforms (Applied Biosystems StepOnePlus and Bio-rad CFX Connect) were used to evaluate the limit of detection (LOD) as well as the PCR efficiency and specificity. The LODs and PCR efficiencies for the seven master mixes on two platforms were 0.5-5 pg/reaction and 84.96%-108.80%, respectively. Additionally, non-specific amplifications of DNA from other animal samples (human, dog, cow, and chicken) were observed for four master mixes. These results imply that the sensitivity and specificity of a real-time PCR assay may vary depending on master mix and platform used. The best combination of master mix and real-time PCR platform can accurately detect 0.5 pg porcine DNA, with a PCR efficiency of 100.49%.

The defense IT master plan is the plan for promoting defense informatization and is established by the Ministry of National Defense every five years. In addition, an implementation plan has been established in accordance with the master plan every year to promote the informatization project. However, since there is no systematic methodology to check and analyze the master plan comprehensively, it is difficult to judge whether the goals suggested in the master plan are achieved, and continuous monitoring of the project is limited. This study proposes a concept and framework for defense IT investment management and proposes a methodology for examining and analyzing the progress of the defense IT plan by referring to the U.S. Department of Defense's IT Plan and the performance management structure of the national IT master plan. As a methodology for managing defense IT investment, we propose an IT investment management code system from the perspective of an IT portfolio and verify its applicability through case studies. The results of this study are expected to improve the defense IT performance management system and improve the efficiency and effectiveness of the defense IT project.

This study conducted a management system and business analysis related to urban and architecture in local small and medium cities. The current status of the management department of the master plans, which were established based on the laws related to the spatial environment and implemented projects based on them, was analyzed, and the problems were derived. The basic urban master plan of the local government is classified as a hierarchical higher plan than other plans established within the same city, but there was a problem in that the timing of each plan was different. As a problem, the contents of the sub-plan were not included in the upper plan, or the opposite phenomenon occurred. In addition, the management entity of the master plan and sub-projects was different. To solve this problem, it is necessary to form a consistent structure of systematic planning and management subjects. In addition, in the future planning stage, it is necessary to establish a master plan establishment system according to hierarchies. This study is meaningful in that it can be used to establish a master plan establishment system according to hierarchy in the future planning stage and to establish the same management entity as the master plan in the projects stage.

Conditions are discussed for operating a dissymmetric human master-small (or micro) slave system in best (large position gain-small velocity gain) conditions allowing higher operator dexterity when real effects (joint compliance, link flexion delay and transmission distortion) are taken into account. It is shown that position PD feedback law advantage for ideal case no longer holds, and that more complicated feedback law depending on real effects has to be implemented with adapted transmission line. Drawback is slowdown of master slave interaction, suggesting to use more advanced predictive methods for the master and more intelligent control law for the slave.

In master-slave teleoperating system, it is important that the system has good maneuverability. In this paper, it is addressed an adaptive learning control method applicable to the master-slave system. This control scheme has the ability to estimate uncertain dynamic parameters included intrinsically in the system and to achieve the desired performance without the nasty matrix operation. The proposed method is applied to a master-slave teleoperating system composed of two SCARA robots and verified experimentally.

The objective of this paper is to design a force feedback controller for bilateral control of a master-slave manipulator system. In a bilateral control system, the motion of the master device is followed by the slave one, while the force applied to the slave is reflected on the master. In this paper, a fuzzy logic controllers applied to the system. Using the fuzzy logic controller, the knowledge of the system dynamics is not needed. Simulations and experimental results show the performance of the proposed controller.
