  • Until now, we have a great progress in computer hardwares and computer softwares. Many people think these days as the information time or information society. Even though, we make a great progress in the computer science, we can not regard this society as the information society, if we do not accept the development of computer in our real life. In order to provide desirable residential environment for the information - society, it is necessary to review previous housing projects from the Industrial - Revolution to these days. Thus this study deals with limits of modern housings. This research also suggests a new housing concept for the information - society by reinterpretation of the Korean traditional houses. Use of space in the Korean traditional houses was mostly interpreted by the concept of sexual discrimination from Confucianism. However it is suggested in this study, that An-Chae is a home space for providing privacy of family and Sarang - Chae is a social space for providing social activity. Thus it is found that the Korean traditional house has been used as office as well as home. In this view, it is suggested that Korean traditional houses be the prototype of future house as a business space and also as a home space. In this study, 3 types of housing for the information - society are suggested; flat type, tower type and skip floor type. these houses have two entrances independently for the home space and the social space. Therefore each space has no interference with each other. Then one can do his own at home efficiently. He does not have to go to his office in downtown. One can relieve traffic congestions in the city and reduce air contamination.

  • This paper describes the structural solution for the design of a 29-story high-rise tower, which features a large office space above the Kabukiza Theatre. Kabuki is a type of Japanese traditional drama, and Kabukiza is the home building of Kabuki. GINZA KABUKIZA is the fifth generation of the Kabukiza Theatre, the first of which was built in 1889. In order to support 23 stories of office space above the theater - featuring a large void in plan - two 13-meter-deep mega-trusses, spanning 38.4 meters, are installed at the fifth floor of the building. Steelwork is used as a primary material for the structure above-ground, and a hybrid response control system using a buckling-restrained brace and oil damper is adopted in order to achieve a high seismic performance. This paper also describes the erection process of installing hydraulic jacks directly above the mega-truss at column bases, in order to keep the structure above the truss level during construction. The temple architecture of the previous Kabukiza is carefully restored by incorporating contemporary light-weight materials supported by steelwork.

  • A sliding mode fuzzy control (SMFC) algorithm is applied to design a controller for a benchmark problem on a wind- excited building. The structure is a 76-story concrete office tower with a height of 306 meters, hence the wind resistance characteristics are very important for the serviceability as well as the safety. A control system with an active tuned mass damper is assumed to be installed on the top floor. Since the structural acceleration is measured only at ,limited number of locations without measurement of the wind force, the structure of the conventional continuous sliding mode control may have the feed-back loop only. So, an adaptive least mean squares (LMS) filter is employed in the SMFC algorithm to generate a fictitious feed-forward loop. The adaptive LMS filter is designed based on the information of the stochastic characteristics of the wind velocity along the structure. A numerical study is carried out. and the performance of the present SMFC with the ,adaptive LMS filter is investigated in comparison with those of' other control, of algorithms such as linear quadratic Gaussian control, frequency domain optimal control, quadratic stability control, continuous sliding mode control, and H/sub ∞///sub μ/, control, which were reported by other researchers. The effectiveness of the adaptive LMS filter is also examined. The results indicate that the present algorithm is very efficient .

  • Standard safety management costs can not be applied to each site with same rate, it is very difficult, because it depends on the experience, work method, work kind, work progress schedule, and hazard level of each construction company. Therefore, this study is to find out hazard level of each work kinds through questionnaire and interview and investigate analyze the status which standard safety management costs have been used. Also, this study is to show reasonable rates of standard safety management costs in construction industry and to set up countermeasures against those problem after reviewing its status in korea with in Japan and Europe. The domestic system of standard safety management costs is not considered in the foreign country, while only related subjective items have been investigated and evaluated for this study. This study is to investigate eleven project kinds of domestic system, first, and to investigate eleven items of apartment bldg, office, civil work such as bridge, tunnel, dam, plant etc, secondly. Additionally, three items of gymnasium, railway, particular steel tower are investigated in this study. Also this study is to investigate and analyze performed costs of presently processing worker finished work so that it shows a new reasonable rate against standard safety management costs in construction industry, in order to make basial data and material to be systemized.

  • Rice Blast is the most devastating disease causing major yield losses in every year worldwide. It had been proved that using resistant rice varieties would be the most effective way to control this disease. Molecular screening and genetic diversities of major rice blast resistance genes were determined in 192 rice germplasm accessions using simple sequence repeat (SSR) markers. The genetic frequencies of the 10 major rice blast resistance genes varied from 19.79% to 54.69%. Seven accessions IC337593, IC346002, IC346004, IC346813, IC356117, IC356422 and IC383441 had maximum eight blast resistance gene, while FR13B, Hourakani, Kala Rata 1-24, Lemont, Brown Gora, IR87756-20-2-2-3, IC282418, IC356419, PKSLGR-1 and PKSLGR-39 had seven blast resistance genes. Twenty accessions possessed six genes, 36 accessions had five genes, 41 accessions had four genes, 38 accessions had three genes, 26 accessions had two genes, 13 accessions had single R gene and only one accession IC438644 does not possess any one blast resistant gene. Out of 192 accessions only 17 accessions harboured 7 to 8 blast resistance genes.

  • The purpose of this study is to survey its characteristics through analyzing brain-wave activity in the scientifically-gifted and general children in the problem-solving process. The subjects of this study were 6 elementary school students, who are attending the institute of education for the gifted belonging to the regional office of education and 6 general children in the same region. The analysis was performed targeting total 12 people. As the task for measuring brain wave is Hanio tower, it is the effective task of researching into the problem-solving process. As the equipment of measuring brain wave is EEG System, it used equipment that was developed in Australia. The analysis of data was minimized noise. As a result of research, the gifted children are excellent in stable level compared to general people in a stable situation with opening the eyes, thereby being able to be known to be high in preparatory level for learning. This can be seen to be indicated as a result that the effect of learning is excellent due to being high in preparatory level for solving problem. Also, even in the process of performing task, the brain-activity level in the gifted children is high, thereby having been able to know that ${\alpha}-wave$ is formed that is significantly high in the regions of frontal lobe and occipital lobe. Accordingly, given developing task that is high in brain activity level of the gifted children, the higher educational effect will be able to be expected.

  • An essential measure to prevent healthcare-associated infections (HAI) is to develop a consistent system of surveillance, thereby promoting a reliable situation diagnosis to perform efficient control for the problem. Patient-to-patient transmission of pathogens within the hospital plays a substantial role in the epidemiology of HAIs. Contamination of healthcare environments commonly occurs, including facilities surfaces (e.g., bed rails, bedside tables), drinking water, cooling tower water, endoscopic instruments, food, airborne, endotoxin test, sterile test and medical equipment, with pathogenic organisms. In addition, epidemiological analysis is performed by multi locus sequence tying, pulsed-field gel electrophoresis for active surveillance. Therefore, an environmental surveillance culture test for prevention improves patient safety and blocks infection agents. Effective infection control and increased safety are possible by controlling the national infection control system. In conclusion, this study contributes to an effective infection control system through the standardization of active surveillance culture laboratory and secure expertise as infection control specialist. The primary objective of the standardization is to improve the safety of the nation's healthcare system by reducing the rates of HAIs.

  • Last year, the Moon Jae-In administration made an attempt to abolish the presidential security office overseeing the presidential security and to transfer the work to the presidential security service under the National Police Agency. Currently, all of the G7 nations maintain a security system spearheaded by the police, so the policy of transferring the presidential security to the National Police Agency may be discussed. However, it is necessary to focus on the following reality. First, the current presidential security system is consisted of the overlapping security organizations classified into (1) inner ring of the presidential security agency, (2) middle ring of the police agency, and (3) outer ring of the capital defense command. If the presidential security agency is abolished, a vacuum will result as per the principle of class. Second, for the efficient security guard of the President, currently, the presidential security agency at the Presidential Security Safety Measure Committee plays the role of coordinating the tasks. If the National Police Agency becomes the control tower of the presidential security, whether command will be available for the military and diplomatic aspects of the presidential security work should also be considered. Third, Korea is currently in a truce with North Korea, so there is a big difference in terms of the security environment with such G7 nations as the UK, Germany, France, and Japan.

  • To obtain basic information on the breeding of early maturing, short plant height rapeseed varieties, the following 7 varieties, Isuzu, Miyuki, Norin 25, Rang, Yongdang, Cresus and Tower were used in diallel crosses in 1979. Maturing date, plant height and grain weight per plant for the parents, $F_1$'s and $F_2$'s of the 7 x 7 partial diallel crosses were measured in 1981 for analysis of their genetic behavior. The results obtained are summarized as follows: 1. The days to maturing of $F_1$'s showed complete dominance for early maturing, and both additive and dominance genetic variances were significant. Number of effective factors in $F_1$'s was 3, but in $F_2$'s was 1. The degree of dominance in $F_1$'s was partial, while in $F_2$'s was complete. Both broad and narrow sense herita-bilities in $F_1$'s was high, while in $F_2$'s was low. 2. Yield per plant in $F_2$'s was controlled by additive component of genetic variance only, but $F_1$'s was different. The degree of dominance in $F_1$'s was complete, while in $F_2$'s was partial. The direction of dominance showed almost complete dominance over high yield and three effective factors was estimated. Yield per plant was controlled by recessive genes. 3. The plant height was controlled by both dominance and additive variance. Dominance was directed toward tall plant height. Number of effective factors was 2, and broad and narrow sense heritability were high in the plant height.
