Data from live animal real time ultrasound (RTU) measures from 127 Hanwoo steers were used to assess nutritional physiology and relationship between RTU measures and real carcass measures represented meat quality. Traits considered were longissimus muscle area, fat thickness, and marbling score imaged and scanned using RTU by month and those of carcass measures at about 24 month of age. On this study, increasing pattern for longissimus muscle area would be closely related to growth pattern (p<0.01) and it of fat thickness would be related to quadratic effect of ages. Marbling score would be related to aging, that is, individual deviates of scores were distinctly characterized after 17 mo. even though they were started at about 11 mo. Correlation estimates between RTU measures and corresponding carcass traits were over 0.6 after 17 month of age for all traits considered and these estimates were high as 0.90 after 22 month of age. From this study, Real-time ultrasound measurement would be valuable after 15-17 mo. and measures at about 22 mo. would be helpful to decide age for slaughtering. To utilize these techniques for beef cattle breeding via progeny testing program, 15 mo. RTU measures would be efficiency rather than 12 mo. of other beef breeds. Further study to find genetic variation of RTU measures was needed to utilize these technologies for beef breeding.

As Korea-EU FTA has established, the strategy and counteractive measures of Japan have been rising. EU accounts for 33% of GDP and has a lot of population, which makes up 7.1% in the world. Besides, it has a great market, which, amounts to 4.3 trillion. Japanese government indicated that as Korea has established FTA with the U.S.A. and has negotiated with EU, the necessity to cope with in the field of automobile, machinery, and appliances is urgent. To recognize competitive areas in the market of EU between Korea and Japan, this paper focuses that we need to notice Japan's access toward EU and the present situation about trade and customs. Second, it investigates that Japan is in competitive with Korea in which kind of industrial area.

The measures for water quality improvement have been planned to introduce for several reservoirs which were badly polluted among the sites included in the Network of Agricultural Water Quality Survey (NAWQS). Considering conditions of circumstances around reservoirs, self-purification systems such as natural ecosystem, oxidation ponds with plants, grassed waterways, weirs, and manmade plant-islands are taking into account enhancing to trap nutrients in waters running off from agricultural lands. The Pollutant Run off Ratios were analysed to predict the effects of water quality improvement for self-purification systems. The cost of water quality improvement was evaluated. The correlation equation between cost and irrigation area showing high correlation coefficient was derived.

This paper considers a ring loading problem on RPR(Resilient Packet Ring), where RPR is recommended by IEEE802.17 Resilient Packet Ring working group for data optimized networks without the requirements of provisioning circuits. RPR is well suitable for metropolitan area network with two counter-rotating rings that multiple stations share the bandwidth, where the data and its corresponding control traffic is transmitted to the two opposite directional ring, respectively. One of the major concerns on RPR is to provide fairness among traffic requirements. The paper discusses several fairness measures and analysis ring loading problems for the fairness.

Over the past decade, major advances have occurred in both understanding and practice with regard to assessment and mitigation of hazard area associated with seismically induced soil liquefaction. In this paper, assessment of liquefaction resistance of soil are reviewed from the recent researches. In addition site characteristics investigation methods and tests for seismic design and liquefaction analysis are reviewed. Finally, introduction and characteristics of remedial measures against soil liquefaction are reviewed briefly.

This paper proposes a new measurement method of face region size for real-time serveillance systems. The proposed method consists of three steps. In the first step, it detects global face area based on the block-based difference images. In the second step, it measures the face region size using face color information. In the third step, it estimates the face position in the next input image using the trajectory of face regions. The experimental results have shown that the proposed algorithm measures the face size within 20％ relative error on average, which is a]towable for most surveillance systems.

Recently in Korea, noise is one of the most important social issues because the living standard becomes more higher. Railway noise is also annoying one in our society, although railway has very positive role in our country. The major measures for mitigation of railway noise in Korea are rail welding and installation of noise barrier on the noisy area. But these measures have its own limit for the calm and comfortable living environment. In Europe the railway noise problem has been treated more systematically and aggressively, there has been emission noise standard for Trans-European rail network. In this paper, the trend of noise standard for railway vehicles will be reported and the check point for our country will be discussed.

Noise and vibration generated at construction sites become serious issues because of bigger construction projects and growing use of heavy equipment. Especially in downtown construction, noise and vibration easily exceed the legal standards that can suffer the most of surrounding residents. The number of complaints by the residents who are exposed to the noise increases as their consciousness grows. However, the Korean regulations for the construction noise and vibration only present the overall limits for target areas and times zones, and this make it difficult to take effective measures. Also in rural area, disputes between construction sites and residents arise, but the dispute resolution or taking measures are difficult because clear standards concerning cause-and-effect, estimation of effective levels, calculation of damages, and future precautions and examples lack. This paper describes legal standards regarding the noise and vibration and presents judging standards for the physical damages. This paper also introduces example public complaints that happened at Daewoo construction sites to describe the problems in the existing law and further to enable smooth construction progresses by emphasizing the seriousness of public complaints.

The snow brings affluence if it is dealt with appropriately. but causes huge damages if it is dealt with improperly when it snows heavily. Following with the development of road transportation, tile snow causes damages by becoming a serious obstacle for traffic, increasing traffic accidents, causing damages to the road, and requiring a lot of snow removal expense. As farming in the winter becomes flourishing, damages to agricultural facilities and farm produces caused by the snow become bigger and bigger. Now in our country, heavy snow or heavy rain is likely to fall at anywhere and at any time without restricted to a particular area. Safety first is one way of practicing human respect. Disasters will disappear from our neighborhood if we adopt prevention measures and follow them thoroughly. And also this is the shortcut to achieve a welfare society.

As the importance of software measurement increases, there are more researches developing the new software measure. Given the importance of object-oriented development techniques, one specific area where this has occurred is coupling measurement in object-oriented systems. This thesis presents the coupling measure COM based on the methods and OOC based on the classes in measuring the coupling of object-oriented systems. And, it evaluates them using the coupling properties suggested by Briand while it compares them with other coupling measures by applying them to a system developed in the language of C++programming language.
