Indian multivoltine mulberry silkworm (Bombyx mori L.) strains are poor in silk productivity and fibre quality. However, they are commercially exploited for the past five decades either in the form of pure breeds or cross breeds because of their adaptability to adverse climatic condition and acclimatization to specific regions and seasons. In the present paper conservation strategies of multivoltine silkworm genetic resources are dealt along with detailed information on accessibility of genetic resources, method of genetic resources conservation, characterization of genetic resources for morphological and productivity traits of economic importance. Selection of best ten accessions based on various economic parameters including yarn quality and their scope for future utilization are discussed.

Several kinds of medical materials are supplied and returned or disposed everyday in hospitals. And so, the transportation system has to be planned according to their circulation. This study aimed at clarifying the relation between the stock area in ward and the departments in which the contaminated materials are disposed or recleaned and the utilization of vertical transportation system with regard to contaminated materials. The results are as follows : 1)The stock area/rooms for contaminated materials are dipersed according to their kinds. Several department have relation with the area/rooms in ward. 2)The vertical transportation system for contaminated materials are not reserved and utilized independently in hospitals surveyed. And so, cross contamination can easily occur. Therefore, independent transportation system is required and utilized only for them.

Thirty-six heifers of three different breeds were fed rice straw, either upgraded with 4% urea, or supplemented with 2% urea, sprayed on the straw just prior to feeding. The effects on liveweight gain and dry matter intake were measured for pure Sahiwal heifers, Sahiwal ${\times}$ local crosses and Jersey ${\times}$ local crosses. Urea upgraded straw gave better growth than urea supplemented straw, average 217 g/day/ animal versus 71 g/day/animal. This was associated with a higher intake of upgraded straw, compared to supplementation straw (2.4 versus 1.8 kg/100 kg BW). No overall breed effect on growth was found (P>0.05).

A fuzzy controller is designed for compensating the cross-coupling effect of induced roll due to the dynamic characteristics of three fin torpedo. Since the utilization of fuzzy-coprocessor has many interfacing problems with typical microprocessors of the guidance and control unit, the simplified fuzzy inference method based on nonfuzzy-processor is proposed to implement fuzzy controllers of three fin torpedo. This method provides a flexible rule-base design to guarantee the robust control. The good potential of the proposed design is shown through real-time simulations using both a mathematical model on AD-100 computer and an implemented controller on Intel 80C186/80C 187 microprocessors employing 12bit A/D converter.

Waste tires are a significant problem with the increasing in number of automobiles. Therefore, many researches have been studied on this field. Recycling is the one of the popular method aspect to environmental and economical in the treatment methods of the waste tire, which loads that the reuse of scrap tire rubber has been a challenge in the past. However, it is not easy method to melt down and mold into new products because the in rubber is a cross-linked polymer. Most difficulty in recycling is the recycled product is not economic. Therefore, the goal of this study is to develop the high valuable products for reused waste tires. In this paper, we try to make an economic recycled technology using scrapped waste tires. This technology may applied for manufacturing the end products such as a rubber block and a ballast mat for high-speed train.

In the forthcoming public ATM/B-ISDN, the efficient resource management with pre-planned transit networking which public domain NNI signaling is essential to maintain high network utilization and to assure QoS to the multimedia service users. For this purpose the transit networks must be managed according to the bearer service capability which is defined by ATM Forum and ITU-T. In this paper, we introduce an implementation of ATM transit networking with ATM VP-XC(Virtual Path cross-connect) and US(Network Management System). The functions of ATM VP-XC and NMS have been simulated with OPNET 6.1 modules. We implemented the F4 OAM functions of ATM VP connection according to the ITU-T 1.610 recommendation. Also, the ATM VP transit networking is managed by the NMS according to the connection management architecture of the TWN(Telecommunications Management Network) /TINA ( Telecommunications Information Networking Architecture).

Mammography utilization is low in Iran compared with other countries. Here a cross-sectional survey design was used to investigate psycho-social and individual factors associated with mammography among 400 women asymptomatic of breast cancer. The study was carried out at the four outpatient clinics of Tehran during the period from July through October, 2009. We found that mammography screening was related to higher self-efficacy and women's occupation. Future tailored interventions on potential psycho-social determinants and specific demographic factors are critical in increasing mammography screening rates among Iranian women.

This paper deals with a novel utilization method of the predicted current in the high performance PI current controller with a control time delay. The inevitable error of the predicted current in the linear servo drive using a permanent magnet linear synchronous motor is analyzed and a modified cross-coupling decoupling synchronous frame PI current controller is proposed in order to improve the current control response under the control time delay. Simulation and experimental results show that the proposed current controller has an improved current control performance under both the electrical uncertainties of a servo drive system and the control time delay.

Changes in quality of cooked rice after microwave reheating were evaluated. Ceramic coated microwave oven reduced a reheating time(1 min). Storage temperature, storage time and microwave reheating did not affect the color value of cooked rice after microwave reheating. Hardness of cooked rice after microwave reheating decreased in frozen storage treatment. Photomicrographs of cross-section of cooked rice after microwave reheating showed restoration of starch. Effect of storage temperature and time were not significant in appearance, aroma, taste and texture of cooked rice after microwave reheating for sensory evaluation test.

Many kind tree species are growing in Korea. However most of them are inferior in wood qualities and production for commercial utilization except several species. Among the useful several species Red Pine (Pinus densiflora S. et. Z.) is growing in main tree species and most generally utilizing wood in korean forest. It is used widely as mine timbers, cross ties, boxes, floorings, pulpwoods, constructions and engineerings. Although this species is most useful and economical in this country, the basical properties on relation between wood and relative humidities were not studied certainly. This study was performed by need of inspection the hygroscopic and swelling properties to be apllied for physical manufacturing. According to the results the Equilibrium Moisture Contents of each relative humidity conditions are as table (3), and the swelling values of sap and heartwood are as table (4) and (5) in text. In this study sapwood moisture contents are higher than heartwood in each relative humidities conditions. Tangential and radial ratios of average swelling values are 1:1.971 in sapwood and 1:2.178 in heartwood.
