Recent trends, the major objective of this investigation was to examine the effect on judo players achievement goal orientation of middle and high school on attribution styles. Subjects were 107 judo players in the middle and high school. Tools were used to TEOSQ and attribution scale. Results revealed that when they perceived task as success, task-and ego-directed goal orientation had significant effect on effort and ability respectively. This results were discussed in terms of the three-dimensional achievement goal orientation, earned helplessness, and implicit theory of Dweck(1988) as future studies.

This study was conducted to investigate the changes of physico-chemical properties of soil applied with compost made by food wastes and its effect on the growth and yield of Chinese cabbage. Chinese cabbage was grown in the soil treated with food waste compst(FWC) of 0, 0.625, 1.25, 2.5, 5 and 10㎏/3.3㎡. As the amount of FWC increased, number of leaves, leaf area and fresh weight increased where application of 5㎏ and 10㎏/3.3㎡ showed vigorous plant growth in the late growing period. The pH of soil by application of FWC was not raised, which was similar to the soil before treatment. Organic matter increased in soil by increasing the amount of FWC. However, concentration of Cu and Pb in the soil reduced. The concentration of available phosphate(P) was lower in the soil treated with FWC than in the soil before treatment, which means that a large amount of P may be uptaken by plant. This study suggested that FWC should be an alternative to chemical fertilizer for vegetable production.

The WE DSP32 in AT&T's second-generation programmable digital signal processor with 32-bit floating point arithmetic. This device can be used in a wide varity of complex digital signal processing algorithms such as speech recognition,high speed modems, low-bit rate voice coders, and multichannel signaling system. This paper reviews the LPC analysis and synthesis of speech signal and presents a real time implementation methodology of these algorithms using the WE DSP32. For efficient data handling, circular buffer is proposed. The implementation results show that deep pipelining characteristics of the processor should be fully utilized to satisfy the timing constraints,

In this study, we discussed littroal movement and sedimentation of Keum-river estuary and estmated of deposition capacity. Keum-river estuary sea wall was constructed in 1988 Jan. and the sluice gate was completely closed in 1995 May. At the present, Kun-Jang new port. South and North jetty, Semankume sea wall and Kun-Jang industry estate are developing the Kume-river estuary around. At this developing and construction of Keum-river estaury, in many element of hydrauli - ocean waves, tide, tidal prism and depth of water - have changed. Tide analysis used statistics-analysis and harmonic-analysis from 1984 to 1997. Depth of water analysis used bathymetric chart from 1985 to 1997. Therefore we must correctly decise hydraulic element that is use simulation numerical test and hydraulic model. We analyze ocean waves, tide, tidal prism and depth of water change and modeling bed-load movement simulation; K-Cytengel, suspending-load deposition simulation; DIMOS-IV. Through the K-Cytengel and DIMOS-IV simulation estemated the sedimentation capacity and propose suitable answering such as dredging, water injection and remove of estuary sea wall.

Autonomous objects have capabilities of navigating through the underlying network and performing various tasks at each node. By these powerful capabilities they can be applied to several distributed application areas. Tn this paper, we propose a method for on-line maintenance of distributed software systems by using autonomous objects. In our method, multi-version computation techniques are applied. We think it is very feasible for on-line distributed software maintenance.

Ultrasonic testing of a reinforced concrete member by means of the ultrasonic testing apparatus is affected by the steel bar embedded in concrete. A test location avoid the zone of steel effect when selecting test location in reinforced concrete member. But if it is impossible, it is necessary to make a correction to the measured value to provide an estimate of the velocity of the pulse in the plain concrete. The purpose of this study is to analyze the effect of steel bar on ultrasonic pulse velocity and the evaluate optimum correction formular by means of comparison between pulse velocity in concrete and effective pulse velocity according to steel bar diameters. Concrete mixes having water cement ratio of 0.4 and 0.6 by weight and slump values of 18㎝ in fresh concrete were used to make 20×30×60㎝ cubes for pulse velocity in concrete and effective pulse velocity. The diameters of the plain bars were 6, 9, 12, 19, 25, 32, 38 and 50㎜.

Unsteady-state temperature distributions and thermal deformations of the spindle of a high precision lathe are studied in this paper. Three dimensional model is built for analysis, and the amount of heat generation of bearing and the thermal characteristic values including heat transfer coefficient are estimated. Temperature distributions and thermal deformations of a model are analyzed using the finite element method and the thermal boundary values. Numerical results are compared with the measured data. The results show that the thermal deformations and the temperature distributions of the spindle of a high precision lathe can be reasonably estimated using the three dimensional model and the finite element method.
