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.

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.

The three main steams flowing through Taejon have some serious problems to be solved or improved. They are : First, the uniform cross section of the rivers should be changed. Second, the extension of the riverside road should be reconsidered. Third. the neighborhood parks on the flood plain should be modified. Fourth, the flood plain parking place must not be constructed. Fifth, the ecosystem will be destroyed by the structure constructed along the rivers. In this study, we suggest that the investment and research on the development of the new technology for the setting the rivers in natural condition should be needed now and the continuous investigation and long-term plan to preserve the ecosystem of the rivers should be required. The environmental conditions of Taejon-stream, Yudung-stream and Kap-stream are indicators of the standard of living of the citizens in Taejon. Now is the time to reconsider the careless construction around the rivers and to prepare the long-term plan for the protection of the ecosystem and natural environment.

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㎜.

This study is to investigate the researches with handball game by research domain and methodological aspects during its 10years (1990-2000). As results of analyzing methodological structure, characteristics of subjects by research domain and the number of articles statistical techinics by years. 1. the researches of handball games need longitudinal study with academic arena in accordance with the globalization trends. 2. The number of case and representative is to provide academic suport therefore it is nesessary to provide effect size for handball games for identify susficious questions sample sizes for students and professors in the field of measurement & evaluation 3. It is proud to acculately need to test methodological research domains in order for performing handball related researches journal to be acknowledged by scholars in other parts of the world. the focus must be on equality rather than on quantity.

An experimental investigation was conducted to investigate the strength and deformation capacity of Wide Flange Steel Encased Reinforced Concrete(SRC) Columns subjected to constant axial compression and cyclic lateral loading conditions. Six one-third scale specimens were tested, each consisting of a structural steel size encased in reinforced concrete. The parameters studied in the test program included the effects of B/t ratios of encased steel(=13, 18, 23), ratios of axial force(=1/3, 1/6). As a result, capacity prediction based on superimposing the moment-axial-load interaction surfaces of the steel shape and reinforced concrete produced good results; the average of the experimental-to-predicted capacity ratio being equal to 0.99∼1.20. The observed hysteretic behavior of the test specimens indicated that adequated ductility can be achieved and the concrete core must be inhibited to buckling of wide flange.

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.

CDMA 시스템에서는 이동국이 Open-loop 전력제어 및 Close-Loop 전력제어를 할 때 비 선형적인 AGC의 특성으로 인해 수신기의 감도가 현저히 낮아진다. 본 논문에서는 AGC의 비선형적인 특성 곡선값을 S/W로 선형화 시켜 RAS RAMDATA를 생성하고 이를 RAS RAM에 넣어 선형적으로 보상된 AGC특성을 얻는 알고리즘을 제안하였다. 그리고 실험을 통하여 그 유효성을 증명한다. In CDMA system, the sensitivity of receivers is lowered significantly due to characteristics of non-linear AGC when the mobile station implements open-loop power control and closed-loop power control. In this paper, We propose a algorithm that obtains linearly conpensated AGC characteristic by inserting the RAS RAM DATA in RAS RAM, which linearizes the value of non-linear characteristic graph in AGC by S/W, and the experimental results shows the validity.

In handball games, There is a close correlation between the results of games and how defense pattern are effectively changed following the attacks of the opposite following game times. That is, effective attack pattern have important effects on the results of games. This study is examines of the differences in the results of games following defense strategies which greatly influence on the opposite team in handball games. For the study, games of men's professional teams were photographed. Test was executed to examine the frequencies of the pattern and positions bringing marks obtained by the opposite team, which were done by goal keepers, following various defense type of each team and following defense pattern. ANOVA was executed for the pattern and positions bringing marks obtained by the opposite, which were done by goal keepers. In addition, forms and positions bringing marks were obtained by the opposite, which were done by defences, following various defense positions. When there was a difference between team levels, post tests were done and here are the results: 1. Defense abilities in handball games are diverse, following attack pattern, and they are connected directly with game ability. Therefore, defense abilities cannot be neglected. This study shows that according to the levels of games, such as advanced, intermediate, and beginner, defense pattern are different in each team, having various effects on game ability. Thus, developments of various strategies appropriate for teams' characteristics have great influences on game ability. 2. Defense pattern following times are connected directly with the progress of game. The analysis result of defense pattern following times shows that each team keeps fixed defense patterns appropriate for its characteristics. However, the need of a post study is suggested since defense pattern are a little different according to the characteristics of the opposite team on the field.
