Objectives: This study aims to examine if a garbage dumping site has real and negative influence on the quality of life (QOL) for the nearby residents. The net effects of the residential distance from the garbage dumping site and from the garbage truck route were investigated for five domains of the QOL. Methods: Two hundred fifty seven Shin-dong Myeon residents, Chun-cheon Si, participated in a self-administrated survey. The Shin-dong Myeon garbage dumping site began operating in 1996. ANCOV A with generalized linear models and multiple regression analysis were performed. Results: Descriptive analyses show that a residence nearby a garbage dumping site is negatively associated with the physical and environmental domains of the QOL. The residential distance from the garbage truck route does not exert any significant effect on various domains of QOL, except for the environmental domain. On the multivariate analysis, the residents living near the garbage dumping site tended to have a significantly negative QOL in the physical and environmental domains. However, the distance from the garbage truck route did not show a significant nor substantial effect on the QOL. The demographic and socioeconomic control variables are associated with a number of the QOL domains, and their patterns are consistent with the general expectations. Conclusions: The results indicated that a garbage dumping site is considered to be an environmental hazard among the nearby residents according to the lower scores on the physical and environmental domains of the QOL. The findings from this study provide comprehensive understanding on the residents' QOL, and they may help politicians and policy makers make decisions for appropriate interventions.

The purpose of this paper is presenting helpful materials for direction and advancing skills by analysing motions of back handspring of the gymnasts who represent the province. After photographing back handspring motions of four college gymnasts who took part in the 64th National Athletic Meeting in the series of three-step running pace, round off, back handspring, tucked backward somersault with a movie camera (37 frame/sec), I could get the locus of motions. I compared the motions with ideal motions presented by specialist and get the following conclusion. 1. At the first landing, I found that they landed in a motion leaning forward by about 70°. I think this defect can be corrected through strong snap down practice in round off. 2. At the first landing, they erected their heads in 163°∼197°, and arms came down by 15° from the horizon when landing. I think this is a disadvantage to them in getting speed when the body is bent backward with arm-swing, and this defect can be corrected through the practice of landing with arms attached to ears. 3. At the phase from the first landing to the take-off, when bending the body backward, the head bent backward before swinging the arms. I think this is a disadvantage to them in getting sufficient speed when bending the body backward, and this defect can be corrected through the practice in which arms is attached to the arms intentionally in swinging arms backward. 4. At the phase from the first landing to the take-off, they swung their arms without relaxing the wrist. I think this is a disadvantage to them in bending the body speedily. 5. At the phase from take-off to hand touch, the legs were spread out during the inflight motion. I think this results from the gymnasts' habit of reducing the time which is used in tumbling by shorting their bodies, and this phenomenon happens among trained gymnasts unconsciously, reflectively and frequently. 6. In hand touch, the shoulder line was not cut, which is necessary so that the arms might be vertical against the land. I think this results from not getting sufficient speed in bending the body backward. 7. After the hand touch, the shoulder went forward and legs snaped down a little after the apex. I think this phenomenon happens because the hand off is delayed and the gymnast can't snap down the leg strong.

Ⅲ-Ⅴ족 반도체의 연구 : GaAs의 합성, 단결성 및 특성 Crystal Growth and Characterization of GaAs

Temperature of 618 and 1250℃ at As and Ga sities respectively in the horizontal Bridgman furnace and growht speed of 0.7cm/h were found to be optimal for the production of single crystalline GaAs. Self-seeded and unintentionally doped GaAs crystals showd n-type characteristics with Hall mobillity of ∼0.75㎡/V-sec and carrier density of ∼10^19 m^-3 when the mesurements were made right after the growth. About three month later it was found that the same samples were converted to p-type GaAs. The analysis on the p-type sample showed that impurity scattering is dominant at around room temperature and thus the measured Hall mobility was 0.0065㎡/V-sec at 300K. 7.4±0.6 eV was obtained for acoustic deformation potential in the heavy hole band by fitting the theoretical conductivity and Hall coefficient to the corresponding experimental data. The value is very much higher than the theoretically estimated value, 3.6eV. The carrier density variation with temperature obtained from the present analysis gave 0.38 and 0.17 eV respectively for the activation energies of donor and acceptor.

Experiments were performed for the real sized 13 reinforced concrete columns of 350×350×3360㎜ with normal and high strength concrete in order to observe the fire-damaged residual strength of these columns. Columns were heated according to the ISO heating curve. Main experimental parameters were: magnitude of axial load, heating time, cover thickness, and eccentricity. Effects of these parameters were experimentally quantified. Although significant reduction in residual strength was observed for the columns exposed to longer heating time, little effects on the residual strength by cover thickness and magnitude of axial load were observed. Repairing did not lead to the improvement of residual strength. Strengthening by wrapping the GFRP sheets, however, recovered the fire-damaged column strength up to 97% of axial strength of the prototype undamaged column.

Fire-damaged structural behavior of high strength reinforced concrete columns mostly depends on duration of heating time, geometrical shape of a section, constituent material properties, loading conditions and moisture content. Unlike beam element, all boundaries of a column suffer from heat-induced damages and this requires real-size experiments be conducted in order for accurate assess of the fire-damaged structural behavior of columns. Ten real-sized high strength concrete columns with different parameters are exposed to fire for three different time intervals in this research. Observations are made for the effect of these parameters on the degree of spalling, axial expansion and contraction, member buckling, failure based on ISO standard in addition to data of heat propagation in a section during the heating.

This paper is a descriptive study that inquires about stress and self-esteem of obese children to lend assistance about understanding emotional care as weight management of children. The data collection was given by the structured questionnaire during five days, from 5th to 10th on march in 2003 at one primary school located in K-city. The subjects were 286 children in 11-12 year old children. The instruments used for this study were an Obesity-Stress Scale(Cho Yang Rae, 1997) and a self-esteem questionnaire including Self-Perception Profile(Harter, 1982). Data were analyzed with frequency, percentages, x²-test, ANOVA, Pearson correlation using the SPSS program. The results were as follows; 1. A stress of obese children was the highest among three group, which was significant of statistical data. On the other hand, self-esteem do be shown the same as the above but was not significant statistically. 2. A relation between stress and self-esteem of obese children was shown to be in inverse proportion ratio so that the higher stress was the lower self-esteem. 3. To research the differences of the stress followed by the general characteristics of children, there are meaningful differences in sex, character, factor of stress, shape of father's body and shape of mother's body. 4. To research the differences of the self-esteem followed by the general character of children, there are meaningful differences in sex, character, shape of mother's body and socioeconomic status.

In this study, we made investigation into water permeation, solute separation, concentration and Na^(+), K^(+), Mg^(2+), Ca^(2+), Cl^(-), SO^(2)_(4)-, HCO^(-)_(3) ions separation of seawater by the revers osmosis process using a suitable semipermeable membrane. The different thickness of membranes were prepared. On heat treatment, temperature was 80℃ and thier effects were also investigated. The flat single module system was made to be capable of treating feed solution at 200-2000cc/min and 120 atm. The experimental results can be summerized as follows: 1) As the effective operating pressure increased, permeability of pure water proportionally increased. 2) As the exposure period of the manufactured membrane in air increased, permeation rate increased, but as the thickness of the membrane increased, permeation rate decreased. 3) The capacity for being reproductive of the manufactured membrane (CA: 30wt%, Formamide: 45wt%, Acetone: 25wt%) in their performance was less than 10-30% and agreed with that reported in the literature. 4) We could separated about 85-95% of salt ion in seawater using a flat single module system.
