Objectives : The purpose of this study was to test the reliability and validity of the Korean translation of Gambling Symptom Rating Scale (KG-SAS). Methods : Using self-report sampling, we eventually included 231 subjects and analysed 70 subjects. These subjects were tested for KG-SAS and the Korean version of Barratt Impulsiveness Scale (BIS). Results : In the reliability test, Cronbach's alpha coefficient was .913 which provided the evidence for the internal consistency. Content validity was assessed with factor analysis and two factors were extracted. Compared with the original scale, both scales embody the same theoretical conceptualization. To assess the validity of the KG-SAS, correlation coefficient was calculated between the KG-SAS and the Korean version of BIS. We got the result that there was a correlation between the KG-SAS and the Korean version of BIS (p<0.01). Conclusion : The results of the present study support that the KG-SAS is a reliable and valid scale for evaluating Pathological gambling symptom assessment. Based on the results, this study suggests that KG-SAS would be a promising measurement to treat and study pathological gambling.

The purposes of this study were to evaluate the effect of adhesive property on microtensile bond strength and to determine the failure mode. Flat occlusal dentin surfaces were prepared using low-speed diamond saw. The dentin was etched with 37% phosphoric acid. The following adhesives were applied to the etched dentin to manufacturer's directions: Scotchbond Multi-Purpose in group SM, Prime&Bond NT in group NT, Scotchbond Multi-Purpose followed by Tetric-flow in group TR. After adhesive application, a cylinder of resin-based composite was built up on the occlusal surface. Each tooth was sectioned vertically to obtain the 1 × 1㎟ "sticks". Microtensile bond strength were determined. Each specimen was observed under stereomicroscope and scanning electron microscope (SEM) to examine the failure mode. Data were analyzed using one way ANOVA. The results of this study were as follows; 1. The microtensile bond strength value were; group SM (18.98±3.0lMPa), group NT (16.01±4.82MPa) and group TR (17.56±3.22MPa). No significant statistical differences were observed among the groups (P〉0.05). 2. Most of specimens showed mixed failure. In group TR, there was a higher number of specimens showing areas of cohesive failure in resin.

김현수,이승무,박진원 연세대학교 산업기술연구소 1985 논문집 Vol.17 No.1

This study was carried out to study the efficiency of the induced aerator which causes nearly complete mixing and high oxygen-transfer in the aerator. With varying rpm, the oxygen-transfer coefficient was determined. The removal efficiency of substrate was measured analytically by varying feed concentration, feed flow rate, and rpm at constant biomass recycle ratio. The experimental results show that the oxygen-transfer coefficient varies linearly with rpm, and the optimum rpm is 3000. By expressing the specific substrate utilization rate constant, K with regard to rpm, the rate constant, K was investigated with varying dilution rate. The DO concentration, the removal of COD and BOD?, and the effect of MLSS in the aerator was also investigated with varying rpm.

전이온도가 72K인 고온초전도체 Y?P?B?Cu?O?에서 초전도성을 감소시키는 Pr원소자리에 Ca과 Zn를 적당히 치환시켜 자기적 성질을 연구하였다. 초전도 전이온도(Tc)는 Ca이 치환된 시료의 경우 80~85k의 범위에서 측정되었으며, Zn가 치환된 경우에는 35~49K의 값을 보였다. 비저항의 온도 변화로부터 결정된 전기적 전이온도는 온도에 대한 자기모우먼트으 변화에서 구한 자기적 전이온도와 비슷한 값을 보였다. 자기이력곡선으로부터 Bean의 모델을 이용하여 Hcl(저임계자기장), Hc?(고임계자기장), 반자성정도, 임계전류밀도를 측정하였다. 이러한 성질들은 시료 내에 Ca의 치환량이 많아질수록 증가하였으며, Zn가 많아질수록 급격히 감소하였다. 특히 임계전류밀도는 x=0.0인 시료는 1.60x10?A/㎠이었으며 Ca이 치환된 시료는 1.30~1.98x10? A/㎠, Zn가 첨가된 시료는 3.5x10?~1.3x10?A/㎠의 값으로 계산되었다. 이것은 시료 내에서 Ca은 초전도성을 증가시키고, Zn는 초전도성을 감소시키는 것을 의미한다. We have studied magnetic properties as a appropriate substitute of Ca and Zn element for Prelement which reduces superconducting properties in the high-temperature superconductor Y?Pr?Ba?Cu?O? of transition temperature 72K. When Ca is put into, the critical temperature(Tc)showed the value of measurement at the range of 80~85K while for Zn the Tc had the range of 35~49K. The electric critical temperature determined by the temperature dependence of resistivity had a similar data to the magnetic field), Hc?(high critical magnetic field), diamagnetic ratio and critical current density have observed by Bean's model from the magnetic hysterisis curve. These properties were increased with adding Ca and abruptly decreased with adding Zn in the samples. Especially, the critical current density of x=0.0 sample was calculated at 1.60x10?A/㎠ and those of the other Ca-added samples at the range of 1.30~1.98xA/㎠and those of Zn-added samples at the range of 3.50x10?~1.30x10?A/㎠. These mean that Ca increases supercondecting properties in the sample and Zn element decreases them.

TMA clathrate that is used as PCM of low temperature thermal storage system in this research creates hydrate crystallization at higher temperature than pure water, and its application is expected as PCM because of comparatively big latent heat without phase separation phenomenon. Ethylene Glycol is used as additive and evaluated experimentally for the purpose of the improvement in subcooling of TMA clathrate. In view of the results so far achieved subcooling is improved, the running time of the refrigerator is reduced. Thus the results are expected to use for the increase of coefficient of performance of low temperature thermal storage system in the building.

To improve the therapeutic method for mastitis, treatment effect of chitosan pharmacopuncture was examined in three milking goats(A,B and C). Mastitis was artificially induced in two milking goats(A and B) and one goat(C) was naturally infected case with mastitis. The acupoint used was Yang-Ming and chitosan suspensions(provided from Tottory University, Japan: 30㎎ of chitosan/㎖)were injected to the acupoint with 5㎖/time for 3 days, respectively. As for the change of somatic cells in milk along with chitosan pharmacopuncture, they showed a decreasing tendency after increase on the 3rd day in all udders of B. In addition, as for the change of total leukocyte counts of peripheral blood with chitosan pharmacopuncture, they showed a decreasing tendency after increase on the 3rd day in B and C except A which showed a increasing tendency until on the 7th day. In the change of neutrophil/lymphocyte(N/L) ratio, increasing tendency was seen in A and C but increasing tendency after slight decrease was observed in B. Further, in the change of serum total protein and A/G ratio, serum total protein content was decreased after slightly increase on the 3rd day in A, and they were decreased after increase until on the 7th day in B and C, respectively. As for the change of A/G ratio, different pattern increasing tendency was shown in A, B and C.

One of the ways to reduce abroad dependence for energy is to utilize solar energy when we are now confronted with not only insufficiency of natural resources but also the serious problems of environmental pollution. Therefore, full attention must now be paid to the development of solar energy system as alternative energy. To achieve this, solar hot water supply system was established at Chosun university, Gwang-ju, and experimental data were obtained based on meterological data and solar radiation. This study has been used the monthly mean values of the daily measurements obtained by data acquisition software Labview. This study shows Gwang-ju is a good region for the utilization of solar energy.
