The purpose of this research was to find out the effects of the person and costume on the formation of first impression. 4 Models were choosen who had sporty, intellectual, social and cute impression. Tried on them sporty, intellectual, social and cute costumes, 16 pictures of them were taken four by four method, and those were shown to 640 college girl students in Seoul to check the change of impression. The results are as follows: 1) The sporty costume to be perceived as sporty than either the social or intellectual and cute costume. 2) The social person to be perceived as social than either the sporty on intellectual and cute person. 3) The intellectual costume to be perceived as intellectual than either the sporty or social & cute costume. 4) The cute costume to be perceived as cute than either the sporty or social and intellectual costume.

The purpose of the study is to make experimental whether three-dimensional body (especially face) has illusion based on theoretical background of form dimensions and color bright among precedent multi-form illusion, using the function of computer simulation. To investigate illusion that factors of clothing design(line, color, material) effect face, as the following is tried to solve giving change to neckline, collar, scarf which is believed to influence near face. How to make experiment as follows watching in order 13 scenes of a pair of with basic design and experiment design. Then the data were subjected to analysis of variance and Dunan's multiple range test. The result of this studying as follows, l. Face looks larger in complex neckline than simple neckline. The larger collar is the larger face looks. 2. In white jacket, illusion(the lower luminosity of scarf color gets, the brighter face brightness gets) is shown. In black jacket, also illusion(the higher luminosity of scarf color gets, the darker face brightness gets) is shown. 3. In experiment on hardness and softness of face impression according to the material of collar, collar of knit and fur gives us assimilation illusion bring softer impression of face.

Transmission scattered ray of ??-ray classified by Pb thickness was as follows: 1. This study explored the transmission scattered ray classified by Pb shield thickness using Electrometer. GM survey meter and Pocket dosimeter. It was shown that the scattered ray content in transmitted ray decreased for the following two cases : as the thickness of Pb shield increased. and the distance between ??-ray source and Pb shield increased. However, in case of GM survey meter, when the distance between central source and detector was vertical, the thickness of Pb shield did not have a significant relationship with scattered ray content in transmitted ray. 2. The ??-ray dose change classified by lateral distance between central ray and detector was compared. For electrometer, when the distance between ??-ray source and Pb shield was 27.5cm, the scattered ray content in transmitted ray increased. In this case, lateral distances were 5cm and 10cm. Additionally, as lateral distance increased when the distances between ??-ray source and Pb shield were 17.5cm and 37.5cm. So did the scattered ray content in transmitted ray. In case of pocket dosimeter and GM survey meter, as the distance between ??-ray source and the detector went up and a ??-ray sources and Pb shield increased, ??-ray dose decreased. 3. Absorption rate of ??-ray by Pb shield a showed a peak value when the Pb thickness was 5.6mm. In addition, as the Pb thickness increased absorption rate went down. 4. The half value layer of Ir-192 was 2.38mm Pb.

This study was carried out to investigate the operating conditions of X-ray units and exposure factor of chest P-A radiography on the 80 medical facilities in Kyong gi do from July 1 in 1999 to January 31 in 2000. As a result of this study, main finding were as follows. 1. The rectification method of the generator were used mainly single phase full wave in 80%, three phase full wave and inverter type in 14%. 2. Maximum ratings of X-ray tubes were 48% at 125 kVp maximum tube voltage and 36% at 150 kVp. The maximum tube current higher than 500mA were shown in 78% of all the examined. 3. In most medical facilities, tube voltage lower than 100 kV was used and 13% of the medical facilities high tube voltage higher than 100kV was used. 4. The exposure time was used lower than 0.05sec in 33% and 83% of all the X-ray units used tube current rangeing form 500 to 800 mA. 5. The added filter was not used in the 81% of all the facilities and used 58% of the grid ratio at 8:1. 6. The orthochromatic system was only used in 17% of screen/film system.

사람 기관지상피세포주인 BEAS-2B에 담배연기농축액(CSC)을 처리하여 유도된 1198 세포주는 대조군 세포주인 1799에 비해 현저하게 낮은 glutathione 농도와 낮은 glutamate-cysteine ligase (GCL), glutathione peroxidase (GPx), glucose-6-phosphate dehydrogenase (G6PD), catalase 효소활성을 보였다. 두 세포주를 포도당 존재 하에서 4시간 hypoxia 처리 후 reoxygenation 하면서 시간에 따른 세포의 항산화계 활성을 측정한 결과, 1799 세포주에서는 의미 있는 변화가 관찰되지 않은 반면, 1198 세포주에서는 hypoxia 처리에 의해 glutathione의 농도 및 GSH/GSSG 비와 G6PD 활성이 감소되었고, reoxygenation 기에는 GPx, glutathione reductase (GRd), G6PD, superoxide dismutase 활성이 감소되었다. 그러나 reoxygenation 2시간 이후에는 GRd와 G6PD 활성의 회복이 관찰되었으며, 그 결과 GSH/GSSG 비율이 회복되었다. 이 실험 결과는 CSC가 능력을 현저히 저하시킬 수 있음을 보여준다. Glutathione은 hypoxia-reoxygenation에 의한 산화적 스트레스 하에서 항산화제로서의 역할뿐 아니라, 세포 내 GSH/GSSG 비의 변화를 통해 산화적 스트레스에 대한 항산화계의 적응 반응 여부를 결정하는 중요한 인자로 작용할 것으로 보여진다.

Recently, the importance of mammography rises with the increase of breast cancer. The purpose of this study was to measure half value layer of energy used for clinic and thickness of the compressed breast with both craniocaudal(CC) and mediolateral oblique(MLO) mammography, and average glandular dose. The subjects were 381 people, whose mediolateral oblique and craniocaudal mammography were taken by certified mammography technologists for fifty days. The women examined were classified into 5 groups according to their age. Besides, we measured air exposure dose to calculate average glandular dose by 4.2㎝ phantom. The results are as follows: 1. Half value layer in each tube voltage(26㎸~32㎸) was 0.334㎜Al~0.403㎜Al. 2. People in 30s, 40s, and 50s occupied 85.83% of the subjects. 3. The average thickness of craniocaudal(CC) mammography was 3.26㎝ while the average thickness of mediolateral oblique(MLO) mammography was 3.43㎝. 4. Air exposure dose depends on thickness, energy, age, and target/filter. But on this study it was measured an anther 300mR~2000mR. 5. The average glandular dose at a breast of 4.2㎝ thickness depended on the tube voltage. In the case of Mo/Mo, it measured 0.722~0.616 mGy which was less than ACR standard 3.0 mGy.

The frequent use of intravenous alimentation as a routine measure in hospitalized patients makes phlebitis one of the most common source of hospital morbidity. This. study was performed to explore the relationship between the incidence of phlebitis_, in continuous intravenous infusions and type of solutions, solution pH, size of needles, sites of infusions and duration of infusions. 181 adult patients admitted to St. Mary's. Hospital were observed for symptoms of phlebitis during four month period from November, 1973 to February, 1974. The results of the study were as follows. 1) Among 181 patients, clinical signs and symptoms of various degrees of phlebitis occured in 59 patients (36.20); slight reaction in 43 patients, moderate reaction in 12 patients and severe reaction in 4 patients. 2) The younger age group of 20 to 40 showed to be particularly susceptible to phle bitis. The age group of 30 to 40 revealed the highest incidence of susceptiblility to this complication. 3) There was 38.9% of incidence of phlebitis from infusion.placed in the dorsum of hand, and 32.9% in the forearm. Smaller veins were more susceptible than. larger veins. 4) -It was considered that there was a close relation between the incidence and the amount and time required for infusion. High incidence of 33.0-44.0% was shown after the infusions which required over 12 hours and relatively lower incidence (24.3%) in the infusions completed within 12 hours. 5) pH level of solutions was considered to be an important factor there was 61.5% of incidence in pH 3.0-3.9, and lower incidence in normal pH. 6) No, difference was found between solutions containing antibiotics and solutions not containing them. According to the results obtained from-the study, the duration of infusion ~ appeares "to be one of the most important variable relating the incidence of phlebitis, and it ;could be better prevented if infusion solutions are neutralized.
