The aim of this study is to figure out how people recognize the Image of house. The research is based on the approach of cognitive-psychology, which tries to understand the response of human beings toward their environment in term of psychological mechanism. The outcomes from this study are as follows. First, as the result of the factor analysis for the 12 perceptual scales, 3 major factors were extracted. These 3 factors are proved to be the dimension of esthetics and the dimension of ornament, and the dimension of modern. Second, the exterior form of house could be classified into 8 patterns by the 3 dimensions of the perceptual image. Third, the co-relationship between the conceptual and taste images that the exterior form of house has shown in this research, it was found that most respondents more tend to line in the house-looking building than in the non house-looking building. Fourth, it was found that people have more familiar and comfortable Image to simple designed house with hipped roof. This trend has shown to be one of common tendencies that people may have when they think of the image of house. In addition, roof has played the most important role in putting the image of house into people it was found that the most favorite house to the respondents has the esthetic and modern images that the roof shape is not seen in outside and the exterior wall is mainly emphasized. Fifth, the most ideal image of house seems to be sensually beautiful, and not flamboyantly decorated. In addition, it needs to cause the feeling of house-looking and comfort from people and then non-ideal image of house doesn't have any esthetical aspect. Rather, it has idiosyncratic image in general.

Ozone was first used to disinfect water supplies in France in the early 1900s. Its use increased and eventually spread into several Western European countries. Today nearly 1,000 ozone disinfection installations exist (primarily in Europe), almost entirely for treating water supplies. A common use for ozone at these installations is to control taste-producing, odor-producing and color-producing agents. Ozone can also be used in wastewater treatment for odor control and in advanced wastewater treatment for the removal of soluble refractory organics, in lieu of the carbon-adsorption process. Ozone is also very effective virucide and is generally believed to be more effective than chlorine. Ozonation does not produce dissolved solids and is not affected by the ammonium ion or pH influent to the process. For these reasons, ozonation is considered a alternative to either chlorination of hypochlorination, especially where dechlorination may be required.

The adsorption equilibria of methane and ethane in a slit pore model of activated carbon were studied by using Monte Carlo method. In potential caculation. the fluid-fluid interactions are described using the "12-6" Lennard-Jones potential function. and fluid-pore surface interactions are described using the "10-4-3" potential function proposed by Steele. It showed that the pore size distributions effected isotherms from the simulation results in pure component adsorption of methane and ethane at 1∼30 bar pressure. Also adsorbed moleculars could identified occuping location and density from density profiles and snapshots.

두 종류의 ZnSe 분말을 사용하여 sublimation 방법으로 성장한 ZnSe 단결정(as grown)에 대하여 TSC와 TSL을 동시 측정하였으며, PL과 DLTS를 측정하였다. PL 측정으로 I_1, I_2와 DAP 발광을 관측하였으며 DLTS에 의한 깊은준위를 관측하였다. TSL과 TSC의 동시 측정으로부터 얻은 그로우 곡선을 점근 해법으로 분해하여 세개의 준위를 얻었으며 그들의 활성화에너지값은 0.22 eV, 0.30 eV, 0.39 eV이었다. PL spectrum과 열자극 완화과정의 동시 측정 결과로부터 0.22 eV 근방에 impurity에 의한 주게준위와 native defect에 의한 받게준위가 각각 전도대의 아래와 가전자대의 위에 존재하는 것으로 판명되었다. DLTS 측정과 동시측정 결과로부터 0.30 eV와 0.39 eV의 준위는 V_se vacancy와 관련되는 주게 준위임을 알았다. Simultaneous measurements of TSL were carried out on ZnSe single crystals grown by high pressure Bridgman technique and the PL and DLTS signals were observed. Photoluminescence spectrum at 10 K on the ZnSe crystal reveals I_1 and I_2 lines, as well as DAP emission line. DLTS spectrum on the ZnSe crystal show electron trap at 0.33 eV. Two TSC and TSL peaks were observed near 215 K and 230 K, which are identified as having originated from two donor trap levels at 0.30 eV and 0.39 eV, respectively, below the bottom of the conduction band. We also observed single TSL and TSC peaks at 150 K which were identified as having originated from a donor and acceptor trap levels at about 0.22 eV below the conduction band and over the top of the valence band, respectively.

The purpose of this study was to investigate the students' consciousness against noise around nine high schools in Taegu City. It was carried out to make up and analyze a question of noise. The results are summarized as follows : 1. Two schools whose Leq was below 50㏈(A) showed comparatively little noise pollution from noise measurement of schools. Four schools, though their Leq was a little more than 50㏈(A), were supposed to have little complaint about noise because their TNI value was less than 50. Three schools was estimated to have extreme discontentment about noise because their Leq was more than 60㏈(A), so exceeded environmental standard value(50㏈(A)) and their TNI exceeded 70. 2. In questionaire, 61.2% of respondents answered that noise around school was very severe. The main sources of noise were street traffic(45.7%). In season the noise of summer was most severe(81.0%) The responsibility of noise was given to school(21.0%) and community(30.1%). The questionaire showed that damage to study was 56.2% in class, 24.8% in examination. The response to noise during class showed that most students studied bearing noise but 12.3% students gave up studying. About physical damage, 10% students answered 'a little severe' or 'severe', so physical damage was not serious. About mental damage, 30% students-answered 'a little severe' or 'severe', so three times large as the physical damage. As the result, today noise around school in Daegu cause great damage to students in school life, especially study and its psychological effect. Therefore, to live in a good sound environment the study of counterplans to noise around school must be continued.

We investigated characteristics of bacterial infection and antimicrobial suscerptibility patterns of clinical specimens in Dong Guk University Kyong Ju Hospital from october 1991 to december 1992. The types of clinical specimens requested for culture were as follows ; pus(34.2%), urine(29.6%), sputum(25.2%), blood(9.2%), etc. The most frequently isolated organisms were E. coli(17.6%), Pseudomonas(12.7%), S. aureus(12.2%), and CNS(11.2%), orderly. Predominant organisms from pus, urine and sputum were S.aureus, E. coli and Pseudomonas. Blood culture was requested 1,244 samples from 614 patients, 91 pathogeni organisms were isolated(14.8% from patient and 7.3% from requested clinical samples). E. coli was most frequently isolated(29.7%) and Salmonella typhi was noted 8.8% from the requested samples. The patterns of isolated organisms according to departments were as follows ; E.coli and Klebsiella were frequently isolated in internal medicine and general surgery, E.coli and Pseudomas in Neurosurgery, S. aureus and Pseudomonas in orthopedic surgery. In ICU, Pseudomonas was predominatly isolated and the rate of mixed infection was also high(16.4%). Most of gram-negative bacilli revealed relatively high susceptibility to Chlorampenicol, Amikacin, Tobramycin and Carbenicillin, but Acinetobacter were only susceptible to Carbenicillin and Tetrecyclin, and Serratia were to Carbenicillin and Amikacin while Salmonella were susceptible to all tested first drugs. The proportions of multi-drug resistant bacteria were 34.9% of Acinetobacter, 21.1% of Serratia, 20.0% of Pseudomonas and 15.4% of Citrobacter but Aztreonam was highly susceptible(84∼100%) except Acinetobacter. S. aureus and CNS were susceptible to Chlorampenicol, Oxacillin, Cephalothin and Vancomycin, especially, 100% susceptible to Vancomycin. But Methicillin reistant Staphylococcus aureus were very high(49%) inspite of new constructed hospital. Pneumococcus and Streptococcus species were relatively high susceptible to all tested drugs.

A study has been made of the exchange of Ag^+, Li^+, and Ba^++, Ca^++, Sr^++ ion by using synthetic zeolite-13X and zeolite-NaA. The zeolite used in this work was supplied as beads by Aldrich Chemical Company, Inc., and the formula of unit cell is M_x/n[AlO₂)_x(SiO₂)_y]zH₂O. X-ray diffraction analysis and Fourier transform infrared spectroscopy indicated that the crystallinity of zeolites was retained though sodium ion in zeolite exchanged with the cation. The amount of ion exchanged was measured by the determining of the amount of cation remained in solution by Inductively coupled plasma, and surface area, adsorption isotherm, Ion exchange kinetics. The selectivity of ions was in the order Ag^+>Li^+>Sr^++>Ca^++>Ba^++.

Purpose: A genome-wide association study has identified the 15q25 region as being associated with the risk of chronic obstructive pulmonary disease (COPD) in Caucasians. This study intended as a confirmatory assessment of this association in a Korean population. Methods: The rs6495309C>T polymorphism in the promoter of nicotinic acetylcholine receptor alpha subunit 3 (CHRNA3) gene was investigated in a case-control study that consisted of 406 patients with COPD and 394 healthy control subjects. Results: The rs6495309 CT or TT genotype was associated with a significantly decreased risk of COPD when compared to the rs6495309 CC genotype (adjusted odds ratio=0.69, 95% confidence interval=0.50-0.95, P=0.02). The effect of the rs6495309 C>T on the risk of COPD was more evident in moderate to very severe COPD than in mild COPD under a dominant model for the variant T allele (P-value of test for homogeneity=0.02). Conclusions: We confirmed the association between the 15q25 region and the risk of COPD in a Korean population.

In this study, it was observed that the discharge voltage is increased(Vd ∝ H), the discharge current and luminous intensity are decreased(L ∝ H^2) as the magnetic field intensity(H) applied on the several commercial fluorescent lamps is increased. Magnetic insulation is appeared in the condition that critical transverse magnetic field is applied on the fluorescent lamps. At that condition, discharge current is reduced very low level, and then glow is disappeared. As the length of the lamp tubes is decreased, magnetic field intensity has to increased in order to occur "magnetic insulation". The experimental relation between critical magnetic field intensity for magnetic insulation anil the length of the lamp tubes (H^*d_eff/V_d^(1/2) = A) is obtained.
