We prepared a highly sensitive hydrogen (H2) sensor based on Indium oxides (In2O3) porous nanoparticles (NPs) loaded with Platinum (Pt) nanoparticle in the range of 1.6~5.7 at.%. In2O3 NPs were fabricated by microwave irradiation method, and decorations of Pt nanoparticles were performed by electroless plating on In2O3 NPs. Crystal structures, morphologies, and chemical information on Pt-loaded In2O3 NPs were characterized by grazing-incident X-ray diffraction, field-emission scanning electron microscopy, energy-dispersive X-ray spectroscopy, respectively. The effect of the Pt nanoparticles on the H2-sensing performance of In2O3 NPs was investigated over a low concentration range of 5 ppm of H2 at 150–300 °C working temperatures. The results showed that the H2 response greatly increased with decreasing sensing temperature. The H2 response of Pt loaded porous In2O3 NPs is higher than that of pristine In2O3 NPs. H2 gas selectivity and high sensitivity was explained by the extension of the electron depletion layer and catalytic effect. Pt loaded porous In2O3 NPs sensor can be a robust manner for achieving enhanced gas selectivity and sensitivity for the detection of H2.

사무소건물의 개보수에 따른 실내환경의 거주후 평가 연구

윤성도,김종진,손장열 대한건축학회 2006 대한건축학회논문집 Vol.22 No.3

This study evaluates the office environment satisfaction from the questionnaire and the improvement effects for the remodeled office building which is built for 26 years ago and located in Seoul, Korea. The questionnaire is carried out three times; August 2002 (Summer, before remodeling), December 2002 (Summer, after remodeling), and July 2003 (Winter, after remodeling). The questionnaire for office occupant includes general consideration, sensation of indoor environment, satisfaction of indoor and outdoor space, sensation of working environment, experience of illness and allergy, and response to sick building syndrome. The results of this study is outlined below. 1) Before and after remodeling building the office occupants are questioned about the satisfaction of office environment. It is resulted that indoor environment such as thermal environment, indoor air quality, lighting and noise is improved remarkably. The improvement of storage size and design, and office network system affects the occupant's satisfaction, however, influences a little bit. The improvement effect is small for exterior design and color and outside view. 2) After remodeling the office building the occupants are more satisfied with new working environment, however do not feel the need for reform. Because of the improvement of indoor environment the anxiety of sick building syndrome is decreased a little bit. 3) The sensation of air stream, cold or hot sensation, and thermal sensation felt by human body is improved a little. Moreover, the office occupants are more satisfactory with indoor office environment questioned with air-conditioning, cold or hot sensation, indoor air quality, odor, and noise. It is inferred that HVAC (heating, ventilating, and air-conditioning) systems are operated properly.

During the last 6 years since 1975, epidemiological studies were done on 253 children with tuberculous meningitis admitted in 3 general hospitals in Daegu. The result were as follows; 1) The statistical studies indicated a gradual decrease in the incidence after 1975. Concerning the age difference, the highest incidence was noticed in the group of the children under 3 years old, rate of the group was 57.3% of the total patients. Concerning sex differences, the incidence of the male patients were slightly higher than that of the female patients. Concerning the seasonal differences, its incidence in spring was found to be the highest. Concerning the areas, the incidence in the suburban area was highest and rural, middle urban and central area in the large city were followed. Concerning the birth order, the incidence was higher in last child than in first and middle child. The source of the infection was mainly familial and inicidence of the group with infectious source accounted for 36.5%. The incidence of the group inoculated BCG accounted for 39.1% of the total patients. The main chief complaints were drowsiness, convulsion, vomiting, headache and fever. Main complications of the disease were miliary tuberculosis, 17.0%, pulmonary tuberculosis, 9.5%, other tuberculous lesion, 2.0% and other diseases, 6.0%, respectively. Concerning duration between initial onset and admission within 10 days, 11-20 days and after 20days were 36.8%, 40% and 20.6%, respectively. Concerning duration of treatment were within 5days, 6-10days, 11-20days and more than 30days were 31.0%, 15.0%, 42.0% and 12%, respectively. 2) The prognosis of the diseases was analysed by various factors. Concerning the age difference, the patients less than 3 years old showed low rate of improvement and the rate of improvement increased with increase of ages. Concerning sex difference, the rate of improvement was slightly higher were in male than female cases. Concerning calendar year, the rate of the improvement was increased year by year. Concerning seasonal difference, the rate of the improvement was the highest in summer and autumn, winter and spring in that order. Concerning birth order, the rate of the improvement was highest in middle child and last and first child were in that order. The rate of the improvement were higher in the patients with infectious source than in those without sources and in the group of BCG vaccination than in that of non-vaccination. Concerning relationship between the rate of improvement and the history of infectious source and BCG vaccination, it was found that its rate of the patient with infectious source and BCG vaccination was highest paradoxically and the patient with infectious source and non-vaccination was lowest. Concerning the duration between initial onset and admission, the rate of improvement was higher in shorter period than that of longer period. Concerning the duration of the treatment, the rate of improvement was higher in the patients received longer period than that of shorter period. The rate of improvement was 35.1% in the group of the patients who showed disturbance in the consciousness already on the admission, while the group with headache was the highest rate with 73.7%.
