        우리나라 주택의 외관형태의 다양성에 관한 연구 : 1980년대 이후 건축가가 설계한 주택을 중심으로

        홍숙경,한기정,손세관 대한건축학회 2004 대한건축학회논문집 Vol.20 No.5

        The purposes of this study are to analyse the varieties of external shapes of detached houses in Korea after 1980s and to arrange the characteristics of those. For these purposes, 152 houses designed by architects have been selected. And the general form, the relationship of external form factors, the intermediate spaces in each form, the arrangement of internal spaces, especially livingroom and master bed room, and the roof styles of those were analysed by typological method. The results of analysis are as follows; Firstly, the general form of houses in Korea after 1980s is ㄱ-shape. Secondly, the external forms of houses are composed with complex form factors, and these form factors are annexed, adjoined, and crossed at right angles. Thirdly, the separated form factors are connected with hallway or staircase. Fourthly, the arrangement of a living room and a master bed room are identified by adjoined each other on the first floor. Fifthly, the representative roof style of architect-designed houses in Korea is even roof.

      • 韓國産 모기의 生態學的 硏究 : 第二編 韓國産 Anpheles屬 모기의 生態學的 硏究

        元炳徽,洪漢基 東國大學校 1968 論文集 Vol.5 No.-

        Biological investigations were carried out in the western plain area of Okku-gun, Cholla-pukdo province in 1964, in the hilly area of Asan-gun, Chungchong-namdo province in 1965, and in mountinous area of Andong-gun in 1966, Chongsong-gun in 1967 and Yongju-gun, Kyonsang-Pukdo province in 1963 and 1968. 1. Anopheline mosquitoes found during the investigation period are as follows: 1) Anopheles sinensis Wiedemann. 1825 2) Anopheles yatsushiroensis Miyasaki. 1951 3) Anopheles sineroides Yamada. 1925 4) Anopheles koreicus Yamada & Watanabe. 1918 5) Anopheles lindesayi japonicus Yamada. 1918 1),2),3) among the five species of Anophline mosquitoes were distributed in all of the studied areas, however 4) and 5) were found in the mountinous area. 2. Population density and seasonal appearance of Anopheline mosquitoes. A. sinensis is the widely distributed and predominant species in the all investigated areas, and shows the higher density in the plain area than the mountinous area. This species is to be appeared from begining of march and to be disappeared in October, and shows the peak population density in July during the mosquito season. A. yatsushiroensis is a widely distributed common species, and to be appeared from May to October with two peaks in June and September. The population density of this species in mountinous area is higher than the plain area. A. sineroides is widely distributed species but rare. Seasonal appearance of this species was from May to October and higher population was shown in mountinous area. A. koreicus and A. lindesayi japonicus is the species to be appeared in mountinous area and colledted from May to October, however A. lindesayi japonicus is very rare and limited breeding species in the mountinous area. 3. Feeding habits of Anopheline mosquitoes In the early spring A. sinensis was collected in open air by daytime cowbiting collection under the low temperature and earlier day of catching was the third of March and latest day was the 14th of May. The total average number of A. sinensis collected by per day was 5.7 mosquitoes in Sangchapo village and 7.5 in Hachapo in 1966. The number of A. sinensis collected in the afternoon was higher than the morning and fair day was higher than cloudy. The feeding activity at night was continued throughout the night. The peak period of feeding activity through the noght had shown in different time in each month such as between 21.00-22.00 hours in June, 24.00-01.00 hours in July, 03.00-04.00 hours in August and 21.00-22.00 hours in September. The minimum temperature for feeding activity was 14℃ and optimum was between 24-25℃ in the field. Night time feeding activity of A. yatsushiroensis was throughout the night and shown two peak periods at two hours before and after from the sun-rise and the sun-set. The other species of sineriodes and loreicus were not shown the special peak period of feeding at night. A. sinensis shown the zoophilism, however in Okku area the human biting rate was the 16 times higher than Asan area, and a number of biting mosquito in out door were 1.3 times higher than indoor. The light attraction of A. sinensis is 2.5 times higher by one candle food. The human biting rate of A. yatsushiroensis was 13.4% higher than A. sinensis by experimental feeding test. 4. Resting habits of Anopheles mosquites Anopheline mosquitoes were collected in most of the places in house, but the main resting places were cow shed (82.1%) and pigsty(12.4%). Out of 7.125 Anopheline mosquitoes collected from the houses since from 1964 to 1967, and A. sinensis was 88.2% A. yatsushiroensis 1.4%, A. sineroides 3.5% and koreicus 6.9%. From the resting place collections in outdoor, A. sinensis and A. yatsushiroensis are 61.6% and 52.4% from parsley field, 9.1% and 24.0% from seed bed of rice field, and other 11% and 9% fromother resting places such as bean field, vegetable, potatoes and so on. In the Experimental trap but collection, the collected number of A. sinensis in exit window trap were 76.4% in July and 81.3% in August, and 95.7% in July and 97.1% in August for A. yatsushiroensis. 5. Out of 1349 female of A. sinensis released from DDT sprayed room(DDT 2g/㎡), 29% of A.sinensis were collected from exit window trap and 42% of A. sinensis were dead mosquitoes in the sprayed room. 24 hours survival test of A. sinensis which was collected from exit window trap showed the 74% mortality and 8% of total released mosquitoes was only alived. 6. Parous rate of A. sinensis in Asan area were 50.5% in June, 64.4% in July, 82.7% in August, 93.5% in September and the parous rate of A. yatsushiroensis were 71.9% in June, 74.3% in July, 87.9% in August. 7. Main breeding place of Anopheline mosquitoes were rice field, stream, pond and parsley field. 8. Malaria in fection of Anopheline mosquitoes Two A. sinensis were found to be positive for sporozoite from salivary gland dissection out of 4018 females in 1967 and one A. yatsushiroensis was found to be positive for oocyst from stomach dissection out of 89 females in 1966. In 1968 four species of Anopheline mosquites were tested for experimental infection of malaria (p. vivax), and one A. sinensis was infected for oocyst among eight females tested and three A. yatsushiroensis were infected for one oocyst and two sporozoite among nine tested females. Other species were not infected. 9. Filaria (B. malayi) infection of mosqitoes One female of A. yatsushiroensis was found to be infective of filarial larvae out of 89 dissected mosquitoes in 1966 and six females of A. sinensis were found to be positive out of 1380 dissected females in 1967. Experimental infection of microfilariae(B. malayi) to the Anopheline mosquitoes were carred out in 1968. Twelve females of A. sinensis were infected among thirty five tested females, ten females of A. yatsushirionsis were infected (62.5%) out of the sexteen, and nine of A. sineroides were infected (90%) among ten females.

      • 시간가변계수를 이용한 Feldstein-Horioka 저축보유계수 추정

        오근엽,김봉한,김홍기 충남대학교 경상대학부설 경영경제연구소 1997 경영논집 Vol.13 No.1

        본고에서는 시간가변계수모형을 이용하여, Taylor의 자료를 가지고 FH의 저축보유계수를 추정하였다. 이에 이용된 계량기법은 Kalman Filter와 TVC 공적분 방법이다. 그 결과 우리는 양자의 결과가 크게 다르지 않음을 보았다. 또한 우리의 결과는 기존의 논문중의 대표적인 것중의 하나라고 보여지는 Taylor의 결과에도 크게 다르지 않았다. 다만 본 논문에서는 FH저축보유계수의 시간별 변화를 Taylor에 비해서 훨씬 자세하게 볼 수 있게 되었다는 점에서 그 의의가 있다.

      • 비선형 캐리어 제어 부스트 정류기 특성에 관한 연구

        이제환,전기영,조정민,한홍일,한경희 明知大學校 産業技術硏究所 2000 産業技術硏究所論文集 Vol.19 No.-

        Average-current mode controlled boost rectifier is most universally used at present, While the method gives high power factor, low harmonics distortion, has drawbacks such as 3-feedback loop, complex component, difficulty of control-circuit design, and high cost. Research for improving these problem has been carried out, and Nonlinear Carrier(NLC) Control method is representative. This control method has easy algorithm for control, and its feedback loop and control components are reduced. In this paper, the control method was evaluated by simulation through Matlab/Simulink, and experimented with 550W boost rectifier. As the result, that can get high power factor above 0.95 and low harmonic distortion was confirmed. Also, a good dynamic response on line and load variation was confirmed.

        사람 뇌척수액중 Transthyretin의 항산화작용

        양성렬,최기오,박종근,류문희,홍석노,김수한,안봉환,이제혁,이민화 대한신경외과학회 1994 Journal of Korean neurosurgical society Vol.23 No.4

        Protective effects of human cerebrospinal fluid antioxidants against enzyme inactivation caused by metal-catalyzed oxidation systems were investigated. When purified glutamine synthetase(GS) was incubated with human cerebrospinal fluid(CSF), the enzyme was progressively inactivated. Catalase and EDTA could inhibit the enzyme inactivation by 50-80%. Small-molecular(Mr< -10,000) fraction of CSF inactivated the exogenous GS, but large-molecular(Mr> -10,000) fraction did not. The GS inactivation by the small-molecular fraction was also markedly inhibited by catalase and EDTA. These results suggested that metal-catalyzed oxidation is involved in the GS inactivation by the small-molecular fraction of CSF. Dithiothreitol(DTT) was shown to inhibit almost completely the oxidative inactivation of GS by CSF. However, DTT inhibited only partially the oxidative inactivation of GS caused by small-molecular fraction of CSF. When large-molecular fraction of CSF was separated by anion-exchange HPLC chromatogrpahy, there was a peak of antioxidant activity inhibiting the small-molecular fraction-induced GS inactivation in the presence of DTT. The antioxidant activity was neutralized by monoclonal antibodies to transthyretin. Purified transthyretin was found to efficiently inhibit ascorbate/Cu^(2+)-induced GS inactivation in the presence of DTT. Uric acid and glucose did not show any protective effect on the GS inactivation in the same condition. The above results suggest that metal-catalyzed oxidation occurs normally in human CSF, and that transthyretin may play an important role as a CSF antioxidant in protecting proteins from metal-catalyzed oxidation.

        이경복,박기현,한민홍 한국경영과학회 2001 한국경영과학회 학술대회논문집 Vol.- No.1(2)

        This paper describes a method for saving traffic accident images in SMC(Smart Media Card), which is served as objective proof. SMC served being small-sized, strong, easy to attach and take off, which enables users image and voice-information service such as digital camera, MP3 Player, PDA and so on. Above all on account of it's high-speed in saving. The result of using SMC is saved pictures for 15 second before and after traffic accident image(320×240×8bit) into 8 frames/sec using a voice-recognition method or image recognition method. These pictures can be revived by PDA or mobile computer through up-loading serial/parallel communication or USB communication. This method could be applied to develop BLACKBOX.

      • 사고음 인식에 의한 교차로 교통사고 감지

        김병철,박기현,한민홍 한국경영과학회 2001 한국경영과학회 학술대회논문집 Vol.- No.1(2)

        This paper presents the detection-method of a traffic accident at a crossroads by the recognition of crash-sound. For the detection of crash-sound, the FFT algorithm is used and found characters of crash-sound. The result of using FFT algorithm is that crash-sound has a higher frequency than noise of roads. Then the using that result. We can detect the crush sound and know when the accident happen exactly. This method will be used the development of vision- blackbox.
