      • Characterization of cricket song patterns and the behavior observation of Teleogryllus emma (Orthoptera:Grylloidea)

        Ji Chang Woo,Kim Nam-Jung,Lee Sang-Guei,Hwang-Yong Kim,Choi Hoon-Sik,Song In-Sun,Ko Jee Sun 한국응용곤충학회 2010 한국응용곤충학회 학술대회논문집 Vol.2010 No.05

        We analyzed the chirp sound and behavior of Teleogryllus emma with observation system, which was consisted of computer, ccd-camera and microphone. Computational methods of wavelet transformation and Self-Organizing Maps (SOM) were utilized to characterized the chirp sound of insect species for automatic counting in this study. Wavelets were initially applied to feature extraction of the chirp sound. Wavelet coefficients were accordingly calculated based on the basis function (e.g., Morlet). The obtained coefficients were subsequently provided to count number of chirps in each song. Sound structure of insect specimens consisted with long chirp and short chirp and the patterns of song were grouped by frequency of long chirp and short chirp. The song patterns of insect specimens were divided by Self-Organizing Map (SOM) that was used number of chirp as input data. Application of computational methods to automatic detection of chirp sound was further discussed for obtaining objective assessment in behavior science.

      • 장관에서의 액체 이동에 미치는 히스타민의 작용에 관한 연구

        송태호,김형근,엄대용,이상돈 중앙대학교 의과대학 의과학연구소 1975 中央醫大誌 Vol.1 No.1

        In vitro perfusion experiment was done to observe the effects of histamine on the transport of fluid from capillary into the intestinal lumen of rabbits weighing 2-2.8㎏. After performing the control perfusion with an artificial perfusate, histamine was added to the perfusing solution at a concentration of 1 ㎍/50ml perfusate and perfusion experiment was repeated. Mean capillary pressure (Pc), precapillary resistance(Ra), postcapillary resistance(Rv) and total tissue resistance (Rt) were calculated from the measured data of isogravimetric capillary pressure (Pci), arterial pressure (Pa), venous pressure (Pv), venous flow rate (Qv), luminal flow rate (Q_L) and weight of the intestinal loop. Decreased Pci from 19.5㎜ Hg of the control group to 15.2㎜ Hg of the histamine group had resulted from increased capillary permeability. And increased Pc was observed in the histamine group compared to the control due to the decrease in pre-to-postcapillary resistance ratio in the histamine perfused loop. Decreased Rt in the histamine group was also responsible in facilitating the fluid movement from capillary to intestinal lumen in addition to the effect of increased Pc. When Pc and Q_L were plotted linear relationships were observed and the slope of the histamine group was steeper than that of the control indicating increased volume movement "coefficient" in the histamine group.

        PCR-Restricition Fragment Length Polymorphism 방법에 의한 Borrelia burgdorferi Sensu Lato의 분류

        송혜원,김홍,박상욱,엄용빈,김종배,박성언,김근희 THE KOREAN SOCIETY FOR BIOMEDICAL LABORATORY SCINE 1999 Journal of biomedical laboratory sciences Vol.5 No.2

        라임병의 원인균인 Borrelia burgdorferi에 대하여 각 균종의 표준균주와 진드기에서 추출한 DNA를 template로 PCR을 실시한 후 그 증폭산물을 Alu I으로 처리한 restriction fragment length polymorphism (RFLP) 방법으로 각 균종의 연관성을 조사하고자 하였다. 표준균주로 RFLP를 실시한 결과 B. burgdorferi sensu stricto와 B. garinii의 RFLP 형태 (50 bp, 70 bp, 150 bp)가 유사하였으며 B.afzelii에서는 다른 RFLP형태 (50bp, 110bp, 150 bp)를 관찰하였다. 그 중 B. afzelii KK-1과 B. garinii HP1은 새로운 RFLP 형태를 보여 B. afzelii와 B. garinii는 각각 2 types의 subgroup으로 분류할 수 있었다. 진드기 DNA에서 는 B. afzelii를 포함한 각 균종에 대하여 모두 유사한 RFLP 형태를 보였는데, 진드기 DNA에서 확인된 B. afzelii는 KK-1과 같은 군에 속하는 것으로 사료되었다. For the classification of B. burgdorferi sensu lato strains, PCR-restriction fragment length polymorphism (RFLP) analysis was performed. PCR was carried out with B. burgdorferi sensu lato specific primer set (BB uni set), and amplicons of 470-bp DNA were digested with Alu I. The Alu I restriction polymorphism of the amplicons provided a useful tool for identifying B. burgdorferi sensu lato strains. Both amplicons from B. burgdorferi sensu stricto and B. garinii except HP1 strain showed identical RFLP pattern (50 bp, 70 bp, and 150 bp), but amplicons from B. afzelii and B. garinii showed two types of subgroups, respectively. The result of PCR-RFLP using extracted DNAs from ticks was similar to those patterns of B. burgdorferi species including B. afzelii.

      • 1976-77年의 釜山地方 冬季 異常寒波에 關하여

        宋泰鏞,文勝義,諸榮滿 慶北大學校 師範大學 1980 敎育硏究誌 Vol.22 No.-

        The abnormal cold waves of 1976-77 winter which caused lots of damages to overall of the Korean Peninsula were analyzed statistically and synoptically using the temperature data (1904-77) at Busan Station. The statistical results of this cold waves are summarized as follows: 1. The average temperature of January 1977 is -1.0℃, the rank is the 5th. The average minimum temperature of January 1977 is -4.5℃, the rank is only the 7th. 2. The number of successive cold days of this cold waves, namely, the number of days which lasted successively below 0℃ in daily average temperature, was the longest one (a total of 30 days) since 1905. The number of days which lasted below -5.0℃ in the average minimum temperature was also the longest one (20 days). 3. The temperature oscillation of more than 20.0℃ was respectively onetime in other cold years, on the other hand, 4 times in this winter, and the most marked oscillation was 27.2℃ in 3 days (February, 13-16, 1977). The results of synoptic analysis are as follows: 1. The influence of Siberian High during this cold period was greater than that of any other years, and also Aleutian Low was developed intensively, so thewest-high and east-low pressure system lasted for a ling time. 2. The pressure distribution of the upper level was similar to that of 1963 which resembles Baur Model C. So, the upper level temperature was very cold. The cause of this record-breaking cold waves was regarded as the southward movement of cold vortex from the Arctic region to the middle latitudes.

      • 한국대학생의 도덕사태 개념화 및 그 변화과정에 관한 연구(II)

        송명자,조용하,설기문,김상윤 東亞大學校 學生生活硏究所 1992 學生硏究 Vol.20 No.-

        This study aims to analyze the moral judgmental levels and the conceptions of transgressions of Korean college students in a series of multifacted events and the aspects of change in terms of moral judgmental level and conceptualizastion after with two years' college experience. The study was based on the Kohlberg's cognitive moral development theory and on the domain-distinction model in which children's intuitive abilities are stressed. This study was consisted of two sub-studies done in 1989 and 1991 respectively. The subjects of the 1st year study were 416 college students in four major cities(Seoul, Taegu, Kwangjoo, and Pusan). The subjects of the longitudinal analysis of second year study were 199 college students who could be followed up among the subjects of the 1st year study after two years. The instruments used in this study were Test of Moral Judgmental Development and Test of Conceptualization on Mulifaceted Events developed by the authors on the basis of Kohlberg's and Turiel's theories respectively. The following conclusions were obtained through the basis of the results and discussions of this study. First, Korean college students' false responses to moral issues decrease but the radical and anti-social responses increase after two years, and ther these responses are replaced by the level Ⅲmoral judgmental responses. Second, college students who are on the higher moral judgmental level conceptualize the transgression in social conventional and personal domains less permissible than those on the lower levels do. The students who are on the lower judgmental level reveal the decrese of nonpermissibility in social conventional domain with two years' college experience than those on the higher level do.

      • Ca^(2+)―작동성 Cl^-전류에 미치는 이차 전령들의 효과

        송인섭,이무열,방효원,엄대용,이상돈 중앙대학교 의과대학 의과학연구소 1993 中央醫大誌 Vol.18 No.3

        The anion movements across the cell membrane were regarded as apart of passive distribution according to the cation movements. Recently, from the developement of patch clamp technique new concept for anion channels were introduced. And their roles in the genesis of action potential and resting potential were noticed. So we clarified the existence of the chloride channel in the smooth muscle cells and studied its nature in regard to the roles of the second messangers. We used the whold cell voltage clamp technique to study the current responses induced by carbachol application in the circular smooth muscle cells of the gastric antrum of the rabbit. The results were as follows; 1. Application of the carbachol induced the increase of inward currents in the hyperpolarized potential ranges, and the increase of outward currents in the depolarized ranges. 2. Even in the cases of blocking all the known currents, these current components were observed. 3. Sodium ion removel from the external medium rarely affected these current responses, and the addition of cadmium ion did not make any remarkable change. 4. Known second messangers such as c-AMP, c-GMP, heparin, A1F_4 rarely affected these current components. 5. Lowering of intracellular calcium ion concentration drastically reduced these current responses. Form the above results we can suggest that the carbachol induced current responses contained chloride currents which were activated by only intracellular calcium ion, not by any other second messegers in the gastric antral smooth muscle cells.

        송우식,김인권,이상현,황윤정,안정용 대한악안면성형재건외과학회 2001 Maxillofacial Plastic Reconstructive Surgery Vol.23 No.5

        With the exception of gun shot wound, the incidence of penetrating injury of face and neck areas nonorganic foreign bodies is relative low. But the diagnostic evaluation and therapeutic management of penetrating facial wounds need careful decision, when the anatomic proximity of the major vessels and nerve is considered. Penetrating facial trauma with concomitant vascular injury present challenging problems, the immediate complication of this vascular injury are severe bleeding, hematoma formation, shock, obstruction of airway. The vascular injury is conformed by angiography. In this reprort, a industrial tool(long tack) fired by explosive air is penetrated into face and to neck. In angiograms penetrating injury of the vertebral artery is detected. We performed the embolization of the vertebral artery with coils and manual removal of the foreign body without any complication was followed.
