申鉉成,吳是煥,李敏雄 대한화학요법학회 1986 대한화학요법학회지 Vol.4 No.2

A total of 25004 cases of clinical materials from patients was collected in H hospital from January 1974 to December 1984 in Seoul. Among the materials, 7773 cases of the clinical specimens were identified as pathogenic, organisms. The numbers of cases of E. coli isolated from the specimens were 1838 except for cases of incubation of human feces. Infectious pattern and antibiotics sencitivity of the pathogenic organisms and E. coli were as follows: Total clinical specimens, and isolation rate of E. coli from total clinical materials and to the identified pathogenic organisms were increased more than 2 times in 1982 to 1984 comparing to the year in 1974 to 1976. The range of percentage of all identified microorganisms to total clinical specimens was 27.0~34.6% yearly. Isolated ratio E. coli to total specimens was 7.4% and the ration of isolated E. coli to total isolated pathogens was 23.6%(1838/7773). The isolation ratio of E. coli per each patient was 1.323 for male and 1.21 for female. The isolation ratio-of male to female was 1 : 1.88. The highest number of E. coli was found in May for male and June for female according to monthly isolation. On the other hand the lowest number of E. coli was observed in February for male and October for female respectively. In seasonal fluctuation of the isolated orgainsms from patients specimens, the isolation rate was maximized in fall for male, and in summer for female, but the ratio was generally decreased in winter season. The age specific isolation rate of E. coli was 27.8% under 10 year old group for male and 27.1% in 20~29 year old group for female, but the frequency of the organisms was observed lower in 10~19 year old group in both sexes. The isolating sources of specimens in male were 41% in pus, 22.2% in urine and 20.1% in throat swab, and the sources in female were 59.7% from urine, 14% in pus and 11.3% from vaginal discharge. The susceptibility to antibiotics studied for 11 years was all less than 40% in streptomycin, cephalothin, chloramphenicol, carbenicillin, tetracyclin, ampicillin, erythromycin and penicillin except for 73.6% in gentamicin and 52.8% in kanamycin. But in the last 2 years, the antibiotics showing over 90% sensitivity against E. coli were cefotaxime, sisomicin, cefoxitin, amikacin and pipemidic acid.

This study is aimed to find ways to analyze the current nighttime use of mountainside Mt.Bomunsan Park and thereby, to increase the efficiency of mountainside parks situated in urban areas, by case-studying other similar parks whose nighttime use has been facilitated. Also, the study focused on identifying diverse leisure activities for urban citizens to enjoy at night at such parks. First, the Mt.Boumunsan Park area was analyzed in its current nighttime use, space by space, to learn how the park is used by the public at night. Second, other parks whose physical environment is similar to that of Mt.Boumunsan Park were case-studied so that the result could be reflected on the operation of Mt.Boumunsan Park. Third, revitalization suggestions were made for the visit to Mt.Boumunsan Park during nighttime so that they can be referred to as basic data when planning and designing a park in the future for more efficient spacing. It is anticipated that when planning and designing is under consideration to improve Mt.Boumunsan Park, it is better to devise, after taking into account the local government's financial status and the public opinions, a short-and mid-term plan will better serve citizens than a non-feasible long-term master plan.

정신분열증 환자의 性(Sexuality)에 관한 임상적 고찰

최시현 大韓神經精神醫學會 1982 신경정신의학 Vol.21 No.3

1981년 8월부터 1982년 2월말까지 국립정신병원에 입원중인 정신분열증 환자 358명 중 조사 가능한 260명(남 124명, 여 136명)을 대상으로 하여 이들의 개인적 배경 전반을 알아보고, 性的행동장애, 思考 및 知覺상에 보인 性的문제에 대한 발현양상 및 빈도를 中心으로 조사한 결과 다음의 몇가지 특징을 알 수 있었다. 1) 性的문제를 보인 환자의 男女比는 비슷했고 20-30대가 93%로 거의 대부분이었고, 학력은 고졸 이상이 84%로 비교적 높은 교육정도를 보였고, 대부분이 미혼이었으며 아형별 진단분포는 만성미분화형과 망상형이 대다수였다. 2) 정신분열증환자, 특히 망상형과 만성미분화형의 환자들이 그들의 사고와 지각 및 행동에 있어 性的문제를 상당수에서(38.8%) 가지고 있었다. 사고면에서는 123례(47.3%)였고, 지각에서는 50례(19.2%)였으며, 행동에서는 108례(41.5%)의 빈도를 보였다. 3) 사고장애에서, 과도한 이성에의 집착이나 근친상간 및 사고나 충동의 대다수(90.9%)가 발병전에 이미 경험된 예였고, 동성애적 경향을 보인 환자의 63.6%가 망상형이었다. 지각장애에서 女子는 환청이, 男子는 환시가 性比상 다소 많았고, 환후는 적었다(1.9%), 행동면에서 독신주의, 성적무감동, 성욕 全無 등이 13.8%로 가장 많이 나타난 것은 장기간 입원의 결과와 향정신약물의 영향을 배제키 어려웠다. 근친상간이나 강간의 경우 대부분 조정망상, 환각과 현실감 결여로 인한 점이 주목할만 하였다. 4) 성적 망상이나 환각이 단독으로 존재하는 경우는 드물며 대부분 다른, 과대, 피해, 정치 등의 망상 내용과 복합된 양상으로 존재하고 있었다. 5) 정신분열증 환자에서 性(Sexuality)에 관련된 부분이 상당한 부분(38.8%)을 차지함으로 향후 이 부문에 원인적, 역동학적, 현상학적인 각 측면에 대한 보다 광범위하고 체계적인 연구가 이루어져야 할 것으로 생각된다. The author attempted to study the sexuality in schizophrenic patients in terms of their sexual bebaviors, thought and perceptal disturbances by the method of statistical evaluation. The subjects are 260 schizophrenic patients who were hospitalized in National Mental Hospital during the period of seven months(Aug. 1, 1981-Feb. 28, 1982). Some of their characteristics are as follows: 1) Sex ratio is about the same(F:F; 1:1.1). The marital state is more than half of them(69.3%) are single. The divorce or seperated one are 4.0%. In the educational level, more than three-fourth of them(84.1%) are high school graduates. Regarding to subtype chronic undifferentiated and paranoid types consist of 91.1% of total cases. 2) The majority of patients show sexual problems in their behaviors(41.5%), disturbance in thoughts(47.3%) and perceptions(19.5%). 3) In their thought disturbances, the preoccupation of hetero sexual matters(90.9%), the incestuous thoughts and ipulses(81.0%) occurred mostly at prepsychotic period. The homosexual tendency is predominant(63.6%) in paranoid type. In perceptual disturbuuces, the female shows more of auditory and the male shows of more of visual hallurination. however, the olfactory hallucination(1.9%) is less common both sexes. In the sexual behaviors, the celibacy, the seual apathy, and libidinal impotence are commonly seen in this study(13.8%). The reason seems to be related to the chronicity of hospitalization could we exclude side-effects from neuroleptics. The subject, who committed incest and or rape reveal the symptoms of idea of references, hallucinations and poor reality Resting. 4) The sexual nature of delusion or hallucination is rarely occurred singly, instead they occur mostly in combined, such as various combinations of grandiose, persecutory, religious, predictive and political themes. As a concluding remark, the author strongly feels that the sexual problems in schizophrenic patients appear to be common phenomenon. Thus the more organized studies in terms of etiology, psychodynamics, and phenomenology of sexuality in the schizophrenics are needed.

조정현,김학수,김시호 충북대학교 컴퓨터정보통신 연구소 2006 컴퓨터정보통신연구 Vol.14 No.2

RFID는 사용되는 주파수에 따라 ID 확인과 실별, 물류, 전자지불, 출입통제, 교통카드 등에 사용되고 있다. 그중 UHF대역의 RFID 시스템은 유비쿼터스의 대표기술로 인식되고 있으며, 바코드를 대체하는 기술로 그 응용분야가 급속히 증가할 것으로 기대되고 있다. 본 논문은 EPCglobal Class-1 Generation-2 표준을 만족하는 UHF RFID 태그의 구성과 RF/아날로그 전단부 회로 설계를 설계하였다. 본회로는 매그너 칩의 0.25 CMOS 공정 파라미터를 사용하여 설계하였다. RFID systems can identify, trace and manage the objects equipped with a semiconductor tag chip. Tag chip stores and extracts the electronic code in the tag memory through RF signals. A typical RFID system consists of a reader and a number of tags. This paper describes the design of analog circuit of a RFID tag that is compatible with the EPCglobal Class-1 Generation-2 Protocol.

효소 중합반응에 의한 인공 cDNA 클론의 형성

유시현,권무식 成均館大學校 科學技術硏究所 1992 論文集 Vol.43 No.2

The sequence-specific DNA binding protein, PU.1 common to macrophage and B cell in mammals, is one of the transcription activators. Its DNA binding activity seems to correlate with the phosphorylation of specific serine residue(s). It is, however, not clear that which serine(s) could be phosphorylated for the activation of PU.1. To understand the phosphorylation mechanism of the transcription factor, the first nucleotide coding the 11th amino acid [TCC] of PU.1, "Thymidine", was substituted with "Guanidine" by site-directded mutagenesis. The mutant PU.1 cDNA restricted by Xba I and Hind III, was ligated into Xbal-HindIII cut pBluescript KS+, and then transformed into E.coli JM109 to generate a new mutant clone of PU.1. The mutant will be instrumental in evaluating a plausible phosphorylation site of PU.1.

형판정합기반 영상 정규화를 통한 고유얼굴(Eigenface)알고리즘 성능개선 방법

최영규,신현금,장경식 한국기술교육대학교 2003 論文集 Vol.10 No.1

A new approach for face recognition is proposed. Our method adopts the Eigenface algorithm as the main classifier, but improves performance by normalizing input images based on template matching technique. Firstly, the two eye regions are evaluated by template matching with a set of ordinary eye templates. The scale and rotation factors are estimated based on the distance and angle between left and right eyes, and we generate a normalized face of the input image, and finally, it is provided as the input of the Eigenface algorithm. Since, Eigenface is a good recognition method but is vulnerable to image variations such as rotation and illumination conditions, our face normalization approach could be very effective.

Cerebral palsy is a static encephalopathy that is caused by multifactorial disorders. Treatment should be approached by a team of physicians from various specialties. But usually the detection of abnormal behavior might be delayed. We used Bayley scales for the patients which were transfered for the evaluation of behavior disorder and tried to detect earlier as cerebral palsy. We recommended selective posterior rhizotomy to the patients who was spastic quadriplegia as early as possible. We evaluated 154 patients with Bayley scale and 85 patients were followed. Among them we applied selective posterior rhizotomy to 25 patients who were spastic quadriplegia. The result was very excellent. We conclueded that Bayley scale is a good tool for evaluation of developmental delay esp. cerebral palsy earlier than usual physical examination and selective posterior rhizotomy is satisfactory treatment method for spastic quadriplegia.

This study was performed to measure the skin absorbed doses from full mouth standard intraoral radiography(14 exposures) in bisecting angle and paralleling techniques. Thermoluminescent dosimeters were used in a phantom. Circular tube collimator(60mm in diameter, 20cm in length) and rectangular collimator(35mmX44mm, 40cm in length) were set for bisecting angle and paralleling techniques respectively. All measurement sites were classified into 8 groups according to distance from each point of central rays. The results were as follows: 1. The skin absorbed doses from the paralleling technique were significantly decreased than those from the bisecting technique in both points at central ray and points away from central ray. The percentage rates of decrease were greater at points away from central ray than those at central ray. 2. The skin absorbed doses at the lens of eye, parotid gland, submandibular gland and thyroid region were significantly decreased in paralleling techniuqe, but those of the midline of palate remained similar in both techniques. 3. The highest doses were measured at the site 20mm above the point of central ray for the mandibular premolars in bisecting angle technique and at the point of central ray for the mandibular premolars in paralleling techniques. The lowest doses were measured at the thyroid region in both techniques.

This paper analyzes urban residents' preference on rural tourism using a survey data. The results show that even though urban residents are unaware of rural tourism, people who have experienced rural tourism set a high value on it. Urban residents are willing to pay about 93,600Won for rural tourism. These results indicate that there is a lot of potential demand for rural tourism. The results of this paper could be an important information to develop the rural tourism.

급성 심근염환자에서 발행한 완전 방실차단을 영구 심장박동 조율기로 치료한 1예를 경험하였기에 문헌고찰과 함께 보고하는 바이다. Myocarditis, an inflammatory process involving the myocardal wall, may be caused by most infectious agents. Irrespective of its etiology, it presents commonly with evidence of heart failure, hypotension, and various electrocardiographic abnormalities. Patient with myocarditis may be asymptomatic or may have a rapidly progressive fatal disease. Medical management of patients with myocarditis includes specific therapy for underlying infection and control of the complication of myocarditis such as congestive heart failure and arrhythmia. Recently we had experienced myocarditis with complete atrioventricular block in 37-year-old man. Although he had shown complete recovery of heart failure, he had shown complete atrioventricular block, so we inserted permanent pacemaker. We report it with review of the literature.
