소아 Mycoplasma Pneumoniae에 의한 폐렴의 임상적 고찰

김상갑,노상현,정은경,윤중근,김용태,박영봉 朝鮮大學校 附設 醫學硏究所 1991 The Medical Journal of Chosun University Vol.16 No.1

The author determined mycoplasma antibody titer in 127 cases of pneumonia who were admitted to the pediatric ward of Chosun University Hospital from December, 1989, to Novemver, 1990, and clinical investigation and statistical analysis were performed between mycoplasma antibody positive group and negative group. The following results were obtained: 1) In 127 cases of children with pneumonia, incidence of mycoplasma antibody positive cases was 22.8%(29/127). 2) Comparison of mean age between mycoplasma antibody positive group and negative group revealed significantly older in positive group than negative group (5.9±2.8 years, 2.7±3.5 years respectively), 3) The sex ratio was 1:1.23 in mycoplsma antibody positvie group and 1.6:1 in negative group. 4) There was no significant difference in the clinical symptoms and the physical signs betweem both groups. 5) There was no significant difference in total leukocyte count and ESR between both groups. 6) On radiological findings, the bronchopneumonia was significantly related to mycoplasma antibody positive group.

김신영,박재억,김창현,양성은 大韓齒科保存學會 2010 Restorative Dentistry & Endodontics Vol.35 No.1

30% 과산화수소를 함유한 전문가 미백제인 레메화이트(Remewhite, Remedent Inc., Deurle, Belgium)를 시험군 피험자 31명, 시험용 미백제에서 과산화수소를 제외한 동일한 제재를 대조약으로 대조군 피험자 31명에게 1일 3회씩, 2차례에 걸쳐서 시행하였다. 미백의 임상적 효용성은 Colorimeter, Vitapan classical shade guide를 이용하여 전체 색변화량(□E*)을 측정하였다. 14주 후와 26주 후의 색변화량을 측정하여 군 간 색변화량을 비교하였고, 각 군 내에서의 색변화량도 비교하여 다음과 같은 결론을 얻었다. 1. Colohmeter를 이용한 평가시에 시험군에서 전체 색변화량(□E*)은 대조군에 비해 통계적으로 유의한 차이를 보였고, Vitapan classical shade guide를 이용한 평가시에는 통계적으로 유의한 차이를 나타내지 않았다(p < 0.05). 2. 시간이 지남에 따라 색 복원 현상이 나타남에도 불구하고 미백 시행 14주 후와 26주 후에도 미백의 효과가 유지된다고 할수 있다. 3. Colohmeter를 이용한 평가시에 Vitapan classical shade guide를 이용한 평가시보다 작은 색변화량을 더 정확하게 측정할 수 있다. This study evaluated the efficacy of an office bleaching gel (RemeWhite, Remedent Inc., Deurle, Belgium) containing 30% hydrogen peroxide. 31 volunteers were recieved office bleaching with the RemeWhite for 3 times at one visit, total 2 visits. As control group, the same gel in which hydrogen peroxide was not included was applied to 31 volunteers with the same protocol. The shade change (□E*, color difference) of 12 anterior teeth was measured using Colorimerter and Vitapan classical shade guide. The shade change of overall teeth in the experimental group was significantly greater than that in the control group which was measured using Colorimeter. There was also a significant difference between baseline and 14 weeks or 26 weeks though color rebounding phenomenon occurred as time went by. Small shade change difference can be measured accurately using Colorimeter than using Vitapan classical shade guide.

김삼용,김현수,김종숙,박상준,최지영,윤환중,조덕연 충남대학교 의과대학 지역사회의학연구소 1995 충남의대잡지 Vol.22 No.2

Objectives : Clinical management of patient with lymphadenopathy requires judicious judgement of clinicians. Careful evaluation of lymph node enlargement by various clinical parameters will help to disclose the etiology of lymph node enlargement. This study was conducted to identify the clinical manifestations and etiology of lymphadenopathy in korean patients. Methods : A total 192 patients with lymph node enlargement were studied retrospectively. All patients who underwent excisional lymph node biopsy during the period from January 1992 to July 1994 were included. The lymph node biopsy and clinical records were reviewed and patient characteristics were analyzed by various clinical parameters. Results : A female predominance was noted in lymphadenopathy of tuberculosis (58.5%), Kikuchi's syndrome (70%). In lymphadenopathy of nonspecific, tuberculosis, kikuchi syndrome, per centage of patients younger than 40 years of age were 84.5%, 75.6%, 100%, respectively. In lymphadenopathy of tuberculosis and metastatic cancer, the duration of lymphadenopathy below 30days were 51.2%, 73.9%, respectively. The two most common etiology of cervical lymphadenopathy were nonspecific lymphadenitis (47.7%) and tuberculous (26.8%). The two most frequent etiology of supraclavicular lymphadenopathy were nonspecific lymphadenitis (46.3%) and metastatic lymphadenopathy (26.8%) and the most common etiology of axillary lymphadenopathy was nonspecific lymphadenopathy (34.5%). The most common frequent of lymph node enlargement with size below 1㎠ was nonspecific lymphadenitis, while above 2.25㎠ it was metastatic lymphadenopathy. Conclusion : Careful evaluation regarding patient age, sex, size of lymph node, consistency, location of lymph node, presence or absence of systemic symptoms should be pursued before performing a biopsy and management.

태권도 겨루기시 산소섭취량,호흡교환율,심박수,환기량 및 혈중 젖산농도 변화에 관한 연구

윤상화,김갑수,김현 龍仁大學校 武道硏究所 1998 武道硏究所誌 Vol.9 No.1

The purpose of this study was to compare changes of cardiorespiratory function, concentration of blood lactate while Taekwondo sparring. Subjects collected for this study were devided 2-types into 5 of A group(who won at national events more than three times within 1 year) and 5 of B group(who won at national events less than one within 1 year). For the process of the exercise, Taekwondo sparring, named to Exercise load used was that resting state insisted of 3 minutes, sparring time for 3 rounds(one round taking 3 mins and resting time for 1 min among rounds), and consumed to 10 min for recovery. Statistical methods used for the data analysis were paired t-test for appearing meaningful difference between groups. And error limited for group diffeence decided to p<0.05. The results were as follows: 1) There were significant differences of VO₂(ℓ/min), VO₂/W(ℓ/kg/min), and V??(ℓ/min) out of functions and concentration of blood lactate between groups after Taekwondo sparring.(p<0.05) 2) There was no significant difference of RER, HR between groups in resting time, after Taekwondo sparring, and after 10 minutes in recovering. (p>0.05) Synthethized above, The author considered taht Taekwondo sparring is to be one of the intermittent anaerobic exercise from a cardiorespiratory functional point of view. There was a meaningful difference to cardiorespiratory endurance between A and B groups, that is, A group was appeared to better than B, and two groups were intercorrelated between each bolld lactate and a cardiorespiratory function. For the fruther study, a more variety of programs advanced for scientific training related to validity can be applied to the field from the lab has required for the basic materials of the research.

RISC 프로세서의 파이프라인 처리방식에 관한 연구

유충열,김현주,이상일,김현욱 明知大學校 産業技術硏究所 1990 産業技術硏究所論文集 Vol.9 No.-

In the world of high speed computers, there are two main design philosophies-parallelism and pipelining. Pipelining is an effective method for reducing interchip communication while increasing performance. In this paper, we examine the pipeline handling strategy of RISC processors such as RISC Ⅱ, R2000, SPARC RISC CY7C600, and MC88100 in order to design MJU-DLX RISC in the future. Throughout the investigation, we determine the number of stage, number of register, and. control mechanism. Then, specification of MJU-DLX RISC has been presented for the future development.

저자들은 체중 증가와 전신 부종, 당뇨병을 주소로 내원한 여자 환자에서 폐 우중엽의 ACTH 염색 양성인 유암종이 쿠싱 증후군을 유발한 증례를 진단하여 수술적 제거 후 증상 완화를 경험하였기에 문헌 고찰과 함께 이를 보고하는 바이다. Fifteen percent of patients with Cushing's syndrome could be accompanied with nonpituitary tumors that secrets ACTH-the ectopic ACTH syndrome. Among them, bronchial carcinoid is one of the rare causes of the ectopic ACTH syndrome. We experienced a 60-year-old woman who showed conditions of weight gain, generalized edema, hypokalemia, diabetes mellitus, and right middle lung mass. Histologically, the tumor was diagnosed with bronchial carcinoid and was confirmed as an ectopic ACTH syndrome through immunohistochemical staining of ACTH. After resection of the lung mass, blood sugar, electrolytes, generalized weakness, and blood pressure improved (J Kor Soc Endocrinol 19:76∼81, 2004).
