A successful therapy of community-acquired pneumonia requires appropriate empirical antimicrobial therapy. Etiology and antimicrobial susceptibility of major pathogens of pneumonia can differ by country. Therefore, an ideal treatment guideline of community-acquired pneumonia should be based on the studies performed in each country. We developed a treatment guideline for community-acquired pneumonia in immunocompetent adults in Korea. This guideline was developed by the joint committee of the Korean Society for Chemotherapy, the Korean Society of Infectious Diseases, and the Korean Academy of Tuberculosis and Respiratory diseases.

The building energy conservation possibility by introducing personal environment module(PEM)system was analyzed by DOE-2.1E building energy analysis program on the 6 stories office building. The results showed energy consumption of the building with PEM system could be increased more than the conventional VAV system when the occupant was not decreased. But the energy consumption rate in the building with PEM could be equal to VAV system when approximately 20% of the occupant is decreased. As a result, basically PEM system can consume more about 9.2%energy than the VAV system, but it can also have the possibility to save energy about 11.4% if it is operating with energy conservative way.

Cerebral angiography has been essential for the diagnosis of the intracranial aneurysms but. is sometimes accompanied by serious complications. Resolution of CT angiography was up-graded greatly to represent the three-demensional structure of vesseles since helical CT had been introduced. We have compared 26 cases of CT angiography and 28 cases of conventional angiography in terms of specificity and sensitivity for the diagnosis detectable aneurysm diameter. configurational diagnosis and diagnostic confidency. All results showed no statistical difference between CT angiography and conventional angiography. These should suggest that CT angiography could be replaced with conventional angiography for the diagnosis of ruptured aneurysms and even of unruptured aneurysms. resulting in the introduction of first screening modality of unruptured aneurysms.

With rapid growth of the internet, need for the mobile communication networks is increasing. In this paper, we implement and test Mobile IP Protocol in Embedded System. Our Mobile IP-based testbed consisted of two sub-networks and each sub-network was configured to operate independently through use of router. To satisfy integrated wired/wireless network model established on the testbed design and show generality of the testbed, we implemented mobile nodes, home agent, foreign agent and router on the basis of Linux operating system. As the results of the evaluation, we confirmed that mobile nodes operated properly according to Mobile IP Protocol.

Methylene blue와 Sodium Bis(2-ethl hexyl) sulfosuccinate 사이의 용매효과

송기동,김성현 조선대학교 기초과학연구소 1992 自然科學硏究 Vol.15 No.1

The metachromatic behavior of methylene blue(MB) with sodium bis (2-ethyl hexyl) sulfosuccinate(AOT or Aeorsol, OT), reversed micelle has been studied by absorption spectra viscosity, and refractive index. The effect of organic solvents(methanol, ethanol, isopropyl alcohol, and ethylene glycol) on the spectra has also been investigated. The critical micelle concentration (CMC) values of MB-AOT system are found to be 2.0mM and 2.1m M by means of the method of measurement of spectrophotometer and viscosity, respectively.

A 5-year-old Russian blue cat was referred to the Veterinary Medical Teaching Hospital of Chungnam National University with the history of anorexia, lethargy, weight loss(6.5 to 4.8 kg) 2 weeks ago. Abdominal ultrasonography showed the following : increase of echogenicity of liver, irregular shape of gall bladder, hyperechoic region around duodenum. Pancreatitis, cholangitis, hepatic lipidosis was diagnosed by the ultrasonography. Anti- inflammatory therapy, antibiotic therapy was administered. Abdominal ultrasonography is a efficient available diagnostic tool but serum fPL test reveals the highest sensitivity and specifity result for feline pancreatitis. SNAP fPL test is newly released that can check pancreatitis within 10 minutes by same princple of Spec fPL test used in Gastrointestinal Laboratory of Texas A & M Univerrsity.

This study was performed to identify risk factors for depression among the elderly in a rural area. A survey was done for the elderly living in Gosam-myenn, Ansung-kun during the period of July 28, 1997 and July 30, 1997. Demographic and sodoeconornic characteristics, and functional and health Status were assessed using a structured questionnaire, and the level of depression was measured by GDS score. The data obtained were analyzed by frequencies, percentage, t-test, ANOVA, and multiple regression, and the results were as follows: 1. The total sample consisted of 133 elderly. Of them, 47 elderly (35.4%) showed significant depressive Symptoms. 2. The GDS score was the highest for the group over 85 years of age (p < 0.05). Those living alone or widowed showed lower GDS score than those living with someone or married (p < 0.05). 3. The GDS score was the highest in the absolutely dependent group, followed by the partially dependent group, and the independent group (p < 0.01). The elderly who perceived their health Status as excellent showed the lowest GDS score. In contrast, those who had more than five chronic diseases showed the highest GDS score. 4. The elderly receiving financial and emotional support from their family or friends showed lower GDS score compared to those without any support. 5. The economically dependent group showed higher GDS score than that of independent group. 6. The elderly who involved in leisure activities showed lower GDS score than those without any involvement. 7. In terms of risk factors for depression, we found that perceived health Status, subjective economic Status, leisure activities, living arrangement and financial support were inversely associated with GDS score, whereas labor support was positively associated with GDS score. Based upon the above findings, this study suggests that these risk factors for depression in the elderly should be taken into consideration for a comprehensive mental health program for the elderly living in the rural area.

송주현,김영재,김정욱,장기택,김종철,한세현,이상훈 大韓小兒齒科學會 2010 大韓小兒齒科學會誌 Vol.37 No.1

본 연구는 항우식 제품인 Casein phosphopeptide-amorphous calcium phosphate(CPP-ACP)를 포함하는 치아크림, 불소 바니쉬, 저농도 불소 양치액을 치아에 도포하는 것이 단시간 탄산음료에 의한 법랑질의 침식을 예방할 수 있는지 살펴보기 위해 계획되었다. 법랑질 시편에 다음과 같은 항우식 제품을 도포하였고, 인공타액에 24시간 보관한 후, 콜라에 1분 증류수에 1분씩 5회 번갈아 처리하였다. 1군: 대조군(무처치) 2군: CPP-ACP 치아크림군 3군: 불소 바니쉬군(1,000 ppm F) 4군: 저농도 불소 양치액군(227 ppm F) 5군: 불소 바니쉬 + CPP-ACP 치아크림군 6군: 저농도 불소 양치액 + CPP-ACP 치아크림군 미세경도와 침식깊이를 측정하였고, Quantitative light-induced fluorescence(QLF)를 이용하여 안정된 형광 격자에 대한 부피 형광 변화인 ΔQ를 측정하여 무기질 감소량을 평가하였다. 6일 동안 실험을 반복하여 다음과 같은 결과를 얻었다. 1. 미세경도는 1군≤2군≤4군<6군<3군≒5군 순이었다. 2. 평균 침식깊이는 5군≒3군<6군<4군≒2군≒1군 순이었다. 3. ΔQ는 1군≒2군≤4군≤6군≤3군≒5군 순이었다. ΔQ의 감소율은 1군과 2군, 4군과 6군, 3군과 5군이 각각 유사하였다. 4. ΔQ는 미세경도와 강한 양의 상관관계를 나타냈고(r=0.96, p<0.05), 침식깊이와는 강한 음의 상관관계를 보였다(r=-0.96, p<0.05). The aim of this study was to evaluate the preventive effect of commercially available anticariogenic products, specifically, the tooth cream containing Casein phosphopeptide-amorphous calcium phosphate(CPP-ACP), fluoride varnish and low-level fluoride mouthrinse on enamel erosion induced by carbonated beverage in a short period of time. Enamel specimens were treated as follows and were then kept in artificial saliva for 24 hours followed by further processing by alternately soaking them in Cola beverage and in distilled water for 1 minute each five times. Group 1: control group (no treatment) Group 2: tooth cream with CPP-ACP Group 3: fluoride varnish (1,000 ppm F) Group 4: low-level fluoride mouthrinse (227 ppm F) Group 5: fluoride varnish + tooth cream with CPP-ACP Group 6: low-level fluoride mouthrinse + tooth cream with CPP-ACP Microhardness and erosion depth were measured and the mineral loss of each specimen was evaluated by measuring the volumetric fluorescence change(ΔQ) against the stable fluorescent grid using quantitative lightinduced fluorescence(QLF). The experiment lasted for 6 days repeated each day. The results were as follows: 1. The microhardness was increased as follows: Group 1≤2≤4<6<3≒5. 2. The mean erosion depth was increased as follows: Group 5≒3<6<4≒2≒1. 3. The ΔQ was increased as follows: Group 1≒2≤4≤6≤3≒5. The decrement of ΔQ was similar between group 1 and 2, group 4 and 6 and group 3 and 5. 4. The ΔQ showed positive correlation with microhardness (r=0.96, p<0.05), while it was negatively correlated to erosion depth (r=-0.96, p<0.05).
