Acinetobacter species is a non-fermentative aerobic gram-negative coccobacillus that is an important pathogen found in nosocomial infections. Recently, multi-drug resistant Acinetobacter baumannii (MDR-AB) infections have been increasing and pose a serious problem. Most such infections present as bacteremia, pneumonia, or a wound infection; however, CNS infections are very rare. We herein present a case of ventriculitis caused by MDR-AB in a 37-year old man after a neurosurgical intervention. The patient was successfully treated with intrathecal colistimethate.

연령에 따른 한국인 손 피부색 차이 분석

홍다검ㆍ이희경ㆍ이정현(Da Geom HongㆍHee kyung LeeㆍJeong Hyun Lee) 한국인체미용예술학회 2016 한국인체미용예술학회지 Vol.17 No.1

Recently, nail industry trends have been shifting from polish nail to gel nail. Because of the popularity of gel nail, the criteria for customers to choose colors have significantly changed. Therefore, there has been a rising demand for a nail color which goes well with skin color, not with the color of clothes, makes the hand more beautiful. Unlike a face, hand skin color isn’t corrected through makeup. Therefore, it is more difficult to find a color which is well matched with the skin tone. In this sense, the accurate analysis and classification of hand skin color which is the first step in the selection of nail color are required. However, it’s still very hard to find studies on hand skin color. To figure out the characteristics of Koreans’ hand skin color by age, this study analyzed differences in hand skin color by age after measuring the tone of the back of the hand and conducting quantitative analysis against 300 women living in Busan, Ulsan and Gyeongnam. The results revealed statistically significant difference (p.001). As the respondents were younger, a bright skin tone was observed. According to analysis on the distribution by the rank, ‘20s’ was the highest with 46% among those with a bright skin tone within top 100 ranks. In top 300 ranks, in contrast, ‘50s’ was the highest with 46% while ‘20s (8%)’ was the lowest. In terms of a skin tone, there was a considerable difference between ‘20s’ and ‘50s.’ Even though no big difference was found between ‘30s’ and ‘40s,’ a skin tone was brighter in the latter.

To study the changes of EGF receptors in the rat liver regeneration and hepatic carcinogenesis, ^125I-EGF binding sites were measured in the regenerated liver cell membrane after partial hepatectomy of normal rat and 3-methyl-4-dimethylaminoazobenzene treated rat. 1. EGF binding sites (Bmax) in the normal rat liver cell membrane were 553.8fmole/mg protein and were markedly decreased at the 1st day after partial hepatectomy. These sites were increased at the 3rd day(Bmax-161.0fmole/mg protein) and were 29% of the normal liver EGF binding sites. 2. EGF binding sites (Bmax) in the normal cell membrane of the 3-methyl-4-dimethylaminoazobenzene-treated rat, were 72.8fmole/mg protein and were significantly less than those in the normal rat live cell membrane. At the 1st day after partial hepatectomy, EGF binding sites were markedly decreased and increased at the 3rd day (Bmax=155.8fmole/mg protein). 3. Kd values in EGF receptor binding were not much altered in both liver cell membranes of the normal rat and the 3-methyl-4-dimethylaminoazobenzene treated rat. From these result, it is suggested that decreased EGF binding sites in the liver cell membrane of regenerating rat liver and 3-methyl-4-dimethylaminoazobenzene treated rat may be due to the alteration of EGF receptor number.

제주도 전 지역의 특정위치를 선정하여 그 위치에 따라 지하 60m, 61m, 87m, 99.5m, 220m까지 깊이별로 화산암 시료를 채취하여, 이 시료에 대한 SIMS, XPS와 Mossbauer spectroscopy의 실험결과를 보고한다. UHV chamber에서 분리 이온화에 의해 생겨 난 parent 이온들로부터 cracking pattern들에 대해 연구하였고, 그 parent 이온들은 Si??, Al??, Ca??, Mg??, Fe??, Fe??, Na?, k?등으로 나타났다. 이 시료들에 대한 XPS 실험에서 wide scan analysis를 통하여 시료 표면에서 Al, Si, Ca, O, Fe, Na 등의 원소가 존재하고 있음을 알 수 있었으며, narrow scan analysis를 통하여 이들 대부분이 single compound state를 나타내고 있음을 발견할 수 있었다. 화산암에 대한 Mossbauer spectrum으로부터 olivine, pyroxene, ilmenite에 의한 세쌍의 quadrupole splitting을 얻었으며, 각 광물에 함유된 Fe는 약간의 Fe??를 제외하고는 거의 모두 Fe??상태임을 확인하였다. We are reporting the results of measurements of the SIMS, XPS, and ??Fe Mossbauer spectrum for powder samples of volcanic rock which has been distributed throughout different areas on Cheju island, each in different depth beginning at 60m then 61m than 61m, 87m, 99.5m, and 220m. We have studied the cracking patterns from parent ions which are created by dissociative ionization in the UHV chamber. The parent ions were Si??, Al??, Ca??, Mg??, Fe??, Fe??, Na??, and k??. In the XPS results for these samples, we find the existence of elements Al, Si, Ca, O, Fe, Na on their surfaces through the wide scan analysis. Also, the single compound state has appeared in a greater percentage of the them through the narrow scan analysis. The Mossbauer spectrum consists of well defined quadrupole doublets having a dominant 2+ charge state with a small percent having a 3+ charge state. These indicate the presense of olivine, pyroxene, and ilmenite.

Malignant fibrous histiocytoma rarely occurs in the jaws. Although the histogenesis of this tumor remains controversal, it is best regarded as a primitive and pleomorphic nature reflected by collagen production and occasional phagocytosis. It is common for metastatic foci to appear in lung and regional lymph node. There are variable treatments such as radiotherapy, surgical excision or combination, therapy of surgical excision, chemotherapy and radiotherapy. With the review of literatures, the authors report the clinical study of two cases of malignant fibrous histiocytoma of the jaw.

Three different doengjang(fermented soybean paste) were prepared by using B. subtilis SS103 with high angiotensin converting enzyme(ACE) inhibitory activity, Asp. oryzae and mixed culture of two organisms, respectively. Quality characteristics and the inhibitory activity were compared. β-Amylase activity rapidly increased during 30 days of fermentation, but lower activity was found in doenjang prepared with B. subtilis. However, α-Galactosidase activity decreased for 15 days of fermentation and little activity was observed after that fermentation period. Protease production tended to increase during the fermentation. High protease activity was found only in doengjang prepared with Asp. oryzae, but the doengjang prepared with B. subtilis SS103 showed very low activity. Total isoflavone content at 90 day fermentation was the highest in doengjang prepared with mixture of Asp. oryzae and B. subtilis. ACE inhibitory activity increased during the fermentation period. The highest activity was found in doengjang made with mixture of Asp. oryzae and B. subtilis. Sensory evaluation on doengjang itself and its soup indicated that doengjang made with mixture of Asp. oryzae and B. subtilis showed higher acceptability on taste, flavor and color than those prepared with only Asp. oryzae or B. subtilis, respectively.

The main purpose of this study is to identify and evaluate the depressive states for the patients with chronic pulmonary tuberculosis. A questionnaire(Self-rating Depression Scale, SDS) survey was performed toward 57 pulmonary tuberculosis patients with initial treatment who started chemotherapy and 53 pulmonary tuberculosis patients with retreatment, admitted to one tuberculosis-centered hospital and two general hospital. Fifty three healthy persons as control group were investigated with the same questionnaire for comparison. The survey was performed from July to August 1996. The results are as follws : 1. The patients had significantly high scores in the depression than control and the patient with retreatment showed significantly high scores in the depression than the patient with initia1treatment(P<0.01). 2. The depressive levels of the patients were associated with duration of admission and the expectancy of recovery (P<0.05). 3. The percentage of the subjects with 40 or more scores tentatively classifiable as psychologically depressed was 67.1% of the total subjects, 48.4% of the control groups, 75.0% of the patient with initial treatment and 84.1% of the patient with retreatment. Because patient with pulmonary tuberculosis with initial treatment showed higher depression scores than normal persons, and patients with retreatment due to failure of initial treatment showed higher depression scores than initial treatment, it is necessary to give attention to depression of the patients during treatment of pulmonary tuberculosis.

RF 마그네트론 스퍼터링 방법에 의한 (Ba, Sr)TiO₃박막의 특성

홍석민,조정희,김호건,김옥경 漢陽大學校 工學技術硏究所 1996 工學技術論文集 Vol.5 No.1

A sputtering target(BaxSr1-xTiO3) is obtained by changing the mol% of Ba and Sr. Pt is evaporated on the SiO2/Si substrate as a bottom electrode, and subsequently the BaxSr1-xTiO3 thin film is sputtered. Or, for obtaining the MIS structure Pt is not used, and directly thin film is sputtered on the Si substrate. Then, the capacitor structures(MIM, MIS) have been obtained by evaporating Al as a top electrode after post-annealing. Our results show that produced thin firm is found to have Perovskite structure according to the XRD measurement and shows better crystal growing phenomena on SiO2/Si substrate than those on Si substrate. And, the existence of polarization is recognized by the hysteresis loop. The capacitor(MIM) structure of BaxSr1-xTiO3 thin film shows that the dielectric constant is increased as the mol% of Ba and the post-annealing temperature increase. MIS structure shows a increase of capacitance with increasing the mol% of Ba.
