  • The purpose of this study was to investigate the effects of smoking on adult periodontitis after non-surgical periodontal therapy. The study population consisted of 40 patients with moderate to advanced periodontitis. Smokers(n=20) were defined as individuals smoking at least twenty cigarettes per day at the time of the initial examination. The non-smoking group(n=20) consisted of individuals who were not smoking at the initial examination. The average age was 42.4 years for the smoking and non-smoking group. Examination regarding plaque index, gingival index, pocket depth and contrast phase microscope were performed. Evaluation were made at the first, the second and the fourth weeks after periodontal non-surgical therapy. The results were as follows: 1. Clinical indices including plaque index, gingival index, and pocket depth were decreased in both smoking and non-smoking group at the first, the second, and the fourth weeks. Especially, clinical indices of non-smokers were more significantly decreased than those of smokers. 2. Non-motile rods were increased and motile rods were reduced at the fourth week. spirochetes were reduced significantly in the non-smoking group at the fourth week. These results suggest that smoking play a minor role in adult periodontitis after non-surgical periodontal therapy.

  • Contrast-enhanced MR angiography has become a widely used method useful for clinical diagnosis. Early studies identified a number of technical issues, and many of these have been addressed with various MRI physics innovations over the last several years. The quality of the results is high enough that CE MRA is replacing conventional x-ray angiography methods at many institutions. Ongoing research is expected to provide further improvements in performance, most notably in additional reductions in examination time, in time-resolved 3D imaging, and in improved imaging of the peripheral vasculature with extended fields of view.

  • This study was performed in order to evaluate the accuracy and the usefulness of the cytology of crush preparation in central nervous system (CNS) lesions. Forty four intraoperative biopsies were performed at the time of craniotomy including 34 benign and 10 malignant lesions. Crush preparations were prepared from tiny tissue fragments of craniotomy products. All cases were stained with toluidine blue. Intraoperative diagnoses made on cytologic examination were compared with the final paraffin section diagnoses. Comparison between the results of the cytologic and histologic findings revealed an overall diagnostic accuracy of 88.6%. This study attests to the diagnostic accuracy of cytologic examination in CNS lesions. The detailed cytologic features are described and important criteria for the cytodiagnosis of CNS lesions are discussed. This review leads us to think that cytologic examination by crush preparation in CNS lesions is considered as a simple, safe and highly diagnostically accurate method.

  • Ultrasonographic examination of the stifle joint four clinically and radiographically normal adult dogs was performed before and after inducing the cranial cruciate ligament (CrCL) rupture of the bilateral stifle surgically. At Pre- or post-surgery, the hyperechoic patella ligament and the echogenic infrapatella fat interfered the visualization of the CrCL by the plain scanning method. However when the stifle joint was imaged by the scanning method injecting normal saline within the joint capsule, the hyperechogenic ligament was visualized by the separation of the infrapatella fat and the CrCL and the contrast effect of anechoic saline. When the stifle joint was imaged by the real time scanning method after the induction of the surgical rupture, fluttering of the ligament and anechoic area between the bone and the CrCL was identified due to the lack of tonicity and continuity of the ligament. Enlargement of the ligament because of its increased diameter as well as fluttering of the CrCL and the increased joint space's thickness was visualized. Consequently, confirming fluttering of the CrCL, increased ligament diameter and anechoic region between the CrCL and the bone, ultrasonographic examination is a valuable diagnostic tool as well as cranial drawer test and radiographic examination.

  • Purpose: This study was carried out to understand the in-patients' experiences related on informed consent for examination, treatment or surgery. Method: The study was conducted with 578 patients who were admitted to the departments of internal medicine and surgery for examination, treatment or surgery requiring informed consent from November 1 to 30, 2004 at three general hospitals in Daegu, Busan and Gyeongsangbuk-do. The data was analyzed by using SPSS 11.5 for Windows. Results: Although the one who explains during the process of informed consent should be doctors, 6.6% was informed by nurses or others. In addition, the majority has been told for complications and risk while relatively fewer patients were informed for necessity, method and costs of the procedure, and no one ever heard of other alternatives or the right to terminate the procedure at any time. While 40% of patients were not the final decision-makers of examination, treatment or surgery, 11.9% of patients answered their opinions were not considered during the final decision-making process. Conclusion: The study suggest that the ethically appropriate informed consent has not been achieved in the clinical practice, and therefore it is necessary to develop the specific behavioral guidelines and nursing ethics education program for nurses in order to settle down the desirable informed consent at the dimension of nursing management.

  • The vacuum evaporated Au films on soda-lime glasses were measured by the electrical conductivity with the variation of the annealing time, relative humidity, and temperature. Au films structures were observed by scanning Electron Microscope and X-ray Diffractometer. As the annealing time and temperature increased, the electrical conductivity was increased due to the migration or annihilation of defects, but the electrical conductivity was decreased as with the relative humidity increased. Au films by XRD and SEM examination showed the negligible effect of chemical reactions.

  • The purpose of this study was to examine the status of coffee intake in South Korea by analyzing the 4th Korea National Health and Nutrition Examination Survey. The results showed that 52.3% of Koreans consumed coffee at least once a day. Males consumed coffee more frequently than females and those aged 20-39 years and 40-59 years consumed coffee most frequently. Coffee drinkers consumed coffee two times a day and 138 mL each time on average. Coffee was mainly consumed either at home (44.8%) or in the workplace (36.1%); males drank coffee most frequently in the workplace and females did so at home. Milk coffee including coffee from vending machines and coffee mix (73.8%) was the most common type of coffee consumed. The results of this study would extend the understanding of the general status of coffee intake in South Korea, which has shown steady growth but remains a relatively overlooked research area.

  • Objectives: This study aims to compare the contents of physical activity questions of Korean National Health and Nutrition Examination Survey(KNHANES), and to propose suggestions for improvement. Methods: Questions measuring physical activity prevalence of adults in the KNHANES from KNHANES I(1998) to the first year of KNHANES V(2010) were compared. Results: The questions used in each survey showed some problems in consistency and appropriateness. Major issues identified are as follows. First, the questions in each survey were not consistent, and would be inappropriate to make time series comparisons. Second, the purpose of physical activity was not clear. Third, the examples of physical activities suggested in the questions were not appropriate. Fourth, the intensity of physical activity were not adequately described. Fifth, by excluding walking from the moderate-intensity physical activity category, the prevalence of moderate-intensity physical activity could be underestimated. Sixth, it is difficult to measure the total amount of physical activity performed in one day because answers from the other domains cannot be clearly differentiated. Conclusions: The physical activity questions in the KNHANES questionnaire should be improved so that they are consistent with the purpose of survey, the respondents can easily understand the contents of the questions, and the questions can measure all physical activity performed in the different domains.
