Park*, Eui‐,Chul,Yoon, Jong‐,Bok,Seong*, Jin‐,Sil,Choi, Kyoung‐,Soo,Kong, Eung‐,Sik,Kim, Yun‐,Jeong,Park, Young‐,Mee,Park, Eun‐,Mi Taylor Francis 2006 Preparative biochemistry & biotechnology Vol.36 No.1
<P>Reactive oxygen species (ROS), generated by ionizing radiation, has been implicated in its effect on living tissues. We confirmed the changes in the oxidative stress markers upon irradiation. We characterized the changes in the proteome profile in rat liver after administering irradiation, and the affected proteins were identified by MALDI-TOF-MS and ESI-MS/MS. The identified proteins represent diverse sets of proteins participating in the cellular metabolism. Our results demonstrated that proteomics analysis is a useful method for characterization of a global proteome change caused by ionizing radiation to unravel the molecular mechanisms involved in the cellular responses to ionizing radiation.</P>

Kyoung Sik Park,Kyu Eun Lee,Do Hoon Ku,Su-Jin Kim,Won Seo Park2,Hoon Yub Kim3,,Mi Ra Kwon1,Yeo-Kyu Youn1 대한외과학회 2013 Annals of Surgical Treatment and Research(ASRT) Vol.84 No.6
Purpose: To evaluate the antiadhesive effects and safety of an oxidized regenerated cellulose (Interceed) after thyroidectomy. Methods: Seventy-six thyroidectomized patients were prospectively randomized into two groups with regard to the use of Interceed. We evaluated each group for their adhesive symptoms using four subjective and four objective items at the 2nd week, 3rd and 6th month after thyroidectomy. All patients were examined for vocal cord motility by indirect laryngoscope at each period. Results: Total adhesion scores at each postoperative follow-up period decreased with time, but were not significantly different in each group. The median score for swallowing discomfort for liquid was significantly lower in the Interceed group than in the control group 2 weeks after surgery. In addition, the severity of skin adhesion to the trachea was reduced in the Interceed group compared with the control group 6 months after surgery. During the study, there were no adverse effects or significant differences in postoperative complications between the groups. Conclusion: Interceed appeared to be safe and effective in improving neck discomfort at early postoperative periods and preventing skin adhesion to the trachea 6 months after thyroidectomy.

This study attempted to determine the effects of hair protection by investigating the characteristics and possibilities of hair cosmetics using the hot water extracts of Syzygium aromaticum and then hair-protection effects were confirmed through pre-treatment and post-treatment at consecutive chemical treatments. At the consecutive chemical treatments, the general treatment was divided into pretreatment(N1) and general treatment post-process(N2). Then, the Syzygium aromaticum-based treatment was divided into pre-treatment(J1) and post processing(J2). According to the analysis, tensile strength was the highest in the Syzygium aromaticum extract treatment group. At consecutive treatments, ‘J2’ which processed treatment for Syzygium aromaticum, was the highest. In terms of hair thickness, the Syzygium aromaticum group was greater than the general treatment group. When measured to determine the morphological characteristics of ‘Hair’ at 20,000 magnifications using SEM, the Syzygium aromaticum extract post-treatment group (J2) revealed the highest value (373.98±10.83㎚). Regarding hair composition under the EDS, Syzygium aromaticum extract post-treatment group was the highest with 07.77% interms of sulfur content. The results confirmed that Syzygium aromaticum extract treatment is extremely effective in easing hair damage which is caused by consecutive dyeing after permanent. Therefore, the Syzygium aromaticum extract treatment would be effective in preventing hair damage and keeping hair healthy and glossy.

The purpose of this study is to survey about the changes of the resident's behavior and psychology after house's opening of fence project in Seoul. This research attempts to evaluate the people through a view of physical, psychological and social way. The method of evaluation used a field investigation, an interview and a checklist that was made from related references. The result of this study, the residential satisfaction has slightly improved after opening of fence. Especially the people could reduce the stress of parking. But the people have a serious anxiety that concerns with privacy and crime prevention because of the indefinite area. On the other hand, the change of the people's behavior and psychology about the area of defence has extended from their garden to neighbour and the street of the area.

In this paper, we have proposed an effective moving objects tracking method based on the motion information in the video sequence. First, we extract the moving objects using the processes of morphological dilation and differential image in the video sequence and then we extract the motion information utilizing the location and orientation of the moving objects in the subsequent images. The motion information is extracted using various statistical measurements, extracting the high-level features from the regions of pixels in the images. The measurements, such a s area, length, perimeter, orientation, elongation, compactness, moments of inertia, are used as the statistical and geometrical descriptors. The principle axes of an object on this features gives the local direction of the object, while the center of gravity gives the center position of the object. The angle between two principal axes of the moving objects in the consecutive images gives the geometrical direction of the moving object, while the displacement of the center of gravity, gives the distance covered by the moving objects. So we have extracted the global motion information using the principal axes and center of gravity. The simulation results on the test images are very good, where either the motion is very slow, or the frame rate is very high.

Background: With reports on the relation between smoking and depression appearing since 1980, it has become clear that depression is one of the psychodynamics of smoking, though there has been little or no progress made in the study of whether or not there is indeed a relation between depression and nicotine dependence. Purpose: The purpose of the study was to investigate the effects of depression on the amount and period of smoking and nicotine dependence among university man student smokers. Method: In periodical examination between 14 and 21, May, 2003, using 170 university male. The CES-D(Center for Epidemiologic Studies Depression) Scale and the FTQ(Fagerstrom Tolerance Qustionnaire) were utilized to measure the level of depression and nicotine dependency. The amount of smoking was calculated based on the number of cigarette used. Result: Results indicated that depression had something to do with amount of smoking. Nicotine dependence also was related to depression but total value was relatively low. finally the period of smoking had nothing to do with depression. Conclusion: The results of this study revealed that the amount of smoking of university man student smokers was very high. Both the amount of smoking and nicotine dependence were affected by levels of depression. Accordingly psychiatric nursing access such as emotional support is needed to manage depression and decrease smoking.
