Purpose: Many topical agents had been used for contaminated wound treatment. Although antimicrobial ointments were widely used as topical agents, their comparative antibacterial and wound healing effects were largely unreported. The purpose of this study was to compare antibacterial effects and wound healing effects of common topical ointments on infected full thickness skin defect in the mouse. Methods: One full thickness skin defects in the mice (n=60) were developed on the back and left open for twenty-four hours. Sixty mice were divided into four groups: group B (dressing with Bactroban$^{(R)}$, n=15), group I (dressing with Iodosorb$^{(R)}$, n=15), group T (dressing with Terramycin$^{(R)}$, n=15), group G (control group, dressing with dry gauze, n=15). The size of wound defects and the grades of wound healing were evaluated at 4, 7, 10 days, and antibacterial effect was evaluated with restricted zone in Mueller Hinton agar by disk diffusion method. After the wound was left open for twenty-four hours, many Staphylococcus aureus was cultured. The wound defect size was decreased in order of Bactroban$^{(R)}$ (B), Iodosorb$^{(R)}$ (I), Terramycin$^{(R)}$ and gauze dressing group in all days, but difference among experimental groups was not statistically significant. The grade score of wound healing was increased in order of Bactroban$^{(R)}$, Iodosorb$^{(R)}$, Terramycin$^{(R)}$ and gauze dressing group, and the difference was statistically significant. Antibacterial effect for was increased in order of Bactroban$^{(R)}$, Iodosorb$^{(R)}$, Terramycin$^{(R)}$ and gauze dressing group, and the difference was statistically significant. Conclusion: Topical antimicrobial ointments application was effective against wound infections by S. aureus. Bactroban$^{(R)}$ may be an optimal topical treatment for infected wounds according to this study. However, further study is necessary to evaluate the clinical efficacy of antimicrobial ointments and to search for the mechanisms that explain their effects.

위에서 발생하는 MALT 림프종은 92% 이상에서 H. pylori 감염과 연관되어 있어 H. pylori의 제균요법이 일차 치료로 추천되고 있다. H. pylori 음성인 위의 MALT 림프종은 빈도가 낮고 병인 또한 밝혀진 바가 없어 아직까지 정립된 표준 치료는 없다. H. pylori 음성인 위의 MALT 림프종 환자 중, 병기 IE와 IIE 에서는 방사선 치료로 완전 관해에 이를 수 있다는 보고가 있다. 저자들 은 H. pylori 음성인 위의 MALT 림프종 환자에서 방사선 단독 치료만으로 11개월째 관해를 유지하고 있는 증례를 보고하는 바 이다. Most gastric MALT (mucosa associated lymphoid tissue) lymphomas are associated with Helicobacter pylori infection. Therefore, H. pylori eradication therapy is generally accepted first-line therapy for H. pylori-positive gastric MALT lymphoma. However, among the gastric MALT lymphoma, 5-10% patients have no evidence of H. pylori infection. There is no standard therapy for H. pylori-negative gastric MALT lymphoma. Currently, radiation therapy is the effective treatment for H. pylori-negative or antibiotic-resistant localized gastric MALT lymphoma. Herein, we describe a 65-year-old man with H. pylori-negative gastric MALT lymphoma who achieved complete remission by radiation monotherapy.

According to the advancement of display devices, the multi-screen contents display environment is growing to be accepted for the display exhibition area. The objectives of this research are to find communications technology and to design an editor interface of contents delivery system for the larger and adaptive multi-display workspaces. The proposed system can find existence of display devices and get information without any additional tools like marker, and can recognize device layout with only web-cam and image processing technology. The multi-display contents delivery system is composed of devices with three roles; display device, editor device, and fixed server. The editor device which has the role of main control uses UPnP technology to find existence and receive information of display devices. extract appointed color in captured picture using a tracking library to recognize the physical layout of display devices. After the device information and physical layout of display devices are connected, the content delivery system allows the display contents to be sent to the corresponding display devices through WebSocket technology. Also the experimental results show the possibility of our device connection and layout recognition techniques can be utilized for the large spaced and adaptive multi-display applications.

Purpose: The purpose of this study was to identify the dual mediation effect of depression and organizational commitment in the process of positive psychological capital affecting the turnover intention of navy personnel (commissioned officers/non-commissioned officers). Methods: This participants consisted of 196 navy personnel who served in warships. Data were analyzed using independent t-test, one-way ANOVA, Pearson correlation coefficient, and a bootstrap sampling method. Subjective questions were analyzed using content analysis methods to work out the context of navy personnel's job maintenance. Results: The dual mediation effect of depression and organizational commitment was confirmed in the process of positive psychological capital reaching turnover intention (total effect=-.961, p<.001). Conclusion: Based on the results of this study, it is necessary to develop an intervention program that utilizes internal factors to reduce turnover intention of navy personnel. Through this, it is expected that the internal factors of the navy personnel will be strengthened positively reducing the turnover intention and consequently leading to a decrease in turnover of navy personnel.

Objective:The present study investigated the clinical characteristics of Alzheimer’s disease (AD) dementia with low brain amyloid-beta (Aβ-AD) burden comparing with AD dementia with high amyloid-beta burden (Aβ+AD). We also developed a prediction model for the amyloid positivity on 11 C-labelled Pittsburgh Compound B (PiB) positron emission tomography (PET) with distinct clinical variables in AD dementia patients. Methods:Fifty-nine clinically defined AD dementia individuals, who participated in the Korean Brain Aging Study for Early diagnosis and prediction of AD (KBASE) study, were included. All the subjects received comprehensive clinical evaluations and PiB-PET. Based on cerebral PiB retention, all subjects were divided into Aβ+AD (n=47) and Aβ-AD (n=12) subgroups. To develop a prediction model for amyloid positivity, stepwise multiple logistic regression analysis was conducted. Results:When compared to Aβ+AD, Aβ-AD showed older age, later age-at-onset, and lower education. In regard of risk factors for dementia, Aβ-AD had higher frequency of hypertension and diabetes mellitus as well as lower frequency of apolipoprotein E (APOE) ε4 allele. Although there was no between group difference in Clinical Dementia Rating (CDR) or CDR sumof-boxes scores, mini-mental state examination and constructional recall scores were higher for Aβ-AD than Aβ+AD. The final amyloid positivity prediction model included APOE4 genotype, hypertension, and diabetes mellitus. Conclusion:The findings from this study indicated that clinically diagnosed AD dementia may have high possibility of not being pathological AD if they have older age and higher vascular risks, and did not have APOE4 genotype.

대학생들이 직업 선택에 대해 느끼는 어려움을 극복하고 사회에 잘 적응하도록 돕기 위해 진로와 관련한 연구들이 요구된다. 본 연구의 목적은 대학생의 자아존중감, 부모애착, 사회적 지지가 진로성숙도에 미치는 영향을 살펴보는 것이다. 이를 위하여 충청남도에 소재하는 대학교의 학생 총343명의 설문자료를 분석에 이용하였다. 자료 분석은 기술통계, 피어슨 상관관계, T-검증, F-검증, 그리고 다중회귀분석을 사용하였다. 연구결과는 다음과 같다. 첫째, 인구통계학적 변인(성별, 학년)에 따라 자아존중감, 부모애착, 사회적 지지와 진로성숙도에 차이가 있었다. 둘째, 자아존중감과 사회적 지지는 진로성숙도와 그리고 부모애착은 사회적 지지와 유의한 상관관계가 있었다. 마지막으로, 자아존중감과 사회적 지지는 진로성숙도에 영향을 미친 반면, 부모애착은 진로성숙도에 영향을 미치지 않았다. 본 연구결과를 바탕으로 대학생의 진로성숙도를 향상시킬 수 있는 프로그램과 상담적 개입방안 그리고 미래연구를 위한 제언을 담았다. Studies regarding career for university students is needed for them to overcome the difficulties of choosing the job and to help adjust well in this society. The purpose of this study was to identify the influences of the self-esteem, parent attachment and social support on the career maturity of university students. Subjects of the study were 343 students in university, located in Chuncheongnam-do. The data were analyzed by using descriptive statistics analysis, Pearson correlation analysis, t-test, F-test, and multiple regression analysis. The results of the study are as following. First, the result of the differences in self-esteem, parent attachment, social support, and the career maturity of university students by the demographic variable(gender, grades) were found. There were a significant correlation between four variables. Third, self-esteem and social support effects on career maturity, but not parent attachment. This study provided a data base for developing variety programs related on self-esteem, social support to university students. Implications, suggestions for future research were discussed.
