Objectives: The purpose of this study is to analyze the oral health knowledge among workers at nursing homes, and needs to educate them on elderly oral care. Methods: A self-reported questionnaire was filled out by 241 workers at nursing homes in Gwangju and Jeonnam, Korea from May to June, 2016. The data were analyzed with the SPSS 19.0 program for independent t-test or one-way ANOVA analysis. Results: The data analysis showed that workers at nursing homes had lower knowledge about periodontal diseases (65.1%) than about denture management (78.5%). The knowledge of periodontal disease and denture management of workers with experience of oral care education for elderly was significantly higher than that of non-experienced ones (p<0.01). On the question whether those workers should get oral health care education is necessary or not, respondents answered positively (They scored 4.10 points on the 5-point Likert scale from 1 point - Not at all to 5 points - definitely yes). Conclusions: It is necessary to provide elderly oral care education to workers at nursing homes. Furthermore, oral health professionals should be deployed for systematic and practical oral care for elderly.

The purpose of this research is to analyze the location requirments of Artillery firing range. To this end, we selected several representative firing range and analyzed their capability and constraint. We considered not only the conventional ammunitions, but also state-of-art ammunitions such as a 155㎜ hybrid ammunition and new Multiple Launched Rocket System ammunition. Based on the analysis result, we could derive essential requirements for the long-distance fire range. But in reality, there are so many limitations to construct an artillery firing range in South Korea. This is attributed to the fact that many local residents oppose strenuously due to the potential hazard of artillery shell such as noise, accidental firing, decrease of land price. Thus, we can arrive at a conclusion that it is virtually impossible to satisfy all requirements for the optimal firing range for the long-distance fire training due to the budget for purchase of safety area and compensation for residents. Thus we propose alternative ways such as a naval firing range or mobile harbor type firing range by using Jack-up barges.

Intracellular reactive oxygen species(ROS) produced in a various pathologic state was known to intermediate many cellular response such as inflammation. Recently, low level light irradiation by HeNe laser used in many clinical field could improve inflammatory state by scavenging intracellular ROS through photo-detachment/dissociation process. The purpose of this study is to investigate the differential effects of blue and red light irradiation on ROS scavenging effects. Immortalized human oral keratinocyte HaCat cells were used. Phorbol 12-myristate 13-acetate(PMA) was treated for inflammation. Red(635nm) and blue(470nm) light irradiation was carried out. To asses the intracellular ROS by light irradiation, confocal microscopic and flow cytometric assay with DCF fluorescence for total ROS and ESR spectrometry of DMPO-O2 - for superoxide anion were caried out. And microarray was performed for mRNA expression level. Released intracellular total ROS in PMA treated HaCat cell lines was dissociated efficiently by red light irradiation, while blue light irradiation did not. Rather, blue light irradiation increased ROS formation. For superoxide anion generated the first synthetic form of ROS, red light irradiation reduced its amount but blue light irradiation did not. In the mRNA expression in line with cyclooxygenase(COX) pathway, prostagrandin endoperoxide synthase 1(PTGS 1), prostagrandin endoperoxide synthase 2(PTGS 2) and phospholipase A2(PLA2) were increased by both light irradiation and they were decreased as time flows. And genes associated with ROS releasing, mRNA expressions of tumor necrosis factor receptor (TNFR) and interleukin 1beta(IL1B) were increased by 1 hour red light irradiation but did not by blue light irradiation. As a result, red and blue light irradiation showed different response in affecting the level of ROS. These findings indicate that red light rather than blue light is more useful for anti-inflammation in clinical field

Ameloblastic fibro-odontoma has been defined as a lesion similar to ameloblastic fibroma by WHO, as it shows inductive changes which forms enamel and dentin. Ameloblastic fibro-odontoma is a very rare mixed dentition tumor in children, and the symptom shows indolent edema in maxillary and mandibular molar area. The prevalence is two times higher in male than in female, and two times higher in maxilla than in mandible. Radiologically, it shows clear border and characteristics of both fibroma and odontoma histologically. This review reports a case that a 4-year old female visited in dental clinic of this school for edema as chief complaint in Feb, 2012. Emergency surgical curettage was performed right after initial diagnosis as odontoma, then confirmed diagnosis as Ameloblastic fibro- odontoma after biopsy. Currently, after 6 month, no sign of recurrence can be seen. Ameloblastic fibro-odontoma is very rare mixed dentition tumor. Moreover, as it is the case of female maxilla, this case is worth of publishing. Furthermore, accurate diagnosis of Ameloblastic fibro-odontoma is difficult. This review is published for accurate diagnosis through differential diagnosis of several important mixed dentition tumors.

A Warthin’s tumor of major salivary glands, in particular of parotid glands, is a common benign tumor that may occur synchronously or metachronously in the same or contralateral gland. Moreover, epithelial malignance associated with a Warthin’s tumor is extremely rare, and exists in three forms; epidermoid carcinoma, adenocarcinoma, and undifferentiated carcinoma. The reports, related with a case of squamous cell carcinoma arising in a Warthin’s tumor at the parotid gland were reported only additional 3 cases from 1999 to 2010; 30 cases reported up to 1999.[2,4,7] This case report was a extremely rare case where both a primary squamous cell carcinoma and a Warthin's tumor were coexisting in the same
