Nursing teachers at elementary schools in Seoul were surveyed to determine their sources of information about oral health and their knowledge and attitudes about dental diseases and disease prevention. Questionaires were completed by 305 school nursing teachers. The questionaire included 8 items: demographic characteristics of the study population, sources of oral health information, reasons for maintaining good oral hygiene, ranking of methods of caries prevention in children, knowledge about fluorides, percieved effectiveness of fluorides for children, knowledge about periodontal disease, and the role of school nursing teachers in promoting oral health. Major findings are as follows: 1. The most frequently cited sources of information about dental health were continuing education courses(69.8％). 2. Most respondents had old concepts about the reasons for maintaining good oral hygiene. 3. Elementary school nursing teachers' knowledge about fluorides and preventive methods of caries and periodontal disease was found to be incomplete and sometimes inaccurate. 4. Respondents were likely to agree to accept roles that promote oral health except the supervising of fluoride mouthrinsing. Thus, it was considered that cooperation of all school members is necessary for improving oral health status by following fluoride mouthrinsing

This study was conducted to review the efficacy of different sources of stem cells in bone regeneration of cleft palate patients. The majority of previous studies focused on the transplantation of bone marrow mesenchymal stem cells. However, other sources of stem cells have also gained considerable attention, and dental stem cells have shown especially favorable outcomes. Additionally, approaches that apply the co-culture and co-transplantation of stem cells have shown promising results. The use of different types of stem cells, based on their accessibility and efficacy in bone regeneration, is a promising method in cleft palate bone regeneration. In this regard, dental stem cells may be an ideal choice due to their efficacy and accessibility. In conclusion, stem cells, despite the lengthy procedures required for culture and preparation, are a suitable alternative to conventional bone grafting techniques.

Objective: To assess oral cancer awareness, its associated factors and related sources of information among a selected group of Malaysians. Methods: A cross-sectional survey was conducted on all Malaysian ethnic groups aged ${\geq}15$ years old at eight strategically chosen shopping malls within a two week time period. Data were analysed using chi-square tests and multiple logistic regression. Significance level was set at ${\alpha}$ <0.05. Results: Most (84.2%) respondents had heard of oral cancer. Smoking was the most (92.4%) recognized high risk habit. Similar levels of awareness were seen for unhealed ulcers (57.3%) and red/white patches (58.0%) as signs of oral cancer. Age, gender, ethnicity, marital status, education, occupation and income were significantly associated with oral cancer awareness (p<0.05). Conclusions: There was a general lack of awareness regarding the risk habits, early signs and symptoms, and the benefits of detecting this disease at an early stage. Mass media and health campaigns were the main sources of information about oral cancer. In our Malaysian population, gender and age were significantly associated with the awareness of early signs and symptoms and prevention of oral cancer, respectively.

The most common and the most serious complication of the burn is infection, which is to a certain extent inevitable in the light of present knowledge and experience. From the burn wound as a rule there may be cultured at any given time the prevailing flora of the individual patient and of the hospital attendants and ward environ ment. Even without contamination from outside sources, organisms embedded in hair follicles and sweat glands survive the sterilizing effects of heat and serve as potential sources of localized and systemic infection. With necrotic tissue serving as nutrient material for pathogens there may occur, in succession, cellulitis, extending necrosis, lymphangitis and final septicemia. This is to report a case of osteomyelitis due to facial burn of 32 year old Korean male. The authors treated the patient by curettage and thin split thickness skin graft. The post operative course was uncomplicated and result was excellent.

Objectives: The study aimed to assess the form, reliability, and quality of information related to periodontal diseases shared on YouTube. Methods: On october 23, 2023, we conducted searches on YouTube using four keywords related to periodontal diseases. The searches retrieved a total of 394 videos from the first five pages for each keyword. Of these, 151 were included in the analysis. Videos were categorized based on the source and usefulness of the information, and their reliability and quality were assessed. Results: Analysis of the information sources revealed that medical websites or TV channels (45.7%) were the most prevalent, whereas commercial websites (2.0%) were the least prevalent. Videos uploaded by physician or hospitals (3.08±0.48) and medical websites or TV channels (3.01±0.94) demonstrated higher reliability. Videos categorized as having good and excellent quality were predominantly from physician or hospital sources (88.2%). Useful information related to periodontal diseases was available in 85.4% of videos, with physician or hospital sources contributing the highest proportion of useful information (52.7%). Conclusions: Videos from physician or hospital sources provide high-quality useful and reliable information. To ensure the provision of more useful and accurate information, the involvement and interest of experts are deemed essential.

There are increasing reports regarding regeneration of the defected tissues using tissue engineering technique. In this technique, multipotential stem cells are essential. There are many potential sources of adult stem cells, such as bone marrow, umbilical cord blood, fat, muscle, dental tissues and skin. Among them, skin is highly accessible and easily obtained with a minimum of donor site complications. Moreover, skin is an abundant adult stem cell sources and has the potential for self-replication and immune privilege. In this study, we isolated skin-derived precursor cells (SKPs) from the ear of adult miniature pigs. In these SKPs, the expression of transcriptional factors, Oct-4, Sox-2, and Nanog were detected by RT-PCR. In vitro osteogenesis and adipogenesis were observed at 3 weeks after transdifferentiations as assayed by positive von Kossa and Oil-red O staining, respectively. In addition, expression of osteocalcin and osteonectin in the osteogenic differentiation medium and $PPAR{\gamma}2$ and aP2 in the adipogenic differentiation medium were detected by RT-PCR. In vitro neurogenesis of porcine SKPs was observed during 24 and 72 hours after treatment of neurogenic differentiation medium. The results of this study suggest that SKPs demonstrate the properties of pluripotence or multipotence and multi-lineage differentiation. This indicates that autogenous SKPs are a reliable and useful source of adult stem cells for regenerative medicine.

During cancer progression, cancer cells are repeatedly exposed to metabolic stress conditions in a resource-limited environment which they must escape. Increasing evidence indicates the importance of nicotinamide adenine dinucleotide phosphate (NADPH) homeostasis in the survival of cancer cells under metabolic stress conditions, such as metabolic resource limitation and therapeutic intervention. NADPH is essential for scavenging of reactive oxygen species (ROS) mainly derived from oxidative phosphorylation required for ATP generation. Thus, metabolic reprogramming of NADPH homeostasis is an important step in cancer progression as well as in combinational therapeutic approaches. In mammalian, the pentose phosphate pathway (PPP) and one-carbon metabolism are major sources of NADPH production. In this review, we focus on the importance of glucose flux control towards PPP regulated by oncogenic pathways and the potential therein for metabolic targeting as a cancer therapy. We also summarize the role of Snail (Snai1), an important regulator of the epithelial mesenchymal transition (EMT), in controlling glucose flux towards PPP and thus potentiating cancer cell survival under oxidative and metabolic stress.

게임산업의 비중이 커지면서 질적으로나 양적으로 콘텐츠를 생산해 내는 기술력은 급속하게 발전을 거듭하고 있다. 그러나 콘텐츠를 구성하는 이야기가 점차 고갈되어가고 있다. 따라서 문화콘텐츠산업을 뒷받침할 수 있는 스토리를 발굴해내는 작업이 시급한 과제로 부상되고 있다. 우리 사회 저변에 게임이라는 콘텐츠가 정착된 이후, 긍정적인 인식보다 부정적인 인식이 강하게 부각되어 왔다. 본고에서는 이러한 부정적인 요인을 치유할 수 있는 방법을 스토리텔링에서 찾아보고자 한다. 여기에서 중요한 사실은 기술적인 요소로써의 공학적인 상상력과 서사적인 요소로써의 인문학적인 상상력의 융합의 문제다. 최근, 이야기의 발굴이 매우 중요시되고 있다. 본 논문에서는 문화 원형적 성격을 지니고 있는 구비문학이 게임 스토리텔링의 훌륭한 소재가 될 수 있다는 사실을 사례로 제시해 보았다.
