The purpose of this study was to analyze the association among high school students' self-efficacy, self-resilience, and oral health promotion lifestyle, identify relevant factors, and provide basic data for oral health promotion programs. The subjects of this study were 287 students, research tool was the structured, anonymous, self-administrated questionnaire. The data were analyzed by SPSSWIN 18.0, Pearson correlation and Hierarchial multiple regression et al. Significant positive correlation was found between self-efficacy and self-resilience and between self-efficacy and oral health promotion lifestyle and positive correlation was also found between self-resilience and oral health promotion lifestyle. Mother's education, past oral health behavior, self-efficacy, and self-resilience affected oral health promotion lifestyle, with the explanatory power of 32.3%. Since self-efficacy and self-resilience are correlated with oral health promotion lifestyle, it is necessary to develop a plan for activating oral health education with the objective of improving the combination of these factors.

The purpose of this study is to provide substantial foundation to establish effective sex education plan for female college students. For this purpose, we compared female college students with health related majors and the ones with non-health related majors in knowledge in sex, attitude toward sex, and sexual experience. We took the form of self-recording to survey 269 single female college students. The result is as follows. For knowledge in sex, including reproductive organs, contraception, delivery, sexual disease, and sexual intercourse, students with health-related majors(20.59) gained higher scores than students with non-health related majors(16.82). Scores for attitude toward sex indicated 2.43 for the health related majors and 2.35 for the non-health related majors. Attitude toward pre-marital sex, sex admissibility, and abortion showed especially distinct result between the two groups. Whether a student has ever engaged in sexual intercourse served as a significant variable to determine knowledge in sex overall, and the indexes such as sexual pleasure, chasteness, marital values, and attitude towards sex indicated significant differences. The result may be interpreted that the students with sexual experience tend to show more open attitude toward sex. The result indicated that contraception, pregnancy, and delivery were the parts that the participants most wanted to be educated on. Knowledge in sex is both positively correlated with attitude toward sex and sexual behavior. Also, the result indicates that knowledge in sex, both subjective and objective, significantly affects sexual behavior.
Periodontal ligament (PDL) is the connective tissue located between the tooth root and alveolar bone. In a previous study, PDLs22 was isolated as a PDL-specific gene by using subtractive hybrid-ization between cultured PDL fibroblasts and gingival fibroblasts. It was also suggested that PDLs22 plays important roles in the development, differentiation and maintenance of periodontal tissues. However, little is known about functional study of PDLs22 using recombinant protein in PDL fibroblast differentiation and periodontium formation. In this study, in order to produce the PDLs22 recombinat protein, PDLs22 expression vector were constructed and expressed its protein in various host cell and temperature conditions. The results were as follows: 1. PDLs22 protein was not strongly expressed In the induction system using pRSET-PDLs22 construct. 2. When the BL21(DE3) pLysS was used as a expression host, PDLS22 protein was strongly ex-pressed in the induction system using pHCEIIBNd-PDLs22 construct. 3. The PDLs22 protein was recognized at a molecular weight of 28 kDa in western blots. 4. Almost of the expressed PDLs22 protein was not soluble and observed like as inclusion body. 5. The protein solubility was not improved after modification of induction time and temperature during PDLs22 protein production. In this study, the system for the PDLs22 protein production was connstructed. However, the re-results suggest that further studies will be needed to produce the considerable amount of PDLs22 re-combinat protein, which can use for the periodontal regeneration.
The purpose of this study explained the experience of volunteering activities and the relationship of subjective self-awareness in order to examine the social meaning of volunteer activities. For adults aged 20 or older, 312 volunteering experience and social support awareness were analyzed on the level of self-identity by allocation sampling method depending on gender and age. The analysis results of this study were as follows. First, it was found that those who have experienced volunteer activitiies have a relatively simple willingness to participate in professional volunteer activities and those who have experienced volunteer activities. Second, social support and self-identification were different depending on whether they have experienced volunteer activities. Third, age, volunteer participation, willingness to participated in volunteering, and social support were analyzed as explanatory factors predicting self-identification of research participants. Based on the research results, volunteer activities to positively promote self-awareness suggested the need to practice volunteer activities according to the life cycle so that social meaning can be given. As a policy suggestion, the need for volunteer activities was closely analyzed to enable healthy self-forming for well-aging from adulthood to old age to discussed the need for policies and systems to strengthen volunteer motivation as leisure activities.

For the more, simpler design and softer texture of device prmoted cooperation of patients during use. This case report is to present the satisfactory results gained by using $T4K^{TM}$ on Class II patients. Comment 1. $T4K^{TM}$ was applied in Class II malocclusion patients of mixed dentition with expected space insufficient to gain facial improvement. 2. Excessive overjet, overbite were improved. 3. Main effects are regarded to have been achieved by development of lingual slant of upper jaw, labial slant of lower jaw, and lower part of jawbone. 4. Bad habits, such as mouth breathing, can also be adjusted.
The purpose of this study was to offer basic data for developing effective program for promotion elderly people's oral condition, and oral health behavior upon the appearance of denture. This study was performed by utilizing health questionnaire survey and oral examination survey for first year(2010) law data of the 5th korea national health and nutrition examination survey. The research subjects were 1419 people who were aged over 65 and completed the oral examination and oral questionnaire survey. In the general characteristics, the need of denture was indicated highly in the male elderly. Factors of having relationship with a need of denture in oral health condition were indicated to be chewing difficulty(p<0.001) and dental caries(p<0.0001). The case of not using oral hygiene device was high in a need of denture(p<0.001). Also, a case of not dental treatment was indicated to be high in a need of denture(p<0.001). Through these related findings, the elderly's oral condition and oral health behavior were indicated to have high relationship with a need of denture. There is a need of securing basic data for promoting the elderly's oral health in the future and of seeking a plane for application in order to improve the elderly's health in the aging society. Therefore there is a need of securing and seeking elderly's health program which is considered the aging society's characteristics to improve the elderly's health promotion.

This study investigated the oral health knowledge and educational needs of adults by life cycle. We aimed to provide basic data for developing oral health education plans for well -aging. The survey was conducted online and through mobiles by Gallup Korea during February 2021. A total of 319 adults over the age of 19 were surveyed. The study aimed at investigating the general characteristics, the quality of life-related to oral health, knowledge of oral health, and the need for well-aging education. The PASW Statistics ver 18.0 statistical program was used for data analysis. The analysis of the data suggests that prevention was the highest priority among all age groups. Furthermore, there was a difference in the perceived educational need among different age groups. The cause of the youth, the treatment of the middle-aged and the elderly were significantly related to oral and systemic disease. The need for education related to oral diseases was ranked in the order of aches, bad breath, periodontal diseases, and tooth discoloration. For information, the subjects reached out to the internet, dental and medical institutions, and public health centers. The teaching methods experienced by those surveyed included lectures combined with experience, videos, and expert lectures. We believe that this study can be used to develop an education plan that reflects the needs of the subjects when conducting life cycle education for well-aging.
Granular gland regeneration in the toad after dorsal skin wound histologically was examined using scanning and transmission electron microscopy. After cutaneous wounds were induced by excision, animals were maintained in special cages for up to 20 days. In transmission electron microscopy (TEM), newly formed granular gland, though poorly developed, was seen on 4 day after injury. Epithelial cells moved toward apical region of newly formed gland. The cells had smooth surface and were not connected to other cells by desmosomes. Mitochondria rich cell (MRC) possessing long cytoplasmic processes formed a gland cavity and hemidesmosomes were found under the cell processes. Basal cavity of newly formed gland consisted of MRC, pro-granular producing cells (pGPC), and granular producing cell (GPC). Moreover it was observed that xanthophores moved to the base of the epithelial tissue on 10 day after the injury. These cells contained numerous pterinosomes and carotenoid vesicles. Immature pterinosomes were large and carotenoid vesicles were moderately electron dense. On 13 day after the injury, xanthophores contained abundant carotinoid vesicles and lammelated pterinosomes. Iridophores were also observed adjacent the developing xanthophores on 16 day post-injury. These observations indicated that regeneration of granular gland from glandular precursor cells during wound healing and subsequent expansion of the glandular cells might be dependent on maturation and proliferation of these newly formed cells.

The purpose of this study is to identify characteristics of well-aging related research conducted in Korea and to analyze the concept definition to present the direction for future well-aging research in Korea. As a research method, an integrated literature review suggested by Whittemore & Knafl was conducted. Study results found research conducted in Korea consisted of 2 literature reviews, case studies, qualitative studies, 3 survey studies, and 2 experimental studies. In addition, there were 3 studies performed prior to 2017 and 8 studies after that included 2 dissertations and 9 dissertations in academic journals. The definition of well aging consisted of physical, emotional, social, economic, and self-realization aspects. Based on the results of this study, it is necessary to provide education and programs according to life cycles to prepare well aging, and in the future, well-aging studies should be conducted in various academic fields.
Purpose: Avulsed tooth can be completely recovered, if sound periodontal ligament (PDL) of tooth is maintained. Although a lot of storage solutions have been explored for the better storage of avulsed tooth, there is a shortcoming that the preservation time is much short. On the other hand, there has been studies that (-)-epigallocatechin-3-gallate (EGCG), the most abundant polyphenol in green tea, which is related to the anti inflammatory, antioxygenic, and antibacterial effects, allows the successful preservations of tissues and cells. This study evaluated the effect of EGCG on avulsed-teeth preservation of Beagle dogs for a period of time. Methods: The atraumatically extracted teeth of Beagle dogs were washed and preserved with 0/10/$100\;{\mu}M$ of EGCG at the time of immediate, period 1 (4 days in EGCG-contained media and additional 1 day in EGCG-free media), period 2 (8 days in EGCG-contained media and additional 2 days in EGCG-free media) and period 3 (12 days in EGCG-contained media and additional 2 days in EGCG-free media). Then, the cell viabilities of preserved teeth was calculated by dividing optical density (OD) of 3-(4,5-Dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay with OD of eosin assay to eliminate the measurement errors caused by the different tissue volumes. Results: From the results, the immediately analyzed group presented the highest cell viability, and the rate of living cells on teeth surface decreased dependent on the preservation period. However, the $100\;{\mu}M$ of EGCG-treated group showed statistically significant positive cell activity than EGCG-free groups throughout preservation periods. Conclusions: Our findings showed that $100\;{\mu}M$ EGCG could maintain PDL cell viability of extracted tooth. These results suggest that although EGCG could not be a perfect additive for tooth preservation, it is able to postpone the period of tooth storage. However, further in-depth studies are required for more plausible use of EGCG.
