  • This study explored an alternative activity for the assessment of young children's literacy in Korea; namely, the evaluation of children's ability to construct meaning independent of decoding skill. The subjects were 78 children 4 to 5 years of age in Seoul. Instruments were the researcher's revised form of the Story Construction from a Picture Book, TRSR (Teachers' Ratings of Students' Reading) designed by van Kraayenoord & Paris (1996), and the revised form of the WLAT (Written Language Awareness Test, Kim, 1995). The assessment scores and oral responses of the children were analyzed by Pearson's r, MANOVA and one-way ANOVA, using repeated measures. The findings showed that (1) the story construction total scores were significantly correlated with WALT scores and the subcategory scores were intercorrelated with each other. (2) The story construction total scores differed by age, and (3) the 2 phase scores were higher than the 1 phase scores.

  • These days, the clinical course of dental imaging sector has done a lot of implant-related imaging courses, including cone beam CT. In contrast, the general image reading course is not given a lot of opportunities to learn. Therefore, it is imperative that we talk about the general image interpretation that can be read easily applied in a dental clinic. When we see a strange radiographic finding of our patient in the dental clinic, we should first check whether the radiographic finding is a normal finding or a morbidity. If the finding is diagnosed as a morbidity, you should make plans for the appropriate therapy. The most important step is classification between normal state and morbidity. Some lesions may occur without any clinical symptoms. Therefore, we should read all the parts of radiographs, even the patient does not have clinical symptoms.

  • Purpose: The aim of this study was to assess the ex vivo diagnostic ability of 9 different cone-beam computed tomography (CBCT) settings in the detection of recurrent caries under amalgam restorations in primary teeth. Materials and Methods: Fifty-two primary teeth were used. Twenty-six teeth had dentine caries and 26 teeth did not have dentine caries. Black class II cavities were prepared and restored with amalgam. In the 26 carious teeth, recurrent caries were left under restorations. The other 26 intact teeth that did not have caries served as controls. Teeth were imaged using a $100{\times}90-mm$ field of view and a 0.2-mm voxel size with 9 different CBCT settings. Four observers assessed the images using a 5-point scale. Kappa values were calculated to assess observer agreement. CBCT settings were compared with the gold standard using a receiver operating characteristic analysis. The area under the curve (AUC) values for each setting were compared using the chi-square test, with a significance level of ${\alpha}=.05$. Results: Intraobserver kappa values ranged from 0.366 to 0.664 for observer 1, from 0.311 to 0.447 for observer 2, from 0.597 to 1.000 for observer 3, and from 0.869 to 1 for observer 4. Furthermore, interobserver kappa values among the observers ranged from 0.133 to 0.814 for the first reading and from 0.197 to 0.805 for the second reading. The highest AUC values were found for setting 5 (0.5916) and setting 3 (0.5886), and were not found to be statistically significant(P>.05). Conclusion: Variations in tube voltage and tube current did not affect the detection of recurrent caries under amalgam restorations in primary teeth.

  • This study examines the effect of oral narration learning for children's forest fairy tales on self-emotional regulation and community spirit cultivation. To achieve this aim, experiments were conducted involving 40 children in S city during 16 sessions over a period of 8 weeks. Findings showed that the experimental group with oral narration learning regarding forest fairy tales was higher than the control group, confirming the usefulness of oral narration learning for forest fairy tales. In particular, the experimental group was higher than the control group in basic lifestyle, community spirit, sociality development and self-awareness of community spirit factors. In other words, children can focus their attention on fairy tales by reading, listening and directly experiencing fairy tale materials in nature as communication with nature in forest experience activities, and can collaborate with peers based on their emotional connection with nature. Their ability to practice principles and order as well as to improve relationships with peers and increase self-emotional regulation is enhanced through experience with fairy tale stories. Such results imply that the utilization of forest fairy tales needs to be enhanced, as forest fairy tale-linked activities have a positive educational effect on community spirit cultivation as well as self-emotional regulation.

  • Fluorine is an element that promotes dental caries preventive effect at proper concentration level, but may have significantly undesirable impact on dental caries if correct information of fluorine is not recognized. Therefore, this study is intended to evaluate fluorine awareness among the adults in their 20s and analyze oral health conditions based on such awareness in order to promote dental caries preventive effect and convey correct knowledge of fluorine. For this study, 82 adult men and 102 adult women in their 20s, all of whom lived in Daegu, Gyeongsangbuk-do, were surveyed from May 1, 2014 to June 30 of the same year, along with oral health examination to evaluate their oral health conditions. The results of the analysis showed that 19.46% of respondents answered "No" to the question related to awareness towards the use of fluorine in DT rate dental clinic based on the degree of fluorine awareness, which was higher than 11.10% who answered "Yes"(p<.05). Moreover, 18.32%of respondents answered "No" to the question related to whether they were checking the label indicating the fluorine content in product, which was the highest rate, suggesting that the rate was higher when there was stronger tendency to avoid reading the precaution notice (p<.05). In addition, 71.98% of respondents answered "Yes" to the question associated with the awareness to the use of fluorine in FT rate dental clinic based on the fluorine awareness, which was higher than 49.04% of respondents who answered "No" (p<.05). This study is meaningful in that it provides basic data for the implementation of fluorine prevention projects in the period ahead by determining the effect of fluorine awareness on oral health conditions. Based on aforesaid results, both educational and promotional activities need to be carried out vigorously to help raise fluorine awareness.

  • The Purposes of this study are to determine differences of body temperature between Right arid left subligual areas itself and differences depending upon the utilization rate of mastication according to time intervals and to determine the length of time necessary for temperature taking. This Experiment was conducted from Oct 6 through Oct 11, 1975. in which accurately tested clinical Centigrade Thermometers have been utilized. Two thermometers were inserted simultaneously under the right and left sublingual areas and the mouth kept closed while thermometers were in Place. Temperature readings were dr no at three minutes, five minutes and ten minutes. These procedures were repeated one hundred times to different subjects and the data were analyzed statistically by means of the t-test and the F-ratio. Under the 10 hypotheses designed for this study, The findings obtained are as follows; 1. The body temperatures taken at 3, 5, 10minutes intervals in the left sublingual areas were significantly higher than in the right sublingual areas , The average differences of body temperature between the right and left sublingual areas were 0.09$^{\circ}C$, 0.05$^{\circ}C$ and 0.03$^{\circ}C$ in the oder of time interval of 3, 5, and 10 minutes. 2. The body temperatures taken in the right sublingual areas among three different temperature readings, 3, 5 and 10 minutes were significantly different in 57 subjects who have been utilizing evenly both sides of the Teeth. The average readings in a group taking for 3 minutes was 37.04$^{\circ}C$, for 5 minutes 37.15$^{\circ}C$ and for 10minutes 37.28$^{\circ}C$. 3. The body temperatures taken in the left sublingual areas among three different temperature readings, 3, 5 and 10 minutes were significantly different in 57 subjects who have been utilizing evenly both sides of the tenth. The average reading in a group taking for 3 minutes was 37.13$^{\circ}C$, for 5 minutes 37.2$^{\circ}C$ and for 10 minutes 37.31$^{\circ}C$. 4., Oral temperatures taken at 3, 5, 10 minutes intervals at the side of mouth utilized for more frequent mastication were Significantly higher than the other side. The average differences of body temperature between more frequently utilized side and Less frequently utilized side were 0.08f, 0.08f and 0.09f in the order of time interval of 3, 5 and 10 minutes. 5. Oral temperature taken at the side of mouth more frequently utilized for mastication among three different temperature readings, 3, 5 and 10 minutes were significantly different in 43 subjects who have been unequally utilizing either side of teeth. The average reading in a group taking for 3 minutes was 37.09$^{\circ}C$, for 5 minutes 37.17$^{\circ}C$ and for 10 minutes 37.3$^{\circ}C$. 6. Oral temperature taken at the side of mouth less frequently utilized for mastication among three different temperature readings 3, 5 and 10 minutes were significantly different in 43 subjects who have been unequally utilizing either side of teeth. The average reading in a group taking for 3 minutes was 37.01$^{\circ}C$, for S minutes 37.09$^{\circ}C$ and for minutes 37.21$^{\circ}C$. As a result of this study, these differences among time intervals were statistically significant, but there were not so much differences as to be considered important in the clinical practice. Therefore, there would be clinically little difference between two groups who are taking for 3 minutes and for 10 minutes.

  • Background : The most frequently reported risk factors for head and neck suamous cell carcinoma are smoking and alcohol. But in a recent overview, human papilloma virus(HPV) infection was revealed the important carcinogenic factor in oropharyngeal cancer. We aimed to clarify whether HPV directly effects on the oncogenesis and biologic behavior of hean and neck squamous cell carcinoma by comparison with infection prevalence, and physical status of virus. Material and Method : We used HPV genotyping DNA chip(Biocore, Korea, Seoul) arrayed by multiple oligonucleotide probes of L1 sequence of 26 types of HPV and HPV genotypes are identified by fluorescence scanner. The copy numbers of HPV E2 and E6 open reading frames(ORF) were assessed using a TaqMan-based 5'-exonuclease quantitative real-time PCR assay. The ratio of E2 to E6 copy numbers was calculated to determine the physical status of HPV-16 viral gene. Results : We observed a significant difference in HPV prevalence between tonsillar cancer group and control group(73.1% vs. 11.6%), and most of the HPVs were type 16(87.2%) and integrated(94.1%) state. In terms of oral tongue cancer, we demonstrate that 30.5% has integrated HPV-16 in cancer tissue. But Glottic cancer only 1% is related to HPV-16 integration. Conclusion : This study revealed significant relationship of HPV prevalence with oropharyngeal and oral tongue squamous cell carcinoma. Most of HPV were 16 type and integrated or mixed, HPV-16 integration could be directly related to the carcinogenesis.

  • Objectives : To estimate the prevalence of hypertension, rates of awareness, treatment modalities, and control of hypertension, and also to identify factors in rural Korea that are related to these aspects of hypertension. Methods : A cross-sectional survey, including blood pressure(BP) measurements and interviews, investigating the variables in the health belief model was peformed from August to November, 1999 on 1,426 (79.4%) study subjects out of 1,797 registered residents over 30 years old in Ibansong-Myun, Chinju City. A second survey was peformed from January to March, 2000 on 376 (80.0%) subjects out of 470 hypertensive (or suspected hypertensive) subjects found in the first survey. Two BP readings were taken in each survey using a standard mercury sphygmomanometer. Hypertension was defined as either a BP reading $\geq$ 140/90 mmHg in both surveys, or as subjects on oral hypertensive medication. Results : Estimated hypertension prevalence was 24.9% for men, and 30.4% for women. Rates of hypertension awareness, treatment (the regular use of oral hypertensives), and control (reduction of BP to <140/90 mmHg) were 52.5%, 34.4%, and 12.9%, respectively. The factors related to lower hypertension awareness in the logistic regression analysis were male gender, farming occupation, and higher perceived barrier to medical treatment (those for whom visiting health professionals is a burden). Conclusions : To improve the low awareness, treatment, and control of hypertension, a more active and out-reaching hypertension control program, including routine BP measurements for every visitor to primary care facilities, is needed in rural Korea.
