The aims of this study were to establish the effect of gender and age on number of fungiform papillae and electrogustometric thresholds of the tongue, and to determine the relation between number of fungiform papillae and electrogustometric threshold. Sixty-two healthy subjects of 20 to 39 years old were enrolled in this study. Examination areas were defined as center, anterior, left lateral, right lateral, and posterior on the dorsal surface of the tongue, which was stained with methylene blue dye and photographed with a scale bar on it. The number of fungiform papillae within $1\; cm^2$ square area of each examination site was counted twice. The counted values were averaged to produce means. Taste thresholds were measured three times on each examination area using an electrogustometer. Means of the threshold values were calculated. 1. The number of fungiform papillae was the largest at the anterior examination area, followed by right lateral, left lateral, posterior and central. Women had more fungiform papillae than men at anterior, right lateral, and center areas. Subjects in twenties showed more fungiform papillae than those in thirties at anterior, right lateral, and left lateral areas. 2. Anterior area of the tongue measured the lowest electrogustometric threshold, followed by left lateral, right lateral, posterior and center. The threshold was higher in men at anterior and right lateral areas. The subjects in thirties had higher threshold only at right lateral area than those in twenties. 3. Electrogustometric threshold was inversely correlated with the number of fungiform papillae at anterior and posterior areas. The results showed that the number of fungiform papillae and taste threshold varied according to tongue locus, and they were influenced by age and gender. The results also suggested that the number of fungiform papillae was related to electrogustometric threshold inversely.
The purpose of this study is to provide information that will help understand unique characteristics of mathematically gifted students and that can be utilized for special programs for mathematically gifted students, by investigating difference and relationship between attribution styles and attitude toward mathematics of mathematically gifted students and those of regular students. For that purpose, 202 mathematically gifted students and 415 regular students in 5th and 6th grades at elementary schools were surveyed in terms of attribution styles and attitude toward mathematics, and the result of the study is as follows. First, as for attribution styles, there was no difference between gifted students and regular students in terms of grade and gender, but there was significant difference in sub factors because of giftedness. Second, there was not significant difference between grades. but there was significant difference in sub factors between genders. Mathematically gifted students were more positive than regular students in every sub factor excepting gender role conformity, and especially they showed higher confidence and motivation. Third, according to the result of correlation analysis, there was significant static correlation between inner tendencies and attitude toward mathematics with both groups. The gifted group showed higher correlation between attribution of effort and attitude toward mathematics and inner tendencies and confidence than the regular group. The gifted group showed higher correlation in sub factors, and especially there was high static correlation between attribution of talent and confidence, and attribution of effort and motivation. Fourth, according to the result of multiple regression analysis, inner tendencies showed significant relation to attitude toward mathematics with both groups, and especially the influence of attribution of effort was high. Both attribution of effort and attribution of talent were higher in the gifted group than the regular group, and attribution of effort had a major influence on practicality and attribution of talent had a major influence on confidence.

Purpose: The aim of this retrospective study was to provide long-term data about the correlation between multifactorial local factors and the survival of implants. Material and methods: During 19 years (1991 to 2009), 2796 implants were placed in 879 patients. From dental charts and radiographs, the following data were collected: patient's age at implant placement, gender, implant system, surface, length, diameter, location of implant placement, bone quality, primary stability, type of prosthesis. The correlations between these data and implant survival were analyzed. Statistical analysis was performed using Kaplan-Meier survival analysis, Chi-square test, odds ratio. Results: 1. Among the 2796 implants, 150 implants failed that resulted in a cumulative survival rate of 94.64%. The cumulative survival rate of smooth surface implants (91.76%) was lower than rough surface implants (96.02%). 2. Anatomic location, implant surface, diameter of smooth surface implant, primary stability, type of prosthesis, patient's age and gender were significantly associated with implant survival (P < .05). 3. No significant difference in implant survival was found in relation to the following factors: implant length, bone quality, diameter of rough surface implants and type of rough surface according to implant manufacturer (P < .05). Conclusions: Local factors such as anatomic location, implant surface, diameter of smooth surface implant, primary stability and type of prosthesis have a significant effect on implant survival.
Objectives : This cross-sectional study was performed to examine if the serum gamma-glutamyltransferase (GGT) level that is within its normal range is associated with the risk of type 2 diabetes and if the association between the waist hip ratio (WHR) and type 2 diabetes is different depending on the serum GGT levels. Methods : The study subjects were 23,436 persons aged 40 years or older and who participated in regular health check-ups at 11 hospitals (males: 5,821, females: 17,615). The gender-specific quintiles of the serum GGT and WHR were used to examine the associations with type 2 diabetes. Results : The serum GGT levels within their normal range were positively associated with type 2 diabetes only in women. The adjusted odds ratios (ORs) were 1.0, 1.0, 1.4, 2.1, and 2.5 according to the quintiles of the serum GGT ($p_{trend}$<0.01). The WHR was more strongly associated with the prevalence of diabetes among the women with a high-normal serum GGT level as compared with those with a low-normal serum GGT level (p for interaction=0.02). For example, the adjusted ORs for women with a low normal serum GGT level were 1.0, 1.2, 1.5, 2.2, and 2.4 according to the quintiles of the WHR, while those figures were 1.0, 2.4, 3.6, 5.0, and 8.3 among the women with a high normal serum GGT level. However, in men, the serum GGT was very weakly associated with type 2 diabetes and the association between the WHR and type 2 diabetes was not different depending on the serum GGT level. Conclusions : Serum GGT within its normal range was positively associated with type 2 diabetes, and central obesity was more strongly associated with the prevalence of type 2 diabetes when the serum GGT level was highnormal. However, these associations were observed only in women, which is different from the previous findings. The stronger relation between central obesity and type 2 diabetes among women with a high-normal serum GGT level can be useful for selecting a group that is at high risk for type 2 diabetes irregardless of whatever the underlying mechanism is.
This study was executed to find the effects of dietary control and oral health care on dental caries and oral problems in elementary school students, including the effects of nutritional and oral health education on the prevention of dental caries. 1. The oral health study found that 88.9% of students brushed their teeth everyday, 63.7% 2 times a day, and 50.4% in the morning and at night. 2. According to the general characteristics whether or not, the female students had more dental caries than the males, and 29.1% of the students that had dental caries ate snacke 1 or 2 times a day. 3. After the nutritional education, more students brushed their teeth in the after meal 4. According to gender, grade and nutritional education for oral health care, male students and higher grade students were more aware that “brushing teeth after meals is better than before”. The male and higher grade students, after the nutritional education, were more aware that “Bones and teeth are made from calcium”, and “Fluorine prevents teeth from dental caries” and the differences between the genders were statistically significant in relation to both these facts (p〈0.05) and before and after education (p〈0.01). The male and higher grade students, and those nutritionally educated were more conscious that “vegetables and fruits are good for teeth”, with the differences before and after the nutritional education were statistically significant (p〈0.05). The male and higher grade students were well aware that “Foods that have sugar cause dental caries”, and significant differences were shown between grades (p〈0.05). The male and higher grade students, after the nutritional education and were well aware that “Milk is good for teeth”, with a significant gender difference (p〈0.05). The female and higher grade students, and those after nutritional education were well aware that “Dental caries can not be perfectly cured once it had already occurred”. after nutrition, but not much differences.

Recently, the importance of the fathers role in the care of young children has been emphasized in Korea for the balance of childcare responsibilities between mothers and fathers. This study investigates the trends in paternal childcare in Korea over the last 15 years. Childcare is divided into primary and developmental care and fathers's Childcare time and participation rates are inverstigated for dual- and single-income households. Data are collected from the four waves of the five-yearly Statistics of Korea Life Time Surveys between 2004(t1) and 2019(t4) including the workday time diaries of fathers with preschool children(n1=2,264, n2=1,242, n3=959, n4=952). Three major results are identified. First, paternal childcare time and participation rates have increased with dual-income fathers spending 24 more minutes a day with their young child(ren) in 2019 than in 2004, which is nearly double. Second, in the analysis of fathers' childcare time use and participation rates comparing primary and developmental care, primary care is found to have increased more than developmental care, especially among dual income fathers: this further exhibits a reversed relation between primary and developmental care over time. Third, the determinants of paternal childcare time are fathers' age, market labor time, commuting time, gender equality consciousness, and education. In particular, market labor time was significant in all four waves, while gender equality consciousness is only significant for single-income fathers. Based on these results, a specific agenda is provided for family-friendly policies to improve the balance of childcare roles between fathers and mothers, especially encouraging increased(significant and sufficient) participation of fathers in primary care activities.

The purpose of this study is to analyze the impact of self-efficacy of SMEs' organization members on job engagement and job performance, and to analyze the difference between gender and marital status by applying SEM-ANN analysis. To accomplish the study purpose, 285 valid samples were collected from 400 SMEs' organization members and analyzed. In this study, self - efficacy consisted of three sub-dimensions: self-confidence, self-regulation efficacy, and task difficulty preference. As a result of the analysis, self - efficacy such as self-confidence, self-regulation efficacy, and task difficulty preference had a positive direct effect on job engagement. In addition, self-efficacy and self-control efficacy have a positive effect on job performance, but the preference of task difficulty has no significant effect. In addition, job engagement has a positive(+) effect on job performance, and has a mediating role in the relationship between self-efficacy and job performance. Also, married males preferred self-regulation efficacy, while females preferred self-regulation and self-control efficacy regardless of marital status. The purpose of this study is to present the framework of self-efficacy-job engagement-job performance of SMEs by measuring the self-efficacy related researches mainly in education and service industries, and is meaningful that companies can help to find the basis of management of organization members by gender and marital status of organization members. In addition, the SEM-ANN analysis process of this study is different in that it explains the nonlinear (nonobservative) relationship that can analyze the influence or the combination of the reference variables in the linear (compensatory) relation using the SEM.
Purpose: This thesis focuses on researching the burden of the Home Health Care that the Family Care-givers have. Method: This study had been conducted for the duration of 3 consecutive months from January 2006 to March 2006 and had investigated 120 person registered as the Home Health Care Clients to a University Hospital located in Incheon City. The thesis adopted the 'feeling of burden' measuring method jointly developed by Seo, Mi-Hye and Oh, Ga-Sil(1993), and FACES-III(Family Adaptability Cohesion Evaluation) developed by Olson(1985) etc. translated by Kim, Yun-Hee(1989) as the measuring method for Family Function. Result: The overall Health Status of the Home Health Care Clients was 2.18 point of average out of 3 point, where as 1.83 for Activities of Daily living and 1.98 for Vital sign, which are below the average. In the mean time, the Competence for Modified Barthel Index marked 30.88 point out of the full mark. The analyzed result of the burden that the family members have was 3.43 point of average out of 5 point which shows that the interviewee feel that they are considerable burden to their families. When it comes to 'the Burden to the family members' and 'the Function of the family' according to the characteristics of the patient, the result shows statistically significant differences, which are varied according to gender, the relationship between the care-givers and the patients. When it comes to the Family Cohesion, the difference was examined as 'statistically significant' according to the Academic background of the patients and the relationship between the patients and the interviewee.(p<0.05). The result also suggests that there exists 'Negative correlation' among the level of patients' health status, the Family Cohesion and the Family Burden. Conclusion: From the result of this study stated above, this thesis is strongly insisting that there is an urgent need for us to develop a health care mediation program, which could eventually reduce the burden of home health care that the patients' family have. At the same time, a follow-up research to prove the effect of the program is imminent.

Objective : To analyze the radiosurgical results of intracranial meningiomas after Gamma Knife radiosurgery (GKS) and to assess the possible factors related to the outcome and complications in treating meningiomas. Patients and Methods : We retrospectively reviewed the clinical and radiological data in 179 patients(194 lesions) treated with GKS for intracranial meningiomas between May 1992 and October 2000. Radiosurgical responses were categorized as shrinkage, stasis and enlargement, and we defined the shrunken and static group as a radio-logical control. A Cox proportional hazards model was used to evaluate the correlation between the radiosurgical outcomes and various factors such as location and size of tumor, age and gender of patients, relation to venous sinus, pre-GKS degree of edema, treatment modality, radiosurgical parameters, and pathologic findings. Results : Patients were grouped into skull base meningiomas(57.7%), non-skull base tumor including convexity, parasagittal, and falx meningiomas(37.1%), and others(5.2%) according to the location of tumors. The mean maximum dose and the margin dose of tumor was 30.0Gy(19-45Gy) and 15.1Gy(9.5-24.5Gy), respectively. The mean volume of the tumors was 9.4cc(0.003-45.0cc). The radiologic control rate was 97.1%. The radiation induced imaging change with or without neurologic deficit was the most common complication(23.6%). There were seen mostly in convexity, parasagittal, and falx meningiomas which were deeply embedded in cortex. Conclusion : GKS for intracranial meningioma seems to be safe and effective treatments. However, GKS should be considered very cautiously in non-skull base tumor such as convexity, parasagittal, or falx meningiomas with regards to patient's age and general condition, size and location of tumor, pattern of embedding into cortex, presenting symptoms and patient's preference.
The aim of this paper is to suggest a design guideline for a teaching assistant robot by finding out images that satisfy the role of the teaching assistant robot, and to search for a body features that show such images. Role images of teaching assistant robots were established from literature review and factor analysis. And eight elements of body features were extracted from human's elements of body feature. Robot external form samples varied according to the body feature was modeled three-dimensionally. Children, who are the main users of teaching assistant robots, valuated the 3D robot samples projected onto wall in real size. The valuation basis was role images of teaching assistant robots, adjectives about age and gender, preference, and appropriateness as teaching assistant robots. The result of valuation was analyzed by analysis of variance, and analysis of correlation. The result revealed the fact that four elements of body feature (the ratio of head length, height, the ratio of breast girth, and waist girth) were related to role images. Among these elements, height and waist girth was more important than the rest, particularly, waist girth had strong relation with all the role images. Also, in order to reveal tender and kind image, the ratio of head length was proved to have to be adjusted according to waist girth. On the basis of these result, a design guideline for a teaching assistant robot was suggested.
