This study aimed to secure basic data for the development and operation of well-aging education programs by analyzing the physical, mental, and socio-economic needs of well-aging education for successful aging. The research tool was developed as a questionnaire to investigate the perception of well aging and the needs of well-aging education in terms of physical, mental, and socio-economic aspects. In February 2021, 1949 adults over the age of 19 were surveyed through an online and mobile survey by Gallup Korea. Descriptive statistics analysis, variance analysis, Borich needs analysis, and IPA analysis were conducted to analyze the needs of well-aging education. The results revealed economic power, exercise, and chronic disease management to be high in terms of the overall priority of the education needs for well-aging, and infectious disease management, independence, and social responsibility were surveyed in the order of low education needs. In terms of economic power, education needs were highest among all age groups except for the middle-age group (35-49 years old), 82.4% of all respondents, and education needs for exercise and chronic disease management were highest in the middle-age group. Therefore, it is necessary to develop well-aging education programs for each life cycle. These results are expected to be used as empirical data in establishing a platform for developing and operating educational programs for well aging.

This study was performed to analyze the microbial contamination levels of three non-heated rice cake manufacturers in terms of seasonal manufacturing process and to investigate the effects of summertime soaking on contamination levels and temperature-controlled soaking in water on reduction in microbial levels. The total aerobic bacteria (TAB) ranged from 2.69 log CFU/g to 5.08 log CFU/g in the produce, but the microbial contamination increased sharply during soaking. The levels of TAB and coliforms during summer soaking were 7.01 and 3.96 log CFU/g, respectively, and this was significantly higher than those in other seasons. The contamination level was high in the subsequent freezing, with the TAB level (6.24 log CFU/g) exceeding the legal standard. The temperature of soaking water in summer increased from 19.1℃ to 26.8℃ after 12 h of soaking. The microbial contamination was significantly high commensurate with increased soaking time, and the TAB level in the frozen process exceeded the legal standard from 9 h of soaking. The use of ice packs to prevent the increase in temperature of the soaking water in summer resulted in maintenance of temperature at 20.1℃ for up to 12 h. The average TAB value in the freezing process was 4.42 log CFU/g after 12 h of soaking, and this is 1.77 log CFU/g lower than that before. Based on these results, it was determined that controlling the soaking time and water temperature are essential for the production of a safe unheated frozen rice cake. The safety of the HACCP system could be established by applying these preventive management standards.

This study examined the effects of the shear bond strength when the surface condition of the metal and zirconia, each being the lower structures, was different when determining the bond strength (metal group) of the metal lower structure with upper ceramics, and the shear bond strength (zirconia group) of zirconia lower structure with the upper ceramics in prosthetic appliances of metal-ceramic crown and zirconia-ceramic crowns. The metal groups were divided into a total of four groups: the group with no condition on the metal surface(NM), the group with sand-blasting(SM), the group with applied opaque ceramics(OM), and the group with applied opaque ceramics and sand-blasting(SOM). The zirconia groups were also separated into four groups: the group with no condition(NZ), the group with sand-blasting(SZ), the group treated with ZirLiner on the zirconia surface(LZ), and the group applied with ZirLiner along and sand-blasting(SLZ). To examine the effects on the shear bond strength according to the surface condition of each of the four metal and zirconia groups, SPSS was used to conduct one-way ANOVA. For metal-ceramic crowns, it would be best to apply opaque ceramics after sand-blasting on the surface of the metal, the lower structure. For zirconia-ceramic crowns, it is recommended to apply the ZirLiner after sand-blasting on the surface of zirconia, the lower structure.

This study was designed to investigate the status of orthodontic treatment and facial plastic surgery among 389 patients who visited dental clinics located in Seoul and Gyeonggi Province. After the collection of data, an analysis was carried out using a spss statistical program. The analysis results are as follows. the level of satisfaction with orthodontic treatment from patients with experience of the orthodontic treatment turned out to be high(p<0.01). Women considered 3.01 to 4 million won to be reasonable cost for orthodontic treatment (p<0.05), which is higher cost recognized by men, and patients with experience of orthodontic treatment recognized 19 to 24 months as the proper orthodontic treatment period(p<0.01). In addition, women showed higher figures than men in their awareness on the need for orthodontic treatment checkups(p<0.001), and facial plastic surgery experience (p<0.01). With respect to the part of the face on which they hoped to have plastic surgery, eye plastic surgery was higher in women (p<0.01), and nose surgery turned out to be higher in patients with experience of orthodontic treatment(p<0.05). Meanwhile, women considered the eye as the most important part among other facial areas (p<0.001), and they recognized that dentist should perform plastic surgery on both jaws among facial areas(p<0.01). In conclusion, the dental medical staff should provide consultations and operate treatment systems in consideration of gender differences and needs of dental patients. In the case of orthodontic treatment for the improvement of facial appearance, especially double jaw surgery which is closely related to the oral function, professional dental medical staff needs to perform the operation, considering the special oral environment. In addition, it is determined that provision of relevant medical information and promotion of dental service is required to provide patients with correct knowledge about orthodontic treatment and facial plastic surgery.

The purpose of this study is to figure out and establish the basic data that can help improve management of oral healthcare for the international marriage migrantwomen. In this sense, we surveyed questions on 237 women out of 1,300 immigrant women, who have participated the program in operation by multi-cultural household supporting center, in a fashion of face-to-face investigation and on-the-spot direct cavity inspection simultaneously from May 1th to October 31th, 2010. Collected data were electro-statistically computerized under SPSS 17.0 program and analyzed with frequency analysis, recurrence analysis and logistic regression analysis respectively. Foundings were revealed as follows; On the nationality base, show the data in the ratio of 38.8% for Vietnamese, 29.1% for Philippine, 12.2% for Chinese and 6.8% for Japanese respectively. Current oral cavity status shows in the ratio of 60% with carious tooth symptoms, 40% without carious tooth symptom. Philippine women have irregular sets of tooth in many a case. (i.e., in short of numbers of teeth, due to removing individual tooth.) Japanese ladies are indicated to have less irregular sets of tooth, in comparison with that of the other immigrants from overseas. And lastly, high-income immigrant women in general were found having less numbers of unhealthy sets of tooth. Getting older, it appears that decayed tooth symptom is on the tendency of getting less in the field of dentistry circles. Immigrant ladies living with husbands under higher education background usually are found living a life in the less ratio of having toothache. A full-time immigrant housewives, however, are living everyday life in more times of suffering with tooth disease.

The purpose of this study is to analyze the factor giving effect to department selection, learning adaptation and attributional-style after entering school by selecting university students as targets and help high school students who will graduate soon and university students select department and direction. Those were analyzed by using 287 questionnaire data from June 1 to June 30, 2011. The study result revealed that 64.5% of students considered 'popularity and employment prospect' first when they select department. Generally, it was researched that when selecting department, 68.8% of women and 78.7% of health major considered 'popularity and employment prospect'(P<0.05, P<0.01). For learning adaptation and attribution trend of each major, health major showed that learning adaptation was high when motif was high and application score was high and for the relationship with attributional-style, health major showed higher internal attributional-style, showing significant difference(P<0.05). When synthesizing the results above, it is necessary to develop and use the program that can develop internal attribution trend of students on the basis of attributional-style. For planned and careful selection, it is necessary to perform synthetic consulting through direction search program that considers entrance period of middle school or high school, general affairs of university or direction guide to increase department or direction adaptation in the future.

This study was designed to assess the factor of influence to occupational stress who work in the field of firefighters and questionnaire was uesd to analyse the stress scores and find the primary factors influence to occupational stress. The number of respondents were 408 who received the refresher training and period of investigation was august 2011 through october 2011. A structured questionnaire was employed to evaluate the participants' socio-demographics, job-related factors, health-related behaviors, occupational stress, reaction factor (fatigue, job satisfaction) and buffer factor (social support). Occupational stress and fatigue were assessed using the Korean Occupational Stress Scale-Short Form (KOSS-SF) and the Multidimensional Fatigue Scale (MFS), respectively. The analysis showed that we found a strong correlation between fatigue, job satisfaction and occupational stress. Occupational stress was associated with an increased risk of fatigue and decreased the job satisfaction. In the multiple regression analysis(stepwise), main factor that influence to occupational stress were job satisfaction, gender, age, processing number for a day, exercise. In logistic regression analyses, a higher occupational stress was associated with higher odds of fatigue(High) and the odds was down by 15.0% after adjustment for job satisfaction, gender, age, processing number for a day, exercise. Thus, a job satisfaction promote program for the reduction of occupational stress and the promotion of firefighters's health is strongly recommended.

The present study was conducted to identify the factors related to the hypertension, and to offer the evidence of 1st prevention of hypertension. 2,230 male workers aged 30-59 years were observed the relationships between hypertension and age, BMI, glucose intolerance, smoking, alcohol drinking, regular exercise, eating habits using data from health check-ups in 2011. As a results, the incidence rate of hypertension was 18.8% of 30-39 year old group, 23.8% of 40-49 year old group, 33.0% of 40-49 year old group. The incidence rate of hypertension was significantly higher as age and BMI ascend, and it was higher in the group of abnormal glucose intolerance, regular alcohol intake, no regular exercise than their respective counterparts. The multivariable-adjusted odds ratio of hypertension increased significantly as there is an increase in age, and the group of abnormal glucose intolerance, smoking, regular alcohol intake, no regular exercise. In conclusion, obesity, glucose intolerance, alcohol intake, and physical inactivity are risk factors for hypertension, therefore we need the control of these factors for 1st prevention of hypertension.

The purpose of this study was to investigate how employed dental hygienists (graduates) and alumni are aware of dental health insurance and how to organize their classes for running efficient dental health insurance courses, and therefore to suggest opinions on the introduction of professional dental hygienist qualifications. The analyses was carried out using IBM SPSS Statistics 24.0. Sixty-nine students (56.1%) preferred one semester dental health insurance course as two semester courses and 63 students (51.2%) preferred theoretical course as practical course. Ninety-six (78%) students preferred dental health insurance claimants as others for their most necessary certification. Ninety-three dentists (75.6%) thought of the dental hygienist as the appropriate occupation for dental health insurance claims. The correlation coefficient was significant at the 0.01 level (both sides) and all showed a positive correlation. The effect of subjective understanding of dental health insurance and the perception of dental health insurance claim on students' intention to complete those courses explained 32% of the response, and the effect of the intention to complete those courses on the willingness to earn a certificate explained 22.3%. This study reveals the willingness of students to complete those courses to acquire qualifications in order to achieve a competitive advantage in employment, and suggests the necessity of institutional improvements such as changing the method of dental insurance education, varying the class time distribution, and introducing dental health insurance professional dental hygienist qualification in the country.
