This study aimed to analyze the ten years cancer incidence based on diagnosis years 2000-2009, and to evaluate the quality of cancer registry in Daejeon City and Chungcheongnam-Do, Korea. Crude incidence rate and age-standardized incidence rate (ASR) in these two regions were compared, and validity of incidence data was assessed by three indicators; age unknown (Age UNK%), histological verification (HV%), and death certificate only (DCO%). Mortality/incidence ratio (M/I ratio) was used to evaluate completeness of incidence data. Incidence rate differences were assessed using Poission distribution and calculated their 95% confidence interval of ASR, and those by sex, age, and region were compared by incidence rate curve. As a result, the highest cancer site during 2000-2009 was stomach in both regions, and incidence prpportion were 18.8% in Daejeon, 21.5% in Chungnam. The overall cancer incidence was higher in males than in females, and ASR of total cancer in Daejeon increased 0.6% (from 322.1 to 323.9 per 100,000) for men and 60.3% (from 203.9 to 326.8) for women, that in Chungnam increased 14.3% (from 294.7 to 336.9) for men and 70.7% (from 156.5 to 267.1) for women. The Age UNK% during 2000-2009 were 0.0% in both regions. MV% for men was increased from 71.8% to 88.5% and that for women was increased from 78.1% to 93.2%. DCO% for men was decreased from 6.4% to 0.7% and that for women was decreased from 5.4% to 0.8%. M/I ratio was ranged from 15.3% to 62.1% and can be evaluated fairy good registration.

This study was conducted to develop a set of EST-SSR marker for the purity test of commercial F1 hybrid cultivars in the watermelon. A total of 353 EST-SSR were selected and tested on seven F1 cultivars and their 11 parental lines achieved from NH Seeds Inc., Korea. Among tested 96 primer sets, WMU0056 for 'Orange', WMU0400 for 'Heukbo', WMU0056 and WMU0400 for 'Sindong', and WMU0056 and WMU0400 for 'Serona' revealed polymorphisms between the parental lines and heterozygosity from these F1 cultivers. Of 122 primer sets tested for 'Haedong', WMU0056, WMU0400, WMU0580, WMU1211, WMU4136, and WMU448 showed polymorphisms that were appropriate for the F1 purity test. WMU0056 and WMU0400 can be useful for 'Haedong', as well. Relatively low polymorphisms between parental lines were detected for 'Kulnara'(5%) and 'Hwangpea'(2%), and therefore, all 353 primer sets were tested on these cultivars. As the result, WMU5339 and WMU7003 were found to be useful for the F1 purity test in 'Kulnara' and 'Hwangpea', respectively. Using these EST-SSR markers developed by ICuGI, hybridity of the seeds for four F1 cultivars produced from farmers was evaluated, and levels of the F1 purity higher than 97.5% was observed from all seed populations. Our results indicated that the watermelon EST-SSR marker information posted in ICuGI could be utilized for developing codomiant and locus-specific markers that are highly effective for the F1 purity test.

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.

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.
