This study explored the effect of fathers' childrearing participation and their recognition about child care situation on fathers' satisfaction with nonparental child care. The results of this study are as follows: First fathers who had finished college education whose family had more family income and whose wives had jobs were more participated in childrearing practice than fathers who had finished high school whose family had less family income and whose wives had no job, Second when childre's age were over 5 years fathers tended to recognize about child care situation. That is fathers whose children were over 5 years old more recognized about how caregivers took care for children's congnitive development and were more satisfied with educational materials of child care centers than fathers whose children were less 5 years old. Third fathers' recognition about child care situation were found to mediate the relationship between fathers' childrearing participation and fathers' satisfaction with nonparental child care.

Objectives: Using a PHR(Personal Health Record) is very important for the management of chronic disease and health. The young age group in this study was asked to pretend that they were members in the old age group (adult group here after) in order to investigate the recognition level differences in such conditions. Methods: We conducted face to face surveys with two age groups. 131 Adults and 398 University students, from May 11 to 22 in 2009. The questionnaires were composed of 18 items. Results & Conclusion: Adults replied more favorably than University students in using PHR willingness(University group 3.3score, Adults 3.7score) and recommendation(university 3.1score, Adults 3.8score). Adults liked paper PHR (63.2%), whereas, University students favored electronic Personal Health Record (71.1%). University students were highly concerned about disclosing the information(4.5score) of their PHR. They thought the appropriate time of education for PHR is high school or University degree. Therefore, in the future, it is vital that a PHR for young age group should be begun in early education and that an ePHR should be developed.

The purpose of this study was to investigate the relationship between age, physical activity (walking, strength exercise), subjective body shape recognition, and weight change with subjective health status in the population aged 30 years or older among the data of the National Health and Nutrition Examination Survey (2018) of Koreans. The subject and method of this study was a secondary analysis study using the 7th 3rd year National Health and Nutrition Examination Survey (2018). Age, walking days per week, strength training days per week, subjective health status, subjective body shape recognition, and weight change during the year were used the SPSS (p<.01). The response rate of walking for 7 days (every day) was 21.9% for those aged 30-45, 27.2% for those aged 50-64, and 26.6% for those aged 65 or older. aged 8.4% and over 65 years old 7.9% (p<.001). The subjective health status was positively correlated with age (.091), number of walking days per week (.739), number of days of strength exercise per week (.530), subjective perception of body shape (.256), and weight change over one year (.303). There was a relationship (p<.01). In this study, the age group that answered 'bad' in subjective health status was the highest at 21.4% of those aged 65 or older, followed by 15.7% of those aged 50-64 and 11.0% of those aged 30-45. This could be expected to improve subjective health status by walking and strength training. Based on these results, it was intended to provide basic data for preparing health-related programs to improve subjective health status of individuals according to age.

The cognition of Korean kinship names was examined in children in the 1st, 3rd, 5th, and 9th grades (N=188) of public school. The task consisted of 43 items which identified the relative relationships of cognates and cognates-in-law. It was found that the main effects of age and residential area on cognition scores were significant and the interaction effects between the variables were also significant. As expected, older children performed the task more precisely than the younger children and children in Seoul performed better than in outlying regions. Under 15 years of age, the scores in Seoul were higher than in Andong, but at the age of l5, this trend was reversed. The gap between residential areas under 15 years of age could be explained by differences in cognitive ability and test effects, but the gap at 15 by culture.

Formant is one of the essential vocal features for research of voice production, recognition and synthesis. Numerous studies were established on foreign languages including English vowels. However, studies related to Korean were done with a limited number of voice data. In this study, we compare four formants according to age and gender using a large number of Korean monophthongs. A total of 2614 Korean speakers participated in our experiments. We summarize statistical results by mean and standard deviation for each formant of five monophthongs. The results show a notable difference in each age and gender group. A quantitative study based on a large dataset is suggested for future studies on Korean speech sounds.

The rapid proliferation of wireless networks and mobile computing applications has changed the landscape of network security. Anomaly detection is a pattern recognition task whose goal is to report the occurrence of abnormal or unknown behavior in a given system being monitored. This paper presents an efficient rough set based anomaly detection method that can effectively identify a group of especially harmful internal attackers - masqueraders in cellular mobile networks. Our scheme uses the trace data of wireless application layer by a user as feature value. Based on this, the used pattern of a mobile's user can be captured by rough sets, and the abnormal behavior of the mobile can be also detected effectively by applying a roughness membership function with the age of the user profile. The performance of the proposed scheme is evaluated by using a simulation. Simulation results demonstrate that the anomalies are well detected by the proposed scheme that considers the age of user profiles.
