The purpose of this study is to identify the levels of informationized life of individual, consumers knowledge and attitudes to informationized society, and the recognition of consumer problems in informationized society, and to investigate the related variables. Data were collected from 693.consumers living in Seoul using the constructed questionnaires by the authors. Frequency, Percentage and Multiple Regression Analysis were applied for the analysis. The level of informationized life of consumers was lower than the mid-point of the scale, the level of the consumers knowledge about informationized society was sightly higher than mid-point of the scale, and the consumer attitudes to informationized society appeared to be positive. The level of the recognition of consumer problems in informationized society was higher than the mid-point of the scale,and was influenced by job, age of consumers, and the level of consumers knowledge about informationized society.

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.

The purpose of this study was to examine the degree of recognition and reading experience of the rental housing law in rental housing residents. The subjects of this study were 359 residents who lived in Gwang-Ju and who were surveyed by questionnaire in 2000. Data was analyzed with the statistical methods of frequency, percentage, mean and chi-square. The main results of this study were as follows: 1) About 64% of the residents knew the rental housing law 2) Degree of recognition about the rental housing law was significant on age, apartment size, housing rental deposit, and monthly rental fee. 3) About 92% of the residents didn't read the rental housing law. 4) Degree of reading about the rental housing law was not significant on the level of housing characteristics. If the residents knew about rental housing law, it might be prevented the damage from housing rental deposit refund debate, contract termination and rental housing company dishonor.

목적 : 성인병관리 및 개인건강관리를 위해 개인건강기록(PHR)은 매우 중요하다. 현재 노인 또는 장년층과 미래 노인, 장년층과의 차이를 비교해 보기 위해 젊은층(대학생)과 성인을 대상으로 조사하였다. 방법: 두 연령집단의 면대면 설문조사를 성인(131명)과 대학생(398명)을 2009년 5월 11일부터 22일까지 실시하였다. 설문지는 18개 문항으로 구성되었다. 결과 및 결론: 젊은층보다는 성인층에서 PHR을 사용하겠다는 의지(대학생그룹3.3, 성인그룹3.7)와 지인들에게 PHR을 추천하겠다는 의지(대학생그룹3.1, 성인그룹3.8)가 비교적 높게 나타났다. 반면, 성인그룹은 종이형 PHR(63.2%)을 선호하였으며 대학생그룹은 ePHR(71.1%)을 더 선호하였고, PHR에 담겨져 있는 정보유출에 대한 우려가 성인그룹(3.7)보다 대학생그룹(4.5)이 높은 것으로 나타났다. PHR에 대한 교육 시기는 고등학교와 대학교로 응답하였다. 따라서 젊은층의 PHR활성화를 위해서는 ePHR에 대한 조기교육과 사용이 편리한 PHR개발이 이루어져야 할 것으로 사료된다.

본 연구의 목적은 한국인 대상의 국민건강영양조사(2018년) 자료 중 30세 이상의 인구를 대상으로 나이, 신체활동 (걷기, 근력운동), 주관적 체형 인식, 체중의 변화가 주관적 건강 상태와의 관계를 알아보고자 하였다. 본 연구의 대상과 연구방법은 제7기 3차년도 국민건강영양조사 (2018년)를 이용한 이차분석연구이다. 나이, 1주일간 걷기 일수, 1주일간 근력운동 일수, 주관적 건강 상태, 주관적 체형 인식, 그리고 1년 동안 체중 변화 유무를 변수로 이용하여 주관적 건강 상태와의 상관성 분석을 SPSS를 활용하여 통계적 유의성 있는 결과를 활용하였다(p<.01). 7일(매일) 걷기를 한다는 응답율은 30-45세는 21.9%, 50-64세는 27.2% 그리고 65세 이상은 26.6%이며, 5일 근력운동을 한다는 응답율은 30-45세는 3.6%, 50-64세는 8.4% 그리고 65세 이상은 7.9%이다(p<.001). 주관적 건강 상태는 나이 (.091), 1주일간 걷기일수(.739), 1주일간 근력운동 일수 (.530), 주관적 체형인지(.256), 1년간 체중 변화(.303)에 대해서는 양의 상관관계가 있었다(p<.01). 본 연구에서는 주관적 건강 상태는 '나쁨'이라고 응답한 연령대는 65세 이상이 21.4%로 가장 높았으며, 그 다음으로는 50-64세는 15.7%, 30-45세는 11.0% 순으로 나타났다. 이는 걷기, 근력운동을 함으로써 주관적 건강 상태가 좋아질 것으로 기대할 수 있었다. 이러한 결과를 토대로 연령에 따른 개인의 주관적 건강 상태 향상을 위한 건강 관련 프로그램을 마련하는데 기초자료로 제공하고자 한다.

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.

Human age estimation is one of the key factors in the field of Human-Robot Interaction/Human-Computer Interaction (HRI/HCI). Owing to the development of deep-learning technologies, age recognition has recently been attempted. In general, however, deep learning techniques require a large-scale database, and for age learning with variations, a conventional database is insufficient. For this reason, we propose an age estimation method using artificially generated data. Image data are artificially generated through 3D information, thus solving the problem of shortage of training data, and helping with the training of the deep-learning technique. Augmentation using 3D has advantages over 2D because it creates new images with more information. We use a deep architecture as a pre-trained model, and improve the estimation capacity using artificially augmented training images. The deep architecture can outperform traditional estimation methods, and the improved method showed increased reliability. We have achieved state-of-the-art performance using the proposed method in the Morph-II dataset and have proven that the proposed method can be used effectively using the Adience dataset.
