To estimate the usability of resident register for the statistical purpose this study compares resident register with census data. The comparison shows that the differences between resident register and census data are closely related with life cycle. Among the aged the incorrect registration is supposed as the main cause for the difference, while among the other age groups the problems rise mainly from their social and economic activities. Especially among the age group between 15 and 24 level of the difference is very high, which results from university entrance and employment. This result confirms the importance of the comparison between these data according to age groups. The structural character of this difference suggests that the difference can be explained and reduced through policies.

Although previous studies have found that social participation activities are related to older people's life satisfaction and health status, the rate of social participation activities among older people is still low. The current study examined the relationship between age identity and social participation activities among older people and the extent to which this relationship differs by gender. Secondary data from the Survey of Living Conditions of Korean Older Persons were used to test the research hypothesis. Hierarchical multiple regression models were tested using a nationally representative sample of 10,451 community-dwelling older persons aged 65 and above. Older people who have older age identity were less likely to involve in social participation activities than those who have younger age identity. However, this relationship was only significant for older women. The findings suggest the need for attention to age identity and gender differences when promoting social participation activities.

The purpose of this study was to compare the physical and psychological functioning by sex, weight and age in Judo athletes. The 124 participants; high school students, college students, and team players. They used physical tests to measure physical examinations by self-describing Knee injury and Osteoarthritis Outcome Score test, Foot and Ankle Outcome Score test, and Oswestry Disability Index, and psychological tests such as Profile of Mood Test, Athletes' Self-Management Questionnaire, and The Athletic Coping Skills Inventory-28, to examine the effects of physical and psychological functions of sports athletes. The physical tests of sex showed differences in knee and back, psychological tests of sex showed differences in mood state, self-management, and athletic coping skills. As a result of physical examination by weight, there was a difference in knee pain and sports items, psychological tests showed that there was a significant difference in mood state except for vitality. Physical examination by age showed differences in knee, ankle, and back. As a result of age-based psychological test, mood state test showed difference in all items except tension and vitality. There was a significant difference only in the items of physical management in self-management test. The results of this study are expected to be used as a basic data for sports injury training and medical technology development by sex, weight and age of Judo athletes.

Age estimation is fundamental and important in personal identification with forensic medicine and dentistry. Recently, a lot of studies using various part of the body have been done for age estimation. Age estimation with teeth is the most significant method comparing ones with other part of the body. Gustafson method and Johanson method using postmortem teeth have been authorized in accuracy and systemization and used domestically and internationally. The verification of the accuracy in above methods had been tried many times but it is still rare in Korea. Fifty-nine teeth(incisors, canine, premolars and molars) which were extracted due to periodontal diseases or orthodontic problem were collected. Present study is to 1) compare the accuracy of estimated age in applying Gustafson method and Johanson method to the teeth in Korea, 2) compare and analyze the correlation with results using Gustafson method and Johanson method by age, gender, maxilla - mandible and anterior - premolar - molar. Teeth were embedded in resin and sliced and then examined each one using Gustafson method and Johanson method. The results are as follows: 1. Actual age was a significant difference in estimated age by Johanson method. Actual age was a significant correlation in estimated age by Gustafson method and modified Johanson method. Modified Johanson method was more significant than Gustafson method. 2. In estimated age by Gustafson method, Johanson method and modified Johanson method, there was no significance with actual age by location and gender. 3. In estimated age by Gustafson method, Johanson method and modified Johanson method, there was significance with actual age by age group. Finally, Gustafson method and Johanson method can be used in Korea. To make more accurate verification, however, it needs more specimen and postmortem teeth. Johanson equation proposed by himself has to be developed by further studies.

This paper aims to empirically analyze the factors of difference in trust level for Internet-only bank by age groups. The purpose of this study is to provide clues and a research data in developing differentiation strategies that can increase consumer's trust by age group. In this study, above all, the financial consumer group was divided into the 2030s and 4050s based on age. The study explored the trust determinants of the two groups and compared the differences between the two groups using a multi-group analysis method. As results, in all age groups, financial consumer's trust was seen as a determinant of convenience, security and benefit of financial transaction costs. The difference of the determinant of trust between 2030s and 4050s occurred in the factor of benefit. Moreover, it reconfirmed that consumer's trust is later strongly extended to relationship commitment. These findings suggest that trust is of paramount importance to the Internet-only bank, whose market competition will intensify in the future.

근래 우리나라에서도 평균수명이 길어져 노동의욕이 있는 중고령자가 증가하는 한편, 출산율이저 하되어 젊은 근로자의 수가 감소되고 있다. 통계청의 인구통계과의 추계에 의하면 2000년에는 60세 이 상이 총인구에 점하는 비율이 10.7%, 65세 이상은 6.8%가 되고, 2020년에는 60세 이상이 19.5%, 65세 이 상도 12.5%에 도달한다는 것이다. 인구노령화로 인한 고령화 사회에 대한 준비를 서둘러야 할 때라고 생각된다. 또 고령화 사회로 되면 젊은 연령층의 경제적 부담이 증가되므로 중고령자의 노동인구를 이대 로 방치해 두는 것은 국가적으로나 사회복지적으로나 불경제라고 할 수 있다. 그런데, 문제가 되는 것은, 중고령자를 취업시키는 것이 오히려 사회의 생산성을 저하시키거나 경제적으로 불리하게 되어서는 안되는 것과 중고령노동자 자신의 안전을 확보해야 하는 것이다. 이러한 문제를 해결하기 위해서는 고용에 있어 서 어떠한 점에서 중고령노동자에게 특징과 문제가 있는가를 분명히 할 필요가 있다. 고령자는 청년자 보다 노동능력이 떨어지는 특징과 문제가 있는가를 분명히 할 필요가 있다. 고령자는 청년자 보다 노동능력이 떨어지는 경향이 있지만 개인차도 크고 고령자 중에는 청년자의 기능에 비교해도 뒤떨어지지 않는 자도 있다. 연령만으로 노동능력을 판정하는 것은 적절한 방법이라고 할 수 없다. 문헌에 의하면 역연령(chornological age)이 25세의 경우, 생리적 연령은 23세에서 27세로 4년 차이가 있다고 한다. 이러한 생리적 연령의 차이는 역연령이 더해감에 따라서 점차 크게 되어 역연령이 45세에서는 12년, 80세 에서는 20년이나 된다는 것이다. 이것은 인간에 있어서 시간적 경과를 나타내는 역연령 이외에 신체적 기능연령(functional age)가 있다는 것을 의미하는 것이다. 한편, 생산현장에서는 자동화, 기계화가 진보되어 육체적인 노동이 경감된 결과, 중고령자라도 할 수 있는 작업이 많아지고 있다. 또, VDT (Visual Dislay Terminal) 작업과 같은 정보처리 작업의 수요가 증가하여 그 인재의 부족이 지적되고 있다. 따라서 중고령자의 기능을 조사하여 어떠한 작업에 적합한가를 판단하는 것이 중요한 과제로 되었다. 그러나 노동에는 많은 기능이 관여 하고, 그 내용에 따라서 요구되는 기능이 서로 다르기 때문에 노동적응능력의 기본적인 기능으로 보여지는 것에 좁혀서 작업능력의 연령증가 변화에 대하여다원적 평가를 하는 것이 실제적이라고 할 수 있다. 따라서 본 연구에서는 인간이 가지고 있는 다수의 기능중에서 수지교 치성과 연령증가와의 관계를 조사한다. 만약 연령증가 만으로 수지교치성을 평가 할 수 없는 경우에는 어떠한 요인이 수지기민성의 변화에 영향을 미치는가를 검토한다.

Recently, adipose mesenchymal stem cells (AdMSC) that are similar to bone marrow MSC and blood derived MSC are thought to be another source for stem cell therapy. However, the diseases that can be applied for stem cells therapy are age-dependent degenerative diseases. Accordingly, the present study investigated the growth and differentiation potential to neural cells of human AdMSC (hAdMSC) obtained from aged thirty, forty and fifty. The growth of cells and cell viability were measured by passage and neural differentiation of hAdMSC was induced in neural differentiation condition for 10 days. Our results demonstrated that cell number, viability and morphology were not different from hAdMSC by age and passage. Immunofluorescence analysis of neural cell marker (TuJ1, NSE, Sox2, GFAP or MAP2) demonstrated no significant differences in neural cell differentiation by age and passage. As the number of passage was increased, the mRNA level of MAP2 and Sox2 was decreased in hAdMSC from age of 50 compared to hAdMSC from age of 30. In conclusion, the present study demonstrated that ability of neural cell differentiation of hAdMSC was maintained with ages, suggesting that autologous stem cells from aged people can be applied for stem cell therapy with age-dependent neural disease with the same stem cell quality and ability as stem cell derived from young age.
