이 연구는 1983년 전국인구이동조사 자료 중 개인사자료를 사용하여 한국인 남녀가 결혼으로 이행해 나갈 때 결혼에 관한 규범 중 연령규범과 순서규범에 의해 어떻게 영향을 받는지를 보고자 하였다. 연령규범은 결혼적령기라는 개념으로 표현되고, 순서규범은 결혼에 이르기 위해서는 어떤 생애과정를 밟아야 하고, 어떤 조건을 충족시켜하는지를 나타내는 것으로 상정하였다. 구체적으로 이 연구에서는 결혼적령기까지 남자와 여자 모두 연령규범과 순서규범을 지키면서 결혼에 이르는 것으로 가정하였다. 결혼적령기가 지나면 남자는 여전히 결혼 전에 안정된 직장을 확보해야 하는 순서규범에 큰 영향을 받지만, 여자의 경우는 결혼직전 경제활동상태에 관계없이 연령규범에 더 큰 영향을 받는 것으로 가정하였다. 자료를 분석한 결과 이 연구에서 상정한 가설 모두 통계적으로 지지되었다. 이는 1983년 자료를 통해 볼 때 한국인의 결혼 및 가족생활에서 남자는 경제적인 능력을 갖추어야 하고, 반면에 여자는 규범적 연령에 보다 더 큰 영향을 받는 것으로 해석되었다.

This study was proposed in obtaining basic data for an intervention programs of the stable child care by identifying the effects of support from the spouse and family on the child rearing among marriage immigrant women. Subjects consisted of 110 marriage immigrant women in Gyeonggi-do in December, 2014. SPSS/WIN 22.0 program was used for ANOVA, Pearson's correlation and multiple regression analysis to figure out burden and efficacy of child rearing through the general characteristics. The increased burden of child rearing was statistically significant with young age, lower level of education, low income and less spending time to raise their children by husband. Additionally, the increased efficacy of child rearing was statistically significant with young age and using two languages. The pressure of the child rearing showed a negative correlation with spouse support, income, and old age. The efficacy of child rearing had a positive correlation with spouse support, spending time to take care of their children by family, and ages. In the regression analysis, the burden of child rearing among immigrant women increased by old age (${\beta}=-2.097$, p<.05) and less time to raise their children by husband (${\beta}=-2.165$, p<.05). It is important to provide spouse and family support to encourage desirable child rearing behavior. These results may provide to improve intervention programs for child rearing among marriage immigrant women.

This study has been done to understand the relationship between age norms and negative perception on older workers, and to find out moderating effect of recognition of employment welfare services in those relationships. And the purpose of this study is to suggest alternative ways to improve pessimistic perception on older workers, which is basal ageism. For this purpose, the survey has been conducted with 630 participants, who were 20 years old and over and lived in 15 different provinces. The collected data has been analysed by using SPSS Win 18.0. The results as followed: first, there were significant differences of negative perception on older workers among provinces(metropolitan areas, small towns, and rural areas); second, age norms significantly influenced on pessimistic perception on older workers; third, moderating effect of recognition of employment welfare services has been verified. These results suggest that it is necessary to promote people to take a flexible attitude toward older adults using media broadcasting and promotion of employment welfare services. Public and private cooperation should be needed to change people's negative perception on older workers. Lastly, programs, which are appropriated and tailored in specific provinces, improving awareness of older workers should be required.

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.

A methodology for determining age by otolith of small yellow croaker, Pseudosoiaena polyactis Bleeker, was developed. A thin section method was chosen to be suitable for age determination because the otolith had a three-dimensional shape and thus it was not possible to read the otolith rings on the surface. The clear rings were identified on the vertical-axis cross-sectioned otoliths. The total length-total weight relationship and the growth parameters were estimated with error structure to endow with accuracy. In the relationship between total length and total weight, a multiplicative error structure was assumed because variability in growth increased as a function of the length, and the estimated equation was $W=0.0049L^{3.2153}$. The variability in growth was constant as a function of the age, revealing an additive error structure. The von Bertalanffy growth parameters were obtained from a nonlinear regression as $L_{\infty}= 37.11cm, K=0.20/yr and t_0=-1.88.$

The purpose of this study was to estimate occlusal tooth wear and bruxism severity in TMD patients, and evaluate the effectiveness of the present age estimation method by occlusal tooth wear in TMD patients. Takei's age estimation method was applied to 163 subjects(56 controls, 107 TMD patients). The author analyzed the degree of occlusal tooth wear from the difference between estimated age and actual age. The obtained results were as follows: 1. In all age group, occlusal tooth wear in TMD patients is higher than those in asymptomatic controls. In 20's age group, a statistically significant difference was found. 2. In both gender, occlusal tooth wear in TMD patients is higher than those in asymptomatic control. In male, a significant difference was found. 3. Occlusal tooth wear in TMD patients with bruxism is significantly higher than that in control. 4. We found no significant difference in bruxism severity and occlusal tooth wear among the RDC/TMD subgroups. 5. Application of Takei's method would be still useful for age estimation in Korean. In case of age estimation of TMD patients using occlusal tooth wear, evaluation of the bruxism severity and appropriate correction according to age, sex and difference of geographical location should be considered.

Currently, as construction projects in Korea are becoming larger and more complex, the hazard rate of the construction industry is steadily increasing, contrary to other industries. This can be seen as an indication that the safety technology and safety consciousness of construction workers are insufficient compared to the improved construction technology. In addition, due to the characteristics of the construction industry based on manpower, most accidents appear in conventional forms such as fall and trip due to human errors. Therefore, analyzing the relationship between the characteristics of human resources and accidents and establishing detailed safety plans is an essential part of reducing construction accidents. In this study, a correlation analysis was conducted using 62,805 cases of construction accident cases over 3 years to derive the characteristics of accident occurrence focusing on the age of workers. As a result of the analysis, the relationship between the age of workers and the frequency and severity of accidents for each accident type was derived, focusing on the top 10 accident types.
