산업화가 진행된 세계 주요 선진국들은 의학의 발달과 평균 수명의 증가로 고령화의 위기를 겪고 있다. 인구 고령화에 따라 치매 인구도 크게 증가하였다. 치매 인구의 증가는 국가와 가정의 물질적, 인적 비용을 증가시키고 있다. 이와 같은 사회문제를 해결하고 효율적인 치매 환자 관리를 위한 방법이 필요하다. 관찰 대상자가 치매 증상과 비슷하게 행동한다면 치매를 의심해 볼 수 있다. 본 논문에서는 3축 가속도 센서를 사용하여 대상자의 행위 정보를 수집하고 디지털화한다. 디지털화 된 행위정보를 치매 증상의 행동 패턴과 비교하여 관찰 대상자의 행동이 치매 증상인지 정상적인 활동인지 판단할 수 있는 방법을 소개한다.

This study conducted a survey on the time serial change in the aging ratio and population structure in new towns and their housing complex of Korea and Japan, and revealed the differences in the factors that affect the aging ratio in new towns of Korea and Japan through a comparison of the housing provision of housing complex with a high aging ratio. Rapid aging is underway around the housing complexes that were developed in the beginning of Tama new town in Japan. Agingtends to increase in proportion to the opening time of the housing complex. Rental housing residents of early migration households showed rapid aging because they had generation separation early due to narrow housing. On the other hand, Bundang new town maintains a lower aging ratio and speed than Seoul and Seoul metropolitan area due to the constant influx of student population. On the other hand, aging is more likely to increase in large houses due to the depression of the real estate market.

Due to the change in the demographic structure, the problem of low birth rate and aging population leads to a serious decrease in human resources, and the necessity of introducing foreign workers is increasing. This study believes that the introduction of foreign workforce is the most effective to expand the working-age population in the era of low birthrate and aging, when demographic changes begin in earnest, and to this end, it sought to devise measures to improve the legal system for migrant workers. As a result of this study, first, the legal system for migrant workers should be unified and improved. It is necessary to establish or unify management agencies so that the 「Immigration Control Act」 and the 「Labor Act」 can establish a cooperative relationship. Second, the 「Immigration Control Act」 should be revised to make it easier for migrant workers to find employment. It is necessary to positively review the employment permit system and acquisition of nationality. Third, there should be no equity or discrimination against migrant workers. Under the principle of mutual benefit, employers and migrant workers should not be equally discriminated against. Fourth, the social insurance system must be added to the legal system of migrant workers. Therefore, the legal system should be reorganized so that migrant workers are not discriminated against in various insurance systems including the four major social insurance systems. In conclusion, the problem of low birthrate and aging population has become a serious social problem due to changes in the demographic structure, and the decrease in the possible generation population has reached a level of concern. The importance of migrant workers' employment and work environment is increasing. Nevertheless, related legal and institutional problems still exist, and measures to improve the legal system for migrant workers are needed.

This study aims to understand public perceptions of aging Korean society and related factors in the context of population aging and generational difference. Data are from 1,498 individuals older than 20 who were recruited through the quota sampling technique. Results indicated that the respondents reported less then three as the number of positive aspects of aging Korean society. Among the factors related to population aging, such as knowledge about aging, perceptions about family care, anxiety about later life, and perspectives about generational conflict, anxiety about later life was shown to be negatively associated with perception of aging Korean society across age groups. Respondents 65 and older showed more positive perception about aging Korean society and this association was conditioned by perspectives about generational conflict. Perspectives about generational conflict revealed positive associations with perception of aging Korean society among respondents aged 20-44 and 45-64, while no association was found among those 65 and older. Discussions focused on ways to alter perceptions of aging Korean society and needs for future research on this topic.

지난 1세기동안 전세계적으로 평균수명(출생시의 평균여명)이 약 30년 정도 연장되어 1999년 현재 60세 이상의 고령 인구가 5억8천만 명에 이르렀으며, 2020년까지는 10억 명을 돌파할 것이라고 한다. 이는 같은 기간동안에 전세계적으로 예상되는 인구 증가율이 50％ 미만인 것에 비해 훨씬 높은 75％의 증가로서 전례가 없는 일이며, 모든 정책 입안자들의 즉각적인 주의가 요구되는 문제이다. 한편 우리 나라도 예외일 수 없어, 통계청의 인구추계 자료에 의하면 1969년 948.5 천명으로 3.0％에 불과했던 우리 나라의 65세 이상 고령 인구는 2000년 현재 3,395천명으로 전체 인구의 7.2％에 달했으며, 2019년에는 전체 인구의 14.4％에 까지 이르러 고령사회(aged society)로의 진입이 예상되고 있다.

산업의 발전과 더불어 농업인구는 해마다 감소하고 있으며 농업 연령층은 고령화 현상이 나타나고 있다. 전체 농가인구와 호당 농업인구가 줄어들고 있는데 반해 호당 경지면적은 매년 증가하고 있다. 노동력은 농업생산비의 가장 큰 비중을 차지하고 있고, 농가의 연령층 또한 고령화가 되어가고 있음을 고려해 본다면 농업의 기계화ㆍ자동화의 필요는 절대적이다. 수확은 재배 과정 가운데 노동력, 시간 및 비용이 가장 많이 소요되는 작업이다. 본 연구는 수확용 매니퓰레이터의 개발을 위한 기구학적 분석을 하는 것이다. 구체적인 연구 목적은 매니퓰레이터의 정방향 기구학 및 역방향 분석을 통해 방정식을 구한 후 장치를 작동시켜 반복오차를 측정한 후 이 값을 이론값과 비교하여 검증하도록 하였다.

우리나라는 2002년 초저출산 사회(합계출산율 1.3명 이하)로 진입한 후 합계출산율이 평균 1.2 이하인 상황이 지속되고 있다. 이러한 초저출산 상황이 향후 지속된다면 인구고령화의 사회 경제적 여파가 예상보다 클 것으로 전망된다. 과연 이런 초저출산 추세가 일시적인 것인지 아니면 앞으로 계속 지속될 것인지에 대한 검토가 필요하다. 이에 본 연구는 최근 저출산함정 가설(low fertility trap hypothesis)을 제기한 Lutz, Skirbekk and Testa(2006)의 논의를 소개한다. 그들은 크게 인구학적, 사회적, 그리고 경제적 요인과 같이 3가지 요인으로 구분하여 저출산함정의 존재 가능성을 논하고 있다. 그렇다면 과연 우리나라는 저출산함정에 빠져 있는가? 먼저 고령화 가설의 경우 출생아수와 고령화간 부(-)의 관계가 나타나고 있으며, 최근 이상자녀수가 2.2~2.3명이지만, 실제자녀수는 그 수준을 하회하고 있어 이상자녀수가설도 지지된다. 상대소득가설의 경우, 류덕현(2007)의 연구결과에 따르면 연령 계층 간 상대소득이 출산율에 정(+)의 효과를 보여 상대소득가설이 지지되는 것으로 나타났다. 물론 제한된 영역에서 완벽한 검증이 이루어진 것은 아니지만, 적어도 출산율이 대체수준까지 회복되기에는 어려운 상황이라는 점을 발견할 수 있었으며, 이는 우리나라의 저출산 문제가 얼마나 심각한 수준인지를 재확인시켜준다.

This study aims to analyze the factors affecting consumption inequality in the 10 years following the financial crisis, applying the cohort method on the data for the first to the eleventh wave of the Korean Labor and Income Study produced by the Korean Labor Institute. The study found that consumption inequality increased rapidly immediately following the financial crisis, and then decreased gradually until increasing again from 2005 onward. Analyzed in terms of age-time-cohort effects, there was a significant change in consumption inequality around the age of mid-forties, and the decrease in consumption inequality was smaller in the younger generations than in the older ones. This suggests that as the current younger generations age over time, consumption inequality may become greater. Also, when the factors in population-cohort-age effects from 1998 onward are analyzed, the age effect in consumption inequality becomes smaller, whereas the role of the rising average age due to demographic shifts seems to be increasing. This means that consumption inequality may become a serious problem in the rapidly aging society. Therefore, there is a need to consider ways to bolster social security and to provide further public assistance in the low-income retiree.

It has been a long time since cars had become important means of transportation in human life. Since 1970s, cars have been increasing steadily because of rising individual income and changing lifestyle toward leisure and convenience. The number of cars is just 1.8 per thousand populations in 1970s, however, in 2012, it has increased to 291.15. Forecasting the demand for cars would be useful to plan, construction or management in the field of motor industry, road building and establishing facilities. Our study predicts the demand of cars through estimating the growth curve model. Especially, we include ageing variables to forecasting identifying the effect of ageing on the demand of cars. The main findings are as follows. In 2045, the number of cars is expected to reach 486.8 per thousand populations with passing a primary saturation point at early 2020s. Also, due to effect of ageing, the predicted demand of cars is about 10% lower than in case of which if ageing effect not exist.
