  • Rapidly shifting to aging population is a global trend, and one of the challenging issue for the government, business and welfare perspective. In this paper, we focus on application potentials of information and communication technologies, to capture the insights for effectively coping with population aging issue. As the research for silver ICT field is rather limited, we adopt case study research method to extract policy implications and related foundation research agenda. As such, we first investigated comprehensive up-to-date trends, cases for innovative ICT applications, and policy initiatives mainly from the works of OECD nations. With reference to the review findings, we propose policy implications and guidelines for ICT innovations which contributes better quality of life and continuing job opportunities for silver population. The results provides insights for government policy initiative and further research in silver ICT area.

  • The trend towards ageing populations has been observed over many years in Europe and the US but has accelerated significantly in developed countries in Asia including Japan and South Korea. In the latter country the elderly population (65+) has increased 5-fold between 1960 and 2000 and this group will comprise 40% of the population by 2050. This creates a new socio-economic group with specific demands and considerable spending power. As ageing occurs a range of changes occur in the body that can be moderated by adjustments in nutrition. A significant body of evidence points to changes in the balance of glutathione synthesis and utilisation as people age. Glutathione is tile most important natural anti-oxidant of the body and the amounts present can become limited by available cysteine in the diet. A cysteine-enriched peptide product, Cysteine Peption$^{TM}$ has been developed by DMV International for dietary supplement and food applications. A qualitative consumer trial has indicated benefits including improved sleep and more energy. Animal and clinical trial will be described that provide indications on bioavailability and possible mechanisms of action of Cysteine Peption$^{TM}$ with particular focus on the ageing population.

  • The steady rise in life expectancy resulting from progress in medical science and economic growth and improved living conditions is responsible for large and increasing-number of older peoples in our country. The older peoples who are increasing make up a large percentage of our total population. Now a day the percentage of older people 60 and 65 years old over compose around 8.7% and 5% of the total population in each. In spite of such a rapidly increasing trend of older population, there has had no provisions for elderly welfare in our country. The reason why some children do not want to take care of their older parents, and the other is the lack of elderly welfare, are responsible for large and increasing anxiety of livelihood and alienation to the number of older peoples. As mentioned above, especially studying Swedish elderly welfare model of many developed countries, it intend to provide many of the useful materials to make the elderly welfare systems in our country. The main research for Swedish elderly welfare are as follows : (1) Old age pension systems (2) Social service systems (3) Health care service systems (4) Housing care service systems.

  • Objectives: This study is a cross-sectional study to investigate the frequency of humidifier and humidifier disinfectant usage in the general population. Methods: A questionnaire was applied to 94 subjects (46 male, 48 female) from the general population of Gyeonggi Province. The questionnaire consisted of 3 scales (general characteristics, 5 items about humidifier usage, 5 items about humidifier disinfectant usage). Results: Thirty-five (37.2%) of the 94 subjects use a humidifier and humidifier disinfectant usage was found to be 18.1%. The frequency of humidifier usage is 4.8 times per a week and the humidifier disinfectant usage is 2.4 times per a week. Humidifier usage rate was highest in January. and then tended to rise gradually from October. Conclusions: Although this study population was not representative, we can say that approximately 50 percent of the humidifier users use a humidifier disinfectant and the trend of using a humidifier has shown seasonality.

  • 부산대도시의 공간구조와 그 문제들에 관심을 가진 많은 도시 학자들과 연구자들이 부산대도시 공간구조에 대한 관리의 필요성을 오랫동안 제기하였다. 그래서 본 연구의 목적은 1993년, 2001년의 기간 동안의 인구밀도, 고용밀도, 지가로 부산대도시의 공간구조의 동적인 변화를 알아보는 것이다. 본 연구의 중요한 결과들은 다음과 같다. 도심의 인구유출을 경험하는 동안, 주변부는 지속적으로 성장하였다. 중앙동은 인구 잠재성의 높은 접근성을 가졌다. 그러나 그 접근성은 1993년 이후 줄어들고 있다. 부전동은 2000년까지 인구가 증가하는 경향을 보이나 그 이후 년부터는 인구가 감소하였다. 그사이에 주변부는 높은 접근성으로 인구가 증가하였다. 그래서 부산의 공간구조가 다핵도시로 바뀌었다. 이 현상은 기존의 도심에서부터 자발적인 인구분산을 일으키게 되었다. 지가 변화에서는 부산 도시화의 분포패턴을 보여준다. 부산의 가장 높은 지가는 CBD에서 나타나며, 부산의 발전은 남북 띠를 따라 나아가면서, 서부산 지역에 영향을 주었다.

  • 본 연구는 1820년부터 2006년까지 세계인구와 세계 산출량인 국민소득의 수준과 표준화 추이 및 패널 분석을 바탕으로 인구와 산출량이 부(-)의 관계라는 맬서스 가설을 재조명하였다. 실증분석 결과에 의하면 세계경제에서 맬서스 국면이 1900년부터 1994년의 기간 동안 나타났으며, 개별 국가의 경제성장 단계도 맬서스 국면을 경험했던 것으로 분석되었다. 그러나 1995년 이후 인구가 큰 폭으로 감소하고, 산출량이 급격하게 증가하면서 맬서스 국면은 유효하지 않은 것으로 나타났다. 이런 현상은 급격한 기술진보를 바탕으로 오히려 산출량이 기하급수적으로 증가했지만, 인구는 출산율 감소와 같은 사회적 현상으로 인해 큰 폭으로 감소한 것에 따른 것으로 보인다. 인구가 생산활동에 기여하는 방식이 양적 증가보다 자본이 체화된 인적 자본으로 전환된 것도 또 다른 요인이라고 볼 수 있을 것이다. 또한, 인구의 수요 창출 효과도 함께 고려한다면 인구의 경제적 역할은 지속적인 진화 과정을 거치게 될 것이다.

  • 이 연구는 코호트 변화율법을 이용하여 우리나라 산촌지역 인구변동의 특성을 분석하고 장래 산촌인구를 추계한 것이다. 분석대상이 되는 산촌은 산림청에서 지정한 산촌진흥지역으로, 산림면적 비율 70% 이상, 인구밀도 111인/$km^2$, 경지면적 비율 21% 이하인 읍 면으로 정의한다. 산촌의 인구변동 특성을 살펴보면 지난 20년 간 산촌 인구는 급격히 감소하였고 노령화 지수는 상승하였다. 연령별로는 10~30대 젊은 층의 인구 유출이 많고 40대 이상 장년층의 유입이 증가하였다. 젊은 세대 인구가 감소하는 것은 교육과 취업을 위해 도시로 이동하는 경우가 많기 때문이며, 장년층 인구 증가는 귀농 귀촌에 대한 관심 증대의 영향으로 생각된다. 이러한 추세가 지속된다면 산촌인구는 2030년에 68만 명, 산촌의 노령화 지수는 1,035로 상승하여 국토의 균형 발전과 산림의 지속가능한 경영에 문제를 초래할 것이다. 따라서 산촌경제 활성화와 안정화를 위한 정책적 개입이 필요하다.

  • Land-use in northern Cheongju region is changing rapidly because of the increased interactions of human activities with the environment as population increases. Land-use change detection is considered essential for monitoring the growth of an urban complex. The analysis was undertaken mainly on the basis of the multi-temporal Landsat images (1991, 1992 and 2000) and DEM data in a post-classification analysis with GIS to map land-use distribution and to analyse factors influencing the land-use changes for Cheongju city. The area of each land-use category was also calculated for monitoring land-use changes. Land-use statistics revealed that substantial land-use changes have taken place and that the built-up areas have expanded by about $17.57km^2$ (11.47%) over the study period (1991 - 2000). This study illustrated an increasing trend of urban and barren lands areas with a decreasing trend of agricultural and forest areas. Land-use changes from one category to others have been clearly represented by the NDVI composite images, which were found suitable for delineating the development of urban areas and land use changes in northern Cheongju region. Rapid economic developments together with the increasing population were noted to be the major factors influencing rapid land use changes. Urban expansion has replaced urban and barren lands.

  • The effect of transinoculation of goat rumen liquor into sheep rumen on mimosine toxicity was studied. One adult Kutchi male goat having higher mimosine degradation capacity than sheep was gradually adapted to Leucaena leucocephala (Leucaena) leaves by feeding increasing level of eucaena leaves supplementation for 1 month. Six Bharat Merino rams (12-18 months of age) were divided into two equal groups with (group I) or without (group II) infusion of 200 ml of goat rumen liquor per animal. The mimosine degradation in groups I and II were 3.04 and 2.31; 3.90 and 3.73 mg per day per 10 ml rumen liquor respectively after 1 and 2 weeks of leucaena feeding leaves. Total rumen bacterial population in RGCA medium and in a selective medium containing iron showed an increasing trend in both groups, while the bacterial population growing in the presence of cellulose showed a decreasing trend. Animal performance data did not show any adverse effect. Results revealed that transinoculation of rumen liquor from leucaena leaves adapted goat to sheep rumen did not help to improve mimosine degradation in the sheep. The sheep transinoculated with goat rumen liquor displayed no in vivo improvements in nutrient utilization vis-a-vis mimosine metabolism.

  • The agricultural population, the farming, the agriculture of our country has been decreased more rapidly than those of other countries. Also, the changing speed of the rural village in Korea has shown a similar trend. By considering the urbanization process and migration state caused by the economic growth and the increasing level of relative poverty in comparison with the urban area, it has been necessary to go through the impoverishment and slum-orientation of the rural area. In our country, the rural village became old age. So, the collapse is predicted to a population shortage if such trend is continued in the village society. according to investigate, Many urban peoples have opinion that migrates to a farm village. but those not migrate to rural community. The mainly reason is low life environment. therefore it is need the plan that the urban people migrates to a rural village, and must have the plan to be engaged in the agriculture. lt was the rural-fishing New Town development project that started in 2009 for 30~40 years's urban people. This study is about characteristic and improvement of Rural-Fishing New Town development project.
