본 연구의 목적은 군사작전 지형분석에 활용할 수 있는 오픈소스 GIS SW가 무엇인지를 파악하는 것이다. 야전 군사작전에 있어서 지형분석 또는 지형분석체계가 무엇인지를 살펴본 후 야전 군사작전을 비롯한 다양한 국방분야에서 오픈소스 GIS SW를 도입하여 활용한 선행사례를 살펴보았다. 이를 바탕으로 우리나라 군사작전 지형분석에서 요구되는 환경과 조건을 살펴보고, 8개의 오픈소스 GIS SW의 지형분석에 필요한 기능뿐만 아니라 개발과 및 사용자 커뮤니티, 연계활용성, 개발의 용이성, 발전속도 등 다양한 기준으로 확인하였다. 비교결과 QGIS와 GRASS GIS가 군사작전 지형분석에 장점이 많은 것으로 나타났다. 빠르게 변하는 군사작전 지형분석 여건과 다양한 기능을 활용해야 하는 수요를 고려할 때, GRASS 뿐만 아니라 SAGA, R 등 다양한 오픈소스 SW를 연계하여 활용할 수 있는 QGIS가 유리할 것으로 판단된다.

This study was conducted to find sensitive indicator of food intake and specific food group related to cognitive function and to analyze the pathway among factors affecting food intake and cognitive function of the aged. 179 people over 50 years old were investigated and all the data were analyzed by SPSS 10.0 package. Food frequency was more sensitive indicator to show the relationship between food intake and cognitive function of the aged than the numbers of standard amount of food eaten. Consumption of grains and starch, meat, fish, eggs and beans were strongly related to cognitive function of the aged and intake of vegetables and fruits also have relationship with it. Moreover, the more frequent eating the carbohydrate and the protein, the higher the cognitive level of the aged. Age, education period, income, blood pressure, duration after retirement, frequency of physical activity and BMI were correlated with food intake and cognitive function of the aged. Among them, age and frequency of physical activity were most strongly correlated with food intake, and education period with cognitive function of them. This investigation shows that more stable intake of carbohydrate and protein containing foods need to be supplied to low income aged and the importance of physical activity of the aged must be emphasized with food intake for better life of the aged.

The purpose of this study was to investigate the cognitive differences among the aged who have different living conditions. 91 free-meal receivers and 86 people with stable lives were asked about their living conditions and cognitive function by using K-MMSE. All data were analyzed by SPSS 10.0 package. Free meal receivers had poorer socioeconomic status than the subjects who had stable lives. Cognitive function of free meal receivers was lower than the people with stable lives in the most cognitive factors. Especially age of 50 to 64, pre-aged group, who had been receiving free meals, showed lowest cognitive level than the other age groups. Among 7 cognitive factors, there was the greatest difference in attention and calculation between 2 groups. Percentage of 'conclusive dementia' among the free meal receivers was statistically higher than the people with stable lives and that of 'conclusively normal' was statistically lower in free meal receivers comparing with the people with stable lives. Moreover, socioeconomic factors like income, former job, marital status, housing and education, blood pressure and physical activity were significantly related to the subject's cognitive function.

Due to the continuous change of socio-economic circumstances and dietary pattern, the need to change recommended dietary allowances and the basic food groups has been required. Consequently, there have been six revisions of the Korea RDAs, the national recommanded dietary allowances. I reviewed the six sequences of revisions concerning the basic food groups. Up to the fifth revision, the ranks of the basic food groups were based upon the dietary needs of the people of the perspective era. However, in the sixth revision, there was no rank associated with the food groups, but the food groups were portrayed in a food composition tower that explained their importance and their necessary consumption amounts. I could indirectly observe the dietary pattern of each era by analyzing the basic food groups and the representative foods of each food group. I also studied information of pictorial representations of the basic food groups and compared the items of the representative foods with nutrient analysis table. By observing nutrient analysis table, I analyzed whether the clarified representative foods of the basic food groups are indeed foods that were eaten frequently by people daily.
