농촌사회의 당면한 문제는 농촌인구의 극소와 잔존인구의 성·연령별 인구구조의 왜곡에서부터 제기되므로 농촌인구의 변화추세를 검토하였다. 그리고 최근 군부로의 전입과 전출 인구를 비교하여 최근 농촌으로의 인구회귀현상의 실태를 분석하였다. 끝으로 농촌의 인구실태를 파악하기 위하여 실시한 농촌마을 조사자료를 분석하여 농촌으로 전입하는 인구의 영향을 밝혔고, 특성별 농촌마을의 장래를 예측하였다. 군부의 인구는 도시로의 인구전출이 지속되면서 젊은 연령층과 영유아의 인구구성비가 낮고 노인연령층이 두텁게 되었다. 산업화 이전단계인 1960년 군부의 0∼4세 인구구성비는 시부보다 높았으나 농촌인구의 도시전출이 누적되면서 1975년부터 시부보다 낮아졌다. 그러나 1995년의 군부 0∼4세 인구구성비가 6.2%로 5년전보다 상승하여 시부와 차가 감소되었다. 또한 1980년대 후반에 시부에서 군부로 이동하는 인구의 연령별 구성에서 20∼34세에 총이동인구의 51.8%가 집중되어 있었으며, 이들의 교육수준은 시부로의 전입인구보다 오히려 높았다. 이러한 사실은 농촌사회의 변화로 나타내게 될 것이다. 그러나 순수농촌마을이라고 할 수 있는 보은군의 농촌마을과 원래 농업중심 마을이었으나 최근에 급속히 변하고 있는 파주군의 근교농촌마을의 인구구조를 비교한 결과 최근의 농촌인구구조의 변화와 젊은 연령층의 군부로 전입하는 현상은 일부 농촌, 특히 근교농촌의 변화에 의한 현상이지 전체 농촌인구형상의 변화라고 할 수 없었다. 이들 마을 실태조사에서 밝혀진 마을 인구구조의 특성에서 우리는 산업화나 도시의 영향을 받지 않는 순수농촌마을은 거주민의 노령화가 극단적으로 진행되어 마을 자체의 존속이 어려워지는 반면에 근교 농촌마을은 농촌의 성격이 흐려지면서 도시화 내지 산업화가 진행되는 것을 알 수 있었다. 않는 임신, 성감염증, 그리고 인공유산 등의 위험으로부터 제대로 보호를 받아야 한다고 믿는다.보완하는 벤치마크 기능도 수행하기 때문이다.국의 대외 이미지 개선을 위한 적극적인 PR활동과 기업의 최고경영자 차원의 로비활동 추진으로 대미(對美)로비체제를 적극적이며 능동적으로 수행할 수 있도록 하여야 한다.였고, W.X 조국은 동쪽으로 265.2m, W.Y 조국은 북쪽으로 279.5m, 그리고 X.Y 조국은 북서쪽으로 224.3m 편위하여, Loran - C 위치가 GPS 위치보다 약 250m 더 편위 된 것을 알 수 있었다.경우 본 논문에서 계산한 각 침로교각에 대한 최소피항개시거리와 안전피항개시거리을 미리 염두해 두고 피항조선을 하게 되면, 감각에 의한 조선방법으로 야기되는 충돌해난사고를 지양 할 수 있으리라 사료된다.만도에 따른 유의적인 증가를 (p<0.05)보여주었으나 여자의 경우는 유의적인 차이가 없었다.

This study surveyed the actual status of reclamation areas in South Pyongan Province, North Korea, using satellite images and literature to survey the creation date, area, and length of the embankment of the reclamation areas. The reclamation areas in South Pyongan Province were created in three stages, with the first stage completed in the late 1970s or early 1980s, the second stage in the late 1980s or early 1990s, and the third stage in the 2000s. The total area of the reclamation areas is 105,570 hectares. The land cover of the reclamation areas is as follows: agriculture (50.5%), saltern (29.5%), water bodies (13.6%), foreshore (12.4%), grasslands (3.0%), bare land (0.4%), facility (0.1%), and forests (0.1%). The study also found that the NDVI values of the reclamation areas vary depending on the location. The NDVI values of the Gwiseong and Namyang reclamation areas are low, while the NDVI values of the Samcheonpo and Jigdongbaedali reclamation areas are high. The study found that the NDVI values of the reclamation areas are correlated with the land cover of the reclamation areas. The study's findings can be used to understand the development direction and regional characteristics of the reclamation areas in South Pyongan Province. The study's findings can also be used to develop policies and plans for the sustainable development and utilization of the reclamation areas in South Pyongan Province.

A stream purification system was applied to the upper reaches of the Masan Reservoir to improve the water quality. This system consisted of two channels which were constructed on both sides of the stream, one side packed with crushed gravels and the other with plastic filter media. The system operated under low pollutant concentrations and high hydraulic loadings during a dry season to avoid clogging of the filter media. Removal rate and efficiency of chemical oxygen demand (COD) in the channel packed with crushed gravel were $14.8g/m^3/d$ and 11.5%, and for the channel with plastic filter media, $50.1g/m^3/d$ and 13.5%, respectively. Removal efficiencies of total phosphorus (T-P) were 6.6% (gravel) and 10.0% (plastic media). These results indicated plastic filter media having relatively high specific surface areas were more efficient than crushed gravels in removing pollutants. However, due to low influent water quality during dry season, the removal efficiencies were low. The proportion of nitrate nitrogen to total nitrogen (T-N) of the inflow was high but, as the system operated under aerobic condition, nitrate nitrogen could not denitrified. Accordingly, total nitrogen was not attenuated with this system. To improve the reservoir water quality effectively, this system should be able to treat the storm runoff containing higher pollutant loadings. When the filter materials are clogged by the storm runoff instead of backwashing, it would be more efficient to replace them, Therefore, the use of natural materials which are light, easily obtaining and replaceable, and have high specific surface areas is recommended.

In this study, a functional vegetable garden model is proposed for vegetable gardening users in urban areas to grow different vegetables for various purposes. H vegetable garden user(uneducated) and Y vegetable garden user(educated) urban vegetable gardening users were provided with the functional vegetable garden model and allowed to manage their allocated gardens directly. As the issues raised by the field work and its associated solutions were investigated, the opinions from each group were compared and analyzed. The conclusions are as follows. First, according to the usage survey for vegetable gardening, both groups responded that they had mostly cultivated vegetables. Second, with regard to the kinds of vegetables cultivated in autumn, both groups chose the vegetables required for producing Kimchi. Third, both groups responded that their interest in growing various plants was the major motivation to start gardening. Fourth, regarding the inclusion of flowers and herbs in the functional vegetable garden, more than 90% of the members of both groups responded that the level of the inclusion was appropriate or could be higher.

The study is a comparative analysis of the differences in economic activities of two rural villages near the city. It is the general notion that rural villages near large cities lose the characteristics of traditional rural villages and change the areas with urban characteristics due to the influence of urbanization. The survey also showed that Munho 4-ri and Jeongbae 1-ri in Gyeonggi-do have urban characteristics, such as population growth, agricultural activity reduction and non-agricultural activity increase, and community activity reduction. However, they also found that there were important differences in the future development patterns of the two villages. In other words, the reasons and purposes of migration of people moving to the two villages, the differences in the system of economic activity in the villages, and the differences in community cooperation are emerging. Therefore, the study shows that policies to develop rural villages near cities need to be implemented differently based on the characteristics of those villages.

Gaining an accurate 3D stream geometry has become feasible with Unmanned Aerial Vehicle (UAV), which is crucial for better understanding stream hydrodynamic processes. The objective of this study was to investigate series of filters to remove stream vegetation and propose the best method for generating Digital Terrain Models (DTMs) using UAV-based point clouds. A stream reach approximately 500 m of the Bokha stream in Icheon city was selected as the study area. Point clouds were obtained in August 1st, 2023, using Phantom 4 multispectral and Zenmuse L1 for Structure from Motion (SfM) and Light Detection And Ranging (LiDAR) respectively. Three vegetation filters, two morphological filters, and six composite filters which combined vegetation and morphological filters were applied in this study. The Mean Absolute Error (MAE) and Root Mean Square Error (RMSE) were used to assess each filters comparing with the two cross-sections measured by leveling survey. The vegetation filters performed better in SfM, especially for short vegetation areas, while the morphological filters demonstrated superior performance on LiDAR, particularly for taller vegetation areas. Overall, the composite filters combining advantages of two types of filters performed better than single filter application. The best method was the combination of Progressive TIN (PTIN) and Color Indicies of Vegetation Extraction (CIVE) for SfM, showing the smallest MAE of 0.169 m. The proposed method in this study can be utilized for constructing DTMs of stream and thus contribute to improving the accuracy of stream hydrodynamic simulations.
