The development of logistics technology due to the 4th Industrial Revolution and logistics 4.0 has changed the logistics environment from offline to online, and the growth of the online market has accelerated due to the recent increase in non-face-to-face delivery due to COVID-19. Such growth in the online market has expanded the logistics market for delivery, and contributes to creating an advanced logistics ecosystem as last mile services and logistics technologies begin to grow together. As traffic and environmental problems arise as a result, interest in transportation means of cargo increases, and changes to cargo electric vehicles and delivery cycles are being considered. However, since mass transportation of transportation focused on terminal delivery such as cargo electric vehicles and delivery cycles is limited in handling large quantities in urban areas, methods for efficiently transporting cargo while considering the environment are being devised. In order to solve such environmental problems and increase the efficiency of logistics delivery in urban areas, technologies using underground spaces based on existing urban railroads are being developed. In this study, a study was conducted on the establishment of evaluation criteria for selecting a test bed, which is a space for applying the system.

Most studies on regional economic impact have utilized employment or employment income data. Recently, a few scholars have noticed the importance of nonemployment income sources in urban economies. Using decennial census data on Arizona towns from 1970 to 1990, this paper first examines the increasing importance of nonempolyment income sources in urban economies and the associations of nonemployment income sources with elderly population and metropolitan location. Then, this paper investigates the impact of nonemployment income on urban growth in the framework of economic base model. The regression results show that the impact of nonemployment income is significant in the increase of nonbasic income and becomes greater over time, and that the impact of transfer over time, and that the impact of transfer income on nonbasic income of transfer income on nonbasic income is stronger in smaller towns and the impact of investment income is stronger in larger towns.

We present an analysis of urban development and growth with reconnaissance satellite photographs of Columbus metropolitan area acquired by the Corona program in 1965. A two-dimensional polynomial linear transformation was used to rectify the photos against United State Geological Survey (USGS) Large-scale Digital Line Graph (DLG) data georeferenced to Universal Transverse Mercator (UTM) coordinates. The boundaries of the Columbus metropolitan area were extracted from the rectified Corona image mosaic using a Bayesian approach to image segmentation. The inferred 1965 urban boundaries were compared with 1976 USGS Land Use and Land Cover (LULC) data and boundaries derived from 1988 and 1994 Landsat TM images. The urban area in and around Columbus approximately doubled from 1965 to 1994 (${\sim}110%$) along with population growth from 1960 to 1998 (${\sim}50%$). Most of the urban expansion results from development of residential units.

The relationship between air temperatures and the fraction of urban areas (FUA) and their linear regression equation were estimated using land-use data provided by the water management information system (WAMIS) and air temperatures by the Korea Meteorology Administration (KMA) in the Seoul metropolitan area (SMA) during 1975 through 2000. The future FUA in the SMA (from 2000 to 2030) was also predicted by the urban growth model (i.e., SLEUTH) in conjunction with several dataset (e.g., urban, roads, etc.) in the WAMIS. The estimated future FUA was then used as input data for the linear regression equation to estimate an annual mean minimum air temperature in the future (e.g., 2025 and 2030). The FUA in the SMA in 2000 simulated by the SLEUTH showed good agreement with the observations (a high accuracy (73%) between them). The urban growth in the SMA was predicted to increase by 16% of the total areas in 2025 and by 24% in 2030. From the linear regression equation, the annual mean minimum air temperature in the SMA increased about $0.02^{\circ}C$/yr and it was expected to increase up to $8.3^{\circ}C$ in 2025 and $8.7^{\circ}C$ in 2030.

본 논문은 창조산업이 도시성장전략으로 무차별적 수용되어야 하는가라는 문제의식에서 시작하여, 우리나라 창조산업의 불균등 성장과 지리적 분포 특성 고찰을 목적으로 한다. 주요 결론 및 시사점은 다음과 같다. 첫째, 높은 전문화, 개인의 재능(talent) 중시, 약한 경로의존성 등의 속성을 갖는 창조산업은 순위규모법칙에서 시사하는 것보다 수위 도시로의 편중이 더욱 두드러지며, 인구와 전산업에 비하여 높은 탄력성을 보인다. 둘째, 창조산업은 서울 및 서울 인접 도시들의 동반성장을 통해 불균등 성장 추세를 강화하고 있다. 셋째, 광역시는 창조산업 성장에 주도적 역할을 수행하지 못하고 있으며, 지방 중소도시들의 창조산업 성장은 공간적 연계가 없는 확률성장(random growth) 형태를 보인다. 넷째, 기존 경제기반에서 창출되는 가치가 높은 지역은 창조산업보다 기존 산업기반을 유지하는 것이 도시성장에 도움이 된다.

최근 토지이용 변화에 관한 다양한 연구가 진행되고 있으며, 그 중에서 셀룰라 오토마타(Cellular Automata, CA)를 이용한 연구방법이 도시성장에 많이 활용되고 있다. CA는 셀 상태가 전이규칙에 따라 새로운 시점의 상태로 변하는 연산을 반복한다. 또한 퍼지-AHP를 이용하여 정보 손실을 최소화하고, 유연한 도시성장 모델링을 유도할 수 있다. 그러나 AHP의 경우 가중치 도출까지 의사수렴 작업이 반복되어야 하는 어려움이 있다. 그리고 셀룰라 오토마타를 이용한 시뮬레이션은 많은 연산 모델링이 필요하고, 도출된 데이터 관리 및 일정 기준 시점마다 일치성을 검증하여야 한다. 이에 본 연구는 변수에 상대적 가중치를 부여하는 AHP 단계부터 셀룰라 오토마타를 이용한 도시성장 및 검증과정을 자동화하여 부산시 도시성장을 분석하고 예측하였다. 이를 통하여 도시성장 모델링의 복잡성과 반복성 문제를 개선할 수 있다. 또한 검증과정 부분을 통해 유용성 높은 모델링을 할 수 있으며, 작성된 모듈을 사용하여 이와 유사한 사례 연구에 적용할 수 있다.

This study is carried out to find the most optimal soil-plant combination in the urban agriculture by analyzing the association of soil base material which is being used in the urban agriculture with the growth of plants. 4 types of easily purchased soil (bed soil(A), animal vermicast soil(B), earth worm soil(C) and matured compost(D)) verified in aspects of effect and safety of soil in terms of growth of crop is selected as experimental soil and B, C, D type soils are mixed with granite soil at the ratio of 7 : 3. And granite soil(E) is set as a controlled soil and is compared to verify the effect of the experimental mixed soil. Herbaceous plants are classified into the fruit vegetables (Lycopersicon esculentum Mill. and Capsicum annuum L.), leafy vegetables (Brassica campestris L. ssp. Pekinensis and Lactuca sativa L.), medicinal vegetables (Chrysanthemum zawadskii var. latilobum and Liriope platyphylla F. T. Wang & T. Tang). The results of comparison of growth of herbaceous plants in different soil types showed that fruit vegetables and leafy vegetables in general had excellent growth in D type soil mixture and A type soil in general and had the poorest growth in E type (controlled) soil. 'Chrysanthemum zawadskii var. latilobum' had the excellent growth in D type, B type, C type mixed soil and A type soil and E type (controlled) soil are followed in order. In the case of 'Liriope platyphylla F. T. Wang & T. Tang', the difference in growth by each soil was shown to be insignificant. Therefore, the soil applied in the urban agriculture varies depending on each species of herbaceous plants, but it is considered effective to cultivate herbaceous plant which is economical and productive by using D type mixed soil which can be recycled and inexpensive compared with other experimental soils in the urban agriculture.

This study examines the process of urban formation in the city of Yanji. The analysis is done by the change of street pattern and major facility location in a timely manner by appling space syntax method. This research categorizes the pattern of the urban growth focused on two urban forms, street and major buildings, in the city and is offered of the meaning of the first value on interpretation of the urban growth in the city of Yanji. The result of the research are as follows. First, the period of the city transformation is divided into four stage; intuitive period, grid-iron formative period, consolidation period, and urban expansion period. Second, characteristics of each stage have been analyzed. At the first stage, the city started to frame along both buildings and streets which were placed without a plan. At the second stage, the city was planned and constructed into new grid-iron pattern ignoring existing context by Jananese colony. At the consolidation period, the road system expands from the city center toward suburban. At the last expansion period, the shape of the city has complicated its shape with complex road system. This study contributes to provide a basic analysis and data to investigate how the Yanji city has evolved over period of time. But further continuous research should be done for future urban development of the Yanji city.

Objectives: This study was to investigate the needs for developing the health promotion program for elderly and to compare the health promoting lifestyles behaviors and perceived health status of elderly in urban and rural area. Methods: The data was collected from 82 elders in urban(D city) and 77 elders in rural area(C county) by face to face interview. The Health Promoting Lifestyle ProfileII(HPLPII) and Perceived Health Status were used. Results: 1) The total score of HPLP was 2.44. In the subscales, the highest degree of performance was 'nutrition', following 'interpersonal relationship', 'stress management', 'health responsibility' and 'spiritual growth' and the lowest degree of performance was 'physical activity'. 2) Elderly people living in urban area had significantly higher the total HPLP score than elderly people living in rural area The urban elderly had significantly higher the score of HPLP subscales such as 'physical activity', 'interpersonal relationship' and stress management than rural elderly. 3) The mean score of perceived health status was 8.79. There was no significant difference in the perceived health status between urban and rural elderly. Conclusions: The above findings indicate that it is necessary to develop a health promotion program with reinforced physical activity, health responsibility and spiritual growth for elderly people in Korea. Especially the physical activity need to he strengthened for rural elderly.
