This study focuses on the economies of launching regular air services between capital cities of South Korea and North Korea. The demand for traveling between these two cities is too small to justify scheduled air service. However, it may be possible to provide regular air service by utilizing via flight of incumbent Seoul-Beijing flights. There are numerous flight services between Seoul and Beijing and we may allow some of the Seoul-Beijing flights to stop by Pyung Yang for commercial traffic handling. This study tries to find the optimal discount rate which passengers traveling between Seoul and Beijing via Pyung Yang, the idea is reasonable considering the inconvenience of stopping at Pyung Yang. The Stated Preference Techniques are applied for the study. The required data were collected through interviews of passengers traveling from Seoul to Beijing. The major variables that are considered in flight choice are air fare, flying time, and flight frequency. The relative importance of these major variables is estimated by the logit models calibrated with stated preference data.

Korea has designated 28 trade ports and 22 coastal ports under the Ports Act. If fishery ports and small inlets are counted, the number amounts to hundreds of ports. However, untimely and inefficient maintenance and repair works face Korean ports with functional loss, decreasing efficiency, and even catastrophe. Thus, further examinations on the maintenance or redevelopment of forts in Korea are urgent. Since the Korean War and the higher economic growth period in the 1970s, Busan Port has developed in a variety of ways, according to the necessity of social conditions at any given time, without any development Philosophy or systematic long-term master plan. As a result, ports and coastal industrial facilities have rushed to gather around the present North Busan Port, which has taken on mixed functions between ports and cities, adversely affecting several of their interactions. To resolve these circumstances, several redevelopment schemes were suggested for centering the old zone in the Busan Port interim. However, comprehensive evaluation and redevelopment schemes combining functions of both ports and cities, and effectively utilizing coastal zones have never been presented. In this respect, this study sets the priority order of the extracted unit project. This study analyzes the existing functions and facilities of Busan Port, extracting facility zones through redevelopment which is certain to fail or to decrease in efficiency. furthermore, this study presents status and development directions of specified redevelopment unit projects of higher priority order, and pursues the integrated plan of efficiency for Busan Port.

This result showed that the middle school students' response for the environment condition was highly negative. The major findings of this study are as follows. 1. Students would become to know the environmental pollution through reading of newspapers and TV rather than school education. 2. Students' response for air and water pollution was seriously accepted in city areas than in country areas, and in large cities than in small cities. 3. Students' response for air pollution showed that the quality of air was getting worse and major factor of air pollution was the exhausts of automobiles. 4. It showed that students' concern for water pollution was increased and water pollution was being accelerated by the increase of domestic and industrial sewages, the overuse of the agricultural chemicals, the entrophication and acid rain. 5. Students thought that soil pollution was mainly due to factory sewage, life sewage, heavy metal and agricultural medicines and so on. But now they think it is due to the degenerated and inseparable things such as used vinyle for farm and plastics. 6. Most students thought of the pollution of our country as serious. But they thought it could be removed if we tried to get rid of pollution. 7. Now students' consciousness to protect the nature took an active interest turn and was strong. Putting these various findings together, I suggested that, the efforts to turn students affirmative consciousness for the environment and a powerful plan by the nation to take off pollution should be needed. Also the education to enforce the environment preservation had to be needed.

This study investigated the needs to improve the quality of foodservice management in community child centers (CCCs), in accordance to the area where the CCC was located. The people in charge of foodservice management of 466 community child centers undertook a web survey, between July to August 2016. Most centers used menus from the Headquarters of Community Child Center (50.0%) or Center for Children's Foodservice Management (34.1%). Factor analysis and multiple regression analysis were conducted to assess the requirement for improving the quality of foodservice management at the CCCs. Four factors were analyzed: 'food material and facility management', 'administration management', 'menu management', and 'human resources management'. In large cities, 'administration management' and 'menu management' were found to affect quality improvement. In small cities, none of the factors assessed were effective in improvement. 'human resources management' had a significant influence on improving the quality of the foodservice in rural areas. The results of this study show that there was a difference in the quality improvement of the foodservice management in the centers, with respect to the location of the center. Therefore, this study can be used as basic data to establish the support policy for improving the quality of foodservice management in community child centers.

Recently, an increasing number of urban farmers are growing fresh vegetables and fruits themselves using urban garden or weekend farms. In other words, this is called urban agriculture. After the Industrial Revolution in the 18th century, the agricultural society changed from an agricultural society to an industrial society, and the population began to flock to the cities. With the continued increase of urban population, countries with abundant capital were able to control the distribution structure of food supplies and trade agreements among countries. Since energy consumption and carbon dioxide emissions caused by agricultural product movements have emerged as the main culprits of global warming, and our table is threatened by safety due to food supply that has no genetic modification or knowledge of the cultivation process, urban agriculture is already taking hold in the West. In other words, as agriculture met cities, its role grew. Each region actively conducts agricultural activities for raising poultry as well as growing vegetables and fruits by using flower beds of detached houses in the city center, rooftops of high and low buildings, or school playgrounds and small tributaries of land. The purpose of this study is to analyze and understand the significance and type of urban agriculture and to examine the cases of domestic and foreign urban agriculture based on this and to seek the developing direction of urban agriculture, which is gradually increasing. Tired of growing competition and rapid change, urbanites are seeking health and relaxation and are planning to present development measures for urban farming and conduct follow-up research to ensure safe food.

Recently, the demand for more precise and demand-oriented customized spatial information is increasing due to the 4th industrial revolution. In particular, the use of 3D spatial information and digital twins which based on spatial information, and research for solving social problems in cities by using such information are continuously conducted. Globally, non-face-to-face services are increasing due to COVID-19, and the national policy direction is also rapidly progressing digital transformation, digitization and virtualization of the Korean version of the New Deal, which means that 3D spatial information has become an important factor to support it. In this study, physical objects for cities defined by world organizations such as ISO, OGC, and ITU were selected and the target of the 3D object model was limited to buildings. Based on CityGML2.0, the data collected using a drone suitable for building a 3D model of a small area is selected to be updated through road name address and building ledger, which are administrative information related to this, and LoD2.5 data is constructed and urban space. It was intended to suggest an object update method for a 3D building among data.

In this study, water resource topics, infrastructure, water supply, users, and economic indicators based on statistical annual standards for evaluating water welfare were selected by examining domestic and foreign water resource-related indicators. The level of water welfare was evaluated relative to 23 cities and counties in Daegu and Gyeongsangbuk-do using data from the Statistical yearbook, and places with high value of indicators urbanization and large populations were excellent in the infrastructure field, but overall analysis showed that small and medium-sized cities had higher levels. It is judged that it is necessary to develop continuous research and indicators that can evaluate and quantify the level of physical welfare that the people can feel by utilizing the results of this study. In future studies, it is necessary to systematically evaluate the level of water welfare by local governments in Korea through more diverse evaluation items and detailed indicators for each item so that it can be used as basic data for realizing water welfare.

Due to the standardized urban development since the industrial era, many urban spaces have experienced non-placeness. Recently, although interest in urban landscape, history, and cultural elements has been increasing, landscape management and control measures are being implemented mainly in large cities due to the low status of rural areas in the country. From this point of view, this study tried to lay the foundation for basic research in related fields by classifying the characteristics and types of streetscapes located near large cities, and to suggest directions that should be considered when managing streetscapes in the future. As a result of the analysis of landscape adjectives, the village felt secluded due to the low density compared to the city street overall, but it did not have a unique image of the region. Three factors were derived through factor analysis, and preference was affected in the order of aesthetic, regularity, and uniqueness. In addition, the research site was classified into three types through cluster analysis, and it was confirmed that the differences by type were due to aesthetics and naturalness. On the other hand, the uniqueness is generally low in all regions, so it seems that fundamental countermeasures are needed.

Many houses have been left vacant in cities worldwide due to changes in the economy, society, and urban composition. The increase in vacant houses causes social problems and decrease in the value of real estate. Considering the cost of preparing a new residence because the existing residence no longer functions, it is an important problem to solve empty houses in the existing residence. Accordingly, policy attempts and studies to reduce and utilize vacant houses are in progress in various countries. In South Korea, the ratio of vacant houses was 6.4% of all houses as of 2021, and in Jeolla-buk-do, it was 11.6%, which is higher than the national average. Jeollabuk-do conducted a fact-finding survey on countermeasures against vacant houses; 17,732 vacant houses (2.4%) were surveyed. The urbanization, population, and terrain of Jeollabuk-do, consisting of 14 cities and counties, were considered. The ratios, types, grades, and spatial autocorrelations of vacant houses were analyzed after classification into city areas (focus, small, and medium) and county areas (plains and mountains) areas to derive policies according to the distribution of vacant houses. The average difference in ratio, type, grade, and spatial autocorrelation of vacant houses was used to analyze the characteristics of the distribution of vacant houses according to these classifications. There were significant differences in the averages of the ratios, grades, and spatial autocorrelations between city and county areas. The autocorrelation of vacant house distribution exhibited differences between urban and county areas.

도시기후와 같은 소기후를 연구하기 위하여는 도시는 물론 그 주변의 농촌지역에 이르기까지 조밀한 기상관측망이 필요하다. 그러나 한국에서 뿐만 아니라 선진제국에서도 기상관측망의 밀도가 도시기후를 파악하기에 충분할 만큼 조밀하지 못한 실정에 있다. 이러한 상항하에서 도시기후에 관하여 연구하려면 기초자료부터 측정하여야하는 어려움이 있으며, 따라서 그 연구의 필요성은 절감하면서도 실제적인 연구는 극히 부진하여 그 범위도 대단히 한정되어 있다. 1960년에 TIROS 1호가 미국에서 발사된 이래 다수의 기상위성이 궤도상에서 선회하며 많은 기상정보를 지상으로 보내주고 있다. 그리하여 현장관측이 어려운 각종 기상현상에 관한 정보를 짧은 시간안에, 그리고 경우에 따라서는 적은 비용으로 입수할 수 있게 됨으로써 기상연구에 박차가 가하여지게 되었다. 특히 최근에는 컴퓨터 프로그램의 발달과 더불어 해상력이 1km인 AVHRR의 영상을 대축척으로 확대하여 사용할 수 있게 되는 한편 여러가지 오류도 수정할 수 있게 되었다. 그리고 이들 위성으로부터 관측된 열적외선 영상은 도시열섬을 나타내는데 있어서 중용한 자료로 사용할 수 있게 되었다. 본 연구에서는 원격탐사 기법에 의한 도시열섬 연구의 가능성을 타진하여 보고자 NOAA AVHRR 영상을 이용하여 남한지역의 도시열섬의 존재와 수도권지역 열섬의 강도 및 형태를 알아보고 나아가 도시열섬과 여러 도시현상간의 관계를 밝혀 보고자 한다.
