This study analyzed the cold air characteristics of the Nakdong Jeongmaek, which is advantageous for the formation of cold air that can flow into the city, in order to suggest the wind ventilation corridor plans, which have recently been increasing interest as a way to improve the urban thermal environment. In addition, based on the watershed analysis, specific cold-air watershed areas were established and management plans were suggested to expand the cold air function of the Nakdong Jeongmaek. As a result of the analysis of cold air in the Nakdong Jeongaek, cold air was strongly generated in the northern forest of the Jeongamek, and flowed into nearby cities along the valley topography. On average, the speed of cold air was high in cities located to the east of the Jeongmaek, while the height of cold air layer was high in cities located to the west. By synthesizing these cold air characteristics and watershed analysis results, the cold-air watershed area was classified into 8 zones, And the plans were proposed to preserve and strengthen the temperature reduction of the Jeongmaek by designating the zones as 'Conservation area of Cold-air', 'Management area of Cold-air', and 'Intensive management area of Cold-air'. In addition, in order to verify the temperature reduction of cold air, the effect of night temperature reduction effect was compared with the cold air analysis using weather observation data. As a result, the temperature reduction of cold air was confirmed because the night temperature reduction was large at the observation station with strong cold air characteristics. This study is expected to be used as basic data in establishing a systematic preservation and management plan to expand the cold air function of the Nakdong Jeongmaek.

First, The spatial distribution characteristics of old big trees were analyzed using ArcGIS figures by combining basic information such as species and ages of old big trees in Handan City, which were compiled by the local bureau of landscaping. The types of species, distribution by ages of trees, ownership status, growth status, and diversity status were comprehensively analyzed. Statistically, Styphnolobium, Acacia, Gleditsia, and Albizia of Fabaceae accounted for the majority, of which Sophora japonica accounted for the highest proportion. Sophora japonica is widely and intensively distributed to each prefecture and district in Handan city. According to the age and distribution, the old big trees over 1000 years old were mainly Sophora japonica, Zelkova serrata, Juniperus chinensis, Morus australis Koidz., Dalbergia hupeana Hance, Ceratonia siliqua L., and Pistacia chinensis, and Platycladus orientalis. Second, as found in each type of old big tree status, various types of old big tree status were investigated, the protection management system, protection management process, and protection management benefits were studied, and the protection of old big tree was closely related to the growth environment. Currently, the main driving force behind the protection of old big trees is the worship of old big trees. By depositing its sacredness to the old big tree and sublimating the natural character that nature gave to the old big tree into a guiding consciousness of social activities, nature's "beauty" and personality's "goodness" are well combined. The protection state of the old big tree is closely related to the degree of interaction with the surrounding environment and the participation of various cultures and subjects. In the process of continuously interacting with the surrounding environment during the long-term growth of old big trees, it seems that a natural sanctuary was formed around old big trees in the process of voluntarily establishing a "natural-cultural-scape" system involving bottom-up and top-down cross-regions, multicultural and multi-subjects. Third, China focused on protecting and recovering old big trees, but the protection management system is poor due to a lack of comprehensive consideration of historical and cultural values, plant diversity significance, and social values of old big trees in the management process. Three indicators of space's regional characteristics, property and protection characteristics, and value characteristics can be found in the evaluation of the natural characteristics of old giant trees, which are highly valuable in terms of traditional consciousness management, resource protection practice, faith system construction, and realization of life community values. A systematic management system should be supported as to whether they can be protected and developed for a long time. Fourth, as the perception of protected areas is not yet mature in China, "natural sanctuary" should be treated as an important research content in the process of establishing a nature reserve system. The form of natural sanctuary management, which focuses on bottom-up community participation, is a strong supplement to the current type of top-down nature reserve management in China. Based on this, the protection of old giant trees should be included in the form of a nature reserve called a natural monument in the nature reserve system. In addition, residents of the area around the nature reserve should be one of the main agents of biodiversity conservation.

This paper develops the argument that the 'Healthy Cities Approach' extends beyond the boundaries of officially designated Healthy Cities and suggests that signs of it are evident much more widely in efforts to promote health in the United Kingdom and in national policy. It draws on examples from Leeds, a major city in the north of England. In particular, it suggests that efforts to improve population health need to focus on the wider determinants and that this requires a collaborative response involving a range of different sectors and the participation of the community. Inequality is recognised as a major issue and the need to identify areas of deprivation and direct resources towards these is emphasised. Childhood poverty is referred to and the importance of breaking cycles of deprivation. The role of the school is seen as important in contributing to health generally and the compatibility between Healthy Cities and Health Promoting Schools is noted. Not only can Health Promoting Schools improve the health of young people themselves they can also develop the skills, awareness and motivation to improve the health of the community. Using child pedestrian injury as an example, the paper argues that problems and their cause should not be conceived narrowly. The Healthy Cities movement has taught us that the response, if it is to be effective, should focus on the wider determinants and be adapted to local circumstances. Instead of simply attempting to change behaviour through traditional health education we need to ensure that the environment is healthy in itself and supports healthy behaviour. To achieve this we need to develop awareness, skills and motivation among policy makers, professionals and the community. The 'New Health' education is proposed as a term to distinguish the type of health education which addresses these issues from more traditional forms.

This research is to the establishment of a conceptual framework that supports road characteristic classification from a new point of view in order to complement of the existing road functional classification and examine of traffic pattern. The road characteristic classification(RCC) is expected to use important performance criteria that produced a policy guidelines for transportation planning and operational management. For this study, the traffic data used the permanent traffic counters(PTCs) located within the national highway between 2002 and 2006. The research has described for a systematic review and assessment of how exploratory factor analysis should be applied from 12 explanatory variables. The optimal number of components and clusters are determined by interpretation of the factor analysis results. As a result, the scenario including all 12 explanatory variables is better than other scenarios. The four components is produced the optimal number of factors. This research made contributions to the understanding of the exploratory factor analysis for the road characteristic classification, further applying the objective input data for various analysis method, such as cluster analysis, regression analysis and discriminant analysis.

Recently, urban information system(UIS) has been developed and utilized by local governments in Korea and has become a key means of urban informatization of local governments. When UIS is conducted only for FM oriented internal utilization regardless of its cost-efficiency, however, its cost-benefit structure could be distorted seriously. The study utilizes benefit cost analysis technique and applied the technique to a model case of Chungju UIS selected by National GIS team. Chungju City developed its GIS for the management of roads and urban planning in 1993. At its beginning, the system was an efficient model with relatively strong cost-benefit structure and could produce positive net benefit 10 years' after its construction. When the city began to develop its facility management with the financial assistance from central government in 1998, however, its cost-benefit structure became distorted. As a result, it is delayed for the UIS to produce positive net benefit until the year of 2015. Using benefit cost ratio, discount rate and Mobile GIS, the study also conducts a sensitivity analysis.

Building Construction projects are getting higher and larger. Therefore, the use of Tower Crane, which is more productive than any other lifting plan shows a trend of continuous increases. However as equipment for transporting heavy goods, are is too expensive for the monthly rent and used inefficiently for construction. site so it is analyzed that it has problems of reducing productivity and efficiency of lifting work. Inefficient situations are arising like poor communications between operator and worker, occurrence of blind spots, securing the shortest distance of fire during movement after lifting plan, influences of weather, location of materials, movement radius of tower crane by each locations and ever-changing working environments. Therefore, in this study, we first made a list of tower cranes that are inefficiently used at the site, and then we made a checklist. After that, through field visits, we derived checklist for Tower Crane to comprehensive data value.

How to make use of the surplus labor force is the key problem referring to success or failure of new rural building in China. The purpose of the paper is to know exactly that what the problems to the development in the rural area, especially the problem of the rural labor force. The way to solve rural labor force question is to protect the rights of peasants, eliminate the extant city and rural's partitioning pattern and give them the same treatment. Firstly, it should dominate the city and rural economic society's development; Secondly, it should dominate the markets in city and rural, and speed up the fair competition in employment; Thirdly, it should dominate the infrastructural facilities in city and rural; Fourthly, it should dominate the education and social enterprises in city and rural; Fifthly, it should dominate the social security system in city and rural. It should also enlarge the investment of funding, science technology, talented person and management. This is the only way to solve the problem of rural labor force outlet.

In primary and secondary schools, various information, such as grade results, observation and counseling materials, and psychological examination results which are generated in the course of educational activities, are accumulated and managed in various forms. Nevertheless, there is no educational information system that provides the analytical information for diagnosing and grasping students in a multidimensional manner. This is reminiscent of situations in which doctors rely solely on clinical experience to treat patients without using the results of various tests on patients. As pointed out by the Ministry of Education in 'Educational Big Data Utilization Measures' of the 5th Basic Plan of Educational Informatization(2014 ~ 2018), the reason why educational information systems do not exist is because there are no basic research as well as comprehensive and systemic research on this field. Therefore, this study aims to design and implement a prototype for educational information system that enables customized student guidance by introducing the concept of analytical information systems that are used in various fields. We defined the core functions and contents of educational information system through job analysis and focus group interview, and implemented the prototype using Naver ProtoNow.

K-WEAP(Korea-Water Evaluation And Planning System)은 유역의 물이용 순환체계를 컴퓨터 프로그램으로 구현하고, 수량, 수질, 환경, 수요관리 등을 종합적으로 고려하여 통합수자원계획 수립을 지원하는 전문 모형으로서, 과학기술부와 건설교통부가 공동으로 지원하는 21세기 프론티어 사업인 수자원의 지속적 확보기술사업단의 연구비 지원에 의하여 SEI-B(Stockholm Environment Institute-Boston Center)와 한국건설기술연구원이 공동으로 개발한 모형이다. K-WEAP의 대부분 기능은 기존의 SEI-B가 개발한 WEAP(Water Evaluation And Planning System)에 기반을 두고 있지만, 월 단위 물수지 분석뿐만 아니라 5일 및 임의 시간 단위 물수지분석이 가능하고 물공급 안전도평가와 하천수질모의가 가능하다는 점에서 기존의 WEAP과는 다르며 메뉴와 도움말이 모두 한글로 작성되어있어 국내 사용자들이 이용하기 용이하다. K-WEAP의 기능은 단계적으로 보완 및 개선이 이루어지고 있으며, 현재는 1단계 개발이 끝난 후 2단계 기능개선 작업을 수행하고 있다. 2단계에서 개선하게 될 주요부분은 물수지모형의 개선과 하천수질모형의 개선, 편익산정모형의 개발, 의사결정지원 기능을 고려하는 사용자인터페이스 개선 등이 포함되어 있으며, 2단계 1차 년도에서는 물수지모형과 하천수질모형의 부분적인 개선과 함께 의사결정지원 기능을 고려하는 사용자 인터페이스의 부분적인 개선을 시도하였다. 물수지모형의 개선에서는 하수처리장의 회귀수를 수요처에서 직접 이용할 수 있도록 하였으며, 하천수질모형의 개선부분에서는 기온과 풍속 등의 기후자료를 이용한 수온 모의모형을 개발하였다. 또한, 사용자 인터페이스 부분에서는 사용자의 의사결정을 지원하기 위해 하천유량과 수질 등에 대한 초과비율그래프 조회 기능과 결과를 지도상에서 확인할 수 있는 지도보기기능, 사용자가 필요한 자료를 요약하여 조회할 수 있는 사용자 정의보고서 작성기능을 추가하였다. 개선된 기능을 통해 사용자는 보다 편리한 환경에서 모형을 구동하고 구동결과를 평가 할 수 있을 것으로 기대된다.
