  • This research investigated the eating out and snack intakes situation of five hundred eighty five $5^{th}\;and\;6^{th}$ graders living in the city and rural parts of Jeonbuk province. The results of this study are as followed: Nuclear families in urban area and rural community are 84.5% and 64.7% respectively. On the other hand, extended families are 7.9% in urban area and 18% in rural communities. Out of all the households, 34.3% (urban: 37.2%, rural community: 31.5%) answered they like to eat out. Over 50.3% preferred eating Korean style food and the reason was 'the taste': urban (71.4%) and rural community (67.8%). People living in urban communities seemed to eat out more frequently than rural places and $3{\sim}4$ times a month was the average. Usually people seemed to eat out during the weekends and in the evening time 84.3% (after 7:00 p.m.). Based on each family's living standard, people answered 'we hardly ever eat out' for those in the lower class (59.1%), the middle class said once or twice a week (47.1%), and the upper class (35.7%). It was obvious that people in the middle and upper class tend to eat out more frequently than those in the lower class. The most common period of time which snacks were taken was after school (38.5%), on the way back from educational institute (35.0%) and the choices of snacks which they purchased were frozen sweets (56.4%)chips & cookies (25.2%) beverages (9.9%) Fast foods (4.6%) and fried foods (3.9%) in order. Urban children seem to eat more frozen sweets and rural children ate more chips & cookies. Also, amount of snacks between meals showed a higher percentage to those who had more pocket money, The type of snacks were fruits (37.1%) chips and cookies et cetera (19.2%) instant foods (12.8%) dairy products (11.1%) confectionary (10.3%) fried foods (5.1%) in order. The result shows that urban children eat out more frequently than those in rural areas, Eating around 7:00 p.m. was most common and the middle and upper class tend to eat out more frequently than those in the lower class, Also, snacks were most often bought before and after school. After 10:00 p.m frozen goods and chips were the most preferred choice. Specially, the reason for eating fast foods was because of the pleasing taste. From this study, it is clear that eating out and having snacks became pervasive into our lives in both urban and rural areas. Hereafter, an appropriate eating habit should be correctly educated to elementary students by spoken words and textbooks in a curriculum. In reality, snacks are classified as being the leading factor of obesity. Therefore more products containing balanced nutrition should newly develop rather than snacks with high fat content.

  • The main purpose of this research is to discuss the urban heat island which will be caused by urbanization, especially by the construction of new town on a wide green zone. Over the last ten years, five new towns have been developed around the Seoul metropolitan area. However these new towns become bedroom communities and create traffic problems between Seoul and its surrounding areas because of an increase in population and a lack of roads and other infrastructures. The construction of another such new town is under consideration in the Pan-gyo area. But it is important that Pan-gyo remains a wide green zone. Many studies show that green space can play an important role in improving urban eco-meteorological, ameliorative capability and air hygiene. The objective of this study is to analyze the urban heat islands of Bund-Dang Si which was constructed in 1996 and of the Pan-Gyo area planned as new town. To investigate the local thermal environment and its negative effects caused by change of the land use type and urbanization we used LANDSAT TM images for extraction of urban surface temperature according to change of land use over 15 years. These data were analyzed together with digital land use and topographic data. As a study result, we found that the thermal island of this area from 1985 to 1999 rapidly increased with a difference of mean temperature of more than 12'E. Before construction of Bun-Dang Si the temperature of this area was the same as the forest, but during the new town construction in 1991, an urban heat island developed. The temperature of forest with a size of over 50% of the investigation area was lowest, which leads us to conclude that the forest cools the urban and its surroundings. The mean temperature of the residential and commercial area is more than +4.5$^{\circ}C$ higher then forest, so this method of land use is the main factor increasing the urban heat island. Urban heat islands and green space play an important role in urban wind systems, i.e. Thermal Induced Air Exchange and Structural Wind Circulation, because of their special properties with regard to energy balance between constructed urban and land. The skill to allocate land use types in urban areas is a very important planning device to reduce air pollution and induce the fresh cold air from green space. An urban climatic experiment featuring a numerical wind simulation study to show the air corridor will be published in a following research paper.

  • 현재 도심 소하천의 식생조사는 주로 현장조사에 의존하여 이루어진다. UAV NIR(Unmanned Aerial Vehicle Near Infrared) 영상은 매우 낮은 고도에서 취득할 수 있어 도심 소하천과 같이 폭이 매우 좁은 표적(10m 내외)에 필요한 정보를 효율적으로 제공할 수 있다. 하지만 UAV NIR영상이 도심소하천의 식생 조사도구로서 검증되지 않아, UAV NIR 영상과 현장사진을 통합한 선행연구는 존재하지 않는다. 따라서 본 연구에서는 전통적인 원격탐사의 영역이 아니었던 국부적인 대상인 도심소하천 식생조사에서 UAV NIR 영상과 현장사진의 비교평가를 실시하였다. 하천 식생조사 결과를 실무에서 활용하는데 필요한 요구 사항을 고려하여 광역공간정보, 미시적인 정보 및 정량적인 데이터 확보 등 다양한 측면에서 분석이 수행되었다. UAV NIR 영상은 전통적인 현장조사에서 취득할 수 없었던 거시적인 주변 환경(예: 인공적인 토지 이용에 따른 영향)에 따른 식생군집패턴의 변화를 추적할 수 있었다. 현장조사는 전세계적으로 도심 소하천 식생 모니터링 방법으로 정착되었지만, 거시적인 정보의 취득에서 상당한 한계를 노출하였으며 정량적인 정보를 확보하는 과정에서도 신뢰성에 한계를 노출하였다. 본 연구가 도심 소하천의 식생조사에서 거시적이고 정량화되고 객관적인 데이터가 부재하여 직면하였던 한계를 극복할 수 있는 계기가 되어 향후 UAV NIR 원격탐사에서 확보할 수 있는 정보의 수준을 파악할 수 있는 중요한 참고자료가 될 수 있을 것으로 사료된다.

  • BACKGROUND/OBJECTIVES: This study aimed to examine the food security status of urban poor adolescents and its association with diet quality. SUBJECTS/METHODS: A cross-sectional survey was conducted among 188 adolescents aged 13-18 yrs living in Kuala Lumpur, Malaysia. Household food insecurity and dietary intake data were collected using the Radimer/Cornell hunger and food insecurity instrument and 2-day 24-h dietary recalls, respectively. Diet quality was determined using the Malaysian Healthy Eating Index (HEI). Weight and height were measured and body mass index-for-age, as well as height-for-age z scores were calculated. RESULTS: The present study revealed that 47.9% of the adolescents experienced household food insecurity, 24.5% experienced individual food insecurity, 18.6% household food security, and 9.0% child hunger. The mean score of diet quality was 56.83 ± 10.09, with a significantly lower HEI score among food insecure adolescents (household food insecure, individual food insecure, and child hunger) than household food secure adolescents (P = 0.001). The differences between food secure and food insecure households were found to be significant for energy (P = 0.001) and nutrients including proteins (P = 0.006), carbohydrates (P = 0.005), dietary fiber (P = 0.001), folate (P < 0.001), and vitamin C (P = 0.006). The multiple linear regression showed that adolescents who experienced food insecurity (β = -0.328; P = 0.003) were found to be significantly associated with poor diet quality (F = 2.726; P < 0.01), wherein 13.3% of the variation in the diet quality was explained by the food security status. CONCLUSIONS: Experiencing food insecurity contributed to poor diet quality among urban poor adolescents. Further longitudinal studies are needed to comprehensively understand this association to improve food insecurity and diet quality among urban poor communities.

  • 그린인프라는 지속가능한 커뮤니티를 조성하는 데에 주요한 전략으로 고려되고 있다. 하지만 도시 레질리언스와 시스템의 역동성이라는 관점에서 그린인프라에 관한 연구는 아직 부족하며 이를 어떻게 물리적인 적용과 융합하는가에 관한 연구 역시 미미하다. 본 연구는 두 가지의 원인에 주목한다. 첫째는 정적변수를 고려하는 기존의 그린인프라 계획과 동적변수를 고려하는 도시모델링 연구 사이의 간극이며, 둘째는 도시모델링 연구와 조경설계 간의 정보 및 방법의 차이이다. 본 연구는 도시성장에 따른 그린인프라의 수요의 분포를 전망하며 설계의사결정을 지원하는 융합모델링을 제안한다. LEAM모델과 MCDA모델을 융합하여 그린인프라의 서비스와 사회경제적 도시변화의 관계성을 평가하고, 2050년의 그린인프라의 수요를 공간적으로 전망한다. 모델의 결과는 시카고 외곽에서의 도시화가 진행될수록 생태시스템 서비스의 질적 저하가 일어날 가능성이 있음을 말한다. 이는 경제성장에 의해 그린인프라에 대한 수요가 지리적으로 변화할 수 있음을 나타내며, 그린인프라 전략이 현재와 미래를 유동적이자 포괄적으로 고려해야 함을 제안한다. 나아가 본 연구는 스튜디오 환경에서의 생산된 정보를 학생들과 공유하여 근거기반 설계의 적용과 가능성에 관해 논의한다. 지오디자인의 관점에서 그린인프라 설계 및 계획과 도시시스템 연구의 융합을 통해 효율적인 설계의사결정을 지원함으로써 보다 탄력적인 도시환경을 조성하는데 기여하고자 한다.

  • The categories of national health problems may be mainly divided into health promotion, problems of diseases, and population-economic problems which are indirectly related to health. Of them, the problems of diseases will be exclusively dealt with this speech. Rurality and Disease Problems There are many differences between rural and urban areas. In general, indicators of rurality are small size of towns, dispersion of the population, remoteness from urban centers, inadequacy of public transportation, poor communication, inadequate sanitation, poor housing, poverty, little education lack of health personnels and facilities, and in-accessibility to health services. The influence of such conditions creates, directly or indirectly, many problems of diseases in the rural areas. Those art the occurrence of preventable diseases, deterioration and prolongation of illness due to loss of chance to get early treatment, decreased or prolonged labour force loss, unnecessary death, doubling of medical cost, and economic loss. Some Considerations of Innovative Approach The followings art some considerations of innovative approaches to the problems of diseases in the rural Korea. 1. It would be essential goal of the innovative approaches that the damage and economic loss due to diseases will be maintained to minimum level by minimizing the absolute amount of the diseases, and by moderating the fee for medical cares. The goal of the minimization of the disease amount may be achieved by preventive services and early treatment, and the goal of moderating the medical fee may be achieved by lowering the prime cost and by adjusting the medical fees to reasonable level. 2. Community health service or community medicine will be adopted as a innovative means to disease problems. In this case, a community is defined as an unit area where supply and utilization of primary service activities can be accomplished within a day. The essential nature o the community health service should be such activities as health promotion, preventive measures, medical care, and rehabilitation performing efficiently through the organized efforts of the residents in a community. Each service activity should cover all members of the residents in a community in its plan and performance. The cooperation of the community peoples in one of the essential elements for success of the service program, The motivations of their cooperative mood may be activated through several ways: when the participation of the residents in service program of especially the direct participation of organized cooperation of the area leaders art achieved through a means of health education: when the residents get actual experience of having received the benefit of good quality services; and when the health personnels being armed with an idealism that they art working in the areas to help health problems of the residents, maintain good human relationships with them. For the success of a community health service program, a personnel who is in charge of leadership and has an able, a sincere and a steady characters seems to be required in a community. The government should lead and support the community health service programs of the nation under the basis of results appeared in the demonstrative programs so as to be carried out the programs efficiently. Moss of the health problems may be treated properly in the community levels through suitable community health service programs but there might be some problems which art beyond their abilities to be dealt with. To solve such problems each community health service program should be under the referral systems which are connected with health centers, hospitals, and so forth. 3. An approach should be intensively groped to have a physician in each community. The shortage of physicians in rural areas is world-wide problem and so is the Korean situation. In the past the government has initiated a system of area-limited physician, coercion, and a small scale of scholarship program with unsatisfactory results. But there might be ways of achieving the goal by intervice, broadened, and continuous approaches. There will be several ways of approach to motivate the physicians to be settled in a rural community. They are, for examples, to expos the students to the community health service programs during training, to be run community health service programs by every health or medical schools and other main medical facilities, communication activities and advertisement, desire of community peoples to invite a physician, scholarship program, payment of satisfactory level, fulfilment of military obligation in case of a future draft, economic growth and development of rural communities, sufficiency of health and medical facilities, provision of proper medical care system, coercion, and so forth. And, hopefully, more useful reference data on the motivations may be available when a survey be conducted to the physicians who are presently engaging in the rural community levels. 4. In communities where the availability of a physician is difficult, a trial to use physician extenders, under certain conditions, may be considered. The reason is that it would be beneficial for the health of the residents to give them the remedies of primary medical care through the extenders rather than to leave their medical problems out of management. The followings are the conditions to be considered when the physician extenders are used: their positions will be prescribed as a temporary one instead of permanent one so as to allow easy replacement of the position with a physician applicant; the extender will be under periodic direction and supervision of a physician, and also referral channel will be provided: legal constraints will be placed upon the extenders primary care practice, and the physician extenders will used only under the public medical care system. 5. For the balanced health care delivery, a greater investment to the rural areas is needed to compensate weak points of a rurality. The characteristics of a rurality has been already mentioned. The objective of balanced service for rural communities to level up that of urban areas will be hard to achieve without greater efforts and supports. For example, rural communities need mobile powers more than urban areas, communication network is extremely necessary at health delivery facilities in rural areas as well as the need of urban areas, health and medical facilities in rural areas should be provided more substantially than those of urban areas to minimize, in a sense, the amount of patient consultation and request of laboratory specimens through referral system of which procedures are more troublesome in rural areas, and more intensive control measures against communicable diseases are needed in rural areas where greater numbers of cases are occurred under the poor sanitary conditions.

  • 본 연구는 대구시의 도시숲과 가로경관(수림대, 가로수, 녹지대)의 조류군집을 비교하고자 실시하였다. 관찰된 31종의 조류 중 까치, 박새는 모든 지역에서 나타났으나, 딱새, 할미새사촌, 파랑새, 노랑턱멧새, 숲새 등 5종은 한번만 관찰되어 낮은 출현빈도를 보였다. 시 외곽부에 위치한 도시숲(만촌, 본리, 침산공원)에서 조류 종수가 높았으나 도심의 도시숲(중리, 이곡생수, 신암공원)에서 조류 종수는 낮았다. 가로경관에서 관찰된 조류의 번식 둥지는 수림대와 녹지대에서는 발견되었으나, 한 줄 가로수에서는 발견되지 않았다. 수림대지역에서 관찰된 조류의 종수와 밀도는 한 줄 가로수지역보다 유의하게 높았다. 도시숲 면적과 조류종수는 높은 상관관계를 나타냈다. 덤불층을 둥지 및 먹이자원으로 이용하는 조류 종수가 낮았으며, 면적이 증가함에 따라 증가율도 낮았다. 본 연구 결과는 대구시 도시숲은 덤불층을 서식지로 이용하는 조류에게 충분한 서식 여건을 제공하지 않는 것을 나타내며, 조류는 수림대와 녹지대 등 폭이 있는 가로경관을 서식지 및 이동통로로 이용함을 나타낸다.
