An ecological survey of food and nutrition was conducted in April and May, among 278 children, 6 to 12 years old, of the Youido elementary school, which offers no school lunch program, and is situated in Youido delta of Han River side of Seoul, known as the location of one of the socioeconomically high groups; Eighteen percent and 18.3% of subjects were proven to be overweight and obese, respectively. With regard to frequency of skipping breakfast, 28.4% of the subjects skipped breakfast often and 2.5% of subjects skipped breakfast every morning. Obese children showed good appetite and the time consumed for eating was shorter than those of normal or overweight children. Most serious anxiety among the mothers for those children was food habit of `eating rapidly' and `overeating'. Another striking observation was that 14.4% of the subjects ate only one side-dish with boiled rice, and such a pattern was more often found in the normal or slim group. Most of the subjects had their snacks after being back in home from school. Thirty-one percent of the children had snacks when they felt hungry, 69% had snacks for various reasons such as `habitually', `for unwinding', and `mother gives me snacks'. Thirty-eight percent of the boys and 19% of the girls had physical exercise everyday and overweight and obese children got exercise more frequently. But the time consumed for exercise was much more shorter than that of normal subjects. Most of the children liked fruits, meats, and biscuit, in contrast, lowest preferency was for vegetables, fermented fish products, and boiled rice mixed with other grains. Obese children experienced more kinds of food than normal or slim group. The study found that habits of overeating due to good appetite and eating rapidly were recognized as one of dominant reasons causing obesity among children. On the other hand, serious dietary problem of children of normal or slim group was eating less variety of food. Active nutrition education for both children and mothers will be recommended with joint participation of teachers.

To determine dining out behaviours of fast foods at five different fast food restaurants of Youido apartment compound in Seoul, a survey was conducted of 460 customers ranging in age from 7 to 29 year, from October 1 to 5th, 1986. Findings are summarized follows: The reasons the customers the fast food restaurants by the highest percentage were the following in the order: 'the atmosphere in which fast food is eaten is enjoyable for the companionship', 'convenient to dining', 'the surroundings and dining equipment are pleasant and hygienic', and 'to be able to stay as long as I want'. The majority of the customers visited the fast food restaurants with their friends between 1pm and 5pm. The fast foods purchased by the customers were mostly for snack rather than a full meal. Preference was a major factor in food selection from available meun items. Ice cream, Kentucky fried chicken, rolled rice with laver I rice cake stew, fried Mandoo were ranged high on the list of liked foods, in contrast, lower preference was for noodle soup, small red bean porridge, pinenut porridge, and persimmon punch.

In this study, we investigated the characteristics of Volatile Organic Compounds(VOCs) emission from painting and printing facilities in the Pyeongdong industrial complex in Gwangju. In addition, the objective was to understand the distribution characteristics of VOCs in the ambient air in industrial complexes affected by painting and printing facilities. The painting facility mainly emitted toluene, acetone, butyl acetate, 4-methyl-2-pentanone, ethyl acetate, 1-butanol, methyl ethyl ketone, m,p-xylene, o-xylene, 4-ethyltoluene, ethylbenzene, 3-ethyltoluene, and 1,2,4-trimethylbenzene. The main emission components in printing facilities were methyl ketone, ethyl acetate, acetone, 2-propanol, toluene, heptane, and butyl acetate. Ethyl acetate, toluene, 2-butanone, acetone, butyl acetate, 2-propanol, xylenes, and 4-methyl-2-pentanone were detected in the ambient air of the Pyeongdong industrial complex, consistent with the VOCs emitted by painting and printing facilities. The average concentration of seasonal TVOCs followed an order of winter > fall > spring > summer, whereas the concentrations of daytime and nighttime TVOCs were generally higher at night than those during the day, and the wind speed was greater during the day than it was at night. Based on a factor analysis of VOCs in the ambient air of Pyeongdong industrial complex, it is considered that organic solvents used in coating, printing, and electronics manufacturing facilities, as well as diesel vehicle emissions played a major role.

Industrial emissions, mainly from industrial complexes, are important sources of ambient Volatile Organic Compounds (VOCs). Identification of the significant VOC sources from industrial complexes has practical significance for emission reduction. VOC samples were collected from July 2019 to June 2020. A Positive Matrix Factorization (PMF) receptor model was used to evaluate the VOC sources in the area. Four sources were identified by PMF analysis, including coating-1, coating-2, printing, and vehicle exhaust. The coating-1 source was revealed to have the highest contribution (41.5%), followed by coating-2 (23.9%), printing (23.1%), and vehicle exhaust (11.6%). The source showing the highest contribution was coating emissions, originating from the northwest to southwest of the sample site. It also relates to facilities that produce auto parts. The major components of VOC emissions from the coating facilities were toluene, m,p-xylene, ethylbenzene, o-xylene, and butyl acetate. Industrial emissions should be the top priority to meet the relevant control criteria, followed by vehicular emissions. This study provides a strategy for VOC source apportionment from an industrial complex, which is helpful in the development of targeted control strategies.

Due to changes such as those stemming from the onset of the fourth industrial revolution, it is expected that industrial complexes will transform from being spacious structures into smaller, integrated complexes. Green parks, which are also a type of infrastructure within industrial complexes, also require planned direction suited to the changing environment. The planned directions of green parks in new industrial complexes were examined and surveys were conducted on industrial complex workers. Preferred functional arrangement, importance, and satisfaction levels of green ratios, preference of compound facilities linked to parks, appropriate dimensional greening methods were all surveyed across 1,035 businesses. Results of the survey exhibited that there was high awareness on the importance of building green areas, but it was found that current greenery levels were insufficient. There was a high rate of responses indicated that dimensional greening is required in building-type industrial spaces, and preferences for rooftop greenery, stair-type greenery, and atrium greenery were also high. There were many opinions that it is necessary to integrate cultural facilities, exhibition and educational facilities, commercial facilities, parking lots in parks. Furthermore, it was found that it is necessary to provide pathways for bikes and pedestrians, rather than those for vehicles, and to connect them with the green parks. This study stopped short of exploring the directions for which green parks should aim in new industrial complexes with changes in the industrial environment. In the future, more concrete plans on green park planning techniques according to the spatial characteristics and structures of new industrial complexes will be necessary.

New towns and large multi-family housing complexes are being built in the capital region of Korea, with the goal of creating safe and pedestrian-friendly cities. Traffic accidents in such residential complexes, however, is on the rise, creating social problems. While there have been many previous studies on problems with pedestrian environment; there is a dearth of studies that take design-based approach to ensure safety in pedestrian environment within residential complexes. Therefore, this study aims to prevent traffic accidents by properly planning pedestrian environment within multi-family housing complexes, in addition to emphasizing theories related to planning safer pedestrian environment in general. This study found the following design directions required to improve the design theory of pedestrian safety in multi-family housing complexes: (1) Linking traffic facilities and residential complex spaces in Korea; (2) Considering implementation of United Kingdom road systems; (3) Establishing appropriate objectives for each residential complex based on case study. In response to these findings, the study selected the A84BL complex in Hwaseong Dongtan 2 Complex located in Dongtan-myeon, Hwaseong-si in Gyeonggi Province, Korea. Items that can be implemented, as well as spatial design directions, were discussed with a focus on private vehicles, pedestrians, and service vehicles.

This study analyses the characteristics of volatile organic compounds (VOCs) emissions from the painting and printing facilities, as well as ambient VOCs at industrial complexes in Gwangju. The major components of VOCs emissions from painting facilities were toluene, acetone, 2-butanone, ethyl acetate, ethyl benzene, o-xylene and m,p-xylene. The printing facilities mostly emitted ethyl acetate, 2-butanone, acetone and toluene. Aromatics (49.9%) and oxygenated VOCs (43.6%) were dominant in painting facilities, while oxygenated VOCs (92.7%) were the largest group in printing facilities. The total hydrocarbon concentration (THC) in printing facilities was approximately six times higher than in the painting facilities. The painting and printing facilities use many solvents. Their THC concentrations differed considerably depending on the type of prevention facilities. To reduce THC, it is necessary to improve the prevention facilities and operating conditions. The dominant species of ambient VOCs in industrial complexes were investigated with toluene, ethyl acetate, 2-butanone, ethyl benzene, m,p-xylene, butyl acetate, o-xylene, hexane and acetone. Factor analysis of ambient VOCs showed that the main sources of the VOCs were organic solvents used in painting, coating, and printing, as well as automobile emissions.

In this study, the sensitivity analysis of hydraulic conductivity and separation distance (distance between injection well and pumping well) was analyzed by establishing a conceptual model considering the hydrogeologic characteristics of facility agricultural complex in Korea. In the conceptual model, natural characteristics (topography and geology, precipitation, hydraulic conductivity, etc.) and artificial characteristics (separation distance from injection well to pumping well, injection rate and pumping rate, etc.) is entered, and sensitivity analysis was performed 12 scenarios using a combination of hydraulic conductivity (10-1 cm/sec, 10-2 cm/sec, 10-3 cm/sec, 10-4 cm/sec) and separation distance (10 m, 50 m, 100 m). Groundwater drawdown at the monitoring well was increased as the hydraulic conductivity decreased and the separation distance increased. From the regression analysis of groundwater drawdown as a hydraulic conductivity at the same separation distance, it was found that the groundwater level fluctuation of artificial recharge aquifer was dominantly influenced by hydraulic conductivity. In the condition that the hydraulic conductivity of artificial recharge aquifer was 10-2 cm/sec or more, the radius of influence of groundwater level was within 20 m, but In the condition that the hydraulic conductivity is 10-3 cm/sec or less, it is confirmed that the radius of influence of groundwater increases sharply as the separation distance increases.

The study was initiated to compare seasonal nutrient variations and rice (Oryza sativa L.) productivity in each of leading rice farm with conventionally managed and recommended fertilized of the large-scale environment-friendly agricultural districts in Jangheung, Suncheon, and Okcheon provinces in 2017. Suncheon rice experimental farm plots included a recommended fertilization plot that had been additionally sown hairy vetch in the fall of previous year, while Okcheon rice farm included a recommended fertilization plot applying half amount of the compost in the conventional plot. A Jangheung rice farm only practiced crop-livestock farming system. Soil pH and EC in all experimental plots were suitable levels for rice growth to cultivate. Seasonal soil pH from March to September was the highest for Suncheon rice farm, and seasonal soil EC was the highest for Jangheung rice farm. Seasonal soil T-N increased in all the plots from March to June in particular for Suncheon rice farm, and Jangheung rice farm had the lowest seasonal soil P. Seasonal soil K decreased in all the plots, with the lowest levels observed for Okcheon farm. Seasonal soil NH4 + mostly increased by up to 90 mg/kg in Jangheung rice farm from March to June. Seasonal plant T-N, P and K concentrations were the highest for Jangheung rice farm. Seasonal plant T-N and P concentrations decreased from June to September, but K leveles were fluctuated between 2.0% and 2.5%. Seasonal SPAD value was the lowest in Suncheon conventional plot. Jangheung rice farm plot produced 6,303 kg of rice per ha, which was approximately two times higher than those of Okcheon recommended plot. The seasonal T-N, P and K balance was the highest in Okcheon conventional plot, with the lowest values observed for Suncheon conventional plot. As a result, Suncheon recommended plot showed relatively low levels of seasonal macro-nutrient balance and the highest rice production, which could be the most environmentally friendly farm practiced conducted in this study.

This study was carried out to investigate the economic value of organic rice production using gelatin ․ chitin microorganisms in eco-friendly complex, Gongsan, Naju city. The soil condition of experiment paddy field was Jeonbuk series and silt loam with a slightly poor drainage. Except for the high effective silicate, the chemical characteristics of soils used were included in the optimum range of paddy soils in Korea. In growth, plant length, tiller number, ear number, and ear length were observed to be higher in conventional paddy fields than organic paddy fields. However, number of grain per panicle and grain filling ratio (%) were higher in organic paddy fields than conventional paddy fields. Incidences of diseases and insect pests were slightly higher in the organic paddy fields. Water weevil, sheath blight, rice leaf roller and rice blast were more occurred in organic paddy field. On the other hand, false smut was higher occurred in conventional paddy field. There was a significant negative correlation between rice sheath blight and rice leaf roller, and rice yield. In the milled rice quality, the quality of organically cultivated milled rices was lower by the increase of broken rice than that of conventionally cultivated milled rices. The quality and palatability of rice were higher in organic cultivation with decreasing of protein content. Net income of conventionally and organically cultivated rice was 360,000 won/10a and 610,000 won/10a, respectively. Premium net income of the organically cultivated rice was 68%.

We examined the impact of paddy wetland's avian-diversity on the development of the protected horticulture complex. The results of this study were made to propose ecological protected horticulture complex and development direction suitable for avian habitat. The total number of species surveyed was analyzed as 1168 individuals in 11 orders 26 families and 36 generic 48 species. Type average was analyzed as paddy 17.25±4.83 species and 74.50±38.08 individuals, glass 10.00±0.82 species and 46.75±2.06 individuals, single 13.75±7.27 species and 59.50±35.34 individuals, multi 8.75±0.96 species and 36.75±9.29 individuals. Paddy showed higher species diversity than protected horticulture complex. The average number of species surveyed for one year was glass 14±2.83, multi 12±1.41, single 18±11.31, and paddy 26±11.31. The diversity difference was identified as paddy> single> glass and multi. Statistical analysis showed statistical difference of Ciconiiformes. Development of protected horticulture complex causes loss of avian habitat. The diversity index was glass 1.73±0.07, multi 1.68±0.14, single 1.91±0.47, and paddy 2.29±0.17. Paddy has a higher species diversity than the protected horticulture complex. For the purpose of ecological protected horticulture complex, detention ponds, artificial wetlands and habitats should be reflected in the design. This should be applied to reclamation areas or large-scale protected horticulture complexes.

오늘날 공동주택단지는 주거환경 수준의 향상과 주거 라이프 스타일의 변화, 이웃 간의 교류, 여가생활 증대, 건강에 대한 관심증대 등 다양한 사회문화적 현상으로 인해 변화되고 있다. 주거환경의 변화로 외부공간에 대한 필요성이 높아지고 있다. 공동주택단지 외부공간은 공동주택의 주거형태 특성상 이웃과의 교제가 부족한 환경과 단위주호 내에서 해결할 수 없는 문제점 등을 해결할 수 있으며 사회적 관계 증진과 공동체 의식 함양을 이끌 수 있는 중요한 공간이다. 이에 본 연구는 서울에 위치한 최근 완공된 공동주택단지를 대상으로 외부공간을 운동시설, 휴게시설, 놀이시설, 조경시설, 위생시설로 구 분하여 사례조사 하였으며 주민들의 커뮤니티시설로서 공간계획특성 및 디자인특성을 분석하였다. 조사결과에 따르면 운동시설의 경우 다양한 종류의 시설이 계획되어있는 반면 놀이시설이나 휴게시설은 단지별 차이가 없이 획일적인 형태로 계획되어 있어 거주자의 다양한 특성이 고려되어 있지 않았다. 특히 각 기능별 시설이 독립적으로 배치된 경우가 많아 복합적인 커뮤니티 공간으로서 거주자들의 교류를 도모할 수 있는 배치계획이 부족한 것으로 조사되어 서로 연계성 있게 계획 할 필요가 있는 것으로 나타났다. 향후 이웃과의 활발한 소통을 위한 공동주택단지 외부공간의 계획시 디자인 기초자료로 제공될 수 있을 것이다.

Agricultural or rural landscape provides various ecosystem services. However, the ecosystem services function is declining due to various environmental problems such as climate change, land use change, stream intensification, non-point pollution and garbage. The A1B scenario predicts that the mean air temperature of South Korea will rise 3.8℃ degrees celsius in 2100. Agricultural sector is very vulnerable to climate change, so it must be thoroughly predicted and managed. In Korea, the facility horticulture complex is 54,051ha in 2016 and is the 3rd largest in the world(MAFRA, 2014). Facilities of horticultural complexes are reported to cause problems such as groundwater decrease, vegetation and insects diversity reduction, landscapes damage and garbage increase, compared with the existing land use paddy fields. Heat island phenomenon associated with climate change is also accelerated by the high heat absorption of horticultural sites. Therefore, we analyzed the heat island phenomenon occurring in the facility of horticultural complex in Korea. As an improvement measurement, I examined how much air temperature is reduced by putting the channel and the open space. In the case of the Buyeo area, the Computational Fluid Dynamics (CFD) simulation was analyzed for the average summer temperature distribution in the current land use mode at 38.9℃. As an improvement measurement, CFD simulation after 10% of 6m water channel was found to have an effect of lowering the summer temperature of about 2.7℃ compared with the present average of 36.2℃. In addition, CFD simulations after analyzing 10% of the open space were analyzed at 34.7℃, which is 4.2℃ lower than the present. For the Jinju area, CFD simulations were analyzed for the average temperature of summer at 37.8℃ in the present land use pattern. As an improvement measure, CFD simulations after 10% of 6m water channel were found to have an effect of lowering the summer temperature of about 2.6℃ compared to the current average of 35.2℃. In addition, CFD simulations after analyzing 10% of the open space were analyzed at 33.9℃, which is 3.9℃ lower than the present. It can be said that the effect of summer temperature drop in open space and waterway has been proven. The results of this study are expected to be reflected in sustainable agriculture land use and used as basic data for government - level policy in land use planning for climate change.

In order to address housing issues, alleviate the concentration of urban populations, and resolve other issues regarding residential spaces, large residential complexes have been developed in Korea since the 1970s. The changes to the residential culture due to such development projects propagated rapidly, making the apartment complexes the most representative form of housing in Korea. In developing such large-scale complexes, plans for public open spaces, which play an important role in formulating the quality of residential environment, have been mostly the same, only utilizing the spaces remaining after planning other types of spaces. The current study looks at the case of Tama New Town development project, a Japanese new town development project that has a similar public open space system in large scale residential complex development projects in Korea. In doing so, the current study aims to identify the features of public open space plans. In the conclusion, the study first finds that various public open spaces must be reviewed and introduced in term of predicting social demands. Second, the study suggests the policy-makers should actively introduce pedestrian paths as a public open space. Third, the study deduces the planning implications of applying the principle of original landscape preservation.

To establish initial response scenarios for nuclear accidents around the Kori nuclear power plants, the potential for radionuclide diffusion was estimated using numerical experiments and statistical techniques. This study used the numerical model WRF (Weather Research and Forecasting) and FLEXPART (Flexible Particle dispersion model) to calculate the three-dimensional wind field and radionuclide dispersion, respectively. The wind patterns observed at Gijang, near the plants, and at meteorological sites in Busan, were reproduced and applied to estimates of seasonally averaged wind fields. The distribution of emitted radionuclides are strongly associated with characteristics of topography and synoptic wind patterns over nuclear power plants. Since the terrain around the power plants is complex, estimates of radionuclide distribution often produce unexpected results when wind data from different sites are used in statistical calculations. It is highly probable that in the summer and autumn, radionuclides move south-west, towards the downtown metropolitan area. This study has clear limitations in that it uses the seasonal wind field rather than the daily wind field.
