언제 더웠냐 싶게 꽤나 썰렁한 바람이 부는 날이다. 추수를 하고 있는 농부의 모습이 차창을 스치고 지나간다. 수건을 쓴 어느 아주머니가 허리를 펴고 하늘을 한번 쳐다본다. 무슨 재미있는 얘기를 주고받았을까. 커다란 웃음소리가 크게 들렸다가 서서히 사라져간다. 기자는 건강검진차를 찾아, 자궁암검사를 받았다가 병을 조기발견하고 두 달에 걸친 치료 끝에 건강을 되찾아 행복한 생활을 하고 있는 정부영씨(경기도 수원시 세곡2동 537-19)를 만나러 갔다. 자신이 당한 일을, 슬퍼하기 보다는 좋은 경험이라고 얘기하는 그녀를 만나면서, 기자는 많은 것을 생각하고 배울 수 있었다.

Providing high-quality meteorological observation data at sites that represent actual farming environments is essential for useful agrometeorological services. The Automated Agricultural Observing System (AAOS) of the Korean Meteorological Administration, however, has been deployed on lawns rather than actual farm land. In this study, we show the inaccuracies that arise in AAOS data by analyzing temporal and vertical variation and by comparing them with data recorded by the National Center for AgroMeteorology (NCAM) tower that is located at an actual farming site near the AAOS tower. The analyzed data were gathered in August and October (before and after harvest time, respectively). Observed air temperature and water vapor pressure were lower at AAOS than at NCAM tower before and after harvest time. Observed reflected shortwave radiation tended to be higher at AAOS than at NCAM tower. Soil variables showed bigger differences than meteorological observation variables. In August, observed soil temperature was lower at NCAM tower than at AAOS with smaller diurnal changes due to irrigation. The soil moisture observed at NCAM tower continuously maintained its saturation state, while the one at AAOS showed a decreasing trend, following an increase after rainfall. The trend changed in October. Observed soil temperature at NCAM showed similar daily means with higher diurnal changes than at AAOS. The soil moisture observed at NCAM was continuously higher, but both AAOS and NCAM showed similar trends. The above results indicate that the data gathered at the AAOS are inaccurate, and that ground surface cover and farming activities evoke considerable differences within the respective meteorological and soil environments. We propose to shift the equipment from lawn areas to actual farming sites such as rice paddies, farms and orchards, so that the gathered data are representative of the actual agrometeorological observations.

예부터 농민은 가진 것이 땅밖에 없다고 얘기되어져 왔다. 도시의 사시사철 흥청거림과는 무관한 듯 가을 추수가 끝나야 비로소 돈을 만져보게 되는 농민들. 그들의 얼굴엔 부유함이나 깔끔한 보다는 부지런함과, 흙과 함께 살아온 텁텁함이 강하게 배어있다. 그러나 그들 역시 발달되는 문명 속에서 현대인이면 누구나 직면하게 되는 질병과 재해를, 그 흥청거림을 외면하듯 등져버릴 수는 없다. 그러나 그들에겐 그 위험으로부터 자신을 보호하기 위해 무엇을 준비한다는 것이 사실상 어렵다. 농협중앙회의 공제사업은 이런 처지의 농민을 위해 시작되었다고 볼 수 있다. 농협공제사업은 그 동안 다양한 복지환원사업을 실시해, 이제는 대다수의 농민에게 많은 호응을 받고 있다. 그것은 지난 ‘86년부터 실시되어온 무료건강검사의 과정 속에서 농민의 입을 통해 입증되어지고 있다. ’1인은 만인을 위해, 만인은 1인을 위해‘라는 모토아래 실시되고 있는 농협공제사업이 왜 농민으로부터 좋은 반응을 얻고 있는지, 농민이 진정으로 원하는 것이 무엇인지를 알아보기로 한다.

The purpose of this review is to discuss the debate concerning the interpretation of epidemiologic studies on particles and health effects. Study of the 1952 air pollution disaster in London established that very high levels of particulate-based smog can cause dramatic increases in daily mortality. However, recent epidemiologic studies have reported statistically significant health effects and mortality due to low levels of air pollution. The statistical significance does not prove causation in observational studies; therefore it is necessary to evaluate these associations. There are arguments for and against each of the numerous studies using Hill's criteria, however the body of accepted evidence supports the causal association. In particular, a high level of consistency in the estimated effect of PM10 has been observed across studies worldwide. The mechanism of the relationship between air pollution and health effects is not obvious. The mechanism of particle-induced injury may involve the production of an inflammatory response by the particulate. The harvesting and the threshold effect are also major concerns regarding the health effects of air pollution. However, current epidemiologic findings indicate that linear models lacking a threshold are appropriate for assessing the effect of particulate air pollution on daily mortality even at current levels.

This study aims to explore the duty system of the lifelong learning counseling, and to analyze the needs of counseling practice which are conceived by lifelong education practitioners. Based on the related prior studies, the duty system of lifelong learning counseling was investigated and classified. Also, differences of how to recognize the importance of counseling job and how to practice counseling are assessed by Borich method. After data were collected by practitioners from lifelong education field, the dependent t-test and the Borich needs assessment formula were used for analysis of the collected data. The results are as follows: the 4 subdivided duties of lifelong learning counseling are formation of relationship, learner's analysis, learning promotion, and follow-up management. The 11 tasks are learner's interview, providing learning information, analysis of learner's characteristics and needs, learning level diagnosis, diagnosis of learning inhibiting factors, promotion of learning motivation, advice of learning course and learning method, support of study circle activity, career planning counseling, follow-up counseling, and counseling evaluation. According to the needs assessment, learner's analysis is conceived as the most important duty among the 4 sub-duties, and learner's analysis is regarded as second important duty by the counseling practitioners. Among the 11 tasks, providing learning information is the most important tasks among counseling practitioners, and analysis of learner's characteristics and needs is followed as second task. The duty system of the lifelong learning counseling and needs assessment data can be used as the basic data for lifelong education practitioners to conduct the duty of lifelong learning counseling efficiently and to support the lifelong learning plan according to learner's characteristics.

To analyze phytosociological characteristics of the Mt. Namsan nature park, Seoul, vegetation structure of north-east and south-west slopes, competition capability among species, vegetation structures of afforested species were studied with belt-transect and quadrat methods. And management plan of each vegetational zone was proposed by the results of this study and the other previous reports. Numbers of species and individuals of south-west slope were greater than those of north-east slope. But species diversity of northeast showed stability of 1.0, while that of south-west showed instability from 0.8 to 1.3. The floristic dissimilarity coefficient between two slopes showed 70-80% in which species composition between two slopes was much different. Quercus mongolica was a dominant species at north-east slope and Pinus densiflora at south-west slope. Competition capability among major species was resulted in deciduous trees>Robinia pseudoacacia>Populus alba ${\times}$ glandulosa>Pinais densiflora, Quercus mongolica>deciduous trees>Pinus densiflora. Afforested vegetation at the Mt. Namsan, especially Pinus koraiensis, Abies holophylla, Picea abies, etc showed poor growth rate. The goal of the Nam-san nature park management is to conserve natural ecosystem as it is and, if necessary, to accerlerate restoration of the disturbed ecosytem to its nature by minimum energy input as possible. Management proposal was made for six vegetational management zone ; P. derasitZoru forest zone, Q. mongolica forest zone, deciduous forest zone, afforestation zone, R. pseduoacacia zone and landscape planting zone.

골프장 건축 시 하부지반 구축을 위해 사용하는 잔석의 산화로 인해 중금속 용출이 발생할 수 있다. 용출된 중금속으로 인근 농업지역이 오염될 경우 인간의 식생활에 직접적인 영향을 미쳐 인체건강에 악영향을 끼칠 수 있다. 특히, 망간의 경우 식품을 통해 과다섭취할 경우 정신착란, 운동실조 등 다양한 신경학적 문제를 발생시키기 때문에 망간 오염에 대한 조사 및 관리는 필수적이다. 따라서, 본 연구는 최근 골프장이 건설된 부산시 일광 회룡리 일대 농업지역에서 망간 오염 평가를 위해 지표수, 퇴적물, 벼 작물을 채취하여 망간 농도 분석을 수행하였다. 골프장 유출조부터 시작되는 관개수로에서 지표수와 퇴적물 시료를 약 20 m 간격으로 채취하였으며, 관개수로의 구조에 따라 논을 4개의 구역(Area 1 - 4)으로 구분하여 논 토양과 벼 작물을 채취하였다. 벼 작물의 경우 뿌리, 줄기, 곡물 부분으로 나누어 채취하였으며, 퇴적물과 논 토양은 시료 내 존재하는 망간의 형태를 확인하기 위해 연속추출법을 통해 분석하였다. 분석 결과 지표수의 망간 농도는 골프장 유출조에서 하류로 갈수록 감소하는 경향을 보였으며, 하류에서의 망간농도는 상류에 비해 최대 88% 감소하였다. 퇴적물의 망간 농도는 논으로 연결되는 지점에서 20,000 mg/kg 이상의 높은 농도를 보였으며, 농업이 진행 중인 3, 5, 7월은 최대 약 25,000 mg/kg의 농도를 보였으나, 농업이 끝난 9월에는 최대 약 3,500 mg/kg으로 상대적으로 낮은 농도를 보였다. 논 토양의 망간 농도는 관개수로와 첫 번째로 연결되는 Area 1에서 1,600 mg/kg으로 측정되었으며, 이는 EPA에서 권고한 논 토양 망간 기준 1,000 mg/kg을 초과하는 농도로 확인되었다. 또한, 식물이 사용할 수 없는Residual 형태의 망간 농도는 변화가 없었으나, 식물이 사용 가능한 Acid soluble, Reducible, Oxidizable 형태의 망간 농도는 추수기 이후 80% 이상 감소하였다. 벼 작물의 곡물 망간 농도는100 - 200 mg/kg으로 USDA에서 발표한 쌀 곡물 망간 농도의 평균인 5 mg/kg보다 약 20배 이상 높게 검출되었다. 본 연구 결과를 통해 골프장 유출조로부터 발생하는 망간오염을 식별하고 주변 농업지역에 미치는 영향을 확인할 수 있었으며, 추후 골프장 운영으로 인한 환경오염에 대한 관리가 필요할 것으로 생각된다.

Constructed wetlands undergo biological and physical changes such as an increase in the proportion of arid plants due to the natural succession process after formation. It can adversely affect not only the purification function but also the habitat of species. As such, this study aims to identify environmental factors affecting biodiversity and propose management plans based on the monitoring results of physical environmental changes and the emergence of species in seven constructed wetlands selected based on the water depth and surrounding conditions among the lands purchased by the Nakdong River basin. We examined the environmental conditions and emergence of the Odonata, which is a wetland-dependent species, to predict the trend of changes in biodiversity and abundance. The results showed that the open water area decreased as the emergent plants spread to the deep water in 2015 compared to 2012 when they were initially restored to a depth of 0.2 to 1 m. While a total of 54 dragonfly species were observed, the habitat diversity, such as vegetation, water surface, and grassland, remained similar to the initial formation of the wetlands despite the expansion of the emergent plants. On the other hand, the number of Agrionidae species, which prefer areas with fewer aquatic plants, decreased between 2012 and 2015 due to the diminished water surface. The p-values of the differences in the number of species and population between wetlands by year were 2.568e-09 and 1.162e-08, respectively, indicating the statistically significant differences. The decrease in open water surface was found to have the greatest effect on the biodiversity and habitat density of dragonflies. The time-series survey of constructed wetlands confirmed that the spread of Phragmites communis, P. japonica, Typha orientalis, etc., caused a decrease in species diversity. It suggests that environmental management to maintain the open water surface area is necessary.
