In the context of rapid temperature rise in mid-to-high latitude regions, cold region wetlands have become a hotspot for current wetland carbon cycle research due to their high sensitivity to climate change. Strengthening the monitoring of CO₂ fluxes in wetland ecosystems is of great practical significance for clarifying the carbon balance of wetlands and maintaining the ecological balance of wetland ecosystems in China's high latitude regions. In this study, the carbon flux (NEE, Net ecosystem exchange; GPP, Gross Primary Production; RECO, Ecosystem response) of Jingxin Wetland was monitored by eddy correlation method from August 2021 to March 2024.2022-2023 shows CO₂ sinks, absorbing 349.4 g C·m^-2·yr^-1 annually. The correlation analysis showed that Ta, VPD and PPFD were the main environmental factors affecting CO₂ flux in Jingxin wetland.

Coastline changes evolution of different intensities at all times under the influence of natural and anthropogenic effects. In this paper, we extracted the coastline of the Tumen River estuary from 1985 to 2020 using the digitizing method, verified the accuracy using the visual interpretation results, and analyzed the changes of the coastline of the Tumen River estuary through the area method and the baseline method. The results showed that the coastline showed an erosion trend during 35 years, with an average erosion rate of 0.05 m/year, an average erosion distance of 3.06 m, and an erosion area of 19.25 ha. Among the human activities that retarded the erosion of the coastline, these activities had a long-term impact on the natural morphology of the coastline.

Purpose: This study was to investigate depression in Korean-Chinese elder living in the Yanbian Korean Autonomous Prefecture in China. Methods: A cross-sectional community-based survey was conducted using face to face private interviews for elders aged over 59, who have been dwelling in the Yanbian Korean Autonomous Prefecture. The samples consisted of 183 Korean-Chinese and 182 Han-Chinese with the latter as a reference group. Data were collected from August 25 to September 20, 2011 and analyzed with the SPSS 18.0 program. The GDS (Geriatric Depression Scale) was used to measure elderly depression in the subjects. Results: In Korean-Chinese, the rate of depression was higher in those who had lower educational levels, and were economically supported by the government. And those who had depression showed lower scores in Chinese language proficiency, health status, and social supports, and had more chronic diseases. Factors having effects on Korean-Chinese elderly depression included perceived health status and subjective support. Conclusion: According to the results, for preventing the depression of Korean-Chinese, it is necessary to develop health management programs and social support networks, which were easy to approach.

철도는 대량수송 및 정시제 운행이라는 중요한 역할을 하면서도 다른 한편으로는 철도연변에 거주하고 있는 사람들에게 상당한 소음공해를 미쳐 정온한 생활환경을 누릴 권리를 침해하고 있음에도 불구하고 철도소음을 관리하는 기준이나 대책등이 아직 미미한 실정이다. 향후 5년 내에는 고속철도의 등장도 확실하지만 기존 재래식 철도에 대한 소음 실태 자료마저 충분치 않아 철도연변의 소음진동 문제를 해결하기 위한 기본적 수단인 소음 기준 제시를 위해서는 폭넓은 기초 자료확보와 새로운 관련연구가 요청되었다. 이러한 필요성에 따라 전기기관차를 중심으로 영동선, 중앙선, 태백선, 경인선, 경원선 및 대도시 도심지를 관통하는 호남선 및 경부선 중에서 측정환경이 양호한 22개 지역을 선정하여 기존 철도의 구간별 30분, 1시간, 2시간, 3시간 등가소음도를 측정하였고 선로의 조건, 열차의 종류 및 속도, 거리권별 등에 따른 개별열차 통행시의 소음특성을 조사하여 철도소음의 기준 설정과 방지대책 강구시에 활용할 수 있도록 하며, 열차 통행속도로부터 최고소음도를 추정하여 주변지역의 등가소음도를 산정할 수 잇는 예측식을 도출하여 측정방법 개정에 활용하고, 그리고 선로변에 위치한 공동주택을 대상으로 층별 철도소음 노출도와 열차통과시의 공동주택 실내.외의 소음도를 비교조사하여 벽체 차음 효과를 조사하였고 철도소음에 대한 주민반응 조사를 하였다.

청국장은 삶은 콩을 고초균으로 불리는 Bacillus subtilis를 이용하여 발효시킨 전통조미식품으로, 최근 혈전용해효소의 함유뿐만 아니라 항돌연변이, 항고혈압, 항암효과 등이 검증되어 기능성 식품으로서 새로운 관심의 대상이 되고 있다. 그러나, 청국장의 독특한 불쾌취는 특히 젊은 세대의 섭취 기피 원인이 되고 있고, 찌개 형태의 단순한 조리법은 이용 방법면에서 한계를 가지고 있다. 따라서 영양이 풍부하고 우수한 생리활성효과를 가진 청국장의 계승 발전과 소비 진작을 위하여 청국장의 기호성, 편의성 등을 강화하고 청국장의 제조법을 간편화하는 연구가 필요한 실정이다.

The Purpose of this study was to identify the dimensions and pattern types for the perception of Korean traditional food and to find the determinants of the pattern types, taking food cultural background into account. Data were factor and cluster analyzed, and the results revealed two different dimensions and pattern types. Descriptive statistics showed that perceptional pattern types, i.e., traditional-modern pattern and tradition-oriented pattern, are likely to vary depending on socio-demographic and cultural background of Korean traditional food in Korea. Similarities and differences in perceptional pattern types are discussed, and future implications for food and nutrition specialists and food marketers are provided.
