최근 연구들은 생존 맥락에서의 대상 기억이 다른 여러 맥락 조건들에서보다 더 정확함을 보고하고 있다(예, Nairne 등,). 본 연구에서는 이러한 생존 맥락의 효과가 과제와 무관한 대상의 위치에 대한 기억에서도 나타나는지를 알아보고, 대상 위치 기억의 성차가 맥락에 따라 달라지는가를 살펴보고자 두 개의 실험을 진행하였다. 참가자들은 생존 맥락이나 혹은 이주 맥락 중 하나의 맥락 하에서 여러 위치에 순차적으로 제시된 사진(실험 1)이나 혹은 단어(실험 2)에 대한 맥락 적합도를 평가하는 과제를 수행한 후, 각 자극에 대한 회상 검사와 위치 기억 검사를 받았다. 실험 결과, 두 개의 실험 모두에서 생존 맥락 조건에서의 대상에 대한 회상율이 이주 맥락 조건에 비해 더 높은 것으로 나타났다. 위치 기억의 경우는 여성이 남성보다 더 좋은 것으로(실험 1), 그리고 생존 맥락에서 더 정확한 것으로(실험 2) 나타났으며, 자극의 종류 및 제시 방식에 따라 기억맥락 조건과 성별간의 상호작용 효과가 나타났다. 이 결과는 위치 기억에 있어서 기억의 부호화 맥락이 성별에 따라 다른 영향을 미치고 있음을 시사하는 것이다. Recent studies report that in terms of object memory, survival context has mnemonic advantage over other context conditions (e.g., Nairne et al, 2007). The present experiments explored whether this effect can also affect task-irreverent object location memory, and tested whether the context can change gender difference in object location memory. Participants were asked to rate the relevance of pictures presented at random locations (experiment 1) or words (experiment 2) under survival context or moving context. After rating the pictures or words, they answered recall test and location retrieval test. The results revealed higher accuracy in memory for objects encoded under survival context. Moreover, survival processing enhanced location memory, and the survival advantage in location memory emerged among woman.

Objective-The Korean Longitudinal Study on Health and Aging (KLoSHA) was developed 1) to estimate the prevalence, incidence and progression of common geriatric diseases; 2) to determine the risk factors for common geriatric diseases and to develop preventive strategies by managing potentially modifiable determinants; 3) to investigate the influence of common geriatric diseases on the quality of life and general health status; 4) to evaluate the levels of health and functional status of Korean elderly persons. Methods-The KLoSHA was designed as a population-based prospective cohort study on health, aging and common geriatric diseases of Korean elders aged 65 years and over. The baseline study of the KLoSHA was conducted from September 2005 through September 2006 in Seongnam. Follow-up studies will be performed at 4-year intervals without an endpoint. Results-At the baseline study, 992 subjects (714 randomly sampled elderly subjects aged 65 years or over, 278 volunteers aged 85 years or over) were enrolled and completed the study. Prevalences and risk factors of common geriatric disorders in Korean elders were estimated, and the normative data of neuropsychological measures, general health parameters, and laboratory tests were drawn. Conclusion-The KLoSHA may not only provide comprehensive epidemiological data on the health status and common geriatric disorders of Korean elders, but also may stimulate comprehensive multidisciplinary and interdisciplinary researches on aging and geriatric disorders and contribute to policy formulation and planning of health management programs and social services in Korea.

Since the Industrial Revolution, mankind faced with the problem of global warming. Each country effort to reduce greenhouse-gases emissions constantly. In the case of Korea, they declared that they will reduce greenhouse-gases voluntarily at “intergovernmental Panel on Climate Change” held in Cancun, Mexico, in 2010. In addition, the government said that they would decrease to 30% of greenhouse-gases emissions figure in 1990 until 2020. Furthermore, they will effort to reduce greenhouse-gases emissions continuously. In Korea, fisheries research of greenhouse-gases is in the beginning stages. Therefore, the generated greenhouse-gases in fisheries should be reduced. It means that we need to quantify the emission of greenhouse-gases. In this study, we proposed a quantitative analysis method about greenhouse-gases emissions in fisheries. The greenhouse-gas emissions were derived for producing 1kg of round weight of fish and 1 ㎏ of edible weight of fish quantitatively. In addition, we derived annual greenhouse-gases emissions using the greenhouse-gases emissions for producing 1 ㎏ round weight of fish and the annual production. As a result, the present study will be based for reducing greenhouse-gases emissions.

Objective: Alternate ascending/descending directional navigation (ALADDIN) is a novel arterial spin labeling technique that does not require a separate spin preparation pulse. We sought to compare the normalized cerebral blood flow (nCBF) values obtained by ALADDIN and dynamic susceptibility contrast (DSC) perfusion magnetic resonance imaging (MRI) in patients with primary brain tumors. Materials and Methods: Sixteen patients with primary brain tumors underwent MRI scans including contrast-enhanced T1-weighted imaging, DSC perfusion MRI, and ALADDIN. The nCBF values of normal gray matter (GM) and tumor areas were measured by both DSC perfusion MRI and ALADDIN, which were compared by the Wilcoxon signed rank test. Subgroup analyses according to pathology were performed with the Wilcoxon signed rank test. Results: Higher mean nCBF values of GM regions in the bilateral frontal lobe, temporal lobe, and caudate were detected by ALADDIN than by DSC perfusion MRI (p < 0.05). In terms of the mean or median nCBF values and the mean of the top 10% nCBF values from tumors, DSC perfusion MRI and ALADDIN did not statistically significantly differ either overall or in each tumor group. Conclusion: ALADDIN tended to detect higher nCBF values in normal GM, as well as higher perfusion portions of primary brain tumors, than did DSC perfusion MRI. We believe that the high perfusion signal on ALADDIN can be beneficial in lesion detection and characterization.

붐 방제기의 경우 붐에 노즐을 배치하여 작물에 근접한 위치에서 농약을 정밀 살포하며, 스피드 스프레이어와 다르게 농약의 낭비를 줄일 수 있으며, 농약의 살포량을 제어하기 쉬운 장점이 있다. 본 연구에서는 붐식 스피드 스프레이어 개발을 위한 설계 인자를 도출하기 위한 사전인자 조사로 국내 시판되어지고 있는 노즐의 압력, 거리 변화, 블로워의 풍속변화에 따른 분무량을 측정하였다. 실험에 사용된 노즐은 A사에서 판매되고 분무경이 다른 5가지 노즐과 Disk 타입의 노즐 1종을 사용하였다. 압력은 5수준(0.5, 1, 1,5, 2 MPa)으로 변화시켰으며, 거리는 5수준(0.3, 0.6, 0.9, 1.3, 1.5 m), 블로워의 풍속변화는 3수준(29, 35, 41 m/s )으로 하여 측정하였다. 측정결과 압력 0.5 MPa, 거리 1.5 m, 풍속 29 m/s에서도 90%의 약제가 도달하였다. 따라서 낮은 압력에서 과수의 최대거리 까지 많은 양의 약제를 보내야하는 부분에서 풍속을 29 m/s 로 할 경우 모든 노즐이 사용하기에 적합하다고 판단된다.
