본 연구는 부정적인 삶의 사건과 일상적인 근심으로 인한 스트레스가 초고령 노인의 삶의 만족에 미치는 영향을 확인하고 나아가서 이러한 영향에 대한 심리사회적 자원의 완화효과를 검증하였다. 213명의 지역사회에 거주하는 85세 이상 노인을 대상으로 기술적 분석, 회귀분석 등이 실시되었다. 주요분석결과를 보면 다음과 같다. 첫째, 초고령 노인들은 건강문제를 가장 중요한 삶의 사건이나 일상적인 근심으로 제시하였다. 둘째, 일상적인 근심으로 인한 스트레스, 수입수준, 자녀와의 동거, 기능손상수준은 초고령 노인의 삶의 만족에 영향을 미치는 데 반해 부정적인 삶의 사건으로 인한 스트레스는 유의미한 영향을 미치지 못하였다. 셋째, 심리사회적 자원 가운데 자녀로부터의 정서적 지지와 노인의 자아존중감은 일상적인 근심으로 인한 스트레스가 초고령 노인의 삶의 만족에 미치는 부정적 영향을 감소시키는 완화효과가 확인되었다. 이러한 연구결과에 따라 자녀로부터의 정서적 지지의 활성화, 자아존중감 향상을 위한 프로그램의 적용 등 초고령 노인의 삶의 만족을 향상시키기 위한 실천적 함의가제시되었다.

본 연구는 자연스럽게 스트레스 반응이 유발되는 치과 진료를 경험한 4-9세 아동 85명을 대상으로 스트레스적 사건에 대한 아동의 회상에 아동의 인지 및 사회 정서적 개인차 변인들이 어떤 영향을 미칠 수 있는 가를 살펴보고자 하였다. 본 연구의 결과는 스트레스 수준과 아동의 기억 수행은 전반적으로 부적 상관 관계가 있는 것으로 나타나 국외 선행 연구들의 결과를 반복 검증하였다. 그러나 보다 흥미로운 결과는 스트레스적 경험에 대한 아동 회상보고의 정확성에 아동의 인지적(예: 수용적 언어 능력, 작업 기억 역량) 개인차 특성과 정서적(예: 평소 아동의 우울 및 불안 상태, 정보 부호화 시 아동의 불안 정도) 개인차 특성들이 유의한 영향을 미칠 수 있다는 점이다. 이와 같은 결과는 치명적인 범죄 사건과 관련하여 아동의 회상 보고를 해석할 경우 아동의 인지 및 정서적 개인차 특성들도 신중하게 고려되어야 함을 함의한다. 궁극적으로 본 연구는 다양한 개인차에 따른 아동의 기억 특성에 대한 심화된 지식을 규명하고 실제 수사 면담 시 아동의 개별적 특성을 고려한 면담 방식의 구축에 유용한 정보를 제공하는 데 그 의의를 두고자 한다.

Both ethanol and water extracts of unossified velvet antler were found to exhibit a significant immuno-stimulating activity as measured by carbon clearance test in mice, a remarkable anti-fatigue effect in weight-loaded forced swimming performance in mice, a significant anti-stress effect on immobilization in rats. The antler extracts also showed a weak but significant anti-thrombotic activity. These findings are indicative of adaptogenic properties of antlers and their normalizing effects during stressful condition.

Under the extreme change of the environment, animals react physiologically to adapt to the stress and secrete catecholamines. Cold exposure is a kind of the environmental stress. Author tried to determine the amount of catecholamines in rat urine as a parameter of physiological response to cold stress. Urinary catecholamine was measured by using HPLC with fluorescence detector, cation exchange column prepacked with Bio·Rex 70 and ammonium pentaborate as catecholamine eluent. The amount of dopaminc in normal state rat urine was 42.0 ng, but under the low temperature of $5^{\circ}C$, the dopamine amount was increased to 221.25 ng/5 ml. Above findings are suggesting that catecholamine secretion, especially dopamine, increases in the stressful condition such as cold exposure.

Purpose : This study is to understand the reactive oxygen which is expected to be a causative factor of aging condition including dementia, atherosclerosis, even cancer. Methods : The reactive oxygen is generated usually when people do very hard exercise or is under severe stressful situation or in unhealthy environment and as a protective reaction to reactive oxygen, human body releases antioxidant enzyme systems like superoxide dismutase (SOD), catalase, glutathione peroxidase (GPX), glutathion-S-transferase (GST) and non-enzymetic antioxidant systems like glutathione, ascorbate, $\beta$-carotene, vitimin E. Results : Nowadays, we are getting more interested in the generation of reactive oxygen especially in the area of physical education, food and nutrition, alternative medicine etc. Conclusion : The study of reactive oxygen in patients with musculoskeletal disease is also required and among various physical therapeutic approaches, the method of general coordinative manipulation is considered more necessary.

Heat shock protein 70(HSP70) is induced by elevated temperature and many other types of stresses in cell. HSP70 ensures cell survival under stressful condition that would lead to irreversible cell damage and ultimately to cell death. HSP70 plays essential role in the synthesis, transport, and folding of proteins and is often refferred to as molecular chaperones. Increased levels of HSPs occur after arthritis, infection, imflammation, autoimmune disease and CNS injury such as infarction, ischemia, seizure and Alzheimer's disease. Also, HSP70 increases resistance to apoptosis. The recent studies that the expression of the HSP has been processed at various field. However, they an still relatively line studied in clinically application. This review summarizes the fundamental knowledge of HSP.

Availability of nutrients is known to influence marine primary production; and it is of general interest to see how nutrient limitation mediates phytoplankton responses to solar ultraviolet radiation (UVR, 280-400 nm). The red tide diatom Skeletonema costatum was cultured under nitrate (N)-limited and N-replete conditions and exposed to different solar irradiation treatments with or without UV-A (315-400 nm) and UV-B (280-315 nm) radiation. Its photochemical quantum yield decreased by 13.6% in N-limited cells as compared to that in N-replete ones under photosynthetically active radiation (PAR)-alone treatment, and the presence of UV-A or UV-B decreased the yield further by 2.8 and 3.1%, respectively. The non-photochemical quenching (NPQ), when the cells were exposed to stressful light condition, was higher in N-limited than in N-replete grown cells by 180% under PAR alone, by 204% under PAR + UV-A and by 76% under PAR + UV-A + UV-B treatments. Our results indicate that the N limitation exacerbates the UVR effects on the S. costatum photosynthetic performance and stimulate its NPQ.

Iris laevigata is geographically restricted and legally protected in Korea. In this study, a mesocosm study was conducted to examine the effects of environmental conditions such as water levels and soil nutrient conditions on the growth and survival of I. laevigata seedlings. Complete submergence lowered the total number of leaves, biomass, and survival rates. A rise in soil nutrients increased overall seedling growth and increased tiller numbers via the promotion of asexual reproduction. Also, we found that the lowest measured values of seedlings are associated with the most stressful condition due to the interaction of low soil nutrients and high water levels. I. laevigata seedlings, however, are distributed in low-nutrient habitats such as floating mat, even though they do not grow well under these conditions. This study suggests that I. laevigata does not prefer low-nutrient condition but choose another benefit such as low competition. Also, the water level must be lower than the seedling height for effective growth and management of I. laevigata.

Adaptive development of early stage embryo is well established and recently it is explored that the mammalian embryos also have adaptive ability to the stressful environment. However, the mechanisms are largely unknown. In this study, to evaluate the possible role of aquaporin in early embryo developmental adaptation, the expression of aquaporin (AQP) 5 gene which is detected during early development were examined by the environmental condition. To compare expression patterns between in vivo and in vitro, we conducted quantitative RT-PCR and analyzed localization of the AQP5 by whole mount immunofluorescence. At in vivo condition, Aqp5 expressed in oocyte and in all the stages of preimplantation embryo. It showed peak at 2-cell stage and decreased continuously until morula stage. At in vitro condition, Aqp5 expression pattern was similar with in vivo embryos. It expressed both at embryonic genome activation phase and second mid-preimplantation gene activation phase, but the fold changes were modified between in vivo embryos and in vitro embryos. During in vivo development, AQP5 was mainly localized in apical membrane of blastomeres of 4-cell and 8-cell stage embryos, and then it was localized in cytoplasm. However, the main localization area of AQP5 was dramatically shifted after 8-cell stage from cytoplasm to nucleus by in vitro development. Those results explore the modification of Aqp5 expression levels and location of its final products by in vitro culture. It suggests that expression of Aqp5 and the roles of AQP5 in homeostasis can be modulated by in vitro culture, and that early stage embryos can develop successfully by themselves adapting to their condition through modulation of the specific gene expression and localization.
