  • 본 연구에서는 단각목의 일종인 소백옆새우(G. sobuegensis)를 대상으로 인공수로 하에서 pH 변화를 유도시킬 때 발생되는 개체의 표류행동에 대한 이동특성을 알아보았다. 본 종은 낮은 pH수준의 산성스트레스에서 회피행동이 현저하게 증가한다는 것을 알 수 있었으며, 또한 산성도에 따른 내성범위는 개체의 성숙도 즉 중소형보다 대형개체가 보다 민감하게 반응하는 것을 확인할 수 있었다. 특히 산성 스트레스에 의한 반응이 대형개체에 비해 소형과 중형개체에 있어서 매우 불규칙적으로 나타난 것은, 각종 수환경 변화에 대한 회피능력과도 같은 운동성의 차이 등을 고려해 볼 수 있었다. 전반적으로 인공 수로내의 소백옆새우 대부분 개체들은 전 시기에 걸쳐, pH4.5 이하의 낮은 수준에서 매우 민감하게 반응 한 후, 즉시 하류역 방향으로 수류의 움직임을 따라 능동적으로 회피 이동하는 특성을 보이는 것으로 나타났으며, pH3.0 이하의 강한 산성 스트레스 하에서는 오히려 회피능력을 상실하는 것으로 보여졌다. 또한 ANOVA분석결과, pH(F=353.415, p<0.0005)이외의 몇몇 환경 요인들 중 수온(F=66.596, p<0.0005)과 각 개체의 크기(F=71.386, p<0.0005)등도 낮은 산도에 의한 소백옆새우의 회피행동에 큰 영향을 미치는 주요한 요인이라는 것을 확인할 수 있었다.

  • The present study examined the effects of soybean-derived phosphatidylserine (SB-PS) on the learning and memory function and the neural activity in rats with trimethyltin (TMT)-induced memory deficits. The cognitive improving efficacy of SB-PS on the amnesic rats, which was induced by TMT, was investigated by assessing the Morris water maze test and by performing cholineacetyl transferase (ChAT), acetylcholinesterase (AChE) and cAMP responsive element binding protein (CREB) immunohistochemistry. A positron emission tomography (PET) scanning the rat brain was by performed administer 18F-Fluorodeoxy-glucose (18F-FDG). The rats with TMT injection showed impaired learning and memory of the tasks and treatment with SB-PS produced a significant improvement of the escape latency to find the platform in the Morris water maze at the 2nd day compared to that of the MCT group. In the retention test, the SB-PS group showed increased time spent around the platform compared to that of the MCT group. Consistent with the behavioral data, SB-PS 50 group significantly alleviated the loss of acetyl cholinergic neurons in the hippocampus compared to that of the MCT group. Treatment with SB-PS significantly increased the CREB positive neurons in the hippocampus as compared to that of the MCT group. In addition, SB-PS groups increased the glucose uptake in the hippocampus and SB-PS 50 group increased the glucose uptake in the frontal lobe, as compared to that of the MCT group. These results suggest that SB-PS may be useful for improving the cognitive function via regulation of cholinergic marker enzyme activity and neural activity.

  • Objectives : The purpose of this study was to examine the relationship of oral health behavior factors to oral health promotion behavior in dental hygiene students and nonhealth-related majors, to identify factors affecting their oral health promotion behavior and ultimately to provide information on the oral health promotion of college students and behavioral factors related to that. Methods : The subjects in this study were three-year-course dental hygiene students and two-year-course nonhealth-related majors in G college located in the city of Gwangju. A self-administered survey was conducted for 11 days from September 9 to 19, 2009, and the answer sheets from 473 respondents were analyzed. To look for connections between their major and the characteristics of their oral health promotion behavior, t-test was utilized, and t-test and one-way ANOVA were carried out to find out the relationship oral health promotion behavior by general characteristics. Besides, multiple regression analysis was employed to grasp factors affecting oral health promotion behavior. Results : Among the subfactors of oral health promotion behavior, the dental hygiene students statistically significantly outdid the nonhealth-related majors in thorough post-meal toothbrushing(p<0.01), toothbrushing method(p<0.001), use of fluorine-containing dentifrice(p<0.001) and good nutrition(p<0.05). But the latter statistically significantly outperformed the former in use of fluorine-containing rinse(p<0.001) and limited sugar intake(0<0.05). Regarding variables affecting oral health promotion behavior, the age group, whether to get a dental checkup over the last year and whether to use oral hygiene supplies were identified as the variables to impact on oral health promotion behavior. Specifically, the age group(dental hygiene students) and the get a dental checkup over the last year(nonhealth-related majors) had a greater impact. Conclusions : To promote the oral health of college students, comprehensive oral health education should be provided, which covers the importance of dental checkup, recommendation for the use of oral hygiene supplies, etc. Specifically, oral health education should be offered as one of general education courses in order for nonhealth-related majors to get into sound life habits and improve their oral health promotion behavior. To make it happen, required institutional measures should be taken.

  • The purpose of this study was to figure out related factors to the self-reported climacteric symptoms and the relationship among the health promoting behaviors, climacteric symptoms and degree of Sanhujori, the Korean traditional postpartal care. A cross-sectional survey design was employed in this study. The subjects were 108 middle-aged women who were non-hystrectomized and ranged in age from 40 to 60 years. They were selected in seoul and Kyoung-ki province, Korea, Data were collected from Oct.25 Nov. 10, 1997 by a structured questionnaire. The instruments used for this study were the revised health Promotion Lifestyle(HPLP) developed by Walker, Sechrist & Pender, and revised Climacteric Symptoms Scale developed by Chi, Sung Ai. the data were analyzed by the SPSS/$PC^+$ program using t-test, ANOVA and Scheffe test as a post hoc and Pearson Correlation Coefficient. The results of the study were as follows ; 1. The mean score of health promoting behaviors was low($2.42{\pm}0.35$). There were statistically significant differences in the score of health promoting behaviors according to the educational background, family income, marital satisfaction, whether or not taking a restorative food and degree of Sanhujori, especially the period (t=-2.07, F=2.60~7.57, p<0.05). 2. The mean score of score self-reported climacteric symptoms was 1.69%;99% of middle-aged women had symptoms. There were statically significant differences in the score of middle -aged women's self-reported climacteric symptoms according to the age, number of children, educational background, occupation, family income, marital satisfaction, whether or not receiving hormon replacement therapy (HRT) or consultation by a professional, perceived health status and self evaluation of Sanhujori(t=-2.04~3.69, F=2.87~11.63, p<0.05). 3. women's degree of Sanhujori was a positive correlation with health promoting behaviors(r=0.34, p=0.00) and negative correlation with the degree of self-reported climacteric symptoms(r=-0.19,p=0.03). 4. The influencing factors to the climacteric symptoms were self actualization, interpersonal support, and perceived health status among the health promoting behaviors with 57% of variance($R^2$=0.57). 5. The middle-aged women's type of coping pattern for the climacteric symptoms was classified as active behavioral coping, spiritual & psychological coping, and negative coping. In conclusion, to intervene the middle aged women's climacteric symptoms and develop nursing strategies for their health, health promoting behavior, especially ; self actualization, interpersonal support, and perceived health status should be considered. And, as the primary prevention strategy for women's health during the period of childbearing and also middle age, especially for the climacteric symptoms, Sanhujori should be reconsidered.

  • The purpose of this study is to classify elderly patient in long-term care facilities using RUG(Resource Utilization Group)-III. It is designed by measuring patient medical characteristics and medical staff time. Elderly patients are classified into 7 categories by clinical(medical and behavioral) hierarchical typology of patients. Through the tertiary split, all 44 groups are formulated. This classification is explained by each patient resource(staff time) utilization level which is called CMI(Case-Mix Index). Major findings are as follows; 1. The objects in this study were classified into 35 groups out of 44 groups. The most frequent category is clinical complex category(CCC; 38.9%). And extensive service category(ESC; 18.8%), reduced physical function category(RPC; 13.1%), special rehabilitation category(SRC; 12.8%), and impaired cognitive category(ICC; 0.00%) are followed. 2. The mean of total CMI was $1.02{\pm}0.36$, ranging from 0.68 to 1.44(1 vs 2.12). The mean of CMI of SRC is only 1.17 which should be the highest. The means of ESC and see are equally 1.20. The means of CMI of CCI, ICC, BPC, and RPC were 0.90, 0.75, 0.83 and 0.96, respectively. 3. The validity of this classification was tested. Trend-test using Regression Analysis was done in the secondary split level. SCC, CCC, ICC, and RPC which covered 68.4% of this research objects showed linear trend of CMI in interim classification. This results were statistically significant. 4. In clinical hierarchy, the trend were showed linearity. But the multiple comparison of categories using Scheffe-test showed that SRC, ESC and see had same level of CMI means and CCC and ICC, too. This results were statistically significant. Classifying elderly patients with RUG-III, the results showed partly linear trend in clinical hierarchy and in interim classification in conclusion. But, in clinical hierarchy, it was failed to show the consistent order of CMI. It can be explained by two reasons. One is that this research subjects were overlapped in each clinical hierarchy group. And the other is that the some of the characteristics for clinical hierarchy is not appropriate for them. For the further study, it needs to have proper sample size and to modify RUG-III to K-RUG to consider our.. medical environment.

  • 자폐적인 아동은 사회적 발달의 기초인 모-아 애착에서부터 왜곡되어 있고 특히 일치적 애착 행동들이 저하되어 있음을 볼 수 있다. 이를 개선하기 위해서는 일치적 행동들의 정상적 발달양상과 관련 요소를 파악하는 것이 선행되어야 하겠기에 자폐군과 정상군 총 20쌍의 모-아 놀이를 비교분석하였다. 그 결과 자폐군의 일치적 행동들은 정상군에 비해 저하되어 있고 발달 경과도 느렸으며 특히 16개월 이상부터는 현저한 차이를 보였다. 일치성과 상관이 있는 어머니의 양육행위는 애정적 표현을 하고 적절한 행동 멈춤을 보이며 아동의 행동을 기다려주는 것이었다. 모-아 상호집중의 저해요소는 지시적이고 간섭하고 학습중심적인 어머니의 놀이 행위와 아동의 무관심, 무반응, 과제수행의 실패 등이었다. 그러나 아동의 수준을 고려해 적당히 자극적인 접근을 하였을 때 상호집중이 유발되고 지속되는 것을 볼 수 있었다.

  • One of the important tasks for new parents, especially mothers, is to establish warm, mutually affirming interpersonal relationships with the new baby in the family, with the purpose of promoting the health development of the child and the well-being of the whole family. Nurses assess the quality of the behavioral characteristics of the maternal-infant interaction. The purpose of this longitudinal descriptive correlational study is to investigate the changes of the mother - infant interactions from postpartum 1 day to postpartum 8weeks of the transition to parenthood. The aim was to contribute to the development of theoretical under standing on which to base care toward promoting the quality of maternal - infant interaction. Data were collect ed directly by the investigator and at rained from Jul, 1, 1990 to Jun 8, 1991, Subjects were a random sample of 44 mothers, 44 who had a normal delivery (but with out other perinatal complications) at four general hospitals in Seoul. Instruments used were the Stainton Parent-infant Interaction Scale (1981). The first observations were made in the delivery room, followed by day 1, day 2, day 3 and 2 weeks, 4 weeks, 6 weeks and 8 weeks after, birth, for a total of 8 contacts. Observations in the hospital were made during the hour prior to scheduled feedings. The infant was placed beside the mother. Later contacts were made at home. Data analysis was don by computer using as SPSS program and included, Paired t-test, t-test and Pearson Correlation coefficient ; the results were as follows. 1. The daily maternal-infant interaction score for the initial contact ofter birth to 8 weeks postpartum had the lowest average score 5.21 and the highest 8.02(in a range of 0-10). This subject group of mothers needed Extra nursing supporting to promote their maternal-infant interaction. 2. The daily scores for the maternal-infant interaction tended to rise, showing a gradual improvement over the period of eight weeks. However, there were significantly different increases in maternal-infant interaction only from the first to second day (p=0.000) and from the fourth to sixth weeks ofter birth.(p=0.000) 3. When the seven items of maternal-infant interaction were evaluated items of maternal-infant inter action were evaluated separately, "Care taking for the baby" had the highest average score, 1.60(in a range of 0-2) and "Speaks to baby" the lowest, 0.8. All items, suggested the subjects' need of nursing intervention to promote maternal-infant interaction 4. There were positive correlations between certain general characteristics, namely, both a higher economic status (p=0.027) and breast feeding (p=0.021) and maternal-infant interaction.

  • Objective : To research Trends of studies about anti-inflammation and pain relief, obesity, and safety of herbal acupuncture therapy by analyzing domestic theses, published since 2001, about herbal acupuncture therapy. Methods : Domestic theses, published since 2001, mentioning anti-inflammation or pain relief, obesity, or safety of herbal acupuncture therapy were reviewed and analyzed. These theses were then classified by university, year, and subject. Results : The following results were obtained in this study. 1. Among published theses related to anti-inflammation effects of herbal-acupuncture, studies about arthritis comprised the most part, 52. In theses relating to causes of arthritis, 16 were about adjuvant, which was the most, followed by Type II collagen, LPS and carrageenan. Blood test, reactions of inflammation and revelation of cytokine and immune cellswere methods for evaluating anti-inflammation effect. The tendency of experimental methods was to focus on molecular biologic method. 2. In theses related to pain relief, many clinical attempts with herbal injection were carried out, and Carthami Flos and Scolopendrawere used most. Observing reduction of pain inducing factor and checking behavioral change were methods for evaluating pain relief. 3. In theses related to obesity, research focused on effects in association with spots on the body suitable for acupuncture. There were also attempts comparing effectiveness between single injections and complex injections. Astraball Radix, Angelica Gigantis Radix, Coicis Semen and Taeumjowetang were used. Evaluation of anti-obesity effects were by weight loss, food efficiency, blood lipid profile and evaluation of liver function. 4. In theses related to safety of herbal-acupuncture, Herba Chelidonii Chaenonelis Fructus, Clematis Florida Thunb, Corydalidis Tuber, Paeoniae Radix, and Carthami Flos which marked 2 theses each were most studied. Methods of evaluating safety were mostly by observing liver and kidney functions based on blood test, and by applying herbal injections to clinical treatment. Conclusion : Herbal acupuncture is being used in various ways associating with its anti-inflammation, pain relief and anti-obesity effect. Studies on efficacy and mechanism of herbal acupuncture are being conducted even at the molecular biology level.
