Purpose: This study was done to identify factors (pain stress, perceived stress, pain disability, fatigue, depression) strategies used by elders to cope with pain based on their type of pain belief. Method: Data were collected from 314 elders in community settings in Seoul from September to December of 2007. Cluster analysis, t-test, and ANOVA were used to analyze data. Result: The types of pain belief were classified as the following groups: Self-blame, Enduring & Mysterious, and Short-term & Understandable. Perceived stress (t=2.36, p=.02), social support (t=2.24, p=.03), extent of pain relief (t=2.39, p=.02), and duration of pain relief (t=2.09, p=.04) were important factors for active and passive coping in the Self-blame group. Pain stress (t=2.39, p=.01) and depression (t=-3.99, p=.00) were significantly related to the active coping in the Enduring & Mysterious group. Perceived stress (t=2.55, p=.01) was an important factor in the passive coping in the Short-term & Understandable group. Conclusion: Considering different types of pain belief in elders and factors that are significantly related to different coping strategies, future nursing interventions should be population specific to encourage active coping strategies and to decrease passive coping strategies.

The purpose of this study is to find the difference of the climacteric symptoms and quality of life according to hormone replacement therapy (HRT) in climacteric women. The research design was a descriptive survey with questionaries. A convenience sample of 181 climacteric women aged 45-65 who had climacteric symptoms were selected in Kwangju city, Korea. Sixty-six climacteric women among those subjects were receiving HRT at K university hospital in Kwangju city. Data were collected by the interview with questionaries from Feb 3. 1999 to March 25, 1999. Climacteric symptoms were measured using scores developed by Neugarten(1965) and modified by Park(1989), and the quality of life scale related to climacteric symptoms developed by Hildtich(1996) and modified Kim(1998). Data were analyzed by $x^2$-test, t-test, ANOVA and Pearson's correlation procedures, using SAS/win PC+. The results were as follows ; 1. No statistically significant differences were found between the receiving HRT group and not receiving HRT group in demographic, obstetrical and health related characteristics. 2. There were no significant difference on the climacteric symptoms between the group of women receiving HRT (score 2.4) and the group of women who were not (score 2.6) except psychological area (t= 2.407, p= 0.017). 3. The quality of life of the group of women receiving HRT was significantly higher than that the group of women who were not (t=2.151, p=.032). 4. The quality of life of the group of women receiving HRT were high scores There were significantly high of the quality of life in the vaso-motor change area (t=2.634, p= 0.009), psycho-social change area (t=3.239, p=0.001), and physical change area (t=2.031, p=0,043) in the group of receiving HRT compared to not receiving HRT group. 5. The variables showed significantly differences on the degree of climacteric symptoms of the group of women not receiving HRT were the subjective health state (t=15.81, p=0.000), age (t=7.50, p=0.007), feeling of menopause (t=30.88, p=0,000) and climacteric periods (t=8.66, p=0.003), and receiving HRT were number of para (t=3.95, p=0.050) and feeling of menopause (t=3.94, p=0.050). 6. The variables showed significantly difference on the quality of life of the group of women not receiving HRT were the subjective health state (t=4.14, p=0.044) and feeling of menopause (t=10.86, p=0.001). 7. There were significantly positive correlations between the climacteric symptoms and the quality of life in climacteric women (r=0.512, p=0.000).

Let ${\mathcal{L}}_2=(-{\Delta})^2+V^2$ be the $Schr{\ddot{o}}dinger$ type operator, where nonnegative potential V belongs to the reverse $H{\ddot{o}}lder$ class $RH_s$, s > n/2. In this paper, we consider the operator $T_{{\alpha},{\beta}}=V^{2{\alpha}}{\mathcal{L}}^{-{\beta}}_2$ and its conjugate $T^*_{{\alpha},{\beta}}$, where $0<{\alpha}{\leq}{\beta}{\leq}1$. We establish the $(L^p,\;L^q)$-boundedness of operator $T_{{\alpha},{\beta}}$ and $T^*_{{\alpha},{\beta}}$, respectively, we also show that $T_{{\alpha},{\beta}}$ is bounded from Hardy type space $H^1_{L_2}({\mathbb{R}}^n)$ into $L^{p_2}({\mathbb{R}}^n)$ and $T^*_{{\alpha},{\beta}}$ is bounded from $L^{p_1}({\mathbb{R}}^n)$ into BMO type space $BMO_{{\mathcal{L}}1}({\mathbb{R}}^n)$, where $p_1={\frac{n}{4({\beta}-{\alpha})}}$, $p_2={\frac{n}{n-4({\beta}-{\alpha})}}$.

The objective of this study was to determine storage stability and antioxidant effect of T1, ascorbic acid (0.6%); T2, ethanol extracts of Bacillus polyfermenticus (5%); T3, mixture with ascorbic acid (0.3%), and ethanol extracts of B. polyfermenticus (2.5%) during the storage period. The pH of sausage decreased constantly during storage (p<0.05). Thiobarbituric acid reaction substance (TBA) values were lower in all treated samples compared to the control (p<0.05). Longer storage periods resulted in higher TBA values (p<0.05). Volatile basic nitrogen (VBN) value in T1, T2, and T3 were significantly lower than control (p<0.05). The $L^*$ value of T1, T2, and T3 had higher than control. The $a^*$ value of T2 was significantly lower than control, T1, and T3 during storage period (p<0.05). The $b^*$ value of T2 had significantly higher compared to the other sausage samples during storage period (p<0.05). Total microbial counts in the sausages samples significantly increased as storage period increased (p<0.05). Further studies are needed to develop various meat products to extend the storage stability using B. polyfermenticus SCD.

The purpose of this study was to investigate the effect of combined exercise on injury risk factors of lower extremity during landing. Ten sports talented athletes participated in this study. Sports talented athletes participated in a combined exercise (sports talented exercise, coordination) for 16 weeks. A three-dimensional motion analysis was performed using eight infrared cameras (sampling rate of 100 Hz), one force plate, and electromyography system (sampling rate of 1000 Hz) during landing. Kinetic, and kinematics analysis including average impulsive force, angle of lower extremity, vertical stiffness, onset of muscle activation were calculated by Matlab2009a software. Paired t-test was performed at alpha=.05. The average impulsive force in landing phase was not statistically significant (t=-.748, p=.474). The hip joint angle was more decreased in post test compared to pre test (E1: t=2.682, p=.025, E2: t=5.609, p=.000, E3: t=2.538, p=.032). The knee joint (E1: t=-.343, p=.739, E2: t=1.319, p=.220, E3: t=.589, p=.570) and ankle joint (E1: t=.081, p=.937, E2: t=.784, p=.453, E3: t=.392, p=.704) angle were tended to decrease after combined exercise. The vertical stiffness was tended to decrease after combined exercise (t=1.972, p=.080). Onset of quadriceps femoris (t=.698, p=.503) and medial gastocnemius (t=1.858, p=.096) were tended to be faster than biceps femoris (t=-.333, p=.747) after combined exercise. Although thses findings were not statistically significant except on a hip joint angle, risk factors of lower extremity such as joint angle, vertical stiffness and onset of quadriceps femoris, medial gastrocnemius were positively changed after the combined exercise but an additional training for improved onset of biceps femoris would be required in the future.

돼지 뒷다리 부위를 동일한 비율의 양념액((T1, 간장소스; T2, 김치소스; T3, 새우젓소스; T4, 양파소스)에 침지하여 $1{\pm}1^{\circ}C$에서 30일간 저온에서 숙성기간 동안 양념 돈육의 품질 특성을 측정한 결과는 다음과 같다. 숙성기간동안 pH는 T3구가 가장 높게 나나났으며(p<0.05), 염도와 당도는 T1구가 높았다. 보수력은 T3를 제외하고는 숙성기간 동안 유의적인 차이가 없었다(p>0.05). 전단가는 T1구와 T4구는 숙성기간이 경과함에 따라 증가하였다(p<0.05). VBN은 T1구와 T3구는 숙성 20일까지 증가하다 30일에 다시 감소하였으며, T2구와 T4구는 숙성 20일 이후 급격히 증가하였다(p<0.05). TBARS는 T1구는 숙성 초기에 비해 숙성 20일 이후 크게 증가하였으며(p<0.05), T2구는 전 숙성기간 동안 큰 차이를 나타내지 않았다. 표면육색의 경우 L*값은 숙성 초기에 비해 숙성 말에는 감소하는 경향을 나타내었으며, a*값과 b*값은 숙성기간에 따라 T2구는 증가하고 T4구는 감소하였다. 심부육색에서 L*값은 숙성기간에 따라 T1구와 T3구는 낮아졌고 T4구는 유의적인 차이를 보이지 않았다. a*값과 b*값은 숙성기간에 따라 모든 처리구에서 증가하는 경향을 나타내었다. 총균수는 대부분 숙성 10일까지는 상승하다 숙성 말기에는 다소 감소하는 경향을 나타내었다. 처리구 간에 T3구는 숙성 초기부터 높게 나타났다(p<0.05). 대장균 수는 T4구를 제외한 나머지 처리구들에서는 숙성기간에 따라 감소하였다. 유산균 수는 T3구를 제외한 나머지 처리구들은 숙성기간에 따라 감소하는 경향을 나타내었다. 관능검사 결과 숙성기간에 따라 일정한 경향은 나타나지 않았으며 숙성 초기에 T4구에서 향, 풍미, 연도가 다른 처리구들보다 높게 나타났으며, 숙성 10일과 20일에는 T1구가 모든 항목에서 높은 점수를 나타내었다. 본 연구결과를 종합하면 처리구 간에 주목할 만한 품질의 차이는 나타나지 않았으며, 각 처리구마다 각각의 고유한 품질 특성을 나타냄으로써 숙성 양념육으로서의 가치를 가질 수 있을 것으로 판단된다.

This study was carried out to investigate the effects of feeding the broilers that are exposed to extreme heat stress by control of inverse lighting times with night restricted feeding of extreme heat diet(EHD1, 2: extreme heat diet) containing different amount of soy oil, molasses, amino acids and vitamin C on short chain fatty acid and blood lipid profile. 300 broiler chickens(Abaica strain) were randomized into four dietary treatment groups according to a randomized block design on the day they were hatched. The four dietary treatment groups were: T1(EHD 1, 10:00~19:00 Dark, 19:00~10:00 Light), T2(EHD 2, 10:00~19:00 Dark, 19:00~10:00 Light), T3(EHD 1, 09:00~18:00 Dark, 18:00~09:00 Light), T4(EHD 2, 09:00~18:00 Dark, 18:00~09:00 Light). The body weight gain of the broilers was highest in T2, and high in order T1, T4, T3(p<0.05). Weights of the lymphoid organ, thymus and bursa of Fabricius were high in T1, T2 as compared to T3, T4 but spleen was lower in T4 than T1, T2, T3(p<0.05). Blood triglyceride, total cholesterol and glucose were higher in T1, T2 than T3, T4(p<0.05). LDL-C was high in orderT4, T3, T2, T1 but HDL-C showed the opposite trend(p<0.05). Blood concentrations of IgG, IgG and IgM were higher in T1, T2 than inT3, T4, but the corticosterone concentration decreased significantly in them. In T1 and T2, Lactobacillus in the feces increased, but total aerobic bacteria, E.coli, coliform bacteria was decreased rather significantly, compared with those in T3 and T4(p<0.05). Concentrations of acetic acid, propionic acid and total SCFA in cecum were high in order T2, T1, T3, T4, but butyric acid, isobutyric acid, valeric acid, isovaleric acid were lower in T1, T2 than in T3, T4 (p<0.05).
