The olfactory organ of Carassius auratus and C. cuvieri was compared morphologically and morphometrically using stereomicroscopy and statistical program (SPSS version 18.0). The external morphology of the olfactory organ consists of the open semicircular anterior and posterior nostril, and nasal flap. The internal structure showed the oval rosette consisting of several lamellae arranged radiately. In statistical analysis of standard length (SL), olfactory lamellar number (LN), and SL/LN ratio between two species using independent two sample t-test and Pearson's correlation and coefficient, C. cuvieri is the longer SL than that of C. auratus and C. auratus LN (14~20) is lager than that of C. cuvieri (14~16) (P<0.001) and C. auratus LN/SL ratio (12.7±0.7%) is larger than that of C. cuvieri (8.2±0.6%). These results suggest that i) open semicircular nostrils is functional morphology to offset the boundary layer and ii) the lager LN of smaller C. auratus may be a morphological adaptation to reflect its higher olfactory dependence than C. cuvieri and iii) such interspecific difference in LN and LN/SL ratio could be applied as a new taxonomic trait for identification.

Purpose: The purpose of this study was to identify the differences in preference for terminal care between hospitalized patients and nurses. Methods: A cross-sectional descriptive design was used in 79 patients and 107 nurses. The data were collected from August to October 2011, using the Preference for Care near the End of life Scale - Korean Version (PCEOL-K) with 5-point scale of 26 items. The reliability of the tool was Cronbach's ${\alpha}=.74$. Results: The mean score (SD) of PCEOL-K's sub-dimensions in nurses' priority was: (a) pain $3.70{\pm}0.63$, (b) spirituality $3.63{\pm}0.61$, (c) family $3.40{\pm}0.70$, (d) autonomous decision making $2.30{\pm}0.66$, and (e) decision making by healthcare professionals $2.14{\pm}0.64$. In patients' priority, the $M{\pm}SD$ score of each sub-dimension was: (a) pain $3.86{\pm}0.65$, (b) family $3.83{\pm}0.57$, (c) decision making by healthcare professionals $3.37{\pm}0.85$, (d) spirituality $3.01{\pm}0.80$, and (e) autonomous decision making $2.43{\pm}0.63$. Results indicated significant differences between nurses and patients regarding decision making by healthcare professionals (t=-11.28, p<.001), family (t=-4.66, p<.001), and spirituality (t=5.71, p<.001). Conclusion: The PCEOL-K of patients was higher than nurses'. A terminal care program for hospitalized patients at the end of life should be planned according to the results of PCEOL-K in nurses and patients.

The purpose of this study was to examine the degree of successful aging and to investigate influencing factors of it in elderly to types of gender. Subjects were 73 male elderly and 77 female elderly, total 150 elderly living at K city in C province, from May to June, 2012. The data were analyzed using the SPSS Win 18.0 program for $X^2$ test, t-test, Pearson's correlation coefficients and multiple regression analysis. The correlated factors of successful aging among male elders included life satisfaction(r=.525, p<.001), family support(r=.355, p=.004), depression(r=-.555, p<.001) and loneliness(r=-.437, p<.001). Those of successful aging among female elders included life satisfaction(r=.607, p<.001), leisure satisfaction(r=.679, p<.001), family support(r=.784, p<.001), depression(r=-.516, p<.001), loneliness(r=-.644, p<.001) and self-transcendence(r=.576, p<.001). Life satisfaction and depression were statistically significant influencing factors of successful aging in male elders. Especially in the cases of female elders, life satisfaction, depression, family support and self-transcendence affected to successful aging. Life satisfaction, depression, family support, and self-transcendence were explained 52.9% in perception of successful aging among elders. This study suggests that life satisfaction, depression, family support, and self-transcendence will be considered in enhancing the successful aging promoting care and welfare designed for types of gender.

An in vitro study was conducted to examine the effect of monensin or fish oil addition on bio-hydrogenation of $C_{18^-} unsaturated fatty acids and CLA production by mixed ruminal bacteria when incubated with safflower oil. Commercially manufactured concentrate (1%, w/v) with safflower oil (0.2%, w/v) were added to mixed solution (600 ml) of strained rumen fluid and McDougalls artificial saliva (control). Monensin $Rumensin^{(R)}$, 10 ppm, w/v, MO), mixed fish oil (0.02%, w/v, absorbed to 0.2 g alfalfa hay, FO) or similar amounts of monensin and fish oil (MO+FO) to MO and FO was also added into the control solution. All the culture solutions prepared were incubated in the culture jar anaerobically at $39^{\circ}C$ up to 12 h. Higher pH (p<0.047) and ammonia concentration (p<0.042) were observed from the culture solution containing MO at 12 h incubation than those from the culture solutions of control or FO. The MO supplementation increased (p<0.0001-0.007) propionate proportion of culture solution but reduced butyrate proportion at 6 h (p<0.018) and 12 h (p<0.001) of incubations. Supplementation of MO or MO+FO increased (p<0.001) the proportions of $C_{18:2}$. The MO alone reduced (p<0.022-0.025) the proportion of c9,t11-CLA compared to FO in all incubation times. The FO supplementation increased the proportion of c9,t11-CLA. An additive effect of MO to FO in the production of c9,t11-CLA was observed at 6 h incubation. In vitro supplementation of monensin reduced hydrogenation of $C_{18^-}$UFAs while fish oil supplementation increased the production of CLA.

Purpose: The purpose of this study was to identify relationships between HbA1c (Glycosylated Hemoglobin), WHR (Waist hip ratio), WTR (Waist thigh ratio) and compliance in elderly diabetes mellitus patients aged 65 years or over. Method: We conducted a survey and measured HbA1c, WHR, WTR in a total of 180 elderly patients with diabetes from 5 May 2014 to 30 May 2014. The data were analyzed by t-test, ANOVA, and Pearson's Correlation Coefficient using the SPSS program. Results: There were no significant differences in diabetes-related characteristics for HbA1c, WHR and WTR. However, patients with a family history had low compliance scores (p=.004). Furthermore, patients who visited the hospital regularly had higher compliance scores than patients who visited hospital when they were sick (p<.001). Patients with diabetic complications had low treatment compliance scores (p=.001). In addition, WHR and WTR (r=0.47, p<.001). and WHR and compliance (r=0.15, p=.045) showed positive correlation. Conclusion: For elderly diabetes mellitus patients, diabetes-related characteristics and compliance were highly related, so it is necessary to improve compliance for managing diabetes mellitus.

Purpose: This study was to investigate relationships among distress, depression, anxiety, and spiritual needs of hospitalized patients with stomach cancer. Methods: The participants were 120 in-patients with stomach cancer for surgery or chemotherapy at C University in Seoul from December 2010 to February 2011. To measure emotional and spiritual states was used Distress management version 1 (National Comprehensive Cancer Network, NCCN), the Hospital anxiety and Depression Scale (HADS), and the Spiritual Needs Scale. The data were analyzed using SPSS 19.0, specifically descriptive statistics, t-test, ANOVA, Scheffe's test, and Pearson's correlation coefficients. Results: Distress showed positive correlations with anxiety (r=.49, p<.001), and depression (r=.44, p<.001). Anxiety showed positive correlations with depression (r=.59, p<.001). While, depression showed negative correlations with spiritual needs (r=-.25, p<.001). Conclusion: This study's findings show that hospitalized patients with stomach cancer experienced distress, anxiety, depression and high spiritual needs. Distress, anxiety, and depression of patients with stomach cancer were positively correlated with each other. While the level of depression was negatively correlated with the level of spiritual needs, indicating the higher the level of depression, the lower the spiritual needs. Therefore, nursing interventions for emotional and spiritual support need to be developed for stomach cancer patients.

The deformation behaviors of full annealed and T6 treated 6061, 7075 aluminum tubes are investigated at various temperature performing uniaxial tensile test. Full annealed Al 6061 and Al7075 tubes, and T6 treated Al7075 tube don't show sharp local necking with an elongation of 50% at $300^{\circ}C$. So it is expected that influenced by elevated tempterature. At $300^{\circ}C$ and strain rate of 0.001/s, many micro-cracks are observed in T6 treated Al 6061 tube, which is believed to be responsible for the decrease of total elongation.
