Purpose: The purpose of this study was to help enhance the quality of life for women with urinary incontinence. Self-esteem, urinary symptoms, peak pressure and duration in seconds for vaginal contraction after pelvic muscles exercise were examined. Method: One-group pretest-posttest design was employed participants were 27 married women from G city. The instrument for this study were : the self-esteem scale developed by Rosenberg(1965). the Urinary Symptom Questionnaire, a subjective measurement of urinary incontinence, developed by Jackson et al.(1996) and the Perineometer used as an objective measurement of peak pressure and duration in seconds. Result: 1. Self-esteem showed significant improvement after the exercise (t=-3.832, p= .001). 2. Comparison of results before the pelvic muscles exercise and after showed that there was a statistically significant difference for several urinary symptoms including enuresis (t=2.833, p=.009), frequency of incontinence (t=2.964, p= .006), incontinence volume (t=2.280, p= .031), incontinence before getting to the restroom (t=3.035, p= .006), incontinence with no reason or feeling (t= 3.051, p= 005) burning sensation (t= 2.132, p=.043), and a sense of residual urine (t=2.267 p=.032). The mean scores showed improvement in the urinary symptoms of management of incontinence (M=$0.04{\pm}0.22$), daily frequency of incontinence management (M=$0.13{\pm}0.85$), urinary control (M=$0.15{\pm}0.86$), running to the restroom (M=$0.15{\pm}0.60$) incontinence caused by coughing or physical activities (M=$0.19{\pm}0.57$) and hesitancy (M=$0.07{\pm}0.55$). Overall urinary symptoms decreased significantly (t =3.073. p= .007). 3. Peak pressure showed an increase from a mean of $24.26{\pm}16.20mmHg$ before the exercise to a mean of $28.63{\pm} 17.79mmHg$ after (t=-2.399, p=.024). Duration in seconds also increased from a mean of $6.00{\pm}4.95sec$ to $9.15{\pm}5.83sec$ (t=-4.400, p= 000). Conclusion: These findings suggest that pelvic muscle exercise serves to decrease urinary problems, improve self-esteem and increase peak pressure and duration in seconds.

This study was carried out to determine the effects of tomato powder (TP) on cooked pork patties during storage at $10{\pm}1^{\circ}C$ in the dark. The total phenolic and flavonoid contents of TP extract were 26.22 mg gallic acid/100 g and 3.52 mg quercetin/100 g, respectively. The extract of TP showed a potential antioxidant activity in the DPPH radical-scavenging assay ($EC_{50}=16.76{\mu}g/mL$). Pork patties were manufactured with 0.25% (T1), 0.5% (T2), 0.75% (T3) and 1.0% (T4) TP in a basic formula (C). The pH and volatile basic nitrogen (VBN) values of T2, T3 and T4 patties were lower (p<0.05) than the C patties during storage. Increased concentration of TP in meat patties decreased (p<0.05) the 2-thiobarbituric acid reactive substances (TBARS) and total plate count (TPC) values at d 7 of storage. Tomato treated-patties had lower (p<0.05) values for lightness ($L^*$), but higher (p<0.05) values for redness ($a^*$) and yellowness ($b^*$) at d 3 and 7 of storage compared with the C. In the case of sensory evaluation, the scores of colour, flavour and overall acceptability of T3 and T4 patties were higher (p<0.05) than those of the C patty after 3 or 7 days of storage.

Purpose: The purpose of this study was to investigate self-directed learning and critical thinking disposition which influence clinical competence in nursing students. Method: As a descriptive study, a total of 271 third year students were recruited from a nursing college in Daegu. A structured questionnaire was self-administered from June 7, 2011 to June 10, 2011. The data were analyzed using SPSS/WIN version 12. Results: In self-directed learning, there were significant differences in gender (t=2.26, p=.025), satisfaction of major (F=7.77, p=.001), and satisfaction of clinical experience (F=10.39, p<.001). Critical thinking disposition differed in gender (t=2.82, p=.005). Moreover gender (t=4.00, p<.001), satisfaction of achievement (F=6.50, p=.002), satisfaction of major (F=4.24, p=.015), and satisfaction of clinical experience (F=9.54, p<.001) differed with clinical competence. Clinical competence was positively related to self-directed learning (r=.45, p<.001) and critical thinking disposition (r=.51, p<.001). According to the result of multiple regression, critical thinking disposition (t=5.80, p<.001), satisfaction of achievement (t=3.33, p=.001), gender (t=2.93, p=.004) and self-directed learning (t=2.35, p=.019) were significant factors of clinical competence explaining 33.0% of the variances. Conclusion: Critical thinking disposition, satisfaction of clinical experience, gender and self-directed learning had a positive effect on clinical competence in nursing students. To enhance clinical competence for nursing students, it is necessary to develop self-learning teaching strategy and curriculum.

It has been proved that the union of two linear star-configurations in $\mathbb{P}^2$ of type $t{\times}s$ for $3{\leq}t{\leq}9$ and $3{\leq}t{\leq}s$ has generic Hilbert function. We extend the condition to $t$ = 10, so that it is true for $3{\leq}t{\leq}10$, which generalizes the result of [7].

의복을 착용하는데 있어 목적 상황에 부합하는 옷차림을 구성하는 것은 중요하다. 따라서 인공지능 기반의 다양한 패션 추천 시스템에서 의복 착용의 T.P.O(Time, Place, Occasion)를 고려하고 있다. 하지만 옷차림으로부터 직접 T.P.O를 추론하는 연구는 많지 않은데, 이는 문제 특성 상 다중 레이블 및 클래스 불균형 문제가 발생하여 모델 학습을 어렵게 하기 때문이다. 이에 본 연구에서는 label-distribution-aware margin(LDAM) loss를 도입하여 옷차림의 T.P.O를 추론할 수 있는 모델을 제안한다. 모델의 학습 및 평가를 위한 데이터셋은 패션 쇼핑몰로부터 수집되었고 이를 바탕으로 성능을 측정한 결과, 제안 모델은 비교 모델 대비 모든 T.P.O 클래스에서 균형잡힌 성능을 보여주는 것을 확인할 수 있었다.

This study was aimed to investigate the inhibitory effects of Porphyra dentata (P. dentata) extract on the adipogenesis of 3T3-L1 cells and evaluate its anti-obesity effect. The proliferation of 3T3-L1 cells and differentiation of adipocytes under treatment of P. dentata extract was examined by measuring the cell viability using alamarBlue assay and lipid droplets by Oil Red O staining. Results showed that P. dentata extract has no cytotoxicity effect and lipid droplets formation decreased in a concentration-dependent manner in 3T3-L1 cells. It has been confirmed that transcription factors affecting lipid accumulation and anti-adipogenic effects during cell differentiation are linked to P. dentata extract. We observed that P. dentata shows lowering the mRNA expression of peroxisome proliferator-activated receptor γ2 (PPARγ2), CCAAT/enhancer binding protein α (C/EBPα) that adipogenesis-associated key transcription factors and inhibiting adipogenesis in the early stages of differentiation. Treating the cells with P. dentata did not only suppressed PPARγ2 and C/EBPα but also significantly decreased the mRNA expression of adiponectin, Leptin, fatty acid synthase, adipocyte protein 2, and Acetyl-coA carboxylase 1. Overall, the P. dentata extract demonstrated inhibitory property in adipogenesis, which has a potential effect in anti-obesity in 3T3-L1 cells.

Hypothyroidism was induced in three age groups (8 months, 1 year and 2 years) of Black Bengal goats by administering thiourea subcutaneously for 30 days. From fourth day onwards the animals were observed to be in hypothyroid state. For 8 months age group, a control group of similar age was taken. For the 1 year and 2 years age groups there was no control group but the values obtained on the pre-treatment day were considered as control values. For confirming the establishment of hypothyroidism, peripheral plasma triiodothyronine $(T_3)$ and thyroxine $(T_4)$ were estimated in all the animals before and during the treatment period by radioimunoassay. In the thiourea treated 8 months age group the $T_3$ and $T_4$ levels were significantly (p<0.001) lower than those in the control group during the treatment period. In all the thiourea treated groups the $T_3$ and $T_4$ levels observed during the treatment period were significantly (p<0.01) lower than the pre-treatment levels. A nonsignificant loss in the body weight was observed in all the thiourea treated groups whereas there was a significant growth in the control group of animals. The study indicates that hypothyroidism has a negative effect on growth in goats.
