Objective: To compare short- and long-term dentoalveolar, skeletal, and rotational changes evaluated by Björk's structural method of superimposition between children with Class II malocclusion treated by functional appliances and untreated matched controls. Methods: Seventy-nine prepubertal or pubertal children (mean age, 11.57 ± 1.40 years) with Class II malocclusion were included. Thirty-four children were treated using an activator with a high-pull headgear (Z-activator), while 28 were treated using an activator without a headgear (E-activator). Seventeen untreated children were included as controls. Lateral cephalograms were obtained before treatment (T1), after functional appliance treatment (T2), and after retention in the postpubertal phase (T3). Changes from T1 to T2 and T1 to T3 were compared between the treated groups and control group using multiple linear regression analysis. Results: Relative to the findings in the control group at T2, the sagittal jaw relationship (subspinale-nasion-pogonion, p < 0.001), maxillary prognathism (sella-nasion-subspinale, p < 0.05), and condylar growth (p < 0.001) exhibited significant improvements in the Z- and E-activator groups, which also showed a significantly increased maxillary incisor retraction (p < 0.001) and decreased overjet (p < 0.001). Only the E-activator group exhibited significant backward rotation of the maxilla at T2 (p < 0.01). The improvements in the sagittal jaw relationship (p < 0.01) and dental relationship (p < 0.001) remained significant at T3. Condylar growth and jaw rotations were not significant at T3. Conclusions: Functional appliance treatment in children with Class II malocclusion can significantly improve the sagittal jaw relationship and dental relationships in the long term.

This study was conducted to investigate the influence of the mixed application of chemical fertilizer (CF) and liquid swine manure (LSM) on the agronomic characteristics, dry matter yield, amino acids, minerals, and free sugars in cultivating Sorghum ${\times}$ Sudangrass hybrid (SSH) on paddy soil. The field experiment was designed in a randomized block design with three replications and consisted of CF 100% (C), CF 70% + LSM 30% (T1), CF 50% + LSM 50% (T2), CF 30% + LSM 70% (T3), and LSM 100% treatment (T4). The application of LSM was based solely on the nitrogen. Plant length, leaf length, leaf width and number of leaf were significantly higher in T4 (p<0.05), but stem diameter did not show significant differences among treatments. Stem hardness increased significantly (p<0.05) as the LSM application rate decreased, but sugar degree decreased significantly (p<0.05) as the LSM application rate decreased. Fresh yield, dry matter yield and TDN yield were the highest in T4, whereas the lowest in T2 (p<0.05). Crude protein, crude fat and crude ash were the highest in C, T4 and T2, respectively (p<0.05). However, NDF and ADF did not show significant difference among treatments. Crude fiber decreased significantly (p<0.05) as the LSM application rate increased. The total mineral content was decreased significantly (p<0.05) as the LSM application rate increased. Total amino acid content was higher in the order of T1> C> T3> T4> T2 (p<0.05). Free sugar content increased significantly (p<0.05) as the LSM application rate increased. The analysis of all the above results suggests that the application of liquid swine manure is very effective, considering the yield performance and the content of sugar degree and free sugar. In addition, liquid swine manure may be possible to grow Sorghum ${\times}$ Sudangrass hybrid without chemical fertilizer.

The objective of the present study was to investigate the effects of growth performance, chemical composition and meat quality parameters by the addition of fermented persimmon shell diets (FPSD). The experimental animals were ninety-six Berkshires. The pigs were allotted at 8 per pen in front-open building with three replicate pens per treatment. Until $61{\pm}1kg$ live weight at 140 days, the animals were fed growing diet, after which, experimental samples were fixed at 0, 3, 5 and 7% FPSD as C, T1, T2 and T3 in the finishing diets. Pigs of $103{\pm}1kg$ live weight were slaughtered by electrical stunning. In growth performance, ADG increased more (p<0.05) in T2 than C and T1. ADFI (kg/day) was higher (p<0.05) in T2 than in other groups. Feed conversion ratio was lower (p<0.05) in T2 than in other groups. On longissimus dorsi muscle (LM), the content of moisture was lower (p<0.05) in T3 than in other treatments. Crude fat increased (p<0.05) by addition of FPSD. pH at 24 h ($pH_{24}$) decreased more (p<0.05) in T2 and T3 than C and T1 by addition of FPSD. WHC decreased (p<0.05) by addition of FPSD. In meat, Hunter $L^*$ and $a^*$ were lower (p<0.05) in C than in other treatments. Hunter $b^*$ was higher (p<0.05) in T3 than in other treatments. In back-fat, Hunter $L^*$ was higher (p<0.05) in C than in other treatments. Hunter $a^*$ was not different in C and T1 but increased (p<0.05) in treatments by addition of FPSD. Hunter $b^*$ increased (p<0.05) by addition of FPSD. In sensory evaluation scores, for fresh meat, the value of meat color was higher (p<0.05) in T2 and T3 than in C and T1. The value of marbling was lower (p<0.05) in C than in other treatments. The value of drip loss was higher (p<0.05) in C than in other treatments and was lower (p<0.05) in T2 and T3 than in other treatments. The results of cooked meat, the value of tenderness was not different in C and T1 but increased (p<0.05) in other treatments. The value of flavor was significantly higher (p<0.05) in T2 and T3 than in C and T1. The value of overall acceptability was increased (p<0.05) by addition of FPSD. Hence we can conclude that addition of FPSD affected growth performance and meat quality parameters, in particular, it improved crude fat, hunter $L^*$ and $b^*$, and sensory evaluation on pork and was also seen to affect $pH_{24}$ and WHC. FPSD can be used for improvement of meat quality parameters.

Purpose: This study aims to identify the relationship between marital intimacy, depression, and menopausal symptoms, and to provide basic data for the health promotion of middle-aged women. Methods: A sample of 231 middle-aged women was recruited from four cities in Korea. The survey was conducted with participants using self-reported questionnaire from July 9 to November 11, 2011. The data were analyzed using descriptive statistics, t-test, ANOVA, and Correlation Analysis. Results: There were differences of marital intimacy scores that were statistically significant in educational background (F=6.88, p=.001), religion (t=3.96, p<.001), own job (F=4.47, p=.012), own salary (F=3.01, p=.019), spouse's salary (F=6.72, p<.001), ownership of residence (t=4.00, p<.001), leisure with spouse (t=-5.05, p<.001), current treatment of disease (t=2.22, p=.027), and current disease (t=2.53, p=.012). Marital intimacy was correlated with depression (r=-0.61, p<.01) and menopausal symptoms (r=-0.39, p<.01). Conclusion: Marital intimacy in middle-aged women is closely related to both depression and menopausal symptoms. The nursing program that improves marital intimacy will be useful to promote the health of middle-aged women.

The objective of this study was to determine the effects of milk supplemented with Sel-Plex on thyroid hormones, rectal temperature, plasma glucose and cholesterol concentrations, and body weight in suckling calves. Ten Holstein suckling male calves of approximately 1 month of age were selected and randomly allocated to one of two groups and fed either unsupplemented milk (control) or milk supplemented with 0.3 mg/kg DM Se from Sel-Plex (treated). The animals received treated milk and free choice starter for two months. Dry matter intake for each individual animal was recorded daily throughout the study. The calves were weighed and blood samples were taken weekly. Plasma concentrations of triiodothyronine ($T_{3}$), thyroxin ($T_{4}$) and $T_{3}$-Uptake were determined using radioimmunoassay kits. Plasma cholesterol and glucose concentrations were determined by enzymatic-colorimetric methods. Rectal temperature was recorded at blood sampling time. During the experiment, ambient temperature and relative humidity were recorded at the time of blood sampling and every four hours. Treatment significantly (p<0.01) affected the concentration of $T_{3}$, free $T_{3}$ index ($FT_{3}I$) and ratio of $T_{3}$:$T_{4}$ in plasma. The plasma concentrations of $T_{3}$ in treated calves were 33% higher than in the control. The plasma concentrations of $T_{4}$ (p<0.05), glucose (p<0.01) and cholesterol (p<0.01) were decreased in the treated group. Calves fed Sel-Plex had higher rectal temperature (p<0.01). Plasma free $T_{4}$ index (FT4I) did not differ significantly between the two groups. An increase in body weight was observed (p<0.09) in the treated group. The results indicated that milk fortified with Sel-Plex could increase tissue conversion of $T_{4}$ to $T_{3}$ and therefore improve thermometabolism in suckling calves.

This study was carried out to determine the effects of olive oil prepared tomato powder (OPTP) used as lycopene source on fresh pork patties. OPTP was not added (0%; C), or was added at 0.25% (T1), 0.5% (T2), 0.75% (T3) and 1.0% (T4) in a basic pork patty formula and patties were stored for 7 days at $5^{\circ}C$. pH values of T3 and T4 were lower (p<0.05) than those of control until storage day 3. However, pH values of treated samples were dramatically increased (p<0.05) after 7 d of storage. Cooking loss values of treatments were lower (p<0.05) than those of control at day 1 of storage. Thiobarbituric acid reacting substances values were lower (p<0.05) in all treatments than in untreated samples during storage. All treated samples had lower values (p<0.05) for lightness ($L^*$) but significantly higher values (p<0.05) for redness ($a^*$) and yellowness ($b^*$) than the untreated samples during storage. Total plate counts of T4 were lower (p<0.05) than others during storage. In sensory evaluation, the scores of color, aroma and overall acceptability in T3 and T4 scored higher (p<0.05) than those of control at days 1 and 3 of storage, however, statistical significance was not found (p>0.05) among the samples after 7 days of storage. In conclusion, tomato powder-treated groups were significantly higher in redness ($a^*$) and yellowness ($b^*$), and lipid oxidation was inhibited, as compared with control during storage. Therefore, as a natural additive, tomato powder could be used to extend the self-life of meat products, providing the consumer with food containing natural additives, which might be seen more healthful than those of synthetic origin.
