Purpose: This study investigated the effects of the Seogeum therapy among college students with allergic rhinitis. Method: A non-equivalent control group pretest-posttest non-synchronized design was used. Intervention of Seogeum therapy has been performed from March 2 through March 31, 2017. Sixty college students diagnosed with allergic rhinitis from two different colleges in B and K cities were assigned to the experimental and control group. Data analysis were conducted using descriptive statistics, chi-square test, Fisher's exact test, and t-test. Results: There were significant differences in nose itching (t=4.89, p<.001), sneezing (t=6.26, p<.001), watery rhinorrhea (t= 4.09, p<.001), nasal congestion (t=2.36, p=.022), the percent of eosinophil (t=2.01, p=.049), perceived stress (t=2.05, p=.045), and allergic rhinitis related quality of life (t=4.33, p<.001) between the two groups. However, there were no significant differences in the percent of IgE (t=0.60, p=.553) and level of cortisol (t=0.53, p=.598). Conclusion: The results of this study indicates that the self-management of Seogeum therapy improved physical and psychological status of the college students with allergic rhinitis which ultimately improved their quality of life.

Objective: The experiments were carried out to measure the effect of multivitamin, acidifier and Azolla on growth performance, profitability and lipid profiles of blood of broiler chickens to produce safe and cost effective broilers. Methods: In experiment 1, 240 day-old Cobb-500 broiler chicks were fed diets; $D_1$ (control), $D_2$ ($D_1$ with 1 mL multivitamin/liter water), $D_3$ ($D_1$ with 1 mL acidifier/liter water), $D_4$ ($D_1$ with 1 mL multivitamin and 2 mL acidifier/liter water) having 3 replications in each, and 20 chicks/replication. In experiment 2, 150 day-old Cobb-500 broiler chicks were fed diets; $T_1$ (control), $T_2$ (5% Azolla in the diet), $T_3$ (7% Azolla in the diet) and $T_4$ ($T_1$ with 1 mL multivitamin and 1 mL acidifier/liter water) having 3 replications in each, and 20 chicks/replication in control, and 10 chicks/replication in the remaining dietary treatment groups for 35 days. Results: In experiment 1, the highest live weight was observed in $D_4$ (p<0.05), however, feed intake was statistically similar between diets (p>0.05). The lowest feed conversion ratio (FCR) (p<0.001) and mortality (p<0.05) were observed in $D_2$ followed by $D_4$, $D_1$, and $D_3$, respectively. There were no significant differences between diets for feed cost and net profit (p>0.05). However, evidently but not significantly, the highest net profit was obtained in $D_2$ followed by $D_4$, $D_1$, and $D_3$, respectively. In experiment 2, the highest live weight (p<0.05) and feed intake (p<0.001) were observed in $T_4$. Mortality (p<0.01), FCR (p<0.01), feed cost (p<0.05) and net profit (p<0.05) were significantly different among diets. Considering net profit, $T_2$ was the best performing dietary group followed by $T_3$, $T_1$, and $T_4$, respectively. The lowest lipid profiles were observed in $D_3$ followed by $D_1$, $D_4$, and $D_2$, respectively (p<0.05). In experiment 2, the lowest total cholesterol, TG, and the highest amount of high density lipoprotein were observed in $T_2$, followed by $T_3$, $T_1$, and $T_4$, respectively (p<0.05). Evidently but not significantly, low density lipoprotein was the highest in $T_2$ followed by $T_3$, $T_4$, and $T_1$, respectively (p>0.05). Conclusion: In conclusion, Azolla and acidifier reduced lipid profiles of broiler chickens. Considering net profit and lipid profiles, 5% Azolla may be the suitable dietary group for producing safe and profitable broilers. However, more studies are needed to confirm this study prior to suggesting using Azolla in the poultry industry.

This study examined the status on job satisfaction and job performance of Advanced Practice Nurses (APNs) in Korea. The data was obtained from the 2009 APNs' job satisfaction survey of 452 nurses who received the certificate of APN between 2005 and 2008 conducted by the Korean Accreditation Board of Nursing Education. ANOVA and t-test analyses using SPSS version 14.0 were performed. The average job satisfaction level of the APNs was 2.94 out of 5.00. APNs who were performing jobs as a certified APN had a higher level of job satisfaction (t=.23, p<.001), higher wages (t=2.23, p<.05), promotion in rank (t=2.56, p<.05), more professional job performance (t=10.52, p<.001), greatest trust in their bosses and coworkers (t=5.31, p<.001), and higher confidence in their job performance (t=5.07, p<.001) than those who were not. The government and the nursing community need to provide the APNs' with the appropriate supply and demand polices, as well as a proper incentive system and job improvement.

Objectives: The present study aimed to analyze the factors that could affect the health-promoting behaviors of North Korean adolescent refugees residing in South Korea. Methods: Questions about their sociodemographic variables, subjective health status, healthy living habits, and health-promoting behaviors were asked. Results: Statistically significant differences were found in religion (t=2.30, p<0.05), having family members in South Korea (t=2.02, p<0.05), and subjective health status (t=4.96, p<0.01). Scores on health-responsible behaviors were higher with higher age (t=2.90, p<0.01) and for subjects without family or friends (t=2.43, p<0.05). Higher physical-activity behaviors were observed in males (t=3.32, p<0.01), in those with better subjective health status (t=3.46, p<0.05) and lower body mas index (t=3.48, p<0.05), and in smokers (t=3.17, p<0.01). Nutritional behaviors were higher in those who followed a religion (t=2.17, p<0.05). Spiritual growth behaviors were higher in those who followed a religion (t=4.21, p<0.001), had no family in South Korea (t=2.04, p<0.05), and had higher subjective health status (t=5.74, p<0.01). Scores on interpersonal relationships and stress-management behaviors were higher for those with higher subjective health status. A multiple regression analysis showed greater effects on health-promoting behaviors when subjective health status was better. Older people and non-smokers exhibited more health-responsible behaviors, while more physical-activity behaviors and spiritual growth activities were observed when subjective health status was better. Interpersonal relationship behaviors had positive effects on those with good subjective heath status and on non-smokers. Conclusions: Based on the results of the current study, an alternative was suggested for promoting health in North Korean adolescent refugees.

This study was carried out to investigate the effect of lotus leaf extract on the physicochemical characteristics of ground pork stored at $4^{\circ}C$ for 10 days. Four types of ground pork were evaluated: ice water added (T0), 3% lotus leaf extract added (T1), 7% lotus leaf extract added (T2), and 10% lotus leaf extract added (T3). The pH was increased during storage, but decreased after 10 days of storage (p<0.05). The TBARS increased with a longer storage period (p<0.05), and those of T0, T1, T2 and T3 were 0.777, 0.244, 0.185, 0.182 mg MA/kg, respectively, after 10 days of storage. The VBN content of T0 and T1 increased with a longer storage period (p<0.05), but those of T2 and T3 were not significantly changed. In the case of surface color, the $L^*$ increased with a longer storage period, and that of T0 was the highest (p<0.05). The $a^*$ decreased with a longer storage period, and the $b^*$ was the highest after 1 day of storage (p<0.05). In the case of internal color, $L^*$ was not significantly changed, and $a^*$ was decreased with a longer storage period (p<0.05). The $b^*$ increased with a longer storage period (p<0.05). Water holding capacity increased with a longer storage period, and those of T2 and T3 were the highest (p<0.05). Cooking loss decreased with a longer storage period, and those of T0 and T1 were higher than those of T2 and T3 (p<0.05). Hardness and chewiness were not significantly different with a longer storage period, or among any samples.

Purpose: This study was conducted to explore relationships of postpartum depression with socio-demographic and clinical characteristics of preterm infants and mothers. Methods: Participants were the mothers of 80 premature infants admitted to neonatal intensive care units. Postpartum depression was measured using the Edinburg Postnatal Depression Scale (EPDS). Clinical characteristics were examined through the medical records. The physiological state for the infants was evaluated using the revised Neurobiologic Risk Score (NBRS). Data were analyzed using the t-test, ANOVA, and Pearson correlation coefficients. Results: Average for EPDS was $9.75{\pm}5.06$, and 30% of the participants were at high risk for postpartum depression. There were significant differences in postpartum depression according to mother's education level (F=3.493, p=.035), economic state (F=5.828, p=.004), multiple pregnancy (t=2.141, p=.037), chorioamnionitis (t=2.349, p=.021), oligohydramnios (t=-2.226, p=.029), broncho-pulmonary dysplasia (t=2.085, p=.040), germinal matrix hemorrhage (t=2.259, p=.027), and revised NBRS (t=-2.772, p=.007). There was a significant positive correlation between postpartum depression and number of health problem of infants (r=.252, p=.024) and revised NBRS (r=.316, p=.004). Conclusion: As 30% of the mothers with preterm infants were at high risk for postpartum depression, they require attention. When providing interventions, socioeconomic status as well as the physiological state of premature infants should be considered.

Emulsification sausages were prepared in 3 different ways: T1: fat added after ice, T2: fat added before ice, T3: all ingredients added together. Each sample was ground for 4.5 min by a silent cutter at $15^{\circ}C$ and emulsified batters were stuffed into fibrous casing and then cooked for 40 min at $78^{\circ}C$ to determine the effect of the order of ingredient addition on the qualities of emulsion type sausage. The pH of T1 sausage was significantly higher, whereas the pH of T3 was significantly lower compared with the other samples(p<0.05). The shear force was significantly higher in T1 sausage, however the hardness and gumminess were significantly lower in T1 sausage compared with other two types(p<0.05). With regard to sensory evaluation, the relative amounts of flavor can be summarized as T2>T1>T3, and the color was significantly higher in T1 and T2 compared with T3(p<0.05). There was no significant difference among the test sausages with regard to aroma, juiciness, tenderness and overall acceptability(p>0.05). There were no significant differences in free moisture, water holding capacity(WHC), meat color and texture properties such as brittleness, cohesiveness, springiness and chewiness. As a result of this study, the sausage were much for sausage prepared by adding the fat after the ice(T1) than the other sausage samples in which fat was added after ice to make emulsion type sausages.

This study was carried out to investigate the effects of inuloprebiotics (INPs), an alternative antibacterial growth promotor, from Jerusalem artichoke extract (Helianthus tuberosus L.) on egg production and quality in Hyline brown laying hens. The hens were divided randomly into four treatment groups and housed in individual cages for 10 weeks: a control group (0 ppm INP) (T1), 450 ppm (T2), 600 ppm (T3), and 750 ppm (T4). Egg production, egg weight, Haugh unit, eggshell thickness, and breaking strength were significantly higher in all of the INP-treated groups compared with the control (p<0.05). Egg cholesterol was highest in the T1 group and decreased with INP addition from 15.04 to 17.98% (p<0.05). Compared with the T1 group, triglycerides in the blood and in total cholesterol decreased significantly in groups T2, T3, and T4 by 21.71-24.07% and 27.17-30.36%, respectively (p<0.05). The growth of cecum Bifidobacterium and Lactobacillus was stimulated in groups T2, T3, and T4 compared with T1, whereas the growth of Escherichia and Salmonella was clearly inhibited (p<0.05). The results suggest that the addition of 450 ppm INP to the diet of laying hens can improve egg production and egg quality.

Kidney bean was used in the brewing of Takju. The Takju formed varied the percentage of kidney bean used; that is, 0%(only rice) in $T_{-1}$, 100%(only kidney bean) in $T_{-2}$, 90% in $T_{-3}$, 80% in $T_{-4}$, 70% in $T_{-5}$, 60% in $T_{-6}$, and 50% in $T_{-7}$. We determined the total sugar, pH, reducing sugar, alcohol production, acidity, and DPPH free radical scavenging activity of Takju. The acidic value of $T_{-1}$ was above that of $T_{-6}$, and the pH of $T_{-2}$ was above that of $T_{-1}$. Both satisfy the food code parameters (namely, below 0.5 in acidity, 3.8~4.7 in pH). The alcohol production of $T_{-1}$ was above that of $T_{-2}$. For 2 days of fermentation, the reducing sugar of $T_{-1}$ totaled 2, down from 4.96%. After fermentation, there was not much difference from 4 to 12 days. The antioxidative effect of $T_{-1}$ proved to be much better than those of the other. Thus, we can be seen that these results thus indicate that the role of kidney bean added to Takju show good antioxidative activity. From the result of sensory test, we also concluded that the taste of Takju kidney bean is very similar to that of Takju with rice.

Let $\mathbb{N}_0$ be the set of non-negative integers, and let P(n, l) denote the set of all weak compositions of n with l parts, i.e., $P(n,l)=\{(x_1,x_2,{\cdots},x_l){\in}\mathbb{N}^l_0\;:\;x_1+x_2+{\cdots}+x_l=n\}$. For any element $u=(u_1,u_2,{\cdots},u_l){\in}P(n,l)$, denote its ith-coordinate by u(i), i.e., $u(i)=u_i$. A family $A{\subseteq}P(n,l)$ is said to be t-intersecting if ${\mid}\{i:u(i)=v(i)\}{\mid}{\geq}t$ for all $u,v{\epsilon}A$. A family $A{\subseteq}P(n,l)$ is said to be trivially t-intersecting if there is a t-set T of $[l]=\{1,2,{\cdots},l\}$ and elements $y_s{\in}\mathbb{N}_0(s{\in}T)$ such that $A=\{u{\in}P(n,l):u(j)=yj\;for\;all\;j{\in}T\}$. We prove that given any positive integers l, t with $l{\geq}2t+3$, there exists a constant $n_0(l,t)$ depending only on l and t, such that for all $n{\geq}n_0(l,t)$, if $A{\subseteq}P(n,l)$ is non-trivially t-intersecting, then $${\mid}A{\mid}{\leq}(^{n+l-t-l}_{l-t-1})-(^{n-1}_{l-t-1})+t$$. Moreover, equality holds if and only if there is a t-set T of [l] such that $$A=\bigcup_{s{\in}[l]{\backslash}T}\;A_s{\cup}\{q_i:i{\in}T\}$$, where $$A_s=\{u{\in}P(n,l):u(j)=0\;for\;all\;j{\in}T\;and\;u(s)=0\}$$ and $$q_i{\in}P(n,l)\;with\;q_i(j)=0\;fo\;all\;j{\in}[l]{\backslash}\{i\}\;and\;q_i(i)=n$$.
