Purpose: This study was conducted in order to prove related practice factors of handwashing with soap and its practices by students in South Korea. Method: The subjects consisted of 700 students. Data were collected in Sep 2013 and were analyzed using descriptive statistics, chi-square test, and logistic regression analysis. Results: Total number of handwashing times was 7.5 per day. 65.1% of the students used soap and most of the students washed their hands for 20 seconds(31.1%). Self-evaluation, awareness of effect for prevention of infectious disease, and need for handwashing education were positive, but evaluation of toilet environment was negative. Most of the students washed their hands for 21 seconds(%), and methods of handwashing were not appropriate. Level of awareness was over 85% in most items. Practice differed significantly according to locations, pattern of school, self-evaluation, awareness of effect for prevention of infectious disease, need for education handwashing, and toilet environment. Conclusion: These findings indicate that the students learned methods of handwashing for its practice in South Korea, and they were considered as general characteristics of handwashing from students. In addition, results mentioned above will be reflected in development of educational programs for improvement of handwashing efficiency.

In this study, a survey was carried out on 200 23-year old unmarried men and women attending j university in j city from October 4 to October 7, 2011 to figure out pre-parents' perception of parental role and view of children, and put forward the necessity of pre-parent education by providing opportunities for pre-parent education. The results are summarized as follows. First, the perception of general parenting and parental role showed that 'parenting' is the highest, following by 'parental role'. For women, nuclear families and large families, who feel much necessity of pre-parent education in the academic liberal arts, the perception of general parenting, parental role and parenting by sub-factors was positive. Second, the perception of general view of children showed that 'children plan' is the highest, followed by 'pregnancy and birth.' For those surveyed, who have a plan for marriage and children plan or feel much necessity of pre-parent education in the academic liberal arts, the perception of general view of children, children plan by sub-factors, and pregnancy and birth was relatively positive. As for findings stated above, for pre-parents in their 20s~30s, women' perception of parental role and view of children was more positive than men'. And nuclear families' or large families' perception was more positive than single parent families'. These findings confirm there is a difference between parental role and view of children according to growth environments of pre-parents in social realities that the low birth rate is growing.

Objectives : In the present study, anti-metastatic properties of the methanol extract of L. obtusiloba (MLO) were evaluated. Methods : To determine the effect of MLO on cancer metastasis, we checked matrix metalloproteinase-2 (MMP-2) and matrix metalloproteinase-9 (MMP-9) activities and expressions in B16F10 melanoma cells. In addition, we performed cell migration assay as well as invasion assay using Matrigel. Finally, we used an in vivo lung metastasis model to confirm the anti-metastatic activity of MLO. Results : 1. MLO showed potent inhibitory effects on MMP-2 and MMP-9 activities and expressions via down-regulation of activation of NF-${\kappa}B$ in B16F10 melanoma cells. 2. Melanoma cell migration and invasion were down-regulated by MLO treatment. 3. Not only in vitro model, but MLO also significantly suppressed lung metastasis in vivo. Conclusions : The present results indicate that MLO has strong inhibitory effect on cancer metastasis. Therefore, L. obtusiloba could be a valuable anti-metastatic agent.

Objectives: The purpose of this pilot study was to examine the effects of a mindfulness-based Body-Mind Intervention Program using marine resources on the improvement of quality of sleep, mood symptoms, and cognitive function in Korean female emotional labor workers. Methods: Twelve female workers who experienced excess emotional labor participated at the training camp program for five days in Danghangpo-ocean park, Goseung-gun, Gyeongnam Province in South Korea. Participant sleep quality, mood symptoms, and cognitive functioning before, after, and 1.5 months later were evaluated and analyzed. Results: After participating in the marine resource program, participants reported significantly decreased sleep latency. Global sleep quality, cognitive functions (attention, flexibility, and inhibition control), and mood states, including depression, tension, anger, fatigue, were also improved. These effects were generally maintained after 1. 5 months (PSQI t = 2.63, p = 0.02 ; HAM-D t = 5.92, p < 0.001). Conclusion: A Body-Mind Intervention Program using marine resources was effective in relaxing emotion-related tension and improving cognitive function. To advance this pilot study, it is necessary to carry out further research to investigate the use of marine resources in mental health interventions.

The purpose of this study was to investigate the relationship amongst emotional labor, communication competence, resilience, and clinical nursing performance of university hospital nurses, and to identify the influencing factors on job performance of clinical nurses who work at two university hospitals. The data was collected using questionnaires from 216 nurses in February 2016. Data was analyzed using one-way ANOVA, Pearson correlation, and stepwise multiple regression using IBM SPSS 22. There were differences in communication competence (F=3.679, p=.003), resilience (F=7.909, p<.003), and nursing performance (F=2.331, p=.044) correlates with the frequency of leisure activity. The significant relationships were found among age (r=.242, p<.001), years of service (r=.278, p<.001), emotional labor (r=.211, p=.002), communication competence (r=.585, p<.001), and resilience (r=.431, p<.001) with nursing performance in university hospital nurses. The result of the stepwise multiple regression indicates that communication competence and years of service predict 40.9% (F=75.356, p<.001) in nursing performance of university hospital nurses. The most powerful predictor was communication competence (${\beta}=.581$, p<.001), followed by years of service (${\beta}=.268$, p<.001). In conclusion, to enhance nursing performance for university hospital nurses, it is necessary to develop and utilize educational programs that enhance the communication competence and to develop strategies to support leisure activities for university hospital nurses.

Three beef steers fitted with permanent cannulae in the rumen and duodenum were used to determine the effects of protein supply from soyhulls (SH) and wheat bran (WB) on ruminal metabolism, blood metabolites, nitrogen metabolism, nutrient digestion and concentrations of soluble non-ammonia nitrogen (SNAN) in ruminal (RD) and omasal digesta (OD). In a 3${\times}$3 Latin square design, steers were offered rice straw and concentrates formulated either without (control) or with two brans to increase crude protein (CP) level (9 vs. 11% dietary DM for control and bran-based diets, respectively). The brans used were SH and WB that had similar CP contents but different ruminal CP degradability (52 vs. 80% CP for SH and WB, respectively) for evaluating the effects of protein degradability. Ruminal ammonia concentrations were higher for bran diets (p<0.01) than for the control, and for WB (p<0.001) compared to the SH diet. Similarly, microbial nitrogen and blood urea nitrogen were significantly increased (p<0.05) by bran and WB diets, respectively. Retained nitrogen tended (p<0.082) to be increased by SH compared with the WB diet. Intestinal and total tract CP digestion was enhanced by bran diets. In addition, bran diets tended (p<0.085) to increase intestinal starch digestion. Concentrations of SNAN fractions in RD and OD were higher (p<0.05) for bran diets than for the control, and for WB than for the SH diet. More rumendegraded protein supply resulting from a higher level and degradability of CP released from SH and WB enhanced ruminal microbial nitrogen synthesis and ruminal protein degradation. Thus, free amino acids, peptides and soluble proteins from microbial cells as well as degraded dietary protein may have contributed to increased SNAN concentrations in the rumen and, consequently, the omasum. These results indicate that protein supply from SH and WB, having a low level of protein (13 and 16%, respectively), could affect ruminal metabolism and nutrient digestion if inclusion level is relatively high (>20%).

Objectives To initiate and develop a treatment guideline in multidisciplinary approaches for related professions who are either working and/or living with children and adolescents with neurodevelopmental disorders who show behavioral problems. Methods To collect and reflect opinions from multiple professions who assumedly have different interventions or mediations on behavioral problems, a self-report survey and Focus Group Interview (FGI) were conducted for a group of child and adolescent psychiatrists, behavioral therapists, special education teachers, social welfare workers, and caregivers. Results According to a self-report survey and FGI results from multiple professional groups, aggressive behavior is the mostly common behavioral problem necessitating urgent interventions. However, both mainly used intervention strategies and effective treatment methods were different depending on professional backgrounds, such as pharmacological treatment, parent training, and behavior therapy, even though they shared an importance of improving communication skills. In addition, there was a common understanding of necessity to include parent training in a guideline. Lastly the data suggested lack of proper treatment facilities, qualified behavior therapists, and lack of standardized treatment guideline in the field needed to be improved for a quality of current therapeutic services. Conclusion It is supported that several subjects should be included in the guidelines, such as how to deal with aggressive behavior, parent training, and biological aspects of neurodevelopmental disorders. Also, it is expected that publishing the guideline would be helpful to above multiple professions as it is investigated that there are lack of treatment facility and qualified behavioral therapists compared to need at the moment.

The purpose of this study was to investigate the effect of family characteristics of the baby boomer generation on the level of their later life preparation. This study randomly sampled a birth cohort between 1955 and 1963 consisting of participants living in Seoul, South Korea with a spouse and a child/children. This study investigated a total of 455 subjects from March 2 to March 20, 2016. The study findings are summarized as follows. This study analyzed the characteristics of baby boomers' family relationships and their effects on their later life preparation. It was found that 55.4% of the subjects had at least 2 children, and 44.6% had 1 child. Concerning their children's marital status, 33.8% had married children and 66.2% had unmarried children. The level of their children's support was found at 2.82 points (standard deviation [SD] = .64), which is slightly higher than the mean value of 2.5. The spouse satisfaction among the subjects was found to be 3.59 (.79) which is higher than the mean value of 3. The general status of later life preparation was 2.70 (SD = .44), which is lower than the mean value of 3. In the sub-dimension, the level of social preparation was 2.98 points (SD = .61); the level of economic preparation was 2.60 (SD = .64); and the level of physical preparation was 2.53 (SD = .45). All the values were lower than the mean value of 3. The overall status of later life preparation of the subjects in this study was low. The physical preparation level was particularly low. To analyze the factors that affect baby boomers' later life preparation, a hierarchical regression analysis was implemented. As a result, a significant effect was found in specific factors, such as spouse satisfaction (${\beta}$ = .32, p < .001), age (${\beta}$ = .26, p < .001), number of children (${\beta}$ = -.18, p <.001), health status (${\beta}$ = .18, p < .001), gender (${\beta}$ = -.11, p < .05), household income (${\beta}$ = .10, p < .05), and children's marital status (${\beta}$ = .10, p < .05). That is, the higher the spousal satisfaction, the older the age, and the lower the number of children, the higher the levels of later life preparation. Further, a higher level of later life preparation was observed in women, those with higher household incomes, and those with married children.

Chronic kidney disease (CKD) occurs in more than 15% of the dogs over 10 years of age and causes irreversible renal function deterioration. Therefore, it is important to diagnose CKD early and treat the disease properly. The purpose of this study aimed to to evaluate the clinical utility of urine albumin/creatinine ratio (ACR) using POC (point-of-care) device as an early detection urinary biomarker in CKD dogs and to confirm the correlation between ACR and other known CKD biomarkers. Urine and serum samples were obtained from 50 healthy dogs and 50 dogs with CKD. Serum blood urea nitrogen (BUN), creatinine, and symmetric dimethylarginine (SDMA) concentrations, and urine protein creatinine ratio (UPC) were measured. Urine specific gravity (USG) was evaluated using refractometer, and ACR was measured using an i-SENS A1Care analyzer. The ACR values of dogs with CKD were significantly different from those of healthy dogs (p < 0.001), as with other renal biomarkers. ACR showed significant differences between healthy dogs and dogs with CKD at every IRIS stage (p < 0.005), whereas no significant differences were observed between dogs with CKD IRIS stage I and healthy dogs with UPC. There are significant positive correlation between ACR and BUN (r = 0.611, p < 0.001), creatinine (r = 0.788, p < 0.001), SDMA (r = 0.747, p < 0.001), and UPC (r = 0.784, p < 0.001), and significant negative correlation between ACR and USG (r = -0.700, p < 0.001). In receiver operator characteristic curve analysis, the area under the curve (AUC) was 0.982 (95% CI 0.963-1.000, p < 0.001), with an optimal cut-off value of 64.20 mg/g (94% sensitivity and 94% specificity). Thus, ACR is a useful urinary biomarker for the early diagnosis of proteinuria in CKD and combined use of ACR and other renal biomarkers may be helpful for early diagnosis and prevention of CKD in dogs.
