Background: Patients with colorectal cancer are usually treated with chemotherapy, which reduces the number of blood cells, especially white blood cells, and consequently increases the risk of infections. Some research studies have reported that aromatherapy massage affects the immune system and improves immune function by, for example, increasing the numbers of natural killer cells and peripheral blood lymphocytes. However, there has been no report of any study which provided good evidence as to whether aromatherapy with Thai massage could improve the immune system in patients with colorectal cancer. The objectives of this study were to determine whether the use of aromatherapy with light Thai massage in patients with colorectal cancer, who have received chemotherapy, can result in improvement of the cellular immunity and reduce the severity of the common symptoms of side effects. Materials and Methods: Sixty-six patients with colorectal cancer in Phichit Hospital, Thailand, were enrolled in a single-blind, randomised-controlled trial. The intervention consisted of three massage sessions with ginger and coconut oil over a 1-week period. The control group received standard supportive care only. Assessments were conducted at pre-assessment and at the end of one week of massage or standard care. Changes from pre-assessment to the end of treatment were measured in terms of white blood cells, neutrophils, lymphocytes, CD4 and CD8 cells and the CD4/CD8 ratio and also the severity of self-rated symptom scores. Results: The main finding was that after adjusting for pre-assessment values the mean lymphocyte count at the post-assessment was significantly higher (P=0.04) in the treatment group than in the controls. The size of this difference suggested that aromatherapy with Thai massage could boost lymphocyte numbers by 11%. The secondary outcomes were that at the post assessment the symptom severity scores for fatigue, presenting symptom, pain and stress were significantly lower in the massage group than in the standard care controls. Conclusions: Aromatherapy with light Thai massage can be beneficial for the immune systems of cancer patients who are undergoing chemotherapy by increasing the number of lymphocytes and can help to reduce the severity of common symptoms.

Objectives: Previous large-scale cohort studies conducted in Korea have found a positive association between diabetes mellitus (DM) and colorectal cancer (CRC) in men only, in contrast to studies of other populations that have found significant associations in both men and women. Methods: A total of 1070 CRC cases and 2775 controls were recruited from the National Cancer Center, Korea between August 2010 and June 2013. Self-reported DM history and the duration of DM were compared between cases and controls. Odds ratios (ORs) and 95% confidence intervals (CIs) were calculated by binary and polytomous logistic regression models. Results: DM was associated with an elevated risk of CRC in both men (OR, 1.47; 95% CI, 1.13 to 1.90) and women (OR, 1.92; 95% CI, 1.24 to 2.98). This association remained when we controlled for age, body mass index, alcohol consumption, and physical activity level. In sub-site analyses, DM was associated with distal colon cancer risk in both men (multivariate OR, 2.04; 95% CI, 1.39 to 3.00) and women (multivariate ORs, 1.99; 95% CI, 1.05 to 3.79), while DM was only associated with rectal cancer risk in women (multivariate OR, 2.05; 95% CI, 1.10 to 3.82). No significant association was found between DM and proximal colon cancer risk in either men (multivariate OR, 1.45; 95% CI, 0.88 to 2.41) or women (multivariate OR, 1.79; 95% CI, 0.78 to 4.08). Conclusions: Overall, DM was associated with an increased risk of CRC in Koreans. However, potential over-estimation of the ORs should be considered due to potential biases from the case-control design.

This study aims to grasp the influence of a college student's academic emotions and the ability of interpersonal relations according to gender on the SNS addiction tendency. Data were collected through a self-reported structured questionnaire from 130 college students using convenient sampling methods from September 1 to October 31, 2015. The research result showed that in the case of male college students, only the ability of interpersonal relations (${\beta}=-.41$, p=.009) was understood as a variable with an influence on the SNS addiction tendency, having approximately 16% power of explanation (F=2.26, p=.049) after controlling for age, daily average duration of using SNS, subjectively-perceived level of dependence on SNS, and one's own level of using SNS. In the case of female college students, it was understood that the daily average duration of using SNS (${\beta}=.42$, p<.001) and positive academic emotions(${\beta}=.27$, p=.010) were variables having an influence on the SNS addiction tendency, having approximately 28% power of explanation (F=5.19, p<.001). Accordingly, to solve the psycho-social health problems related to male and female students' SNS addiction based on this research, it might be helpful for planning a program by taking into account the differences between the related variables according to gender.

Objectives: To find evidence that sleep is necessary for normal brain function, thus indicating that declines in both sleep quality and quantity are related to worse performance of many daily tasks and deteriorated physical functions. The present study investigates the relationships of balance control and reaction time with sleep quality. Methods: 58 healthy (male 20, female 38) volunteers with informed consent participated in this study. The Self-reported Pittsburgh Sleep Quality Index (PSQI) was used to evaluate sleep quality and relevant factors, and the subjects were divided into groups A (PSQI < 5) and B ($PSQI{\geq}5$) based on this index. Static balance control and reaction time to visual stimuli were conducted to assess their relationship with sleep quality. Results: Group B exhibited excessive daytime sleepiness significantly more often compared to group A. Static balance control did not markedly change relative to sleep quality, but reaction time and error to visual stimuli were significantly increased in group B compared to group A. Conclusion: These findings indicate that a decline in sleep quality can result in delayed reactions, as well as decreased accuracy of these reactions. They also suggest that low sleep quality may be associated with changes in physical functions, including balance control through reduced selective attention.

This study examined the change in the students' perception of infection after school education. A self-reported questionnaire was filled out by 300 dental hygiene students in Kangwon from December 3 to December 4, 2016. The contents of the questionnaire included the general characteristics (5 items), infection-related selection (2 items), infection control recognition (5 items), and infection control behavior (10 items). The data were analyzed by frequency analysis, t-test, one way ANOVA, Chi-square test, and hierarchical multiple regression analysis using SPSS 24.0. The Cronbach's Alpha was 0.941 and 0.658, respectively. The school year and hospital practice experience had some influence on the change in infection recognition. A total of 127 students (62.6%) who had experience in practicing in hospitals knew more about antibodies. Hand washing was the highest in personal protection, followed by masks. The selection of the infectious control education method showed that the practical training class was high irrespective of the hospital practice experience, and the perceptions of patient-related infections were the greatest explanatory factor in perception after education.

The aim of this study was to identify the influencing factors and the relationships between the learning ability and stress according to the character type in nursing college students. A total of 209 subjects were selected by convenient sampling. The data was collected using a self-reported questionnaire from November 2 to 20, 2012. The differences in the character type, learning ability and stress according to the general characteristics were as follows. The character type was significantly different according to grade (F=6.551, p<.036). In addition, the learning ability was significantly different according to the grade (F=7.059, p<.001), religion (F=4.651, p<.001), school record (F=7.667, p<.001), economic status (F=7.700, p<.000) and methods of reducing stress (F=2.531, p<.030). Stress was significantly different according to the grade (F=7.414, p<.001), school record (F=4.776, p<.009) and cohabitation (F=9.989, p<.000). A negative correlation was observed between the character type and learning ability, and between learning ability and stress. 8.4% of the variance was observed in character type A, which was explained by the learning ability and stress. These findings may be useful for understanding the learning ability of nursing college students and developing more specific programs regarding personality and stress control.

The purpose of this study was to investigate psychological separation, depression and antidepressive coping behaviors and to examine the relationship between psychological separation, and depression in Korean university students. The subjects were 131 students who were in 4 university in Chungcheong-do, Korea. The data were collected through self reported structured questionnaire using the psychological separation index, beck depression inventory and antidepressive coping behaviors instrument. The level of depression was classified into; not depressed, 54.2%; mildly depressed, 22.9%; moderately depressed, 16.8%; severely depressed, 6.1%. Among antidepressive coping behaviors, cognitive activity-oriented behaviors was the one with highest percentage(30.8%). Depression was negatively related to functional independence, attitudinal independence, emotional independence from father and conflictual independence from mother. And depression was positively related to conflictual independence from father. These results suggest that it is necessary to develop nursing intervention to strengthen psychological separation form parents and to be able to help desirable antidepressive coping behaviors for the psychological health of university students.

Recently rapid environmental changes due to desertification and industrialization in China make a threat to Korea, especially during Asian Dust Event (ADE). This study was aimed to compare symptoms and behaviors related to ADE between Korea and China. We conducted questionnaires on self-reported symptoms and behaviors before and during ADE. Korean and Chinese subjects were grouped into children, adults, and elderly by nation (n=791). Statistical analyses were performed by $X^2$-test, Fisher's exact test, t-test and chow's test for comparing differences between Korean and Chinese. We estimated the odds ratio for perceived symptoms during ADE by preventive behavior, using Generalized Estimation Equation (GEE). The study indicated that there were significant differences between symptoms in Korea and those in China such as cold, cough, and sore throat, especially in elderly. Preventive behaviors such as avoiding outdoor activity and wearing sunglasses were more often performed in China than Korea. However wearing mask was more often performed in Korea than China. After adjusting for age, sex, educational level, and smoking status, the odds ratio (OR) of dry cough symptom in Korea was significantly decreased by closing the windows and wearing a mask during ADE. In China, the OR of dry cough symptom was decreased by wearing a mask and avoiding outdoor activity. We found that China which had higher performance of preventive behavior showed lower prevalence of symptoms during ADE than Korea. Also preventive behaviors could affects prevalence of symptoms during ADE. This results suggest that preventive behavior. could reduce symptoms during ADE and there are needed for. more attentions to reduce a threat of ADE.

This study was aimed at examining the pattern of dietary fat intake of 120 university female students living in Kongju city in order to provide baseic data for establishing the dietary grideline of desirable fat intake. The subjects were divided into three groups according to living arrangenment ; family home(FH), or dormitory(DM), or self-boarding house(SB). Fat consumption of subjects was surveyed by two-day food records, and profiles of fatty acid and cholesterol taken were calculated based upon the data reported their contents of foods. The result was that mean daily fat intake was 42$\pm$2g for FH, 48$\pm$4g for DM and 41$\pm$3g for SB. The calorie intake by fat was 20.8, 21.5, and 20.4% respectively. The ratio of P/M/S was 1.3/1.7/1 for FH, 1.3/1.6/1 for DM and 1, .5/1.5/1 for SB. And the ratio of n-6/n-3 fatty acid was 5.2/1 for FH, 8.3/1 for DM and 7.2/1 for SB. Daily cholesterol intake was 208$\pm$20mg for FH, 223$\pm$29mg for DM and 251$\pm$27mg for SB. In addition, intake of n-3 fatty acid was 1.2$\pm$0.2g for FH, 0.9$\pm$0.1g for DM and 1.2$\pm$0.2g for DB. Considering the food source of fatty acids, saturated fatty acid and monounsaturated fatty acid were taken primarily from animal foods, especially milk and milk products, and n-6 polyunsaturated fatty acid was taken from vegetable oils and fats. As a major source of n-3 fatty acid, linolenic acid was obtained through vegetable oils and fats, and eicosapentaenoic acid and docosahexaenoic acid were provided by fishes and their products. There patterns of fatty acid intakes did not differ according to living arrangement. The above results showed that intakes of fat and cholesterol, and ratios of P/M/S and n-6/n-3 fatty acid were overall desirable in all groups. However, intake of n-3 fatty acid was low in all groups. Therefore, consumption of perilla oil, legumes and fishes as a source of n-3 fatty acid should be increased by substituting other food source which provide fats and oils because calorie intake by fat was enough in these subject.
