Objectives: This study aimed to investigate the effects of auricular acupressure on fatigue and depression among patients undergoing chemotherapy for breast cancer. Methods: A nonequivalent control group nonsynchronized design was employed. Data were collected from December 2017 to May 2018, in the cancer center at a hospital located in B city. The experimental group received auricular acupressure four times a day, for 5 days, followed by a 2-day rest period. The control group received routine nursing care. The data were analyzed with independent t-tests, using the SPSS 21.0 program. Results: The level of fatigue and depression was lower in the experimental group as compared to that in the control group(t=5.29, p<.001; t=2.21, p=.038, respectively). However, depression scores increased post-intervention in the experimental group, as compared to the pre-intervention scores. Conclusions: The findings confirmed that auricular acupressure decreased fatigue however, depression scores increased post-intervention in the experimental group, as compared to the pre-intervention.

Recently, there has been growing interest in skyline queries. Most of works for skyline queries assume that the data do not have null value. However, when we input data through the Web or with other different tools, there exist incomplete data with null values. As a result, several skyline processing techniques for incomplete data have been proposed. However, available skyline query techniques for incomplete data do not consider the environments that coexist complete data and incomplete data since these techniques deal with the incomplete data only. In this paper, we propose a novel skyline group processing technique which evaluates skyline queries for the environments that coexist complete data and incomplete data. To do this, we introduce the top-k(g) skyline group query which searches g skyline groups with respect to the user's dimensional preference. In our experimental study, we show efficiency of our proposed technique.

Purpose: The purpose of this study was to identify the effect of auricular acupressure on pruritus and fatigue in hemodialysis patients. Methods: The study design was a randomized control group pre-post test. Initially, forty-four patients were randomly assigned to one of two groups. There was a loss of three participants assigned to the treatment group. The period of data collection was from December 2014 to March 2015. Both groups completed a pre-test. The treatment group received auricular acupressure once a week for ten weeks. Data were collected from the treatment group at two time periods: five weeks and ten weeks following initiation of the treatment protocol. Data were collected from the control group at week 5 and week 10. Data analysis was performed using IBM SPSS Statistics 21.0 program, specifically with the independent t-test and the Repeated Measures of ANOVA. Results: Auricular acupressure was effective in reducing pruritus (F=13.93, p<.001) and fatigue (F=18.33, p<.001). Conclusion: Auricular acupressure is a non-invasive simple method that can be used for the relief of symptoms reported by hemodialysis patients. This treatment modality could be used in several clinical areas.

Objectives : This study collected sleep information by wearable device in the Korean medicine Daejeon citizen cohort (KDCC). It was measured based on the sleep record information measured by wearing a Fitbit, and the possibility of clinical use was examined for compliance with objective sleep collection. Based on compliance, the possibility of clinical use was examined. Methods : After surveying personal information and PSQI(Pittsburgh Sleep Quality Index), sleep information was collected by Fitbit for 14 days. Compliance was measured based on sleep record information by Fitbit. Compliance was analyzed by sex, age, BMI(Body Mass Index), and sleep group(deep/poor). Results : The number of participants was 730, and the compliance was 94.3%, and the compliance group was 675(92.5%). The age of the participants varied from 30 to 60 years old, and the average age was 46±6.7 years. There were 218 males and 512 females. Young people have high compliance. Males are more compliance than females. As the BMI score decreased in the 30s, the compliance was higher. The underweight group in all age groups had 100 compliance. The underweight group was all female. The low compliance groups were that 30 years males (obesity level2), 50 years females (overweight group), and 50 years females (obesity level2). There was no significant difference in compliance between deep sleep group and poor sleep group. In deep sleep group, females showed higher compliance. In poor sleep group, males showed higher compliance. The average duration of Fitbit usage among participants was 20.1 days. The compliant group wore the device for an average of 21.3 days, while the non-compliant group wore it for only 5.2 days. Of the compliant group, 86.9% (73.8% of all participants) continued to wear the Fitbit after the recommended 14-day period, and 50.8% wore it for more than 20 days. Conclusions : This study showed the possibility of adaptation for wearing a Fitbit for collecting objective sleep information. It is judged that the compliance is high because it was worn for more than 13.2 days out of the 14 days required. It is considered meaningful because the compliance was measured based on the sleep information by Fitbit, not the questionnaire. As the data on objective sleep time is collected automatically, we believe that the burden on participants after the study period is not significant for a certain period. Compliance may be even higher for cohorts related to illnesses and with doctor's orders, rather than for the general population.

The purpose of this study was to find the effects of an educational program for primiparas on maternal confidence and continuity of breastfeeding. The subjects of this study were the healthy mothers, and the healthy infants whose weight was more than 2.500gm and gestational age was more than 37 weeks. The final targets were thirty seven mothers-19 of intervention group and 18 of control group. Data were collected from 15th of March to 3rd of September, 1999. To the intervention group, education on infant care and breast feeding were provided before discharge. And that, telephone advice was provided within one week after discharge, and at 2 months postpartum. And that, reeducation and counsel were provided at one month and three months postpartum by home-visiting care for the intervention group. For the control group. home visiting was also conducted only for data collection. Data were analyzed by chi-square test and t-test. The results were as follows: 1. The maternal confidence of the experimental group was higher than that of control group at one month postpartum. but the difference of confidence of these two groups were not significant at three months postpartum. 2. For both of experimental and control groups, maternal confidence significantly increased at three months postpartum than one month postpartum. 3. The rate of breastfeeding of the experimental group was higher than that of control group at one month and two months postpartum (p=.050, p=.049). But the difference was not significant at three months, although experimental group continued breastfeeding more(47.4%) than control group(27.8%). In conclusion, educational program for primiparas of this study was effective in the promotion of maternal confidence and breastfeeding.

The purpose of this study was to examine the effects of hand massage as a nursing intervention on the anxiety of the hysterectomy patients in immediately prior to surgery. The method of this study was Nonequivalent Control Group Non-Synchronized Design. The data were selected from at K university hospital in Pusan, and they consisted of Experimental group-25 patients, Control group -24 patients. The data were collected from Jan. 4 to Jan. 30 in 1999. The subjects′ self-reports of anxiety (measured by the Spielberger Trait-State anxiety Inventory and Visual Analogue Scale developed by Cline et al.) were recorded before and immediately after the intervention. The objective physiologic measures of blood pressure and pulse rate. The collected data were analysed by means of frequency, percentage, standard deviation, chi- square test, t-test, ANCOVA with SPSS program. The results of this study were as following; 1. Hypothesis 1: The 1st hypothesis that "There will be significant difference of the state anxiety level just before surgery in the experimental group and control group" was supported(P= .000). 2. Hypothesis 2: The 2nd hypothesis that "There will be significant difference of the visual analogue scale score just before surgery in the experimental group and control group"was supported(P= .000). 3. Hypothesis 3: The 3rd hypothesis that "There will be significant difference of the systolic and diastolic blood pressure level just before surgery in the experimental group and control group"was supported (P= .003, P= .041). 4. Hypothesis 4: The 4th hypothesis that "There will be significant difference of the pulse rate just before surgery in the experimental group and control group"was supported(P= .004). In conclusion, hand massage is a benefical nursing intervention that alleviates the psychological, physiological anxiety of the hysterectomy patients in immediately prior to surgery. therefore it is recomended to use the hand massage as a nursing intervention for patients undergoing anxiety. The results of this study appear promising, additional research is recomended to further the appropriate uses of hand massage in nursing practice for this and other patient population.

This study was conducted to investigate the anthropometric data, serum profiles, food intakes frequency, and nutrient intakes of women aged 30-49 years. The subjects were divided into two groups: drinking group and non-drinking group. For the study, we obtained data for analysis from the combined 2008-2015 Korean National Health and Nutrition Examination Survey (KNHANES). Height and weight were 159.2 cm and 58.1 kg in the drinking group as well as 158.1 cm and 57.7 kg in the non-drinking group, respectively. Obesity percentage in the two groups were 22.5% and 24.8%, respectively. HDL-cholesterol (P<0.001) and Vitamin D (P=0.0248) levels in the drinking group were significantly higher than those of the non-drinking group. In the drinking group, rates of hypertension, myocardial infarction, and diabetes were significantly lower than those of the non-drinking group. Food and nutrient intakes, including energy, water, protein, fat, retinol, thiamin, riboflavin, and niacin, in the drinking group were significantly higher than those of the non-drinking group. In the two groups, energy, water, fiber, calcium, and potassium intakes were low while Na intakes were extremely high considering KDRIs (Dietary Reference Intakes for Koreans). The mean adequacy ratio (MAR) in the two groups was not significant.
