Background: Nosocomial infection control is one of important means to assure the quality of medical care in the hospital, however, it has been neglected by most of the hospital personnels. Of nosocomial infections, urinary tract infection is the highest incidence, which is related to the indwelling catheter. It is, therefore, necessary to pay primary attention to the patients with the indwelling catheter in intensive care unit in order to control nosocomial Infection and to improve the quality of medical care in the hospital. Methods : The subjects of this study were patients with indwelling catheter who were admitted to the ICU of Pusan Paik Hospital from March 1994 to May 1995. The author calculated UTI rate among the subjects through the cultivation of the urine, identified the related factors of the UTI through brain storming of study team and head nurses working at ICU, and analized the effectiveness of the proposed approaches through comparing the infection rates of before and after activities. Results : The major activities carried out by the study team were to conduct in-service education programs for the staffs working at ICU about the importance of the nosocomial infection control in QA, and nursing intervention to reduce the UTI rate among the patients with indwelling catether. 1. The major nursing interventions that the study team had implemented were as follows ; 1) Drainage system was changed from partial open system to completely closed system. 2) Bladder irrigation which was routinely practised in all patients stopped among the noninfected patients. 3) Bladder irrigation set was changed to the disposable one. 4) Catheter was inserted under the anesthesia for patients to be operated. 5) Male patient receiving wrapped with gauze after perineal care was not wrapped. 6) Clamp which had not been before was newly attached to drainage tube. 7) Urine bag which had been packed into a lot of pieces was done into each piece. 8) The interval of change of indwelling catheter had regularly been four weeks, however it was used continously until it worked well. 9) Catheter was attached well at the defined site. 10) Paper towel was used instead of cotton towel. 11) Mats at the entrance were removed and cleansing of wards was enhanced. 2. The UTI rate by month was 34.4% in maximum and 9.8% in minimum during the period of this study, however it had gradually decreased. After 6 months from initiating infection control activities, the trend of rates was relatively stable. It was identified that UTI rate was different by season 12.5% in winter and 27.2% in summer. 3. Utilization rate of indwelling catheter was maintained at under 50%, but it was increased above 57% from April 1995. 4. The number of bladder irrigation sets used per day was 33.3 sets in maximum and 2.8 sets in minimum. The number used per day were also remarkably deceased. Conclusion : It was found that a program to control UTI could contribute to nosocomial infection control, and it was, in turn, a mean to assure the quality of medical care in the hospital. The nursing interventions which this study team had implemented were effective in the reduce of UTI rates.

This study investigated the quality of rice noodles containing different amounts of mesangi (Capsosiphon fulvescens) powder. The noodles were prepared with ratios of 1.9, 3.8, and 5.7% (w/w) of mesangi powder based on the flour weight. The noodles containing mesangi powder had lower moisture contents compared to the control, while amounts of ash were higher than in the control. For the cooking properties of the noodles, weight, volume, and turbidity were significantly higher in the mesangi rice noodles than the control (p<0.0001). The mesangi rice noodles had lower L- and a- values than the control, and these values decreased with increasing amounts of mesangi powder while the b- value increased. Texture profile analysis of the cooked noodles showed significantly higher levels of hardness (p<0.0001) and adhesiveness (p<0.05) in the mesangi rice noodles compared to the control, while cohesiveness (p<0.05), springiness (p<0.05), and gumminess (p<0.0001) values were lower than those of the control. However, the values for hardness, adhesiveness, cohesiveness, and springiness were not significantly different among the mesangi rice noodle groups. The pH of the rice noodles gradually decreased over 8 days of storage time. The 3.8% mesangi rice noodles had lower total and fungus plate counts than the other noodles during 15${\sim}$24 days of storage. However, the 3.8% masangi noodles showed the highest overall acceptability score(p<0.05).

Purpose: The purpose of this study was to investigate dental technicians' awareness of infections and to enhance their interest and commitment towards infection prevention. Methods: A self-reported questionnaire survey was conducted among dental technicians. Total of 195 responses were used for analysis. A cross-tabulation analysis was used to compare dental technicians' awareness of infections according to their levels of education on infection prevention (α=0.05). Results: Dental technicians were educated on infection prevention (40.5%). Most participants received infection prevention education from school (29.8%). Dental laboratories had an infection control guideline (34.9%). Dental technicians were not aware of infection risks at their workplaces or believed that they were not at risk of infections at their workplaces (59.3%). Conclusion: Dental technicians must be consistently educated on infection prevention and control through systematic education at school and wider promotion through media. Research is needed to economically and efficiently improve equipment used by dental technicians and to protect them from infectious diseases. A budget for infection prevention must also be determined. Institutional measures such as providing support for dental technicians at the policy level and developing a basic infection prevention manual are necessary. Solving these issues not only protects dental technicians from infections but also allows them to provide high-quality medical services.

The quality characteristics of tofu added Ligularia fischeri powder (LFP) were investigated. The proximate composition of LFP used was as follows: moisture, 7.7%; crude protein, 12.0%; crude lipid, 5.9%; crude ash, 14.1%; and carbohydrate, 60.3%. The yield of tofu added LFP increased with the addition of LFP. However, there was a significant decrease in pH (from $6.03{\pm}0.11$ in the control to $5.78{\pm}0.11$ when 0.4% LFP was added) and a significant increase (from $2.60{\pm}0.01$ in the control to $2.85{\pm}0.10$ when 0.4% LFP was added) in total acidity. In addition, the L, a, and b values of tofu decreased with the increasing addition of LFP. In terms of textural properties, the hardness, cohesiveness, and brittleness increased, whereas springiness decreased, with the increasing addition of LFP. In the sensory evaluation, the overall preference for tofu added 0.3% LFP was the highest. According to the results, the addition of LFP positively affects the overall sensory evaluation of tofu, and 0.3% is the optimal level for addition.

Purpose: The purpose of this study was to identify effects of a self-management program on symptom and functional status, health perception, and quality of life(QOL) of patients with CHF. Methods: Patients with CHF as defined through clinical judgment using the Framingham criteria and EF<50% were enrolled in the study (experimental: 21, control: 20). The symptom focused self-management program consisted of coping behaviors for symptoms including dyspnea, chest discomfort/pain, dizziness, ankle edema, and basic self-management including medications, diets, activity, lifestyle changes. Experimental group received an educational booklet after survey, and periodic telephone follow-up by a trained nurse. Data were collected the 3rd day after admission and at 1 month, 3 months, and 6 months after discharge using questionnaires. Results: Significant differences were found in the presence of symptoms, health perception, and QOL between groups during follow-up. Although no significant difference was found in functional status, the experimental group reported better functional status than the control group. Conclusion: By facilitating self-management of CHF using tailored interventions including education programs and telephone monitoring, it is expected that patients will be able to monitor their symptoms routinely, adhere to therapeutic regimen, and have a better QOL.

The purpose of this study was to investigate the effect of music listening, autogenic training, and music-assisted autogenic training on the quality of life, physiological and psychological relaxation responses, and daily living in a population of migraine patients. Forty migraine patients, ranging 20 to 60 years, were referred to the researcher by their physicians and participated in the study. A convenience control-group pretest-posttest design was employed. The participants were randomly assigned to one of four groups: music listening (ML), autogenic training (AT), music-assisted autogenic training (MAT), or a control group participants, with n = 10 participants per group. The participants in experimental groups received four 30-minute sessions with an assigned treatment, once a week during a 4-week experiment period. The participants in the control group continued their regular medical treatment as prescribed by the doctor without receiving any other relaxation treatment. However, they were still aware of the research and their responsibilities for the study. The Migraine Assessment (MIDAS) and Migraine-Specific Quality of Life (MSQOL) questionnaire were used to investigate a migraine patients' quality of life collected before and after the 4-week experiment for all subjects. The physiological and psychological relaxation responses of migraine patients were measured by relaxation levels and forehead temperature recorded before and after each treatment session for the participants in three treatment conditions. The effect of the relaxation treatments on daily living of migraine patients was examined through the frequency and intensity of migraine headaches, and the amount of medication taken for migraine headaches during the 4-week experiment as recorded in participants' diary for all participants. The results found significant differences from pre- to posttest on the MIDAS, MSQOL, and relaxation levels while no significant was found among the groups. The analysis of forehead temperature showed no significant difference from pre- to posttest and among the groups. A one-way ANOVA was performed on the frequency, intensity, and amount of medication taken for migraine headaches during the 4-week experiment period. While results yielded no significant difference among the groups, the data indicate that the participants in the three treatment groups reported fewer migraine headaches, lower degrees of headache intensity, and less medication taken for migraine headaches than participants in the control group. A conclusion drawn from this study is that music listening itself as a relaxation treatment, or as an adjunct to other relaxation techniques can be effective in the treatment of migraine headaches.

Methods : Subject of the research were total 71 elementary and middle school teachers in J province who had not experience to have cardiopulmonary resuscitation. They were divided into experimental group of 35 participants who practiced cardiopulmonary resuscitation from both right and left direction of mannequin on Dec. 27, 2009 and control group of 36 participants who performed cardiopulmonary resuscitation from only right direction of mannequin on Dec. 28, 2009. Collected data were analyzed by SPSS/PC+(version 14.0). Results : 1. There was no statistically significant difference by sex among general characteristics of the subjects. 2. According to the quality of chest compression performed from the right direction of mannequin, experimental group showed better results in proper depth (time), insufficient depth (time), too lowered compression position (time) and inexact position (time) than control group(p<.05). In the quality of chest compression from the left side of mannequin, experimental group performed better results in proper depth (time), insufficient depth (time), inexact compression position (time) and mean chest compression depth(mm) than control group(p<.05) and also in more left-centered compression position (time) than control group(p<.001). 3. The quality of chest compression by experimental group, the right side of mannequin was superior in proper depth (time) to the left side of mannequin (p<.001) and showed better results in insufficient depth (time) and chest compression/recoil rate (p<.05). According to the quality of chest compression by control group, the right side of mannequin showed superior results in proper depth (time), insufficient depth (time), too left-centered compression position (time) and mean chest compression depth (mm) (p<.05) to the left side of mannequin. Conclusion : The group having practice from both right and left sides of mannequin was superior in the quality of chest compression to the group having practice from only right side of mannequin. How to practice cardiopulmonary resuscitation from both right and left sides of mannequin can be recommended and practice from left side of mannequin is also useful.

This research aims to identify the determinants of e-government satisfaction in Hanoi, Vietnam, and assess their impact. To collect data, we conducted an online questionnaire with citizens living in Hanoi in a time span of five weeks. We received 1,107 responses, divided into three groups: unaware, known, but not used, and used e-government. After leveraging past studies on satisfaction in different contexts, we arrived at six external variables that are of particular relevance to e-government satisfaction (i.e., efficiency, trust, reliability, convenience, citizen support, and transparency) as well as four control variables (i.e., age, gender, education level, and Internet frequency). We then applied both SPSS 22 and STATA 2016 to process and analyze the collected data and found that, while almost all external variables are statistically significant, all four control variables are not. Apart from convenience and trust, four factors - efficiency, reliability, citizens support, transparency - are important measures of system quality, information quality, service quality and relative benefits of e-government, which in turn positively and significantly impact citizens' satisfaction with the online public services. Furthermore, the efficiency variable has the most influence on customer satisfaction, and the level of impact on the dependent variable decreases in the following order: citizen support, reliability and transparency.

Background: The aim of this study was to determine the effectiveness of self-efficacy promoting pulmonary rehabilitation in patients with chronic obstructive pulmonary disease (COPD). Methods: thirty six patients, with clinically stable COPD were randomly assigned: 18 to a rehabilitation group and another 18 as a control group, The subjects participated in a the self-efficacy promoting pulmonary rehabilitation program for 8 weeks. This program consisted of education, breathing retraining, exercise training, relaxation and counseling. The control group received education only. The outcome variables were self-efficacy, dyspnea, exercise endurance, pulmonary function, and quality of life. Dyspnea was measured using the modified Borg scale. Exercise endurance was measured by the six minute walking distance. The quality of life was measured by the quality of life index for pulmonary disease patients. Results: In the rehabilitation group after performing the self-efficacy promoting pulmonary rehabilitation program, the self-efficacy score, exercise endurance, and quality of life score were higher than the control group (p=0.007, p=0.038, and p=0.039, respectively). and the exertional dyspnea score was significantly lower than controls(p=0.045). However, the dyspnea score and FEV1 were similar after performing the self-efficacy promoting pulmonary rehabilitation program. Conclusion: The self-efficacy promoting pulmonary rehabilitation program is effective to in improve self-efficacy, exertional dyspnea, exercise endurance and quality of life in patients with COPD.
