Objective: The study aimed to provide basic data for enhancing dental hygienists' practice of prevention for infections of dental hygienists by examining what factors there were in their preventing the infections in dental clinics. Method: The subjects of study were 168 dental hygienists who participated in continuing medical education of Incheon & Gyeonggi-do association and Seoul city association in October and November 2005. For the data analysis, an SPSS WIN 13.0 program was used and its significance level was 0.05. In terms of analysis methods, frequency analysis and technical statistics analysis were performed for general characteristics, ANOVA was performed for general traits, practice, medical environments for knowledge and practice analysis, correlation analysis was performed for the relation between knowledge & organization-related factors and practice, Chi-Square Tests were performed for the relation between general traits and educational experiences, T-test was performed for practice and knowledge according to the educational experiences for preventing infections and multiple regression analysis was performed for the factors that affect the practice for preventing infections. Result: knowledge showed statistically significant differences by age (F=4.895, p=0.003) and those with the education experiences in preventing infections had higher scores in practice of prevention for infections than those without them (t=3.315, p=0.001). The correlation between knowledge and practice was significant statistically (p<0.05), the factors related to organization showed significant correlation (p<0.01) and the higher the factors related to organizations, knowledge, education experiences, service career, the higher the practice for prevention of infections was ($R^2=0.32$). Conclusions: In order to enhance the dental hygienists' practice for the prevention of infections, it would be necessary to treat the contents of the infection prevention in educational curriculum at schools and enhance dental hygiene students' knowledge on the prevention of infection and to develop the programs, with which continuous education and PRS could be conducted through in-house education and continuing medical education of the hospital after school graduation and it has been believed that it would be the most important for dental hygienists to make efforts and interest in organizations actively so as to build up safe working environments.

To examine the cause of acute diarrheal disease in children and adolescents, 521 fecal samples underwent multiple-PCR for a period of two years, between March 2015 and February 20178, in the Jeju region of Korea. Based on the analysis of 179 positive samples, 102 samples were male (56.98%) and 77 were female (43.02%), and highest positive rates were shown in the age group of 3~4 years (51.96%) and 5~6 years (12.29%). When 209 cases (40.12%), including double infection were analyzed, there were 88 cases (16.89%) of norovirus-GII infection, 26 cases (4.99%) of Campylobacter spp. infection, 18 cases (3.45%) of rotavirus infection, 18 cases (3.45%) of Clostridium difficile Toxin B infection, 17 cases (3.26%) of adenovirus infection, 16 cases (3.07%) of Clostridium perfringens infection, 11 cases (2.11%) of astrovirus infection, 5 cases (0.96%) of Salmonella spp. infection, 3 cases (0.58%) of norovirus-GI, Yersinia spp. and Aeromonas spp. infections, and 1 case (0.19%) of verocytotoxin-producing E. coli infection. Based on a seasonal separation of early childhood, norovirus-GI and norovirus-GII mainly prevailed during the winter, when the temperature is low. Typical enteritis with an increased prevalence of rotavirus during the spring. Astrovirus prevailed between the months of April and October, when norovirus-GI, norovirus-GII, and rotavirus did not prevail. With increasing age, acute diarrheal disease was not only induced by a virus, but also by bacteria. Although a test for virus is an effective method when trying to identify the cause during early childhood by multiplex-PCR, it would be desirable to undergo tests for both virus and bacteria concurrently as age increases.

In emergency cases, such as the severe trauma involving the fracture of skull, spine, or cervical bone, from auto accident or a fall, and/or pneumothorax which can not be diagnosed exactly by the eye examination, it is necessary the radiological examination during transferring to the hospital for emergency care. The aim of this study was to design and evaluate the prototype of mobile medical image communication system based on CDMA 1X EVDO. The system consists of a laptop computer used as a transmit DICOM client, linked with cellular phone which support to the CDMA 1X EVDO communication service, and a receiving DICOM server installed in the hospital. The DR images were stored with DICOM format in the storage of transmit client. Those images were compressed into JPEG2000 format and transmitted from transmit client to the receiving server. All of those images were progressively transmitted to the receiving server and displayed on the server monitor. To evaluate the image quality, PSNR of compressed image was measured. Also, several field tests had been performed using commercial CDMA2000 1X-EVDO reverse link with the TCP/IP data segments. The test had been taken under several velocity of vehicle in seoul areas.

The objective of this study was to analyze patient satisfaction and perception of nutritional counseling services quality. A patient satisfaction and perception survey was conducted for 1,095 patients from 43 tertiary hospitals and 20 general hospitals. The number of returned questionnaires was 656 (response rate: 60.0%). Data from 633 questionnaires were analyzed after the questionnaires with unanswered items were excluded. Five domains were identified from the result of the factor analysis using the maximum likelihood and oblique rotation. The five domains were named empathy, responsiveness, tangibles, reliability, and skill and specialty. Patient perception mean score of nutritional counseling was 4.54/5.00. Patient satisfaction scores were significantly higher in empathy (P<0.001), responsiveness, and skill and specialty (P<0.01) with a college or graduate school education than in patients with a middle school education. There was no statistically significant difference between satisfaction scores in tertiary hospitals and those in general hospitals, but patients in capital hospitals reported significantly higher scores than their local counterparts in empathy, responsiveness, reliability, skill and specialty (P<0.001), and tangibles (P<0.05). In responsiveness, significantly higher (P<0.01) scores were observed in patients who received nutritional counseling only once compared to patients who received counseling two times. Patients perception of nutritional counseling services was significantly correlated with their satisfaction of five domains, reliability (r=0.721), responsiveness (r=0.697), empathy (r=0.690), skill and specialty (r=0.678), and tangibles (r=0.622).

Purpose : The system to refer terminally ill patients to palliative or hospice care which ultimately give them emotional, psychological, and social support hasn't been fully developed and organized yet in Korea. The controversies concerning the current referral system are being analyzed to present the improvements. Methods : The questionnaires were asked to be filled out by family members of the 76 patients by phone interview, who were referred from the Seoul National University Hospital between April, 2001 to March, 2002. They were referred to the 35 palliative and hospice care-giving institutes and hospitals which were given questionnaires by mail. Results : Of the 76 patient's family members, 47 family members accepted to answer the questionnaire. The first thing that influence to family to determine the referral of patient was solicitation of doctors or nurses (44%). And they were influenced by allowance for the other things such as convenience of patients (32%), convenience of caring family members (24%). In the course of determining of referred institutes, responders had considered at first their dwelling area, and then fame of institutes, the place which patent had wanted to spend last hours or which is suitable for patient's funeral service, and their financial condition. Thirty-eight the 47 responders answered that they had experienced difficulties in referral procedure. The worst among difficulties was unwanted discharge, and followings were lack of information about the referred institutes, concern about patient's suffering, resistance of patient and opposition of other family members, etc. Although they expressed dissatisfaction in referral procedure, most of them answered they had been satisfied with hospice care at referred institute after referral. Merits of referral which responders counted were patient's peace, caring family's comfort and reduced cost in order. Of the 35 referred institutes, 24 institutes' staffs responded mail questionnaires and sent to us in return. Except one responder, the rest approved the referral system and thought that referred patients had been satisfied with their hospice care. And they claimed that systemic support of the government is definitely necessary. The most difficult thing which responders experienced in care of referred patients was lack of information about patients. Besides, there were patient's financial problems, lack of understanding about their institutes of patients or family, and inconvenience of terminal cancer patient's pain control. Conclusion : The development and support of the organized referral system is needed to alleviate the troubles which patients, family members, and palliative or hospice institutes and hospitals have to face through the procedure of the referral.

This study aims to improve the satisfaction level of the patient who undergoes CT contrast examination by developing and applying pretreatment process system, which not only can reduce the side effects caused by the test but also can help carry out the test smoothly. The subjects were 214 patients who booked CT contrast examination from January 2014 to February 2014 but could not carry out their test on schedule. We analyzed the reasons for the delay and conducted follow-up survey on them. We analyzed the usefulness of pretreatment process system by contemplating and developing pretreatment process system and applying it to the patients for whom follow-up survey was conducted from January 2015 to February 2015. The number of outpatients who came to the hospital form January to February 2014 was 2,846 and the number of patients who could not undergo the test was 214, accounting for 7.52% of the total. The specific reason for the delay includes 214 cases of unknown creatinine 98 with 120 minutes of average delay time, 40 cases of creatinine over 1.3(19%) with 30minutes of average delay time, 34 cases of past contrast media side effect 6% with 40 minutes of average delay time and 25 cases of lack of pretreatment such as fasting, etc. 11% with 120minutes of average delay time. The number of CT scan has been increasing ever since the development of CT and the frequency of using the contrast media is expected to increase. If we can employ pretreatment process system in order to effectively control the side effect of contrast media and help the CT contrast examination to be smoothly conducted on schedule, I'm sure we could improve the quality of our medical service and increase our patients' satisfaction who come to our CT scan room.

The serving temperature control practices were assessed in 20 general hospital's dietetics utilizing centralized or decentralized tray assembly systems. The results of the study were summarized as follows : 1) All of the surveyed hospitals were utilizing conventional foodservice system. The number of dietary employees per bed was very low when comparing with that in America. Working hours of employees per week were approximately two times greater than those in America. 2) When comparing two tray assembly systems, dietary labor hours and costs in centralized system were less than those in decentralized system. 3) When comparing serving temperature practices between two tray assembly systems, the temperatures of meals utilizing centralized tray service were significantly lower than those in decentralized system, and only the steamed rice served in decentralized system was within the acceptable temperature range. 4) There was no significant difference in sensory acceptance scores marked by patients served by two different types of tray assembly systems. The serving temperature was significantly correlated to the patient's overall acceptability.

The purpose of this study was to compare the nurses' perceptions with the women's about the women's needs in premature labor and to find out how to accomplish effective nursing intervention for the women to cope with their crises in premature labor. The objects of this study consisted of 33 hospitalized mothers in post partum because of premature labor, who were delivered of new born, in four university hospitals, a general hospital and a lower general hospital which has a neonatal intensive care unit in Seoul during 17 days(Oct. 4, 1994 to Oct. 20, 1994) and 32 nurses who have worked at delivery rooms in the hospitals above for 6 months or more, accomplishing nursing intervention. The results of this investigation were as follows : 1) General characteristics of women : Their mean age was 29.4 years(SD 4.37) and the mean of their gestational periods 3 days over 34 weeks(SD 2.48). Most of them were the married(93.9%) and held high school degree or more(93.9%). And some of them were the deligious(68.7%), multiparae(59.4%) and had their jobs(21.2%). The also had hospitalized experience due to premature labor(51.5%), experienced in premature delivery(33.3%), the prental care(78.6%), cesearean section(63.6%), and pregnancies less than twice(62.5%). The most mothers were included in 34 weeks and a day to 37 weeks(60.6%). It was also confirmed that most of the sustaining presences in labor were their husbands(81.2%). 2) General characteristics of nurses : Their mean age was 27.6 years(SD 4.50), and their carrier with the service on the average 6 months over 3 years long(SD 3.63). Numbers of them were staff nurses(84.4%), maiden ladies(71.9%), graduated from junior colleges of nursing(71.9%), and had no experiences in delivery(78.1%).Besides, none of them had experiences in premature labor. 3) The whole mean of needs perceived by pregnant women was identified as 3.086 points and the degree of their perception was given much weight in order of interdependence need(3.14), self concept need(3.11), physical physiologic need(3.09), and role function need(2.74). So it was proved that they regarded interdependence need as being the most important need in crises caused premature labor. 4) The whole mean of needs felt by the nurses was 3.092 points and the degree of their feelings was given much weigh in order of physical physiologic need(3.22), self concept need(3.15), interdependence need(3.06) and role function need(2.75). So it was ascertained that they felt physical physiologic need the most important, differing from the women in it. 5) There were few differences on the degrees of the perceptions that the nurses and the women showed on each of the four parts. 6) On each part of the questionnaires, it was examined that the women felt the need for the fetus to be the most important generally while the nurses perceived the need with the women to be more important than that. 7) The primiparae(40.6%) felt role function need be more important than multiparae(59.4%) (p<0.05), and the women from universities and above(39.4%) perceived self concept need to be more important than those holding the high school degrees and below(60.6%). (p<0.05) 8) The nurses having experience in delivery(21.9%) perceived interdependence need and role function need to be more important than important than those having no experiences(78.1%). (p<0.05) So far most of the nurses have concentrated their efforts on nursing for safety for the women in premature labor hospitalized in delivery rooms. But the women are not satisfied with just it because of having perceived the need for the fetus more important above all. In nursing for the future, therefore, every nurse caring for the women should offer them all the informations that they will want for their fetuses to adapt them to the crises effectively, understanding such their needs and making most of honest and simple terms for them, I insist. Through this study, I'm sure that inquiring into the need of women in premature labor minetely will show the way of more effective nursing interventions in clinic. And I suggest that the various kinds of studies about the more objects be done for the generalization of the results of this study in the future.

Objectives : When a patient who attempts suicide visits the emergency room, it is important that the departments of emergency medicine, internal medicine, and psychiatry communicate with each other and prioritize treatment. This study was conducted to verify the effectiveness of the multidisciplinary emergency consultation system (ECS) for drug intoxicated patients. Methods : We retrospectively analyzed the data from medical records prior to the ECS, from July 2017 to May 2018, and after the ECS, from July 2018 to May 2019, to verify the effectiveness of the system. Results : After the ECS, admission to open wards was significantly higher than to the intensive care units (χ²=8.567, p=0.014). In addition, the proportion of consultations to the department of psychiatry among patients admitted to other departments tended to increase (χ²=4.202, p=0.053), and the time required for consultation response decreased (Z=-2.031, p=0.042). As a result of the consultation, the proportion of the patients who had been transferred to the department of psychiatry was increased (χ²=4.692, p=0.043), and the time spent to transfer tended to decrease (Z=-1.941, p=0.052). Conclusions : After implementing the ECS for drug intoxicated patients, unnecessary intensive care unit admissions, consultation response time, and the time spent to transfer were reduced, and the rate of consultation referrals and transfer rates increased. This means that the multidisciplinary consultation system rapidly provided essential medical services to patients at lower medical costs.
