  • The purpose of this study is to measure the tube voltage, the tube current/volume, exposure time and exposure dose of diagnostic X-ray unit in each doctor offices, hospitals and general hospitals for evaluating the performance of such device, to learn the method and technology of its measurement and to suggest its importance. Research subjects were total 30 X-ray units and divided into groups of 10 X-ray units each. The tube voltage, the tube current/volume, exposure time and exposure dose were measured using percentage average error, and then reproducibility of exposure dose was measured through calculating coefficient of variation. The results are like followings; The tube voltage correctness examination showed that incongruent devices among total 30 X-ray units were 5 devices (16.7%). The tube current correctness examination showed that incongruent X-ray units were 3 devices (10.0%). The tube current volume correctness examination showed that incongruent X-ray units were 4 devices (13.3%). Finally, according to exposure time correctness examination, incongruent X-ray units were 5 devices (16.7%) and according to reproducibility examination of exposure dose, incongruent X-ray units were 7 devices (23.3%). Above results showed serious problem in performance management based on management regulation of diagnostic X-ray unit; it means that regular checkout and safety management are required, and as doing so, patients will be able to receive good quality of medical service by the reduction of radiation exposure time, image quality administration, unnecessary retake and etc. Therefore, this study suggests that the performance of diagnostic X-ray units should be checked regularly.

  • Objective: The objective of this research was to develop a guideline for more effective use of physical restraint on patients in the intensive care unit and training the nurses on it and applying it on clinical practice to assess its effectiveness. Method: This research analyzed the before and after effect of the development of a guideline for physical restraint by dividing the category into nurse and patient. In the case of nurse, a comparison of knowledge and nursing service regarding the use of physical restraint from before the training on physical restraint guideline(Jan. 2011) and after the training on physical restraint guideline(Dec. 2011) was made. In the case of patient, a comparison of physical restraint usage rate and average usage time, the number of unplanned extubation cases were compared from before the use of physical restraint (Jan.~Apr. 2011) and after the use of physical restraint (Sep.~Dec. 2011) were made. Result: After the training on the physical restraint guideline, the knowledge of the nurse and the nursing practice showed notable improvement by (p<0.000) and (p<0.048) respectively and in patient, physical restraint usage rate and average time of usage decreased by (p<0.001) and (p<0.001) respectively. And despite the decrease in the number of cases in which the physical restraint was used, the number of unplanned extubation cases remained the same. Conclusion: Physical restraint guideline training and guideline usage can be stated to have brought out positive effect in both the nurse and patient. In order to maintain such positive effects, continuous training is necessary and continuous revaluation is necessary, regarding knowledge and nursing practices.

  • The Necessity and Purpose of the Study Recently the number of patients with chronic diseases and the aged patients is increasing steadily. Furthermore, due to the expansion of health insurance system, the number of patients hospitalized in the general hospital is increasing at a surprising speed. However, hospitals urge the early discharge of the patients for the efficiencies of hospital administration, and therefore, the number of patients who must be taken care of in their home is also increasing. Homecare nursing is one of the health care service for the patients at home who require continual attention and care, and now increasing attentions are given to it as one of the professional nursing fields. However, it was almost impossible to find a study on the actual experiences of the homecare nurses written by their own language in Korea, that it also posed a great difficulty in understanding their diverse experience. Considering these situation, this study will help understanding of them, and provide the fundamental data on their experiences for making policies to develop homecare nursing. Methods of Research Phenomenological research method was employed to analyze the lived experiences of homecare nurses fundamentally. Data collection Data were collected from August 1998 to December 1998 from ten homecare nurses who worked for patients under the homecare nursing setting as model cases designated by Seoul Nurses Association and who agreed to the purpose of this study after listening to and understanding the explanation completely. The in-depth interview was carried at the time which was convenient both for the researcher and participants for one or two hours, and recovered with the approval participants. The first interview covered diverse and broad areas like the situation of homecare nursing, and their feelings and thoughts over it, and in the second and third interviews, more specific questions are asked. Data Analysis For the phenomenological analysis, contents analysis was employed. The data collected from the participants were analyzed into the following procedures according to Van Manen 's phenomenological analysis. 1) Reserve the preconception of the researcher by restricting it inside parenthesis. 2) Make a thorough observation of the lived experiences by insight process. 3) Analyze the contents (Find out the repetitive factors) 4) Interpret the essence found. 5) State the meaning of the interpretation. Results and discussion 1. Fear and expectation for the first visit. (unfamiliarity, awkwardness, anxiety, shivering) 2. Mingle with the family (feeling friendly with the family, becoming like a family member) 3. Being proud of her own know-how (learning the know-how, organizing alternatives, building up confidence) 4. Pity for the poor. (criticizing the current government, feeling ashamed, feeling anger) 5. Difficulty of constructing cooperative system with physicians (strenuousness, frustration) 6. Helplessness due to the lack of support system (difficulty to get supplies, annoyance, embarrassment by institutional restraints) 7. Anxiousness for heavy traffic and parking (annoyance, hastiness) 8. Ethical conflicts (pity for the patients and family, skepticism about lengthening life maintenance) 9. Burden for the possible accident (pressure, anxiety, conflict, physical exhaustion) 10. Establishment of identity as a professional (fulfillment, worth, joy) 11. Being distressed at other's ignorance

  • The functions of urban park including health related benefit and climate adaptation and mitigation are expanding. However, in-depth research and discourse on the equitable distribution of expanded park function has been limited so far. Following research suggests Green Welfare concept to reflect distributive equity and multifunctionality in the process of urban park policy development and execution. This study developed park welfare indices to analyze disparities of neighborhood urban park(NUP) distribution viewed from green welfare by literature review. The findings analyzed through the Correlation Analysis and Cluster Analysis by SPSS 18.0. The results of the study are as follows. First, green welfare is defined as "to receive equitable benefits and participate in the delivery process of green services which are promoting health and securing safety from climate change risks for every citizen by life cycle regardless of socioeconomic status". Second, NUP per person in Seoul indicate meaningful differences by socioeconomic and environmental status of Seoul administrative districts. Park welfare indices correlated to NUP per person were shown population density(negative), percentage of individuals $aged{\geq}65$(positive), percentage of self-reliance of local finance(positive), flood and air pollution vulnerability by climate change(negative). Third, the cluster analysis identifies three significant clusters that indicate differences of park welfare level. Thus, it was found that NUP in Seoul from a green welfare perspective was provided disproportionately. Future urban park policy in Seoul was required equitable distribution of multifunctionality of park beyond quantitative expansion, and priority consideration should be given to park service consumer.

  • The current study aimed to analyze data conducting a survey with 211 females in Ulsan Gyeongnam province in order to understand what influence lifestyle types of female customers exert on eating-out behaviors from the perspective of eating-out motivation. So as to achieve research purpose, we conducted factor analysis, reliability analysis, t-test, ANOVA analysis, multiple regression analysis, correlation analysis and frequency analysis through SPSS 12.0 program. Findings of analyses indicated that items of lifestyle involve d 4 factors, and the item of eating out behaviors was extracted to be 1 factor. As a result of testing differences in lifestyle depending on residential areas, both type of chasing fashion and type of extroverted dependence have significant differences in variables, and both factors indicated that females living in Ulsan have higher mean values than those of females living in Gyeongnam. As a result of analyzing lifestyle depending on age, which was adopted in part, females at the ages of 31~40 had higher mean values than those in other ages in the type of chasing fashion, and females above the age of 51 had higher mean values than those in other ages in type of chasing health. As a result of lifestyle depending on academic backgrounds, university students or graduates had higher mean values than those in other academic backgrounds. For the influence of lifestyle types on eating-out behaviors depending on eating-out motivation, the type of chasing fashion, the type of purchasing the quality of life, and the type of chasing health were p<0.001, having significant effects.

  • The objective of this study was to research the health status of the elderly population and their perception and compliance to cook medicated juk. The results from this research will be used as basic data for medicated juk development. In addition, the purpose of this study was to find a way to popularize the juk and improve their usage as medicated juk in communal feeding and convalescent hospital for elderly. The study surveyed 300 elderly residents of age over 65, in Daejeon. The following data were collected: general characteristic, health status, perception of medicated juk, and preferred kind of juk for cooking. Moreover, the study researched the constraints in cooking the juk. Data were analyzed by SPSS Windows V. 18.0 and t-test verified the differences among the questions, according to frequency analysis of each item and characteristics of the aged. You might want to specify this characteristic. Within the surveyed elderly population, 80.6% had various existing diseases with circulatory diseases being the most prevalent with 68.9%. This emphasizes on the significance of proper diet, but this recognition is not put into practice. The survey also showed that as the individuals age, they tend to care less about the necessity of proper diet. Despite of this lack of perception, 84.5% of the elderly population responded positively to the question, "Would you like to have medicated juk for curing diseases, if such juk is available?" In addition, the elderly population was in favor of developing the juk that helps to prevent and cure diseases, and many were willing to cook them. The reasons behind their will to cook are arranged in the following order: higher efficacy in curing disease than regular juk, excellence in nutrition, and unavailability of the medicated juk in the stores that requires them to cook. The sources constraining the elderly population in cooking are arranged in the following order: not knowing how to cook the juk, lack of physical strength, financial burden, and lack of information order. Please clarify this part. Suggested change: not knowing what medicated juk is. Furthermore, the main obstacle in cooking the juk is lack of cooking technique, followed by inaccessibility to the ingredients and the financial burden to purchase the ingredients.

  • Salmonella enterica serovar Typhimurium (ST) is one of the most common serovars isolated from humans and animals. It has been suggested that ST infections in Koreans are largely due to the consumption of contaminated pork and beef. To investigate the genotypes, phage types, and antimicrobial resistance patterns for ST isolates of different origins, a total of 70 ST strains, including 19 isolates from humans, 44 isolates from pigs, and 6 isolates from cattle, were analyzed using pulsedfield gel electrophoresis (PFGE), phage typing, and antimicrobial susceptibility tests. Forty-three distinct PFGE patterns were generated from 70 ST isolates, which were grouped into 14 PFGE groups (from A to N) at the level of 75% similarity. The most prevalent group was the A (A1-A17 subtypes) group, encompassing 54.5% (38/70) of ST isolates. ST isolates from pigs and cattle mostly belong to groups A and L, whereas ST isolates from humans mostly belong to groups F and C. Antimicrobial susceptibility tests using 11 antimicrobial agents showed that resistance to tetracycline (TE) (81.4%) was highly prevalent, followed by streptomycin (S) (64.3%) and nalidixic acid (NA) (31.4%) resistance. A total of seventeen antimicrobial resistance patterns were observed. Only 8.6% of isolates, including a reference strain, were susceptible to all antimicrobial agents tested. The most prevalent resistance pattern was TE-S (37.1%), which was seen in 66.6% of bovine, 40.8% of swine and 21.1% of human isolates. Three ST isolates from humans (15.9%) showed resistance to 7-8 antimicrobials. The most predominant phage type (PT) was U302 (64.3%), followed by DT170 (10.0%). PFGE types did not coincide with antimicrobial resistance patterns and phage types; therefore, the combination of those types allowed for further differentiation between tested ST isolates.

  • Antibodies to Anaplasma phagocytophilum and Ehrlichia chaffeensis were detected by the immunofluorescent antibody (IFA) test in sera collected from cats, thoroughbred horses and Holstein cattle in Gwangju, Jeonju and Jeju Island of Korea. Two hundred fifty four sera (33 feral and pet cats, 92 grazing horses and 129 grazing cattle) were obtained from Republic of Korea. Antibodies to A. phagocytophilum (titer $\geq$ 80) were detected in 6 of the 33 feral and pet cats (18.2%), and 1 seropositive cat (3.0%) also had antibodies to E. chaffeensis. Only 1 of 129 (0.8%) cattle and 2 of 92 (2.2%) horses had antibodies to A. phagocytophilum. Antibodies to E. chaffeensis were not detected in either of these animals. This is the first report of serological evidence of A. phagocytophilum and E. chaffeensis from cats, cattle and horses in Korea. These rickettsial agents could have an important impact on human health or impact animal health with economic losses among industrial grazing animals in Korea.

  • The regional distributions and relative frequencies of endocrine cells were studied histochemically (Grimelius and Masson-Hamperl (M-H) silver methods) in the alimentary tract of the red-eared slider, Trachemys scripta elegans. Samples were taken from the esophagus, fundus, pylorus, duodenum, jejunum, ileum and large intestine. Argyrophil (Grimelius-positive) cells and argentaffin (M-H-positive) cells were found in the whole alimentary tract in this study. Spherical to spindle and/or oval to round-shaped argyrophil or argentaffin cells were located in the gastric glands of the stomach regions, in the basal portion of the epithelium of intestinal tract or the esophagus with variable frequencies. Argentaffin cells were more numerously detected in the whole alimentary tract compared with those of argyrophil cells in this study. Argyrophil cells were observed in the whole alimentary tract including the esophagus and the most predominant region was the rectum with moderate frequency. The relative frequency of these cells was rare in the esophagus, fundus, duodenum, jejunum and ileum, respectively and a few frequency in the pylorus. Argentaffin cells were also observed in the whole alimentary tract including the esophagus and the most numerously demonstrated region was the rectum with numerous frequency. They were observed with a few frequencies in the remaining regions of the alimentary tract except for the rectum, respectively. However, to know the exact type of the argyrophil cells and argentaffin cells that were observed in this study, more developmental methods such as immunohistochemistry were needed.

  • By studying the awareness level of students, for the need to protect personal information, and also by studying students' level of perception as to which information needs protection, this study aims to show that increased education is beneficial, and necessary, across all university majors. This increased education is necessary to improve information security, and increase the responsible sharing of private data which has many benefits, specifically in the Healthcare field. Utilizing student volunteers across multiple majors at a university in South Korea. These questionnaires measured the students' awareness of private information, their perception of private information and also the students' experience in receiving university level education regarding private information and the need for its protection. This study shows that, when compared to students in other fields, students in the field of public health had a higher level of awareness regarding the consequences of personal information disclosure for both public purposes and medical research. Within the parameters of this study, this outcome can be explained as the result of exposure to educational curriculum which contained information related to personal information protection. This increased education raised the student's awareness of which information is considered private, as well as, which information is valuable when responsibly shared. As a result, this study shows that an increase in education regarding information privacy, should be included in all university majors, and gives us evidence to support that this additional education is valuable to students at all levels and should be encouraged.
