This study examined the variables that affect whether consumers change broadband internet services by examining their past experiences and intention to switch carriers by targeting consumers who have switched broadband internet service providers. Among adult consumers who intended to switch broadband providers, 341 people who had experience were subject to logistic regression analysis using SPSS for Windows ver. 17.0 to examine frequencies, means, percentages, and factor analysis. The following results were revealed. First, the targets were currently using broadband internet service in the order Company S > Company L > Company K > others. Excluding the others, Company K had the most conversions (from 96 to 78), followed by Company S (from 107 to 97), and Company L (from 43 to 97), which more than doubled the number of subscribers. The reasons for switching carriers in the past were as follows: for Company K, consumers switched to other companies because of unsatisfactory fee services; for Company S, consumers switched to other companies because of quality, advertising and promotional activities, and commitment periods ending; for Company L, the consumers switched to other companies because of fee, quality, and service; and for other companies, the consumers switched to other services because of unsatisfactory quality. Second, the analysis of the elements that determined whether a consumer will switch broadband internet service providers showed that college graduates and individuals who had switched carriers voluntarily in the past were more likely to switch to a new broadband internet service provider. Furthermore, passive consumers had a higher probability of switching. Moreover, when consumers were less satisfied with the fees and services, there was a greater chance of switching to another company.

Purpose: Sternal fractures after blunt thoracic trauma can cause significant pain and disability. They are relatively uncommon as a result of direct trauma to the sternum and open reduction is reserved for those with debilitating pain and fracture displacement. We reviewed consecutive 11 cases of open reduction and fixation of sternum and tried to find standard approach to the traumatic sternal fractures with severe displacement. Methods: From December 2008 to August 2010, the medical records of 11 patients who underwent surgical reduction and fixation of sternum for sternal fractures with severe displacement were reviewed. We investigated patients' characteristics, chest trauma, associated other injuries, type of open reduction and fixation, combined operations, preoerative ventilator support and postoperative complications. Results: The mean patient age was 59.3years (range, 41~79). The group comprised 6 male and 5 female subjects. Among 11 patients who underwent open reduction and fixation for sternal fracture with severe displacement, 6 cases had isolated sternal fractures and the other 5 patients had associated other injuries. Sternal fractures were caused by car accidents (9/11, 81.8%), falling down (1/11, 9.1%) and direct blunt trauma to the sternum (1/11, 9.1%), respectively. 3 of the 7 patients (42.9%) who underwent sternal plating with longitudinal plates showed loosening of fixation. Otherwise, none of the 4 patients who underwent surgical fixation using T-shaped plate had stable alignment of the fracture. Conclusion: Sternal fractures with severe displacement need to be repaired to prevent chronic pain, instability of the anterior chest wall, deformity of the sternum, and even kyphosis. In the present study, a T-shaped plate with a compression-tension mechanism constitutes the treatment of choice for displaced sternal fractures.

Purpose: Additional surgery is commonly recommended in gastric cancer patients who have a high risk of lymph node metastasis or a positive resection margin after endoscopic resection. We conducted this study to determine factors related to residual cancer and to determine the appropriate treatment strategy. Materials and Methods: A total of 28 patients who underwent curative gastrectomy due to non-curative endoscopic resection for early gastric cancer between January 2006 and June 2009 were enrolled in this study. Their clinicopathological findings were reviewed retrospectively and analyzed for residual cancer. Results: Of the 28 patients, surgical specimens showed residual cancers in eight cases (28.6%) and lymph node metastasis in one case (3.8%). Based on results of the endoscopic resection method, the rate of residual cancer was significantly different between the en-bloc resection group (17.4%) and the piecemeal resection group (80.0%). The rate of residual cancer was significantly different between the diffuse type group (100%) and the intestinal type group (20%). The rate of residual cancer in the positive lateral margin group (25.0%) was significantly lower than that in the positive vertical margin group (33.3%) or in the positive lateral and vertical margin group (66.7%). Conclusions: We recommended that patients who were lateral and vertical margin positive, had a diffuse type, or underwent piecemeal endoscopic resection, should be treated by surgery. Minimal invasive procedures can be considered for patients who were lateral margin positive and intestinal type through histopathological examination after en-bloc endoscopic resection.

The concern regarding inability to perform CPR properly was widespread, and few studies, however, have queried bystanders regarding their responses to an actual emergency. This study assessed how often CPR was performed by CPR-trained bystanders and what factors were associated with the performance and nonperformance of CPR by trained bystanders. From a 2,000 sample survey of the National Emergency Medical Center in Korea (2008), it extracted object persons who actually experienced an emergency situation, and examined closely the relationship of CPR education experience and CPR performance in an emergency. 169 completely interviewed, 23(13.6%) had CPR education experience and performed CPR in an actual emergency, 40(23.6%) had CPR education experience but didn't performed, 12 (7.1%) didn't have CPR education experience but performed, and 94(55.6%) neither had CPR education experience nor performed. Specifically, within bystanders who had CPR education experience, those who CPR was performed were different from those who CPR was not on medical emergency-related characteristics such as CPR knowledge(p=0.001), 1339 emergency phone number(p=0.006) and 1339 emergency services(p=0.001). Consequently, to consider social characteristics or an economic condition, various CPR teaching strategies should be prepared to continuously propel.

Purpose: Remnant gastric cancer (RGC) are generally detected at advanced stages or infiltration of adjacent organs. We retrospectively reviewed the surgical outcomes and clinicopathologic results of remnant gastric cancers that have operated during fourteen years in one institution of Korea. Materials and Methods: 34 patients who were diagnosed with RGC at Ajou University Hospital from April 1995 to October 2009 were enrolled. We analyzed the features of previous operation, and according to these results, surgical outcomes and clinicopathologic results for RGC were analyzed. Results: Of 34 patients, 20 patients had previously undergone distal gastrectomy for malignant disease, and 14 patients for benign disease. The period between previous operation and surgery for RGC in the patients underwent operation for malignant disease was shorter than that in benign patients (P<0.001). In surgical field, 31 patients (91.0%) were resected and curative resection was possible in 23 patients (67.6%). When 31 patients who underwent resection for RGC were divided into previous malignant and benign disease, there was no significantly different in terms of surgical outcomes and pathologic findings between two groups. Meanwhile, the patients who recently (after 2005) underwent surgery for RGC showed less advanced stage compared with the patients who underwent surgery before 2004. Conclusions: Resection was possible in the higher proportion (91.0%) of patients diagnosed with RGC compared with previous reports. The cause of previous operation did not effect on the surgical outcomes for surgery of RGC. Recent trend of RGC is to increase the proportion of early stage gastric cancer. Therefore, surgeons should consider curatively surgical resection for RGC the regardless of pattern of previous operation.

In this study, the patterns of people who get dental services from unqualified dental practitioners were identified by using "2006 National Dental Health Investigation". There were 4,543 people in total and the group was divided into two groups - those who had experience of receiving dental services from unqualified practitioners and of those who had not. The most pattern model was CHAID. It was patterned that 39% of those who are more than 68 years would experience such unqualified dental service, and it was found that 3% of those who are less than 33 years experienced such a service. It was found that 45% of those who are 55 or 68 years and woman would experience such unqualified dental service, and 32% of those who are 55 or 68 years and man experienced such a service. With the increase in health awareness, the burden of medical bills is also rising. However, cases of unqualified dental treatments that could cause extremely dangerous symptoms are also rising recently. Therefore it is most important to anticipate those groups who are most exposed to unqualified dental services, and educate them with appropriate information and publicise about the danger.

Although studies on Hepatitis A virus (HAV) were crucial in the establishment of the HAV infection prevention programs, no systematic investigation into HAV has been conducted since 1999. We retrospectively analyzed the data between January 2010 to December 2018 from all the patients who underwent HAV antibody tests at the Dankook University Hospital Health Care Center. Data were collected from 56,204 individuals. Overall, 34,834 (62.0%) individuals from this cohort were positive for HAV antibodies and the annual rate of anti-HAV antibody positivity was highest in 2010 (68.5%) and lowest in 2013 (54.8%). The average decline in the antibody positivity rate was 0.62% per year, showing a statistically significant difference (p < 0.001). In the over 40s age group, anti-HAV antibody positivity rates decreased from 89% in 2010 to 64% in 2018 (p < 0.001), with an annual decrease of 3.1%. In the over 30s age group, it decreased from 48.2% in 2010 to 34.7% in 2018 (p < 0.001), with an annual decrease of 1.82%. This study shows that the antibody positivity rate is decreasing across age groups but given that HAV infection poses more significant risks in older patients it is important to expand the evaluations of the current and future antibody positivity rates for HAV in various age groups.

Purpose: The purpose of this study was to examine the effect of music therapy on pain, depression in terminally-ill patients. Methods: The subjects for this study were collected from 44 patients who were admitted in F hospital, located in D city from July 1 to July 31 in 2008. The subjects were divided into two groups: 23 experimental group members and 21 control members. While the control group was not received any additional intervention, the experimental group was received music therapy intervention. Data analysis were performed by the chi-square test, t-test and ANCOVA with SPSS/WIN 12.0 Program. Results: The 1st hypothesis is, "the experimental group who received music therapy would have less pain score than the control group who did not receive music therapy", was rejected (F=2.33, p=.14). The 2nd hypothesis is, "the experimental group who received music therapy would have less depression score than the control group who did not receive music therapy", was supported (F=11.616, p=.001). These results demonstrated that music therapy to terminally patients was an effective method in decreasing depression. Conclusion: Based on the results of this study, Music therapy can be utilized as an effective nursing intervention for the terminally ill.

The purposes of this study were to examine the slacks purchases and wearing satisfaction among old-aged women who were highly dissatisfied with their bodies and fit due to physical changes and to provide some basic data needed to develop slacks patterns to meet their needs. A survey was taken among 223 old-aged women aged 60~79 living in Seoul. Using the SPSS 12.0 program, the collected data were analyzed in descriptive statistics, t-test, and crosstab. The result were as follows: the most used place for them to shop slacks was a market(including the Dongdaemun and Namdaemun market), which was followed by a department store and a discount store in the order. As for their preference for slacks according to age, those who were in their sixties most preferred straight-line slacks, while those who were in their seventies semistraight-type slacks. As for fit for each body part according to age, there were significant differences only in crotch length. Those who were in their seventies were more dissatisfied with crotch length than those who were in their sixties, feeling that crotch length was short. As for their experiences of repair after purchasing a pair of slacks, 82.5% said they had such an experience. Most of the repairs with length, waist and slacks width involved in size reduction.
