Background/Aims: Surgeons and endoscopists have started to use endoscopically inserted double pigtail stents (DPTs) in the management of upper gastrointestinal (UGI) leaks, including UGI anastomotic leaks. We investigated our own experiences in this patient population. Methods: From March 2017 to June 2020, 12 patients had endoscopic internal drainage of a radiologically proven anastomotic leak after UGI surgery in two tertiary UGI centers. The primary outcome measure was the time to removal of the DPTs after anastomotic healing. The secondary outcome measure was early oral feeding after DPT insertion. Results: Eight of the 12 patients (67%) required only one DPT, whereas four (33%) required two DPTs. The median duration of drainage was 42 days. Two patients required surgery due to inadequate control of sepsis. Of the remaining 10 patients, nine did not require a change in DPT before anastomotic healing. Nine patients were allowed oral fluids within the 1st week and a soft diet in the 2nd week. One patient was allowed clear oral feeds on the 8th day after DPT insertion. Conclusions: Endoscopic internal drainage is becoming an established minimally invasive technique for controlling anastomotic leak after UGI surgery. It allows for early oral nutritional feeding and minimizes discomfort from conventional external drainage.

Background: Since December 2010, online computerized prospective drug utilization review (pDUR) has been implemented in Korea. pDUR involves the review of each prescription before the medication is dispensed to the individual patient. The pDUR is performed electronically by Health Insurance Review & Assessment Service (HIRA), which is a Korean governmental agency, and then HIRA provides medical institutions and pharmacies with information that can be helpful to them in preventing potential drug problems such as drug/drug interactions or ingredient duplication. The aim of this study was to assess the impact of the Korean pDUR implementation on the proportion of drug-drug interactions (DDIs) using claims data from HIRA. Methods: A before-after comparison of the prevalence of DDIs between prescription was conducted, using HIRA administrative claims data of medical institution from January 2010 to December 2011. The analysis unit was the prescription issued and pairs before and after. The main outcome measures were the proportion of DDIs within- (control group) or between- physician encounters. To examine the difference, a paired t-test was applied. Results: We found that DDIs proportion between prescription decreased significantly (t=3.04, p=0.0026) after the implementation of pDUR, whereas there is no significant reduction within prescription (t=1.15, p=0.2518). With respect to the prevalence of DDIs between drug groups, the most dramatic reduction was occurred between 3-hydroxy-3-methylglutaryl coenzyme A reductase inhibitors and anti-fungal agents. Conclusion: It seems effective that giving a direct feedback to prescribers by a prospective DUR. Further research is needed to assess the impact of DUR to final outcomes such as hospitalization.

This study was conducted to analyze the effect of male middle school students' eating school breakfast on their attitudes toward breakfast and school breakfast. In addition, the effect of school breakfast on breakfast-related eating behaviors and academic achievement was investigated. The study subjects were selected from a male middle school located in Gyeonggi-do, Republic of Korea. Breakfast was provided at the school for 7 weeks during the 2nd semester of the year 2006. Two sophomore classes were selected for the experimental study. All the students from one class (n = 34; School Breakfast Eaters) have eaten school breakfast while none of the students from the other class (n = 33; School Breakfast Non-eaters) have done so. About two weeks after the school breakfast service was terminated, questionnaires were distributed to the two classes and the responses were analyzed. The results showed that School Breakfast Eaters had more positive attitudes toward breakfast and school breakfast than School Breakfast Non-eaters. In addition, School Breakfast Eaters perceived the positive effect of eating breakfast on their school life more highly than School Breakfast Non-eaters. However there was no significant difference between the two groups in their breakfast eating behaviors in terms of breakfast skipping when the breakfast service was not available. No significant difference was found between the two groups with regards to math score variation before and after school breakfast service. In conclusion, school breakfast for 7 weeks had positive effects on male middle school students' attitudes toward breakfast and school breakfast, although the effect was not confirmed in their breakfast-related eating behaviors after the school breakfast service was terminated

Objectives: The purpose of the study was to examine the recognition and satisfaction of dental care customers after 1 year national health insurance coverage of dental scaling. Methods: A self-reported questionnaire was completed by 477 dental care customers in Gyeongbuk, Busan, Yangsan, and Gyeonggido from July 18 to September 30, 2014 after receiving informed consents. The questionnaire consisted of general characteristics of the subjects(5 items), subjective awareness of oral health(4 items), recognition of scaling(5 items), and recognition and satisfaction of scaling health insurance(5 items). Data were analyzed using SPSS version 20.0 program. Results: Those who recognized the national health insurance coverage of dental scaling accounted for 80.1 percent and 47.2 percent of them got the health insurance coverage via media advertisements. Those who received the scaling service by health insurance coverage accounted for 73.8% and 66.2% of them were very satisfied with the service. Among the customers, 91.8% were satisfied with scaling health allotment. There was a statistical significance between scaling health insurance and subjective oral condition recognition(p<0.01). Through the health insurance coverage scaling service, the oral health in Korea will improve much. Conclusions: The expansion of health insurance coverage of scaling service will provide the universal oral health care for all people. Owing to low cost service, people will actively try to come in contact with public health service in the future.

Background: As of July 2015, per diem payment was changed from fee for service Therefore, this study aims to analyse changes in medical charges and medical services before and after enforcement of the palliative care, targeting palliative care wards in a general hospital, and provide basic data needed for development of per diem payment. Methods: The subjects of the study were a total of 610 cases consisting of 351 patients of service fee who left hospital (died) from July 2014 to June 2016 and 259 ones of per diem payment at Chosun University Hospital in Gwangju Metropolitan City. Results: The results are summarized as follows. First, after the palliative care system was applied, benefit medical service charges and insurance increased significantly (p<0.001). As benefit medical service charges increased, benefit private insurance payment increased significantly (p<0.001). Second, after the per diem payment was applied, total private insurance payment to medical institutes decreased significantly (p=0.050) and non-benefit also decreased significantly (p=0.001). Conclusion: It is suggested that additional rewards in the obligatory palliative care items should be continuously remedied and monitored to provide good quality hospice palliative care.

Climate changes, such as increasing of $CO_2$ concentration and global warming, will impact on the carbonation service life of concrete structures. Moreover, slag blended concrete has a lower carbonation resistance than control concrete. This study presents a probabilistic numerical procedure for evaluating the impact of climate change on carbonation service life of slag blended concrete. This numerical procedure considers both corrosion initiation period and corrosion propagation period. First, in corrosion initiation period, by using an integrated hydration-carbonation model, the amount of carbonatable substances, porosity, and carbonation depth are calculated. The probability of corrosion initiation is determined through Monte Carlo method. Second, in corrosion propagation period, a probabilistic model is proposed to calculate the critical corrosion degree at surface cracking, the probability of surface cracking, and service life. Third, based on the service life in corrosion initiation period and corrosion propagation period, the whole service life is calculated. The analysis shows that for concrete structures with 50 years service life, after considering climate changes, the service life reduces about 7%.

According to software growth, also software maintenance has been continuously improving. In addition, the existing concept of software maintenance process demands operational management and improvement of service task. However, when we perform maintenance task, we have several constraints about applying service based requirement to system. Therefore, in order to solve these problems, we need a study of task of process for service based maintenance. In this paper, we propose a Service based Software Maintenance Process. Proposed process based on MaRMI-RE standard for software development and maintenance and compares it with the service based representative standards. In a related works, we study activity of ITIL and identify activities and tasks for maintenance. After this, identified activities and tasks compare with activities of MaRMI-RE. And then, we derive activities and tasks of a Service based Software Maintenance Process. Finally, we validate a result by comparing the proposed process with a general service operational process.
