Objectives: The purpose is to identify the risk of infection at the dentist by examining awareness of housekeeping surface contamination and determining whether current practices require improvement. Method: Samples were collected and tested using ATP meters to evaluate the pollution levels of each clinic. Employees were also surveyed to find out if they had received housekeeping surface management training or felt the need. Results: The results of the staff survey revealed that only 10% of respondents had been trained in housekeeping surface management. Of the 90% who had no training, their lack of knowledge was the highest on floor contamination. Conclusion: The findings revealed low level of awareness about housekeeping surface management due to the lack of training and standards. The development of guidelines, therefore, is imperative if current practices are to be improved

김하은,백효채,김송이,박무석,이진구 대한흉부외과학회 2018 Journal of Chest Surgery (J Chest Surg) Vol.51 No.6

Background: Airway anastomotic complications are a leading cause of mortality after lung transplantation. Among the factors that cause airway complications, preoperative steroid use has been considered to be related with postoperative airway healing. We analyzed the influence of preoperative steroid use on postoperative airway complications. Methods: The medical records of 66 double-lung transplant recipients from January 2014 to December 2015 were reviewed. Forty patients were prescribed steroids preoperatively. The daily steroid dose was standardized using the patient’s body mass index (BMI). Patients who received preoperative steroids were sub-divided into high-dose (HD) and low-dose (LD) groups (cut-off value, 1.6 mg/BMI/day). Results: Thirteen patients suffered from airway complications postoperatively (bronchopulmonary fistula, 9; bronchial stenosis, 4). There was a tendency for early development of airway complications in the steroid use group compared to the non-steroid use group, but it was not significant (percentage free from airway complications in year 1: non-steroid group, 90.9% vs. steroid group, 79.2%; p=0.43). The percentage of patients in the LD and HD groups who were free from airway complications in year 1 was not significantly different (84.0% vs. 77.8%, p=0.39). Conclusion: The airway complication rate did not vary significantly according to steroid use. Additionally, in patients who received preoperative steroids, the dose did not affect the rate of development of airway complications.

Purpose: This study is to assess the relationship between job stress and health promoting behaviors among nurses working in intensive care unit. Methods: A cross-sectional survey was conducted between 2 March and 27 April 2011. A total of 195 nurses completed study. Information was obtained on demographic characteristics, job stress, and health promoting behaviors. Univariate analyses were done to describe study variables. Results: Job stress significantly differed according to musculoskeletal symptoms, while health promoting behaviors significantly differed according to subject’s age, working duration, marital status and musculoskeletal symptoms. Job stress was negatively associated with health promoting behaviors. Conclusion: The findings of this study suggest that nursing intervention programs reducing nurses’ job stress can lead to increased health promoting behaviors.

김하은,정조원,신유림,박한기,박영환,신홍주 대한흉부외과학회 2016 Journal of Chest Surgery (J Chest Surg) Vol.49 No.3

Patients with venoarterial extracorporeal membrane oxygenation (ECMO) frequently suffer from pulmonary edema due to left ventricular dysfunction that accompanies left heart dilatation, which is caused by left atrial hypertension. The problem can be resolved by left atrium (LA) decompression. We performed a successful percutaneous LA decompression with an atrial septostomy and placement of an LA venting cannula in a 38-month-old child treated with venoarterial ECMO for acute myocarditis.

김하은,홍경훈 한국콘텐츠학회 2023 한국콘텐츠학회논문지 Vol.23 No.10

With the help of information technology This study analyzed the factors affecting parental satisfaction with telepractice of children with language development disabilities: 13 main guardians of children with language development disabilities were asked to complete the satisfaction survey questionnaire after remote language rehabilitation, and variables related to parental satisfaction were analyzed using questionnaire data. Among the subject-related variables, children's acceptance vocabulary score was significantly correlated with overall parental satisfaction, and among the components of telepractice, system technology and tools, program ease and content quality, parent education programs, language rehabilitation's lapo-forming ability, and language rehabilitation system usage ability were significantly correlated with parental satisfaction. This study suggests the importance of selecting appropriate targets and establishing a telepractice plan in the implementation of telepractice, and suggested major factors to improve the effectiveness of telepractice.

The purpose of this study was to examine the effect of a Interhemispheric Transfer exercise program on performance-related physical fitness factors of 18 elite high school fencers aged 17 to 19 years old. Participants were randomly assigned into 2 groups (EG, n=9), Cerebral Interhemispheric Transfer exercise program, and Control Group(CG, n=9) after considering gender ratio. Exercise intervention was performed 3 times a week for 4 weeks, and before and after the intervention, grip strength, back muscle strength, agility, reaction time, and flexibility were measured. The results and conclusions of this study are as follows. The interaction was found in the dominant grip strength (p<.05), but there was no significant interaction in the non-dominant grip strength. Agility was interactive (p<.01) and sig- nificantly increased in the control group (p<.01). Reaction time was significantly increased in both groups in the upper body reaction per- formance (p<.01). and there was also interaction between groups (p<.05). The number of dominant side foot step was significantly in- creased in both groups(p<.05, p<.01). but, In the number of non-dominant side increased significantly after intervention only in the control group (p<.01). Flexibility was increased significantly in both groups(p<.05, p<.01). The Interhemispheric Transfer exercise program had a positive effect on the strength, reaction time, and flexibility of the fencers, but there was no significant difference in agility. In the fu- ture, it is judged that additional research is needed to improve the performance of elite fencers through research on long-term non-dom- inant hand training programs.

김하은,백효채,정수진,박무석,김송이,이진구 연세대학교의과대학 2021 Yonsei medical journal Vol.62 No.2

Purpose: Calcineurin inhibitor (CNI) use has improved lung transplantation outcomes. However, significant perioperative complicationsin patients receiving CNI can deteriorate the early course of lung transplantation. To date, there is no consensus regardingthe optimal agent for the induction regimen after lung transplantation. We aimed to determine the efficacy of basiliximab inductionwith delayed CNI initiation in the prevention of acute complications without compromising immunosuppression inhigh-risk patients. Materials and Methods: Between January 2013 and December 2019, 236 patients at a single lung transplant center were retrospectivelyreviewed. Forty-one patients (17.4%) received basiliximab induction, and 195 patients (82.6%) received a routine tripledrugregimen without induction. The primary endpoint was postoperative acute kidney injury with several other postoperativeoutcomes as secondary end-points. Results: Preoperatively, the induction group had a higher proportion of patients who were admitted before transplantation(95.1% vs. 47.7%, p<0.001) and received intensive unit care (90.2% vs. 33.8%, p<0.001) and extracorporeal membrane oxygenation(ECMO) (87.8% vs. 20.0%, p<0.001) compared to the non-induction group. No significant differences were observed in the incidenceof acute rejection between groups (p=0.657), although lower incidence of postoperative complications, including acutekidney injuries or culture-proven infections, were observed in the induction group. However, the differences were not statisticallysignificant. A subgroup analysis of high-risk and preoperative ECMO support groups showed similar results. Conclusion: Basiliximab induction with delayed CNI initiation for high-risk patients might decrease the incidence of perioperativecomplications, including acute renal failure, without increasing the risk of acute rejection.

Positive, negative, and nil effects of connectives in written stories: Analysis by proficiency groups

김하은,구성진,배정옥 경희대학교 언어정보연구소 2015 언어연구 Vol.32 No.S

Inconsistent findings about the significance of connectives in prior studies may be due to the fact that connectives were not analyzed according to their different semantic types as well as language users’ proficiency levels. The present study therefore divided connectives into four semantic types (additive, adversative, causal, and temporal) and examined how much their occurrences were related to the quality of free writing and whether the results varied because of proficiency levels. The participants were groups of different English writing proficiency (N = 242): Korean EFL elementary school immersion students and native English speakers who were middle or high school students attending an army-based American school. They were given a writing task which required them to create a story based on a picture. The stories were analyzed for connective occurrences and writing qualities such as content, text length, and vocabulary. The results show the following. As students become more proficient, the overall occurrences of connectives decreased. Additive and temporal connectives were most prevalent. However, their effects on writing qualities were different. In the stories by EFL students, the frequent occurrences of additive connectives negatively influenced the quality of content, while temporal connectives enhanced it. Such effects did not exist in the stories by native speakers; none of the connective types made any significant influence on the quality of content, indicating that with or without connectives content is comprehensible in the writings of proficient writers.
