Background: The current evidence on the safe use of supraglottic airway for pediatric laparoscopic surgeries is limited. Although i-gel has been successfully used in adult laparoscopic surgeries, to our knowledge, no studies have compared it to the endotracheal tube (ETT) in pediatric laparoscopic surgeries. This study evaluated the effectiveness of i-gel over ETT with regards to the respiratory and hemodynamic parameters during pediatric laparoscopic surgeries. Methods: A total of 60 pediatric patients undergoing elective laparoscopic surgeries were randomly allocated to either the i-gel or ETT groups. Anesthetics used included ketamine, sevoflurane, and rocuronium. The primary outcome measured was the peak airway pressure (PAP) and the secondary outcomes measured were leak fraction, endtidal CO2, respiratory rate, insertion time, heart rate, blood pressure and perioperative complications. Results: The PAP during surgeries was higher in the ETT group than in the i-gel group. There were no statistically significant differences in the leak fraction, end-tidal CO2, and respiratory rate. The i-gel group had a shorter insertion time compared with the ETT group. The changes in heart rate were comparable in both groups. However, systolic and diastolic pressures were higher in the ETT group following intubation, before and after the creation of pneumoperitoneum. The incidence of perioperative complications was similar in both groups. Conclusions: The i-gel provided adequate ventilation with lower PAP compared with ETT. In addition, it provided minimal hemodynamic changes compared with ETT. Therefore, the i-gel may provide a suitable alternative to ETT in pediatric laparoscopic surgeries.

In recent years of the color science field, there has been a lot of interest in research projects on the spectral prediction model, which can quantify not only color but also light and texture. In the absence of predictive models and measuring instruments, gloss management has received attention in color management. In this study, two surveys were conducted to obtain the visual satisfaction and color accuracy of the hard trim components in car interiors. First, the Lightness determined the most significant color attribute that affects the degree of gloss, and we revealed the correlation between Lightness and glossiness. Second, to find the degree of gloss that can satisfy both emotional and functional aspects, we conducted an irradiation and scratch resistance / staining test. In this study, 88 gray / beige scale group samples were searched to find the proper gloss for automotive interior hard trim parts, with correlation analysis through color / gloss measurement, designer and scratch resistance / stain. The following conclusions were made through analysis and findings. ① from lightness 25 to 60, ② from lightness 60 to 70, ③ over Lightness 70 color samples corresponding to Lightness indicate that the glossiness criteria should be set separately. As a result of the survey on the preferred gloss for color experts, up to 1.5GU of lightness 25 was preferred, and scratch resistance and stain resistance were satisfactory. Finally, the preferred glossiness survey of color experts favored 1.5GU on a Lightness 25, while the scratch and contamination acceptance criteria were all satisfied. In conclusion, we should controlGU such as between Lightness 25 and Lightness 60 is 1.5 ±0.2GU, between Lightness 60 and Lightness 70 is 2.0 ±0.2GU, and between Lightness over 70 is 2.5 ±0.2GU. However, it is recommended to combine visual evaluation.
Thoracomyoplasty for Chronic Empyema and Osteoradionecrosis of the Chest Wall

Herein, we report a case in which thoracomyoplasty was performed to manage chronic postlobectomy empyema (PLE). A 54-year-old male patient with a surgical history of right upper lobectomy and thymectomy 35 years previously who had undergone adjuvant ra- diotherapy presented with purulent discharge on the anterior chest wall. The patient was diagnosed with chronic PLE with ascending infection and concurrent osteonecrosis of the parasternum. Proper drainage was performed for local infection control and the dead spaces were successfully closed with muscle flaps. There have been no complications to date.
가정형 호스피스·완화의료에서 인생 회고 기법을 활용한 노래 중심 음악치료가 환자와 주 돌봄 가족의 삶의 질과 가족 관계에 미치는 영향

본 연구는 인생 회고 기법을 활용한 노래 중심 음악치료가 가정형 호스피스·완화의료 서비스를 받고 있는 환자와 주 돌봄 가족의 삶의 질과 가족 관계에 미치는 영향을 규명하기 위해 실시하였다. 연구 대상은 I광역 시 B구 C대학병원의 가정형 호스피스 완화의료 서비스 이용 가족 중 자발적으로 연구 참여에 동의한 환자와 주 돌봄 가족 1인 10쌍으로 총 20명이었다. 사전 검사 후, 지나온 삶을 회고하고 지나온 과거를 재경험하며 자신의 삶에 가치를 부여하도록 유도하는 인생 회고 기법을 활용한 노래 중심 음악치료 프로그램을 주 2회 씩 2주간 총 4회기 중재하고, 사후 검사를 시행하였다. 대상자들의 변화를 측정하기 위해 ‘호스피스 암 환자 의 삶의 질 측정 도구(Hospice Quality of Life Scale: HQLS)’, ‘삶의 질 측정 도구(Quality of Life: QOL)’ 그리고 ‘가족 관계의 질 측정 도구(Quality of Relationship between caregiver and patient)’를 사용하였다. 통계 분석 결과, 가정형 호스피스·완화의료 환자(Z=-2.805, p<01)와 주 돌봄 가족(Z=-2.701, p<.01)의 삶의 질에 유의미한 향상이 나타났으며, 가족 관계의 질(Z=-2.803, p<.01) 역시 통계적으로 유의미하게 증진되었다. 이러한 결과들은 총체적인 돌봄에 의한 환자와 가족의 삶의 질 향상이라는 호스피스·완화의료 의 목적과 목표에 부합하는 것으로, 가정형 호스피스·완화의료 환자와 주 돌봄 가족의 삶의 질과 가족 관계의 질 향상을 위한 음악치료 적용의 필요성을 시사한다. The purpose of this study was to investigate the effect of song-oriented music therapy using life-retrospective techniques on the quality of life and family relationship of patients and primary caregivers receiving home-based hospice and palliative care services. The subjects of this study consisted of 10 pairs of patients and one of his(her) primary caregivers, a total of 20 subjects. After the pre-test, a song-oriented music therapy program using life-retrospective techniques that induce reflecting the past, re-experiencing the past, and giving value to life was performed twice a week for a total of 4 sessions for 2 weeks; followed by a post-test. The tools used to measure the changes in subjects were Hospice Quality of Life Scale (HQLS), Quality of Life (QOL), and Quality of Relationship between caregiver and patient. The results of statistical analysis showed a significant improvement in the quality of life of home-based hospice and palliative care patients (Z=-2.805, p<01), primary caregivers (Z=-2.701, p<.01), and quality of the relationship between caregiver and patient (Z=-2.803, p<.01). These results are consistent with the goals and objectives of hospice and palliative care in improving the quality of life of patients and families by holistic care and signifies that the promotion of home-based hospice and palliative music therapy are strongly required to improve the patients’ and caregivers’ quality of life and family relationship.
