In this paper, a thickness compensation function is introduced to consider the shear deformation and warping effect resulting from increased thickness in the composite multi-cell wing box. The thickness compensation function is used to perform the structure optimization of the multi-cell. It is determined by minimizing the error of an analytical formula using solid mechanics and the Ritz method. It is used to define a structural performance prediction expression due to the increase in thickness. The parameter is defined by the number of spars and analyzed by the critical buckling load and the limited failure index as a response. Constraints in structural optimization are composed of displacements, torsional angles, the critical buckling load, and the failure index. The objective function is the mass, and its optimization is performed using a genetic algorithm.

목적: The purpose of this study was to evaluate the effect of scheduled ramosetron injection during hospitalized period in patients undergoing single port access total laparoscopic hysterectomy (SPA-TLH). 방법: In this prospective, randomized, double-blinded, placebo-controlled study, 131 patients who were undergoing SPA ?TLH in National Health Insurance Service Ilsan Hospital from March 2013 to May 2014 were enrolled. Patients were divided into two groups: the ramosetron group (0.3 mg i.v.; n=65), and the placebo group (normal saline i.v.; n= 66). Both groups received their respective injection on post-operative day 1 and day 2. The incidence of postoperative nausea and vomiting (PONV), the severity of PONV (numerical rating scale 0-10), and the use of rescue antiemetic requirements during the first 24 h after surgery were evaluated. 결과: Demographic and perioperative differences were not observed between the two groups. The incidence of postoperative nausea and vomiting in the ramosetron group and the placebo group were 40.1% and 42.7%, respectively (p=0.213). However, there was a significant difference between the groups in the scale of PONV during 24 hours and 48 hours after surgery (p=0.042, p=0.034, respectively). The use of rescue antiemetics was significantly lower in the roamsetron group (p=0.021). 결론: After general anesthesia in the same fashion, the scheduled injection of ramosetron reduced the intensity of PONV and the use of rescue antiemetics. Administration of ramosetron can be considered not only immediately after the SPA-TLH but also during the recovery period.

본 논문에서는 마음읽기 중재가 ASD 아동의 이야기 회상산출 능력에 미치는 효과를 알아보고자 하였다. 연구는 행동간 중다 기초선 설계로 이루어졌으며 기초선 1회기, 중재 8회기, 중재철회 1회기로 진행되었다. 연구 결과, 마음읽기 중재를 사용하였을 때 대상아동의 이야기 회상산출 능력이 증가되었다. 이를 통해 마음읽기 중재가 ASD 아동의 이야기 회상산출에 긍정적인 효과가 있음을 확인할 수 있었다. The purpose of this study was to investigate the effect of mind reading intervention on the recall of ASD children. This study was designed as a single case study (A-B-A). As a result of the study, when the mind reading intervention was used, the ability of the target child to recall the story was increased. This suggests that the mind reading intervention has a positive effect on the story recall of ASD children.
