This study analyzed the inflow factors of Yangjae Citizen’s Forest Park using social big data generated online. To this end, the applicability of the emotional information analysis method is to be confirmed as a method of analyzing the perception of the city park and confirming the difference in the characteristics and use of the park. The analysis is based on big data, and as the core of the study is keyword network analysis, the methodology of the ‘emotional information analysis method’ patented by the author was applied. As a result of the analysis, among the influx factors of Yangjae Citizens’ Forest recognized by citizens, the most positive emotional factor was derived as a factor related to ‘park contents’, and the negative emotional factor was derived as a factor related to ‘park management’. These research results suggest that more in-depth program development and operation are needed to discover ‘park contents’ when implementing urban park revitalization support projects in the future

박상훈,정범석 한국막학회 2016 한국막학회 총회 및 학술발표회 Vol.2016 No.11

PEBAX®는 폴리에테르가 우수한 CO2용해도를 나타내어 기체분리막의 소재로 주목받고 있지만 폴리아마이드의 crystallinity로 인해 투과성능면에서 제약을 받는다고 알려져 있다. 본 연구에서는 PEBAX® 막의 기체투과특성을 향상시키기 위해 합성된 aluminosilicate hollow nanoparticles를 막 내부에 고르게 분산시켜 함량별로 혼합막을 제조한다. 분산된 나노입자의 함량에 따른 CO2 용해도 증가, 확산 속도의 증가로 인하여 선택도와 투과도의 향상을 예측할 수 있다. 첨가된 나노입자의 morphology와 yield를 확인하고, 첨가량이 증가할수록 선택도의 변동없이 투과도가 증가하는 것을 알 수 있다.

Research about spherical shells been applying most usually is achieved by many investigators already and generalized equation has been derived. But, existent research is limited in case that spherical shell's roof rigidity is isotropy or orthotropy, and research that consider periodicity of rigidity-distribution that can happen by doing spherical shell's roof system by lattice system is not gone entirely. The purpose of this paper is applying Galerkin method to spherical shell that model periodicity of roof rigidity distribution that appear by roof lattice form of large space structure and develop structural analysis program that formularize. Rigidity-model of this research selects that of spherical shell which has 2-way grid. In this paper, buckling-strength and deformation distribution of isotopic spherical shell and 2-way grid spherical shell obtained by developed program could confirm the reliability by comparison with result of existent research.

This study is a preliminary study to establish the criteria for evaluating the performance of the window-integrated ventilation system. This study analyzed various references that can evaluate the performance of the ventilation system and established the evaluation method. In addition, the performance evaluation method was quantitatively evaluated by conducting a pilot experiment to verify and supplement the performance evaluation method of the ventilation system. The performance of the ventilation system was categorized into ventilation, air quality, airtightness, noise, visibility and view according to the evaluation category. In particular, according to the ventilation and air quality evaluation, it was found that the indoor carbon dioxide concentration can be reduced by about 14 % when the window-integrated ventilation system is applied. The ventilation performance evaluation method and experimental data of this study will serve as basic data for subsequent studies to establish comprehensive performance evaluation criteria for similar ventilation systems.

Laparoscopic sleeve gastrectomy has become a standard procedure in bariatric surgery owing to its efficacy and simplicity. However, this procedure can cause life-threatening complications such as a gastric staple-line leak. A 24-year-old woman was transferred to the emergency department for evaluation of epigastric pain. Nine days prior to transfer, she underwent laparoscopic sleeve gastrectomy at another institution. Abdominal computed tomography (CT) revealed fluid collection with air density along the left subphrenic space and gastrosplenic ligament area. Intravenous antibiotics and total parenteral nutrition were initiated. She underwent percutaneous catheter drainage. On postoperative day 18, an esophagogastroduodenoscopy was performed to assess the site and size of the leak, and revealed a leak at the proximal staple line just below the gastroesophageal junction. A newly designed, fully covered antimigratory esophageal stent was placed to cover the leak from the distal esophagus to gastric midbody. Follow-up abdominal CT demonstrated improvement of the fluid collection at the location of the previous gastric leak. The stent was removed 3 weeks after insertion, and a barium study confirmed no more leakage. In this case, we experienced that the newly designed esophageal stent was safe and effective for preventing migration in the management of leak after laparoscopic sleeve gastrectomy.

Purpose: To identify the accuracy of postoperative implant alignment in minimally invasive surgery total knee arthroplasty (MIS-TKA), based on the degree of varus deformity. Materials and Methods: The research examined 627 cases of MIS-TKA from November 2005 to December 2007. The cases were categorized according to the preoperative degree of varus deformity in the knee joint in order to compare the postoperative alignmentof the implant: less than 5° varus (Group 1, 351 cases), 5° to less than 10° varus (Group 2, 189 cases), 10° to less than 15° varus (Group 3, 59 cases), and 15° varus or more (Group 4, 28 cases). Results: On average, the alignment of the tibial implant was 0.2±1.4°, 0.1±1.3°, 0.1±1.6°, and 0.3±1.7° varus, and the tibiofemoral alignment was 5.2±1.9°, 4.7±1.9°, 4.9±1.9°, and 5.1±2.0° valgus for Groups 1, 2, 3, and 4, respectively, in the preoperative stage, indicatingno difference between the groups (p>0.05). With respect to the accuracy of the tibial implant alignment, 98.1%, 97.6%, 87.5%, and 86.7% of Groups 1, 2, 3, and 4, respectively, had 0±3° varus angulation, demonstrating a reduced level of accuracy in Groups 3 and 4 (p<0.0001). There was no difference in terms of tibiofemoral alignment, with 83.9%, 82.9%, 85.4%, and 86.7% of each group, respectively, showing 6±3° valgus angulation (p>0.05). Conclusion: Satisfactory component alignment was achieved in minimally invasive surgery in total knee arthroplasty, regardless of the degree of varus deformity.
