Jae Min Lee,Yehyun Park,Jin Myung Park,Hong Jun Park,Jun Yong Bae,Seung Young Seo,Jee Hyun Lee,Hyung Ku Chon,Jun-Won Chung,Hyun Ho Choi,Jun Kyu Lee,Byung-Wook Kim,Endoscopic Sedation Committee of the 대한소화기내시경학회 2022 Clinical Endoscopy Vol.55 No.5

Procedural sedation has become increasingly common in endoscopy. Sedatives and analgesics induce anxiolysis and amnesia. In addi- tion, an appropriate level of sedation is necessary for safe procedures including therapeutic endoscopy. Midazolam and propofol are the most commonly used drugs in sedative endoscopy. In recent years, the need to ascertain the safety and effectiveness of sedation has in- creased in practice. Therefore, new sedatives and analgesic drugs for optimal sedative endoscopy, have recently emerged. This article reviews the characteristics of sedatives and analgesics, and describes their clinical use in gastrointestinal endoscopy.

Core curriculum for sedation in gastrointestinal endoscopy with a focus on practice: a proposal from the Korean Society of Gastrointestinal Endoscopy

Hong Sub Lee,Yun Jeong Lim,Jong-Jae Park,Endoscopic Sedation Committee of Korean Society of Gastrointestinal En 대한소화기내시경학회 2025 Clinical Endoscopy Vol.58 No.2

Ideal sedation education for gastrointestinal endoscopy should encompass all medications used in sedation therapy, and facilitate appropriate application in clinical practice by combining theoretical and practical education according to each country’s situation. The educational goals for endoscopic sedation in Korea have already been announced, and theoretical training is regularly conducted by the Korean Society of Gastrointestinal Endoscopy (KSGE). However, no official core curriculum for sedation during gastrointestinal endoscopy exists in Korea. Therefore, a practical curriculum aligned with Korea’s clinical context should be developed. The Endoscopic Sedation Committee of KSGE has identified these challenges and proposed a core curriculum for sedation during endoscopy. Firstly, in terms of theory, it would be beneficial to maintain current education. Secondly, since practical training is still lacking, it would be beneficial to have practical hands-on training. To accomplish this, each simulation center should provide basic practical training such as airway maintenance and advanced teamwork skills. This review presents a detailed curriculum for safe sedation in gastrointestinal endoscopy, developed based on Korea’s specific needs and supported by current literature.

Sedat Cos gun,Sevim Ünügür Çelik,Abdulhadi Baykal,Ayhan Bozkurt 한국물리학회 2010 Current Applied Physics Vol.10 No.1

Intrinsically proton conducting organic electrolytes based on 2-perfluoroalkyl-ethyl-azides were synthesized via 1,3 cycloaddition between 2-perfluoroalkyl-ethyl-azide and alkynes. FT-IR, elemental analysis and NMR methods were used to characterize the resulting organic electrolytes. Thermal properties were analyzed with thermogravimetric analysis (TGA) and differential scanning calorimetry (DSC) and the morphology of the organic electrolytes was studied with X-ray diffraction (XRD). The effect of chain length on proton conductivity was investigated with impedance spectrometer. Dielectric constant and electrical modulus formalisms were analyzed and the maximum proton conductivity was measured as 10-2 mS/cm at 180 ℃.

The tension in Turkish teacher education: Conflict and controversy during the transformation from an academic approach to a professional approach

Sedat Yüksel 서울대학교 교육연구소 2008 Asia Pacific Education Review Vol.9 No.3

Most of the reforms, which have been undertaken in the last 30 years in the Turkish educational system, are about teacher education, When we examine the teacher education curriculum from the perspective of these reforms, it has been observed that there is a controversy between the academic and professional approaches used in these curricula. While the reforms undertaken in 1982 and 1997 were in favor of the academic approach, the latest reform undertaken in 2006 was made to strengthen the professional aspects of teacher education curriculum. In this paper, Turkish teacher education reforms are introduced in the light of the professional and the academic approaches, which have always been the topic of discussions about teacher education.

Sedat KELEŞ,Alkan GÜNLÜ,Emin Zeki BAŞKENT 한국산림과학회 2012 Forest Science And Technology Vol.8 No.4

In this paper, we developed empirical relationships between crown closure and Landsat Thematic Mapper (TM) and IKONOS spectral response in a forest ecosystem in Turkey. The linear relationships between the crown closure and satellite images were examined and for that the normalized difference vegetation index (NDVI) was generated for correlation analysis. Satellite images were georeferenced with respect to corresponding forest stand type maps for the same area. The digital numbers (DNs) in all bands were positively correlated with the crown closure in Landsat-7ETM image. Regarding the Landsat ETM+, the DN of NIR band (band 4) had the highest correlation coefficient value with the crown closure (r=0.715), and the DN of blue band (band 1) had the lowest correlation value with the crown closure (r=0.373) and explains 51.1% and 13.9% of data variability, respectively, in Landsat-7 ETM image. In IKONOS image, the DNs in three bands (red, green and NIR) were positively correlated with the crown closure at the level of r=0.385, r=0.359 and r=0.829, respectively. The NIR band of the Landsat-7-ETMþimage showed the highest correlation with the NDVI (r=0.886) and the red band had the lowest correlation with the NDVI (r=0.419),while the IKONOS image showed that the NIR band had the highest correlation with the NDVI (r=0.781) and the green band resulted in the lowest correlation with the NDVI (r=0.367). Results also indicated that the relationships between the crown closure and the NDVIs of Landsat-7 ETM and IKONOS were positively correlated with r=0.794and r=0.871, respectively.

PURPOSE In this study, we aimed to evaluate the amount of marginal gap with two different substructure materials using identical margin preparations. MATERIALS AND METHODS Twenty stainless steel models with a chamfer were prepared with a CNC device. Marginal gap measurements of the galvano copings on these stainless steel models and Co-Cr copings obtained by a laser-sintering method were made with a stereomicroscope device before and after the cementation process and surface properties were evaluated by scanning electron microscopy (SEM). A dependent t-test was used to compare the mean of the two groups for normally distributed data, and two-way variance analysis was used for more than two data sets. Pearson's correlation analysis was also performed to assess relationships between variables. RESULTS According to the results obtained, the marginal gap in the galvano copings before cementation was measured as, on average, 24.47 ± 5.82 µm before and 35.11 ± 6.52 µm after cementation; in the laser-sintered Co-Cr structure, it was, on average, 60.45 ± 8.87 µm before and 69.33 ± 9.03 µm after cementation. A highly significant difference (P<.001) was found in marginal gap measurements of galvano copings and a significant difference (P<.05) was found in marginal gap measurements of the laser-sintered Co-Cr copings. According to the SEM examination, surface properties of laser sintered Co-Cr copings showed rougher structure than galvano copings. The galvano copings showed a very smooth surface. CONCLUSION Marginal gaps values of both groups before and after cementation were within the clinically acceptable level. The smallest marginal gaps occurred with the use of galvano copings.

A Study on Optimum Machinability of NiTi Shape Memory Alloy Via AWJ

Sedat Güven,Meltem Altın Karataş,Hasan Gökkaya 한국정밀공학회 2024 International Journal of Precision Engineering and Vol.25 No.3

The high ductility behaviour and high hardening of Nickel–Titanium (NiTi) alloys during cutting make them one of the alloys with low machinability. In addition, poor chip breakage and high tool wear are observed when machining these materials with conventional manufacturing methods. One of the unconventional processing methods, abrasive water jet (AWJ), is an alternative method for cutting low machinability materials. In this study, NiTi shape memory alloy (SMA) was subjected to AWJ drilling under different machining parameters. The aim of the research is to determine the optimum kerf (K), surface roughness (Ra) and material removal rate (MRR) variables resulting from the drilling process by examining the effect of process variables such as water pressure (WP), stand-off distance (SoD) and feed rate used in AWJ machining of NiTi SMAs. Taguchi-based Gray Relational Analysis (GRA), one of the multi-criteria decision-making methods, was used to optimise machining parameters in the drilling of NiTi SMAs with AWJ. The effect percentages of the test levels in the drilling operations were determined using Analysis of Variance (ANOVA). As a result of the experimental study, optimum levels were obtained for K, MRR and Ra at low WP, medium SoD and high feed rate. According to the result obtained from ANOVA, the parameter with the highest effect on K, MRR and Ra was determined as feed rate with 34.65%.
