The current gas regulations have been reformed into a new technical standards system called as "KGS (Korea Gas Safety) Code" system. Korea Gas Safety Corporation has developed a new framework of technical standards classification method and will manage the new technical standards system in compliance with the mandatory requirements of gas regulations. This study will cover an overall view of the reformation and show "KGS Code" in detail.

Education and training of technical staff for the new generation technological equipment has a vital importance for developing countries in order to maintain sustainable development and keep up with new generation technologies. Mechatronics the synergistic combination of mechanical, electronic and software engineering from an engineering perspective to serve the purposes of controlling advanced hybrid systems is a product of new generation technology which can be given as a sample to this phenomenon. Recent marine engines are combination of heavy industry with high technology. Nowadays, ships are built in full automation and equipped with computer controlled mechatronics systems. However, finding qualified officer and engineers who can operate, maintain, control and repair when it is required such full automatic systems with knowledge of a new generation system became a serious issue. Due to importance of this fact STCW Manila amendment has new training and certification requirements for electro-technical officers. In this paper, Mechatronics applications on ship are introduced, importance of it highlighted and a new syllabus is proposed for the training of marine engineers to be nurtured with mechatronics knowledge as it is required.

Background/Aims: Situs inversus viscerum (SIV) is a congenital condition defined by left-to-right transposition of all visceral organs. This anatomical variant has caused technical challenges in endoscopic retrograde cholangiopancreatography (ERCP). Data on ERCP in patients with SIV are limited to case reports of unknown clinical and technical success rates. This study aimed to evaluate the clinical and technical success rates of ERCP in patients with SIV. Methods: Data from patients with SIV who underwent ERCP were retrospectively reviewed. The data were collected by querying the nationwide Veterans Affairs Health System database for patients diagnosed with SIV who underwent ERCP. Patient demographics and procedural characteristics were collected. Results: Eight patients with SIV who underwent ERCP were included. Choledocholithiasis was the most common indication for ERCP (62.5%). The technical success rate was 63%. Subsequent ERCP with interventional radiology-assisted rendezvous has increased the technical success rate to 100%. Clinical success was achieved in 63% of cases. Among cases of subsequent rendezvous ERCP after conventional ERCP failure, clinical success was achieved in 100%. Conclusions: The clinical and technical success rates of ERCP in patients with SIV were both 63%. In patients with SIV in whom ERCP fails, interventional radiology-assisted rendezvous ERCP can be considered.

The aim of this study was to examine whether near infrared spectroscopy (NIRS) is an acceptable tool to determine cholesterol and collagen in human atherosclerotic plaque without destruction of the analyzed areas and without danger the endothelial cells - three preconditions for the development of a NIR-heart-catheter. The questions were: Can the cholesterol and collagen content of the arterial intima be estimated with acceptable precision in vitro by NIRS despite the matrix inhomogeneity of the plaques and their anatomic variability\ulcorner How deep can such NIR radiation penetrate into arterial tissue without danger for endothelial cells\ulcorner Is this penetration sufficient for information on the lipid and collagen accumulation\ulcorner Using NIRS, cholesterol and collagen can be determined with acceptable precision in model mixtures and human aortic specimens (r=0,896 to 0,957). The chemical reference method was HPLC. The energy dose was 71 mW/$cm^{-2}$ using a fiber optic strand with a length of 1.5m and an optical window of d=4mm. This dose appears to be not dangerous for endothelial cells, It will be attenuated to 50% by a arterial tissue of about 170-$200\mu\textrm{m}$ thickness. The results are also acceptable using a thin coronary catheter-like fiber optic strand (d=1mm).

Purpose: The gastrointestinal system is the most commonly affected organ, followed by the lungs, in patients with primary immunodeficiency disease (PID). Hence, it is common for children with PIDs to present with gastrointestinal symptoms. We aimed to analyze the clinical and histopathological findings of patients who were initially admitted to pediatric gastroenterology/hepatology clinics and subsequently diagnosed with PIDs to identify the clinical clues for PIDs. Methods: The demographic, laboratory, and histopathological findings, treatment modality, and outcomes of patients initially admitted to the pediatric gastroenterology/hepatology unit and subsequently diagnosed with PIDs were recorded. Results: The study included 24 patients (58.3% male; median age [range]: 29 [0.5-204] months). Common clinical presentations included chronic diarrhea (n=8), colitis (n=6), acute hepatitis (n=4), and acute liver failure (n=2). The association of autoimmune diseases, development of malignant diseases, and severe progression of viral diseases was observed in 20.8%, 8.3%, and 16.6% of the patients, respectively. Antibody deficiency was predominantly diagnosed in 29.2% of patients, combined immunodeficiency in 20.8%, immune dysregulation in 12.5%, defects in intrinsic and innate immunity in 4.2%, autoinflammatory disorders in 8.3%, and congenital defects of phagocytes in 4.2%. Five patients remained unclassified (20.8%). Conclusion: Patients with PIDs may initially experience gastrointestinal or liver problems. It is recommended that the association of autoimmune or malignant diseases or severe progression of viral diseases provide pediatric gastroenterologists some suspicion of PIDs. After screening using basic laboratory tests, genetic analysis is mandatory for a definitive diagnosis.

The purpose of this study is 1) to research how practitioners in fashion industry in South Korea perceive concepts of Technical Design/Designer, 2) to compare and analyze issues at work by occupation, 3) to research specific works in garment development process, and 4) to compare and analyze work involvement by occupation, type of a company and etc, and 5) to propose the role of Technical Designers in apparel companies in South Korea. There were two methods to conduct this study, which were in-depth interview and survey. Both methods were conducted to designers, merchandisers, pattern makers, technical designers, and production coordinators. Frequency analysis, ANOVA, Duncan test, and Factor analysis were performed to get results by using SPSS 18.0 program. The results are following. There were 50 works during garment development process from the result of in-depth interview, and 6 factors were obtained from the result of Factor analysis, which were 'Works about Sample in Sample Development Process', 'Works about Product's Pattern and Size Spec', 'Works about Development of Garment's Design', 'Works about Planning of Product Development and Management of Product in Stock', 'Works about Production Process', and 'Preparation Works for Sample Development'. In conclusion, technical designer in apparel companies in South Korea should be in charge of works about sample in sample development process and decision making of product' size spec, which is included in works about product's pattern and size spec. Also, they should complete technical package after product is developed by designers.
