SF<sub>6</sub> is used as an insulating gas because of its excellent electrical insulation properties, non-toxicity, and non-inflammability. On the other hand, the global warming potential of SF<sub>6</sub> is 23,900 times higher than that of CO<sub>2</sub>. The Korea electric power cooperation (KEPCO) is responsible for 80% of the domestic SF<sub>6</sub> usage, and approximately 6,000 tons are currently charged in electrical and power facilities. KEPCO will gradually replace the insulating gas with SF<sub>6</sub>-free gas from 2023. SF<sub>6</sub> decomposition facilities are required because more than 60 tons of SF<sub>6</sub> will need to be disposed of annually from existing equipment. This study developed a novel decomposition and pollution control system that can process 60 tons of SF<sub>6</sub> per year. This facility can decompose more than 97.7% of SF<sub>6</sub>, with the emissions of hazardous and toxic materials below the legal limit.

Purpose: To examine the results of minimal stitch on the restoration of tissue after canalicular laceration. Methods: We have operated using sutures of tissues around canalicular laceration by inserting bicanalicular silicone stents and minimal horizontal mattress sutures with 8-0 Vicryl in cases of canalicular laceration instead of the existing method for the past 6 years. The ages of patients ranged from 2 to 76 years (average age 39.8 ±17.4 years), with most patients in their thirties (12 patients, 40%), 30 cases underwent canalicular repair with minimal stitch and bicanalicular silicone stent insertion within 24 hours after trauma. The silicone stent was removed 3 months after the operation if the patient did not complain of epiphroa while the canalicular remained open. Results: Twenty-five eyes (83.3%) showed symptom improvement and good passage in lacrimal syringing test in 4~12 months (average: 6.8±2.2 months) of follow-up study. Complications included one case each of fistula formation, stent prolapse, and wound infection, and two cases of canalicular stenosis. Conclusions: We recommend this method because of its satisfying success ratio.

Purpose: To report two cases of deepening of the upper lid sulcus following bimatoprost. Methods: A 54-year-old woman who used bimatoprost for one week and a 70-year-old woman who used bimatoprost for 4 months developed deep lid sulcus. Both were using bimatoprost for glaucoma treatment. Results: Both patients also showed improvement of dermatochalasis and widening of the palpebral fissure. One week after discontinuing bimatoprost, the lid sulcus of the 54-year-old returned to baseline and exophthalmometry was unchanged. The orbital CT of the 70-year-old was normal. She did not complain about deepening of the lid sulcus, and she has not discontinued treatment due to this adverse effect.
나노 물질 및 제품의 안전 관리: 윤리적 원리 및 행위지침 고찰
이중원,Lee, Jung-Won 한국진공학회 2010 Applied Science and Convergence Technology Vol.19 No.6
Recently as the reports on toxicity of some nanomaterials and the nanoproducts containing these nanomaterials are rapidly increasing, the safety management issues about nanomaterials and nanoproducts are emerging hot. Especially safety in the workplace and that of consumers and the protection of environment, in other words safeties throughout the life-cycle of nanomaterials and products become core issues. Despite the importance of such a safety management, however, it is very difficult to construct the hard regulatory framework for safety, owing to uncertainties and potentialities of nano-risk. In this paper I will look around the ethical principles and guidelines for safety management which are preferentially required before going into the discussion on the construction of hard-regulation such as law and something like that. Under the circumstance that hard-regulations for safety management are not implementable, these principles and guidelines are expected to play a leading part in building the responsible risk-governance framework for nanomaterials and nanoproducts, and finally to become a cornerstone of the hard risk-governance framework. 최근 나노 물질의 독성에 대한 보고와 나노 물질을 함유한 제품들의 급속한 증가 그리고 제조 과정에서의 나노 물질의 폭 넓은 응용으로 인해, 나노 물질 및 제품의 안전 관리 문제가 중요한 쟁점으로 부상하고 있다. 특히 작업장에서의 안전, 제품을 사용하는 소비자의 안전 그리고 환경 보호 등 나노 물질 및 제품의 전주기 과정에 걸친 안전 확보가 문제다. 하지만 나노 물질 및 제품의 위험이 잠재적이고 불확정적이기에, 이것들을 대상으로 하는 엄격한 안전 관련 규제체계를 구축하는 것은 어렵다. 본 논문에서는 이러한 쟁점들과 관련하여 나노 물질을 연구 개발하고 나노 제품을 생산하는 각 기관들이 안전에 관한 책임 있는 거버넌스(governance)를 구현하기 위해 현재 최선의 것으로 취할 수 있는(엄밀히 말해 취해야 하는) 윤리적인 행위 조치들과 이에 바탕이 되는 윤리적인 원리들을 살펴보고자 한다. 그리고 이것이 법적.제도적인 차원의 견고한 안전관리 체계를 구축하는데 중요한 한 축을 형성함을 강조하고자 한다.

The effects of annealing temperature and time on mechanical properties and microstructures were already investigated in cold drawn pearlitic steel wires. During annealing, the increment of the tensile strength at low temperatures found to be due to age hardening, while the decrease in the tensile strength at high temperatures was attributed to age softening, involving the spheroidization of lamellar cementite and recovery of lamellar ferrite. Since Between increase of tensile strength and the occurrence of the delamination would be closely related to the dissolution of cementite, the increase of drawing strain by lower annealing temperature caused the between higher tensile strength and the easier occurrence of the delamination in cold drawn pearlitic steel wires.

2008년 글로벌 금융위기 이후 유래 없는 저성장과 높은 실업률을 겪으며 과도한 소유권보다는 사용가치를 중시하는 공유경제(Sharing Economy) 개념이 대두되었다. 미국 시장조사기관 매솔루션(Massolution)에 의하면 2010년 8.5억불이던 공유경제 시장 규모는 2014년 100억불 수준으로 4년 사이 1000% 이상 증가했다. 공유경제에 대한 학계의 관심도 높아지고 있다. 하지만 최근 공유경제의 대두배경을 설명할 수 있는 핵심 요소인 IT 플랫폼의 역할에 대한 연구는 미미한 실정이다. 본 연구에서는 공유경제의 기존연구를 바탕으로 공유경제 플랫폼 성과에 영향을 미치는 요인에 대해 연구해 창업자와 연구자들에게 의미 있는 시사점을 제공하고자 한다.
