Purpose: To compare the intraoperative and postoperative complication rates and visual outcomes with M2 130 head (thick flap group) and M2 110 head (thin flap group). Methods: One-hundred-ninety-five eyes of 104 patients who underwent LASIK with the Moria M2 microkeratome and Allegretto-wave laser were reviewed retrospectively. Selection of M2 heads was based on preoperative pachymetry and estimated ablation depth. Intraoperative and postoperative flap-related complications, mean postoperative uncorrected visual acuity (UCVA), and mean spherical equivalent (MSE) were evaluated and compared. Results: Mean follow-up was 8.1 months. The number of eyes, preoperative MSE and mean corneal thickness of M2 130 were 115, -4.04±1.63diopter (D) and 549.40±39.16??m, and 85, -6.61±3.43D and 525.16±24.53 ?m, respectively, in the 110 head group. Mean UCVA and MSE at postoperative 1 week, 3 months and 6 months were 1.00±0.18, -0.26±0.49D; 1.07±0.68, -0.40±0.51D; and 1.01±0.22, -0.51±0.50D, respectively, in the 130 head group, and 0.90±0.23, -0.46±1.02D; 0.91±0.23, -0.67±0.79D; 0.85±0.46, -0.75±0.88D, respectively, in the 110 head group. There were no significant differences in intraoperative and postoperative flap-related complication rates between the two groups (p=0.316). There were no statistically significant differences in postoperative mean UCVA or MSE between the two groups (p>0.05), except for MSE at the third and sixth postoperative months (p=0.005, 0.013). Conclusions: Proper selection of M2 heads by preoperative pachymetry allowed for an adequate residual stroma bed with good visual outcome. Utilizing one single microkeratome and switching between two heads was advantageous and cost-effective.

토공사 환경오염물질 부하량 및 공사비를 이용한 장비조합방법 연구

강민호,박형근,Kang, Min-Ho,Park, Hyung-Keun 대한토목학회 2013 대한토목학회논문집 Vol.33 No.3

1997년 "기후 변화에 관한 국제연합 규약의 교토의정서"가 채택된 이후 우리나라를 비롯한 세계의 여러 나라에서 이산화탄소를 포함한 온실가스 배출을 줄이기 위한 노력을 진행해 왔다. 각 산업별로 온실가스 배출을 저감시키는 산업 구조로 개편 및 녹색 기업으로 체질 개선에 힘쓰고 있으나 타 산업에 비하여 건설 산업은 온실가스 배출의 효율적인 관리를 위한 정확한 배출량 저감을 위한 논의가 미흡한 상황이며 오히려 환경을 파괴시키는 산업이라는 오명을 가지고 있는 실정이다. 우리나라는 경제규모에 비해 환경오염물질 배출량이 많으며 이는 에너지 다소비 업종의 비중 증가에 따른 것이다. 이에 따라 에너지 다소비업종 중 하나인 건설관련 공사에 대한 효율적인 에너지 절약이 이루어지지 않은 문제점이 대두되고 있다. 뿐만 아니라 근래에는 대규모 건설이 많으므로 에너지 절감효과를 갖기 위해서는 건설공사의 전과정(Life Cycle) 중 시공단계에서 발생하는 에너지소비량, 환경오염물질 배출량, 환경비용 등 기본적인 데이터베이스 및 활용방안 개발이 필요하다. 그러나 건설현장 특성상 정량화가 어렵다는 이유 등으로 친환경 건설에 관한 연구는 대부분 구조물 사용 및 유지 보수 단계에 집중되어 있다. 이에 본 연구에서는 지식경제부와 환경부에서 제시하는 LCI DB를 활용하여 굴착작업 시 발생하는 환경오염물질 배출량을 산출하고 환경오염물질별 환경비용을 환산하여 토공사에 대한 환경경제성을 평가하고자 한다. Great efforts have been made worldwide to reduce the Green House Gas (GHG) emission following the "Kyoto Protocol" declared during the United Nations Framework Convention on Climate Change in 1997. Many industries have restructured to meet the standard set by the Protocol. However, no clear guidance has been established for the purpose of reducing the GHG emission in construction industry. In addition, no significant effort has been made to conserve the energy during construction activities. For more effective energy saving in construction industry, it is essential to collect data about energy consumption, quantity of environmental emissions and costs. However, most studies on sustainable construction have been concentrated on the use of equipment, maintenance and repair works during construction due to the difficulties of collecting such data. This study suggests a method to select the most environmentally friendly equipment combination for earthwork with comparing environmental loads and costs using the database of Life Cycle Inventory in the Ministry of Knowledge Economy and Ministry of Environment of Korea.

Purpose: This study was designed to determine which sensory test best reflects the improvement of binocular function according to the surgical outcome of intermittent exotropia Methods: We examined the visual acuity, refractive error, angle of exodeviation, fusional status with the Worth-4-dot, Bagolini tests and stereoacuity with the Titmus test preoperatively in 61 intermittent exodeviation patients who had undergone the bilateral lateral rectus recession operation from February 2002 to 2003 July. We compared the binocularity tests between the two groups: esodeviated and orthotropic or exodeviated. Results: The average improvement time of the Bagolini, Worth 4 dot and Titmus tests was 0.54±1.2, 2.03±2.90, 1.12±2.1 weeks, respectively. Although the shortest time was for the Bagolini test (p=0.001), the Titmus test was more sensitive. Conclusions: The high variability of the binocularity tests should be remembered and take into account when we interpret the test results.

파산법원 설치에 따른 회생 · 파산절차 관여자에 대한 적정한 관리 · 감독 방안에 관한 연구

In order to secure the integrity and expertise of insolvency representatives who, along with the court, play crucial roles in insolvency proceedings, these proceedings place emphasis on insolvency representatives’ qualifications and have a system of managing and supervising their conduct. The establishment of the bankruptcy court is driven by, and pursuant to, the demands both inside and outside the court for specialized handling of insolvency cases. In order for the bankruptcy court to successfully establish itself as a specialized court running insolvency proceedings fairly and efficiently, the kind of foundation to be laid in the management and supervision of insolvency representatives must be examined. Proper management and supervision of insolvency representatives requires fair election of qualified insolvency representatives, securing of judges’ and court officials’ expertise, strengthening of Bankruptcy administration committee’s management and supervision functions, and facilitating of creditors’ (or a creditor committee’s) participation in the proceedings, through efficient assigning of roles among those managing and supervising insolvency representatives and securing of human, physical and systemic foundations.

본 연구에서는 SWASH 모형을 이용하여 계절별 이상파랑에 의한 해운대 해수욕장에서 불규칙파의 파랑변형 및 해빈류 특성을 분석하였다. 개경계에서 불규칙파는 JONSWAP 스펙트럼을 적용하였다. 입사파 조건은 국립해양조사원에서 제공하는 2014년 파랑관측자료를 바탕으로 계절별 대표파를 선정하였다. SWASH에 의한 계절별 해빈류 계산결과는 현장조사 결과와 비교·검토하였다. 하계의 경우 S 계열의 파랑이 지배적이며 동백섬측에서 미포측으로 연안류가 지배적으로 발생하였고 해운대 해수욕장 중앙부근에서는 이안류가 발생하였다. 동계의 경우 ESE 계열의 파랑이 지배적이며 해운대 해수욕장 중앙부근에서 각각 동백섬측과 미포측으로 향하는 연안류가 발생하였다. To simulate a complicated hydrodynamic phenomena in the surf zone, the SWASH model is used in Haeundae Beach. The SWASH model is well known as a model competing with the Boussinesq-type model in terms of near shore waves and wave-induced currents modelling. This study is aimed to the detailed analysis of seasonal waves and wave-induced current simulation in Haeundae Beach, where the representative seasonal wave conditions was obtained from hourly measured wave data in 2014 by Korea Hydrographic and Oceanographic Administration(KHOA). Incident wave conditions were given as irregular waves by JONSWAP spectrum. The calculated seasonal wave-induced current patterns were compared with the field observation data. In summer season, a dominant longshore current toward the east of the beach appears due to the effect of incident waves from the South and the bottom bathymetry, then some rip currents occurs at the central part of the beach. In the winter season, ESE incident waves generates a strong westward longshore currents. However, a weak eastward longshore currents appears at the restricted east side areas of the beach.

In the HVDC Cable Accessory connection, there are a lot of space charges at the interface between the cable insulation and the connection part insulation, and at the interface between metals and polymers. It is also reported that insulation and accessory insulation have a large difference between the ratio of the dielectric constant and electrical conductivity of the cable and accessory insulation. And this space charge can strengthen and distort the local electric field near the interface. For that reason, the surface of SiC (Silicon Carbide), a semiconductive inorganic material based on EPDM (ethylene propylene diene terpolymer), was modified to strengthen the chemical reaction and interface. EPDM/Nano SiC/Micro SiC Mixture Composites were prepared and the properties of electrical insulation, electrical conductivity, and thermal conductivity were studied by mixing nano SiC and micro SiC.Moreover, in order to increase the mechanical tensile strength in the optimal state of electrical conduction and electrical insulation, the electrical and mechanical properties were studied by mixing Akitifit (Silica Kolinite), a surface-modified inorganic material.
