In this study, priority setting model of new promising IT industries which will be the growth engines for the Korean IT industry, was established. Based on the AHP model, priority setting of IT new promising IT industries was conducted. Firstly, the selection cases of the new promising IT industries and major priority setting methodologies including the AHP methodology, were analyzed. The AHP model was selected as the most feasible methodology for priority setting of the new IT industries, among the various priority setting methodologies. Secondly, in setting up the AHP model for prioritization of the new promising If industries, a 'goal' was established to be priority setting of the new promising IT industries, and an 'alternatives' to be 18 new promising IT industries. Then a logical and a systematic assessment criteria including 5 main criteria('Technological Innovation', 'Market Ability', 'SPin-off Effect', 'Public Benefit', 'Strategic Importance') and 14 sub-criteria, were developed for priority setting of the 18 new promising industries. Finally, with the AHP model, the substantial analysis was made to set up priority of the 18 new promising IT industries. The substantial analysis showed the following priority setting results and implications for the 18 new promising IT industries.

The process of cold rolling is becoming more severe with the increase in the production of high tensile steel strip as a result of increased demand. Consequently, there is a need to develop work roll materials with better resistance to wear and roll failure. DOOSAN has developed an improved in-house 5%Cr alloy, New HSR1, with properties superior to the existing in- house 5%Cr alloy, Old HSR1. Test alloys were designed with controlled amounts of Si and Mn based on Old HSR1 and an optimum alloy was chosen based on thermal shock tests. A prototype work roll was manufactured with New HSR1, and properties of test specimens were evaluated. The results indicated that New HSR1 has better properties than Old HSR1. After application of New HSR1 work rolls, productivity increased due to advanced resistance to wear and roll failure.

IT는 한국의 경제성장에 큰 기여를 해왔으며 사회전반의 패러다임 혁신을 통해 생산성, 효율성, 편의성, 소통성을 증진시키고 삶의 양식에 전면적 변화를 가져왔다. 국민경제와 사회문화에서 지대한 의미를 지나는 IT는 다른 기술 또는 산업과의 융합이라는 새로운 변화와 혁신의 중심에 위치하고 있다. IT융합은 IT의 자체 고도화를 바탕으로 다른 분야의 기술개발과 산업발전을 견인하거나 새로운 산업을 창출하는 것으로 우리나라를 비롯하며 주요국에서는 자원과 역량을 선택적으로 집중하고 있다. 이 논문에서는 IT 융합과 관련된 주요국의 산업 전략 및 기술개발 동향을 파악하고 전문가 설문조사결과를 바탕으로 한국의 IT 융합역량의 수준을 평가하고 결론적으로 IT융합신산업육성 및 선도방안에 관한 전략적 제언을 하고자 한다.

As the size of manufacturing equipment for LCD and OLED displays increases, replacement of existing heavy stainless steel components with light metals, such as aluminum alloys, is being more important in semiconducting and display manufacturing industries. To use aluminum alloys for components in semiconducting and display industries, it is important to develop a new anodization method for improved performance of anodic oxide films than conventional anodization method based on sulfuric acid. In this work, optimum applied current density and the best sealing methods for anodic oxide films in 3% oxalic acid were explored. Experimental results showed 2.5 A/dm2 is the best applied current density for improved hardness and dielectric breakdown voltage. Sealing of the anodic oxide films further improved their hardness, dielectric breakdown voltage and resistance to HCl, by which application of anodic oxide films become applicable for components in semiconducting and display industries.

To provide necessary information for future environmental monitoring of smelting and litharge making industries in Korea, environmental monitoring dataset of air lead concentration of 4 lead industries(1 primary smelting, 2 secondary smelting and 1 litharge making industry) were analyzed from 1994 to 2007. Data were compared using geometric mean and standard deviation with minimum and maximum values according to year of measurement, type of lead industries and type of operation of lead industries. The geometric mean and standard deviation of air concentration for a total of 1140 samples in all lead industries for overall 14 years were 70.7${\mu}g/m^3$ and 5.51 with minimum of 1${\mu}g/m^3$ and maximum of 9,185 ${\mu}g/m^3$. The overall geometric means of air concentration were above the permissible exposure levels(PEL) until year of 2001 and thereafter they were remained at the level of half of PEL. The geometric means of primary smelting, secondary smelting and litharge making industry for overall 14 years were 21.7${\mu}g/m^3$(number of samples: 353), 82.5${\mu}g/m^3$(number of samples: 357) and 164.2 ${\mu}g/m^3$(number of samples: 430) respectively. In primary smelting industry, the highest geometric mean air concentration was 35.4 ${\mu}g/m^3$ in the secondary smelting operation; followed by casting operation (24.9 ${\mu}g/m^3$) and melting operation (14.9 ${\mu}g/m^3$), respectively. On the other hand, in secondary smelting industries, the highest geometric mean air concentration was 125.4${\mu}g/m^3$ in melting operation; followed by casting operation (90.5${\mu}g/m^3$) and pre-treatment operation (43.4${\mu}g/m^3$), respectively. However, in litharge making industries, there were no significant differences of geometric mean air concentrations between litharge operation and stabilizer operation. The proportion of over PEL (50${\mu}g/m^3$) was highest in litharge industry and followed by secondary smelting industries. However The proportions of over PEL(${\mu}g./m^3.$) were decreased by the years of environmental monitoring. The significant reduction of mean air lead concentration since year of 2000 was observed due to more active environmental engineering control and new introduction of new operation in manufacturing process, but may be also influenced by non-engineering method such as reduction of operation hours or reduction of exposure time during actual environmental measurement by industrial hygienist according to more strict enforcement of occupational and safety law by the government.

본 연구는 한국잔디 신품종 '그린에버'(품종보호출원 2014-02)의 특성을 연구하기 위해 수행되었다. '그린에버'는 한국에서 수집한 100개의 자생 한국잔디에서 선발 육종된 품종이며 유전자 분석을 통해 '안양중지', '동래고려지'와 품종의 차별성을 확인하였다(1.48 kb with OPC14 and 1.05 kb with OPD5). '그린에버'의 형태적 특성 평가결과 잔디의 초장($6.8{\pm}0.5cm$), 엽폭($2.0{\pm}0.1mm$), 최하위 엽까지의 높이($1.9{\pm}0.1cm$) 및 종자의 길이($3.0{\pm}0.1mm$) 등은 금잔디의 특성을 띠는 것으로 분류되었으며, 형태적 특성은 '동래고려지'와 유사하였다. 골프장 페어웨이 관리 조건에서 '그린에버'의 잔디 품질, 밀도, 클로로필 등은 '안양중지' 및 '동래고려지' 보다 뛰어난 것으로 조사되었으며 특히 조사기간 동안 그린에버의 밀도는 '안양중지' 및 '동래고려지' 보다 탁월하게 높은 수준을 유지하였다. 향후 '그린에버'의 내한성, 내마모성 등 다양한 환경적응성이 검증된다면 골프장 페어웨이, 티잉그라운드 및 정원 등에 널리 활용될 수 있을 것으로 기대된다.

In construction of new ships and large steel bridges in Korea, pre-construction primers (PCP), also known as shop primer, are routinely used and retained as an integral part of the protective coating system. Retention of PCP's can significantly reduce building schedule and cost. Retaining PCP through the so-called "sweep blasting" procedure eliminates or minimizes the necessity of a second blast operation, thus shortening overall schedule as well as reducing labor cost and hazardous waste disposal cost. This study evaluates the feasibility of retaining PCP as the part of primer for high performance protective coating systems applied to ships' hull, bottom and ballast tanks. Upon proving that the retention of the PCP is a viable option, the process of coating application can he improved significantly in terms of cost and working schedule of new ships and large steel bridges. Results indicate that use of the PCP via sweeping blasting in conjunction with standard high performance protective coating systems does not degrade the overall performance of the coating systems. At the same time, it is also highly recommended that the secondary surface preparation should consist of grit blasting of weld burnt and other damaged areas to SSPC SP-IO grade (Sa 2.5 Gr.), Near White Blast Cleaning with proper application and attention to detail.
