Corruption is a serious political factor that distorts economic structure and slows economic development. In particular, the transition to the market opening economy increases the corruption incentives due to the transitional situation. The purpose of this study is to investigate the influencing factors on corruption using 2013 Myanmar Enterprise Survey data provided by World Bank. As a result of the analysis, it was found that the manager 's willingness to dealing the regulation and the necessity of licensing had a positive relationship with corruption at the level of 90% and 95%, respectively. In the competitive environment factor, the intensity of the competition showed a significant increase at the level of 90%. In the institutional environment, the perception of social corruption and the obstacle of the taxation authorities increased the corruption. On the other hand, the increase in the instability of the political environment and strict enforcement of laws has been shown to reduce corruption. However, there was no significant relationship between managerial capacity, corruption of competitors, tax rate, and administrative environment.

임헌진,이홍림 한국세라믹학회 1989 한국세라믹학회지 Vol.26 No.5

Beta-sialon powder(Z=1) was synthesized by the simultaeous reduction and nitridation of the mixed powders of Hadong kaolin and silica. Silicon hydroxide was prepared from Si-alkoxide by a hydrolysis method and amorphous silica was obtained from the calcination of the prepared silicon hydroxide. Hadong kaolin was mixed with both the silicon hydroxide and amorphous silica, respectively. The average particle size was 4${\mu}{\textrm}{m}$ and the morphology of particle was rod-like and equiaxed in the case of beta-sialon powder prepared form Hadong kaolin and silicon hydroxide(COMPOSITION A), whereas the average particle size was 3${\mu}{\textrm}{m}$ and the morphology of particle was equiaxed in the case of beta-sialon powder prepared from Hadong kaolin and amorphous silica(COMPOSITION B). The synthesized beta-sialon powders were hot-pressed at 175$0^{\circ}C$ for 2 hours under 30 MPa in a nitrogen atmosphere after YAG composition(8wt%) was added to these powders as a sintering agent. The hot-pressed specimens were annealed a 140$0^{\circ}C$ for 4 hours in a nitrogen atmosphere. The mechanical properties of sintered bodies were investigated in terms of M.O.R., fracture toughness and hardness. The measured values are as follows. COMPOSITION A : M.O.R. 508MPa, KIC 3.5MN/m3/2, hardness 13.6GPa. COMPOSITION B : M.O.R. 653MPa, KIC 5.4MN/m3/2, hardness 13.5GPa.

알루미나 세라믹스의 기계적 특성 평가

임헌진,조덕호,김무경,한상미,이와사미키오 한국세라믹학회 1996 한국세라믹학회지 Vol.33 No.3

알루미나를 대상소재로 하여 국산 3종 및 일산 1종의 고순도 알루미나 제품을 구입하여 꺾임강도, 비커스 경도, 압자압입법 및 압입강도법에 의한 파괴인성 등의 기계적 물성을 평가하였다. 꺾임강도 및 와이블 계수는 제조회사에 따라 각각 약 300~400MPa, 5~15의 범위에서 큰 편차를 나타내었다. 압입하중 변화에 따른 경도시험시 탄성회복의 영향을 무시할 수 있는 임계하중은 약 9.8N이었으며, 압입하중 98N에서의 알루미나의 경도는 약 15GPa이었다. 파괴인성은 한 압입하중에서의 측정한 평균값으로 파괴인성을 구하는 것보다 압자압입법의 경우 압입하중과 균열길이, 압입강도법의 경우 압입하중과 꺾임강도와 관계식의 기울기로부터 각각 직선회기법으로 파괴인성을 구하는 것이 보다 신뢰성이 있으며, 알루미나의 파괴인성은 약 4 MPa·m1/2이었다. Mechanical properties(flexural strength hardness fracture toughness) of alumina ceramics were evaluated. Alumina products of four companies were selected and three of those were made in Korea and one of those was made in Japan. The large differences according to manufacturing companies had resulted from flexural strength and weibull modulus which had a wide ranges of 300 to 400 MPa and 5 to 15 respectively. Critical indenstation load which could be neglected the effect of elastic recovery was about 9.8N and Vickers' hardness were about 15 GPa. Fracture toughnesses were evaluated by IF and ISB method. It was more preferable to the average at one indentation load that fracture toughness were obtained from the slope of the relationship between indentation load and crack length in IF method and between indentation load and fracture load in ISB method and fracture toughness was about 4 MPa·m1/2.

This study delivers the actual condition of investment for industrial accident prevention based on survey of 526 construction sites. The various research techniques were used such as technical statistic analysis for construction industry, construction and civil engineering works, cost comparison of industrial accident prevention and accident loss. A formula was deduced to calculate accident loss and accident frequency by accident prevention cost through regression analysis.

선박평형수 내 고농도 총 잔류 산화물(Total Residual Oxidant) 분석이 가능한 DPD TRO Sensing 시스템 개발 가능성 평가

임헌진,이광호,황옥명,최규성,류관현,권재형 대한환경공학회 2019 대한환경공학회지 Vol.41 No.1

DPD TRO sensor for measuring high concentration range (above 10 mg/L) of total residual oxidant which is an index for disinfection and neutralization in ballast water has been constructed. The results of absorbance test using RGB sensor show two times higher separated performance in high concentration of TRO at 460~480 nm wavelengths (blue ray zone) than 510~520 nm wavelengths (green ray zone) which is used in existing DPD sensor. As a result of reagent porformance test in order to apply in ballast treatment system, the mixing ratio of buffer reagents (Ethylene diamine tetra acetic acid, potassion iodide, (Tri)sodium Citrate Salt) which is 5 : 30 : 65 is the best mixing combination of DPD reagents in accordance with the public announcement on the type approval and precision test of the environmental measuring devices. 고농도 TRO (10 mg/L 이상)분석이 가능한 DPD TRO sensing system 개발을 통한 선박평형수의 살균 및 중화배출 기준이 되는 총 잔류 산화물(TRO)의 농도분석 적용 가능성을 검토하였다. RGB 센서를 이용한 흡광도 분석결과 기존의 DPD sensor의 흡수파장 구간인 510~520 nm(녹색파장)보다 460~480 nm(청색파장) 구간에서 고농도 TRO 분리능이 2배 이상 높음을 알 수 있었다. DPD TRO sensing system에 적용하기 위한 reagent 성능평가를 진행한 결과 buffer reagent (Ethylene diamine tetra acetic acid, potassion iodide, (Tri)sodium Citrate Salt) 배합비율이 5 : 30 : 65 조건에서 환경측정기기의 형식승인, 정도검사등에 관한 고시의 기준(정확도: 5% 이하, 정밀도 2% 이하)에 만족하는 최적의 성능을 구현함을 확인할 수 있었다.

X-선 형광분석법에 의한 포틀란드 시멘트의 정량분석

임헌진,백연봉,김도생,윤준수,이경원 한국세라믹학회 1996 한국세라믹학회지 Vol.33 No.8

X-선 형광분석법을 사용하여 표준검정곡선법으로 시멘트 중의 주, 부성분들을 정량하고 습식법과 분석결과를 비교하였다. 이때, 표준시료 및 미지시료는 용융 케스트 비드법으로 준비하였다. 표준시멘트(227A372)의 오차분석결과 주성분인 CaO, SiO2, Al2O3, Fe2O3 및 부성분중의 MgO, SrO는 상대오차가 1% 이내이었으며, 부성분중 So3, K2O, TiO2, Na2O P2O5 및 Mn2O3는 5% 이하의 상대오차를 가졌다. 부성분의 상대오차는 시료준비오차가 가장 큰 부분을 차지하였다. X-선 형광분석과 습식분석을 비교한 결과 시멘트 분석의 측정값간의 최대혀용범위를 만족하므로, X-선 형광분석법을 시멘트 화학분석에 적용할 수 있을 것으로 판단된다. 그리고, 기존의 습식법으로 분석하기 어려운 시멘트내에 존재하는 미량성분인 P2O5, SrO 및 Mn2O3 의 정밀정확한 분석 또한 가능하였다. Quantitative analysis each portland cement components was conducted by standard calibration method using X-ray fluorescence spectrometer. Standard sample and the unknown sample were prepared by fused cast bead method. In checking the errors of standard cement 227A372 the relative errors of constituents such as CaO, SiO2, Al2O3, Fe2O3, MgO and SrO were less than 1% and the relative errors of constituents such as So3, K2O, TiO2, Na2O P2O5, and Mn2O3 were less than 5% Sample preparation was mainly contributed to the errors. Compared with general wet chemical method the results of X-ray fluorescence analyses were more precise and accurate. Moreover it is possible to analyze precisely a little amount of the constituents such as SrO, Mn2O3 and P2O5 the analyses of which were very difficult using the wet chemical method.
