In this study, we report the summary characteristics of CEOs of SI firms in Korea. In the first part of our paper, age, educational background, and career of CEOs in SI firms are analyzed according to CEO types (owners versus professional managers). In the second part, CEO tenures of Si firms in Korea are compared with those in the U.S. and Japan. We found that CEO tenures of SI firms in Korea are remarkably shorter than those in the U.S. and Japan. In conclusion, we contend that CEO systems in Korean firms should be improved to guarantee the longer tenures especially for professional managers.

In the wake of several high-profile corporate accounting scandals, there has been evidence that companies are more eager to hire Chief Executive Officers (CEOs) with an accounting background. This signals that CEOs with an accounting background are recognized and trusted by the corporate world to boost the quality of financial reporting of a company. If it is so, in the context of combating the earnings management, hiring CEOs with an accounting background (being a conservative accounting practitioner), could become one of the effective internal corporate governance mechanisms (CGM) to bring down the earnings management activities. This study attempts to provide insight into the level of conservatism of the CEO with an accounting background. Following Basu (1997) and Khan and Watt (2009), the firm-year measure of conservatism (C_Score) was obtained, which later was associated with the accounting education of the CEO to determine their relationship. As expected, CEOs with accounting background exhibit a higher level of moral reasoning than their non - accounting educated counterparts. The finding of this study is useful to persuade the policymaker to consider lifting the trend of hiring a CEO with an accounting background as one of the best practices that the companies can work out to lessen earnings management activities.

이 논문은 지역방송 내부 식민지화의 중심에 사장선임을 위시한 지배구조가 자리하고 있다는 데 주목했다. 그 실체를 파악하기 위해 1990년대 중반에서 2015년 사이 MBC 지역계열사 17개사와 지역민방 9개사, 총 26개 지역방송사의 사장과 주주 이사 구성을 취합 분석했다. 이와 함께 지역방송 인력과 운영현황, 그리고 그 문제점을 검토 논의했다. 이를 통해 지역방송의 내부 식민지화가 작동하는 방식을 규명했다. 지역MBC는 서울본사의 필요를 우선순위에 둔 지배구조가, 지역민방은 소유와 경영 분리 미흡에 따른 대주주의 전횡이 제작과 인력 부문의 투자 제약요소로 작용하면서 내부 식민지화가 가동되고 있었다. 이어 이 논문은 지역방송 사장선임을 비롯한 지배구조 개선방향을 법 제도와 방송사 자율규제 차원에서 제안했다. 법 제도적으로는 방송법상의 지역방송 편성규약 단서조항 신설을 비롯해 관련법령인 지역방송발전지원특별법, 방송광고판매대행 등에 관한 법률, 방송통신위원회의 설치 및 운영에 관한 법률 개정안을 구체적으로 제시했다. 자율규제로는 지역MBC의 경우 사장선임추천위원회 운용과 방송문화진흥회 이사의 3분의 1을 지역인사로 구성하는 방안, 지역민방은 소유와 경영의 분리를 출발점으로 한 공공성 회복과 사장 사외이사추천위원회 도입 등을 제안했다.

Brillouin backscatter is a type of reflection that occurs when light is shone into an optical fibre. Brillouin reflections are very sensitive to changes in the fibre arising from external effects, such as temperature, strain and pressure. We report here several case studies on the measurement of strain using Brillouin reflections. A mechanical bending test of an I beam, deployed with both fiber optic sensors and conventional strain gauge rosettes, was performed with the aim of evaluating: (1) the capability and technical limit of the DTSS technology for strain profile sensing; (2) the reliability of strain measurement using fiber optic sensor. The average values of strains obtained from both DTSS and strain gauges (corresponding to the deflection of I beam) showed a linear relationship and an excellent one-to-one match. A practical application of DTSS technology as an early warning system for land sliding or subsidence was examined through a field test at a hillside. Extremely strong, lightweight, rugged, survivable tight-buffered cables, designed for optimal strain transfer to the fibre, were used and clamped on the subsurface at a depth of about 50cm. It was proved that DTSS measurements could detect the exact position and the progress of strain changes induced by land sliding and subsidence. We also carried out the first ever distributed dynamic strain measurement (10Hz) on the Korean Train eXpress(KTX) railway track in Daejeon, Korea. The aim was to analyse the integrity of a section of track that had recently been repaired. The Sensornet DTSS was used to monitor this 85m section of track while a KTX train passed over. In the repaired section the strain increases to levels of 90 microstrain, whereas in the section of regular track the strain is in the region of 30-50 microstrain. The results were excellent since they demonstrate that the DTSS is able to measure small, dynamic changes in strain in rails during normal operating conditions. The current 10km range of the DTSS creates a potential to monitor the integrity of large lengths of track, and especially higher risk sections such as bridges, repaired track and areas at risk of subsidence.
