무형자산의 중요성이 강조되는 글로벌 경영환경에서 우리나라의 특허 출원은 중국 및 미국, 일본에 이어 4위를 차지하고 있다. 이러한 한국의 특허분야의 위상은 단연 전기/전자/IT산업에 의해 주도되어왔다고 해도 과언이 아니며, 해당 산업에서 특허의 중요성은 더욱 증대되고 있다. 한편 Dahlquist, Robertson(2001)에 따르면 외국인 투자자는 언어 제약 등으로 인해 정보 접근이 제한되어 국내투자자에 비해 국내기업에 대한 정보비대칭이 더 크다. 따라서 국내 전기/전자/IT 기업에 대한 정보가 상대적으로 부족한 외국인 투자자는, 해당 산업에 투자 시 특허의 질적 특성에 대한 정보에 민감하게 반응할 수 있다. 이에 전기/전자/IT산업에서 기업이 보유한 특허의 질적 특성에 대한 외국인 투자자 반응을 실증적으로 분석하였다. 특허의 질적 특성으로는 특허의 중요도 및 기술적·경제적 가치를 반영하는 피인용 빈도와 특허의 법적 권리의 범위를 나타내는 청구항 수를 사용하였고, 특히 기업이 보유하는 다수의 특허 중 스타특허의 질적 특성을 살펴보고자 기업별 최대 피인용 빈도와 최대 청구항수를 변수로 사용하였다. 분석 결과 최대 피인용 빈도와 최대 청구항 수가 많을수록, 외국인 투자 비율이 유의하게 증가하였다. 이러한 결과는 정보비대칭이 높은 외국인 투자자가 우수한 질적 특성을 가진 특허를 보유한 기업에 대한 투자를 선호하는 경향이 있음을 시사한다. 본 연구는 특허 강국으로서의 한국의 위상을 주도해온 전기/전자/IT산업에서 기업이 보유한 특허의 질적 특성에 대해 외국인 투자자가 어떻게 반응하는지를 살펴본 최초의 연구이다. 또한, 본 연구는 외국인 투자자들이 우수한 품질의 특허를 보유한 기업에 대한 투자를 선호한다는 결과를 실증적으로 제시함으로써, 기업의 잠재적 이익과 연계된 혁신활동이 자본시장의 글로벌화에 기여할 수 있음을 시사한다. In a global business environment where the importance of intangible assets is emphasized, Korean patent applications are ranked fourth after China, the United States and Japan. The status of the Korean patent field has been led by the electric/electronic/IT industry, and the importance of patents in the relevant industry is increasing. In particular, foreign investors who have relatively insufficient information on domestic electric/electronic/IT companies may react sensitively to the qualitative characteristics of patents when investing in the relevant industry. Accordingly, the reaction of foreign investors to the qualitative characteristics of patents held by companies in the electric/electronic/IT industry was empirically analyzed. As for the qualitative characteristics of a patent, this paper used the frequency of citations that reflect the importance and technical and economic value of the patent and the number of claims indicating the scope of the legal rights of the patent. To examine, the maximum citation frequency and the maximum number of claims per company were used as variables. As a result of the analysis, the higher the maximum citation frequency and the maximum number of claims, the significantly increased the foreign investment ratio. These results suggest that foreign investors with high information asymmetry tend to prefer investment in companies with patents with excellent quality characteristics. This is the first study to examine how foreign investors respond to the qualitative characteristics of patents held by companies in the electricity/electronics/IT industry, which has led Korea s position as an intellectual property powerhouse. In addition, this study empirically suggested the phenomenon that foreign investors in the electric/electronic/IT industry alleviate information asymmetry and prefer companies with superior quality patent rights.

글로벌 금융위기 이후 이어진 세계 해운산업의 장기침체는 국내 해운기업의 부실위험을 크게 증가시켰다. 우리나라 경제에서 해운산업의 중요성을 고려한다면 개별 해운기업의 위기를 조기에 식별하고 그에 따른 대응방안을 마련하기 위한 부실 예측수단마련이 필수적이라 할 수 있다. 본 연구는 해운기업의 반복되는 위기에 대응하기 위한 위기진단 및 예측모형을 개발하여 제안하고, 장기적인 관리 방향을 설정하고자 하였다. 해운기업의 부실예측을 위해 로짓(logit)모형을 활용하였으며 본 연구에서 고안한 부실예측모형을 통해 실제 법정관리를 신청한 해운기업들을 대상으로 예측력을 검증하였다. 분석결과, 해운기업들이 실제 법정관리를 신청한 시점 이전에 모형의 추정 부실확률이 위기에 대한 신호를 보내는 것을 확인할 수 있어 본 연구의 모형이 해운기업의 부실예측에 도움이 될 수 있다는 것을 확인할 수 있었다. 본 연구를 통해 불확실한 글로벌 해운시장에서 우리나라 해운기업의 리스크를 관리할 수 있는 토대를 마련하였으며 실무적으로도 활용 가능할 것으로 기대된다. Long-term stagnation in the global shipping industry has greatly increased domestic shipping companies’ default risk. Considering the importance of the shipping industry to the Korean economy, the early identification of a crisis in an individual shipping company is essential, to establish a default prediction method that will facilitate preparing necessary countermeasures. The purpose of this study is to develop a crisis diagnosis and prediction model that deals with repetitive crises in shipping companies, and presents a long-term management direction. The Logit Model was used to predict defaults in shipping companies. This study compared default probabilities of companies filing for legal management. The results show that the model’s estimated default probability sent crisis signals to those companies before they filed for court receivership. This confirmed the study’s models could help shipping companies predict possible failure, which lays the foundation for the risk management of Korean shipping companies in an uncertain global market. The practicality of this tool is also expected to be high.

In order to reduce return and disuse of blood components the authors scrutinized the rate of canceled blood components by each department from January to December in 1998 and also estimated the wasted cost for cancelling a unit of blood component. The returned packed red cell was 2,199 units (11.4%) of the released 19,234 units, the returned platelet concentration was 310 units (1.4%) of the released 21,950 units, and returned whole blood were 77 unit (9.4%) of the released 822 units. The returned rate of the packed red cell by the department of chest surgery is 448 units (20.44%) which is the highest, and that by the department of pediatric is 4 units (0.2%) which is the lowest. The returned rate of the platelet concentration by the department of internal medicine is 150 units (48.4%) which is the highest and that by the department of plastic surgery is 23 units (7.4%) which is the lowest. The returned rate of the whole blood was 32 units (48.4%) which is the highest by the department of chest surgery and department of obstetric and gynecology is 3 units (3.9%) which is the lowest. The reason for cancelling blood component is a follow; the patient`s recovery is 2,206 unit (85.3%), the patient`s death is 266 unit (10.3%) and the transfusion reaction is 12 units (0.5%). For the efficient management of insufficient blood resources the doctor should ordered the accurate volume of blood component, and to reduce the rate of return and disuse of blood component the following measures are necessary ; 1) to review and control blood component by the physician in charge along with the clinical pathologist, 2) the more active participation of the transfusion committee 3) to acknowledge of the type & screening test in the medical insurance is needed for the scheduled patient`s transfusion 4) to return of the blood component after release 30 minute is to be inhibited 5) the authors think the continous informing and serious review is very important.

To investigate variation of aerosol number concentration at each different size with three-dimensional (3D) wind components in ocean area, aerosol particles and 3D wind components were measured in the Ieodo Ocean Research Station, which is located to 419 km southwest from Marado, the southernmost island of Korea, from 25 June to & July 2010. The Laser Particle Counter (LPC) and ultrasonic anemometer were used to measure the size of aerosol particles and 3D wind components (zonal (u), meridional (v)), and vertical (w) wind) respectively. Surface weather chart, NCEP/NCAR reanalysis data and sounding data were used to analyze the synoptic condition. The distribution of aerosol number concentration had a large variation from bigger particles more than 1.0μm in diameter by wind direction during precipitation. In the number concentration of aerosol particles with respect to the weather conditions, particles larger than 1.0μm in size were decreased and sustained to the similar concentration at smaller particles during precipitation. The increase in aerosol number concentration was due to the sea-salt particles which was suspended by southwesterly and upward winds. In addition, the aerosol number concentration with vertical wind flow colud be related with the occurrence and increasing mechanism of aerosol in marine boundary layer.

The objective of this study is to evaluate the impact of the high resolution topographies and landuses data on simulated meteorological variables (wind speed at 10 m, temperature at 2 m and relative humidity at 2 m) in WRF. We compare the results with WRF simulation using each resolution of the topographies and landuses, and with 37 AWS observation data on the Seoul metropolitan regions. According to results of using high-resolution topography, WRF model gives better topographical expression over domain. And we can separate more detail (Low intensity residential, high intensity residential, industrial or commercial) using high resolution landuses data. The result shows that simulated temperature and wind speed are generally higher than AWS observation data. However, simulation trend with temperature, wind speed, and relative humidity are similar to observation data. The reason for that is that the high precipitation event occurred in CASE 1 and 2. Temperature have correlation of 0.43~0.47 and standard deviation of 2.12~2.28 ℃ in CASE 1, while correlation of more than 0.8 and standard deviation of 3.05~3.18 m s<SUP>?1</SUP> in CASE 2. In case of wind speed, correlation have lower than 0.5 and Standard Deviation of 1.88~2.34 m s<SUP>?1</SUP> in CASE 1 and 2. In statistical analysis shows that using highest resolution (U01) results are more close to the AWS observation data. It can be concluded that the topographies and landuses are important factor that affect model simulation. However, the tendency to always use high resolution topographies and landuses data appears to be unjustified, and optimal solution depends on the combination of scale effect and mechanisms of dynamic models.
