예금보험(預金保險)과 은행규제(銀行規制)의 필요성(必要性)

김대식,Kim, Dae-Sik 한국재무관리학회 1991 財務管理硏究 Vol.8 No.2

자율화와 경쟁여건의 조성을 통해 금융효율성제고(金融效率性提高)를 추구할 때 금융제도의 안전성과 예금자 보호를 위 한 제도적 장치로서 예금보험제도(預金保險制度)에 대한 고려가 병행되어야 한다. 그러나 은행의 위험에 대한 예금보험제공자와 은행사이에 정보(情報)의 비대칭성(非對稱性)이 존재하기 때문에 공정한 변동보험료제도의 실시가 불가능할 때에는 도덕적 위험문제를 피하기 어렵다는 부작용이 발생한다. 예금보험제도의 유용성을 인정하고 동제도의 목적을 충실히 수행하기 위해서는 도덕적(道德的) 위험(危險)의 억제가 중요하며 그 수단으로 은행규제(銀行規制)가 경제적 타당성을 갖게 된다. 기본적인 규제의 형태로는 적정자본금(適正資本金) 규정(規定), 업무영역(業務領域)의 제한(制限), 탄력적(彈力的)인 수신금리규제(受信金利規制)가 되어야 한다. 현재의 자율화 과정을 고려할 때 규제의 효율성면에서는 위험분담사고에 기초하는 적정자본금 규정이 주된 규제수단이 되어야 할 것으로 고려된다.

In the rapidly changing current society, the Korean National Police(KNP) is facing a lot of demands from the citizens like the protection of subject/victim rights, independence of investigation authority, disclosure of actual truth, and prevention & eradication of crimes. It is widely recognized among the Korean people and the police that the KNP is always standing for the rights of the people and it is high time that the KNP should be restored as the pioneer for the protection of human right. In this situation, the tremendous emphasis is given on the importance of investment in investigative training through the long-term master-plan in order to renovate its constitution, to level up its quality, and to cope with the highly sophisticated crime patterns. Korean police have already shown its outstanding investigative skills of identification of the deceased throughout large cases like Daegu subway arson and tsunami in Southeast Asia. In addition, the skills of cyber crime investigation are highly recognized by foreign law enforcement agencies. However, the investigative skills and abilities are being degraded and the morale of the investigative personnel are falling due to the insufficiently of the finite training budget. Lack of financial support results in the lack of training program and poor training environment, which subsequently leads to the inefficiency of training. Additionally, no long-term budget for fostering specialized investigative agents is allotted. Considering the fact that more than 95% of crimes in Korea are being primarily investigated by the Korean police, we have to understand the importance of the police. By the tremendous investment in investigative training which can lead to the high-quality investigations, the Korean police can ultimately contribute to the protection of safety and life of its people.

In this paper, an automatic cruise system of unmanned boat was developed for surveying water depth in reservoir using GIS (geographic information system)-GPS (global positioning system) Technologies. the automatic cruise system consisted of an automatic path generation program (APGP) and an automatic boat control program (ABCP). A grid processing method with $3{\times}3$ roving window in GIS function was used to develop the APGP. For development of the ABCP, GPS and its coordinate calculation technique were introduced. The developed system was tested to verify the applicability for a sample reservoir, Misan reservoir located on Ansan city of Kyunggi province. From the test results, this study found the APGP generated cruise path automatically according to input condition on grid size of 5 m, 10 m, and 20 m, as well as, the ABCP also tracked well the cruise paths with high position accuracy. Another verification result on surveying time for 20 ha of water area also showed that the new system could survey water depth of reservoir quickly, including very high quality of spatial resolution.

부호여기된 선형예측(CELP) 음성부호화기는 4.8 kbps 이하의 낮은 전송 비율에서도 좋은 성능을 갖는다. CELP형 부호기의 단점은 많은 계산량을 필요로 한다는 것이다. 본 논문에서, 우리는 복잡성을 줄이면서 CELP 보코더의 음질을 유지하는 새로운 피치 검색법을 제안하였다. 이것은 음성 파형의 자기상관계를 간단한 전처리관계식에 의해 사전에 파악하여 필요한 구간에 대해서만 피치검색을 수행하는 방법이다. 제안한 방법은 피치검색에서 기존의 방법에 비해 약 $77\%$의 복잡성이 감소되었다. Code Excited Linear Prediction(CELP) speech coders exhibit good performance at data rates below 4.8 kbps. This major drawback of CELP type coders is required much computation. In this paper, we propose a new pitch search method that preserves the quality of the CELP vocoder with reducing complexity. In the pitch searching, we detect the segments of high correlation by a simple preprocessing, and then carry out the pitch searching only for the segments obtained by the preprocessing. By using the proposed method, we can get approximately $77\%$ complexity reduction in the pitch search.

김대식,남상운,김태철,Kim, Dae-Sik,Nam, Sang-Woon,Kim, Tai-Cheol 한국농공학회 2008 한국농공학회논문집 Vol.50 No.5

This study aims to simulate the 3 dimensional (3D) model of Keum-man connection canal using geographic information system (GIS) as well as considering design in viewpoint of engineering. The canal connects from Keumkang to Mangyungkang in order to supply fresh water into Saemankeum lake. This study used 3 dimensional spatial planning model (3DSPLAM) process to generate the 3D model, which has not only several planning layers in actual process, but also their corresponding layers in modeling process to simulate 3D space of rural villages. The discharge of the canal is $20m^3/s$ on slope of 1/28,400 in the canal length of 14.2km, which consists of pipe line and open channel. This study surveyed the route of the canal and its surrounding environment for facilities to make images in the 3D graphic model. Besides, the present study developed data set in GIS for geogrphical surface modeling as well as parameters in hydraulic analysis for water surface profile on the canal using HEC-RAS model. From the data set constructed, this study performed analysis of water surface profile with HEC-RAS, generation of digital elevation model (DEM) and 3D objects, design of the canal section and route on DEM in AutoCAD, and 3D canal model and its surrounding 3D space in 3DMAX with virtual reality. The study result showed that the process making 3D canal model tried in this study is very useful to generate computer graphic model with the designed canal on the surface of DEM. The generated 3D canal can be used to assist decision support for the canal policy.

김대식,임정빈,Kim, Dae-Sik,Yim, Jeong-Bin 해양환경안전학회 2016 海洋環境安全學會誌 Vol.22 No.1

본 연구는 인적오류 예방을 위해 선박 충돌위험 가능성이 높은 여섯 가지 선박조우상황(Head on, $045^{\circ}$, $090^{\circ}$, $135^{\circ}$, Overtaking, Overtaken)에 대해서 양 선박의 거리가 점차 감소될 때 항해 당직자가 느끼는 충돌위기체감지수(Collision Risk Perception Index, CRPI)를 획득하고 통계분석을 통하여 신뢰도분석 및 가설을 검증한 후 곡선근사과정을 통해 다항 계수로 모델링하는 것이 목적이다. 해상에서 실제 경비함 두 척과 항해당직 승조원 총 30명을 대상으로 CRPI 데이터 획득 실험을 하였으며 데이터 분석결과 각 조우상황에서 높은 신뢰도를 나타냈고 유의미한 결과를 나타냈다. 또한 타 선박 조우시 양 선박간 거리가 가까워지는 상황에서 항해당직자의 승선경력과 연령이 많고, 상위면허를 보유 할수록 CRPI에 음(-)의 영향을 미친다는 것을 알았다. 또한 3차 다항식 모델로 CRPI를 추정한 결과 평균제곱오차(RMSE)는 Head on에서 1.19, $045^{\circ}$에서 0.87, $090^{\circ}$에서 0.81, $135^{\circ}$에서 0.71, Overtaking에서 1.29, Overtaken에서 0.87로 나타나서 CRPI 곡선근사가 유용함을 알았다. The purpose of this study is for Human error prevention to acquire Collision Risk Perception Index (CRPI) sensed by the Officer Of the Watch (OOW) when the approaching distances are reduced in six types of ship encountering situations (Head on, $045^{\circ}$, $090^{\circ}$, $135^{\circ}$, Overtaking, Overtaken) between own ship and a target ship and then to predict CRPI fitting coefficients with polynomials in the curve-fitting process. CRPI acquisition experiments are carried out on two coast-guard ships and with the total of 30 crew members. Analysing results shows that CRPI data have goodness of fit to the six types of encountering situation. Futhermore, the One-Way ANOVA results show that CRPI has a negative affect to the OOW's age, career and license grade as the approaching distances is reduced. The availability of CRPI curve fitting with 3 degrees of polynomial was testified through the RMSE as 1.19 to Head on, 0.87 to $045^{\circ}$, 0.81 to $090^{\circ}$, 0.71 to $135^{\circ}$, 1.29 to Overtaking and 0.87 to Overtaken.
