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.

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.

This study tried to develop a tentative evaluation system on greentourism potentials(GTP) of rural villages. The GTP evaluation system consisted of 45 detail criteria within three kinds of large scale criteria, which are human resources of residents capability, amenity resources of tourists attraction, and income resources through exchange activity between rural and urban areas. The evaluation criteria were adapted from several decades existing studies considering the hardware(facility and amenity resources) and software(human resources and programs on tourism)resources in rural villages. Two kinds of test study areas, which are subdivisions of county in a typical rural area(Boori) and an suburbanized area surrounding a big city(Chooboo), located on Keumsan county in Chungnam province, were selected to test the GTP evaluation system. The results showed that the average GTP values of each village in Boori are higher than those of Chooboo, due to higher values in criteria on amenity resources and income resources, which the typical rural area may have higher value in such criteria.

유기금속화학증착법으로 유리기판 위에 성장된 산화아연 하이브리드 구조의 광학적 전기적 특성

A zinc oxide (ZnO) hybrid structure was successfully fabricated on a glass substrate by metal organic chemical vapor deposition (MOCVD). In-situ growth of a multi-dimensional ZnO hybrid structure was achieved by adjusting the growth temperature to determine the morphologies of either film or nanorods without any catalysts such as Au, Cu, Co, or Sn. The ZnO hybrid structure was composed of one-dimensional (1D) nanorods grown continuously on the two-dimensional (2D) ZnO film. The ZnO film of 2D mode was grown at a relatively low temperature, whereas the ZnO nanorods of 1D mode were grown at a higher temperature. The change of the morphologies of these materials led to improvements of the electrical and optical properties. The ZnO hybrid structure was characterized using various analytical tools. Scanning electron microscopy (SEM) was used to determine the surface morphology of the nanorods, which had grown well on the thin film. The structural characteristics of the polycrystalline ZnO hybrid grown on amorphous glass substrate were investigated by X-ray diffraction (XRD). Hall-effect measurement and a four-point probe were used to characterize the electrical properties. The hybrid structure was shown to be very effective at improving the electrical and the optical properties, decreasing the sheet resistance and the reflectance, and increasing the transmittance via refractive index (RI) engineering. The ZnO hybrid structure grown by MOCVD is very promising for opto-electronic devices as Photoconductive UV Detectors, anti-reflection coatings (ARC), and transparent conductive oxides (TCO).

On a Reduction of Pitch Searching Time by Preliminary Pitch in the CELP Vocoder

Code Excited Linear Prediction(CELP) vocoder exhibits good performance at data rates below 4.8 kbps. The major drawback to CELP type coders is their large amount of computation. In this paper, we propose a new pitch search method that preserves the quality of the CELP vocoder with reduced complexity. The basic idea is to restrict the pitch searching range by estimating the preliminary pitches. Applying the proposed method to the CELP vocoder, we can get approximately 87% complexity reduction in the pitch search. 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. 그 기본 개념은 음성 파형의 예비피치를 찾아내어 피치검색 범위를 제한하는 것이다. CELP 보코더에 제안한 방법을 적용하므로써, 피치검색에서 기존의 방법에 비해 약87%의 복잡성이 감소되었다.

This study aims to estimate the optimal probability distribution of daily electricity generation by wind power, in order to contribute in rural green-village planning. Wind power generation is now being recognized as one of the most popular sources for renewable resources over the country. Although it is also being adapted to rural area for may reasons, it is important to estimate the magnitudes of power outputs with reliable statistical methodologies while applying historical daily wind data, for correct feasibility analysis. In this study, one of the well-known statistical methodology is employed to define the appropriate statistical distributions for monthly power outputs for specific rural areas. The results imply that the assumption of normal distributions for many cases may lead to incorrect decision-making and therefore lead to the unreliable feasibility analysis. Subjective methodology for testing goodness of fit for normal distributions on all the cases in this study, provides possibilities to consider the other various types of statistical distributions for more precise feasibility analysis.
