통합물관리 (IWRM; Integrated Water Resources Management)란 생태계의 지속가능성(sustainability)을 해치지 않으면서, 공평한 방법(equity)으로 경제·사회·복지를 극대화(efficiency) 할 수 있도록 물과 토지 및 관련 기타 자원들을 조화롭게 개발하고 처리하는 과정을 말한다. IWRM 패러다임은 전 세계적 및 국가별 물관리 상황에 따른 시대적 이슈에 따라 변천하고 있고 1992년 리우 정상회담 이후 물위기 극복을 위한 새로운 패러다임으로 정착, 물재해 심화에 따라 2000년대 물안보라는 국가 차원의 과제로 발전하였다. 이에 이미 전세계 국가의 68%이상이 도입중이며 모든 국가로 확산 중에 있다. 그러므로 본 연구에서는 향후 통합수자원관리 측면에서의 우즈베키스탄 내 업무와 환경을 분석하여 표준화된 수자원정보화 방향을 제시하고 통합물관리를 위한 통합물관리시스템을 개발하는 것을 목적으로 한다. 우즈베키스탄은 기본적으로 물관리 여건이 매우 불리한 물스트레스 국가로 분류되고 있다. 국가 내에서 필요로하는 대부분의 수자원이 양적으로 매우 부족하고, 강수량의 지역, 시기별 변동폭 역시 매우 크게 나타나고 있다. 또한 이용가능한 수자원을 작물재배가 가능한 시기에 농업용수로 80%이상을 취수하고 있어 심각한 물부족에 시달리고 있는 실정이다. 지정학적으로는 연강수량이 평균 400mm정도로 나타나고 있어 국내에서 생산되는 물 이외에는 국내를 통과하는 시르다리야, 아무다리야 강의 상류에 위치한 키르기즈스탄, 타지키스탄에서 생성된 물을 하천에서 취수하여 사용하고 있는 실정으로 제한된 수자원을 효율적, 합리적으로 이용하는 데 있어 관리기술의 개선이 필요하다. 수자원의 대부분은 수자원부에서 산하 관리조직을 통해 중앙에서 통제하에 관리하고 있으나 국가간, 지역별 용수배분, 갈등이 심하되고 있는 상태에 있으며 이러한 점을 해결하기 위한 상류-하류간 연계, 수량-수질간 연계, 지표수-지하수 연계 등을 위한 법적, 제도적 기반이 미흡한 상태이다. 이러한 우즈베키스탄 내 IWRM 도입의 필요성을 기반으로 통합물관리를 위한 시스템 구성요소를 도출하고 구축을 위해 고려해야 할 사항 및 발전방향을 본 연구를 통하여 제시하고자 한다.

The technical regulation and conformity assessment procedure of our country on ICT equipments is currently required to have more innovation due to the request of main trade countries, the second phase conclusion of MRA, necessity of expansion of conformity assessment service market and demand of manufacturers. The world's leading advanced countries have already proceeded with innovation based on privatization plan. According to the comparative analysis of the level, it turned out that Japan obtained the highest level of privatization while South Korea ranked the lowest level. According to the research result of examination and certification ability of private institutions of our country, it turned out that our country is expected to have possibility of achieving higher level of privatization than that of the present. Moreover, according to the questionnaire survey conducted to the persons concerned regarding privatization direction, they gave positive response to all the indicated survey contents of privatization direction in terms of "delegation of certification services to private sectors (contracting-out)", "transformation of EMC into private voluntary standard" and "changeover of conformity assessment agent". However, from the view of acceptance and conflict model, it is estimated that starting from "delegation of certification services to private sectors (contracting-out)" seems to be the most advisable plan. Also, prior to privatization, it is required to improve relevant systems such as certification examiner system.

Lane detection technology is one of the most important issues on car safety and self-driving capability of autonomous vehicle. This paper introduces an accurate lane detection scheme based on OCC(Optical Camera Communication) for moving vehicles. For lane detection of moving vehicles, the streetlights and the front camera of the vehicle were used for a transmitter and a receiver, respectively. Based on the angle information of multiple streetlights in a captured image, the distance from sidewalk can be calculated using non-linear regression analysis. Simulation results show that the proposed scheme shows robust performance of accurate lane detection.

In this paper, we propose a block-based modularity architecture design method for distributed machine learning. The proposed architecture is a block-type module structure with various machine learning algorithms. It allows free expansion between block-type modules and allows multiple machine learning algorithms to be organically interlocked according to the situation. The architecture enables open data communication using the metadata query protocol. Also, the architecture makes it easy to implement an application service combining various edge computing devices by designing a communication method suitable for surrounding applications. To confirm the interlocking between the proposed block-type modules, we implemented a hardware-based modularity application system.

In the field of information security management systems, one of the representative certifications in Korea is ISMS-P certification, and internationally, ISO/IEC 27001 certification is recognized. When companies acquire both ISMS-P (or ISMS) and ISO/IEC 27001 certifications, budget and manpower are duplicated in similar areas. Therefore, it is necessary for the company to choose and invest in a certification that is suitable for its conditions. This paper proposes a strategy for obtaining information security management system certification that is suitable for the characteristics of the company, allowing for effective information security management based on the company's conditions. To achieve this, data were collected from the Ministry of Science and ICT's Information Security Disclosure System (ISDS), the Korea Internet & Security Agency (KISA), and the Financial Supervisory Service's Data Analysis, Retrieval and Transfer System (DART), and Probit regression analysis was conducted. During the Probit regression analysis, the relationships between seven independent variables and five cases of ISMS-P (or ISMS) acquisition, ISMS-P acquisition, ISMS acquisition, ISO/IEC 27001 acquisition, and both ISMS-P (or ISMS) and ISO/IEC 27001 acquisition were analyzed. The analysis results revealed the relationship between company characteristics, including industry, and certification acquisition in the ISMS field. Through this, strategies for certification acquisition based on company types could be suggested.

Broadcast encryption (BE) is a cryptographic primitive that enables a sender to broadcast a message to a set of receivers in a secure channel. The efficiency of BE is measured by three factors: ciphertext transmission cost, user storage cost, and computational cost for decryption. In general, BE is applied to the environments where a large number of receivers should be accommodated, so that the transmission cost is considered as being the most important factor. In this paper, we suggest a new BE system, using Shamir's secret sharing method, which considerable reduces the transmission cost. In comparison to the previous Subset Difference (SD) system, the transmission size of our BE is longer until $r{\leq}\sqrt{n}$, but get shorter when $r{\geq}\sqrt{n}$ for number of revoked users and n number of total users. We show that the advantage can be achieved at the slight expense of both the storage and computational costs.

In modern society, disasters frequently occur, and the effect is getting more massive. Also, unpredictable future increases anxiety about social security. Accordingly, in order to prevent national-scale emergency from happening, it is highly required governments' role as ICT power nation and transition to disaster management system using big data applied service. Thus, e-gov necessarily acquires disaster response system in order to predict and manage disasters. Disasters are linked with some attributes of modern society in diversity, complexity and unpredictability, so various approach and remedies of them will appease the nation's anxiety upon them. For this reason, this manuscript suggests epidemics preactive warning algorithm model as a mean of reduce national anxiety on disaster using big data for social security. Also, by recognizing the importance of e-gov and analyzing problems in weak disaster management system, it suggests political implication for disaster response.
