This study analyzes previous researches from 1990 to 2020 to assess achievements and limitations and provide a direction for future research due to research on North Korean cities research is valuable for understanding North Korea. Achievements include: firstly, contributing to a three-dimensional understanding of North Korea by identifying urban space structures that are changing according to the markets, power relations in cities, social relations networks, and the lives of residents; secondly, strengthening the academic identity of North Korean Studies by using concepts of urban history, urban politics, etc, and utilizing various research methods such as deep interview surveys, GIS and SNS; thirdly, understanding in detail, through the use of central power-oriented studies, how central power is projected in cities that were marginalized in the past. However, limitations were also revealed. Firstly, in order to improve understanding of North Korean cities, knowledge of the North Korean system and other academic knowledge must be combined synergistically, but North Korean Studies has often not been combined with general academic knowledge in this way. Secondly, it is desirable to study North Korean cities consistently and continuously, but the research was somewhat sporadic in nature due to a lack of assistance by government authorities. Thirdly, in terms of content, it is difficult to find comparative research studies between North Korean cities or with cities in countries that have undergone system change. In addition, only 11 out of 28 North Korean cities have been studied. This can be attributed to the accessibility of the research data and the path-dependence of the research, but it undermines the research objectives and precludes a comprehensive understanding of North Korean cities. This study draws several conclusions based on the results of the analysis. Firstly, recognizing that changes in North Korea have various aspects and causes, studies regarding cities and residents should be done more consistently. Secondly, it would be desirable to see more collaborative research with public institutions such as the National Research Institute and LH, which have collated the results of research on North Korean cities, as well as joint research between North Korean Studies majors and other departmental majors. Thirdly, in terms of research methodology, Western urban theory should not be used exclusively, but an analytical system should be developed that reflects the unique context of Korea as a divided country. Finally, research on cities that have not yet been studied is desirable, such as inland urban areas, in order to properly examine North Korea, as is comparative research not only between North Korean cities but also with other cities in a changed-system context

남북통합 과도기 권력구조에 대한 협의주의(Consociationalism) 적용방안 탐색

박성열(Park, Sung-Yul) 숭실대학교 사회과학연구소 2017 사회과학논총 Vol.19 No.-

본 연구는 권력공유 이론 중 분열과 갈등이 심한 지역의 정치적 안정 확보에 효과적인 협의주의(consociationalism)를 남북 통합과정에 적용해보고 교훈점을 찾기 위해 진행되었다. 협의주의는 ‘정부는 단순히 다수의 이익을 대변하는 것이 아니라, 가능한 많은 사람들의 이익을 보호할 때 정치적, 사회적 안정을 담보할 수 있다’라는 믿음에서 시작하며, ① 소수세력 포함 대연정 ② 분절적 자율성 ③ 공직진출의 비례성 ④ 특정그룹의 결정적 이해관계와 관련한 거부권이 전제되는 제도적 장치이다. 한편 남북한은 통합과정에서, 각각 국가연합과 낮은 단계의 연방제를 제안하고 있어 공통의 요소를 감안한 권력구조는 남북 정상회의, 남북 동수의 각료회의 및 평의회를 상정하고 있다. 현재 고려할 수 있는 남북통합 과도기 권력구조에 협의주의 조건을 적용해본 결과, 남북정부의 자율성과 남북동수의 통합기구 구성 및 남북지역 간 상호 단절, 국제적 연계성, 규모의 상대적 균형 등 긍정 요인과 남북 간 사회경제적 격차, 온건 중도그룹 부재․협상전통 미흡 등 부정 요인이 혼재한 것으로 평가되었다. 협의주의의 이론적 엄밀성이 미흡하고, 남북통합 권력체계도 정립되지 않아 실제 적용에 한계가 있다. 그럼에도 남북통합과정의 정치적 안정 확보를 위해 과도기 권력구조에 시론적으로 협의주의 적용 여건을 탐색해 봤다는데 의의를 두고자 한다. The purpose of this study is to adopt Consociatinalism at the process of South and North Korea"s Integration for securing political stability. Consociationalism known as an effective way to guarantee political stability assumes 4 institutional factors: grand coalition including minorities, segmental autonomy, proportional representation on the public official, special group"s veto power. Two Korea suggest each other"s Unification formula: Confederation and low level of Federal state. The common factors of the transitional power structure reflecting South and North"s formula in the process of integration are summit conference, cabinet meeting consisting of same member between South and North, and council. Adopting Consociationalism to these power structure, both positive and negative factors are found. 5 positive factors; Both Korea government"s autonomy, Integrative instituion consisted of same number, Segregation between South and North, International relation, Balance at size between South and North. Also negative factors are social economical gap between South and North, absence of the moderate political groups, lack of negotiation tradition. Adopting and confirming the possibility of the Consociationalism to South and North Korea"s integration process is the useful outcome.

박문성(Park Moon Sung),오주병(Oh Ju Byoung),진병운(Jin Byeong Woon),김혜규(Kim Hye Kyu),박성열(Park Sung Yul) 한국정보처리학회 1995 정보처리학회논문지 Vol.2 No.5

차세대 지능망(AIN : Advanced Intelligent Network)과 X.500 디렉토리 서비스 사이의 관계에서 AIN의 SCF/SDF(Service Control Function/Service Data Function) 인터페이스 요구 사항과 X.500 능력(Capabilities) 간에는 많은 유사성이 존재한다. 또한 X.500의 DUA(Directory User Agent)는 SCF, DSA(Directory System Agent)는 SDF로 매핑 관계과 성립된다. 이러한 유사성과 매핑 관계를 기반으로 AIN에 X.500 디렉토리 시스템을 SCF/SDF 관계에 DAP(Directory Access Protocol), SDF-SDF 관계에 DSP(Directory System Protocol)를 적용할 수 있다. 본 논문에서는 CS(Capability Set)-1, CS-2, CS-3 범위에서 X.500 DAP/DSP 적용이 가능한 관계를 보이고, AIN의 분산 처리를 위한 AIN SDF Server를 설계했으며, UPT(Universal Personal Telecommunication) 서비스를 AIN SDF Server에 적용할 수 있도록 X.500 스키마를 제안하였다. Advanced Intelligent Network(AIN) and X.500 directory service have similarity in between X.500 capabilities and requirements for the Service Control Function(SCF) to Service Data Function(SDF) in AIN. As an interface, SCF can be mapping as a Directory User Agent(DUA) and SDF can be mapping as a Directory System Agent(DSA). Based on the concepts, X.500 directory can be applied to AIN. In this paper we suggest to apply the X.500 DSP to the SDF/SDF interface to perform a distribution function. Also we show that the SCF-SDF/SDF-SDF relationship can be possible under applying X.500 DAP/DSP within the set of Capability Set 1(CS1), CS2 and CS3. Finally, based on the above contents, we introduce the designed schematic of AIN SDF Server System of a distributed processing in AIN and design the X.500 schema of Universal Personal Telecommunication(UPT) service for supporting AIN SDF Server.

WWW has taken root in Internet as a means of future shopping. But, payment systems using todays show us several security vulnerabilities. The problem that plain shopper's credit card details are transferred in Internet is included. These risks can break out not only an infringement of private information but also economic crime. To solve these risks, we introduce the technique which implement the encrypted WWW communication using PGP. And we propose SCCP which is new electronic payment protocol. As a result of testing with criteria from IBM, we can find that SCCP is safe and secure electronic payment protocol.

As considerable investment should be made for additional facilities, it is an important matter for a Server to find optimal size of the Queuing Systems. A simulation model, utilizing stochastic process, is developed in this thesis to solve the problem. Additative congruential method, producing pseudo-random number is used to make out the number of customer arrivals and to measure the service hours. A Frequency Test Serial Test, Gap Test and Poker Test are performed to test the randomness of the random numbers. For the purpose of producing the data to determine an optimal system customer's arrival time and service hour are calculated by combining average arrival rate and average service rate with the generated random numbers and to determine system status, average waiting tine, average queuing length and server's idle time, etc., a general purpose queuing simulation model was developed.
