With the development of IT technology, various services such as artificial intelligence and autonomous vehicles are being introduced, and many changes are taking place in our lives. However, if secure security is not provided, it will cause many risks, so the information security becomes more important. In this paper, we analyzed the research trends of main themes of information security over time. In order to conduct the research, 'Information Security' was searched in the Web of Science database. Using the abstracts of theses published from 1991 to 2016, we derived main research topics through topic modeling and time series regression analysis. The topic modeling results showed that the research topics were Information technology, system access, attack, threat, risk management, network type, security management, security awareness, certification level, information protection organization, security policy, access control, personal information, security investment, computing environment, investment cost, system structure, authentication method, user behavior, encryption. The time series regression results indicated that all the topics were hot topics.

김태경,Kim, Taekyung 한국벤처창업학회 2014 벤처창업연구 Vol.9 No.6

창업은 일자리 창출과 신성장 동력 발굴의 적극적인 대안으로 인식되어 왔으며 창업투자회사는 이러한 활동에 주요한 역할을 담당할 것으로 기대된다. 그럼에도 불구하고 창업투자회사의 활동과 창업 활동 간의 상관관계에 대한 학계의 실증적 분석은 부족한 실태다. 1998년부터 2014년까지의 시계열 데이터를 분석한 결과 본 연구는 창업투자회사가 벤처 기업 창업을 양적으로 견인한 인과성이 있음을 밝혔다. 또한 벤처 기업의 창업이 청년 실업 문제를 단기간에 해소하기에는 부족하다는 것과 산업별 벤처 기업과 청년 실업 간의 관계가 다르다는 점도 발견했다. 본 연구는 창업투자활동과 벤처 창업 간의 상관성을 시계열적으로 고려하고 인과분석 시도함으로써 창업투자회사 육성에 관련된 연구와 전략 개발 그리고 정책 수립에 시사점을 준다. The creation of new venture firm has been regarded as a key of creating more job opportunities and discovering new value engines for various industries. It is positively expected that venture capitals play an important role of supporting the process. Nevertheless, there is a scant of research efforts to analyze empirical data for understanding cross-correlations between investment of venture capital and new venture foundation. To fill the gap, this study investigated sets of time-series data from 1998 to 2014 in the context of South Korean economy. The results reveal that venture capitals have contributed significantly to the quantitative increase of venture firms. In addition, the findings show that the creation of new venture fails to yield a direct impact on resolving young unemployment problems in short term. The paper contributes to the research community on new venture foundation by providing insightful views.

In the area of hotel and tourism sector, various research are analyzed using big data. Big data is being generated by any digital devices around us all the times. All the digital process and social media exchange produces the big data. In this paper, we analyzed the de-identification method of big data to use the personal information of hotel guests. Through the analysis of these big data, hotel can provide differentiated and diverse services to hotel guests and can improve the service and support the marketing of hotels. If the hotel wants to use the information of the guest, the private data should be de-identified. There are several de-identification methods of personal information such as pseudonymisation, aggregation, data reduction, data suppression and data masking. Using the comparison of these methods, the pseudonymisation is discriminated to the suitable methods for the analysis of information for the hotel guest. Also, among the pseudonymisation methods, the t-closeness was analyzed to the secure and efficient method for the de-identification of personal information in hotel.

Owing to the change of economic trends, the importance of the tourism industry is growing more and more. In particular, the number of foreign tourists continues to increase and the type of tourists is being changed into FIT (Foreign Independent Traveler). Therefore it is an important issue to provide the effective information to foreign tourists. To solve these problems, a variety of IT technology is being used in the tourism information systems. Especially the location based tour information service is being emerged. This kinds of tourism information service is a type of LBS (Location Based Services). But if the security of the location based tourism information service is not guaranteed, it can lead to many dangers. In this paper, the trends of location based tourism information service are surveyed. Also the security threats and countermeasures for the location based tourism information service are analyzed. This paper suggests secret considerations for the location based tourism information service.

The digital forensic analysis ensures the integrity of confiscated data by calculating hash values for seizure and search of digital evidence and receiving confirmation and signature from participants. However, evidence that is irrelevant to the alleged offense needs to be deleted even after seizure from the point of view of privacy. But the hash value is altered by deleting the irrelevant data from the image file, one will not be able to prove that the file is in the initial state when it was seized. Therefore, in this paper, a study was conducted to support the integrity of the digital evidence, even if some of the seized digital evidence was deleted or damaged during the seizure search. The hash value of each data is calculated and hash value of the combination of hash values are also calculated. Even if the unrelated evidence is deleted from the seized evidence regardless of file system such as FAT or NTFS, the suggested method presented a way to provide the integrity that proves there is no change in the evidence file.

As new Information technology such as IoT develops rapidly, a lot of changes are occurred in our lives. The Internet of Things is the network of physical objects or things embedded with electronics, software, sensors and connectivity to enable it to achieve greater value and service by exchanging data with the manufacturer, operator and/or other connected devices. This change is also applied to tourism industry. These days many people make a tour reservation using the internet. But it is required to consider the efficiency and security of tour reservation system. In this paper, we suggest a tour reservation system. First, we describe the computer reservation system, hotel reservation system and reservation system. Second, we perform the modeling of general reservation system and suggested reservation system. Third, performance evaluation is carried out with respect to efficiency and security. The results show that the suggested reservation system has a better performance than a general reservation system. At last we described the results and future works.

‘당의 붉은 작가’의 탄생 -1950-1960년대 북한 문예 인텔리 세대교체와 ‘문학에서의 당의 유일사상체계’의 형성-

김태경 ( Kim Taekyung ) 국제한국문학문화학회 2021 사이 Vol.30 No.-

본 연구는 소위 ‘주체노선’으로 알려진 북한의 ‘당의 유일사상체계’가 선언된 1967년 이후 확립된 ‘문학에서의 당의 유일사상체계’의 중요한 조직적 조건으로서 ‘당의 붉은 작가’의 형성과정을 밝힌다. 본 연구의 차별성은 1930년대 소련의 사회주의 리얼리즘 ‘원형’의 토착화 관점에서 논리 및 조직적 체계 양 측면을 함께 살펴봄으로써 ‘당의 유일사상체계’ 확립에 이르는 북한 사회주의 문예 형성의 과정에서 문예 인텔리, 행위자들의 역할 및 그 사회적 지반을 조명하는 데 있다. 소련 사회주의 리얼리즘 원형의 이론적 수용과 함께 체제형성기 ‘공화국’에서 교육을 받고 자라난 새로운 세대라는 인적 조건, 새로운 ‘사회주의 건설’의 물적 토대를 바탕으로 한 새로운 기층 인민대중 출신 인텔리들의 부상 및 세대교체의 동학으로 ‘문학에서의 당의 유일사상체계’ 형성을 설명함으로써 본 연구는 문예 부문 내부 논리에 국한되지 않는, 사회적 변동과 긴밀히 연계된 문예 부문에서의 ‘사회주의 건설’ 과정을 보이는 데 의의가 있다. This paper explores the formation process of the ‘red writers of the Party,’ which consisted of an essential organizational condition for the ‘Monolithic Ideological System of the Party in literature’ established by 1967. North Korea’s establishment of the ‘Monolithic Ideological System of the Party’ was a project of making the party-state that encompasses both economy and culture under revolutionary change. Being a part of the whole process, the making of the socialist literature and arts was a vital component that could also promote and influence the holistic change. This paper first analyzes the reception of the principle of ‘class-mindedness’(klassovost’) among the basic categories of socialist realism, which offers the model for the indigenized version of socialist realism, or the making of socialist literature and arts on their own in North Korea. More importantly, along with the theoretical category’s reception, this paper probes how the new generation of revolutionary intellectuals made their way into society in line with changes in education policy. The rise of the group of new writers was situated in the context of changing education and intellectual policies at the time, which opened a space for the newly educated workers and peasants with the minimum level of middle school education. In addition to the new generation of writers, traditional elites who have proven their loyalty to the party-state could be incorporated into red writers of the Party. By highlighting the social base of the red writers of the Party, this paper contributes to a better understanding of the making of socialist realism in North Korea in terms of both ideological and organizational formation.

1950년대 북한의 ‘평화공존의 마음들’ ―소련 ‘평화공존’ 노선의 수용과 북한의 군비축소 담론―

김태경 ( Taekyung Kim ) 한림과학원 2020 개념과 소통 Vol.0 No.26

본 연구는 냉전 초기 북한의 ‘평화정책’을 소련을 중심으로 한 국제 사회주의 진영이 공유한 ‘평화공존’ 노선의 북한적 수용으로 파악한다. 본 연구는 북한의 평화정책, 즉 당대 소련의 평화공존 노선의 북한적 수용이 크게 1) 평화유지, 2) 평화통일, 3) 평화건설이라는 상호연결된 세 가지 축으로 구성된다고 보고, 세 축 중 필수조건으로서 선차성을 갖는 ‘평화유지’에 초점을 맞춰 이를 당대 소련의 ‘평화공존’ 중 군비축소 담론의 수용으로서 탐색한다. 본 연구는 구체적으로 소련 ‘평화공존’ 노선에 따른 재래식 전력의 전반적 병력축소 및 국제적 통제, 그리고 비핵무기지대 제안을 포함하는 원자 및 수소무기 금지 담론과 연동된, 북한의 조선인민군 병력축소 사업 및 중국인민지원군의 철거, 극동 및 아세아에서의 비핵무기 평화지대 담론을 검토한다. 소련 평화공존 노선의 역사적 맥락에서 북한 ‘평화정책’의 일단으로서 군비축소 노력을 검토함으로써, 본 연구는 정전 이후 북한의 평화공존 개념을 보다 풍부화하고 역사적으로 존재했던 한반도 ‘평화공존의 마음들’의 복합적 지형을 드러내는 데 기여할 것이다. 또한 한반도 내 ‘평화공존’ 개념과 관련해 존재했던 다양성의 복원을 통해 현재 한반도 평화 프로세스를 위한 담론적 자원을 제공할 것이다. North Korea’s concept of peaceful coexistence, in the context of the Soviet understanding of peaceful coexistence during the early Cold War, consists of three principal poles: first, disarmament; second, the institutionalization of peaceful coexistence via confederation/federation; and third, the peaceful development of a (socialist) economy. Each theme constructs diverse discourses and practices for the North Korean peace policy of the 1950s: 1) peacekeeping, 2) peaceful unification, and 3) peaceful construction (of the economy). This article focuses on the theme of disarmament, one of the components of this tri-partite peace policy. The North Korean translation of the contemporary Soviet conception of peaceful coexistence is analyzed, particularly as it concerns disarmament, based upon official statements and decisions, and supplemented by magazine articles and literary representations. North Korea's “peacekeeping” policy of the 1950s, as evidenced by its disarmament efforts in line with Soviet disarmament initiatives, contributes to our better understanding of the early Cold War alternatives for peacemaking, and this can shed some useful light upon the current peace process on the Korean Peninsula.
