China has vast land, variety of people, religions and cultures. China has faced terrorism threat from the struggles of people, religions and resources. The 11thStanding Committee of the National People's Congress of China decided to strengthen the anti-terrorism action on October 29, 2011. This study compared, analyzed and estimated the counter-terrorism laws of the USA, Britain and Germany thinking about the China's anti-terrorism decision. The counter-terrorism laws of the USA, Britain and Germany are largely composed of previous prevention of terror and oppression of it later. They enacted the laws both for people and property. They also rearranged the power and role of governmental institutes on counter-terrorism. The contents of the counter-terrorism laws are specific, detailed and systematic. But the anti-terrorism law of China has restriction on the power and roles for previous prevention and oppression of terrorism, handling of people and property. This study reviewed the foreign countries' counter-terrorism laws and the way to connect the regulations on terrorism crimes of the revised Chinese criminal law and the anti-terrorism decision, when they enact the anti-terrorism laws in China in the future.

International society got a severe shock from terrorism of hostage, abduction and murder that was committed on a target of Israel athlete delegation in Munich Olympics, West Germany by Black September, a Palestine terrorism organization. Korea with 1986 Asian Games and 1988 Olympics ahead was directly and indirectly exposed to threats of North Korea's nation-support terrorism, a military provocation and a local war limited warfare. This study explores the roles of the police at the time of the National Police Headquarters with regard to counter-terrorism, and analyzed academic research trends of Studies of Counter-terrorism published by the same office between 1983 and 1990. Looking into them shows a fact firstly, that the most frequently appearing key words in common were "terrorism," "hostages," "measures," and "international," etc. Secondly, before and after 1988 Olympics, the key word "Olympics" was frequently addressed. Thirdly, looking at the difference by the year, the key word, "policies of defense and borderlands" was frequently addressed between 1983 and 1984, "terrorism against South Korea," and "civil aircraft" frequently addressed in 1985, and "corporate" in 1986. In 1987, the key word "terrorism trends" was addressed, and in 1990, "international terrorism," and "separatism" were used.

이대성,양인영,김춘택,양수석,Lee, Dae-Sung,Yang, In-Young,Kim, Chun-Taek,Yang, Soo-Seok 대한기계학회 2003 大韓機械學會論文集B Vol.27 No.12

Monte Carlo simulation(MC) method was used as an uncertainty assessment tool for gas flow measurement in this paper. Uncertainty sources for gas flow measurement were analyzed, and probability distribution characteristics of each source were discussed. Detailed MC methodology was described including the effect of the number of simulation. The uncertainty result was compared with that of the conventional sensitivity coefficient method, and it was revealed that the results were different from each other for this particular gas flow measurement case of which the modelling equation was nonlinear. The MC was comparatively simple, convenient and accurate as an uncertainty assessment method, especially in cases of complex, nonlinear measurement modelling equations. It was noted that the uncertainty assessment method should be selected carefully according to the mathematical characteristics of the measurement.

An Altitude Engine Test Facility(AETF) was built at the Korea Aerospace Research Institute in October 1999 and has been being operated for altitude testing of gas turbine engines of 3,000 Ibf class or less. The AETF has been calibrated using several engines such as J69 of Teledyne Co. as a facility checkout engine. Uncertainty analyses on the air flow rate and thrust were performed using the test results, according to ASME PTC 19.1-1998. Several modifications on the facility and test method were made in order to improve the measurement uncertainty to a satisfactory level over the whole operating envelop. Spatial distributions of pressure and temperature were measured, sensors were substituted by more accurate ones, inlet duct was modified to refine the flow quality, and pressure control logic was revised to remove the cell pressure fluctuation. As a result, the uncertainty of the air flow measurement was improved by 0.1% over all the test conditions, and the net thrust measurement by up to 3%. The improved measurement uncertainties of air flow and thrust are 0.68~O.73% and 0.4~1.3%, respectively.

중재 쓰레드와 지연 캐싱에 의한 스퀴드 프록시 서버 성능 향상에 관한 연구

이대성,김유성,김기창,Lee, Dae-Sung,Kim, Yoo-Sung,Kim, Ki-Chang 한국정보처리학회 2003 정보처리학회논문지 C : 정보통신,정보보안 Vol.10 No.1

인터넷 사용자의 폭발적인 증가로 인해 캐시 서버의 사용이 대두되고 있다. 이에 따라 캐시 서버의 성능을 향상시키기 위한 많은 연구들이 진행되었다. 본 논문에서는 캐시 서버의 병목 현상을 유발하는 원인을 분석하고 그에 대한 해결책으로 중재 쓰레드와 지연 캐싱을 제안한다. 중재 쓰레드를 사용함으로써 캐시 서버가 디스크 쓰기 연산 시에 준비된 다중 쓰레드를 탐색해야 하는 문제점을 없애고 즉시 사용자의 서비스 요청에 응답함으로써 보다 빠른 서비스를 제공할 수 있도록 한다. 또한 준비된 다중 쓰레드가 없는 경우에는 지연 캐싱을 이용해 과부하 상태의 디스크 연산을 피하고 큐가 안정화될 때 캐싱을 하도록 하여 시스템이 안정성 있게 동작하도록 하였다. 제안된 캐시 서버는 스퀴드(SQUID) 캐시 서버를 변형하여 구현되었고 실험을 통해 기존 스퀴드 캐시 서버의 성능과 비교한 결과, 응답 시간의 향상을 관찰할 수 있었다. As the number of the Internet users increases explosively, a solution for this problem is web caching. So, many techniques on improving cache server performance have been suggested. In this paper, we analyze the cause of the bottleneck in cache servers, and propose an arbitral thread and delayed caching mechanism as a solution. We use an arbitral thread in order to provide a quick service to user requests through eliminating the ready multi-thread search problem in case of disk writing operation. We also use delayed caching in order to provide stable system operation through avoiding overloaded disk operation and queue threshold. Proposed cache server is implemented through modification on SQUlD cache server, and we compare its performance with the original SQUID cache server.

The proposed system architecture, design work in the field and in the utilization of one model are expected to be.

북한의 대남테러리즘 분석과 향후전망

이대성(Lee, Dae Sung) 한국테러학회 2012 한국테러학회보 Vol.5 No.1

김일성은 1958년 무력으로 최고인민회의를 점령한 후, 김두봉 등과 같은 외세 의존세력을 모두 숙청함으로써 1인 독재체제의 기틀을 마련하였고, 마르크스·레닌주의를 계승한 주체사상으로 1인 독재체제의 사상적 기반을 강화하였으며, 이를 통하여 영도적 수령체제를 구축하였다. 김정일은 김일성의 장남으로 1961년 7월 조선노동당에 입당한 후, 1970년대부터 경쟁관계에 있던 숙부 김영주를 실각시키고, 이복동생 김평일을 제거하였다. 김정일은 1980년 제6차 당(黨)대회를 통하여 김일성의 공식적인 후계자가 되었고, 1991년 12월 조선인민군 최고사령관직에 취임함으로써 2대 권력세습체제를 공고히 하였다. 1994년 김일성 사망 이후, 유훈통치 기간을 통하여 실질적 권력을 장악하여 제1통치자가 되었다. 김정일은 2010년 10월 10일 노동당 창건 제65주년 기념일에 김일성·김정일의 세습체제를 계승할 후계자 김정은을 화려하게 등장시킨 후, 2012년 12월17일 갑자기 사망하였다. 현재 북한은 국제사회에서 유래(由來)를 찾아 볼 수 없는 김일성·김정일·김정은 3대 봉건세습체제를 계승하려는 특수한 집단으로 전락하였다. 이러한 북한은 남북 분단 이후부터 최근까지, 한국을 대상으로 국가지원테러리즘을 지속적으로 자행하였기 때문에 향후 북한의 대남 테러리즘에 관심을 가져야 할 것이다. 이 연구에서는 북한 테러리즘을 이론적으로 검토하고, 김일성과 김정일 집권기에 한국을 대상으로 자행한 테러리즘을 구분하여 분석함으로써, 김정은 집권기에 발생 가능한 대남 테러리즘을 전망하고자 한다. Kim Il-sung had been the absolute power in North Korea from September 1948 to his death, which happened on July 8, 1994. Kim Il-sung brought about Korean War based on his misconception that many people would support for North Korea because of despotism of Lee Seung-man in South Korea and military supplies and armors he secured from Russian's military supports. Although he was one of those who should be responsible for Korean War, he blamed Park Heon-young of Namrodang, Mujeon of Yeonanpa and Heo Ga-i of Soryeonpa. He dominated Supreme People's Assembly by force in 1958 and purged all foreign country dependent groups including Kim Du-bong to secure his single dictatorship. He enforced the ideology of the single dictatorship based on 'Juche' Idea succeeding to Marxism and Leninism, and constructed so called 'Leading Suryeong' system. Kim Jong-il is the first son of Kim Il-sung. He entered Chosun Nodongdang(labor party in North Korea) in July, 1961, defeated his uncle Kim Young-ju and removed his half-brother Kim Pyung-il in the power game. He became the official successor of Kim Il-sung at the 6th Annual Conference of Nodongdang and secured the 'Two Generation Power Transfer' by taking the office of the Supreme Commander of North Korean People's Army in December. He seized the actual power through 'Precepts Ruling' period after the death of Kim Il-sung in 1994 and became the supreme ruler. He introduced his successor Kim Jong-un who would rule North Korea succeeding Kim Il-sung and Kim Jong-il himself on the 65th anniversary of Nodongdang on October 10, 2010, and died suddenly on December 17, 2012. Currently, North Korea is despised as an peculiar group to practice three generation power transfer such as Kim Il-sung, Kim Jong-il and Kim Jong-un, which could not be found in any other country. As the very North Korea has been executing terrorism against South Korea with the support of their government, terrorism of North Korea against South Korea should be reviewed and studied. In this study, it was tried to prospect the terrorism against South Korea which could occur during Kim Jong-un era by reviewing North Korean terrorism theoretically and analyzing terrorisms by classifying them as Kim Il-sung era and Kim Jong-il era.

현행 「국가대테러활동지침」에 대한 비판적 검토

이대성(Lee, Dae Sung),김상원(Kim, Sang Weon) 한국테러학회 2014 한국테러학회보 Vol.7 No.1

국제스포츠행사는 인류 번영과 평화를 기원하는 화합의 장(場)으로써 그 의미가 크다고 할 수 있다. 그러나 이러한 국제스포츠행사의 의미가 국제테러리즘에 의해 퇴색되는 경우가 자주 발생하고 있다. 그 대표적인 사례로는 1972년 제10회 뮌헨올림픽대회에서 팔레스타인 테러조직 검은9월단(Black September)에 의해 이스라엘 선수단이 피살된 사건이 있다. 한국도 1988년 서울올림픽대회 개최를 앞두고 국제테러리즘과 북한 국가지원 테러리즘에 대응하기 위하여 1982년 1월 22일 대통령훈령 제47호 「국가대테러활동지침」을 제정ㆍ시행하였다. 그러나 행정규칙인 동 지침으로 국가와 국민의 안전과 직결되는 대(對)테러리즘 행정을 규율하는 것은 법치주의 요구에 배치된다. 또한 동 지침은 그 내용이 불명확하여 유추ㆍ확대 해석할 가능성이 있고, 테러리즘 발생에 대한 예측가능성과 법적안정성이 미흡하다. 그리고 대통령훈령 제47호 「국가대테러활동지침」은 '테러리즘' 정의에 대량살상무기(WMD)를 이용한 생화학테러리즘(Biochemical Terrorism)을 명시적으로 규정하지 않고 있어 법(法)논리의 일관성에 한계가 있고, 또한 국무총리가 테러대책회의 의장이 됨으로써 대(對)테러 관련 군병력(軍兵力)과 장비(裝備)를 테러리즘 발생지역으로 신속하고 체계적으로 이동시키지 못하는 문제도 있다. 이에 이 연구에서는 행정규칙인 대통령훈령 제47호의 한계를 극복하기 위하여 (가칭) 「테러방지법」의 제정을 제안하고자 한다. 만약 (가칭) 「테러방지법」의 제정에 어려움이 있다면, 동 지침의 내용에 생화학테러리즘에 대한 부분을 명기(明記)하고, 테러대책회의 의장을 국군통수권자인 대통령으로 변경하며, 대테러 활동을 3단계에서 4단계로 세분화하는 등의 개선책을 모색하는 것이 바람직하다고 본다. International sports events have a special meaning to pray for the prosperity and peace of humankinds. However, these days these international sports events get interrupted frequently by international terrorism. Famous example is the incident that Israeli players were killed by Black September in the 10th Olympic Games in Munich in 1972. On the occasion of Seoul Olympics in 1988, Korea enacted and enforced 「Guidelines for National Counter-terrorism Activities」to respond against international terrorism and government supported terrorism by North Korea on January 22 in 1982 as Presidential Directive No. 47. However these administrative guidelines do not meet expectations as they are counter-terrorism administration based on legalism principle and do provide predictability and legal stability. Additionally, as Presidential Directive No. 47 「Guidelines for National Counter-terrorism Activities」don't explicitly refer to the biochemical terrorism using weapon of mass destruction, there are limitations in consistency of legal logic. Furthermore, as Prime Minister chairs Counter Terrorism Committee, it is difficult to move military force and equipment to terrorism event occurring place fast and systematically. To resolve such difficulties and overcome limitations of Presidential Directive No. 47 「Guidelines for National Counter-terrorism Activities」as an administrative regulation, it is proposed to enact so called 「Anti-Terrorism Act (tentative name) 」. If there are difficulties in enacting 「Anti-Terrorism Act」we may add biochemical terrorism to these existing guidelines, change the chair of Counter Terrorism Committee to President who is the supreme commander of the armed forces, and improve counter-terrorism activities from the three steps to 4 steps by breaking down the stages.

The purpose of this study is to investigate how CEOs and managers of the professional sport clubs should communicate with the media when a serious crisis situation occurs. For this purpose, the research question was developed to identify effective crisis communication strategies when a match fixing event occurs in professional sport clubs. The Python programming language, the latest big data analytics tools for unstructured data analysis, web scraping, and machine learning algorithms were used to analyze the news articles. In this study, a crisis communication strategy was derived by analyzing 1,365 sentences in 321 articles of four baseball clubs related to the umpire money transaction scandal. In detail, the sentences classified into 8 categories by each clubs were grouped by time zone, and they were visualized by graph mapping. Next, the effectiveness of the strategic choice pattern was analyzed, using the number of news articles and on-line replies as a measure. As a result of the study showed that the Doosan Bears followed various strategies over all stages. Nexen and Kia took ad hoc response. Samsung consistently conducted systematic strategic responses. It can also be found that Samsung and Nexen made effective responses, while Doosan's and KIA's responses were relatively ineffective. This study indicates that the crisis stages and the communication strategies influence effective crisis communication in professional sport clubs. It was found that an effective pattern was responded with denial strategy at the break out stage. And denial and corrective action was effective response strategies at the crisis event stage. It was also found that a short response with full apology and corrective action was good strategies at the post crisis stage. This study also presents differentiated crisis communication guidelines that can be applied to actual crisis management situations. 본 연구는 2017년 프로야구단 심판금전거래 사건에 대한 사례분석을 통해 위기상황시 효과적 위기커뮤니케이션 전략에 관한 가치있는 시사점을 모색하고자 했다. 이를 위해 파이썬(python) 프로그래밍 언어를 활용한 자동화된(automated) 방법과 수동화(manual) 방법을 병행해, 해당사건에서 4개 구단이 언론에 입장을 밝힌 부분을 발췌해 데이터로 수집했다. 전처리(preprocessing) 작업 후 파이썬(python) 코딩을 통해 주제어 빈도분석(keyword frequency analysis)을 실시했다. 다음으로, 해당사례의 관련기사 321건에 나타난 총 1,365개 문장에 대한 위기커뮤니케이션 전략 분석을 실시했다. 먼저 4개 구단의 입장을 개별 문장으로 분리해 8개의 위기커뮤니케이션 전략 카테고리로 구분했고, 이를 시간대별로 구분해, X축과 Y축 2사분면에 그래프로 mapping해 구단들의 위기커뮤니케이션 전략패턴을 추출했다. 다음 단계로 해당 전략패턴에서의 댓글수와 기사수 측정을 통해 효과성을 분석했다. 연구결과 해당사례에 대한 4개 구단의 입장부분에서, 가장 많이 기사에 등장한 단어는 ‘팬’으로 총 367회 등장했던 것으로 나타났고, ‘심판’(346회), ‘구단’(308회), ‘사실’(260회), ‘여러분’(240회), ‘빌리다’(238회) 등으로 확인됐다. 두산은 전 단계에 걸쳐 다양한 위기커뮤니케이션 전략을, 넥센과 KIA는 체계적이지 않은 임기응변식 대응을, 삼성은 체계적인 전략적 대응을 일관되게 진행했던 것으로 유추할 수 있었다. 또한 삼성과 넥센은 효과적인 대응을, 두산과 KIA는 상대적으로 효과적이지 못한 대응을 한 것으로 추론할 수 있었다. 해당사례에서 승부조작(심판 금전거래) 관련 사실이 공개되기 전인 위기발생(break out)단계에서는 부정하기(denial)를 비롯한 방어적(defensive) 전략으로 대응하고, 위기상황(crisis event)단계에서는 언론대응을 최소화하며, 바로 사후(post crisis)단계로 전환할 수 있도록 빠른 시간에 사과하기(full apology) 및 시정조치(corrective action)와 같은 수용적(accommodative) 전략을 사용하는 패턴이 효과적 대응이었던 것으로 나타났다.

강원,경북지역 낙엽송 지위지수 적합성 평가에 관한 연구

이대성 ( Dae Sung Lee ),이의섭 ( Eui Sub Lee ),최종현 ( Jong Hyun Choi ),서영완 ( Yeong Wan Seo ),최정기 ( Jung Kee Choi1 ) 한국임학회 2014 산림과학 공동학술대회 논문집 Vol.2014 No.-

본 연구는 강원 및 경북지역의 낙엽송 지위지수의 적합도를 평가하기 위해 실시되었다. 연구자료는 강원 및 경북지역의 45개 낙엽송 인공림 표준지 조사로부터 우세목 1본을 선발하여 수간석 해를 통해 분석되었다. 산림청에서 개발된 지위지수표에 의거하여 본 연구대상지의 지위지수를 산정한 결과, 지위지수가 18 이하로 낮은 지역은 8곳(18%)이었으며, 지위지수가 20 이상으로 우수한 지역이 37곳(82%)으로서 대부분 지역에서 지위지수가 우세하였다. 지위지수곡선의 적합도를 평가하기위해 수간석해목의 과거에서 현재까지의 수고생장에 따른 지위지수의 변화를 도시한 결과, 초기 임령 때 지위지수와 차이가 없는 곳은 단지 8지역(18%)이었으며, 지위지수가 2∼4 m 차이가 발생한 지역이 19곳(42%), 6 m 이상 발생한 지역이 18곳(40%)으로 나타났다. This study was performed to evaluate the compatibility of site index for Larix kaempferi in Gangwon and Kyeongbuk regions. The data were collected and analyzed from stem alalysis of one dominant tree at each of 45 permanent plots installed in the regions. The result of site index estimation following the site index table developed by Korean Forest Service (KFS) showed that 8 plots (18%) were less than site index 18 and 37 plot (82%) greater than site index 20. Height growth changes of stemmed trees until present were illustrated in a graphic form to evaluate the compatibility of site index curve. The result showed that only 8 plots (18%) did not show any change of site index as trees age, 19 plots (42%) fluctuated in 2∼4m and 18 plots (40%) over 6m.
