윤영민,최종천,유해영,조성제,Yun, Young-Min,Choi, Jong-Cheon,Yoo, Hae-Young,Cho, Seong-Je 한국정보처리학회 2007 정보처리학회논문지 C : 정보통신,정보보안 Vol.14 No.4
In this paper, we propose a method to analyze security vulnerabilities of MS word-processor by checking the validation of its input files. That is, this study is to detect some vulnerabilities in the input file of the word processor by analyzing the header information of its input file. This validation test can not be conducted by the existing software fault injection tools including Holodeck and CANVAS. The proposed method can be also applied to identify the input file vulnerabilities of Hangul and Microsoft Excel which handle a data file with a header as an input. Moreover, our method can provide a means for assessing the fault tolerance and trustworthiness of the target software. 본 논문에서는 MS 워드프로세서의 입력 파일에 대한 유효성을 검사하여 MS 워드프로세서의 보안 취약성을 분석하는 방법을 제안하였다. 즉, 워드프로세서에 적용되는 입력 파일의 헤더 정보를 분석함으로써, 그 입력 파일에 존재하는 취약성을 검출하였다. 본 논문에서 수행한 입력 파일 유효성 테스팅은 기존 결함 주입 도구인 Holodeck 및 CANVAS 등으로는 테스트할 수 없다. 제안한 방법은 헤더를 가진 데이터 파일을 입력으로 사용하는 한글, MS 엑셀 등의 입력 파일에 대한 취약성 검출에도 적용될 수 있다. 또한, 대상 소프트웨어들의 결함 허용성 평가 및 신뢰성 평가에도 사용될 수 있다.

After the 1998 Korea-Japan fisheries agreement, the Korean government was open to the criticism - that the agreement may have given Japan an excuse to assert possession over the Dokdo. The main reason for the criticism regarding the 1998 fisheries agreement is that Dokdo is located in the provisionally arranged zone which is a kind of common management water area stipulated by the agreement. To avoid these criticisms, the Korean government used the Minquiers - Ecrehos case. They asserted that the fisheries agreement and sovereignty of Dokdo are totally unrelated, and they applied the Minquiers - Ecrehos case as a precedent to support their claim. It was because the International Court of Justice excluded the effect of fishery convention between the UK and France to decide the sovereignty of the islands in the Minquiers - Ecrehos case. However, the decision of ICJ in the Minquiers - Ecrehos case should not be applied to Dokdo problem without distinguishing different situations. It is a dangerous attitude to adopt a certain international legal theory to particular cases without considering the specific situations of the disputed area. In the Minquiers - Ecrehos case, the effect of fishery convention to decide the sovereignty of the islands was not the ratio decidendi. The ratio decidendi of the case was the effective possession. Hence, it is unreasonable that the attempt to adopt this case to the 1998 Korea-Japan fisheries agreement. There are many different features between the Minquiers - Ecrehos case and the Dokdo problem such as geographical, historical and political situations. However, the arguments from the Minquiers - Ecrehos case can be applied to the settlement of the territorial dispute over Dokdo. In particular, the Minquiers - Ecrehos case suggests that the evidence of effective possession is the key to solve Dokdo problem.
제임스 케네디(D. James Kennedy)의 전도 신학과 방법에 대한 분석
윤영민 개혁신학회 2008 개혁논총 Vol.9 No.-
The primary purpose of this dissertation is analyzing D. James Kennedy's theology and method of evangelism. Kennedy (1930-2007) and his ministry attempted not only to win souls for God's glory through obeying the Great Commission, but also to reform America's social, cultural, and moral problems through fulfilling the cultural mandate. In particular, he contributed to fulfill the Great Commission through Evangelism Explosion and media ministry. The Evangelism Explosion International ministry (EEI), which he led, became the first Christian ministry to be planted in all the world's 212 nations in 1996. Approximately 100,000 churches in 211 nations have trained their laypeople to witness using the principles and methods of EE ministry. EE's textbook, Evangelism Explosion, has not only been ranslated in more than ninety-five languages, but one-and-a-half million copies have also been distributed in English alone. According to Christianity Today, EE is one of the world's most largely used methods of church-based outreach. Kennedy’s gospel message is essential in his evangelism theology. He delivered the gospel of grace, man, God, Christ, and faith. His gospel message is God’s love message because totally sinful man—who is destined to go to hell due to God’s righteousness—freely receives salvation in grace through faith in Jesus Christ, the Lord and Savior. Such a gospel message is a clear and systematic one. Above all, the emphasis on grace is unique in his gospel message. However, he did not stress repentance. Also, his gospel message is not Calvinistic message, but biblical one although he was a Calvinist. The reason that EE’s gospel message does not emphasize Calvinism is that EE becomes an interdenominational ministry. Kennedy’s EE is significant in his evangelism method. EE is based on New Testament principles of evangelism. EE as lay evangelism not only attempts to fulfill the Great Commission by laypeople, but also adopts on-the-job training. Moreover, EE’s follow-up discipleship overcomes personal evangelism’s limitation because its follow-up program not only obeys making disciples, but spiritually cares for new believers to make mature and trained Christians who can evangelize the lost. EE results in church growth. Thus, EE’s principles are methodogically legitimate. EE’s gospel presentation is a useful and effective personal evangelism method because relational, persuasive, dialogical, and flexible in sharing the gospel presentation. However, the commitment in EE’s gospel outline is problematic in view of Calvinism. Although he was a Calvinist, EE’s commitment could provide easy-believism by the prospect’s intellectual agreement. Its prayer, the so-called Sinner’s Prayer, could be considered as a required gate of conversion; and the evangelist’s declaration after the prayer of commitment could lead the prospect to “easy-believism.” Consequently, the commitment in the gospel presentation should be utilized carefully.
에너지 수출국의 에너지 안보 :러시아와 주요 에너지 수출국의 비교를 중심으로

Energy security research has mainly focused on the supply stability of fossil energy resources for importing countries, considering only the issue of whether energy resources can be supplied reliably and at an appropriate price. Therefore, the concept of energy security for energy producing and exporting countries, such as Russia, seemed non-existent. However, considering the importance of energy production and export for the economy and industry of energy exporting countries, and the dynamics between the demand and supply in the international energy market, the energy security of energy exporting countries can be seen as a real problem, albeit in a different direction than that of energy importing countries. In particular, considering Russia's position in the international energy market and the current situation in the energy market, Russia's energy security can be seen as a factor that can affect not only Russia itself but also the entire international energy market circumstances. Due to the need for such research, this study identified the characteristics of Russia’s energy security compared to major energy exporting countries. Using the energy security index developed in a previous study, this study compares and measures the energy security of Russia, Kazakhstan, Qatar, and Canada. The results shows that Russia's energy security level is relatively high but has structural imbalances and sustainability issues. On the other hand, for more precise measurement and suitable comparison, it is necessary to expand the scope of research to include more countries, and there is a need to improve the energy security index as a tool for inter-country comparison. 에너지 안보 연구는 주로 화석에너지 자원 수입국의 공급안정성을 중심으로 이루어져 왔다. 에너지 안보는 얼마나 안정적으로, 적절한 가격에 에너지 자원을 공급할 수 있는가의 문제로만 여겨졌던 것이다. 따라서 러시아와 같은 에너지 생산 및 수출국의 에너지 안보라는 개념은 존재하지 않는 것처럼 보였다. 하지만 에너지 자원의 생산과 수출이 에너지 수출국가의 경제와 산업에서 갖는 중요성과 국제 에너지 시장의 수요와 공급이 결국은 맞물려있는 문제라는 점을 고려할 때 에너지 수출국의 에너지 안보 역시 에너지 수입국의 그것과는 다른 방향으로 실재하는 문제라 할 수 있다. 특히 에너지 시장에서 러시아의 위치와 현재 국제에너지 시장의 상황을 보았을 때 러시아의 에너지 안보 문제는 비단 러시아만이 아닌 국제 에너지 시장 환경 전체에 영향을 미칠 수 있는 요인이라 할 수 있다. 이러한 연구 필요성에 따라 본 연구는 러시아의 에너지 안보 수준을 주요 에너지 수출국과 비교해 러시아의 에너지 안보가 갖는 특징을 식별했다. 선행연구의 에너지 안보 지수를 활용하여 러시아와 카자흐스탄, 카타르, 캐나다의 에너지 안보 수준을 측정해 비교하였다. 그 결과 러시아의 에너지 안보 수준은 상대적으로 높은 것으로 나타났으나 구조적 불균형과 지속가능성의 문제를 갖고 있는 것으로 나타났다. 한편 보다 정교한 측정과 비교를 위해 연구 대상 국가의 확대가 필요하며 측정 도구인 에너지 안보지수를 국가간 비교에 보다 적합하도록 보완할 필요성을 발견하였다.
러시아의 대 ASEAN 전략 양자관계의 발전과 러시아의 대외정책에서 ASEAN의 위치
윤영민 한국슬라브․유라시아학회 2024 슬라브학보 Vol.39 No.1
Russia and ASEAN are positioned within South Korea's foreign policy as targets of its northern and southern policies. However, domestic research on the relationship between Russia and ASEAN is not extensive. Particularly, studies on Russia's ASEAN policy are scarce. This study aims to fill this scholarly gap by tracing the development of Russia-ASEAN relations and analyzing the value ASEAN holds in Russia's foreign policy. To achieve this, changes in bilateral relations, institutional mechanisms, and economic ties are briefly examined. While ASEAN may not be a top priority in Russia's foreign policy agenda, its importance has been increasingly emphasized in Russia's regional aspirations and post-Ukrainian conflict foreign policy. ASEAN emerges as a significant partner for Russia in balancing relations with China and India, and it holds its own role and value in Russia's Greater Eurasian Partnership and New Eastern Policy. Based on these discussions, the study explores promising areas of cooperation such as energy resources, counterterrorism, and food security, to assess the direction of Russia's ASEAN cooperation policy. However, physical, institutional, and interpersonal connectivity issues hinder cooperation development between Russia and ASEAN. Addressing these obstacles and enhancing exchanges will require additional research and efforts.
Bifidobacterium longum 추출물의 자외선B에 대한 인간 진피섬유아 세포 보호 효능
윤영민,최성진,박우정,이시경,안인숙 한국피부과학연구원 2012 대한피부미용학회지 Vol.10 No.4
Bifidobacterium longum (B. longum ) is a species of gram-positive anaerobic bacterium which can be found intestines of humans. B. longum , a potential probiotic used in the food industry, promotes the health of human intestinal tract by reduction of harmful gram-negative bacteria and toxic molecules. Also, B. longum has numerous biological effects, such as anti-cancer, activation of immune response and reduction of DNA damage. Ultraviolet (UV) irradiation has many adverse effects on skin, including inflammation, alteration in the extracellular matrix, cellular senescence and apoptosis. In this study, we investigated the protective effect of B. longum extracts against UVB-induced cellular damage in human dermal fibroblasts (HDFs). B. longum extracts at concentration 0.01 ~ 0.02% (w/v) did not affect cell viability in HDFs. When UVB-exposed HDFs were treated with B. longum extracts, cell viability was substantially enhanced in a dose-dependent manner. To investigate inhibitory effects against cellular senescence of B. longum extracts in HDFs, we performed SA-β-gal staining. UVB-exposed HDFs with B. longum extracts were decreased SA-β-gal positive cells approximately 40% at the concentration of 0.02% (w/v). Flow cytometry was used to determine changes of cell cycle in B. longum extracts treated-HDFs. UVB irradiation slightly increased the percentage of cell population in the sub-G1phase. However, the proportion of cells in sub-G1 phase were decreased approximately 50% by treatment with B. longum extracts. These results suggest that B. longum extracts reduce UVB-induced cellular senescence and apoptosis in HDFs. Thus, B. longum extracts might be used as a potential agents for protection of UVBinduced skin cell damage.

Direct reduced iron was made using an electric furnace. The reduction ratio of direct reduced iron varied depending on the grade of iron ore. Coal played an important role as a reducing agent in making the direct reduced iron. The coal must contain a suitable amount of volatile components having high calorie values and low impurity content. In this study, oxidized pellets were directly reduced using anthracite as a reductant in an electric furnace. Direct reduction behaviors of hematite and magnetite pellets were confirmed in a coal-based experiment. Reduction behaviors were demonstrated by analyzing the chemical compositions, measuring the reducibility, and observing the phase changes and microstructure. The superior reducibility of hematite pellets can be ascribed to their high effective diffusivity, which is due to their high porosity. The quickly after reducing for 40min and achieves a high value at the end of the reduction.

This study examines the contents and organization of 『文法註釋韓語研究法』 (1909). By doing so, this paper aims to observe the properties of Korean grammar book which was written from the Japanese viewpoint in the end of Korean enlightenment period and to lay the groundwork for reconsidering 『文法註釋韓語研究法』 as a linguistic material. 『文法註釋韓語研究法』 is based on the Japanese grammar conforming to ‘大槻文法’, just as 『韓語通』 and 『韓語文典』 which were published before 『文法註釋韓語研究法』 the same year. 『文法註釋韓語研究法』 classified 10 parts of speech of Korean but it had criteria and nomenclature of its own. Especially, in the part of ‘auxiliary verb (助動詞)’, it classified the Korean auxiliary verbs by their function. This seems to be influenced from 『韓語文典』 at first sight, but its original way of suggesting examples using complete predicates is remarkable and this tendency is also shown in An-Hwak’s 『修正朝鮮文法』 (1923). The research, as a study of theories and their interrelationship in the time of Korean and Japanese grammatical establishment, attempts to recapitulate the Yakushiji’s achievement and analyze 『文法註釋韓語研究法』 by dividing it in four aspects, which are purpose of publishment, setup of organization, content characteristics, and its importance as Korean-Japanese correspondence data. By this process, it figures out both Korean and Japanese transitional aspect throughout the modern enlightenment period, the late Meiji (明治), and present day, as well as how the grammatical categories of Korean are described from the perspective of the Japanese. 본고는 1909년에 간행된 『文法註釋韓語研究法』의 구성과 내용을 고찰함으로써 개화기말 일본인의 관점에서 작성된 한국어 문법서의 특징을 관찰하고 ‘언어자료’로서의 『文法註釋韓語研究法』에 대한 재고의 기반을 마련하여보고자 한 것이다. 『文法註釋韓語研究法』은 같은 해 먼저 간행된 『韓語通』, 『韓語文典』과 같이 ‘大槻文法’에 따른 일본 문법에 기초하였으며 한국어를 10품사 체계로 나누었으나 그 설정과 명명에 나름의 입장을 견지하고 있다. 또한, ‘助動詞’의 기술에서는 한국어 조동사를 기능별 범주로 구분하여 기술하였다. 이는 일견 일본어 조동사에 해당하는 한국어 표현을 대응시킨 『韓語文典』의 영향이 보이는 것이지만 완성된 용언 형태로써 용례를 제시하는 독자적인 방식은 괄목할만하며 이러한 경향은 이후 1923년 안확의 『修正朝鮮文法』을 통해 유사한 양상으로 나타나고 있다. 이번 연구는 한일 양국어의 근현대 문법의 확립과 완성기에 나타나는 이론과 체계적 상호 영향관계의 면면을 살펴보는 기초연구로서 저자인 야쿠시지 지로(薬師寺知曨)의 행적을 개괄하고 간행 목적, 구성 체제, 내용적 특징, 한일어 대응자료로서의 의의라는 네 가지 측면으로 나누어 『文法註釋韓語研究法』의 분석을 시도하였다. 이를 통해 근대계몽기와 明治 말기, 현대 한국어와 일본어로의 변화를 준비하는 시기에 산견되는 양언어의 과도기적 양상을 파악하여보는 한편, 일본인의 시각에서 한국어의 문법 범주와 항목을 어떻게 설명하고 기술하였는지 밝혀보았다.
『皇國文典初學』の「文法」-『日本小文典』と『日本文章法初歩』との比較を中心に-

This study illuminates the concept of ‘Grammar’ defined by Kurokawa Mayori and searches for its types in “Kokoku Bunten Shogaku”. The book was written by Kurokawa Mayori, a kokugaku scholar, and published in 1873. Though he was a kokugaku(styudy of nation) scholar, his book was based on the western-style system such as 3 basic parts of speech(noun, verb, postposition) and additional 6 parts of speech(numeral, pronoun, adjective, adverb, conjunction, exclamation). One of the most interesting features of the book is the fact that he defined ‘Grammar’ as rules of sentences. This definition demonstrates that his idea about ‘Grammar’ is different with current one. We tried to explain his idea according to expressive factors, morphosyntactic categories, and linguistic types. As such, we could understand the perspective on grammatical categories in the 19-century Japan and reveal the value of “Kokoku Bunten Shogaku” on historical grammar of Japanese.
