동해 울릉분지 남부의 플라이오-제4기 탄성파 층서 및 퇴적역사

조민희,유동근,Joh, Min-Hui,Yoo, Dong-Geun 한국해양학회 2009 바다 Vol.14 No.2

동해 울릉분지 남부에서 취득한 다중채널 탄성파 탐사자료의 해석에 의하면 연구지역에 분포하는 플라이오-제4기 퇴적층은 침식부정합면에 의해 구분되는 9개의 퇴적단위가 중첩된 형태로 구성되어있다. 탄성파 단면상에서 각 퇴적단위는 남쪽사면의 경우 질량류 퇴적층으로 해석되는 캐오틱한 음향상 특징이 주로 나타나며, 북쪽 중앙분지로 향하면서 저탁류/반원양성 퇴적층으로 해석되는 연속성이 양호하고 진폭이 강한 평행 층리 음향상이 나타난다. 퇴적단위의 분포 및 탄성파상 특징에 의하면 플라이오-제4기 동안의 퇴적작용은 주로 지구조 운동과 해수면 변동에 의해 조절된 것으로 해석된다. 플라이오세 동안의 퇴적작용은 주로 동해의 닫힘작용과 연계된 지구조 운동의 영향이 있었다. 중-후기 마이오세 이후 동해는 횡압력에 의한 닫힘작용이 시작되었으며 플라이오세 말까지 횡압력의 영향으로 광역적인 융기가 야기되었다. 따라서 이때 형성된 다량의 침식 퇴적물이 분지로 유입되었으며 주로 쇄설류로 구성된 퇴적단위 1을 형성하게 되었다. 제4기에 접어들면서 중첩된 형태로 분포하는 퇴적단위 2-9의 발달은 주로 주기적으로 반복되는 해침과 해퇴의 영향에 의해 조절되었다. 반복적으로 진행된 해퇴 및 저해수면 조건이 주로 남쪽사면을 중심으로 분포하는 쇄설류의 퇴적을 야기시켰으며, 해수면 상승기간 동안에는 쇄설류 층이 얇은 반원양성 내지는 원양성 퇴적물에 의해 피복되었다. 결과적으로 연구해역에 분포하는 플라이오-제4기 퇴적층은 쇄설류와 저탁류/반원양성을 포함하는 질량류의 중첩에 의해 구성된다. Analysis of multi-channel seismic reflection data from the Southern Ulleung Basin reveals that Plio-Quaternary section in the area consists of nine stacked sedimentary units separated by erosional unconformities. On the southern slope, these sedimentary units are acoustically characterized by chaotic seismic facies without distinct internal reflections, interpreted as debris-flow bodies. Toward the basin floor, the sedimentary units are defined by well-stratified facies with good continuity and strong amplitude, interpreted as turbidite/hemipelagic sediments. The seismic facies distribution suggests that deposition of Plio-Quaternary section in the area was controlled mainly by tectonic movement and sea-level fluctuations. During the Pliocene, sedimentation was mainly controlled by tectonic movements related to the back-arc closure of the East Sea. The back-arc closure that began in the Miocene caused compressional deformation along the southern margin of the Ulleung Basin, resulting in regional uplift which continued until the Pliocene. Large amounts of sediments, eroded from the uplifted crustal blocks, were supplied to the basin, depositing Unit 1 which consists of debris-flow deposits. During the Quaternary, sea-level fluctuations resulted in stacked sedimentary units (2-9) consisting of debris-flow deposits, formed during sea-level fall and lowstands, and thin hemipelagic/turbidite sediments, deposited during sea-level rise and highstands.

보문 : 동안 이미지 연출을 위한 얼굴관리 및 시술 경험에 관한 연구

조민희 ( Min Hee Cho ),양진희 ( Jin Hee Yang ) 대한미용학회(구 대한미용과학회) 2015 대한미용학회지 Vol.11 No.1

In this study, a survey was administered to women in their 20s to 50s in order to assess their experiences with medical procedures for the baby-face image effect, as well as their interest in baby-face effect cosmetics. With regard to the preferred image dependent on the perceiver’s characteristics, study results revealed that a natural image was the most preferred across the entire age spectrum. Differences across the age ranges were detected and showed that a sexy image was the most preferred amongst women in their 20s, while a natural image was the most preferred amongst women in their 30s, 40s, and 50s. The analysis of frequencies in receiving face management and medical procedures for a baby-face effect indicated that skin care was the most often received (n=160, 38%), followed by baby-face cosmetics (n=107, 25.4%). Additionally, 70 respondents (16.9%) had received Botox, 50 (11.9%) received fillers, 28 (6.7%) received self-fat implants, and five (1.2%) had received dark-circle removal services. Results also indicated a relationship between younger age and greater experience in receiving baby-face cosmetics, reflecting a tendency amongst women in their 20s to value this trend. Furthermore, women in the higher age spectrum possessed the most experience in medical procedures and skin care, revealing the importance they placed on the health of the skin itself, as opposed to more ostentatious image adjustments. With regard to the effects of appearance on their interest in baby-face cosmetics, women in their 40s considered skin appearance as most important, while women in their 30s considered lip appearance as most important, thus presenting a significant contrast in the age spectrum. These results revealed differences between the received forms of baby-face image augmentation and interest in this image, which were dependent on the characteristics of the receiver. Such results are anticipated to be used as practical guidelines in future considerations of how best to affect the baby-face image.

Subtyping of Brucella abortus isolates is epidemiologically important for monitoring of bovine brucellosis outbreaks. Pulsed-field gel electrophoresis (PFGE) is considered as a gold standard of molecular typing methods to study the DNA polymorphisms of bacteria. In this study, we analyzed using PFGE the DNA fragment profiles of B. abortus isolated in Gyeongbuk province from 1998 to 2006. The genomic DNA was digested with the restriction endonuclease Xba I, Xho I and Smi I followed gel electrophoresis. No distinguishable patterns of the genomic DNA digested with Xba I and Xho I were observed among the field isolates of B. abortus tested in this study. But Smi I restriction enzyme resulted in two PFGE patterns consisting of 13-15 bands that ranged in size from 33 to 668bp by standard marker. The cluster analysis by DNA fingerprinting software showed 93.75% similarity between two PFGE patterns. No different PFGE patterns were recognized among the isolates originated from various years, regions and cow breeds.

The interface between servers and clients and system management in the cloud computing environment is different from the existing computing environment. The technology for information protection. Management and user authentication has become an important issue. For providing a more convenient service to users, SSO technology is applied to this cloud computing service. In the SSO service environment, system access using a single key facilitates access to several servers at the same time. This SSO authentication service technology is vulnerable to security of several systems, once the key is exposed. In this paper, we propose a technology to solve problems, which might be caused by single key authentication in SSO-based cloud computing access. This is a distributed agent authentication technology using a multiple SSO agent to reinforce user authentication using a single key in the SSO service environment. For user authentication reinforcement, phased access is applied and trackable log information is used when there is a security problem in system to provide a safe cloud computing service.

조민희 ( Jo Min Hee ) 한국경찰학회 2019 한국경찰학회보 Vol.21 No.4

3만여 명을 넘어선 북한이탈주민들의 안정적인 정착문제는 북한이 탈주민 개인의 문제가 아니라 한국사회 전체가 해결해야 할 중요한 사회문제이며 정책과제이다. 물론 북한이탈주민들이 정치체제와 경제구조가 다르고 문화적 격차가 심한 한국사회에 적응하고 정착하는 것은 결코 쉬운 일이 아니다. 북한이탈주민들이 한국사회에 안정적으로 정착하기위해서는 북한에서 학습했던 가치관에서 벗어나 하루속히 한국사회의 가치와 문화를 습득할 수 있는 재사회화가 이루어져야 한다. 본 연구는 바로 이 같은 시각에서 현재 북한이탈주민들에게 실시되고 있는 재사화교육의 현황을 분석하고 보다 바람직한 재사회화교육의 방안을 제시하는데 연구목적을 두었다. 현재 북한이탈주민에 대한 재사회화교육은 하나원, 하나센터, 고용지원센터, 북한이탈주민 지원재단, 북한이탈주민지역협의회, 민간단체 등에서 이루어지고 있다. 이들 각 기관은 다양한 재사회화교육 프로그램을 통하여 북한이탈주민의 한국사회정착을 지원하고 있다. 이를 위하여 본 연구는 재사회화이론을 개관하고 재사회화 이론적 시각에서 각 기관의 북한이탈주민에 대한 재사회화교육 실태를 분석하였다. 이 같은 분석을 토대로 재사회화교육 프로그램의 강화방안을 제시하였다. The problem of stable settlement of defectors over 30,000 is not an issue of individual defectors but an important social issue and a policy issue to be solved by the entire Korean society. However, it is not easy for North Korean defectors to adapt to and settle in Korean society, which has a political system and an economic structure different from each other and has a wide cultural gap. In order for North Korean defectors to settled in the Korean society in a stable manner, it is necessary to resocialize the values and culture of Korean society. The purpose of this study is to analyze the current state of rehabilitation education and to suggest a better education for rehabilitation education. To this end, the socialization theory, the re-socialization theory, the political socialization theory, and the psycho cybernetics theory are analyzed and the present situation of the re - socialization education for the defectors is analyzed. Hana Won's re-socialization curriculum, Hana Center's vocational competency development training, vocational training and re-socialization of employment centers, employment support activities of the North Korean Defector Foundation, support for North Korean defectors' local council, settlement support for civil organizations, and re-socialization education. Based on this analysis, the reinforcement plan of re-socialization education program and the step-by-step re-socializat ion education program were suggested as alternatives for improvement of re-socialization education and training.

조민희(Jo, Min-Hee),이재민(Lee, Jae-Min) 용인대학교 무도연구소 2012 武道硏究所誌 Vol.23 No.1

최근 학교 내외에서 일어나는 학교폭력과 외부인에 의한 성폭력범죄는 심각하다. 이에 대한 정부 및 관련기관의 정책대안은 다양하게 마련되었다. 그러나 큰 성과를 거두지 못한 것이 현실이다. 이 연구의 목적은 CPTED 기법을 적용하여 안전한 학교를 조성하는데 있다. 안전한 학교는 CCTV 등의 물리적 요소, 배움터지킴이 등의 인적 요소, 그리고 안전 교육 프로그램 등의 요소가 함께 적용되어야 효과적으로 달성될 수 있다. 이 연구는 기본적인 CPTED 원리와 실천방안을 학교건축 특성에 맞게 정리하였다. 그리고 국내외 학교 범죄예방 관련 연구 및 사례를 분석하였다. 또한 전국에 걸쳐 실시되고 있는 배움터지킴이 제도의 문제점을 보완함으로써 가정과 학교, 경찰과 지역사회가 유기적으로 연계하여 방안을 모색하였다. 이러한 연구결과를 요약하면 다음과 같다. 첫째, 학교특성에 적합한 물리적 환경개선이다. 외부인에 대한 출입을 통제하고 출입문을 제외하고 들어올 수 없도록 보완되어야 한다. 그리고 CCTV를 학교의 환경적 특성에 맞게 설치하여 학생들의 비행 및 폭력발생을 감독해야 한다. 둘째, 학교의 안전을 위한 인적 인프라를 구축하는 것이다. 물리적 환경개선을 통한 일차적인 범죄예방과 더불어, 배움터 지킴이나 학교보안관 등을 적극 활용하여 범죄를 예방해야 한다. 셋째, 학교의 안전을 위한 교육 프로그램 개발이다. 안전교육프로그램의 효과성을 높이기 위해서는 실제상황과 유사한 사례들을 직접 체험하여 방법들을 모색해야 한다. 학교가 범죄로부터 안전한 공간이 되기 위해서는 CPTED의 기본원리인 자연적 감시, 자연적 통제, 영역성의 확보 등에 기반을 둘 필요가 있다. Recently, school violence in classroom or around school increases and sexual crimes against students committed by outsiders is regarded as social problem. In order to prevent theses crimes, governments and various institutes provide alternatives. Despite of the effort, no one can witness brilliant success yet. Given that background, the purpose of this study is to secure safety in school area through CPTED(crime prevention through enviornmental design). Safer school can be achieved by the well-organized combination of physical factors as CCTV, human resource, and education programs for safety. This study provides basic principles of CPTED and practical alternatives with views on the previous case studies. In addition, it points out the problems in school police systems and suggest solutions by building social network. The results are as follows. First, it is necessary to rectify the school environment. For example, unidentified people are not allowed to access school and only one entrance door should be established for effective surveillance. Additionally, establishing CCTV in appropriate way to school environment is important to prevent crime or accidents in school. Second, enlarging human resource is a vital role in safer school. Along with physical factors, school police officers are required to increase the efficiency for safety in school area. Third, it is important to appreciate education programs for students safety. Applying practical methods into the safety programs is indispensible as to raise the effectiveness as well as to prevent crime victimization.
