The purpose of this study is to analyze the career consciousness of Jeju university students and to provide basic materials which can help them to understand the career guidance as well counseling. The data was obtained through the survey asked a number of senior and junior students at Jeju university in December 2008. The information gathered, which resulted in 223 responses that have been used in the study, was analyzed by frequency using SPSS/PC 12.0 program. The results of this study are the following: First, we need to provide specific career information and practical education to help the student employment and to increase the interest of students in major by strengthening the major training course. Second, we need to provide specific and systematic career counseling system. Even though students have various ideas of their career, they do not effort any preparation to get their own job. To tell the truth, they do not have a mind of concrete career. They just collect some information related to the job or are interested in seeking information of career. Actually, they do not have enough confidence to get job because of lack of aptitude and desire about their career. Students do not have the necessary know-how for the employment, therefore they need to be offered systematic information from the university, which is requested the thoughtful consideration of finance and policy in order to quickly adjust themselves to their environment, character and interest. Third, various career counseling programs need to be developed and applied to each student to prepare an opportunity for employment according to their learning stages. The field of support needs to expand increase of job preparation education, English education, humanity or sociality programs, drawing up resume and the interview training course. Fourth, we need to develop various programs considering necessity and specific of each college. Fifth, it seems to be a different approach according to gender. Girls in university have been relatively eager to have job-seeking than boys. However, their preparation level and motivation are generally low. Colleges' career support system and organization utility have been uneffective because their programs have been not specified for women. It is important to offer various counsel and guidance to women. Sixth, a professor of college emphasized to increase career counsel with their students because it would give an important solution for students to have job-seeking. In addition, possible follow-up projects are proposed in the limitations of the study.

Until recently, colorectal polyps were classified predominantly as hyperplastic or adenomatous. While adenomatous polyps are well-characterized precursor lesions of adenocarcinomas, hyperplastic polyps have been considered as benign lesion. However, some hyperplastic polyps with serrated morphology of the crypts have been recognized to have distinctive features and these polyps were termed ‘serrated adenomas’. Recent data show that sessile serrated adenomas (SSA) might be the precursors of serrated colonic cancers, underlining the necessity of identifying them. SSA is approximately 3% of all polyps, commonly appears as flat or sessile and yellowish due to mucus production. In the pathogenesis of SSA, progression to high grade dysplasia or early invasive carcinoma may be associated with serrated neoplasia pathway different from adenoma-carcinoma sequence. We report a case with a colon polyp diagnosed as sessile serrated adenoma with high grade dysplasia after endoscopic submucosal dissection.

In this paper, the result of application of vibration method to the orthotropic plates with free edges supported on elastic foundation and with a pair of opposite edges under axial forces is presented. Such plates represent the concrete highway slab and hybrid composite pavement of bridges. The reinforced concrete slab can be assumed as a special orthotropic plate, as a close approximation. The highway slab is supported on elastic foundation, with free boundaries. Sometimes, the pair of edges perpendicular to the traffic direction amy be subject to the axial forces. The plate is subject to the concentrated load/loads, in the form of traffic loads, or the test equipments. Finite difference method is used to obtain the deflection influence surfaces needed for vibration analysis. The influence of the modulus of the foundation, the aspect ration of the plate, and the magnitudes of the axial forces and the concentrated attached mass on the plate, under the natural frequency is thoroughly studied.

WATM (Wireless ATM) 망에서는 단말이 이동하는 동안 핸드오프(handoff)와 리라우팅(rerouting)이 실행된다. 이때, 지연 시간이 발생하는데 시간에 민감한 동화상 데이터는 사용자의 실시간 QOS(Quality Of Service)를 보증해야 한다. 본 논문에서는 기존의 핸드오프 방식과 rerouting 방법과 bufferring 방법을 알아본다. 그리고 기존의 rerouting 방법 중 NCNR(Nearest Common Node Rerouting) 기법을 사용하여, 시간에 민감한 트래픽(NCNR-TS)인 비디오 부분의 트래픽을 분석한다. Wireless ATM의 특징인 ATM 네트웍의 유선망과 연동을 통해 MPEG 데이터의 특성을 이용하여 무선 ATM 망의 Wireless-to-ATM Network Interface에서 우선순위로 버퍼링을 행하는 우선순위 버퍼링 기법을 제안한다.

최근에 멀티미디어 콘텐츠의 전송이 활성화 되고 있다. 이는 인터넷을 통하여 배포되는 멀티미디어 콘텐츠가 상업성을 갖게되는 발판이 되었다. 그러나, 이러한 멀티미디어 컨텐츠는 복사가 자유롭기 때문에 워터마킹 기법만 사용하는 경우에는 상업적으로 사용되기에 많은 취약성을 가지고 있다. 따라서 본 논문에서는 스테가노그래피 기법을 이용하여 멀티미디어 콘텐츠를 보호하기 위한 안전한 DRM 시스템을 제안한다. 본 DRM 시스템은 워터마킹 기술과 스테가노그래피 기술의 특이점을 보강하여 일반적인 DRM 시스템보다 더 강력하다. 따라서, 본 시스템을 통하여 사용자 인증 뿐만 아니라 멀티미디어 콘텐츠의 불법복제 및 불법도용을 방지할 수 있다. Transferring the contents for multimedia shows recently very activity. So this fact allows the contents for multimedia to be commercialized. These contents, however, included much vulnerability that it is difficult to be commercialized because attackers easily reproduce that. Many developers want to use watermarking method as the technique to protect the contents for multimedia, but it is very vulnerable to use only one method. This paper proposes the Secure DRM system which protects the contents for multimedia steganography methods. The DRM system is more powerful than general DRM systems in that it has the special feature of watermarking and steganography techniques. We can prevent the attackers from reproducing and stealing the contents illegally, and authenticating users through DRM systems.

Kyoung Hwa Ha,Kyung Ae Lee,Kyung-Do Han,Min Kyong Moon,Dae Jung Kim 대한내과학회 2023 The Korean Journal of Internal Medicine Vol.38 No.1

Background/Aims: The Korean Diabetes Association (KDA) guidelines recommend adults aged ≥ 40 years and adults aged ≥ 30 years with diabetes risk factors for diabetes screening. This study aimed to determine the age threshold for diabetes screening in Korean adults. Methods: This study was based on the analyses of Korean adults aged ≥ 20 years using the Korea National Health and Nutrition Examination Survey (KNHANES) and the National Health Insurance Service-National Sample Cohort (NHIS-NSC). To evaluate screening effectiveness, we calculated the number needed to screen (NNS). Results: NNS to detect diabetes decreased from 63 to 34 in the KNHANES and from 71 to 42 in the NHIS-NSC between the ages of 30–34 and 35–39. When universal screening was applied to adults aged ≥ 35, the NNS was similar to that of adults aged ≥ 40. Compared to the KDA guidelines, the rate of missed screening positive in adults aged ≥ 20 decreased from 4.0% to 0.2% when the newly suggested screening criteria were applied. Conclusions: Universal screening for adults aged ≥ 35 and selective screening for adults aged 20 to 34, considering diabetes risk factors, may be appropriate for detecting prediabetes and diabetes in South Korea.

Multidrug resistance, especially multidrug efflux mechanisms that extrude structurally unrelated cytotoxic compounds from the cell by multidrug transporters, is a serious problem and one of the main reasons for the failure of therapeutic treatment of infections by pathogenic microorganisms as well as of cancer cells. Streptococcus mutans is considered one of the primary causative agents of dental caries and periodontal disease, which comprise the most common oral diseases. A fragment of chromosomal DNA from S. mutans KCTC3065 was cloned using Escherichia coli KAM32 as host cells lacking major multidrug efflux pumps. Although E. coli KAM32 cells were very sensitive to many antimicrobial agents, the transformed cells harboring a recombinant plasmid became resistant to several structurally unrelated antimicrobial agents such as tetracycline, kanamycin, rhodamin 6G, ampicillin, acriflavine, ethidium bromide, and tetraphenylphosphonium chloride. This suggested that the cloned DNA fragment carries a gene encoding a multidrug efflux pump. Among 49 of the multidrug-resistant transformants, we report the functional gene cloning and characterization of the function of one multidrug efflux pump, namely MdeA from S. mutans, which was expressed in E. coli KAM32. Judging from the structural and biochemical properties, we concluded that MdeA is the first cloned and characterized multidrug efflux pump using the proton motive force as the energy for efflux drugs.

최근 다양한 형태의 클라우드 컴퓨팅 서비스의 출현으로 인한 가상화 기술이 급부상 하면서 데이터에 대한 안전성과 신뢰성 등 보안 문제가 이슈화되고 있다. 클라우드 서비스의 가상화 계층의 손상은 모든 호스트(사용자) 업무의 손상을 가져올 수 있기 때문에 복수의 가상 운영체제가 구동될 수 있는 환경을 제공하는 하이퍼바이저는 해커들에 의해 공격 대상이 될 수 있다. 본 논문에서는 가상화 기술인 하이퍼바이저(베어 메탈 기반)에 해킹 및 악성코드에 예방을 위한 보안 구조를 제안한다. With rapid rise of virtualization technology from diverse types of cloud computing service, security problems such as data safety and reliability are the issues at stake. Since damage in virtualization layer of cloud service can cause damage on all host (user) tasks, Hypervisor that provides an environment for multiple virtual operating systems can be a target of attackers. This paper propose a security structure for protecting Hypervisor from hacking and malware infection.
