이경아,전영국,정종인 한국컴퓨터교육학회 2004 컴퓨터교육학회 논문지 Vol.7 No.6

지식 정보화 사회에 컴퓨터 교육은 날로 그 중요성이 증대되어 왔다. 그러나 현재 중학교에서 컴퓨터교육은 재량활동 영역의 선택과목으로 운영되고 있다. 이러한 선택운영은 컴퓨터 교과의 경시 풍조를 가져오고, 이러한 운영으로 인한 부적절한 수업시수는 컴퓨터 교육의 현실성과 실효성을 떨어뜨리고 있다. 따라서 본 논문에서는 현재 운영되고 있는 다양한 형태의 선택 과목 운영 방법들을 비교 분석하고, 운영방식에 따라 나타나는 여러 가지 문제점을 파악하였다. 이러한 문제점을 분석하여 컴퓨터과목을 운영할 때 가장 적합한 방법을 찾아내고 학교교육에서 컴퓨터과목이 효율적으로 운영될 수 있는 방안을 제안하고자 한다. It has been increased the importance of computer education for the knowledge information society. However day by day. But computer education is currently operated with elective subjects in discretion action scope in a middle school. These operation of elective subjects brings a tended to neglect computer course, and inappropriate class number operated from this operation deteriorates reality and efficacy of computer education. Therefore, this paper compared and analyzed various operation methods of elective subjects that have been currently operated and grasped various problems to appear according to operation methods. When computer subject is operated using results from analyzing these problems, we find the most suitable way and provide sufficient references to operate computer subject in school education.

고속의 실시간 MPEG-2/H.264 transcoding 구조 제안

홍용택,이경호,김진상,조원경 경희-다반 ASIC 설계교육센터 2006 경희-다반 ASIC센터 논문집 Vol.7 No.-

H.264 비디오 코딩 표준은 기존 비디오 코딩 표준에 비해 뛰어난 압축부호화 효율로 인해 차세대 비디오 표준으로 각광받고 있으며 H.264가 가진 잠재적인 영향력 때문에 오늘날 디지털 비디오 시스템의 주를 이루고 있는 MPEG-2 시스템을 대체할 것으로 보여진다. 현재 MPEG-2 시스템이 광범위하게 자리 잡고 있기 때문에 H.264 시스템으로의 완전한 이동은 다소 시간이 걸릴 것으로 예상되고, 따라서 트랜스코딩 기술이 중요하게 대두되고 있다. 트렌스코더는 디코더와 인코더를 포함한 구조이기 때문에 매우 많은 연산량이 요구되며 그 복잡도를 줄이는 것이 중요하다. 본 논문에서는 디코딩 과정에서 추출된 정보를 인코딩 과정에 재사용함으로써 복잡도를 줄이도록 하였고, 또한 H.264에서 연산량이 많은 부분들을 여러 가지 알고리즘을 통해 복잡도를 줄임으로써 보다 빠른 속도로 동작이 가능한 트랜스코더 구조를 제안하였다.

Objectives : This study was conducted to evaluate the reliability and the validity of the Korean version of the Scale to Assessment Unawareness of Mental Disorder (SUMD-K). Methods : The subjects were 55 schizophrenic patients between ages of 26 and 58 who were recruited from the psychiatric unit of the university hospital and the out-patient clinic. The SUMD-K and insight scale of PANSS were applied to the patients. Results : The range of inter-rater (Spearman's rho) of the general items of SUMD-K were .97-.98 on the current illness and .58-.98 on the past illness. The correlation coefficient between the sum and the general items of the SUMD-K showed high scores. The concurrent validity between SUMD-K and insight item of PANSS was high (scores between .59-.96). However,the reliability and the validity of the attribution items of symptoms showed low scores compared to the current symptoms. Conclusion : The SUMD-K was confirmed in its reliability and validity. It can be a useful clinician-rating scale for evaluating insight in schizophrenic patients as well as patients with other neuropsychiatric conditions.

An attenuated classical swine fever virus (CSFV), Suri strain, is a variant derived from a vaccine virus, LOM strain. This study was performed to elucidate the molecular biologcal properties of CSFV Suri strain, and to obtain the basic data for molecular epidemiological approaches for the disease. The truncated form of gp55 gene without the C-terminal trasmembrane domain, in size of 1,023bp, was amplified by RT-PCR and sequenced by dye terminator cyclic sequencing method, and inserted into BamHI site of pAcGP67B baculovirus vector, establishing a cloned pAcHEG plasmid. By the nucleotide sequences determined, 341 amino acid sequences were predicted. As compard the nucleotide and amino acid sequences of gp55 of Suri with the various CSFV, Suri strain showed the high homology over 99.1% with ALD and LOM strains, but comparably the lower homology with Alfort and Brescia. In comparison of amino acid sequence in variable domain of gp55 protein, the similar tendency of homology was observed. In hydrophobicity analysis, all of four CSFV strains revealed the analogous patterns of hydrophobicity. The numbers and locations of N-glycosylation site and cysteine residuse in gp55 were analyzed, those of Suri strain being coincident with ALD and LOM strains. The results suggest that gp55 in Suri strain has the high similarity to those in ALD and LOM strains in terms of the nucleotide and amino acid sequences and the functional properties of gp55 protein.

목적: 지역사회 획득 감염의 매우 흔한 원인균인 폐렴구균의 페니실린 및 다른 항균제에 대한 내성의 증가는 세계적으로 문제가 될 뿐 아니라 국내에서 더욱 큰 문제로 대두되고 있다. 본 연구는 항균제 내성 여부에 따른 폐렴구균 균혈증의 임상적 특성 및 위험 요인를 분석하여 항균제 내성의 임상적 의미를 조사하고자 시행되었다. 방법:1989년부터 1994년까지의 폐렴구균 균혈증 41례를 대상으로 하여 의무기록지를 조사하였다. 균주의 항균제 감수성 검사는 oxacillin 디스크 확산법으로 페니실린 내성 여부를 거사한 후, 한천 희석법을 이용하여 페니실린을 비롯한 11개의 항균제의 MIC (minimal inhibitory concentration)를 구하고 감수성 여부를 판정하였다. 결과: 41균주 중 68.3%가 페니실린에 대하여 내성(중등도 12.2%, 고도 56.1%)을 보였으며 다제내성률은 61%였다. 특히 소아에서는 100%(고도 88.2%)의 내성률을 보여 성인보다 내성률이 더 높았다. 페니실린 내성 균주는 대부분 다른 β-lactam 항균제에도 내성을 보였으며 특히 페니실린 고도 내성 균주는 cefotaxime, ceftriaxone에 대하여 100% 내성을 보였고 imipenem에 대해서도 95.5%의 중등도 내성률을 보였다. 혈청형은 19와 23이 많았고 그 외에 6이 있었다. 임상적 특성의 분석상 환자들의 연령분포는 3개월부터 82세까지였으며 기저질환을 가지고 있는 환자가 56%이었으며 지역사회 획득 감염이 71%였다. 균혈증의 일차감염원은 폐렴(22례, 54%)과 수막염(5례, 12%)이 가장 많았다. 페니실린 내성의 위험요인으로는 소아 연령만이 유의한 요인으로 분석되었다. 항균요법에 대한 반응을 볼 때 실패한 경우는 고도 내성 군의 20%에서만 있었으며 병원내 총사망률은 페니실린 감수성 군이 30%, 중등도 내성 군이 20%, 고도 내성 군이 13.6%로서 유의한 차이는 없었다. 결론: 페니실린 내성 폐렴구균은 국내에 만연하고 있으며 높은 다제내성률을 보였다. 이들은 대개 지역 사회 획득 감염을 일으키는데 균혈증의 경우 그 사망률은 내성 여부에 따른 차이를 보이지 않았다. 소아연령만이 페니실린 내성의 위험요인으로 분석되었다. Background: The emergence of penicillin-resistant Streptococcus pneumoniae (PRSP) poses serious therapeutic problem in clinical practice, especially in cases with bacteremia or meningitis. Methods: To investigate clinical characteristics of bacteremic pneumococcal diseases due to PRSP, we retrospectively analyzed 41 cases with cocumented bacteremic diseases seen in a tertiary care hospital between 1989 and 1994. Results: Agar dilution test of 41 strains isolated showed that 68.3% of S. pneumoniae were PRSP [high-level resistance(R) 56.1%, intermediate resistance(I) 12.2%]. High-level resistant strains were not susceptible to other β-lactam agents, whereas isolates of penicillin-susceptible S. pneumoniae(PSSP) were uniformly susceptible to all β-lactam agents. Predominant serogroups of PRSP were 19, 23, and 6. Bacteremic diseases caused by PRSP included pneumonia (22), meningitis (5), peritonitis (3), acute otitis media (2), acute tonsillitis (2), endocarditis (1), pyelonephritis(1), and primary bacteremia(5). Children were more likely to be infected with PRSP with high-level or intermediately resistant strains than were adults(P=0.0001), but no differences were seen between PRSP and PSSP regarding sex. previous antibiotic history, previous hospitalization, and underlying immunocompromised conditions. Most cases were community-acquired (R 78.3%, I 60%, S 61.5%). Fatality rates of patients infected with PRSP were not different significantly from PSSP (22.6% vs. 30%). However, most fatal cases had underlying immunocompromised conditions. Conclusion: PRSP is widely prevalent in Korea and shows resistance to most antibiotics. It causes community-acquired bacteremic diseases with poor outcomes, but there was no difference in mortality between patients infected with PRSP and PSSP. Pediatric age was the only risk factor for penicillin resistance.

Integrated Risk Management for Automated Driving

Jun-Yung Lee,Beom-Jun Kim,Kyong-Su Yi 제어로봇시스템학회 2014 제어로봇시스템학회 국제학술대회 논문집 Vol.2014 No.10

This paper presents a model predictive control (MPC) approach to control a steering angle in an autonomous vehicle. In designing an automated driving control algorithm, probable risky driving situations should be considered to ensure vehicle safety. In order to guarantee safety to the possible change of traffic situation surrounding the subject vehicle, probabilistic future states of surrounding vehicles are predicted. The probabilistic behavior characteristics are analyzed based on driving data collected on a real road. Then a safe driving envelope which describes the driving condition for safety during a finite time-horizon is defined in consideration of the probabilistic prediction of future positions of surrounding vehicles. At each time step, MPC based controller computes the desired steering angle to keep the subject vehicle in the safe driving envelope during a finite time-horizon. The effectiveness of the proposed control algorithm is evaluated via computer simulation results and experiment results on a real vehicle.

Objective North Korean defectors (NKDs) have experienced substantial difficulties during the migration and settlement in South Korea. They have a high prevalence of depression, post-traumatic stress disorder, and suicidal behaviors. The high prevalence of mental disorders among NKDs can lead to a high suicide rate. However, there are no suicide prevention programs for NKDs. This study aims to customize a suicide prevention program with content suitable for NKDs’ particular circumstances.Methods A multidisciplinary research team developed this program based on domestic and international gatekeeper training programs for suicide prevention and articles related to suicide prevention.Results We developed a multi-part gatekeeper training program, “Suicide CARE for NKDs.” In the “Introduction,” trainees learn about the need for the program and its importance. In “Careful observation,” trainees learn to recognize linguistic, behavioral, and situational signals of suicide risk. In “Active listening,” trainees learn how to ask about suicidal thoughts and to listen empathetically. In “Risk evaluation and expert referral,” trainees learn to evaluate suicide risk and to connect NKDs with institutes or services.Conclusion We expect this program to become useful for training gatekeepers to prevent suicide among NKD. A future follow-up study is needed to confirm the efficacy of the program.
