In many applications researchers have been interested in implementation of Viterbi decoding algorithm for convolution codes. But it is problems that long constraint length codes need many storages and hardware implementation is complicated. In this paper, several stages of trellis diagram are integrated and this procedures are formulated into simple matrix operations. Also backtracking decoding procedures is eliminated. This algorithm is called a new Viterbi transform (VT) . The number of the trellis search can be reduced using the VT. Because of local memory access, the storages can be taken in. Long constraint length codes can be decoded by combining the unit module processors.

저자들은 1994년 1월 1일부터 1995년 6월 31일까지 가톨릭대학교 의과대학 의정부성모병원 정신과에 입원했던 환자들 중세서 공격행동을 보인 환자(공격군) 72명과 공격행동이 없었던 환자(비공격군) 215명의 임상적 특성에 관한 조사를 하여 다음과 같은 결과를 얻었다. 1) 공격행동을 보인 환자는 72명으로 전체 조사 환자의 25.1%이었다. 2) 성별, 연령, 종교, 결혼 상태와 정신과 질환의 가족력 등에 따른 공격행동의 발생비율의 차이는 유의하지 않았다. 3) 교육 정도와 직업에 따른 공격군의 비육에 유의한 차이가 있었다(p<.05). 4) 진단별로는 공격군에서 조증, 기질성 정신장애, 정신분열증의 빈도가 높았으나 진단에 따른 의미 있는 차이는 없었다. 5) 공격행동의 기왕력은 공격군에서 더 많았고 비공격군과 비교시 의미 있는 차이를 보였으며(p<.001), 입원 형태는 공격군에서 타의 입원의 빈도가 유의하게 높았다(p<.005). 7) 입원시 정신병리는 초조-흥분과 적대감-의심에서 공격군의 빈도가 높았으며 정신병리에 따른 의미 있는 차이를 보였다(p<.001). 8) 총 재원 일수는 공격군에서 평균 59.3일이었고 비공격군이 평균 38.4일로 유의한 차이를 보였다(p<.001). 9) 공격행동의 유형은 말로한 경우가 가장 많았고 물건을 대상으로한 행동, 타인을 대상으로 하는 행동의 순으로 나타났다. 10) 공격행동 직전 행동 특징은 활동증가, 시끄러움, 욕설, 분노, 적대적이었던 경우가 가장 많았다. 11) 공격행동은 정오에서 오후 6시 사이, 휴식시간에 가장 많이 나타났다. 12) 입원 후 1주일 이내에 공격행동의 62.3%가 나타났다. 13) 총공격 점수에 의미 있게 영향을 주었던 변인들로는 종교(p<.05), 교육 정도(p<.05), 직업(p<.05), 입원형태(p<.005), 진단(p<.001), 입원시 정신 병리(p<.001), 공격행동의 기왕력(p<.001) 등으로 나타났다. To evaluate the characteristics of violent behavior of psychiatric inpatients the authors reviewed clinical records of psychiatric patients who had admitted at UiJong Bu St. Mary's Hospital from January 1994 to June 1995. We divided the 287 subjects into violent and nonviolent group according to the presence of violent behaviors in psychiatric ward. We assessed demographic variables, clinical characteristics and violent behaviors using Overt Aggression Scale and compared these variables of violent group with nonviolent group. The results were as follows : 1) The number of violent patients was 72(25.1% of the total). 2) In terms of demographic variables, the differences between two groups in education and occupation were significant(p<.05). 3) In psychiatric diagnoses, violent group were more likely to have mania, schizophrenia and organic mental disorder in sequence but there were no differences between violent and nonviolent group. 4) The history of violent behavior was greater in violent group(p<.001) and the mode of admission was significantly different between two groups(p<.005). 5) In cluster of psychopathology on admission, more frequently found clusters of psychopathology in violent group were agitation-excitement and hostile- suspiciousness and there were significant differences between two groups(p<.001). 6) The length of stay in violent group(59.3 days)was significantly longer than nonviolent group(38.4 days)(p<.001). 7) The types of violent behavior were verbal aggression, physical aggression against objects and physical aggression against other people in frequency sequence. 8) The most frequent type of behavioral clue before violent behavior was hyperactive, loud, verbally abusive, angry, hostile(68.1%). 9) Most of violent behaviors were presented between midday and 6 pm. in resting time. 10) 62.3% of total violent behaviors were occurred within first week following admission. 11) The variables which showed significant effects on total aggression score were religion, educational status, occupation, mode of admission, psychiatric diagnosis, psychopathology on admission and history of violent behavior before admission. In summary, these results showed similar trends compared to previous studies on characteristics of psychiatric inpatients. And we found that more important predictors of violent behavior in practice were likely to be history of violent behavior, psychopathology on admission and behavioral cue before violent behavior.

Background: Ginseng (Panax ginseng Meyer) is an important medicinal herbs in Asia. However, ginsengvarieties are less developed. Method: To developed ginseng varieties, a pure line selection method was applied in this study. Results: Gumpoong was testing of 4-yr-old specimens in 2002, the proportions of the below-groundroots that were rusty colored for Gumpoong was 1.29 in Daejeon and 1.45 in Eumseong, whereas theproportions for its yellow berry variant were 2.60 and 2.45 in the two regions, respectively. Thus theGumpoong was resistant to root rust. Sunpoong has a high yielding property. Its average root weight is70.6 g for 6-yr-old roots. Its yield is 2.9 kg/1.62m2 and the rate of heaven- and earth-grade product is20.9%, which is very high compared to 9.4% for Yunpoong. Sunone is resistance to root rot and thesurvival rate of 4-yr-old roots was 44.4% in 1997, whereas that of the violet-stem variant landrace was21.7%. Sunhyang has content of arginyl-fructosyl-glucose (AFG), which produces the unique scent of redginseng, is 95.1 mmol/g and greater than the 30.8 mmol/g of Chunpoong in 6-yr-old plants. Sunun andCheongsun are being nurtured to protect genetic resources. Conclusion: Developed ginsneg varieties will be used as the basis for the protection of genetic resourcesand breeding. Jang-Ho Lee

장상용,윤준선,백준홍 대한건축학회 2004 대한건축학회 학술발표대회 논문집 - 계획계/구조계 Vol.24 No.1

The propose of this study is to present the possible solutions for the shortage of skilled labor in Korean construction industry that is currently encountered. This study examined employment trends in construction industry in Korea and U.S.A. The construction industry is highly influenced by economic cycle. The aging of the crafts and shortage of workers are pressing issue in this industry. In order to solve this problem, The construction industry must lead women labor to enter the their industry with appropriate education. This answer to the shortage is to retain those workers currently worked in other industry and to streamline construction practices to reduce labor strain.

MPLS 네트워크의 레이블 할당 정책 비교 및 시뮬레이션 방법 연구

장성식 ; 김용준 김천대학교 1999 김천대학교 논문집 Vol.20 No.-

A IETF working group proposed the MPLS technology that performs high speed switching using a dedicate hardware because increasing Internet Services require gast transmission of various types of traffic. MPLS utilizes the bandwidth of physical links maximally and supplies QoS, scalability and traffic engineering easily. Because this technology, however, was not standardized yet, various policies have been presented. In this paper, we compared existing.

Voltatile flavor components in salt-fermented Gizzard shad were analyzed by simultaneous steam distillation-solvent extraction gas chromatography/mass spectrometry. One hundred compounds were detected in sample. These compounds were composed mainly of aldehydes(15), ketones(14), alcohols(18), aromatic compounds(7), N-containing compounds(9), esters(15),S-containing compounds(8) and miscellaneous compounds(14). The alcohols were the large amounts in the number of flavor compounds detected in sample. But these compounds may not have an impact on sample flavor because of their high flavor thresholds. The flavor compounds such as aldehydes, ketones, N-containing compounds, esters and S-containing compounds were supposed to be playing a major role in salt-fermented Gizzard shad.

CGI 프로그램에서 클라이언트와 서버의 자동화된 상태정보 전달

최준용,유진호,장종표,방만원 木浦大學校 情報産業硏究所 1997 情報産業硏究誌 Vol.5 No.-

The HTTP Protocol composed of WWW's client/server model is unconnected and not keep state, so, there is one connection for one request. In this condition, it has no guarantee to memory which is needed in sequential processing, and HTTP Protocol has no choices to transfer the information from client to server's CGI or the information exchange. This paper uses the word 'key' instead of this 'state information'. We studied the key which creates automatically the HTML document for data search hierarchically in WWW environment and to confirm applied this to multimedia order and sale system of agricultural and marine products.
