데이터 연관은 지능시스템의 자율적인 작동에 매우 중요한 문제이다. 본 논문에서는 데이터 연관 문제를 Bayesian 방식으로 구성하고 이를 성공적으로 지능시스템에 응용한 예를 설명한다. 먼저 데이터 연관 문제가 어떻게 Bayesian 방식으로 구성하여 혼잡한 환경에서의 다 물체 추적 문제에 적용되는지 알아본다. 그리고 데이터 연관이 지능시스템에 어떻게 응용될 수 있는지 정체 관리를 이용한 항공 교통 관제, 카메라 네트워크 위치 및 관점 자동 보정, 멀티 센서 퓨젼의 세 가지 예를 이용해 살펴본다. Data association plays an important role in intelligent systems. This paper presents the Bayesian formulation of data association and its applications to intelligent systems. We first describe the Bayesian formulation of data association developed for solving multi-target tracking problems in a cluttered environment. Then we review applications of data association in intelligent systems, including surveillance using wireless sensor networks, identity management for air traffic control, camera network localization, and multi-sensor fusion.

Purpose: The aim of our study was to investigate the characteristics of the peritoneal dialysis (PD) - related peritonitis and to evaluate the effectiveness of the empirical antibiotics recommended by the International Society for Peritoneal Dialysis in Korean children. Methods: We retrospectively reviewed the medical records of 72 children on peritoneal dialysis at the Department of Pediatrics, Asan Medical Center over the period from March 2000 to February 2012. Results: Seventy-nine episodes of peritonitis occurred in 32 patients. The incidence of peritonitis was 0.43 episodes/patient year. There were no significant differences in the incidence of peritonitis in terms of dialysis modality (P=0.459). Twenty-one patients experienced 51 catheter exit-site infections (0.28 episode/patient year). There were no significant differences in the incidence of peritonitis between those with and without history of exit-site infections (P=0.721). Specific pathogens were isolated from 68.4% (54/79) of the patient with peritonitis episodes, including Gram-positive bacteria (n=34), Gram-negative bacteria (n=25) and fungus (n=1). Among Gram-positive bacteria, 85.3% of the isolates were susceptible to ${\beta}$-lactam antibiotics, among Gram-negative rods, 94.7% of the isolates were susceptible to ceftazidime. Among 25 cases with unknown etiologies, 92.0% of cases demonstrated satisfactory responses to cefazolin and ceftazidime. Conclusions: The incidence of peritonitis was 0.43 episodes/patient year. Initial empirical therapy consisting of cefazolin and ceftazidime was appropriate for 91.1% of the PD-related peritonitis treatment. Continuous monitoring for the emergence of the resistant organisms is an important part of the appropriate managements of PD-related peritonitis. 목적: 소아 복막 투석 환자에서 복막염의 특징과 International Society for Peritoneal dialysis의 가이드라인에 따른 경험적 항생제 치료가 적절한지 분석하였다. 방법: 2000년 3월부터 2012년 2월까지 서울아산병원 소아과에서 복막 투석을 한 경험이 있는 72명의 환자들을 대상으로 의무기록을 후향적으로 분석하였다. 결과: 복막 투석을 받은 32명의 환자에서 79회의 복막염이 발생하여 발생빈도는 0.43회/환자 년이었고 복막 투석 방식에 따른 복막염의 발생 빈도는 차이가 없었다(P=0.459). 또한 21명의 환자가 51회의 복막 도관 감염을 경험하였고 도관 감염의 발생 빈도는 0.28회/환자 년이었다. 복막 도관 감염에 따른 복막염의 발생 빈도는 차이가 없었다(P=0.721). 79회의 복막염 중 68.4%에서 균이 동정되었으며, 그람 양성균 중 85.3%가 ${\beta}$-lactam계 항생제에 감수성이 있었고 그람 음성 막대균 중 94.7%가 ceftazidime에 감수성이 있었다. 균이 동정되지 않은 복막염 중에는 92.0%에서 cefazolin과 ceftazidme에 치료 반응을 보였다. 결론: 복막 투석 환자에서 복막염의 발생 빈도는 0.43회/환자 년이었고, 복막염에 대한 치료로 cefazolin과 ceftazidime의 초기 경험적 항생제 투여는 복막염의 91.1%에서 적절하였다. 그러나 내성 균주에 대한 지속적인 감시가 필요하다.

In the past, Anseong was a hub where many people gathered as the market was active as trains and waterways passed. However, it declined sharply after the waterway and market disappeared. Based on these historical factors, the restoration project of Anseong City was carried out, but the project was not successful and Anseong did not restore its former glory. Therefore, this study tried to make Anseong into a historical tourism complex based on this historical fact and historical factors because Anseong was also the birthplace of the national independence movement in the past.

이 연구의 목적은 경찰 직무스트레스 해소 프로그램을 위한 범이론적 모델(TTM)을 이용한 직무스트레스 관리에 관련된 변인을 분석하는데 있다. 표집대상은 인천광역시 경찰관 280명(남 240명, 여 40명)이었다. 측정도구는 박영신과 김의철(2009)이 제작한 것을 사용하였으며, 신뢰도는 Cronbach α= .66~.93으로 양호하였다. 분석결과는 다음과 같다. 첫째, 경찰관의 배경정보와 직무스트레스의 상관관계를 분석한 결과, 사회계층이 낮을수록, 직업성취도가 낮을수록, 직업에 대한 회의가 있을수록 직무스트레스가 높았다. 학력이 높을수록, 가족과 거주하지 않을수록, 근무경력이 적을수록 일반 스트레스증상(RISCI)이 높았다. 둘째, 사회적 지원과 직무스트레스의 상관관계를 분석한 결과, 직장상사로부터 정서적 지원을 적게 받을수록 직무스트레스가 높았다. 가족으로부터 정서적 지원을 적게 받을수록 우울증이 높았다. 셋째, 경찰관의 성격 및 자기효능감과 직무스트레스의 상관관계를 분석한 결과, 외향적이고 친화적이며, 정서적 안정성이 높을수록 직무스트레스가 낮았다. 또한 자기효능감이 높을수록 직무스트레스가 낮았다. 정서적 안정성이 높을수록 스트레스 증상(RISCI)과 우울증이 낮았다. 자기효능감이 높을수록 스트레스에 잘 대처하고 우울증이 낮았다. The purpose of this research analyzes the factor related to the job stress management using the theoretical model(TTM) for the police job stress settlement program. A total of 280 policeman(male 240, female 40) at Inchon Metro-Politan City have been recruited. They completed the question which has been developed by Park & Kim(2009). The reliability of the questionnaire was Cronbach α=.66~.93. The results are as follows. First, correlation between background information and stress of policeman have been examined. Policeman showed high level of job related stress when they had lower status, lower occupational achievement, and more being skeptical for their job. And also they showed high level of general stress symptoms(RISCI) when they have high attainments in scholarship, low career in job, and they did not live with family. Second, correlation between social support and stress of policeman have been examined. Policeman showed high level of job related stress when they received less emotional support from their boss. On the other hand, policeman showed high level of depression when they received less emotional support from their family. Third, correlation between personality, self-efficacy and stress of policeman have been examined. Policeman showed low level of job relatedstress when they were extrovert, friendly, emotionally stable in personality characteristics, and they have high self-efficacy. Also, policeman showed low level of general stress symptoms(RISCI) and depression when they were emotionally stable in personality characteristics, and they have high efficacy beliefs.

Objective: To investigate the relationship between placental pathology and neurodevelopmental outcomes among extremely low birth weight (ELBW) infants Methods: Pathology of placentas from ELBW infants born at a tertiary neonatal intensive care unit from January 2007 to December 2012 were reviewed and placental histology was grouped into 3 categories by a designated pathologist: acute chorioamnionitis (ACA), maternal vascular underperfusion (MVU), and control group. Matched ELBW infants were tested for significant neurodevelopmental delays defined as mental developmental index (MDI) or psychomotor developmental index (PDI) <70, using Bayley Scales of Infant Development-II (BSID-II). Results: The mean gestational age and birth weight of 175 infants were 27.1±2.5 weeks and 764.7±152.3 g respectively. Placental histology revealed MVU (48.0%), ACA (25.1%) and control (26.9%) in distribution. There were less significant patent ductus arteriosus in MVU group than in control group [adjusted odds ratio (OR)=0.331, P=0.011]. The frequencies of other neonatal diseases and mortality were similar in 3 groups. Sixty four of 175 infants were examined for BSID-II at mean corrected 19.9±3.2 months. MVU was associated with significant mental developmental delay (OR=5.185, P=0.036), but after adjustment for head circumference/weight at birth, the statistically significance of association disappeared (adjusted OR=4.391, P=0.075). ACA did not affect neonatal and neurodevelopmental outcomes. Conclusion: The result of placenta biopsy could be a useful tool in counseling parents for future neurodevelopmental outcome, however, further studies are required to define definitive association in between placenta biopsy and neurodevelopmental outcomes.

목 적: 본원 신생아실 및 신생아 중환자실에서 10년간 발생한 신생아 패혈증을 조사하여 환아들의 특징, 패혈증의 원인균 및 항생제 감수성의 변화를 파악하고 신생아 패혈증을 치료하는데 도움되고자 하였다. 방 법: 1989년부터 1998년까지의 10년간 본원 신생아실 및 신생아 중환자실에 입원하였던 환아 15,144명에 대해 의무기록을 확인하여 신생아 패혈증으로 진단된 환아를 선별하였다. 조사 기간을 1989년부터 1993년까지(전반기)와 1994년부터 1998 년까지(후반기)로 나누어 패혈증으로 진단된 환아 들의 임상적 특징, 균의 종류와 빈도, 항생제 감수성의 변화 양상을 관찰하였다. 결 과 : 신생아 패혈증은 총 15,144명 중 170명에서 진단되어 1.1%(전반기 91명, 1.2%, 후반기 79명 1.0%)이었으며, 186회(전반기 99회, 후반기 87회)에 걸쳐 200개의 균주(전반기 109균주, 후반기 91균주)가 분리동정 되었다. 평균 발병시기는 생후12.3일로 전반기 8.8일, 후반기 16.3일이었고, 조발형은 전반기 34.7%, 후반기 23.0%로 나타나 전반기에 더 빨리 발병하였다. 분리된 균주는 그람양성균 132회 (66.0%), 그람음성균 60회(30.0%), 진균 8회(4.0%)이었으며, Coagulase negative Staphylococcus(CNS)가 총 69회(34.5%)로 가장 많은 빈도를 나타내었고, Staphylococcus aureus(S. aureus) 36회(18.0%), Klebsiella pneumoniae(K. pneumoniae) 17회(8.5%), Enterococcus 12회(6.0%), Enterobacter cloacae(E. cloacae) 8회(4.0%), Escherichia coli(E. coli) 6회(3.0%), Pseudomonas aeruginosa(P. aeruginasa) 5회(2.5%) 등의 순이었다. 진균으로는 Candida parapsilosis, Candida albicans, Trichosporon pullulans 가 분리되었다. CNS, S. aureus 및 Acinetobacter baumannii(A. baumanii), Candida는 전반기에 비해 후반기에 더 많이 분리 동정되었으며, CNS 및 S. aureus의 methicillin 및 1세대 cephalosporin에 대한 항생제 감수성은 전반기에 비해 후반기에 감소하였고 aminoglycosides에 대한 감수성은 후반기에 증가하였으며, vancomycin 내성균은 분리되지 않았다. K. pneumoniae, Enterococcus, E. coli 및 P. aeruginosa는 전반기에 비해 후반기에 감소하였으며 K. pneumoniae는 1세대 cephalosporin에 대해 전, 후반기 모두 낮은 감수성을 보였고 tobramycin과 gentamicin에는 후반기에 감수성이 증가하였으며 amikacin, ceftriaxone, trimethoprim-sulfamethoxazole에는 전, 후반기 모두 높은 감수성을 보였다. Enterococcous는ampicillin, penicillin 및 1세대 cephalosporin에 대한 감수성이 후반기에 감소하였으나 vancomycin 내성균은 분리되지 않았다. 결 론 : 지난 10년간의 신생아 패혈증의 발생 빈도는 1.1%이었으며, CNS와 S. aureus가 신생아 패혈증의 주 원인균이었고, 일차 항생제에 대한 감수성은 전반기에 비해 후반기에 감소하였으나 vanco- mycin 내성균은 발견되지 않았다. 신생아 패혈증의 주요 원인균으로 알려진 group B Streptococcus는 발견되지 않았으며, K. pneumoniae에 의한 신생아 패혈증은 후반기에 더 많이 발생하였으나 항생제 감수성은 감소되지 않았다. Background : To delineate the changes in the causative agents of neonatal sepsis and their antimicrobial susceptibilities in the neonatal intensive care unit and nursery of Hanyang University Hospital during the past 10 years. Methods : Hospital records of 15,144 patients hospitalized at the NICU and nursery of Hanyang University Hospital from 1989 to 1998 were reviewed and neonates diagnosed of neonatal sepsis were sorted and included in the study. The study period was divided into Period A(the first 5 years) and Period B(the second 5 years) to analyse causative agents and their antimicrobial susceptibilities. Results : Neonatal sepsis was diagnosed in 170 patients(1.1%{Period A 1.2%, Period B 1.0%}) among the total of 15,144 inpatients. Two hundred isolates(Period A 109 isolates, Period B 91 isolates) were identified in 186 blood cultures(Period A 99 cultures, Period B 87 cultures) from 170 patients(Period A 91 patients, Period B 79 patients). The average age at the onset of the disease, when the initial blood culture was drawn, was 12.3 days old(Period A 8.8 days, Period B 16.3 days), and the proportion of the early onset disease was 34.7% in Period A and 23.0% in Period B, indicating that neonatal sepsis developed earlier during Period A. Among the isolated organisms including Gram positive bacteria[132(66.0%)], Gram negative bacteria [60(30.0%)], and fungi[8(4.0%)], coagulase negative Staphylococcus(CNS) was the most common organism(69/34.5%), followed by Staphylococcus aureus(36/18.0%), Klebsiella pneumoniae(17/8.5%), Enterococcus(12/6.0%), Enterobacter cloacae(8/4.0%), Escherichia coli(6/3.0%), and Pseudomonas aeruginosae(5/2.5%). The isolated fungi were Candida parapsilosis, Candida albicans, and Trichosporon pullulans. CNS, S. aureus and Acinetobacter baumannii were isolated more frequently in Period A compared to Period B. Antimicrobial susceptibilities of CNS and S. aureus to methicillin and the first generation cephalo sporins were decreased in Period B compare to Period A, those to aminoglycosides were increased in Period B, and vancomycin resistant strains were not identified. K. pneumoniae, Enterococcus, E. coli, and P. aeruginosa were isolated less frequently in Period B, compared to Period A. For K. pneumoniae, antimicrobial susceptibilities to the first generation cephalosporins were low in both Periods A and B, those to tobramycin and gentamicin were increased in Period B, and those to amikacin, ceftriaxone, and trimethoprim-sulfamethoxazole were high in both Periods A and B. Antimicrobial susceptibilities of Enterococcous to ampicillin, penicillin, and the first generation cephalosporins were decreased in Period B, but vancomycin resistant strains were not identified. Conclusion : The occurrence rate of neonatal sepsis during the past 10 years in the NICU and nursery of the Hanyang University hospital was 1.1%, and the most common causitive agents were CNS and S. aureus, to which the antimicrobial susceptibilities to the first line drugs decreased in the later half of the study period with no vancomycin resistant isolates identified. Group B Streptococcus known to be the most common agent causing neonatal sepsis was not identified, and K. pneumoniae was isolated more commonly during the later half of the study period without decreased antimicrobial susceptibilities.

저자들은 재태기간 26주에 조기 진통으로 분만 후 사망한 초극소 저출생 체중아에서 L. monocytogenes에 의한 패혈증과 이에 의한 사망을 관찰하였기에 이를 문헌 고찰과 함께 보고하는 바이다. Listeria monocytogenes is one of the important causes of neonatal sepsis and listerial neonatal infection manifests in two forms : Early-onset sepsis syndrome, associated with spontaneous abortion, still birth, preterm labor, granulomatosis infantiseptica, respiratory distress, sepsis, hemodynamic compromise and late-onset listerosis mainly associated with meningitis. Cases of neonatal listerosis reported in Korea have been rare and all were full term newborns. We, herein, report a case of early-onset sepsis due to L. monocytogenes in a extremely low birth weight infant who were born in a critical condition and succumbed in the second day of life despite the intensive care.

임우영,오성희,이승환,박영민,배성만,Im, Woo-Young,Oh, Seong-Hee,Lee, Seung-Hwan,Park, Young-Min,Bae, Seong-Man 대한생물정신의학회 2008 생물정신의학 Vol.15 No.3

Objectives : The purpose of this study is to compare the ability of facial affect perception among schizophrenia patients, their first degree relatives, and normal control subjects. Methods : Thirty five patients with schizophrenia, 22 first degree relatives, and 34 normal control subjects were recruited in this study. All three groups were matched for age and education levels. The facial affect identification test(FAIT), and neurocognitive test were applied. In the FAIT, the correct response rate, perceived intensity, and sensitivity for 6 kinds of affects were compared among three groups. Results : We found that correct response rate of sadness and anger were decreased in the schizophrenia patients compared with the normal control group. Also the schizophrenia patients showed reduced sensitivity for all six affects compared with the normal control group. The ability of facial affect perception in first degree relatives of schizophrenia patients was decreased but there were not any significant differences compared with normal control group. Conclusion : This study confirmed significantly reduced ability of facial affect perception in schizophrenia patients compared with normal control. Decreased ability of facial affect perception in first degree relatives suggests that affective sensitivity can be influenced by genetic predisposition.

주요 우울 장애, 정신분열병, 양극성 장애 및 정상 대조군에서의 N100 진폭경사

양은경,이승환,오성희,김상래,Yang, Eunkyoung,Lee, Seung-Hwan,Oh, Sunghee,Kim, Sangrae 대한생물정신의학회 2009 생물정신의학 Vol.16 No.3

Objectives : N100 amplitude slope(the intensity dependence of the cortical auditory evoked potentials) is widely considered as an indirect indicator of central serotonergic neurotransmission. However, there are only a few studies about N100 amplitude slopes of major psychiatric disorders. In this study, we examined N100 amplitude slope differences among major depressive disorder(MDD), bipolar disorder(BD), schizophrenia (SCZ) and normal controls(NC). Methods : We measured the N100 amplitude slopes of 35 patients with MDD, 33 patients with BD, 27 patients with SCZ and 35 NC subjects. Amplitude differences from N1 to P2 at the five different sound intensities(55, 65, 75, 85 and 95dB) were examined at Cz electrode. The N100 amplitude slope was calculated as the linear regression of five N1/P2 peak-to-peak amplitudes across stimulus intensities. Results : BD patients showed significantly reduced N100 amplitude slope compared with NC(0.54${\pm}$0.70 vs. 0.96${\pm}$0.72, p=0.035). N100 amplitude slope of SCZ patients was significantly reduced compared with NC(0.50${\pm}$0.47 vs. 0.96${\pm}$0.72, p=0.027). N100 amplitude slope of BD patients was significantly lower than that of MDD patients(0.54${\pm}$0.70 vs. 0.94${\pm}$0.60, p=0.046). SCZ patients also showed significant reduction of N100 amplitude slope compared with MDD patients(0.50${\pm}$0.47 vs. 0.94${\pm}$0.60, p=0.036). There was no significant difference of N100 amplitude slope between MDD patients and NC(0.94${\pm}$0.60 vs. 0.96${\pm}$0.72, p=1.000). Conclusion : Interestingly, the N100 amplitude slopes of BD and SCZ were reduced compared to NC and MDD patients. Our results suggest the predictive use of N100 amplitude slope in making differential diagnoses of major psychiatric disorders. Clinical implications of N100 amplitude slope in major psychiatric disorders were discussed.
