Simultaneous treatment of phenol, m-cresol and formaldehyde in wastewater was carried out in a fluidized bed reactor. The response of the treatment unit against the change of inlet pollutants concentration was measured by changing stepwise the concentration of one component in the mixture. The mutual interaction between each components was quite different. Simultaneous biodegradation of phenolic compounds and formaldehyde could be successfully and stably carried out in a three phase fluidized bed by taking enough residence time.

2-Arch 터널의 막장면 종방향 적정 이격거리에 관한 연구

이민규,정지수,이성기,이승호,Lee, Min-Kyu,Jeong, Ji-Su,Lee, Sung-Ki,Lee, Seung-Ho 한국터널지하공간학회 2007 한국터널지하공간학회논문집 Vol.9 No.4

최근 선형분리 곤란, 환경훼손 최소화 및 용지보상 등의 이유로 2-Arch 터널의 채택이 점점 증가하고 있다. 이런 실정에도 불구하고 2-Arch 터널은 국내에서의 시공실적 및 설계사례의 부족으로 자료의 데이터화가 체계적이지 않고 2-Arch 터널의 역학적인 거동 메커니즘에 대한 연구가 미흡한 실정이다. 따라서 본 연구에서는 2-Arch 터널의 종방향 이격거리에 대한 연구를 통해 본선 선행터널과 중앙벽체의 거동 메커니즘을 분석하고 적정 이격거리를 제안하고자 한다. 2-Arch 터널의 이격거리 산정은 터널의 안정이 확보되는 조건에서 산정하는 것이 타당하며, 이격거리에 따라 보다 민감하게 작용하는 중앙 벽체의 거동에 영향을 최소화 할 수 있는 범위내에서 이격거리를 산정하는 것이 바람직할 것으로 판단된다. 또한 이격거리에 따른 중앙벽체의 민감도 분석결과 최대 변곡점이 생겨 급격한 응력변화가 발생하는 0.5D이내를 이격거리로 산정하는 것이 타당할 것으로 사료된다. Recently, due to the effective land utilization and environmental protection, the construction of 2-arch tunnel has been gradually increased. In spite of this tendency, the mechanical information for the 2-arch tunnel, especially such as its behavior characteristics and mechanism are not enough. Therefore in this study, the theoretical and numerical studies on the behavior characteristics of 2-arch tunnel are carried out and longitudinal optimum separated distance of tunnel face is proposed by considering the analysis results from the behavior of advanced excavation of tunnel and stress of central pillar. As a result, longitudinal optimum separated distance of tunnel face is in 0.5D for the better safety of 2-arch tunnel by rapidly decreasing the stress concentration of central pillar.

이민규,고영택,이혜경,황을지,이영호,Rhee, Min-Kyu,Go, Young-Taek,Lee, Hye-Kyung,Whang, Eul-Ji,Lee, Young-Ho 한국정신신체의학회 2001 정신신체의학 Vol.9 No.2

본 연구는 KEAT-26의 변별 타당도를 알아보고 이 척도의 진단적(분류적) 효율성을 알아보기 위해서 이루어졌다. 참여자는 여성 식사장애 환자 108명, 체형관리센터에서 체형관리프로그램에 참여하고 있는 여성 179명, 체대운동여학생 120명, 일반여자대학생 227명 그리고 일반여자 183명(총 817명)이었다. 변량분석과 ROC(Receiver Operating Characteristic Curve) 곡선 분석을 통해서 이 척도의 타당화를 시도하였다. 그 결과 KEAT-26 총점수가 집단간에 통계적으로 유의한 차이를 보였으며, 사후 검증에서 식사장애 환자집단이 다른 모든 집단보다 KEAT-26 점수가 유의하게 높았다. 그리고 각 집단에 따른 KEAT-26의 4 개 하위 요인점수의 차이 검증에서 모든 하위요인들에서 집단의 주 효과가 유의하였으나, 사후검증에서 요인 IV의 변별력이 떨어졌다. ROC 곡선 분석을 통하여 이 척도의 분류적인 효용성과 최대의 가질 때의 절단접수를 알아본 결과 식사장애 환자와 정상인 집단을 분류할 때 평균 약 80%이상의 효용성이 있으나 식사장애 고위험 집단을 변별할 때는 평균 약 69%의 효용성을 보였다. 특히, 최고의 효용성을 보일 때의 절단점수를 효면, 식사장애환자와 체형관리자를 분류할 때 절단점이 25점, 식사장애환자와 일반 여자를 분류할 때 분류점수는 19 점, 삭사장애환자 대 체대운동여학생의 분류 점수는 23점, 식사장애환자 대 일반여대생의 절단점은 21점이었다. 이민규 등(1998)이 제안한 T점수 65에 해당하는 KEAT-26의 총점 22점을 절단점수로 했을 때 이 척도의 민감도 54%, 특이도 84%, 효율성은 평균 80% 이었다. 본 연구 결과 KEAT-26온 한국 사람이 겪고 있는 식사문제에 관련된 연구에 필요한 신뢰롭고 타당한 도구임을 밝혀졌다. 또한 본 연구결과는 이 척도가 임상적인 이용 뿐 만 아니라 역학조사 동의 목적으로 식사문제가 있는 사람을 선별하는데도 유용한 도구임을 지지해 준다.

The combination of Congenital central hypoventilation syndrome with Hirschsprung's disease, also known as Haddad syndrome, belongs to the family of diseases now designated as Neurocristopathies. We have experienced a case of Haddad syndrome in a male infant who presented with repetitive abdominal distension, bilious vomiting, and sleep apnea. Following colon study and rectal biopsy disclosed the absence of the ganglion cell. And the infant could not be weaned from mechanical ventilation since birth because of the absence of effective, spontaneous respiration during sleep. As he was diagnosed as Haddad syndrome, tracheostomy and ileostomy were performed consecutively. At the age of 4 months, he was relatively healthy but remained ventilator-dependent. We report the first Korean case of Haddad syndrome with a brief review of the related literature.

Zeolites could be easily synthesized from scoria, that is abundantly found in the Cheju island. The synthetic zeolite showed more better adsorption ability about the heavy metal ion than that of raw scoria, The results of the adsorption experiment about Analcime(ANA) suggested the highest value and the removal amount of Pb²+ was 40mg Pb/g at this time. The selectivity of ANA about metal ions was decreased with next orders; P²+ $gt; Cu^(+2) $gt; Zn^(+2).

The purpose of this study was to test a reliability and validity of the Korean version of Eating Attitudes Test-26(KEAT-26). Using multi-stage sampling, we finally got 3,496 subjects(1422 males and 2074 females) who were available for analysis from target 4,400 Korean adults over 18 in the nationwide areas of9 kus, 10 middle or small cities, and 17 kuns. We tried to make T score norm of the KEAT-26 as a cutoff score and STEN score norm as a index of severity for disordered eating behaviors. For the male group, Cronhach's internal consistency was .83 and Spearman-Brown split half correlation coefficiency was .75. For the female group, each of them was .81 and .75, and .81, .75 for the grand total group respectively. Validity test was performed by construct validation analysis. By a iterated principal axis factoring, 4 factors were extracted. There were some differences in the factors of the KEAT-26 by sex. In the male group, factor I was 'self-control of eating and bulimic symptom', factor II was 'food preoccupation and dieting', factor III was 'preoccupation with being thinner', factor N was 'avoidance of sweet foods'. In contrast with the male group, factor I was 'self-control of eating and bulimic symptom', factor II was 'preoccupation with being thinner', factor III was 'food preoccupation' and factor N was 'dieting' in the female group. We used T score 65 as a cutoff score. T score 65 corresponded to raw score 19 in the male group, 22 in the female group and 21 in the grand total group. Severity of disordered eating behaviors was measured by a STEN score. In the male group, each of the score range of 0-10, 11-14, 15-18, 19-22 and over 23 represented the degree of none, subclinical, manifest, moderate and severe severity respectively. Each of the score range of 0-13, 14-17, 18-21, 22-26 and over 27 in the female group, and the score range of 0-12, 13-16, 17-20, 21-25 and over 26 in the grand total group also represented the same degree of severity as like in the male group. These results support that KEAT-26 is a reliable and valid scale for evaluating disordered eating behaviors and eating problems.

어뢰대항전술 영향을 고려한 수상함의 대잠탐색패턴 연구

The tactical effectiveness, which is the result of applying decision-making algorithms to respond a specific situation with weapons and sensors, is required to analyze according to the integrated combat situation, because each situation, which is intimately involved with each other, influences the surface ship to complete missions successfully. However, the tactical effectiveness have been analyzed in separation of each tactical situation due to the complexity of the integrated tactical situation. This paper is originated from the needs for analyzing the anti-submarine search region of the surface ship after it evades the torpedo by operation of the torpedo countermeasure tactics. It also describes simulation results of effectiveness analysis for the search patterns in the search region.

It is necessary for us to undergo trial and error for eliciting the rational requirement of the acquisition of weapon systems, but the M&S is general approach due to costs and risk of the development. In addition to the acquisition of weapon systems, M&S is extensively employed in the analysis and the training of developed weapon systems. The ADD (Agency for Defense Development) has developed DEVS integrated development environment (QUEST) that provides M&S general ground technique composed of simulation model implementation services, simulation result analysis services, and simulation interface services. This paper describes the interface architecture and the implementation of torpedo target detection section interface simulation system using QUEST. The torpedo target detection section interface simulation system is composed of torpedo target detection section which calculates a result of target detection and the QUEST scenario generator which provides simulation scenario for performance test of the torpedo target detection section. The interface architecture of torpedo target detection section interface simulation system is designed to verify the interface and performance of the torpedo target detection section by linking with the QUEST scenario generator.
