ISO 9000 Quality System has been proved it's effectiveness in the advanced countries for years. And many companies in the world has been accepting the Quality System resulting in increasing of sales, decreasing of poor quality goods or complaints and elevating sense of quality, etc. Still, however, in the construction industrial fields, there are several problems to solve in the process of accepting the Quality System such as surveys for speciality of constructing site. If government organization in charge of operating the System, Accreditation Body, Certification Body, research institute and certificated construction companies are searching for the improving devices organically, ISO 9000 Quality System will be settled reasonably in the construction industry and become a good system to guarantee the construction quality and working system.

This study was carried out to remove copper ion in case of activated carbon impregnated sulphur(ACS) dose and different pH using activated carbon impregnated sulphur that prepared from activated carbon at sulphur dioxide atmosphere. Removal copper ion concentration was increased as increasing the ACS dose when copper ion concentration was 10 mg/L. Optimum dose of ACS 13.3 g ACS/L and maximum removal efficiency was 93%. The results obtained from adsorption experiment in the condition of ACS optimum dose when the pH was 3, 4, 5 respectively was pH 5 was excellent.

The purpose of this study was to examine the effects of attachment to the mother, mother's parenting style and young children's emotional regulation on relational and overt aggression. The subjects of this study were composed of mothers whose children were 3, 4, and 5 years old and who were attending five public and private kindergartens located in Chungju City and Chungbuk Province. Data were analyzed by Factor analysis, and Pearson's correlation using SPSSWIN 12.0. The test of model was done with analysis of correlation matrix in AMOS 5.0 using a maximum likelihood estimation. The results were as follows: First, it found that boys' insecure attachment and emotional regulation had a direct effect on both their relational aggression and overt aggression, and all boys' secure and insecure attachment, mothers' affectionate and controlled parenting style had a direct effect on their relational and overt aggression. Boys' secure attachment appeared to have a direct effect on mothers' affectionate and controlled parenting style, while insecure attachment appeared to have a mediating effect on only mothers' controlled parenting style. Second, it suggested that girls' insecure attachment and emotional regulation had a direct effect on both their relational and overt aggression as for boys and all of girls' secure and insecure attachment, mothers' controlled parenting style had a direct effect on their emotional regulation, while girls' secure attachment had a mediating effect on only mothers' affectionate parenting style, and girls' insecure attachment had a mediating effect on only mothers' controlled parenting style. Third, it showed that mother's parenting style had a indirect effect on young children' emotional regulation and aggression through the medium of their attachment. Both mother's affectionate parenting style and their controlled parenting style appeared to influence boys' aggression through emotional regulation, while only mother's controlled parenting style appeared to have a indirect effect on girls' aggression through emotional regulation. Both boys' emotional regulation and girls' emotional regulation appeared to have both a direct and indirect effect on their respective aggression. Fourth, study results indicated that the relative influence that mother's parenting style and young children's emotional regulation had on relational and overt aggression differed according to gender. While boys' insecure attachment appeared to have significant effect on their relational and overt aggression, girls' insecure attachment appeared to have the great effect on their relational aggression and their emotional regulation appeared to strongly influence overt aggression. 본 연구는 문헌고찰을 통해 세워진 이론적 모델을 통해 유아의 애착이 어머니의 양육방식과 유아의 정서조절능력을 매개로 유아의 공격성에 어떠한 영향을 미치는지를 알아봄으로써, 그 결과를 유아의 공격성에 대한 조기 개입의 방안으로 탐색해 보고 부모교육이나 유아교육 및 상담현장에 필요한 기초자료를 제시하는데 목적이 있다. 본 연구의 대상은 청주시와 진천군 소재의 사립유치원과 어린이집 5곳에 다니는 만 3~5세 유아를 가진 어머니를 대상으로 하였다. 본 연구를 통하여 밝혀진 결과를 요약하면 다음과 같다. 첫째, 불안정애착과 정서조절능력이 유아의 공격성에 중요한 영향을 미치는 것으로 나타났다. 둘째, 유아의 정서조절능력에 영향을 미치는 어머니의 양육방식은 남아와 여아간의 차이가 있다. 셋째, 어머니의 양육방식에 영향을 미치는 요인을 살펴보면 남아는 안정애착이 온정적 양육방식과 통제적 양육방식에 직접적인 영향을 미치는 것으로 나타났고, 불안정애착은 온정적 양육방식에 영향을 미치지 않고 통제적 양육방식에 직접적인 영향을 미치는 것으로 나타났다. 여아는 안정애착이 통제적 양육방식에 영향을 미치지 않고 온정적 양육방식에만 영향을 미치는 것으로 나타났다. 반면 불안정애착은 남아와 여아 모두 온정적 양육방식에 영향을 미치지 않고 통제적 양육방식에만 영향을 미치는 것으로 나타났다. 넷째, 본 연구에서 가장 주목할 만한 결과는 남아와 여아 모두 유아의 정서조절능력이 대인관계 공격성과 외현화 공격성을 경감시키는 가장 중요한 변수로 나타났다는 것이다.

Acinetobacter species is a non-fermentative aerobic gram-negative coccobacillus that is an important pathogen found in nosocomial infections. Recently, multi-drug resistant Acinetobacter baumannii (MDR-AB) infections have been increasing and pose a serious problem. Most such infections present as bacteremia, pneumonia, or a wound infection; however, CNS infections are very rare. We herein present a case of ventriculitis caused by MDR-AB in a 37-year old man after a neurosurgical intervention. The patient was successfully treated with intrathecal colistimethate.

Upper gastrointestinal bleeding is common and potentially life threatening medical emergency. Emergency endoscopy is the first choice of diagnostic and treatment measure for patients with active upper gastrointestinal bleeding. Histoacryl should be considered a second-line treatment modality when conventional treatments were failed. However, it might cause several complications. Herein, we report a case of acute pancreatitis developed after histoacryl injection therapy for active duodenal ulcer bleeding. A 71-year-old man was admitted with melena and hematemesis. On emergency endoscopy, a 2 cm sized active ulcer with bleeding from an exposedvessel was seen at the duodenal bulb. Attempts to arrest the bleeding with hemoclipping and submucosal epinephrine injection were tried, but failed. We changed the method to endoscopic histoacryl injection, and obtained hemostasis immediately. A few hourslater, after successful hemostasis, patient complained diffuse abdominal pain. Ultrasonography revealed hyperechoic heterogenous diffuse pancreatic enlargement and right pararenal space fluid collection, this ultrasonographic findings and elevated serum pancreatic enzymes are compatible with acute pancreatitis.

액정 8OCB(octyloxycyanobiphenyl)에 액정 5OCB(pentyloxycyanobiphenyl)를 무게비로 혼합하여 혼합액정 (8OCB+5OCB)을 만들었다. 이 혼합액정은 5OCB의 무게비에 따라 McMillan지수 (??)가 감소하였다. 그리고 Rayleigh 광산란 실험방법을 이용하여, 순수 8OCB와 혼합액정의 네마틱-스멕틱 A 상전이 근처의 네마틱상에서 산란된 빛의 세기를 온도와 함수로 측정하였다. 실험데이타 분석결과는 휨(bend) 탄성 상수에 비례하는 세로방향 상관거리(??)는 McMillan 지수에 관계없이 임계지수 ??=0.66±0.03을 갖고 발산하였다. 이 값은 de Gennes의 모델에서 제시된 ??=0.67과 일치함을 알수있다. By utilizing Rayleigh scattering technique, we have measured the temperature dependence of scattered light intensity near nematic to smectic-A phase transition point in the pure 8OCB(octyloxycyanobiphenyl) and its mixtures contaning 5, 10, 15 weight percentage of 5OCB(pentyloxycyanobiphenyl). From analysis of these data. it is found that the longitudinal correlation length (??) diverges with critical exponent ??=0.66±0.03 independent on McMillan parameter (??). This result is consistent with de Gennes model (??).
