Objectives : To clarify clinical features of panic disorder and to compare the characteristics of cognitive patterns, avoidance behaviors, and coping strategies among patients who have panic disorder with or without agoraphobia. Methods : Family backgrounds, cognitive patterns in the first panic attack, coping strategies, and avoidance behaviors were compared among the three groups classified by panic patients with mild agoraphobia(mild PDA=66), severe agoraphobia(severe PDA=71), and without agoraphobia(PD=21) Results : 1) Severe PDA reported significantly high panic attack frequency and more dysfunctional level than PD. 2) Catastrophic thinking of 'dying' in PD was significantly frequent than the other groups. Other fears of 'going craze or loss of control' in severe PDA were the highest among the three groups, though it was not significant. Specific thinking process or interpretation in the first panic attack was not significantly different among the three groups. 3) As avoidance behaviors became worse, the frequency of avoidance behaviors and the patters of avoidance behaviors increased. Conclusions : The results suggested that as avoidance behaviors became worse, the frequency of panic, maladaptive functioning and the patterns of avoidance behaviors increase. This might be why we need to decrease avoidance behaviors through exposure as the treatment.

Among the disposal techniques of inorganic wastewater sludges from industries, most of sludges were dealed with buring underground inefficiently. But we have tried to recycle the resources that exhausted inorganic sludges were properly blended to certain ratioes to make lightweight aggregate, that means manufacturing of it can be possible through blending of various components, drying, sintering, cooling and crushing to certain sizes that are needed by consumers. As disposal method of inorganic wastewater sludge is changed to environmentally fraternative method, this method could be very useful to make lightweight aggregates for decoration of building and the other so many purposes of those usages. That could be economically useful due to expected income for buring costs of ordinary disposal method from industries and sales income after manufacturing it. The second important profit is saving foreign currency from purchasing self-developed lightweight aggregate instead of importing expensive foreign product. This product will be also very impressive to user because of the fraternative lightweight to be composed of apatite structure that is important part of human body.

The specific electrical conductivity and the chloride contents were monitored at 98 sits in Cheju Island during two years (1994.2∼1995.11) to the purpose of characterized to regional variations of its elements. The areas of east and west were characterized by both higher elements contain than south and north area. Chloride and specific electrical conductivity values from Kimyoung to Shinhung areas showed more than 100㎎/ℓand 400 μmohs/㎝, respectively. Also west areas relatively high values of both elements were derived from agricultural practice and feeding cattle. However, the difference of difference of these areas indicated that the groundwater environments were different.

권기복,류권일,고영헌,김팔규 忠南大學校 産業技術硏究所 2002 산업기술연구논문집 Vol.17 No.1

Site characterization is one of the most important performances in projects with regard to solving geotechnical problems. Piezocone penetration test is a fast, economic, and accurate method of site characterization. Static cone penetrometer and the piezocone represents the most versatile tools currently available for soil exploration. The cone penetration and piezocone tests provide continuous sounding capability and repeatability. Rare of consolidation parameter may be assessed form the Piezocone test by measuring the dissipation or decay of pore pressure with time after a stop in penetration. And many researches have been developed to determine the horizontal coefficent of consolidation from the Piezocone test. Many of these researches using a theoretical solutions which is determined from either the cavity expantion theory or the stress path method. However, depending on assumptions and analytical techniques, the results can be varied considerably. For that reason, many researchers make their effort to improve and complement the defect of already established methods. In this dissertation, the correlation between the Coefficient of Consolidation from Piezocone dissipation test and the Coefficient of Consolidation Rowe Cell horizontal consolidation test in many cases was studied. The purpose of this study is to know the changing of the Coefficient of Consolidation by loading condition while Rowe Cell horizontal consolidation test is used

술후 진통을 위해 투여한 Ketorolac이 혈액응고 기능에 미치는 영향 : 혈전탄성묘사도를 이용한 평가 A Thromboelastographic Evaluation

최인범,고성훈,김동찬,한영진,최훈,민기철 대한마취과학회 2002 Korean Journal of Anesthesiology Vol.43 No.6

Background: Thromboelastography (TEG) has recently become popular for assessment of whole blood coagulation in the operating room. Ketorolac, a potent injectable nonsteroidal anti-inflammatory drug (NSAID), is commonly used for postoperative analgesia. NSAID inhibit plated aggregation in coagulation process. This study was designed to determine whether ketorolac used for postoperative analgesia can affect hemostatic function using a TEG. Methods: Seventy-four female patients, ASA physical status 1 or 2, scheduled for an elective gynecologic surgery were randomly allocated into one of four groups (Group 1: n=10, control without patient-controlled analgesia (PCA); Group 2: n=21, PCA with morphine 60 mg; Group 3: n=20, PCA with morphine 30 mg + ketorolac 90 mg; Group 4: n=23, PCA with ketorolac 180 mg). Blood samples were obtained for TEG analysis preoperatively and 24, 48 and 72 h after surgery. Cumulative drug dosage, visual analog pain scale, satisfaction degree and side effects were measured at 24, 48 and 72 h after surgery. Results: There were no significant differenced in TGE parameters among the four groups at each time. There were no significant differenced in visual analog pain scales and satisfaction degree among the three groups using PCA for postoperative analgesia. Among the three groups using PCA for postoperative analgesia, Group 2 experienced more side effects. Conclusions: Ketorolac does not affect hemostatic function for 3 days after surgery when administrated as a PCA drug. (Korean J Anesthesiol 2002; 43: 755~762)

본 연구는 폐비닐 펠렛을 도로포장재료로 재활용하여 자원절약 및 아스팔트 혼합물의 품질향상을 위한 연구이다. 이를 위하여 폐비닐의 첨가량별 배합설계를 수행하여 적정 폐비닐 첨가량과 최적 아스팔트 함량으로 편마암과 화강암 2가지 골재와 폐비닐인 RHDPE의 함량을 4가지로 혼합물을 제작하여 8종류의 재질 혼합물과 2종류의 무개질 혼합물을 제작하였다. 그리고 이 공시체에 대하여 마샬안정도, 간접인장강도 및 Kim test와 반복주행시험 등 실내시험을 통하여 혼합물의 특성을 분석하였다. 폐비닐 첨가량은 RHDPE가 8%일 때 안정도와 간접인장강도 모두 가장 우수한 것으로 나타났고 취성도 나타나지 않았다. RHDPE를 첨가한 혼합물에 대하여 Kim test를 수행한 결과 DR과 DS 모두 높은 상관성을 보였다. 그리고 반복주행시험에서는 RHDPE를 첨가한 혼합물이 일반 혼합물보다 우수하였다. 향후 많은 실험을 통해 RHDPE의 우수성을 입증한다면 소성변형 저항성에 우수한 재료로 이용될 수 있을 것이다. This study is a fundamental research for recycled high-density polyethylene (RHDPE) in asphalt mixture for improving roadway pavement. Marshall mix design was conducted and optimum asphalt content(OAC) was determined for dense-graded surface course mixture by RHDPE content. Marshall stability test, indirect tensile strength (ITS) test, wheel tracking trest and Kim-test were carried out to measure the characteristics of RHDPE-added asphalt concretes. From the results of this study, RHDPE in asphalt mixture if possible. It could be considered that adding too much RHDPE in asphalt mixture is not proper. The optimum content of RHDPE was appeared to be 8%. In Kim-test, statistical analysis was performed for each loading head and aggregate to find out correlation between S_(D) values and each rut parameter. The analysis result showed that S_(D) had very high coefficient of determination with rut parameters on the average.

This paper presents a method of suboptimal control for nonlinear systems via block pulse transformation. The adaptive optimal control scheme proposed by J.P. Matuszewski is introduced to minimize the performance index. Nonlinear systems are controlled using the obtained optimal control via block pulse transformation. The proposed method is simple and computationally advantageous. Viablity of the this method is established with simulation results for the van der Pole equation for comparision with other methods.
