Although porous concrete is recently used as a pavement at a parking lot, a public squre and a bicycle road, we use without enough examining. Most the maintenance of quality for porous concrete is only dealt with strength and color tone. Also, there is not et enough fundamental data about dynamical properties for strength, rate of void and water permeability. Even when it is applied to at the scene, it is been a matter. Accordingly in this study analyzed influences through the dynamical properties, combination, and time to vibration. After the analyzation, they investigated peculiar dynamics which are strength of porous concrete, rate of void, and water permeability follow the rate of increase on an admixture making pozzolan reaction. This is purpose to improve capacity of the sidewalk permeable concrete and development of the economical technique for pavement.

Ketorolac (KA) and ketorolac tromethamine (KT) is the nonsteroidal anti-inflammatory drugs (NSAIDs) and has been used widely. To improve its frequent administration by control of drug release. we prepared SLM of KA and KT using Mirj 45 and 52 as surfactants and tripalmitin and tristearin as lipids by spry drying method SLM, as a disperse system for injection, were evaluated by measurement of particle sizes. SEM and drug release pattern As a result. spherical SLM were prepared and their particle size were in the range of 25-125 μm, which were dependant on the types and contents of lipid and sururfactants. Their dissolution rate were decreased as increasing lipid contents.

The purpose of this research is to examine the effect of the aerobic exercise duration on cardiorespiratory function and blood lipids. Total 14 divided into two groups 7, for the control group and the other for the experimental group 7. The subjects of experimental group had 8 weeks aerobic program in the given intensity, during which the changes in cardorespiratory function to body fat and blood lipids were measured three times, at each end of 8th, 8th week. The research is concluded as follows. 1. After 8 Weeks, aerobic exercise brought the decrease of maximum HR with statistically significant(p<.05). 2. After 8 Weeks, aerobic exercise brought the increase of VE with statistically significant(p<.05). 3. After 8 weeks, aerobic exercise reduced TG, LDL-C and T-C with statistically significant(p<.05). In conclusion, aerobic exercise helps overweight women to reduce their weights and the amount of fat and to get rid of elements that cause various geriatric diseases. Therefore, overweight women as well as common adults are advised to take aerobic exercises.

In this paper, field application test of super retarding agent is discussed to reduce hydration heat of mass concrete considering setting time difference of super retarding agent by using horizontal placing layer in Megatrium building construction field at Yongsan in Seoul. Properties of fresh and hardened concrete and hydration heat are investigated, According to test results, both base concrete and flowing concrete meet the requirement of designed slump and air content, although some variances exist. As for compressive strength, it also satisfies the specified strength the consumer need in base concrete and hardened concrete. As for hydration heat, highest temperature of middle section in top placing layer is 65v at 28hours, and in bottom placing layer is 73℃ at 68hours.

한국판 소아 양극성장애 설문지 2.0(Child Bipolar Questionnaire 2.0)의 신뢰도 및 타당도 연구

Objectives : The Child Bipolar Questionnaire 2.0 (CBQ 2.0) is a rapid screener with a Core Index subscale of symptom dimensions frequently reported in childhood-onset bipolar disorder (BD) and scoring algorithms for DSM-Ⅳ BD, with and without ADHD, and the proposed Narrow, Broad, and Core phenotypes. This report provides preliminary data on the reliability and validity of the CBQ 2.0-Korean version. Methods : Core Index subscale to effectively predict diagnostic classification by structured interview was assessed using the Kiddie-Schedule for Affective Disorders and Schizophrenia-Present and Lifetime Version-Korean Version (K-SADS-PL-K). Test-retest and inter-rater reliabilities of the CBQ 2.0 were assessed. Correlation of Korean Child Behavior Checklist (K-CBCL) with CBQ 2.0-Korean version was performed. Results : The CBQ 2.0 screening algorithms performed with a specificity of 66.7% and a sensitivity of 94.7% in classifying subjects with K-SADS-PL-K diagnosis of BD vs. no BD. The Core Index subscale had “good” agreement with K-SADS-PL-K diagnosis (Kappa=0.676) in identifying BD, ADHD-only, and no diagnosis. Conclusion : This preliminary data is from a sample derived from the child and adolescent psychiatric clinics, further validation is needed with community based samples in which childhood-onset BD is rarer and diagnoses more diverse. The CBQ 2.0-Korean version shows potential for rapid and economically feasible identification of possible childhood-onset BD cases as defined by DSM-Ⅳ criteria as well as by alternate disease phenotypes.

소아 상완골 외과 골절 치료후 발생한 운반각 변화 : 운반각의 새로운 방사선적 측방 방법에 대하여 The New Radiologic Carrying Angle Measuring Method

The lateral condyle fracture of humerus in children is the second most common fracture among the elbow fractures. In dealing with this fracture, we have frequently encountered the various complications due to physeal plate and intraarticular involvement. Change of the carrying angle is one of the common complications, but many authors reported different results about the change of carrying angle. Also, it is too difficult to measure the carrying angle during the early stage of the treatment because of cast immobilization, motion limitation of elbow, and wide variations of radiologic carrying angle according to elbow position changes. We performed this study to find the more stable and predictable new radiologic measuring mothod about the carrying angle, and then analysed the factors affecting the changes of carrying angle of the 23 patients of the lateral condyle fractures of the humerus in children who were treated and followed up more than twelve months at the Department of Orthopaedic Surgery, Dong-A University Hospital from May 1990 to April 1993. The results were as follows. 1. Carrying angles by Beals method showed variable values according to the elbow positions, but A-angles by the new measuring method were relatively stable repudless of the elbow positons. 2. Increase of clinical carrying sngle was 3 cases, decrease was 9 cases, and ranges of clinical carrying angle change were from -7 degress to +4 depees. Imease of A-angle was 7 cases, decrease was 4 cases, and ranges of A-angle change were form -10 degrees to +10 degrees. 3. The change of carrying angle showed no correlation with Jacob stage, follow up duratian, metaphyseal height and interval between injury and treatment. But the incidence and the amount of carrying angle change were increased accarding to the inaeaaed age at injury(r=0.62, P$lt;0.01). 4. Tbere were statistical significant correlation(r= -0.65, P$lt;0.01) and regreasion between the change of carrying angle and A-angle: Y -0.99X + 0.56(Y:change of clinical carrying angle, X: A- angle change), (r2=0.42, P$lt;0.01).

A pilon fracture, which is defined as a comminuted intraarticular fracture of distal tibia, involve the articular surface and metaphysis with occasional extension in the diaphysis. The management has been notoriously difficult due to the associated injury, intraarticular fracture, severe communition of distal tibia, joint incongruity and soft tissue trauma. Most authors has reported good results after a surgical treatment by a priociple of AO group treatment. Rescently, Bone et all reports that ROM and outcomes of the severly comminuted or open fractures of the distal intraarticular tibia were very good in using the external fixator. The result of treatment of 22 cases were analysed at the Department of Orthopedic Surgery, Dong-A University hospital from Mar. 1990 to Feb. 1993. The results were as follows; 1. The incidence of pilon fracture is 8.3% of all anlle fracture treated during same period. 2. The most common cause of injury is fall down(63.3%). 3. The most frequent type is type 3 (54.6%).(by Rudei & Allgower) 4. The most common associated injury is compression fracture of spine and calcaneal fracture(4 cases) 5. There are eight cases open Pilon fracture(36.3%) 6. We had treated severe communited fracture and open fracture by using external fixator, we achived good ROM and outcomes. 7. The more accurate reduction, the better clinical result. 8. Complication of the Pilon fracture were traumatic arthritis, non-union, malunion, wound int, etc.
