The purpose of this study was to examine the displacement of glenoid fossa during growth, and to investigate the relationship between the displacement of glenoid fossa and mandible. Pretreatment and posttreatment lateral cephalograms of 41 patients (male : 13, female : 28) were obtained from the orthodontic clinics of WonKwang university hospital and were analized in terms of the position of articulare and mandible and statistically. The obtained results were as follows ; 1. Articulare was displaced posteriorly and inferiorly during craniofacial growth and development. 2. The more posteriorly articulare displaced, the less anteriorly pogonion displaced, but the more inferiorly menton displaced. 3. The more posteriorly or inferiorly articulare was located, the more inferiorly menton displaced, and the more posteriorly articulare was located posteriorly, the less cant of the mandibular plane.

To evaluate the clinical efficacy of ciprofloxacin (CFX) on treatment of the pigs with respiratory diseases or diarrhea. CFX at various dosages were administered intramuscularly to the diseased pigs selected from the pig farms located in Chungnam province. One hundreds and fourteen heads of pigs with respiratory diseases were divided into five groups and CFX at 0.25, 0.5, 1.0 (= 2.5mg CFX/Kg B.W.) and 2.0 doses were administered i.m. for 5 days. The recovery rates were found 31.8%, 73.9%, 91.3% and 92.0%, respectively, being higher than that of the untreated control group (19.0%). The mortality of the treated groups were 0%, that is lower than that of the control (9.5%). Seven kinds of bacteria were isolated from the respiratory organs of 86 pigs, and 34 (39.5%) of 86 pigs showed the complicated infection. In analyzing by the pigs infected with a single pathogen as P. multocida; A. pleuropneumonia. Staphyloccus spp. or Mymplasma spp., the recovery rates were 0∼66.6% at 0.25 dose, 66.6∼100% at 0.5 dose and 100% in all of 4 pathogens at 1.0 to 2.0 doses. At 0.25 dosage the pigs infected with A. pleuropneumonia showed the lowest recovery rate. One hundreds and twenty two heads of pigs with diarrhea were divided into five groups and CFX at 0.25, 0.5, 1.0 (= 2.5mg CFX/Kg B.W.) and 2.0 doses were administered i.m. for 5 days. The recovery rates were 29.1 %, 40.0%, 80.0% and 88.0%, respectively. The mortality of the treated groups were 0∼8.3%, being much lower than that of the control. Four kinds of bacteria were isolated from the fecal specimens of 94 pigs, and 84 (89.0%) of 94 pigs showed the complicated infection.

The purpose of this study was to evaluate the changes of skeletodental factors in Class Ⅱ, division 1 malocclusion, following treatment with or without the extraction of four first premolars. one hundred and one treated cases were devided into four groups by sex and treatment type. Various skeletodental and facial factors in pre and post-treatment lateral cephalograms and study models were measured and compared by Students' t-test. The results were as follows; 1. There was a facial height reduction in extraction group. 2. Extraction treatment was more effective in retraction of upper incisors and lips. 3. Lower incisors were titled lingually in extraction group, but labially in nonextraction group. 4. Maxillary space deficiency was resolved by lateral maxillary expansion in nonextraction group.

This paper suggests modified sliding mode control that is not only stability and is great in control on elastic structure but also effect of structural response reduction. Proposed algorithm can use saturated controller's capacity as occur short control force which is needed the ratio of target derivation. Simulation results using performance evaluation criteria indicate that modified SMC method is effective in reduction of displacement and acceleration.

Acupuncture is used to treat pathological conditions and to prevent pain from arising. The pathological conditions that can be treated can be painless or painful conditions. Acupuncture analgesia (AA) is a specific form of acupuncture; the stimulation of the acupuncture points must be strong and long (about 15 to 30 minutes) before a local or general analgesia or hypalgesia will develop. Development of modern AA began in the late fifties. Effectiveness of acupuncture in alleviation of pain was quickly noticed and brought to the medical researchers and surgeons. Through their diligent pursuit, AA has been established as a viable alternative for relief of pain and substitution of conventional anesthesia. In veterinary medicine. early successful applications of AA to surgery of domestic animals were reported in the late sixties. Local or regional anesthesia is often preferred to general anesthesia in cattle. Acupuncture was effective in inducing analgesia. Regional electroacupuncture analgesia is potentially useful for standing surgeries in cattle. Some standing surgeries may be easily accomplished using electroacupuncture anesthesia.

This study aims at revealing the physiological responses of dehydration (DH) and rehydration (RH) in intermittent exercises at the work intensity of 70% HR max. First, with general student public, three times of exercise (each for 20 minutes) at the given work intensity were taken, with a break for 25 minutes respectively. Their heart rate, rectal temperature and plasma electrolyte concentration both DH and RH were measured. Second, in two groups of athletes and non-athletes, 9 rounds of exercise (for 100 minutes) and 8 breaks (for 60 minutes) were taken, with RH forced 10 times to compensate for the subjects' water loss. Their change in sweat loss and plasma electrolyte concentration as well as the IVDP(Intensive Voluntary dehydration Phenomenon) were experimented. The summary of this research follows. 1) Mean heart rate and rectal temperature in intermittent exercises were higher at DH than at RH, growing up at the increasing level of DH. 2) RH saw no change in the plasma concentration of Na+, K+ and Cl-, while DH observed a significant increase. 3) HCO₃made a significant decrease at DH before growing up. 4) Mg++ had no change, while Ca++ increased significantly at RH and DH. 5) Lactate showed an increase with significance at RH and DH, especially greater at DH. 6) Osmotic pressure increased meaningfully at DH. 7) Anion gap increased significantly at DH and RH. 8) On the other hand, when the forced RH was held, the group of athletes had greater sweat loss per body surface area than that of non-athletes. 9) The athletes' plasma concentration of Na+ and Cl- revealed a clear decrease. 10) There was seen no significant change in the plasma concentration of K+, Mg++ and Ca++ in both groups. 11) The IVDP occurred at the RH of 2.3ℓfor athletes and more than 2.5ℓfor no-athletes.

열린 과학 교육의 필요성에 대해서는 많은 사람들이 공감하고 있다. 그러나 아직 열린 과학교육에 대한 구체적인 정의와 지도 방법이 마련되어 있지 않다(Choi,K.H., 1994). 본 연구에서는 열린 과학 교육을 위한 연수 자료를 개발하고 전국 초, 중, 고 연수 담당자 및 과학 전문직을 대상으로 열린 과학 교육 연수를 실시하였다. 연수 후 열린 과학 교육의 문제점과 지도 방법에 대한 의견을 수렴하였다. 충분한 토의와 협의를 통해 학교 현장에서 실시할 수 있는 열린 과학 교육 방안을 마련하였다. 연수에 참여한 모든 과학 교육 담당자는 열린 과학 교육에 대한 의견을 제시하였다. 본 연구에서는 설문 결과를 바탕으로 열린 과학 교육에 대한 바람직한 방안을 마련하였다. 현재의 학교 환경을 고려하여 4가지 형태의 열린 과학 교육 방법을 제시하였다. 열린 과학 학습 형태 1은 예측, 실험 수행, 결과 토의 등의 단계를 거치는 직소형 학습 방법이다. 열린 과학 학습 형태 2는 학습자의 특성에 따라 교사의 지도 방법이 달라지는 학습 방법이다. 열린 과학 학습 형태 3은 탐구 단계별로 학습하는 학습 방법이다. 열린 과학 학습 형태 4는 학습자 스스로 자신의 학습 수준을 파악하고 수준에 맞는 학습 방법대로 학습하는 방법이다. Many peoples recognize the need of open science education by students' cognitive level. But identification and teaching method of open science education by students' cognitive level are not prepared. We developed teachers' training program for open science education by students' cognitive level and trained science teachers' trainers and inspectors. After the training program was completed the problem and the direction of open science education by students' cognitive level were presented. By this workshop's results we suggest the desirable plan of open science education by students' cognitive level.
