The purpose of this study was to examine the effects of pelvis corrective exercise for low back pain sampled from high school baseball players who complained their low back pain. Lumbar shape, and pain responses were examined before and after treatment to identify the effects of pelvis corrective exercises. The number of subjects were 39 consisted of four groups: control group, active goroup, assistive group, and active/assistive combined group. The time periods of treatments were 30 minutes per day, 5 times a week, total 18 weeks. Lumbar X-ray, DITI(Digital Infrared Thermographic Imaging) were utilized before and after treatment for data collection. Kruskal-Wallis Analysis was used to compare the differences of lumbar shapes as well as the differences of pain responses in between groups. The results of this study were as follow: 1. The effects on lumbar sacral angle among tests of lumbar shape were found most forcefully in assistive group and active/assistive combined group next. 2. The effects on pain responses were shown in rank such as active/assistive combined group first, assistive group second, and active group third. Therefore, pelvis corrective exercises could be regarded as an effective method to correct body type and relieve low back pain.

As an institution of higher education, universities play an important role in the future development of a country in education and research. Universities have long been called ivory towers, but today there is a controversy over whether to respond appropriately to the supply of educational services compared to social expectations and demand. On the other hand, as it has been subject to evaluation by various institutions, universities are investing a lot of manpower and time to prepare for evaluation prior to carrying out their essential functions of education, research, and volunteer activities. One of the most important evaluations is the evaluation system being conducted by the government. The government is also exposed to an unavoidable environment. Representatively, the rapid environmental change surrounding the university due to the possibility of devastation of higher education institutions due to the rapid decline of the school-age population increases the difficulty of policy establishment and execution by the policy authorities, and it can be said to be a more confusing situation from the university standpoint. However, regardless of any difficulties, universities will have to perform their own functions. For this, necessary resources must be secured, and an efficient operation system and performance management system must be established. The government's university evaluation seems to be focusing on this area. This study first attempts to grasp the characteristics of the Ministry of Education's university evaluation system three times until recently. From the standpoint of the manager in charge of the management of the university, I would like to find a way for the university to fulfill its original function and to be free from evaluation.

세계적 대학평가 체계들이 정부의 대학평가 정책 및 대학 대응에 주는 시사점

박준훈,정기만 한국교통대학교 2021 한국교통대학교 논문집 Vol.56 No.-

The purpose of this study is to briefly examine the characteristics and indicators of the global university evaluation systems and to find out what implications they have for the government-related departments that establish education policies and our universities. The retention rate index, which had the largest weight in the USN&WR, a representative evaluation system in the United States, which Korea is generally interested in and is relatively influenced by, has great implications. This is because the United States is not free from the aspect of the school-age population or the university-going population. In the case of Korea, since the population change is more dramatic, it cannot be overemphasized how much the future retention rate and the fill rate, which is the basis for this, can be overemphasized. Let's look at the evaluation indicators of the 3rd cycle university basic competency diagnostic evaluation. Overall, about half are pure metric indicators, and there may be various opinions about the indicators themselves and their weights in this part, but there is no fundamental dispute.

이종접합재 접합 계면근방 균열의 응력 및 파괴특성

현재까지 이종마찰압접재의 강도측정은 실험 (7)-(15)에 의해 구해져 왔다. 하지만 최근 이종마찰압접재의 효율성을 인정하여 여러 실용 부품에 응용하려는 연구가 한창 진행중이다. 이종마찰압접재에 대한 저자들(1)-(6)의 기초실험결과 일반적인 단종재와는 상이한 파괴거동(3)이 관찰되었고, 파괴역학적인 관점에서 정성적인 data 확보가 필요하게 되었다. 따라서 본 연구에서는 인장시험시 이종마찰압접재의 접합강도와 미소균열들에 의한 파괴거동을 파괴역학적 관점에서 해석적으로 고찰하여 보고자 경계요소법(BEM ; Boundary Element Method)을 이용하여 접합계면을 포함하는 접합부를 중심으로 계면상의 응력분포와 계면의 중앙에 결함이 균열로써 존재하는 경우의 응력분포와 인장시험시 열영향부에서 관찰된 균열의 모델링을 통한 균열선단에서의 응력해석을 행하였고, 그 결과 얻어진 중요한 내용을 요약하면 다음과 같다. 계면의 중앙에 균열이 존재하는 접합계면의 표면부에서 응력의 특이성이 발생하며 탄성계수의 비가 증가할수록 특이성이 증가함이 관찰되었다. 탄성계수의 비가 일정한 경우 균열의 크기가 변화하여도 계면의 표면부에서 발생하는 특이성은 거의 같은 값을 갖게 되며, 탄성계수의 비가 증가할수록 표면부의 응력 특이성의 크기는 증가한다. 이종마찰압접재의 인장시험시 관찰된 균열을 모델링 하여 해석한 결과 최대 응력 기준으로 살펴볼 때 인접한 균열선단에서의 응력분포는 균열을 합체시키는 방향으로 작용함을 알 수 있다. In this study stress distribution on the interface and stress near tip of the sub-interface crack in the dissimilar friction welded material is analyzed by using of BEM( Boundary Element Method). Stress singularity near surface of model to analyze is observed for various crack length and ratio of elastic modulus. Tensile and shear stress distribution near two neithbor sub-interface crack tips are analyzed. Existance of singularity near surface on the interface is particular situation so that we need to investigate for dissimilar friction welded materials by means of numerical analysis method.

In the evaluation of the result of reduction of fractured nasal bone, 'the degree of satisfaction of the patient' is the most important factor. There were several reports regarding 'patient's satisfaction'. However they are not related to individual factors such as age, sex, cause of injury, method of reduction, etc but are the 'overall' rate of satisfied patients. We tried to know what should we do in the individual steps in treating fractured nose to reduce the rate of dissatisfaction. We analysed 120 consecutive patients who underwent reduction in Inje University Sanggye Paik Hospital due to fractured nose from August of 1989 to March of 1993. The results were as followings ; 1) There were many dissatisfied cases in second and third decades(p=0.054). 2) In case of severe combined injury requiring general anesthesia, the rate of dissatisfaction was high(p=0.061). 3) In cases with septal fracture, the rate of dissatisfaction was high(p=0.042). 4) The operation should be performed before 24 hours after trauma or on the fifth, sixth, and seventh posttraumatic day because the rate of dissatisfaction was low(p=0.023) 5) To evaluate the effect of splinting, further study is necessary. We should follow-up for longer time and it is difficult to define criteria of satisfaction of individual persons. We think that further research can clerify the protocol in the treatment of nasal bone fractures.

SMA 혼합물의 피로저항성 개선방안 연구

국내의 SMA 혼합물 생산시 대부분 일반 아스팔트와 셀룰로오스 섬유만을 사용하여 왔으나, SMA 혼합물의 공용성을 극대화시키기 위해서는 일반 아스팔트 대신 개질 아스팔트를 사용하는 것이 필요한 것으로 판단된다. 본 연구에서는 SMA 혼합물에서 일반 아스팔트 바인더 대신 개질 아스팔트를 사용한 SMA 혼합물에 대한 실내실험을 실시하여 SBS 개질 SMA 혼합물의 실내 공용성을 평가하였다. 실내시험결과 개질 SMA 혼합물의 피로수명이 일반혼합물에 비해 약 10배 이상 증가하였으며, 휠트래킹 시험을 통한 소성변형 저항성은 개질 SMA 혼합물이 일반 혼합물에 비해 약 3배정도 큰 것으로 나타났다. 또한 접착인장강도는 개질 혼합물이 일반 혼합물에 비해 21∼48% 높게 나타났으며, 저온휨시험 역시 개질 혼합물이 일반 혼합물에 비해 22∼38% 높게 나타났다. 수분손상시험에서는 개질 혼합물은 모두 기준에 만족한 반면, 일반 혼합물은 모두 기준을 만족하지 못한 결과를 나타내었다. 따라서 전체적으로 일반 아스팔트 혼합물에 비해 SBS 개질 SMA 아스팔트 혼합물의 실내 공용성이 뛰어난 것으로 평가되었다. In general, SMA mixes in Korea use unmodified asphalt binder and cellulose fiber. To increase the performance of the SMA mixes, it seems to be necessary to use modified asphalt binders. In this study, the laboratory performance of SBS modified SMA mixes instead of using conventional unmodified asphalt binder was evaluated. Uniaxial tensile fatigue test results revealed that the SBS modified SMA mixes had almost ten times longer fatigue lives than the conventional SMA mixes. Wheel tracking test, which was conducted to evaluate the rutting resistance of mixes, showed that the dynamic stability values of the modified SMA mixes were three times higher than the values of the conventional SMA mixes. In addition, both adhesive tensile strength and low temperature bending strength values of the modified SMA mixes were higher than the values of the conventional SMA mixes by 21∼48% and 22∼38%, respectively. According to the moisture damage tests, the modified SMA mixes satisfied the mix design criteria while the conventional SMA mixes did not stisfy the criteria. Overall, the SBS modified SMA mixes showed better laboratory performance than the conventional SMA mixes.

연구목적 : 본 시험의 목적은 임상시험 시작전에 연구자들을 대상으로 PANSS Workshop을 통하여 PANSS, ESRS에 대한 국내에서의 표준화 작업을 구축하고 새로운 정신병 치료제인 리스페리돈의 효과와 안정성을 재확인하여 리스페리돈 사용에 대한 적정화를 이루는데 있다. 연구방법 : 1996년 4월부터 1996년 9월까지 국내 39개 대학병원 정신과에 입원중인 혹은 증상이 악화되어 입원하는 정신분열병 환자 377명을 대상으로 다시설 개방 연구를 시행하였다. 1주일간의 약물 배설기간을 가진후, 리스페리돈을 8주간 투여하였고, 기준점, 1주, 2주, 4주, 그리고 8주후에 평가되었다. 용량은 제1일에는 리스페리돈 1mg씩 1일 2회, 제2일에는 2mg씩 1일 2회, 제3∼7일에는 3mg씩 1일 2회 투여하였다. 이후 환자의 임상상태에 따라 임의로 증량할 수 있으며, 최대 일일 16mg을 초과하지 않도록 하였다. 추체외로 증상을 조절하기 위한 투약을 허용하였다. 임상증상 및 부작용의 평가는 PANSS(Positive and Negative Syndrome Scale), CGI(Clinical Global Impression) 그리고 ESRS(Extrapyramidal Symptom Rating Scale)을 사용하였다. 연구결과 : 377명중 343명(91%)이 8주간의 연구를 완결하였다. 치료 종결시점인 8주후 PANSS 총점수가 20% 이상 호전된 경우를 약물 반응군으로 정의할때, 약물반응군은 81.3%였다. 리스페리돈에 반응하는 예측인자로는 발병연령, 이전의 입원 횟수, 유병기간이 관련 있었다. 리스페리돈은 1주후부터 PANSS양성, 음성, 및 일반정신병리 점수상에 유의한 호전을 보여 효과가 빨랐다. CGI의 경우도 기준점에 비해 1주후부터 유의한 감소를 나타내었다. ESRS의 경우, 파킨슨 평가점수는 기준점과 비교해 투여 1주, 2주, 4주후 유의하게 증가되었다가 8주후 기준점과 차이가 없었다. Dystonia 평가점수는 1주후만 유의한 증가를 보였으며, dyskinesia 평가점수는 유의한 차이가 없었다. 혈압, 맥박수의 생명징후 및 일반 혈액학 검사, 생화학적 검사, 심전도 검사에서 유의한 변화는 없었다. 결 론 : 이상의 다시설 개방 임상 연구를 통해 리스페리돈은 정신분열병 환자에서 양성증상뿐만 아니라 음성증상 및 전반적인 증상에도 효과적인 것으로 사료된다. 보다 명확한 평가를 위해서는 다른 항정신병약물과의 이중맹검 연구가 필요할 것으로 생각되며, 또한 장기적 치료에 대한 평가도 함께 이루어져야 하겠다. Objective : The purpose of this study was to investigate the efficacy and safety of risperidone in the treatment of Korean schizophrenic patients. Method : This multicenter open study included 377 schizophrenic patients drawn from 39 university hospitals. After a wash-out period of 1 week, the schizophrenic patients were treated with risperidone for 8 weeks and evaluated at 5 points ; at baseline, and 1, 2, 4 and 8 weeks of treatment. The dose was increased from 2mg/day(1mg twice daily) to 6mg/day(3mg twice daily) during the first week and adjusted to a maximum of 16mg/day over the next 7 weeks according to the patient's clinical response. Medication to control extrapyramidal symptoms was permitted. The psychiatric and neurological status of the patients was assessed by PANSS, CGI, and ESRS scales. Results : 343(91%) of 377 patients completed the 8-week trial period. Clinical improvement, as defined by a 20% or more reduction in total PANSS score at end point, was shown by 81.3% of patients. The predictors of response to risperidone were associated older age, shorter duration of illness, fewer previous hospitalization. Risperidone had rapid onset of action ; a significant decrease of the total PANSS and three PANSS factor(positive, negative, general), and CGI was already noticed at the end of first week. For the ESRS, parkinsonism rating scores were significantly increased until week 4 comparing with baseline. Dystonia rating scores were significantly increased until week 1, and dyskinesia rating scores were not significantly changed during the study. Laboratory parameters including vital sign, EKG, hematological, and biochemical values showed no significant changes during the trial. Conclusions : This study suggests that risperidone is generally safe and effective against both the positive and negative symptoms in our group of patients.

목적: 압박고 나사를 이용한 전자간 골절의 수술적 치료 후 발생할 수 있는 고정실패에 영향을 줄 수 있는 인자들을 분석하고자 한다. 대상 및 방법: 1996년 2월부터 2001년 2월까지 본원 정형외과에서 압박고 나사를 이용하여 수술한 전자간 골절 환자 중 6개월 이상 추시가 가능하였던 79명을 대상으로 하였다. 고정실패는 12례였으며, 고정실패에 관여할 것이라고 기대되는 다음 인자들에 대하여 분석하였다; modified Evans 분류, Singh 지수, 대퇴 골두내 나사의 위치, 골절의 정복양상, 이 인자들을 chi square test를 이용하여 통계적으로 분석하였다. 결과: 나이와 연령은 통계적인 차이를 보여주지 못했다 (p>0.05). 골절의 안정성을 기준으로 나눈 두 군데에서는 의미있는 빈도의 차이를 보여주었다 (p<0.05). 대퇴 골두내 나사못의 상방위 치한 경우와 골절의 수술적 정복 후 전후 사진상 5㎜ 이상 전위된 경우에도 의미있는 차이를 보여주었다 (p>0.05). 결론: 나이, 성별, Singh 지수는 고정실패에 영향을 주지 않았다. 고정실패에 영향을 주는 요소는 다음과 같다고 사료된다; 나사못의 골두내 상바위치, 불안정한 골절양상, 골절의 수술적 정복 후 방사선 전후 사진에서 보이는 5㎜ 이상의 피질골의 전위. Purpose: To evaluate the factors which might affect the loss of fixation after surgical treatment of intertrochanteric fracture with compression hip screw. Materials and Method: From February 1996 to February 2001, seventy nine cases of intertrochanteric fracture which we operated with compression hip screw was reviewed with minimal follow up for 6 months. There were twelve cases of loss of fixation. The cases were analyzed according to each factors which we thought to affect the loss fixation. The factors are fracture type by modified Evans classification, Singh index, placement of screw in femoral head, quality of reduction. Then we analyzed these factors with chi square test. Result: Difference between age group and sex were not thought to be statistically meaningful factors (p>0.05). There were difference of prevalence between two group divided by fracture stability (p<0.05). In cases of superior placement in femoral head, there were more loss of fixation. Displacement of cortex of proximal femur of radiologic AP view other than laterial view showed meaningful difference (p<0.05). Conclusion: Age, sex, Singh index did not affect the loss of fixation. But, next factors as follows affected the loss of fixation; Superior placement of hip screw, unstable fracture pattern, displacement of fracture site more than 5㎜ after reduction on radiologyc AP view.
