The physical therapist's participation in community based rehabilitation(CBR) is necessary, in a variety of ways, to ensure the disabled quality service. Although CBR needs the Physical Therapist's help, participation is limited due to unstable CBR policy, and because there is a lack of financial support, skilled Physical Therapist's are usually not hired. Physical Therapist's themselves do not seem to completely understand this. The experts active participation is needed for effective rehabilitation service. Therefore, the trained Physical Therspist's participation is absoutely necessary is CBR policy if it is even to provide completely effective service.

최근 들어, 이동 객체의 위치 정보를 이용한 응용의 등장으로 시공간 데이터베이스를 위한 인덱스 기법의 중요성이 점차 커지고 있다. $TPR^*$-트리는 미래 시간 질의의 효율적인 처리를 위하여 가장 널리 사용되는 인덱스 구조이다. $TPR^*$-트리는 CBR(conservative bounding rectangle)의 개념을 이용하여 이동 객체들의 미래 위치의 범위를 추정하는 방식을 사용한다. 그러나 CBR은 시간이 지남에 따라 지나치게 확대 됨으로써 질의 처리 성능을 크게 저하시키는 문제를 야기시킨다. 본 논문에서는 능동적인 CBR 재조정을 통하여 이러한 CBR의 지나친 확대를 방지하고, 이 결과 $TPR^*$-트리의 질의 처리 성능을 개선할 수 있는 효과적인 기법을 제안한다. 제안한 기법은 질의 처리를 위하여 $TPR^*$-트리의 단말 노드를 액세스한 시점에 CBR 재조정의 필요여부를 점검하도록 함으로써 이러한 점검을 위한 추가적인 디스크 액세스 비용을 요구하지 않는다. 또한, CBR의 재조정이 필요한가의 여부를 판정하기 위하여 재조정을 위한 추가 비용과 향후의 질의 비용을 모두 고려하는 새로운 비용 모델을 정립한다. 제안된 기법을 통하여 갱신이 자주 발생하지 않는 경우에도 CBR의 비정상적인 확대를 방지할 수 있다. 제안된 기법의 성능 개선 효과를 정량적으로 검증하기 위하여 다양한 실험을 수행한다. 실험 결과에 의하면, 제안된 기법은 질의 처리 시 기존 기법과 비교하여 최대 40%이상의 성능 개선 효과를 보인다.

포장하부구조의 지지력을 평가하기 위해 많이 사용되는 방법은 평판재하시험(Plate Bearing Test) 현장 CBR시험(California Bearing Ratio Test) 등이 있으나, 시험을 수행하는데 있어 많은 인력과 시간이 소비되는 단점이 있어, 많은 연구자들은 현장에서 포장하부구조의 강성을 측정할 수 있는 간편한 방법으로 동적 콘 관입시험(Dynamic Cone Penetrometer Test)을 제안하였다. 이에 본 연구에서는 DCP의 현장적용성을 평가하기 위해, 총 4개 현장의 노상층과 보조기층에서 DCP, 평판재하시험, 현장CBR시험, FWD시험을 동시에 수행하여 그 결과를 상호 비교 분석하였다. 그 결과 DCPI, $M{FWD},\;PBT\underline{\;}K_{30}$은 서로 일정한 상관관계가 존재하는 것으로 나타났으나, CBR은 다른 결과 값들과 비교한 결과 상관관계가 매우 낮은 것으로 나타났다. 본 연구에서는 이 결과로부터 $DCPI-M_{FWD},\;DCPI-PBT\underline{\;}K_{30}$ 관계식을 다음과 같이 제안하였다. $$M_{FWD}=993.10\Big(\frac{1}{DCPI}\Big)+33.95\;R^2=0.774$ $$M_{FWD}=3.7533K_{30}+23.085\;R^2=0.69$$

Case- based reasoning(CBR) offers a new approach for developing knowledge based systems. Unlike the rule-based paradigm, in which domain knowledge is encoded in the form of production rules, in the case-based approach the problem solving experience of the domain expert is encoded in the form of cases stored in a casebase(CB). CBR allows a reasoner (1) to propose solutions in domains that are not completely understood by the reasoner, (2) to evaluate solutions when no algorithmic method is available for evaluation, and (3) to interprete open-ended and ill-defined concepts. CBR also helps reasoner (4) take actions to avoid repeating past mistakes, and (5) focus its reasoning on important parts of a problem. Owing to the above advantages, CBR has successfully been applied to many kinds of problems such as design, planning, diagnosis and instruction. In this paper, I propose case-based DSS(CBDSS). CBDSS is an intelligent DSS using CBR technique. CBDSS consists of interface, case-based reasoner, maintainer, casebase management system, domain dependent CB, domain independent CB, and so on.

During the homolytic reactions of $CCl_4$ or $Cl_3CBr with ${\beta}-halo^1$-styrenes,$\beta$-haloradicals are key intermediates. They are to be stabilized via three pathways; $\beta$-cleavage, halogen transfer and telomerization. The three reaction paths are delicately controlled by the energetics of their formation and stabilization. When the formation of a $\beta$-haloradical is accompanied by considerable excess of energy from an exothermic reaction, $\beta$ -cleavage is often dominant over the halogen transfer. On the other hand, if the radical forms via a reversible reaction, two processes become competitive. $\beta$-Eliminated bromine atoms from ${\beta}$ -bromoradicals generate $Br_2$ via $Cl_3CBr + {\cdot}Br {\leftrightarrow} Br_2 + {CCl_3}{\cdot}{Br_2}$ may act as a better scavenger than Cl3CBr for the ${\beta}$-bromoradicals. Different reactivities of chlorine, bromine and trichloromethyl radicals towards olefinic pi-bond are clarified in terms of the beat content of the addition reactions.

We have studied the blending effects of cis-1,4-polybutadiene (CBR) and styrene-tutadiene rubber at various blending ratios of 100 : 0, 70 30, 50 : 50, 30 : 70, 0 : 100, and of carbon black ISAF and HAP at various compounding ratios of 45 PHR, 55 PHR, 65 PHR, for tyre tread rubber. The results obtained are summerized as follows; 1. For tyre tread rubber, it was found to increased efficiency to use SBR polymer only than to use the blending ratio CB/SBR=30/70 below. But it was observed that the latter was adapted for the bus or truck tyre and the former for the passenger tyre. 2. Excellent efficiency was obtained in case of carbon black compounding ratio of 55%, and also the compounding of ISAF made better efficiency than that of HAF. 3. Carbon black was more efficient to SBR than to CB. 4. For the aging ratio, the compounding rubber of NR was the highest, and the ratio was decreased in order of the compounding rubber of oil-extended SBR or CB polymer only, the compounding rubber of non oil-extended SBR or CB polymer only, and the blending rubber.

To survey the recognition of Community Based Rehabilitation (CBR) by Public Health Center(PHC) Physical Therapists in Kyoungki Province. This study analysed general characteristic of Physical Therapists and congnition, participation, education, problems and requireanents for CBR. The objects of this study were 37 therapists who work at 27 of 39 PHC in Kyoungki province and data was collected for 20days from Jan. 12 to 31. 1998 and the results computed from 32 responses. First, Female therapists outnumber males. The age category 30 to 35 old represneted $56.2\%$ of the total number studied. $59.4\%$ of therapists had worked more than 7 years and therapists usually$(46.9\%)$ worked from 6 month to 2 years at the PHC. Junior college graduates were $84.4\%$, and respondents with family responsibilirt were $65.6\%$. Second, Recently pain control has become the major requirment of patiants at PH$(53.1\%)$. If they offered expaneded services - a rehabilitation program $(53.1\%)$, home vistation $(31.3\%)$. when asked about a working guide book, nobody had one. Third, $68.7\%$ of therapists were aware of the present level of CBR, $40.9\%$ of them had gotten an information from educated colleagues, and $68.7\%$ of therapists were aware of the present level of CBR, $86.4\%$ of therapists felt responsible to provide rehabilitation Fourth, For CBR, $93.7\%$ had positive ideas in which they could participate. $73.3\%$ wished to composed a team of various rehabilitational specialists. $73.3\%$ wished for the meeting day to be flexible and $86.6\%$ desired to meet once or twice a week. Fifth, Almost all$(96.9\%)$ desired more educational opportunity about CBR. Example, once or twice a year$(56.2\%)$ and training period of 4-7 days $(43.7\%)$. They wanted to learn theory and practice together$(74.2\%)$ and $74.2\%$ wanted the mational multi-rehabilitation center as a educational managing organization. Sixth, The most important requirment for accomplishing CBR by physical therapists was job security and an adequate number of therapists$(84.4\%)$ Required number of physical therapists in the PHC was 3 $(43.7\%)$. The cooperative agency should be the district goverment organization $(56.2\%)$. Factors inhibiting the execution of CBR were lack of administrative support, physical therapists, and equipments for pain control and for therapeutic exercise.
