The purpose of this paper is to examine how Korean learners of English reset the “prodrop”parameter of Korean into “non-prodrop” parameter of English in the process of English acquisition. An experiment was conducted to 45 Korean learners of English on the prodrop phenomenon, namely on the null referential or null nonreferential subject, and subject-verb agreement by way of grammatical judgment. The results of the experiment are as follows: First, L2 learners follow the parameter of L1, and then reset the parameter of L2 regardless of the parameter of L1 as their L2 abilities advance. Thus, this study provides further support for the hypothesis that universal grammar is available via L1 Second, the referential subject is, at first, easier to acquire than nonreferential subject, and the triggering fact for the switch from [+prodrop] to [-prodrop]was the use of nonreferential subjects. Third, 3rd person agreement has no connection with the acquisition of the prodrop parameter has no connection with the acquisition of the prodrop parameter as a result of subject-verb agreement. Therefore, these results indicate that verb agreement is not a trigger for the recognition of the obligatory null subject.

최근에 이르러 건축구조물의 고층화, 다양화, 공사현장의 품질관리의 증진 그리고 혼화제의 개발에 따라 콘크리트의 고강도화가 실효성을 가져오기에 이르렀다. 본 연구는 현재 레미콘공장에서 사용하고 있는 여러가지 재료를 이용하고 배합설계를 통하여 고강도콘크리트 실용화에 따른 다양한 문제를 해결하려는데 목적을 두었다. 특히, 본 연구결과에서 슬럼프 10㎝, 고성능감수제(2.0%), 부순골재 약 20㎜, 그리고 W/(C+SF) 25%, 보통 포틀랜드 시멘트의 배합상태에서 700∼800㎏/㎤ 강도를 얻을 수 있었다. 따라서 본 연구의 여러 가지 실험데이타는 앞으로 레미콘회사에서 고강도 콘크리트를 생산하는데 많은 참고와 도움이 될 것으로 기대된다. Recently, it is fairly easy to make high strength concrete according to high-rising of buildings, improvement of field supervion, and development of water reducing admixtuer (high range water reducer). The objective of this paper is to solve the various problems related to the practical use of high strength concrete by use of materials and mix proportion design as used in the remicon company. From the result of this experiment, it is found that the high strength concrete (more than 700∼800㎏/㎤) can be obtained by using slump(10㎝), high water reducer (2.0%), crushed stone (about 20㎜), and water-cement ratio(W/C+SF):25%) with common portland cement. The results of this paper are expected to be helpful in producing of high strength concrete at remicon company.

This experiment was carried out to investigate the effect of hardening materials, which were silicate complex fertilizer for the basal fertilization which contained 25percent SiO2, 45percent Ca, and 2percent Mg, Calcabon wettable powder for the foliar spray which contained 95percent calcite and 5percent surfactant, and Neo-Cal for the forliar spray which contained 17percent chelate calcium, to strengthen the stem hardness on lily(Lilium spp. 'Con Amore'). Among the treatments, the growth of the treatment of basal fertilizer on silicate complex was better than that of the other treatments. On the shear test of stem hardness, the hardness on the treatment of basal fertilizer on silicate complex was higher than that on the other treatments and the control was the lowest. And on the puncture test of stem hardness, the pattern among the treatments was He same on the shear strength. Mineral contents of leaf were higher than those of stem, and the contents of Ca and Si on the treatment of basal fertilizer on silicate complex were 1.07percent and 1.25percent, respectively, and these contents were higher than those of the other treatments.

항응고제 치료의 주된 합병증은 출혈로서 주로 뇌실질과 복강 내에 발생하며 사지 근육에 발생하는 근육내 혈종은 매우 드문 것으로 알려져 있다. 이러한 항응고제 치료 후 발생하는 자발성 근육내 혈종은 발생빈도가 드물 뿐 아니라, 심부정맥혈전증과 그 증상이 유사하여 감별하기가 쉽지 않다. 저자들은 항응고제 치료 후 운동 마비가 발생한 사지 근육에서 자발성 근육내 혈종이 발생한 증례를 경험하여 이를 보고한다. Spontaneous intramuscular hematoma(SIH) is an uncommon but serious bleeding complication of anticoagulation therapy that has received little attention. We present a patient of spontaneous muscular hematoma during anticoagulation therapy for acute stroke management. A-74-year old man was admitted with sudden onset of dysarthria and left hemiparesis. Brain MRI and MRA showed acute cerebral infarction along right middle cerebral artery territory and severe stenosis of right proximal cervical internal carotid artery. During intravenous heparin treatment, he complained acute pain and swelling on left leg. Muscular CT showed enhancing focal soft tissue mass on left gastrocnemius muscle and ultrasonography demonstrated multiple hematomas on left gastrocnemius muscle. Treatment of heparin was stopped immediately. After conservative management for hematomas, symptoms were subsided.

움직임 궤적에 급격한 변화가 있는 영상자료에 대한 Digital filter, Spline, Wavelet의 평활화 비교

The purpose of this study was to evaluate the smoothing methods and to find optimal smoothing parameter. The used smoothing methods are cubic smoothing spline. digital filter and wavelet. At first. Using the cosine function and noise function. theoretical data were made. Each smoothing methods with various parameters were applied to the data which were made with normally distribed noise and equally distributed noise, and the various speed ratios and the relative angles between before and after of impact. Next time we use the method with optimal parameter to the experimental data. according to the speed ratio and the relative angle between before and after of impact. 1. The optimal smoothing method was not specific to the state of impact. So. there are the other factor as well as the speed ratio and the relative angle between before and after of impact to specify the state of impact. 2. Variation of parameter of smoothing according to the state of impact was large on spline method and digital-filter method. but it was small on wavelet method. So, wavelet method can be used to smooth the various kinds of data without cautions.

The purpose of this study is to find out the effectiveness of the massage program applied to the patients with frozen shoulder by measuring, assessing and analyzing the changes in pain and range of motion(ROM) before and after massage program. Surveyed from Jan. 2001 to December 2002 were 104 patients suffering from frozen shoulder. In the rehabilitation massage program, such methods as Effleurage, Petrissage and Deep transverse friction were selected as they are among traditional massage treatments frequently used for joints with pain and restricted ROM. Effleurage and Petrissage were applied for 20 minutes in total before and after Deep Transverse Friction. After massage program, the intensity and unpleasantness of pain were measured and analyzed by means of VAS(visual analogue scaleH and VAS-U, while ROM was measured and analyzed by using Goniometer. The major findings from this study are as follows; 1. There was significant decrease in the intensity of pain and unpleasantness of pain after rehabilitation massage program(p<.05). 2. There appeared, however, significant increase in ROM after rehabilitation massage program(p<.05). 3. From the analysis into chronological changes in ROM before and after rehabilitation massage program with ANOVA, it became evident that the longer the period of treatment was, the higher the ROM increases drastically, while significant difference was shown in Abduction and in External and Internal Rotation(p<.05). Summed up, it can be generally concluded that rehabilitation massage program is an effective treatment to rid the patients with frozen shoulder of pains safely and promptly. From the above outcomes, it was revealed that rehabilitation massage program has proven to reduce the pains, exercising huge influence to increase ROM. It is, therefore, suggested to continue and expand the study on the cure of frozen shoulder and to motivate patients, orthopedists, physiatrists, physiotherapists, and sports massagists etc. to consider massage program as safest and most efficient pain remedy.
