본 연구는 자막처리 동영상 프로그램이 청각장애 학생의 문어능력과 조사 및 서술어 사용능력에 미치는 효과를 알아보고자 청각장애학교 학생 4명을 연구대상으로 하였다. 연구결과를 토대로 얻은 결론은 다음과 같다. 첫째, 자막처리 동영상 프로그램 학습이 청각장애 학생의 문어능력 향상에 효과적이었다. 둘째, 조사사용에 있어서 사용빈도가 현저하게 늘고 올바른 사용 빈도도 향상된 것으로 보아 자막처리 동영상 프로그램 학습이 청각장애학생의 조사능력 향상에 효과적이라고 할 수 있다. 셋째, 서술어 활용에 있어서도 사용빈도와 올바른 사용 빈도에 있어서 향상을 보임으로써 자막처리 동영상 프로그램 학습이 청각장애학생의 서술어활용 능력을 향상시키는데 효과적이라고 할 수 있다. The purpose of this study was to investigate the effects of application video clip on students with hearing impairment of sentence understanding, expressing, a postpositional word and the predicate. The subjects of this study were 4 hearing impaired students of the special school for the hearing impaired in G city. The method of this study was providing the video clip which had been photographed, added captions, produced and edited. And I selected and used the 100 sentences from the text of the elementary school. The results of this study were as below. First, the result of the test which appears in K-NSST, materials to know, was effective on reading abilities. Even though we have a difficult situation to analyze the reading abilities of the one student, the reading and writing abilities was improved a little. Three students of the four couldn``t write a grammatically right sentence in post-test. But after the program the result shows us the improvement. Second, video clip program was effective on using a postpositional word and the predicate. We can see a little improved scores of the writing abilities as 0→3, 2→7, 0→2, 37→40.

Plasmacytomas are tumors composed of plasma cells of variable maturity, which are histologically identical to those seen in multiple myeloma. Ankylosing spondylitis is a chronic inflammatory disease, probably resulting from the interaction of a genetic predisposition involving HLA-B27 with an environmental event such as enteric bacterial infection. Multiple myeloma has been intermittently reported in patients with ankylosing spondylitis. It has been proposed that the protracted stimulation of immunocytes by inflammatory lesions on the mucosal surfaces of the gastrointestinal, respiratory tracts may be implicated in the pathogenesis of multiple myeloma in some patients. We observed a 23 year old male patient with a history of plasmacytoma who subsequently developed ankylosing spondylitis. He was diagnosed as plasmacytoma 4 years ago and took a radiation therapy. There was no previous report of ankylosing spondylitis following plasmacytoma. The relationship between two diseases is uncertain until now and further study should be needed.

This study questionnaires 166 inpatients and outpatients with stroke in 8 hospitals, including Wonkwang University Gwangju Korean Hospital from July 2 to 31, 2001 in order to find out the influence of general nature, smoking, drinking, obesity, and perception of saltness of patients with stork on the outbreak of stroke and to examine important factors by dividing into hemorrhagic and ischemic stroke. Finally, collected data is analyzed statistically, using SPSS 7.5 statistics package. This study reaches a conclusion as follows. 1. For general nature, 86(51.8%) patients have hemorrhagic stroke and 80(48.2%), ischemic stroke in the rate of 1.59:1(male:female), suggesting that male's outbreak is more than female's. Outbreak age is ranged from 20 years to 90 years in order of 60's, 50's, and 40's. 50's-60's accounts for more than half percentage. 2. For smoking, 73(71.6%) of male patients has smoking experience and their 562% has ischemic stroke. Their cross-analysis for hemorrhagic and ischemic stroke shows significant difference with $x^2=3.90$(p<0.05). 48.6% of patients with smoking experience is ranged from 1 to 10 a day in smoking quantity. 3. For drinking, 90(88.2%) of male patients has drinking experience and their 53.3% has hemorrhagicstroke. Their cross-analysis for hemorrhagic and ischemic stroke shows no significant difference with x2=3.40(p<0.1). 59.3% of patients with drinking experience is classified as a overdrinking group. 4. For obesity, low weight is 8(4.8%): normal, 111(66.9%): excessive, 40(24.1%), and obesity, 7(4.2%). In patients with hemorrhagic stroke, excessive weight and obesity are somewhat high(33.7%). The cross-analysis for male's hemorrhagic and ischemic stork by dividing BMI into more and less than 25 shows no significant difference with x=3.52(p<0.1). 5. For perception of saltness, 21(12.7%) patients eat flat: 76(45.8%) normally, and 69(41.5%), saltily. Many patients with ischemic stroke are classified as a group who eat saltily. The cross-analysis for male's hemorrhagic and ischemic stroke shows signifiant difference with x2=10.99(p<0.05). As this study has small sample and selects inpatient and outpatient in certain local hospital, it is difficult to generalize. But the cross-analysis of male's hemorrhagic and ischemic stroke shows signifiant difference in smoking and perception of saltness. Drinking and obesity are more important factors in hemorrhagic stroke and smoking and perception of saltness in ischemic stroke.

Purpose: The purpose of this study was to measure changes in the H-reflex and V wave under loading conditions (e.g. prone and standing position) and to investigate whether postural change would affect the H-reflex and V wave in post stroke hemiplegic patients. Methods: Thirty persons with hemiplegia resulting from stroke (20 males, 10 females) participated in this study. Electromyography (EMG) was used to electrically stimulate and record the soleus H-reflexes and V waves under various loading conditions. The normality of the distribution of each variable (H latency, $H_{max}/M_{max}$ ratio, $V_{max}/M_{max}$ ratio) was tested using the Kolmogorov-Smirnov test. The means of normally distributed continuous data were assessed by independent t-test (${\alpha}$=0.05). Results: There were statistically significant differences in $H_{max}/M_{max}$ ratio (p<0.01), $V_{max}/M_{max}$ ratio (p<0.01), H latency (p<0.01) among the prone and standing position. Conclusion: We found that the H-reflex and V wave in standing position was more active to weight bearing load than prone position.

국내 증권시장에서 외국인 채권투자의결정요인 분석

송원호 한국국제금융학회 2021 국제금융연구 Vol.11 No.2

본 연구는 2007년 – 2020년 동안 우리나라 증권시장에서 외국인 채권투자의 결정요인을 분석하였다. 본 연구는 다음 세 가지 측면에서 채권 자료의 이질성 (heterogeneity)을 고려한 점에서 기존 연구와 차별점이 있다. 첫째, 순매수를 분석하였던 기존 연구와는 달리 매수와 매도를 따로 구분하여 분석하였다. 분석결과 채권의 매수와 매도는 순매수에서 보이지 않는 이질적인 모습을 보여주었다. 둘째, 채권을 만기별로 구분하여 만기 1년 이하, 1년∼3년, 3년∼5년, 5년 이상 만기를 가진 채권을 따로 분석하였다. 분석 결과 만기에 따라 유의한 설명변수가 달랐다. 셋째, 마르코프-스위칭(Markov-switching) 모형을 사용하여 채권 투자 수준이 높은 국면과 투자 수준이 낮은 국면을 구분하였다. 분석 결과 국면에 따라 채권 투자는 서로 다른 결정요인을 가졌고, 경우에 따라 서로 다른 부호를 가지기도 하였다. 여러 다양한 설명변수 그룹들 중에서 글로벌 유동성 변수들이 가장 유의한 결과를 보였고, 그 다음으로 리스크 변수들이 유의했다. 개별 변수들 중에서는 VIX, MSCI한국비중, EMBI+, 대미환율 순으로 중요한 영향을 미쳤다. This paper analyzes the determinants of foreign investments in Korean bond market for the periods of 2007-2020. This study contributes to the literature in that it considers the heterogeneity of foreign investments data in three ways. Frist, previous studies analyzed net purchases of bond whereas this study distinguishes purchases and sales of bonds. Results show that purchases and sells of bonds behave quite differently from net purchases. Second, we distinguish bonds by maturity of less than one year, one to three years, three to five years and over five years. Results show that important determinants are different by maturity. Third, we define two regimes using the Markov- switching model by the amounts of investments. Results show that we have different determinants for each level and sometimes they have opposite signs. Among the variable groups considered, global liquidity variables are the most significant and risk variables follow. Individual variables are important in the order of VIX, Korean weight in MSCI, EMBI+, and Won/Dollar exchange rates among others.

박정현,김용남,송규호,유재영,Park, Jeong-Hyun,Kim, Yong-Nam,Song, Kyu-Ho,Yoo, Jae-Young 한국세라믹학회 2002 한국세라믹학회지 Vol.39 No.5

본 연구에서는 $PbO-TiO_2-SiO_2-BaO-ZnO-Al_2O_3-CaO-B_2O_3-Bi_2O_3-MgO$계의 유리를 $1,400{\circ}C$에서 용융시킨 후, 급랭, 분쇄하여 glass frit을 제조하였다. Glass frit 분말을 일축가압성형한 후 $750~1,000{\circ}C$의 온도범위에서 2시간 동안 소성 및 결정화 하였다. Glass frit의 결정화는 $750{\circ}$ 전후의 온도에서 시작되었고, 저온에서의 주된 결정상은 $Al_2O_3$와 hexagonal celsian($BaAl_2Si_2O_8$)이었다. 소성온도가 높아지면서 monoclinic celsian, $ZnAl_2O_4,\;Zn_2SiO_4,\;CaTi(SiO_4)O,\;TiO_24 등이 주된 결정상으로 나타났고, 특히 celsian은 hexagonal에서 monoclinic으로 상전이가 발생하였다. 그리고 15wt%의 PbO를 첨가한 glass frit에만 $PbTiO_3-CaTiO_3$ 고용체가 나타났다. 1MHz 대역에서 유전특성을 살펴본 결과 유전상수는 11~16이었고, 유전손실은 0.020 미만이었다. 그러나 15wt%의 PbO를 첨가한 glass frit의 경우는 $PbTiO_3-CaTiO_3$ 고용체 결정상의 존재로 유전상수가 17~26으로 높았고, 유전손실은 0.010~0.015로서 다른 조성들에 비하여 우수한 특성을 나타내었다. In this study, the glass frit of $PbO-TiO-2-SiO_2-BaO-ZnO-Al_2O-3-CaO-B_2O_3-Bi_2O_3-MgO$ system was manufactured. The glass was melted at $1,400{\circ}C$, quenched and attrition-milled. The glass frit powder was pressed and fired for 2h at the range of $750~1,000{\circ}C$. The crystallization of glass frit began at about $750{\circ}$ and at low temperature, the main crystal phases were hexagonal celsian($BaAl_2Si_2O_8$) and alumina. As the firing temperature increased, the crystal phases of monoclinic celsian, zinc aluminate, zinc silicate, calcium titanium silicate and titania appeared. And the increase of firing temperature led to transformation of hexagonal celsian to monoclinic. The only glass frit containing 15wt% PbO had the crystal phase of solid solution of $PbTiO_3-CaTiO_3$. At the frequency of 1 MHz, the dielectric constant of glass frit crystallized was in the range of 11~16 and the dielectric loss less than 0.020. But the glass frit containing 15wt% PbO had the dielectric constant of 17~26 and loss of 0.010~0.015 because of crystal phase of solid solution of $PbTiO_3-CaTiO_3$.

Family and parents which serve as a primary group for the children's development also play important role in their cerebral palsy children's treatment. This study wants to know how the parents' participation in their children's physical therapy and satisfaction degree have an impact on their children's improvement of the motor function. For that purpose, a home made self filling survey was conducted of 156 cerebral palsy children's parents whose children were treated in 4 university general hospitals and 3 welfare centers from the 1st of April 2004 to the 31th of march 2005. The gross motor function was employed to evaluate the cerebral palsy children's motor function improvement. In this study, those questioned were divided into two groups according to the time of treatment. 'Group A' is consist of the patients whose parents attended to the treatment more than one hour at home. The patients who belonged to 'Group B' were treated less than one hour at home. The general features of the cerebral palsy children and their parents and the characteristics of their physical disability, the parents' participation and their satisfaction degree were examined by survey. Evaluating the difference between two groups' motor function according to their parents participation degree in the physical therapy leads to the following results. First, 'Group A' was better than 'Group B' in their satisfaction degree with the physical therapy and participation degree. Statistically 'Group A' was superior to 'Group B' in the requirements of the information and education for the children with cerebral palsy. Second, after two months of treatment, 'Group A' showed more statistically significant improvement than 'Group B' in every items as like lying in item 1, sitting in item2, crawling and kneeling in item 3, standing in item 4, walking,running, jumping in item 5. Third, parents' participation in physical therapy and satisfaction degree have some relevance to their children' motor function improvement. The satisfaction degree is related to motor function like crawling and kneeling in item 3, walking,running, jumping in item 5. It is showed that the parents' participation degree and information about handicapped children.
