      • 18–30세 사이에 발생하는 뇌경색의 특징, 다기관 레지스트리 연구

        장윤경,송태진,김용재,허지회,이경열,김영은,장민욱,조수진,강석윤 이화여자대학교 의과학연구소 2017 EMJ (Ewha medical journal) Vol.40 No.3

        Objectives: Although there have been several reports that described characteristics for young age stroke, information regarding very young age (18–30 years old) has been limited. We aimed to analyze demographic factors, stroke subtype, and 3-month outcome in acute ischemic stroke patient who have relatively very young age in multicenter stroke registry. Methods: We evaluated all 122 (7.1%) consecutive acute ischemic stroke (within 7 days after symptom onset) patients aged 18 to 30 from 17,144 patients who registered in multicenter prospective stroke registry, 1997 to 2012. Etiology was classified by Trial of Org 10172 in Acute Stroke Treatment criteria. Stroke severity was defined as National Institutes of Health Stroke Scale (NIHSS) and stroke outcome was defined by modified Rankin scale (mRS) at 3 months after index stroke. Results: The mean age of all included patients was 25.1±3.7 years and 76 patients (62.2%) were male. The median NIHSS at admission was 4. Considering stroke subtype, 37 patients (30.3%) had stroke of other determined etiology (SOD), 37 (30.3%) had undetermined negative evaluation (UN) and 31 (25.4%) had cardioembolism (CE) were frequently noted. After adjusting age, sex and variables which had P<0.1 in univariable analysis (NIHSS and stroke subtype), CE stroke subtype (odds ratio, 4.68; 95% confidence interval, 1.42–15.48; P=0.011) were significantly associated with poor functional outcome (mRS≥3). Conclusion: In very young age ischemic stroke patients, SOD and UN stroke subtype were most common and CE stroke subtype was independently associated with poor discharge outcome.

        Background/Aims: Inflammatory diseasas of the pancreas are not uncommon. The advanced age is one of the significant factors in assessing the severity of acute pancreatitis. It has been shown that the biliary tract disease is a more frequent cause of acute pancreatitis in the elderly than in the young. With the increased life span, the elderly are comprising a large proportion of the population. As a result, physicians are more often being faced with acute pancreatitis in the elderly. The purpose af this study was to evaluate clinical features of acute panereatitis in the elderly. Methods: A total of 188 patients with acute pancreatitis were reviewed. We investigated the differences of clinical characteristics between the elderly patients aged over 60 and the young patients aged under 60. Results: The sex distribution showed male preponderance in the young patients (M:F=2.4:1), but was nearly equal in the elderly patients (M:F=1.1:1). The most common cause of acute pancreatitis in the elderly was biliary tract disease (52.5%), while alcohol abuse was the most common cause in the young patients (38.8%), Local complications of acute pancreatitis, such as psuedocyst, necrosis, abscesses were not differently shown between the elderly (16.9%) and the young (20.2%) patients. Systemic complications including acute puhnonary failure occurred more frequently in the elderly patients than the young patients. The mortality rate of the elderly patients (5.1%) was not significantly different from that of the young patients (3.1%). Conclusions: To detect correctable underlying bihary tract diseases the elderly patients with acute pancreatitis should be completely investigated using endoscopic retrograde cholangiopancreatography (ERCP). In addition, the patient should be closely monitored for the development of the systemic complications during the disease process.

        식물생장조절제 Seaweed extracts(GA14)의 수도 품종간 생육 및 수량에 미치는 효과

        송재영,김용일,박보영,정재영,최현구,정종태,이희봉 충남대학교 농업과학연구소 2004 농업과학연구 Vol.31 No.1

        This study was carried out to identify the effects of seaweed extracts(GA14) on growth of two rice cultivars, Junambyo and Donganbyo. Seedling qualities of two cultivars were better in all items including heading dates at early stage treated at seedling plus 2-3 leaf stages than at single treatment of seedling. Ripening ratio of Junambyo in paddy field was increased 0.3% by seaweed extracts(GA14) treatment, but that of Donganbyo decreased 0.5%. 1,000 grain weight of Junambyo and Donanbyo by seaweed extracts(GA14) treatment was two to four grams higher and the yield of two cultivars was also higher by three to four percent. Appearance characters of two rice cultivars was high in head, while damaged, chalky and crack rate were low at seaweed extracts(GA14) treatment. Protein, moisture and amylose characteristics related to table quality of Junambyo were not different by seaweed extracts treatment, but table values was high in only treatment. Donganbyo was also similar to Junambyo, but table quality was slightly high at non-treatment.

        N/A Objectives: Mutations in the glucokinase (GCK) gene are considered a possible cause of maturity-onset diabetes of the young. The purpose of this study was to evaluate the contribution of this gene to the development of non insulin dependent diabetes mellitus (NIDDM), gestational diabetes mellitus (GDM) and post-renal transplantation diabetes mellitus (PTDM). Method: Identification of GCK mutation was attempted on 39 NIDDM patients, 2 GDM patients and 58 selected renal allograft recipients with PTDM and 45 normal controls. The exons in the GCK gene were examined by polymerase chain reaction (PCR), followed by analysis of single-stranded DNA conformational polymorphism (SSCP). The abnormal bands were also confirmed by DNA sequencing analysis. The exons of affected family members were also investigated for mutations of the GCK gene. Results: Two of the 58 PTDM patients (3.4%) were found to have CKK mutations. One had the mutation on exon 5 and the other on intron 7. One control subject had the mutation on intmn 9. The mutation of exon 5 was identified as a substitution of CCT (proline) for CTT (leucine) at codon 164, which has not ever reported before. The family members of the PFDM patient with mutation of exon 5 were analyzed by PCR followed by SSCP, and two of them revealed the same mutation. The abnormal band on the SSCP analysis of exon 7 was identified as the insertion of base C/T at the 39th nucleotide in intron 7. Two family members of this patients also had same band on SSCP. The one mutation of 45 normal controls was CT located at the 8th nucleotide in intron 9, which was a common polymorphism. Conclusion: We found GCK mutations in subjects with PTDM and we speculate that these mutations may be one of the contributing cause of PTDM.

        기억력 저하를 호소하는 노인들을 대상으로 INM176를 3개월간 임상시험한 후의 치료성적 및 부작용 평가 보고

        김지혜,고선규,고효정,권영아,김성환,김재경,김태은,박재우,서민영,송영란,이인수,김도관 大韓神經精神醫學會 2003 신경정신의학 Vol.42 No.2

        Objectives : We examined the effects of INM 176 (K-l107) compared with placebo on the cognitive functions of 92 old aged subjects with cognitive impairment. Methods : This was a prospective, 12 week, double-blind, Placebo-controlled clinical trial. The elderly who achieved a score of less than 25 points on the K-MMSE or showed a high risk of Alzheimer's disease from the 7-Minute Neurocognitive Screening Battery were considered to have objective impairment and were selected as subjects for this study. The subjects were randomized to placebo or INM 176 group. The outcome measures were from the Alzheimer's Disease Assessment Scale-cognitive subscale (ADAS-Cog), the Instrumental Activities ofDaily Living (IADL) and the Korean Geriatric Depression Scale (KGDS) and two kinds of computerized priming tests. After setting the total error score in the Alzheimer's Disease Assessment Scale-Cognitive section (ADAS-cog) as the repeated measurement factor, an analysis of variance of the combined factor design was done between the placebo and INM 176 group. Results : The interaction effect of time (pre- and post-trial) and group (placebo and INM 176 group) was significant in the analysis of the ADAS-cog's total error score. The INM 176 group's total error score in the ADAS-cog decreased significantly (p<0.01), whereas the placebo group showed a slight increase. The mean changes in IADL and GDS from baseline scores favored in the INM 176 group than in the placebo group. Outcome changes ofADAS-cog, IADL, KGDS scores during the 12 week clinical trail ofINM 176 and placebo demonstrated favorable responses in the INM176 administered group. Conclusions : This is a preliminary clinical trial result of INM176 as a memory pill. Based on these results, INM176 may be a candidate molecule for the improvement of cognitive functions, including memory, Further clinical trial should demonstrate its efficacy.

      • Baculovirus를 이용한 Aujeszky's Disease Virus gⅢ 단백질 발현

        송재영,이중복,현방훈,박종현,김병한,권창희,전무형,안수환 충남대학교 생물공학연구소 1993 생물공학연구지 Vol.3 No.-

        The g Ⅲ gene located in U_L region of Yangsan strain, a field isolate of Aujeszky's disease virus (ADV) in Korea, was cloned into pTZ18R and sequenced. The gⅢ gene consisting of 1,437 nucleotides showed 98% sequence homology with that of Becker strain, a reference strain of ADV. The gene encoding gⅢ of Yangsan strain was placed under the control of Autographa californica nucleopolyhedrosis virus (AcNPV) polyhedrin promoter, and expressed by the derived recombinant baculovirus using Spodoptera frugiperda 9 (Sf9) cells. The expressed gⅢ was a protein with molecular weight of 72kd determined by immunoprecipitation and Western blotting assay using anti-ADV polyclonal antibodies and anti-gⅢ monoclonal antibody. The partially purified gⅢ protein was utilized as antigen in the radial immunodiffusion enzyme assay (RIDEA) to detect to specific antibody against ADV in pig sera. The results indicated that the sensitivity of RIDEA with the recombinant gⅢ protein antigen (98%) was as high as that with the conventional glycoprotein antigen extracted from the ADV infected cells. In addition, the false positive and false nagative reactions in gⅢ RIDEA were significantly reduced than the conventional glycoprotein RIDEA as judged from the results of standard serum neutralization test.

      • 대학생의 여가활동에 대한 연구

        송재영 순천향대학교 학생상담센터 2001 學生生活硏究 Vol.8 No.-

        This research was performed to investigate and analyse the leisure activities of university's students for the purpose that the analytical results would be contributed to students' life guidances and leisure education within the university and the related institution. In addition, this study will be used as the necessary basic material to establish and improve student policy, program planning and managements in their leisure education and student's life guidance. Students were asked to respond to the questionnaire that consisted of 5 categories concerning general information of the responding students, how much leisure time, what type and item of the leisure activity and the students' consciousness of their leisure life. The sample for the study were collected from 311 students at Soonchunhyang University and each 100 students of R and H University. The responses for this sample were statistically analysed by using of SPSS/PC+. The results of the research were as follows: It was found that the university students spent 10.42 hours(43%) on biologically necessary activities, 8.37 hours on studying activities and 5.22 hours for the leisure activities in a day from monday to friday and each 10.58(44%), 3.65(15%) and 9.77(41%) hours respectively in a day of weekend. It was also revealed that the students participated in the field of the "social intercourse activity" most frequently and "viewing and appreciation activity" was the next one among 6 activities. "Watching T.V. and listening to the radio" was selected as the most enjoyable leisure items and the items of "conversation with family members or friends", "computer game and internet chatting", "reading books" and "art and literary activity", "walking" and "playing in the PC room or electronic game room" were the next places in order. It seemed to be the remarkable that relatively fewer students(69%) participated in the leisure types of sports compared to the other types. But much of the students expressed that they wanted to participate in the field of sports in the future, in which male students wanted to engage in one sports everyday continuously, but female students preferred to participate in various items extensively. As to the conditions of students' leisure activities, it was showed that university campus was the best place to enjoy the leisure activity during the weekdays and the location area of students' dwelling house during weekend. The outcomes showed that the students seemed to spend their leisure time with their college friends during weekdays, while middle or high school friends did during weekend. The most important factor affecting to the leisure activities was founded to be the students' willingness to do them and it appeared that the other conditions such as the money, places, facilities or time couldn't do anything with the leisure activities. Concerned about the students' consciousness of the leisure activities in their social lives, most of the students valued both the economic activities and the leisure ones as the one of the more valuable things in human life, rather than the religious or social service activities. And it concluded that students considered leisure activities in their university campus a preparatory process for the future's healthy leisure activities.

      • 관계데이터베이스에서의 다치종속성의 결정문제에 관한 연구

        宋榮宰,羅仁燁 慶熙大學校 1987 論文集 Vol.16 No.-

        Database theory has recently been developing rapidly as a field of wide range closely related to a variety of fields. Especially, of the dependency theories of relational database, a recent trend considered important has been studied. Relational database has been represented by Functional Dependency (FD), Multi-valued Dependency (MVD), Join Dependency (JD), etc.; these, however, have problems of semantic constraint because they deal mainly with the relations of the entity of attribute. In this thesis, I have studied a new concept of constraint: Constraint MVD which makes it possible to deal with semantic constraint with which MVD, FD, and JD in relational database were unable to deal in models. Thus, a partial constraint of database maintaining the whole constraint, the expression of the dependency of data can be put to efficient use and updating operation of database can be reduced. The introduction of MVD has elucidated problems involved therem in. and I have presented a method of expression by which data in a schema can satisfty the dependency included the dependency set. The gradually wide-spreading use of computes in our daily life will make database match man's memory: and it is expected that the dependency for the use of computers to increase will read to a continued study of database with will go beyond the functioning fo man's memory and will eventually give rise to a theoretical system to formulate paralled and distributed processing and other data models.
