배경 및 목적: 본 연구는 전자구개도를 사용하여 한국어의 치경마찰음인 /ㅅ/와 /ㅆ/를 조음운동적 측면에서 비교 분석해보고, 치경마찰음 조음 시 나타나는 혀-구개 접촉에 관한 정보를 제공하기 위한 목적으로 시행되었다. 방법: 한국어가 모국어이며 발음에 문제가 없는 정상 성인 5명이 전자구개도를 착용하여 치경마찰음을 분절음 차원에서뿐 아니라 단어 내 위치 및 모음문맥을 달리하여 녹음한 후 팰라토그램을 분석하였다. 결과: 그 결과, /ㅅ/와 /ㅆ/는 협착의 너비와 혀-구개 최대접촉구간에서 유의한 차이를 보였다. /ㅆ/에서 협착의 너비가 더 좁고 전체 혀-구개 접촉구간은 더 넓게 나타났다. 단어 내 위치에 따른 차이는 유의하지 않았지만, 고모음인 /ㅣ/ 문맥에서는 저모음인 /ㅏ/에 비해 협착의 위치가 후방화되었으며, 지속시간도 가장 긴 것으로 나타났다. 또한 혀-구개 접촉 구간도 가장 넓게 나타났다. 논의 및 결론: 본 연구는 전자구개도를 사용하여 한국어 치경마찰음의 혀와 구개 접촉에 관한 정보를 제공했다는 점에서 그 의의를 갖는다. 또한 본 연구의 결과는 한국형 전자구개도의 개발의 기초자료로써 그 의미가 있다. Objectives: The present study is aimed an electropalatographic investigation of Korean fricatives /s/ and /s*/. All data from this study is based on the production of 5- adult speakers who speak Korean as their first language. Methods: Electropalatography (EPG) is an instrumental technique for showing tongue and palate contact during speech. The participants recorded /s/ and /s*/ in CV (/si/, /sɑ/, /su/, /s*i/, /s*ɑ/, /s*u/) and VCV (/ɑsi/, /ɑsɑ/, /ɑsu/, /ɑs*i/, /ɑs*ɑ/, /ɑs*u/) context using EPG and then, four variables were analyzed: row of medial groove (RMG), medial groove width (MGW), medial groove length (MGL), and maximum contact frame (MCF). Results: There was significantly greater medial groove width and maximum contact frame for / s*/ compared to /s/. The difference between /si/ and /sɑ/ was also found in the row of medial groove, medial groove width and maximum contact frame. /si/ was produced further back, and had a longer medial groove length. Also, it showed more total tongue-palate contact than /sa/. Conclusion: A various range of palatal contact patterns were found between typical adults for perceptually normal /s/ and /s*/. The results provided the information about tongue–palate pattern of Korean fricatives /s/ and /s*/. These findings would be utilized to build the basic data and useful information for Korean EPG system.

It has been reported several viral diseases in soybean. The occurrence of Bean common mosaic virus and Peanut stunt virus are able to induce severe problem because the main breeding target for viral disease was focused on Soybean mosaic virus. BCMV is a spcies of the genus Potyvirus of the family Potyviridae. BCMV reduces yield by as much as 80% and also adversely affects seed quality in common bean. BCMV has a worldwide distribution because of its high rates 35% of transmission via seeds produced by plants systemically infected prior to bloom. PSV is a species of the genus Cucumovirus of the family Bromoviridae. PSV has been reported to be economically damaging on beans worldwide. Although the virus is reportedly seed transmissible at very low rates, infected plants rarely produce pods with normal viable seeds. The most satisfactory management method of viral diseases such as BCMV and PSV is the use of resistant cultivars and healthy seed. For the overcome of genetic resistance by new virus such as BCMV and PSV, virus diseases monitoring and researches need to study deeply and continually. In this study, we conducted the resistance screen on BCMV and PSV for selection of resistance cultivars. We inoculated on 128 cultivars with PSV and BCMV respectively. These cultivars were classified through pathogenic response such as resistance, necrosis and susceptibility. In addition, 99 and 66 resistant cultivars were confirmed against PSV and BCMV respectively.

콘크리트 보수용 폴리머 복합재료의 접착강도 특성

신영수,연규석,이윤수,지경용 강원대학교 부설 석재복합신소재 제품연구센터 1999 석재연 논문집 Vol.4 No.-

이 연구는 기존 시멘트 콘크리트 구조물의 표면층과 보수용 폴리머 모르터의 접착강도 특성을 구명키위해 폴리머 결합재의 종류, 결합재 첨가량, 모재의 표면상태를 변수로하여 실험한 것이다. 폴리머 시멘트 모르터제조에 상용된 재료는 시멘트 혼화용 폴리머로서 styrene-butadiene rubber (SBR)를 사용하였고, 폴리머 모르터의 결합재로는 에폭시 수지 (EP)와 불포와 폴리에스터 수지 (UP)를 사용하였다. 실험결과 모재가 건조상태인 경우 습윤상태보다 강도가 높게 나타나 모재의 상태가 건조한 것이 접착강도에 유리한 것으로 나타났으며, 폴리머 시멘트 모르터가 폴리머 모르터에 비해 접착강도가 낮음을 알 수 있었다. The adhesion properties of polymer mortars for cement concrete repair were evaluated with respect to polymer types, binder ratios and the surface conditions of cement concrete substrate. Styrene-butadiene rubber (SBR) was used as an additive for polymer cement mortar and epoxy resin (EP) and unsaturated polyester resin (UP) were used as binders for polymer mortars. The adhesion strength of polymer cement mortar was smaller than that of polymer mortar. The adhesion strengths to the dry surfaces of substrate were larger than those to the wet surfaces, indicating that the dryness of substrate increased the adhesion strength in repairing concrete structures.

Alpha-fetoprotein(AFP) is a major plasma protein synthesized by the fetal liver, york sac, and gastrointestinal tract. There were many reports that elevated AFP levels in maternal serum and amniotic fluid have been associated with fetal distress and intrauterine fetal death, and recent studies demonstrates a high association between elevated AFP levels in maternal serum and umbilical cord blood and subsequent neonatal jaundice in normal healthy fullterm infants. To investigates the relationship between serum AFP and bilirubin levels of the newborn infants, the authors determind maternal serum and umbilical cord blood AFP concentration in 26 cases of normal healthy fullterm infants and their mothers, The serum AFP levels were measured by the method of enzyme immunoassay(AFP-EIA kit, USA) The results observed are summerized as follows: 1. The mean serum AFP levels of the newborn infants and their mothers were 27227.285ng/㎖ and 161.09ng/㎖, respectively and there was significant correlation between serum AFP levels of the newborn infants and their mothers, (Y= 14.598x+25646.955, r=0.1627, P<0.1627, p<0.005) 2. The mean serum AFP levels of the mothers and mean serum bilinibin levels of the newborn infants were 161.09ng/㎖ and 1.19ng/㎖, respectively and there was significant correlation between serum APP levels of the mothers and serum bilirubin levels of the newborn infants (Y=0.000032x+0.2831, r=0. 272491, P<0.005)

Objective : In view of the facts that education about diseases and realization of the need form drugs can improve compliance of the patients, we assessed the knowledge about drugs and medication compliance in psychiatric outpatients. In addition, we investigated factors that influence patients compliance to develop a model of medication compliance. Methods : One-hundred twelve male and eighty female psychiatric outpatient were asked about drug information using questionnaires. We developed a model that predicts medication compliance using chi square tests and multiple regression analysis. Results : More than a half of the patients knew at least one of the names and the effects of the drugs they had taken, but many of them didn't know the side effects of drugs. About eighty percent of the patients showed good compliance. Knowledge of side effects, belief in the benefits of drugs, and level of education could predict medication compliance reliably. Conclusions : Because education level could not be managed by physician, we could enhance compliance through education about drug side effects and benefits of medications.

This study was carried out to identify lactic acid bacteria in Mul-Kimchi and Dongchimi using by 16S rRNA and 16S-23S gene sequence analysis. Diluted Mul-Kimchi and Dongchimi soup were plated on the MRS agar media and colonies obtained were used for 16S rRNA and 16S-23S rRNA gene sequence analysis. Genomic DNAs were extracted from the isolated lactic acid bacteria and used as a template for PCR amplification. Universal primer sets based on the 16S rRNA and 16S-23S intergenic spacer region genes were used for amplification. From the sequencing of PCR products, Weissella kimchii, Weissella cibaria, Leuconostoc lactis, Leuconostoc citreum and Leuconostoc garlicum were identified.
