치아에 외상을 받은 경우 치수 생활력의 상실은 흔한 일이다. 치수 생활력을 검사하는 방법으로는 임상적, 방사선학적으로 여러 가지가 있지만, 미성숙 외상치의 경우 일시적 현상과 가성 반응이 나타날 수 있으므로 치수 괴사에 대한 정확한 진단은 매우 어렵다. 생활력을 상실한 치아는 염증성 치근흡수, 치근단 낭종 등의 발생을 방지하기 위하여 치수 치료를 시행한다. 그러나 미성숙 영구치의 경우, 치수 치료를 시행 후 치근 성장이 정지될 수 있어 결과적으로 얇고 짧은 치근이 형성되어 장기적인 예후는 좋지 않다. 본 임상 증례에서는 외상으로 인하여 실활된 초기 영구치에서 치근단부의 최소한의 침습적 치근단 형성술로 계속된 치근 형성을 보여 이에 보고하는 바이다. In case of luxation injuries, loss of tooth vitality is common. And in case of trauma in the immature permanent teeth, precise diagnosis of pulp necrosis is very difficult. That is because limitation in distinguishing between normal dental papilla in immature permanent teeth, transient apical breakdown(TAB), which is part of normal healing process, and apical radiolucency in pulp necrosis. Especially in non-vital immature permanent tooth, the treatment is complex and requires long time. This clinical case report shows that severely infected immature teeth with periradicular periodontitis can undergo healing and apexogenesis or maturogenesis with no definative treatment or after conservative treatment. In the cases reported, we emphasize the considerable power of regeneration of the tooth, probably due to its large number of undifferentiated mesenchymal cells in the dental papilla, pulp tissue, periodontal ligament tissues. Thus, when endodontic treatment in immature permanent teeth, over instrumentation is not recommend for preserve the apical vital stem cells.

단감 수학과에 잔존하는 절지동물의 제거기술 평가

강창훈,이상명,허혜순,박정규 경상대학교 농업생명과학연구원 2002 농업생명과학연구 Vol.36 No.4

우리나라 단감의 수출선을 다변화하기 위해서는 검역문제를 해결하여야 한다. 본 연구는 이러한 문제를 해결하기 위하여 단감 수확과에 잔존하는 해충의 제거방법으로 고온처리와 air shower 처리의 효과를 실험하였다. 점박이응애를 단감(부유)에 접종하고 50℃에서 4시간 처리하면 99.4%의 치사효과를 얻을 수 있었지만, 45℃에서 3시간이나 50℃에서 1시간 이상 처리하였을 때 감이 연화되는 현상이 나타났다. 단감의 수확과에 존재하는 충은 톡토기류, 균식성응애, 잎응애의 3종류이었는데 균식성응애의 밀도가 가장 높았다. 꽃받침 윗면에 존재하는 충은 100% 제거할 수 있었다. 그러나 아랫면에 존재하는 충은 톡토기와 잎응애는 air shower로 100과 중에서 2마리 수준까지 제거할 수 있었지만 균식성응애는 원래 밀도가 높아서 모두 제거하는 데는 무리가 있었다. 따라서 수확과에 잔존하는 해충을 완전히 제거할 수 있는 새로운 기술의 개발이 요구된다. No quarantine pests are allowed in exporting fruits. To meet the quarantine requirement, it is essential to remove pests from harvested fruits. We tested a few methods to remove or kill the pests on persimmon fruits. The efficacies of hot-air treatment and air shower were tested on sweet persimmon. Hot air (50℃) treatment for 4 h showed 99.4% mortality of Tetranychus urtioae. However, longer than 3-h treatment at 45℃ and 1-h treatment at 50℃ caused softening of the fruits. The efficacy of air shower generated with a compressor (max W.P., 200 lbs; 10-14 sec shower/fruit) in removing the pests on persimmon fruits was tested. Collembolans, fungus-feeding mites, and leaf mites on and under the calyx lobes were the common pests on persimmon fruits. All the pests on the calyx could be removed by the air shower treatment. However the pests under the calyx were resistant to the air shower treatment. Collembolans and leaf mites could be reduced to two individuals per 100 fruits (98% removal). However, the fungus-feeding mites could not be removed by the air shower because of the high initial density of the mite and the shield by the calyx. Therefore it is evident that the air shower treatment cannot remove 100% of the pests under the calyx. Therefore development of new technology is required to remove pests from harvested persimmon fruits.

The purpose of this study was to identify whether shoulder complex exercise program with visual feedback could improve the shoulder muscular strength and postural alignment in adolescents with shoulder asymmetry. Twenty eight subjects were recruited from the K university and divided into three groups: experimental 1, 2group(Each n=10) and control group(n=8). For 4 weeks, the experimental group 1 performed shoulder muscle complex exercise program and the experimental group 2 performed shoulder complex exercise program with visual feedback. The control group did not perform exercises. The shoulder muscle strength and difference between the height of left and right shoulders were assessed before, after training using the hand-held dynamometer and Global Posture System. Subordination variables, general characteristics analysis, χ² test and Kruskal Wallis H test were conducted to evaluate differences between groups and training before, after changes were checked Wilcoxon signed rank test with using the PASW 18.0 statistical program. The results of the study were as follows. 1) Both the experimental 1, 2group showed improvements in muscle strength of several muscles following training (p<.01). The control group showed significant reduction in the left posterior deltoid (p<.05), and did not show significant changes in examining other muscles (p>.05). And there were differences among three groups in shoulder muscle strength (p<.001). Muscle strength changes in several muscles were greater in the experimental 1, 2group compared with the control group (p<.001). Muscle strength changes in the several muscles were greater in the experimental group 2 compared with the experimental group 1 (p<.001) 2) Both the experimental 1, 2group showed significant decreases in the difference between the left and right shoulder heights following training (p<.01). The control group did not show change (p>.05). Changes in the difference between the left and right shoulder heights were greater in the experimental 1, 2group compared with the control group (p<.001).

신인혜,선경희,강순철,박경린 濟州大學校 基礎科學硏究所 2003 基礎科學硏究 Vol.16 No.1

대부분의 사용자들은 자료를 저장하고 검색하기 위하여 관계형 데이터베이스를 사용하여 왔는데, 최근에 차세대 웹문서의 표준으로 주목받고 있는 XML은 데이터베이스와 같이 자료를 표현, 저장, 검색할 수 있는 기능을 가지고 있다. 본 논문에서는 임의로 생성한 검색대상 자료를 데이터베이스에 테이블로 저장하여 검색하는 방법과 XML 문서로 저장하여 검색하는 방법의 검색시간이 성능비교를 행하였다. 성능평가 결과, 검색 파일의 레코드 수가 약 1만개 이하인 경우에는 XML 문서를 이용한 검색이 빨랐고, 그 이상인 경우는 데이터베이스를 이용한 검색 시간이 월등히 빨랐다. XML 관련 검색 파일들을 세부적으로 XML 문서를 저장하는 방법(어트리뷰트로 혹은 엘리먼트)과 C#에서 XML 문서를 읽어드리는 방법(XPath을 혹은 DOM)에 따라 성능평가를 하였는데 XML 문서 작성시 어트리뷰트로 구성하고 마이크로소프트 닷넴 프레임워크에서 제공하는 XPath를 이용하여 XML 문서를 검색하는 방법이 가장 효율적이었다. While most of users have used relational databases to store and search data. XML documents also can represent, store, and search these data like database systems. This paper compares the search time of data in the XML documents with those in database systems. The performance comparison shows that the search time using the XML document is faster than that using database when the number of records is less than then thousand. However, the latter is much faster than the former when the number of records is more than ten thousand. The XML documents can be consist of either using Attributes of Elements. Also, the document can be read either using DOM or XPath. The performance comparison shows that the XML document made up of Attributes and being read using XPath in Microsoft Net Framework provides the fastest search time.

Objective: To investigate the relationship between body mass index (BMI) and liver function abnormalities in the general population in Korea. Methods: The study subjects were 5765 persons who were received questionnaire survey and health examination of national health and nutrition survey in 1998, 20-59 years in age and had no history of viral hepatitis. BMI was categorized by quartile and abnormal liver functions were defined aspartate aminotransferase (AST) >30 U/L or alanine aminotransferase (ALT) >35 U/L in serum level. In order to identify the association of BMI and abnormal liver function, chi-square test and multivariate logistic regression analysis were used. Results: The abnormality rates of AST were 35.0% in male and 13.4% in female. The abnormality rates of ALT were 35.8% in male and 11.1% in female. After controlling for the other covariates, the multivairate logistic regression analysis showed that BMI was the significant related factor of abnormal AST (male; odds ratio=1.25; 95% confidence interval=1.15-1.36, female; odds ratio=1.14; 95% confidence interval=1.02-1.26) and abnormal ALT (male; odds ratio=1.87; 95% confidence interval=1.71-2.04, female; odds ratio=1.56; 95% confidence interval=1.38-175). Conclusions: We identify that BMI was the significant risk factor of non-viral liver disease with abnormal liver functions. A large-scale investigation will be suggested in the future to demonstrate the causal-effect issue between abnormal liver function and obesity.

Apo B-100 is a constitutive component of low density lipoprotein (LDL) of which functions in packaging, transport and absorption of lipids Extortive binding of anti B_(4)-antibody onto the Apo B-100 should inhibited the functions of Apo B-100 Previously we had showed that the peptide B_(4) induced antibodies recognized Apo B-100 and thus elicited anti-obesity effect In this study we compared the efficacy of antibody inducing immune responses by introducing additional peptides fused to the C-termninal of B_(4) peptide We constructed TB_(4) hybride peptide of B_(4) with preS2 of HBV and B_(4)N another epitope orientation of chimeric TB_(4) Among these three artificial peptides B_(4)N was the most efficient inducer of the antibody against B_(4) These result explains that the B cell epitope and T-helper cell epitope orientation is very important factor to determine the antigenicity to humoral immunity. Apo B-100은 LDL에서 지방을 포장, 흡수, 운반하는 기능을 수행하는 단백질이다. Apolipoprotein B-100(Apo B-100)에 대한 특이 항체의 결합은 LDL의 정상 기능을 방해한다. 선행 실험에서 Apo B-100의 모조 펩타이드인 B_(4)가 Apo-B-100을 교차 인식하는 항체를 유도하고, 비만 억제 효과를 나타내는 것으로 밝혀졌다. 본 연구에서 B_(4)펩타이드의 C-terminal부분에 펩타이드를 융합, 첨가하므로 면역반응에서 항체유도의 면역응답반응에 어떠한 효과를 나타내는지 비교해 보고자 하였다. B_(4)펩타이드의 N-말단에 HBV의preS2 펩티드를 융합시킨 B_(4)T의 N-말단데 또다른 B세포 에피도프 펩티드를 융합시킨 B_(4)N을 작성하였다, 세종류의 하이브리드 펩타이드 중에서 B_(4)N이 B_(4)에 대한 항체유도능이 가장 효율적이다,. 이상의 결과로 B cell epitope과 T-helper cell epitope의 방향성이 체액성 면역 반응에서 항원유도능을 결정하는 중요한 요소임을 확인하였다.
