고민균(Min-Gyun Ko),전영주(Young-Ju Jeun) 한국컴퓨터정보학회 2020 韓國컴퓨터情報學會論文誌 Vol.25 No.1

본 연구는 의료기관 사무직 종사자들의 근 경직도에 대한 스트레칭의 효과를 알아보려고 한다. 총 40명의 젊은 여성 대상자들이 자발적으로 이 연구에 참여했다. 대상자들은 스트레칭 군과 대조군에 무작위로 분류하였다. 스트레칭 중재 전, 대상자의 흉쇄유돌근, 상부승모근, 후두하근, 소흉근의 근 경직도를 측정하였다. 그리고 스트레칭을 스트레칭 군에 적용하였다.중재 후 5분이 지나서 각 근육의 근경직도를 재측정하였다. 스트레칭 군에서 흉쇄유돌근, 상부승모근, 후두하근, 소흉근의 근 경직도는 유의하게 감소하였으며(p<.05), 대조군에서는 중재 전과 후에 유의한 차이가 나타나지 않았다. 따라서 적절한 스트레칭은 의료기관 사무직 종사자의 근 경직도의 증가로 인해 야기될 수 있는 근골격계 질환을 예방하고 감소시킬 것으로 사료된다. This study is to investigate the effects of stretching of hospital office employees on muscle stiffness. A total of 40 healthy young women voluntarily participated in the study. The participants were randomized to the stretching groups and control groups. Before stretching, the participants measured muscle stiffness of sternocleidomastoid muscle, upper trapezius muscle suboccipital muscles and pectoralis minor. And then applied stretching to stretching group. Muscle stiffness remeasured five minutes later in each group. In all muscles, muscle stiffness of stretching group were significant decreased(p<.05), but control group were no significant difference between pre and post. therefore appropriate stretching is expected to prevent and reduce musculoskeletal diseases caused by increased muscle stiffness in hospital office employees.

벼꽃으로부터 calmodulin 유전자의 분리 및 염기서열분석

고명수,최영주 신라대학교 자연과학연구소 2003 自然科學論文集 Vol.12 No.-

Calmodulin (CaM) plays an important role in sensing and transducing changes in cellular Ca2+concentration in response to several biotic and abiotic stresses. Two cDNA clones encoding two different calmodulin, RFCaM-1, and RFCaM-2, were isolated from a rice flower cDNA library and their nucleotide sequences were analyzed. Comparison of the deduced amino acid sequence of the RFCaMs cDNA clone have identity to Arabidopsis (70%), potato (92%), carrot (98%), and barley and soybean (98%). In order to determine the copy number and genomic structure of the CaM genes present in the rice genome, a genomic Southern blot analysis was performed using a rice calmodulin cDNA clone (RCaM-2) as a probe. Four intense and a few weaker bands were observed in the restriction fragments. Most restriction fragments showed high intensity hybridization signals under stringent conditions, suggesting the presence of a small multigene family for CaM in the rice genome as in other plants.

The present study was conducted in three fields at Namhae to examine the removal efficiency of organic free, heavy metal immobilized sediment on Cochlodinium polykrikoidesand on sea water quality. The present study results concluded that removal efficiency was depends on the initial number of red tide cells. There was no drastic change in the sea water quality after sediment spray. For the comparison of effectiveness of betonite, zeolite and lime were mixed with sediment did not show any marked difference in removal. Finally, the present study evaluated 5Og/m² sediment is Sufficient to remove 100% cells density, even though various environmental factors are interfering the mechanism.

Ca^(2+)은 신호전달과정에서 중요한 작용을 하는데 CaM은 이러한 Ca^(2+)이은의 modulator로서 중요한 작용을 하는 것으로 알러져 있다. 벼꽃의 cDNA library로부터 rice genomic DNA(RCaM-2)를 probe로 사용하여 30여개의 Positive clones을 얻어 이 중 두 개의 벼꽃 calmodulin CDNA clone을 분리하였다. RFCaMs CDNA clone의 총염기수는 RFCaM-3은 831p, RFCaM-4는 751bp이고 open reading frame은 각각 149개의 아미노산으로 구성되어 있다. RFCaM-3 과 RFCaM-4의아미노산은 동일하지만 nucleotide 순서는 상당한 차이를 나타내고 있다. RFCaMs CDNA clone의 open reading flame은 protein serine/threonine kinase에 보존되어 있는 catalytic domain을 가지고 있다 RfCaM-3은 5'-untranslated region은 105bp, 3'-untranslated region은 270bp이고 RfCaM-4는 5'-untranslated region은 78bp, 3'-untranslatedregion은 283bp이다. RFCaMs는 Arabidopsis와 70%, potato와는 92%, carrot과는 98%의 유사성을 보였다. Genomic southern blot분석에 의하면 벼의 clamodulin 유전자들이 7-8개의 multigene family로 존재하는 것으로 나타났다. Two different calmodulin (CaM) cDNAs (RFCaM-3 and RFCaM-4) were isolated from a rice flower cDNA library by screening with a rice genomic probe (RCaM-2). Both cDNAs are 90% sequence homologous inside the coding region but are highly divergent outside this region. The polypeptides encoded by RFCaM-3 and RFCaM-4 show identical sequence homology. Comparison of the deduced amino acid sequence of the RFCaMs cDNA clone have identity to Arabidopsis (70%), potato (92%), carrot (98%), and barley and soybean (98%). Southern analysis revealed that both cDNAs are encoded by different genes. Four intense and a few weaker bands were observed in the restriction fragments. Most restriction fragments showed high intensity hybridization signals under stringent conditions, suggesting the presence of a small multigene family for CaM in the rice genome as in other plants.

전통발효식품으로부터 Chitin 분해 미생물의 분리 및 특성 규명

고보경,최인순,이상현,임채오,이성호,갈상완,최영주 Plant molecular biology and biotechnology research 2004 Plant molecular biology and biotechnology research Vol.2004 No.-

A bacterial strain CJ-3 which produced chitinase was isolated from Korean traditional soy sauce. Using 16S rDNA analysis, the strain CJ-3 was identified as Bacillus atrophaeus. The approximate molecular weight of the putative chitinase enzyme was 31.0 kDa and the enzyme activity was remarkably induced by addition of colloidal chitin (0.5, 1.0, 2.0%). The antioxidant activity was increased 53% by the browning reaction products of B. atrophaeus CJ-3. Escherichia. coli lipopolysaccharides (LPS)-induced production of nitric oxide (NO) was reduced up to 45% by the browning reaction product in RAW264.7 macrophage. Inhibition of cell viability in the presence of LPS was recovered to normal level by the browning reaction product. These results suggest that browning reaction of B. atrophaeus CJ-3 plays an important role for activation of immune system. B. atrophaeus CJ-3 exhibited optimum temperature and pH of 37℃ and pH 7.8~8.0, respectively. The major intracelluar free amino acid was determined to be glutamate.

과거 소아치과 치료의 경향은 충치 및 발치 등의 주소에 따른 치료 중심이었지만 최근 출생률 감소, 우식 유병율 감소, 보호자의 치과적 지식의 증가에 따라 그 양상이 변화하고 있다. 이러한 변화양상을 파악하고 앞으로 전북 지역 어린이 환자 치료의 방향을 설정하고자 본 조사를 시행하였다. 1998년 1월 1일부터 2005년 12월 31일까지 전북대학교치과병원 소아치과에 내원한 모든 초진환자를 대상으로 분포를 연구한 결과 다음과 같은 결론을 얻었다. 1. 초진환자의 수는 2004년까지 증가하다가 2005년에는 감소하였으며, 남아가 여아보다 많았다. 2. 방학기간에 초친환자의 수가 증가하였다. 3. 내원 환아의 97.7%가 도내 거주자였다. 4. 연령별 분포에서 31개월~6세 군이 48.2%로 가장 높게 나타났으며, 7~13세 군이 31.3%, 13~30개월 군이 17.2%였다. 5. 의뢰되어 내원한 환자가 33.8%였으며, 의뢰된 환자 중 31개월~6세 군이 49.5%로 가장 많았고, 7~13세 군이 35.2%, 13~30세 군이 12.9%를 나타냈다. 6. 전신질환을 가진 환자는 전체의 5.5%를 차지했으며, 이 중 심혈관질환이 21.8%로 가장 높은 비율을 보였고, 정신지체가 13.6%, 호흡기질환이 11.0%순 이었다. 7. 내원환자들은 치아우식증을 주소로 내원한 경우가 42.9%로 가장 많았다. 8. 치수치료, 수복, 보철 치료가 전체 치료의 42.6%로 가장 많았다. In order to thoroughly understand change patterns and to set up an appropriate approach on the direction of future treatment towards children in Chonbuk area, we carried out this research. we could draw below conclusions from the studies based on researches of distribution of new patients visited Dept. of Pediatric Dentistry, Chonbuk Nat' university from 1998 to 2005 and current changes in dental treatment. 1. There was an increase in the number of patients until 2004 but it decreased in 2005. Boys took higher portion. 2. Number of patients increased during school holidays. 3. 97.7% of patients were urbanites. 4. An age group from 31 months to 6 years showing 48.2% was the highest, each percentage of 7~13 years, 13~30 months showed 31.3%, 17.2%. 5. 33.8% of patients were referred from local dental clinics and among them, an age group from 31 months to 6 years showing 49.5% was the highest, each percentage of 7~13 years, 13~30 months showed 35.2%, 12.9%. 6. 5.5% of patients who had systemic diseases, among them, each percentage of cardiovascular disease, mental retardation, respiratory disease showed 21.8%, 13.6%, and 11.0%. 7.
