Purpose: The purposes of the present study were to review published studies that investigated arthroscopic meniscus repair to treat meniscus injury in young patients and to compare all­inside and inside­out suture techniques.Methods: Various electronic databases were queried for published articles, and this search was updated in August 2017 for evaluating the outcomes of arthroscopic meniscus surgery in young patients. Data search, extraction, analysis, and quality assessment were performed according to the Cochrane Collaboration guidelines, and the clinical outcomes were evaluated using various outcome values in young patients according to suture techniques.Results: Three randomized controlled trials and three prospective comparative studies were included in this systematic review and meta­analysis. There were no significant differences in clinical outcomes such as meniscus healing rate (risk ratio [RR], 1.11; 95% confidence interval [CI], 0.90 to 1.37; I2=39%) and perioperative complications (RR, 0.62; 95% CI, 0.23 to 1.72; I2=43%) between all­inside and inside­out techniques for meniscus repair.Conclusions: The present study shows favorable results for clinical outcomes such as meniscus healing rate and perioperative complications in young patients. Furthermore, based on our results, both all­inside and inside­out meniscal suture techniques are equally effective in these patients.

The genus Nola (Nolidae, Nolinae) was established by Leach (1815), with the Noctua palliola Denis & Schiffermüller, 1775 (a junior subjective synonym of Phalaena cucullatella Linnaeus, 1758) from Vienna, Austria. Nola comprises over 200 species: Africa and western Palearctic approximately described 100 speices (Hacker et al., 2012); Oriental and Eastern Palearctic regions have over 100 species (László et al., 2010; Sasaki et al., 2011; Kononenko and Pinratana, 2013). Two species of the genus Nola Leach; Nola euryzonata (Hampson, 1900) and Nola lucidalis (Walker, 1865), reported for the first time in Laos. Illustrations of adults and genitalia of all the examined species are provided.

본 연구에서는 비응축성 기체(공기)가 존재할 때, 10 mm의 직경을 갖는 수직 튜브 외벽에서의 응축 열전달계수를 측정하였다. 압력 2~5 bar, 공기 질량분율 10~75 %의 범위에서 실험을 수행하였다. 응축튜브 직경의 차이가 열전달계수에 미치는 영향을 평가하기 위해 측정 결과를 외경 40 mm의 응축튜브로부터 얻은 Lee의 실험 결과와 비교하였다. 본 연구의 측정결과와 Lee, 그리고 Dehbi의 실험결과를 이용하여 전열관의 직경에 의한 영향을 고려할 수 있는 실험적 상관식을 제안하였다. 제안된 상관식의 검증을 위해 Kawakubo의 실험결과와 예측값을 비교하였고, 평균 표준편차는 약 27 %로 나타났다. In this study, condensation heat transfer coefficients are measured in the presence of noncondensable gas (i.e., air) on a vertical tube with a 10-mm outer diameter. Experiments are conducted at pressures ranging from 2 to 5 bar and an air-mass fraction from 10 to 75 %. The experimental results are compared to the heat transfer coefficients obtained on a 40-mm O.D. tube, researched by Lee et al. Using the consolidated data from this study and Lee"s and Dehbi"s tests, a new empirical correlation for the condensation heat transfer coefficient of an air-steam mixture is developed. The proposed correlation is assessed against Kawakubo"s experimental results, and the mean standard deviation is ~27 %.

A successful therapy of community-acquired pneumonia requires appropriate empirical antimicrobial therapy. Etiology and antimicrobial susceptibility of major pathogens of pneumonia can differ by country. Therefore, an ideal treatment guideline of community-acquired pneumonia should be based on the studies performed in each country. We developed a treatment guideline for community-acquired pneumonia in immunocompetent adults in Korea. This guideline was developed by the joint committee of the Korean Society for Chemotherapy, the Korean Society of Infectious Diseases, and the Korean Academy of Tuberculosis and Respiratory diseases.

李金永,呂邑東 全北大學校 1981 論文集 Vol.23 No.-

韓國人類集團의 PTC (phenylthiocarbamide) 味覺에 대한 頻度의 平均値와 味盲과 血液型과의 關係를 糾明하기 위하여 그 一環으로 嶺東地方에 있어서 男女 中高等學校 學生을 對象으로 調査하여 다음과 같은 結果를 얻었다. 1. PTC 味覺은 크게 taster와 non-taster(味盲)로 區分된다. 그 中 taster는 쓴맛, 신맛, 단맛, 기타의 맛 頻度順으로 나타났다. PTC 濃度 C_1(1,300.00 ㎎/ℓ)에서 味盲의 頻度는 9.9%이었고 期待와는 달리 C_10에서는 훨씬 낮은 頻度를 나타내었다(61.2%). 쓴맛과 味盲의 頻度曲綠은 C_6과 C_7 사이에서 交叉되었다. C_13 以上의 低濃度에서의 味盲의 頻度는 거의 一定한 頻度의 傾向을 나타내었다. 2. 신맛, 단맛, 기타의 맛의 頻度는 PTC 濃度에 關係없이 男子가 女子보다 더 높았다. 특히, C_1에서의 味盲의 頻度는 男子가 9.6%, 女子가 10.6%를 나타내었고 高濃度(C_1~C_5)에서는 女子가 男子보다 PTC 味覺에 더 銳敏함을 나타내는 반면에 低濃度(C_6~C_17)에서는 그 反對現象이였다. 3. C_1에서의 血液型 A型의 味盲頻度는 11.8%, O型이 9.8%, AB型이 9.6%, B型이 8.5%였다. 이와 같이 이러한 頻度는 PTC 濃度가 낮아짐에 따라 거의 一定한 頻度의 傾向을 나타내었다. To investigate the frequency of PTC (phenylthiocarbamide) non-taster and relationship between non-taster and blood type, middle and high school students in Yeongdong population of Gangwondo province, Korea were studied. The results are as follows : 1. Most of the tasters tasted PTC as bitter. However some tasted as sour, sweet and other in the order of frequency. Frequency of non-taster of C_1 was 9.9%. That of C_10 was unexpectedly low (61.2%). The curves of bitter and non-taster was crossed between C_6 and C_7. the In lower concentrations than C_13, the frequencies of non-taster were inconsistent. 2. The frequencies of sour, sweet and other taster in male were higher than in female. Especially, the frequency of non-taster of C_1 was 9.6% in male and 10.6% in female. Whereas male was more sensitive to the high concentrations(C_1~C_5) of PTC, female was more sensitive to the lower concentrations(C_6~C17). 3. Among the non-taster of C_1, the frequency of blood type A was 11.8%, O 9.8%, AB 9.6%, and B 8.5%. This frequencies invariably changed as the PTC concentration become lower.

A self-piercing rivet(SPR) is a mechanical component for joining dissimilar materials. It is used for joining dissimilar material sheets such as aluminum alloy and steel. The self-piercing rivet directly pierces into sheets without drilling sheets beforehand unlike conventional rivets. However, the self-piercing rivet occurs buckling when piercing high strength steel. Therefore, a helical SPR which can pierce high strength steel sheet was designed. In this study, forging process was designed for manufacturing the helical SPR and simulated by using commercial FEM code DEFORM-3D. In the simulation of forging process for manufacturing rivet, process sequence, formability, forging load were investigated. The suitable forging process could be designed by comparisons of simulated results. Experimental trials have been carried out for same conditions as simulated ones. The simulated results agreed with the experimental ones. So, the analytic approach in this thesis is useful to save cost and time in the forging industry

이중림,최동훈,김해영 경희대학교 생명자원과학연구원 1997 硏究論文集 Vol.18 No.-

Translation 과정에 영향을 미치는 RNA의 이차 구조와 구조의 존재하는 위치에 대한 영향을 조사하기 위해 본 연구에서는 model system으로 사람의 ferritin 유전자를 이용하였다. Ferritin 유전자의 5‘UTR, 단백질의 coding 지역내, 3’ UTR 등 3가지 위치에서 변형된 이차구조 인자를 이용하여 ferritin 단백질의 생성량을 in vitro translation을 이용하여 비교 측정하였다. 이 가운데 5‘ UTR에 존재하는 RNA 이차구조만이 ferritin 합성을 저해하였다. Genetic controls of cell metabolism and differentiation involve translational regulatory mechanism. Iron-responsive elements located within 5' or 3' untranslated regions(UTRs) are utilized for translational specific mRNAs. To identify the locations of structural elements utilized for translational regulation of mRNA, we modified and tested the roles of structural elements located within the 5', 3' UTR or coding region of ferritin. Our data suggest only 5'UTR element within ferritin is important for translational regulation.

This study is a base research on which the Seoul National University of Education implements the subject of 'Social Service Activities' as part of the formal curriculum. The purpose of this study was to suggest a systematic program for the curriculum implementation. The major research methods of this study were the analysis of precedent literature regarding Social Service Actities, and the interview method. As the research results, this study presents the discussion products regarding the concept·characteristics·contents of social service activites, the present situation of service activites in Korea and other countries, the preparation/attitude of university students who are going to practise those activites. As far as the concrete curriculum implementation is concerned, this study suggests twofold specific ideas. First, this study presents ideas on the curriculum form such as regarding in which semeter the subject is open, how students apply for the subjects, how to designate advising professors, what is the role of the professors, how to evaluate the activity results of students, and how to select the relevant institutions in which the activities are carried out. Second, this study suggests to construct an curriculum implementation committee and to make a implementaion guide. The committee is supposed to carry out manage/control the social service curriculum, and consider important matters on the curriculum impletation.
