문지영,김정원 한국의류산업학회 2004 한국의류산업학회지 Vol.6 No.6

The social culture critics say that the current situation of the boom in pretty men happened because stereotyped notions of sex roles have changed. However, no scientific study has been done as yet to support this theory. Therefore, this study analyzed the present situation and examined it from many different points of view. I asked 600 men to fill out the questionnaire: 300 from Daegu and the other 300 from Seoul. I analyzed four 461 of them. The inner/outer image of Korean males in their 20s was analyzed into seven factors, a positive image, a progressive image, an affirmative image, a sensible image, an exemplary image, a conscious image, and an active image. The demographic result based on the inner/outer image factors showed a significant difference in ages for a sensible image, a conscious image, and an active image.

객체지향 개념 모델링에서 OCL에 의한 상속성 원리

이지연,최병문,이영환 대전대학교 기초과학연구소 2003 自然科學 Vol.14 No.1

OOA/D에서는 클래스의 일반화와 특수화의 계층구조 사이에서 상속성의 개념이 어디까지 보장되는지 명확한 규칙이 없다. 예를 들어 상위 클래스의 제약조건이 하위 클래스에도 상속되는지, 상위 클래스의 상태 다이어그램이 하위 클래스의 상태 다이어그램에도 상속되는지, 하위 클래스의 행위는 상위 클래스의 행위를 제한시키는 것인지 확장시키는 것인지 등의 문제가 명확하지 않다. 또한 역할과 하위 클래스 설정 문제도 혼동이 일어난다. 본 논문에서는 Liskov의 치환 규칙에 의하여 정적인 면과 동적인 면을 동시에 고려한 상속성 원리를 OCL을 사용하여 정립한다. 이에 따라 역할, 일반화, 특수화, 집합체와 합성에 관한 개념의 가이드라인도 제시한다. There are no explicit rules in OOA/D to indicate whether or not the generalization and specialization hierarchy on a superclass is inherited by its subclasses. For example, we have relevant questions: ls a constraint on a suerclass is inherited by its subclasses? Does subclasses inherit the state diagram of the superclass? Can it refine this state diagram by adding. removing or redefining states, transitions, or events? Can it restrict the behavior of the generalization classes or extend it both? Many methods do not answer these questions. Also concepts of role and subclass are confused in the problem of structure. In this paper, we give an OCL formalization of inheritance by Liskov's Substitution Principle and propose a general guide-lines of concepts of role, generalization, specialization, aggregation, and composition.

In Korea, EMT have two classified subgroup of first and second degree : EMT-P, and EMT. For the beginning, authorization of the first EMT was made in this year through the EMT educational program. There are 8 items which EMT can perform the treatment without the supervision by a physician. But there was no previous report of pertinent assesment of treatment performed by the EMT. There upon authors have conducted review of assessment done by the EMT in EC setting, and proposed the following treatment application can be used by EMT at the field of accident. The study materials include adult trauma patient older than 15 years, and sustained trauma within 48 hours before visiting Ewha University DongDaeMoon Hospital Emergency Deparment. The duration of study was from Apr. 1 1995 to Aug. 31 1995. the study was conducted by 5 certified EMT. The EMT's performance was evaluated by the attending Emergency Medicine physician. The result were as followings ; 1. Among the total 5532 ED visiting patients during the study period, 1267 were adult trauma patients who recieved treatment within 48 hours of injury. 2. Among 1222 out of 1267 patients have completed performed survey. 3. Male to female ratio was 2.6 : 1, age distribution was from 15 to 87 years old and mean age was 34.6 years old. 4. The MOI showed : MVA (33.1%), blunt trauma (29.9%), slip down (16.8%), penetrating injury(15.4%), and miscellaneous (5.7 %), burn (3.1%), falling down injury(2.9 %), bite injury(1.1%) in order. 5. There were 437 cases of survey completed by the EMT. For assessment of mental status of 3 different method : AVPU, 5 scale mental status and GCS, were correlated with EM physician with 99.1%, 98.6%, 97.7 %, respectively. 6. For 320 out of 437 cases of survey completed, 319 patients recieved treatment by the EMT within 30 minute and 1 patient between 30 to 60 minute of an ED arrival. 7. For those 437 cases of survey completed, 266 patient (60.9%) had adequate treatment and 54 patients (12.4%) had inadequate treatment. 67 patient (15.3%) did not received treatment but it was adequate inway, and 50 patients (11.9%) did not received treatment even though patient required treatment. In cases of adult trauma patients, EMT's mental status assessment was correlated with EM physician's assessment. But treatment done by EMT without the supervision of EM physician was adequate only in 76.2 %. Therefore, continuous education and assessment of treatment performed by EMT in needed to improve field treatment by EMT future.

노홍균,김지숙,이문이,조영인 대구효성가톨릭대학교 식품과학연구소 1994 식품과학지 Vol.6 No.-

여러 pH 조건 및 키토산 농도하에서 쌀세척 폐수로부터 부유성 고형물을 효과적으로 응집, 회수할 수 있는 방법을 모색하였다. 키토산 첨가에 따른 탁도감소효과는 pH가 낮아짐에 따라 작았으며 pH 6 이상에서는 키토산 농도가 증가함에 따라 현저히 컸다. 그러나, 폐수의 탁도감소는 키토산 농도와는 관계없이 pH 4일 때 가장 효과적 이었으며 pH가 증가함에 따라 저하하였다. 쌀세척 폐수내의 부유성 고형물은 폐수의 pH를 4로 조정한 후 원심분리하므로서 가장 효과적으로 침전, 회수할 수 있었다. 이 때 탁도감소는 99% 이상을 나타내었으며, 폐수내 부유물질의 농도차와 pH 조정제로 사용된 산종류는 탁도감소에 영향을 미치지 않았다. 폐수의 탁도감소 효과는 저장기간이 길어짐에 따라 저하하였다. Treatment of rice-washing wastewater was considered under various pH levels and chitosan concentrations. Compared with the control test, addition of chitosan at the various concentrations did not noticeably enhanced turbidity reduction at pH 4 and 5, but greatly enhanced at above pH 6. However, reduction of turbidity in the wastewater, irrespective of chitosan concentrations, was the greatest at pH 4 and became lower by increasing pH. Suspended solids in the wastewater were the most effectively recovered by pH adjustment of the wastewater to 4 followed by centrifugation, with over 99% reduction in turbidity. Different concentrations of suspended solids in the wastewater and various kinds of acids used for pH adjustment did not affect turbidity reduction. Increasing storage periods of the wastewater resulted in lower reductions in turbidity.

Fluorescent probes of Aspergillus oryzae lectin fused with fluorescent proteins are internalized into golgi via endocytosis

The a(1,6)-fucose attached to the core N-glycan (core fucose) of glycoproteins has been known to play essential roles in various pathophysiological events, including oncogenesis and metastasis. Aspergillus oryzae lectin (AOL) encoded by the fleA gene has been reported to bind to N-glycans containing this core fucose. In our previous study, the fleA gene was fused with genes of fluorescent proteins to generate fluorescent probes. Their binding capabilities to core fucose was confirmed by lectin blot and cytochemical staining. Here, we describe the internalization properties of the FleA-fluorescent fusion proteins. During cell imaging experiments, we surprisingly found that these proteins could be internalized into intracellular compartments, especially Golgi apparatus, when applied to live cells. In contrast, their fluorescences were observed only on the cell surface when applied to the fixed cells or the metabolically arrested cells at low temperature. These results suggested that FleA-fluorescent fusion proteins first bound to the core-fucosylated glycoprotein located on the cell surface and then could be internalized by the active cellular process. This internalization was shown to occur depending on a clathrin-mediated pathway by endocytosis inhibitor assay. Taken together, FleA-fluorescent fusion proteins can be employed as a vesicle for delivery of useful materials to the inside of cells as well as a valuable fluorescent probe for detection of core fucose.

Glyco-engineering of Recombinant Expression Systems for Production of Biobetter

Ji-Yeon Kang,Jin Young Gil,Se-Jong Lim,Yeong Hun Kim,Ji-Young Mun,Keun Koo Shin,Doo-Byoung Oh 한국당과학회 2016 한국당과학회 학술대회 Vol.2016 No.07

More than 60% of the currently available therapeutic proteins are glycoproteins attached with glycans, which play important roles in the protein folding, therapeutic efficacy, in vivo half-life, and immune reactions. Our group has focused on N-glycosylation pathway engineering of recombinant expression hosts including yeasts and Chinese hamster ovary (CHO) cells for production of therapeutic glycoproteins with improved potency. Different engineering strategies are required depending on the classes of therapeutic proteins because their optimal glycan structures are different. Many therapeutic enzymes used for treatment of lysosomal storage diseases require high contents of mannose-6- phosphate (M-6-P) glycan, which is essential for cellular uptake and targeting to lysosomes. Although yeasts do not have M-6-P glycans, they have some glycans containing mannosylphosphorylated mannose residues which can be converted to M-6-P structure through removal of the outer capping mannose. Recently, we constructed a glyco-engineered Saccharomyces cerevisiae mnn1Δoch1Δ strain overexpressing YlMPO1 gene, which was shown to have very high content of mannosylphosphorylated glycans [1, 2]. As they were efficiently converted to high content of M-6-P glycans through uncapping process, our engineering strategy showed a promise for production of biobetter enzymes with enhanced lysosomal targeting capabilities. For prolonged in vivo half-life of glycoproteins, sialic acids present on non-reducing terminal of glycan are important. We compared several bacterial α(2,6)-sialyltransferases and found that they have inherent siallidase activities, which decreased the amount of sialylated products [3]. These sialidase activities were inhibited by simple treatment of alkaline phosphatase, which desphosphorylates free cytidine monophosphate (CMP) generated from a donor substrate (CMP-N-acetylneuraminic acid) during the sialyltransferase reaction. It greatly enhanced the efficiency of bacterial α(2,6)- sialyltransferase reaction, which resulted in the increased content of bi-sialylated N-glycan up to ~98% without any decrease in prolonged reactions. Our efforts to construct Chinese hamster ovary (CHO) cells for production of glycoproteins with increased content of sialic acids shall be introduced also.

( Ji Young Bae ),( Do Young Choi ),( Chul Ho Woo ),( In Suk Kwak ),( Sung Ha Mun ),( Kwang Min Kim ) 대한마취과학회 2011 Korean Journal of Anesthesiology Vol.60 No.3

Background: Many pathophysiologic alterations in patients with major burns can cause changes in the response of propofol. The aim of this study is to determine the appropriate induction dose of propofol using a slow infusion rate for major burn patients to obtain desirable sedation and hypnotic conditions with minimal hemodynamic changes. Methods: 45 adults with major burns and who were electively scheduled for escharectomy less than a week after injury were recruited. For induction with propofol, the patients were randomly allocated to one of two groups (group 1: 1.5 mg/kg, n = 20 and group 2: 2.0 mg/kg, n = 25). The infusion rate was 20 mg/kg/hr. The systolic and diastolic blood pressure (SBP, DBP), the heart rate, the bispectral index and the modified observers` assessment of the alertness/sedation scale (OAA/S) were measured before the induction and after the propofol infusion, as well as immediately, 3 and 5 minutes after intubation. Results: The SBP and DBP were significantly decreased after the propofol infusion in both group, but there were no significant differences between the two groups. The BIS values after the propofol infusion and intubation were 44.2 ± 16.1 and 43.5 ± 13.8 in group 1, and 45.6 ± 10.3 and 46.5 ± 11.4 in group 2, respectively, and there were no differences between the 2 groups. Conclusions: When propofol is administrated to major burn patients, an induction dose of 1.5 mg/kg is appropriate and a slow infusion rate of 20 mg/kg/hr is safe for maintaining the desired hypnotic conditions and this dose and rate cause no significant hemodynamic problems.
