        정문미(Jung, Moon Mi),원영신(Won, Young Shin),고대선(Ko, Dae Sun) 한국노년학회 2010 한국노년학 Vol.30 No.2

        본 연구는 여성 연소노인의 사회 인구학적 특성에 따른 지각연령의 차이를 알아보고 지각연령이 사회무용 지도자 선호에 미치는 영향을 규명하는 데 목적이 있다. 이와 같은 연구목적을 달성하기 위하여 서울지역 소재 노인교육기관(노인교실, 노인대학, 노인학교, 노인복지회관, 사회복지회관, 대학부설 평생교육원 및 사회교육원, 종교기관 등)에서 사회무용 프로그램에 참여한 경험이 있는 여성 연소노인을 모집단으로 설정한 다음, 유의표본표집법을 이용하여 450명의 연구대상을 표집하였으며, 불성실하게 응답한 자료를 제외하고 총 428명의 자료를 최종분석에 사용하였다. 자료처리는 SPSS Windows 15.0 version을 이용하여 빈도분석, 탐색적 요인분석, 신뢰도분석, 카이검정, 독립표본 t-test, 일원분산분석, 이항 로지스틱 회귀분석을 실시하였으며, 다음과 같은 결론을 도출하였다. 첫째, 사회 인구학적 특성에 따른 지각연령은 역연령, 교육수준에 있어서 지각연령 하위요인(보이는 연령, 느끼는 연령, 관심사 연령, 활동 연령) 모두에 유의한 차이가 나타났다. 또한 결혼유지 상태는 관심사 연령과 느끼는 연령, 경제수준은 보이는 연령, 관심사 연령, 느끼는 연령에 있어서만 유의한 차이가 나타났다. 둘째, 사회 인구학적 특성에 따른 사회무용 지도자 선호는 교육수준에 있어서 사회무용 지도자 선호 하위특성(성별, 연령, 교육수준, 전공경력) 모두에 유의한 차이가 나타났다. 또한 역연령은 지도자의 전공경력을 제외, 경제수준은 지도자의 성별을 제외한 모든 사회무용 지도자 선호 하위특성에 유의한 차이가 나타났으며, 결혼유지 상태는 지도자의 교육수준에 있어서만 유의한 차이가 나타났다. 셋째, 지각연령이 사회무용 지도자 선호에 미치는 영향을 분석한 결과, 지각연령의 하위 요소 중 보이는 연령만이, 사회무용 지도자 선호하위특성 중 전공경력을 제외한 성별(B=.458), 연령(B=.483), 교육수준(B=.76) 모두에 유의한 정적(+) 영향을 미치는 것으로 나타났다. The purpose of this study was to examine the demographic characteristics of the female young-old to their self-perceived age and the impact of their self-perceived age on preference for a social dance instructor. The subjects in this study were 450 women who were selected by purposive sampling from a population of the female young-old who had ever participated in social dance programs in senior education institutions senior class, senior college, senior shool, Senior welfare center, social welfare center, university, school of lifelong education, religion community) in Seoul. After a survey was conducted, the answer sheets from 428 respondents were analyzed except some incomplete ones. As for data handling, a SPSS Windows Ver. 15.0 program was employed, and a frequency analysis, exploratory factor analysis, reliability analysis, pearson chi-square, independent-samples t-test, one-way ANOVA and binary-logistic regression were utilized. The findings of the study were as follows: First, self-perceived age by social population characteristics shows significant difference in all lower factors of self-perceived age(Look age, Feel age, Interest age, Do age) as chronological age, education level. Also, the marriage status shows significant difference only in interest age and feel age, the economic level shows only in look age, interest age and feel age. Second, the social dance instructor preference by social population characteristics shows significant difference in the all lower facts of social dance coaches preference(gender, age, education level, instructor career) up to educational level. Also, chronological age without the instructor career, economic level without instructor gender show the significant difference in the lower facts of all social dance instructor preference. Also, marriage status shows the significant difference in the educational level of the instructor. Third, the analysis of the influence of self-perceived age on the instructor preference shows all gender(B=.458), age(B=.483) and educational lever(B=.76) without career were influenced in significant (+) way.

        세그먼트화 폴리우레탄을 이용한 고분자 마이크로 액츄에이터의 제작 및 고분자 전극의 상태에 따른 구동성능

        정영대(Young Dae Jung),박한수(Han Soo Park),조남주(Nam Ju Jo),정해도(Hae Do Jeong) Korean Society for Precision Engineering 2005 한국정밀공학회지 Vol.22 No.2

        This paper is focused on the development of the flexible electrode for disc-type polymer actuators using Segmented Polyurethane(SPU). This paper consists of two parts. The one is about the mechanical property such as elastic modulus. these parameters mainly affect behaviors of polymer actuators and the other is about the electro-chemical property such as the surface resistance of the composite electrode affects the strength of electrostatic force, results in the deformation of polymer actuators. The Young's modulus was measured by UTM. As result, by increasing the modulus of a body of polymer actuators, the maximum displacement of polymer actuators are decreased. The surface resistance of the electrode was measured by 4 point probe system. Compared with the conductive silver grease, the displacement of polymer actuators using carbon black(CB) composite electrodes is comparably small but CB composite electrode should be the practical approach for the improvement of the performance of all-solid actuators, compared with another types of electrode materials.

        정서영(Jung Seo-Young),이대균(Lee Dae-Kyun) 한국어린이미디어학회 2010 어린이미디어연구 Vol.9 No.1

        본 연구는 사립유치원 원감들이 유치원에서 중간자적 위치의 삶을 살아가면서, 아픔으로 느끼는 다양한 애환과 다시 힘을 내게 하는 보람된 요소들, 그리고 미래에 대한 희망 등을 질적 연구방법을 통해 밝히고자 하였다. 2009년 9월부터 11월까지 총 11주 동안, 11명의 사립유치원 원감들을 연구 참여자로 하여 심층면담과 관련문서, 연구자의 반성적 저널쓰기를 통해 자료를 수집하였다. 수집한 자료를 분석한 결과 사립유치원 원감들은 애환의 요소로 원장과 교사와의 사이에서 매개체 역할, 모든 오류와 민원의 해결사 역할, 유아의 안전 문제로 인한 학부형 관계, 원감 자격 연수 과정 없이 업무를 시작함과 과도한 원아 모집 경쟁, 그리고 육아를 겸하는 데서 오는 어려움을 호소하였으며 보람의 요소로는 원장으로부터 인정 받음과 학부모의 격려 및 업무 수행에서 오는 성취감, 그리고 교사의 성장과 유치원의 발전을 보며 보람된 마음을 가질 수 있다고 하였다. 또한 앞으로 원장 연수를 받고 본인의 원을 경영하면서 자신의 교육철학이 반영된 좋은 프로그램을 마음껏 실천해 보기를 희망하고 있었다. The purpose of this research is to understand the position and life of the vice-principals who carry out their duties as a mediator and to clarify the meaning of it. The eleven participants for this research are selected out of the vice-principals serving in Gyung-gi and Cheon-an, Dae-jeon province considering various careers and characteristics. The duration of the research lasted for eleven weeks. To collect the data we used in-depth interview, phone interview, and e-mail interview with each participant and wrote a journal to record the flow and characteristics of the research. First of all, the private kindergarten vice-principals had so much difficulties in carrying out their duties. The first element can be the difficulties in playing a role as a mediator between the president who substantially runs the kindergarten and the teachers who educate the children near by. The second element of difficulties is the confusion caused by dealing with all the errors and public grievance whether anytime or anywhere. The third element is the safety issue of the children that can takes place any time and dealing with the parents with that issue. The forth element is to choose the vice-principals out of the president's authority unlike the public kindergartens that hire through systematical steps to be a vice-principals. The fifth element is the excessive competition in recruiting new students leads to overaction that ruins the principle and fundamental rule. The last element is the difficulty of maintaining both teaching and raising their own kids at the same time. Secondly, they felt worthwhile, having the motive power that enables the vice-principals's to move forward when they get the recognition from the president, which turned out as the best factor. Other factors also can be an encouragement from parents, a feeling of the satisfaction and achievement after an event. Besides, when the teachers are cooperative and new students keep signing up they find it worthwhile. Thirdly, the participants found the biggest hope in the systematically legitimate way of children educator that became most considerable meaning and they could get the feeling of the pride. After that, they talked about getting a training to be a president that can be the next goal for them to run their own kindergarten adapting good philosophy and programs.

      • 한국인에서 혈소판 당단백 Ⅱb/Ⅲa 유전자 다형성과 관동맥 성형술 후 재 협착과의 관계

        이민수,이정우,김보영,임대승,강정아,김정희,김윤철,성보영,최성준,성인환,전은석 충남대학교 의과대학 지역사회의학연구소 2000 충남의대잡지 Vol.27 No.2

        Platelet aggregation is the final pathway of acute coronary syndrome such as acute myocardial infarction and unstable angina. Platelet glycoprotein IIb/IIIa is a membrane receptor for fibrinogen and yon Willebrand factor and it plays an important role in platelet aggregation and in the pathogenesis of acute coronary syndrome. It is known that polymorphism of the gene that encoding platelet glycoprotein IIb/IIIa(PI^A1/A2) is strongly related to acute coronary syndrome in Caucasian, but not in Koreans. We investigated relationship between platelet glycoprotein llb/Illa gene polymorphism and restenosis of coronary artery after angioplasty in Koreans. Total 371 patients(M=251. F=120) were enrolled. Angioplasty group comprised 143 patients who underwent coronary angioplasty, and in the angioplasty group, restenosis group comprised with the 65 patients who had restenotic lesion over 50% of luminal diameter in follow-up coronary angiography. Normal group comprised 153 patients who had no significant angiographic lesion and variant angina group comprised 75 patients who were positive in ergonovine test. Genomic DNA was extracted from peripheral arterial blood. To determine the frequency of P1^A1/A2 genotype, polymerase chain reaction(PCR) was done and the product was restricted with Mspl. 3%. agarrose gel electrophoresis showed restriction fragment length polymorphism. Clinical profile and risk factor were also reviewed. Among all 371 patients of study group, genotype of only one patients in restenosis group if is proven to be PI^A1/A2 heterozygote. All patients of normal study group, no restenosis group, and the other patients in restenosis group have an PI^A1 homozygote genotype. In our study, platelet glycoprotein IIb/Illa polymorphism has no relationship with restenosis of the coronary artery after angioplasty in Koreans. But the genotypic frequency of platelet glycoprotein IIb/IIIa gene polymorphism in Koreans is concordant with that of previous studies.

        Seung-Joon Oh, In-Kyung Jeong, Young-Seol Kim, Young-Kil Choi, Jeong-Ryung Paeng¹, Jung-Hwan Bae and Hyun-Dae Shin²Department of internal Medicine, College Medicine, Endocrine Research Institute¹. Department of Rehabilitation, College of Oriental Medicine², Seoul, korea. Bady Fat Reduction Effects of Red Ginseng Compound Preparation on the Patients with Obesity. Proceedings of International Symposium on East-West Medicine, Seoul. 244-254, 1999.-Obesity can be defined as a metabolic disease due to an increased state of fat tissues caused by an imbalance of calorie intake and use. Recently, in Korea by improvement and westernization of food intake, along with decrease in exercise activities, the prevalence of obesity has increased greatly. Our objectives were to study stability and effects of decrease in body fat by administering red ginseng compound preparation (known to have body fat decreasing effects in laboratory animals) to obesity patients on low calorie diets. Changes in weight and body fat were measured while carrying out calorie-restricted diets on patients for 4 weeks, then administering red ginseng compound preparation for another 4 weeks. The patients were 20 people whose BMI were 25kg/㎡ or over and whose percent body fat was also 30% or over when tested by bioelectrical conductivity. 1. Changes in weight were from 70.04kg(base line) to 67.43kg(after taking red ginseng compound preparation). 2. In similar sense, BMI decreased from 27.12kg/㎡(base line) to 26.56kg/㎡(after dieting), and further to 26.01kg/㎡ (after taking red ginseng compound preparation). The BMI seemed to decrease significantly compared to the baseline after the use of red ginseng compound. 3. Waist hip ratio was changed from 0.8858(base line) to 0.8728, but it was statistically insignificant. 4. The percent body fat was 35,16%(base line), 33.87%(after dieting), and 31.68%(after taking red ginseng compound preparation). 5. Complete blood cell count and blood chemisrty remained unaffected by the administration. 6. In concern to endocrinologic studies, T3 decreased from 118.7 to 98.2ng/dL, and T4 increased from 8.8 to 9.2㎕/ dL. Epinephrine showed a tendency to decreased from 0.27 to 0.25 ng/mL, and norepinephrine increased from 0.39 to 0.44ng/mL. 7. Leptin was not changed. 8. Some patients complained adverse effects; constipation(5 patients, may be due to diet therapy), fatigue (2 patients), pruritus(2 patients), flushing(s patients), dizziness(3 patients) and epigastric discomfort(2 patients). However their symptoms were mild, so medication did not stopped. In conclusion, loss of weight without significant side effects was observed during low calorie diet and red ginseng compound preparation administration. This is thought to be in relation to sympathetic nerve system rather than adrenal gland. Also, further long0term studies should be required, since the observed results were based on short-term changes in weight.

      • 위암 환자의 복강내 투여를 위한 Activated Charcoal-Alginate Bead 제형으로부터 Mitomycin C의 용출 거동

        Locoregional recurrence is the most common type of recurrence in surgical operation of gastric adenocarcinoma, and peritoneal dissemination is one of the most difficult problems in advanced gastric adenocarcinoma treatment. Because the peritoneal cavity is the most common site of the first recurrence after gastric cancer resection, intraperitoneal chemotherapy seems a logical choice for cancer chemotherapy. In this study, Mitomycin C (MMC)-activated charcoal (CH)-alginate (ALG) beads were prepared by the mixtures of CH particles adsorbed with MMC as an anti-cancer drug and aqueous alginate solution. The alginate is recognized as biodegradable, nontoxic, and biocompatible. The release of MMC from the beads in 0.1 M Tris buffer was stable and continuous until about 1 week. The MMC-CH-ALG beads can be applied in the peritoneal cavity for intraperitoneal chemotherapy since they provide a good adhesiveness on the tissue and controlled release pattern of the drugs.

In this scheme, Less complex regions are segmented into variable sized blocks(4×4, 8×8) and high-detail regions are segmented into 4×4 blocks of various edge classes. And Quad-Tree(QT) method is used for block data transmition.

      • 단체수요를 고려한 서비스산업의 수익관리 최적화 모형에 관한 연구 : 항공사 수익관리 모형을 중심으로 An Application Airline Industries

        정대영,윤문길 한국항공대학교 경영연구소 2000 경영연구 Vol.7 No.2

        수익관리(Revenue Management)는 공급과 수요관리의 문제점을 해결하기 위한 새로운 접근방법으로서 시장에서의 수요와 공급을 적절히 조절함으로써 수익을 최대한 시키는 경영기법이며, 경영과학분야와 실무적으로는 항공사 및 기타 소멸성 자산(Perishable-Asset)을 운용하는 서비스 기업에 빠르게 확산되고 있는 분야중의 하나이다. 본 연구에서는 할인요금에 대한 좌석할당에 있어서 미래에 발생할 수 있는 정상요금 예약의 기대수익보다 현재 요구된 할인요금의 수익가치가 더 크다면 할인요금 예약은 수용되어야 한다고 Littlewood[42]가 제안한 복수요금형태에 기반을 둔 좌석재고 통제규칙을 기초로 동적 계획법(DP: Dynamic Programming)의 특성을 고려하여 재고통제를 위한 수익관리기법에 관한 연구를 수행하였다. 모의실험은 제시된 최적화 모형과 판매허용용량을 정하여 허용가능 용량내에서 판매가능 여부를 결정하는 표준형 네스팅 방식을 통한 매출액의 비교를 실시하였다. Revenue management is a method that can help a firm sell the right inventory unit to the right customer at the right time and for the right price. It guides the decision of how to allocate undifferentiated units of limited capacity to available demand in a way that maximizes profit or revenue. This paper examines the problem of proper(optimal) control over the seat allocation on flight. We formulate and analyze a Markov Sequential Decision Model for airline revenue management on multiple-price by considering a simple form of airline group demand. Our model allows cancellation, no-show and overbooking. In this paper, we make assumptions on a single-leg flight but not on the arrival patterns for the various fare classes. As a result of Simulation, our numerical examples show that revenue gains of up to 9% are possible with our model, compared with an standard nesting method. It is demonstrated that our model is valid and possible application to airline industry and applicable to other problem of revenue management with perishable service or product such as ISP, Cruise, hotel, Mobile terminal with very short Product life cycle. The purpose of this paper has been not so much to provide a model for a specific airline industry, as to indicate the nature and significance of the general service industry problem and to demonstrate one approach, and its shortcomings, for resolving it. It is hoped that the presentation of these results will stimulate additional research, either along the lines suggested or in new directions, for what appears to be an important and pressing decision problem.
