        金成洙,河璡桓,姜永周,金洙賢,金永東,宋大鎭 제주대학교 1990 논문집 Vol.30 No.-

        To evaluate the composition of Gae-Woo Jeot which is one of important traditional salted and fermented sea foods in Cheju Do, changes of nucleotides and their related compounds, free amino acids, TMAO(trimethylamine oxide), TMA(trimethylamine) contents and histological properties during fermentation was examined. AMP was as high as 3.6?mole/?? in raw small abalone but IMP content was only trace while hypoxanthine and IMP was dominant in raw topshell-4.5 mole/?? and 4.3??mole/?? respectively. Hypoxanthine was predominant in 65 days fermented Gae-Woo Jeot. Main amino acid in Gae-Woo Jeot were glycine, arginine, glutamic acid, alanine, valine and histidine in order. These were consisted 50~60% of the total free amino acid while phenylalanine, tyrosine, methionine and isoleucine were poor in content. During fermentation TMAO decreased slowly and eventually disappeard within 85 days while TMA was increased until 65 days and started to decrease down to 6~9mg%. Muscle texture showed the disappearance of elasticity soon after the adding of 10% salt while no change of texture was oberved until 50 days of fermentation in 20% salt group.

      • 인버터 구동용 유도전동기 고정자 권선의 절연특성 연구

        황돈하,김동희,이광식,정원영,김영훈,오승훈 영남대학교 공업기술연구소 1999 工業技術硏究所論文集 Vol.27 No.2

        Inverters with high speed switching and advanced PWM techniques are widely used for variable speed applications. But some adverse effects on the stator winding insulation are reported due to excessive voltage stress, which results in the premature insulation breakdown. This is aggravated by the high switching speed of modem switching devices such as IGBT (Insulated Gate Bi-polar Transistor) with which the rate of rise in voltage (dv/dt) increases considerably. In this paper, the test results for evaluation on the stator winding insulation of 310V induction motors are presented. Also, the insulation characteristics are presented in order to analyze the insulation strength under high voltage due to high switching speed of IGBT PWM inverter. 26 induction motors of 6 types with different wires and insulation techniques are built and thoroughly tested. The maximum partial discharge (PD) magnitude (Qm) and the discharge inception voltage (DIV) are obtained by PD test. Under AC current test, the rate of change in AC current (ΔI) and the change in dissipation factor (Δtanδ) are measured. From the above test data, the effects due to different wires and insulation techniques on the insulation characteristics of low-voltage induction motors are compared and analyzed. The insulation technique to enhance the insulation strength is suggested from the test results.

        박경숙,김계옥,송영준,정동영,정인숙 국립특수교육원 2004 연구보고서 Vol.- No.12

        본 연구는 학교 학습 특히. 국어와 수학에서 부진을 나타내는 아동을 선별 또는 진단하고, 이들이 부진을 나타내는 영역과 수준을 파악하여 이들의 교육계획 수립과 적용에 필요한 정보를 제공할 수 있는 개인용 기초학력 검사(Korea Institute for Special Education-Basic Academic Achievement Tests KISE-BAAT)의 개발을 위해 기초학력의 개념과 기초학력의 구성요인 등을 탐색하여 KISE-BAAT의 구성모형을 개발한 다음, 그 모형을 토대로 검사문항의 성취기준을 설정하고, 그에 따라 제7차 교육과정의 내용을 토대로 범교과적으로 통용할 수 있는 KISE-BAAT의 검사문항을 개발하였다. 본 연구는 유ㆍ초ㆍ중ㆍ고등학교 및 대학교의 학생 1,499명을 대상으로 KISE-BAAT의 예비검사를 실시하고, 그 결과를 토대로 검사문항의 변별도와 양호도 등을 분석하여 최종 검사문항을 선정하였다. 그리고 본 연구는 KISE-BAAT의 표준화를 위해 전국의 유치원, 초등학교와 중학교에 재학중인 5~l4세의 아동 5,977명을 대상으로 검사를 실시하여 규준의 작성 및 해석에 필요한 기초 통계를 산출하였으며, 신뢰도와 타당도를 검증하였다. 본 연구의 결과를 요약하면 다음과 같다. 첫째, 본 연구는 학력을 기초학력 과 심화학력으로 구성 된다고 가정 하여 심화학력에 의 한 학업성취를 제외한 학업성취를 기초학력으로 규정하고, 만 5세부터 14세까지 아동의 기초학력을 측정하는 개인용 기초학력검사인 KISE-BAAT를 개발하였다. KISE-BAAT는 KISE-BAAT(읽기), KISE-BAAT(쓰기), KISE-BAAT(수학)의 3개 검사로 구성되는 복합심리검사(battery)로서 각각의 소검사는 가형과 나형 2종의 동형검사로 구성되어 교육 프로그램의 사전ㆍ사후효과, 일반화 및 전이효과 측정을 용이하게 하며, 백분위수ㆍ환산점수ㆍ학력지수 학년규준의 제시로 아동의 기초학력의 지체 여부와 정도에 대한 진단과 더불어 교육계획의 수립ㆍ시행 및 평가에 활용할 수 있도록 하였다. 따라서 KISE-BAAT는 학교학습의 도구가 되는 읽기ㆍ쓰기ㆍ수학의 기초학력을 종합적으로 측정할 수 있으며, 결과를 다양하게 분석할 수 있는 개인용 기초학력검사라 할 수 있다. 둘째, KISE-BAAT의 신뢰도를 검증한 결과, 동형검사 신뢰도계수는 KISE-BAAT(읽기) 가형과 나형 .82, KISE-BAAT(쓰기) 가형과 나형 .69, KISE-BAAT(수학) 가형과 나형 .89로 나타났고, 반분신뢰도 계수는 KISE-BAAT(읽기) 가형 .93, 나형 .92, KISE-BAAT(쓰기) 가형 .91, 나형 .94, KISE-BAAT(수학) 가형과 나형 모두 .98로 나타났으며, 문항반응이론 신뢰도 계수는 KISE-BAAT(읽기) 가형과 나형 모두 .90, KISE-BAAT(쓰기) 가형 .99, 나형 .96, KISE-BAAT(수학) 가형 .97,나형 .99로 나타났다. 그리고 측정의 표준오차는 KISE-BAAT(읽기) 가형 .76, 나형 .85, KISE-BAAT(쓰기) 가형 .90, 나형 .92, KISE-BAAT(수학) 가형 2.11, 나형 2.32로 나타났으며, 재검사 신뢰도 계수는 KISE-BAAT(읽기) 가형 과 나형 모두 .96, KISE-BAAT(쓰기) 가형 .95, 나형 .96, KISE-BAAT(수학) 가형과 나형 모두 .98로 나타났으며, 문항의 내적 일치도 계수도 KISE-BAAT(읽기) 가형과 나형 모두 .98, KISE-BAAT(쓰기) 가형과 나형도 모두 .98, KISE-BAAT(수학) 가형과 나형 모두 .99로 나타났다. 따라서 KISE-BAAT의 KISE-BAAT(읽기), KISE-BAAT(쓰기), KISE-BAAT(수학) 가형과 나형은 모두 측정학적으로 아동의 기초학력을 측정하는데 있어 일관된 수치와 정보를 제공해 주는 도구라 할 수 있다. 셋째, KISE-BAAT의 타당도를 검증한 결과, KISE-BAAT(읽기) 가형ㆍ나형과 KEDI-기초학습기능점사 읽기Ⅱ의 상관계수는 각각 .50, .56, KISE-BAAT(쓰기) 가형ㆍ나형과 KEDI-기초학습기능검사 읽기Ⅰ의 상관계수는 각각 .68, .67, KEDI -기초학습기능검사 쓰기와 상관계수는 각각 .51, .68, KISE-BAAT(수학) 가형ㆍ나형과 KEDI-기초학습기능검사 셈하기의 상관계수는 각각 .70, .75로 나타났다. KISE-BAAT와 KEDI-기초학습기능검사는 매우 다른 영역과 내용으로 구성되어 있고, 서로 다른 개념을 기초로 제작된 것이나 두 검사간의 상관계수는 비교적 양호한 상태라 할 수 있다. 그리고 구인 타당도의 한 측면을 나타내는 KISE-BAAT 검사영역 상호간 상관계수는 전체적으로 KISE-BAAT(읽기) 가형이 .23에서 .93을, 나형이 .19에서 .91을 범위로 하고 있으며, KISE-BAAT(쓰기) 가형이 .70에서 .95를, 나형이 .73에서 .95을 범위로 하고 있고, KISE-BAAT(수학) 가형이 .81에서 .94를, 나형이 .83에서 .94를 범위로 하고 있다. 따라서 KISE-BAAT는 개발의 과정에서부터 이루어진 내용 타당도의 확보를 위한 노력 등으로 기초학력을 측정하는데 타당한 도구라 할 수 있다. 따라서 본 연구에서 개발한 KISE-BAAT는 아동들의 읽기ㆍ쓰기ㆍ수학 기초학력을 측정하는 신뢰롭고 타당한 개인용 기초학력검사라 할 수 있다. 그러나 KISE-BAAT는 연구 수행상의 제한점과 함께 앞으로 활용의 과정에서 나타나는 문제점을 계속 수정 보완해야 한다. 뿐만 아니라 KISE-BAAT는 문항 편파성 분석 (item bias analysis)과 일반화 가능도 분석에 대한 연구와 더 폭넓은 타당도 분석을 위해 사고력 검사나 다른 학력검사와 공인타당도 분석 등을 연구해야 한다. 그래야만 KISE-BAAT는 아동의 기초학력을 진단 평가하는데 더욱 유용하고 정교한 검사로 발전해 갈 수 있을 것이다. The purpose of this study is to develop a basic academic achievement test battery, KISE-BAAT(Korea Institute for Special Education-Basic Academic Achievement Tests) which provides information about a student's achievement and performance in reading, writing and math. In order to develop the test battery the concept and construct of basic academic achievement were investigated. Subsequently the framework of the test battery was developed, the achievement standards of test items were established and test items were developed based on the current seventh national curriculum. The item tryout of KISE-BAAT was administered to 1,499 students in grades K, 2, 5, 8, 12 and in college. Item difficulty and discrimination data were obtained. Items were selected by reviewing all data available. The national standardization was administered to 5,977 students in grades K through 9. Data obtained from the standardization test used to develop national norms for the test and reliability and validity of the test. The results of the study is as follows. First, KISE-BAAT, a test battery for an individual, consists of three tests of reading, writing and math. Each test has Form A and Form B. KISE-BAAT is used to assess the achievement of an individual student of age 5 through 14. The data can be used for general instruction, remedial instruction and evaluation of an educational program. Second, Several methods were used to estimate the reliability of KISE-BAAT. Alternate-form reliability coefficient of KISE-BAAT(Reading) is .82, KISE-BAAT(writing) .69, KISE-BAAT(Math) .89. As for Split-half Reliability coefficient of each alternate form of KISE-BAAT(Reading) shows .93 and .92. In KISE-BAAT(writing) .91 and .94 are presented. In KISE-BAAT(Math) .98 in common. Item response theory reliability coefficient of each alternate form of KISE-BAAT(Reading) are .98 in common. In KISE-BAAT(writing) .90 and .92 are presented. In KISE-BAAT(Math) .97 and .99 are presented. The standard error of measurement of each alternate form of KISE-BAAT(Reading) is .76 and .85, for KISE-BAAT(writing) .90 and .92 and for KISE-BAAT(Math) 2.11 and 2.32. Test-retest reliability coefficient of each alternate form of KISE-BAAT(Reading) are .96 in common. In KISE-BAAT(writing) .95 and .96 are presented. In KISE-BAAT(Math) .98 is presented in common. Third, the criterion-related validity of KISE-BAAT in terms of the relationship with KEDI-Basic Academic Ability Test was examined. The validity coefficient of each alternate form of KISE-BAAT(Reading) and Reading II of KEDI-Basic Academic Ability Test showed .50 and .56 repectively. The validity coefficient of each alternate form of KISE-BAAT(Writing) and Reading I of KEDI-Basic Academic Ability Test showed .68 and .67 respectively. Reading I of KEDI-Basic Academic Ability Test was matched to KISE-BAAT(Writing) since it has features of writing ability. The validity coefficient of each alternate form of KISE-BAAT(Reading) and Writing of KEDI-Basic Academic Ability Test showed .51 and .68. The validity coefficient of each alternate form of KISE-BAAT(Math) and Computing of KEDI-Basic Academic Ability Test showed .70 and .75. As for intercorrelation coefficents between subtests KISE-BAAT(Reading) range form .23 to .93. In KISE-BAAT(Writing) from .70 to .96 and in KISE-BAAT(Math) from .81 to .94. Based on all the data mentioned above KISE-BAAT can be said a reliable and valid test battery which assess students' ability in reading, writing and math. However, KISE-BAAT should be modified and complemented in order to compensate its own limitations. Future research on item bias analysis and generalizability needs to be done. Criterion-related validity to examine the relationship with other psychological tests or achievement tests also should be done to validate KISE-BAAT further. Case studies and suggestions from test users will also contribute to improve KISE-BAAT.

      • 고속전철 추진 시스템의 미끄럼 방지 제어기법에 관한 연구

        황돈하,김동희,노채균,심광열,조규판,정원영 영남대학교 공업기술연구소 1999 工業技術硏究所論文集 Vol.27 No.2

        Induction motor drive with PWM inverter control has been developed for Korean High Speed Railways. To improve traction performance, the anti-slip control(ASC) to recover adhesion must be considered. This paper describes a novel hybrid anti-slip control method for the induction motor drive. By introducing the vector control for drive system, quick response of the motor torque can be achieved when wheels are going to slip. A hybrid control scheme by mixing two conventional control methods (slip velocity feedback control and slip detection pattern control) for wheel slip and re-adhesion is proposed. This control method is simulated by motor drive, train load, and friction-creep models. The train running simulation results based on induction motor vector control with PWM inverter show that good re-adhesion characteristics are obtained.

        ( Yeung Keun Choi ),( Fakhar Ud Din ),( Dong Wuk Kim ),( Yong Ll Kim ),( Jong Oh Kim ),( Sae Kwang Ku ),( Jeong Chan Ra ),( Jae Wook Huh ),( Jangik L Lee ),( Dong Hwan Sohn ),( Chul Soon Yong ),( Han 영남대학교 약품개발연구소 2014 영남대학교 약품개발연구소 연구업적집 Vol.24 No.0

        The conservative single-layered wound dressing system is decomposed when mixed in polyvinyl alcohol (PVA) solution, which means it cannot be used with a temperature-sensitive drug. The goal of this investigation was to make an amniotic membrane extract (AME)-loaded double-layered wound dressing with an improved healing result compared to the conservative single-layered wound dressing systems. The double-layered wound dressing was developed with PVA/sodium alginate using a freeze-melting technique; one layer was PVA layer and the other was the drug-loaded sodium alginate layer. Its gel properties were assessed compared to single-layered wound dressings. Moreover, in vivo wound-healing effects and histopathology were calculated compared to commercial products. The double-layered wound dressing gave a similar gel fraction and Young`s module as single-layered wound bandages developed with only PVA, and a similar inflammation ability and WVTR as single-layered wound dressings developed with PVA and sodium alginate. Our data indicate that these double-layered wound bandages were just as swellable, but more elastic and stronger than single-layered wound dressings comprised of the same polymers and quantities, possibly giving an acceptable level of moisture and accumulation of exudates in the wound zone. Compared to the commercial product, the double-layered wound dressing comprising 6.7% PVA, 0.5% sodium alginate and 0.01% AME significantly enhanced the wound-healing effect in the wound-healing test. Histological investigations showed that superior full-thickness wound-healing effects compared to the commercial product. Therefore, the double-layered wound dressing would be an outstanding wound-dressing system with improved wound healing and good gel property.

        Dept. of Oriental Rehabilitation Medicine, College of Oriental Medicine, Dong Guk University, Dept. of Oriental Rehabilitation Medicine, College of Oriental Medicine, Kyunghee University* Backgrounds and Purpose : Pyrite is one of the important prescription that has been used in oriental medicine for healing of fracture. The purpose of this study is to know the effect of Pyrite on the healing of tibia fracture. Materials and Methods : We used 42 male Sprague-Dawley rats of 8-12 weeks aged. They were divided two groups, control and experimental. All rats of each group was fractured by instrument designed by Bonnarens & Einhorn. Pyrite was orally administered to the experimental group. At post-fracture 2 days, 4 days, 1 week, 2 weeks, 3 weeks, 4 weeks and 5 weeks, three rats was sacrificed in each group. From them we gained bony-segments of healing process of fractured tibias. Also at each time we sampled rats, venous blood and checked Ca, P and Alcaline phosphatase in the serum. We stained the specimens with Goldner, s modified Masson,s Trichrome. And then we measured Bone histomorphometry using Bioquant computer program of image-analysis system. The measurements included static parameter and dynamic parameter. We measured the thickness of osteoid and callus as static parameter, and mineral apposition rate as dynamic parameter. We observed specimens, histomorphologic change of unioned callus of each group under the microscope of 100 magnifications. Results and Conclusions : 1. In the change of Ca, P there was no significant change between experimental and control group. But from 3 weeks of fracture ALP in experimental group was increased compared with control group. Expecially after 4 and 5 weeks of fracture ALP in experimental group was significantly increased compared with control group. 2. The Osteoid Thickness was increased in experimental group compared with control group at 1, 3, 4 and 5 weeks of fracture. Expecially at 1 and 5 weeks Osteoid Thickness in experimental group significantly increased compared with control group. 3. The Callus Thickness was not significantly changed in experimental and control group from 1 to 5 weeks of fracture. 4. The MAR in experimental group was significantly increased compared with control group after 4 weeks of fracture. 5. In histomorphology from 4 days to 3 weeks of fracture, callus formation, osteoid formation and maturity in experimental group was rapidly stimulated compared with control group. From above result, we expect development of a new stimulator healing fracture by using pyrite.
