This study was conducted to evaluated musculoskeletal subjective symptoms and the degree of stress of industrial workers to present fundamental materials of preventive oriental medicine for improving their health and quality of life. During the medical examination with oriental medicine method, presence of subjective symptoms of musculoskeletal pain, Psychosocial Well-being Index(PWI) and life style were checked by using questionnaire method in 474 industrial workers. The collected data were analyzed with crosstabs, ANOVA and T-test. The results were as follows; 1. In general differences according to musculoskeletal subjective symptoms, education level of high school graduation had significantly higher distribution than that of below middle school or above university graduation in the pain present group. 2. In the musculoskeletal subjective symptoms and the degree of stress, all of Factor1, Factor2. Factor3, Factor4. and PWI had higher score in pain present group than in pain free group and the difference was statistically significant. 3. According to degree of stress and general character of subjects, single and education level of high school graduation had high score in Factor2, Factor3 and PWI. Factor1 and Factor3 was high in income group of low 1.49 million won. Factor2, Factor4, and PWI was high significantly in income group of 1.50 - 2.99 million won. In job type, manufacturing worker group had significantly high score in Factor3. 4. In degree of stress and life style difference, there was significant difference in PWI score in the field of alcohol chinking, smoking, exercise, obesity except sleeping hours. In the present study. as a result, it is found out that musculoskeletal subjective symptoms present group had higher score in psychosocial stress across the fields than symptom-free group and it is recommended that continuous studies on the relationship of job-related musculoskeletal disorders and psychosocial stress should be performed for improvement and prevention of mental and physical health of industrial worke

김기철,김지민,김대진,Kim Ki-Chul,Kim Ji-Min,Kim Dae-Jin 한국생명과학회 2005 생명과학회지 Vol.15 No.1
십전대보탕에 들어가는 한약재 10종을(국산 7종, 중국산 10종)을 수집하여 일반성분과 중성세제섬유소(neutral detergent fiber, NDF), 식이섬유(total dietary fiber, TDF; insoluble dietary fiber, IDF; soluble dietary fiber, SDF)를 분석하였다. 십전대보탕 재료 중 국내산 7종, 중국산 10종에 있어서 일반성분과 식이섬유는 국내산과 중국산간의 차이가 크지 않았다. 그러나 중성세제섬유의 경우 건조물 기준으로 국내산 $35.24\%$, 중국산 $58.64\%$로 차이가 크게 나타났다 국내산 7종의 총탄수화물(CHO)과 NDF 간에는 Y=0.32X+60.96, r=0.61(p<0.01), 총탄수화물(CHO)과 NFE간에는 Y=0.65X+32.88, r=0.76(p<0.001)로서 유의한 회귀식과 상관이 도출되었다. 그러나 총탄수화물(CHO)과 NFC간에는 Y=-0.07X+80.93, r=0.10로서 회귀식이 도출되었으나 유의성은 없었다. 중국산 10종의 총탄수화물(CHO)과 NDF간에는 Y=0.53X+49.64, r=0.69(p<0.001), 총탄수화물(CHO)과 NFE간에는 Y=0.50X+46.42, r=0.71 (p<0.01)로서 유의한 회귀식과 상관이 도출되었다. 그러나 총탄수화물(CHO)과 NFC간에는 Y=0.10X+78.21, r=0.10로서 회귀식이 도출되었으나 유의성은 없었다. 국내산 7종의 TDF와 IDF간에는 Y=0.96X+4.08, r=0.99(p<0.01), TDF와 SDF간에는 Y=-6.87X+62.97, r=0.51(p<0.01)로서 유의한 회귀식과 상관이 도출되었다. 중국산 10종의 TDF와 IDF간에는 Y=0.96X+3.14, r=0.99(p<0.01), TDF와 SDF간에 Y=-8.71X+58.96, r=0.50(p<0.01)로서 유의한 회귀식과 상관이 도출되었다. 국내산과 중국산 7종 식이섬유의 t-test 결과 TDF와 IDF는 평균이 양측검정결과 유의하게 다르지 않았으나 SDF는 평균이 유의하게 달랐지만 단측검정 결과 유의하지 않았다. This study was conducted to determine the total carbohydrate (CHO), nitrogen free extract (NFE), non fiberous carbohydrate (NFC) and ditery fiber (NDF, neutral detergent fiber; TDF, total dietary fiber; IDF, insoluble dietary fiber; SDF, soluble dietary fiber) of 17 kinds of domestic and Chinese herbs. The samples were dried at 60t for 24 hrs and ground to pass a 0.5mm screen. The contents of NFE was ranged from $85.73\%\;to\;57.57\%$, NDF was ranged from $85.72\%\;to\; 29.74\%$, CHO was ranged from $92.68\%\;to\;63.01\%$, TDF was ranged from $87.33\%$to 17.21, IDF was ranged from $86.37\%\;to\;14.56\%$, SDF was ranged from $6.06\%\;to\;0.97\%$ on domestic herbs in dry matter basis. NFE was ranged from $95.33\%\;to\;35.24\%$, NDF was ranged from $71.48\%\;to\;29.74\%$, CHO was ranged from $78.77\%\;to\; 35.24\%$, TDF was ranged from $86.43\%\;to\;16.22\%$, IDF was ranged from $85.98\%\;to\;13.04\%$, SDF was ranged from $4.13\%\;to\;0.45\%$ on Chinese herbs in dry matter. The several components of domestic and Chinese herbs were not significantly of TDF and IDF, but SDF was significantly by tow-tailed test. The correlationship of several herbs were r=0.99 between TDF and IDF (p<0.01), r=0.51 between TDF and SDF (p<0.01)on domestic herbs. The correlationship of 10 kinds herbs r=0.99 between TDF and IDF (p<0.01), r=0.50 between TDF and SDF (p<0.01) on Chinese herbs, respectively.

This paper shows an implementation of video codec (coder/decoder) on an embedded system. The video codec supports both H.261 and H.263 standards. For efficient real-time processing, the video codec is partitioned into a software module and a hardware module. Both modules are codesigned on an embedded system. The software module is processed on a real-time operating system and a RISC processor. It cooperates with the hardware module to compress and decompress images in real time. AMBA (Advanced Microcontroller Bus Architecture) AHB (Advanced High-performance Bus) is used as the system bus. The hardware module works both as AHB masters and as AHB slaves. The encoder part of the hardware module operates in a pipelines mode to compress images in real time. The video codec compresses 15 CIF frames and simultaneously decompresses 15 CIF frames in a second according to H.261 or H.263 standard at 33 MHz frequency. 본 논문에서는 H.261과 H.263 표준을 모두 만족하는 영상 코텍을 임베디드 시스템에서 구현한다. 효율적인 실시간 처리를 위하여, 영상 코덱은 하드웨어 모듈과 소프트웨어 모듈로 구분되어 임베디드 시스템에서 통합 설계된다. 소프트웨어 모듈은 실시간 운영체제와 RISC 프로세서를 이용하여 수행되며, 하드웨어 모듈과 연동하여 실시간으로 영상을 압축하고 복원한다. 시스템 버스로는 AMBA AHB가 사용되며 하드웨어 모듈은 AMBA AHB의 마스터(master)와 슬레이브(slave)의 역할을 모두 수행한다. 영상 압축과정을 실시간으로 처리하기 위하여 인코더의 하드웨어 모듈은 파이프라인으로 설계된다. 구현된 영상 코덱은 H.261과 H.263 표준에 준하여 33㎒의 동작 주파수에서 1초 동안에 CIF 화면 15장을 동시에 압축하고 복원한다.

체육과 교육과정의 개발과 적용과정의 간극 요인 및 대응방안 탐색
김기철(Kim, ki-chul) 성신여자대학교 교육문제연구소 2012 교육연구 Vol.55 No.-
이 연구의 목적은 국가수준 체육과 교육과정의 개발과 적용과정에서 발생하는 ‘간극’의 실체를 파악함은 물론, 이를 극복할 수 있는 구체적 대안마련의 여건을 조성하기 위함이다. 이러한 연구목적을 달성하기 위해 이 연구는 제 7차와 2007년 개정 체육과 교육과정의 개발 및 적용 경험이 있는 총 8명의 연구 참여자들에 대한 인터뷰와 연구저널의 내용을 바탕으로 체육과 교육과정 개발과 적용과정의 경험과 이러한 과정 사이에 내재되어 있는 다양한 형태의 간극 요인과 이에 대한 대응방안을 밝혀내고자 하였다. 간극에 관한 과정별 요인들은 체육과 교육과정 개발과 적용의 전체과정을 ‘연구⋅개발단계’, ‘보완단계’, ‘보급단계’, '수용단계‘, 실행단계’ 등의 5단계로 나누고 각각의 단계에서 발생할 수 있는 간극의 요인을 구체적으로 검토해 나갔으며 이에 대한 각각의 구체적 대응방안을 함께 제시하였는데, 이러한 과정별 요인 분석은 체육과 교육과정의 개발과 적용과정을 ‘총체적 관점’으로 바라보는 가운데 순차적 흐름과 체계성 속에서 간극의 문제를 조망할 수 있도록 하고 있다. This study covers the development process of the National Physical Education(P.E.) Curriculum and its application in many curricula according to city and province offices of education, and various schools and classes based on a holistic view. In order to analyze and understand this narrative inquiry, qualitative research emphasizing the subjects' experiences is used. The purpose of the research is to recognize the diversity and complexity of the process inherent in developing and applying the P.E. curriculum. Through this, the ultimate goal is to pinpoint the disharmony caused by the gaps and its countermeasures in the development and application of the P.E. curriculum following each revision. To achieve the purpose of this study, qualitative research was used on 8 participants who have developed and applied the 7th National P.E. Curriculum and the 2007 revised P.E. Curriculum. The purpose was to identify how the P.E. Curriculum was developed and applied, the causes of the various gaps which occurred between research processes, and to seek a countermeasure as a solution. The conclusions were as follows ; The factors that influence the generation gaps of the P.E. curriculum can be divided into three process factors. the process factor of the generation gap divides the entire process of curricular development and application into five stages: research and development, supplementation, diffusion, adaptation, and implementation. The potential generation gap factors that may occur in each separate stage are well explained. Such an analysis of the process factor makes it possible to anticipate the problems of the generation gap in the regular sequence of the development and application of the P.E. curriculum in a holistic way.
