김형진,이지영,권혁윤 한국공업화학회 2004 응용화학 Vol.8 No.1

This study was carried out to evaluate the application possibility of UF Membrane System to papermaking industry in order to optimize the recycling of white water. In this study, for the efficiency test of UF modules, the MWCO(molecular weight cut-off) of the membrane was estimated by the COD measurement from UF filtrate water. From the rejection rate of membrane, three kinds of UF module were selected and evaluated in the factors of COD, SS, turbidity and flow rate.

This study examined subjective symptoms attacking the musculoskeletal system of insurance inspectors from April 8th to April 30th, 2002, and calculated its attack rate. NIOSH's standardized questionnaire was applied in order to uncover correlative factors, and a structuralized self-administered questionnaire was used to measure general characteristics, duty-related factors, and satisfaction degree on VDT worktable. Two hundred one questionnaires were collected and analyzed into the following outcomes. 1. Subjective symptom rates of musculoskeletal disorder are 74.6% at the shoulder, 62.7% at the neck, 52.7% at the waist, 47.3% at the hand/wrist/fingers, and 36.3% at the arms. 2. Bivariate analysis was conducted on the factors related with subjective symptoms on the musculoskeletal system against the observed factors, and significant relations were found as follows: marital status in general characteristics vs the hand/wrist/fingers; in duty-related factors, the number of working hours per day vs the hand/wrist/fingers, VDT continuous working hours, working speed adjustment vs the neck, and the degree of job-satisfaction vs the waist; in satisfaction degrees of VDT worktable, the height of chairs vs the hand/wrist/fingers, the height of worktable vs the arms, the hand/wrist/fingers, and the waist, the working space on the table vs the neck, and the waist, the space under the worktable vs the waist, the hands' posture on the keyboard vs the neck, the hand/wrist/fingers, and the waist. 3. Correlation analysis was conducted on musculoskeletal disorder symptoms and related-factors: a single person, the long length of working hours per day vs the hand/wrist/fingers, long length of VDT working hours vs the neck, in a state of rest, and in working speed adjustment vs the neck, in the case of being dissatisfied with work vs the waist, and in the case of being dissatisfied with the VDT worktable vs the neck, the arms, and the hand/wrist/fingers showed statistically significant differences. 4. Logistic regression analysis was conducted to uncover correlative factors with the musculoskeletal disorder symptoms; the working hours per day, and the height of chair significantly affected the neck; the working hours per day affected the shoulders; the height of table affected the arms; the degree of job-satisfaction, VDT continuous working hours, and the space under the worktable affected the waist. As shown above, insurance inspectors should consider working hours per day, VDT continuous working hours, and resting time, in order to prevent musculoskeletal disorder symptoms rate by body parts, and ergomechanic and biomechanical conditions related with chairs and tables should also be considered in order to prevent musculoskeletal disorder symptoms.

속도추정기를 이용한 3상유도전동기의 센서리스 속도제어에 관한 연구

정주윤,권형정 동의공업대학 2000 論文集 Vol.26 No.1

Several methods of induction motor drives, which use speed estimators instead of shaft encoders, have been reported. However, the characteristics of the vector control employing stator voltages and currents usually deteriorate as the speed gets lower because it is difficult to calculate rotor flux due to de-offset and saturation of integrators. In this paper, to make it possible to calculate rotor flux at standstill, the new rotor flux estimator which replace integrators with two lag circuits is proposed. Simulation and experiment results confirm the validity of this control scheme.

The Purpose of this study was to utilize of CAD System in pattern making process for women's apparel. The automation by the use of CAD System provides the higher accuracy and efficiency in pattern making process. AccuMark 300 System was used, for this study. The results from this study were as follows 1. New size spec chart and grading pitch chart were developed based on the data analysis and fitting tests for female college students. 2. New jacket block was developed based on the torso length sloper. 3. Automatic grading of jacket block have been developed by creation and modification of grading rules of block pattern. 4. Pattern Design Systyem(P/D/S) were enabled to be constructed directly form a block pattern by modifications to existing styled pattern. 5. Original master pattern was generated by P/D/S menu option. 6. Production pattern added seam allowance, notchs was generated by P/D/S menu option. 7. Interative maker making process have enabled to save a wide range of time and space. 8. Measurement of garment by P/D/S measuring tools is to utilize in garment costing, quality control.

어패럴 CAD System의 활용화 방안 연구(Ⅰ) : Hip Block 의 개발

남윤자,이형숙,조영아 한국의류학회 1993 한국의류학회지 Vol.17 No.4

The Purpose of this study was to develop pattern drafting methods of the hip block and sleeve for female college students of 18 to 26 year-old. The study procedures and results were as follows 1. 313 female college students were measured, 17items were analyzed statisitcally. 2. New hip block and sleeve sloper were developed based on the result of the data analysis and fitting tests. 3. The sensory test was applied to evaluate the new hip block and sleeve sloper for female college student by comparing it with Japanese Bunka method sloper. According to statistical analysis of the result of 40items on the questionnaire, all the items showed significant difference(a∠=0.01) between the two, with the new pattern having higher scores. The new drafting method proved to be better fitted at all 40items, and to be comfortable.

Purpose: The proportion of centenarians has been increasing in many parts of the world, and the issues of longevity has been the subject of the research concern in recent years. We has conducted the first study with centenarians in Busan, 2006 and this is a follow-up study for prospective research of centenarians in Busan. Methods: The demographic database of Busan Centenarian Study existing in 2006 wasutilized for our studies. Twenty-five centenarians or a proxy were contacted and eight individuals agreed to have a direct interview using a questionnaire. Data were collected from May to June 2007. Results: Of the 2Scentenarians, 2(8%)were men and 23(92 %) were women. The average age was 101.3 years and the highest one was 106 years of age. The majority of the centenarians were living with family, most of those were living with their sons. Among 8 visited centenarians, there were 2 drinkers(2S%) but no one was smoking. Among them, 7 centenarians (87.5%) had regular eating pattern and, 3 centenarians(37.5%) participated social activities. Conclusions: The centenarian in Busan is likely to be healthy and they are living with their family. The centenarians study in Busan has important meaning to understand the health of centenarians.

Proximate analysis, mineral and fatty acid composition of three conventional domestic soybean cultivars and two imported ones including glyphosate-tolerant HS2906 were evaluated by AOAC method, ICP-AES and gas chromatography. There were several differences in the proximate analysis among three conventional domestic soybean cultivars ; higher crude fat in the cultivar Hwanggumkong, higher crude protein in Pungsankong, and higher carbohydrate and crude ash in Duyukong. The ranges of contents of proximate components of domestic cultivars were similar to the data previously reported. There were no significant differences in proximate analysis between conventional soybean WS82 and glyphosate-tolerant HS2906 ; 23.55~23.90% of crudefat, 34.22~35.55% of crude protein, 6.25~6.45% of crude ash, and 25.35~26.47% of carbohydrate. The mineral and fatty acid compositions of HS2906 were similar to those of conventional soybeans previously reported.
