Diesel engines which emit a lot of PM and NOx have been known as a main air polluter. Especially, diesel particulate matters (DPM) including black smoke are hazardous air pollutants to human health and environment. The nations retaining advanced engine technologies have reinforced emission regulations. To meet these regulations diesel engine manufacturers have developed low-emission diesel engines, aftertreatment equipments, alternative fuel technologies and so on. In this study, particle number concentrations characteristics according to particle size and engine driving conditions were analyzed when these low-emission technologies were applied. There was a tendency of increasing particle number concentrations from heavy-duty diesel engines with increasing engine rpm and load rate. In the cases of CDPF (Catalytic Diesel Particulate Filter), CNG (Compressed Natural Gas) engine and ULSD (Ultra Low Sulfur Diesel) more than 99% of particle number concentration were removed.

This study was intended to analyze the vocational education curriculum based on the job status of people with disabilities. For this purpose, secondary data from statistical data of 'survey of the disabled employment reality - in-depth survey' implemented by Korea Employment Agency for the Disabled were used to reveal the job status of people with disabilities. In addition, vocational education curriculum of three special schools was analyzed. In this study, following issues are suggested. First, vocational education for students with intellectual disabilities should focus the adaption ability at working sites and provide field oriented education which is for enhancing job skills. Second, by emphasizing working site-based education, an opportunity of being able to apply occupational skill and knowledge obtained with an aim of responsible duty performance and achievement of duty goals that are required at working sites should be provided diversly. Third, in order to share an information for man-recruit as well as job-seeking between school and the job sites efficiently, a communication channel is required in a governmental perspective. 본 연구는 장애인 근로자의 직업의 실태와 직업현장에서 요구하는 요구사항을 분석하고, 특수학교에서 운영되고 있는 기본교육과정 직업교과와 전공과 교육과정을 비교하여 연계성을 찾고 이를 통해 문제점을 도출하여 정신지체학생의 직업교육의 방안을 제시하고자 하는데 그 목적이 있다. 본 연구를 위하여 한국고용공단에서 실시한 장애인 고용실태의 자료의 일부를 활용하였고, 3개의 정신지체 특수학교의 직업교육 및 전공과 교육과정이 분석되었다. 연구 결과를 종합하여 보면 현재 운영 되고 있는 정신지체 특수학교 직업 교육과정은 학교 선택 직종과 취업 현장의 직무는 연계성은 있으나 취업 전형, 사업체에서 필요로 하는 신체적 기능, 직무 능력, 업무 수행능력 등과 관련된 교육 내용이 적은 것으로 나타났다. 따라서 정신지체 직업 교육은 정신지체인의 직업 현장 적응력을 높이고 사업체의 장애인 근로자에 대한 만족을 높일 수 있도록 직업 영역과 제재를 포함하고 관련된 지식과 기능을 늘릴 수 있도록 시수 등을 보강하는 노력을 해야 할 것이다. 또한 학교와 사업체 간의 구인과 구직에 관한 정보를 효율적으로 공유할 수 있도록 정부적인 측면에서 의사소통의 장이 필요하다. 끝으로 연구의 제한점과 후속연구에 대한 제언이 포함되었다.

The effects of charcoal powder on fermentation of dough and quality of bread were investigated. Charcoal powder was added to wheat flour at concentrations of 0, 0.05, 0.10 and 0.20%. The fermentation time of dough with charcoal was reduced by 4~12 min compared with that of dough without charcoal. The loaf volume index of bread with 0.05% charcoal powder slightly increased. Bread with charcoal powder showed higher textural properties (strength, hardness, springness, gumminess, and brittleness) except for cohesiveness than bread without charcoal powder. Color L^(*) and b^(*) values and hue angle of the top crust decreased while a^(*) value increased with increasing charcoal concentrations. L^(*) and a^(*) values of the inside of bread decreased while hue angle increased with increasing charcoal concentrations. No significant difference in pleasant taste between bread with and without charcoal powder was observed. However, bread with 0.1% charcoal powder showed the highest scores for pleasant odor, color, and overall acceptability.

The purpose of this study was to evaluate the change of lumbar lordosis before and after pedicle screw fixation. Authors analyzed the change of lumbar lordosis in 100 cases of degenerative spinal stenosis, which were operated on using pedicle screws from January 1994 to July 1996. We also measured the total lordosis angle(TLA) and segmental lordosis angle(SLA) according to the fusion types and the fusion segments. Total lumbar lordosis angle was measured from the upper endplate of the first lumbar vertebra to the upper endplatee of the first sacral vertebra. And the segmental lordosis angle was measured from the upper endplate of the upper-most vertebra in fusion segments to the upper endplate of the lower-most vertebra. In all patients, mean TLA was 33.6 degrees preoperatively, 37.9 degrees postoperatively and 36.1 degrees in last follow-up. The TLA according to fusion types mostly change in the six and seven decades of two groups (floating, fixed fusion group). The TLA and the SLA according to fusion segments mostly changed in 5 segments fusion group and the change according to fusion types was not. In pedicle screw fixation, physiologic lordosis can be maintained by using the four-poster frame. Preoperative hypolordosis can be corrected into physiologic lordosis by pre-bending technique of the rod. But excessive pre-bending of the rod for correction of the lordosis increased the possibility of loosening of the sacral screws.

Eight monitoring stations in the Yeosu National Industrial Complex will determine the concentration of air pollutants measured every hour in 2019, analyze what factors affect them, and how they correlate with the air pollutant measurements. Six air pollutants (SO2, NO2, O3, CO, PM-10 and PM-2.5) measured at eight monitoring stations around Yeosu National Industrial Complex (Seogang-dong, Wolnae-dong, Munsu-dong, Yeocheon-dong, Deokchung-dong, Hwayang-myeon, Yulchon-myeon, Samil-dong) the measurement data for each hour of the year were downloaded to analyze the concentration by weather condition, time zone, season, separation distance from Yeosu Industrial Complex, and separation distance from Gwangyang Industrial Complex. SO2, NO2, and CO concentrations were significantly higher in winter, significantly lower in summer, and O3, PM-10, and PM-2.5 concentrations were significantly higher in spring. SO2, CO, PM-10, and PM-2.5 concentrations were significantly higher between 10 a.m. and 12 p.m., NO2 concentrations were significantly higher between 7 a.m. and 9 a.m., and O3 concentrations were significantly higher between 13 p.m. and 15 p.m.(p<0.001). The concentration of air pollutants (SO2, NO2, CO, PM-10, PM-2.5) excluding O3 was found to have a negative (-) correlation with weather condition, and in the case of O3, it was found to have a positive (+) correlation with PM-10, PM-2.5, temperature and wind speed. It was confirmed that the concentration of air pollutants emitted from the Yeosu National Industrial Complex differs depending on the season, time and distance to the industrial complex. This study aims to establish measures to minimize health damage to residents living relatively close to the industrial complex and contribute to the establishment of management and response measures according to the properties of substances to reduce the concentration of air pollutants in the future.

This experiment was carried out to investigate the effects of overhead irrigation of Ethrel on after-ripening of kiwi fruit, and to improve marketability and decrease operating cost as to ripen kiwi fruit at the stage of consumption. In 1994, the eight-year-old Hayward which were planted in farm field at Haenam Okchen were treated with 100ppm, 150ppm and 200ppm overhead irrigation of ethephon on September 25, September 30 and October 5 respectively. In 1995, the nine-year-old Hayward which were planted in windbreak net house at Moonlae Haenam were treated with 40, 70 and 100ppm overhead irrigation of Ethephon on October 5, October 10 and October 15 respectively. As the result of at 10 and 20 days after treatment, in 1994, the firmness was much low as to show 0.8 to 0.95kg at 10 days after treatment, 0.2 to 0.33kg at 20 days after treatment. And sduble solid content was 10.6 to 11.7˚ Bx and abscission rate was 10.3 to 35.9%. Therefore, the marketability were tended to be showed low. In 1995, as that firmness was 3.2 to 3.7kg, last soluble solid content after harvesting was 13.8 to 14.0˚ Bx and abscission rate was 0%, there was no problems in marketability and marketing. Therefore, this results were demonstrated that the treatment after October 10 in 70 to 100ppm ethephon can be improved marketability and marketing of kiwifruit.

Purpose: The purpose of this study was to understand the degree of depression, sleep quality, job stress and their association among office workers. Method: A self-administered questionnaire was distributed to 147 workers employed in 5 big enterprises, and 5 small and medium enterprises from October 21 to November 21, 2012. The questionnaires included socio-demographic and health-related characteristics, job-related characteristics, sleep quality, job stress (KOSS) and depression (CES-D). Result: Among all subjects, 23.1% was in the depression group (21 points and over in the CES-D score). Depressive level was positively correlated with job stress and quality of sleep. The adjusted odd ratio for the effects of sleep quality and job stress on depression significantly increased in the depression group compared to that of the normal group. Multiple regression analysis revealed that the following factors of influence had combined explanatory powers on depression: BMI, life satisfaction, quality of sleep, and job stress. Conclusion: The study revealed that complicated influences were exerted on the level of depression by variable factors, as well as socio-demographic characteristics, health-related characteristics, quality of sleep, and job stress. Specifically, the level of depression was influenced by the quality of sleep and job stress.

Background: Plasminogen activator inhibitor type 1 (PAI-1), an important regulator of plasminogen activator system which controls degradation of extracellular membrane and progression of tumor cells, and PAI-1 gene polymorphic variants have been known as the prognostic biomarkers of non-small cell lung cancer patients. Recently, experimental in vitro study revealed that transforming growth factor-${\beta}1$ initiated PAI-1 transcription through epithelial growth factor receptor (EGFR) signaling pathway. However, there is little clinical evidence on the association between PAI-1 A15T gene polymorphism and prognosis of Korean population with pulmonary adenocarcinoma and the influence of activating mutation of EGFR kinase domain. Methods: We retrospectively reviewed the medical records of 171 patients who were diagnosed with pulmonary adenocarcinoma and undergone EGFR mutation analysis from 1995 through 2009. Results: In all patients with pulmonary adenocarcinoma, there was no significant association between PAI-1 A15T polymorphic variants and prognosis for overall survival. However, further subgroup analysis showed that the group with AG/AA genotype had a shorter 3-year survival time than the group with GG genotype in patients with EGFR mutant-type pulmonary adenocarcinoma (mean survival time, 24.9 months vs. 32.5 months, respectively; p=0.015). In multivariate analysis of 3-year survival for patients with pulmonary adenocarcinoma harboring mutant-type EGFR, the AG/AA genotype carriers had poorer prognosis than the GG genotype carriers (hazard ratio, 7.729; 95% confidence interval, 1.414-42.250; p=0.018). Conclusion: According to our study of Korean population with pulmonary adenocarcinoma, AG/AA genotype of PAI-1 A15T would be a significant predictor of poor short-term survival in patients with pulmonary adenocarcinoma harboring mutant-type EGFR.
