A study was performed on knowledge and attitude of women students of University on population and family planning. The study group consisted of 229 students of Jeonbug National University who took a course of Population Education, and the control group was the students of Woo Suk College who did not take the course. The major findings and results are summarized as follows: Ⅰ. The knowledge and responses measured on population and family planning, between the study group and control group were not different significantly. Ⅱ. The family planning was pointed as the best means of solution over population problems. Ⅲ. On the ideal age of marriage, the mean was 24.96 ± 1.19 years in study group, and 24.65±1.36 years in control group. Ⅳ. The mean age desired for marriage was 26.42 ± 1.61 years in study group, and 26,30±1.69 in control group, The diference between two groups was not significant. Ⅴ. The ideal age of the first child birth was 26.70 ± 3.89 years in study group and 26.34±3.66 years in control group. Ⅵ. The mean number of children desired was 1.54 ± 0.94 years in study group and 1.78 ± 0.92 years in control group. The difference between two groups was slightly significant. Ⅶ. The attitude of control group on sterility was more conservative than study group. The control group showed more interest in adoptation of children than the study group. Ⅷ. To compare with the general population on preference of boy, both of the study group and control group showed less interest in the preference of boy. However, 3.5 per cent of the study group studdkents had of study group. The difference between two groups were significant statistically. Opinions to keep trying till a boy is born. The more students of control group prefer boy to girls than those of study group. The difference be tween two groups were significant statistically. Ⅸ. More students of control group consider children means of keeping family generation than those of the study group. Ⅹ. Out of the total, 80 per cent of the study group had knowledge or pregnancy, and physiology of birth. mean while 66 per cent of the control group had knowledge on those areas. A. The mean number of family planning methods pointed out by study group studdkents was 4.5± 2.1, and material of family planning(22.7%), and TV and radio(19.7%). Menawhile, the sources given by the Control group. B. The sources of information of family planning answered by the study group were school (40.2%), education material of family planning (22.7%), and TV and radio (19.7%) Meanwhile, the sources given by the control group were educational material (28.2%), TV and radio (25.9%) and school (24.5%). C. On the responses of the study group students on time allocation on population education, 66.8% of them had the opinions that the time allocated was adequate, 26.6% having opinions that the time was not adequate, and 6.6% having opinions that the time was more than enough. D. The evaluations made by the study group students on the level of population education were as follows 65.9% of the students consider the level to be adequate, 30.2% considering the level to be low, and 3.9% considering the level to be difficult. E. Out of the total, 55.0% of the study group students were satisfied with the contents of porplation education program and 22.7% were very satisfid the contents and 19.2% were not satisfied with the contents of the program.
산소부화 조건에서의 하수슬러지 연료탄의 연소 용융 특성 연구

국내 공공 하수처리시설 569개소에서 2017년 기준 11,415톤/일의 하수슬러지가 발생하고 있으며, 과거 해양투기에 의존하였던 하수슬러지 처리는 2012년 이후 해양투기가 전면 금지됨에 따라 슬러지의 순환자원화로 정책방향이 전환되고 있다. 일반적으로 하수슬러지는 전처리 후 혐기성 소화, 열분해, 가스화를 통해 Bio-gas, Bio-char, Bio-oil, 합성가스 등의 연료로 전환하거나 연소를 통해 열에너지 및 전기에너지로 전환될 수 있다. 하수슬러지는 건조, 성형 과정을 거쳐 약 3,000 kcal/kg 정도의 열량을 가진 연료로 전환될 수 있다. 하수슬러지 연료탄은 회분함량이 높아 연소 후 바닥재와 비산재의 발생량이 많아 적정 처리하지 않을 경우 환경적인 문제를 야기할 수 있으며, 또한 최근 소각 비산재의 처리비용 상승으로 인해서 운영업체에게 경제적으로 부담스러운 상황이다. 하수슬러지 연소 시 발생되는 소각재를 안정적으로 처리하기 위한 대안으로 연소 용융기술이 가장 안정적인 기술이지만 1,400℃ 이상의 반응온도 유지를 위한 높은 운전비로 상용화에 한계가 있는 것이 현실이다. 본 연구에서는 하수슬러지 연료탄의 연소 용융에 있어서 하수슬러지 연료탄의 발열량 증진 및 글루존 회피를 위해 첨가되는 톱밥의 영향을 랩실험을 통해 살펴본 후 파일럿 플랜트에서의 산소부화에 따른 하수슬러지연료탄의 연소 용융 특성을 살펴보았다.

The chemical kinetics of the steam reforming of the pyrolysis oil of polypropylene (PP) over a ruthenium-based catalysthas been examined as a function of pyrolysis oil and steam partial pressures at various temperatures. The activation energyof steam reforming over Ru/Al2O3 catalyst is 136 kJ/mol, and the reaction orders of pyrolysis oil and steam are 0.42and 0.24, respectively. Fitting the experimental data to the Langmuir?Hinshelwood expression shows that the steamreformingreaction probably proceeds via the dissociative adsorption of pyrolysis oil and steam on two different sites.
