This report outlines a ten-year(1976-1986) academic and physical development plan of Jeonbug National University. It was prepared over a period of ten months from April, 1976, to February, 1977, by a committee of five professors under the supervision of Dr. Chong Soon Lee. For a final report, the committee not only reviewed the past trend and patterns in the University's development and its present structures and conditions, both academic and physical, but also constantly consulted with Dr. Chong Supp Shim, president, the faculty, and experts in the field through meetings and questionaires. Consultation with them was paticularly needed in envisioning the future directions and possibilities for developing the University. The report presented here is a version revised and approved by the deans council of the University. Since its foundation in 1951, Jeonbug National University has grown from a small provincial institution into a full-scale national university. It now comprises seven colleges and three graduate schools, the students currently enrolled numbering around 5,500 and the faculty and administrative staff consisting of 750 employees. In keeping with the rapid growth of the nation and the governmental emphasis on developing provincial universities, the University is expected within ten years to develop into an academic institution consisting of eight colleges and six graduate schools. The number of undergraduate departments will increase from 40 to 61, and the number of students in attendance will amount to 10,000. In order to cope with this rapid increase in the number of departments and students, the academic plan of this report preseents a time-table of setting up new departments and makes a proposal for restructuring the University's academic and administrative systems. It also recommends that with the inception of the Research Foundation research activities will be systemitized and coordinated around ten major research institutes at the University. The physical development plan of the University has been in urgent need. The planning committe laid out a road construction plan mapping the entrances and major traffic routes on the campus. It also made proposals as to future building sites, centering around the central library under construction. The Medical School and its hospital, now in downtown Jeonju, are planned to be built on the 2nd campus east of the main campus. The University High School is also planned to move to the eastern part of the main campus. Besides the further construction of classroom and laboratory buildings, the University plans to construct an auditorium, an audio-visual center, a museum, a gymnasium, a new administration building, and other facilities. For the completion of these buildings, the estimated cost will amount to 200 billion won in total.

Although fruit production and consumption have been increased by the improvement of national income and the changing of food request, those of processed fruits have been more increased. Nowadays, the importing amount of processed fruits is three of four times as much as exporting amount of processed fruits in the amount of quantity and money, and it is expected that the import of cheaper foreign-processed goods will be sharply increased by the set out of WTO(world trade organization) through UR conversation. Therefore, for domestic market, the competitive power should be developed by the curtailing the productive cost through the usage of unmarketable fruits and cheaper materials, prolongation and automation of packing factory, by the fruit quality improvement for consumer's taste, and by the governmental support such as facility fund. For foreign market, the exporting condition must be improved by the enlightenment of processed goods suitable for foreigner's taste and enlargement of importing countries.

In this study, the diameters and depths of the intial surface crack configuration on the specimen was discharge processed differently and considered about propagation behavior and fatigue lifetime of the surface fatigue crack in each case. The result of this study are Summerized as follow; 1. Under the given constant condition, aspect ratio is regular in surface crack propagation, and early its differenceis large according to the initial surface crack configuration but it shows the same change aspect according to the propagation of the crack. 2. In general, for constand initial crack depths we may expect that initial crack lifetime is increased as diameter of specimen is increased because of relaxation of the stress concentration. Practically, however it is different according to the crack. 3. Early, Surface crack configuration has semi-circle and it has semi-elliptical according to crack propagation. 4. When the initial surface crack aspect ratio is in the range of 5∼6, the initial surface crack is propagated to inner surface under the condition, which ratio is smaller than the range. In the ratio is lager than that range, crack is propagated to outer surface.

The role of Pseudomonas aeruginosa in human diseases has received increasing attention in recent years. There is considerable evidence that intestinal Gram negative bacillary infections are occuring with greater frequency. Among these bacilli, Ps. "aeruginosa is so notoriously resistant to many antibiotics that it occupies an almost unique position. 903 strains of Ps. aeruginosa were isolated from various clinical materials at Seoul National University Hospital during the period of January 1st, 1970 and December 31. 1974 and clinico-bacteriological studies were made. The results were summarized as follow. 1. Clinical materials, from which Ps. aeruginosa were isolated, were Pus 448, Urine 151, Sputum 142, Throat swab 34, Blood 33, Bile 20, Bronchial aspiration 10, Pleural fluid 8, Stool 8, Spinal fluid 4, Vaginal discharge 2, Bone irrigation 2 and Ascitic fluid 1, respectively. 2.

MnO_4^--(COOH)_2 redox system에 의해 개시된 methyl methacrylate의 중합을 질소 분위기에서 35±0.2℃의 aqueous media내에서 연구하였다. 중합속도는 낮은 활성제 농도(2.0×10^-3-7.5×10^-3M)에는 무관하지만 그 이상의 높은 농도에서는 속도가 감소함을 알 수 있었다. 중합의 개시속도는 낮은 촉매농도(0.5×10^-5-2.0×10^-5M)에서는 반응차수가 1차이었으며 높은 촉매 농도(4.0×10^-5-3.2×10^-4M)에서는 대략 0.5차 임을 알았다. 또한 개시속도는 낮은 단량체 농도(2.0×10^-2-10.4×10^-2M)에서는 비례하여 증가하나 10.4×10^-2M농도 이상에서는 오히려 감소하였다. 온도가 30∼45℃ 범위 내에서는 온도가 상승함에 따라 개시속도는 증가하지만 최대 중합율은 감소하였고, 25∼45℃의 온도 범위에서 총괄 활성화 에너지는 8.2Kcal/mole임을 알았다. 유기용매인 알콜과 Salts의 첨가는 중합속도를 감소시켰으나 MnSO_4는 개시속도를 증가시키는 반면에 EDTA는 최대 중합율을 상당히 증가시켰다. 그리고 FeCl_3·6H_2O와 CuCi_2·2H_2O는 중합 억제력이 아주 크다는 것을 알 수 있었다. The polymerization of methyl methacrylate initiated by permanganate-oxalic acid redox pair has been studied in aqueous media at 35±0.2℃ in nitrogen atmosphere. The rate of polymerization is independent of activator concentration (2.0×10^-3 to 7.5×10^-3M), but the further increase of the concentration decrease the rate. The initial rate of polymerization has been found to be proportional to nearly the first power of low catalyst concentration (0.5×10^-5 to 2.0×10^-5M) and 0.55 power of high catalyst concentration (4.0×10^-5 to 3.2×10^-4M). The initial rate increases linearly at low monomer concentration (2.0×10^-2 to 10.4×10^-2M) but decreases at higher monomer concentration (above 10.4×10^-2M). The initial rate increases as the temprature increases from 30℃ to 45℃, while the maximum conversion decreases. The overall energy of activation has been found to be about 8.2 Kcal/mole within the temperature range 25-45℃. Organic solvent (alcohols) and salt (KCI) decrease the rate of polymerization but MnSO_5 increases the initial rate and complexing agent EDTA increases the maximum conversion to a considerable extent. FeCl_3·6H_2O and CuCi_2·2H_2O have been found to be polymerization retarders.

SCR용 외부혼합형 이유체 노즐개발을 위한 실험적 연구

이영진,박종원,이충원,석지권 朝鮮大學校 機械技術硏究所 2005 機械技術硏究 Vol.8 No.1

소각로 내에서 생성되는 질소 산화물을 저감시키는 SCR 설비의 핵심 기술이 되는 분사 노즐의 특성을 분석하고자 두 유체가 지나는 통로에 선회기가 달린 외부혼합형 이유체 노즐을 선정하여 물과 공기의 유량 및 압력 변화를 주었으며 외부노즐의 오리피스 직경의 변화와 두 노즐 선단부의 상대적인 변화를 주었다. 이와 같은 외부 혼합형 이유체 노즐의 장점은 다른 종류의 노즐을 사용할 때보다 더욱 미세한 액적을 얻을 수 있으며 액체의 유량이 변해도 일정한 형태의 분무각을 유지시켜 준다. 또한 액체의 압력이 기체의 압력보다 높은 경우에도 액체노즐에서 분사되는 액적이 기체 공급관으로 역류하는 일이 없으며, 기체의 압력이 액체의 압력보다 높아도 액체의 분사특성에 거의 영향을 주지 않는다. 그리고 공기가 선회기를 지나서 분사되기 때문에 더욱 활발한 와류가 생성된다. 따라서 분사 액적과 공기와의 혼합이 더욱 잘 이루어지리라 예상된다. 또한 거의 모든 분사압력범위에서 미립화가 잘 이루어지기 때문에 저압에서 고압으로 압력에 따른 분무 특성을 연구하기에도 적합하며 점도가 있는 물질의 분사에 특히 유효하므로 SCR 설비에 적합한 노즐로 사료된다. The effect of the working fluid flow conditions and nozzle geometry on the spray performances of a twin-fluid nozzle used in SCR(Selective Catalytic Reduction) is investigated experimentally. In this experiments, the liquid pressure is varied in the range of 0.3atm to 1.5atm and the annular air pressure is varied from the 0.5atm to 3.0atm. Relative position between liquid and air outlet port changes from 1mm inside the nozzle cap to 1mm outside the nozzle cap. The outer diameter of the air outlet port is varied with 5mm, 6mm and 7mm. Spray visualization is realized with CCD-Camera. SMD(Sauter Mean Diameter) and mean particle velocities are measured by PDPA(Phase Doppler Particle Analyzer) under various experimental conditions. The measuring point is 300mm away from the nozzle tip in the downstream spray. The experimental results are that spray angle is depended Air flow rate because Nozzle diameter, air pressure and nozzle tips relative position(nozzle tip) are related air flow rate. Also, SMD(sauter mean diameter) is depended Air flow rate and Water flow rate. SMD is increased when Water flow ratetwater pressure) is bigger. But SMD is decreased when Air flow rate (Air pressure) is bigger.
