The purpose of this study was to make an short form of K-WAIS for patients with organic mental disorder due to head trauma. The patients were 215 brain damage patients with organic mental disorder whose sex were composed of 160 male and 55 female. The new form consisted of comprehension, vocabulary, picture completion, and picture arrangement. Multiple correlation coefficient(R=.81) with Full IQ was higher than that of the existing short-form and could explain 66%. This result suggested that K-WAIS short-form was enable to estimate IQ for patients with organic mental disorder due to head trauma.

The purposes of this research were constructed the database, based on graphing the present water pollution in Han-river due to livestock wastewater(LSW). The LSW was below 1% in respect to quantity but about 7% in respect to pollutions loading in overall Han-river. The ratio of untreated LSW is 18% to 28%, which was higher compared to the municipal and industrial wastewater. In other words, LSW was about 0.05 times of municipal wastewater in respects to quantity but 2 times in respect to the ratio of untreated wastewater. So, it was necessary for treating LSW. The pollutions loading due to livestock wastewater of the South Han-river. North Han-river and main stream were 19.7%, 19.4% and 4.0%, respectively. This was about 7% in overall Han-river. We separated the Han-river into upper, mid and down stream. As a result, we found that the livestock wastewater is the main water pollution source of upper Han-river.

In urban area, thermal pollution associated with heat island phenomena is generally regarded to make urban life uncomfortable. To overcome this urban thermal pollution problem, urban planning with consideration of urban climate, represented by the concept of urban ventilation lane, is widely practiced in many countries. In this study, the prevailing wind ventilation lane of a local winds in Daegu during the warm climate season was investigated by using surface wind data and RAMS(Reasonal Atmospheric Model System) simulation. The domain of interest is the vicinity of Daegu metropolitan city(about 900 km²) and its horizontal scale is about 30km. The simulations were conducted under the synoptic condition of late spring with the weak gradient wind and mostly clear sky. From the numerical simulations, the following two major conclusions were obtained: (1)The major wind passages of the local circulation wind generated by radiative cooling over the mountains(Mt. Palgong and Mt. Ap) are found. The winds blow down along the valley axis over the eastern part of the Daegu area as a gravity flow during nighttime. (2)After that time, the winds blow toward the western part of Daegu through the city center. As the result, the higher temperature region appears over the western part of Daegu metropolitan area.

비파열성 뇌동맥류의 수술과 연관된 합병증

구희상,강성돈 원광대학교 의과학연구소 2009 圓光醫科學 Vol.24 No.1

비파열성 뇌내 동맥류의 크기, 위치, 환자의 나이에 따라 치료결정에 대한 논란이 많으나 적극적인 치료가 증가 추세이다. 문헌상 파열성 뇌내 동맥류보다 수술 합병증의 빈도는 덜하지만, 새로운 뇌경색이나 수술 부위와 떨어진 소뇌의 출혈과 같은 예기치 못한 합병증이 보고되고 있다. 비파열성 뇌내 동맥류는 수술 전에 증상이 없거나 심각하지 않으므로 수술이 더 용이하다고 해서 쉽게 생각하는 것은 절대 금물이고, 보호자에서 충분한 사전 설명과 함께 위험성과 효율과의 비율을 정확히 고려해야 할 것이다. Background: With advances in neuroimaging, unruptured cerebral aneurysms are being diagnosed more frequently. Surgery is warranted if surgical risk are less than the risk of natural history. In this study, we investigated the surgery related complications and its prognosis after clipping of unruptured cerebral aneurysms. Methods: The study consists of a retrospective review of 100 patients who underwent surgery performed by one surgeon for 110 unruptured aneurysms between January, 1990 and December, 2006. One hundred and two aneurysms(92.7%) were successfully clipped, and 8(6.4%) were either wapped or trapped. The clinical outcomes were evaluated in each patient by the Glasgow Outcome Scale at discharge. Results: Thirty(30%) of the patients were asymptomatic, while the remainder(70%) had various symptoms. Regarding the aneurysmal size, 4(3.6%) were giant aneurysms, and 88(80%) were small aneurysms less than 10mm in diameter. The location of the aneurysms were internal carotid artery, middle cerebral artery, anterior cerebral artery in order of frequency. Ninety eight patients recovered without any neurological deficits. A procedure-related surgical complication was diagnosed in 2 cases(2%). Complications included hemiparesis(moderately disabled) following cerebral infarction. Conclusion: The morbidity rate associated with treating unruptured aneurysms is not negligible with increasing trend of active management decision in patients with unruptured aneurysms. Treatment requires accurate assessment of the risk/benefit ratio considering natural history of the disease, and unpredictable complication ratio should be closely monitored.

E. coli A_2 diarrhea causing bacteria of pigs was anaerobically inoculated with 10^5/ml into prereduced YS medium (10% reconstituted skim milk+0.1% yeast extract), and then lactic acid bacteria were inoculated with 10^5/ml and 10^7ml into previous inoculated samples of E. coli A_2. Inoculated samples cultured at 37℃, were tested to determine changes in viable numbers of organisms and pH. The experimental results are summerized as follows: 1. In the mixed culture medium of 10^5/ml E. coli A_2 and L. casei YIT9018, E. coli A_2 decreased after 36 hours from incubation. 2. In the mixed culture medium of 10^5/ml E. coli A_2 and L. acidophilus, E. coli A_2 drastically decreased after 24 hours from incubation and was almost disappeared after 72 hours from incubation. 3. In the mixed culture medium of 10^5/ml E. coli A_2 and L. bulgaricus, E. coif A_2 drastically decreased after 24 hours from incubation and was almost disappeared after 72 hours from incubation. 4. In the mixed culture medium of 10^5/ml E. coli A_2 and Str. thermophilus, E. coli A_2 decreased after 12 hours from incubation. 5. When the pH value of the mixed culture, was, 4. 5 below, E. coli A_2 decreased.

An experimental study was designed to analyze the surface reduction effect of ultrapulse carbon dioxide laser on the skin of guinea pigs receiving laser resurfacing. Two squares of skin measuring 3x3 ㎠ were designed on each side of the abdomen of guinea pigs(n=10). Five animals received laser resurfacing on their abdomen at energy of 250mJ/5 watt, and five other animals received 500 mJ/5 watt. On each animal, the left side square was treated with one pass of a CO2 laser, and the right side q=square was treated with two passes using a C.P.G. scanner. The size of the resurfacing area was determined by celluloid overlays at 1,2,3,4 and 6 weeks. Immediately following laser resurfacing, the area was decreased to 69%(left side) and 56%(right side) of the designed area in the 250 mJ/5 watt group, and 59% and 40% in the 500mJ/5 watt group. After 6 weeks, the resurfaced area had been reduced to 70% and 56% of the designed area in the 250mJ/5 watt group, and 60% and 40% in the 500mJ/5 watt group. As a result, the effect of surface reduction by CO2 laser resurfacing increased at a higher power and when more passes of the ultrapulse carbon dioxide laser were applied. The laser treated skin continued to maintain its contracted dimensions. These findings suggest that ultrapulse carbon dioxide laser may be an effective treatment method for rhytides. Another experiment was performed on multiple punch-out lesions on guinea pig skin(n=2) with 1,2,3 mm collimated hand pieces for the purpose of determining a new laser treatment method. After 4 weeks, on gross and histological examination, there were no differences in the healing of multiple punch-out lesions and the healing of punch-out lesions was complete without any scarring. These findings suggest that the laser punch-out method can be used for the treatment of acne scars.
