Gastritis cystica profunda (GCP) is a disease characterized by hyperplastic and significant extension of cystic dilatation of the gastric mucous glands, which results in a cystic lesion in gastric submucosa. It often occurs on the part of gastroenterostomy, but can be found in the stomach without any previous surgery. GCP has variable gross finding including solitary polyps, diffuse ones, submucosal tumors, and rare giant gastric mucosal fold. It is difficult to tell GCP from a cancerous lesion by gross finding that the disease demands a necessary tissue biopsy, though GCP is commonly showed as a benign in the progress. We report a case of GCP in polypoid types diagnosed by endoscopic polypectomy.

Severe head injury is associated with a stress response that includes hyperglycemia, which has been shown to worse outcome during cerebral ischemia. To better define the relationship between head injury and hyperglycemia, admission glucose level were analyzed in 150 head injured patients from January 1995 to December 1995. Our retrospective study demonstrated a higher glucose level in patients with low Glasgow Coma Scale(GCS) score, especially at 3-5 GCS score, compared to those with high GCS scores. Also a higher glucose level was noted in patients with vegetative state and dead than in those with good recovery and moderate disability. Hyperglycemia(serum glucose level≥200mg%) was associated with decreased level of consciousness and a poor outcome. We conclude that admission hyperglycemia is a significant indicator of severity of injury(p<0.001), but not significant predictor outcome from head injury. After controlling for the influence of the GCS score, glucose levels do not have an independent effect on outcome.

Gastric angiodysplasia is vascular ectasia in mucosa and submucosa of the gastric wall. It is an uncommon cause of upper gastrointesinal hemorrhage that may occur in the stomach or duodenum. There are many kinds of endoscopic treatments, such as argon plasma coagulation, electrocoagulation, heat probe, and submucosal injection of hypertonic saline mixed with epinephrine for gastric angiodysplasia. However, these treatment methods are associated with high rate of rebleeding. In order to avoid the recurrence, endoscopic band ligation has recently been used as an alternative method for endoscopic treatment of gastric angiodysplasia. We encountered a case of gastric angiodysplasia that presented with overt bleeding and anemia, and was successfully treated with endoscopic band ligation.

In order to investigate the effects of environmental scientific education on high school students' environmental knowledge, behavior, and practice, this study selected the test group of two schools that enforce environmental scientific education and the control group of two schools that do not enforce it. These are the results of the comparison between two groups. 1. The comparison of the average mark on the environmental knowledge, behavior, practice between two groups showed following results. In regard to the knowledge, the mark of the test group was higher than that of the control group. (p<0.001) and as for the behavior, the point of the test group was also higher than the control group(p<0.05). With respect to the practice, two groups made little difference. 2. The factor that had most greatest influence on the environmental knowledge was the students' school achievements(R2=15.0%), and in turn, the environmental instructions and the degree of consciousness on the necessity of environmental preservation were the important factors. In regard to the behavior, the degree of consciousness on the necessity of environmental preservation was the most important factor(22.1% of reliability), and in turn, the degree of concern on the environmental problems, the school achievements, and the proportions of parents' environmental preservation practice were important. The coefficient of reliability was 29.1%. As for the practice, the most far-reaching factor was the extent of the students' concern on the environmental problems(19.3% of reliability). and the proportions of parents' environmental preservation practice, the degree of the consciousness on the necessity of environmental preservation, the level of the economic conditions, the extent of parents' concern on the environmental problems were important in turn. The coefficient of reliability on the practice were 30.2%.

김현갑,배재근 서울産業大學校 1996 논문집 Vol.43 No.1

본 연구는 생물학적 탈취시스템에 있어서 경제적이며 실용적인 담체개발을 목적으로 수행되었다. 담체로서 왕겨를 사용했으며, 이 왕겨만으로는 탈취효과를 기대할 수 없으므로 왕겨에 하수슬러지를 혼합시켜 일정기간동안 퇴비화시켜 사용했다. 이러한 생물담체를 3단의 충진탑에 넣어 샘물담체중에 포함된 미생물을 이용하여 악취의 제거 가능성에 대하여 검토하였다. 황화수소에 대한 탈취정도를 농도를 변화시켜 가면서 실험한 결과, SV 30 에서 250ppm까지 제거되는 것이 관찰되었으며, 암모니아가스의 경우에는 SV 30에서 480ppm까지도 제거가 가능한 것으로 나타났다. 또한 분해단계를 검정하기 위하여 3단의 담체충진조에 대하여 가스의 농도를 측정해 본 결과, 담체를 통과하면서 농도가 점점 떨어지는 현상이 관찰되어 생물학적으로 미생물에 의하여 분해되는 것을 알 수 있었다. 지금까지 생물학적 탈취에 많은 담체를 사용했으나, 고가이면서 압력손실이 높아 경제적으로 사용하는 것이 불가능했다. 본 연구에서 검토된 왕겨를 퇴비화에 의하여 처리한 것은 구입이 용이하며, 쉽게 제작이 가능하고 경제적이라는 점에서 이용가치가 높다. This study performed to find an economical and practical media in a biological deodorization system. We used a rice husk as a media, and we added a waste sludge in the rice husk to composting for a certain period. Because we can not expect any deodorant effect with a rice husk only. We reviewed the possibility of elimination of a stench by using bacteria which exist in a biological media. We put this media in the 3-layered tower to make bacteria from the biological media. We performed experiment on deordorizablity of hydrogen sulfide by changing concentration of hydrogen sulfide. From the result, we could see that it deodorize up to 250ppm at SV 30 and it has a possibility up to 480ppm for ammonium. Also we could deodorization procedure by checking the gas concentration in 3-layered media tower. The gas concentration reduced gradually, when the gas through the media. We're due to a high expense and big pressure loss in economical aspect. The rice husk treatment by composting in this study has a high possibility of a practical use due to a low cost, an easy way of making and purchasing.

An investigation for influences of quenching temperature on ageing phenomena in Al-4%Cu and Al-4%Cu-0.06%Sn alloys has been carried out by means of the measurements of electrical resistance, hardness and tensile strength. The results obtained are summarized as follows. Hardness and electrical resistance increased remarkably with increasing of quenching temperature in both alloy at the as-quenched state. The age-hardening at the quenching temperature, 550℃ is more pronounced at the initial stage of ageing, but at the quenching temperature, 520℃ is more pronounced at the later state of ageing. The relation between the quench cluster and the initial age-hardening is indifferent if the case of step quenching which produces more the quenching cluster. The initial age-hardening is remarkably retarded in the case of up-quenching. Especially, initial age-hardening of ternary alloy is more than that of binary alloy.
