朴彦坤,洪錫珠 홍익대학교 1996 弘大論叢 Vol.28 No.-

This study investigates the practical aspects of Dongs?sataek Lone(東 ·西四宅論), korean traditional housing. Dongsasataek Lone is a theory that lay of house and gate tells fortunes, and it is composed of Dongsataek(north, east, southeast, south) and Sasataek(northeast, northwest, west, southwest). Dongs?sataek Lone contains as follows : (1) A house in Dongsataek(north, east, southeast, south) have to gate Dongsataek. And in the case of a house in Sasataek(northeast, northwest, west, southwest) have to gate S?sataek. (2) Anchae(a place for women) have not to be seen through clearly and trespassed for privacy. (3) A gate in northwest is not so good for seasonal wind of winter. (4) A house facing south is the best disposition, and then a house facing southeast, southwest, or east is good anyway. But a house facing north, northeast, northwest, or west is not so good. And, in this research, a compass put the center of a court. Accordingly, Dongs?sataek Lone can be applied practically to a contemporary house planning.

For the purpose of this study is to analyze the flora of plants and forest vegetation of Mt. Keumjung. The results of the study can be described as below. 1. Plants growing at the 8 quadrates of the Mt. Keumjung were 24 families, 36 genuses and 3 species in 1994 and 23 families, 33 genuses and 49 species in 2001. 2. The soil acidity of the 8 areas surveyed here in 2001 was 4.8 to 5.5 in pH, indicating that the soil was gradually being oxidized. The soil hardness was found 15.8 to 28.3 mm, 20.8 in average. 3. Pinus rigida was found highest In dominance, occupying 352% of the total population of arbors, followed by 2.96% for Alnus hirsuta and 2.51 for Styrax japonicn while among the azalea was found highest in dominance, accounting for 44.49% out of the total population of shrubs, followed by 15.14% for Rhododendron yedoense var. poukanese and 3.92 for Rubus idaeus var. concolor. 4. Of the 8 quadrates, sect 8 of the North Gate was highest in the number of extinct trees. 15 kinds. This is probably because of the pressure by climbers' steps. Sect 3 of the West Gate and sect 5 of the South gate had 8 kinds of extinct trees, respectively. The number of newly appeared trees was highest at sect 7 of the North Gate, 8 kinds, followed by sect 5 and sect 6, respectively 5 kinds. 5. At the area of the West Gate(sect 3, sect 4) to which the sabbatical year system(Area : Puk-gu district and a part of Keumjung-gu district) was applied, 21 plant species newly appeared, more than any of the other areas. At the area of the South Gate(sect 5, sect 6). in contrast, 15 plant species disappeared and at the area of the North Gate(sect 7, sect 8). as many as 20 became extinct. The areas surveyed here showed that the extinction of plant species was mainly due to the pressure by climbers' steps rather than to changes in natural environment. To protect the forest and plants of the Mt. Keumjung, thus, it is necessary to increase the period and area of the sabbatical year system and take more effective actions for the management of the forest and plants.

손대곤,장석준,송근정,이한식 大韓應急醫學會 1997 대한응급의학회지 Vol.8 No.1

To raise the quality of research, medical articles which are feasible and objective must be continuously published and be continuously monitored. All articles published in the Journal of the Korean Society of Emergency from November, 1990 to November, 1995 were compared with a foreign emergency medical journal, the American Journal of Emergency Medicine(AJE). Classifying the articles in the Journal of the Korean Society of Emergency Medicine, there were 15 (8.4%) review articles, 145 (81.0%) original articles and 19 (10.6%) case reports. In the AJE, there were 103 (15.1%) review articles, 304 (44.4%) original articles and 277 (40.5%) case reports. Classifying the original articles in the Journal of the Korean Society of Emergency Medicine, There were 13 (9.0%) experimental articles, 88 (60.7%) descriptive articles and 44 (30.3%) analytic articles. In the AJE, there were 40 (13.2%) experimental articles, 59 (19.4%) descriptive articles and 205 (67.4%) analytic articles. The classification of original articles according to frequency in the Journal of the Korean Society of Emergency Medicine is trauma, resuscitation, toxicology and medical emergency, where as the AJE is medical emergency, trauma, toxicology and EMS. For statistical methods used in original articles, 90 (62.1%) case did not do any statistical analysis or where only descriptive statistics were used. In 6 (4.1%) cases the statistical level was described but statistical methods were nonmentioned. By simple calssificaton study, there were 44 (30.3%) cases of original articles in the Journal of the Korean Society of Emergency Medicine, and 6 (2.0%) cases in the AJE. Because the development of Emergency Medicine as a special department is based on logical articles, organization of articles have study design, make hypothesis, sample gathering, statistical analysis and feasibility of conclusion. For this, the emergency training course needs a course on research methodology.

In thia paper , we have approached to the recognition system from assuming that two systems, time-frequency and nonlinear-dynamic pattem have different recognition range respectively. We showed that the performance of the Model connected MLP and HCNN is better than that of HMM itself. We examined HMM and HCNN under the similar conditions. The results turn out that MLP and HMM itself only show us a little change. So, we can conclude that the sysytem connected MLP and HCNN is more suit-able for speaker independent speech recognition tasks.

급성 acetaminophen 중독의 임상적 고찰

손대곤,최성욱,장석준 대한응급의학회 1996 대한응급의학회지 Vol.7 No.2

Acetaminophen-a common analgesics easily available without doctors prescription in our country-overdosed patient is one of most commonly encountered in the ED. But, acetaminophen is relatively safe drug and treatment of acetaminophen overdosage has been well established. But for the proper management of these patients, two following restrictions should be overcome. The first, serum acetaminophen level should be available immediately for proper disposition of the patients. The second one is the use of the antidote (NAC:N-acetyl cysteine, Mucomyst??) to the potentially toxic patients without delay and adequate dosage and route of administration of the NAC should be familiar to the emergency physician. Except a few hospital, serum acetaminophen level is not available in our country. This pitfall can make emergency physician delay the use of the NAC or misuse of the NAC. To overcome of this pitfall, we reviewed patients who admitted in our hospital due to acetaminophen overdosage from July 1. 1993 to June 30. 1995. Total 18 patients enrelled in our study, 4 male, mean age 25.5 years old, and mean ED presentation time after ingestion was 6.25 hours. Acetaminophen single ingestion was 14 cases and mixed ingestion was 4 cases. With the exception of the one case who ingested 3g of acetaminophen, all patients received 72 hour oral NAC as an antidote for poisoning of acetaminophen. Both NAC and MDAC(multiple dose activated charcoal) was used in 8 cases. 「Serum acetaminophen level was obtained in 12 cases」. "Three patients had showed hepatotoxicity-liver enzyme(SGOT/SGPT) level above 200 IU-recovered during hospitalization.` No fatal hepatotoxicity was noted in our study. Fourteen adjustment disorder, one personality disorder and three major depression was their final psychiatric diagnosis. Their mean hospital day was 7.2 days. In the conclusion, as the efficacy of NAC as an antidote decreases after 8 hours, treatment must be started immediately following all potentially toxic dose of acetaminophen. Administration can be stopped if the acetaminophen concentration is below the treatment line but it is important to avoid potentially fatal delay.

The causes of death of pelvic bone fracture are hemorrhage, associated internal organ injuries, sepsis, and multi-organ failure, among which hemorrhage still remains as the leading cause of death. While previous classification for pelvic bone fracture was focused on orthopedic treatment, Pennel & Sutherland suggested a new classification according to the pelvis AP film took in the emergency room. Since this classification supposedly evaluates hemorrhage from pelvic bone fracture, we are reporting on the efficiency of this classification. Out of all the 150 patients admitted to Yong Dong Severance Hospital Emergency Room from 1992, Jan. through 1994, Dec. due to pelvic bone fracture, 18 people with incomplete medical record and X-ray film excluded from the study. The study was done Cohort method and t-test was used. According to the new classification, the unstable fracture had a much more bleeding amount regardless of the type, and type I stable fracture bled more than all the other stable fracture. These were statistically meaningful. Also, there was no differences in the type of fracture when ISS(Injury Severity Scale), GCS(Glasgow Coma Scale), and associated injury were compared. In conclusion, previous classification was done according to orthopedic treatment and this classification could be done only after pelvis X-ray series and pelvic bone CT was performed. Therefore much more time is consumed, more stress is put upon the patient and no comparisons can be made in performing emergency care. On the other hand, modified Pennel &-Sutherl`s classification can be simply classified in the emergency room by taking pelvis AP film only and the bleeding amount can be measured according to the type. Therefore, this classification can be helpful in performing emergency care.

발전설비를 구성하는 주요 기기중 펌프, 발브, 배관 등의 용접부에 발생할 수 있는 균열 등의 결함을 검출하기 위한 plus-point 와전류검사탐촉자를 설계하여 결함을 검출하고 그 크기를 측정할 할 수 있는 검사기법을 연구하였다. 차동형 모드로 운전되는 plus-point 와전류탐촉자는 2개의 "I"자형 코일 이 십자형태로 교차되어 있으며, 탐촉자와 시험체 표면사이의 lift-off변화에 의한 영향이 재래식 표면 탐촉자에 비해서 작게 발생하는 특징이 있다. 결함에 대한 탐촉자 반응을 평가하기 위해서 304 스텐 인레스강 용접부에 인공결함인 균열성 노치를 방전가공하여 시험편을 제작하였으며, 이를 활용하여 plus-point 와전류탐촉자의 결함 검출, 종류 판별 및 크기를 측정할 수 있는 기법을 연구하였다. A plus-point eddy current test(ECT) probe was developed to examine the defects on the welds of pumps, valves, and pipings which are the major components of the electric power plants. non-destructive evaluation(NDE) techniques for detecting and sizing the flaws were studied adapting this probe. Differential plus-point ECT probe is consists of two "I"-type coils crossed each other and has an advantage having a small influence on the sensitivity by lift-off variation to the conventional types of probe. The specimens with crack-like electro dischrge machining(EDM) notches on the weld of type 304 stainless-steel were fabricated in order to evaluate the plus-point ECT probe response to the flaws. NDE techniques to detect and size the flaws and estimate the flaw type were established with this specimens.

This investigation is about the characteristics of phytoplankton community and physciochemical water quality of specific 6-point the Woon-kog stream system in upsteam of the Andong Lake. DO value was showed over 8.1㎎/L at each site and COD_Mn, BOD, T-N, T-P tend to increase as they stream down and that the existence and dominance of phytoplankton was low and it was difficult to conclude the definite correlation of water quality and phytoplankton community. Finally, it seemed to be desirable that alternatives for pollutional reduction should be made and performed on the basis of the continuous monitoring of the inflow to preserve the Andong Lake.
