멀티캐스트 ATM망에서 대체가상경로의 설정을 위한 유전 알고리듬

김여근,송원섭,곽재승 한국경영과학회 2000 韓國經營科學會誌 Vol.25 No.2

Multicasting is the simultaneous transmission of data to multiple destinations. In multicast ATM networks, the effect of failures on transmission links or nodes can be catastrophic, so that the issue of survivability is of great importance. However, little attention has been paid to the problem of multicast restoration. This paper presents an efficient heuristic technique for routing backup virtual paths in multicast networks with link failure. Genetic algorithm is employed here as a heuristic. In the application of genetic algorithm to the problem, a new genetic encoding and decoding method, and genetic operators are proposed in this paper. The other several heuristics are also presented in order to assess the performance of the proposed algorithm. Experimental results demonstrate that our algorithm is a promising approach to solving the problem.

Background: The diabetic patients are at significantly increased risk of developing vascular disease. It's etiology may involve oxidative damage by free radiacals and protection againse such damage can be offered by antioxidants. We investigated that oxidative stress as assessed by measurement of total antioxidant status may play a role in development of diabetes mellitus. Method: We measured total antioxiant status using merchandised kit, glycated hemeglobin(HbA1c) in 46 type 2 diabetes mellitus patients and 50 healthy matched control subjects. Result: The total antioxidant status(TAS) was 2.10(±0.04) mmol/L in uncontrolled type 2 DM patients, 2.60(±0.03) in controlled type 2 DM patients and 2.70(±0.16) in healthy control subjects. TAS was significantly lower(P<0.05) in uncontrolled type 2 DM patients, but no significant association between in controlled type 2 DM patients and healthy control subjects. The TAS was 2.00(±0.17) mmol/L in complicated type 2 DM patients and 2.10(±0.29) uncomplicated type 2 DM patients. There was no significant associations between complicated type 2 DM patients and uncomplicated type 2 DM patients. Conclusion: Poor glycemic control is associated with reduced TAS in type 2 DM patients. TAS was thought indirect index that predict glycemic control of type 2 DM patients.

全南地方의 産前俗

尹汝松 호남대학교 1986 호남대학교 학술논문집 Vol.7 No.2

This paper analyzes the fo lkcustoms before childbirth among the rural people in Cheonnam area. The folkcustoms in this area are carefully analyzed with special reference to the prayer custom for a child(especi- ally for a son), the taboo during the period of pregnancy, the foreknow- ledge of the sex of a fetus, the preventive measures for miscarriage, the measures for easy labor, and so on. The analysis of the materials of above folkcustoms has reavealed the following summar ized. 1)The prater for a child is a custom of praying to divine spirits for a child or of playing some magic. When people devote themselves to spirits for pregnancy, they go to a specific tree, a mountain, or a spring, and so forth. They sometimes eat such fruits as red peppers, must, or jujubes. Women who pray for pregnancy quite interestingly make it a to rule to take three pieces of the above-mentioned seeds. 2) The dream of forthcoming conception is thought of as a dream to foretell pregnancy. This dream in most casec is dreamed by women. Hearing of the dream, people predict the sex or the fate of the unborn baby. In the dreams of forthcoming conception there appear such familiar things around us as animals or prants, or celestial bodies. The qualities or characteristics of the things come up in dream are the clues to foretell the sex of the unborn child. lf the objects in dream are big, cruel, or red. people foretell a son while they expect the birth of a daughter if the things in dream are little, pretty, or blue. 3) The taboo in pregnancy is a custom in which the pregnant woman and or her family do not take some specific foods or abstain from unclean doings in order to attain the mother’s sound health and the unborn baby’s good growth after birth. For example, woman in pregnancy does not care for eating octopus for fear that she deliver a deformed baby without bones. And people suppose that chimney repair might cause for a childbirth of a split. These preventive measures of various types are based upon thr law of similarity that some actions might be the causes for the results of similar aspects. And in some cases the women in pregnancy keep taboos not only for themselves but also for other women. 4) The familt with a pregnant woman desires to know to sex or the unbo- rn baby. To meet this desire some ways to forell the sex of the fetus are devised. There are tow kinds of prediction; one is to predict the sex by noting the mother’s physical transformation or the fetus’movements, and the other is to infer the sex of the baby from her very former childbirth. most of these was come from a great number of experiences so that they are thought to be of great possibility. 5) The preventive measures for miscarriage can be said to be a kind of folk remedy to prevent the abortive birth and to maintain a mormal growth of the fetus. Many pregent women are in the habit of drinking the water of boiled persimmon calyxes, door handles, or axes. These things are in common to have the quality of great abhesive power. The measures for the women in pregnancy to prevent the abortion or hard labor and to guaranted an easy delivery are the measures for easy labor. In these measures are included the girdling the prognant woman with her husband’s waist belt. the clothing the mother with the costume borrowed from a women who delivers easily, and the drinking the water of boiled belt of her husband. In most casesthesemeasures are greatly dependant upon her husband, other womon of easy labor, sorceresses, or magic things rather than the pregnant women herself.

The magnetic polishing is the useful method to finish some machinery fabrications by using magnetic power. This method is one of the precision techniques and has an aim for clean technology in the transportation of the pure gas in the clean pipes. The magnetic abrasive polishing method is not so common in the field of machine that it is not known to widely. There are rarely researcher in this field because of non-effectiveness of magnetic abrasive. Therefore, in this paper we deals with the development of the magnetic abrasive with the use of Ba-Ferrite. In this development, abrasive grain WA has been made by using the resin bond fabricated at low temperature. And magnetic abrasive powder was fabricated from the Ba-Ferrite which was crushed into 200 mesh. The XRD analysis result shows that only WA abrasive and Ba-Ferrite crystal peaks were detected, explaining that resin bond was not any more to contribute chemical reaction. From SEM analysis, we found that WA abrasive and Ba-Ferrite were strongly bonding with each other.

Background: There is no effective treatment modality for caustic agent ingestion. Dilution and neutralization are prohibited because of the risk of secondary thermal injury. This experiment is designed to evaluate the amount of dilution and neutralization heat and to gauge the applicability of dilution and neutralization therapy using cold solutions to suppress the peak temperature. Methods: This is an in-vitro chemical experiment. HCl, CH3COOH, NaOH, and NH4OH are selected as representatives of strong and weak acids and strong and weak alkali, respectively. 20℃, 11.6M, 5.8M, and 2.9M solutions of each acid and alkali are made and mixed using a magnetic stirrer at a room air temperature of 28℃. The peak temperature, the duration above 40℃, and the heat amount are measured or calculated. Results: When a 11.6M HCl or NaOH solution is diluted with same amount of water, 32 or 18cal. per mL of HCl or NaOH is produced, respectively. HCl produces a significant peak temperature, but NaOH does not. The lower the concentration, the lower the amount of heat production. 11.6M CH3COOH and NH4OH solutions don't produce dilution heat.11.6M and 5.8M solutions of all acids and alkali produce destructive neutralization heat. However, 2.9M solutions produce neutralization heat which might be controllable. When a 11.6M HCl or NaOH solution is neutralized with a -10℃ 2.9 M NaOH or HCl solution, respectively, the peak temperature produced is below 40℃ and seems to add little thermal damage to viable tissue. Conclusion: Dilution and neutralization with a cold solution in cases of strong acid or alkali ingestion is a promising method to avoid thermal injury.
