崔亢奎,金泰起 관동대학교 1972 關大論文集 Vol.1 No.1

Lately it has been deeply marked that the Hydro Speed Governer turns up an important and outstanding appearence as an automatic controlling system in the field of marine diesel engine. In the past it was mainly adopted the mechanical governer for that function, but it has brought remarkable improvement to the technique of analysis due to the application with modern electronic computer today. It looks very hard project to analyze the Hydro Speed Governing System of engine, however, it is possible to seek for the method of measuring the approximate Value of Transient Response if certain appropriate assumption and hypotheses set up. In this thesis, the device of Hydro-Speed Governing for marine diesel engine is aimly studied. Particularly on the fishering marine diesel engine installed with the C.P.P.- Controlable pitch propeller-, the relationship of Reference Input and Controlled Value, the Steady State operation and the Transient Response on the relationship of the Disturbance and Control System are apparently investigated over and analyzed of the general coefficients by the theoretical computation and experimental method. As the program for the remote control and automation of ship got into request of rapid development, but it requires more improvement on it until approaching to standard available. Hydro Speed Governer posses a sufficient power with out-put and wide range of response, isochronous character, therefore, this is precisely capable on a definite speed running no matter of disturbance. In this treatise, the speed governer manufactured by American Woodward Co.was adopted for the material, with which the ships hull, engine and speed governer were analyszed in trinity. In the first chapter, there investigated over the Steady State Operation and Transient Response on the hull and engine. The second chapter contains over the investigation of Stability through general system by Disturbance with the Speed Governer installed on board.

孫興大 건국대학교 1986 論文集 Vol.22 No.1

This experiments were carried out to study changes of haemolymph proteins during development of silkworm, Bombyx mori by SDS-polyacrylamide gel electrophoresis. The results obtained were follows; 1. Bands of haemolymph proteins seperated during the metamorphosis of silkworm showed 20 bands and those molecular weights ranged from 12,800 to 106,000 daltons. 2. Major bands (7 and 15) were changed quantitatively, band 7 showed predominant levels from the middle 5th instar to the middle pupa stage, band 15 was leached the maximum levels at spining and then significantly decreased on prepupa stage, those molecular weights were determined to be 27,000 and 79,000 daltons respectively. 3. Female specific proteins of band 17 and 18 (mol. wt. 102,000 and 102,500 daltons) showed from the 1st day after pupation. 4. Concentration of low molecular weight proteins (mol. wt. 16,300∼18,500 daltons) at adult stage were increased. 5. In conclusion, it was suggested that the major haemolymph proteins in silkworm should be utilized to form tissues of pupa and adult, female specific proteins involved in the egg formation.

Background : Patients with chronic renal fialure have a substantially elevated risk of death from cardiovascular diseases than do the general population. the patients with chronic renal failure are at significantly increased freqeuncy of hypertension, hyperlipidemia, and diabetes mellitus which are known to the risk factors of the coronary artery diseases, and the prevalence of the coronary artery diseases in chronic renal failure patients is highly associated with the hemodynamic disorder and metabolic abnormalities. therefore we expected that the coronary angiographic findings in patients with chronic renal failure should be different from the general population (control groups) and investigated the risk factors contributing to coronary artery diseases. Method : we have retrospectively compared the coronary angiographic findings of 44 patients with chronic renal failure on hemodialysis with that of 88 patients in the general population and investigated the factors contributing to the development and acceleration of coronary artery diseases in patients with chronic renal failure Result : Hypertension and diabetes mellitus which is risk factors for coronary artery disease is significantly increased in patients with chronic renal failure, in coronary angiographic finding the severity of the lesion is worse. the incidence of PCI or CABG of patients with chronic renal failure is more than that of control group but statistically no difference between patients with chronic renal failure and control group. the sex, the duration of disease, the duration of dialysis, serum creatinine in patients with chronic renal failure have no correlation to the prevalence of coronary artery disease and severity of lesion. hyperglycemic patients with chronic renal failure have high incidence of coronary artery disease and are worse in the severity of lesion Conclusions : There is significantly increased the pevalence and severity of involving multiple coronary artery diseses in hyperglycemic patients with CRF.

Late Bronze and Iron Age Female Figurines Found in Palestine

강대흥 聖潔大學校 聖潔神學硏究所 1997 聖潔神學硏究 Vol.2 No.-

AbstractFemale terracotta figurines have been found most LBA and the Iron Age sites ever excavated. The exact identity of the figurines seems to be unestablished, but it has been suggested that they may have represented the Canaanite goddesses of fertility, Asherah, Anat or Astarte, and that the Iron Age villagers of the highlands probably worshipped a combination of all three, gathered under the generic name Asherah. The Hebrew Bible and epigraphical evidence such as Kuntillet Ajrud and Khirbet el-Qom inscriptions, and archaeological evidence testify that Asherah as the goddess or the asherah as cultic symbol was acceptable in early Israelite society in its cultic activities. This evidence also indicates the cultic artifactual continuity between LBA and the Iron Age.

The purpose of this study was to identify the effect of endurance exercise program on the middle-aged women. Six subjects were recruited from among volunteers responding to advertisements placed around the university community. All subjects, with no experience in regular physical activity participated in an interventional training consisting of swimming and stretching three days a week for 10weeks. Pre-and post blood lipid levels, such as Total Cholesterol(TC), High Density Lipoprotein Cholesterol(HDL-C), Low Density Lipoprotein Cholesterol(LDL-C), and Triglyceride(TG) were measured. A paired t-test showed results that were significant the .05 level were HDL-C , LDL-C, TG, and TC/HDL-C Ratio. The main finding of the study was that the role of endurance training, as prescribed in our study has the effect of making improvements in blood lipid levels for the middle-aged women. 1. After a 10week period of endurance exercise, the Total Cholesterol(TC) level was higher than that of pre-test. But the difference no showed the statistical significance. 2. After a 10week period of endurance exercise, the High Density Lipoprotein Cholesterol(HDL-C) Low Density Lipoprotein Cholesterol(LDL-C). Triglyceride(TG) level was higher than that of pre-test. and the difference showed the Statistical significance. In conclusion, even though there was significant in blood lipid levels after endurance exercise, swimming has a beneficial on improving in the middle-aged women.
