This research was carried out to examine the correlation between the patients of functional dyspepsia and four constitution (Sasang Constitution). This research examined the correlation of functional dyspepsia versus Sasang Constitution, chronic fatigue, and mental stress in 100 cases of functional dyspepsia. No significant correlation was witnessed between average duration of dyspepsia and gender, and smorking. There was tendency of increased duration of indigestion in relation with length of chronic fatigue and the degree of mental stress. Significant difference was found between the patients with indigestion and Sasang Constitution types. Soeumin among the patients with indigestion were numerous and it was significantly different with normal people. Significant correlation was found between the period of indigestion and chronic fatigue and the degree of mental stress. Significant difference was found between the patients with indigestion and Sasang Constitution types.

This study was carried out an experimental and finite element analysis on the fracture behavior of straight pipes with local wall thinning under internal pressure. Local wall thinning was machined on the pipes in order to simulate erosion/corrosion metal loss. The configurations of the eroded area has an eroded ratio of d/t=0.80~0.92 and an eroded length of l=25, 50 and 102 mm. Three-dimensional elastic-plastic analyses were also carried out using the finite element method, which is able to accurately simulate failure behaviors. In regards to the relation ship between pressure and eroded ratio, the criterion that can be used safely under operating pressure and design pressure were obtained from this calculation. The results of this calculation were in relatively good agreement with that of the experiment.

The investigations included the measurements of volume currents and also internal space charges on epoxy samples of mm thicknesses. The current versus time relations were shown to correspond well with classical forms of dielectric response such as the Curie-von Schweidler model. After the time transient, near steady currents were extremely small and exhibited a significant temperature dependence, similar in relation to the Poole-Frenkel hoping transport model. Equivalent resistances were on the order of 1019 ohms and represent very weak charge transport. Electrically stimulated acoustic waves were used to quantify the small internal charges that would accumulate within the epoxy. There was a notable homocharge near both anode and cathode. The dielectric response and the internal charge were related to show a consistent model for charge transport within unfilled epoxy.

The purpose of this study is to estimate the availability of acoustic emission method to the internal leak of the valves at nuclear power plants. The acoustic emission method was applied to the valves at the site, and the background noise was measured for the abnormal plant condition. From the comparison of the background noise data with the experimental results as to relation between leak flow and acoustic signal, the minimum leak flow rates that can be detected by acoustic signal was suggested. When the background levels are higher than the acoustic signal, the method described below was considered that the analysis the remainder among the background noise frequency spectrum and the acoustic signal spectrum become a very useful leak detection method. A few experimental examples of the spectrum analysis that varied the background noise characteristic were given.

Fe-Ni alloy nanoparticles were prepared by ERC (Evaporation and Rapid Condensation) method, and the crystal structure and the behavior of martensite for the nanosized alloy particles were investigated by X-ray diffraction analysis. The relation between the rate of martensite transformation and the internal strain of austenite was discussed. The lattice spaces of austenite and martensite for the nanoparticles agreed with those of the bulk materials. The rate of martensite transformation from austenite and the internal strain of austenite was reduced with decreasing the average size of Fe-Ni nanoparticles. It was thought that the residual austenite in the Ni content range of 11∼l5at% was caused by the internal strain, and the residual martensite in the Ni content range of 32∼36at% had its origin in the high surface energy of nanoparticles.

Insulators for high-voltage and large-power should be endured mechanically the weight of mold bushing itself and the force of pushed from contact with circuit breaker and conductor. But dielectric breakdown could be occurred result from the external circumstances and internal factors such as chemical reaction, partial discharge, change of temperature and the relation of temperature-time in process of casting. Therefore, to get rid of external and internal factors of dielectric breakdown. Furthermore, to prevent the internal cracks, void, cavity which resulted from the contraction originated on the interface between copper and epoxy resin, formed semi-conductive layer with partially carbon painted on copper bar. The PD properties and the insulation qualities of epoxy molded insulators were improved by roles of cushions for the direction of diameter and natural sliding effects as like separated from conductor for the direction of length.

Emerging attacks aim to access proprietary assets and steal data for business or political motives, such as Operation Aurora and Operation Shady RAT. Skilled Intruders would likely remove their traces on targeted hosts, but their network movements, which are continuously recorded by network devices, cannot be easily eliminated by themselves. However, without complete knowledge about both inbound/outbound and internal traffic, it is difficult for security team to unveil hidden traces of intruders. In this paper, we propose an autonomous anomaly detection system based on behavior profiling and relation mining. The single-hop access profiling model employ a novel linear grouping algorithm PSOLGA to create behavior profiles for each individual server application discovered automatically in historical flow analysis. Besides that, the double-hop access relation model utilizes in-memory graph to mine time-sequenced access relations between different server applications. Using the behavior profiles and relation rules, this approach is able to detect possible anomalies and violations in real-time detection. Finally, the experimental results demonstrate that the designed models are promising in terms of accuracy and computational efficiency.

It has been reported that the cancer patient's quality of life is influenced by the perceived health state, self-esteem, health locus of control, social support, whether there is a pain or not, the stage of a disease, the period of a disease, etc, and however, there has been scarcely the research into the fact at home whose cultural and social backgrounds are entire1y different from those of American and European Countries. Accordingly, the author of this thesis performed this study. considering that it is necessary to know the relations between the health locus of control which make it possible to predict the object's behavior related to health and to make plans to induce the object or patient into sound behavior and the quality of life which is closely related to the cancer patient's health, emotion, society, economy, etc. on the whole. This study, a cross-sectional one, includes 135 subjects of $in{\cdot}out$ patients registered at Y University Hospital whose age are more than 20 years, From these patients, data were collected for two weeks through the questionnaire which content concerns about the quality of life and the health locus of control. All the collected data were processed and analyzed through Student's t-test, ANOVA, and the calculation of Pearson Correlation Coefficient, using the SAS program 1. It appeared that the disposition of health locus of control was mostly inclined to the disposition of powerful other health locus of control($28.37{\pm}4.24$), then inclined to internal health locus of control($27.03{\pm}4.17$), and next to chance health locus of control($19.71{\pm}4.97$) By the way. the disposition of powerful other health locus of control appeared a tittle bit higher than internal health locus of control 2. The degree of the quality of life appeared to be 137.54 points in the average of total points and 3.11 in the average evaluation mark. It appeared that the quality of life was most significantly influenced by a factor of 'relations with neighbors' and least significantly influenced by factors of physical conditions and functions. 3. It appeared that the relation between the disposition of health locus of control and the quality of life has nothing to do with the relation between internal health locus of control and the quality of life(r=.1446, P>.05) and also with the relation between the disposition of powerful other health locus of control(r=.0385, P>.05). In conclusion, in the study it has been found out that there is no correlation between the health locus of control and the quality of life, and however it is sound to induce the cancer patient to internal health locus of control. Therefore, it is necessary that under the special circumstances, the cancer patient's behavior should be predicted, thereby inducing the patient to the sound change of his or her behavior. Also in order that the patient enjoys his or her life satisfactorily while living, It is deemed that some kind of multilateral meditation in health and treatment is necessary so that the patient can feel the relief of pain, better health, etc.

Angioedema is a localized transient swelling of sudden onset that can occur in the face, lips, tongue, hand, feet, respiratory system and gastrointestinal system. Angioedema is classified as allergy, hereditary, idiopathic or induced by medication as like aspirin, nonsteroidal anti-inflammatory agents, opiates, antibiotics, and angiotensin-converting enzyme. Angiotensin-converting enzyme inhibitors are widely prescribed for hypertension and heart failure. This drug is commonly associated with angioedema which may be potentially life threatening. We experienced a case of angioedema induced by ACE inhibitor (angiotensin-converting enzyme inhibitor) in a 74-year-old patient who took ACE inhibitor to control hypertension during hospitalization. We thought the angioedema in the face had relation to myenzhong (面腫, mienjong) in oriental medicine. Weiling-tang (Wiryung-tang) was effective for angioedema in the face. As a result the symptoms disappeared rapidly. After 6 days, the patient's symptoms had notably improved.

Yuk Gi (六氣) in oriental medicine have influence on the body and, the body which adapt itself to the change of Yuk Gi, can maintain the activity of life, so five vital organs of the body have relation to Yuk Gi. The relation between Lung and Jo (燥) is well described from Whang Jae Nai Kyung (黃帝內經), the oldest book in oriental medicine, to the old books of Chung (淸) dynasty and modern documents. By the way, when autumn has come and the environment become dry, clear and mild ability of lung is losed. It's because dryness evil (燥邪) occured the trouble of Lung. The following results were obtained according to these facts which is considreed peviodically and bibliographically. 1. According to flourishing the functional activities of dryness (燥氣), as reducing the functional activities of water (水氣) of upper portion of the body cavity (上焦), Kidny Water (腎水) is not nutrited and Fire-Heat (火熱) is activiting, which is evoking the disease of Lung. 2. In the disease of Lung, there are many diseases because of dryness evil (燥邪), thinking that, which methods of treatment are the principal one of 'Clear up the lung and moisten dryness (淸肺潤煥)'. I found that Lung and Jo (燥) have the relation of intimacy. 3. Creating the vital essence of the kidney (腎水) to the functional activities of the lung (肺氣) is in prosperous condition, the functional activities of fire (火氣) stabilize the function of Lung become normal condition which wear said in the literary.
