The southern strait of Jeju is a divergence point of the Tsushima Warm Current (TWC), and it is the starting point of the thermohaline circulation in the waters of the Korean Peninsula, affecting the size and frequency of marine disasters such as typhoons and tsunamis, and has a very important oceanographic impact, such as becoming a source of harmful organisms and radioactively contaminated water. Therefore, for an immediate response to these maritime disasters, real-time ocean observation is required. However, compared to other straits, in the case of southern Jeju, such wide area marine observations are insufficient. Therefore, in this study, surface current field of the southern strait of Jeju was calculated using High-Frequency radar (HF radar). the large surface current field is calculated, and post-processing and data improvement are carried out through APM (Antenna Pattern Measurement) and FOL (First Order Line), and comparative analysis is conducted using actual data. As a result, the correlation shows improvement of 0.4~0.7 and RMSE of about 1~19 cm/s. These high-frequency radar observation results will help solve domestic issues such as response to typhoons, verification of numerical models, utilization of wide area wave data, and ocean search and rescue in the future through the establishment of an open data network.

I have come to next conclusions in consequnce of documentary study about medical books of many generations regarding Jung point venesection therapy. 1. Jung point is significant as the beginning of pulse energy flow on meridian, the origin of all meridional pulse energy being located at extrimity terminal, confluence of three yin and three yang, and emergent treatment point. 2. Jung point venesection therapy was much used for the first-aid treatment for acute and thermic disease, and that is the combination of the meaning as of restoration from death and emergent treatment of Jung point and function of openning of orifice, leakage of fever, circulation of blood, remove of edema of venesection therapy. 3. It is very much used for emergency case, five sensory organ disease and CVA, heating shock and so on. Besides that digestive disease, cough, fever with cold, childhood disease, cardiac ache, thoracic disease, numbness of digitus terminal, mental disorder follow that in order. 4. Sosang, Jung point of Arm Greater Yin Lung meridian, is very much used for five sensory organ disease. Sosang is for orbital disease, sangyang for auditory disease, sosang for nasal disease, and sosnag for introitus-throat disease. 5. Ten Jung point is most used for first-aid diseases of CVA, heating shock. 6. Ten Jung point is most used for digestive disease of stomach ache, vomiting, diarrhea, intestinal convulsion. 7. Ten Jung point is most used for cold disease of cough, fever, malaria. 8. Ten Jung point, sosang, kwanchung are much used for childhood disease of acute convulsion and fever. 9. Among Jung point, sosang is most used, 34 times. Next there are Ten Jung point, kwanchung, sangyang, sotaek, jungchung, unbaek, taedon in order. In the order of frequency in use, arm channel is more used than leg channel.

In Sasang constitutional medicine, I have researched the process of visceral structure in the Eight Constitutionals under circulation of the five elements and the formation of primary source of illness. From this research, I could draw following conclusions through combination of the auxiliary psycho-formulas by applying the constitutional acupuncture therapy on the five elements diagnostic calculation. Since the arrangement for the five dimensions of organs in the eight constitutions has been formulated by circulation of the five elements in Sasang constitutions, if the five elements begin circulating count-clockwise from the reference point at the organs in Sasang constitutional medicine, the positive constitutional arrangement of organs is built up such as, the positive constitution of metal, earth, wood and water, while begin circulating clockwise, the negative constitutional arrangement of organs is formulated, such as the negative constitutions of metal, earth, wood and water. The source of illness results from imbalance of the organic force being generated by transfer of the five elements from compatibility to incompatibility when the five elements circulate. Hence, it has been acknowledged that if the source of illness comes from the strongest organ, it is the time when circulation of the five elements progresses from the second organ (the second strongest) in incompatibility, and if the source of illness comes from the weakest organ, it is the time when circulation of the five elements progresses from the third organ (the middle) in incompatibility. It is considered proper to diagnose meridians of the pericardium and the Triple Burners rather than to diagnose meridians of the heart and the small intestine which forms the visceral arrangement of the eight constitutions. For instance, the auxiliary psycho-formula obtains its prescription by attenuating the first organ (the strongest) while augmenting the fourth organ (the second weakest) when the axis of incompatibility in the five elements circulation crosses the second and the third organs, and it gets its prescription by attenuating the second organ(the second strongest) while augmenting the fifth organ(the weakest) when the axis of incompatibility in the five elements circulation crosses the third and the fourth organs. In addition, when medicating, the $4{\sim}5$ times of repeated performance can be assumed to represent the amount of an energy that each organ bears depending on the phase in the arrangement of the eight constitutional organs.

By making use of the EAV(Electroacupuncture acc. Voll) combined meridian theory of oriental medicine with electronics which was contrived to recognize the physiological and pathological changes of human body, the following conclusions were made in comparison with EAV measurements and types of symptoms(anxiety & headache, fatigue, palpitation, dizzness, abdominal distension. nausea, gastric disturbance. constipation & diarrhea, fatty liver, cva), QSCC, and blood type test. 367 patients including 124 with nervous gastrointestinal problems were selected for this research. 1. From the point of variance of the tested patients 124 nervous gastrointestinal patients, Liver meridian and Spleen meridian showed hyperenergia and Large intestine meridian, Circulation meridian, Triple warmer meridian showed hypoergia 2. In each symptom as the nervous gastrointestinal symptom Liver meridian showed hyperenergia, Large intestine meridian, Circulation meridian and Triple warmer meridian showed hypoergia . 3. In an objective comparison with other symptoms, firstly among the headache & anxiety group left Gall Bladder, Triple warmer and Stomach meridian showed remarkable hypoergia, secondly among fatigue group showed hypoergia in Triple warmer meidian and hyperenergia of Stomach meridian. and thirdly among palpitation group showed hypoergia of Kidney meridian, and lastly among dizzness group showed hypoergia of Gall Bladder, Stomach, Circulation and Small intestine meridian. 4. All of gastric disturbance, nausea, abdominal distention, constipation and diarrhea group showed hyperenergia in Stomach meridian and Spleen meridian. gastric disturbance group showed remarkably hypoergia in Circulation. Small intestine, Lung and Large intestine meridian. Nausea group showed hypoergia in Gall bladder and Urinary bladder meridian. Abdominal distenton group showed hypoergia of Large intestine. Constipation and diarrhea group showed hypoergia of Kidney and left Circulation meridian. 5. Fatty liver group showed hyperenergia of Liver meridian of 83.3%, Gall Bladder, Stomach and Spleen meridian. Urinary bladder and Kidney meridian showed hypoergia 6. CVA group showed hyperenergia in Liver and Circulation meridian. 7. Blood type in typical classification had no significant bearings on each other. 8. QSCC for the attempt of objective materials of constitutional diagnosis had no correlativity in comparison with EAV measurements. In conclusion EAV is thought be used as a diagnostic method in oriental medicine and further research is needed regarding it can be used as a useful method for verifying the characteristics and early finding of symptoms.

Recently, researchers have become interested in natural ester fluids, as they are an environmentally friendly alternative to mineral oils. Natural ester fluids are a natural resource made from plants; they have higher biodegradability, flash, and fire points, and a greater permittivity compared to conventional mineral oils. However, natural ester fluids also have a higher pour point, viscosity, and water content. These characteristics can hamper circulation and impair the electrical properties of an oil-filled transformer. A large amount of data has been accumulated over the years in regards to mineral insulating oil involving dielectric breakdown voltage and lightning impulse tests. However, natural ester fluids have not had their electrical properties sufficiently characterized. In this paper, we present an investigation into the characteristics of the electrical discharge development in natural ester fluids and in an oil-filled transformer near the pour points. The experiment results show that the electrical properties decreased according to a decrease in the ambient temperature and freezing time. It was found that the pour point and water content of natural ester fluids have a significant effect on the electrical properties.

In vacuum ejector-diffuser systems where a finite volume secondary chamber is used, the secondary jet exhibits transient characteristics during start-up. A steady state is achieved after some time in which mass entrainment prevails indefinitely inside the ejector, though there is no flow from the secondary chamber. An attempt is made in this work to study the infinite entrainment of secondary jet into the primary jet from a finite secondary chamber, with the help of a computational fluid dynamics method. The present study is also intended to identify the operating range of vacuum ejector-diffuser systems where the steady flow assumption can be applied without uncertainty. The results obtained show that the only condition in which an infinite mass entrainment is possible is the generation of a re-circulation zone near the primary nozzle exit. The flow in the secondary chamber attains a state of dynamic equilibrium at this point. Steady flow assumption is valid only after this point.

This paper investigates the transient characteristics of grounding systems used in under-ground distribution power cables. Recently, two kinds of grounding system are used for underground distribution cables in Korea. The first one is conventional multi-point grounding system, the other is newly proposed non-bundled common grounding system. The non-bundled common grounding system has an advantage the decreasing the power loss due to decrease of the shield circulation current. In this paper, the lightning overvoltage induced in neutral wire (in case of non-bundled common grounding system, overvoltage between opened neural wires and grounding in each phase) of these two kinds of grounding systems are estimated and compared by field tests and EMTP simulations. The EMTP simulation methods are firstly verified by comparison of measurement and simulation. Finally, the insulation level against lightning is expected by EMTP simulation results using verified model.

The Main objective of this study is to find consumer attitude toward the Sanitary Regulation of Foods. In view of consumerism, this result will be used in re-regulating the law. Among the Sanitary Regulation of Foods, this study focuses on the Standard of prepackaged Food Labelling, because it is related both with the advertising from the food manufacturer's point of view and with the perception about the food itself from the consumer's point of view. After reviewing the previous studies and related provisions about the Standard of Prepackaged food Labelling, and compare other sanitary regulation of foods in developed countries (U.S.A. and Japan), basic research framework was derived. The research framework focuses on the user perception about the validity of provisions about the Standard of Prepackaged Food Labelling, and on the existance of exaggeration in food advertising using prepackaged foods. Data were collected through questionaires from the sample covering 374 food customers. The data were analyzed by frequency test and the important findings of this study are as follows. Most food consumers consider such provisions as date of manufacturing, circulation time limit, cautions for food handling, price, and manufacturer as important factors in buying food products. Among these factors, the date of manufacturing and circulation time limit are most critical factors, and must be labelled correctly on the prepackaged food cover. But other provisions which do not affect on consumer's buying decision (e.g. business admission number, self standard number) need not be labelled. From this study, we can conclude that the provisions about the standard of prepackaged Food Labelling currently used must be devided into two parts. One is 'mandatory provisions' which must be obeyed by all food manufacturets, and the other is 'autonomous provisions' which need not be obeyed by all food manufacturers. And mandatory provisions need to be regylated more strongly than now.
