This study investigates Japanese-made Chinese Characters in JIS X 0212-1990(Code of the Su n.0, pplementary Japanese Graphic Character Set for Information Interchange). As a results of detailed investigation, it is found that the number of Japanese-made Chinese Characters in su n.0, pplementary set reaches to 69 characters. Among them, 29 characters are not listed even in the best known chinese character dictionary [대한화사전]. 30 characters are found in the chinese character dictionaries published in Korea, while 39 characters are not found in any of those dictionaries. The distinctive characteristic of Japanese-made Chinese characters is that those chinese characters are made in order to name the things, such as fishes, birds, trees, which do not have Chinese-made Chinese Characters.

On the viewpoint of Nae-Kyung and Ju-Yeok, the Seok-Kok's Pu-Yang-Non and other oriental medical doctor's Po-Eum-Eok-Yang, Pu-Yang-Eok-Eum theory which are on the basis of the Kun-Shin-Sang-Wha theory of Nae-Kyung and Myung-Mun theory of Nan-Kyung were compared and studied. The results were as follows : 1. Ju-Yeok and Nae-Kyung said the South is Fire. And explained it as the chief object of life activity by likening to king or saint. And said the North is Water. but didn't mentioned that there exists Fire. The activity of Kun-Wha is regarded as the the chief object of life activity and the Shin-Su can be vatalized by receiving the Shim-Kun-Wha. Therefore, the Seok-Kok's opinion that Shang-Wha is the Fire received by Shin-Su matchs the theory of Nae-Kyung and Nan-Kyung. 2. The Kidney(Shin) in Nae-Kyung means Puk-Bang- Han-Su(The North Cold Water) which has two characters, charging and discharging, ascending and descending. The paragrap "Kam-Ga-Seub(坎加習)" in Ju-Yeok means Puk-Bang-Su(The North Water) which also has two characters, charging and discharging, ascending and descending. The beginning and the end. And One Eum and Two Yang of Ri Sign of divination(離卦) cannot be divided into Su-Jang and Wha-Jang, the same as that, One Yang and Two Eum of Kam Sign of divination(坎卦) is Puk-Bang-Han-Su which cannot be divided into Shin and Myung-Mun. The theory of Choa-Shin-Woo-Myung-Mun of Nan-Kyung is the result that the Shin which has two characters is regarded as two organs. Therefore, from the viewpoint of Nae-Kyung and Ju-Yeok, the Seok-Kok's opinion that the Shin is the Puk-Bang-Han-Su which charges from the right and discharges to the left is more proper. 3. For the first time, the right kidney(Woo-Shin) defined as Myung-Mun in the Nan-Kyung and it is trailblazing theory which dosen't exist in the Nae-Kyung. But from the viewpoint of Nae-Kyung, Myung-Mun-Shang-Wha which some oriental medical doctors thought importantly is considered as Shim-Po which is in charge of the order of Shim(心命). 4. The rush of heat to the upper part(上熱) is raised by blind acting of Shang-Wha which exists in the lower part. This theory is on the basis of the Myung-Mun-Shang-Wha theory of Nan-Kyung. The theory that Wha is in the Shin(Kidney) doesn't exist and only the theory exists that the fever happens by the Kun-Wha not going down but ascending in the Nae-Kyung. Therefore the Shang-Wha blind acting theory of the lower part is not coincided with the theory of Nae-Kyung. 5. When the Vital power(陽氣) is blocked by bad tendencies(邪氣) like uncontrolled joy and anger or too much cold and heat etc, the trapped heat(鬱熱) or Ascending Shang-Wha apper, so Vital power itself cannot have blind activity or excess. Therefore, the theory of oriental medical doctors that the remaining vital power is the fire(氣有餘便是火) cannot be materialized. 6. On the basis of the Woo-Shin-Myung-Mun theroy, oriental medical doctors attached importance to Shin-Eum and Shin-Yang. So they emphasized on Ja-Eum-Gang-Wha or On-Bo-Shin-Yang for curing the Fire. Contrarily, On the viewpoint of siding with the vital power which is the Good and repressing the bad tendency which is the Bad, and another viewpoint that when the vital power which is Shim-Kun-Wha moves through the body consistently and fills up the body, then the enery and blood can be made, the Seok-Kok's theory is coincided with the theory of Nae-Kyung.

As the penetration of different types of renewable energy sources (RES) and energy storage systems (ESS) increases, the importance of stability in AC microgrid is being emphasized. Especially, RES and ESS which are operated using power electronics have difference in output characteristics according to control structures. When faults like single-line-to-ground fault or islanding operation occur, this means that a fault should be interpreted in different way. Therefore, it is necessary to analyze fault characteristics in AC microgrid in case of grid-connected mode and standalone mode. In this paper, the fault analysis for AC microgrid is carried out using PSCAD/EMTDC and an overvoltage problem and the countermeasures were proposed.

The distributions of blood pressure, blood flow, and blow volume in the left common artery (LCCA) were determined using the lumping parameter method. In order to develop a mathematical model for microcirculation in LCCA, the present study adopted preexisted set of measured morphological data on anatomy, mechanical properties of the coronary vessels, viscosity of blood, the basic laws of physics, and the appropriate boundary condition. Pressures and volumes of blood and flow resistance were expressed in terms of electrical voltages, current, and resistances, respectively, in the electrical analog model. The results of two mathematical models, symmetrical and asymmetrical models, were compared with other investigator's data. The present results were in good agreement with previous studies. It was found that the mean pressure profiles were similar in both models.

In electrical machinery and apparatus, the most important problem is protect of machinery and apparatus in duo to transient phenomena and overload on operation. Particularly by advanced technology of late, there is demand for low cost of equipments and high percentage of use of equipments. Therefore, protection of machinery and apparatus in condition of overload is more valued considering that all efficiency increase is passed by operating all machinery and apparatus in condition of heavyload. In this paper, the suggested system is add overload protect system using CT in condition of overload.

Effect of liming material application on the prevention or cure of Mn toxicity symptoms including marginal leaf chlorosis in 3-year-old ginseng plants grown in acidic soils were investigated. It was found that the ratio of Fe to Mn was above about 0.5 and the ratio of Mn to Fe was below about 2.00 in 4-year old ginseng leaves when liming materials were applied in field experiments. It was apparent that the occurrence of marginal leaf chlorosis was decreasing affected by application of Ca, Mg and Fe. The appearance of marginal leaf chlorosis was decreased to about 78 percent in 4-year-old ginseng and to about 69 percent in 5-year-old ginseng, and then the fresh root weight was increased up to 66 percent in 4-year ginseng plants.

This study was performed to obtain the basic data for high quality timber production and efficient utilization by investigating the effect of pruning on timber quality of domestic plantation-grown Korean pine (Pinus koraiensis Sieb. et Zucc.). The results were summarized as follows:Dead knots (unsound knots) in the pruned logs occurred more at upper parts when compared with in non-pruned ones. The numbers of knots on surface in heavily pruned trees were less than those in non-pruned trees, but there was no significant difference in moderately pruned trees. The required period to reveal clear timber surface without defects after pruning increased proportionally with the increase of knot diameter. The yield of clear lumber production increased by about 10% after 14 years from moderate pruning. The quality grade of log improved with more pruning practices. Knots appeared the most important factor in lowering the log grades.
