  • In this paper discusses winding methode of single phase AC-DC reversible power converter The reversible power converter driven by multi Tap winding at both side switching control. It has a advantage that simple drive of main switching device. and obtain load current of good quality without filter circuit and free from noise or isolation for lower switching frequency. In this research, study on current type converter and inverter circuit that consist for possibility of AC-DC/DC-AC multi-level reversible converter.

  • This paper describes a new speckle noise reduction methode on the sonar image using TVG Filtering and PDF wavelet transform. The speckle noise makes the degrading image to discriminate the various object on the ocean bed. The TVG filter removes the speckle noise by gain with observing the results timely and inductively. The experimental result is that speckle noise is reduced to 90 %. Thus the proposed technique leads the mage recognition to be enhanced in the submarine environment.

  • The Siuejunsuh is a book of Korean woman's life in the Yi-dynasty which published late in 18 century by unknown author. I have studied the food habits of the Yi-dynasty that wrote in siuejunsuh as following. The staple foods ae Bab (boiled cooked rice) 2, Juk(gruel) 6, Mieum(thin rice gruel) 3, Uee (liquid) 1, D'ockguk 2, Mandu3 Kinds I this book. the side dishes are Guk(soup) 24, Jochi 7, jungol 2, J'im 16, Sinsollo 1, Bockuem 5, Sun 6, Gui 16, Jock 10, jon 12, jorim 7, Namul 14, Sangchae 4, Hyae 17, Joban 2, Nooruemi 1, Sooranpoached egg) 2, Sondae 2, jockpyun 1, Choe 1, Muchim 11, Pyunuk 2, Jockgall 6, Po 9, Ssam 4, Jup 1, Jangaji 27, Kimchi 20, and other 27 Kinds. the desserts are D'ock 41, jabgwa 52, Beverages 17 kinds. the alcohol and frutie liquor are 18 kinds. The seasonings are soybean sauce, Jinjang, red peper bean paste, Zupjang, Dampukjang, Chunggukjang, honey, vinegar, mustard, Yunzup etc. Storage foods are vegetables,fruits and beans etc. There are 62 kinds of table ware and cooking kitchen utensiles, but many of them came to usefulness. 16 kinds of measuring unit are very non-scientific because that is not by weight but by bulk or volume. Thee are many food making terms which are 179 kinds of prepared cooking term, 22 kinds of cutting term and 16 kinds of boiling term. And 20 kinds of expression of taste can be seen in this book. Food serving methods are D'ockiserving method, fruits and dried food serving methode in chanhap (food packed in a nest of boxes) Guksoo serving method, Jock serving method, fruits serving method, Seup serving method etc. Table setting methods ae 9 sets of dinner, 7 sets of dinner, 5 sets of dinner, side table setting, liquor table setting, Sinsollo table setting, food's dab table setting etc.
