This study analyzes on the manufacturing of the Korean traditional flute, Geum. The major findings are as follows: (1) Including Hyungeum, Gayageum and Bipa, Geum is one of the Korean traditional musical instruments which have been played early since the period of King Yuri in the Shilla Dynasty. (2) Geum is classified into three types, referred to as Daegeum, Junggeum and Sogeum, and each one can be played on 324, 245 and 298 kinds of melody. (3) There are various styles for playing Geum, for example, the Akhakgwebeom published by Seong Hyeon and others, describes seven ways of fingering. (4) The manufacturing of the Korean traditional Geum has almost disappeared because of some reasons, like differences in scale between eastern and western music, and problems in making a livelihood. (5) I try to restore the way of manufacturing the Korean traditional Geum with Kim Tae-Hyeon who is a master craftsman and a player of Daegeum, referring to the way of manufacturing Geum described in the Akhakgwebeom.

The taxonomy of the species of the family Bagridae from Korea is reviewed and the keys to the following eight species of Korean bagrid fishes are presented: Pelteobagrus fulvidraco (RICHARDSON), P. nitidus (SAUVAGE and THIERSANT), Pseudobagrus ussuriensis (DIBOWSKY), Ps. sp. UCHIDA, Leiocassis longirostris GU¨NTHER, Coreobagrus brevicorpus MORI, Liobagrus andersoni REGAN, and L. mediadiposalis MORI. Among them P. nitidus, previously known only from Chinese waters, is firstly recorded from 26 specimens collected mainly off the lower course along the Geum River in the present study. Comparison with P. vachelli of which many paper have recorded from Korea, shows that P. nitidus differs from it in number of gill raker(9-11) and in the short length of its maxillary barbels. The 36 bagrid specimens, which were collected in the Han and Geum River in this study was identified as Pseudobagrus ussuriensis of which the species identification was not confirmed formerly in Korea. The critical examinations of the specimens and the previous discriptions refered to Ps. ussuriensis and Ps. emerginatus SOWERBY (Not REGAN) revealed that Ps. emerginatus mostly used in Korea is a synonym of Ps. ussuriensis. Ps. sp. UCHIDA is clearly distinguishable from other twelve relative species of the genus Pseudobagrus on the bases such as the length of maxillary barbel, serrate structure on the anterior part of pectoral spine, and several morphometric characters. Therefore Pseudobagrus sp. is regarded as a valid species. The six atypical specimens of the genus Liobagrus collected in the Geum River are considered to be natural hybrid between L. andersoni and L. mediadiposalis on the basis of the length of jaw and of the number of feeble teeth on the posterior part its pectoral spine. Interspecific relationships were investigated in the species of Korean bagrid fishes on the basis of the features of the morphological characters and the pattern of aqueous soluble muscle protein.

PLC system is used for the purpose of decentralized control and allows data transmission between programable controllers to be easily performed by using an exclusive relay area. The programming language is important to operate the system. In this paper, it is used SFC(Sequence Function Cahrt) programming language to decrease the execution time with compare the ladder diagram program method. As a result, the SFC programming language process time is faster about 20∼30(%) than the ladder diagram programming.

Recently, the environmental load has rapidly increased with the burgeoning of world population and the great expansion of severe global environmental issues. Therfore, it is inevitable to develop technology to ensure a stable clean energy source to replace oil as well as energy saving technology. Under these circumstances, photovoltaics (elecric power generation directly from sun light using solar cell) have attracted world-wide attention because of its cleaness. This paper reviews photovoltaic measurements on the refernce conditions and reference cell mothod and studies photovoltaic devices on the performance measurement and evalution procedures. Especially, activation of the photovoltaic researches and industrialization are emphasized in this paper.

To optimize the preparation process of Jeung-Pyun, an experiment was derived, using a central composite design, to find the optimal mixing conditions. The addition of Paecilomyces japonica powder, the volume of Tak-Ju and the second fermentation time were independent variables, with the pH, volume, color, sensory and texture properties of the Jeung-Pyun selected as response variables. As the Paecilomyces japonica powder and fermentation time were increased, the b values and volume after the second fermentation also increased. The color of the Jeung-Pyun became deeper with increases in the Paecilomyces japonica powder and fermentation time, and was deepest on the addition of 30% Tak-Ju. The pH increased with increasing fermentation time of the Jeung-Pyun, and on the addition of 3% Paecilomyces japonica rapidly increased more than with the other groups. The optimal mixing conditions for the best quality Jeung-Pyun, with restricted conditions above a b value of 3, a color intensity above 3, and a volume of 40㎖ and a pH of 4.02~4.04 after the second fermentation, were 4.0%, 20% and 45 mins for the Paecilomyces japonica powder, Tak-Ju and second fermentation time, respectively.

韓國家族制度에서 戶主權과 戶主承繼制度의 新法과 舊法과의 比較硏究

박금철 경원전문대학 2000 論文集 Vol.22 No.-

The patrilocal family headship has become the mainstay of the Korean family law, forming the framework of the family law in Korea. The eldest son in any family unconditionally and compulsorily succeeded to the legal staus of the family head, which was called the family headship inheritance system. But it was amended into the voluntary family headship succession system. The scope of relatives was transformeal blood relative system. Consequently, the concept of the rules and regulation of the patrilineal blood relative system has much been weakened. As the compulsory family headship inheritance system in the old law was transformed into the voluntary family headship succession system, the accompanying rights and obligations were muchcurtaled. In consequency, the family headship system under the new law was indeed converted into the nominal system. Therefore, this study was intended to make a comparative investigation into what difference there was in the headship of a family headship succession system between the old family law and the new family law. To assist in understanding it, it provided an explanation of terminology in the family system, the family head's rights and obligations under the old family law and those under the new family law. And it offered an comparative expanation of the revised bill submitted to the National Assembly and its revised alternative of the legislation and Judiciary Committee, and it focused its attention helping people have an interest in and understand the family law by introducing the public opinion and scholars' opinions on the revised family law.

The objectivesof this study were to investigate quality characteristics of Yukwa which containing 0, 1, 3, 5% of safflower chemical properties showed that degree of expansion of Yukwa were decreased as the amount of safflower increased, while fat absorption increased. Fatty acid of Yukwa were increased as the amount of safflower increased. Sensory properties showed that cripsness of Yukwa were significant difference(P<.001) in the Yukwa with Safflower. L-value decreased by the addition of safflower, while a-value and yellowness increased. The mechanical properties showed that hardness and brittleness was the highest in the Yukwa with 5% safflower. Later 4 weeks and 6 weeks of storage, 3% and 5% safflower containing Yukwa showed decrease peroxide value and acid vale. respectively.

The three-phase induction motor is rugged, reliable, long-lived, self-starting, smooth-running. But it is relatively inexpensive and three-phase power in not available everywhere, so if possible we need single-phase motor with the same characteristics. In fact, single-phase induction motors have excellent characteristics and outnumber the three-phase variety. Most of the small electric motors used in home, farm, or office are single-phase induction motors of one type or another. This electric motors application field need most energy saving type drive according to enlargement of electronic goods and to tend high class. The paper is proposed a various phase control methods for energy saving of single- phase induction motor. The controllers that are embodied by each method can use by various usage according to each performance and it is considered that application may help in the electrical energy saving because is possible to other electrical appliances.
