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.

우리나라 환경영향평가제도의 문제점과 개선방향

홍금우,정성윤 朝鮮大學校 2003 經營經濟硏究 = Management and economics research Vol.26 No.1

This research is to point out problems and improvements about the present system of environmental impact assessment in Korea. Environmental impact assessment is an integral part of a decision-making process for a development project. But There are some problems in this system. So this paper presents a number of policy alternatives which environmental impact assessment can be improved First, an Environmental Impact assessment report should be prepared by the fair and objective person not developer. Second, Environmental Impact assessment system is not enough, so screening system and seeping system should be added to it. It need to reinvented so as to include a practical alternative investigation. Third, comprehensive environmental information system on the regional and national levels should be established ton provide necessary information prior to Environmental Impact Assessment. Fourth, Environmental Impact assessment time and participation of regional residents is not enough.

In Modern society, we feel keenly the necessity of understanding and knowing for the bills and checks as a means of payment remittance. In this paper, we consider the comprehension(conception and kind) of bills and checks, and investigate the requisite for drawing bills and checks in the law of securities. In particular, we distinguish the formal conditions(acting signature) and essential conditions(available intention), and we apply the rules of civil law to rules for issue which has no in law securities(Law of bills and checks).

In order to study the sickness prevalence and kinds of sickness among rural populace in plain areas of this country, surveys were conducted on 1,024 households comprising 5,679 persons during a one-month period of January 1 to 31, 1969. Through the analysis of the results, the following conclusion was reached: 1) The age composition of population subject to the surveys showed a typical pyramid style. The group of 0 to 9 years of age constituted 26.2 per cent of the total population which underwent the surveys. Proportion gradually decreased as age increased. The age group of 60 years or more showed 6.4 per cent or the smallest proportion. 2) By education, the population subject to the surveys was broken down as follows: Primary school graduates constituted 25.9 per cent of th total number of persons; those currently attending primary school 18.9 per cent; those yet to attend (not applicable) 17.4 per cent; those barely able to read Hangul (Korean Alphabet) 11.3 per cent, and illiterates 11.0 per cent.
