Aims of this study were carried out to develop the useful lines induced from mutation and pedigree breeding methods among the collected genetic resources from national and domestic areas. In this study, Stem height of CNU126 line and check among them were high, while CNU128 was lower than other lines. Spiklet length of CNU88 was longer, but that of CNU126 was shorter than check. Number of spiklets per plant of CNU50 among lines have twice time than check. 1,000 grains weight of CNU113 was higher than check. In yield per plant, CNU50 and CNU112 were higher than check, Dongjinbyeo.

For mass product of nanocrystalline ZnO ultrafine powders, self-sustaining combustion process(SCP) and ultrasonic spray combustion method(USCM) were applied at the same time. Ultrasonic spray gun was attached on top of the vertical type furnace. The droplet was sprayed into reaction zone of the furnace to form SCP which produces spherical shape with soft agglomerate crystalline ZnO particles. To characterize formed particles, fuel and oxidizing agent for SCP were used glycine and zinc nitrate or zinc hydroxide. Respectively, with changing combustion temperature and mixture ratio of oxidizing agent and fuel, the best ultrasonic spray conditions were obtained. To observe ultrasonic spray effect, two types of powder synthesis processes were compared. One was directly sprayed into furnace from the precursor solution (Type A), the other directly was heated on the hot plate without using spray gun (Type B). Powder obtained by type A was porous sponge shape with heavy agglomeration, but powder obtained using type B was finer primary particle size, spherical shape with weak agglomeration and bigger value of specific surface area. 9/ This can be due to much lower reaction temperature of type B at ignition time than type A. Synthesized nanocrystalline ZnO powders at the best ultrasonic spray conditions have primary particle size in range 20~30nm and specific surface area is about 20m$^2$/g.

Pd / Al2O3 의 Fluorination 이 CFC - 113 a 수소화 반응에 미치는 영향

The effect of fluorination over Pd/Al₂O₃catalyst have been investigated in the hydrogenation of CFC-113a. Fluorinated Pd/Al₂O₃(F-Pd/Al₂O₃) catalysts showed higher conversion of CFC-113a than Pd/Al₂O₃catalysts. Fluorination treatment, from the characterization of used catalysts by XRD, TEM and EXAFS, prevented sintering of palladium particles during reaction and some parts of palladium formed a matallic state palladium as well as fluorinated Pd(Pd-F) upon fluorination. The Pd-F bonding suggested strong interaction with support which can decrease the sintering of Pd particles during reaction. Simultaneously, it was also comfirmed that γ-Al₂O₃ phase changed to AlF₃ and the surface area decreased after fluorination process.

한약재 품질관리실태에 대한 한방의료기관 종사자들의 인식도

This study was conducted to examine recognition of oriental medical doctors on the quality control of herbal medicine and to provide useful information for the establishment of effective quality control system of herbal medicine. Data were collected from 202 oriental medical doctors working in oriental medical hospitals or clinics in Daegu-Gyungbuk province. Generally, there is a tendency that most respondents have low degree of recognition, trust and satisfaction of the quality control of herbal medicine while they think standardization and complete quality control systems of herbal medicine is needed highly. Thus, in order to increase confidence of consumers in herbal medicine, and to increase the utilization of oriental medical services, both strengthening of quality control systems and standardization and establishment of Oriental KFDA as a new government agency responsible for the work should be required.

경주 광명동유적 건물지의 성격에 대하여

It was identified by the excavation that architecture remains were confirmed buddhist temple consist of ruins of main building of a temple, auditorium site, ruins of stone pagoda, embankment, pedestrian Facilities and drainage etc. in the Gwangmyeong-dong site. The site has been held temple arrangement with 1 main building of a temple, twin Pagodas from the Unified Silla period to Goryeo dynasty. The temple constructed after that was destroyed the architecture in the Unified Silla period. It seems that aristocrat or royalty power of within group of the nearby remains of city which was constructed in the Unified Silla period build and visit the temple. Considering there are excavations, it assumes that the temple had been constructed during the last days of the Unified Silla, was closed up during the mid-Goryeo Dynasty.

케냐의 언어정책과 국가정체성의 관계 : 스와힐리어 정책을 중심으로

김광수(Kim Kwang-su) 한국아프리카학회 2011 한국아프리카학회지 Vol.33 No.-

Language renders a symbolic identity and ideological framework to a community. In the case where the language is selected by either the nation or the government, a creation of a new identity or a national identity is asked for. Hence, it can be said that the establishment of language urges the development of civilization and national society in a historical respect. Like the majority of nations in Africa, Kenya uses English as their national language for education and international communication, while designating Swahili, the dominant language in East Africa, as their native language. Moreover, Kenya uses 20 out of 40 languages as its native language, thereby hampering a regulation of unity in language. Ultimately, an abstract policy of language can be blamed for obstructing the unification of citizens, resulting in a failure of cultivating a national identity. The situation in Kenya has proved that promoting multiple languages as one’s mother language impedes the development of a single language policy. A definite ideological background or correlation does not exist concerning Kenya’s attitude of non-interference towards its language policy. Indefinite attitudes of government officials and actions to exploit the identity of a nation for the government’s benefit have basically caused the failure in controlling its language policy, with no plans for reformation. In my view, national identity has been deprived, while communal identities have been more firmly established.

아프리카의 구전전통에 나타난 역사의식과 문화적 정체성 : 남부 아프리카의 구전역사가 임봉기(Imbongi)를 중심으로

김광수(Kim Kwang-Su) 한국아프리카학회 2004 한국아프리카학회지 Vol.20 No.-

This article offers the role and function of Southern African imbongi as a oral historian(in particular Zulu and Xhosa society). They are reciting a praise-poem(izibongo) as the public orators or praise poets in the official places and out in their colourful dresses dancing and singing. Izibongo is the genre of fundamental historical, political, and socio-regulative relevance, and interpretation which within Zulu and Xhosa societies seems to have been continually valid until today. Attached to the court of the king or chief was an important official whose profession was the recording of the praise-namse, victories, and laudable characteristics of his master. These izibongo were recited on any occasion which seemed to call for public adulation of the chief, such as the defeat of his enemies, the approach of distinguished visitors, the distribution of royal bounty, and so forth.
