배추(Brassica campestris ssp. napus var. pekinensis)의 캘러스 배양을 통한 식물체 재분화
이숙이,박민철 가톨릭대학교 자연과학연구소 1998 자연과학논문집 Vol.19 No.-
배추(Brassica campestris ssp. napus var. pekinensis)의 기내 조직배양에서 캘러스 형성 및 식물체 재분화에 미치는 생장조절제의 영향과 AgNO₃의 효과를 조사하였다. ‘삼진’과 ‘서울’ 배추를 이용하여 발아 6일된 유식물의 자엽과 배축으로부터 캘러스를 유도하였다. 캘러스의 형성은 배지에 함유된 2,4-D 농도에 의존적이며, 1㎎/ℓ 2,4-D와 0.1㎎/ℓ kinetin을 동시에 처리하였을 때 가장 잘 형성되었다. AgNO₃를 처리한 경우 50μM의 농도에서 가장 높은 생체량 증가를 일으켰으며 갈변 억제효과와 절편체 생존율 증가를 나타내었다. BA와 NAA를 조합 처리한 재분화 배지로부터 shoot가 분화되었는데, ‘삼진’ 자엽 유래 캘러스는 5-9㎎/ℓ BA와 0.1-0.5㎎/ℓ NAA 농도로부터 shoot가 분화되었으며, ‘삼진’ 배축 유래 캘러스로부터는 shoot가 분화되지 않았다. ‘서울’ 자엽 유래 캘러스는 3-9㎎/ℓ BA와 0.1-0.5㎎/ℓ NAA 농도로부터 shoot가 분화되었으며, ‘서울’ 배축 유래 캘러스는 1-9㎎/ℓ BA와 0.1-3㎎/ℓ NAA 농도로부터 shoot가 분화되었다. 형성된 shoot는 0.1㎎/ℓ NAA를 함유하는 MS배지로 옮겨진 후 10일 이내에 뿌리가 형성되어 정상적인 식물체로 생장하였다. The effects of growth regulators and AgNO₃ on callus formation and plant regeneration have been investigated. Calli were induced from the hypocotyl and cotyledon explants of 6-day old seedlings. Calli were induced most frequently in the MS basal medium containing 1 mg/1 2,4-D and 0.1 mg/l kinetin. Callus growth rate and explant survival rate were most enhanced at 50 μM AgNO₃, and callus browning was inhibited at the presence of AgNO₃. Shoots were formed on the regeneration medium supplemented with BA combined with NAA. Shoots were formed on the medium supplemented with 5-9 mg/l BA and 0.1-0.5 mg/l NAA from the callus derived from cotyledon explants of cv. Samjin, but hypocotyl explants were not regenerated. Shoots were regenerated with 3-9 mg/l BA and 0.1-0.5 mg/1 NAA from the callus derived from cotyledon explants of cv. Seoul, and 1-9 mg/l BA and 0.1-3 mg/l NAA from the callus derived from hypocotyl explants of cv. Seoul. Shoots were transferred to the MS medium supplemented with 0.1 mg/l NAA, and roots were formed within 10 days, and grew into normal plants.

The purpose of this study was to investigate disinfection state and effective factors of foodservice facilities and utilities of elementary schools in Busan area. Foodservice facilities and utilities investigated in this study were ceiling, wall, floor, trench, greasetrap, hood, pest and dumb waiter. The questionnaire which was administered to 196 dietitians was used as a survey method. The results were as follows. The washing method of foodservice facilities and utilities was mainly used by detergent washing-natural dry. The disinfection method of foodservice facilities and utilities was mainly sanitized by sodium hypochlorite. Dumb waiter and hood were sanitized by 70% ethyl alcohol and iodine. In washing and disinfection frequencies of foodservice facilities and utilities ceiling was twiceiyear, wall, hood and pest control facilities were once/week, floor, trench, greasetrap and dumb waiter were everyday, respectively. Floor, trench, greasetrap and dumb waiter were disinfected properly, whereas ceiling, wall, hood and pest were not disinfected properly. The washing method was related to dietitian's marital status and education. The disinfection state was related to dietitian's age and career, having of sanitation check list. The disinfection method was also affected dietitian' s marital status, number of employee, duration of foodservice, number of total serving and having of sanitation check list. Therefore based on the results of this study, it should be given to the microbiological study on disinfection of facilities and utilities such as ceiling, wall, floor, trench, greasetrap, hood, pest and dumb waiter and the dietitian and employee's sanitation training also should be conducted continuously.

To observe the developing process of human fetal eccrine sweat gland during the intrauterine life, an electron microscopic study was carried out based on 12 fetuses ranging from 20 to 42 weeks of gestation. These fetuses were the products of induced deliveries found to have not associated disease or congenital anomalies at the autopsy. Following observations were made. The various types of cell consisting coiled portion of eccrine sweat gland were recognized at the 20th weed of gestation and they were clear cells, undifferentiated dard cells, myoepithelial cells. clear cells were located in central central portion and dark or myoepithelial cells were in peripheral portion. While undifferentiated dark cells were randomly distributed in the straight portion of eccrine sweat gland. The differential points between clear cell and undifferentiated dark cell were its round nucleus and glycogen contents. Marked hydropic changes of clear cells were noted at the 30th week of gestation. Secretory granules were noted at the 31st week of gestation. Secretory cells in the coiled portion of eccrine sweat gland was not fully mature until the 42nd week of gestation. Clear cells showed clear cytoplasm, abundant free ribosomes and scanty organelles. Undifferentiated dark cells showed many mitochondria and few glycogen. Secretory granules were rarely seen. Myoepithelial cells showed a few mitochondria, glycogen and microfilaments. Among three portions of eccrine gland, duct lumen in the acral and coiled portion were formed through the intracellular canaliculus and in the straight portion were made through the intercellular canaliculus. The main basic morphological mechanism of the lumen formation were microvesicle formation and pinched off phenomenon.

Yi, Gi-Hwan,Park, Dong-Soo,Chung, Eun-Sook,Song, Song-Yi,Jeon, Nam-Soo,Nam, Min-Hee,Kim, Doh-Hoon,Han, Chang-Deok,Eun, Moo-Young,Ku, Yeon-Chung The Korean Society of Crop Science 2006 Korean journal of crop science Vol.51 No.6
It is important to understand pedigree of rice cultivars commonly used for breeding. In this paper, pedigree tables for tracking the pedigree of 17 representative rice cultivars recommended by Rural development Adminstration (RDA) were completed and analyzed using two kinds of web database system; 'IRIS' and 'RRDB'. Seven cultivars, namely, 'Sangmibyeo', 'Ilpumbyeo', 'Saegewhabyeo', 'Surabyeo', 'Shindongjinbyeo', 'Ilmibyeo' and 'Jungwhabyeo' had 'Koshihikari' on the pedigree of their ancestor. Besides 'Koshihikari', the most feguently used ancestral germplasms among the high quality rice cultivars were 'Fujisaka 5', 'Kameno o' and 'Asahi', 'Fujisaka 5' was used as ancestral parent in 12 out of 17 cultivars. Interestingly, 'Kameno o' was used in pedigree of 16 out of 17 high quality varieties and 'Asahi' was used in the ancestral pedigree of all 17 varieties. 'Hwayeongbyeo' was used as one of parent in the breeding of 'Dongjin 1', 'Hwabongbyeo', 'Saegewhabyeo' and 'Junambyeo'. 'Ilpumbyeo' was used in the breeding pathway of 'Junambyeo' and 'Saegewhabyeo', 'Mangeumbyeo' itself was not enlisted as one of high quality rice cultivars, but was used as a breeding parent of three high quality varieties, namely, 'Saegewhabyeo', 'Hwabongbyeo' and 'Nampyeongbyeo'. Incorporated with evaluation data, pedigree will provide a valuable chance to genealogical tracking of agronomic traits such as disease resistance, grain quality and etc.

Since the economic crisis in 1997, the Korean government has implemented a number of reforms in order to eliminate inefficiencies in both private and public sectors. One of the reforms made in the public sector was to lower the retirement age of teachers from the original age of 65 to that age 62. The ultimate aim of this compulsory policy was to improve the quality level of education by hiring many young teachers instead of senior teachers. It was made based on the calculation that by lowering the retirement age by three years, the government can hire three young teachers with the saved wages. However, this policy has brought an unexpected result; the imbalance between the supply and demand for teachers has become a much more serious problem in Korea's elementary education system The purpose of this study is largely twofold; First of all, it aims to identify the scope of imbalances occurred in the supply-demand system of elementary school teachers in a region of the nation, and also to find out why such imbalance occurred. Secondly, the purpose of this study is to experiment with feasible policy alternatives and their effects on the system and to suggest some resolutions on the imbalance.
