In order to investigate effective method of the prevention of Frost-damage in the korean tea-plant, We sprayed plant-growth-regulators, NAA and Kinetin and MH and Gibberellin etc. on the leaves according to opportunity and density and established covering-materials according to material, and month, and so we could see the following results. 1. The districts were MH 1,000ppm and MH 2,000ppm were sprayed were to on extent of 24% more effective in reducing the Frost-damage than the districts where no chemicals were sprayed. 2. The most effective method of spraying chemicals was by doing at the beginning of passing the winter. 3. The district where Gibberellin 200ppm was sprayed had a reverse effect of 20% compared with that not sprayed. 4. The spraying of MH in October was more effective in promoting the persistency and preventing the defoliation of the seed leaves. than that of NAA. 5. In case Kinetin and MH were together sprayed, we could see some effect in the less densely sprayed district but not in the district where the highly densed Kinetin 500ppm and MH 2,000ppm were compoundely sprayed. 6. In the repeated spraying of chemicals in the sprouting-season, we could see the more effect in preventing Frost-damage caused by retarded-sprouting in proportion to their density and the breadth of district where chemicals were sprayed. 7. The district where Vinyl and Bamboo-blind-screen were together covered in september was to an extant of 20% more effective in preventing Frost-damage than that where only one covering material was covered.

1. The hair cells on adaxial surface turned out to be penetration way of Gleosporium Thea sinensis in tea plant, 2. The most parts of Gleosporium Thea sinensis generated in tea plant were young leaves with first-fifth leaves from tip of shoot. 3. The proper temperature for spore germination on leaf is 25-27℃, soaked by water for 12 hours. 4. For prevention of Gleosporium Thea sinensis the drug-spay in tea plant would be the most effective when sprayed at this temperature range, and the control of Gleosporium Thea sinensis would be possible through selection of tea plant with few hairs. 5. The treatment of bordeaux mixture to prevent growth of conidiospore was 48.3% more effective than in control plot which were not sprayed. 6. The effect of sprayed bordeaux mixture decreased to about 28.5% after one week of spray.

This study was aimed at expanding the tea plant culture in Korea to further north, and the leaf-form and the cold resistance of the tea plants selected form 7 districts(around Korea) were investigated. 1. The length of tea leaf is 5.1cm to 8.4cm, the width of the leaf is 2.3cm to 3.6cm, but the area of tea leaf in Mt. Mudung is 26.88㎠ and that is the widest of all. 2. The tooth number of the tea leaf in 43 to 73 but the number of Mt. Borim is remarkably number of all. The tooth number is increased or decreased in proportion to the leaf width and to the leaf length. 3. The lateral vein number is generally 13 to 19. The vein number of Mt. Borim is especially number of all. That is also increased or decreased in proportion to the leaf width and to the leaf length. 4. In general, the number of leaf formation index is 2 to 3, and ablong. 5. In general, those which come upper lands are remarkably small in length and width of the tea leaf and those which come from level lands are large. 6. All kinds of tea plant which is growing in Korea, area, are the same as those imported from China : Thea sinensis Linne var. Bohea. 7. I supposed that the external form of tea plant has a little changed by geography or climate for many a long day, since the tea plant had been transplanted in Mt. Samsin. 8. In the treatment of low temperature and duration of vernalization of their plants, those selected from Mt. Mudung and Mt. Hwaun were the coldest resistance, those from Mt. Samsin and Mt. Borim were medium and those from Mt. Joge and Nursery were codl sensitive. 9. The critical temperature of the tea plant from Mt. Mudung, Mt, Hwaum, Mt, Samsin and Mt, Borim was about -10℃, and that from Mt. Joga and Nursery was about -5℃. The critical temperature of frost injury of all tea plants in this experiments was -15℃ 10. In spite of increasing the vernalization time, the critical temperature was not effected, but the treatments over critical temperature were increased their frost injuries. Based on these results, the coldest resistance, Mt. Mudung tea plant, was considered expanding their culture to further north improvement yields of the tea plants in Korea

In order to substract the time and cost of propagation for inducing the haploid plants per each species. 500 anthers of late uninucleate microspore on early binucleate microspore stage of Robinia pseudoacacia (Fuel tree) Punius granatum (Ornamental tree). Aleurites fordii (Faty tree) and Styrax japonica (Silvicultural tree) were cultured on the modified Murashige and Skoog`s medium supplemented with Kinetin, 2.4-D and NAA as growth regulators. And I observed the samples of cultured anthers under the microscope which were made by Microtoming method and Paraffin method. The results were summarized as follows: 1) Among 500 cultured anthers per each species, anther numbers inducing the diploid callus were as follow: Styrax japonica 20 (4% for the species total); Aleurites fordii 10 (2% for the species, total) and Punica granatum 45 (9% for the species total) were showed. 2) 2n Callus were induced from anther wall. but haploid callus were induced from anther locule. 3) Haploid callus were induced only in 25 anthers (5% for the species total) of Robinia pseudoacacia. 4) These haploid callus were not originated from body cell of anther wall tissue, but from reduced microspores. 5) Since already reported many herbaceous haploid plants were induced from the callus which were originated from reduced microspores, I conclude that the anther of woody plant which induced the haploid callus also will be cultured haploid plant.

As mentioned above, most of the shelter-trees are Zelkova serata and Gingko biloba of between 500∼1000 years of age and mostly town and village-owned. And people have believed that many heavy old trees have guardian spirits in themselves and so people have prayed to them to the welfare and a good harvest of the village and riches and honors and the birth of a son and hereby they have cherished forests through this legend. Needless to say, this legend is nothing noresuperstition but the heavy-old trees are of great use directly or indirectly as valuable learng-data and as mark-trees of voyage and avenues and public-rest for the prevention as well. Besides the shelter-trees are not only the precious of the country but also the source of pride of the home-town and beautiful legacy and precious and cherished cultural assets. And so we should protect and preserve them well in order to be queath them to our long-distant descendants because they ire infinite source of life and they contain racial spirit and spirit.

Smaller enterprises begin on practical use to form integrated informational system on the inside of company according to development of internet and information techniques. The past days, it was managed mainly information system for the inside of enterprise, but in the present time, e-business between enterprise and enterprise, enterprise and customer, country and enterprise, ERP system, etc are activated. To construct the integrated informationalized system, smaller enterprices use the informational process strategy methods to analyze and evaluate the level of enterprise, construct the information infra and informationalized system. In this paper, 1 introduce the informationalized process strategy method about implimentation of the integrated informationalized system for smaller enterprice, do the modelling for one smaller enterprice by proposed method.

In this paper, we studied about method that instructor and learner execute teaching-learning activities and about the educational effects of a web based practice instruction. And, in practice instruction, we examined about role and influence of instructor, learner and manager. This study shows the method that instructor and learner execute teaching-learning activities and interaction activities in a "construction of e-business system" curriculum to support the informational education for an industrial workers. The research subject was the 15 industrial workers who enrolled a informational instruction coulee provided for two weeks by kimpo college, As a research method, workers survey, interview, and profile analysis were used for this study. The result of this study show that interaction between instructor, learner and manager was not executed actively, but the manner of lecturing about interest of learner, usage of email, question and answer of bulletin board, online-practice were brought an effect on interaction of learner activities and the educational effects.l effects.
