  • As to the up-lnd bamboos, I have reported, in my previous works, that Korea has two species in the genus of Pseudosasa, four in Pleioblastus, and other four in Sasa. In the present work, I dealt with Sasamorpha Purpurascens Nakai var. Borealis Nakai which proved the strongest vitality of all up-land bamboo yet found in various up-lands of Korea, and which might be most important from the utility view-point. This report is chiefly on its procreation. Sasamorpha Purpurascens Nakai var. Borealis Nakai can be found almost everywhere throughout the country, and its leaves and stems are much used in farms in various forms of manufacture. It is also welcomed as the feed for livestocks and as cover plants for aforestation, especially as the excellent means of errosion control on devastated hill sides. It is also widely accepted that it will provide, in the immediate future, abundant sources for the up-land bamboo pulp. As the first phase of my research plan on the subject, I undertook to determine the possible best way of its procreation, for which were included the experiments of inducing the growth of subterranean stems, the entire stand cutting, transplanting, reclaimed planting after burning etc. in order to observe the plant elongation, growing conditon, climatical effect etc. What has been fuond out so far given here as follows: 1) Of the various sections of the country, Mt. Odae area gives out the most excellent Sasamorpha Purpurascens Nakai var. Borealis Nakai(the leaf weight of which is 450 gr.) and Taekwanryong area comes the next class. This species can be transplanted anywhere in the South Korea. 2) The elongation of S.P. Nakai var. Borelais begins at around the middle of May and almost completely stops by the 20th of August. 3) The best studied transplanting season is supposed to be Feb. -April, for those transplanted during that period proved 100% of success. The next best transplanting season may be October. Rain fall does not have so much effect on transplanting as the growing season does. 4) In inducing the subterranean stems, the growing season can be ignored. The root expnsion is most animated during the months of April-June, the most active season for water absorption. Those stems induced during the winter proves more rapid growth. 5) The entire stand cutting shows greater growth than the reclaimed planting after burning and that, the growth is most vigorous during May-July, whereas during the hottest months of Aug-Sept. the growth shows only 5 cm. The new shoots grow slower both in the field of entire stand cutting and in the field of reclaimed planting after burning than in the otherwise fields.

  • 식물성지방산 고형비누는 검화법으로 제조 후 수분증발 및 경도를 위하여 건조과정이 필요하다. 본 연구에서는 합성향료를 대체하여 휘발성이 높은 에센셜오일을 혼합하여 비누 제조시 비누에 포함된 에센셜오일(라벤더오일)의 주요 향기성분(리나롤, 리나릴 아세테이트)이 건조기간 및 첨가물(이산화티탄)에 따라 변하는 향의 지속기간을 GC-MS를 이용하여 비교 관찰하고자 하였다. 그동안의 연구는 식물성고형비누의 사용성에 관한 연구가 대부분이었으며, 향의 휘발성과 관련된 연구는 미비한 상태이다. 비누에 포한된 리나롤의 휘발성은 이산화티탄을 혼합한 비누가 12주까지 감소율이 높게 나타났으나, 20주가 되는 시점에서는 유사한 수준으로 감소되었다. 리나릴 아세테이트는 이산화티탄의 혼합여부에 따라 약간의 차이를 보이기는 했으나 20주경과 시점까지 휘발성이 유사하게 나타났으며, 건조 20주 동안 리나릴 아세테이트보다 리나롤의 잔존율이 이산화티탄의 혼합여부와 상관없이 높게 나타났다. 상온에서 2일정도의 지속성을 갖는 라벤더 에센셜오일의 향 성분이 식물성 지방산 고형비누와 혼합하여 제조시 20주(5개월)동안 비누에 잔존하고 있음을 확인 할 수 있었다.

  • This study is proposed to research the rural clothing, dietary and housing style of living in order to adapt a basis which is supposed to improve the quality of rural life. The sample in this research comes from Daehang 1 Li, Bubuk Myun, Miryang Gun, Kyungnam, and the results are as following; Generally rural housewives are unconcerned with fashion or its information, instead, they care for the casual wear which represents economic and active life style. Because of their financial problems, inpurchasing, they spend only a small money without plan. When they launder Clothes, they use washing bat and pannel which is easy to break fabrics, and they ineffectively use to dry it by hands twisting. The total food intake per person in a day is 1170.6gram, and all nutrients intakes except fat and calcium exceed the recommended dietary allowances. But 90.3% of the food intakes are plant food, and the average food items taken per day per househod is 11.9items which are not so various, which represents the shortage of the nutrient quality. Both the nutrition knowledge score and the food habit score are very low. Therefore, in order to enhance the quality of clothing and diet in rural life, they need to learn clothing and nutrition management for their enlightment. The most comprehensive type of farmhouse site plan take the shape of ㄱ and ㄴ, and for the most part main building is the floor plan which includes 3-4 spans in front of the change from the type of traditional house, throught the revised one, to the type of newly built house. In main building of the farmhouse, kitchen, Kunbang and Chakunbang are extended to their real space, and both utility and the bathroom are added to build, and Malu is transformed into the living space.

  • In order to evaluate the utility of the anthocyanin pigments in Ganges Amaranth as an edible pigment, this study was designed to isolate and identify the anthocyanins. The anthocyanins present in leaves of Ganges Amaranth were extracted with 0.1% HCl in methanol. The extracted pigments were purified by organic solvent treatment and Amberlite CG-400 Type cation exchanger, and then separated into individual pigments by paper chromatography with n-butanol-formic acid-water(100:25:60, v/v) as a solvent system. The separated pigments were identified by their Rf values, sugar moieties, complete hydrolysis and spectral characteristics in the visible and ultraviolet regions. The amounts of individual anthocyanins were also determined. The results obtained from these experiments were as follows. 1. Chromatograms of the Ganges Amaranth extract developed with BFW yielded three anthocyanin bands. The two of the anothocyanin bands were tentatively identified as malvidin-3-glucoside(acylated with caffeic acid) in band 1 and peonidin-3-glucoside (acylated with caffeic acid) in band 2. But the anthocyanin in band 3 was not identified due to extremly low concentration. 2. The amount of total anthocyanins was 101.57 mg/100g fresh weight of leaves in which 82.15 mg of malvidin-3-glucoside (acylated with caffeic acid) and 27.20 mg of peonidin-3-glucoside(acylated with caffeic acid) were contained per 100g fresh weight. Maividin-3-glucoside acylated with the acid was, therefore, the most abundant pigment in the Ganges Amaranth.

  • Due to limited supplies and expensive importing costs, it is a goal to replace overseas peat with local soil amendments in turf industry of Korea. The study was initiated to compare the performances of five domestic and imported organic soil amendments (OSAs) on establishment characteristics and to provide basic information for root zone composition on sports turf design and construction. The study was conducted in Kentucky bluegrass (Poa pratensis L., KB) under greenhouse conditions from March to June in 2008. A total of 25 treatments of OSA + sand were prepared. These amendments were Berger Peat (OMA), Eco-Peat (OMB), G1-Soil (OMC), Premier Peat (OMD), and Supersoil I (OME). Significant differences were observed in establishment vigor, seedling emergence, and top growth. Results varied depending upon the type of OSAs and their rates in rootzone mixtures. OMA reached over 70% in establishment vigor in 5 WAS (weeks after seeding). OMC produced a maximum vigor of approximately 60% in 6 WAS. The OME amendment, however, showed poor performance lower than 30% in establishing KB turf until 8 WAS. There were considerable variations of top growth, being 3.8 to 14.5 cm. Greater differences in top growth resulted from OME mixtures. Shoot growth orientation in KB is also influenced by OSAs. In general, optimum mixing rate was considered as 10 to 20% for establishment vigor and 20 to 40% for top growth. Considering overall responses to establishment vigor, seedling emergence, and shoot growth, both local OMC and overseas OMD are considered as the useful soil amendments applicable for sports turfs. Domestic OME amendment would be applied for a low maintenance turfs such as rough and utility areas due to greater shoot growth. Information on these amendments would be of practical use for sports turf design and construction. Repeated experiments and field performance test are required to evaluate these OSA effect on other major turfgrass species and also to determine local OSA as imported peat substitute.

  • Soybean seed ferritin is essential for human iron supplementation and iron deficiency anemia prevention because it contains abundant bioavailable iron and is frequently consumed in the human diet. However, it is poorly understood in regards its several properties, such as iron mineralization, subunit assembly, and protein folding. To address these issues, we decided to prepare the soybean seed ferritin complex via a recombinant DNA approach. In this paper, we report a rapid and simple Escherichia coli expression system to produce the soybean seed ferritin complex. In this system, two subunits of soybean seed ferritin, H-2 and H-1, were encoded in a single plasmid, and optimal expression was achieved by additionally coexpressing a team of molecular chaperones, trigger factor and GroEL-GroES. The His-tagged ferritin complex was purified by $Ni^{2+}$ affinity chromatography, and an intact ferritin complex was obtained following His-tagged enterokinase (His-EK) digestion. The purified ferritin complex synthesized in E. coli demonstrated some reported features of its native counterpart from soybean seed, including an apparent molecular weight, multimeric assembly, and iron uptake activity. We believe that the strategy described in this paper may be of general utility in producing other recombinant plant ferritins built up from two types of subunits.
