Kimchi has been worldwide recognized as a traditional Korean fermented food, In the Chinese cabbage's pickling, salt content of evenly penetrate into the tissue affects on the texture of matured kimchi, But the previous method which usually using brine salting has a disadvantage of uneven penetration of salt into the leaves and stems. The purpose of the study is to develope the method which produce superior kimchi by evenly penetrate the salt into the tissue rapidly, The dry salting method is directly spread the salt on the surface of chinese cabbage as percentage in weight with 10, 12, 14, 16%(s) and pickled in this state for 5 hours. Brine salting method is soaking chinese cabbage in the 16% salt solution(16%B) for 20 hours. Sensory evaluation, contents of salt, properties of mechanical hardness and micro structure were studied among fresh cabbage, 16%B and 10, 12, 14, 16%(s) cabbage, The result of salt contents in all groups of pickled chinese cabbage were significantly increased compared with fresh cabbage. The compressive force of cabbage's steams by mechanical measurement was significantly decreased but cutting force was increased. In pickled cabbage, the cutting force was the highest correlated with salt content, In the sensory evaluation, the salty taste of leaves and chewy degree were significantly increased, but the hardness and crips of the stems were significantly decreased by increasing salt contents. Therefore the dry salting is the most excellent pickling method in small amount of kimchi production by saving salt amount and time, furthermore due to even penetration of salt into leaves and stems.

Tamarix chinenis blooms twice a you and its flowers, branches and leaves make the adjustment of tree shape. Propagation methods and growth characteristics of T. chinensis were studied in order to ascertain its potential use as one of vegetation resources for coast forestation and landscaping. The study results indicated that 1 or 2 you old hard wood cuttings showed higher rooting ratio than greenwood or semi hard wood cuttings. One to one mixture between vermiculite and pearlite appeared to be the best for bed soil, and sea sand and silt(loess) mixture was the next. Sea sand and granitic soil followed after. In terms of seasonal differences, spring cuttings showed the best rooting ratio, root number, and root length. Fall cuttings followed after spring cutting, and summer cuttings showed worst results regarding rooting ratio, root number, and root length. The best rooting promotion effects of growth regulators were observed with sea sand bed soils. There was no significant difference among growth regulators in terms of rooting and shoot growth. Low concentration below 100 ppm of growth regulators was enough for rooting promotion effect. In general, the number and mean length of roots and shoots were showed the excellent records in the sites with high rooting ratio. The study result strongly showed that T. chinensis can be considered as a suitable tree for coast forestation and landscaping because of its easy cutting propagation and rapid growth on saline lands.

This study was carried out to investigate the labor saving cultivation of C. auriculatum, which has much bigger root than local variety C. wilfordii, and tested three nonsupporting methods, i.e., untreated control, top pinching, and cutting of branch-top compared with I type stake. Top growth was more vigorous in staking cultivation than in nonsupporting cultivations. Among nonsupporting methods, main vine length and total length of main vines per plant were increased in order of untreated control > top pinching > cutting of branch-top, while the opposite is true to diameter of main vein. Number of leaves per plant was lower, but leaf length and leaf width were higher in cutting of branch-top than in other nonsupporting methods. Number of branched root and diameter of main root were bigger in cutting of branch-top and in staking cultivation, while length of main root and diameter of branched root were greater in staking cultivation and in top pinching than in other treatments. Although yield of marketable root per 10a was $17.9{\sim}22.6%$ lower, income was $8%{\sim}17%$ higher in nonsupporting methods than in staking cultivation by cost saving to staking installation. Among nonsupporting methods, yield of marketable root and income were 6% and 8% higher in cutting of branch-top than in untreated control, respectively.

The objective of this study was to establish the optical storage condition in cutting slips of Lycium chinense Mill. We investigated the different influential growth factor of this plant including two soil types (soil and vermiculite) and storage methods (gauze, parafilm, vinyl, and paper). Our result revealed that the formation of axillary bud was highest ($4.8{\pm}0.75ea$) from the cutting slips stored in vinyl and vermiculite treatment. Root length was long ($2.8{\pm}0.13ea$) in parafilm storage using soil. Maximum plant height was $135.33{\pm}12.81cm$ with gauze storage using vermiculite. The number of leaves was maximum ($130{\pm}2.5ea$) at 90 days from the cutting slips of gauze storage using vermiculite. Highest number of fruit was harvested ($149{\pm}16.05ea$) from the cutting slips stored in parafilm and grown in vermiculite. It can be concluded that the storage treatment and soil type influence the affecting to general growth of Lycium chinense Mill.

These studies were carried out to investigate seed propagation method and conducted using stem cuttings of Styrax japonicus for using as a woody landscape plant. The results are obtained as follows. After the H\sub2\SO\sub 4\ and GA\sub 3\ treatment to the seeds of Styrax japonicus, three months of warm treatment followed by cold stratification for four months increased seed germination rate. The rooting rate of Styrax japonicus was increased by the treatment with concentrated IBA, especially highest at 7,000ppm. Rooting percentages were highest for cuttings taken on July 15, 1995. Therefore, the most effective method for rooting of Styrax japonicus was treatment with 7,000ppm IBA on July 15 cuttings, which showed rooting rate of over 90%. Half-leaf-remained cuttings were more effective than those with two leaves on rooting of Styrax japonicus. Dipping for 10 seconds in IBA solution resulted in rooting rate of over 70%. The longer the treatment time the worse the rooting.
This study delves into the realm of upcycling beauty design by repurposing discarded CDs, magazines, and fabrics. The study outlines a meticulous process for transforming waste into beauty designs. We created three upcycling beauty design works as part of this investigation. The first creation, called Silver Leaf, uses the silver section of CDs to craft leaves and stems. Achromatic colors are used as makeup to achieve cyber-inspired imagery. After carrying out silver-gray eye makeup, the lips were completed by affixing a CD component. The second creation is a firebird crafted by cutting or folding fashion magazines to create essential items. The colorful firebird image was completed using vivid color makeup of shades such as red and yellow. After proceeding with red eye makeup, the lips were completed by cutting and pasting magazine cutouts. The third piece is a spring flower, which involved selectively cutting lace patterns to complete a beauty design extending from head to face. The colors are spring-themed and encompass pink, yellow, and blue. Pink, blue, and green eyeshadows were applied on the lace, attached from head to face, chest, and lips. This study advocates for the prospect of upcycling beauty design using sustainable materials by repurposing waste resources. It also introduces the possibilities of creative activities in this field through upcycling. The study aims to play a role in changing the perception of environmental conservation, a concern of our times, through the use of sustainable resources.

This study was carried out to investigate the growth characteristics and propagation methods of the Korean native Amelanchier asiatica, A. arborea, and A. alnifolia as fruit trees for gardens. Due to the lack of recent research on Amelanchier spp., their superficial classification is still unclear and the names are being used interchangeably. The results are obtained as follows : A. arborea and A. alnifolia were globular type multi-stemmed shrubs. A 20-year-old tree of A. asiatica was 7.8m in height, with a 5.2m crown width, with one trunk. As for the morphological characteristics, leaves of A. asiatica were oblong, with an acuminate of, 6.1cm and 3.6cm width, but A. arborea and A. alnifolia had acute obovate leaves. The leaf size of A. alnifolia was the largest among the three species. The flower size of A. asiatica was bigger than that of A. arborea and A. alnifolia. In addition, its petals and flower clusters were also the largest among the three species. The flowering of A. asiatica initiated on April 21 and then bloomed for a duration of 24 days in Osan, while that of A. arborea and A. alnifolia initiated flowering on April 12 and then bloomed for a duration of 22 days in the same location. The fruit of A. arborea and A. alnifolia were green on May 10~12, it changed into purplish red on May 24~26, and its matured on June 1~3. The duration of fruit persistence of A. arborea and A. alnifolia were 48~50 days. On the other hand, A. asiatica showed greenish fruit on May 20, it became red on September 4, and had fallen by October 3. The fruit size was the largest at 1.03cm of height and 1.12cm of diameter in the A. arborea, followed by the big berry of A. alnifolia and the smallest fruit in the native, A. asiatica. It was difficult to root due to the hardwood cutting of A. arborea at a 40% rate of rooting. In the softwood cutting, the rooting rate of A. arborea was increased by the treatment with concentrated IBA, especially at 5,000 and 7,000ppm. The optimum date for cutting was on June 27, when the rooting rate was more than 80%. The most effective method for rooting of A. arborea was rootone or 7,000 ppm IBA treatment on June 27 softwood cuttings, which showed a rooting rate of over 80%.
The importance of leaf area as related to transpiration and photosynthesis is generally recognized. In general, a compound leaf of soybean consist of one main leaflet and two side leaflets from each node of the stem. Takahashi and Fukuyama (1919) classified soybeans into three types, namely the long leaf type, round leaf type, and intermediate type, in which the last one had round leaves at the base and long leaves in the upper part of the stem. Nagai (1925) and Takahashi (1935). dealt with the genetics of the leaf form and association with other characters. The closely relationships, the correlation coefficients from 0.64 to 0.73, were shown between the leaf area and the soybean yield in the experiments by Nagai (1942). Nagata (1950) also tested the varietal differences of the variation of leaf length and its ratio to the leaf width on the nodes of stem, and finally divided varieties into five types. Three methods of measuring area of strawberry leaves were used by Darrow (1932). The first involved determining a factor to be used with length or length ${\times}$width measurements. The second method involved placing leaves on pieces of cardboard of known area cut to the shape of the leaves. Direct use of the planimeter on intact leaves was Darrow's third method. Miller (1938) enumerated several methods to determine the leaf surface area in plants, some of which were extremely laborious and required removing leaves from plants. They included tracing outlines of leaves on paper and measuring the enclosed area with a planimeter or cutting out the traced areas and comparing the weights obtained with the weight of a known paper. Another method involved placing the form of the leaf on sensitized paper with the area being determined by measuring or weighing as above. Miller further stated that the photoelectric cell can also be utilized to estitmate leaf area. Working with field beans, Davis (1940) found that 0.004517 (length ${\times}$ width) of the center leaflet was the most nearly accurate of four methods attempted. A simple procedure to measure leaf area in corn was devised 1 y Montgomery (1911) and used by Kiesselbach (1950). The formula was length ${\times}$ width ${\times}$ 0.75. Stickler et al. (1961) have successfully used length times width ${\times}$ 0.747 to estimate area of grain sorghum leaves. Bhan and Pande(1966) has also used length ${\times}$ width ${\times}$ 0.802 to determine leaf area of rice varieties. The main objectives of the present investigation were to develop an accurate, rapid method to determine leaf area in soybean varieties and to examine certain data associated with leaf area determinations.
The optimal growth condition of in vitro stem cutting of Dendrobium nobile 'Hamana Lake Dream' ${\times}$ 'No. 55' was investigated. Among various media and their concentrations, MS media had better effect on the growth of micro stem cutting than Hyponex media in all concentration levels except stem length. The activated charcoal concentration in MS media showed different effects on number of stem and root, leaf length, and fresh weight: the most effective in the range of 0.1 to 1.0 g/L and barely effective above 2.0 g/L. Addition of agar 5 g/L, sucrose at 40 g/L, and peptone at 1 g/L to MS media increased significantly stem length, leaf width, and fresh weight, internode length and number of roots, and the number of stem and leaves. On the other hand, addition of gelite with any concentration had no effect on the growth of micro stem cutting compare to that of control. The optimal temperature for growth of micro stem cutting was $28^{\circ}C$. Under the same temperature, MS medium was better than Hyponex medium for the growth of stem. In addition, sucrose at 40 g/L was the most effective on growth at $28^{\circ}C$.
This study was carried out to investigate the combined effect of cold storage with irradiation on rooting of chrysanthemum cuttings. Each cutting was six cm in length with three real leaves. A set of Groups of the cuttings was irradiated with 0 to 70Gy of gamma-ray after four weeks of cold storage, while another groups were irradiated with the same doses and then stored at $4^\circ{C}$ for four weeks. Root and shoot growth were observed at 15 and 20 days after planting of the cuttings in a Plug tray. Accelerated root formation was observed in 30 Gy irradiated group, and root growth was also enhanced in 20 and 30 Gy irradiated groups 20 days after planting. In case of irradiation combined with pre-treatment of cold storage, survival rate of cuttings was the highest (80%) in 30 Gy irradiated group. The groups treated with irradiation first before cold storage were apparently better in root formation, among which 50 Gy irradiated group showed the highest rate of root growth.
