The purpose of this study is to analyze the types of Hibiscus patterns expressed on Aloha shirts. This study analyzed real data collected from man's aloha shirts displayed at the International Market Place in Waikiki of Hawaii during January 21-27, 2007. 35 pieces of Aloha shirts with Hibiscus Patterns were was analyzed. The total of each analysis means all number of patterns sampled or appeared to analyze the types of patterns. The motif of Hibiscus was sampled a total of 42 units for some shirts having several motifs. Its motif was divided into two groups, 20 units(47.62%) of natural type and 22 units(52.38%) of stylized type, according to modeling. Two types were much the same percentage. Hibiscus patterns were classified into three groups, isolated, band and arabesque type, by formation type. The isolated type was appeared most frequently. The layout of Hibiscus pattern was classified into three groups, engineered print, all over print and border print. All over print was appeared most frequently. The data of this study will be provided as a resource to promote using and developing of the pattern of Korean rose of Sharon.

This study identifies the basic personality types of subjects who use the healing garden and investigates their plants-preference. The purpose of the study is to provide a basic information about planting plan, considered as a main parts of healing garden. Survey results are stated as follows: First, the order of preference of instinct type tree is Prunus yedoensis, zelkova serrata, Phyllostachys Bambusoides. On the other hands, the order of preference of feeling and thinking type is Prunus yedoensis, zelkova serrata, Metasequoia glyptostroboides. Second, the order of preference of instinct type of flowers is Rosa hybrida, Hibiscus syriacus, Forsythia koreana. However, the preference of emotional type is the order of Rosa hybrida, cosmos bipinnatus, Helianthus annuus and the preference of accident type is the order of Rosa hybrida, Hibiscus syriacus, Helianthus annuus. Third, for the color preferences, instinct type prefer yellow color, feeling type and thinking type prefer red color. Lastly, when people view plants, most personality types are interested in flower firstly, and secondly type of tree and scent. In other words, we can assume that people are interested in the flowers, most noticeable in plants. This study will enhance the effectiveness of the healing garden by providing relevant information regarding healing garden planting plan. Future research should consider to widen the range of target of investigation in order to perform additional comparison analysis.

Kaempferitrin, isolated from Kenaf (Hibiscus cannabinus), was examined to evaluate its modulatory effects on antigen-presenting cell functions of macrophages/monocytes such as phagocytosis of foreign materials, up-regulation of costimulatory molecules (CD40, CD80 and CD86), adhesion molecule activation, and antigen processing and presentation. Kaempferitrin strongly blocked up-regulation of CD40, CD80 and CD86, but not pattern recognition receptor (PRR) (e.g., TLR2). It also suppressed functional activation of CD29 (${\beta}1$-integrins), as assessed by cell-cell adhesion assay, required for T cell-antigen-presenting cell (APC) interaction. Furthermore, this compound did not block a simple activation of CD29, as assessed by cell-fibronectin adhesion assay. However, the compound did not diminish phagocytic uptake, an initial step for antigen processing, and ROS generation in RAW264.7 cells. In particular, to understand molecular mechanism of kaempferitrin-mediated inhibition, the regulatory role of LPS-induced signaling events was examined using immunoblotting analysis. Interestingly, this compound dose dependently suppressed the phosphorylation of $I{\kappa}B{\alpha}$, Src, Akt and Syk, demonstrating that it can negatively modulate the activation of these signaling enzymes. Therefore, our data suggested that kaempferitrin may be involved in regulating APC function-relevant immune responses of macrophages and monocytes by regulating intracellular signaling.

Background and objective: This study analyzed the growth characteristics, in relation to the soil moisture content, of trees planted in an environment with limited soil depth to provide the baseline data for effective irrigation management. Methods: The experimental treatment was divided into soil moisture contents (SMC) of 20%, 15%, 10%, 5%, and 1%, and the respective watering times were set accordingly. As for plant materials, Nandina domestica, Euonymus alatus, Thuja occidentalis, Hibiscus syriacus, Pinus densiflora, and Pyracantha angustifolia, were chosen for this study, because they are highly likely to be used in urban street environments. Results: The minimum irrigation point suitable for each species was determined by considering various aspects of visual quality and water efficiency in terms of plant growth, including characteristics such as height, root diameter, rootlet development, and weight. Our results indicate that N. domestica should be watered so that the moisture content of the soil is of at least 5%, based on the balance between the stem and roots, as well as on visual quality. E. alatus and P. angustifolia are suitable for watering that results in at least 10% SMC, considering the height, root growth, weight, and visual quality of plants. As for T. occidentalis, it showcases moderate growth with a soil moisture content of at least 5%. Finally, the minimum irrigation time required to obtain 15% SMC is appropriate, in terms of plant growth, fresh weight, and visual quality, for H. syriacus and P. densiflora. Conclusion: This study suggested a basic irrigation guideline for container gardens where trees planted in environments with limited soil depth can be managed so that they are visually appropriate and in good condition of growth.

This study was conducted from April 13 to October 8, 2001 in Jeju to determine the influence of cutting height (2, 4, 6, 8 and 10 cm from the soil surface) on growth, forage yield and chemical composition of kenaf (Hibiscus cannabinus L.). As cutting height was increased from 2 to 10 cm, plant height averaged across two cuttings increased from 157.7 to 184.7 cm. This pattern held fir the number of leaves and branches per plant, stem diameter and plant weight per plant. As cutting height increased from 2 to 10 cm, fresh forage, dry matter, crude protein and TDN yields increased from 85.5 to 113.7MT/ha, from 11.97 to 15.63 MT/ha, from 1.63 to 2.72, and from 4.95 to 7.54 MT/ha, respectively. As cutting height was increased from 2 cm to 10 cm, crude protein, ether extract, nitrogen free extract, and TDN contents increased from 14.2 to 17.6%, 2.9 to 3.9%, 24.2 to 25.8% and 43.1 to 48.5%, respectively, while crude fiber and crude ash contents decreased from 35.5 to 30.4 % and 9.9 to 8.1 %, respectively.

Evegradies 71' kenaf (Hibiscus cannabinus L.) was grown at 160,000 plants per ha in a volcanic ash soil in Jeju island to determine the optimum frequency of split N application fer forage production. Nitrogen fertilizer was applied with 240 kg/ha, and frequencies of the split N applications were 1, 2, 3, 4 and 5 times. Plant height averaged across two harvests increased from 187 to 201cm as N was split-applied from one to three applications and then decreased to 201cm in five applications. This pattern held for the number of branches and leaves per plant stem diameter and weight of plant per plant. Fresh forage yield increased from 91.8 to 114.2 MT/ha. dry matter yield from 12.70 to 16.6 MT/ha, crude protein yield from 1.75 to 2.48MT/ha, and total digestible nutrients (TDN) yield from 5.39 to 7.63 MT/ha as N was split-applied from one to four applications, and then decreased to 106.6, 15.0, 2.32, and 7.22 MT/ha in five applications, respectively As N was split-applied from one to five applications, crude protein content increased from 13.8 to 15.4%. ether extract content from 4.1 to 5.9%, and TDN content from 42.4 to 48.1%. but crude fiber decreased from 38.2 to 37.1% and crude ash content from 11.5 to 8.6%. Nitrogen free extract content was about 19.0% regardless of cutting height.

Present system of seed potato production in Korea has several weak points and consequently has difficulties in covering annual shortage of 60,000 tons of seed potatoes. The author has an opinion that this so called 'High land system' of seed potato production adopted by the Government should be replaced by the 'Coastal area system' which is proposed by the author and has many advantages over present 'High land system'(2). In coastal areas where enormous acreage of rice paddies are spread, mostly around the villages. the primary host plants of the vectors are found. Therefore, the only source of aphid vectors are limited to the villages. The farmer's houses scattered more sparsely also have minor importance. In the previous paper(2), the author reported that the aphid vector populations were lower in the coastalareas than at Taegwanryong where the Alpine Experiment Station for the production. of seed potatoes is located. However, the number to vectors at Okku showed rather high density, where the trap was placed at the distance of 200 m from a village where peach and Hibiscus trees, the primary hosts of Myzus pesrsicae and Aphis gossypii were grown. To clarify the flight distance from the source of the aphid vectors, a trial was carried out in the Kwanghwal area, Kimje-gun, Cholla-pukto. on the western coast. 13 traps were placed at four directions and the distances between the traps were 250 m. (Fig. I) The traps 'Were operated from June 21 to October 31. The results are shown in Table 1. A total of some 70 species of aphids were found, including 5 speceis of potato virus vectors. The vectors are as follows: I. Myzus persicae (Sulzer) 2. Aphis gossypii Glover 3. Aulacorthum solani (Kaltenbach) 4. Lipaphis erysimi (Kaltenbach) 5. Macrosiphoniella sanborni (Gillette) Out of a total of 12,797 aphids, 5,187$(48\%)$ vectors were found. The trap catches at the 13 locations are shown in Fig. 2 and the numbers of the vectors at each location for each vector, except Macro-siphoniella sanborni. of which only a single individual was caught, are shown in Fig. 3-6. Number of vectors at C (3,279) (Centre of the village) is considerably higher than that at Suwon (763); however, EI. SI. WI and NI. where the distanecs from Care 250 m, showed lower numbers of vectors than that at Taegwanryong (347). The number of vectors at NI was rather than at the other 3 locations at the distance of 250m from the village. This was because C was in the southern part of the village. Consequently NI was much closer to the village than the other 3 locations of the same distance from C. Numbers of catches of the most important vector. Myzus persicae, are shown in Fig.3. The distribution pattern is typical except $S-2\;and\;W_3$, where several farmer's houses were found. If only the rice paddies were found in these locations. the numbers of the vectors would be small as the distances increase. Numbers of catches of the other 3 vectors are shown in Fig. 4-6. From these results. the author has drawn the following conclusions: 1. The aphid vector sources at the rice paddy belt in the western coast are the villages. 2. The vector densities at the locations where the distances are 250 m from the centre of the village are lower than that at Taegwanryong. 3. The vector densities become gradually lower as the distances from the centre of village increase. However. depending on the host plant situation at each location, the vector densities are variable. These minor sources of aphid vectors may be eliminated so that seed potatoes can be grown. 4. Thus. under the direction of specialists, fields suitable for seed potato production can be found in the coastal areas.
