The main purpose of this study was to verify the shore margin protection effect of the root system of Salix gracilistyla Miq. developed from direct sticking cuttings on wetland, through the measurement of root growth and comparison of soil slaking rate depending on the planting method applied to shore-marginal slope. Comparison of growth rate and soil dispersion rate was made between five planted slope and one naked slope. The planting methods applied to the planted slope were (a) horizontally layed burying of stick(45cm) bundle (b) horizontally layed covering the slope with sticks (c) horizontally fencing with normal cuttings(20cm) (d) elected sticking of normal cutting at equal distances (e) random scattering short cuttings(3-4cm). As results, the most effective planting method was horizontally layed burying, and in order to increase its efficiency scattering the live stem chips in 2-3cm on the slope is recommended. The growth of root was negatively regressive to the distance from water floor.

Purpose: An autonomous robot was developed for harvesting strawberries cultivated in bench-type systems. Methods: The harvest robot consisted of four main components: an autonomous vehicle, a manipulator with four degrees of freedom (DOF), an end effector with two DOFs, and a color computer vision system. Strawberry detection was performed based on 3D image and distance information obtained from a stereo CCD color camera and a laser device, respectively. Results: In this work, a Cartesian type manipulator system was designed, including an intermediate revolute axis and a double driven arm-based joint axis, so that it could generate collision-free motions during harvesting. A DC servomotor-driven end-effector, consisting of a gripper and a cutter, was designed for gripping and cutting the strawberry stem without damaging the strawberry itself. Real-time position tracking algorithms were developed to detect, recognize, trace, and approach strawberries under natural light conditions. Conclusion: The developed robot system could harvest a strawberry within 7 seconds without damage.

The development of medicinal plants for cut plants and landscape plants were conducted through the literiture survey. The results were as follows: We selected 38 species of medicinal plants including 7 medicinal woody plants for cut plant and landscape plants from 450 medicinal plants. There were 8 species of Compositae, 4 species Ranunculaceae, 3 species Rosaceae and Umbelliferae, 2 species Polygonaceae and Campanulaceae respectively. The anthesis of Cornus officinalis, Magnolia denudata, Forsythia koreana of medicinal woody plants flowering before leaf spreading come to early than the anthesis of other medicinal plants. There were 4 species(11%) over 10cm of the flower diameter, 6 species(16%) over 5cm below 10cm, 19 species(50%) over 1cm below 5cm and 9 species(24%) 1cm below. In terms of flower color, 11 species(29%) were white, 9 species(24%) yellow, 6 pecies(16%) red, 5 species(13%) violet and 3 species(8%) were blue aided violet. In terms of the flowering by month, 12 species(32%) on July, 9 species(24%) on May, 6 species(16%) on June and August respectively, and 3 species(8%) on March. The most medicinal plants were propagated by division and seeding easily, but woody medicinal plants of 7 species of this study were propagated by cutting and grafting easily. The percentage of usage of parts of medicinal plants including woody medicinal plants was that roots were 20 species(53%), flowers 6 species(16%), fruits and all part of medicinal plants were 4 species(11%), and seeds and stem including leaves 2 species(5%) respectively.

Since the sesame pod gets open gradually from the lower to upper parts of the stem due to its different maturity during cutting and binding of sesame, at the conventional work for shattering, the procedures of drying and shattering are repeated two or three times. Therefore, in this study, a drying stand with transparent plastic cover was developed to complete the drying and shattering at the same time. Owing to the developed drying stand, simple drying work, the area for drying was reduced prevention of sesame seeds from loss and rain are available. The performance of developed drying stand was evaluated. Before the drying stand was developed, the conventional method and shattering machine for shattering sesame required at least three times of operation for complete shattering. But After drying stand was developed, the complete shattering works was possible with only one time shattering operation. Finally, the developed drying stand could prevent approximately 5% of the total sesame seed production from loss during drying and shattering works.

This study aims to investigate the food preservation methods adopted by the Joseon Dynasty, which existed before the 17^th century. A total of 232 food preservation methods were discovered in 25 books, and could be classified by their targeted food types: vegetables (84), sea foods (60), meats (41), fruits (37), and others (10). Depending on the preservation method applied, they are classified as food drying, soaking, mud cellar preservation, and other preservation. Food drying is further classified into 8 sub-types: drying, sun-drying, shadow-drying, wind-drying, dry heat, combined drying, smoking, and others. Soaking could be sub-divided into using salt, ash, dry sand, bran, fermented paste, wet distillers grains, oil, and others. Mud cellar preservation is sub-classified into installing shelf inside the mud cellar, making the mud cellar for food preservation, and making hole or underground tunnel for food preservation. Other food preservation methods include minimizing moisture loss by applying beeswax on a section of the vegetable stem, and cutting the vegetables or fruits with their branches and leaves for food preservation.

Soilborne diseases pose a serious problem for mulberry cultivation during nursery plantation and established gardens, which cause severe loss in revenue generation of mulberry growers as compared to foliar diseases. Various soilborne diseases affect mulberry. Among them, root knot and root rot affect the established plantation resulting in severe loss in leaf yield apart from deterioration in leaf quality, which is a pre-requisite in successful sericulture to get the good quality of cocoons. Besides, stem-canker, cutting rot, collar rot and die-back, affect the initial establishment and survivability of mulberry plantation in nursery. The problem is difficult to handle, due to the complex nature of the diseases and also involvement of various biotic and abiotic factors. This is compounded by the occurrence of disease complex (especially nematode ＋ soilborne pathogenic microbes) in established mulberry gardens, which facilitates quick spread of the disease and enhance the plant mortality, resulting substantial loss in leaf yield. Therefore, prevention and timely control measures need to be taken up to protect the mulberry plants from different soilborne plant pathogens. In this review article, symptomatology, epidemiology, disease cycle and control measures of soilborne diseases of mulberry are discussed.

A disease survey on the carnation (Dianthus caryophyllus L.) wilt was conducted during the high temperature period (June through August) and the low temperature period (February through May) in 58 greenhouses of its major cultivation areas, including Pusan, Kimhae, and Changwon in Korea from 1998 to 1999. The disease incidence was averaged 5.4% and 11.9% in the low and high temperature periods, respectively. Severe damage was found in summer with high incidences of around 50% in some greenhouses. Close examination of the symptoms and isolation of the causal agent revealed that there was a new disease different from Fusarium wilt caused by Fusarium oxysporum f. sp. dianthi, which was determined as the stub dieback caused by F. was cetermined as the stub dieback caused by F. graminearum (teleomorph : Gibberella zeae). The stub dieback symptoms involved brown rot of stem that started usually from the portion of cutting without discoloration of inner vascular tissues. Seven out of 38 isolates from the wilted plants were identified as F. graminearum, while the others as F. oxysporum f. sp. dianthi. Mycological characteristics of the stub dieback pathogen including colony color, absence of microconidia, and the shape of macroconidia, were consistent with F. graminearum previously described. This is the first report of the carnation stub dieback in Korea.
