  • This study attempts to determine the strategy to improve the quality of staff supervision by exploring the experiences of the staff supervision in community welfare centers. For this purpose, multiple case study was performed by conducting in-depth interviews with 10 supervisors for the analysis data and analyzing the resulting themes. The key subjects from their experience were 'Supervisors recognize and prepare the supervision as Challenge and Aspiration', 'Supervision leaves only chaos and frustration', and 'Inspiration from the supervisor and infinite effort result in fruit'. Based on these results, this study suggests the following practical suggestions for the educational, administrative and supportive functions of Supervision. First, educational functions should be proposed as an extension of supervisor's education opportunities and manuals related to educational growth of supervision. Second, the administrative function should be changed to evaluate social welfare institution's evaluation framework so as to evaluate the supervision internal regulation and supervision according to it and various supervision models should be developed. Third, supportive supervision function that can be encouraged for supervisees should be enhanced. This study was meaningful because it presents specific suggestions for supervisors and supervisee's relation and situation in the community welfare center through the qualitative research method.

  • Many farmers have been seeking alternatives to chemical fertilizer for successful organic fruit production. This experiment was carried out to investigate the replaceability of chemical fertilizer by cover crop and slurry composting biofiltration (SCB) liquid manure (LM) application in pear orchard. Three treatments were contained in this experiment; cover crop only and cover crop + LM treatment, and control (chemical fertilizer application). Dry weight and mineral contents of gramineous cover crops were significantly increased in LM-combined treatments than that of leguminous species. Bulk density of soil was decreased in rye + LM and hairy vetch + LM treatments, compared with each cover crop treatment. Soil pH was lowest in fertilizer treatment and soil nitrate content became similar between treatments after rainy season. Available soil phosphate was lower in cover crop and cover crop + LM treatmemts than control, but exchangeable Mg was higher. The mineral content and net assimilation rate of leaves showed no difference between the treatments. As a result, it is suggested that the application of SCB liquid manure in pear orchard managed by cover crops is desirable to maintain the productivity by improving soil physical properties and potential nutrient recovery.

  • This study was conducted to determine the germination characteristics, oil contents and fatty acid compositions of the different safflower accessions. The safflower accessions had nearly the same germination period of about 12-13 days and the germination rate was more than 87.5%. Plant height grew until 84 days after seeding. The number of leaves did not increase after 70 days from seeding. The accessions had a difference of six loaves from 17 to 23 loaves. Flowering time had a difference of 11 days from 79 days after planting to 90 days after planting. The Jangsung accession had the shortest flowering time of 79 days after planting. In the characteristics of bearing fruit, the number of branches including main stem are from 4.7 to 8.8. The number of head flowers had nearly the same number of branches which were 4.8-8.9, numbers of seed per head flower were 29.3-49.1 and the weight of 100 seeds were 2.9-3.9 g. The crude fat content was 21.8-33.9% and fatty acid content was 66.6-77.6% containing mostly linolenic acid. Oeic acid content was 9.2-16.5% and it contained palmitic acid, stearic acid, venin acid, arachidonic acid etc. Results of this study, the accession Jangsung, which had the shortest flowering time and had the most crude fat content, was observed to be the best accession for the breeding of safflower.

  • In analysis of inorganic components of Miscanthus sinensis Andersson var. sinensist, Phosphate increased with the progress of growing stage. in other way potassium, calcium and magnesium was inclined to decrease. The total nitrogen content in the Miscanthus sinensis Andersson var. sinensist was increased until second age cultivated stage, but in its third year, it was decreased apparently. In other way the total carbon content of Miscanthus sinensis was not changed until second year cultivation. But rapid increasing was happen in its third year cultivation stage. 3 year cultivated Miscanthus sinensis Andersson var. sinensist which has a plentiful carbon source can be used as a good culture media source for the formation of mushroom's fruit body. When rice bran added at the amount of 20% to the keep in 65% moisture Miscanthus sinensis Andersson var. sinensist, the fermentation of culture material was well done and the temperature of $50{\sim}55^{\circ}C$ fittest for thermophilic microorganism growth was maintained for 5 days from 5 days after treatment. Rice bran 20% added to the Miscanthus sinensis Andersson var. sinensist was the fittest fermentation culture media for the Pleurotus ostreatus vinyl-bag type cultivation. When Pleurotus ostreatus was cultivated in this culture media, the yield was increased by 60% than whole Miscanthus sinensis Andersson var. sinensist containing culture media. The fermentation Miscanthus sinensis Andersson var. sinensist culture media could be substituted by 20% the sawdust in existing culture media(sawdust 50%+cottonseed bark 30%+cottonseed meal 20%).

  • An outbreak of Ricania sp. occurred in the Kurye, Jeonnam area in 2011. This outbreak damaged many kinds of fruit trees such as Cornus, Persimmon and Chestnut. This experiment was conducted to survey the occurrence ecology of Ricania sp. such as host plants, oviposition characters, morphological characters and life cycle, as well as to select environmental friendly control agents. Ricaina sp. host plants included 51 species such as 32 xylophytes, and 19 herbaceous plants. Ricaina sp. preferred Cornus officinalis, Diospyros kaki, Castanea crenata, Eucommia ulmoides, Styrax japonicus for oviposition. Adults laid eggs on new inner twigs with 28.8 eggs per egg-mass. Egg size was 1.24 mm(length), 0.55 mm(width) in an oval shape. Nymphs molted four times. Every nymph stage had an x shape of yellow or white beeswax around the anus. Overwintered eggs of Ricania sp. hatched from the mid May to early June. Nymphal periods were from mid May to mid August and adults appeared from mid July but spawning began in mid August. Ricania sp. damaged new twigs by oviposition and retarded growth by sucking nutrients and producing a sooty mold. Sophora and natural plant extracts were effective environmentally friendly agricultural materials used to control the nymph and adult Ricania sp. Mortality was > 80%.

  • Fermented milk was prepared from milk or mixture of milk and apple juice/grape juice, and it was freeze dried. pH change and growth of Lactobacillus acidophilus (KCTC 2182) during freeze drying were studied. The effects of freeze drying on sensory evaluation and volatile aroma compounds in freeze dried sample or reconstituted sample were also studied. Freezing and freeze drying did not affect pH of fermented milk. Number of viable cells of L. acidophilus was markedly reduced during freezing or freeze drying. When number of viable cells in original fermented milk was considered as 100%, survival ratio of viable cells after freezing was $64.5{\sim}85.2%$ and that after freeze drying was $10.0{\sim}21.1%$. When sensory properties of original fermented milk prepared from juice-milk (ratio 15:35) were compared with those of freeze dried/reconstituted sample, sensory properties of original sample were better than those of freeze dried/reconstituted sample. Ethanol, diacetyl, butanol and acetoin were detected in all of original samples and freeze dried/reconstituted samples while acetone was detected in samples containing high amount of grape juice. Volatile aroma compounds in original fermented milk were reduced during freeze drying. L. acidophilus produced ethanol, diacetyl and acetoin during fermentation.

  • A new blackish-brown variety of Flammulina velutipes, 'Yeoreumhyang2ho,' which was bred by crossing two monokaryons isolated from the 'Heukhyang' and 'Garlmoe' varieties, showed adaptability to high temperature. During bottle cultivation, the temperature was maintained at $16^{\circ}C$ and the variety displayed good productivity compared to the control ('Heukhyang'), without necessitating low temperature ($4^{\circ}C$) treatment. The period necessary for mycelial and fruit body growth, and primordia formation was 24 days, 8 days, and 8 days, respectively. The total cultivation period was 40 days, which was 3 days shorter than that of the control. Particularly, primordia formation took 2 days less than the control and showed initial uniformity. The yield of 'Yeoreumhyang2ho' was 154 g per 850 ml bottle, which was 8% higher than the control yield. The ${\beta}-glucan$ content was 67.9 g per 100 g dry weight, which is approximately 1.1-2.2 times the amount of ${\beta}-glucan$ in control, the golden and white mushrooms that are available in the market.

  • The production and consumption of fresh mushrooms has been increasing worldwide because of the health benefits of the dietary fiber and antioxidant components. Using 142 valid patents from five countries, trends in postharvest technology patents were analyzed and categorized into packaging and storage. The patent portfolio index showed that the number of patents for postharvest storage technology is growing, with the number of both approved patents and applications increasing from the third to the fourth time period, albeit the overall growth pattern suggests that this is a recovery stage. Notably, Korea showed an increasing trend in the number of patent applications related to postharvest technologies, although the number of patent applications was smaller than that of China. Our study describes trends in technical patents that support the performance of new postharvest projects of fresh mushrooms.
