  • Cultivation of cauliflower mushroom (Sparassis crispa) became a good way of consumption for coniferous sawdust. However, conventional method for the cultivation demanded ready-decomposed sawdust in field more than 6 months, which resulted in the spatial and temporal problems. This study was conducted to develop an efficient cultivation method to minimize the problem with steam-treated sawdust media of Larix leptolepis, Pinus densiflora and Pinus koraiensis. By the treatment, mycelial growth was stimulated by 10% compared to that of untreated sawdust with the sawdust media of L. leptoiepis and P. koraiensis, and the mushroom productivity was improved from 12.5% (50.1 g/400 g) to 16.7% (66.7 g/400 g) with the sawdust medium of P. densiflora from first harvest in case of KFRI644. Steam treatment is thought to be a good method for cultivation of cauliflower mushroom by minimizing culturing period and increasing productivity, which is an effective way of utilization for coniferous sawdusts.

  • As the online education market expands, educational contents with various presentation methods are being developed and released. In addition, it is imperative to develop content that reflects the usability and user environment of users who use this educational content. However, for qualitative growth of contents that will support quantitative expansion of markets, existing model analysis methods are urgently needed at a time when development direction of newly developed contents is secured. In this process of content development, a typical model for setting development goals is needed, as the rules of the prototype affect the entire development process and the final development outcome. It can also provide a positive benefit that screens the issue of performance dualization between processes due to the absence of communication between a single entity or between a number of entities. In the case of AR-based educational content which is effective to secure data necessary for development by securing samples of similar categories because there are not enough ready-made samples released. Therefore, a big data statistical analysis service is needed that can easily collect data and make decisions using big data. In this paper, we would like to design analysis services that enable the selection and detection of intuitive multidimensional factors and attributes, and propose big data-based statistical analysis services that can assist cooperative activities within an organization or among many companies.

  • Objectives: Based on the results from the Korean Total Diet Study (KTDS), the sodium (Na) and potassium (K) intake of Koreans were estimated and compared with intake estimates from the Food & Nutrient Database (FNDB), as in the Korea National Health and Nutrition Examination Survey (KNHANES) to verify the validity of these estimates. Methods: One hundred and thirty-four representative foods (RFs) covering 92.5% of the total food intake of Koreans were selected, and 228 pairs of corresponding 'RF x representative cooking method' were derived by reflecting the methods used mainly in terms of frequency and quantity in their cooking. RF samples were collected from three cities with a larger population size in three regions (nine cities) nationwide, and six composite samples were made for each RF, considering its regional and/or seasonal characteristics. One thousand three hundred and sixty-eight 'RF x representative cooking method' pair samples were prepared, and the Na and K contents were assessed using inductively coupled plasma atomic emission spectrometry (ICP-MS). The Na and K intake of the Korean population was estimated by linking the content with the food intake data from the 7th KNHANES. Results: The mean Na and K intake of Koreans were 2,807.4 mg and 2,335.0 mg per person per day, respectively. A comparison with the Na and K intake from KNHANES, including only RFs of KTDS, showed comparable results with less than 5% variation. While the contribution and ranking of food items to Na intake were similar between KNHANES and KTDS, there were differences in K intake. This was attributed to the large discrepancies in the K content of rice and coffee between KTDS results and the values in the 9th Revision of the National Food Composition Table used in KNHANES. Conclusions: The Na and K intake of Koreans estimated based on the KTDS, which performed nutrient analysis on samples prepared to a 'table-ready' state using foods of the representative collection, was similar and comparable with that of KNHANES. This supports the validity and usefulness of FNDB-based nutrient intake estimation at the population level. The list of nutrients studied in KTDS is expected to be expanded, allowing for intake estimation of nutrients with currently insufficient or absent information in the FNDBs in use.

  • Lactic acid bacteria(LAB) were isolated from fermenting Kimchi and were cultivated in filter-sterilized Chinese cabbage juice individually or in combination. LAB isolated were Lactobacillus leichimannii, Lac. fermentum, in addition to the already known Leuconostoc mesenteroides, Lac. plantarum, lac. brevis and pediococcus pentosaceus. Lac. leichimannii, Lac. fermentum and Lac. sake, the early lactobacilli, were high in number exceeding $10^4cells/ml$ at 0 time and multiplied up to $10^9cells/ml$ altogether at the 3rd day of kimchi fermentation. When the representative LAB were cultivated singly in Chinese cabbage juice with or without 3.0% NaCl, one strain of Leu. mesenteroides and La. leichmannii were not different in acid producing ability while the other strain of Leu. mesenteroides and Lac. fermentum Lac. plantarum, produced less acid when NaCl was present. When the bacteria in combination were cultivated in Chinese cabbage juice with 3.0% NaCl, the presence of Leu. mesenteroides was essential to eliminate the lag phase in acid production with higher amounts of acid produced than without. The total number of lactobacilli in the mixture of kimchi ingredients was about $2.9{\times}10^4 cells/ml$ while the number of Lac. plantarum was 7.3 cells/ml. The number of Lac. plantarum in individual ingredients were normally in the range between $0.0{\sim}240cells/g$ except garlic sold in ready-to-use form with $9.0{\times}10^3 cells/g$.

  • Titanium or titanium alloy is a widely used implant material according to its certified biocompatibility, sufficient strength and ready availability. The purpose of this study was to evaluate the relative biocompatibility of titanium and titanium alloy specimens (Ti-29Nb-13Ta, TiNb and Ti-6Al-4V, Ti64) using in vivo and in vitro methods. For in vivo experiment, the specimens were implanted in the abdominal subcutaneous region of female mice for 2 and 4 weeks. The reaction of connective tissue to specimens was evaluated histologically. The specimens were encapsulated by fibrous connective tissue consisting of fibroblast, fibrocyte and other cells including neutrophil, macrophage, giant multinucleated cell and unidentified cells. Some newly formed blood vessels were located in the fibrous capsule surrounding the implant. Cell types and the thickness of fibrous capsules were examined quantitatively. Most of cell types located in the fibrous capsule were fibroblasts and fibrocytes. The average thickness of fibrous capsules for the TiNb specimens was much thinner than that of the titanium alloy, Ti64. The thickness of the fibrous capsule around all titanium specimens decreased at 4 weeks compared to 2 weeks post-implantation. The biocompatibility of titanium and titanium alloy specimens were also investigated in in vitro method using alkaline phosphatase from MG-63 cells. Alkaline phosphatase activity of the TiNb specimen showed higher activity than the titanium alloy, Ti64. In conclusion, the TiNb alloy with thin capsule thickness in vivo and high alkaline phosphatase activity in vitro will be of considerable use in biomedical applications.

  • This study was conducted to investigate the perception of the management of food service in schools. The subjects consisted of 271 school dietitians in the Daegu and Gyeongbuk areas. The questionnaire included the food temperature management and the frequency of the food quality confirmation. The sanitation performance of the delivery workers was evaluated with a 5-point Likert scale. The food items for which the proper temperatures while they were being received were difficult to maintain were as follows: ready-to-use vegetables, 49.8%; frozen foods, 30.3%; and fish paste, 27.7%. The frequencies of the food quality confirmation whenever the foods were received were as follows: for beef, 87.5%; pork, 84.5%; chicken, 84.1%; eggs, 73.4%; seafood, 59.4%; and processed foods, 52.8%. The total mean score of the dietitian-perceived sanitation management performance of the delivery workers was 3.86/5.00. The school dietitians said the percentage of the mixed delivery of food items in vans was 80.4%. The percentage of the dietitians who thought this mixed delivery influenced food sanitation and quality was 92.3%. Therefore, safe foods should be supplied to schools with a thorough inspection process and hygiene education, and professional research is required on the appropriate inspection process.
