Recently, as the internet usage is increasing, accordingly generated text data is also increasing. Because this text data on the internet includes users’ comments, the text data on the Internet can help you get users’ opinion more efficiently and effectively. The topic of text mining has been actively studied recently, but it primarily focuses on either the content analysis or various improving techniques mostly for the performance of target mining algorithms. The objective of this study is to propose a novel method of analyzing the user’s requirements by utilizing the text-mining technique. To complement the existing survey techniques, this study seeks to present priorities together with efficient extraction of customer requirements from the text data. This study seeks to identify users’ requirements, derive the priorities of requirements, and identify the detailed causes of high-priority requirements. The implications of this study are as follows. First, this study tried to overcome the limitations of traditional investigations such as surveys and VOCs through text mining of online text data. Second, decision makers can derive users’ requirements and prioritize without having to analyze numerous text data manually. Third, user priorities can be derived on a quantitative basis.

In order to identify key nations and bird species of conservation concern we described multinational collaborations as defined using network analysis linked by birds that are found in all nations in the network. We used network analysis to assess the patterns in bird occurrence for 10,422 bird inventories from 244 countries and territories. Nations that are important in multinational collaborations for bird conservation were assessed using the centrality measures, closeness and betweenness centrality. Countries important for the multinational collaboration of bird conservation were examined based on their centrality measures, which included closeness and betweenness centralities. Comparatively, the co-occurrence network was divided into four groups that reveal different biogeographical structures. A group with higher closeness centrality included countries in southern Africa and had the potential to affect species in many other countries. Birds in countries in Asia, Australia and the South Pacific that are important to the cohesiveness of the global network had a higher score of betweenness centrality. Countries that had higher numbers of bird species and more extensively distributed bird species had higher centrality scores; in these countries, birds may act as excellent indicators of trends in the co-occurrence bird network. For effective bird conservation in the world, much stronger coordination among countries is required. Bird co-occurrence patterns can provide a suitable and powerful framework for understanding the complexity of co-occurrence patterns and consequences for multinational collaborations on bird conservation.

For the development of processed food for hypoglcemia, it is important to construct model system to confirm factors that reduce the glycemic index in real food. This study was to investigate the relationship between the gel model system and real food the high amylose type of segoami using response surface methodology. The independent variables were concentration (X1; 10, 15, 20, 25, and 30%) and steaming time (X2; 30, 35, 40, 45, and 50 min). The predicted glycemic index (Y1) was analyzed as a dependent variable. The regression of pGI was 0.7343, indicating that the model fits the data well in the prediction test. The predict glycemic index of the gel was in the range of 71.38 ~ 83.78, depending on the gel preparation conditions and predicted optimum condition was 23.7% gel concentration and 43.8 minutes of gelatinization. The predict glycemic index of rice gel were decreased with an increase of gel concentration, rather than the steaming time. In order to confirm the effect on in vitro digestibility in real food, the real food (Garraedduk) was prepared by applying the optimal conditions. As a result, there was no significant difference between the predicted value (77.1) and the experiment value (76.6). This result showed that the in vitro digestibility in real food can be predicted by applying the gel model system.

Euzophera batangensis (Lepidotera: Pyralidae) is seriously damaging trunks or branches of persimmon tree (Diospyros sp.). We tested the attractiveness of (Z)-9-tetradecen-1-ol (Z9-14OH) and (Z9,E12)-tetradeca- 9,12-dien-1-ol (Z9,E12-14OH) with single or blended baits at southern parts of Korea in 2014 and 2015. The monoene was not attractive at all at three places during the two years. In 2014, diene was equally or more attractive than the mixture in Jinju and Suncheon, respectively. In 2015 too, the attractiveness of diene and mixture was not different in Jinju and Munsan. Monitoring of the seasonal occurrence of E. batangesis with the sex pheromone components revealed that it occurred three times a year; the first occurrence from early April to mid May, the second from early Jun to mid July, and the third from late August to late September.

Non-target predatory insects can be indirectly exposed to aerial pesticide spraying and fogging to control Monochmus beetles that transmit pine wood nematode, Bursaphelenchus xylophilus. We evaluated potential lethal or sublethal effects of thiacloprid on survival and behavior of a carpenter ant species, Camponotus japonicus Mayr. Field-collected ant colonies were directly exposed to several food items, such as thiacloprid-addicted Monochmus beetles, 10% sugar watered cotton balls contaminated by thiacloprid concentrations, and 10% sugar water. Dead beetle bodies caused no apparent adverse effect through dietary exposure in general, although a few ants were died with paralysis at colony level experiment. At individual level, most ant workers were died within 10 days compared to control group. In contrast, dietary exposure of ants to thiacloprid concentrations showed significant lethal effect with paralysis and impaired walking, especially at 10 and 50 mg/L thiacloprid concentrations. Some intoxicated ants recovered within a few days in 10 and 50 mg/L thiacloprid concentrations, but intoxicated ants were generally shown to be less responsible to enemy ants with low aggressive behavior. Implications for predicting hazards of thiacloprid to beneficial arthropods in pine forests are discussed.

This study purposed to provide a scientific base for understanding the effect of therapeutic intervention using motivation on chronic stroke patients’balance and determining whether it is applicable as a new therapeutic intervention. For this study, we sampled 38 chronic stroke patients, and divided them randomly into a motivation training group(n=20) and a control group(n=18). To the control group was applied neurological physiotherapy 5 times a week, and 30 minutes each time, and to the motivation training group was applied neurological physiotherapy and then, additionally, a Nintendo Wii-Fit program 3 times a week, and 30 minutes each time. Before and after the experiment, the subjects’dynamic balance was measured with functional reach test(FRT), timed up & go test(TUG), and 10m gait test, and their static balance was measured with the Romberger Test. When dynamic balance ability was compared between before and after the experiment and between the motivation training group and the control group, significant difference was observed in the results of FRT, TUG, and 10m walking test between before and after the intervention(p<.05). As to static balance, in addition, body balance movement distance was not significantly different. Therapeutic intervention using dynamic motivation was found to be more effective than the control group in improving dynamic balance.

Agaricus bisporus grows on a substrate known as compost, which is a product of aerobic fermentation by various microorganisms. These organisms convert and degrade the straw and form lignin humus complex which is utilized later on by the population of organisms. Theses microflora play a key role in the process of composting and can be regarded as the active agents in the preparation of nutrient medium as many of them may ultimately contribute themselves to the nutrition of A. bisporus. The diversity of microflora according to growing farmhouse and fruiting body of Agaricus bisporus were investigated. The aerobic bacteria and Bacillus as longer of turning stage of compost pile were increased. And, thermophilic actinomycetes and fluorescent Pseudomonas sp. showed high density after the pasteurization stage. But Tricoderma sp. was decreased toward the end of turning stage of compost pile. Ten mushroom farms was selected to research of microflora of fruiting body of button mushroom. The microflora showed significant difference according to mushroom farms. The bacteria density was 0.4~41.6×105 cfu/ml and the fungus was 1.3~3.9×103 cfu/ml. But The microorganism density was not significant change for the storage periods. These isolates were classified into Chryseobacterium indologenes(6 strains), Pseudomonas agarici(5 strains), Sphingobacterium multivorum(2 strains), Flavobacterium anhuiense(2 strains), Microbacterium sp.(10 strains), Pseudomonas sp.(13 strains) on the basis of 16 rDNA analysis. The most dominants of these species were Chryseobacterium indologenes and Pseudomonas agarici.
