  • To investigate the effect of cereal powders on the quality and storage characteristics of sausage, Aw, pH, microbial count, TBA value, VBN value, textual and sensory characteristics were examined. Water activity tended to decrease as storage time prolonged and all the samples showed higher Aw's than that of the control. During the storage period, pH values of all the samples decreased. L, a and b values had a tendency to decrease during the storage period. During the four weeks storage at 4$^{\circ}C$, TBA and VBN values of all the sample showed increasing tendency and were lower than those of the control. Total plate counts of bacteria, the number of lactic acid bacteria and coliform bacteria counts increased as the storage time prolonged. Texture characteristics of all samples increased up to 1 week storage and decreased subsequently. The sensory scores of all the samples decreased as the storage time prolonged.

  • Fungal contamination of built-in furniture is a frequent problem in Korea when new apartment is built. However, domestic information on the contaminating fungi is very limited. This study was conducted to isolate, identify and characterize the fungi of the problem in one of the apartment houses where the fungi were claimed in the built-in furniture before the house owner moves in. Fungi present in the furniture installed in a main room, dress room, and kitchen side were visually and microscopically confirmed and purely isolated on PDA. The isolated fungi were identified by analyzing the morphological characteristics and nucleotide sequence of the ITS, calmodulin gene, and TEF-1α gene. Aspergillus creber, A. niger, A. pseudoglacus, A. ruber, Cladosporium perangustum and Penicillium commune were identified. Four out of the six fungal species were positive for at least one enzyme in six kinds of extracellular enzyme assays. When these four species (A. creber, A. niger, C. perangustum and P. commune) were inoculated onto four kinds of wood chips of furniture materials, they were able to colonize all of the wood chips. Their settlement was better at 95% humidity condition than at 30% humidity condition. Among the four species, C. perangustum caused the darkest discoloration and secreted the most number of extracellular enzymes. The four species were re-isolated from the colonized wood chips and confirmed as the problematic fungi in the built-in furniture.

  • Purpose : To evaluate functional results and study factors influencing results after humeral hemiarthroplasty for comminuted fractures of the proximal humerus. Materials and Methods: We reviewed 12 patients with average follow-up period of 23 months(12 to 42). The proximal humeral fractures consisted of one anatomical neck fracture, five three-part and six four-part fractures or fracture-dislocations. Constant score and Compito et al' evaluation system were used for clinical assessment. Statistical analysis was done with the Wilcoxon test. Results: Six cases of anatomical neck, three-part fractures or fracture-dislocations showed 61 points on the average Constant score and three unsatisfactory results on the Compito et al' evaluation; Six of four-part fractures or fracture-dislocations showed 51 points and three unsatisfactory results. There were 59(two unsatisfactory) for five non-associated dislocation and 53(four unsatistactory) for seven associated dislocation; 66(one unsatisfactory) for three under 60 years and 41(five unsatisfactory) for nine over 60 years; 67(two unsatisfactory) for seven tuberosity union and 41(four unsatisfactory) for five tuberosity non-union or resorption; 58(four unsatisfactory) for ten early operation within two weeks and 43(all unsatisfactory) for two delayed operation; and 18(unsatisfactory) for one case of a accompanied rotator cuff tear. Conclusion: We concluded that tuberosity union was important factor influencing the results. Also, we thought that age, timing of operation and accompanied rotator cuff tear could be influenced to results.

  • Keeping in step with four seasons, Spring, summer, autumn, and winter, the heaven and earth(天地) has been born(生), grown(長), coverted(化), gained(收), and kept(藏) by interaction of yiyang and yuqi(五氣: 木火土金水). And according to Naiching, human being is born with energy of heaven and earth(天地之氣) and is grown with the law of four seasons(四時之法). So, we now know that the human's body and nature interact each other. The oriental medical science has been studied the effect that the nature's change influences on human body. Now, I get some idea that using herb medicine and acupuncture should have hanged following the change of four seasons. We know that there is a cycle in nature. Every day sun arise and down, and every month moon gets full and new. And every year, four seasons orderly change, from spring to winter. All of this is the law of nature and human body adapts this law. Man always shows the physiological phenomena which changes under the law of nature, especially the turning of the seasons. Therefore, we should use different medical methods in different seasons.

  • Purpose - According to the actual change of the logistics concept, the outsourcing activities of companies are actively progressing, and this is proceeding to third-party logistics and fourth-party logistics. This change in logistics situation raises the need for an in-depth understanding of four-party logistics. Research design, data, and methodology - In this study, first of all, the theoretical aspects of changes in the logistics concept are identified, along with the outsourcing and third-party logistics. Finally, the concept of four-party logistics, the background of its introduction, and future prospects will be explored. Result - The meaning of physical distribution is now passing through the existing three-party logistics and entering the era of four-way logistics. In addition, cost reduction and improvement of customer service through advanced logistics strategy can be said to be the company's competitiveness. Through this study, it can be seen that the conceptual change of logistics and the introduction of four-party logistics are closely related to the survival of the company's deficit in the market. Conclusion - In modern society, logistical competitiveness is the competitiveness of a company, and logistical activities of a company can be achieved through the process of entering the four-party logistics from the existing third-party logistics based on outsourcing. Then more customer-oriented service can be provided.

  • Symplocos Jacq. including about 350 species is the sole isolated genus of the family Symplocaceae. Despite poorly documented species delimitation and unresolved taxonomic nomenclature four species of Symplocos (S. coreana, S purnifolia, S sawafutagi, and S. tanakana) have been described in Korea. In this study, we carried the comparative wood anatomy of all the four species of Korean Symplocos to understand the wood anatomical variations within these four species. The result of this study indicated that Korean Symplocos are comparatively indistinguishable in terms of their qualitative wood features except for exclusively uniseriate rays present in S. purnifolia instead of uni- to- multiseriate in other three species. However, discrepancies are observed in quantitative wood variables such as vessel density, vessel size, and ray density. The vessel density of S. purnifolia (highest among the four species) is more than two times higher than the S. sawafutagi (lowest among the four species) and S. tanakana. On the other hand, vessel size is likewise reverse to the vessel number relationships i. e. vessel circumference and diameter in both planes of S. sawafutagi and S. tanakana is almost twice a larger than S. purnifolia. Interestingly, S. coreana remains in between of these two groups in terms of vessel features and closer to S. purnifolia in terms of ray density. The cluster analysis based on the paired group (UPGMA) algorithm using the Euclidean similarity index clearly differentiates S. purnifolia from the rest of the taxa representing the first isolated clade of the tree.

  • This study aims to investigate the effects of fashion information search and innovativeness of consumers on service quality of image search. Furthermore, it focuses on exploring the effect of image search service quality on use intention. Data of mobile-friendly consumers in their 20s and 30s was collected in September 2021 via an online survey. Finally, 300 samples were used for the data analysis. First, motivation for information search in fashion was divided into four factors: information, relation, leisure, and entertainment motivation. Furthermore, service quality of image search was divided into four factors: accuracy, convenience, customization, and aesthetics. Second, regression analysis was conducted to evaluate the effect of fashion information search motivation on service quality. As a result, it was found that information, relation, and entertainment motivation except leisure motivation had significant effects on all factors of service quality. Third, fashion innovativeness had no significant effect on aesthetics while consumer innovativeness significantly influenced all factors of service quality. Fourth, accuracy, convenience, and aesthetics had a significant effect on use intention.

  • Recognition thresholds for representatives of the salt, sweet, bitter, and sour modalities of taste were determined in 25 patients with dentures. The following results were obtained. (1) Recognition thresholds for the taste of NaCl(salt) and Sucrose(sweet) were essentially unchanged with or without the dentures in place. (2) Recognition thresholds for HCl(sour) and Urea(bitter) increased after the patients inserted their dentures. The amount of increase was 59.4% and 112.5% for HCl and Urea, respectively. (3) Recognition thresholds for all four taste modalities inpatients with ill-fitting dentures were not significantly changed with or without dentures in place. (4) Recogniton thresholds for all four taste modalities in Korean were greater than those of Pfaffamann's.

  • In many parts of the world Allium cepa, Allium roseum, Trigonella foenum graecum and Curcuma domestica are extensively used as food and are popular in herbal medicine. The four were screened against 26 pathogens and all exhibited broad-spectrum anti-bacterial activity. The aqueous as well as fractionated methanol extract of Allium cepa and A. roseum demonstrated broader level of activity against most of the organisms. On the other hand the unfractionated methanol extracts as well as the fractions of both Trigonella foenum graecum and Curcuma domestica showed broad spectrum of activity. Fractionation was found to improve their level of activity. In both cases the ethyl acetate fractions exhibited higher level of activity. All the materials tested were inactive against any of the four moulds. Allium cepa, Allium roseum, Trigonella foenum graecum and Curcuma domestica are proposed as non toxic, safe, broad spectrum antibacterial agents.
