Purpose : The most patients with acute streptococcal pharyngitis lack of classic clinical manifestations, therefore diagnostic laboratory test such as the throat culture or a rapid antigen detection test are frequently employed in primary practices of developed countries. We'd like to know the accuracy of the throat swab culture as gold standard for diagnosis of streptococcal infection with studying the discordant and concordant rate of duplicate culture. Methods : The study included 89 normal school children (boys:50, girls:39) who were attending Uljin primary school in Uljin, Kyong Sang Buk Do on March 1996. We obtained simultaneous 2 times of throat swab from each subject, and plating and streaking on 5-7% of sheep blood agar separately. We counted the characteristic beta-hemolytic colonies after overnight incubation. Results : 1) The carrier rate of beta-hemolytic streptococci at first culture is 25.1% and second one is 29.2%. 2) Ten out of 89(11.2%) is discordant in duplicate culture. 3) Culture containing less than 50 colonies of beta-hemolytic streptococci (+2) in first culture is 70.4%, second one is 85.7%. 4) Number of colonies is less than 50 in all ten discordant children. Conclusions : The discordant rate of duplicate throat swab cullture for beta-hemolytic streptococci is 11.2%, even if the subjects are normal school children. About 5% of individuals harboring beta-hemolytic streptococci in the pharynx may be missed by a single throat culture. If we are trying to examine the patients with pharyngitis, the discordant rate will be much lower than this results.

In this study, uptake and translocation of 2,4,6-trinitrotoluene(TNT) by plant in a hydroponic culture was quantified with two indigenous plant species, Aeschynomene indica and Abutilon avicennae on various initial concentrations of TNT ranging from 20 to 80 mgTNT/L. Experiments were sterilized to exclude the activity of microorganisms and conducted in duplicate. Weight loss of two plant species in added TNT culture media was higher than in control. At over 2OmgTNTIL, there appeared to be phytotoxicity from TNT as indicated by severe yellow-chlorosis and increase of falling leaves. TNT removal rate normalized(K) to the plant fresh weight of Abutilon avicennae and Aeschynomene indica was that the higher TNT concentrations resulted in lower TNT removal rate normalized(K) to the plant fresh weight. Approximately 96% of the TNT in viable microflora-hydroponic culture was removed after 96h of the experiments.

Purposes: In this study, we examined the factors which silenced the organizing members and how the factors affects deprivation of employment about the organization culture, the organizational silence, and the turnover intention. Methodology: In order to research, we carry out a survey on 400 employees of small and medium hospitals. Among them, 321 questionnaires were used for actual analysis, excluding insincere respondents, non-responders or duplicate respondents. In order to verify the hypotheses in this study, we conduct the covariance Structural Equation Model(SEM). Finding: We obtained results using following hypotheses. First, ''The organization culture has an effect on the turnover intention.'' Second, ''The organization culture has an effect on the organizational silence'' Third, ''The organizational silence has a influence on the turnover intention.'' Finally, ''When the organization culture mediates the organizational silence, the adaptation relationship of the ornization effectiveness is different.'', as the key hypothesis, showed that the agreement culture, rational culture, and hierarchical culture of the organization culture type were statistically significant. The organizational silence as a parameter has the partial mediating effects(-) because it has direct and indirect effects. Practical Implications: The results of this study showed that the reason for the organizational silence of the organizing members is that the organization culture by a grade of rank is the largest and these the organizational silence affects the turnover intention.

Generally, disabled people have a lot of bad health status at low income levels, the need for health care is higher than for non-disabled people. Although the number of persons with disabilities is increasing with each passing year, their medical services and support are still limited and limited. This problem is not so different from approach to medical information. Conventional medical information is usually printed and transmitted to the patient, but visually impaired people have difficulty accessing such printed information. In the case of the visually impaired, there are many cases where it is not possible to read not only the printed letter but also the braille because the acquired incidence is high. Therefore, this paper tried to solve this problem by transmitting the information of medicine by voice using RFID. In addition, ontology was used to select more accurate drug information. Currently, there are drug information sites provided by the Ministry of Health and Welfare. However, since duplicate information is scattered on these sites, the ontology was used to build up the database.

With the development of sequencing technology, there is a need for technology to predict the function of the protein sequence. Enzyme Commission (EC) numbers are becoming markers that distinguish the function of the sequence. In particular, many researchers are researching various methods of predicting the EC numbers of protein sequences based on deep learning. However, as studies using various methods exist, a problem arises, in which the exact prediction result of the sequence is unknown. To solve this problem, this paper proposes an All Enzyme Commission (AEC) algorithm. The proposed AEC is an algorithm that executes various prediction methods and integrates the results when predicting sequences. This algorithm uses duplicates to give more weights when duplicate values are obtained from multiple methods. The largest value, among the final prediction result values for each method to which the weight is applied, is the final prediction result. Moreover, for the convenience of researchers, the proposed algorithm is provided through the AllEC web services. They can use the algorithms regardless of the operating systems, installation, or operating environment.

In the 1990s, university environment is changing rapidly(especially, difficulty of student registration which are originated student's decrease and various deregulation) and university get ready for the new ways of management culture. This new ways are management innovation strategies. The purpose of this study is to suggest the direction of effective innovation(to search application possibility of management innovation strategy), solving the problems occurred by the enlargement and change in the environments of universities. From early in the 1990s, korean corporations perform actively many management innovation strategy including benchmarking, restructuring, downsizing, zero-based budgeting, BPR, learn organization and total quality management. But korean most universities performed hardware management innovation strategies such as corporate portfolio restructuring(including outsourcing, M&A, MBO etc.) and organization restructuring. Therefore korean universities have got to concerns about more software management innovation strategy such as total quality management and learn organization. Also we have seen another problems such as that universities try to merely duplicate certain management innovation strategies which are used by another university. rather than to make various effort to adequate their own organizations. In conclusion, korean universities are to play an important roles in the development of knowledge society. The management innovation and individual competence development in the university are required to overcome crisis of university.

Purpose: Through an ethical supply chain, brands not only catch the eye but win over a fan base of consumers who prize credibility and consistency in what they purchase. Currently, the ethical supply chain is no longer just a manufacturing process; it has become a compelling story. It draws people's attention and wins their loyalty. This research study will examine the benefits of an ethical supply chain in attracting consumer attention and building brand loyalty. Research design, data and methodology: For this research study, A detailed method was used to search and analyze relevant articles. Initial searches used set terms in certain databases. Screening criteria were the thorough scrutiny of titles and abstracts to decide their relevance to the study at hand. Thus, to enhance the quality of data, duplicate entries were deleted. Results: Based on the analysis of the prior literature, the results highlight the power of ethical saliency, showing that consumers themselves are looking for and rewarding products that meet their ethical standards. This attention to ethically transparent brands, in turn, encourages more interest and interaction with them. Conclusions: Therefore, practitioners must transmit the firm's ethical standards through all channels of communication-investor relations materials and financial reports alike.

A growth study was conducted to investigate the effect of stocking density on performance of juvenile fat cod (Hexagrammos otakii Jordan et Starks.). Fish averaging 13 g were stocked into duplicate tanks ($250\;{\ell}$ each) at four different densities of 330 g/$100\;{\ell},\;660\;g/100\;{\ell},\;990\;g/\;100\;{\ell}$, and $1330\;g/100\;{\ell}$, and fed MP diet containing $50\%$ frozen horse mackerel and $50\%$ commercial binder meal for 2 months. Weight gain, feed efficiency, survival rate, and protein retention were decreased as density increased. Whereas these parameters were not significantly different (P>0.01) fish stocked at initial stocking densities of $330\;g/100\;{\ell},\;660\;/g/100\;{\ell}\;and\;990\;g/100\;{\ell}$. Moisture and lipid content of whole body were not affected by stocking densities (P>0.01). These results indicate that stocking density should be considered, and $1{\~}2$ kg fish/$100\;{\ell}$ final stocking density for juvenile fat cod could be used to decrease production cost for the indoor tank (culture) system.

Eosinophils are known to be important effector cells in pathogenesis of asthma. The elucidation of mechanism by which eosinophil survival is regulated in vivo at sites of inflammation is critical tn our understanding of asthma pathogenesis. The maintenance of these cells at site of inflammation depends upon tile balance between its tendency to undergo apoptosis and tile local eosinophil-viability enhancing activity, Qualitative and quantative phenotypic differences have been observed between bronchoalveolar lavage (BAL) and peripheral blood (PB) eosinophils (EOS). We hypothesize that BAL EOS Possess altered functional feature compared to PB EOS. BAL and PB EOS were obtained from ragweed allergic asthmatics after segmental antigen challenge (SAC) at 24 hour or one week, and purified over percoll and CDl6 negative selection. Cells were cultured in duplicate in RPMI, 15% FCS and 1% penicillin/streptomycin without exogenous cytokines. Eosinophil purity and viability was >92%. BAL. EOS viability was 69${\pm}$4.4% versus 39${\pm}$1.6% for PB EOS (p<0.005) at 48 hour time point, and this difference was maintained through day 5 (32${\pm}$7.6% vs. 3.0${\pm}$ 1.4%, p<0.05), Among BAL EOS, those harvested one week after SAC appeared to have an prolonged survival compared to those harvested at 24 hour. Coculture of BAL and PB EOS resulted in significant viability enhancement than expecteed. Direct neutralization of GM-CSF activity, not IL-3 and EL-5, markedly decreased tile survival of BAL EOS in culture, and abrogated tile viability enhancing activity of their culture supernatants in a dose dependent manner. We conclude that BAL EOS activated in vivo possess enhanced viability compared to PB EOS. Mixing and neutralization experiments suggest a role for autocrine production of GM-CSF.

Railroad construction requires a lot of budget, manpower, and equipment, and as a result, many accidents occur. Although efforts are being made at the national level to reduce the accidents at railway construction sites, the occupational accident rate is not showing a downward trend. Various efforts are needed to reduce accidents, the application of smart construction safety technology will be effective. However, if smart construction safety technology is introduced indiscriminately without analysis, duplicate investment may occur, which may lead to a waste of budget for railway construction. In this regard, this study analyzes accident cases at railroad construction sites through a survey of stakeholders and proposes smart construction safety technologies to be effective for those accident types.
