  • Background: Morphologically classifying embryos is important for numerous laboratory techniques, which range from basic methods to methods for assisted reproduction. However, the standard method currently used for classification is subjective and depends on an embryologist's prior training. Thus, our work was aimed at developing software to classify morphological quality for blastocysts based on digital images. Methods: The developed methodology is suitable for the assistance of the embryologist on the task of analyzing blastocysts. The software uses artificial neural network techniques as a machine learning technique. These networks analyze both visual variables extracted from an image and biological features for an embryo. Results: After the training process the final accuracy of the system using this method was 95%. To aid the end-users in operating this system, we developed a graphical user interface that can be used to produce a quality assessment based on a previously trained artificial neural network. Conclusions: This process has a high potential for applicability because it can be adapted to additional species with greater economic appeal (human beings and cattle). Based on an objective assessment (without personal bias from the embryologist) and with high reproducibility between samples or different clinics and laboratories, this method will facilitate such classification in the future as an alternative practice for assessing embryo morphologies.

  • This study has been focused on understandings for the problems of dietitian who perform nutrition service in the field of industry foodservice and then focused on using of its findings as basic material for smooth nutrition service performance through analyzing job satisfaction, job characteristic and its importance of dietitians' task in industry foodservice. A questionnaire survey of 120 nutritionists who have engaged themselves in industry foodservice―60 are under direct management and 60, held in trust―has been performed, and 95 responses (79%) have been collected and categorized, except some unfinished responses. The examined data have been classified statistically by using of SPSS, and then analyzed into frequency, percentage, mean value, standard deviation, and correlation among factors, according to questionnaires. The findings of the research can be summarized as following: The details of the surveyed dietitians were: 20-25 years old on an average; working less than two years; college graduates; mere employees; receiving monthly pay of 70~100 won on an average; working more than 52 hours weekly; and providing with four meals a day in a single menu. For job satisfaction and job characteristic, the service itself and the understanding of the service appear as main features. For the relative importance of the service, the findings show that the menu making, sanitation and cost control occupy an important position, while nutrition counseling, nutrition education and dietary control by ailments make up very low portion. For the cause of not enacting the nutrition service, the lack of counseling ability and the overburden of food service are at the top. The findings of this research, therefore, present the needs of the service capacity education and the reduction of excessive foodservice hours of dietitians in order to secure the efficient nutrition service in industry foodservice. To achieve this goal, first of all, there should be an intensive education course in school by using of practice hours. for enhancing practical service adaptability, and then the computerization of foodservice should be executed perfectly to reduce the excessive foodservice hours.

  • One of the essential characteristics of Lewis Mumford's architectural criticism is the coherent emphasis on symbolism. Such emphasis stems from his understanding of city and humanity in the context of civilization: first, that the architecture symbolizes institutions of urban civilization; second, that the technical aspect of human nature should be balanced with its artistic aspects. Mumford believed that each architectural type requires an appropriate symbolic expression corresponding to its purpose and that a new symbolic expression, in a new cultural context, should replace the conventional expression. He took symbolism for an intuitional expression, and read multi-layered meanings of architecture: 'practical function' by way of rational reason and 'symbolic function' by way of intuition. He pursued a balance between practicality and beauty to rectify the situation of modern civilization, in which symbolism, the expression of its intuitional aspect, is in crisis. Ultimately, for Mumford, the essential task of architectural critic is of the interpretation of symbolism, aiming at the correspondence and communication between the architect(artist)'s intuition and critic(interpreter)'s via the media of symbol. The critic can play some privileged role of interpreting even symbols unintended by the architect. The ideal architectural critic, after all, would be the one who is able to understand the city, technology and human beings in the perspective of civilization and to interpret the architect's artistic expression in its highest form through intuition. Mumford established himself as such a critic and evaluated the status of aesthetic accomplishment of his contemporary architecture and technological civilization, giving emphasis on the artistic practice in architecture as a solution.

  • This study covers pattern differentiation based on Korean medical references, research trend and modern clinical applications about Sleep-Wake disorders of Diagnostic and Statistical Manual of Mental Disorders(DSM-V) published by American Psychiatric Association. Insomnia disorder is mostly caused by yin deficiency of liver-kidney or liver qi depression and main patterns are heart-kidney non-interaction, deficiency-excess complex pattern containing phlegm-heat due to qi stagnation and blood stasis. Hypersomnolence disorder is more due to yang deficiency rather than yin deficiency and it's major pattern is spleen-kidney yang deficiency. Cataplexy is main feature in narcolepsy and corresponds to depressive psychosis or fainting in terms of Korean Medicine and narcolepsy is assumed to be relevant to liver wind. Breathing-related sleep disorders are related with phlegm-fluid retention brought on spleen deficiency with dampness encumbrance. Pattern of circadian rhythm sleep-wake disorders is combined with yin deficiency of liver-kidney or liver qi depression of insomnia disorder and spleen-kidney yang deficiency or dampness-phlegm of hypersomnolence disorder. Yin deficiency with effulgent fire brought on drugs or alcohol is one of main patterns of substance/medication-induced sleep disorder and combined patterns with yin deficiency of liver-kidney and blood stasis or dampness-phlegm-heat are mostly applied clinically. This study drew major and frequently applied patterns of sleep-wake disorders based on Koran medical literature and modern clinical applications. And that can be the groundwork for the task ahead like clinical practice guideline of sleep-wake disorders containing pattern differentiation, diagnosis and prescriptions.

  • The purposes of the study were to analyze pre-service mathematics teachers' MKT and to examine the perceptions of MKT to find implications for the improvement of pre-service mathematics teacher education program in the aspect of teachers' content knowledge. Twenty-six pre-service mathematics teachers participated in the survey to examine the perceptions of MKT and they also finished two MKT tasks which focused on a specific area of middle school geometry. According to the survey results, the participants thought that they have enough knowledge in all categories of MKT except KCT-2 and they appreciated the importance of MKT education in pre-service mathematics teacher education program. However, the participants showed difficulties in MKT task items which required SCK, KCS, KCT, especially, the proportions of those who showed appropriate knowledge on the items required SCK and KCT was less than 50%. These results show disagreement between the perceptions of pre-service mathematics teachers' MKT and practice of MKT.

  • It is important to develop new effective technologies to increase the interruption capacity and to reduce the size of a UB(Gas Circuit Breakers). Major design parameters such as nozzle geometries and interrupting chamber dimensions affect the cooling of the arc and the breaking performance. But it is not easy to test real GCB model in practice as in theory. Therefore, a simulation tool based on a computational fluid dynamics(CFD) algorithm has been developed to facilitate an optimization of the interrupter. Special attention has been paid to the supersonic flow phenomena between contacts and the observation of hat-gas flow for estimating the breaking performance. However, there are many difficult problems in calculating the flow characteristics in a GCB such as shock wave and complex geometries, which may be either static or in relative motion. Although a number of mesh generation techniques are now available, the generation of meshes around complicated, multi-component geometries like a GCB is still a tedious and difficult task for the computational fluid dynamics. This paper presents the CFD program using CFB-CAD integration technique based on Cartesian cut-cell method, which could reduce researcher's efforts to generate the mesh and achieve the accurate representation of the geometry designed by a CAD tools.

  • Purpose: This study was conducted to examine the adaptation experience of male nurses working in general wards. Methods: Experiential data was collected from 16 general ward nurses through in-depth interviews. Participants were selected from male nurses working in the general wards with over one year of clinical experience at a tertiary university hospital. The main question was "Can you describe your adaptation experience in the general ward as a nurse?" All interviews were recorded and transcribed, then analyzed using Colaizzi's method. Results: Four categories were derived from the analysis: 'difficulties from task adaptation by characteristics', 'limited nursing situation and circumstance as a male nurse', 'efforts to adapt at general nursing unit', and 'self-worth, and worry about something as a male nurse'. Conclusion: Male nurses had a difficulty adapting to work in wards due to lack of multi-tasking skills, as well as some social prejudice or negative views on male nurses. Establishing reasonable guidelines for male nurses in practice, promoting their responsibilities to patients, developing mentoring programs, and reassessing the policy of assigning male nurses to general wards are recommended to help in better adaptation.
