  • Companies build the factory automation system to improve management effectiveness and productivity as prime strategies for sustainable growth. But most companies undergo various trials and errors while carrying out the project without elaborate preparation stage for factory automation. In this study, we tried to verify what factors are critical to effectively building distribution automation system, which is a branch of factory automation system. A consulting model for setting up a Material Handling Automation System by utilizing the Stage-Gate Process, which is product development process was studied. 29 material handling automation projects carried out between the year 1990 to 2013 at K-Company were selected. Interviews with the project managers, operators and maintenance personnels, various records and current status of the projects were used as data for structural equations based on the Milan consulting model and existing researches of factory automation, CIM for material handling automation. Creating effective basis of production, material handling system and energy saving system with expert review, when preparing a material handling automation project, help promote the project planning thus contributing to the performance of the resulting system, which appears though rather weakly in our data. Also the effect of material handling automation can be enhanced through sufficient and effective links to the relevant environments such as production logistics management and automated warehouses. More detailed planning characteristics of project promotion or some time-series data of effective Material Handling Automation System could enhace furthur studies. We propose a consulting model for setting up an efficient material handling automation system.

  • Livestock production is the second largest economic activity of Pakistan's rural population, more specifically; sixty-seven percent of Pakistan's total population that live in rural areas sources their income from livestock activities. As this subsector of agriculture within rural Pakistan is so critical to Pakistan's economy it is especially important to further develop the sector through the introduction of cost effective, efficient, and practical technologies. In an effort to improve such an important sector within the agriculture sector in Pakistan research has been carried out to better understand the capabilities and feasibility of leveraging Internet of Things based technologies, such as, microprocessors and microcontrollers within Pakistan's livestock production and management. The internet of Things can potentially allow for the scaling of small-scale rural livestock production to larger operations through cost effective and efficient livestock management through the application of IoT technologies. This paper discusses the architecture models of IoT based smart animal farms and delves into the pitfalls and advantages of applying IoT technologies in this sector. In this work we will explore the cheap sensors to monitor the internal activities of cattle farm with the aim of using these sensors as part of system to detect the important operations that need on the time response. This system should provide the feed and water as required, and control the temperature in sheds to protect the cattle being ill and on heat, and humidity level .internet connection used to connect these devices with smartphones or computers. In this paper we proposed the architecture model of IoT based smart animal farm.

  • This study was aimed to examine kindergarten teachers' concerns in physical computing, which corresponds to the innovative teaching method, based on CBAM. For this, a questionnaire survey was conducted targeting 118 kindergarten teachers. Percentile analysis and MANOVA using CBAM model were carried out. As a result of the research, the kindergarten teachers' concern level is analyzed to be a critical non-user pattern on the whole. However, a pattern aspect was shown with a slightly high concern in stage 1, stage 2 and stage 3 compared to a typical type, and with a low concern level in stage 4. In consequence of having implemented MANOVA, the private kindergarten teachers' concern level appeared to be significantly high in stage 4 and stage 6 compared to a public kindergarten. Also, compared to the teachers who plan to utilize physical computing from now on, the teachers who don't have a plan of the application had significantly high concern level in stage 0. The concern level score was significantly low in 1~6 stages excluding stage 3.

  • This research is an attempt to newly interpret his academic evaluation and understand Seo Kye Bak Se-Dang's Sa Byeun Rok The Doctrine of the Mean. In academic world, his academic Characteristic was considered as anti-Neo-confucianism, out of Jung Ju Hak, out of Seong Ri Hak, and Sil Hak. His understanding of The Doctrine of the Mean was pretty critical, because he had unique academic characteristic to interpret Chinese classics rather than anti-Neo-confucianism, out of Jung Ju Hak, out of Seong Ri Hak, and Sil Hak. Especially, he took practical study with six Chinese classics as the central figure and it was a creative thing with philosophical method. He tried to find out original meaning which was essential thought of Confucianism, and pointed out disharmony for consistency about meaning of The Doctrine of the Mean when Jung Ja and Ju Ja interpreted The Doctrine of the Mean. It appeared as an effort of trying agreement between name and its duty, and role and function in things and act. In addition, he thought The Doctrine of the Mean as trying to follow nature, and it was the way of people to practice in bright side of mind. It is different from Ju Ja's thought which explains principle about people and things, and it has strong reality which is foundation of practice and allows dynamic energy of human life. Therefore, practice style of The Doctrine of the Mean develops filial duty as center of mass and appears manifestation of human's independence through how people pracice it. To sum up, he traced The Doctrine of the Mean as reality, practice, and physical science rather than ideal, theoretical, and metaphysical philosophy. It developed the spirit of study as understanding world as the center of human, thinking over the way of people, and studying the essence of Confucianism with practice of thought.

  • When sound waves propagate over long distances in shallow water, measured transmission loss is greater than predicted one using underwater acoustic model with the Rayleigh reflection model due to inhomogeneity of the bottom. Accordingly, the US Navy predicts sound wave propagation by applying the empirical formula-based High Frequency Bottom Loss (HFBL) model. In this study, the measurement and analysis of transmission loss was conducted using mid-frequency (2.3 kHz, 3 kHz) in the shallow water of the East Sea in summer. BELLHOP eigenray tracing output shows that only sound waves with lower grazing angle than the critical angle propagate long distances for several kilometers or more, and the difference between the predicted transmission loss based on the Rayleigh reflection model and the measured transmission loss tend to increase along the propagation range. By comparing the Rayleigh reflection model and the HFBL model at the high grazing angle region, the bottom province, the input value of the HFBL model, is estimated and BELLHOP transmission loss with HFBL model is compared to measured transmission loss. As a result, it agrees well with the measurements of transmission loss.

  • This study aims to examine whether emotional clarity predicts low levels of social interaction anxiety among senior citizens and to verify whether self-esteem and self-efficacy play a critical role as mediators between them. An online survey measuring emotional clarity, social interaction anxiety, self-esteem, and self-efficacy was conducted with 217 Korean senior citizens. The analysis revealed that emotional clarity in old age predicted lower social interaction anxiety. Besides, self-esteem mediated the relationship between emotional clarity and social interaction anxiety, while self-efficacy did not produce consistent results. That is, recognizing one's emotions increases one's self-esteem, which reduces social interaction anxiety, but this mediating effect could not be confirmed through self-efficacy. This result emphasizes that recognizing one's emotions in old age is an important factor in facilitating interaction with others, and shows that individuals can be comfortable in relational situations because emotional clarity increases one's self-esteem. Finally, the implications of this study and the future direction of this research area were discussed.

  • The purpose of this study is to explore the direction of multicultural mentoring class activities in order to promote the professional growth and critical reflection of student mentors who are undergraduate students from a variety of major. For this purpose, the contents and phenomena of the multicultural mentoring of the mentor - mentee were reported as activity texts, and then seven directions of textuality were applied to explore the direction of multicultural mentoring class activities. As a result, coherence refers to the relationship between the mentor and the mentee for continuing the activities of multicultural mentoring, and cohesiveness refers to the relationship between the mentor and the mentee. It was called the achievement of identity. Intention means that the mentor has an intention or goal for the class before the mentoring activity, and tolerance means that the text produced by the mentor in the multicultural mentoring process is accepted by the mentee. Intentional means that the mentor has intention or goal for the class before the mentoring class activity, and tolerance means having the text as the class activity text when the mentor's text is accepted by the multicultural mentoring class activity process. In the case of informativeness, the information produced by the mentor is less informative when the mentee is predictable and less informative when the predictor is low. In the case of contextuality, contextuality of class activities can be changed according to the physical text situation and the mentee situation in class activity. In case of multicultural mentoring class activity, except for case where mentor creates new class activity text, it is related to the production of class activity texts through mentor learning experiences, peer friends' advice, and education.

  • Deep learning models based on generative adversarial neural networks are specialized in generating new information based on learned information. The deep generative models (DGMR) model developed by Google DeepMind is an generative adversarial neural network model that generates predictive radar images by learning complex patterns and relationships in large-scale radar image data. In this study, the DGMR model was trained using radar rainfall observation data from the Ministry of Environment, and rainfall prediction was performed using an generative adversarial neural network for a heavy rainfall case in August 2021, and the accuracy was compared with existing prediction techniques. The DGMR generally resembled the observed rainfall in terms of rainfall distribution in the first 60 minutes, but tended to predict a continuous development of rainfall in cases where strong rainfall occurred over the entire area. Statistical evaluation also showed that the DGMR method is an effective rainfall prediction method compared to other methods, with a critical success index of 0.57 to 0.79 and a mean absolute error of 0.57 to 1.36 mm in 1 hour advance prediction. However, the lack of diversity in the generated results sometimes reduces the prediction accuracy, so it is necessary to improve the diversity and to supplement it with rainfall data predicted by a physics-based numerical forecast model to improve the accuracy of the forecast for more than 2 hours in advance.
