As the world population grows and developing countries become more affluent, the global consumption of meat will increase by more than 50% within the next 10 years. Confronting the increased demand for poultry food products are emerging field diseases, increasing regulatory bans of antimicrobial growth promoters, high-density growth conditions, and waste management. Although biotechnology offers solutions to some of these challenges, basic studies are needed to better understand the complex interaction between the intestinal microbiome, host immunity and the environment. This presentation will focus on emerging strategies to enhance gut immunity and to decrease economic losses due to poultry diseases. This presentation will highlight recent developments in coccidiosis research and provide information on host immunity, immunomodulation, and the latest advances in dietary and nutritional approaches against coccidiosis. Such information will magnify our understanding of host-parasite biology, mucosal immunology, and design of future nutritional interventions and vaccination strategies for coccidiosis.

Objective: The goal of this study is to design a creative tutoring service, which helps children gain confidence and creativity through learning activities. Background: Nowadays most kids are growing up in a very competitive environment under their parents' zeal for education. A stressful environment can deter a child from the confident undertaking of challenges, leading to depression, anxiety, and feelings of inadequacy. Art therapy helps children work through these issues, however the process led by instructors or parents, and kids still feel anxious studying adults' face to read their thought. Method: To help children address challenges, a creative tutoring service application can provide images with certain tasks instead of asking them to fill in blank areas. The tasks asked by the service system are 1) to visualize children's own experience utilizing visually associated images from given images and 2) to create an illustrated story modifying and re-composing given images. Another task is to learn basic math and words with numbers and alphabets in customized colors. By completing each task children collect awards, which allow them graduate to higher levels of challenges. The outcomes from the tasks are sent to the main server system and reviewed by analysts. Those results are sent to children's parents as a text message on smart phone. Results: Visual implication using images inspires children to make creative stories based on their own experience. Also, children can find their own patterns of reaching answers by using synaesthetic imagery through repetitive practices of creative thinking tasks. Conclusion: Understanding how they feel about doing tasks in certain environments and assessing them in varied situations should be carefully considered when designers approach service design for kids. By focusing on how to tutor children in creative ways, as opposed to focusing on the expected outcome, creative service applications can be designed to reduce children's stress and encourage self expression. Children are predicted to gain confidence through using the service without the concern of comparison by others. Application: The creative tutoring service needs to be developed and tested by varying types of children.

Objective: This study aims to implement a non-contact gesture-based interface for presentation purposes and to analyze the effect of the proposed interface as information transfer assisted device. Background: Recently, research on control device using gesture recognition or speech recognition is being conducted with rapid technological growth in UI/UX area and appearance of smart service products which requires a new human-machine interface. However, few quantitative researches on practical effects of the new interface type have been done relatively, while activities on system implementation are very popular. Method: The system presented in this study is implemented with KINECT$^{(R)}$ sensor offered by Microsoft Corporation. To investigate whether the proposed system is effective as a presentation support tool or not, we conduct experiments by giving several lectures to 40 participants in both a traditional lecture room(keyboard-based presentation control) and a non-contact gesture-based lecture room(KINECT-based presentation control), evaluating their interests and immersion based on contents of the lecture and lecturing methods, and analyzing their understanding about contents of the lecture. Result: We check that whether the gesture-based presentation system can play effective role as presentation supporting tools or not depending on the level of difficulty of contents using ANOVA. Conclusion: We check that a non-contact gesture-based interface is a meaningful tool as a sportive device when delivering easy and simple information. However, the effect can vary with the contents and the level of difficulty of information provided. Application: The results presented in this paper might help to design a new human-machine(computer) interface for communication support tools.

An eight-year-old, 28-kg male bull terrier who showed signs of lethargy and cough was referred for further evaluation of congestive heart failure. On presentation, physical examination revealed a systolic murmur at the left apex of the heart. Moreover, chest radiograph evaluation confirmed the mild alveolar and interstitial patterns in the caudal lung lobes and a grossly enlarged left atrium and left ventricle. Electrocardiography showed atrial fibrillation with a wide QRS complex, and transthoracic echocardiography revealed marked enlargement of the left atrium with abnormal morphology of the mitral valve. The thickened, hammer-like appearance and abnormal diastolic motion of the mitral valve leaflets were characterized by decreased leaflet separation and doming of the valve. The diagnosis was mitral stenosis with congestive heart failure and atrial fibrillation. The owner declined interventional valvuloplasty. Medical treatment included furosemide, pimobendan and diltiazem.

Background: 6-year College of Pharmacy curriculum had started in Korea, and the students in college of pharmacy are supposed to have student practice in the hospital pharmacy, community pharmacy, pharmaceutical company and administration to experience the role of pharmacists in advance. However, despite Korean Association of Pharmacy Education provided its own teaching plan, most Pharmacy Schools and the hospital pharmacy have difficulty in performing the desirable student practice program because they seldom experienced it. So, we reported the student practice program in the hospital pharmacy conducted by Yonsei University College of Pharmacy prior to the other numerous universities and the evaluation of survey on the student pharmacy practice program. Method: Severance Hospital, Gangnam Severance Hospital and National Health Insurance Service Ilsan Hospital took part in the student pharmacy practice program of Yonsei University. Students took 8-week pharmacy practice in Severance Hospital or Gangnam Severance Hospital plus 4-week pharmacy practice in National Health Insurance Service Ilsan Hospital. Also, students had once-a-week presentation class at school. A survey was conducted to evaluate the student practice program. Results: The presentation class was considerably helpful to share their own experiences at different practice sites in different hospitals, but there were some disadvantages that students could not experience the specific pharmacy practice site on the day of once-a-week presentation at school and so on. The results of the survey on the student practice program reported that students were satisfied with the overall practice program and presentation class at school. Also, they answered that the student practice program in the hospital pharmacy was significantly helpful for planning of the future career. Conclusion: Through the performance of the student practice program in Yonsei University, the adjustment of the student practice program in the hospital is planned to provide better experience of practice to the students and the results will be helpful for the student practice in the hospital of the other colleges of pharmacy.
