In tropical and subtropical regions with high temperature and humidity conditions, one of the problems in dairy farm management is the effect of heat stress on animal productivity. Due to this problem, the utilization of an automatic environmental monitoring system for cooling, labor-saving and heat stress reduction is necessary. In this study, an environmental monitoring and automatic cooling system based on an embedded system for dairy farms was designed. The system aims to regulate the environmental condition by means of direct feedback depending on the monitoring of heat stress index (HSI) augmented by dairy cow drinking behavior. The system is composed of two sub-systems: data acquisition and environmental control. The data acquisition module collects images, temperature and humidity data. The cooling system is controlled based on the real-time environmental data, and the historical data are recorded and uploaded to the server for display and analysis. The data are analyzed on the environmental monitoring panel on the farm and on the website, which can be remotely accessed. The control parameters are adjusted using the image results from the dairy cow drinking behavior with a fixed time interval. The results of the conducted experiments show that there is labor saving improvement and an increment in milk production compared to the same period in the previous year when the system was not installed. The automatic environmental monitoring cooling system exhibits high efficiency and can perform real-time control and self-adjustment. The system can be used for fully automated dairy cow system application, as well as dairy cow behavior analysis through both environmental and image information.

An Imaging System for Monitoring the Feeding Behavior of Dairy Cows

( Cheng-yu Kuan ),( Yu-chi Tsai ),( Chen-yu Cheng ),( Jih-tay Hsu ),( Shih-torng Dnig ),( Ta-te Lin ) 한국농업기계학회 2018 한국농업기계학회 학술발표논문집 Vol.23 No.1

In sub-tropical countries, dairy cows tend to experience heat stress problems. This phenomenon may lead to declines in feed intake, milk production, and fertility. Under normal conditions, the dairy cows have a regular feeding and drinking time. For this reason, changes in feeding behavior can be a possible indicator to detect heat stress phenomena that can help farm owners monitor dairy cow health. In order to monitor and record the feeding behavior of dairy cows, an imaging system is proposed herein. The imaging system uses Raspberry Pi 3, as the embedded system, and a camera module to acquire images for dairy cow face detection in front of the feeding area to confirm if the dairy cow is eating. The dairy cow faces are detected through cascade-AdaBoost algorithms which can automatically select weak classifiers to form a strong classifier with fast processing speed in an embedded system. The factors affecting the performance of the dairy cow face detection algorithm have been tested and optimized. The system has been tested in a feeding area in National Taiwan University’s dairy farm, which has 25 dairy cows in total. By converting the frequency of dairy cow face detection into feeding time, the feeding behavior of grouped dairy cows can be analyzed. Furthermore, combining the temperature humidity index (THI) and feeding behavior can provide the farm owners with an index to evaluate the level heat stress of dairy cows.

Yu-Shiu SHIH,Dr. Wei-Te LIU 한국직업자격학회 2017 한국직업자격학회 학술대회 Vol.2017 No.10

The purpose of this study is to study the effect of Chinese medicine aromatherapy on olfactory conduction course design, which is based on the action research method design and individual research. The research object background is a 62-year-old female office worker, who is a Management Adviser in a public telecommunications company. The method adopted is pre-test and post-test method, for 4 weeks period; for the first two weeks pre-test , is to fill in the pressure index measurement table, insomnia self-rating table, and morning and evening record of blood pressure and pulse and sleep time. For the third week, before going to bed, started to use lavender highland essential oil diluted with Simmondsia chinensis vegetable oil to release stress and help to sleep, which can be directly smeared on philtrum and continue to record morning and evening (blood pressure BP), ( Pulse P) and sleep time. For the fourth week, started the post-test and then filled out the pressure index measurement table, insomnia self-rating table, and data analysis of case free writing; for the pre-test, the morning and early blood pressure pulse were 114 / 58mmHg P62 & 105 / 53mmHg P65 and for sleep, every day average sleep time was 7 hours and 21 minutes. And for post-test, the average daily sleep was 7 hours and 1 minutes, while morning and evening blood pressure pulse were 114 / 57mmHgp 63 & 107 / 55mmHg P69.Stress index measurement table for the pre-test, there were 10 questions with answer yes, 2 questions with answer no, while for the post-test, there were 5 questions with answer yes and 7 questions with answer no. Insomnia self-rating table for the pre-test was 12 points and 5 points for the post-test, and from these results for the study we can learn that the introduction of Chinese medicine aromatherapy olfactory conduction program actually can help the elderly to release stress and sleep well. This study suggests that the promotion of Chinese medicine aromatherapy olfactory conduction course and the establishment of personal health self-management habits could not only adjust the balance of body and mind at daily time but also improve insomnia caused by stress, and then improve the quality of life; especially due to daily records self-view and management, if necessary, it could timely provide effective medical data for reference so as to reduce the cost of medical expenses.

Tracing the origin of fish without hatchery information: genetic management of stock enhancement for mangrove red snapper (Lutjanus argentimaculatus) in Taiwan

Stock enhancement is considered to be a valuable approach for restoring fishery resources. Because no specific official institution in Taiwan is responsible for the production of fry, the released fry are purchased directly from the private sector. However, fishermen from the private industry have not established a genetic background, so the genetic composition for each batch of released fry is unclear. Mangrove red snapper (Lutjanus argentimaculatus), a prominent species released in Taiwan, was collected after its official release. One hundred and two field samples were compared with four batches of hatchery fry (n = 685) by using a microsatellite-based multiplex PCR assay. Four of the field samples (3.9%; 4/102) were revealed to be from a fish farm and most likely from a single batch. This study revealed that wild mangrove red snappers are genetically different from those originating from farms, and their origins can be traced through molecular markers, even without information on breeding stocks.

Osteoporosis and its associated fragility fractures are becoming a severe burden in the healthcare system globally. In the Asian-Pacific (AP) region, the rapidly increasing in aging population is the main reason accounting for the burden. Moreover, the paucity of quality care for osteoporosis continues to be an ongoing challenge. The Fracture Liaison Service (FLS) is a program promoted by International Osteoporosis Foundation (IOF) with a goal to improve quality of postfracture care and prevention of secondary fractures. In this review article, we would like to introduce the Taiwan FLS network. The first 2 programs were initiated in 2014 at the National Taiwan University Hospital and its affiliated Bei-Hu branch. Since then, the Taiwan FLS program has continued to grow exponentially. Through FLS workshops promoted by the Taiwanese Osteoporosis Association (TOA), program mentors have been able to share their valuable knowledge and clinical experience in order to promote establishments of additional programs. With 22 FLS sites including 11 successfully accredited on the best practice map, Taiwan remains as one of the highest FLS coverage countries in the AP region, and was also granted the IOF Best Secondary Fracture Prevention Promotion award in 2017. Despite challenges faced by the TOA, we strive to promote more FLS sites in Taiwan with a main goal of ameliorating further health burden in managing osteoporotic patients.

Angiotensin II (Ang II) is a very important cardiovascular disease inducer and may cause cardiac pathological hypertrophy and remodeling. We evaluated a Chinese traditional medicine, alpinate oxyphyllae fructus (AOF), for therapeutic efficacy for treating Ang II-induced cardiac hypertrophy. AOF has been used to treat patients with various symptoms accompanying hypertension and cerebrovascular disorders in Korea. We investigated its protective effect against Ang II-induced cytoskeletal change and hypertrophy in H9c2 cells. The results showed that treating cells with Ang II resulted in pathological hypertrophy, such as increased expression of transcription factors NFAT-3/p-NFAT-3, hypertrophic response genes (atrial natriuretic peptide [ANP] and b-type natriuretic peptide [BNP]), and Gαq down-stream effectors (PLCβ3 and calcineurin). Pretreatment with AOF (60–100 μg/mL) led to significantly reduced hypertrophy. We also found that AOF pretreatment significantly suppressed the cardiac remodeling proteins, metalloproteinase (MMP9 and MMP2), and plasminogen activator, induced by Ang II challenge. In conclusion, we provide evidence that AOF protects against Ang II-induced pathological hypertrophy by specifically inhibiting the insulin-like growth factor (IGF) II/IIR-related signaling pathway in H9c2 cells. AOF might be a candidate for cardiac hypertrophy and ventricular remodeling prevention in chronic cardiovascular diseases.

Background : Since the first successful kidney transplantation from a brain death donor(BDD) was done in 1979, organ transplantations from BDD have steadily increased. The number of BDDs have been increasing year by year. The purpose of this study is to analyze clinical status of organ donor from BDDs. Methods : We analyzed retrospectively the status of BDDs registerd for organ transplant program in Asan Medical Center from January, 1992 to March, 1997. Results: The male to female ratio was 3 : 1, and the age distribution was the highest in twenties. The distribution of cause of brain death was the highest in motor vehicle accidents. The distribution of acquired organ was the highest in kidney, heart, liver in order. The distribution of days stayed in ICU before organ donation was the highest in 2 days. The choice of agent for inotropic support of the myocardium is dobutamine. The donors have been transfused with packed red blood cell(PRBC) to maintain the hematocrit between 25∼35%. Two units of PRBC should be readily available at all times for transfusion. The failure of organ donation was mainly very poor organ condition. Conclusions : We wish that these results were made use of bases of status of organ donation from BDDs. (Korean J Anesthesiol 1998; 34: 160∼166)

Hao-Te LU,Wan-Yu,HSU,Chih-Yao,YI 세계문화관광학회 2012 International Journal of Culture and tourism Resea Vol.5 No.1

Customers usually like to make travel plans weeks or months ahead of the travel schedule. Therefore, they can take extra time to search information they need in order to purchase the products at the lowest possible price. Accordingly, this study bases on the revenue management (or yield management) to examine the prices of two categories, airplane tickets and hotels, over a period of eight weeks in order to observe how the prices cycle up and down over time. The aim of this study is to investigate whether there is an optimal purchasing time for any of the products. A structured observation, often also called systematic observation was conducted by this study to investigate the two categories of travel products. The study reveals that prices for the products assume an increasing trend as the date of the product consumption approaches. The implication for consumers is that they could purchase the products as early as possible to take advantage of the early prices. Although prices sometimes drop, they rarely drop lower than those the first day consumers start their search for tourism products. At end of this study, we also discuss the price variation in Taiwan and an avenue for further research.
