Public concern on the methods of raising food-producing animals has increased, especially in the last two decades, leading to voluntary and mandated changes in the animal production methods. The primary objective of these changes is to improve the welfare of farm animals. The use of gestational stalls is currently a major welfare issue in swine production. Several studies assessed the welfare of alternative housing systems for gestating sows. A comparative study was performed with gestating sows housed in either individual stalls or in groups in a pen with an electronic sow feeder. This review assessed the welfare of each housing system using physiological, behavioral, and reproductive performance criteria. The current review identified clear advantages and disadvantages of each housing system. Individual stall housing allowed each sow to be given an individually tailored diet without competition, but the sows had behavioral restrictions and showed stereotypical behaviors (e.g., bar biting, nosing, palate grinding, etc.). Group-housed sows had increased opportunities to display such behavior (e.g., ability to move around and social interactions); however, a higher prevalence of aggressive behavior, especially first mixing in static group type, caused a negative impact on longevity (more body lesions, scratch and bite injuries, and lameness, especially in subordinate sows). Conclusively, a more segmented and diversified welfare assessment could be beneficial for a precise evaluation of each housing system for sows. Further efforts should be made to reduce aggression-driven injuries and design housing systems (feeding regimen, floor, bedding, etc.) to improve the welfare of group-housed sows.

The study aims to identify the factors affecting employee loyalty in the case of small and medium enterprises (SMEs) in Tra Vinh province, Viet Nam and to find out critical factors affecting the loyalty of employees in SMEs. This is implemented with the method of collecting primary data of 320 employees working at SMEs in 5 districts including: Cau Ngang, Tra Cu, Chau Thanh, Cang Long, Tieu Can) and Tra Vinh City, Viet Nam. Using the multivariate regression method, the researchers have found 6 factors affecting employee loyalty: colleagues, leaders, job characteristics, remuneration policies, organizational culture, and working environment. Particularly, learning opportunities may not be not statistically significant for employees' loyalty towards small and medium-sized enterprises in Tra Vinh province. From the above research results, the authors have proposed implicational piolicies such as: focusing on colleague relationships, improving leadership of business owners, attaching importance to appropriate work arrangement, having appropriate remuneration policies for laborers, building effective organizational culture and working environment to improve employee loyalty at SMEs. From the above policy implications, helping business owners realize the aspirations of workers in small and medium-sized enterprises more closely in the future, in order to sustainably develop the business system in Vietnam.

Singapore, a city state with less than 6 million population, has continued successful cooperative development and become one of the most successful Asian countries in exporting expertise in urban and real estate development. This research aims to analyze Singapore's cooperative development with socialist countries including China and Vietnam from Singapore's perspective as an investor. For cooperative development projects in China, Singapore adopted Singapore-style physical urban planning concepts as well as its own institutional and administrative systems. Singapore-Vietnam cooperative development managed to acquire profitable land and diversify its portfolio in terms of industry types and rents. This made Singapore's industrial parks more competitive than other parks in Vietnam. By showcasing successful project implementation in China and Vietnam, Singapore has proved that its model for industrial park and urban development is transferable. Singapore's success in cooperative development with socialist countries provides important implications for future cooperative development between South and North Korea. For example, phased development approaches starting from individual industrial parks expanding to mixed-use townships will be very useful to realize sustainable urban planning in North Korea and reduce financial risks. Singapore dominated development opportunities in advance when socialist countries opened their economy. To pattern ourselves after Singapore, we should not only improve our relationship with North Korea but also prepare with practical components such as financing and organizational structure.

Internal deficiency of vital Qi is origination of cancer and root cause of its development from the viewpoint of traditional Chinese medicine(TCM). For about 40 years, China has developed a combined system of TCM and Western medical system in treatment of cancers, laying stress on the therapeutic principle of strengthening the body resistance and restoring normal functioning of the body to consolidate the constitution (Fu Zheng Pei Ben). According to the results of the latest clinical and experimental studies, Chinese medicine not only increases curative effectiveness, but also reduces the side effect caused by the toxic, radio and chemical treatment of cancer cases in the western medical system as well as various complications. Long-term taking Chinese herbal medicine prevents recurrence and metastasis of tumor, and heightens long-term curative effectiveness after western medical treatments. It also helps to relieve symptoms, improve the quality of life, and prolong life of terminal cancer patients who have already lost opportunities of western medical treatments. In addition, it can prevent and cure premonitory symptoms of cancer.

Cooperative spectrum sensing (CSS) for vacant licensed bands is one of the key techniques in cognitive radio networks. Currently, sequential probability ratio test scheme (SPRT) is considered as a powerful soft decision approach to improve the sensing result for CSS. However, SPRT assumes all secondary users (SU) are honest, and thus offering opportunities for malicious SUs to launch the spectrum sensing data falsification attack (SSDF attack). To combat such misbehaved behaviors, recent efforts have been made to trust mechanism. In this paper, we argue that powering SPRT with traditional trust mechanism is not enough. Dynamic SSDF attackers can maintain high trust in an alternant process of submitting honest or false sensing data, resulting in difficultly detecting them. Noting that the trust value of dymamic SSDF attackers behave highly volatile, a novel trusted SPRT scheme (VSPRT) based on volatility decay analysis is proposed in this paper to mitigate the harmful effect of dynamic SSDF attackers in the process of the soft-decision data fusion, and thus improving the accuracy of the final sensing result. Simulation results show that the VSPRT scheme outperforms the conventional SPRT schemes.

The purpose of this research is to analyze the recognition of the curriculum experts on 2015 integrated liberal arts and natural sciences curriculum revision. Research method is a delphi survey and the subjects are curriculum experts. The research results are as follows. Firstly, experts suggested common education for all students and students' opportunities to choose subjects. Secondly, the direction of curriculum revision was different by school level. The elementary school needs to foster convergence thinking. The middle school needs to educate common basic literacy education and the high school needs both the common education and the free choice of subjects by students. Thirdly, the separation of the liberal arts and natural sciences was caused by the separate thinking of custom, tradition and study and the separate exam application on liberal arts and natural science of college scholastic ability test. The solution about separation problem of liberal arts and natural sciences have been proposed to improve mathematics education and teachers' convergence education competency. Lastly, for the establishment of an 2015, integrated curriculum the reduction of the CSAT test area and the introduction of qualifying examination for English were required.

The purpose of this study was to set and analyze the utilization of the substituted agricultural land in the Dongtan new town in Hwa-seong city. The results of this study were as follows. In the respect of the land efficiency and utilization, the need of the agricultural land in the Dongtan has shrunk. Therefore, the land should be reconsidered and developed as other purposes. The land could be developed as the weekend farm for the city people. The weekend farm is currently gaining popularity because the citizens want to not only experience the nature but also get a healthy food. So, the land in the new town could provide them with a good place. And the Han-ok(Traditional Korean style housing) is recently in the limelight of many people because of its healthy function and the special aesthetic, so the agricultural land of Dongtan could be a great opportunity to develop the Han-ok village. Lastly, the logistics center for agricultural products could be proposed. Because the traffic condition of the new town is satisfactory, the land is idealistic as the logistics center which connect the capital with the local. These practical uses of agricultural land in the Dongtan new town will be able to provide opportunities to improve the quality of life in the area and develop the land more efficiently.
