The Current Status of General Health Education Curriculum in Technical Institutes and Universities in Taiwan  [PDF]
Su-Chang Chen
Creative Education (CE) , 2010, DOI: 10.4236/ce.2010.11010
Abstract: The purpose of this study is to understand the current status of the establishment of “general health education curriculum” by technical institutes and universities in Taiwan. A questionnaire survey method was used. A total of 75 questionnaires were sent and 41 were returned; the valid return rate was 54.7%. The result showed that the courses on general health can be categorized into four groups: physiological, psychological, nutritional, and fitness health. Group the curriculum by academic fields, and the natural sciences are the course offered by most schools. Group the curriculum by subjects, and courses offered by non-medical institutes focused mostly on psychological and lifestyles (health psychology), while that of the medical-related institutes offer most curriculums in health management (health promotion, health-related physical fitness), health and exercise, medicine and lifestyles (healthcare and life) and nutrition.
Optimal Operating Policies for a Multinational Company under Varying Market Economics  [PDF]
Shu-Chen Chang
Modern Economy (ME) , 2013, DOI: 10.4236/me.2013.411073
Abstract: This paper proposes a mathematical programming model for Multi-National Corporations (MNCs) by considering both the flexibility of exchange rate and market price uncertainties. The results show that the factory in a host country should supply the products demanded by the home country for the next period when exchange rate decreases. The quantity of products being produced and shipped should be adjusted according to the variation of market-price. Conversely, a MNC in the host country should produce products ahead of time when exchange rate increases and must adjust quantity of production and inventories according to the variation of market-price.
Knowledge Discovery from Dynamic Data on a Nonlinear System  [PDF]
Chen-Sung Chang
Open Journal of Applied Sciences (OJAppS) , 2015, DOI: 10.4236/ojapps.2015.510056
Abstract: A method is presented for performing knowledge discovery on the dynamic data of a nonlinear system. In the proposed approach, a synchronized phasor measurement technique is used to acquire the dynamic data of the nonlinear system and a hyper-rectangular type neural network (HRTNN) is then applied to extract crisp and fuzzy rules with which to estimate the system stability. The effectiveness of the proposed methodology is verified using the dynamic data of a typical real-world nonlinear system, namely an AEP-14 bus, and the extracted rules are relating to the knowledge discovery of the stability levels for the nonlinear system. The discovered relationships among the dynamic data (i.e., the operating state), the extracted rules, and the system stability are confirmed by means of a two-stage confirmatory factor analysis.

Molecular cloning, expression and characterization of a novel geneβ-N-acetylglucosaminidase from Bombyxmori  [PDF]
Cheng Chang, Xiaoyong Liu, Keping Chen
Advances in Bioscience and Biotechnology (ABB) , 2011, DOI: 10.4236/abb.2011.23019
Abstract: Previously, we have reported that a gene encoding Bombyxmoriβ-N-acetylglucosaminidase 2 (BmGlcNAcase2) has been identified differentially expressed in the midgut of Bombyxmori strain NB resistant to nucleopolyhedrovirus (BmNPV), strain 306 susceptible to NPV and a near isogenic line BC9 with similar genetic background to 306 but resistant to NPV by two-dimensional gel electrophoresis (2-DE). To get more knowledge about the relationship between β-N-acetylglucosaminidase and the resistance of NPV, in this study, the 1542 bp open reading frame of a putative bombyxmoriβ-N-acetylglucosaminidase 2 gene (BmGlcNAcase2) was amplified from a pool of bombyxmoricDNAs and inserted into the prokaryotic expression plasmid pET-30a(+).Western blotting analysis showed that BmGlcNAcase2 was expressed in hemolymph, ovary, testis, fat body, trachea, midgut and silk gland of fifth instar larvae respectively . Immunofluoresence analysis indicated that BmGlcNAcase2 was mainly located to the cytoplasm or some structure in cytoplasm.
Using Microgripper in Development of Automatic Adhesive Glue Transferring and Binding Microassembly System  [PDF]
R. J. CHANG, C. C. CHEN
Engineering (ENG) , 2010, DOI: 10.4236/eng.2010.21001
Abstract: A system using microgripper for gluing and adhesive bonding in automatic microassembly was designed, implemented, and tested. The development of system is guided by axiomatic design principle. With a compliant PU microgripper, regional-edge-statistics (RES) algorithm, and PD controller, a visual-servoing system was implemented for gripping micro object, gluing adhesive, and operating adhesive bonding. The RES algorithm estimated and tracked a gripper’s centroid to implement a visual-servoing control in the microassembly operation. The main specifications of the system are: gripping range of 60~80μm, working space of 7mm×5.74mm×15mm, system bandwidth of 15Hz. In the performance test, a copper rod with diameter 60μm was automatically gripped and transported for transferring glue and bonding. The 60μm copper rod was dipped into a glue container and moved, pressed and bonding to a copper rod of 380μm. The amount of binding glue was estimated about 5.7nl.
Mobile Love in China: The Cultural Meaning and Social Implications of Mobile Communications in Romantic Relationships among Young Chinese Adults  [PDF]
Katrin Büchenbacher, Chen-Wei Chang
Advances in Journalism and Communication (AJC) , 2018, DOI: 10.4236/ajc.2018.62004
Abstract: The current study takes a qualitative approach to examining the unique use of mobile communications in romantic relationships among young Chinese adults, a research field few scholars have evinced interest in at this point in time (Lim & Soriano, 2016: p. 4). The overarching question “What is the ‘Chinese-ness’ of the mobile phone user culture of young romantic couples regarding perpetual contact, boundary maintenance, and the connectedness-autonomy tension?” was answered by 15 semi-structured individual interviews. The findings suggest that 1) WeChat messaging was the most prominent mobile media platform used by the respondents to stay in “perpetual contact”, i.e., defined as a continuous conversation through frequent short messages between individuals not physically in the same location (Katz & Aakhus, 2002: p. 2). The interviewees wished to protect their relationship a couple by not disclosing too much or by preventing others from prying too far into it. 3) Respondents resolved the tension between the needs to connect with each other and to remain independent individuals by adopting the former approach. Respondents frequently practiced perpetual contact, supporting the Apparatgeist theory, which views mobile phones as mystical devices that allow constant communication with unseen others, combined with the collective construction of meaning (Katz & Aakhus, 2002). This current study further discusses relevant theoretical and social implications.
Effect of Buerger’s Exercises on Improving Peripheral Circulation: A Systematic Review  [PDF]

Open Journal of Nursing (OJN) , 2015, DOI: 10.4236/ojn.2015.52014
Abstract: The aim of this study was to systematically review the evidence for the effectiveness of Buerger’s exercise on the peripheral circulation or diabetic foot ulceration. A systematic search and 18 electronic databases were conducted. The intervention was predominantly focused on Buerger’s exercise as an outcome. Due to high heterogeneity, data were synthesized in a narrative format rather than by statistical methods. Nine studies that covered 592 participants were selected in the analysis, of which 8 of the 9 found an effect of Buerger’s exercise on peripheral circulation. The positive effects were indicative of improving blood flow, walking ability, reducing necrosis, reducing venous embolism, pain, swelling, cyanosis and the bed-rest times. However, the study design and quality appraisal were limited to Jadad score 2 and the sample size was small. Findings provide some evidence of the beneficial effects of Buerger’s exercises. It was seen as a low cost and low risk physical activity that most diabetic patients could undertake at home. This review highlighted a need for further investigation of standardized procedures of Buerger’s exercises. More high quality studies on the prevention of diabetic foot are required regarding Buerger’s exercises.
