Ontology-based Patent Licensing and Litigation Strategic Knowledge System for the Light Emitting Diode Industry
Amy J.C. Trappey,Yu-Hui Wang,Charles V. Trappey,Chun-Yi Wu
International Journal of Automation and Smart Technology , 2013, DOI: 10.5875/ausmt.v3i3.180
Abstract: This research studies the patents, intellectual properties and licensing landscape of the Light Emitting Diode (LED) industry. The ontology of LED technology is described and defined as four major sub-technology domains. The finding provides LED companies with consistent knowledge of their own and their competitors patents and intellectual property rights (IPR) ownership. Major LED companies often use their IPRs to gain and protect their market competitiveness, to form alliances, and to create patent licensing or cross-licensing strategies. Newly established LED technology companies competing with global industry leaders face many challenges unaddressed in the research literature. This research focuses on the empirical and quantitative analysis of historical IP and patent related conduct in relation to corporate strategy. Based on the heuristic rules derived from historical conduct, the research establishes a standardized analytical procedure to use in the evaluation of patent licensing and litigation. The results help researchers effectively and consistently analyze their technical capabilities, evaluate their patent licensing strategies, and review litigation in view of the LED-related IP and patent marketplace.
Ipsilateral Femoral Neck and Shaft Fractures Treated with Russell-Taylor Reconstruction Intramedullary Nails
Hsuan-Kai Kao,Chi-Chuan Wu,Po-Cheng Lee,Chun-Yi Su
Chang Gung Medical Journal , 2006,
Abstract: Background: Ipsilateral femoral neck and shaft fractures are rare injuries and the treatmentis complicated and versatile. No single device has been considered absolutelysuperior to others.Methods: Fifteen combined fractures in 15 patients were treated with Russell-Taylorreconstruction intramedullary nails (recon nails). Twelve surgeries were performedwithin 24 hours of trauma and the other 3 were delayed for 4-7 daysdue to associated life-threatening injuries. Postoperatively, protected weightbearing was permitted as early as possible.Results: The median operating time was 250 minutes (range 125-430 min) and medianblood loss was 300 ml (range 100-600 ml). Thirteen patients were followed-up for a median of 22 months (range 13-45 months). The union ratesfor neck and shaft fractures were 84.6% and 69.2% respectively. The medianunion times were 3.0 months for neck fractures and 8.5 months for shaftfractures.Conclusions: Recon nails are alternative acceptable devices to treat combined fractures.However, the stability of neck fixation may be insufficient and restriction ofvigorous activity is suggested to avoid fixation failure.
Indirect Reduction with Sliding Compression Screw Stabilization for Subtrochanteric Fractures
Yu-Tun Hsu,Chi-Chuan Wu,Chun-Yi Su,Kuo-Fun Fan
Chang Gung Medical Journal , 2006,
Abstract: Background: Subtrochanteric fractures possess unique characteristics, and no single deviceused in their treatment is considered absolutely superior to others. Use ofsliding compression screws (SCSs) is technically simple. The feasibility ofSCS stabilization was evaluated using indirect reduction of fracture fragments.Methods: One hundred and thirty-one acute subtrochanteric fractures without extensiveshaft involvement were treated using this technique, and they were classifiedinto 4 groups to evaluate the success rate. After the lag screw was insertedinto the femoral head, the side plate was applied onto the distal fragmentwithout exploring the fracture site. At least 4 cortical screws were used tostabilize the distal fragment. Postoperatively, ambulation with protectedweight bearing was encouraged at as early a time as was possible.Results: One hundred and thirteen fractures were followed-up for 12~38 (mean, 22)months. The union rate was 94.7% (107/113), and the time period until unionoccurred was 2.5~8 (mean, 3.8) months. No statistical difference was notedamong the individual groups. Complications included 6 nonunions (5.3%),which were associated with infection in 1 case (0.9%) and implant failure in2 cases (1.8%).Conclusions: Compared to other techniques, indirect reduction with SCS stabilization is afeasible method for treating acute subtrochanteric fractures. However,because plate insertion normally requires a large dissecting wound and biomechanicallythe tension band principle might not be applicable, there maybe greatly increased complications with extensively comminuted fractures.Accordingly, if this technique is used for carefully selected fractures, a highsuccess rate can be expected.
Surgical Treatment of Acute Complete Acromioclavicular Dislocation: Comparison of Coracoclavicular Screw Fixation Supplemented with Tension Band Wiring or Ligament Transfer
Wei-Ching Lin,Chi-Chuan Wu,Chun-Yi Su,Kuo-Feng Fan
Chang Gung Medical Journal , 2006,
Abstract: Background: Treatment of acute complete acromioclavicular (AC) dislocation is still controversial.Both non-surgical and surgical methods have been reported withsimilar results. In addition, once surgical treatment is chosen, a satisfactorysurgical technique has not been developed yet.Methods: Sixty consecutive patients who sustained 60 acute complete AC dislocationswere treated using coracoclavicular (CC) screw fixation supplemented withtension band wiring for the AC joint (n = 30) or coracoacromial (CA) ligamentreconstruction (n = 30), respectively. The operating times, functionaloutcomes, and complications were compared.Results: Twenty-nine patients with tension band wiring (group 1) and 27 patients withCA ligament reconstruction (group 2) were followed-up for 12-47 (mean,23.6) months. The operating time was 34-57 (mean, 46.3) minutes in group1verse 52-93 (mean, 83.4) minutes in group 2 (p < 0.001). The percentage ofsatisfactory outcomes was 86.2% in group 1 verse 88.9% in group 2 (p =0.30). Loss of reduction of the AC joint was 13.8 % (4/29) in group 1 verse3.7% in group 2 (1/27, p = 0.17). Patients who received tension band wiringtreatment had a higher rate of unsatisfactory outcomes when loss of reductionof the AC joint occurred (p = 0.01).Conclusions: Once surgical methods are chosen in patients with acute complete AC dislocation,CC screw fixation supplemented with tension band wiring for the ACjoint or CA ligament reconstruction achieved similar satisfactory rates.However, patients who received the former had relatively shorter operatingtimes.

Chang Gung Medical Journal , 2006,
Abstract: Background: Exchange nailing is reported to have a high success rate for aseptic tibialnonunions. However, sample sizes in all series in the literature were small,and the influence of a concomitant fibulotomy was not evaluated.Methods: Fifty-four aseptic tibial shaft nonunions for 1.2~4.3 (mean, 2.4) years weretreated with exchange nailing. Indications for this technique included anaseptic nonunion of the tibial shaft with an inserted intramedullary nail and <2 cm of shortening. A fibulotomy was performed in a nonunion with poorshaft alignment, which concomitantly required manipulation to correct. Thesuccess rate of exchange nailing was determined, and whether a concomitantfibulotomy affected the success rate was evaluated.Results: Forty-seven nonunions were followed-up for 1.1~6.9 (mean, 3.8) years, andall nonunions healed. The union rate was 100% (47/47), and the averageperiod required to achieve union was 4.7 (3.0~7.5) months. The averageunion periods between the fibulotomy and non-fibulotomy groups did notstatistically differ (4.6 vs. 4.8 months, p = 0.61). There were no significantcomplications in either group.Conclusions: Exchange nailing is an excellent technique to treat aseptic nonunions of thetibia. It can be considered the treatment of choice for all indicated cases. Aconcomitant fibulotomy has minimal influence on the success rate. It can beperformed when the shaft alignment needs correction.
Between Dependency and Autonomy – Taiwanese Entrepreneurs and Local Chinese Governments
Chun-yi Lee
Journal of Current Chinese Affairs , 2010,
Abstract: This paper focuses on the changing interaction between Taiwanese entrepreneurs and local Chinese governments. Through the analysis of this changing process, it can be seen that Taiwanese businesses are a special “asset” of Chinese governments. The main argument of this paper is that both central and local governments in China have strategic considerations in respect of Taiwanese businesses. The Chinese central government values Taiwanese businesses because more Taiwanese investment in China strengthens the Beijing government in negotiations with the Taibei government. Nevertheless, since the Kuomintang (KMT) (Guomindang) regained power in 2008, the strategic value of Taiwanese businesses in the cross-Strait relationship seems to have decreased. The central government has created a profitable macro-environment enabling local officials to give a warm welcome to Taiwanese businesses. Chinese local governments value Taiwanese businessmen not only because of the central government’s deliberate policy but also because they are pursuing their own self-interest. This paper firstly focuses on the changing interaction between Taiwanese businesses and Chinese local governments. It then further analyses the different but complementary interests of both central and local governments in China in relation to Taiwanese investors.
Is the Impact of a Support System on Job Satisfaction Different between Employees in Taiwan and Mainland China?  [PDF]

Chinese Studies (ChnStd) , 2019, DOI: 10.4236/chnstd.2019.83005
Abstract: From the perspective of social exchange theory (SET), the study examines a mediated model linking perceived human resource management (HRM) practices and perceived supervisor support (PSS) with work engagement and job satisfaction. This study also empirically investigates the invariance of sub-groups among 1362 full-time employees recruited from Taiwan and Mainland China. The results show that work engagement strongly was linked to job satisfaction and mediated the relationship between perceived HRM practices and PSS. In addition, no significant of different groups is evident in the structural relations among the employees in Taiwan and Mainland China. The findings suggest that the enactment of positive behavioral outcomes because of engagement and job satisfaction largely depends on organizational support, including HRM practices and supervisor encouragement.

Technology and Investment (TI) , 2018, DOI: 10.4236/ti.2018.93011
Abstract: Background: Regulation requires periodic reconfirmation of the number of radioactive sources in Gamma Knife (GK). To comply with regulations, the total dose output (TDO) method, originally designed to verify amount of radiation received by patients, was adopted as a tool for source security. However, we suspect the TDO method may be unreliable in detecting small numbers of missing sources given that a 2% margin of error is allowed. We propose an alternate method using Gafchromic films to identify number of sources present. Method: To test the efficacy of the TDO method, we simulated real-life source loss by plugging up to 5 sources. TDO after plugging 0, 1, 2, 3, 4, and 5 sources were measured using GK 4C. Percentage change for each additional source plugged was computed. We then proceeded to test the film method. For GK 4C, 2 Gafchromic RTQA2 single sided films measuring 10 × 10 inch were first halved to 5 × 10 inch films. Four 5 × 10 inch films were then adhered to the inner surface of the 18
Ultraviolet C Irradiation Induces Different Expression of Cyclooxygenase 2 in NIH 3T3 Cells and A431 Cells: The Roles of COX-2 Are Different in Various Cell Lines

International Journal of Molecular Sciences , 2012, DOI: 10.3390/ijms13044351
Abstract: Ultraviolet C (UVC) is a DNA damage inducer, and 20 J/m 2 of UVC irradiation caused cell growth inhibition and induced cell death after exposure for 24–36 h. The growth of NIH 3T3 cells was significantly suppressed at 24 h after UVC irradiation whereas the proliferation of A431 cells was inhibited until 36 h after UVC irradiation. UVC irradiation increased COX-2 expression and such up-regulation reached a maximum during 3–6 h in NIH 3T3 cells. In contrast, UVC-induced COX-2 reached a maximum after 24–36 h in A431 cells. Measuring prostaglandin E2 (PGE2) level showed a biphasic profile that PGE2 release was rapidly elevated in 1–12 h after UVC irradiation and increased again at 24 h in both cell lines. Treatment with the selective COX-2 inhibitor, SC-791, during maximum expression of COX-2 induction, attenuated the UVC induced-growth inhibition in NIH 3T3 cells. In contrast, SC-791 treatment after UVC irradiation enhanced death of A431 cells. These data showed that the patterns of UVC-induced PGE2 secretion from NIH 3T3 cells and A431 cells were similar despite the differential profile in UVC-induced COX-2 up-regulation. Besides, COX-2 might play different roles in cellular response to UVC irradiation in various cell lines.
