  • Twelve dogs weighing less than 10 kg underwent unilateral TTO to stabilize the stifle joint with cranial cruciate ligament rupture. Surgical findings, intra-operative and post-operative complications were recorded. Radiographic examinations were performed for 8 weeks following surgery. Postoperative outcome was evaluated using a visual analogue lameness scoring system. Mean preoperative PTA (the angle created by the intersection of the tibial plateau extrapolation line and the patellar tendon) was 103.8 degrees. Mean tibial wedge angle was 16.6 degrees. Mean postoperative PTA was 92.1 degrees. Intraoperatively, fracture through the caudal tibial cortex occurred in all dogs, through the distal tibial crest cortex in 2 dogs, through the lateral tibial cortex in 2 dogs and through the fibula in 1 dog. Four-week postoperative radiographs demonstrated evidence of progressive bone union at osteotomy site and complete unions were identified at 8 week in 10 dogs. All dogs were healed in 11 weeks. Most of dogs revealed weak lameness in 4 weeks and normal ambulation in 8 weeks postoperatively except for only one dog returned in 11 weeks. Despite frequent minor complication, it appears that the TTO is an alternative procedure for management of cranial cruciate ligament rupture in small breed dogs.

  • When the driver riding in a bicycle goes on board, the load of driver is shown differently according to the position loaded on the frame of bicycle. The load is applied most at the joint of bike frame and the load at the mid-part of frame is applied least than the other parts. So, the weight of frame is decreased as the part not applied with a lot of load is manufactured into the thin thickness. As the part applied with high load is manufactured into the thick thickness, it can be endured through this load. The configurations of general frame, double butted and triple butted were modelled by using CATIA program. The durabilities of each model due to the load of passenger were investigated by carrying the structural and fatigue analyses. As this study result investigated with the analysis program of ANSYS, the deformation of general frame happened most and that of triple butted became least. These simulation analysis data are intended to be used to design the actual bicycle frame in the most efficient way at design and manufacture.

  • The flexors and extensors of the knee joint are essential for maintaining body stability. The purpose of this study was to investigate the correlation between the isokinetic parameters of the knee flexor and extensor muscles and the function of the lower extremity muscles. Twenty-two healthy adults participated in this study. The time to peak torque (TTP), acceleration time (AT), and peak torque (PT) of the knee flexor and extensor muscles were measured. A 20m sprint, Sargent jump, one leg hop test, and side shuffle were measured to evaluate lower extremity function. The correlation between each variable was analyzed using Pearson correlation coefficient. PT of the knee flexor showed a significant correlation with single leg hops and 6M hops in a single leg. PT of knee extensors was found to be significantly correlated with Sargent jumps and triple hops. Based on the results of this study, we suggest that the strength of the knee flexor and extensor muscles has the potential to be used to predict lower extremity function.

  • The focus of this investigation is to evaluate the effect of joining parameter on the microstructure and mechanical properties of welds produced by friction stir lap welding. The dissimilar Al alloys, KS5J32 and AA6K31, were joined by friction stir lap welding technique under several welding conditions, and KS5J32 alloy was placed on the top of AA6K31 alloy. The tool rotation speeds were 1000, 1250, and 1500rpm, and the welding speeds were 100, 300, 500, 700mm/min, respectively. The results showed that two shapes of nugget, such as onion ring and irregular vortex type, were observed with various revolutionary pitch. In all welding conditions, fracture occurred at the soften region of bottom sheet(AA6K31) and the strengths were 64~78% of those of base metal. Fractured positions were classified into three types : HAZ, triple point, void depending on the revolutionary pitch. The actual thickness of specimen at the fractured location was decreased with decreasing heat input. A linear relationship exists between the effective thickness of fractured position and peak load.

  • Benign osteoblastoma, a rare tumor which forms osteoid and woven bone, represents 3% of benign and 1% of all primary bone tumors. It can involve anywhere in the axial skeleton, which is most common in the spine (34%). But the lesion of the calcaneus is extremely rare. The ratio of males to females is 2:1, with 80 percent of the patients being under thirty years of age. Pain is the most common symptom and rarely pathologic fracture. Osteoblastoma is a benign tumor but has a high recurrence rate after intracapsular malignant change. Therefore, choice of surgical procedure is the 'enbloc' resection. Authors have experienced a case of osteoblastoma developed in calcaneus. The treatment was wide resection and triple arthrodesis. We have reported here the case in which osteoblastoma occured in calcaneus of the right foot.

  • The research aims to explore the links among corporate governance, corporate social responsibility, and earnings management, considering vital roles of each component in Vietnam. There were 500 questionnaires provided to the targeted enterprises, where there were 150 enterprises in Ho Chi Minh Stock Exchange, 150 enterprises in Hanoi Stock Exchange, and 200 enterprises in the unlisted public company market. Of the distributed questionnaires, only 289 replies offered needed information for analyses. The data derived from these firms was based on their annual or sustainability statements that were retrieved from the websites. This research used a six-year rolling window to calculate earnings management. To compute that variable, lagged year information was included, so the data from 2011 to 2017 was needed to collect. The empirical results show that corporate governance mechanism is a significant moderation in the positive link between good corporate social responsibility and earnings management. Furthermore, corporate social responsibility and earnings management also play mediating roles in the associations among corporate governance, corporate social responsibility, and earnings management. This project recommends that corporate governance mechanism is an essential driver of the managerial behaviors in social responsibility and ethical accounting practices, which are in turn mediators in the joint research model.

  • In this paper we propose a content-based image retrieval method that can search large image databases efficiently by color, texture, and shape content. Quantized RGB histograms and the dominant triple (hue, saturation, and value), which are extracted from quantized HSV joint histogram in the local image region, are used for representing global/local color information in the image. Entropy and maximum entry from co-occurrence matrices are used for texture information and edge angle histogram is used for representing shape information. Relevance feedback approach, which has coupled proposed features, is used for obtaining better retrieval accuracy. Simulation results illustrate the above method provides 77.5 percent precision rate without relevance feedback and increased precision rate using relevance feedback for overall queries. We also present a new indexing method that supports fast retrieval in large image databases. Tree structures constructed by k-means algorithm, along with the idea of triangle inequality, eliminate candidate images for similarity calculation between query image and each database image. We find that the proposed method reduces calculation up to average 92.9 percent of the images from direct comparison.

  • Colloid Formation and Migration (CFM) project is being carried out within the Grimsel Test Site (GTS) Phase Ⅵ. Since 2008, the Korea Atomic Energy Research Institute (KAERI) has joined CFM to investigate the behavior of colloid-facilitated radionuclide transport in a generic Underground Research Laboratory (URL). The CFM project includes a long-term in-situ test (LIT) and an in-rock bentonite erosion test (i-BET) to assess the in-situ colloid-facilitated radionuclide transport through the bentonite erosion in the natural flow field. In the LIT experiment, radionuclide-containing compacted bentonite was equipped with a triple-packer system and then positioned at the borehole in the shear zone. It was observed that colloid transport was limited owing to the low swelling pressure and low hydraulic conductivity. Therefore, a postmortem analysis is being conducted to estimate the partial migration and diffusion of radionuclides. The i-BET experiment, that focuses more on bentonite erosion, was newly designed to assess colloid formation in another flow field. The i-BET experiment started with the placement of compacted bentonite rings in the double-packer system, and the hydraulic parameters and bentonite erosion have been monitored since December 2018.

  • Various innovation theories, such as innovation system, innovation cluster, triple helix model, are different in their focus. However they all emphasize the interaction between innovation actors in order to generate, diffuse, and appropriate technological innovations successfully. This study analyzes how the interaction of innovation actors in Daedeok Innopolis has been changed since the introduction of innovation cluster policy like the designation of Daedeok Innopolis. Based on the analysis of survey data, Innopolis statistics, and patent joint-application data, we come to the conclusions that the Daedeok Innopolis has characteristics of multi-level governance structure, in which innovation cluster, i.e. Daedeok Innopolis, regional innovation system, and national innovation system directly overlap under the framework of innovation system. In addition, from the perspectives of triple helix model, we are able to verify that the inter-domain interactions between innovation actors, such as tri-lateral network, have been constantly increased in the Daedeok Innopolis. Based on our analysis, we identify some policy suggestions in order to strengthen the competitiveness of the Daedeok Innopolis as well as other innovation clusters in Korea. First, the network activities between innovation actors within innovation cluster should be strengthened based on the geographical accessibility. Second, private intermediate organizations should be established and their roles should be extended. Third, the entrepreneurial activities of universities within innovation cluster should be strengthened. In other words, the roles of universities within the Innopolis should be activated. Finally, the government should provide relevant policy supports to activate the interactions between innovation actors within innovation cluster.
