Designing a production and equipment investment plan for semiconductors, many variables must be taken into account. However, depending on these variables could bring many changes to the plans, and the end result is hard to predict. Because it's hard to predict the end result, it's never easy to make a standard production plan. So, the goal of this project is to design a production plan based on past marketing patterns to satisfyall the variables and come up with a reasonable thesis on a standardized process.

The nitric oxide (NO) participates in various therapeutic process in vivo such as anti-restenosis, wound healing and antibacterial activity. Therefore, diverse NO delivery platforms have been reported, however, there have been continuous opinions which point out the question about the biocompatibility of the materials and NO capacity. Herein, we exploit bio-inspired polydopamine (pDA) to develop biocompatible nanocapsule-based NO delivery platform. pDA shows biocompatibility in vivo and includes a lot of secondary amine groups for conjugating the diazeniumdiolates, one of the NO-releasing moiety. Moreover, the capsule platform was expected to provide the cavity for keeping various bioactive molecules for further study. Based on these rational designs, the pDA-NO capsule was developed. The successful fabrication of pDA-NO capsule was confirmed and its NO-releasing properties and biomedical potential were evaluated.

Objective: To determine the effects on the lumbar stability caused by various thoracic exercise programs, the extent of spinal posture correction and the increase in thoracic mobility to the extension direction. Method: Exercise programs, which can increase the thoracic mobility to the extension direction, were applied to the exercise group. The control subjects were trained for the correct posture according to ergonomic principles by exercise at home and at the clinic. Both groups had three sessions of exercise program per week for 8 weeks. Results: A comparison of the various parameters in the exercise group before and after exercise showed that the VAS, thoracic kyphosis and lumbar mobility decreasedsignificantly (p<0.05), and the thoracic mobility in the extension direction, chest expansion, maximal elevation of the arms and spinal length increased significantly (p<0.05). In addition, the thoracic kyphosis and lumbar mobility increased significantly (p<0.05), and thoracic mobility in the extension direction, chest expansion, maximum elevation of the arms and the spinal length decreased significantly (p<0.05), but the VAS did not show a significant difference. Conclusion: A thoracic exercise program, which can correct the posture, improve the functional restrictions of the thoracic spine and reduce the lumbar mobility, is very important.
