Die-casting burr due to casting process is removed by post-process for assembly and quality control of product. Though robot has been widely used for deburring job before, CNC exclusive machine is currently developed f3r high power, high speed machining and quick tool change. Deburring tool path with complex 3D curve type is defined to make out deburring NC program. But there is no efficient method to define it currently used methods with teaching probe on machine. In this study the efficient method to make out deburring NC program is developed. 5-axis digitizing machine is used to receive data of deburring path. And the post processor for NC program generation is developed in consideration of the machining conditions. The developed system is not dependent on the skill of operator and has the advantage to maintain the flexibility of job to modify NC program due to the wear of tool and aging of the die casting.

The purpose of this study was to examine whether a gratitude training program for preservice dental hygienists affects their gratitude disposition, self-esteem, and happiness. Dental hygiene students were recruited from a college in D and administered a pretest. The 76 selected participants were primarily those who had never written a gratitude journal. Participants were then randomly divided into an experimental group and a control group. Three participants failed to complete the program, leaving 73 subjects in the final analysis. Data were analyzed using the ${\chi}^2$ test, independent sample t-test, and analysis of covariance. The mean gratitude disposition score improved from $31.11{\pm}5.55$ in the pretest to $34.41{\pm}4.38$ in the posttest in the experimental group and from $31.44{\pm}4.41$ to $32.06{\pm}4.63$ in the control group. The mean self-esteem score improved from $31.22{\pm}4.03$ to $33.16{\pm}3.44$ in the experimental group and from $30.53{\pm}4.42$ to $30.97{\pm}3.80$ in the control group. The mean happiness score improved from $19.54{\pm}2.64$ to $21.78{\pm}2.43$ in the experimental group and from $19.64{\pm}3.32$ to $20.08{\pm}2.91$ in the control group. All of the participants improved their gratitude disposition, self-esteem, and happiness scores while participating in the gratitude training program, and it is expected that if such positive emotions can be sustained, they will naturally acquire the basic requirements of dental hygienists and build a better vocational consciousness and a higher sense of duty, as well as have a further positive effect on the quality of dental medical service. Further studies should be conducted to propose a concrete plan to expand and operate this gratitude training program more effectively.

This study examined the effects of a physical therapy program on quality of life (QOL), and neck and shoulder disability in head and neck cancer patients. The program included neck and shoulder range of motion (ROM) exercises, massage, progressive strengthening exercises, and stretching exercises. Sixteen patients who were assigned to an experimental group performed physical therapy for 40 minutes three times a week for eight weeks. Fifteen other patients were assigned to a control group who did not performed the physical therapy program. The European organization for research and treatment of cancer (EORTC QLQ-C30) and head and neck (EORTC QLQ-H&N) instruments, and the Neck Disability Index (NDI) were assessed before and after the rehabilitation program. The 40-minute program consisted of a 10-minute ROM exercise for the neck and shoulder, a 10-minute massage and 15-minute of progressive resistance exercises, followed by a five-minute stretching exercises. Statistically significant differences were noted for changes in global health, physical function in the EORTC QLQ-C30 and cancer related symptoms in the EORTC QLQ-H&N35 (p<.05). The NDI also showed significant differences (p<.05). Physical therapy may therefore benefit the physical aspects and QOL and improve neck and shoulder disability in patients with head and neck cancer.

Purpose: The purpose of this study was to examine the effects of self-efficacy promotion programs on self-efficacy, self-care behavior, and quality of life in breast cancer patients receiving radiation therapy. Methods: This study was conducted from November 1, 2009 to December 10, 2010. A total of 39 breast cancer patients, who received radiotherapy in a University hospital located in city B, participated in the study and were divided into two groups (experimental group 17 and control group 22). The data were analyzed with the ${\chi}^2$-test and ANCOVA using the SPSS/Win 17.0 program. Results: Self-efficacy promotion programs aimed at self-management were effective in enhancing concrete self-efficacy but not effective in promoting general self-efficacy, self-care behavior, and quality of life among breast cancer patients who have received radiotherapy. Conclusion: Organizing a support group for the breast cancer patients seems to be highly necessary to help themselves obtain higher level of specific self-efficacy, self-care behavior, and quality of life in general. It will also be beneficial for the breast cancer patients to understand their unique situations and improve their health problems for themselves.

The role of radiology department has been greatly increased in the past few years as the technology in the medical imaging devices improved and the introduction of PACS (Picture Archiving and Communications System) to the conventional film-based diagnostic structure is a truly remarkable factor to the medical history. In addition, the value of using digital information in medical imaging is highly expected to grow as the technology over the computer and the network improves. However, the current medical practice, using PACS is somewhat limited compared to the film-based conventional one due to a poor image quality. The image quality is the most important and inevitable factor in the PACS environment and it is one of the most necessary steps to more wide practice of digital imaging. The existing image quality control tools are limited in controlling images produced from the medical modalities, because they cannot display the real image changing status. Thus, the image quality is distorted and the ability to diagnosis becomes hindered compared to the one of the film-based practice. In addition, the workflow of the radiologist greatly increases; as every doctor has to perform his or her own image quality control every time they view images produced from the medical modalities. To resolve these kinds of problems and enhance current medical practice under the PACS environment, we have developed a program to display a better image quality by using the ROI optical density of the existing gray level values. When the LUT is used properly, small detailed regions, which cannot be seen by using the existing image quality controls are easily displayed and thus, greatly improves digital medical practice. The purpose of this study is to provide an easier medical practice to physicians, by applying the technology of converting the H-D curves of the analog film screen to the digital imaging technology and to preset image quality control values to each exposed body part, modality and group of physicians for a better and easier medical practice. We have asked to 5 well known professional physicians to compare image quality of the same set of exam by using the two different methods: existing image quality control and the LUT technology. As the result, the LUT technology was enormously favored over the existing image quality control method. All the physicians have pointed out the far more superiority of the LUT over the existing image quality control method and highly praised its ability to display small detailed regions, which cannot be displayed by existing image quality control tools. Two physicians expressed the necessity of presetting the LUT values for each exposed body part. Overall, the LUT technology yielded a great interest among the physicians and highly praised for its ability to overcome currently embedded problems of PACS. We strongly believe that the LUT technology can enhance the current medical practice and open a new beginning in the future medical imaging.
