  • As digital technology has advanced in the field of dentistry, the use of computer-aided design/computer-aided manufacturing (CAD/CAM) has brought changes to the stages of dental treatment. The use of CAD/CAM technology in dental restoration offers clinical efficiency and convenience by reducing production time and appointment intervals, while also simplifying the fabrication process to reduce errors. In this case, digital replication and printing of temporary teeth were used to aid a patient with complex medical histories and physical disabilities. The final impression obtained with silicone impression material included information on the vertical dimension, centric relation, and the angle and length of the anterior teeth, which shortened the production time and appointment intervals and increased patient satisfaction. The final restoration was fabricated using milling and monolithic disc techniques, demonstrating appropriate stability, retention, and support, resulting in functional and aesthetic satisfaction.

  • Traditional, complementary, and alternative medicine(CAM) constitutes a major source of health care in developing countries. Its therapies, products and practices are increasing used in industrialized countries, typically by around 50% of the population. However, controls on the provider of CAM services and supply and promotion of complementary medicines are weak in these countries. These trends evoke important public health questions relating to benefits and detriments, safety and quality from medical, financial, and social perspectives. In the western counties, investment in research is increasing, and some guideline is now available for ensuring their quality, efficacy, and safety according to the criteria of evidence-based medicine as legally demanded. National policies and legislation are being developed in many countries and often include partnerships between biomedical and traditional health practitioners. The purposes of the study were to review the policies on CAM, to examine the responses of the government to cope with use of CAM in industrialized countries. Lastly, some implications and recommendation are suggested.

  • As consumer's desire becomes various, agility of mold manufacturing is most important factor for competence of manufacturer. In common works to use commercial CAM system to generate tool path, some decision making process is required to produce optimal result of CAM systems. We propose tool selection procedures to aid the decision making process. The system provides available tool size for machining of design model part of injection mold die by analyzing sliced CAD model of die cavity and core. Also, the tool size information is used to calculate machining time. The system is developed with commercial CAM using API. This module will be used for optimization of tool selection and planning process.

  • In this paper, the Post Process for the manifold complex processing using CAD/CAM Software of two and a half Dimensions(2.5D) has been developed to maximize the application of the manifold manufacturing machine. Many companies are currently making use of high price systems to improve manufacturing process using the multi-axial complex manufacturing machine. In accordance with the requirements, the utilization of CAD/CAM Software for the manifold complex manufacturing machine is earnestly demanded. However, the experts who have experience in manifold manufacturing machine are insufficient. Consequently the outcomes of the Post Process for 2.5D CAD/CAM Systems have been dealt in order to be smoothly operated by those who have basic skills and be understood in process drawings. CNC program functions can be specially used as they are, when drawn up. The Post Process for the original point designation and transformation of coordinates has been developed and applied. The results gave proof of practical manufacturing outcomes.

  • The use of Complementary and Alternative Medicine (CAM) is increasing in Norway. A growing number of nurses choose to offer CAM, and the purpose of the study presented in this article was to examine the reasons for their choices. Fieldwork including interviews with 20 nurses offering CAM was conducted. The results showed that the nurses in general are not satisfied with the public health service. They had four main reasons for their choice to offer CAM: 1. A desire to perform holistic nursing. 2. A tendency to value self-realization. 3. A wish to experience meaning in their work and develop a stronger professional identity. 4. A freedom to mix care and cure. The results of this study are also discussed in view of medicalization.

  • Objectives: This study aimed to determine the knowledge levels and attitudes of School of Health and Vocational School of Health students toward complementary and alternative medicine (CAM). Methods: Three hundred thirty-three (333) students studying at the Mehmet Akif Ersoy University School of Health and the Golhisar Vocational School of Health in Burdur, Turkey, were included in the study. Research data were collected by using a survey method based on the expressed opinions of the participants. Results: Of the participants, 69.7% were female and 97% were single (unmarried). Of cigarette users and those with chronic illnesses, 46.8% and 47.8%, respectively, used CAM. Those using CAM were statistically more likely to be female (P < 0.021), to have higher grades (P < 0.007), to be single (P < 0.005), to be vocational school of health graduates (P < 0.008), and to have fathers at work (P < 0.021). While 9.6% of the students thought CAM to be nonsense, 10.8% thought that the methods of CAM should be tried before consulting a doctor. Conclusion: A majority of the students in the study population were found to use complementary and alternative medicine, but that they lacked information about its methods. As a way to address this, CAM should be included in the curriculum of schools that provide health education, and CAM training programs should be given to healthcare professionals to improve their knowledge of CAM. In Turkey, many more studies should be performed to determine nurses' and doctors' knowledge of and attitudes about CAM methods so that they can give correct guidance to society and take more active responsibility in improving patient safety.

  • Objectives : Cancer patients who are afraid of unpleasant therapy and doubt a perfect cure often seek out traditional Korean medicine or many other kinds of complementary and alterative medicine (CAM) instead. This study was carried out in order to learn the prevalence and kinds of the traditional Korean medicine and CAM to evaluate awareness of and attitude toward it. Methods : 213 patients with gastric cancer who had undergone surgery in the department of gastrointestinal surgery and visited for routine follow-up from November to December of 2004 were included. A questionnaire survey was done by trained interviewers for CAM and demographic information. Results : 96.7% of patients had experience with CAM. The kinds and frequencies of CAM were diet and nutrition 21.0%, folk remedy 21.0%, pharmacological treatment 13.5%, oriental medicine 5.3% and mind-body intervention 1.4%. 56.8% of patients had experienced 2-6 kinds of CAM, 37.4% more than 7. Among diet and nutrition, ginseng (62.9%) was highest, followed by ox leg bone soup (50.8%) and pumpkin (31.5%). Among the folk remedies, elm tree was highest at 46.5%, followed by phellinus linteus (Sang-Whang) at 26.8% and ganoderma lucidum (Young-Gee) 20.7%.satisfaction with CAM was relatively low (43.2%), many patients (78.2%) replied that they would use it continuously. Conclusion : Most patients had experience with many kinds of CAM, but didn't discuss it with medical doctors. If scientific study proves whether or not each kind of CAM is actually effective ondisease, it will help to improve the health of patients and prevent the inappropriate usage and cost.

  • Purpose: This study analyzes the self-efficacy and CAD/CAM practice of dental technology students with the aim of providing data that will be useful for improving CAD/CAM education. Methods: A questionnaire survey on self-efficacy and CAD/CAM practice was given to students who participated in face-to-face classes in the Department of Dental Technology at a college in Daegu and Gyeongsangnam-do. The survey period was two weeks long (June 15, 2020 to July 2, 2020), and 84 students completed the questionnaire. Results: The higher the self-efficacy, the fewer difficulties or mistakes students made in CAD/CAM practice. The most difficult parts of the scanning process were the top and bottom arc operation and the bite match arc insertion. The most difficult part of the design work was the use of (multiple) tools. The difference between the degree of difficulty and the degree of mistakes during the practical course was shown as the margin line setting in the design work. Setting the margin line was not difficult, but the degree of mistakes was nonetheless high. In the CAM process, height control was the most difficult part, but the degree of mistakes did not differ according to students' self-efficacy. Conclusion: Given that higher self-efficacy correlated with fewer difficulties or mistakes in CAD/CAM practice, students should be encouraged to enhance their self-efficacy. This may be done by improving their satisfaction with their major course of study, forming friendly relations with their colleagues, and increasing the ratio of performance rather than observation in CAD/CAM practice.
