Backgrounds : The market of Complementary Alternative Medicine(CAM) in the United State(U.S.) accounts for a large proportion of the global CAM market and has a high growth rate. The recent introduction of Obama Care has brought the change in the health insurance system for CAM, and we need to analyze it for its implication to Korean system. Objectives : The purpose of this study is to investigate the current status of acupuncture and chiropractic health insurance in the U.S., and to draw implications for expanding the health insurance coverage for Korean traditional medicine through the comparison between the U.S. and Korean health insurance systems. Methods : We examined the data through the literature search and from the websites of both U.S. government departments and related organizations for the health insurance policy. Based on the collected data, we analyzed its CAM health insurance system in Korea. Results : The acupuncture covered by public health insurance in the U.S. has a limit in the number of treatments and a range of applied diseases compared with Korea. In addition, the practice of acupuncture is not subdivided. However, the chiropractic in the U.S. which also has a limited number of coverage and only three categories of practices are similar to that of Korea. Conclusions : Although the use of CAM by public health insurance is not active in the U.S., but the organizations such as Veterans Health Administration in Vermont is already discussing the use of acupuncture to solve the problem of opioid overuse. Thus Korea also needs to discuss to promote the expansion of the insurance system for CAM.

The increasing use of complementary and alternative medicine(CAM) in Korea as well as in U.S.A. and Europe seems to lead to a growing integration of CAM with conventional medicine. By using conventional mainstream medicine with CAM(integrative medicine) proved in efficacy and safety, integrative medicine seeks to treat the whole person, to assist the innate healing properties of each person and to promote health and wellness as well as the prevention of diseases. Also in pediatric diseases, especially for cancer patients, integrative medicine serves as an interdisciplinary, comprehensive, and children-centered care which results in more effective care by synergistically combining therapies. But the research to prove the efficacy and safety of CAM and the education for CAM in the medical school should proceed before applying them to patients.

Recently incremental sheet metal forming (ISF) has used widely in making prototypes and small-volume products in automotive industry etc. We apply the ISF to make a 1/4 sized automobile body-in-white. First, ISF tests for rectangular shaped cup have been performed to clarify the formability denoting the relationship between the component wall angle and maximum cup height of safe forming. Next, a CAD model for the automobile was designed and segmented into several components in order to accommodate the working space of the CNC machine we adopted and the formability of the sheet metal. Then, a CAM software was employed to generate the tool path for manufacturing wooden dies and all the small parts. Finally, the different parts were joined into a single component by laser welding after the ISF process. By using the ISF we successfully produced the 1/4 sized automobile body-in-white.

The demand for complementary and alternative medicine (CAM) is increasing worldwide. High-technology medicine is not always effective and is often accompanied by neglected self-care and high cost. Also, conventional medicine has become dependent on expensive technological solutions to health problems. Integrated medicine is not simply a synonym for complementary medicine. It involves the understanding of the interaction of the mind, body, and spirit and how to interpret this relationship in the dynamics of health and disease. Integrative medicine shifts the orientation of the medical practice from a disease-based approach to a healing-based approach. In South Korea, CAM education was first provided 20 years ago, and integrative medicine is becoming part of the current mainstream medicine. Increasing numbers of fellowships in integrative medicine are being offered in many academic health centers in the U.S. Also, it has emerged as a potential solution to the American healthcare crisis and chronic diseases, which are bankrupting the economy. It provides care that is patient-centered, healing-oriented, emphasizes the therapeutic relationship, and uses therapeutic approaches originating from conventional and alternative medicine.

In recent years, RGM(roller gear mechanism) systems, wherein one of the gears of a meshing gear pair is replaced with pins or rollers, have been reintroduced, which is a consequence of, and therefore a reflection of, the rapid advances made in manufacturing technology. Three RTG(roller track gear) systems for arbitrary path transportation (e.g., L-, O-, U-, and S-shaped tracks) were constructed using two out of three RGM systems, namely, the CRP(cam rack pinion), CRG(cam ring gear), and RPG(roller pinion gear) systems, and are introduced in this paper. We also present three ways to prevent the intersection and non-contact phenomena at the teeth in the vicinity of the conversion point between two joined RGM systems.

본 연구에서는 다양한 두께와 색조를 가진 레진 -나노세라믹 CAD-CAM block(RNB)의 시편을 이용하여 광중합 시 시편을 투과하는 광자의 수와 시편을 통과하는 빛의 양에 영향을 미칠 수 있는 반투명도 지수를 측정하고, 시편 하방의 이원중합 레진시멘트의 미세경도 측정을 통해 그 중합적 특성을 파악하였다. Lava Ultimate (3M/ESPE, St. Paul, MN, USA) 세라믹 시편을 A1, A2, A3색조 (HT (high translucency)와 LT (low translucency))로 각각 1, 2, 3, 4 mm 두께로 제작하였다 (n = 3). Photodiode detector (M1420, EG&G PARC, Princeton, NJ, U.S.A.)를 통해 시편을 통과하는 광자의 수를 측정하였고 spectrophotometer (SpectroPro-500, Acton Research, Acton, MA, U.S.A.)를 이용하여 시편의 반투명도 지수를 측정하였다. Stainless steel mold (6 mm 직경, 1 mm 두께)를 제작하여 이원중합 레진시멘트(Rely X ARC, 3M/ESPE, St. Paul, MN, USA)를 제조사의 지시대로 조작하여 적용 후 Mylar strip를 얹은 뒤 주입된 레진시멘트가 완전히 덮일 수 있도록 각 실험군의 시편을 위치시키고 광조사기로 40초간 광중합 하였다. 이후 24시간 동안 $37^{\circ}C$에 보관 후 미세경도를 측정하였다. 광자의 수는 HT, LT군에서 모두 세라믹 시편의 두께가 증가함에 따라 유의하게 감소하였고, A1 군이 A2군과 A3군에 비해 유의하게 적은 감소를 보였다 (p<0.05). 반투명도 지수는 HT, LT 그룹에서 시편의 두께가 증가함에 따라 유의하게 감소하였고 A1군이 A2군과 A3군에 비해 높은 값을 나타냈다 (p<0.05). HT, LT그룹 각각 두께가 증가함에 따라, 색조가 증가함에 따라 미세경도는 감소하였으며, 1 mm군과 4 mm군, 그리고 A1군과 A3군에서는 통계적으로 유의하게 감소하였다 (p<0.05).

Background and aim: Pancreatic cancer is the fourth leading cause of cancer-related death worldwide, with an overall 5-year survival of <5% mainly due to presence of advanced disease at time of diagnosis. Therefore development of valid biomarkers to diagnose pancreatic cancer in early stages is an urgent need. This study concerned the sensitivity and specificity of serum ICAM 1 versus CA 19-9 in differentiation between pancreatic cancer and healthy subjects and acohort of patients with chronic pancreatitis with a focus on assessing validity in diagnosis of early stages of pancreatic cancer. Methods: A cohort of 50 patients with histologically diagnosed pancreatic tumors, 27 patients with chronic pancreatitis, and 35 healthy controls were enrolled. Serum samples for measurement of CA19-9 and I-CAM 1 were obtained from all groups and analyzed for significance regarding diagnosis and disease stage. Results: At a cut off value of (878.5 u/ml) I-CAM 1 had 82% and 82.26% sensitivity and specificity for differentiation between cancer and non-cancer cases, with higher sensitivity and specificity than CA19-9 at different cut offs (CA19-9 sensitivity and specificity ranged from 64-80% and 56.4 - 61.2% respectively). The AUC was 0.851 for I-CAM and 0.754 for CA19-9. Neither of the markers demonstrated significance for distinguishing between early and late cancer stages. Conclusion: ICAM 1 is a useful marker in differentiation between malignant and benign pancreatic conditions, and superior to CA19-9 in this regard. However, neither of the markers can be recommended for use in differentiation between early and late stage pancreatic cancers.
