Objectives This study aims to review and summarize existing evidence on moxibustion treatment for cancer patients. Methods Literature published until May 2015 in international journals were searched on PubMed, CAJ (CNKI-Medicine), NDSL (National discovery for science leaders), Sage Journal, ScienceDirect, Taylor&Francis Online (HSS), and Wiley Interscience (including Blackwell); and articles in Korean journals were searched on Korean Studies Information Service System (KISS), DBPIA, E-Article, KSI e-book, New article, Korea Institute of Science and Technology Information (KISTI), and Kyobo scholar. Results We analyzed 65 relevant studies. The number of studies conducted annually has increased and most are conducted in Korea and China. Moxibustion decreases the side effects of palliative treatment, thereby synergizing with anticancer treatment; it also improves the immune system, reduces tumor factors, and relieves symptoms. The mechanism of moxibustion is multi-fold: thermo, chemo, aero and kinetic. Only the kinetic effect is not significant. It also needs a complement to moxibustion because of harmful smoke. Conclusions Thus, the effect and mechanism of moxibustion in cancer patients was reviewed. There is an unmet need to develop a model of moxibustion and test it based on Korean medicine.

Quality of life(QoL) of older cancer patients have not gained enough attention from researchers even when cancer is the number one cause of death of Korean elderly. Therefore, this study aims at understanding the QoL of older cancer patients and factors related to it, applying Taylor(2012)'s Stress-Coping Process model, and by comparing with older chronic disease patients and middle-aged cancer patients. Results indicated that physical health QoL of older cancer patients was the worst and their mental health QoL was similar with middle aged cancer patients. Multi-group analysis of Structural Equation Modeling indicated that the relation between QoL and the stress coping resources was not statistically different from older cancer patients and older chronic disease group, as well older cancer patients and middle-aged cancer patients. Implications of results to improve the QoL of older cancer patients are discussed.

Most metals are polycrystalline material whose deformation is dominated by the slip system. During the deformation process, orientation of slip systems is rearranged with preferred orientations, leading to deformation-induced crystallographic texture which is called deformation texture. Depending on the texture development, the property of material can be changed. The rate-independent crystal plasticity which is based on the Schmid law as a yield function causes a non-uniqueness in the choice of active slip systems. In this work, to avoid the slip system ambiguity problem, rate-independent crystal plasticity model based on the smooth yield surface with rounded-off corners is adopted. In order to simulate the polycrystalline material under plastic deformation, we employ the Taylor model of polycrystal behavior that all the grains are assumed to be subjected to the macroscopic velocity gradient. Rigid-plastic finite element program based on this rate-independent crystal plasticity is developed to predict the grain-level deformation behavior of FCC metals during metal forming processes. In the finite element calculation, one integration point is considered as a crystalline aggregate which has a number of crystals. Macroscopic behavior of material can be deduced from the behavior of aggregates. As applications, the extrusion processes are simulated and the changes of mechanical properties are predicted.

Measurements of mean velocity and turbulence characteristics are obtained with a linearized constant temperature hot-wire anemometer in a two-dimensional turbulent jet discharging parallel to a flate. Wall static pressure distribution is also measure. The Reynolds number based on the jet nozzle width (D) is about 42,000 and the step height is 2.5D. The reattachment length is found to be 7.5D by using both wool tuft and oil methods. Upstream of the reattachment point, there exist double coherent structures and mean velocity, Reynolds stresses and triple product profiles are asymmetric about jet center line due to the influence of streamline curvature and recirculating flow region. Near the reattachment point, wall static pressure and turbulence quantities change its shape rapidly because of the large eddies by the solid wall. Especially, turbulence intensity has a maximum value in the reattachment regin, then decreases slowly in the redeveloping wall jet ragion. Downstream of X/D=14, a single large scale eddy structure is formed. Far downstream affer the reattachment(X/D.geq.18) mean velocity profile, the decay of maximum velocity and the variation of jet half width are nearly similar to those of plane wall jet, but the Reynolds stresses are higher than those of the latter.

This experimental study concerns the characteristics of a transitional flow in a concentric annulus with a diameter ratio of 0.52, whose outer cylinder is stationary and inner one rotating. The pressure losses and skin-friction coefficients have been measured for the fully developed flow of $0.1\sim0.4%$ aqueous solution of sodium carbomethyl cellulose (CMC), respectively at inner cylinder rotational speed of $0\sim600rpm$. The transitional flow has been examined by the measurement of pressure losses to reveal the relation of the Reynolds and Rossby numbers with the skin-friction coefficients. The present results show that the skin-friction coefficients have the significant relation with the Rossby numbers, only for laminar regime. The occurrence of transition has been checked by the gradient changes of pressure losses and skin-friction coefficients with respect to the Reynolds numbers. The increasing rate of skin-friction coefficients due to the rotation in uniform for laminar flow regime, whereas it is suddenly reduced for transitional flow regime and, then, is gradually declined for turbulent flow regime. Consequently, the critical(axial-flow) Reynolds number decrease as the rotational speed increases. Thus, the rotation of inner cylinder promotes the early occurrence of transition due to the onset of taylor vortices.

The film coated snap bean (Phaseolus vulgaris) seeds with five different coating materials treated with 3% increase in seed weight were planted at sandy loam soil controlled moisture content of 18, 19, 20 and 21 %. The oxygen diffusion rate (ODR) was calculated from the different moisture content soil. The number of normal seedlings, seedling vigor, and seedling capability in field (seed vigor x dry matter weight) were observed at 9 days after planting and compared to the changes of ODR. The germination rate and ODR were sharply decreased simultaneously in the seeds planted at 21 % soil moisture content. Seedling emergence did not occur at all as the soil moisture content increased above 22 %. Hence this value should be considered as the threshold of soil moisture content for seedling emergence. An ODR value under 20% did not influence the percent emergence significantly. The certain difference observing in the emergence at the same ODR was not related clearly to the condition of soil. So it can be assumed that the limit of soil moisture content for the emergence of snap bean was approximately 20%. The value of 18% soil moisture content may be considered as the optimum for snap bean emergence. There was close relationship between the mean value of ODR in different soil moisture contents and the emergence. The germination rates of the seeds coated with the different materials were quite different when the seeds were planted at 21 % soil moisture. Dry weight of the seedlings from film coated seeds was decreased slightly, but the germination rates were not much different from the non-treated control under relatively higher soil moisture content (21 %). Major factor lowering emergence rate was oxygen stress while film coating act as a minor constraint for snap bean sown in excess soil moisture condition.

Tendocutaneous free flap transfer has been usually used to treat troublesome wounds, which had extensive defect of skin and tendons, since Daniel and Taylor had reported successful free flap transfer in 1973. Among the numerous types of free flap, the dorsalis pedis flap, which could include superficial peroneal nerve, extensor tendon and second metatarsus, was widely used as composite free flap. The authors analysed 13 cases of tendocutaneous free flap transfer from dorsum of the foot which were operated at Korea University Hospital from March 1981 to August 1991. The results were as follows: 1. The average size of these flaps was $53.7cm^2$(mazimum $82cm^2$, minimum $30cm^2)$, the average number and length of tendons were 2.9(maximum, 5, minimum 1), and 9.2cm (maximum 17cm, minimum 5cm). 2. The survival rate of flaps was 100%, and functional results by Dargan's criteria were 4 in excellent, 4 good, 3 fair and 2 poor. 3. The delayed healing on donor site could prevented by the meticulous skin graft and repair of extensor retinaculum. 4. The cases of electrical burn were more worse than the traumatic cases in functional results.

This study examined the relationship between the level of hardiness and self-care agency of persons with a colostomy. The purpose of the study was to explore the effect of hardiness on self-care agency of persons with a colostomy and to identity factors influencing on. The ultimate goal was to help nurses improve the person's self-care agency and to contribute theoretical base for the planning of supportive nursing interventions to increase the level of self care. The subjects for the study consisted of 43 persons aged above eighteen below seventy had had Miles operation and permanent colostomy. The data were collected from July, 1998 to September 15, 1998. The instruments used for this study were the Health-Related Hardiness (Pollock, 1984) and the Self-carer As Inventory Scale(Genden & Taylor, 1988). The Self-Carer As Inventory translated by So Hyang-sook and was modified by author of this study. The data were analysed by using SAS computerlized program and included number, percentage, t-test, ANOVA and Pearson Correlation Coefficient. The results of the study are summarized as follows. 1. Hardiness was significantly related to Self-care agency(r=-0.531. p=0.0002). That is, the higher the hardiness, the higher the level of Self-care agency. 2. In the relationship between general characteristics and traits of persons with a colostomy and hardiness were significant difference in monthly income (F=2.79, p=0.03), problem in stoma management (F=3.29, p=0.01). 3. In the relationship between general characteristics and traits of persons with a colostomy and Self-care agency were significant difference in monthly income (F=2.93, p=0.03), problem in stoma management(F=2.93, p=0.01). Therefore, in order to increase the level of Self-care agency of ostomate Nurses should be helpful to provide them with hardiness training to strengthen their control, commitment and challenge(subconcepts of hardiness).

In this study, we investigate the accuracy of higher order derivatives in the moving least square (MLS) difference method. An interpolation function is constructed by employing a Taylor series expansion via MLS approximation. The function is then applied to the mixed variational theorem in which the displacement and stress resultants are treated as independent variables. The higher order derivatives are evaluated by solving simply supported beams and cantilevers. The results are compared with the analytical solutions in terms of the order of polynomials, support size of the weighting function, and number of nodes. The accuracy of the higher order derivatives improves with the employment of the mean value theorem, especially for very high-order derivatives (e.g., above fourth-order derivatives), which are important in a classical asymptotic analysis.
