We developed a compact micro indentation testing device (designated SNUT) which is capable to measure Young's modulus of a sample using depth and applied load data during indentation. Performance of this device was evaluated using pure Ti, pure Ni, and die steel (SKD11). As a result of analysing the indentation test data, the frame compliance $C_f$ was found to influence mainly the modulus by 80% among several factors affecting accuracy of Young's modulus. Project area, which was determined by indirect indentation method, was modified using direct SEM observation. Finally, Young's modulus error was reduced to 5% after taking into consideration the frame compliance and modified projected area from 80% error without any these two correction factors. The performance of SNUT and MTS instruments was compared using same specimen (pure Ti).

It is important to calculate the exact crack opening area in the cracked pipe subjected to axial force and bending moment. Among many solutions for obtaining the crack opening displacement, Paris-Tada's expression, which is derived from energy method, is open used in fracture analysis for piping crack problems because of its simplicity. But Paris-Tada's equation has conservativeness when radius over thickness ratio(R/t) is ten or less, for it is based on the stress intensity factor solution having a compliance function derived from a simple shell theory. In this paper we derived a new expression using a different stress intensity factor solution which is able to consider the variation of compliance through wall thickness in a cracked pipe. Conservativeness of both equations was examined and compared to finite element analysis results. Conservativeness of the new equation is decreased when R/t > 10 and increased slightly when R/t < 10 compared with Paris-Tada's. But Both equations were highly conservative when R/t < 10 compared with finite element analysis results.

OSHA(Occupational Safety and Health Act) generally regulates employer's business principles in the workplace to maintain safety environment. This act has the fundamental purpose to protect employee's safety and health in the workplace by reducing industrial accidents. Authors tried to investigate the correlation between 'occupational injuries and illnesses' and level of regulation compliance using Survey on Current Status of Occupational Safety & Health data by the various statistical methods, such as generalized regression analysis, logistic regression analysis and poison regression analysis in order to compare the results of those methods. The results have shown that the significant affecting compliance factors were different among those statistical methods. This means that specific interpretation should be considered based on each statistical method. In the future, relevant statistical technique will be developed considering the distribution type of occupational injuries.

This paper presents a stiffness analysis method for a low-DOF parallel manipulator, which takes into account of elastic deformations of joints and links. A low-DOF parallel manipulator is defined as a spatial parallel manipulator which has less than six degrees of freedom. Differently from the case of a 6-DOF parallel manipulator, the serial chains in a low-DOF parallel manipulator are subject to constraint forces as well as actuation forces. The reaction forces due to actuations and constraints in each limb can be determined by making use of the theory of reciprocal screws. It is shown that the stiffness model of an F-DOF parallel manipulator consists of F springs related to the reciprocal screws of actuations and 6-F springs related to the reciprocal screws of constraints, which connect the moving platform to the fixed base in parallel. The $6{times}6$ stiffness matrix is derived, which is the sum of the stiffness matrices of actuations and constraints. The six spring constants can be precisely determined by modeling the compliance of joints and links in a serial chain as follows; the link can be considered as an Euler beam and the stiffness matrix of rotational or prismatic joint can be modeled as a $6{times}6$ diagonal matrix, where one diagonal element about the rotation axis or along the sliding direction is zero. By summing the elastic deformations in joints and links, the compliance matrix of a serial chain is obtained. Finally, applying the reciprocal screws to the compliance matrix of a serial chain, the compliance values of springs can be determined. As an example of explaining the procedure, the stiffness of the Tricept parallel manipulator has been analyzed.

Purpose: The objective of this study was to identify the effects of a telephone follow-up program on patient compliance, urea kinetic modeling and incidence of infection in patients with continuous ambulatory peritoneal dialysis (CAPD). Method: A pretest-posttest design with a nonequivalent control group was used to examine the effects of a telephone follow-up program for 12 weeks in a group of 39 CAPD patients. The telephone follow-up group of 17 patients received telephone follow-up 10 min once a week for 1 month and 10 min twice a month for 2 months during 12 weeks compared to control group of 22 who patients received usual care. Results: The telephone follow-up group showed no significant changes in patient compliance and urea kinetic modeling, although patients with CAPD receiving a telephone follow-up showed reduced incidence of exit site infection during the intervention compared with the control group. Conclusion: Telephone follow-up program for CAPD patients may decrease the incidence of exit site infection. Future studies with a larger sample be done utilizing diet and exercise reinforcement program combined with telephone follow-up as a nursing intervention for patients with CAPD.

Objectives : To analyse the psychosocial factors associated with hypertension management(drug treatment and life style modification) of newly detected cases and to understand and assess their behavioral intention or behaviors. Methods : The survey area was a combined urban and rural area in Chungnam province, Korea, and the sampling method was cluster sampling. Study subjects included 541 newly detected cases of hypertension rated above stage 2 by JNC-VI from a community survey. The first survey was applied to 383 of these patients in order to discern their psychosocial characteristics. A follow-up survey was given to 345 persons with an 11-month interval following monthly telephone counseling concerning medication and life style modification by trained nurses. The final study subjects for analysis comprised 271 persons after excluding cases of incomplete data and change of address. Results : Among the 85(33.2%) new patients who had intended to undergo drug treatment, 30(35.3%) persons were treated with antihypertensive agent after 11 - month interval, while among the patients with no intention to receive treatment, only 36(21.1%) persons were treated. Hypertensive patients with a high intention score revealed a high score in life style modification compliance as well. Seventy three percent of the variance of behavioral intention to undergo hypertension management was explained by the patients attitude toward performing the behavior and subjective norm associated with behaviors related to the theory of reasoned action in structural modeling. Actual behaviors related positively with behavioral intention. The coefficient of determination was 0.255. Conclusion : Improving the compliance level of hypertensive patients in respect to drug treatment or life style modification requires a build up of positive behavioral intention, and caregivers must pay more attention to eventually converting behavioral intention to actual behaviors.

This study investigates the effect of spatial averaging and compliance taken account of in the analysis of earthquake-induced permanent deformation of slopes. At present, the rigid block analysis originally proposed by Newmark is widely used in the deformation analysis, mainly because of its computational efficiency. This type of approach, however, adopts the so-called decoupled approach, in which seismic response and deformation analyses are carried out separately. Original Newmark block analysis assumes the potential sliding mass to be noncompliant, and has been criticized to be potentially unconservative. This paper reviews the impact of the noncompliance assumption of the potential sliding mass in the Newmark-type analysis. The gross effects of earthquake shaking on the potential sliding mass are estimated by spatial averaging method and analyzed in frequency domain. The results indicate that there is a simple criterion that can be used to determine the level of compliance of the potential sliding mass.

The bearer of the power sector's ETS compliance cost is power consumer for the following reasons. Firstly, power companies are constrained in establishing appropriate strategies to comply with ETS regulations due to the structural differences between the domestic power market and emission trading system. In other words, because power companies do not have a right to determine price and production of electricity, they have to compete with other companies under disadvantaged conditions in the emission trading market. Secondly, because ETS compliance cost is part of power production costs as it is also clearly written in the national greenhouse gas reduction road-map and the second energy supply plan, the cost should be included in power price following the power market operation rule. Thirdly, the most effective method to reduce carbon emissions in power sector is to reduce power demand, which is efficiently achieved through raising power price to a realistic level. Low power price in Korea is the major cause of rising power demand which is also the major cause of rising GHG emission. Therefore, power sector's ETS compliance cost should be included in power price to encourage power consumers' actions on reducing power consumption. Fourthly, when externality cost occurs in the process of delivering public services, usually beneficiary pay principle is applied to identify the cost bearer. Since electricity is one representative public good, the bearer of power sector's ETS compliance cost is power consumer.
