It is very important to measure linear cycle plane positioning accuracy of NC lathes as they affect those of all other machines machined by them in industries. For example, if the linear cycle plane positioning accuracy of each axes directions is bad, the accuracy of works will be wrong and the change-ability will be bad in the assembly of machine parts. In this paper, computer software systems are organized to measure linear displacements of ATC(Automatic tool changer) of NC lathes using linear scale and time pulses comming out from computer in order to get data at constant time intervals from the sensors. And each sets of error data gotten from the test is expressed to plots by computer treatment and the results of linear cycle plane positioning error motion estimated to numerics by statistical treatments.

Revision of KS, Korean Standards, is currently actively discussed. It is just the time for a new world class standards under the new system with WTO, World Trade Organization. This paper is a part of "Researchs on the Standards in the Building Acoustic Field", as one of KS revision projects. The aim of this study is to define the requirements of laboratory test facilities with suppressed flanking transmission. In the former KS, there is no items matched with this purpose. Therefore comparing several results with different measuring conditions of a laboratory and results between different laboratories was impossible. On these basis, a new part of KS is proposed, and some problems remained and further discussions in the proposed draft are described in this study.

Speed log measurement has always been of utmost importance to the mariners. To date the most accurate maritime speed measurement comes from Doppler measurement, where speed may be measured relative to either water(speed through water) or seabed(speed over ground). Recently, a clarification has been issued by the International Maritime Organization (IMO) regarding the speed measuring devices, which could ultimately impact the final arrangement of these devices for ships being constructed after July 1, 2014. This paper will discuss the clarification in depth and necessary action which shall be taken by the owners and operators of the ships impacted.

This study aims to examine validity and reliability of the convergence talent measurement. Based on the comprehensive literature review on convergence and convergence talent, we draw 4 main competencies (convergence cognitive, accomplishment, problem solving, and attitude) and 10 critical aspects (creative thinking, critical thinking, cooperation, communication, problem-solving, knowledge accessibility, resource utilization, trust, openness, caring) for building an effective convergence-oriented organization. A validity and reliability test survey were conducted for the analysis to investigate the convergence talent scale. With a data of 151 employees in diverse companies, the results show that the factors demonstrated acceptable levels of validity and reliability. The empirical evidences of our study are 10 key aspects comprising four main dimensions which suggest an available scale for measuring the convergent talent for enhancing convergence-oriented organizations. Our research contributes to the expansion of academic and practical implications on convergence, especially in convergence-oriented organizations.

It is important to verify that the contracted speed-power performance of a ship is satisfied in sea trials. International Organization for Standardization (ISO) has published the procedure for measuring and assessing ship speed during sea trials. The results obtained from actual sea conditions inevitably include various uncertainty factors. In this study, double run tests were performed on one container ship to analyze the uncertainty of sea trial on three maximum continuous rating conditions. The uncertainty factors and scale of uncertainty were examined based on the measured raw data during sea trial. The results indicate that the expanded uncertainty for ideal power performance is approximately ±1.4% at 95% confidence level (coverage factor k = 2) and most of the uncertainty factors were because of the shaft power measurement system.

Backgrouds : This study was performed to compare the satisfaction levels for health examination programs provided by between the Korea National Health Insurance Corporation (KNHIC) and private healthcare organizations in Korea. We investigated factors associated with the satisfaction level for the KNHIC health examination. Also, factors explaining for the additional receipt of private healthcare organization's examination were identified. Methods : A self-administered questionnaire survey was conducted in June 2004 with 250 beneficiaries of the KNHIC industrial workers' program and 100 beneficiaries of the KNHIC selfemployed program. A total of 297 completed the questionnaire, including 213 (85.2%) and 84 (84.0%) for each insurance program. Ten questions measuring satisfaction levels for each examination program were rated on a scale ranging from 1 (strongly unsatisfied) to 5 (strongly satisfied). Results : Among the subjects receiving both examinations, the mean satisfaction level for the KNHIC examination (3.07) was significantly lower than that for the private healthcare organization's examination (3.50) (p<0.05). The KNHIC examination showed lower satisfaction for all of the 10 items than the counterpart. In particular, the KNHIC examination had the scores of lower than 3.0 for the items reflecting post-examination management services. According to the multiple regression analysis results, the satisfaction for the KNHIC examination was positively associated with the positive attitude toward health examination(${\bullet}$,=0.38, p<0.00). The logistic regression results showed that the likelihood of receiving the private healthcare organization's examination in addition to the KNHIC examination increases as the respondents were less healthier(OR=0.29, 95% CI = 0.10¢¶0.84), the satisfaction level for the KNHIC examination decreased(OR=0.46, 0.28¢¶0.75) or the attitude toward health examination was more positive (OR=2.56, 1.31¢¶5.12). Conclusion : The relatively low satisfaction level for both examination programs suggests that there's ample room for improvement of health examination services in Korea. The negative association between additional receipt of private healthcare organization's examination and satisfaction level for the KNHIC examination implies that the improvement of the satisfaction for the KNHIC examination would help to reduce the national expenditure spent on the additional examination.
