In this paper, the task-oriented optimal configuration in the sense of Velocity and Force manipulability measure of manipulator mounted on ROV is considered. Manipulability is a quantitative measure of manipulator's capability obtained under the limits of joint velocities or torques. The base arrangements and optimal joint configuration of manipulator, that maximize the manipulability measure under the constraints of given task, are investigated. With the two types of base arrangements of manipulator, workspace analysis is carried out to investigate merits and demerits of each arrangement on the view of manipulability measure. To find optimal joint configuration for a given task with each arrangement, the SQP(Sequential Quadratic Programming) optimization are performed. Weighted linear combination of velocity and force manipulability measure is object function for SQP optimization. The kinematic parameters of Dual Orion manipulator which will be mounted on KORDI ROV are used for simulation.

It is important to measure the somatic informations for stockbreeding automatization. This study was carried out for the development of wireless measurement system of temperature in living animals. New method to measure somatic temperature was developed using the single-channel wireless instrument. This system was constructed by oscillator, temperature sensor, wireless transmitter and receiver circuit, single processing circuit, and microcomputer. Two types of sensor were used and compared to measure the temperature. The thermistor sensor was more sensitive and accurate than platinum resistance sensor, however both sensors were performed efficiently. The single-channel wireless measurement systems developed could measure the somatic temperature successfully and offered a versatile system.

Ryff's(1989) psychological well-being measure is used to assess and sometimes compare Korean and American adults, however, there is no information regarding whether its dimensions are psychometrically invariant across, whether its items provide sufficient information for, and whether each item measures identical trait levels in, the two nations. Confirmatory factor analysis on response 1,696 Korean and 3,669 American adults, gave to the measure revealed lack of fit and absence of factorial invariance across the two nations. Item response theory revealed significant variance for items on each factor across two countries that most items yielded limited psychometric information. And that each item measure different trait levels, suggesting that in its present form, the measure might lead to misleading results for, and across the two nations.

Purpose: The purpose of this study was to develop performance measure indicators for hospital nursing units based on a Balanced Scorecard (BSC). Method: This study was a methodological study, The development process consisted of 3 stages. The first stage was setting up strategies for nursing units from a nursing department's mission and vision. The second stage was developing performance measure indicators after a validity check. The third stage was modifying developed performance measure indicators and classifying them. Results: 7 strategies were set up according to 4 perspectives of a BSC. 15 performance measure indicators for hospital nursing units were developed, and the indicators were divided into 8 independent indicators and 7 shared indicators according to the degree of performance responsibility. In addition, they were classified into two groups, 7 leading indicators and lagging indicators. Conclusions: The result of this study suggests that performance measure indicators for hospital nursing units provide a framework and method for nursing organizations' performance management. Also, the developed indicators are expected to provide valuable information for successful organization management.

It has been suggested that equity theory a social psychological theory concerned with the fairness in casual relationships should be applicable to marital relationships. This study describes the development of the scale for measuring perception of equity which measure the level of equity in marital relationships among Korean couples. PES(Perception of Equity Scale) is composed of two subscales; detailed measure of equity(DME) and global measure of equity(GME). The PES which include items from two areas of concern for intimates-pschological-emotional concern day-to-day concern-are describes. As results of test reliability of areas of DME range from .86 to .88 and reliability of GME is .92. And there are primarily evidences of construct validity of PES. Therefore PES is very reasonable scale to measure of equity/inequity perception in married couples. Finally analyzing of the level of equity in this sample husbands and wives has generally equitable relationships with their partn rs. Another findings suggest that husbands are overbenefited of their patners through marriage whereas wives are not.

This paper looks at the development of the visual system of robots, and the development of image processing algorism to measure the size of an object and the distance from robot to an object for the visual system. Robots usually get the visual systems with a camera for measuring the size of an object and the distance to an object. The visual systems are accurately impossible the size and distance in case of that the locations of the systems is changed and the objects are not on the ground. Thus, in this paper, we developed robot's visual system to measure the size of an object and the distance to an object using two cameras and two-degree robot mechanism. And, we developed the image processing algorism to measure the size of an object and the distance from robot to an object for the visual system, and finally, carried out the characteristics test of the developed visual system. As a result, it is thought that the developed system could accurately measure the size of an object and the distance to an object.

This paper is to develop a quality measure to evaluate the quality level of child care service in the regional level. By utilizing the biannual intensive child care statistical reports, ten variables are integrated and summarized as a quality measure for child care service in regional level by employing Principal Component Analysis (PCA). Conclusively, it is possible to get a comprehensive measure and the measure obtained from data between 2003 and 2008 illustrates the difference in child care service quality among regions over years. With the measure developed by this research, each region can also get very good insight into what kinds of factors of child care service should be paid more attention to in order to improve the quality of its child care service. Moreover, the measure obtained in this paper is proven reliable and robust in that it reflects the quality of child care service in each region and gives us statistically uniform quality scores with a different data set.

콘투어 맷칭을 위한 1차 유사도와 2차 유사도가 제안되었다. 그것들은 최소자승법에 의한 것이다. 특히 2차 유사도는 콘투어의 불완전함 혹은 어파인 변환 혹은 이들 특성의 결합같은 왜곡된 변화에 양호한 신뢰도를 가지고 있다는 사실을 비행기 기종의 판별과 인식하는 실험을 통하여 증명하였다. 또한 맷칭 성능에 있어서 2차 유사도가 1차 유사도뿐만 아니라 기존의 맷칭기법들보다 우수함을 보였다.

프로젝트 관리의 목표는 프로젝트를 성공하기 위함이다. 그러나 프로젝트 수행 결과가 성공이라고 명확히 판단할 수 있는가? 또한 판단 결과에 고객과 개발자 모두 동의하는가? 성공과 실패에 대한 정의와 판단 척도들에 대해 다양하게 제시되고 있으나 명확한 분류 기준이 없다. 본 논문은 개발 성공을 결정하기 위한 판단척도들을 살펴보고, 프로젝트의 성공과 실패에 대해 재정의한다. 이러한 정의에 의해 프로젝트 수행 결과를 판단하는 척도와 기준을 제시한다. 제시된 판단 척도와 기준을 적용할 경우, 성공과 실패를 분류하는데 고객과 개발자간의 불협화음을 줄일 수 있을 것이다.

Geographic disparity for colorectal cancer (CRC) incidence and mortality according to the human development index (HDI) might be expected. This study aimed at quantifying the effect measure of association HDI and its components on the CRC incidence and mortality. In this ecological study, CRC incidence and mortality was obtained from GLOBOCAN, the global cancer project for 172 countries. Data were extracted about HDI 2013 for 169 countries from the World Bank report. Linear regression was constructed to measure effects of HDI and its components on CRC incidence and mortality. A positive trend between increasing HDI of countries and age-standardized rates per 100,000 of CRC incidence and mortality was observed. Among HDI components education was the strongest effect measure of association on CRC incidence and mortality, regression coefficients (95% confidence intervals) being 2.8 (2.4, 3.2) and 0.9 (0.8, 1), respectively. HDI and its components were positively related with CRC incidence and mortality and can be considered as targets for prevention and treatment intervention or tracking geographic disparities.
