This descriptive correlational study was done to identify ICU nurses' intention to use restraints and related factors using Ajzen and Madden(1986)'s Theory of Planned Behavior. Self-reported questionnaires were used to measure intention and related factors. The subjects of this study were 287 ICU nurses in 21 general hospitals with at least 200 beds at Taegu, Pusan and Kyungbuk area in Korea. The results of this study were : 1. There were significant differences in intention according to age and marnital status, attitude according to educastion(with indirect measure), subjective norm according to career in ICU(with both measures), perceived behavioral control according to age and career in ICU(with direct measure), and knowledge according to education and position. 2. There were significant correlations among intention and all factors. Intention was correlated with attitude(r=.2119), subjective norm(r=.1112), and perceived behavioral control(r=.3448) with direct measure. Attitude was correlated with subjective norm(r=.2530), perceived behavioral control(r=.3005), and knowledge(r=.1388) with direct measure. Subjective norm was correlated with perceived behavioral control(r=.1321) with direct measure. Intention was correlated with attitude(r=.1496) and perceived behavioral control(r=.2922) with indirect measure. Attitude was correlated with subjectivenorm(r=.2829) and knowledge(r=-.1390) with indirect measure. Also, subjective norm was correlated with perceived behavioral control(r=.2363) with indirect measure. 3. ICU nurses' intention to use restraints was explained 16.7% by perceived behavioral control, attitude with direct measure, control belief, and age. By this study, it was foundr that ICU nurses reported high level of intention to use restraints. The most important predictor of intention to use restraints was perceived behavioral control toward using restrains, which reflected the easiness and difficulty in the use of restraints.

This paper measured some condition about differential height of two points for the comparison of measure by direct method and Geodimeter and trigonometric Leveling method. The research was compared relationship between the volue to get from three measure method and five measured man. The significance of between three measure method and five measured man has been investigated by analysis of two-way ANOVA. The result indicate that between five measured man show insignficance, and between the direct method and Geodeter method show signficance and between the direct method and trigonometric Leveling method show signficance but between the Geodeter method and trigonometric Leveling method, two method show insignficant. Therefore, when using Geodemeter leveling method and trigonometric Leveling method, you must keep particular attention when former two Leveling method about instrumental error, natural error, and personal error, two Leveling method using low precision leveling.

Jaw crusher is a device that breaks rock collected from mines or quarries to produce aggregates of the size desired by user. A representative method for measuring load is to measure them by attaching force sensors directly to the part where the load is generated. However, the direct method has many limitations such as high-impact loads generation in equipment or space constraints, sensor capacities and costs. Therefore, Transfer Path Analysis (TPA) was used to indirectly measure impact loads by attaching acceleration sensors. In this study, both direct and TPA methods were used to measure the impact load of Jaw crusher. This study finally quantifies the impact of the load generated by the Jaw crusher using direct method and TPA method, and comparing the impact load measured calculated the derive the error rate.

Direct simple shear test is an effective method to measure strength and deformation properties of soil. However, existing direct simple shear apparatus have some shortcomings. The paper has developed a novel dual stress/strain-controlled direct simple shear apparatus. The novel apparatus has the following advantages: A rectangular specimen is used that effectively avoid common issues associated with conventional cylindrical specimens, such as specimen tilting. The utilization of deformation control rods ensures a uniform shear deformation of the specimen. Vertically integrated force transmission structure is improved that avoids issues arising from changes in pivot points due to lever tilting. Incorporating this novel direct simple shear apparatus, shear strength and shear creep tests of clay were performed. Shear strength parameters and shear creep behaviors are analyzed. The results of these experiments show that the novel apparatus can measure accurately the shear rheological properties of soil. This study provides strong guidance for studying the mechanical properties of soil in engineering practice.

The purposel of this study was to examine the effects which the direct and the indirect instructions at a Home Economics class have on improving the learning achievements and attitudes. To accomplish these goals. 90 students. the number of two classes of the first tirade at p high school at Anyang city of Kyonggi province were selected. They are composed of the experimental group and the comparative group. Each group contained 40 students. The former was implemented by indirect instructions and the latter direct instructions. The 'Family and Domestic Life' unit of the first tirade was selected as the study subject to take effects and 30 periods of class were enforced. For the experimental measure of this study. the researcher used a pre-learning test. a learning attitude test. and a learning achievement test as means of measure. The two groups were confirmed as the group having the same quality, So after the experimental measure, the results of the post tests(included a learning achievement test and a learning attitude test) were verified by T-test in order to research the problematic subject. and SPSS/win statistics package was used for the processing of the statistics. The results are following: 1. The direct and the indirect instructions represented the meaningful differences in the learning achievements (p <.05). They represented the meaningful differences in improving the learning achievements of knowledge and understanding(p <.05). It was verified that the (order is more effective than the latter in improving the learning achievements of knowledge and understanding, and They represented the meaningful differences in the improving learning achievements of application (p <.05) 2. They represented the meaningful differences in the learning attitudes at a domestic class(p <.05) The latter is more effective than the former in changing into the positive learning attitudes. In the light of these result7. the direct instructions are effective in improving the learning achievements of knowledge and understanding. and the indirect instructions are effective in improving the learning achievements of application. Also the indirect instructions are more effective than the direct instructions in changing into the positive learning attitude.

Purpose: This study aimed to develop a scale to measure variables related to alcohol drinking prevention behavior in early elementary school, based on the theory of planned behavior. Methods: A scale was developed to measure variables related to alcohol drinking prevention behavior. Initial items for direct evaluation were constructed through a literature review, and those for belief-based indirect measure were generated through interviews with 30 second- and third-grade elementary school students. The collected data from 286 third-grade elementary school students were then subjected to item analysis, exploratory and confirmative factor analysis, criterion-related validity testing, and internal consistency assessment. Results: The final scale consisted of 35 items. Intention, attitudes, subjective norms, and perceived behavioral control explained 82.7% of the variance; behavioral beliefs, normative beliefs, and control beliefs explained 65.6% of the variance; and evaluation of outcome, motivation to comply, and power of control beliefs explained 72.8% of the variance. The confirmatory factor analysis indicated that the theoretical models had a satisfactory goodness of fit. Criterion-related validity was confirmed between the direct evaluation variables and the indirect measure variables (attitudes r=.64, p<.001; subjective norms r=.39, p<.001; perceived behavioral control r=.62, p<.001). Cronbach's α was .89 for the direct evaluation variables and .93 for the indirect measure variables. Conclusion: The scale developed in this study is valid and reliable. It could be used to measure and explain variables related to alcohol drinking prevention behavior in early elementary school.

Direct manipulations are composed of pointing operations and dragging operations. In order to find the optimum design parameters (such as C/D ratio, moving direction) for the direct manipulation of a GUI(Graphical User Interface), an ergonomic experiment was devised (2*4*3*8 design) to measure the performance of a mouse (Microsoft) and a trackball (Logitech). The results showed that the mouse was more suitable for the direct manipulation (expecially for the dragging operation) than the trackball, and the suitable C/D ratio was 10 (for the mouse) and 16 (for the trackball). Also the movement direction was a determinant factor in trackball performance.

The purpose of this study was to examine the ambivalence of adult children to their elderly parents. 410 adult children who married and having alive mother or father were included. First, direct measurement for asking ambivalence was developed and the relationship between direct and indirect measurements of ambivalence was tested. Next, the influences of parental, children, and relational characteristics on ambivalence were examined. Nine items were selected as direct measurement of ambivalence through the exploratory factor analysis and item response theory. The relationship between direct measure and indirect measure was from .543(p<.000) to r=.625(p<.000) based on gender and generation. The effects of indirect ambivalence on conflict was bigger than direct one for both sons and daughters and the influences of direct measurement on intimacy and relational satisfaction were bigger than indirect one. In case of sons, caregiving obligation was the biggest predictor on ambivalence for mothers and value differences was on ambivalence for fathers. For daughters, age of self was the biggest predictor on ambivalence for mothers and age of fathers was the one for fathers. These results were discussed on the meanings of ambivalence for elderly mothers and fathers in Korea comparing with Chinese and Western cultures.

There have been various direct or indirect methods to measure the characteristics of plasma. Comparing to direct method like Langmuir probe method, indirect measurements which give information as some external parameters like current, voltage, or phase are easier to obtain. In this research, an indirect method to measure averaged plasma density in a transformer coupled plasma(TCP) has been proposed and evaluated. With a simple analytic model connecting electrical characteristics to plasma impedance, direct measurement via double Langmuir probe has been performed. This result may play a meaningful role to diagnose TCP or similar plasma sources

Recently the Korean court accepts two typies of fisheries damages caused by oil pollution.. One is the direct loss of fisheries production originated from pollution of oil spillover. The other is the indirect loss of fisheries production originated from governmental measure of restricting fishing activities because of safety of marine product of oil spillover areas. The paper tries to suggest the appropriated measure of oil pollution damages of hanging and floating netcage aquaculture fisheries using the court judgement for responsibility restriction on Herbei Spirit Case. The paper tries to compare the damge estimation method of floating netcage aquaculture fisheries with that of natural aquaculture fisheries using conventional theory of the population biology of living resources characterized with age distribution.
