In recent years, the widespread application of quality management and measurement reliability has put increasing emphasis on procedures for periodic instrument calibration. By optimizing calibration intervals, unnecessary calibrations can be minimized, thereby reducing costs. Moreover, optimizing intervals will improve compliance with regulatory directives while ensuring maximal compliance with reliability targets. In this paper, we present Calibration Interval Analysis Program developed using several establishment methodologies of calibration interval for measurement quality and reliability improvement. Also, we perform calibration interval analysis for some measurement instruments and analyse its results.

So far the study of near-field optical recording(NFR) suspensions has not been investigated sufficiently. In this study the optimization of a NFR suspension is performed using finite element method. NFR suspensions are required to have low compliance modes to allow the slider to comply with the rotating disk, and high tracking stiffness modes to maximize the servo bandwidth of the tracking controller First of all, a basic integrated type suspension model is obtained using topology optimization And the parametric study on the sensitivities of the compliance modes and tracking stiffness modes is performed. Finally, a model satisfying static characteristics is elected and shape optimization is performed to improve dynamic characteristics.

In this study, to analyse the dynamic characteristics of a machine-tool spindle system, the spindle is mathematically represented by a Timoshenko beam including the internal damping of beam material, and each bearing by four bearing coefficients; stiffness and damping coefficients in moment and radial directions. And the dynamic compliance of the system is calculated by introducing the transfer matrix method, and the complex modal analysis method has been applied for the modal parameter identification. The influence of the bearing coefficients, material damping factor and bearing span on the dynamic characteristics of the system is parametrically examined.

This paper examines the crack growth behavior of 7075-T651 aluminum alloy for small tensile overload under high-low block loading condition. The cantilever beam type specimen with a chevron notch is used in this study. The crack growth and closure are investigated by compliance method. The applied initial stress ratios are R=-0.5 R=0.0 and R=0.25 Crack length, effective stress intensity factor range, ratio of effective stress intensity factor range and crack growth rate etc, are inspected with fracture mechanics estimate.

Coronary intervention is now a well established method for the treatment of coronary artery disease. Coronary restenosis is one of the major limitations after coronary intervention. So medical teams advise the patients to get the follow-up coronary angiogram in 6 months after coronary intervention to know if the coronary artery stenosis recurs or not. This study was done in order to know how many patients complied with the advice, and to identify the relative factors to the compliance with getting the follow-up coronary angiogram. The subjects were 101 patients (male: 58 female: 22, mean age: $61{\pm}15$), who received coronary interventions from Jan. 1st to Mar. 31st 1997, and their data were collected from them by questionnaires one year after intervention. The questionnaires consisted of family support scale, self efficacy scale and compliance with sick role behavior scale. The result may be summarized as follows. 1. The number of patients who complied with getting the follow-up coronary angiogram were 37 people(36.6%) and did not comply with it were 64 people(63.4%). All scores of family support(t=5.56, p<.0001), self efficacy (t=4.13, p<.0001) and compliance with sick role behavior(t=5.66, p<.0001) were significantly higher in the patients who got the follow-up coronary angiogram than in those who did not get it. But there was not any relative factor in demographic variables (p>.05). 2. The major motivations for getting follow-up coronary angiogram were recurrence of subjective symptom(40.5%), the advice of medical team(32.4%), and fear of recurrence (27.1%). The restenosis rate in patients who got the follow-up coronary angiogram was 37.8%. 3. The restenosis rate was higher in the patients who had subjective symptoms than in those who did not have any subjective symptom. So subjective symptom and restenosis rate showed a high positive correlation(r=39.9, p<.001). However, 27.2% of the patients who did not have any subjective symptom showed coronary restenosis. 4. The reasons why they did not get the follow-up coronary angiogram were economic burden(37.5%), improved symptom(34.4%), busy life schedule(10.9%), fear of invasive procedure(9.4%), negative reaction of family member(3.1%), no helper for patient(3.1%) and worry about medical team's mistake (1.6%). The relative fators on compliance with getting the follow-up coronary angiogram after coronary intervention were family support, self-efficacy and Compliance with sick role behavior. And the most important reason why the patients did not get the follow-up coronary angiogram after coronary intervention was an economic burden.

This Study describes the mountainous area which is located in Gyeongsangbuk-do and Jeollanam-do used the relative gravimeter in the object and is measured and the gravity data which used orthometric correction, is a physical height the altitude in compliance with the level measurement which is an altitude and a geometric height is really a difference in compliance with the method which is various calculated orthometric height. In addition, calculated by various were compared & analyzed by orthometric correction against the objective area to determine the appropriate orthometric correction method of calculation.

Analyzing test data of a vehicle for evaluating its emission performance is an essential process in automotive development field, yet it is intricate and tedious task. In addition, clear understanding and care are required when the analysis process is carried out. Computer software solutions significantly reduce the time and the effort for such analysis. Developing a computer routine to analyze the emission data in a vehicle test demands a complete understanding of the emissions analysis and its related details. In this paper, the principals to develop a LabVIEW analysis routine (VI) are introduced helping automotive engineers comprehend the emission analysis process of a vehicle test data and instruct them to develop similar routines for such analysis.

A kinematic analysis method has been used as analysis method for dynamic behavior of moving parts of vehicle, especially hood part. Such analysis method, however, has its limitations in terms of design technology, including, over travel of hood that occurs due to lack of considerations of compliance characteristics, such as flexible components of hood's weather strip and over slam bumper. Therefore, it is necessary to develop a modeling which reflects compliance of flexible components of hood and elastic characteristics of panel for improvement of design process. In this thesis, a finite element method as mentioned earlier, is developed to represent over travel of hood. Also optimization process applying sequential approximate optimization is suggested to prevent over travel. The over travel analysis method and optimization process, which are developed through the research, would make it possible to design with high quality and credibility. Furthermore, it is expected that the time for design would be reduced and the design quality also improved.
