Purpose: To develop a program for analyzing the condition of implanted ICL lenses in case the residual astigmatism appears after the implantation. Methods: From analyzing the measured residual astigmatism after operating ICL lens, we could induce formulas that produce the rotating angle and the corresponding MR prescription of the implanted ICL lens. Using the Delphi 6.0 language, we could develop a program by which we conveniently confirm, in the window screen visually, the rotating angle and the corresponding MR prescription of the implanted ICL lens calculated by these formulas. Results: We induced formulas that produce the rotating angle and the corresponding MR prescription of the implanted ICL lens by analyzing the measured residual astigmatism after operating ICL lens and developed a program which can analyze the condition of the implanted ICL lens. By this program we could easily analyze the condition of the implanted ICL lens. Conclusions: Judging from the results of applying this program to many clinical cases, we could conclude that this program is very effective in analyzing the condition of implanted ICL lenses.

Objective: Optical Coherence Tomography (OCT) has emerged as an important optical imaging modality in non-invasive medical diagnostics. Hence, the aim of this study is to measure the similarity of the diagnosis by a traditional method using doctor's hand for feeling of pulse and by the non-contact/non-invasive pulse analyzing system using OCT on Chon(寸), Kwan(關), Chuk(尺). Method: Four korean medical doctors and the non-contact/non-invasive pulse analyzing system using OCT have measured the rapidity, the dimension, and the power of pulse waves of 25 volunteers. First, four korean medical doctors measured pulse waves of volunteers. During measuring, four doctors were separated from each other and so were volunteers. And then, the pulse waves of volunteers were measured by OCT. This was performed on the right Chon(寸), Kwan(關), Chuk(尺). Results: The study showed that the traditional method and the OCT based method had the 88% matches on the values of the slow and rapid pulse condition (遲數), 64% matches on the values of the small and big pulse condition(微細弱緩大[洪]), and 72% matches on the values of the weak and strong pulse condition(虛實). Conclusions: Based on the high similarities of the measurements of two approaches, we suggest that the OCT based pulse diagnosis method is useful for compensating the traditional method for the pulse diagnosis.

In this study, in order to analyze the effects of dental technology students' degree of satisfaction with their major and sense of self-esteem on college life stress, we conducted a self-administered questionnaire for 270 dental technology students. conducted a frequency analysis, t-test, one-way ANOVA, correlation analysis, and multiple regression analysis, and the results are as follows. As a result of analyzing the degree of major satisfaction, there was a significant difference in the department satisfaction (p<.05). The average score in major satisfaction was relatively high at 3.68. As a result of analyzing the level of self-esteem, there was a significant difference in grade and department satisfaction (p<.05). The average score in self-esteem question was relatively high at 3.75. As a result of analyzing the level of college life stress, there was a significant difference in the department satisfaction (p<.05). The average score for each college life stress area was relatively low at 1.97. As a result of analyzing the correlation between college life stress, major satisfaction, and self-esteem, college life stress was found to have a significant negative (-) correlation with major satisfaction and self-esteem. As a result of a regression analysis conducted on the effect of self-esteem and major satisfaction on college life stress, the variable that most influenced college life stress was found to be the self-esteem factor.

Laser vision inspection systems are becoming popular for automated inspection of manufactured components. The performance of such systems can be enhanced by improving accuracy of the hardware and robustness of the software used in the system. This paper presents a new approach for enhancing the capability of a laser vision system by applying hardware compensation and using efficient analysis software. A 3D geometrical model is developed to study and compensate for possible distortions in installation of gantry robot on which the vision system is mounted. Appropriate compensation is applied to the inspection data obtained from the laser vision system based on the parameters in 3D model. The present laser vision system is used for dimensional inspection of car chassis sub frame and lower arm assembly module. An algorithm based on simplex search techniques is used for analyzing the compensated inspection data. The details of 3D model, parameters used for compensation and the measurement data obtained from the system are presented in this paper. The details of search algorithm used for analyzing the measurement data and the results obtained are also presented in the paper. It is observed from the results that, by applying compensation and using appropriate algorithms for analyzing, the error in evaluation of the inspection data can be significantly minimized, thus reducing the risk of rejecting good parts.

The numbers of the study for 'brand space' had increased gradually from 2003 to 2010 then climbed vertically and the most common study was about place, that shows there is a relationship between variou s social phenomena and human psychology. For the thematic analysis, 'Social psychological components of the brand' based on social psychology was used for analyzing the cognitive aspects, the relational aspects, and the attitudinal aspects. The most common study was the study of the cognitive aspects, and relational aspects, and lastly the attitud inal aspects in order. The strategy was the most common research for the brand associated study. The ultimate point of the strategy is to get 'attitude'. From social psychology perspective, there is a cycle in the minds of consumers, 'Identification', 'Internalization', 'Conformity' and 'Compliance'. Structure of these relationships can provide a clue that consumers' attitude lead the consumers' action.

For the auto-landing operation of an air vehicle, the possibility of auto-landing operation should be first evaluated by testing the navigation performance through a flight test. In general, navigation performance is tested by analyzing north/east/down (NED) errors relative to reference equipment whose precision is about 8~10 times higher than that of a navigation system. However, to evaluate the auto-landing operation of an air vehicle, whether the air vehicle approaches a glide path aligned with the runway, within a specific error, needs to be examined rather than examining the north/east errors of the navigation system. Therefore, the longitudinal/lateral errors of air vehicle heading need to be analyzed. In this study, a method for analyzing the longitudinal/lateral errors of a navigation system was proposed as the navigation performance test method for evaluating the safety during the auto-landing of an air vehicle. Also, flight tests were performed six times, and the safety of auto-landing was examined by analyzing the performance using the proposed method.
