  • This paper measures integrated pollution intensities and changes in pollution intensity, and figure out environmental performance. We introduce a new definition of pollution intensity and its method measuring integrated pollution intensities. We distinguish 24 manufacturing industries into light industry and heavy industry, and divide heavy industry into pollution industry and the other residual heavy industry to measure the integrated pollution intensities and their changes. While the pollution industry within heavy industry, based on the integrated pollution intensity, was the most pollution-intensive, the other residual heavy industry within the heavy industry was the most successive in reducing pollutants. The annualized average index of the integrated pollution intensities grew as much as 9.1 percent, of which the annualized change in the index of pollution emission increased 13.3 percent, but the improvement of 3.9 percent in the change of output quantity offset the increase in the index of pollution emission. The changes in the integrated pollution intensity for the light and heavy industries were 1.125 and 1.042, respectively. The reason the heavy industry showed the lower change in the index of pollution intensity, while the change in the pollution industry was very high, was because the average change in the other heavy industry decreased around 9 percent.

  • This paper presents an integrated method for aircraft position estimation using sequential aerial images. The proposed integrated system for position estimation is composed of two parts: relative position estimation and absolute position estimation. Relative position estimation recursively computes the current position of an aircraft by accumulating relative displacement estimates extracted from two successive aerial images. Simple accumulation of parameter values decreases reliability of the extracted parameter estimates as an aircraft goes on navigating, resulting in large position error. Therefore absolute position estimation is required to compensate for the position error generated in relative position estimation. Absolute position estimation algorithms by image matching or digital elevation model (DEM) matching are presented. In image matching, a robust oriented Hausdorff measure (ROHM) is employed whereas in DEM matching an algorithm using multiple image pairs is used. Computer simulation with four real aerial image sequences shows the effectiveness of the proposed integrated position estimation algorithm.

  • Purpose: The purpose of this study was to investigate the effects of an integrated management program on climacteric symptoms and depression in middle-aged women. Methods: A nonequivalent control-group design was used. The subjects consisted of 65 middle-aged women with climacteric symptoms. The experimental group (n=33) participated in the program for six 60-min sessions. To measure the climacteric symptoms and depression level of the subjects, two self-reporting questionnaires were used. Data were analyzed using SPSS Statistics 17.0 program. Results: The women in the experimental group reported the average score of 13.80 in climacteric symptoms, 14.38 in depression. The hypothesis that the climacteric symptoms of experimental group would be reduced more than that of the control group was supported (t=3.92, p<.001): physical symptoms (t=4.04, p<.001); psychological symptoms (t=1.80, p=.077); sexual symptoms (t=2.85, p=.006). The second hypothesis that the degree of depression of the experimental group who used the integrated climacteric symptoms management program would be reduced more than that of the control group was also supported (t=2.30, p=.02). Conclusion: The integrated management program for middle-aged women with climacteric symptoms was effective in reducing their climacteric symptoms and depression level.

  • The purpose of this study is identify the status of the ward of public hospital for integrated nursing care service. Integrated nursing care service has been expanding on a national scale from 2016 but most of public hospitals are currently unable to operate due to nursing shortage. In this study 8 wards of public hospital have been chosen and analyzed. The measure of space program and area distribution(patient area percentage, staff area percentage, circulation area percentage), nurses's walking distance(distance from ns to patient room, distance from ns to core) were calculated by depthmapX and autocad programs. The result of this study is as follows. Nurse's walking distance is more than 24m so the efficiency of nurse's patient care is reduced. The percentage of patient area in double-corridor is higher and the patient feels more comfortable but the Nurse's walking distance is longer and the accessibility is lowered. NS should be located in the center of the ward and close to the core but some wards are not composed of proper space-separation and flow of human trrafic is overlapped. This study may serve as basic research for the architectural plan for future integrated nursing care ward.

  • Delay claim should actually be supported by a set of proper information so that the contractors could prove their validity. The so-called information should be able to clarify the relationship between delay events and how they impact on the whole project. Therefore, exploiting an integrated system by people who are involved in construction business would certainly prove helpful. In the present study, delay analysis methods have been investigated along with selecting a relatively comprehensive method which has been modified, and eventually, a novel model and its required modules have been proposed for evaluating delay claims. The suggested integrated model is formed to identify delayed events, to classify delays, to measure the impacts of delays on the project scheduling, and finally to estimate the damages which were caused by those so-called delays. A decision support system (DSS) model which is related to the integrated system is actually extracted from Iran's general contract conditions, that is, 4311 magazine (equivalent to red FIDIC book). It is then programmed and coded by C# program. This DSS model can be used as an input of Easy Plan program. In addition, at the end of this research, the coded DSS has been used along with the so-called program so that a modified and developed model could be generated.

  • In this paper, we study the methodology for the measurement and integration of market risk and credit risk using Copula. We apply the methodology of Rosenberg, and Schuermann(2006) to the assets of pension system. Firstly we estimate dynamics of risk factors and their effects on investment returns, then use the estimated result to simulate future movement of risk factors and distribution of investment returns. Finally we measure integrated risk using integrated return distribution by Copula and simulated future investment return distributions. We found the integrated risk changing with the correlation of risks and investment weights of risks and confirmed the diversification effect of risks. This result is consistent when we use normal Copula and normal marginals, t-Copula and t(3) marginals, and normal Copula and non-parametric marginals. And in the case of non-parametric maginals, larger integrated risk is calculated. It means that use of non-parametric marginals is more conservative.

  • Busan Port is being operated inefficiently by a number of container terminal operators, which are dispersed in small groups. In particular, the small terminal at Busan Port is causing the dispersion of quantity, the increase of ITT cargo and the occurrence of a ship waiting at sea as the ship's Alliance became larger in 2016. As a result, studies such as integrated operations for the larger container terminals are being conducted. Therefore, in this study, we intend to set up a type of integrated operation for terminals at the new port of Busan and measure the practical effects through simulation to present an ideal direction for integrated operation.

  • A photonic integrated interferometric imaging system possesses the characteristics of small-scale, low weight, low power consumption, and better image quality. It has potential application for replacing conventional large space telescopes. In this paper, the principle of photonic integrated interferometric imaging is investigated. A novel lenslet array arrangement and lenslet pairing approach are proposed, which are helpful in improving spatial frequency coverage. For the novel lenslet array arrangement, two short interference arms were evenly distributed between two adjacent long interference arms. Each lenslet in the array would be paired twice through the novel lenslet pairing approach. Moreover, the image reconstruction model for optical interferometric imaging based on compressed sensing was established. Image simulation results show that the peak signal to noise ratio (PSNR) of the reconstructed image based on compressive sensing is about 10 dB higher than that of the direct restored image. Meanwhile, the normalized mean square error (NMSE) of the direct restored image is approximately 0.38 higher than that of the reconstructed image. Structural similarity index measure (SSIM) of the reconstructed image based on compressed sensing is about 0.33 higher than that of the direct restored image. The increased spatial frequency coverage and image reconstruction approach jointly contribute to better image quality of the photonic integrated interferometric imaging system.

  • Objective: This study aimed to examine childcare teachers' perceptions and practice of music-math integrated activities, and their understanding of these activities. Methods: This study involved 201 childcare teachers from Seoul and surrounding areas. Surveys were employed to collect data on their background, implementation of music-math integrated activities, and the challenges they encountered. Additionally, a tool was also developed and utilized to measure the actual understanding of these activities. Data were analyzed using t-tests and ANOVA. Results: The results indicated that while teachers recognize the importance of integrated activities, they seldom implement them due to challenges related to resources and comprehension of concepts. Significant differences in the understanding of these activities were found based on teachers' experience, workplace type, age group of children under their care, and education level. Conclusion/Implications: In conclusion, the findings emphasize the necessity for the development and provision of pre-service and in-service training programs, along with support in educational materials for childcare teachers. These efforts are crucial to facilitate the effective implementation of music-math integrated activities.
