  • The management systems of defense projects need to be well-maintained because of huge cost and long-terms of acquisition & operation in conducting defense acquisition. In this paper, we use a structural equation model(SEM) to develop an project management index(PMI) for effective defense project. The concept of a customer satisfaction index is used to assess the PMI for strategic improvement plans for various characteristics of project management. It is expected that our model can be used to evaluate and improve the project management capability of defense acquisition.

  • For half a century, PMM(Project Management Model) continually has been advanced by many researchers and managers. Especially, the model for civil and construct engineering has now high maturity, but the model for IT engineering has not acceptable maturity. PMI(Project Management Institute) provides the knowledge of protect management for general purpose, it is not adequate for IT prefect management without complements. In this paper, we propose IT project management model based the knowledge of PMI using UML. IT project management model provides not only functions for project planning, budgeting, design and Implement, but also the knowledge for managing IT protect efficiently. We use uses case diagrams to describe the details of the model. We expect the model to be used in management of IT project efficiently in public sector.

  • In this study, a hydraulic flow model and an error correction model are combined to improve the flood simulation accuracy. First, the hydraulic flow model is calibrated by optimizing the Manning's roughness coefficient that considers spatial and temporal variability. Then, an error correction model were used to correct the systematic errors of the calibrated hydraulic model. The error correction model is developed using Artificial Neural Networks (ANNs) that can estimate the systematic simulation errors of the hydraulic model by considering some state variables as inputs. The input variables are selected using parital mutual information (PMI) technique. It was found that the calibrated hydraulic model can simulate flood water levels with good accuracy. Then, the accuracy of estimated flood levels is improved further by using the error correction model. The method proposed in this study can be used to the flood control and water resources management as it can provide accurate water level eatimation.

  • Forensic entomology is a field of study that includes the succession of insects attracted to and found on cadavers. One of its main focusses is estimating post-mortem interval (PMI) based on the growth stage of insects found in and around human cadavers. In many countries, the diversity of insect occurrence is studied in relation to the environmental conditions a cadaver may be exposed to or the effects of different clothes. In this study, changes in the decomposition process and differences in insect succession were investigated by comparing skinned and intact water deer carcasses. Five orders, 15 families, and 21 species of insects were identified, most of which were Dipteran and Coleopteran. The skinned carcass decomposed more rapidly than the intact carcass, which was linked to differences in insect succession. The difference in the decomposition rate and insect succession according to the external conditions of the carcass can be used as basic data for estimating the PMI of the carcass and setting the forensic entomological indicator species.

  • This study was carried out to offer the forensic entomological evidence to estimate the postmortem interval (PMI) based on the decomposing state of the pig carrion and the arthropod succession in exposed carrion. A total of 48 species of 28 families belonging to 7 orders were collected, and dominant insect varied with season, i. e., the Calliphoridae in March, May and October, both of the Calliphoridae and the Staphylinidae in July, and the Staphylinidae in September. The Calliphoridae was the first visiting insect throughout all the seasons as well as the index insect dominant in the early decomposing stage. The index insect in the later decomposing stage, however, was the Staphylinidae throughout all the seasons except in March. In March, the Muscidae was dominant, presumably because the flies consistently arrived throughout the extended period of decomposition of the carrion owing to the low ambient temperature of the season. In this connection, it is known that not only the decomposition stage of the carrion and the carrion-associated insect but also the climatological condition of the region have to be taken into consideration to estimate the PMI.

  • PURPOSE: The purpose of this study was to confirm the effect of exercise combined with scapular stabilizing on resting scapular position (RSP) in breast cancer-related lymphedema patients. METHODS: A total of 20 patients with lymphedema after mastectomy participated in the study. All assessments of the patients edema sides (ES) and non-edema sides (NES) were evaluated. The assessment tools used wad RSP. RSP are; 1) scapular index, 2) 8th thoracic spines process (T8S) to inferior angle of scapular (IA) distance, 3) standing pectoralis minor (PM) distance, and 4) PM index (PMI). All patients carried out a scapular stabilizing exercise seven times a week for 8 weeks. The collected data were analyzed with PASW 18.0. The statistical significance (${\alpha}$) was 0.05. RESULTS: According to the results, all the variable between the ES and NES for RSP were statistically significant (p<0.05) in the pre-test. After the exercise, the differences in T8S to IA distance and the PMI between the ES and NES weren't statistically significant. The results of the RSP showed a significant improvement in T8S to IA distance, standing PM distance, and PMI. CONCLUSION: The results of this study showed that, performing the scapular stabilizing exercise had a significant effect on improving RPS in breast cancer-related lymphedema patients.

  • Project Management Information System (PMIS) has not yet fully met needs of the construction industry. Based on the deficiency of the current system, the present study performed a survey to identify a need for mobile PMIS in the industry. The survey revealed that most respondents expect the development of mobile PMIS would contribute to improving the productivity and efficiency of field operations. Based on the survey findings, this study proposes a suite of modules for mobile PMIS, which are focused on construction management, document management, schedule management, and field information management. Mobile PMIS would allow to access from the field through mobile devices by using tablet computers and smart-phones. The study also suggests that the effectiveness of the system can be enhanced by user interfaces that are customized for each module.

  • PURPOSE: The aim of this study was to investigate the effect of scapular dynamic taping on pain, disability, upper body posture, and range of motion (ROM) in the postoperative shoulder. METHODS: Twenty-two patients who underwent acromioplasty and rotator cuff repair surgery volunteered for this study. The subjects were randomly divided into an experimental group (EG, n=11) and a control group (CG, n=11). For the EG, exercise therapy, manual therapy, and scapular dynamic taping were applied for 6 weeks; for the CG, only exercise therapy and manual therapy were applied for 6 weeks. Shoulder pain, disability, upper body posture, and ROM were evaluated at baseline, after 3 weeks of intervention, and after 6 weeks of intervention. Assessment tools included quadruple visual analog scale (QVAS) for level of pain; shoulder pain and disability index (SPADI) for functional disability level; forward head angle (FHA), forward shoulder angle (FSA), and pectoralis minor index (PMI) for upper body posture; and ROM testing. RESULTS: Significant differences were observed between the EG and CG in SPADI total scores; internal rotation and external rotation ROM of the glenohumeral joint ; FSA ; and PMI. All groups showed statistically significant improvement in QVAS; SPADI; flexion; abduction; external rotation and internal rotation ROM of the glenohumeral joint; FSA; and PMI. CONCLUSION: These results suggest that, for patients who have undergone acromioplasty and rotator cuff repair surgery, the addition of scapular dynamic taping during therapy is effective for improvement of shoulder disability level, ROM, and upper body posture.
