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.

The goal of this study was to examine the current status of science teachers’ stage of concern (SOC) and level of use (LoU) on descriptive assessment and determine the relationship between SoC and LoU. To achieve this, concerns-based adoption model (CBAM) was used, and a survey was conducted on 138 science teachers. The data from this study were analyzed by frequency analysis, percentile analysis based on CBAM, χ² test, and Spearman correlation analysis. SoC and LoU of the science teachers observed in this study are as follows. First, the science teachers’ overall SoC for the descriptive assessment was low and showed a typical pattern of the initial stage when the program was introduced. Second, LoU analysis on descriptive assessment showed that the “mechanical Use” (N=49, 35.5%) or “routine” (N=48, 34.8%) accounted for the majority. Third, the Spearman correlation between SoC and LoU on descriptive assessment was .299(p<.01). This suggests that teachers’ SoC needs to be increased in order to promote higher LoU on descriptive assessment, which requires new alternative measures.

Successful software attacks require both injecting malicious code into a program's address space and altering the program's flow control to the injected code. Code section can not be changed at program's runtime, so malicious code must be injected into data section. Detoured flow control into data section is a signal of software attack. We propose a new software attack detection method which verify the target address of CALL, JMP, RET instructions, which alter program's flow control, and detect a software attack when the address is not in code section. Proposed method can detect all change of flow control related data, not only program's return address but also function pointer, buffer of longjmp() function and old base pointer, so it can detect the more attacks.

SONICS is the software developed by authors. The program provides the noise level in outdoors due to various noise source types : construction machines including blast sources, railroad vehicles and automobiles. h operates in the Windows system. Since the software is compiled by using Visual C++ 4.0, users can run the program interactively. Also SONICS uses Windows' dialog-box and choice-button so that a novice user can easily implement the program for the environmental noise planning.

Purpose : In this study, we applied a computerized cognitive rehabilitation program (CoTras-C) for children with cerebral palsy. Research was conducted to investigate the impact of upper limb function, sensory function, and activities of daily living. Methods : The study period lasted 10 weeks from October 2019 to December 2019. The study subjects were 12 subjects according to the selection criteria, and a computerized cognitive rehabilitation program (CoTras-C) was conducted twice a week for 30 minutes before and after the application of basic occupational therapy. Results : As a result of the computerized cognitive rehabilitation program, scores of upper limb function (QUEST), sensory function (SSP-2), and daily life activity (WeeFIM) were significantly improved (p>.05). From the result of examining the motor area, improvement in fine-motor function and protective extension through touch pad or controller operation was found. It also showed improvement in activities of daily living including motor and activities of daily living including social cognition. In the sensory function evaluation, it was not significant in movement sensitivity. Significant differences were shown in the items excluding olfactory/taste sensitivity. Conclusion : The application of the computerized cognitive rehabilitation program (CoTras-C) showed significant results in upper limb function, sensory function, and daily life activities of children with brain lesions. Based on these results, future studies need to generalize the study by expanding the age or population of children with brain lesions, or by expanding the diversity of diseases and environments.

As the weight of embedded memory within Systems-On-Chips(SoC) rapidly increases to 80-90% of the number of total transistors, the importance of testing embedded memory in SoC increases. This paper proposes IEEE std. 1500 wrapper based Programmable Memory Built-In Self-Test(PMBIST) architecture which can support various kinds of test algorithm. The proposed PMBIST guarantees high flexibility, programmability and fault coverage using not only March algorithms but also non-March algorithms such as Walking and Galloping. The PMBIST has an optimal hardware overhead by an optimum program instruction set and a smaller program memory. Furthermore, the proposed fault information processing scheme guarantees improvement of the memory yield by effectively supporting three types of the diagnostic methods for repair and diagnosis.

This paper investigates efficiency analysis to IT HRD programs in the dynamic perspective. First, empirical result shows that government fund of IT research center is significantly associated with SCI thesis and the more trial goods and SW development is connected with the more patent and technology transfer. Second, ITRC program has been operated efficiently since 2000. Finally, dynamic efficiency analysis implicates that ITRC program is more efficient than other IT SoC program and foreign student support program. The reason why ITRC program is more efficient is generated not from the effect of imitation by catch-up strategy to developed HRD programs, but new operation system introducing and utilizing HRD performance system.

Because of the demands for high performance and high integrated system, the needs for optimal platform becomes more importance. Optimal platform can handle more data effectively with same resources. AMBA(Advanced Microprocessor Bus Architecture)$^{TM}$ defines on-chip communication standard for designing high performance embedded micro-controllers. It is consisted of AHB, ASB and APB. It can support fast implementation and reliability in system that is composed with reusable IPs. DMAC is one of master in system and generate master signals of AHB to communicate data from one slave(peripheral or memory) to another slave. It can reduce burden of CPU and increase system performance. We designed DMAC based on AMBA and it supports 13 Channels. Each channel can be controlled by software program. It decides channel's priority using round-robin method. It can support P2P, P2M, M2P and P2P communication.
