The study supports not only the implicative results and strategic implication to social media staff and managers, but also extended the marketing studies in Korean financial institutions. This paper examined the effect of market orientation on social media marketing performance in the Korean financial institituions. Narver and Slater's market orientation theory was employed for the structural equation model framework. Indirect and direct implication on the social media marketing performance were analyzed. This study conducted online survey social media marketing staff and managers in 230 Korean financial institutions such as banks, securities, asset management, credit card, insurance companies. 102 responses were collected and analyzed. The results revealed that financial institutions' customer orientation, competitor orientation and inter-functional coordination have a positive impact on marketing communications execution degree but not direct effect on social media marketing performance except competitor orientation. Although it does not appear to have a statistically significant association between market orientation two concepts such as customer orientation and inter-functional coordination, and social media marketing performance directly, the competitive orientation has statistically positive impact.

In recent high-performance superscalar processors, the result value of an instruction is predicted to improve instruction-level parallelism by breaking data dependencies. Using those predicted values, instructions are speculatively executed and substantial performance can be gained. It, however, requires additional power consumption due to the frequent access and update of the value prediction table. In this paper, first, the trade-off between the performance improvement and the increased power consumption for value prediction is measured and analyzed. And, in order to reduce additional power consumption without performance loss, the technique of controlling speculative execution with confidence counter and predicting useful instructions is developed. Also, in order to prove the validity, a tool is developed that can simulate processor behavior at cycle-level and measure total energy consumption and power consumption per cycle.

상위 수준 합성 과정에서 스케줄링은 하드웨어 동작을 표현한 연산들이 주어진 제약 조건을 만족하며 최적의 제어단계에 배정되도록 하는 과정이며 스케줄 결과는 목적 하드웨어의 면적과 실행속도에 많은 영향을 준다. 파이프 라인은 순차적인 데이터 입력을 중첩 수행하여 실행 속도와 자원 이용률을 동시에 증가시키는 방법이다. 상위 수준에서 파이프라인 데이터 패스를 합성하기 위한 기존의 스케줄링 알고리즘들은 고정된 데이터 입력 간 격열을 기반으로 제안된 것이 대부분이며, 가변 데이터 입력 간격을 지원하는 스케줄링 알고리즘으로는 시간 제약 하의 자원최소화 알고리즘[5]이 제안되었다. 본 논문에서는 가변데이터 입력 간격을 지원하는 자원 제약하의 실행 시간 최소화 알고리즘을 제안한다. 이를 위해 연산의 스테이지 인덱스가 초기에 고정되는 시간제약하의 스케줄링 알고리즘[5]을 응용하여 자원제약하의 스케줄 진행과정에서 증가되는 제어단계에 따라 스테이지 인덱스가 변경 될 수 있도록 하고 점진적인 모빌리티 축소에 의해 스케줄한다. 제안된 스케줄링 알고리즘의 실험 결과는 다양한 자원제약과 입력 간격렬에 대하여 제약조건을 만족하는 효과적인 스케줄 결과를 유도한다.

컴퓨터 게임의 발달은 오프라인 PC 게임에서 인터넷의 보급으로 인해 온라인 게임으로 발전하였다. 그 후 인터넷 환경은 유선 환경뿐만 아니라 무선 환경에서도 무선 단말기를 이용하여 게임 서비스가 가능한 수준에 이르렀다. 그러나 적은 메모리와 낮은 수준의 처리능력을 가지고 있는 제한적인 모바일 환경의 특성으로 유선 인터넷에서와 같이 멀티미디어를 포함한 다양한 형태의 정보제공 및 인터렉티브한 모바일 게임이 어려운 현실이다. 본 논문에서는 WAP(Wireless Application Protocol)을 기반으로 하여 다운로드 솔루션을 채택한 GVM(General Virtual Machine) 상에서 실행될 수 있는 모바일 게임을 설계하고 MobileC 언어를 사용하여 제작하였다. 또한, 모바일 게임을 설계하고 제작하는 과정을 통해서 단말기의 제한적인 실행환경에서 최대한의 효과를 나타낼 수 있는 개발 모델을 제시하고자 한다. GVM은 무선 단말기 상에서 동적인 응용프로그램을 실행할 수 있는 가상기계 플랫폼이다.

We perform static program analysis for the binary code. The reason you want to analyze at the level of binary code, installed on your local computer, run the executable file without source code. And the reason we want to perform static analysis, static program analysis is to understand what actions to perform on your local computer. In this paper, execution flow graph representing information such as the execution order among functions and the flow of control is generated. Using graph, User can find execution flow of binary file and calls of insecure functions at the same time, and the graph should facilitate the analysis of binary files. In addition, program to be run is ensured the safety by providing an automated way to search the flow of execution, and program to be downloaded and installed from outside is determined whether safe before running.

Schedulability analysis is necessary to build reliable embedded real-time systems. For schedulability analysis, worst-case execution time(WCET) analysis that computes upper bounds of the execution times of tasks, is required indispensably. WCET analysis is done in two phases. The first phase is high-level analysis that analyzes control flow and finds longest paths of the program. The second phase is low-level analysis that computes execution cycles of basic blocks taking into account the hardware architecture. In this thesis, we design and implement integrated WCET analysis tools. We develop the WCET analysis tools for XScale-based system called WATER(WCET Analysis Tool for Embedded Real-time system). WATER consist of high-level flow analyzer and low-level execution time analyzer. Also, We compare real measurement for execution of program with analysis result calculated by WATER.

The objective of this study is to develop an IS curriculum and its action plan for footwear industry based on the Instructional System Design(ISD) that is widely used in curriculum developments. To this end, six steps, including a goal setting, analysis, design, development, implementation, and evaluation are employed. Firstly, the explicit goal of IS curriculum development is defined and demands of IS education from the footwear companies are identified with questionnaires and interviews. In the design stage, the IS curriculum map is presented. With this map, the specific IT courses are established, classified by a type of industry, a function, and a level of skills. For the implementations, such particular actions as a selection of textbooks, places, managing trainees, and a training support plan are explained. Finally, the various evaluation methods are presented. The suggested IS curriculum can be applied to IS educations for the footwear companies and other related industries.

This study aimed to assess the feasibility and impact of a 5-week parent-led home-based music program for parents of children with autism spectrum disorder (ASD). The program aimed to enhance the parents' sense of competence and their relationships with their child. Each week for 5 weeks, 10 parents of 10 children with ASD (aged 3 to 9 years) received weekly 30-minute personalized lessons on how to implement the home-based music program and implemented the educated music program at home with activities involving receptive and active engagement. On average, the parents conducted the music program 2.5 times a week for about 9.2 minutes per session. At the end of the 5 weeks, parents reported increased comfort and effectiveness in interacting with their child through music. In addition, positive changes were noted on the Parenting Sense of Competence Scale and the closeness aspect of the parent-child relationship. Participants affirmed the program's feasibility, emphasizing its potential for supporting families with children with ASD. These results provide foundational data for future home-based music activities and programs, emphasizing the importance of tailoring interventions to the unique needs of families with children with ASD.

Objective: The purpose of this study is to investigate the effects of childcare teachers' teacher efficacy, psychological burnout and the practice of respecting rights for infants. Methods: For this study, questionnaires were distributed to 398 childcare teachers in the cities of I and S. The collected data were analyzed by descriptive statistic, multiple regression and Cronbach's ${\alpha}$ for reliability by SPSS-WIN computer program. Results: The results yielded some interesting results. First, childcare teachers were shown to have higher respecting rights for infants but just average teacher efficacy rates. Secondly, the study showed a positive correlation between the practice of respecting rights for infants and childcare teachers' teacher efficacy. However, there was a negative correlation between the practice of respecting rights for infants and psychological burnout. There was also a negative correlation between the practice of respecting rights for infants and childcare teachers' teacher efficacy. Third, the higher the childcare teachers' teacher efficacy of childcare teachers, the more positive influences existed in the practice of respecting rights for infants. It also showed that the lower the degree of psychological burnout, there was a negative impact on the practice of respecting rights for infants. Conclusion/Implications: The results of this study suggest that a support plan is needed to boost childcare teachers' teacher efficacy, and to lower the psychological burnout of childcare teachers with regards to the practice of respecting rights for infants.
