The goal of this study is to assess the effects of Scratch programming classes on preservice teachers by using computational thinking and cognitive evaluations based on Bloom's taxonomy. To pursue this research goal we measured preservice teachers' programming skills using cognitive evaluation items based on Bloom's taxonomy after preservice teachers took one-semester Scratch programming course. In addition, a survey focused on computational thinking (CT) concepts, CT practices, and CT perspectives was conducted. We also conducted artifact-based interviews to unpack preservice teachers' experiences of working on team projects and analyzed their experiences qualitatively. The results of this study are meaningful because we assessed preservice teachers' experiences comprehensively with both quantitative and qualitative methods. In addition, this study provides us with implications for evaluation perspectives in designing programming courses for preservice teachers by adopting Bloom's taxonomy scheme.

There are generally two types of groundwater vulnerability assessments. Intrinsic vulnerability is based on the assessment of natural climatic, geological and hydrogeological attributes and specific vulnerability relates to a specific contaminant, contaminant class, or human activity. Several methods to assess groundwater vulnerability, which are based on hydrogeologic setting and socio-economical environment, have been developed in USA and Europe. A Modified-DRASTIC model including a lineament factor has been developed in South Korea, but it still has some limitations. To develop a solid and applicable method in this country, many data of quality, hydraulic features, GIS data, and pollution source, produced from a Basic Survey based on Article 5 of the Groundwater Act and other research projects, need to be collected, analyzed and verified introducing the previous methods.

The construction industry has been behind in informatization compared to other industries such as banking, manufacturing, medical, etc. since it is not conscious of informatization and it also has difficulties in attracting investments and attracting IT experts. Furthermore, there has been lack of survey and research on that specifically what areas and how much degree they are behind in informatization. This paper presents a framework and strategy for assessment of informatization based on end users' viewpoints. The authors has already performed the assessment of informatization of general contractors based on IT experts' viewpoints. However, this paper tries to assess informatizaton of construction based on end users' aspects. The result of this research is expected to provide various aspects such as assessment, identification of needs, and problems regarding information systems. These could be effectively used as a guideline and a direction for information system development.

In the system integration (SI) industry, improving relationships with outsourcing partners is one of the key challenges faced by SI companies that aim to increase productivity and reduce costs. In the SI industry, over 80% of project development work is performed by these outsourcing partners. Hence, large SI companies focus on fostering high-performing partners through improved cooperation and mutual relations. However, in the SI industry the existing process of managing outsourcing partners is unable to advance to the level of long-term partnerships due to inadequate information sharing and communication in the process of selecting and assessing a potential and existing partner. Based on the theory of partnership, this study identifies the success factors for new strategic partnerships. Further, this study presents a model for assessing partner companies to promote increased productivity and improve the relationship between an SI company and its partner. In addition, this model is used to assess partner relationships for a well-known SI company "A". This study explores the feasibility of a new framework model.

Project-based learning is an effective teaching method for improvement of academic achievement and problem-solving ability so that is often applied to programming education. However, a strategy of enhancing motivation is required by a course design considering a learning style of students for advantage of PBL to take effect. Yet, studies on considerations with learning style still lack, when designing project-based programming learning courses for improvement of learning motivation. This research aims to address issues for consideration in designing PBL programming course. Accordingly, we analyzed learning motivation's difference between learning style in PBL programming class. We designed PBL programming course focusing ARCS model, where students making simulation The Kolb Learning Style Inventory is used to determine learning preferences. To assess students' motivation, Keller's Course Interest Survey was used in a pre-post-test-design. The result indicates that pre-post students' motivation differed. Also, we found considerations through comparing difference of ARCS model's detailed elements between learning styles.

In spite of the size and complexity of software becomes large and complicated, the demand of rapid development, cost reduction, good productivity and good quality software is increasing in these days. Many methods were proposed for efficient software development such as various Case tools. Metrics, Process improvement model (CMM, SPICE, ISO9000) and etc. However, most of them we useful to manage the whole projects rather than an individual programming. In this paper, we introduced a system for quality assessment and complexity metrics for Java programs to assess the individual programmer's quality rather than team's quality. This system shows not only the metrics value for quality assessment but also the source code and the soucture of classes simultaneously.

The purpose of this study was to investigate the effects of dark side personality traits on self-other rating agreement in leader effectiveness. Data were collected from 80 team leaders and their peers in college. Peers who conducted a team project were asked to assess performance of their team leaders on leader effectiveness, task performance, and contextual performance. The leaders were also asked to self-rate their performance on the same measures. Results indicated that there was disagreement of perceptions about personality traits between leader's self-ratings and the rating of others. First, leaders considered their own Bold, Diligent behaviors as positive influence on their leadership-related criteria, whereas peers of these leaders provided negative ratings. Also, leaders viewed Leisurely and Cautious characteristics as unrelated or negative to performance, whereas peers perceiveed these personality traits as positive to performance. Suggestions for future research were provided based on the findings.

USA is strengthening the information sanity by managing federal agency's information and information system systematically. For this purpose, US government put the Federal Information Security Management Act into the E-Government Act of 2002. According to the FISMA, it is required to have information security management plan for ail federal agencies. In addition that, Inspector Generals of these agencies should assess the status of their agency and report the result to the office of Management and Budget. Collecting all the reports from each agency, OMB should report to GAO on general status of information security of federal agency. It is helpful to provoke the information security as a necessary activity to realize the E-government. Comparing these efforts with our system will give us good implications to get more idea to secure our information system.

Existing dozer productivity computation models use different input variables, formulas, productivity correction factors, and experimental data source. This paper presents a method that characterizes the productivity outputs obtained by the PLS model and the Caterpillar model that are accepted as industry standards. The method identifies the input variables to be collected from the site, the performance charts to be referenced, and the formulas and implements them in a single computational tool. This study verifies that the PLS model may replace the manual computational process of Caterpillar model by eliminating reliance on graphics manipulation. Replacing the Caterpillar model with the PLS model and implementing the process as a function contributes to assess the productivity of a dozer timely by encouraging to utilize real-time information collected directly from the site. This study allows researchers and practitioners to effectively deal with the values of productivity correction factors collected from the job site and to control the productivity. The practicality and effectiveness of the method have been validated by applying to a project case.
