With an increase in demand for the high added value of shipbuilding and marine industry based on the information and communications technology (ICT), software technology has become more important than ever in the industry. In this paper, we present the result of our preliminary investigation on the current software development environment in the shipbuilding and marine industry in order to develop reusable software component, which can enhance the competitiveness of software development. The investigation is performed based on the survey answers from 34 developers who are working in different shipbuilding and marine companies. The questionnaire is composed of items to gather the information of each company such as the number of employees and product domain, and actual software development environment such as operating system, programming languages, deployment format, obstacles for developing components, and the adoption of software development methods and tools. According to the results of the survey, the most important consideration to select their development platform was the number of available utilities and the technical supports, followed by performance, price and security problems. In addition, the requirements of various platforms supporting and the higher reliability, and the limitations of low development cost and manpower made it difficult for them to develop reusable software components. Finally, throughout the survey, we find out that only 15% of developers used software development processes and managed the quality to systematically develop their software products, therefore, shipbuilding and marine companies need more technical and institutional support to improve their ability to develop high qualified software.

Objectives: This study is an explorative study for developing an instrument to measure habitual physical activity level of school-aged children. Methods: HPAQ-S consists of 41 items and a self-reported 5-day recall instrument designed to assess habitual physical activity level for school-aged children. For the validity and reliability test, a sample consisted of 28 children, aged 10-11 years old. Results: 41 question items showed an acceptable internal consistency (cronbach's alpha=.89). A significant positive correlation with the pedometer results (r=.69, p<.001) and with Borg's questionnaire (r=.76, p<.001) support the validity of HPAQ-S. Conclusion: HPAQ-S may be more useful for measuring habitual physical activity level of elementary school-aged children in large populations.

In order to reduce the possible quality problems in the construction stage. This research will develop a quality management support tool based on Mobile BIM. In order to develop the tools of this study, the procedures of domestic quality management work were analyzed, and 12 functions were derived to solve the existing problems, and the process of mapping checklists by work type and BIM model objects was performed. Finally, through the questionnaire survey on the usefulness of the tool in the actual field, the possibility of props in actual supervision business is verified.

The purpose of this study was to develop and validate a mathematics anxiety scale for elementary students in South Korea. Based on the literature review, I developed two types of survey items measuring elementary students' mathematics anxiety. Teachers or students may use survey measurements selectively according to the students' participants in mathematics private institutions. In order to assess the reliability and validity of survey items, I conducted surveys with elementary students. The sample consisted of 300 elementary students in public elementary schools in Seoul. A total of 28 items were developed and examined for the internal consistence. The results showed that the proposed scale was appropriate to represent the mathematics anxiety of elementary students. The survey items of this study could be applied for assessing elementary students' mathematics anxiety regardless of their gender and age factors.

스마트 기기에 대한 사용자의 요구사항의 다양화, 고도화라는 키워드를 충족시키기 위해서는 효율성 측면에서 우수한 재조합적 혁신인 컨버전스가 효과적인 방안이다[1]. 사용자의 요구상황을 분석하는 방법으로는 사용자를 관측, 설문을 통한 행위 분석 방법도 있다. 이때 정제되지 않는 관측, 설문, 행위 데이터는 방대한 양이므로 분석하기가 매우 어렵다. 물론 사용자의 데이터 영역을 제한으로 데이터를 줄일 수도 있겠지만 필요한 데이터의 손실 위험을 가지고 있다. 그래서 본 논문에서는 요구사항 데이터를 이용하여 스마트 기기의 컨버전스에 필효한 요구사항 ��루을 위한 분석도구를 제안한다. 적용 사례로 사용자 데이터를 도구를 이용하여 핵심 데이터를 추출하였다. 향후에는 핵심데이터를 가지고 컨버전스된 스마트 기기를 개발할 수 있는 방법을 연구하려 한다.

This study aims to develop a highly-reliable inventory for measuring and analyzing the positive psychological experience in math learning. A measurement result provides meaningful information on the strength of students. Elements of positive psychological experience in math learning were extracted by the extensive research on the literature. The result was verified through the open survey. Through this process, the first preliminary questionnaire of 106 items was released, and was revised into the second one of 66 items through a continuous investigation on reliability and validity. Finally, a measurement inventory with 65 questions for testing 'positive psychological experience in math learning' was established.

This study aims to evaluate of validity and reliability of the job performance tool already developed for the elementary school health teachers. 305 health teachers responded to the questionnaire composed of 50 items. The validity and reliability of the tool were verified by confirmatory factor analysis. That were composed of 8 sub-categories and had 4 factors. The importance, frequency, and difficulty of the four factors were classified according to the questionnaire criteria, but the importance of health promotion is classified as one new item factor. The statistical significance of the fit of the model was 3.664 (df = 246, p<0.001), RMSEA=0.09, NFI=0.85 and CFI=0.88. The internal consistency of the subscales was Cronbach's ${\alpha}$ of 0.88 to 0.96. The internal consistency of the subscales, Cronbach's ${\alpha}$ was 0.88~0.96. This study shows that the analysis tool for primary school health teacher is valid and reliable as a measurement tool.

Objects：This study was carried out to develop the Korean form of Moral Development Inventory for Adolescents designed to assess the principled morality in adolescents. And the auther also intended to find the demographic variables that influence the moral development. Methods：The Korean form inventory was applied to 507 middle and high school adolescents, and retest was done in 42 second year middle school adolescents with 3 weeks interval. Together this inventory, short form of Rest moral development which had been proved its reliability and validity, were administered to the all subjects for concurrent validity. And then the author examined whether this inventory discriminates between conduct disorder patients, psychiatric controls and normal controls in the level of moral development. Results：Test-retest reliability and internal consistency were very satisfactory. Concurrent validity with this inventory was also high level. And conduct disorder patients were scored significant lower than psychiatric and normal controls in the level of principled morality. The mean PM scores did not show significant difference according to the variables such as sex, birth order and religion. But there was significant difference according to the educational level of mother and places. Conclusions：These results indicate that the Korean form of Moral Development Inventory is a reliable and valid rating inventory to assess the moral development level in Korean adolescents.

In this paper, we propose to develop a diagnosis tool for measuring digital competence for university student. To this end, 223 students participated for the survey research. Based on the survey by 6 domain and 40 questions, 6 factors and 18 questions for digital competence measurement were drawn throughout the factors analysis. The results of the confirmatory factor analysis showed the fact that 6 factors and 18 questions that satisfied the model-fit indexes statistically were finally confirmed. And the developed tool demonstrated good results in reliability and validity verification, which were suitable for measuring digital competence for university students. The developed measurement tool of digital competence for university students consisted of 6 sub-components such digital device operation, communication and collaboration, information searching, processing, and management, problem solving and learning, security, digital ethics. The digital competence measuring tool developed in this study is expected to be used to identify the current level of competences for university student, and to enhance their own digital competences through educational supports.
