This study aims to quantitatively analyze impacts of the team-based learning (TBL) method on learning of architectural engineering students. A TBL-based education program, consisted of preparation, readiness assurance, and application phases, was proposed by considering characteristics of architectural engineering education in South Korea and was applied in building construction classes. In order to measure learning effects and satisfaction levels of the proposed TBL-based education program, a set of questionnaires was conducted with students who took the building construction classes. As the results, learning effects and satisfaction levels of the TBL-based approach were higher than those of traditional approaches. Individual and team readiness assurance tests in the readiness assurance phase were the most effective and satisfactory items, while assessment in the application phase was the least effective and satisfactory item.

The recent studies indicated that the major sources of the failure in carrying out the programs of weapon systems development would be the unsatisfaction of the required key performance and also the use of premature technology. As such, to manage the risk during the weapon systems development, the use of the technical performance measurement (TPM) and the technology maturity assessment (TMA) turned out to be necessary. However, the TPM studied so far seems to cover the assessment of performance at the component level only, and thus is insufficient in considering the system integration effect. On the other hand, the system readiness level (SRL) method has been presented by reflecting the effect on system integration, but the system performance and maturity has not been considered. To overcome this, a measurement method is proposed in the paper by utilizing the combined system readiness level and achieved technical performance at the system level. This system performance measure can be useful in managing the risk in the weapon systems development.

The optical sensors of Electro-Optical Camera (EOC) and Ocean Scanning Multi-spectral Imager (OSMI) aboard the KOrea Multi-Purpose SATellite (KOMPSAT) will be placed in a sun synchronous orbit in late 1999. The EOC and OSMI sensors are expected to produce the land mapping imagery of Korean territory and the ocean color imagery of world oceans, respectively. Utilization of the EOC and OSMI data would encompass the various fields of science and technology such as land mapping, land use and development, flood monitoring, biological oceanography, fishery, and environmental monitoring. Readiness of data support for user community is thus essential to the success of the KOMPSAT program. As a part of testing such readiness prior to the KOMPSAT launch, we have performed the preliminary acceptance test for the KOMPSAT data processing system using the simulated EOC and OSMI data sets. The purpose of this paper is to demonstrate the readiness of the KOMPSAT data processing system, and to help data users understand how the KOMPSAT EOC and OSMI data are processed, archived, and provided. Test results demonstrate that all requirements described in the data processing specification have been met, and that the image integrity is maintained for all products. It is however noted that since the product accuracy is limited by the simulated sensor data, any quantitative assessment of image products can not be made until actual KOMPSAT images will be acquired.

The live fire test has been playing a critical role in evaluating the goals-to-meet of the weapon systems which utilize the power of explosives. As such, the successful development of the test systems therein is quite important. The test systems development covers that of ranges and facilities including system-level key components such as mission control, instrumentation or observation, safety control, electric power, launch pad, and so on. In addition, proper operational guidelines are needed with well-trained test and operation personnel. The emerging weapon systems to be deployed in future battle field would thus have to be more precise and dynamic, smarter, thereby requiring more elaboration. Furthermore, the safety consideration is becoming more serious due to the ever-increasing power of explosives. In such a situation, development of live fire test systems seems to be challenging. The objective of the paper is on how to incorporate the safety and other requirements in the development. To achieve the goal, an architectural approach is adopted by utilizing both the system components relationship and safety requirement when advanced instrumentation technology needs to be developed and deteriorated components of the range are replaced. As an evaluation method, it is studied how the level of maturity of the test systems development can be assessed particularly with the safety requirement considered. Based on the concepts of both systems engineering and SoS (System-of-Systems) engineering process, an enhanced model for the system readiness level is proposed by incorporating safety. The maturity model proposed would be helpful in assessing the maturity of safety-critical systems development whereas the costing model would provide a guide on how the reasonable test resource allocation plan can be made, which is based on the live fire test scenario of future complex weapon systems such as SoS.

This study examined how early maternal language use was associated with school readiness at kindergarten entry among children of Asian or Hispanic immigrant mothers in the United States. Using a nationally representative sample from the Early Childhood Longitudinal Study-Birth Cohort (ECLS-B; $N{\approx}1,500$), this study estimates multivariate regression models to address each research question. This study finds generally advantages of maternal use of English and bilingualism for children's expressive language in both Asian and Hispanic groups and for children's pro-social behavior in the Asian group. It also finds that longer residency in the U.S. is associated with higher levels of approaches to learning for children of bilingual Asian mothers and lower levels of behavior problems for children of bilingual Hispanic mothers. Based on the findings, social work implications for the healthy development of young children of immigrants were discussed.

This study was conducted for nursing students to identify the effects of professors' teaching skills, learners' online learning readiness and major satisfaction on the online learning satisfaction after the COVID-19 pandemic. The participants recruited from nursing colleges located in five province, and data was collected using the Google Online Questionnaire from August 17th to October 5th, 2020. A total of 130 data were analyzed using the SPSS 23.0 program. As a result of this study, the factors that affect online learning satisfaction are the methods in the teaching skills (β=.43, p <.001) and self-directed learning in the online learning readiness (β=.33, p <.001), and satisfaction in nursing major (β=.21, p <.001). The results of this study suggest that education methods need to be devised to enhance the satisfaction of online learning in nursing colleges, and environmental improvements that can be self-directed learning are needed.

This study analyzed the effects of optimism and innovativeness, the two drivers of a consumer's technological readiness to use an augmented reality(AR) fashion shopping service within the framework of the Technology Acceptance Model (TAM). The survey was conducted on 249 people (males = 58; females = 191) in their 20s who were willing to participate in the AR experience. Data were analyzed using confirmatory factor analysis (CFA) and structural equation modeling by AMOS 22.0. The results indicated that a greater level of perceived optimism had a positive influence on the ease of use and usefulness of the technology. The findings also show that consumers with a high degree of innovativeness tend to have a higher level of playfulness toward AR fashion shopping. Regarding the effects of user beliefs, ease of use had a positive effect on the perception of usefulness and playfulness with higher levels implying a higher consumer intention to adopt an AR fashion shopping service. In addition, this study reveals the moderating effect of consumers with high-fashion versus those with low-fashion innovativeness. For the latter, technological innovation had an insignificant effect on playfulness, thus indicating that consumers with low interest in fashion did not enjoy AR fashion shopping even if the technology was highly innovative. Nevertheless, the analysis confirms the possibility that experiencing a fashion product through AR technology could replace the actual experience of wearing the products.

Digital services improve existing ways of purchasing contracts. In this study, we empirically analyzed the effects of individual technology readiness (optimism, innovation, inconvenience, anxiety) on the acceptance intention of cloud computing technology for users with relatively high understanding of cloud service. Also, the effect of technology readiness on acceptance intention was verified by the mediating effect of digital conversion. As a result, optimism and innovation had a positive effect on digital conversion, and discomfort and anxiety had a negative effect on digital conversion. And although the partial mediating effect of digital conversion was verified in the relationship between optimism, anxiety and acceptance intention, it was verified that there was no mediating effect of digital conversion in the relationship between innovation, discomfort and acceptance intention. Through these results, the practical implications and future research directions of cloud services were presented to companies.

Analyzing the psychological and pedagogical literature, we showed the interest of researchers in the problem posed. The concept of competence is considered, which is interpreted as giving the key to solving a wide range of educational and life tasks. Research competence implies the ability to cooperate, enter into contacts, readiness for changes, for self-determination and is an integral quality of the individual, expressed in the readiness and ability to independently search for solutions to new problems and creative transformation of reality based on a set of personal and meaningful knowledge, skills, methods of activity and value attitudes.The article offers conditions that certify the improvement of forms and methods of training students in the formation of research competence of future specialists. The use of innovative technologies contributes to improving the level of training of future specialists: students are better prepared for classes, take an active part in the assimilation of program material in laboratory classes. It is noted that this creates a subject-subject relationship between the student and the teacher, and changes the attitude of students to classes. In the process of such organization of educational activities, students are convinced of the need for knowledge and its effectiveness, learn to compare, generalize, classify, establish cause-and-effect relationships, express opinions, defend their point of view, they ensure success in their studies, and develop research competence. It is proved that in order to apply the latest technologies, the teacher himself must know them well, that is, constantly improve himself, master new methods, techniques, ideas, which will help him create new pedagogical technologies and implement them in the educational process.
