Purpose This study aims to develop a job model for data convergent talents to meet the rapidly changing demands of the data industry. To create a job model, we first define and categorize data convergent talents with balanced competencies in data technology and domain knowledge, and then develop a job model by investigating job areas, scope, activities, and competencies. Design/methodology/approach The research is conducted using the following procedures and methodology. First, we conduct a current status survey on data talent demand, data talent policies, data talent programs, and curricula at home and abroad; second, we collect opinions on the jobs and competencies required for data convergent talents and curricula for talent development through in-depth interview with experts; and third, we present the job areas and job activities of data convergent talents derived from the previous status survey and expert opinions based on the National Competency Standards(NCS). Findings The research findings indicate that there are total of six job roles for data convergent talents, including data scientist, data planner, data architect, data developer, data engineer, and data analyst. It was observed that each of these roles requires the development of common competencies within their respective fields, followed by a need for further specialization into specific competencies within each professional domain.

This study analyzes space resection and space intersection for terrestrial convergent photos taken on the straight line and the circular line by collinearity condition. The purpose is to investigate the properties of convergent case, and to suggest the optimum angle of convergence. Accuracies at convergent angles less than 20$^\circ$ are lower than those in normal photos, but by changing from 20$^\circ$to 90$^\circ$ the accuracy is improving with the highest at 90$^\circ$ convergence. Also, convergent photos on circular line is far higher than those on straight line in accuracies of results, therefore it is expected to apply this results effectively for precise analysis of various facilities.

This study examines network compositions of convergent research relationships in the field of high-tech convergence technology and investigates the relational linkages among various research fields. A network analysis was performed to evaluate the High-Tech Convergence Technology Development Program, a convergent research funding program of the National Research Foundation of Korea (NRF); the dataset covered the 2009-2011 period. The analytical results reveal the hidden network structure of convergent research relationships and demonstrate that the formation of convergent research might be enhanced by interdependent pressures placed on various research fields but also by accumulated research capabilities that each of these fields possessed and which could be used to converge specialized and heterogeneous research areas and interests.

The World Health Organization (WHO) has declared the coronavirus disease 2019 (COVID-19) as an international health emergency. Current diagnostic tests are based on the reverse transcription-quantitative polymerase chain reaction (RT-qPCR) method, which is the gold standard test that involves the amplification of viral RNA. However, the RT-qPCR assay has limitations in terms of sensitivity and quantification. In this study, we tested both qPCR and droplet digital PCR (ddPCR) to detect low amounts of viral RNA. The cycle threshold (CT) of the viral RNA by RT-PCR significantly varied according to the sequences of the primer and probe sets with in vitro transcript (IVT) RNA or viral RNA as templates, whereas the copy number of the viral RNA by ddPCR was effectively quantified with IVT RNA, cultured viral RNA, and RNA from clinical samples. Furthermore, the clinical samples were assayed via both methods, and the sensitivity of the ddPCR was determined to be equal to or more than that of the RT-qPCR. However, the ddPCR assay is more suitable for determining the copy number of reference materials. These findings suggest that the qPCR assay with the ddPCR defined reference materials could be used as a highly sensitive and compatible diagnostic method for viral RNA detection.

Converging technologies have become a major issue in science policy. This paper describes the current state of scientific collaboration for convergent technologies among researchers in South Korea, by conducting Social Network Analysis (SNA) with the data set of 1,095 researchers who have involved in the development of the convergent technologies. It is found that the researchers in convergent technology are more productive than the researchers in other technology domains. However, the researchers in convergent technologies have small number of collaborators, compared with their productivity. Only a few researchers have a role of the hub in the collaboration networks, meaning that the structure network is closer to than the core than the peripheral. The scientific collaboration network of the convergent technology researchers shows that the members of the network are close to each other, but there is small number of cliques.

The purpose of this study is to provide useful information by analysis on mathematic classes for improve interactions between teacher and student using the Flanders Category System. For this, mathematic classes were observed by videotapes and recorded, 10 recorded videotapes were selected for analysis the property of linguistic interaction. The collected videotapes and records materials were transcribed by Advanced Flanders(AF) analysis program version 3.54. The detail investigated topics for studying are as follows. 1) What is the property of the Flanders 10 code analysis results? 2) What is the property of main and subsidiary linguistic flow of interaction? 3) What is the property of the Flanders index analysis results? The results of this study are as follow: 1) In Flanders 10 code analysis results, teacher's non-directive speaking is 12.76%, teacher's Indicative speaking is 50.28%, student's reactive speaking is 4.07%, student's voluntary speaking is 9.66%. 2) Among the 10 classes, 5 classes' main flow is 'ask convergent question ${\rightarrow}$ student's reactive speaking ${\rightarrow}$ lecture ${\rightarrow}$ ask convergent question', 2 classes' main flow is 'lecture ${\rightarrow}$ ask convergent question ${\rightarrow}$ student's reactive speaking ${\rightarrow}$ lecture', 3 classes' main and subsidiary flow is 'lecture ${\rightarrow}$ ask convergent question ${\rightarrow}$ lecture ${\rightarrow}$ work'. 3) In indices results, revised I/d ratio, student's speaking ratio, student question, wide answer ratio are higher than analysis standard and indirect ratio, teacher's question ratio are lower than analysis standard.

To treat a kind of nail damage, this study proceeded with gel polish procedure oriented to 19 women in their twenties and thirties, dividing into three experimental groups, such as the A group with non-treatment (n=6), the B group taking Nutritional Convergent supplement (n=6), and the C group simultaneously taking Nutritional Convergent supplement and Nail Convergent Strengthener (n=7), and inquired into the superficial change of nails, changes of thickness, analysis of damage degree and satisfaction rate. The analysis shows that the C group simultaneously applied with dietary supplement and complex nail supplement presented the best result in all areas. As for the morphological changes of the surface of nails measured by the scanning electron microscope, there were definite changes as compared with the B group. According to the result, it is proved that complex dietary supplement helps to improve the thickness and the surface of damaged nails and it is reasoned that a higher effect can be expected when complex nail supplement is simultaneously used.

Application field of neutron beam is very broad including industry, medicine and science. But the research and development and use of neutron beam is restricted within in narrow limits in this country, because neutron beam facility is insufficient - a big research facility of nuclear reactor(HANARO) and some small industrial facilities which use radioisotope neutron source are available. This paper compare and investigate the results of experiment and numerical analysis of the discharge in the spherically convergent beam fusion device which were expected as a portable neutron source. The spherically convergent beam fusion device will offer stability in neutron production, possibility of movement for convenience, low construction cost and higher neutron flux than radioisotope neutron source. The star mode discharge which efficiently generate neutron, were observed at both results.

The study was conducted to develop two parallel short forms for the Convergent thinking and Problem solving questionnaires which are part of H University's core competency diagnostic tools, based on Multi-Item Response Theory. Item responses of 2,580 students were analyzed using Graded Response Model(GRM) to determine item difficulty and discrimination of each item. The research results are as follows. Two parrallel short tests were developed for the Convergent thinking questionnaire consisting of 12 items which were originally 17 items. Likewise, the Problem solving questionnaire, which originally consisted of 15 questions, was divided into two parallel short forms, each consisting of 9 items. The reliability of the shortened parallel tests was confirmed through internal consistency analysis, and their similarity to the original tests was established through correlation analysis. This study contributed to quality management of competency-based education and programs at H University by developing shortened tests. Based on the results, implications were presented as well as limitations and discussions.

This study examined replication of the factor structure of the DAPC [Domain-specific Assessment of Psychological Control (Soenens et al., 2006)] in parents of Korean adolescents. Participants included 289 adolescents who responded to DAPC items regarding their parents' psychological control behaviors. Two factors comprising 17 items were identified and labeled as "achievement oriented psychological control", and "separation-anxious psychological control." Confirmatory factor analysis and partial correlation analysis provided evidence for the construct validity of the DAPC through construct reliability, convergent validity and discriminant validity across both sex of parents and adolescents. The psychometric properties indicated that DAPC could be useful in studying parents' psychological control behaviors toward their adolescent children.
