Although the demand for the use of public data increases in accordance with the expansion of Government 3.0, the poor level of data quality and its management currently implemented is becoming obstacles to opening data to the public. To improve the efficiency of management, linkage and usage for data, standardized processes for data quality management have to be prepared and appropriate data quality assessment criteria should be established. In this paper, we propose the organizational maturity model that can assess the public data quality management level. This model consists of the process reference model and the measurement framework. Fifteen processes grouped by the PDCA cycle are defined in the process reference model. The measurement framework measures the organizational maturity level based on process capability levels. The organizational maturity model can be used to establish objectives and directions for public data quality improvement by diagnosis of current level of public data quality management and problem solving. This model can also facilitate open to the private sector and activate usage of stable public data through reliability enhancement.

This study explored measures to promote the reporting of child abuse, instances of which are increasing year after year. To this end, 16 cases of child abuse, encompassing four instances of each of the four types of child abuse (physical, neglect, sexual, and emotional), were presented to participants to examine whether the perception of each type of abuse affected the degree of its perception as a case of child abuse. Next, the effects of the four types of child abuse on the intention to report child abuse (low vs. high) were investigated in terms of gender (male vs. female) and the construal level. The results revealed that the participants' differed in the intent to report child abuse, depending on varied factors despite the fact that they perceived all cases as child abuse. In particular, no difference was found between men and women in their intent to report child abuse for cases of physical abuse and neglect. However, women exhibited a stronger intent than men to report sexual and emotional abuse. Further, the intention of reporting child abuse was stronger at the high construal level (related to why child abuse must be reported) than it was at the low construal level (concerned with what to do about child abuse). The practical implications of this study include the provision of educational content, the creation of publicity materials that place differing emphases on sex, and the application of low construal level education for reporting child abuse.

The purpose of this study is to examine the experiences and attitudes of elementary pre-service teachers, the level of entrepreneurship core competencies, and to analyze differences in entrepreneurship core competencies by grade, gender, and attitude. To this end, 208 elementary pre-service teachers who responded to the online questionnaire surveyed their experience, attitudes, perceptions, entrepreneurship attempts, and entrepreneurship core competency levels. As a result, pre-service teachers had a low level of understanding and direct participation in entrepreneurship education, the need for entrepreneurship education for elementary school students and teachers was high. The average of the value-creation competency group consisting of innovation, social value orientation, and change agility was relatively lower than the challenge, group creativity, and self-directed competency group. The difference of the entrepreneurship core competency level between the grades was not significant, and female students' competency levels were statistically significantly higher than male students. In addition, the average of the four core competencies of entrepreneurship in the group that recognizes the importance of entrepreneurship as essential competencies was statistically higher than that of their counterparts. Based on the results of this study, the implications for the design and development of a program for enhancing entrepreneurship competency for elementary school pre-service teachers were presented.

The objective of this study was to examine the relationship between physical activity (PA) level and functional fitness (FF) parameters in community-dwelling older adults aged 65 or above in Korea. Subjects' (M: 1,645; F: 2,394) PA level were assessed using a questionnaire. The subjects were divided into two groups: one below the recommended level of PA(LPA) and one above the recommended level (PA). PA was further classified by intensity level into medium- and high-intensity PA (MIPA and HIPA respectively) groups. FF was assessed based on six test items representing the following fitness areas: lower and upper body strength, agility and dynamic balance, flexibility, aerobic capacity, coordination, and body composition. Of the subjects, 36% met the recommended level of PA. Both MIPA and HIPA were superior to LPA in all FF items(p<.05). The HIPA group was significantly better in terms of agility and dynamic balance, coordination, and lower body strength (only in women) than was the MIPA group(p<.05). In conclusion, PA above the recommended level is needed to maintain functional fitness. In addition, HIPA seems to promote fall-related functional fitness and should be encouraged when safe and feasible.

Chemistry is the subject which includes properties, change, and composition of matter. Chemistry has the system which explains observable properties and change with microscopic level, it explains them using scientific theory and laws. In the national-level curriculum, the properties and changes of matter are continuously dealt with from elementary school to high school, and the curriculum are organized so that students could strengthen their understanding about matter. In other words, understanding of the properties and changes of matter is the base to explain everyday life with the view of chemistry, and these two are classified as domains of chemistry in the 2015 revised science curriculum. In this study, we confirmed students' understanding about properties of matter and change of matter, through the analysis about results of the National Assessment of Educational Achievement (NAEA). For that purpose, this study analyzed the 12 items about properties of matter, and 19 items about change of matter, which were used in the NAEA from 2015 to 2019. According to the results of classifying and analyzing questions according to the core concept, the understanding about the two domains significantly changed between the proficient achievement-level students and basic achievement-level students. Depending on the achievement-level, there was a difference in explaining the phenomenon by using the perspective of particles, and by associating scientific concepts and models, or there was a difference in understanding the inquiry related to these two domains. Based on this analysis, this study discussed some implications to be improved on teaching-learning for 'properties of matter', and 'change of matter'.

The purpose of the research was to examine the effect of field of view on egocentric distance perception in the real and virtual environment. The replica that mimicked the real environment condition was used to create the virtual environment condition. We manipulated field of view levels equally in both viewing conditions using glasses that limit the field of view in real-world conditions and limiting the field of view in virtual-world conditions in a manner equivalent to real-world conditions via HMD. Eighteen participants observed the target with a limited field of view in a real and virtual environment without head movement. Then, we measured perceived distance using the timed imagined walking method, which measures the time taken by each participant to mentally walk to the target. The target was shown three times at three different distances from the participants: 3, 4, and 5 m. For the analysis, we converted time estimates into distance estimates. Consequently, the estimated distance in the virtual environment condition was less than the estimated distance in the real environment condition. And as the field of view shrank, the estimated distance also decreased. The estimated distance did not vary with field of view levels in real-world conditions. In the virtual environment, the estimated distance decreased as the field of view decreased, whereas in the real environment, the estimated distance increased. The implications of the results and some future research directions are discussed below.

Korea's port development adjusts the completion time and size of port facilities according to the future port throughput. The current port development system, which is referred to as "throughput-linked port development (Trigger Rule)", has received positive evaluation for efficiently executing the limited port development budget. Recently concerns have been growing over deteriorating service levels in port facilities in Korea due to accelerated aging of terminal facilities. However, the current port development system does not possess any standard for assessing the level of service and utilizing development indicators. The purpose of this paper is to calculate the Port Service Index (PSI) by selecting indicators to measure the Level of Service (LOS) of ports and deriving weights between the indicators, so that the current "throughput-linked port development (Trigger Rule)" can be linked with the level of service. Based on the result of analysis on a variety of preceding studies, the ship waiting rate, berth productivity, ship turnaround time and ship productivity were selected as four indicators to constitute the Port Service Index. The AHP and entropy methodologies were used to derive weights for each of four indicators which were later combined to calculate the comprehensive weight. The calculation formula of the Port Service Index (PSI) was derived by using the aggregated weights of each indicator, based on which the LOS of domestic container and bulk terminals were evaluated and this measurement result was divided into 6 classes to define each LOS. This paper contributes to draw the improvement measures for port development system that are able to connect the quantitative indicator of throughput, as well as a qualitative indicator of the level of "service".

This experiment was conducted to investigate the effects of varying levels of metabolizable energy (ME) and crude protein (CP) on growth performance and carcass characteristics in layer-type growing male chicks. Nine hundred 1-d-old Hy-Line Brown male chicks were randomly allocated to 30 pens in a $2{\times}3$ factorial design. The experimental diets contained 2 levels of ME (2,800 kcal/kg and 2,950 kcal/kg) in combination with 3 levels of CP (17%, 18.5%, and, 20%). A significant interaction of ME and CP on feed intake was observed (p<0.05). No interaction was observed between ME and CP for 53 d BW gain or FCR, which improved linearly with dietary CP levels (p<0.05). A significant interaction or tendency was observed between ME and CP levels. The intake of ME for 1 g BW gain was linearly decreased with increasing CP levels (p<0.001). The intake of CP per bird was significantly increased in low ME (2,800 kcal/kg) treatment than that of the high ME treatment (2,950 kcal/kg) (p<0.05), and dietary CP level had more influence on CP intake for gram BW gain than level of ME. The relative weights of liver, spleen, breast meat and, leg were not influenced by the dietary treatments. Serum BUN, albumin, creatinine, and the activities of GOT and GPT were not influenced significantly by the diet treatment. In conclusion, the growth performance in layer-type male chicks was linearly increased when the level of dietary CP increased. The ME and CP did not affect the carcass characteristics and blood profiles. Therefore, the optimum levels of dietary ME and CP to improve the growth were 2,800 kcal/kg and above 18.5% in layer-type growing male chicks, respectively.

In this study, the test that were used in entrance examination for chemistry class in a Science-Gifted Education Center for middle school students were analyzed by using criteria for identification and measurement of scientific giftedness and a classical test theory. The result of analysis exhibited that most of problems measured more than two elements of scientific giftedness and required applications of scientific knowledge of middle school level to solve problems. In the analysis of sub-elements of scientific giftedness, originality, fluency in creativity and finding problems/formulating hypothesis, planning inquiry, interpreting data in science process skills were dominant while drawing conclusion and generalization processes were lacking. In correlation analysis between total score and each type of problems, total score was most influenced by the problems measuring science inquiry linked with scientific knowledge. Item difficulty is moderately high and item discrimination is moderate.
