The purpose of this study is to explore a budget-securing strategy to enable archival professionals in public institutions to continuously secure the budget for records management projects. This study is an analysis of the results of in-depth interviews with 14 archival professionals who have worked for public institutions and secured budgets for records management projects. As a result of the analysis, 4 upper categories and 10 categories are extracted as factors influencing budget securement. The top four categories are the job environment of archival professionals, umbrella organization and organizational culture, business and budget characteristics, and system and social environment. As the budget-securing strategy for archival professionals, a total of 3 categories and 13 strategic codes are derived. The three categories are utilizing individual-centered competencies, establishing organization-centered relationships, and finding external environment-centered triggers. This study emphasized the perspective of archival professionals and suggested implications such as the role of archival professionals and the direction of improvement in securing budgets.

With isogenic waxy and non-waxy rice cultivars, growth responce as affected by leaf-removal treatment were examined in various fertilizer application. Vertical dry matter of culm was significantly decreased from ground upto 10cm. Culm dry matter of waxy rice was more steadily decreased than that of non-waxy rice. Starch content of culm in non-waxy rice was higher than waxy rice, and that in waxy and non-waxy rice were the lowest in three leaf-removal but no difference in single leaf-removal. Flag leaf in waxy rice and 2 nd leaf in non-waxy rice were dominantly affected yield by leaf-removal. The 1000-grain weight and rippend grain ratio of non-waxy rice were more higher than waxy rice and that in waxy and non-waxy rice were the lowest value in three leaf-removal but no difference in single leaf-removal treatments.

This study aims to analyze the changes in the management efficiency of public institutions in time series, and to examine the relationship with financial performance based on the results of time series changes. Specifically, we classified into upper and lower groups of financial performance based on the government's management evaluation results, and analyze how the management efficiency of each group changed in the period before the evaluation year. Based on public institutions published in public business information system, DEA(Data Envelopment Analysis) was performed for estimating management efficiency. The results are summarized as follows; First, we find that DEA of the upper group changed in the direction of increasing, but DEA of the lower group changed in the direction of decreasing. Second, we find that there is a significant positive relation between DEA and financial performance. This result means that the higher financial performance, the higher management efficiency. These findings imply that management efficiency can be a factor that improve financial performance in public institutions. The results also suggest that government's innovation strategies to improve financial stability by enhancing management efficiency were effective.

Mathematical, verbal, and spatial abilities are known as three important indicators for the success in the STEM disciplines. In this study, Purdue Spatial Visualization Test-Rotation, College Entrance Scholastic Aptitude Test- Math and Verbal score of engineering freshmen students have been used to find the relationships among these areas. In addition, gender differences in spatial visualization, verbal achievement and mathematical achievement have been investigated, too. In this research, I found that gender difference was highest in spatial visualization ability, followed by verbal achievement and smallest in mathematical achievement. Substantial number of male students possess high level of spatial abilities, but only half of female students were at the same level where their male colleagues were. The correlation between spatial ability and mathematical ability was negligible, contrary to former researches on elementary and middle school students. But the correlation was stronger for female students than male students. The correlation between mathematical achievement and verbal achievement was negative. It reflects the fact that when one section of SAT score is low, score of other sections should be higher to get admitted to college. Gender difference in mathematics was smallest for high achieving spatial ability group. For low spatial ability group gender difference in mathematics achievement has been observed, too. To find the combined contribution of spatial and verbal abilities to mathematics achievement, students were divided into 4 ability groups. Mathematics achievement decreased in the order of (1) high spatial -low verbal group, (2) low spatial - low verbal group, (3) high spatial - high verbal group, (4) low spatial - high verbal group.

This study surveyed 60 early childhood teachers at the kindergartens and day care centers in Incheon Metropolitan City to examine the contents and extent of the teachers' knowledge on early childhood history education by using the definition map designed by Novak and Gowin(1984). To be more specific, the researcher asked the participating teachers through group meetings to draw the definition maps and analyzed them. The results were as follow. First, 11 categories for high level definition of early childhood history education used by early childhood education were identified, among which the most frequently used high level definition were 'life style' followed in order by 'culture/art' and 'great men.' Second, in terms of the average number of dependent definitions included in the given high level definitions, the largest was 'life style' which was followed in order by culture/art, activity methods. It means that the widest area of early childhood teachers' knowledge on early childhood history education was about 'life style,' while it shows that the extent of knowledge on teaching-learning methods was relatively wide. However, in the case of great men, although it was frequently recognized in the high level of definition it was not so in the dependent definitions, meaning the extent of their knowledge was rather narrow. Scholars explain that the higher the teachers' attention and knowledge about the content of curriculum the more options of teaching method they tend to employ to teach in a more extensive and diverged way. Therefore, in order to improve early childhood education, efforts should be more focused on deepening and systemizing the knowledge of early childhood teachers.

The domestic AI speaker market is growing into a full-fledged early audience market beyond the innovative consumer market with 3 million domestic supply units at the end of 2018, but the reality is that for various reasons, we are not satisfied with the use. There are many previous papers on AI Speaker, but the majority of research so far tends to be biased towards the acceptance of the device's own performance. Many changes are being made, such as OTT providers trying to secure the market through collaboration with AI speaker providers. This study tried to identify the priorities for content services, which can be another major selection factor for AI speakers, excluding the factors of unsatisfactory technology. First, this study identified the priorities among AI speaker selection factors using AHP (Analytic Hierarchy Process), based on the AI speaker selection factors derived through literature research. The most important hierarchical factor are Concierge Service, Education Service, and Entertainment Service order in AI speaker selection, and the primary content among the individual factors was the one that ranked weather/temperature/fine dust (11.6%) and child caring content was in the second place (10.8%), and then music service was in the third place (9.8%). The three top priorities were derived from the items in the top tier 1, 2 and 3 priorities. Of the total 15 individual services, 6 sub-layers of Concierge Service (weather/temperature/fine dust, news, voice schedule notification) and Education Service (foreign language, toddler, reading books) were in the top 8, and two of the Entertainment Service Music service and movie service ranked third and sixth.

HEVC (High Efficiency Video Coding) achieves high coding efficiency by employing a quadtree-based coding unit (CU) block partitioning structure and various prediction units (PUs), and the determination of the best CU partition structure and the best PU mode based on rate-distortion (R-D) cost. However, the computation complexity of encoding also dramatically increases. In this paper, to reduce such encoding computational complexity, we propose three fast PU mode decision methods based on encoding information of upper depth as follows. In the first method, the search of PU mode of the current CU is early terminated based on the sub-CBF (Coded Block Flag) of upper depth. In the second method, the search of intra prediction modes of PU in the current CU is skipped based on the sub-Intra R-D cost of upper depth. In the last method, the search of intra prediction modes of PU in the lower depth's CUs is skipped based on the sub-CBF of the current depth's CU. Experimental results show that the three proposed methods reduce the computational complexity of HM 14.0 to 31.4%, 2.5%, and 23.4% with BD-rate increase of 1.2%, 0.11%, and 0.9%, respectively. The three methods can be applied in a combined way to be applied to both of inter prediction and intra prediction, which results in the complexity reduction of 34.2% with 1.9% BD-rate increase.

Two cultivars which are glutinous (Hawcheongchalbyeo) and non-glutinous (Hawcheongbyeo) near isogenic line of rice, were used for this study. The objective of this experiment was to gain the basic information for increasing grain yield of waxy rice by means of source and sink size control. In both Hwacheongbyeo and Hawcheongchalbyeo, the trend of decrease in total and average spikelet weight was ranked as follows; removal of penultimate leaf＜ removal of flag leaf＜ removal of flag leaf and 3ya leaf from the top ＜ removal of flag leaf and penultimate leaf ＜ removal of flag leaf, penultimate leaf, and 3rd leaf from the top. The reduction yale of total and average spikelet weight per panicle of Hwacheongbyeo was higher than those of Hwacheongchalbyeo according to the removal of flag leaf, penultimate leaf, and 3rd leaf from the top. In both cultivars, high-density grain ratio and grain filling ratio of the primary branches were higher Hun those of the secondary branches by leaf clipping treatment. The spikelet number and total spikelet weight per pinicle in both Hwacheongbyeo and Hwacheongchalbyeo were decreased by removal of spikelets on branches compared with control, whereas average spikelet weight and grain filling ratio were increased. The increase rate of average spikelet weight of Hwacheongchalbyeo was much higher than that of Hwacheongbyeo by sink size control. High-density grain ratio by removal of spikelets on branches was higher in Hwacheongchalbyeo, but filled grain ratio was higher in Hwacheongbyeo.

Objectives: The purpose of this study was to evaluate the difference of cognitve function among patients with posttraumatic stress disorder according to severity of symptoms. Methods: The subjects were 90 psychiatric inpatients and outpatients with posttraumatic stress disorer(by DSM-IV criteria) after traffic accident. The severity of symptoms was assessed by MMPI subscales; depression, psychasthenia, schizophrenia. The impairment of cognitive function was assessed by Korean Wechsler Intelligence Scale(K-WAIS). Based on scores of the MMPI subscales, the patients were divided into high group(above 70 percentile) and low group(below 30 percentile). We estimated the difference of the K-WAIS score and subtest score in the low group and high group of the MMPI subscales by indedpendent t-test. Results: The scores of high group is significantly higher in the subtests of information, vocabulary, similarity, picture completion, and picture arrangement than the low group for psychasthenia subscale of MMPI. And the score of high group is significantly higher in full scale I.Q., verbal I.Q., performance I.Q., verbal subscales except digit span and simiarity, and performance subscales than low group for schiozphrenia subscale of MMPI. Conclusion: It was found cognitive function was more impaired in the group of PTSD with severe symptom compared to the group of PTSD with mild symptoms. We suggest that psychiatrist should consider various cognitive approaches as well as pharmacotherapy in the management of PTSD.
