The work of teachers is tile critical element ill effective shooting. But most reform efforts have focused on tile teaching profession as a whole and effective schools. Only minimal attention has been given to the subset of teachers whose performance is marginal or incompetent, those who undermine the very concept of “educational excellence.” Teachers are the school's primary point of contact with students and, in large part, determine the educational goals and learning activities for students. How teaching is conducted has a large impact on students' abilities to educate themselves, and there is evidence that teacher quality directly affects student learning. Unfortunately, the evaluation of teachers' teaching abilities is not clear, and there are few cases that teachers has correctly feedback fly tile results of the evaluation of their abilities. In this study, we analysized and compared the teacher evaluation systems of Republic of Korea, Russian Federation, and tile United States of America. These results will be based on the improvement of tile systems. In Russian Federation, the highest year of teacher's teaching which affects on teacher's salary is 5. In the United States, it is 12-13 years. But in Korea, it is more than 30 years. That means the teachers who taught for many years are considered as competent teachers in Republic of Korea based on the economic factors of educational effects. In Russia and tile United States of America, teachers' academic backgrounds seriously affect ell teachers' salary. But ill Republic of Korea, teachers' academic background is a bit of a contribution to salary. In Russian federation, teachers' activities related to education, leaking abilities as well as academic background are also affect ell the salary. In Korea, older teachers have more advantages of salary and promotion than younger teachers. Principals and vice principals of Korea have influencing power over teachers because their judgements on teachers play an important part in teachers' promotion. But there is no such power of principals and vice principals in Russia and the United States of America. In Russian federation, the evaluation of teachers abilities is enforced periodically. The results of tile evaluation reflect on teachers' salary directly, After teachers are evaluated, some teachers can earn lower salaries than before. Teachers' academic backgrounds which affect ell teacher' salary are classified by courses. The teachers who have master degrees or dolor degrees of education earn much more money than the teachers who have master degrees and doctor degrees of pure science in Russian federation.

In general, background subtraction based methods are used to detect the moving objects in visual tracking applications. In this paper we employed background subtraction based scheme to detect the temporarily stationary objects. We proposed two schemes for stationary object detection and we compare those in terms of detection performance and computational complexity. In the first approach we used single background and in the second approach we used dual backgrounds, generated with different learning rates, in order to detect temporarily stopped object. Finally, we used normalized cross correlation (NCC) based image comparison to monitor and track the detected stationary object in a video scene. The proposed method is robust with partial occlusion, short time fully occlusion and illumination changes, as well as it can operate in real time.

Emotion regulation has been suggested as a pathway through which personality traits (e.g., extraversion or neuroticism) affect psychological well-being. However, the pathway needs further investigation across cultures due to variations in parts of the relationship reported in recent culture research. With an aim of improving current understanding of the pathway, we investigated the role of emotion regulation mediating the link between personality traits and well-being across two college samples from different cultural backgrounds: Korea and the United States (US). Results of mediation analysis revealed that the extraversion-well-being relationship was fully mediated by the degree to which individuals regulate negative emotions in both Korean and US samples. However, the neuroticism-well-being relationship was partially mediated by emotion regulation in the US sample, while it was fully mediated in the Korean sample. The role of emotion regulation differently functioning across cultures suggests the importance of investigating cultural-specific mechanism of psychological processes.

Purpose: Nursing communication has become more important than ever before because quality of nursing services largely depends on the quality of communication in a very competitive health care environment. This article was to introduce ways to improve nursing communication using conversation analysis. Methods: This was a review study on conversation analysis, critically examining previous studies in nursing communication and interpersonal relationships. Results: This study provided theoretical backgrounds and basic assumptions of conversation analysis which was influenced by ethnomethodology, phenomenology, and sociolinguistic. In addition, the characteristics and analysis methods of conversation analysis were illustrated in detail. Lastly, how conversation analysis could help improve communication was shown, by examining researches using conversation analysis not only for ordinary conversations but also for extraordinary or difficult conversations such as conversations between patients with dementia and their professional nurses. Conclusion: Conversation analysis can help in improving nursing communication by providing various structures and patterns as well as prototypes of conversation, and by suggesting specific problems and problem-solving strategies in communication.

The purpose of this study was to examine elementary teachers' perception on birds and problems on teaching it. For this study, the science textbooks from 3rd grade to 6th grade according to the 7th national curriculum were analyzed. Results revealed that, firstly, there were 34 bird species recorded and these were described 55 times in the surveyed textbooks. Secondly, the survey showed that $20\%$ of the teachers were interested in birds despite the fact that $98\%$ of them had no special knowledge about birds nor had studied them in college. Additionally, it was revealed that $41\%$ of the teachers felt lacking in specialist knowledge about birds and this lead to difficulties in teaching on this subject. Thirdly, academic backgrounds had an affect teachers' perceptions on teaching this area. The teachers' levels of interest in birds and the teachers' ratio of teaching on this topic tended to increase as their academic careers developed, and the proportion of male teachers in this category were higher than female teachers. To overcome difficulty in teaching on this area, it is suggested that a reconstitution of subject materials, as well as a revision of the teachers' guidebooks be undertaken.

The aim of this paper is to review the current knowledge management (KM) practices and their importance in the public sector of Saudi Arabia. Using the term "knowledge management in public sector", a search for available works was done in Google Scholar. In the first stage, the search for literature published under anytime choice was done in the first 10 pages of the search engine. Then another nine pages of Goggle Scholar were searched for more recent works published setting the time as 2014 to 2018. The search yielded 37 usable works for this review. The results of this literature search and review indicated that out of the 37 works reviewed, only three works were related to Saudi Arabia. Number of papers on factors of KM were maximum, many of them giving diagrammatic presentation of their results. KM modelling itself is not easy as only very few papers on KM modelling were available. Problems of too much reliance on qualitative data and hypotheses not matching with the literature backgrounds for them were also found. Considering the works related to KM, the number of papers in various categories may indicate the dimensions of KM to be considered when KM is implemented or evaluated in any public sector of any country. This applies to Saudi Arabian public sector organizations also. There is a fertile ground of research waiting to be investigated by researchers in Saudi Arabia.

Until recently, Pacific equatorial tropical island states were subject of only very limited interest by scientists, government officials, industry and policy makers of Korea. And, comprehensive information and data on these island regions is not very detailed to help better understand their social backgrounds as well as their natural environment. However, these island regions are now in the middle of diplomatic tug-of-war among super powers as well as becoming nucleus of various science-based ocean issues including marine biodiversity, shifting ecosystem, global environmental change including sea level rise and ocean acidification, fisheries, etc. Therefore, rising political and scientific importance of these areas call for better understanding of these regions, in social aspects as well as natural scientific knowledge of the region. To be provocatively prepared to more actively role in these regions, "A study on Establishing Research Infrastructures in the Tropical Pacific" has been supported during 2012-2013 as a mission-oriented in-house project of the KIOST. This project aims to provide various research infrastructure for Pacific island states, to reinforce cooperation with these nations, and to enhance Korea's national prestige. This special issue contains 10 research articles based on the studies conducted in 2012~2013.

Root and shoot development of two rice (Oryza sativa L.) cultivars with different genetic backgrounds was studied with reference to their relative growth. Tongil type (indica-japonica hybrid) cultivar 'Kuemkangbyeo' and japonica cultivar 'Koshihikari' were grown in $5000^{-1}$ a Wagnar pots under flooded condition. Three plants with roots of both cultivars were taken in every phyllochron through the heading stage to record morphological characteristics of shoot and root system. Compared to Koshihikari, Kuemkangbyeo produced more tillers and had greater shoot weight and leaf area per hill. Length and weight of the root system in both cultivars increased exponentially with time. At the same time, root system development was significantly faster in Kuemkangbyeo than in Koshihikari after the panicle initiation stage. As a result, Kuemkangbyeo has a vigorous root system which consists of larger number of nodal roots compared to Koshihikari. Also, the root length and weight per unit leaf area of Kuemkangbyeo were larger than those of Koshihikari in the later half of growing period, which suggests possible higher physiological activity of the root system of Kuemkangbyeo which is known as a high-yielding cultivar. The relationship between root traits (crown root number, total root length, and root dry weight) and shoot traits (leaf area and leaf+culm dry weight) in both cultivars closely showed allometry until the flag leaf stage.
