Organizational culture provides organizational members with identity, homogeneity and behavioral guidance, and promotes organizational commitment and enhances the stability of social systems. What organizational culture positively influences organizational performance? In this study, we tried to categorize organizational culture as creativity, change, cooperation, trust and knowledge sharing for specific public institutions and to diagnose the organizational culture by examining the level of recognition of the organizational members. The purpose of this study is to investigate the effect of organizational culture on organizational culture. The result of this study shows that the degree of future - oriented and cooperative culture of the public institutions that are the subject of research is not so high. In order to improve the performance of the organization, it is necessary to create a futuristic and cooperative culture. In order to create such a culture, various efforts must be made to continuously communicate and build trust among the members of the organization. In particular, leadership efforts to distribute, transfer, and trust authority to subordinates are a priority. In other words, it is very difficult to build a future-oriented, collaborative culture successfully without the efforts of managers.

The purpose of this study is to analyze components of conflicts and investigate causes of them between mentor teachers and mentee teachers, who participated in the collaborative mentoring program to improve beginning science teachers teaching practice. The most often occurring component of conflict for surveyed teams was class strategy on knowledge of teaching methods. Then, conflicts in understanding student characteristics as a component of understanding students and knowledge transfer of concepts in science as a component of teaching contents followed as main causes. Changes in conflicts showed that less frequency of conflict occurred with ongoing mentoring. Conflicts from class strategy decreased the most, which had been the most often occurring cause. This decrease was explained as mentees were changed gradually into the teacher's role recognition through continuous mentoring. This study suggests that education for mentor and mentee teachers be provided with consideration of causes of conflicts and reasons for those causes, which eventually lead sustainable and efficient mentoring program management.

Due to the characteristic that early childhood education is a process of nurturing children's senses by a leader rather than the transfer of knowledge, even in the era of with Corona, early childhood distance education is not one-to-one non-face-to-face education, but rather through distributed materials such as early childhood education packages or media such as TV. Distance education was conducted in a self-care method. Through a review of prior research and intensive parent interviews, the researcher identified the requirements for distance education, such as the expansion and accessibility of educational contents, understanding of basic knowledge of early childhood distance education, and the need to increase children's social skills through real-time distance education. It was identified that the current distance education-related solutions are not suitable for early childhood education. Accordingly, the researcher presents the basic direction (VERI) of the early childhood distance education solution of diversity, ease, real-time communication, and integration, and provides a Web/App platform that allows children, parents, and teachers to share content and communicate in real time and in non-real time. The development of a solution was proposed. This distance education solution is expected to effectively support early childhood distance education in the era of With Corona as infants, parents, and teachers communicate and share the current situation, which is only presenting guidelines and materials.

Computer and Internet information technologies(ICTs) have changed the modern service industry and people's life style. In particular, the global spread of COVID-19 has attracted more attention to contact service types such as self-service technology. With the increase in labor costs and the enhancement of consumer self-awareness, more and more companies transfer part of their work to customers through their own service technology. This study seeks to answer the following questions. (1) Do technology difficulty and safety perception affect customer value recognition in the self-service technologies? (2) Does customer value recognition influence the intention to use such technologies continuously? This study conducted an empirical analysis with 327 samples to validate the influence of self-service characteristics(technology difficulty and safety perception) on customer value recognition and continuous utilization intentions. Also, it analyzes the moderating effects of age and frequency of use on the relationship between self-service characteristics and customer value recognition. The study results show that the technology difficulty does not affect the customer's perceived value recognition; and the higher the customer's value recognition, the higher the intention of continuous use.

This study focused on characterizing various factors in order for learners to maintain their interests in learning and to maximize learning effects as the top priority purpose of university e-Learning, on the basis of results of conceptual studies on existing e-Learning and practical studies, and then on examining them practically. It also analyzed which factors would have greater influence on learning effects of e-Learning in general. Moreover, in comparison with existing numerous studies which examined only factor such as learning effects of e-Learning, it analyzed such things in detail according to division into three items such as learning satisfaction, learning transfer and learning recommendation. To achieve such purposes of the study, it characterized and set 3 factors such as learning contents, instructional design and user convenience on the assumption that such factors have a significant influence on learning effects of e-Learning. Moreover, the factor of learning contents includes 3 detailed elements, i.e., learning issue and objective, knowledge information, and consistency and propriety, and the factor of instructional design includes 4 detailed elements, i.e., interest and sympathy, interaction, contents presentation and explanatory strategy. Lastly, the factor of user convenience includes 2 detailed elements such as screen configuration, and check-up of contents and teaching schedule. According to analytical results, it showed all 3 factors such as learning contents, instructional design and user convenience have a significant influence on learning effects of e-Learning(i.e., learning satisfaction, learning transfer and learning recommendation). In more detail, it showed the learning issue and objective from the factor of learning contents have the greatest influence on learning satisfaction of e-Learning. Then, it is the most important to set the learning issue and objective with given priority to learners and set the learning objective estimable, in order to raise the learning satisfaction. It showed the contents presentation from the factor of instructional design on the learning transfer. Therefore, it is the most important to structuralize mutual relation and presentation orders to promote learning systematically and to let learners access to such things, for the purpose of raising the learning transfer. Moreover, it showed the interest and sympathy from the factor of instructional design has the greatest influence on the learning recommendation. Thus, it is the most important to promote learners' interests to the maximum using well-timed media, and to give a lecture enough to arouse learners' sympathy.

The purpose of this study is to investigate beginner and experienced Korean science teachers' perceptions about the science teacher preparation courses from which they graduated, and to compare them. The study was conducted as a qualitative study using in-depth interviews. For the study, interview questions were developed by the authors based on the questionnaire of 'The IMPPACT project' that was being conducted in America. The interview tool includes questions about their experience of science subject matter content knowledge, science pedagogical content knowledge, and general pedagogical content knowledge in their preparation courses. For the interview, seven beginning science teachers, less than five years of teaching experience, and five experienced science teachers, more than five years of teaching experience, were sampled from secondary schools in Korea. The research results are as follows: First, most of the beginner and experienced science teachers perceived that the teaching methods in the classes of science subject matter were not good model for teaching science in their secondary school, because they were not diverse enough and entailed mostly knowledge transfer just through lecture without teacher-student interaction. Second, most of the beginner science teachers perceived that they were affected positively by the teaching strategies and evaluation methods in the classes for science pedagogical subject matter and they could apply those strategies and methods in their current science teaching. Lastly, most of the beginner and experienced science teachers perceived that general pedagogical subject matter is important and prerequisite for science teaching in their schools, but the courses that they experienced at their university were not appropriate for their current teaching.

Fish larvae are immediately exposed to microbes from hatching to maturation of their lymphoid organs, therefore effective innate mechanisms is very important for survival. However, the knowledge of the development of immune system in fish is limited and in demand now. In vertebrates, recombination-activating gene 1 (RAG-1) and immunoglobulin M (IgM) have been considered as very useful markers of the physiological maturity of the immune system. In this study, the expression of the both genes was assessed throughout the early developmental stages of olive flounder larvae (5-55 dph) and used as markers to follow the development of immune system. RAG-1 and IgM mRNA expression was detectable at 5 dph and remained so until 55 dph. These patterns of expression may suggest that the olive flounder start to develop its function around 5 dph. Tissue distribution was found that both genes mRNAs are only expressed in the immune-related organ such as spleen, kidney and gill. The early detection of IgM mRNA led to the investigation of its presence in oocytes. Both RAG-1 and IgM mRNA transcripts were detected in unfertilized oocytes, suggesting that they are maternally transferred. The biological significance of such a phenomenon remains to be investigated.

The role of foreign direct investment (FDI) as a channel of knowledge transfer and on the technological spillovers of know-how to other sectors in the economy is in the middle of this debate. Thus, foreign direct investment may have significant positive effects in reducing residual loadings and environmental pollution. There is an abiding concern expressed by many commentators that countries will lower their environmental standards to attract foreign investment, thereby creating so-called "pollution havens." Others argue that increasing foreign investment could promote "pollution halos" by introducing and transferring more efficient and less polluting technologies. The primary objective of this study is to show the dynamic relationship among pollution loadings, pollution abatement effort, and economic development with explicit consideration of FDI-related effects. This study found when foreign direct investment is evaluated in the model, the environmental pollution level is reduced and expenditure on pollution abatement is increased.

2-mass system is generally used as controller of the variable-speed to transfer electromotion power to mechanical load such as industrial robot, driving parts of electric vehicle, rolling machine system of steel plant and driving parts of elevator. In this case, PI controller is often used as a velocity controller because of simplicity of system. But PI control algorithm is not enough for obtaining the control characteristics required for this system. To solve this problem, 2-mass system based on the PID controller derives the optimum PID parameters by pole assignment and estimation of the ITAE performance index. In this case, the system have tenacious properties about disturbance, but it causes extreme overshoot and vibration because of rapidly output of controller in early transient response about desired value. And if speed control system is applied by 2-DOF parameter ${\alpha}$, a temporary value, we must induce most suitable parameter by complicate pole assignment and estimation of the ITAE performance index whenever ${\alpha}$ changes. In this paper, to solve this problem we suggest control algorithm to followed exactly value of ${\alpha}$ as 2-DOF parameter by using fuzzy algorithm . So, intelligence algorithm modeled by human knowledge, experience, teachability and judgment follow exact ${\alpha}$ value and it can compose the efficient 2-DOF PID controller to improve following performance, overshoot decrease.

In 1961, the Republic of Korea's first newly-constructed government building was completed. The government building, as ROK office, was erected as a twin with the USOM office in Sejong-ro. The reason why the ROK office and the USOM office were erected as a twin building is that the two offices were part of Foreign Operation Administration's Seoul Buildings Project in 1954. Within the project, the FOA office and the ROK office were rarely separated, and naturally, the ROK office was built according to the US standards. The planning, design, and construction phases which led by the US government were involved in the US architecture, engineering-construction companies. Because those AEC companies were familiar with the US technology and standards. In the phase of construction, Korean companies took part in the process under the supervise of Vinnell Corporation. The US expected to transfer its 'modern' and 'developed' technology through this process. The completed ROK office was widely known as the 'modern style (hyundae-sik)' building, which was body forth as glasses and new facilities. These factors were what the US emphasized for exporting architecture. The modifier, 'modern style (hyundae-sik)', given to the ROK office in the 1950s was a synonym for any new feeling that had never been seen hitherto. The newness of the ROK office, the 'modern style (hyundae-sik)' building, was specified as materials and facilities that indicates modern technology while in the absence of adequate knowledge.
