In OLED (Organic Light-Emitting Diode) manufacturing, the aging process increases the manufacturing efficiency and measures the correction value to correct the aging. The correction value for correcting the aging of the OLED can be applied to the driving signal. The OLED aging process measures the current after outputting the light for a predetermined time according to the preset driving signal and temperature. In the OLED manufacturing process, aging is applied for non-uniformity by deposition and temperature. This time has little effect on OLED efficiency reduction. Heating devices and signal generation systems are required to create the conditions necessary for aging. The results measured by the heating system and signal generation system can be used as a basis for evaluating power requirements, uniformity and efficiency in OLED manufacturing. In this paper, we propose and implement a configuration for interlocking the driving signal generation and heating system for practical OLED aging correction.

Data generated by the development of ICT, the diversification of ICT devices and services and the expansion of social media are categorized as big data characterized by the amount, variety and speed of the data. The spread of the use of big data is expected to have the effects of identifying the status quo by analyzing data in all industries, predicting the future, and creating opportunities to apply it. However, while it is imperative for these things to be done, the nation still lacks professional training institutions or curricula. In this case study, we will investigate and compare the state of education for the training of big data personnel in Korea, find out what level and level of education is being trained to nurture balanced professionals, and prepare an opportunity to think about how it can help students create value at a time when the need for education is growing in the wake of awareness of big data.

Creating an artificial strain with a minimal gene set for a specific purpose is every biologist's dream. With the complete genome sequencing of more than 50 microorganisms and extensive functional analyses of their genes, it is possible to design a genetic blueprint for a simple custom-designed microbe with the minimal gene set. Two different approaches are being considered. The first 'top-down' approach is trimming the genome to a minimal gene set by selectively removing genes of an organism thought to be unnecessary based on microbial genomics. The second 'bottom-up' approach is to synthesize the proposed minimal genome from basic chemical building blocks. The 'top-down' approach starting with the genome of a well known microorganism is more technically feasible, whereas the bottom-up approach may not be attainable in the nearest future because of the lack of the complete functional analysis of the genes needed for a life. Here in this study, we used the top-down approach to minimize the E. coli genome to create an artificial organism with 'core' elements for self-sustaining and self-replicating cells by eliminating unnecessary genes. Using several different kinds of sophisticated deletion techniques combined with a p:1age and transposons, we deleted about 19％ of the E. coli genome without causing any damages to cellular growth. This smaller E. coli genome will be further reduced to a genome with a minimal gene l;et essential for cell life. This minimized E. coli genome can lead to the construction of many custom-designed strains with myriad practical and commercial applications.

We investigated 8th grade science textbooks and their instructor's manuals treating the ideal condition for isochronism of a simple pendulum. The isochronism, i.e. the period is independent of amplitude, is satisfied only if the amplitude is very small. This is so called "ideal condition" for isochronism of a simple pendulum. Most textbooks and instructor's manuals are found not to state this ideal condition properly, which often leads to the deviation between experimental data and theoretical calculation. This difference between theoretical and experimental results makes students to create a sense of alienation from the real world and eventually keeps them away from physics. We thus study the cycloidal pendulum as an alternative method to test the isochronism regardless of amplitude and discuss the practical utility of it in class.

Contemporary architectural structures have diverse and complex forms. Such structural variety demands requisite performance from the connections in the steel structure so that the latter could resist a horizontal force, such as an earthquake. The connections are the all-important components that create the discontinuous form and that support stress concentration, determining the stiffness and toughness of the entire steel frame. In this study, a real-scale column-to-beam connection was constructed in the 600MPa-grade high-strength and high-performance steel, to test its behavior. Its material and welding characteristics were examined in this study, and its structural performance was analyzed by conducting seismic-resistance tests on the full-scale, cross-shaped column-to-beam welded connections with non-scallop, ordinary-scallop, and reinforced-scallop details. The weld ability of the high-strength, high-performance steel was also evaluated, and data regarding the seismic design for practical application were provided.

In today's world where a preference for prestigious brands prevails, it's essential to have creative design conceptions rather than try simple mimicking or following in order to be recognized for creative and objective design works. In that sense, the development of clothes design using construction lines offers a great approach towards the ideas of reinterpreting and creating new designs since it creates new forms by understanding lines as signs of conception and transforming them. That approach allows a designer to improve his or her imagination, creativity and expression in a freer and richer manner, think of many original ideas through diverse changing processes, and develop the skill to visualize the ideas by incorporating geometric forms of abstract lines into clothes. When approaching the conception of clothes design from the standpoint of construction lines, you need to adopt more specific and systematic design methods instead of vague imagination to introduce simple facts or theories to a new design process. That's one of the ways you can approach clothes design easily and enhance your conception skills. The process of clothes design according to the conception of construction lines is composed of the following stages; the preparation stage involves an understanding of the principles and the entire process of clothes design conception based on construction lines; the idea stage requires a designer to make free alterations of the given basic construction lines by moving and replacing the lines and sides in diverse ways; in the creation and expression stage, the designer uses the newly reconstructed construction lines to create clothes design; and in the evaluation stage, the designer makes a presentation of his or her subjective design works and has his or her works assessed and tested in an objective fashion. In today's modern society that demands new and original globalized design, the results of the study will help to invigorate the development of new fashion design in a more systematic and practical manner by suggesting a feasible and gradual educational program for the development of design based on the technique of construction lines.

The importance of the green space in urban area has been increasing. There are the increasing needs of creation and sustainable management of urban forest. In order to satisfy the need, it is necessary to set indicators for sustainable urban forest. With this regard, this study is to derive the indicators for evaluation of the urban forest through literature reviews, experts opinion, and field survey. The results of the study, the indicators consist of the ecological healthiness, socio-cultural function, and scenic beauty. The ecological healthiness includes stability and naturality (e.g. area, native species, connectivity etc.). The socio-cultural function contain improvement of living environment, stable emotion, community, and environmental education. The scenic beauty includes environmental-friendly facilities, maintenance of urban forest. The indicators have high feasibility to create and manage the urban forest through evaluating urban forest in practical. This indicators are useful to guide to develop urban forest and park.

This study aims to explore how the transformational leadership (consisting of three factors"charisma, individualized consideration, and intellectual stimulation) and the organizational culture (typified by developmental, rational, consensual, and hierarchical culture) are related to the organizational effectiveness (consisting of job satisfaction, organizational commitment, and intention to leave a job) of dental clinics. We found the following empirical results through a survey of 378 persons who work in dental clinics. Firstly, the respondents acknowledged charismatic leadership as the typical type of leadership ; as for organizational culture, a culture of consensus is recognized as the representative type. Secondly, transformational leadership has different effects according to the type of organizational culture: a positive influence in developmental and rational cultures, but a negative influence in consensual and hierarchical cultures. Thirdly, developmental culture has proven to be the most suitable for increasing job satisfaction and organizational commitment. The developmental, rational, and consensual cultures have all contributed to reducing intention to leave among clinic staff, whereas in the hierarchical culture, intention has been elevated. Fourthly, transformational leadership has a positive effect on the job satisfaction and organizational commitment; the intent to leave has been lessened under individualized consideration and charismatic leadership, but has been increased under leadership of intellectual stimulation. Fifthly, it is consideration and charisma that help to increase organizational effectiveness. These influences will become more effective through a developmental culture. Based on the above empirical results, we propose practical measures to improve the organizational effectiveness of clinics, in particular dental clinics. In order to build developmental culture, the doctor (manager) should produce an atmosphere in the clinic in which staff members are able to create and jointly own ideas and then promote awareness of staff participation. Additionally, in order to bring leadership of charisma and consideration into full play, the doctor should shape a relationship of mutual trust mainly by recognizing and praising the work of clinic staff. Finally, the doctor needs to acknowledge that organizational effectiveness can be significantly improved by increasing the transparency of the business.
