Early, mid, and late maturing soybean varieties were artificially infested with larvae of Delia platura at seeding, and then later development and productivity of soybeans were studied. In addition, in hope to utilize as possible tactics in the management of D. platura in soybeans, cultural factors such as contents of organic matter in soil, soil types, and the use of plastic mulching on the degree of damage to soybean plants by D. platura were examined. Primary leaf damage by the larva delayed the forthcoming vegetative growth but not the blooming which is initiated by the change in day length. Degree of delay in growth was more severe where leaf damage was induced by insect infestation than where artificially excised, apparently owing to simultaneous damage in stems and roots besides primary leaves. Productivity of soybeans also dropped significantly in plants with 25 % or more loss in the primary leaf area by the larva. Both transparent and black plastic mulchings shortened the period from seeding to emergence of soybean thus reducing the chance of possible attack by the larva. Soybean seedlings grown in clay loam or clay were attacked less by the larva than those in other types of soil. High organic matter content in the soil enhanced speed of emergence resulting in less larval damage to the seedling.

In this study, a tree growth model is designed to represent a variety of trees consisting of a outdoor terrain of game efficiently and naturally. The proposed tree growth model is an integrated tree growth model, and is configured using the following approaches: (1) the tree modeling method based on growth volume and the convolution sums of divisor functions, which is used to model a variety kind of trees more intuitively and naturally; (2) a rendering method using a level of detail of branch based on instancing for real-time processing of numerous trees with complicated structures; and (3) a combination of the above methods to efficiently implement a game landscape. The natural and diverse growths of trees that emerged using the proposed tree growth model is evaluated through experimentation, along with the possibility of implementing the natural game landscape and the efficiency of real-time processing.

This research aims to examine compositional and microstructural properties of grayish-blue-powdered celadon in Wonju Beopcheon-temple site. X-ray fluorescence sequential spectroscopy (XRF) with micro-point analysis, scanning electron microscopy (SEM) with energy dispersive spectroscopy (EDS) and X-ray diffraction (XRD) were applied to determine the chemical composition, microstructure and crystallinity of samples, respectively. As a result, the average compositions of bodies were low silica ($RO_2$) and high flux (RO+$R_2O$). Owing to the high content of calcium oxide the glaze is considered lime type between limealkali type. The body of celdon sheard was found quarts, mullite, microcline, albite. Especially, the body's chemical compositions were compared to the results of previous studies by using a Seger formula. The compositional properties of Grayish-blue-powdered celadon in Wonju Beopcheon-temple site showed diffrently from the the other grayish-blue-powdered celadon.

This study is based on the 'National Pilot Project on Digital Signage in Sejong Special City', one of the pilot projects initiated by the Ministry of Public Administration and Security. This project was an attempt to present the digital signage as a 'public service content platform' integrated with smart technologies. This study suggests that the planning strategy for placing public service contents on digital signage platform should focus on interests of local communities or users rather than high-tech suppliers of digital signage. In consideration of growing needs for smart technology-based public service, this study concentrates on the strategy for developing 'public digital signage services'. In addition, 'digital signage service tools' were designed to easily establish or execute the strategy. The aim of this study is developing the strategy to make digital signage a public cultural service platform as well as a digital advertisement tool. The final goal of this study is to demonstrate public value creation performance of the 'Revitalisation Project of Sejong City's Commercial Districts', which was possible thanks to the proactive involvement of citizens coupled with progressive utilization of interactive media.

This paper intends to analyze the role expansion of characters, which was an important factor in setting the worldview in storytelling. With the development of media, the way of setting the worldview began to change. At the center of these changes are 'Transmedia' and 'Metaverse', which have recently been receiving attention. With the development of trans media, where the intersection and convergence of media is actively attempted, characters are breaking free from their innate limitations, crossing various media, and performing various activities in new stories. In addition, in the metaverse, an extended concept of the real world, avatars play a role in constructing and expanding the metaverse world as users and creators. By analyzing these changes, we would like to deal with the phenomenon in which character setting, which was used as an element in orthodox world view setting, replaces the world view.

In Korea, there are a total of 8 creative cities selected by UNESCO in 7 fields. UNESCO creative city refers to a network of creative cities with international level of experience, knowledge, and expertise in the field of culture and arts. Based on the PCSI 2.0 model, this study conducted a satisfaction survey of experts on Daegu's Creative City. Variables were composed of service quality, social responsibility, inconsistency, satisfaction and performance, and service quality was measured by dividing it into three categories: content quality, delivery quality, and environmental quality. Therefore, this study verified that the three types of quality, social responsibility, and inconsistency affect satisfaction, and that satisfaction affects performance. As a result of the study, it was found that the three service quality did not directly affect satisfaction, but rather affected satisfaction through inconsistency. So, 3 out of 10 hypotheses were rejected.

This paper analyzes the actual 'content' and 'role' of the intrinsic motivation of creative laborers during the creative production process. Based on semi-structured intensive interviews with 16 light-entertainment television PDs in South Korea, this paper articulated that intrinsic motivation towards creative work could be understood as a desire to maintain their level of enjoyment from creative work. The desire was classified into two different types of 'enjoyment', one was the enjoyment based on the expectation regarding the creative job, and the 'enjoyment' experienced primarily related to the creative production process that allows creative workers to actualize individual creative ambitions. In addition, such intrinsic motivation tended to provide a strong driving force for creative workers as they endured unfavorable working conditions that resulted from market principles(viewership ratings), economic stability, and work-life balance. This paper proposes that the tendency of creative workers to endure various undesirable working conditions is based on a strong intrinsic motivation to maintain their level of enjoyment from their creative career.

The purpose of this study is to compare the academic achievements of these two eras with the content and performance of the bronze ware decorative patterns in the Song dynasty and age of the Minguo. We investigated the origins and developmental process of the bronze ware decorative pattern research in Chinese bronze research history and examined their academic value. Studying bronze ware is a scholarly study. In the past, research focused on classifying letters on bronze ware. However, research on bronze ware decorative patterns was neglected. Bronze ware decorative patterns are associated with archeology and mythology studies and provide important clues as to the imagination of ancient people. The study of bronze ware in China began with the Song dynasty. Since then, research on bronze ware has been revived in the Qing dynasty, although there has been no academic achievement regarding bronze ware decorative patterns. However, at the age of the Minguo, the achievements of bronze ware decorative patterns continued to follow the Song dynasty.

The Web environment of the frontend domain is increasingly competitive to preempt the new standard of presentation layer. N-Screen, a service that enables users to seamlessly use one content in various devices in Korea, is competing for market preemption by recognizing it as a core service of the future. In the cloud computing, N-screen is a typical service type. However, most of the frontend research required for groupware in enterprise environments has been limited to responsive web design for the web and native apps for mobile. Gradually, the need for MVC design patterns is increasingly widening in enterprise environments to overcome the cultural differences of companies and to support one source multi-use strategy supporting multiple devices and development productivity. Therefore, in this study, we will analyze and design JPetStore with hybrid application design based on Spring MVC, e-government standard framework environment of next generation web standard, and provide reference model of frontend hybrid apps design in future enterprise environment.
