This study is a basic study to develop standards and foundations for the establishment of traditional Korean gardens and aims to understand the current status of their components and expression methods and identify problems by investigating Korean gardens developed overseas. Nine sites were selected for field surveys and monitoring assessments. The results suggest: Overall, there is a lack of popular generality and temporal characteristics among these gardens, as they are mere reproductions of historical elements. There have also been errors of traditional and experimental interpretations. In terms of design aspects, traditional gardens are primarily compilations of landscape elements and certain ornamental features. In terms of landscape, they tend to be insufficient in parlaying appropriate spatial scales and experiential hierarchies; they also lack considerations of the context of neighbouring landscapes. In terms of guidance and information delivery, there is a worldwide lack, in general, of recognition of Korean gardens, given the broad variety of names attached to them; therefore, name standardization is recommended. In terms of development, management, and use, it is essential that designers suggest plant types, as well as alternatives, that match the characteristics of a given space; a receptive attitude vis-$\grave{a}$-vis the characteristics of their use is required.

The importance of smart learning (SL) has been emphasized in schools. Additionally, the significance of smart work (SW) in improving business performance has gained much attention among industries. From theoretical, technological, and environmental perspectives, SL and SW are somewhat similar. Therefore, a case study was performed to find a way to link SL and SW, and a linking model was proposed for this purpose. Because laptops are considered a pivotal element in the technological aspect of SL, graduate students' use of personal laptops in classes (Bring Your Own Laptop, BYOL) was investigated. The results showed that the students reacted positively to the idea of using personal laptops in class and that they expected to learn IT skills more effectively this way. They listed being able to study even after class and the easy accessibility of relevant data as the strengths of BYOL. However, they cited the heaviness of the laptops and occasional loss of focus during classes as the weaknesses of BYOL. Thus, this study showed the possibility of that students who experience SL can perform better in an SW situation. Therefore, if a policy is enacted that allows students to efficiently use laptops, a greater number of educational achievements will be attained on smart campuses and, subsequently, a greater number of smart workers will be produced.

Cultural goods is carrying nature and value above-mentioned a commodity to what a cultural element was commercialized. And it produced for the purpose of manufacture for popular sales and supply, and holding commercial character. Specially, cultural goods of a museum keeps a good memory to a sightseer, and broaden an educational experience, and the source of profit becomes it to a seller a producer. This cultural goods as they all include the artistic historical figurative background that they are displayed directly and got twisted up to collection have background which became a motive. Cultural goods can acquire cultural difference in globalization and have to be based on the soil of cultural heritage, starting around various cultural materials through practical value to a modern life. Internationally, cultural goods using a culture material development have competitiveness of nation as in it. Therefore, Baekje cultural goods need national and positive aid from the government with the customer satisfaction index considering the modern design, an age group, an internal and external commodity as the difficulty of various commodity development and managing museum shop. Furthermore, like overseas museum shop, if we are practically using on-off line, continuous promoting our commodity, and marketing strategy such as a membership system when buy our cultural goods, a special discount event etc., we can contribute to activate local economy as a museum shop when we have responsibility of the function and the part.

Due to high levels of integration and complexity, the Network-on-Chip (NoC) approach has emerged as a new design paradigm to overcome on-chip communication issues and data bandwidth limits in conventional SoC(System-on-Chip) design. In particular, exponentially growing of energy consumption caused by high frequency, synchronization and distributing a single global clock signal throughout the chip have become major design bottlenecks. To deal with these issues, a globally asynchronous, locally synchronous (GALS) design combined with low power techniques is considered. Such a design style fits nicely with the concept of voltage-frequency-islands (VFI) which has been recently introduced for achieving fine-grain system-level power management. In this paper, we propose an efficient design methodology that minimizes energy consumption by VFI partitioning on an NoC architecture as well as assigning supply and threshold voltage levels to each VFI. The proposed algorithm which find VFI and appropriate core (or processing element) supply voltage consists of traffic-aware core graph partitioning, communication contention delay-aware tile mapping, power variation-aware core dynamic voltage scaling (DVS), power efficient VFI merging and voltage update on the VFIs Simulation results show that average 10.3% improvement in energy consumption compared to other existing works.

This study intends to look into the perception gap among Korean and Chinese consumers regarding the product attitudes toward smart phones and repurchase intention as well as the user experience. First, this study showed that there are gaps among Korean and Chinese consumers, regarding smart phones, toward their experiences of usage satisfaction, usefulness, design satisfaction, and evaluation from other people and that Chinese consumers have higher awareness of every experience element concerning UI than Korean consumers. Second, concerning the difference in the product attitudes toward smart phones, it turns out that Chinese consumers also have higher awareness of it than Korean consumers. Third, regarding the difference in repurchase intention for smart phones among Korean and Chinese consumers, this study shows that Chinese consumers are likely to have more intention than Korean consumers. because their average value is higher than Korean consumers' even though the difference are not statistically significant. This study is expected to have academic meaning(significance) for providing basic materials of comparative study between two countries regarding the user experience about smart phone as well as some useful implications for the competitive power improvement of Korean smart phone related companies in China.

Toward the systematic and efficient management of national land, National Geography Institute(NGI, National mapping agency) has been producing national basemap in automated process since middle of 1980's. Under the National Geographic Information System(NGIS) Development Plan, NGI began to produce digital maps in the scales of 1:1,000, 1:5,000, 1:25,000 since 1995. However, those of digital maps that have been generated under NGIS Development Plan need to be modified and corrected due to lack of technology and experience in making digital maps. In this context, those digital maps generated are currently in great need for improving the data dictionary. It is fully appreciated in previous research that data dictionary will be a key element far users and generators of digital maps to rectify the existing problems in digital maps as well as to maximize the application of digital maps. In this paper, we analyzed existing problems in digital maps based on previous researches and interviews with engineers in different fields of geospatial engineering. And then, the existing data dictionary has been redefined and modified. In the line of modification process, a relational matrix was established fur each topographic feature defined in the existing feature classification system. This paper presents newly proposed data dictionary which conforms to newly defined feature classification system from previous research performed by NGI.

Companies strive to have the ability to flexibly respond to environmental changes in modern society with its rapidly changing business environment. That is, companies try to achieve the corporate performance by using a variety of strategies since companies that don't go along with changes in industry are likely to fall behind. Also, the corporate performance is a key element in national competitiveness, and government is willing to support companies to maximize their performance in various ways. This study examines whether there is a difference between corporate strategies and government policies according to the retention and the type of certification of innovation. The company's strategy configuration effort is largely divided into exploration and exploitation of external knowledge, while the government's policy is divided into direct support, indirect support, and financial support. The corporate performance is analyzed using technological performance; innovative perspective and the sales; and the actual corporate performance as proxy variables. As a result, the variable affecting the performance differs according to the retention of certification of innovation. The variable affecting the corporate performance differs according to the type of certification of innovation as well. Therefore, it was found that companies can achieve the corporate performance by considering the situation at hand and the differentiated action strategies depending on the type of certification of innovation.

The condition, characteristics, and stability of slopes, as well as the consequences of slope failure, need to be understood for the proper stabilization of slopes and preclusion of potential disasters arising from slope failure. Here, a slope code system (SCS) that succinctly and accurately reflects the various conditions of a slope is proposed. The SCS represents the condition, characteristics, and geotechnical stability of slopes, as well as the consequences of slope failure, and the method is quickly and easily applied to a given slope. The SCS comprises five elements: 1) the slope material; 2) the genetic origin (rock type) and geological structure of the slope; 3) the geotechnical stability of the slope; 4) the probability of failure and remedial works made upon the slope; and 5) the consequences of failure. A letter code is selected from each element, and the result of the evaluation and classification of the slope is given as a five-letter code. Because the condition, characteristics, and geotechnical stability of a slope, as well as the consequences of slope failure, are provided by the SCS, this system will provide an effective mechanism for the maintenance and management of slopes, and will also allow more informed decision-making for determining which slopes should be prioritized for remedial measures.
