In the defense software domain where large-scale software products in various application areas need to be built, reusing software is regarded as one of the important practices to build software products efficiently and economically. There have been many efforts to apply various methods to support software reuse in the defense software domain. However, developers in the defense software domain still experience many difficulties and face obstacles in reusing software assets. In this paper, we analyze practical problems of software reuse in the defense software domain, and define core requirements to solve those problems. To meet these requirements, we are currently developing the Component Grid system, a reuse-support system that provides a developer-centric software reuse environment. We have designed an architecture of Component Grid, and defined essential elements of the architecture. We have also developed the core approaches for developing the Component Grid system: a semantic-tagging-based requirement tracing method, a reuse-knowledge representation model, a social-network-based asset search method, a web-based asset management environment, and a wiki-based collaborative and participative knowledge construction and refinement method. We expect that the Component Grid system will contribute to increase the reusability of software assets in the defense software domain by providing the environment that supports transparent and efficient sharing and reuse of software assets.

The purpose of the paper is to analyze the developmental background and practical approaches to the arts of the Dao (道術 dosul) in Daesoon Jinrihoe (大巡真理會) by tracing this concept back to its source and comparing and contrasting Daesoon Jinrihoe's usage of 'arts of the Dao' with the usage found in traditional Daoism. The paper is divided into a preface, conclusion, and two body sections. Especially significant discoveries appear in the second and third sections. In the second section, the Daoist concept of Alterable and Unalterable Degree Numbers (運度定數 yundudingshu, 'degree numbers' suggesting 'fate' or 'destiny') allows for a comparison between the Reordering Works of Heaven and Earth (天地公事 cheonjigongsa) from Daesoon Jinrihoe's The Canonical Scripture (典經 jeon-gyeong) and the Opening of Calamities to Save Humanity (開劫度人 kaijieduren) in Daoism. Here discourse can be provided regarding the cause of calamities (劫 'jie' in Chinese and 'geop' in Sino-Korean). Additionally examined are the deep grievances between divine beings and humans and the cosmic cycles of growth and decay as both of these relate to the reason for calamities. As for the resolving of calamities, there are two differing perspectives proposed by Daesoon Jinrihoe and traditional Daoism. Daesoon Jinrihoe believes that Kang Jeungsan (姜甑山) led changes and renewal through the Reordering Works of Heaven and Earth. In this context, clergy and laity play roles as assistants. However, Daoism emphasizes gaining merit from the recitation of scriptures and the collective participation of immortals rather than relying completely upon divine intervention from the Celestial Worthy of the Primordial State (元始天尊 yuanshi tianzun). In the third section, 'The Origin and Application of the Arts of the Dao (道術 daoshu),' analysis is provided regarding the origin and connotation of five directional generals (五方將 wufangjiang), the twenty-four generals (二十四將 ershijiang), the twenty-eight generals (二十八將 ershibajiang), and the forty-eight generals (四十八將 sishibajiang). Likewise examined is the relationship between the arts of the Dao in The Canonical Scripture and Thunder Rites in the Shen Xiao Lineage (道教神霄雷法 daojiao shenxiao leifa) of Daoism. Lastly, some points are made about the operation of two ceremonies: The Ceremony of Transformation and Pacing (遁甲步罡儀式 dunjiabugangyishi) and Divination through the Formula Disc of the Six Ren Gods (六壬式盤占卜 liuren shipanzhanbu).

A 'flowered-wall,' which are also called a 'flower plant patterned wall,' or a 'flower patterned wall,' is a wall of a building or a fence with various patterns on it. A flowered-wall can be an external mean to look into the owner's authority and values while internally it possesses the symbolic meaning of wishing the well-being and peace of the household. In the research area of the flowered-wall, the walls located in the palace were well researched in various studies across architecture, horticulture, and art design, however, the walls belonging to the local regional traditional folk houses and temples have been involved in little to no research in the landscape architectural area. Taking notice of this perspective this study researched and analyzed the cases of the flowered-walls of the traditional folk houses and the temples that belonged to the national and municipal cultural properties of Jeollabuk-do Province from the landscape architectural perspective. The whole samples were examined and it was shown that there were 9 traditional folk houses with flowered-walls. Among the temples there were 7 cases. Therefore the research focusing on tracing the shape and symbolic meaning of the flowered-walls in the 16 cultural properties located in the Jeollabuk-do Province which consisted of traditional folk houses and temples resulted in the following. Flowered-walls displayed hierarchical differentiation revolving around the main space and its spacial characteristic. This differentiation is variously displayed across the flowered-wall, gable, crack plastering, and chimney. In the case of the folk houses the symbols have the meaning of the prosperity of the household and progeny, exorcism, longevity, number of fortune, harmony, and peace etc that prays for practical wishes such as long life and good health with the prosperity of their descendants. Meanwhile in the temples, symbols indicating an easy passage into eternity, perpetuation of the Buddha-nature, and three marks of existence are applied, differentiating from the folk houses by the appliance of the religious values in the patterns. In conclusion this research resulted in the rightful illumination on the local landscape culture, the possibility of expressing the Korean sentiment through flowered-walls in the contemporary space, the reassessment of flowered-walls, and the provision of basic data for a plan to success the cultural heritage.

Although service innovation is not a new concept, innovation research in general tends to focus on technological innovation by manufacturing firms. With this view, innovation studies focus on product(e.g., goods) and process(e.g., product systems) innovation, ignoring service innovation and its inherent opportunities. Since major economy has been transformed to service economy, service innovation is considered a new effective way to sustain and gain a competitive advantage. Service innovation is no longer regarded merely as a side activity to product innovation; it has become a main research topic in its own right, accompanied by an increasing focus on services. While the number of service innovation studies has increased dramatically in the past 30 years in international research, few studies have been performed in domestic studies because domestic service innovation research began from the middle of 2000. In addition, there are no comprehensive literature reviews describing the evolution of service innovation research in both international and domestic studies because of the heterogeneities of service industry and multidiscipline characteristics of service innovation studies. To bridge this research gap, the purpose of this paper is to perform an extensive literature review and synthesis to enable a critical review of extant research on service innovation and trace its evolution, which will establish a foundation for further studies. By reviewing 169 articles (136 international papers; 33 domestic papers) published between 2000 and 2014 (in past 15 years), primarily in leading service, innovation and management information systems journals, this study analyzes the progression of service innovation research according to the four aspects such as number of studies, topics, methodologies and target industries. Overall, the view of service innovation has evolved, from a complement of traditional product innovation to a multidimensional, all-encompassing concept that entails several functions, both within and outside the firms. The results showed that domestic research still stays at the formation phase of service innovation studies although international research is in the maturity or multidimensional phase. We found increasing recent activities pertaining to service innovation, resulting from the increasing interest in services innovation across various industries and the links of new topics to the service innovation concept in both international and domestic studies. However, the main focus of service innovation research showed a different propensity between international and domestic studies: the former mainly focuses on a much more diversified pattern, emphasizing the linkages between service innovation and business strategy while the latter mainly focuses on the service innovation process(system) and service design. In addition, there are many case studies in domestic studies while many empirical studies in international studies. Domestic studies should increases the understanding of the interplay between service innovation and product innovation within manufacturing firms. Furthermore, rather than focusing on intrinsic distinctions between service innovation and product innovation, researchers should strive to develop and conceptualize service innovation in domestics studies. The present research also provides useful implications for practitioners. First, this study contributes to expand the current understanding of service innovation research by performing an extensive literature review. Second, tracing and comparing the progression and trends of service innovation research between international and domestic studies, this study showed the similarities and differences between them, which provide practical guidance on future research directions and research agenda. Third, this study performed literature review establishing the analysis system in the initial stage and using them to analyze articles, which is leading to explain the research review of service innovation more systematically and objectively. Finally, this study suggests the domestic researchers their future interests and topics of service innovation research.

Recently, as competition in the market evolves from the competition among companies to the competition among their supply chains, companies are struggling to enhance their supply chain management (hereinafter SCM). In particular, as blockchain technology with various technical advantages is combined with SCM, a lot of domestic manufacturing and distribution companies are considering the adoption of blockchain-oriented SCM (BOSCM) services today. Thus, it is an important academic topic to examine the factors affecting the use of blockchain-oriented SCM. However, most prior studies on blockchain and SCMs have designed their research models based on Technology Acceptance Model (TAM) or the Unified Theory of Acceptance and Use of Technology (UTAUT), which are suitable for explaining individual's acceptance of information technology rather than companies'. Under this background, this study presents a novel model of blockchain-oriented SCM acceptance model based on the Technology-Organization-Environment (TOE) framework to consider companies as the unit of analysis. In addition, Value-based Adoption Model (VAM) is applied to the research model in order to consider the benefits and the sacrifices caused by a new information system comprehensively. To validate the proposed research model, a survey of 126 companies were collected. Among them, by applying PLS-SEM (Partial Least Squares Structural Equation Modeling) with data of 122 companies, the research model was verified. As a result, 'business innovation', 'tracking and tracing', 'security enhancement' and 'cost' from technology viewpoint are found to significantly affect 'perceived value', which in turn affects 'intention to use blockchain-oriented SCM'. Also, 'organization readiness' is found to affect 'intention to use' with statistical significance. However, it is found that 'complexity' and 'regulation environment' have little impact on 'perceived value' and 'intention to use', respectively. It is expected that the findings of this study contribute to preparing practical and policy alternatives for facilitating blockchain-oriented SCM adoption in Korean firms.

LOD(Linked Open Data) cloud is a practical implementation of semantic web. We suggested a new method that provides identity links conveniently in LOD cloud. It also allows changes in LOD to be reflected to searching results without any omissions. LOD provides detail descriptions of entities to public in RDF triple form. RDF triple is composed of subject, predicates, and objects and presents detail description for an entity. Links in LOD cloud, named identity links, are realized by asserting entities of different RDF triples to be identical. Currently, the identity link is provided with creating a link triple explicitly in which associates its subject and object with source and target entities. Link triples are appended to LOD. With identity links, a knowledge achieves from an LOD can be expanded with different knowledge from different LODs. The goal of LOD cloud is providing opportunity of knowledge expansion to users. Appending link triples to LOD, however, has serious difficulties in discovering identity links between entities one by one notwithstanding the enormous scale of LOD. Newly added entities cannot be reflected to searching results until identity links heading for them are serialized and published to LOD cloud. Instead of creating enormous identity links, we propose LOD to prepare its own link policy. The link policy specifies a set of target LODs to link and constraints necessary to discover identity links to entities on target LODs. On searching, it becomes possible to access newly added entities and reflect them to searching results without any omissions by referencing the link policies. Link policy specifies a set of predicate pairs for discovering identity between associated entities in source and target LODs. For the link policy specification, we have suggested a set of vocabularies that conform to RDFS and OWL. Identity between entities is evaluated in accordance with a similarity of the source and the target entities' objects which have been associated with the predicates' pair in the link policy. We implemented a system "Change Acceptable In-Depth Searching System(CAIDS)". With CAIDS, user's searching request starts from depth_0 LOD, i.e. surface searching. Referencing the link policies of LODs, CAIDS proceeds in-depth searching, next LODs of next depths. To supplement identity links derived from the link policies, CAIDS uses explicit link triples as well. Following the identity links, CAIDS's in-depth searching progresses. Content of an entity obtained from depth_0 LOD expands with the contents of entities of other LODs which have been discovered to be identical to depth_0 LOD entity. Expanding content of depth_0 LOD entity without user's cognition of such other LODs is the implementation of knowledge expansion. It is the goal of LOD cloud. The more identity links in LOD cloud, the wider content expansions in LOD cloud. We have suggested a new way to create identity links abundantly and supply them to LOD cloud. Experiments on CAIDS performed against DBpedia LODs of Korea, France, Italy, Spain, and Portugal. They present that CAIDS provides appropriate expansion ratio and inclusion ratio as long as degree of similarity between source and target objects is 0.8 ~ 0.9. Expansion ratio, for each depth, depicts the ratio of the entities discovered at the depth to the entities of depth_0 LOD. For each depth, inclusion ratio illustrates the ratio of the entities discovered only with explicit links to the entities discovered only with link policies. In cases of similarity degrees with under 0.8, expansion becomes excessive and thus contents become distorted. Similarity degree of 0.8 ~ 0.9 provides appropriate amount of RDF triples searched as well. Experiments have evaluated confidence degree of contents which have been expanded in accordance with in-depth searching. Confidence degree of content is directly coupled with identity ratio of an entity, which means the degree of identity to the entity of depth_0 LOD. Identity ratio of an entity is obtained by multiplying source LOD's confidence and source entity's identity ratio. By tracing the identity links in advance, LOD's confidence is evaluated in accordance with the amount of identity links incoming to the entities in the LOD. While evaluating the identity ratio, concept of identity agreement, which means that multiple identity links head to a common entity, has been considered. With the identity agreement concept, experimental results present that identity ratio decreases as depth deepens, but rebounds as the depth deepens more. For each entity, as the number of identity links increases, identity ratio rebounds early and reaches at 1 finally. We found out that more than 8 identity links for each entity would lead users to give their confidence to the contents expanded. Link policy based in-depth searching method, we proposed, is expected to contribute to abundant identity links provisions to LOD cloud.
