  • 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.

  • The purposes of this study were to examine the influence of the self-identity, parenting style, peer attachment, and relationship with teacher on career identity, and to verify if self- identity shows the moderating effect in the relationship among the parenting style, peer attachment, relationship with teacher, and career identity of middle school students. The data of 3rd-year middle school students, from the 1st grade panel of 'Korea Children And Youth Panel Survey(KCYPS)' by National Youth Policy Institute, was used as the analysis data. The program which was used for the analysis was SPSS ver 22.0 for descriptive, Cronbach's α, and multiple regression analysis. The results of this study are as follows. First, it was revealed that the most influential variable for career identity was self identity, followed by peer attachment, while relationship with teacher is least influential. Parenting style did not have a direct effect on career identity. Second, it was revealed that self-identity had a moderating effect when the interaction between parenting style and the self-identity, and the interaction between relationship with teacher and the self-identity were injected. Therefore, if the education related to the self-identity is conducted continuously in the home economics subject, the conflict and anxiety on the career problem of middle school students will be reduced and the career identity will be developed more effectively.

  • Even though the variety of expressions are dealt with in Korean elementary mathematics, the systematization of the subject matter of expressions is still insufficient. This is basically due to the failure of revealing clearly the identity of expressions dealt with in elementary mathematics. In this paper, as a groundwork to improve this situation, after the classification of signs as elements constituting expressions, in a position to consider elementary mathematics using transitional signs such as ${\square}$, ${\triangle}$, etc and words or phrases in expressions, expressions were defined and classified based on that classification of signs. It can be presented as the conclusion that the following four judgements which helps to promote the systematization of the subject matter of expressions are possible through this definition and classifications. First, by clarifying the identity of the expressions, any mathematical clauses or sentences can be determined whether those are expressions or not. Second, Forms of expressions can be identified. Third, the subject matter of expressions can be identified systematically. Fourth, the hierarchy of the subject matter of expressions can be identified.

  • This study tries to investigate the influence of parents' neglect on adolescents' school adjustment, and to prove the mediating effects of self-identity and life satisfaction on the relationship between two variables. Data from 5th year(2014) Korean Children and Youth Panel Study(KCYPS) on 2035 nation-wide second year middle school students was analyzed by utilizing Regression analysis and path analysis. Results of the analysis showed first, parents' neglect had a negative effect on adolescents' self-identity, life satisfaction, and school adjustment. Second, adolescents' school adjustment improved with their self-identity and life satisfaction included as mediating effects. Third, the effect of parents' neglect on adolescents' school adjustment was partly mediated by the effects of subject's self-identity and life satisfaction. Furthermore, the need for program development to enhance adolescents' self-identity, life satisfaction and school adjustment was suggested.

  • The purpose of this study was to identify the mediating effects of spiritual experience and depression between self-identity and subjective well-being. The subjects of this study were 138 pastor's wives, and mediating effects were analysed through path analysis and Sobel test. As a result of analysis, first, there were significant relationships among self-identity, spiritual experience, depression, and subjective well-being, but not between spiritual experience and depression. Second, spiritual experience and depression had significant mediating effect within the relationship of self-identity and subject well-being. Third, self-identity had not significant direct effect on subjective well-being. Forth, spiritual experience had not significant direct effect on depression. Implications of these results were explored in relation to the importance of self-identity and spiritual experience that could be taken to improve subjective well-being. In addition, suggestions for future research were discussed.

  • Gender role identity is a key subject toward adaptation in later life. In this paper, we tried to understand the specific types and characteristics of gender role identity in view of older men. The research collected and examined 40 representative descriptions representing gender role identity, including 20 for masculinity and 20 for femininity from 40 older men. We obtained four types of gender role identity of older men from this research. "Powerful-expressive type" is energetic and reveals his brave and dominant tendency when they are working. "Powerful-taciturn type" is strongly independent and has a firm conviction, but they do not express those characters and remain silent. "Powerful-paternal type" handles his work with a driving force, and has a tender character. "Paternal-caring type" finds his own worth in life by caring for his family and children, and considers others more than himself. Future research is needed to verify how the types of gender role identity are linked to psychosocial adaptive aspects, health behaviors, mental and physical health.

  • This study focused on difference of the nation's concept between Ko un's Baekdusan and Lee uk's Gohyangsaramdul, Pungungi. These works are epics restructure nation's history. A epic's story provides framework of recognition to social members. An individual and community accept their story and then stories construct pesonal identity and community's identity. So we can say a epic configurates national identity by story nation history and nation territory. The nation's concept is understood steadfast and very pure as like a blood relationship in Korea. This is aspects of Korean nationalism. But the Nation is modern, social and historical concept. That is different from ethnic identity. This way throws open the door to analyze nation identity. Ko un's Baekdusan narrates permanence and sacralization of the nation for emphasizing the unification of North Korea and South Korea. Baekdusan expresses the social desire of Korea in the 1980s. In comparison, Lee uk's Gohyangsaramdul representate ambivalent attitude. One is a position as a settler and the other is a new master of Yanbian Korean Autonomous Prefecture. So Gohyangsaramdul narrates and remembers their motherland Chosun. But Pungungi exclude recognition of Chosun as motherland. This work's narration focuses on association with struggle of classes and anti-Japanese Movement during the Japanese colonial period. Because these events are able to unity Korean and Chines. Three works deal with same history and same background, but those show defferent recognition about the Nation. Because each society has different social desire and expect different future. The present desire and future prospect construct nation identity.

  • This study discusses various conflict situations and unexpressed pathological potential in historical regions. In this regard, the issue of alienation of local people due to local identity was raised and the cause was investigated. It explains the structural origins of local alienation that occurred in the process of objectifying a region and forming its identity. The process of alienation of local residents of local identity identified in this paper was divided and explained in three stages: objectification of the region, symbolization of local identity, and religious materialism of local identity. In addition, in the process, the incorporation of the production mode of intellectual work, the separation of producers, and the loss of the subject-centered control ability over these products were pointed out as problematic situations. The study suggests to change the perception of the region and to restore the control of the local people through narrative in relation to this problematic situation. Thus, this thesis asserts that we need to have doubts about the justification for the public good and the basis of the resulting consensus, and that we should be constantly interested in the pathological signs of society around us.

  • Airport security staff are outsourced workers, whose status is a special security agent under the security service law in Republic of Korea, who are subject to persuing both profitability and public concern at the same time. This paper has chosen the sample of security staff working at Incheon airport. This is because airport security staff is being outsourced, this paper had made an empirical research such areas as the perception of job identity, public service motivation and organizational commitment through job satisfaction. According to statistical research, it was found the perception on job identity by airport security staff had a significant negative effect on both job satisfaction and organizational commitment. The more they have perceived their status as non-permanent status, the less they had job satisfaction and commitment at the same time as a special security agent at airport. Their perception of job identity had a significant effect on such public service motivation factors as 'absorbing public concern' and 'a solicitude'. Lastly, their motivation factors had also significant positive effect on job satisfaction and organizational commitment.
