This study analyzed the impact of negative information on co-branding, targeting co-branding consisting of a symbolic brand and a functional brand with similar brand assets. Through attribution theory, when consumers are exposed to negative information, they will infer the cause of the negative information. As a result, it was confirmed that when co-branding with a symmetrical symbolic brand and a functional brand, negative information has different effects on co-branding depending on the type. Negative information about the quality of co-branded products had a more negative impact on consumer attitudes than negative information about the iconic brand. It was confirmed that negative information about functional brands has a smaller impact than negative information about co-branding, but has a greater impact than negative information about symbolic brands. In addition, it was confirmed that negative information about the symbolic brand had a smaller negative impact on co-branding than negative information about the quality or functionality of the co-branded product.

Iron has a vital role in the human body, including the central nervous system. Increased deposition of iron in the brain has been reported in aging and important neurodegenerative diseases. Owing to the unique magnetic resonance properties of iron, MRI has great potential for in vivo assessment of iron deposition, distribution, and non-invasive quantification. In this paper, we will review the MRI methods for iron assessment and their changes in aging and neurodegenerative diseases, focusing on Alzheimer's disease. In addition, we will summarize the limitations of current approaches and introduce new areas and MRI methods for iron imaging that are expected in the future.

The purpose of this study is to summarise the educational meanings of Official Foreign Language Schools(hereafter, OFLS) in Korea, 1895-1906. Especially, I try to find out the foreign language policy of the Joseon Dynasty and the comparative superiority between six foreign language schools - Japanese School, English School, French School, Russian School, Chinese School, and German School - through the traits of teachers and the change of students numbers at the Regulation Period. As a part of Kabo Reforms, the government had abolished the of Civil Service Examination System and status system, and foreign languages worked as a cultural capital to acquire modern civilization and to escalate one's social status. The results were as follows: Firstly, the OFLS have to be regarded as one of the highest educational institute during the Regulation Period. The eligibility of the OFLS was over 15 years old, but most of the incoming students were over 20 years old. Secondly, many of the OFLS's teachers were specialists of military, diplomat and mechanics. Especially, Martel, the teacher of French school played an important role for the neutral diplomacy policy of the Great Korean(Dae-Han) Empire during the Regulation Period. Thirdly, the recruit of new members of the OFLS was affected by the political and social circumstances at that time. Fourthly, the statistics of incoming students during the Regulation Period was concentrated on Chinese school, French school, and English school in due order. Thus, it differed from the commonly accepted ideas of students' statistics which was concentrated on English School and Japanese School. Fifthly, the OFLS were not only for the training of official interpreters(譯官通事), but also the cultivation of civil servants who could become statesman.

Studies have been carried out on the unusual molecular nonrigidity of CoⅢ(PymS)3 and Cp* RhⅢ(PymS)2(PymS:2-mercaptopyrimidine). The crystal structure of CoⅢ(PymS)3 approximates to an octahedral mer isomer with 4-membered N-Schelating fashion. For Cp*RhⅢ(PymS)2, one PymS ligand bonds to the rhodium ion in an S-monodentate mode (Rh-S(2) = 2.366(1)Å) while the other ligand chelates to the metal ion in an N,S-bidentae mode (Rh-S(1)=2.414(1);Rh-N(1)=2.103(3)Å). Even though the conformations and configurations of both complexes are still retained in solution, an unusual nonrigidity for the protons of the PymS region is obsered in the solution. The broad proton signals of CoⅢ(PymS)3 exhibit a temperature-dependence in the range of -40∼40℃ with a free energy of activation ΔG=64.49kJ/mol(40℃). For Cp*RhⅢ(PymS)₂,such a fluxionality has been markedly observed in solution. This fluxional behavior can be explained in terms of "ligand tautomerism" in metal complexes containing potential tautomeric forms.

As nonexisting information affects actual information release rate, the study noted that the absence of records leads to the "nonexistence of information." Therefore, in this research, it was argued that records management should be thoroughly controlled from the stage of record production to solve problems such as the loss/damage/neglect/destruction/misclassification/ reduction of preservation periods and more. Through the management from the production stage, it is expected that the nonexistence of information problem will not occur and can be used as a tool for a demonstration of why the nonexistence of information exists even if such information occurs.

The purpose of this study is to present an evaluation model to measure the clarification level of stakeholder requirements of public sector software projects in the Republic of Korea. We tried to grasp the quality of proposal request through evaluation model. It also examines the impact of the level of stakeholder requirements on the level of system requirements. To do this, we analyzed existing research models and related standards related to business requirements and stakeholder requirements, and constructed evaluation models for the system operation concept documents in the ISO/IEC/IEEE 29148. The system operation concept document is a document prepared by organizing the requirements of stakeholders in the organization and sharing the intention of the organization. The evaluation model proposed in this study focuses on evaluating whether the contents related to the system operation concept are faithfully written in the request for proposal. The evaluation items consisted of three items: 'organization status', 'desired changes', and 'operational constraints'. The sample extracted 217 RFPs in the national procurement system. As a result of the analysis, the evaluation model proved to be valid and the internal consistency was maintained. The level of system operation concept was very low, and it was also found to affect the quality of system requirements. It is more important to clearly write stakeholders' requirements than the functional requirements. we propose a news classification methods for sentiment analysis that is effective for bankruptcy prediction model.

Stream service environment demands real-time query processing for voluminous data which are ceaselessly delivered from tremendous sources. Typical R-tree based query processing technologies cannot efficiently handle such situations, which require repetitive and inefficient exploration from the tree root on every data event. However, many stream data including sensor readings show high locality, which we exploit to reduce the search space of queries to explore. In this paper, we propose a query processing scheme exploiting the locality of stream data. From the simulation, we conclude that the proposed scheme performs much better than the traditional ones in terms of scalability and exploration efficiency.
