For the cooperative video surveillance of dashboard cameras in nearby vehicles, a fast and energy-efficient asynchronous neighbor discovery protocol is indispensable because a dashboard camera is an energy-hungry device after the vehicle's engine has turned off. In the existing asynchronous neighbor discovery protocols, all nodes always try to discover all neighbors. However, a dashboard camera needs to discover nearby dashboard cameras when an event is detected. In this paper, we propose a fast and energy-efficient asynchronous neighbor discovery protocol, which enables nodes : 1) to have different roles in neighbor discovery, 2) to discover neighbors within a search range, and 3) to report promptly the exact discovery result. The proposed protocol has two modes: periodic wake-up mode and active discovery mode. A node begins with the periodic wake-up mode to be discovered by other nodes, switches to the active discovery mode on receiving a neighbor discovery request, and returns to the periodic wake-up mode when the active discovery mode finishes. In the periodic wake-up mode, a node wakes up at multiples of number α , where α is determined by the node’s remaining battery power. In the active discovery mode, a node wakes up for consecutive γ slots. Then, the node operating in the active discovery mode can discover all neighbors waking up at multiples of β for β ≤ γ within γ time slots. Since the proposed protocol assigns one half of the duty cycle to each mode, it consumes equal to or less energy than the existing protocols. A performance comparison shows that the proposed protocol outperforms the existing protocols in terms of discovery latency and energy consumption, where the frequency of neighbor discovery requests by car accidents is not constantly high.","PeriodicalId":272384,"journal":{"name":"Journal of the Korea society of IT services","volume":"49 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128223874","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, many research has focused on meaning of the text itself. And there is a lack of study for text's creation subject. Therefore, this research consists of sex/age text classification with by using 20,187 Facebook users’ posts that reveal the sex and age of the writer. This research utilized Convolution Neural Networks, a type of deep learning algorithms which came into the spotlight as a recent image classifier in web text analyzing. The following result assured with 92% of accuracy for possibility as a text classifier. Also, this research was minimizing the Korean morpheme analysis and it was conducted using a Korean web text to Authorship Attribution.

Literature review was concentrated on definition of open data and abroad utilization indicators whereas case study analyzed current situation of four web-sites providing copyrighted public records. Converged opinions from in-depth interview and various statistical data was analyzed as a basis for grounded theory, then a paradigm model was constructed and future improvement plans were presented. The findings imply that opening of copyrighted public records is not just important for quantitative results, rather it requires qualitative improvement providing latest credible information that is consistent with the demand of the customer.

Our research shows that the announcement of the information security certification significantly influences the market value of the corresponding firm. The certified firms rise, on average, o.4993% (-2 day), 0.5462% (+1 day) of their market value.

Besides, characters and their names in a novel are created by the author’s pen and imagination. As a result, any proper noun dictionary cannot include all kind of character names which have been created or will be created by authors. In addition, since Korean does not have capitalization feature, character names in Korean are harder to detect than those in English. Fortunately, however, Korean has postpositions, such as “-ege” and “hante”, used by a sentient being or an animate object (noun). We call such postpositions as animate postpositions in this paper. In a previous study, the authors manually selected character names by referencing both Wikipedia and well-known people dictionaries after utilizing Korean morpheme analyzer, a proper noun dictionary, postpositions (e.g., “-ga”, “-eun”, “-neun”, “-eui”, and “-ege”), and titles (e.g., “buin”), in order to extract social networks from three novels translated into or written in Korean. But, the precision, recall, and F-measure rates of character identification are not presented in the study. In this paper, we evaluate the quantitative contribution of animate postpositions to character identification from novels, in terms of precision, recall, and F-measure. The results show that utilizing animate postpositions is a valuable and powerful tool in character identification without a proper noun dictionary from novels translated into or written in Korean.

SFA supports salespeople’s activities such as selection of potential customers, creative value proposition, after-sales services, etc. SFA is increasingly used in many companies because it has the advantages to raise the salespeople’s productivity by developing forecasting ability, value proposition ability, after sales service ability etc. Many researches have shown that implementation of SFA leads to the increase of salepeople performance, organizational performance, and quality of customer relationship. However, Some prior studies have discussed on the SFA implementation failure and pointed out that one of important causes of this failure is salespeople’s resistance to SFA. Although many researches explain SFA acceptance phenomenon using Technology Acceptance Model (TAM) and Theory of Planned Behavior (TPB), these researches didn’t deeply investigate the salespeople’s resistance to SFA. Therefore, this study focuses on the factors influencing salespeople’s resistance to SFA and the relationships among these factors. This study identified three factors (salespeople’s perceived loss of power, perceived loss of autonomy, and perceived time and effort waste) influencing salespeople’s resistance to SFA. The hypotheses testing results showed that salespeople’s perceived loss of power and perceived time and effort waste significantly increased salespeople’s resistance to SFA. And salespeople’s perceived loss of power plays a mediating role between perceived loss of autonomy/perceived time and effort waste and salespeople’s resistance to SFA. At the end of the paper, theoretical and managerial implications of this study and the limitations and future research directions are discussed.","PeriodicalId":272384,"journal":{"name":"Journal of the Korea society of IT services","volume":"176 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114740045","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Excluding missing data, 120 usable data were analyzed. From the results, first, three SNS motivations (i.e. Information, social and entertainment) has a positive impact on the perceived value of SNS (i.e. perceived usefulness and perceived enjoyment). Second, the perceived usefulness and perceived enjoyment positively affect customer-brand relationship (brand intimacy, brand attachment). Third, the customer-brand relationship is positively related to brand trust. Implications, limitations and future research directions of the study were also discussed.

This is known as “Shadow IT.” In spite of efficiency gains or cost savings, Shadow IT presents problems for companies such as the outflow of enterprise data.
