Smartphones are growing more susceptible as technology develops because they contain sensitive data that offers a severe security risk if it falls into the wrong hands. The Android OS includes permissions as a crucial component for safeguarding user privacy and confidentiality. On the other hand, mobile malware continues to struggle with permission misuse. Although permission-based detection is frequently utilized, the significant false alarm rates brought on by the permission-based issue are thought to make it inadequate. The present detection method has a high incidence of false alarms, which reduces its ability to identify permission-based attacks. By using permission features with intent, this research attempted to improve permission-based detection. However, it creates an excessive number of features and increases the likelihood of false alarms. In order to generate the optimal number of features created and boost the quality of features chosen, this research developed an intersection feature approach. Performance was assessed using metrics including accuracy, TPR, TNR, and FPR. The most important characteristics were chosen using the Correlation Feature Selection, and the malicious program was categorized using SVM and naive Bayes. The Intersection Feature Technique, according to the findings, reduces characteristics from 486 to 17, has a 97 percent accuracy rate, and produces 0.1 percent false alarms.

Understanding agent's intent is an essential component of the human-computer interaction of ubiquitous computing. Because correct inference of subject's intention in ubiquitous computing system helps particularly to understand situations that involve collaboration among multiple agents or detection of situations that can pose a particular activity. This paper, inspired by people have a mechanism for interpreting one another's actions and for inferring the intentions and goals that underlie action, proposes an approach that allows a computing system to quickly recognize the intent of agents based on experience data acquired through prior capabilities of activities recognition. To proceed intention recognition, proposed method uses formulations of Hidden Markov Models (HMM) to model a system's prior experience and agents' action change, then makes for system infer intents in advance before the agent's actions are finalized while taking the perspective of the agent whose intent should be recognized. Quantitative validation of experimental results, while presenting an accurate rate, an early detection rate and a correct duration rate with detecting the intent of several people performing various activities, shows that proposed research contributes to implement effective intent recognition system.

This paper proposes a novel way of personalized web search through re-ranking the search results with user profiles of concept-network structure. Basically, personalized search systems need to be based on user profiles that contain users' search patterns, and they actively use the user profiles in order to expand initial queries or to re-rank the search results. The proposed method is a sort of a re-ranking personalized search method integrated with query expansion facility. The method identifies some documents which occur commonly among a set of different search results from the expanded queries, and re-ranks the search results by the degree of co-occurring. We show that the proposed method outperforms the conventional ones by performing the empirical web search with a number of actual users who have diverse information needs and query intents.

The system of washing and shrouding a dead body is a series of procedures for encoffining in funeral rites, which are taken after death indentification by using CHOKWANG and praying for the resurrection of a dead body by calling a soul departed from the body. The washing and shrouding a dead body (hereinafter reffered to as "YEOMSEUP") is the broad concept which contains the procedures of washing, clothing and shrouding the body. The clothing includes washing, putting rices into the mouth. and then dressing while the shrouding includes first wrapping, second-wrapping and encoffining. The clothes for YEOMSEUP (all clothes and articles for funeral rites are designated) will be put in the coffin along with a dead body according to the YEOMSEUP procedures. Dasan, a SILHAK scholar in the late Yi Dynasty, pointed out some problems of the funeral rites observed in those days. At the same time, he found that the problems had arisen from the misinterpretation of the original descriptions in Chinese characters. and had tried to correct them. The books written by Dasan basically emphasized his ideology reshaping the whole procedures by trimming and removing meaningless formalities which are too much luxurious and wasteful and making them as a part of the original principles of the funeral rites. His Intents are clearly shown in his wrings on practical ettiquttes, such as SANGRYESAJON and SANGUIJEOLYO. In its attempt, this study aims at reformulating the DASAN\\`s SANGRYESAJON in terms of YEOMSEUP methods. A lot of virtues of the Dasan, like WOOSU, SIMUI, DAEDAE, MO, SORYUMHYO and DAERYUMHYO could also be found accordingly. The merits and characteristic in funeral rites are an obedience in filial duty, the pursuit of frugality. and the efficiency of practical functions. It could be said that the resurvey of DASAN′s theory on YEOMSEUP procedures is a meaningful work today when the original meaning of funeral rites fades out. Furthermore, discussions of refined burial service and encouraging cremation designed to improve land use, which are widely spread among people, could weaken the basic philosophy of YEOMSEUP and more likely propagate the atmosphere of despising the dignity of human beings.

The objectives of this study were to investigate the effects of brand familiarity and brand recognition on the acceptance of 10 commercial Korean rice wines (yakju). For the consumer preference testing, 104 rice wine drinkers (males, 56; female, 48) from their 20's to 40's were recruited. Consumers first rated the preferences and purchasing intent of the samples without accompanying information about each sample. During a break, brand familiarities and demographics were surveyed. The consumers then rated the preferences and purchasing intent with information about each sample. An analysis of variance was constructed to evaluate the effect of gender, age, and samples on the liking and purchasing intent of the rice wine products. Significant differences were observed for the likings and purchasing intents among the 10 samples with and without brand information, respectively. A paired t-test was performed to evaluate the effect of brand recognition between with and without brand information. A significant effect of brand recognition was confirmed, particularly for the samples with higher levels of brand familiarity. Internal preference mapping was performed to understand the overall relationships between each consumer's liking of the 10 samples with and without brand information. Acceptance tended to shift toward more familiar products when the information was presented.
