The purpose of this study is to look at the use of heuristics when a sixth grader solves a problem. Two research questions have been formulated: The similarities and differences in the use of heuristics when a student solves two problems that are science-knowledge-based and not science-knowledge-based, and the different types of prompts. A male sixth grade student participated in this study. All of the information for the study was collected in three interviews. The interviews began with observing the student's solving problems. The student was asked how and why he solved problem that way. There were some interactions between the researcher and the student during the interview procedures. As results of this study, eight general heuristics were used in both solutions: Check examples for support of an idea: check examples for exceptions to an idea: restate the problem: compare to known examples or patterns: make a hypothesis; check the relevance of other information present; use analogy: and recognize patterns/similarity. There seemed to be more similarities than differences in the type of general heuristic that were used in the two problem solutions. The student was systematic and consistent in his use of the general use of heuristics. Five types of interviewer prompts were detected in the two problem solutions, directional cues, modeling, clarity, problem posing, metacognition and validation.

Providing services using kiosks is actively carried out between suppliers and consumers. These service processes have recently begun to play a dominant role in transactions. However, previous self-service technology (SST) studies or kiosks have not fully reflected the changing environment surrounding these different technologies. To cover the updated business environments, we combined qualitative and quantitative research methods. Through qualitative research and a review of previous studies, the variables emphasized as motivations and constraints for kiosks use and those that can be newly illuminated were selected for this study. We then applied the variables to the research model to assess their influence. In terms of the motivations for using kiosks, the results suggest that perceived usefulness and compatibility as service quality, forced use, and perceived service providers' efficiency as provider polices, absorptive capacity, and habit as an individual characteristic and social influence as a subjective norm have a significant effect on the attitude toward kiosks. In terms of constraints, difficult to use and need for interaction predicts the attitude toward kiosks. Attitude toward kiosks, perceived behavioral control, and social influence are directly related to the intention to use kiosks. Lastly, intention to use kiosks plays a significant role as an antecedent of revisit intention. Using these empirical results, we propose both academic and practical implications for future kiosks use.

Medicinal plants and their products are popular in Estonia. There are two approaches to use of herbal products: first, that based on traditions and practical experience and, second, that supported by scientific evidence. It is important to marry these two approaches. One place where traditions and new knowledge could meet is the pharmacy. In this study we evaluated knowledge about the use and safety of herbal products of pharmacy customers in South-Estonia. A convenience sample of pharmacy customers in south Estonia (n = 196) participated in the study. Of the survey participants, 76% were frequent or occasional users of herbal products and considered these products safe (75%) and effective (73%). Herbal products were mostly (91%) consumed for prophylaxis or treatment of minor illnesses. Main information sources about herbal products were pharmacists (75%) and package information leaflets (65%). Mode of action (95%), administration (81%) and indication (77%) were the information details more frequently sought from the pharmacy about herbal products. Of the survey participants, 22% described some problems connected with the use of herbal products. Herbal products are popular in Estonia and pharmacists have an important role in counselling on these products. Despite knowledgeable use of herbal products and infrequent experience of side effects with these products, safety issues should be more stressed in the providing of information details to pharmacy customers.

The rapid use of Facebook among colleges, the present study was to explore the motivations of college owned Facebook among college students. The factor analysis The factor analysis showed that the college students perceived that the intimacy, update of college information, sharing daily lives, use of time, seeking useful information are important motivations when they use college Facebook. The extracted factors such as emotional intimacy, information update and sharing daily lives also play significant variables to affect Facebook effectiveness such as "like" and "sharing others." The results suggest that Facebook managers need to use college Facebook as a social medium not by one way communication medium to the college students.

The purpose of this study is to investigate determinants of intent to use a wireless information technology(WIT) of University Hospital Nurses. The independent variables used in the study are usefulness, compatibility, social environment, perceived readiness, technical readiness, organizational readiness and socio-demographic characteristics. The dependent variable is the intent to use a wireless information technology(WIT). The sample used in this study consisted of 297 nurses selected from a university hospital located in Wonju, Gangwon-do, Korea Data were collected with self-administered questionnaires and analyzed using multiple regression analysis. The results of the study revealed that 5 independent variables of usefulness, compatibility, perceived readiness, technical readiness, and organizational readiness were found to have significant effects on the nurses' intent to use a WIT. As a conclusion, it is important to make organizational, clinical, and technical environment WIT-friendly prior to applying WIT to hospital nurses. In addition, it is also important to provide an education and training for nurses to improve their skill of using WIT and to make the new WIT compatible with the existing nursing information system.

Recently, social security problems have been caused by the development of the software industry, and a variety of automation techniques have been used to verify software stability. In this paper, we propose a method of automatically detecting a use-after-free vulnerability on Windows system calls using dynamic symbolic execution, one of the software testing methods. First, a static analysis based pattern search is performed to select a target point. Based on the detected pattern points, we apply an induced path search technique that blocks branching to areas outside of interest. Through this, we overcome limitations of existing dynamic symbolic performance technology and verify whether vulnerability exists at actual target point. As a result of applying the proposed method to the Windows system call, it is confirmed that the use-after-free vulnerability, which had previously to be manually analyzed, can be detected by the proposed automation technique.
