In a world where opportunities and chances are common, the phenomenon referred to as "generation maybe" describes people in their 20s and early 30s who are usually being indecisive. With the increase in breadth of information and choices, the number of people who are hesitant in deciding whether to purchase increases at a fast pace, as does the number of products and services targeting this group. In order to enhance our understanding of the phenomenon of consumer hesitation, this study explores contextual factors and consumer characteristics that affect consumer hesitation in the purchase decision-making process. Specifically, this study examines whether seven contextual factors, self-determination tendencies, and five decision-making styles influence consumer hesitation in the product decision making process. An online survey was administered to test our research questions. A total of 309 Korean consumers (female=48.9%) aged from 20 to 35 were surveyed. A regression analysis revealed that four contextual factors (product involvement, need for information on alternatives, relative price, and uncertain need), two sub-dimensions of self-determination (perceived competence and relatedness), and two decision-making styles (price seeking and advice seeking) have noticeable influences on consumer hesitation. We also found that the degree of consumer hesitation positively influences consumer post-purchase satisfaction. The study concludes with discussions and practical implications.

Objectives: The purpose of this study was to provide basic data on the current status and ways to improve the dental hygiene society by investigating working conditions, working experience, dental institution types among some dental hygienists, and ways to improve the dental hygiene society. Methods: This study conducted an online survey to 450 graduates of the department of dental hygiene in colleges in Gyeonggi, Jeolla and Gangwon Provinces. This study got some help in securing the list of graduates from the heads of the departments. SPSS WIN 23.0 was used to analyze the data. Results: To questions on what is the most important thing in considering to apply for jobs, the highest proportion (39.1%) of respondents designated employee welfare, followed by improvement of clinical dental hygiene (34.0%), of welfare related contents (26.0%), and salary (19.5%). In the relationship between employee welfare and dental institution type and between employee welfare and work experience, employee welfare tend to rise with the increase of work years. In the relationship between the director and staff members, it was found that as work years accumulate, the relationship tends to decrease. The dental clinic with no more than five staff members showed the best relationship between the leader and co-workers, while employee welfare was the highest in the other types of clinics, and the differences were statistically significant. Conclusions: Dental hygienists need to make various efforts to improve their statuses as professionals. In order to secure a part of professionalism, it is necessary for them to make more efforts to realize the health-care professionals being promoted by the Dental Hygienists Association of Korea.

The popularity of augmented reality (AR) applications and games are in high demand. Currently, the best common platform to implement AR services is on a smartphone, as online games, navigators, personal assistants, travel guides are among the most popular applications of smartphones. However, the power consumption of an AR application is extremely high, and therefore, highly adaptable and dynamic low power control schemes must be used. Dynamic voltage and frequency scaling (DVFS) schemes are widely used in smartphones to minimize the energy consumption by controlling the device's operational frequency and voltage. DVFS schemes can sometimes lead to longer response times, which can result in a significant problem for AR applications. In this paper, an AR response time monitor is used to observe the time interval between the AR image input and device's reaction time, in order to enable improved operational frequency and AR application process priority control. Based on the proposed response time monitor and the characteristics of the Linux kernel's completely fair scheduler (CFS) (which is the default scheduler of Android based smartphones), a response time step control (RSC) scheme is proposed which adaptively adjusts the CPU frequency and interactive application's priority. The experimental results show that RSC can reduce the energy consumption up to 10.41% compared to the ondemand governor while reliably satisfying the response time performance limit of interactive applications on a smartphone.

The importance of clear and effective communication at sea has been greatly emphasized due to the increase in multiculturalism on board both ocean-going and coastal vessels, and the necessity of systematic English training based on 'Knowledge, Understanding, and Proficiency' specified in STCW has also been recognized. With these growing needs in mind, the International Maritime Organization (IMO) updated the Maritime English (ME) Model Course 3.17 in 2015 by providing guidelines on language education within two separate categories, General Maritime English (GME) and Specialized Maritime English (SME). The IMO is now attempting to create a new, global framework of ME education and training, and this this new course model must first be thoroughly understood in order to explore the ways to apply the modified version into the context of current ME education in Korea and to design an updated language curriculum. Therefore, the general structural features of the new model course will be explained in this paper, and the course focus set by IMO and to be considered and/or adopted by the Republic of Korea will be closely examined. Finally, suggestions will be made on how to implement this revised model course in practice with the following focus: the development of localized curriculum for GME and SME; the provision of practical teaching guidance through relevant online and offline materials for class and self-study; and the establishment of qualification guidelines and a teaching support system for language teachers in maritime and language education.

The aim of this study is to investigate current status of archiving activities related to producing, collecting and managing information resources of multicultural agencies and organizations in Dae Gu. To do this, 12 agencies and organizations including Multicultural Team of Dae Gu, multicultural family support centers, foreign worker support center, NGOs for immigrants and public libraries were visited. As a result, these agencies and organizations have struggled for producing information resources through online and off-line, collecting information resources from external bodies and managing information resources like official documents, counseling reports, multicultural books and artifacts. But there were problems in archiving information resources. In order to solve problems, first, multicultural agencies and organizations should reinforce responsibilities to produce, collect and manage information resources. Second, public libraries should actively try to collect and organize information resources from these agencies and organizations. Finally, cooperative archiving activities between multicultural agencies and organizations and public libraries are needed.

Objectives: Risk assessment is a tool for predicting and reducing uncertainty related to the effects of future activities. Probability approaches are the main elements in risk assessment, but confusion about the interpretation and use of assessment factors often undermines the message of the analyses. The aim of this study is to provide a guideline for systematic reduction plans regarding uncertainty in risk assessment. Methods: Articles and reports were collected online using the key words "uncertainty analysis" on risk assessment. Uncertainty analysis was conducted based on reports focusing on procedures for analysis methods by the World Health Organization (WHO) and U.S. Environmental Protection Agency (USEPA). In addition, case studies were performed in order to verify suggested methods qualitatively and quantitatively with exposure data, including measured data on toluene and styrene in residential spaces and multi-use facilities. Results: Based on an analysis of the data on uncertainty, three major factors including scenario, model, and parameters were identified as the main sources of uncertainty, and tiered approaches were determined. In the case study, the risk of toluene and styrene was evaluated and the most influential factors were also determined. Five reduction plans were presented: providing standard guidelines, using reliable exposure factors, possessing quality controls for analysis and scientific expertise, and introducing a peer review system. Conclusion: In this study, we established a method for reducing uncertainty by taking into account the major factors. Also, we showed a method for uncertainty analysis with tiered approaches. However, uncertainties are difficult to define because they are generated by many factors. Therefore, further studies are needed for the development of technical guidelines based on the representative scenario, model, and parameters developed in this study.

This study compares blogs of professional reporters with those of citizen reporters in terms of watchdog and interactivity functions. Watchdog function was analyzed in light of the extent of soft news and the degree of critical relationship with the government. Interactivity was assessed by analyzing readers' comments on the articles of reporter blogs. for citizen journalism and for professional one were chosen in order to minimize any discrepancies caused by ideological differences. As a result of the content analyses, citizen reporter blogs were found to deliver soft news more frequently than those of , whereas the former had stronger tendency to maintain the critical relationship with the government than the latter. As for the interactivity function, although the number of comments uploaded to citizen reporter blogs was higher than that of professional reporter blogs, the latter was found to meet the standards of communicative interaction more adequately than the former.

The path-finding algorithm refers to an algorithm for navigating the route order from the current position to the destination in a virtual world in a game. The conventional path-finding algorithm performs graph search based on cost such as A-Star and Dijkstra. A-Star and Dijkstra require movable node and edge data in the world map, so it is difficult to apply online games with lots of map data. In this paper, we provide a Heuristic-based Genetic Algorithm Path-finding(HGAP) using Genetic Algorithm(GA). Genetic Algorithm is a path-finding algorithm applicable to game with variable environment and lots of map data. It seek solutions through mating, crossing, mutation and evolutionary operations without the map data. The proposed algorithm is based on Binary-Coded Genetic Algorithm and searches for a path by performing a heuristic operation that estimates a path to a destination to arrive at a destination more quickly.

Bearing is one of the important mechanical elements used in various industrial equipments. Most of failures occurred during the equipment operation result from bearing defects and breakages. Therefore, monitoring of bearings is essential in preventing equipment breakdowns and reducing unexpected loss. The purpose of this paper is to present an online monitoring method to predict bearing states using vibration signals. Bearing vibrations, which are collected as a form of profile signal, are first analyzed by a discrete wavelet transform. Next, some statistical features are obtained from the resultant wavelet coefficients. In order to select significant ones among them, analysis of variance (ANOVA) is employed in this paper. Statistical features screened in this way are used as input variables to support vector machine (SVM). An hierarchical SVM tree is proposed for dealing with multi-class problems. The result of numerical experiments shows that the proposed SVM tree has a competent performance for classifying bearing fault states.
