The purpose of this study is to improve interaction with the construction subject by analyzing the contents and contents of users' involvement in landscaping works. For this purpose, this study selected the Gwanggyo Residential Land Development District Public Landscape Project in Suwon, Gyeonggi Province. For four years before and after the completion, the opinions of tenants were used as research data. Both qualitative and quantitative analyses of 412 complaints received by the project implementation office and local government were conducted. As a result, first, the main purpose of suggesting opinions was 'demanding and expressing complaints', and there were many 'parks' and 'rivers'. In terms of content, "quality" was the most pointed out, but many kinds of trees, such as tree planting, ecological river construction, and pavement construction were also mentioned. Second, the extraction of key words from content analysis was the most common method. Followed by 'additional foodstuff' and 'moving to the toilet and management building'. Much of the point of view about dead wood has continued to be conspicuous in the process of waiting to be dealt with at the time of transplanting. Third, the validity of the contents of the complaints was evaluated as a five - point scale. Therefore, the opinions raised were unreasonable, but overall, there were more complaints with certain objectivity.

The purpose of this study is to gain knowledge about the influence of running time of 3D stereoscopic video on audience perceptions. This study compares the influence of running time between 20 minutes and 40 minutes of 3D stereoscopic music shows on audience perceptions such as perceived characteristics, impression, presence, entertainment, fatigue and unnatural looking images. After experiment with 40 samples, the present research found that when people watched shorter 3D stereoscopic music video, they perceived more 3D functionality, such as depth, image conveyance and message conveyance. The results also suggest that people who watched shorter 3D stereoscopic video felt more impression such as definiteness and freshness from the 3D images. Moreover, the result confirm that when watching shorter 3D images, people felt more a sense of presence. Findings of this study have important practical implications how running time is important to 3DTV viewers. Since the nature of this study is exploratory, more research about segmented running time and genre, etc. of 3D stereoscopic videos will be needed.

Recently, various risks of smartphone hacking are emerging. Smishing crime techniques become more cunning and its damage has been increasing, thereby requiring effective ways of preventing and coping with smishing. Especially, it is emphasized the need for smartphone users' security awareness and training besides technological approach. This study investigates the effective method for providing news messages in order to improve the perception of risk from smishing. This research empirically examines that the degree of optimistic bias on risk perception can vary depending on news frame, topic type, and involvement regarding smishing. Based on the findings, it identifies the factors influencing risk perception and verifies effective ways of promoting individual security awareness on smishing. The results of this study provide implications that assist in educating, campaigning and promoting information security awareness for smart device users.

This study is to examine relationship between immersiveness aspect and the recognition of garners who are exposed to PPL (Product Placement Advertisement) in online game. The frequency of exposure, the placement type of PPL, the perception under the threshold of consciousness and the interest at the product and knowledge about PPL have been widely known as the factors of effectiveness in PPL advertising. In this study, 'immersiveness' is newly introduced to investigate the effectiveness of PPL advertising due to the unique characteristics of game which easily leads to immersion. Control group is exposed to movie clip and experimental group to lacing online game. In conclusion, the deep immersion has reduced the perception level of user on PPL except the variable of PPL placement. This study suggests that how to design the PPL placement in game for enhancing marketing effect is all the more vital, in spite of the result that the player in high immersion cannot distinguish different images.

3D images and videos are required viewers to wear 3D glasses. According to the data, about half of Korean people wear glasses or contact lens and this implies 3D video viewers may have a trouble due to putting a pair of 3D glasses atop their glasses. The purpose of this study is to examine gamers' perceived characteristics, presence, and fatigue according to video gaming display (2D vs. 3D) and glasses whether wearing or not. The results show that the interaction effect of the display and wearing glasses was statistically significant in the perceived presence, and the main effect of the display was statistically significant in the perceived characteristics and fatigue.

Locative media is fundamentally different from traditional media in terms of being packed with user's space, place, and position nearby, which does not simply mean user's physical coordinates. This study has been started that I was drawn by the tendency of which current locative media contents are based on 'location-based information,' and closely related with 'Augmented Reality.' I wonder how media user's psychological experience/involvement are revealed when the media environment changes by the progress of technology. I wonder how media users perceive 'social presence' formed by locative media in current locative media environment. Particularly, the fact that user's perception of social presence formed in locative media conflicts with the previous computer-mediated communication(CMC)'s attributes deepened my curiosity. In this study, the idea of 'more-proper-construct' is suggested, the characteristics of social presence in current locative media is considered, and is investigated by qualitative methodology how the 'location-based' attributes and 'AR' contribute to forming the social presence.

As violent video game is used based on active interaction and involvement of users, it is widely thought that it may have more effect on individual violence and aggressive action than existing violent videos. This study aimed to examine the effect of user experiences in the violent video game such as hostility, anger, arousal, enjoyment and identification on users' aggressive action. For this purpose, the first person FPS shooting game that consists of violent contents was employed to carry out playtest for 80 subjects with 40 male and 40 female university students. As a result, it was found that the user's arousal level, state anger, enjoyment and identification experience by the use of violent video game had an effect on aggressive action. Among factors that have aggressive action in the used of violent video game, besides emotion and arousal, the level of identification with a game character was found to be important effect factor. Hostility factor that was assumed to have effect on aggressive action was not significant, but enjoyment of game was proved to have effect on aggressive action of users.

Recent advances in the 4th Industrial Revolution have accelerated the change of the shopping behavior from offline to online. Search queries show customers' information needs most intensively in online shopping. However, there are not many search query research in the field of search, and most of the prior research in the field of search query research has been studied on a limited topic and data-based basis based on researchers' qualitative judgment. To this end, this study defines the type of search query with data-based quantitative methodology by applying machine learning to search research query field to define the 15 topics of search query by conducting topic modeling based on search query and clicked document information. Furthermore, we present a new classification system of new search query types representing searching behavior characteristics by extracting key variables through principal component analysis and analyzing. The results of this study are expected to contribute to the establishment of effective search services and the development of search systems.
