In high resolution imaging devices, smaller aperture in the color filter causes cross talk which provides incorrect information. Plasmonic color filters (PCFs) have been reported as an alternative of the conventional color resist based-color filter (CRCF) and many studies on PCFs demonstrated the filtering function by PCFs with a sub-micron size. In this work, we investigated the cross talk performance of PCFs compared to CRCFs. The effect of cross talk over distance from the filter were measured for each filter. Despite poorer spectral filtering characteristics, PCFs were more robust against cross talk than CRCFs. Also, the further away from the filter, the more cross talk appeared. As a result, PCFs showed less cross talk than CRCFs at about 82% of the results measured at a distance of 2~10 ㎛. This study will help to make practical use of PCFs in high-resolution imaging applications.

Present-day organizations have become largely dependent on mobile instant messaging services (MIMs) for various organizational purposes. Focusing on the increasing use of MIMs in today's organizations, this study aims to explain how different aspects of KakaoTalk, the most dominant MIM in Korea, influence employees' attitudes toward their current employers, and how these attitudes impact the employees' intentions to stay at their present workplaces. Overall, with the exception of one factor (satisfaction with KakaoTalk use), all other factors (perceived quality of information exchanged through KakaoTalk, belongingness through KakaoTalk, and KakaoTalk overload) significantly influenced employee's attractiveness toward their current employers. Specifically, while KakaoTalk overload's effect on perceived organizational attractiveness was negative, two other factors were positively associated with it. Perceived organizational attractiveness also strongly influenced employees' intention to stay at their present workplaces. These findings contribute to expanding practical and theoretical understandings regarding the critical roles of MIMs in the efficient management of organizations in this hyperconnected society.

The competitive circumstance among domestic TV stations caused by TV channels of comprehensive programming appearance in 2011 brought the rapid growth of talk shows. The purpose of this article is to diagnose the talk shows trend from a self-disclosure perspective to consider a social aspect and communication structure in popular TV programs. 26 domestic TV talk shows from 2011 to 2014 were collected and analyzed to understand current state and grasp genres and formats. The results show that self-disclosure talk shows are increasing under the leading of terrestrial TV channels. The talk only type of talk show is superior in numbers compare to the variety type talk show includes such as game and quiz. The popular talk shows were produced inside studio mainly with fun seeking topics. Multi MCs and guests encountered many to many communication structure. The marked changes among self-disclosure talk shows to encourage participation of entertainers' family members and ordinary people are emerging and it is a noteworthy phenomenon.

IM(Instant Messenger) chatting service can carry user's various information including life style, geographical position, and psychology & crime history and thus forensic analysis on the IM service is desirable. But, forensic analysis for KakaoTalk's chatting service is not well studied yet. For this reason, we study KakaoTalk's forensic analysis focusing on chatting service. This paper first details a general method of IM forensics investigating the previous articles about IM forensics although there are not many articles. Second, we discuss methodologies for IM forensics wherein we present analysis of table structure and method for reconstruction of chatting message. These result in the basic element of forensic tools of KakaoTalk chatting message. Last, we compare artifacts of KakaoTalk with that of WhatsApp. We conclude that these applications are, at least, different in that table structures and the ways to reconstruct chatting messages are not same and therefore digital evidences or artifacts are not same and somewhat distinct.

The purpose of this study is to investigate low- and middle-income preschoolers' use of contextualized and decontextualized talk. The contextualized and decontextualized talk of 70 five-year-old children were analyzed by children's gender and their socioeconomic status. The participants, as dyads, participated in a peer play session for 10 minutes. The play sessions were videotaped and the videotaped data were transcribed. Each transcript was analyzed according to the modified version of Curenton et al. (2008)'s coding schemes. The results showed that children from middle-income families engaged more in both contextualized and decontextualized talk than children from low-income families. Also, girls from middle-income families engaged in more contextualized-decontextualized talk(psychological states) than girls from low-income families.

In this paper, the modeling capabilities of an object-oriented simulator, AgvTalk is demonstrated by designing and simulating a conceptually configuration of AGV systems, known as the tandem configuration. The characteristics and design methodology in AgvTalk are described between the tandem configuration for AGV systems and conventional AGV systems. Also, simulation between the conventional AGV system and its corresponding tandem AGV system are compared with AgvTalk in the job shop environment. From the simulation results, the characteristics of each system observed are discussed.

If the right and left signals of a binaural sound recording are reproduced through loudspeakers instead of a headphone, they are inevitably mixed during their transmission to the ears of the listener. This degrades the desired realism in the sound reproduction system, which is commonly called 'cross-talk.' A 'cross-talk canceler' that filters binaural signals before they are sent to the sound sources is needed to prevent cross-talk. A cross-talk canceler equalizes the resulting sound around the listener's ears as if the original binaural signal sound is reproduced next to the ears of listener. A cross-talk canceler is also a solution to the problem-how binaural sound is distributed to more than 2 channels that drive sound sources. This paper presents an effective way of building a cross-talk canceler in which geometric information, including locations of the listener and multiple loudspeakers, is divided into angular information and distance information. The presented method makes a database in an off-line way using an adaptive filtering technique and Head Related Transfer Functions. Though the database is mainly concerned about the situation where loudspeakers are located on a standard radius from the listener, it can be used for general radius cases after a distance compensation process, which requires a small amount of computation. Issues related to inverting a system to build a cross-talk canceler are discussed and numerical results explaining the preferred configuration of a sound reproduction system for stereo loudspeakers are presented.

Recently, IM(Instant Messenger) of KakaoTalk is being used on smart devices such as smartphones. Because IM service can carry user and/or suspector's various information including life style, geographical position, psychology and crime history, forensic analysis on IM service is desirable. But, forensic analysis for KakaoTalk is not well studied yet. This paper studies a proper forensic method for KakaoTalks, finds artifacts location, reconstruct the list of contacts and the chronology of the messages that have been exchanged by users. Proposed methodology and analyzed information can provide a basic platform for forensic tool.
