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.

I made an analysis on the case of Kakao Talk, which is Korean top mobile instant messaging service, to find the growth potential of Korean Social Network Service in the global market. First, I found that unlike the PC messenger services, Kakao Talk is not only unlimited in mobile IM service provider but also has evolving into a social network service firm. Second, attempts with a variety of social services such as photo-based Kakao Story and Marketing Platform for Mobile Game, Kakao Talk successfully landed as a SNS company. Third, with 'Plus Friends' Service, soon-to-be launched Avatar and App Market Service, Kakao Talk is evolving into social media and social platforms. The big success of Kakao Talk in Korean market is expanding and reproducing into Japanese and Southeast Asian markets through the 'Line' serviced by NHN. Line is applying the proven success stories of Kakao Talk to the Japanese and Southeast Asian markets. It means that Kakao and Line, both are mobile IM services, have raised the possibility of success in the global SNS market although online web-based SNS Cyworld has failed in the global market.

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 suggest areas for improvement of KakaoTalk. KakaoTalk is used by everyone in Korea, and even elementary school students have been using it a lot recently. Therefore, to help parents feel safe about their children using KakaoTalk, and to ensure that children are not worried about their parents when using them, I would like to examine each user's experience to pinpoint the problem. As a method of study, a survey and interview was conducted on eight parents and eight children using KakaoTalk. Through this, the parents could not trust KakaoTalk in terms of reliability when they saw their children using KakaoTalk. Based on this research, we hope to improve KakaoTalk through further research so that parents and children can use Kakao Talk safely.

KakaoTalk, a Korean mobile instant messenger service launched by KAKAO Inc., has grown remarkably popular in a short period of time, with its number of subscribers exceeding 100 million as of July 2013. Today, KakaoTalk is an everyday communication tool among most Korean mobile users. Although KAKAO has been the subject of many business and consumer studies, the KakaoTalk platform strategy has not been studied thoroughly. In this study, we analyze its platform strategy through the lens of several widely utilized frameworks such as Platform Leadership (Gawer & Cusumano 2002, 2008), Winner-take-all dynamics (Eisenmann et al. 2006), and Open Service Innovation (Chesbrough 2011). Our results show that Eisenmann et al (2006)'s "Winner-Take-All" platform best explains how KakaoTalk dominated its rivals, Mypeople by Daum Communications and Line by Naver Corporation. In surpassing its rivals, KAKAO delivered a solution to the 'essential problem' that mobile social communication should be upgraded from mobile companies' paid "Short Message Service" (SMS). By doing so, KakaoTalk fulfilled the first requirement of Gawer & Cusumano (2008)'s "Coring" strategy, which explains how a new platform is created. KakaoTalk also satisfied the second requirement of "Coring" by providing economic incentives for KakaoTalk members to interact through its Games and Items store. Actively accepting its customers' ideas and upgrading its services, KAKAO reinforced its platform leadership to its customers and put Chesbrough (2011)'s "Outside In - Open Service" innovation strategy into practice.

본 논문에서는 한국어 대화 엔진에서의 문장 분류 방법에 대해서 소개한다. 문장 분류시 말뭉치에서 관찰되지 않은 표현들을 포함한 입력 발화를 처리하기 위하여, 태깅되지 않은 뉴스 데이터로부터 일반적인 단어 의미 벡터들이 훈련 및 성능 평가되었고, 이를 문장 분류기에 적용하였다. 또한, 실 서비스에 적용 가능한 빠른 분류 속도를 유지함과 동시에 문제에 특화된 의미 벡터들을 학습하기 위하여, 기존에 사용되던 캐릭터 기반 의미 벡터 대신 도메인 특화 단어 의미 벡터의 사용이 제안되었다. 실험 결과, 자체 구축된 테스트 말뭉치에 대하여 본 논문에서 제안된 시스템은 문장 단위 정확률 96.88, 문장당 평균 실행 시간 12.68 msec을 기록하였다.

The purpose of this study is to analyze the adoption of Kakao Bank in terms of benefits (functional, social, experiential, economic benefits) and differentiated services (customization and service diversity) considering service types. Benefits are personal value consumers attach to the product or service attributes and, therefore, more important than attributes of service itself when using Kakao Bank in the internet based environment. Data was collected using an online and offline survey of 131 Kakao Bank users and analyzed the data using structural equation model (SEM). The results of empirical analysis using SmartPLS show that functional benefit, experiential benefit, and customization are significantly related to the user's satisfaction, but economic benefits, social benefit, and service variety are not. Customer's satisfaction are also showed significantly to be related to the all types of Kakao Bank usage(balance check, transfer, and other services). This study has the significance in that it examines the user's satisfaction and usage of Kakao Bank in terms of benefits and differentiated services while other studies analyzed banking services focusing on the attributes of banking channel itself.
