Abusive behaviors have become a common issue in many online social media platforms. Profanity is common form of abusive behavior in online. Social media platforms operate the filtering system using popular profanity words lists, but this method has drawbacks that it can be bypassed using an altered form and it can detect normal sentences as profanity. Especially in Korean language, the syllable is composed of graphemes and words are composed of multiple syllables, it can be decomposed into graphemes without impairing the transmission of meaning, and the form of a profane word can be seen as a different meaning in a sentence. This work focuses on the problem of filtering system mis-detecting normal phrases with profane phrases. For that, we proposed the deep learning-based framework including grapheme and syllable separation-based word embedding and appropriate CNN structure. The proposed model was evaluated on the chatting contents from the one of the famous online games in South Korea and generated 90.4% accuracy.

Recently, as e-learning technology advances, interaction and data exchange between lecturers and learners have become very important. In addition, accuracy of data delivery and efficiency of system implementation should be ensured. Considering these aspects, SignalR is the most suitable communication method for constructing an audience response system in e-learning. Existing audience response systems require separate wireless devices and have problems with system compatibility. SignalR, on the other hand, is capable of operating in all environments including PC programs, web, Android, and iOS, and has an advantage of being easy to develop applications. As such, SignalR is widely used in chatting functions for small scale, real-time communication system, and it has never been used to implement an audience response system. Thus, for the first time in this paper, an audience response system using SignalR was proposed and an experiment was conducted on whether it was applicable at the e-learning education field. Therefore, from the results fo an experiment, a variety of e-learning environments can be built through the audience response system using SignalR proposed in this paper.

This article focuses on Funology and a new classified application system based on concept of language and thought which are formed by body experience. It is defined by Funology Body as that. Funology Body is classifying and searching system which are consisted of a body, world (environment), and device tool. The body is sectioned by Brain, Eyes, Ears, Nose, Mouth, Hand, Torso, Feet, and Heart according as parts of the human body. This allows intuiting and experience searching as making classified system connected to the application relationship with concept of an each part of body. The Brain of the body is sub-classified by Book, Account, Business, Memory, Education, Search, and Aphorism to imply the application with thought. The Eyes take Video, Photography, and Broadcast for visibility. The Ears is categorized as Music, Instrument, Audio, and Radio for hearing. The Nose gets Perfume, Smell for olfactory sense. The Mouth is sectioned by Food, SNS, Chatting, Email, and Blog for eating and communication. The Hand sorts into Games, Kits, and Editing to handle, create, and play. The Torso is grouped by Health, Medical, Dance, Sport, Fashion, and Testyuorself related by protecting internal and meaning of the body core. The Feet is classified by Travel, Transportation, Map, and Outdoor for moving and concept of expanding the terrain. The Heart is consisted of Fear, Anger, Joy, Sadness, Acceptance, Disgust, Expectation, and Surprise for a human feeling. Beyond that, the World takes News, Time, Weather, Map, Fortune, and Shop, and Device tool gets Interface, Utilities. The Funology Body has a unique characteristic of giving intuitive and sensuous pleasure and reflection of users' attitude and taste for changing application flexibly.

As Internet is spreaded widely, the virtual communities among people with the same interest and hobby are dynamically created. The exchange of fruitful opinion and information makes them to be closed, not only with the help of the messaging system but also wireless terminals. The messaging system is a core technology supporting the global community services like chatting, messenger, short message services, and file sharing services. The paper focus on the design of software architecture for messaging system and the engineering model for QoS support.

Balinese calendar is defined as a unique calendar system for combining solar-based and lunar-based system and assuming local system. It is considered as guidance of Balinese societies' activities management, starting from meeting arrangement, wedding ceremony, to religious ceremonies. Practically, it has developed in the form of printed Balinese calendar and electronic Balinese calendar, either web or mobile application. The core of the function is to find out the day with its various characteristics in the Balinese Calendar. In general, society usually asks the religious leader to find out the day in detail. The technology of NLP combined with models of pattern discoveries supports the arrangement of the interaction model in searching the good day in Balinese Calendar to equip the conventional searching system in the previous applications. This study will design a dialog model with AIML method in multi-parameter basis; therefore, the users will be dynamically able to use the searching content in various ways by chatting in similar with consulting to a religious leader. This model will be applied in a chatbot basis service in telegram machine. The addition of the context recognition section into 4 paterns has been successfully improve the ability of AIML to recognize input patterns with many criteria. Based on the testing with 50 random input patterns obtained a success rate of 92.5%.

최근 WWW상에서 VRML 기반의 3차원 가상공간 구현이 활발하게 진행되고 있다. 대부분의 시스템이 VRML기능의 한계로 인해 다수사용자의 참여와 사용자 상호작용 구현 기이 부족하다. 본 연구에서는 이러한 기능을 포함하는3차원 채팅시스템을 VRML과 Java를 이용하여 개발하였다. 다수 사용자 참여 기능은 Java를 이용하여 클라이언트/서버 시스템으로 구성하였으며 사용자 상호작용 기능은 3차원 가상공간을 걸어 다니는 효과 (walkthrough)를 제어하기 위한 인터페이스로서 EAI(External Authoring Interface)를 이용하여 구현하였다. 본 시스템에서 각 3차원 가상공간에서의 채팅 지원을 위해 여러개 서버를 둘 수 있도록 구성하여 사용자가 서버를 통해 채팅을 위한 가상공간을 추가 혹은 변경할 수 있도록 하였다.

본 논문에서는 다양한 목적의 공동 작업 시스템에서 공통적으로 사용할 수 있으며, 플랫폼에 독립접인 웹 기반의 화이트 보드와 채팅을 설계하고 구현한 내용을 소개한다. 본 논문에서 구현한 시스템은 서버/클라이언트 구조로서, 서버와 클라이언트 모두 JAVA로 구현하였다. 그러므로 플랫폼에 독립적인 서버 시스템(application)을 구성할 수 있으며, 별도의 어플리케이션 없이도 웹 브라우저만 있으면 클라인언트의 접속이 가능하다. 멀티유저와 멀티작업그룹을 지원하기 위해서 서버에는 접속 관리자와 세션 관리자를 두었으며, 각각 쓰레드로 동작하여 서버의 부하를 줄이고, 또한 서버와 클라이언트간의 통신이 실시간으로 이루어지게 하였다. 웹 사이트와 MS Office 문서의 공유, 1:1대화, 작업 포인터 등의 기능을 지원하여 공동 작업의 효율을 증진시키고, 마치 동일한 공간에서 작업하고 있는 듯한 효과를 얻게 하였다.

The reciprocal relationship between the interpersonal tie and the internet dependency is focused in the study. Mainly, chi-squire test and ANOVA are used in testing the hypothesized relationship of the internet dependency with the interpersonal tie before and after using internet. The strong relationship with the internet dependency is found in internet's both-directional communicating function such as chatting, game, gambling, etc. The level of internet dependency is high when individual's tie with friends, colleagues, or neighbors is strong; but it is lower when individual's emotional tie with family members is stronger. It is confirmed that excessive usage of internet damages family relationship. Conversely, it is also clear that the emotional support from family members is essential for preventing or enhancing internet dependency. This implies that internet dependency is not an individual problem, but that it should be treated under the consideration of his/her family system.
