One of the main reasons of information divide of multi-cultural family is caused by language barrier that is associated with low education level. In addition the social problem can be triggered by the information divide that may increase the gap of economic inequality. With respect to the overall capability of accessibility of digital devices and the level of data utilization, the parent of muiti-cultural family's level is inferior to that of the parents of an ordinary family. However the traditional learning contents management system for those parents is not appropriate to decease the gap of the information divide. To handle this problem, it is necessary to construct a customized learning contents management system that is used to support the education of the parents of multi-cultural family depending on the level of understanding the learning contents written in korean. In this paper we design the korean to korean translation based learning contents management system and show the result of its prototype.

Coordinate constructions in natural language pose a number of difficulties to natural language processing units, due to the increased complexity of syntactic analysis, the syntactic ambiguity of the involved lexical items, and the apparent deletion of predicates in various places. In this paper, we address the syntactic characteristics of the coordinate constructions in Korean from the viewpoint of constructing a competence grammar, and present a version of combinatory categorial grammar for the analysis of coordinate constructions in Korean. We also show how to utilize a unified lexicon in the proposed grammar formalism in deriving the sentential semantics and associated information structures as well, in order to capture the discourse functions of coordinate constructions in Korean. The presented analysis conforms to the common wisdom that coordinate constructions are utilized in language not simply to reduce multiple sentences to a single sentence, but also to convey the information of contrast. Finally, we provide an analysis of sample corpora for the frequency of coordinate constructions in Korean and discuss some problematic cases.

Most of wearable platforms(i. e. Samsung Gear, Android Wear) are using most of Tizen mobile platform features without any changes. However wearable devices have unique characteristics due to wearable type, small battery, screen shape, poor network and relative short but frequent user interfaces. In general, a wearable device has a process to be paired with the mobile device, which includes capability exchange that includes information such as device model name, network capability (3G, LTE, Wi-Fi and so on), manufacturer and supported languages. In other word, a wearable device depends heavily on the companion device (i. e. phone, tablet), so wearable platform should consider this. In this paper, we provide the effective application management mechanism using these characteristics of wearable platform to enhance user experience and to reduce sluggish of wearable platform.

물은 생물의 생존을 위해 필수적인 요소로 인류가 시작된 이래로 물을 효율적으로 이용하고 안전하게 관리하기 위한 노력은 계속되어 왔다. 최근 지구 온난화가 주요 원인으로 알려진 국지성 집중호우의 피해는 매우 심각하며, 이로 인해 치수에 대한 중요성은 날로 커지고 있다. 지금까지 사용해 왔던 홍수 예 경보 과정은 특정 지점의 유출량을 예측하기 위해서 강우-유출 모형을 운영하였다. 그러나 물리적 모형의 경우 운영에 필요한 매개변수의 결정과정이 복잡하고, 매개변수 결정을 위해 많은 자료를 필요로 한다. 또한 그 매개변수의 결정과정은 많은 불확실성을 포함하고 있어서 모형의 운영을 위한 전처리과정과 계산과정을 거치는 동안 발생한 오차가 누적되어 결과물 속에는 많은 오차가 포함되어 있다. 본 연구에서는 기존의 홍수 예 경보 시스템의 문제점과 불확실성을 최대한 감소시키고 더 우수한 유출량 예측을 위해 neuro-fuzzy 추론 기법을 이용한 모형인 ANFIS(Adaptive Neuro-Fuzzy Inference System)를 사용하여 하천수위를 예측하였다. ANFIS는 신경회로망과 퍼지이론을 결합한 기법으로 신경회로망의 구조와 학습 능력을 이용하여 제어환경에서 획득한 입 출력 정보로부터 언어변수의 membership 함수와 제어규칙을 제어 대상에 적합하도록 자동으로 조종하는 기법이다. 본 연구에서는 ANFIS를 사용하여 탄천 하류에 위치한 대곡교의 수위를 예측하였다. 분석을 위해 2007년부터 2011년까지의 탄천 유역의 관측 강우자료와 수위 자료 중 강우강도와 지속시간, 강우 형태에 따라 7개의 강우사상을 선정하였다. 학습자료 및 보정자료의 변화에 따른 예측 오차를 비교하여 모형의 적용성과 적정성을 평가하였다. 적용결과 입력자료 구성의 경우 해당 시간의 강우량 및 수위자료와 10분 전 강우자료를 이용한 모델이 가장 우수한 예측을 보였고, 학습자료의 경우 자료의 길이가 길고, 최대홍수량이 큰 경우 가장 우수한 예측 결과를 보였다. 본 연구의 적용결과 가장 우수한 모형의 경우 30분 예측 첨두수위 오차는 0.32%, RMSE는 0.05m 이고 예측시간이 길어짐에 따라 오차가 비선형적으로 증가하는 경향을 보였다.

Incident management is significant far the traffic management systems. The management of incidents determines the smoothness of freeway operations. The dynamic nature of incidents and the uncertainty associated with them require solutions based on the incident operator's judgment. Fuzz systems attempt to adapt such human expertise and are designed to replicate the decision making capability of on operator. Fuzzy systems process complex traffic information, and transmit it in a simplified, understandable form to human traffic operators. In this study, fuzzy rules were developed based on data from real incidents on Santa Monica Freeway in LosAngeles. The fuzzy rules ail linguistic based, and hence, user-friendly. A comparison of the results from the linguistic model with the real incident durations indicate that the outputs from the model reliably correspond to real incident durations conditions. The model reliably predicts the freeway incident duration. The modes can thus be used as an effective management tool for freeway incident response systems. The approach could be applied to other problems regarding dispatch systems in transportation.

Many researchers have investigated and studied on the knowledge and skills required for IT workforce, such as programmers, systems analysts, and IT managers. The results of these studies helped us not only to understand the changes of IT trends and to prepare IT workers for their future careers. But, the web developer, which is a newly evolving job title, has little been studied. This research is intended to look into the knowledge and skills for web developers by collecting and analyzing the job advertisements posted the commercial job boards in the Internet. The specific technical requirements for Web developers are programming languages knowledge/skills such as Java and JSP, database, and Internet/Web. Knowledge/skills for general development and knowledge on information technology are required in System section. The results of this research is expected to help us understand the knowledge and skills related to web development.

COVID-19 has changed a lot in our daily lives, where school classes and remote classes have been combined or converted to remote classes. Many students spent more time online, and cyberbullying, such as indiscriminate disclosure of their personal information, bullying of their classmates online, increased. In this paper, we propose an online education program as a countermeasure against cyberbullying. This program is designed for elementary, middle, and high school students and can also be used for informatics or ethics classes in the 2015 curriculum. The proposed program is divided into four major themes: 'Cyberbullying,' 'Information Security,' 'Cyber Crime,' and 'Language Violence,' and is divided into a total of ten topics according to its connection. It was organized to teach the topics evenly by grade. Also, the program's feasibility was verified by experts on the selection of educational contents and organizing of contents. In the future, it will be necessary to apply for this program and conduct an effectiveness analysis to measure whether it has effectively contributed to the decrease in cyberbullying rates among students and the improvement of coping skills.

In this study, we examined how the self-efficacies of North Korean defectors affect their adaptation to South Korean social culture. To this end, 209 North Korean defectors living in Seoul, Incheon, Wonju, or Ansan were surveyed. The results obtained showed shorter residence in South Korea and age were associated with greater fear of South Korean society and awareness of language and cultural differences. On the other hand, age and duration of residence were not found to affect relations between social adaptation and perceptions of low social status, discrimination, or prejudice by defectors, which suggests defectors often live in South Korea for a considerable time without overcoming perceptions of discrimination or prejudice. The factor that most influenced adaptation to social culture was self-efficacy, which affected not only socio-cultural adaptation but also self-sufficiency and the ability to promote oneself, which is essential for economic adaptation in South Korean society.

Background and Objectives The objective of this study was to examine the effect of early cochlear implantation (CI) performed in infants less than 12 months of age. Subjects and Method Twenty-five children who received their first CI before 12 months of age were included in this study (infant group). The speech perception and language outcomes of these children were compared with those of 14 children who received their first CI between 13 and 24 months of age (older group). All children received sequential bilateral CI with the inter-stage interval of less than 2 years. Speech perception was measured using Categories of Auditory Performance, monosyllabic word test and sentence test, and language ability was measured using Sequenced Language Scale for Infants, Preschool Receptive-Expressive Language Scale, or Receptive & Expressive Vocavulary Test, depending on the age at the time of testing. Results There were no significant differences in speech perception abilities between the infant group and the older group. The mean expressive language score of infant group was higher than that of the older group, but the difference was not statistically significant. However, the receptive language score of infant group was significantly higher than that of the older group. Conclusion Children who received CI before 12 months of age achieved better receptive language ability than those who received it after 12 months of age. Thus CI should be performed as early as before 12 months of age to achieve better language ability.
