As development of personal devices have made everyday use of internet much easier than before, it is getting generalized to find information and share it through the social media. In particular, communities specialized in each field have become so powerful that they can significantly influence our society. Finally, businesses and governments pay attentions to reflecting their opinions in their strategies. The stock market fluctuates with various factors of society. In order to consider social trends, many studies have tried making use of bigdata analysis on stock market researches as well as traditional approaches using buzz amount. In the example at the top, the studies using text data such as newspaper articles are being published. In this paper, we analyzed the post of 'Paxnet', a securities specialists' site, to supplement the limitation of the news. Based on this, we help researchers analyze the sentiment of investors by generating a domain-specific sentiment lexicon for the stock market.

This study aims to examine the suggestions by studies that family predictors are related to developmental outcomes more strongly for children reared principally by their parents compared to those with extensive child care experience. Zero-order correlations between family predictors and developmental outcomes were conducted and the significance of differences in correlation coefficients between the two child care groups were examined. There was no evidence that there exist systematic differences between the two groups in predictive power of family factors except a few exceptions. At 2 years, social parenting style was more strongly associated with communication ability in the extensive child care group. At 3 years, some HOME subscales were related to a child's expressive and receptive vocabulary skills in significantly greater magnitudes in the mother care group. The findings also implied the potential contribution of child care environment on developmental outcomes for those who spend extensive hours in nonmaternal care.

In this paper, we examine the influence of Environmental, Social, and Governance (ESG)-related content on the success of online crowdfunding proposals. Along with the increasing significance of ESG standards in business, investment proposals incorporating ESG concepts are now commonplace. Due to the ESG trend, conventional wisdom holds that the majority of proposals with ESG concepts will have a higher rate of success. We investigate by analyzing over 9000 online business presentations found in a Kickstarter dataset to determine which characteristics of these proposals led to increased investment. We first utilized lexicon-based measurement and Feature Engineering to determine the relationship between environment and society scores and financial indicators. Next, Logistic Regression is utilized to determine the effect of including environmental and social terms in a project's description on its ability to obtain funding. Contrary to popular belief, our research found that microentrepreneurs were less likely to succeed with proposals that focused on ESG issues. Our research will generate new opportunities for research in the disciplines of information science and crowdfunding by shedding new light on the environment of online micro-entrepreneurship.

'Hyesung' and 'Jeilsun' are media that reveal the new searches of the Gaebyeoksa Publishing Company of the 1930s. However, studies in the past did not sufficiently analyze their significance. Furthermore, there are no analyses on how the critical minds of 'Hyesung' and 'Jeilsun' were linked to 'Gaebyeok', which continued publications in 1934. The 1930s when 'Hyesung' and 'Jeilsun' were published, was a time where the media of colonial Chosun was rapidly changing, and it was a time where literary magazines were increasing in quantity. In the 1930s, Gaebyeoksa attempted to actively respond to such changes reflected in the media. This was demonstrated through the publication of the new media 'Hyesung' and 'Jeilsun' and continuing publication of the 'Gaebyeok' magazine in 1935. This study analyzed the literary discourses shown in the magazines published by Gaebyeoksa in the 1930s based on 'Hyesung', 'Jeilsun', and the continued publication of 'Gaebyeok'. Through such analysis, this study examined how the magazines published by Gaebyeoksa perceived the culture and literature of colonial Chosun in the 1930s and in which direction it tried to reorganize this.

Objective : The purpose of this study was to investigate the change in self-efficacy and writing ability after applying a Task-Oriented Multi-Sensory Movement Program to children with ADHD tendency accompanied by learning delays. Methods : A Task-Oriented Multi-Sensory Movement Program was implemented to children with ADHD tendency accompanied by learning delays attending S elementary school. The research proceeded in the order of a pre-test, Task-Oriented Multi-Sensory Movement intervention, and a post-test. The first session involved a pre-test, in which the children's self-efficacy and writing ability were examined using self-efficacy test and type 'A' KNISE-BAAT writing test. The multisensory group activity program intervention was conducted for a total of 8 sessions. In the last session, a post-test was conducted using self-efficacy test and type 'B' KNISE-BAAT writing test. Data collected from the tests were analyzed using SPSS Statistics 18. Results : According to the tests taken before and after implementing the Task-Oriented Multi-Sensory Movement Program, there was a significant improvement in self-efficacy (school, society), writing ability(command of vocabulary and sentence). Conclusion : Task-Oriented Multi-Sensory Movement Program may be used as a beneficial measure to improve the self-efficacy and writing abilities of children with ADHD tendency accompanied by learning delays. It is necessary to design various intervention models by combining educational media based on a multisensory approach.

Recently, semantic search techniques which are based on information space as consisting of nonambiguous, non-redundant, formal pieces of ontological knowledge have been developed so that users do exploit large knowledge bases. The purpose of the study is to design more user-friendly and smarter retrieval interface based on ontological analysis, which can provide more precise information by reducing semantic ambiguity or more rich linked information based on well-defined relationships. Therefore, this study, first of all, focuses on ontological analysis on researcher information as selecting descriptive elements, defining classes and properties of descriptive elements, and identifying relationships between the properties and their restriction between relationships. Next, the study designs the prototypical retrieval interface based on ontology-based representation, which supports to semantic searching and browsing regarding researchers as a full-fledged domain. On the proposed retrieval interface, users can search various facts for researcher information such as research outputs or the personal information, or carrier history and browse the social connection of the researchers such as researcher group that is lecturing or researching on the same subject or involving in the same intellectual communication.

Recently, school violence problem has increased serious. And this is not only an individual issue but also this is a social problem. Realistically, not only physical violence, cyber violence using the smartphone is very serious. And if the elementary school students are exposed to cyber violence, it becomes even more serious problem. Therefore, we proposed an Smart Monitoring app that protect the smart safety such as as a countermeasure against cyber violence to elementary school students. This Conversion Smart app can support grasp service for children using location based service on the smartphone when he will come to the home. And it can support another service that abuse or vulgar language in messenger. Grasps the degree of use of the language that is prohibited friendship in elementary school through this process, it can be derived. And we have future works that is the search rate and response time an inappropriate word on the proposed system.

과학영재교육의 중요한 목표중의 하나는 과학영재들의 과학에 대한 태도를 긍정적으로 변화시키는 것이다. 특히 태도와 같은 정의적 특성은 지적 특성에 비하여 후천적이고, 학습에 의해서 변화될 가능성이 크기 때문에(Marsh, 1990) 교육적으로 중요한 의미를 가지며 학생들이 성장하여 과학에 관련된 직업이나 활동을 하는 데 매우 중요한 역할을 한다(Oliver, W Hill, Pettus, W. C. and Hedin, B. A 1990). Anderson(1981)은 과학에서의 정의적 영역을 흥미, 태도, 가치, 통제의 소재, 학문적 자아개념, 불안, 선호 등의 7가지 영역으로 나누고 이 중에서 불안요인을 학업성취 및 태도에 가장 강하게 영향을 주는 요인으로 구분한 바 있다. 이처럼 과학 관련 태도나 과학 불안도는 학생들의 과학관련 활동이나 성취에 중요한 요인이 되고 있으나 이와 관련된 연구는 극히 미미하다. 지금까지의 태도 및 불안도에 관한 연구들은 일반학생들을 대상으로 하고 있으며 과학영재들을 대상으로 한 연구는 전혀 이루어지지 않았다. 따라서 본 연구는 과학영재교육원에 다니는 194명의 과학영재들을 대상으로 하여 과학영재 수업을 받은 후 과학 관련 태도와 과학 불안도가 변하는지, 과학 관련 태도와 과학 불안도는 어떠한 상관이 있는지, 그리고 남$\square$녀 집단의 차이가 있는지를 영재수업을 받기 전과 후의 검사를 통하여 알아보았다. 본 연구에서는 과학영재들의 과학 관켠 태도를 측정하기 위해‘고등학생을 위한 과학 관련 태도’검사를 사용하였다. 이 검사는 Fraser(1981)가 개발한‘TOSRA’(Test of Science-Related Attitudes)와 Munby(1983)의‘태도 측정 도구 조사’에서 문항 선정이 이루어졌다. 적절한 단어 및 어휘, 일부 문항들의 부적절한 환경 상황 등을 고려하여 40 문항 중 21문항을 수정하거나 삭제하고 문항내적 상관이 낮은 4문항을 제거하여 최종 30문항을 제시하였다(고유곤, 1996). 이 검사의 문항 내적 신뢰도 $\alpha$ 는 0.9 이었다. 검사 문항은 4개 범주과학에 대한 태도, 과학의 사회적 의미, 과학 교과에 대한 태도, 과학적 태도 등과 각 범주의 하위 문항으로 되어 있다 과학 불안도 측정 검사 도구는 중$\square$고등학생들의 과학불안도 측정을 위해 김범기(1993)가 개발한 것을 사용하였다.

Ideals of beauty has expressed variously through the centuries and in different cultures. Each traditional 'togu' has it's own morphology (in the meaning of nonverval linguistic) as using various type of language in each cultural erea. Korean aesthetics on 'dogu'philosophy introduces a whole new set of basic concepts outside western aesthetic framework of beauty Most distinctive is the insistence on overcoming dichotomies, especially between cognition and emotion, (momism)body and mind, self and other, and individual and group. Several topics are particularly illuminating within aesthetics: furniture, calligraphy, traditional garments pose interesting challenging to the art/nature, inside/outside, ethics/desire dichotomies so crucial to moral and cultural context. aesthetics are equally deserving of philosophical scrutiny: the ways in which philosophy of 'dogu'and aesthetics are integrated with daily life, the emphasis on process or understanding context rather than product itself or product 'form'. Dogu did not separate daily life and aesthetics from understanding social context. Language of 'togu' also has own vocabulary and grammar. But we often cannot gain our persnol experience truthful beauty of togu until understand context of understanding. it would be immpossible to explain ,or to analize different way of thinkings and behaivor precisly without understanding same codes of language.
