The purpose of this study is investigated on the loneliness of childhood and related variables. 400 boys and girls were sampled far this study that they are elementary school 5th 6th located in IK-San, Kim-Je city. Survey was conducted by self-reported questionnaires and 380 questionnaires were finally used for the data analysis. The data analysis with SPSS Computer program were frequency, percentage, mean, 7- 1est, one-way ANOVA with Duncan's Multiple Range test and Multiple Regression Analysis. The results of this study can be summarized as follows : 1. Significant difference was founded in children's loneliness according to father's education, father's job mother's education, school grade, name satisfaction, body satisfaction, siblings, close relation friend number, family harmony, parent's love- acceptable. 2. Significant difference was founded in children's loneliness according to peer status degree (popular isolation aggression). Higher popular children was perceived lower in loneliness than lower popular children. Higher isolation children was perceived higher in loneliness than lower isolation. Higher aggression children was perceived higher in loneliness than lower aggressive in loneliness. 3. In the result of multiple regression analysis the influence on the loneliness be presented as follows in order of importance , peer status of isolation degree popular degree mother's job of self business, parent's love-acceptable, friends number. The result the above study indicates that peer status family harmony, parent's love- acceptable, child's psychological environmental variables influences on the loneliness but essential variables are influences peer status on the loneliness.

일반적으로 사람들은 자신들이 갖는 국적에 따라 분류되지만, 각 개인의 문화적 경향은 반드시 자신들이 속한 국적에 의해 결정되지 않는다. 오히려 하나의 문화적 배경을 가진 사람이라 하더라도 자신이 속한 하위문화에 따라 자신의 정체성과 다양성이 형성된다. 본 연구는 힙합 장르 노래에 대한 분석을 통해 미국, 독일, 한국의 하위문화적 속성을 밝혔다. 이를 위해 음원 판매액과 힙합의 역사에 관한 기존 연구를 토대로 각 국가에서 힙합이라는 장르가 출현한 시점 및 2016년의 가장 인기 있었던 노래를 각각 한 곡씩 총 여섯곡을 선정해 기호학적으로 분석했다. 국가별 힙합의 초기 및 현재 모습에 대한 비교 분석결과, 흥미롭게도 힙합은 대상에 대한 묘사에 있어 점점 유사해져 가는 동시에, 더욱 개인주의적 경향을 띠고 있음을 공통적으로 지니고 있다. 그러나 세부적인 측면에서 각 국가 간 차이가 발견되었다. 미국 힙합에서는 대표적으로 아메리칸 드림(American Dream)에 대한 열망이 드러났으며, 독일의 힙합에서는 과도한 남성성 이미지가 강조되었다. 한편, 한국 힙합은 보다 일상적인 생각과 이야기를 중심으로 전개되는 양상을 띠었다. 나아가 비록 사회 비판의 도구로서 힙합이 갖는 중요도가 점차 감소하고는 있지만, 여전히 힙합은 강력한 문화적 반항이자 새로운 도전의 상징으로 인식되고 있다.

We compare two popular algorithms in current machine learning and statistical learning areas, boosting method represented by AdaBoost and kernel based SVM (Support Vector Machine) using 13 real data sets. This comparative study shows that boosting method has smaller prediction error in data with heavy noise, whereas SVM has smaller prediction error in the data with little noise.

Caloric restriction is a popular approach to treat obesity and its associated chronic illnesses but is difficult to maintain for a long time. Intermittent fasting is an alternative and easily applicable dietary intervention for caloric restriction. Moreover, intermittent fasting has beneficial effects equivalent to those of caloric restriction in terms of body weight control, improvements in glucose homeostasis and lipid profiles, and anti-inflammatory effects. In this review, the beneficial effects of intermittent fasting are discussed.

스마트폰의 대중화로 모바일기기에서의 음악을 듣기 위한 스트리밍 서비스가 주요시 되고 있다. 애플 iOS에서는 Apple의 HTTP Live Streaming 방식을 사용하고 안드로이드에서는 RTSP(Real-time Streaming Protocol) 방식을 사용한다. 모바일 실시간 스트리밍을 지원하기 위해 와우자 미디어 서버를 사용하게 되는데, 이는 애플과 안드로이드 모바일 스트리밍 모두를 지원한다. 본 논문에서는 스마트폰 자체의 녹음 기능을 통해 유저 스스로가 노래를 녹음하고, 이를 스트리밍 서버에 업로드 하여 유저가 선택한 노래를 실시간으로 스트리밍 모바일 재생 서비스가 가능하고, 노래공유 SNS 기능을 제공하는 스마트폰 앱의 설계 및 구현에 대해 기술하고자 한다.

A finger language helping hearing impaired people in communication A sign language helping hearing impaired people in communication is not popular to ordinary healthy people. In this paper, we propose a method for real-time sign language recognition from a vision system using color information and fuzzy clustering system. We use YCbCr color model and canny mask to decide the position of hands and the boundary lines. After extracting regions of two hands by applying 8-directional contour tracking algorithm and morphological information, the system uses FCM in classifying sign language signals. In experiment, the proposed method is proven to be sufficiently efficient.

Exponential L$\acute{e}$evy models have become popular in modeling price processes recently in mathematical finance. Although it is a relatively simple extension of the geometric Brownian motion, it makes the market incomplete so that the option price is not uniquely determined. As a trial to find an appropriate price for an option, we suppose a situation where a hedger wants to initially invest as little as possible, but wants to have the expected squared loss at the end not exceeding a certain constant. For this, we assume that the underlying price process follows a variance-gamma model and it converges to a geometric Brownian motion as its quadratic variation converges to a constant. In the limit, we use the mean-variance approach to find the asymptotic minimum investment with the expected squared loss bounded. Some numerical results are also provided.

본 연구는 기부문화에 대한 일반 대중들의 인식의 변화를 위해 누구나 손쉽게 다가갈 수 있는 게임을 제안하며, 이를 모바일 앱으로 구현하고자 한다. 본 연구에서 제안하는 앱은 NGO 단체들의 대표적인 온라인 활동 중의 하나가 될 수 있으며, 노래 게임를 이용하기 때문에 기부에 대한 부담보다는 재미를 느낄 수 있는 게임 앱이다. 본 연구를 통해 다양한 게임 형태의 기부 앱이 많이 활성화되며, NGO단체나 기업, 그리고 SNS를 통해 대중적인 기부문화 정착에 이바지 할 것으로 기대된다.

It is requures to understand the meaning of sound and cultural background of target spaces for soundscape design. The purpose of this study is to derive the general soundscape preserved in the mind of Korean people. Four kinds of traditional Korean songs, that is to say, Sijo (Korean verse), folk-song, Pansori (song for drama by Chang reciter), and popular songs, were used as tools of research subjects. That is because the sounds expressed in literature are very useful subjects for soundscape survey. Paragraphs containing description of sounds were selected from the lyrics of the songs. Then 11 sound categories were named, and 13 meaning categories were classified according to referential and emotional aspects, respectively.

This paper studied the origin of Myeongnyundang(明倫堂), the common name of the main lecture halls at confucian schools in ancient China. Through an extensive investigation of local chronicles, biographies, decrees and construction essays, it found the first Myeongnyundang were titled on the main hall of a local school in the early Southern Song(南宋) period, and it might become the most popular name due to Zhuxi (朱熹), a famous confucian scholar in the Southern Song dynasty. In Yuan(元) period, it almost become the fixed name for the main lecture hall at local confucian schools, and even the official government documents began to use it as a common noun since the beginning of Ming(明) dynasty.
