점점 더 많은 디지털 카메라와 휴대폰이 고해상도 카메라가 장착되고 대용량의 저장공간이 제공되면서 사용자들의 사진촬영 빈도가 증대하고 있다. 조만간 휴대폰의 저장된 사진을 효과적으로 관리하고 브라우징할 수 있는 기술이 필요한 시기가 올 것이다. 본 논문은 휴대폰이나 디지털 카메라 혹은 카메라가 장착되어 사진을 찍을 수 있는 모든 형태의 휴대단말에서 촬영된 개인사진을 지리적 위치정보를 이용하여 자동으로 분류하는 시스템을 제시한다. 기존의 시간정보를 이용하여 촬영시간의 근접성을 이용해 순차적으로 자동 분류하는 시스템과는 달리 위치정보를 이용하여 촬영위치에 따라 비순차적으로 자동 분류한다. 촬영위치 근접성을 결정하기 위해 밀도기반 클러스터링 알고리즘을 사용하여 전체 사진을 대분류하고 기존의 자동사진 분류방식에서는 다루지 않았던 일상사진과 비일상사진을 분류하고, 대분류된 사진을 시간정보를 이용하여 소분류 함으로서 자동 사진분류 성능을 높이고자 한다.

우리가 일상적으로 사용하는 말속에는 모호한 표현들이 많이 들어있다. 예를 들어, '젊다', '크다', '어느 정도' 등의 표현들은 정해진 값을 갖는 말들이 아니다. 가장 보편화된 RDBMS에서의 질의어인 SQL(Structured Query Language, 이하 SQL)은 데이터베이스에서 허용된 값, 즉 정량적인 값들에 대해서만 질의할 수 있도록 되어 있다. '젊은 여자' 혹은 '20세 정도의 여자'라는 질의는 할 수 없으며, '25세의 여자' 라는 식으로 정확한 질의만이 허용된다. 그러나 정보량이 급증하고 있고, 정보가 곧 힘이 되는 지금, 일반 사용자들도 데이터베이스에서 자신이 원하는 정보를 얻어 낼 수 있어야만 하게 되었다. 따라서 본 논문에서는 일반 사용자들도 데이터베이스에서 일상적으로 사용하는 단어(이하 자연어)로 질의를 할 수 있도록 하는 FSQL에 대해 논의하고자 한다.

우리나라가 급속도로 고령화 사회로 진입하여 감에 따라 의료비 등 국민적 부담이 크게 증가하고 있는 추세에 있다. 본 논문에서는 노인들의 삶의 질을 제고하고, 국가적으로는 노인의료비 부담을 경감시킬 수 있는 노인케어 유비쿼터스 시스템 u-SCS(Ubiquitous Senior Care System)에 대하여 연구하였다. 본 u-SCS 시스템은 조도 센서에서 감지한 조도값의 차이를 분석하여 실내의 노인이 불을 끄고 켜고 한 정보를 파악한다. 이러한 점등 및 소등 시간에 대한 분석은 노인의 수면 시간 등 일상적인 노인 행동을 인지할 수 있는 정보이므로, 이를 기초로 노인들이 겪을 수 있는 건강상 문제나 일상 생활의 불편함을 해소하는데 중요한 기초 정보로 활용할 수 있다.

모바일기기의 성능이 점차 발달함에 따라 모바일기기 내에서 로그데이터를 수집한 후 분석하여 사용자의 일상을 요약할 수 있게 되었다. 본 논문에서는 사용자의 GPS 위치정보, 사진 정보들을 모바일기기 내에서 수집하고 사진에 태깅된 사용자의 정보를 바탕으로 의사결정트리 알고리즘을 이용하여 사용자의 하루 일과를 요약한 모바일 사진 블로그를 생성하는 방법을 제안한다. 제안된 시스템으로 모바일기기만 이용하여 사용자의 일상을 효율적으로 요약하여 보여줄 수 있다.

Magazines also contain the daily lives of contemporary ordinary people. These characteristics serve as the possibility of daily archives. This study aims to build daily archives by analyzing the contents of the magazine Farmers' Life published in Daejeon for those archival values. To do that, it classified the articles that were published in Farmers' Life for 14 years from 1954 to 1967, it analyzed personal and organizational information, and also it implemented the daily life of farmers and rural society. The conclusion of the analysis on Farmers' Life summarized into following five points. First, the value of Daejeon private archives proved. Second, the personal information of people who were active in various fields of the society identified, and It classified by professional occupations such as politician, professor, agricultural scholar, doctor, and cartoonist, etc. Third, information on the organizations in the agricultural sector was able to collect that of some government organizations, public-private organizations, U.S. aids and 4H organizations. Fourth, certain evidence presented that help to correct the records that recorded wrongly or omitted or in need of speculation in the Christian Magazines, Literature and Art Fields. Fifth, the daily life of rural society and farmers classified into the series and organized into daily archives. This paper presented as a basic database to perceive the rural society and farmers' daily life in the 1950s and 1960s.

Three experiments were conducted to investigate whether different types (common vs. uncommon) of prior-examples entail different effects in creative problem solving, and whether types/levels (rich or lean. common or uncommon) of background knowledge interact with types of prior-examples. It was found that the example types and the types/levels of background knowledge do interact and have some differential effects on generating novel and useful ideas. In Experiment 1 and 2. uncommon examples had a positive effect - generating many novel and useful ideas. regardless of background knowledge types. while common examples had positive effects, only when the background knowledge was somewhat uncommon In Experiment 3 it was also found that types (irrelevant,. single common. single uncommon, or multiple common + uncommon) of background knowledge seemed to influence differently on the ease of finding solutions: when background knowledge is diverse or not directly related to the task problem, uncommon prior examples produced much greater number of novel ideas than it was with single common or sin91e uncommon background knowledge. Implications of the present study were discussed. in relation to mental sets and fixation.

This study aims to understand the everyday information-seeking behaviors of Alpha-generation elementary school students. A survey was conducted among 4th to 6th grade students to investigate their information needs in daily life, the sources they use to fulfill these needs and the reasons for their choices, the barriers they encounter during the information search process, and their satisfaction and trust in the information obtained. The results indicate that Alpha generation elementary students most frequently use video platforms and have the highest information needs related to hobbies and leisure activities. The main reasons for choosing information sources were familiarity and convenience. Differences based on demographic characteristics and media literacy education were also analyzed. There were significant differences in information-seeking behavior based on gender. Also, students who had received media literacy education experienced fewer difficulties in the information acquisition process compared to those who had not. The findings of this study are expected to provide valuable data for developing information services and media literacy education directions for the Alpha generation in school settings.

This study is to find ways to improve the daily life satisfaction of people with disability through interpersonal relation and self-efficacy. Descriptive statistics, correlation analysis and regression analysis by SPSS 21.0 were applied to 1,483 out of 4,400 of Penal Survey of Employment for the Disabled 2nd Wave. The study show that the interpersonal relation had a positive effect on self-efficacy and daily life satisfaction. Self-efficacy influenced positive effect to life satisfaction and played a mediating role between interpersonal relation and daily life satisfaction. Based on the conclusion that daily life satisfaction can be enhanced through the improvement of interpersonal relations and self-efficacy, this study made policy suggestions to improve interpersonal relations and self-efficacy.

The purpose of this study was to provide basic data for the development of fall prevention programs for the elderly and for improvement of quality of life based on history of falls, chronic diseases, location, fear of falling, daily living activities, and quality of life. This study was conducted from 15th August to 17th September of 2016 on 185 elderly subjects above the age of 65 living in four centers of J city and four centers of J rural. The results of this study are as follows: There were no statistically significant differences in daily living activities, fear of falls, and quality of life regarding falls in the past. There were statistically significant differences in fear of falling and quality of life regarding chronic diseases. There were statistically significant differences in daily living activities and quality of life regarding residence. This study confirms that there were relations among daily living activities, fear of falling, and quality of life, and there was a negative correlation between fear of falling and accomplishment of daily living activities(r=-.386, p<.000). There was also a positive correlation between accomplishment of daily living activities and quality of life(r=.513, p<.000). Therefore, avoiding outings on slippery roads and creating safe environments for the elderly are important to reduce fear of falling. Additionally, a system should be developed for the elderly to acquire necessary information for daily life.
