제품의 사용자 인터페이스를 개발하기 위해서는 해당 제품의 사용 행태를 정확하게 파악하는 것이 핵심적이다. 사용자 행태에 관한 정보를 수집하는 방법으로는 설문이나 개별/집단 면접 등이 흔히 사용되고 있으나, 이는 사용자들의 기억에 의존하는 간접적인 방법이기 때문에 그 정확성을 보장할 수 없다는 것이 단점으로 지적된다. 이 연구에서는 사용자 조작 로그(Log)를 기록, 수집하는 방법을 활용하여 가전 제품의 사용 행태에 대한 정보를 직접적으로 파악하였고 그 결과를 바탕으로 사용자 중심 인터페이스 디자인을 개발하고자 하였다. 디지털TV실사용자 가구들을 조사 대상으로 선발한 후 해당 가정의 실제 사용 환경에서 약 1개월간 사용 로그를 기록하였다. 로그 수집과 함께 면접 설문도 실시하였다. 수집된 로그를 통계적으로 분석하여 제품의 주요 기능별 사용 빈도와 패턴을 추출해 낼 수 있었다. 이 결과를 면접에서 대상자들이 응답한 내용과 비교하여 간접 조사 방법의 정확도를 검증해 보았다. 로그 분석 결과에서 도출된 사용 행태 데이터를 근거로 사용자 맞춤 인터페이스 기능을 제안하였다. 또한 각 가구별 결과를 2차 분석하여, 사용 행태 데이터를 기반으로 한 사용자 세분화(Segmentation)를 하였고 각 세그먼트(Segment)별 주요 특징을 도출해 낼 수 있었다. 이러한 여러 분석 결과는 가전 제품의 사용자 중심 인터페이스 개발에 사용 Log분석이 활용될 다양한 가능성과 유용성을 보여주었다.

This study was conducted to obtain basic information on growth characteristics and major components of three Korean endemic resource plant species, Artemisia sp., Gynostemma pentaphyllum Makino and Humulus japonicus S. et Z. , growing in different areas in Korea. Three geographical types of artemisia, namely Pangssuk, Ongjinssuk and Yakssuk which were collect in Suwon, Ongjin and Eumsong, respectively were compared in yield, and Pangssuk artemisia was higher in yield than the others. However, essential oil content was the highest in Yakssuk artemisia. Dry weight of areal parts of G. pentaphyllum was higher in the cultural method with props for tendril growth than in the conventional cultural method without props. Rutin was detected in areal parts of G. pentaphyllum. Dry weight of areal parts of H. japonicus collected at the Kyeryong mountain in Chungnam province was higher than that collected in Eumsong. A phenolic compound isoquercitrin was detected in areal parts of H. japonicus.

The improvement of superior black soybeans could be accomplished through maintenance and use of black soybean collections. This experiment was carried out to select pure-line from the domestic black soybean genotypes, and survey some agronomic characteristics of the collections. Nine hundred and sixty five lines of black soybeans were collected in 197 locations on spring, 1991. Higher distribution was present in broad leaves, purple flower color and tawny pubescence color which were approximate to be 97, 90 and 98%, respectively. In pod color of black soybean collections, 60% was brown and 27% was light brown and 10% was dark brown. The 61 to 70 days were required for flowering in 61 % of the collections. Growing days of 51 % of black soybean collections ranged 121 to 130, and those of 37 % were over 131 days.

The purpose of this study was to investigate the effects of leader-member exchange(LMX), participation in the opportunities for competency development, and subjective career success. LMX and participation in the opportunities for competency development were the independent variables and the subjective career success was used as control variable. Based on the data collected from 257 employees of a Korean financial company, correlation analysis and multiple regression analysis were conducted through the using SPSS/WIN 20.0 statistical package program. The results showed the statistically significant correlation between employability and other research variables. Also, results identified that participation in the opportunities had largest influence on the employability and LMX had no significant effects on the employability. The discussion and proposition for the future studied were provided.

This study proposed a model to estimate traffic accident likelihood using real-time traffic data obtained from freeway traffic surveillance systems. Traffic variables representing spatio-temporal variations of traffic conditions were utilized as independent variables in the proposed models. Binary logistics regression modelings were conducted to correlate traffic variables and accident data that were collected from the Seohaean freeway during recent three years, from 2004 to 2006. To apply more reliable traffic variables, outlier filtering and data imputation were also performed. The outcomes of the model that are actually probabilistic measures of accident occurrence would be effectively utilized not only in designing warning information systems but also in evaluating the effectiveness of various traffic operations strategies in terms of traffic safety.

As the employment situation has become increasingly severe in recent years, the employment pressure has become intense. How to improve the employability of university students has become the focus of public attention. This study aims to investigate that hope moderates the mediating role of entrepreneurship education in the relationship between career exploration and employability. The purposive sampling method was applied to the sampling of the survey subjects from Guangdong Province, China. A total of 346 questionnaires on career exploration, hope, entrepreneurship education and employability were collected and analyzed. The collected data was analyzed using SPSS PC+ Mac ver. 26.0 and SPSS PROCESS macro ver. 4.2. The statistical methods applied were frequency analysis, corelation analysis, and moderated mediation effect analysis. The conclusion of the study is as follows. First, career exploration had a significant positive correlation with entrepreneurship education, hope and employability. Second, hope showed the moderated mediation effect on the mediating role of entrepreneurship education in the relationship between career exploration and employability. This study suggesed a plan to utilize career exploration, entrepreneurship education and hope to increase college students' employability.

In this paper, we design a facial facial image data collection system for heart rate measurement using a web camera. The design content of this paper is a function of collecting user face image information using a web camera and measuring heart rate using the user's face image information. There is a possibility that an error may occur due to non-contact heart rate measurement using a web camera. Therefore, in this paper, it is to be used for correcting heart rate program errors through classification of data in cases of error and normal. The data in case of error can be used for the purpose of reducing the error. Experiments were conducted on the proposed ideas and designed in this paper. As a result of the experiment, it was confirmed that it operates normally.

The improvement of superior black soybeans could be accomplished through maintenance and use of black soybean collections. A collection of 965 black soybean lines currently grown by farmers was made in 197 locations on spring, 1991. This study was carried out to evaluate them as useful germplasm. Seed characteristics of black soybean collections were evaluated for black soybean breeding for seed quality. The 100-seeds weight of 929 black soybean genotypes were distributed from 6.9 to 48.1 gram. The maximum and minimum 100-seeds weight were derived from Chungnam and Jeonbuk province, respectively. l00-seeds weight was heavier in middle and late maturity group, as maturity was later, whereas no tendency was shown in early maturity group. Length, width and thickness of the collected black soybean seeds were 9.5$\pm$1.5mm, 7.3$\pm1.3mm and 7.3$\pm1.2mm, respectively. Black soybean collections with yellow seed embryo was 72% and the others were green seed embryo.

'서치 방지 단어'는 SNS 상에서 사용자들이 작성한 문서의 검색 및 수집을 피하기 위하여 사용하는 변이형을 뜻한다. 하나의 검색 키워드가 있다면 그와 같은 대상을 나타내는 변이형이 여러 형태로 존재할 수 있으며, 이들 변이형에 대한 검색 결과를 함께 수집할 수 있다면 데이터 확보가 중요하게 작용하는 다양한 연구에 큰 도움이 될 것이다. 본 연구에서는 특정 단어가 주어진 키워드로부터 의미 벡터 상의 거리가 가까울수록, 그리고 주어진 키워드와 비슷한 음성적 형태 즉 발음을 가질수록, 해당 키워드의 변이형일 가능성이 높을 것이라고 가정하였다. 이에 따라 단어 임베딩을 이용한 의미 유사도와 최소 편집 거리를 응용한 음성적 유사도를 이용하여 주어진 검색 키워드와 유사한 변이형들을 제안하고자 하였다. 그 결과 구성된 변이형 후보의 목록에는 다양한 형태의 단어들이 포함되었으며, 이들 중 다수가 실제 SNS 상에서 같은 의미로 사용되고 있음이 확인되었다.
