In a planning stage, the assessment system is required to select the proper alternative, reflected the environmental affects such as energy, $CO_2$ and $SO_x$. Unit of energy consumption, $CO_2$ emission and $SO_x$ emission among various assessment systems could be effectively utilized to select the better alternative among various building types. But researches for these areas has not been conducted systematically, but limitedly and sporadically. In this paper, it aimed at providing the unit of energy consumption, $CO_2$ emission and $SO_x$ emission to evaluate the environmental affects between the steel-structured apartment building and wall-typed apartment building. For this, the input-output analysis could be utilized in the construction stage with two-type apartment housing. This approach can be utilized to compare the various alternatives in aspect of the energy consumption and the environment affect, and to select the relatively better alternative. This study found that the unit of energy, $CO_2$ and $SO_x$ of the steel-structured apartment building is lower than that of the wall-typed building

This study examined structured social network types and their relationship to quality on life satisfaction of older adults. Respondents were 418 adults aged 60 or older living alone or as couples. The data was analyzed using K-means cluster analysis. Four networks types were identified: diverse, friend-neighbor focused, family focused, and restricted. Life satisfaction was highest for individuals in the diverse network group and lowest for individuals in the restricted network group. Stepwise multiple regression analysis indicated that life satisfaction of the elderly was affected by the diverse network, family focused network, the relationship quality with children, the relationship quality with neighbors, and the relationship quality with relatives. Results suggested that having diverse social network in close proximity is very important in old age and structural network types may have important practical implications for improving the quality of life among the elderly.

직업훈련 교육 현장에서 느끼는 가장 큰 어려움 중 하나는 중도탈락 문제이다. 훈련과정마다 많은 수의 학생들이 중도탈락을 하게 되어 국가 예산 낭비 및 청년 취업률 개선에 장애 요인이 되고 있다. 본 연구에서는 중도탈락의 원인을 주로 분석한 기존 연구들과 달리, 각종 수강생 정보를 활용하여 사전에 중도탈락을 예측할 수 있는 기계학습 기반 모형을 제안하고자 한다. 특히 본 연구의 제안모형은 수강생 관련 정형 데이터 뿐 아니라 비정형 데이터인 강사의 상담일지 정보까지 동시에 고려하여 모형의 예측정확도를 제고하고자 하였다. 이 때 비정형 데이터에 대한 분석은 최근 주목받고 있는 텍스트 분석 기술인 Word2vec과 합성곱 신경망을 이용해 수행하였다. 국내 한 직업훈련기관의 실제 데이터에 제안모형을 적용해 본 결과, 정형데이터만을 사용하여 중도탈락을 예측할 때보다 비정형 데이터를 함께 고려했을 때 예측의 정확도가 최대 20%까지 향상됨을 확인할 수 있었다. 아울러, Support Vector Machine을 기반으로 정형 데이터와 비정형 데이터를 결합해 분석했을 때, 검증용 데이터셋 기준으로 90% 후반대의 높은 예측 정확도를 나타냄을 확인하였다.

정부 및 공공기관에 있어 시민의 직접적인 요구사항이 담겨 있는 민원은 정책 개발을 위한 중요한 데이터로 활용이 가능하다. 그러나 민원 데이터는 비정형 텍스트로 작성되어 있는 특성으로 인해 일반적인 텍스트 마이닝 기법으로는 시민의 요구사항을 정확히 도출하기 어려웠다. 이에 본 연구에서는 민원 데이터 분석을 위한 텍스트 마이닝 기법을 개선하여, 시민의 요구사항을 도출할 수 있는 방법을 제시하고자 하였다. 새로운 텍스트 마이닝 기법은 공기어구조맵의 원리에 착안하여 연관성 분석을 2단계로 실시하여 핵심주제어를 기반으로 1차 연관 단어 와 2차 연관 단어로 구조화하였다. 분석을 위해 2016년 1년간 부산시 민원게시판에 올라온 3004건을 활용하였다. 분석 결과는 빈도수와 핵심주제어를 가지고 연관성 분석만으로는 찾을 수 없었던 민원 상의 문제를 본연구에서 제시한 계층적 연관성 분석을 이용하여 시민의 요구사항을 더욱 정확하게 파악할 수 있었다. 본 연구는 민원 데이터에서 시민의 요구사항을 도출하기 용이한 방법을 제안하였다는 학문적 기여점이 있으며, 행정기관에서 민원 데이터를 통해 정책 개발에 활용할 수 있다는 실무적 기여점이 있다.

Gene-gene interaction (GGI) analysis is known to play an important role in explaining missing heritability. Many previous studies have already proposed software to analyze GGI, but most methods focus on a binary phenotype in a case-control design. In this study, we developed "Hierarchical structural CoMponent analysis of Gene-Gene Interactions" (HisCoM-GGI) software for GGI analysis with a continuous phenotype. The HisCoM-GGI method considers hierarchical structural relationships between genes and single nucleotide polymorphisms (SNPs), enabling both gene-level and SNP-level interaction analysis in a single model. Furthermore, this software accepts various types of genomic data and supports data management and multithreading to improve the efficiency of genome-wide association study data analysis. We expect that HisCoM-GGI software will provide advanced accessibility to researchers in genetic interaction studies and a more effective way to understand biological mechanisms of complex diseases.
