차세대 염기서열 분석이 개발되고 널리 사용됨에 따라 RNA-시퀀싱(RNA-sequencing, RNA-seq)이 글로벌 전사체 프로파일링을 검증하기 위한 도구의 첫번째 선택으로 급부상하게 되었다. RNA-seq의 상당한 발전으로 다양한 유형의 RNA-seq가 생물정보학(bioinformatics) 발전과 함께 진화했으나, 다양한 RNA-seq 기법 및 생물정보학에 대한 전반적인 이해 없이는 RNA-seq의 복잡한 데이터를 해석하여 생물학적 의미를 도출하기는 어렵다. 이와 관련하여 본 리뷰에서는 RNA-seq의 두 가지 주요 섹션을 논의하고 있다. 첫째, Standard RNA-seq과 주요하게 자주 사용되는 두 가지 RNA-seq variant method를 비교하였다. 이 비교는 어떤 RNA-seq 방법이 연구 목적에 가장 적절한지에 대한 시사점을 제공한다. 둘째, 가장 널리 사용되는 RNA-seq에서 생성된 데이터 분석; (1) 탐색적 자료 분석 및 (2) enriched pathway 분석에 대해 논의하였다. 데이터 세트의 전반적인 추세를 제공할 수 있는 주 성분 분석, Heatmap 및 Volcano plot과 같이 RNA-seq에 대해 가장 널리 사용되는 탐색적 자료 분석을 소개하였다. Enriched pathway 분석 섹션에서는 3가지 세대의 enriched pathway 분석에 대해 소개하고 각 세대가 어떤 식으로 RNA-seq 데이터 세트로부터 enriched pathway를 도출하는지를 소개하였다.

The purpose of this study was to investigate the status of domestic and foreign power blogs that serve as professional source of information and to clarify the difference of the criteria for the certification and selection of power blogs. The study also analyzed the configuration of contents and the characteristic of categories of the power blogs. Eleven domestic blogs were examined, of which ten were certified as power blogs on several portal sites and one blog was operating in English. Furthermore twelve foreign blogs were examined, of which ten blogs were selected from the graded list of www.alexa.com for the Fashion Power Blog TOP 20 adopted on www.telegraph.co.uk in 2009, and two noticeable blogs were selected additionally. Data were analyzed by both theoretical and exploratory studies. The exploratory study was conducted by fourteen majors, who took interest in the blogs and were divided into two groups to look at the domestic and foreign sites, from 12 October to 12 November in 2010. The types of blogs were classified by frequency analysis of interactivity, interest provision, information provision and purchase capability. The investigators checked the type of the contents of each blog and the frequencies were used for the classification type. The analysis showed that the frequencies were in the order of information provision, followed by interest provision, and purchase capability for foreign blogs, while interest provision was followed by information provision for domestic blogs. Interactivity, interest provision, information provision and purchase capability were generally reflected in foreign blogs. Rather than interest provision and information provision, however, interactivity and purchase capability were reflected relatively weakly in domestic blogs.

Purpose: The Life Transition Scale (LTS) consists of 24 items that assess the life transition process of parents of autistic children. This study aimed to examine the validity and reliability of the LTS in parents of children with a wide spectrum of disabilities. Methods: Data were collected from 260 parents of children with disabilities through self-report questionnaires. Validity was examined using exploratory and confirmative factor analysis to determine the factor structures of the LTS; socio-demographic differences in LTS scores were examined using the t-test or ANOVA. Reliability was examined using Cronbach's α coefficient. Results: A four-factor structure was validated (χ²=640.0, p<.001, GFI=.81, RMSEA=.07, NNFI=.89, CFI=.89, PNFI=.74, Q [χ²/df]=2.60). The validity of the LTS was verified by exploratory factor analysis, with factor loading ranging from .30 to .80. There were significant differences in the accepting phase according to children's and parents' age and the type of disability, and in the wandering phase according to parental gender, educational level, job, and socioeconomic status. The Cronbach's αs for the reliability of each of the four structures were acceptable, within a range of .80~.90. Conclusion: The LTS is a valid and reliable measurement to assess the life transition process of parents with disabled children.

Background: It is important to validate scales related to cancer screening beliefs in order to better understand perceptions. The aim of this study was to test the psychometric properties of the colorectal cancer screening belief scale based on Health Belief Model (HBM) constructs. Materials and Methods: Data were collected from 600 persons referred to outpatient laboratory units in Iran through a convenience sampling procedure. In this cross-sectional study, exploratory and confirmatory factor analyses were used to examine construct validity of scale. Results: Through exploratory factor analysis, 52 items of the scale converged to five constructs of HBM with 4 items omission. Construct validity was determined by confirmatory factor analysis through which correlated model was supported. Cronbach's alpha coefficient for the whole scale was obtained as 0.78, which indicates reliability of the scale. Conclusions: The study findings showed that this scale is a valid and reliable instrument that can be used for measuring HBM constructs about colorectal cancer screening with the fecal occult blood test.

The purpose of this study was to investigate three different perceptions based on major 23 part planning attributes. These party planning attributes were categorized using exploratory factor analysis. Three groups of respondents were identified based on the sample data; the first group is a group of people experienced parties before, the second group is a group of people intended to attend parties in near future, and the third group is a group of people who want to be a party planner. Respondents participated in this study express their own perceptions on party-planning attributes. The study shows that the perceptions of respondents were significantly different from each other. Particularly, prospective party planners emphasize on artistic attributes, such as harmony between dishes and foods or between the party concept and foods. However, party attendees more importantly considered other attributes, including the event suitable to the party type, places held a party. The research suggests that understanding party attendees' perception will provide useful information to develop party events that can reflect customers' desires.

The purpose of this study is to explore the interior therapy that introduced the concept of therapy into interior space. This study examines interior therapy based on the concepts of stress and therapy. As the study methods, a qualitative analysis to review the concept of interior therapy was conducted together with a quantitative analysis on the current state of domestic therapy-related researches. The scope of the study is limited to domestic journals published from 1988, when the first domestic research was embarked on to analyze the current status of therapy-related researches, until November 2016. According to the study results, the domestic therapy-related studies were mainly focused on aromatherapies and food therapies. By year, the first domestic study of its kind was conducted on logotherpay in 1988. And until 2000, studies were carried out mainly on aromatherapies. Since then, new psychotherapy research fields have emerged; color therapy in 2003 and food therapy in 2008. However, in the space design field except for color therapy-related researches, there have been not sufficient studies on the indoor space therapy field that investigates the possibility of indoor space as a therapy from an integrated viewpoint. Therefore, this study reviewed domestic researches on interior therapy which applied the concept of therapy to interior design and suggested three cognitive-emotional-behavioral measures as healing factors. Finally, this study is expected to be used as basic data for design planning and curriculum development which apply the concept of therapy to interior design-related fields.
