이 연구의 목적은 4년제 대학 인문·사회계열 졸업자의 복수전공 이수 여부 및 전공과 일의 일치 정도가 첫 일자리 취업성과에 미치는 영향을 분석하는 것에 있었다. 이를 위해 한국고용정보원에서 제공하는 대졸자직업이동경로조사(GOMS) 2019년 자료를 활용하여 취업성과를 임금, 정규직 취업 여부, 일자리 만족도로 구분하여 위계적 회귀분석을 실시하였고 그 결과는 다음과 같이 나타났다. 첫째, 4년제 대학 인문·사회계열 졸업자 중 취업자의 복수전공 이수 비율은 22.4%로 나타나 복수전공 이수율이 높지 않은 것으로 나타났다. 둘째, 주전공과 일의 일치 정도가 2.83점으로 보통 수준에도 미치지 못하는 것으로 나타났다. 셋째, 첫 일자리의 취업성과인 정규직 여부와 임금, 일자리 만족도에 성별과 졸업학점이 유의한 영향을 미치는 것으로 나타났으며, 대학시절 인턴과 직업훈련 경험이 있는 경우 첫 일자리가 정규직일 가능성이 높았고 더 높은 임금을 받는 것으로 나타났다. 넷째, 복수전공 이수 여부, 주전공과 일의 일치 정도, 복수전공과 일의 일치 정도는 일자리 만족도에 영향을 미치는 것으로 나타났다. 이는 단순한 복수전공의 이수 여부보다는 복수전공과 일자리의 일치 정도가 포함되었을 때 복수전공의 이수 여부가 일자리 만족도에 유의한 결과를 보여주고 있어 복수전공 선택 시 자신의 진로에 맞추어 전공을 선택할 필요가 있음을 시사한다. The purpose of this study was to analyze the impact of whether graduates in humanities and social sciences from four-year universities completed a double major and the degree of alignment between their major and job on their initial employment outcomes. To achieve this, hierarchical regression analysis was conducted using the data from the 2019 Graduates Occupational Mobility Survey (GOMS). The major findings were as follows. First, among graduates in humanities and social sciences from four-year universities, the proportion of employed individuals with a double major was 22.4%, indicating a relatively low rate of double major completion. Second, the degree of alignment between the major and job was 2.83 points, falling short of a moderate level. Third, gender and GPA significantly influenced the initial employment outcomes, including regular employment status, wages, and job satisfaction. Those who had internship and vocational training experiences during their university years were more likely to secure regular employment and receive higher wages in their initial jobs. Fourth, the completion of a double major, the degree of alignment between the major and job, and the degree of alignment between double major and job were found to influence job satisfaction. This suggests that, rather than simply completing a double major, aligning the double major with the job is crucial for job satisfaction. It implies the importance of selecting majors in line with one’s career path when choosing a double major.

<P>Environmental contamination by trinitrotoluene is of global concern due to its widespread use in military ordnance and commercial explosives. Despite known long-term persistence in groundwater and soil, the toxicological profile of trinitrotoluene and other explosive wastes have not been systematically measured using in vivo biological assays. Zebrafish embryos are ideal model vertebrates for high-throughput toxicity screening and live in vivo imaging due to their small size and transparency during embryogenesis. Here, we used Single Plane Illumination Microscopy (SPIM)/light sheet microscopy to assess the developmental toxicity of explosive-contaminated water in zebrafish embryos and report 2,4,6-trinitrotoluene-associated developmental abnormalities, including defects in heart formation and circulation, in 3D. Levels of apoptotic cell death were higher in the actively developing tissues of trinitrotoluene-treated embryos than controls. Live 3D imaging of heart tube development at cellular resolution by light-sheet microscopy revealed trinitrotoluene-associated cardiac toxicity, including hypoplastic heart chamber formation and cardiac looping defects, while the real time PCR (polymerase chain reaction) quantitatively measured the molecular changes in the heart and blood development supporting the developmental defects at the molecular level. Identification of cellular toxicity in zebrafish using the state-of-the-art 3D imaging system could form the basis of a sensitive biosensor for environmental contaminants and be further valued by combining it with molecular analysis.</P>

Encapsulation performance of Maillard reaction products (MRPs) produced by whey proteins and maltodextrin were examined for microencapsulation of conjugated linoleic acid (CLA) using spray-drying. CLA was encapsulated using 3 different wall materials containing a single constituent such as whey protein concentrate (WPC), whey protein isolate (WPI), and maltodextrin (MD), and 4 different MRPs. For the development of MRPs, ratios of WPC to MD were 1:2 and 1:3, whereas those of WPI to MD were 1:5 and 1:10. CLA and wall material were mixed and homogenized, and then spraydried. The physical properties of encapsulated CLA powders were characterized by particle size and morphology, ζ-potential, flowability, solubility, and dispersibility. The CLA powders coated with WPI-based MRPs have better encapsulation efficiency, water solubility, and smaller particle size than those coated with WPI, WPC, or MD alone. These encapsulated CLA powders have a number of possible utilities as ingredients in a variety of foods.

Precise 3D spatial mapping of cells and their connections within living tissues is required to fully understand developmental processes and neural activities. Zebrafish embryos are relatively small and optically transparent, making them the vertebrate model of choice for live in vivo imaging. However, embryonic brains cannot be imaged in their entirety by confocal or two-photon microscopy due to limitations in optical range and scanning speed. Here, we use light-sheet fluorescence microscopy to overcome these limitations and image the entire head of live transgenic zebrafish embryos. We simultaneously imaged cranial neurons and blood vessels during embryogenesis, generating comprehensive 3D maps that provide insight into the coordinated morphogenesis of the nervous system and vasculature during early development. In addition, blood cells circulating through the entire head, vagal and cardiac vasculature were also visualized at high resolution in a 3D movie. These data provide the foundation for the construction of a complete 4D atlas of zebrafish embryogenesis and neural activity.
