Understanding the crosstalk mechanisms between perivascular cells (PVCs) and cancer cells might be beneficial in preventing cancer development and metastasis. In this study, we investigated the paracrine influence of PVCs derived from human umbilical cords on the proliferation of lung adenocarcinoma epithelial cells (A549) and erythroleukemia cells (TF-1α and K562) in vitro using TranswellⓇ co-culture systems. PVCs promoted the proliferation of A549 cells without inducing morphological changes, but had no effect on the proliferation of TF-1α and K562 cells. To identify the factors secreted from PVCs, conditioned media harvested from PVC cultures were analyzed by antibody arrays. We identified a set of cytokines, including persephin (PSPN), a neurotrophic factor, and a key regulator of oral squamous cell carcinoma progression. Supplementation with PSPN significantly increased the proliferation of A549 cells. These results suggested that PVCs produced a differential effect on the proliferation of cancer cells in a cell-type dependent manner. Further, secretome analyses of PVCs and the elucidation of the molecular mechanisms could facilitate the discovery of therapeutic target(s) for lung cancer.

The purpose of this study is intended to identify the mediated moderating effect including the mediating effect of job satisfaction and moderating effect of job expectations in the relation between work value, job satisfaction, In this study, the mediating effect of job satisfaction and job preference on the relationship between job value and quality of life were investigated. In this study, questions to measure job value, job satisfaction, and job preference were examined using GOMS data, and data analysis was performed using SPSS 23.0 and SPSS Macro. Since the mediated moderation model is an integrated model that includes mediating and moderating effects, the mediating effect, the moderating effect, and the mediated moderation effect were sequentially verified. As a result of the study, first, it was confirmed that the mediating effect model through job satisfaction was statistically significant. Next, it was confirmed that job value had a statistically significant effect on life satisfaction through the direct path and the indirect path through job satisfaction as a mediating variable. Third, it was confirmed that the moderated mediating effect model of job preference through job satisfaction was statistically significant. In detail, job value as an independent variables and job satisfaction as a mediating variable were found to have a statistically significant positive (+) effect on the dependent variable, quality of life. 본 연구는 대졸 초기경력자을 대상으로 직업가치가 직무만족의 매개를 거쳐 삶의 질에 미치는 영향력에 대해 실증분석을 통해 살펴보는데 데 목적이 있다. 이에 직업가치와 삶의 질의 관계에서 직무만족의 매개효과와 직업눈높이의 조절효과를 포함하는 매개된 조절효과를 확인하고자 하였다. 본 연구에서는 곰스데이터를 활용하여 직업가치 직무만족 그리고 직업눈높이를 측정하기 위한 문항을 살펴보았으며, SPSS 23.0과 SPSS Macro를 사용하여 자료 분석을 시행하였다. 매개된 조절모형은 매개 및 조절효과가 포함된 통합적인 모형이므로 매개효과와 조절효과, 그리고 매개된 조절효과를 차례로 검증하였다. 연구 결과는 첫째, 직무만족을 통한 매개효과 모형은 통계적으로 유의한 것으로 확인되었다. 다음으로 직업가치는 직접경로와 매개변수인 직무만족을 통한 간접경로로 삶의 만족도에 통계적으로 유의한 영향을 미치는 것으로 확인되었다. 셋째 직무만족을 통한 직업눈높이의 조절된 매개효과 모형은 통계적으로 유의한 것으로 확인되었다. 세부적으로 독립변수인 직업가치와 매개변수인 직무만족은 종속변수인 삶의 질에 통계적으로 유의한 정(+)적 영향을 주는 것으로 나타났다.

Aluminum nitride was synthesized using a carbothermal method from mesoporous alumina having a high surface area (> $1,000m^2/g$) as an aluminum source and CNTs (carbon nano tubes) as a carbon source. In this case the mesoporous alumina was used as the starting material instead of ${\alpha}-Al_2O_3$ with the expectation that the mesopores in mesoporous alumina act as channels for N2 gas and elimination of CO generated as by-product. It is also expected that the synthetic temperature should be lower compared to the use of ${\alpha}-Al_2O_3$ as a starting material due to its high surface area. The crystallinity of the produced aluminum nitride was studied by XRD and FT-IR, and the microstructure was investigated by FE-SEM. Also the purity of the aluminum nitride was analyzed through N/O determinator and ICP analysis.

The purpose of this study is to predict potential issues in elementary education due to the decline in school age population and establish a policy for elementary school education due to the decline in the aforementioned school age population. For this, the Delphi method was conducted twice, and Hershkowitz analysis and Borich needs analysis were also carried out. The results are as follows. Differentiated curricula: Provision of differentiated education according to students’ levels and needs was selected as the top priority, which was followed by subdivision of the roles of future teachers(learning coach, online teacher, one-to-one tutor, online learning manager, parent counselor, education software developer, etc.), the establishment of various schools: elementary and middle school connected education(e.g., integration as fundamental education schools), community connection schools to cover the issues of small schools, and a change in the administrative support system(a change in the number of administrative personnel and the general administrative system). Based on these results, it was found that there were several key issues due to the decline on school age population that needed to be preferentially developed out of sixteen finkings, and accordingly, this study suggested considerable implications from a perspective of educational policy. 본 연구의 목적은 학령 인구감소에 따른 초등교육을 위한 이슈를 발굴하고 이를 토대로 ‘학령 인구감소에 따른 초등 학교교육을 위한 정책 플레이’를 수립하고자 하는 것이다. 이를 위하여 2차에 걸쳐 델파이를 실시하고 허쉬코비치 분석과 Borich 요구분석을 한 결과는 다음과 같다. 최우선 순위로 차별화 교육과정: 학생 수준과 요구에 따른 차별적인 교육 제공이 선정되었고 이어 미래형 교사의 역할 세분화, 다양한 학교설립운영: 소규모 학교 이슈를 해결하기 위한 초중학교 연계 학교(예, 기초교육학교로 통합), 지역사회 연계학교 등과 이를 위한 행정지원체제 변화(행정인력의 정원 및 행정시스템의 변화) 등이 선정되었다. 이상의 연구 결과를 기반으로, 16개의 이슈 중 학령인구 감소에 따라 우선적으로 개발해야 하는 이슈가 분명히 존재하는 것으로 나타났으며 이에 따라 교육 정책 차원에서 고려할 수 있는 시사점을 제시하였다.

김은비,유정열,박선아,정운호,김종규 한국공업화학회 2019 한국공업화학회 연구논문 초록집 Vol.2019 No.0

This study is the synthesis and development of indium phosphide (InP) quantum dots (QDs) for fundamental device mechanism of Cd-free QLEDs. However, InP nanocrystals synthesized in organic solutions show low band-edge photoluminescence due to surface traps, dangling bonds, stacking faults. To improve the properties of the InP QDs, surface phosphorous atoms lying at the origins of trap sites were removed by nanocrystals were passivated with shell materials that have wider band gaps. we study that highly luminescent core-shell InP@ZnSe QDs have been fabricated via a injection method. Optical properties of the synthesized QDs were investigated with UV-vis, PL, QLED's device characteristics were also progressed. The average size of the QDs were shown to be 3.2nm by the TEM data. The first exciton of QDs is 620nm. The InP/ZnSe full width at half maximum is 40nm and the PLQY is 65%.

In this paper, we attach a raspberry pi and an object detection sensor to a cane to realize a multi-functional blind cane. We select three types of object detection sensors such as digital infrared motion sensor, ultrasonic sensor and IR obstacle detection sensor and select the most efficient sensor through the experiments for blind people to walk safely. Also, we use illuminance sensor for safe walking of the blind and experiment the LED brightness change according to illuminance value. Finally, we propose the cane for the blind and implement it and verify the usefulness of it by measuring the performance of the stick.

Expression of Ion Channels in Perivascular Stem Cells derived from Human Umbilical Cords

김은비,박원선,홍석호 한국발생생물학회 2017 발생과 생식 Vol.21 No.1

Potassium channels, the largest group of pore proteins, selectively regulate the flow of potassium (K+) ions across cell membranes. The activity and expression of K+ channels are critical for the maintenance of normal functions in vessels and neurons, and for the regulation of cell differentiation and maturation. However, their role and expression in stem cells have been poorly understood. In this study, we isolated perivascular stem cells (PVCs) from human umbilical cords and investigated the expression patterns of big-conductance Ca2+-activated K+ (BKCa) and voltage-dependent K+ (Kv) channels using the reverse transcription polymerase chain reaction. We also examined the effect of high glucose (HG, 25 mM) on expression levels of BKCa and Kv channels in PVCs. KCa1.1, KCaβ3, Kv1.3, Kv3.2, and Kv6.1 were detected in undifferentiated PVCs. In addition, HG treatment increased the amounts of BKCaβ3a, BKCaβ4, Kv1.3, Kv1.6, and Kv6.1 transcripts. These results suggested that ion channels may have important functions in the growth and differentiation of PVCs, which could be influenced by HG exposure.
