The purpose of this study was to examine the differences in the psychological academic achievement motivation which drives powers and directions toward careers via making a career choice based on the knowledge of self-aptitude, having a support from his/her parents about the career choice, and having a will to overcome the career barriers against his/her parents. Data for this study were 286 high school students and Hotelling's T2 was used to test for significant differences. The results from the Hotelling's T2 indicated that there was a statistically significant difference between groups (students making versus students no making career choices based on the knowledge of self-aptitude) for mastery-approach goal orientation and learning flow. Similar pattern was also seen in students who have the support from their parents about the career choices. In addition, students who have the will to overcome the career barriers against their parents tend to have a higher mastery-approach goal and learning flow compared to students who have not. 본 연구는 청소년이 자신의 적성에 맞는 진로를 선택하는지, 부모님이 자녀의 진로선택을 지지하는지, 부모님이 진로선택을 반대하는 갈등상황에서 청소년이 갈등위기를 극복하려는 의지가 있는지에 따라 진로를 향해 나아가는 데 방향과 힘을 제공하는 중요한 심리적 학업성취 동기요인들이 어떻게 달라지는지 확인하고자 하였다. 연구결과, 적성과 진로선택이 일치하는 청소년은 숙달접근목표지향성이 높게 나타났고 학습몰입 정도도 높게 나타났다. 또한 부모님이 자녀의 진로선택을 지지하는 경우에는 숙달접근목표지향성과 수행접근목표지향성이 높게 나타났고 학습몰입도 높게 나타났다. 부모님과 진로선택이 불일치하더라도 자신의 진로선택을 유지 및 도전하고자 하는 청소년들도 숙달접근목표지향성과 학습몰입 정도가 높게 나타났다. 본 연구의 결과는 청소년의 진로선택 교육 및 상담 시 청소년의 적성에 기초한 진로선택 뿐만 아니라, 부모가 자녀의 적성을 이해하고 적성에 기초한 진로선택을 하도록 지지해줄 수 있도록 부모의 참여와 교육이 병행된 진로지도가 필요함을 시사하고 있다.

Evidence for Direct Inhibition of MHC-Restricted Antigen Processing by Dexamethasone

임선아,Turmunkh Gerelchuluun,이종길 대한면역학회 2014 Immune Network Vol.14 No.6

Dexamethasone (Dex) was shown to inhibit the differentiation,maturation, and antigen-presenting function ofdendritic cells (DC) when added during DC generation ormaturation stages. Here, we examined the direct effects ofDex on MHC-restricted antigen processing. Macrophageswere incubated with microencapsulated ovalbumin (OVA) inthe presence of different concentrations of Dex for 2 h, andthe efficacy of OVA peptide presentation was evaluated usingOVA-specific CD8 and CD4 T cells. Dex inhibited bothclass I- and class II-restricted presentation of OVA to T cells;this inhibitory effect on antigen presentation was much morepotent in immature macrophages than in mature macrophages. The presentation of the exogenously added OVApeptide SIINFEKL was not blocked by Dex. In addition,short-term treatment of macrophages with Dex had no discernibleeffects on the phagocytic activity, total expressionlevels of MHC molecules or co-stimulatory molecules. Theseresults demonstrate that Dex inhibits intracellular processingevents of phagocytosed antigens in macrophages

Previous studies have shown that Aloe QDM complex, which is consisted of chromium (Cr), aloesin (ALS) and processed Aloe vera gel (PAG), exert antidiabetic activity in a high fat diet-induced mouse model of type 2 diabetes. In this study we examined the mechanism of the antidiabetic activity of the Aloe QDM complex. Rat myoblast cell line L6 cells were cultured in the presence of Cr, ALS, and PAG alone and in combinations, and then the capability of the cells to uptake glucose was examined using radiolabeled glucose. All of the 3 agents, Cr, ALS and PAG, exerted glucose uptake-enhancing activity in L6 cells. The most potent capability to uptake glucose was observed when L6 cells were cultured with the Aloe QDM complex. The activity of the Aloe QDM complex to enhance glucose uptake was prominent in conditions where existing insulin concentrations are low. We also examined the effects of the Aloe QDM complex on the plasma membrane expression of GLUT4 in L6 cells. The Aloe QDM complex increased the content of GLUT4 in the plasma membrane, while decreasing the content of GLUT4 in the light microsome. Taken together, these results show that the antidiabetic activity of the Aloe QDM complex is at least in part due to the stimulation of glucose uptake into the muscle cells, and this activity of the Aloe QDM complex is mediated through the enhancement of the translocation of GLUT4 into the plasma membrane.

임선아,이종길,박찬수 한국생약학회 2016 생약학회지 Vol.47 No.2

Aloe vera L.(Aloe barbadensis Miller) has been used for many centuries for various medical, cosmetic and neutraceutical purposes. The gel of A. vera was reported to exert numerous biological activities including wound healing, immunomodulatory, anti-cancer, anti-inflammatory, anti-bacterial, anti-viral, anti-diabetic, and anti-psoriasis activities. Acemannan, found predominantly in the inner leaf gel of A. vera, has been identified as the main active ingredient exerting diverse biological activities. In this review, we summarized the recent findings on the immunomodulatory activities of acemannan. Studies that used purified acemannan demonstrate that acemannan exerts immune-stimulating, anti-cancer, anti-viral, and hematopoiesis-increasing activities. In addition, it is being clear that most of these activities of acemannan are mediated primarily by activating professional antigen presenting cells such as macrophages and dendritic cells.

Objectives: This study was conducted to analyze the factors related to unmet dental care needs in Korean adults who needed dental treatment. Methods: This study analyzed data from the 7th Korea National Health and Nutrition Examination Survey (2016-2018). Among the adults who participated in the National Health and Nutrition Examination Survey, 2,723 dental treatment who performed oral examinations were the final subjects. General characteristics and oral health characteristics were analyzed with complex sample chi-square test using the IBM SPSS program. Factors related to unmet dental care were analyzed by multiple logistic regression analysis. Results: As for unmet dental care needs related factors, bad oral health was 3.383 times higher, and usually was 1.736 times higher. In the use of dental clinic unmet dental care needs was 0.121 times lower. Unmet dental care needs was high, 1.366 times for those with the experience of tooth pain and 2.736 times for those with chewing difficulty. Conclusions: Based on the above results, it can be seen that oral health status or oral discomfort is related to unmet dental care needs. It is necessary to set goals to improve unmet dental care, recognize that one’s oral health condition is very important, and continuously educate about oral health for each life cycle.

The immunomodulatory activities of the ethanol extract of Gynostemma pentaphyllum, termed hereafter as GPE, were examined in immunosuppressed mice as well as in normal mice in the present study. Oral administration of GPE into mice prevented dexamethasone (DEX)-induced immunosuppression as determined by the mitogen-induced proliferation of the splenocytes and the the cytokine production (TNF-α, IL-1β) in the whole blood culture. In addition, oral administration of GPE increased antitumor host defense in mice implanted with sarcoma-180 tumor cells. The immunoaugmenting activity of orally administered GPE was also confirmed in mice immunized with ovalbumin (OVA). Mice that were orally administered with GPE generated much more potent OVA-specific cytotoxic T lymphocyte (CTL) responses upon intravenous OVA injection compared to the untreated controls. These results demonstrate that oral administration of the ethanol extract of Gynostemma pentaphyllum could be useful to increase host defense in immunocompromised situations such as stress- or tumor-induced immunosuppression.

축제 소셜 네트워크 서비스의 지각된 기술수용과 수용의도의 관계 연구 -확장된 기술수용모델을 중심으로-

임선아,김창수 한국관광학회 2017 관광학연구 Vol.41 No.6

To build relationships with others, people draw upon a range of communication methods, which vary constantly according to current trends. In recent times, social network services have been used as a primary means of communication to form relationships with others or to exchange information and knowledge. This has enabled users to actively choose and use diverse information, creating substantial social change and causing a variety of ripple effects. However, the use of social network services for festivals leaves much to be desired despite advancements in the new medium. This present study establishes the relationship between perceived technology acceptance factors when a social network service provides festival information and the subsequent acceptance intention. To achieve this objective, variables were theoretically considered, while the use of social network services as a new medium were analyzed based on the technology acceptance model suggested by Davis (1986). 최근 타인과의 관계형성이나 정보 및 지식을 교류하는 주요 커뮤니케이션 매체인 소셜 네트워크 서비스의 능동적인 이용형태는 다양한 정보를 선택할 수 있게 되면서 소셜 네트워크 서비스의 파급력은 다양한 분야에 사회적으로 큰 변화를 일으키고 있다. 그러나 아직까지 축제분야에서의 소셜 네트워크 서비스 활용은 미비한 실정으로, 소셜 네트워크 서비스에서 제공하는 축제정보를 경험한 이용객의 만족도를 측정하여 축제분야의 소셜 네트워크 서비스 활용방안을 모색하고자 한다. 소셜 네트워크 서비스라는 새로운 매체의 이용특성을 분석하기 위해 Davis(1986)의 기술수용모델을 수용하였으며, 기존 모델이 축제분야의 특성을 다양하게 대변할 수 없다는 문제점을 보완하기 위해 확장된 기술수용모델을 제시하였다. 실증분석을 위해 소셜 네트워크 서비스를 통해 축제정보를 검색한 경험이 있는 일반인을 대상으로 1월 22일부터 2월 13일까지 off-line 조사와 on-line 조사를 실시하여 총 382부의 유효 표본을 획득하였으며, 이 가운데 불성실한 응답 11부를 제외한 총 371부(97%)를 연구의 표본으로 사용하였다. 검증 결과 확장된 기술수용모델에서 소셜 네트워크 서비스의 특성을 반영하는 지각된 기술수용 요인은 축제 정보를 제공하는 소셜 네트워크 서비스의 지속사용의도와 축제행동의도에 유의한 영향 관계를 가지는 것으로 나타났으며, 소셜 네트워크 서비스를 이용하여 축제정보를 검색한 방문객들은 제공되는 정보의 신뢰도에 따라 지속적인 소셜 네트워크 서비스 이용의도와 함께 향후 검색한 축제를 직접 방문하거나 타인에게 추천하는 미래행동 의도가 형성됨을 시사하고 있다.

저소득층 아동의 인지와 사회-정서 발달이 읽기와 수학능력에 미치는 종단적 효과

임선아 한국아동권리학회 2012 아동과 권리 Vol.16 No.1

본 연구는 저소득층 아동들의 학교준비도가 시간이 경과함에 따라서 인지 및 사회-정서 발달과 이후 읽기와 수학성취에 어떠한 영향을 미치는지 규명하고자 구조방정식 모형을 통해 검증하였다. 종단연구 모형을 분석하기 위하여 본 연구는 유치원부터 초등학교 5학년까지의 미국 아동들의 종단적 자료(ECLS)를 사용하였으며 유치원, 3학년, 5학년의 세 시점에 모두 참여하고 빈곤수준 이하 수준의 생활환경에 살고 있는 1,730명의 아동들을 대상으로 하였다. 분석 결과, 인지적 준비도와 행동적 준비도가 읽기와 수학성취도 각각에 미치는 영향이 달라지며 자아-개념과 사회적 기술을 매개한 간접적 영향도 다르게 나타났다. 또한 사회적 기술과 자아-개념도 읽기와 수학성취에 다르게 영향을 미치는 것으로 나타났다. 본 연구의 결과는 학교준비도(인지적 준비도와 정서적 준비도)의 중요성을 타당화하고 이러한 학교준비도가 저소득층 아동들의 인지와 사회-정서 발달에 어떤 영향을 미치는지를 규명함으로써 장기적으로 저소득층 아동의 학교 적응과 성취를 증진하도록 돕기 위하여 학교 입학 전 학교준비를 시키는 개입 등에 대한 정보를 제공하는데 그 교육적 시사점이 있다. Previous research has shown that some low-income groups are at a disadvantage in terms of academic success when compared to high- income groups. Previous research has posited several explanations as to why the achievement gap still remains. The purpose of this study is to extend existing research on academic achievement by developing and testing a model of academic achievement (reading and math) in early elementary school students from low-income background. Using the Early Childhood Longitudinal Study-Kindergarten (ECLS-K), findings from this study revealed that the relationship between cognitive and social-emotional development operated differently for subject achievement. By identifying the cognitive and social-emotional development that may impede or facilitate student performance, educators could provide appropriate intervention for low-income students.
