본 연구는 A사이버대학교에 근무하고 있는 수업조교의 활동을 통하여 온라인 수업 운영 모습을 드러내고, 특징을 도출하고자 한다. 이를 위해 수도권에 위치한 A사이버대학교에서 근무하고 있는 4명의 수업조교를 연구 참여자로 선정하여 참여관찰·심층면담·관련문서를 중심으로 질적 사례연구를 진행하였다. 연구결과 온라인 수업에서 수업조교의 활동은 크게 3가지로 구분된다. 업무 익히기에서는 ‘정신없는 학기초’, ‘업무 배우기’로 드러났다. 수업운영 보조로 ‘수업 모니터링’, ‘소통의 가교자’ 활동을 하는 것으로 나타났다. 좌충우돌하기에서는 ‘샌드위치 수업조교’, ‘갈등 해결하기’로 수업 운영 과정에서의 어려움과 해결 과정을 드러냈다. 이와 같은 수업조교 모습은 수업 보조자와 모호한 업무 적정선이라는 특징이 도출되었다. 이를 개선하기 위하여 수업조교 명칭 변화, 교수에게 역할 안내, 수업조교 업무 교육을 통하여 자연스럽게 조직문화가 개선될 수 있도록 해야 한다. 나아가 일반대학교에서의 온라인 교육에서도 학생 관리와 교수자의 온라인 교육 부담을 도와줄 인적·물적 자원과 교수자의 온라인 교육, 환경 구축이 필요하다. The purpose of this study is to reveal online class operations and derive characteristics through the activities of cyber university class assistants. To this end, four class assistants working at A Cyber U niversity located in the metropolitan area were selected as research participants and qualitative case studies were conducted focusing on participatory observations, in-depth interviews, and related documents. As a result of the study, the activities of class assistants in online classes are broadly divided into three categories. First, in the task mastery, it was revealed that ‘At the beginning of semesters with too much workload’ and ‘Work and learn at the same time’. Second, it was found that they were engaged in activities such as ‘Classroom monitoring’ and ‘Communication bridge’ to assist in class management. Lastly, in the left-to-right conflict, “Class assistant like a sandwich” and “Resolving Conflict” revealed difficulties and solutions in the course of operating the class. The characteristics of such class assistants were derived from the ambiguous line of work appropriate to the class assistants. In order to improve this, the organizational culture should be improved naturally by changing the name of the class assistants, guiding the instructors to the correct role of the class assistants, and job training for class assistants. Furthermore, in online education at general universities, it is necessary to provide human and material resources to help student the burden of online classes for instructors, to support online class operation education for instructors, and to establish an online education environment for universities.

The aim of the present study was to assess whether exposure to the combination of an extremely low frequency magnetic field (ELF-MF; 60 Hz, 1 mT or 2 mT) with a stress factor, such as ionizing radiation (IR) or H₂O₂, results in genomic instability in non-tumorigenic human lung epithelial L132 cells. To this end, the percentages of G2/M-arrested cells and aneuploid cells were examined. Exposure to 0.5 Gy IR or 0.05 mM H₂O₂ for 9 h resulted in the highest levels of aneuploidy; however, no cells were observed in the subG1 phase, which indicated the absence of apoptotic cell death. Exposure to an ELF-MF alone (1 mT or 2 mT) did not affect the percentages of G2/M-arrested cells, aneuploid cells, or the populations of cells in the subG1 phase. Moreover, when cells were exposed to a 1 mT or 2 mT ELF-MF in combination with IR (0.5 Gy) or H₂O₂ (0.05 mM), the ELF-MF did not further increase the percentages of G2/M-arrested cells or aneuploid cells. These results suggest that ELF-MFs alone do not induce either G2/M arrest or aneuploidy, even when administered in combination with different stressors.

The present study investigated the effect of perch material type (wood and steel) on performance, blood characteristics, and feather pecking. A total of 1,700, one-day-old female Hy-Line brown chicks were evenly assigned to two treatments (wood and steel). The body weight and uniformity of birds were investigated over a 10-week experimental period. Blood characteristics and feather pecking was conducted at week 10. The wood perch treatment (WP) and steel perch treatment (SP) did not differ in their body weight, uniformity, and serum biochemical profile (except inorganic phosphorus) of pullets. Inorganic phosphorus on serum in WP significantly higher than that in SP (P<0.05). Blood corpuscle composition (leukocyte, erythrocyte, and Heterophil / Lymphocyte ratio) of pullets did not show any significant differences among treatments at week 10. Serum corticosterone and feather score that is stress and welfare indices were not affected by the type of perch material. In conclusion, our results suggest that performance, blood characteristics, and feather pecking of pullets were not affected by the perch material type. The results of this study can serve as basic data for investigating the effects of perch type on layer pullets.

기혼남녀의 정서적 성숙이 혼외관계인식에 미치는 영향과 성적 자율성의 매개효과 - 성별 및 혼외관계 만연성의 조절효과분석을 중심으로

이희진 ( Lee¸ Hee Jin ) 부산대학교 여성연구소 2021 여성학연구 Vol.31 No.1

본 연구는 기혼 남녀(614명)의 정서적 성숙이 성적 자율성을 매개로 혼외관계인식에 미치는 효과와 이에 성별특성 및 혼외관계 만연성이 미치는 조절효과를 밝히고자 하였다. 연구결과는 다음과 같다. 첫째, 남성은 여성 보다 자신의 혼외관계에 대해 더 수용적이었다. 둘째, 남녀 모두 정서적으로 성숙할수록, 본인의 혼외관계에 대해서 수용적이지 않은 현상은 혼외관계만연성이 낮은 집단이나 높은 집단 모두 공통적으로 발견되었다. 기혼자들의 정서적인 성숙이 자신의 혼외관계에 대해 비판적인 인식을 갖게 하는데 기여한다는 사실이 입증되었다. 셋째, 정서적 성숙이 남성의 성적자율성에 미치는 긍정적 효과는 혼외관계 만연성이 낮은 집단에서만 유의하였고, 혼외관계 만연성이 높은 집단에서는 유의하지 않았다. 이와 같은 현상은 여성에서도 동일하게 나타났다. 넷째, 남성의 경우, 혼외관계 만연성이 낮은 집단이나 높은 집단 모두 성적자율성이 혼외관계 인식에 영향을 미치지 않았다. 그러나 여성의 경우에는, 성적 자율성이 높을수록 혼외관계에 대해서 수용적이지 않은 현상이 혼외관계 만연성이 높은 집단에서는 발견되었다. 다섯째, 혼외관계 만연성이 미치는 조절효과를 반영하지 않은, 성별 조절효과 분석결과에서는, 여성의 경우에서는 정서적 성숙이 혼외관계인식에 미치는 영향에 성적 자율성의 매개효과가 입증되었다. 그러나 이러한 성적 자율성의 매개효과는 혼외관계 만연성이 미치는 조절효과를 반영한 분석결과에서는 유의하지 않았다. 기혼남녀의 혼외관계인식에 성적 자율성이 미치는 효과는 성별 및 혼외관계 만연성에 의해 유의하게 조절된다는 사실이 입증되었다. 기혼남녀의 혼외관계인식에 정서적 성숙, 성적 자율성과 같은 개인의 심리특성이 미치는 영향에 대한 보다 정확한 이해를 얻기 위해서는 성별특성 뿐만 아니라, 기혼남녀가 생활하는 주변 환경의 혼외관계 만연성과 같은 환경적 요인이 이들의 혼외관계인식에 미치는 영향을 함께 중요하게 고려해야 한다. This study is conducted on married men(310) and women(304), to identify the effect of individuals' emotional maturity on their perception of extramarital relationship through their sexual autonomy, as well as the moderate effect of gender and the pervasiveness of extra-marital relationship. The notable findings are as follow: First, men are more receptive to their out-of-wedlock relationships than women. Second, the more emotionally mature both men and women are, the less receptive to their extramarital relationship is found in common in both the low and high prevalence group of that relationship. It has been proven that the emotional maturity of married people contributes to a critical perception of their extramarital relationships. The positive effect of emotional maturity on male sexual autonomy is significant only in the group with low prevalence of extramarital relationships, but not in the group with high prevalence of extramarital relationships. The same phenomenon is also found in women's groups. Forth, in the case of men, sexual autonomy did not affect the perception of extramarital relationships in either the low or high prevalence group. However, in the case of women, the higher the sexual autonomy, the less receptive the extramarital relationship, is found in groups with higher prevalence of extramarital relationships. Fifth, in the analysis results of gender control effects, which did not reflect the moderating effect of the prevalence of extramarital relations, in the case of women, the mediating effect of sexual autonomy on the effect of emotional maturity on the perception of extramarital relationships is proven. However, this mediating effect of sexual autonomy is not significant in the analysis results reflecting the moderating effect of the pervasiveness of extramarital relationships. It is proven that the effect of sexual autonomy on the perception of extramarital relationships between married men and women is significantly controlled by gender and the prevalence of extramarital relationships. In order to gain a more accurate understanding of the influence of individual psychological characteristics such as emotional maturity and sexual autonomy on married men and women's perception of extramarital relationships, it is concluded that the influence of not only gender characteristics, but also environmental factors such as the pervasiveness of extramarital relationships in the surrounding environment in which married men and women live, on their perception of extramarital relationships should be considered as important.

Capacity Loss Due to Polarization-Mismatch and Space-Correlation on MISO Channel

Heejin Joung,Han-Shin Jo,Cheol Mun,Jong-Gwan Yook IEEE 2014 IEEE TRANSACTIONS ON WIRELESS COMMUNICATIONS Vol.13 No.4

<P>This paper analyzes the effects of polarization-mismatch and space-correlation to a multiple-input and single-output (MISO) channel which is observable in the near future cellular communications environments such as large-scale antenna arrays and small cells. The analysis is based on a polarization-mismatched and space-correlated MISO channel which is modeled from the conventional dual-polarized channel. In the MISO channel, polarization-mismatch is described by the polarization-mismatch angle which is uniformly distributed from 0 to the maximum polarization-mismatch angle and space-correlation is described by the exponential correlation model. Assuming high SNR, approximate expressions of the ergodic capacity are derived as a function of the transmit power, number of transmit antennas, maximum polarization-mismatch angle, and space-correlation coefficient in four representative environments: narrowly or widely spread polarization-mismatch angles and slightly or highly correlated channels. Further, the capacity loss introduced by polarization-mismatch and space-correlation is derived with respect to the maximum polarization-mismatch angle and space-correlation coefficient. It is shown that the capacity loss introduced by polarization-mismatch is upper bounded by 2 bit/s/Hz. Whereas, the capacity loss introduced by space-correlation increase with the number of transmit antennas and is upper bounded by 0.832 bit/s/Hz. Required resources to compensate for the capacity loss is derived as well.</P>

Cerebrospinal fluid liquid biopsies for Mucopolysaccharidosis: absolute quantitation of glycans with high sensitivity using HILIC/MRM-MS

Heejin Jeong,Myung Jin Oh,Nari Seo,Hyun Joo An 한국당과학회 2022 한국당과학회 학술대회 Vol.2022 No.07

In recent years, liquid biopsy has been noted for its outstanding advantages over tissue biopsy including ease of sampling, effective monitoring, and longitudinal assessment of treatment dynamics. In particular, Cerebrospinal fluid(CSF), a body fluid that directly interacts with the extracellular fluid of the brain and central nervous system, is a representative body fluid used for liquid biopsy and is becoming a potential source for neurological study. Mucopolysaccharidosis is a fatal neurodegenerative lysosomal storage disease caused by lysosomal β-gal deficiency and of galactose-containing substrates accumulate in various tissues such as brain and liver. Therefore, continuous monitoring of changes in the expression of galactose substrates in the brain is important for the diagnosis and treatment of disease. However, the low protein content of the biofluid makes this difficult. Here, we developed a highly sensitive, absolute quantitation platform for N-glycans containing terminal galactose(A2G2/A2G2F) to determine mucopolysaccharidosis using liquid biopsy of mouse CSF within 2hours. N-glycans labeled with InstantPC were quantified using hydrophilic interaction chromatography(HILIC) coupled with multiple response monitoring(MRM)-MS. In particular, A2G2/A2G2F glycans are present in less than 5% even in very small amount of mouse CSF, but it is possible to quantify glycans in 300nL mouse CSF at the femtomole level. Indeed, we were able to achieve high reproducibility within 15% of CV in experimental/instrumental replicates in the concentration range of 0.1 to 500pg/μL with quantitative linearity. Our glycan quantification platform can be potentially applied for diagnosis and monitoring of patients for neurodegenerative diseases at trace amounts of CSF (about 5μL) in a much more convenient and non-invasive manner.

Comparison of Four Point-of-Care Devices for Pregnancy Test in Urine

Heejin So,Kyungsuk Kwon,Jungkyu Park,Kyeongmi Kim 대한임상검사정도관리협회 2023 Journal of Laboratory Medicine And Quality Assuran Vol.45 No.3

Point-of-care (POC) tests for human chorionic gonadotropin (hCG) are widely used in hospital laboratories. However, there is a lack of comparative studies focusing on pregnancy POC devices that test urine. In this study, we aimed to evaluate four commonly used pregnancy POC devices in Korea. From March to May 2023, remnant clinical urine samples were collected from 200 patients, consisting of 100 confirmed pregnant women and 100 nonpregnant women. The evaluated devices included the AllCheck hCG Card (Calth, Korea), Card ASAN Easy Test hCG (Asanpharm., Korea), Humasis hCG Card (Humasis, Korea), and careUS BEBE-CHECK (Wells bio, Korea). Among the four pregnancy POC devices, we observed a 99% negative percent agreement and 97% positive percent agreement. Only four samples showed discrepancies in results, which could be attributed to early pregnancy and abortion. Overall, the hCG POC devices assessed in this study demonstrated high concordance rates. However, we must be careful when interpreting urine pregnancy test results, particularly in cases involving early pregnancy or abortion.
