정명화 ( Myung-hwa Jung ),정성주 ( Sung-ju Jung ) 한국수산과학회 2021 한국수산과학회지 Vol.54 No.5

Microorganism-derived compounds, such as peptidoglycan, lipoteichoic acid, and β-glucan were supplemented in the scuticociliate Miamiensis avidus (M. avidus) vaccine to verify the specify component contribution to the adjuvant effect. Vaccine was formulated with the inactivated M. avidus antigen (YS2, 4.44×10⁵ cells/fish) in combination with either peptidoglycan (10 μg and 100 μg/fish), lipoteichoic acid (5 μg and 50 μg/fish), or β-glucan (10 μg and 100 μg/ fish). Olive flounder injected with peptidoglycan supplemented vaccine (10 μg and 100 μg/fish) exhibited significant protection, and the relative percent survival (RPS) was 55% and 65% at 4 weeks post vaccination (wpv), respectively, at the corresponding doses. The vaccine groups with added lipoteichoic acid (5 μg and 50 μg/fish) exhibited RPS of 40% and 5%, respectively. Additionally, the group with added β-glucan (100 μg/fish) exhibited RPS of 35%, but no effect was observed in the group with added 10 μg/fish β-glucan. At 8 wpv, olive flounder injected with peptidoglycan and lipoteichoic acid supplemented vaccines exhibited protection with RPS range of 11/11% and 5/21%, respectively, at the respective doses. M. avidus vaccine containing 10 μg and 100 μg/fish of β-glucan exhibited the RPS of 32% and 37%, respectively. Conclusively, peptidoglycan contributed in high protection of the M. avidus vaccine, and thus, it can be used as an effective adjuvant in the M. avidus vaccine.

정명화(Myung-Hwa Cheong),이성덕(Sung-Duk Lee),김익기(Ik-Ki Kim),송정은(Jung-Eun Song) 한국엔터테인먼트산업학회 2016 한국엔터테인먼트산업학회논문지 Vol.10 No.3

본 연구는 영화합작제작의 개념을 바탕으로 한중합작영화의 추진방향과 그 흐름에 대해서 알아보고 한중 합작영화의 결과에서 나타난 문제점과 개선방안 논의할 것이다. 문헌연구 외에도, 중국 내에 한중영화합작의 과정을 파악하기 위해, 중국에서 메인으로 사용하는 매개체에서 한중합작에 관련된 데이터를 수집하였다. 한중영화합작은 콘텐츠의 다양성과 인프라 구축을 위한 네트워크를 형성하며 한류의 발전에 토대가 된다. 하지만 여전히 한중합작영화는 흥행하는 경우가 드물어 지속적인 협력과 교류를 저해한다. 이를 해결하기 위해서는 상대방의 문화에 대한 꾸준한 연구와 효과적인 접근법이 필요하다. 향후 한국과 중국의 영화합작은 아시아를 대표할 문화적 콘텐츠를 공동으로 개발하여 세계 영화시장에서 경쟁력을 높여야 할 것이다. This study discusses the issues raised by the film co-production process between Korea and China and suggests ways to promote the co-production with understanding of its history and conditions between Korea and China. This study aims to find the ways to effectively cooperate between the two countries and to increase cultural exchanges based on cultural similarities and differences in order to also promote Hallyu. In addition to literature studies, the data is collected from the online resources and sites for films in China. The film co-productions between Korea and China build networks for setting infrastructure and for improving the quality and diversity of contents; furthermore, the co-productions will support the development of Hallyu. Still, the cultural differences between the two countries hinder the increase of co-productions and mutual understanding and cultural exchanges. To solve this issue, both countries need to keep studying the other’s culture and to find wise strategies to approach to the other. Both Korea and China should cultivate creativity together to produce film contents able to reflect Asian culture. By doing so, both countries can increase the competitiveness of Asian films in a global film market.

본 연구는 자기불일치가 안녕감에 미치는 영향에 있어 사회적 지지의 조절효과를 검증하는데 목적이 있다. 이를 위해 부산 및 경남에 소재한 전문대학에 재학중인 587명의 학생을 대상으로 자기불일치, 안녕감, 사회적 지지의 검사를 실시하였다. 자기불일치, 안녕감, 사회적 지지의 일반적인 특성을 알아보기 위해 SPSS 21.0을 활용하여 평균, 표준편차를 분석하고 변수 간의 관계를 확인하기 위하여 상관 분석을 실시하였다. 또 자기불일치가 안녕감에 미치는 영향에 있어서 사회적 지지의 조절효과를 살펴보기 위하여 위계적 중다회귀분석을 실시하였다. 연구결과 첫째, 자기불일치와 안녕감은 유의미한 부적 상관을 나타냈으며 사회적 지지와 안녕감은 유의미한 정적 상관을 나타냈다. 둘째, 연구 가설과는 달리 자기불일치와 안녕감의 관계에서 사회적 지지의 조절효과는 없는 것으로 확인되었다. 이러한 결과를 바탕으로 연구가 주는 시사점을 논의를 통해 밝혔으며, 연구의 제한점과 추후 연구를 위한 제언을 제시하였다. The aim of this study is to identify whether college students’ self-discrepancy has an effect on their well-being and to verify the moderating effect of social support on the relation between self-discrepancy and well-being. For this study, the preliminary research was conducted in the way that questionnaire tests on self-discrepancy, well-being, and social support were administered to 587 college students in Busan and Gyeongnam province. The test results were analyzed by means of SPSS 21.0 program. First, average and standard deviation were analyzed to examine the general characteristics of self-discrepancy, well-being and social support. Second, correlation analysis was used to examine the relationships between variables. Third, hierarchical multiple regression analysis was used to examine the moderating effect of social support on the relation between self-discrepancy and well-being. The conclusions drawn from the analysis are as follows. First, self-discrepancy had a significant negative correlation with well-being and social support had a significant positive correlation with well-being. Second, contrary to the research hypothesis, social support had no moderating effect on the relationship between self-discrepancy and well-being. Based on these findings, the implications and the limitations of the research findings were discussed, and recommendations for future research were provided.

Gastritis cystica superficialis (GCS) is an uncommon benign lesion which is characterized by hyperplastic foveolar epithelia and multi-cystically dilated glands, especially within the mucosa. It is usually observed in patients who had done stomach surgery before, but also infrequently found in an unoperated stomach. We report two cases of GCS, which occurred in patients who had never undergone stomach surgery. The first case was a 63 years old male with GCS accompanying with gastric adenoma, which was confirmed by endoscopic resection. The second case was a 55 years old female with GCS diagnosed by endoscopic resection, who had been misdiagnosed as raised erosive gastritis but did not respond to H2blocker treatment. Therefore, endoscopic resection is a safe and useful procedure to confirm the histological diagnosis of GCP.

분자선 증착법을 이용하여 MnTe 박막을 Si(100):B 및 Si(111) 기판 위에 성장시켰다. 두개의 K-cell을 사용하여 기판온도 $400^{\circ}C$ 및 Te가 풍부한 조건에서 MnTe 합성이 잘 이루어졌다. 이 경우 증착속도는 $1.1 {\AA}/s$이었고 성장된 층의 두께는 $700{\AA}$ 정도이었다. 합성된 MnTe 박막들에 대하여 X선회절, 초전도 양자 간섭계, Physical Property Measurement System, 홀효과 측정 등을 사용하여 그 구조적, 자기적, 전기적 특성들을 조사하였다. X선회절 측정 결과 Si(100) : B및 Si(111)기판 위에 성장된 MnTe는 다결정성의 hexagonal 구조를 나타내었으며, 자기적, 전기적 특성 측정 결과 분말형태의 MnTe와 비교하여 매우 다른 특성을 나타내었다. Zero-field-cooling(ZFC) 및 field-cooling(FC) 조건에서 취해진 자화율 측정에서 다결정 박막은 21 K, 49K, 210K 근처에서 자기적 전이 현상을 보였으며, ZFC와 FC 자화율 사이의 큰 불가역성이 나타났다. MnTe박막의 5K와 300K에서의 자기이력곡선은 강자성 상태를 나타내었으며 잔류자화값과 보자력은 5 K에서 $M_R= 3.5emu/cm^3$와 $H_c=55Oe$를, 300 K에서 $M_R= 2.1emu/cm^3$와 $H_c=44Oe$로 나타났다. 전기수송 특성 측정 결과, 온도에 따른 비저항은 저온에서 Mott variable range hopping 전도특성을 나타내는 전형적인 반도체 성질을 보여주었다. MnTe layers of high crystalline quality were successfully grown on Si(100) : B and Si(111) substrates by molecular beam epitaxy (MBE). Under tellurium-rich condition and the substrate temperature around $400^{\circ}C$, a layer thickness of $700{\AA}$ could be easily obtained with the growth rate of $1.1 {\AA}/s$. We investigated the structural, magnetic and transport properties of MnTe layers by using x-ray diffraction (XRD), superconducting quantum interference device (SQUID) magnetometry, and physical properties measurement system (PPMS). Characterization of MnTe layers on Si(100) : B and Si(111) substrates by XRD revealed a hexagonal structure of polycrystals with lattice parameters, ${\alpha}=4.143{\pm}0.001{\AA}\;and\;c=6.707{\pm}0.001{\AA}$. Investigation of magnetic and transport properties of MnTe films showed anomalies unlike antiferromagnetic powder MnTe. The temperature dependence of the magnetization data taken in zero-field-tooling (ZFC) and field-cooling (FC) conditions indicates three magnetic transitions at around 21, 49, and 210 K as well as the great irreversibility between ZFC and FC magnetization in the films. These anomalies are attributable to a magnetic-elastic coupling in the films. Magnetization measurements indicate ferromagnetic behaviour with hysteresis loops at 5 and 300 K for MnTe polycrystalline film. The coercivity ($H_c$) values at 5 and 300 K are 55 and 44 Oe, respectively. In electro-transport measurements, the temperature dependence of resistivity revealed a noticeable semiconducting behaviours and showed conduction via Mott variable range hopping at low temperatures.

Spin dynamics of magnetic tunnel junctions with free and fixed reference layers is investigated by ferromagnetic resonance micromagnetic simulations. First, in magnetic tunnel junctions with an exchange biased synthetic ferrimagnetic reference layer, a magnetization direction of each layer and the tunneling magnetoresistance are calculated for a DC magnetic field. To investigate the spin exciting modes in magnetic tunnel junctions, we simulate the ferromagnetic resonance frequency spectra with small RF magnetic fields. Exciting modes of the tunneling magnetoresistance calculated by an included angle between free and reference layers is interpreted from those of each layer. Spin exciting modes are different according to a signs of the DC magnetic field. In a negative magnetic field, FMR frequency spectra of free and reference layers are well elucidated by the modified Kittel’s equation. However, in a positive magnetic field, there is no simple analytic solution related to FMR frequency spectra due to the coupled modes. Since ferromagnetic layers in magnetic tunnel junctions are interactive each other, careful considerations of the reference and fixed layer as well as the free layer are required for understanding on the spin dynamics of magnetic tunnel junctions with an exchange biased synthetic ferrimagnetic reference layer.

Effects of doping rare earth elements on Ln site of $Ln_{0.7}Ca_{0.3}MnO_3$ (Ln = N d, Sm and La) were examined from structure, magnetic and electrical properties. Size of a-axis increased as following order of La < Nd < Sm, whereas c-axis was not much changed. Curie temperatures of 170 K for $Nd_{0.7}Ca_{0.3}MnO_3$, 110 K for $Sm_{0.7}Ca_{0.3}MnO_3$ and 250 K for $La_{0.7}Ca_{0.3}MnO_3$ were obtained. This result coincides with change of Mn-O bond length causing by a-axis lattice constant. The highest magnetroresistance ratios were 22% at 77 K for $Sm_{0.7}Ca_{0.3}MnO_3$, 32% at 110 K for $Nd_{0.7}Ca_{0.3}MnO_3$, and 33% at 180 K for $La_{0.7}Ca_{0.3}MnO_3$.
