K-pop은 1990년대 중국으로 유입된 후에 부침을 거듭하며 30년에 접어들었다. '한류' 현상을 일으킨 도화선으로서의 K-pop은 한국 대중문화를 대표하는 한 장의 명함이 되었고, '서양풍', '일본풍', '홍콩 대만 풍(港台 風)'에 이어 중국에서 열풍을 일으킨 하나의 대중문화로서 자리매김 하였다. 해외문화가 중국에 영향을 미친 영역이 넓고, 긴 시간 지속된 것은 지극히 드물어서 현대의 문화 간 커뮤니케이션의 전형적 사례라고 할 수 있다. 본 논문은 1988-2018년의 기간 동안 K-pop이 중국에 전파된 본말을 상세히 정리한 것을 이론적 기반으로, K-pop의 중국 내 전파 현황 전반에 대해 객관적인 평가를 하였다. 또한 설문조사를 통해 현재 K-pop 문화가 중국 대학생 집단에 미치는 영향을 살펴보고, 중국인들의 시각에서 발전 가능한 방안을 제시하였다. 이것으로 중국 내 K-pop의 문화 간 커뮤니케이션 연구에 이론적 기초와 시사점을 제공하려고 한다.

This study focused on the association of prostaglandins and a progestin, $17{\alpha}$, $20{\beta}P$-dihydroxy-4-pregnen-3-one ($17{\alpha}20{\beta}P$) during the ovulation process in longchin goby, Chasmichthys dolichognathus. We performed several in vitro experiments using $850-920{\mu}m$ diameter oocytes which were at the migratory nucleus stage. With the $890-920{\mu}m$ diameter oocytes, no significant difference in ovulation was observed in any of the prostaglandins (PGE1, PGE2, and $PGF2{\alpha}$) treated groups although PGE2 and $PGF2{\alpha}$ at concentrations of 50 ng/mL increased ovulation slightly compared with controls; however, $17{\alpha}20{\beta}P$ production was stimulated with PGE1 alone at low concentrations (5 ng/mL). In $850{\mu}m$ diameter oocytes, $PGF2{\alpha}$ at concentrations of 50 and 500 ng/mL resulted in a significant increase in ovulation. $17{\alpha}20{\beta}P$ (50 ng/mL) alone had no observable effect on ovulation, but in the combined of $PGF2{\alpha}$ 50 or 500 ng/mL it caused the greatest effect on ovulation. The sensitivity of oocytes to the induction of ovulation varies between 850 and $890-920{\mu}m$, it appeared to vary depending on the migration status of nucleus. These results suggest that $PGF2{\alpha}$ (or combined of $17{\alpha}20{\beta}P$) was more potent in inducing ovulation of the longchin goby.

The study was conducted to investigate the effects of alpha-linolenic acid (ALA) combined with bovine serum albumin (BSA) or methyl-beta-cyclodextrin (MBCD) on plasma and acrosomal membrane damages, mitochondrial activity, morphological abnormality, motility, and oxidative stress in frozen-thawed boar sperm. In previous our study, 3 ng/mL ALA had been shown protective effect during freezing process of boar sperm. Therefore, we used 3 ng/mL ALA in present study and ALA was combined with same molar ratio of BSA or MBCD (ALA+BSA and ALA+MBCD, respectively). To confirm the effect of two carrier proteins, same volume of BSA and MBCD without ALA were added during cryopreservation. Membrane damage, mitochondrial activity, reactive oxygen species (ROS) and lipid peroxidation (LPO) levels were measured using flow cytometry, and movement of sperm tail as motility parameter and morphological abnormality were observed under light microscope. In results, all of sperm parameters were enhanced by ALA combined with BSA or MBCD compared to control groups (p<0.05). Mitochondrial activity, morphological abnormality, ROS and LPO levels in ALA+BSA or MBCD groups were no significant difference compared with ALA, BSA and MBCD treatment groups. On the other hand, plasma and acrosomal membrane intact, and sperm motility in ALA+MBCD group were higher than single treatment groups (p<0.05), whereas ALA+BSA did not differ. Our findings indicate that carrier proteins such as BSA and MBCD could improve the effect of ALA during cryopreservation of boar sperm, and treatment of ALA with carrier proteins enhance membrane integrity, mitochondrial activity through reduction of ROS-induced LPO.

Soil acidification is one of major problems limiting crop growth and especially becoming increasingly serious in China owing to excessive use of nitrogen fertilizer. Only the STOP1 of Arabidopsis was identified clearly sensitive to proton rhizotoxicity and the molecular mechanism for proton toxicity tolerance of plants is still poorly understood. The main objective of this study was to investigate the transcriptomic change in plants under the low pH stress. The low pH as a single factor was employed to induce the response of the wheat seedling roots. Wheat cDNA microarray was used to identify differentially expressed genes (DEGs). A total of 1057 DEGs were identified, of which 761 genes were up-regulated and 296 were down-regulated. The greater percentage of up-regulated genes involved in developmental processes, immune system processes, multi-organism processes, positive regulation of biological processes and metabolic processes of the biological processes. The more proportion of down-regulation genes belong to the molecular function category including transporter activity, antioxidant activity and molecular transducer activity and to the extracellular region of the cellular components category. Moreover, most genes among 41 genes involved in ion binding, 17 WAKY transcription factor genes and 17 genes related to transport activity were up-regulated. KEGG analysis showed that the jasmonate signal transduction and flavonoid biosynthesis might play important roles in response to the low pH stress in wheat seedling roots. Based on the data, it is can be deduced that WRKY transcription factors might play a critical role in the transcriptional regulation, and the alkalifying of the rhizosphere might be the earliest response process to low pH stress in wheat seedling roots. These results provide a basis to reveal the molecular mechanism of proton toxicity tolerance in plants.

본 연구의 목표는 송대(宋代)와 민국(民國) 이후의 청동기 화문(花紋)의 내용과 성과를 대상으로 이들 두 시대의 학술적 성취를 비교하여 고찰해 보는 것이다. 이러한 과정을 거쳐 중국의 청동기 연구 역사에서 청동기 화문(花紋) 연구의 기원과 발전 과정을 비교하여 살펴보고 이들의 학술적 가치를 알아보았다. 청동기를 연구하는 것은 종합적 성격의 학문이다. 그러나 과거에는 청동기 위에 새겨진 명문(銘文)이나 청동기를 분류하는 것을 위주로 연구되었다. 하지만 이에 비해 청동기 화문(花紋)에 대해서는 연구가 상대적으로 소홀히 진행되었다. 청동기 화문(花紋)은 고고학(考古學)과 신화학(神話學) 등의 학문과 연관되어 있으며 고대인들의 상상력을 알아볼 수 있는 중요한 단서를 제공하고 있다. 중국에서 본격적인 청동기 연구는 송대(宋代)로부터 시작되었다. 그 이후 청대(淸代)에는 청동기에 대한 연구가 다시 부흥했지만 청동기 화문(花紋)에 대해서는 특별한 학술적 성과가 없었다. 하지만 민국(民國) 시기에 이르러 청동기 화문(花紋) 연구는 송대(宋代)의 뒤를 이어서 수준 높은 발전을 이루게 되었다.

The purpose of this study is to provide information to understand the context of the Antarctic Treaty System by looking back on its development process. It also aims to review the roles and activities of the CEP in the System in order to support the improvement of our Antarctic science policy. This study considered the developmental histories of independent conventions for Antarctic conservation and Protocol on Environmental Protection to the Antarctic Treaty under the system. CEP, established in accordance with the Protocol, has expanded its roles in the ATCM under the circumstances of climate change and increasing human activities in the treaty area. I examined CEP's functions, relationships with formal observers, and its activities along with CCRWP. In addition, I have estimated the contribution of the Parties to the CEP based on the documents submitted by the Parties. The leading Parties of the System have strengthened their initiatives to expand contributions to CEP with their output based on national Antarctic Program. However, Korea has not been able to take initiatives in the System even though Korea has invested considerable resources in its Antarctic program. To strengthen Korea's capability to instigate initiatives in the system, I suggest the following approaches: Firstly, Korea should improve its Antarctic science policy based on the newly established CEP five-year work plan; Secondly, Korea should organize a long-standing expert group to focus on Antarctic environmental policy and related scientific information; finally, Korea should intensify its collaboration with other Parties in developing Antarctic environmental priority issues.

The aim of present study was to investigate regulatory mechanism of alpha-linolenic acid (ALA) during in vitro maturation (IVM) on nuclear and cytoplasmic maturation of porcine oocytes. Basically, immature cumulus-oocyte complexes (COCs) were incubated for 22 h in IVM-I to which hormone was added, and then further incubated for 22 h in IVM-II without hormone. As a result, relative cumulus expansion was increased at 22 h after IVM and it was enhanced by treatment of ALA compared with control group (p < 0.05). During IVM process within 22 h, cAMP level in oocytes was decreased at 6 h (p < 0.05) and it was recovered at 12 h in ALA-treated group, while oocytes in control group recovered cAMP level at 22 h. In cumulus cells, it was reduced in all time point (p < 0.05) and ALA did not affect. Treatment of ALA enhanced metaphase-I (MI) and MII population of oocytes compared with oocytes in control group at 22 and 44 h, respectively (p < 0.05). Intracellular GSH levels in ALA group was increased at 22 and 44 h after IVM (p < 0.05), whereas it was increased in control group at 44 h after IVM (p < 0.05). In particular, the GSH in ALA-treated oocytes during 22 h of IVM was higher than control group at 22 h (p < 0.05). Lipid amount in oocytes from ALA group was higher than control group (p < 0.05). Treatment of ALA did not influence to absorption of glucose from medium. Cleavage and blastocyst formation of ALA-treated oocytes were enhanced compared with control group (p < 0.05). These findings suggest that supplementation of ALA could improve oocyte maturation and development competence through increasing GSH synthesis, lipid storage, and regulation of cAMP accumulation during early 22 h of IVM, and these might be mediated by cumulus expansion.

Background: Phenological studies are a prerequisite for accomplishing higher productivity and better crop quality in cultivated plants. However, there are no phenological studies on Panax ginseng that improve its production yield. This study aims to redefine the phenological growth stages of P. ginseng based on the existing Biologische Bundesanstalt, Bundessortenamt und Chemische Industrie (BBCH) scale and proposes a disease control reference. Methods: This study was conducted at the Korea Ginseng Corporation Experiment Station in Gyeonggi province, South Korea. Phenological observations were performed once weekly or twice monthly, based on the developmental stages. The existing BBCH scale with a three-digit code was used to redefine and update P. ginseng's phenological growth codes. Results: The phenological description is divided into eight principal growth stages: three for vegetative growth (perennating bud, aerial shoot, and root development), four for reproductive growth (reproductive organ development, flowering, fruit development, and fruit maturation), and one for senescence according to the extended BBCH scale. A total of 58 secondary growth stages were described within the eight principal growth stages. Under each secondary growth stage, four mesostages are also taken into account, which contains the distinct patterns of the phenological characteristics in ginseng varieties and the process of transplanting seedlings. A practical management program for disease control was also proposed by using the BBCH code and the phenological data proposed in this work. Conclusion: The study introduces an extended BBCH scale for the phenological research of P. ginseng.

오래 전부터 기독교 신앙공동체는 교회의 윤리적 규범과 행동양식을 성찰 대상으로 삼은 채 어떤 형태의 도덕 판단이 적절하고, 올바른 기독교적 행동양식이 무엇인지 규명하려고 노력해왔다. 기독교교육 역시 피아제와 콜벅의 심리적 합리주의에서 근거를 찾으려고 했으나 이성 중심의 구조발달주의는 해답을 제시하지 못했다. 실제로 도덕 판단 과정에서 정서를 배제한 채 인지 또는 이성을 과도하게 강조하는 한편, 무엇보다 자율성을 중시했던 구조발달주의는 기대했던 것과 달리 도덕적 상대주의를 초래하고 말았다. 뿐만 아니라 인간의 도덕 추론과 행위 사이의 간극을 적절하게 해명하지 못했을 뿐더러 도덕성을 사회문화적 맥락에서 과도하게 해석하려고 했다는 비판을 받았다. 이런 구조발달주의의 한계는 도덕 판단 능력이 뇌에 물리적으로 배선되어 있고, 피질과 번연계 간의 네트워크를 상당 부분 의지하고 있다고 주장하는 신경윤리, 특히 도덕 심리 이론에 의해 최근에 재해석되고 있다. 이 논문은 새롭게 등장한 신경윤리의 연구주제 가운데 일부를 검토하고 나서 도덕성을 신경과학적으로 설명하는 주요 이론을 중심으로 기독교교육학이 향후 고려해야 할 시사점을 거론하는 것을 목적으로 삼고 있다.
