In vitro culture (IVC) can be used for a variety of assisted reproductive technologies. However, IVC in dog has been low efficient compared to other mammalian. It is believed that an embryo developmental block in IVC embryos is cause of low production efficiency. There is no study of embryo developmental block in dog yet. In this study, we attempted to estimate the beneficial role of EDTA in canine parthenogenic (PA) embryos development to overcome embryo developmental block. The PA embryos were divided into EDTA treated and non-treated groups. Embryo developmental efficiency was measured by activating chemically parthenote. After EDTA induction, PA embryos were evaluated for embryonic development, ROS activity, mitochondrial integrity, ATP production and genomic activation. The EDTA treated PA embryos showed significantly higher survival rate and improved cavity formation compared to non-treated. Moreover, cytoplasmic ROS level was mitigated and mitochondrial membrane potential was found significantly higher in EDTA treated group followed by higher ATP production. Furthermore, major embryonic genomic activation specific markers/factors were also elevated in EDTA treated group. Conclusively, these results indicated that EDTA showed substantially positive effect to overcome embryo developmental block in canine.

Generally, in vivo, primary oocytes are grown and matured into secondary oocytes in the ovarian follicles. Quality of the oocytes matured in vivo is higher than that of oocytes matured in vitro, indicating the importance of materializing the microenvironment of ovarian follicles for production of high quality oocyte. Therefore, we tried to mimic the stiffness of ovarian follicles using an agarose as a biocompatible natural polymer. Unfortunately, to date, there are no many reports on whether the quality of porcine oocytes can be increased effectively under the soft matrix. Accordingly, we tried to evaluate the effects of IVM using different mechanical properties of agarose substrate on developmental competence of porcine oocytes. Agarose substrate was constructed and cumulus-oocyte-complexes (COCs) retrieved from porcine medium antral follicles were matured on non-coated (control) culture dish or dishes coated with 1% and 2% (w/v) agarose substrate. Then, cumulus expansion, embryonic development after parthenogenetic activation, and gene expression level were analyzed and compared. As the results, significant increase in blastocyst formation and cumulus expansion were detected in COCs matured on 1% (w/v) agarose substrate compared with control. Moreover, oocytes of COCs matured on 1% (w/v) agarose substrate showed significantly higher BMP15 expression level compared with control. Pro-apoptotic gene BAX expression was significantly increased in oocytes of COCs matured on 2% (w/v) agarose substrate compared with control. In the glycolytic enzyme phosphofructokinase (PFKP) gene expression, cumulus cells of COCs matured on agarose substrate showed significantly higher PFKP expression than control while they showed significantly lower BAX expression than control. These results demonstrated that quality of porcine oocytes could be increased efficiently by the IVM of immature oocytes on the soft culture matrix using agarose.

This study was conducted to evaluate the effects of insulin and epidermal growth factor (EGF) in a in vitro growth (IVG) medium on oocyte growth, in vitro maturation (IVM) and embryonic development of pig oocytes derived from small antral follicles (SAF) less than 3 mm in diameter. SAF oocytes were cultured for 2 days to induce IVG in alpha-minimal essential medium supplemented with 1 mM dbcAMP and 15% (v/v) fetal bovine serum. After IVG culture, oocyte maturation was induced by culturing IVG oocytes in IVM medium for 44 h. IVM oocytes that extruded the first polar body were selected and induced for parthenogenesis (PA) by applying electric stimulus. SAF oocytes cultured under the insulin treatment showed a significantly increased (P < 0.05) nuclear maturation (73.8%) compared to those cultured with insulin and EGF (59.8%). After PA, the proportions of blastocysts based on the number of metaphase II oocytes were significantly higher (P < 0.05) in oocytes that were cultured for IVG with insulin, EGF, and insulin + EGF (32.4%, 35.2%, and 34.8%, respectively) than in control (22.9%). IVG oocytes treated with insulin showed an increased oocyte diameter (116.3 μm) compared to those treated with insulin and EGF (114.0 μm) (P < 0.05). Intra-oocyte GSH content significantly increased (1.07 pixels/oocyte) by insulin treatment during IVG compared to that of oocytes treated with insulin + EGF (0.78 pixels/oocyte). These results demonstrate that IVG culture of SAF oocytes under insulin or/and EGF treatment supports oocyte maturation and improves embryonic development to the blastocyst stage after PA in pigs.

Mammalian fetal ovaries contains numerous primordial germ cells, however fewer ones can yield mature oocytes due to apoptosis and follicle atresia. Successful in vitro reconstitution of primordial germ cells has recently had a significant effect in the field of assisted reproductive technologies. However, the regulatory mechanisms underlying oogenesis remain unknown and recapitulation of oogenesis in vitro remains unachieved. Therefore, development of methods for obtaining mature oocytes by culturing the fetal ovaries in vitro could contribute to clarify these mechanisms. We adapt an in vitro system for culturing mouse fetal ovaries that support successful follicle assembly and improve oocyte growth and maturation. Ovarian tissues from 12.5 days postcoitum (dpc) fetal mice were cultured in vitro and the matured oocytes were differentiated from primordial germ cells after a 31 days culture period. Our results demonstrate that mouse fetal germ cells are able to form primordial follicles with artificial ovarian cells, and that oocytes within the growing follicles are able to mature normally in vitro. Taken together, this in vitro culture system is expected to aid in the development of new strategies to identify the reasons behind failure of follicle assembly and offer a platform for innovative research into preservation of female germ cells and conservation of endangered species.

Poor embryo quality and low blastocyst formation have been major limitations in establishment of cloned embryonic stem cells and production of cloned animals through somatic cell nuclear transfer (SCNT). Aggregation of embryos is a promising method for improving developmental competence of blastocysts. The aim of this study was to improve the blastocyst formation and the quality of parthenogenetic (PA) pig embryos by the aggregation of blastomeres at the 4-cell stage that were cultured in various type of culture dishes with or without phytohemagglutinin (PHA). The PA embryos were produced by the general method of our laboratory. On Day 2 after PA, the zona pellucida of 4 cell-stage embryos were removed by treatment with 0.5% (wt/vol) pronase solution. The 3x zona-free blastomere (ZFB) were randomly distributed in each of the following treatments for aggregation. ZFB were cultured for 5 days at 39℃ in an atmosphere 5% CO2, 5% O2, and 90% N2. In Experiment 1, effect of culture dishes on the aggregation efficiency and developmental competence of PA embryos were investigated. ZFB were cultured on non-coated (control) culture dish or dishes coated with 1% (wt/vol) agarose substrate (AS) or Well of the Well in dishes coated with 1% (wt/vol) agarose substrate (WAS). The ZFB cultured in WAS showed significantly higher (P<0.05) aggregation (81.2%) than AS and control (21.6-45.5%). The mean cell number in blastocysts derived from AS and WAS (81.4-89.3 cells/blastocyst) was significantly higher (P<0.05) than that of control (63.8 cells/blastocyst). In Experiment 2, effects of 150 ug/ml PHA treatment on the aggregation efficiency and developmental competence of embryos were investigated. The ZFB cultured in AS with PHA showed a higher (P<0.05) aggregation rate (90.0%) than that in AS without PHA, control with PHA, and control (39.2%, 57.9% and 17.5%, respectively). In conclusion, aggregation of porcine ZFB treated with PHA and agarose substrate could be a useful technique for producing improving blastocyst development with increased mean cell number of blastocysts in pigs.

북한 서포항 유적은 구석기시대부터 청동기시대까지 형성되어, 동북한 선사시대 문화의 흐름을 살펴볼 수 있다는 점에서 중요하다. 그러나 유적의 절대연대가 측정되지 못해서 북한학계에서도 중국과 비교연구 하면서 연대를 소급시킬 뿐이었다. 그런데 이 유적에서는 신석기문화층 뿐만 아니라 청동기시대문화층도 연해주문화와의 관련성이 토기 및 토우 등에서 뚜렷하게 관찰된다. 이미 서포항 청동기시대는 연해주 청동기문화와 관련지어져 왔으나 시니가이 문화의 서부1유형이 새롭게 고찰되고, 리도프카문화의 토기가 관찰됨에 따라서 서포항유적의 청동기시대층의 편년을 정리하고자 한다. 그 결과 서포항 청동기시대 4계의 단계로 구분되는데, 서포항 청동기 1단계는 유적의 5기가 해당된다. 7호 주거지에서 출토된 시니가이 문화 서부 1유형의 파수가 한쪽만 달린 토기가 출토되는 등 토기와 석기가 모두 시니가이 문화 서부 1유형과 비슷하다. 서포항 청동기 2단계는 5호, 6기 퇴적층 일부 토기가 포함되며, 시니가이 문화의 서부 1유형과 동부 2유형이 공존하는 특징이 확인된다. 서포항 청동기 3단계는 2호 주거지와 이와 유사한 유물이 확인되는 7기 퇴적층 일부를 포함한다. 시니가이 문화의 서부 2유형과 동부 2유형이 함께 확인되는 단계이다. 서포항 청동기 4단계는 7기에서 확인되는데, 4호와 10호 주거지 및 7기 퇴적층 유물과 6기 퇴적층유물도 일부 포함되며, 주로 리도프카 문화와 관련성이 있다. 이를 바탕으로 시니가이 문화 및 리도프카 문화와 절대연대를 비교하면 1단계는 3300~3200년 전, 2단계는 3200~2900년 전, 3단계는 2900~2500년 전, 4단계는 2500~2300년 전으로 볼 수 있다. 서포항 5기보다 이른 시기의 동북한 청동기시대 유적은 범의구석 1호인데, 이곳에서 출토된 대부마연 토기가 마르가리토프카 문화의 돌대각목 혹은 이중구연의 적색마연토기로 자연스럽게 이어진다. 따라서 동북한에서 청동기시대는 신석기시대부터 단절 없이 이어지며, 자연스럽게 변화되며, 특히 서포항 유적의 5~7기에서는 연해주의 청동기시대문화인 시니가이문화, 리도프카문화 특징이 반영되었다.

Destruxins (Dtxs) are insecticidal cyclic hexadepsipeptides produced by the entomopathogenic fungus Metarhizium anisopliae. Media composition for dtxs production was optimized with industrial grade media. Glycerol and casein peptone were selected as a carbon source and a nitrogen source, respectively. Dtxs production varied with C/N ratios. High yields of dtxs were observed at C/N ratios ranging 0.3 to 1.5, with concentrations mostly higher than 800 mg/L. Low yields were caused by high C/N ratio ranging from 3.0 to 8.0, resulting in less than 500 mg/L. The highest yield of Dtxs was obtained with 2% glycerol and 3% casein peptone, showing 192.2 mg/L of dtx A, 911.1 mg/L of dtx B, and 113.3 mg/L of dtx E, respectively. These results indicated that dtxs production is highly influenced by C/N ratio, especially the content of nitrogen source.

Somatic cell nuclear transfer (SCNT) is a useful biotechnological tool for animal cloning. Until now, SCNT has been inefficient, especially in dog. It is believed that an embryo developmental block in SCNT embryos is cause of low production efficiency. However, no studies have been performed on canines for embryo developmental block. In this study, we attempted to evaluate the beneficial role of EDTA in canine parthenogenic (PA) embryos development to overcome embryo developmental block. The PA embryos were divided into 0.01 mM EDTA treated and non-treated groups. Embryo developmental efficiency was measured by activating chemically parthenote. After EDTA induction, PA embryos were evaluated for embryonic development, Reactive Oxygen Species (ROS) activity, mitochondrial integrity, ATP production and genomic activation. The EDTA treated PA embryos showed significantly higher survival rate and improved cavity formation compared to non-treated. Furthermore, cytoplasmic ROS level was mitigated and mitochondrial membrane potential was found significantly higher in EDTA treated group followed by higher ATP production. Moreover, major embryonic genomic activation specific markers/factors were also elevated in EDTA treated group. Conclusively, we elucidated that EDTA showed substantially positive effect to overcome embryo developmental block in canine.

지난 수십 년간 많은 기업들은 인수 합병을 실시했다. 기업들은 인수 합병을 통해 서로의 실적을 개선 할 수 있을 것으로 예상했다. 하지만, 실제로는 그 반대의 결과를 가져왔다. 많은 사람들이 이 실패의 원인을 분석하여 찾은 실패의 주된 원인은 합병후 조직문화의 통합에 실패했기 때문이였다. 따라서, 본 논문의 주요 목표는 합병 후 조직 문화의 통합에 성공하기 위한 구체적인 요인을 찾는 것이다. 이 논문이 찾은 구체적인 요인은 5개의 중요한 요소는 직원 유지와 관련된 3가지 요소와 조직문화와 관련된 2가지 요소 였다. 직원 유지와 관련된 3가지 중요 요소는 직접적인 의사소통, 보상과 혜택에 대한 동기 부여, 그리고 강력한 경영 리더십 통해 성과가 향상 되며, 조직문화 관리와 관련된 중요 요소는 효과적인 오픈 커뮤니케이션 과 문화 통합 프로그램 통해 양쪽에 직원들이 서로 문화를 이해하도록 돕는 것이다. 이 요소에 촞점을 맞춘결과 르로 삼성는 인수 합병 이후 높은 실적 증가율을 보였다. 끝으로 이 연구를 위해 사용한 자료는 2002년에 수집되었지만 르노 삼성 자동차로부터 독점적으로 받은 실질적 자료로써 그 가치와 의미가 있다 하겠다.

The purpose of this study is to derive landscape image characteristics of “Insadong-gil” using text mining analysis of big data. Keywords were collected and analyzed through blogs and cafes containing “Insadong-gil” on domestic portal sites Naver and Daum as basic data for research purposes. As a result, 28 landscape image characteristic keywords related to “Insadong-gil” were derived, and the correlation of the extracted keywords was examined to analyze landscape image characteristics. The results of the landscape image characteristics of Insadong-gil are as follows: First, Insadong-gil is recognized as a street of diverse cultures, including “traditional culture” and a “clean street” reputation. Second, we see that “couples” and “tourists” visit for activities such as a “picnic”, “date”, or “travel”. Couples are able to take “photos” and foreign tourists visit to enjoy the hanbok experience on Insadong-gil. Third, the purpose of visiting Insadong-gil includes keywords for activities such as “picnic”, and “walking”, but cultural activities such as exhibitions, performances, and experiences appeared less. Therefore, it is deemed necessary to continuously plan and implement marketplaces, festivals, and events on Insadong-gil as supplements; and create a cultural space visitors can actively approach with familiarity.

수사학은 훌륭한 말에 관한 재주이거나 학문이다. 어느 경우에나 수사학을 활용하는 목적은 말과 행동 등으로 남을 이해시키고 설득시키기 위한 것인데 연설뿐만 아니라 연극과 같은 각종 매체에서도 자주 쓰인다. 본고가 수사학적 각도로 탐구하려는 중국가수 薛之谦(설지겸)의 노래 <演员>(연기자)은 출시된 지 몇 년이 흘렀지만 아직도 많은 중국인들과 외국인들의 뇌리 속에 남아있는데 과연 어떤 요인들로 인하여 청자들과 깊은 공감대를 형성했는지에 대해 착상, 배열, 표현, 발표 등 서양 수사학 방법론을 적용하여 분석한다. 국내에서 중국 가수의 노래에 대해 수사학적으로 분석한 논문은 현재 전무한데 새로운 분석틀을 적용하여 현대중국 대중문화의 트렌드에 대한 체계적인 탐구를 시도하였다.

This study will introduce the foods recorded in Gyemiseo and disclose the substantive characteristics of traditional Korean food in the early stage of the Joseon Dynasty. Gyemiseo is a cook book manuscript written in the Chinese language that was rebound into book format at the end of the Joseon Dynasty in 1911, some 358 years after it was originally written in the 163rd year of the Joseon Dynasty (1554) While the majority of cook books begin with recipes for various types of wines and liquor followed by those for fermented sauces, fermented vegetables (such as kimchi), vinegars and storage methods, etc., Gyemiseo begins with recipes for fermented sauces, followed by recipes for various kimchis, how to make vinegars, main meals, side dishes, rice cakes and confectionaries, with recipes for wines and liquor introduced last. Therefore, it can be assumed that the methods of brewing wines and liquors were additionally recorded for bookbinding. There are a total of 128 recipes recorded in Gyemiseo, including 13 for fermented sauces, 14 for kimchi, 11 for the main meal, 26 for side dishes, three storage methods, four for rice cakes and confectionaries, and 44 for wines and liquors. It is believed that contents of Gyemiseo will provide a foundation on which to pursue researches on the process of transition of cooking methods of traditional cuisines of Korea during the Joseon Dynasty.

일본은 급속한 저출산고령화의 진전에 따라 사회보장의 관점에서 고령자 복지지출에 재정적 부담이 가중되고 있다. 앞으로 “인생 100년 시대” 라는 초고령사회와 장수사회가 본격화하기 때문에 사회보장정책과 고령자 복지정책의 방향은 의료 개호 관계 비용의 절감이 중요한 열쇠가 되고 있다. 고령자 복지정책으로 지금까지 “양로원” 으로 총칭되는 각종 요양시설과 고령자 전용주택의 건설이 정책적으로 진행되어 왔다. 그러나 복지사상이 각 세대를 중심으로 한 가족주도로 고령자을 지원하 는 “가족개호형”에서 사회가 공동으로 지원하는 “사회개호형”으로 전통적 복지사상이 변화되고 있다. 다시 말하면 복지사상이 기존의 “가족(개인)의 책임”이라는 전통적인 사고방식에서 “사회의 책임”이라는 현실적 인 사고방식(사회보장의 강화)으로 변화하고 있는 것이다. 이 복지사상의 변화의 배경에는 일본이 경제적으로 부강해지고 근대화 · 핵가족화 · 고령화가 더욱 진행되면서 가족단위의 2세대 또는 3세대의 생활(공동으 로 생활하고 공동으로 고령자 지원)이 현실적으로 어려워지고, 가족구성원의 경제활동이나 사회활동에 의해 필연적으로 가족단위가 분해되었다는 현실이 있다. 또한 사회보장의 수비범위가 유럽의 사회보장의 기본적 사상에 자극되어 국민이 소극적인 사회보장에서 적극적인 사회보장으로의 정책적 전환을 요구하는 현실도 있다. 앞으로의 사회보장정책의 기본방향은 고령자의 생활을 지원하는 주체를 “가족”에서 “사회”로 발상 (복지사상)의 전환은 불가피한 상황이다.

본 연구에서는 딸기의 생육 및 환경관련 데이터를 활용하여 딸기 재배 온실의 최적 환경 구현을 위한 시스템을 선정하고 생산성 향상에 대한 연구를 위한 기초 자료로 활용할 목적으로 서부 경남 지역 중 딸기 재배로 유명한 지역의 온실을 대상으로 현장조사를 실시하였다. 이 결과를 바탕으로 경상대학교 내에 딸기 재배용 테스트 베드 온실을 설치하여 연구를 실시하고자 본 연구를 수행하였다. 그 결과 재배농가의 연령대를 보면, 상대적으로 50대 및 60대가 가장 많았지만, 50대 이하가 27개 농가로서 전체의 약 67.5%정도이었고, 60대 이상은 32.5%정도인 것으로 나타났다. 재배경력의 경우, 10년 이하가 주류를 이루고 있지만 30년 이상인 경우도 있었다. 대상농가 모두가 단동온실로서 대부분이 아치 형태인 것으로 나타났으며, 양액재배 농가가 약 75%정도로 토경재배보다 많은 것으로 나타났다. 양액재배의 경우, 전체 농가가 고설재배를 하고 있었다. 단동온실의 폭, 측고 및 동고는 조사지역에 관계없이 각각 7.5~8.5m, 1.3~1.8m 및 2.5~3.5m정도 이었다. 서까래 간격도 0.7~0.8m정도인 것으로 나타났다. 고설재배의 경우, 고설재배 베드의 폭, 높이 및 간격은 각각 0.25m전후, 1.2m전후 및 1.0m전후인 것으로 조사되었다. 딸기 품종의 경우, 국산이 약 97.5%를 차지하고 있었고, 이 중 설향이 약 65.0%로서 가장 선호하고 있는 것으로 나타났다. 온실 내부 환경 요인으로 38개 농가가 온도와 상대습도만 계측하였다. 2개 농가는 최근에 국산 제품인 스마트 팜 시스템을 도입한 농가도 있었다. 양액재배의 경우는 양액제어 시스템을 이용하고 있었다. 이 외에도 관비기를 사용하거나 환기 및 유동 팬을 사용하고 있는 농가도 있었다. 온습도 조절은 스마트 팜 시스템을 도입한 농가를 제외하고 약 85%인 34개 농가에서 측창이나 환기팬을 작동시키는 제어패널만을 이용하여 조절하였고, 수동으로 측창을 개폐하고 있는 농가도 10%정도인 4개 농가가 있었다. 보온 및 난방의 경우, 전체 대상 농가가 수막을 이용하고 있었다. 이 외에 필요에 따라 기름 및 전기보일러, 방열 램프 및 부직포 등을 병행하여 이용하는 농가도 다수 있었다.

Nowadays, many innovative marketers can leverage the augmented reality (AR) technology to create special experiences, offer more interactive advertising, as well as provide new ways to online shopping, especially for mobile marketing. The beauty industry occupies a large proportion in the fashion market and has become its essential part. For the fashion and beauty industry, consumers are willing to have the same level of experience online as when they are shopping offline. Accordingly, many brands develop mobile applications with AR capabilities that provide mobile AR services offering special experience. This new approach to mobile shopping eliminates the risk of shopping when consumers choose products, while indirectly changing consumer purchase behavior and lifestyles. However, relevant evidence about the AR service provided by mobile applications in the fashion and beauty industry remains to be scarce. To fill this gap in the literature, the present study seeks to explore the impact of the mobile AR technology on the consumer perception of the beauty brands and the changes in consumer’s behavior. In terms of the methodology, a semi-structured interview approach is employed. The results of the present study demonstrate that the effect of using the mobile AR technology varies according to the differences in consumers’ cognition and attention to beauty products. The playfulness provided by the mobile AR technology is a key factor for consumers to better understand and experience the brand, and consumer ROI is an important factor for consumers to purchase using the mobile AR service. At the same time, the degree to which the AR technology is mature affects consumer experience of the product. Surprisingly, our results suggest that the use of the AR technology has a certain educational effect on consumers, especially on those who are not good at make-up or have a low level of understanding of beauty products.

In recent years, maintaining transparency has become a trend among brands, and a better level of supply chain transparency has been demonstrated to positively affect consumer environmental concern and conscious behavior. Consumers may accept transparency efforts as a signal of the brand goodwill and perceive it as a visibly sustainable effort that can convert brand trust. In the information transparency trend, eco-certification plays an important role as a tool to inform consumers about sustainability. However, facing large amounts of information, consumers spend much time filtering information, so the accuracy of the obtained information can be compromised. The Higg index is a sustainable verification platform that reveals the entire activities of supply chains. However, most consumers are facing an overload of information that could confuse their processing of any information. In this context, the present study seeks to examine the effect of business transparency to conscious consumer behavior and purchase intention. Second, this study deals with the moderating effects of sustainable knowledge on the relationship between business transparency, environmental concern, and brand trust. Third, we explore the effects of high and low level of consume knowledge of sustainability on the relationship between business transparency and brand trust. In terms of the methodology used in the present study, an off-line survey of Korean consumers was conducted. SPSS 21.0 was used for data analysis aiming to test the proposed model and research hypothesis. The mains results of this study are as follows. First, business transparency has a positive effect on environmental concern, brand trust, and consumer willingness to conscious behavior. Second, consumer sustainable knowledge has a moderating effect on business transparency for environmental concern and brand trust. Taken together, the findings of the present study provide meaningful implications for marketers by highlighting the importance of transparency and introduction of a transparent eco-certification for communication with consumers. To successfully influence consumer willingness to assume conscious behavior, brands are advised to provide standardized transparency labels, rather than complicated information.

In this paper, the authors theorize and investigate empirically how the emerging technological developments of virtual reality convey the potential to augment future experiences of fashion consumption. This study is informed by previous studies that have discussed the role of fashion discourses and technology consumption within consumer experiences. Using the ZMET technique, the authors conducted a field study that empirically explored how virtual reality augments consumer experiences of fashion shows, hereinafter referred to as virtual fashion shows (VFS). Three themes have merged from our analysis: VFS as an agent of democratization, VFS as embodied escapism, and VFS as posthuman liminality. The implications of these findings for fashion consumer research and practice are discussed at the end.
