최근 들어 여러 산업 분야에 활발히 사용되고 있는 고분자 분리막은 화학구조의 제어나 제막공정에서의 물리적 특성 제어뿐만 아니라 다양한 소재와 혼합된 복합막 제조를 통해서 고유의 특성을 부여할 수 있는 장점을 가지고 있다. 본 연구에서는 분리막 제조 시에 누에(Bombyx mori)가 생산한 친환경 천연소재로 활용 가능성이 넓은 실크 고분자의 복합막 제조 시 다른 소재와의 혼화성 지표로 사용할 수 있는 용해도 파라미터를 분자동역학을 이용하여 계산하였다. 역시 친환경성 및 생체적합성을 갖고 있는 polyvinylalcohol (PVA)의 용해도 파라미터를 분자동역학을 이용하여 계산 후 서로 비교하였을 때 두 고분자 소재가 비슷한 용해도 파라미터 값을 갖는 것을 확인하였다. 결론적으로, 두 고분자가 서로 잘 혼합될 수 있음을 이론적으로 증명하였고, 실제 실험을 통해서도 이를 확인할 수 있었다.

본 연구는 실크로드의 역사를 다시 조명하여 실크로드의 주역이었던 고조선의 아름다운 실크의 감성을 찾아보고 잘 알려지지 않은 우리의 역사를 알아보고자 한다. 연구 방법은 고서, 서적, 논문, 유적지 발굴 유물들을 분석하는 다양한 접근을 시도하였으며, 유물에 대한 자료는 다양한 서적과 논문 그리고 인터넷을 통해 관련 유물사진들을 수집한 2차적 자료를 분석하였다. 연구문제는 다음과 같다. 첫 번째, 고대 실크로드와 고대 동양에서 발견된 고조선의 경금의 실크 생산 환경을 조사한다. 두 번째, 고조선의 경금의 고도의 제작기술에 대해 조사한다. 본 연구 결과는 다음과 같다. BC 4500년 홍산문화의 동이족으로부터 발견된 옥으로 만든 누에를 통해 고조선의 실크 생산 시기를 추론할 수 있다. 신장자치구 누란, 아스타나, 니야 등에서 경금이 많이 출토되었으며 가장 오래된 경금은 기원전 11세기경으로 서 발해만 고조선의 수도 중 하나였던 조양에서 발굴된 것이다. 서양의 브로케이드 및 다마스크의 기원으로 보이는 경금은 고조선의 수평 사각직기인 제화루기로 고도의 제직기술의 발전된 직기를 통해서 생산되었다. 이와 같은 결과를 통해 고대 실크로드의 특징은 기원전 5-6세기경 발해만 유역의 고조선에서 생산한 경금 견직물이라고 추측할 수 있었다. 한나라의 사직기나 서아시아의 수직직기로 경금 제직이 불가능하며 고조선의 제화루직기과 함께 고도의 제직기술 을 통해서만 경금이 탄생될 수 있었다. 이와 같은 연구결과를 토대로 고대의 실크에 관한 역사 연구를 이어나가기 위해 중요한 초석이 될 것이며, 앞으로 고대 실크에 관한 후속 연구에 필요한 기초 자료로 제공되기 바란다.

In order to facilitate its Belt and Road Initiative, China has issued dozens of policy documents and detailed guidelines, improved its legal and supervisory systems, and taken full advantage of all existing cooperation mechanisms at the bilateral, regional, sub-regional and multilateral levels. The current cooperation mechanism is characterized by non-systemicity, which makes it dependent upon other existing regional cooperation mechanisms. In fact, it has no uniform institutional structure, nor any dispute settlement mechanism. Although this non-systematic approach is based in China’s successful experience in opening up to outside influence and in the flexibility that enabled its rise to global prominence, this very flexibility also poses challenges to the implementation of the Belt and Road Initiative by leaving it open to conflict with existing regional cooperation mechanisms. Therefore, to ensure the success of the Belt and Road Initiative, China should undertake a systematic plan for implementation by establishing a comprehensive legal framework; streamlining paths to economic cooperation; and institutionalizing the cooperation mechanism with a formal dispute settlement mechanism at its core.

본 연구는 친환경적이고 감성적인 패션상품의 색채기획을 위한 자료를 제공하고자 수행되었다. 쪽과 괴화로 복합 염색 후 무매염 견직물과 4종의 매염제(Al, Cu, Fe, Zn)를 처리한 견직물에 대하여 색채특성을 측정하였다. 또한 복합염색 후 매염처리된 연두색 견직물에 대하여 여대생을 대상으로 색채감성과 색채 선호도를 조사하였으며, 색채 특성과 색채감성이 색채 선호도에 미치는 영향을 분석하였다. 쪽/괴화로 복합염색된(무매염) 견직물은 선 염색한 쪽 농도가 10 g/ℓ이면 녹색, 쪽 20 g/ℓ을 사용하면 청록색을 나타내었으며, 4종의 매염제를 사용하여 처리시 거의 모든 경우 연두색을 나타내었다. 연두색을 나타내는 복합염색된 견직물 10종의 색채감성을 요인분석한 결과, 유쾌성, 품위성, 편안성 요인으로 분류되었으며, 이러한 색채감성은 쪽 농도와 매염제의 종류에 따라 대부분 유의한 차이를 보였다. 또한 복합염색된 연두색 견직물의 색채특성과 색채감성요인 간에는 대부분 유의한 상관성을 보여, L＊값, b＊값, C＊값이 크고 a＊값이 작을수록 유쾌성과 편안성 감성을 더 강하게 느끼며, L＊값이 작고 a＊값이 클수록 품위성 감성을 더욱 느끼는 것으로 나타났다. 따라서 쪽과 괴화로 복합염색하고 매염처리한 연두색 견직물의 색채감성요인을 예측변수로 활용할 수 있는 색채 선호도 예측 회귀식이 제안되었다.

This study was designed to optimize ethanol extraction process of unfertilized corn silk (UCS) to maximize phytochemical contents and bioactivities. The response surface methodology (RSM) with central composite design (CCD) was employed to obtain the optimal extraction conditions. The influence of ethanol concentration, extraction temperature and extraction time on total polyphenol contents, total flavonoid contents, maysin contents, 2,2-diphenyl-1- picrylhydrazyl(DPPH) radical scavenging activities and tyrosinase inhibition were analyzed. For all dependable variables, the most significant factor was ethanol concentration followed by extraction temperature and extraction time. The following optimum conditions were determined by simultaneous optimization of several responses with the Derringer’s desirability function using the numerical optimization function of the Design-Expert program: ethanol concentration 80.45%, extraction temperature 53.49°C, and extraction time 4.95 h. Under these conditions, the predicted values of total polyphenol contents, total flavonoid contents, maysin contents, DPPH radical scavenging activity and tyrosinase inhibition were 2758.74 μg GAE/g dried sample, 1520.81 μg QUE/g dried sample, 810.26 mg/100g dried sample, 56.86% and 43.49%, respectively, and the overall desirability (D) was 0.74.

The aim of this study was to evaluate the effects of microencapsulation on the water absorption, DPPH radical scavenging activity (DRSA), hydroxyl radical scavenging activity (HRSA) and tyrosinase inhibition activity (TIA) in corn silk extracts. The lowest value (0.20) of water absorption index (WAI) and the highest value (95.23%) of water solubility index (WSI) were maltodextrin+cyclodextrin microencapulated corn silk extracts (MD+CD) and cyclodextrin encapulated corn silk extracts (CD), respectively. The 18.60% for DRSA value of control was increased to 89.25% for that of CD. The 16.89% for HRSA value of control was increased to 47.46%, and 7.16% for TIA value of control was increased to 39.35% for that of MD+CD, respectively. The MD+CD would be used for functional food and cosmetics materials as antioxidant and skin whitening agents. All investigated responses between control and treatment were statistically significant (p<0.05).

State of the Art: Sustainability Integration in the Luxury Fashion Industry Introduction to Luxury Fashion ‘Luxury’, which comes from the Latin word ‘luxus’, refers to exaggerated life, glamour, comfort and wealth (Dubois, Czellar & Laurent, 2005). In the ancient world, luxury was associated with wealth, exclusivity, and power. After the 17th century, European countries’ economic democratization contributed to the reduction of existing sumptuary laws. Trade increased and larger segments of the population began to afford luxury products. Consequently, luxury moved from being limited to serve the common good to being a satisfaction of private needs. At the end of the 19th century, following the second industrial revolution, luxury earned its modern meaning of being enjoyable beyond the necessities of life (Fionda and Moore, 2009). The democratization of luxury resulted in mass luxury in which luxury brands have extended themselves to affordable offerings (Cristini et al., 2017). Luxury was long associated with the premium quality (Brun and Castelli, 2013), whereas today the technical reproduction of luxury is indulged by mass-produced brands (Cristini et al, 2017). Thus, one could argue that commercial drivers have taken over the industry whereby executives are increasingly seeking ways to transform creativity into profitability. Accordingly, the luxury market has experienced noticeable growth. The global luxury goods market reached a value of € 1.081B, with a growth rate of 4%, in 2016 (Bain & Company, 2016). Nevertheless, despite growth and high profit margins, the global fashion market is affected by macroeconomic, socio-political and natural events. For example, the short-term doubling in cotton prices brought many problems in 2011. Furthermore, scarce natural resources and rising commodity prices greatly challenge the ability of luxury fashion companies to remain profitable. The new luxury paradigm of being more accessible challenges not only sustainability but also operational aspects. The reputation of the luxury industry suffers from consumer concerns over poor labour standards in production, blood diamonds, irresponsible gold-mining practices and animal cruelty in global production networks (Hennigs et al, 2013; Moore, 2011). We therefore question how and to what extent luxury could play a positive role in our mass-consuming generation to slow down the pace for materialism and to better implement sustainability in globally dispersed production networks. Whilst sociologists, marketing and branding experts, have shown interest in luxury management, researchers in the field of operations and supply chain management have paid little attention to the topic: the first paper in the field appeared less than a decade ago (Brun et al., 2008), and furthermore, as of January 2017, there appear to be only 87 papers published in Scopus-indexed journals with ‘‘supply chain OR oper*’’ AND ‘’luxury’’ in the keywords. Henceforth, the current financial, environmental, economic and cultural crises could be considered significant drivers for how luxury operations could be advanced in the move toward sustainability. The focus of this paper is luxury personal goods such as fashion and accessories. The Relevance of Sustainability for Luxury Fashion Following the supply chain revolution of the 1990’s (Mohanty and Prakash, 2013) and the removal of the Multi-Fibre Arrangement in 2005, the fashion industry has become a global force in production and distribution. Globalisation has led to increasing outsourcing of production by fashion companies to a network of suppliers and subcontractors. The industry is characterized by shorter product life cycles and highly volatile market demand (Choi, 2013) alongside downward price pressure, international sourcing, high product variety and low predictability (Perry and Towers, 2013). To this end, fashion companies rely on sophisticated information and logistics systems to remain competitive in the market. Nonetheless, the fashion industry is somewhat inflexible toward major external changes outside the organizations’ direct control (Kozlowski et al., 2015). There is also a potential conflict between corporate responsibility and overarching commercial pressures in the fashion industry (Perry et al., 2015). According to the definition of sustainable development by The United Nations World Commission on Environment and Development (WCED, 1987), current needs should be met without endangering future generations’ rights to satisfy theirs. Luxury fashion companies must therefore acknowledging resource scarcity and other sustainability issues, and take collective actions for an authentic shift to create unique and sustainable businesses. To be profitable and sustainable, “luxury companies must adjust their definition of excellence that is no longer associated with shallow glamour but with positive engagement and deeper values” (Hennigs et al, 2013, p.33). An Overview of Sustainable Supply Chain Management (SSCM) Sustainability in SCM has captured academics’ interest since the early 1990s. Despite the growing interest, some fundamental issues still need to be addressed to provide novel models. The majority of the practices that make up green supply chain management (GSCM) models are modifications of existing practices (Pagell and Wu, 2009). However, earlier studies also stress that these programs might not be sufficient to become sustainable. Hence, it would be insightful to examine which components and which practices are required to make ‘sustainable’ chains. Social sustainability also requires deeper consideration. Wu and Pagell (2011) investigated how organizations deal with short-term pressures to remain economically viable during sustainability implementation, but did not consider social aspects of sustainability. Lee and Klassen (2008) identified the important drivers and enablers which promote environmental management capabilities in SME suppliers, but did not address social sustainability or specific measures for suppliers’ environmental management capabilities. Zhu and Cote (2004) and Vachon and Klassen (2006) demonstrated how to extend green practices, but again social aspects were not encompassed. Similarly, Caniato et al (2012) identified drivers that push companies to adopt green practices, various practices that could be used to advance environmental sustainability and environmental performance indicators measured by fashion companies. However, the social component was excluded. The recognition of corporate social responsibility (CSR) as a business activity is highlighted by the launch of ISO 26000; nonetheless, as illustrated earlier, extant SCM literature has mostly neglected the social aspects of sustainability. Despite a number of studies on aspects including social responsibility and consumer trust (Castaldo et al., 2008), sustainability reporting (Lozano and Huisingh, 2011), sustainable supply management (Ageron, Gunasekaran, & Spalanzani, 2012), and supplier selection problems (Jia et al., 2015), social issues demand more investigation (Perry and Towers, 2013). Sustaining an efficient global supply chain without compromising social responsibility (Perry et al., 2015). Embedding social and environmental management into SCM is needed yet challenging. Significant progress has been made in studies of the buyer-supplier relationship over the past decades, however despite some notable exceptions on green SCM (Zhu and Cote 2004; Zhu et al. 2008; Yu et al. 2014), the development of SSCM literature appears to focus on a single entity rather than the entire chain or network. Social and environmental performance of suppliers is an area of mounting concern, and collectively, sufficient coordination between supply chain partners is greatly needed. Many small and medium-sized suppliers encounter challenges in responding to environmental pressures due to limited capabilities and available resources (Lee and Klassen, 2008), and the most critical environmental and social issues in supply chains are generated by suppliers located in the second tier or further upstream (Tachizawa and Wong, 2014). Therefore, a holistic examination of the entire chain is required. In this vein, Pagell and Wu (2009) examined the chain as an entirety by explicitly addressing both environmental and social outcomes and by asking what unique behavioural patterns are needed for SSCM. However, the adoption of some of the practices is quite limited, which suggests the existence of additional contingencies. Their study called for future studies to explore the role of specific industries e.g. textiles. To this end, Ho and Choi (2012) investigated why fashion companies go green and evaluated sustainable supply chains. Nevertheless, the study was a single case study and did not consider potential differences in terms of antecedents affecting small and large companies. Curwen et al. (2013), interestingly, sought to document current challenges the fashion and apparel industry faces while developing sustainable apparel. Yet again, an imperative need arises to further explore the connections among product design, production processes and supply chain stages through a multidisciplinary approach. On the whole, the phenomena of sustainability has been interpreted in a variety of ways, ranging from a philosophical perspective to business management approaches (Ahi and Searcy, 2013), but more research is needed to show more than how to be ‘less unsustainable’. Traditional business research must go beyond studies focusing on profit with a rather short-term orientation and instead embrace components of how to create truly sustainable businesses. Considering the aforementioned gaps observed in the extant literature, the following research questions were formulated to investigate the phenomena of social and environmental sustainability at supply chain level within the luxury context, where ethical aspects are becoming increasingly critical for success (Brun and Castelli, 2013). RQ1: How do luxury fashion companies integrate sustainability into their supply networks? RQ2: How do contingent factors impact sustainability integration in luxury fashion supply networks? RQ3: Which behavioural patterns could be used to develop a sustainable supply chain configuration for the luxury fashion industry? Research Methodology Data was drawn from case studies of two Italian supply chains producing luxury silk and leather goods, encompassing 10 companies, with a focus on the individual supply chain as the level of analysis. These two supply chain were theoretically sampled to provide diversity in organizational characteristics and supply network relationships that could explain different approaches to the integration of sustainability into the entire chain. The research design followed Yin (1994) and previous studies in operations and SCM. Face to face interviews were conducted with senior managers of different functions in each supply chain during 2015-16. In most of the companies, responsibility for sustainability was divided and integrated into the jobs of multiple managers, meaning that there was no single individual assigned to sustainability. Additionally, the managers interviewed were often in charge of one or more functions, which helped reduce the number of interviews but increased interview content. The interview topic guide was developed from the literature review, and the theoretical constructs underpinning the interview protocol were then used to create an initial coding scheme for data. Data analysis was done inductively, by developing a framework from the cases while exploiting the theoretical concepts in the categorization of codes. The coding process was followed for all cases as an iterative process to assure consistency. Coding was not considered complete until a consensus was reached on each construct. Data analysis involved within and cross-case analysis. Results: Toward a Framework for Sustainable Luxury Supply Chains This study explored the luxury fashion industry from supply chain and operations management standpoint. Findings revealed seven key categories by which luxury fashion companies integrated environmental and social sustainability into their operations: Category 1: Sustainable product design, Category 2: Operations management, Category 3: Performance measurement, Category 4: Sourcing management, Category 5: Decent work and labour management, Category 6: Commitment to sustainability and organisational perceptions and Category 7: Longevity of suppliers. Firstly, natural resource scarcity was acknowledged by all 10 companies. To this end, some practices, including use of eco-friendly materials, hazardous chemical elimination, textile waste reuse, were applied to the fashion design stage with an attempt to mitigate the environmental impact of subsequent operations. Life cycle assessment (LCA was observed to be a significant tool among sample companies. Nonetheless, higher investment costs to employ more innovative solutions and to advance laboratory tests, higher prices for more ecological materials, and lack of knowledge in terms of fibre and textile components due to supply chain complexity prevented companies from advancing product stewardship. Regarding operations management, water emerged as a significant area where sample companies implemented incremental techniques, including natural tanning, on-site wastewater treatment, water purification and water reuse. Nevertheless, vertical integration, which was getting weaker in the luxury fashion industry, resulted in fashion companies having difficulties in the execution of their suppliers’ environmental performance. Practices implemented in this category were individual company attempts rather than collective action plans. It was not quite feasible to mitigate the environmental impact of independent networks where the buying firm outsourced its business functions to third party suppliers. In order to deal with lack of control and monitoring, sustainability must be understood as a concept to be integrated into the core business strategy with measurable indicators. Furthermore, traceability emerged as a pivotal topic. However, the complexity of global luxury fashion supply chains brought complications. Both supply chains showed that there was lack of knowledge about products’ production history. Due to globalization, countries with low operational costs appeared to leverage their competitive advantage. Changing market conditions resulted in the loss of, for example, silk production in Italy. Silkworm cultivation did not take place in Italy any longer, resulting in confusion regarding outsourced materials’ environmental and social records. High product variety and fragmentation of the production network made it difficult for companies to ensure full traceability. To this end, trust and knowledge transfer were weak, which could be improved to link non-economic goals with financial objectives. Another interesting result was that supplier audits were mostly made within first tier direct suppliers’ facilities. In some cases suppliers were provided with online self-assessment tools that were monitored by buying firms. Yet, buying firms and manufacturers required more efficient inspection methods and more realistic mitigation strategies. Ensuring social sustainability is hindered by complications such as lack of visibility and financial burdens. Consequently, technical and motivational dynamic capability development needed to be proactively initiated by focal companies. As stressed by earlier studies, sustainability must be a shared effort within all functions of a company and across its supply network. Sustainability could be disseminated across the chain only when all supply chain actors, including retailers, suppliers and sub-contractors, connect, understand and collaborate with each other. Correspondingly, it became clear that sustainability management required strong organizational commitment for which an alignment between financial and non-financial goals was greatly required. Hence, education and training activities received growing attention. In conclusion, the sample companies asked their supply chain partners to become sustainable for two main reasons, (i) to make the chain stronger, and (ii) to jointly learn and improve performance. Long-term relationships and supplier stability, as evidenced in the leather supply chains, could cultivate trust, which would result in advanced organizational and operational performance improvements. Supplier engagement and collaboration associated with knowledge dissemination could further enable companies to improve sustainability, and lastly innovation capabilities were imperative.

Based on the inner-effect mechanism of transport infrastructure and regional economic growth, this paper builds a specialized spatial weight matrix by utilizing the panel data from 31 provinces in New Silk Road Economic Belt (NSREB) and other areas from 2005 to 2014, and combines with the spatial panel model to analyze the spatial spillover effects of transport infrastructure. According to the analysis, the transport infrastructure plays an obvious lead role in regional economy growth alongside the NSREB, and the economic growth invigorates common development in surrounding regions. In addition, differences were observed among the different transport infrastructure with regard to their influences on regional economic development, as the highway transport affects regional economic growth to a larger degree than railway transport.

Natural dye extracted from Salicornia bigelovii was applied to silk fabrics by dip dyeing process. The dyeing properties and the functionalities of the silk fabrics were determined. Factors affecting the dyeing properties such as dyestuff concentration, temperature, time and pH were studied. The colorimetric parameters L*, a*, b*, and H, V/C values were measured to select the optimal mordanting conditions. The colorfastnesses of the dyed and mordanted fabrics were estimated for practical use; in addition, the antibacterial property, ultraviolet protection properties were evaluated. The dyeabilities of silk increased depending on the increasing dye concentration, dyeing time, and dyeing temperature. And optimum dyeing results were achieved when dyeing with 300% (o.w.f.) of dye concentration at 90℃ for 100 minutes and at pH 3. The dyed silk fabrics without mordants produced yellow (Y) color and showed yellow (Y) or green yellow (GY) colors depending on the mordants type. The light fastness of dyed and Al mordanted silk fabrics were found to be excellent, and the drycleaning and rubbing fastness were good. The dyed silk fabrics showed no antibacterial property, but Al and Cu mordanted silk fabrics showed 99.9% reduction rate. The ultraviolet protection properties of the dyed silk fabric was improved. And the ultraviolet protection properties of mordanted samples showed very good ultraviolet protection properties.

Chapter One (甲篇) of Yin Yang Wu Xing in “The Compilation of Mawangdui Silk Manuscript” (《長沙馬王堆漢墓集成》), which has been seriously damaged, still needs further adjustments. From line 1 to 16 (Jicheng Vol.1 p250-251) in Zhu Shen Ji Xiong, we delete two silk pieces and move 2 other pieces according to the Fan Yin Wen (反印文) in Chapter Xi (徙), Tian Di (天地) and Nv Fa (女發) (Ji Cheng Vol.1 p244-245). Some pieces have been added. New transcription can be given by those adjustments. We notice that figures in this chapter were pieced and numbered mistakenly. Some line numbers of transcriptions do not match their figures. In addition, some texts that can be read together were separated.

Building the 21st Century Maritime Silk Road is a new initiative for international cooperation. It will have a positive impact on the peaceful use of the South China Sea by encouraging a Code of Conduct to Parties in the South China Sea between China and ASEAN members; realizing a breakthrough of jointly developing oil and gas resources in the area; promoting comprehensive cooperation in maritime non-traditional security field; and providing a peaceful external environment for the South China Sea dispute settlement. The South China Sea dispute is a negative challenge to building the 21st Century Maritime Silk Road. However, the pace building should not be stopped because of it. In the future, the 21st Century Maritime Silk Road will be on the international consensus as an international legal regime. Also, it will improve the domestic legal system regarding building the 21st Century Maritime Silk Road for China as well as the countries along the Belt and Road, especially the ASEAN members.

In this study, the dyeing of silk fabric with Polygonum cuspidatum extracts was investigated. The contents of this study are as follows. First, the proper dyeing conditions were investigated by measuring the dye uptake (K/S value) that depended on the dyeing conditions when silk fabric was dyed with Polygonum cuspidatum extract. Second, the brightness (L), hue, and chroma differences that appear after mordanting with Al, Cu and Fe were investigated by measuring the CIELAB and Munsell values. And third, the colorfastness and antibacterial property were measured. When the silk fabric was dyed with Polygonum cuspidatum extract, the proper dyeing conditions were a colorant concentration of 90% v/v, a dyeing of time 100 minutes, a dyeing temperature of 70℃, and a dyeing of pH 3. In mordanting methods, the dyeabilities of post-mordanting were higher than those of premordanting. The hue value displayed yellow (Y) and yellow-red (YR) in cases of pre and post mordanting. The C value decreased by the mordanting of Polygonum cuspidatum extracts. Generally the colorfastness of mordanted fabrics was improved by mordanting. The dyed fabrics showed a 90.6% of Staphylococcus aureus reduction rate, and the dyed and mordanted fabrics showed 97.1% bacteria reduction rate. The dyed and mordanted fabrics showed above 90.5% Klebsiella pneumoniae reduction rate, and Cu mordant revealed the most effective bacterial reduction.
