The red-eared slider (Trachemys scripta elegans) is the one of the most popular pets, and the most commonly traded species in the world. It is designated as an ecosystem disturbance species that has been managed in South Korea. To date, no reports of natural or anthropogenic migration and spreading of T. s. elegans in South Korea are available. In the present study, we estimated the expected route and the movable path of one female T. s. elegans found in Namsan-myun, Gyeongsan-si, Gyeongsangbuk-do. Based on the movable path, the potential destination of the female turtle was estimated to be about 282 m and 468 m away. Therefore, the moving distance of the red-eared slider to the nearest water system will be at least 606 m and at most 792 m. Our results provide the first evidence about the natural migration and spreading of exotic turtles. This study can serve as a basis for the management and countermeasures against the introduced of T. s. elegans and other exotic species in South Korea.

Interferon-tau (IFNT) is known as a major conceptus protein that signals the process of maternal recognition of pregnancy in ruminants. Also, multiple interferon genes exist in cattle, However, molecular mechanisms of these bovine IFNT (bIFNT) genes whose expressions are limited have not been characterized. We and others have observed that expression levels of bovine subtype IFNT genes in the tissues of ruminants; thus, bIFNT1 and other new type I (bIFNTc1/c2/c3) gene co-exist during the early stages of conceptus development and non-trophoblast cells. Its genes transcription could be regulated through CDX2 and ETS2 and JUN and/or cAMP-response element binding protein (CREB)-binding protein (CREBBP) expression, a transcription factor implicated in the control of cell differentiation in the trophectoderm. Bovine ear-derived fibroblast cells, were co-transfected with luciferase reporter constructs carrying upstream (positions -1000 to +51) regions of bIFNT1 and other new type I gene and various transcription factor expression plasmids. Compared to each - 1kb-bIFNT1/ c1/c2/c3-Luc increased when this constructs were co-transfected with CDX2, ETS2, JUN and/or CREBBP. Also, Its genes was had very effect on activity by CDX2, either alone or with the other transcription factors, markedly increased luciferase activity. However, the degree of transcriptional activation of the bIFNTc1 gene was not similar to that bIFNT1/c2/c3 gene by expression plasmid. Furthermore, Sequence analyses also revealed that the expression levels of bIFNT1/c2/c3 gene mRNAs expression were highest on day 17, 20 and 22 trophoblast and, Madin-Darby bovine kidney (MDBK), Bovine ear-derived fibroblast (EF), and endometrium (Endo) non-trophoblast cells. But, bIFNTc1 mRNA had not same expression level, bIFNTc1 lowest levels than those of IFNT1/c2/c3 gene in both trophoblast and non-trophoblast cells. These results demonstrate that bovine subtype bIFNT genes display differential, in the trophoblast and non-trophoblast cells.

Variance of conceptus interferon tau (IFNT), produced by the embryonic trophectoderm, is known as a major conceptus protein that signals the process of maternal recognition of pregnancy in ruminants, essential for the maintenance of early pregnancy. Similar to other IFN genes such as IFNA and IFNB, multiple IFNT genes are present. However, some kinds of IFNT genes actively transcribed and regulated in bovine conceptuses have not been well characterized. In this study, during the course of bovine IFNT gene transcription through the use of next generation sequencer SOLiD3, revealed that among 38 IFN genes registered, only two transcripts, IFNT1 and IFNTc1, were found in conceptuses during early pregnancy. Also, to identify a transcription factor(s) involved in the regulation of IFNT genes, mRNAs for various known transcription factors were investigated by real-time PCR in conceptus tissues, respectively. Furthermore, compared to the IFNT genes, IFNT1 and IFNTc1 had same active levels, which were previously shown to correlate with the appearance of effective antiviral activity. However, the expression levels of these Luc activities differed. Bovine ear fibroblast (EF) cells were cotransfected with luciferase reporter constructs carrying upstream (–631 to -51) promoter regions of IFNT1 or IFNTc1 and various transcription factor expression plasmids, CDX2, AP1(JUN), ETS2 and/or cAMP-response element binding protein (CREB)-binding protein (CREBBP). CDX2, either alone with the other 2 transcription factors, was found to increase luciferase activity approximately 14- and 11-folds, respectively. The degree of transcriptional activation of the IFNTc1 gene was not similar to that IFNT1 gene by AP1, ETS2 or/and CREBBP, expression plasmid. These results suggest that two isoforms of bovine conceptus IFNT genes are regulated differently in conceptuses during early pregnancy.

The Semi-Rigid Pavement (SRP) mixture is composed of Gap Graded Asphalt (GGA) mixture (air void = 20~28%) and cement paste. By inserting cement paste into voids in GGA mixture, SRP can provide not only flexibility but also rigidity characteristics on pavement performance. SRP can mitigate pavement surface temperature increase during summer session, provide better smoothness and mitigate rutting distress due to heavy weight vehicles, successfully. In Japan, SRP is widely applied in cross section area, heavy vehicle parking lot and highway ticketing booth in highway network system. In South Korea, SRP was introduced and applied since 2005. However, still more researches and studies are needed to understand material characteristics and improve performance of SRP. Moreover, the current SRP system in South Korea merely follows and adapts the aggregate gradation information from Japan which needs to be amended and customized into original material (i.e. aggregate, binder and cement) situation of South Korea. In this paper, SRP system based on Stone Mastic Asphalt (SMA) mixture design originated from Korea Expressway Corporation (KEC) and enhanced cement paste with addition of fly-ash and slags was developed. In addition, an optimized proportion between asphalt mixture air voids and cement paste amount with consideration of economic benefit was introduced. Based on field evaluation process it can be said that the newly developed SRP system can successfully adapted not only in static site on highway: parking lots or ticketing booth, but also in dynamic site on highway: driving and wheel path.

The composition of the deicer sprayed on the highway is spreading over the highway by the scattering or snow removal activity, or car movement and consequently affecting the vegetation environment around the highway. These are the cause of the damage of fruit trees and crops, and also the cause of corrosion of highway structures. The goal of this study is to estimate the detected range of deicer components from a highway. The concentration of the deicer components in gauze and soil were investigated according to the crossing distance from the highway. The data collected were then used to estimate the concentration range of deicer components in a rage of distance up to 100 m from the highway where the deicer was spread. The sample time and weight of gauze were measured before and after installation, and the soil was collected at more than three points in parallel with the highway at the gauze installation point. The components in gauze and soil were investigated in addition to the deicer components (Ca2+, Na+, Cl-) as well as Mg2+ and K+. As Ca2+ and Cl- components of deicer were affected by agricultural use, Na+ component was selected as a tracer and further SAR (Sodium Adsorption Ratio) of soil was analyzed to examine the degree of influence on vegetation indirectly. The gauze concentration was evaluated by the concentration of the deicer ingredient at the background concentration of the blank gauze. The total amount of the deicer sprayed in the study road for 4 months (winter season) was about 93 ton/km. In the gauze test, the spread of the deicer was detected at a distance of 100 m in study area, but the concentration of the deicer in the gauze by distance decreased rapidly within 10 m from the highway. And concentration of the deicer components in gauze and soil came down after rainy season (August ~ Sep.). The results showed that the components of the deicer could be spread widely by the wind. The effective range of the deicer on vegetation based on SAR in soil was estimated to be less than 20 m from the highway. This study examines the concentration changes of the deicer components in gauze and soils and shows that deicer components sprayed on the highway are accumulated and moved over time by wind, snow removal, terrain, water system and land use around the highway.

The tobacco cutworm, Spodoptera litura(Fabricius) is serious pest that hurts tomato crops, actives long time of the year. Without pesticide applications, sex pheromone delta traps through experiment first and second half setting during cultural seasons in glasshouse and greenhouse. We investigated captured number of S. litura both in and out side of the two type of tomato cultivated greenhouse. As a result of investigation, captured number of S. litura showed the wave and three high peak typed graph throughout 10 months experiment. First time expression of S. litura was late April in outside installed traps and after that occurrence rate increased gradually until late August. In september, the rate decreased remarkably to middle November in both in and out side treated traps. The result also expressed that captured average number of S. litura in inside of the greenhouse were 8~10 units, and were 15~20units in outside treated traps. Simultaneous installation of internal and external sex pheromone traps succeeded in eliminating a considerable number of S. litura male moths, and the number of larvae was expected to be considerably reduced. Consequently in the experiment, captured male number of S. litura were about 220 units in outside, on the other about 80 of S. litura captured in inside installed traps.

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.

Supply and demand patterns have dynamically changed in recent years due to the increased global competition. Firms have selected quality and price as competition components and have accomplished corporate innovation in order to achieve competitive advantage. Innovation has been recognized as the way to enhance corporate competitiveness and to continuously grow in churning global competition (Homburg, Schwemmle, & Kuehnl, 2015; Moon, Miller, & Kim, 2013). Although innovation becomes a common means to improve a firm’s performance, it has the limitation of achieving a firm’s strategic goal as a long-term strategy. Thus, firms need to have more fine-grained strategies to survive in dynamically changing business environment, such as design innovation (Moon et al., 2015). For example, Apple has produced its products (e.g., iPhone, iPod and iPad) focusing on innovative product design to influence consumer purchase intention. Design can lead to a distinct competitive advantage (Bolch, 1995). Furthermore, product design can be used by firms to create amd enhance brand recognition, as well as to increase firms’ value (Mozota, 2002). Brand experience positively influences customer satisfaction and brand loyalty (Brakus, Schmitt, & Zarantonello, 2009). Thus, we assume that design experience and product innovation have a positive effect on consumers’ purchase behavior and customer value. However, while the importance of design innovation is recognized, it is not easy to apply the design innovation to marketing due to the lack of relevant research in the field. In fact, relevant research on the influence of innovative new product design and design experience on customer value is scarce. Therefore, the purpose of this study is to investigate how brand experiences and innovative product design affect customer value. Successful innovation is accomplished by identifying customer needs first and developing innovative products to satisfy their needs (Hauser et al., 2006). Design is seen as the core of innovation and the moment when a new object is conceived of, devised, and shaped in a prototype form (Landwehr, Wentzel, & Herrmann, 2013). Verganti (2008) studies the concept of "user-centered design," which describes how companies can use design to improve their relationships with users and develop a better understanding of user needs. In this research, design innovation has three dimensions: aesthetic attributes, feature attributes, and emotional attributes. First, aesthetic attributes focus on the product design itself. The aesthetic appearance of a product has a large bearing on its potential market share (Liu, 2003). Second, feature attributes focus on the product features and functional aspects that are required to satisfy customer needs. Feature attributes enable performance that can give results in the operating process (Crawford & Di Benedetto, 2007). Third, emotional attributes focus on consumers’ feeling when they purchase a new product to satisfy their needs. Emotional attributes are generated by consumers’ experience when they purchase a new product in the store. The more the product design satisfies customer's emotional needs, the more customers’ attention is attracted to the purchase of a product (Mokarian, 2007). A product satisfying the aesthetic, feature, and emotional attributes through design innovation provides a new experience to customers (Desmet & Hekkert, 2007). A consumer’s purchase decision making is affected by both direct and indirect experience of using the product and the function of product (Brakus, Schmitt, & Zarantonello, 2009). Therefore, a designer comes to design the product, taking an interest in the experience that the product gives besides its shape and function. Product experiences occur when a customer interacts with the product ̶ for example, when customers search for, examine, and evaluate products (Hoch, 2002). The product experience can be direct, i.e. when there is physical contact with the product (Hoch & Ha 1986) or indirect, i.e. when a product is presented virtually or in an advertisement (Hoch & Ha 1986; Kempf and Smith 1998). Brand experience can be split into four dimensions (sensory, affective, intellectual, and behavioral), which are differentially evoked by various brands (Brakus, Schmitt, & Zarantonello, 2009). According to previous studies, these four experience dimensions (sensory, affective, intellectual, and behavioral experience dimensions) have an effect on customer satisfaction and customer loyalty. Customer value can be defined as the trade-off between the benefits and sacrifices as a customer purchases a product or service from a supplier (Ulaga & Chacour, 2001). Ulaga and Chacour presented three dimensions of customer value: product-related components, service-related components, and promotion-related components. The researchers argued that customer value could be an important strategic marketing tool to clarify a firm's proposition to customers. Product-related components are intrinsic product characteristics. Product quality is a key factor of relationship value (Ulaga, 2003). Customer value consists of product value and service value. Customer value can be enhanced by quality, diversity, payment, and service quality and decreased by price, convenience, and risk (Jarvenpaa & Todd, 2003). Service-related components include all aspects of service associated with the product. Various service components play an important role in differentiating a supplier's offering (Narus & Anderson, 1996). Promotion-related components include all items used to promote the product to the customer. For all purchasing processes, it is necessary to assess the perceived customer value, such as service quality and promotional quality (Qualls & Rosa, 1995). In the present study, we conducted a research survey with 300 subjects and analyzed the data. In order to test the reliability of questionnaire, Cronbach's alpha was used. In order to test the validity, an exploratory factor analysis was conducted. Measurement was made for 3 variables, i.e. design innovation, design experience, and customer value. Three variables (aesthetical attributes, feature attributes, and emotional attributes) were used for design innovation. Three types of attributes were introduced for a mobile phone design innovation. Four dimensions (sensory, affective, intellectual, behavioral) were measured using a technical design experience and a humanistic design experience. Three variables (product-related customer value, service-related customer value, and promotion-related customer value) were employed for customer value. The results of the analyses demonstrate that design innovation has a positive effect on design experience, while design experience has a positive effect on customer value. Aesthetic attributes of design innovation have a positive effect on technical design experience and humanistic design experience. Feature attributes have a positive effect on the technical design experience and the humanistic design experience. Emotional attributes have an effect on the technical design experience and the humanistic design experience. The technical design experience has a positive effect on product-related customer value, service-related customer value, and promotion-related customer value. The humanistic design experience has a positive effect on product-related customer value, service-related customer value and promotion-related customer value. This study will make it possible to empirically examine how customer's experience in design innovation affects customer value. Our results will provide a theoretical foundation for examining a relationship between variables regarding how design innovation influences customer value through design experience. It is intended to give a direction as to the design innovation of firms by clarifying and presenting antecedent factors having an effect that design innovation produces on customer value. The results of the present study will inspire designers to design in consideration of design experience. Finally, our study will provide marketers with guidelines as to how design experience can influence customer satisfaction and loyalty.

A fashion social platform is a system that leverages the power of social connectivity to enable individuals to interact, accumulate information and create social values in fashion marketing. Fashion social platform participants, through their collective intelligence, give social platforms essential competence to solve economic and social issues, gather social capital, and create customer value. This study highlights the critical value of fashion social platforms and explains the relationships between knowledge sharing, social capital, and sustainable customer value. They examine (1) the effects of social network properties on knowledge sharing in fashion social platforms, (2) the effects of knowledge sharing on social capital, and (3) the effects of social capital on customer value in fashion social platforms. In the context of social platforms, this study clarifies the concept of customer value, the role of knowledge sharing, and the relationships between social capital and customer value. The study constructs a theoretical model regarding fashion social platforms and sustainable customer value that offers possible implications for fashion marketing practitioners.

These days, thanks to lots of smart devices and advanced communication technologies, consumer’s recognition and relations have been changed. They, beyond relying on information and services which are produced by experts, produce information and knowledge by themselves via SNS or web that they want to know. As consumer’s recognition is changing like this, SNS is evolving into social platform. Therefore, this paper is intended to clarify overall relationship between network characteristics in social platform, knowledge sharing, social capital, social innovation and customer’s value. This paper has clarified influences between variables related to consumer’s behaviors in social platform and the results are summarized as following: First, network characteristics in social platform are found to positively affect knowledge sharing efforts of social platform. Second, knowledge sharing has been found to positively affect social capital and innovation in social platform. However, enjoyment in helping others i.e a sub variable is found to positively affect social capital and innovation through anticipated reciprocal relationships. Third, social capital and innovation in social platform have affected customer value in social platform positively. Consequently, this paper is intended to solve various problems found from overall societies and industries through social innovation and also to advance them. For these purposes, social platform is believed to prompt sharing idea and knowledge based on interactions between users and social relationship. These actions become social capitals resulting in social innovation. Moreover, these would create new businesses and marketing opportunities across various areas in the processes that innovative activities form customer values.

True hermaphrodites are animals of equivocal sex in which both male and female gonads develop simultaneously. The frequency of true hermaphroditism is higher in pigs than in other domestic animals. Two Korean pigs were diagnosed with true hermaphroditism showing ovotestes, epididymes, penes, and uteri. Histomorphologically, the testicular tissues consisted of Sertoli cells that were devoid of spermatogenic germ cells and showed proliferation of interstitial cells. However, the uteri were of normal architecture and had well-developed uterine endometrial glands. The samples were 38, XX female karyotype without the sex-determining region Y (SRY) gene. The findings of this study could contribute to the understanding of true hermaphroditism in the Korean pig industry. * This work was supported by a grant (Code# PJ008148) from BioGreen21 Program, Rural Development Administration, Republic of Korea.

Experiments were conducted in order to assess the healing effect of bee venom (BV) cream on full-thickness skin wounds in rabbits. BV cream was compared with silver sulfadiazine (SS) as a topical medicament against a control on experimentally created full-thickness wounds. Two wounds measuring 2 × 2 cm were created bilaterally (four wounds/rabbit) on the dorsolateral aspect of the trunk of seven New Zealand white rabbits. Wound treatments were evenly distributed on four sites, using a Latin square design. The contact layer of wounds was treated with physiological saline (control), SS cream, and BV cream over a period of 28 days. Assessment of wound healing was based on scab hardness, wound exudates, wound area, unepithelialized granulation tissue, and histopathological findings. Topical application of BV and SS creams to wounds resulted in reduced inflammation, debridement of necrotic tissue, and promoted granulation and epithelialization. Wound healing was faster, with statistical significance in BV and SS treatments, compared to the control (P<0.05). Treatment with BV evoked an anti-inflammation effect in a rabbit model. BV cream produced a wound healing effect similar to that of commercially available SS cream. Anti-inflammation effect as a topical treatment with BV cream appears to be better than that with SS cream. These results suggest that topical application of BV cream may be an alternative treatment for full-thickness skin wounds.

Beauveria bassiana is one of universal insect pathogenic fungi that have been used for biocontrol agent against insect pests. This fungus has also been studied for medicinal use. To meet for commercial use, the artificial production of the fruit body of this fungus has been established by the Mushtech Co in Korea. This study was carried out to define the morphological features of the fruit body of B. bassiana developed through artificial cultivation. For the observation of mycelia growth, B. bassiana was cultured on the Sabouraud Dextrose agar plus Yeast Extract(SDAY), nut-supplemented medium, and Fe ion-supplemented SDAY at 25℃ for 15 days. The variation of colony color was observed between the different media. Strong pigmentation was observed on Fe ion-supplemented SDAY. To investigate morphological characteristics of fruit body, geminating ascospores and vegetative hyphae were observed though light microscopy and scanning microscope. During seven weeks of cultivation period, the development process of apical fertile part of stromata can be separated by the development stage of perithecia. To understand the developing process of fruit body at the transcript level, investigating process of distinct gene expression according to cultural condition and developmental stage was discussed.

운간초의 분화 품질을 향상시키기 위하여 ‘Kumoma’ 와 ‘Kumoma-Gusa’ 두 품종의 생장과 개화에 미치는 영향을 구명하고자 식물생장억제제 (PGRs) 4종을 처리 하였다. 식물생장억제제 종류와 처리농도는 paclobutrazol (10, 20, 40, 80 mg·L-1), flurprimidol (5, 10, 20, 40mg·L-1), daminozide (500, 1000, 2000, 4000mg·L-1), chlormequat (50, 100, 200, 400 mg·L-1)이고 엽면살포 와 토양관주 방법으로 처리하였다. Paclobutrazol 40 mg·L-1 처리는 운간초의 두 품종에서 초장과 화경 장을 줄이는데 효과적이었다. ‘Kumoma’ 품종에서, paclobutrazol 40 mg·L-1 엽면살포와 토양관주 처리방 법은 초장을 각각 12.6, 12.5 cm로, 화경장은 3.4, 3.3 cm로 줄일 수 있었다. ‘Kumoma-Gusa‘ 품종에서 는 paclobutrazol 토양관주는 처리 농도가 증가함에 따라 초장은 13.2-10.7 cm, 화경장은 3.9-2.0 cm까지 줄일 수 있었지만 꽃의 수는 대조구와 비교했을 때 현 저하게 감소하여서 20개까지 감소하였다. Flurprimidol 20mg·L-1 스프레이와 토양관주 처리는 두 품종 모두 초장과 화경장을 줄일 수 있었다. ‘Kumoma’ 품종에 서 flurprimidol 10 mg·L-1 스프레이 또는 토양관주 처리는 개화 품질을 향상시킬 수 있었고 대조구와 비 교해 꽃의 수는 44.7개 이상, 출하 일수는 5일 정도 빨리 출하 할 수 있었다. ‘Kumoma-Gusa‘ 품종에서 PGRs처리에 의한 초장 과 화경장 억제효과가 가장 큰 것은 paclobutrazol 80mg·L-1과 flurprimidol 40mg·L-1 이었고 paclobutrazol 과 flurprimidol 스프레이와 토양관주 처리에서 각각, 초장은 10.7, 9.9 cm, 화경장은 2.0, 1.5 cm 로 생장 억제효과가 가장 큰 것을 알 수 있었다. 그러나 flurprimidol 40 mg·L-1 토양관주 처리에서 출하일수는 농도에 따라 3-13일 정도 대조구보다 늦어졌고 꽃의 수는 15.6개로 가장 적은 것을 관찰 할 수 있었다. 두 품종 모두에서 daminozide 처리는 초장과 화경장 이 줄어들지 않았지만 ‘Kumoma’ 품종에서는 대조구 와 비교했을 때 꽃의 수가 증가하였다. Chlormequat 처리는 paclobutrazol 과 flurprimidol 처리와 비교했 을 때 화경장 감소효과는 작았고 처리 식물의 잎은 다른 처리에 비해 연한 녹색을 보여주었다. 두 품종 모두에서 chlormequat 과 daminozide 처리는 생육과 개화 품질에 효과적으로 영향을 주지는 않았지만 꽃의 수는 모든 처리농도에서 41개 이상을 보여주었고, ‘Kumoma-Gusa’ 품종에 chlormequat 토양관주 처리는 최대 꽃의 수 63개를 볼 수 있었다. 이번 결과들은 paclobutrazol 과 flurprimidol 처리가 운간초 분화의 품질 향상을 위한 화경장의 생육을 조 절하는 생장억제제로서 사용 될 수 있음을 보여 주었 고, ‘Kumoma’ 품종에서는 paclobutrazol 40 mg·L-1 스프레이는 생육특성을, flurprimidol 10 mg·L-1 토양관 주 방법은 개화관련 특성의 품질을 향상시키는 생장억 제제의 농도로 추천 될 수 있고, ‘Kumoma-Gusa’ 품종 에서는 flurprimidol 20mg·L-1 스프레이와 flurprimidol 5mg·L-1 토양관주 방법이 운간초 분화의 생육특성과 개 화품질을 향상시키는 생장억제제의 농도로 추천 될 수 있다.

원자전달 라디칼 중합을 이용하여 poly(epichlorohydrine) (PECH)를 주사슬로 한 양친성 가지형 공중합체를 합성하였다. PECH로부터 poly(methyl methacrylate)(PMMA) 및 poly(butyl methacrylate)(PBMA)의 가지형 중합이 성공적임을 1H NMR과 FT-IR분석을 통해 확인하였다. 합성한 가지형 공중합체에 KI나 LiI 염을 도입하였을 때, ether 신축진동 피크가 낮은 wavenumber영역으로 이동하였으며, 이는 배위결합 상호작용 때문이다. PECH-g-PBMA 복합체의 이온 전도도는 PECH-g-PMMA 복합체에 비해 항상 높게 나타났는데, 이는 고무상인 PBMA 사슬의 높은 이동성으로부터 기인한 것으로 확인되었다. 최고 이온전도도 값은 질량비 10 wt%의 KI가 도입된 PECH-g-PBMA 전해질체에서 2.7 × 10 -5 S/cm로 나타났다.
