최근 유기태양전지의 효율향상을 위하여 고분자의 PEDOT:PSS 양극(Anode) 버퍼층이 널리 사용되고 있다. 그러나 고효율 태양전지의 개발과 더불어 새로이 적용되고 있는 역구조 유기 태양전지에는 이 같은 친수성의 PEDOT:PSS 고분자가 소수성의 양극이나 광활성층 상에 균일하게 코팅되는 것이 문제점으로 지적되고 있다. 이러한 문제점을 극복하기 위해서 양극 버퍼층으로 $V_2O_5$와 같은 p-type 금속산화물을 사용한 연구가 많이 보고되고 있다. 본 연구에서는 저항을 낮추고 홀 이동도를 향상 시키기 위해 Ag를 삽입층으로 한 $V_2O_5$/Ag/ITO 구조의 다층 박막을 제작하고 Ag두께에 따른 전기적, 광학적, 구조적 특성의 변화에 대하여 살펴보았다. 가시광 영역에서는 Ag 두께가 증가함에 따라 광 투과율이 감소하는 반면 전기적 특성은 향상되는 것을 볼 수 있었다. 광소자의 투명전극산화물로 적합한 구조인지 평가하기 위해 Figure Of Merit(FOM)의 값을 측정하였고, 그 결과 Ag의 두께가 4 nm에서 가장 좋은 특성을 나타냈다. $V_2O_5$/Ag/ITO 구조의 다층 박막은 가시광 영역에서 Ag의 두께가 4 nm일 때 88%의 광 투과율을 나타내었고 저항 값은 $4{\times}10^{-4}{\Omega}cm$로써 광소자로 적합한 구조임을 확인하였다. Recently, the buffer layers consisting of poly (3,4-ethylenedioxythiophene): poly (styrenesulfonate) (PEDOT-PSS) are extensively used to improve power conversion efficiency (PCE) of organic solar cells. However, PEDOT-PSS is not suitable for mass production of organic solar cells due to its intrinsic acid and hygroscopic properties. Moreover, because of chemical reactions between indium tin oxide (ITO) layer and PEDOT-PSS layer, the interface is not stable. For these reasons, alternative materials such as $V_2O_5$ have been developed to be an effective buffer layer. In this work, we used $V_2O_5$/Ag/ITO multilayer structure for the anode buffer layer. With variation of thickness of Ag layer, we investigated the optical and electrical properties of $V_2O_5$/Ag/ITO multi-layer films. As a result, we found that the electrical properties were improved with increasing Ag thickness while optical transmittance decreases in visible wavelength region. From the calculation of figure of merit (FOM) which is used to evaluate proper structure for transparent of optoelectronic, $V_2O_5$/Ag/ITO multilayer electrode was optimized with 4 nm thick Ag layer in optical (88% in transmittance) and electrical ($4{\times}10^{-4}{\Omega}cm$) properties. This indicates that $V_2O_5$/Ag/ITO multilayer electrode could be a candidate for the anode of optoelectronic devices.

As the importance of intellectual property rights for the 21st century challenge became prominent, many companies have been trying to secure many rights competitively. In particular, application numbers of patent that represents technology has been increased continuously. Korean companies were not exception; mainly in large companies, there have been continued the efforts to grow the number of patent applications in quantitative volume. But the issues that how viable patents the companies have, how effectively the companies manage, and how economically usable the patents are, are totally different from quantitative management level. As such, the issue is connected to how to assess the patent management level of companies. On the other side of quantitative growth of patent that companies hold, there are some problems such as the difficulties to determine if the patents hold substantial values, and the difficulties to determine whether the patent are managed effectively. In addition, as the numbers of patent application and registration of companies are increased, the cost for patent holding and managing increase. It is required to pay continuous attention to the cost of patent management because patent registration fee has a property that increases rapidly with time and burden for patentee become heavier. As a result of analysis and interpretation, we confirmed that quantitative management, particularly the number of patent applicant does not make positive impact on how to use patent after application. Rather, it is observed that the economical usage is influenced positively by the efforts of patent applicants such as considering for the time of patent examination, paying attention to receive patent registration decision. Therefore, this study shows that efforts patent applicants provide in management level after application time are important to maintain the value of patents.

Each bank which enters the China market has its own reasons. But, in general, the main purposes are for market expansion to meet China's huge demand, for diversifying revenue structure with the yuan emerging as a key currency and for building business networks in China in view of its rapid rise as a G2 country. The importance of China' financial market while growing as a G2 country has therefore increased. Wooribank China has used diverse strategies, including strategic business alliances, to expand financial services in China and undertake plans to ensure its ongoing competitiveness. Strategies in China can be divided largely into four kinds: active network expansion, product and service differentiation, talent hunt and workforce localization and Contributions via CSR activities for the local community. The purpose of this study to clarify the characteristics and difference of Wooribank China which we rated as having the most aggressive localization strategy than those of Korean banks based on present conditions in China. We were able to verify that the fast execution of these strategies of Wooribank China formed the basis of its growth. Also, Korean banks which enter or have entered China need to carefully cope with the market and law trends. This is because even if they entered the Chinese market successfully, this may not be guaranteed in the future due to the number of expected challenges, both inside and outside the country. This suggests that continuous diagnosis of the bank's operating strategy for competing with local Chinese large banks and global banks must be done.

서울굿의 동쪽제와 서쪽제 비교

고영희(Ko Yeong-hee) 비교민속학회 2005 비교민속학 Vol.0 No.29

Seoul Gut has been handed down in different forms of shamanism according to locality. Dongjjokje and Seojjokje indicate shamanist sects handed down around the areas of Araedae and Udae. Dongjjokje and Seojjokje have not been covered much in previous researches, but phrases such as “West shaman and east shaman musician" or "East shaman and west shaman musician” suggests that the east and the west had been distinguished from each other. It was confirmed that Dongjjokje and Seojjokje were not academic terms but native words used naturally in shamanist performances in Seoul in the past. The present study made discussion, assuming such a difference in Seoul Gut among localities. However, shamanist performances in the present are quite different from those in the past. What matters with regard to Dongjjokje and Seojjokje is not the superiority of Dongjjokje or Seojjokje in value. This study discusses them in order to find the possibility that they can be appropriate standards for understanding continuously changing shamanist performances. In order to compare Dongjjokje and Seojjokje, this study summarized the patterns of various forms of Seoul Gut ‘shaman schools’ reported in previous researches and inquired into settled principles applied in dividing areas. In addition, it examined how ‘shaman schools’ have maintained their tradition through the history of instruction among shamans who have been main actors of transmission. What is more, this study reviewed the genealogy of shamans and compared Dongjjokje and Seojjokje in order to understand the pattern of the transmission of ‘shaman schools.’ In comparison between Dongjjokje and Seojjokje made through interviews with shamans, difference in order of <Bulsageori> and <Sangeori> was identified. Dongjjokje and Seojjokje are meaningful in that they attempted not only geographical decentralization but also decentralization according to cultural environment in those days.

서울지역 당신화 연구

고영희(ko young-hee) 한국무속학회 2006 한국무속학 Vol.0 No.11

당신화는 당신(堂神)에 대한 이야기이다. 당신화는 대개 당의 유래나 당신의 내력, 또는 당신의 영험함과 관련된 내용을 담고 있다. 이같은 구비 전승물은 당신이 지역민들에게 신앙의 대상으로 섬겨졌다는 사실이 간과된 채 단순한 유래담 정도로만 치부되기도 하였다. 하지만 최근에는 구비신화에 대한 논의가 활발하게 진행되면서 무속신화나 당신화 연구가 그 다양성이나 양적인 면에서 진일보했다고 보인다. 그럼에도 불구하고 서울 지역의 당신화에 대한 관심은 전무한 상태이다. 본고는 다른 지역에 비해 소홀하게 취급되었던 서울의 당신화를 논의의 대상으로 삼았다는데 일차적인 의의를 지닌다. 본고는 서울시 성동구 행당동에 위치한 아기씨당에서 전승되고 있는 당신화를 대상으로 한정하였다. 아기씨당은 달리 진퍼리 살군당이라고 불려지는데, 이 외에도 진퍼리 살군당 부인마마, 왕십리 애기씨당, 애기씨당(아기씨당) 등의 이칭(이칭)이 존재한다. 특히, 서울 지역 무가 사설에서도 당의 존재를 확인할 수 있는데, 이를 통해 서울 만신들에게 중요한 당으로 여겨졌던 것으로 보인다. 그리고 현재까지도 당의 전승이 온전하게 이루어지고 있으며, 당주의 계보가 확실하여 논의의 대상으로 삼는데 적합하다. 그리고 무엇보다도 아기씨당은 당신화의 주인공인 ‘아기씨’와 관련된 구비전승뿐만 아니라, 아기씨당굿의 의례를 통해 신성성을 공고하게 하고 있어 주목 본고는 아기씨당신화의 당신화의 성격, ‘아기씨’의 신격, 당굿에 대한 논의로 이루어졌다. 아기씨당신화는 주인공이 여성 원혼(?魂)인 당신화의 일반적인 문법을 따르고 있다. 당의 주신인 ‘아기씨’의 성격을 파악하기 위해 서울 지역 무가 사설에서 언급된 ‘당’의 신격과 비교하였다. 그 결과, 아기씨는 결혼하지 않은 고귀한 신분의 여성신격임을 파악할 수 있었다. 당신화는 일반 구비전승물과 달리 의례인 당굿과 밀접한 관련을 지니므로, 현장적 기능의 파악이 요구된다. 당신(堂神)인 ‘아기씨’는 마을의 주신(主神)으로 마을의 안녕을 기원하는 당굿에서 그 기능을 다하고 있음을 확인할 수 있다. Dang myths have been handed down through local residents’ religious beliefs and rituals. In the early period of myth research, Dang myths were regarded merely as folktales about the origin of Dangs or Dang deities. Recently, however, shamanic myths and Dang myths are incomparably dominating myths recorded in literature in diversity and volume. Nevertheless, there has been almost no research on Dang myths in the Seoul area. The significance of this research is found in fact that it discusses Dang myths in Seoul, which have been relatively neglected compared to those in other areas. In this research, our discussion was limited to Dang myths handed down with regard to Agissidang at Haengdang Haengdang Agissidang(행당동 아기씨당) was also called Jinpeori Salgundang(진퍼리 살군당) as well as Jinpeori Salgundang Buinmama(진퍼리 살군당 부인마마), Wangsimni Aegissidang(왕십리 아기씨당), and Aegissidang. The current Dang host and residents in the area called it ‘Aegissidang’ as confirmed in the field. Jinpeori Salgundang was selected as the main object of discussion because the tradition of the Dang had been transmitted wholly and the lineage of Dang hosts was clear, so we could get relatively accurate information. Limiting our discussion to the myth of Haengdang Agissidang, we examined relevant materials and found that the attitude of transmission was different according to transmitter. In order to examine the character of ‘Agissi,’ the main deity of the Dang, moreover, we compared it with the deity of ‘Dang’ mentioned in shamanic narrations in Seoul. Lastly, to discuss the correlation between Agissidang myth and Dang gut, we examined the function of Dang myths, oral heritages, in Dang gut and found that it composed a process of the ritual. The results of this discussion showed that Agissidang myth is not irrelevant to the characteristics of shamanisms in Seoul. However, because this study was focused on the discussion of Dang myths, we did not cover other heritages surrounding Agissidang. Further detailed and systematic discussion is necessary with regard to the structure of traditions surrounding the Dang. It is because the ritual where the myth is recited needs to be explained more thoroughly in consideration of geographical and cultural contexts.

Under the influence of growing popularity of “hallyu” (Korean wave), corporates that have copyrights such as music, movie, drama as their core competitiveness are showing continuing growth. In Addition, they built on contents are rapidly growing, interests in protection and management of intellectual property rights linked to contents are growing. Global contents development corporates are making great efforts to create profits out of copyrights. They could utilize original contents to strengthen brand value use it to produce additional contents in current market. Also they take advantage of existing storyline of the contents and strong brand to explore new markets. This paper looks into Value articulation model by Professor James Conley and analyzed the firms that utilized intellectual property rights to extend the period of protection, strengthen their competitiveness and succeeded in breaking into new market by using the rights they possess. Also, this paper examines the usage of intellectual property rights and business expansion strategy of < Pororo > of Iconix, the Korean entertainment company, which gained tremendous popularity in last ten years using this model. In Value articulation model, Conley classifies the process of exploiting the portfolio of the single product’s(or service’s) intellectual property right for a period of time into three stages ; value transference, value translation, value transportation. Pororo’s strategy of utilizing intellectual property right is suggestive to domestic entertainment companies. Under the influence of hallyu” (Korean wave), domestic contents such as movies, dramas and music are enjoying the high level of popularity recently not to mention animations. In reality, Korean entertainment companies who have no background or experience of Intellectual property rights are not creating enough added values compared to fast growing market. It is believed Iconix’s intellectual property rights management strategy will suggest positive aspects to domestic companies. Moreover, I hope various intellectual property rights management strategies including Conley’s value articulation are studied and they can make contributions to managing domestic entertainment companies

전통과 현대경영을 접목하고 있는62년 전통의 제주 향토기업, ㈜한라산소주

고영희(Young Hee Ko),조수민(Su Min Jo),허정옥(Jung Ok Hur) 한국경영학회 2014 Korea Business Review Vol.18 No.2

(주)한라산소주는 국내 주류 업계에서 유일하게 4대에 걸쳐 62년 동안 장인정신을 가지고 지속적으로 성장해 온 제주 지역 대표적인 향토기업이다. (주)한라산소주는 1976년부터 실시된 자도주 의무구입제도의 직접적인 혜택으로 약 20년간 안정된 경영을 할 수 있었다. 하지만 1996년 자도주의무구입제도의 폐지로 무한경쟁체제로 돌입하게 된 시장환경 속에서 3대 대표로 취임한 현승탁 회장은 한라산 소주를 출시한 데 이어 한라산 허벅술 등 신제품을 잇따라 출시하며 제품경쟁력을 높이기 위한 연구개발에 역량을 집중하였다. 그 결과 지난 2012년 국제주류품평회 시상식에서 우리나라 증류주 부문 최초로 한라산 허벅술이 금상을 받는 성과를 이루었다. 이러한 제품 경쟁우위는 끊임없는 신제품 연구를 가능하게 한 설비투자와 차별화된 팩키징 디자인을 통한 프리미엄 브랜드 제고 전략, 청정 제주 화산암반수를 사용하는 고품질 원료사용의 3가지 전략에 기인하고 있다. 그 결과 한라산소주는 지역 고용창출과 지역 경제에 일익을 담당하는 건실한 향토기업으로 성장하였다. 더불어 현승탁 회장은 제주 도민의 신뢰를 가장 소중한 자산으로 여기는 경영 이념을 가지고 다양한 지역사회 공헌활동을 지속적으로 유지해 왔다. 이러한 성장과정에서 장인정신에 기반한 전통과 현대경영 접목의 경영철학과 사람을 중시하는 기업문화 역시 경쟁력이 되어 왔다. 하지만 높은 물류비용이 발생하는 도서 지역의 한계와 경쟁이 심화되어 가는 경영 환경 속에 (주)한라산소주는 과거의 성공전략과는 또 다른 혁신적인 전략을 고안해 내고, 이를 효과적으로 추진해 나갈 것을 요구 받고 있다. Hallasan Soju, the representative local company of Jeju-do, has grown uniquely in the domestic liquor business over 4 generations. Hallasan Soju had received the benefit of system of obligation to purchase a soju at the local area and managed steadily for about 20 years thanks to that. But the purchase system was abolished in 1996 and since then on competition has become fierce in the Soju market. In that market situation president Hyeon seung-tak was appointed as the third CEO of Hallasan Soju and he concentrated the resources to the R&D to raise the product competitiveness. As a result, Hallasan Heobeoksul won the gold prize award in the spirituous liquor section in 2012 IWSC(International Wine and Spirit Competition), which is for the first time in Korea. These product competitive advantages are caused by three strategies like the facility investment, premium brand strategy and high quality use of the materials. Finally Hallasan Soju has grown as a sustainable company contributing to the local job creation and local economy. In addition, president Hyeon seung-tak has had the management principle that considers the faith of the region as the most valuable asset. So Hallasan Soju has maintained continuously the various contributory activity to local communities. In this growth process, the management philosophy combining tradition and modern management has been becoming the competitiveness. But because of the limited geographical situations as the islands region which the high logistic cost happens and the deepening competitive environment, now Hallasan Soju is asked to push ahead the past success strategy and another innovative strategy.
