For earthquake loss estimation of building structures in Gangnam-Gu district in Seoul, three scenario earthquakes were selected by comparison of the response spectra of these scenario earthquakes with the design spectrum in Korean Building Code (KBC 2009), and then direct losses of the building structures in the Gangnam-Gu district under each scenario earthquake are estimated. The following conclusions are drawn from the results of damage and loss in the second scenario earthquake, which has a magnitude = 6.5 and epicentral distance =15 km: (1) The ratio of building stocks undergoing the extensive and complete damage level is 40.0% of the total. (2) The amount of direct economic losses appears approximately 19 trillion won, which is 1.2% of the national GDP of Korea. (3) About 25% of high-rise (over 10-story) RC building wall structures, were inflicted with the damage exceeding moderate level, when compared to 60% of low-rise building structures. (4) From the economical view point, the main loss, approximately 50%, was caused by the damage in the high-rise RC wall building structures.

수산양식어업은 수산생물질병을 어떻게 효과적으로 관리하느냐가 매우 중요하다. 이 논문은 경 제적 잉여분석을 이용하여 수산생물질병방역사업에 대한 경제적 편익의 직접적 효과를 추정하 는 것이다. 이와 같은 경제적 편익은 수산생물사망 감소율과 수산생물질병감소로 인해 발생하 는 소비자잉여와 생산자잉여의 변화 정도를 포함한다. 연구결과 양식되는 넙치, 볼락 및 기타 어류의 생산자잉여에 대한 연간 변화액은 총 23.3억원(각각의 경우 8.7억원, 10.1억원, 4.5억원) 이고, 소비자잉여의 연간 변화액은 총 101.5억원(각각의 경우 63.6억원, 18.5억원, 19.4억원)으로 추정되었다. 따라서, 수산생물질병방역사업에 따른 연간 총 경제적 편익은 125억원 수준으로 평가된다.

본 논문에서는 한국은행에서 발표한 4년(2010-2013) 동안의 산업연관표로부터 해양환경산업의 시장규모 및 부가가치액을 추계하여 국민경제적 지위를 따져보고, 산업연관분석을 적용하여 해양환경산업의 경제적 파급효과를 분석하였다. 해양환경산업의 시장규모를 추계한 결과, 총 산출액은 2010년 1조 3,406억원에서 2013년 1조 9,723억원으로 증가하였으며, 총 산출액 전체에서 차지하는 비중 또한 0.04%에서 0.05%로 증가하였다. 부가가치액은 2010년 6,185억원에서 2013년 8,415억원으로 증가하였으며, 국내총생산에서 해양환경산업의 부가가치가 차지하는 비중은 0.05%에서 0.06%로 증가하였다. 또한 수요유도형 모형을 이용하여 경제적 파급효과를 분석한 결과, 해양환경산업에서의 1원 생산 또는 투자가 국민경제 전체에 야기하는 생산유발효과는 2010년 1.8845원에서 2013년 1.8115원으로 소폭 감소하였다. 해양환경산업에서의 1원 생산 또는 투자로 발생하는 부가가치 유발효과는 2010년 0.7680원에서 2013년 0.7063원으로 감소하였다. 해양환경산업에서의 10억원 생산 또는 투자의 취업유발효과는 2010년 10.17명에서 2013년 9.18명으로 감소하였다. 요컨대, 해양환경산업의 산출액 및 부가가치는 증가 추세를 보이고 있지만, 경제적 파급효과의 원단위는 감소 추세를 보였다.

본 연구는‘부유’단감의 경제적 가치를 평가하기 위해 이루어졌다. 연구를 위해 최근 9년간의 단감 ‘부유’주산지 소득조사 원시자료(707농가)와 현장을 방문하여 조사한 47농가의 자료를 이용하여 kg 당 수취가격, 투입비용, 주당 수량을 분석하였다. 연구결과 단감‘부유’의 손익분기수령은 성장기 8수 령과 쇠퇴기 85수령으로 분석되어 단감‘부유’의 경제적 갱신 한계 수령은 85수령으로 나타났다. 주당 수량은 65수령을 전후로 가장 높은 것으로 나타났다. 경제적 내용연수 85수령을 기준으로 한 단감‘부 유’의 주당 경제적 가치는 수익접근법에 의해 10,488천원, 비용접근법에 의해 9,249천원으로 분석되었 다.

2012년 기준 산촌지역 임가소득은 도시근로자의 54.3%, 농가의 67.6%에 불과하며, 노동집약적인 1차 산업 위주의 임업은 부가가치 창출에 한계를 갖고 있다. 한편 우리사회는 여가시간 증가, 삶의 질을 강 조하는 생활 방식이 자리하게 되면서 도시에서 벗어나 산림에서 체험하고 힐링을 하기 위한 수요가 지 속적으로 증가하고 있다. 따라서 산림수요에 대응하여 기존에 1차 산업 위주의 임업 외에 부가가치를 증대시킬 수 있도록 종합적인 정책마련이 필요하다. 이를 위한 하나의 방안으로 산림치유를 활용한 사 업이 전개되고 있다. 이에 본 연구에서는 산림치유를 이용한 산촌지역 경제 활성화 방안을 모색하고자 산촌지역에서 행해지는 산림치유시설의 특징, 프로그램 내용 등을 인터넷 조사와 현지 방문, 전문가 인 터뷰를 수행하였다. 이후 인터뷰한 원자료를 Strauss & Corbin(1998)의 근거이론방법을 적용하였으며 NVivo11 프로그램을 활용하여 총 186개의 개념과 8개의 범주와 24개의 하위범주를 도출하였고, 산촌지 역 경제 활성화를 위한 산림치유 적용 과정을 제시하였다. 본 연구는 산촌지역에 산림치유 적용방안을 위한 정책 제언을 제시함으로써 향후 정량적 연구의 토대를 마련했다고 할 수 있으며, 산림치유마을 조 성·운영정책을 추진할 수 있는 기초자료를 제공했다는 점에서 연구의 의의가 있다.

PURPOSES : Long-life asphalt pavements are used widely in developed countries. In order to be able to devise an effective maintenance strategy for such pavements, in this study, we evaluated the performance of the long-life asphalt pavements constructed along the national highways in South Korea. Further, an economic evaluation of the long-life asphalt pavements was performed based on a life-cycle cost analysis. We aimed to devise a model for evaluating the performance of long-life asphalt pavements using the national highway pavement management system (PMS) database as well as for analyzing the economic feasibility of such pavements, in order to promote their use in South Korea. METHODS : The maintenance history and pavement performance data were obtained from the national highway PMS database. The pavement performances for a total of 292 sections of 10 lanes (5 northbound lanes and 5 eastbound lanes) of national highways were used in this study. Models to predict the performances of hot mix asphalt (HMA) and long-life asphalt pavements under two distinct traffic conditions were developed using a simple regression method. Further, the economic feasibility of long-life asphalt pavements was evaluated using the Korea Pavement Management System (KoPMS). RESULTS : We developed service-life prediction models based on the traffic volume and the equivalent of single-axle load and found that long-life asphalt pavements have service lives 50% longer than those of HMA pavements. Further, the results of the economic analysis showed that long-life asphalt pavements are superior in terms of various economic indexes, including user cost, delay cost, total cost, and user benefits, even though their maintenance cost is higher than that of HMA pavements. A comparison of the economic feasibilities of the various groups showed that group A is superior to HMA pavements in all aspects except in terms of the maintenance criterion (crack 20% or higher) as per the NPV index. However, the long-life asphalt pavements in group B were superior in terms of the maintenance criterion (crack 25% or higher) regardless of the economic feasibility. CONCLUSIONS: The service life of long-life asphalt pavements was found to be approximately 50% longer than that of HMA pavements, regardless of the traffic volume characteristics. The economic feasibility of long-life asphalt pavements was evaluated based on the KoPMS. The results of the economic analysis were the following: long-life asphalt pavements are exceptional in terms of almost all factors, such as user cost, delay cost, total cost, and user benefit; however, the exception is the maintenance cost. Further, the economic feasibility of the long-life asphalt pavements in group B was found to be better than that of the HMA pavements (crack 25% or higher).

This paper aims to contribute to the developing literature of brand attachment and detachment theory, in the context of harsh economic conditions. The Cognitive Appraisal Theory and the Attachment Theory are brought to bear in order to describe and explain consumer shifting patronage decisions.

Introduction The research described in this abstract discusses “multilevel marketing,” including a review of academic literatures and studies that have used the direct sales business method as a research context. The multilevel marketing business structure represents an alternative to the business-employee-consumer relationships of those offered by traditional bureaucratic organizations. As such, they have, on one hand, collectively prospered and, on the other hand, attracted negative attention from regulatory and government entities, scholars, and competitors. Studies related to MLM organizations have examined these businesses on every populated continent, and have considered the viewpoints of consumers, MLM participants, and sales managers. Research has included a variety of empirical approaches, from quantitative survey methods to qualitative ethnographic studies. Consumer dispositions toward MLM have been measured intermittently over several years, and include consumer responses from many different countries. One consistent finding is that people who have purchased products from MLMs expressed more favorable opinions of them than do those who have not bought from MLM. Further, studies also provide evidence that consumers perceive that buying from direct selling is perceived to be less risky than some other non-store shopping modes (Gillett, 1976; Peterson, Albaum & Ridgway 1989; Alturas, Santos & Pereira 2005). Nonetheless, the practice is controversial and faces intense scrutiny in many countries while being banned in others. However, the research literature suggests careful consideration of the benefits of MLM organizations, in that the nontraditional organizational structure and methods of promotion may provide economic development in poor economies and also allow consumer-participants to develop important skills. One common method of retailing is direct sales. Direct selling companies emphasize promotion and distribution of their products through person-to-person contact, usually away from a physical retail location and usually through some network of independent sellers. The sales presentations are often held in homes, in the form of door-to-door solicitation, one-to-one meetings, through sales “parties,” or through some type of online social media platform (e.g., Facebook). Direct selling provides a channel of distribution for companies as an alternative to traditional retail outlets; it is attractive to companies that may be unable to compete with the vast advertising and promotion expenses that other manufacturers employ to gain shelf space in traditional retail stores. The variety of products and services that are sold through direct sales matches that of major traditional retailers, including cosmetics, home décor, wellness, jewelry, kitchen products, clothing, organic gardening, and scrapbooking supplies. Promotion of the products often relies on product demonstrations. One type of direct sales is multilevel marketing. A multilevel marketing organization (MLM) is a type of compensation structure (Coughlan & Grayson 1998) through which distributors earn income from their own sales as well as through commissions from the sales made by individuals they have recruited into their organization. As depicted in Figure 1, there are three basic components to compensation: 1. Distributors purchase the products or services at wholesale cost from the MLM organization; these products are sold at a profit (markup) to end consumers 2. Distributors are paid a commission by the MLM for what they sell directly 3. Distributors earn a bonus (percentage) of the sales made by individuals they recruit into the MLM. Recruits are referred to as the distributor’s “downline,” while the recruiter is referred to as the recruited person’s “upline.” MLM and traditional organizations MLM participants include people with diverse backgrounds, levels of education and experience, and personal qualities. Direct selling organizations rely on social connections and relationships to broaden their potential customer base; MLM organizations rely on these social connections as integral to their recruiting as well. MLM organizations do not have formal sales management structures. MLM participants are not “employees,” but rather act as independent franchisees that must adhere to organizational, ethical, and legal parameters. MLM participants are usually not co-located – they do not work at a central office – and often begin work part-time. Participants usually pay start-up or membership fees and pay for training and other selling-related materials. Because MLMs operate without bureaucratic organizational structure or traditional workplace, the company’s culture and ideologies are circulated through social relationships of each individual participant. Several researchers have asserted that cultural characteristics have a significant impact on the success of MLMs in any economy. Biggart (1989) observed that MLMs are successful in Asian countries because those societies tend to be very structured and hierarchical, and individuals in those countries carry a Confucian work ethic similar to Protestant ethic characteristic of the United States. Additionally, Asian extended family networks make selling and recruiting easier. By contrast, Herbig and Yelkurm (1997) observed that MLMs have not succeeded in parts of Europe, because the cultural and ideological climate is comparatively unreceptive to free enterprise and market entry. Laws restrict sellers to contact people at home. Southern European countries, however, tend to have larger informal sectors, fewer worker protections and restrictions, and stronger family and extended-family relationships. Statistics Worldwide, direct retail sales were $182.8 billion in 2014, an increase of over 6% from the previous year; these sales were generated by over 99 million direct-sellingretailers, including cosmetics, home décor, wellness, jewelry, kitchen products, clothing, organic gardening, and scrapbooking supplies. Promotion of the products often relies on product demonstrations. One type of direct sales is multilevel marketing.

Southern European countries, however, tend to have larger informal sectors, fewer worker protections and restrictions, and stronger family and extended-family relationships. Statistics Worldwide, direct retail sales were $182.8 billion in 2014, an increase of over 6% from the previous year; these sales were generated by over 99 million direct-selling distributors (World Federation of Direct Selling Associations, 2015). The primary product categories included cosmetics/personal care, wellness, household products, and clothing/accessories. The largest markets for direct selling include the United States, Europe, and Japan. The European Direct Selling Association (Seldia) reported that 2014 sales of direct selling firms in European Union countries were €24 billion (about $26.7 billion), with over 5 million direct sellers (Seldia, 2015). In Japan, 2012 direct selling revenues were ¥177 trillion ($16 billion), with 3.3 million participants (WFDSA, 2015). In the United States, there were over 18 million direct-selling distributors in 2014 who generated $34.5 billion, a 5.5% increase from 2013. The Direct Sales Association reported that over 95% of U.S. direct sales in 2011 were through MLMs (Direct Sales Association, 2015). In terms of participation, the vast majority of direct distributors are women in both of two largest aggregate direct-selling markets. In the European Union, 79% of all direct sellers were women in 2014 (Seldia, 2015); seventy-six percent of direct sellers were considered to be part-time. In the U.S., the percentage of female direct sellers in the U.S. in 2014 was 74% (DSA, 2015). Criticism and Legal/Regulatory Issues Legitimate MLMs are often characterized as or confused with illegal “pyramid” or “Ponzi” schemes, and seem to have always attracted regulatory scrutiny (Arun, 2015; Alpert, 2012; Croft, Cutts & Mould, 2000; Hyman, 2008; Herbig & Yelkurm, 1997; O’Regan, 2015). In response to illegitimate operations, consumer protection groups and federal and local governments have provided information and enacted laws which distinguish MLMs from their fraudulent counterparts. MLMs and pyramid schemes Much of the academic and legal literatures have ventured to provide formal delineation between legal MLMs and the illegal and unethical practices related to pyramid schemes (Stockstill, 1985; Coughlan & Grayson, 1998; Epstein, 2010; Vander Nat & Keep, 2002). There is nearly universal concurrence that whether a program is a legitimate multilevel marketing plan or an illegal pyramid depends on: (1) the method by which the products or services are sold; and (2) the manner in which participants are compensated. Basically, if an organization pays participants for sales by their “enrollees,” “recruits,” and/or their downline enrollees and recruits, that plan is multilevel. If a program compensates participants, directly or indirectly, merely for the introduction or enrollment of other participants into the program, unrelated to the sales of any product, it is considered to be a pyramid. In the United States, federal and state anti-pyramid statutes comprise a comprehensive consumer protection umbrella. These laws are designed to protect individuals from being defrauded through illegitimate programs which lure participants with the promise of easy money by compensating them from the investments of additional participants rather than from legitimate product sales. Federal and state regulatory agencies have sought to prohibit such illegal activity using laws that control pyramids, mail fraud, business opportunity, franchise, lottery, and securities. Internationally, many countries ban some forms of pyramid schemes. Pyramid selling and multilevel marketing both take the form of complex organizations, and because of different interpretations of business activities and underlying regulatory philosophies across countries, regulation takes different forms (Micklitz, Monazzahian & Rößler, 1999; Dobson, 2011; Chan, 1999; China Daily, 2013; Epstein, 2010). Economic Development and MLM Organizations Several studies have observed that one of the key reasons for the establishment and growth of MLM organizations has been that they are often introduced into a larger socioeconomic context, using pre-existing social relationships to become engrained in the overall complex of an economy. Indeed, in communities where families and social networks are relatively large and geographically concentrated, MLM organizations have tended to thrive. MLMs are particularly attractive employment options for groups of people who may experience high unemployment and discrimination in the primary labor market (Brodie, Stanworth & Wotruba, 1998), for example women (Biggart, 1989; Casanova, 2011a, 2011b; Vincent, 2003; Dolan & Scott, 2009; Cahn, 2011; Singh & Aggarwal, 2012) and ethnic minorities (Dai, Wang & Teo, 2011; de Vidas, 2008). Further, as many countries attempt to follow a neo-liberalized, free-market approach to economic development, employment has become more feminized (Standing, 1999) and selling for a transnational direct sales organization is often an appealing option for women in developing countries, providing paid employment that takes place not only outside the home, but outside the archetypical, standardized workplace of the export-product manufacturing factory (Casanova, 2011a, 2011b; Wilson, 1998). Other evidence has suggested several macro-environmental developments that continue to have an impact on direct sales organizations (Ingram, 1993; Ragland, 2012). First, the splintering of market segments into subsegments has compelled companies with fewer resources to focus to avoid the “mass market,” and focus instead on smaller segments, tailoring their efforts to gain customer satisfaction (Kotler & Armstrong, 2014). MLMs are particularly suited to this consumer environment – distributors talking directly to consumers to find out what it is that they want, like, and prefer. One further outcome of this fragmentation has been that people have been forced to seek new groups to satisfy their need to belong, and “hybrid” economic social networks such as MLMs satisfy these nonmaterial needs of distributor participants (Green & D’aiuto, 1977). This appears to be a reasonable explanation of why many of the largest MLM organizations have several million distributors, the majority of whom gain only very minimal financial rewards despite devoting a substantial portion of their time to company activities. A second macro trend is that of globalization. Over the past thirty years, a strong demand has developed for Western products in then-newly-opened European and Asian markets. This continues to be the case in central Asia (India, Russia) and Latin America. In addition to consumer demand, a high level of salesperson motivation in those countries cited as a key to success. Thus consumer demand for MLM-supplied products has grown, while the entrepreneurial spirit that multilevel marketing encourages is appealing to many who seek self-managed work and independence from the traditional employer-employee relationship. Third, manufacturers often pursue multiple channels of distribution to make products available, and MLMs offer a realistic (and often creative) alternative component. This makes it easy for shoppers to find what they want, and a “direct” channel can coexist with traditional channels, allowing entry into extremely local markets and extremely poor consumers (Ireland, 2008; Dolan & Scott, 2009). For example, Ireland (2008) provided several examples of the implementation of MLM in poor communities in South America. This strategy was executed by well-known brands, some of which were recognizable MLMs (e.g. Avon) and some of which were traditional consumer products manufacturers (e.g. Coca Cola). The MLM organization in each of these cases emphasized physical distribution – in some situations going so far as to provide refrigerators in the homes of poor consumers, who would then sell beer or soft drinks directly from their homes. Improving access to products involved elaborate multilevel marketing channels that used the social skills and energy of “bottom of pyramid” (very poor) residents who participated as distributors. A fourth macro-level trend has been that toward trust-based relationship marketing, defined as building, developing and maintaining strong relationships with customers and other stakeholders in order to obtain a high profitability through customer satisfaction (Berry, 1983). The success of the MLM business model as a strategic alternative may thus be linked to the macro-level processes in national and global economies. Discussion and Conclusions Modern versions of direct selling hold the potential to improve lives across the world’s developing economies as the range of products begins to include those that have high social value, such as medicines, hygienic items and communications. Multilevel marketing is an innovation that has become increasingly successful as it has evolved in Western economies to include well-known consumer products (Amway, Tupperware, Mary Kay) but also high-end fashion (J. Hilburn, Etcetera) and even sex toys (Passion Parties). In developing countries, the MLM represents a potentially lucrative channel for traditional companies seeking growth – the flexibility of the channel of distribution, the fact that it relies on existing relationships among potential consumers and distributors, and its ability to reach consumers directly make it a potential tool for economic development. Even still, multilevel marketing carries negative connotations in many marketplaces worldwide. Because MLM participants are technically not employees of their company, “control” over participants is difficult, and continued participation is difficult to maintain. The high degree of commitment and strong organizational culture seem to foster accusations of “cult” behaviors. While there is no question that false product or business opportunity claims may be made – as with any consumer product – academic research tends to suggest that prohibition or strict regulation needs to be carefully weighed against the potential benefits of MLM organizational structures and operations. Multilevel marketing and other direct sales channels of distribution may facilitate economic development, first by employing people who may have little business experience, and second by making products available to consumers in markets where few other retailers may be able to reach. Research also suggests that the MLM business method provides a legitimate alternative strategy to traditional retailing: marketers can get information to consumers in ways that are not feasible using traditional advertising or retail distribution, and person-to-person selling increases the likelihood of customer satisfaction.

This paper aims to illuminate the relationship between economic recessions and advertising messages. A content analysis of 1720 television commercials indicated that during the severe economic recession in Greece, advertisers communicated more rational appeals and placed emphasis on creative devices that enhance understanding, learning and recall of message content.

The KLF(Kruppel-like factors) are transcriptional regulators that including the C2H2 zinc-finger motif and regulation of cell growth, cell differentiation, and development. In this study, mRNA and total DNA was extracted from the meat around the backbone of 130 cattle that has economic traits score. The KLF11 gene was act on the center of the main pathway in associated with the development and growth of cells and the fat metabolism. Genetic polymorphism was detected by DNA sequencing. A total of four SNPs(G9047A, C9104G, G9131A, C9170T) were identified in exon 4 regions, statistical association analysis revealed that the G9131A polymorphism were significantly associated with marbling score. The real time quantitative PCR to investigated gene and miRNA expression patterns and identify the relation of economic trait in Korean Native Beef Cattle. Gene expression level linked to KLF11 genes was investigated by determining its association and variation with the economic traits in Korean Native Beef Cattle. The increment of KLF11 gene expresstion level is resulted in increasing marbling score(MS). We found that expression profile of KLF gene and mir-494 was contrast tendency because the lower expression ratio of gene was the higher marbling score rating was when we analyzed expression profile ofKLF gene and mir-494. Therefore, this result has useful in improvement of livestock in Korean cattle.

Consequently, boat fishing experience marine tourism activity has a very large economic value in Jeju Island.

As a macroscopic research for the economic system in MMORPG’s, I have analyzed the differentiation & characteristic of each economic system such as Picking Economy, Laissez-faire, Revised Capitalism, Neo-liberalism as well as Economic Democracy which is shown on online game. The picking economy of online game, like as Ultima Online, has the characteristic of co-work & co-distribution but the capitalist who has accumulated wealth appeared on Laissez-faire period. When the economic system of Laissez-faire has fell down, Revised Capitalism that includes the characteristics of government intervention has appeared. Finally, ArcheAge and MapleStory 2, which are represent for Neo-liberalism and economic democracy, are characterized by recovery of market functions & welfare.

The ANK1 (Ankyrin-1) gene, located on the bovine chromosome 27, encodes a structural protein which forms an important component of the cytoskeleton. Ankyrin belongs to a protein family that links membrane proteins to the underlying spectrin-actin cytoskeleton. Many studies on gene expression regulation have revealed that RNA polymerase binds to the ANK1 gene promoter region. The purpose of the present study was to investigate the relationship between the SNP of the ANK1 promoter region and economic traits in Hanwoo cattle. A total of seven SNPs (C-944T, C-733T, C-687G, A-672G, C-307T, A-104G, C-24T), found in 119 animals, were correlated to economic traits. One of these SNPs, A-104G, was reported for the first time in the present study. Three newly discovered haplotypes were not associated with economic traits. Significant (p<0.05) relationships were found between C-944T and carcass weight, backfat thickeness, loin muscle area and between C-733T, A-672G and intramuscular fat. These results suggest that the SNPs of ANK1 gene may be useful molecular markers for selection of meat yield and quality traits in Hanwoo
