Introduction: To analyze the impact of marketing losses on efficiency in transacting banana in Kurnool district of SRZ in Andhra Pradesh and to assess the opinions of the farmers on the constraints in transacting banana. Research back ground, Materials and Methods: The study relies exclusively on primary information obtained from the banana farmers of Kurnool District. Purposive sampling procedure was followed for the selection of the study area. Top two mandals in the district and top two villages in each mandal are selected in accordance with the area under cultivation of banana. Probability proportion to size was followed regarding the selection of sample farmers and accordingly 60 marginal, 37 small and 23 other farmers were selected and thereby, the total sample size was 120. Result and Discussion: Three marketing channels were identified in the marketing of banana in Kurnool district viz., Producer → Local-exporter → Wholesaler → Retailer → Consumer (Channel-I), Producer → Wholesaler → Cart-vendor → Consumer (Channel-II) and Producer → Juice-holder → Consumer (Channel-III). With the inclusion of marketing losses in the price spread analysis of banana in all the three channels, the marketing costs of all the intermediaries were increased and thereby, the farmer’s share in consumer’s rupee and Net Marketing Margins of the agencies are on the decline. So, without inclusion of marketing losses, the farmer’s share in consumer’s rupee and Net Marketing Margins of all the agencies are overvalued. The higher the marketing losses, the more is the negative impact on farmer’s net selling price, net marketing margins of the intermediaries and marketing efficiency. The sample farmers are facing major problems in marketing of banana like frequent price fluctuations, unorganized marketing and lack of transportation facilities on priority basis. Suggestions: It is suggested to educate the farmers regarding the optimum maturity index for harvest, use of mechanical harvesters, proper placement of fruits during storage and ripening, better packaging and cushioning technologies to absorb shocks during transportation, strengthening of storage facilities and transport facilities, encourage co-operative marketing etc., to promote marketing efficiency of banana in the study area.

The Korean aquaculture industry was generally began in the 1970s and has gradually increased. Now, the number of households is about 7,068 and the scale of an aquaculture farm is about 248,014 ha; the value of all production in the industry is estimated to be about 1602.2 billion won. The aquaculture industry is very valuable and important for future food resources. However, the aquaculture industry was damaged by several marine ecological disturbance causing organisms. The Ascdiella aspersa colonized on the shell of scallop and then scallops were detached from rope. The patterns of damage in the aquacultures were observed in Tongyeong (oyster), Geojedo (oyster), and Gangneung (sea squirt) in June, 2017, as well as in Tongyeong (oyster) in November, 2017 by SCUBA divers. The species Halichondria bowerbanki, Bugula neritina, Mytilus galloprovincialis, Balanus amphitrite, Ascidiella aspersa, Ciona intestinalis, Didemnum sp, Styela plicata in Tongyeong, M. galloprovincialis, A. aspersa, C. intestinalis, D. vexillum, S. plicata in Geojedo, and M. galloprovincialis in Gangneung were all usually found in their farms. The marine ecological disturbance causing organisms gave rise to a reduced number of aquaculture products.

This study evaluated the ecotoxicological properties of livestock waste water treated by a LID (Low Impact Development) system, using a mixture of bio-reeds and bio-ceramics as suitable bed media for a subsequent treatment process of a livestock wastewater treatment plant. The relationship between the pollutant reduction rate and the ecotoxicity was analyzed with the effluents from the inlet pilot plant, with vegetated swale and wetlands and the batch type of an infiltration trench. Each pilot plant consisted of a bio process using bio-reeds and bioceramics as bed media, as well as a general process using general reeds and a bed as a control group. The results indicated that, after applying the HRT 24 hour LID method, the ecotoxicity was considerably lowered and the batch type pilot plant was shown to be effective for toxicity reduction. The LID method is expected to be effective for water quality management, considering ecotoxicity by not only as a nonpoint source pollution abatement facility but also, as a subsequent treatment process linked with a livestock manure purification facility. It is necessary to take the LID technic optimization study further to apply it as a subsequent process for livestock wastewater treatment.

Entering the New-normal era, China has defined the start-up as a driving force for sustainable economic development. China's start-up support policy, represented by "makers", is now China's biggest issue. China has established a society based on makers and presented a new development model that enables socially diverse economic communities to continuously develop the Chinese economy. This paper intends to enhance the structural and in-depth understanding of “makers-based society” by analyzing the socially influential actors/keywords of China's makers policy. For this purpose, Big data related to makers were collected for data analysis and data mining and semantic network analysis were conducted. The results of the analysis are as follows: First, China's makers policies are steadily expanding and developing due to active government support and the enthusiasm of social entrepreneurship; Second, from the social point of view, the value of the start-up, the market orientation, and the regional support policy are important; Third, China has been actively developing and utilizing entrepreneurship-related curriculum, and it has been cultivating human resources suitable for start-up; Fourth, makers are an important platform for globalization of human resources in China as a driving force for sustainable development. It is also revealed that young people are building their own entrepreneurial ecosystem through their start-up and realizing their dreams.

Companies must capture value for sustainable growth. Capturing value is a critical task for companies, particularly when operating own businesses and organizations or starting new business. The business strategy of many companies focuses on capturing the maximum value from customers and other stakeholders. Even though a wide range of studies on value creation and appropriation has been conducted in the strategic management field, most of studies are still conceptual and theoretical. Thus more empirical studies are required to suggest future-oriented value strategy. This study reveals the value creation and appropriation elements in the aviation industry of Korea. The purpose of this study is to understand the trend of value creation and appropriation in the industry. In addition, the relationship between the elements and firm’s performance are tested. The firm’s performance is defined by that past and future point of views. The sample were collected from Korean Air and Asiana Air. The empirical test shows that the elements of value creation-appropriation have significant impact on firm’s performance. Further, the element of value appropriation to customer has a positive impact both on firm’s past and future performance. Our results show that investors acknowledge a value-based strategy as a sign of stock valuation. The results of this test correspond with the earlier one, showing that maximizing customers value rather than shareholder value does deliver impressive returns. The finding suggest that companies need to change their strategy to efficiently manage performance. With the test results, we propose a value-based strategy to maximize firm’s future financial and stock performance.

국내 원자력발전소의 사용후핵연료는 소내저장시설에 보관되어 있으나 저장시설의 용량 확장이 어려움이 있으며, 연구기관 의 연구로에서 발생하는 고준위 방사성폐기물도 자체 보관중이나 영구적으로 저장할 수 없다. 또한 원전의 해체 시에도 고 준위 방사성폐기물이 발생할 것으로 예상된다. 이에 따라, 본 연구에서는 현재 개발된 사용후핵연료 운반용기를 사용하여 고준위 방사성폐기물을 가상의 관리시설로 철도를 통하여 운반하는 경우에 대하여 작업자 및 운반경로 주변 일반인의 예상 피폭선량을 평가하였으며, 그 결과를 국내 법적기준치와 비교하였다. 또한, 고준위 방사성폐기물의 상하차 작업 시 작업자 와 운반용기 간 거리와 운반사고 시 방사성핵종의 누출율의 변화에 따른 피폭선량의 변화에 따른 피폭선량 추이와 운반에 사용되는 열차의 구성에 따른 운반작업자의 피폭선량 변화를 분석하였다. 본 연구에서 설정한 모든 조건에서의 예상피폭선 량은 국내 법적제한치 이하임을 확인하였다.

본 연구는 제품혁신에 초점을 맞추어 기술혁신이 기업의 수익과 재무안정성에 미치는 영향을 분석하고 기업의 지속성장을 위한 전략적 시사점을 도출하는 데 목적이 있다. 제품혁신은 신제품개발 및 도입으로 정의한다. 기업의 수익은 종업원 1인당 매출액과 매출액 증가율로 측정하고, 재무안정성은 자기자본대비 부채비율과 유동비율로 측정한다. 실증분석 은 제품혁신의 내생성을 고려하여 2단계 추정법을 사용하였고, 분석자료는 ｢인적자본기업패 널(HCCP)｣의 1차(2005년)～6차(2015년) 자료와 한국신용평가(주)의 기업재무자료를 병합한 자료이다. 분석결과에 의하면, 제품혁신은 기업의 지식자본스톡과 인적자원투자, 시장선도전 략 등에 영향을 받으며, 제품혁신이 활발히 이루어지는 기업일수록 1인당 매출액과 매출액 증가율이 높고 부채비율은 낮으며 유동비율이 높다. 이러한 분석결과는 기술혁신투자와 이 를 통한 제품혁신이 기업의 단기수익 창출 및 장기적인 재무안정성을 촉진하는 중요한 전략 이라는 것을 의미한다.

본 논문은 개인의 비합리적인 이타주의 행동을 설명하는 규범활성화모델을 활용하여 공정무역제품 구매행동을 촉진하는 개인적, 규범적, 문화적 요인을 통합적으로 다루고 있다. 모델 관련, 예기된 감정(예기된 자부심과 예기된 죄책감)과 두 가지 상충하는 개인가치(박애주의 가치와 권력 가치)를 공정무역 관련 개인규범 활성화 선행요인으 로 개념화 하였다. 그리고 활성화된 개인규범이 공정무역제품 구매행동에 영향을 주는 것으로 보았고 특히 이들 간의 관계를 문화 클러스터(유교, 라틴 유럽)가 조절하는 것으로 개념화 하였다. 구조방정식을 통해 얻은 실증결 과는 예기된 자부심이 개인규범에 미치는 영향력이 예기된 죄책감 보다 크고, 상충되는 두 가지 개인가치 중 이 타적 가치인 박애주의 가치만이 개인규범에 유의한 영향을 미치는 것으로 나타났다. 그리고 활성화된 개인규범은 공정무역제품구매 행동에 유의한 영향을 주는 것으로 조사되었다. 문화 클러스터의 조절효과는 다집단비교 구조 방정식을 통해 분석하였다. 검증결과, 해당 경로에 대한 영향력이 라틴 유럽 클러스터 보다 유교 클러스터에서 더 강한 것으로 나타났다. 이러한 결과는 유교 클러스터가 라틴 유럽 클러스터에 비해 직접적인 비용지불에 따른 자기희생 정도가 더 크고, 사회 구성원 기대에 상응하는 도의적 의무감을 강하게 느끼기 때문에 공정무역제품 구 매 행위가 더 강하게 나타난 것으로 해석 가능하다. 본 논문은 규범활성화모델을 활용하여 공정무역제품 구매행 동을 비교 문화적 관점에서 접근하여 윤리적 소비자의 의사결정과정을 실증적으로 구명했다는데 의의가 있다.

공정거래위원회는 2015년 기업메시징서비스 시장에서의 시장지배적 지위 남용에 관한 의결에서 관련 상품(서비스)시장의 범위를 ‘무선통신망을 통한 기업메시징서비스시장’으로 확정하였으나 이러한 판단은 더 이상 유효하지 않다. 스마트폰과 더불어 등장한, 한국 모바일메신저 앱 시장 의 94%를 점유하는 카카오톡이 기업메시징서비스 시장에서 변화를 일으키고 있기 때문이다. 카카오톡은 하이브리드 전송 서비스를 통해 무선통 신망을 보유하지 않고도 이를 보유한 이동통신사 업자들과 경쟁하고 있고 알림톡 서비스는 문자메 시지를 통한 기업메시징서비스보다 저렴하면서 정보 전달 기능 및 효용이 유사하여 이를 이용하는 업체의 수가 빠르게 증가하고 있다. 카카오톡은 이동통신사업자들의 무선통신망이라는 거대한 진입장벽을 이미 뛰어넘었으므로 당장 법원에 소송 계속 중인 사건에서 시정이 이루어지기는 어렵겠지만 향후 이러한 기술발전을 고려하여 기업메시징서비스 시장의 관련 상품시장 범위를 획정하는 법 집행 당국의 판단이 있어야 할 것이다. 기술의 발전이 법에 끼치는 영향에 적극적인 관심을 가짐으로써 새로운 법적 쟁점에 대응하는 자세가 중요한 이유이다.
