  • Purpose: While prior research has identified ethical issues in marketing research, more research needs to identify specific ethical behaviors that marketing researchers should adopt. This research addresses this gap by identifying a few ethical behaviors that marketing researchers should consider. Research design, data and methodology: The present study has a justification to collect adequate textual data in the current literature using screening process based on the marketing ethics topics and themes, and ethical behaviors of marketing researchers. Results: Based on the literature analysis, a marketing ethics model, which included the principles of fairness, honesty, responsibility, and respect for stakeholders. Since the rise of e-commerce and technology, a growing demand for a method to analyze website user behavior has been growing. Researchers in the field of marketing are responding to this demand by creating innovative interactive platforms. Conclusions: The term "ethical practices in market research" refers to a collection of best practices that, when followed, increase the likelihood that the research carries out is ethical, fair, and accurate. Because there needs to be more theoretical work done on the topic, there should be more empirical studies on ethical behaviors in marketing research.

  • 생산자에게는 상품의 적정가격 보장과 생산의 극대화를 위한 시설 개선으로 소비자의 구매 욕구를 충족시키는 것이다. 막걸리의 유통 개선 방안을 논의하고 막걸리에 대한 이론과 막걸리 열풍의 사회적 배경 및 영향, 그리고 막걸리 유통구조의 개선 및 대기업의 진입으로써 막걸리 업계에 미치는 영향, 지속적인 시장 활성화 방안에 대해 분석했다. 막걸리 유통구조와 문제점은 현재까지 많은 문제점과 개선방안이 실재하였음에도 불구하고, 개선책이 마련되지 않은 이유는 소비자에 대한 부정확한 문제 인식이 주요원인이며, 막걸리 유통구조 개선의 궁극적인 목적은 생산자에게는 막걸리 시장의 활성화로 인한 생산 시설의 개선이며, 소비자에게는 적정한 가격에 안전하고 좋은 품질의 상품을 공급받는 것이다. 위에서 언급한 바와 같이 물류시스템의 개선과 위생안전 관리를 위한 정부의 지원 등을 통한 변화가 필요하며, 이에 따르는 많은 막걸리 업체들이 유통의 주요 문제로 인식하여야 할 것이다.

  • DQDB(Distributed Queue Dual Bus) protocol, the IEEE 802.6 standard protocol for metropolitan area networks, does not fully take advantage of the capabilities of dual bus architecture. Although fairness in bandwidth distribution among nodes is improved when using so called the bandwidth balancing mechanism, the protocol requires a considerable amount of time to adjust to changes in the network load. Additionally, the bandwidth balancing mechanism leaves a portion of the available bandwidth unused. In a high-speed backbone network, each node may act as a bridge/ router which connects several LANs as well as hosts. However, Because the existence of high speed LANs becomes commonplace, the congestionmay occur on a node because of the limitation on access rate to the backbone network and on available buffer spaces. to release the congestion, it is desirable to install some congestion control algorithm in the node. In this paper, we propose an efficient congestion control mechanism and fair and waster-free MAC protocol for dual bus network. In this protocol, all the buffers in the network can be shared in such a way that the transmission rate of each node can be set proportional to its load. In other words, a heavily loaded node obtains a larger bandwidth to send the sements so tht the congestion can be avoided while the uncongested nodes slow down their transmission rate and store the incoming segments into thier buffers. this implies that the buffers on the network can be shared dynamically. Simulation results show that the proposed probotol significantly reduces the segment queueing delay of a heavily loaded node and segment loss rate when compared with original DQDB. And it enables an attractive high throughput in the backbone network. Because in the proposed protocol, each node does not send a requet by the segment but send a request one time in the meaning of having segments, the frequency of sending requests is very low in the proposed protocol. so the proposed protocol signigificantly reduces the segment queuing dely. and In the proposed protocol, each node uses bandwidth in proportion to its load. so In case of limitation of available buffer spaces, the proposed protocol reduces segment loss rate of a heavily loaded node. Bandwidth balancing DQDB requires the wastage of bandwidth to be fair bandwidth allocation. But the proposed DQDB MAC protocol enables fair bandwidth without wasting bandwidth by using bandwidth one after another among active nodes.

  • Appropriate amount of water supply to paddy fields in proper time is important to achieve efficient agricultural water management. The purpose of this study is to evaluate the irrigation water supply adequacy for paddy fields using water level data in irrigation canals. For the evaluation, the real-time water level data were collected from main canals in the Dongjin irrigation district for 2 years. Using the water level data, delivered irrigation water amounts at the distribution points of each canal were calculated. The water balance model for paddy field was designed considering intermittent irrigation and the irrigation water requirement was estimated. Irrigation water supply adequacy was analyzed from main canals to the irrigation blocks based on the comparison between estimated requirement and delivered irrigation water amounts. From the adequacy analysis, irrigation water supply showed poor management condition in 2012 with low efficiency except the Daepyong canal section, and the adequacy in 2013 was good or fair except the Yongsung canal section. When irrigation water for paddy fields was insufficient, water supply adequacy was affected by irrigation area, but when irrigation water was enough to supply, adequacy was affected by distance from main canal to distribution points. These results of the spatial and temporal dimensions of the irrigation adequacy could be utilized for efficient irrigation water management to improve the temporal uniformity and equity in the water distribution for paddy fields.

  • Next Generation Beyond 4G/5G systems will rely on the deployment of small cells over conventional macrocells for achieving high spectral efficiency and improved coverage performance, especially for indoor and hotspot environments. In such heterogeneous networks, the expected performance gains can only be derived with the use of efficient interference coordination schemes, such as Fractional Frequency Reuse (FFR), which is very attractive for its simplicity and effectiveness. In this work, femtocells are deployed according to a spatial Poisson Point Process (PPP) over hexagonally shaped, 6-sector macro base stations (MeNBs) in an uncoordinated manner, operating in hybrid mode. A newly introduced intermediary region prevents cross-tier, cross-boundary interference and improves user equipment (UE) performance at the boundary of cell center and cell edge. With tools of stochastic geometry, an analytical framework for the signal-to-interference-plus-noise-ratio (SINR) distribution is developed to evaluate the performance of all UEs in different spatial locations, with consideration to both co-tier and cross-tier interference. Using the SINR distribution framework, average network throughput per tier is derived together with a newly proposed harmonic mean, which ensures fairness in resource allocation amongst all UEs. Finally, the FFR network parameters are optimized for maximizing average network throughput, and the harmonic mean using a fair resource assignment constraint. Numerical results verify the proposed analytical framework, and provide insights into design trade-offs between maximizing throughput and user fairness by appropriately adjusting the spatial partitioning thresholds, the spectrum allocation factor, and the femtocell density.

  • 국가차원의 신 재생에너지 활성화 방안에 따라 풍력발전 등의 대규모 분산전원 단지의 도입이 이루어지고 있으나, 이에 대한 기술적인 평가방안이나 해석 방법이 구체적으로 제시되어 있지 않아, 설치자(시도 및 지자체)와 운용자(한전의 배전지사/지점)들은 많은 혼돈과 어려움을 겪고 있는 실정이다. 따라서 본 논문에서는 태양광, 풍력 등의 분산전원이 배전계통에 도입되는 경우, 계통 연계에 대한 기술적인 적합여부를 종합적으로 평가하는 시스템을 개발하였다. 즉, 분산전원을 제작하거나 시공하는 업체와 일반 운용자나 사용자(분산전원을 잘 모르는 비전문가 포함)들이 손쉽게 접근하여, 분산전원의 연계시의 기술적인 문제점과 적합 여부를 판단하는 기술지원 평가 S/W를 제작하였다. 주요 평가 기능으로서는 분산전원의 계통연계 시에 발생할 수 있는 정상, 비정상(사고), 전력품질에 대한 항목으로서, 누구나 동일한 결과를 얻을 수 있는 표준계통에 근거한 평가 알고리즘에 의하여 연계 적합 여부를 판단하는 것이다.

  • 본 논문은 표준 DQDB에서 문제가 되고 있는 불공정성 문제를 경감한 새로운 MAC프로토콜을 제안하고 분석하였다. DQDB MAC프로토콜은 처리율, 메시지 지연 등에서 불공정한 면이 있으며, 대역폭은 슬롯재사용 혹은 파일의 긴 전송 동안 더욱 불균등하게 배분될 수 있다. 본 연구에서 제안한 새로운 프로토콜을 평형(Balanced) DQDB 프로토콜이라 부르기도 하며, 이 새로운 엑세스 프로토콜은 이중 비스 네트워크 프로토콜의 한 비트를 이용하여 대역폭 분할에 공정성 보장 및 DQDB의 모든 특징을 유지한다. 또한, 슬로의 순차적 균등 배분을 해석하기 위하여 Wen Jing 등이 제시한 DQDB분석 모델을 고려하였다. 즉 한 버스상에서 비지 비트의 발생 확률을 예측하고, 마코프 체인을 사용하여 제안한 프로토콜에서의 처리율과 전송 확율에 대하겨 연구하였다. 그리고 시뮬레이션을 통하여 각 노드에서 RQ나 CD계수기가 동적으로 변화하는 상태에서 평형 DQDB와 표준 DQDB, BWB 구조를 비교하였다. 그 결과, 평형 DQDB가 동상위 노드에서에서 처리율이 감소하지만, 전체 노드의 약 70~80% 정도가 처리율 0.9 이상으로 나타났으며, 이러한 특징들은 수치적 분석 모델과 유사한 결과를 나타냄을 확인하였다.

  • Purpose - The purpose of the study is to reexamine the price fairness as practiced by low cost airlines, as a consumer has to experience such inconveniences as inferior airport transportation, extra fees on in-flight meals, and non-negotiable seats, and consumers evaluate such experiences keeping in mind their total costs. This evaluation includes price fairness and allows a reasonable and overall consideration of factors of low cost airlines. It tries to set up a measurement of the indicators consumers' perceptions of price fairness academically as it adapts price fairness to airline services which are renowned for price volatility. Research design, data, and methodology - The research proposes an alternative pricing strategy for the long term profit of low cost airlines after going over conflicts between the traditional theory of consumers' price perception mechanism and flexible fair policy of low cost airlines. It was meaningful when it relates to the early stage of the business, while it enhances the risks relating to the long term survival of low cost airlines. In addition, it is significant as it highlights the negative influences on consumers' perceptions of price fairness, as low cost airlines run on extremely low cost perspectives. Results - The results of the research provide insight into four perspectives, as consumers' perceptions of price fairness are influenced by the frequency and range of price changes and services. The first perspective is that it would lead to positive price evaluation when a low cost airline cuts prices frequently with little changes than one big change. It also would lead to the same result when it comes to necessary services. The second perspective is that one big increase of price would rather undermine the negative aspects of price changes than those of several smaller ones. The third perspective is that additional services would be good to consumers' perceptions of price fairness as compared to discount benefits with respect to the cost. Finally, a low cost airline should consider that consumers will change airlines or defer their flight schedule if the flight fares increase beyond their limits. Conclusions - Low cost airlines should reconsider their pricing policies for services that were provided free earlier. A consumer would not like discount benefits when made to pay for services that were, for long, free of charge. If a low cost airline can provide services with no charge, it should improve volumes if the costs are standardized and, moreover, should consider the charging fees. Alternatively, a consumer can choose between services and fair discount. Low cost airlines are implementing sales promotion strategies, as the competition is more intense than it used to be. In these days, they should regard services over sales promotion, as consumers may prefer to spend money on good premium services. Some differentiation in services could create a good market position for the airlines and, hence, good financial performance.
