IEEE 802.11은 무선 네트워크에서 주된 기술로 자리를 잡고있다. 하지만 공평성 문제가 에드 �N 네트워크 상에서 발생한다. 두 개의 독립적인 송신 노드들이 매체를 독점하여 사용함으로써 중간의 다른 노드가 패킷을 전송하는 것을 막는 현상까지 발생한다. 본 논문에서는 (m,k)-firm 기법을 사용하여 T-MAC에서 발생할 수 있는 불공정 대역폭 분배 문제를 해결하였다. 즉, k 번 시도 중에 연속적으로 m 번의 매체 접근 기회를 가지지 못한 노드에게 제일 높은 우선순위를 제공하여 주위의 다른 노드들 간의 전송 때문에 자신이 전송하지 못하는 경우를 줄였다. 시뮬레이션 결과 제안된 스케줄링 기법이 기존 기법보다 트래픽을 전송할 기회를 가질 확률이 증가되는 것을 볼 수 있다.

Widespread public vaccination is one of the effective mechanisms to ensure the health and prevent deaths in societies. The coronavirus disease 2019 (COVID-19) vaccine is a stark instance in this regard. Vaccine development is a complex process requiring firm-level capabilities, various infrastructures, long-term planning, and stable and efficient policies. Due to the global demand for vaccines during the pandemic, the national capability to produce vaccines is critical. To this end, the current paper investigates influential factors, at the firm- and policylevel, in the COVID-19 vaccine development process in Iran. By adopting a qualitative research method and conducting 17 semi-structured interviews and analyzing policy documents, news, and reports, we extracted internal and external factors affecting the success and failure of a vaccine development project. We also discuss the characteristics of the vaccine ecosystem and the gradual maturity of policies. This paper draws lessons for vaccine development in developing countries at both firm and policy levels.

과거 기업은 고객만족을 통해 고객의 충성도를 구축해 지속적인 이윤을 창출하는데 주로 초점을 맞추었다. 그러나 고객들은 기업에게 긍정적 영향만을 주지 않으며 때로는 기업을 위험에 빠뜨리기도 하고 곤란에 처하게 하기도 한다. 서비스 실패를 경험한 고객에게 기업이 적절한 서비스 회복조치를 취하지 못했을 때 그들은 배신감과 분노 같은 강한 부정적 정서를 느끼며 이러한 부정적 정서는 기업의 성과에 상당한 부정적 영향을 미칠 수 있는 공격적 행동이나 보복행동을 유발 할 수 있다. 고객이 느끼는 이러한 부정적 정서는 기업과 오랜 거래관계를 유지하고 그 기업에 대해 애착을 가진 충성고객에게 더 강하게 발생될 수 있다. 강한 배신감을 느낀 충성고객은 단순히 경쟁기업으로 브랜드 전환을 하는데 머무는 것이 아니라 온라인 부정적 구전, 불매운동, 언론매체를 통한 호소 등의 강력한 보복행동을 수행한다. 본 연구는 서비스 실패요인으로 발생되는 배신감이라는 감정이 보복욕구를 통해 보복행위까지 가는 인과관계에 대해 알아보고, 기업 간의 충성도가 각기 다른 고객들을 분류하여 그 차이를 살펴보았다. 실증분석 결과 각각의 공정성 훼손은 모두 지각된 배신감에 유의한 영향을 미치는 것으로 나타났다. 특히 고객들은 분배 공정성 훼손으로 인한 서비스 실패를 경험하였을 경우 가장 높게 배신감을 지각했으며 절차공정성 훼손으로 인한 서비스 실패를 경험하였을 경우 배신감을 가장 낮게 느끼게 하는 것으로 나타났다. 또한 지각된 배신감은 보복욕구에 유의한 영향을 미치며 이후 부정구전과 보복적인 불평행동, 제3단체를 통한 불만 홍보와 같은 보복행위 모두에 유의한 영향을 미치는 것으로 나타났다. 따라서 공정성 훼손은 지각된 배신감과 보복욕구와 같은 매개변수를 통하여 보복행위에 영향을 미치는 것으로 볼 수 있다. 마지막으로 공정성 훼손과 지각된 배신감과의 관계에서 과거 해당기업과 고객 간의 관계의 친밀도를 나타내는 관계품질의 조절변수 역할을 검증한 결과 관계품질은 조절변수로서 역할을 하는 것으로 나타났다. 본 연구는 서비스 실패 요인이 보복행위에 미치는 영향을 단순 인과관계로 보지 않고 기업과 고객 간의 관계품질의 조절효과를 고려하여 연구를 하였다는 데 그 의의가 있다.

Today's firm runs on a customer-centric environment. Customers prefer to deal with companies that are accessible at anytime, from anywhere, in any form. Thix trend requires an ever-increasing number of channels to interact with the firm. And these channels ought to be integrated as well. To meet these challenges firms tend to rely on a customer interaction center (CIC) solution, enabling two-way interactions with customers through seamless contact channels. Though many firms these days tend to introduce the CIC into their organization, there is not much empirical research dealing with design elements that have to be fabricated in the CIC. This study is to investigate the relationship between CIC design elements and CIC effectiveness. To meet this objective we have contacted and surveyed a number of firms that are operating some form of CIC. We also describe a few success and failure cases in an effort to deliver issues or insights that should be considered in introducing CIC.

This paper reviews various models of technological innovations at different levels: project level and productive segment level. Firstly, it examines a number of significant factors influencing the success and failure of technological innovation at project level. Specifically, the role and characteristics of technical information for the success of innovation is analyzed. Secondly, the paper discusses in detail the relationship between technological innovation and the evolution of a firm. Product and process innovations are analyzed in accordance with a three stage model; the stages are performance maximizing (uncoordinated), sales maximizing (segmental) and cost minimizing (systemic). Various implications of the model are presented in terms of the business policy variables such as diversification, standardization, productivity improvement, marketing, etc. The applicability of the model to a developing country is sought and a few suggestions to develop new model of technological innovations in LDC are discussed.

This paper explores the determinants of the economic value of patents using a survival time analysis. The analysis is based on renewal information of about 250,000 patents filed from 1984 to 2005 in the Korea Intellectual Property Office. A patent right is valid only when its owner pays yearly maintenance fees. Failure to pay causes patent rights to be lapsed. We use the fact that more valued patents live longer and the lengths of their renewals can be closely related to their value. The value can be affected not only by its own technological aspects such as quality and breadth, but also by characteristics of its owners such as innovativeness and age. This paper presents patent-specific and firm-specific characteristics which influence patent value. The result of analysis implies that patent value depends on both the technological contents of the patent and general capabilities of a firm.

Chromic acid is a strong metal acid and acute poisoning is very rare. However, chromic acid causes serious complications, such as skin injuries, as well as renal and hepatic failure. We report on a case of a 47-year-old male who accidentally had chromic acid spilled over his nose and face. For the first few days, he was treated with ascorbic acid and massive hydration. However, after three days, his condition began to worsen. He was treated with hemodialysis for anuria and acute renal failure, and antibiotics for pneumonia. On day 10 of hospitalization, he expired of multi-organ failure. We suggest firm control and close supervision of chromic acid in the work place, and, considering severe complications of chromic acid, we propose a nearly and aggressive treatment.
