PSS(Product Service System) 시스템은 제품과 서비스가 하나로 통합되어 고객에게 차별화된 가치를 제공하고, 기업이 경쟁력을 가지고 지속적인 성장을 할 수 있게 지원하는 시스템이다. 본 논문에서는 PSS 시스템으로 성공한 Amazon의 Kindle과 Apple의 iPod, 실패한 Microsoft의 Zune과 Sony의 e-book reader를 채택하여 중다 사례연구 방법론을 통해 성공요인과 실패요인을 도출하고자 한다. 이를 위하여, 사례 분석을 통해 가설을 도출하고, 연관 문헌연구와의 비교 및 분석을 통하여 PSS 시스템에서 상업적으로 성공하기 위한 전략적 시사점을 제시하였다.

계군 수준에서 닭 전염성 기관지염(IBV)을 검출하는데 필요한 표본크기를 추정하기 위하여 강원도 충북 및 충남 지역의 총 9,980수의 산란계로부터 회수된 총 48회의 혈청시료를 사용하였다. 의뢰된 모든 혈청에 대해서는 개별 시료와 크기가 10인 합병혈청(pool)으로 구분하여 HI 역가를 측정하였다. 적어도 1개의 감염된 pool을 검출하는 것을 95%신뢰하기 위해서는 총 48회의 의뢰건 중 5개 이하의 pool이 요구되는 비율이 72.9%를 차지하였고 90% 신뢰수준에서는 77.1%로 나타났다. 전체적으로 볼 때 필요한 pool의 개수는 양성 pool의 개수가 증가할수록 감소하였다. 개별시료에서 양성판정을 위한 HI 역가의 기준을 9 이상과 10 이상으로 설정할 때 혈청 유병율은 각각 50.1%와 33.4%로 나타났으며, 합병혈청에 대한 양성 판정기준을 8 이상으로 설정할 경우 59.9%로 분석되었다. 매 의뢰된 시료에서 개별시료와 합병혈청 간의 상관계수는 판정기준 9 이상에서 0.592(p<0.001), 10 이상에서 0.561(p<0.001)로 두 상관계수간 차이가 없었고 공통상관계수는 0.576으로 나타났다. 이러한 결과에 근거할 때 IBV 감염증을 검출하기 위하여 합병혈청을 사용하는 전략은 조사의 목적이 계군의 감염여부에만 관심을 두는 경우 한가지 대안이 될 것으로 사료된다.

Background: Experience of lung cancer includes negative impacts on both physical and psychological health. Pain is one of the negative experiences of lung cancer. Cognitive behavioral therapy techniques are often recommended as treatments for lung cancer pain. The objective of this review was to synthesize the evidence on the effectiveness of cognitive behavioral therapy techniques in treating lung cancer pain. This review considered studies that included lung cancer patients who were required to 1) be at least 18 years old; 2) speak and read English or Thai; 3) have a life expectancy of at least two months; 4) experience daily cancer pain requiring an opioid medication; 5) have a positive response to opioid medication; 6) have "average or usual" pain between 4 and 7 on a scale of 0-10 for the day before the clinic visit or for a typical day; and 7) able to participate in a pain evaluation and treatment program. This review considered studies to examine interventions for use in treatment of pain in lung cancer patients, including: biofeedback, cognitive/attentional distraction, imagery, hypnosis, and meditation. Any randomized controlled trials (RCTs) that examined cognitive behavioral therapy techniques for pain specifically in lung cancer patients were included. In the absence of RCTs, quasi-experimental designs were reviewed for possible conclusion in a narrative summary. Outcome measures were pain intensity before and after cognitive behavioural therapy techniques. The search strategy aimed to find both published and unpublished literature. A three-step search was utilised by using identified keywords and text term. An initial limited search of MEDLINE and CINAHL was undertaken followed by analysis of the text words contained in the title and abstract, and of the index terms used to describe the article. A second search using all the identified keywords and index terms was then undertaken across all included databases. Thirdly, the reference list of all identified reports and articles were searched for additional studies. Searches were conducted during January 1991- March 2014 limited to English and Thai languages with no date restriction. Materials and Methods: All studies that met the inclusion criteria were assessed for methodological quality by three reviewers using a standardized critical appraisal tool from the Joanna Briggs Institute (JBI). Three reviewers extracted data independently, using a standardized data extraction tool from the Joanna Briggs Institute (JBI). Ideally for quantitative data meta-analysis was to be conducted where all results were subject to double data entry. Odds ratios (for categorical data) and weighted mean differences (for continuous data) and their 95% confidence intervals were to be calculated for analysis and heterogeneity was to be assessed using the standard Chi-square. Where statistical pooling was not possible the finding were be presented in narrative form. Results: There were no studies located that met the inclusion requirements of this review. There were also no text and opinion pieces that were specific to cognitive behavioral therapy techniques pain and lung cancer patients.Conclusions: There is currently no evidence available to determine the effectiveness of cognitive behavioural therapy techniques for pain in lung cancer patients.
