Because of the e-shopping market consumers now have diverse options to choose when placing their orders, and find it easy to obtain the required information through the Internet. Especially, for consumers, product reviews posted on an e-tailer's website have become more important criteria than such information available elsewhere. Hence, this study investigated the influence of the direction and evaluative contents of online reviews on consumer attitudes toward clothing products. Four types of online reviews based on direction (positive/negative) and evaluative content in review information (objective/subjective) were used in the experimental design. Further, stimulus reviews were developed. Credibility, usefulness of reviews, product preference, and purchase intention were the measured dependent variables in each of the four situations of online review presentations. The results indicated that, overall, positive and objective online reviews resulted in a higher level of consumer attitude. The content in these reviews had a relatively stronger influence than the direction on attitudes toward online reviews. Overall, objective reviews generated a higher level of credibility and usefulness of information than subjective reviews. Regarding subjective reviews, negative information was more related to credibility, whereas positive information was more related to usefulness. Further, positive information had a higher influence than negative information on consumer attitudes.

Campylobacter spp. are a type of microaerophilic bacteria that cause human foodborne illnesses worldwide. Among the various types of Campylobacter spp., Campylobacter jejuni and Campylobacter coli account for 90% of foodborne campylobacteriosis. Generally, poultry meats are known to be a primary cause of campylobacteriosis; however, several other types of foods have also been reported to cause campylobacteriosis. Particularly, raw milk has been directly linked to Campylobacter infections among many foodborne illnesses, and cases of campylobacteriosis caused because of the ingestion of unpasteurized raw milk have been recorded worldwide. This review reports (1) general information, history, and nomenclature of Campylobacter spp., (2) epidemiology of Campylobacter spp., (3) detection of Campylobacter spp. from foods including milk and dairy products, and (4) review of methods for controlling the growth Campylobacter spp.

Salmonella is one of the principal causes of foodborne outbreaks. As traditional control methods have shown less efficacy against emerging Salmonella serotypes or antimicrobial-resistant Salmonella, new approaches have been attempted. The use of lytic phages for the biocontrol of Salmonella in the food industry has become an attractive method owing to the many advantages offered by the use of phages as biocontrol agents. Phages are natural alternatives to traditional antimicrobial agents; they have proven effective in the control of bacterial pathogens in the food industry, which has led to the development of different phage products. The treatment with specific phages in the food industry can prevent the decay of products and the spread of bacterial diseases, and ultimately promotes safe environments for animal and plant food production, processing, and handling. After an extensive investigation of the current literature, this review focuses predominantly on the efficacy of phages for the successful control of Salmonella spp. in foods. This review also addresses the current knowledge on the pathogenic characteristics of Salmonella, the prevalence of emerging Salmonella outbreaks, the isolation and characterization of Salmonella-specific phages, the effectiveness of Salmonella-specific phages as biocontrol agents, and the prospective use of Salmonella-specific phages in the food industry.

Corrugated board provides packaging for most diverse industries with a share of over 50%, due to the numerous advantages they offer a good protection of the products. In other hand corrugated board fails in environmental conditions, indicating that relative humidity or temperature is higher. These effects directly damage the product packaged. To overcome on this problem recently corrugated boards produced with functional material, "functional corrugated boards," have become more available in the current market. A number of commercialized forms of functional material are coated or composited products with inorganic materials, for example "Nano clay" as representative. However, although the use of functional materials is increasing in corrugated boards, the several concerns such as over cost, environmental friendly materials, recycling, and toxicity affect consumer perceptions and acceptance. In the past, number of researcher focused on process of box compression and the utility of box compression testing etc., best of our knowledge there is no review paper which focus on the functional corrugated boards used in food packaging applications. This paper aims to review the availability of functional corrugated boards in the current market, past research studies on functional material and present the current status of functional corrugated boards in leading countries.

Among various environmental issues, those for worn-out products are increasingly important due to rapid development and improvement of products, shortages of dumping sites and waste-incineration facilities, and legislation pressures and customer recognitions to protect the environment. Under such circumstances, collection and product recovery activities give rise to additional material flows from customers back to collectors and reprocessors. Reverse logistics, the opposite direction of the conventional forward logistics, is concerned with the management of this material flow. In this paper, we consider the emerging concept of reverse logistics. First, the concept of sustainable development is explained to explain the philosophical background of various environmental issues. Second, we explain the basics of reverse logistics, which includes the overall structure and the classification of network types. Finally, we review the previous research articles, especially in the aspect of industrial engineering, after classifying the decision problems into : (a) product recovery strategy; (b) network design and operation; (c) inventory management; (d) disassembly problems; and (e) remanufacturing problems.

Purpose: Fungal secondary metabolite (mycotoxin) contamination in foods can pose a serious threat to humans and animals. Spectroscopic techniques have proven to be potential alternative tools for early detection of mycotoxins. Thus, the aim of this review is to provide an overview of the current developments in nondestructive food safety testing techniques, particularly regarding fungal contamination testing in grains, focusing on the application of spectroscopic techniques to this problem. Methods: This review focuses on the use of spectroscopic techniques for the detection of fungi and mycotoxins in agricultural products as reported in the literature. It provides an overview of the characteristics of the main spectroscopic methods and reviews their applications in grain analysis. Results: It was found that spectroscopy has advantages over conventional methods used for fungal contamination detection, particularly when combined with chemometrics. These advantages include the rapidness and nondestructive nature of this approach. Conclusions: While spectroscopy offers many benefits for the detection of mycotoxins in agricultural products, a number of limitations exist, which must be overcome prior to widespread adoption of these techniques.

제품 성능의 고도화, 구조의 복잡화에 따라서 고객이 요구하는 품질특성도 다양화하고 있다. 따라서 가격, 코스트, 외관, 구조, 기능, 안전성, 신뢰성, 보전성, 사용의 용이성 등을 종합적인 관점에서 검토ㆍ설계하여 생산계획을 세우지 않으면 안 되는데, 한편 기술혁신은 점점 급속히 진척하고 제품개발 기간단축의 필요성에 쫓기고 있다. 제품의 품질은 대부분이 설계시에 만들어지게 되는데, 설계의 초기단계로 넘어가는 시점에서는 평가결과를 종합해서 설계품질의 객관적인 확인을 조직적으로 실시하는 것이 결국은 그 후의 공정단축, 품질 및 코스트 유효성의 확보에 대한 지름길이라고 생각하게 되었다. DR이란 제품의 설계품질 및 그것을 구현하기 위하여 계획된 제조 수송 설치 사용 보전 등의 프로세스에 대해서, 객관적으로 지식을 모아 평가하고 개선점을 제안하며 다음 단계로 나아갈 수 있는 상태에 있다는 것을 확인하는 조직적 활동의 체계라고 할 수 있다. DR의 주된 목적은 설계내용의 검토에 의한 그 자체의 문제점에 대한 해결뿐만 아니라 개발 프로그램 전체의 문제점, 진행상황 등을 모니터함으로써 개발관리를 합리적으로 진척시킨다고 하는 목표도 가지고 있다. 또 이것 이외에도 각 기업의 체질과 상황에 맞춰서 실시되고 있는 DR은 여러 가지의 목표를 가지고 있다.

Digital service transformation study is a part of research in the field of digital transformation, which is devoted to exploring the transformations that occur in digital service products, which have been intensely explored in recent years to address digital disruption. Several concepts and definitions of digital service transformation have emerged as a result of an approach from the point of view of digital transformation and digital services concepts. This paper is organized to provide a foundational understanding of digital service transformation terminology. This paper uses the systematic literature review method to compile 52 qualified articles from previous studies. We conduct an analysis and synthesis of articles to answer research questions. The results of this study are a descriptive summary of research in the digital service transformation field, determining digital service transformation terminology and components, and also a proposed digital service transformation model to explain the position of transformation in digital service products in the overall transformation process. We construct this model using the findings of previously determined components synthesis.
