Abstract

Purpose

The purpose of this study is to test the concept of a relatively low cost but biocompatible customized surgical guide printing method using a new composite material for the FDM process to support accurate virtual model reconstruction in CT.

Design/methodology/approach

Current additive manufacturing printed surgical guides have problems of scanning artifacts or low computed tomography (CT) values for virtual model reconstruction in CT-assisted surgical operations. These tools always face difficulties in precise positioning due to the effect of human soft tissues and manually made unstable landmarks. To solve this problem, this paper proposes a modified material, polyetheretherketone powder mixed with barium sulfate powder, for printing customized surgical guides with relatively low cost to support a synchronized scanning strategy, for the accurate reconstruction of human tissues and in vitro models.

Findings

A set of benchmarking experiments and clinical simulation cases were conducted. The results showed that the proposed solution can be used to print surgical guides to form stable and clear CT graphs for three-dimensional digital model reconstruction. Human tissues and in vitro models can be accurately reconstructed using clear CT graphs without any scanning artifacts or difficulties in image segmentation for virtual model reconstruction, thus facilitating accurate operation guidance and positioning.

Originality/value

This method has wide application potential for printing modular or customized surgical guides with low cost and reusability, especially for surgical operations using CT-assisted navigation systems in underdeveloped regions where medical device costs are a critical issue.

Abstract

Purpose

The purpose of this study is to examine how guidelines for information literacy and library instruction can be incorporated into online research guides and provide examples from guides that have done this.

Design/methodology/approach

Online research guides in forestry were identified and examined using the ACRL's “Information literacy competency standards for higher education” and guidelines for library instruction set forth in LaGuardia and Oka's Becoming a Library Teacher.

Findings

While some research guides simply provide unannotated links to online resources, others seek to engage the user by incorporating features that correspond directly to elements of a library instruction session.

Originality/value

The study presents practical ways in which online research guides can serve as library instruction tools.

Abstract

Purpose

It is understood that the personality traits and intelligence levels of the tourist guides directly or indirectly affect their ability to solve the problems they encounter on tours. This study aims to test whether emotional intelligence has an intermediary effect on the problem-solving skills of professional tourist guides with perfectionist personality traits.

Design/methodology/approach

Field research was conducted within the study to analyze suggestions on the interaction of variables on an empirical basis, and data were collected using interview, document review and survey technique. Thus, the mixed-methods approach was used in the study. Within the scope of this study in which 410 professional tourist guides were surveyed, a substantial part of the research data was obtained through the application of the survey technique. Besides, interviews were carried out with 12 professional tourist guides. The clues obtained by the qualitative study were transformed into hypotheses within the scope of the quantitative study, and the intermediary effect was tested.

Findings

A relationship between the main themes, sub-themes and codes was determined within the framework of the qualitative method. As a result of the mediation test, it has been revealed that emotional intelligence has an intermediary role in the relationship between perfectionism and problem-solving skills. According to the results of bootstrapping, the indirect effect of emotional intelligence on perfectionism and problem-solving skills was found out to be significant.

Practical implications

The study acknowledged that positive perfectionism, high emotional intelligence and problem-solving skills contributed to the professional tourist guides being willing to provide better service. In tune with the assumption that the more the quality of the tours carried out through agencies increases, the more satisfied tourists are; the study implicated that it would be advisable for agencies to prioritize the trainings provided for their tour guides to enhance their positive perfectionist, emotionally intelligent personalities and problem-solving skills. Given that professional tourist guides may create a positive country image with the quality service they provide, the significance of such trainings stretch beyond the benefits of such organizations.

Originality/value

Relevant variables were analyzed with a mixed method and applied on professional tourist guides.

Abstract

Purpose

Most academic libraries make subject or research guides available on their web sites. Little is known, however, in terms of user satisfaction with guides. This study examines methods used to evaluate guides and reports on an online survey placed on each of more than 80 web‐based guides provided by Gelman Library, George Washington University.

Design/methodology/approach

The survey, borrowing an approach used by Amazon.com and other web sites, consisted of a single question – Was this guide useful – and a comments box.

Findings

Two hundred ten responses were received during Fall semester 2003. Fifty two percent of responses rated guides as Very Helpful or Somewhat Helpful, while 40 percent gave ratings of Not Helpful or a Little Helpful.

Originality/value

Although limited in scope, this simple survey revealed positive elements of the guides and identified problems that could be addressed immediately. The survey also helped to identify larger issues that will benefit from additional user input.

Abstract

When evaluating the worthiness of field guides to trees, there are several criteria which might be considered; perhaps the first should be geographic coverage. If one is attempting to identify a tree in Iowa, one should not be using a guide covering only trees of the Pacific Slope. Although this may seem obvious, problems can occur in guide selection due to geographically misleading titles. Some guides may imply a geographic coverage which is in fact quite different from the actual coverage.

Abstract

Notes that the Department of Health has begun approving industry guides for food safety, including one for the catering industry. Suggests that some in the industry fear these new guides may lead to a lowering of standards or be used as a “stick with which enforcement officers will beat them”. Addresses concerns and explains the rationale behind the guides and advocates a change in approach to food hygiene, from a basic environmental approach to a goal‐based approach of controlling risks. Concludes by stating that the industry guides have a major role in helping to interpret and assist in the regulatory changes and that full involvement of the the various food industry sectors is essential.

Abstract

Purpose

This paper aims to use cone-beam computed tomography (CBCT) and computer-aided design/3D printing technology to design and fabricate a drill guide template for access cavity preparation of permanent molars, and conduct a preliminary evaluation of its effectiveness.

Design/methodology/approach

CBCT scans were performed on two permanent maxillary first molars extracted due to periodontitis. Based on the scans, guide templates of access cavities were designed. The angle of the guiding cylinders was determined based on the direction of the long axis of the tooth. A 3D resin printer with high resolution was used to print the guide templates. The printed guide templates were used by a dentist with specialized clinical experience to perform access cavity preparation in a dental simulator. Then the prepared access cavities were scanned again by CBCT, and scan data were compared to the design data.

Findings

The 3D printed drill guide template had a close fit with the extracted tooth fit. The access cavity prepared using the guide template enabled the removal of the pulp chamber roof, and formed a straight-line access. Points were selected for measurement at regularly spaced intervals of 0.5 mm along the side wall of the access cavity. The mean deviation between the actual access cavities of the two permanent maxillary first molars and the designed cavities was less than 0.1 mm, with a maximum deviation of about 0.5 mm, showing a good conformance between the actual cavity and the designed cavity.

Originality/value

A drill guide template was designed and fabricated by 3D printing technology, which easily guided burs to complete the access cavity preparation work forming an ideal cavity shape with satisfying accuracy, and thus may reduce the complications during pulp chamber entry.

Abstract

Purpose

This study aims to understand the components of the street food experiences of the local-guided tour in the meal-sharing economy based on the online reviews of tourists who experienced a meal-sharing activity with a local guide in Bangkok.

Design/methodology/approach

Based on the qualitative approach, this study involved a content analysis of 384 narratives on Withlocals.

Findings

The study identified five components that embrace the street food experience: a local guide’s attributes, perceived food authenticity, local culture, perceived hygiene or cleanliness. Results also revealed that the Thai street foods are unique and authentic and can reach this experience level through a local guide.

Originality/value

Although the importance of international travellers' street food experiences and the popularity of the meal-sharing economy platforms are rapidly growing, there is no study which had combined both of these phenomena together to date. It is the first attempt to reveal the components of street food experiences in a meal-sharing platform.

Abstract

Company information is of considerable importance to the business community, but finding the right information is not easy. There are many possible information sources in a variety of formats which are often difficult to identify and control. Accurate and current guides to information sources are important and a prototype hypertext guide to sources of company information has been developed to examine the feasibility of utilising this technology to overcome some of the limitations of paper‐based guides. COMPInfo has been developed using GUIDE software. The structure of the system and the way in which this attempts to fulfil the requirements of a good company information guide are discussed. The advantages and problems of the prototype are considered, along with areas in which further development of the structure would be beneficial. In spite of its limitations, COMPInfo indicates that hypertext technology could provide a viable solution to the problems of producing an effective guide to the complex field of company information.
