This paper aims to elucidate the collaborative mechanism of knowledge collaboration in online communities. The effects of participant communication behaviors enabling knowledge collaboration, such as public discussion, private messaging and registration, are comprehensively investigated in relation to individual and group performances.

Eight communication categories of participants are defined according to their communication behaviors, and the average number of knowledge contributions at the individual level and the helpfulness toward collaboration efficiency at the group level are compared across the participant categories.

The results show that simultaneous participation in both task-oriented public discussion and relationship-oriented private messaging has a synergistic effect in promoting individual knowledge sharing, and that additional registration – disclosing one’s identity – significantly enhances efficiency in group collaboration. The role of public discussion appears to be as significant as that of private messaging with regard to online knowledge collaboration.

First, encouraging members to participate in both task-oriented discussion and casual personal communication is important for eliciting more knowledge contributions. Second, although social capital based on one-to-one private messaging has attracted much attention with respect to knowledge sharing, many-to-many public discussions that more deeply and broadly influence knowledge conversion should be more highly emphasized. Third, the perceptions of shared value and reputation based on registration also need to be cultivated to increase collaboration efficiency.

In contrast to most previous research that focused on only one type of communication, this study offers a big-picture view of the relationship between communication and online knowledge collaboration by adopting a comprehensive approach to participant communication behavior. A systematic classification of communication behaviors enables this work to illuminate the diverse effects of different communication types or styles on both individual- and group-level performances, thereby improving the understanding of the overall collaborative mechanism. This study thus provides fresh insights on effective management of online communities.

This study aims to investigate the relationship between building smart factories in manufacturing small- and medium-sized enterprises (SMEs) and firm performance and the moderating effect according to product complexity and company size.

Data were collected from 206 companies selected in the list of SMEs, which had built smart factories, provided by the Smart Manufacturing Innovation Center in Korea. The collected data were analyzed using structural equation modeling (SEM) technique.

First, production automation and big data utilization are associated positively with productivity, but not significantly with export performance. Second, supply chain integration is associated positively with both productivity and export performance. Third, product complexity moderates negatively the relationship of productivity with each of production automation, big data utilization and supply chain integration while moderating positively the relationship between supply chain integration and export performance. Finally, company size does not moderate significantly the relationship between productivity or export performance with any of production automation, big data utilization and supply chain integration.

This study contributes theoretically to literature by demonstrating the usefulness of building smart factories and suggesting how SMEs build a smart factory to enhance productivity and export performance from a business perspective. Moreover, this study contributes practically by proposing that SMEs should put priority on supply chain integration over production automation and big data utilization and execute different strategies of building smart factories depending on product complexity.

This study aims to investigate the impact of the loyalty program members’ satisfaction toward the hotel loyalty program benefits and the customer management relationship initiatives of individual hotels on the brand relationship quality (BRQ), i.e. their relationship quality with the hotel brand, and its outcomes. The moderating impact of membership level on the hypothesized relationships was also investigated.

A usable sample of 920 active members of a hotel loyalty program was obtained. Structural equation modeling with partial least squares method was used to estimate the structural relationships and to investigate the moderating effect of membership level.

Employee’s customer orientation, membership communication and hotel stay-related benefits are determinants of the loyalty program members’ BRQ. BRQ is also confirmed as a higher-order construct of three latent variables which include trust, satisfaction and commitment. Moderating effects of the membership were partially supported in this study. The strongest effect of BRQ is on members’ word of mouth followed by shares of purchase. BRQ is found to have negative relationship with members’ willingness to serve as marketing resource, but the impact was small.

This is a cross-sectional study with a population of active loyalty program members of only one luxury hotel group. The sample size of the top-tier members is also smaller in comparison to the other two groups.

This study contributes to the understanding of the antecedents and consequences of BRQ and the body of knowledge about loyalty program for hotel industry.

This is one of the few studies investigating the effectiveness of hotel loyalty programs from the active members’ perspective and the moderating effect of membership level on the relationships among BRQ, its antecedents and its outcomes.

This study explores the effects of interdisciplinary education on engineering students by observing students' competencies before and after the programme.

The effects of interdisciplinary education were studied over three years through the use of a survey to test the social competencies of organisational life and the interdisciplinary competencies of college students. A total of 5,185 responses were collected from engineering students who took part in interdisciplinary education programmes. The survey was conducted during weeks 3 and 14 of each semester, and a comparison test was used to reveal any changes.

Among the 12 competencies developed or adapted, leadership significantly improved during all six semesters. Analytical thinking, interpersonal competency, professional attitude, global-mindedness, and creative attitudes also improved in some of the semesters.

It was not possible to control for the effect of classes that students were attending in addition to the targeted interdisciplinary class. However, this study was able to examine empirically the improvement of competencies for future engineers, and its findings provide a basis for future researchers to elaborate on other competencies as well.

The study recommends competencies needed by engineers working in the Fourth Industrial Revolution, examining the effects of interdisciplinary education on competency development. It contributes to strengthening the current trend in universities that seek to reform interdisciplinary education by empirically verifying its effectiveness.

The purpose of this paper is to discover the primary components of credibility of three types of online newspapers and how the credibility of news differs by type.

The paper participants were recruited at a large north‐eastern US university. All items of credibility scales were measured using seven‐point Likert‐type scales. For each of the three credibility scales, the mean was computed and the scales were analysed for similarities and differences. The scales were factor analysed to determine their underlying dimensions.

Three factors (expertise, trustworthiness, and attractiveness) were common to the three types, but the different factor structure of each type was identified. The result of multiple comparisons shows that the differences between all three types of online newspapers were significant. Also the summated scores of the mainstream type were the highest on most items. However, the summated score of the index type of online newspaper was the highest on attractiveness. Overall participants rated the independent type of online newspapers lowest in credibility.

The limitations and implications of findings are examined in three dimensions: theoretical implications, implications for the online newspaper industry, and implications for strategic media use.

The paper divides online newspapers into three categories according to their characteristics: mainstream, independent, and index type. These three types of online newspapers were evaluated in terms of credibility structure, which made this study useful and unique.

This study suggest the development of a wearable orthotic device pattern that can reduce pain and deformation, and help in the normal development of children with cerebral palsy. Such a pattern enables daily wear before hip subluxation occurs, to prevent hip dislocation and subluxation.

This study set the design line by carrying out cell work on the actual model, then proceeded with the first pattern design. The final version of the second orthotic device was designed by conducting discussions with experts and the patient's guardian, with the device fitted to the child patient. The evaluation of the second orthotic device used the virtual model to check the pressure area and level through virtual fitting. An evaluation was then conducted with the device fitted to the child patient, to verify the functionality and suitability of the final pattern.

Following the initial fitting evaluation, the second pattern was presented after modifying and supplementing issues such as movement suitability with posture change, position change of the great trochanter when wearing a diaper, pressure control of the X-shaped band on the genital area and thigh abduction. The master pattern of the final version of the second orthotic device was proposed after confirming that the femoral head of the hip joint was stably fixed, and the compression was applied through a verification based on the virtual fitting using the virtual model, and with the device fitted to the child patient.

With this study, it is expected that the process and design plan for the development of wearable orthotic device patterns for the persons with disabilities impaired mobility can be used as a basic resource to create devices that merge the clothing and medical fields.

The overall goal of science is to build a valid and reliable body of knowledge about the functioning of the world and how applying that knowledge can change it. As personnel and human resources management researchers, we aim to contribute to the respective bodies of knowledge to provide both employers and employees with a workable foundation to help with those problems they are confronted with. However, what research on research has consistently demonstrated is that the scientific endeavor possesses existential issues including a substantial lack of (a) solid theory, (b) replicability, (c) reproducibility, (d) proper and generalizable samples, (e) sufficient quality control (i.e., peer review), (f) robust and trustworthy statistical results, (g) availability of research, and (h) sufficient practical implications. In this chapter, we first sing a song of sorrow regarding the current state of the social sciences in general and personnel and human resources management specifically. Then, we investigate potential grievances that might have led to it (i.e., questionable research practices, misplaced incentives), only to end with a verse of hope by outlining an avenue for betterment (i.e., open science and policy changes at multiple levels).

The purpose of this paper is to propose the swimsuit patternmaking method suitable for the body shapes of middle-aged women and to propose the swimsuit pattern development procedures that enable automated swimsuit patternmaking.

To propose the patternmaking method of the swimsuit, which is suitable for the body shape of middle-aged women, the swimsuit patterns were developed in three stages in this study. The measurements of the middle-aged woman body model were compared with the size of the developed pattern in each stage, and the optimal stretch rate of the fabric was defined. In total, 22 items were used for size analysis of developed patterns in each stage.

The swimsuit patternmaking method proposed in this study was derived by considering the body shapes of middle-aged women, desired design and fabric characteristics. Also, a series of processes, including obtaining a raw pattern from the surface of the three-dimensional (3D) human body, designing patterns by the expert, evaluating patterns, drafting the final pattern and the final patternmaking method, was presented.

This study has great significance to provide a manual of swimsuit patternmaking for middle-aged women, which has high tightness and movement compatibility.

The swimsuit patternmaking method proposed in this study is relatively simple because it is based on the human body measurements and delivers the lines and the calculated values clearly and objectively rather than the patterner's intuition does so that it is suitable for the automation of the swimsuit patternmaking for the middle-aged women.

Size fit and economic efficiency are two crucial aspects that need to be considered in designing a sizing system. However, there could exist a trade-off between those aspects in order to establish a practical sizing system. The purpose of this paper is to develop a sequential hybrid method of grid and optimization to generate a practical sizing system using anthropometric data.

The proposed sequential hybrid method consisted of two sequential steps, which employs grid method and optimization method. In the initial step, the grid method creates primary grids that accommodate a designated percentage (e.g. 90%) of users with best size fit. In the subsequent step, the optimization method generated additional grids to provide acceptable fit, with minimum fit penalty scores for users unaccommodated by the primary grids. Our method was applied to the development of a sizing system for men's military jackets. The proposed method performances were evaluated in terms of accommodation percentage, size fit and number of sizing categories.

Our proposed method resulted in 26 primary grids during the initial step, which cover 90% of users. Next, we generated six additional grids during the subsequent step that provide minimum fit penalty scores for the rest (10%) users.

The main contributions of this paper are as follows: consider accommodation percentage, size fit and number of sizing categories in the design of sizing system; combine the grid and optimization methods and evaluate a sizing system for men's military jackets. The proposed method is applicable to develop optimal sizing systems for multiple-size products.

The purpose of this paper is to investigate the impact of environmental uncertainty (EU) on supply chain management (SCM) in Korea, and assess the moderating role of organizational culture.

Quantitative data analysis was conducted on data that were collected from 125 Korean manufacturing firms listed on the Korean Stock Exchange. First, structural equation modeling was employed to test the hypothesized paths. Second, multi-group analysis was used to explore the possibility of differences between groups with diverse organizational cultures. Before testing the measurement model, confirmatory factor analysis was run to test the reliability and validity of the measurement items.

The findings indicate that all the hypotheses on the relationships between EU, SCM antecedents and SCM activities are supported except the relationship between commitment and cooperation. The outcome of the multi-group analysis shows that the impact of EU on SCM antecedents varies across organizational cultures.

This study proposes managerial guidelines for implementing effective SCM in response to EU and emphasize that these are consistent with organizational culture.
