Knowledge has become an important resource for organization. The manufacturing industry is usually operated on the basis of business processes, and most workers are familiar with their own processes. The process-based approach, therefore, can provide an efficient way to capture and navigate knowledge. In this study, we focus on knowledge which may be missed during knowledge transfer among workers. For this, we propose a method for analyzing knowledge flow, which is passed among business processes. We propose a process-based knowledge management framework for analyzing knowledge flow, which employs a two-phase analysis: process analysis and knowledge flow analysis. A knowledge flow model, represented by Knowledge Flow Diagram, is proposed as a tool for representing knowledge. We formulate several semantics for knowledge flow modeling. We build the three-level schema: conceptual, logical, and physical in order to automate the knowledge model adaptive to knowledge management systems. The proposed approach is verified and illustrated through a case study on the manufacturing process of A Company.

The purpose of this study was to investigate the influence of Perceived Organizational Support(POS) and on Organizational Citizenship Behavior through Organizational Commitment(OC). In order to attain the objectives of this study, a model was established and hypothesis was verified on the basis of preceding studies. In a model proposed for this study, POS was used as antecedents to OC while OCB was used as consequences for OC. The sample included 387 employees. Structural equation modeling(SEM) was used to employed the hypothesized relationships in the conceptual model. Results indicated that (a)POS has a positive impact OC; (b)affective OC has a positive impact OCB; (c)continuance OC has a negative(or zero) impact QCB. Implications are discussed and future research directions are outlined.

The number of horizontal tower cranes, major hoisting machineries for lifting approximately 50% of entire materials in construction projects, is rapidly increasing, but a number of accidents related to the tower cranes are being continuously occurred in construction sites as well. In particular, telescoping works in the horizontal tower cranes have showed the greatest safety concerns such as falls and collapses. It is due to the fact that tasks inserting a new mast in the space made after raising telescoping cage by fluid pressure and ascending it to the required height in the telescoping works include a series of dangerous factors in safety aspects, and might cause very serious and unexpected accidents in construction sites. The primary objective of this research is to propose two conceptual models for automating the telescoping work in horizontal tower crane and conduct their technical feasibility analyses. In this study, a design concept, a position control system using hydraulic cylinders is suggested as a better alternative for automating the telescoping work. Its potential safety improvement rate compared to the conventional method is also analyzed and presented in this study.

Up to the present, most of the previous works, related to the alignment of organizations, have been focused on the alignment between business and information technology. Also these works have been done with single element, e.g., view rather than with overall elements such as view, scope, and perspective for enterprise-wide integrated alignment. Meanwhile, an enterprise architecture is a blueprint that represents the structure of components of organizations and their interrelationships. Nowadays, many organizations attempt to make enterprise-wide alignment of business and information technology based on enterprise architecture. Unfortunately, the enterprise-wide alignment is still in a stage of not only conceptual level but also abstract level. Hence, this paper proposes a structured enterprise-wide alignment model to overcome the limitations of existing alignment models. We survey the existing works and propose the conceptual, the logical, and the physical models for enterprise-wide alignment which includes 3-dimensional elements such view, scope, and perspective based on enterprise architecture. Finally, we have shown that the proposed model is better than existing ones through comparing the characteristics of models.

The effectiveness of joint operations depends on Jointness based on interoperable elements of participating forces. Many specialists have actively done research studies on interoperability measurement models with the goal of straightforward way of measuring and then have improved the interoperability of elements based on DOTMLPF-p (Doctrine, Organization, Training, Materiel, Leadership & Education, Personnel, Facilities, Policy) in the forces. After the survey of 16 interoperability measurement models, we have concluded that most of them applied only a small portion of DOTMLPF-p elements explicitly or all portions of DOTMLPF-p elements implicitly. In this study, we propose a conceptual interoperability measurement model for applying all DOTMLPF-p elements explicitly. And it can evaluate not only the level of interoperability among forces but also level of jointness for joint operations.

This study investigated the relationship between fashion behavior, impression management behavior, and career success. A conceptual model and hypotheses were established based on theoretical linkages between the constructs. Thereafter, empirical data were collected using a set of questionnaires. For this reason, the sample was taken from 720 office workers' who worked at 14's Korea Enterprise, 697 of which was used for an empirical analysis (sample: men over 30 years of age and more than three years continuous service). This study conducted an exploratory factor analysis and confirmatory factor analysis for the validity test. Cronbach's alpha test is used for the reliability test. Moreover, PLS structural equation modeling (SEM) was employed to test hypothesized relationships in the conceptual model (SPSS 20.0 window/Smart PLS 3.0). This study shows that the proposed model is reasonably fit to the actual data. The following results were obtained from the analyses. First, fashion behavior and impression management behavior is positively related to career success. The result shows that economics of the fashion behaviors sub-types were statistically more significant to influence career success. The self-focused of the impression management behavior sub-types were more than statistically significant to influence career success. This finding has great implications to understand self-management behavior and the career success of male office workers.

The purpose of this study is to examine the effect of leader-member exchange(LMX) on employee's affective commitment and continuance commitment focusing on the mediating role of job stress. On the basis of theoretical linkages between the constructs, a conceptual model and hypotheses were established. The sample included 482 employees. Structural equation modeling(SEM) was employed to test the hypothesized relationships in the conceptual model. This study shows that the proposed model is reasonably fit to the actual data. Empirical results indicate that LMX has a negative impact on employee's job stress, has a positive impact on employees' affective commitment and continuance commitment. Employees' job stress has partially mediated effect on the relationship between LMX and employees' affective commitment, but has not mediated effect on the relationship between LMX and employees' continuance commitment.

In this paper, we drew upon IMP group's Interaction model to investigate the contributing impact of Inter-organizational system (IOS) on performance through enhancing inter-organizational relationship. While most extant literature studied the contribution of IOS from transaction efficiency perspective, the relational aspect of IOS contribution on the supply chain was addressed only by a few researches. As such, we intended to fill this gap of the IOS research stream. The conceptual model was developed, with reference to process theory, to analyze how the relational perspective could be applicable to IOS impact on performance. With the 129 sample data collected at the firm level,structural equation model using the LISREL was employed to validate the proposed research model. The empirical results supported the hypotheses such as the extent of IOS usage positively influences the interaction between the firms, which thereby enhances the extent of inter-firm partnership and performance. The results help better understanding the strategic use of IOS from relationship perspective.

Many science teaching models have been devised and published for the students' conceptual change by researchers. However, the science teachers have been confused with so many models to be used in teaching science. Since the models are composed of ambiguous statements, it seems to be difficult for the teachers to understand their characteristics and natures. Therefore, the models were difficult to be adopted in science instructions. In this study, the researcher developed two checklists which were devised especially for the teachers who apply the Cognitive Conflict Process Model (the Procedural Teaching Model using Cognitive Conflict Strategy) in Science Concept Instruction. One is for planning instructions using the model, the other is for examining or analysing them. Each of them consisted of 20 items and 33 items, respectively. Using these checklists, the Cognitive Conflict Process Model can be checked whether it was applied properly in actual instruction or not.
