  • The Cable-In-Conduit-Conductor (CICC) for the ITER tokamak Central Solenoid (CS) has undergone design change since the first prototype conductor sample was tested in 2010. After tests showed that the performance of initial conductor samples degraded rapidly without stabilization, an alternate design with shorter sub-cable twist pitches was tested and discovered to satisfy performance requirements, namely that the minimum current sharing temperature ($T_{cs}$) remained above a given limit under DC bias. With consistent successful performance of ITER CS conductor CICC samples using the alternate design, an attempt is made here to revisit the internal electromagnetic properties of the CICC cable design to identify any correlation with conductor performance. Results of this study suggest that there may be a simple link between the $Nb_3Sn$ CICC internal self-field and its $T_{cs}$ performance. The study also suggests that an optimization process should exist that can further improve the performance of $Nb_3Sn$ based CICC.

  • Due to the recent trend of relationship marketing and characteristics of the apparel retail industry that relys heavily on employees' performance, internal marketing toward the employees gives a critical influence on firms' overall performance. This study is aiming at the factors of internal marketing and relationship management that enhance positive attitude toward change. A survey questionnaire was developed and about two hundreds department store sales staffs working for apparel brands participated in the empirical study. Factor analysis ensured the existence of five aspects of internal marketing: educational training, internal communication, power endorsement, management capability and incentive system. Results indicated that age, marital status, years of employment, position rank, and salary types of salespersons had significant influence on internal marketing factors. Incentive system had significant influence on internal customer relationship management. Internal customer relationship management had significant impact on employees' attitude toward change. Educational training had significant influence on employees' perceived importance of change. Educational training, power endorsement and incentive system affected employees' perceived outcome of change.

  • Innovation is essential for the survival of a company in the fierce competitive environment of the global era of borders along with rapid technological development and changes from the environment. It is very important to secure your own competitive advantage. In this study, the relationship between internal R&D capability and organizational support as a company internal factor and external R&D capability, external knowledge search, and absorptive capability as a company external factor on performance was examined. As a result of the analysis, it was found that internal R&D capability, organizational support, and external knowledge search had a significant effect on absorptive capability, and innovation performance had a positive effect on new product performance. However, the mediating effect of absorptive capacity has not been verified, suggesting that absorptive capacity has a low correlation between innovation performance and new product performance, or that other important factors act between absorptive capacity and performance variables. The results of this study are expected to be utilized as useful guidelines when establishing R&D strategies in companies.

  • In this study, the organizational performance is divided into the policy perspective, the customer perspective, and the internal viewpoint rather than the financial perspective. The public institutions selected as examples of this study are public institutes under the Ministry of Environment, which are established to promote environmental industry development and environmental technology development projects, and promote the dissemination and practical use of developed environmental technologies. The public institutions that were the target of the study were concerned about how to define organizational performance and how to improve organizational performance. In addition, the institutions were interested in measuring performance in terms of customers and policies rather than financial performance. As a result of this study, it was found that the public institutions which were the subject of study were not very high in terms of policy, customer, and internal performance. In order to enhance the organization's policy performance, customer performance and internal performance, it is necessary to communicate smoothly among the members of the organization, horizontal organizational structure, encourage participation in the client's policy process, and redesign the business process from the customer's perspective.

  • This study tried to find out implementation factors of internal marketing for a cosmetic retailer, and to look into their effects on Salesperson's job satisfaction, organization commitment, customer orientation and sales performance. For this, this study inquired into the concepts and relationships of internal marketing, job satisfaction, organization commitment, customer orientation and sales performance through literature review; and tested the relationships between the variables by setting up a research model and hypotheses. The findings of this study may be summarized as follows: First, it was found that the better the education & training, the supervisor support and the compensation system among internal marketing factors of a cosmetic retailer were, the higher a door-to-door salesperson's job satisfaction was. Second, it was found that the better internal communication and the education & training among internal marketing factors of a cosmetic retailer were, the higher a door-to-door salesperson's organization commitment was. Third, the higher the job satisfaction of a door-to-door salesperson in a cosmetic retailer was, the higher the organization commitment was. Fourth, it was found that the higher the organization commitment of a door-to-door salesperson in a cosmetic retailer was, the higher the customer orientation was. Fifth, it was found that the higher the organization commitment and customer orientation of a door-to-door salesperson in a cosmetic retailer were, the higher the sales performance was. In conclusion, the internal marketing increases door-to-door Salesperson's job satisfaction, and enhances the sense of belonging to their cosmetic retailer. Further, they come to have a customer-oriented attitude in serving customers, which is directly connected to sales performance, and thus the retailer can create profits through internal marketing. Therefore, a cosmetic retailer will need to strengthen internal communication activities through diverse methods, expand and activate employees' professional education, and develop fair and just compensation system; and supervisors will need to give support to employees, trusting their judgment.

  • This study was conducted from December 26, 2018 to January 4, 2019 in order to analyze the effects of hospital internal marketing on job performance and loyalty based on nurses' perception. The participants were 250 nurses at general hospitals located in Gyeonggi-do. The results of this study are as follows: First, internal marketing in hospitals had a statistically significant effect on organizational and future vision, education and training systems, communication, organizational attributes, and job performance (F=29.118, p<.001). The training system, organizational and future vision, compensation and welfare system, and work management environment were found to have a statistically significant effect (F=38.671, p <.001) on loyalty, and the effect of job performance on loyalty was statistically significant (F=87.324, p<.001). Second, the relationship between hospital internal marketing based on nurses' perception and loyalty was found to have a statistically significant positive (+) effect on stage 1 job performance (p<.001) and a statistically significant positive effect on stage 2 loyalty (+) (P <.001). The third-level internal marketing regression coefficient was significant, and job performance was also significant (P <.001). Based on these results, there is a need for hospital management to strengthen internal marketing in order to increase performance level and loyalty among nurses.

  • The objective of this study is to examine the relationship of organizational justice, project performance and internal and external PMO (Project Management Office) capability by conducting survey of IT project participants worked with PMO. This study was the first case which classifies PMO capability into internal and external by ownership of PMO. PLS-SEM analysis, which used for this study shows internal PMO capability connects with distributive justice and procedural justice, and directly related to project performance. By comparison, external PMO capability has relationship only with procedural justice, but never related to project performance. Furthermore, distributive justice and procedural Justice all have correlation with project performance. In general, capability of external professional consulting firms is utilized for the fairness and objectivity in spite of sufficient internal project management capability. However, the internal PMO capability has greater influence on procedural justice than external's (internal PMO capability > external PMO capability). Also, distributive justice and project performance have direct correlation only with the internal PMO capability. This paper will be an indicator of finding human capabilities which are necessary for internal and external PMO performance, and has great significance of laying a groundwork of project management strategy by PMO.

  • In the very low specific speed range ($n_s=0.24$ < 0.25, non-dimensional), the efficiency of centrifugal pump designed by a conventional method is very low in common. Therefore, positive-displacement pumps have long been used widely. Recently, since the centrifugal pumps are becoming higher in rotational speed and smaller in size, there expects to develop a new centrifugal pump with a high performance to replace the positive-displacement pumps. The purpose of this study is to investigate the internal flow characteristics of a very low specific speed centrifugal pump and to examine the effect of internal flow pattern on pump performance. The results show that the theoretical head definition of semi-open impeller should be revised by the consideration of high slip factor in the semi-open impeller, and the leakage flow through the tip clearance results in a large effect on the impeller internal flow. Strong reverse flow at the outlet of semi-open impeller reduces the absolute tangential velocity considerably, and the decreased absolute tangential velocity increasese the slip factor with the reduction of theoretical head.

  • Performance of solid oxide fuel cells (SOFCs), in comparison with that under hydrogen fuel, were investigated under direct internal reforming conditions. Anode supported cells were fabricated with an Ni+YSZ anode, YSZ electrolyte, and LSM+YSZ cathode for the present work. Measurements of I-V curves and impedance were conducted with S/C (steam to carbon) ratio of ~ 2 at $800^{\circ}C$. The outlet gas was analyzed using gas chromatography under open circuit condition; the methane conversion rate was calculated and found to be ~ 90% in the case of low flow rate of methane and steam. Power density values were comparable for both cases (hydrogen fuel and internal steam reforming of methane), and in the latter case the cell performance was improved, with a decrease in the flow rate of methane with steam, because of the higher conversion rate. The present work indicates that the short-term performance of SOFCs with conventional Ni+YSZ anodes, in comparison with that under hydrogen fuel, is acceptable under internal reforming condition with the optimized fuel flow rate and S/C ratio.

  • Knowledge is an essential strategic weapon for sustaining competitive advantage and is the key determinant for organizational growth. When knowledge is shared and disseminated throughout the organization, it increases an organization's value by providing the ability to respond to new and unusual situations. The growing importance of knowledge as a critical resource has forced executives to pay attention to their organizational knowledge. Organizations are increasingly undertaking knowledge management initiatives and making significant investments. Knowledge sourcing is considered as the first important step in effective knowledge management. Most firms continue to make an effort to realize the benefits of knowledge management by using various knowledge sources effectively. Appropriate knowledge sourcing strategies enable organizations to create, acquire, and access knowledge in a timely manner by reducing search and transfer costs, which result in better firm performance. In response, the knowledge management literature has devoted substantial attention to the analysis of knowledge sourcing strategies. Many studies have categorized knowledge sourcing strategies into intemal- and external-oriented. Internal-oriented sourcing strategy attempts to increase firm performance by integrating knowledge within the boundary of the firm. On the contrary, external-oriented strategy attempts to bring knowledge in from outside sources via either acquisition or imitation, and then to transfer that knowledge across to the organization. However, the extant literature on knowledge sourcing strategies focuses primarily on large organizations. Although many studies have clearly highlighted major differences between large and small firms and the need to adopt different strategies for different firm sizes, scant attention has been given to analyzing how knowledge sourcing strategies affect firm performance in small firms and what are the differences between small and large firms in the patterns of knowledge sourcing strategies adoption. This study attempts to advance the current literature by examining the impact of knowledge sourcing strategies on small firm performance from a holistic perspective. By drawing on knowledge based theory from organization science and complementarity theory from the economics literature, this paper is motivated by the following questions: (1) what are the adoption patterns of different knowledge sourcing strategies in small firms (i,e., what sourcing strategies should be adopted and which sourcing strategies work well together in small firms)?; and (2) what are the performance implications of these adoption patterns? In order to answer the questions, this study developed three hypotheses. First hypothesis based on knowledge based theory is that internal-oriented knowledge sourcing is positively associated with small firm performance. Second hypothesis developed on the basis of knowledge based theory is that external-oriented knowledge sourcing is positively associated with small firm performance. The third one based on complementarity theory is that pursuing both internal- and external-oriented knowledge sourcing simultaneously is negatively or less positively associated with small firm performance. As a sampling frame, 700 firms were identified from the Annual Corporation Report in Korea. Survey questionnaires were mailed to owners or executives who were most erudite about the firm s knowledge sourcing strategies and performance. A total of 188 companies replied, yielding a response rate of 26.8%. Due to incomplete data, 12 responses were eliminated, leaving 176 responses for the final analysis. Since all independent variables were measured using continuous variables, supermodularity function was used to test the hypotheses based on the cross partial derivative of payoff function. The results indicated no significant impact of internal-oriented sourcing strategies while positive impact of external-oriented sourcing strategy on small firm performance. This intriguing result could be explained on the basis of various resource and capital constraints of small firms. Small firms typically have restricted financial and human resources. They do not have enough assets to always develop knowledge internally. Another possible explanation is competency traps or core rigidities. Building up a knowledge base based on internal knowledge creates core competences, but at the same time, excessive internal focused knowledge exploration leads to behaviors blind to other knowledge. Interestingly, this study found that Internal- and external-oriented knowledge sourcing strategies had a substitutive relationship, which was inconsistent with previous studies that suggested complementary relationship between them. This result might be explained using organizational identification theory. Internal organizational members may perceive external knowledge as a threat, and tend to ignore knowledge from external sources because they prefer to maintain their own knowledge, legitimacy, and homogeneous attitudes. Therefore, integrating knowledge from internal and external sources might not be effective, resulting in failure of improvements of firm performance. Another possible explanation is small firms resource and capital constraints and lack of management expertise and absorptive capacity. Although the integration of different knowledge sources is critical, high levels of knowledge sourcing in many areas are quite expensive and so are often unrealistic for small enterprises. This study provides several implications for research as well as practice. First this study extends the existing knowledge by examining the substitutability (and complementarity) of knowledge sourcing strategies. Most prior studies have tended to investigate the independent effects of these strategies on performance without considering their combined impacts. Furthermore, this study tests complementarity based on the productivity approach that has been considered as a definitive test method for complementarity. Second, this study sheds new light on knowledge management research by identifying the relationship between knowledge sourcing strategies and small firm performance. Most current literature has insisted complementary relationship between knowledge sourcing strategies on the basis of data from large firms. Contrary to the conventional wisdom, this study identifies substitutive relationship between knowledge sourcing strategies using data from small firms. Third, implications for practice highlight that managers of small firms should focus on knowledge sourcing from external-oriented strategies. Moreover, adoption of both sourcing strategies simultaneousiy impedes small firm performance.
