Wireless LAN (WLAN) has greatly benefited from the introduction of various technologies, such as MAC protocol and scheduling algorithm. The majority of these technologies focus on fairness or service differentiation. However, it is difficult to use these technologies to provide many benefits to WLAN simultaneously because the current WLAN system only focuses on the provision of a single aspect of QoS. Unfortunately, multimedia applications require both service differentiation and fairness. Therefore, this paper combines Distributed Fair Scheduling (DFS) and Enhanced Distributed Coordinate Function (EDCF), to provide both fairness and service differentiation simultaneously. Furthermore, we show numerical analysis using Markov process. The simulation results demonstrate that F-EDCF outperforms the EDCF, in terms of throughput, fairness, and delay viewpoints.

The DCF of IEEE 802.11 standard coordinates transmissions onto the shared communication channel based on CSMA/CA protocol. Currently, 802,11 is the most widely deployed wireless LAN standard. In this paper, for 802.11-based wireless LAN we propose a service differentiation scheme adopting different contention window sizes and retransmission schemes for two different types of data packets and we present a Markov model for the state of a given station under a finite load traffic condition. We then derive an algorithm to find the transmission probability and the throughput. The proposed model is validated through simulation under various system settings.

As the technological gap amongst manufacturers decreases, the life cycle of products has shortened, and competition accelerates due to the development of technology, incumbent manufacturing companies face growth limitations. In order to overcome such business issues, manufacturing companies are increasingly interested in changes in business models and innovations, especially in the direction of providing services where they can maintain the competitive advantage of their products. In such context, this empirical study examines managerial leadership, differentiation strategies, and products and services pricing as 'servitization factors', which can be driving forces for moving into a new era of growth for Korean SMEs, focusing on the mediating effects of servitization competency. The results are as follows : First, it was confirmed that executive leadership, differentiation strategy, and information & communication technology capability have a direct effect on service sales. Second, the process competency, partnership competency, and ICT competency, which are presented as the service competence of SMEs, were found to play an important role in inducing service sales in managerial leadership, differentiation strategy, product and services pricing. It also emphasized the role of the public policy such as helping to foster SMEs as key partners in the expansion of social facilities and establishing platforms through ICT and data utilization for the convergence of manufacturing services.

Expanding product variety and high customer service provision place an enormous burden on demand forecasting and the matching of supply with demand in a supply chain. Postponement of product differentiation has been found to be powerful means to improve supply chain performance in the presence of increasing product variety. Delaying the point of product differentiation implies that the process would not commit the work-in-process into a particular finished product until a later point. This paper reviews the recent analytical models that quantify the value of delayed product differentiation. We conclude the literature review by summarizing and synthesizing the economic evaluation of the postponement and outline directions for future research.

This study analyzed the relationship between adult attachment, self-differentiation, and self-esteem in solving the fear of intimacy in interpersonal relationships experienced by adults. This study targeted people in the 20s to 50s age group, and data from 1,263 participants were analyzed using SPSS 23.0 and AMOS 23.0. The results are as follows. First, it was found that secure attachment had a negative relationship with the fear of intimacy, while the relationship between self-differentiation and self-esteem was positive. On the other hand, anxiety attachment and avoidance attachment were shown to have a positive relationship with the fear of intimacy, but a negative relationship was identified with self-differentiation and self-esteem. Second, it became evident that self-differentiation and self-esteem mediated the relationship between adult attachment and the fear of intimacy. Additionally, the findings indicated that self-differentiation and self-esteem had a dual mediating effect. The results of this study can be used as basic data for counseling and educational programs to solve the fear of intimacy in interpersonal relationships experienced by adults.

As online services become more and more popular due to the development of IT, non-face-to-face transactions are continuously increasing rather than face-to-face transactions. The personal identity proofing service(PIPS) based on the alternative method of the resident registration number is used for the purpose of confirming the identity of the other party on the Internet. However, in the case of the current PIPS, the personal information of the PIPS user is excessively provided to the online service provider. As a result, privacy problems of online users, shortage of choice of information providing options, and lack of differentiation of authentication methods are becoming problems. Therefore, this paper proposes a method to improve the PIPS based on the current resident registration number alternative method and to provide a method to differentiate the provision of excessive personal information. In the proposed method, we analyze trends and current status of overseas online PIPS in order to provide a method of providing differentiation of personal information and proposes an effective improvement method applicable to domestic.

Purpose: The objective of this study was to investigate the effects of (6)-gingerol, ginger components proliferation and adipocyte differentiation from early to lately steps. Methods: 3T3-L1 preadipocytes were cultured. Differentiation of confluent cells was induced with dexamethasone, isobutylxanthin and insulin for 2 day and cells were cultured by medium with insulin in presence of various concentrations 0, 25, 50, $100({\mu}mol/L)$ of (6)-gingerol for 4 day. Cell viability was measured using the EZ Cytox assay kit. In addition, we examined the expression of mRNA levels associated with each adipocyte differentiation step by real time reverse transcription polymerase chain reaction. Results: (6)-Gingerol inhibited adipocyte proliferation in a dose and time dependent manner. Expression of $C/EBP{\beta}$, associated with early differentiation step remained unchaged. However, intermmediate, late differentiation step and adipocytokines were effectively changed in dose-dependently manner in cell groups treated with (6)-gingerol. Conclusion: This study has shown that treatment with (6)-gingerol inhibited adipocyte proliferation as well as each adipocyte differentiation step. In particular, the (6)-gingerol more effectively inhibited adipocyte differentiation from intermmediate differentiation step.

In this paper, service differentiation scheme using optical buffer that is reduced in size with slow-light technology in optical burst switching networks is presented. In suggested scheme, each outport has buffer to store high-class burst only in case that all its wavelengths are occupied. When all wavelengths are being used, a new arriving high-class burst goes into the buffer and waits until a burst is serviced. As soon as a burst is serviced with a wavelength, the high-class burst at buffer is allocated to the free wavelength. In case that low-class burst is arriving under the same situation, it is not stored at the buffer but discarded. An analytical model is derived to analyze the performance of the suggested scheme and compare its performance with the conventional scheme such as preemption and deflection as well as no service differentiations.
