  • This study addresses the issue of the continuity in Indonesia's party system with respect to Islam, authoritarian legacy and income, using the urban-based individual face-to-face survey data. The existing studies focus on the historical continuity of the Indonesian party system between the 1955 and 1999 democratic elections. Yet, this study deals with the continuity and discontinuity between the pre-transitional 1997 election and the transitional 1999 election. It finds that the effect of Islam is largely independent of the democratic transition: Islam-oriented voters under the authoritarian rule tend to remain in the Islamic camp even during and after the democratic transition, while most of the secular voters prior to the democratic transition continue to shun any Islamic parties during the democratization. The effect of authoritarian legacy is also found to be meaningful, even if not as sticky as Islam. Finally, the variable of income is significant. Contrary to the popular belief, the PDIP is not a party of the urban poor but the PPP is the urban poor's favorite choice. This implies the linkage between poverty and political Islam.

  • When we implement the single frequency network (SFN) in ATSC terrestrial DTV system, there is an interference problem to DTV receivers due to the use of same frequency channel among transmitters and repeaters. To resolve this problem, it is recommended to adopt the transmitter identification signals in transmitting equipments. In this paper, we analyzed the influence suffered by legacy DTV receivers when the TxID signal is added to the DTV transmitting signals and the results were further verified by computer simulation, laboratory test and field test. The above tests show that if the TxID signal is added to the level of -30dB compared to the original DTV signal, the TOV(Threshold Of Visibility) increment in legacy receivers is about 0.17 dB. It means that we can insert and transmit the TxID signal in ATSC terrestrial DTV system without making the negative effect to the legacy DTV receivers.

  • Purpose In this study, we investigated the impact of perceived risk and switching costs on switching intention to cloud service based on PPM (Pull-Push-Mooring) model. Design/methodology/approach We focused on revealing the switching factors of the switching intention to the cloud services. The switching factors to the cloud services were defined as perceived risk consisting of performance risk, economic risk, and security risk, and switching costs consisting of financial and learning costs. On the PPM model, we defined the pull factors consisting of perceived usefulness and perceived ease of use, and the push factor as satisfaction of the legacy system, and the mooring factor as policy supports. Findings The results of this study as follows; (1) Among the perceived risk factors, performance risk has a negative effect on the ease of use of pull factors, and finally it was found to affect the switching intention to the cloud services. Therefore, cloud service providers need to improve trust in cloud services, service timeliness, and linkage to the legacy systems. And it was found that economic risk and security risk among the perceived risk factors did not affect the switching intention to the cloud services. (2) Of the perceived risk factors, financial cost and learning cost did not affect the satisfaction of the legacy system, which is a push factor. It indicates that the respondents are positively considering switching to cloud service in the future, despite the fact that the respondents are satisfied with the use of the legacy system and are aware of the switching cost to cloud service. (3) Policy support was found to improve the switching intention to cloud services by alleviating the financial and learning costs required for cloud service switching.

  • This paper is to understand what effects the introduction of IFRS(International Financial Reporting Standard) will have on legacy AIS(Accounting Information System) and how to minimize the problems of that. In order to meet that purpose, we have to recognize the difference between K-GAAP(Korea-Generally Accepted Accounting Principles) and K-IFRS(Korea-International Financial Reporting Standards) first. And then we try to find out what effects the difference between K-GAAP and K-IFRS will have on the legacy AIS. In order to avoid the disorder When K-IFRS will be introduced to the company, new functions have to be added to existing system in proper manner and some existing functions should be changed correctly according to K-IFRS. And CIO(Chief Information Officer) should have to make a careful decision what is the better solution between in-house development and outsourcing for developing new system.

  • This paper proposes a method of applying an advanced preamble detection technology to wireless sensor nodes and analyzes the trade-off relationship between throughput and fairness that may occur when sensor nodes equipped with the MIM function compete with the legacy IEEE 802.15.4 sensors. Sensor nodes employing the MIM capability have more chances of concurrent transmissions than the legacy IEEE 802.15.4-based sensor nodes, resulting in gains in terms of throughput, whereas the transmission opportunities of 802.15.4 sensor nodes might be limited due to the additional simultaneous transmissions of the MIM sensor nodes. The extensive evaluation results performed under a test environment built using Python program with reflecting the setting value of a commercial sensor node shows MIM sensor nodes outperform up to 40% over the legacy 802.11 sensors. Meanwhile, it was confirmed that a balance can be achieved in terms of throughput and fairness by properly adjusting the concurrent transmission threshold.

  • This paper examines the motives for location decisions of startups and dynamics of cluster growth. Because the location decision is intrinsically strategic choice by entrepreneurs, it is an interplay of three critical forces; cost-benefit of the choice, R&D ability of new entrants, and R&D capability of incumbents in clusters. The effect of knowledge spillovers influences the cluster growth like a double-edge sword; both a positive effect of technology learning and a negative effect of knowledge de-learning. Using data on 710 bio-tech venture firms in Korea, this paper tests the hypotheses about the factors influencing the growth of the cluster. The empirical analyses suggested that early entrepreneurial activity in the clustered regions were important, however other factors such as the organizational legacy, internal dynamics inside a cluster, and the existence of cooperation norm in the cluster, affected long term viability of the cluster.

  • Recent technological advancement has a profound effect on the ways that the war is being conducted and fought. The advanced communications, information, computing and sensor technologies enable the combat units to be integrated in the battlefield management network. By exchanging and sharing real-time battlefield information that is critical for the successful outcome of military engagement, the legacy forces are becoming much more effective and lethal than ever before, The bigger picture of such phenomena can be summarized as the concept of Network Centric Warfare(NCW). The main purpose of this study is to compare the outcome of regional combat engagement between the legacy forces and the future combat systems(FCS). The FCS capitalizes on the advanced technologies within the frame of NCW. This study uses the modeling and simulation methodology to assess the effectiveness of two different combat forces. The simulation results show that the FCS is more effective, hence vindicating the superiority of technologically advanced combat units.

  • In patents with diabetes, the higher the serum glucose level was, the more cardiovascular events and death were observed. But with a certain kind of group, to control glucose level tightly does not decrease the incidence of these events. Several studies show that intensive glucose control does not gain benefit in patient with long standing, uncontrolled diabetes, especially having previous cardiovascular events, while definitely preventing progression of newly onset of diabetic nephropathy. Whether intensive glucose control increases mortality in high risk group is obscure and needs more studies with longer observation time.

  • Wireless sensor nodes adopting the advanced preamble detection function, Message-In-Mesage (MIM), maximize the concurrent transmission opportunities due to the capture effect, result in improving the system performance significantly compared to the legacy IEEE 802.15.4 based sensor devices. In this paper, we propose an MIM capture probability model to analyze the performance gains by applying the MIM function to the wireless sensor nodes. We implemented the IEEE 802.15.4 and MIM by Python and performed extensive simulations to verify the performance gains through MIM capture effects. The evaluation results show that the MIM sensors achieve 34% system throughput gains and 31% transmission delay gains over the legacy IEEE 802.15.4-based sensors, which confirm that it was consistent with the analysis result of the proposed MIM capture probability model.

  • Through previous studies, it was found that news from legacy media, including television, has an agenda-setting effect and priming effect on the perceptions and attitudes of audiences about politics and war, and that film media also has an agenda-setting effect and political priming effect on war issues. However, it is difficult to find studies on the effects of war-related TV documentaries on media audiences. Therefore, in this study, An experimental study was conducted to investigate whether there is a change in 'recognition of the importance of security', 'will for South-North Unification' and 'will to participate in war in case of emergency' for the audience who watched the KBS special <100 Days of Invasion of Ukraine, Part 1 into the Fire>. As a result of the analysis, it was found that watching a war-related TV documentary reinforced the audience's 'recognition of the importance of security' and 'will for South-North Unification'. However, it was confirmed that watching a war-related TV documentary did not strengthen the audience's will to participate in war in case of emergency.
