Two new impulsive driving technologies for 120Hz liquid crystal display (LCD) panels are proposed to improve moving picture quality. One technology generates the dark frame using an adder and a shifter simply without using any look up tables (LUTs). It results in a cost effective impulsive scheme with motion picture quality comparable to that of high speed driving. The other is a backlight flashing method designed to avoid ghost images. The issue of ghost images caused by the slow response time of liquid crystal (LC) is solved by means of 120Hz overdriving and 120Hz backlight flashing. Using the perceived blur edge time (PBET) metric, measured moving picture response time (MPRT) values were 10.8ms and 4.4ms, respectively, while that of 120Hz high speed driving was 10.1ms.

With the acceleration of regional economic integration, the agricultural trade network within the RCEP region presents new opportunities and challenges for member countries. This study focuses on agricultural trade among RCEP members from 2011 to 2020, utilizing social network analysis to explore the structural characteristics and evolutionary trends of the trade network. Additionally, an extended gravity model is employed to empirically analyze the key factors influencing South Korea's agricultural trade with other member countries. The findings reveal that: (1) Agricultural trade relationships within the RCEP region are stable and mature, with high interconnectivity in the trade network, indicating a trend towards balanced development. (2) The positions of member countries within the agricultural trade network are characterized by both high density and heterogeneity. (3) South Korea's agricultural trade with RCEP member countries is positively influenced by the economic size, population size, and governance level of its trading partners, while South Korea's own indicators show no significant effect. The trade distance between South Korea and member countries also has a positive impact on agricultural trade. By combining social network analysis with an extended gravity model, this study provides a multi-faceted quantitative analysis of the RCEP agricultural trade network, offering new insights into regional agricultural trade. It also provides empirical evidence for agricultural trade cooperation between South Korea and other RCEP countries.

The semantics of whole involves distributivity, which may not be accounted for by the distributive operator for plurals or quantifiers. I review the pragmatic approach to whole by Moltmann (2005) and propose that the semantics of whole can be explained by the member specification function, which maps a group to its members. Although NPs with whole are morphologically singular, they become semantically plural with the application of the function. The distributive operator for plurals is introduced on a sentence with whole, which explains the distributivity of whole.

IDM is a methodology for capturing and specifying processes and information flow during the life-cycle of a facility. The methodology can be used to document existing or new processes, and describe the associated information that need to be exchanged between parties. In this paper, the information model for BIM-based structural steel member design was defined using IDM methodology. The structural information offered in IFC was analyzed, and its adequacy was verified by applying the case study using Excel. As a result, $IFC2{\times}3$ offers the most structural design information for BIM-based structural steel member design, and some sectional properties omitted in $IFC2{\times}3$ were offered in IFC4. IDM methodology can be used effectively for developing BIM-based structural design systems.

In this paper, we propose a new routing protocol for wireless sensor networks. This protocol improves energy consumption of ML-LEACH by reducing the transmission distance of member node via Relay Node. Since clusters of each Layer in ML-LEACH are randomly formed, the distance, between member node and cluster head may be longer than specific distance, distance threshold value. To improve this, we propose the new routing protocol using 2-Hop transmission via Relay Node depending on the transmission distance of the member node.

Team decision making is a collective behavior that needs to be understood by considering properties belonging to team and individual member domains together. This paper introduces a conceptual model called "Dual-Level(DL)" model that describes a team decision-making process in terms of team level, member level, and the relationship between them. The team-level view explains the decision-making process by considering the team as a wholeand divides the process into three stages: Problem Conceptualization, Alternative Generation, and Selection. The member-level view describes what happens to individual members when they go through the group process and splits it into the five phases: Individual Cognitive Mapping, Problem Decomposition, Subproblem Session, Subproblem Integration, and Team Decision. The DL model works as a theoretical framework to explore team decision making by using a set of computational models of team design and team members. In practice, the conceptual framework is used to build a computational model of decision making team, called "Team-Soar."

Mobile phones use the embedded memory in LDI (LCD Driver IC). In memory accessing mode, data overlapping phenomenon can occur. These days, various contents such as DMB, Camera, Game are merged to phone. Accordingly, with more data transmission, there would be more data overlapping phenomenon in memory accessing mode. Human eyes perceive this data overlapping phenomenon as simply horizontal line noise. The cause of the data overlapping phenomenon was analysed in this paper. The data overlapping phenomenon can be changed by the speed of data transmission between the host and LDI. The optimum memory accessing position can be defined. This paper proposes a new algorithm for avoiding data overlapping.

This paper determines if mandated alcohol health information labelling could be an obstacle to international trade by discussing international trade rules affecting member nations. WTO members could use alcohol labelling rules to protect human health, reduce the consumption of alcohol and provide product information. When a member uses alcohol labelling as a technical regulation or standard, it should comply with TBT Articles 2.2 and 2.4. If a member uses some specific warning messages for their objectives, it should be considered the contribution of the measure, trade restrictiveness, and alternatives. If WTO members want to employ their own alcohol labelling schemes for addressing carcinogenicity, intoxicating effects, dependence potential, effects on children, adolescents and pregnancy, it could be a technical barrier and also create adverse effects on international trade. Therefore, the harms of alcohol are supported by scientific evidence, and for this reason, the international harmonization for alcohol labelling should be discussed openly to prevent negative effects on trade.
