This paper investigates ordering alternation phenomena in Korean using the dative construction data from Sejong Corpus of Modern Korean (Kim, 2000). The paper first shows that syntactic weight and information structure are distinct and independent factors that influence word order in Korean. Moreover, it reveals that heaviness and givenness compete each other and exert diverging effects on word order, which contrasts the converging effects of these factors shown in word orders of right-branching languages like English. The typological variation of syntactic weight effect poses interesting theoretical and empirical questions, which are discussed in relation to processing efficiency in ordering.

In this paper, we implemented an interface that provides a better food ordering mechanism and enables real-time selection of recipe ingredient ratios for customized food orders from global customers. Providing appropriate food to global customers by arranging a selection of menu on the order system screen that shows the basic ratio of each recipe ingredient and provides a customized recipe ingredient composition ratio by configuring a recipe graph without a system for simply selecting and ordering food menus. By enabling interaction, it allows users to provide customized services through the ratio adjustment of various recipe ingredients in the food menu ordering device

3GPP RLC protocol specification adopted a window-controlled selective-repeat ARQ scheme for provisioning reliable data transmission. Inevitably, the re-ordering issue arises in the 3GPP's ARQ since it belongs to the selective-repeat ARQ clan. A long re-ordering time results in the degradation of throughput and delay performance, and may invoke the overflow of the re-ordering buffer. Also, the re-ordering time must be regulated to meet the requirements of some services which are both loss-sensitive and delay-sensitive. In the 3GPP's ARQ, we may deflate the occupancy of the re-ordering buffer by reducing the window size and/or length of the status report period. Such a decrease, however, deteriorates the throughput and delay performance and encroaches the resource of the reverse channel. Aiming at reducing the occupancy at the re-ordering buffer while suppressing the degradation of throughput and delay performance, we propose threshold-dependent occupancy control schemes, identified as post-threshold and pre-threshold schemes, as supplements to the 3GPP's ARQ. For judging the effectiveness of the proposed schemes, we investigate peak occupancy, maximum throughput and average delay in the practical environment involving fading channels. From the simulation results, we observe that the proposed schemes invoke the performance trade-off between occupancy and throughput in general. Also, we reveal that the post-threshold scheme is able to improve the throughput and delay performance of the ordinary 3GPP's ARQ without inflating the occupancy of the re-ordering buffer.

Many survey data are collected today to measure personal values and to order them according to their importance. There are two popular procedures to achieve the goal: ranking procedures and rating procedures. The ranking procedures can be divided into two categories; full ranking procedures and reduced ranking procedures. The reduced ranking procedure is more often used because of its easiness to respondents. However, the ordered responses are not generally incorporated into ordering their values. This research has studied ways to incorporate the ordered responses into ordering the values. We have considered the ranking scales as the conditional rating scales. Our findings are that the ordering values based on the weighted proportions is better than one based on the unweighted proportions.

As a result of the popularization of smart devices, smart phones or the tablets have become necessities in modern society. In this current of the times, the bring-your-own-device environment, in which personally owned smart devices are utilized in life, is attracting attention. In this context, this paper designed a Wi-Fi remote ordering system focused on the BYOD environment. If the Wi-Fi remote ordering system based on the BYOD environment is popularized, positive effects can be expected such as the enhancement of efficiency and the increase of customer benefits. As a typical example, real-time customer requests via smart devices enable the provision of fast services. This paper designed a mobile app for customers' remote ordering and web pages on which member stores can inquire details of orders, manage a menu, and register statistical data on sales. If the Wi-Fi remote ordering system designed by this paper is widely distributed internationally, it is expected that the system will be used usefully by many people.

This study examined the perception and behavior of fast food restaurant customers toward ordering kiosk nutrition information. Specifically, the influence of nutrition information transparency and information quality on behavioral intention and revisit intention were identified. In addition, the difference in the nutrition information transparency and information quality was analyzed according to the health consciousness of the customers. The study employed a self-administered survey that was distributed both online and offline from November 8~22, 2018. The sample of the study was customers who had experienced ordering from the kiosk in a fast food restaurant in the six months prior to taking the survey. A total of 250 (98.0%) respondents completed the survey, which was used for data analysis. As a result, there was a significant relation between transparency and nutrition information quality (P<0.001). The higher the visibility and inferability of the nutrition information, the better the nutrition information quality. Nutrition information quality has a significant impact on the levels of customer satisfaction and revisit intention (P<0.001). For the differences in the transparency and nutrition information quality by health consciousness of customers, the results indicated that groups with high health consciousness (3.74 or higher) perceived a higher transparency and nutritional information quality than those with a lower health consciousness. These findings can form the basis of a strategy in developing nutrition information of ordering kiosks in restaurants. In addition, it can be applied to academia and industry.

A variety of different metrics has been introduced to measure the similarity of two given sequences. These widely used metrics are ranging from spell correctors and categorizers to new sequence mining applications. Different metrics consider different aspects of sequences, but the essence of any sequence is extracted from the ordering of its elements. In this paper, we propose a novel sequence similarity measure that is based on all ordered pairs of one sequence and where a Hasse diagram is built in the other sequence. In contrast with existing approaches, the idea behind the proposed sequence similarity metric is to extract all ordering features to capture sequence properties. We designed a clustering problem to evaluate our sequence similarity metric. Experimental results showed the superiority of our proposed sequence similarity metric in maximizing the purity of clustering compared to metrics such as d2, Smith-Waterman, Levenshtein, and Needleman-Wunsch. The limitation of those methods originates from some neglected sequence features, which are considered in our proposed sequence similarity metric.

For multivariate distributions satisfying stochastic ordering, we suggest maximum likelihood estimation with incomplete data via an EM algorithm. In this paper we restrict our attention to the contingency tables with partially cross-classified observations. We may use the existing isotonic regression program to implement EM algorithm, and we illustrate the estimation process through an example.

The most important thing in the garments enterprises is fast reaction. Expecially in the China has both many population and large territory, so each region of China, for instance, northeast, northwest, huanan, huabei, has various climate and considerably different temperature. As a result China garments enterprises require different clothes at the same time. This study build a reliable market-response process as a sub module of SCM that lay emphasis on production and sale cope with specific character of China. This process build a information chain including manufacture-planning, manufacture-ordering, production, arrivals of goods, distribution, sale, sale-evaluation, cross shipment, supplement shipment, and ordering popular goods and similar products. As a result of those, the focused points of this process are real time data gathering and various analysis of data, so it can be possible supporting more faster and more accurate market decision making system and our proposed goal is accomplishment of management profit.

In this paper, we shall convey preservation of some partial orderings and closures of some positive ageing classes under k-out-of-n systems of like components. That is, if the life time of a component A is larger than that of a component B in any of the NBU, DMRL, NBUE, HNBUE, NBUFR and NBUFRA orderings, then a k-out-of-n system formed by i.i.d.. components of type A has larger life time, in that ordering, than that of a similar system consisting of n i.i.d. components type of B. And using these partial orderings, closures of positive aging classes(NBU, DMRL, NBUE, HNBUE, NBUFR and NBUFRA) under the coherent system like components.
