The manufacturing paradigm has shifted dramatically over the past decade from “push” or mass production mode to “pull” or customer-driven, order-based manufacturing mode, as multitudes of customers now demand mass customization of configurable products. As a means to achieve such rapidly responsive manufacturing system, Advanced Planning System (APS) has become an essential software tool for achieving modern “build-to-order” and “configure-to-order” manufacturing environment. APS enables manufacturers to respond to variety of customer demands In real time by instantly configuring manufacturing processes based on specifications described in each purchase orders and providing capable-to-promise information directly to customer by performing rapid “what-if” manufacturing simulated scenarios. This paper discusses the working of such system as well as the business processes that incorporate such systems to enable efficient “build-to-order” environment.

In a robust regression model, it is typically assumed that the errors are normally distributed. However, what if the error distribution is deviated from the normality and the response variables are not completely observable due to censoring? For complete data, Kim and Lai(1998) suggested a new adaptive M-estimator with an asymptotically efficient score function. The adaptive M-estimator is based on using B-splines to estimate the score function and simple cross validation to determine the knots of the B-splines, which are a modified version of Kun( 1992). We herein extend this method to right-censored data and study how well the adaptive M-estimator performs for various error distributions and censoring rates. Some impressive simulation results are shown.

In his recent paper, Hanseung Kim (2014) discusses the Cable Guy paradox and argues that given the nature of regret, it is rational to bet on the cable guy's afternoon arrival, though it is equally probable for him to arrive in the morning or afternoon interval. In this paper, I argue that regret is not essential to the paradox in that the paradox still arises even if we ignore regret. I then briefly discuss a possible way to proceed to resolve the paradox.

This study investigates what criterion airline customers recognize important when evaluating airline firms. Specifically it is surveyed if different criterion are used by different groups of airline customers when choosing an airline firm. In addition customer group with high loyalty to 'K' airline, national carrier of Korea, is differently evaluate 'K' airline for the selection criterion over customer group without loyalty. Frequent flyer program is suggested most important by most of the customers being followed by flight schedule. Flight schedule, in-flight food and air fare of 'K' airline are differently evaluated according to level of royalty to the airline. However there appears no difference in the evaluation of seat and entertainment between two groups, customers with high loyalty and customers without loyalty.

Since Perlmutter (1978) proposed the Unaccusativity Hypothesis, the past two decades have seen a flourish of studies investigating the potential validity of unaccusativity in Korean. The central contentious issues have been whether unaccusativity can also be assumed in Korean, and, if so, what criteria could be proposed to discern the unaccusativity among various predicates. In this paper, several suggestions made theoretically and experimentally to address the semantic and/or syntactic distinction of the two types of Korean intransitive predicates are critically reviewed and evaluated from the standpoint that there is a close correlation between syntax and lexical semantics of intransitives. It is proposed, then, that the Korean unaccusativity can be reliably differentiated through the combined semantic criteria of [${\pm}$agentive] and [${\pm}$active]. In addition, case alternations in long form negation constructions are shown to be the most reliable and valid syntactic criteria for testing Korean unaccusatives.

This paper, introduces a Stochastic Project Scheduling Simulation system (SPSS III) developed by the author to predict a project completion probability in a certain time. The system integrates deterministic CPM, probabilistic PERT, and stochastic Discrete Event Simulation (DES) scheduling methods into one system. It implements automated statistical analysis methods for computing the minimum number of simulation runs, the significance of the difference between independent simulations, and the confidence interval for the mean project duration as well as sensitivity analysis method in What-if analyzer component. The SPSS 111 gives the several benefits to researchers in that it (1) complements PERT and Monte Carlo simulation by using stochastic activity durations via a web based JAVA simulation over the Internet, (2) provides a way to model a project network having different probability distribution functions, (3) implements statistical analyses method which enable to produce a reliable prediction of the probability of completing a project in a specified time, and (4) allows researchers to compare the outcome of CPM, PERT and DES under different variability or skewness in the activity duration data.

Have elderly parents parted with parental role after the children were grown up? If they still have, what kinds and degrees of parental responsibilities endured? Do they actively perform the role? Do they satisfy to engage in parenting? The main purpose of present study explored these questions conceming rural old-aged families using data of 143 elderly parents aged 60 years and above. The results indicate that elderly parents perceived parenting adult children to be very important, regarding themselves as househeads to teach family members how to integrate together. The results also demonstrate that elderly parents performed parental role actively in teaching family rituals and providing emotional support. The elderly parents also report that they were fairly satisfied with involvement in adult children's lives. Our findings suggest that further in-depth research is required in eliciting the role parameters of elderly parents based on our social and cultural changes. In addition, it is encouraged to examine the adult children's expectation of their elderly parents for renegotiating and restructuring parent-child relationships when both are adults.

This research explores the intension of repeatable guests through on the wedding facilities, employees' service ability, and banquet menu. First, wedding facilities include transportation, parking lots, subsidiary facilities, reception desks, Paebaek Rooms, and waiting rooms for brides. Secondly, according to the analysis for service quality of hotel wedding feasts, respondence and sympathy were not be fully considered while good effects showed through materiality, reliability and conviction. Thirdly, hotels will be expected to have re-visiting guests when the guests have good experience on the hotel facilities and satisfying menu. Alternatively, menu would have a negative result if there's not satisfying service. Employees should be aware of the list of menu and can be able to offer a suggestion. In other words, a banquet has to be prepared not only with fresh or seasoned ingredients but with good service to make the guests revisit. Therefore, we should be aware of what our guests want and how to prepare for their satisfaction.

Professor Daihyun Chung has recently presented an intriguing view of Ban-mal(non-honorific expressions) in Korean. He criticizes uses of Ban-mal, on the grounds that they presuppose the existence of hierarchical structures in human beings. Professor Chung also advocates ″a relational theory of Ban-mal″ according to which ascriptions of 'n-mal' should be relativized to the speaker-hearer relationship. He employs this view in showing that uses of Ban-mal indeed presuppose the existence of hierarchical structures in human beings I claim that Professor Chung has not shown the credibility of his relational theory of Ban-mal, and that this very view leads to an unintended and undesirable consequence. Moreover, 1 show that even if we assume that this view is true for the sake of an argument, he is not able to show that uses of Ban-mal indeed presuppose the existence of hierarchical structures. All he can show is rather that uses of 'Ban-mal'(a meta-linguistic expression) presuppose the existence of hierarchical structures. Finally, 1 conclude that what really presupposes the existence of hierarchical structures is the asymmetrical uses of Ban-mal and honorific expressions.

Korean infants' use of gesture was examined with 45 10-to 17-month olds. The mothers of infants were asked to check each word in the MacArthur Communicative Development Inventory-Korean (MCDI-K) vocabulary checklist if their infant had a gesture for a given word and to indicate what kind of early communicative behavior she showed in 5 different situations. The results show that infants in this study have 11 gestures, of which many are learned within the context of routines or games. Referential gestures were rarely reported. There was no positive correlation between the number of gestures and the number of expressive words. However, more qualitative measures on early communicative behaviors show that there was a positive correlation between "frequent use of gestures" and "try to communicate by verbal means".
