  • Purpose: To date most research related to patients with breast cancer has discriminately investigated the status within or after the treatment although the patients demand holistic nursing care from the time of diagnosis. Thus, the purpose of this study was to investigate the trajectory of breast cancer diagnosis and patients' experiences in the pre-treatment period. Method: This qualitative study used qualitative thematic analysis. Nineteen Korean women who were diagnosed with breast cancer within the last 6 month participated in the study. Individualized interviews were conducted with each participant in a cancer center in K city. The interviews were tape-recorded, transcribed, and analyzed using the thematic analysis process. Results: The overriding theme was "the scattered life in an unforeseen swirl", which illustrates the participants' unexpected crisis with confusion and emotional distress. Two subthemes included "falling into an unavoidable journey", and "staggering in a muddle with urgency". The categories were "unexpected probability", "nagging nodularity", "ominous presentiment", "emotional upheaval", "bad thought intrusion", and "a sense of urgency". Conclusion: Patients in the pre-treatment period encountered utter emotional distress and a sense of urgency after being diagnosed breast cancer. Strategies to develop nursing care for patients in this period and nursing implications are discussed.

  • Generally, Urban railway have special characteristics with short distance journey and minimum headway intercity transportation. These days, urban railway operators choose the driverless operation system without driver. On the contrary, Conventional & high speed railway utilize for long distance and high speed running. Because of special conditions of freight railway operation compared with urban railway, operation of conventional & high speed railway is showed very different characteristics. In this paper, We compares different operation scheme of urban railway and conventional & high speed railway and then present condition for train control system based on radio.

  • Purpose: Omni-channel retailing is a new retail phenomenon. Consumers in the omni-channel environment do not rely on one channel but integrate different channels from the same retailers freely during a particular shopping journey. The purpose of this study is to better understand omni-channel shoppers in the fashion retailing context. The present study uses consumer characteristics -- fashion innovativeness, technology innovativeness, and fashion purchase involvement -- as determinants predicting consumers' omni-channel shopping intentions for fashion products. Research design, data, and methodology: Data were collected from 403 U.S. consumers, and the Structural Equation Modeling (SEM) was performed to test proposed hypotheses. The survey for this research consisted of three parts. The first part measured consumer traits in terms of their innovativeness and purchase involvement. The second part was designed to measure consumers' omni-channel shopping intentions, and the third part gathered consumer demographic information. Results: The findings confirmed that fashion innovativeness, technology innovativeness, and fashion purchase involvement positively affected consumers' omni-channel shopping intentions. Conclusions: Fashion retailers should integrate various customer touchpoints and offer mobile-enabled technologies to boost consumer traffic to both online and offline stores. They also need to create a shopping environment that is optimized for customer engagement in various shopping processes and allow them to explore different shopping channel options for best purchase decisions.

  • This study examined adaptational aspects by analyzing culture contents, which use Jeju myth "Chasabonpuri" as a writing material. "Chasabonpuri" has a heroic narration of Ganglim, who becomes the grim reaper by solving the serious problem through a journey to the world beyond. Also, it has a value as an archetypal narration because of its reflection on Korean world view of afterlife. Culture contents, which use "Chasabonpuri" as a writing material, have features of 'accurate reproduction of heroic narration' (Ganglim who becomes the grim reaper), 'tragic conversion of narration through humanization' (The way home), 'extension of narration through merging with traditional and modern elements'(Together with God), 'Unique view of the world that reflects the contemporary trend' (Ghost Messenger).

  • Fully homomorphic encryption is a cryptography system in which coded data can be searched and statistically processed without decryption. Fully homomorphic encryption has accelerated searching speed by minimizing time spent on encryption and decryption. In addition, it is also known to prevent leakage of any data decoded for statistical reasons. Also, it is expected to protect personal information stored in the cloud computing environment which is becoming commercialized. Since the 1970s when fully homomorphic encryption was first introduced, it has been researched to develop the algorithm that satisfy effectiveness and functionality. We will take the reader through a journey of these developments and provide a glimpse of the exciting research directions that lie ahead.

  • In Mash & Murrell, Diplock J said that "there is an implied warranty not merely that they shall be merchantable at the time they are put on the vessel, but that they shall be in such a state that they can endure the normal journey and be in a merchantable condition upon arrival." But in The Mercini Lady, Field J said that "the goods would be of satisfactory quality not only when the goods were delivered on to the vessel but also for a reasonable time thereafter." and "The proposed conditions were not excluded by clause 18. ${\cdots}$ clause 18 was not to be construed as extending to conditions ${\cdots}$". In relation to the problems on validity of the goods conformity clauses in FOB contracts, when considering Lord Wright's comments ("${\cdots}$ hence apt and precise words must be used to exclude it: the words guarantee or warranty are not sufficiently clear.") in Cammell Laird & Co Ltd v Manganese Bronze and Brass, FOB contracts are fundamentally one that seller's duty to deliver the goods is completing at the port of shipment and "principle of party autonomy" in Contract Law, I do not think that the terms implied by section 14 of the SGA and Common Law cannot absolutely excluded by the goods conformity clauses in sale contracts. Therefore, in order to exclude the implied terms, the parties must very clearly spell out this in the relevant clauses.

  • After Dantzig and Rasmer introduced Vehicle Routing Problem in 1959, this field has been studied with numerous approaches so far. Classical Vehicle Routing Problem can be described as a problem of multiple number of homogeneous vehicles sharing a same starting node and having their own routes to meet the needs of demand nodes. After satisfying all the needs, they go back to the starting node. In order to apply the real world problem, this problem had been developed with additional constraints and pick up & delivery model is one of them. To enhance the effectiveness of pick up & delivery, hub became a popular concept, which often helps reducing the overall cost and improving the quality of service. Lots of studies have suggested heuristic methods to realize this problem because it often becomes a NP-hard problem. However, because of this characteristic, there are not many studies solving this problem optimally. If the problem can be solved in polynomial time, optimal solution is the best option. Therefore, this study proposes a new mathematical model to solve this problem optimally, verified by a real world problem. The main improvements of this study compared to real world case are firstly, make drivers visit every nodes once except hub, secondly, make drivers visit every nodes at the right time, and thirdly, make drivers start and end their journey at their own homes.

  • This paper introduces the physical phenomena involved in Direct Contact Heat Exchangers (DCHXs) and also investigates the possibility of applying of EIT(Electrical Impedance Tomography) technique for capturing the images of dispersed phases as they stream through a stagnant body of water. A number of cases are studied where two dimensional cross-sectional static images are given for fictitious and actual masses present in a column of water(saline solution). In most direct contact liquid-liquid heat exchangers, oil or hydrocarbon with a density different(lighter or heavier) from water is normally used as dispersed working fluid. The main difficulty that arises with this arrangement lies in the elucidation of complicated flow field where the dispersed phase fluid tends to change its shape and size constantly during its journey through the other phase(water). This paper presents a number of results with different types of dispersed phases that are immiscible with water. The EIT technique has been employed in this context to test its applicability in capturing the dynamic images of dispersed phases. It shows static images of dispersed phases where dynamic images could be obtained by simply extending the algorithms and strategies employed in the present analysis.

  • The term, travel-time reliability, refers to variations in journey time that travelers cannot predict. The purpose of this paper is to suggest a standard way to measure travel time reliability. A modified buffer time indicator is proposed. The index is represented by the difference between planned and actual travel times based on lognormal type travel time distribution. Using this framework, a constant function for railways and a negative parabola function for roads are discussed. The model developed is applied to the real data of Korean road and rail usages to empirically verify the methodology proposed. In this process, the unit value of travel time reliability for each group is estimated. The result of this research is expected to be helpful of conducting more cautious economic feasibility studies of transport.
