Advanced imaging approaches (computed tomography, CT; magnetic resonance imaging, MRI; $^{18}F$-fluorodeoxyglucose positron emission tomography, FDG PET) have increased roles in cervical cancer staging and management. The recent FIGO (International Federation of Gynecology and Obstetrics) recommendations encouraged applications to assess the clinical extension of tumors rather than relying on clinical examinations and traditional non-cross sectional investigations. MRI appears to be better than CT for primary tumors and adjacent soft tissue involvement in the pelvis. FDG-PET/CT has increased in usage with a particular benefit for whole body evaluation of tumor metabolic activity. The potential benefits of advanced imaging are assisting selection of treatment based upon actual disease extent, to adequately treat a tumor with minimal normal tissue complications, and to predict the treatment outcomes. Furthermore, sophisticated external radiation treatment and brachytherapy absolutely require advanced imaging for target localization and radiation dose calculation.

Although many waterproofing materials and techniques have been developed and applied, there is still a leakage in concrete structures. The main reason for the failure of waterproofing is due to the lack of consideration of the environmental conditions and the inconsistent performance requirement of the waterproofing materials in response to the complexity of the environmental conditions., and materials that are unsuitable to the environment are still being selected for usage due to their low price. Moreover, there is no valid test assessment for waterproofing materials to be used prior to actual application in the construction site. The development of a testing method and apparatus that can evaluate the composite waterproofing method is proposed in this paper and an interpretation method that can analyze the results of the evaluation.

Shipping containers promote rapid development of the transport industry, and generate economic and social value. However, problems often occur due to imbalance in dynamics between exports and imports, container relocation, traffic congestion, and general shipping network designs. So, efficient and cost-effective cargo management has become crucial for the Jeju Island - Mokpo container route (JMCR) in South Korea. Dozens of recent studies reveal that collapsible or foldable containers, may become an innovative solution to problematic issues within the shipping industry. The major purpose of this study is to discuss conditions required for successful commercial application of foldable containers, based on a cost-benefit analysis precisely for the JMCR. Findings reveal usage of foldable containers can be cost-effective, if containers make a "FULL<->EMPTY" route. To the contrary, a "FULL<->FULL" route can drastically increase expenditure. However, economic analysis of actual figures for 2010-2015 indicate that benefits for Mokpo - Jeju direction are significant to cover losses on the Jeju - Mokpo line. Seasonal patterns and mixing percentages of foldable and standard containers on the route, may also produce cost-effective solutions. Sensitivity analysis reveals that benefits from using foldable containers, depend mostly on empty container shares in addition to various extra costs.

Internet banking is one of many services provided by financial institutions that have become very popular with an increasing trend. Due to the increased amount of usage of the service, Internet banking has become a target from adversaries. One of the points that are at risk of an attack is the login process. Therefore, it is necessary to have a security mechanism that can reduce this risk. This research designs and develops a multi-factor authentication protocol, starting from a registration system, which generates authentication factors, to an actual authentication mechanism. These factors can be categorised into two groups: short term and long term. For the authentication protocol, only three messages need to be exchanged between a client and a financial institution's server. Many cryptographic processes are incorporated into the protocol, such as symmetric and asymmetric cryptography, a symmetric key generation process, a method for generating and verifying digital signatures. All of the authentication messages have been proved and analysed by the logic of GNY and the criteria of OWASP-AT-009. Even though there are additional factors of authentication, users do not really feel any extra load on their part, as shown by the satisfactory survey.

The number of the enterprises which utilize network technology has been increasing for solving problems such as productivity improvement, market trend analysis, and material collection for making decision. Especially, the management of equipment and the recovery time reduction when machines break down are very important factors in productivity improvement of the enterprise. Currently, most of the remote trouble diagnosis of equipment using the internet have just one function of transmitting the trouble information to the user. Therefore it does not directly reflect the user's recovery experience or the developer's new recovery methods. If the user's experienced recovery methods or the developer's recovery methods as well as the basic recovery methods are reflected online or on the internet, it makes it possible to recover faster than before. In this paper, we develop a Remote Monitoring Server (RMS) for chip mounters, and make it possible to reduce the recovery time by reflecting the user's experience and developer's new methods in addition to presenting the basic recovery methods. For this, trouble recovery concept will be defined. Based on this, many functions(trouble diagnosis, the presentation of the basic recovery methods, user's and developer's recovery method, counting function of the trouble number of each code, and presentation of usage number of each recovery methods) were developed. By utilizing the reports of the actual results of chip mounter and the notice function of the parts change time, the rate of operation of the chip mounter can be improved.

This study put its major concern in consumer behavior during a purchase of fashion products through the Internet marketing channels. Therefore, it investigated the Internet shopping and tried to find the reasons why clothes shopping through the Internet marketing channels is not popular enough. Then, alternative marketing strategies would be suggested which is accessible from the relationship marketing approach. The study adopted a qualitative research method to implement those purposes. In-depth interviews were conducted with the interviewees who had an experience of buying a fashion merchandise through the Internet or who had such an intention. And the information on stages of decision-making process and actual purchase was obtained by participating in and observing the process. The results revealed stages of decision-making in purchasing a fashion product through the Internet channels, the process of relationship development, and the elements of relationship marketing which affect purchase intention. The elements of relationship marketing to promote a purchase of a clothing product via the Internet marketing channels included convenience; communication and socal experience; sensual information; risk acknowledgement and pursuit for safety; and usage of complexed marketing channels. Based on these, a few strategic points such as remote reality, database of communication basis, strengthening individualized services, and development of complex marketing channels were suggested.

The SERVQUAL scale is based on the gap theory, which indicates the difference between consumers' expectations and their actual performance. In SERVQUAL scale, the expectations are defined as a "feasible ideal point"(ex, An Excellent hospital has up-to-date equipment). But empirical research identified important problems concerning the conceptual definitions of expectations. They suggests the usage of "desired expectations". Desired expectations are defined as the level at which the consumer predict the service that the organization they visited will perform(ex, $\bigcirc\bigcirc$ hospital has up-to-date equipment). The purpose of this study was to compare the feasible ideal point expectations with desired expectations in assessment of consumer expectations using SERVQUAL scale. We developed two types of questionnaires : (1) to measure feasible ideal point expectations, (2) to measure desired expections. Questionnaire were distributed to ambulatory patients who used the medical service. Total 329 patients participated the hosiptal satisfaction questionnaire(167 for feasible ideal point expectations, 162 for desired expectations). The major finding is as follows: (1) the SERVQUAL scale which was computed by the feasible ideal point showed the higher explanatory power in consumer satisfaction ($R^2$=0.26) than the other identified alternatives(desired expectation, $R^2$=0.11) The results of a study suggests that the feasible ideal point were more conceptually suitable to assess of consumer satisfaction using SERVQUAL scale.SERVQUAL scale.

ERP is an essential information system (IS) that many companies are operating on the basis of this solution. Since ERP is a very important system that is used in business operation and provides quantified information about the efficiency and productivity of the business activities, difference of competitiveness between companies that have successfully implemented ERP and those that do not have is very large. According to a survey done by a global consulting firm, far less than half of the companies are evaluated as successfully internalizing ERP into their organizations. Therefore, there is a need for an accurate assessment of ERP usage and an improvement of ERP based on it and the need become to increase largely. However, in reality, there is neither the systematic evaluation methods or any research about this topic. This study proposes a framework for evaluating the routinization of ERP throughout the life cycle of the ERP based on both the literature in the enterprise architecture, ERP lifecycle, ERP success areas, and actual experience of the authors in ERP implementation. The proposed framework intends to satisfy the following functional requirements : 1) the entire lifecycle of ERP should be evaluated; 2) evaluation of ERP should be performed from the enterprise-wide perspective; 3) evaluation should focus on the core activities of the organization; and objective evaluation criteria should be used in the evaluation.
