This article examines the HRD implications of using robotic technology in the workplace. Because existing literature has been primarily about the technical engineering aspects of robotics, it is difficult to understand the socio-cultural perspective about the challenges and potentials of robotization in the workplace. Especially, in order to identify the best organizational support appropriate for working with robots, this article indicates alternative perspective for observing human-robot interaction in the workplace. In addition, this article points out four implications of robotic technology in organizations for practice and research development in HRD. These implications were identified as (1) defining the components of expertise in terms of human-robot interaction, (2) coping with organizational change process resulting from robotic technology, (3) designing appropriate interventions for an organization to effectively assist human-robot interaction, and (4) establishing the code of work ethics in the robotic age. The suggested implications can contribute to shaping conceptual frameworks for further empirical social science research.

Theoretical and experimental techniques to analyze the two-dimensional liquid motion in a tank are discussed. A Lagrangian FEM with a velocity correction procedure is introduced to describe incompressible free surface fluid flow. A mesh rezoning technique is used to prevent strong distortion of finite elements in the Lagrangian description. Model test technique for sloshing tank is developed using a hydraulic type bench tester. The influence of the variation in the exciting frequency and amplitude are observed for various fill depths. The results of theoretical calculations are compared with those of experiments.

The purpose of this study is to extract metadata based on Dublin Core from national construction information DBs, to design XML schema from the extracted metadata and to apply the previous works to integrated information retrieval system. To extract metadata, co-work was performed with librarians in the field of construction information, and. as a result, twelve metadata elements from Dublin Core and one administrative metadata could be extracted. Based on the investigation and analysis of those thirteen metadata elements, XML schema design process was described in detail. finally, the service environments of integrated information retrieval system to which XML schema was applied was introduced. Further study was also provided.

For the almost certainly convergent series $S_n=\sum_{i=1}^nV-i$ of independent random elements in Banach spaces, by investigating tail series laws of large numbers, the rate of convergence of the series $S_n$ to a random variable s is studied in this paper. More specifically, by studying the duality between the limiting behavior of the tail series $T_n=S-S_{n-1}=\sum_{i=n}^{\infty}V-i$ of random variables and that of Banach space valued random elements, an alternative way of proving a result of the previous work, which establishes the equivalence between the tail series weak law of large numbers and a limit law, is provided in a Banach space setting.

This paper proposes a new approach fur the detection of facial feature regions using the characteristic of DCT(discrete cosine transformation) thatconcentrates the energy of an image into lower frequency coefficients. Since the facial features are pertained to relatively high frequency in a face image, the inverse DCT after removing the DCT's coefficients corresponding to the lower frequencies generates the image where the facial feature regions are emphasized. Thus the facial regions can be easily segmented from the inversed image using any differential operator. In the segmented region, facial features can be found using face template. The proposed algorithm has been tested with the image MIT's CBCL DB and the Yale facedatabase B. The experimental results have shown superior performance under the variations of image size and lighting condition.

The BTL project, 4 years since its operation, has benchmarked the PFI Project in Japan and has been introduced. Given the evaluation step to select a preferred bidder, in a technological factor, the basic plans are corrected and complemented, whereas in a price factor, the low price bidding system is being enforced. There is concern that how to select preferred bidders and how to operate project costs during operation and management period may be problematic. Thus, in this study, using the Analytic Hierarchy Process, the method of deciding the pribrity to select preferred bidders in an early stage of the project and the evaluation model to evaluate the validity of BTL project expenses in process of project enforcement are established. Targeting the group. composed of experts who have experiences in the BTL project. Then, the levelling of evaluation factors and grouping have been carried out as following: LCC analysis and disbursement for government including two more detailed factors.

Researches on U-Healthcare service integrating medical information and IT technologies are actively conducted. U-Healthcare service is the next generation's medical paradigm that ensures conveniences to many users so that the society recognizes the importance and attempts for commercialization through various business model are performed. To form such U-Healthcare service market safely, various policies on the social structure should be established through the standard and the medical law to systemize of the medical information led by the governmen. Especially, the government's security policy to ensure the safety for the government leading visualization of U-Healthcare should be firmly established. Firstly, this paper presents U-healthcare Service and policy guideline. Secondly, it analyzes security threatening factors for the safe U-Healthcare service. By classifying the analyzed security threatening factors based on three major elements of the security, Confidentiality, Integrity and Availability of security policy for each element is proposed.

The purpose of this study is to suggest the value and type of online and offline linked advertisement, which is a new advertisement type that emerged with the advent of the 4th industrial revolution. In this study, based on literature research, we understood the marketing method that evolves from "4P (product, price, place, promotion)" to "4C (co-creation, community, conversation, currency)" and extracted derive 4C elements. Based on this, we analyzed what elements of 4C showed online and offline connectivity through the investigation of on and offline linked advertisements. Through the analysis results, online and offline linked advertisements were classified into 4 types and 14 detailed types according to how they were connected to the number of 4C elements. In this paper, as a final result, we verified that 4C elements of marketing that appeared in the era of the 4th Industrial Revolution are represented in advertisements and suggested the typology of advertisements accordingly. This study is expected to contribute to providing new insights to advertisers and researchers who produce and study online and offline advertisements.
