Immersive virtual reality provides an effective way of visualizing and analyzing various spatial data, such as wireline logs, three-dimensional seismic, and interpreted geologic boundaries, and etc. Although it is a valuable tool for oil and gas exploration, its usage has been limited to a specific area because of its high development costs. This paper describes the development of an immersive virtual reality system, known as CAVE (Cave Automatic Virtual Environment) that maximizes immersiveness with reasonable prices by using general purpose PC and projectors.

Records at closed private universities are simply kept in stacks without the use of records classification systems. However, the systematic management of such records is needed as these are important records that have legal and evidential value during the litigation process. Therefore, this study intends to develop a classification system for recordkeeping at closed private universities aiming to eliminate unnecessary follow-up procedures that may occur because of the absence of a records classification system, and to develop practical tools for managing records at closed universities. To this end, Seonam University, among the 13 transfer records kept by the Korea Advancing Schools Foundation, was selected as the example for this study. The peculiarities of the closing processes and the catalogs of the transfer records were reviewed, and a business function analysis was conducted. Based on the Guidelines for Prescribing Retention Period of University Records by the National Archives and the Ministry of Education, a records classification system for the closed private universities was proposed for the Records Disposition Schedule to handle the uniqueness of closed universities.

A records management agency assessment must reflect the possibility of actual situations including conditions and implementation. Institutional evaluation systems and indicators tools to improve records management. However, the reality is difficult if they are not conducted through the resources and efforts of the organization. The 2017 evaluation system of the National Archives of Korea and the index, which was published in March 2016, are expected to be highly difficult to perform as the frontline field tasks of the institution for a year. It is composed of indices with questionable effectiveness that are difficult to implement on the field. Some of these include the following: three training sessions for more than 10% of all employees, submission of document archive pictures of all schools, submission of the index items of all documents, increasing the utilization level of the standard record management system for the electronic documents that have not been transferred for several years, the transfer of non-electronic documents of all institutions, reclassification of non-disclosed records, etc. It recognizes the fundamental problems of the records management system and the 2017 evaluation indicators that the National Archives has mentioned about operations. As such, now is the time to reflect the years of experience in the field to amass knowledge that will help improve records management.

At the stage of conceptual design of a helicopter, it is a general way using low fidelity analysis methods because of a large number of design calculations and trade-off studies. Determination of empirical parameters used in analysis codes for more practical design, depends on an user's design experiences, which effects on the accuracy and the fidelity of conceptual design results. Thus, more precise and logical method should be required to determine the empirical parameters used in the conceptual design of a helicopter. The present method is to be used not only in verifying the empirical parameters generated by design requirements, but also regenerate them if they contain any errors. Empirical parameters produced by present method were used to design a helicopter with a payload objective and performance constraints of an operating helicopter. As a result, weights and geometries of designed helicopter matched the target value within 5% significance level, proving that the suggested parameter generating method can be useful in the conceptual design of a helicopter.

FORM(Feature-Oriented Reuse Method) is one of representative product line engineering methods. The essence of FORM is the FORM architecture models, which can be reused in the development of multiple products of a software product line. The FORM architecture models, however, have the following problems when applied in practice. First, they are not standardized models like UML(Unified Modeling Language) and therefore they can be constructed only through a specific modeling tool. Second, they do not represent architectural variability explicitly. Instead their variability is only managed through a mapping from a feature model. To address these two problems, we developed at first a method for representing the FORM architecture models using UML, which enables the FORM architecture models to be constructed through various available UML modeling tools. Also, we developed an effective method for representing as well as managing the variability of the FORM architecture models through a mapping from a feature model.

Software globalization is the supporting process of adapting computer software to different country and culture. Most efforts for software globalization have been focused on the development of software implementation techniques or tools. However, global software sold worldwide has different requirements implied by different contexts, and the difference of requirements may derive different architectural design. In this paper, we define such architectural design knowledge as knowledge models and propose a method for developing and using the knowledge models for software globalization. Also we use set-top box middleware systems for digital data broadcast to validate the applicability of the proposed models and methods.

The aim of this study is focused on getting an almost exact solution which is the simplicity and exactness of an axisymmetrically loaded cylindrical shell. This method replaces the finite element method which is a very powerful tool for analysis of any kind of structure which has an arbitrary shape, but is still a numerical analysis. Instead, this study uses the method of distribution of end actions which is a kind of iteration technique to implement the leading matrix method. The distribution and carry-over factors of a cylinder are calculated by the theory of a differential equation of a beam on an elastic foundation. The results are satisfactory when this method is applied to a cylinder that is subjected to a concentrated load and hydrostatic pressure when compared with the BEF analogy separately.

The present study aims at investigating the current usage patterns of Korean Standard Records Management System. The Korean Standard Records Management System has been designed and distributed by the National Archives Korea in order to support records management of public agencies. An email survey has been sent to 4 types of public agencies: central government agencies, provincial governments, provincial education offices as well as city and county offices. While all agencies are included in the survey for the first three types, only two provincial districts are selected for city and county offices, Out of 101 email questionnaires sent, 65 are returned(63.73%). The results show the usage patterns of 240 functionalities aligned to 9 main functions: accession from records creators, preservation, appraisal, accession to the national archives, reference management, access and tracking, retrieval and use, system management as well as freedom of information management by public institutions. Since its launch in 2007, the system has been distributed to 707 public agencies as of late 2014. The problem is that there has been no attempt to evaluate the functionalities and usabilities of the system. Only grievances from those agencies implemented the system have never been ceased. The present study is expected to offer the levelled ground for productive discussion between the national archives and the agencies.
