Described in this paper is a design of hardware accelerator for implementing public-key cryptographic protocols (PKCPs) based on Elliptic Curve Cryptography (ECC) and RSA. It supports five elliptic curves (ECs) over GF(p) and three key lengths of RSA that are defined by NIST standard. It was designed to support four point operations over ECs and six modular arithmetic operations, making it suitable for hardware implementation of ECC- and RSA-based PKCPs. In order to achieve small-area implementation, a finite field arithmetic circuit was designed with 32-bit data-path, and it adopted word-based Montgomery multiplication algorithm, the Jacobian coordinate system for EC point operations, and the Fermat's little theorem for modular multiplicative inverse. The hardware operation was verified with FPGA device by implementing EC-DH key exchange protocol and RSA operations. It occupied 20,800 gate equivalents and 28 kbits of RAM at 50 MHz clock frequency with 180-nm CMOS cell library, and 1,503 slices and 2 BRAMs in Virtex-5 FPGA device.

Purpose: The purpose of the present study was to analyze and evaluate prior studies published in Korea on the cardiovascular disease-related quality of life, in order to make recommendations for further research. Methods: A total of 15 studies were selected from four databases(Digital library of Research Information Center for Health, Korea Medical Database, MedRic, and National Assembly Library). The selected studies were analyzed according to criteria, such as diagnosis/operation, used instrument, generic/specific instrument, dimension of quality of life, translation/ back-translation, sample size, reliability, validity, responsiveness, number of items, type of scale, time required, and independent variables. Results: Of the 15 cardiovascular disease-related quality of life studies, approximately half of them were conducted with hypertension or ischemic heart disease patients. All studies asserted that the concept of quality of life had multidimensional attributes. With respect to the questionnaire used for measuring the quality of life, only one study used a cardiovascular disease specific-instrument and most studies did not consider whether or not the validity of their instrument had been established. In addition, when using questionnaires developed in other languages, only one study employed a translation/back-translation technique. The types of variables tested for their influence on quality of life were quite limited. Conclusion: It is recommended to develop a reliability and validity established cardiovascular disease specific-quality of life for Korean patients and to identify associated new variables.

According to article 11 of the Public Records Management Act of Korea, metropolitan city, special self-governing city, province or special self-governing province should establish archival institutions for permanent preservation and management of records. As a result, the establishment and operation of archival institutions in Korea has been increase, but since it is still in the stage of introduction, the mission and role of these archives have not been specified by archives act. Therefore, we need to establish a proper legal basis to support it. To do this, it explores the archives act in China, Russia and Germany in terms of basic operational policy, collection and transfer of records, management of records, and service of records. As a result, the study presents some implications for the archives act for the management of archives in Korea.

With the introduction of COBie (Construction Operation Building Exchange) in BIM technology enabling an automatic transfer of design and construction information to operation and management (O&M) phase, the BIM centric O&M management system development process has been tested on the subject of architectural types of building. However, for now, there is a need to investigate the technical feasibility of COBie application to civil structures including industrial facilities. This study takes both "O&M Guideline for Public Wastewater Treatment Plant" and a real wastewater treatment plant into account for the purpose, in which the latter is intended to supplement the result of the first. The findings are three-folds: (1) COBie, as an asset modeling, is not sufficient enough to encompass commissioning data, (2) more relevant IFC development and family library build-up useful to modeling wastewater treatment plant is imperative, and (3) well-planned coordination and organization of COBie data-set in line with O&M practice will enhance the feasibility of the COBie in industrial facilities. The result could be used for a basis study for COBie application, particularly in industrial facilities.

Analyzing research trends is essential for the sustainable development of a discipline and is important for understanding the value of prior research and laying the groundwork for subsequent research. This study aims to draw implications for the future direction of convergence research on the disclosure of information from various disciplines by comparing and analyzing the trends in disclosure of information research in Korea. For this purpose, we analyzed the publication frequency of information disclosure papers listed in the Korea Citation Index (KCI) from 2002 to 2023 and the publication trend by discipline as a time series. In addition, we compared the keyword relationships and specialized research topics of each discipline by applying network analysis and LDA topic modeling techniques to the names and keywords of papers in law, public administration, and library and information science. As a result of the analysis, the law focuses on legal regulations and policy improvement, public administration focuses on changing social needs and administrative operation methods, and LIS focuses on practical approaches to record management and disclosure of information. Based on this, future research directions include combining policy research in law with social change research in public administration and developing realistic policies and operational guidelines from the practical perspective of LIS. Such convergent research will enable the systematic and efficient implementation of disclosure of information systems, contributing to the guarantee of the public's right to know and the enhancement of state transparency.

Multiprecision squaring is one of the most significant algorithms in the core public key cryptography operation. The aim of this work is to present a new improved squaring algorithm compared with the MIRACL's multi precision squaring algorithm in which the previous work [1] on multiprecision multiplication is implemented. First, previous works on multiprecision multiplication and standard squaring are analyzed. Then, our new Lazy Doubling squaring algorithm is introduced. In MIRACLE library [3], Scott's Carry-Catcher Hybrid multiplication technique [1] is applied to implementation of multiprecision multiplication and squaring. Experimental results of the Carry-Catcher hybrid squaring algorithm and the proposed Lazy Doubling squaring algorithm both of which are tested on Atmega128 CPU show that proposed idea has achieved significant performance improvements. The proposed Lazy Doubling Squaring algorithm reduces addition instructions by the fact $a_0\;{\ast}\;2\;+\;a_1\;{\ast}\;2\;+\;...\;+\;a_{n-1}\;{\ast}\;2\;+\;a_n\;{\ast}\;2\;=\;(a_0\;+\;a_1\;+\;...\;+\;a_{n-1}\;+\;a_n)\;{\ast}\;2$ while the standard squaring algorithm reduces multiplication instructions by the fact $S_{ij}\;=\;x_i\;{\ast}\;x_j\;=\;S_{ij}$. Experimental results show that the proposed squaring method is 25% faster than that in MIRACL.
