The ZEB certification system has come into effect since 2018 according to the ZEB road map. From 2020, the public buildings with the total floor area smaller than $3000m^2$ are the target of the certification, and it will be extended to the buildings with up to $5000m^2$ floor area in 2025. However, current mandatory regulations for public office buildings seem already to meet the ZEB certification system planned for 2025. In this work, two buildings belong to $3,000{\sim}5,000m^2$ in total floor area were selected to analyze the possibility of meeting the ZEB certification only by following current obligation regulations. Results showed that the test buildings satisfied the minimum building energy efficiency and energy self-sufficiency rates for the ZEB certification when the mandatory insulation and installation ratio of renewable energy are applied. This can be useful for revising the road map or extending the target buildings of the ZEB certification.

Many countries have run their own certification systems in order to reduce the environmental loads from buildings. Domestically, various systems are applied according to building types from Building Energy Efficiency Rating System since 2001 to Green Home Construction Standard and Performance since 2009. However, these systems provide the applicants with confusion and waste by exposing them to several systems simultaneously, some of which are mandatory. Therefore, this study aims to ensure the flexibility among those systems and eliminate the possible waste by suggesting mutual accreditation method of evaluation results. To achieve this purpose, firstly, the thirteen similar evaluation items are identified between Housing Performance Grading Indication System and Green Building Rating System. Then, the mutual accreditation method is developed by comparing detailed evaluation criteria and credits for those thirteen items.

Purpose: This study aimed to suggest strategies for advancing local-government-based accreditation systems and surveyor training in long-term care facilities in Korea. Methods: A comprehensive review of the literature including research papers and official reports issued by governments from the United States, Australia, and Japan was conducted to explore domestic and international policies related to long-term care facility certification and accreditation systems. Results: The USA has two types of care quality assurance systems including mandatory certification (5-star rating system) by the Centers for Medicare and Medicaid Services and voluntary accreditation by the Joint Commission on Accreditation of Healthcare Organizations. Australia operates a government-based mandatory accreditation system for all long-term care facilities through the Australian Aged Care Quality Agency. Japan, particularly the Tokyo district, operates a third-party evaluation system that involves the voluntary participation of long-term care facilities. Conclusion: This study provides several strategies to enhance accreditation processes and surveyors'expertise. For instance, motivating facilities to voluntarily participate in accreditation is necessary by 1) providing sufficient and continuous consultations and feedback about how to improve care quality, 2) differentiating accreditation domains and indicators from the national health insurance certification system, and 3) actively utilizing accreditation results and providing incentives.

A task in imprecise computation consists of mandatory part and optional part. The optional part can be executed partially and the quality of service is measured by the amount of the execution. Many paper showed that multimedia systems are good applications of imprecise computation. It is important to guarantee QoS which is a critical factor in multimedia systems. Previous works didn't consider QoS and processor slack were assigned randomly to tasks. This paper presented a systemic slack assignment method according to QoS levels of tasks. A simulation result showed that our method can be a good choice for multimedia systems with QoS requirement.

As a result of analyzing the domestic and foreign HACCP systems, advanced countries mandated HACCP system on all foods to strengthen food safety management and USA, EU and China do not apply small-scale HACCP system. Looking at the cases of food safety accidents in Korea and the non-compliance rate of HACCP certification evaluation by size, the accident rate of companies without HACCP certification was 31.2% higher than that of companies with HACCP certification. The nonconformity rate of food inspection standards was analyzed to be 89.0% higher than that of HACCP certification companies. Based on the international trend of food safety management and the frequency of food safety accidents, it is proposed to gradually expand the mandatory application of HACCP system in Korea to all foods, and to change the small-scale HACCP standard from less than 500 million Korean won or 21 employees to less than 500 million Korean won.

Purpose: The purpose of this research was to investigate the spread pattern of Korean legal certification systems and their impact on industry performance. Methods: It first analyzes the life cycle of legal certification systems and classifies them into four categories based on the spread patterns in a chronological view. A survey study is then conducted to find out the impact of legal certification systems on financial performance. Both the legal mandatory certification systems and the legal voluntary certification systems are included in the survey. Results: Four spread patterns of legal certification systems are sustainable growth, stagnation after growth, decrease after growth, and repetition of growth and declination. 56% of 293 certified corporations responded positively about the financial impact of their certification systems. Conclusion: The policy makers can utilize the results of this study in designing additional certification systems as well as promoting the current legal certification systems.

The primary purpose of security mechanisms in a computer systems is to control the access to information. There are two types of access control mechanisms to be used typically. One is discretionary access control(DAC) and another is mandatory access control(MAC). In this study an access control mechanism is introduced for secure access path in security system. The security policy of this access control is that no disclosure of information and no unauthorized modification of information. To make this access control correspond to security policy, we introduce three properties; read, write and create.

IT security companies have been releasing file system filter driver security solutions based on the whitelist, which are being used by several enterprises in the relevant industries. However, in February 2019, a whitelist vulnerability was discovered in Microsoft Edge browser, which allows malicious code to be executed unknown to users. If a hacker had inserted a program that executed malicious code into the whitelist, it would have resulted in considerable damage. File system filter driver security solutions based on the whitelist are discretionary access control (DAC) models. Hence, the whitelist is vulnerable because it only considers the target subject to be accessed, without taking into account the access rights of the file target object. In this study, we propose an industrial device security system for Windows to address this vulnerability, which improves the security of the security policy by determining not only the access rights of the subject but also those of the object through the application of the mandatory access control (MAC) policy in the Windows industrial operating system. The access control method does not base the security policy on the whitelist; instead, by investigating the setting of the security policy not only for the subject but also the object, we propose a method that provides improved stability, compared to the conventional whitelist method.

Bibliographical Description for Revolutionary Historical Archives is created to describe records at the item level. It defines descriptive elements, punctuations, formats and methods. Descriptive elements are composed of 20 elements, each of which is either mandatory or optional. Mandatory elements are: repositories codes, documents codes, dates, creators, title, classification codes, and subject vocabularies. Abstracts were previously included in card cataloging and are removed in the computerized system. New elements, such as "uncontrolled vocabularies," "name of places," "personal names," "organizational structures" and "meetings," are added to allow keyword search. Considering that subject vocabulary searches are the most important in computerized systems, however, Guidelines for the Subject Indexing for Revolutionary Historical Archives as well as Subject Headings, as a result from the Guidelines, are created. The most extraordinary features in Chinese archival description are said to be the Guidelines for the Classification Indexing for Revolutionary Historical Archives and Materials as well as the Classification Scheme, both of which are created to allow subject search of records content. It is because Chinese practice of records management distinguishes the classification for arrangement from that for retrieval. Chinese archival description is, therefore, composed of bibliographic description rules, subject headings, and the classification scheme for retrieval.
