  • OOXML-based MS-Office digital files are extensively utilized by businesses and organizations worldwide. However, OOXML-based MS-Office digital files are vulnerable to forgery and corruption attack by including hidden suspicious information, which can lead to activating malware or shell code being hidden in the file. Such malicious code can cause a computer system to malfunction or become infected with ransomware. To prevent such attacks, it is necessary to analyze and detect the corruption of OOXML-based MS-Office files. In this paper, we examine the weaknesses of the existing OOXML-based MS-Office file structure and analyzes how concealment and forgery are performed on MS-Office digital files. As a result, we propose a system to detect hidden data effectively and proactively respond to ransomware attacks exploiting MS-Office security vulnerabilities. Proposed system is designed to provide reliable and efficient detection of hidden data in OOXML-based MS-Office files, which can help organizations protect against potential security threats.

  • This is a study on the status of color scheme of domestic office furniture. In order to pursue the planned and effective usage of color on office furniture, we investigate and analyze the status of used color based on products from four domestic office furniture companies. Once we review the definition and characteristics of office furniture, we theoretically investigate the importance of correct color planning and psychological effect based on the psychological theory as research methods. In addition, objective condition of color analysis is presented by clearly stating the color measurement which is used in this study and the NCS as analysis standards, and status of the usage of color is investigated and analyzed based on representative products from four domestic office furniture companies. Results showed that only five products which are 26.3% out of 19 products from four companies achieved a good balance based on both color harmony theories. We hope that studies to recognize the importance of usage of correct color on the office furniture, to improve the office environment and to increase the efficiency of work will be conducted continuously.

  • There has been an exponential increase in plastic surgery cases over the last 20 years, surging from 2.8 million to 17.5 million cases per year. Seventy-two percent of these cases are being performed in the office-based or ambulatory setting. There are certain advantages to performing aesthetic procedures in the office, but several widely publicized fatalities and malpractice claims has put the spotlight on patient safety and the lack of uniform regulation of office-based practices. While 33 states currently have legislation for office-based surgery and anesthesia, 17 states have no mandate to report patient deaths or adverse outcomes. The literature on office-base surgery and anesthesia has demonstrated significant improvements in patient safety over the last 20 years. In the following review of the proceedings from the PRS Korea 2018 meeting, we discuss several key concepts regarding safe anesthesia for office-based cosmetic surgery. These include the safe delivery of oxygen, appropriate local anesthetic usage and the avoidance of local anesthetic toxicity, the implementation of Enhanced Recovery after Surgery protocols, multimodal analgesic techniques with less reliance on narcotic pain medications, the use of surgical safety checklists, and incorporating "the patient" into the surgical decision-making process through decision aids.

  • Korean government had introduced copayment system as cost sharing to office-based medical care in order to reduce the demand for care in 1986. This review focuses on trends and characteristics of copayment on office-based medical care from 1991 to the end of Jan. 2001. Objectives of this study is ${\circled}1$ to analyse historical trends of copayment on office-based medical care during the last decade, ${\circled}2$ to analyse the effect of copayment introduced to office-based medical care on NHI finance, ${\circled}3$ to analyse the changing trends of the size of copayment in utilizing office-based medical care for the past 10 years, ${\circled}4$ to evaluate the meaning of copayment alteration implemented after the introduction of new prescription system and finally ${\circled}5$ to draw a some policy implications from the results of this review. We found that the main purpose of copayment introduction had been reduction in the expenditure of NHI finance. But, the reduction effect of insurer's expenditure has turned out to be negative and NHI finance has been in crisis after the introduction of new prescription system. Also, the copayment level of the insured has increased actually on a large scale. It seems that the introduction of new prescription system has changed the meanings and its policy implications of copayment system.

  • The pulsed photoangiolytic 532-nm potassium-titanyl-phosphate (KTP) laser has emerged in recent years as an efficacious treatment modality for vocal fold lesions. It also has broadened the indications for other laryngeal laser surgery. Features of KTP laser that it is a fiber-based delivery system and its energy is selectively absorbed by oxyhemoglobin make it suitable for office-based laryngeal procedures. An office-based KTP laser surgery provides an alternative management option for benign laryngeal diseases and can be performed comfortably under flexible endoscopic guidance which is placed through the nose of a fully awake patient. Office-based laryngeal surgery with a KTP laser can alleviate the need for general anesthesia. However, there are some limitations to apply due to reduced visual precision and the fact that the vocal folds are moving during procedures. Clinicians should carefully weigh the advantages and disadvantages of office-based procedures before a treatment option is selected. Patient selection and standardized laser energy parameters may help in decreasing complications and improving the treatment results.
