This study explains motivation and purpose of adolescents' game use based on Adler's individual psychology. Through in-depth interviews, it was found that the game is a field to reveal their need for approval in the social community and a means of expressing the attitude toward their life. In addition, need for approval shows a difference in adaptive/maladaptive attitude according to the social interest. This means that the role of peers, parents, and society is important in order for an individual's need for approval to produce social adaptive outcomes. It is necessary to acknowledge the game as an important area of self-actualization in which an adolescent is internalizing social interest and recognizing their self and it is required to switch from an attitude of exclusion, disdain and ignorance to an attitude of openness and tolerance and adaptive intervention.

Objective: This study analyzed the status of the application of trade secrets in MSDSs according to size and type of industry. The contents of the MSDS non-public approval policy are summarized. We suggest proactive improvement requirements related to the operation of the MSDS non-public approval policy. Methods: To review this subject, we selected 153 manufacturers and six importers in such fields as organic chemical production. The trade secrets application status and ratio (%) of MSDSs by industry size and industry classification were investigated. Improvements toward a proactive system related to the operation of the MSDS non-public approval policy under the Occupational Safety and Health Act(OSHA) were summarized. Results and Conclusions: According to the results, the trade secret ratio in MSDSs by industry size was 33% in workplaces with less than 50 employees, 23.1% in workplaces with more than 50 but less than 100 workers, 73% in workplaces with more than 100 workers, and 83.4% in workplaces with 300 or more workers. For the trade secret writing rate for MSDSs by industry, the highest was MOCCP (Manufacture of ink, paint, coating and similar products) at 80.9%. MOC (Manufacture of other chemicals) was the lowest at 16.2%. We propose four proactive efforts to minimize the administrative burden of implementation of the MSDS non-public approval policy. The results of this study can be used as basic data for policy improvements to make more effective use of MSDS.

Purpose: This study aimed to examine the process from occurrence of a hospital nurse's suicide to workers' compensation approval, responses of the parties involved, issues debated during approval deliberations, and significant policy changes resulting from the incident. Methods: We conducted in-depth interviews with involved parties and collected various documents, including newspaper articles, forum proceedings, and the agency report on determination of workers' compensation. Content analysis was performed on the collected data. Results: A Joint Task Force continuously reported its progress and findings through mass media such as newspaper, radio, and TV. These activities exerted pressure on a government agency to conduct an occupational disease review and significantly impacted the workers' compensation approval. The agency recognized associations between the hospital's inadequate nurse training and the suicide but did not confirm the excessive overtime and workplace harassment experienced by the nurse as causes of the suicide. This case's media coverage and impact resulted in a law prohibiting workplace harassment and a hospital system dedicating at least one nurse to training activities. Conclusions: This incident had a significant social impact as the first case of workers' compensation approval for a hospital nurse's suicide. However, the case produced no structural changes in nurses' working conditions such as heavy workloads.

During the election period, many polling agencies survey and distribute the approval ratings for each candidate. In the past, public opinion was expressed through the Internet, mobile SNS, or community, although in the past, people had no choice but to survey the approval rating by relying on opinion polls. Therefore, if the public opinion expressed on the Internet is understood through natural language analysis, it is possible to determine the candidate's approval rate as accurately as the result of the opinion poll. Therefore, this paper proposes a method of inferring the approval rate of candidates during the election period by synthesizing the political comments of users through internet community posting data. In order to analyze the approval rate in the post, I would like to suggest a method for generating the model that has the highest correlation with the actual opinion poll by using the KoBert, KcBert, and KoELECTRA models.

Artificial intelligence (AI) will likely affect various fields of medicine. This article aims to explain the fundamental principles of clinical validation, device approval, and insurance coverage decisions of AI algorithms for medical diagnosis and prediction. Discrimination accuracy of AI algorithms is often evaluated with the Dice similarity coefficient, sensitivity, specificity, and traditional or free-response receiver operating characteristic curves. Calibration accuracy should also be assessed, especially for algorithms that provide probabilities to users. As current AI algorithms have limited generalizability to real-world practice, clinical validation of AI should put it to proper external testing and assisting roles. External testing could adopt diagnostic case-control or diagnostic cohort designs. A diagnostic case-control study evaluates the technical validity/accuracy of AI while the latter tests the clinical validity/accuracy of AI in samples representing target patients in real-world clinical scenarios. Ultimate clinical validation of AI requires evaluations of its impact on patient outcomes, referred to as clinical utility, and for which randomized clinical trials are ideal. Device approval of AI is typically granted with proof of technical validity/accuracy and thus does not intend to directly indicate if AI is beneficial for patient care or if it improves patient outcomes. Neither can it categorically address the issue of limited generalizability of AI. After achieving device approval, it is up to medical professionals to determine if the approved AI algorithms are beneficial for real-world patient care. Insurance coverage decisions generally require a demonstration of clinical utility that the use of AI has improved patient outcomes.

Background: The Food and Drug Administration (FDA), the European Medicines Agency (EMA), and the Ministry of Food and Drug Safety (MFDS) have been implementing the expedited programs that promote the innovative approval of new medications to be used for serious diseases. The authors comprehensively investigated, analyzed, and compared the regulations and guidelines associated with the expedited programs. Methods: The expedited programs for innovative drug development and approval were searched from the homepages of FDA, EMA and MFDS. The detailed information on the regulations and guidelines associated with the programs was comprehensively extracted from various electronic repositories of each regulatory authority. The information on each program was analyzed, categorized, and compared from the points of benefits, applicability with scientific rationale, application procedure, and maintenance. Results: FDA's programs include Fast Track Designation, Breakthrough Therapy Designation, Priority Review Designation, and Accelerated Approval. EMA's regulation implements PRIority MEdicines (PRIME), Accelerated Assessment, Marketing Authorization under Exceptional Circumstances (MAEC), and Conditional Marketing Authorization (CMA). MFDS has a single Expedited Program. These programs are broadly categorized into those that 1) facilitate early and proactive communication with regulatory authorities, 2) shorten the review time after submitting a marketing application, and 3) temporarily approve a marketing authorization under certain conditions. Conclusion: Each expedited program requires a different level and amount of safety and efficacy evidence to be submitted to each regulatory authority. This article will likely provide the comprehensive information on which program provides scientific and regulatory advantages to be taken for innovative medication development.

An institutional review board (IRB) should independently safeguard the right, safety, and well-being of all clinical trial subjects. It should consist of members who are qualified and experienced to review and evaluate the science, medical aspects, and ethics of the proposed trial. They have to pursue continuing efforts to improve the standards of review. The levels of review include the full board review, expedited review, continuing review, or exempt from review, while the levels of decision-making include approval, conditional approval, deferred approval, and disapproval. Investigators must follow the approved protocols and regulations honestly, and it is the IRB's mission to audit clinical trial sites as well.

This paper is to develop a security module for electronic approval systems. Electronic documents are created, transmitted and saved in the company's intranet computer network. Transmitting electronic documents, however, brings us a security problem. Communications among various computer systems are exposed to many security threats. Those threats are eavesdropping, repudiation, replay back etc. The main purpose of this paper is to develop a module which provides the security of electronic documents while they are passed from one place to another This paper applies Multi-Level security to the electronic approval system that guarantees security of electronic documents from many threats. Multi-Level security controls the access to the documents by granting security level to subject users and object electronic documents. To prevent possible replay back attacks, this paper also uses one time password to the system. The security module is composed of client program and server one. The module was developed using Microsoft Visual Basic 6.0 and Microsoft SQL Server 7.0. The code uses Richard Bondi's WCCO(Wiley CryptoAPI COM Objects) library functions which enables Visual Basic to access Microsoft CryptoAPI.
