With the recent advancement of information and communication technologies such as artificial intelligence, big data, cloud computing, and 5G, data is being produced and digitized in unprecedented amounts. As a result, data has emerged as a critical resource for the future economy, and overseas countries have been revising laws for data protection and utilization. In Korea, the 'Data 3 Act' was revised in 2020 to introduce institutional measures that classify personal information, pseudonymized information, and anonymous information for research, statistics, and preservation of public records. Among them, it is expected to increase the added value of data by combining pseudonymized personal information, and to this end, "the Expert Data Combination Agency" and "the Expert Data Agency" (hereinafter referred to as the Expert Data Processing Agency) system were introduced. In comparison to these domestic systems, we would like to analyze similar overseas systems, and it was recently confirmed that the Vermont government in the United States enacted the first "Data Broker Act" in the United States as a measure to protect personal information held by data brokers. In this study, we aim to compare and analyze the roles and functions of the "Expert Data Processing Agency" and "Data Broker," and to identify differences in designated standards, security measures, etc., in order to present ways to contribute to the activation of the data economy and enhance information protection.

Specialized hearing tests for pets are currently in demand. A brainstem auditory evoked response (BAER) test is an objective, non-invasive, and practical electrophysiological method that records electric signals from the peripheral auditory system to the brainstem when an auditory stimulation is provided. In veterinary medicine, sedation or anesthesia is essential for a successful examination. In human medicine, research has established the indications for various sedatives, anesthetics, and drugs according to the depth of anesthesia required. However, in veterinary medicine, there are very few comparative studies on propofol or isoflurane, which are the most common anesthetics used. Therefore, the present study aimed to analyze the difference in BAER test results between sedation with medetomidine, anesthesia using propofol, and inhalation anesthesia with isoflurane after propofol administration. The test was conducted on four healthy adult dogs. There was no statistically significant difference in latency, interpeak latency, or amplitude between the various drugs. The results suggest that a sedative or anesthetic for the administration of a BAER test can be selected according to the patient's needs.

This paper studied the effect of soil-structure interaction (SSI) on the seismic response and retrofit of a reinforced concrete structure with a soft-first story for different soil types. A 5-story structure built on a 30m deep homogeneous soil mass was considered as a case study structure, and steel column jacketing and steel bracing were chosen as seismic retrofit methods. Seismic responses of a fixed-base and a flexible base structure subjected to seven scaled earthquake records were obtained using the software OpenSees to investigate the effect of soil on seismic response and retrofit. The nonlinearBeamColumn elements with the fiber sections were used to simulate the nonlinear behavior of the beams and columns. Soil properties were defined based on shear wave velocity according to categorized site classes defined in ASCE-7. The finite element model of the soil was made using isoparametric four-noded quadrilateral elements and the nonlinear dynamic responses of the combined system of soil and structure were calculated in the OpenSees. The analysis results indicate that the soil-structure interaction plays an important role in the seismic performance and retrofit of a structure with a soft-first story. It was observed that column steel jacketing was effective in the retrofit of the model structure on a fixed base, whereas stronger retrofit measures such as steel bracing were needed when soil-structure interaction was considered.

Safety accidents are of concern during construction projects, even given the recent innovations in digital technologies. These projects remain focused on overcoming specific and limited applications on construction sites. For this reason, the development of an inclusive safety management system has become crucial. This study aims to build a Big Data platform to inform decisions on how to proactively eliminate worker hazards on construction sites. The platform consists of about 100,000 real records and a real-time monitored database featuring various safety indices, such as workers' altitudes, heart rates, and fatigability during construction, which are determined through various wearable devices. The data types are customized and integrated by a research team in accordance with the characteristics of a specific project using hypertext transfer protocol (HTTP). The results can be helpful as efficient tools to ensure successful safety management in complex construction situations. This study is expected to provide three significant contributions to the field, including real-time fatigability analysis and tracking of workers on-site; providing early GPS-based warnings to workers who might be accessing dangerous spaces or places; and monitoring the workers' health indices, based on details from 100,000 cases.

Purpose: This study investigated weight status in survivors of childhood acute lymphocytic leukemia (ALL) and identified related factors. Methods: A retrospective review of the electronic medical records of survivors of childhood ALL (n=230) was conducted. We analyzed the survivors' characteristics, including sex, age, weight status at diagnosis, central nervous system involvement, risk classification, length of treatment, radiation therapy, and hematopoietic stem cell transplantation. Analysis of variance and the chi-squared test were applied to investigate influencing factors. Results: The weight status distribution was as follows: 23 individuals (10.0%) were classified as underweight, 151 individuals (65.7%) were healthy weight, and 56 individuals (24.3%) were overweight/obese. Age at diagnosis (F=10.03, p<.001), weight status at diagnosis (x²=43.41, p<.001), and risk classification (F=10.98, p=0.027) showed significant differences among the weight status groups. Survivors who were older at diagnosis and those in the very high-risk category had a higher likelihood of experiencing underweight status during their survivorship, while survivors who were overweight/obese at diagnosis were more likely to remain overweight/obese at the time of survival. Conclusion: Considering the potential health implications related to an unhealthy weight status in survivors of ALL, it is imperative to undertake early identification and implement interventions for at-risk individuals.

This study examines the seismic vulnerability of vertically irregular reinforced concrete (RC) frame buildings, focusing on the effectiveness of retrofitting techniques such as rocking walls (RWs) in mitigating soft story mechanisms. Utilizing a seven-story residential apartment as a prototype in a high-seismicity urban area, this research performs detailed nonlinear simulations to evaluate both regular and irregular structures, both before and after retrofitting. Pushover and nonlinear time history analyses were conducted using OpenSees software, with a suite of nine ground motion records to capture diverse seismic scenarios. The findings indicate that retrofitting with RWs significantly improves seismic performance: for instance, roof displacements at the Collapse Prevention (CP) level decreased by up to 23% in the irregular structure with retrofitting compared to its non-retrofitted counterpart. Additionally, interstory drift ratios were more uniform post-retrofit, with Drift Concentration Factor (DCF) values approaching 1.0 across all performance levels, reflecting reduced variability in seismic response. The global ductility of the retrofitted buildings improved, with displacement ductility ratios increasing by up to 29%. These results underscore the effectiveness of RWs in enhancing global ductility, mitigating soft story failures, and providing a more predictable deformation pattern during seismic events. The study thus provides valuable insights into the robustness and cost-effectiveness of using rocking walls for retrofitting irregular RC buildings.

This study was made with 1394 clinical records obtained by a mobile charity health team in a rural Korea for 10 days from July 23 to Aug. 1, 1977 to see the disease pattern of the rural population in Korea. The health team consisted of 7 physicians in different clinical departments of the St. Mary's Hospital tried to cover as many as patients in that area by giving full informations and instructions before starting health services. which supposed to minimize the omissions of patients visits in that area. The proportion of each disease as well as its order in terms of the number of patients was reviewed by matching with age and sex distribution of patients, and with the duration of illness (complaints). Major findings obtained in this analysis were as follows; 1. Among 1394 patients, 536 (38.5%) was male and 858(61.5%) was female. As to the age distribution of the patients. those who are in the age group of 10-19 showed the highest proportion of 15.6% and those who are in the age group of 5-9 and 40-49 was the next with the proportion of 15.4% and 15.2% respectively. 2. The most prevalent cause of general morbidity were diseases of digestive system, diseases of nervous system and sensory organs, diseases of respiratory system, and diseases of skin and subcutaneous tissue in order. And their proportions among all patients were 21.8%, 20.7%, 14.5%, and 12.4% in respectively. The order of the diseases ranked by the number of patiens was slightly different in female population from that of total population, i. e. diseases of nervous system and sensory organs was the first. diseases of digestive system was the second, and the diseases of circulatory system was the third. 3. 23.2% of all patients were found to have had symptoms relating to their illness for more or less 5 years, and 18.3%, for more or less 6 months. Looking at the duration of illness by diseases, 28.6% of digestive tract disease patients and had the relating symptoms for about 1 week while 24.3% had had the symptoms for about 5 years, and in diseases of nervous system and and sensory organs, many(33.7%) had had symptoms for relatively long period (more than one year). On the other hand, in diseases of respiratory system, those who had had the relating symptoms for about 1 month was 24.3 % among all patients in this category and those who had had the symptoms for less than 1 week was 32.2%. 4. The duration of illness (complaints) was longer in females than in males and shorter in younger age groups than in older age groups.

Most of the taxes in Korea are collected using a voluntary reporting payment system that meets most financial requirements. However, many people are unaware of their tax liability, and legal forces to ensure payment of taxes are weak within the Korean social structure. Therefore, the tax system cannot depend only on people's awareness of their tax liability, and for these reasons the Korean government has been investigating a system for fair taxation and the administrative punishment for tax evasion. In addition, an improvement to the taxation system is strongly 'demanded in order to protect taxpayers' rights, and improve the efficiency and rationality of the system. In this study, I compare and analyze the problems related to each nation's tax investigation system, and then propose an improved plan for a tax investigation system in Korea. It is necessary to prescribe in the bylaws of the Office of National Taxation that the investigator's performance rating or incentives are not affected in any way by the tax investigator's actual records on tax collection, as this type of evaluation can easily lead to conflicts with the primary goals of the law or written constitution.
