Purpose - This study empirically analyzes the effects of provisional anti-dumping duties levied on imports by Korea following anti-dumping investigations. An anti-dumping duty is a legal tool that countries use to impose duties on imports to offset injurious dumping. This study verifies how effective the imposition of a provisional anti-dumping duty is and whether such duties have trade chilling effects on aggregate imports. Specifically, this study examines import trade diversion from named to unnamed countries caused by the imposition of provisional anti-dumping duties. Design/methodology - This empirical analysis employs an econometric model of provisional anti-dumping measures for cases in which Korea imposed final affirmative anti-dumping measures. We construct a monthly panel dataset for each stage of anti-dumping investigation undertaken by Korea for all manufacturing industries during 1995-2013. We illustrate a stage-by-stage analysis of anti-dumping investigations from initiation, preliminary decision, imposition of provisional duty, final affirmative decision, and imposition of final affirmative duty on a monthly basis at the six-digit harmonized system code-level. Findings - For cases in which provisional duties are imposed, the reduction in imports from named countries outweighs the increase in imports from unnamed countries. The substantial reduction in imports from named countries is large enough to offset the import diversion to unnamed countries, suggesting that import diversion in investigations is limited during the investigation period. Therefore, the use of provisional anti-dumping duties in Korea is effective, providing evidence of a chilling effect on aggregate imports. Originality/value - Few studies examine the size of the effects on import trade diversion of the imposition of provisional anti-dumping duties. We contribute to the literature by disentangling separate trade effects for each phase of the anti-dumping investigation process and imposition of provisional duty.

Purpose: This qualitative study was to understand the awareness of epidemiological investigation tasks for nurses who were in charge of coronavirus disease 2019 (COVID-19) epidemiological investigations. Methods: Before data collection, written consent was obtained from 13 participants, and the data were then collected from September 1 to December 31, 2021. Individual interviews were conducted and recorded by video interview using Zoom, and data were transcribed verbatim. Four themes were derived by using the qualitative thematic analysis method. Results: The participants perceived that epidemiological investigations were burdensome but that the field work was important, and that expertise and collaboration were required. The participants started work without preparation due to the explosive increase in the number of confirmed COVID-19 cases, and they recognized work conflicts, unstable employment, and exhaustion as obstacles to their work performance. On the other hand, the participants took pride in contributing to the national epidemiological investigation and control and felt a sense of responsibility as nursing professionals. Finally, participants mentioned that the training of infectious disease practitioner was important for work improvement. Conclusion: Further research is needed on the development of standardized manuals for the training of nursing personnel as infectious disease specialists through the job analysis of epidemiological investigators.

Backgrounds/Aims: Double duct sign (DDS) (dilated common bile and pancreatic duct) is synonymous with pancreatic head/peri-ampullary tumor (PHPAT). There is limited evidence on whether incidental DDS (I-DDS) is associated with an increased risk of malignancy. This study aimed to evaluate 5-year outcomes of I-DDS. Methods: Patients were categorized according to their risk of malignancy. 'Low-risk' patients, including those with I-DDS between 2010 and 2015, were analyzed in this study. The primary outcome was incidence of PHPAT within five years of identification of DDS. Histology results from endoscopic ultrasound-guided biopsy were considered diagnostic. Secondary outcomes were incidence of benign causes, extent of follow-up investigations, and clinical indicators of malignancy in patients with DDS. Results: Among 103 patients with DDS, 20 had I-DDS. Subsequent follow-up of these 20 patients found no patient with PHPAT, two (10%) patients with chronic pancreatitis, and 18 (90%) patients with no cause found. The median follow-up duration for 'low-risk' patients was 7.3 years (range, 6-11 years). The mean number of follow-up investigations per patient was two (range, 0-9). Investigations included computed tomography (n = 27), magnetic resonance cholangiopancreatography (n = 23), endoscopy (n = 16), and ultrasound (n = 14). Patients with jaundice were more likely to have malignancy (p < 0.01). Those with abdominal pain were more likely to have a benign cause (p < 0.01). Hyperbilirubinemia and/or deranged liver enzymes and raised CA19-9 were more likely to be associated with PHPAT (p < 0.01). Conclusions: Patients with I-DDS have a low risk of developing PHPAT within five years.

Purpose: The study aimed to determine data collected during tuberculosis (TB) contact investigations and to evaluate the outcomes of these investigations. Methods: We reviewed medical records for child contacts of patients with culture-positive pulmonary TB aged 19 years or older between August 2012 and July 2014. Results: A total of 116 child contacts were identified for 79 patients with culture-positive pulmonary TB. Of 116 contacts identified, 22% were incompletely screened. Of 90 contacts who completed screening, 42% had negative tuberculin skin test (TST) results, 58% had positive results, and 1% had active pulmonary TB at the time of investigation. Of 50 contacts with TB patients with a negative smear, 50% had positive TST results. Age ${\geq}5$ years (OR 8.3; 95% CI 2.3-30) and male gender (OR 3.9; 95% CI 1.5-9.9) were significantly associated with being incompletely screened. Conclusions: Improvement is needed in the process of contact investigations to ensure that contacts of patients with active pulmonary TB are identified and appropriately screened.

OSINT(Open Source Intelligence), rapidly increasing on the surface web in various forms, can also be used for criminal investigations by using profiling. This technique has become quite common in foreign investigative agencies such as the United States. On the other hand, in Korea, it is not used a lot, and there is a large deviation in the quantity and quality of information acquired according to the experience and knowledge level of investigator. Unlike Bazzell's most well-known model, we designed a Korean-style OSINT-based profiling technique that considers the Korean web environment and provides timeline information, focusing on the improved workflow. The database schema to improve the efficiency of profiling is also presented. Using this, we can obtain search results that guarantee a certain level of quantity and quality. And it can also be used as a standard training course. To increase the effectiveness and efficiency of criminal investigations using this technique, it is necessary to strengthen the legal basis and to introduce automation technologies.

In traditional criminal cases, there is a limit to information collection because information on the subject of investigation is provided only with personal information held by the national organization of legal. Surface web-based OSINT(Open Source Intelligence), including SNS and portal sites that can be searched by general search engines, can be used for meaningful profiling for criminal investigations. The Korean-style OSINT workflow can effectively profile based on OSINT, but in the case of individuals, OSINT that can be collected is limited because it begins with "name", and the reliability is limited, such as collecting information of the persons with the same name. In order to overcome these limitations, this paper defines information related to individuals, i.e., equivalent information, and enables efficient and accurate information collection based on this. Therefore, we present an improved workflow that can extract information related to a specific person, ie., equivalent information, from OSINT. For this purpose, different workflows are presented according to the person's profile. Through this, effective profiling of a person (individuals) is possible, thereby increasing reliability in collecting investigation information. According to this study, in the future, by developing a system that can automate the analysis process of information collected using artificial intelligence technology, it can lay the foundation for the use of OSINT in criminal investigations and contribute to diversification of investigation methods.
