Development of the KOSHA Proficiency Testing Scheme on Asbestos Analysis in Korea

This commentary presents the regulatory backgrounds and development of the national proficiency testing (PT) scheme on asbestos analysis in the Republic of Korea. Since 2009, under the amended Occupational Safety and Health Act, the survey of asbestos in buildings and clearance test of asbestos removal works have been mandated to be carried out by the laboratories designated by the Ministry of Employment and Labor (MOEL) in the Republic of Korea. To assess the performance of asbestos laboratories, a PT scheme on asbestos analysis was launched by the Korea Occupational Safety and Health Agency (KOSHA) on behalf of the MOEL in 2007. Participating laboratories are evaluated once a year for fiber counting and bulk asbestos analysis by phase contrast microscopy and polarized light microscopy, respectively. Currently, the number of laboratory enrollments is > 200, and the percentage of passed laboratories is > 90. The current status and several significant changes in operation, sample preparations, and statistics of assigning the reference values of the KOSHA PT scheme on asbestos analysis are presented. Critical retrospect based on the experiences of operating the KOSHA PT scheme suggests considerations for developing a new national PT scheme for asbestos analysis.

Diversity of vir Genes in Plasmodium vivax from Endemic Regions in the Republic of Korea: an Initial Evaluation

Variant surface antigens (VSAs) encoded by pir families are considered to be the key proteins used by many Plasmodium spp. to escape the host immune system by antigenic variation. This attribute of VSAs is a critical issue in the development of a novel vaccine. In this regard, a population genetic study of vir genes from Plasmodium vivax was performed in the Republic of Korea (ROK). Eighty-five venous blood samples and 4 of the vir genes, namely vir 27, vir 21, vir 12, and vir 4, were selected for study. The number of segregating sites (S), number of haplotypes (H), haplotype diversity (Hd), DNA diversity (π and Θw), and Tajima’s D test value were conducted. Phylogenetic trees of each gene were constructed. The vir 21 (S=143, H=22, Hd=0.827) was the most genetically diverse gene, and the vir 4 (S=6, H=4, Hd=0.556) was the opposite one. Tajima’s D values for vir 27 (1.08530, P>0.1), vir 12 (2.89007, P0.1) were positive, and that of vir 4 (−1.32162, P>0.1) was negative. All phylogenetic trees showed 2 clades with no particular branching according to the geographical differences and cluster. This study is the first survey on the vir genes in ROK, providing information on the genetic level. The sample sequences from vir 4 showed a clear difference to the Sal-1 reference gene sequence, whereas they were very similar to those from Indian isolates.

Current Human Rights Education for Psychiatrists Leaves Much to Be Desired / 신경정신의학

OBJECTIVES: Human rights education programs have been implemented annually since Korea enacted human rights legislation in 2009. The purpose of this study was to investigate attitudes of Korean psychiatrists toward human rights education and assess the relevance of the provided education materials. METHODS: Questionnaires comprised of 8 items were provided to 274 psychiatrists attending the April 2015 Korean Neuropsychiatric Association seminar. In addition, 12 cases related to education material developed by the Korean National Human Rights Commission were examined to determine whether the material's content was relevant and appropriate for human rights education. RESULTS: Data from 267 psychiatrists that answered all requested questions were included in the analysis. Although respondents in general accepted the beneficial intent of human rights education, the majority of respondents (71.5%) disagreed with the mandatory 4 h of annual human rights education. Approximately half of respondents (49.4%) believed that frequency of such education should be decreased. A substantial percentage of respondents (38.7%) expressed overall dissatisfaction with the education program, and more than half of respondents (55.6%) were skeptical that the current education program could produce a real difference in attitudes toward human rights. The case reviews highlighted several problems. First, all education materials were heavily weighted toward psychiatric hospitalization legal proceedings rather than human rights. Among the 12 cases examined, four were considered inappropriate for human rights education because they were presented as if human rights abuse was synonymous with violation of a law, even if the law was ambiguous. CONCLUSION: The current human rights education program does not meet psychiatrists' expectations. The results of this study suggest there is a need to reconsider the purpose and means of providing human rights education to psychiatrists.

Status of Vivax Malaria in the Republic of Korea

Vivax malaria reemerged in the Republic of Korea in 1993. The number of cases of vivax malaria had increased annually until 2000; however, it has decreased constantly since 2001. During the early years after the reemergence, most of the cases occurred among soldiers especially in the region adjacent to the Demilitarized Zone until 1995; however, since 2001, civilian cases have accounted for approximately a half of total cases, also occurring in the neighbor counties of Seoul. Local transmission within the Republic of Korea was already done before the year of 2000. The current status of vivax malaria appears to be in a subsiding phase; however, continuous attentions are needed to prevent further spreading of malaria.
