인터넷은행 환경 조성과 관련하여 금융당국이 발표한 비대면 실명확인 정책은 대면 이상의 정확성을 기하기 위해 다중확인을 원칙으로 하고 있다. 인터넷은행은 기존 인터넷뱅킹과 법적 실체와 사업모델이 다른데, 본인확인 구조로써 인터넷뱅킹의 본인확인 구조를 유지한 채 실명확인만 대면에서 비대면으로 대체하는 것은 최초 가입자에게 불편을 줄 뿐 아니라, 엄격한 대면확인을 거치는 인터넷뱅킹보다 보안위험에 더 노출될 수 있다. 본 연구는 인터넷은행의 서비스 단계를 등급화하고, 등급에 따라 차등화된 서비스등록 및 이용이 이루어지도록 개선된 본인확인 구조를 제안한다. 또한, 인터넷은행에 대해 발생할 수 있는 보안취약점과 공격모델을 수립하고, 각 공격모델에 대한 인증매체의 보안특성과 서비스 단계별 안전성을 분석한 결과 등급에 따라 기존 인터넷뱅킹보다 비슷하거나 더 높은 안전성을 제공하고, 이용자 가입 유도 측면에서 유용함을 확인하였다.

소방용 비상발전기는 화재와 같은 비상상황에서 인명과 재산을 보호하는 소방시설에 비상전원을 공급하는 중요한 시설이다. 이러한 중요성에 따라 비상발전기는 주기적인 부하시험으로 성능과 상태를 확인하여야 한다. 비상발전기의 일반적인 부하시험 방법은 R, L, C 부하로 구성된 Load Bank를 이용하여 시험하고 있다. 최근, 비상발전기의 효율적인 부하시험을 위하여, 시험 중에 발생한 전력을 저장하였다가 전기사업자에게 판매하는 ESS 부하시험장치의 도입이 검토되고 있다. 그러나 리튬이온배터리의 높은 가격으로 인하여, ESS 부하시험장치는 기존의 Load Bank 방식보다 초기투자비가 많이 소요될 수 있어, 상용화가 어려운 실정이다. 하지만, 비상발전기의 부하시험 동안 발전된 전력의 판매를 고려하면, ESS 부하시험장치는 경제적인 사업모델이 될 가능성이 있다. 따라서, 본 논문에서는 ESS 부하시험장치의 정확한 경제성을 평가하기 위하여, ESS 부하시험장치에 충전된 전력의 판매를 고려한 비용요소와 편익요소로 구성된 경제성평가 모델링을 제시한다. 또한, 제시한 모델링을 바탕으로 ESS 부하시험장치와 Load Bank에 대한 투자회수율과 회수년도를 비교 및 분석한 결과, 전력판매를 고려할 경우 ESS 부하시험장치의 상용화가 가능함을 확인하였다.

The present study was performed to compare the mitochondrial genomes between 2 Spirometra tapeworms, Spirometra erinaceieuropaei and Spirometra decipiens (Cestoidea: Diphyllobothriidae), which larval stages are important etiological agents of sparganosis in humans. For each species, the full mitochondrial genome was amplified in 8 overlapping fragments using total genomic DNA purified from a single worm as the template. The mitochondrial genomes were 13,643 bp (S. erinaceieuropaei) and 13,641 bp (S. decipiens) in length and contained 36 genes; 12 protein-coding genes, 2 ribosomal RNA (rRNA, small and large subunits), and 22 transfer RNAs (tRNAs). The 12 protein-coding genes constituted 10,083 bp (S. erinaceieuropaei) and 10,086 bp (S. decipiens) of their respective mitochondrial genomes. The tRNA genes, ranging in length from 56 to 70 bp, were identified based on putative secondary structures such as the typical cloverleaf shape. A total of 23 intergenic sequences, varying from 1 to 204 bp in size, were interspersed in S. erinaceieuropaei (total, 504 bp) and S. decipiens (total, 496 bp) mtDNA. The 12 protein-coding genes of S. erinaceieuropaei and S. decipiens differed by 12.4%, whereas the overall difference in mtDNA sequence between S. erinaceieuropaei and S. decipiens was 12.9%. Thus, from the standpoint of the mitochondrial genome, S. decipiens represents a valid species that can be distinguished from S. erinaceieuropaei.

Intestinal parasitic infections are a public health burden and a major cause of illness in developing countries. The diseases lead to various health threats, including growth retardation and mental health-related disorders, especially in children. We assessed the risk factors for intestinal parasitic infections among children aged 12-59 months residing in Nyamasheke District, Rwanda. A cross-sectional descriptive study was conducted using secondary data from 1,048 children aged 12-59 months whose stool samples were examined for the presence of intestinal parasites and whose results were registered in the laboratory information system in 2020. The prevalence of intestinal parasites in children aged 12-59 months was 53.2%. The dominant parasites were Ascaris lumbricoides (13.1%), followed by Giardia lamblia (10.9%), Entamoeba histolytica (7.9%), Trichuris trichiura (6.5%), hookworms (1.7%), and Taenia species (1.4%). A significant association was observed between intestinal parasites and the literacy of mothers or children's caregivers (odds ratio (OR)=5.09, P<0.001). Children from farming households were 2.8-fold more likely to contract intestinal parasitic infections than those from nonfarming households (OR=2.8, P<0.001). A significant association was also observed between intestinal parasites and food safety (OR=4.9, P<0.001). Intestinal parasitic infections were significantly associated with hand hygiene practices after using the toilet and washing fresh fruits before eating (P<0.001). The information gathered will help public health providers and partners develop control plans in highly endemic areas in Rwanda.

This study tried to identify the job stress characteristics of female bank workers and the relationship between their stress and symptoms associated with musculoskeletal disorders(MSDs). The total number of 587 female bank tellers have been participated in this study. Specifically, questionnaire surveys regarding job stress and MSDs symptoms were conducted. On the basis of the results from the survey using Korean version of job stress questionnaire with 24 questions, stress scores associated with job requirement and job flexibility were relatively high. The job stress levels regarding job demand, organizational system, occupational climate at the work place were relatively high for the full time workers while the job stress levels regarding insufficient job control, job stability, interpersonal conflict, lack of reward were relatively high for the part time worker. The workers with longer total work years had relatively high job stress associated with interpersonal conflict, and organizational system while the workers with longer work years at the current job had relatively high job stress associated with occupational climate. Also, the workers with longer working hours a day had relatively high job stress associated with job demand, interpersonal conflict, organizational system, and occupational climate. According to the relationship identified in this study, symptoms at the neck, shoulder, hand, low back. leg were associated with the stress levels in terms of job flexibility, interpersonal conflict, job requirement, job stability. In conclusion, female bank workers are exposed to job stress due to their specific job characteristics and there has been certain relationships between their job stress and MSDs symptoms.

In the present study, fast and robust methods for the next generation sequencing (NGS) were developed for analysis of PRRSV full genome sequences, which is a positive sensed RNA virus with a high degree of genetic variability among isolates. Two strains of PRRSVs (VR2332 and VR2332-R) which have been maintained in our laboratory were used to validate our methods and to compare with the sequence registered in GenBank (GenBank accession no. EF536003). The results suggested that both of strains had 100% coverage with the reference; the VR2332 had the coverage depth from minimum 3 to maximum 23,012, for the VR2332-R from minimum 3 to maximum 41,348, and 22,712 as an average depth. Genomic data produced from the massive sequencing capacities of the NGS have enabled the study of PRRSV at an unprecedented rate and details. Unlike conventional sequence methods which require the knowledge of conserved regions, the NGS allows de novo assembly of the full viral genomes. Therefore, our results suggested that these methods using the NGS massively facilitate the generation of more full genome PRRSV sequences locally as well as nationally in regard of saving time and cost.

본고(本稿)서는, 최근 자유금융학파(自由金融學派)와 신화폐경제학과(新貨幣經濟學科)들의 등장으로 화폐(貨幣) 금융문제(金融問題)에서의 자유경쟁(自由競爭) 및 자유방임주의적(自由放任主義的) 사고가 새롭게 확산되고 있는 시점(時點)에서, 정부(政府) 및 중앙은행(中央銀行)의 화폐(貨幣) 금융개입(金融介入)의 이론적(理論的) 근거(根據)와 그에 관련된 논쟁(論爭)을 다음의 6가지 논거(論據)들을 중심으로 개관해 보았다 : (1) 자유금융하(自由金融下)의 銀行券(은행권) 초과발행(超過發行) 가능성(可能性), (2) 화폐사용에 있어서의 외부경제효과(外部經濟效果)와 화폐제도의 공공재적(公共財的) 성격(性格) (3) 화폐발행업무의 규모(規模)의 경제(經濟)와 자연독점적(自然獨占的) 성격(性格), (4) 실물부문(實物部門)의 불안정성(不安定性)과 거시안정화정책(巨視安定化政策)의 필요성, (5) 은행금융시장(銀行金融市場)의 불안정성(不安定性)과 은행파산(銀行破産)의 외부효과(外部效果), (6) 소액거래자(少額去來者) 및 예금자(預金者)의 보호(保護) 이러한 논거들에 의하면 외부화폐(外部貨幣)(outside money)의 공급은 전형적인 공공재이론(公共財理論)이나 기술적(技術的) 독점주장(獨占主張)이 적용되는 경우이기 때문에 외부화폐제도(外部貨幣制度)의 유지에 있어서 정부(政附)나 중앙은행(中央銀行) 독점(獨占) 및 개입(介入)이 불가피하고 또한 바람직하지만, 내부화폐(內部貨幣)(inside money)제도(制度)의 경우는 적절한 최소한의 안전장치만 강구된다면 최근의 자유금융학파(自由金融學派) 및 신화폐경제학과(新貨幣經濟學科)들의 주장과 같이 사적(私的) 자유경쟁(自由競爭)이 보다 활성화되도록 하는 것이 바람직할 것으로 판단된다 . 한편 외부화폐제도(外部貨幣制度)에의 개입(介入)에 따른 (정부(政府) 및) 중앙은행(中央銀行)의 거시통화정책기능(巨視通貨政策機能)은 물론, 보다 자유화(自由化)된 내부화폐제도하(內部貨幣制度下)에서도 중앙은행(中央銀行)의 최종대여자기능(最終貸與者機能)과 미시적(微視的) 감독기능(監督機能)은 동(同) 제도(制度)의 안전성(安全性)을 유지하기 위해 중요한 역할을 할 것으로 보인다.

Tapeworms of the genus Spirometra are pseudophyllidean cestodes endemic in Korea. At present, it is unclear which Spirometra species are responsible for causing human infections, and little information is available on the epidemiological profiles of Spirometra species infecting humans in Korea. Between 1979 and 2009, a total of 50 spargana from human patients and 2 adult specimens obtained from experimentally infected carnivorous animals were analyzed according to genetic and taxonomic criteria and classified as Spirometra erinaceieuropaei or Spirometra decipiens depending on the morphology. Morphologically, S. erinaceieuropaei and S. decipiens are different in that the spirally coiled uterus in S. erinaceieuropaei has 5-7 complete coils, while in S. decipiens it has only 4.5 coils. In addition, there is a 9.3% (146/1,566) sequence different between S. erinaceieuropaei and S. decipiens in the cox1 gene. Partial cox1 sequences (390 bp) from 35 Korean isolates showed 99.4% (388/390) similarity with the reference sequence of S. erinaceieuropaei from Korea (G1724; GenBank KJ599680) and an additional 15 Korean isolates revealed 99.2% (387/390) similarity with the reference sequences of S. decipiens from Korea (G1657; GenBank KJ599679). Based on morphologic and molecular databases, the estimated population ratio of S. erinaceieuropaei to S. decipiens was 35: 15. Our results indicate that both S. erinaceieuropaei and S. decipiens found in Korea infect humans, with S. erinaceieuropaei being 2 times more prevalent than S. decipiens. This study is the first to report human sparganosis caused by S. decipiens in humans in Korea.

A methodology is applied to identify tile learning trend related to the safety and availability of U.S. commercial nuclear power plants. The application is intended to aid in reducing likelihood of human errors. To assure that tile methodology ran be easily adapted to various types of classification schemes of operation data, a data bank classified by the Transient Analysis Classification and Evaluation(TRACE) scheme is selected for the methodology. The significance criteria for human-initiated events affecting tile systems and for events caused by human deficiencies were used. Clustering analysis was used to identify the learning trend in multi-dimensional histograms. A computer rode is developed based on tile K-Means algorithm and applied to find the learning period in which error rates are monotonously decreasing with plant age.
