동남아시아를 여행하고 귀국한 후부터 시작된 약 1개월 동안의 복통, 설사 및 체중 감소를 주소로 내원한 서울이 거주지인 32세의 남자 환자가 구충증으로 진단되었다. 혈액 검사상 백혈구 수(16,750개111) 및 호산구의 백분율(33.7%)이 모두 상승되어 있었으나 빈혈 소견은 없었다. 대변 검사상 전형적인 구충의 충란이 대량 발견되었으며, S상결장경검사시 직장에서 적출된 충체 3마리를 관찰한 결과, 기생 부위가 전형적이지는 않았으나, 구강 및 생식기 등의 형태학적인 특징을 고려하여 듀비니구충(Ancylestoma duodenale)의 성충(♂: 1, ♀: 2마리)으로 동정 할 수 있었다. 구충제 (aetendazole)를 투여한 후 상기한 모든 증상이 급속히 호전되었다. 해외 여행시 감염되어 국내에 수입된 기생충 감염의 한 중례로 생각되며, 인체의 대장에 이소기생 (이소기생)한 구충 감염을 직접 확인한 드문 경우로 생각된다.

The purpose of this study is to search the level of localization strategy of imported brands in Korean Market, to investigate relationship between the brand characteristics and localization strategy, and to study the case about localization strategy of the brand selected according to the type of brand. The survey research was employed and for the data analysis, descriptive statistics, one-way ANOVA, and multiple-regression were used. For the case study, interview with the person who works in the each kind of company was used. The results of this study were as follows: Firstly, the level of localization strategy is found in order price, place, promotion and product. Secondly among the brand characteristics, type of brand, proportion of garments, price zone, launching time, number of shop are related with localization strategy, but turnover and number of the staff are not. Thirdly, license brand has the characteristics like as national brands and the differences between the branch and the agent is confidence and communication that are the basic elements of localization. This study can help national brands to refer the localization strategy and provide the understanding of localization strategy of imported brands in Korean fashion market.

Human babesiosis is a tick-borne disease induced by the genus Babesia and has been significantly reported in the Republic of Korea. This report shows the cases of 2 patients with human babesiosis who traveled to the USA in 2019. The 2 patients experienced fever and had travel histories to babesiosis-endemic regions. The diagnoses of both cases were verified by the identification of Babesia-infected red blood cells on blood smears. One patient was found to be infected with Babesia microti using polymerase chain reaction (PCR) for 18S rRNA, which discovered the phylogenetic link to the B. microti strain endemic in the USA. The 2 patients recovered from fever with subsequent hemoparasite clearance. Babesiosis could be diagnosed in anyone with histories of travel to babesiosis-endemic countries and tick bites. Furthermore, Babesia-specific PCR is required for determining geno-and phenotypic characteristics.

Echinococcus granulosus, an intestinal tapeworm of dogs and other canids, infects humans in its larval stage and causes human echinococcosis or hydatid disease. In the Republic of Korea, 31 parasite-proven human echinococcosis cases have been reported, most of which were imported from the Middle East. We recently examined a 61-year-old Korean man who had a large cystic mass in his liver. ELISA was negative for tissue parasitic infections, including echinococcosis, cysticercosis, paragonimiasis, and sparganosis. The patient underwent surgery to remove the cyst, and the resected cyst was processed histopathologically for microscopic examinations. In sectioned cyst tissue, necrotizing protoscolices with disintegrated hooklets of E. granulosus were found. In some areas, only freed, fragmented hooklets were detected. The patient had traveled to western and central Europe in 1996, and had no other history of overseas travel. We report our patient as a hepatic echinococcosis case which was probably imported from Europe.

본 연구에서는 국내에서 주로 소비되는 국내산 및 수입산 참돔의 일반성분과 중금속 함량을 비교 분석하였고 생리활성을 비교하기 위하여 참돔을 용매의 극성에 따라 추출하여 항산화 및 세포독성 효과에 대해 연구하였다. 수입산과 비교했을 때 국내산 참돔은 높은 함량의 수분과 낮은 함량의 조지방, 조단백질 및 회분을 나타내었다. 국내산 및 수입산 참돔의 중금속 함량을 비교한 결과 원산지에 따른 유의적 차이를 보였으며 국내산 참돔의 수은 함량은 0.08 mg/kg으로 수입산 참돔보다 높은 함량을 나타내었으나 납의 경우 원산지에 따른 유의적 차이는 보이지 않았다. 국내산 및 수입산 참돔의 A+M 및 MeOH 추출물을 인체 섬유육종세포(HT-1080)에 처리하였을 때, 세포 내 활성산소종 생성 저해효과를 살펴 본 실험 결과, 국내산 및 수입산 참돔 추출물들에 의한 활성산소종 생성 억제효과를 비교해 보면 수입산 참돔 추출물에 의한 저해효과가 높았으며 두 추출물들 중 MeOH 추출물에 의한 저해효과가 높았음을 알 수 있었다. 인체 암세포들(AGS 및 HT-29)들에 대한 세포독성 활성 결과에서 AGS 암세포의 경우 국내산 참돔 A+M 및 MeOH 추출물들에 의한 세포독성 효과가 수입산 참돔A+M 추출물들보다 높았다. HT-29 암세포에 대해서는 국내산 참돔A+M 추출물에 의한 세포독성 효과가 수입산 참돔 A+M 추출물에 의한 것보다 높았고 MeOH 추출물에 의한 세포독성 효과는 유사했다. 따라서 본 연구 결과를 기초자료로 하여 향후 참돔의 다양한 생리활성 규명이 필요하다고 사료된다.

Human diphyllobothriasis is a parasitic disease caused by ingestion of larvae (plerocercoids) in raw or undercooked fish and commonly found in temperate areas. Rare cases were reported in tropical or subtropical areas especially in children. The first documented case of pediatric diphyllobothriasis in Taiwan had been reported 11 years ago. Here, we report another 8-year-old girl case who presented with a live noodle-like worm hanging down from her anus, with no other detectable symptoms. We pulled the worm out and found the strobila being 260 cm in length. Examination of gravid proglottids showed that they were wider than their lengths, containing an ovoid cirrus sac in the anterior side and the rosette-shaped uterus. Eggs extracted from the uterus were ovoid and operculated. Diphyllobothrium latum was confirmed by molecular analysis of the mitochondrial DNA cytochrome c oxidase subunit 1 (cox1) gene. The girl was treated with a single oral dose of praziquantel, and no eggs or proglottids were observed from her stool in the subsequent 3 months. The reemergence of human diphyllobothriasis in non-endemic countries is probably due to prevalent habit of eating imported raw fish from endemic areas. This pediatric case raised our concern that human diphyllobothriasis is likely underestimated because of unremarkable symptoms.

두 형태 진균은 자연환경이나 배지에 접종하여 실온에($25{\sim}30^{\circ}C$)에서 배양하면 균사체를 형성하는 특성을 가지고 있으며, 체온이나 높은 온도($35{\sim}37^{\circ}C$)에서 배양을 하면 효모형태를 나타나는 특성이 있다. 풍토병 지역에서만 발생하는 이들은 전신감염을 일으키며, 조직이나 기관에 침입하여 심부 진균 증을 일으키는 원인 진균이다. 사람에 감염되는 두 형태 진균은 지금까지 Blastomyces dermatitidis, Coccidioides immitis, Sporothrix schenkii, Talaromyces (Penicillium) marneffei, Histoplasma capsulatum, 그리고, Paracoccidioides brasiliensis 여섯 균종으로 알려져 있다. 지금까지 해외에서 유입되어 국내에 보고된 두 형태 진균은 Coccidioides immitis가 18예, Histoplasma capsulatum이 5예, Blastomyces dermatitidis가 3예, 그리고 Talaromyces (Penicillium) marneffei 가 4예로 모두 30예의 두 형태 진균이 보고되었다. 유행지역의 방문경험이 없음에도 국내에 발생된 경우는 C. immitis가 3예, H. capsulatum이 2예, B. dermatitidis가 1예, 그리고 Talaromyces (Penicillium) marneffei 가 1예로 있다. Sporothrix schenkii 를 제외한 모든 두 형태 진균이 국내에서는 발생하지 않고 외국의 특정 국가와 한정된 지역에서만 발생하는 풍토병 원인의 토착 진균이지만, 유행 지역의 여행 경험이나 호발 지역의 이민 거주자들의 귀국과 국내로 유입되는 외국인의 증가 추세를 고려하면 해외유입 감염증의 발생은 점점 증가할 것으로 사료된다.

Finding solutions for the disabled is a major challenge for our society. In the case of a disability due to a malfunction of the nervous system, the origin may be accidental, genetic, or induced by environmental factors. This type of loss can cause loss or movement disorders (paraplegia, hemiplegia, quadriplegia, epilepsy, Parkinson's disease, multiple sclerosis, etc.) or malfunction of certain sensory functions (blindness, deafness, chronic pain, etc.). Many alternatives, more technology, have been imported to create interfaces between the human body and an artificial prosthesis in order to restore some functions of the human body. A wireless system, battery neurons probe was developed for one hand reading neural signals in the brain, and on the other hand also able to excite the neuron in the brain using a surface acoustic wave one ports (SAW) delay line reflection.

Human Gnathostoma hispidum infection is extremely rare in the world literature and has never been reported in the Republic of Korea. A 74-year-old Korean man who returned from China complained of an erythematous papule on his back and admitted to our hospital. Surgical extraction of the lesion and histopathological examination revealed sections of a nematode larva in the deep dermis. The sectioned larva had 1 nucleus in each intestinal cell and was identified as G. hispidum. The patient recalled having eaten freshwater fish when he lived in China. We designated our patient as an imported G. hispidum case from China.

This study aims to examine and measure the impact of capital structure on the profitability of companies in emerging markets. The research sample includes eighteen rubber companies listed on the Vietnam stock exchange from 2015-2019. After collecting the research data, it was imported into excel to calculate the criteria for the research model. By using Stata 16 software, the study selected a data processing model and evaluated the relevance of the regression analysis model. The research results show that the profitability of listed rubber companies in Vietnam (measured by return on equity (ROE) has a positive relationship with the debt-to-asset ratio but has a negative relationship with the long-term debt-to-asset ratio. The results also show a positive impact of firm size and revenue growth on profitability while liquidity and the ratio of tangible fixed assets to total assets do not affect significantly. These results are consistent with most of the previously published studies. However, in contrast to many previous studies, our study shows that the long-term debt-to-assets ratio has a negative effect on profitability while the debt-to-asset ratio has a positive effect. This is entirely consistent with the characteristics of long-term debt use in emerging markets.
