Scombroid fish poisoning (SFP) is a form of histamine food poisoning caused by the ingestion of improperly stored fish. The term "scombroid" derives from the family name of the fish family first implicated, such as tuna and mackerel. On the other hand, non-scombroid fish species, such as sardine and herring, can also cause histamine poisoning. The histamine is converted from histidine by a bacterial enzyme in the causative fish. Because the symptoms of SFP can easily be confused with food allergies, it is believed to have been significantly under-reported. In 2016, an outbreak of SFP occurred among primary school students who had eaten yellowtail steak in Korea. The most common findings consisted of a rapid onset of flushing of the face and trunk, erythematous and urticarial rash, diarrhea, and headache occurring soon after consuming the spoiled fish. Usually, the course is self-limiting and antihistamines can be used successfully to relieve symptoms, but several life-threatening SFP cases have been reported. Clinical toxicologists should be familiar with SFP and have competency to make a differential diagnosis between fish allergy and histamine poisoning. SFP is a histamine-induced reaction caused by the ingestion of histamine-contaminated fish, whereas a fish allergy is an IgE-mediated reaction. This review discusses the epidemiology, pathophysiology, diagnosis, treatment, and preventive measures of SFP.

Mucormycosis is the common name given to several different diseases caused by fungi of the order Mucorales. The mucoraceae are ubiquitous fungi and are common inhabitants of decaying matter. In contrast to the widespread distribution of these fungi, disease in humans is limited, in most cases, to people with severe immunocompromised, diabetes mellitus, or trauma. 1be fungus gains entry to the body through the respiratory tract. The spores are presumably deposited in the nasal turbinates and may be inhaled into the pulmonary alveoli. The manifestations of mucormycosis are rhinocerebral, pulmonary, cutaneous, gastrointestinal, central nervous system, and miscellaneous. Sporadic reports can be found of mucormycosis involving other areas : heart, bones, kidney, bladder, mediastinum, and trachea. However, isolated tracheal mucormycosis is very rare. Therefore, we report a 57-year old, noninsulin dependent diabetic woman who presented with acute, severe degree of upper airway obstruction due to isolated mucormycosis of the trachea.

Red algal parasites are common within red algae and are mostly closely related to their hosts, but have a reduced habit. In the past, red algal parasites, due to their reduced morphology, have been given distinct generic names, even though they are often phylogenetically nested in their host's genus. This is a problem nomenclaturally for maintenance of a taxonomy based on monophyly. This study investigates the morphology, genetic variation and distribution of an undescribed red algal parasite growing on its host Rhodophyllis membranacea, widely distributed throughout New Zealand. Microscopy, molecular markers (plastid, mitochondrial, nuclear), and herbarium investigation were used to investigate this species. The parasite is widely distributed throughout New Zealand. All molecular markers clearly show that the parasite is almost identical to the host, even though morphologically quite distinct from members of the host genus. We believe that to maintain monophyly of Rhodophyllis the parasite should be described as a new species of Rhodophyllis, Rhodophyllis parasitica sp. nov. We also recommend that in order to maintain generic monophyly most red algal parasite genera should also be transferred to their host genus.

1998년 나주와 밀양에서 재배중인 복숭아와 자두에서 세균성 구멍병이 발생하였다. 복숭아와 자두의 병반으루부터 분리한 균주의 세균학적 특성을 조사한 결과, 병원세균 중 2균주는 Xanthomonas campestris pv. pruni로, 3균주는 Erwinia nigrifluens로 동정되었다. E. nigrifluens는 국내에서는 복숭아와 자두의 세균성 구멍병으루 처음 분리되었다. 이 균주는 X. campestris pv. pruni에 의한 병징과 구분하기가 곤란하고, 2종류의 병워세균이 동시에 침입하여 발병하는 것으루 관찰되었다. 이와 같은 이유로, E. nigrifluens와 X. compestris pv. pruni에 의한 복숭아와 자두의 세균병을 각각 \"복숭아, 자두의 세균성구멍병\"로 명명할 것을 제안한다.할 것을 제안한다.

유니코드가 나오기 전까지는 프로그램용 이두문자의 사용이 불가피한 면이 있었다. 그러나 유니코드가 국제표준으로 명실공이 자리 잡은 지금에도 한글 식별자의 사용을 피해야 한다고 주장하는 것은 세종 이후 지속적으로 한글 사용을 천시하고 반대한 것과 비슷한 측면이 있다. 본 연구에서는 컴퓨터학과 학생들을 대상으로 한 설문조사를 통해 영어 식별자 사용을 선호하는 이유와 한글 식별자를 사용한다고 할 때 영어 대문자의 기능을 대체할 표기법에 대한 선호도를 조사하였다. 그리고 영어 식별자 사용의 대세론이 허망함에 대해 논의하고, 한글 식별자 사용을 위한 두 가지 명명법을 제안하였다. 소프트웨어 생산성 향상을 위해, 프로그래머의 작업 만족도 향상을 위해, 유지보수의 용이성을 위해 한글 식별자 사용이 조속히 보편화될 필요가 있다.

The purpose of this study was to develop a large representative data base for socks marketing strategy. The study was to determine socks brand awareness in ralation to segmented distribution regions and such demographic variables as sex and age. The authors also analyzed preferred design. A total of 650 questionnaires were distributed and 611 reliable ones were used for statistical analysis. A SAS statistical package including frequency tables and chi square test was used. The results are as follows: Brand awareness involves "brand recall" based on asking a person to name the brand he or she recalls first, and also "brand recognition" based on asking subjects to identify brand names from 30 given brands. 'SOCKSTOP' was found to be a dominant brand as a result of the brand recall test, and 'BYC' was found to be a dominant brand as a result of the brand recognition test. Brand recognition was significantly different in the segmented distribution regions, three age groups and different sex groups. People considered design first in purchasing sports/casual socks, while they considered color first in purchasing dress socks. The most favored type of sock style was the common crew sock type. The results of a chi square test showed that preferred type of sock design was related with the sex and age variables.

Elliptic curves are a common theme among various fields of mathematics, such as number theory, algebraic geometry, complex analysis, cryptography, and mathematical physics. In the history of elliptic curves, we can find number theoretic problems on the one hand, and complex function theoretic ones on the other. The elliptic curve theory is a synthesis of those two indeed. As an overview of the history of elliptic curves, we survey the Diophantine equations of 3rd degree and the congruent number problem as some of number theoretic trails of elliptic curves. We discuss elliptic integrals and elliptic functions, from which we get a glimpse of idea where the name 'elliptic curve' came from. We explain how the solution of Diophantine equations of 3rd degree and elliptic functions are related. Finally we outline the BSD conjecture, one of the 7 millennium problems proposed by the Clay Math Institute, as an important problem concerning elliptic curves.

The purpose of this study was to analyze the signification system between logo and brand image systematically in imported fashion luxury brands through semiotic approach. For this purpose, 29 luxury brands were selected from 3 department stores. According to the visual characters of logo, the types of logo used in the imported fashion luxury brands were classified into three types and the results of this study were following : First, the luxury brands used the brand logo in common that represent the name of founder or fashion designer to deliver the character of company's own brand and to emphasize the spirit of a craftsman. Second, the luxury brands also used the brand logo that design the brand initial in symmetry of the right and left or top and bottom to emphasize a unique spirit of the brand. Third, the luxury brands used the brand logo that represent or symbolize a specific animal or object to express the special quality of the brand in descriptive type. Forth, the luxury brands used the most frequently black color in brand logo that symbolize a perfection, immortality and solemnity, etc.
