Glyphosate is the active ingredient in widely used herbicides. It acts through inhibition of the shikimate metabolic pathway in plants. This pathway does not exist in mammals, however, so glyphosate is presumably less toxic to humans. Nevertheless, fatal cases of glyphosate poisoning in humans have still occurred. Cases of glyphosate poisoning reported in the previous literature were almost always caused by intentional ingestion. Therefore, intramuscular injection of glyphosate with suicidal intent has not been reported. We report a case of 43-year-old man with poisoning due to intramuscular injection of glyphosate herbicide. He was admitted to the emergency department with a chilling sensation, local hotness, swelling, and tenderness at the site of glyphosate injection. He was treated with intravenous antibiotics and analgesics for 10 days and was discharged without any other complication.

This research clarified a neuroscientific mechanism from somatics in dance contents developed using somatics methods through literature studies. To clarify these, first, I organized neuroscientific mechanism in somatics, second, researched neuroscientific mechanism in dance contents adopted from somatics practice. Somatics is limited to Feldenkrais Method. It is possible to explain neuroscientific mechanism through neuro-plasticity, proprioception and Sensory Integration. As a result Gaga and Tamalpa take the method Awareness thorugh Movement from Feldenrkrais. They integrate newly formed networks by informations from proprioceptive senses. This study is significant that suggest brain scientific practices in dances and somatics, explain mechanism between brain and body in dance practices and provide a base that explains mechanism of body movement in a view of brain science to choreographers and dancers to apply this mechanism in their study and training.

In essence, Musical theatre is a multimedia show, so when you listen to musical numbers, you will experience it through multiple senses. Therefore, in order to analyze musical numbers, emphasis should be placed on its interaction with various media such as lyrics, dance, and theatre, which have a direct association with the music. Through the Conceptual Blending Theory, which can comprehensively consider the combination of text and music, the combination of movement and music, and the combination of visual elements and music, this study analyzes the music of Musical . By exploring the result of interaction between lyrics and music, the interaction between choreography and music, and the interaction between stage and music, the artistry and intrinsic value of the work can be proved. In addition, we can discover the process and system of integrated interpretation through music analysis applying Conceptual Blending Theory. Therefore, Conceptual Blending Theory has sufficient utility as a methodology for music analysis of musical theatre.

Historically, the common folk have made use of various wild herbs for both food and medicinal purposes. However, the misuse of these wild herbs can lead to adverse consequences, including severe poisoning in some cases. In cases of poisoning from wild herbs, patients can exhibit a variety of symptoms depending on the herbs involved, which in addition to gastrointestinal symptoms may include hemodynamic alteration and abnormal neurologic signs. In the present case, two patients were admitted to the emergency room with symptoms of toxicity after consuming Rhododendron brachycarpum liquor. Rhododendron brachycarpum and other wild herbs contain the toxic material grayanotoxin. Because of its serious toxic symptoms, great caution must be exercised in using rhododendrons for food and medicinal purposes.

Among clincal isolates, most strains of Serratia marcescens were belonged to nonpigmented form, and several attempts were undertaken for the rapid and simple identification of these strains. Prodigiosin production of non-pigmented strains was uniformly negative in many kinds of solid media as well as in nutrient agar added with various amino acids and thiamine. On blood agar, colonies of S. marcescens turned gradually to grey or dark color by the lapse of incubation period and this characteristic seems to be able to utilize as an indicator for a primary isolation, and also generally paralleled with the results of dehydration of Tween 80 and lipase activity in soy bean oil medium although these reactions were by no means specific to S. marcescens. In order to rule out these non-specific reactions, other tests such as oxidase and sucrose fermentation are required for the final confirmation of this species.

국제핵융합실험로(ITER)에 장착되는 한국형 헬륨 냉각 고체형 증식(Helium Cooled Solid Breeder : HCSB) 시험 블랑켓(Test Blanket Module : TBM)은 ITER 참여국 중 유일하게 중성자 반사 재료를 채택한 것이 특징이다. 중성자 반사재료로는 지름 1 mm 내외의 흑연 페블을 사용 할 예정이다. 흑연은 중성자 반사특성은 우수하지만 기계적 특성이 비교적 좋지 않다는 단점이있다. 뿐만 아니라, 산화나 화재 등에 대해서도 취약하기 때문에 흑연이 노출된 상태로 사용하는 것은 위험부담이 클 수밖에 없다. 따라서 흑연을 코팅해서 사용하기 위한 연구개발이 진행 중이며, 코팅 후보물질로는 저방사화 및 고경도의 특성을 갖는 SiC가 유력시 되고 있다. 흑연위에 SiC를 코팅하는 방법은 여러 가지가 있으며, 그 중에서 비교적 간단한 RF Sputtering, PECVD를 이용해서 SiC를 코팅하고 그 특성을 평가했다. RF Sputtering에서 흑연의 온도를 상온으로 두었을 때는 SiC가 결정으로 성장되지 않는 것을 확인할 수 있었으며, $900^{\circ}C$ 이상의 온도에서 열처리과정을 거친 후 결정이 형성되는 것을 확인할 수 있었다. 그리고 열처리 온도가 $1200^{\circ}C$ 부근에서는 SiC nano-wire가 형성되는 것을 확인할 수 있었다. PECVD의 경우 전구체 물질로 사용된 $SiH_4$와 $CH_4$의 비율에 따라서 SiC의 형성비율이 다른 것을 알 수 있었으며, 결정 상태는 성장시 기판온도에 크게 의존하는 것을 확인할 수 있었다. 최근에는 보다 효율적으로 SiC를 코팅하기 위하여 흑연페블을 spouting시키면서 코팅할 수 있는 CVD 장치를 설계-제작했으며, 전구체 물질로는 $SiH_4$, $Si(CH_3)_4$, $CH_3$ $SiCl_3$ 등이 사용될 예정이다.

A cold roll-bonding process was applied to fabricate an AA1050/AA6061/AA1050 laminate complex sheet. Two AA1050 and one AA6061 sheets of 2 mm thickness, 40 mm width and 300 mm length were stacked up after surface treatment that included degreasing and wire brushing; material was then reduced to a thickness of 3 mm by one-pass cold rolling. The laminate sheet bonded by the rolling was further reduced to 1.2 mm in thickness by conventional rolling. The rolling was performed at ambient temperature without lubricant using a 2-high mill with a roll diameter of 210 mm. The rolling speed was 5.0 m/sec. The AA1050/AA6061/AA1050 laminate complex sheet fabricated by roll bonding was then hardened by natural aging T4) and artificial aging (T6) treatments. The microstructures of the as-roll bonded and the age hardened Al complex sheets were revealed by optical microscope observation; the mechanical properties were investigated by tensile testing and hardness testing. The strength of the as-roll bonded complex sheet was found to increase by 2.9 times compared to that value of the starting material. In addition, the hardness of the complex sheets increased with cold rolling for AA1050 and age-hardening treatment for AA6061, respectively. After heat treatment, both AA1050 and AA6061 showed typical recrystallization structures in which the grains were equiaxed; however, the grain size was smaller in AA6061 than in AA1050.

Character dance not only improves the expressive power of ballet majors, dancer and choreographers but also breathes life into the performance. Character dance, which has comprehensive educational implications, was difficult to conduct research due to lack of materials and incompleteness in the field of ballet education. Even popular concepts were not established. In order to establish the meaning of the character dance, this research examined the history of character dance from the Middle Ages to the present and the meaning and the category were also schematized. Also, I tried to find out the direction of development. Character dance through systematic categories and meaning establishment can provide extended educational forms to infants and children as well as dance majors and non-majors. This research of character dance is expected to provide basic materials not only for the ballet education but also for the various educations. Lastly, the author of this research is expecting that detailed researches will be conducted in the future.

Backgrounds and Objectives: In the length-dependent axonal polyneuropathy like diabetic polyneuropathy (DPN), the distal part of the longer axons are affected earlier. In cases of minimal distal axonal changes, nerve conduction studies (NCS) are frequently normal. If sural nerve is affected in the early stage of DPN, supportive parameters to detect the early axonal degeneration may be helpful. We investigated whether the sural/ulnar SNAP amplitude ratio (SUAR) may be a more sensitive indicator than sural amplitude alone in the diagnosis of early diabetic polyneuropathy. Methods: We analyzed medical records and electrophysiological studies of 141 patients with DM and 30 healthy subjects. The patients with early stage of DPN were defined as those having symptoms of neuropathy and normal NCS findings among the patients with DM. We compared SUAR between 57 patients with early stage of DPN and 71 agematched control subjects. Results: Fifty seven patients had an average SUAR of 0.8, compared to that of 1.1 in the 71 normal controls. The SUAR of less than 0.9 was supplementary predictor of axonal polyneuropathy, with the best balance of sensitivity and specificity (70%). The SUAR did not vary significantly with age, height or duration of DM. Conclusions: We conclude that the SUAR is a useful electrodiagnostic indicator to detect early stage of DPN.

Ultra Super Early Strength Cement is a material that satisfies these requirements. early hydration heat however, is significant over regular concrete, thus discretion is advised for thermal cracks in accordance with heat generation when constructing a large-scale structures. In addition, the negative point that it is difficult to achieve required strength in a short period of time following rubbing process while retaining workability, the cement is being used conditionally for engineering material and Ultra Super Early Strength Cement for maintenance material for construction doesn't exist. Magnesia Phosphate Cement, which is currently under studies in overseas uses no extra admixture and has strong points of Ultra Super Early Strength as well as favorable construction-ability and adhesive stability to the prototype concrete. These factors stem recognition that it could be used as maintenance material for construction of diverse applicability. In order to provide necessary data to increase practicality of the magnesia phosphate cement for Ultra Super Early Strength Mortar, the study carried out simulate experiment on member of framework to review field applicability.
