생수 내에는 많은 미네랄이 포함하고 있으며, 이 중 칼슘, 나트륨, 칼륨, 마그네슘, 불소는 생수통에 반드시 표기해야 할 무기물이다. 칼슘, 마그네슘, 불소와 같은 무기물은 치아형성에 관여하며, 적절하게 섭취시 치아우식증을 예방할 수 있다. 현행 먹는 샘물 수질기준에 따르면 무해무기물질인 칼슘과 마그네슘에 대한 기준치는 없으며, 유해무기물질인 불소와 같은 무기물은 2 mgF/L 이하로 규정하고 있다. 본 연구는 국내에서 판매되고 있는 생수 15종을 대상으로 칼슘, 마그네슘, 불소의 농도를 측정하였고, 생수 내 무기물 함량의 표기 여부 및 무기물 농도를 비교, 검토하여 다음과 같은 결론을 얻었다. 1. 15개의 생수 중 1개의 생수를 제외하고 모두 칼슘함량을 표기하였다. 평균 칼슘농도는 34.68±31.84 mg/L, 최대 12.891±1.85 mg/L, 최소 2.0±0.02 mg/L이었다. 2. 15개의 생수 중 2개의 생수를 제외하고 모두 마그네슘 함량을 표기하였다. 평균 마그네슘 농도는 9.22±11.06 mg/L, 최대 30.43±0.75 mg/L, 최소 0.0 mg/L이었다. 3. 15개의 생수 중 4개의 생수를 제외하고 모두 불소 함량을 표기하였다. 평균 불소 농도는 0.25±0.33 mg/L, 최대 1.13±0.04 mg/L, 최소 0.01±0.03 mg/L이었다. 모두 생수는 현행 먹는 샘물 기준치인 2 mgF/L 이하에는 만족시켰다. Drinking water has lots of minerals, especially calcium, sodium, kalium, magnesium, and fluoride must be labelled on the bottle about their contents. Minerals like calcium, magnesium, and fluoride have influence to the tooth development. Appropriately taking some minerals, dental caries can be prevented somewhat degree. There is no guide line about innoxious minerals like calcium and magnesium, however, noxious mineral like fluoride, should be contained less than 2 mgF/L according to the current drinking water standard. Hereupon, it is necessary to recognize the concentration of fluoride in drinking water, so I studied 15 samples of domestic drinking water on sale about the concentration of calcium and magnesium, fluoride. The results obtained were as follows ; 1. 14 drinking waters in 15 samples showed various Ca concentration. The average Ca concentration is 34.68±31.84 mg/L. the highest is 128.91±1.85 mg/L and the lowest is 2.0±0.02 mg/L. 2. 13 drinking waters in 15 samples indicate the Mg concentration. The average concentration is 9.22±11.06 mg/L. the highest is 30.43±0.75 mg/L and the lowest is 0.0 mg/L. 3. 11 drinking waters in 15 samples indicate the F concentration. The average concentration is 0.25±0.33 mg/L, the highest is 1.13±0.04 mg/L and the lowest is 0.01±0.03 mg/L. All samples are satisfied the current drinking water standard, 2 mg F/L.

Among the permanent teeth, the first permanent molars play the greatest role in occlusion and function. So, early diagnosis for congenital missing, abnormal eruption and abnormal formation is very important to the first permanent molars in the course of arch development. The aim of this study is to analyse the differences between right and left first permanent molar's formation and eruption and between upper and lower one. A total of 545 children were selected am ong children who had visited our clinic, investigate eruption and calcification stage of permanent first molar, based on Gleiser and Hunt criteria for this study. 1. Gingival emergence of mandibular first molar is faster than maxillary first molar by 0.75~0.8 years, gingival emergence of maxillary first molar in girls faster than boys by 0.45 years, and that of mandibular first molar in girls faster than boys by 0.5 years. 2. There is the significant difference between right and left first molar on the eruption score and the calcification stage ; 5 year old children show the significant difference on the eruption score. 7 year old children show the significant difference on both the eruption score and calcification stage. 3. It shows the most active eruption movement of crown on the maxilla while the root is rapidly widening its furcation and completing root formation to 2/3, on the other hand, the most active crown emerging on mandible is shown when the root formation completed to 1/4 to 1/2. 제1대구치는 치열의 교합 및 발육에 중요하게 관여하며 기능적, 형태적으로 건전한 교합의 발육 및 유지에 필수적인 치아이다. 치열의 발육과정에 있어서 제1대구치의 형성, 맹출 및 형태의 이상이나 선천결손의 발생여부를 조기에 진단하는 것은 매우 중요하다. 이 연구의 목적은 제1대구치의 맹출과 석회화 양상에 대해 조사하여 형성과 맹출의 상, 하악과 좌, 우 차이에 대해 평가하는 것이다. 2007년 7월부터 2008년 6월까지 전북대학교 치과병원 소아치과에 내원하여 파노라마 방사선사진을 촬영한 545명의 어린이를 대상으로, 제1대구치의 맹출 위치와, Gleiser and Hunt의 석회화단계의 분류를 이용하여 제1대구치의 석회화에 대해 연구한 결과 다음과 같은 결론을 얻었다. 1. 제1대구치의 구강내 출은은 하악 제1대구치의 구강내 출은이 상악 제1대구치의 출은보다 0.75~0.8년 빠르게 일어났으며, 여성은 남성에 비해 상악은 약 0.45년, 하악은 약 0.5년 먼저 출은했다. 2. 제1대구치의 석회화단계와 맹출 정도의 좌, 우 차이는, 5세에서 상악 좌, 우측 맹출 정도와, 7세에서 상악 좌, 우측 맹출정도, 하악 좌, 우측 석회화단계가 유의한 차이를 보였다. 3. 상악은 치근 분지부의 급속한 확대단계와 치근 2/3완성단계 사이에서, 하악은 치근 1/4완성단계와 치근 1/2완성단계 사이에 가장 많은 맹출 이동량을 보였다.

Background: Onychomycosis, especially toenail onychomycosis has become one of the common fungal infection and has historically been regarded as a cosmetic rather than medical problem by many patients, even by physicians. Recently, however, there are several reports that is a refractory disease which may cause a deleterious effect on patiets quality of life (QOL). Objective: The purpose of this study was to investigate the impact of toenail onychomycosis on QOL in Korea and to assess the chandes of QOL after treatment. Methods: Total 1004 patients with toenail onychomycosis which was confirmed by clinical findings and KOH preparation were were enrolled at 47 dermatologic centers in Korea, and interviewed with standardized QOL questionnaire before and after sytemic antifungal treatment. Responses to the questionnaire were scored by 5-point scale (1∼4) and averaged, and were analyzed for 5 dimensions of emotional impact, social impact, symptorn and functional impact, patients views concerning treatment, and relationship with doctor. Results: 1. Before and after treatment, the most serious impact was emotional dimension showing 1.90 and 1.30 in average score (AS), and social (AS: 1.14 and 0.83) and symptom and functional impact (AS: 1.05 and 0.92) was also affected. 2. In female rather than male, statistically more significant impact on patients QOL was observed in all dimensions. 3. After treatment, 3 of 5 dimensions were improved significantly - emotional dimension (AS : from 1.90 to 1.30), social dimension (AS: from 1.14 to 0.83), patients view concerning treatment (AS: from 1.34 to 1.02). 4. The drgree of patients satisfaction at the therapeutic effect was very high- 62.4% (immediately after treatment) and 65.8% (9 months affer initiation of treatment) of patients answered excellent or good. Conclusion: This study confirms that toenail onychomycosis has significant impact on the overall QOL of patients. Also the effect of antifungal therapy on patients QOL were watisfactory. Therefore, both doctor and patient should pay more attention to the treatment of onychomycosis. [Kor J Med Mycol 3(1): 115∼124]

Kim, Nam Hoon,Kwon, Tae Yeon,Yu, Sungwook,Kim, Nan Hee,Choi, Kyung Mook,Baik, Sei Hyun,Park, Yousung,Kim, Sin Gon American Heart Association, Inc. 2017 Stroke Vol.48 No.4

<P>Conclusions Higher IFG degree (fasting glucose, 110-125 mg/dL) was associated with increased all-cause and vascular disease mortality. The increased vascular disease mortality in IFG stage 2 was attributable to ischemic stroke, but not ischemic heart disease or hemorrhagic stroke in Korean adults.</P>

<▼1><P>Supplemental Digital Content is available in the text</P></▼1><▼2><P><B>Abstract</B></P><P>The fat mass and obesity-associated (FTO) rs9939609 polymorphism have been associated with the increased metabolic risk and mortality, irrespective of obesity. The mechanism underlying this association is not known. We aimed to evaluate whether the FTO rs9939609 risk variant is independently associated with metabolic risk factors and/or leukocyte telomere length (LTL). We further aimed to investigate whether this relationship is modified by obesity status.</P><P>A total of 2133 participants were recruited from the Korean Genome and Epidemiology Study. LTL was measured using the real-time quantitative polymerase chain reaction methodology. The <I>FTO</I> rs9939609 polymorphism was genotyped using DNA samples collected at baseline.</P><P>The proportions of the TT, TA, and AA genotypes were 76.7%, 21.5%, and 1.8%, respectively, and obese subjects comprised 44.5% of the total subjects. Among the 1184 nonobese subjects, body mass index, waist circumference, and visceral fat area were higher in subjects with the <I>FTO</I> risk allele than in noncarriers. In contrast, only high-sensitive C-reactive protein level was associated with the <I>FTO</I> risk allele in the obese subjects. LTL was significantly shorter in carriers of the <I>FTO</I> risk allele compared with noncarriers after controlling for several confounding factors (<I>P</I> < .01). Of particular note, this significant association between the <I>FTO</I> risk allele and LTL appeared only in nonobese subjects (<I>P</I> = .03). Multivariate linear regression analyses identified older age, low high-density lipoprotein cholesterol level, and the presence of the <I>FTO</I> risk allele as independent risk factors affecting LTL. This finding was evident only in nonobese subjects.</P><P>The <I>FTO</I> rs9939609 polymorphism is an independent risk factor for obesity and also for biological aging in the nonobese population.</P></▼2>

Long-Range Lattice Engineering of MoTe₂ by a 2D Electride

Kim, Sera,Song, Seunghyun,Park, Jongho,Yu, Ho Sung,Cho, Suyeon,Kim, Dohyun,Baik, Jaeyoon,Choe, Duk-Hyun,Chang, K. J.,Lee, Young Hee,Kim, Sung Wng,Yang, Heejun American Chemical Society 2017 NANO LETTERS Vol.17 No.6

<P>Doping two-dimensional (2D) semiconductors beyond their degenerate levels provides the opportunity to investigate extreme carrier density-driven superconductivity and phase transition in 2D systems. Chemical functionalization and the ionic gating have achieved the high doping density, but their effective ranges have been limited to similar to 1 nm, which restricts the use of highly doped 2D semiconductors. Here, we report on electron diffusion from the 2D electride [Ca2N](+)e to MoTe2 over a distance of 100 nm from the contact interface, generating an electron doping density higher than 1.6 x 10(14) cm(2) and a lattice symmetry change of MoTe2 as a consequence of the extreme doping. The long-range lattice symmetry change, suggesting a length scale surpassing the depletion width of conventional metalsemiconductor junctions, was a consequence of the low work function (2.6 eV) with highly mobile anionic electron layers of [Ca2N](+)e . The combination of 2D electrides and layered materials yields a novel material design in terms of doping and lattice engineering.</P>
