Objective: Habitual snoring is a common problem in children. We evaluated the association between a high risk for sleep-disordered breathing and attention deficit/hyperactivity symptoms. Methods: Parents of 13,560 children aged 6 to 12 years responded to questionnaires including items on habitual snoring and the Korean attention deficit/hyperactivity disorder rating scale. The snoring score comprised the number of “yes” responses to habitual-snoring items, and a high risk for sleep-disordered breathing was defined as a snoring score ≥ 2. Results: The odds ratio (OR) of a high risk for sleep-disordered breathing was significantly higher in boys (OR = 1.47; p < 0.001), overweight children (OR = 2.20; p < 0.001), and children with current secondhand-smoking exposure (OR = 1.38; p < 0.001). The Korean attention deficit/hyperactivity disorder rating scale score increased significantly with the snoring score (0 vs. 1, B = 1.56, p < 0.001; 0 vs. 2, B = 2.44, p < 0.001; 0 vs. 3, B = 2.48, p < 0.001; 0 vs. 4, B = 3.95; p < 0.001). Conclusion: Our study confirms several risk factors of sleep-disordered breathing, namely male sex, overweight, and exposure to tobacco smoking, and found a positive association between habitual snoring and attention deficit/hyperactivity symptoms.

귀리(Avena Sativa L., Oat)에서 이삭모양과 탈부특성이 다른 겉귀리와 쌀귀리를 품질특성으로 구분하고자 12 품종 귀리종실의 이화학적 특성 및 식이섬유를 분석하였고, 61개의 SSR 분자마커를 이용하여 근연관계 및 조양 판별 마커조합을 설정하였으며 결과를 요약하면 다음과 같다. 1. 공시한 12개의 귀리 품종을 생육조사 한 결과 쌀귀리는 이삭의 한 소수에서 영화수가 4~5개 생기는데 비해 겉귀리는 2~3개 생겼으며, 탈곡 후 종실의 껍질 유무 또한 쌀귀리는 없었고 겉귀리는 껍질이 남아있는 형태로 기존에 알려진 것과 같은 결과를 보였다. 2. 단백질은 쌀귀리가 13.45 ~ 16.56%, 겉귀리는 12.95 ~ 15.31%의 함량 분포를 나타내었으며, 지방은 쌀귀리가 7.26 ~ 10.34%, 겉귀리는 7.53 ~ 10.82%의 함량 분포를 나타내었으며, 베타글루칸은 쌀귀리가 4.19 ~ 5.05%, 겉귀리는 3.49 ~ 5.60%의 함량 분포를 나타내어 귀리 품종 간에는 품질특성이 차이가 나타났으나 쌀귀리와 겉귀리를 구분 할 수 있을 정도는 아니었다. 3. 지방산 조성 비율은 쌀귀리가 겉귀리에 비해 올레인산(C18:1, Oleic acid, 40.2 ~ 50.9%)과 스테아르산(C18:0, Stearic acid, 1.2 ~ 2.5%)이 높은 비율을 나타냈으며, 겉귀리는 쌀귀리에 비해 리놀레산(C18:2, Linoleic acid, 30.6 ~ 41.2%)과 리놀렌산(C18:3, Linolenic acid, 0.7 ~ 1.3%)이 더 높은 비율을 보였다. 4. 귀리의 근연관계는 계수(Coefficient) 1.22에서 그룹 하여 정리한 결과 겉귀리 6품종과 쌀귀리 1품종으로 그룹 되었고 유전적 거리(Genetic Distance)는 '동한'과 '태한'이 가장 가깝게 나타났으며 다음은 '풍한', '삼한', '옥한', '조풍', '중모2005' 순으로 나타났다. 계수(Coefficient) 1.22에서 그룹 되지 않은 귀리는 겉귀리 1품종과 쌀귀리 4품종으로 '수양', '다한', '대양', '선양', '조양' 순으로 그룹에서 먼 것으로 나타나 대체적으로 겉귀리와 쌀귀리가 서로 멀게 나타났다. 5. 12개의 귀리품종에 61개의 SSR maker를 이용하여 분석한 결과 '조양'은 AM28, 29, 32, 34, 36의 5개 SSR마커에서 다른 품종과 다른 밴드 패턴을 나타내어 품종 구분이 가능하였다. The consumption of oats (Avena sativa L.) with high nutritional utility is accelerating due to the increased consumers' demand for functional foods. In Korea, naked oats are used as food, while covered oats are used for animal feed. However, it is difficult to distinguish naked oats from covered oats when the husk is removed from the grains by a special process. The present study was carried out to investigate experimental methods that would be beneficial in the segregation of different types of oats after husk removal. Grain quality-related biochemical compounds were analyzed in a bid to differentiate the oat dehulling characteristics. In addition, 61 SSR markers were examined for genetic relationship and variety identification of oats using five naked and seven covered oat varieties. Results showed that, the contents of protein, lipid, and ${\beta}-glucan$ were not significantly different among the oat varieties and this could not be used as an index for distinguishing oats husk character. However, in the fatty acid composition ratio,, naked oats had a higher ratio of stearic acid (C18:0) and oleic acid (C18:1) than covered oats, and covered oats had a higher ratio of linoleic acid (C18:2) and linoleic acid (C18:3) than naked oats. The assessment of SSR marker genotype revealed that 33 polymorphic bands among 12 oat varieties and 1 variety could be distinguished through the combination of polymorphic markers thus indicating the usability of these markers for variety identification in oats.

증강현실 기술은 실제공간에 가상정보를 실시간으로 증강하여 사용자가 증강된 가상정보와 상호작용함으로써 작업의 효율성을 향상시키는 기술이다. 최근 증강현실 기술이 발달함에 따라 군사훈련에 적용하기 위한 연구도 활발하게 진행되고 있다. 훈련 중 대민피해, 소음 등으로 인한 민원이나 안전사고 등으로 인해 실전적인 훈련이 제한되어 증강현실 기술 기반의 훈련체계 도입이 불가피하나 현재 개발되고 있는 증강현실 기술을 이용한 군사훈련 시스템들은 대부분 실내 훈련 시스템으로 별도의 설치공간이 필요하고 고비용으로 인해 특수훈련 위주로 개발이 진행되고 있어 우리 군의 소대 이하 규모의 소부대 훈련 시스템으로 활용하기에는 제한사항이 존재한다. 본 논문에서는 증강현실 기술을 소대 이하의 소부대가 주둔지의 야외 훈련장에서 활용할 수 있는 방안을 제시하고 이를 통해 얻을 수 있는 효과와 법제도적 측면에서의 고려사항을 제시한다. According to the dictionary definition Augmented Reality Technology is "an enhanced version of reality where live direct or indirect views of physical real-world environments are augmented with superimposed computer-generated images over a user's view of the real-world, thus enhancing one's current perception of reality". Since civilian property damages, noise and accidents during the field exercise by military or drills so that AR technology are indispensible with small units drills in Army. However because AR technology which Army has adopted are usually use for special units or need separate spaces which costs lots of budgets, those are not fit for small unit drills or tactics in regular Army. In this regards this paper suggests the AR technology which can apply small unit drill field and the efficiency and legal concerns thereof as well.

김경민,이성갑,권민수,김영곤,Kim, Kyeong-Min,Lee, Sung-Gap,Kwon, Min-Su,Kim, Young-Gon 한국전기전자재료학회 2017 전기전자재료학회논문지 Vol.30 No.6

In this paper, we investigated the effect of Co content on the microstructural and electrical properties of $Ni_{0.79}Mn_{2.21-x}Co_xO_4$ (x=0 to 0.25) specimens. Solid-state reaction was used to prepare the bulk specimens. XRD (X-ray diffraction) patterns showed that all compositions had a cubic spinel phase. As a result of the microstructural properties, FE-SEM(field-emission scanning electron microscopy) analysis showed a dense structure, and the mean grain size increased from $5.24{\mu}m$ to $7.33{\mu}m$ with an increase of Co content from x=0 to 0.25. All specimens exhibited the typical NTC thermistor characteristics as the electrical resistance exponentially decreased with increasing temperature. The resistivity and the B-value of $Ni_{0.79}Mn_{1.96}Co_{0.25}O_4$ were $2959{\Omega}{\cdot}cm$ and 3719, respectively.

Purpose: DiGeorge syndrome (chromosome 22q11.2 deletion syndrome) is a syndrome of multiple congenital anomalies characterized by hypoplasia or aplasia of the thymus and parathyroid, cardiovascular malformation, immune deficiency, cleft palate, characteristic facial features, and hypocalcemia. Ocular findings of DiGeorge syndrome are posterior embryotoxon, retinal vascular tortuosity, strabismus, ptosis, amblyopia and tilted optic disc. The authors present a case of DiGeorge syndrome with ocular manifestation not reported previously in Korea. Case summary: A six-year old female diagnosed with DiGeorge syndrome was referred to the authors’ department within the hospital. The chief complaint was blurring vision in both eyes. Best corrected visual acuity of the right eye was 0.5 and of the left eye was 0.63. Cycloplegic refraction revealed high hyperopia and astigmatism in both eyes (OD: +7.25 Dsph; -2.5 Dcyl axis 180°, OS: +6.25 Dsph; -3.75 Dcyl axis 180°). In addition, hypertelorism, ptosis and tortuous retinal vessels during fundus examination were noted. Conclusions: Upon the initial diagnosis of DiGeorge syndrome in children, a comprehensive ocular examination is necessary because other ocular conditions may exist which can affect the visual development of the patient.
