김성진,송제선,김익환,김성오,최형준,Kim, Seong Jin,Song, Je Seon,Kim, Ik-Hwan,Kim, Seong-Oh,Choi, Hyung-Jun 대한소아치과학회 2021 大韓小兒齒科學會誌 Vol.48 No.3

이 연구의 목적은 한국 아동의 골 성숙 단계와 여러 치아들의 석회화 단계 간의 상관관계를 알아보고자 하는 것이다. 만 6 - 14세의 남아 359명, 여아 384명의 수완부 방사선사진, 측방두부규격 방사선사진, 파노라마 방사선사진을 분석하여 평가하였다. 하악 좌측의 7개 영구치의 치아 석회화 단계는 Demirjian이 제시한 방법에 의해 평가되었다. 골 성숙도 단계를 평가하기 위하여 수완부 방사선 사진은 Fishman이 제시한 skeletal maturity indicators(SMI)에 따라 평가되었고, 측방두부규격 방사선사진은 Baccetti가 제시한 cervical vertebral maturation(CVM) 방법에 따라 평가되었다. Spearman의 순위상관분석을 시행한 결과 치아 석회화 단계와 골 성숙도 간에 유의미하게 높은 상관관계가 나타났다(r = 0.40-0.84, p < 0.001). 7개의 영구치 중에서 하악 제2대구치가 골 성숙도와 가장 높은 상관관계를 보인 반면 중절치가 가장 낮은 상관관계를 나타내었다. 남녀 모두에서 하악 견치의 stage G와 하악 제2대구치의 stage F가 SMI 6단계와 CS 3단계에서 나타날 확률이 가장 높았다. 이 연구의 결과에 따르면 치아 성숙도와 골 성숙도 사이에 높은 상관관계가 있으므로, 파노라마 방사선사진에서의 치아 성숙도 평가는 성장기 아동의 골 성숙도를 평가하는 보조적 수단으로 활용될 수 있다. The aim of this study was to investigate the relationships between the stages of calcification of various teeth and skeletal maturity stages among Korean subjects. The samples were derived from hand-wrist, panoramic radiographs, and lateral cephalograms of 743 subjects (359 males and 384 females) with ages ranging from 6 to 14 years. Calcification of seven permanent mandibular teeth on the left side were rated according to the system of Demirjian. To evaluate the stage of skeletal maturation, hand-wrist radiographs were analyzed by skeletal maturity indicators (SMI) system of Fishman and lateral cephalograms by cervical vertebral maturation (CVM) method of Baccetti. Statistically significant relationships were found between dental calcification and skeletal maturity stages according to Spearman rank-order correlation coefficients (r = 0.40-0.84, p < 0.001). The second molar showed the highest correlation and central incisor showed the lowest correlation for female and male subjects. For both sexes, canine stage G and second molar stage F were related to SMI 6 and CS 3. Because of the high correlation coefficients, this study suggests that tooth calcification stages from panoramic radiographs might be clinically useful as a maturity indicator of the pubertal growth period in Korean patients.

[ $TiN_x$ ] powder have been fabrication by making of reaction between titanium powder and $Si_3N_4$ bowl during a planetary milling. Milling times were maintained for 1 hour, 5 hours, and 10 hours, respectively. The XRD result showed existence of non-stoichiometric compound of $TiN_{0.26}$ after 5 hours milling and coexistence of TiN with $TiN_{0.26}$ after 10 hours milling. Particle size distribution was investigated by particle size analyzer and microstructure was analyzed by FE-SEM. The size of titanium was decreased with increasing the milling time and the mean size of $TiN_x$ after 10 hours milling was increased by 200 nm. Planetary milling법을 사용하여 Ti 분말과 $Si_3N_4$ bowl과의 반응을 유도하여 $TiN_x$을 제조하였으며, 이때 milling 시간은 1시간, 5시간, 10시간으로 조정하였다. 시편의 물성평가는 X선 회절분석을 통해 결정상의 변화를 분석한 결과 milling 시간이 5시간이 되면 비화학당량적 화합물인 $TiN_{0.26}$가 먼저 생성되고 10시간의 milling에서는 $TiN_{0.26}$과 TiN이 혼재되어 있는 것으로 확인되었다. 입도분석 및 FE-SEM으로 미세구조 분석을 한 결과, milling 시간이 증가함에 따라 Ti 입자사이즈가 감소하는 것으로 나타났으며, 10시간의 milling에서는 평균사이즈가 200nm의 $TiN_x$를 제조할 수 있었다.

In this study, transparent conducting Al-doped Zinc Oxide (AZO) films with a thickness of 150 nm were prepared on corning glass substrate by the RF magnetron sputtering with using a Al-doped zinc oxide (AZO), ($Al_2O_3$: 2 wt%) target at room temperature. This study investigated the effect of rapid thermal annealing temperature and oxygen ambient on structural, electrical and optical properties of Al-doped zinc oxide (AZO) thin films. The films were annealed at temperatures ranging from 400 to $700^{\circ}C$ by using Rapid thermal equipment in oxygen ambient. The effect of RTA treatment on the structural properties were studied by x-ray diffraction and atomic force microscopy. It is observed that the Al-doped zinc oxide (AZO) thin film annealed at $500^{\circ}C$ at 5 minute oxygen ambient gas reveals the strongest XRD emission intensity and narrowest full width at half maximum among the temperature studied. The enhanced UV emission from the film annealed at $500^{\circ}C$ at 5 minute oxygen ambient gas is attributed to the improved crystalline quality of Al-doped zinc oxide (AZO) thin film due to the effective relaxation of residual compressive stress and achieving maximum grain size.

Recently the solution-based thin film technology has often been treated in the field of device fabrication owing to easy process and convenience for the development of various semiconductor devices and sensors. We deposited on glass substrate single-walled carbon nanotubes (SWNTs)/silane hybrid thin films by multiple spray-coating which is one of solution-based processes, and examined their electrical response for humidity. Generally silane binders which are often mixed in carbon nanotube (CNT) solution to adhere CNTs to substrate well form easily each own functionalized group on the surface of CNTs after they are hardened by way of the hydrolysis reaction. In this work, we investigated how silane binders (TEOS (tetraethoxy silane), MTMS (methyltrimethoxysilane) and VTMS (vinyltrimethoxysilane)) in CNT thin films make effect to their electrical response on humidity. As the result, we found that the resistance in the samples using TEOS was changed dramatically while it was almost invariant in the samples using MTMS and VTMS for increasing humidity.

태아기의 성 호르몬의 차이가 두 번째 손가락과 네 번째 손가락 길이의 비율을 비롯하여 여러가지 생리적 특성에 영향을 미칠 수 있다는 연구가 발표된 이후 관련 연구가 많이 진행되어 오고 있다. 그러나 우리나라 장애인을 대상으로 한 연구는 드물다. 이에 본 연구에서는 우리나라 장애인과 일반학생을 대상으로 손가락 비율 비교 및 장애인의 특성을 실증적으로 분석해 보았다. 그 결과, 장애인과 일반학생 모두에 있어 남자의 손가락 검지와 약지 길이 비율이 여자보다 낮아, 남녀별 성차가 있다는 일반적 사실을 확인 할 수 있었다. 다음으로, 남자와 여자 장애인 모두에서 나이대별 손가락 길이 비율은 통계적으로 유의한 차이가 없는 것으로 나타나, 일반인과 마찬가지로 장애인도 성장과정에서 검지와 약지 길이 비율이 크게 변하지 않음을 알 수 있었다. 마지막으로, 남자와 여자 지적 장애인 모두에 대하여 장애등급별 손가락 길이 비율도 통계적으로 유의하지 않은 것으로 나타난 바, 이로부터 손가락 검지와 약지 길이 비율이 장애여부와 관계가 있다는 점에 근거하면 현재의 장애등급 구분은 문제가 있다고 하겠다. Recent research has been mostly focused on the differences of prenatal sex hormone could affect the ratio of the lengths of the second to fourth digits (2D:4D) as well as the rate of several physiological characteristics. It has been suggested that digit ratios are thought to be associated with either higher prenatal testosterone levels or greater sensitivity to androgens, or both. However, a study of person with disabilities are rare in Korea. The purpose of this study was to compare patterns of the ratio (2D:4D) of the lengths of the second and fourth digits in persons with disabilities and students without disabilities. Also, we empirically analyze the characteristics of persons with disabilities. We found that finger length ratio (2D:4D) of men with disabilities and student without disabilities were lower than women with disabilities and student without disabilities. Therefore, it could be confirmed that finger length ratio (2D:4D) is sexually dimorphic trait. There were no correlations between finger length ratio (2D:4D) and age group in persons with disabilities. Therefore, as with person without disabilities, the 2D:4D ratio was negatively associated with a growth process of persons with disabilities. Finally, There was no difference correlations between finger length ratio (2D:4D) and level of disability in persons with intellectual disabilities. From this, one possible explanation for this is that if finger length ratio (2D:4D) is related to person with disability then current classification of the level of disability deserves further investigation.

Some seeds of the Rutaceae family, Zanthoxylum piperitum, Z. schinifolium, Evodio officinalis. Poncirus trifoliata, Citrus unshiu, were investigated to clarify their antioxidative components. Finely powdered samples were extracted by hexane, followed by dichloromethane and then 70% methanol in a hot bath. Its unsaponifiables containing α-and y-tocopherol with trace amount of β-and δ-tocopherol also showed comparatively weak activity. Levels of total tocopherols in the samples averages 42. 24-154. 11 mg/100g total extractives. The dichloromethane-and 70% methanol extractives showed strong antioxidative activity, from which antioxidative substances were purified with benzene-acetone(6 : 5. V/V) on a silica gel column, and with a solvent mixture of acetonitrile-methanol-H_2O(40 : 40 : 20, V/V/V) on a Sep-Pak C_18 hydrolyzed by 5% KOH-ethanol. The recovered unsaponifiables were then, separated on a column of high performance liquid chromatography. The unsaponifiables produced by hydrolysis of the isolates from dichloromethane extractives has epi-catechin(40.0~57.1%) and (+)-catechin(19.1~24.4% to total phenolic substances, on area base) as major component, accompanied by chlorogenic acid, gallic acid(?), trans-p-coumaric acid and trans-p-ferulic acid including some unknown components, and those derived from 70% methanol extractives also comprise (+)-catechin(31.3~39.6%) to total components. on area base), epi-catechin(20.2~36.4%), trans-p-coumaric acid(8.4~15.3%) and trans-p-ferulic acid(7.7~14.1%) as predominant component with some minor coponents, but the fraction supposed to be gallic acid(?) is not present. The antioxidative activities of the phenolic components isolated in this work were in order of epi-catechin>catechin>chlorogenic acid>trans-p-ferluic acid>trans-p-coumaric acid.
