This experimental studies were conducted to clarify the effects of selection, and aimed at estimating genetic parameters such as, gene action, combining ability and heritability on three agronomic characters in Cowpea (Vigna sinensis Savi.). The six different parents and 15 F_2 hybrids by 6×6 diallel crosses were used as materials, and were planted in a randomized block design with three replications. The results obtained are summarized as follows : 1. Vr-Wr graphic analyses Length of pod stalk was found to be inherited in over dominance. and length of pod and seed numbers per pod were inherited in partial dominance. 2. Components of variance: Estimates of additive components of variances were greater than those of dominance components of variances for length of pod and seed numbers per pod. Negative values of F were estimated for two characters, length of pod and seed numbers per pod. The highest heritability value was found in length of pod, but the value of seed numbers per Pod was the lowest. 3. Combining ability analyses: The mean squares of general combining ability for length of pod and seed numbers per pod were higher than those of specific combining ability. 4. Effects of combining ability: The high GCA effects were expressed by variety TVu1857 in length of pod stalk and seed numbers per pod, variety TVu2885 in length of pod. The high SCA effects were exhibited in the hybrids between TVu1857×J78 and TVu2885×J80 in length of pod stalk and seed numbers per pod, TVu1857×TVu2885 and TVu2734×TVu2885 in length of pod. Therefore, it can be concluded that TVu lines could be the useful varieties in cowpea breeding for long pod and high yielding.

A reconfigurable bus system is defined to be a bus system whose configuration can be dynamically changed by establishing the local switch of eath processor. A processor array connected to a reconfigurable bus system is defined as a processor array with a reconfigurable bus system. Two constant time algorithms are presented for linking the non-zero terms in a binary sequence and for computing the histogram of an image on a processor array with a reconfigurable bus system, respectively. Then, these two algorithms can be used to compute n angles of the Hough transform of an image with N edge pixels in constant time using O(nN³) processors.

The purpose of this study was to investigate the changes of polished and caries enamel of third molar when they were irradiated by the CW Nd : YAG laser with optical fiber delivery system and the pulsed Nd:YAG laser. The author investigated the hardness of lased enamel surfaces with the energy density of 40 J/㎠ and the shear bond strength between etched enamel and composite resin, and examined the polished and caries enamel surfaces irradiated by CW Nd : YAG laser with the energy density of 20-120 J/㎠ by using scanning electron microscope. The obtained results were summerized as follows : 1. The Knoop hardness decreased significantly after irradiating the Nd : YAG laser with the energy density of 40 J/㎠(P<0.01). 2. The shear bond strength of enamel showed a significant difference before and after irradiating the Nd : YAG laser with the energy density of 40 J/㎠(P>0.05). 3. SEM photographs showed the irregular microcracks and the structural change of lased enamel surface. 4. SEM photographs showed the aspect of decrease in decalcification of enamel prism after irradiated with the energy density of 40 J/㎠. 5. SEM photographs showed the aspect of removal in caries enamel when they were irradiated with the energy density of 70 J/㎠.

We performed silicon-to-glass bonding using silicon direct bonding followed by anodic bonding(SDAB). Initial bonding between glass and silicon was caused by the hydrophilic surfaces of silicon and glass ensemble using silicon direct bonding(SDB) method. We found that the bonded specimen using SDAB process had higher strength than one using anodic bonding process only. We performed multiple layer bonding by SDAB, which is glass- silicon -glass as sandwich structure. In the silicon wafer, the (1mm x 2mm x 500μm)-sized cavity was formed by the anisotropic etching of the silicon substrate in EPW(Ethylendiamin-Pyrocatechol-Water). And, the cavity was sealed with glass wafers by SDAB method.

Silicon-to-silicon anodic bonding was accomplished using lithium doped interlayer. Lithium doped interlayers were deposited on silicon substrates by electron beam evaporation, which has a fast deposition rate compared with sputtering method. Silicon-to-silicon bonding occurs in the range of temperatures from 250℃ to 300℃ with the applied voltages from 70V_(DC) to 100V_(DC). The bonding strength obtained from tensile test was about 5MPa under the condition of 80V_(DC) in 300℃. The surface morphology of lithium doped interlayer was studied with the atomic force microscopy (AFM). Finally, secondary ion mass spectroscopy (SIMS) analysis was carried out in order to investigate the role of the lithium ions in bonding mechanism.

치과 방문 시 어린이와 부모의 치과 불안도의 상관 관계

김성희,백병주,김재곤,양연미,권병우 大韓小兒齒科學會 2005 大韓小兒齒科學會誌 Vol.32 No.2

어린이에게 있어서 치과 불안의 문제는 오랫동안 환자 행동조절의 문제로서 여겨져 왔으며 이러한 문제로 인해 치료 시의 비협조도, 치료 악속 취소 및 회피 둥이 발생할 수 있다. 따라서 치과의사 및 치과 팀에게 가능한 한 빨리 어린이의 치과 불안을 인지하여 적절히 대처할 것이 요구 되어진다. 한편, 부모의 치과 불안이 그들의 아이의 치과 불안과 치료 협조도에 영향을 줄 수 있음이 이전의 여러 연구들로부터 언급 되어지고 있다. 또한 치과 방문 결정의 주체가 어린이라기보다는 부모임을 고려할 때, 부모와 어린이 사이의 치과 불안도의 관계 규명이 중요하다 하겠다. 본 연구는 전북대학교 병원 소아치과에 내원한 3~10세(평균 연령 5.27세, 표준 편차 2.172세)의 어린이 78명(남아 45명, 여아 33명)과 그들의 부모 78명을 대상으로 하였으며, 치과 치료 전의 어린이의 치과 불안도 평가를 위해 Venham Picture Scale을, 부모의 치과 불안도 평가를 위해 Corah's dental anxiety scale을 사용하여 두 값을 비교하였다. 또한 어린이의 치료 시 협조도, 기질, 성별, 나이, 부모의 교육 정도를 평가하여 치과 불안도와 비교하였다. 이에 다음과 같은 결론을 얻었다. 1. 어린이의 치과 불안도와 부모의 치과 불안도 사이의 상관 분석 및 회귀분석에서 상호 관계성이 존재하였다(P<0.02). 2. 어린이의 치과 불안도와 치료 협조도사이의 상관 분석 및 교차 분석에서 음의 상호 관계를 나타내었다(P<0.001). 3. 어린이의 치과 불안도와 기질에 관한 Student's t-test에서 낮은 불안도와 높은 불안도 그룹의 네 가지 기질 평균 점수비교 시, 낮은 불안도 그룹에서 모두 약간 낮은 평균 점수를 보였으나 통계학적 유의차는 없었다(P>0.1) 4. 어린이의 치과 불안도와 어린이의 성별, 나이에 관한 Student's t-test에서, 여아에서 높은 불안도, 3~6세의 어린 그룹에서 높은 불안을 보였다(P<0.001). 5. 부모의 치과 불안도와 부모의 학력에 관한, Student's t-test에서, 대학교육을 받지 않은 저학력 부모 그룹에서 더 높은 불안도를 보였으나 통계학적 유의차는 없었다(P>0.1). In children, dental anxiety of dental treatment has been recognized as a source of problems in patient management for many years. Dental anxiety can be causes of negative cooperation, cancel and avoid of dental treatment. Therefore, dentist and dental team should recognize of child's dental anxiety as early as possible and manage appropriately. In previous studies, it is reported that parental dental anxiety affect dental anxiety and cooperation of their child. And it is parental decision which results in a child's visit to the dentist, rather than a child's decision in most cases. Therefore, it is important to identify the relationship of dental anxiety between child and parent. We estimated child's dental anxiety before dental treatment using Venham Picture Scale that is useful even a very young child and parental dental anxiety using Corah's dental anxiety scale. Then, two values above were compared. Child's cooperation, temperament, sex, age, parental education were estimated and compared with dental anxiety, too. The results were as follows: 1. There are positive relationship of dental anxiety between child and parent with the correlation analysis (P<0.02). 2. There are negative relationship of child's dental anxiety and child's cooperation with the correlation and regression analysis (P<0.001). 3. Low anxiety group has lower mean value of four temperament item with the Student's t-test. But, there is no statistical differences (P>0.1). 4. Girl and younger group have higher mean value of dental anxiety than boy and older group with the Student s t-test (P<0.001). 5. Low educated parents have higher mean value of dental anxiety than high educated parents with the Student s t-test (P>0.1).
