목적 : 본 연구는 양안시기능이 정상인 대학생들의 읽기능력에 플러스렌즈의 착용이 미치는 영향을 알아보고자 하였다. 방법 : 안질환이 없고 양안시기능이 정상인 대학생 42명을 대상으로 조절래그와 읽기능력을 측정하였다. 조절 래그검사는 자각적 크로스실린더법을 사용하였고, 읽기능력검사는 Readalyzer를 사용하여 단어주시시간, 단어반 복보기횟수, 줄반복보기횟수, 읽기속도를 측정하였다. 대상자의 읽기능력은 조절래그량에 해당하는 플러스렌즈를 착용시키기 전과 후 각각 측정하였다. 통계처리는 SPSS version 21.0(SPSS Inc, Chicago, IL, USA)을 사용하여 플러스렌즈를 착용하기 전과 후의 변화를 대응표본 t-검정(Paired t-test)을 통해 분석하였다. 결과 : 대상자에게 조절래그에 해당하는 플러스렌즈를 착용시키자 착용하기 전에 비해 단어주시시간이 다소 증가하였고, 단어반복보기횟수는 유의하게 감소하였고, 읽기속도는 유의하게 증가하였다. 결론 : 독서 시 약한 굴절력의 플러스렌즈 착용은 단어를 주시하는 시간에 영향을 줄 수 있다고 사료된다. 독서 시 플러스렌즈 착용은 단어를 반복해서 보는 횟수를 줄이고 읽기속도를 증가시키는 것에 영향을 줄 수 있다고 사료된다.

목적 : 본 연구는 Tait-Wick과 Duke-Elder의 방법에 의한 시기능이상과 읽기능력의 상관성을 확인하고자 하였다. 방법 : 안질환이 없고 굴절이상이 완전 교정된 151명을 대상으로 Tait-Wick과 Duke-Elder의 방법으로 시기 능이상군의 종류를 나누어 읽기능력검사를 실시하였다. 시기능검사는 원‧근거리 수평사위도와 조절력, 폭주근점, 원․근거리 융합버전스, 조절용이성을 측정하였고, 읽기능력은 ReadAlyzer를 사용하여 단어주시시간, 단어반복보기횟수, 줄반복보기횟수, 읽기속도, 이해도를 측정하였다. 결과 : 폭주부족군은 정상군에 비해 유의하게 단어주시시간이 감소하였고(t=-2.423, p=0.019), 단어반복보기 횟수는 증가하였으며(t=4.770, p=0.000), 그 결과 읽기속도가 감소하였다(t=-5.674, p=0.000). 조절용이성이상군은 정상군에 비해 유의한 차이로 단어반복보기횟수가 증가했고(t=2.844, p=0.006), 읽기속도는 감소했다(t=-5.617, p=0.000). 다른 시기능이상군은 읽기요소에 대한 유의한 차이와 상관성을 보이지 않았다. 결론 : 폭주부족군은 독서 시 폭주가 충분치 않아 근거리 주시상태를 유지하기 어려워 단어주시시간이 감소하 고 단어를 반복해서 보게 되며 그 결과 읽기속도가 감소한 것으로 사료된다. 조절용이성이 작을수록 단어반복보기 횟수가 증가하고 읽기속도가 감소한 것으로 보아 검사거리가 40cm로 고정된 상태에서도 독서 시 미세한 조절자극의 변화가 발생하였고 이에 대한 부적응이 일어난 것으로 사료된다. 일부 시기능이상은 읽기의 운동적 요소에 영향을 미칠 수 있으나 인지적 요소에는 영향을 주지 않는다고 사료된다.

목적: 본 연구는 시기능이상과 읽기능력변인의 상관성을 알아보고자 하였다. 방법: 교정시력 1.0 이상인 평균나이 22.74세 남녀 120명을 대상으로 양안시기능과 읽기능력변인을 검사 하였다. 양안시기능검사는 원,근거리 수평사위, 폭주근점, 조절용이성을 측정하였고 임상기준값에 의해 정상군과 이상군으로 분류하였고, 읽기능력변인의 종류는 읽기속도, 주시횟수, 주시시간, 주시반복횟수, 이해도, 읽기등급이며 VisagrapⅡ(ReadAlyzer)를 이용해 검사하였다. 읽기능력변인에 대한 시기능이상군과 정상군의 차이는 독립표본 t-검정(Independent t-test)로 평가하였고, 시기능이상의 정도에 따른 읽기능력변 인의 상관성은 Pearson`s 상관분석을 통해 분석하였으며 유의수준은 p < 0.05로 하였다. 결과: 원·근거리 모두에서 외사위군은 정상군에 비해 읽기속도는 감소하고, 주시횟수는 증가하였으며(p < 0.05), 근거리 외사위군에서는 사위도가 증가함에 따라 읽기속도가 감소하였고, 주시반복횟수의 증가로 인해 읽기등급이 감소하였다(p < 0.05). 조절용이성은 이상군이 정상군에 비해 읽기속도가 더 느렸고(p < 0.05), 조절용이성이 증가함에 따라 읽기속도가 증가하였다(p < 0.05). 결론: 주시거리에 관계없이 정상범위를 벗어난 외사위안은 내사위안보다 읽기능력에 더 큰 영향을 미쳤으며 이는 독서 시 요구되는 폭주량이 내사위보다 외사위에서 더 크기 때문이라 사료된다. 일부 시기능이상은 읽기속도 등의 읽기능력변인에 영향을 줄 수 있으나 다른 변인과 상관성이 없다면 읽기능력에 미치는 영향이 미미할 것이라 생각된다. 따라서, 읽기능력을 향상시키기 위해서는 외사위와 조절용이성 이상을 교정 할 필요가 있다고 사료된다.

Building cities with a cultural identity consists in making cities, which are not unified and standardized but differentiated. As methods for creating the identity of a city, tradition-based urban design and architectural design are effective. Essence is at once crucial value and identity. That is why the identity of architectural culture is important. As the first project for understanding the identity of architectural culture, we need to understand traditional architecture. Around us, we have countless architectural works worth scrutinizing for such understanding. Hanok is an interesting topic for all Koreans. Any Korean who wants to learn more about hanok can easily get books on it. They include books written by a master carpenter, an architecture professor, an architect, and a writer. And those books treat a general overview of hanok, focus on such design elements or architectural elements as materials, colors, wooden structure, discuss the principles of hanok, describe hanok building, or address royal palaces and traditional hanok. We should build the ability to lead the global architectural culture by fusing together the merits of the Western architectural culture and those of our architectural culture and thereby developing another version of our unique culture. A lot ofleaming is required to create Korean architectural culture as the 'only one'. Study is about training to know relationship. The relationship among people and the relationship with nature which appear in space constitute the essence of our architecture.

Coal briquette ash is an inorganic and non-combustible material. Although coal briquette ash is mainly composed of SiO2, Al2O3, and is an acceptable raw industrial material (containing Fe2O3, K2O, MgO, CaO, TiO2, and Na2O), it is merely considered waste and is exploited as a building material for concrete admixtures and bricks. Because mullite (3Al2O3 2SiO2), which coal briquette ash contains, is a stable compound with a crystalline structure, it plays essential roles in its fracture strength and bending strength. This study serves the purpose of developing environmentally friendly, economical clay bodies through the use of coal briquette ash as a substitute for kaolin to provide Al2O3 and SiO2. We also investigated the seed effects during sintering process by feeding mullite directly into clay bodies. The results show that in 1,300°C heat, a mixture of 40% coal briquette ash, 40% feldspar/limestone (8 : 2), and 20% clay indicates a fracture strength value of 525 kgf/cm2, an absorption rate of 0.72%, burning shrinkage of 11.5%, and an average bending strength of 0.6 cm, which is superior to other clay bodies. The addition of coral briquette ash in clay bodies promoted mullite formation and grew as mullite acted as a seed. In addition to the developing clay bodies, it can also make an oatmeal-colored glaze to widen the spectrum of its usability. This study will help resolve waste problems, reduce environmental pollution, and raise economic value by using coal briquette ash as a raw material for ceramics. Clay bodies made with coal briquette ash are expected to continuously contribute to the development of the ceramics industry with upcycling effects.

Waterworks sludge is currently disposed after being used in water treatment, spending enormous cost. In order to protect the environment and avoid wasting, this study aims to develop high-temperature clay bodies using waterworks sludge for art tiles. As starting materials, feldspar, clay, and waterworks sludge, in place of silica, were used by triangular coordinates. According to the results indicated, the 40% sludge contained bodies showed good results which have low water absorption and high fracture strength in physical properties and color for art tile. The result of analyses showed mainly mullite and anorthite were developed in the bodies. Addition of Ca volume or firing at the higher temperature promoted the formation of anorthite and improved the strengths of the body. When mullite and anorthite coexisted in the bodies, fracture strength and water absorption showed maximum value, but overuse of Ca caused growth in porosity and absorption. The body color was affected by color development of iron. When mullite was doped by Fe3+ hematite appeared red and then increase of anorthite by addition of Ca, the magnetite was detected in the body and they appeared from dark gray to black shade color. Bodies of art tiles using recycled waste materials and waterworks sludge showed comparative properties such as strength, absorption, and bending strength to those of traditional tiles.

Somaclonal variation, defined as phenotypic and genetic variations among regenerated plants from a parental plant, could be caused by changes in chromosome structure, single gene mutation, cytoplasm genetic mutation, insertion of transposable elements, and DNA methylation during plant regeneration. The objective of this study was to evaluate DNA variations among somaclonal variants from the cotyledonary node culture in soybean. A total of 61 soybean somaclones including seven ~textrmR1 lines and seven ~textrmR2 lines from Iksannamulkong as well as 27 ~textrmR1 lines and 20 ~textrmR2 lines from Jinju 1 were regenerated by organogenesis from the soybean cotyledonary node culture system. Field evaluation revealed no phenotypic difference in major agronomic traits between somaclonal variants and their wild types. AFLP and SSR analyses were performed to detect variations at the DNA level among somaclonal variants of two varieties. Based on AFLP analysis using 36 primer sets, 17 of 892 bands were polymorphic between Iksannamulkong and its somaclonal variants and 11 of 887 bands were polymorphic between Jinju 1 and its somaclonal variants, indicating the presence of DNA sequence change during plant regeneration. Using 36 SSR markers, two polymorphic SSR markers were detected between Iksannamulkong and its somaclonal variants. Sequence comparison amplified with the primers flanking Satt545 showed four additional stretches of ATT repeat in the variant. This suggests that variation at the DNA level between somaclonal variants and their wild types could provide basis for inducing mutation via plant regeneration and broadening crop genetic diversity.
