The purpose of this study is to find framework schema of early J usimpo-style Buddhist halls (Geungnakjeon Hall of Bongjeongsa Temple, Muryangsujeon Hall of Buseoksa Temple, and Daeungjeon Hall of Sudeoksa Temple). Though the halls are known as built in the late Goryeo Period, they show the influence of the architectural style of the early Unified Silla Period. To find the adopted modules and proportions of these halls, this study conceived a schematic diagram based on the whole frame structure taking reference from the Cai-Fen system in Yingzao Fashi. In these three halls, the heights of each cross-beam (Dori) are made up by the layers of member and member units. This study computes the values of Cai, Zhi, and Fen which can apply to both the section and the plan. The vertical section structure is determined by combining the standard member heights (Cai) and the standard unit heights (CaiZhi). The bays of columns are made by multiples of the standard member width (Fen).

In order to grasp and evaluate the characteristics and the safety of traditional wooden building, we select one of the representative traditional wooden building, Buseoksa Muryangsujeon in this study. After the two and three-dimensional structural analysis of this building are performed, the results are compared and analyzed. Following main conclusion are obtained: 1) By comparison between the results of two and three-dimensional structural analysis, they show that the exterior members of this building tend to transfer more load in the three-dimensional analysis. 2) The result of three-dimensional structural analysis shows that the every member stress of Buseoksa Muryangsujeon except Chobang and Jangyon is below allowable stress. 3) For exact modelling of joints of members in traditional wooden building such as Gongpo, it is necessary to accumulate and analyze the technical data through structural test and systematic analysis study.

농업이 기간산업이었던 고대사회에서 수리시설(水利施設)의 축조는 농업의 성패를 가늠하는 중요한 요소로 정치 경제 사회 전반에 걸쳐 큰 영향을 미치는 국가적인 대규모 사업이었다. 이에 따라 수리시설의 축조 시기와 배경, 축조 기술과 운영, 구조, 몽리(蒙利) 효과 및 보수(補修)와 수축(修築) 등에 대한 연구는 우리의 농경(農耕)문화사를 밝히는데 중요한 관건이 된다. 관개(灌漑) 수리시설의 축조와 정비는 수전(水田) 개발과 밀접한 연관이 있다. 제방(堤防)을 축조함으로써 주변의 수전 개발을 촉진하고, 가뭄과 홍수로부터 안전하게 전답을 유지할 수 있어 수확량을 높이게 된다. 농업생산력의 향상은 대내적 체제 정비는 물론 치열한 국가 간의 경쟁에서 우위를 점하는데 필요한 경제적 배경이 된다. 이처럼 고대수리시설은 개인과 집단 나아가 국가의 생존을 뒷받침하는 근본이었지만, 과연 우리는 그 역사성과 의미에 대해 제대로 평가를 했던 것일까? 또한, 고대수리시설의 관개 및 치수(治水) 능력은 구체적으로 어느 정도였으며 근대에 비하면 어느 정도였을까? 일부 수리시설에 대해 관개면적을 추정한 경우는 있으나, 그 예도 많지 않을뿐더러 시기적인 변천 양상을 제대로 반영하고 있지 못하는 것이 현실이다. 본 연구는 고대로부터 원형을 비교적 잘 간직하고 있는 수리시설 중 경북(慶北) 영천(永川)의 청제(菁堤)를 대상으로 고고학적 역사학적 입장에서 보다는 수문학적(水文學的) 농업수리학적(農業水利學的) 관점에서 저수량(貯水量) 및 관개(灌漑) 면적에 따른 농업생산력을 살펴보았다. 지형 및 GIS (Geographic Information System) 정보를 이용하여 저수지의 규모 및 관개 면적을 추정하였으며 수문학적 해석 모형(模型)인 CAT(Catchment hydrologic cycle Assessment Tool)(김현준 등, 2012)을 이용하여 저수량 및 관개 가능량을 분석하였다. CAT은 공간 단위별로 침투(浸透), 증발(蒸發), 지하수(地下水)흐름 등의 모의(模擬)가 가능하도록 개발된 모형이다. 특히, 농업용 저수지 및 홍수방재용(洪水防災用) 저류(貯留)시설 등의 저류량(貯留量) 및 방류(放流量)에 대한 모의가 가능하다(장철희 등, 2012). 고대수리시설의 저수량 및 관개 면적에 따른 농업생산력을 공학적 수문학적으로 해석하는 연구는 과거물 관리 및 생산력의 실태를 좀 더 자세히 파악할 수 있는 토대가 될 것이며, 역사학적 자료와의 비교 분석을 통해 우리나라 고대수리시설의 역사성 및 우수성을 찾을 수 있을 것으로 판단된다.

Experiments were conducted to study the effect of stage of maturity at harvest on the quality of silage. Herbage samples taken from the barley plant, rye plant, wheat plant, oat plant, Orchardgrass, Italian ryegrass, a mixed grass sward of Orchardgrass and Italian ryegrass and corn plant at different stages of maturity and ensiled in order to evaluate the effect of maturity on the chemical composition and feeding value as well as digestibility using sheep. Forage material were ensiled in small concrete silo. 1. The dry matter yield per 10a increased with advancing the maturity. Yield of brarley plant was 404, 635 and 900 kg at heading, milk and milk dough stage, respectively. Rye plant yield was 279, 589, 708, 10,000, 1,265, 1,376 and 1,492 kg at booting, before heading, early heading, late heading, early flowering, late flowering and after flowering stage, respectively. Italian ryegrass yield was 355, 613, 844 and 1,109 kg at vegetative, booting, heading and flowering, respectively. Orchardgrass/Italian ryegrass production was 477, 696, 891 and 1,027 kg at before was 458, 1,252, 1,534, 1,986 and 2,053 kg at tassel, early milk, yellow ripe and ripe stage, respectively. 2. Dry matter content increased with advancing maturity, but crude protein declined markedly. The NFE content decreased with advancing maturity of all the herbages except corn plant where NFE content increased, but corn plant increased. The content of crude fiber increased with advancing maturity except corn plant. The content of crude ash decreased with advancing maturity. In the rye plant, the content of neutral detergent fiber (NDF), acid detergent fiber (ADF) and cellulose increased with advancing maturity. 3. In vitro dry matter digestibilities of the rye plant was 53.6, 54.1, 50.7, 47.1, 44.9, 40.1 and 38.9% booting, before hcading, early heading, late heading, early flowering, late flowering and after flowering stage, respectively. The regression equation was $Y=56.22-0.74X+0.009X^2$ (X=cutting date from the first cut, Y=dry matter digestibilities). 4. In vitro digestible dry matter yield (kg/10a) of rye plant increased with advancing maturity, but declined from the flowering stage. The regression equation was $Y=168.88+26.09X-0.41X^2$ (X=cutting date from the first cut). 5. In vitro digestibility of dry matter in the corn plant was 69.2, 71.5, 69.8 and 69.9% at tassel, early milk, milk and yellow ripe stage, respectively. 6. The digestibility of crude protein and crude fiber of all plants decreased with advancing matuity, but NFE of the barley and corn generally increased. 7. The TDN contents on the dry matter basis decreased, but those of barley and corn silage were not different. TDN content of barley was 57.8, 57.1 and 57.9% at heading, milk and milk dough stage, respectively. That of rye silage was 50.0, 27.2 and 43.7% at early flowering, after flowering and milk stage, respectively. Italian ryegrass silage was 67.9, 63.7, and 54.9% at before heading, early heading and after heading, respectively. In case of Orchardgrass silage the TDN was 54.8, 52.9 and 46.1% at after heading, after flowering and milk, respectively. Corn shows TDN value of 59.5, 62.8 and 61.6% at milk, yellow ripe and ripe, respectively. 8. The pH value increased slightly by advancing maturity. 9. the content of organic acid decreased by advancing maturity and also increasing the DM content.

Architecture is usually seen as a product of art and technology. However, most historical buildings also exemplify various sophisticated principles of mathematics. Outstanding examples of architecture around the world such as Seokguram, Daewoongjun of Bulguksa, Muryangsujeon of Buseoksa, and the Parthenon provide students with a great opportunity to study their underlying mathematical properties and principles. The activity of identifying and investigating such mathematical principles in historical buildings enables students to realize that mathematics is a practical subject, and thus provides justification for the study and importance of mathematics. For the purpose of this study historical architecture was reviewed with this in mind in order to develop STEAM education materials focused on elementary school mathematics. The result of this study is as follows: first of all, appropriate examples of historical architecture were selected on the basis of the 2009 revised curriculum's content and teaching goals. These involved chapters on 'proportion', 'symmetry', 'movement of figures', 'building blocks', and 'triangles'. Secondly, a meta-analysis was performed on the historical buildings that clearly illustrate mathematical principles. Thirdly, STEAM education materials focused on elementary mathematics using architectural examples were developed which made actual application in classrooms possible. And lastly, surveys of professional groups were conducted to verify whether the produced materials were suitable teaching resources.

It is the purpose of this study to arrange in ornamental trees and shrubs the planting that leads to an appropriate type of templescape. The study was designed primarily as an examples for each Buddhist temple which desires further decoration with several ornamental plants, doubles the effectiveness of the Sen-Buddhist meditation, and boosts tourists' attraction. To investigate the planting status and type of trees and shrubs in the precincts of Buddhism temples, We close three temples : They are Nagsansa, Boolgoogsa and Booseugsa, which are intermonatane area temples all together. The results investigated were summarized as follows :1. Planting status and pattern in temples Open spaces of the Daewoogjeon in all temples, a main Sanctuaries in temple buildings, where Buddha is enshrined in, we could not find any kind of trees of shrubs to be planted.Muryangsujeon, a symbol of "Future", which can be also found at Boosugsa temple, is living in Western Elysium world and takes mercy on mankind of this life. Taxus cuspidata was planted at this Muryangsujeon, known as an immeasurable bliss building, where an Amitabha is enshrined in.Total 25 species of trees and shrubs were planted around Birozani building of Buddhist temples, Birozani is enshrined at the Birojion of Boollgoogsa temple.The buddhist Goddess of Mercy which is a buddhist saint for pursuit of fortune and blessing to relieve the mankind is enshrined at Wonchonjeon, Daebijeon and Kwaneumjeon which are able to observe at both Boolgoogsa and Nagsnsa temples, where Euonymus japonicus trees including other 26 species could be found in common at both temples.2. Correlation between trees/shrubs and temple buildingsTrees and flowers symbolizing Buddha are often planted as material sources of gardening to decorate : They are Logerstroemia indica as Buddha's flower, Viburmum opulus var. calvescens resembling Buddha's head, Tilia mandshurica producing the beads of rosary, Gardenia jaminoides Ellis with white flower blade and flower of bliss, not flower to this day and Lotus flowering clearly in the pond filling with dirty water which is able to clarifies the world full of crime, infidelity and injustification. Among these Buddhist' plants, however, Logerstroemia indica could be found in all three temples, and Viburmum opulus var. calvescens at both Nagsansa and Boosugsa. Also, Lager stroemia indica was planted at all three temples and Viburmum opulus var. calvescens at both temples of Nagsansa and Boosugsa. Tilia mandshurica and Gardenia jasminoides Ellis were not found in any temples which might become the subject of investigation.In relation of the buildings of each temples as a sanctified space, the planting of trees and shrubs was not considered for the arrangement, templescape architecture or species. And, also, we could not find in the study any special relationship of trees/ shrubs with the characteristics of temples.With the results obtained through precise studies we presented here in this paper newly designed model of templescape in intermane buddhist temple which can be applied for planting and arrangement of trees or/and shrubs. Basic principles of model in mind are:To consider the correlation of the dominant between plants and temple buildings.To plant trees/shrubs for special functions as well as conditions of temple location.To make tree arrangement correlating to Buddhism spirit.To induce environment friendly plants to be planted, suitable to regional conditions.This redecorated model of templescape might be used as a canon of the tree planting and arrangement in the precincts of Buddhism temples.

Hot tub lung has been described as a pulmonary illness associated with exposure to nontuberculous mycobacteria,mainly hot bathtub water contaminated with Mycobacterium avium complex (MAC) and hence the name. Although not entirely clear, its etiology has been thought to involve either an infection or a hypersensitivity pneumonitis secondary to MAC. Herein, we describe 2 female patients (60 and 53 years old) admitted to our hospital with hot tub lung, and both of whom worked in a public bath. Both women were initially admitted following several months of exertional dyspnea and cough. The patients had been working as body-scrubbers in a public bath for several years. Their chest CT scans showed bilateral diffuse ground-glass opacities with multifocal air-trappings and poorly defined centrilobular nodules in both lungs. Pathological findings from lung specimens revealed small non-necrotizing granuloma in the lung parenchyme with relatively normal-looking adjacent alveoli. Discontinuation of working in the public bath led to an improvement in symptoms and radiographic abnormalities, without antimycobacterial therapy.

Seok Jeon Hwang Wook (18913~1999), a descendant of a traditional literary writer in the western part of Honam, did not join the flow of modern and contemporary calligraphy and painting. And throughout his life, he enjoyed himself without losing the appearance of a scholar, immersed himself in traditional calligraphy, and gained spotlight at his late age for his original hand grabbing calligraphy. Immediately after the Korean War, all of his property was lost due to his two sons' left-wing activities, causing great pain at home. Even in the most painful and difficult time in human history, he relied on brushes, poetry, and gayageum to keep his upright scholarly spirit and national love. And beyond the pleasures of the worldly senses, he played with self-satisfaction in the 'true pleasure(大樂)' without greed. In the course of his studies, he focused on honing the fonts of Wang Hui-ji, Gu Yang-sun, An Jin-gyeong, Jo Maeng-bu, and Xin-wi and Lee Sam-man without a special teacher. In particular, he faced a crisis of having to give up his brush due to tremor that came after his 60th birthday, but he showed a strong will. He transformed it into a new style of art, such as developing hand grabbing calligraphy(握筆法) with a strong and strong energy that no one could match. From 1965 to 1983, 'right hand grabbing calligraphy' was used, and from 1984 to 1993, 'left hand grabbing calligraphy' was used. She made her name as a calligrapher widely known in 1973 (age 76) with her first solo exhibition, The Calligraphy Exhibition commemorating her 60th wedding anniversary. His writing method is naturally rough and sloppy by breaking away from the previous calligraphy methods and artificial technique, and is unfamiliar yet full of muscle. And the calm, strong and rough chuhoegsa(錐劃沙) and the heavy yet majestic ininni(印印泥) individual handwriting expressed a strange feeling and achieved original Seokjeon calligraphy that went beyond the existing calligraphy writing methods, and his indomitable calligraphy spirit was As a unique existence in the history of calligraphy, he still remains as a model.
