        As it is known, during the Second World War Greece has fought on the side of theallies and the end of the war found the country on the winners’side. However, thestruggle for authority right after 1945 was merciless and extremely difficult, as well asdangerous for the course of the country to the future. The political powers were dividedbetween the legal authorities that were represented by the king and formed the exiledgovernment on the one hand and the part of the resistance teams and the rebels of the leftthat had a soviet friendly direction on the other. Thus, the start of a civil war was just a matter of time. It finally started in 1947 andlasted for more than two years. The consequences were disastrous for the country’seconomy and decisive for the future course of Greece. The national army prevailed withthe help of, mostly, the English. Royal parliamentary democracy was established with aclear political turn to the west, as a completion and adaptation of the Agreement of theGreat Powers at Yalta. Art had a ‘similar’route. Dipolar, contradictory: conservative choices on the oneside, and a will for pioneering inspiration and perspective on the other side. The‘dominate’trend was first evident in sculpture and mainly in the public monuments. Theirconstruction aimed mostly at the public propaganda and at the promotion of the sovereignideology. On the one side we have the public sculptures composed of faces of contemporaryheroes or leading figures of the civic war and the national resistance. On the other side wehave monumental statues mainly that appeal to a ‘public’outside of the country’s bordersand mostly of the north borders, where there are countries with a communistic regime, likeBulgaria, Serbia and Albania. Their subject is derived from the heroic events of the BalkanWars (1912-1913) and ancient historical figures like Alexander the Great as the Greek armyleader, his father, Philippos II and Aristotle, who was of a north-Greek origin. The political message is twofold: on the one side the ‘inner enemy’the communiststhat were defeated and the promotion of the new liberal social system and on the otherside the north neighbours, which not only represent the East Block, but they also conspire the history and the culture of the Greeks. This is the way how the ‘Cold War’was resultedin a full and totalitarian expression in art.

        Treatment of water hyacinth with sulphuric acid produces carbonaceous materials that have been used to remove Cu(II) and Cd (II) ions from aqueous solutions. Untreated water hyacinth was also used for the subject of comparison. The textural properties of the carbonaceous materials were determined from nitrogen adsorption at 77 K. The optimum pH for the sorption of Cu (II) and Cd (II) ions on the investigated sorbents was determined. Dynamic adsorption measurements have been taken at 298 K whereas equilibrium measurements were carried out at 298, 313 and 323 K. The adsorption of nitrogen at 77 K on the untreated sample was too low and the surface areas of the treated samples 2, 3 and 4 were found between 70-208 m2/g. The total pore volumes of these samples which were determined for the carbonaceous materials investigated were found to be 0.076-0.140 ml/g. The kinetic adsorption data of Cu (II) and Cd(II) were applicable to both pseudo - first and pseudo-second order but fit more the latter order. The equilibrium adsorption data were found to fit Freundlich and Langmiur equations. The values of DG, DH and DS are all negative indicating the feasibility and the spontaneous nature of the sorption of Cu (II) and Cd (II) ions by the sorbents investigated.

        Throughout Yeats's life, his occultism absorbed much of his time and energy. Yeats's occultism supported and enriched his poetry and plays, providing him with themes, the symbols, a philosophy that affirmed recurring self-renewal. Through the development of Yeats's occult thinking, from the Golden Dawn, through Per Amica Silentia Lunae, to A Vision, a continuous, coherent direction can be traced. Books II and III of A Vision, deal with the nature of the human soul, its different principles, and its progression after death. In "The Completed Symbol," Yeats elaborates on the Four Principles of the soul ― the Husk, the Passionate Body, the Spirit, and the Celestial Body. The Principles find their Unity in the Celestial Body, man's archetype in Heaven. In "The Soul in Judgement", examining the six after-death states, death, in general, is also presented as a transfer of consciousness from the physical plane to a higher one. During the first three states, or until Beatitude, the Spirit passes each time into a higher state of consciousness; after Beatitude, following the circular pattern of "The Great Wheel," the Spirit lapses slowly into relative unconsciousness. These six states, like the twenty-eight phases, affect each other, and in each one the Spirit has to act under certain laws. The soul has to pass through all of these states in order to progress and to prepare for its reentry into the physical world. This belief in the six after-death states stems from the occult sources mainly Theosophy which also teaches that the soul passes through six planes of consciousness after death -- the divine, the monadic, the spiritual, the intuitional, the mental, and the astral plane or plane of passions and emotions. Yeats uses the lunar cycle to explain the soul's journey between lives. The concept of the Thirteenth Sphere is important because in the occult traditions, the number thirteen is also symbolic of unity and perfection. In A Vision the Thirteenth Sphere represents Unity since in it all antinomies are resolved. Yeats's view of the soul is directly related to his belief in a universal duality ― the existence of opposite but equal forces that dominate a cycle alternately.

        Objective: <千金方(Qianjinfang)> which documents a great amount of prescription of Acupuncture and moxibustion bikes an important role during the development of acupuncture and moxibustion. Thus, it have given rise us to the research-situation of Tang Dynasty China of previous period. This study was to outline the rules of choosing acupoints as well as the prescriptions of contemporary times in reference with <千金方(Qianjinfang)>, and to discuss the conception of acupuncture and moxibustion in <千金方(Qianjinfang)>. Method: Based on <千金方(Qianjinfang)>, the parameters were categorized to a certain scope, syndromes in different type were classified. Also numbers of acupoints, route of meridians locations, utilities of special acupoints even prescription methods were statistically analyzed in reference with <千金方(Qianjinfang)>. Results & Conclusion: Acupuncture prescription in <千金方(Qianjinfang)> was mostly presented by single acupoint and this was basic prescription of its rule of choosing acupoints. Choosing acupoint for the majority of various diseases started from choosing meridians with the disorder, but no rules for choosing acupoints was clear. There was basically various methods in choosing acupoints, but little were used by Biao-Ii meridian choosing method (表裏經配穴.) In the high frequency of use, wu-shu acupoints was higher used than other specific acupoints (特定穴). While wu-shu acupoints treated the major parts of the diseases, shu-mo acupoints were strictly used on system. Consequently : The theoretical basis originating the choosing rules of the acupoints and prescriptions was shown in <千金方(Qianjinfang)> as representative clinical reference, through which it was valuable to analyze the prescription rule and specificity of the acupoints.

        목적 : 발달지연 아동들에게 Capute와 Bayley 발달검사를 실시하여 뇌성마비 감별에 이들 지수들의 유용성을 평가하고, 이들 검사 중에 뇌성마비를 가장 잘 감별할 수 있는 발달검사 척도를 찾아 뇌성마비 아동을 조기에 진단하고 재활중재와 개입전략을 세우는데 도움이 되고자 한다. 연구방법 : 2002년 8월부터 2005년 12월까지 천안시 소재 모대학교 재활의학과에 발달지연으로 내원한 아동 중 검사시 연령이 48개월까지의 아동 250명을 대상으로 Capute 발달검사인 언어지수(CLAMS), 인지적응검사(CAT), 혼합발달지수(CAT/CLAMS)와 Bayley 발달검사인 정신발달지수(MDI), 운동발달지수(PDI), 행동평가척도(BRS)를 검사하였고, 정신발달지수와 운동발달지수의 차이(MDI-PDI)를 계산하였다. 결과 : 1. 발달지연아 총 250명중에서 뇌성마비군이 86명(34.4%)으로 감별되었고 전반적 발달지연군은 164명(65.6%)이었다.2. 재태기간이 37주 미만군에서 뇌성마비아가 41.7%로 37주 이상군의 26.8%보다 유의하게 높았다(p<0.05).3. 뇌성마비군과 전반적 발달지연군에서의 Capute 및 Bayley 발달검사의 평균 점수의 차이는 Capute 발달검사인 인지적응검사지수와 혼합발달지수에서는 뇌성마비군에서 유의하게 낮은 점수를 보였으며(각각, p<0.001, p<0.01), Bayley 발달검사 중 운동발달지수와 행동평가척도도 뇌성마비군이 유의하게 낮은 점수였고(각각, p<0.001, p<0.01), 정신발달지수와 운동발달지수의 차이는 뇌성마비군이 유의하게 높은 점수를 나타냈다(p<0.001).4. Capute 발달검사의 각 지수별 뇌성마비 감별기준 점수로 80미만으로 하였을 때 인지적응검사지수, 혼합발달지수에서 뇌성마비군의 비율이 유의하게 높은 분포를 보였다(각각, p<0.001, p<0.01). Bayley 발달검사인 운동발달지수, 행동발달척도, 정신발달지수와 운동발달지수와의 차이의 감별기준 점수를 각각 85미만, 25미만, 13이상으로 하였을 때 뇌성마비군의 비율이 통계학적으로 유의하게 높은 분포를 나타내었다(각각, p<0.001, p<0.05, p<0.001).5. Capute 및 Bayley 발달검사의 각 지수 간에는 모두 유의한 상관관계를 나타내었다(각각, p<0.001).6. 뇌성마비 감별에 영향을 주는 예측 모형을 로지스틱 다중회귀분석 모형으로 분석한 결과 운동발달지수(Odds Ratio; OR=14.559, p<0.001)의 예측력이 가장 높았고, 다음으로 재태기간(OR=3.080, p<0.001), 정신발달지수와 운동발달지수의 차이(OR=2.678, p<0.01) 순으로 분석되었으며 이 모형의 설명력은 25.1%였다. 결론 : 발달지연 아동 중 뇌성마비아를 조기에 감별할 때에 Bayley 발달검사의 운동발달지수가 가장 유용한 것으로 나타났으며, 정신발달지수와 운동발달지수의 차이도 고려하는 것이 뇌성마비아 감별에 도움이 되는 것으로 나타났다.

        When tea trees were introduced to Korea peninsular from China? Historically, Mr. Taeryum, an envoy of Shilla dynasty brought tea seeds from China during Tang dynasty and the seeds were planted at Jiri Mt. by the order of King Heungduk at AD828. During Koryo Dynasty(918 1392), Buddhism spread rapidly all over the country and the tea culture reached its highest stage of prosperity. At the Chosun Dynasty, however, the ceremonial drinking of tea vanished almost completely due to the flourishing Confucian tradition, a kind of substitution of Buddhism. But a few people have supported the traditional tea culture by themselves. Since the independence of Korea soon after the World War II at 1945, Korean War have been exploded at 1950. After economic evolution have been succeeded at 1980, the cultivation area of tea trees has been increased about 2,000ha and the cultural tradition of tea drinking has become popular again at a tea consume quantities amounted to 100g per capita at 2004. The northern limited area of tea plant is lined on the southern part of Korea peninsular. It is very small region compared to China about one million ha and to Japan over 60 thousand ha. It is problem not only the area of tea fields but also the methodology of tea cultivation, for examples without clonal cultivars and mechanical systems. WTO treatments was discussing with Korea, China and Japan government at 2005. Green tea custom is very high at 514% in Korea. If three countries will be agreed the imported tax will be cut off, the Korean tea farmers will be confused because of unstable situation of tea markets. All most of tea farmers should be made the tea fields by seeding not clonal propagation. Because of clonal cultivars have not developed in Korea, there have not been the research institutes for tea plants and manufactures before 1992. Now there are three research institute of tea in Korea; Tea Experiment Station at Bosung of Jeonnam Agricultural Research & Extension Services, Mokpo Experimental Station of National Institute of Crop Science, and Green Tea Cluster Institute of Hadong. Mokpo and Hadong Research Station were established at 2004 and at 2005 but Bosung Station was established at 1992. Seven clonal tea cultivers were selected at Bosung Station; Bohyang, Myngsun, Chanlok, Sunhyang, Mihyang, Jinhyang and Ohsun until 2004. Mokpo Experimental Institute was started the tea provenance testing about 4 provenances: Kangwon-do, Jeonlabuk-do, Jeonlanam-do, and Kyungsangnam-do. Korean new tea cultivers should be selected because Koran wild tea population have been high genetic variation. If tea breeding research will be successful to select new clonal cultivers, the tea farmers of Korea will be stable after WTO treatment with each country.

        일반적으로 아스팔트 개질재의 경우 아스팔트 바인더의 고온 점성을 증가시킬 뿐만 아니라 믹싱 및 포설온도에서의 점도 또한 증가시켜 높은 생산온도 및 시공온도를 요구하게 된다. 이와 달리 Wax의 경우 아스팔트 바인더의 강성을 증가시키기도 하지만 일정 온도가 넘으면 물처럼 유동성을 확보해 믹싱 및 포설온도에서의 점도를 낮추어 작업성을 높이는 효과가 있다. 본 연구에서는 실내실험을 통해 PE Wax가 아스팔트 바인더에 첨가되었을 경우 그 특성을 분석하였다. 이를 위해 SBS, 폐타이어 고무분말 개질 아스팔트 바인더와 비교 분석하였다. 또한 Wax가 기존 개질재인 SBS, 폐타이어 고무분말과 함께 사용되었을 경우 그 효과를 분석하였다. 실험 결과, Wax type I은 내유동성 강화에 큰 효과가 있으며 작업성 개선에 약간의 효과가 있는 것으로 나타났다. Wax type II는 아스팔트 바인더의 작업성 개선에 크게 기여하고, 상온에서 부드러운 특성으로 균열에 대한 저항성을 증진시키는 것으로 나타났다.

        Hereditary dentin defects consist of dentin dysplasia(DD) and dentinogenesis imperfecta(DI). The DI associated with osteogenesis imperfecta has been classified as DI type I, whereas isolated inherited defects have been categorized as DI types II and III. However, whether DI type III should be considered a distinct phenotype or a variation of DI type II is debatable. Recent genetic findings have focused attention on the role of the dentin sialophosphoprotein(DSPP) gene in the etiology of inherited defects of tooth dentin. We have identified a novel mutation(c.727G → A, p.D243N) at the 243th codon of exon 4 of the DSPP gene in a Korean patient with DI type III. The radiographic and histologic features of the patient revealed the classic phenotype of shell teeth. These findings suggest that DI type II and III are not separate diseases but rather the phenotypic variation of a single disease.
