Ostericum praeteritum $K_{ITAGAWA}(=Angelica\;koreana\;M_{AXIM}.)$ has been regarded as the original plant of Korean Qianghuo. The morphological and anatomical examination were made on Korean Qianghuo (crude drug fruits, purchased at markets and cultivated), and compared with Gangwhal $(O.\;praeteritum\;K_{ITAG}.)$. It was found that 3 species $A.\; polymorpha\;M_{AXIM}.,O.\;grosseserratum\;K_{ITAG}.,\;and\;O.\;sieboldi \;N_{AKAI}$. were different from Gangwhal. The original plant of Korean Qianghuo was identified as $A.\;polymorpha\;M_{AXIM}$, through this study.

In the original plant of Arisaematis Rhizomas, the features of external and internal shape of Arisaema amurense var. serratum $N_{AKAI}$ and A. amurense $_{MAXIM}$. are as follows. 1. In the external shape of original plant, Arisaema amurense var. serratum $N_{AKAI}$ has high stem, an oval-elliptic leaflet and a serrate leaf margin. But A. amurense $M_{AXIM}$ has a relatively low stem, an upside oval leaflet and no serrate leaf margin. 2. On the herbs character of original plant, Ansaema amurense var. serratum $N_{AKAI}$ is small in height and diameter, but A. amurense $M_{AXIM}$ is relatively large in height and diameter. 3. On the gathered herbs character of original plant, the section of Arisaema amurense var. serratum $N_{AKAI}$ is brightly white, easily spilt and strong scent. But the section of A. amurense $M_{AXIM}$ is thin yellowish brown, not easily spilt and weak scent. Also the grade of gathered herbs, both can be classified by diameter and external scent. 4. In the current herbs character, Korean and Sichuan Province products are irregullar shape and have no scent, Jilin Province products are regular shape. Also, Guangxi Province products are small size and concave in one side, Hebei Province products are irregular size and shape. 5. In internal shape of original plant, epidermal cell of Arisaema amurense var. serratum is very tight. With the except of micro difference in parenchyma cell of cortex, on the whole there are nearly no differences with A. amurense $M_{AXIM}$. Also, samely in the internal shape, according to collecting sites, epidermis exhibits a lot layer in curving state and secreting duct is developed and vascular bundle and exists between parenchyma cell of cortex. In the future, additional study is needed to distinguish herb and effect between same genus-degree of relatedness.

Objectives: Asari Herba comes from the dried perennial herbaceous plant, Asarum sieboldii $M_{IQ}$., A. heterotropides $F_R$. SCHMIDT var. mandshuricum($M_{AXIM}$) $K_{ITAG}$. and A sieboldii $M_{IQ}$ var. seoulense $N_{AKAI}$., family Aristolochiaceae. This medicine is pungent in flavor(味辛), warm in nature(性溫), mildly toxic and affects the lung, kidney, and heart meridians. It is able to repel wind dispel cold(祛風散寒), remove the obstruction of the nose(宣通鼻竅), relieve pain(止痛) and warm the lungs to remove the retention of fluids(溫肺化飮). In a clinic it is prescribed for exterior syndrome of wine-cold type(風寒表證) manifested as headache and general pain. It is indicated for headaches, toothaches, bisyndrome of wind-cold-dampness type(風寒濕痺), etc. For many generations medical books have warned doctors that the dosage of Asari Herba should not be excessive because the pungent flavor has the effect of dispersing exopathogens from superficies of the body. The principle, 'Asari Herba should not exceed Jeon(錢, Qian, 3.0 gram)' is still considered to be relevant. Methods : Extensive research of several ancient medical texts has lead to the following conclusion. Results : The statement 'Asari Herba should not exceed Jeon' is a dosage which is used to prepare single recipe and powder. Conclusion : The definition of Jeon is not 1 Jeon(3.0 gram), but 1 Jeonbi(錢匕, Qianbi, 1.0 gram), moreover, the usage, collection. and refinement process are not in accordance with the contents of the ancient medical texts. A deeper study of Asari Herba's dosage in the future is expected to have interesting results.

Poultry industry is abounding day by day as it engrosses less cost of investment per bird as compared to large animals. Poultry have the most copious genomic tool box amongst domestic animals for the detection of quantitative trait loci (QTL) and marker assisted selection (MAS). Use of multiple markers and least square techniques for mapping of QTL affecting quality and production traits in poultry is in vogue. Examples of genetic tests that are available to or used in industry programs are documented and classified into causative mutations (direct markers), linked markers in population-wide linkage disequilibrium (LD) with the QTL (LD markers), and linked markers in population wide equilibrium with the QTL (LE markers). Development of genome-wide SNP assays, role of 42 K, 60 K (Illumina) and 600 K (Affymetrix$^{(R)}$ Axim$^{(R)}$) SNP chip with next generation sequencing for identification of single nucleotide polymorphism (SNP) has been documented. Hybridization based, PCR based, DNA chip and sequencing based are the major segments of DNA markers which help in conducting of MAS in poultry. Economic index-marker assisted selection (EI-MAS) provides platform for simultaneous selection for production traits while giving due weightage to their marginal economic values by calculating predicted breeding value, using information on DNA markers which are normally associated with relevant QTL. Understanding of linkage equilibrium, linkage dis-equilibrium, relation between the markers and gene of interest are quite important for success of MAS. This kind of selection is the most useful tool in enhancing disease resistance by identifying candidate genes to improve the immune response. The application of marker assisted selection in selection procedures would help in improvement of economic traits in poultry.

잔교식 구조물은 선박을 안전하게 접안하여 화물을 송수신할 수 있는 구조물로서, 포화된 경사지반에 주로 설치된다. 이러한 잔교식 구조물의 내진설계 시 기준서에서는 예비 설계 방법으로 응답스펙트럼해석법을 활용하도록 제시하고 있으나, 현재 포화지반에 관입된 잔교식 구조물의 모델링 방법에 대한 지침은 부족한 실정이다. 그러므로 본 연구에서는 포화지반에 관입된 잔교식 구조물의 내진성능을 평가하기 위해 동적원심모형실험 및 응답스펙트럼해석을 수행하였다. 동적원심모형실험을 위해 잔교식 안벽 말뚝 중 일부 구간(3×3 군말뚝)을 선정하였으며, 지반 포화 여부에 따라 2가지 모델(건조, 포화)로 분류하였다. 이후 실험 모델에 지반 스프링 방법을 적용하여 응답스펙트럼해석을 수행하였다. 실험 및 해석을 비교한 결과, 건조지반 모델 및 액상화가 발생하지 않는 포화지반 모델의 경우 모멘트 차이가 최대 51% 이내로 발생하였으며, 깊이 별 모멘트를 적절히 모사하는 것으로 나타났다. 그러므로 본 모델의 경우 Terzaghi(1955)가 제시한 수평지반반력상수를 활용하여 모델링을 수행하는 것이 적절한 것으로 판단된다.

본 연구는 흙의 디지털 이미지로부터 획득된 토색을 기반으로 함수비를 예측하기 위한 기초단계로서 수행되었다. 서로 다른 다섯 가지 함수비로 조성된 주문진표준사 시료를 대상으로 광조건을 아홉 번 씩 바꿔가며 디지털 이미지를 촬영했다. 디지털 이미지 프로세싱을 통해 촬영된 시료의 토색을 CIELAB 색 표시계를 기반으로 획득하고, 광조건과 함수비에 따른 토색 변화를 분석했다. 그 결과, 불포화토의 토색 L^* 값은 조명의 조도와 높은 상관성을 보였고 a^*와 b^* 값은 조명의 색온도와 높은 상관성을 보였다. 또한 함수비가 증가하면 토색의 밝기를 나타내는 L^*가 감소하고, a^*와 b^*는 증가하여 토색이 초록과 파랑에서 멀어지고 빨강과 노랑에 가까워졌다. 광조건 및 함수비와 토색의 회귀분석 결과를 종합해 불규칙한 광조건에서 촬영된 실리카 계열의 모래의 토색을 기반으로 함수비를 예측하는 방법을 제안했으며, 제안된 방법을 통해 최대 오차 0.29% 수준으로 함수비를 예측할 수 있음을 확인했다.
