The artificial rains having different pH and weathering simulation test were performed for Gyeongju Namsan granite and dacitic tuff to predict the role of acid rain in the deterioration of stone monuments located in Gyeongju area. The pH 4.0 rain reacted with the fresh granite showed near neutral pH at the early stage due to the hydrolysis of minerals in the rock surface. But the pH changed back to the initial pH in the later stage. On the other hand, the pH 5.6 rain showed the neutral pH for a longer time than the experiment with pH 4.0 rain, reflecting slower reaction of minerals due to the weaker acidity. When the pH 5.6 rain reacted with the weathered granite, the water showed neutral pH longer than the case of the fresh granite. The similar tendencies were observed in the experiment of dacitic tuff, except that the pH 4.0 rain reacted with dacitic tuff took a longer time to go back to the initial pH as compared with the case of granite. These results may due to the differences in mineral composition and texture of two rocks. Dacitic tuff contains more fine-grained or glassy groundmass than granite and is more reactive with weaker acid rain. It was predicted that the weight loss and strength decrease rate of dacitic tuff would be approximatetly twice relative to those of granite in the same experimental environment.

The horse is relatively earlier domesticated animal species. Domesticated horses have been selected for their ability of racing, robustness, and disease-resistance. As a result, the thoroughbred horse genome has been condensed many genotypes related to exercise ability. In recent years, with the advent of NGS technologies, many studies were concentrated on finding superior genetic species in the horse genome in terms of genomics. Consequently, GWAS (Genome-wide Association study) is applied to horse genome, then genetic marker is revealed for superior racing ability. In addition, RNA-Seq is utilized as a method for analyze of whole transcript profiling in specific samples. By using this approach, specific gene expression patterns and transcript sequences can be revealed in various samples such as each individual, before and after exercise state, and each tissue. DNA methylation, a strong factor that regulate gene expression without the change of DNA sequence, have got a lot of attention. In horse genome, exercise- or individual-specific DNA methylation patterns were detected, and could be useful to develop selective marker of superior horses. MicroRNAs inhibit gene expression, and transposable elements accounted for half of the mammalian genome. These two elements are the crucial factors in functional genomics, and could be applied to the selection of superior horses. As the functional genomics and epigenomics advance, then these technologies introduced in this paper were applied to select superior horses. In this paper, the studies for selection of superior horses through genetic technologies, and development possibilities of these studies were discussed.

A nondestructive petrological investigation was carried out to identify the original location and form of the Gyeongju Seated Stone Buddha with Square Pedestals in the Blue House (so-called Stone Buddha in the Blue House). The Statue is a representative stone Buddha statue of Silla (9th century) but its original location is controversial and some parts were missing. Based on the petrological observation, magnetic susceptibility and gamma spectrometry, its stone material was identified as medium-grained alkali feldspar granite. This kind of granites are widely found in the Namsan, Gyeongju. It is very likely that the Namsan granites are the source of rock of the Stone Buddha. The Yudeoksa (Igeosaji temple site) and Namsan are possible to be the original home of the Buddha Statue since there are petrologically identical alkali feldspar granite outcrop distributed in Namsan and stone heritage made of the same stone type in both places. An investigation on the square middle stone base in the Chuncheon National Museum reveals that it is less likely to be the missing part of the Buddha statue as the stone base is fine- to medium-grained pink feldspar granite and has different magnetic susceptibility from the Buddha statue. This study confirmed the contribution and significance of petrological investigation to identification of stone heritage in Korea.

Within the Gyeongju Basin lies the central an ancient tombs (Wolseongbuk tombs), which are seen to be the core tombs of the Silla ruling class. An accurate understanding of the location of the ancient tombs, commonly known as a flatland area, provides a clue to understanding the contrast process and direction of the ancient tombs. This in turn requires an accurate understanding of the surrounding landscape, including where the ancient tombs are located. In other words, it must be possible to restore as much of the highland area as possible within the basin in which the ancient tombs are located. All data were analyzed as deeply as possible in order to identify the topographical features of the ancient tombs. As a result, it appears that the ancient tombs are located at the end of a fan or at the end of the line, and a large number of springs and wetlands are distributed around the area. This area is relatively low and unsuitable for generating high levels of moisture on the ground. These topographical features are directly related with the distribution of polymers, and solids were completely formed to avoid wetlands. Meanwhile, the ancient tombs are divided into several zones by springs and wetlands, and each area also has the characteristics of large groups where the boundaries are protruding and isolated. Also, this aspect was found to be true for the Oreung around Namcheon. After all, the location and distribution of Silla in the Daerungwon area are the result of the reflection of the fine geographical features of the Gyeongju basin, which are the key factors of springwater and wetlands.

This paper analyzes the characteristics of the ancient tombs discovered in the Gyeongju site and discusses the direction of the excavation. There are six special features of the wooden chamber tomb covered with stone in Gyeongju. First, confirmation of the above-ground type and the underground type burial mound. Second, confirmation of the construction such as the partition of mound and the pile of stone structure. Third, confirmation of the frontal part structure of the protect stone such as pebble-stone layer, boundary stone. Fourth, confirmation of the relationship before and after the mound. Fifth, the circumference and boundary of the confirmed(before 1990s) burial mounds were discovered, resolving the uncertainty. Sixth confirmation of the crowd unit tombs. By summing up these six features, it is possible to clearly divide the individual units and the crowd units of the Silla tombs. Confirmation of individual units and crowd units can clarify the size and scope of the tombs located by the concatenation and overlap. It is possible to get a glimpse of the formation process through the interrelationships between the two sides. The tombs are located in the upper-and-lower layer structure of the tombs and show selective site selection. When this formative process is rearranged, it is understood that the Gyeongju Silla Cemetery is formed through the course of four stages. It is anticipated that it will be possible to make selective projects in the excavation survey based on the confirmation of the individual unit and the crowd unit of the Silla ancient tombs and the formation process.

한반도 남동 해안은 중부 동해안의 정동진 지역과 더불어 많은 지형학자들에 의해 해안단구 지형발달에 대한 연구가 이루어져 왔다. 대보에서 방어진에 이르는 해안에서 해안단구는 크게 고위면, 중위면, 저위면으로 나누어지며, 이들은 다시 고위 I (H I)면, 고위II(H II), 중위면, 저위 I(L I)면, 저위II(L II)면으로 세분되었다. 특히 연구지역에서 북북동쪽으로 약 22km 떨어진 경주시 감포읍 대본리와 나아리에서는 고위면보다 더 높은 해발고도에서 고고위 I(HH I)면, 고고위II(HH II)면이 확인되었다(황상일ㆍ정혜경ㆍ윤순옥, 2000).

한반도 동해안 지역은 해안단구가 모식적으로 분포하여 이에 대한 연구가 활발하게 이루어 졌다. 1973년에 김서운에 의해 처음으로 한반도에 해안단구가 보고되었으나, 오랫동안 해안단구는 구정선고도 약 90m a.5.1.에서 형성된 것이 가장 높은 것으로 간주되었고 그 이상 고도에서는 확인되지 않았다. 이후 황상일 외(2000)는 경주 감포에서 110, 120, 130, 150m의 지형면이 존재할 가능성을 보고했으며, 강릉 정동진에서 윤순옥 외(2003)에 의해 고고위면이 110, 140m에서 확인되었다. (중략)
