Hermaphroditism occurs rarely in human and animal populations. Previously, in Korea, The hermaphrodite dog in American Cocker Spaniel dogs have been reported in six cases. However, in this case, we found a hermaphrodite dog in Korean native Jindo dog. The characteristics were its enlarged os clitoris that was shown a reddish fingerlike structure protruding from the vulva. The dog was diagnosed as hermaphroditism with ovotestes. To our knowledge, this report is the first case of hermaphroditism in Korean native dog.

A method of instrumentally estimating the seismic intensity (MMI) based on Fourier Acceleration Spectrum, which is the so-called 'FAS MMI method' of Sokolov and Wald (2002), was considered for its applicability to Korea. In order to implement the FAS MMI method, the empirical models of mean (m) and standard deviation (${\sigma}$) for Korea were derived for MMI ${\leq}$ IV according to individual seismic intensity by using the site-consistent horizontal FAS of 580 records from 65 isoseismal maps prepared based on the reported MMI of Korea Meteorological Administration. The site-consistent FAS at a site were obtained by correcting the observed FAS for the difference of the site amplification function relative to that of the target site of Class D station (Yun and Suh, 2007) which was evaluated to be a representative site for the generic soil profile of Korea. The FAS m model for MMI ${\leq}$ IV follows the overall linear relation in log space according to seismic intensities, featuring the FAS mean model for MMI = IV similar to that of the global model of Sokolov and Wald (2002). The ${\sigma}$-values of the FAS model are found to be greater than those of the global model for MMI ${\geq}$ V, while significantly lower than those of the global model for MMI = IV.

A new species, Fimbristylis jindoensis J. Kim & M. Kim, is herein named and described. It is found on wet lowland mountain slopes in Jindo-gun, Jeollanam-do, Korea. Fimbristylis jindoensis shares several characteristics (long-creeping rhizomes, oblong spikelets, brown scales, and three-sided achenes) with the related species F. pierotii Miq. It is, however, distinct from F. pierotii, which has terete culms with five to six furrows that are 9-48 cm tall, flowers in June to July, a dry grassland habitat, fewer than ten spikelets, and simple anthela inflorescences. In contrast, the new species has shallow furrowed oval culms which are 57-93 cm tall, flowers in July to August, a wet mountain habitat, more than twenty spikelets, and compound anthela inflorescences.

In this paper, we present the evaluation results for the conservatism of the response acceleration method (RAM), for seismic response analysis of box-type power cable tunnels. We studied 50 examples, considering the cross sections of 25 power cable tunnels, and two soil conditions for each power cable tunnel. A refined dynamic analysis method considering the soil-structure interaction was further employed to evaluate the conservatism of the RAM. The comparison revelated that the seismic responses computed using the RAM were consistent with those obtained using the refined method, since the averages of response ratio (defined as the ratio of the response by RAM to that of the refined method) approached 1.0, and the standard deviations of the response ratio were less than 5%. Finally, we found that applying a load factor of 1.1 to the response of the RAM allowed for a conservative design for seismic loads.

This Research is focused on ancient battle formation basing on the layout drawing of Yijinchongbang (manuals of learning military formations) in a strategy book in the late Joseon dynasty. The research topic is the principles of organic composition of battle formation and battlefield operating system by reforming the basic model of ancient battle formation. The research method is comparative analysis by reforming the battlefield operating system of types of disposition such as Obangjindisposition(Bangnjin; battle formation, Jikjin; direct battle formation, Gokjin; bend battle formation, Wonjin; round battle formation, and Yejin; keen battle formation), and Hyunmoojindo; turtle battle formation, Paljindo; all-rounder battle formation, Yookhwajindo; six flowers battle formation, Gugunjindo; nine forms battle formation. From the study results, Standoff Bombing of the battle formation in the late Joseon Dynasty basically started out from magic battle formation, but was then transformed into square, rectangle, pentagon, and circle. Also, the battle array composition used a 5-linear structure and was composed of 5 systems of circulation such as rectangle, square, diagonal, curve, and circle. The research findings elucidate the battlefield of the Joseon dynasty by establishing the real battle formation, and thus have military and academic value in suggesting possible tactics that can be used by modern training of military.

In general, the seismic intensity deduced from instrumental data has been evaluated from the empirical relation between the intensity and the PGA. From the point of view that the degree of earthquake damage is more closely associated with the seismic intensity than with the observed PGA, JMA developed the instrumental seismic intensity (JMA instrumental intensity) meter that estimate the real-time seismic intensity from the observed strong motion data to obtain a more correct estimate of earthquake damage. The purpose of the present study is to propose a practical application of the JMA instrumental intensity in Korea. Since the occurrence of strong earthquakes is scarce in the Korean Peninsula, there is an insufficiency of strong motion data. As a result, strong motion data were synthesized by a stochastic procedure to satisfy the characteristics of a seismic source and crustal attenuation of the Peninsula. Six engineering ground motion parameters, including the JMA instrumental intensity, were determined from the synthesized strong motion data. The empirical relations between the ground motion parameters were then analyzed. Cluster analysis to classify the parameters into groups was also performed. The result showed that the JMA acceleration ($a_0$) could be classified into similar group with the spectrum intensity and the relatively distant group with the CAV (Cumulative Absolute Velocity). It is thought that the $a_0$ or JMA intensity can be used as an alternative criterion in the evaluation of seismic damage. On the other hand, attenuation relation equations for PGA and $a_0$ to be used in the prediction of seismic hazard were derived as functions of the moment magnitude and hypocentral distance.

The study on the classification of the Chindo Islands ascidians was conducted by collecting the specimens from five localities in July and November, 1994 and the previous records. The ascidians were classified into 7 families, 11 genera and 16 species. They are all known species in Korean waters. Among them nine species were found to be new to the Chindo Is. From the standpoint of water forms, the composition of the ascidians from Chindo Is. is made up of three elements, viz., temperate (8species, 50%), temperature-tropical (7 species, 44%) and tropical (1 species, 6%) . A boreal water species and boreal-temperature species were not found . It may be attributable to the fact that the water of this area is warm because of Kuroshio Water Current.

This study was conducted to analyze the genetic characteristics of the Jeju dog for preservation and protection. A total of 139 dogs from 7 dog breeds, including the Jeju dog, were genotyped using 16 microsatellite markers. The results revealed 2-18 alleles per locus, with a total of 131 alleles among the 16 markers. Most alleles were identified for FH3381, which had 18 alleles, whereas FH2834 had the fewest alleles, with just 2. When the total mean value was observed, the expected heterozygosity and observed heterozygosity were higher for than for outgroup dogs, and the PIC values ranged from 0.000 to 0.862, respectively. The phylogenetic tree analysis of the Jeju dog and other dog varieties revealed that the Jeju dog is closest to the Sapsal dog (0.393). The phylogeny between the Jeju and Korean domestic dogs showed that the Jeju dog is most distant from the Dongkyung dog (0.507). Looking at the distribution individually, the Jeju dog is in the same group as the Labrador Retriever and the Sapsal dog. Meanwhile, the Poongsan, Dongkyung, and Jindo dogs and the German Shepherd were in the same group. Genetic information confirmed through the results of this study can be used as basic data to study the genetic characteristics of the Jeju dog.
