  • We studied and compared the age structure, body size, and growth rates of field populations of two Korean salamander species (Hynobius yangi and Hynobius quelpaertensis) to elucidate important aspects of basic population dynamics of these two endemic Hynobius species. In both populations, females were sexually mature at three years of age, while H. yangi and H. quelpaertensis males matured at two and three years of age, respectively. Both males and females of H. yangi and H. quelpaertensis attained a maximum age of 11 years and 10 years, respectively. In both species, the snout-vent length (SVL) and body weight (BW) of the females were greater than those of the males. The SVL, BW, and asymptotic SVL of both male and female H. yangi were smaller than those of H. quelpaertensis. The adult growth rates after sexual maturation of male and female H. yangi were lower than those of H. quelpaertensis, possibly resulting in the smaller body size of the former, although overall growth coefficients were not significantly different between the two species. We also compared the age structure and growth rates of three Korean and three Japanese species of Hynobius.

  • To decide on the queuing system of the optimum-sized bank window, data by means of simulation was reckoned. That is, by linking the average arrival rate and the average service rate with the exponential random number, customers' arrival time and service time was reckoned and simulation size optionally decided. By so doing, this paper is aimed at predicting the conditions of a bank, average arrival time, average waiting time, aveerage service time, average queuing length, servers' idle time, etd, and at preparing for a simulation model of the queuing system that can apply not only to the bank window box but also to all system under which queuing phenomena may arise.

  • Banks play a crucial role in bringing stability and economic development through their expected contribution in proper financial resource mobilisation across the economy. Despite the importance, there is little focus in recent literature which provided the empirical evidence how the global financial crisis affect the bank efficiency in Bangladesh. Thus, this paper aims to examine the effect of the global financial crisis and other factors on the efficiency of Bangladesh commercial banks. By employing the Data Envelopment Analysis (DEA) method, we computed the technical efficiency of individual banks operating in the Bangladesh banking sector during 2000 to 2013. The empirical findings indicate that the Bangladesh banking sector has exhibited the highest efficiency level during 2001, while efficiency seems to be at the lowest level during 2010. The study finds that crisis along with bank size, capital adequacy ratio, return on average equity and real interest rate have a significant effect on bank efficiency in Bangladesh. In order to keep the sound financial development of Bangladesh, banks operating in the Bangladesh banking sector have to consider all the potential technologies which could improve their profit efficiency levels, since the main motive of banks is to maximise shareholders' value or wealth through profit maximisation.

  • The Comprehensive and Progressive Agreement for Trans-Pacific Partnership (CPTPP) is projected to provide several chances for Vietnam's banking industry to expand into the international market. This study examines the influence of foreign ownership on credit risk in Vietnamese commercial banks before the context of participation in the CPTPP. Using a sample of 28 commercial banks between 2009 and 2020, we find that foreign ownership has a negative relationship with bank credit risk. The regression methods used include the least-squares method, fixed-effects model, random effects model, and general least squares method. The research model adds interactive variables, which will help to reflect the role of intermediary factors more accurately such as listing on the stock market, capital ratio to the relationship between foreign ownership and bank credit risk. The test results reveal that increasing the foreign ownership ratio has a bigger impact on reducing credit risk for listed banks and banks with low capital than for other commercial banks. The government should flexibly adjust the foreign ownership ratio according to the capital size and role of each bank so that it can make good use of investment capital from abroad when Vietnam joins the CPTPP.

  • This paper examines the mainbank relationships of SMEs after the 1997 financial crisis in Incheon-Kyunggi and Daejeon-Chungnam regions where local banks have been merged by national banks. The results are as follows. First, national banks(except Industrial Bank of Korea and Kookmin bank) are reluctant to be mainbanks of regional SMEs. Second, those firms which have mainbank relationships with national banks borrow from relatively large number of banks. Third, their size measured by employees are relatively large. These tendencies become clearer after the 1997 financial crisis. It is the Industrial Bank of Korea and Kookmin bank that play important roles as mainbanks of regional SMEs. National banks including the Industrial Bank of Korea and Kookmin bank cannot be relationship lenders to SMEs due to the Williamson-type organizational diseconomies. It means that to ease the regional financial problems regional financial institutions are expected to play more active roles.

  • Aspidogastrid trematodes (Subclass Aspidogastrea) are a relatively small group with a characteristic adhesive disc and parasitize in a variety of cold-blooded hosts. Until now, only 2 species in the genus Cotylaspis, i.e., C. coreensis and C. sinensis, have been reported as the aspidogastrid trematode in the Republic of Korea (=Korea). In the present study, we intended to describe a species of aspidogastrids collected from the small intestine of the common carp, Cyprinus carpio, in a faunistic point of view. Total 51 specimens were collected from a carp caught in Nakdong-gang (River) on May 2015. Some of them were prepared as the specimens for light microscopic observations, and some others were prepared for SEM. They were slightly elongated without head lobes, $2,432{\times}840{\mu}m$ in average size, and had characteristic adhesive discs with 4 rows and 46 alveoli in average. The ovary was reniform and was located in the posterior-upper part of the body. The single testis was larger than the ovary and was located below the ovary. The uterus was coiled containing numerous eggs and distributed in the posterior 2/3 of the body. The vitellaria were follicular, and distributed from the mid-level of testis to near the posterior end. The morphological characters with dimensions of our specimens were closely identical with those of Aspidogaster ijimai previously described. A new aspidogastrid is added among the Korean trematode fauna by the present study.

  • Scale Invariant Feature Transform (SIFT) generates image features widely used to match objects in different images. Previous work on hardware-based SIFT implementation requires excessive internal memory and hardware logic [1]. In this paper, a new hardware organization is proposed to implement SIFT with less memory and hardware cost than the previous work. To this end, a parallel Gaussian filter bank is adopted to eliminate the buffers that store intermediate results because parallel operations allow all intermediate results available at the same time. Furthermore, the processing order is changed from the raster-scan order to the block-by-block order so that the line buffer size storing the source image is also reduced. These techniques trade the reduction of memory size with a slight increase of the execution time and external memory bandwidth. As a result, the memory size is reduced by 94.4%. The proposed hardware for SIFT implementation includes the Descriptor generation block, which is omitted in the previous work [1]. The addition of the hardwired descriptor generation improves the computation speed by about 30 times when compared with the previous work.

  • One of the most effective way to improve cache performance is to exploit both temporal and spatial locality given by any program executive characteristics. In this paper we present a high performance and low power cache structure with a bank selection mechanism that enhances exploitation of spatial and temporal locality. The proposed cache system consists of two parts, i.e., a main direct-mapped cache with a small block size and a fully associative buffer with a large block size as a multiple of the small block size. Especially, the main direct-mapped cache is constructed as two banks for low power consumption and stores a small block which is selected from fully associative buffer by the proposed bank selection algorithm. By using the bank selection algorithm and three state bits, We selectively extend the lifetime of those small blocks with high temporal locality by storing them in the main direct-mapped caches. This approach effectively reduces conflict misses and cache pollution at the same time. According to the simulation results, the average miss ratio, compared with the Victim and STAS caches with the same size, is improved by about 23% and 32% for Mibench applications respectively. The average memory access time is reduced by about 14% and 18% compared with the he victim and STAS caches respectively. It is also shown that energy consumption of the proposed cache is around 10% lower than other cache systems that we examine.

  • The present study was performed to compare the mitochondrial genomes between 2 Spirometra tapeworms, Spirometra erinaceieuropaei and Spirometra decipiens (Cestoidea: Diphyllobothriidae), which larval stages are important etiological agents of sparganosis in humans. For each species, the full mitochondrial genome was amplified in 8 overlapping fragments using total genomic DNA purified from a single worm as the template. The mitochondrial genomes were 13,643 bp (S. erinaceieuropaei) and 13,641 bp (S. decipiens) in length and contained 36 genes; 12 protein-coding genes, 2 ribosomal RNA (rRNA, small and large subunits), and 22 transfer RNAs (tRNAs). The 12 protein-coding genes constituted 10,083 bp (S. erinaceieuropaei) and 10,086 bp (S. decipiens) of their respective mitochondrial genomes. The tRNA genes, ranging in length from 56 to 70 bp, were identified based on putative secondary structures such as the typical cloverleaf shape. A total of 23 intergenic sequences, varying from 1 to 204 bp in size, were interspersed in S. erinaceieuropaei (total, 504 bp) and S. decipiens (total, 496 bp) mtDNA. The 12 protein-coding genes of S. erinaceieuropaei and S. decipiens differed by 12.4%, whereas the overall difference in mtDNA sequence between S. erinaceieuropaei and S. decipiens was 12.9%. Thus, from the standpoint of the mitochondrial genome, S. decipiens represents a valid species that can be distinguished from S. erinaceieuropaei.

  • This study disclosed the aqueous fruits extract of Rubus coreanus as a sustainable agent for the synthesis of Rubus coreanus zinc oxide nanoparticle (Rc-ZnO Nps) using as a reducing and capping precursor for co-precipitation method. The development of Rc-ZnO was assured by white precipitated powder and analyzed by spectroscopic and analytical instruments. The UV-visible (UV-Vis) studies indicate the maximum absorbance at 357nm which confirmed the formation of ZnO Nps and the purity, functional group and monodispersity were assured by field emission transmission electron microscopy (FE-TEM), Fourier Transform Infrared (FTIR) Spectroscopy and dynamic light scattering (DLS). The X-ray powder diffraction (XRD) data revealed the Nps is 23.16 nm in size, crystalline in nature and possess hexagonal wurtzite structure. The Rc-ZnO Nps were subjected for catalytic studies. The Malachite Green dye was degraded by Rc- ZnO NPs in both dark and light (100 W tungsten) conditions and it degraded about 90% at 4 hours observation in both cases. The biodegradable, low cost Rc-ZnO NPs can be a better weapon for waste water treatment.
