The mesh selectivity of hairtail (Trichiurus lepturus) caught by coastal drift gill net was examined in field experiments with three different mesh sizes (45, 50 and 55 mm) from October to November, 2013 in the coastal areas of south-west of Jeju province. The mesh selectivity tests were conducted with the experimental net to be set middle part of conventional driftnets. The mesh selectivity tests were carried out the total of four times. The selectivity curve was estimated by the Kitahara's and Fujimori's method. In the results, the catch number of hairtail was 653 (125.8 kg) and occupied 34.8% in total catches weight. The optimal mesh size for 50% selection on the minimum landing size (180 mm, AL) and the first maturity size (260 mm, AL) of hairtail were estimated as 47.2 mm and 64.5 mm by master selectivity curves, respectively.

MOF strengthen the law and institutions for safety management after the capsize accident of passenger ship "Sewol" on April 16, 2014. Nevertheless, about 13 cases of marine accidents such as collisions, contact, and stranding have occurred in coastal passenger ships over the past 5 years. Particularly, according to the judgment of KMST, most of the main causes of passenger ship accidents occurred within harbor areas because of the master's improper ship-handling or inattention. And so, this study analyzed four cases of marine accidents on passenger ships that occurred in the port areas and examined the environmental, institutional, material, and human factors that contributed to the master's improper ship-handling and behavior, and the results are as follows. First, as an environmental factor, the size of the turning basin was not enough. Second, as an institutional factor, the VTS control was not properly supported, the master lacked sufficient training for safe ship-handling in the port area and up-to-date charts were not provided. Third, as a material factor, the digital type speed log capable of the ship's speed in real-time was not installed on the ship's wing bridge. Lastly, as a human factor, the master could not take proper bridge resources and the passage plan was not proper. Therefore, it is suggested in this paper that the size of the turning basin should be adjusted to meet the prescribed standards, the master of passenger ships should receive the ship-handling simulation training among other safety training to ensure safe ship-handling of the master in the port area as improvement measures.

This paper presents the mesh selectivity of a net pot for common octopus Octopus minor for the sustainable resources management of common octopus. The filed experiments were carried out the total 10 times in the southern part of coastal sea in Korea from March to May in 2010 using net pots of five different mesh sizes (16, 18, 20, 22 and 26mm). The test of size selectivity, indicated a 50% selection value on the logistic master curve of 3.195, whereby 50% of individuals with a mantle size of approximately 70.3mm selected a mesh size of 22mm. Considering that 50% of common octopus entering sexual maturity have a mantle size of 70.6mm, the optimum mesh size should be equal to, or larger than 22mm.

"Stupa of Buddhist Monk, YeomGeo"(844) is known as the earliest Seon-stupa relic remains in Korean peninsula, from which, during late Silla and ealy Goryeo period, there were more than 30 of stupa was built on such canon. and became the well-known material culture in Seon Buddhism in late Silla period. In $9^{th}$ century, with the JeonDeong(delivering the light of Seon)from Tang to Silla, the culture of "GeonTapIpBi(building the pagoda and erecting stele)" was also moved in. And it was right after the style of monk's stupa had been methodically changed in china, from having the room in stupa for the corpse, named as "QuanShenSheLi", to the lessened stupa that contain the cremated. Analyzing the "Master ChengGuang's stupa"（807）and its stele, it can be found the correspondences of octagonal plan and the subjects of ornamentation to that of Stupas built in Silla, reveals they were made by the same canon. By the document in the stele, surmising the historical cause of alteration in Chan stupa, there was the most famous zen master ShenHui at the time, who has the most important role of making the NanZongChan to get the authenticity in Chan Buddhism. His reliqury was the first ${\acute{s}}ar{\bar{i}}ra$ casket discovered among Chan monks' relics, consequentially it was to influence to Chan cuture and size the monks 'stupa for his ${\acute{s}}ar{\bar{i}}ra$. The stupa of master ChengGuang, by its shape and geological location, is the lost piece in the Puzzle of Chan stupa culture between Silla and Tang.

Fishing experiments were carried out in the adjacent sea of Yeongil Bay, the eastern cost of Korea from 2003 to 2004 using the dome-shaped pots with different five mesh sizes (17.1, 24.8, 35.3, 39.8, and 48.3mm) in order to determine the size selectivity of pots for the whelk, Buccinum opisthoplectum. The catch species were composed of Buccinum opisthoplectum (45.4%), Buccinum striatissimum (30.1%), Pandalopsis japonica (9.3%), Chionoecetes opilio (8.9%), and so on. The shell height (l) of Buccinum opisthoplectum caught in the experimental fishing pots was measured. The SELECT (Share Each Length's Catch Total) analysis method was applied with fishing data to obtain master selection curve. The model with the estimated split parameter was found to fit the catch data best. The master selection curve was estimated to be s (R)〓exp (7.833R-10.871)/[1 + exp (7.833R-10.871], where R is the ratio of shell height to mesh size. The relative shell length for 50% retention was 1.388, and the selection range was 0.281. It means that the pots of larger mesh size allow more whelks of small size to escape.

When the PCI 2.2 bus master requests data using Memory Read command, the target device my hold PCI bus without data transfer for a long time because the target device requires time to prefetch data internally. Because the PCI bus usage efficiency and the data transfer efficiency are decreased due to this situation, the PCI specification recommends to use the Delayed Transaction mechanism to improve the performance. But the mechanism doesn't fully improve performance because the target device doesn't blow prefetch data size exactly. In this paper, we propose a new method to transfer data efficiently when the bus master reads data from the target device. The bus master informs the target device the exact read data size using prefetch request using Memory Write command. The simulation result shows that the proposed method has the higher data transfer efficiency than the Delayed Transaction about 10%.
