Distribution of Marine Debris collected from the Sandbar Coastline of Nakdong River Estuary after the Typhoons' Passage
Park, Son ; Yoon, Han-Sam ;
Journal of the Korean Society of Marine Environment & Safety, volume 13, issue 4, 2007, Pages 1~7
Using field observations, this study estimated the total weight and types of marine debris along the coast of Jinu Island in the Nakdong River Estuary after typhoons Usagi and Nari had passed. A numerical wave model was used to calculate the spatial wave height distribution at the time of the typhoons' passage. This study found that the total accumulation rate of marine debris deposited on the coast after the two typhoons had passed was about
at this site, which was 14.42 times as high as that in normal weather. The wave height distribution in the sea off Jinu Island, based on numerical modeling, was
, which was 1.0-2.5 times greater than for the case of other islands. Therefore, it is likely that the concentration of wave energy led to the deposition of marine debris.

Yoo, Chang-Ill ; Yoon, Han-Sam ; Kim, Gyou-Tae ;
Journal of the Korean Society of Marine Environment & Safety, volume 13, issue 4, 2007, Pages 9~14
This study reviewed the behavior(movement) characteristics of floating marine debris flowing in the Nakdong River Estuary using a simple numerical particle-tracking model on the conditions of the maximum water discharge outflow from the Nakdong River barrage during the passage of typhoon Maemi in 2003. The simulation showed that the particle distribution and movement of floating marine debris in the Nakdong River Estuary reached a stable state at 72 hours after the typhoon had passed, during the flood period of river discharge. The quantity of floating particles distributed on the east coast of Gadeok and Jinu Islands increased by 40% at 33 hours after starting the model, while the change in other sea areas was 20-40%.

Mass mortalities of the farmed sea squirt, Halocynthia roretzi, occurred in August, 2006 along the Gyeongbuk coasts of the East Sea without any pathological symptom. Suspecting the No. 10 typhoon, Wukong, which had passed over the relevant locations in the middle of August, 2006 as a culprit of the mortalities, we compared water temperature stratifications of the affected coasts before and after the typhoon. Just prior to the typhoon, cold waters lower than
were stratified at depths deeper than 10m probably by a persisting upwelling of cold bottom waters. The typhoon enforced water off-coast waters into coasts for 5 days, replacing the cold waters at depths
which can be justified by Ekman Spiral Effect. The results were an increment of water temperature by
and more at depths where sea squirts were suspended. The sudden elevation of water temperature might drive the sea squirts under abnormal stress to mass mortality.

Lee, Moon-Jin ; Kim, Hey-Jin ; Lee, Seung-Hyun ; Hang, Key-Yong ;
Journal of the Korean Society of Marine Environment & Safety, volume 13, issue 4, 2007, Pages 21~26
A study on analysis and application of ocean currents information extracted from SAR (Synthetic Aperture Radar) satellite image. The current information extracted from SAR satellite image is not real vector information but scalar information in normal direction of orbital path. To correct current information extracted from satellite image, observation of currents in the field is carried out at the same time and area as those of satellite image. In the analysis, current information extracted from satellite image is corrected by using observed ones. By this correction, the speed and the direction of current can be estimated. The extract current information seem to agree well with the observed ones.

Choi, Jong-Wook ; Lee, Seung-Hwan ;
Journal of the Korean Society of Marine Environment & Safety, volume 13, issue 4, 2007, Pages 37~42
Since the OPRC-HNS Protocol entered into forced in the June of 2007, the potential effects on industrial circles are encouraged to be analyzed according to the obligatory regulations listed in the Protocols. This study was conducted on the quantitative analysis of the possible effect on the industrial circles if Korea accedes to OPRC-HNS Protocol. In spite of any burdens caused by keeping "accident emergency program memorandum" and performing "education and any training program for the crews", potential decrease of insurance fee is in possibility provided it follows. In addition, the oil refinery and petrochemical industries may also have burdens for potential costs for acquiring any materials including equipments and fees for education and training related to HNS. However, minimizing any costs by swift response against accidents would be big advantage that comes with paying of small amounts of expense by international convention related to HNS.
A Study on the Recent Change in Korean Legislative System of Marine Environment Related Laws
Park, Su-Jin ;
Journal of the Korean Society of Marine Environment & Safety, volume 13, issue 4, 2007, Pages 43~50
Korea actively endeavors to improve the national marine environmental laws and regulations. Along with the growing global concern on the importance of marine environment, the concern is also increasing nationwide in Korea. These institutional changes in Korea have implications in that it has started to internalize the Sustainable Development Principle and the Precautionary Principle in the form of 'law' and 'policy.' The enactment efforts for conservation and sustainable use of marine environment will continue as the legal demand of public for coastal erosion prevention and climate change mitigation increases. This calls for robust revision for more logical framework and coherence of marine environment laws and regulations as well as efficient implementation of policies. In addition, it is strongly required that the systematical research and survey as well as the robust reversion of laws and policies should be taken accordingly for the effective conservation of marine environment.

Yim, Jeong-Bin ; Nam, Taek-Keun ;
Journal of the Korean Society of Marine Environment & Safety, volume 13, issue 4, 2007, Pages 55~63
The Group Digital Surveillance System for Fishery Safety and Security (GDSS-F2S) is to provide the target tracking information and the target identification information in order to secure an huge aquaculture farm-field from a thief. The two information, however, is not enough to indict the thief due to the lack of lawful evidences for the crime actions. To overcome this problem, we consider the target image information as one of solutions after discussion with the effective countermeasure tools for the crime actions with scenario-based analysis according to the geological feature of aquaculture farm-field. To capture the real-time image for the trespassing targets in the aquaculture farm-field area, we developed the image capture system which is consists of ultra sensitive CCD(Charge-Coupled Device) camera with 0.0001 Lux and supplementary devices. As results from the field tests for GDSS-F2S with image capture system, the high definite images of the vehicle number plate and shape, person's actions and features are obtainable not only day time but also very dark night without moon light. Thus it is cleary known that the improved GDSS-F2S with image capture system can provide much enough lawful evidences for the crime actions of targets.

Towing vessels have carried out the important role and service in the maritime industry construction, such as port and sea bridge construction, fairway dredging and sea reclamation etc. Furthermore, tugboat takes the largest portion in number of vessel at the domestic registry and barges as big as the general merchant vessel, which are getting specialized and larger, are in operation. In spite of the increase of marine accidents under this situation, there has been no proper measure for the safe navigation of tugboat in the aspect of a nation. This paper aims to propose the measure for the safe navigation of tugboat according to the frequent marine accident of tugboat with sea bridge. Therefore, we show an example of the sailing schedule and operation checklist based on the analysis of statistics and precedent of marine accident and the investigation of the actual operation state of tugboat in the aspect of a contract of carriage and a personnel setup, which should be checked by the operator of tugboat, to pass through sea bridge safely and propose the safe traffic supporting system based on electronic chart system to improve the safe navigation of tugboat.

Journal of the Korean Society of Marine Environment & Safety, volume 13, issue 4, 2007, Pages 79~85
Many countries foster the tour and leisure industries as a national strategic industry of the 21st century. The tour and leisure industry is expected to be reorganized from the land-based industry to the ocean-based industry as the GNP in a nation is over USD
dollars. In Korea, since we adopt a five-day week, the total working hours for a week is shortened. As the result, leisure activities in family, such as experience tour, ecological tour, travel, and overnight tour, are expected to be increased. Leisure and sports tours, which link the tour and sports to rafting, hang gliding, and marine leisure, have been also increased over 21.6%. A number of small and big islands near Ho-Nam coastal areas play an important role as natural breakwater. Thus, the ports in Ho-Nam area is safely protected from physical effects by ocean waves and is maintained without constructing a breakwater. In this paper, we analyses the required conditions as the marine leisure base in the southwest sea area which has the natural advantages for marine leisure. We also discuss how to activate the yacht business on Ho-Nam coast area. And then we analyse the present situations and obstacles of a domestic marine leisure. We also suggest the plan to build up echo-marine leisure infrastructure for industrial growth of marine leisure in Ho-Nam area.

Cui, Yun-Feng ; Yu, Yao-Dong ;
Journal of the Korean Society of Marine Environment & Safety, volume 13, issue 4, 2007, Pages 101~105
The people who lived in Fujian district along the south-eastern coast of China long ago began to construct ships and go fishing. For this reason, they grasped sound navigation skills and gained rich navigation experience. These skills and experience laid basis for the following large-scale overseas trade. In the Tang dynasty, with the development of economy, the people who lived in Fujian district started to leave home town and engage in overseas trade. In the Song dynasty and the Yuan dynasty, with the fast development of overseas communication, more and more Fujian maritime merchants, navigating the Fujian ships which were safe, fast and could arrive at destination on time, engaged in overseas trade. The Fujian ships made it possible for the Fujian maritime merchants to shorten trade time, catch business opportunity, level up the chance of success in trade and make full use of capital. As a result of this, Fujian maritime merchants gained fast development and they reached far areas such as eastern Asia, south-eastern Asia, southern Asia, and eastern Africa. This study deals with the issues such as the reasons for the development of Fujian maritime merchants, the trade engaged in by Fujian maritime merchants, the Fujian ships which played a decisive role in the overseas trade of Fujian maritime merchants.
A Study on the Evaluation of the Boarding Environment for the Ship Vibration (on the Basis of ISO-6954 : 2000(E))
Yu, Young-Hun ;
Journal of the Korean Society of Marine Environment & Safety, volume 13, issue 4, 2007, Pages 107~112
The vibration generated on shipboard is very important because it greatly affects on the comfortable mind of passenger and working conditions of crews. Shipboard vibration is closely concerned with the development of propulsion method and the type of main engine to decide speed of ship. To make the propulsion power, the main engine of ship have continuous explosion process in engine room, so the shipboard vibration is generated. The shipboard vibration causes the physiological and psychological damages to human body. In the case of the human body exposed to the shipboard vibration, the evaluation of human exposure to whole-body vibration is prescribed in ISO 6954 : 2000(E). In this paper, to evaluate the shipboard working environment, two kinds of vibration levels onboard ship were measured and compared with one another between engine rooms, engine control rooms and wheel house by the regulation of ISO 6954 : 2000(E).

The study was performed on the development of system in which the bead width can be controlled. In order to control the bead width, we designed the automatic seam tracking device by attaching the probe type strain gauge sensor, motor driving slide and encoder to check the moving distance, and interface card connected MCU(80Cl96KC) upside the speed controllable carriage. Seam tracking experiments were done by changing the bead width. We compared and analyzed the sampling data which were obtained by output voltage of strain gauge sensor and rotary encoder pulse every 50ms.
A Study of Built-Up Repair Welding for Stainless Steel Propulsion Shafting
Baik, Shin-Young ;
Journal of the Korean Society of Marine Environment & Safety, volume 13, issue 4, 2007, Pages 119~125
In recent days, the consumption of stainless steel in the propulsion shafting systems for small-medium class vessel is increased due to its high corrosion protection with wear resistant properties. Unfortunately the small and medium class vessel that operated in the west-south sea area of Korean peninsula experienced heavy wear down due to the role of mud. In the event of wear or broken down, the propeller shaft must be replaced by new one, but the new shaft is very expensive and time-consuming for order made supply. In this case, the methods of built up for wear and broken shaft by welding is one of the most effective cases. In this study, the built up welding for austenitic stainless steel shaft has been accomplished by various pre-surface treatment, welding methods, post heattreatment and inspection. The results confirmed that the built-up welding was one of the effective methods for stainless steel shafting.
