This study aims to review the article 26 of UCP 600. The article 26 of UCP 600 deals with 'on deck cargo' and 'unknown wording' in L/C transaction. The article 26 of UCP 600 says that a transport document stating that the goods may be carried on deck is accept able. UCP 600 requires to reject transport documents which evidence that the goods are or will be loaded on deck. So the bank will not accept the B/L containing a clause stating the goods are or will be loaded on deck. But in practice a container cargo is carried on deck actually but we do not describe this fact on the Bill of Lading. The deck stowage is not allowed under the clean B/L. But in case of container cargo, the carrier has the right to carry the container on deck in practice. In spite of this practice the carrier can not describe this fact correctly like this : "The container cargo loaded on deck". If carrier describes on B/L like this, the bank rejects the B/L in L/C transaction. So the carrier describes as "the goods may be carried on deck" on the back of the B/L. But they loaded the container on deck actually. This article suggests some ideas on this matter. In addition, the article 26 of UCP 600 says that a transport document bearing a clause such as "shipper's load count" or "said by shipper to contain" is acceptable. This means that a carrier has no responsibility on the contents of containers. In case of FCL Cargo, it is impossible for a carrier to check the details of container cargo. Therefore it is inevitable to insert the expressions such as "SLC(shipper's load and count)" or "STC(said to contain)". The wording described on the face of B/L should be interpreted as intended and consistently. The intention of the carrier is not the actual quantity or weight. So unknown wording does not represent the actual quantity or weight. But some cases show that the carriers are indemnified by such insertion but others reject the effectiveness of such insertion. So this study emphasizes that unknown wording can not fully indemnify the carriers and that the insertion of such expressions shall be minimized.

Terminal operators have provided special services such as loading, discharging, stowage of cargo to the owner, and carriers of the sea, which contribute the domestic and international logistics. For smooth flow of logistics, container terminal should reserve spaces for inbound and outbound logistics. However, if it is unable to provide the spaces, which can be caused by labour strikes or terminal lockouts and so on, national logistic system and financial management of terminal operators can be seriously affected. In order to minimize these kinds of problems, terminal operators impose high rate of charges ("overstorage charge") to the accumulated cargoes and/or containers, which are stipulated in terminal service agreement. Nevertheless, if there is no terminal service agreement with an owner of cargo and/or container, any kind of charge can cause legal problems (conflict ??) between the cargo and terminal operator. In this regard, I would like to study on the definition of overstorage charge and the legal issue of it based on the Busan district court's judgment. In particular, I will propose a special right of commercial lien and public auction for terminal operators to settle accumulated cargoes in container terminal.

The license plate recognition (LPR) unit consists of the following core components: plate region segmentation, individual character extraction, and character recognition. Out of the above three components, accuracy in the performance of plate region segmentation determines the overall recognition rate of the LPR unit. This paper proposes an algorithm for segmenting the license plate region on the front or rear of a vehicle in a fast and accurate manner. In the case of the proposed algorithm images are captured on the spot where unmanned monitoring of illegal parking and stowage is performed with a variety of roadway environments taken into account. As a means of enhancing the segmentation performance of the on-the-spot-captured images of license plate regions, the proposed algorithm uses a mathematical model for license plate colors to convert color images into digital data. In addition, this algorithm uses Gaussian smoothing and double threshold to eliminate image noises, one-pass boundary tracing to do region labeling, and MBR to determine license plate region candidates and extract individual characters from the determined license plate region candidates, thereby segmenting the license plate region on the front or rear of a vehicle through a verification process. This study contributed to addressing the inability of conventional techniques to segment the license plate region on the front or rear of a vehicle where the frame of the license plate is damaged, through processing images in a real-time manner, thereby allowing for the practical application of the proposed algorithm.

Objectives: To monitor the radon concentration level in plants that handle phosphorus rock and produce gypsum board and cement, and evaluate the effective dose considering the effect of radon exposure on the human body. Methods: Airborne radon concentrations were measured using alpha-track radon detectors (${\alpha}$-track, Rn-tech Co., Korea) and continuous monitors (Radon Sentinel 1030, Sun Nuclear Co., USA). Radon concentrations in the air were converted to radon doses using the following equation to evaluate the human effects due to radon. H (mSv/yr) = Radon gas concentration x Equilibrium factor x Occupancy factor x Dose conversion factor. The International Commission on Radiological Protection (ICRP) used $8nSv/(Bq{\cdot}hr/m^3)$ as the dose conversion factor in 2010, but raised it by a factor of four to $33nSv/(Bq{\cdot}hr/m^3)$ in 2017. Results: Radon concentrations and effective doses in fertilizer manufacturing process averaged $14.3(2.7)Bq/m^3$ ($2.0-551.3Bq/m^3$), 0.11-0.54 m㏜/yr depending on the advisory authority and recommendation year, respectively. Radon concentrations in the gypsum-board manufacturing process averaged $14.9Bq/m^3$ at material storage, $11.4Bq/m^3$ at burnability, $8.1Bq/m^3$ at mixing, $10.0Bq/m^3$ at forming, $8.9Bq/m^3$ at drying, $14.7Bq/m^3$ at cutting, and $10.5Bq/m^3$ at shipment. It was low because it did not use phosphate gypsum. Radon concentrations and effective doses in the cement manufacturing process were $23.2Bq/m^3$ in the stowage area, $20.2Bq/m^3$ in the hopper, $16.8Bq/m^3$ in the feeder and $11.9Bq/m^3$ in the cement mill, marking 0.12-0.63 m㏜/yr, respectively. Conclusions: Workers handling phosphorous gypsum directly or indirectly can be assessed as exposed to an annual average radon dose of 0.16 to 2.04 mSv or 0.010 to 0.102 WLM (Working Level Month).

This study discusses data collection, calculation of wind and wave-induced resistance, and speed-power analysis of an 8,600 TEU container ship. Data acquisition system of the ship operator was improved to obtain the data necessary for the analysis, which was accomplished using SPA (Ship Performance Analysis, Park et al., 2019) in conformation with ISO15016:2015. From a previous operation profile of the container, the standard operating conditions of mean draft were 12.5 m and 13.6 m, which were defined with the mean stowage configuration of each condition. Model tests, including the load-variation test, were conducted to validate new ship performance and for the speed-power analysis. The major part of the added resistance of container ship is due to the wind. To check the reliability of wind-resistance calculation results, the resistance coefficients, added resistance, and speed-power analysis results using the Fujiwara regression formula (ISO15016:2015) and Computational fluid dynamics (Ryu et al., 2016; Jeon et al., 2017) analysis were compared. Wind speed and direction measured using an anemometer were used for wind-resistance calculation and the wave resistance was calculated using the wave-height and direction-data from weather information. Also, measured water temperature was used to calculate the increase in resistance owing to the deviation in water density. As a result, the SPA analysis using measured data and weather information was proved to be valid and able to identify the ship's resistance propulsion performance. Even with little difference in the air-resistance coefficient value, both methods provide sufficient accuracy for speed-power analysis. The differences were unnoticeable when the speed-power analysis results using each method were compared. Also, speed-power analysis results of the 8,600 TEU container ship in two draft conditions show acceptable trends when compared with the model test results and are also able to show power increase owing to hull fouling and aging. Thus, results of speed-power analysis of the existing 8,600 TEU container ship using the SPA program appropriately exhibit the characteristics of speed-power performance in deal conditions.
