소비자의 기성복 착용은 이미 보편화되어 있지만 일정한 치수체계에 맞추어 생산, 유통되는 기성복은 치수체계의 범위가 한정되어 있어 해당치수체계의 범위에 속하지 못한 소비자들은 자신에게 잘 맞는 치수의 기성복 구입에 어려움을 겪는다. 또한 20대 여성의 체형은 과거의 체형과는 많이 달라진 양상을 보이지만 국내 의류업체의 바지 치수규격은 여전히 한정된 치수만을 생산하고 있어 20대 여성의 체형에 적합한 바지의 생산범위에 한계가 있는 것으로 조사되고 있다. (중략)

FPSO(FSO)같은 대형 구조물을 육상에서 건조하여 LOAD-OUT 과 FLOAT-OFF 를 수행하기 위해 한 척의 반 잠수바지로는 불가능하였다. 그래서 두 척의 반 잠수 식 바지를 HINGED TYPE 이 아닌 FIXED TYEP 으로 연결하였고 이에 따라 FLOAT OFF 시에 고려하여야 할 사항 중에서 횡강도 및 바지가 잠수 할 시점의 STABILITY 가 중요시되었다. 또한 FSO 가 잠수바지로부터 떨어져 나올 시점에서, STABILITY CASING 과 FSO 와의 충돌가능성도 고려하여야 할 사항이다. 이 논문에서는 안정성 측면에서의 반 잠수식 바지의 BALLASTING과 충돌방지 차원에서 전체적인 OPERATION에 대하여 언급하였다.

Nobody has yet been able to determine the optimal solution conclusively whether NP-complete problems are in fact solvable in polynomial time. Gu$\acute{e}$ret et al. tries to obtain the optimal solution using linear programming with $O(m^4)$ time complexity for barge loading problem a kind of bin packing problem that is classified as nondeterministic polynomial time (NP)-complete problem. On the other hand, this paper suggests the loading rule of profit priority rank algorithm with O(m log m) time complexity. This paper decides the profit priority rank firstly. Then, we obtain the initial loading result using the rule of loading the good has profit priority order. Finally, we balance the loading and capability of barge swap the goods of unloading in previously loading in case of under loading. As a result of experiments, this algorithm reduces the $O(m^4)$ of linear programming to O(m log m) time complexity for NP-complete barge loading problem.

This study is on the spatial composition of accommodation area in accommodation barge. The accommodation barge which is used as living facilities for offshore plants' workers can be classified into Accommodation Work Barge, Accommodation Pipe Lay Barge and Multi-purpose Accommodation Barge. We study on the spatial composition of accommodation area in Accommodation Work Barge, most frequently used, through analyzing G.A drawings of the barges. The spatial composition has great influences into the convenience and amenity for workers' daily life in the accommodation area of accommodation barge. The spatial composition of accommodation area shows many characteristics not in horizontal arrangement on any deck but in vertical space arrangement on layers of decks. The particular types of vertical space composition can be classified into 'Centralized Type' and 'Dispersive Type'. These two types will be the basis of space planning for new accommodation barge.

When a barge is towed by a tug boat using a tow line, the barge is frequently subject to a large sway motion induced from its inherent yaw motions. This large sway motion combined with external forces due to winds and waves may makes the towing to be difficult or even dangerous. It has been reported that in worse situations, barges or tugs are capsized. In addition, the large sway motion of the towed barge gives a menace to the safety of ships navigating nearby. This paper is the results of the experimental investigation into the course stability of an 8,000 DWT barge using a Towing Tank and a Circulating Water Channel. Various skegs are designed and course stability tests for the barge with skegs are conducted in calm water and in irregular waves. It is observed that an effective skeg attached to the barge enables the sway motion to be zero while the sway amplitude of the bare hull is around 10 times its breadth.

In this paper, the towing force is calculated for the LNG bunker barge. LNG bunkering barge is being developed as an infrastructure for the bunkering of LNG(Liquefied Natural Gas), an eco-friendly energy source. In the case of the LNG bunker barge, a self-propulsion is considered through retrofit from an operating point. Therefore, the LNG bunker barge is similar to the shape of the ship as compared to a towed barge, so a rule of the towed barge overestimates the towing force. In order to improve accuracy, the calm water resistance is calculated according to the ITTC 1978 method considering the wave resistance by the Rankine source method. The added resistance in waves is calculated using the modified radiated energy method considering the shortwave correction method of NMRI. The performance of the towing resistances through the calm water resistance and the added resistance in waves was compared with rules of the towed barge.

In this paper, the towing stability of the LNG bunker barge was estimated. Currently, LNG bunkering barge is being developed for the bunkering of LNG (Liquefied Natural Gas), an eco-friendly energy source. Since the LNG bunkering barge assumes the form of a towed ship connected to the tow line, the towing stability of the LNG bunker barge is crucial f not only for the safety of the LNG bunker barge but also the neighboring sailing vessels. In the initial stages, a numerical code for towing simulation was developed to estimate the towing stability of the LNG bunkering barge. The MMG (Maneuvering Mathematical modeling Group) model was applied to the equations of motion while the empirical formula was applied to the maneuvering coefficients for use in the initial design stage. To validate the developed numerical code, it was compared with published calculation and model test results. Towing simulations were done based on the changing skeg area and the towing position of the LNG bunkering barge using the developed numerical codes. As a result, the suitability of the designed stern skeg area was confirmed.
