전홍수 한국사진학회 2001 AURA Vol.8 No.1
I'd like to test the limit of photo. I made several pictorial experiments to test the border of photo and the boundary situation where photo identity reaches its limit. Also, I am interested in new expression techniques and in enlarging category to find ways out of the stereotyped idea and the existing framework of recording or artistic feature of photo. Specifically, I hate long been interested in the human body and the still life including flower. I try to create plastic beauty or new image by using multiple expressions, instead of focusing on the presence or the recording of photo. Whether it can be included in photo category or whether it will belong to another field isn't my concern. I take a look at the image of the object, but my work actually begins just at the point of time where it's judged by general photo concept that there are no more things to do. To generate subjective interpretation beyond the reality, the presence is deleted and the recording attribute is rooted out. The form is cut by an extreme form of framework, and nature is eliminated from color. Flower is so simplified that it's no longer accepted as flower, and the plasticity of the human body becomes a kinid of thing that it's no longer understood as the human body. I am charmed by the form or natural color of flower, but the unrealistic colors, which don't go through chemical mixture or light action and eventually never exist in the world yet prove nature best, also fascinate me. And I'd like to add brillianey arid mystery to color. I have no more interest in photo principle or text. Rather. I feel a queer delight in breaking various taboos, which should perhaps be observed by a photographer, in order to attain what's in my mind. Flower is like the genital organ of the human body. The close-up of flower seems to lead us into the world of sexual beauty and covert temptation that we feel from attractive people of the opposite gender. The plasticity of flower and human body makes me feel a scientific structural beauty, and gives a wonderful impression about the creation of a life.

The demand for LNG Carrier and LNG fuel ships are increasing due to global carbon neutrality declaration and ship emissions regulation of IMO, domestic shipyards pay technology fees(about 5~10% of ship price per vessel) to GTT company in France for making LNG cargo hold. Localization of LNG cargo hold is needed to reduce technology fees and engage technological competitiveness, it is important to secure the critical technology like automation process development of insulation system process. Especially, the automation rate of membrane-type insulation system is very low due to interference caused by corrugation and difficulty in securing optimal variable welding condition. In this study, to solve this problem, automatic welding is performed using developed automatic welding equipment on STS304L steel which is used in flat and corner area of membrane-type LNG cargo hold's lap joint. After welding, Cross-sectional observations and Tensile strength tests were conducted to evaluate reliability of equipment and welding condition. As a result of the test, it was confirmed that the strength of the welded zone exceeded that of base material, and secured the optimal welding condition to apply automatic welding.
