Ce travail est de rechercher la vie litteraire d'Eug?ne Ionesco ? l'?poque de la Roumanie(1921~1937). Ionesco fait partie d'une cat?gorie d'?crivains(Mircea Eliade, Emil Cioran, Tristan Tzara, Pana?t Istrati, etc) qui sont n?s en Roumanie et ont commenc? leur carri?re dans leur pays d'origine pour la continuer et l'achever en France. Eugen Ionescu devient Eug?ne Ionesco. Ce dernier repr?sente d?j? dans les ann?es 30 une personnalit? hors du commun. C'est un homme qui a deux patries, deux racines : une roumaine, une autre fran?aise. Sa vie est a ?t? marqu?e par ses publications des l'adolescence. Ils font l'objet de ce livre-portrait d'Eugen Ionescu, po?te et critique, ?crivain de langue roumaine. L'?tude de la jeunesse roumaine d'Ionesco nous m?ne sur un terrain p?rilleux, celui de la biographie, plus pr?cis?ment des ann?es d'adolescence, de jeunesse et d'apprentissage d'un ?crivain qui a masqu? cette p?riode de sa vie. Nous avons pr?fer? tracer une biographie intellectuelle plutot qu'?num?rer des d?tails anecdotiques. La projection d'Ionesco dans son oeuvre est le r?cit de ses propres aventures intellectuelles. Une part importante de notre travail est consacr?e ? l'anlayse d'un livre de critique Nu(Non) de jeune Ionesco. Nous avons utilis? le texte de la version fran?aise publi?e en 1986 pour ce travail. Pour Ionescu le Roumain, le po?te Ionesco, ?l?gies pour des ?tres minuscules, nous avons consult? une th?se d'Ecaterina Cleynen-Serghieve La jeunesse litt?raire d'Eug?ne Ionesco et puis l'?tude de Gelu Ionesco sur la carri?re roumaine d'Ionesco. Nous nous sommes aussi r?f?r?s ? divers documents comme Notes et contre-notes(1966), D?couvertes(1969), Journal en miettes et Pr?sent pass?, Pass? pr?sent(Mercure de France), et les entretiens avec Claude Bonnefoy pour comprendre la personnalit? d'un jeune ?crivain roumain.

Underwater photographing and image recording are essential for pre-excavation survey and during excavation in underwater archaeology. Unlike photographing on land, all underwater images suffer various quality degradations such as shape distortions, color shift, blur, low contrast, high noise levels and so on. Outcome is very often heavily photographing equipment and photographer dependent. Excavation schedule, weather conditions, and water conditions can put burdens on divers. Usable images are very limited compared to the efforts. In underwater archaeological study in very turbid water such as in the Yellow Sea (between mainland China and the Korean peninsula), underwater photographing is very challenging. In this study, off-site image distortion and color compensation techniques using an image processing/analysis software is investigated as an alternative image quality enhancement method. As sample images, photographs taken during the excavation of 800-year-old Taean Mado Shipwrecks in the Yellow Sea in 2008-2010 were mainly used. Significant enhancement in distortion and color compensation of archived images were obtained by simple post image processing using image processing/analysis software (PicMan) customized for given view ports, lenses and cameras with and without optical axis offsets. Post image processing is found to be very effective in distortion and color compensation of both recent and archived images from various photographing equipment models and configurations. Merits and demerit of in-situ, distortion and color compensated photographing with sophisticated equipment and conventional photographing equipment, which requires post image processing, are compared.

The distribution of seaweed was examined in Jeonnam archipelago marine ranching area, the coastal of geumo-do, Yosu. Abundance and distribution of seaweed in dropping site of artificial reef were sampled at 6 station at October 2007. Seaweed community were investigated with quadrat method at line-transect by scientific SCUBA divers. as a result, 30 species in total, 4 green, 9 brown and 15 red seaweed were identified. Range of seaweed biomass in all sampling stations were about 1,600~4,000 g/m². At intertidal zone, appearance of individuals and dominance rate were showed higher than below the subtidal line and at depth from 4m to 6m, individuals, dominance rate and biomass were represented low level. characteristic of water in marine ranching area is turbidity and also compensation depth is low. For that reason, individuals of seaweed community were smaller from depth of 4 meters. Therefore, when equip the artificial reef for preparation of seaweed beds need consider that equipment periods(early spring; before releasing marine seaweed spore) and suitable water depth(3~6m).

The purpose of this study was to explore how SCUBA diving instructors' perception on their divers affects the buddy selection process in SCUBA diving clubs. For the purpose of this study, 6 people who have more than 5 year experiences and have been working as instructor in scuba diving clubs were selected as research participants. The results are as follows. First, they perceived necessity of buddy selection through awareness of importance of buddy through education and through partner perception to overcome perceived danger. Second, when selecting a buddy, they established standards according to level whether they have a rescue diver license and secured standards through new sense of value. Third, buddy selection determinants were interaction between buddies, mutual trust and realization of buddy's role. As such, a SCUBA diver should select other buddy to perform pair diving and buddy is selected based on relationship such as mutual communication, mutual trust and belief. When they perform buddy's role comprehensively based on mutual relationship with buddy, continuous relationship as buddies can be built.

The importance of groundwater has long been recognized, but the ground water potential to become contaminated as a result of human activities has only been recognized in recently. Before 1980 it was thought that soils served as filters, preventing harmful substances deposited at the surface from migrating into groundwater. Today it is known that soils have a finite capacity to protect groundwater. It can be contaminated from divers sources. Therefore, Assessment of aquifer vulnerability to pollution is essential for the protection and management of groundwater and land use planning. In this study, we used DRASTIC and AVI for groundwater vulnerability to contamination assessment. the different methods were applied to the southern coastal sedimentary basin of Benin and DRASTIC method was modified in two different steps. First, we modified DRASTIC by adding land use parameter to include the actual pollution sources (DRASTIC_LcLu) and second, classic DRASTIC weights was modified using Shannon's entropy (Entropy weight DRASTIC). The reliability of the applied approaches was verified using nitrate (NO3^-) concentration and by comparing the overall vulnerability maps to the previous researches in the study area and in the world. The results from validation showed that the addition of landcover/land use parameter to the classic DRASTIC helps to improve the method for better definition of the vulnerable areas in the basin and also, the weight modification using entropy improved better the method because Entropy weight DRASTIC_LcLu showed the highest correlation with nitrate concentration in the study basin. In summary the weight modification using entropy approach reduced the uncertainty of the human subjectivity in assigning weights and ratings in the standard DRASTIC.

This study focused on novice drivers. Novice drivers get involved in more traffic accidents than the other drivers because of less driving experience. The aim of this study is to investigate the relationship between driving confidence levels and speeding, drunken driving, and traffic accidents. 192 drivers responded driving confidence levels questionnaire and driving experience items. 'Circumstance Insensibility', 'Unsafe Driving', 'Incautious Driving', and 'Self-efficacy of Driving' had significant relations with speeding in novice divers group. Especially, 'Circumstance Insensibility' showed a significant relation with speeding, drunken driving and traffic accidents. In the result of path analysis, driving confidence levels explained 22% of the speeding, 12% of the drunken driving and 21% of the traffic accidents in novice drivers group. 'Circumstance Insensibility' was most effective for traffic accidents of novice drivers. We verified that 'Self-efficacy of Driving' affects on traffic accidents via speeding.

Benthic marine invertebrates, the invertebrates living on the bottom of the ocean, are an essential component of the marine ecosystem, but excessive reproduction of invertebrate grazers or pirate creatures can cause damage to the coastal fishery ecosystem. In this study, we compared and evaluated You Only Look Once Version 7 (YOLOv7), the most widely used deep learning model for real-time object detection, and detection tansformer (DETR), a transformer-based model, using underwater images for benthic marine invertebratesin the coasts of South Korea. YOLOv7 showed a mean average precision at 0.5 (mAP@0.5) of 0.899, and DETR showed an mAP@0.5 of 0.862, which implies that YOLOv7 is more appropriate for object detection of various sizes. This is because YOLOv7 generates the bounding boxes at multiple scales that can help detect small objects. Both models had a processing speed of more than 30 frames persecond (FPS),so it is expected that real-time object detection from the images provided by divers and underwater drones will be possible. The proposed method can be used to prevent and restore damage to coastal fisheries ecosystems, such as rescuing invertebrate grazers and creating sea forests to prevent ocean desertification.

The span deflection among the monitoring items of bridge measurement system in real time is representative behaviour and important index of superstructure condition. the limit of span deflection in Standard Specifications for Highway Bridge in Korea has been applied to the method that is making the management-criteria for span deflection in bridge measurement system. But the limit concern mainly serviceability of divers. So it is difficult to find the safety factor of the limit from the viewpoint of bridge safety. This study estimated the safety factor of the limit of span-deflection in Standard Specifications for Highway Bridge in Korea from the viewpoint of bridge safety by the indoor structural test.

This study examined how to improve the Korean Navy diving system, particularly focused on using the mobile saturation diving system. This study determined the range of navy operations, and suggested requirements of mobile saturation diving system from the analysis of previous study and current Navy Diving system. Also, this study examined the use of military strategy in terms of its technical and applicable possibility for the enhancement of current system. In addition, the study analyzed both advantages/disadvantages of importing mobile saturation diving system products and domestic development. To review measures in installing and operating such system, this study included analysis on the effectiveness of individual platform. As the result, the study suggested requirements of mobile saturation diving system to be able to be operated by more than 6 divers for more than 17 days at more than 200m depth. And the study confirmed that there are beneficial to use mobile saturation diving system and current Navy saturation diving system together. However, it is low economical efficiency to change current Navy gas diving system to Saturation diving system. To review measures in installing and operating such system, this study suggested that second ATS-II should be built to be able to install mobile saturation diving system. Also, this study generated an utilization method of the system to use it for training when peacetime, and than it should be installed on other platform to use as additional salvage strength during wartime.

Weedy rice(red rice) collected in Korea were crossed with the Japonica, Javanica and Indica tester cultivars, and also crossed among those collected lines. Their seed fertility was counted and refered to their cross affinities. Some tester cultivars such as, Suweongjo, Malagkit Sinaguing and wx 817 which were regarded as belong to the Japonica, Javanica and Indica respectively, showed the typical tendencies of hybrid sterility when they were crossed each other. But, other testers such as Kwanak, Tapaiko, Belle Patna and Tarichaosun showed some differencies from those typical patterns, implying some varigations within a ecotype. The hybrids of weedy rice crossed to the Japonica testers showed higher fertility with a few semisterilities. While the crosses of weedy rice to the Javanicas or Indicas showed high sterility implying closer affinity relationships of weedy rice to the Japonicas. Even those weedy rice lines such as Samsanmyeon 8 and Sanchungaengmi B which showed semi-sterility when they were crossed to the Japonica testers showed high sterility when they were crossed to both Javanicas and Indicas. The hybrids among weedy rice lines showed high fertility raning 69% to 96%. Even those weedy rice lines which showed semi-sterility in the crosses with Japonica testers, showed high-fertility when they were crossed with those weedy rice lines. Though the amylose content, Alkali Digestive Value, Phenol reaction and grain shapes of theose weedy rice lines showed divers variations, the cross affinities of them showed closer phylogenie relationship to the Japonicas than to Japvanicas or Indicas. But the genetic influinces of Indicas to those weedy rices were not ignorable.
