  • The purposes of this research were to find the general trends of sexual harassment at work and to investigate the differences of related variables. The data were obtained through 321 employee living in Kwangju. The major findings were as follows : 1) 53.0% of respondents reported that they had experienced the offence of sexual harassment at work at least once. And 57.9% of respondents reported that they had experienced the victimization of sexual harassment at work at least once. 2) The most apparent response of victimization at work was ‘anger’. And the most frequent coping behavior was ‘smiling or joking’. 3) The offence style of sexual harassment was different by sex, men's marriage, and sex-role attitude.

  • Media representations of race have attempted to contain blackness by packaging and commodifying it to reflect and affect preconceptions and prejudices of dominant culture. From the early beginnings of blackface minstrelsy as entertainment form in the $19^{th}$ century, representations of African Americans in popular culture and mainstream media have been closely associated with the notion of performance. The performative nature of racial representations is situated within the discursive struggle over what it meant to be Black, or what it meant to be labeled and portrayed as Black in American culture. This essay discusses four films that contain performances of "blackness" that assemble race and gender in complex configurations: Bamboozled (Spike Lee, 2000), Girl 6 (Spike Lee, 1996), Big Momma's House (Raja Gosnell, 2000), and White Chicks (Keenen Ivory Wayans, 2004). I explore how the performative nature of "blackness" is emphasized, thematized, and problematized in these films through the physicality of corporeal figures that embody the close link between race and gender identities. Once we are cognizant of the fact that race and gender are fabricated cultural constructs and performative acts, we can recognize that notions of "blackness" and "femininity" are not naturalized or essentialist, but open to recontextualization and revision.

  • The objective of this study was to evaluate the effect a chewable tablet containing sodium flouride and lauroyl sodium sulfate on removing plaque and inhibiting gingival inflammation. A randomized parallel study was designed. 100 voluteers participated in the study. There were two test groups each with 30 subject. Test group A was instructed to brush once in the morning, and to use the tablet once in the afternoon and once in the evening. Test group B was instructed to use the tablet three times a day without brushing. There were two control groups each with 20 subjects. Control group A was instructed to brush once in the morning only. Control group B was instructed not to brush all. Two weeks before the test period, the subjects received through tooth cleaning and polishing. At baseline, GI, PI, BOP, and GCF of the Ramfjord teeth were measured in all groups. Bacteria culture was done with the plaque sampled from tooth with the deepest pocket. After 5 days, clinical indices were measured and the bacterial culture was repeated. Control group B was dropped from the study after this period. All the other groups remained and the indices and the culture was repeated after 2 weeks, and 3weeks. Also whether the oral mucosa showed signs of irritation was monitored throughout the test period. Test group A showed less PI, GI, BOP, probing depth, GCF than test group B or control group A. Especially, PI and the BOP was significantly less than that of the group that was instructed to brush once a day. This implies that the added use of this tablet aids in plaque removal in people who brush just once a day. Test group A showed increase of cocci, decrease of motile rods, and decrease of spirochetes after 14-21 days. And this was significantly different from the control group A. At no time of the test period did any of the subjects show signs of irritation of the oral mucosa or adverse reactions. Following conclusions could be obtained from this study. This chewable tablet for enhanced oral hygiene could be used as an adjunct to oral hygiene in people who do not brush adequately. The use of this tablet decreased the number of subgingival bacteria, and this could be effective in plaque removal and for prevention of gingival inflammation.

  • In this paper, we implement an unmanned delivery robot system with Robot Operating System(ROS)-based mobile manipulator, and introduce the technologies employed for the system implementation. The robot consists of a mobile robot capable of autonomous navigation inside the building using an elevator and a Selective Compliance Assembly Robot Arm(SCARA)-Type manipulator equipped with a vacuum pump. The robot can determines the position and orientation for picking up a package through image segmentation and corner detection using the camera on the manipulator. The proposed system has a user interface implemented to check the delivery status and determine the real-time location of the robot through a web server linked to the application and ROS, and recognizes the shipment and address at the delivery station through You Only Look Once(YOLO) and Optical Character Recognition(OCR). The effectiveness of the system is validated through delivery experiments conducted within a 4-story building.

  • Though a variety of demands for an green dwelling, it is hard to diffuse a wooden house due to high construction cost. So this study aims to diffuse to propose a space modular for production and supply. Therefore the result of investigation to the space modular of each room through the survey of width and depth in the type of dwelling in korea is as follows. 1) Investigated the mixture of magnitude on the total width and depth, the survey is showed commonly 3.6m and 4.2m. 2) Once the depth is 3.6m, a living room and inner room, room's width is 3.9m, 4.5m. Once the depth is 4.2m, those width is 4.8m. 3) By use of a survey, the post distances consisted of all rooms are 3.6m, 3.9m, 4.2m, 4.5m, 4.8m. The result of investigation to possibility for mixture applied to six level types invested post modules to the wooden house of post & Beam method is as follows. 1) With the regularity of depth and simplicity of width, It is potential to compound floor plan in korea. 2) It is possible to plan an informal shape of kitchen+dining room which is a spare space available for the merit changeable space after arranged main rooms. 3) It is possible to plan a space through a variety of mixture method at bathroom. Thus, it is possible for a variety of floor formations to build a low-cost wooden house through five types of post distance.

  • A modified VIStA (Vortex Inertial Staged Air) burner has been developed and applied to a once-through type boiler. The secondary air is supplied through a swirler instead of nozzles, which stabilizes the flame and reduces carbon monoxide (CO) emissions. However, the modification increases the emission of nitrogen oxides (NOx). To balance emissions of the two pollutants, a divided flame was adopted. An air damper was installed to control the distribution of air to each combustion chamber, and three types of flame dividers were studied. The effects of the air-fuel ratio and combustion load on the NOx formation were investigated. The divided flame was found to reduce the NOx emission up to 25%, while keeping the CO to less than 10 ppm.

  • The increase of world's population and economic development are the keys drivers behind growing demand for energy. Especially the demand for electricity would eventually result in an increase of coal usage. Therefore ultra supercritical circulating fluidized bed boiler has been developed as solutions of economic eco-friendly technologies for coal and of increasing supplies of low grade fuels. Ultra supercritical circulating fluidized bed boiler has an once through type of steam cycle different from drum type in subcritical circulating fluidized bed boiler. Also, the duplication of a proven commercial module with 100-300 MWe subcritical circulating fluidized bed might be the key for design of 500~800 MWe ultra supercritical circulating fluidized bed boiler. After 2017, ultra supercritical circulating fluidized bed boiler might become standard model over subcritical circulating fluidized bed boiler. Therefore, this paper will help you to understand ultra super critical circulating fluidized bed (USC-CFB) through describing the background, status and prospect of the CFB technology.
