The aim of this study is to clarify the style of fashion design which represented three types of erotic mood. And it will have its significance in finding out some standards which call be applied to practical designing. The positive analysis on this study is composed of two parts-the analysis of fashion journals and of questionaire. Analysis of fashion design is to seize and to compare frequence of 17 style of fashion design in the delivery of erotic mood in $\ulcorner$Mot$\lrcorner$ and $\ulcorner$Vogue$\lrcorner$. The questionaire is to investigate preference and inclination of perception in erotic mood of 17 style of fashion design by sex and age. The results were as follows: 1) In $\ulcorner$Vogue$\lrcorner$ than in $\ulcorner$Mot$\lrcorner$ erotic style ate actively made use of. 2) To suggest style of fashion design expressed 3 moods of erotic can be applied to practical designing is as follows. Expression of 'romantic & mysterious' mood is desirab]e exposed body line in motion style in male, twenties and thirties. Expression of 'seductive h stimulating' mood is desirable bosom exposure, leg exposure, adhere of bosom, adhere of waist, seen-through leg, slit, exposed body line in motion style in male and twenties and seen-through bosom, adhere of hip, slash style in male. This mood is desirable exposed body line motion style in thirties and forties. Expression of 'sensuous & attractive' mood is desirable bosom exposure, leg exposure, adhere of bosom, adhere of waist, seen-through leg, slit, exposed body line in motion style in male and twenties and adhere of hip, seen-through bosom, slash style ill male. And this mood is desirable adhere of waist, arm exposure style in female and adhere of waist, exposed body line in motif style in thirties and forties.

Bisphenol A (BPA) is a monomer used in a polymerization reaction in the production of polycarbonate plastics. It has been used in many consumer products, including plastics, polyvinyl chloride, food packaging, dental sealants, and thermal receipts. However, there is little information available on the inhalation toxicity of BPA. Therefore, the aim of this study was to determine its inhalation toxicity and effects on the estrous cycle, spatial learning, and memory. Sprague-Dawley rats were exposed to 0, 10, 30, and $90mg/m^3$ BPA, 6 hr/day, 5 days/week for 8 weeks via whole-body inhalation. Mortality, clinical signs, body weight, hematology, serum chemistry, estrous cycle parameters, performance in the Morris water maze test, and organ weights, as well as gross and histopathological findings, were compared between the control and BPA exposure groups. Statistically significant changes were observed in serum chemistry and organ weights upon exposure to BPA. However, there was no BPA-related toxic effect on the body weight, food consumption, hematology, serum chemistry, organ weights, estrous cycle, performance in the Morris water maze test, or gross or histopathological lesions in any male or female rats in the BPA exposure groups. In conclusion, the results of this study suggested that the no observable adverse effect level (NOAEL) for BPA in rats is above $90mg/m^3$/6 hr/day, 5 days/week upon 8-week exposure. Furthermore, BPA did not affect the estrous cycle, spatial learning, or memory in rats.

The increasing use of mobile phones has raised public concern about the possible biological effects of radiofrequency electromagnetic field (RF-EMF) exposure on the human brain. To investigate the potential effect of RF-EMF exposure on the brain, we examined the behaviors and hippocampal morphology of C57BL/6 mice after sub-chronic exposure to RF-EMFs with a relatively high SAR level (5.0 W/kg). We applied a 2-hour daily exposure of WCDMA 1,950 MHz using a reverberation chamber that was designed for whole-body exposure for 60 days. In the behavioral tests, RF-EMF did not alter the physical activity or long-term memory of mice. Moreover, no alteration was found in the neuronal and glial cells in the hippocampus by RF-EMFs. In this study, we showed that sub-chronic whole body RF exposure did not produce memory impairment and hippocampal morphological alteration in C57BL/6 mice.

Our interest in human body is more and more increasing. Not only academic and art communities but also other social communities show a keen interest in the human body. Especially, the breast of women's body parts may be comparable to men's penis because it is protruded. The breast which sexually distinguishes women from men becomes an important topic in the fashion design community. Therefore, such designs which emphasize the breast are being introduced in a natural way. This paper aims at examining the reason and symbolism for the exposure of breast and analyzing the fashion design that breast is exposed. This study will help us grasp the meaning which the design has. The exposure's scope of breast in the design includes the partial exposure, total exposure and the concealment of breast. But these all have their effects in each scope. For this paper, some general things were investigated. They are as follows: the phases of breast exposure in the fashion design, the exposure of breast expressed in the works of fine art, and the alteration of breast-exposing phenomenon shown in apparels. Then, each type of breast-exposing design shown in the women's fashion was analyzed from the middle of 1980s' when the phenomenon of breast exposure occurred to the year 2004. These could be divided into 4 types. They include a suggestive type, an exaggerative type, an open type and a reproductive type. As the result of analysis of 4 types, such meanings of design as an emphasis of femininity, an expression of liberty, a symbol of maternity and a commercialization of sex could be analogized.

Purpose: Unlike the existing linear accelerator with photon, proton therapy produces a number of second radiation due to the kinds of nuclide including neutron that is produced from the interaction with matter, and more attention must be paid on the exposure level of radiation workers for this reason. Therefore, thermoluminescence dosimeter (TLD) that is being widely used to measure radiation was utilized to analyze the exposure level of the radiation workers and propose a basic data about the radiation exposure level during the proton therapy. Materials and Methods: The subjects were radiation workers who worked at the proton therapy center of National Cancer Center and TLD Badge was used to compare the measured data of exposure level. In order to check the dispersion of exposure dose on body parts from the second radiation coming out surrounding the beam line of proton, TLD (width and length: 3 mm each) was attached to on the body spots (lateral canthi, neck, nipples, umbilicus, back, wrists) and retained them for 8 working hours, and the average data was obtained after measuring them for 80 hours. Moreover, in order to look into the dispersion of spatial exposure in the treatment room, TLD was attached on the snout, PPS (Patient Positioning System), Pendant, block closet, DIPS (Digital Image Positioning System), Console, doors and measured its exposure dose level during the working hours per day. Results: As a result of measuring exposure level of TLD Badge of radiation workers, quarterly average was 0.174 mSv, yearly average was 0.543 mSv, and after measuring the exposure level of body spots, it showed that the highest exposed body spot was neck and the lowest exposed body spot was back (the middle point of a line connecting both scapula superior angles). Investigation into the spatial exposure according to the workers' movement revealed that the exposure level was highest near the snout and as the distance becomes distant, it went lower. Conclusion: Even a small amount of exposure will eventually increase cumulative dose and exposure dose on a specific body part can bring health risks if one works in a same location for a long period. Therefore, radiation workers must thoroughly manage exposure dose and try their best to minimize it according to ALARA (As Low As Reasonably Achievable) as the International Commission on Radiological Protection (ICRP) recommends.

Employees of nuclear medicine facilities performing medical procedures with the use of open radioactive sources require continuous detailed control of exposure to ionizing radiation. Thermoluminescent (TL) detectors placed in dosimeters: for the whole body, for lenses, ring and wrist dosimeters were used to assess exposure. The highest whole-body exposure of (1.70 ± 1.09) µSv/GBq was recorded in nurses administering radiopharmaceutical to patients. The highest exposure to lenses and fingers was recorded for employees of the quality control zone and it was (8.08 ± 2.84) µSv/GBq and a maximum of (1261.46 ± 338.93) µSv/GBq, respectively. Workers in the production zone received the highest doses on their hands, i.e. (175.67 ± 13.25) µSv/GBq. The measurements performed showed that the analyzed workers may be classified as exposure category A. Wrist dosimeters are not recommended for use in isotope laboratories due to underestimation of ionizing radiation doses. Appropriately selected shields, which significantly reduce the dose received by employees, must be used in isotope laboratories. Periodic measurements confirmed that the appropriate optimization of exposure reduces the radiation doses received by employees.

Objectives: The purpose of this study was to evaluate the personal exposure to $PM_{10}$ by body parts for the development of dust monitoring wearable device for swine farmers. Methods: Tasks were classified by using motion pictures taken by action cameras attached to swine farmers. Concentrations of $PM_{10}$ were measured by attaching direct-reading instruments at the head, neck and waist of worker. Differences of $PM_{10}$ exposure between body parts were analyzed with linear regression. Results: We identified three tasks(vaccination, moving pigs, and manure treatment). $PM_{10}$ concentration during vaccination was the highest among the tasks, and the body part showing the highest concentration of $PM_{10}$ was the waist regardless of task. In all tasks, the closer distance between the body parts, the higher were the R-squared values(vaccination 0.4221, moving pigs 0.6990, and manure treatment 0.2164). Conclusions: We presumed that $PM_{10}$ concentrations were affected by the parts of the body in which they were measured. In order to develop swine farmer's wearable device for monitoring dust concentration in air, the determination of the positions of monitoring sensor to ensure accurate measurement is essential. Considering the results of this study, wearable sensor should be positioned at the waist.

This paper addresses what amount of whole-body vibration is exposed to pilots of UH60 helicopters during flight. To measure the whole-body exposed from the feet and seat, the 12-axis vibration measurement system was used. It enables simultaneous measurement of vibration exposure from the body contact area of the feet, hip and back. The measured 12-axis vibration signals are exploited to the comfort level of UH60 helicopters during flight. It is shown that the evaluated ride value is close to $0.74{\sim}0.79m/s^2$ and that it is equivalent to the semantic scale of 'fairly uncomfortable'. To assess the health effects of whole-body vibration exposed to pilots of UH60 helicopters during their flight, the rms-based and VDV(vibration dose value)-based evaluation results of measured four-axis vibration signals are shown in this work. The fatigue-decreased proficiency limit, whose level is half of the exposure limit, is expected to come after the two-hour flight. The exposure limit is shown to reach after the 10-hour flight.

The purpose of this study is to investigate ideal body image and clothing style through the analysis of models portrayed in fragrance advertisement that is the representative goods showing the fashion brand image. For this study, 120 perfume advertisements appeared in GQ and Vogue magazines issued in 2002 were selected. The models' characteristics portrayed in advertisement are categorized with role relationship, race, body exposure and clothing styles. The results are as follows. 1. Fragrance advertisements most commonly depict a single model portraying narcissism, and later then most common are advertisements both male and female model in a sexual relationship. 2. The analysis of models' race shows racism toward Asian models and Afro- American models. White models are main characters in fragrance advertisements more often than other races, and in mixed-ethnic ads, whites typically outnumbered minorities. This shows currently aesthetic stereotypes, that is, white ideology still exists. 3. The results of models' body exposure are showing nudism with partially clad or nude. This shows the eroticism of male and female. 4. The highest portion of clothing style appeared in fragrance advertisement were casual wear for male model and dressy formal wear for female models, which respects current fashion trends.
