The purpose of this study was to analyze potential effects of Koreans' ultraviolet risk awareness and appearance management on their UV protective behaviors in daily life and outdoor activities, and was to investigate in their awareness of UV-protective clothing and their purchase attitudes toward anti-UV protective clothing. To meet the above goals, we have surveyed a total of 262 participants(male and female) residing in Chungcheong province. Findings were as following: As a part of ultraviolet-protective behaviors, it was found that the respondents often relied on applying sun-block cream or shady place before exposition to sunlight. Particularly, it was notable that 30's or older group was more proactive in UV protective behaviors than younger group below 30 years old. There were significant correlations among the respondents' UV protective behaviors, their awareness of anti-UV clothing and their purchase attitudes to anti-UV clothing. Also, there were also significant correlations among their UV-protective means for outdoor activities. That is, more favorable awareness about anti-UV clothing they have is associated with their more active attitudes to purchasing anti-UV clothing and taking anti-sunlight behaviors. It was found that the number of respondents who used cosmetics for outdoor activities was more than that of respondents who used clothing to protect their body from ultraviolet ray. Hence, it will be necessary for follow-up studies to focus on the development and promotion of anti-UV clothing.

The purpose of this study was to find factors affecting sun protective behavior and intention to buy UV-protective clothing among Korean golfers. Health belief (HB) model and diffusion theory(DT) were used for the study. Dependent variable of HB model was sun protective behaviors (SPBs) and dependent variable of DT model was intention to buy (ITB) UV-protective clothing. Independent variables for HB model were cancer perception, perceived benefits, behavioral/psychological barriers and cues to actions, while independent variables of DT model were relative advantage, compatibility, complexity, friability, and observability, besides demographic variables. Perceived benefits and cues to action variables in addition to gender and age were significant determinants of SPB for Korean golfers. Also, relative advantage and compatibility. behavioral barriers and cues to action were significant in affecting intention to buy UV-protective clothes. Both HB model and extended DT model were useful to predict sun protective behavior of Korean golfers.

As UV radiation to the earth increased over recent years, many adverse effects of UV radiation have been reported. There are needs to develop UV-protective apparel and accessaries to protect skin from these harmful effects. Cellulose is one of the most frequently worn fiber during summer time. However, celllulose shows very low UV-protective property especially in case of thin and low fabric content. In this study, UV-protective cellulose textiles were developed using chiotsan mordanting and green tea dyeing. The repetition effect of chitosan and green tea treatment were focused. Three different cellulose fibers, cotton, linen, and ramie, were used for this study. All chitosan mordanted and green tea dyed fabrics showed increases in UV-protective property. The color of fabrics tended to darker as the numbers of mordanting process and green tea dyeing increased. UV-protective property did not increase significantly upon the repetition of mordanting and green tea dyeing treatment except ramie fabric. UV protective property was persisted upon washfastness test in all three cellulose fiber types.

The objective of this study was to determine factors affecting sun protective behavior and intention to buy UV protective clothing among outdoor sport persons in Korea. A self-administered questionnaire was distributed to mountain climbers, bikers and in-line skaters with a convenience sampling method. Two theoretical frameworks, health belief(HB) model and diffusion theory(DT) were used for the study. Based on HB model, sun protection behaviors(SPBs) were associated with cancer perception, perceived benefits, behavioral barriers and cues to actions based on the HB model. Based on DT model, intention to buy (ITB) was determined by an individual's perceived attributes of UV protective shirt. Appearance concern variables were added to the extended HB model. The extended DT model was proposed by adding the variables in the HB model and variables of appearance concern. Multiple regression analysis was applied. Results were as follows. First, perceived benefits, behavioral barriers, cues to action, and all three appearance concern variables as well as gender and age were significant determinants of SPB for Korean outdoor consumers. Second, relative advantage, compatibility, friability, behavioral barriers and cues to action with some appearance concern variables were significant in affecting intention to buy UV protective clothes. Extended HB model and extended DT model were useful to understand SPBs of Korean outdoor consumers.

This research investigated the protective effect on hair for 3 commercial hair oil products containing UV filters upon UVA and UVB irradiation. Hair tresses each weighing 2 g were prepared from black virgin hair. Hair tresses treated with 0.5 g of hair oil were irradiated by UVA (365 nm) and UVB (302 nm) lamp for up to 600 hours. Color of hair was measured using a spectrocolorimeter, tensile strength and elongation of hair were measured using a biological tensile tester, surface morphology was examined using a scanning electron microscope. Experimental results were analyzed using SPSS statistical software. Hair color and tensile strength were both affected by UVA and UVB irradiation. Significant differences in the color and tensile strength were observed between untreated hair and hair treated with hair oils. Good UV protective effect observed in Oil 2 and Oil 3 was attributable to the type and the combination of UV filters contained in the products.

This study was designed to obtain the basic data developing the UV ray protective garments for the plastichouse workers. Two subjects were volunteered for 1hr. wear test in plastic house, and the ensembles was composed of one of three kinds blouse (UV blocking blouse, polyester/cotton 47/53 blouse, and polyester blouse), shorts, sleeveless undershirts, pants and socks. The measurements were rectal temperature, skin temperature, microclimate inside clothing, subjective sensation, and the colour difference of UV sensor. The results were as follows: 1. Microclimate especially, temperature inside clothing of polyester blouse was the highest among the garments. And UV-proof polyester blouse showed the lower mean skin temperature and microclimate than others. Showing the highest sweat volume. 2. No significant difference on UV ray blocking function among 3 kinds of garment was shown. 3. We could conform that in spring for the plastic house wぉw s garment low thermal insulating value and wide covering area were more important factors than UV blocking function of fabric.

This study examined the work environment and wearing conditions of industrial protective clothing in shipbuilding workshops. It also investigated the relationship between the wearing sensation of industrial protective clothing and overall comfort, according to work process. In addition, the work posture according to work process was evaluated based on ergonomic factors. The wearing rate of industrial protective clothing was 73.3%, 66.7%, and 60.1% for workers engaged in welding, grinding, and painting, respectively. The harmful work environment factors, listed from most harmful to least harmful, were found to be high temperature pyrogens, noxious fumes, organic solvents, UV rays, and heavy dust. The aspect of wearing performance of industrial protective clothing that was most related to user dissatisfaction was poor sweat absorbency. In terms of the correlation between the overall comfort and the wearing sensation of industrial protective clothing, the satisfaction was low shown in orders of physiological comfort, sensual comfort, and movement comfort.

This study investigates applying $TiO_2$ (titanium dioxide) nanoparticles to polypropylene nonwoven fabrics via electrospinning for the development of UV-protective materials. To fabricate uniform nanocomposite fibers, three types of $TiO_2$ nanoparticles were applied: powder, colloid, and $TiO_2$ coated polymer pellets. $TiO_2$/polyurethane (PU) and $TiO_2$/poly(vinyl alcohol) (PVA) nanocomposite fibers were electrospun and the morphology was examined using a field-emission scanning electron microscope and a transmission electron microscope. Layered fabric systems with electrospun $TiO_2$ nanocomposite fiber webs were developed at various concentrations of $TiO_2$ in a range of the web area density. The effects of $TiO_2$ concentration and web area density on UV-protective properties were examined. When $TiO_2$ colloid was added into a PVA polymer solution, uniform nanocomposite fiber webs in which $TiO_2$ particles were evenly dispersed were produced. Water-soluble PVA nanofiber webs were given a heat treatment to stabilize the electrospun PVA fibrous structure against dissolution in water. $TiO_2$/PVA nanoeomposite fiber webs with 2wt% $TiO_2$ and 3.0g/$m^2$ web area density exhibited an ultraviolet protection factor of greater than 50, indicating excellent UV protection.

Efficacy of Flos Sophorae as UV protective dye was examined in comparison to standard dyes of quercetin and rutin. Cotton was dyed using Flos Sophorae extract, quercetin, and rutin with 2 different concentrations for each dye. Each type of dyeing applied a temperature of 70℃ or 90℃ and a time of 30 min or 60 min. Color values of dyed samples were examined using a spectrocolorimeter. HPLC-DAD analysis indicated the amount of quercetin and rutin contained in Flos Sophorae used in the study. UPF values of dyed samples were measured using an ultraviolet transmittance analyzer. Experimental results indicated that dyeing cotton with Flos Sophorae extract, quercetin, or rutin increased the UPF value and decreased the UVA and UVB transmittance (%) regardless of dyeing conditions. A higher rank of UPF values were shown in cotton dyed using the Flos Sophorae extract that implied the possible concerted effect of quercetin, rutin, and flavonoid compounds contained in Flos Sophorae. The results indicated that Flos Sophorae is an effective natural dye that can improve the UV protective function of summer cotton fabric.
