The present study purported to understand the relationships between SNS appearance-related photo activity, body image and self-esteem among young women. Objectification Theory and Social Comparison Theory explain the process how young women's SNS appearance-related photo activity influence their body satisfaction through a perceived media pressure, objectification of their own bodies and appearance comparison. These process ultimately affect the self-esteem of young female users. A research model was proposed and related hypothesis were examined. We collected an online questionnaire from 400 female participants in their 20's. Data were analyzed using SPSS 23.0 and AMOS 18.0. Structural equation modeling analyses suggested that the proposed research model provided a good fit to the data and supported most hypothesis. The results indicated that the level of SNS appearance-related photo activity significantly influences young female user's body satisfaction and self-esteem. The findings of this study were consistent with previous literature on media and body image. Limitations and future research suggestions were also described.

A carbon nanotube field emission display(CNT FED) panel with a 2 inch diagonal size was fabricated using a screen printing of a prepared photo-sensitive CNT paste and vacuum in-line sealing technology. After a surface treatment of the patterned CNT, only the carbon nanotube tips are uniformly exposed on the surface. The diameter of the exposed CNTs are usually about 20 nm. Using the photo-sensitive CNT paste, we have developed a triode type CNT FEA with a self-aligned gate-emitter structure. The turn on voltage was around 100 V which corresponds to according the turn on field of about $40V/{\mu}m$. By the creation of a self-aligned gate-emitter structure, it is expected that the screen printed photo-sensitive CNT paste is promising as a good candidate for the large size field emission display.

A self-charging supercapacitor is constructed through simple integration of the energy storage and photo exited materials at the photo electrode. The large band gap of $NiO/Fe_3O_4$ heterostructure generates photo electron at the photo electrode and store the charges through redox mechanism at the counter electrode. Sulfanilic acid azocromotrop/reduced graphene oxide layer at the photo electrode trapped the photo generated hole and store the charge by forming double layer. The solar supercapacitor device is charged within 400 s up to 0.5 V and exhibited a high specific capacitance of ~908 F/g against 1.5 A/g load. The solar illuminated supercapacitor shows a high energy and power density of 33.4 Wh/kg and 385 W/kg along with a very low relaxation time of ~15 ms ensuring the utility of the self charging device in the various field of energy storage and optoelectronic application.

This study aimed to investigate the relationship between oriented quality of life and fashion image with a focus on their futures. The results of this study are as follows. First, oriented quality of life was sampled as six factors such as information preference, job preference, self-preference, leisure preference, health preference, and self-defense preference, whereas an oriented fashion image was drawn as three factors such as urban image, individual image, and feminine image. Second, the self-defense preference had a significant effect on modern image and individual image as in Photo 1, while leisure preference and self-defense preference exerted a significant influence on feminine image in Photo 2. In Photo 3, leisure preference and self-defense preference affected urban image significantly, and health preference and self-defense preference respectively influenced individual image and feminine image. Third, as a result of investigating the difference between oriented quality of life and the sub-element of oriented fashion image according to the type of oriented quality of life, six groups of oriented quality of life (self-preference, job preference, self-defense preference, information preference, leisure preference, and health preference group) displayed significant differences only in individual image as presented in Photo 2. Fourth, in consequence of examining differences in the factor of an oriented fashion image according to the type oriented quality of life, six groups according to the type of oriented quality of life presented significant differences in the individual, splendor, elegant, refined, youthful, feminine, and modern image among the factor of oriented fashion image.

Background and objective: This study was conducted to examine the effects of the theme-based garden book (photo book) making integration program on social skills and self-determination of college students with developmental disabilities. Methods: We analyzed the changes in social skills and self-determination of college students with developmental disabilities. The first step was defining the theme-based garden book (photo book) making integration program, which was done by focus group interviews (FGI) comprised of specialists in the industry and academia. The second step was carrying out 8 sessions of the program. The third step was examining the effects of the program on social skills and self-determination of college students with developmental disabilities. The participants of this study were 36 college students with developmental disabilities attending N University, and 17 students were in the experiment group and the other 19 in the control group. Results: The control group showed no statistically significant changes in the three sub-domains of social skills, while the experimental group showed statistically significant differences across all three sub-domains, such as cooperation(P < .05), assertion(P < .05), and self-control(P < .05). The experimental group, that participated in the program showed statistically significant differences across all four sub-domains of self-determination skills, such as behavior (P < .05), cognition(P < .05), school support(P < .05) and home support(P < .05). This proved that the theme-based garden book (photo book) making program contributed to bringing positive effects to self-determination and social skills. Conclusion: These results suggest that the theme-based garden book (photo book) making integration program could improve self-determination and social skills of college students with developmental disabilities. These positive changes are related to the high level of interest in theme-based garden design programs among college students with developmental disabilities, and thus these programs can be used effectively to improve social adjustment.

A large leakage current may be one of the critical issues for poly-silicon thin film transistors(poly-Si TFTs) for LCD applications. In order to reduce the leakage current of poly-Si TFTs, several offset gated structures have been reported. However, those devices, where the offset length in the source region is not same as that in the drain region, exhibit the asymmetric electrical performances such as the threshold voltage shift and the variation of the subthreshold slope. The different offset length is caused by the additional mask step for the conventional offset structures. Also the self-aligned implantation may not be applicable due to the mis-alignment problem. In this paper, we propose a new fabrication method for poly-Si TFTs with a self-aligned offset gated structure by employing a photo resistor reflow process. Compared with the conventional poly-Si TFTs, the device is consist of two gate electrodes, of which one is the entitled main gate where the gate bias is employed and the other is the entitled subgate which is separate from both sides of the main gate. The poly-Si channel layer below the offset oxide is protected from the injected ion impurities for the source/drain implantation and acts as an offset region of the proposed device. The key feature of our new device is the offset lesion due to the offset oxide. Our experimental results show that the offset region, due to the photo resistor reflow process, has been successfully obtained in order to fabricate the offset gated poly-Si TFTs. The advantages of the proposed device are that the offset length in the source region is the same as that in the drain region because of the self-aligned implantation and the proposed device does not require any additional mask process step.

Present expression methods have close relations with popular culture in the active acceptance of various kinds of genre. Fashion illustration is no longer limited to sketching garments or technically explaining construction, it is accepted as an art that is expressed by the desire and consciousness of the artist. This study examines the expressional characteristics and effects of photo-image appropriation as an expression method in fashion illustration. The word 'appropriation' (to steal something) is used as euphemism and not meant to be derogatory. The methods of appropriation in art indicate that paintings are not inventions but are self-satisfactory creations that show that the idea of originality is false and that paintings should be uninhibited from the greed of the authority of the genius of artists. In postmodern paintings, the photo-image of appropriation are expressed through the methods of re-photography, photo collage, and photo painting. Photo-image appropriation methods in fashion illustration are re-photography, photo collage, image mixing of photography, drawing, and graphic expression of photography. Fashion illustrators are able to develop expression techniques for expanding a field of expression and enhance the ability of communication through the photo-image appropriation methods.

A $ZrO_2$ coating solution containing $ZrO_2$ photo-catalysis, which is transparent in visible light, was prepared by the hydrolysis of alkoxide, and thin films on the $SiO_2$ glass substrate were formed in a dipcoating method. These thin films were heat-treated at temperatures ranging from $250^{\circ}C-800^{\circ}C$ and their characteristics were subjected to thermal analysis, XRD, spectrometry, SEM, EDS, contact angle measurement, and AFM. Tetragonal $ZrO_2$ phase was found in the thin film heat treated at $450^{\circ}C$, and anatase $TiO_2$ phase was detected in the thin film heat-treated at $600^{\circ}C$ and above. The thickness of the films was approximately 300 nm, and the roughness was 0.66 nm. Thus, the film properties are excellent. The films are super hydrophilic with a contact angle of $4.0^{\circ}$; moreover, they have self-cleaning effect due to the photo catalytic property of anatase $TiO_2$.
