Atomic layer epitaxy is a relatively new epitaxial pprocess chracterized by the alternate and separate exposure of a susbstrate surface to the reactants contaning the constituent element of a compound semicoductror. The ideal ALE is expected to provide sevral advantageous as petcts for growing complicated heterostrutures such as relativly easy controls of the layer thinkness down to a monolayer and in forming abrupt heterointerfaces though monolayer self-saturatio of the growth. In addition, since ALE is stongly dependent on the surface reaction, the growth can also be controlled by photo-excitation which provides activation can be energies for each step of the reaction paths. The local growth acceleration by photo-excitation can be exploited for growing several device strures on the same wafer, which provides another important practical advantage. The ALE growth of GaAs has advanced to the point the laser opertion has been achieved from AlGs/GaAs quantun well structures where thee active layers were grown by thermal and Ar-laser assisted ALE. The status of the ALE growth of GaAs and other III-V compounds will be reviewed with respect to the growth saturation behavior and the electrical properties of the grown crystals.

We report a low-temperature fabrication of organic/inorganic nanohybrid dielectrics for organic thin film transistors. The self-assembled organic layers (SAOLs) were grown by repeated sequential adsorptions of C=C-terminated alkylsilane and metal (Al or Ti) hydroxyl with ozone activation, which was called "molecular layer deposition (MLD)". The $TiO_2$ and $Al_2O_3$ inorganic layers were grown by ALD, which relies on sequential saturated surface reactions resulting in the formation of a monolayer in each sequence and is a potentially powerful method for preparing high quality multicomponent superlattices. The MLD method combined with ALD (MLD-ALD) was applied to fabricate SAOLs-$Al_2O_3$-SAOLs-$TiO_2$ nanohybrid superlattices on polymer substrates at relatively low temperature. The MLD method is an ideal fabrication technique for various flexible electronic devices.

Cranioplasty is an in evitable operation conducted after decompressive craniectomy (DC). The primary goals of cranioplasty after DC are to protect the brain, achieve a natural appearance and prevent sinking skin flap syndrome (or syndrome of the trephined). Furthermore, restoring patients' functional outcome and supplementing external defects helps patients improve their self-esteem. Although early cranioplasty is preferred in recent year, optimal timing for cranioplasty remains a controversial topic. Autologous bone flaps are the most ideal substitute for cranioplasty. Complications associated with cranioplasty are also variable, however, post-surgical infection is most common. Many new materials and techniques for cranioplasty are introduced. Cost-benefit analysis of these new materials and techniques can result in different outcomes from different healthcare systems.

Statement of problems. Conventional feldspathic porcelain is used extensively as a restorative material and it is subjected to grinding and polishing during fabrication and delivery procedures. There is still considerable controversy concerning the best methods to achieve the strongest porcelain restorations after such adjustments. Purpose. The objective of this study was to investigate the effects of (1) overglazing, (2) selfglazing, and (3) fine polishing on the flexural strength and fracture toughness of feldspathic dental porcelain. Material and method. Ninety porcelain disks were prepared for flexural strength test and sixty porcelain disks were fabricated for fracture toughness test. Specimens were divided into three groups for each test as follows: 1) overglazed 2) self-glazed 3) polished. The flexural strength of feldspathic porcelains was determined by ring-on-ring biaxial flexural strength test. The fracture toughness values of three experimental groups were obtained by indentation fracture toughness test. Results. The flexural strength of overglazed group was significantly higher than that of selfglazed and polished group (P<0.05), while the difference between self-glazed and polished group was not significant (P>0.05). The fracture toughness values of overglazed and polished group were significantly higher than that of self-glazed group (P<0.05), while the difference between overglazed and polished group was not significant (P>0.05). Conclusions. This results supported the use of polishing as an alternative to glazing metal ceramic restorations, as it was not detrimental in flexural strength and fracture toughness. But, under the conditions of this study, overglazing was the ideal surface finishing method of feldspathic dental porcelain.

In the $21^{st}$ century, technology is a tool for the expansion of the five senses and physical ability that works as an element for posthuman identity. This study analyzes and theorizes on the characteristics of the posthuman body in fashion illustration. The method of this study analyzes documentaries about posthuman and fashion illustration. The results are as follow. Posthuman body types are classed as hybrid body, plastic surgery body, and digital body. The characteristics of the posthuman body are categorized as ultra- functional prosthetic, mythical undifferentiated, radical plastic surgery type and post-physical digitization type. The ultra-functional prosthetic type shows a restored body and upgraded functional body through a machine hybrid, cyborg suit and mannequin hybrid. It is a break from classical gender identity to form a nerve sense extension that displays physical and abstract power. The mythical undifferentiated type shows a therianthropic form, parts of an animal body, radical skin and gender bending. It represents the return to an undifferentiated world, the desire of a powerful being and the possibility of radical transformation. The radical plastic surgery type shows a photomontage of an ideal body, transgendered body, grotesque body marking, absence of partial or overall face organ and the expansion of abnormal body organs. It represents the expression of narcissism, unconscious desire, fantasy, fear and suggests an alternative ideality, sexual attachment and ambiguous gender identity. The post-physical digitization type shows an imperfect form or duplicated ego image through the omission of the body silhouette or detailed form, fragmented image using net, representative self like optical illusion using typography, an imperfect vague silhouette and immaterial body outline through the use of virtual light. It represents the lack of desire, narcissism, fluidity in a virtual space, the continued creation of a new self, ambiguous gender identity and the liberation of environment, sex, and race. Likewise, the posthuman in fashion illustration shows the absence of a species boundary, destruction of classical gender identity, a new personality and virtual self image.

In order to investigate female workers' recognition of image making, this study conducted a survey of female workers in Daegu and obtained results as follows. First, according to the result of analyzing recognition of image making, many of female workers, 82.3% of whom were between 20s and 40s, replied that they were 'pure and lively'(41.8%) or 'elegant and womanly'(32.3%) but what they sought for in their mind was an elegant and womanly image. However, the image that a majority of female workers wanted to have in the future was 'elegant and womanly' (53.3%) and 'sexy and attractive'(27.4%). This suggests that our society still demand women to be womanly as well as sexy and attractive. Second, with regard to outward image by age, most female workers regardless of age thought that outward image is important for social life. This suggests that younger women recognize more the influence of image and, consequently, the necessity of image making. Thus, the recognition of the importance of outward image appears to result in the proportional enhancement of the consciousness of image management. Third, younger women have a great difference between their current image and the image they seek for and such a difference may be related to mental immaturity between ideal and reality. Fourth, as for the relationship between image making and occupation, those who engaged in service and beauty art highly recognized the importance of image making as they were greatly influenced by their outward image in their social life.

The purpose of this study is to analyze the various signs seen on TV commercials for school uniforms since year 2000, thus uncovering the connotative meanings in them. For this study, the semiotic approach has been used. The signs seen on the TV commercials are separated into linguistic and visual signs. They are found to have symbolic connotations. The results are as follows: First, there are plenty of signs expressing the sense of belonging to the student group and sense of conformity to his or her peer group. They are intended to garner their collective identity in the peer group of teenagers. Second, the TV commercials express the self that is realizing one's value dynamically. The frequent designation of 'I', 'me' and 'myself' represents that I am at the center of the world. Furthermore, the suggestion of diverse student roles beyond mere academic pursuits symbolically shows the ideal self that most teenagers wish to have. Third, the TV commercials implied a commercial ideology. That is expressed in the emphasis on aesthetic value that teenagers can realize their self only by consuming expensive school uniform brands. Forth, there are many signs related to appearance and appearance care. They are expressed with very specific signs such as 3 : 7 proportion, long legs, small face, and so on. Repeating or emphasizing the importance of looks and a certain brand name as the tool to accomplish better looks indicates that it contains the ideology of appearance management.

This study analyzed the consciousness, unconsciousness, and individuation process of 'Cheongmyeong', the protagonist presented in the webtoon "Return of the Blossoming Blade", based on Jung's theory of individuation. The subject of the research was the webtoon "Return of the Blossoming Blade", which has formed a readership across various genders and age groups, based on a successful web novel. The individuation process of the protagonist of "Return of the Blossoming Blade", analyzed using Jung's theory, is as follows: Firstly, the protagonist's ego originated from the shadow derived from the unconscious. Secondly, the protagonist's persona is social and positive in reality, but the personal persona manifested as an unrevealed shadow. Thirdly, the protagonist's anima/animus connects the profound inner consciousness with reality, maintaining a complementary relationship with the persona. Fourthly, the protagonist's Self symbolizes the collective ideal human and the essence of the volcano. The protagonist was shown to achieve individuation through a continuous repetitive process of integrating consciousness and unconsciousness, and through the compensatory process.

The purpose of this study was to provide information on obesity assessment for Koreans. Among total of 1012 research papers enlisted in the Korean J Community Nutrition form 1996 to 2011, 248 articles were examined in which subjects were divided into more than 2 groups by obesity rate. About the method of anthropometric data collection, more than half of the research papers examined 52.5% and 28.7% of studies utilized the directly measured data and self-described data, respectively. About the utilization of obesity assessment methods, indirect methods of weight-height index (BMI, BMI percentile, and R$\ddot{o}$hrer index) and PIBW (WLR, Broca index, and KDA) were 62.4% and 23.2%, respectably, and the direct method of percent body fat assessment was only 9.3%. The most frequently utilized methods were WLR in under primary and primary school children, and BMI in the middle and high school students and in adults. For primary school students, WLR was the most frequently utilized method up to 2007, but it changed to BMI percentile afterward. Broca Index was no longer utilized since 2008. There were no articles utilizing BMI percentile and R$\ddot{o}$hrer index for obesity assessment in adults. Criteria for obesity assessment were not consistent among research papers: for example, % body fat, 19~40%; BMI, 20~30; BMI percentile, 85th or 95th. In the case of PIBW, 120% of ideal weight was the most frequently utilized criterion for obesity. Based on these findings, we suggest that proper methods and criteria of obesity assessment for each age group should be determined and proclaimed.
