Back ground: Human skin is continuously exposed to UV irradiation. Ultraviolet irradiation of human skin cause sunburn cell which is relevant to the apoptosis of keratinocytes. In the epidermis, apoptosis inducing factors and anti-apoptotic factors probably exist to maintain the integrity of keratinocytes. Objective: The purpose of this study was to investigate the exsistence of apoptosis inducing factors and anti-apoptotic defence factors by evaluation of UV induced apoptosis in cultured human keratinocyte and other keratinocyte cell lines(A-431 cells, KB cells) and its susceptibility of UV induced apoptosis in various conditions. Method: In this study, the percentages of apoptosis, necrosis and cell viability of irradiated human keratinocytes and othe keratinocyte cell lines by MMT assay and AO/EO stain. The percentages of those were measured before UVB irradiation and 8, 24, 48 hours after UVB irradiation. Also, the same evaluations were performed with irradiated human keratinocytes cultured without growth factor and with enough growth factors, both results were compared with each other. And the effect of cycloheximide, a protein synthesis inhibitor was evaluated. Also that of aurintricarboxylic acid(ATA), an inhibitor of endonucleases which play an important role in inducing apoptosis of human keratinocytes was evaluated. Result: Human keratinocytes and other keratinocyte cell lines(A-431 cells, KB cells) were cultured in vitro developed maximal apoptosis 48 hours after irradiation, keratinocytes were more resistant to UV induced apoptosis than the others. The withdrawal of growth factors from keratinocyte and addition of cycloheximide decreased the cell survival rate following UV irradiation and increased the induction of apoptosis. And ATA inhibited UV induced apoptosis. Conclusion: These results indicate that human keratinocytes have both anti-apoptotic factors and apoptosis inducing factors to maintain the homeostasis. And survival signals mediated through growth factors or cellular proteins are responsible for the resistance to apoptosis observed in keratinocytes in vitro.

Soft tissue expansion is widely used technique in oral & maxillofacial reconstruction and provide new method of reconstruction in posttraumatic alopecia, post burn, wide scar, congenital deformity, benign tumor, tattoo, etc. Expanded tissue flaps have the advantage of increased vascularity, proximity to the defect, and similarity of color and texture. They also preclude the need to advance flaps from distant sites. Tissue expansion can be used to form a well vascularized cavity to accomodate and nourish bone grafts. The following report describes the uses of tissue expanders by allowing bone grafting to correct both soft and bony defects of mandibular region

The purpose of the study was to investigate social support, depression, drinking and smoking in college and working females. The convenience sample consisted of 169 college females and 133 working females. Data were collected from March to May 2000. Social support was measured by the 6-item Social Support Questionnaire which assesses the size of the emotional social support network and satisfaction with social support. The Center for Epidemiologic Studies Depression scale was utilized to measure the level of depression symptoms. The average number of drinks and cigarettes smoked per week during the previous month was assessed. Results indicated that college students had more social support than working females. However there were no significant differences in satisfaction with their support. depression. drinking and smoking between two groups. College females who smoked cigarettes were more depressed and had less social support than those who did not smoke. Also college females who drank alcohol were more depressed than those who did not drink during the previous month. However, the level of social support and depression were not associated with drinking and smoking among working females. Based on the results, it is suggested the application of various interventions to deal with drinking and smoking behavior among college and working females.

Today we experience chaos. The waste of human and material resource and the canalization of almost all creative effort into blind alleys bear witness to the fact that our common life has lost its coherency. Development industrial and advanced in science and technology have created a new dimension. Today, all people of the world are neighbors, and neighbors resources on a hitherto undreamed of scale are within the potential reach of all. The inherited structure of a smaller, outgrown world, however, stands in the way of the integration of our lives in the terms of the present wider dimension. And to achieve a livable life today, then, we must reorient ourselves, and create forms in terms of present historical conditions. Instead of allowing both a further haphazard accumulation of scientific discoveries and a planless technological expansion. it is our task of establish an organic interconnection of the new frontiers of knowledge. Integration, planning, and form are the key words of all progressive efforts today the goal is new vital structure order, a new form (visual language) on a social plane, in which all present knowledge and technological possessions may function unhindered as a whole. The pictogram as visual communication, the language of vision, is one of the strongest potenitial means both to reunite man and his knowledge and to re-form man into an integrated being. The visual language is capable of disseminating knowledge more effectively than almost any other communication media. With it, man can express and relay his experiences in object form. Visual communication is universal and international-it knows no limits of tongue, vocabulary, or grammar, and it can be perceived by the illiterate as well as by the literate. A pictogram can convery facts and ideas in a wider and deeper range than almost any other means of communication. It can reinforce the static verbal concept with the sensory vitality of dynamic imagery. It can interpret the new understanding of the physical world and social events because dynamic inter-relationships interpenetration, which are significant of every advanced scientific understanding of today, are intrinsic idioms of the contemporary medias of visual communication.

It has often been said that the biggest mass media are TV, Radio, Newspaper, Magazine. In America the fifth media next to the four kinds of media is Computer or the Technique Concerning to Computer. In the new media age rushing to us there has been great changes in the world of advertisement. As the words 'new media' literally means, it demand avoidance from the traditional ad style and initiation to the new lifestyle and approaches totally different from the old ones for all media, agent, and customers. The rapid progress to the worldwide new media times links with the development of splendid new media times(multimedia times in the narrow sense) through commercial on-line service. CD-Rom, PCtelecommunication, internet, etc. Multimedia functions not only as new media but also plays such roles as advertisement, sales promotion, salesman and money collection, and management and marketing communication. These days internet has been growing rapidly because of its advantage for telecommunication, entertainment, and media for education as well as of its strength for the means of electronic trade. Internet is being used widely in all economic fields, e.g. cooperation with suppliers, management of goods and stocks, reduction of purchase expenses, amangement of goods and stocks, reduction of purchase expanses, management of new customers. As for media, we could distinguish the existing media, such as media for prints, image, and movies from the new media without such traditional form, i. e. multimedia computer. CD-Rom, laser disk, up-to-date faximile, portable PCS, electronic publishing, etc. These new services pertain the technical features of Computerization in common, which have changed the existing one-way services into two-way modes. The advertisement through these new media Internet has been rising up rapidly as new ad-media because of its possibility of two-way communication and prompt purchase right after receiving the advertisement.
