As the mobile market has been expanded and segmented, a mobile market for kids could be possibly appeared sooner or later. Then, it is necessary to develop a new contents for the new media - a mobile game hardware for kids. These days, kids are most interested in computer games, and they do not have enough time to play with peers. Therefore, in this paper, edutainment game contents based on the wireless internet, are developed. The game could supply kids' learning, fun and especially, peer interaction. In order to develop a game contents through user centered design process, the state of art in mobile hardware and contents was examined, a secondary research and interviews and survey was conducted to understand users. Then, when ideas for game contents has suggested, behavior prototype test was done to verify and modify contents. The suggested game contents in this study, is a occupation simulation game, in which kids simulate their own future career and learn related knowledge in a unintentional way. The result of the study suggests the new direction of edutainment game contents and platform. Also, this study shows the representation of user-centered contents developing process for kids, which could be helpful for the following studies.

The three different batches of an oral sustained release melatonin (MT) delivery system were prepared by aqueous-based fluid-bed coating of the sugar spheres for the evaluation of in vitro release characteristics and plasma concentration profiles in human subjects. The MT contents in 20% coated sugar spheres of three batches (B1, B2 and B3) were $3.3{\pm}0.08$, $2.4{\pm}0.1$ and $2.5{\pm}0.13$ mg per gram of coated sugar spheres, respectively. The release profiles of three different batches had a very similar fashion. However, the release profiles of three different batches had a very similar fashion. However, the release half-lives $(T_{50%})$ of MT from B1, B2 and B3 was $3.70{\pm}0.2$, $5.2{\pm}0.2$ and $4.9{\pm}0.07h$, respectively. Plasma concentration profiles of sustained release 0.2mg melatonin-loaded sugar spheres containing 10% immediate release melatonin in gelatin capsules (B1 and B2) were then evaluated in human subjects. The in vivo plasma concentration profies of the two batches (B1 and B2) were very similar each other and located between the physiological endogenous ranges. The time to reach the peak concentration $(T_max)$ was more advanced in case of B1 when compared to B2. However, there was no statistically significant difference in the maximum concentration $(C_max)$ and the area under the curve (AUC) between B1 and B2. The AUC of melatonin-loaded sugar spheres containing 10% and 20% immediate release MT in human subjects had a good linearity between dose and AUC, regardless of the fraction of immediate release MT, indicating the first order elimination process of MT within these doses. The current oral sustained release MT delivery system may be utilized to treat circadian rhythm disorders if it is proven to be more clinically useful when compared to immediate release MT.

This study investigated the status of kitchen of units in elderly housing facilities and the housing needs of residents. Compared with a lot of comprehensive and alternative studies on elderly housing facilities until now, specialized studies of behavior of elderly housing life and detailed dimensional study have hardly made. Therefore we intend to examine the status of kitchen planning on representative elderly housing facilities in Korea. As the methods of this study, we executed a field study into 4 representative elderly housing facilities in Korea. We visited each 2 units out of the outstanding 4facilities and surveyed the total 8 kitchens. Then we analyzed the space planning and kitchen furniture design of them and the state of kitchen commodities, and measured the kitchen equipment. In addition, we executed interview about satisfaction, preference, use from the residents. As a result, we could find out that depending on whether residents were sewed with meal offered from the facilities or not, the pattern of usage and commodities were quite different. It is necessary to supply the simplest spaces just for preparing some refreshment and tea are suitable. And for the self-cooking residents, much larger cabinets and utility rooms are additionally needed. Safety and functional aspect were quite well designed. Washing machines are usually built-in the kitchen cabinets, and residents are satisfied with this arrangement. We hope that the supplementary study about old people habit and behavior will be a good data of kitchen planning for Korean-type elderly housing units of facilities.

Purpose: As the use of soft tissue fillers becomes more popular, complications such as foreign body granuloma (FBG) are increasing. We report 120 cases of facial FBG and review the available literatures. Methods: 120 patients of facial FBG in our clinic from Mar. 2003 to Feb. 2008 were complied and analyzed. A retrospective chart review was done and patient satisfaction was evaluated with a questionnaire using 5 score scale. Patients with severe inflammation sign or bizarre deformity underwent surgical excision and those with minimal symptoms or a history of hyaluronic acid injection received injection therapy using hyaluronidase. Results: 100 females and 20 males were observed. The average age was 43.7 years (from 16 to 74). 84 patients received surgical therapy and 36, injection therapy. Deformity of facial contour, foreign body sensation and inflammation sign were the three main chief complaints. 84 patients did not know what the injection materials were. The known materials are as follows: collagen, hyaluronic acid, silicone oil, paraffin. 92 cases were performed by unlicensed practitioners, 29 by physicians. Anatomical site most frequently affected by the foreign body granuloma was the cheek (25.8%), followed by forehead (19.2%), lips (15.8%), nose (9.2%), mentum (8.3%), eyelid and eyebrow (4.3%) and temple (0.8%). In 21 patients (17.5%), FBGs were found on multiple sites. Patients with inflammation sign got the highest satisfaction ($3.19{\pm}0.73$) (p=0.001) among 3 chief complaints. And patient satisfaction was statistically higher in surgical therapy group ($3.43{\pm}0.72$) than in injection therapy group ($2.97{\pm}0.88$) (p=0.003). Conclusion: We suggest that it may be beneficial to tailor the type of treatment for FBG relying on wound state and patient's chief complaints. In surgical therapy, resolute approach is necessary to correct facial deformity definitely and to minimize inflammation. Injection therapy could be another option for those with minimal symptoms or a history of hyaluronic acid injection. To prevent foreign body granuloma, not only plastic surgeons but also other physicians should inject soft tissue fillers with great caution and we should warn the public of disastrous consequences associated with illegal medical practice.

Illustrations in advertisement uses various social and cultural codes to stimulate the desire to buy in consumers in the first place, since this is an economic phenomenon orchestrated to sell a product. Hence, factors outside the product per se, such as tradition, social issues and class consciousness are introduced. Especially, in modern advertisement a strategy is adopted to differentiate standard products produced by mass production. In order to do so, such factors as mentioned above become as important as physical characteristics of the product per se and its usage value. As a result, phrases or images used for advertisement can have independent influences on the society irrespective of the sales effects on the product. In this respect, it is fair to state that advertisement reflects the phases and consciousness of a given period as a cultural phenomenon. Therefore, based on the premise of characteristics and roles attributed to the advertisement, this thesis proposes to make a comparative study on the images of women in commercial advertisement in Korea during Japanese Imperialism and China during Cultural Colonial period dating from 1900 to 1945. The starting point of this research will cover the period of foreign trade and Japanese Imperialism in Korea and interference of Western Power in China. It will also investigate on the birth of Korean advertisement by Japanese Imperialists and Chinese modern advertisement along with the modernization of Shanghai. Then, I propose to present the illustrations of women in advertisements based on comparative study of their characteristics and expressions as observed in several case studies both in Korea and China. Connotative meanings in such advertisement will be investigated in the context of political, economic and cultural dominance.

Design, to all of us living in the 21st century, is not just an action that revs up the production and consumption as an added value of an industry, but it is recognized as a broader social and cultural action in practice. The purpose of this study is to broaden the role of design as a principal body producing culture, and to proclaim that design itself has to have self-sufficiency as culture. The study starts from a hypothesis that the action of design should be at the core of cultural industry. The study includes studying the documents on and analyzing the current status and case studies of cultural industry and design policies for macro view. Comparative research and analysis of how designers from three countries, Korea, United States and England, perceive policies is a microscopic part of this study. The methods for this study include survey for quantitative research in Korea, United States and England, and intensive interviews for qualitative research to explain past facts and the current situation of design policies. The survey compares design professionals of three countries, and the intensive interviews are done with manager level design professionals who are both decision makers and policy makers. On order to prove the appropriateness of the survey structure, three pilot studies and a pre-test were carried out. As shown in the verification of the subject of study, if, in the cultural industry which was considered to be the blossom of 20th century, the blind running without intervention of reason still keeps its former state and is unable to go beyond history, we will not be able to enter the age of mentality and fall behind. The value of design that we shall judge depends on the dialectic of 'past' and 'present' regarding the principle of enlightenment, and it will open up a new philosophy, a new civilization and a new world.

In Japan, a country renowned for her traditional respect for handicraft, superior craft techniques have been transmitted from generation to generation. Modern Japanese textiles reinterprete these traditional techniques in a new light and combine them with modern technology, to make modern Japanese industrial textile both futuristic and traditional simultaneously. This combining of new technology and handicraft serves as a reservoir for a remarkable diversity and originality in the development of new technology and design, and constitutes an important trend in modern industrial textiles. The aim of this study is to investigate the developmental background of Japanese textile industry that championed this trend to make the Japanese development unique in modern textile industries and to consider the concept of modern textiles as well as the structural innovation as represented by this new trend, thus contributing to the development of creative textiles for the present and the future. The findings of this study can be summarized as follows. The combining of new technology and traditional handicraft: 1) was made possible by Japanese consciousness that values traditional culture and by early recognition of advanced textile industry, which awarded new meaning and value to the traditional handicraft leading to an expanded social role for textiles. 2) helped construct a modern concept of textiles by pursuing textile media that are state-of-the-art, aesthetic, and highly sensitive to satisfy the requirements of modern industrial textile such as high quality, high performance, and high sensitivity. 3) enabled new design ideas and creation of new styles by implementing structural innovation in industrial textiles that involved diversification of expression, diversity in materials, and emphasis on texture. In short, by combining new technology and traditional handicraft, Japan came up with a new sense of aesthetics that is highly original and high level and with which the rest of the world can easily sympathize, thereby presenting one of the most important guiding principles for future textiles.

Purpose: Endoscopic transnasal correction of the medial orbital fractures cannot be enable to confirm the reduction degree of orbital volume without imaging modalities. We have intended through this study to make a quantative analysis of preoperative orbital volume increment and the reduction degree of that after ethmoidal sinus packing by using CT scan. Methods: In this retrospective study, 22 patients were selected to evaluate the postoperative volume reduction, who took 2 CT scans which are pre- and postoperative under the same protocol. The postoperative CT scan was carried out in about 5 days after the operation with the packing inserted into ethmoidal sinus. The length of bony defect on each section was measured by PACS program and the area of defect was calculated by summing lengths on each section multiplied by the thickness of the section. When the outline of orbit on the slice is drawn manually with a cursor, PACS program measures the area automatically. Orbital volume was calculated from the sum of the area multiplied by the section thickness. Results: The mean dimension of fractured walls was $2.86{\pm}0.99cm^2$. The mean orbital volume of the unaffected orbits was $22.89{\pm}2.15cm^3$ and that of the affected orbits was $25.62{\pm}2.82cm^3$. The mean orbital volume increment of the affected orbits was $2.73{\pm}1.13cm^3$. After surgery, the mean orbital volume of the unaffected orbits was $22.46{\pm}2.73cm^3$ and the mean orbital volume decrease on the surgical side was $2.98{\pm}1.07cm^3$. The estimated correction rate was 118.30%. Conclusion: The orbital volume increment in fractured orbit showed linear correlation with the dimension of fractured area. The orbital volume changes after ethmoidal sinus packing also showed linear correlation with orbital volume increment in fractured orbit. This study showed the regressive linear correlation between the increment of orbital volume and the correction rate. To evaluate the maintenance of reduction state, we think that the further study should be done for comparative analysis of orbital volume change after removal of packing.

Background: Oncologic resection of the scalp confers several obstacles to the reconstructive surgeon dependent upon patient-specific and wound-specific factors. We aim to describe our experiences with various reconstructive methods, and delineate risk factors for coverage failure and complications in the setting of scalp reconstruction. Methods: A retrospective chart review was conducted, examining patients who underwent resection of fungating scalp tumors with subsequent soft-tissue reconstruction from 2003 to 2019. Patient demographics, wound and oncologic characteristics, treatment modalities, and outcomes were recorded and analyzed. Results: A total of 189 patients were appropriate for inclusion, undergoing a range of reconstructive methods from skin grafting to free flaps. Thirty-three patients (17.5%) underwent preoperative radiation. In all, 48 patients (25.4%) suffered wound site complications, 25 (13.2%) underwent reoperation, and 47 (24.9%) suffered from mortality. Preoperative radiation therapy was an independent risk factor for wound complications (odds ratio [OR], 2.85; 95% confidence interval [CI], 1.1-7.3; p=0.028) and reoperations (OR, 4.45; 95% CI, 1.5-13.2; p=0.007). Similarly, the presence of an underlying titanium mesh was an independent predictor of wound complications (OR, 2.49; 95% CI, 1.1-5.6; p=0.029) and reoperations (OR, 3.40; 95% CI, 1.2-9.7; p=0.020). Both immunosuppressed status (OR, 2.88; 95% CI, 1.2-7.1; p=0.021) and preoperative radiation therapy (OR, 3.34; 95% CI, 1.2-9.7; p=0.022) were risk factors for mortality. Conclusion: Both preoperative radiation and the presence of underlying titanium mesh are independent risk factors for wound site complications and increased reoperation rates following oncologic resection and reconstruction of the scalp. Additionally, preoperative radiation, along with an immunosuppressed state, may predict patient mortality following scalp resection and reconstruction.

Purpose: This study was done to investigate the status of disinfection and sterilization in healthcare facilities. Method: A survey of 193 Korean healthcare facilities was conducted from February 8 to March 7, 2013. Data were analyzed using descriptive statistics, ${\chi}^2$ test, Fisher's exact test, one-way ANOVA, Scheffe with SPSS WIN 18.0. Results: Of the healthcare facilities 93.2% had specific guidelines for disinfection/sterilization, but only 47.9% had a committee on disinfection/sterilization for decision-making, less than half (42.7%) conducted regular monitoring of actual practices, while 83.9% had established procedures for recovery in case of problems with the disinfection process and 89.0% kept records and archives of disinfection practices. Cleaning process, selection of chemical disinfectants and process of disinfection and sterilization were found to be inadequate in some healthcare facilities. Perception score for adequacy of medical instruments was 8.10, environmental disinfection was 7.20, and sterilizer management was 8.45 out of a possible 10. Conclusion: Compared to larger institutions, smaller healthcare facilities had less effective disinfection and sterilization management systems, while some facilities showed inadequate practices for medical equipment and general sterilization. Better academic and state-level support is recommended for smaller facilities in order to establish a better system-wide management system.
