Implant-supported fixed and removable prostheses provide a proper treatment modality with reliable success. The SS $II^{(R)}$ Implants is a one-stage nonsubmerged threaded titanium implants with Resorbable Blasting Media (RBM) surface developed by Osstem company (Busan, Korea) in October of 2002. This study is to evaluate the survival rate of the SS $II^{(R)}$ Implants for 4 years using radiographic parameters and to review the retrieved implants by the cytotoxicity tests. Since September 2003, 439 SS $II^{(R)}$ implants had been used for 173 patients at Ewha Womans University Medical Center in Korea. Patients consisted of 91 females (52.6 %) and 82 males (47.4 %). The patients' mean age was $42\;{\pm}16$ years, ranging from 21 to 83 years. The follow-up period ranged from 9 to 46 months (mean F/U $24.2\;{\pm}\;10.2$ months). The results are as follows; 1. Of 439 implants, 17 implants were removed and 4-year cumulative survival rate was 96.1%. 2. 82.3% of 17 failed implants were founded during healing phase, and 94.1% of failed fixtures were removed within 5 months after implantation. 3. Crestal bone around the implants was resorbed to 1 mm in 89.0%, to 1 - 2 mm loss of the marginal bone in 8.3%, and the bone loss over 2 mm was occurred in 2.7%. 4. Microscopic examination of the retrieved implants disclosed Grade 0 cytotoxicity in 4 and Grade 1 cytotoxicity in 2 of 6 groups divided according to LOT numbers. Inhibition rate with optical density was acceptable as low as ISO standard.

Ttukseom was once a suburban area that had a government horse ranch for national use and a naenogpo (area of royal farm land). During the Japanese colonial period, a pleasure ground was built at Ttukseom, and after independence, it has been used as a park through the process of urbanization. This study examines the creation of the Ttukseom Pleasure Ground and the process through which the pleasure ground were transformed to a park. This study also explores its landscape and cultural aspects. In the 1930s, Gyeongseonggwedo (京城軌道), a private railway company, built a pleasure ground at Ttukseom to attract passengers, according to the business model of Japanese railway companies, in which recreational areas were developed near railway routes. Mass media portrayed this area as a "rural landscape" in contrast to the city. The Ttukseom Pleasure Ground emerged as a popular summer resort for Gyeongseong citizens. At the same time, it was managed by Gyeongseongbu (京城府). The city of Seoul began to manage the Ttukseom Pleasure Ground following independence, and development plans for Ttukseom as a pleasure ground or a park were continuously drafted but never implemented. Even after Korea's independence, the operation and use of the pleasure ground did not change significantly from the colonial era. In the late 1980s, the Ttukseom Pleasure Ground became the Ttukseom Han River Citizen's Park, and the sandy beach of the Han River was removed. Nonetheless, the previous facilities and major activities such as an open-air swimming pool, camp ground, and areas for boat recreation remained as major park programs. When the urbanization of Ttukseom was completed, its idyllic image disappeared and it became a park instead of a pleasure ground. Since parks expand their programs, it can be concluded that by providing those kinds of programs, the Ttukseom Pleasure Ground transformed to a park.

The importance of service science is emphasized in the modern economy, and the value and necessity of service research still increasing. Since the service research framework was proposed, it has been studied from various perspectives and incorporated into one framework--service research. The direction of service research has been established and a new baseline of research has been established. However, the modern economic and social environment could be described as a new era, the Fourth Industrial Revolution has changed drastically. More and more systematic research on services has become necessary. Therefore, this study analyzed the field of service research in the existing framework. The study suggested how service research could broaden the horizon of service research by studying the 'what'. To do this, we analyzed recent service research trends by themes. We also identified the shortcomings of previous studies about service, and suggested directions and research themes for future research. Based on this study we developed a general approach to the creation of new models from the viewpoint of service science. The authors were also able to develop a general approach to areas such as service innovation, service inference, service solution, and service design leverage. In addition, it is necessary to extend service research and business model to the utilization of service technology. This approach could contribute to forming the basis of future service development, and to utilize social media to create new value of innovative company. The results of this study could contribute to deepening and expanding service research.

Currently while a phase of the Internet as an advertising media is firm, and Internet advertisement utilization of a company rises, and the consumers contact with various Internet advertisements. A lot of Internet advertisements of various forms made with new technology to develop rapidly are executed and will disappear again. Now, It is necessary to classify various types of the Internal advertisement which was made by a sharp environment change, and was tested of the last ten years and to classify expression techniques systematically. At the same time, we have to check a development direction of domestic Internet advertisement and trend. It is a point of time that Internet advertisement must be designed in a macroscopic dimension like the four medium advertisement by an advertisement strategy and an expression strategy. In this paper, first I classified a type of domestic Internet advertising into marketing, an advertisement purpose, an expression form, manufacture technology, and an express on method systematically in five sides so far And I tried to consider the form and characteristics. By next time, while examine change of internet marketing paradigm, I checked trend of recently domestic Internet advertising in accord to a change of consumer's use tendency and a change of Internet advertisement manufacture technology, and tried to consider the development course in the marketing side, the manufacture technical side, and the creative side. Finally, I wish to propose necessity of expression strategy establishment to promote development of the interactive advertisement technique that considered the creative side in order to raise an effect of Internet advertisement.

This purpose of this study is to extract the perceptual types of Organizational Citizenship Behavior(OCB) conceptual domain. OCB is a employee behavior that goes above and beyond the call of duty, that is discretionary and not explicitly recognized by the employing organization's formal reward system, and that contributes to organizational effectiveness. But, as is generally known, OCB is such a fuzzy concept that many researchers have been questioning the exact conceptual domain of OCB. In this context, we try to applicate Q-methodology to find more effective way of explaining the conceptual domain of OCB. Q-sample was constructed by a thorough review on the relevant literature, and P-sample is 14 employees of an manufacturing company. In conclusion, we find three types of the conceptual domain of OCB, that is coworker-oriented, organization-orienteded, and work-orienteed type. The paper ends with suggestions for future research directions.

VOD (Video-On Demand) Services are considered to be one of the most successful data broadcasting services, along with Electronic Program Guides (EPGs). In particular, VOD services provide supplementary revenue for broadcasting companies in addition to the existing subscription fees and advertisement-based revenue. Therefore, each broadcasting company has developed its own VOD service and constantly seeks to improve it. This leads to the development of new VOD services, so developers are considering ways to effectively handle the frequent development needs. In this background, we conducted underlying research to apply the feature-oriented analysis model to the development of VOD services. The feature-oriented analysis model used in this study is the Feature-Oriented Domain Analysis (FODA) one developed by SEI of Carnegie Mellon University. FODA provides a tool for specifying the feature model of a software domain, based on which the developers can determine the configuration of the software with the customers. This study developed a feature model of the VOD service domain and devised the functionalities and test cases in an integrated manner with the feature model. Additionally, we proposed a VOD service development process utilizing the feature model, function specification, and test cases.

When rapeseed oil as the carbon source was used for tylosin production from Streptomyces fradiae TP-1239 was very sensitive to oleic acid. Cell growth was restrained by adding 0.8 g/l of oleic acid to the culture broth. Mutant strain TM-224-1 resistant to 1.2 g/l of oleic acid was obtained by screening in solid and liquid media containing oleic acid. The uptake rate of oleic acid by TM-224-1 was approximately 3.8 fold higher than the parent strain. For comparing the TM-224-1 and the parent strain, batch cultures were carried out in a jar fermentor. Cell growth of TM-224-1 strain was higher than the parent strain after two days of culturing. However, after four days of culturing, it was similar to that of the parent strain. The amount of rapeseed oil consumed by TM-224-1 and the parent strain were 60.5 and 78.2 g/l, respectively. The production and yield of tylosin was aproximately 2.0 and 3.2 fold higher than the parent strain, respectively. From these results, it was concluded that this mutant, which was resistant to oleic acid, has improved tylosin production.
