In the present society, our current technology associated with bakery industry has been improved as much as technical development can get abreast of the Western one where the bread has originated and has been awarded and ranked in the highest level of many bakery or pastry competitions. In these trends, many people are running for high value added business such as bakery industry and bakery $caf{\acute{e}}$, etc. with big interest. However, high labor cost of technician and difficulties in human resource management become obstruction factors in the growth of the bakery industries. Therefore, in this paper, the designed system for both dividing and rounding dough quickly and exactly at the same time was studied. The main function of this system is to divide the original dough into 3 tracks and then, to place 4 doughs in the inner track, 12 doughs in the mid track, 20 doughs in the outer track, totally 36 doughs in a routine. It takes much energy because 36 doughs can be completed in a routine. Therefore, this system uses hydraulic pressure and a 0.75Kw induction motor is used for dough rounding. This system can make primarily fermented dough into 36 divided doughs very quickly and exactly on a guide panel at the desired weight by dividing it within 1-9 seconds and by rounding each within 1-9 seconds. This system is very effective in bakery industry to minimize labor cost and it is expected to supply more hygienic products to the customers.

Repetitive transcranial magnetic stimulation (rTMS) is a non-invasive neuromodulation technique which can change cortical excitability in targeted area by producing magnetic field pulses with an electromagnetic coil. rTMS treatment has been used to treat various neuropsychiatric disorders including depression. In this review, we evaluate the literature on rTMS for depression by assessing its efficacy on different subtypes of depression and different technical parameters. In particular, we focus on the results of randomized clinical trials and meta-analyses for depression after the US Food and Drug Administration approval in 2008, which acknowledged its efficacy and acceptability. We also review the new forms of rTMS therapy including deep TMS, theta-burst stimulation, and magnetic seizure therapy (MST) that have been under recent investigation. High frequency rTMS over left dorsolateral prefrontal cortex (DLPFC), low frequency rTMS over right DLPFC, or bilateral rTMS is shown to be effective and acceptable in treatment for patients with non-psychotic, unipolar depression either as monotherapy or adjuvant. Deep TMS, theta-burst stimulation and MST are promising new TMS techniques which warrant further research.

Environmental Impact Assessment(ElA) in Korea has been used to improve environmental conservation and decision-making since environmental impact statement(EIS) was introduced in 1981 with the promulgation of the Environmental Preservation Act in 1977. which replaoed the Pollution Control Act legislated in 1%3. Together with a rapid growth of environmental perception as well as the diversification of development activities, however, it has recently bring about a strong demand for a new assessment process related to the strategic level of policies, plan, programs. In order to overcome such a limit in ElA system, Prior Environmental Review System(PERS) was introduced for assessment of administrative plans mainly concerned with development projects in 1993. In 1999. the regulations for PERS have been established by an amendment of the Basic Environmental Policy Act.Therefore the foundation of EIA system to integrate environmental concerns in planning processes and project works has been refonned. However the results of the execution of PERS were somewhat insuffident due to the institutional and technical matters. As the world's attention turns to sustainability and the considerations of cumulative effects, the concept of strategic envirorunental assessment(SEA) has taken on more significance and urgency and increasing number of countries and international organizations now undertake some form of SEA. The term SEA, however, is variously defined and understood, generally it means a formal process of systematic analysis of the envirorunental effects of development policies, plans, programmes and other proposed strategic actions. This process extends the aims and principles of EIA upstream in the decision-making process, beyond the project level and when major alternatives are still open. In this paper, we are discussing the significance of SEA and its relevance to EIA and the international trends and institutionalization of SEA. In conclusion we are discussing the comprehensive developing plan for SEA in Korea, then proposing a plan to make institutional arrangements for its application.

The present study explored studies directed at elucidating the effectiveness of Korean medicine in the treatment of sterility and systematically analyzed the trends of studies on sterility. The standardization and objectification based on results for this study may contribute to the development of effective Korean medicine in reducing sterility. In the annual tendency of sterility-related clinical studies, the number of papers began to increase rapidly from 2000, and 15 papers were published from 2000 till 2011. Then, in the technical journals publishing them, The Journal of Oriental Obstetrics & Gynecology published 13 the most papers. In the institutions to which the first authors belonged, Dongguk University Hospital had 5 the most papers. In the number of test subjects was also analyzed and as the result the studies with 1~9 were the most as 10. In the study design analysis, there were 10 case reports, 5 case series and 4 before and after studies. In the analysis of intervention methods, there were 10 papers where only the Korean medicines were given, next 6 papers where the acupuncture and moxibustion were added, and 3 papers where the Korean medical therapies and other subsidiary therapies were used. In the analysis on the existence of pattern identification, there were 12 papers with the pattern identification, 6 without the pattern identification and 1 with the four constitution identification. In the IRB approval, 18 or most papers had not received the IRB approval and just 1 paper got the IRB approval. When the sterility-related clinical studies published in the Korean medical journals were surveyed, it turned out that there are no RCT studies and there is just one study with the IRB approval. And there were 6 papers without the pattern identification of Korean medicine. So, it seems necessary in the future to improve the papers in these respects for the development of Korean medicine sterility treatment with a good basis through the more systematic and accurate study method.

This study examined Korean Public Relations trend and social acceptance in 1960s. It centers on the acceptance conditions of PR concept, corporate PR and governmental PR. It analyzed PR recognition and practical activities of the general corporations, financial institutions and public corporations in dealing with corporate PR. It also analyzed Korean governmental PR through examining the structure of governmental PR system, PR activities in rural communities and the police. In those days, PR concept had been misused to no small degree and not been accepted correctly that the necessity to let people know PR in its proper meaning was raised. Laying emphasis upon the technical side, corporate PR activities had centered on publicity. Especially, at that time, the banks, the insurance companies and the public corporations had perceived the importance of PR and implemented a set of PR activities. It can be said that a special feature in government PR in 1960s lies in the expansion of the public information system and reinforcement of PR policies. Also, PR in rural communities had been doing to give information relating to agriculture technique and to improve the living conditions of the farm area. The importance of PR in police had been on the side of promoting relations with people and improving treatment of the people by policeman.

The paper aims to analyze the logic and power of open source software (OSS), and to show the ways in which Korean government and companies support developing countries in the field of software development. Many developing countries are considering software industry to be a strategic industry due to the fact that software industry seems to be labor-intensive, or rather knowledge-intensive industry. In this regard, developing countries without huge financial investment can achieve certain level of economic development while leveraging software industry. Concerning software development tools, among recent trends OSS has been regarded as a viable alternative software development tool for developing countries. In developing countries, OSS is believed to resolve some difficulties caused by proprietary software such as Microsoft Windows, which is too expensive to buy for users and developers in low-income developing countries. In this sense, OSS has been considered as only solution for software developing because OSS is able to reduce the cost of software development and to enhance the technological capabilities of developing countries. In addition to the benefit of low cost, we have to shed light on the business model of OSS that is not to sell software licence, but to provide technical support and services. In order to use OSS as much as they can, developing countries have to invest for educating human resources who can develop and implement software system using OSS. These OSS-related policies can lead developing countries to developed countries.

The Turfgrass Information Center' database provides 5,340 descriptive records including 638 referred papers and 1,370 technical reports concerning 'Zoysia'. The database focused on researches on golf courses and lawn care industries. The researches provide informations on seed technology and use of plant protectant for pest management in turf management industries. The purpose of this study is to analyze and classify the research contents of zoysiagrasses which have been published in Korean journals. The total number of research papers published in Korean journals were 274 including 102, 38, and 134 in the 'Botanical', 'Environmental' and 'Cultural' researches, respectively. Publication in foreign journals by Korean investigators were not counted in this research. Research fields concerning golf course maintenance and plant protectant are believed to be necessary when compared to international trends. Moreover, advanced research efforts for the development of new cultivars with various environmental and disease resistance should be accomplished.

The purpose of this study is to explain and predict trends the AI development process based on AI technology patents (total) and AI reporting frames in major newspapers. To that end, a summary of South Korean and U.S. technology patents filed over the past nine years and the AI (Artificial Intelligence) news text of major domestic newspapers were analyzed. In this study, Topic Modeling and Time Series Return Analysis using Big Data were used, and additional network agenda correlation and regression analysis techniques were used. First, the results of this study were confirmed in the order of artificial intelligence and algorithm 5G (hot AI technology) in the AI technical patent summary, and in the news report, AI industrial application and data analysis market application were confirmed in the order, indicating the trend of reporting on AI's social culture. Second, as a result of the time series regression analysis, the social and cultural use of AI and the start of industrial application were derived from the rising trend topics. The downward trend was centered on system and hardware technology. Third, QAP analysis using correlation and regression relationship showed a high correlation between AI technology patents and news reporting frames. Through this, AI technology patents and news reporting frames have tended to be socially constructed by the determinants of media discourse in AI development.
