High Intensity Focused Ultrasound (HIFU) is a noninvasive surgical method mainly targeting deeply located cancer tissue. Ultrasound is generated from an extemally located transducer and the beam is focused at the target volume, so that selective damage can be achieved without harm to overlying or surrounding tissues. The mechanism for cell killing can be combination of thermal and cavitational damage. Although cavitation can be an effective means of tissue destruction, the possibility of massive hemorrhage and the unpredictable nature of cavitational events prevent clinical application of cavitation. Hence, thermal damage has been a main focus related to HIFU research. 2D phased array transducer systems allow electronic scanning of focus, multi-foci, and anti-focus with multi-foci, so that HIFU becomes more applicable in clinical use. Currently, lack of noninvasive monitoring means of HIFU is the main factor to limit clinical applications, but development in MRI and Ultrasound Imaging techniques may be able to provide solutions to overcome this problem. With the development of advanced focusing algorithm and monitoring means, complete noninvasive surgery is expected to be implemented in the near future.

Evaluation of Freeway Congestion Management Using Mesoscopic Traffic Simulator A mesoscopic simulation study to measure the effects of trip generation caused by rampant expansion of residential area around the Kyungbu corridor has been conducted. Some alternatives, which seem to be judgememtally plausible and technically feasible to mitigate such congestion, have been carefully examined and evaluated by the simulation model called INTEGRATION. Alternatives are mostly network improvements. Banpo IC dedicated ramp construction (A1), Seocho IC TSM based weaving elimination (A2), dedicated local and express separation over Seocho-Yangjae segment (A3), Heonleung IC (A4) and Daewang If installations (A5), Pangyo IC improvement (A6), Baikhyun IC (A7) and Dongbaek IC installations (A8) along with Shingal-Pangyo segment capacity addition (A9). The most capital intensive ones are A9, A5, and A4 in that order. A1, A6, A7, and A8 are short in distance but they are also capital intensive and need some construction periods. The least capital driven alternatives are h2 and A3, the h2 is easier to do, but A3 needs traffic diversion scheme during construction. The A1, A7, and A8 have been identified cost effective in terms of speed increase and travel time saving. Along with these results, some limitations and future research agenda regarding simulation have also been presented.

The changes of cosmetic industry regulation in the leading countries, such as E.C., America, Japan, initiated our research to suggest the direction of our cosmetics regulation. These countries are strengthening the post-monitoring system for the safety and cosmetic industry development. We propose the agenda for the development of the industry; the extension of cosmetics range, deregulation of the advertisement, implementation of the ingredient labelling, introduction of the product expiring date. Ultimately. it is necessary to introduce and extend current CGMP to enhance the company responsibility and to reinforce the post-monitoring.

The aim of this study is to investigate fashion activism that supports sustainability by pursuing social transformation through social media. This is achieved by publicizing the environmental and labor problems of the fashion industry. For this study, a literary survey and netnography were conducted from January 2017 to November 2020. We classified and analyzed environmental and labor issues that could be considered fashion activism on social media. The results are as follows. First, movements for conscious consumption appeared as #haulternative, #fashionourfuture, #SecondHandSeptember, and #wornwear projects. These movements are concerned with buying used goods, re-dressing clothes owned by individuals, and transforming and wearing them with new methods. Second, activism for environmental protection includes #fashionOnclimate by Global Fashion Agenda and Sustainable Fashion Matterz' #Watermatterz. These movements are directly involved in learning about the seriousness of environmental destruction caused by the fashion industry and participating in environmental protection with critical awareness. Third, the #whomademyclothes and the Clean Clothes Campaign are activism for improving the working environment, and are playing a role in publicizing labor issues by informing the general public about inadequate working conditions linked to the fashion industry. Thus, fashion activism on social media examined in this study can contribute to visualizing chronic problems that hinder sustainable development within the fashion industry.

This cross-sectional survey research carried out with the inquisitive agenda on satisfaction of the translation outcomes as performed by human translation and (machine translation) post-editing. The survey group consisted of 166 Korean translators primarily working with the English, Chinese, and Japanese languages. They were asked to rate the satisfactory level with accuracy, fluency, idiomatic expression, and terminology in the Richter's scale of four. The result reveals that human translation is more satisfactory than post-editing with respect to accuracy, but it is uneasy to assert that accuracy is unsatisfactory in post-editing. On the other hand, the Korean translators are less satisfied with fluency, idiomatic expression, and terminology than accuracy. It can be assumed that although human translation is more satisfactory than post-editing, the accuracy of post-editing seems to be more acknowledged than fluency, idiomatic expression, and terminology, which lead the translators to take the accuracy of raw machine-translation products and to go on to improve the fluency, idiomatic expression, and terminology. Nevertheless, Korean translators believe Korean idiomatic expressions cannot be satisfactorily produced in post-editing, while fluency and terminology can be improved in post-editing.

The Chinese Communist Party's 'with-Chinese-characteristics' discourse proclaims its superiority in reflecting people's genuine needs without poisonous partisan politics, as in Western democracies. The Party's Consultative Democracy is key to this superiority. To evaluate Consultative Democracy in Contemporary China from a perspective of popular sovereignty, which is the essential purpose of every kinds of democracy, this research looks into Consultative Democracy from two dimensions: theoretical dimension and institutional dimension. Theoretically, CCP's Consultative Democracy seeks its theoretical sources from their traditional thought as well as from Marxism, and especially emphasizes CCP's leadership to fulfill the consultation results. And through the analysis of various field investigations, we find that there are some prominent problems in grass-roots society's institutional mechanism for Consultative Democracy, such as insufficient connection between institutional innovation and existing legal system, inefficient consultation, insufficient representation of consultative subjects and weak motive force for sustainable development. By legitimizing certain groups or individuals as representatives in their consultative process, CCP can be de-legitimize by containing, dividing or denouncing others so that critics can be co-opted, neutralized or isolated. The CCP's consultative and representational processes are different from taking policy inputs as dialogue or negotiation as in democracies, it is a dynamic, largely one-way process of enforcement and direction with a clear political agenda: maintaining Party hegemony.

This paper shows light on the concept of smart tourism destination as a future of tourism development, especially in the context of problems associated with developing countries. This study substantiates the case of smart tourism development in mountain destinations as an affordable and needed future of the contemporary era. This conceptual study is based on secondary literature on Smart Cities, Smart Tourism Destinations, and Tourism in Himachal Pradesh. The Indian state of Himachal Pradesh has been considered as a study area to acknowledge major tourism-related challenges, especially in mountain locations. Consequently, the dots are connected between existing challenges and solutions that smart tourism holds. It turns out that for the development of mountain tourism destinations such as Himachal Pradesh in the Indian Himalayas, investments in smart infrastructure are required. By developing smart infrastructure, a new USP can be made, a supportive environment for new local businesses, new employment opportunities, enhanced tourist experience and an overall raised standard of living for locals. Considering all factors, it leads to a highly competitive tourism destination. All tourism destinations located in the Himalayan mountains show somewhat the same tourism challenges as Himachal Pradesh, India. Therefore, this paper brightens the path of destination planners towards the development agenda of smart tourism destinations and shows how smart tourism infrastructure can be deployed for better management of tourism destinations.
