  • Chile is characterized by the largest seismicity in the world which produces strong earthquakes every $83{\pm}9years$ in the Central part of Chile, where it is located Santiago, the capital of Chile. The short interval between large earthquakes magnitude 8.5 has conditioned the Chilean seismic design practice to achieve almost operational performance level, despite the fact that the Chilean Code declares a scope of life safe performance level. Several Indexes have been widely used throughout the years in Chile to evaluate the structural characteristics of concrete buildings, with the intent to find a correlation between general structural conception and successful seismic performance. The Indexes presented are related only to global response of buildings under earthquake loads and not to the behavior or design of individual elements. A correlation between displacement demand and seismic structural damage is presented, using the index $H_o/T$ and the concrete compressive strain ${\varepsilon}_c$. Also the Chilean seismic design codes pre and post 2010 Maule earthquake are reviewed and the practice in seismic design vs Performance Based Design is presented. Performance Based Design procedures are not included in the Chilean seismic design code for buildings, nevertheless the earthquake experience has shown that the response of the Chilean buildings has been close to operational. This can be attributed to the fact that the drift of most engineered buildings designed in accordance with the Chilean practice falls below 0.5%. It is also known by experience that for frequent and even occasional earthquakes, buildings responded elastically and thus with "fully operational" performance. Taking the above into account, it can be said that, although the "basic objective" of the Chilean code is similar to the SEAOC VISION2000 criteria, the actual performance for normal buildings is closer to the "Essential/Hazardous objective".

  • Purpose: The purpose of this study was to evaluate the effectiveness of a peer cervical cancer prevention education program on Korean female college students' knowledge, attitude, self-efficacy, and intention. Methods: A quasi-experimental pretest-posttest design with a non-equivalent control group was used. The participants were 58 female college students in a metropolitan city in Korea. The sample consisted of an intervention group (n=28) that participated in a peer education program and a control group (n=30). Data were measured using self-administered questionnaires at two time points: prior to the intervention and after the intervention. Results: Compared to the control group, the experimental group reported significantly positive changes for knowledge, attitude, self-efficacy, and intent to practice cervical cancer prevention behaviors. Conclusion: The findings of this study indicated that a peer education program developed for Korean female college students was a useful and effective intervention strategy to promote cervical cancer prevention behaviors in Korean sociocultural contexts.

  • There are numerous and evidential findings that TCDD (2, 3, 7, 8-tetrachlorodibenzo-Pdioxin, or dioxin) is a potential carcinogen and general toxin in rodents. flowever, human risk assessment for dioxin exposure has been a topic of debate, owing in part to the large animal interspecies differences in its toxicity. We review dioxin-related reports indicating its toxicity, toxic effects in animal, and human epidemiologic findings. The intent of this paper does not provide a causal inference about chronic human diseases related to dioxin exposure. This summary would give a valuable clue for a researcher to conduct or design a further dioxin-related study.

  • This study is a thesis about the hair art reflected minimalism which is expanded to various art fields using minimum formative measures minimalism is a kind of modern art trend. It is analyzed theoretically that the works of this researcher approaching minimalism and consideration of minimalism about hair, flexible clothes and artistic costume. It is defined that the "hair art" is "aesthetic hair", and I include my three works approaching minimalism that are researched, extended, made. I spread the works which have minimalism characteristic by design intent, concept, title, color, ingredient, size and detail, consider the hair art works theoretically and present the basis and method of scholar study minimalism art trend. I think that succeeding studies related to the hair art should be continued. I expect that various work activities of hair art artists and scientific breakthrough via theoretical thesis about the work of themselves.

  • All critical equipment installed aboard naval ships and submarines is required to be shock-qualified by tests on the MIL-S-901 shock test machines where testing is practical. The intent of the shock requirements is to produce combat vessels which are resistant to the underwater explosion weapon attack. To efficiently design equipment for passing a series of shock tests, the shock environment of the shock test machine should be clearly identified. In this paper, the shock characteristics of the MIL-S-901 Medium Weight Shock Machine(MWSM) are reviewed, based on the existing test data. An analytical model for the MWSM is also discussed.

  • Objective : This article reviewed China's intent and aim of the failed attempt to register Traditional Chinese Medicine(TCM) as UNESCO's Intangible Cultural Heritage, its process and implication as a policy of 21st Traditional Chinese Medicine(TCM) promotion on the landscape of North East Asian medical geopolitcs. Methods : This article utilized mainly the discourse analysis of vernacular Chinese journals and newspaper reports. Conclusions : It is needed to design effective strategies for securing Traditional Korean Medicine(TKM)'s identity and authenticity to cope with so-called 'Chinese Medicine Domination Project'.

  • As many brands use social media influencers (SMIs) on Instagram to advertise, not disclosing advertised content affects how consumers perceive these influencers. The purpose of this study was to investigate two objectives: 1) recent advertising disclosure types on Instagram and 2) the factors that affect consumer responses towards Instagram influencers posting advertised content. Using an experimental 2x2 between-subjects design (N=200), the findings show that "sponsored" and "paid partnership with" are two recent types of ad disclosures. However, both factors are insignificantly different from each other. Also, ad disclosure condition enhances the trustworthiness of the influencer than no disclosure. Ad skepticism, source credibility, and the level of persuasion strongly relate to how consumers perceive Instagram influencers advertising for brands. These factors enable consumers to assess if the influencer is a reliable source of information when faced with advertisement. Ultimately, using disclosure gives full information to consumers about the persuasive intent, as well as increases positive consumer responses towards the influencer who discloses, thereby, enhancing the ethical use of the influencer advertising strategy and long-term consumer relationship.

  • A small hall thruster with a thrust of about 10 mN and a specific impulse of about 1500 s is being developed with an intent to control or maintain the orbits of small satellites. The total mass, consumed electric power and efficiency of the thruster are approximately 10 kg, 300W and 30%, respectively. The thruster system consists of a hall thruster with a cylindrical cross section, a power processing unit and a Xenon(Xe) gas feed system. Laboratory examination of the thruster performance finds that the thruster meets the design specification.
