Background: Skin cancer is a global health problem that can be prevented by protective behavior promoted by nurses. In Turkey, only few studies have examined current knowledge of nurses related to skin cancer and to reveal their attitudes towards sun exposure and current protective behavior. Materials and Methods: This descriptive cross-sectional study was performed from March 11 to May 30, 2013 with a study sample of 310 nurses working in two state hospitals located in Karab$\ddot{u}$k and Safranbolu. Results: Mean age of the nurses was $30.3{\pm}6.89$ years and 96.1% of them had graduated with a Bachelor degree. The participants were predominantly female (n=284). Knowledge level about skin cancer was significantly higher for females compared to males. Conclusions: Nurses do not have sufficient knowledge about skin cancer and are not adequately protecting themselves from ultraviolet light, the primary risk factor for skin cancer. While they demonstrated a responsible attitude towards avoiding sunburn and the need for adequate sun protection, they do not fully appreciate the extent to which the sun can cause skin cancer and that they lack full understanding about the need to protect the skin from burning and to avoid long term sun exposure in Turkey.

Due to the nature of semi-submergible drilling rig, various equipments are arranged in a limited space, and therefore the many types of outfitting holes passing through the hull structure are densely arranged and that is required the detailed structural strength evaluation in terms of ULS and FLS by class or client. Particularly, semi-submergible drilling rig has a variety of global load which affects the structure strength around holes compared to general commercial ship, and its response of stress is also complicated, so it is difficult to carry out the prediction design of structural strength evaluation and reinforcement. In this regard, this paper presents a case study on the evaluation of structural strength for the various holes and large openings of semi-submergible drilling rig conducted by our company, as well as an established hole verification procedure.

Most of people do not remind of 'Who is domestic medical device business?' A lot of people that Johnson and Johnson, GE and Philips and other foreign companies belong to medical device company. In fact, local enterprises small place based on world market. Local medical device industry's production has grown up rapidly last 10 years. Sales increased nearly 3 times from trillion and 500 billion KRW in 2004 to 4 trillion and 600 billion KRW in 2014. The production record constantly increased owing to safety and good quality of domestic medical devices. As many as 59% of medical devices made in Korea is exported to 198 countries in the world. Currently, medical device industry in the world has been given considerable attention. Cognition and awareness are very much low. Medical device industry, high income creating industry, is said to next generation industry to increase scale, and Korea does not follow world flow. The industry is given support from the government that is not enough. Korean enterprises have small scale among a lot of global enterprises. Being interested in development of medical devices, the author selected department of IT at college.

In this treatise, a survey was conducted on American female consumers to confirm the possibility of segmenting the American cosmetic industry by classifying lifestyles and analysing differences in consumer behavior, and also to provide global marketing strategy for entry into the American cosmetics industry by Korean companies. The results of the analysis provided three categories of American female consumer lifestyles. The first is the "practical conservative" type(58 people) who are fairly indifferent to or uninterested in external changes. The second is the "pro-active sensitive" type(48 people) who are interested in external changes and want to live a leading life. The last is the "neutral economical" type(54 people) who resemble characteristics that are in between the previous two types. The study has showed there was a difference in consumer motivation, considerations during selection, factors associated with shop choice according to consumer classification. It provides evidence that lifestyles can be a criteria in segmenting the American cosmetics market.

This paper addresses the analysis and design of fuzzy control systems for a class of complex single input single output nonlinear systems. Firstly, the nonlinear system is represented by well-known Takagai-Sugeno (TS) fuzzy model and the global controller is constructed by compensating each linear model in the rule of TS fuzzy model. The design of conventional TS fuzzy-model-based controller usually is composed of two processes. One is to determine static state feedback gain of each local model and the other is to validate the stability of the designed fuzzy controller. In this paper, we propose an alternative of the design of TS fuzzy-model-based controller. The design scheme is based on the extension of conventional optimal control theory to the design of TS fuzzy-model-based controller. By using the proposed method the design and stability analysis of the TS fuzzy model-based controller is reduced to the problem of finding the solution of a set of algebraic Riccati equations. And we use the recently developed interior point method to find the solution of AREs, where AREs are recast as the LMI formulation. One simulation example is given to show the effectiveness and feasibility of the proposed fuzzy controller design method.

Fuzzy Systems which are based on membership functions and rules, can control nonlinear, uncertain, complex systems well. However, Fuzzy logic controller(FLC) has problems; It is difficult to design the stable FLC and FLC depends mainly on individual experience. Although FLC can be designed using the error back-propagation algorithm, it takes long time to converge into global, optimal parameters. Well-developed linear system theory should not be replaced by FLC, but instead, it should be suitably used with FLC. A new methodology is introduced for designing THEN-PART membership functions of FLC based on its well-tuned state feedback controller. A example of inverted pendulum is given for demonstration of the robustness of proposed methodology.

Considering the complex relationship between fashion curating and the critical approach of fashion exhibition reviews, this study explores the current state of fashion criticism in museology, focusing on fashion designer exhibition reviews of Fashion Theory. The author selected eighteen exhibition reviews of individual fashion designers' works from 1997 on to the current 2020 issues of Fashion Theory, which provides an interdisciplinary forum to analyze fashion as a cultural construction. The author performed a systematic review that qualitatively summarizes and/or synthesizes the findings of the studies on the topic with the process of a systematic review, such as key question formulation, analytic framework building, evidence mapping, critical appraisal, and evidence synthesis. The results of this study are as follows. First, the exhibition reviews included almost all stages of the inclusive fashion criticism model, based on an artifact study. Second, they reflected various critical discourses that offered current interpretations of historical and contemporary fashion. Third, they showed that fashion criticism in the museum context is the result of an interdisciplinary collaboration of various fashion agents. Finally, they offered a bridge for crossing the boundaries of various scholarly fields, as they combine multidisciplinary scholarship with object-based methods.

As the internet traffic type and size have bun diversified in recent years, the GMPLS-based distributed control and management protocol have surfaced as a serious issue for dynamic optical lightpath setup. In this reason, we investigated and analyzed network performance and protocols using global information-based link state approach and local information based link state approach. We calculated connection setup time, required control bandwidth and setup blocking probability that made from network update period and threshold metrics according to traffic arrival rate. The evaluated results will be used in broadband network and adopted for high speed network in the future widely.

Black carbon, which is a by-product of combustion of fossil fuel and biomass burning, is the component that imposes the largest uncertainty on quantifying aerosol climate effect. The direct, indirect and semi-direct climate effects of black carbon depend on its state of the mixing with other water-soluble aerosol components. The process that transforms hydrophobic externally mixed black carbon particles into hygroscopic internally mixed ones is called "aging". In most climate models, simple parameterizations for the aging time scale are used instead of solving detailed dynamics equations on the aging process due to the computation cost. In this study, a new parameterization for the black carbon aging time scale due to condensation and coagulation is presented as a function of the concentration of hygroscopic atmospheric components and the black carbon particle size. It is shown that the black carbon aging time scale due to condensation of sulfuric acid vapors varies to a large extent depending on the sulfuric acid concentration and the black carbon particle size. This result indicates that the constant aging time scale values suggested in the literature cannot be directly applied to a global scale modeling. The aging time scale due to coagulation with internally mixed aerosol particles shows an even stronger dependency on particle size, which implies that the use of a particle-size-independent aging time scale may lead to a large error when the aging is dominated by coagulation.

Bans on TBT based antifouling paints have been drafted since 1999 by meetings 42, 43, 45 and 46 for the MEPC (Marine Environmental Protection Committee) of the International Marine Organization, and decided finally at a Diplomatic Conference of the IMO in October 2001. It was a key issue that there should be a global prohibition on the application of organo-tin compounds as biocides in Anti-fouling systems by Jan. 2003, and a complete prohibition on te presence of organo-tin compounds on ships by 1 Jan. 2008. This paper suggests a method to design International Anfi-fouling system cretificate, Record of anti-fouling system, Endorsement of the Records, Declaration on Anti-fouling System, Port State Control and reform(legislative) associated a law.
