The textile industry has benefited from nanotechnology in various fields of application as the use of nanomaterials, and nanotechnology is multiplying. Nanoparticles can increase the performance of textiles by up to 100 times when used in finishing, coating, and dyeing techniques, providing them with capabilities they did not previously possess. Nanotechnology is used in the textile chemical industry to produce sports mats with stain resistance, flame resistance, wrinkle resistance, moisture management, antimicrobial quality, and UV protection. The incorporation of nanomaterials into fabrics can have a significant effect on their properties, including shrinkage, strength, electrical conductivity, and flammability. Various inventions and innovations may result from nano-processed textiles in the future, thus leading to the advancement of science. This article presents the construction of sports engineering structures with high resistance to improve the quality of sports training. The mechanical properties of sports mats are improved with the help of nanotechnology. Strength, elasticity, and tear resistance are among these properties. This method enables the production of elastic, durable, and tear-resistant sports mats.

This study was conducted to investigate the association between socio-demographic factors and attitudes toward antibiotic resistance and consumer's knowledge on antibiotic use for common cold. Telephone survey was conducted between June 24 and July 2, 2009, among 1,015 adults who were randomly stratified by age, sex and area. A total of 921 respondents were included in the analysis. Logistic regression was used to analyze the influence of socio-demographic factors on knowledge and attitudes. A total of 452 respondents(49.1%) recognised that they knew about antibiotic resistance and 769 respondents(83.5%) worried that antibiotic resistance is a serious problem in Korea. A total of 577 respondents(62.7%) had adequate knowledge on antibiotic use and resistance. Multiple logistic regression showed that younger age and higher education level were associated with adequate knowledge. The odds ratio of appropriate knowledge among persons with college degrees was 5.25(95% CI, 2.78-9.90) compared to those with elementary or less education. Sex and income variable were not predictors of adequate knowledge on antibiotic use and resistance. This study showed that consumers with less education had inadequate knowledge on antibiotic use for common cold. Even though consumers in their 40s and 50s thought they knew about antibiotic resistance, there is a need to improve their knowledge. Education campaigns for appropriate antibiotic use have to be differentiated among consumers with different socio-demographic characteristics.

본 연구는 분할기업에서 구성원이 인지하는 조직정치지각과 조직공정성에 대한 인식이 변화저항에 어떠한 영향을 미치는지 살펴보고 이에 대한 방법을 모색하는데 있다. 분석결과, 상사 정치와 동료 정치에 따른 조직정치 지각은 분배공정성, 절차공정성에 의해 최소화되며 조직정치지각은 변화저항을 강화하는 것으로 나타났다. 또한 공정성의 간접 매개효과를 분석하였다. 그 결과 상사의 조직정치지각, 동료의 조직정치지각은 분배 공정성을 매개로 한 변화 저항에 영향을 가진다고 나타났다. 하지만 절차 공정성은 조직정치지각과 변화 저항 간에 매개 효과가 없다고 나타났다. 이에 따라 분할 기업에서 조직구성원들의 변화 저항을 최소화할 수 있도록 분배적 공정성에 많은 관심을 가질 필요가 있다. 조직구성원들이 분배 공정성이 확보되지 못할 경우 조직정치 행동이 유발될 가능성이 높다고 할 수 있다.

본 연구는 혁신활동에만 집중되어 있던 기존연구의 한계를 벗어나 혁신의 확산과 성공을 위해 혁신저항과 리더십의 중요한 역할을 기반으로 조직신뢰의 매개효과와 리더십 종류(공유 리더십, 수직적 리더십)에 따른 혁신저항과의 영향력 차이를 분석하는데 목적이 있다. 연구 모형의 검증을 위해 혁신 중요도가 높은 국내 IT기업 임직원을 대상으로 286부의 설문지를 수집하여 데이터를 분석하였다. 분석 결과, 공유 리더십과 수직적 리더십 모두 혁신저항과 부(-)의 관계가 있는 것으로 나타났으며, 조직신뢰도 혁신저항과의 관계에서 매개효과가 있음을 확인하였다. 또한 공유 리더십이 수직적 리더십에 비해 혁신저항과 좀 더 강한 부(-)의 관계를 형성하고 혁신저항을 낮추는데 공유리더십이 더욱 효과적이라는 것을 알 수 있었다. 특히 IT 스타트업에 존재하는 혁신저항을 극복하는데 조직의 신뢰를 바탕으로 수직적 리더십과 공유 리더십을 상호보완적으로 적용해 보도록 제안하는 바이다.

The IAEA launched the International Project on Innovative Nuclear Reactors and Fuel Cycles (INPRO) and developed the INPRO Methodology to provide guidelines and to assess the characteristics of a future innovative nuclear energy system in areas such as safety, economics, waste management, and proliferation resistance. The proliferation resistance area of the INPRO Methodology is reviewed here, and modifications for further improvements are proposed. The evaluation metrics including the evaluation parameters, evaluation scales and acceptance limits are developed for a practical application of the methodology to assess the proliferation resistance. The proliferation resistant characteristics of the DUPIC fuel cycle are assessed by applying the modified INPRO Methodology based on the developed evaluation metrics and acceptance criteria. The evaluation procedure and the metrics can be utilized as a reference for an evaluation of the proliferation resistance of a future innovative nuclear energy system.

Somatic mutations that lead to hyperactivation of epidermal growth factor receptor (EGFR) signaling are detected in approximately 50% of lung adenocarcinoma in people from the Far East population and tyrosine kinase inhibitors are now the standard first line treatment for advanced disease. They have led to a doubling of progression-free survival and an increase in overall survival by more than 2 years. However, emergence of resistant clones has become the primary cause for treatment failure, and has created a new challenge in the daily management of patients with EGFR mutations. Identification of mechanisms leading to inhibitor resistance has led to new therapeutic modalities, some of which have now been adapted for patients with unsuccessful tyrosine kinase inhibitor treatment. In this review, we describe mechanisms of tyrosine kinase inhibitor resistance and the available strategies to overcoming resistance.

The purpose of this study is to analyze the diffusion period and productivity of smartwork in an organization. Firms are increasingly interested in smartwork for non contact work and working from home because of the corona 19. The smartwork is a new technology that changes face-to-face work in an organization. It helps the work of individuals and organizations regardless of time and place. The theoretical background describes the complexity, system thinking, diffusion theory, smart work, organizational resistance, and productivity. This study analyzes the diffusion period and productivity of smart work through business simulation techniques. A simulation study progresses four stages. There are problem definition, hypothesis establishment and causal loop diagram, model construction and verification, and policy evaluation. The simulation models contain an individual's resistance variables organizational investment and leadership variables related to the operation of smartwork. The organizational investment variables include organizational culture, legal system, implement systems and technology investment. The individual resistance variables include cognitive, attitude, structure and technological resistance. The leadership includes leadership interest variables and performance linkage variables. The simulation executed the changes of a people number adopting smart work and the organizational productivity monthly. As a result of the simulation, many organization members have accepted the smart work innovation after 20 months. The organizational productivity through smart work showed very high value after 16 months. In scenario analysis, the individuals' awareness and attitude resistance showed very important variables to productivity and a personal change of smart work adoption. Meanwhile, The organizational investment showed that the high driving-force increased not productivity and the low driving-force showed decreased low productivity. Also, leadership variables showed a powerful driver for changing smart work productivity. The implication of the study has suggested extending complexity, diffusion theory and organization resistance theory based on simulation methods.
