This study was conducted to identify the using self-nail products for the purpose of developing indicators to respond to changes in nail industry due to the evolution of consumption patterns caused by the spread of self-nail culture. The final analysis of 293 survey was conducted on female adults living in South Gyeongsang Province from September 1, 2018 to October 30, 2018. The study found that women in their 20s were more interested in nail care than in most cases. The main route of obtaining nail-related product information was the higher the use of SNS as the age was younger(${\chi}^2=185.048$, p<.001). According to a survey of 165 people who have experience with self-nail products, 53.3 percent of 'paste stickers' were the most common, followed by 39.4 percent of 'paste nail tips' and 7.3 percent of 'home care products'. Looking at the disadvantages of self-nail products, between groups under their 50s and over 50s group saw a significant difference(${\chi}^2=27.032$, p=.008). For those in their 50s or younger, 'the inconvenience of daily life' was considered a disadvantage. On the other hand, people in their 50s and older considered 'short duration' as a disadvantage. The lower the age, the higher the willingness to use continuously(${\chi}^2=14.308$, p=.006).We found that there were differences in preference for self-nail products according to age. It was noticed that there were differences in satisfaction and persistence. This suggests the need for more specific follow-up studies on the use of self-nail products by age group. Therefore, this research aims to present basic data for the development of direction and custom program for the professional nail industry to advance, thus providing basic data to help the development of nail industry in South Gyeongsang Province.

Optimum stand density of alfalfa (Medicago sativa L.) varies with locations and climates. Stand density is one of the factors that determines herbage yield, forage quality and persistence of alfalfa. As establishment costs increase, the question arises whether present population densities are optimum for obtaining maximum herbage yield and forage quality. The objectives of this study were: 1) to determine the optimum plant density for highest herbage yield and forage quality for the dehydrated alfalfa industry under Edmontons climatic conditions in Alberta, Canada; 2) to compare herbage yield and forage quality of the cultivars 'Algonquin' and 'Vernal' grown at a range of stand densities. Alfalfa seedlings of both cultivars were either transplanted at spacings of 6, 10, 15 and 25 cm or direct seeded at the 4.5 cm plant spacings, providing population densities of 494, 278, 100, 45 and $16plants/m^2$. The experimental design was a randomized complete block with a split-plot arrangement having three replicates; the main plots consisted of two alfalfa cultivars Algonquin and Vernal, and the sub-plots were the five population densities. The cultivar Vernal had significantly higher annual yield than did the cultivar Algonquin. There was no significant effect of plant density on herbage yield. There was no difference in crude protein (CP) between the two cultivars. At the first cut, there was a significant quadratic effect of plant density on CP content and the greatest CP occurred at the 100 plants/m2 density. Crude protein was not affected by plant density at the second cut. Acid detergent fiber (ADF) and neutral detergent fiber (NDF) were not affected by plant density. The cultivar Algonquin usually had a lower ADF and NDF than cultivar Vernal. In conclusion, high population densities ($278plants/m^2$ or more) of alfalfa did not improve herbage yield and forage quality compared with low plant population densities ($100plants/m^2$ or less) of alfalfa.

Ocean warming can have significant negative impacts on population genetic diversity, local endemism and geographical distribution of a wide range of marine organisms. Thus, the identification of conservation units with high risk of extinction becomes an imperative task to assess, monitor, and manage marine biodiversity for policy-makers. Here, we surveyed population structure and genetic variation of the red seaweed Gracilaria vermiculophylla along the coast of China using genome-based amplified fragment length polymorphism (AFLP) scanning. Regardless of analysis methods used, AFLP consistently revealed a south to north genetic isolation. Populations at the southern coast of China showed unique genetic variation and much greater allelic richness, heterozygosity, and average genetic diversity than the northern. In particular, we identified a geographical barrier that may hinder genetic exchange between the two lineages. Consequently, the characterized genetic lineage at the southern coast of China likely resulted from the interplay of post-glacial persistence of ancestral diversity, geographical isolation and local adaptation. In particular, the southern populations are indispensable components to explore evolutionary genetics and historical biogeography of G. vermiculophylla in the northwestern Pacific, and the unique diversity also has important conservation value in terms of projected climate warming.

Background: Job satisfaction of dental hygienists has been discussed continuously in dental hygiene research. It has been the most representative performance variable in dental and human resource management. However, in quantitative research, most of the studies have analyzed the causal relationship with variables related to dental hygienists' job satisfaction. The existing qualitative research contains only the studies that targeted dental hygienists with an experience of more than 10 years. The present study aimed to understand and to characterize the job satisfaction of dental hygienists with an experience of 2 to 10 years and to compare it with the qualitative research on dental hygienists with an experience of 10 or more years. Methods: An in-depth interview of dental hygienists with 2 to 10 years of experience working in 10 dental clinics was conducted. For data analysis, Giorgi's analysis method was used. Results: After analyzing the meaning of job satisfaction of dental hygienists, 180 semantic words and 19 subcategories were derived. The results of the interview were categorized into for central meanings: recognition and rewards, work experience and ability improvement, occupational characteristics, and work characteristics. Recognition and rewards included workplace recognition, patient recognition, self-effort and recognition, and the feeling of being rewarded. Work experience and ability improvement included various work experiences and factors relates to improving the work ability. Occupational characteristics included professional job, interest and persistence, job extensibility, and no burden of employment. Work characteristics included working conditions and separation of work and private life. Conclusion: The development of tools to measure the level of dental hygienists' job satisfaction after long-term service and to conduct follow-up research regarding ways and effects to improve job satisfaction is needed.

The market size of engineered nanoparticles is rapidly increasing due to the fast application of nanotechnologies into different industries and consumer products. The development of new technology and materials has improved human's quality of life, but it also entails the possibility of exposure to new materials. In this study, we compared the distribution in the body by the inflow of silver nanoparticles having another diameter and shape at 1 h or 24 h after injection via the tail vein. And, we compared the cell composition and cytokine concentration in BAL fluid, and histopathological changes. As results, discharge of silver nanoparticles having small diameter and sphere shape was more rapid than that of big diameter or plate shape. It is estimated that the toxicity in liver and lung was proportional to accumulation level. The persistence of inflammation was also longer in mice treated with plate shape. Consequently, we suggest that the first choice of silver nanoparticles having small diameter and sphere shape in applying is desirable.

Purpose: This study examined the effects of a physical activity promoting program based on the Information-Motivation-Behavioral Skills (IMB) model on physical activity and health outcomes among obese older adults with knee osteoarthritis. Methods: This study utilized a randomized controlled trial with a convenience sample of 75 obese older adults with knee osteoarthritis in a university hospital. The older adults in the intervention group participated in a 12-week program involving weekly group sessions and monitoring calls with education booklets and video clips for exercise dances, while those in the control group received an usual care. Outcomes were measured using self-report questionnaires, anthropometrics, and blood analyses. The intervention effects were analyzed using Mann-Whitney U test and ANCOVA. Results: The mean age of participants was 74.9 years with 84.0% women. The intervention group at 12 weeks showed significantly greater improvements in self-efficacy for physical activity (F=81.92, p<.001), physical activity amounts (Z=-2.21, p=.044), knee joint function (F=15.88, p<.001), and health-related quality of life (F=14.89, p<.001) compared to the control group. Among obese-metabolic outcomes, the intervention group at 12 weeks showed a significant decrease in visceral fat mass (F=7.57, p=.008) and improvement in high-density level cholesterol (F=9.51, p=.003) compared to the control group. Conclusion: Study findings support the need for an IMB based physical activity program for promoting physical activity, knee function and health outcomes in obese older adults with knee osteoarthritis. Longitudinal studies are warranted to confirm the persistence of obese-metabolic effects in clinical settings.
