The aim of this study was to investigate the antibacterial properties of chitosan silver nanocomposites (CAgNCs) using pathogenic Vibrio ichthyoenteri as a bacterial model. Results of agar disc diffusion and turbidimetric assays showed that CAgNCs could inhibit the growth of V. ichthyoenteri in concentration dependent manner. The minimum inhibitory concentration (MIC) and minimum bactericidal concentration (MBC) of CAgNCs were 75 and $125{\mu}g/mL$, respectively. Furthermore, CAgNCs treatment induced the reactive oxygen species (ROS) level in V. ichthyoenteri cells in concentration and time dependent manner, suggesting that it generates oxidative stress, leading to bacterial cell death. The field emission scanning electron microscope (FE-SEM) images of CAgNCs treated V. ichthyoenteri exhibited strong cell membrane damage than un-treated control bacteria. MTT assay results showed the highest cell viability (22%) at $75{\mu}g/mL$ of CAgNCs treated bacteria samples. The results from this study suggest that CAgNCs is a potential antibacterial agent to control fish pathogenic bacteria.

HgTe and HgTe/CdTe core-shell structured nanocrystals(NCs) were synthesized in aqueous solution by colloidal method. HgTe and HgTe/CdTe NCs structure showed very similar XRD patterns because of the same lattice constant and crystal structure of both samples. The absorption and photoluminescence(PL) spectrum of the synthesized HgTe NCs revealed the strong exitonic peak in the IR region. The PL spectrum of HgTe/CdTe NCs have the intense peak in about 700nm shorter than that of HgTe by 400nm. The photocurrent measurement of colloidal NCs are performed using He-Ne laser for light source. The photocurrent of HgTe NCs shows the instant increased current response to light, but HgTe/CdTe NCs revealed a decreased current when lighted to the sample. In the vacuum condition, it shows reverse result that current increased under the illumination of light and it is thought that the molecules like the hydro-oxygen gas in the air give an important effect on the current mechanism.

This study was conducted to investigate the fitness of major courses according to the development and application of new curricula based on the NCS (National Competency Standards) of health-related departments at junior colleges. To accomplish this, 300 students of the health-related departments at junior colleges were surveyed from March 11 to March 30, 2016. The overall findings showed that their awareness of NCS, intent of integration and understanding of curriculum contents had a significant effect on the fitness for linkage and combination with existing education. Competency unit elements based on the newly developed NCS (job, work, qualification and training standardization of major courses) were linked with existing education. And students - who accept this - are rapidly assimilated into the new curriculum contents. In particular, they have a high understanding of the integrated development of standardized curricula between three major departments, unlike existing textbooks. In conclusion, the high perception and understanding of knowledge integration education are expected to have a positive effect on healthcare education, establishing an early health-related NCS system in the future, and improving site fitness for development of the contents of NCS.

This study was carried out to investigate the effect of sulfuric fertilizers on allylisothiocyanate(allylNCS) content of upland Wasabia japonica Matsum cultivated in heating condition in the winter season. The rhizome's growth characters following soil application of sulfur dust were not significantly different compared to control, though its soil acidity and available sulfur content was higher than other treatments. Total sulfur content of plant was increased by soil application as compared to foliar application and allylNCS content of rhizome increased up to 22.8% in the sulfur dust treatment. The result showed that soil application was effective for supplying $SO_4^{-2}$ in upland Wasabia japonica Matsum when cultivated in heating condition. In the analysis of correlation coefficients between growth and quality characteristics, allylNCS content of rhizome showed the significantly positive correlation with total sulfur content of shoot, rhizome and allylNCS content of shoot.

The reference guide for the cost of establishing the digital documents has been used as a basis for establishing the budget for the construction of the knowledge information resource. However, due to the abolition of the nominal unit price notification in terms of IT projects, it is necessary to conduct research to convert the standard of the current labor force grade standard to the national incompetency standard (NCS). In this study, we investigate and revise the system and contents of the current knowledge information cost estimation model. In specific, i) we conducted gap analysis of cost estimation model and existing NCS model. As the contents conforming for the construction of the knowledge information resource were not adoptable, we define the description of the construction of the knowledge information resource and to identify the core elements of NCS prior to the improvement of the cost model. ⅱ) then we proposed improve the cost model considering integration with newly proposed NCS model for knowledge information construction job. In order to ensure the validity of the application of NCS development and cost estimation model, the experts reviewed relevant contents and made plans for improvement by using experts from supply and demand groups of various fields of national knowledge informatization projects.

Purpose As job market squeezes and more institutions have been requiring NCS(National Competency Standards) based recruitments, the importance of NCS has been growing. Among the 10 domains of NCS, the most relevant one with MIS(Management Information Systems) field is 'information ability', which is becoming more important with the advent of the fourth industrial revolution era. The purpose of this study is to investigate the effect of college students' information ability on their career preparation behavior. Design/methodology/approach In this study, we set up a process model to comprehend the effect of college students' information ability on career preparation behavior based on social cognitive career theory. For research model testing, 561 questionnaires were used for empirical analysis through structural equations modeling. Findings Empirical analysis showed that information ability positively influenced college students' career preparation behaviors for employment. In addition, this study presented a process model explaining the effect of information capability on career preparation behavior. In order to strengthen the information ability of college students, not only university-level efforts, but also MIS discipline efforts should be accompanied. Other academic and practical implications are discussed.

This study aims to suggest implications on develop and operate NCS curriculum by analyzing of differences in perception and educational needs of university students, graduates, human resource managers(HR managers) on NCS basic job skill. The respondents of survey are composed of 533 university students in K university, 730 graduates and 106 HR managers. The major findings are as follows: first, the results showed that the importances of all competencies recognized by HR managers was higher than those of university students and graduates. And graduates perceived their level of competencies as higher than those of university students. Second, the needs for self-development skill, technical skill, and problem-solving skill was the highest within the students and graduates, meanwhile, the needs for the mathematical skill, resource management skill, and the organization understanding skill were low. In contrast, the results of this study showed that the HR managers has the high needs for self-development skill, communication skill and problem-solving skill. Also, HR managers has the low needs for mathematical skill, resource management skill, information skill, technical skill, organizational understanding skill, and job ethics. Based on the above results, we proposed the necessity to develop and apply the NCS curriculum considering the education needs recognized by current students, graduates, and HR managers.

Recently Korea has stepped into a stage of sluggish development, and the unemployment of young people has become a major issue. Especially in 1998 IMF economic shock was influential in formulating government policy and social economic structure on employment. Restructuring now becomes everyday words and further restructuring is already under way. Owing to the growing economic crisis and resultant unemployment and initial appointment shall be considered conditional. Young job seekers are grappling with mastering their native language and unnecessary experiences. These unnecessary experiences are needless waste of time and money. Educational system in university may be affected by environmental changes in population of students and business crisis. Sometimes the departments made a very low rate of employment may be abolished or merged in university. The government will demand us in the work of reform by doing NCS. The government is now ask to teach, train and employ students on the basis of NCS especially in high-school, job training center, and college and university. NCS has advantages and disadvantages. NCS may reduce waste of time and money to make unnecessary experiences, provide standard course to prepare educational system. It will be a big help to adapt properly and make better employment system. The most negative element of the program is application to humanities and social sciences by the same standard with technology and engineering department in the university. Standardization of each educational course will not react quickly to rapidly changing situations in the future.

This study analyzed the qualifications necessary and manpower required in the Jeju nail art and make-up industry. We aimed to investigate the relationship between NCS education and national technical qualifications. For this study, 164 participants were given a questionnaire, and the collected data were analyzed via frequency analysis and multiple regression analysis using SPSS Ver. 18.0. The results of this study are as follows: 1. Matching job seekers with available positions was more difficult in nail art businesses than in makeup businesses. The main routes by which practitioners found jobs were Internet job sites and acquaintances. In addition, experience was the first consideration in hiring employees. 2. Those in high positions had less intention of employing students who had received NCS education, than those in lower positions. Intention to employ NCS graduates was high in businesses that found their employees through Internet job sites, vocational training institutes, acquaintances, or colleagues. Nail art workers prioritized NCS educational units in the following order: nail care, nail shop hygiene, gel nails, cosmetic nail removal, and tips/wraps. Makeup workers had the following priorities: basic makeup, wedding makeup, makeup shop safety, and hygiene management. They also mentioned basic occupational skills such as communication skills, interpersonal skills, and problem solving skills. Moreover, the new national licensing system was found to reflect competency in the most important skill sets.
