One of the key mission is to develop and prompte the use National Competency Standards, which is defined to be the systemization of competencies(knowledge, skills and attitudes) required to perform duties at the workplace by the nation for each industrial sector and level. This provides the basis for the design of training and detailed specifications for workplace assessment. To promote the data-driven service improvement, the commercial product Splunk was introduced, and has grown to become an extremely useful platform because it enables the users to search, collect, and organize data in a far more comprehensive, far less labor-intensive way than traditional databases. Leveraging Splunk's built-in data visualization and analytical features, HRD Korea have built custom tools to gain new insight and operational intelligence that organizations have never had before. This paper analyzes the NCS homepage. Concretely, applying Splunk in creating visualizations, dashboards and performing various functional and statistical analysis and structure without Web development skills. We presented practical use and implications through case studies.

Though a dozen of different software life cycle models are suggested, there is no universal model which can satisfy all the characteristics of software. Organizations mix and match different life cycle models to develop a model more tailored for their systems and capabilities. We suggest overlapped-concurrent development life cycle model that is more suitable in various software development environment. Firstly, we divided the development process into abstract and implementation stage. Abstract stage is from software concept phase to detailed design starting time, and implementation stage is from detailed design phase to system testing phase. Next, the abstract stage introduced the overlapped phase concept that begins the next phase when the step is completed 20% by applying pareto's law. In the implementation stage, we introduced the concurrent development which the several phases are performed some time as when one use-case (UC) is completed the next development phase is started immediately. The proposed model has an advantage that it can reduce the inefficiency of development resource greatly. This model can increase the customer satisfaction with a great product at a low cost and on a short schedule. Also, this model can contribute to increase the software development success rate.

As most companies in the world are much interested in the overseas market as well as in the domestic market, many Korean food service enterprises came to focus on extending their branches to the overseas market. However, lack of business strategies including market research, marketing strategies, localization, etc. has made them continue to fail in market entry. The purpose of this study is to develop entry mode of determinants of Korean food service enterprises, considering their characteristic factors and environment factors in the overseas market. To do this, companies which have a head quarter in Korea and over 2 year business experience in the overseas market were chosen and used for a self-administered questionnaire survey. Statistical processing, including descriptive statistics, logistic regressing analysis, and multi regression analysis using an SPSS/PC 12.0 statistical package were conducted The result is as follows. First, explanation suitability was 85% of the entry mode in the overseas market. Second, as business size was smaller, product differentiation was higher, and CEO's will for success in the overseas market was higher, independent entry mode in the overseas market was likely to he chosen. Lastly, as the uncertainty of demand and trade barrier were lower, and a sociocultural gap was smaller, independent entry mode in the overseas market was likely to be chosen.

This study attempts to develop a mass production product standardized by the application of high pressure extraction cooking(HPEC) in order to suggest a desirable direction for the development of salt contained standardized chicken stock. In our experiment on chicken stock with varying its salt content, the total free amino acid content was highest in S3, which contained 0.3% of salt In addition, when the total content of free amino acid was divided into the contents of essential amino acid, palatable amino acid, and other types of amino acid, they showed the same distribution as the total content of free amino acid. In addition, the total content of palatable amino acid was highest among the specimens. In the results of investigating the palatability of chicken stock according to salt content, saltiness increased with the increase of the salt content, but no significant difference was observed in preference for saltiness. It is believed to have come from the difference in the sensory evaluators' preference for saltiness, and it shows that the salt content has an effect on sweet taste, delicate taste, fishy smell, and color. In particular, specimen 83, which contained 0.3% of salt, showed the highest content of palatable amino acid, and the highest level of delicate taste in sensory tests, suggesting the correlation between palatable amino acid and delicate taste.

No matter how small amount of heavy metals it may be cause skin allergies through percutaneous adsorption when existing in cosmetic products as impurities. In order to develop a highly sensitive method for simultaneous determination of $Pb^{2+},\;Fe^{2+},\;Cu^{2+},\;Ni^{2+},\;Zn^{2+},\;Co^{2+},\;Cd^{2+},\;and\;Mn^{2+}$ in coloring agents and cosmetic products with rapidity and accuracy, we carried out the determination on ion chromatography. All of these metals are well separated through a bifunctional ion-exchange column(IonPac CS5A) and detected by post-column reaction and spectrophotometric detection. The calibration graphs are linear($r^2>0.999$) in the range $0.1{\sim}1000{\mu}g/mL$. Detection limits for 200 ${\mu}L$ of sample solution are at the level of ${\mu}g/L$, which is sufficient for judging whether the product is safe or not. The relative standard deviations(RSDs) of the retention time and the peak area are less than 0.21 and 1.24%, respectively. The recovery rates are $97{\sim}104%$. The new method was applied to analyze the amount of heavy metals which were contained in 22 cosmetic products and 11 coloring agents.

Lip make-up products can be easily taken into body with food. For this reason, those products are requires to meet lots of qualifications compared with other cosmetic products. In addition, concerns about safety on synthesized tar pigments is constantly issued. Thus, demand of natural pigments is gradually increased and many kinds of natural pigments have been developed. However, there are some problems when natural pigments are applied to cometic products instead of synthetic ones. There is a reason that most of natural pigments consist of hydrophilic materials of sort of anthocyanin, but the existing lip make-up products is anhydrous oil dispersion type without water consisting oil and wax. Therefore, when watersoluble natural pigments are applied to anhydrous lip make-up products, color expression is lower and phase separation occurs due to the instability of the product. In addition, natural pigments have disadvantages that they can easily change by pH, heat and sunlight. There are troubles of stability because it is not easy to adjust for these factors in case of anhydrous forms. Aim of study is to develop lip make-up products which have not only safe to human but being high in expression of color by using natural pigments and securing stability of colorant as natural pigments are offered to polyol in oil emulsion. Then, lip make-up products which have heavy moisture while having not dryness that is created when the moisture evaporates are developed.

This study investigated changes in quality and sensory characteristics of soy sauce (Kanjang) with added Astragalus membranaceus (AK) to develop a new soy sauce product with improved sensory characteristics. The pure salinity slowly increased, but AK 10% decreased. The pH was a constant in all samples. The soluble solid content (Brix) increased after 2 months, but AK 10% decreased. With increased addition of Astragalus membranaceus (AM), the optical density increased after 4 months. The amino nitrogen increased in soy sauce with AK 5%. The total free amino acid content gradually increased in soy sauce with AK 5% aged for 6 months. As the addition of AM increased, the crude protein level decreased, but there was no difference between AK 0% and 5%. The sensory tests of AK 5% after 6 months showed higher acceptance. According to the aging period, the acceptability of AK 5% was the best. The results showed that soy sauce with of AK 5% and aged for 6 months exhibits greatly enhanced quality and sensory characteristics. Therefore, it is expected to be used as a natural resources in seasoning area.

Recently, interest in emotional technology has escalated and its application has extended to many fields, from both an industrial (product) and service (culture, tourism, medical, education, advertising) perspective. Moreover, culture has become a fundamental aspect of modern industry, playing key roles in: gaming, exhibitions, performances, sports, tourism, design, edutainment, as well as various content distribution industries. The prospect of applying emotional technology for cultural content industries makes up for more than half of the 'plan-manufacture-distribution-marketing' process, and thereby also serves as driving force for the growth of a nation. The primary objective of the following research is analyze successful cases from the past through utilization of emotional technology, and to speculate on efficient directions for future research into developing emotional contents. To achieve this, some of the key terms have been defined and elaborated for the sake of clarity. The terms are as follows: emotion, emotion engineering, science of emotion, emotional technology, and emotional contents. Furthermore, studies were conducted based on the six different fields surrounding CT R&D to observe how projects involving emotional technology have succeeded both on a national and global scale. Based on this analysis, this research aims to develop personalized 'Concierge' service-providing contents, contents designed to maximize performance ability of humans, and contents that could be controlled simply via emotion to effectively spread the culture of Korea by focussing on 'fusion' content development. The following research data may hopefully serve as a basic reference to industries navigating towards emotional content development.
