This study examined the effects of reeducation of core basic nursing skills on competence, confidence and anxiety in nursing students. We collected the data from 176 2nd grade nursing students. Reeducation of core basic nursing skills was conducted from December 20th to 23rd, 2016. Data were analyzed by SPSS 21.0 program. As the result of reeducation, significant improvement was found in competence(t=-11.57, p<.001), confidence(t=-10.21, p<.001) and considerable decrease was recognized in anxiety(t=-4.76, p<.001). In conclusion, reeducation of core basic nursing skills can help students to improve their overall competence and confidence, and also to reduce their anxieties as they start their first clinical practice. Therefore we suggest that more systematic and continual reeducation of core basic nursing skills should be applied to each grade of nursing students who are facing their clinical practice in hospital

A Product Line (PL) is a set of products (applications) that share common assets in a domain. Product Line Engineering (PLE) is a set of principles, techniques, mechanisms, and processes that enables the instantiation of produce lines. Core assets, the common assets, are created and instantiated to make products in PLE. Model Driven Architecture (MDA) is a new software development paradigm that emphasizes its feasibility with automatically developing product. Therefore, we can get advantages of both of the two paradigms, PLE and MDA, if core assets are represented as PIM in MDA with predefined automatic mechanism. PLE framework in the PIM level has to be interpreted by MDA tools. However, we do not have a standard UML profile for representing core assets. The research about representing PLE framework is not enough to make automatically core assets and products. We represent core asset in PIM level in terms of structural view and semantic view. We also suggest a method for representing architecture, component, workflow, algorithm, and decision model. The method of representing framework with PLE and MDA is used to improve productivity, applicability, maintainability and qualify of product.

Korea operates a national core technology system to protect important technologies at the national level. In the administrative procedures of the nation's core technology, the deliberation process conducted by qualitative evaluation by related industry experts is important. As the need for timely and appropriate technology protection increased, the need to shorten the time required for administrative procedures related to the designation and removal of national core technologies was raised. Therefore, this study studied the criteria for identifying patents related to national core technologies. For AMOLED, a national core technology in the display field, LDA topic modeling was applied to related news and papers to derive important technology and its trends, and mapped to AMOLED advanced technology processes under Article 5 of the Industrial Development Act to prepare criteria for discrimination. Since then, objective verification has been conducted through AMOLED national core technology patents already known. Through this study, patents related to AMOLED national core technologies can be identified, which can shorten the time for related administrative procedures.

Recently, the leak of domestic core technology of major business in Korea and the subsequent damage, has been increasing every year. Financial losses due to this leak are estimated to be about 220 trillion, which is equivalent to the gross budget of Korea Besides, the majority of the leaks are caused by former and current staff members, cooperated businesses, scientists and invesment companies. This shows that the source of the leaks are internal personnel. In this manner, we can infer that the management and plan of personnel security has not implemented sound practices to prevent technology leak by people. Therefore, this thesis suggests classifying methods of technology leak through clustering, one of the data mining methods about the information of internal personnel to prevent core technology leak from businesses.

Product Line Engineering (PLE) is an effective reuse methodology where common features among members are captured into core assets and applications are developed by reusing the core assets, reducing development cost while increasing productivity. To maximize benefits in developing systems, business case analysis for PLE is essential. If the scope for core assets is excessively broad, it will result in high cost of asset development while lowering reusability. On the other hand, if the scope is too narrow, it will result in a limited applicability which only support a small number of members in the domain. In this paper, we propose a process for business case analysis for PLE and for deciding economical analysis of core asset scope. Then, we define guidelines for each activity of the process. Since variability often occurs in PLE, we significantly treat the variability of features among members in detailed level. By applying our framework for business case analysis, one can develop core assets of which scope provide the most economical value with applying PLE.
