The purpose of this study was to investigate and analyze the correlations between the knowledge of, attitudes toward, and service requirements for dementia among nursing students. A descriptive study design was used. The participants were 584 nursing students attending K university. The collected data were analyzed by descriptive statistics, the t-test, ANOVA, Scheffe test, and Pearson's correlation coefficients using the IBM SPSS 21.0 program. The mean score of dementia knowledge was low($15.86{\pm}4.58$). The area with the highest correct answer rate for dementia knowledge was life impact(64.2%) and the disease progression area(39.6%) was the lowest. The attitude toward dementia ($45.15{\pm}4.59$) and service requirements($89.88{\pm}9.38$) were relatively high. There were positive correlations between dementia knowledge and dementia attitude(r=.11, p=.008) and service requirements(r=.21, p<.001) and between dementia attitude and service requirements(r=.34, p<.001). Therefore, accurate knowledge of dementia was closely related to positive attitudes. In conclusion, this studyis expected to provide the basic data for the development, application and evaluation of dementia education programs for nursing students.

HPI (High-speed Portable Internet) system which provides high speed internet services is going to be commercialized soon. Since HPI provides simultaneously four different service types such as UGS (Unsolicited Grant Service), rtPS (real time Polling Service), nrtPS(non-real time Polling Service), and BE (Best Effort) under different QoS (Quality of Service) requirements and limited wireless channel resources, efficient packet scheduling mechanisms are necessary to increase the utilization of channels as well as to satisfy the various QoS requirements. This study regards the traffic data to be served as time series and proposes a new packet scheduling algorithm based on the nonparametric statistical test. The performance of the newly proposed algorithm is evaluated through the simulation analysis using a simulator that can evaluate the performance of packet scheduling mechanisms under various values of system parameters and measures such as packet delay time, data transmission rate, number of loss packets, and channel utilization.

In this paper, we propose 'a self - conformance system of convergence security provider' to provide basic data for security and reliability of convergence industrial technology, system and service. It is difficult to evaluate convergence security systems, limited to information and communication service providers, unable to check convergence security items, burden of submission documents, difficulty in measuring convergence security service level and we will summarize product and service-based requirements that can be integrated and systematically measure the level of convergence security and define renewed life cycle-based convergence security information and content security and assurance requirements. On the basis of this, each convergence security company declares conformity with the standard itself without the certification of the certification body, and introduces the provider conformity certification system which can manufacture and sell. This will enable the company to strengthen its competitiveness through timely launch and implementation of products and services and cost reduction.

This study aims to analyze types of science museum worksheets developed by elementary pre-service teachers and their perspectives on the requirements and necessity of science museum worksheets. As analysis subjects, this study selected 38 kinds of worksheets and reports developed by 114 elementary pre-service teachers who were in the third year of university of education. In this study, the science museum selected for elementary pre-service teachers to develop worksheets was a national science museum, composed of 'Nature and Discovery Museum', 'Science Technology and Industry Museum' and 'Children's Museum', which was located in a metropolitan city and opened in 2013. The results of this study can be summarized as follows; Firstly, as a result of analyzing the science museum worksheets developed by elementary pre-service teachers, this study found out that the experience type with hands-on and observation techniques applied was most, and as an approach method, direct manipulation, look-in observation and close observation were most. However, although these science museum worksheets were experience-oriented, many of them were survey-oriented ones that suggested too many questions through various exhibits. Secondly, as a result of analyzing requirements of science museum worksheets elementary pre-service teachers thought and described through the word tree of NVivo 10, this study extracted 10 kinds of main themes, out of which the requirement, 'A limited amount of activity should be required', showed the highest frequency. Thirdly, as a result of analyzing the necessity of science museum worksheets elementary pre-service teachers thought and described through the word tree of NVivo 10, this study extracted 9 kinds of main themes, out of which the opinion, 'It is required to help students check an exhibit which may be passed by', was most.

The purpose of this research paper is: (1) to describe the service quality index; (2) describe the data quality index; and (3) describe the anti-corruption index of BPS Trenggalek, Indonesia. The approach chosen is quantitative with the type of survey research. The primary data collection technique was mainly based on a questionnaire distributed to 40 respondents, namely BPS service users in 5 (five) categories: the private sector, the banking industry, academics, offices, or agencies in Trenggalek Regency and universities. The results showed that the quality of BPS services was good and the data quality index where the respondents were satisfied with the data presented by BPS. Meanwhile, testing the anti-corruption index shows that BPS Trenggalek is very anti-corruption in providing services to consumers. The findings of this study suggested that to improve service quality, it is necessary to pay attention to several aspects, including published service requirements, easy requirements to be fulfilled, published procedure information, clear service process flow, published service times, and costs/tariffs are communicated. This study suggests updating data, data relevance, data accessibility, and data completeness to improve data quality. Furthermore, to maintain the very anti-corruption predicate, this study suggests maintaining service by upholding the prevailing ethics and norms.
