Statistics Korea has been diagnosis national statistics every year since 2006. They diagnosis over 200 kinds of national statistics. They have 7 quality dimension used for quality diagnosis. That is relevance, accuracy, Timeliness, Comparability, Coherence, Accessibility. Since we are interest in how well they produce national statistics, comparability has become the most important dimension recently. In this reason, Statistics Korea try to rating quality level and development comparability index for national statistics. This paper propose the practical method of grading the quality level and developing the comparability index of the national statistics.

SIT(Systematic Inventive Thinking), a simplified version of TRIZ, has gained in popularity and used worldwide over recent years. In this paper, the relationship between 5 thinking tools of SIT and 40 inventive principles of TRIZ was examined. For the purpose, many practical TRIZ cases applied in a world-class consumer electronics company were analyzed. The analysis showed that SIT thinking tools were composed of 11 principles in 40 TRIZ inventive principles. Among SIT 5 thinking tools, division and attribute dependency were most frequently used. However, heavily used inventive principles such as preliminary action and beforehand cushioning were not included in SIT. If these principles are additionally reflected in SIT, the effectiveness of the thinking tools will be significantly increased.

There have been proposed various copyright protection protocols in network-based digital multimedia distribution framework. However, most of conventional copyright protection protocols are focused on the stability of copyright information embedding/extracting and the access control to data suitable for user's authority but overlooked the privacy of copyright owner and user in authentication process of copyright and access information. In this paper, we propose a solution that builds a privacy-preserving proof of copyright ownership of digital contents in conjunction with keyword search scheme. The appeal of our proposal is three-fold: (1) content providers maintain stable copyright ownership in the distribution of digital contents; (2) the proof process of digital contents ownership is very secure in the view of preserving privacy; (3) the proposed protocol is the copyright protection protocol added by indexing process but is balanced privacy and efficiency concerns for its practical use.

The purpose of this study was to develop definite and practical marketing strategies for coffee shop managers or preliminary founders through empirical analysis of the effects of desert menu quality characteristics a mainstay of coffee shop-on store choice and revisit frequency. The results of this study are summarized as follows. The results showed that the menu quality characteristics taste, price, hygienic conditions, and health had significant effects on store choice and repurchase frequency through customer satisfaction, whereas originality was rejected due to the lack of menu originality. Both shop choice and repurchase frequency through customer satisfaction were also significant. This suggests that there is a need for the development of a diverse desert menu to increase competitiveness, creation of new customers, and regular customer management.

This study explores interpretations of grandmothers' experiences rearing their grandchildren. For this study, 13 participants provided in-depth interview data, which was analyzed according to Spradely's ethnographic method. Based on the pattern of interpretations, nine concepts were classified into three categories: (i) repentance (compulsive decisions, passivity of the childrearing activity, non-compensation); (ii) sorrow (restrictions on everyday life, renunciation of occupational careers, worsened health); and (iii) satisfaction (decreased isolation in old age, proof of existence for their children, intimacy development with their grandchild). The results of this study show that grandmothers have a higher appreciation for the benefits of relational compensation than for personal cost. Some practical implications are suggested to improve family welfare.

The purposes of this study were to analyze the needs for the balance of work-family and to provide the related policies for dual worker family. We focused on the life area of educare and school. Data were collected from 197 working mothers who have 1 or more children under age 10. The findings were: 1) after-school programs, holidays on every alternate Saturday, arbitrary no school days were not appropriate to the working parents' everyday life patterns, so the paradigm and practical conditions should be adapted to the needs of working parents. 2) the most working parents depended on the kindergarden, but the parents' satisfaction with the quality of service, time duration, the human resource of educare teacher was not sufficient, so these issues should be discussed more profoundly.

The Continuing Professional Development(CPD) program of Korean dentists had probroms that did not resolve for many years. The primary concern of this study is to examine the problems of the CPD program of Korean dentists and to suggest practical guidelines to resolve such barriers. The findings show that the major barrier for improving CPD program is the lack of total quality management. In order to enhance the CPD program, Special plans and resolutions, such as functional organization, recertification system, pool of verified instructor, and evaluation of CPD program, have been suggested.

Observational methods to evaluate postural load have an intrinsic week point that is the problem of reliability in observing postures subjectively, although they have been widely used in assessing risk factors of work-related musculoskeletal disorders in the industry. In this study, observational reliability was discussed based on reviewing several previous studies. Practical guidelines was presented to reduce the observational errors when using video recording for the assessment of risk factors. In addition, previous studies on observational reliability were summarized and analyzed according to body parts to be observed, media for observation, objective measures, analysis, statistics, etc. It is expected that this basic study can be used to increase the applicability and accuracy of the observational methods.

Increased complexity of products and their manufacturing processing demans higher quality control and monitoring than ever before. Therefore, flexible automatization or flexible manufacturing systems (FMS) offer numerous advantages over alternative manufacturing methods. In this state, a in-process monitoring is one of the important flexible automatino system. And as use of NC and CNC machine tool has been increasing, cutting work has automating and it is necessary to develop the automatic production system combined a couple of machine tool. Thus, in this paper to search examination it can measure the tool wear and the tool life and can be more practical research subject.

The Design of Experiment (DOE) is a most practical technique when establishing an optimal condition for production technology in Six Sigma innovation project. This research proposes the assessment of properties of error terms, such as normality, equal variance, unbiasedness and independence. The properties of six nonparametric ranking techniques for checking normality assumption are discussed as well as run test which is used to identify the randomness, and to check unbiased assumption. Furthermore, Durbin-Watson (DW) statistics and ARIMA (p,d,q) process are discussed to identify the serial correlation.
