This study is to develop a human resource (HR) security framework, and related HR security indicators in the context of information security. The HR security framework consists of three constructs, personnel assurance, personnel competence, and personnel security control. Based on the framework, HR security management indicators are derived as 26 indicators in 9 items out of 3 categories. An empirical research has been performed to verify the relevance and consistency between the indicators by conducting a questionnaire-based survey. Also, interrelationships between the proposed indicators and HR related security level were analyzed by the multiple regression analysis. As a result, the proposed hypothesis were mostly accepted, showing the significant relationships between the indicators and security level.

The objective of this study was to explore hygiene issues by analyzing the importance and performance of personal and school hygiene in school foodservices. Questionnaires were administered to 634 students (10 high schools) in the Busan area. Exactly 29% of respondents had received hygiene education. The average score of importance of students' personal foodservice hygiene was 3.81/5.00, and the performance score was 3.48/5.00. The same scores for school foodservice hygiene were 4.37/5.00 and 3.67/5.00, respectively. Regarding importance and performance of personal foodservice hygiene, students who had received hygiene education showed significantly (P<0.01) higher scores than those without prior education. In terms of importance of school foodservice hygiene, students who had received hygiene education showed significantly higher scores for environment hygiene (P<0.05) and equipment hygiene (P<0.05). Additionally, among grid analysis in personal foodservice hygiene, the areas of high importance and low performance included 'washing hands before the meal', 'using a designated cup for the water purifier', and 'keeping clean around the leftover container'. As for school foodservice hygiene, the same area was 'cleanliness of tray'. These findings suggest that hygiene education needs to be extended to more students, and for school foodservice hygiene, a cleaner environment should be created using equipment hygiene management, including emphasis on ensuring cleanliness of tray.

Dietary data of 538 middle school students have been analysed to identify the contribution of specific foods to absolute intake and between-person-variance in nutrient consumption. The 24-hour-dietary-recall method had been used to collect the data required. Contribution of specific foods, in terms of ranking order for both absolute intake and between-person-variance have been observed. Ranking order of food for absolute intake was given based on the percen of contribution whereas the ranking order of foods for between-person-variance was given based on the percent of contribution whereas the ranking order of foods for between-person-variance was given based on a coefficient fo variation. As a result, for most of the nutrients(except cholesterol), the ranking order of foods for the between-person-variance was quite different from that of absolute intake. The results indicate that to identify between-person-variance of nutrient intake in an epidemiology study, foods with a high ranking in between-person-variance should be included in developing the food frequency questionnaires rather than foods which showed a high ranking in absolute intake.

To survive in the trend of the fourth industrial revolution, companies are putting a lot of attention and effort into personalization services using the latest technologies such as big data, artificial intelligence and the Internet of Things, while entrusting third parties to handle personal information on the grounds of work efficiency, expertise and cost reduction. In such an environment, consignors need to check trustees on a more effective and reasonable basis to ensure personal information safety for trustees. This study used AHP techniques to derive the importance and priority of each item of "Personal Information Safety Assurance Measures" for financial companies and trustees, and objectively compared and analyzed differences in perceptions of importance between financial institutions and trustees. Based on this, the company recognizes the difference between self-inspection of financial institutions and inspection of trustees and presents policy grounds and implications for applying differentiated inspection standards that reflect the weights appropriate for the purpose.

Recently, IT technology such as internet, mobile, and IOT has rapidly developed, making it easy to collect data necessary for business, and the collected data is analyzed as a new method of big data analysis and used appropriately for business. In this way, data collection and analysis becomes easy. In such data, personal information including an identifier such as a sensor id, a device number, IP address, or the like may be collected. However, if systematic management is not accompanied by collecting and disposing of large-scale data, violation of relevant laws such as "Personal Data Protection Act". Furthermore, data quality problems can also occur and make incorrect decisions. In this paper, we propose a new data governance maturity model(DGMM) that can identify the personal data contained in the data collected by companies, use it appropriately for the business, protect it, and secure quality. And we also propose a over all implementation process for DG Program.
