본 논문에서는 네트워크의 구성 정보를 바탕으로 상위 수준에서 하위 수준으로 정책을 변환할 때 나타나는 기존 정책과의 충돌을 탐지하고 순응시키는 메커니즘을 소개한다. 대규모 네트워크는 라우터, 스위치, 방화벽 침임 탐지 시스템, 일반 호스트 등과 같은 다양한 종류의 장비로 구성되어 있으며. 이러한 것들은 각기 다른 접근 일 제어 형식을 가지고 있다. 따라서 트래픽에 대한 일괄적인 통제가 어렵고, 외부의 공격에 대한 신속하고 효과적인 대응이 불가능하다. 또한 대규모 네트워크를 구성하고 있는 장비들을 제어하기 위해서는 그러한 장비들이 포함되어 있는 서브 네트워크의 세부 점보와 각 장비의 고유한 설정 규칙을 필요로 한다. 이러한 점은 대규모 네트워크를 상위 수준의 계층에서 관리를 어렵게 한다. 때문에 하부 계층의 구조나 정보와는 독립적으로 추상화된 고수주의 보안 정책 설정을 위한 도구가 요구된다 이것은 상위 수준의 보안 정책 표현 기법, 하위 수준의 보안 정책 기법, 상위 수준의 보안 정책과 네트워크 구성 정보를 바탕으로 하위 수준의 보안 정책을 도출하는 기법 하위 수준의 보안 정책을 실제 네트워크 구성 요소에 적용하는 기법 등의 네 가지 연구로 구분된다. 본 논문에서는 이 네 가지의 연구와 기법을 바탕으로 관리 네트워크에 새로운 정책이 전달될 때 기존의 단순한 정책 선택을 벗어난 서로의 정책을 변환한 ACL을 최대한 순응시키는 메커니즘을 제안한다

The purpose of this study was to investigate the adaptation factor to North Korean refugees by identifying the relationship between character strengths affecting adaptation process and psychological well-being(PWB) in South Korea. The study examined the relationship between PWB and character strength of 117 participants and identified the sub-factors of character strength that affect the settlement period in South Korea. The data were analyzed by using the Model 1 of Process Macro and SPSS 22. The results of this study showed a correlation between PWB and sub-factors of character strength such as wisdom, humanity, courage, justice, temperance, and spirituality. The main effect was to investigate the relationship between PWB and sub-factors of character strength by independent variables. The level of PWB increased with the level of sub-factors of character strength. The moderate effect was showed in the courage of the settling period in relation to PWB. Finally, Limitations and implications of this study was discussed.

As the entrepreneurial ecosystem turns out to be a leading factor in improving nation's entrepreneurship, many studies are underway in the country to develop the start-up ecosystem. Although the entrepreneurial ecosystem is receiving attention as an essential factor for the nation's economic growth as well as entrepreneurship due to its inter-relationship with start-ups, government agencies and investors, criticism of measurement indicators has been increasing due to the different institutional and political contexts of each country, including the various definition of start-up ecosystem. In this study, we develop indicators that are suitable for domestic conditions in Korea and that can measure the level of start-up ecosystems in each regional level. FGI and Delphi surveys by scholarly experts in each field of start-ups & entrepreneurship were conducted to verify how well existing indicators fit the domestic situation and to develop indicators that can measure the local entrepreneurial ecosystem in Korea through close examination. As a result, the local entrepreneurial ecosystem consisted of three to four sub-components and 38 sub-components, each consisting of seven indicators, including Policy, Investment, Culture, Market, Human Capital, Support and Knowledge. It is expected that this research will be used to diagnose local start-up ecosystems and to propose discriminatory policies that can complement regional strengths and weaknesses.

As of March 2020, this study divided the applications for young children installed on Android-based smart-phones in Korea into top and bottom groups according to review scores, and selected 30 applications each, conducted content analysis and application evaluation, and looked at differences between groups. Through this, by providing objective information on the smart-phone application for young children, it is intended to help parents and early childhood education professionals select high-quality applications, and to present ideas and directions for developing applications suitable for development to application developers. As a result of application content analysis, only data presentation type, simulation type, and game type were found in all the top and bottom groups as for the application type. There was a difference in order. In the case of app purchase cost, the top group in the review score was evenly distributed from the low price to the high price of 100,000 won or more, while the bottom group had few high-priced applications. On the other hand, as a result of application evaluation, a significant difference was found in the entire evaluation score, including all functional elements and all content elements, between the top and bottom groups of the review score. In the case of detailed sub-factors, significant differences were shown in all factors except 'technicality' of functional elements.

The purpose of this study was to analyze the curriculum competencies of relationship-forming ability and practical problem-solving ability reflected in the activity tasks corresponding to the content elements of 'Love and marriage', 'Preparation for parenthood', 'Pregnancy and childbirth', 'Child care', and 'Family culture and intergenerational relationship' in the 2015 revised high school technology & home economics textbooks. The data are 330 activity tasks from 12 kinds of high school technology & home economics textbooks. The sub-factors of the relationship-forming ability were selected as Respect for Diversity, Consideration and Care, Family Relationship and Community Spirit, Empathy Ability, Conflict Management, and Communication, and the sub-factors of practical problem-solving ability were selected as Practical Reasoning, Decision Making, Value Judgment, Critical Thinking, and Executive Power. Based on the analysis criteria, the results of the two analyses and the expert review are as follows. First, regarding both the core concepts 'Development' and 'Relationship', the share of relationship-forming ability was relatively higher than practical problem-solving ability, and conflict management and executive power were the least reflected. For the core concept 'Development', Family Relationship and Community Spirit and Critical Thinking were the most reflected sub-factors, and for the core concept 'Relationship', Consideration and Care and critical thinking were the most reflected sub-factors. Second, in the case of the relationship-forming ability, the examples of activity tasks across sub-factors of each subject competency were devised to understand diverse opinions and sentiments and to develop competencies to care for each other and maintain healthy family relationships. In the case of practical problem-solving ability, the tasks allowed students to objectively analyze the socio-cultural background underlying the real-life problem, explore alternatives, and apply in their own lives.

The purpose of this study was to examine the effects of an application of the experimental practice which is one of the performance assessments on student's science achievement and affective domain in the middle school science For this study, two classes were chosen from a co-ed middle school in Gimhae, and assigned to the experimental and the control groups. Prior to the instructions, a science achievement test and a affective domain test were administered. After the instructions, post-tests which were similar to the pretests were also administered. The results showed that the performance assessment based on an experimental practice was more effective of enhancing students' science achievement. However, there was no significant difference in an affective domain test between the two groups. For the control group, there was a significant difference between the pretest and post test in affective domain. It means that there was a negative change in affective domain of the control group.
