As the utilization value of personal information increases, discussions on how to provide personal information are active, but information required by institutions to utilize personal information is being exposed more than necessary. Therefore, personal privacy protection is essential to overcome the problems and limitations of personal information protection. In this study, a decentralized identity information management model that overcomes the problems and limitations of the centralized identity management method of personal information and manages and selectively provides personal information by the information owner himself and demonstrates the excellence of personal information by implementing the Smart Personal Information Provision System (SPIPS) in the PBFT consensus algorithm through experiments.

인터넷의 급속한 발달과 이미지 콘텐츠 개발 기술의 발달로 현재 누구나 쉽게 이미지 콘텐츠의 공유 및 배급이 용이해졌다. 그러나 이로 인해 누드나 포르노와 같은 불건전한 유해 이미지들의 접근 역시 쉬워지고 있다. 특히, 스마트 폰이나 스마트 TV 등 멀티미디어 기능이 가능한 휴대장치 및 단말기의 비약적인 발전으로 인하여, 언제 어디서나 우리들은 유해 이미지의 노출되어 있다. 따라서 유해 이미지 시청이 적당하지 않은 연령층까지 무방비 상태에 놓여 있기 때문에 이를 막을 수 있는 시급한 대책이 요구되고 있다. 본 논문에서는 이중 피부 화소 검출에 이용하여 인체 영역 검출해내고 이것을 이용하여 유해 이미지 분류를 위한 방법을 제안하고자 한다. 일반적으로 피부 화소 검출 기법은 오차율을 가지고 있기 때문에 정확한 검출이 힘들다. 따라서 우리는 검출에 대한 강도를 조절하여 이중으로 피부 화소를 검출하여 좀더 정확한 피부 영역을 획득한다. 또한 기존의 방법들은 대체로 일차적인 피부 영역 검출에 초점을 둔 반면, 유해 판별의 주된 기준이 되는 가슴이나 성기, 엉덩이 등을 좀 더 중점적으로 찾으려 하지 않았다. 따라서 본 논문에서는 검출된 피부 영역에서 유해 부위를 좀 더 집중적으로 찾아 유해 판별 성능을 높이는 방법을 제안하고 실험으로 증명을 하고자 한다.

YouTube usage continues to increase, and the age group who spends the most time on YouTube is surveyed in the teens. It is practically impossible to prevent children and young people from being exposed to harmful content, so nurturing the ability to choose and use YouTube content in a healthy way can be a fundamental solution. Therefore, in this study, we tried to identify what YouTube literacy is for the digital native generation, and to prepare standards to be considered in common. The purpose of this study is to refine the definition of YouTube literacy competency and to develop a checklist that can be used when guiding and guiding children and adolescents to use the YouTube platform. To this end, a conceptual definition and checklist were developed by conducting prior research and overseas case analysis, and validity was secured through expert and educator reviews. The finally developed checklist includes 4 categories, 10 areas, and 23 criteria: media access, critical understanding, media participation, and ethical use.

This study was conducted as a case study to examine the characteristics and differences from the storytelling defined in the previous research through an analysis of the storytelling of brand campaigns appearing on the digital platform and to explore them. The results of the Seven Bridges brand campaign conducted by Busan City for eight months from September 2021 to May 2022 were as follows. First, storytelling that can be interpreted in various ways for individual users was conducted. Second, storytelling was composed of four stages based on social media marketing. Third, it was possible to establish a storytelling hierarchy that exposes the story in consideration of the marketing funnel. Through the case, it was possible to examine the recent brand campaign's storytelling as a framework that can be interpreted in various ways, focusing on social media.

In this study, in order to analyze physical changes that occur in real space in a survival game set in space and effectively apply this to the game, we investigated changes in the body exposed to a weightless environment based on literature on physical changes that occur in space. In addition, survival elements were derived by analyzing the system of survival games registered on the global platform STEAM. Based on the results obtained, a survival system was constructed so that it could be practically applied to a survival game set in space, and a method was designed to apply survival elements related to actual physical changes. Therefore, this study is expected to be used as a way to apply scientific facts as a survival factor for player characters when producing survival games set in space.

부모의 사회 활동 시간이 늘어남에 따라 아이들이 혼자 집에서 보내는 시간도 늘어나고 있다. 따라서 아이들의 자립심을 크게 제한하지 않으면서 노출되기 쉬운 실내 위험으로부터 아이들을 보호하고 아이의 심리, 감정적 상태에 따라 적절한 지도를 해주는 도움이 필요하다. 본 연구에서는 RFID 기술을 기반으로 아이들을 물리적 위험으로부터 보호하고 자연언어처리 기술을 이용하여 아이의 심리, 감정 상태에 따른 음악과 애니메이션의 멀티미디어 콘텐츠를 제공한다. 또한 지속적인 관심이 필요한 일정 관리, 일상 생활에서 도움을 주는 전자제품 사용법 안내 등의 정보를 제공하여 아이 스스로 자신의 일을 할 수 있도록 도움을 준다. 본 연구에서는 가상의 가정을 디자인하여 실현 가능한 시나리오를 중심으로 이와 같은 서비스를 시뮬레이션 한 결과를 보인다.

SAR(Specific Absorption Rate: 전자파 흡수율)이란 생체조직이 단위 질량당 흡수하는 전력(W/kg)으로 ICNIRP(International Commission on Non-ionizing Radiation Protection: 국제비전리방사위원회)국제 규격에서는 10 g평균 첨두 SAR 값을 인체 전신 및 국부(두부 및 몸통)에 대해 각각 0.08 W/kg과 2 W/kg으로 규정하고 있고, 미국의 FCC 규격에서는 국부노출의 경우 1 g 평균 첨두 SAR 값을 1.6 W/kg 값으로 제한하고 있다.

The purpose of this study is to examine the effect of media on plastic surgery experiment. Firstly this study try to find the relationship between exposure to media and other intervening factors(e.g., body image, self-esteem, fashion attitude). The data collected for this study was gathered through questionnaire survey with 443 female students in Seoul. The results are as follows: Using ANOVA, we found that those prefer the magazine over TV or Internet had positive body image, higher self-esteem, and positive fashion attitude(e.g., personality/self-expression, fashion leadership, sexual attraction). Using regression analysis, we found that the we found that the factors influence plastic surgery behavior are the exposure to magazine and the factors influence plastic surgery planning are the clothing attitude (especially fashion leading power, sexual attraction).
