Objectives: The purpose of this study was to examine the oral health care and educational needs of college students in an effort to give some suggestions on the development of oral health educational media. It`s basically meant to boost the efficiency of oral health education geared toward college students. Methods: The subjects in this study were 500 students at seven different colleges located in Daejeon and South Choongcheong Province. After a survey was conducted, frequency analysis and ANOVA were utilized to analyze the collected data. And the records of the in-depth interviews of 10 students were analyzed as well. Results: The gender of the students and whether their major was linked to health or not made differences to their knowledge of dental caries. And there was nothing to affect their knowledge of periodontal diseases except whether their major was related to health or not. They didn`t have a good knowledge of periodontal diseases, and they just regarded toothbrushing as a means to prevent dental caries and periodontal diseases. They preferred to acquire knowledge over the Internet. Conclusions: College students who don`t know well about periodontal diseases should be given an opportunity to learn about periodontal diseases and diverse ways of preventing dental caries and periodontal diseases other than toothbrushing. As the college students preferred to surf the Internet, educational programs should be developed in the form of video clips that can be found over the Internet, and more aggressive publicity is required via SNS, etc.

임지환,나관우,우재민,서화정,Lim, Ji-hwan,Na, Gwan-Woo,Woo, Jae-Min,Seo, Hwa-joeng 한국정보통신학회 2018 한국정보통신학회논문지 Vol.22 No.5
형태 보존 암호는 암호화하고자 하는 목적 정보에 대한 변형 없이 형태를 유지한 상태로 암호화하는 기법으로써 최근에 국가보안기술연구소에 의해 제안되었다. 본 논문에서는 형태 보존 암호를 활용하여 기존의 사이버 보안 관련 문제를 해결하는 방안을 제안하고자 한다. 먼저 랜섬웨어 공격을 효과적으로 방어하기 위해 시그니처 및 확장자를 형태보존암호로 암호화하는 방안을 제시한다. 해당 기법은 최소한의 정보를 암호화함으로써 랜섬웨어에 대한 노출을 최소화할 수 있다. 두 번째로 스테가노그래피와 같이 비밀 정보를 숨기는 기술상에서도 해당 정보의 양을 최소화함으로써 공격에 대비할 수 있는 방안을 제시한다. 마지막으로 형태보존암호와 경량암호에서 암호화에 따른 동작 속도를 비교하고, 형태보존암호를 최적화하였을 때, 그에 따른 성능 향상까지 비교하고자 한다. Recently, Format-Preserving-Encryption (FEA) was suggested by the National Security Research institute (NSR) as an encryption method while maintaining the format without a distortion to the intended information to be encrypted. In this paper, we propose a scheme to solve conventional cyber security problems by using FEA scheme. First, we present the method to encrypt signatures and extensions with FEA in order to effectively defend against Ransomeware attacks. This technique can mitigate the exposure to the Ransomeware by encrypting the minimum information. Second, in order to reduce the secret information for Steganography, we introduce a new way to minimize the secret information with FEA. Finally, we compare the operation speed by encryption with FEA and Lightweight Encryption Algorithm (LEA), furthermore when we optimize FEA we want to compare with the performance improvement accompanying with it.

The purpose of this case study is to research the positive psychological impacts on a mother’s self-esteem and parenting stress with developmental disabilities for art therapy. The subject of study is a mother with a child with disabilities who lives in Tokyo. 20 tests were implemented twice a week for 50 minutes from September 2019 to November 2019. Two fields for the test have been set up to measure the mother’s degree of self-esteem and the stress of bringing up her disabled children. The results have led to a comparative analysis between the initial and post-test implementation. The mother’s prior and post tests were conducted through the methods of KHTP and PITR in order to carefully analyze the changes, according to the results. For each period’s progress, a periodical observation test was used to analyze this case study in order to observe the process of their changes and actions based on their self-esteem and parenting stress. The results of this study are as follows: First, art therapy of positive psychology has been confirmed to have a positive impact for the mother according to the measurement of their self-esteem and KHTP. Second, art therapy through positive psychology is able to confirm a positive influence for parenting stress when nurturing a child with developmental disabilities through scaling nurtural stress and PITR. Third, this art therapy of positive psychology also confirms a positive impact for mothers to improve their self-esteem and nurtural stress by the periodical observation test. This study case shows that positive psychological art therapy can enable a positive impact for parenting stress and mother’s self-esteem.

The purpose of this study was to provide basic information need to promote early childhood's growth with balanced diet and preferable dietary attitude by observing the provision of food service management in kindergarten in Daejeon. We researched the dietary life of full- and half-day program children and their mothers. A questionnaire survey was conducted with 392 children attending kindergarten and their mothers. The questionnaire items examined general characteristics, dietary life, dietary behavior, frequency food intake etc. The results of the survey were as follows. The frequency of breakfast intake of the half-day program children and their mothers was higher than that of the full-day program children and their mothers. Most of the children had an unbalanced diet about soybean, kimchi, and vegetables, whereas their mothers had an unbalanced diet about processed food In general, the half-day program children showed higher scores than full-day children for the items of the dietary behavior of kindergarten. The dietary attitude and nutrition attitude scores of the half-day program children and their mothers were higher than those of the full-day program children and their mothers.

This study focuses on the importance of non-face-to-face healthcare, based on the experience with the COVID-19 pandemic, and proposes a model for oral health management services utilizing personal data, known as “my data.” The model aims to develop a comprehensive system that collects and integrates individual health records for easy access. It includes assessing oral health through oral examination records and surveys, creating risk assessment algorithms tailored to various population groups, and standardizing medical terms and data. The goal is to accurately evaluate individual oral health conditions and provide personalized services. However, the success of the model requires considerations such as platform management, user experience enhancement, and medical data security. The research proposes possibilities for further investigation to enhance the oral health service model. This study introduces a novel approach to individual health management, establishing the foundation of effective health management even in non-face-to-face settings.

A key component in tissue engineering for bone regeneration is the scaffold that serves as a template for cell interaction and the formation of bone-extracellular matrix to provide structural support to the newly formed tissue. In this study, poly(L-Lactide-co-glicolide)(PLGA) scaffolds were prepared by solvent casting/salt-leaching, ice particle-leaching and gas-forming/salt-leaching. Cellular viability and proliferation were assayed by 3-(4,5-dimethylthiazole- 2-yl)-2,5-diphenyltetrazolium-bromide(MTT) test. Osteogenic differential cells were analyzed by ALP activity. Through RT-PCR analysis, we observed ALP and osteocalcin m RNA expression. Scaffold with BMSCs were implanted into the back of athymic nude mouse to observe in vivo behavior. Thin section were cut from paraffin embedded tissues and histological sections were stained by trichrome, immunohistochemical, von kossa staining. The cell proliferation and ALP activity of BMSCs in the scafoolds was the highest in the scaffolds using solvent casting/salt-leaching method. In RT-PCR results, in the all type of scaffolds observed specific gene expression of ALP, osteocalcin. By histological staining, we could observed collagen and calcification region in scaffolds by solvent casting/salt leaching method. Thus Solvent casting/salt-leaching method provided highly porous structure with good interconnections between each pores, which can support the surface of cell proliferation, differentiation. This result indicates that solvent casting/salt-leaching is useful for osteogenesis of BMSCs.
