This study investigated the level of knowledge about changes in the oral environment according to the presence or absence of smoking in adults in their 20s and 40s. It was conducted to use as basic data for the relationship between periodontal disease and smoking and the importance of concurrent education on smoking cessation during oral health education for adults.In subjective oral condition analysis, 65.4% of non-smokers and 59.0% of smokers thought that it was very good or good. Also, in both the non-smokers and smokers groups, the most common answer was that they thought the cleanliness of non-smokers would be higher. To the question of whether they had ever received anti-smoking education, 63.9% of non-smokers and 76.1% of smokers answered 'yes'. In the education that 'the oral environment changes depending on whether or not there is smoking', the non-smoker group showed 'no' and the smoker group showed 'yes' respectively. As a result, oral health education related to smoking and prevention It is thought that specific and active educational methods should be accompanied for this.

Our society is rapidly changing, and there is a growing demand for various convenience services in our daily lives. Among these services, railway and subway stations require tailored wayfinding services to accommodate individuals with disabilities. Currently, signage and information desks are the primary means of navigation. However, individuals with disabilities often rely on assistance from others due to physical discomfort or cognitive impairments. In this paper, we propose a customized wayfinding system within railway stations to assist individuals with disabilities. This system aims to ensure safe and convenient mobility in complex indoor environments, including transfer facilities.

Recently, NAND flash memories have replaced magnetic disks due to non-volatility, high capacity and high resistance, in various computer systems but it has disadvantages which are the limited lifespan and imbalanced operation latency. Therefore, many page replacement policies have been studied to overcome the disadvantages of NAND flash memories. Although it is clear that these policies reflect execution characteristics of various environments and applications, researches on the foundation-policy decision for disk buffer management are insufficient. Thus, in this paper, we propose a foundation-policy recommendation model, called FRM for effectively utilizing NAND flash memories. FRM proposes a suitable page replacement policy by classifying and analyzing characteristics of workloads through machine learning. As an implementation case, we introduce FRM with a disk buffer management policy and in experiment results, prediction accuracy and weighted average of FRM shows 92.85% and 88.97%, by training dataset and validation dataset for foundation disk buffer management policy, respectively.

With the expansion of the indoor service-providing robot market and the electrification of automobiles, research on autonomous driving is being actively conducted. In general, in the case of outside, the location is mainly recognized through GPS, and location positioning is performed indoors using technologies such as WiFi, UWB (Ultra-Wide Band), VLP, LiDAR, and Vision. In this paper, we introduce a system for location-positioning using LED lights with different color temperatures in an indoor environment. After installing LED lights in a simulated environment such as a tunnel, it was shown that information about the current location can be obtained through the analysis of chromaticity values according to location. Through this, it is expected to be able to obtain information about the location of the vehicle in the tunnel and the movement of the device in a room such as a warehouse or a factory.

Nowadays, Light railway system is attracted public attention as solution for metropolitan traffic congestion. But it is difficult to decide an appropriate light railway system. It is especially hard in the Seoul metropolitan to decide an appropriate system, because there are many factors that must considered. So we research application status of light railway system that is scheduled or promoted in the Korea and the foreign nations. And we selected systems by types of city. In this paper, we divided into 6 types of city through factor analysis and cluster. And we considered various factor such as technology, transportation, environment etc that used previous research and feasibility study. To determine the priority among the factors, AHP(Analytic Hierarchy Process) was applied as a method for multi-standard decision method.

The purpose of this study is to examine the arguments about the conceptualization and the assessment of mental capacity and legal competence concerning the adult guardianship. Based on these literature reviews, the author analysed Mental Capacity Act 2005 of United Kingdom. The act conceptualizes legal competence as a concept dependent on a specific decision, time, and environmental support or convenience. According to the act, the assessment of the legal competence shall be made with ensuring the person all the viable supports and environmental conveniences. And it appears that the hierarchical assessment system of the act assures that the more the decision is important the more professional and more formal assessment shall be used. Based on these findings the author suggested several implications for the legislation of a new adult guardianship act in Korea.

통계청의 '인구주택총조사' 결과(2019년 11월 1일)를 기준으로 발표한 '2019 지방자치단체 외국인 주민 현황'을 보면, 국내 체류 외국인은 2,216,612명으로 지난해인 2018년 2,054,621명에 비해 161,991명(7.9%) 증가했다. 이러한 결과는 우리나라 전체 인구(51,850,705명) 중 4.3%에 해당하며, 외국인 주민 최초 조사 연도인 2006년 536,627명과 비교했을 때 4배 이상 증가한 것을 확인할 수 있다. 국내 이민자들의 수가 증가함에 따라, 우리가 생각해야 할 점은 그동안 다문화 관련 정책적 환경이 급변하였을 뿐 아니라, 환경적 변화에 맞게 정책의 변화도 지속해서 이루어졌다는 것이다. 또한, 다문화가족의 양적 증가뿐 아니라, 거주 기간도 장기화되면서 초기 적응이라는 정책보다 구체적이고 포괄적인 새로운 정책 요구를 파악할 필요성이 대두되고 있다. 따라서 다문화가정 결혼이주여성들의 창업 의지에 미치는 요인들을 연구하는 것은 향후 다양한 다문화 정책 수립 및 창업, 경제활동 활성화에 있어 큰 의미가 있다. 다문화가정 결혼이주여성에 대한 창업 의지에 영향을 주는 요인에 관한 연구는 학문적으로 중요한 의미를 갖는데, 선행연구는 주로 북한이탈주민 및 다문화 이민자의 문화지능 또는 사회체제 등이 창업 의지에 영향을 미치는지 초점을 두어왔다. 본 연구의 목적은 다문화 이주민의 창업 의지에 관한 기존 선행연구들을 바탕으로 다문화가정 결혼이주여성들의 창업 의지에 영향을 미치는 요인을 실증분석해 보는 데 있는데, 해당 요인들을 파악함으로써 앞으로 다문화가정 결혼이주여성들의 창업 활성화를 위한 정부와 대학의 역할을 논의해 보고자 한다. 다문화가정 결혼이주여성들의 창업 의지에 영향을 미치는 영향은 개인적 특성(기업가정신)인 '진취성', '혁신성', '위험감수성', '기회 인식'과 긍정심리자본 특성인 '자기효능감', '희망', '회복력', '낙관주의' 등을 선정하였다. 해당 요인들을 바탕으로 수도권에 거주 중인 다문화가정 결혼이주여성들에게 설문조사를 진행하였으며, 설문조사 결과로 신뢰성 분석과 요인분석, 다중회귀 분석, 상관관계 분석 등을 통하여 본 연구에서 설계한 가설들을 검증해 보고자 한다.

So far, the rationality of management decisions has been limited to the economic rationality of maximizing self-interest. However, management rationality in the ESG era, which pursues the interests of the environment, society, and the company from the perspective of harmony and balance, requires new judgment standards. The goal of ESG management is sustainable development. Sustainable development goes beyond the accumulation of wealth, which was the goal of the past economy, and aims for the happiness of the entire society, including coexistence and fair development that develops together with the entire society. From Aristotle's perspective, the happiness of the entire society promoted by sustainable development is no different from the highest good of citizens, members of the community. Accordingly, this paper attempted to explore the new management rationality required for managers in the ESG era by comparing Aristotle's concept of citizenship with the concept of 'corporate citizenship', one of the main concepts of ESG management. Through this, we sought to show that companies are essentially communal entities and that the company's pursuit of profit requires rationality of balance and harmony with environmental and social interests.
