흔히, 건강과 스트레스, 사회가 건강에 미치는 영향, 식생활의 변화와 건강 등에 관한 얘기를 할 때 그 촛점은 40대에서 50대의 성인에 맞추어 지게 된다. 그렇다면 그 이전엔 과연 이러한 영향을 받지 않을까? 확실히 그렇지 않다. 신체적으로나 생각들이 한창 자라는 나이인 어린이들. 당장 눈에 보이는 것은 아니라 하더라도 이들은 누구보다도 그런 변화에 민감하게 반응한다. 따라서 어린이를 정말로 건강하게 키우려면, 이제는 잘 짜여진 식단이나 따뜻한 방안에서 키울것이 아니라 한차원 높여, 올바른 성격을 형성하고 올바르게 사회를 인식할 수 있는 능력을 키울 수 있는 분위기를 만들어주어야 하겠다.

사람의 눈은 카메라와 흡사한 구조와 원리를 가지고 있어서 빛을 직접 받는 경우 조리개가 오므라지게 되어 오히려 피사체를 인식하는 데 어려움을 겪는다. 그 이유는 광원과 피사체 간의 조도(밝기) 차이로 설명할 수 있다. 사람의 동공은 눈으로 들어오는 빛의 밝기에 따라 커지고 작아진다. 따라서 광원이 너무 밝은 경우에는 상대적으로 피사체에서 반사된 빛이 안구로 적게 들어와 피사체가 오히려 어두워 보이는 결과를 초래한다. 대부분의 사람들은 이 같은 사실을 간과한채, 조명은 무조건 밝아야 한다고 믿어 왔으며, 그 결과 우리가 속한 모든 건물들은 직접조명 일색이다. 선진국에서는 이미 조명이 인체에 미치는 영향에 관한 연구가 지속적으로 발전함에 따라 이미 오래전부터 간접조명 방식이 채택됐다. 간접조명의 효과는 영역을 넘어서서 건강한 실내 공간을 조성하는 필수적인 요소로 자리매김하고 있다. 이제 현대인들은 눈에 피로감을 주는 노출형 조명보다는 점차 눈을 편하게 해서 몸과 정신의 피로를 릴렉스 시켜주는 간접조명방식으로 나아가야 할 것이다.

Safety accidents and industrial accidents are constantly occurring in existing industrial sites. In addition, the probability of accidents occurring due to physical and mental fatigue of workers is increasing. Accordingly, it is required to introduce systematic management and various systems for the safety of workers. In this paper, by developing an access control system using bio-metric information at industrial sites, we develop efficient health management and access control management functions for workers. Workers are identified through face recognition for access control, and health status is determined through iris recognition. It aims to improve accuracy and develop a more efficient management system by diagnosing signs of health abnormalities through the congestion of the iris and eyes of workers. Finally, the contents of the development consist of an on-site access control system, an access control program for administrators, and a main server system that diagnoses signs of abnormal health of users.

Subjects of the research were 668 elderly people aged over 65 from Gangneung city. OHIP 14 went through a first translation from English to Korean, discussion among experts, a second translation from Korean to English, and then the translation was approved. After the primary and main research were carried out, validity and correlation coefficient with the outcome of oral and mental health examination were studied. OHIP 14 in terms of the perception of oral health was relevant to the perception of overall health and oral health, the necessity of dental treatment, the satisfaction about oral health, the level of pain from observation, and the satisfaction about artificial tooth. OHIP 14 on account of oral health state was related to the number of present natural teeth, the necessity of dental treatment, and the status of no teeth. OHIP 14 according to overall health was correlated to the number of ailments, the state of mind, nerve systems, bones and sinews, digestive systems, urogenital systems, cerebrovascular systems, respiratory systems, eyes, ears, and dementia. OHIP 14 according to the perception of oral health showed a significant difference in the perception of overall health and oral health, the level of pain in terms of observation, and the satisfaction on artificial tooth. OHIP 14 on account of oral health state demonstrated a meaningful difference in the number of present natural teeth, the necessity of dental treatment, and status of no teeth. OHIP 14 in terms of overall health exhibited considerable difference in the state of mind, nerve systems, bones and sinews, digestive systems, cerebrovascular systems, respiratory systems, ears, and dementia. From the study, it was proven that there was relevance between the validity of OHIP 14 and the perception of oral health, the state of oral health, and the state of overall health in the experiment on some Korean elderly people.

This study was designed to investigate the current state of lens wearing and care, and to investigate eye discomfort according to the care method. Data of 209 female college students wearing lenses for more than 1 year were analyzed using the SPSS / WIN 22.0 program. 40.2% of female students wear lenses every day and 97.1% wear all day. However, only 45.4% of students washed it daily, and only 17.7 % used protein remover during wash, which resulted in poor management. 98.1% of students complained of discomfort due to the lens, and the Ocular Surface Index (OSDI) scored 42.88 ± 15.25, which was classified as a severe dry eye and threatened eye health. Therefore, it is necessary to improve students' awareness of lens management, and periodical lens inspection and management education are needed.

This study aimed to explore the experiences of community child center workers about how they have dealt with the mental health of children and adolescents who use such centers. For this study, we used a sample of ten community child center workers, who were divided into two groups and who participated in four focus group interviews. The results revealed four themes and twelve sub-themes: "the reality of facing children's mental health issues," "dealing with children's mental health issues and limitations," "know-hows accumulated from experiences and visible changes," and "remaining tasks--the workers who cannot give all." Based on the results the implications of promoting the mental health of children at community child centers were discussed.

The aim of this study was to analyze factors related to xerostomia in adults aged 30 years and over. The data were analyzed using the t-test, one-way ANOVA and multiple linear regression analysis in the SPSS version 12.0 program. The results were as follow. 1. The respondents who were older than 51 years old, unemployed and had less than 3 million won of average monthly income were more aware of xerostomia (p<0.05). 2. The respondents who answered poor and moderate for their general and oral health and the group with duplicate medication and comorbidity were more aware of xerostomia (p<0.05). 3. The respondents that had problems in chewing, communication, ordinary activities and complained of pain discomfort and suffered from anxiety depression were more aware of xerostomia (p<0.001). 4. The respondents that answered frequent dryness on their skin, eyes, lips, and nasal mucosa were more aware of xerostomia (p<0.001). 5. Xerostomia showed highest correlation with quality of life ($\beta$=0.436) followed by the number of medications ($\beta$=0.239), sense of entire body dryness ($\beta$=0.200), feeling of hopelessness ($\beta$=0.160) and number of oral mucosa disease symptoms ($\beta$=0.099) (p<0.05). According to the results of the study, xerostomia may cause deterioration in quality of life. Thus, it is advised to improve the patient management system among dental professions to prevent various complications caused by xerostomia and conduct regular health education on the cause and management method of xerostomia.

The controversy of the risk perception related to particulate matters becomes significant. Therefore, in order to understand the nature of the particulate matters, we gathered articles and comments in on-line community related to bicycling which is affected by exposure of the particulate matters. As a result, firstly, the government - led particulate matter policy was strengthened and segmented every period, butthe risk perception related to particulate matters in the bicycle community has become active and serious. Second, as a result of analyzing the perception change of outdoor activities related to particulate matters, bicycle users in community showed a tendency of outdoor activity depending on the degree of particulate matters ratherthan the weather. In addition, the level of the risk perception related to particulate matters has been moved from fears of serious threat in daily life and health, combined with the disregard of domestic particulate matter levels or mask performance. Ultimately, these risk perception related to particulate matters have led some of the bicycling that were mainly enjoyed outdoors to the indoor space. However, in comparison with outdoor bicycling enjoyed by various factors such as scenery, people, and weather, the monotonous indoor bicycling was converted into another type of indoor exercise such as fitness and yoga. In summary, it was derived from mistrust of excessive information or policy provided by the government or local governments. It is considered that environmental policy should be implemented after discussion of risk communication that can reduce the gap between public anxiety and concern so as to cope with the risk perception related to particulate matters. Therefore,this study should be provided as an academic basis for the effective communication direction when decision makers establish the policy related to particulate matters.
