This study is conducted to confirm a correlation between psychological health and self-rated oral health on. 3,591 people aged from 19 to 55 were studied through the Korean National Health and Nutrition Survey. Self-rated oral health risk in relation to psychological health and 95% confidence interval are calculated through multi-variate regression analysis, and the results were as in the following. Self-rated oral health OR was the most when subjects had felt stressed. Toothache experience, OR was the most when subjects had suffered depression more than 2-weeks straight. In terms of mastication problem, OR was the most when subjects had had psychological consultation experience. In terms of TMJ symptom experience, OR was the most when subjects had suffered depression more than 2-weeks straight. In terms of talk problem, OR level was particularly high when subjects had had psychological consultation experience. Therefore, daily stress, depressed conditions, and psychological consultation experience have a correlation with self-rated oral health. developing a oral health promotion program considering psychological health would help those two domains.

The purpose of this study was to investigate factors affecting perceived oral health status according to socioeconomic status and community periodontal index(CPI) and decayed, missing, and filled teeth(DMFT) using the 6th Korean national health and nutritional examination survey(KNHANES VI) and provide a basic data for plan of policy. The higher the age, the lower the household income and education level, the worse the subjective oral health had better oral health and there was a tendency that the respondents who had no oral exam within 1 year and experienced CPI or DMFT estimated their own health as worse. It is needed to make policy development to resolve the inequality of oral health.

The purpose of this study was to identify the influencing factors of Korean adolescents' consumption of convenience foods based on a bio-psycho-social model. Data were obtained from the 15th (2019) Korea Youth Risk Behavior Survey, which involved a nationwide representative sample of 57,303 middle- and high-school students. As a result of the study, gender, grade, and atopic dermatitis were biological factors of convenience food intake in adolescents. The psychological factors were perceived stress level, experience of depression, suicidal ideation, subjective sleep sufficiency, perceived health status, physical activity, and current smoking and drinking. And nutrition and meal education, breakfast frequency, subjective academic achievement, subjective economic status, and family living together were sociological factors that affected adolescents' convenience food intake experience. Therefore, it is necessary to provide effective nutrition education programs and provide emotional support to manage healthy eating habits of adolescents. In addition, family members of adolescents should be included in education.

현재 구미에서 터널의 설계에는 RMR, Q와 같은 암반분류 기법과 경계요소 해석법과 같은 간략한 탄성 프로그램에 경험적 파괴조건식을 적용하여 이완대를 계산하고 터널의 지보량을 추정하는 방식이 널리 적용되고 있다. RMR이나 Q와 같은 암반분류법은 지하공동의 안정성에 영향을 미치는 중요한 지질 요인들에 근거하여 암반을 몇가지 등급으로 분류하고 지보방법을 결정하는 분류 방식으로 가장 많이 사용되고 있으나 각 항목의 평가방식이 경험적인 판단을 요하게 되어 주관적인 오류에 빠질 가능성이 많고, 또 여러 가지 대체 수단이 있어 종합적인 판단을 얻기가 용이하지가 않다.

흥미는 학습을 비롯한 여러 인지 과제 수행에 있어서 중요한 변인이 된다. 그러나 그 개념의 모호성이나 측정 가능성에 대한 문제 등으로 인해서 이에 대한 직접적인 연구가 부족한 것이 현실이다. 본 연구에서는 컴퓨터 게임의 상황에서 발생하는 흥미와 관련된 변인으로서 주관적 시간 지각과 flow 경험에 대한 설문을 통해서 흥미관련요인을 알아보고자 하였다. 게임에서의 흥미의 경험이 실제 시간보다 짧은 주관적 시간 지각의 왜곡으로 나타날 것이며 flow와 관계된 요인들이 결국 흥미 유발에 유의한 관련성이 있을 것이라고 기대되었다. 결과에 따르면 주관적 시간 지각이 흥미의 정도에 따라 차이가 있는 것으로 나타났으며, 도전감, 주의, 시간 왜곡감, 기술, 각성 등의 변인도 흥미와 관련된 것으로 나타났다. 또한 네트웍과 개인 조건에 따른 흥미와 시간의 왜곡감, 전략, 시간 지각의 차이도 역시 유의하였다.

본 논문은 병리진단지식을 활용한 조직세포 영상의 암진단을 위한 온톨로지 기반의 진단 프레임워크를 제안한다. 병리진단 분야는 환자로부터 획득한 조직셈플을 전자현미경을 이용하여 조직의 구조적 특징과 형태학적특징을 기반으로 진단을 한다. 이러한 형태의 진단은 의사의 주관적인 경험에 많이 의존하기 때문에 같은 병증에 대해서도 의사들마다 다른 진단을 하게 된다. 최근 이러한 주관적인 경험에 의한 오진을 줄이고자 주어진 조직세포 영상의 형태학적 특징들의 정량적인 수치들을 이용하는 컴퓨터 보조진단(CAD)시스템들이 많이 이용되고 있다. 그러나 이러한 진단 시스템의 요소기법들은 하나의 병증만을 진단하는데 활용되기 때문에 구성기술의 재사용성은 매우 떨어진다. 따라서 본 논문은 요소기술들의 재활용성을 높이고, 객관화된 병리진단을 위한 온톨로지 기반의 진단 프레임워크를 제시한다.

The purpose of this study was to help improve oral health care planning for the elderly in an effort to promote the oral health of elderly people in preparation for aging society. The subjects in this study were 200 elderly people who were selected by random sampling from senior centers in Seoul. An interview was conducted to gather data from June to September 2008, and the data collected were analyzed.: 1. The mean number of residual tooth was 13.71. 2. Concerning connections between gender and subjective oral symptoms, gender had a statistically significant relationship to temporomandibular joint dysfunction(p=0.000), dry mouth(p=0.001) and halitosis(p=0.006). The men underwent more oral symptoms than the women. 3. As for the relationship of mastication(p=0.000), oral pain(p=0.010), temporomandibular joint dysfunction(p=0.010) and dry mouth(p=0.001) to subjective oral health state, the elderly people who were not in a good oral health suffered more oral symptoms, and the gap between them and the others was statistically significant. 4. A larger number of tooth led to less mastication difficulties, less dry mouth and more gingival diseases, and the relationship between the factors was statistically significant. A better oral health state led to less mastication difficulties, less oral pain, less dry mouth and less bad breath, and the relationship between the factors was statistically significant. Through this study the oral health the elderly people perceive wss concerned with oral symptom, and the number of residual teeth also had links to subjective oral symptoms. Therefore, to maintain original teeth of the elderly people, the management system of oral health and the education program for oral health in order to prevent disease relateded with oral and enhance the perception standard of oral state are indispensably necessary to the elderly people.

The purpose of this study is to explore the relationships between high-tech employees' job rotation experience characteristics, perception of job rotation, and subjective career success. It also aims to examine the mediating processes through which high-tech employees' job rotation experience characteristics contribute to employees' subjective career success. The results from hierarchical multiple regression analysis revealed that high-tech employees showed higher subjective career satisfaction when they were transferred to another job voluntarily, and the frequent job rotations have an adverse effect on employees' career satisfaction. It also turned out that employees' perception of job rotation fully mediated the relationship between job rotation experience characteristic and subjective career success. Finally, implications, limitations, and research recommendations are discussed.

For the past half century, researches on human psychology have witnessed the flourish of various research tools in this area. Many psychological measures were developed to get objectified data and this trend has lead to the abundance of quantified results. However, considering subjectiveness and refinements of human experience, the research focused on individual's unique perspectives and explanations is needed also. In this vein, this study proposed the usefulness of photography as a research tool for human psychology. With the wide spread of smart phone, taking photo became the everyday activity for modern people and also a part of a public art. If photo could play an efficient and unique role to study human psychology, the depth and width of human understanding might change dramatically in positive way. Two friendship photos were presented to suggest the possibility of photo as a research tool and final considerations of using photo were suggested briefly.

Smoking among adolescents is a major public health problem. This study was performed to determine the association between cigarette smoking and depression Symptoms of high school students. Data were drawn from the Korea Youth Risk Behavior Web-based Survey 2009. Subjects were 36,657 high school students living in the community. Adjusting for covariates (sex, school year, school education, economics, school record, hours of sleep per day, self-reported stress, self reported happiness, self-reported health status, suicidal thinking), smoker(OR=1.43, 95% CI: 1.35-1.50), 10~19 cigarettes per day(OR=1.48, 95% CI: 1.22-1.79) and more than 20 cigarettes per day(OR=2.05, 95% CI: 1.59-2.64) were independent risk factors for depression Symptoms. It was found that cigarette smoking is a independent factor related to adolescent depression. Adolescent smoking cessation is needed to management of adolescent depression.
