Poor oral hygiene can cause severe periodontal disease. Therefore, it is necessary to educate individuals regarding the importance of maintaining good oral hygiene. To this end, in this study, we evaluated the efficacy of using a phase contrast microscope as an instructional tool for oral hygiene. Forty patients, randomly divided into test and control groups, were recruited 6 months after receiving oral prophylaxis. A phase control microscope was used as a demonstration tool for the test group, and a dentiform model was used to demonstrate the ideal tooth-brushing method for the control group. In the test group, awareness regarding the importance of proper oral hygiene was found to increase by 30%, and in the control group, awareness was increased by 20%. The overall satisfaction with the instructional program was 80% in the test and 70% in the control group. The level of understanding was 99% in the test and 80% in the control group. Instructions were easily followed by 80% of the test and 60% of the control group. Understanding of the program was significantly higher in the test group than in the control group (p < 0.05). The overall satisfaction and understanding of proper oral hygiene was over 70% for both the groups. The phase contrast microscope-based instructional program yielded higher actual practice rates. The phase contrast microscope is desirable tool for motivating patients and spreading awareness regarding the importance of maintaining good oral hygiene.
본 연구는 전문가집단을 대상으로 식품안전사고 발생 시 ‘보도용어’와 ‘대응용어’에 대한 인식도 차이를 알아보고 용어선택에 따른 피해정도를 개선하기 위한 기초자료를 제공하고자 실시하였다. 식품기업체 식품안전관리책임자 28인과 식품전문기자 17인 총 45인을 대상으로 인식도 조사 및 개선방안에 대해 설문조사하여 통계분석 하였다. 그 결과, 식품안전사건 발생 시 미디어의 영향이 크다는 질문에 기자 70.6%, 기업체 92.9%가 ‘매우 그렇다’의 응답률을 보였다. 미디어의 자극적인 용어사용이 기업피해의 원인이라는 인식에는 기업체의 83%가 ‘매우 그렇다’, 기자의 70.6%가 ‘그렇다’로 답해 양측 모두 자극적 용어사용으로 인한 기업피해를 인식하고 있었다. 미디어의 ‘보도 용어’와 정부, 학계 등의 ‘대응용어’가 소비자의 인식과 사건의 파급에 차이를 주는지를 묻는 질문에 기업체의 92.9% 와 기자의 35.3%가 ‘매우 그렇다’로 답해 두 집단 모두 용어의 차이가 소비자의 인식뿐 아니라 파급을 확대시킨다는데 공통적인 의견을 보였으나 기업이 훨씬 심각하게 느끼고 있었다. ‘보도용어’의 통일 및 사용제한에 대해 기 업체는 전반적으로 긍정적인 입장이고 기자는 긍정과 부정으로 답변이 나뉘어 개인차가 컸다. 식품안전사건 발생 시 소비자와 기업체의 피해를 줄이기 위해 기업과 기자, 전문가간 사용하는 용어의 일치 및 차이를 좁힐 수 있는 방안 마련이 필요하다고 사료된다.

This study is based on parents that have preschool children of age 4~5, and analyzes the perception and parent education demand through parent experience of fire. As a result of the study about perception through parent experience about safety life, safety accidents, safety education of fire, the effect of parents' safety consciousness to fire safety life turned out to be moderate for fathers and large for mothers. The safety education method was mostly done in speaking than experience for fathers, while mothers did education through experience in daily life. Also the difficulties in safety education was lack of educating time for fathers while it was lack of knowledge and methods for mothers. Perception through parent experience of fire safety accidents showed that fathers did not have experience of fire safety accidents while mothers did. The locations perceived by parents where fires mostly occurred showed to be within home for both parents, and both administered first aid in managing fires. Perception through parent experience of fire safety education showed the importance of fire safety education to be important in both parents, and both parents had no experience in fire safety education. Also the fire safety education knowledge acquisition method was TV or the Internet for fathers, while it was participating in seminars or lectures for mothers. Fathers were moderately satisfied of the fire safety education instruction of childhood education centers, while mothers were slightly dissatisfied. For the demand of parent education about fire safety education, fathers were moderate while mothers thought it necessary of parent education necessity. The reason why parent education was needed was to be able to know immediate and prompt measures and first aid treatment in emergency situations for fathers, while it was to figure out the cause of fire safety accidents and prevent it beforehand for mothers. For the education institution of fire safety education, fathers demanded it for safety related institutions while mothers demanded it for children education institutions, and the number of times for parent education was once or twice a year for fathers while it was once a month for mothers. For the parent education instructor of fire safety education, fathers demanded safety education experts while mothers demanded infant teachers that completed the safety education course. For the fire safety education method of parent education, fathers demanded Internet searching while mothers demanded seminars or lectures.
Although the history of the game of Go is more than 2,500 years, the theoretical studies of Go are still insufficient. In recent years a lot of studies using Artificial Intelligent (AI) have been conducted, but they do not provide the prominent theoretical reality. We applied traditional Principal Component Analysis (PCA) algorithm to the Go openings, which are the early stage in Go, to analyze them especially focused on the Go game records of the Korean top 10 professional Go players. We firstly analyzed the number of most significant eigenvectors capturing most of variance. Experimental result shows that among the 361 eigenvectors the eight most significant eigenvectors capture most of the variance (96.2%). We secondly used PCA classifier with Euclidean distance to recognize a pro player's opening to a class obtained from the training openings. Result shows that the best average recognition rate of 22% is so much lower than the recognition rates reported in face recognition research.

The purpose of this study was to develop measures for establishing and enforcing legal nutrition labeling for Takju based on results from consumer awareness surveys, statistical model development, and evaluation of nutrients. The statistical model developed with consumer survey results showed that consumers would like to know the nutrients they intake from drinking Takju, as their awareness about Takju was low. Specifically, consumers would like to see information regarding alcohol content, calories, carbohydrates, and saccharides on the label. Structural equations from the research model showed that consumers who had some knowledge of Takju also had positive thoughts of the nutrition fact labels for Takju. Evaluation of nutrients in Takju showed that the starch sources and other ingredients used in Takju fermentation did not influence nutrient facts, and nutrient concentrations also varied among the different Takju. In addition, this research suggests methods for consumers to make reasonable selections and to inform them of the nutrition fact labeling for Takju. Benners and pop-up were manufactured to promote voluntary participation of companies and to provide nutrition facts from Takju. Eventually, a measure was suggested to establish and enforce nutrition labeling, using results from consumer and nutrient surveys of Takju.

In most child-care facilities, homeroom teachers take the responsibilities for safety education, which has been conducted in class hours on a regular basis. It was found that most homeroom teachers are lacking in teacher training opportunities, and the younger they are, the less training experience they get. Teachers with fewer teaching careers had a greater interest in safety education and training courses. In addition, homeroom teachers have been utilizing monthly toddler magazines as a method to acquire knowledges for safety education and prevention of safety accidents. The safety accidents which have most frequently occurred in care-care facilities turned out to be stumble and tear, and infants aged 3 years or younger were found to be easily exposed to the safety accidents mainly due to the frolic between peers during the free-choice activity time. The homeroom teachers recognized only traffic safety education among the range of safety training courses, which varied depending on teaching career such as traffic safety education and indoor/outdoor safety environment training, etc. In addition, it turned out that the safety training methods were limited to the utilization of discussion techniques, role-playing, description and demonstration.
