The purpose of this study was to investigate the effects of teaching based on analysis of a hierarchy of the concepts associated with astronomical observation as well as each learner's status of knowledge through analytical methods of the knowledge state. A test instrument was developed to measure high school students' concepts associated with astronomical observation before instruction. The learners' psychological hierarchy associated with astronomical observation that the participants possessed showed the order of 'motion of the earth${\rightarrow}$coordinate system${\rightarrow}$astronomical observation (mechanism of the telescope${\rightarrow}$installation of the telescope${\rightarrow}$observation through the telescope)', and so was the hierarchy of teaching (70.6%). The learners' knowledge state that is supposed to be similar each other in the ability of observing celestial bodies was different even through they scored the same on the concept test. There were cases with the knowledge state well-structured and not well-structured, which suggests that differentiated instruction with appropriate teaching-learning prescriptions be prepared. An analysis of the knowledge state can play the role of both preparing individualized learning prescriptions and formative evaluation. In the unit dealing with astronomical observation of Earth ScienceI, teaching according to the psychological hierarchy of learners rather than the order in which the textbook syllabi were presented scored significantly higher (p<0.05) on the level of concept achievements. This result suggests that the teacher can help students achieve more efficient in learning by analyzing the learner's knowledge state and reordering the syllabi of the textbook in teaching the concepts associated with astronomical observation.

As the market of educational pet insects is expanding, understanding the consumer needs became more crucial. To achieve the ideal analysis on the market, this research monitored the behavior of consumers. The posting on the blogs of consumers, who have visited insect museums and farms, or have bought insects were collected as data. Moreover, the informational contents, photographs and texts, were analyzed. The results showed that the family-unit visitors with elementary school lower graders were the main type of visitors for their children's education. The visiting areas were concentrated in Seoul and the Metropolitans of Gyeonggi province, and the visits were mostly occurred during their children's vacation period. The analysis of posted photographs showed the visitors' high interest in the hands-on program. According to the texts on visitors' blogs, especially, the largest number of visitors satisfied with the variety of program. It implies the necessity of development in diverse and differentiated hands-on program. Otherwise, the programs available to connect insects to other animals and plants should be introduced to reduce aversion against insects, which was reported as the strongest dissatisfaction. In conclusion, diversification on insect species and development in systematized hands-on program seem to be required for the continuous growth of educational pet insects market.

Purpose: The purpose of this study was to identify the factors that influence the consumption of convenience foods among Korean adolescents. Methods: This study had a descriptive cross-sectional study. Data were obtained from the 15th (2019) Korea Youth Risk Behavior Web-based Survey, which involved a nationwide representative sample of 57,303 middle- and high-school students. Convenience-food consumption was defined by frequency of adolescents consuming convenience foods obtained from convenience stores, supermarkets, and cafeterias over the previous 7 days. The analyzed variables were related to sociodemographic, mental health, and health behavior. The Rao-Scott χ² test was applied to examine the difference in the rate of consuming convenience foods obtained from convenience stores according to each factor. Hierarchical logistic regression was conducted to examine the factors that influence convenience-food consumption among Korean adolescents. Results: It was found that 29.1% of Korean adolescents consumed convenience foods obtained from convenience store more than three times per week. The significant influencing factors were female sex; low subjective academic achievement, and subjective household economic status; high perceived stress; low subjective sleep sufficiency; experience of depression; suicidal ideation; lower physical activity; skipping breakfast; lower consumptions of fruit, milk, and vegetables; higher consumptions of soda drinks, sweet drinks, caffeine, and fast food; lower water intake; current smoking and drinking; drug use; and experience of violence. Conclusion: These findings provide a better understanding of the sociodemographic, mental-health, and health-behavior factors that influence the consumption of convenience foods among Korean adolescents. We suggest that differentiated policies, strategies, and nutrition education need to be developed and implemented, in order to address the above-mentioned factors and thereby reduce such behaviors among Korean adolescents.

This study begins with paying attention to the agglomeration of 'Residential-Commercial Mixed Use Buildings(hereafter, R-C MU Buildings)', which tend to be a high grade and large sized building cluster at various neighboring areas in Seoul. The purpose of this study is to understand the relationship between emerging new housing type and residential area by analyzing the characteristics of residential neighborhood that is mainly created by R-C MU Buildings. For this purpose, the specialization and the regional characteristics(in connection with the hierarchy in urban spatial structure) of R-C MU Building's residential neighborhood were analyzed. In the end, the specific type of housing reveals the tendency to be differentiated in terms of income, education and occupation related with housing and residential area. And the residential characteristics also seem to be different according to the regions based on the central place hierarchical structure. It means that the social and class factors are important in choosing house, but the characteristics of the neighborhood area play an important role in the selection of resident area. Finally, the location of certain type of housing can influence the selecting process of residence and it can also determine the characteristics of the resident area in turn.

This study makes differentiated regulations which can maximize the efficiency and convenience of radiation safety regulations by deriving evidence required to establish reasonable safety regulatory structure based on the determination of the levels of actual radiation safety regulations for radiation safety managers to perform radiation safety. We surveyed approximately 10% of radiation safety managers from domestic radiation-using organizations which was based on the Nuclear Safety Act and NUREG Vol. 1~21 of RS-G-1.9 (2005), NRC of IAEA, etc. The radiation safety managers showed the highest level of awareness on the requirements for exposure management ($3.32{\pm}0.910$), and the lowest level on the requirements for record keeping and storage of documents ($2.84{\pm}0.826$). Industrial organizations showed higher levels of awareness than medical organizations whose regulations should be more stringent on requirements of the status and management of radioactive sources, facilities, measurements, pollution control, measuring equipment, monitoring, education and training, and exposure management. This suggests that the actual regulations need to be re-evaluated because it is attributed to the regulations which are statistically significant difference of the levels of radiation safety regulations between industrial organizations and medical organizations. The process of developing regulatory requirements for each characteristic of domestic organizations needs to be done in future studies, as well as safety regulations to maximize convenience should be achieved if radiation safety regulations are conducted in consideration with the characteristics of each organization.

Objectives : The purpose of this study was to examine factors related to the satisfaction level of patients with dental services. Methods : The subjects in this study were 200 patients at three different dental clinics in South Gyeongsang Province, on whom a survey was conducted from June 1 to July 31, 2009. The collected data were analyzed, and the findings of the study were as follows. Results : In regard to the general characteristics of the patients investigated, the women(61.5%) out-numbered the men. By age, those who were at the age of 30 and down made up the largest age group(47.0%). By academic background, the greatest group received junior-college education(54.0%). By occupation, the company employees constituted the largest group (50.5%). By income, the greatest group earned an income of 2 to 2.99 million won(75.0%). Second, as to connections between the characteristics of dental treatment and the reason of choosing the dental clinics, the largest group(70.4%) chose the dental clinics by word of mouth or the recommendation of others. Concerning the reason of dissatisfaction, the biggest group(72.7%) was unsatisfied with medical costs. As for the degree of explicit complaint, the greatest group(49.7%) sort of complained about what made them dissatisfied. Regarding the type of treatment, the biggest group(49.0%) received prosthodontic treatment. In relation to fear for dental treatment, the largest group(34.0%) feared receiving the treatment, and the biggest group(42.6%) did that due to the sound of machines. Third, satisfaction with services(0.762) had the closest correlation to overall satisfaction level, followed by satisfaction with employees(0.735), satisfaction with dentists(0.644) and satisfaction with convenient facilities (0.579). Fourth, the factors that affected overall satisfaction level were gender, the reason of choosing the dental clinic, satisfaction with dentists, satisfaction with employees, satisfaction with services and satisfaction with convenient facilities. The patients who were better satisfied with services(p<0.001), who were more contented with dentists(p<0.001), who chose the dental clinics by the recommendation of others(p<0.01), who were male(p<0.05), who were more gratified with employees(p<0.05) and who were more contented with convenient facilities expressed better overall satisfaction. Conclusions : The above-mentioned findings suggested that dental institutions should keep track of the expectations of patients to prepare differentiated strategies for marketing and human-resources development in consideration of their own circumstances to boost the satisfaction level of patients. Specifically, it's required to heighten the satisfaction level of patients with dentists.

The purpose of this study is to find that people's visit to a dementia home exhibition hall is effective at improving their perception of dementia. The satisfaction of visitors to the dementia home exhibition hall and a change in their perception of dementia after the visit were analyzed. The study subjects were 52 residents in S city. This study had been conducted from April, 5 to May, 25, 2018. The dementia home exhibition hall has welfare kits installed in an entrance, a rest room, a living, and a kitchen. Virtual reality experience program and the program of wearing clothes to experience an elderly person were performed together. As a result, the visitors' satisfaction was high overall, and their visit was educationally effective at improving their perception of dementia. After their visit to the hall, the residents showed high increases in the scores of the questions about the perception of dementia causes, dynamism & system, symptoms & diagnosis, and treatment & prevention. The residents with middle years and higher of age were more satisfied than those in other age groups with the introduction of dementia, and prevention methods, introduction of safe and comfortable home environment, and appropriateness of experience program. In this study, it was positive that the differentiated experience program which was not existed actively led the participation of the target person and attracted high education satisfaction in a short time. In the future, it will be necessary to develop an extended experience program, provide an environment for direct experience of dementia, and perform a continuous program to draw more citizens' attention.

This study was conducted to find a practical implication regarding efficient and smooth service utilization including care burden reduction of family caregivers by empirically analyzing the factors influencing the dementia patient home care intention of family caregivers, based on Anderson's behavior model. For this study, the subjects and characteristics suitable for the study purpose were selected using the source data of "A Survey on the Dementia Recognition and Needs" targeting 26 cities and countries in Gyeonggi-do and then secondary analysis was conducted. This study targeted 539 dementia families, and based on Anderson's behavior model, variables related to predisposing factors, enabling factors and need factors were inserted, and hierarchical regression analysis was applied. The analysis result showed that at a significance level of 5%, the home care intention was high when family caregivers were not living in cities, they were spouses or children and their economic level was high as predisposing factors, and the dementia-related attitude was positive as a enabling factor, and the degree of dementia was mild and care burden was low as need factors. Moreover, need factors were relatively important variables among the three factors mentioned above. These findings demonstrate that for improving the home care intention, there is a need to construct a support strategy, which considers the degree of dementia and economic characteristics and develop diverse counseling and education programs for a positive attitude towards dementia and a differentiated strategy depending on regional and family characteristics.

In this study, the spatio-temporal characteristics of summer extreme precipitation events in the Republic of Korea are examined based on the daily precipitation data observed at approximately 360 sites of both Automatic Weather Station (AWS) and Automated Synoptic Observation System (ASOS) networks by the Korea Meteorological Administration for the recent decade(2002~2011). During the summer Changma period(late June~mid July), both the frequency of extreme precipitation events exceeding 80mm of daily precipitation and their decadal maximum values are greatest at most of weather stations. In contrast, during the Changma pause period (late July~early August), these patterns are observed only in the northern regions of Geyeonggi province and western Kangwon province as such patterns are detected around Mt. Sobaek and Mt. Halla as well as in the southern regions of Geyeonggi province and western Kangwon province during the late Changma period (mid August~early September) due to north-south oscillation of the Changma front. Investigation of their regional patterns confirms that not only migration of the Changma front but also topological components in response to the advection of moistures such as elevation and aspect of major mountain ridges are detrimental to spatio-temporal patterns of extreme precipitation events. These results indicate that each local administration needs differentiated strategies to mitigate the potential damages by extreme precipitation events due to the spatiotemporal heterogeneity of their frequency and intensity during each Changma period.
