This study was intended to investigate the effects of after-school forest healing programs on the pro-social behavior and self-efficacy of young children using the attributes of forest and the forest healing factors. The children attending a kindergarten located in ${\bigcirc}{\bigcirc}$ - dong, Cheongju city were divided into a test group which participated in the forest healing program activities and a control group which participated in the regular programs of the kindergarten but not in the forest healing program. Each group consisted of 20 boys and girls aged 3 to 5 years. The forest healing program was conducted once a week from 10 April to 10 July in 2017 for a total of 12 sessions, and each session lasted one hour (60 minutes). The pro-sociality behavior and self-efficacy test of the children was conducted before and after the forest healing program, and the data were analyzed using SPSS 18.0 program. The result showed that the pro-social behaviors that indicated the ability to execute the positive action and the self-efficacy that indicated the self-confidence were statistically significant (p<0.05). The young children who participated in the forest healing program improved their self-esteem through positive thoughts from being with their peer in nature. Moreover, they increased not only ecological knowledge but also consideration for others and cooperative spirit. They also greatly improved the ability to control personal emotion and the ability to form the personal relationship which are the sub-factors of pro-sociality, the ability to adapt to the early childhood education institution, and the physical efficacy which is the sub-factor of self-efficacy. It was concluded that the after-school forest healing program had a positive impact on pro-social behavior and self-efficacy.

The parcels of land alteration by existing manual work was very inefficient in terms of time and costs. Especially it caused many difficulty in estimating compensation since the work didn't take into account the range of adjoining zone to road. This study selected Gimje City of Jeollabuk-Do as a study site and could analyze the numbers and areas of parcels of land alteration considering the range of adjoining zone to road based on cadastral maps and wide road layers from new address system. Also this study applied a fuzzy membership function according to occupation ratio to road, and analyzed compensation by the range of adjoining zone to road using individual public land price information of the parcels for land alternation. Especially, the change aspect of public and private parcels could be investigated by the range of adjoining zone to road according to the fuzzy membership function. And this study could provide very efficient data in determining the priority of the parcels for land alternation through calculating compensation of the parcels for land alternation by Eup Myeong Dong according to the range of adjoining zone to road.
The objective of this study is to develop road traffic accident model involving child pedestrian especially at school zones and its surrounding area. The analysis is based upon traffic accident data collected near sixty elementary schools in City of Cheongju during 2012 and 2014. This study results in two statistical models ; one is to predict the number of road traffic accidents involving children, and the other is to predict EPDO(Equivalent Prperty Damage Only). These models are represented as Poisson models. which are statistically significant with the likelihood ratios of 0.533 and 0.273. The common explanatory variables of these models are the ratio of road section with more than 4 lanes, the number of entrance and exit, the number of signalized crosswalk in school zone, the number of school zone signage including road surface marking, and the number of speed limit signs. The specific variables are the length of road stretch in school zone, the number of reflector mirrors, and the number of signalized crosswalk outside school zone. It is concluded that these types of road safety facilities can reduce the number of traffic accidents involving children at school zones and its surrounding area.
Science and technology information resources are major impetus for all research and development activities. Now countries around the world are seeking efficient and effective means to cope with the exponential growth of needs for science and technology information for research. In this context, it has been perceived vital to establish national infrastructures in order to extend the availability of world's science and technology information. In Korea, it has been a recurring issue to build a national science library to prevent knowledge colonization and to gain a competitive edge in the fields. It is essential to have one as a national information infrastructure to assume the role of developing a sustainable model for access to the world's science and technology information, providing permanent access to them. In this paper, therefore, some issues concerning building and managing a new national science library in Korea are examined. In doing so, the following details are dealt with in detail. First, the rationale behind building a national science library is described, Second, the functions and roles of the library are defined, Third, previous discussions and attempts to build a national science library are reviewed and analysed. Finally, possible problems and issues raised in relation to build a national science library are probed, and future directions are also suggested. In this process, the recent strategic plan for national science library, national agriculture library, and national medical library, and changing plan for Sejong city are taken into consideration as influencing factors.

This study analyzes the visual access opportunities of neighborhood park users using the Space Syntax theory. In order to achieve this goal, 27 neighborhood parks were selected and 27 axial maps drawn according to the spatial configuration of the sites. Based on the axial map data, this study has calculated some specific space syntax indices, including Connectivity, Integration, and Intelligibility using the Axwoman ver 3.0 based on the Arcview 3.2 application. The value of the representative indices were used to examine visual access opportunities presented by the parks. This study was conducted in two aspects: one focusing on the entire space and another focusing on only the main entrance of the parks. The former used integration and intelligibility values and the latter used connectivity and integration values to evaluate the visual access opportunities of the sites. As a result, this study found that some parks, including Joongang, Balsan, and Sangdang, have high visual access opportunities in terms of the spatial configuration surrounding the park, which shows an integration value higher than 2, and also having intelligibility values higher than 0.7. This is the result of the grid land use pattern surrounding the parks and the straight roads that are closely linked to the main entrances of the parks. It is expected that this methodology and results will be used for locating neighborhood parks during the urban planning stage as providing reasonable evidence.

For the soft ground construction, the factors not considered in the design stage occurs in the construction stage so that they cause the increase of the construction cost due to the structural stability and the design change. The subject of the study is the construction section of the industrial complex access road made in the Ochang region of Chungcheongbuk-do. The study is concerned with selecting the soft ground handling method such as the replacement method using rock debris and the surcharge reflecting the service load as the soft ground handling measure and analyzing the effect of reducing the construction cost with the stability of structures and the reduction of the construction period. The soft ground in the study section consists of sandy and cohesive soil and is 2.4m to 5.5m deep. It is distributed unevenly between the 1.5m to 5.9m stratums under the ground surface. Settlement is not serious, but the future uneven settlement and difference are expected so that the future settlement behavior is estimated by analyzing the site measurement results after the soft ground treatment. Moreover, in consideration of the regional characteristics and economic efficiency, soil with good quality is replaced with rock debris as the replacement material so that 29% of the construction cost is reduced due to the increase of stability and the reduction of duration. If the estimation of the dispersion of the pore water pressure within the dam body and the change of the underground water level and the relation of the actually measured soft ground with consolidation is studied further on the basis of the study, it is expected that the behavior of the soft ground will be correctly estimated in various site conditions.

Objective: This study examined the caregiver burden, depressive symptoms, and mental-related quality of life of 226 caregivers of stroke patients, who had been hospitalized in 7 general hospitals located in Cheongju and Daejeon Metropolitan city. Methods: Data were collected from August 5, 2014 to October 5, 2014 and a structured self-administered questionnaire was used. The results were analyzed using a t-test, ANOVA for different comparisons of the mental related quality of life in the sociodemographic characteristics, care-related characteristics, health-related behavioral characteristics, caregiver burden, and depressive symptoms. Hierarchical multiple regression was conducted to determine the explanatory power of the independent variables on the dependent variables, with the variables showing significant differences in univariate analysis as independent variables. Results: According to the results of hierarchical multiple regression analysis, the relevant factors that influenced the mental-related quality of life were the relationship with a patient, burden by 'care', burden by sacrifice of 'personal life', and depressive symptoms. Conclusion: To enhance health-related quality of life, not only is a systematic complement on such factors needed, but the development and implementation of an intervention program to the caregiver burden and depressive symptoms is also urgently required.

The purpose of this study was to investigate whether there were any changes in taste sensitivity with oral lichen planus (OLP). Sixty subjects (26 males and 34 females) were included for the study and they were categorized into 2 groups (oral lichen planus 30 persons,control 30 persons), oral lichen planus group was investigated in the department of Oral Medicine, College of Dentistry, Pusan National University from April, 2005 to February, 2006 and control group was investigated in the clinic at Cheongju City from february, 2006 to april, 2006. The electrical taste thresholds were measured using an electrogustometer of the 4 different sites (tongue tip, tongue lateral, circumvallate papilla and soft palate) in oral cavity. The results were as follows; 1. The electrical taste threshold showed a tendency to decrease in the OLP group. 2. The electrical taste threshold showed a tendency to decrease in female group, but showed a tendency to increase in male group of the OLP group. 3. The electrical taste threshold showed a tendency to increase in tongue tip, tongue lateral of the multiple OLP group, but showed a tendency to decrease in circumvallate papilla, soft palate of the multiple OLP group. 4. The electrical taste threshold showed a tendency to increase in tongue tip, tongue lateral of the acute OLP group, but showed a tendency to decrease in circumvallate papilla, soft palate of the acute OLP group. 5. After treatment, electrical taste threshold was significant lower in soft palate of the OLP group than control group. 6. After treatment, NAS was significantly lower in soft palate of the OLP group than control group.
Overwintering adults of sycamore lace bug (Corythucha ciliata) infected by an unidentified pathogenic fungus were found on the stems of street trees of sycamore in Cheongju city. The objective of this study was to describe this entomopathogenic fungus infecting overwintering sycamore lace bug adults. This unidentified fungus colonized the insect adult body and formed white colony with subglobose clusters of conidiocarps. The size of conidiocarps was 300 to $400{\mu}m$ and each conidium was 15 to $20{\mu}m$. The conidiospore was globus and 2.5 to $3.0{\mu}m$ in diameter, and the hyphae were 1 to $5{\mu}m$ thick. This fungus was successfully isolated and cultivated on potato dextrose agar medium (PDA). The fungal colony was white and then became light yellow. When conidia from this pure culture were inoculated into the overwintering adults, the fungus formed conidiocarps with the same morphology on the insect body and the lethal rate by the fungus was $88{\pm}16%$. This fungus has over 99% homology with Cordyceps bassiana (imperfect fungal name is Beauveria bassiana) in ITS-5.8s rDNA base sequence. The fungal ecology and the infection process of the fungus into its host need to be clarified before using this fungus as a biological control agent.
Although many efforts to stop speeding or inappropriate speed, it failed to reduce the number of speeding-related crashes. Therefore, it is important to analyze the characteristics of speeding offenders and the cause of speeding at hot spots. In this study, we investigate the level of severity in speeding by the characteristics of speeding offenders using the Ordered Logistics Regression Models(OLRM). For the analysis, we use the speeding data collected by 39 traffic enforcement cameras in city of Cheongju and other related data including the speeding ticket history of drivers during the most recent 3 years, their demographic characteristics, their own vehicles, and road environment factors. The major results of this study are as follows. Firstly, commercial fleet drivers are more likely to repeat the conviction of high-range speeding with more than 30km/h over speed limits than other drivers. Secondly, mid-range speeding are observed as 21,462 frequency which is 76.7% of total speeding frequency and occurred mostly at suburban and rural area. It concludes that contributory factors affecting the severity of speeding at signalized intersection are drivers' speeding offence history, posted speed limits, time of day, gender of driver, and location of the intersection as show by the OLRM developed in this study(McFadden R-square : 0.296).
