This research aims at investigating the factors determining the success of knowledge management system(KMS) in research organizations. Based on the literature survey and the general framework of IS success model, a new comprehensive model which is customized to the context of KMS is proposed. Some organizational support factors and an individual personality variable that moderates the relationship between predictors and the success factors are also integrated to the new model. A proposed model was tested by the technique of structural equation modeling using survey data from the employees in research organization. The results revealed that KMS quality had the strongest impact on the KMS success measured by perceived usefulness and user satisfaction and KMS use. The moderating effect of an individual personality factor, organization-based self esteem is also founded in the research.

Purpose:To identify the risk factors for poor neurodevelopmental outcomes in high-risk neonates. Methods:We studied 94 infants admitted to the neonatal intensive care unit at the Sanggye Paik Hospital between January 2002 and November 2005 and evaluated the follow-up data. The following events were considered as risk factors: ${\leq}32$ weeks of gestation, very low birth weight, Apgar scores of less than 5, neonatal resuscitation, neonatal seizure, congenital infection, and abnormalities in cranial ultrasound or magnetic resonance imaging (MRI). The infants who had any one of these risk factors were included. They were evaluated at their mean corrected age of 13.84${\pm}$8.03 months. Mental and Psychomotor Developmental Indices (MDI, PDI) were determined by a clinical psychologist using the Bayley Scales of Infant Development II. Results:The mean MDI and PDI of all the patients were 96.28${\pm}$26.70 and 94.00${\pm}$22.80, respectively. Abnormalities on cranial ultrasound or MRI were significant predictors of both low MDI (P<0.05) and low PDI (P<0.001). These abnormalities showed a stronger association with low PDI than with low MDI. The infants with periventricular leukomalacia had the lowest MDI and PDI ($70.10{\pm}28.68$ and $69.70{\pm}24.91$, respectively). Apgar score at 1 minute and very low birth weight were also significant predictors for low PDI (P<0.05, P<0.05, respectively). Conclusion:Image findings with cranial ultrasound or MRI were the strongest predictors of neurodevelopmental outcome. Periventricular leukomalacia was the best predictive factor for mental and psychomotor development.

Since the 1960s, the United States' (U.S.) deinstitutionalization policy has reinstated people with mental illness into communities. Unfortunately, when untreated, some people with psychiatric disorders become homeless, and some commit serious crimes during a psychological crisis. Assisted Outpatient Treatment (AOT), also known as Kendra's Law in New York and Laura's Law in California, provides treatment, services and support to people with mental illness in the community. AOT has repeatedly been found effective and is recognized as an evidence-based practice. The response to the mental health crisis (crisis intervention) in the U.S. has also been successful in preventing worsening mental illness and related criminality and other issues. This paper provides an opportunity to create a platform from which to learn how to successfully apply the AOT and crisis intervention of the U.S. to South Korea within the cultural and societal context when establishing social services for people with mental illness in South Korea's communities.

The purpose of this study was to suggest an appropriate collimation size and central X-ray incidence point by analyzing the correlation between the collimation size used in lumbar lateral examination and factors affecting the collimation size. the lumbar lateral examination results of 148 patients suitable for the purpose of this study were analyzed. The measurement method was to set the total horizontal width shown in the image to the size of the irradiation field(collimation) used during the examination. The distance connected vertically from the end of the dorsal field to the apophyseal joint of the third lumbar vertebra(AJD), the distance from the dorsal end of the image field to the center of the body of the third lumbar vertebra(BD), and the distance from the end of the dorsal field of the image to the center of the pedicle of the third lumbar vertebra(PD). The distance was measured. For comparative analysis of the mean values of dependent variables according to gender, age, height, weight, and body mass index, the mean values were compared using the independent samples t test and one-way ANOVA. For post hoc analysis, duncan was used. The correlation between independent and dependent variables was analyzed using Pearson correlation analysis. In this study, statistical significance was set at a p value of 0.05 or lower. The average value of the collimation size during the lumbar spine lateral examination was 252.45 mm, AJD was 102.11 mm, BD was 141.17 mm, and PD was 119.73 mm. The mean values of collimation size, AJD, BD, and PD were larger in men than in women, but statistical significance for the difference in mean values by gender was found only in BD (p<0.05). There was a slight difference in the mean value of each group according to age, but there was no statistical significance (p>0.05). The collimation size and mean values of AJD, BD, and PD according to height, weight, and body mass index differed depending on the independent variables, and the differences were all statistically significant (p<0.05). As a result of the correlation analysis, field size and AJD, BD, and PD showed no correlation with gender and age, a weak positive correlation with height, and a medium positive correlation with weight and body mass index. The results of this study showed that CS was correlated with height, weight, and BMI during lumbar lateral examination. If the entrance point of the central X-ray is moved to the appophyseal joint by considering weight and BMI when adjusting the collimation size in clinical practice, it is expected that the collimation size can be reduced bu about 5%.

As Urban Regeneration is being carried out, stakeholders are most likely to have disagreements on their interests. Besides, dispersion of numerous communication routes and obscure decision processes aggravate the situation. Eventually, fragmented decision-making processes and complex structure lead to inefficient outcome and delay of projects. This paper is a study on decision-making support not only helps the program manager have more efficient and optimum decision, but also provides alternatives for Urban Regeneration. This study is conducted as follows. Firstly, the project process and the decision-making structure among stakeholders in Urban Regeneration are analyzed, and then the current status of decision-making in Urban Regeneration project is classified. Secondly, with literature study on "Gateway Review", the decision-making gateway review process in Urban Regeneration is defined, and then the "Gateway Review Elements" are listed. Thirdly, to establish gateway review process, this paper presents a check points, namely gate which supports a program manager to monitor and to control the program management in Urban Regeneration. Each gate has several supporting tools such as diagram of critical decision points relation, scheme of stakeholder, checklist. Fourthly, the proposed concept is verified by experts who have been carefully selected to provide their respective reviews. Finally, decision-making support gateway review system is modified based on their critiques and suggestions.

The purpose of this study was to compare the canal configuration after shaping by ProTaper rotary files and ProTaper hand files in resin simulated canals. Forty resin simulated canals with a curvature of J-shape and S-shape were divided into four groups by 10 blocks each Simulated root canals in resin block were prepared by ProTaper rotary files and ProTaper hand files using a crown-down pressureless technique All simulated canals were prepared up to size $\#25$ file at end-point of preparation. Pre- and post-instrumentation images were recorded with color scanner. Assessment of canal shape was completed with an image analysis program. Measurements were made at 0, 1, 2, 3, 4, 5, 6 and 7 mm from the apex. At each level, outer canal width, inner canal width, total canal width, and amount of transportation from original axis were recorded. Instrumentation time was recorded. The data were analyzed statistically using independent t-test. The result was that ProTaper hand files cause significantly less canal transportation from original axis of canal body and maintain original canal configuration better than ProTaper rotary files, however ProTaper hand files take more shaping time.

Objectives : The aim of this study was to investigate the gender differences of direct aggression and relational aggression in Korean elementary and middle school students. Methods : Parents of 946 elementary school students(age $9.54{\pm}1.72$ years, 485 boys, 461 girls) completed the Child Behavior Checklist(CBCL). Six-hundred-and-three middle school students(age $13.98{\pm}0.93$ years, 301 boys, 302 girls) completed the Youth Self-Report(YSR). Independent t-test, chi-square test, and Fisher's exact test were used. Results : Boys had significantly higher direct aggression scores than girls in elementary school students(p<0.001). There was no significance gender difference of relational aggression in elementary school students(p=0.235). In middle school students, boys had significantly higher direct aggression than girls(p=0.017), and girls had significantly higher relational aggression compared to the boys(p<0.001). Conclusions : Our results suggest the presence of gender differences in manifestation of aggression subtypes in Korean elementary and middle school students. These gender differences should be taken into account in prevention and intervention approaches of aggression in children and adolescents.

This study made an attempt to analyse the relationship between operation environment and fleet size per route which represents the level of service for inner-city bus service. Regression analysis method has been adopted as main analysis tool and 98 routes of bus operation status in Ulsan city as of 2013 has also been selected for analysis target. Correlation analysis was performed to identify the relationship between dependent and independent variables. There are three types of model for whole sample, type operation, and bus route operation system. These are the results of the current study. 1. The model developed for whole sample of 98 routes is as follows. Y(Fleet Size)=$-4.532+0.00002877*X_1$(Revenue). This model shows that it is necessary to have more than 140 passengers per day to increase fleet size of each bus route in Ulsan. 2. Models developed by type of operation (which are standard, express, and middle sized) are shown below. Stand Bus : Y(Fleet Size)=$-10.954+0.00004283*X_1$(Revenue). It is identified that more than 153 passengers need to use standard bus to increase fleet size per each standard bus, Middle Sized Bus : Y(Fleet Size)=-0.859+0.00001438*X1(Revenue). For middle sized bus, at least 52 daily passengers are needed to increase number of bus in each route. 3. Models developed for each route operation systems are as belows. Joint Operation Group : Y(Fleet Size)=$-4.786+0.00003028*X_1$(Revenue). Individual Operation Group : Y(Fleet Size)=$-2.339+0.00002030*X_1$(Revenue). These model provide similar result which 140 people is the minimum number of passenger to raise the number of vehicles in each route. This result shows that the route operation systems does not affect the raise number of cars significantly.

The purpose of this study was to examine the relationship between the child care support policies and the birth rate in 33 OECD countries. In the structural equation modelling, the birth rate was the dependent variable while the cash-support policies, the child-care facility service policies, and the tax benefits policies were the independent variables. The analysis showed that the most effective factor on the birth rate was the child-care facility service policies. Regarding the effectiveness of the policy expenses, the cash-support policies showed stable fluctuation of effectiveness according to the fluctuation of cash amount, the child-care facility service policies. In conclusion, in order to increase the effectiveness of the cash-support policies, the adequate cost calculation to decrease the parents' burden for child-bearing, re-allocation of budget, and support methods and timing should be continually discussed. In addition, for the better effectiveness of the facility service policies, more various, comprehensive and high-quality facility service policies that could balance home and work, should be implemented.
