본 연구에서는 민주적 학교문화가 청소년의 공동체의식에 미치는 영향을 종단적으로 분석하였다. 종단적인 분석을 위해 한국교육종단연구 2013(Korea Education Longitudinal Study, KELS) 자료 중 3차년도(2015년, 중1)부터 7차년도(2019년, 고2)까지의 자료를 활용하였으며, 잠재성장모형(Latent Growth Modeling) 방법을 사용하였다. 분석 결과, 첫째, 중1 시점부터 고2 시점까지 우리나라 청소년의 공동체의식은 증가하는 경향이 있는 것으로 나타났다. 둘째, 민주적 학교문화는 중1부터 고2까지 모든 시점의 공동체의식에 유의미한 영향을 미쳤다. 셋째, 청소년의 사회적 관계(부모, 또래, 교사와의 관계), 다양한 활동 경험(자치 활동 경험, 봉사 활동 경험), 사회경제적 배경(성별, 부모의 교육 수준) 변수들도 공동체의식에 유의미한 영향을 미치는 것으로 나타났다. 본 연구는 민주적인 학교문화가 청소년의 공동체의식에 긍정적인 영향을 줄 수 있다는 사실을 실증적인 분석을 통해 확인하였다는 점에서 의의가 있다. 공동체의식과 같은 시민의식의 발달 과정에는 청소년들이 주로 생활하는 학교라는 공간의 문화적 환경이 매우 중요하다는 사실을 알 수 있다. 청소년의 공동체의식 발달을 위해 우리의 교육 환경을 더욱 민주적으로 만들어가기 위한 노력이 필요하다. This study analyzed the influence of democratic school culture on adolescents' sense of community based on data from the Korean Education Longitudinal Study (KELS) 2013. Latent growth modeling was used to longitudinally analyze the effects of democratic school culture on adolescents' sense of community. First, it was found that adolescents' sense of community tends to increase from the 7th to the 11th grade. Second, democratic school culture has a significant influence on the sense of community at all times from the 7th grade to the 11th grade. Third, the social relationships experienced by adolescents, activity experiences, and socioeconomic background also significantly impact the sense of community. This study demonstrates that democratic school culture can positively affect adolescents' sense of community. It is important to strive to further democratize the educational environment in order to develop adolescents' sense of community.

Objective-The purpose of the study was to develop the Korean version of the Stage of Change Readiness and Treatment Eagerness Scale for Smoking Cessation (K-SOCRATES-S) based on the Korean version of the Stages of Readiness for Change and Eagerness for Treatment scale (K-SOCRATES). This paper also demonstrates its reliability and validity among patients with nicotine dependence in South Korea. Methods-At seven healthcare promotion centers in Gyeonggi-do, 333 male smokers aged 20 to 70 who visited smoking cessation clinic were recruited for this study and the K-SOCRATES-S was administered. After three months, the number of respondents who successfully stopped smoking was assessed by testing their urine cotinine level. Subsequently, exploratory factor analysis was performed to verify the reliability and validity of the K-SOCRATES-S. Also, a logistic regression analysis was performed to examine the variables that can predict the successful cessation of smoking on subscales of the K-SOCRATES-S. Results-Exploratory factor analysis of the K-SOCRATES-S showed that the scale consisted of three factors: Taking Steps, Recognition, and Ambivalence. The scales measuring Taking Steps and Recognition in this scale had a significantly positive correlation with the scores observed on Kim’s smoking cessation motivation scale. The scales measuring Taking Steps and Recognition had a significantly negative correlation with Ambivalence. Overall, the results indicate that the K-SOCRATES-K scale showed high validity. Conclusion-The K-SOCRATES-S developed in the present study is highly reliable and valid for predicting a patient’s likelihood of success in quitting smoking among patients who want to cease smoking.

In this paper we propose Personal Information Management System for Library Database. It manages personal search pattern for the given user and provide specific book list for library book search system. With the proposed system, the conventional overlap searching time will be decreased with personalized information and search history. This system manages the individual data according to personal searching pattern, sequence and usability. Therefore, the user can locate necessary book information more accurately with their distinct interest and search history.

<P><B>Abstract</B></P> <P><B>Background</B></P> <P>The dopamine receptor D2 receptor (<I>DRD2</I>) gene and lead exposure are both thought to contribute to the pathophysiology of attention-deficit/hyperactivity disorder (ADHD). ADHD is characterized by delay in brain maturation, most prominent in the prefrontal cortex (PFC). The D2 receptor is also mainly located in the PFC, and animal studies show that lead exposure affects the dopaminergic system of the frontal lobe, indicating an overlap in neural correlates of ADHD, <I>DRD2</I>, and lead exposure. We examined the interaction effects of <I>DRD2</I> rs1800497 and lead exposure on the cortical thickness of the frontal lobe in patients with ADHD.</P> <P><B>Methods</B></P> <P>A 1:1 age- and gender-matched sample of 75 participants with ADHD and 75 healthy participants was included in the analysis. The interaction effects of <I>DRD2</I> and lead exposure on the cortical thickness of 12 regions of interest in the frontal lobe were examined by multivariable linear regression analyses.</P> <P><B>Results</B></P> <P>When we investigated the <I>DRD2</I> ×lead effects in the ADHD and HC groups separately, significant <I>DRD2</I> ×lead effects were found in the ADHD group, but not in the healthy control group in multiple ROIs of the frontal lobe. There was a significant negative correlation between the cortical thickness of the right superior frontal gyrus and inattention scores.</P> <P><B>Conclusions</B></P> <P>The present findings demonstrated significant interaction effects of <I>DRD2</I> and lead exposure on the cortical thickness of the frontal lobe in ADHD. Replication studies with larger sample sizes, using a prospective design, are warranted to confirm these findings.</P> <P><B>Highlights</B></P> <P> <UL> <LI> The dopamine receptor D2 receptor (<I>DRD2</I>) gene and lead exposure contribute to the pathophysiology of ADHD. </LI> <LI> Previous study results indicate an overlap in the neural correlates of ADHD, <I>DRD2</I>, and lead exposure in the prefrontal cortex. </LI> <LI> We found significant interactions between <I>DRD2</I> and lead exposure on the cortical thickness of the frontal lobe in ADHD patients. </LI> <LI> This study highlights the need for consideration of gene-environment interaction when conducting studies regarding dopamine-related genes. </LI> </UL> </P>

In this study, AVWT (Automatic Virtual Wind Tunnel) is developed to estimate of vehicle aerodynamic performance. For the first step of using AVWT, engineer set boundary condition and mesh condition on the main window. As engineer executes AVWT, aerodynamic analysis of vehicle is performed from pre process (mesh generation) to post process automatically. In order to secure the accuracy of AVWT, drag coefficient values of using AVWT are compared with those of experiment for the three typical DrivAer models (Notchback, Fastback, and Hatchback). As a result, the error of the difference between the result AVWT and experiment is less than 5%

To study the electric and the thermoelectric properties of silicon thin films (SiTFs), we fabricated devices having SiTFs by using conventional complementary metal-oxide-semiconductor (CMOS)- compatible processes for mass production and extendibility. The conductivities and the Seebeck coefficients of SiTFs for dose concentrations of 5 × 1014 cm−2, 1 × 1015 cm−2 and 5 × 1015 cm−2 and for temperatures in the range of 310 to 430 K were measured by using homemade setup. The measured power factors of the SiTFs showed a slight increasing tendency with increasing measurement temperature and were maximum at a dose concentration of 1 × 1015 cm−2 for both n- and p-type films at 330 K.

본 연구에서는 경사진 그레인 포트 형상을 가진 고체 연료를 사용한 하이브리드 로켓의 연소 특성을 실험적으로 고찰하였다. 수렴 형상의 그레인 포트를 가지는 연료를 사용함으로써 경사각이 없는 연료에 비해 후퇴율을 17.5% 증가시킬 수 있었으나 확산 형상 연료에서는 후퇴율의 차이가 없었다. 또한 수렴 형상을 사용한 경우 특성속도 효율이 증가하였으며 이를 통해 하이브리드 로켓 연료에서 수렴 형상의 그레인 포트가 연소 효율 및 성능을 개선하는데 효과적임을 확인하였다. In this study, the combustion characteristics of hybrid rocket fuel with tapered grain port were studied. The regression rate was increased about 17.5% by using the convergence port shape fuel. On the other hand, in case of divergence port shape fuel, any notable difference of regression rate was not observed when compared with regression rate of the cylindrical port shape fuel. Also, in case of convergence port shape fuel, characteristic velocity efficiency was increased. From these results, one can notice that convergence port shape of hybrid rocket fuel can be effective configuration in terms of improvement of combustion efficiency and performance.
