Purpose: This study examined the differences in drug abuse knowledge and drug usage attitudes among middle school students based on their diverse sociodemographic characteristics. Methods: This descriptive survey included 214 middle school students from five co-educational schools in G city. Data were collected from May 17th to June 17th, 2024, through a Google Forms survey distributed via QR codes. The data were analyzed using SPSS 27.0 for frequency, descriptive statistics, t-tests, one-way ANOVA, Scheffe post-hoc tests, Spearman's rank correlation, and multiple regression. Results: The study found that drug usage attitude had significant positive correlations with peer relationship satisfaction (rho=.26, p <.001), school life satisfaction (rho=.18, p =.010), parental relationship (rho=.20, p =.004), academic performance (rho=.40, p <.001), and drug abuse knowledge (rho=.35, p <.001). Multiple regression analysis revealed that the main factors significantly influencing drug usage attitude were drug abuse knowledge (β=.37, p <.001) and parental relationship (β=.18, p =.008). Drug abuse knowledge emerged as the most influential factor, while parental relationship was also a significant predictor. The regression model explained 22.3% of the variance in attitudes towards drug use (F=10.39, p <.001). Conclusion: The findings underscore the importance of tailored educational programs to enhance drug abuse knowledge and its consequences and foster negative drug usage attitudes in general among adolescents. Support and communication within schools and families are thus essential to this effort in combating one of the key social issues of this era.

최근들어 인터넷의 발달과 더불어 PDA, 핸드폰과 같은 모바일 디바이스와 다양한 정보가전용 기기들에 네트워크 기반의 자바기술이 적용되고 있으며, 이러한 자바 기술을 사용함으로써 플랫폼 독립성, 이식성, 보안성, 이동성 등의 장점을 얻을 수 있다. 그러나, 자바로 작성된 응용프로그램은 C, C++로 작성된 응용프로그램보다 수행속도가 느리다는 단점이 있다. 이러한 문제점을 해결하기 위해서는 자바가상머신의 성능향상이 필수적이다. 지금까지 메모리 관리를 위한 가비지 컬렉션, 소프트웨어나 하드웨어를 이용한 바이트 코드 변환, 인라인캐시(inline-cache)를 사용한 접근 속도 향상 등 많은 부분에서 활발한 연구가 진행되고 있다. 본 논문에서는 모바일 플랫폼에서 동작하는 KVM(kilo-virtual machine)의 성능향상을 위한 쓰레드 구조를 분석하고 설계한다.

Objectives: The purpose of this study was to develop exposure factor data for the Korean child population, with a specific focus on behavior characteristics such as hand-to-mouth and object-to-mouth and an analysis of influential factors. Methods: We divided environments into two places, which were house/indoor and nursery. A total of 400 children (house/indoor) and a total of 162 children (nursery) were recruited from the cities of Seoul, Incheon, Daegu, and Gwangju. The children were divided into two groups. We conducted direct measurement by using one hour of videotaping alongside questionnaire surveys. This was performed to calculate behavior rates, such as how many children perform hand-to-mouth and object-to-mouth behaviors. Results: The respective average frequencies of hand-to-mouth and object-to-mouth were 0.8±2.23 and 0.82±2.64 contacts/hr for house/indoor. The respective average frequencies of hand-to-mouth and object-tomouth were 2.87±4.63 and 1.47±3.84 contacts/hr in the nursery group. For the mouthing participants, the average frequencies of hand-to-mouth and object-to-mouth were 3.31 and 3.20 contacts/hr in house, and 4.80 and 3.26 in nursery. Compared to other countries such as the USA, the frequencies of hand-to-mouth and object-tomouth behaviors found in this study were relatively lower. Conclusions: Children have the potential for exposure to toxic substances through non-dietary ingestion pathways by mouthing objects or their fingers. In this study, the mouthing frequency was relatively lower than that found in Western countries. This can be explained that mouthing behaviour may be affected by culture and lifestyle characteristics.
