최근에 Serverless 컴퓨팅은 많은 관심을 받는 기술로, 서버 프로비저닝 없이 코드를 배포하고 실행할 수 있으며 요청량에 따라 동적으로 컴퓨팅 리소스를 확장하여 애플리케이션을 안정적으로 운영할 수 있는 환경을 제공한다. Serverless 컴퓨팅의 주요 이슈 중 하나인 cold start 는 함수를 실행하기 위한 컨테이너 초기화 및 구동하는 단계이며, 해당 과정에서는 이미지 풀링이 수행될 수 있다. 이미지 풀링은 cold start 지연의 대부분을 차지하고 함수의 응답시간을 증가 시켜서 사용자 경험에 부정적인 영향을 줄 수 있다. 따라서, 본 논문에서는 cold start 지연을 줄이기 위해 도커를 활용해서 이미지 레이어 동시 풀링 개수를 조절함으로써 이미지 풀링 속도를 개선시킬 수 있는지 분석하였다. 이와 같은 분석을 통해 풀링 개수가 풀링 속도에 영향을 줄 수 있음을 확인하였다.

We need an enormous amount of memories for name spaces as well as additional processors if we are to effectively exploit a massively parallelism in nested loops of functional languages such as Id. If there is no sufficient amount of memories enough to exploit that parallelism, the execution of programs can be aborted during the unfolding of loops. Additionally, if loops are overunfolded, compared with the number of processors available, the system performance can be degraded severely due to the overhead of loop unfolding. This paper suggests and analyzes an algorithm which can be used to effectively unfold nested loops of functional languages on multithreaded architectures. This algorithm has a feature to unfold a given nested loop safely and near optimally, considering the system resources of processors and memories available when the loop is to be unfolded.

The purpose of this study was to analyze the literature on music interventions for youth with intellectual disability. Characteristics of the music intervention, target goal domains, and the quality of statements on intervention contents and rationale were explored. What type of intervention was applied in each target goal domain and how studies differed in terms of the quality of stated rationales depending on the authors' field of study were also analyzed. A total of 20 articles published in KCI journals were identified. The analysis showed the differences in intervention contents depending on the authors' research field and target goal areas. In addition, it was found that only two studies stated an appropriate rationale based on the theory of music therapy and relevant research. Discrepancies on the quality of rationale between researchers with music therapy majors and with non-music therapy majors indicated the importance of the music therapy professionalism in expecting and interpreting the intervention outcomes. These findings highlight the ways in which music intervention studies could be improved to further the field and contribute to the rigor of these interventions for youth with intellectual disability.

최근 존재하는 대부분의 관계 추출 모델은 언급 수준의 관계 추출 모델이다. 이들은 성능은 높지만, 문서에 존재하는 다수의 문장을 처리할 때, 문서 내에 주요 개체 및 여러 문장에 걸쳐서 표현되는 개체간의 관계를 분류하지 못한다. 이는 높은 수준의 관계를 정의하지 못함으로써 올바르게 데이터를 정형화지 못하는 중대한 문제이다. 해당 논문에서는 이러한 문제를 타파하기 위하여 여러 문장에 걸쳐서 개체간의 상호작용 관계도 파악하는 전역 수준의 관계 추출 모델을 제안한다. 제안하는 모델은 전처리 단계에서 문서를 분석하여 사전 지식베이스, 개체 연결 그리고 각 개체의 언급횟수를 파악하고 문서 내의 주요 개체들을 파악한다. 이후 언급 수준의 관계 추출을 통하여 1차적으로 단편적인 관계 추출을 실행하고, 주요개체와 관련된 관계는 외부 메모리에 샘플로 저장한다. 이후 단편적 관계들과 외부메모리를 이용하여 여러 문장에 걸쳐 표현되는 개체 간 관계를 알아낸다. 해당 논문은 이러한 모델의 구조도와 실험방법의 설계에 대하여 설명하였고, 해당 실험의 기대효과 또한 작성하였다.

UDP library of Verilog HDL has been used for simulation of digital systems. But it takes a lot of time and efforts to generate a gate-level library equivalent to the UDP library manually due to the characteristic of UDP that does not support synthesis. It is indispensable to generate equivalent gate-level model in testing the digital systems because fault coverage can be reduced without the equivalent gate-level models. So, it is needed to automate the process of generating the equivalent gate-level models. An algorithm to solve this problem has been proposed, but it is unnecessarily complex and time-consuming. This paper suggests a new improved algorithm to implement the conversion to gate-level models, which exploits the characteristic of UDP Experimental results are demonstrated to show the effectiveness of the new algorithm.

Objective : This study was to learn the Korean Occupational Therapists' awareness and current state of implement of Occupation-Based Practice and to use it as a baseline data. Methods : After 300 Korean clinical occupational therapists were conveniently sampled, the structured 293 questionnaires were released, the answered 293 questionnaires were analyzed. Results : Awareness of OBP was 5.7 points on average and the awareness, increased with age and clinical experience. The opportunity that Occupational Therapists know OBP was through major subjects, articles & seminars, through peers and so on. The differences depended on age, level of education, location of work, clinical experience. 152 Occupational therapists(52.8%) answered that they apply OBP in their clinical work. There was no significant difference in the use of OBP based on gender, age, clinical experience, education background with exception of work location. It was shown that during practice,The most frequently used OBP was as follow in order: interview, practice, goal setting, assessment and documentation. The goal of using OBP was to find out a meaningful occupation for client's living, to promote client's participation in family or community, to treat for function recovery of clients. The biggest difficulty faced during OBP was lack of understanding of OBP for the clients and their guardian. Other difficulties were limitations of treatment environment, lack of occupational instruments, related knowledge, utilization method, preparation time and difficulty in handling insurance and medical expenses in order. Conclusion : Level of awareness of OBP was at intermediate level and it was related to education level and treatment environment. Based on this result, it is need to support institutional and academical discusstion in order to promote OBP.

Objectives : Attention-deficit hyperactivity disorder(ADHD) is characterized by significant impairments in executive functions, with a prevalence of approximately 3-5% of all children worldwide. The goal of this study was to examine the relationship between executive functions and electrophysiological activities in children and adolescents with ADHD. Methods : In 31 patients with ADHD, resting-state EEG was recorded, and Comprehensive Attention Test(CAT), Stroop Color-Word Inference Test(Stroop CWIT), Trail Making Test(TMT), and Wisconsin Card Sorting Test(CST) were administered. Korean version of the ADHD Rating Scale(K-ARS) was assessed. Results : Alpha and beta power positively correlated with the Attention Quotient(AQ), while delta power negatively correlated with AQ from CAT. In the Stroop CWIT, decreased delta power and increased beta power were related to higher performance. Power of the alpha band increased with higher TMT performance. Moreover, delta power negatively correlated with good performance on the CST, while alpha and high gamma band showed a positive correlation. Correlation with the parent-rating of ADHD symptoms showed a negative correlation between alpha power and higher scores on the K-ARS. Conclusions : These findings indicate that relative power in higher frequency bands of EEG is related to the higher executive function in children and adolescents with ADHD, while the association with the relative power in lower frequency bands of EEG seem to be vice versa. Furthermore, the findings suggest that QEEG may be a useful adjunctive tool in assessing patients with ADHD.
