The introduction of Connected and Automated(CAD) technology has a growing interests especially in areas with low demand for transport, where often the local transport services do not connect to peripheral areas for more efficient and convenient mobility services. However, there are few researches on CAD-based mobility services in areas with low demand for transport. Because current researches are mainly focuses on introduction of CAD-based mobility services in area with high demand for transport such as urban and highway. These two areas have different road environments and these differences require different driving technology especially related to Operational Design Domain(ODD). ODD is important factors for introduction of CAD-based mobility services. Therefore, we compare the road environments of areas with low demand for transport and areas with high demand for transport in terms of ODD. In addition, this paper proposes suggest guidance for the introduction of CAD-based mobility services in areas with low demand for transport such as rural and suburban areas.

It can be said that the low birthrate problem is the common issue for all mankind. That is to say, not only South Korea but also many developed countries are facing the challenge associated with the low birthrate problem in line with an aging society. Just a few decades ago, the population control policy (the so-called “birth control” policy) was a top policy priority for many governments all around the world. However, the recent change in the population structure led by the decreasing young population and the growing elderly population will likely cause many serious problems at the national level in the future. On that account, many efforts are being made to encourage childbirth. In particular, the Korean government has been seeking for diverse measures to address the low birthrate problem since long ago. These measures include the childcare policy. However, the Korean government has yet to see the full effect of these measures albeit its massive spending on the facilities and systems for infants. Currently, the governmental departments have established and implementing their respective relevant statutory provisions in relation to the infant support projects. However, these legal systems have a different policy goal, thereby causing conflicts between the governmental departments. To make matters worse, similar projects are conducted redundantly; thus, a large portion of the government budget is wasted on the unnecessary expenses. Hence, it is necessary to mediate between the governmental departments by taking the details of support projects and the similarities thereof. In particular, the rapidly expanding free childcare policy has caused the problem of budget deficit. Currently, the central government and the local governments are fiercely disputing over the Nuri-Curriculum budget issue. The more important issue is that those children of vulnerable social group such as children with disabilities and children of near poverty group, who had not had any problem with receiving benefits before the implementation of free childcare, are now suffering directly from the aforementioned dispute between the central government and local governments. Germany recently found it appropriate to promote actual equality through the expansion of public facilities rather than simply providing financial support such as parenting allowance on the basis of the recent decision of its Constitutional Court. Japan is making efforts to prevent redundant projects and make the financial support more efficient by integrating the financial aspects and project implementation issues into a single low. This article examined diverse problems from a legal aspect as to Korea`s childcare policies. Moreover, this article reviewed the constraints and problems associated with the current Nuri-Curriculum and free childcare policy. Lastly, this article studied the improvement measures on the basis of the similar cases in Germany and Japan.

본 연구는 사회적·환경적 요인들에 의해 변화되고 있는 주거공간과의 상관관계를 분석하여 주거 트렌드를 파악하고, 그 특성들을 도출하고자 한다. 이를 바탕으로 다변화된 1인 세대들의 새로운 주거타입을 제안하였다. 또한 1인 가구가 가장 많이 거주하는 서울시 관악구 대학동을 대상지로 선정하여 제안하는 주거 유닛들을 바탕으로 설계대상과 프로그램을 선정하여 다양한 프로그램들과 1인 주거에 특화된 주거지를 계획하고자 한다. 1인 가구에 특화시키기 위해 ‘독립형’, ‘부분 공유형’ ‘공유형’, ‘직주 결합형’ 주거유닛 4가지의 주거형태를 제안하였다. 각 유닛은 공간의 공유 정도에 따라 유형이 나눠지고, 나눠진 유형에 따라 연관될 수 있는 프로그램들을 배치하여 각 유닛에서 공간의 다양성을 부여하고자 했다. This study analyzes the correlation with residential space being changed by social and environmental factors to identify residential trends and derive characteristics. Based on this, the government proposes a new type of housing for the diversified single-person generation. In addition, the government plans to select targets and programs based on the housing units proposed by selecting Sillim-dong, Gwanak-gu, Seoul, where the largest number of single-person households reside, to plan various programs and residential complexes specialized in single-person housing for them. In particular, Sillim-dong proposed a housing plan with its own spatial characteristics, suggesting that the residential space in architecture is also facing a new paradigm and changing in a diversified society, and is expected to be used as an example for future single-person household housing plans.

QoS 스케줄링 알고리즘을 위한 지분 분포의 효과 분석

김아름(AhReum Kim),정진만(Jinman Jung),홍지만(Jiman Hong) 한국정보과학회 2012 한국정보과학회 학술발표논문집 Vol.39 No.1A

응용 프로그램의 QoS를 보장하기 위하여 태스크들에게 지분을 부여하고 단위 시간동안 각 태스크에게 주어진 지분만큼의 CPU 자원을 할당하는 비례 지분 알고리즘들이 많이 연구되었다. 대부분 비례 지분 알고리즘들은 태스크 수, 지분 분포 등의 다양한 환경에 따라 동작 방식이 다르기 때문에 이러한 인자들은 시스템의 공정한 자원 할당에 많은 영향을 준다. 본 논문에서는 비례 지분 알고리즘을 동작 방식에 따라서 분류한 후, 태스크의 수와 더불어 지분의 편향성, 즉 지분 분포에 따라 QoS 공정성 결과를 분석한다. 분석결과, 비례 지분 알고리즘에서는 태스크의 수 뿐 만 아니라 지분의 분포 역시 QoS 공정성에 많은 영향을 주며, 각 환경에 따라 효율적인 최적의 알고리즘들이 존재함을 확인하였다. 제안된 분석 결과는 QoS를 지원하는 다양한 시스템에서 효율적인 비례 지분 알고리즘을 선택하여 시스템의 신뢰성을 향상시킬 수 있다.

OpenACC와 GPU를 이용한 3차원 파동 전파 모델링

김아름 ( Ahreum Kim ),이종우 ( Jongwoo Lee ),하완수 ( Wansoo Ha ) 한국지구물리·물리탐사학회 2017 지구물리와 물리탐사 Vol.20 No.2

We calculated 3D frequency- and Laplace-domain wavefields using time-domain modeling and Fourier transform or Laplace transform. We adopted OpenACC and GPU for an efficient parallel calculation. The OpenACC makes it easy to use GPU accelerators by adding directives in conventional C, C++, and Fortran programming languages. Accordingly, one doesn`t have to learn new GPGPU programming languages such as CUDA or OpenCL to use GPU. An OpenACC program allocates GPU memory, transfers data between the host CPU and GPU devices and performs GPU operations automatically or following user-defined directives. We compared performance of 3D wave propagation modeling programs using OpenACC and GPU to that using single-core CPU through numerical tests. Results using a homogeneous model and the SEG/EAGE salt model show that the OpenACC programs are approximately 53 and 30 times faster than those using single-core CPU.

완벽주의와 정서강도, 정서 인식 명확성에 따른 하위집단과 정신건강

김아름(Kim, AhReum),이지연(Lee, JeeYon) 한국열린교육학회 2011 열린교육연구 Vol.19 No.1

본 연구는 수도권 대학생 246명을 대상으로, 완벽주의, 정서강도, 정서인식 명확성의 조합에 따라 어떤 자연발생적인 하위집단이 형성되며 각 하위집단 간 정신건강 차이가 어떠한지를 알아보기 위해 수행되었다. 이에 완벽주의, 정서강도, 정서인식 명확성을 중심으로 2단계 군집분석을 실시한 결과, 정서인식 명확성에서는 집단간 차이가 유의미하지 않아 완벽주의의 두 차원인 사회부과 완벽주의와 자기지향 완벽주의, 그리고 정서강도에 따라 4집단(범완벽주의 평균정서 집단, 사회부과 완벽주의 강렬정서 집단, 비완벽주의 무딘정서 집단, 자기지향 완벽주의 민감정서 집단)으로 구분되었다. 이 중 사회부과 완벽주의가 높으면서 정서를 강렬하게 느끼는 집단이 정신건강상 어려움이 많았고 자기지향 완벽주의가 높으면서 정서에 민감한 집단의 정신건강이 가장 양호했다. 이런 결과를 토대로 본 연구의 시사점과 제한점, 그리고 앞으로의 연구방향에 대한 시사점을 언급하였다. This study examined individual differences in perfectionism and emotional variables, such as Socially Prescribed Perfectionism(SPP), Self-Oriented Perfectionism(SOP), Affect Intensity(AI) and Emotional Clarity(EC), and their characteristics in psychological adjustment. According to cluster analysis, emotional clarity is not significant enough to distinguish each group. Thus, the combination of the other three variables, Socially Prescribed Perfectionism, Self-Oriented Perfectionism, and Affect Intensity, drawn from 246 college students formed four clusters. "The General Perfectionism and average affect group" is characterized by the highest scores on Socially Prescribed Perfectionism and Self-Oriented Perfectionism, together with an average score on Affect Intensity, compared to other groups. The "Socially Prescribed Perfectionism and intense affect group" is characterized by a higher score on Socially Prescribed Perfectionism compared to other groups, combined with the highest score on Affect Intensity and the lowest score on Self-Oriented Perfectionism. By contrast, "Self-Oriented Perfectionism and sensitive affect group" is characterized by a lower score on Socially Prescribed Perfectionism and a higher score on Self-Oriented Perfectionism, Affect Intensity in relation to other groups. Finally, "Non-Perfectionism and cool affect group" is characterized by the lowest score on Socially Prescribed Perfectionism and Affect Intensity, together with a lower score on Self-Oriented Perfectionism compared to other groups. The cluster analysis along with MANOVA results, suggest the four groups significantly differ in their score across psychological symptoms. Among four groups, Socially Prescribed Perfectionism and intense affect group reveals the most elevated symptoms, especially somatization disorder, obsessive-compulsive disorder, anxiety and paranoid ideation, which indicates that this group would experience more psychological distress.

그래픽 프로세서를 이용한 시간 영역 3차원 파동 전파 모델링과 메모리 관리

김아름 ( Ahreum Kim ),류동현 ( Donghyun Ryu ),하완수 ( Wansoo Ha ) 한국지구물리·물리탐사학회 2016 지구물리와 물리탐사 Vol.19 No.3

We used graphics processing units for an efficient time-domain 3D wave propagation modeling. Since graphics processing units are designed for massively parallel processes, we need to optimize the calculation and memory management to fully exploit graphics processing units. We focused on the memory management and examined the performance of programs with respect to the memory management methods. We also tested the effects of memory transfer on the performance of the program by varying the order of finite difference equation and the size of velocity models. The results show that the memory transfer takes a larger portion of the running time than that of the finite difference calculation in programs transferring whole 3D wavefield.

소지역 추정은 표본 크기가 작은 소지역이나 성별, 연령 등과 같은 변수의 특성으로 분류된 영역에 대한 통계치를 산출할 경우 표본의 수가 적어 정확한 추정이 힘들 때 이용되는 통계적 추정 방법의 하나다. 소지역 추정은 다양한 통계적인 생산에 필수적이며, 다양한 방법으로 연구되어왔다. 소지역추정방법 중 하나인 모형기반 추정 방법은 회귀분석, 공간분석 등과 같이 방법들을 고려할 수 있다. 본 연구에서는 소지역 추정을 위해서 변량효과를 고려한 다단계 일반화 선형모형을 적용하였다. 이때. 변량효과에 대한 모형가정을 정규분포, 감마분포 등 다양한 분포를 적용하였으며, 모형선택 방법을 통해서 자료에 가장 적합한 모형을 선택하였다. 분석 결과를 활용하여 행정동 단위의 소지역을 분류하는 방법을 먼저 보여주고 지역간 모형 적합 결과를 비교하고자 한다. 이를 위해 수집된 부산지역 암등록 자료 236,277건에 대해 행정동 분류를 완료했으며, 이 자료 중 위암인 경우를 선택하여 성별, 병기별로 다단계 일반화 선형모형에 적합하였다. 또한, 변량효과의 분포 및 박탈지수의 여부에 따라 적합도가 달라졌으며 박탈지수가 지역내변동을 설명할 수 있다는 것을 확인하였다. 모형 적합 결과 추정된 변량효과 추정치는 소지역간 변이를 나타내는 지표로 활용될 수 있을 것으로 기대된다. Small area estimation is one of the statistical estimation methods when accurate estimation is difficult due to the small number of samples with a small sample size. Small area estimation are necessary for various statistical production and have been studied in various ways. A model-based estimation method, one of the small area estimation methods, is based on parametric models like regression estimation, spatial estimation and so on. In this study, hierarchical generalized linear model with random effect was applied to major cancers like stomach cancer using two types of distribution of random effect in models, respectively. For distribution of random effect, Gaussain or gamma distributions are assumed. For this purpose, the method of classifying the data into small areas of the administrative unit was presented first, and then the results of the model fitting were compared by region. We expect that the estimated random effect from the fitted model can be used as an indicator of small area variability.
