패시브하우스는 주거공간에 필요한 공기량을 단지 신선한 외부의 공기만을 데우거나 식힘으로 실내 열적 쾌감을 만족 시킬 수가 있는 건물을 말한다. 이 정의는 단지 기능적인 표현이며 어떠한 절대적 수치를 포함하지 않으며 어떤 기후에도 적용된다. 패시브하우스 용어의 선택은 임의적으로 지어진 것이 아니라 건물의 계획과 사용에 있어서 최대한 간접적인 수단으로 열적 쾌적함이 이뤄 질수 있도록 노력하는 것이며, 직접적인 수단은 최소화 시키는데서 이루어진 것이다. 직접적인 수단은 단지 꼭 필요한 것과 필요한 곳에 한정해 최소화 시키는 것이 궁극적인 목적이다. 이러한 패시브하우스 도입은 온실가스 감축, 고유가 등 환경변화에 대응하기 위한 것으로 디자인에서부터 자재사용까지 전 과정에 걸쳐 이뤄지고 있다. 본지는 국내에 적용 중이거나 적용할 예정인 패시브하우스에 대해 알아본다.

본 논문에서는 멀티미디어 프리젠테이션 과정에서 발생할 수 있는 여러 동기화 요소를 고려한 프리젠테이션 제어 방안에 대하여 기술하였다. 효율적인 프리젠테이션을 위하여 모노 미디어의 개별적인 효과 표현과 시나리오를 기반으로 한 스케줄러, 그리고 여러 하드웨어 및 소프트웨어 관리 쓰레드 등으로부터 동기화와 직.간접적으로 관련된 이벤트를 발생시키고 이러한 이벤트를 종합적으로 관리하도록 하였다. 발생된 이벤트는 불규칙하고 동시다발적이기 때문에 발생 환경에 따라 적절하게 폐기하거나 처리의 선후관계를 다시 정의하는 등 프리젠테이션 환경에 따른 최적의 서비스 품질을 유지할 수 있도록 고려하였다.

This study explored the relationship between children's emotional competence, aggression and peer relationships. Participants were 164 third and 134 fourth grade children from five elementary schools in Seoul and Chenan. Emotional competence, aggression and peer relationships were assessed by means of a questionnaire, interview and observation. Results indicated that emotional understanding of self and others, sex, age, emotional expression and passive regulation strategies were significant variables in predicting children's aggression. Emotional understanding was the most predictable variable in relation to peer relationships. Emotional understanding, emotional regulation and emotional expression made independent contributions to aggression and peer relationships. Mediation analyses revealed that the significant connections between children's emotional competence and negative peer relationships were mostly mediated by aggression.

그래프를 사용하는 데이터 표현법은 직$\cdot$간접적으로 실세계를 표현하는 다양한 데이터 모델 중에서 가장 일반화된 방법으로 알려져 있다. 기본적으로 그래프는 정점과 간선으로 구성되며, 정점과 간선은 그 중요도나 운영 목적에 따라 다양한 가중치가 부여될 수 있다. 특히, 이러한 그래프를 순회하는 트랜잭션들로부터 중요한 순회패턴을 탐사하는 것은 흥미로운 일이다. 본 논문에서는, 정점과 간선에 가중치가 있고 방향성을 가진 기반 그래프가 주어졌을 때, 그 그래프를 순회하는 트랜잭션들로부터 가중치를 고려하여 빈발 순회패턴을 탐사하는 방법을 제안한다. 또한, 이렇게 탐사한 결과에 가중치를 고려한 중요도를 평가하여 빈발 순회패턴들 간의 우선순위를 결정할 수 있도록 한다. 이 과정에서 발생할 수 있는 트랜잭션 노이즈는 기반 그래프의 간선 가중치의 평균과 표준편차를 이용하여 제거함으로써 보다 신뢰성 있는 빈발 순회패턴을 탐사할 수 있다. 제안한 논문은 웹 로그 마이닝 등 그래프를 이용하는 다양한 응용 분야에 적용할 수 있을 것이다.

최근 연구되고 있는 XML 문서를 위한 접근 제어에 관한 연구는 간접적으로 접근 권한을 표현하는 명세 기반 접근 제어 방법과 각 객체에 직접적인 접근 권한을 표현하는 속성 기반 접근 제어 방법으로 구분할 수 있는데, 명세 기반 접근 제어 방법은 공간 효율적이며, 속도 비효율적인 특성을 갖으며, 속성 기반 접근 제어 방법은 속도 효율적이며, 공간 비효율적인 특성을 갖는다. 또한 이러한 연구의 초점은 안전한 접근 제어를 보장하면서, 부가적인 비용 증가를 줄이고자 하지만, 대부분의 연구에서는 인덱스 기법에 기반 하지 않고 문서 전체 또는 일부를 액세스 하므로 탐색 비용 또는 데이터 처리 비용이 증가하고, 특정 기법에 국한 하여 적용하기 때문에 각 기법이 갖는 근본적인 문제점온 해결 할 수 없다. 따라서 이러한 문제점을 해결하기 위해 인덱스 기반의 전역 접근 제어와 지역 접근 제어 메커니즘 제안하고. 이률 기반으로 명세/속성 기반 접근 제어를 연계하여 강제 접근 제어(MAC)의 최소 접근 권한 정책을 지원하는 역할 기반 다중 레벨 접근 제어 모델에 적용하였다.

As an interest in metaverse increases, there are many studies to apply virtual reality to indirect experiences. Virtual reality is increasingly being used not only for entertainment such as games but also for educational content. A key technology of indirect experience is modeling an object to provide a realistic experience to the user. Natural environments such as tidal flats change with time, and many living things also live there. In this paper, we propose a method for creating experiential content that accurately models the ecological environment of tidal flats. The proposed method explains how to naturally model the temporal change of tidal flats. We also explain how to model a crab, a creature that inhabits the tidal flat, in the forms of an NPC using the behavior tree. Implementation results show that the proposed method uses simple algorithms but expresses the shapes of tidal flats well.

Brandom upholds the anaphoric theory of reference. On this theory, reference is a relation of anaphoric dependence between linguistic items rather than a substantial relation between linguistic items and non-linguistic objects. In addition, 'refers' is a pronoun-forming operator, which is used to form anaphorically indirect descriptions such as 'the one referred to as "Leibniz"'. Recently, Arbid $B{\aa}ve$ raises three objections against this theory. First, the anaphoric theory distinguishes between ordinary descriptions and anaphorically indirect descriptions in terms of iterability. But this condition is not an adequate ground for asserting that anaphorically indirect descriptions form a distinctive semantic category. Second, sentences containing a pronoun such as 'he' and sentences containing an anaphorically indirect description such as 'the one referred to as "Leibniz"' have different modal statuses. Consequently, indirect descriptions are semantically different from paradigmatic anaphors. Third, on the anaphoric theory, expressions of the form 'a' and the corresponding indirect descriptions of the form 'the one referred to as "a"' are intersubstitutable. But we can make an equivalent claim by using the more general semantic concepts such as equivalence and intersubstitutability, instead of using notions such as 'anaphor' and 'antecedent'. So the anaphoric theory is explanatorily idle. In this paper I argue that these objections do not pose a serious problem for the anaphoric theory of reference. I argue thereby that the anaphoric theory of reference is a promising theory which provides us with the right understanding of the expression 'refers'.

In Korea, Pbichim refers to a psychological state caused by emotional damages that can occur within close relationships. In this state, one might feel reluctant to express one's feelings directly to the other party. It is also possible that Pbichim transforms into anger. This study is aimed to define the term Pbichim as an indigenous psychological concept. In Korea, it is common to express one's feelings indirectly and read the other party's inward thoughts. Pbichim reflects those cultural aspects. In order to examine the representation of Pbichim in Korea, we developed a questionnaire consisting of 15 open-ended questions. The participants were 119 undergraduate and graduate students at Korea University, and the data was analyzed qualitatively. As a result, four different aspects of Pbichim (unsatisfied expectation, being ignored, being alienated, and power struggle) could be differentiated by the situation in which people are likely to present Pbichim. The personality traits of Pbichim, the way of relieving it, as well as positive and negative functions of Pbichim were also elicited. In addition, it was found that Pbichim (the concept that has been negatively perceived) has an important function in maintaining and improving an interpersonal relationship in Korea. Lastly, the importance of mind reading within a certain cultural context is discussed.

For realistic rendering volume to calculate the light effects as well as the shade is essential. In order to produce the high quality of the resulting image, it is necessary to represent a global illumination, and it should be considered an indirect effect of the direct impact and scattering of light. It requires a lot of resources in order to perform this operation and, in particular, is very expensive when large amounts of data to be rendered as a volume data is consumed. In this paper, we generate a scatterer template according to the physical laws for each material. Considering that each object having material property stores photons of the template based on the Lambert illumination model. When the volume rendering in this paper, using the photon is stored in the template, based on the voxel to be sampled within the examination volume occluded, and it represents the global illumination of the scattering. Because the materials produced by the template requires a less resource only if comprised of a complex material, a simple operation can be expressed within the scattering volume at a low cost through.

The aim of this research was to verify the mediating effects of ambivalence over emotional expressiveness and distress tolerance on the relationship between harm avoidance and depression. A total of 403 university students completed TCI-RS(Temperament and Character Inventory-Revised Short version), AEQ-K(Ambivalence over Emotional Expressiveness Questionnaire-Korean), DTS (Distress Tolerance Scale) and CES-D(The Center for Epidemiologic Studies Depression Scale). The results revealed that harm avoidance and ambivalence over emotional expressiveness were positively related with depression, and negatively related with distress tolerance. In addition, the relationship of harm avoidance and depression was successively mediated by ambivalence over emotional expressiveness and distress tolerance. That is, the motivation of emotional expression conflict may have an effect on depression and the distress tolerance would play an important role in therapeutic intervention of depression.
