Objectives : The Self-Assessment Manikin (SAM) developed by Bradley and Lang is a non-verbal pictorial assessment tool that measures human emotion and has been widely used. However, the pictures in SAM have not been easy for Korean subjects to understand or relate to. The authors developed a new manikin (Emotional Valence and Arousal Manikin, EVAS) modeling it after Korean faces while modifying and standardizing the SAM. Methods : Forty-one healthy subjects participated in this study. They were asked to rate the emotional valence and level of arousal using both the SAM and EVAS after being exposed to pictures of facial expressions for affective neurosciences-Korean version. The internal consistency of the EVAS and the correlation between EVAS and SAM were examined. Resuts : Internal consistencies of the valence using the EVAS were from 0.63 (surprise) to 0.82 (happiness) and those of the arousal were from 0.90 to 0.95. Correlation coefficients of the valence and arousal between the SAM and EVAS were from 0.61 (both surprise and disgust) to 0.84 (neutral) and from 0.82 (sadness) to 0.94 (fear), respectively. Conclusions : We developed a new manikin (the EVAS) for the Korean population modifying and standardizing the SAM. The EVAS demonstrated a good internal consistency and validity. As such, it can be used in the field of human emotion research.

최근 들어 계속되는 램 가격 하락으로 인해 대용량의 램을 사용하는 주기억장치 데이터베이스 시스템의 구축이 실현 가능하게 되었다. 주기억장치 데이터베이스는 여러 다양한 실시간 응용 분야를 위해 사용되며, 매년 CPU 속도가 60% 정도 증가되고, 메모리 속도가 10% 증가되는 현실에서, 케쉬 미스(Cache miss)를 얼마나 줄이느냐 하는 문제가 주기억장치 데이터베이스의 검색 성능 측면에서 가장 중요한 문제로 대두되고 있다. 본 논문에서는 이러한 환경을 고려한 실시간 모바일 GIS응용을 위한 주기억장치 데이터베이스 시스템을 설계 및 구현한다. 본 시스템은 크게 PDA를 사용하는 모바일 사용자를 위한 인터페이스 관리기와 가상 메모리 기법을 사용해 전체 데이터를 주기억장치에 상주시키며 관리하는 주기억 데이터 관리기, 공간 및 비 공간 질의를 처리하는 질의처리기, 새롭게 제시하는 공간 데이터를 위한 MR-트리 인덱스와 비 공간 데이터를 위한 T-트리 인덱스 구조를 관리하는 인덱스 관리기, 데이터를 디스크에 저장하기 위한 GIS 서버 인터페이스로 구성된다. 새롭게 제시하는 공간 인덱싱을 위한 MR-트리는 노트 분할이 발생될 경우, 입력 경로 상에 하나 이상의 빈 엔트리를 지니는 노드가 존재할 경우에만, 노드 분할을 상위로 전송한다. 그러므로 중간 노드들은 항상 100%에 가깝게 채워져 있게 된다. 본 논문의 실험 결과, 2차원의 MR-트리는 기존의 R-트리에 비해 2.4배 이상의 빠른 검색 속도를 나타냈다. 한편, 주 기억 데이터 관리기는 가상 메모리 제공을 위해 전체 벡터 데이터 및 MR-트리, T-트리, 데이터 객체 텍스트 정보를 페이지 단위로 분할하여 관리하고, 간접 주소 기법을 사용하여 디스크로부터의 재 로딩시 발생할 수 있는 문제점을 제거하였다. As random access memory chip gets cheaper, it becomes affordable to realize main memory-based database systems. Consequently, reducing cache misses emerges as the most important issue in current main memory databases, in which CPU speeds have been increasing at 60% per year, compared to the memory speeds at 10% per you. In this paper, we design and implement a main-memory database system for real-time mobile GIS. Our system is composed of 5 modules: the interface manager provides the interface for PDA users; the memory data manager controls spatial and non-spatial data in main-memory using virtual memory techniques; the query manager processes spatial and non-spatial query : the index manager manages the MR-tree index for spatial data and the T-tree index for non-spatial index : the GIS server interface provides the interface with disk-based GIS. The MR-tree proposed propagates node splits upward only if one of the internal nodes on the insertion path has empty space. Thus, the internal nodes of the MR-tree are almost 100% full. Our experimental study shows that the two-dimensional MR-tree performs search up to 2.4 times faster than the ordinary R-tree. To use virtual memory techniques, the memory data manager uses page tables for spatial data, non- spatial data, T-tree and MR-tree. And, it uses indirect addressing techniques for fast reloading from disk.

Sleep disorders such as insomnia, obstructive sleep apnea (OSA), and restless legs syndrome (RLS) are very common disorders and may cause significant burden in terms of individual as well as societal aspects. Sleep insufficiency from such sleep disorders may cause deleterious effects on daily work life and may be associated with other major medical or psychiatric disorders including cardiovascular disease, diabetes mellitus, depression, and anxiety disorder. Various motor or occupational accident may result from the sleep problems. In addition, recent researches provide the method to evaluate the lost productivity time in terms of absenteeism and presenteeism. Moreover, several studies on cost-effectiveness of treatment of sleep disorders show that it is cost-effective.

This research paper examined the variation in solar irradiance quantitatively over time by comparing solar irradiance data from domestic Typical Meteorological Year (TMY) records. Solar radiation can produce different TMY records depending on the year of data collection, even for the same region. Therefore, simulation users should take these factors into consideration and select appropriate TMY records based on their specific needs. The results showed that the recently produced TMY records had higher solar irradiance values than those produced in the past. The average annual deviation between different TMY records was 86.1 kWh/㎡yr (6.5%). However, a comparison of TMY records from KIRE and SAREK, which have a significant difference in publication date, demonstrated that the deviation increased to an average of 204 kWh/㎡yr (14.4%), with a maximum of kWh/㎡yr (16.9%). The study also found that the difference in solar irradiance is related to the ratio of direct solar radiation when converting GHI to inclined plane irradiance. The annual cumulative solar irradiance showed significant variations on the southern inclined planes with a high ratio of direct solar radiation, while minimal changes were observed on northern inclined planes with a high ratio of diffusion solar radiation.

Considering the values acquired from thermal bridge performance indicators developed based on a design stage may differ from the actual thermal bridge performance values, it is essential to quantitatively assess their performance in-situ. When the surface temperature of the internal walls of a thermal bridge is measured in-situ to evaluate the performance, a time delay is observed in the transfer of the effect of external conditions to the internal surfaces. The shape of the thermal bridge components exhibit either 2D or 3D boundary conditions, and hence, multiple time lags can occur depending on the surface condition of the thermal bridge, which affects the accuracy of the performance of thermal bridges during evaluations in-situ. Therefore, in this study, we analyzed the effect of time lag of the thermal bridge components on the thermal bridge performance using heat transfer simulations. It was observed that the relative error was approximately 25.35% with an average of 9.22% as compared to the steady-state thermal bridge. Furthermore, the approximate time lag values of each component surface were calculated based on their surface temperatures. As a result, the time lag difference between the thermal and non-thermal bridge components was approximately 10 h and 30 min, respectively. On eliminating the time lag difference from all surfaces of the thermal bridge components using the calculated time lag, the relative error decreased to 19.97% with an average of 7.69%, as compared to the steady-state thermal bridge. Therefore, the relative error increased by 1.53% with an average of approximately 5.40%, owing to the time lag of the thermal bridge.

Most modern researches have focused on the underlying biological mechanisms as the basis of various psychopathology such as psychosis, depression, anxiety, etc. However, little is known about the biological basis of positive psychology. Recent developments in biological and neuroscientific techniques enable us to speculate that there are also biological basis in the field of positive psychology. The author introduces some important researches on the biological basis of positive psychology.

본 연구는 신체 증상을 호소하는 정상인들을 대상으로 3주간 홍삼 또는 위약을 투여하였고, 홍삼 복용군에서 위약 복용군에 비해 신체 증상 감소 정도가 더 큼을 보여주었다. Various somatic symptoms are known to be related to stress in a general population. Korean red ginseng has been used as a therapeutic agent for the treatment and prevention of many diseases in Oriental medicine. There exist no data, however, on the effect of Korean red ginseng on somatic symptoms in a general population. In this study, 21 normal subjects were randomly assigned to the Korean-red-ginseng group, and 18 subjects to the placebo group. The subjects took 3 g Korean red ginseng or placebo every day for three weeks. After the three-week treatment, there was a 〈time x group〉 interaction effect of a greater reduction in the Symptom checklist-90-revised (SCL-90-R) somatization score (p=0.04) in the Korean-red-ginseng group. This study suggests that Korean red ginseng is effective for the management of somatic symptoms in a general population.

발열유리 시스템 적용 건물의 열쾌적 제어를 위한 MRT 추정 모델 단순화 및 검증

발열유리와 같은 위한 복사난방 시스템을 이용하여 해당 공간의 평균복사온도(MRT; Mean Radiant Temperature)를 제어하기 위해서 해당 공간의 MRT를 관측하여야 한다. 표면온도를 이용하여 MRT를 얻기 위해 공간 내 모든 표면온도를 활용하는 것이 가장 정확하겠지만, 실내측 표면들은 유사한 경계조건 상에 놓여 있기 때문에 일부 표면을 제외하고는 비슷한 열적거동을 보일 수 있다. 따라서 다수의 표면온도로 얻어진 MRT와 적은 표면온도들로 얻어진 MRT와 적은 차이를 보일 수 있다. 이에 따라 본 연구에서는 측정된 표면온도들을 군집화함으로써 MRT 추정에 필요한 입력변수를 단순화하고 이에 따른 추정 결과의 유효성을 검토하고자 한다. 연구방법은 측정 실험을 통해 MRT 추정 모델을 수립하고 모델의 입력변수를 줄여나감에 따른 오차의 변화를 검토함으로써 진행된다. 측정 실험 결과, MRT 추정 모델의 오차는 평균 0.32℃ 최대 0.6℃로 나타났다. 이후 유사한 데이터끼리 군집화하여 계산에 필요한 표면온도 개수를 줄여 MRT를 도출하였다. 2개 표면온도를 이용한 MRT와 3개 표면온도를 이용한 MRT는 유의미한 차이를 보였으나 4개 이상의 표면온도 입력부터는 오차감소가 작게 나타나 추가 입력데이터에 따른 오차개선이 크지 않는 것으로 나타났다.
