The purpose of this study is to investigate the effects of mindfulness training with psychological techniques in a professional archery team in South Korea. First of all, it is conducted to find the changes in mindfulness through the KIMS during the mindfulness training, and to analyze the changes in both mindfulness and psychological technique factors. After ten times of meditation (1h-1h30m/1d), ACT and MAC based on the mindfulness training program, there were significant positive influences of psychological factors such as techniques, acceptance, concentration behavior and attention behavior on an intervention group compared to a control group, resulting in KIMS. Although there were no significant differences in confidence and teamwork in the intervention group after the psychological techniques, there were positive effects on willpower, goal setting , concentration, anxiety control and imagery statistically in the intervention group. In conclusion, mindfulness training has positive effects on the mindfulness in Korean archers. This training also has a positive influence on psychological technique factors such as attention, imagery, concentration and anxiety control. According to previous literatures, it is proved that there were positive effects on the psychological technique factors with the changes in mindfulness. Therefore, it is required to develop tools which can measure the mindfulness and to apply the correlation of mindfulness and psychological techniques to the field.

대용량의 데이터가 저장되는 데이터 웨어하우징 환경에서 조인이나 집계 함수와 같은 고비용의 연산의 효율적인 처리는 매우 중요하다. 본 논문에서는 집계 함수(aggregate function)와 조인(join)이 모두 포함된 질의를 처리하는 새로운 기법을 제안한다. 제안하는 기법은 먼저 차원 테이블(dimension table)을 미리 그루핑한 후, 비트맵 조인 인덱스(bitmap join index)를 이용하여 조인을 처리하는 방식을 사용한다. 이 결과, 사실 테이블(fact table)만을 접근하여 집계 함수를 처리함으로써 기존 기법이 가지는 성능 저하의 문제점을 해결할 수 있다. 기존 기법과 제안하는 기법에 대한 비용 모델(cost model)을 정립하고, TPC-H 벤치마크를 기반으로 하는 다양한 시뮬레이션을 수행함으로써 제안된 기법의 우수성을 규명한다. Efficient processing of expensive queries that include joins and/or aggregate functions is crucial in data warehousing environment since there reside enormous volume of data. In this paper, we propose a new method for processing of queries that have both of joins and aggregate functions. The proposed method first performs grouping of the dimension table and then processes join by using the bitmap join index. This makes only the fact table accessed for processing aggregate functions, and thus resolves the serious performance degradation of the existing method. For showing the superiority of the proposed method, we suggest the cost models for the proposed and existing ones, and perform extensive simulations based on the TPC-H benchmark.

This study has been carried out to understand the effect of Danchisoyosangagambang (DC) on the hyperglycemic mice induced with streptozotocin(STZ). Experimental groups were made diabetic mice by intraperitoneal injection of STZ(60 mg/kg of body weight) tw ice by 24 h interval and then 120 mg/kg STZ was injected again 3 days after the earlier treatment. Control group was administered mice with 0.9 % saline(2 mL/kg), and experim ental groups were administered DC extract(DCA group, 10 mg/kg/day; DCB group, 30 mg/kg/day) after hyperglycemic induction for 6 weeks. The body weight of experimental groups was lower than control. The blood glucose concentration increased continuously, rea ching to 298.9 mg/dL after 6 weeks, however, experimental groups of the DCA and DCB groups significantly(p<0.0l) decreased in the 4, 5, and 6 weeks groups. Blood glucose tolerance test was not significant between control and experimental groups. We examined the blood transaminase activities to know the effect of herbal medicine on liver function. The GOT activities were lower in group DCB than in control. The GPT activities were lower in group DCA and DCB than in control. The content of triglyceride was significantly increased in group DCA compared to control. The SOD and catalase activities were higher in the group DCA compared to control. The results of immunohistochemical study, a few of insulin positive cells observed in the control and experimental group. These results suggest that administration of DC extract to the hyperglycemic mice decreased the blood glucose level.

Residence time is defined as the time taken for a material in a system to leave the system. The residence time characteristics in shellfish aquaculture determine the dispersion of excretion from aquaculture farms, along with the supply of food by seawater exchange. In this study, we estimated the spatial distribution of average residence time in the shellfish farming area using a particle tracking model. As a result, a relatively short average residence time of about 20 days or less was calculated in most areas, but an average residence time of more than 40 days was calculated in the inner areas. Relatively long average residence times were calculated along the west coast compared to the east coast, with the longest average residence time of more than 50 days in the northwestern areas. It can be inferred that the disturbance of the benthic ecosystem caused by shellfish farms is likely to be large because of the relatively weak dispersion of excrement from shellfish farms located on the west coast, especially in the northwest region. This distribution of average residence time is important for understanding the potential effects of seawater exchange on the environmental sustainability of shellfish farms, along with the seawater circulation characteristics of Jaran Bay.

This paper proposes a method to measure the airburst height by utilizing a high speed camera. This method might be applied to the test of which flight target is alive after the burst. The proposed method consists of four main steps. The first step is to compute the impact point using the sea surface height. The second step is to compute the height of burst (HOB) by using the distance from the camera to the impact point. This could be different from the real explosion height. That is because the distance from the camera to the burst point is not the same as it from the camera to the impact point. Therefore, the third step is to calculate the approach angle of the flight target with respect to the installed camera. Then, the last step is to compensate the computed height by using the approach angle. The result of the proposed method is compared with it from the triangulation. In this paper, the HOB error is also analyzed regarding the approach angle difference. Based on this analysis, the camera position might be suggested for error reduction.

피라미드 기법은 n-차원 공간 데이터를 1차원 데이터로 변환하여 B+-트리로 표현하며, n-차원 데이터 공간에서 하이퍼큐브 영역질의 처리로 발생하는 “차원의 저주현상”에 영향을 받지 않게 검색 시간 문제를 해결하고 있다. 또 구형 피라미드 기법(SPY-TEC)은 피라미드 기법의 공간 분할 전략을 응용하여 유사도 검색에 적합한 구 영역질의 방법을 사용하고 검색 성능을 개선하고 있다. 하지만 유사도 검색의 응용에서 영역질의는 범위를 지정하는데 어려움이 있어 최근접 질의가 더 효율적이며, 기존의 제안된 인덱스 기법들은 특정 분포의 데이터에 대해서만 우수한 성능을 보이는 단점이 있다. 따라서 이 논문에서는 멀티미디어 데이터와 같은 고차원 데이터의 검색 성능을 향상시키기 위해 제안되었던 PdR-트리를 이용하여 최근접 객체 검색 기법을 제안한다. 다양한 분포의 모의 데이터와 실제 데이터를 이용하여 실험한 결과, PdR-트리가 피라미드 기법과 구형 피라미드 기법보다 검색 성능이 향상되었음을 보이고 있다. The Pyramid-Technique is based on mapping n-dimensional space data into one-dimensional data and expresses it as a B+-tree. By solving the problem of search time complexity the pyramid technique also prevents the effect of "phenomenon of dimensional curse" which is caused by treatment of hypercube range query in n-dimensional data space. The SPY-TEC applies the space division strategy in pyramid method and uses spherical range query suitable for similarity search so that Improves the search performance. However, nearest neighbor query is more efficient than range query because it is difficult to specify range in similarity search. Previously proposed index methods perform well only in the specific distribution of data. In this paper, we propose an efficient searching technique for nearest neighbor object using PdR-Tree suggested to improve the search performance for high dimensional data such as multimedia data. Test results, which uses simulation data with various distribution as well as real data, demonstrate that PdR-Tree surpasses both the Pyramid-Technique and SPY-TEC in views of search performance.rformance.
