Objectives:This study aimed to compare anger coping strategies between bipolar I disorder and schizophrenia, and to explore the relationship between impulsivity and anger coping strategies. Methods:Forty three bipolar patients who met DSM-IV criteria for bipolar I disorder and forty three schizophrenia controls who were matched by age and sex were included. Anger coping strategies were measured by Anger Coping Scale(ACS), and the levels of impulsivity were also measured by Barratt Impulsiveness Scale(BIS). Independent t-test was used to compare anger coping strategies between two groups, and analysis of covariance(ANCOVA) to adjust the influence of impulsivity. Results:Score of problem-solving coping strategy was significantly higher in bipolar I disorder than schizophrenia (t=-2.047 p=.044). Problem-solving strategy was negatively correlated with total impulsivity in both bipolar patients and schizophrenic controls(bipolar I disorder r=-.376 p=.013 ; schizophrenia r=-.395 p=.009). There was no significant difference of problem-solving coping strategy between two groups after adjusting impulsivity(F=2.385 p=.126). Conclusion:These results suggested that bipolar I patients have a tendency to use more problem-solving coping strategy for anger situation than schizophrenia, which can be influenced by the level of impulsivity.

회전익기가 하강 비행 시 발생하는 와류 고리 상태는 회전면 근처에 도넛 모양의 순환유동을 발생시키며, 추력 상실로 인한 기체의 추락을 유발한다. 본 논문에서는 무인 비행체의 종류 중 하나인 쿼드콥터의 와류 고리 상태에서의 유동장을 물리적으로 규명하였다. 한국항공우주연구원 1m 아음속 풍동에서 쿼드콥터의 하강 비행을 모사했으며, 유동장 계측을 위해 입자 영상 유속계(PIV)를 이용했다. 정지 비행 상태의 유도 속도를 운동량이론을 이용하여 추정하고, 이를 통해 와류 고리 상태를 유발할 수 있는 하강 속도의 범위에서 시험을 수행하였다. 또한 하강률에 따른 유동장 계측뿐만 아니라 프로펠러 간의 간격을 달리 주어서도 와류 고리의 발달 및 진행방향을 확인하였다. 더불어 본 연구 결과는 쿼드콥터 주변의 유속 측정을 통해서도 와류 고리 상태를 예측할 수 있다는 것을 보여준다. The vortex ring state that occurs during the descending flight of a rotorcraft generates a circulating flow like a donut near the rotating surface, and it often causes a rotorcraft fall due to loss of thrust. In this paper, we have physically identified the flow field in the vortex ring state of the quadcopter, one of the types of unmanned aerial vehicles. The descending flight of the quadcopter was simulated in a 1m subsonic wind tunnel of the Korea Aerospace Research Institute(KARI) and the Particle Image Velocimetry(PIV) was used for the flow field measurement. The induced velocity in the hovering state is estimated by using the momentum theory and the test was carried out in the range of descent rate at which the vortex ring condition could be caused. The development and the direction of the vortex ring were confirmed by the measurement of the flow field according to not only the descent rate but also propeller separation distance. In addition, the results of the study show the vortex ring state can be predicted sufficiently by measuring the flow velocity around the quadcopter.

목적: 위선종 혹은 조기위암에 대한 치료로 내시경점막하박리술(ESD)이 널리 시행되고 있다. 그러나 시술 전 조직소견과시술 후 최종 진단의 불일치가 나타나는 경우가 있으며 일부에서는 시술 후 음성소견이 관찰되는 경우도 있다. 이에 이연구는 ESD 시행 후 병리학적 음성으로 판명된 환자를 대상으로 이의 원인에 대해 알아보고자 하였다. 대상 및 방법: 2007년 1월부터 2010년 1월까지 고려대학교 구로병원에서 위선종, 조기위암으로 ESD를 시행받은 환자 중시술 후 조직학적 음성을 보이는 환자를 대상으로 의무기록을 후향적으로 분석하였다. 결과: ESD를 시행받은 환자 792명 중 27명(3.4%)에서 음성 판정을 받았다. 대상환자의 시술 전 진단은 조기위암 11예 (40.8%), 저이형성 선종 13예(48.1%), 고이형성 선종 3예 (11.1%)였다. 병리학적 음성 예의 원인 분류에 따른 빈도는 국소적 병변이 13예(48.2%)로 가장 흔하였고, 병리학적 불일치가 11예(40.7%), 시술자 오류는 3예(11.1%)였다. 원인에 따른 시술 전 병리소견은 병리학적 불일치 11예에서는 모두 저이형성 선종이었고, 국소적 병변에 의한 13예에서는 11예 (84.6%)가 선암으로 통계학적으로 유의하였다. 그리고 시술자 오류에 의한 경우는 주로 전정부 융기성 병변에서 특히 주변에 장상피화생이 동반된 경우였다. 병리학적 불일치가 원인인 11예 중 10예(90.9%)가 타 병원에서 전원된 경우였고, 장상피화생은 시술자 오류가 원인이 된 경우가 100%였다. 결론: ESD 후 병리학적 음성예를 감소시키기 위해서는 특히 저이형성 선종의 경우 시술 전 병리의사와의 긴밀한 협조와 충분한 의사소통이, 장상피화생이 동반된 전정부의 융기성 병변에서는 병변의 정확한 위치를 확인한 후의 신중한 시술이 필요하다. 하지만 보다 흔하게는 병변이 너무 작아 조직검사로 제거되는 경우도 있다는 점을 염두에 두어야한다. Background/Aims: Endoscopic submucosal dissection (ESD) is accepted as a standard treatment of early gastric cancer (EGC) and gastric adenoma, occasionally, tumorous lesion is not found and pathologic discrepancies can occur after ESD. The aim of this study was to analyze the factors affecting the negative pathologic results after ESD. Methods: We retrospectively reviewed the data from all patients with gastric neoplasm (276 EGC and 516 gastric adenomas) who were treated with ESD during past 3 years and enrolled the patients who had negative pathologic results. Results: Out of 792 patients treated with ESD, 27 patients (3.4%) were eligible for inclusion. Among the 27 patients, factors affecting the negative pathologic results were, most commonly, the focal lesion (n=13, 48.2%) which was small enough to be removed completely during pre-ESD biopsy, followed by pathologic discrepancies (n=11, 40.7%) between pathologists and lastly the operator factor (n=3, 11.1%) dissecting incorrect lesions. Of the focal lesions, the initial pathologic diagnoses were adenocarcinoma in 11 cases (84.6%). In cases with pathologic discrepancies, all the pretreatment diagnoses were adenoma with low grade dysplasia. In cases caused by operator factors, intestinal metaplasia was accompanied by elevated adenoma in all cases. Conclusions: To decrease negative pathologic results after ESD, an endoscopist should perform ESD after sufficient communication with pathologists, especially for adenoma with low grade dysplasia, and choose correct lesion, especially located at the antrum and associated with intestinal metaplasia. The possibility of total removal of small lesions even by forcep biopsy should be considered.

메를로-퐁티의 지각이론을 통한 현대미술의 상호관계적 표현 연구

The purpose of this study is to review Maurice Merleau-Ponty(1908~1961)’s theory of perception and arts, and examine the contemporary art from a phenomenological perspective based on his philosophy. Therethrough, the researcher attempts to provide for an opportunity to meditate more widely on the expression of arts as phenomenon(phenomenologie) of existence(Etre). Merleau-Ponty saw to it that the body and the world co-exist primitively through the reversibilite(réversibilité) of incarnated ‘vision’. And he argues that what reveals it most is painting. His theory of arts make it possible to meditate on the cases of the perceptual experiences expanded in the contemporary art and the ontological painting of de-representation. In case of the contemporary art that sees the audience’s participation as a major element, the meaning of a work would not be formed by thoughts but audience’s experiences. Such contemporary art is mediated upon not through reason but through the perception of the body, while the meaning of the work would remain incomplete as the process of audience’s experience of perception. This study draws the meaning of the works performed by artists and viewers from the phenomenological perspective through Merleau-Pontys theory of perception.

The present study examined the effects of child maltreatment and self-control on reactive aggression amongst middle-school students and investigated whether students’ self-control had any form of moderating effect on the relationship between child maltreatment and reactive aggression. The participants of this study consisted of 482 students (204 boys and 278 girls) from four middle schools located in Seoul and Gyoung-gi province. The Peer Conflict Scale (Marsee, Kimonis, & Frick, 2004) was used to measure the level of reactive aggression. The level of child maltreatment was assessed by means of the Child Trauma Questionnaire (Bernstein & Fink, 1998). Self-control was measured by the Self-Control Scale (Nam, 1999). Statistical analyses of data used for this study comprised the following methods; frequency, mean, standard deviation, and hierarchical regression. The moderating effect of self-control was analyzed by using the procedures proposed by Baron and Kenny (1986). The results indicated that the level of child maltreatment increased the level of reactive aggression whereas the level of self-control decreased the level of reactive aggression. In addition, self-control moderated the influence of child maltreatment on student’s reactive aggression. As a result, the influence of child maltreatment upon reactive aggression was greater when the level of self-control was low, compared to when it was high.

The purpose of the study is two-fold. First, it attempted to understand the experiences of sport club leaders in regards to coeducational sports club after school. The second, it analyzed the educational meaning of sport club in connection with sport for all. To accomplish such purposes, this study conducted a study with an inquiring process on the basis of a narrative approach targeting a sports club leader who didn`t have an on-site instructional experience in school physical education. This study collected data through official & unofficial interviews, documents of the instructional process, on-site notes, and electronic mails. This study utilized Spradley(1980)`s taxonomic analysis method as a major analysis method. The results were roughly divided into 4 sorts of narrative. First, the research participants experienced a ``Shock`` of having to understand and accept his/her own gender stereotype. Second, they experienced sex discrimination and reverse discrimination at the same time in the instructional process that is in pursuit of gender equality education; thus, the participants experienced its subsequent ``Conflict.`` Third, the participants experienced a ``Challenge`` in which the leader compromised with him/herself using the instructional method of ``Mingling`` and ``Distinction.`` Fourth, the participants experienced ``Discovery`` of the instructional method, which was authentically gender-equal within the framework of students. Viewed from the pedagogical perspective, such experiences should work as a basis on which a sports club leader could improve his/her specialization that can connect school physical education and sports for all.
