The purpose of this investigation was to see whether preschoolers(children of 3, 4, and 5 years of age) understand the fundamental ontological distinction between the internal mental world and objective physical reality. Real physical objects can be distinguished from mental entities on the basis of three criteria. (1) Behavioral-sensory evidence → whether the entity can be seen, touched, and physically acted upon. (2) Public existence→ whether other persons experience the entity. (3) Consistent existence→ whether the entity consistently exists over time. In consistent with previous research findings which tested Western children, the results demonstrated that even 3-year-olds were able to judge real and mental entities appropriately on the basis of the three criteria. The findings are discussed briefly in relation to the Piaget's characterization of young children as realists and recent researches on children's understanding of the mind.

교정의사가 선호하는 측모의 유형에 따른 특징적 양상에 관한 연구

김영진,김정환 대한치과교정학회 2001 대한치과교정학회지 Vol.31 No.5

교정 치료의 목표를 설정하는 데에 있어서 여성의 아름다운 측모에 관한 정확한 이해는 필수적인 요소이다. 본 연구에서는 치과교정의사 간에 심미안의 차이가 있는지를 조사하고, 치과교정의사에 의해 선호되는 여성의 심미적인 측모를 선정하여, 이들이 facial convexity의 정도에 따라 심미적인 측모를 구성하기 위한 특징적인 양상을 보이는지를 조사하고자 하였다. 먼저 교육적 배경이 다른 5명의 치과교정의사로 하여금 133명의 20대 여성의 측모 사진을 이용하여 선호도에 따라 심미적인 측모를 채점하도록 하였다. 심미적인 측모를 가졌다고 판정된 35명의 측모 두부 방사선 사진의 투사도를 작성하여 연조직 분석을 시행하였고, 이를 facial convexity의 정도에 따라 convex군(G-Sn-Pg≥9˚)과 straight 군(G-Sn-Pg<9˚)의 두 subgroup으로 세분화하였다. 심미적인 측모를 선정하는 데에 있어서의 객관성 여부를 조사하기 위하여 5명의 치과교정의사 간의 심미안의 차이에 대한 동질성 검정을 시행하였는데 미의 기준이 주관적임에도 불구하고 치과교정의사간에 측모 선호 양상은 통계적으로 유의한 차이가 없었다(p<0.05). 안모 형태의 차이에 따라 세분된 두 subgroup간의 코의 전후 관계를 나타내는 N-Pg-Sn, N-Pg-Pn에서 통계적으로 유의한 차이를 보였고(p<0.05), nasolabial angle, labiomental angle, 그리고 수직적 분석 항목에서 통계적으로 유의한 차이가 없었으며(p<0.05), 상하순 돌출도를 분석한 결과에서 H-angle, Ls to E line, Li to E line, Pg to Sn perp.에서 통계적으로 유의한 차이를 보였으나 Sn-Pg line와 Sn perp. 에서부터의 거리에는 차이가 없었다(p<0.05). 이상의 결과에서 안모 형태(facial pattern)에 따라 심미적인 측모를 구성하기 위한 특징적인 양상의 차이가 존재하며, 이는 특히 코와 상하순, 그리고 턱의 전후방적인 위치에 따라 크게 좌우됨을 알 수 있었다. The perception of facial esthetics is critically important to orthodontists. A viewpoint to facial esthetics is influenced by various factors and dependent on the perception of observer. The purpose of this study was to examine the differences regarding esthetic viewpoints among orthodontists, to identify attractive profiles preferred to orthodontists and to present the characteristic aspects of attractive profiles upon the degree of facial convexity. 35 Persons whose faces were judged as attractive one by 5 orthodontists were selected out of 133 young Korean women. Soft tissue profiles identified as a good-profile group were measured and analyzed. And then according to the facial convexity, good-profile group was subdivided to convex (G-Sn-Pg9˚) and straight (G-Sn-Pg<9˚) groups for the purpose of this study. There were statistically no significant differences regarding esthetic viewpoints among 5 orthodontists(p<0.05), even if there exists prevailing concept that the standard for facial esthetics is substantially subjective. N-Pg-Sn and N-Pg-Pn, measured for determining anteroposterior relationship of midfacial convexity, showed significant differences statistically between 2 subgroups (p<0.05) while nasolabial angle, labiomental angle, and vertical measurements didnt show statistically significant difference between 2 subgroups (p<0.05). And all the measurements related to lip position, H-angle, Ls to E line, Li to E line and Pg to Sn perp., had statistically significant differences between 2 subgroups (p<0.05). The results indicate that the attractive facial profile has different characteristics to be recognized as a good facial pattern, which depend strongly on anteroposterior position of nose, upper and lower lips, and chin.

Rhabdomyolysis is a biochemical and clinical syndrome caused by lysis of skeletal muscle cell and release of muscle cell contents into the circulation. In addition to traumatic cause, various nontraumatic causes have been reported. Rhabdomyolysis has frequently been associated with seamy aspects of life and society: alcoholic abuse, drug addiction, sadistic drill exercise, war events and attempted suicide. The abuse of alcohol causes many hazards in many organs. One of these is acute alcoholic myopathy that may present as a fulminent syndrome of muscle pain and tenderness associated with rhabdomyolysis and acute renal failure. Because the prognosis of adequately treated rhabdomyolysis is excellent, early recognition and prompt management are essential in emergency situation. We experienced two typical cases of alcohol-induced rhabdomyolysis with acute renal failure and report these cases with literature review.

Invasive pulmonary aspergillosis is known to have a poor prognosis and major cause of morbidity and motality in patients with hematologic disease. Without adequate therapy, invasive pulmonary aspergillosis will almost always progress to fatal pneumonia. Early administration of antifungal agents in patient with invasive pulmonary aspergillosis is most important. And surgical resection of aspergillous-infected tissue may be useful in patients with lesions that are contiguous with great vessel and lesions causing hemoptysis. We reported a rare case of surgical resection as curative treatment for invasive pulmonary aspergillosis patient in 58-year-old man who had the history of acute myeloid leukemia.

Dieulafoy’s lesion is very rare cause of gastrointestinal bleeding, Deiulafoy’s lesion is exposure of non ulcerative, abnormally large tortuous, thick- walled artery in the muscularis mucosa through a small submucosal defect. It is usullay found on stomach antrum and lesser curvature side of the proximal body, and possibly found on any sites throughout whole gastrointestinal tract, but rarely on rectum. The principal of treating Dieulafoy’s lesion was the surgical resection of lesion, but recently remarkable advances in endoscopic technique make endoscopic approach more popular. We report a case of rectal Dieulafoy’s lesion successfully treated with endoscopic hemoclipping in an elderly female patient.

Chitosan is the deacetylated product of chitin. Chitosan and its derivatives have many properties that make them attractive for a wide variety of health applications. We reported recently that water soluble chitooligosaccharides have hepatoprotective effect on ethanol induced liver injury in the mouse. The current study examined the effect of water soluble chitooligosaccharides on CC1₄-induced liver injury in rats. Male Sprague-Dawley rats were orally treated with CC1₄without or with administration of 5% chitooligosaccharides. After 5 weeks after CC1₄treatment, the histological sections and the expression of mRNA of interleukin-12(IL-12), hepatocyte growth factor(HGF), and tumor necrosis factor(TNF- ) were examined. The liver section of rats supplemented with chitooligosaccharides showed attenuated effects of the necrosis, steatosis, cirrhosis compared with those of non-supplemented rats. The level of TNF- mRNA in CC1₄-treated rats were higher than those in the rats supplemented with chitooligosaccharides, while the levels of IL-12 and HGF mRNA were higher in the rats supplemented with chitooligosaccharides than those of in CC1₄-treated rats. These findings suggested that water soluble chitooligosaccharides may have a hepatoprotective activity against CCl₄-induced liver injury in rats.
