Radiofrequency ablation(RFA), as a form of minimally invasive therapy for hepatocellular carcinoma, has become an important treatment modality. Because of limitation of surgery, RFA has become standard therapy for hepatocellular carcinoma in some situations. But there are some complications of RFA such as bleeding, infection, hematoma, adjacent organ thermal damage including intestinal perforation, needle track seeding, and so on. There are few reports in the literature that systematically evaluate the incidence of needle tract seeding and its associated risk factors. And only 2 cases of needle tract seeding of hepatocellular carcinoma after RFA were reported in Korea. We report a case of needle tract seeding of hepatocellular carcinoma after RFA.

Tuberculous peritonitis is discovered from sixty to ninty percent of pulmonary tuberculosis patients. Clinical symptoms are nonspecific such as mild fever, weakness and malaise but show tenderness in right lower abdomen and abdominal distension. Diagnosis is confirmed by laparoscopic and pathologic findings. We report a case of tuberculous peritonitis in an 11-year-old boy who was hospitalized because of abdominal distension with pain on right lower abdomen which had developed one day before he came to hospital. Chest X-ray showed pleural effusion on both sides. We did laparoscopic examination and observed diffuse nodular infiltration. In biopsy specimen we observed osseous granuloma and acid-fast bacilli in AFB stain.

본 연구는 스포츠팬의 심리적 특성이 스포츠 관전행동에 영향을 미친다고 가정하고, 스포츠 관전동기와 스포츠팬 정체성의 다양한 차원들 중 스포츠 관전행동을 결정하는 요인들을 밝히고자 하였다. 질문지 조사를 통한 연구 결과 정체성현출성, 친지관계동기, 대리만족동기, 성별의 네 가지 변인이 스포츠 관전행동을 결정하는 요인으로 밝혀졌다. 또한 관전자 특성에 따라 관저행동에 영향을 미치는 관전동기 및 스포츠팬 정체성 요인에 차이가 있는 것으로 나타났다. 즉, 스포츠팬의 성별 및 소극적 관전수준에 따라 관전행동에 영향을 미치는 관전동기 및 스포츠팬 정체성의 구성요소가 달라졌다. 이러한 연구 결과를 스포츠 마케팅에 활용한다면, 관전자 특성에 따라 보다 세분화된 마케팅 전략을 수립할 수 있을 것이다. Watching sport events represents a predominant form of leisure today. Many people attend sport events and think of themselves as sport fans, So, It is needed to understand psychological natures of sports fans and which of psychological natures lead spectators to stadium. Then we could know what makes more steady and devoted fans. Based on previous researches, we could expect that spectator motivation and fan identity would influence on sporting game attendance of spectator. Also we could expect there were sexual differences in effects of motivation and identity factors. To examine these propositions, we performed survey research. Questionnaire of this study included the scales for sports spectator motivation, fan identity dimensions, sport spectating experiences, and demographic variables. Data of this study were collected from 192 college students. The results of the survey analysis verify relationship motive, identity salience, sex, and vicarious satisfaction determine attendance of sporting games. And there were sexual differences in effect of motivation and identity dimensions. These results meant men and women want different benefits through watching sporting events. Therefore, it is needed diverse marketing strategy according to spectators' natures.

This is a report of 2 cases on old maxilla fractures accompanied with sagittal palatal fracture and severe malocclusion. We treated them by using of classic Le Fort 1 osteotomy and modified Le Fort I osteotomy along the old fracture lines satisfactorily. The results obtained from treatment are as follows : 1. Careful examination and correct care on sagittal palatal fracture should be need during initial diagnosis and emergency care of maxilla fracture showed malocclusion. 2. Although early definite treatment of maxilla injuries is difficult due to major organ injuries associated with accident, the positive effort to induce normal occlusion is always necessary as soon as possible. 3. In the cases of malocclusion due to transverse discrepancy of maxillary dentition associated with injury as like as our cases, classic and modified Le Fort I osteotomy and rigid internal fixation were useful to correct occlusion, to ease operation and return normal functions early.

This paper presents a cursive on-line handwritten Hangul recognition model which permits cursive writing between graphemes. Add semantics to the basic stroke types possessed by graphemes and expand stroke types. Also, by the design of attribute grammer more accurate feature values will be elicited. The combination of the feature values with genetic algorithm and BP will improve the neural networks model, and this type of learning will increase the recognition rate and reduce the learning time. In this paper, this new on-line handwritten Hangul recognition model is proposed.

본 연구에서는 인터넷 광고에 대한 소비자들의 시각적 주의를 검증하기 위해 아이 트래커로 실험을 진행하였다. 인터넷 포털 사이트에서 실제로 집행된 광고를 실험 자극으로 선정하였으며, 광고 속성들과 소비자들의 인터넷 사용 목적이 시각적 주의에 영향을 주는지 검증하고자 하였다. 본 연구에서는 자극유형(텍스트/그림), 부분적 겹침(있음/없음), 상대적 높이(상/중/하), 대조(강/중/약), 광고자극 내 대조(강/중/약), 광고 위치(좌/우)의 자극 속성들과 과제 조건(유/무)의 주효과 및 상호작용을 검증하고자 하였다. 연구결과 자극 속성인 광고 제시 유형, 대조, 광고 자극 내 대조와 과제 탐색은 각각의 주효과와 상호작용 효과가 모두 유의미하였으나, 부분적 겹침, 상대적 높이는 상호작용만 유의미하였다. 한편, 뇌의 반구 처리 유형에 의한 그림/텍스트 광고의 좌우 위치 효과의 결과는 가설과 일치되지 않는 결과를 나타내었다. The purpose of this study was to examine the attention to the internet ads of consumers. Unlike the prior studies, this study was collected the eye fixation data of participants through the eye tracker apparatus. The results showed that the participants attended to the ads as a result of activating top-down processing, caused by their goal of using internet and learned visual searching route. In addition, each type of ad(pictorial and text) was gathered different visual attention as a result of bottom-up process and was interacted with goal of using internet. And stimuli attributes in the ads, like partially occlusion and contrast led to participants’ attention to the ads differently. But relative height in the visual field had no significance and locations of ads didn’t have correspondent results. Finally, limitations of this paper and future research directions were discussed.

This study was carried out to test the body fat breakdown during topical seaweed extract treatment and in combination with the aerobic exercise. Of 20 female obesity subjects, ten treated a cream types of seaweed extract(control group) and ten treated a placebo cream(placebo group). Topical treatment of each sample was designed for 4 weeks, and treated with 2 times a day about 10ml on the abdomen and the thigh, respectively. All subjects were participated aerobic dance half hour a day and four times a week. After 4 weeks of topical treatment and exercise, they were measured body fat, skinfold thickness, body circumference. Then venous blood samples were taken and analyzed blood cells, serum enzymes, and serum lipids. There were reduction of body weight, % of body fat, antebrachium, brachium, chest, waist, thigh circumference and abdomen thickness between pre and post treatment in both group. Especially, body weight and % of body fat significantly reduced in the subjects treating the seaweed extract than those treating the placebo. There were significant decrement in total cholesterol and LDL whereas increment in HDL and TBIL in the control group, but no significant difference in the placebo group. In conclusion, there were 7.6% of body fat reduction during 4 weeks of aerobic exercise and 21% of body fat reducement in combination of topical seaweed treatment and exercise, respectively. These results suggest that the topical treatment of seaweed extract should be very effective for fat breakdown. Especially, the body fat breakdown maximized in the combination with the topical seaweed extracts treatment and the aerobic exercise.

Purpose : This study was conducted to develop field triage, transportation, distribution, and prehospital care at a fire disaster by analyzing the victims of the fore that broke out at a bar in Incheon. Method : We analyzed the cases of the victims of a fire in Incheon in Oct. 1999. We determined the primary care hospital, the arrival time, the burn size, the outcome, and the injury type from the medical records, the concerned organ records, and interviews with concerned persons. Result : The total number of victims was 137: 56 prehospital deaths, 1 hospital death, and 80 survivals. The Pearson correlation coefficient between the burn size and the severity was -0.175. There were 121(89.6%) cases of inhalation injury, 59 (43.7%) cases of flame burns, 66 (48.9%) cases of hypoxic brain damage, and 16 (11.9%) cases involving other types of injury. Conclusion : The causes of death of the fire victims were inhalation injury and hypoxic brain damage due to CO poisoning and other toxic inhalants. We propose the use of a simple triage and rapid treatment(START) system and a reassessment the delayed category in fire disasters.

<P><B>Abstract</B></P> <P>Hydroquinone (HQ), a major metabolite of benzene, exists in many plant-derived food and products. Although many studies have addressed biological properties of HQ including the regulation of immune responses and antioxidant activity, neuroprotective effects of HQ following ischemic insults have not yet been considered. Therefore, in this study, we examined neuroprotective effects of HQ against ischemic damage in the gerbil hippocampal cornu ammonis 1 (CA1) region following 5 min of transient cerebral ischemia. We found that pre- and post-treatments with 50 and 100 mg/kg of HQ protected CA1 pyramidal neurons from ischemic insult. Especially, pre- and post-treatments with 100 mg/kg of HQ showed strong neuroprotective effects against ischemic damage. In addition, pre- and post-treatments with 100 mg/kg of HQ significantly attenuated activations of astrocytes and microglia in the ischemic CA1 region compared to the vehicle-treated-ischemia-operated group. Briefly, these results show that pre- and post-treatments with HQ can protect neurons from transient cerebral ischemia and strongly attenuate ischemia-induced glial activation in the hippocampal CA1 region, and indicate that HQ can be used for both prevention and therapy of ischemic injury.</P> <P><B>Highlights</B></P> <P> <UL> <LI> Low dose of hydroquinone (HQ), a tumorigenesis-inducing factor, does not show neuronal damage. </LI> <LI> Pre- and post-treatments with HQ significantly protects neurons from transient cerebral ischemia. </LI> <LI> Pre- and post-treatments with HQ significantly attenuate ischemia-induced gliosis. </LI> <LI> HQ could be a novel compound for postischemic therapy after cerebral ischemic insults. </LI> </UL> </P>
