Seo Jae‐Hwi,Kim Kyo‐Jin,Kim Hoon,Moon Myung‐Jin 한국곤충학회 2020 Entomological Research Vol.50 No.12

Vibration receptors appear to be more necessary for web‐building spiders, but most knowledge of arachnid lyriform organs comes from the study of wandering spiders affected by ground vibrations. Here, we examined the fine structural aspects of the lyriform organs in the web‐building spider Nephila clavata using field emission scanning electron microscopy (FESEM) to fill the gap. The lyriform organ is found in all appendages, including the femur, patella, tibia, and metatarsal segments. A number of slit receptors of various sizes are distributed in the parallel orientation of the cuticle along the long axis. According to its fine structural characteristics, all lyriform organs of this spider are classified as a compound type with multiple cuticular slits. However, the number of cuticular slits per each lyriform organ varies considerably from a minimum of three to a maximum of 17. A total 35 pairs of lyriform organs were counted from an adult female spider. Except for small numerical variation in the 4th appendage, the distribution is remarkably constant within each appendage. Comparing the total number of cuticular slits per each appendage, the 3rd appendage has the highest number (85), but the 4th appendage shows the least number (63). Based on the total number of cuticular slits per leg segment, the patella segment seems to be the most sensitive to vibration reception in this orb‐web spider.

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.

TV 드라마에서의 제품 배치(PPL)의 광고효과 측정 : 암묵적 기억 측정을 통한 접근

김재휘,안정태 한국방송광고공사 2004 광고연구 Vol.0 No.64

본 연구는, 회상이나 재인과 같은 명시적인 기억의 측정이 아닌, 암묵적 기억의 측정을 통하여 TV드라마에서의 간접 광고 PPL의 효과를 검증하고자 하였다. 연구는 예비실험을 거쳐 2개의 본 실험으로 진행되었으며, 예비실험에서는 명시적인 기억 수준에서 PPL의 효과를 측정하였고, <실험 1>에서는 암묵적 기억의 측정방식으로 주로 사용되는 문장 완성 검사를 통해서 PPL 효과를 검증하였다. <실험 2>에서는 점화효과의 이론을 응용하여, TV 드라마 후에 제공되는 프로그램 광고의 기억 측정을 통해서 PPL의 효과를 간접적으로 측정하였다. <실험 1>에는 101명, <실험 2>에서는 171명의 대학생들이 참가하였으며, 각각의 실험에서, 실험집단에는 PPL이 있는 TV 드라마를 시청하게 하였고, 통제집단에게는 PPL이 없는 TV 드라마를 시청하게 하였다. <실험 1>의 결과, 문장완성검사에서 실험집단이 통제집단에 비해 PPL 브랜드와 관련된 문장완성 수행점수가 높게 나타났다. <실험 2>의 결과, 12편의 프로그램 광고 중에서, TV 드라마에서 PPL로 노출되지 않은 브랜드의 광고(비타깃 광고)에 비해, 드라마에서 PPL로 노출된 브랜드의 광고(타깃광고)의 회상이 높았으며, 또한 실험집단과 통제집단 간에 PPL된 타깃광고의 회상 및 기억에서 유의미한 차이가 발견되었다. 이 결과들은 PPL의 광고효과는 분명히 존재한다는 것을 의미하며, 나아가, PPL과 같은 간접 광고의 효과 측정을 위한 새로운 접근법을 제시하고 있다. This study aimed to examine advertising effects of PPL in TV dramas with measuring the priming effects due to implicit memory indirectly as an alternative to the prior way which have relied on direct recall or recognition for brands. The study consisted of a pilot test and two main tests: the pilot test to measure the explicit memory for PPL, the first test to measure the implicit memory for PPL through the priming theory of advertisements after PPL in TV dramas, and the second test to measure the effects of PPL using the sentence completion test which have mostly used to estimate implicit memory. The result shows that there is a significant difference in the rate of memory for advertisements after TV dramas according whether there exists priming effects of PPL or not, and there is a significant difference in the rate of sentence-completions according to whether there exists PPL or not. The result from the fist test suggests that the implicit memory for PPL can be verified by revealing the priming effects of PPL on the memory for advertisements after TV dramas though PPL in TV drama has very limited stimuli to have effects on explicit memory. Also, the result from the second test is consistent with the result from the first test, and it supports that it is a validated way to test the effects of implicit memory for PPL using priming effects.

본 연구는 소비 환경에서 기업과 관련된 정보가 소비자의 구전을 통해 자발적으로 전달되는 현상에 주목하고, 해당 기업에 대한 소비자의 사전태도에 따라 기업의 긍정적 정보 혹은 부정적 정보가 구전에 미치는 영향이 어떻게 달라지는가를 알아보고자 하였다. 이를 위해, 본 연구에서는 기업 정보의 특성과 기업에 대한 소비자의 사전태도를 독립변인으로 하는 2(긍정적·부정적 정보)×3(부정적·중립적·긍정적인 사전태도)의 요인설계를 하였으며, 직접 제작한 가상의 기업 정보를 이용하여 C대학에 재학 중인 186명을 대상으로 실험을 실시하였다. 그 결과, 긍정적 정보보다 부정적 정보에서 구전의도가 더 높게 나타났으며, 긍정적·부정적 정보의 특성과 기업에 대한 소비자의 사전태도에 상호작용 효과가 나타나, 정보 특성이 구전 의도에 미치는 영향은 소비자의 사전태도에 따라서 다르게 나타난다는 것을 확인할 수 있었다. 긍정적 정보에 대한 구전 의도는 기업에 대한 소비자의 사전태도가 긍정적일수록 점진적으로 증가하는 것으로 나타났다. 그러나 부정적인 정보에 대한 구전 의도는 기업에 대한 소비자의 사전태도가 부정적일수록 증가하는 것으로 나타났는데, 특히 소비자의 태도가 중립 이하로 부정적일 때 구전 의도가 급격하게 상승하는 것으로 나타나, 기업에 대한 태도가 부정적일 때 정보 특성에 따른 구전의도가 크게 차이난다는 것을 확인할 수 있었다. This study focused on the social phenomenon of information diffusion about the corporation by Word-of-Mouth(WOM) and investigated the influence of information types on the intention of WOM, especially depending on the consumer’s prior types toward corporation as a object of WOM. An experiment was conducted in a 2(positive and negative information), (consumer’s positive, neutral and negative attitude) factorial design to test hypotheses. 186 undergraduates students participated in the experiment as subjects. The results of empirical testing are as follows: First, the intention of Word-of-Mouth was higher about negative information than about positive information. And interaction effect was found between information types and consume’s prior attitude toward the corporation. The influence of information types on the intention of WOM may be different depending on consumer’s prior attitude. That is, the more positive prior attitude a consumer has, his or her intention of WOM about positive information gradually increased. But the more negative prior attitude a consumer has, the more his or her intention of WOM about negative information increased. Particularly, there was little difference from positive condition to neutral condition, but from neutral to negative condition, intention of WOM about negative prior attitude increased radically. In conclusion, the results shows that in the process of WOM, the influence of information types on intention of WOM may be dependent on consumer’s prior attitude toward a object of WOM. The implication and limitations of this research are discussed.

이재휘,박형식,권준호 大韓顎顔面成形外科學會 1989 Maxillofacial Plastic Reconstructive Surgery Vol.11 No.1

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.

Art and science to determine the treatment objectives, specifically, the desired soft tissue changes are firstly established by using the clinician's “esthetic sense” of the facial beauty and proportion aided to a few cephalometric guidelines. In this sense, the dependence on the clinician's “esthetic eye” by Dr. Bell is more important in analyzing the facial proportion than the satisfaction of rigid cephalometric norms. The purpose of this article was to elucidate the indication for simultaneous surgical repositioning of the maxilla, mandible, and chin, and to describe the clinical cephalometric analysis for orthognathic surgery. Representative 6 case reports were presented and discussed to illustrate the esthetic, orthodontic, and surgical treatment objectives with long-term follow-up.
