In an attempt to better define the cytologic characteristics of schwannomas, we have reviewed aspirates and corresponding histologic sections from 23 schwannomas. Of this number, the original cytologic diagnoses were: schwannoma in 14 cases (61%), benign soft tissue tumor in 2 cases (9%), and insufficient specimen in 7 cases (30%). The cytologic findings common to all cases of schwannoma included fragments of tightly cohesive fascicles with variable cellularity and corresponding Antoni type A area. The Antoni type B area, consisting of scattered spindle cells and some histiocytes and lymphocytes against a myxoid background, was seen in 14 cases. Fibrillary stroma was seen in 12 cases. The tumor cells had spindle- or ovalshaped nuclei, with pointed ends and indistinct cell borders. Nuclear palisading was seen in 10 cases, and distinctive Verocay bodies were seen in 5 cases. In ancient schwannomas, there were no Verocay bodies. Most schwannomas have distinct cytomorphologic features that allow correct diagnosis. The major problem with fine needle aspiration cytology of these tumors is the high frequency of poor cellularity, particularly in lesions with cystic degeneration. Of 7 cases with insufficient specimen, 4 showed marked cystic changes and 1 showed marked hyaline changes on histologic sections. In conclusion, we believe that if cytopathologist reminds the situation such as cystic degeneration or hyaline degeneration, the correct diagnosis of the schwannoma will be easily made.

Soft tissue calcifications after burn injuries are commonly found in the periarticular region. They can easily be found because they cause severe pain and distress to the patient. However, a long period is required to identify extra-articular soft tissue calcification after burn injuries because they have no specific symptoms. Herein, we present the case of a patient with dystrophic extra-articular soft tissue calcification after a burn injury. A 70-year-old woman developed a non-healing ulcer in the right lower leg area two months before presentation to the hospital. She had third-degree flame burns on the anteromedial tibial area of the right leg approximately 40 years prior, and there had been no particular problem. Examination revealed chronic ulcers, and a review of radiograph findings revealed irregular calcification. The wound was treated with wide excision with a skin graft, and it healed without complications. During follow-up one month later, no recurrence of the calcification or ulceration of the lesion was found.

콕시디오이데스 진균증은 미국 남서부 지역의 풍토병으로 알려져 있고 국내 발병 사례가 적으므로 진단에 혼선과 지연을 초래할 수 있다. 따라서 풍토지역 거주력이나 여행력을 문진하는 것이 매우 중요하고 호산구 증다증을 동반할 경우 콕시디오이데스 진균증을 감별질환의 한 가지로 생각해야 할 것이다. 또한 의심이 되는 경우 적극적인 조직검사 및 엄격한 보호아래 시행되는 배양검사를 통한 진단과 치료가 필요하겠다. 저자들은 C.immitis 풍토지역인 미국 애리조나 주에서 거주 후 입국한 정상 면역력환자에서 다발성 폐경화 및 폐문부 림프절 비대 소견을 보여 조직 검사와 기관지세척액 및 폐조직배양검사를 통하여 폐 콕시디오이데스 진균증으로 진단한 1예를 경험하였기에 문헌고찰과 함께 보고하는 바이다.

교정치료 후 연조직의 변화가 나타난다. 특히, 하안면부위에 많은 변화를 일으키게 되며, 대표적으로 입술은 치아 이동량의 $60\~70\%$정도 이동한다고 알려져 있다. 하지만, 이동량은 개인마다 그 양상이 다양하다. 본 연구는 환자의 입술두께에 따라 연조직 이동 양상에 차이가 있는지 여부를 조사하는데 그 목적이 있다. 발치를 동반한 교정치료를 받은 성인환자를 대상으로 basic upper lip thickness에 따라 환자를 분류한 결과, 두께가 얇은 군(group 1)에서 치료 후 연조직 변화에 영향을 미치는 요인으로는 mentolabial angle와 하순의 변화간에 음의 상관관계를 보였다. 두께가 평균인 군(group 2)에서 상순의 변화에 영향을 미치는 요소로는 상악전치의 변화, 하악전치의 변화, 하순의 변화, nasolabial angle의 변화로 나타났으며, 하순의 변화에 영향을 미치는 요소로는 상순의 변화, 상악전치의 변화, 하악전치의 변화로 나타났다. 두께가 두꺼운 군(group 3)에서 는 상순, 하순의 변화는 전치위치의 변화나 연조직 변화와는 관련 없음으로 관찰되었다.

This study provides the basic resource for establishing the environment design policies around elementary school for the students and analyzes the actual pedestrian environment conditions of elementary school in order to improve safety of from crime for them. For this, the field survey are conducted on risk of from crime in 10 sidewalks of 5 elementary schoolin Ilsan new town. The result of this are the followings ;1) There are schools which have difference between the height of road and the height of pedestrian path. 2) There are schools which are insufficient distance for securing front sight because of shape of pedestrian path. 3) In entrance there are facilities interfering with natural surveillance within school boundaries such as stone written school motto, storehouse, wash room, doorpost. 4) In entrance there are schools with no security office, emergency bell and CCTV. 4) The openness in the bottom of fence is lower than that of upper because of shrubs and material of fence. 5) There are concealed places and cars in back gate area interfering with natural surveillance.

Actinomycosis is an unusual granulomatous infection caused by gram-positive anaerobic bacteria called Actinomyces species(predominantly Actinomyces israelii), which is a common and normally nonpathogenic organism found in the nose and throat. The three major clinical presentations of actinomycosis include the cervico-facial(the most common, 55%), thoracic, and abdominopelvic region. Actinomycosis typically has a chronic, indolent course characterized by swelling and induration of the soft tissues and eventual spontaneous drainage through multiple sinus tracts. Actinomycosis is difficult to diagnose because of variable presentation mimicking neoplasm and fastidious nature of the organism in culture. We present a case of actinomycosis in the parotid tip area which was mistaken for a salivary tumor.

Laryngeal hemangioma occurs mostly in infantile patients and infantile hemangiomas can be frequently seen in the subglottic area. So, respiratory distress is a main symptom in this entity. But adult hemangiomas are rare and can be seen in different locations such as in epiglottis, aryepiglottic fold, arytenoids and false and true vocal folds. Authors experienced a case of mixed hemangioma at the right aryepiglottic fold in a 42 years-old-man who was presented with snoring, throat foreign body sense for 3 months. So, we report this case with a review of the literature.

A transparotid approach, with a retromandibular or preauricular incision, is an alternative surgical approach for treating a subcondylar fracture and reducing the potential for complications such as injury to the facial nerves. However, retromandibular and preauricular incisions are both created far away from the parotid gland-dissection area. Thus, it is necessary to undermine the skin and retract it anteriorly to access the surgical field. Here, we introduce a modified approach wherein the incision allows for direct access to the fracture site. This approach may be adopted to shorten the incision length, reduce the retraction trauma at the surgical site, and help prevent injury to the facial nerve.

The purpose of this study was to examine the relationship between consumer spatial behavior and consumer characteristics based on trade area selection criteria 469 female consumers who lived in the two new towns near Seoul, Bundang and Ilsan, participated in the study by completing questionnaires. Data were analyzed by using cluster analysis, ANOVA, Duncan's multiple range test, chi-square analysis, etc. The findings of the empirical research were as follows: 1. Five groups were identified by cluster analysis based on trade area selection criteria of clothing price-oriented group, time convenience-oriented group, shopping convenience-oriented group, variety/entertainment-oriented group, and passive shopping group. 2. Each group differed in spatial behavior such as clothing shopping area, the visiting frequency, and spatial movement type. 3. Each group showed differences in fashion involvement and demographic characteristics(age, marital status, education, occupation and social status).
