The aim at the evaluation of scholarship is to promote efficiency in learning, and to attain the achievement of all true and worth-while education. In other words, the evaluation will not only induce the impulse of students' self-betterments but serve professors a good reference for future's reform measure. Some promblems in it of test scores are examined here. After a scholastic tes, the number of marks souls correctly be checked by the indifferent scoring standard and be balanced the critical estimation of students' academic work with a calm and impartial head. Reflection increases wisdom and ability; so we at least have the distribution datum made every time and varified the fruit in it. Then the dat a piled up should be compared and weighed though it bears evidence of very serious labor. Because they afford professors an important material for reflection on the future of practising test. But the questions, first of all, must absolutely be good for students.

Osteoma is a slowly growing benign tumor composed of compact or cancellous bone and usually found in paranasal sinuses.Lobular capillary hemangioma is a rapidly growing lesion usually affecting skin and oral mucosa. Both lesions may occur at any age group but most frequently in the third decade. The authors experienced a case of concurrent osteoma and lobular capillary hemangioma in the middle turbinate, which were removed via endonasal endoscopic approach. Concerning our case, we speculate that the slow growth of the osteoma may have caused inflammatory change on nasal mucosa, resulting in lobular capillary hemangioma. We report a case with a review of literatures. (Korean J Otolaryngol 2006;49:339-42)

Herniation of the brain into the midle ear or mastoid is a rare but potentially life-threatening complication of chronic otitis media of brain herniation but this complication still ocurs, with potential devastating sequelae. Because of the non specificity of the clinical signs and symptoms, brain herniation is often discovered incidentaly at the time of surgery for chronic otitis media. The patient was a 56-year-old female who had a history of tympanomastoid surgery for right ear about 7 years ago and had complained g-gested a temporal encephalocele with infected middle ear and mastoid cavity. The patient underwent a repair of the temporal encephalocele and a revision tympanomastoidectomy using the combined transmastoid and midle cranial fossa approach.

Mucous membrane plasmacytosis is a rare benign condition characterized by plasma cell infiltration of the mucosa of upper aerodigestive tract. The lesions typically produce a cobblestone or warty appearance of the larynx, pharynx, palate, lips, mouth, tongue and trachea. Histologically, the lesions are characterized by a diffuse expanse of inflammatory cells situated in submucosal tissues, composed mainly of mature plasma cells with scattered polymorphonuclear cells and lymphocytes. Immunohistochemistry for κ, λ light chain showed polyclonal immunoglobulin content in all cases examined. A variety of medical and surgical treatments have been tried but none has led to improvement in the condition. In this study, we report, with a review of literature, a mucous membrane plasmacytosis arising from oropharynx in a 30 year-old female patient.

표면특성에 따른 물맺힘 특성이 가스흡착성에 미치는 영향

The gas adsorption efficiency for various surfaces with three different characteristics has been reviewed. The dimethyl disulfide gas has been used to investigate characteristics of gas adsorption for different surface characteristics such as plasma treated, lacquer coated and untreated. Three different surfaces were evaluated in dry conditions initially and tested at wet surface conditions with spraying water to evaluate the gas adsorption efficiency which usually occurred at defrost cycles. The results show that the gas adsorption of the plasma treated sample has better performance than others. The lacquer coated and untreated samples showed the similar result, but the lacquer coated sample showed a slightly better performance.

목 적:최근 전적인 모유수유, 일조량의 감소, 미숙아의 증가로 인해 비타민 D 결핍성 구루병이 증가 추세로 보고되고 있으나 국내 연구는 부족한 상태이다. 본 연구에서는 비타민 D 결핍성 구루병으로 진단된 아동들의 임상적 특징에 대하여 조사하였다. 방 법:상계백병원 소아과에 내원하여 비타민 D 결핍성 구루병으로 진단된 아동(n=35) 및 모유수유환아의 모친(n=11)을 대상으로 임상 특징을 분석하였다. 혈액 내 25-OHD3농도가 15 ng/mL 미만인 경우 비타민 D 결핍증으로, 15 ng/mL 이상 30 ng/mL 미만인 경우 비타민 D 불충분증으로 정의하였다. 결 과:대상 환아는 총 35명(남아22명, 여아 13명)이었다. 평균 진단 연령은 7.4±7.1개월(범위: 0.1-29.8개월)이였다. 전체 환아의 51%가 비타민 D 결핍상태였으며 나머지는 불충분상태였다. 전체의 80%가 무증상 구루병으로 진단되었으며 83%가 12개월이 하의 영아였다. 전체 환아 중 57%가 모유수유 중이었으며 29%가 철결핍성 빈혈이 동반되었다. 모유수유아 중 45%가 비타민 D 결핍 상태였으며 모친의 90%가 결핍 혹은 불충분상태였다. 전체 아동의 93%가 방사선 검사상 구루병의 소견이 있었으며 비타민 D 불충분 상태에서도 방사선학 검사상 모두 구루병 소견을 보였다. 결 론:비타민 D 결핍성 구루병이 의심되는 경우 수부 방사선 및 25-OHD3검사를 동시에 시행하는 것이 도움이 될 것으로 사료되며 고위험군의 구루병 예방을 위한 국가적 관심, 역학 조사와 이에 대한 지침이 마련되어야 한다. Purpose:Vitamin D deficiency rickets is a significant public health problem that results from insufficient exposure to sunlight and inadequate vitamin D supplementation. The purpose of this study is to identify the clinical characteristics of vitamin D deficiency rickets in infants. Methods:Data of 35 infants diagnosed as vitamin D deficiency rickets at Sanggye-Paik Hospital, Seoul, Korea, from March 2007 to May 2009 were reviewed. Children with plasma 25-hydroxyvitamin D levels<15 ng/mL and 15-30 ng/mL were considered to have vitamin D deficiency and vitamin D insufficiency, respectively. Results:Thirty-five infants (22 boys, 13 girls) were diagnosed with rickets. Mean age at diagnosis was 7.4±7.1 months (range: 0.1-29.8 months). Eighteen infants (51%) were vitamin D deficient and seventeen infants (49%) were insufficient. Twenty-eight of all (80%) diagnosed as subclinical rickets. Twenty-nine infants (83%) were below the age of 12months. Twenty infants (57%) had breastfed and ten infants (29%) had iron deficiency anemia. Nine of breastfed infants (45%) were vitamin D deficient and ten of their mothers were vitamin D insufficient. Overall, radiographic evidence of rickets was present in 93% of the cases. Radiographic sign of rickets was evident even in vitamin D insufficient state. Conclusion:It is important for the clinician to screen for subclinical vitamin D deficiency rickets in inadequately supplemented infants by pairing 25-hydroxyvitamin D levels with wrist radiographs. A nationwide epidemiological study of vitamin D deficiency rickets must be conducted and evidence-based national guidelines must be defined to prevent rickets.

가상교육 시스템을 운용하는 데 여러 가지 주요 기능이 필요하다. 그 중에 하나가 교육에 관련한 Q/A 게시판 관리이다. 이 게시판은 학습자들이 교육내용에 관련한 다양한 질문을 올리고, 교수자는 질문에 대하여 답변을 올리는 의사소통의 통로이다. 본 연구에서는 가상교육에서 필수적으로 요구되는 Q/A 게시판의 개선된 관리 방안을 설계 구현하였다. 다시 말하면 가상교육 시스템에서 기본적으로 필요한 Q/A 게시판에 올라오는 학습자들의 질문에 대하여 답변을 자동화하는 시스템을 설계 구현했다. There should be a few important functions for operating cyber education systems. Among them, one of the most important functions is to manage question and answer bulletin boards. A question and answer bulletin board is a communication path between learners and teachers. Learners ask questions and teachers response answers to askers on the board. This research designs and implements an improved method for managing question and answer bulletin boards which are mendatory in cyber education. In other words, we design and implement a system which automatically provides answers to the questions.

진단이 지연된 측두골의 전이성 전립선 선암종

Metastasis to the temporal bone is uncommon. In some cases, metastasis may be the first evidence of malignant dissemination, but more frequently, the diagnosis is unsuspected, possibly because ear symptoms are overshadowed by those deriving from the primary tumor. It is not until they have symptoms like hearing loss, otalgia, facial nerve paralysis, periauricular swelling,otorrhea, or even an aural mass that patients usually undergo treatment at the late stage of the disease course. Tumors of the breast, lung, and kidney are the most common sources of temporal bone metastasis. Although axial bone and cranial metastases are common in patients with prostatic carcinoma, temporal bone involvement is extremely rare. We report a case of metastatic prostatic adenocarcinoma in the temporal bone which was diagnosed with delay. Korean J Otorhinolaryngol-Head Neck Surg 2010;53:179-83
