Primary ciliary dyskinesia is a genetic disorder of abnormal ciliary structure and function that leads to defective mucociliary clearance, resulting in sinopulmonary infection and infertility. Kartagener's syndrome is a subclass of primary ciliary dyskinesia and which is clinically distinguishable by the presence of situs inversus. Electron microscopy of cilia reveals ultrastructural defects in the ciliary axoneme. In the respiratory tract, this inability presumably causes impaired clearance of mucus and inhaled particles and results in the chronic infections of sinuses and bronchial trees that are characterized of the disease. Early diagnosis of the disease may be important for prevention of bronchiectasis and pulmonary insufficiency. We report one case of primary ciliary dyskinesia associated with Kartagener's syndrome in a 14 year-old young man who was presented as bronchiectasis, chronic and situs inversus, with review of literature.

Papaverine이 단일 심근세포의 막전류에 미치는 영향

유경현,심태섭,방효원 중앙대학교 의과대학 의과학연구소 1991 中央醫大誌 Vol.16 No.4

Ventricular myocytes of guinea-pig were isolated by means of collagenase digestion in order to investigate the effects of papaverine on the membrane currents in them. After formation of a gigaseal with patch microelectrodes, membrane currents were recorded from single ventricular myocytes in a whole cell mode of patch-clamp technique. For membrane currents recording, electrodes were filled with Cs-solution. Results were as follows: 1. Slow inward calcium was reduced by papaverine dose-dependently. 2. No significant changes were observed in the steady-state inactivation. 3. Recovery time of the calcium currents prolonged in high concencial papaverine. 4. Fast inward sodium currents showed no noticeable changes with papaverine treatment. From these results, it is strongly suggested that the effects of papaverine on the membrane currents in the single ventricular myocytes may be attributable to its antagonistic action on the calcium channel rather than its inhibitory effect on the phosphodiesterase activity.

Teaching Korean as a Foreign Language, 27, 243∼269. One of the problems in teaching Korean as a second language is about vocabulary. It is especially difficult to explain the differences between vocabulary. Therefore, it is useful to apply learner's dictionary in the classroom as a supplementary instrument for effective learning for vocabulary. Current Korean dictionaries do not provide sufficient information regarding distinctive features of the extended notion of synonym. This study describes current issues about the extended notion of synonym and conducts an analysis of several groups of verbs and adjectives as an example. This study also discusses how to apply the extended notion of synonym in lexical education. (Hongik University·Kyunghee University)

The building is getting bigger and higher in urban areas to promote efficiency of land. As a building was built in urban areas. it was built in very close proximity. At stage of underground work, it's extremely necessary to improve retaining wall for raising the quality of construction. The Braced Wall System largely used in Korea because of suitability of construction in close proximity but it can't serve enough space to work. So in this study, a new retaining wall method using Prestress Wales compares with Braced Wall System under several aspects such as time for completion, construction cost, and stability.

This study was designed to investigate the difference of teeth and craniofacial complex between normal occlusion and Angle's Class II, div. 1 malocclusion in korean childern. The sample was divided into 2 groups, the 66 subjects with normal occlusion and 96 subjects with Angle's Class II, div.1 malocclusion in both sexes. The results obtained were as follows: 1. No significant differences were observed in ant. cranial base length & flexure(saddle angle) between normal occlusion & cranial Angle's Class II, div. 1 malocclusion group, but posterior cranial base length of Class II, div. 1 malocclusion group was larger than that of normal occlusion group. 2. No significant difference was observed in the anteroposterior position of Maxilla to cranial base between two groups, but mandibular position in Class II. div. 1 malocclusion was posterior and interior to that of normal occlusion. 3. The length of maxilla (ANS-PSN) was larger in Class II, div. 1 malocclusion than normal occlusion. The length of mandibular body(Go-Me) was nor differnet between Class II, div. 1 malocclusion and normal occlusion. 4. Maxillary incisor position of Class II, div. 1 malocclusion to cranial base was more protrusive than that of normal occlusion, but there was no difference in mandibular incisor position between two groups.

한국어에 심리타동사가 있는가?

유현경 배달말학회 2004 배달말 Vol.34 No.-

이 글은 기존의 연구에서 심리타동사로 보았던 부류들을 심리용언의 일종으로 볼 수 있는지에 대하여 살펴보았다. 이 연구에서는 심리용언은 주어의 내적 심리 상태를 서술하는 용언이라는 의미적인 정의 이외에 주어의 경험주 의미역 할당을 그 필수적 조건으로 보았다. 주어의 의미역에 대하여 살펴본 결과 심리형용사의 주어에는 경험주 의미역이 할당되지만 인지동사나 '-어하다' 동사는 행동성과 의도성의 측면을 볼 때 주어에 경험주 의미역이 할당되기 어려움을 알 수 있었다. 나머지 특성들에서도 심리형용사와 다른 동사들 간의 차이가 현저한 것을 알 수 있다. 용언의 유형은 의미적, 통사적 특성을 공유해야 하기 때문에 심리형용사와 '-어하다' 동사, '생각하다, 믿다, 알다' 등의 인지동사 부류를 심리용언이라는 하나의 유형으로 묶기가 어렵다. 그러므로 한국어에는 심리타동사라는 범주를 설정할 수 없다. In this article, I examine whether the category of psychological transitive verbs can be established in korean. The basis assumption is that the subject of the psychological predicate constructions is Experiencer. Psychological adjectives are different from '-eha' verbs and cognitive verbs(saenggakhada, alda, etc) in the thematic role of the subject. Psychological adjectives have the Experiencer subject, on the other hand, '-eha' verb constructions and cognitive verb constructions have the feature of agentivity and so the subjects of them are not Experiencer. As considering to the other aspects, psychological adjectives differ from '-eha' verbs and cognitive verbs. So-called "the psychological transitive verbs" can not be considered as the psychological predicates. Therefore, there's no the category of the psychological transitive verbs in Korean.

At present, the treatments of the radiation-induced diseases are only performing by the palliative treatment technique. Moreover, radiation protective agents are a little toxic for human being and this seriously limits their applicability with various complications in clinical uses. Accordingly, as a part of the aim of gain of the basic data for protective roles of some radioprotectors, the present investingation was carried out to evaluate the comparative radioprotective effects by the administration of DDC, MEA, WR-2721. Results are shown for statistically significant analysis and correlation with each group as follows; 1. The proper doses of the radioprotectors were DDC; 1,550mg/kg, MEA; 450mg/kg, WR-2721; 780mg/kg of the mouse body weight. 2. DMF(Dose modification factor) of LD50/10 and LD50/30 for whole body irradiation was DDC; 1.2, MEA; 1.4, WR-2721; 1.9 and DDC; 1.7, MEA; 1.8 and WR-2721; 2.5 respectively. 3. DMF for radiation reaction of jejunal crypt was DDC; 1.07, MEA; 1.21 and WR-2721; 1.76 and that of jejunal crypt cell was DDC; 1.04, MEA; 1.08 and WR-2721; 1.38 respectively. 4. Conclusively, WR-2721 was the most effective drung among the three radioprotectors and this result must be a supportive data for further study for clinical application.

This study was performed to measure the skin absorbed doses from full mouth standard intraoral radiography(14 exposures) in bisecting angle and paralleling techniques. Thermoluminescent dosimeters were used in a phantom. Circular tube collimator(60mm in diameter, 20cm in length) and rectangular collimator(35mmX44mm, 40cm in length) were set for bisecting angle and paralleling techniques respectively. All measurement sites were classified into 8 groups according to distance from each point of central rays. The results were as follows: 1. The skin absorbed doses from the paralleling technique were significantly decreased than those from the bisecting technique in both points at central ray and points away from central ray. The percentage rates of decrease were greater at points away from central ray than those at central ray. 2. The skin absorbed doses at the lens of eye, parotid gland, submandibular gland and thyroid region were significantly decreased in paralleling techniuqe, but those of the midline of palate remained similar in both techniques. 3. The highest doses were measured at the site 20mm above the point of central ray for the mandibular premolars in bisecting angle technique and at the point of central ray for the mandibular premolars in paralleling techniques. The lowest doses were measured at the thyroid region in both techniques.

Centrifuge model tests were performed to find appropriate equations proposed previously of estimating the bearing capacity of the composite clayey soil reinforced with sand compaction pile. Model tests were carried out with changing the replacement ratio of SCP (20%, 40%, 70%), contents of fine materials (5%, 10%, 15%) and ratio of treated width to loading width (1B, 2B, 3B). Test results about bearing capacity of the composite ground were obtained by performing the surcharge load tests with measurements of applied loads and vertical displacement. Bearing capacities against bulging and shear failures were estimated by the existing equations. As results of comparing the estimated bearing capacity with experimental values the bearing capacities estimated by Greenwood's equation (1970) for bulging failure mode were similar to the test results.

유현정,김경자 이화여자대학교 사범대학 교육과학연구소 2001 교육과학연구 Vol.32 No.2

본 연구는 초등 음악과 영역에서 아동의 창의성 신장을 위한 동화 활용 음악 학습 프로그램을 개발하고, 이를 학교 현장에서 적용할 수 있도록 하는 데 그 목적이 있다. 21세기의 세계화, 정보화, 다변화의 시대에 부응하는 초등학교 음악교육은 인간의 정서에 작용할 뿐 아니라, 아동의 창의성을 신장시킬 수 있는 음악적 경험을 제공해야 한다. 이에 친숙한 동화의 이야기 자료를 재구성하고, 그것을 음악으로 표현할 수 있는 프로그램을 개발하여 현장에서의 실제 활용에 도움을 주고자 하였다. Tyler의 교육과정 개발 모형에 기초하여 개발한 본 프로그램은 S초등학교 3학년을 대상으로 실시되었고, 프로그램을 개선하고 타당화하기 위해 창의성 검사, 음악적성 검사를 프로그램 실시 이전과 이후에 평가하였다. 프로그램의 실시 결과, 아동들의 창의성과 음악성은 통계적으로 유의미한 차이(p<.01)을 보이며 향상되었고, 아동들의 음악에 대한 전반적인 인식과 태도에 긍정적인 변화를 가져왔음이 입증되었다. 이는 본 연구에서 개발한 프로그램이 아동의 창의성을 신장시키고, 음악적 창의성의 기초가 되는 음악성과 음악적 흥미 및 정서를 풍부하게 하는데 효과적임을 보여주는 것이다. The purpose of this study was to develop a music education program which integrated the children's literature of fairy tales to enhance creativity in elementary school students. The 7th national music education curriculum emphasizes musical experiences to develop creativity in students and to enrich student's emotion. In doing so, a music education program which integrated fairy tales which most children are familiar to and interested in was developed. The program was developed following Tyler's model of curriculum development. It was implemented with 41 3rd grade students in S elementary School, Incheon for 7 weeks. The validation of the program was carried out using 'Creativity Test' & 'Musical Talent Test'. To measure students' interest and their classroom participation, teachers' participant observation and students' self-evaluation were made. And the results were compared with those of the control group. The results of the study are in the following: First, statistical differences(p<.01) between the experimental group and the control group were found in creativity and musical ability in students. It means the program developed in this study is good for the development of creativity and musical ability in students. Second, the results of teacher's participant observation and student's self-evaluation shows that students' emotion and attitudes toward music changed significantly in a positive way. These results that the music education program making use of fairy tales is effective to enhance creativity and musical ability in students and to enrich student's emotion.
