구윤모,김범기 한국교원대학교 과학교육연구소 1992 청람과학교육연구논총 Vol.2 No.1

본 연구는 학교에서 일반적으로 쉽게 행할 수 있는 성취도 검사로 학습내용의 논리구조가 학습자의 마음속에 발달되어 가는 과정의 심리적 측면의 이해와 수업설계에 도움이 되는 정보를 얻고자 실시하였다. 물리를 이수하는 고등학교 자연과정 남학생들(388명)을 대상으로 하였다. 축소판 GALT(group assessment of logical thinking)로 논리 사고 수준을 조사하였다. 그리고 “힘과 운동” 단원에서 선정한 6개의 개념(변위, 평균속도, 가속도, 힘, 운동량 및 충격량)에 대해 문제 맥락(직선상에서 방향 일정, 직선상에서 방향 변함, 평면상의 운동)에 따라 문항을 작성하고 논리 사고 수준별(구체적 조작기, 과도기, 형식적 조작기)로 개념의 위계구조가 어떠한 모습으로 나타나는가를 비교하였다. The purpose of this study was to find the aspects of the learner's mind, and to provide meaningful information for planning a lesson. In this study, the logical thinking of high school boys at eleventh grade was measured, and the hierarchical structures of physics concepts(displacement, average velocity, acceleration, force, momentum, and impulse) were investigated by logical thinking levels(concret operational stage, transitional, formal operational stage) in each problem context with the method of achievement test. GALT was administered before instruction, concepts understanding test after instruction. Hierarchies were determined by the level of more than 0.7(Alpha-cut) with the hierarchical coefficient on the basis of the fuzzy theory.

Formocresol을 사용한 치수절단술시 Formaldehyde의 전신적 흡수, 분포 및 급성독성에 관한 연구

이범모,한세현 大韓小兒齒科學會 1990 大韓小兒齒科學會誌 Vol.17 No.1

Formaldehyde that is active constituent in fomaocresol used in pulpotomy is known astoxic agent that causes systemic toxicity. To determine the fate of ?? -formaldehyde which was absorbed following its application to pulpotomy sites, by-pass of posterior facial vein and cannulation of external carotid artery were established with 20G-polyethylene tube. Blood samples (0.2ml) were collectd in glass syringe before the pupotomy and then at 0, 3, 5, 10, 20, 30, 45, 60, 90 and 120 minutes there-after. Plasma was separated after centrifugation at 3000xg for 15 min and aliquots of plasma were counted by liquid scintillation counter. After liver, kidney, lung, heart, spleen, muscle, and socket were removed and solubilized with tissue solubilizer, the radioactivities in solutions were counted by liquid scintillation counter. The acute toxicity of formocresol wsa determined by BUN (Blood Urea Nitrogen), GOT (Glutamic Oxalacetic Transaminase) and OCT(Ornithine Carbamyl Transferase) assay in blood samples collected at 0, 2, 4, 6, 9 and 12 hours by means of cardiac puncture. The results were as follows: 1. The radioactivity of ?? -formaldegyde reached maximal value at 3-5 minutes and decreased thereafter. 2. About 8% of ?? -formaldehyde placed in the pulpotomy site was actually absorbed systemically until 2 hours. 3. About 50% of ?? -formaldegyde absorbed actually was distributed within 20 minutes. 4. The radioactivity of organ per gram was highest in the spleen and lowest in the muscle. 5. Total radioactivity of organ was highest in the liver and lowest in the heart. 6. There were no significant differences between control and experimental groups in BUN, GOT and OCT assay.

동음이의어의 사용 양상

강범모 서울대학교 어학연구소 2005 語學硏究 Vol.41 No.1

We examine various aspects in the use of homonyms (ambiguous words) in Korean. In a comprehensive Korean dictionary, about 30% of the entries are ambiguous words and most of them are nouns. In the use of the language, 30% of the used nouns are occurrences of forms with two or more senses (not in the sense of polysemy but in the sense of homonymy). Thus lexical ambiguity might cause potential difficulty in human and computer processing of Korean. But closer examination of the usage shows that the problem of ambiguity might not be so devastating. Among ambiguous words of the same form, people use a single word (sense) most of the time. About 98% of the noun usage can be accounted for by the most frequently used word (sense) among ambiguous words. This tendency is reinforced within a discourse context, where two or more homonymous words are rarely used together. To get these and related results we collect data from and experiment on Sejong Sense Tagged Corpus (5.5 million words) and (sense tagged) Korean Modern Novel Corpus (1 million words). Results from some preliminary WSD(word sense disambiguation) experiments, which are based on collocation, frequency, and discourse contexts, are reported.

한국 영화 제목의 어휘론 : 특히 외래어 사용의 변천과 관련하여

강범모 한국어학회 2009 한국어학 Vol.42 No.-

A total of 6,800 titles of Korean films of all periods (1919-2007) Which are compiled in KMDb(Korean Movie Database) Were tagged and statistically analyzed Among other findings around 10% of alt the words in the titles are words of foreign origin When examined in terms of the 11 periods from 1919 through 2007 titles composed of only Korean native words have continuously occupied 20% of the titles except for the very early period Titles having words of foreign origin have continuously increased white the rest (titles having words of Chinese origin) have decreased An interesting observation is that the number of tides with words of foreign origin decreased temporarily during the so called IMF period (1998~2001) This suggests some implications for the relationship between social environments and the use of foreign words

FORMOCRESOL을 이용한 치수절단술시 FORMALDEHYDE의 전신적 흡수 및 급성독성에 관한 연구

이범모,한세현,김관식,정동균 대한구강생물학회 1990 International Journal of Oral Biology Vol.14 No.1

Formaldehyde that is active constituent in formocresol used in pulpotomy is known as toxic agent that causes systemic toxicity. To determine the fate of the ^14C-formaldehyde which was absorbed following its application to pulpotomy sites, by-pass of posterior facial vein and cannulation of external carotid artery were established with 20G-polyethylene tube. Blood samples (0.2ml) were collected in glass syringe before the pulpotomy and then at 0, 3, 5, 10, 20, 30, 45, 60, 90 and 120 minutes thereafter. Plasma was separated after centrifugation at 3000 x g for 15 min and aliquots of plasma were counted by liquid scintillation counter. After liver, kidney, lung ,heart, spleen, muscle, and alveolar socket were removed and solubilized with tissue solubilizer, the radioactivities in solutions were counted by liquid scintillation counter. The acute toxicity of formocresol was determined by BUN, GOT and OCT assay in blood samples collected 0, 2, 4, 6, 9 and 12 hours by means of cardiac puncture. The results were as follows ; 1. The radioactivity of ^14C-formaldehyde reached maximal value at 3-5 minutes and decreased thereafter. 2. About 8% of ^14C-formaldehyde placed in the pulpotomy site was actually absorbed systemically until 2 hours. 3. About 50% of ^14C-formaldehyde absorbed actually was distributed within 20 minutes. 4. The radioactivity of organ per gram was highest in the spleen and lowest in the muscle. 5. Total radioactivity of organ was highest in the liver and lowest in the heart. 6.

생성어휘부 이론의 다의어 기술 방법과 그 적용 : 동사 '사다'와 '팔다' With reference to Korean Verbe Sada 'to buy' and palda 'to sell'

강범모 서울대학교 어학연구소 2002 語學硏究 Vol.38 No.1

In the theory of Generative Lexicon, polysemy is not handled by the sense enumeration method, the traditional means of description in lexicography. Instead, it uses various generative mechanisms such as cocomposition, type coercion, and selective binding. Such generative devices operate on rich lexical representations incorporating event structure, argument structure and qualia structure. After reviewing those mechanisms with many Korean examples, I extend the generative lexicon analysis to Korea verbs of transaction, sada ("to buy") and palda ("to sell"). Only those senses which are regularly, or productively related will be targets of unified description.

Quantificational Determiners and Distributive Predicates

( Beom-mo Kang ) 한국언어정보학회 1998 언어와 정보 Vol.2 No.1

It has been suggested in the linguistics literature that quantification and distributivity are closely related phenomena and some linguists claimed that distributivity should be classified in terms of distributivity. I suggest, on the empirical grounds, that distributivity is essentially a phenomenon over (one-place) predicates in a broad sense. (Korea University)

Comparison of the Effectiveness of Sling Exercise and McKenzie Exercise in Patients with Acute Cervical Whiplash Associated Disorder Following Rear-end Collision

( Mo-beom Jeong ),( Jae-yun Kim ),( Dong-woo Lee ) 대한물리치료학회 2016 대한물리치료학회지 Vol.28 No.5

Purpose: This study compared the effectiveness of sling exercise and McKenzie exercise in patients with acute cervical whiplash associated disorder (WAD) caused by rear-end collision. Methods: Thirty WAD patients were randomly assigned to one of three groups; a sling exercise (SE) group, a McKenzie exercise (McE) group, and a control group. Members of the SE and McE exercised three times a week for four weeks under the researcher`s guidance. Three groups performed TENS treatment three times a week for four weeks. Diagnostic radiological equipment was used to measure whiplash injury. Visual analog scale (VAS), neck disability index (NDI), and range of motion (ROM) were used in this study. Results: The three groups showed a significant pre-post treatment difference in measures of VAS and NDI (p<0.05). The SE group showed a significant pre-post treatment difference in measures of flexion and extension changes compared to the McE and control group (p<0.05). The SE group also showed significantly greater improvement in the VAS, NDI, and ROM changes than the control group (p<0.05). Conclusion: These findings indicate that sling exercise is a stronger and more aggressive intervention for treatment of acute WAD patients.

Beom Mo Kang,Seok Mann Yoon,Jae Sang Oh,Hyuk Jin Oh,Jae-Min Ahn,Gi Yong Yun 대한뇌혈관외과학회 2023 Journal of Cerebrovascular and Endovascular Neuros Vol.25 No.2

Objective: Carotid artery stenting (CAS) is currently widely used for the treatment of carotid artery stenosis. The objective of this study was to analyze the outcomes of CAS performed in a single institution.Methods: We retrospectively analyzed 313 CAS cases from January 2007 to December 2020, including 206 (66%) symptomatic and 107 (34%) asymptomatic cases. Procedure-related morbidity and mortality were assessed. Rates of periprocedural (≤30 days after CAS) and postprocedural ipsilateral strokes (>30 days after CAS) were also assessed. Logistic regression analysis was used to identify risk factors for the periprocedural complication, in-stent restenosis (ISR), and ipsilateral stroke.Results: The success rate of CAS was 98%. Among 313 cases, 1 patient died due to hyperperfusion-related intracerebral hemorrhage (ICH). The CAS-related mortality rate was 0.31%. The overall incidence of periprocedural complications is 5.1%. A risk factor for periprocedural complication was a symptomatic carotid artery stenosis (7.3% vs. 0.9%, p=0.016). Twenty cases of ISR occurred during 63.7±42.1 months of follow-up. The overall incidence of ISR was 10.2% (20/196). A risk factors for ISR were diabetes mellitus (17.6% vs. 5.7%, p=0.008) and patients who used Open-cell stents (19.6% vs. 6.9%, p=0.010). The overall incidence of ipsilateral stroke is 5.6%. A risk factors for ipsilateral stroke was ISR (95% CI, p=0.002).Conclusions: CAS is a safe and effective procedure for carotid artery stenosis. Although the incidence of complications is low, fatal complication such as hyperperfusion- related ICH can occur. To prevent hyperperfusion-related ICH, several methods such as strict blood pressure (BP) control, intentional less widening of stenotic segment should be used. To prevent ISR or stroke occurrence, special attention should be paid to patients who have ISR or ipsilateral stroke risk factors.

Markup of Korean Dictionary Entries

( Beom Mo Kang ) 한국언어정보학회 1996 국제 워크샵 Vol.1996 No.-

Dictionary markup (encoding) is one of the concerns of TEI (Text Encoding Initiative), an international project for text encoding. In this paper, we investigate ways to use and extend TEI encoding scheme for the markup of Korean dictionary entries. Since TEI suggestions for dictionary markup are mainly for western language dictionaries, we need to cope with problems to be encountered in encoding Korean dictionary entries. We try to extend and modify the TEI encoding scheme in the way suggested by TEI. Also, we restrict the content model so that the encoded dictionary might be viewed more as a database than as a simple computerized, originally printed, dictionary.
