This study was undertaken to compare by Atomic Force Microscope the effects of various finishing and polishing instruments on surface roughness of filling and veneering composite resins. Seven composite resins were studied : Silux Plus (3M Dental Products, U.S.A.), Charisma (Heraeus Kulzer, Germany), Prisma THP (L.D.Caulk, Dentsply, U.S.A.), Photoclearfil (Kuraray, Japan), Cesead (Kuraray, Japan), Thermoresin LC (GC, Japan), Artglass (Heraeus Kulzer, Germany). Samples were placed and polymerized in holes (2mm thick and 8.5mm in diameter) machined in Teflon mold under glass plate, ensuring excess of material and moulded to shape with polyester matrix strip. Except control group (Polyester matrix strip), all experimental groups were finished and polishied under manufacturer's instructions. The finishing and polishing procedure were : carbide bur (E.T carbide set 4159, Komet, Germany), diamond bur (composite resin polishing bur set, GC, Japan), aluminum-oxide disc (Sof-Lex Pop-On, 3M Dental Products, U.S.A.), diamond-particle disc (Dia-Finish, Renfert Germany), white stone bur & rubber point( composite finishing kit, EDENTA, Swiss), respectively. Each specimens were evaluated for the surface roughness with Atomic Force Microscope (AutoProbe CP, Park Scientific Instruments, U.S.A.) under contact mode and constant height mode. The results as follows : 1. Except Thermoresin LC, all experimental composite resin groups showed more rougher than control group after finishing and polishing(p<0.1). 2. A surface as smooth as control group was obtained by $Al_{2}O_{3}$ disc all filling composite resin groups except Charisma and all veneering composite resin groups except Thermoresin LC(p<0.05). 3. In case of Thermoresin LC, there were no statistically significant differences before and after finishing and polishing(p>0.1). 4. Carbide bur, diamond bur showed rough surfaces in all composite resin groups, so these were inappropriate for the final polishing instruments.

To increase the attached gingiva and deepen the vestibular fornix, the author applied to use free gingival autograft procedure in the right premolar area in 43 years old male patients without systemic complication. Donor site for free gingival autograft procedure was determined to obtain upper palatal mucosa with Omar Paquett knife. Positioned the autograft and adaptedit firmly to the recipient site. Used a minimum number of sutures to avoid unneccessary tissue penetration. Grafted mucosa was covered with COE-pak for lweek and clinical evaluation was performed until 2 weeks after surgery. After postoperative 2 weeks, grafted mucosa was seen relatively normal gingival color and appeared like attached gingival architecture on clinical observation. During postoperative period, patient was no complain of the surgical site and periodontal eviornment of the patient was improved.

러시아어 타동사의 자동사화에 대한 고찰: -SJA 재귀동사를 중심으로

김형섭 한국러시아문학회 2015 러시아어문학 연구논집 Vol.50 No.-

This study investigates the process of detransitivization of transitive verbs in Russian. Transitive verbs, being two-place verbs, have external and internal arguments, while intransitive verbs have one external argument. The derivation of passive, antipassive, anticausative, and middle constructions presupposes transitivity within the functional projection of little vP, which is closely related to agentive theta-role and accusative case assignment in syntactic operations. Reflexive postfix ?sja in Russian plays an important role in discarding transitivity, that is, Russian postfix ?sja is employed to make passive, anticausative, antipassive, and middle constructions. Consequently, the Russian reflexive postfix ?sja is syncretic in function and meaning. Intransitive verbs divides into two groups: unergative and unaccusative. Pure reflexives indicating self-reflexives and reciprocals, antipassive belong to unergarive group whereas passive, anticausative, and middle belong to unaccusative. Russian passives are formed from imperfective verbs with the assistance of reflexive postfix ?sja and from perfective verbs with the analytic form of ``быть+past passive participle``. As English middles, Russian middles are interpreted into generic reading and potential reading, but not episodic reading. Russian middles are also formulated by reflexive postfix -sja, which is utilized to make anticausative, passive, and antipassive. Russian middles belong to type II that morphological marking is used for middles. Moreover, they also have the characteristics of type I, which requires the mandatory use of adverbs, so-called, adverbial middles. The structure of Russian middels is [S VMIDDLE+SJA *(ADV) )(*NPINSTR)], which is different from the structure of unergative of [S VUNERGATIVE+SJA (ADV) (*NPINSTR)]. Anticausative is a type of verb which also decreases the valency of argument structure by removing CAUSER argument, which can be optionally used by ``ot+NP``. In this case, NP msut be EVENT type NP, but not ENTITY type NP. Antipassive is also formed with postfix ?sja. This research encompasses the analysis on syntactic and semantic structure of detransitivized intransitives from transitive verbs, typological study, and language-universals & specifics on passive, anticausative, antipassive, and middle constructions from a perspective of morphology, syntax, and semantics.

김병호의 산조 다스름과 허튼가락 연구: 로버트 가피아스 소장자료에 기하여

김형섭 국립국악원 2020 국악원논문집 Vol.41 No.-

The following facts were discovered through analyses of the two types of melodies, that is, ‘Sanjo Dasreum’ and ‘Heoteungarak by Kim Byung Ho’ that are contained in the front and the rear of the sound source Kim Byung Ho school of Gayageum Sanjo included in Garfias’ collection. ‘Sanjo Dasreum’ is a melody played to check the tuning before playing Sanjo. It cannot be regarded as a Dasreum of an independent movement in that no rhythmic form appears, the functions of the melody do not work, and there are few interventions of articulations or vibrations. ‘Heoteungarak by Kim Byung Ho’ is the melody played on the basis of improvisation in order to fill the remaining amount of the time of the recording tape used when Garfias recorded the Kim Byung Ho school of Gayageum Sanjo remaining as recording. Transposed melodies account for at least a half of the entire melodies used, and uniquely, ghost’s wail melodies appear over seven beats. In addition, melodies that reveal the influences of the melodies of virtuosos related to Kim Byung Ho can be found. This aspect can be said to be a valuable sample that gives a glimpse of the composition method of early Sanjo virtuosos who inserted and harmonized other melodies than their original melodies when they played their melodies to make new melodies. 가피아스 소장 자료에 수록되어 있는 김병호류 가야금산조 음원의 앞과 뒤에 수록되어 있는 두 종류의 가락, 즉 ‘산조 다스름’과 ‘김병호제 허튼가락’을 분석하여 알아낸 사실은 다음과 같다. ‘산조 다스름’은 긴산조를 연주하기 전에 조율을 확인하는 용도로 연주한 가락이다. 리듬형태가 나타나지 않고 선율의 기능이 작용하지 않으며, 시김새나 농현의 개입이 거의 없는 점 등으로 보아서 단독 악장의 다스름으로 볼 수 없다. ‘김병호제 허튼가락’은 가피아스가 김병호의 가야금산조를 녹음 할 당시 녹음테이프의 남아있는 시간 분량을 채워 맞추기 위해, 즉흥을 토대로 연주한 가락이 녹음으로 남아 있는 것이다. 전체 가락의 절반 이상에 해당하는 변청 가락이 사용되고 있으며, 독특하게 귀곡성 선율이 7장단에 걸쳐 나타나고 있다. 그리고 김병호와 연관이 있는 명인들의 가락에서 받은 영향이 드러나는 가락들을 찾아 볼 수 있는데, 이러한 양상은 한 연주자가 자신의 가락을 연주할 때 본인의 독창적인 가락 이외의 가락을 본인연주에 삽입하고 융화시켜 새롭게 가락을 만들어가는 초창기 산조 명인들의 작곡방식을 엿보게 하는 귀중한 장면이라고 하겠다.

박성환,김형섭 大田産業大學校 1995 한밭대학교 논문집 Vol.12 No.0201

In this study, both a numerical investigation by finite element method and a experimental study for the analysis of stress and the characteristics of vibration in the subrack consisting of the telecommunication equipment are carried out, which its stress characteristics, a tendency and weakness of its vibration, and issues occurred in over-engineering are conducted to bring matters to basical settlements. As a numerical investigation, a general purpose computer code for structal analysys, Ⅰ-DEAS Master Series Ver. 1.3a, is used, from which stress, strain and strain energy, and displacement in the subrack are sloved. A experimental study is performed to fine out the displacement of guide support, and its results are compared with those of numerical study. Also, a natural frequency of the subrack by ZONIC FFT is experimentally measured and compard with those of natural frequency obtained from ANSYS 4.4a For the computer simulation, the locations, where the stress and displacement in the subrack are concentrated, are predicted, from which the subrack structure, based on maximum weight expected from the case of the total weight mounted on the internal side of the subrack and its concentrated loads, is visualized and reinforced by its compensated corrections. As results of a vibration analyis, the 1st mode shape affected serious factors in the vibration of the subrack are well consistent with both of a expermental and a numerical study, and it is found that its natural frquency is ranged from 27.3~36.5Hz.

김형섭 大韓神經精神醫學會 1993 신경정신의학 Vol.32 No.1

I had made a study on the cognition of and attitude toward psychiatric disorders of the military leaders because those are the important factors for the profitable and rational treatment of the soldiers. The duration of the study is 4 month(from May to July,1991) and the subjects are medical officers(general and psychiatric), military officers and staff sergeants. The results are as follows: 1) The military leaders` cognition of and attitude toward psychiatric disorders are relatively negative and rejective, and the military leaders do not expect psychiatric treatment could do much to help. 2) Non-psychiatric medical officers are relatively same with psychiatric medical officers in their cognition of and attitude toward psychiatric disorders except that they are afraid to be with psychiatric patients and they want restriction of the patients in the hospital. 3) All subjects agree to the following item; If there were a psychiatric patient in the family, the one affects the marriage of the other members. 4) Military officers and staff sergeants are more apt to assess the seperating symptoms lightly than psychiatric medical officers are and regard the suicide idea, anxiety, obsessive idea, drug abuse as same, or more serious than psychiatric symptoms.
