Purpose: The purpose of this study was to define the relation of the degree of menton deviation and 3-D CT (computerized tomography) measurements of the glenoid fossa and the mandible, which are considered to have an influence on menton deviation. Methods: The CT images were obtained in 60 adults and these were transmitted to a computer and reconstructed using computer software. According to the degree of the menton deviation, which was measured on the posteroanterior cephalogram, the subjects were divided into the menton deviated group (30 adults) and the symmetry group (30 adults). A total of 11 measurements that might have an effect on menton deviation were determined and these were measured in the right and left sides using the function of 3-D measurement in the computer program. The 11 measurements consist of 6 measurements in the glenoid fossa (vertical position of the glenoid fossa and articular eminence, the sagittal position of the glenoid fossa and articular eminence, the depth of the glenoid fossa, and the anterior angle of the glenoid fossa), and 5 measurements in the mandible (ramus length, frontal ramal inclination, lateral ramal inclination, body length, body height). Results: The comparison of the differences between the menton deviated and symmetry groups and correlation analysis on the degree of menton deviation were carried out. The results of comparison of the right and the left difference between the menton deviated and symmetry groups showed that the vertical position and depth of the glenoid fossa were significantly increased in the menton deviated group. Conclusion: The results of the present study show that consideration of the shape and position of the glenoid fossa is necessary for making the diagnosis and administering proper treatment in facial asymmetry patients and especially growing patients.

조진형,전영주,이라함,심정현,채정일,Cho, Jin-Hyoung,Jeon, Young-Joo,Lee, Ra-Ham,Shim, Jung-Hyun,Chae, Jung-Il Korean Association of Organic Agriculture 2014 韓國有機農業學會誌 Vol.22 No.1

Korean Panax ginseng C. A. Meyer (P. ginseng) is a well-known and one of the most important tonic herbs used in traditional Korean medicine. The pharmacological effects of P. ginseng have been reported by many researchers. Nevertheless, little is known between the mechanism of action and the active compounds. In this study, we performed a comprehensive proteomic analysis and protein categorization in order to understand the physiological characteristics of the major components in the adventitious roots of P. ginseng. Whole proteins extracted from the cultured adventitious roots of P. ginseng were separated by two-dimensional polyacrylamide gel electrophoresis (2-DE). Among the 1000 spots which were detected by silver staining, 113 spots were labeled and identified by matrix-assisted laser desorption/ionization-time of flight-mass spectrometry (MALDI-TOF MS). Our results showed that 40 proteins were identified among the 113 spots, with a hit ratio of 35.3%. A number of proteins identified on the 2-DE gels (30%; 16 spots) were involved in energy metabolism. These proteomic data will be helpful to better understand the physiological and pharmacological effects of P. ginseng.

Transverse mandibular deficiency has a many problem in growing patients. Therefore, Mandible symphysis widening is recommended. A new surgical technique has been developed to widen the mandible. The purpose of this study is to report the effect of mandibluar symphyseal distraction osteogenesis by use of bone-borne type distractor. The surgical procedure was accomplished under general anaesthesia with step-line osteotomy. Bone-borne type distractor was used to generally widen the mandible. The expansion achieved in the mandible was 8.31mm at the device, 6.32mm at the canines, 4.06mm at the first molars. The symphyseal distraction gaps were bridged by new bony regeneration. Mandibular symphseal distraction osteogenesis increased mandibular arch width, stabilized occlusion, and corrected dental crowding.

조진형(Cho, Jin-Hyoung),서유석(Seo, Yu-Seok) 북한학회 2015 북한학보 Vol.40 No.1

최근 우리사회는 고등학교 역사교과서에 대한 논쟁으로 홍역을 앓고 있다. 논점은 주로 검인증제하에서의 8종 역사교과서에 기술되어 있는 근현대사 부분의 이념적 편향성에 관한 부분이다. 이러한 문제는 최근 역사교육의 중요성이 강조되면서 2017년부터 한국사영역이 수능필수과목으로 지정되는 것과 무관치 않다. 고교 역사교과서의 이념논쟁이 불붙으며 2014년 8월과 9월 교육부 주최로 두 차례의 정책토론회에 진행되었다. 특히 이슈가 되고 있는 부분은 구한말부터 현대사까지의 기술부분으로 통일과 북한에 대한 기술에 포커스가 맞추어져 있다. 본 고에서는 8종 고교역사교과서의 통일․북한 분야의 기술내용을 중점적으로 분석했다. 현재 교육중인 8종 역사교과서의 통일․북한 파트의 구성과 서술 분석을 통해 그 문제점을 검토하고 우리나라 역사 교육의 대안적 방향을 제시했다. Recently, our society is suffering from measles controversial history textbook for high school. The issue is part of the ideological bias of modern and contemporary history section, which is mainly technical in eight kinds of textbook. These issues while emphasizing the importance of the recent history of Korean history education since 2017 this area is not unrelated to that specified by the SAT required courses. In particular, part of which has been an issue becomes the focus is on technologies tailored for the unification with North Korea as part of the technology to the modern history from the Late period of Chosun. This paper analyzed eight kinds of technical information of a unified North Korea it focuses on the field of high school history textbooks. Review the description and analysis of the problem through the construction of a unified North Korea being part of the current eight kinds of education and history textbooks have presented an alternative way of teaching Korean history.

일반논문 : 유교문화, 경제적 요인이 일제하 초기공산주의 운동에 미친 영향

조진형 ( Jin Hyoung Cho ) 동국대학교 북한학연구소 2013 북한학연구 Vol.9 No.2

일반적으로 정치 운동가들의 참여 동기와 사상과 노선의 성격을 분석하는 것 은 그들과 그들의 소속단체의 정체성과 역량을 평가하는데 도움이 된다. 이런 관 점에서 1920년 이후 일제 식민지하에서 조선공산주의 운동에 참여한 사람들의 사회 경제적 배경을 살펴보는 것은 조선공산주의 운동의 성격과 한계성을 파악 하는데 매우 중요하다. 본고에서는 일제하 공산주의 운동 참가자들의 참여 동기 와 사상 전향자들의 전향동기를 분석한 결과 전통적 유교 문화와 가치관이 초기 공산주의 운동의 외연적 확산에 긍정적인 영향을 주었음을 주장하고자 한다. 공산주의 운동에 참여하였던 적극가담자들의 참여 동기 중 개인적 또는 집단 적 교제, 즉 한국의 전통적 유교 문화에 기반을 둔 관습적 혈연·지연·학연 등 에 의한 경우가 많았던 것과 이후 사상 전향자들의 전향 동기 중 에서도 가족애 (부모에 대한 효도, 가족부양 및 가족연대 의식 등)가 적지 않았다는 점에서 조 선공산당 결성에는, 개인 친교와 조직과의 유대관계, 효와 가족에 대한 부양 책 무를 중시하는 전통적 유교 문화와 가치관이 초기 공산주의 운동 과정에서 인맥 을 통한 외연적 조직 확산과 조직 유대 강화에 기여했다고 본다. 그러나 이같은 유교적 문화와 가치관이 사상 전향 과정에서는 오히려 공산주 의 투쟁의지를 와해시키고 전향을 촉진하는 역할을 하는 양날의 칼로 작용했으 며, 또한 혈연과 지연 등 개인적 인적 관계를 중심으로 한 조직 특성상 태생적으 로 조기공산주의의 분파성이 나타날 수밖에 없었다. 한편 1920년대 이후 식민경 제의 피폐에 영향을 받아 유교적 가치관과 문화가 급속히 붕괴되는 과정에서 반 유교적 기치를 내세우던 여성단체들의 활동이 본격화되어 민족 의식을 바탕으로 항일 독립 운동으로 전환되었다는 점에서 유교적 가치와 문화는 붕괴 과정에서 도 새로운 항일운동의 계기를 마련했다고 평가할 수 있을 것이다. 결론적으로 일제하 초기 공산주의 운동이 전개되는 과정에서 전통적 유교 문 화와 가치관은, 구성원 간의 유대 강화와 외연적 조직 확산에 중요한 매개체 역 할을 수행했으며, 1920년 이후 유교 가치관·문화가 붕괴되는 과정에서도 반작 용으로서 여성 항일 운동의 시발점이 된 여성 해방 운동의 탄생을 가져오게 했다 는 점, 조선공산주의 운동가들의 전향과정에서는 오히려 총독부의 사상 전향 공 작 수단으로 악용되었다는 점에서 민족적 특성으로서 항일 운동에 미친 중요한 영향 요소로 평가되어야 한다. Generally speaking, the analysis on political activists’ motivation and ideology and nature of their political lines help to evaluate the identity and performance of their movement. In this respect, the study of socioeconomic background of those who have participated in Chosun Communist movement under Japanese colonial rule since 1920s is very important in understanding the nature of Chosun Communist movement. Analysis on the motivation of participants in Communist movement and the reason for political turncoats swtiching ideologies seems to prove that traditional Confucian culture and values have had positive effect on supeficial proliferation of early Communist movement. In that active participants in early Communist movement are largely motivated by personal or collective association, namely, customary bloody ties, territorial relationship, educational background, etc. and political turncoats are heavily influenced by family affection(filial duty to parents, support for family, and family ties, etc.), the combination of traditional Confucian culture, ethic, and values seems to have been involved in the formation of Chosun Communist party and to have acted as important agent in the process of superficial organizational proliferation and dissolution. In other words, private association, organizational ties, and traditional Confucian culture and values that attach importance ro love towards parents and responsibility for supporting family seem to have contributed to apparent organizational proliferation and the strengthening of structural ties during the early Communist movement. These Confucian culture and values, however, weakened willingness to struggle against Communism in the process of changing ideologies and accelerated conversion to pro-Japanese, and early Communism had to have factional tendency because it was based on organizational characters which were personal relationships such as bloody ties and territorial relationship. On the other hand, in that in the process of corrosion of Confucian values and culture influenced by devastation of colonial economy since 1920s, women’s organizations advocating female equality, supporting anti-Confucianism, have done their activity more seriously and their activity eventually have turned into independence movement against Japanese colonial rule based on national awareness, it could be evaluated that Confucian values and culture, while being destroyed, produced new ideology against Japan. In conclusion, in that in the process of early Communist movement, traditional Confucian culture and values functioned as important media for strengthening ties between members and apparently proliferating org anizations, in the process of their collapse since 1920s have produced women``s liberation movement, the starting point of women’s independence movement against Japanese colonial rule, and the traditional values and culture were misused by the Japanese Government General of Chosun in the process of conversion of Chosun Communist activists, traditional Confucian culture and values should be evaluated as a crucial factor with which national charactrics had an effect on struggle against Japanese colonial rule.

최학희,조진형,박홍주,오희균,최진휴,황현식,이기헌,Choi, Hak-Hee,Cho, Jin-Hyoung,Park, Hong-Ju,Oh, Hee-Kyun,Choi, Jin-Hugh,Hwang, Hyeon-Shik,Lee, Ki-Heon 대한악안면성형재건외과학회 2009 Maxillofacial Plastic Reconstructive Surgery Vol.31 No.2

Purpose: This study was to evaluate the validity of superimposition range at facial images constructed with 3-dimensional (3D) surface laser scanning system. Materials and methods: For the present study, thirty adults, who had no severe skeletal discrepancy, were selected and scanned twice by a 3D laser scanner (VIVID 910, Minolta, Tokyo, Japan) with 12 markers placed on the face. Then, two 3D facial images (T1-baseline, T2-30 minutes later) were reconstructed respectably and superimposed in several manners with $RapidForm^{TM}2006$ (Inus, Seoul, Korea) software program. The distances between markers at the same place of face were measured in superimposed 3D facial images and measurement were done all the 12 makers respectably. Results: The average linear distances between the markers at the same place in the superimposed image constructed by upper 2/3 of the face was $0.92{\pm}0.23\;mm$, in the superimposed image constructed by upper 1/2 of the face was $0.98{\pm}0.26\;mm$, in the superimposed image constructed by upper 1/3 of the face and nose area was $0.99{\pm}0.24\;mm$, in the superimposed image constructed by upper 1/3 of the face was $1.41{\pm}0.48\;mm$, and in the superimposed image constructed by whole face was $0.83{\pm}0.13\;mm$. There were no statistically significant differences in the liner distances of the makers placed on the area included in superimposition range used for partial registration methods but there were significant differences in the linear distances of the markers placed on the areas not included in superimposition range between whole registration method and partial registration methods used in this study. Conclusion: The results of the present study suggest that the validity of superimposition is decreased as superimposition range is reduced in the superimposition of 3D images constructed with 3D laser scanner for the same subject.

김윤상,조진형,Kim, Yun-Sang,Cho, Jin-Hyoung 대한치주과학회 2008 Journal of Periodontal & Implant Science Vol.38 No.2

Purpose: These case reports show the orthodontic treatment of lower anterior incisors with gingival recession. Materials and Methods: Three cases were treated by an orthodontist and a periodontist. Each case had lingually tilted lower anterior incisors, anterior crossbite and skeletal Cl III pattern. Results: A variety of etiological factors were thought to cause gingival recession: aging, oral hygiene, tooth malpositioning, occlusal trauma. Conclusion: Due to the interaction among many possible contributing factors, it is difficult to predict whether further gingival recession may occur at a given site. The position and the movement of the lower anterior incisors with gingival recession are important factors in diagnosis and orthodontic treatment planning.

장나영,조진형,이유미,강경화,Chang, Na-Young,Cho, Jin-Hyoung,Lee, You-Mee,Kang, Kyung-Hwa Korean Academy of Orofacial Pain and Oral Medicine 2009 Journal of Oral Medicine and Pain Vol.34 No.3

The purpose of this study was to evaluate the soft tissue changes of class II adolescents and adults in respect to extraction or nonextraction. The study included 68 patients from Wonkwang Dental Hospital were categorized to adolescent extraction group, adolescent nonextraction group, adult extraction group, adult nonextraction group. Cephalometric tracing of each patient was done to compare pretreatment and posttreatment of each group, to compare the changes between groups. And among the variables that showed significancy, correlation analysis and simple linear regression were done. The results were as follows. 1. In both adolescents and adults after extraction treatment, nasolabial angle significantly increased and in both subjects after non extraction treatment, nasolabial angle significantly decreased. 2. In extraction subjects, there were positive correlation between the amount of treatment changes of vertical-U1 and E line-upper lip, the changes of vertical-L1 and E line-lower lip, the changes of vertical-L1 and vertical-Li. 3. In extraction subjects, simple regression equations of E line-upper lip, E line-lower lip, Li were calculated by regression analysis. According to the results above, it could be considered that the effect of the extraction or nonextraction treatment was greater than the effect of growth.
