This study intends to test the effect of cyber victimization on cyber offending and investigates which variables operate moderating effects. This study uses six moderating variables such as low self-control, attitudes toward cyber delinquency, parental support, peer support, self-esteem, and the perceived opportunity of cyber delinquency. Using data from 353 elementary, middle, and high school student in Kyunggi area, the study tests the interaction effects of cyber victimization and moderating variables on cyber offending. Results show that the interaction effect between cyber victimization and low self-control is not significant. However, the interaction effect between cyber victimization and attitude towards cyber delinquency is positively significant. In addition, the interaction effect between cyber victimization and peer support is negatively significant, while the interaction effect between cyber victimization and parental support is positively significant. It is also found that the interaction effect between cyber victimization and self-esteem is negatively significant. It is revealed that the moderating effect of the perceived opportunity is the most significant. The policy implications are discussed.

용헌(容軒) 이원(李原)의 역사의식

정성식 ( Jeong Seong-sik ) 한국철학사연구회 2017 한국 철학논집 Vol.0 No.55

본 논문의 목적은 고려 말 조선 초기에 활동한 용헌 이원의 역사의식을 재조명하는 데 있다. 그는 권근의 학문적 영향으로 유교사상에 많은 관심을 가지게 되었다. 그는 유학적 정치의식과 공의적 가치관에 기반하여 나라를 근심하고 백성을 구휼하려하였다. 이러한 자세로 당시 국가운영 시스템을 정비하며 민생안정을 도모하는 데 많은 관심과 노력을 기울였다. 이원은 이성계에게 상소문을 올려서 한 시대의 본보기가 될 만한 열 가지의 준칙을 제시하였다. 이원의 유학사상은 정치현실에 있어서 ‘신의’의 문제를 중시하는 모습으로 나타났다. 여기서 정치적 신뢰성을 원론적으로 강조하며 중시한 이원의 유학적 정교이념을 확인할 수 있다. 이원은 당시 사회제도의 문제점을 지적하고 이의 시정을 위해 적극적으로 힘을 기울였다. 다양한 건의를 통한 많은 정책들은 모두 그의 유교적 정치사상을 실현하는 데에 그 최종 목적을 둔 것이었다. 이원의 역사의식은 사상적으로 유교적 정교이념들을 기반으로 하여 전개되었다. 이는 조선 초기의 국가운영 시스템 정비와 사회적 과제들을 해결해나가는 데 있어서 일정한 역할을 수행한 것으로 그 의의를 부여할 수 있다. The purpose of this thessis is to reflect the historical awareness of Yonghun Lee-Won, who was originally active in the late Koryo and he early Chosun period. With the scholarly influence of Kwon-Geun, he became very interested in Confucianism. Based on his confucian political consciousness and moral values, he sought to help the nation and relieve the public. In this posture, he focused on improving the national operating system and making efforts to stabilize the people's livelihood. Lee-Won presented the articles to Yi Seong-gye and presented 10 principles to set an example of an era. Lee-Won' Confucian ideas showed a serious aspect of the issue of faith in politics. Here he can check his Confucian politics. Lee-Won pointed out the problems of the social system at the time and actively applied for improvements. Many of the various proposals were aimed t realizing his Confucian ideology. Lee-Won' historical awareness was developed consistently based on Confucian ideology. This can be acieved by playing a certain role in solving the national operating system maintenace and social tasks of the early Chosun period.

OK-432(Picibanilⓡ)와 외과적 절제술을 이용한 선천성 림프관종의 치험례

김일규,이성호,오성섭,최진호,오남식,김왕식,임영일,양동환 대한악안면성형재건외과학회 2001 Maxillofacial Plastic Reconstructive Surgery Vol.23 No.3

Lymphangiomas are relatively rare benign tumors of the lymphatic system, characterized by congenital lymphatic malformation such as anastomosis or obstuction of the lymphatic channels. There are most frequently diagnosed in children younger than 3years. In contrast to that of the hemangioma, the sex distribution of the lymphangioma is nearly evenly divided. The head and neck lymphangioma represents about 70∼75% of all lymphangiomas, and they are difficult to manage. Spontaneous regression is rare, and rapid intermittent enlargement occurs secondary to infection or trauma. Enlargement may cause serious sequelae such as airway obstruction, feeding difficulties, and cosmetic problems. Treatments previously used for lymphangiomas include surgical excision and intralesional injection of sclerosants. Problems associated with surgical excision include the risk of cosmetically unacceptable scarring and the risk of damage to surrounding vital stricture and the high risk of incomplete excision. The sclerosants previously used have numerous other local and systemic side effects. This report describes a case that was successfully treated using OK-432 as a new sclerosant drug and secondary surgical excision for congential cavenous lymphangioma extensively enlarged to tongue, mouth floor and submandibular region.

골격성 Ⅲ급 부정교합자의 두개안면골격형태가 하악이부형태와 하악전치의 위치에 미치는 영향을 알아보고자 연구를 시행하였다. 전후방적인 악골부조화가 나타나지 않고 교정치료의 경험이 없는 만 20세 이상의 성인남녀(정상군)와, 하악전돌의 악골부조화를 보이며 교정치료의 경험이 없는 만 20세 이상의 성인남녀(하악전돌군)를 비교하여, 두개안면골격형태에 따른 하악이부형태와 하악전치의 위치에 관하여 다음과 같은 결론을 얻었다. 1. 두개안면골격형태의 비교에서 하악에 관련된 ∠SN-Mn, ∠FMA, ∠Pal-Mn, ∠LFH은 하악전돌군이 정상군에 비하여 크게 나타났지만, (p<0.05) 상악에 관련된 항목은 차이를 나타내지 아니하였다(p>0.05). 2. 하악전치를 둘러 싸고 있는 치조돌기는 하악전돌군이 정상군에 비해서 수평적으로 좁고, 수직적으로 긴 형태를 나타내었다(p<0.05). 하악이부의 형태에서도 수평적으로는 하악전돌군이 정상군에 비해서 좁게 나타났으나, 수직적으로는 차이를 나타내지 아니하였다(p>0.05). 3. 하악전돌군의 두개안면골격형태와 이부계측항목과의 상관관계에서 두개저와 하악하연에 기인하는 수직적인 악골부조화가 증가할수록 LaABH, LiACBW, LaACBW, LiABBW, SW, ∠LISA가 감소하는 역상관계를 나타냈지만(p<0.05), 전후반적인 악골부조화와는 별다른 상관관계가 나타나지 않았다(p>0.05). 4. 하악전돌군에서 수직적인 두개안면골격형태를 나타내는 ∠SN-Mn, ∠FMA, ∠Pal_Mn, ∠LFH와 하악이부의 계측항목인 ∠LiACBW. LiaBBW, SW, ∠LISA사이에 높은 상관관계가 존재하여, 수직적인 악골부조화로 하악이부의 형태와 하악전치의 경사도를 예측할 수 있었다(p<0.001). The purpose of this study was to evaluate the morphology of mandibular symphysis and location of lower incisor under the influence of the craniofacial skeleton in skeletal Class III malocclusion. The sample consisted of 132 adults who have severe Class III malocclusion (prognathism group, 33 males and 33 females), and who have normal occlusion (normal group, 33 males and 33 females). They had not received any orthodontic treatment or orthognathic surgery. The lateral cephalograms were evaluated. The results were as follows: 1. Prognathism group were larger than normal group in comparison of facial skeleton (p<0.05) with the exception of ∠FH-Pal, ∠SNA. 2. In the morphology of symphysis, measurements of anteroposterior width(LaABBW, LiABBW, SW) of prognathism group were significantly less than that of normal group(p<0.001). 3. In the correlative analysis between the craniofacial skeleton and symphysis measurements of prognathism group, vertical measurements in relation with cranial base and mandibular plane showed reverse correlationship with anteroposterior with of symphysis(LiACBW, LaACBW, LiABBW, SW)(p<0.05). But, there was not distinct difference between horizontal skeletal measurements and symphysis measurements(p>0.05). 4. The probability by regression test between vertical measurements(∠SN-Mn, ∠FMA, ∠Pal-Mn, ∠LFH) and symphysis measurements(LiACBW, LiABBW, SW, ∠LISA)were very high(p<0.001).

While braking cars, a large amount of energy is taken into the brake system in a short period of time. This leads to some problems ; cracking of the disc, non-uniform wear of pad and disc, fade. Thus it is important to measure the contact thermal behaviour precisely between disc and pad. The measurements must be considered to design the brake system. The paper describes methods to analysis the problem of the thermal behavior on the ventilated disc with ANSYS-a program of FEA and a brake dynamometer. According to this way, the paper can present the error between the data by the dynamometer and the results of analysis by ANSYS.

The purpose of this report is to present the successful improvement of occlusal relationship and facial esthetics in class Ⅱ division 1 malocclusion with severe labioversion of upper anterior teeth and severe overjet, and in class Ⅱ malocclusion with infraversion of bilateral maxillary canines by MEAW mechanics, which enables us to get effective distal en mass movement of maxillary dentition, with upper second molar extraction. After treatment, there were natural contact points at canine and premolar regions, normal occlusal relationship and treatment results, satisfied the gnathologic concept, in this 2 cases. Compared with the routine treatment with premolar extraction, the treatment time and patients' discomfort were reduced. And the MEAW mechanics, which enables us to get effective distal en mass movement of maxillary dentition, resulted in reduction of the treatment time and getting the good treatment results. Consequently, the major concerns in orthodontic treatment are appropriate diagnosis and treatment plan, so, the application of second molar extraction with appropriate case analysis and diagnosis is very helpful to orthodontic treatment.

홍성일,김영민,변건식 東亞大學校 附設 情報通信硏究所 1996 情報通信硏究所論文誌 Vol.4 No.1

When GPS(Global Positioning System) is used as synchronous signal in CDMA digital cellular base station system and high speed digital synchronous communication network, antenna cable lengh is increased, comparing with other GPS application such as positioning or car navigation. In this paper, it is proposed that a type of new GPS antenna system including RF stage for reduction of cable loss in case of long cable. The antenna system with TMPA(Truncated-corners Microstrip Patch Antenna) is designed and fabricated because GPS signal has RHCP(Right-Hand Circular Polarization), consequently antenna size can be made small size. NAN(Low Noise Amplifier) is designed by using HEMT(High Electron Mobility Transistor) which has lower noise figure and better AGC characteristics at low voltage than GaAs FET, and we equipped mixer, in GPS antenna unit, which converts from 1575.42MHz to 75.42MHz. As result of comparing between typical system and proposed system when cable length is 60m, 63dB, 55dB and 25dB gain are obtained for RG-316/U, RG-58C/U and RG-213/U, and better characteristics are achieved than typical system as far as cable length is longer.
