      • 김삿갓의 자아 찾기, 웃음과 울음

        김준형 ( Kim Joon-hyeong ) 동방비교연구회 (구 한국동방문학비교연구회) 2016 동방문학비교연구 Vol.6 No.-

        김립은 `시`를 통해 자신의 존재 이유를 찾았다. 그의 시는 때로는 비유적으로, 때로는 직설적으로 세상에 대해 말한다. 욕설과 조롱의 시. 그 때문에 그는 학자들에게 비판을 받기도 했다. 그러나 우리가 주목해야 점은 욕설과 조롱 자체가 아니다. 오히려 그 이면에 담긴 김립의 사유가 더 중요하다. 노골적인 웃음 뒤에 감춰진 서글픈 자기 연민. 이 글에서 주목한 키워드다. 김립의 방랑은 개인적 분노에서 출발한다. 시간이 지나면서 그 분노는 사회로 향했다. 사회적 모순에 대한 분노가 크지만, 그는 아무 것도 할 수 없다. 그런 자신에 대한 부끄러움도 커졌다. 그의 시에 등장하는 사회에 대한 공격, 민중에 대한 애정, 자아 성찰은 이런 배경에서 만들어졌다. 특히 그의 시를 지배하는 웃음은 그 이면에 주목할 필요가 있다. 한바탕 웃고 넘어가면 그만인 작품 뒤에 숨겨진 통곡. 그것은 탈출구조차 찾지 못한 김립 시의 실체이기 때문이다. 그의 시가 울분의 시대를 살았던 식민지 지식인들 사이에서 널리 애송되었다는 점도 그와 맥을 같이 한다. The Joseon Dynasty poet Kim Lib (金笠) found his raison d`etre through poetry. Popularly known as “Kim Sat-gat the Wandering Minstrel,” Kim Lib, or Kim Byeong-yeon (金炳淵, 1807~ 1863) as his real name, speaks of the world sometimes metaphorically or sometimes bluntly. Because he wrote poems of profanity and mockery, he was often criticized by scholars. But, what should be noted as important is not profanity or mockery per se but the poet`s personal reason behind his works. The keyword is sad self-pity hidden behind obvious laughter. Kim Lib`s wandering started from personal rage. As time passed by, the rage was directed towards society. He was angry against social contradiction but he could not do anything. His sense of shame toward himself grew larger. His attack against society, affection for people and self-examination appearing his poems were made from such a background. Laughter in particular that dominates Kim`s poems should be noted in this regard. Behind the poems inviting simple bursts of laughter are wails of pain. That is the true nature of Kim Lib who could not find his way out.

        돼지감자꽃의 예쁜꼬마선충 내의 항산화 효과

        김준형,이예빈,한선여,김수진,황인현,김대근,Kim, Jun Hyeong,Lee, Ye Bin,Han, Seon Yeo,Kim, Su Jin,Hwang, In Hyun,Kim, Dae Keun 한국생약학회 2019 생약학회지 Vol.50 No.2

        Methanol extract of Helianthus tuberosus L. (Compositae) flower was investigated to research the anti-oxidative activity by using a Caenorhabditis elegans model system. Ethyl acetate soluble fraction of the methanol extract showed the most potent DPPH radical scavenging activity. The ethyl acetate fraction was measured on its activities of superoxide dismutase (SOD), catalase, and oxidative stress tolerance with reactive oxygen species (ROS) level in C. elegans. Furthermore, in order to verify if regulation of stress-response gene is responsible for the increased stress tolerance of C. elegans which treated by the ethyl acetate fraction, we checked SOD-3 expression using a transgenic strain. Consequently, the ethyl acetate fraction of H. tuberosus flower increased the catalase and SOD activities in a dose-dependent manner in C. elegans, reduced ROS accumulation dose-dependently. Besides, the ethyl acetate fraction-treated CF1553 worms showed higher SOD-3::GFP intensity than the control group.

        Pd 첨가량 및 첨가방법이 알코올 센서용 SnO<sub>2</sub> 반도체 후막 특성에 미치는 영향 연구

        김준형,김형관,이호년,김현종,이희철,Kim, Jun-Hyung,Kim, Hyeong-Gwan,Lee, Ho-Nyun,Kim, Hyun-Jong,Lee, Hee-Chul 한국표면공학회 2017 한국표면공학회지 Vol.50 No.5

        In this paper, two methods of making the Pd-added $SnO_2$ ($Pd-SnO_2$) powder with pure tetragonal phase by the hydrazine method were suggested and compared in terms of crystal structure, surface morphology, and alcohol gas response. One of the addition methods is to use $PdCl_2$ as a Pd source, the other is to use Pd-based organic with oleylamine (OAM). When Pd concentration was increased from 0 to 5 wt%, the average grain size of $Pd-SnO_2$ made with Pd-OAM were decreased from 32 to 12 nm. In the case of using with $PdCl_2$, grain size of the $PdCl_2$ fell to less than 10 nm. However, agglomerated and extruded surface morphology was observed for the films with Pd addition over 4 wt%. The crack-free $Pd-SnO_2$ thick films were able to successfully fill the $30{\mu}m$ gap of patterned Pt electrodes by optimized ink dropping method. Also, the 2 wt% $Pd-SnO_2$ thick film made with PdCl2 showed gas responses ($R_{air}/R_{gas}$) of 3.7, 5.7 and 9.0 at alcohol concentrations of 10, 50 and 100 ppm, respectively. On the other hand, the prepared 3 wt% $Pd-SnO_2$ thick film with Pd-OAM exhibited very excellent responses of 3.4, 6.8 and 12.2 at the equivalent measurement conditions, respectively. The 3 wt% $Pd-SnO_2$ thick film with Pd-OAM has a specific surface area of $31.39m^2/g$.

        아스팔트포장의 수명 및 공용성 확보를 위한 품질관리 대책의 하나로 아스팔트포장 포설면의 온도 불균형(Thermal Segregation) 현상 최소화를 위하여 균질한 다짐밀도를 확보하기 위한 연구가 미국에서 수행되고 있다. 특히, 적외선 카메라(Infrared Camera)를 이용하여 포설 또는 다짐작업 중인 아스팔트포장 표면의 온도분포를 파악하여 품질관리 기준으로 활용하고 있다. 국내에서도 온도분포 파악을 통한 아스팔트포장의 효율적인 다짐관리 방안이 필요하고 이에 대한 연구가 현재 수행되고 있다. In resent years, temperature segregation has been identified as one of the most important concepts concerning segregation. An Infrared Camera is one of the tools that have been recognized to be effective in identifying temperature segregation. Several state of USA have recognized the problem and have enacted Specifications, and/or test procedures to eliminate temperature segregation. The major objective of this study is to investigate effective compaction method of hot mix asphalt during road construction using Infrared Camera.

      • 심부하복벽 천공지 유리피판을 이용한 즉시 유방재건술

        김준형,박지웅,조상헌,어수락,Kim, Jun-Hyung,Park, Ji-Ung,Cho, Sang-Hun,Eo, Su-Rak 대한미세수술학회 2008 Archives of reconstructive microsurgery Vol.17 No.2

        In the past decade, there has been increasing breast reconstructions after mastectomy, and the abdomen has been the gold standard for donor site. TRAM (transverse rectus abdominis myocutaneous), MSTRAM (muscle sparing transverse rectus abdominis myocutaneous), DIEP (deep inferior epigastric artery perforator), SIEA (superficial inferior epigastric artery) flap has been widely used nowadays. Among them, DIEP free flap spares the whole rectus abdominis muscle and anterior rectus sheath resulting in decreased donor site morbidity. Between March of 2006 and February of 2008, six patients had undergone immediate breast reconstructions using DIEP free flap. The mean age of patients was 48.5 years. All patients had unilateral breast reconstructions. We dissected two perforators which were included in the unilateral pedicle. Thoracodorsal artery and its venae comitantes were chosen as recipient vessels. For venous anastomosis, we used the GEM Microvascular Anastomotic Coupler System (Synovis Micro Companies Alliance, Inc., Birmingham, Ala.) in four cases. All flaps were survived completely except one who showed fatty abdomen in old age. She showed repetitive vascular spasm intraoperatively. None of the patients had abdominal hernia, bulge or weakness. We believe that DIEP free flap provides a reliable method for autologous breast reconstruction if the patients are selected appropriately and performed by a skillful surgeon.

        비중격 골절을 동반한 단순 비골 골절의 치료에 있어 비중격 교정술의 중요성: 비강 통기도 검사를 이용한 평가

        김준형,신동우,최태현,손대구,한기환,Kim, Jun-Hyung,Shin, Dong-Woo,Choi, Tae-Hyun,Son, Dae-Gu,Han, Ki-Hwan 대한성형외과학회 2010 Archives of Plastic Surgery Vol.37 No.5

        Purpose: Nasal bone fractures are often classified as minor injury. However, the incidence of posttraumatic nasal deformity remains alarmingly high. It is because of unnoticed septal fracture. This study was conducted to determine the necessity of septoplasty for patients with nasal bone fracture accompanying grade I septal fractures. Methods: Among 105 patients with nasal bone fractures, 52 who had grade I septal fracture were diagnosed based on physical examination and computed tomography. Patients' age ranged from 14 to 65 years (mean 29.25 years), and 35 were male and 17 female. Patients were divided into 2 groups according to surgical treatment methods: patients who underwent closed reduction only (group 1, n=28) and those who underwent simultaneous closed reduction and septoplasty (group 2, n=24). The treatment outcomes were evaluated by comparing changes in nasal airway volume measured by acoustic rhinometry before the surgery, 3 months and 6 months after the surgery according to the timing of surgical repair and surgical treatment methods. Results: Nasal airway volume increased after the surgery by 17.8% in 3 months after the surgery, 25.2% in 6 months in group 1 and by 22.7% in 3 months, 35.8% in 6 months in group 2. The increase in airway volume after the surgery by 26.3% in 3 months after the surgery, 34.2% in 6 months after the surgery in operation within 1 week after trauma and by 12.1% in 3 months, 22.2% in 6 months after the operation later 1 week after trauma. The difference was statistically significant. Three patients in group 1 complained of intermittent nasal obstruction, two of whom showed a decrease in nasal airway volume by acoustic rhinometry. Conclusion: Most patients with nasal bone fractures accompanying grade I septal fractures have been treated with closed reduction in clinical settings. However, the results of this study suggest that septoplasty be performed after a correct diagnosis of septal fracture is made through comprehensive physical examination and computed tomography. Septoplasty is important to obtain more favorable outcomes and reduce complication.

        Tetrameric β를 이용한 고초균 포자에서의 미생물 표면 발현 모체 선별

        김준형,반재구,김병기,Kim, June-Hyung,Pan, Jae-Gu,Kim, Byung-Gee 한국생물공학회 2011 KSBB Journal Vol.26 No.3

        Using tetrameric ${\beta}$-galactosidase as a model protein, anchoring motives were screened in Bacillus subtilis spore display system. Eleven spore coat proteins were selected considering their expression levels and the location in the spore coat layer. After chromosomal single-copy homologous integration in the amyE site of Bacillus subtilis chromosome, cotE and cotG were chosen as possible spore surface anchoring motives with their higher whole cell ${\beta}$-galactosidase activity. PAGE and Wester blot of extracted fraction of outer layer of purified spore, which express CotE-LacZ or CotG-LacZ fusion verified the existence of exact size of fusion protein and its location in outer coat layer of purified spore. ${\beta}$-galactosidase activity of spore with CotE-LacZ or CotG-LacZ fusion reached its highest value around 16~20 h of culture time in terms of whole cell and purified spore. After intensive spore purification with lysozyme treatment and renografin treatment, spore of BJH135, which expresses CotE-LacZ, retained only 1~2% of its whole cell ${\beta}$-galactosidase activity. Whereas spore of BJH136, which has cotG-lacZ cassette in the chromosome, retained 10~15% of its whole cell ${\beta}$-galactosidase activity, proving minor perturbation of CotG-LacZ, when incorporated in the spore coat layer of Bacillus subtilis compared to CotE-LacZ. Usage of Bacillus subtilis WB700, of which 7 proteases are knocked-out and thereby resulting in 99.7% decrease in protease activity of the host, did not prevent the proteolytic degradation of spore surface expressed CotG-LacZ fusion protein.

      • 차세대 RF 트랜시버 기술 동향

        김준형,정재호,권헌국,이광천,Kim, Jun-Hyeong,Jeong, Jae-Ho,Gwon, Heon-Guk,Lee, Gwang-Cheon 한국전자통신연구원 2008 전자통신동향분석 Vol.23 No.3

        차세대 이동통신 서비스나 Beyond 4G 이동통신 서비스의 단말기는 유비쿼터스 정보화 사회의 도래에 발맞춰 기존의 single mode 시스템에서 탈피하여 3G LTE, Mobile WiMAX(WiBro), DMB, IEEE 802.11b/g/n 등의 다중 이동통신 서비스를 지원하는 단말기로 발전하는 추세이다. 또한 고속 데이터 전송을 위한 MIMO 및 스마트 안테나 등의 다중 접속 기능은 다중 밴드/다중 모드/다중 경로 처리 구조의 RF transceiver를 요구하고 있다. 이러한 융합 universal 단말기를 구현하기 위해서는 여러 이동통신 서비스를 지원하는 "Reconfigurability and Convergence" RF transceiver가 필요하지만 현재의 집적 기술로는 0-수 GHz에 할당되어 있는 모든 이동통신 서비스를 지원하는 단말기 구현에 제약사항이 많기 때문에 미국 및 유럽의 국외 연구기관과 기업에서는 2-3개의 선택적인 이동통신 서비스를 지원하는 RF transceiver를 개발하여 세계 시장에서 경쟁 준비를 하고 있다. 본 고에서는 차세대 이동통신 단말기의 RF transceiver 칩 셋 기술과 국내외 개발 동향에 대해 살펴보고자 한다.
