본 연구는 ‘내향성 발톱 교정에 관한 사례 고찰 연구’로서 보다 효과적인 내향성 발톱 교정 방안을 제안하고자 함에 있다. 고찰하여 분석한 결과 배민규, 윤천성(2022)은 내향성 발톱 예방 및 개선⋅교정을 목적으로 활용한 레진 젤(크랄레젤)을 활용한 내향성 발톱 교정 방법이 제품 활용 편리성, 문제점 등에서 다른 연구자들의 연구방법에 따른 문제점 등과 비교했을 때 활용 가치가 있을 것으로 판단했다. 다만 기존 다른 연구자들의 아크릴 스캅춰, Brace System, 실크, 와이어 등 제품들에 비해 교정 효과가 비교적 낮아 김경환(2022) 연구자가 내향성 발톱 교정 효과성 검증을 위해 활용했던 견인기를 함께 활용하기를 제안한다. 내향성 발톱 예방 및 재발 방지를 목적으로 배민규, 윤천성(2022) 연구자가 제안한 크랄레젤 리커버 1회 적용을 제안하고, 내향성 발톱 개선 및 교정을 목적으로 김경환(2022) 연구자가 활용한 견인기를 활용하여 발톱을 펴준 후, 배민규, 윤천성(2022) 연구자가 제안한 크랄레젤 리커버를 목적에 맞게 2~5회 적용하여 활용하기를 제안한다. 본 연구 자료가 내향성 발톱 질환으로부터 건강한 삶을 영위하기 위한 자료로 활용될 수 있기를 기대해 본다. As “a case study on the correction of ingrowing nail”, this study aims to suggest more effective measures for the correction of ingrowing nail. In the results of considering and analyzing it, the correction of ingrowing nail using the Resin Gel(Kralle Gel) which was used by researchers Min-Gyu Bae & Chun-Sung Youn(2022) for the purpose of preventing, improving, and correcting the ingrowing nail, seemed to be more useful than other methods used by other researchers in the aspect of convenience of product use and problem. However, compared to the products like Acrylic Sculpture, Brace System, Silk, and Wire used by other researchers, the effect on correction was relatively lower, so it is proposed to be used together with the Retractor that was used by Kyeong-Hwan Kim(2022) for verifying the effectiveness on the correction of ingrowing nail. This study suggests applying Kralle Gel Recover one time suggested by Min-Gyu Bae & Chun-Sung Youn(2002) for the purpose of prevention & recurrence prevention of ingrowing nail, unbending the nail by using the Retractor used by a researcher Kyeong-Hwan Kim(2022) for the purpose of improving/correcting the ingrowing nail, and then applying Kralle Gel Recover 2-5 times suitable for the purpose, suggested by researchers Min-Gyu Bae & Chun-Sung Youn(2022). The results of this study are expected to be utilized as the data for enjoying a healthy life from ingrowing nail disease.

성상진,김인태,국윤아,전윤식,김성훈,모성서 대한치과교정학회 2009 대한치과교정학회지 Vol.39 No.5

효과적인 교정치료계획의 수립을 위하여 치열군의 저항중심의 위치에 대한 평가는 필수적이다. 이번 연구의 목적은 상악 치열군(4전치, 6전치, 14치아)에서 치조골 손실에 따른 저항중심의 위치변화를 조사해보고자 하였다. 상악 전치열 14개 치아와 치주인대 및 0 mm, 2 mm, 4 mm 손실된 치조골의 3차원 유한요소 모델을 제작하였고 각 치아군(4전치, 6전치, 14치아)별로 치관부를 협측, 설측호선 및 splint wire로 고정하여 치아군 모델을 제작한 후 상악 중절치의 절단연 중점에서 연장된 splint wire에 4전치와 6전치군에는 200 g, 14치아군에는 400 g의 후방 견인력과 압하력을 적용하여 저항중심의 수직적, 수평적 위치를 분석하였다. 4전치군에서 저항중심의 수직 위치는 치조골 0 mm, 2 mm, 4 mm 손실에 따라 중절치의 절단연에서 치근방향 13.5 mm, 14.5 mm, 15 mm, 수평 위치는 후방 12 mm, 12 mm, 12.5 mm, 6전치군에서는 치근방향 13.5 mm, 14.5 mm, 15.5 mm, 후방 14 mm, 14 mm, 14.5 mm, 14치아군에서는 치근방향 11 mm, 13 mm, 14.5 mm, 후방 26.5 mm, 27 mm, 25.5 mm에 위치하였다. 모든 치아군에서 저항중심은 치조골 손실에 따라 치근첨 방향으로 이동하였으나, 치조정과의 거리는 가까워졌고, 4전치군과 6전치군에서 저항중심은 치조골 손실에 따라 후방으로 이동하였으나, 14치아군에서는 치조골 2 mm 손실 시에는 후방으로 이동하였으나, 4 mm 손실 시에는 전방으로 이동하였다. Objective: The aim of this study was to investigate the changes in the center of resistance of the maxillary teeth in relation to alveolar bone loss. Methods: A finite element model, which included the upper dentition and periodontal ligament, was designed according to the amount of bone loss (0 mm, 2 mm, 4 mm). The teeth in each group were fixed with buccal and lingual arch wires and splint wires. Retraction and intrusion forces of 200 g for 4 and 6 anterior teeth groups and 400 g for the full dentition group were applied. Results: The centers of resistance were at 13.5 mm, 14.5 mm, 15 mm apical and 12 mm, 12 mm, 12.5 mm posterior in the 4 incisor group; 13.5 mm, 14.5 mm, 15 mm apical and 14 mm, 14 mm, 14.5 mm posterior in the 6 anterior teeth group; and 11 mm, 13 mm, 14.5 mm apical and 26.5 mm, 27 mm, 25.5 mm posterior in the full dentition group respectively according to 0 mm, 2 mm, 4 mm bone loss. Conclusions: The center of resistance shifted apically and posteriorly as alveolar bone loss increased in 4 and 6 anterior teeth groups. However, in the full dentition group, the center of resistance shifted apically and anteriorly in the 4 mm bone loss model.

「気持ち」「気分」「機嫌」의 비교연구 : いい·わるい와 결합하는 경우를 중심으로

全成龍 청주대학교 인문과학연구소 2018 人文科學論集 Vol.57 No.-

日本語における「気持ち」「気分」「機嫌」という三つの言葉 は、韓国語において、一般的に「기분」という、一つの言葉に翻 訳される。言い換えれば、韓国語における「기분」という言葉 は、日本語において、「気持ち」「気分」「機嫌」という三つの 言葉に翻訳されるわけである。それでは、日本語において、「気持ち」「気分」「機嫌」とい う三つの言葉の違いはないのであろうか。このことを出発点とし て、ここで、これらの言葉が「いい」「悪い」という形容詞と組 み合わされる場合に限定して、この三つの言葉が表す意味の違い を明らかにしたのである。すなわち、日本語における「気持ち」という言葉は、視覚·聴覚· 觸覺などの感覚を表すものであり、「気分」という言葉は、肉体 的な苦痛や爽快を表すものであり、「機嫌」という言葉は、精神· 心理的なことを表すものである。

온도 변화가 교정용 니켈-티타늄 호선의 하중값에 미치는 영향

천경애,임성훈,김광원 대한치과교정학회 2007 대한치과교정학회지 Vol.37 No.6

초탄성 니켈-티타늄 호선의 하중값은 온도 변화에 따라 변화함이 보고된 바 있다. 따라서 본 연구에서는 온도가 변화함에 따라 니켈-티타늄 합금 호선의 하중값이 어떻게 변화하는지 알아보고자 하였다. 37℃ 항온 상태에서 0.016" x 0.022" 니켈-티타늄 호선을 3.1mm까지 변위시키는 3점 굴곡 실험을 시행하여 하중 시와 탈하중 시의 1.5mm 변위지점의 하중값을 측정하고 이 지점에서 구강내 온도 변화를 고려한 온도 변화 실험을 시행하였다. 20℃ 저온수 또는 50℃ 고온수를 호선에 흘려보냄으로써 온도 변화를 주었다. 저온 실험은 저온수로 온도 변화를 주고 37℃ 항온 온도로 회복된 후에 다시 저온수를 흐르게 하는 방법으로 10회 시행하였고 고온 실험도 동일한 방법으로 시행하였다. 그 결과 하중 시 1.5mm 변위지점의 하중값은 저온 실험 및 고온 실험 후 37℃로 회복된 후에도 모두 감소된 값을 유지하였다. 반대로 실제로 치아에 가해지는 교정력으로 생각되는 탈하중 시 1.5mm 변위 지점의 하중값은 저온 실험 및 고온 실험 후 온도가 37℃로 회복되어도 모두 증가된 값을 유지하였다. 이상의 결과를 종합해 볼 때 온도변화를 거친 후 초탄성 니켈-티타늄 합금 호선의 하중 시 힘은 감소하였고 탈하중 시 힘은 증가되므로, 임상에서 니켈-티타늄 호선을 적용 시에는 37℃에서의 하중-변위 곡선에서 나타나는 힘에 비해 더 작은 하중 시 힘과 더 큰 탈하중 시 힘이 적용될 수 있음에 유의하여야 한다. Objective: The purpose of this study was to evaluate the influence of intraoral temperature changes on the orthodontic force level of a superelastic nickel-titanium alloy wire. Methods: Nickel-titanium archwires of 0.016" x 0.022" thickness were tested with a three point bending test setup, and temperature changes were applied. The force level changes according to temperature changes were measured at a 1.5mm deflection during the loading phase and a 1.5mm deflection during the unloading phase from a deflection to 3.1mm. Ten cycles of thermal cycling from baseline (37℃) to cold (20℃) or hot (50℃) temperature were applied. Results: After thermal cycling, the force level during the loading phase decreased and the force level during the unloading phase increased even after the temperature was changed to the initial 37℃. Conclusions: The results suggest that the orthodontic force level can not return to the initial force level after temperature changes. When applying superelastic nickel-titanium archwires, we must consider that a lighter force than the loading force and a heavier force than the unloading force will be applied after intraoral temperature changes caused by eating and drinking.

전정현,정성애,김성은,이종수,남승현,신정은,문혜성,김승철,유권 梨花女子大學校 醫科大學 醫科學硏究所 2003 EMJ (Ewha medical journal) Vol.26 No.1

연구목적 : 2형 Lynch 증후군에 대한 관심이 높아지면서 부인과 종양 환자에게 대장암과 대상 선종의 검사 필요성이 언급되어지고 있다. 본 연구에서는 본원의 부인과 종양 환자에서 병기 결정을 위해 시행되어지는 S상 결장경 검사에서 발견되는 대상 선종의 특징을 알아보고자 하였다. 방법 : 1993년 9월부터 2001년 3월까지 본원에서 부인과 종양을 진단받고 대장 증상 없이 병기 결정을 위해 S상 결장경검사를 시행한 187명을 대상으로 하였고(자궁경부암 139명, 난소암 35명, 자궁 내막암 13명) 정상대조군으로는 대장 증상 없이 건강 검진 목적으로 대장경 검사를 시행한 58명을 대상으로 하였다. 결과 : 부인과 종양 환자 187명 중 21명에서 대장 선종이 발견되었고(11.2%) 다발성 선종이 있어 모두 26예의 선종이 관찰되었다. 정상 대조군 58명에서는 3명에서 선종이 발견되었고(5.2%) 다발성 선종은 없었다. 부인과 종양 중 자궁 내막암 환자군에서 선종의 빈도는 38.5%로 정상 대조군에 비해 통계학적으로 유의하게 많았다. 진행성 선종의 빈도도 자궁 경부암 환자 12.5%, 난소암 환자 25.5%, 정상 대조군 33.3%에 비해 자궁 내막암 환자 83.5%로 유의하게 많았다. 부인과 종양의 선종 위치는 직장이 23.1%, S상결장이 76.9%였다. 결론 : 부인과 종양 환자의 대장 선종 빈도는 정상 대조군에 비해 많은 경향을 보였으나 통계학적 의의는 없었다. 그러나 자궁 내막암 환자군에서는 다른 부인과 종양 환자나 정상 대조군에 비해 유의하게 많은 선종과 진행성 선종의 빈도를 부였다. 따라서 부인과 종양 환자에게 대장경 검사를 통한 대장 선종 유무 검사가 필요하리라 생각된다. Objectives : In Lynch syndrome Ⅱ, colon cancer was associated with endometrial and ovarian cancer. The aim of this study was an evaluation for the clinicopathologic characteristics of rectosigmoid adenomas on preoperative sigmoidoscopy in gynecologic cancer patients. Methods : A total 187 gynecologic cancer patients(139 cervical, 35 ovarian, 13 endometrial cancer) and 58 normal controls were reviewed sigmoidscopic finding and pathologic reports retrospectively from September 1993 to March 2001. Results : The mean age of gynecologic cancer patients was 54(38-82) year-old and normal controls was 50(20-68) year-old. Total 26 adenomas were in 21 patients(11.2%) and 3 adenomas were in 3 normal controls(5.2%). The incidence of adenomas was 9.4% in cervical cancer, 8.6% in ovarian cancer and 38.5% in endometrial cancer. Multiple adenomas were in 5 gynecologic cancer patients and 0 normal controls. The incidence of advanced adenoma was 12.5% in cervical cancer, 25.5% in ovarian cancer, 83.5% in endometrial cancer and 33.3% in normal controls. The location of adenoma was 23.1% in rectum and 76.9% in sigmoid colon. Conclusion : The incidence of adenomas and multiple adenomas were higher in gynecologic cancer patients than normal controls but not significantly. The incidence of advanced adenoma and adenomas were significantly higher in endometrial cancer than normal controls. Colonoscopic evaluation of whole colon will be recommanded in gynecologic cancer than sigmoidoscopy.

흰쥐 삼차신경 척수감각핵 미측소핵 세포의 흥분성 시냅스 전도에 대한 nociceptin의 효과

천상우,민승기 大韓顎顔面成形再建外科學會 2003 Maxillofacial Plastic Reconstructive Surgery Vol.25 No.3

The caudal subnuleus of the spinal trigeminal nucleus(medullary dorsal horn;MDH)is implicated in the processing of nociceptive information in the orofacial region. In the present study, whole cell patch clamp recordings were carried out on MDH neurons in brainstem slic of neonatal rats to investigate the characteristics of spontaneous excitatory postsynaptic currents(sEPSCs) and the roles of nocieptin/orphanin FQ on excitatory synaptic transmission. In the presence of atrychnine(1uM) and bicuculline(20uM), spontaneous inward currents at -70㎷ were observed. the baseline frequency, amplitude and decay time constant of sEPSCs were 2.0±0.5㎐,23.0±1.8㎀, 3.8±0.2㎳, repectively. sEPSCs were mediated by non-NMDA and NMDA receptors. The specific AMPA receptor antagonist GYKI-52466(50uM)completely blocked the non-NMDA mediated sEPSCs, indicating that they are mediated by an AMPA-preferring receptor. Perfusion of the opioid orphan receptor(ORL₁)agonist nociceptin(3uM)reduced the frequency of sEPSCs and miniature EPSCs(mEPSCs). The effects of nociceptin were blocked by the selective ORL₁receptor antagonist〔Nphe'〕nociceptin(1-13)NH_2(3uM)and were not affected by the non-specific opioid receptor antagonist naloxone(10uM). To investigate the specificity of this synaptic inhibition, we selectively astivated the nociceptive C fibers with capsaicin, which induced a strong increase in the frequency of sEPSCs. In the presence of nociceptin, the response to capsaicin was diminished. In concilsion, these results suggest that nociceptin inhibits excitatory synaptic transmission in the MDH by acting on presynaptic ORL₁receptors.

<여와전>과 <봉신연의> 대비의 소설사적 의미

전성운 釜山大學校 韓國民族文化硏究所 2004 한국민족문화 Vol.24 No.-

The aim of this thesis is comparative study between <Yeowachon> and <FengShenYanYi>. It is expected that the comparative study is to clear the homogeneity and heterogeneity of theme and materials in these works. <Yeowachon> is very important work to understand the history of novels specially before the early 18th century. And <FengShenYanYi> is a representative historical novel with the character of mythical heroes. These works have lots of same sides the title, characters, plots and the method of descriptions. And more, these works have the similar theme which establishes order in the world of chaos. These facts mean that these works are published at the similar generation of novel history. Even though there are lots of similar sides between them, we can't conclude that <Yeswachon> are created in similitude of <FengShenYanYi>. We can't sure the influences of <FengShenYanYi>. And more important, there are many different sides between them. For examples, <Yeswachon> not only has characteristics of historical novels but the characteristic of dream novels. And the ground of ideology, the aesthetic sense and characters are different from those of <FengShenYanYi>. Like these, similar and different sides between them are originated from the developments of novel history of each countries. The novel histories of each country developed very similar, and also they have different literary hereditaments. So obviously, they have no relations but have lots of similar sides.

성춘자,박재국 남서울대학교 2005 남서울대학교 논문집 Vol.11 No.2

The use of GIS function in appraisal value of land generates value appraisal factor and spatial analysis. With it, we can expect the following benefits during the appraisal value of land task. First, through the GIS information collection, generation, and transformation function, it allows us to acquire the various appraisal factor for appraisal value of land and minimize the field data collection. Second, it allows us to explore the plural utilization of appraisal value of land through the evaluation of land location and spatial relation. Even the GIS spatial analysis application is an early phase among the appraisal task, it is expected that it will contribute greatly to the land appraisal task information activities and effectiveness acquisition

ATM망에서 ABR서비스를 위한 효율적인 전송률 할당 알고리즘에 관한 연구

천재호,윤상호,김명균,허정석 울산대학교 1999 공학연구논문집 Vol.30 No.2

ATM망에서 ABR 서비스는 CBR, VBR에 할당된 대역폭을 제외한 나머지를 이용해서 데이터를 전송한다. 오디오 또는 비디오 데이터와 같이 실시간 전송이 필요한 서비스들을 전송지연이 제한되는 CBR이나 VBR 트래픽을 이용하여 제공할 수 있지만, 이런 경우에는 전송 대역폭을 효율적으로 사용하지 못하는 단점이 있다. 본 논문에서는 실시간 데이터를 ABR 서비스를 이용하여 효율적으로 전송하기 위한 ABR 대역폭 할당 알고리즘을 제안한다. 제안된 알고리즘은 MCR을 보장하며, MCR에 비례해 전송률을 할당한다. 그리고 접속의 상태를 만족(satisfied)상태와 불만족(bottlenecked)상태로 구분하고, 만족 상태인 접속이 사용하지 않는 대역폭을 불만족 상태인 접속이 사용할 수 있도록 하여 대역폭 활용도를 높인다. 또한 제안된 알고리즘은 큐 제어 함수를 사용해서 큐 길이를 일정한 범위로 유지함으로써 셀의 전송지연을 일정하게 한다. 본 논문에서는 시뮬레이션을 통해 제안된 알고리즘의 성능을 분석하고, 기존에 제안된 ATM 포럼[1]및 Kalampoukas 알고리즘[2]과 비교를 하였다. On ATM networks, ABR services are provided using the remained bandwidth after allocating CBR and VBR traffic. Realtime services such as transmitting audio or video data may be provided using CBR and VBR which have a constrained transmission delay, but in those cases, the communications bandwidth may be wasted. This paper proposes an efficient ABR rate allocation algorithm to transfer real-time data using ABR service. The proposing algorithm guarantees MCR and allocates bandwidth to each connection proportional to its MCR. The proposing algorithm divides the connections in two groups, a satisfied state group and a bottlenecked state group, and enhances bandwidth utilization by allowing the remained bandwidth after allocating to the connections in the satisfied state to the connections in the bottlenecked state. The proposing algorithm uses the queue control function to keep the queue length within some boundary, which makes the transmission delay constant. We simulate and compare the performance of the proposing algorithm with that of the algorithms proposed by ATM Forum[1] and Kalampoukas[2].

The HBV DNA Amounts in Serum Have No relationship with ALT level and Hetergeneous Population Coexits in Chronic Hepatitis B Virus Infection

Yoon-Keun Chun¹,Joohun Ha□Hong-Jung Woo□, Soo Myung Oh□,Sung Soo Kim□ ¹Department of Molecular Biology, College of Medicine,²Department of Surgery, college of Medicine,³Department of Internal Medicine, College of Oriental Medicine,and ⁴East-Weat Medical Reserch Institute,Kyung Hee University, Seoul, Korea. The HBV DNA Amounts in Serum Have No relationship with ALT level and Hetergeneous Population Coexits in Chronic Hepatitis B Virus Infection. Proceedings of International Symposium on East-West Medicine, Seoul. 212-230, 1999. -Hepatitis B is caused by hepadnavirus. Hepatitis B virus replicates through 3.5kb pregenomic RNA intermediate which is regulated by core promoter. Pathogenesis of hepatitis B virus has been bilieved the result of host immune response. But recently many studies have reported that high level of viral replication caused by mutation in core promoter might result in severs hepatitis. But these studies were performed in vitro, not in vivo. So there is yet debate about which factor, viral of host factor, is more important in pathogenesis of hepatitis B virus. So we measured real viral replication level in 204 chronic hepatitis B patients by quantifying HBV DNA from sera by our novel PCR-based more sensitive method, and compared these results with ALT level measured from same sera, which indicates liver cell damage. Surprisingly there are no significant correlation between HBV DNA quantity and ALT level. Then we cloned core promoter region. In SSCP, we found that many viral mutants coexist in one patient. Base on SSCP result, we chose main viral core promoter type in each patients, which is thought to determine overall viral replication level in this patient. Main type of core promoter region of each 41 patients were directly sequenced. And with these we measured promoter activity by luciferase assay system and compared promoter activity with on another. We found tha there were some differences in promoter activity according to core promoter sequences. And we constructed replication-competent viral constructs with core promoter from 41 patients and Transfected these into HepG2 cell and measured HBV DNA by southern blot. There were also differences in HBV DNA quantity according to core promoter sequences. On these all results we investigated correlation between the effect of HBV core promoter on viral replication in vitro and HBN DNA quantity, ALT level from sera of each patients. We found there is no significant correlation among them. As a result, we concluded that in determining severity chronic hepatitis B patients, host factors of each patient is more important rather than replicative activity of virus itself.
