Carcinoma of the mouth accounts for approximately 5% of all carcinomas occurring in man. Carcinoma of the oral cavity develops as a result of invasion of malignant epithelial cells through the normally intact basal cell layer into subcutaneous and submucosal tissuse. The sofe palate and uvula may be involved in oral cancer but are not common sites. Early lesions of soft palate carcinoma appear as red, white, or mixed changes in the mucosa. The earliest symptom is mild sore throat. Advanced lesions interfer with swallowing and may cause a voice change. Although surgical method of soft palate carcinoma is successful, prognosis is relatively poor to swallowing and speech problem. Occasionally marginal recurrence may be developed. This article reports a case of squamous cell carcinoma occurred unusually in the soft palate and uvula. The case was treated with neoadjuvant chemotherapy, local radicalexcision and postoperative irradiation. Patient was followed up for 2 years. There was no tumor recurrence. The overall result including function was satisfactory.

유병민,박수홍,강문숙,박철수,정경훈 교육혁신학술위원회 2011 교육혁신연구 Vol.21 No.1

본 연구는 예비보육교사가 보육실습이라는 과정에서 프로젝트 접근법에 대한 관심은 어떠하며, 관심변화 여부를 사례중심으로 살펴보는 것을 목적으로 하였다. 이를 위하여 예비보육교사를 대상으로 보육실습 사전과 사후검사를 실시하였으며, 자세하고 구체적인 사실과 연구의 질적인 부분을 찾아보고자 인터뷰하였다. 그 결과, 첫째, 프로젝트에 대한 예비보육교사들의 관심은 전반적으로 무관심으로 나타났다. 둘째, 사전․사후검사 결과, 프로젝트 접근법에 대한 관심수준의 변화가 있었던 사례에서는 관심변화의 패턴도 다양하게 나타났으며, 관심변화가 크게 없었던 사례에서는 개인, 정보관심이 높게 나타났다. 이러한 결과는 프로젝트에 대한 예비보육교사의 관심수준은 보육환경, 보육과정, 실습지도 교사, 예비보육교사의 지각력, 프로젝트에 대한 사전지식이나 교육정도에 따라 다양하게 변할 수 있음을 알게 되었다. The purpose of this study is to analyze the case in which we can identify how the SoC of prospective child care teachers about the project approach changes and why these change appears during the child care practice when we assumpt that for prospective child care teachers to implement the project approach is that they participate in change during child care practice. In Case K, the SoC of the prospective child care teacher moves from Stage 0 awareness to Stage 2, Stage 3, Stage 4, and In Case M, the SoC moves from Stage 0 to Stage 1. In Case P, the SoC moves from Stage 1 to Stage 2, Stage 3, and in Case S, the SoC isn't changed. Above this, we identify the SoC of prospective child care teachers. Case K, M, and P changes SoC after child care practice, but Case S doesn't change. the reason why there is a difference is the mindset of prospective child care teachers. Anyone who wants to accomplish specific purposes can deal with diverse changes with flexibility, but others can easily have an effect on the changes. We suggest that instructor in organization for prospective child care teachers’ education need to have a class for prospective child care teachers to put theory into practice, give direct facilitation and intervention in the field to prospective child care teachers, make a learning environment for prospective child care teachers to make good use of teaching materials and instrument, develop guidebook for project approach and give support to prospective child care teachers.

Synthesis of Monolayer Graphene Having a Negligible Amount of Wrinkles by Stress Relaxation

Mun, Jeong Hun,Cho, Byung Jin American Chemical Society 2013 NANO LETTERS Vol.13 No.6

<P>For the chemical vapor deposition (CVD) of graphene, the grain growth of the catalyst metal and thereby surface roughening are unavoidable during the high temperature annealing for the graphene synthesis. Considering that nanoscale wrinkles and poor uniformity of synthesized graphene originate from the roughened metal surface, improving surface flatness of metal thin films is one of the key factors to synthesize high quality graphene. Here, we introduce a new method for graphene synthesis for fewer wrinkle formation on a catalyst metal. The method utilizes a reduced graphene oxide (rGO) interfacial layer between the metal film and the wafer substrate. The rGO interlayer releases the residual stress of the metal thin film and thereby suppresses stress-induced metal grain growth. This technique makes it possible to use much thinner nickel films, leading to a dramatic suppression of RMS roughness (∼3 nm) of the metal surface even after high temperature annealing. It also endows excellent control of the graphene thickness due to the reduced amount of total carbon in the thin nickel film. The synthesized graphene layer having negligible amount of wrinkles exhibits excellent thickness uniformity (91% coverage of monolayer) and very high carrier mobility of ∼15 000 cm<SUP>2</SUP>/V·s.</P><P><B>Graphic Abstract</B> <IMG SRC='http://pubs.acs.org/appl/literatum/publisher/achs/journals/content/nalefd/2013/nalefd.2013.13.issue-6/nl4005578/production/images/medium/nl-2013-005578_0006.gif'></P><P><A href='http://pubs.acs.org/doi/suppl/10.1021/nl4005578'>ACS Electronic Supporting Info</A></P>

Wall Charges and Transition Voltage of Microplasma Modes in Plasma Devices With an Auxiliary Electrode

Mun, Jeong Hun,Kim, Seung Hun,Choi, Kyung Cheol IEEE 2008 IEEE transactions on electron devices Vol.55 No.11

<P> In this paper, the characteristics of microdischarge phenomena in a plasma device with an auxiliary electrode located on the center of the coplanar gap were investigated. The microdischarge showed three discharge modes in accordance with the auxiliary pulse voltages, and its luminous efficacy was improved when it operated in the efficient mode. To understand the mechanisms of that improvement of efficiency, a wall-charge measurement system was proposed and applied to measure the wall-charge behavior, which is a key for the diagnosis of discharge characteristics. For the efficient mode, measurement of wall-charge behavior indicated the presence of the three high efficiency factors, namely, long-gap discharge, current reduction, and priming effect. For the inefficient mode, however, the measured wall-charge behavior indicated that strong short-gap discharges were generated between sustain and auxiliary electrodes, and then, the high efficient factors were not observed. Additionally, in order to operate the device in the efficient mode, the tendency of the mode transition was investigated in terms of panel specifications, such as barrier rib height and coplanar gap. The results indicate that the transition voltage between the efficient and inefficient modes increased when the barrier rib height increased, and it showed the tendency resembling the Paschen curve with various coplanar gaps. </P>

Optical reflectance measurement of large-scale graphene layers synthesized on nickel thin film by carbon segregation

Mun, Jeong Hun,Hwang, Chanyong,Lim, Sung Kyu,Cho, Byung Jin Elsevier 2010 Carbon Vol.48 No.2

<P><B>Abstract</B></P><P>The change of surface roughness during graphene synthesis on evaporated Ni thin films was monitored. It was found that Ni is highly agglomerated during high temperature annealing but the surface roughness is made smoother by the coverage of graphene. It is demonstrated that diffuse reflectance is a fast and convenient technique for evaluating surface roughness over a large area of graphene on a metal film, and specular reflectance is a good indicator of the coverage of graphene on the metal film.</P>

Mun, Ji-Hun,Kim, Dong-Hyun,Ryu, Kyeong-Sik,Park, Chun-Kun,Kim, Moon-Chan The Korean Neurosurgical Society 2005 Journal of Korean neurosurgical society Vol.38 No.3

Objective : Our aim is to evaluate the early changes of biologic markers such as white blood cell[WBC] count, erythrocyte sedimentation rate[ESR] and C-reactive protein[CRP] in early diagnosis of postoperative infection and to differentiate infection from inflammatory reaction in lumbar spine surgery. Methods : We reviewed 330patients who had undergone spinal operations between May 1999 and October 2001. For this study, the patients were classified into two groups, which include a group that underwent spinal decompressive surgery without instrumentation[SD], and the other group that underwent fusion surgery with spinal instrumentation[SI]. And each group was also subdivided into two groups respectively, one with infection and the other without infection. We retrospectively analyzed the WBC count, ESR and CRP preoperatively and postoperatively, according to their operation type and postoperative infection history. Results : Inflammatory indices were physiologically affected by instrumentation itself. But ESR and CRP elevations were more prolonged and sustained under infection. In SD patients without infection, ESR and CRP were stabilized 5 days after surgery. In SI patients without infection, CRP was stabilized about 7days after surgery, but ESR showed sustained and variously elevated. In both SD and SI groups, the stabilization of CRP was the most reliable behavior of surgery without infection. Conclusion : C-reactive protein is most sensitive parameter for postoperative spine infection. The knowledge of the inflammatory indices and their relatively uniform patterns with or without infection offers surgeons the ability to infer the state of surgical wound.
