과립상 세포종은 Schwann 세포 기원으로 생각되며 인체에 비교적 드물게 발생한다. 과립상 세포종은 전신 어느 곳에서나 발견될 수 있으나 주로 혀, 구강, 피부 혹은 유방 등에서 호발하며 드물게 위장관에서 발견된다. 위장관에서는 식도에서 가장 호발하며 다음으로 위, 대장 순이다. 과립상 세포종은 대부분, 특히 위장관에서는 양성이며 소수의 악성 병변이 보고되었다. 이러한 이유와 함께 수술 전의 진단이 어렵기 때문에 과립상 세포종에 대한 근본적인 치료는 현재까지 외과적 절제술이다. 최근에 시도되는 치료방법들로는 내시경적 레이저 치료, 용종절제술, 내시경적 점막 절제술 등이 있다. 저자들은 상부 소화관 내시경검사를 시행하여 식도 과립상 세포종을 진단하고 내시경적 점막 절제술을 시행하여 합병증 없이 퇴원하여 현재 재발없이 경과 관찰중인 1례를 경험하였기에 보고하는 바이다. Granular cell tumors, which occur infrequently, are probably of Schwann cell origin. They can occur almost anywhere in the body but usually affect the tongue, oral cavity, skin, or breasts and are rarely found in the gastrointestinal tracts. The esophagus is the most frequent gastrointestinal site, followed by the stomach and the colon. Granular cell tumors are generally benign, especially in the gastrointestinal tract, some malignant lesions have been reported. For this reason, and also because preoperative diagnosis is difficult, the standard treatment for granular cell tumor has until now been surgical excision. In recent years, other therapeutic methods is endoscopic laser therapy (ELT), polypectiomy, endoscopic mucosal resection (EMR). We report a case of esophageal granular cell tumor which was diagnosed by an endoscopy and managed using an endoscopic mucosal resection without complication.

물질주의가 과시소비, 충동구매와 삶의 만족 및 부정적 감정에 미치는 영향

[연구목적] 물질주의의 부정적인 영향에 대한 선행연구들은 이루어져 왔지만, 물질주의가 과시소비 및 충동구매에 영향을 미치고 이러한 비합리적인 소비가 삶의 만족 및 부정적 감정에 미치는 전체 변수들 간의 연구는 전무했기에 본 연구에서 이러한 관계들이 동시에 미치는 영향을 살펴보고자 한다. [연구방법] 본 연구는 자료 분석을 위해 신뢰도분석, 탐색적 요인분석, 확인적 요인분석을 실시한 후 측정모델의 적합도를 평가하였고, 이를 바탕으로 측정모형과 구조모델을 동시에 측정하는 구조방정식 검증을 실시하였다. [연구결과] 본 연구를 통한 결과는 다음과 같다. 물질주의가 높을수록 과시소비와 충동구매를 더 하는 것으로 나타났다. 그리고 과시소비 성향이 높을수록 삶의 만족도는 낮아지며, 부정적 감정은 높았다. 마지막으로 충동구매 성향이 높을수록 부정적 감정은 높았지만, 삶의 만족도에는 영향을 미치지 않는 것으로 나타났다. [연구의 시사점] 본 연구의 결과를 토대로 청소년들의 올바른 가치관과 소비 형태를 정립할 수 있는 교육 자료로 활용할 수 있을 것이라 본다. 그리고 물질주의를 통한 올바르지 못한 구매들이 부정적인 감정을 높이고 삶의 만족을 떨어뜨릴 수 있음을 공익광고를 통해 건전한 인식 전환을 시도해 볼 수 있을 것이며, 구매 후에 느낄 수 있는 부정적 감정들에 대해서는 과시를 통한 우월감, 만족감으로 대신하거나, 실용적인 측면들을 내세워 소비에 대한 정당성을 확보하여 부정적 감정들을 완화 시킬 수 있을 것으로 본다. [Purpose] Previous studies on the negative effects of materialism have been carried out, there has been no study of materialism’s effects on conspicuous consumption and impulse buying nor the study of entire variables between the effects of irrational consumption and satisfaction with life and negative emotions. In this context, this study examines the simultaneous effects of the relationships. [Methodology] This study evaluated the measuring model’s fitness after performing a reliability analysis, an exploratory factor analysis, and a confirmatory factor analysis. Based on this, the verification of the structural equation model simultaneously measuring the measuring model and the structural model was performed. [Findings] The results of this study are as follows: As materialism was higher, conspicuous consumption and impulse buying were higher. As conspicuous consumption was higher, satisfaction with life became lower but negative emotions were higher. Lastly, as the impulse buying disposition was higher, negative emotions were higher, but it did not affect satisfaction with life. [Implications] The result of this study can be used for educational data to establish adolescents’ proper values and behavioral patterns. A sound awareness shift that improper buying can elevate negative emotions and lower satisfaction with life can be attempted through public service advertisement. Negative emotions can be eased by securing legitimacy on consumption by replacing negative emotions with sense of superiority and satisfaction or by presenting the practical aspect.

The purpose of this study is to identify the problems of the voluntary activities and to develop strategies encoraging more voluntary activities in the Gyeongsang National Unversity. For this purpose, a survey interview for the students was conducted to identify their characteristics, duration and continuation of action, motivation, and attitudes. The survey found that volunteers are not reliable work sources yet, because only 37.9 percent of students were experienced in voluntary action, and their participations are not on the regular bases and do not last long enough. This finding suggests that if systematic supporting body is established in the university, many students may better participate in the voluntary activities Based on these findings, some policy recommendations are suggested as follows; 1)The volunteer support regulation should be legislated as soon as possible. The regulation should include such regulations as establishment of volunteer center, curriculum, and supporting systems such as insurance, incentives, and approval of career. 2) The centralized supporting organization, so-called "Gyeongsang Voluntary Center" should be established. In order to establish effective center that provide organized, coordinated and well-managed service efforts, a broad and sustainable foundation of support is necessary. Most importantly, it requires the building of genuine relationship across the student body, academic discipines, community boundaries, administrative departments. 3) Voluntary coordinators should be trained so that they can play a variety of professional roles in managing volunteer programs. 4) Various voluntary action programmes should be developed. 5) In order to increase the efficiency in voluntary activities, database and computerization should be developed. 7) Against accidents during voluntary activities, a social insurance system should

두경부 종양세포주에 대한 Mithramycin A의 세포자멸사 유도성 및Cisplatin 항암작용 증가효과

이강대,손성환,박종욱,김영록,이봉주,김주연 고신대학교의과대학 2008 고신대학교 의과대학 학술지 Vol.23 No.1

Background and Objectives : Cisplatin (CP) is a major chemotherapeutic agent for head and neck cancer. However, cancer cells can get drug resistance through recovering the DNA damage by CP. Mithramycin A (MA) can inhibit gene expression of multidrug resistance gene 1, c-myc or h-ras. The goal of this study is to evaluate the therapeutic effect of MA alone and combination of MA and CP on head and neck cancer cell lines. Materials and Methods : Two head and neck cancer cell lines (AMC-HN4, AMC-HN7) were treated with MA. The cellular proliferation, apoptosis and protein expression were measured with XTT assay, FACS analysis, and western blotting, respectively after MA treatment in cell lines. In order to know the combination effect of MA with CP, the cancer cell lines were treated with MA, CP, and MA/CP combination, and cellular proliferation, apoptosis and expression of apoptosis-associated proteins were measured. Results : MA inhibited the proliferation of head and neck cancer cells and induce dapoptosis. Increase of caspase activation, PLC-?1 fragmentation and percent apoptosis by MA treatment was blocked by z-VAD-fms, but not blocked by N-Acetyl Cystein. Combination of MA and CP significantly inhibited cancer cell growth and increased apoptosis compared to MA and CP alone, and it also suppressed the expression of anti-apoptotic proteins such as XIAP and Mcl-1. Conclusions : The present study suggests that MA alone andMA/CP combination chemotherapy could be a potential regiment for the control of the head and neck cancer.

At the area of Yuhak, Cheonsaeng and Seongam mountains in Kyeongbuk, we studied the vegetation patterns with 75 plots on the base of Braun-Blanquet methods from March to October 2002. For the analysis of community patterns with 75 plots we used interspecies Affinity analysis method, DECORANA and TWINSPAN. The investigated area was divided into 17 communities with 177 species, and 20∼100% of treelayer, 10∼95% of shrublayer and 20∼100% of herblayer. By toe method of affinity analysis, it showed a big community with 86 species, but divided into 6 small groups by ordination and classification methods. Although it appeared as one group by the affinity test, the area divided into two groups by classification method at second level with eigenvalue of 0.320 and 0.430. It shows that the area of Yuhak, Cheonsaeng and Seongam mountains have own properties and in the process of succession.

박강일,김병섭,이성욱,김현수,이세종,곽동주 경성대학교 공학기술연구소 2003 공학기술연구지 Vol.10 No.-

Al doped Zinc Oxide(ZnO:AI) films, which is widely used as a transparent conductor in optoelectronic devices such as solar cell, liquid crystal display, plasma display panel, thermal heater, and other sensors, were prepared by using the capacitively coupled DC magnetron sputtering method. In this paper the effect of doping amounts of Al₂0₃ on the electrical, optical and morphological properties were investigated experimentally. The results show that the structural and electrical properties of the film are highly affected by the doping. The optimum growth conditions were obtained for films doped with 2 wt% of indium which exhibit a resistivity of 8.5×10^(-4)Ω-cm associated with a transmittance of 91.7 % for 840 nm in film thickness in the wavelength range of the visible spectrum.

In this paper, we mention he fabrication of Sr ferrite plastic magnet. In order to compose Sr ferrite, first, a little CaO, SiO₂, Na₂SiO₃, and Al₂O₃ are added to SrO5.9Fe₂O₃. Then, the composition is calcinated at 1225℃ under N₂ enviroment for 1 hourwith addition of PVA 5wt% solution. The carbon coating method increase grinding effect on powder fabrication. To fabricate anisotropic Sr ferrite plastic magnet, 80-89wt% of Sr ferrite and polyamide6 are kneaded and then 0-12kOe of magnetic field is applied. On magnet fabrication, an optimal condition of injection mold is obtained under the injection temperature 270℃, the injection pressure 120㎏/㎠, the magnetic field 8kOe and magnetic field applied time 8sec. As the result of experiments, we obtain (BH)max = 2.09MGOe property on anisotropic plastic magnet which is fabricated by using injection mold method in magnetic field.
