Purpose: The purpose of this study was to investigate the relationships between the degree of smart phone addiction among adolescents and their depression and anxiety levels. Method: In this study, 379 high school students were selected using the convenient sampling method. The instruments used for this study were smart phone addiction measure, the CES-D (Center for Epidemiological Studies-Depression Scale), and the STAI (State-Trait Anxiety Inventory). Data were analyzed using the SPSS 20.0 program with descriptive statistics, t-test, ANOVA with Scheffe test, and Pearson’s correlation coefficient. Result: The mean score for smart phone addiction was 40.45±17.27, depression was 36.56±9.58, state anxiety was 44.00±9.61, and trait anxiety was 45.70±9.75. There were significant differences between the degree of smart phone addiction and the following variables: gender (t=-4.953, p<.001), hours of smart phone use per day (F=12.259, p<.001), types of frequently used features (F=3.485, p=.008), and satisfaction level for smart phone (F=5.18, p<.001). There were statistically significant relationships (p<.001) among degree of smart phone addiction, depression level, and state and trait anxiety levels. Conclusion: The results of this study suggested that there was a significant relationship between smart phone addiction and mental health, specifically, depression and anxiety among adolescents. Further research is needed to develop nursing strategies to provide care for adolescents who frequently utilize smart phones.

Acinar cell carcinoma is a rare tumor that represents 1~2% of al1 pancreatic cancers. Clinical and radiologic findings are inconclusive in this disease Acinar cell carcinoma is characterized by rapid progression and early metastasis, which lead to its poor prognosis. A 41-year-o1d man was admitted to our hospital for abdominal pain. Abdominal computed tomography (CT) and positron emission tomography-computed tomography (PET-CT) showed a splenic mass, which was being invaded by a pancreatic tail mass and which had increased ^(18)F-fluorodeoxyglucose (FDG) uptake Primary radical distal pancreatectomy and splenectomy were performed. Pathologic findings revealed an acinar cell carcinoma of the Pancreas The patient underwent a total gastrectomy three months later because of gastric recurrence Four months later, multiple hepatic metastases were discovered, and the patient underwent a left hepatectomy During treatment with capecitabine, there was no evidence of tumor progression for 14 months. We report a case of metastatic pancreatic acinar cell carcinoma, which did not progress for an extended period while the patient was being treated with capecitabme.

서로 다른 입자크기의 3층구조를 갖는 튜브형태의 한외알루미나 분리막은, 일반적으로 제조공정중 분리층에 결손부분이 발생하기 때문에 낮은 선택도 및 제거율을 보인다. 이와같은 결손부분을 보정 하고 보정전, 후의 분리막에 대한 기체장치에 의한 투과도(permeability) 및 선택도(selectivity)를 측정하였다. Colloidal silica 솔의 deposition에 기인하여 기체 투과율의 감소가 60%였다. 한외알루미나 여과막의 보정에 있어서 습도조절에 의한 선택적 적심법은 비록 deposition에 의한 문제점을 내포하고 있으나, 기체분리에서도 효과적인 방법이다. The 3-layer tubular type alumina membrane consisting of different pore size shows the decreased selectivity and rejection because of cracks in the separation layer generally occurred during the manufacturing process. For the comparing of native and modified membranes, the modified membranes were tested by permeability by gas equipments, selectivity for the gases after caulking. The permeabilities are decreased 60% for the gas caused by deposition of colloidal silica sol after caulking. In conclusion, the Alternative Wetting Method by humidity control had the effect for the modification of ultrafiltration alumina membrane for separation of gases, though having problem of deposition.

화학증폭형 감광제의 전산모사를 위한 PEB 변수 추출

서은정,오혜근 한양대학교 이학기술연구소 2002 이학기술연구지 Vol.4 No.-

노광 후 열처리 시 전열처리 후에 남아있던 유기 용매와 잔여물들이 중발하고 비보호 반응에 의한 다중 폴리머들이 분해되면서 자유 공간이 줄어들어 감광제의 두께가 줄어들며 동시에 감광제의 광학 상수들이 변한다. 이전에는 투과도 변화와 두께 변화를 측정한 후 다중 박막 간섭 이론을 적용하여 흡수계수를 구한 후 이를 이용하여 PEB 변수들을 구했었다. 하지만 실제 양산 라인에서 실리콘 웨이퍼를 사용할 경우 투과도 측정이 쉽지 않으므로 이러한 문제점을 극복하고자 계산한 k 대신에 실제로 n&k analyzer 로 측정한 흡수계수 k 를 적용하여 새로이 PEB 변수들을 추출해 보았다. 여러 열처리 조건에 따른 감광제의 특성 변화를 측정할 수 있었고, 그 결과를 사용하여 각 조건별 비보호 영역의 농도인 C_(as) 의 변화를 구하였다. The remaining solvent and residue evaporate during post exposure bake and the polymer is decomposed by do-protection reaction, and as a result the thickness reduction of photoresist eventually takes place. The optical parameters such as n and t of photoresist change from this physical property change during post exposure bake. The previous method to define post exposure bake parameters was measuring the transmittance and thickness variations of the resist to find absorption coefficient changes by applying multiple thin film interference theory to the measured data. However, it is not easy to measure the transmittance in a practical fabrication condition use of Si-wafer process. The absorption coefficient k was directly measured by n&k analyzer instead of using calculated one in order to get over this difficulty and the measured k is used to obtain the post exposure bake parameters. Various characteristic changes of the resist have been observed with respect to the various bake conditions and the concentration of do-protected site, C_(as) can be obtained for each condition.

A Shih-tzu(8-year-old, castrated male) was referred to the Veterinary Medical Teaching Hospital of Chungnam National University with the history of relapsing pruritus, recurrent dermatitis. On the physical examination, generalized erythema, otitis externa, alopecia and lichenification were observed. Using Favrot's criteria for diagnishing atopic dermatitis, 7 criteria were satisfied out of 8 criteria. After treatment for infection, intradermal skin test was performed(positive allergen : Df, Dp). And then immunotherapy was performed, but clinical signs were not getting better. Next treatment of glucocorticoid shown little improvement of clinical signs, and adverse effect(diarrhea) was shown after cyclosporine application. So application of leflunomide which is used for human atopic dermatitis treatment in some case was planned. After 6 months of application of leflunomide, clinical signs were decreased gradually.

인터넷카페 게시판에 나타난 메이크업에 관한 내용 분석

서정희,이은정 울산대학교 2004 생활과학논문집 Vol.6 No.1

이 논문은 인터넷카페 게시판에 올려진 게시물들의 세부내용 중 메이크업 테크닉에 관한 내용과 유행 메이크업의 경향을 분석하여 메이크업에 관한 주제유목별 하위영역은 어떠한가를 살펴보고, 여성들이 주로 메이크업에 관해 어떠한 정보를 인터넷상에서 공유하고 있는지를 알아보고 그 내용들을 분석하였다. 인터넷 카페 게시판에 올려진 게시물에 나타난 메이크업을 관한 분석한 결과 다음과 같은 결론을 내릴 수 있다. 가장 많은 빈도를 나타내는 주제 유목으로는 눈에 관한 주제였고, 다음으로는 베이스메이크업, 입술유목, 마지막으로 얼굴형 유목아 가장 적은 빈도를 나타냈다. 그 내용들을 살펴보면 첫째, 눈 유목에서는 아이새도우에 가장 많은 관심을 가지고 있음을 알 수 있고, 여성들이 바라는 이상형의 눈인 커 보이고, 속눈썹이 길고 자기의 결점을 감출 수 있는 테크닉을 바라는 것으로 나타났다. 둘째, 베이스메이크업은 가장 피부색에 가깝게 화장을 하지 않은 듯한 느낌을 주기 위해 신경을 많이 쓰는 부분으로 나타났다. 셋째, 입술 유목에서는 맑고 투명함, 촉촉한 입술을 표현하는 립글로스에 치중되어 관심을 보여지고 있었고, 요즘 트렌드인 투명 메이크업과도 연관을 지을 수 있다. 마지막으로 얼굴형 유목에서는 요즘 흔히들 말하는 미인형 즉, 작고 갸름한 달걀형 얼굴을 바라고 있는 것을 반영하듯이 얼굴 작아지는 쉐딩(shading)표현으로 음영을 주어 입체감 있게 얼굴형을 커버하는 테크닉이 설명되어 있다. 그러므로 여성들은 자기의 결점을 감출 수 있는 메이크 업 테크닉과 서구형의 입체적인 얼굴형을 닮아가려는 것으로 보여진다. This paper is analyzed for methods and trend of make-up on the web board, including sub area of each topic in make-up, how to share an information about make-up in the internet between female user and analyzing that contents. I can conclude after analyzing articles about make-up on the web board in internet. The frequent field of topic is eye and next one is base make-up, lip and less frequent item is face. To investigate of contents First, they are interested in eye-shadow very much which is skill of make bigger eye, longer eye lashes and concealing their flaw through make-up. Second, they attention on base make-up similar with skin color like dose not make-up on the face. Third, they are interested inusage of lip-glosse for moisturing lips and it also connects with make-up of transparency. Finally, they want to be type of “pretty woman” such as small and slim face, so it can be by “shading” skill, for expressing contrast. Therefore, woman want to conceal their flaw by some of skill and want to be face of western type.
