This paper investigates student responses to CBLI(Content-Based Language Instruction), considered to be a prerequisite for CBI(Content-based instruction) in EFL situations. Even though a growing number of Korean universities have implemented CBI, English-medium instructions are criticized and lead to a number of issues. Straight(1997) divided CBI into CBLI focusing on language teaching and CBCI(Content-Based Content Instruction) focusing on subject matter. Seo(2010) suggested a modified version of CBI and contended CBLI should precede CBCI in order for students to be prepared for CBI. To lower students' affective filter, instruction was delivered in Korean in CBLI, but students received language input from authentic materials. Based on Seo's(2010) suggestions, an experimental class was conducted with 3 university students using the script of Desperate Housewives(2006) as study material. The teacher encouraged students to the content and avoided linguistic explanation as much as possible. The results and implications were as follows: first, CBI ought to be modified in EFL contexts because students seem to be obsessed by language learning where content learning should be a primary concern; second, it is necessary to enlighten students to the fact that a primary concern of content is related to language development; third, teachers need to monitor students frequently so that they maintain their interest in the content.

Objective : This study aims to investigate the relationship between addictive mobile phone use and post-traumatic stress disorder (PTSD) symptoms in bullies who experienced school violence. Methods : The study subjects consisted of 97 adolescents in The Foundation for Preventing Youth Violence after school violence. The participants conducted self-report questionnaire for addictive mobile phone use and Impacted Event Scale-revised-Korean version (IES-R-K). Partial correlation and multiple logistic regressions were performed. Results : The scores related to addictive mobile phone use were correlated with total score (r=0.21, p=0.04), avoidance score (r=0.21, p=0.04) and intrusive score (r=0.26, p=0.01) related to PTSD symptoms on the IES-R-K. Intrusive score related to PTSD symptoms on the IES-R-K were significant risk factor for addictive mobile phone use (O.R=1.25, 95% CI=1.12-1.39). Conclusion : This data supports that PTSD intrusive symptoms could be predictable factor of addictive mobile phone use. An appropriate intervention about PTSD symptoms might play a useful role in preventing addictive mobile phone use in bullies of school violence.

서지영,박미란,김창선,손형대,조동일,유남수,Seo, Jee-Young,Park, Mee-Ran,Kim, Chang-Sun,Son, Hyung-Dae,Cho, Dong-Il,Rhu, Nam-Soo 대한결핵및호흡기학회 1998 Tuberculosis and Respiratory Diseases Vol.45 No.1

연구배경: 최근 폐암은 전세계적인 증가 추세에 놓여 있을 뿐 아니라 서구에서는 여성 폐암 환자의 비율이 크게 늘고 있고 조직학적으로는 이미 선암이 가장 많은 비율을 차지하고 있는 등의 임상적인 면에도 변화가 생기고 있어 본과에서도 최근의 환자들에 대한 임상적 고찰을 통해 이러한 흐름을 파악해 보기로 하였다. 방 법: 1990년 1월부터 1996년 7월까지 본과에 입원하여 원발성 폐암으로 진단받은 212예를 대상으로 하여 연령별 및 성별로 나누고 내원 당시의 증상, 흡연 습관, 진단방법 및 진단양성율, 조직학적 및 병기별 분포와 치료 방법등에 따라 세분하여 관찰하였다. 곁 과: 1) 총 212예 중 남성이 178예, 여성이 34예로 5.2 : 1의 성비를 보였으며 연령별로는 60대가 35.4%로 가장 많았고 40대 미만의 예는 5.2%였다. 2) 주증상은 기침, 호흡곤란, 흉통 등의 순이었으며 초발 증상 발현 이후 내원까지의 기간은 대부분 3개월 이내(57.7%)였고, 1년 이상이 지나 내원한 경우도 13예(6.5%)였으며 1980년대를 기점으로 조기 내원율이 크게 증가하였다. 3) 전체 환자 중 흡연자는 77.2%였으며, 편평상피 세포암과 소세포암 환자에서 흡연자의 비율은 각각 88.4%, 85.7%로 높은 상관관계를 보이는 반면 선암의 경우는 55.7% 가 흡연자였다. 4) 조직학적으로 편평상피세포암이 44.8%로 가장 많았으며 이어 선암(30.7%), 소세포암(17.0%), 대세포암(3.8%) 순으로 선암이 증가 추세에 있고, 병기별로는 비소세포암의 경우 제 IIIb 병기 이상의 수술이 불가능한 경우가 72.1%였으며 소세포암의 경우는 제한기와 전신기가 각각 48.6%, 51.4%로 비슷하게 나타났다. 5) 진단양성율은 단순객담세포검사의 경우 75.3%, 경기관지 조직생검시 65.7%였으며, 임파절 흡인검사 95.8%, 경피적 폐침흡인검사 94.6%이고 개흉검사상에서는 100% 진단 가능했으며 전반적으로 과거에 비해 진단율이 향상되었다. 6) 내원당시의 활동 능력은 ECOG 1(46.7%), 0(26.2%)의 순으로 비교적 양호하였고, 진단 이후 69.3%의 환자에게 화학 혹은 방사선 치료가 시행되었고, 수술을 받은 경우는 7.5% 에 불과했다. 곁 론: 본 연구에서는 아직 편평상피세포암이 가장 많으나 과거에 비해 흡연파 비교적 상관관계가 적은 선암이 꾸준한 증가 추세에 있어 흡연 이외의 다른 발암 기전에 관한 관심이 요구되며 진단 당시 진행된 병기에 비해 양호한 활동 능력을 보이는 바 폐암의 선별 검사 및 조기진단의 중요성이 강조되나 아직까지 생존율을 크게 증가시킬 수 있는 뚜렷한 치료 방법이 없는 관계로 무엇보다 금연등 예방이 중요하다고 생각한다. Background: Lung cancer continues to increase worldwide. Also, the proportion of female patients incease and adenocarcinoma is the predominant histological type among lung cancer in many western countries. So, we studied these current trends of lung cancer by clinical approach of recent patients from our department Method: We conducted a retrospective analysis on 212 subjects who were diagnosed with lung cancer at the department of chest medicine in National Medical Center between January 1990 and July 1996. The contents of analysis were patient's profile, clinical manifestation, smoking habits, accuracy of diagnostic methods, histological cell type, staging and treatment, etc. Results: The results were as follows. 1) The ratio of male to female was 5.2 : 1. The peak incidence of age was 7th decade(35.4%). 2) Chief complaints were cough, dyspnea and chest pain, etc. The most common duration of symptoms before the first admission was less than 3 months(57.7%). On the other side, duration more than 1 year represented 6.5%. The early diagnosed patients has been increased from the 1980s. 3) Smokers among the total patients were 77.2%. The proportion of smokers in sqamous cell carcinoma, small cell carcinoma and adenocarcinoma were 88.4%, 85.7% and 55.7%, respectively. Smoking history and histological cell type were correlated in squamous and small cell carcinoma. 4) Squamous cell carcinoma is still the predominant histological type (44.8%), but, adenocarcinoma increased more than the previous study(30.7%). The other histological types were small cell carcinoma(17.0%) and large cell carcinoma(3.8%) in order of their proportions. 5) The accuracy of diagnostic methods were as follows: sputum cytology 75.3%, bronchoscopic biopsy 65.7%, lymph node aspiration cytology 95.8%, percutaneous lung aspiration cytology 94.6% and open lung biopsy 100%. The general accuracies of diagnostic methods were improved than previous studies. 6) Performance status scales on admission were relatively good. After diagnosis, chemotherapy and/or radiotherapy were undertaken in 69.3% of the patients, and only 7.5% of the patients were operated. Conclusion: In our study, squamous cell carcinoma is still the predominant histological cell type, but, adenocarcinoma continues to increase. Because adenocarcinoma is less correlated with smoking habits, further evaluation of other carcinogens than smoking is requested. Screening and early diagnosis of lung cancer is important for good performance status scales in spite of advanced stages. But, we think that the prevention, for example, stop smokings is more important as because of no perfect treatment for lung cancer.

Purpose: We evaluated the thickness of RNFL and optic nerve head parameters with age in normal eyes using Spectral-Domain Optical Coherence Tomography (SD-OCT). Methods: A total of 128 normal Korean volunteers in different age groups were recruited (age range, 20-70 years). Results: A significant negative correlation in average RNFL thickness with increasing age was found. The inferior areas (130.31 ± 3.33 μm) were significantly thicker than other areas (superior area 119.05 ± 2.12 μm, nasal area 71.80 ± 0.57 μm, temporal area 77.72 ± 0.16 μm). The average C/D ratios (mean 0.38 ± 0.14) and vertical C/D ratios (mean 0.35 ± 0.11) both showed significant increases with age, and the vertical C/D ratio correlation coefficient was higher (average C/D ratio r = 0.249, vertical C/D ratio r = 0.537). However, rim area, disc area, and cup volume were not correlated with age. Conclusions: From these findings, we conclude that, in normal Koreans, the mean RNFL thickness decreases and the C/D ratio increases with age, with the increase in the vertical C/D ratio being greater.

임플랜트 지지 고정성 국소의치의 임상적, 방사선학적 평가

서지영,심준성,이재훈,이근우,Seo Ji-Young,Shim June-Sung,Lee Jae-Hoon,Lee Keun-Woo 대한치과보철학회 2006 대한치과보철학회지 Vol.44 No.4

Statement of problem: A conventional 3-unit fixed partial denture design with a pontic between two retainers is the most commonly used. However in cases where the mental nerve is in close proximity to the second premolar, a cantilever design can be considered. As such, logical and scientific evidence is lacking for the number and position of implants to be placed for partially edentulous patients, and no clear-cut set of treatment principles currently exist. Purpose : The purpose of this study was to evaluate prognosis of implant-supported fixed partial dentures and to compare changes in bone level which may rise due to the different factors. Material and method : The present study examined radiographical marginal bone loss in patients treated with implant-supported fixed partial dentures (87 prostheses supported by 227 implants) and evaluated the influence of the span of the pontic, type of the opposing dentition. Clinical complications were studied using a retrospective method. Within the limitation of this study. the following result were drawn Result, 1. Seven of a total of 227 implants restored with fixed prostheses failed, resulting in a 96.9% success rate. 2. Complications encountered during recall appointments included dissolution of temporary luting agent (17 cases), porcelain fracture (8 cases), loosened screws (5 cases), gingival recession (4 cases), and gingival enlargement (1 case). 3. Marginal bone loss, 1 year after prosthesis placement, was significant(P<0.05) in the group that underwent bone grafting, however no difference in annual resorption rate was observed afterwards. 4. Marginal bono loss, 1 year post-placement, was greater in cantilever-type prostheses than in centric pontic protheses (P<0.05). 5. Marginal bone loss was more pronounced in posterior regions compared to anterior regions (P<0.05). 6. The degree of marginal bone loss was proportional to the length of the pontic (P<0.05). Conclusion: The success rate of implant-supported fixed partial dentures, including marginal bone loss, was satisfactory in the present study. Factors influencing marginal bone loss included whether bone graft was performed, location of the pontic (s), location of the surgical area in the arch pontic span. Long-term evaluation is necessary for implant-supported fixed partial dentures, as are further studies on the relationship between functional load and the number of implants to be placed.

서지영,Seo, Ji Yeong 한국데이터정보과학회 2015 한국데이터정보과학회지 Vol.26 No.2

This study was to investigate factors influencing the school adjustment according to gender and body mass index (BMI) of middle school students who participated in the 2nd-wave Korea Children and Youth Panel Study (KCYPS). This study used a crosssectional design with secondary analysis with KCYPS. The variables were parental interest, behavioral problem, aggression, attention problem, somatic symptom, social withdrawal, depression, and academic achievement. The data were analyzed with descriptive statistics, Pearson's correlation coefficients, and multiple regressions. School adjustment was significantly associated with academic achievement high, explaining 11.3~19.1% of the variance in boys. School adjustment was significantly associated with attention problem, explaining 14.9~42.4% of the variance in girls. Factors influencing school adjustment were significantly different according to gender and BMI. To improve the school adjustment, it is necessary to develop gender-specific school adjustment promotion programs according to BMI. 본 연구는 청소년 초기인 중학교 2학년 남녀학생의 BMI 정도에 따라 학교적응의 영향요인이 어떻게 다른지 확인하고자 시도되었다. 본 연구는 "한국청소년정책연구원"에서 제공한 '한국아동청소년 패널조사 (Korea Children and Youth Panel Study; KCYPS) 2010 중1 패널의 2차년도 데이터를 활용'하였다. 설명변수는 부모의 관심, 문제행동, 공격성, 주의집중 문제, 신체증상, 사회적 위축, 우울 및 학업성취도 (더미변수 처리)이다. 서술적 통계, 피어슨의 상관계수 및 다중회귀분석을 실시하였다. 회귀분석 결과, 남학생은 학업성취도 상이 공통된 영향요인이었으며, 설명력이 11.3 19.1%였다. 여학생은 주의집중 문제가 공통된 영향요인이었으며, 설명력이 14.9~42.4%였다. 학교적응의 영향요인들은 남녀학생의 BMI 정도에 따라 다르게 나타났다. 본 연구결과를 토대로 추후 중학생의 학교적응을 향상시키기 위해서는 BMI 정도에 따라 성별 특성에 맞춘 적응 증진 프로그램 개발이 필요하다.
