This study aims to analyze how focus on form (FonF) techniques are reflected on the sixth-grade elementary school English textbooks in Korea. The subjects of the study were task activities of five sixth-grade English textbooks based on the 2015 revised curriculum, and the textbook activities were analyzed by revised criteria for task analysis used in Kim Jung-eun s (2017). Data was processed by the SPSS 12.0 program and analyzed through a chi-squared test. The results of this study show that, according to the average frequency of tasks in all textbooks, practice tasks were used approximately twice as much as the consciousness-raising tasks. The tasks in each textbook accounted for a large portion in the order of grammar practice, interpretation tasks, and grammar activities. It has been confirmed that the difference between the amount of the raising awareness task and that of the practice task in the textbooks and between the amount of the grammar exercise task and that of the grammar practice activity task is statistically significant. Therefore, it is necessary to increase consciousness-raising tasks when developing textbooks and present more diverse tasks for raising awareness.

연구목적 : 손상된 유전자의 회복은 암의 발생 및 예방에 중요한 역할을 한다. 잘못된 염기의 제거 및 회복에 중요한 역할을 하는 OGGI 유전자의 다형성이 방광암에 어떠한 작용을 하는지를 환자-대조군 연구를 통해서 조사하였다. 대상 및 방법: 방광암 환자 168명과 건강인 672명을 대조군으로 하여 genomic DNA를 이용하여 SSCP (single-stranded conformational polymorphism), direct DNA sequencing 및 restriction fragment length polymorphism (RFLP) 방법을 통해 환자 및 대조군사이의 OGGI 유전자의 다형성을 조사하였다. 결과: 건강 한국인에서 OGGI 유전자의 유전형을 조사한 결과 econ 6의 Pro324Pro 부위(lb type)와 exon 7의 Ser326Cys 부위 (la type)에 유전자의 다형성이 있음을 발견하였다. Codon 324는 silent polymorphic site였으나 codon 326은 C→G로 nucleotide가 바뀌어 amino acid가 serine→cysteine으로 바뀌는 polymorphic site였다. 대조군에서 codon 326은 Ser326Ser 형이 127례 (18.9%), Ser326Cys 형이 363례 (54.0%) 및 Cys326Cys 형이 182례 (27.1%)이었으며, 168명의 방광암 환자군에서는 Ser326Ser 형이 44례 (26.2%), Ser326Cys 형이 87례 (51.8%)이고 0ys3260ys 형이 37례 (22.0%) 이었다(p=0.034) 즉 Cys326Cys 형 및 Ser326cys 형에 비하여 Ser326Ser 형에서 방광암이 생길 확율이 1.52배 (95% CI=0.439-0.969) 높았다 특히 40세 미만의 남자의 경우 Ser326Ser 형에서 방광암 발생확률이 다른 유전형에 비하여 6.1배 높았다. 결론: OGGI 유전자의 유전형은 서구인과 판이하게 달랐으며 방광암에서는 이 유전자의 변이가 빈번할 뿐아니라 codon 326의 Ser326Ser 형에서는 다른 유전자형에 비하여 방광암이 발생할 확률이 1.5배 이상 높았다. 특히 한국인 40세 미만의 남자에서는 방광암 발생확률이 6배이상 높았다. 본 연구결과 OGGI codon 326의 유전적 다형성은 방광암의 종양화 과정과 관계가 있을 것으로 여겨지며 특히 40세 미만의 한국 남자의 경우는 더욱 밀접한 관계가 있을 것으로 사료된다. Purpose: A repair of damaged DNA has been shown to be involved in the susceptibility to cancer development and prevention. Therefore, it is worth investigating genetic polymorphisms of the OGGl gene associated with the gene repair mechanism. In this study, we examined a possible association of genetic ploymorphisms in OGGl with the risk of bladder tumor. Materials and Methods: Hospital based, case-control investigation was carried out in 168 primary bladder tumor patients and 672 control subjects. We performed the SSCP, PCR-based restriction fragment length polymorphism (RFLP) and direct DNA sequencing to characterize the genetic polymorphism of OGGI in both cases and oontrols. Results: We found two polymorphic sites in OGGl. A Ser/Cys polymorphism at codon 326 (la type) in exon 7 was associated with an exchange of amino acid. Another polymorphic site at codon 324 (1b type) in econ 6 was silent. The association between codon 326 Polymorphism and the risk of the bladder tumor was examined by a age-sex adjusted analysis. We found that the distribution of OGGl Ser326Cys genotypes of controls(Ser/Ser, 18.9% ; Ser/Cys, 54.0% ; Cys/Cys, 27.1%) was significantly different from that of bladder tumor patients (36.2%, 51.8% and 22.0%, respectively) (p = 0.034, adjusted OR = 0.652, 95% Cl = 0.44 - 0.97). Especially, bladder tumor risk in Korean male under 40 years old was approximately 6 times higher than over 40 years old males. Conclusion : Our data suggested that Ser326cys polymorphism at codon 326 of OGGl male below 40 years old in Korea significantly increased the risk of tumorigenesis in the urinary bladder (p = 0.015, adjusted OR = 0.165, 95% CI = 0.04 - 0.75) Our results suggest that the OGGl Ser326Cys Polymorphism might play a role in the tumorigenesis of the bladder.

조혈모세포이식 환자의 삶의 질에 대한 연구 : 화학요법 환자 및 정상인과의 비교

김병수,서재홍,최철원,김열홍,김준석,김정아,손상균,김재석,이경희,이제중,정익주,곽재용,안진석,이정애,박영석 대한조혈모세포이식학회 1999 대한조혈모세포이식학회지 Vol.4 No.1

연구배경: 조혈모세포이식후 신체 및 정신적 장애의 정도가 얼마나 환자의 '삶의 질(QOL)'에 영향을 미치는지에 대하여 외국에서는 연구들이 활발히 진행되고 있다. 그러나 우리나라에서는 조혈모세포이식이 비교적 활발히 시술되고 있음에도 불구하고 이에 대한 연구가 미미한 실정이었다. 연구자 등은 우리 나라에서 조혈모세포이식을 받은 환자들의 QOL은 어떤지를 알아보고자 하는 목적으로 본 연구를 시행하였다. 방법: 본 연구에 참여한 각 기관에서 조혈모세포이식을 받고 주된 치료가 끝난 후 1999년 2월 시점에서 최소 3개월이 지나고 관해상태에서 일상생활을 영위하고 있는 재생불량성 빈혈과 급성 및 만성 백혈병 환자들을 각각 자가 및 동종 조혈모세포이식을 시행받은 조혈모세포이식군(1군)과 항림프구 글로불린, 공고요법 등으로 치료를 끝낸 화학요법군(2군)으로 분류하고 연구자 병원에 내원한 건강한 환자 보호자들로 이루어진 정상대조군(3군)을 선정하여 각각의 QOL을 비교, 분석하였다. QOL의 측정은 EORTC QLQ-C30 문항을 우리나라의 실정에 맞게 번역하여 사용하였다. 결과: 조혈모세포이식군(1군)은 53명, 화학요법군(2군)은 57명, 정상대조군(3군)은 55명 이었고, 성별, 나이, 질환별 분포, 검사시점 등에서의 유의한 차이는 없었다. 각 군간의 QLQ-C30 평균 점수를 비교한 결과, 전반적인 삶의 질에서는 1군이 73.5, 2군이 51.7, 3군이 79.3으로 2군이 1.3군보다 낮았고 역할 및 사회기능은 각각 1군이 64.3/68.9, 2군이 57.6/70.3, 3군이 85.2/85.5로 1,2군이 3군에 비하여 낮았다.(P<0.01). 또한, 오심/구토가 1군은 8.7, 2군은 4.5, 3군은 3.2로 1군이 2, 3군보다 높았으며 통증은 1군은 17.0, 2군은 19.2, 3군은 9.6으로 1,2군이 3군에 비하여 높았다(p〈0.01). 기타 신체, 감정, 인식기능 및 피로에서는 각군간에 유의한 차이를 발견할 수 없었다. 결론: 본 연구에 참여한 조혈모세포이식환자들의 전반적인 삶의 질은 화학요법을 받은 환자들보다 우월하면서 정상인들과 유사하였으나 역할기능 및 사회기증, 통증에서는 화학요법 환자들처럼 정상인들에 비하여 열악하였고 오심/구토는 화학요법 환자들 및 정상인에 비하여 심한 양상을 보였다. 그러므로 본 연구를 바탕으로 하여 국내 실정에 맞는 QOL 측정 방법을 개발하고 조혈모세포이식을 시행받는 환자들의 삶의 질에 관한 연구들이 향후 계속 진행되어야 하리라고 생각된다. Background: It is very important to endow patient with satisactory quality of life (QOL). However, little is known about QOL after hematopoietic stem cell transplantation (HSCT) in Korea. In this study we tried to measure QOL in the patients treated with HSCT and compare QOL scores with those of patients treated with usual chemotherapy and normal populations. Methods: The QOL evaluation was performed with EORTC QLQ-C30 questionnaires interpreted to Korean language. The study populations were consisted with 53 patients treated with HSCT (Group 1), 55 patients treated with usual chemotherapy (Group 2), and 55 normal populations (Group 3). The QLQ-30 scores of each group were evaluated and compaired with x² test. Results: Global quality of in group 1, 3 (score: 73.5, 79.3, respectively) were higher than that (score: 51.7) of group 2. Role and social function were lower in group 1, 2 (score: 64.3/68.9, 57.6/70.3, respectively) than those (score: 85.2/85.5) of group 3. The degree of nausea and vomiting was more severe in group 1 (score: 8.7) than those of group 2, 3 (score: 4.5, 3.2 respectively). Pain scores of group 1, 2 (score: 17.0, 19.2, respectively) were more higher than that of group 3 (score: 9.6) In other parameters of QLQ-C30, there was no significant difference between each groups. Conclusion: Our perliminary result may suggest that HSCT is not necessarily associated with deterioration of QOL. This underlines the necessity of undertaking perospective studies using reliable and well-validate methods for measuring QOL

Background and Purposes: Over the past three decades, numerous studies performed in Korea have reported that job stress is a determinant risk factor for chronic diseases and work disability. Every society has its own culture and occupational climate particular to their organizations, and hence experiences different occupational stress. An occupational stress measurement tool therefore needs to be developed to estimate it objectively. The purpose of this study is to develop and standardize the Korean Occupational Stress Scale (KOSS) which is considered to be unique and specific occupational stressors in Korean employees. Subjects and Methods: Data were obtained from the National Study for Development and Standardization of Occupational Stress (NSDSOS Project: 2002-2004). A total of 12,631 employees from a nationwide sample proportional to the Korean Standard Industrial Classification and the Korean Standard Occupational Classification were administered. The KOSS was developed for 2 years (2002-2004). In the first year, we collected 255 items from the most popular job stress measurement tools such as JCQ, ERI, NIOSH and OSI, and 44 items derived from the a qualitative study (depth interview). Forty-three items of KOSS, in the second year, were retained for use in the final version of the KOSS by using Delphi and factor analysis. Items were scored using conventional 1-2-3-4 Likert scores for the response categories. Results: We developed eight subscales by using factor analysis and validation process: physical environment (3 items), job demand (8 items), insufficient job control (5 items), interpersonal conflict (4 items), job insecurity (6 items), organizational system (7 items), lack of reward (6 items), and occupational climate (4 items). Together they explained 50.0% of total variance. Internal consistency alpha scores were ranged from 0.51 to 0.82. Twenty-four items of the short form of the KOSS (KOSS-SF) were also developed to estimate job stress in the work setting. Because the levels of the subscales of occupational stress were gender dependent, gender-specific standard norms for both the 43-item full version and the 24-item short form using a quartile for the subscales of KOSS were presented. Conclusion: The results of this study suggest that KOSS might be an appropriate measurement scale to estimate occupational stress of Korean employees. Further and more detailed study needs to be conducted to improve the validity of this scale.

Objectives : Abnormalities of cognitive responses to verbal and visual distracter in schizophrenia have been demonstrated in numerous studies but little is known about three dimensional visuospatial-motor distracter processing. The purpose of this study was to investigate the vulnerability of patients with schizophrenia to three dimensional visuospatial-motor distracter. Methods : 14 patients with schizophrenia and 14 normal volunteers were assessed on three dimensional maze tasks requiring on working memory and reasoning ability in the virtual reality environment. Performances were compared according to with- or without-distracter conditions. Results : Patients with schizophrenia showed significantly lower performances than normal control group on cognitive flexibility, simple motor function or motor control and motor coordination, working memory span and delayed performance times. The performance index tended to be more deteriorated, but not significantly, in with-distracter condition than in Without-distracter condition in schizophrenia. Conclusions : Patients with schizophrenia tend to be vulnerable to visuospatial-motor distracter which simulate the real world of three dimensional environment.

정동섭,양윤재,이정형 대한건축학회 2005 대한건축학회논문집 Vol.21 No.3

The purpose of this study is to analyze the methods of the Building Envelope Design in foreign cities. The Study is especially focused on the Integrated Control Methods of Building Envelope Plan as District Level in a commercial area. In generally, There have been the methods to control development density such as FAR, BCR, Building Height to manage efficiently urban land-use in district Level. However, each element of the methods has been separately adapted to urban management plans, Urban Design Guidelines, District Detailed Plans, and even Zoning. Moreover, there have been suggested some limits to adjust them to control the contemporary building density and form. Therefore, this paper defined the concept of the Building Envelope Design Control, sorted it out the guideline elements and suggested the control methods through the comparative analysis of the Envelope Plan of foreign cities.

정상인에서 양가감정과 관련되 뇌 영역 : 양전자방출단층촬영 상관 연구

정영철,석정호,전지원,박해정,이종두,김재진 大韓神經精神醫學會 2006 신경정신의학 Vol.45 No.3

Objectives : The present study investigated the brain regions that correlate with ambivalence in schizotypy, a latent personality organization that is proposed to precede and contribute to the liability of developing schizophrenia. Methods : Using ^(18)F-FDG PET scan, we investigated the brain activity of twenty one normal healthy subjects during the resting state. Questionnaires, including the Korean Version of Schizotypal Ambivalence Scale (K-SAS), were administrated after the scan in order to assess the self-rated individual differences in ambivalence. Results : The Schizotypal Ambivalence Scale (SAS) scores showed positive correlation with the metabolic rates in the left parahippocampal gyrus and the fornix. In contrast, the Ambivalence over Expression of Emotion Questionnaire (AEQ) scores showed negative correlation with the metabolic rates in the right putamen. Although scores of the two ambivalence scales Correlated positively (Pearson correlation coefficient 0.477, p<0.050), there was no substantial overlap between the neural correlates. Conclusion : This study suggests that the hippocampal complex, which dysfunction has been reported to correlate with impaired information processing in schizophrenia, may underlie schizotypal ambivalence.

정필두,김은정,엄민식,서정원,윤석중,김종석,이상철,김원재 충북대학교 의학연구소 2001 忠北醫大學術誌 Vol.11 No.2

연구목적: TNF-α는 일부 종양의 종양화 과정과 관련이 있는 것으로 알려져 있다. 본 연구는 TNF-α 발현에 영향을 미치는 TNF-α 촉진자 -308 부위의 유전적 다형성이 방광암과 관련이 있는지 유무를 알고자 시행하였다. 대상 및 방법: 유전자 분석을 위하여 환자 113명 및 대조군 109명으로부터 혈액을 채취하여 genomic DNA를 분리한 후 PCR-RFLP 및 direct DNA sequencing을 통하여 TNF-α유전자의 다형성을 조사하여 방광암의 발생, 병기 및 분화도와 비교 검토하였다. 결과: TNF-α 촉진자 -308 부위의 유전형은 대조군에서는 GG형이 83.5%(90례 및 GA형이 16.5%(19례)로 관찰되었으며 AA형은 없었다. 환자군에서는 GG 형이 85.4%(97례), GA형 및 AA형은 각각 13.1%(15례)및 0.8%(1례)에서 관찰되었다. 두 군 모두에서 GG형이 가장 많이 나타났으며 다음으로 GA형을 보이고 AA형은 1례의 방광암 환자에서만 관찰되었다. -308부위의 경우도 두 군 사이에 유전자형의 차이는 없었다(p=0.259) 분화도별 분포를 보면 grade I이 20례, grade II가 49례, grade Ⅲ은 34례였고 병기별로 표재성인 경우가 90례였으며 침윤성은 14례였다. 분화도가 나빠질수록 GA형이 증가하였다(p=0.04). 그러나 병기와 TNF-α promoter -308부위의 유전자형 사이에는 유의한 상관 관계가 없었다(p=0.123). 결론: 방광암 환자의 혈액에서 GA genotype이 관찰되는 경우, 분화도가 나쁠 가능성이 매우 높기 때문에 좀 더 적극적인 치료와 세밀한 추적관찰을 함으로써 방광암으로 인한 사망과 암의 진행을 예방할 수 있을 것으로 기대한다. Purpose : Tumor necrosis factor-alpha (TNF-α) is involved in tumorigenesis of several cancers as an endogenous tumor promoter. The purpose of this study was to investigate whether genetic polymorphism of TNF-α promoter region (-308) was associated with human bladder tumor. Materials and Methods: The DNA from 113 and 109 respective blood samples of bladder tumor Patients and control group was analyzed by PCR-based restriction fragment length polymorphism (RFLP) and direct DNA sequencing methods to characterize the genetic polymorphism of -308 promoter region of the TNF-α gene in bladder tumor patients. We compared the association of bladder tumor with genetic Polymorphism of TNF-α promoter region(-308) in relation to the stage, grade, recurrence and progressio. Results : Eighty-six percents(97/113) of bladder tumor patients and 83.5% (90/109) of control group showed genotype GG at -308 region of TNF-α. Difference in genetic variations of TNF-α promoter (-308) did not exist between bladder tumor patients and control group(p=0.259). Tumor grade was significantly related to the GA genotype (p=0.04). The higher is the grade in bladder tumor, the more frequent was the GA genotype. Tumor stage, recurrence and progression were not significantly associated with genetic polymorphism of TNF-α promoter region (-308). Conclusion: The GA genotype of TNF-a promoter region (-308) had a significant impact on TNF-α production and was related to higher grade tumor compared to GG genotype. TNF-α serum levels in bladder tumor patients were significantly higher than controls. These data suggested that TNF-α might involve the tumorigenesis of the bladder rather than treatment or prevention of bladder tumor.

평택시 미군기지 주변 주민의 비행기 소음과 청각학적 평가결과의 관련성

정종도,김현주,정재윤,노상철,권호장 大韓産業醫學會 2009 대한직업환경의학회지 Vol.21 No.2

목적: 비행기소음이 청각에 대한 포괄적인 영향을 파악하기 위하여 이명 및 난청과의 관련성을 규명하고자 한다. 또한 변조이음향방사 검사를 통해 비행기소음의 난청에 대한 영향을 객관적으로 파악하고자 하였다. 방법: 연구 대상지역은 평택시에 위치한 두 개의 미군기지(K-55, K-6) 주면 8개 마을로 선정하였고 대조지역은 비행장에서 10 km 이상 떨어진 5개 마을이었다. 연구대상은 전도성 난청자와 순음청력검사에 협조가 불가능한 경우를 제외하고 노출군 492명 , 대조군 200명이었다. 환경소음은 2005년 12월 9일, 노출지역 8개, 대조지역 2개 마을을 동시에 주간 8시간 측정하였다. 구조화된 설문지를 통해 이명 여부와 그 불편감을 조사하였고, 이명 불편감은 구조화된 '이명 불편감 설문지'를 통해 파악한 뒤감정적, 기능적, 재앙화적 측면에서의 점수를 합산하여 산출하였다. 청력평가를 위해 0.5, 1, 2, 3, 4, 6, 8 kHz에 대하여 순음청력검사와 1582, 2003, 3175,4007 Hz에 대하여 번조이음향방사 검사를 시행하였다. 비행기소음의 노출특성 및 혼란변수의 성차를 고려하여 성별층화분석을 했고, 연속변수는 일반선형모델(general linear model)을 사용하여, 범주형 변수는 로지스택 회귀분석을 사용하여 분석하였으며, 보정한 혼란변수는 연령, 교육정도, 스트레스 반응척도, 군대소음, 농업소음, 직업소음이었다. 결과: 이명 증상 호소율은 남성에서 노출군 47.3%, 대조군 27.6%이었고, 여성에서 노출군 50.8%, 대조군 28.5%이었으며, 그 대응비는 남성에서 2.06(95% CI:1.09~3.88), 여성에서 1.97(95% CI: 1.17~3.30)이었다. 이명 불편감 영역별 점수는 남녀 모두에서 감정적, 기능적, 재앙화적 측면에서 노출군이 비노출군보다 유의하게 높았다(p<0.001). 순음청력검사결과 남성에서는 우측 귀 0.5, 1 kHz에서, 여성에서는 좌측 귀 0.5, 1 kHz와 우측 귀 0.5, 1, 2, 3, 4, 6 kHz 주파수 영역에서 노출군의 청력역치가 대조군보다 유의하게 높았다(p<0.05). 변조이음향방사 검사결과, 남성에서는 두 군간에 비정상률의 차이가 없었으나, 여성의 비정상률은 좌측 귀 3175, 4007 kHz 영역에서 각각 1.92(95% CI:1.10~3.36), 2.71 (95% CI: 1.49~4.91), 우측 귀 각각 1.73(95% CI: 1.01~2.99), 1.78(95% CI:1.01~3.15)의 대응비를 보였다. 결론: 연구결과 수십 년간 군 기지의 비행기소음에 노출된 집단에서 이명과 이명 불편감이 대조군보다 유의하게 높았다. 순음청력검사는 노출군이 대조군보다 통계적으로 유의한 청력저하를 보였다. 변조이음향방사 검사는 여성 노출군에서만 대조군보다 통계적으로 유의한 비정상률을 보였다. 이로부터 비행기소음이 이명과 난청 등 삶의 질에 영향을 미치는 건강문제를 유발할 가능성을 확인할 수 있었다. Objective: To investigate the relationship between aircraft noise and the results of audiological evaluation on tinnitus and hearing loss among residents near United States military air-bases in Pyeongtaek city. Methods: Residents (n=492) exposed to aircraft noise were selected from eight villages near U.S. military air-bases (K-55 and K-6) in Pyeongtaek city. Residents (n=200) from five villages located at least 10km away from the air-base were selected for the control group. All participants completed a questionnaire on tinnitus and audiological evaluations included pure tone audiometry (PTA) and distortion Product otoacoustic emissions (DPOAE). Statistical analyses involved a general linear model and multiple logistic regression stratified by gender and data was a쏜usted by age, educational level, stress response index and noise type (i.e. military, agricultural and occupational). Results: The equivalent noise levels (Leq) in the vicinity of the air-field were 73.4~81.5 dB (A). Tinnitus prevalence was 47.3% and odds ratio (OR) was 2.06 (95% confidence interval (CI): 1.09-3.88) among noise-exposed males. Tinnitus prevalence was 50.8% and OR was 1.97(95% CI: 1.17~3.30) among noise-exposed females. Tinnitus handicap scores among exposed group were significantly higher in functional, emotional, and catastrophic subclasses (P<0.001). PTA revealed hearing thresholds among the exposed group of 0.5 and 1 kHz (male right ear), 0.5 and 1 kHz (female left ear) and 0.5, 1, 2, 3, 4 and 6 kHz on female right ear that were significantly higher than those of the unexposed group. No Significant difference in DPOAE was observed among noise-exposed mes. However, significant differences were evident for noise-exposed females at 3175 and 4007 Hz. ORs of right female ears 3175 and 4007 Hz were 1.73(95% CI: 1.01-2.99) and 1.78(95% CI: 1.01-3.15). ORs of left female ears at 3175 Hz and 4007 Hz were 1.92(95% CI: 1.10-3.36) and 2.71(95% CI: 1.49-4.91) Conclusions: Aircraft noise may adversely affect hearing function and tinnitus.
