Objectives : This study aims to estimate the prevalence of the DSM-IV psychiatric disorders in Korean population using the Korean version of Composite International Diagnostic Interview (K-CIDI). Methods : Subjects were selected by taking multi-stage, cluster samples of 7,867 adult household residents, 18 to 64 years of age, in ten catchment areas. Total 78 trained interviewers administered the K-CIDI to the selected respondents, from June 1 to November30,2001. Results : Total 6,275 respondents completed the interview. Some 33.5% of respondents reported at least one lifetime disorder, 20.6% reported at least one-year disorder, and 16.7% reported at least one-month disorder. The most common lifetime disorders were alcohol abuse/dependence (17.24%), nicotine dependence/withdrawal (11.19%), specific phobia (5.16%), and major de-pressive disorder (4.25%). The lifetime prevalence of substance abuse/dependence (0.25%) and schizophrenia (0.16%) was very low. Nicotine and alcohol use disorder showed very high male/female ratio. Mood disorder and anxiety disorder were more prevalent among female than male. Conclusion : The prevalence of psychiatric disorders was high. In comparison with other studies, remarkable differences in distributions of psychiatric disorders across the areas and times were observed.

Objectives : One of the objectives of this study is to estimate the prevalence rates of psychiatric diagnoses in the combined populations of psychiatric hospitals, psychiatric nursing facilities and homeless asylums using the Korean version of the Composite International Diagnostic Interview (K-CIDI), which is a comprehensive and fully standardized interview schedule to assess psychiatric disorders for diagnosis. The Other objective is to compare with previously studied prevalence rates of Psy-chiatric diagnoses using the results of this study. Methods : The study subjects, aged from 181o 64 years, were randomly selected from 64,582 institutionalized population of psychiatric hospitals, Psychiatric nursing facilities and homeless asylums as of 30, June, 2001. Twelve trained interviewers administered the K-CIDI to the selected respondents. A total of 1,875 respondents (male 1,194, female 681) completed the interview. Results : The lifetime and one year prevalences of any diagnosis excluding nicotine dependence · withdrawal, anxiety disorder, eating disorder, somatoform disorder were 88.2% (male 88.1%, female 88.3%), and 65.8% (male 62.7%, female 73.7%), respectively. The lifetime and one year prevalences of schizophrenia and other psychotic disorders were 78.5% (male 75.3%, female 83.7%), and 56.8% (male 51.9%, female 64.8%), respectively. The lifetime and one year prevalences of alcohol use disorder (dependence/abuse) were 26.7% (male 37.9%, female 8.3%), and 8.7% (male 12.8%, female 2.1%), respectively. The lifetime and one year prevalences of mood disorder were 18.1% (male 13.5%, female 25.8%), and 10.4% (male 7.2%,female 16.9%), respectively. The lifetime and one year prevalences of schizophrenia and other psychotic disorders were comparable with the 2001 community survey by 1.19% to 1.32%, and 0.51% to 0.61%, respectively. The lifetime and one year prevalences of schizophrenia were also comparable by 0.16% to 0.28%, and 0.16% to 0.25%, respectively. There were no significant changes of prevalence rates when correction were applied to other psychiatric diagnosis. Conclusion : The results of this study could be used for evaluating the distribution of psychiatric diagnoses in mental health related facilities and for planning mental health policies.

조맹제,함봉진,서동우,홍진표,배재남,김장규,이동우,조성진 大韓神經精神醫學會 2002 신경정신의학 Vol.41 No.1

연구목적 : 본 연구는 국제적인 정신장애 진단도구인 Composite International Diagnostic Interview(CIDI)를 한국의 사회문화적 상황에 적합하게 번역하고 신뢰도 및 타당도를 평가하여 한국어판으로 개발하기 위한 것이다. 방 법 : CIDI는 정신장애를 평가하고 진단할 수 있는 포괄적이고, 완전히 표준화된 진단도구로 훈련받은 일반인들이 적용할 수 있기 때문에 대규모 역학조사에 적합하다. 세계보건기구에서 제공하는 CIDI 번역 지침에 따라 한국어판 CIDI(K-CIDI)를 제작하였다. 영어권과 한국의 언어 및 사회문화적 차이를 고려하여 번역 및 개정을 하였고 역번역을 통하여 원본의 의미와 일치하는지를 확인하였다. 임상환자를 135명과 일반인 5명을 대상으로 신뢰도와 타당도 검사를 실시하였다. 두 명의 평가자가 K-CIDI를 이용하여 동일한 대상자를 동시에 면담하고 일주일 뒤에 재검사를 실시하였다. K-CIDI로 검사를 받은 대상자들을 정신과 전공의와 임상심리사가 한국어판 Structured Clinical Interview for DSM-Ⅳ를 이용하여 진단을 내렸다. 두 가지 진단의 일치도에 대한 kappa값을 산출하였다. 결 과 : CIDI의 번역에서 한국어 표현이 복잡하고 긴 문항은 두 개의 문장으로 분리하였고, 성과 관련된 표현과 의료체계 및 의료추구행태에서 사회문화적 차이를 반영하였다. 공포장애의 대상과 알코올 및 물질의 종류도 한국의 실정에 맞게 조정하였다. 현장 검사와 역번역 과정에서 K-CIDI가 적절하게 제작된 것으로 평가되었다. K-CIDI의 평가자간 신뢰도 검사는 140명에 대하여 이루어졌고 kappa값은 진단에 따라 0.86∼1.00범위였다. 검사/재검사 신뢰도 검사는 47명에 대해 이루어졌고 kappa값은 진단에 따라 0.42∼0.89였다. K-CIDI의 타당도 검사는 50명에 대해 이루어졌고 kappa값이 진단에 따라 0.50∼1.00의 범위였다. 결 론 : K-CIDI는 한국의 사회 문화적 배경에 적합하게 제작되었고 신뢰도 및 타당도 검사에서 역학연구에 적절한 진단도구로 평가되었다. Objectives : This study aims to develop a Korean version of the Composite International Diagnostic Interview(K-CIDI). Methods : The Composite International Diagnostic Interview(CIDI) is a comprehensive, fully standardized interview that can be used to assess psychiatric disorders and provide diagnoses. The K-CIDI was developed according to the guidelines provided by the WHO. The reliability and validity of the K-CIDI was evaluated by examining 135 psychiatric patients and five community residents. Subjects were jointly interviewed twice with a one-week interval. A psychiatric resident and clinical psychologist jointly determined clinical diagnoses using the Structured Clinical Interview for DSM-Ⅳ. Results : Notable modifications were done on sex-related expression, health system and help seeking behavior, subjects for phobic disorder, and kinds of alcohol and substance. Long and complex questions were divided into two or more questions. Field test and back-translation of the K-CIDI confirmed the appropriateness of the translation of the CIDI. The inter-rater reliability, test/retest reliability, and validity of the K-CIDI indicated kappa values ranging from 0.86-1.00, 0.42-0.89, and 0.50-1.00, respectively. Conclusion : The K-CIDI was deemed to be appropriate for the sociocultural background of Koreans. The reliability and validity of the K-CIDI were judged to be exceptionally acceptable.

노사학파 심포(心圃) 문형(文炯)의 학술 관계망

조우진 ( Cho Woo-jin ) 전남대학교 호남학연구원 2023 호남학 Vol.- No.74

본 논문은 노사학파 재전문인 심포(心圃) 문형(文炯)의 학술 관계망을 살펴보는 데 목적이 있다. 문형은 전남 화순 청풍면 출신으로 개항기와 일제강점기를 걸쳐 살았던 성리학자이다. 어려서는 민우식(閔佑植)에게 13년 동안 유학을 배웠으며, 민우식이 죽기 직전 정의림(鄭義林)을 찾아가 9년 동안 기정진(奇正鎭)의 이론을 수학하였다. 정의림이 죽자, 『노사집(蘆沙集)』을 스승으로 삼아 노사학의 정수를 확인하였다. 문형은 영ㆍ호남의 노사학파와 화서학파의 재전문인 뿐만 아니라 영남의 한주 학파의 재전문인 및 당대 최고의 문장가 등과 교류를 확대하면서 학문적 유대와 사상적 통합을 이루고자 했다. 이것이 바로 지역과 사상을 횡단하는 문형의 학술 관계망의 특징이다. 특히 문형은 자신의 호를 ‘심포(心圃)’라고 했던 것처럼 성리학의 핵심 개념인 심(心)을 바탕으로 자신의 철학 체계를 완성하였다. 그는 화서학파 김평묵(金平默) ㆍ최익현(崔益鉉)의 문인들과 교유하면서 이항로(李恒老)의 심주리(心主理)에 대한 견해를 적극적으로 옹호하였으며, 한주학파 곽종석(郭鍾錫)의 문인들과 소통하면서 이진상(李震相)의 심즉리(心卽理)를 비판적으로 수용하였다. 더불어 문형은 리(理) 중심의 사유체계를 바탕으로 <성사심제변(性師心弟辨)>을 지어 간재(艮齋) 전우(田愚)가 심을 주기적(主氣的) 입장으로 보는 병폐를 지적하였다. 문형의 위상은 다양한 학파와 심을 중심으로 한 학술 관계망을 형성하여 당시의 성리학적 문제의식을 통합하고자 했다는 점이고, 그의 역할은 화순 노사 학맥을 이어 확산을 주도했을 뿐만 아니라, 화순 노사학파의 중심에 서 있었다는 점이다. 문형은 정주학을 토대로 노사학을 전수하여 화순 근현대 유학을 정립하는 데 중추적인 역할을 하였으며, 미래지향적 지역학으로써 화순학(和順學)을 수립할 수 있는 학술적 기반을 제공하였다. This paper aims to explore the academic network of Shimpo[心圃] MunHyeong(文炯, 1882-1936), a redeliver disciple[再傳門人] of Nosa School[蘆沙學派]. MunHyeong is a Neo-Confucian scholar who was born in Cheongpung-myeon[淸風面], Hwasun, Jeollanam-do, and lived during the opening period and Japanese colonial era. When young, he learned to study Neo-Confucianism from MinWoosik[閔佑植] for 13 years, and just before Min Woo-sik died, he visited JungEuirim[鄭義林] and studied KiJeongjin[奇正鎭]’s theory for 9 years. When JungEuirim died, he confirmed the essence of Nosahak[蘆沙學] regarding 『Nosajip[蘆沙集]』 as his teacher. MunHyeong sought to achieve academic ties and ideological integration by expanding exchanges with not only redeliver disciples[再傳門人] of Nosa School[蘆沙學派] and Hwaseo School[華西學派] in YeongnamㆍHonam but also redeliver disciples[再傳門人] of the Hanju School[寒洲學派] and Good writers[文章家] of the time. This is the characteristic of academic network of MunHyeong that crosses regions and ideas. In particular, MunHyeong completed his philosophical system based on the core concept Shim[心] of Neo-Confucianism, as he called his pen name ‘Shimpo’. He actively advocated IHanglao [李恒老]’s view of Shimjuli[心主理] while interacting with the writers of the Hwaseo School of KimPyeongmuk[金平默] and ChoeIckhyun[崔益鉉], and critically accepted IJinsang[李震相]’s Shimjeukli[心卽理] while communicating with the writers of KwakJongseok[郭鍾錫] of the Hanju School. In addition, Moon Hyung wrote < Seongsashimjebyeon[性師心弟辨] > based on the Li[理]-centered thinking system and pointed out the problem of Ganje[艮齋] JeonWoo[田愚]'s view of Shim[心] as Jugi[主氣] position. MunHyeong's status was to form an academic network centered on various schools and Shim and to integrate the Neo-Confucian problem consciousness of the time, and his role was not only to lead the spread of Hwasun Nosahakmaek, but also to be at the center of Hwasun Nosa School. MunHyeong played a pivotal role in establishing modern and contemporary Hwasun Confucianism by transferring Nosahak based on ChéngZhūxué[程朱學], and provided an academic foundation for establishing Hwasunhak[和順學] as a future-oriented regional studies.

한오수,안준호,송선희,조맹제,김장규,배재남,조성진,정범수,서동우,함봉진,이동우,박종익,홍진표 대한신경정신의학회 2000 신경정신의학 Vol.39 No.2

연구목적: 정신장애의 정확한 진단과 평가는 임상에서뿐만 아니라 신뢰성 있는 연구를 위해서도 매우 중요하다. Structured Clinical Interview for DSM-IV(SCID)는 임상전문가들이 사용하는 진단도구로서, 비교적 짧은 시간에 정확한 진단을 내릴 수 있다. 본 연구는 한국어판SCID를 개발하고 그 신뢰도를 평가하기 위해 수행되었다. 방법: 국문학자가 포함된 번역위원회를 통하여 연구용판 SCID를 번역한 후, 정신과 의사 2인과 임상심리학자 1인에게 한국어판SCID 실시방법을 교육시킨 뒤 한국어판SCID를 이용한 면담의 평가자간 신뢰도 (interrater reliability)를 검증하였다. 면담 대상은 1999년 2월에서 3월까지 2개 병원 정신과에 치료중인 환자 90명(남:41명, 여:29명)이었다. 결과: 현재 장애(current disorder) 평가에서 주요 우울장애, 기분부전장애, 정신분열병, 알코올 남용 및 의존, 기타 물질 남용 또는 의존, 여러 불안장애들 및 섭식장애 등과 같은 대부분 장애의 kappa값은 .70이상으로 매우 높았다. 그 이외의 양극성 장애, 망상장애, 광장공포증, 감별 불능 신체화 장애 및 건강염려증의 kappa값도 .69에서 .40사이로 수용할 수 있는 정도였다. 평생 장애(lifetime disorder)에서는 양극성 장애(k=.69)와 감별 불능 신체화장애(k=.59)를 제외한 다른 모든 장애의 kappa값이 .70이상이었다. K-SCID 면담시 Ⅰ축 질환에 대하여 흔하게 다중 진단이 내려졌으며, 평균 진단 수는 1.5∼1.7개로 나타났다. 결론: 한국어판 SCID는 신뢰도가 높은 진단도구로 생각되며, 향후 정신질환의 정확한 진단과 임상연구에 유용하게 사용될 수 있다. Objectives: Accurate diagnosis and assessment for psychiatric disorders is crucial for research, as well as for clinical practice. Structured Clinical Interview for DSM-Ⅳ(SCID-RV) is a less time-consumimg and more accurate structured diagnostic interview form. It can be used by clinical professions and is known for a reliable diagnostic tool. Present study was conducted to develop Korean version of SCID-RV and to test the inter-rater reliability. Methods: The authors have translated original SCID-RV into Korean, and revised in parallel with sociocultural background of Korea. Ninety patients from two psychiatric hospitals, both outpatient and inpatient, were interviewed and rated independently by three raters. Results: The kappa coefficients for most of illnesses, such as major depressive disorder, dysthymia, schizophrenia, alcohol abuse and dependency, anxiety disorder and eating disorder were excellent(>0.70) in the evaluation of current disorders. And the kappa coefficients for bipolar disorder, delusional disorder, agoraphobia, undifferentiated somatoform disorder, and hypochondriasis were acceptable(>0.40) in the evaluation of current disorders. In the evalua-tion of lifetime disorders, the concordant rates of all the diagnoses except bipolar disorder and undifferentiated somatoform disorder were excellent. Lack of hierarchy in DSM-Ⅳ allows for multiple Axis I diagnoses. Mean numbers of Axis I diagnoses per subject assigned by the three raters were 1.5-1.7. Conclusions: Our findings confirm that SCID-RV yields highly reliable diagnoses. SCID-RV is recommended for accurate diagnosis in clinical practice and research on psychiatric disorders.

Ⅱ급 부정교합자에서 액티베이터 사용에 따른 atlas의 위치 변화에 관한 연구

조문기,이진우,차경석,정동화 대한치과교정학회 2007 대한치과교정학회지 Vol.37 No.1

본 연구는 Ⅱ급 부정교합자에서 액티베이터 사용 후, 하악골의 변화에 따른 atlas의 위치 및 형태 변화를 조사하고, 그에 따른 치료 효과를 예측해 보고자 시행하였다. 실험군으로 Ⅱ급 부정교합자로써 액티베이터 치료를 시행한 경우 1군(총30명, 남자 15, 여자 15명), 대조군들로 Ⅱ급 부정교합자로 액티베이터 치료를 받지 않고, 교정치료를 받은 2군(총 22명, 남자 12, 여자 10)과 Ⅰ급 부정교합자로 치료를 받은 환자 3군(총 22명, 남자 12, 여자 10)으로 총 세 개의 군으로 나누었다. 치료 전(T1), 액티베이터 사용 중지 및 치료 중간시기(T2), 치료 종료(T3)시의 측모두부방사선사진을 통해서 골격 형태 계측 및 atlas 형태 계측을 시행하였다. Ⅱ급 액티베이터 사용 결과 액티베이터를 사용하지 않은 Ⅱ급 부정교합자 군에 비해 치료 종료 시 다음과 같은 계측치 들에서 골격적인 효과가 나타났다: ramal height, body length와 effective body length는 증가하였고, ANB는 감소하였다. Overjet은 두 군 사이에서 액티베이터 사용 후 유의한 감소가 일어났으나, 치료 종료 시에는 유의한 변화가 없었다. 세 군 모두에서 FH에 대한 atlas의 시계방향 회전이 나타났으나, 실험군 1군에서 대조군 2, 3군에 비해 유의하게 atlas가 FH에 대해 시계방향 회전되는 결과가 나타났다. 1군이 3군에 비해서 atlas의 유의한 후방이동을 보인 것을 제외하고는 세 군 사이의 atlas의 전, 후방적 위치나, 형태의 크기 변화에 있어 유의한 차이점은 없었다. 위의 결과들을 고려해 볼 때 atlas의 장축의 시계방향 회전은 액티베이터의 사용 효과로 생각되며, 이는 차후 Ⅱ급 부정교합자에서 액티베이터 치료 효과를 판단하는 또 하나의 지표가 될 수 있다고 생각한다. Objective: Previous studies have reported that morphological features of the first cervical vertebra(atlas) have been associated with mandibular growth direction. The purpose of this study was to show the possible positional and morphological changes of the Atlas from activator treatment in Class Ⅱ malocclusion patients. Methods: Lateral cephalometric radiograph tracings were made at initial, middle and final stages of treatment. Angular and linear measurements of skeletal and morphological features were measured on the anatomical landmarks and reference planes. Results: The skeletal effects of activator treatment on Class Ⅱ malocclusion patients were evident on ramal height, body length, effective body length, ANB, and overjet. Clockwise rotation of the long axis of the Atlas was found in Group 1, but there was no inclination change of the Atlas in groups 2 and 3. There was no significant correlation between anterior and posterior positions of the atlas or morphological change in all groups. - except for posterior movements of the Atlas found in group 1. Conclusion: Clockwise rotation of the atlas axis resulted from activator treatment in CI Ⅱ malocclusion patients. Change in atlas axis can be thought of as an indicator for success of activator treatment.

조진숙,황윤찬,김선호,황인남,최보영,정영진,정우남,오원만 전남대학교 치의학연구소 2003 구강과학 Vol.15 No.4

This study was performed to confirm the actual temperature rise on the surface of Buchanan plugger by evaluating the temperature rise on the surface of it, the peak temperature of pluggers of various size using thermocouple. The heat carrier system 'System B Heatsource' (Model 1005, Analytic Technologies, USA) and the Buchanan pluggers of F, FM, M and ML sizes are used for this study. The temperature was set to 200 which Dr. Buchanan's "Continuous wave of condensation" technique recommended on digital display and the power level on it was set to 10. The touch mode was used. Five thermocouples were placed in direct contact with the surface of each size of Buchanan's pluggers at 1 ㎜ increments from the tip to the 4 ㎜ length of shank. Each thermocouple was secured with cyanoacrylate adhesive and orthodontic resin block. The two wire leads of each thermocouple were connected to the appropriate channels of Data Logger. This was configured to simultaneously record input from the five thermocouples. The heat control spring was touched for 1, 2, 3, 4 and 5 seconds, and the temperature rise on the surface of the pluggers were measured at 1 sec intervals for more than 5 seconds with an accuracy of 0.01. Ten trials was determined for each plugger. The average of temperature rise and standard deviation was calculated for each size of plugger. The data were statistically analyzed by one-way ANOVA to determine their significance. The results as follows. 1. The position at which the temperature peaked was approximately at 1∼2㎜ far from the tip of Buchanan plugger (p<0.01). 2. The peak temperature was 215.25±2.28℃ in F plugger, 185.94±2.19℃ in FM plugger, 169.51±9.12℃ in M plugger, and 160.79±1.27℃ in ML plugger and the peak temperature was highest in F type and followed by, in descending order, FM type, M type. ML type showed the lowest peak temperature (p<0.01). This results suggest that the actual temperature on the surface of the pluggers does not correlate well with the temperature set on digital display. Heat concentrates around the tip. The larger plugger reveals lower temperature rise relatively.

조영태,이진우,양동양 대한건축학회 2003 대한건축학회논문집 Vol.19 No.4

Despite a hundred year long history of the planning and construction of modern courthouse in Korea, the adequate evaluations thereof are overdue. This study aimed to prevent uniformity in courthouse designs and to suggest desirable direction of planning for the public-use, through the investigation of the domestic(including Seoul District Court Complex) and 27 foreign instances. Architectural factors were analyzed in 1)site plans and outdoor space, 2)external appearance, 3)internal space program, 4)circulations. Especially, internal space program of floor with courtrooms and circulations of users are important analysing factors in this paper. As the result of this study, most of domestic courthouses are very much similar in site planning, massing, appearance, and judge oriented circulation plans. These characteristics of planning are purposed to express the equity and dignity of law. But the instances of European and USA have various type of spatial composition and the general public-oriented planning.

조미영,손상규,김이청,김진우,오명주,정성주,박수일 한국어병학회 2003 한국어병학회지 Vol.16 No.3

양식 잉어류에서 심각한 피해를 야기하고 있는 VSNCV에 대한 백신을 제작하며 잉어에 투여한 후 특이적 및 비특이적 면역반응을 조사하였다. 백신은 포르마린처리백신 (FKV)과 가온처리백신 (HKV)를 제작하여 건강한 잉어에 0.2㎖씩 복강주사 하였으며, 2주 후 동일한 방법으로 boost처리하였다. 백신 투여 후 비특이적 면역반응 중 혈청 라이소자인 활성과 대식세포의 chemiluminescent (CL) reponses은 1차 주사 후 및 boost 처리 후 2일째부터 7일째까지 유의적인 증가를 나타내었으며, 이후 대조구 수준으로 감소하였다. ELISA법으로 항체가를 조사한 결과 대조구를 제외한 FKV와 HKV 투여구에서 주사 후 2주 째부터 boost처리 후 6주 째까지 유의적으로 증가하였으며, 그 중에서도 boost 처리 후 2주 째에 VSNCV로 공격 실험한 결과 FKV 투여구에서는 20%의 누적폐사율을 나타내어 방어력이 인정 되었으나, HKV투여구에서는 70%의 누적폐사율이 나타나 방어효과가 거의 없는 것으로 나타났다. VSNC is a viral disease causing significant economic losses in cultured carp Ciprinus carpio L. in Korea. Carps were immunized with prepared vaccines against VSNCV and examined specific and nonspecific immune responses. Carps were injected by 0.2㎖ of formalin-killed vaccine(FKV), heat-killed vaccine(HKV) or E-MEM, respectively and dealt with boost with same way two weeks later. The lysozyme activity of serum and chemiluminescent reponses of head-kidney leucocytes showed increased responses during 2-7 days post-first injection(pfi) and post-boost(pb) in the vaccinated fish, and then decreased to the level of control. As measured by ELISA, vaccinated groups showed a significant increase in VSNCV-specific serum antibodies between 2 weeks pfi and 6 weeks pb with a peak at 2 weeks pb. Results of the virus challenge showed that the fish vaccinated with FKV have induced protective immunity, white HKV injection hardly provided protection.

조규현,김제섭,전판근,백민수,김우재,정상진 대한건축학회 2004 대한건축학회 학술발표대회 논문집 - 계획계/구조계 Vol.24 No.1(구조계)

The present study is a basic experiment on the estimation of the compressive strength of high strength concrete, aiming at estimating the compression strength of mass test pieces of high strength concrete by giving the temperature hysteresis of the mass test pieces to managerial test pieces. Different from ordinary concrete, high strength concrete generally shows the high rise of temperature caused by hydration heat inside the concrete. It is known that, in mass concrete, thermal stress occurs due to the difference in temperature between the inside and the outside, which causes a significant difference in compression strength between structure beams and managerial test pieces. It is also reported that there is a large difference between the compression strength of cylindrical managerial test pieces of standard underwater curing and the strength of structure beam concrete. Thus, this study made concrete test pieces in an optimal mix ratio for each strength level, and also created adiabatic curing tank and managerial test pieces. Then it carried out comparative analysis in relation to core strength and suggested equipment and a technique that can control the strength of high strength concrete mass more conveniently and accurately.
