심미적으로 중요한 전치부에서 단일 치아 임플란트를 이용한 보철수복은 임상의에게 새로운 도전과제 중의 하나가 되었다. 그러나 전치부에서 single-unit implant는 식립할 부위의 치조골 상태가 양호해야 하는데 치은연하 파절로 인해 치아 주위에 골 손실이 있는 경우 immediate implant는 심미적으로 문제를 야기할 수 있다. 따라서 본 증례는 "orthodontic extrusive remodeling"을 통해 파절치와 주위 조직을 교정적으로 정출시켜 임플란트 식립을 위한 연조직과 경조직을 증대시킨 후 임플란트 식립을 통해 상악측절치에서 성공적인 심미수복을 이룬 증례에 관한 것이다. The treatment of esthetic areas with single-tooth implants represents a new challenge for the clinician. In 1993, a modification of the forced eruption technique, called "orthodontic extrusive remodelling" was proposed as a way to augment both soft- and hard-tissue profiles at potential implant sites. This case report describes augmentation of the coronal soft and hard tissues around a fractured maxillary lateral incisor associated with alveolar bone loss, which was achieved by forced orthodontic extrusion before implant placement. Through these procedures we could reconstruct esthetics and function in a hopeless tooth diagnosed with subgingival root fracture by trauma.

A complete computerized system for the characterization and performance testing of photovoltaics(PV) modules under natural sunlight and ambient condition was designed. I-V characteristics of PV module provides on essential diagnostic means in assessing the performance and internal cell parameters of PV module depends on its basic materials, manufacturing technology and operating environmental conditions. I-V curves derived from PV modules refect to a large extent the physical properties and their expected performance. In this paper, Electrical performance measurement and evaluation methods for solar cell module by MOSFET variable Load were studied. Also, Mathematical model and theory of solar cell associated with the photovoltaic effect has been discribed.

Objectives Theory of mind (ToM) is the ability to conceptualize other people's mental states in order to explain their behavior. This study compared the ToM ability of schizophrenia patients, their first-degree biological relatives, and healthy controls. Methods ToM animation test was administered to schizophrenia patients (N=28), their healthy first-degree relatives (N=26), and healthy controls (N=28). The Korean version of schizotypal personality questionnaire (SPQ) was used to assess the schizotypal personality trait of all three groups. Results Schizophrenia patients and their first-degree relatives showed decreased accuracy on ToM animation test compared to healthy controls [F(2,78)=29.75, p<.001]. Additionally, first-degree relatives performed worse than the control group and better than schizophrenia patients. First-de-gree relatives had similar SPQ scores compared to healthy controls but showed decreased ToM accuracy compared to healthy controls. Conclusion ToM deficits in schizophrenia patients are apparent. The ToM deficit in first-degree relatives of schizophrenia patients raises the possibility that ToM deficit may be a endophenotype for schizophrenia pathology.

연구목적: 만성 요통 환자의 많은 수가 직업 등 주변 환경과 심리 상태의 영향을 받는 것으로 추정되나 그 연관성은 아직 논란이 많다. 본 연구에서는 설문 조사를 통하여 만성 요통 환자의 심리사회적 특성을 알아보고자 하였다. 대상 및 방법. 1997년 7월부터 1998년 12월까지 6주 이상 지속된 만성 요통으로 본원 정형외과 외래를 내원한 환자들 중 기질적 원인이 불명확한 62명의 환자들에서 직업, 유발요인, 치료 등 요통 관련 요소 설문과 Minnesota Multiphasic Personal Inventory (MMPI)를 실시하였다. 요통 관련 사항에는 통증의 기간, 정도, 통증이 유발 또는 심해지는 자세, 그리고 본인이 생각하는 요통의 원인 등을 포함하였다. MMPI는 전체 평균을 이용한 방법과 two-code 방법을 이용하여 평가하였다. 결과: 만성 요통환자의 직업 상 실내에서 앉아 일하는 직업이 가장 맡았으며 일정한 자세를 오래 유지하며 앉거나 서 있는 경우 증상이 악화되는 것으로 기술되었다. MMPI에서는 건강 염려증, 우울증, 히스테리의 세 척도의 평균이 55이상으로 상승되어 있었다. Two-code 방법에서는 92% (46/50)의 환자에서 위 세 척도 중 적어도 하나 이상 상승되어 있었다. 결론: 만성 요통 환자들에서 일상 생활의 자세와 직업이 요통의 발생 및 악화에 영향이 있을 것으로 보여졌다. MMPI를 통한 심리 인성 검사 상 건강 염려증, 우울증, 히스테리의 성향이 증가되어 있어 요통의 발생과 만성화에 심리적 요소가 영향을 미치는 것으로 보여졌다. 사회경제학적, 정신심리학적 요인이 만성 요통에 미치는 영향의 규명을 위한 다양하고 심도 있는 연구가 필요하다고 생각된다. Purpose : Socioeconomic and psychologic factors seem to affect incidence, severity, and chronicity of low back pain. Purpose of this study is to survey socioeconomic factors and document psychoneurotic traits via MMPI in chronic low back pain patients. Materials and Methods : From July 1997 to December 1998, questionnaire about low back pain-related factors such as duration, severity, posture, occupation etc. and MMPI were given to patients who visited our department for chronic low back pain()6weeks). 62 patients completed, and 50 of them completed MMPI. The answers were analyzed. MMPI scores were evaluated in mean±SD method and two-code method. Results : Sedentary workers were the most common. And symptoms were told to be elicited by long sitting or standing posture(job) . Hs, D, Hy scales of MMPI, which are know as "neurotic triad by two-code method was observed in 92% (46/50) . Conclusion : It seemed that job and posture had Important role in chronic low back pain. And, it seemed that chronic low back pain patients had some psychoneurotic traits especially in hypochondriasis, depression, and hysteria. More investigations to document the influences of socioeconomic and psychoneurotic factors in chronic low back pain seems to be necessary.

Purpose: Our previous studies suggested that p53-positive triple-negative breast cancer (TNBC) should be more sensitive to chemotherapy than p53-negative TNBC. The aim of this study was to determine whether p53 expression in TNBC could predict response to neoadjuvant chemotherapy and the resulting prognosis. Methods: From January 2009 to December 2017, TNBC patients who underwent neoadjuvant chemotherapy were reviewed, including a total of 31 TNBC patients who had clinical lymph node metastasis. The status of p53 expression in patients before and after chemotherapy was evaluated. Results: Two patients (22.2%, 2 of 9) achieved pCR in p53(+) TNBC and 4 patients (50%, 5 of 10) achieved pCR in p53(-) TNBC. There was no correlation between pCR rate and p53 expression (P = 0.350). Based on prechemotherapy p53 expression, there was no significant difference in disease-free survival (DFS) between p53(+) TNBC and p53(-) TNBC (P = 0.335). However, after chemotherapy, p53(+) TNBC had shown higher DFS than p53(-) TBNC (P = 0.099). Based on prechemotherapy p53 expression, p53(+) TNBC had better overall survival (OS) than p53(-) TNBC, but the difference was not statistically significant (P = 0.082). After chemotherapy, p53(+) TNBC showed significantly better OS than p53(-) TNBC (P = 0.018). Conclusion: Immunohistochemically detected p53 expression in TNBC could not predict the response to neoadjuvant chemotherapy. However, p53(+) TNBC had a better OS than p53(-) TNBC in patients who underwent neoadjuvant chemotherapy.
