        Purpose : The purpose of this study is to evaluate the usefulness of arthroscopic lateral release in the management of chondromalacia patellae. Materials and Methods : The subjects were 48 patients ranging from 36 to 61 years of age. All patients were diagnosed to have chondromalacia patellae by physical examination. Arthroscopic lateral retinacular release of the knee has been performed on the patients under supine position. The results were reviewed at one year and three years after operation. Results : Of those who had grade I chondromalacia, 83.3% had a good at one year and by three years 75% were still good. Although grade III had 63.6%, the number of good results dropped to 36% by three years. Conclusion : Arthroscopy lateral retinacular release is effective for a correct classification of cartilaginous lesions, and it has a useful role to play in the management of early stage chondromalacia patellae.

      • 안정화제 처리된 회수수를 사용한 콘크리트의 특성에 관한 실험적 연구

        박영신,박재명,이세현,이문환 대한건축학회 2004 대한건축학회 학술발표대회 논문집 - 계획계/구조계 Vol.24 No.1(구조계)

        Recently, Most enterprises produced ready mixed concrete uses a mixing water as a recycling water without a density control in proportion to guide and standard. That is a cause of deterioration in the concrete quality like a reduce of strength, laitance, crack, etc. This study shows basic materials for development of ready mixed concrete recycling water density control system that holds down a deterioration in the concrete quality by using a mixed water treated recycling water with stabilizing agent and examines a possibility of re-using components of cement in recycling water. Therefore, in the experiment, we make a recycling water contains 3,5,7% of solid content ratio examines a property of a mixing water with a stabilizing agent and without it. Results of this study is next as follow. 1. The slump is decreased 1~2cm in a mixing without a stabilizing agent and the mixing with a stabilizing agent is similar to the standard mixing. 2. The air content is 4~4.7% in proportion to an increase of solid content without a stabilizing agent and the mixing with a stabilizing agent is similar to the standard mixing. 3. The compressive strength of an early curing age is tendency to increase both the mixing without a stabilizing agent and the mixing with a stabilizing agent. But, After 14days is passed, Compressive strength is decreased in a mixing without a stabilizing agent but increased a mixing with a stabilizing agent.

        성인간호학회지 논문(1989-2000)의 내용과 경향 분석

        서문자,김소선,송미순,이명선,오의금,신경림,김옥수,이숙자,이영자,오효숙,정재심,김철규 성인간호학회 2001 성인간호학회지 Vol.13 No.4

        "Journal of Korean Academy of Adult Nursing" has been published since 1989 and more than 330 articles have been published up 2000. We reviewed all the articles published in this journal to analyze the contents and trend of published articles and to find out the way of improvement both in quantity and quality of studies in this area. The results are as follows : 1) Ninety percent of articles were quantitative studies. Experimental design was used in 16.1% and quasi-experimental design was adapted in 73.6% of articles. Qualitative research were 10.3% of total articles reviewed. 2) Only 5.1% of articles described theoretical framework and 73.6% of experimentally designed articles included research hypotheses. 3) Among experimental studies, only one was true experimental studie design. Eighty nine point three persent had descriptive survey method among non-experimental studies. Amog the thirty four qualitative studies, phenomenologic(73.5%), grounded theory(14.7%), and ethnographic (11.8%) design were used. 4) Most of research subject were patients and few healthy people, healthcare worker, and patient family. 5) Psychosocial data collection method which used questionnaire were 53.7% and interview. physical measurement, observation were used in 22.8%. 8.2% 5.4% of articles respectively. 6) Total number of keywords were 692, and average number of key words per article was 2.2. Health-related keyword was the most frequently used according to four metaparadigm of nursing (human, health, nursing, and environment). Environment related keyword was rarely appeared. The number and quality of nursing research in "Journal of Korean Academy of Adult Nursing" have been improved continuously. It is difficult to find out special trend or characteristics which is unique in this journal because of relatively short history of adult nursing studies. This review study was performed to analyze adult nursing studies only in the view of quantitative aspect, but it is needed to analyse qualitatively to find philosophical or theoretical trend in nursing.

        Objective The purpose of this study was to examine the regional cerebral blood-flow (CBF) difference between boys with pure ACHD and normal controls before and after methylphenidate treatment, and also we examined the association between rCBF changes and cognitive characteristics of boys with pure ADHD before and after methylphenidate treatment. Methods The rCBF of 5 boys with pure AOHD and 5 control boys were examined by Tc-99m ECD brain SFECT and cognitive characteristics by ADS and every 5 ADHD boys took MPH for 12 to 16 weeks After that all ADHD boys took Tc-99m ECD brain SPECT and checked ADS again rCBF difference and changes before and after MPH treatment were quantified and analyzed by using SPM And associations between types of cognitive changes measured by ADS and rCBF changes were examined and quantitative associations between them were also analyzed by using Pearson's coefficient correlation. Results 1) Before MPH treatment, rCBF of ADHD boys were significantly decreased in left orbitofrontal area and left caudate nucleus compared to normal controls 2) After MPH treatment. rCBF of the same regions were significantly increased. 3) There was positive correlation between the degree of commission error(impulsivity disinhibition) among the ADS variables and the degree of blood-flow decrease in above two areas before MPH treatment but after MPH treatment, only with the degree of rC3F increase in Lt orbitofrontal area. Conclusion : These results suggest that the pathophysiology of impulsivity of disinhibition of the characteristic symploms of AOHD boys IS associated with hypoactivties of left orbibfrontal area and left caudate nucleus, and MPH pharmacodynamics in ADHD boys is associated to their actions on these two areas.

        접착제와 와동형성의 차이에 따른 5급 복합레진 수복의 전향적 임상연구

        이경욱,정세준,한영철,손호현,엄정문,오명환,조병훈 大韓齒科保存學會 2006 Restorative Dentistry & Endodontics Vol.31 No.4

        본 연구의 목적은 복합레진을 이용한 비우식성 치경부 5급 병소 수복에 있어서, 3가지 다른 접착제를, 유지구를 부여한 치아와 부여하지 않은 치아에 적용하였을 때의 임상적인 효능의 차이를 비교하기 위함이다. 총 150개의 치아를 각각 25개씩 6개의 군으로 나누었다. A군 Scotchbond Multi-Purpose (SBMP, 3M ESPE, St, Paul, MN, USA, 4세대 접착제)를 사용하고 유지구를 부여하지 않음. B군: SBMP를 사용하고 유지구를 부여. C군: BC Plus (Vericom Co., Anyang, Gyeonggido, Korea, 5세대 접착제)를 사용하고 유지구를 부여하지 않음. D군: BC Plus를 사용하고 유지구를 부여. E군: Adper Prompt (3M ESPE, Seefeld, Germany, 6세대 접착제)를 사용하고 유지구를 부여하지 않음. F군: Adper Prompt를 사용하고 유지구를 부여. 모든 치아는 복합레진인 Denfil(Vericom Co., Anyang. Gyonggido. Korea)을 이용하여 충전하였다. 수복 직후와, 수복 6개월 후에 modified USPHS (United States Public Health Service) criteria에 따라 수복물을 임상적으로 평가하였다. 추가적으로 임상사진을 촬영하였으며, 에폭시 레진을 이용하여 복제한 후 주사전자현미경을 이용하여 이를 관찰하였다. 6개월 후 관찰 결과. alpha rating의 수가 각 실험군마다 동일하지는 않았지만, 통계적으로는 3가지의 접착제간에 유의할만한 차이는 없었고, 기계적인 유지구를 부여한 군과 부여하지 않은 군 간에도 유의할만한 차이는 없었다 (p > 0.05). 그러나 6개월의 관찰 기간은 일반적으로 기대되는 레진의 수명보다 짧기 때문에, 각 실험군 간의 차이를 알아보기 위해서는 추후 더 오랜 기간의 관찰이 요구된다. The purpose of this study is to evaluate prospectively the effect of different bonding systems and retention grooves on the clinical performance of resin restorations in non-carious cervical lesions (NCCLs). Thirty nine healthy adults who had at least 2 NCCLs in their promolar areas were included in this study. One hundred and fifty teeth were equally assigned to six groups; (A) Scotchbond Multi-Purpose (SBMP, 3M ESPE, St, Paul, MN, USA, 4th generation bonding system) without retention grooves; (B) SBMP with retention grooves: (C) BC Plus (Vericom Co., Anyang, Gyeonggido, Korea, 5th generation bonding system) without retention grooves; (D) BC Plus with retention grooves; (E) Adper Prompt (3M ESPE, Seefeld, Germany, 6th generation bonding system) without retention grooves: (F) Adper Prompt with retention grooves. All cavities were filled with a hybrid composite resin, Denfil (Vericom Co., Anyang, Gyeonggido, korea) by one operator. Restorations were evaluated at baseline and at 6-month recall, according to the modified USPHS (United states Public Health Service) criteria, Additionally, clinical photographs were taken and epoxy resin replicas were made for SEM evaluation. At 6-month recall, there were some differences in the number of alpha ratings among the experimental groups. But, despite the differences in the number of alpah ratings, there was no significant difference among the 3 adhesive systems (p > 0.05). There was also no significant difference between the groups with or without mechanical retention (p > 0.05). Follow-ups for longer periods than 6 months are needed to verify the clinical performance of different bonding systems and retention grooves. 〔J Kor Acad Cons Dent 31(4):300-311, 2006〕
