두부제조용 콩에 오염된 총균수는 콩 g당 104~105 범위였으며, 수침시 오존을 2~4ppm 수준으로 3시간 처리한 결과 오염균의 90~98%가 제거되었다. 오존처리한 콩을 이용하여 제조된 두부를 멸균용기에 담아 20℃와 30℃에서 저장실험을 행한 결과 20℃의 경우 무처리는 30시간째부터 부패되기 시작하였으나 처리한 경우는 72시간까지 신선한 상태로 유지되었다. 그러나 30℃에 둔 경우에 무처리는 15시간만에 부패되기 시작하였으며 처리한 경우도 4~5시간 더 연장되었으나 큰 효과가 없었다. In order to improve the shelf-life of Tofu, the elimination of contaminated bacteria by ozone treatment was examined. Tofu prepared from ozone treated-soybean was investigated for microbial, physicochemical and sensory changes during storage at 20℃ and 30℃. As a result of treatment in ozonic water by 2~4ppm/sec for 3 hours, 90~98% of the total bacteria in material soybean for Tofu was eliminated. At 20℃, control Tofu was found to be spoiled after 30 hours by reaching the number of bacteria more than 10^6cells/g, Tofu prepared from ozone treated-soybean was found to be spoiled after 72 hours. Titratable acidity and sensory changes of Tofu was increased as spoilage of Tofu was progressed, but pH was decreased at the first day of storage, and after that it was increased. At 30℃, there was no remarkable difference between Tofu of control and Tofu prepared from ozone treated-soybean.

PURPOSE. To analyze the stress distribution of the implant and its supporting structures through 3D finite elements analysis for implants with different hexagon heights and to make the assessment of the mechanical stability and the effect of the elements. MATERIALS AND METHODS. Infinite elements modeling with CAD data was designed. The modeling was done as follows; an external connection type ∅4.0 mm×11.5 mm OsstemUSII (Osstem Co., Pusan, Korea) implant system was used, the implant was planted in the mandibular first molar region with appropriate prosthetic restoration, the hexagon (implant fixture’s external connection) height of 0.0, 0.7, 1.2, and 1.5 mm were applied. ABAQUS 6.4 (ABAQUS, Inc., Providence, USA) was used to calculate the stress value. The force distribution via color distribution on each experimental group’s implant fixture and titanium screw was studied based on the equivalent stress (von Mises stress). The maximum stress level of each element (crown, implant screw, implant fixture, cortical bone and cancellous bone) was compared. RESULTS. The hexagonal height of the implant with external connection had an influence on the stress distribution of the fixture, screw and upper prosthesis and the surrounding supporting bone. As the hexagon height increased, the stress was well distributed and there was a decrease in the maximum stress value. If the height of the hexagon reached over 1.2 mm, there was no significant influence on the stress distribution. CONCLUSION. For implants with external connections, a hexagon is vital for stress distribution. As the height of the hexagon increased, the more effective stress distribution was observed. 연구 목적: 본 연구는 hexagon 높이에 따른 임플란트 각 부위와 주위 지지조직의 응력분포를 3차원 유한요소 해석을 통해 평가하여 hexagon 높이가 기계적 안정성에 미치는 영향을 평가하고자 시행되었다. 연구 재료 및 방법: 외측 연결 형태의∅L4.0 mm×11.5 mm USII (Osstem Co., Pusan, Korea) 임플란트 시스템을 이용하여 하악 제 1대구치 부위에 임플란트를 식립하여 보철 수복한 경우를 연구 모델로 가정하고 임플란트 고정체의 외측 연결부인 hexagon의 높이를 각각 0.0 mm, 0.7 mm, 1.2 mm, 1.5 mm로 적용한 CAD data를 유한요소 모형화하였다. ABAQUS 6.4 (ABAQUS Inc., Providence, RI, USA)를 이용하여 산출된 응력 값 중에서 등가응력을 기준으로 각 요소(상부 치관, 지대주 나사, 고정체, 치밀골, 해면골)에서 나타나는 최대 응력 값을 비교 하였다. 결과:외측 연결을 갖는 임플란트의 hexagon의 높이는 고정체, 지대주 나사, 상부 보철물 그리고 주위 지지골에 대해 응력 분산에 영향을 주었다. Hexagon의 높이가 증가할 수록 임플란트의 응력 분산은 더 잘 이루어졌으며, 최대 응력 값의 감소를 보였다. Hexagon의 높이가 1.2 mm 이상이 되면 응력 분포에 더 이상 크게 기여하지 않았다. 결론: 외측연결을 갖는 임플란트에서 hexagon은 응력 분산에 필수적인 요소이며 그 높이가 증가할수록 더욱 효과적인 응력의 분산이 나타났다.

Purpose : The purpose of this study was to investigate relationships among family support, self-care, and quality of life of patients with arthritis through a survey. That will be basic data to plan nursing intervention for promoting quality of life for patients with arthritis. Method : The convenient sample of this study consisted of 120 patients with arthritis and data were collected using questionnaires during August 2006 from two OPDs of rheumatoid centers in C University hospitals. The study instruments were used to measure Self Care (So, 1992), Family Support (Kang, 1984), and Quality of Life (Ro, 1988). The data were analyzed using ANOVA, Duncan test, and Pearson correlation. Result : The mean scores were 3.56 for family support, 4.16 for self-care, and 3.19 for quality of life. The level of self-care was significantly higher in those men, having an occupation, higher income, and living with family members. The level of family support was significantly higher in those men, having an occupation, living with family members, and having a helper. The level of quality of life was significantly higher for those men, having a higher income, and shorter length of illness. Three relationships were found to be positively correlated: 1) between the levels of family support and self-care (r=.53), 2) between the levels of self-care and quality of life (r=.55), and 3) between the levels of family support and quality of life (r=.54). Conclusion: Therefore, a nursing intervention program needs to be developed to promote family support, and self-care for quality of life for patients with arthritis.

We investigated the effects of deep sea water of South Korean East Sea in various cells of the mammalian nervous system. Deep sea water has been collected from 1,100 m of South Korean East Sea seabed, demineralized and concentrated, and then utilized. Hardness of the deep sea water was adjusted by adding minerals at hardness 4,000. The deep sea water showed protective effects on mammalian retinal and olfactory cells under metabolic stress in hardness dependent manners. In contrast, the deep sea water could not protect the retinal cells against oxidative stress, whereas it reduced the production of reactive oxidative species in the retinal cells in the hardness dependent manner. It also showed a minute inhibitory effect on inflammatory responses. Of our interest, the deep sea water suppressed formation of β-amyloidal fibril which is one of pathological action of the Alzheimer's disease. In summary, the deep sea water exhibits various neuroprotective effects, implying its pharmaceutical use.

한국어가 2007년에 세계지식재산권기구의 국제특허협력조약의 국제공개어로 공식 채택되면서 한국어의 위상은 더욱 높아졌다. 시대의 변화와 함께 본격적인 활성화를 띤 한국어 교육 정책은 그 범위가 확대되었고, 이와 관련하여, 큰 비중을 차지하기에 더욱 관심을 가져야 하는 영역이 재외동포에 대한 한국어교육이라고 본다. 재외동포들의 한국어 능력은 세계화시대에 한국의 소중한 국가적 자산이며 가치이다. 21세기 글로벌 시대에는 인적자원 역량이 국가 경쟁력을 좌우하는 시대이기에 재외동포를 위한 한국어 보급 정책을 재조명해 보아야 할 필요성이 있다. 따라서 본 연구는 현행 재외동포를 위한 국외 한국어교육기관의 현황을 진단해 보고, 향후 추진해야 할 발전 방향에 대해서 제안한다. The status of Korean language been soared since it was selected as an official language of the International Patent Cooperation Treaty of the World Intellectual Property Organization. In relation to Korean language education, the education for overseas Koreans is given a great deal of weight and therefore should be given attention. Overseas Koreans’ Korean language skill is one of the most important national capitals and values in the age of globalization. They not only play an important role as mediators between Korean people home and abroad, but also keep and promote Korean culture and spirit in the world. In this globalized world of the 21st century, a nation’s competitiveness depends on its human resources, so the Korean language policy should be reviewed. Thus, this study diagnoses the present state of the overseas Korean language education centers, and discusses the directions it should take.

본 연구는 여자대학생의 진로결정효능감을 매개로 하여 진로결정자율성과 진로결정관계성이 진로준비행동에 미치는 영향을 알아보기 위하여 서울의 여자대학에 재학 중인 323명을 대상으로 설문을 실시하고 분석하였다. 분석 결과 진로결정자율성과 진로결정관계성이 진로준비행동에 유의한 영향을 미치고 있었다. 진로결정관계성의 4가지 하위척도 중 지지, 모델링, 조언은 유의한 영향을 미치는 반면, 함께 진로준비행동을 하는 동료들과의 관계를 묻는 척도인 활동은 유의하지 않았다. 진로결정효능감은 진로준비행동에 유의한 영향을 미치는 것으로 나타났으며, 하위척도 중에서 직업정보, 미래계획과 관련된 효능감이 높을수록 진로준비행동이 증가하는 반면 목표선택과 문제해결 척도는 유의하지 않았다. 구조모형에 대한 분석을 통해 완전매개모형과 부분매개모형 각각의 모형 적합도를 살펴본 결과, 두 모형의 적합도가 모두 양호하게 나타났다. 두 모형 중 더 나은 모형으로 최종모형을 확정하고자 X2검증(△X2(1)=18.29, p<.01)을 하여 부분매개모형이 더 적합함을 확인하였다. 최종 모형에서 진로결정관계성은 직접 및 간접 경로가 모두 유의하나 진로결정자율성의 직접 경로는 유의하지 않고 간접 경로만 유의함을 확인하였다. The purpose of the present study was to investigate the mediating effect of career decision-making self-efficacy between career decision-making autonomy, career decision relatedness and career preparation behaviors of female college students. The study samples were composed of 323 female university students located in Seoul. For data analysis, the use of correlational analysis, regression analysis, structural equational modeling(SEM), AND sobel test. The results of this study are as follows. First, each of career decision-makingautonomy, career decision relatedness and career decision-making self-efficacy effects significantly to career preparation behaviors. The information of job and the future planning subscale of career decision-making self-efficacy and the support, modeling and advice subscale of career decision relatedness had a more positive effect on career preparation behaviors. Second, mediating effects were examined that the link between career decision-making autonomy, career decision relatedness and career preparation behaviors were partially mediated through career decision-making self-efficacy. This study suggests especially that a career counseling program or career coaching program for female college students can incarease the career decision-making autonomy with career decision-making self-efficacy, which will positively affect their career preparation behaviors.
