Spent pig bone was consist of hydroxyapatite. And then we thought that it have a possibility as a adsorbent. The preparation of bone char prepared from spent pig bone in this study. We study on the recycling possibility as a adsorbent is able to adsorb copper ion from their single aqueous solutions. The results are summarized as follows. Bone char that prepared from spent pig bone at 105, 400, 700℃. The adsorption removal efficiency of copper ion onto bone char as adsorbent was above 90% for 15 hours. Increase in the initial pH of the copper ion solution result in an increase in the copper ion uptake per unit weight of the adsorbent. Freundlich isotherm model was found to be applicable for the experiment data of copper ion. The results showed that spent pig bone can be used for the absorption of the copper ion.

Restoration of neutral mechanical alignment of the lower limb is an important factor in the treatment of unicompartmental arthrosis. Traditionally, medial opening wedge high tibial osteotomy has been widely performed to correct varus malalignment with unicompartmental arthrosis. However, an ideal indication for the high tibial osteotomy is the knee with metaphyseal tibial varus malalignment. The basic principle of corrective osteotomy is performing an osteotomy at the center of the deformity to prevent abnormal joint line obliquity. If pathologic distal femoral varus deformity is the cause of genu varum, the osteotomy should be performed in the distal femur. Reports of medial opening wedge distal femoral osteotomy (DFO) to correct varus malalignment are rare. We present a case of this very rare and challenging condition in a 47­year­old male, which was successfully treated by medial opening wedge DFO.

Identification and characterization of individual components of M.tuberculosis have long been a focus of research on tuberculosis. The 30-kDa and 32-kDa antigens are major constituents of M bovis BCG and M. tuberculosis culture fluids. Because 30-kDa and 32-kDa antigens are partially identical, these antigens are difficult to purify in large amounts by biochemical techniques. This study was performed to purify the 30-kDa and 32-kDa antigens complexes primarily purified by 50% ammonium sulfate precipitation, hydroxylapatite chromatography and Sephadex G-75 gel filtration. And then further purification for separation of the two antigens was accomplished on preparative isoelectric focusing. Recovery of 30-kDa and 32-kDa antigens during above the purification procedures were 28% and 14%, respectively, and 147.0 and 59.8-fold purification were showed, respectively. On silver stained SDS-PAGE gels, the purified 32-kDa antigen gave a single band at 32-kDa molecule, while 30-kDa antigen gave one major band at 30-kDa molecule and faint additional band at 32-kDa. The pI of 30kDa-and 32-kDa antigens were 4.3 and 4.6, respectively. The partial identity between these two antigens was observed through the same pattern of reactivity of antigens in the ELISA and precipitation pattern of immunodiffusion. We also examined the immunological activities of both purified antigens by splenocyte proliferation of BCG-infected mice. Proliferative response to the 30-kDa and 32-kDa antigens did not show significant difference. However, macrophage-like cells existed in spleen cells from BCG-infected mice were involved in the suppression of the proliferative response to mycobacterial antigen. These results suggest that the 30-kDa and 32-kDa antigens could be effectively purified by the IEF and reactions of partial identity between the two antigens were found. However, 30-kDa antigen was the more immunogenic antigen than 32-kilodalton.

The incidence of double primary cancer is about 10% in all kinds of cancers. Double primary cancer is usually accompanied by gastrointestinal cancer. Esophageal cancer is supposed to be frequently accompanied by squamous cell carcinoma of the head and neck or the upper respiratory tract, because of such common carcinogens as smoking and alcohol ingestion. Esophageal cancer and hypopharyngeal cancer are usually diagnosed by esophagogastric endoscopy with biopsy. We performed endoscopic ultrasound-guided Trucut biopsy(EUS-TCB) to diagnose a mediastinal mass in a 49 year-old patient, who visited our hospital because of voice change. During procedure, we accidently found enlarged celiac lymph node, and obtained tissue from the mediastinal lymph node and the celiac lymph node. We confirmed double primary cancer of squamous cell carcinoma in the esophagus and the hypopharynx via esophagogastric endoscopy.

석·박사 학위논문에서 생리적 변수를 다룬 연구에 대한 분석 : 1962년부터 1996년까지 발표된 국내 학위논문을 중심으로 with reference to the thesis published in Korea from 1962 to 1996

Objectives : The studies in biological, behavioral and psychosocial perspectives in nursing research are fundamental in the balanced development of nursing knowledge. Many nursing researchers have placed a strong emphasis on developing psychological and behavioral aspects of nursing knowledge as is evidenced by the large body of research in these areas. However, the paucity of nursing research using the principles of biological science for measurements and techniques have often invited open criticism by many nursing researchers. This study attempts to characterize the researches performed in master and doctoral thesis which used physiological variables. Methods : We analyzed masters' thesis from 1962 to 1996 and doctoral thesis from 1982 to 1996 listed in CD from Korean Nurses Association. Results : Out of 3060 masters' thesis from 1962 to 1996, 342 (11.2%) thesis used physiological variables whereas 43 (10.1%) doctoral thesis used physiological ones. Number of thesis with physiological variables was the highest in Seoul National University for masters' thesis whereas for the doctoral thesis the number was the highest in Yonsei University. The research subjects in these thesis with physiological variables were mostly patients (53.5% in masters' and 69.8% in doctoral). Master's thesis often conducted either nonexperimental or survey research (69.9%) whereas experimental research design prevailed vital signs(l81 thesis), blood tests(133), body composition(124), microorganisms(74), gastrointestinal functions(36), lab test(33), drug(2l), urinary functions(20), movement(l7), Apgar Score(l5), reproductive functions(9), skin related functions(6), body fluid and electrolytes(4), parasite(4), metabolism(3), and sensory(1). Among the 338 master' thesis which studied the common nursing concepts such as anxiety, pain, stress, and depression, 48(14.2%) thesis utilized physiological variables while 15 out of 35 doctoral thesis addressed these concepts using physiological variables. Conclusion : In summary, our results indicate that despite the large amount of nursing research performed over the last decades, there are a few nursing researches done with physiological variables either in masters' or doctoral thesis. To enrich nursing knowledge with different perspectives of nursing including especially biological ones, the efforts have to be made to conduct bionursing science research.

프로그램 분위기와 프로그램 관여도에 따른 PPL효과 연구

김정현,이명천,김지은 한국방송광고공사 2008 광고연구 Vol.0 No.78

This study is designed to investigate PPL effects by program mood and program involvement.An experiment was performed to test 4 hypotheses about the main effect of program mood on PPL and interaction effect of program mood and program involvement. 288 subjects were conveniently sampled and randomly assigned to experimental groups. This study adopted 2×2 factorial design by the program mood(positive vs negative) and program involvement(high vs low). The findings were as follows: Firstly, the main effect of program mood was supported. That is, the recall of PPL brand was significantly high when the program mood was negative. And the attitude toward PPL brand was significantly positive when it placed in positive program mood than in negative program mood. Secondly, program involvement and program mood caused interaction effect only to the recall of PPL brand. That is, the brand recall increased when the program mood was negative and the program involvement was low. However, program involvement and program mood did not cause interaction effect to the attitude of PPL brand. 급격한 매체 환경 변화로 촉발된 광고 환경의 변화로 인해 광고효과에 대한 의문이 제기되면서, 광고주 및 실무자들은 전통적인 광고의 약점을 극복하고 설득효과를 제고시킬 수 있는 새로운 방법을 모색하게 되었다. 이에 영화나 드라마 속에 제품을 제시하는 대표적 혼합 메시지라 할 수 있는 PPL(product placement)은 이러한 욕구를 충족시켜 주는 새로운 마케팅 수단으로 활용되고 있다. 본 연구는 국내외적으로 PPL의 활용빈도가 점증하고 있는 현실에 비해 PPL효과를 다룬 실증 연구들이 충분히 축적되어 있지 못한 국내 연구 현실을 고려하여 프로그램 분위기와 프로그램 관여도에 따른 PPL효과를 실험연구를 통해 알아보았다. 구체적으로 본 연구는 PPL효과(브랜드 회상과 브랜드태도)를 종속변인으로, 프로그램 분위기(긍정적/부정적)와 프로그램 관여도(고/저)를 독립변인으로 하는 2×2 요인설계방안을 채택하고 대학생을 대상으로 실험을 실시하였다. 연구 결과 긍정적 분위기보다 부정적 분위기의 프로그램에서 제시된 PPL의 브랜드 회상이 높게 나타났고, 부정적 분위기보다 긍정적 분위기의 프로그램에서 제시된 PPL의 브랜드태도가 높게 나타났다. 따라서 본 연구 결과를 토대로 프로그램 분위기가 PPL에 미치는 효과는 검증되었다고 할 수 있다. 그러나 프로그램 분위기와 프로그램 관여도가 PPL에 대해 상호작용효과를 유발하는가를 검증해본 결과, 브랜드 회상의 경우만 유의하게 나타나 부분적으로만 검증되었다고 할 수 있다.

Background : The bc1-2 protein, contrast to p53, has been shown to be suppress the apoptosis, and overexpression of the bc1-2 protein has been reported in several malignant tumors. Although how the bc1-2 protein takes part in tumorgenesis has not been proved, the bc1-2 positive tumors appeared to have good prognosis in some malignant tumors. The expression pattern of the bc1-2 in keratinocyte originated skin tumors have not been well known. The authors analyzed immunohistochemically expression of the bc1-2 protein to invastigate the role of the bc1-2 protein in developing skin tumors. Method : 21 squamous cell carcinoma, 19 basal cell carcinoma, 9 keratoacanthoma 11 seborrehic keratosis and 9 Bowen's disease were immunostained with anti-bc1-2 monoclonal antibody. Results : 1. The bc1-2 negative reactions were seen in all cases of sqaumous cell carcinoma, keratoacanthoma and Bowen's disease. The basal layer in keratoacanthoma and Bowen's disease shown to be intense positive reaction in bc1-2, whch suggested of the protected barrier function from tumor cell invasion into the dermis. 2. The bc1-2 were positive in all basal cell carcinoma. 3. In seborreheic keratosis, 9 cases were negative and 2 cases were positive. The positive cases appeared to be resulted from invagination of the basal cells in the epidermis. Conclusion : The bc1-2 protein did not appear to express in full matures cell, but positive reaction are seen in proliferating activity cells. The bc1-2 positive cells are rahter not abnormal cells than have function of protection of tumor cell proliferation by the prolongation of survival time normal cell.

연구목적 : 정신분열별 환자들을 대상으로 통합심리치료의 소프로그램인 인지분화훈련을 실시하여 실행기능, 개념형성능력, 언어능력 및 추론력에 대한 훈련이 보다 더 하위단계의 인지기능인 주의력, 기억력, 반응시간 등을 호전시킬 수 있는 지를 알아보고자 하였다. 연구방법 : DSM-IV상 정신분열병으로 진단된 24명의 입원환자를 무작위로 양분하여 한 군은 인지분화훈련군으로 다른 한 군은 대조군으로 나누었다. 훈련군은 4주동안 1주일에 3회(매회 60분간)로 총 12회의 통합심리치료의 인지분화훈련을 받았으며 대조군은 동일한 시간동안 정신건강교육을 받았다. 훈련전후에 훈련군과 대조군을 대상으로 개정판 Wechsler 기억검사로 주의집중력, 장·단기 기억력을 측정하였고 Vienna test system중 결정반응시간검사로 반응시간, 반응결정시간, 반응운동시간을 평가하였다. 연구결과 : 1) 주의집중력에서는 훈련군과 대조군사이에 집단간 효과, 집단내 효과 및 상호작용 효과가 없었다. 2) 단기기억력에서는 훈련군과 대조군사이에 집단내 효과는 있었으나(F(1,24)=10.46. p〈.05). 집단간 효과, 상호작용 효과는 없었다. 3) 장기기억력에서는 훈련군과 대조군사이에 집단내 효과는 있었으나(F(1,24)=15.09. p〈.05). 집단간 효과, 상호작용 효과는 없었다. 4) 반응시간에서는 상호작용 효과(F(1,24)=5.18, p〈.05)가 있었다. 5) 반응운동시간에서는 집단간 효과, 집단내 효과 및 상호작용 효과가 없었다. 6) 반응결정시간에서는 상호작용 효과(F(1.24)=6.00, p〈.05)가 있었다. 결 론 : 통합심리치료의 인지분화훈련은 정신분열병 환자에서 하위단계의 인지기능 중 반응시간(특히 반응결정시간)을 단축시키는 효과가 있었다. Objectives : The purpose of this study was to investigate the effects of cognitive differentiation training of Integrated Psychological Therapy(a training program of executive function, concept formation, language, and abstraction) on micro-level cognitive function such as attention, memory and reaction time in patients time in patients with schizophrenia. Methods : Twenty-four inpatients diagnosed as schizophrenia using DSM-IV were randomly assigned to 2 groups. The training group went through a total of 12 sessions of cognitive differentiation training for 4 weeks. The control group received psychoeducation program during the same period. Wechsler Memory Scale-Revised and Decision-Reaction Timer of Vienna Test System were administered to all patients, both before and after the training program. Results : 1) In the attention and concentration scores of Wechsler Memory Scale-Revised, between group, within group and interaction effects of training were not significant. 2) In the short-term memory scores of Wechsler Memory Scale-Revised, within group effect of training was significant(F(1,24)=10.46, p〈0.05), but the between group and interaction effects did not reach significance. 3) In the long-term memory scores of Wechsler Memory Scale-Revised, within group effect of training was significant(F(1,24)=15.09, p〈0.05), but the between group and interaction effects did not reach significance. 4) In the reaction time scores of Decision-Reaction Timer, interaction effect of training was significant(F(1,24)=5.18, p〈0.05). 5) In the motor time scores of Decision-Reaction Timer, between group, within group and interaction effects of training were not significant. 6) In the decision time scores of Decision-Reaction Timer, interaction effect of training was significant(F(1,24)=6.00, p〈0.05). Conclusion : Our findings suggest that cognitive differentiation training of Integrated Psycho-logical Therapy is partly effective on improving micro-level cognitive functions such as reaction time(especially, decision time) in patents with schizophrenia.
