The purpose of this study was to evaluate the efficacy of adding autogenous bone to the toothash-plaster mixture in the healing process of bone. Full-thickness round osseous defects with the diameter of 20mm were made at the calvarial bone of adult dogs (n=19) bilaterally, which were thought to be critical size defect. The right defects were repaired with the toothash-plaster mixture plus autogenous bone (compressed volume 0.3cc) and the left defects with only toothash-plaster mixture. At 2-, 4-, 8-, 12- and 20- week after implantation, dogs were sacrificed and evaluated the osseous healing of bony defects clinically, radiographically, and microscopically. The results were as follows : 1. At the clinical observation, the wound healed very well without any problem except severe swelling in the early period after operation. Slight depression was recognized at the both sides when the portions of cranial defect were palpated. 2. There were statistically significant differences between toothash-plaster mixture groups and autogenous bone added groups at the same period, and among the groups in the bone density of the digital radiograms (P<0.001).There was a tendency that bone density was increasing with time. 3. In light microscopic examination, new bone formation was more active in the autogenous bone added groups than toothash-plaster mixture groups at the early period after mplantation but there is little difference at 20-week after implantation. 4. In fluorescent microscopic examination, the fluorescent band could be observed at the area of active bone formation and the band was more distinct in the autogenous bone added groups then toothash-plaster mixture groups. 5. In transmitted electron microscopic examination, organelles such as rER, Golgi complex and secretory granule and osteoblast were observed. In summary higher volume ratio of autogenous bone is needed to improve the bone healing in that there is little difference between toothash-plaster mixture group and autogenous bone added group at the 20-week after implantation in spite of new bone formation was more active in the autogenous bone added groups than toothash-plaster mixture groups at the early period after operation.

This study was conducted to find the effect of in-class nutrition education and exercise program for obese adolescent boys in Taegu with the nutrition knowledge test before and after education program and anthropometric measurement. The subjects were consisted of a normal group (NG; n=13) and an obese group (n=30). The obese group is divided into two groups; obese group A (OG-A; n=12), participated in a ten-week nutrition education only; and obese group B (OG-B; n=28), participated in a ten-week nutrition education and exercise program. The anthropometric data of the three groups were increased after the nutrition education program. However the obesity index(BMI, R hrer, WHR, Skinfold thickness) of OG-B were significantly decreased after the programs. The nutrition intake data were also changed after the nutrition education program. Especially the intake of carbohydrate was significantly decreased in OG-B from 421.5±155.9g to 349.0±41.0g (p<0.05) after the nutrition education program. It was noted that the intake of Ca was significantly decreased in all three groups after the nutrition education program. The mean score of the nutrition knowledge test also significantly increased from 13.7±3.1 to 17.8±3.0 after the nutrition education program. The result strongly suggested that nutrition education program should be successful if the obese adolescents and their parents especially mothers participated in the same class. In summary, nutrition education and exercise programs were effective on reducing obesity of obese adolescents. Nutrition knowledge of obese adolescent was significantly increased after nutrition education program.

This study report the decolorizing technology of coloring waste pieces in order to recycle the cutting fabrics from a sewing factory in Indonesia. With a view to achieve an aim as abovementioned, I applied the oxidation method 1 and the reduction method to the decolorizing of coloring waste pieces by using tumble dyeing machine. The conclusions obtained from the this study were as follows. Coloring waste pieces with 100% cotton materials were obtained the desired effect by oxidation method 1. Coloring waste pieces with P/C materials were obtained the desired effect by oxidation method 1 and reduction method. Some of them were recycled the goods such as fabrics, knitted fabrics, yams, and also another part of them were recycled the goods such as socks and gloves. Some part(about 1%) of the whole which made as dope dyed yams recommended which was not recycled. The most economical concentration of oxidation and reduction agents was 10g/ℓ, the optimum decolorizing time was 40 minutes in both method. A difference in decolorizing effects was not found between tumble dyeing machine and decolorizing machine in this study. And then, decolorizing differences were not shown between a domestic goods and Indonesian goods in this study. I found it easy to decolorize more Indonesian goods in it than domestic goods.

방혜진,이승우,최근원,정인식,설일환 慶熙大學校 1997 論文集 Vol.26 No.-

Studies were carried out to investigate the effect of cultural media on callus growth and anthocyanin production using the callus derived from the leaf discs of the Populus hybrid (Populusnigra × Populus maximowiczii cv. Yanghwangchul). Callus growth was the best in SH medium supplemented with 30 g·liter^-1 sucrose whereas anthocyanin production was maximum in White medium. But the amount of anthocyanin biosynthesis per vessel was the best in SH medium. Callus growth was similar in SH medium containing sucrose, fructose of glucose, but anthocyanin biosynthesis was enhanced in SH medium containing sucrose. Sucrose concentrations of 3.5% was the best for both callus growth and total amount of anthocyanin biosynthesis per vessel. Maltose suppressed both callus growth and anthocyanin biosynthesis. Callus growth was enhanced by higher concentrations(2X) of KNO_3 and CuSO_4, and by standard concentrations(1X) of CaCl_2 and H_3BO_3 in the medium. Total amount of anthocyanin biosynthesis was, however, somewhat different from the pattern of salts effects on callus growth.

정선희(Jung, Sun Hee),김인설(Kim, In Sul) 한국예술경영학회 2017 예술경영연구 Vol.0 No.42

이 연구는 국립아시아문화전당의 성인대상 문화예술교육 유료강좌인 ‘ACC 시민아카데미’를 수강한 고객들을 대상으로, 첫 수강 이후 다음 시즌의 유료강좌를 연속 신청한 이들의 충성도 형성과정을 자기결정성이론(self-determination theory)을 통해 분석한 질적 사례 연구(qualitative case study)이다. 연구참여자 선정은 ACC 시민아카데미 상반기 강좌를 수강한 이후 연속하여 하반기 유료강좌를 신청한 이들로, 이 중 하반기 수강강좌가 최소 3건에서 최대 5건에 이르는 다섯 명의 수강자들을 유의표집방법(purposive sampling)을 통해 모집했다. 연구의 분석결과, ACC시민아카데미의 연속수강자들의 주요 동기요인은 외적요인 이외에도 수강자들이 본래 가지고 있는 타고난 성향 또한 중요한 기제로 밝혀졌다. 주요 외적요인으로 새로 개관한 기관에 대한 기대감과 유명인사의 수준 높은 강의 등이 초기 선택에 긍정적 영향을 미치는 것으로 밝혀졌으나, 이는 최초 수강에 있어 주요한 판단 자료로 쓰일 뿐 충성도와 연관된 연속수강에 판단에 있어서는 다양한 요인들이 복합적으로 작용하는 것으로 드러났다. 이러한 일련의 과정은 예술교육 유료강좌의 연속수강자에 대한 충성도 형성과정을 보다 면밀히 학술적으로 살펴 볼 수 있는 기회를 제공한다는 점에 있어 이전의 연구와 차별성을 갖는다. 본 연구의 목적은 문화예술기관이 제공하는 교육프로그램을 관객개발을 위한 전략적 접근방법 중 하나로 상정하여, 연속 수강자의 충성도 형성과정을 학술적으로 조망하고 이에 대한 함의를 예술경영적 차원에서 심층적으로 도출하는데 있다. This study is a qualitative case study that focuses on continuing participants who have successively enrolled in paid arts education programs, ACC Civic Academy , offered by Asia Culture Center; to examine their motivation to participate and customer loyalty construction by adopting a self-determination theory. For data collection methods, continuos observations and personal in-depth interviews were used. The research participants were selected by a purposive sampling method for five members who have successively enrolled in at least three to five paid arts education programs compare to one paid education program in the previous season. The results of the study show that these continuing participants are strongly driven by their inner motivations, such as their personalities and treats, rather than external events. Still some external events, such as their high expectation on a newly opened cultural complex, ACC; high-quality arts education programs; and famous lectures, displayed important roles for affecting them to participate in such program at the beginning. However, in terms of their choices for the continuing enrollment and loyalty construction have been far more influenced by delicate and various factors. This study is unique in a way that attempts to academically explain the process of the loyalty construction of arts education participants who continuously willing to pay for their learning. The aim of this study is to broaden the discussive scope on the arts education participants’ loyalty construction by applying an arts managerial perspective, based on the belief that arts education is a strategy for effective audience development.

HClO₄(pH:2) 수용액에서 양극산화 방법으로 HgMnTe(HMT)의 표면에 산화막을 형성 시켰다. 산화막의 두께는 SEM으로 측정하였으며 10㎛였다. 전류-전압 특성곡선을 얻어 산화 피크 전압으로부터 HTeO₂?, TeO?, HHgO₂? 막이 형성되었음을 알 수 있었다. 산화시키지 않은 HMT와 HClO₄수용액에서 산화시킨 HMT에 대해 Hall전압 및 자기저항을 각각 측정하였다. 홀전압과 자기저항은 HMT보다 HMT산화막에서 더 컸으며 이것은 HHgO₂? 공격자가 홀의 역할을 하고, TeO₄? 산화막은 전하의 포획도를 낮게하기 때문으로 생각할 수 있다. Anodic oxidation processes on HgMnTe surface has been studied in standard aqueous HClO₄(pH:2) solution. The 10㎛ thickness of the anodic oxide layers was measured by SEM. The Composition of the anodic oxide layers are evaluated from current-voltage(I-V) characteristic of HgMnTe Oxidation. The layers are composed of mixed oxide. ??, TeO₄, and?? in HClO₄solution. Transport properties have been investigated in HMT oxide layer made in HClO₄solution and virgin HMT samples at 300K. Hall voltage and magnetoresistance are greater in oxide layer HMT than virgin HMT. As a result, we know that the vacancy of ??in an anodic oxide layer acts as hole and the resulting oxide ?? layer exhibit a reduced degree of charge trapping and increase magnetoresistance.

The annealing effect of Bi₂Sr₂Ca₁(Cu₁-xFex)₂O8+δ (x=0, 0.003, 0.006, 0.009) single crystal have been studied. The single crystal was grown in air by developed directional solidification method and subsequently annealed for 8 hours at 700℃. The structure of grown singel crystal is measured through X-ray diffraction measurement. We measured resistivity by standard four probe method in the range of temperature from 20 K to 250 K. As the quantity of Fe is increased from x=0 to x=0.009. Tc is decreased from 89 K to 77 K. Tc of annealed samples are smaller than that of as-grown sample.
