The objective of the present study is to evaluate a practical approach for enhancing the compressive strength andminimizing deforming of aerated concrete. Test results measured in the aerated concrete mixes that were producedusing 40% ground granulated blast-furnace slag (GGBS) as a replacement of cement and cured under differentconditions (i.e., high temperatures of 40℃ and 60℃ for 10 hrs or 15 hrs) were compared with those obtained from thespecimens cured under room temperature. No deforming was observed in the mixes with 40% GGBS. The compressivestrength of the prepared aerated concrete cured under high temperature was higher than that of the concrete cured atroom temperature, even at the lower ranges of the apparent dry density. However, the curing time is needed to becontrolled as not exceeding 10 hrs at the temperature of 60℃ to prevent the decrease in the compressive strength dueto foam mergences. 이 연구의 목적은 기포 콘크리트의 소포를 제어하면서 압축강도를 높일 수 있는 실용적 조건을 평가하는 것이다. 시멘트 양 대비 고로슬래그를 40% 혼입한 기포 콘크리트를고온조건(40℃ 및 60℃의 온도에서 10시간 및 15시간)에서양생 후 측정한 실험결과를 상온양생 조건의 경우와 비교하였다. 고로슬래그를 40% 혼입한 기포 콘크리트에서 침하는발생하지 않았다. 고온양생을 실시한 기포 콘크리트의 압축강도는 낮은 밀도 범위에서도 상온 양생한 기포 콘크리트의강도보다 높았다. 하지만 기포간 병합으로 인한 압축강도저하를 방지하기 위해서는 양생온도 60℃에서 그 지속시간을 10시간 이하로 제한할 필요가 있었다.

박종범 한국ITS학회 2013 한국ITS학회논문지 Vol.12 No.6

영상취득 장치를 이용한 지능화된 감시 장치의 개발 기술 또한 발전하고 있다. 이 분야의 기술 영역은 감시하고 있는 장소에 어떤 사람이나 물체를 탐지하는 전경 분리 기술과 사람이나 물체의 이동 경로를 파악하는 추적 기술로 나뉜다. 본 논문에서는 이동체를 탐지하는 기술로서 잡음이나 조도의 변화에 비교적 안정적인 엔진개발을 위한 개선된 알고리즘을 제안한다. 논문의 제안 알고리즘은 사람이나, 동물, 또는 비교적 저속 운행 중인 차량 등의 탐지에 적합한 모델로서, 조도의 변화나 잡음에 안정적이면서 실시간 처리가 가능한 방법을 고안하는 데 주안점을 두고 있다. A developed skill of an intelligent CCTV is also advancing by using its Image Acquisition Device. In this field, area for technique can be divided into Foreground Subtraction which detects individuals and objects in a potential observing area and a tracing technology which figures out moving route of individuals and objects. In this thesis, an improved algorism for a settled engine development, which is stable to change in both noise and illumination for detecting moving objects is suggested. The proposed algorism from this thesis is focused on designing a stable and real time processing method which is perfect model in detecting individuals, animals, and also low-speeding transports and catching a change in an illumination and noise.

This experiment was carried out to investigate the effects of heavy metals (cadmium, chromium, copper and lead) on the seed germination of Arabidopsis thaliana, and examinated the removal effects of biostone and green tea on the heavy metal toxicity. Cadmium and chromium among the four heavy metals had no effect on the seed germination even in the concentration fifty times higher than in the official standard concentration of pollutant exhaust notified by the Ministry of Environment. However, seeds were not germinated in the concentration of copper ten times higher and in the concentration of lead fifty times higher than the official standard concentration. When seeds were sown in the solutions of lead (15, 20, 25 and 30 ㎎/L) and copper (15 and 20 ㎎/L), the seed germination rates were 0% and less than 10%, respectively. However, when biostone (3 g/30 ㎖) was added, the seed germination rate was 100% in all the concentrations. The germination rate was 100% in distilled water and copper solution (5 ㎎/L). However, green tea (0.2 g/30 ㎖) was added, the seed germination rate was 0% in both. The results show that cadmiun and chromium had no effect on the seed germination, but lead and copper decreased the rate of seed germination of Arabidopsis thaliana. Biostone removed heavy metal toxicity, but green tea did not removed heavy metal toxicity during germination.

Looking at the problem of aging in the nation from a demographic perspective, it is not a problem of the overall population, but of the structure of the population. It is the baby boomer and post-baby boomers, the largest population in the country. Baby boomers were born between 1955 and 1963, and currently have a population of 7001,333, which is 13.6 percent (as of 2015). The Post-Baby Boomer generation was born between 1964 and 1974, with a total population of 9,567,171, accounting for 18.8 percent of the total population. In particular, baby boomers and post-baby boomers (32.4% of the total population) have begun to retire or will retire soon. The average life expectancy continues to increase due to the development of medical technology, and the falling birth rate of newborns and the declining population of the production population are darkening the domestic economy. In a policy proposal aimed at easing the nation's falling economic growth rate, women's participation rate is as high as Sweden and men's efforts to increase it as high as Japan's, while the elderly rate is desirable to maintain Korea's high level. This is because the expansion of the elderly generation's participation in economic activities could ease a sharp drop in economic growth and reduce the burden of supporting the elderly population. The study, based on this social problem awareness and problem solving plan, looks at the relationship between career orientation and satisfaction in start-up education based on the diverse career base of active seniors, and also suggests the importance of customized start-up education on the diversity of active seniors by clarifying the relationship between them, and suggests the desirable direction of senior start-up policy design, funding, and start-up education. Based on the theoretical background, the concept of five factors was defined: active senior, career-oriented, satisfaction level of start-up education, willingness to start a business, and the concept definition of an active senior, which is particularly key to the baby boomers in their 50s and 60s, is generally regarded as a source of consumption or welfare benefits, but in this study, the concept of active start-up is reflected in the domestic start-up market by young people in their 40s, 50s and 60s. As a result of a hypothesis test. Hypothesis 1 and Hypothesis 5: Career orientation has been verified to affect the willingness to start a business and the behavior of preparation for a start-up. Hypothesis 3: The willingness to start a business has been verified as having an effect between startup preparation actions. Hypothesis 4: The satisfaction level of start-up education has been verified to affect start-up preparation behavior. However, hypothesis 2: The satisfaction level of education for start-ups does not affect the willingness to start a business. Such results can be inferred that satisfaction in start-up education does not have a direct effect on the will to start a business and increases the will to start a business through the influence of personal career orientation. 국내의 고령화 문제를 인구학적 관점에서 바라보면 전체 인구수의 문제가 아니라 인구구조가 문제이다. 국내에서 규모가 가장 큰 인구 집단은 베이비부머, 포스트 베이비부머 세대이다. 베이비부머 세대는 1955~1963년생으로 현재 인구는 700만 1,333명이며, 전체인구의 약 13.6%(2015년 기준)를 차지한다. 포스트 베이비부머 세대는 1964~1974년생으로 총인구는 956만 7,171명으로 총인구의 18.8%에 해당한다. 베이비부머 세대와 포스트 베이비부머 세대(총 인구대비 32.4%)가 은퇴를 시작하였고, 조만간 은퇴할 예정이다. 의학기술의 발달로 평균 수명이 지속해서 증가하고 있으며, 신생아의 출산율 저하, 생산인구의 감소는 국내의 경제를 어둡게 하고 있다. 이런 사회적 문제 인식과 문제 해결안으로 본 연구는 액티브 시니어들의 다양한 경력기반에 기초한 경력지향성과 창업 교육 만족도가 창업 의지, 창업 준비 행동에 미치는 영향 관계를 살펴보고, 또한 이들 간의 관계를 규명함으로써 액티브 시니어의 다양성에 대한 맞춤형 창업 교육 중요성을 제안하고 시니어 창업정책 설계 및 자금지원, 창업 교육의 바람직한 방향을 제시하고자 한다. 이를 위해 이론적 배경을 바탕으로 액티브 시니어, 경력 지향성, 창업 교육 만족도, 창업 의지, 창업 준비 행동의 5개 요소의 개념을 정의하고, 특히 핵심이 되는 액티브 시니어의 개념적 정의를 베이비부머 세대인 50대, 60대로 비즈니스의 핵심소비 주체나 복지혜택의 수급대상자로 보는 것이 일반적이지만, 본 연구에서는 국내의 창업 시장에서의 40대, 50대, 60대 순으로 연령별 창업기업 수가 높은 것을 반영하여 액티브 시니어 창업가를 예비시니어(Pre Senior)를 포함한 경력, 경제력, 소비력을 갖추고 활발한 활동과 건강한 삶을 지향하는 40대에서 60대까지 세대를 액티브 시니어로 정의하였다. 가설검증 결과로 가설 1과 가설 5에서 경력 지향성은 창업 의지와 창업 준비 행동 영향을 미치는 것으로 검증되었다. 가설 3에서 창업 의지는 창업 준비 행동 간에 영향을 미치는 것으로 검증되었다. 가설 4에서 창업 교육 만족도는 창업 준비 행동에 영향을 미치는 것으로 검증되었다. 그러나 가설 2에서 창업 교육 만족도는 창업 의지에 영향을 미치지 않는 것으로 나타났다. 이와 같은 결과는 창업교육 만족도가 창업 의지에 직접적인 효과는 미치지 못하고 개인적인 경력 지향성의 영향을 통해 창업 의지를 높이는 것으로 나타났다. 본 연구 결과를 활용하여 액티브시니어 창업정책 수립 방향 수립에 의미를 제공한다.

녹두(Vigna radiata W.) 줄기의 조직 배양에서 기관분화에 관한 조직학적 연구

박종범 新羅大學校 1995 論文集 Vol.39 No.1

The effects of the plant hormone on the growth of the callus tissue and the organogenesis from the stem of mung bean (Vigna radiata W.) seedlings were examined 2.4-D was more stimulated on the growth of the callus tissue than 1AA or NAA among the same concentration auxin supplemented with the MS medium, and kinetin was much more effective than BAP among the same concentration cytokinin. The apical tip was much more effective for the callus formation than the other portion of the stem. NAA(12.8%) was much more effective for the organogenesis from the callus than 2, 4-D (4.4%) or IAA(0.0%) among the same concentration auxin added in the MS medium, and kinetin (12.5%) was a little more effective than BAP (10.0%) among the sytokinin. Hence, it can be explained that the MS medium supplemented with 2, 4-D 0.5mg/l + kinetin 1.0 mg/l was the most effective for the callus growth in the callus culture of the mung bean stem. And the MS medium supplemented with NAA 0.75 mg/l + kinetin 1.50 mg/l was the most effective for the organogenesis from the callus tissue.

Geminivirus에 감염된 Arabidopsis 줄기의 이상세포분열에 관한 세포조직학적 연구

박종범,이석찬 한국식물생명공학회 1998 식물생명공학회지 Vol.25 No.3

Arabidopsis thaliana에 beet curly top virus (BCTV)를 인공접종하여 외부병징 및 조직내부구조 변화를 광학현미경으로 검경하였다. BCTV-Logan에 접종된Arbidopsis thaliana ecotype Sei-O 줄기에서 약 2주 후 이상비대현상이 관찰되었고, 약 4주 후에는 캘러스조직이 형성되었다. 감염된 각 시기별로 증상부위의 Sei-O 줄기를 횡단절단하여 관찰한 결과 다음과 같은 순서, (1) 사부조직의 이상비대, (2) 이상비대된 사부의 괴사, (3) 괴사조직의 lacuna 형성, (4) lacuna형성된 사부 주위의 피층과 표피세포 신장 및 확대, (5) 신장된 피층 및 표피세포에서의 세포분열 유도, (6) 캘러스 조직의 유도 순으로 내부구조 변화가 관찰되었다. BCTV에 감염된 Arabidopsis에서의 캘러스 형성은 바이러스의 감염결과로 유도되었으며, azure-A염색법에 의해 바이러스 inclusion body는 사부조직과 캘러스에서도 존재함이 관찰되었다. 본 연구 결과 BCTV에 감염된 Arabidopsis에서 관찰된 캘러스 형성의 원인은 감염된 숙주식물의 사부조직의 괴사에 따른 lacuna 주위 피층세포의 세포분열에 기인한 것으로 사료된다. The internal structures of Arabidopsis thaliana infected with beet curly top virus (BCTV) were studied by light microscopy. Hyperplasia was observed in the inflorescence stems of Arabidopsis thaliana ecotype Sei-O at 2 weeks after BCTV-Logan inoculation and callus was induced on symptomatic tissues at 4 weeks after virus inoculation. The infection processes were revealed as follows: hyperplasia of phloem tissue, necrosis of hyperplastic phloems, lacuna formation of necrotic tissues, elongation and enlargement of cortex and epidermal cells surrounding the lacuna formed phloem tissues, induction of cell division in the enlarged cortex and epidermal cells, and induction of callus tissue. Callus formation on Arabidopsis was caused by the virus infection, and virus inclusion body was observed in both phloem and callus tissue by azure-A staining.

흡수성 차폐막으로 조직 유도 재생술시 골이식재가 성견 치주조직 재생에 미치는 영향

박종범,임성빈,정진형,김종여,Park, Jong-Beom,YIm, Sung-Bin,Chung, Chin-Hyung,Kim, Jong-Yeo 대한치주과학회 2000 Journal of Periodontal & Implant Science Vol.30 No.1

The present study evaluated the effects of guided tissue regeneration using biodegradable membrane, with and without calcium-phosphate thin film coated deproteinated bone powder in beagle dogs. Contralateral fenestration defects(6 × 4 mm) were created 4 mm apical to the buccal alveolar crest on maxillary canine teeth in 5 beagle dogs. Ca-P thin film coated deproteinated bone powder was implanted into one randomly selected fenestration defect(experimental group). Biodegradable membranes were used to provide bilateral GTR. Tissue blocks including defects with overlying membranes and soft tissues were harvested following a four- & eight-week healing interval and prepared for histologic analysis. The results of this study were as follows. 1.......The regeneration of new bone, new periodontal ligament, and new cementum was occurred in experimental group more than control group. 2.......The collapse of biodegradable membranes into defects were showed in control group and the space for regeneration was diminished. In experimental group, the space was maintained without collapse by graft materials. 3........In experimental group, the graft materials were resorbed at 4 weeks after surgery and regeneration of bone surrounding graft materials was occurred at 8 weeks after surgery. 4.......Biodegradable membranes were not resorbed at 4 weeks and partial resorption was occurred at 8 weeks but the framework and the shape of membranes were maintained. No inflammation was showed at resorption. In conclusion, the results of the present study suggest that Ca-P thin film coated deproteinated bone powder has adjunctive effect to GTR in periodontal fenestration defects. Because it has osteoconductive property and prohibit collapse of membrane into defect, can promote regeneration of much new attachment apparatus.
