We have studied the grinding characteristic for three kind of ceramics in diamond wheel grinding process, and have also found the optimal conditions to get the best surface roughness under above mentioned process for ceramics. Considering the wheel grains in grinding of Si₃N₄and ZrO₂ceramics, the surface roughness has related with the amount of load applying on wheel as varying the feed rate owing to the minute destruction phenomenon of grains in grinding of Si₃N₄ and ZrO₂ceramics. For the case of Al₂O₃. the depth of cut has related with the surface roughness as grinding is carried out by grain shedding process due to the brittleness destruction phenomenon. The major factors affecting the surface roughness and the optimum grinding conditions have also obtained by using the design of experiment.

Background : The cun measurement System, an essential and convenient method in locating acupoints, has been widely used in the practice of acupuncture. However, traditional cun measurement has been criticized for its lack of reliability. Objectives : The purposes of this study are to determine if one cun measured by the directional methods have a consistency with that of proportional methods and to investigate which factors are related with these differences, especially in forearm. Methods : The distance between the elbow crease and the wrist crease of forearm was compared to a reference value of one cun obtained by the directional method. In this method, one cun is one third of the distance between index finger and Small finger of a subject, measured at proximal interphalangeal joint. In addition, to investigate the factors influencing the differences between these two methods, we measured the height and body weight and calculated body mass index (BMI). Finally we analyzed the factors correlated with these lengths by linear regression test. Results : The results showed that one cun obtained by the directional methods were significantly different from one cun by the proportional methods in forearm. It was demonstrated that the length acquired with the directional method was more correlated with body weight and body mass index, while the length obtained by the proportional method was more correlated with the height.

In this study, experiments were carried out to investigate the characteristics of ceramic material s for grinding and wear process by diamond wheel. Normal component of grinding resistance of A1₂0₃was less than that of Si₃N₄ and Zr0₂. This seems to be the characteristics of ceramic material generating between toots and work pieces both of high hardness. For the case of Si₃N₄ and ZrO₂ as the grain mesh number of wheel increases, the surface roughness decreases. For the case of Al₂O₃, the surface roughness does not decreases, Specific grinding energy decreases as the chip removal rate increases. Si₃N₄ and ZrO₂ materials is grinded by abrasive wear processes but Al₂O₃ material is grinded by grain shedding process, i.e, brittleness destruction

Pyrifluquinazon, as a quinazinalone chemical group, based on a new mode of biological activity. It is reported that mode of action is modifies insect behavior, rapidly stopping feeding such that insects starve to death. Time-release feature and mortality effect on M. persicae using different pyrifluquinazon nano type and non-nano type were compared. Pyrifluquinazon nano type was formulated with different molecular weight and density of used chitosan (CS 30000 0.1% and CS 3000 0.3%). In the CS 30,000 0.1%, the mortality was weakly occurred at early time, but steadily increased after 4days. Finally, we confirmed more than 70% mortality as a peak at 16days. In CS 3000 0.3%, the mortality showed about 70% until 18days as a effective controlled release. Also, We examine time-release feature and mortality effect on M. persicae according to the different pyrifluquinazon nano type(CS 30000 0.1% and CS 3000 0.3%) of concentrations. The CS 30000 0.1% bioassay results of different concentration were showed that the highest concentration(100ppm) was measured better mortality than other concentration at 0 day, but cannot confirm different effect about dissimilar concentration. However, increasing rates of M. persicae were low as treatment concentrate was high. In CS 3000 0.3% 100ppm concentration bioassay result, aphid mortality reached peak at 24 days and increasing rate also low. Additionally, for the comparing of bioassay and feeding behavior of M. persicae against pyrifluquinazon nano types and non-nano type, EPG technique was carried out. In case of non nano type, feeding inhibition efficacy was showed during 4 days after treatment, but appeared similar level with control after 10days. In CS 3000 0.3% 50ppm, residual efficacy was specially showed until 28days after treatment whereas treatments with CS 30000 0.1% were similar to the control after 22days. These result show that the change of feedinng behavior and motrality of M. persicae is correlated with the change of nano type or non nano type of pyrifluquinazon.

학교폭력 이슈에 대한 보도경향 분석: 1997년∼2012년 종합일간지와 교육전문지 뉴스보도를 중심으로

강연곤 ( Youn Gon Kang ),유홍식 ( Hong Sik Yu ),강태현 ( Tae Hyun Kang ) 한국지역언론학회 2013 언론과학연구 Vol.13 No.2

본 연구는 국내 주요 일간지와 교육전문지가 학교폭력 문제를 어떠한 관점으로 다루고 있는지를 분석하였다. 분석대상 일간지는 <조선일보>, <동아일보>, <경향신문>, <한겨레>, 교육전문지는 <한국교육신문>과 <교육희망>이었다. 분석 시기는 학교폭력이 사회적으로 중요하게 이슈화된 3개 시기(1997년, 2005년, 2011/2012년)이었으며, 이 시기에 포함된 학교폭력 관련 기사 784건을 추출하여 기사에 나타난 뉴스프레임을 분석하였다. 분석결과, 국내 일간지들은 사건을 단순 전달하는 ‘사건 전달 프레임’, 학교폭력에 대한 대책을 다루는 ‘대책 강구 프레임’을 ‘원인 규명 프레임’보다 많이 사용한 것으로 나타났다. 분석된 3개 시기별로는 1시기에서 사건 전달 프레임과 대책 강구 프레임이 비슷한 비중으로 사용된 반면, 15년 정도가 지난 3시기에서는 대책 강구 프레임의 비중이 약간 높았다. 대책강구 프레임의 하부 프레임인 ‘감시-처벌 강화’ 프레임의 비중은 1시기에 비해 3시기에 대폭 줄어든 반면(1시기, 34.3%→3시기, 12.8%), ‘교육적 처방’ 프레임의 비중(1시기, 5.6%→3시기, 12.4%)은 증가하였다. 교육전문지는 분석 대상 기사의 81.3%가 대책 강구 프레임을 사용한 것으로 나타났다. 아울러, 학교폭력 가해자와 피해자의 대립구도를 다루는 기사에서는 정보 제공형 기사제목보다는 관심 유도형 기사제목의 사용 비중이 높았다. This study analyzed Korean newspapers` coverage on school violence issue. This study utilized frame analysis technique on a total of 784 selected news articles from four daily newspapers that represent both conservative and progressive voices and two education magazines. The results shows that Korean newspapers mainly used governmental policy frame on school violence issue. The governmental policy frame was most frequently utilized in the progressive newspapers and the education magazine. Incident cause evaluation frame has increased from 1997 to 2012. However, Korean newspapers tended to convey incidents of school violence, or governmental policy without in-depth investigation. This study also showed the newspapers reported contrast of at tacker-victim of school violence emotionally, and used frequently attention-attracting headlines to attract readers` attraction. Finally, this study shows that Korean newspapers fail to interpret the problem of school violence in depth.
