Objectives : to evaluate the effects of Jetongdan, the newly developed herbal medicine, on the quality of life in patients with osteoarthritis of knee Methods : Placebo-controlled, randomized clinical trial on the 80 patients with osteoarthritis of the knee was fulfilled. After enrollment, they took medication as they enrolled. And they were asked to answer the questionnaires (Korean Health Assessment Questionnaire (KHAQ), Lequesne's functional index (LF1), visual analogue scale (VAS)) and analysed with the erythrocyte sedimentation rate (ESR) at baseline, after 4 weeks and 8 weeks of medication. Results : Total KHAQ score, some categories of KHAQ like hygiene, activities were significantly improved after 8 weeks of medication. And the change of the KHAQ score was significantly correlated with the change of VAS. But LFI, VAS, ESR level was not significantly improved, and it was considered because of the short medication period and small size of study population. Conclusion : In conclusion, Jetongdan could improve the health-related quality of life in patients with osteoarthritis of knee. Further study in the large population, in long period were recommended.

In this paper, combustion characteristics ignited by single-hole and multi-hole plasma jet igniter and conventional spark plug have been studied by means of schlieren photography and pressure measuring in the Wedge type, Pent-roof type and Toroidal bowl type constant volume vessel which is typical 4-valve SI engine combustion chamber. It is represented that combustion characteristics ignited by conventional spark plug ignition are hardly influenced by configurations of combustion chamber. I contrast in case of plasma jet ignition combustion duration and combustion enhancement rates are effected than spark plug ignition. Consequently, it is important to avoid plasma jet impingement against combustion chamber wall , and to let flame front move toward wide place in the combustion chamber at early stage of combustion.

미래 사회를 대비하기 위한 개인의 개성을 존중과 창의적인 능력을 지닌 인간을 양성을 목적으로 충청남도 지역의 초 ㆍ 중고등학생들을 대상으로 한 창의력 경연대회가 공주대학교 과학교육연구소에서 개최되었다. 충청남도 초 ㆍ중 ㆍ 고등학생들을 대상으로 실시한 창의력 경연대회는 창조적 아이디어를 내어 스스로 문제를 해결해 나갈 수 있는 교육 프로그램을 제공하는 좋은 기회였음이 확인되었으나, 일부의 팀에서만 참신하고 재미있는 아이디어들이 제안되었다. 여학생의 참가자 수가 상당히 증가하였으며, 대체적으로 입상권의 학생들의 상당 부분이 여학생이라는 것이 특이할만하다. 학년이 올라감에 따라서 창의적인 아이디어를 내는 양이나 질에 있어서 뒤떨어지는 것으로 분석되었으며, 토론 학습의 적응력이 미흡하고 발표력 및 청취력에 있어서도 떨어지는 것으로 나타났다. 따라서 중 ㆍ고등학교의 학교교육에서도 학생들에게 프로젝트형 탐구학습 프로그램의 적용은 물론 토론식 수습을 통한 학생들의 사고의 전환의 기회를 제공해야 할 것으로 사료된다. The creativity competition was held to foster the creativity of elementary and secondary school students in the Institute of Science Education, Kongju national University. It was found that the creativity competition effected on the improvement of inventing creative ideas and problem solving activities. But, only some competitors participated in semifinal and final contests, presented original and interesting ideas. More female students participated in competition than last year. More female participants were awarded a prize than males. Totally, participants were defective in discussion and communication, and presentation and listening ideas. Increasing grades correlated inversely with creativity and originality. There is need of inquiry project teaming programs and presenting opportunities of conversion of thinking by discussing instructions in school

The purpose of this study was to survey the oral health knowledge and the oral health perception of university students in some districts. It divided it into by department for one month in March of 2013, surveyed totally 310 people, and then finally analyzed 302 people. The results are as follows. In the oral health care knowledge, a percentage of correct answers as saying of needing to receive regular check-up once per 6 months was the highest with 97.7%. A percentage of correct answers as saying that food of containing lots of sugar is good for health of teeth was the lowest with 10.9%. The oral health knowledge according to general characteristics was high in women(p=0.036). The age was the highest in 21-22 years old and was the lowest in 25-27 years old(p=0.001). In department, the health department was indicated to be the highest. The natural-science department was indicated to be low, thereby having shown difference(p<0.001). In academic year, sophomore was the highest. Senior was indicated to be the lowest(p=0.030). A case of non-smoking was high in knowledge level(p=0.027). A case of not having part-time job was indicated to be high in knowledge level(p=0.032). A case of recognizing that the whole health status is very healthy was low in oral health perception level(p<0.001). The more perception as saying that the oral health status is very healthy led to the lower even in the oral health perception level(p<0.001). To improve the oral health of college students develop a systematic curriculum and teaching methods are needed for the distressed people.

Background: PPL photography would be a quantitative assessment method for the examination of the properties of human skin. In our previous study, the quantitative difference of the light reflected from skin surface could have been analyzed by PPL photography. Objectives: So, we designed this study to improve the technique using various LEDs of different colors. In addition to PPL, in-house skin conductance meter was used to measure the skin hydration for comparison. Methods: A total of 40 healthy subjects were participated in this study. PPL imaging was taken on mid-cheek, volar aspect of forearm and anterior shin, using white and green LED illuminators. In order to assess skin conductance value, we designed our own probe. Results: First of all, as for glossiness on extremities, the L* value was positively correlated(r=0.33417), a* and b* value were correlated negatively(r= -0.32046, -0.33128) under the green illuminator. Skin conductance value was positively correlated with glossiness(r=0.65258). For dryness of extremities, the b* under the green illuminator was positively correlated(r=0.23339) and negatively with skin conductance (r= -0.80447). Skin conductance value itself showed correlations with CIELAB coordinate L* and a* from green light(r=0.24305, -0.22102). Conclusion: In conclusion, analytic PPL image technique combined with LED would be an efficient way to evaluate the properties of human skin and the results implicated the validity of our in-house conductance meter.
