본 논문에서는 기존의 Motion-JPEG 기반 감시시스템에서 낮은 동영상 압축성능 문제를 해결하기 위한 새로운 동영상 압축기법을 제안하였다. 제안된 방법에서는 현재 프레임의 JPEG 데이터 중 변화된 압축 데이터만이 실시간으로 추출하고 저장된다. 제안된 방법에 의해 저장된 데이터는 기존의 JPEG과는 다른 고유의 포맷을 가지기 때문에, 동영상 데이터는 더욱 안전하게 유지될 수 있다. 실험을 통해, 제안된 동영상 압축기법의 압축률이 기존의 Motion-JPEG 기반 감시시스템에 비해 3배정도 높다는 것을 확인할 수 있었다.

Surface treatments of Y2O3:Eu phosphors for improving the hydrophobic property were carried out using plasmas generated from a O-(Si(CH3)3)2 (HMDSO) in a low-pressure environment. The super-hydrophobic properties of the treated Y2O3:Eu phosphors were investigated. The samples treated by using the HMDSO/toluene glow plasma were analyzed by FTIR and OES and analyzed in terms of their contact angles (CAs). The effects of the HMDSO/toluene plasma treatments on the Y2O3:Eu phosphors were investigated in terms of the total surface free energy by using probe liquids to measure their contact angles (CAs). The total surface free energy of the Y2O3:Eu phosphors before and after a surface treatment with the HMDSO/toluene plasma, as estimated via the Owens-Wendt equation, was found to decrease from 82.2 mJ/m2 to 0.021 mJ/m2. This represents a significant improvement of the hydrophobicity of the Y2O3:Eu phosphors after the plasma treatment.

Purpose: The purpose of this study was to determine the sexual knowledge, and sex education perception and current status of the parents of preschoolers. The objective was to analyze the relationship between sexual knowledge and sex education demands of parents. Method: The method used in this study was a descriptive correlationstudy. The subjects were 278 parents of 3-to-6 year old children in 5 kindergartens located in Seoul. Data were analyzed using frequency, percentage, average, standard deviation, t-test, ANOVA, Scheffe test, and correlation using the SPSS 20.0 program. Result: The results of this study were the following: 1.There was no significantdifference in the sexual knowledge between the father and mother of preschoolers (Father 20.76, Mother 20.73). According to the findings, sexual knowledge was higher when both father and mother were older (P=.005). Similarly, when the economic level of the father and mother was high, sexual knowledge was also high (P=.030). 2.Concerning sexual education perception, it was found out that both father and mother thought that sex education was necessary. 3.In terms of sex education, a significant difference was noted. Mothers conducted sex education more often than fathers (Fathers, 46.7% Mother, 60.3%). Both the father and mother thought that providing sex education would be best in Grades 1-2, especially for ages 6-7. 4.When asked about the demands for sex education in terms of the physical, social, and living aspects, living aspect was the highest demand. It was revealed that both fathers and mothers were aware of the need for sex education, and when parents hadmore sexual knowledge, they would demand more sex education. Accordingly, there was a correlation between parent’s sexual knowledge and demand for sex education (r=.202, p=.001). Conclusion: Since the age,knowledge, education and economic levels of parents were different, it was necessary to develop sexeducation programs in accordance with their levels. In this way, preschooler parents would be able to teach sex education appropriate to their children’s level.

We obtained regenerated Italian ryegrass (Lolium multiflorum Lam.) plants by anther culture. When Italian ryegrass anther was incubated for 20 days on callus induction medium, MS medium containing 30 g/ℓ of NAA and 1 mg/ℓ of kinetin its callus was induced. The ratio of callus induction was 9.2 %, the mean of callus weight was 8.6 mg/callus/anther. When Italian ryegrass callus was incubated for 50 days on plant regeneration medium, MS medium containing 30 g/ℓ of sucrose, 1 mg/ℓ of NAA and 2 mg/ℓ of kinetin, Italian ryegrass plant was regenerated. The ratio of plant regeneration was 26%.

Objectives: The purpose of the study was to identify the relationships between cybersex addition, loneliness and relationship satisfaction among Korean college students. Methods: 293 students were conveniently selected. The instruments used in this study were cyber-sexual addiction index, loneliness scale and relationship assesment scale. ANOVA, t-test and Pearson correlation coefficient with SPSS 22.0 Version were used to analyze the data. Results: 8.9% of the participants had moderate or severe addiction to cybersex. The level of cybersex addiction is significantly influenced by gender, period of relationship, time taking to sexual relations, contact number of cyber pornography and contact time of cyber pornography. Significant association was observed between cybersex addition, loneliness and relationship satisfaction. Conclusions: The factors mentioned in this study as well as loneliness and relationship satisfaction were important factors. Therefore, future studies on this topics need to develope interventions to reflect cultural and physical character of college students.

To obtain the informations on the checking factors of the effecient utilization of paddies in chungnam province and study on the effecient working system and high productive cropping system in paddies, the utilization state of paddies including environmental conditions were investigated at sample 1,500 farms. The results obtained are summarized as follows; 1. The difficulty of drainage in paddies was the most important factor checking the utility of paddies. Delayed transplanting of rice and lack of labour were also important checking factors on the efficient utilization of paddies. 2. The utilization of paddies was rather effecient at small size farms of which farmers were almost poor, and most of them cultivated barley for their own food. 3. Considering climatic conditions, pre-crops of rice must be harvested before June 10 th, and the marginal transplanting date of rice plant is June 25 th. 4. In case of planting barley as a post-crop after rice, the spread seeding by rotary before plowing was most efficient with lowest cost. 5. Considering rice cultivation, yield of barley and net income, the most efficient cropping system was "Josaengtongil+Olbori".

Valproate is an effective epileptic drug to control partial seizure and infantile spasm specially but the therapeutic range is narrow, so it is objective of TDM. The efficacy and safety of drug therapy depends on the bioavailability and the dissolution and content uniformity tests are very important procedures for the controlling of medication bioavailability. This study selected three enteric-coated valproate tablet that is administered to patients 2 or 3 times daily in Asan Medical Center and evaluated the bioavailability by the dissolution test and content uniformity test, attempted to estimate that the release of valproate in vivo is suitable for present drug therapy or not. The dissolution test was performed in the solution Ⅰ and the solution Ⅱ that was made by K.P. 7 for three hours and all sample were measured by HPLC. The results were as followed : (1) The mean dissolution amount in the solution I was higher in order of three different brands B (14.9%) > A (7.52%) > C (2.45%) (2) The mean dissolution amount in the solution Ⅱ was higher in order of three different brands B (114%) > A (102%) > C (22.2%). (3) The content uniformity was higher in order to B (117.6%) > A (110.3%) > C (85.8%). In conclusion, the dissolution of A and B in vivo seems to be suitable for present drug therapy but the release of C in vivo seems to be not.
