In management of unerupted dilacerated tooth, the surgical removal has been indicated. In some cases however, the tooth can be preserved by means of forced eruption. We treated 9 year 3 month old girl with upper left central incisor unerupted and dilacerated. After the mucoperiosteal flap was reflected, lingual button was bonded on the lingual surface of the crown and ligature wire was tied and twisted through the flap into the oral cavity. The tooth was tractioned for 11 weeks by removable orthodontic appliance and retained for 2 months. At this stage, endodontic treatment was done for post and core was built of screw pin and resin core material. Then composite resin temporary crown was cemented on the tooth.

This study was carried out to investigate the effects of soybean oil and salt on the mechanical texture and sensory characteristics of Dongbu-Mook (Cowpea Starch Gel). As the amount of the soybean oil was increased, the hardness and chewiness of the Mook were decreased. But there were no significant difference in the cohesiveness and springiness. While the Mook samples made with commercial Dongbu-Mook flour didn't show a significant difference, those made with lab-manufactured Dongbu-Mook flour without salt showed higher hardness, chewiness than the ones with salt. The Mook made of commercial Dongbu-Mook flour was found to be higher in the hardness and lower in the cohesiveness than the one made of lab-manufactured Dongbu-Mook flour. In sensory evaluation, as the amount of soybean oil was increased, all the samples showed higher yellowness and greasiness, and lower clarity, hardness and chewiness. For the samples with salt, the yellowness was high, and the hardness was low. The Mook samples with lab-manufactured Dongbu-Mook flour had low chewiness. There was no significant difference in the clarity and greasiness. Overall, the Mook samples made with commercial Dongbu-Mook flour showed the best quality, when soybean oil was not added and salt was added. For the Mook made with lab-manufactured Dongbu-Mook flour, the sample with 2% oil and salt was the best.

Aristolochia manshuriensis KOM. distributed in the northern parts of Kangweon Province centering Mt. Seorag in Korea is a vigorous and climbing vine. It has been used widely as one of ingredients of chinese medicine. The unusual flowers by virtue of their shape and hue are beautiful, flowered in May and matured in October. The large leaves are coarse in texture, and have been used as arbor, trellis, pergola, and pillar. Therefore, it is now considered as an excellent ornamental plants for Landscape. The objectives of this study were investigation of the suitable propagation methods, comparison of the influence of bed temperature for hardwood cuttings, and determination of the effectiveness of various rooting promotion treatments. The results obtained were as follows. The germination rate 53% when the period of stratification was 70 days. The rooting percentage, rootlet number, and length of root male plants are generally better than those of female plants. The female and male plants cuttings tended to have the largest root system in the 20℃-bed temperature. The female plants treated with 20℃, IBA 1000ppm and 25℃ IBA 1000ppm. The male plants treated with 20℃, IBA 500ppm rooted well.

The existence of gender gaps in the Programme for International Student Assessment (PISA) scores has been documented in the literature. In particular, it was revealed that on average Korean female students underperform/outperform their male counterparts in mathematics/reading scores for PISA 2012. This study was conducted to examine crucial determinants in understanding gender differences. We examined whether or not the influence of educational contextual variables on mathematics, reading and science achievement differs by gender using multilevel model with each group of male and female students. As a result, there were variables that had more influence on male or female students, though there were some differences by subject. It can be concluded that females have been affected more by teachers than by parents, while males have been affected more by parents. Also, creative extracurricular activities had much more of an effect male students than females. In addition, participation in math-related activities only influenced females, and academic and vocational expectation in math and class management of math teachers only influenced male students. Based on the results, we proposed an educational and political plan that may bridge disparity gaps in academic achievement by gender.

沈慶久,安永熙,柳美先,劉鍾勳 成均館大學校 科學技術硏究所 1984 論文集 Vol.35 No.2

Bittersweet(Celastrus orbiculatus) grown widely in the mountains of Korea is perennial, deciduous and climbing plant. They have strong vines, flower from May to June and mature in October. The red coloured fruits are beautiful, use as the cut-flower materials, and also as the food of birds. This is now considered worthwhile to exploit as an outstanding landscape plant. The objectives of this study were investigation of the suitable propagation methods, reaffirmation of the utility of mist room for softwood cuttings, influence of bed temperature for hardwood cuttings, and determination of the effectiveness of various rooting promotion treatments. The results obtained were summarized as follows. The germination rate was 70% when the period of stratification was 50 days. In softwood cuttings, the rooting percentage and rootlet number tended to be greater in closed moist chamber than those in mist rooms. The rooting percentage, rootlet number and length of root in the 25℃-bed temperature were higher than those in the bed of 20℃ or 30℃ in hardwood cuttings. Cuttings treated with IBA 1000ppm rooted better than those received other hormone treatments in hardwood and softwood cuttings.

This study analysized an immune reaction with 7 students from the department of dance and 7 students from that of general education of J High School of arts. An immune reaction in immunoglobulin of IgG, IgA, IgM were reduced during menstrual than in nomal times. Also an immune reaction showed many changes. From this, the trail of studying immune in cells would be great helpful for athletes to increase their infection and contests.

The honeysuckles constitute a sturdy group of semievergreen vines, some which can be grown in everywhere of the native mountains. As a group, they are not susceptible to serve disease troubles, which are easily grown and will usually produce a wealth of foliage, flower and fruit with very little care. They are perenial and deciduous climbing plants with strong vines, and flowered from June to September that are considerd as a good ornamental plants for Landscaping. Plants of honeysuckle are ordinarily able to be rooted from softwood or hardwood cuttings, the cutting itself being about 4-5cm long. This study was carried out to determine the effectiveness. of various rate of IBA and NAA treatment on rooting of honeysuckles (Lonicera japonica, Lonicera japonica var. aureoreticulata, Lonicera sempervirens) in the mist room and closed moist chamber. And the results obtained were as follows. Treatment of IBA and NAA increase! in the rooting percentage, rootlet number and length of root on the rooting of honeysuckle cuttings. The rooting percentage of honeysuckle cuttings with IBA 2000pprn 10 sec dip are higher than other rooting hormone treatment. IBA showed more promoting .effect than NAA treatment on the rooting of leafy softwood cuttings. Rooting percentage and number of root tended to have the hightest root system in the closed moist chamber than the mist room.

Objective : This study is a follow-up of a first survey of 200 North Korean defectors who entered South Korea in 2001. The purpose of this study is to examine changes in the current prevalence of partial PTSD and full PTSD after 3 years and to evaluate related factors. Methods : This study followed up on 151 of the 200 North Korean defectors from our first survey. 20 interviewers conducted face-to-face interviews and assisted defectors in completing a self-report assessment. The traumatic events which participants with chronic PTSD and delayed onset PTSD experienced were then examined. Results : Over the 3 years, the current prevalence rate of partial PTSD was reduced from 31.8% to 5.3%, and the current prevalence rate of full PTSD was reduced from 27.2% to 4.0%. Of particular interest was that 88.8% of those diagnosed with full or partial PTSD in the first survey had recovered after 3 years. Conclusion : The current prevalence rate of partial and full PTSD rapidly decreased during 3 years.
