Purpose: This study aims to test if the age of pregnant women affects the perception, experience, and attitude towards complementary alternative therapy (CAT), by investigating the perception, experience, and attitude of pregnant women under the age of 35, and above 35 (Advanced Maternal Age). The study will 1) find the general characteristics of pregnant women under and over the age of 35 2) compare the perception, behavior, and experience of pregnant women under and over the age of 35, and 3) find the comparison of the perception, behavior, and experience according to the general characteristics of pregnant women under and over the age of 35. Method: The subjects of this study are composed of 44 women under the age of 35 and 44 women above the age of 35, totaling 88 pregnant women visiting midwiferies, obstetrics and gynecology, and baby fairs in Seoul and Gyeong-Gi area. Data for this study was collected from November 28, 2015 to January 6, 2016 for 40 days. The collected data analyzed mean, standard deviation, t test, ANOVA, and chi-square by using SPSS 23.0. Result Results show that there is a significant difference in the perception, attitude, and experience of the two-sample groups in the use of CAT. The question of “what is most necessary when applying CAT in a hospital clinical environment” for the perception criteria came out with the results of t=9.980, p<.05. For the attitude, results showed that the answers of pregnant women under the age of 35 displayed a more positive attitude towards CAT. (t=2.421, p<.05) Lastly, in the experience section, pregnant women under the age of 35 showed more CAT use than the other sample group. Conclusion Results have shown that there is a difference in the perception, behavior, and experience between the two sample groups. Therefore further research on the efficacy and the adverse effects of CAT needs to be done.

Objective: Mutations in the p53 gene, one of the most common genetic alterations in human cancer, are implicated in tumorigenesis and tumor progression. Wild-type p53 negatively regulates the cell cycle; a loss of function by mutation might be expected to result in enhanced proliferating activity and tumor progression. A large number of immunohistochemical studies have confirmed p53 accumulation to be a very common feature of human malignancy. The aim of the present study was to determine whether p53 status in gastric cancer is correlated statistically with various histopathological indicators or not. Methods and Materials: A total of 197 surgically resected gastric adenocarcinomas were examined to determine whether a correlation exited between immunohistochemical expressions of the p53 protein and other histopathological factors. Results: p53 overexpression was observed in 46.2% of the gastric cancers. Overexpression of p53 was correlated with vascular invasion of gastric cancer(p=0.004). In early gastric cancer, the p53 overexpression rate was 42.3%, and of them, a correlation was found between the intestinal type of the Lauren classifcation(p=0.013) and histologically differentiated gastric cancer(p=0.014). Conclusion: p53 overexpression was significantly correlated with vascular invasion of gastric cancer. In cases of early gastric cancer, p53 overexpression was correlated with Lauren classification and differentiation. These results suggest that p53 mutation plays an important role in carcinogenesis in gastric adenocarcinomas. Further study in needed to determine the correlation between p53 overexpression and the prognosis for the gastric cancer patient.

To investigate the function of chloroplast small heat shock protein (HSP), transgenic tobacco plants (Nicotiana tabacum L, cv. SR-1) that constitutively overexpress the rice chloroplast small HSP (Oshsp26) were generated. Effects of constitutive expression of the Oshsp26 on thermotolerance were investigated with the chlorophyll fluorescence. After 5-min incubation of leaf discs at high temperatures, an increase in the Fo level, indication of separation of LHCII from PSII, was mitigated by constitutive expression of the chloroplast small HSP. When tobacco plantlets grown in Petri dishes were incubated at 52℃ for 45 min and subsequently incubated at 25℃, leaf color of wild-type plant became gradually white and all plantlets were finally died. Under the conditions in which all the wild-type plants died, more than 80% of the transformants remained green and survived. It was also found that the levels of Oshsp26 protein accumulated in transgenic plants were correlated with the degree of thermotolerance. These results suggest that the chloroplast small HSP plays an important role in protecting photosynthetic machinery, as a results, increases thermotolerance of whole plant during heat stress.

The purpose of the present research was to provide basic materials for groping for the methods that promote adolescents' self-identity through the utilization of the internet. After scrutinizing the actual conditions of adolescents' use of the internet, this study examined the effect of adolescents' family environment, friendships, and use of the internet on their self-identity. Specifically, the present research sought to explore the utilization of the internet by sociodemographic and family environment variables, the effect of background variables on the psychological variable, as well as the relative effects of background variables and the internet-related variables on the psychological variable. The major findings of the study were as follows: The effect of the various variables on adolescents' self-identity showed that the higher the levels of school record, communication with fathers, communication with mothers, intimacy of friendships, and the use of the internet, and the lower the degree of the internet addiction, the higher the level of self-identity. The findings of this research indicate that the level of internet utilization and its addiction among family environment-related variables exerted significant influence on self-identity. This implies that the proper use and guidance of the internet is crucial to adolescents' self- identity, and the use of the internet needs to be guided by families, schools, and communities.

This study was conducted to detect the allelopathic effect of water and ethanol extracts from 4 plant species (Lactuca sativa L., Ambrosia elatior L., Oenothenra odorata Jasp., Ginkgo biloba L.) on germination and growth of lettuce seeds. A little bit higher inhibitory effect was obtained in ethanol extracts rather than water extracts. Allelopathic effects varied in the source of extracts and concentrations of 4 plant species and the highest allelopathic effect appeared in 10% solution, regardless of plant species.

빠르며 정확하고 안전한 치아이동을 목표로 삼고 있는 교정치료에서 최근 새로이 도입된 피질골 절제술과 견인 골형성술을 응용한 치아이동에 대하여 알아보았다. 특히 견치나 대구치의 후방이동은 기존의 치아 이동 양식으로는 조절이 어렵고, 장기적인 기간에 불가피한 치아이동이다. 피질골 절제술과 견인 골형성술을 동반하여 상당히 효과적인 원심이동을 기할 수 있었던 증례를 통하여 적용 술식, 견인 장치 등을 논하고 그효과를 파악하였다. 이런 술식을 통해 빠른 치아 이동과 이에 따른 전반적인 치료기간의 감소가 가능하였으며, 무리한 치아이동에서 발생할 수 있는 고정원 소실이나 치근흡수, 치주조직의 파괴 같은 부작용도 줄일 수 있었다. Tooth movement facilitated by corticotomy and distraction osteogenesis was discussed. In this study, a portion of cortical bone which can provide resistance to tooth movement in alveolar bone was removed. Active bone deposition was then possible in the tension side. Teeth moved at such a speedy rate as we could not imagine from conventional orthodontic treatment, which lead to the reduction of the total treatment period. Posterior movement of the canine or molar teeth was possible without any side effects such as anchorage loss, root resorption or periodontal breakdown.

To investigate the function of chloroplast-localized small HSP in rice, the cDNA, Oshsp21, was introduced into rice plants via Agrobacterium-mediated gene transfer system. Calli induced from rice immature embryos were co-cultivated with a A. tumafaciens EHA101 that contained a plasmid, pIHSP21. The efficiency of plant regeneration from the calli co-cultivated with the Agrobacterium was about 30%. PCR and Southern blot analyses using genomic DNA revealed that gene for the chloroplast small HSP was introduced into the genome of rice. Expression of transgene was investigated by northern blot analysis. Results indicate that the transgene, Oshsp21, was constitutively expressed at normal growth temperature.

In an effort to optimize tissue culture responses of zoysiagrass (Zoysia japonica Steud.) for genetic transformation, factors affecting callus induction and plant regeneration were investigated. MS medium containing 3 ㎎/L 2,4-D was optimal for embryogenic callus induction from mature seed. The plant regeneration frequency of 73.3% was observed when embryogenic calli induced in this medium were transferred to N6 medium supplemented with 0.1 ㎎/L 2,4-D and 5 ㎎/L BA. Among several basic media, MS and N6 medium were optimal for callus induction and plant regeneration, respectively. Regenerated plants were grown normally when shoots transplanted to the soil. A rapid and efficient plant regeneration system established in this study will be useful for molecular breeding of turfgrass through genetic transformation.
