Abeliophyllum distichum, one of the Korean endemic plant, is a significant pharmaceutical plant resource. A. distichum with phenylethanoid glycoside can use to regulate the development of cancer, DNA damage with radicals, and the generation of inflammatory mediators. In this study, we investigated whether the biomass, content of phenylethanoid glycoside, and growth rate of callus derived from A. distichum (cultivar Okhwang1, CAD) change in the absence or presence of plant hormones (2,4-Dichlorophenoxyacetic acid; 2, 4-D and 1-Naphthaleneacetic acid; NAA). The results showed that the best biomass, the growth rate of callus, and the contents of phenylethanoid glycoside were cultivated on Murashige and Skoog (MS) growth medium fortified with 1 ppm 2,4-D + 2 ppm NAA after 4 weeks. In a further study, CAD was cultivated on MS growth medium fortified with an elicitor (Methyl Jasmonate, MeJA). The results showed that CAD turned to brown color and fragile form with the elicitor. HPLC-PDA analysis revealed that the contents of phenylethanoid glycoside in the elicitor-treated group were higher than in the elicitor-non-treated group. These results are consistent with the findings of Arano-Varela H et al.,'s study which is that acteoside production can increase after the treatment of MeJA. Therefore, this study can be used to develop an effective and sustainable production of useful substances as an alternative to plant cultivation.

Background: Trigeminal neuralgia (TN) is one of the most painful disorder in the orofacial region, and many patients have suffered from this disease. For the effective management of TN, fundamental epidemiologic data related to the target population group are essential. Thus, this study was performed to clarify the epidemiological characteristics of TN in the Korean population. This is the first national study to investigate the prevalence of TN in Korean patients. Methods: From 2014 to 2018, population-based medical data for 51,276,314 subscribers to the National Health Insurance Service of Korea were used for this study. Results: The incidence of TN was 100.21 per 100,000 person-years in the year of 2018 in Korea, and the male to female ratio was 1:2.14. The age group of 51-59 years had the highest prevalence of TN. Constant increases in medical cost, regional imbalance, and differences in prescription patterns by the medical specialties were showed in the management of TN. Conclusions: The results in this study will not only help to study the characteristics of TN, but also serve as an important basis for the effective management of TN in Korea.

Thermal properties of layered metal chalcogenides such as $WT_2$ (T=S,Se) with two-dimensionally disordered structure were evaluated. Thermal conductivity shows a marked decrease after exfoliation and subsequent restacking because of random stacking of two-dimensional crystalline sheet, which circumvents thermal conduction pathways along longitudinal direction in anisotropic materials.

Purpose: It was necessary for developing a neonatal classification system based on nursing needs and direct care time. This study was, thus, aimed at identifying nursing activities and measuring the standard nursing practice time for developing a neonatal patient classification system in Neonatal Intensive Care Unit (NICU). Methods: The study was taken place in 8 general hospitals located in Seoul and Kyungi province, South Korea from Dec, 2009 to Jan, 2010. By using 'the modified Workload Management System for critical care Nurses' (WMSN), nursing categories, activities, standard time, and task frequencies were measured with direct observation. The data were analyzed by using descriptive statistics. Results: Neonatal nursing activities were categorized into 8 areas: vital signs (manual), monitoring, activity of daily living (ADL), feeding, medication, treatment and procedure, respiratory therapy, and education-emotional support. The most frequent and time-consuming area was an ADL, unlike that of adult patients. Conclusion: The findings of the study provide a foundation for developing a neonatal patient classification system in NICU. Further research is warranted to verify the reliability and validity of the instrument.

Every one hopes for the strong or healthy families and happy society, The Healthy Families Act legislated on February 9, 2004, and three centers were appointed to perform as a model, before the law has been in force from January 1, 2005. The major services or programs at the Center performed last year were as follows; educational programs, counseling for prevention of family problems, and cultural events for strengthening the family functions. This study presented the general situations of Seoul Yongsan-gu Sookmyung Women's University Center for Healthy Families last year, evaluated the product of cultural events or programs, and proposed better ideas for managing cultural services or programs. In 'the division of Home Culture', the community networks were established, and diverse events or programs provided drew high satisfaction among attendants. In the future, some services or programs at Seoul Yongsan-gu Sookmyung Women's University Center for Healthy Families hoped to be helpful and made a basis for activating services or programs for other centers.

컴퓨터 네트워크는 산업 전반에 응용되고 대중화되어 급속하게 우리의 삶에 파고들고 있다. 이와 더불어 네트워크에 대한 침해도 지능적화, 다양화되어 이에 대한 해결책이 시급한 실정이며 사전에 방지 하기보다는 다양한 네트워크 공격을 받더라도 서비스를 계속할 수 있는 네트워크의 생존성에 관한 사항이 주목을 받고 있다. 이에 본 논문에서는 네트워크의 생존성을 향상시키는 방안으로 IP 통합 관리를 이용하는 방안을 제안하였으며 유 무선 환경에 적용하기 위하여 유 무선 보안 기술을 응용한다. 네트워크의 패킷 모니터링을 통하여 IP/MAC 주소 관리함으로써 관리 네트워크내의 임의의 사용자가 사용중인 네트워크 장비 혹은 PC 의 IP 주소나 네트워크 인터페이스 카드를 임의적으로 또는 악의적으로 변경하는 것을 차단할 수 있고 원과 같은 부적절한 네트워크 현상을 발견하여 시스템을 차단하는 방안을 제시한다.

The incidence of endometriosis in post-operative abdominal scars is rare. We describe two cases of abdominal endometriosis diagnosed by fine needle aspiration (FNA). Both patients presented with subcutaneous masses at previous cesarean section scars with cyclic symptoms of pain. The cytologic smears were cellular and comprised two distinct cell populations consisting of epithelial and stromal components. An epithelial component consisted of flat sheets of polygonal cells and the second stromal component showed crowded clusters of spindle cells or isolated single cells. Hemosiderin-laden macrophages were found in the background. FNA offers a safe and effective tool for diagnosis of abdominal wall endometriosis.

The purpose of this study was to examine the usability of a robot in kindergartens and the children's perceptions of that robot. In order to answer these questions, a field study, picture drawing and interviews were conducted over twelve days in a kindergarten located in Seoul. Our results indicated that children were likely to use the robot in a group and girls tended to use it more than boys. Children's affection towards the robot was positive and they perceived the robot mostly in terms of a friend. Finally, the picture drawing activity differed according to the usability level. Children who were in the high usability level grouping engaged more with educational content and storytelling while the low usability level grouping utilized the robot for singing in a large group.
