This study suggested input variables whose effects have been considered by adjusting various input variables in the TRANSYT-7F and NETSIM, the Simulation programs employed in calculating the delay time at street sections. The results can be summarized as follow. 1. Among the input variables in the TRANSYT-7F needed to calculate the delay time at street sections, the excluded are those which effect the most on time delay, such as bus stops, pedestrian crossings and on/off ramps. Among the input variables the most affecting factors are Saturation flow rate and time delay whose suggested quotients are well summarized in the text of this study. 2. There are variables which affect the change of time delay in the NETSIM, such as bus stop, pedestrian crossing, bus appearance period, and departure time delay. This study did the Simulation program using those variables except pedestrian crossing because, as the result of the correlation analysis suggests, there is a strong correlation between bus stop and pedestrian crossing. In this study, the survey had been done in the morning and afternoon except the Peak time, so heavily congested sections were excluded. And both sides of three street sections were surveyed. Therefore, there should be further studies on heavily congested situations and many other street sections.

The future society is expected to be rapidly change in all areas, that is, the length of change time is becoming much smaller than that of generation time. It is very important to prepare the citizens who possess scientific literacy which actively cope with the rapid changes and specialization of society. The sources of rapid changes may be due to the developments in science and technology. Therefore, the importance of science education will be increasingly high. Scientific literacy should be improved basically and systematically from the early stages of formal education. Teachers who are responsible to educate children should be able to research in the areas of science education as well as science itself, and to have capacity to transmit them to the classroom. To do this, the graduate course and the science education within the system beyond the level of college education are essential parts of teacher education. In the graduate course, it is important that science itself and pedagogy of science should be balanced.

Background and Purposes: Over the past three decades, numerous studies performed in Korea have reported that job stress is a determinant risk factor for chronic diseases and work disability. Every society has its own culture and occupational climate particular to their organizations, and hence experiences different occupational stress. An occupational stress measurement tool therefore needs to be developed to estimate it objectively. The purpose of this study is to develop and standardize the Korean Occupational Stress Scale (KOSS) which is considered to be unique and specific occupational stressors in Korean employees. Subjects and Methods: Data were obtained from the National Study for Development and Standardization of Occupational Stress (NSDSOS Project: 2002-2004). A total of 12,631 employees from a nationwide sample proportional to the Korean Standard Industrial Classification and the Korean Standard Occupational Classification were administered. The KOSS was developed for 2 years (2002-2004). In the first year, we collected 255 items from the most popular job stress measurement tools such as JCQ, ERI, NIOSH and OSI, and 44 items derived from the a qualitative study (depth interview). Forty-three items of KOSS, in the second year, were retained for use in the final version of the KOSS by using Delphi and factor analysis. Items were scored using conventional 1-2-3-4 Likert scores for the response categories. Results: We developed eight subscales by using factor analysis and validation process: physical environment (3 items), job demand (8 items), insufficient job control (5 items), interpersonal conflict (4 items), job insecurity (6 items), organizational system (7 items), lack of reward (6 items), and occupational climate (4 items). Together they explained 50.0% of total variance. Internal consistency alpha scores were ranged from 0.51 to 0.82. Twenty-four items of the short form of the KOSS (KOSS-SF) were also developed to estimate job stress in the work setting. Because the levels of the subscales of occupational stress were gender dependent, gender-specific standard norms for both the 43-item full version and the 24-item short form using a quartile for the subscales of KOSS were presented. Conclusion: The results of this study suggest that KOSS might be an appropriate measurement scale to estimate occupational stress of Korean employees. Further and more detailed study needs to be conducted to improve the validity of this scale.

This report is a part of research on pests occurring in grapevine orchards in export complexes (Hwangsung in Gyeonggi, Sangju and Yeongcheon in Gyeongbuk, Namwon in Junbuk and Yeongdong in Chungbuk) from 2010 to 2012. This research was conducted to evaluate the distribution and difference in damage rates depending on management types of grapevine orchards (domestic sale farm vs. export farm). Damage by Arbordia spp. occurred only in 2010 and differed depending on localities and individual farms in the same area. Numbers of orchards damaged by Arbordia spp. were one, two and four in Hwasung, Namwon and Sangju, respectively, and the damage rate was below 6.2%. There was no damage in the orchards in 2011 and 2012, however, Arbordia spp. were collected on sticky traps in the orchards. A. nigrigena and A. kakogawana were the dominant species in Yeongcheon and Yeongdong, respectively, in 2011. A. kakogawana, A. maculifrons and A. nigrigena were collected on sticky traps in 2012. Collected numbers of Arbordia spp. were different depending on localities and management types of the orchards (domestic sale vs. export). A. kakogawana was the dominant species in all the survey sites and the densities were higher in the domestic sale farms than in the export farms.

Objective The purpose of this study was to examine the effects of the Soma experiencing motion (Soma e-motion) program on interoceptive awareness and self-compassion among novices. Methods A total of 19 adults (clinical group=9, non-clinical group=10) participated in the intervention. Psychological and physical changes after program were qualitatively analyzed using in-depth interviews. The Korean Multidimensional Assessment of Interoceptive Awareness (K-MAIA) and the Korean version of the Self-Compassion Scale (K-SCS) were used as quantitative measures. Results The non-clinical group showed statistically significant differences in the K-MAIA scores (z=-2.805, p<0.01) and K-SCS scores (z=-2.191, p<0.05); however, the clinical group showed no significant differences (K-MAIA: z=-0.652, p>0.05; K-SCS: z=-0.178, p>0.05). According to the in-depth interviews, the results of the qualitative analysis were categorized into five dimensions (psychological and emotional, physical, cognitive, behavioral, and aspects participants found challenging and needs improvement). Conclusion The Soma e-motion program was feasible for improving interoceptive awareness and self-compassion in the non-clinical group. However, further research is needed to investigate the clinical efficacy of the Soma e-motion program for clinical group.

Chae Hyeong Lee,김은정,Min Hee Lee,Ga Won Yim,김경준,김광기,김어진,노주원 대한의학회 2020 Journal of Korean medical science Vol.35 No.24

Anti-N-methyl-D-aspartate receptor (anti-NMDAR) encephalitis is a potentially life- threatening but reversible autoimmune disorder characterized by psychiatric symptoms, cognitive dysfunction, speech dysfunction, seizures, movement disorder, decreased level of consciousness, and autonomic dysfunction or central hypoventilation. It occurs predominantly in young women and approximately half of them have underlying tumors, mainly ovarian teratoma. A 24-year old woman was admitted because of fever, headache, abnormal movement and decreased mental status. Five cycles of plasmapheresis improved her neurological and mental status. Anti-NMDAR antibodies in her CSF and serum were positive, and computed tomography revealed a 1-cm sized mass suggestive of mature cystic teratoma arising from the right ovary. We promptly performed laparoscopic right ovarian cystectomy. She was discharged after 2 weeks with mild memory deficit. Prompt removal of ovarian teratoma and multidisciplinary care are particularly important for good outcome.

벼 흰잎마름병균의 정확한 진단을 위하여 PCR용 진단 kit를 개발하였다. 본 PCR kit를 개발하기 위하여 벼 흰잎마름 병균 유전체 정보 중 phage-related integrase and transposase gene의 염기서열을 이용하여 프라이머를 각각 제작하였다. 프라이머 염기서열은 XOP-F (5-CGG TCT GCT CAA TGA GGA AGA-3)와 XOP-R2 (5-TGC AAT TGG TGT TCTCCA GG-3), XOT-F (5-GTC ATA GGT GAG GCT TCCC-3)와 XOT-R2 (5-AGT GCG ATC TTT CAG CAG G-3)로 벼 흰잎마름병균의 DNA를 401bp와 492bp를 증폭하게 제작하였다. PCR 증폭은 벼 흰잎마름병균만 증폭하였으며 다른 세균인 Escherichia coli, Agrobacterim, Pectobacterium caratovora subsp. cartovorum, P. atrosepticum, Pseudomonasputida, P. syringae, P. savastanoi pv. phaeolicola, P. savastanoipv. savastanoi and P. marginalis pv. Marginalis 등은증폭되지 않아 특이성이 인정 되었다. 본 프라이머로 병이 의심되는 벼잎과 논물에서 병원균을 3시간 이내에 검출할 수 있었다. PCR-based specific identification of Xanthomonas oryzae pv. oryzae (Xoo), the pathogen responsible for bacterial blight (BB) of rice, was developed by amplifying the Xoo-specific phage-related integrase and transposase gene. Therefore, dual primers, XOP-F (5-CGGTCTGCTCAATGAGGAAGA-3) and XOP-R2 (5-TGCAATTGGTGTTCTCCAGG-3) and XOT-F (5-GTCATAGGTGAGGCTTCCC-3) and XOT-R2 (5-AGTGCGATCTTTCAGCAGG-3) were designed and found to specifically amplify 401bp and 492bp fragments from all strains of Xoo isolates from diverse regions in Korea. The PCR products were only amplified from Xoo among other bacterial strains including Escherichia coli, Agrobacterim, Pectobacterium caratovora subsp. cartovorum, P. atrosepticum, Pseudomonas putida, P. syringae, P. savastanoi pv. phaeolicola, P. savastanoi pv. savastanoi and P. marginalis pv. marginalis. This method could also be applied to detect the pathogen in infected rice leaves and paddy field water within 3 hr.

Lee, Sang-Eun,Kim, Neung-Hee,Chae, Hee-Sun,Cho, Shin-Hyeong,Nam, Ho-Woo,Lee, Won-Ja,Kim, Sun-Heung,Lee, Jung-Hark American Society of Parasitologists] 2011 The Journal of parasitology Vol.97 No.1

<P>Abstract The present study assessed the prevalence of Toxoplasma gondii infection in feral cat populations in Seoul using enzyme-linked immunosorbent assay (ELISA) and nested polymerase chain reaction (PCR). A total of 456 feral cats from 17 wards in Seoul was surveyed. The overall prevalence of T. gondii infection was 15.8% (69/456) by ELISA and 17.5% (80/456) by PCR; by gender, 17% (44/259) by ELISA and 16.2% (42/259) by PCR in males and 14.3% (28/196) by ELISA and 19.4% (38/196) by PCR in females. On a baseline of the Han River, prevalence was 15.1% (29/192) by ELISA and 15.6% (30/192) by PCR in the upper region and 16.4% (43/264) by ELISA and 18.9% (50/264) by PCR in the lower area. This suggested that toxoplasmosis is widespread throughout Seoul's feral cat population and it is critical that the city institute policies for the control of the feral cat population to reduce the risk of toxoplasmosis transmission to animals, including humans.</P>
