The soybean cultivar, ‘Saegeum’, has been developed for preparing soy-paste and tofu. The soybean cultivars ‘Daepung’ and ‘SS98207-3SSD-168’ were crossed in 2003 to obtain ‘Saegeum’. Single seed descent method was used to advance the generation from F3 to F5, and the plant lines with promising traits were selected from F6 to F7 by pedigree method. The preliminary yield (PYT) and advanced yield trials (AYT) were conducted from 2009 to 2010, and the regional yield trial (RYT) was conducted in 12 regions between 2011 and 2013. The morphological characteristics of ‘Saegeum’ were as follows: determinate plant type, white flower, tawny pubescence color, and brown pod color. Flowering and maturity dates were August 2, XXXX and October 17, XXXX, respectively. Plant height, first pod height, number of nodes, number of branches, and number of pods were 79 cm, 18 cm, 16, 2.3, and 44, respectively. The seed characteristics of ‘Saegeum’ were as follows: yellow spherical shape, yellow hilum, and the 100-seed weight was 25.4 g. ‘Saegeum’ was resistant to bacterial pustule and SMV in the field test, and its lodging resistance was mildly strong, whereas its shattering resistance was excellent. The ability of this cultivar to be processed into tofu, soybean malt, and other fermented products was comparable with that of ‘Daewonkong’. The yield of ‘Saegeum’ in the adaptable regions was 3.02 ton ha-1. Thus, ‘Saegeum’ is adaptable to mechanized harvesting because of its high first pod height, as well as lodging and shattering resistance. (Registration number: 5929)

Repeated use of ACCase inhibiting herbicides for a long time has resulted in increases of resistant Echinochloa oryzicola populations in paddy fields in middle west area of Korea. This study aims to investigate current status of herbicide resistant E. oryzicola in Gyeongsangnam-do, in which there is less information about herbicide resistance. For resistance frequency and dose-response study, seeds from 100 individual plants of E. oryzicola in Gyeongsangnam-do were collected and tested with cyhalofop-butyl. Seven percent of plants from Gyeongsangnam-do was resistant at a recommended rate of cyhalofop-butyl. $GR_{50}$ values (herbicide rates required to reduce plant growth 50%) for one representative resistant populations and five susceptible populations were $738g\;a.i.\;ha^{-1}$ and 66-234 (average 147)$g\;a.i.\;ha^{-1}$, respectively, indicating average 5 times difference in resistance. Although lower rate of frequency of herbicide resistance in Gyeongsangnam-do than in Jeollabuk-do, increases of herbicide resistance are expected in this area because of increases of direct seeded rice fields and increases of dependence on a specific herbicide. Therefore, it is necessary to monitor herbicide resistance regularly and conduct integrated herbicide resistance management in this area. 경남지역 제초제 저항성 피의 발생현황과 저항성 정도를 알아보기 위하여 벼 재배 논에서 100개체의 피 종자를 수집하여 ACCase 저해제인 cyhalofop-butyl에 대한 약량반응 실험을 수행한 결과, 수집한 피의 7%가 저항성으로 조사되었다. 선발된 감수성 5개체의 $GR_{50}$값은 평균 $147g\;a.i.\;ha^{-1}$로 나타났고, 함양 지역의 저항성 개체의 $GR_{50}$값은 $738g\;a.i.\;ha^{-1}$ 로 R/S (ratio of resistance to sensitivity)값은 5.01배로 나타났다. 현재 경남지역에서의 저항성 피의 발생 수준은 낮은 것으로 나타났지만, 저항성 피의 확산을 지연시키거나 막기 위해서는 주기적인 저항성 피의 모니터링과 체계적인 저항성 잡초 관리방안을 마련하여 수행할 필요가 있다.

<P>Recent changes in healthcare systems have changed the epidemiologic paradigms in many infectious fields including bloodstream infection (BSI). We compared clinical characteristics of community-acquired (CA), hospital-acquired (HA), and healthcare-associated (HCA) BSI. We performed a prospective nationwide multicenter surveillance study from 9 university hospitals in Korea. Total 1,605 blood isolates were collected from 2006 to 2007, and 1,144 isolates were considered true pathogens. HA-BSI accounted for 48.8%, CA-BSI for 33.2%, and HCA-BSI for 18.0%. HA-BSI and HCA-BSI were more likely to have severe comorbidities. <I>Escherichia coli</I> was the most common isolate in CA-BSI (47.1%) and HCA-BSI (27.2%). In contrast, <I>Staphylococcus aureus</I> (15.2%), coagulase-negative <I>Staphylococcus</I> (15.1%) were the common isolates in HA-BSI. The rate of appropriate empiric antimicrobial therapy was the highest in CA-BSI (89.0%) followed by HCA-BSI (76.4%), and HA-BSI (75.0%). The 30-day mortality rate was the highest in HA-BSI (23.0%) followed by HCA-BSI (18.4%), and CA-BSI (10.2%). High Pitt score and inappropriate empirical antibiotic therapy were the independent risk factors for mortality by multivariate analysis. In conclusion, the present data suggest that clinical features, outcome, and microbiologic features of causative pathogens vary by origin of BSI. Especially, HCA-BSI shows unique clinical characteristics, which should be considered a distinct category for more appropriate antibiotic treatment.</P>

In this paper, we propose a face region detection based on skin-color distribution and facial feature extraction algorithm in color still images. To extract face region, we transform color using general skin-color distribution. Facial features are extracted by edge transformation. This detection process reduces calculation time by a scale-down scanning from segmented region. we can detect face region in various facial Expression, skin-color deference and tilted face images.

Self-adjustment module has been introduced for alignment error compensation in a previous paper. Self-adjustment module guarantees accurate arrangement of lens parts during assembly process in spite of alignment error so that remarkable price reduction and miniaturization of assembly machine could be achieved. But this module can not control lens orientation. Cellular phone camera lens is produced by plastic injection molding process, so lens has other special quality according to the orientation. In this paper assembly machine for lens module is designed to control lens orientation.

Work Time scheduling representation is a kind of describing tool for parallel algorithms in the limited number of processors. Most people believe that it is trivial to convert from a parallel algorithm under assumption of the unlimited number of processors to the one in limited version. In this paper we will discuss what the problem is on this conversion and show how the general arithmetic expression is correctly represented by Work Time Scheduling as an example.

Objective : Tetanus decreased in prevalence since the systemic vaccination began in 1940s. Despite of the improvement in treatment like critical care with ventilatior or antibiotics, the mortality rate resides around 45%. Currently the tetanus prevention protocol recommends immunization in infancy and boosters every tenth years. Thereafter the immunization with toxoid only or toxoid plus immunoglobulin injections is recommended according to the type of injury. In most of ED in Korea, only tetanus immunoglobulin is given without any basis. Previously we proved the effect that passive immunization with the immunoglubulin 250 IU last long for only a month. At this time we measured the effect of the active immunization with toxoid and its effect was compared to the effect of the tetanus immunoglobulin to find out the logical tetanus prevention after an injury. Method: 20 healthy adult volunteers were injected with tetanus toxoid and their anti-tetanus antibody titers measured before the injection, 1 week and 4 weeks after the inection. No volunteers have taken any medication for chronic illness(e.g. hepatits, tuberculosis) or had an tetanus immunization or booster in the last 6 months. Antibody titers were measured by IMMUNOZYM??-TETANUS and t-test was performed on the results, Results: 1. Total 20 volunteers(12 males and 8 females) were participated. 2. Subjects` ages were 21 to 44 years old and there were no relevance to the antibody titer. 3. The antibody titers of before the anti-tetanus toxoid injection and 1 week, 4 weeks after the injection revealed significant difference and the antibody titers of the first and the forth week after the injection also showed a significant difference. Conclusion: Currently in Korea, the tetenus immunoglobulin 250 IU given alone as tetanus prevention was injected, but it did not elevate the anti-tetanus antibody titer for 4 weeks where as tetanus toxoid injected intramuscularly did significantly. Therefore, tetanus toxoid should be given on the dirty injuries with additional tetanus immunoglobulin injection to accomplish the correct method of tetanus, tetanus toxoid prevention.
