Citrobacter species is a gram-negative bacilli that can cause opportunistic infections in immunocompromised hosts. Citrobacter braakii refers to the genomospecies 6 of the Citrobacter freundii complex. There are no detailed studies on infections caused by this newly identified specific genetic species in Korea. We herein report a case of a patient with hepatocellular carcinoma who, after undergoing transcatheter arterial chemoembolization, developed biloma which later progressed to C.braakii sepsis and did not respond to treatment. To our knowledge, this is the first reported case in Korea on C. braakii infection resulting in septic shock in a patient with malignancy in Korea.

Ultraviolet (UV) is thought to induce erythema, sun-burn, photo-toxicity, photo-allergy, photo-aging and sometimes skin tumor. To investigate the photo-protective effects of APB-01 (Amore-<br/> Pacific Beauty-01, the mixture of Jaummi-dan and Fujiflavone P10) on UV-induced skin damage, forty of SKH hairless female mice were orally administered with APB-01 or saline fifth a week, and irradiated with UV third a week for up to ten weeks. We examined the relationship between visible changes and skin damage in the dermis and epidermis. In the APB-01 treated group, a better skin<br/> and less wrinkles formation were observed when compared to the UV control group. This results demonstrated that oral administration of APB-01 seems to have photo-protective effects on UV-induced<br/> skin damage of hairless mice due to an inhibitory effect on collagen breakdown, and the model using hairless mice is very useful to investigate the efficacy of functional beauty foods.

While use of mass rearing systems improved poultry production, chances of exposing to contagious diseases have been increased, making flocks more vulnerable to diseases. Diseases of interest which affects egg production adversely include Low pathogenic avian influenza (LPAI), Infectious bronchitis (IB), Avian meta-pneumoviral infection (aMPV) and Egg drop syndrome’76 (EDS’76). This report collected and analyzed 5,385 serum samples, which were collected from 1,330 different chicken flock, provided by Chungbuk National University, Avian Disease Laboratory at 2009. Serums were analyzed based on rearing stages; 0∼1.3weeks (wks) (maternal antibody period), >1.3∼3 wks (starting period), >3∼10 wks (growing period), >10∼22 wks (developing period), >22∼40 wks (peak laying period), >40∼60 wks (late laying period) and over 60 wks (post-molting period). Results showed the 99.7% of the tested flocks were immunized against ND and73.8%, 97.1%, 78,2% and 78% of the flocks were immunized against other 4 agents (LPAI, IB, EDS’76, aMPV). Maternal antibody was transferred to enough quantity for NDV. Generally, antibody titers which were developed at 22 weeks were stabilized permanently for life. In case of IB and aMPV, infection titer emerged as early as 10 weeks and the titer was increased from 99.4% to 100% for life. EDS76 showed increase in titers, reflecting decreased frequency of vaccination programs. Overall, this study displayed general trends of major viral disease in layers, but considering the trend of development of preventive measures and evolution of pathogens, conducting serological surveys on a regular basis is important.

This paper estimates the characteristics of employment adjustment methods and the employment adjustment speed in manufacturing firms over the 30 years since the Yen’s appreciation depression (Endaka Fukyo) and examine systems and legal regulations of employment protection in Japan. The results of this study are summarized as follows: Japanese companies take several steps when they adjust employment due to economic conditions. First, they carry out the employment adjustment by the reduction of overtime work, and then, the workers’ redeployment and relocation, followed by enforced leave, while the dismissal of workers is the last measure that Japanese companies turn to. The results by empirical analysis using time-series data support that: (ⅰ) the employment adjustment speed based on working hours, is higher than that of employee numbers; (ⅱ) we can’t conclude that a change in employment structure by the increase of non-regular employment, raises the employment adjustment speed; (ⅲ) the working hours are adjusted based on the fluctuation of production, but the adjustment of employee numbers, is small and shows a lag. The features in the Japanese employment adjustment; such as long working hours and low dismissal practice, are supported by a low premium rate for overtime work, employment adjustment subsidies, and law and precedent to protect employees against dismissal.

This paper studies the female labor supply in Japan, in particular, confirms the characteristics on structure of female labor employment for the past 60 years and does the Time-Series analysis of supply determinants. In Japan, female employee supply has been increased by the demand side factor, a supply side factor, and the spread of legal systems, but more than half of female employee works as a temporary worker, and its rate is increasing. This paper performs the time-series analysis using the monthly data of approximately 40 years from 1972 to 2010, and confirms the determinants of female labor supply in Japan. The female employee rate and female labor force participation rate are used as dependent variables, and the effects of each variable are compared.

Buckwheat sprout is used as vegetable, and also flour for making noodles, and so on. Currently, information about tissue culture in buckwheat is limited and restricted to micropropagation. We carried out somatic embryogenesis and plant regeneration using hypocotyl segments as explant of the cultivated buckwheat species Fagopyrum esculentum, differs from existing studies in the growth regulator combinations used. Maximum callus regeneration was induced on MS medium containing 2,4-D(2.0 mg/L) and benzylaminopurine BAP (1.0 mg/L) and 3% sucrose. Friable callus was transferred to solidified MS media containing BAP (1.0 mg/L) and at various concentrations for the induction of embryogensis. The optimum concentrations of additives were IAA (2 mg/L), KIN(1.0 mg/L), BAP (1.0 mg/L), and 3% (w/v) sucrose. Only 2,4-D did not show any significant effect on callus induction or embryogenesis. Regeneration of embryonic callus varied from 5 % to 20%. Whole plants were obtained at high frequencies when the embryogenic calluses with somatic embryos and organized shoot primordia were transferred to MS media with 3% sucrose. Regenerated plants after acclimation will transfer to green house. The main objective of this research was to develop a efficient protocol for plant regeneration for common buckwheat, and to apply in future for genetic transformation.
