  • Fourteen Bacillus thuringiensis isolates having both insecticidal activity and in vitro antifungal activity were selected and tested for in vivo antifungal activity against tomato late blight, wheat leaf rust, tomato gray mold, and barley powdery mildew in growth chambers. All the isolates represented more than 70% disease control efficacy against at least one of four plant diseases. Specifically, 12 isolates exhibited strong control activity against barley powdery mildew. Under glasshouse conditions, four (50-02, 52-08, 52-16, and 52-18) of the isolates also displayed potent control efficacy against cucumber powdery mildew. To our knowledge, this is the first report of B. thuringiensis isolates that have disease control efficacy against powdery mildew of barley and cucumber as well as insecticidal activity.

  • Involvement of ethylene and Ca2+ on the induction of phenylalanine ammonia-lyase (PAL) was investigated in Daucus carota L. suspension culture system. Ethylene production started to increase about 3 h after glucan treatment. And the maximal induction of ethylene was preceded by PAL induction by 30 min. After the treatment of ethrel, PAL activity was increased. When cells were treated with glucan and Co2+, PAL activity was simultaneously reduced. Ethylene production was reduced dramatically in calcium-free medium, even though glucan was treated. PAL activity and ethylene producton was inhibited conspicuously when ethylene glycolbis($\beta$-aminoethyl ether) N,N,N',N'-tetraacetic acid (EGTA) was treated with glucan. Verapamil and trifluoperazine also inhibited PAL activity. When cells were treated with calcium ionophore A23187, PAL activity was increased in nontreated medium. We report here PAl activity is increased in related to ethylene production and involvement of Ca2+ in glucan-treated carrot suspension cells.

  • Purpose: This study aimed to describe a non-face-to-face dementia prevention and physical activity program in small rural villages during the COVID-19 pandemic. Methods: The study used a case report provided by a primary healthcare post in Gyeonggi-do in 2020. Results: The program was "From head to toe, stay healthy", which was largely divided into dementia prevention ("Dementia Zero Zone") and physical activity ("The less fat, The healthier body"). Five elderly people aged 75 and over participated for preventing dementia, and 13 residents joined the health promoting programs over 80 times in total. This program was designed one-to-one customized and person-centered program, including counseling, education, and health services. The program participants responded that the amount of physical activities was increased even under strict social distancing and they felt less isolated and less depressed. Moreover, the number of screening for dementia was increased with this program. Conclusion: This case has shown the applicability of a new approach to sustain health promotion programs in the context of limited interaction with rural nurses. Under the challenging environment that requires adaptation to information and communication technologies (ICTs), it will be necessary to solve not only technical problems but also digital literacy issues of rural residents.

  • We report on some of the preliminary results of the physiological responses resulting from vehicular speed changes. Healthy human subjects (n=5) were studied for the experiments. We measured the physiological responses of the subjects such as Heart Rate Variability (HRV), Galvanic Skin Response (GSR), and skin temperature for day and night vehicular speed change experiments, respectively. Before and after the tasks, we carried out a self-report for acquiring correlation with experiment results. Mean heart rate variability (HRV) and amplitude of GSR and skin temperature were calculated for 3 minutes duration in each state. The analysis of the physiological measures of ANS activity revealed that vehicle speed change-based affective state evoked arousal response pattern featured by HR acceleration, decrease of skin temperature, and increase of GSR amplitude. The obtained results show that despite some differences observed between each state, overall physiological responses show that the activity of the sympathetic nervous system increases as a result of the increase of speed.

  • Hemophilia A is the most common congenital bleeding disorder, which is sex-linked disease, caused by a deficiency of clotting factor VIII. We experienced a case of alveolorrhaphy using iliac bone graft under general anesthesia for the correction of bilateral cleft alveolus in 10-year-old boy with hemophilia A. Factor VIII activity in this patient was 0.7%, on the severely deficient level, and aPTT was 100 seconds. Just before operation, he received 1,750 units of factor VIII intravenously for loading dose. After we confirmed his factor VIII activity improved to 95% and aPTT to 38.4 seconds, operation was begun. No more transfusion was needed during the operation. In his postoperative care, he received 50 units/kg a 12 hours for 3 days and 30 units/kg a 12 days for 2 days. His factor VIII activity was maintained at 57-139% during his hospitalization. He was discharged without any anesthetic complication. So we report this successful case of anesthetic management for the oral surgery in a child with hemophilia A.

  • Purpose: This study was designed to find the correlations between physical activity and insulin resistance of the middle-aged adults. Methods: One hundred thirty one subjects participated in this study were age 40-60 from Y university's center for physical exercise in W city. The data were collected from August 5 to October 5, 2009. To measure physical activity, the contracted Korean version of the Self-Report of Physical Activity Questionnaires of IPAQ was used. Insulin resistance was measured using fasting glucose levels, serum insulin levels, and HOMA method (serum insulin${\times}$fasting glucose/22.5). Results: The continuous physical activity overall in this study was on average $1,792.30{\pm}2,216.81$ MET (min/week), and as a result of categorical classification: no activity was 66 subjects (50.4%); minimum activity, 41 (31.3%); and health-improving activity, 24 (18.3%), respectively. The overall degree of insulin resistance in these subjects was $2.20{\pm}2.62$(0.28-12.74). There was negative correlation between moderate intensity activity and insulin resistance (r= -.189, p<.05). Conclusion: These results revealed that promoting moderate-intensity physical activity is important in preventing and improving insulin resistance and possibly other metabolic risk factors in the middle-aged adults.

  • Capsuloligamentous injury at the first metatarsophalangeal (MTP) joint is a common traumatic injury during physical activity, particularly on artificial turf. Mechanism of injury include excessive flexion, extension, or valgus stress. We report a non-operatively treated capsuloligamentous injury at the first MTP joint, which did not occur traumatically but developed by a stress-related mechanism in a collegiate rower.

  • The root of Pseudostellaria heterophylla Pax et Hoffm. (Caryophyllaceae) is a herbal medicine called Taejasam(太子蔘) and used as a good tonic in China that strengthens the functions of the lung and the stomach like Ginseng in Korea. It has been known to have the antitussive activity for tuberculosis, appetizing effect and antifatigue activity, and so on. Especially it has been known to generate body fluids for the severe thirst and the shortage of water in body after a febrile disease for a long time. Recently some components of cyclic peptides, pseudostellarins A,B,C,D,E,F,G, that inhibit the activity of tyrosinase, were separated from this root. In this report several biological activities including acute toxicity, analgesic activity, antifatigue activity, bile juice increasing activity, hepatoprotective activity and antiinflammatory activity were investigated. These results showed as such; $LD_{50}$ of methanol extracts was above 10,000 mg/kg. The analgesic effect was revealed in the writhing test using rats. The BuOH fractions showed a prominent antifatigue effect against immobilized stress, significant hepatoprotective activities against $CCl_4$ intoxication and inhibitory effect on carrageenin-induced edema in rat's paw.

  • Recombinant light chain of Clostridium botulinum neurotoxin type B stimulated transglutaminase activity in a dose dependent manner, Compared to native toxin, recombinant light chain showed av greater stimulatory effect on transglutaminase activity. Zn-chelating agents, inhibiting the proteolytic activity of the clostridial toxins, did not interfere with this stimulation. These results suggest that the light chain plays a major stimulatory role, which is not due to its metallopeptidase activity, but is possibly due to specific interaction with transglutaminase. More importantly, this report provides a new insight into the intracellular action of C. botulinum neurotoxins.
