  • Effects of gamma irradiation(2.5∼20kGy) on water absorption property was studied for a local variety of black soybeans. In water absorption patterns of black soybeans, the time to reach a fixed moisture content was reduced depending on the increment of water soaking temperature and irradiation dose. Irradiation at 2.5∼10kGy resulted in the reduction of soaking time of black soybeans by about 1∼3 hours and the increase of hydration capacity by 10∼20%, respectively, compared to the nonirradiated control black soybean. The water uptake rate constant of the irradiated black soybean difinitely increased with the increase of dose levels and water soaking temperature. The activation energy for water absorption and z-value were lower in the irradiated black soybeans than in the nonirradiated control black soybean. The efficacy of water absorption property in the irradiated black soybeans was also recognized after one year of storage at room temperature.

  • In this paper, we propose a new method for multi transmission method of data among near smart devices. Existing methods require the use of an extra application service where the operating system differs between smart devices. In contrast, the proposed method makes use of the smart device's inner speaker and microphone to confirm the transmission signal. Then, real sharing data is transmitted via WiFi or LTE. Therefore, the proposed method overcomes operating system issues with existing methods. Besides, BUMP technology works in a similar way to the method we propose, it only supports one-to-one transmission. To evaluate the efficacy of the new method, we tested one-to-many data transmission in an experiment: the results showed a 96% success rate. As a result, we believe that the proposed method is an effective multi transmission method of data among near smart devices.

  • Vulvodynia is the term used to describe unexplained vulvar pain, sexual dysfunction, and the resultant psychological disability. Vulvodynia may cause physical disabilities, psychological or emotional distress, sexual dysfunction and limitation of daily activities. But its etiologies and treatments are not defined yet. In vulvodynia, the first method of treatment is conservative treatment. surgery is carried out on patients who have failed consevative therapy. In conservative therapy, the rate of improvements is low, 30-40%Surgical procedures are effective in almost patients, but the efficacy is not known in patients with the riskiness. This study is designed to find best way of evaluation about the vulvodynia.

  • For evaluation on effects guiding fasciola prevention of which the specimens collected from 6,011 cows rears at 387 farms in inchon were tested to egg count examination for 4 years(1987-1990), and the questionnaire checked up 181 dairy farms for 2 years (1989-1990). The results were summarized as follows. 1. A yearly variation of fasciola infection rate above 31% were 83% In 1987, 58% in 1988, 25% in 1989, noninfection in 1990. 2. The average concentration in feces of infected dairy cattle was 79.4% below 1-10 eggs for 4 years(1987-1990) 3. In the results of the questionnaire for 2 years(1989-1990) the farmers gradually took interest in fasciola prevention. 4. To re-dose anthelmintics was 75.4% in 1989 and 82.5% in 1990 after 5∼7 months from previous dosage.

  • As the 4th industrial revolution and artificial intelligence technology develop, it is expected that there will be a revolutionary changes in the security robot. However, artificial intelligence system requires enormous hardwares for tremendous computing loads, and there are many challenges that need to be addressed more technologically. This paper introduces precise tracking control technique of autonomous system that need to move repetitive paths for security purpose. The input feedforward signal is generated by using the inverse based iterative learning control theory for the 2 input 2 output nonminimum-phase system which was difficult to overcome by the conventional feedback control system. The simulation results of the input signal generation and precision tracking of given path corresponding to the repetition rate of extreme, such as bandwidth of the system, shows the efficacy of suggested techniques and possibility to be used in military security purposes.

  • This study was performed to assess the efficacy of electrical stimulation for healing of wound in injured tissue, and to provide a baseline for electrical stimulation in the treatment. Although the specific mechanism by electrical stimulation which may promote injured tissue to heal is not known, generally many hypothesis exist such as bactericidal effect, enhanced circulation, stimulation of cellular biosynthesis and replication, and attraction of connective tissues and inflammatory cells The results of this study are as follows : 1. The healing of skin wound was facilitated by electrical stimulation 2. The capacity of collagen synthesis was significantly accelerated by electrical stimulation 3. The application of electrical stimulation to injured tissue may be helpful in augmenting the rate of wound contracture

  • Objectives: To report the efficacy of traditional Korean medicine to an infertile patient who repeatedly failed in vitro fertilization. Methods: The patient was diagnosed with adenomyosis and failed in vitro fertilization 9 times. Her dysmenorrhea and physical symptoms were improved through traditional Korean medicine and she was pregnant with the 10th attempt of in vitro fertilization. She had bleeding during pregnancy due to adenomyosis and took herbal medicines to maintain stable condition. Results: During the treatment period, the uterine thickness due to adenomyosis was reduced and her dysmenorrhea was improved. She was pregnant by in vitro fertilization and gave birth to a healthy child by Caesarean section. Conclusions: This case report shows that traditional Korean medical treatments work to improve the success rate of in vitro fertilization.

  • Esophageal anastomotic leak is the most common and serious complication following esophagectomy. However, the standard treatment for anastomotic leaks remains unclear. Recently, endoscopic vacuum therapy has become an important non-surgical alternative treatment method for patients with esophageal anastomotic leak. This treatment involves the endoscopic placement of a sponge connected to a nasogastric tube into the defect cavity or lumen. Subsequently, continuous negative pressure is delivered to the cavity through the tube. Several studies have reported a treatment success rate of 80% to 100%. In this study, we review the mechanism of action, the method of performing the procedure, its safety and efficacy, and prognostic factors for failure of endoscopic vacuum therapy in the management of patients with anastomotic leak, and on this basis attempted to confirm the possibility of establishing a standardized treatment protocol using endoscopic vacuum therapy.

  • In order to supplement a diagnostic method for detection of infectious cattle to bovine tuberculosis, performed ELISA for detection of antibody to if bovis in serum and milk. The diagnostic efficacy of the established ELISA was compared with test of the tuberculin skin test for bovine tuberculosis. The positive corresponding rate of serum ELISA and tuberculin skin test showed 84.3%, milk ELISA and tuberculin skin test showed 75.0%, milk ELISA and serum ELISA showed 75.0% respectively. Comparison of the serum and milk to tuberculin antibody concentration in tuberculin positive cattle, the milk contained 1/100-1/150 concentration compared serum tuberculin concentration. The established ELISA was considered efficient for detection of antibodies to M bovis in serum and milk.

  • This study aimed to verify the whitening effect of Cordyceps militaris, which is distributed in several countries worldwide, including Korea, Japan, and China, and has various medical effects. To screen the efficacy of C. militaris, the inhibitory activity of tyrosinase, which was 66% at a concentration of 1 mg/mL, was measured. Thereafter, the survival rate of melanoma cells was measured, and cell experiments were conducted at a concentration of 90% or more in which C. militaris was not toxic to cells. After measuring the inhibitory effect of TRP-1, TRP-2, tyrosinase protein, and mRNA expression, which are factors influencing melanin synthesis, C. militaris was found to decrease in all factors, with an expression level that was significantly lower compared to quercetin. This confirmed that C. militaris stimulated with LED has excellent whitening activity and can be used as a functional whitening cosmetics material.
