This neurological damage accelerates the infection reaction of cells and apoptosis at the time of reperfusion after ischemia occurs. BCL-2/BCL-2 allogeneic begeminum has a function of suppressing the apoptosis of cells, and thus it is inferred that the susceptibility of cells to apoptosis is determined by the amount of allogeneic begeminum present which is determined based on the amount of BAX. Ischemia was induced in SD mice by occluding the common carotid artery for 5 minutes, after which blood was re-perfused. NEES was applied to acupuncture points, at 12, 24, and 48 hours post-ischemia on the joksamri, Hapgok. Protein expression was investigated through BAX antibody immuno-reactive cells in the cerebral nerve cells and Western blotting. The results were as follows: In the present study as well, as a result of observation of the change in the number of the BAX reaction cells after the inducement of GI, there was the aspect of most of the BAX reaction cells being observed in the corpus striatum area of the GI group 24 hours after the inducement of ischemia. This revealed the same results as those of previous studies in which the change in the number of BAX reaction cells occurred in all areas while ischemia was in progress. The change in the expression of BAX protein after 24 hours showed that there was a very significant reduction in the NEES group compared to the GI group (p<.01). As a result, a greatest amount of change in the number of BAX immunoreactive cells related to apoptosis 24 hours after ischemia appeared in the NEES group. This study that ischemia increases the expression of BAX that induces apoptosis. Thus, it is determined that ischemia is the main cause of the apoptosis of neurons, and this study reveals that low frequency needle electrode electrical stimulation has the effect of blocking the apoptosis of neurons by reducing protein related to the apoptosis of cells that has increased after ischemia has occurred.

Insect is an important player in the ecosystem as a prey for animals. Moreover, they are a valuable candidate food source for rearing animal. Tenebrio molitor (Coeloptera: Tenebrionidae) larvae are known as a good food source with high protein, unsaturated fatty acid, minerals. Therefore, it has strong potential to substitute the conventional meat consumption. To utilize T. molitor as a feed, the standard mass-rearing protocol is required. To make standard mass-rearing protocol, we tested different temperature(17.5, 20, 22.5, 25, 27.5 and 30°C) conditions for egg, larvae, pupae and adult T. molitor to identify the optimal rearing condition. Hatching was occurred within 15~32.5°C range. However, 17.5~27.5°C was required to get more than 70 % hatching rete. When the eggs were treated in 22.5~27.5°C, all eggs were hatched within 10 days. As larval development, shorter developmental period, higher pupation and eclosion rates were observed within 25~27.5°C temperature range. In addition, we compared the number of egg, oviposition duration and time required to start egg-laying. The minimum egg-laying(258.40±10.86) was observed at 17.5°C, but the maximum(749.10±7.45) was at 27.5°C. The maximum oviposition duration (137.00±12.73 day (mean±S.D.)) was achieved at 27.5°C, but the minimum (87.50±3.54 day (mean±S.D.)) was at 30°C. The time required to start egg-laying was less than 10 days at 17.5, 27.5, and 30°C. To consider all the factors, we concluded that the optimal temperature is 27.5 °C.

This study was conducted to examine the occurrence characteristics of pine trees infected by pine wood nematode in Gyeongsangbuk-do, Korea. Based on the GPS coordinate data of the infected trees at Yeongdeok-gun from 2013 to 2014 and at Andong-si in 2014, nearest neighbor analysis was conducted to analyze nearest distance between the infected trees. And the influence of geographical factors such as altitude, slope, and the distance from the road on the position of infected trees were identified. Our results showed that over 60% of the newly infected trees were found within 50m of the trees infected in previous year. Over 70% of infected trees occurred below 100m altitude in Yoeongdeok-gun whereas less 32% of total pine trees distributed below the altitude. 98% of the infected trees and 74% of total pine trees in Andong-si were found between 150 and 300m altitude, and altitudinal distribution of the infected trees was similar to that of pine forests. Only less 5% of infected trees found in the forests located below 5 degree of slope in Yeongdeok-gun whereas 18% of total pine trees existed in the areas. Over 50% of infected trees in the forests located from 10 to 20 degree of slope, and 47% of total pine trees were found in the forests located from 5 to 15 degree of slope. Most infected trees and total pine trees were found in the forests located below 15 degree of slope in Andong-si. Over 80% of the infected trees occurred within 1km of road in both study areas.

Subcutaneous emphysema is a rare but serious side effect of dental and oral surgery procedures. The condition is characterized by air being forced underneath the tissue, leading to swelling, crepitus on palpation, and with potential to spread along the fascial planes to the periorbital, mediastinal, pericardial, and/or thoracic spaces. A wide range of causes have been documented for the origin of subcutaneous emphysema during dental treatment including: crown preparations, other operative procedures, endodontic therapy, extractions, as well as oral surgery procedures. The patient was a 58-year-old woman who presented to the Seoul Saint mary’s hospital emergency department with a chief complaint of facial edema, dyspnea and chest discomfort after periodontal treatment using an air-flow equipment in local dental clinic. During treatment in the emergency department, oxygen therapy and intravenous injection of steroid and anti-histamine was done. it was noted that the patient had pain and swelling on left lower molar region, pus discharging on same site. Severe edema was observed on periorbital region to neck with heatness. An audible crepitus sound was heard during palpation on facial area. Neck CT scan and antibiotic therapy was done, as symptom suggesting dental abscess is observed. 3 hours after injection of antibiotics, the patient’s symptom was relieved, but she felt chest discomfort continuously. CT scan with constrast depicted confluent and extensive soft tissue emphysematous changes involving face and deep neck spaces and pneumomediastinum. The patient was refered to thoracic surgery department, oxygen therapy was decided continuously. After 10 hours, patient’s chief complaint was resolved, and discharged. After 1 week, all symptom was disappear and follow-up neck CT scan finding was disappearance of edema and pnuemomediastinum. We report a case of cervical subcutaneous emphysema and pneumomediastinum occurring after periodontal treatment using an air-flow equipment and case on the diagnosis and treatment of subcutaneous emphysema and pneumomediastinum, along with a review of the literature.

‘Well-being’ is an important trend and issue that requires consumers to be satisfied with various functional fabrics; subsequently, functional fabrics that are highly sensible, functional, and environmentally friendly have a competitive edge (O’Mahony & Braddock, 2002; Hui, Lau & Ng, 2004). Recent interest in environmental protection due to global warming has led to various energy reduction campaigns. Fabric research has focused on developing cool summer fabrics and warm winter fabrics. The selection of a correct textile material is important to form a pleasant clothing climate. New fabric development requires new measurement methods. Warm/cool touch is a major factor that influences thermal clothing comfort. Current measurements of warm/cool touch is mainly assessed by Q-max using Thermo-LaboⅡ. The potential of using an infrared thermography camera (widely used because of its relatively cheap price) on warm/cool touch research has increased because it can visually show changes in clothing surface temperature. Skin temperature is a factor that influences heat exchange between the body and environment. It also indicates the effectiveness of the heat transfer process. It is an important standard to evaluate thermal comfort in thermal physiology. The techniques to measure skin temperature have been investigated to find more accurate data (Min, Chung, Sung, Jeon, & Kim, 2001). A thermometer is generally used to measure body temperature; however, there are some difficulties to accurately measure skin temperature using a thermometer. First, skin temperature was determined by only a few points on the body. Second, heat occurs during exercising due to fabric and thermometer friction that creates difficulties for the accurate measurement of skin temperature. A previous study by Choi & Lee (2008) indicated that it would be possible to evaluate the thermal properties of clothing using infrared thermal images. This study used a garment with different triacetate and PET high absorbance quick dry filament blending ratios and chose three healthy female subjects in their twenties to evaluate wear comfort sensations. They walked at 3.3 km/h for 20 minutes under conditions of 29±2℃ and 75±5% R.H. Subjective assessments of wear coolness, microclimate, and the thermogram image under the clothing were measured before and after exercising. We compared the results of the microclimate and subjective assessments with the results of the thermogram analyses. Clothing, high blended with triacetate, had a small average temperature difference as indicated by infrared thermal image. This result corresponded to subjective thermal sensation, microclimate humidity, and subjective wear comfort.

Clothing comfort indicates the comfortableness of the in varying environmental situations while wearing specific clothing. Various factors affect clothing comfort such as skin moisture perception and heat transmission characteristics via clothing; however, cool and warm touch are the most important factors (Kwon, Yi, & Sung,1999; Hong & Kim, 2007; Manshahia & Das, 2014). The thermal comfort of clothing is perceived through sensory receptors on the skin surface and is highly related to a cool and warm touch. An infrared thermography camera detects infrared-ray-form energy, a type of electromagnetic wave radiated from the subject's surface that assesses the intensity of radiant heat. The changing intensity then presents a real-time infrared thermal distribution using various colors. The advantages of an infrared thermography camera are the ability to use a non-contacting method to measure temperature distribution and analyze temperatures. Therefore, an infrared thermography camera is widely used in material characteristic assessment, boiler heat distribution analysis, process control, and building insulation assessments that indicate system deficiencies. This technique has also recently been used in human-body-related temperature measurements with potential for application to medical fields that include breast cancer examinations, joint muscle disorders, and body reactions under specific conditions. The most significant advantage of infrared thermography cameras to evaluate heat conductivity according to wearing conditions are its inexpensive price, ease-of-use and visual representation of surface heat dispersion on clothing that maintains body temperature and helps dissipate sweat(B. Lee, Hong, & Y. Lee, 2010; Lee, K. Hong, & S. A. Hong, 2007). This technique is also used in a quantitative analysis of thermal sensation when wearing clothes (Choi & Lee, 2008). This study helps develop a method to evaluate the warm feeling of fabrics using an infrared thermal image of a small test specimen. An infrared thermal image helped develop5 types of fabrics for heat storage fabric; consequently, the average temperature difference of the human palm when the fabric is on or off was used for the scale of the fabrics’ warm feeling. The relationshipbetween this average temperature difference on the palm surface Qmax, and warmth keep-ability rate was examined. Fabric had a significant average temperature difference in the infrared thermal image with alow Qmax value and was evaluated with high values in the warmth keep-ability rate. Infrared thermography camera was shown to be effective in the fabric's warm feeling evaluation.

The purpose of the present study is to provide exercises, together with music, that are helpful for elderly people’s balancing ability, and to determine their effects in order to provide data for the promotion of elderly persons’health. Thirty elderly persons were randomly assigned to a balance training group(BTG) of 15 subjects, or a music and balance training group (music therapy + balance training [MTBTG]) of 15 subjects; intervention was implemented three times per week for six weeks. To measure the changes in their balancing ability before and after the experiment, the limit of stability, the“Timed Up and Go”(TUG) test, and the Berg Balance Scale (BBS) were measured. Changes in the limit of stability before and after the experiment were shown to be significant in both the BTG and the MTBTG. Changes in the limit of stability of the right side before and after the experiment showed statistically significant differences between the BTG and the MTBTG. Changes in the TUG test and the BBS before and after the experiment were shown to be statistically significant in both the BTG and the MTBTG. The application of music during balance training thus is considered to have a positive effect on elderly persons’balancing ability.

The objectives of this study were to evaluate the antimicrobial effects of ε-poly-L-lysine mixture (EPM) on cheon-ggukjang and to determine the optimal mixing ratio in cheonggukjang. Increasing the EPM up to 2% decreased via-ble cell counts at both 15oC and 30oC storage. The pH of cheonggukjang without EPM increased slowly over thestorage periods, but cheonggukjang with EPM showed a slight increasing tendency, with the highest pH at 2% EPM.The sensory scores, such as texture and flavor, were highest in samples containing 2% EPM; however, overall pref-erence was not significantly different when compared to the control. For the optimum cheonggukjang processingconditions, 13 experimental points were selected. Soybean and EPM were chosen as independent variables. Viablecell count, pH, texture, and overall preference were measured. The optimum formulation of cheonggukjang usingthe numerical analysis was found to be 98.52% soybean and 1.48% EPM, resulting in a 0.722 desirability value.

The cerebellum is known to control balance, equilibrium, and muscle tone. If the cerebellum becomes damaged, the body is unable to retain its balancing functions or involuntary muscle movement. This is why, in stroke patients, there is a high risk of functional disability, as well as a myriad of other disabilities secondary to stroke. Ischemia was induced in SD mice by occluding the common carotid artery for 5 minutes, after which blood was reperfused. Needle electrode electrical stimulation(NEES) was applied to acupuncture points, at 12, 24, and 48 hours post-ischemia on the joksamri. Protein expression was investigated through caspase-3 antibody immuno-reactive cells in the cerebral nerve cells and Western blotting. The results were as follows: The number of caspase-3 reactive cells in the corpus cerebellum 12 and 24 hours post-ischemia was significantly (p<.05) smaller in the NEES group compared to the GI group. caspase-3 expression 12 and 24 hours post-ischemia was significantly(p<.05) smaller in the NEES group compared to the GI group. Based on these results, NEES seems to have a significant effect on Caspase-3 in the cerebellum in an ischemic state at 12 and 24 hours post ischemia, NEES delays the occurrence of early stage apoptosis-inducing Caspase-3, delaying and inhibiting apoptosis. Further systematic studies will have to be conducted in relation to the application of this study’s results on stroke patients.

The goal of this study was to assess the effect of a group exercise program on cognitive function of elderly people. Subjects were chosen to be elders with dementia having minor to moderate degrees of cognitive function. Study was started out by randomly dividing the 16 subjects into two groups, each with 8 people; the group exercise group and the control group. The group exercise group performed 8 weeks of group exercise program and general physiotherapy while the control group only performed general physiotherapy. Cognitive function was measured by Korean version mini-mental state examination. The study group's attention and calculation statistically significantly improved but the control group saw no statistically significant change. The group exercise program affected improvement in cognitive function of elderly people with dementia and in particular, was effective for enhancing their attention and calculation.

Insect pollinators of the endanger orchid Cypripedium japonicum were surveyed and identified during two years, as a part of a conservation project of the orchid at Jukyeup-san and Hwaak-san (Mt.), South Korea. In total 40 individuals of 16 species in 4 families were identified. The dominant family was Halictidae, and Lasioglossum exiliceps Vachal visited the most frequently C. japonicum during the surveys. The average visiting frequency was 2.5 individuals per hour and the highest 4.3, from 12:00 – 13:00 in a day. After 15:00 insects did not visit the flowers at all. However, all of the visiting insects were found to not carry a pollinium or pollens of the orchard on their bodies; pollen carryover by any of the visiting insects did not occur at all. The orchid seems to require certain pollinators in particular body thickness due to its unique pollination mechanism. The orchid has two exit route openings, around 1 cm in diametre, where the entrapped insects can exit and an anther is situated just in front of each opening. It was inferred that a pollen carrier should be around 1 cm in body thickness. Therefore, the candidate species as the proper pollen carriers can be Tetralonia nipponensis Perez, Xylocopa appendiculata circumvolans Smith and Bombus consobrinus Dahlbom among the surveyed visitors.

Materials are limited for pest control and chemical pesticides are prohibited in organic farming. Thus, the concept of pest control may not be effective for pest management in organic farm. As an alternative approach, landscape management is potentially effective and useful approach for preventing pathogen and insect pests in organic farm. It is needed to develop best practices utilizing functional biodiversity for pest management through landscape management. For this purpose, we investigated the effect of companion plants on species richness of insect pests and natural enemies in the field border area and in the crop plants (rice and soybean). In rice paddy fields, Lysimachiae foenum-graecum, Saururus chinensis were selected as effective companion plants on the paddy field levee for conserving Arachnidae as natural enemy and density suppression of insect pest such as Lissorphoptrus oryzophilus, Riptortus clavatus. As a result, damage rate of rice plant by insect pests was significantly lower (2.5%) and yield rate of healthy grains was significantly higher (8.7%) than control. In soybean fields, Marigold plants such as Tagetes patula, T. officinalis, increased Arthropod species richness and ratio of natural enemy group, and decreased ratio of insect pest group. As a result, yield (weight of 100 seeds) of healthy soybean was significantly increased (2.5%) than control. The 2nd infection rate from damage by R. clavatus was significantly lower in the treated plot than that in control. Thus, yield rates of healthy soybean in the control and the companion plant-treated plot were 79.0% and 84.3%, respectively, compared to conventional farming using chemical pesticides. Therefore, use of companion plants on field border was an effective practices for preventing pest insects and increasing yield in organic farming.

The fact that flip-flops, one of many different types of unstable shoes, are light and relatively easy to put on, accounts for their popularity among people. But because flip-flops rely heavily on the support of a single thong between your first and second toes, they impose a huge amount of pressure onto lower leg. Thus in the following experiment we tried to examine the different effects of flip-flops and running shoes in terms of their effect on muscle activity and fatigue of tibialis anterior and gastrocnemius during walking. In order to measure an electromyogram we used Free EMG system. 10 men and 10 women in running shoes ran on treadmills for 15 minutes at 4.8km/h, 2 days later the same experiment was carried out, but this time, in flip-flops. p value turned out to be greater than .05 and thus there was no considerable difference between the effects of flip-flops and running shoes on muscle activity and fatigue during walking. Therefore we conclude that despite the fact that flip-flops are considered unstable, their effects on muscle activity and fatigue of tibialis anterior and gastrocnemius are negligible.

Recent changes in the global climate environment have resulted in a wide variety of climaterelated disasters, including floods, tidal waves, forest fires, droughts, etc. In addition, global warming raises the risk of food poisoning, which may increase the spread of infectious diseases and alter their structure. Under these circumstances, it is necessary to provide accurate and persuasive information to consumers so that they can be fully informed of climate change and alter their behavior accordingly. Therefore, the intention of this study was to develop posters and contents for image production related to climate change and food safety. The posters are focused on consumers with headings such as 『Climate Change Threatening Food Safety』,『Earth getting warmer, your dining table is at risk』, 『Warning signs ahead for the globe』, and more. Five poster drafts were selected initially, and a survey was carried out amongst 1,087 people regarding their preferences, with the most preferred design chosen. The images related to climate change and food safety defined climate change, how it relates to food safety, the risks it poses to the food industry, and lastly, how the public can respond in the future. Therefore, to further communicate the importance of food safety to consumers, the development, education, and promotion of these contents should be performed to provide safety information to consumers in the future.
