In order to replace sardine baits for octopus pot, an efficacy experiment to lure with alternative bait (fermented skate or chicken skin in artificial crab or northern clam) pots and sardine pot were conducted in a circular water tank. The soaking time of the sardine bait was divided into two categories: six days or less and seven days or more. The behavioral response of octopus to the artificial bait pots and sardine pot were investigated. In the comparison of the luring effects between pots with fermented skate inside artificial crab or northern clam and sardine pot, the pot with artificial crab + fermented skate had better results than the other pots in the section distribution (31.6%) and the number of times the pot was entered into (20.0%) (p > 0.05). In the comparison of the luring effects between pots with chicken skin inside artificial crab or northern clam and sardine pot, the pot with northern clam + chicken skin had better results than the other pots in the section distribution (22.6%) and number of times the pot was entered into (55.6%) (p < 0.05). The results were also better compared to those of pot with artificial crab + fermented skate. From these results, it seems that in the luring effect aspect, sardine bait can be replaced with artificial bait consisting of chicken skin inside northern clam.

Background: Postural tachycardia syndrome (POTS) refers to the presence of orthostatic intolerance symptoms associated with a heart rate increment of greater than 30 beats/min, usually up to 120 beats/min, on head-up tilt test. Symptoms related to POTS are usually light-headedness, palpitations and tremor, but syncope can also occur. The pathophysiology of POTS is heterogeneous and its prognosis is uncertain. Methods: We prospectively evaluated patients who met the criteria for POTS, at baseline and follow-up, using composite autonomic symptom scores and autonomic tests to assess the autonomic function. We compared the clinical and autonomic test results between baseline and follow-up. Results: Sixty-eight patients met the inclusion criteria for POTS and forty-five patients were ultimately followed up for at least 1 year after baseline. The patients were predominantly young females (84%), with a mean age of 21 years. Most patients showed improved orthostatic symptoms and more than a quarter of patients had no longer met the criteria for POTS at follow-up. Conclusions: Most patients had a benign outcome in that they could resume their daily activities without great limitations. Our results demonstrated a relatively favorable prognosis in most patients with POTS.

Traditional sea Eel pots can be divided into two groups such as bamboo and plastic pots, however they are nearly same in a shape with one entrance and fishing efficiency, except their materials. Very few yet have been studied on their catching methods or catching mechanisms at the view point of behavior. Accordingly, we have designed tubular pots in order to fill up faults of traditional fishing gear construction and behaviors of sea eel. The suitable tubular pots was decided by comparative experiments in the water tank and the fishing efficiency was compared through the field experiments. The results obtained are as follows : 1. The differences between traditional plastic pots and improved tubular pots are firstly two entrances in both ends of tube without holes, secondly flapper nets are fixed at the end of each cone, and thirdly a bait bag is fixed at the center of pot. 2. The standard size of the suitable tubular pot is: $$Tube\;:\;\phi\;12\~13{\times}L80\;cm$$, $$Cone\;:\;Inside\;ring\;\phi6{\times}D5\;cm$$, Flapper : L10 cm. 3. The fishing efficiency of tubular rots is 2.3 times better than that of plastic pots.

Purpose: This study sought to identify the utilization and confidence in assistive technology (AT) for pediatric physical therapists (PPTs) and pediatric occupational therapists (POTs) for the purpose of improving the utilization of AT in clinics. Methods: The subjects of this study were 167 therapists (98 PPTs and 69 POTs) who work at general hospitals, welfare centers, facilities for the disabled, and special education schools in Seoul and Gyeonggi province. The frequency analysis and chi-squared test were used. Results: This study found that both PPTs and POTs recognize that AT benefits infants with disabilities; however, they show low confidence in using AT. Applications of AT are concentrated on wheelchairs for mobility and assistance with seating position, with orthotics/prosthetics for both purposes. POTs were found to use a wider variety of AT devices. While both PPTs and POTs frequently select/recommend devices, both groups are less involved with delivery methods, manufacture of devices, and education on AT use. Conclusion: These findings show the actual conditions of utilization and confidence in AT of PPTs and POTs deeply involved with AT, and emphasize that AT training is essential for pediatric treatment by comparing domestic and foreign studies.

The purpose of this study was to develop wood pots for create Optimum environment of plant growth using unused wood. to prove this, we examined the effects of cycle of water supply and nutrient concentration in wood pots on plant germination rate and growth factors (leaf number, stem diameter and length). The results are as follows. 1) The growth rate was higher at once of 2 days watering period. This suggests that the growth of the plants was better than that of the less water because the larch pots itself has the water retention capacity inside. 2) Germination rate and growth rate were better than other treatment groups when the concentration of nutrient solution was 0.5%. 3) Nitrogen, available phosphoric acid, and potassium showed higher contents than the nutrient - treated soil at 0.5% concentration of nutrient solution. This indicates that the nutrient solution absorbed from the larch affected the soil and plant growth in the inside.

In order to find out the most favorable shape and structure of pot for crab, Charybdis japonica Edwards, the common box type and cylinder type of net pots with two entrances, and the modified cone type and box type of net ones with four were prepared respectively. Then, the ability of the above pots attracting the crab into them and their catches were investigated through tank and field experiments. The attracting ability was higher in pots with four entrances than those with two. In case of two entrance pots, the ability was a little higher in the cylinder type than in the box type. But in four entrance pots, the box type yielded a little higher ability than the cone type. The catches were also arranged by the pots in almost same order with the attracting ability. But, it was only added to the arrangement that the cone type with four entrances had no significant difference of catch with the cylinder type with two entrances. Thus, the most favorable pot for the crab was concluded to be the box type with four entrances.

PURPOSE: This study was designed to evaluate the current state of training in assistive technology(AT) for pediatric physical therapists(PPTs) and pediatric occupational therapists(POTs), in addition, investigate therapists' preferred training methods and contents. The eventual purpose was to suggest the essential fundamental factors to adapt the assistive technology in clinics. METHODS: The subject of this study were 167 therapists(98 PPTs and 69 POTs) who work at general hospitals, welfare center, facilities for the disabled, and special education school in Seoul and Gyeonggi province. Frequency analysis and Chi-squared test were used. RESULTS: Significant numbers of PPTs(66 therapists, 67.3%) and POTs(50 therapists, 72.5%) answered that they had received training in AT. More than 48% answered no training experience or low adequacy in each classification scheme for questions. The most difficulty in the training was indicated by lack of education opportunity(90 therapists, 53.9%). The most required device training was seating and position device training(43 therapists, 21.9%) for PPTs and orthosis and prosthesis device training(29 therapists, 21.0%) for POTs. In assistive technology service, PPTs needed evaluation to AT device training(69 therapists, 35.2%) and POTs needed evaluation to disabilities for AT training(41 therapists, 29.7%). Both therapists answered that the most effective training is continuous education(52 therapists, 31.1%) and college education(48 therapists, 28.7%). CONCLUSION: Our findings indicate that PPTs and POTs need more opportunities for training in AT. For effective clinical app lication of AT, there should be continuous education such as on-the-job training, mentoring program, technical manual, and college education.

Land application of treated palm oil mill effluent (TPOME) could be used as an alternative tertiary wastewater treatment process. However, phenolic compounds in TPOME might be leached to the environment. This study investigated the ability of grasses on reducing phenolic compounds in the leachate after TPOME application. Several pasture grasses in soil pots were compared after irrigating with TPOME from stabilization ponds, which contained 360-630 mg/L phenolic compounds. The number of soil bacteria in planted pots increased over time with the average of $10^8CFU/g$ for mature grasses, while only $10^4-10^6CFU/g$ were found in the unplanted control pots. The leachates from TPOME irrigated grass pots contained lower amounts of phenolic compounds and had lower phytotoxicity than that of control pots. The phenol removal efficiency of grass pots was ranged 67-93% and depended on grass cultivars, initial concentration of phenolic compounds and frequency of irrigations. When compared to water irrigation, TPOME led to an increased phenolic compounds accumulation in grass tissues and decreased biomass of Brachiaria hybrid and Brachiaria humidicola but not Panicum maximum. Consequently, the application of TPOME could be conducted on grassland and the grass species should be selected based on the utilization of grass biomass afterward.
