This study intended to develop wellbeing flowerpots on desk which could create a healthy atmosphere in an office and raise people to joy. The pots developed by Blooming company emphasized a design as touching people's emotion through the organic design of the streamline which is different from the geometric line of the flowerpots manufactured by the company as focusing the design on the utility before. As a result, the pots derived from the organic design concepts could provide happiness or joy to the people, and would be a necessity on the narrow desk along with books or writing materials while working. Therefore, the beautifully streamlined pots are expected to compete with European market as the foreign buyers had a great interest in them at the Fair held in Hong-kong at the end of April, 2008.

Postural orthostatic tachycardia syndrome (POTS) refers to the presence of orthostatic intolerance with a heart rate (HR) increment of 30 beats per minute (bpm) or an absolute HR of 120 bpm or more. There are sporadic reports of the autonomic nervous system dysfunction in migraine and fibromyalgia. We report a case of POTS associated with migraine and fibromyalgia. The patient was managed with multidisciplinary therapies involving medication, education, and exercise which resulted in symptomatic improvement. We also review the literature on the association between POTS, migraine, and fibromyalgia.

In order to develop the substitutive materials for natural baits of swimming crab pots, the fluorescent characteristics of the baits were analyzed, and the preference of fluorescent dyes were investigated by the mean entrapped catch number to the pots through the water tank experiments and fishing experiments. On the investigation of fluorescent characteristics by the 5 kinds of baits, mackerel, krill, manila clam, pig's fat and chicken's head which were used in substitutive baits for test in the UV long wave(365nm) area, it showed clear blue fluorescence in the skin of mackerel, shell of krill, manila clam and bill of chicken's head, and green fluorescence in the mackerel s muscle and internals, and yellow fluorescence in the pig's fat and chicken's head. On the investigation of fluorescent characteristics by the bait cages in the UV short wave(254nm) and long wave(365nm) area, it showed each green, red and blue fluorescence in the cylinderical or hexahedral red plastic bait cages which were painted each green, red and blue fluorescence dyes, but it showed yellowish green flourescence in the cylinderical or hexahedral red plastic bait cage which was painted yellow fluorescent dye. On the preference investigation of the fluorescent dyes of swimming crabs by the 5 kinds of the bait cages which were put the mackerel in the non-fluorescent red plastic cage($RF_N$), red, yellow, green and blue fluorescent plastic cages(RF, YF, GF, BF) each, nonfluorescent red plastic cage($RF_N$) was entrapped mean 2.0(6.7%), but blue fluorescent plastic cage(BF) was mean 5.0(16.7%) and it was more 2.5 times comparing to $RF_N$, and red fluorescent cage(RF) was same level and green fluorescent cage(GF) was 50% of catch number comparing to $RF_N$, and yellow fluorescent cage(YF) was entrapped nothing(F 46.324, P < 0.05). On the investigation of the entrapped catch number to the pots which were put the mackerel in the blue fluorescent hexahedral plastic cage(HP) and blue fluorescent silicon mackerel model cage(SM), HP was mean 3.4(11.3%) and it was a little more comparing to SM which was entrapped mean 3.2(10.7%)(t 0.775, P > 0.05). Fishing experiments on the preference investigation of swimming crabs by the pots which were put in the non-fluorescent red plastic cage($RF_N$) and blue fluorescent plastic cage(BF) were conducted 3 times. Mean catching number and weight of $RF_N$ were 71.7 ind.(18.3%) and 16.9kg(64.3%), and those of BF were 93.0 ind.(23.1%) and 19.8kg(64.5%), respectively.

Purpose: Chronic day-to-day symptoms of orthostatic intolerance are the most notable features of postural orthostatic tachycardia syndrome (POTS). However, we have encountered patients with such symptoms and excessive tachycardia but with no symptoms during the tilt-table test (TTT). We aimed to investigate whether POTS patients with chronic orthostatic intolerance always present orthostatic symptoms during the TTT and analyze the factors underlying symptom manifestation during this test. Methods: We retrospectively examined patients who presented with POTS at the Gyeongsang National University Hospital between 2008 and 2011. Diagnosis of POTS was based on chronic day-to-day orthostatic intolerance symptoms as well as excessive tachycardia during the TTT. The patients were divided two groups depending on the presentation of orthostatic symptoms during the TTT. Clinical data and the results of the TTT were compared between these groups. Results: In 22 patients, 7 patients (31.8%) did not present orthostatic symptoms during the test. Diastolic blood pressure (BP) was significantly lower in the symptom-positive group. The head-up tilt resulted in a significant increase in diastolic BP in the symptom-negative group (P=0.04), while systolic BP had a tendency to decrease in the symptom-positive group (P=0.06). Conclusion: Significant patients with POTS did not present orthostatic symptoms during the TTT despite having chronic daily symptoms. This finding may be important for establishing definitive diagnostic criteria for pediatric POTS. Development of symptoms during TTT might be related to low diastolic BP and abnormal compensatory responses to orthostasis.

현재 대통발과 플라스틱통발의 붕장어 유입성능과 구성재료에 따른 차이 등을 알아보기 위해, 수조실험을 통해 이들 통발에 대한 붕장어의 행동을 조사하여 다음과 같은 결과를 얻었다. 1) 붕장어의 색이행동은 주로 후각에 의존하며, 시각감도는 매우 나쁜 것 같았다. 2) 붕장어의 통발접촉수는 통발투하후 급격히 증가하여 주로 30분 이내에 최대치를 보였다가 차차 감소하였다. 3) 붕장어의 입롱은 통발 투하후 30분 이내에 주로 일어나고, 입롱이 일어나면 통발에의 접촉수가 증가하며, 입롱이 빨리 일어날수록 최대접촉수도 빨리 나타났다. 4) 통발에 접근한 붕장어의 대부분은 미끼가 있는 부분으로 향하여 그곳의 통발외벽을 계속적으로 쪼았고, 입구를 접촉하는 것은 매우 우연적이었다. 5) 붕장어가 통발의 입구를 접촉했을 때는 강한 주촉성을 보이지 않고, 입구를 접촉한 총 회수 중에서 $40\%$ 정도는 입롱을 시도하지 않은 채 도피하였다. 6) 붕장어가 입롱을 시도한 총 회수 중에서 $20\%$는 완전 입롱하였고 나머지 $80\%$는 입롱시도후 도피하였는데, 이러한 불리한 입롱은 주로 입구깔때기의 길이가 긴 것에 기인하는 것 같았다. 7) 통발을 수조바닥에 수평으로 놓은 경우는 미끼의 위치가 통발의 입구쪽에서 꽁무니쪽으로 갈수록 붕장어 유입성능이 나빴다. 8) 통발속에 미끼를 방치하고 통발의 꽁무니쪽을 들어 $30^{\circ}$로 경사시킨 경우는 통발을 수평으로 하여 미끼를 입구쪽에 고정한 경우와 붕장어 유입성능에 대차가 없었으나, 통발의 입구쪽을 들어 $30^{\circ}$로 경사시킨 경우는 유입성능이 매우 나빴다. 9) 대통발과 플라스틱통발을 비교하면, 붕장어의 입롱이 플라스틱통발에서 수분 정도 늦어질 뿐 별다른 차이는 없었다.
