We investigated the floral resources of the honeybee (Apis mellifera)bypollenDNA metabarcoding as the first step in honeybee conservation. We attempted to identify as many floral resources and as wide resource availability as possible in areas and compared the richness of floral resources between forests and national parks. We found that both forest and national parks can sufficiently support honeybee floral resources; however, national parks were more stable habitats with more complex vegetation structure than those of forests. Also, honeybee’s preferences for floral resources were determined using niche breadth, niche overlap, and network analysis among the floral resources in forest areas. Quercus and Actinidia were the most frequently detected taxa of pollen resources in both forests and national parks by pollen metabarcoding. Even though we anticipated that more various pollen resource taxa would be found in national parks than forests, no differences in the number pollen resource taxa were detected between them. According to the niche overlap analysis result, the honeybee preferred the pollen resources in both forests and national parks, and the co-occurrence pattern analysis of pollen resource taxa in both forests and national parks showed a simple network. Altogether, our findings suggested that DNA metabarcoding of pollen collected by the honeybee can provide useful information on the flowering plants in a given area. As the use of floral pollen resources varies spatially and temporally, periodic monitoring of pollen resources can identify which pollen is required to maintain the health of honeybee colonies.

Animal and human studies indicated that inadequate diet for a prolonged period during pregnancy could injure mother, child, or both. In order to prevent this problem, maternal nutyitional status during pregnancy is very important and the evaluation of nutrition during pregnancy have been preceded by many authors in another countries. In Korea, nutrient intake studies of the pregnant women and nutrition surveys in adult by biochemical method have been performed, but there are no data nutrition surveys of Korean pregnant women have been made by biochemical method. In this regard, an exact biochemical titer of the nutrients and the degree of nutrient deficits in Korean pregnant women are needed. In this study, the mean titer of some nutrients and the degree of nutrient deficits by biochemical method in Korean pregnant women were assessed. The objected materials were consisted of 30 cases which had visited the departmant of Obstetrics & Gynecology, Chung Ang University Hospital for antenatal care(32wk-40wk) from March, 1981 to June, 1981. The cases with twin pregnancy, and the cases complicated with materal chronic wasting disease, diabetes, hydroamniosis, hypertensive disorder in pregnancy were excluded in this study. The results were as follows: 1. Mean titer of 6 hours urine execretion of thiamine, riboflavin and N'-methylniacinamide in Korean pregnant women was 44㎍, 466㎍, and 2.33㎎. 2. Mean titer of serum vitamin A, carotene, vitamin C, total protein, calcium, phosphorus, iron and total lipid was 48.1㎍, 154.7㎍, 0.8㎎, 7.0g, 9.8㎎ 3.5㎎, 93㎍, and 578㎎. 3. Percentage of nutrient deficits in Korean pregnant women based on the mean titer of Korean adults was as follow; thiamine-20%, N'-methylniacinamide-7%, total protein-5%, calcuim13%, iron-19%. 4. No cases were deficient in riboflavin, carotene, phosphorus, total lipid and the mean titer of riboflavin and carotene in Korean pregnant women were high compared with thw mean titer of Korean adults.

This paper describes the structural behavior of T-joints using square hollow sections with longitudinal branch plate that is used to connect brace and high tension tie bar Principal parameters are the ratio of chord widte to thickness(16.7≤2γ(B/T)≤31.3) and branch plate to chord width(0.20≤β(b1/B)≤0.85) The results from 12 specimens tested in compression indicated that failure mode changed from chord flange failure mode to chord web failure mode at β = 0.75 The dominant failure mode was chord flange failure for β ≤ 0.75 According to variety of longitudinal branch plate length, the capacity of strength was less than increasing branch plate length The strength formulae of CIDECT and other researchers are compared with the test results, and finally design guidelines have been presented based on Bae's strength formula for longitudinal branch plate T-joints

Gain of a New Exon by a Lineage-Specific Alu Element-Integration Event in the BCS1L Gene during Primate Evolution

Park, Sang-Je,Kim, Young-Hyun,Lee, Sang-Rae,Choe, Se-Hee,Kim, Myung-Jin,Kim, Sun-Uk,Kim, Ji-Su,Sim, Bo-Woong,Song, Bong-Seok,Jeong, Kang-Jin,Jin, Yeung-Bae,Lee, Youngjeon,Park, Young-Ho,Park, Young Il Korean Society for Molecular and Cellular Biology 2015 Molecules and cells Vol.38 No.11

BCS1L gene encodes mitochondrial protein and is a member of conserved AAA protein family. This gene is involved in the incorporation of Rieske FeS and Qcr10p into complex III of respiratory chain. In our previous study, AluYRa2-derived alternative transcript in rhesus monkey genome was identified. However, this transcript has not been reported in human genome. In present study, we conducted evolutionary analysis of AluYRa2-exonized transcript with various primate genomic DNAs and cDNAs from humans, rhesus monkeys, and crabeating monkeys. Remarkably, our results show that AluYRa2 element has only been integrated into genomes of Macaca species. This Macaca lineage-specific integration of AluYRa2 element led to exonization event in the first intron region of BCS1L gene by producing a conserved 3' splice site. Intriguingly, in rhesus and crabeating monkeys, more diverse transcript variants by alternative splicing (AS) events, including exon skipping and different 5' splice sites from humans, were identified. Alignment of amino acid sequences revealed that AluYRa2-exonized transcript has short N-terminal peptides. Therefore, AS events play a major role in the generation of various transcripts and proteins during primate evolution. In particular, lineage-specific integration of Alu elements and species-specific Alu-derived exonization events could be important sources of gene diversification in primates.

Bae, Woong Jin,Park, Hyo Jung,Koo, Hye Cheong,Kim, Do Ram,Ha, U-Syn,Kim, Kang Sup,Kim, Su Jin,Cho, Hyuk Jin,Hong, Sung Hoo,Lee, Ji Youl,Hwang, Sung Yeoun,Kim, Sae Woong Hindawi Publishing Corporation 2016 Evidence-based Complementary and Alternative Medic Vol.2016 No.-

<P>We evaluated the effects of Seoritae extract (SE) on mild to moderate lower urinary tract symptoms (LUTS) suggestive of benign prostatic hyperplasia (BPH). Seventy-six subjects with mild to moderate LUTS suggestive of BPH were prospectively recruited from the urology outpatient clinic and assigned to either SE (4200 mg or 6 tablets 3 times a day) or matching placebo. The primary outcome variable, the International Prostatic Symptom Score (IPSS), was evaluated at baseline and at 4 and 12 weeks. Postvoid residual volume (PVR), maximum urine flow rate (<I>Q</I><SUB>max</SUB>), and prostate-specific antigen (PSA) levels were evaluated. IPSSs decreased significantly from baseline to 12 weeks within the SE group. Significant improvements in IPSS voiding scores at 4 and 12 weeks were also observed in the SE group compared to the placebo group. IPSS storage and quality of life scores were also significantly decreased at 12 weeks in the SE group. There was no change in <I>Q</I><SUB>max</SUB> or PVR in both groups after 12 weeks. Administration of SE for 12 weeks led to significant improvements in LUTS, and it can be concerned as a reasonable and safe alternative for men with mild to moderate LUTS.</P>

Objective: To compare the clinical and radiological outcome of both sides using the unilateral approach. Methods: Unilateral laminotomy was performed to achieve bilateral decompression. Thirty-nine patients who underwent this procedure were analyzed prospectively using the Oswestry Disability Index (ODI), the visual analog scale (VAS) pain score to evaluate symptoms in both legs, and the radiological morphometric index to calculate the anteriorposterior diameter and midcanal width. The incidence of complications from this approach was then evaluated. Results: The mean follow-up time was 12.2 months. The mean ODI was 48.4 preoperatively and 14.2 postoperatively. The mean dural sac widening of the ipsilateral side (187.0%) was significantly larger (p<0.01) than that of the the contralateral side (145.6%). The VAS improvement ratio ([preoperative VAS score-postoperative VAS score]/[preoperative VAS score]×100) for the pain in each leg was 75.4%(ipsilateral side) and 73.7%(contralateral side). While the VAS improvement ratio for pain in each side was significantly reduced, the difference in the VAS ratio between sides was statistically insignificant (p=0.64). There were 2 cases (5.1%) of dural tearing during the procedure, 1 case (2.6%) of transient paresthesia of nerve roots, and 2 cases (5.1%) of transient paresthesia of the contralateral nerve root. The transient paresthesias of nerve roots never lasted more than 2 weeks. Conclusion: This technique allows for significant decompression of the contralateral canal and excellent clinical outcomes without troublesome complications. Although ipsilateral the dural sac widening was significantly larger than contralateral side, the difference in the clinical outcome between sides was statistically insignificant.

<P>Fabric-based electronic textiles (e-textiles) are the fundamental components of wearable electronic systems, which can provide convenient hand-free access to computer and electronics applications. However, e-textile technologies presently face significant technical challenges. These challenges include difficulties of fabrication due to the delicate nature of the materials, and limited operating time, a consequence of the conventional normally on computing architecture, with volatile power-hungry electronic components, and modest battery storage. Here, we report a novel poly(ethylene glycol dimethacrylate) (pEGDMA)textile memristive nonvolatile logic-in-memory circuit, enabling normally off computing, that can overcome those challenges. To form the metal electrode and resistive switching layer, strands of cotton yarn were coated with aluminum (Al) using a solution dip coating method, and the pEGDMA was conformally applied using an initiated chemical vapor deposition process. The intersection of two Al/pEGDMA coated yarns becomes a unit memristor in the lattice structure. The pEGDMA-Textile Memristor (ETM), a form of crossbar array, was interwoven using a grid of Al/pEGDMA coated yarns and untreated yarns. The former were employed in the active memristor and the latter suppressed cell-to-cell disturbance. We experimentally demonstrated for the first time that the basic Boolean functions, including a half adder as well as NOT, NOR, OR, AND, and NAND logic gates, are successfully implemented with the ETM crossbar array on a fabric substrate. This research may represent a breakthrough development for practical wearable and smart fibertronics.</P>

Double Stent Assist Coiling of Ruptured Large Saccular Aneurysm in Proximal Basilar Artery Fenestration

Woong Bae Park,성재훈,Joon Huh,조철범,양승호,김일섭,홍재택,이상원 대한뇌혈관외과학회 2015 Journal of Cerebrovascular and Endovascular Neuros Vol.17 No.3

Basilar artery fenestration is infrequent and even rarer in association with a large aneurysm. With proximity to brain stem and vital perforators, endovascular coiling can be considered first. If the large ruptured aneurysm with a wide neck originated from fenestra of the proximal basilar artery and the fenestration loop has branches of posterior circulation, therapeutic consideration should be thorough and fractionized. We report endovascular therapeutic details for a case of a ruptured large saccular aneurysm in proximal basilar artery fenestration.

Analysis of the Purpose of Visiting Wetlands Using Pictures Posted on Social Media

Park, Woong-Bae,Park, Siae,Choi, Tae-Jun,Kim, Dae-Hee,Lee, Do-Hee,Do, Yuno National Institute of Ecology 2022 Proceedings of NIE Vol.3 No.2

In this study, 4,136 pictures posted on a social media platform were analyzed to discover wetlands that are worth visiting to experience our cultural values. Pictures from 300 of the 2,499 listed wetlands have been posted in South Korea. Proximity of a wetland was the most important criterion, regardless of the type of wetlands that were visited. People visited wetlands at the time and season when they were good for recreational activities. Most of the subjects in the pictures were the visitors and natural scenery of a wetland. There was no correlation observed between the wetland conditions and the number of pictures taken by the visitors. Sightseeing and leisure activities are a significant part of various ecosystem services offered by wetlands, but most of the visitors seem to be unaware that the place they have visited is a wetland. Therefore, wetland awareness programs are needed, even for wetlands close to the residential areas that many people have already visited in this study.
