This study was carried out in order to explore possibility of artistic activity for strengthening creativity of the gifted children at home by analyzing influence of the gifted children's musical experience and interest level upon creativity. As a result of research, the gifted children's musical experience and interest level were distributed in the mid-lower rank as a whole. The mean in score of creativity was high. Among sub-spheres, originality, abstractness of titles, and resistance to premature closure were surveyed to be especially excellent. And the result of this study was indicated to be high in influence of musical experience and interest level upon creativity. Some conclusions and implications that were obtained through this study are as follows. First, to explore influence of musical experience as artistic activity upon creativity, first of all, the qualitative inspection needs to be given priority to musical activity itself, which is being experienced by the gifted children as the research subjects. Second, there is necessity of paying attention to the musical experience and interest level of the low gifted children. Third, for the gifted children prior to activation of art education, a clear reason why the art education is needed and the usefulness need to be presented.

Background Trunk defects can occur because of surgical site infections after spinal surgery, resection of malignant tumors, or trauma. Herein, we present our experience of using intercostal artery perforator (ICAP) flaps to reconstruct trunk defects without noteworthy complications. Fourteen patients underwent reconstruction with ICAP flaps between March 2015 and March 2019. Methods Patients' data, including age, sex, the cause of the defect, defect size, perforator location, flap size, complications, and follow-up period, were retrospectively reviewed. The mean age of the patients was 56.5 years (range, 19-80 years). All operations were performed after the results of bacterial culture from the wound showed no microbial growth. We found reliable perforators around the defect using Doppler ultrasonography. The perforator flaps were elevated with a pulsatile perforator and rotated in a propeller fashion to the defects. We performed five dorsal and two lateral ICAP flaps. The mean flap dimensions were 12 × 5.5 cm² (range, 6 × 5 to 18 × 8 cm²). Results Primary closure of the donor site was performed. Marginal congestion was observed as a complication in one case, but it healed with no need for revision. The mean follow-up period was 8 months. All patients were satisfied with the surgical outcomes. Conclusion ICAP flaps can be easily mobilized, thereby reducing donor site morbidity without sacrificing the underlying muscles for trunk reconstruction. Therefore, these flaps are useful options for the reconstruction of trunk defects.

Pulmonary aspergilloma is potentially a life threatening disease resulting from the colonization of lung cavities by Aspergillus fumigatus. A case is reported: a 43-year-old man with symtomatic cavitary aspergilloma presenting with severe productive coughing, hemopt sis, occasional fever, and chilling. On preoperative plain chest radiograph and CT scan, we could find a rounded irregular opacity in a large pulmonary cavity. He received 2 separate operations for therapeutic need. At the first opertion, we performed cavernostomy and thoracoplasty because of severe pleural adhesions, tearing of cavity wall, and high risk of respiratory insufficiency. At the second operation, we performed myoplasty and omentoplasty for closure of remaining air space and complete wrapping of the BPF site. All symptoms of dyspnea and hemoptysis have since resolved. We believed that in the high risk patients who have severe respiratory symptoms, such as in aspergilloma and open cavity with a risk of respiratory insufficiency, cavernostomy followed by myoplasty or omentoplasty should be recommended.

The chemical compositions of $PM_{2.5}$ and $PM_{10}$ and associated high-molecular-weight polycyclic aromatic hydrocarbons (PAHs) were investigated during winter and summer at a roadside and an urban background site in Saitama, Japan. The average concentrations of $PM_{2.5}$ exceeded the United States Environmental Protection Agency standards during both periods. Carbonaceous components were abundant in both the observed and calculated (by means of a mass closure model) chemical composition of $PM_{2.5}$. Traffic-related pollutants (elemental carbon and high-molecular-weight PAHs) were strongly associated with $PM_{2.5}$ rather than with larger particles. The mass concentrations of $PM_{2.5}$, as well as those of EC and PAHs associated with the particles, at the two sites were strongly correlated. Comparison of our data with source profile ratios indicates that diesel-powered vehicles were probably the main source of the measured PAHs. The PAHs concentrations were affected by meteorological conditions during our study. Our results highlight the need for the establishment of standards for $PM_{2.5}$ in Japan.

The response of honeybee (Apis mellifera L.) pollination on canola yield with reference to most suitable number of bee hive need per unit area of crops in order to meet optimum pollination needs and better economic yields by comparing number of hives and yield components an experiment was conducted at Beekeeping and Hill Fruit Pests Research, Station Rawalpindi during 2017-18 in complete randomized block design with two sets of four treatments for comparison: 1 hive acre^-1, 2 hives acre^-1, 3 hives acre^-1 and 0 hive acre^-1. The hives were kept inside the experimental area. Parameters were assessed: pollination density, pollinator's diversity, agronomic and economic yield. In case of pollination density, the cumulative mean abundance bee species revealed that at 1200 hours, Apis mellifera was the most abundant and frequent visitor with a mean population of 8.69 bees/plant followed by A. dorsata (0.72), Syrphid fly (0.2) and other pollinators. Minimum bee population was observed during 1400 hours, mainly due to the closure of flowers and partially due to high temperature (>35℃). Pollinator diversity revealed that A. mellifera was the most dominant pollinator of Brassica crop with highest abundance (71%). A. dosata ranked 2^nd (16%) followed by A. florea (6%) respectively.

Background noise and room reverberation are two causes of degradation in speech in listening situations. Many algorithms developed to enhance reverberant speech. In this paper we propose a dereverberation method for enhancement of speech using modified the linear prediction(LP) residual in reverberant room condition. The proposed dereberberation method based on the fact that the signification excitation of the vocal tract system takes place at the instant of glottal closure in voiced speech. Our method used delay information form each sensor, and we need reverberant signals from 3 sensors. We obtain a new LP residual signal using modified IP residual combination which derived form weighting of the LP residual and the Hilbert transform of LP residual. The nature of the coherently added Hilbert envelop has several large amplitude spikes because of the effects of noise and reverberation. This residual of the clean speech is used to excite the time-varying all-pole filter to obtain the enhanced speech. We achieved simulation of proposed algorithm for performance analysis in reverberation environment. The proposed algorithm improves substantially the quality of reverberant speech.

Background The result of illicit polymer injection is chronic inflammation with foreign-body granuloma (FBG) formation. Treatment can be divided into medical and surgical. Some patients develop severe complications with need surgical treatment. This study aims to describe patients who underwent surgical removal of the FBGs and autoimmune/inflammatory syndrome induced by adjuvants (ASIA); additionally, we evaluated the quality of life after surgery. Methods In this retrospective single-center study, the authors examined data of patients who underwent surgical removal of FBG caused by illicit polymer injection for cosmetic purposes and confirmed ASIA from 2015 to 2020 by three different surgical approaches. Descriptive summary statistics were reported on patient demographics, presenting symptoms and clinical examination features, treatment strategies, histopathology reports and quality of life. Results The cohort included 11 female patients with FBGs and ASIA. The most affected anatomical zones were the combination of gluteal region, thighs and legs (40%); and thighs with legs (20%). Main presentation was: skin hyperpigmentation (90.9%), skin induration (63.6%), chronic fatigue (63.6%), and ulcers (36.4%). Surgical modalities consisted of: ultrasonic-assisted liposuction in four patients (36.4%); open en bloc excision and primary closure in four patients (36.4%); and open en bloc excision and microsurgical reconstruction in three patients (27.2%). The postoperative quality of life visual analog scale score was 83.9. Conclusions ASIA treatment represents a challenge for the plastic surgeon. Adequate surgical treatment emphasizing, when possible, the total or near-total resection of the FBG must be performed to improve ASIA evolution.

In the commercially managed timber lands, the information such as height, age, stand density, canopy closure and leaf area index need to be collected periodically. Stand volume is the most fundamental information in the valuation of timber, however, stand age information is the primary element of forest inventory and these two are highly correlated. Conventional method of collecting stand age information by field surveys such as ring count method is accurate; however, it is expensive, labor-intensive and time consuming. In the present study it was aimed to collect stand age information using modem techniques in a commercially managed timberland situated in Tennessee, USA. The Landsat Thematic Mapper (TM), Enhanced Thematic Mapper (ETM+) of three different periods, Shuttle Radar Topography Mission (SRTM), National elevation dataset (NED) and field inventory data were used. Normalized difference vegetation index (NDVI) and Tasselled Cap (TC) transformation techniques were applied on the TM and ETM+ data. The regression analysis was carried out to identify the correlation between stand age and NDVI, TC. In the present study about 2,469 datasets were analyzed. The $R^{2}$ value for stand age estimation was 0.713. The NDVI, TC2 and TC3 were found to produce accurate timber age information.

The traditionally useful coverage methods of the wrist and hand soft tissue defect are the chinese forearm flap, the ulnar forearm flap. But, this flaps are inevitably sacrifice major vessel to the hand. Advantages of the posterior interosseous artery island flap(PIA Flap) is no need to sacrifice blood supply to the hand and supply relatively large thin, good quality flap and more cosmetic than other forearm flaps. But, it is difficult to dissect and raise because of deep seat, close relation with the posterior interosseous nerve and anatomic variation. Authors evaluated 8 cases of 7 patients in the department of orthopaedic surgery, college of medicine, Hallym University from January, 1993 to December, 1995. The results are as follows: 1. The satisfactory coverage was achieved 7 cases and 1 case failed because of anatomic variation. 2 The pedicle length is average 9cm and the flap size is variable from 3cm by 4cm to 5cm by 8cm. 3. The donor site defect was repaired by direct closure in 5 cases, remained 3 cases combined with skin graft. From our experience we conclude that the PIA flap is one of the useful coverage methods of the wrist and hand soft tissue defect.

To prevent the spread of disease in aquaculture, it is a need for a system to predict fish diseases while monitoring the water quality environment and the status of growing fish in real time. The existing research in predicting fish disease were image processing techniques. Recently, there have been more studies on disease prediction methods through deep learning techniques. This paper introduces the research results on how to predict diseases of Paralichthys Olivaceus with deep learning technology in aquaculture. The method enhances the performance of disease detection rates by including data augmentation and pre-processing in camera images collected from aquaculture. In this method, it is expected that early detection of disease fish will prevent fishery disasters such as mass closure of fish in aquaculture and reduce the damage of the spread of diseases to local aquaculture to prevent the decline in sales.
