Research on CMS decomposition of South Korea’s manufacturing exports to China
Authors: Kim J S 
Published: June 2021

Abstract
This paper analyzes the export performance of South Korea’s manufacturing products to China from 2000 to 2020 by using Constant Market Share (CMS) model. The manufacturing products are mainly electrical machinery, equipment, vehicles, optical photographic, iron and steel, organic chemicals, and related products. According to the analysis, South Korea’s manufacturing products to China had continued to increase in demand of the China market from 2000 to 2014, but it has stagnated or declined since 2015, owing to the development of manufacture-related technology of China and its lower dependence on South Korea’s products. Through CMS decomposition, it is found that: the structure effects in stages of 2000-2015, 2006-2010 and 2011-2015 contributed the most to the change of exports in China market. However, during the period of 2016-2020, it was a high negative level due to the increased self-sustaining power of China. Moreover, the structure effects are mainly from the growth effects, except for the period of 2016-2020, which was from the commodity effect. In all the four stages, the competitive effect has a positive value. Especially, in the period of 2016-2020, it reached a highest level of 620.20%, because of its high technology and high quality. Through second order decomposition, it is found that the competitive effects are mainly from the overall competitive effects, except for the period of 2006-2010, which is mainly from commodity competitive effect. In the case of residual effect, compared with the structure effect and the competitive effect, its contribution to the change of exports is very low. And the residual effects are mainly from the pure residual effects rather than dynamic effects.

Abstract
The heavy metal Cd seriously affects the growth and development of humans, animals and plants, at the same time, it has the characteristics of wide sources and easy delivery. In this paper, the effects of Cd contaminated soil remediation by biodegradable organic phosphonic acids HEDP, BHMTPMPA, HDTMPA and ATMP on the germination characteristics of plants were studied. The results showed that when the concentration of organic phosphonic acid HDTMPA was 4%, the germination characteristics of Zinnia elegans Jacq. are the best among the four organic phosphonic acids, the germination rate, germination potential, germination index, vigor index, root length, bud length and seedling dry weight were 62%, 25.1, 11.8, 41.3, 1.8 cm, 3.5 cm and 158 mg respectively.

Published: June 2021

Abstract
This paper applied the principle of critical slowing down to the processing of radon concentartions observation data, calculated the autocorrelation coefficient and variance which can characterize critical slowing down by taking Wenchuan Ms8.0 earthquake on May 12, 2008, Lushan Ms7.0 earthquake on April 20, 2013, Minxian-Zhangxian Ms6.6 earthquake on July 22, 2013, Jiuzhaigou Ms7.0 earthquake on August 8, 2017 as examples. The result indicated that the water radon concentration at several stations has obvious critical slowing phenomenon before server earthquakes. The formation mechanism of radon concentration anomalies in seismic underground fluids was discussed in the context of the focal mechanism solution of several earthquakes. It is considered that the phenomenon of critical slowing down before server earthquakes is related to the earthquakes occurrenced combined with the hydrodynamic mechanism of radon anomaly and the structure of the abnormal points.
Exploring Proximal LGBTQ+ Minority Stressors Within Physical Activity Contexts from a Self-determination Theory Perspective
Authors: Herrick Shannon S C , Rocchi Meredith A , Sweet Shane N , Duncan Lindsay R 
Published: June 2021

Abstract

Background
LGBTQ+ (lesbian, gay, bisexual, transgender, queer, etc.) individuals experience challenges such as discrimination and marginalization (referred to as minority stressors) that are detrimental to their mental and physical health. Specifically, proximal or internalized LGBTQ+ minority stressors may influence motivation for and willingness to participate in physical activity.

Purpose
To explore whether proximal LGBTQ+ minority stressors relate to the basic psychological needs—motivation—physical activity pathway, as per self-determination theory.

Methods
An online cross-sectional survey was completed by 778 self-identified LGBTQ+ adults. Structural equation modelling analyses were used to examine how proximal LGBTQ+ minority stressors relate to the motivational sequence.

Results
Findings support that proximal LGBTQ+ minority stressors are negatively associated with psychological need satisfaction within physical activity (β = −.36), which in turn is positively associated with autonomous motivation (β = .53) and reported physical activity participation (β = .32). Overall, the final model accounted for 13% of variance in need satisfaction (small effect size), 53% of variance in autonomous motivation (moderate-large effect size), and 10% of variance in moderate-to-vigorous physical activity levels (small effect size).

Conclusions
Future research focused on increasing LGBTQ+ participation in physical activity should investigate the effects of (a) reducing proximal LGBTQ+ minority stressors and (b) better supporting LGBTQ+ adults’ autonomy, competence, and relatedness within physical activity contexts.

Published: June 2021

Abstract

Objectives
As we move toward human papillomavirus (HPV) only as the preferred cervical cancer screening method, we performed a retrospective analysis of Black and White women with negative cytology (Papanicolaou negative [PAPneg]) and positive high-risk HPV (hrHPV) (HPVpos) results and determined follow-up.

Methods
We searched our pathology data system for patients with PAPneg/HPVpos results (2017-2019). Follow-up data were reviewed (39 months), and a comparison among race was performed.

Results
In total, 1,728 patients were identified (Black, 53%; White, 47%). Twenty-nine percent of the patients had no follow-up with no difference among the races. HPV 16 was more common among Whites (P &lt; .01), while non-16/18 hrHPV was more common among Black patients (P = .01). A total of 30 (3.3%) Black and 26 (3.2%) White patients were diagnosed with cervical intraepithelial neoplasia grade 2/3 (CIN 2/3). More White women were diagnosed on biopsy alone (negative endocervical curettage) compared with Black women (20 vs 9, P &lt; .01). Meanwhile, there were 21 Black and 6 White women with CIN 2/3 on endocervical curettage (P = .01).

Conclusions
Follow-up of women with PAPneg/HPVpos remains a challenge. There was no disparity in follow-up when cohorts were compared. However, Black women had higher numbers of high-grade intraepithelial lesions on endocervical curettage.

Summary
Peroral endoscopic myotomy (POEM) in patients with achalasia who are status post bariatric surgery may be technically challenging due to postsurgical scarring and altered anatomy. The aim of the study was to assess the efficacy and safety of POEM for achalasia in patients with prior bariatric surgery. A review of prospectively maintained databases at three tertiary referral centers from January 2015 to January 2021 was performed. The primary outcome of interest was clinical success, defined as a post-treatment Eckardt score ≤ 3 or improvement in Eckardt score by ≥ 1 when the baseline score was &lt;3, and improvement of symptoms. Secondary outcomes were adverse event rates and symptom recurrence. Sixteen patients status post Roux-en-Y gastric bypass (n = 14) and sleeve gastrectomy (n = 2) met inclusion criteria. Indications for POEM were achalasia type I (n = 2), type II (n = 9), and type III (n = 5). POEM was performed either by anterior or posterior approach. The pre-POEM mean integrated relaxation pressure was 26.2 ± 7.6 mm Hg. The mean total myotomy length was 10.2 ± 2.7 cm. The mean length of hospitalization was 1.4 ± 0.7 days. Pre- and postprocedure Eckardt scores were 6.1 ± 2.1 and 1.7 ± 1.8, respectively. The overall clinical success rate was 93.8% (15/16) with mean follow-up duration of 15.5 months. One patient had esophageal leak on postprocedure esophagram and managed endoscopically. Dysphagia recurred in two patients, which was successfully managed with pneumatic dilation with or without botulinum toxin injection. POEM appears to be safe and effective in the management of patients with achalasia who have undergone prior bariatric surgery.
The Utility of a Bumble Bee (Bombus spp.[Hymenoptera: Apidae]) Brood Test for Evaluating the Effects of Pesticides
Authors: Krueger Annie J , Early Tara M , Ripperger Randy J , Cabrera Ana R , Schmehl Daniel R 
Published: June 2021

AbstractRisk assessment for chemicals in the United States relies upon the honey bee (Apis meliffera L. [Hymenoptera: Apidae]) as a surrogate for other bee species. There is uncertainty in extrapolating honey bee toxicity data to bumble bees due to differences in life history strategies, food consumption, and nest structure. Here we evaluated the design of a queenless bumble bee microcolony test that could be considered for generating larval toxicity data. Three microcolony studies were conducted with Bombus impatiens to evaluate the effects of exposure to 1) diflubenzuron in pollen, 2) dimethoate in pollen, and 3) dimethoate in sucrose. Immature drone bee emergence, worker survival, pollen, and sucrose utilization were measured throughout the study duration. For dimethoate, a 10-d chronic adult bumble bee study was also conducted to compare microcolony endpoints to toxicity endpoints on individual adults. Microcolonies exposed to 10 mg diflubenzuron/kg pollen produced fewer adult drones despite no effects on worker survival. Microcolonies treated with dimethoate at ≥3 mg a.i./kg pollen and ≥0.1 mg a.i./kg sucrose solution produced fewer drones. Exposure to dimethoate in the 10-d chronic adult study resulted in direct mortality to the adult workers at ≥0.1 mg a.i./kg diet. Results from the 10-d study suggest direct effects of dimethoate on workers in the microcolony will alter provisioning of diet to the brood, resulting in lower drone production in the microcolony. Our data suggest that the microcolony study is only appropriate to assess brood effects to bumble bees for substances with low toxicity to adults, as demonstrated with diflubenzuron.

Abstract

OBJECTIVES
Recent trials have begun to explore immune checkpoint inhibitors for non-small cell lung cancer in the neoadjuvant setting, but data on tumour response and surgical outcome remain limited.

METHODS
Retrospective evaluation of clinical data from patients with non-small cell lung cancer treated with immune checkpoint inhibitors followed by lung resection was performed at 2 large volume institutions (1 North American, 1 European). Data were analysed using Chi-squared, Fisher’s and Wilcoxon rank-sum tests where appropriate.

RESULTS
Thirty-seven patients were identified from 2017 to 2019. Forty-nine per cent were Stage IIIB and IV. Forty-six per cent received immunotherapy alone and 54% in combination with chemo- and/or radiotherapy. Sixteen per cent of cases were successfully performed minimally invasively. Twenty patients were operated with lobectomy (6 of these with wedges or segments of a neighbouring lobe, 2 with sleeve resections and 1 with a chest wall resection), 4 with bilobectomies, 11 with pneumonectomy (including 5 extrapleural pneumonectomies and 1 atrial resection) and 1 with a wedge resection. Overall, 10 patients (27%) developed postoperative complications and the 90-day mortality was zero. One-year recurrence-free survival was 73% for stage II/IIIA and 55% for stage IIIB/stage IV. The major pathologic response rate was 34%.

CONCLUSION
In this retrospective study, lung resection after immunotherapy (alone or in combination) is safe, although often requires complex surgery. Due to increasing number of clinical trials adopting immunotherapy in the neoadjuvant setting, it is likely that this therapy will become part of standard of care. Immunotherapy may also allow surgery to have a role for selected patients with advanced disease.
Lipschitz Algebras and Lipschitz-Free Spaces Over Unbounded Metric Spaces
Authors: Albiac Fernando , Ansorena José L , Cúth Marek , Doucha Michal 
Published: June 2021

Abstract
We investigate a way to turn an arbitrary (usually, unbounded) metric space ${{\mathcal{M}}}$ into a bounded metric space ${{\mathcal{B}}}$ in such a way that the corresponding Lipschitz-free spaces ${{\mathcal{F}}}({{\mathcal{M}}})$ and ${{\mathcal{F}}}({{\mathcal{B}}})$ are isomorphic. The construction we provide is functorial in a weak sense and has the advantage of being explicit. Apart from its intrinsic theoretical interest, it has many applications in that it allows to transfer many arguments valid for Lipschitz-free spaces over bounded spaces to Lipschitz-free spaces over unbounded spaces. Furthermore, we show that with a slightly modified pointwise multiplication, the space ${\textrm{Lip}}_0({{\mathcal{M}}})$ of scalar-valued Lipschitz functions vanishing at zero over any (unbounded) pointed metric space is a Banach algebra with its canonical Lipschitz norm.
Application of powerline noise cancellation method in correlation identification of controlled source electromagnetic method

Published: June 2021

Abstract
Powerline interference in the controlled source electromagnetic method has traditionally been one of the biggest conundrums plaguing geophysicists, and its conventional denoising methods primarily include filtering and noise estimation. The filter method leaches noise at specific frequency points, which might also filter useful signals; the noise estimation method significantly eliminates interference, whereas the premise is that the noise is stable after a short time and a recorder is necessary in the field. In the present study, using the periodicity and symmetry of powerline noise, we propose a subtraction and an addition method for cancellation of the powerline noise. First, the transmitted signal is optimized so that the equivalent transmitted signal is an m sequence; then the response signal is processed by using the cancellation method; subsequently, the correlation identification is applied and finally, we solve the earth impulse response by means of the Wiener filter deconvolution method. Simulation experiments and field data tests demonstrate that the powerline noise can be well suppressed by the cancellation method proposed in the present study, so that the system identification accuracy is greatly improved. The method is simple in principle and effective in removing powerline noise, which presents a novel perspective on noise elimination for system identification.
Acute traumatic abdominal wall hernia—value of the physical examination: case report
Authors: Hernandez Cervantes Barbara Yordanis , Martínez Lopez Duniesky , Guzman Lambert Radisnay , Rodríguez Gonzalez Mariuska , Meah Mary 
Published: June 2021

AbstractAcute traumatic abdominal wall hernia (TAWH) is a rare type of hernia that occurs after a low or high velocity impact of the abdominal wall against a blunt object with few cases reported. Perforations of the hollow viscera commonly follow abdominal trauma and likely require surgery for hemorrhage and sepsis source control. We report a case where a high velocity impact of the abdominal wall against the stump of a felled tree caused a TAWH with concomitant gastric perforation in a 20-year-old male patient who required exploratory laparotomy with primary repair of the stomach and fascia. The physical examination findings without previous history of abdominal hernia and pneumoperitoneum in the chest X-ray made suspect our diagnosis and it was confirmed intraoperatively. At 3 months postoperatively the patient has a strong abdominal wall. It is imperative to emphasize the importance of the physical examination goal of not losing diagnosis of TAWH.
‘The Eyes of an Intellectual Vampire’: Michael Field, Vernon Lee and Female Masculinities in Late Victorian Aestheticism
Authors: Dytor Frankie 
Published: June 2021

Abstract
This article reframes debate on the intersections of female aestheticism and cultural dissidence by focusing on the construction of queer masculinities at the end of the nineteenth century. Looking at the diary of Michael Field (Katharine Bradley and Edith Cooper), it examines the descriptions of Vernon Lee, Clementina (‘Kit’) Anstruther-Thompson and Maud Cruttwell during the Fields’ trip to Italy in 1895. The ambivalent presentation of these figures in the diary reveals a conflicted legacy of aestheticism, centred around the inheritance, interpretation and embodiment of queer masculinity. The article argues that the Fields developed themes associated with a previous generation of male aesthetes in order to articulate gender difference between themselves and other female-bodied aesthetes. In particular, it considers how the gender-variant Fields rejected Lee, Anstruther-Thomson and Cruttwell’s trans-masculinities as perversions of their sex.
Persistent reading difficulty despite improved focus on a stimulant medication
Authors: Anderberg Emily 
Published: June 2021

Abstract
Specific learning disorder is a developmental disorder characterized by difficulties learning a specific academic skill (reading, written expression, or mathematics), leading to substantially reduced achievement compared to same-age peers. Attention-deficit/hyperactivity disorder is a common comorbidity. Low academic performance must not be attributable to a more general condition such as intellectual disability, lack of educational opportunity, or low language proficiency. The learning difficulties are present from the early school years. The diagnostic assessment includes standardized academic achievement testing, review of academic records, and cognitive testing to rule out intellectual disability. Treatment includes specialized multimodal educational interventions in conjunction with academic accommodations. Pharmacologic treatment of comorbid psychiatric disorders may provide indirect benefit by helping the child better access educational interventions.
A child with inattention, hyperactivity, and impulsivity
Authors: Ozdemir Sirin , Donnelly Craig L. 
Published: June 2021

Abstract
Attention-deficit/hyperactivity disorder (ADHD) is a neurodevelopmental disorder that manifests in childhood with symptoms of inattention, hyperactivity, and impulsivity. The symptoms must occur in more than one setting and cause an impairment in functioning. Attention-deficit/hyperactivity disorder is one of the most common neurobehavioral disorders of childhood and may persist into adulthood. The assessment for ADHD should include a clinical history, review of information about school functioning, and assessment of common comorbid psychiatric disorders. Children with ADHD may be unaware of their symptoms, highlighting the need for collateral information from parents and teachers. Treatment may involve behavioral/psychologic interventions, educational interventions, and medications. Behavioral interventions are the first-line approach for preschool-age children, while medication treatment should be considered the first-line approach for school-aged children and adolescents. Pharmacologic treatments include stimulant and nonstimulant medications.
Repetitive throat clearing, blinking, and grimacing
Authors: Sipsock Danielle 
Published: June 2021

Abstract
Tourette’s disorder requires the presence of multiple motor tics and at least one vocal tic that have been present for at least one year. A tic is a sudden, rapid, recurrent, nonrhythmic motor movement or vocalization. Tics are often associated with a premonitory urge and may be temporarily suppressed. They typically begin between the age of four and six years, peak in severity in early adolescence, and then diminish. The majority of individuals spontaneously achieve remission by early adulthood. Because tic disorders commonly co-occur with psychiatric disorders, they should be screened for in every psychiatric interview. Treatment should begin with psychoeducation and focus on symptom reduction rather than remission. Behavioral interventions, including habit reversal therapy, may be considered. Medications, such as antipsychotics and alpha2 adrenergic agonists, should be considered if tics cause severe impairment and are moderate to severe.
Teenager with paranoia and hallucinations preceded by a decline in academic and social functioning
Authors: Pereira Joseph A. 
Published: June 2021

Abstract
Schizophrenia is a primary psychotic disorder characterized by two or more of hallucinations, delusions, disorganized speech, disorganized or catatonic behavior, and/or negative symptoms. At least one of the symptoms must be hallucinations, delusions, or disorganized speech. There must be continuous signs of the disturbance for at least six months, although the duration may be shortened with appropriate treatment. The symptoms of schizophrenia typically begin between the ages of 15 and 30 years. Active symptoms are typically preceded by a prodromal phase, marked by a decline in academic and social functioning. The assessment of an adolescent with suspected schizophrenia should include a psychiatric assessment and complete medical history to rule out medical conditions that mimic psychosis. The primary treatment is antipsychotic medications. Adjunctive psychological and social interventions can improve treatment adherence and clinical outcomes.
