Nail bed and flap reconstructions for acute fingertip injuries – A case review and report of a chemical burn injury
Authors: Gunasagaran Jayaletchumi , Sian Khoo Saw , Ahmad Tunku Sara
Published: April 2019

Nail bed injuries were commonly found concomitantly with fingertip injuries. Reconstruction of fingertip including the nail bed should be attempted at acute stage. Aim of the surgery was to restore as much finger length and achieve normal nail growth. In chemical burns, the initial presentation might not reflect the exact extent of injury. Appropriate acute management must be initiated while waiting for demarcation. We report a case of young stewardess who presented with fingertip chemical burn injury. Surgical debridement was done on third day post-injury. A cross-finger flap to cover skin defect and split-thickness nail bed grafting from the remnant of injured finger were done. Excellent functional and cosmetic outcome was achieved in 6 months. Surgical treatment in a chemical burn was similar to traumatic injury. Nail bed graft was the best option for nail bed reconstruction. In cases of soft tissue loss, advancement or pedicle flaps are beneficial.

Enhancing Accessibility of Physical Activity During Pregnancy: A Pilot Study on Women’s Experiences With Integrating Yoga Into Group Prenatal Care
Authors: Kinser Patricia , Jallo Nancy , Thacker Leroy , Aubry Christine , Masho Saba
Published: April 2019

Introduction:

Health guidelines suggest that pregnant women should participate in daily physical activity, yet rarely do they meet these guidelines. Means to enhance accessibility of physical activity for pregnant women are required, and yoga has been suggested as a possible method to enhance women’s sense of confidence and competence with physical activity. In this pilot study, our primary aim is to evaluate pregnant women’s perceptions about their lived experience of an intervention which integrates a low-intensity form of physical activity, yoga, into prenatal care; our secondary aim is to evaluate changes in participants’ self-efficacy for physical activity and time spent in physical activity over time.

Methods:

Held in an outpatient obstetrics department of an urban hospital system in the United States, this pilot study enrolled 16 pregnant women to participate in the intervention throughout their pregnancy. We explored participants’ lived experience of the intervention using qualitative methods (phenomenology). Means, variances, and covariances were calculated for the 2 measures (self-efficacy and time spent in physical activity) over the intervention period.

Results:

Qualitative findings from focus groups suggest that it is acceptable for prenatal yoga to be integrated into group prenatal care classes and women reported increased confidence with physical activity during pregnancy. Participants did not consider the intervention to fit within the traditional definition of exercise. Women reported increased amounts of time spent in physical activity from baseline to the end of pregnancy, but there were no statistically significant changes in self-efficacy over time.

Discussion:

The integration of gentle physical activity into the group prenatal care model warrants further attention for potential benefits with regard to maternal physical and mental wellness.
Health Extension Workers Involvement in the Utilization of Focused Antenatal Care Service in Rural Sidama Zone, Southern Ethiopia: A Cross-Sectional Study
Authors: Gebretsadik Achamyelesh , Teshome Million , Mekonnen Mekdes , Alemayehu Akalewold , Haji Yusuf
Published: April 2019

Background:

Health extension workers (HEWs) are primarily been assigned in rural areas of Ethiopia to provide maternal and child health services. Few studies have been done to investigate HEWs’ contributions towards maternal health services. This study describes HEWs involvement in the utilization of focused antenatal care (FANC).

Methods:

A population-based cross-sectional survey was conducted between January 21 and February 4, 2017. Mothers (2300) who gave birth in the last 6 months (0-6 months) in randomly selected 30 kebeles in the rural Sidama zone, participated in the study. A face-to-face interview was done using a structured questionnaire adapted from the Saving Newborn Lives Program. The main outcome variable was FANC utilization. Descriptive statistics and multivariate logistic regression analysis were used using SPSS statistical software.

Results:

The FANC was used by 525 (24.36%; 95% confidence interval [CI]: 22.5%-26.2%) women. Health extension workers accounted for 244 (46.47%; 95% CI: 43.5-47.7%) of mothers. The FANC utilization was less likely among those who were illiterate (adjusted odds ratio [AOR]: .32; 95% CI: .18-.57) and those who attended first cycle (AOR: .41; 95% CI: .23-.74), those who attended secondary cycle (AOR: .47; 95% CI: .27-.82), primipara (AOR: 0.53; 95% CI: .35-.83), and those who gave birth at home (AOR: .66; 95% CI: .51-.84). Mothers who had knowledge of pregnancy danger signs (AOR: 1.42; 95% CI: 1.2-1.7) and exposure to mass media (AOR: 1.35; 95% CI: 1.1-1.66) were more likely to utilize FANC.

Conclusions:

FANC utilization in this study was low compared to other studies. The HEWs had a major contribution to the services. However, it is low when compared to the plan set by the state ministry of health. The existing health extension program could be strengthened by increasing the number of HEWs. Empowering rural mothers through continuous education program to enhance the utilization of maternal health services.
Recurrent Cough and Expectoration for 10 Years: A Case Report
Authors: Huang Ting , Li Caihong , Liu Daishun
Published: April 2019

Rationale. Most cases of cystic fibrosis occur in Europe, with only a few occurring in Asia. Pulmonary cystic fibrosis is not a rare disease, but in children it is a potentially life-threatening condition. Children suffering from pulmonary cystic fibrosis rarely survive to adulthood, and responses to treatment are generally poor. The most common cause of cystic fibrosis is a genetic mutation on chromosome 7. Patient concerns. A 15-year-old boy with healthy parents suffered from a recurrent cough and expectoration for nearly 10 years. Six years previously, a definitive diagnosis of pulmonary cystic fibrosis and hepatic cirrhosis was made at the Beijing Children’s Hospital. The first occurrence of hematemesis occurred 1 year ago. The main symptoms, which caused this period of hospitalization, were cough, expectoration, and hematemesis. Diagnoses. The underlying cause was finally determined to be the cystic fibrosis transmembrane conductance regulator gene (p.G970D). After genetic and sweat testing performed at the Beijing Children’s Hospital in 2012, a definitive diagnosis of cystic fibrosis was made. Interventions. The patient was administered hemostatic treatment, antibiotics, and cough relief and sputum reduction therapy. Outcomes. The patient’s condition rapidly improved and continued to remain stable, though future relapse is possible following respiratory tract infections. Lessons. This case indicates that in the case of any child that presents a recurrent cryptogenic cough and expectoration, whether accompanied by hematemesis or not, pulmonary cystic fibrosis should be considered. In order to determine underlying causes and prepare for cystic fibrosis transmembrane conductance regulator modulator therapy, genetic and sweat testing are recommended to be conducted if available.

Published: April 2019

Aim. To determine the social, physical, and emotional impact of living with Perthes’ disease on affected children and their family (caregivers). Patients and Methods. Through a mixed methods approach, we interviewed 18 parents and explored the perspectives of 12 children affected by Perthes’ disease (mean = 7.1 years, SD = ±4.1 years) using a survey tool. Thematic analysis of parents’ interviews provided an insight into disease-specific factors influencing patients and family’s daily life activities. Using the childhood survey tool, good and bad day scores were analyzed using MANOVA (multivariate analysis of variance). Results. Thematic analysis of the parent interviews (main themes n = 4) identified a marked effect of the disease on many facets of the child’s life, particularly pain and the impact on sleep, play, and school attendance. In addition, the interviews identified a negative effect on the family life of the parents and siblings. Children indicated that activities of daily living were affected even during “good days” ( P < .05), but pain was the key limiting factor. Conclusion. Perthes’ disease negatively affects the social, physical, and emotional well-being of children and their family. These findings provide outcome domains that are important to measure in day-to-day care and add in-depth insight into the challenges caused by this disease for health care professionals involved in clinical management.

Authors: Magomedova Nina , Bastida-Vialcanet Ramon
Published: April 2019

This case is based on La Casa de Carlota (Carlota’s House), a limited liability company founded in 2013 and located in Barcelona. The company integrates a design studio and a professional communication agency and employs people with Down’s syndrome or autism. This case features the decision process followed by the two cofounders, José Maria Batalla and Sergi Capell, regarding the opportunity of growing, by either scaling up the activity of the company or replicating the model in other countries. The case describes the concerns that the entrepreneurs had to face in order to make a decision, such as the choice of funding sources in order to finance the growth, or the issues related to the hiring and managing of people with Down’s syndrome or autism. The case also describes the background of the entrepreneurs, the start-up, and the industry. The case introduces the students to the social entrepreneurship field and explains a business model that generates an important social impact. It also introduces a topic of start-ups’ scaling and growth, and different alternatives for financing them. The case sheds light on critical questions that social entrepreneurship students, scholars, investors, and authorities often pose.
One-step templated synthesis of chiral organometallic salicyloxazoline complexes
Authors: Luo Mei , Zhang Jing Cheng , Yin Hao , Wang Cheng Ming , Morris-Natschke Susan , Lee Kuo-Hsiung
Published: April 2019

Background

The general approach to the synthesis of metal complexes begins with ligand synthesis, followed by ligand reaction with metal salts to afford organometallic complexes. Our research group first reported a one-pot multicomponent synthesis of chiral oxazolinyl–zinc complexes, in the presence of a large amount of ZnCl2 (0.4–2.6 equiv.), with the yields of some products reaching 90%.

Results

Our prior strategy was extended to use copper, cobalt, nickel, manganese, palladium or platinum salts as the third component. The one-step method used 1.0 equivalent of a metal salt, such as M(OAc)2·nH2O or MCl2·nH2O (M: Cu, Co, Ni, Pd or Pt, n = 1, 2 or 4), as a reagent to generate chiral salicyloxazoline complexes 1–8 in the reaction of 2-cyanophenol with different d- and l-amino alcohols.

Conclusion

Complexes 1–8 were obtained using a one-pot method with a sequential strategy. The reaction outcome was demonstrated for three-component reactions between metal salts, amino alcohols and 2-hydroxybenzonitrile to afford organometallic complexes in good yields (65–95%).

INTRODUCTION:

The optimal structure for survivorship care plan (SCP) programs and methodology for generating treatment summaries (TSs) has not yet been defined, but the Commission on Cancer and the National Accreditation Program for Breast Centers both mandate that participating oncology programs implement SCP-TS processes for patients that have completed treatment.

METHODS:

We used the Institute for Healthcare Improvement’s Plan-Do-Study-Act model for conducting a quality improvement project evaluating two different SCP-TS programs implemented at the Henry Ford Health System/Henry Ford Cancer Institute’s Breast Oncology Program in Detroit, Michigan. System I involved TSs drafted by nonspecialist breast clinic staff; System II involved TSs vetted through a multidisciplinary breast specialist conference approach. Accuracy of basic documentation entries related to dates and components of treatment were compared for the two approaches.

RESULTS:

Seventy-one System I and 93 System II documents were reviewed. Documentation was accurate in at least 90% of documents for both systems regarding delivery of chemotherapy and/or endocrine therapy and for documenting the identity of the various members of the cancer treatment team. Both systems had notable inaccuracies in documenting type of surgery performed, but System II had fewer inaccuracies than System I (33.78% v 51.67%, respectively; P = .05). System II, compared with System I, had fewer inaccuracies in documenting date of diagnosis (9.68% v 25.35%, respectively; P = .01) and had less missing information for dose of radiation delivered (9.33% v 33.9%, respectively; P < .01).

CONCLUSION:

A multidisciplinary team approach to drafting and reviewing SCP-TS documents improved content accuracy for our program, but ongoing education regarding documentation of various surgical procedures is warranted.
Distinct gene-selective roles for a network of core promoter factors inDrosophilaneural stem cell identity
Authors: Neves Alexandre , Eisenman Robert N.
Published: April 2019

The transcriptional mechanisms that allow neural stem cells (NSC) to balance self-renewal with differentiation are not well understood. Employing an in vivo RNAi screen we identify here NSC-TAFs, a subset of nine TATA-binding protein associated factors (TAFs), as NSC identity genes in Drosophila. We found that depletion of NSC-TAFs results in decreased NSC clone size, reduced proliferation, defective cell polarity and increased hypersensitivity to cell cycle perturbation, without affecting NSC survival. Integrated gene expression and genomic binding analyses revealed that NSC-TAFs function with both TBP and TRF2, and that NSC-TAF-TBP and NSC-TAF-TRF2 shared target genes encode different subsets of transcription factors and RNA-binding proteins with established or emerging roles in NSC identity and brain development. Taken together, our results demonstrate that core promoter factors are selectively required for NSC identity in vivo by promoting cell cycle progression and NSC cell polarity. Because pathogenic variants in a subset of TAFs have all been linked to human neurological disorders, this work may stimulate and inform future animal models of TAF-linked neurological disorders.
Hyperspectral imaging of the degradation of meat and comparison with necrotic tissue in human wounds
Authors: Holmer Amadeus , Homberger Christoph , Wild Thomas , Siemers Frank
Published: April 2019

The objective evaluation of scattering tissue and the discrimination of tissue types is an issue that cannot be
solved with colour cameras and image processing alone in many cases. Examples can be found in the determination of
freshness and ageing of meat, and the discrimination of tissue types in food technology. In medical applications tissue
discrimination is also an issue, e.g. in wound diagnostics. A novel hyperspectral imaging setup with powerful signal
analysis algorithms is presented which is capable of addressing these topics. The spectral approach allows the chemical
analysis of material and tissues and the measurement of their temporal change. We present a method of hyperspectral
imaging in the visible-near infrared range which allows both the separation and spatial allocation of different tissue types
in a sample, as well as the temporal changes of the tissue as an effect of ageing. To prove the capability of the method,
the ageing of meat (slices of pork) was measured and, as a medical example, the application of the hyperspectral imaging
setup for the recording of wound tissue is presented. The method shows the ability to discriminate the different tissue
components of pork meat, and the ageing of the meat is observable as changes in spectral features. An additional result of
our study is the fact that some spectral features, which seem to be typical for the ageing of the meat, are similar to those
observed in the necrotic tissue from wound diagnostics in medicine.

History and Prospects of Proton Therapy
Authors: Хорошков В. , Khoroshkov V.
Published: April 2019

Purpose: Presentation of the history, status and prospects for the development of proton therapy. Material and methods: The history of proton therapy (PT) is divided into two periods. The first one – the experimental period lasted since 1954 to 1990, when proton therapy was carried out at the ten facilities in physical institutes. The research accelerators and the horizontal proton beams with a fixed direction are used. The second period is from 1990, when the first clinical proton center was commissioned in a multi-field hospital in the city of Loma Linda, USA. In the first period, the necessary technical tools were developed and the advantages of using accelerated protons in remote radiation therapy formulated by R. Wilson in 1946 were confirmed on a limited (about 9,000) patient population: halving the radiation load on the healthy tissues surrounding the tumor and on the organism as a whole compared to γ- and electron irradiation and high dose gradients at the borders of the dose distributions and the tumors. This allows to increase the dose in the tumor (target), increase the probability of the tumor resorption and at last to irradiate tumors, including small sizes, located near critical organs and structures. By 1990, in three experimental centers in Russia (JINR, ITEP, PNPI) accumulated about 30 % of world clinical experience. Today, more than 70 multi-cabin and several single-cabin clinical based proton therapy centers operate in the world. Almost all centers are equipped with gantry installations for PT for 95 % of patients. Today proton therapy is indicated and is used for the treatment of 10–15 % of all malignancies of cancer incidence structure. Results: Healthcare in Russia needs 10–15 multi-cabin proton (and ion) centers. Currently, there are one experimental PT center in the JINR, where up to 100 patients are exposed pea year. The modern proton center was commissioned at the Medical Institute Sergei Berezin in St. Petersburg with two gantry of company Varian. The IBA proton center in Dimitrovgrad is expected. The single-cabin proton complex of domestic production has been operating in Obninsk since 2017. 20th-century technologies and the horizontal beam (without the possibility of its rotation) are used in this complex for treatment of patients with small head and neck tumors. Conclusion: Equipping the Russian health care facilities with proton therapy facilities is inevitable. Russia will buy them worldwide for decades, like almost all types of high-tech medical equipment, are bought today, or can produce them locally. All the prerequisites needed for production (rich physical – technical experience, scientific and industrial potential) are available.

Purpose: Investigation of the dose–time–effect dependency of the behavior of mice and rats after irradiation with accelerated protons and comparison of these data with the morphological changes in the hippocampus and the cerebellum of rodents.

Material and methods: Experiments were performed on outbred adult female ICR mice (CD-1), SPF categories, body weight 30–35 g, of the age of 10 weeks – total number 61 animals, and on 39 male Sprague Dawley outbred rats weighing 190–230 g, aged 6.5–7.5 weeks. The animals were irradiated with accelerated protons with energy of 70 MeV on the medical beam of the phasotron of the Joint Institute for Nuclear Research (Dubna). Mice were placed in individual containers and irradiated 4 ones at a time. Irradiation was performed in a modified Bragg peak at doses of 0.5; 1; 2.5 and 5 Gy in caudocranial and craniocaudal direction. Rats were divided into 2 groups: intact control and group irradiated with 170 MeV protons at a dose of 1 Gy, dose rate of 1 Gy / min in the craniocaudal direction. The behavioral responses of experimental animals were tested in the Open Field test on days 1, 7, 14, 30, 90 in rats and on days 8, 30, and 90 in mice. Quantitative analysis of the dilution of Purkinje cells in the rat cerebellum was made, as well as morphological changes in the rat hippocampal neurons. It was shown a development of structural changes after irradiation with protons in neurons of different severity at different times after exposure: after 30 and 90 days.

Results: In the period of 1–8 days after proton irradiation of mice and rats in non-lethal doses (0.5–5.0 Gy), there is a dose-independent decrease in the main indicators of the spontaneous locomotor activity of rodents.

By the 90th day after irradiation, there is a clear tendency to normalize the indicators of OIR in all groups of irradiated animals, while the ES remains elevated.

Disruption of motor activity of rodents irradiated with protons in the early period and its relative normalization in the late post-irradiation period occur on the background of an increased number of morphologically altered and dystrophic neurons in the hippocampus and rarefied of Purkinje cells in the cerebellum.

Conclusion: The complex hierarchical structure of the central nervous system, the dependence of its function on the state of the whole organism and its hormonal background, as well as on the state of the blood supply and other factors, along with its high plasticity, require complex physiological, morphological and neurochemical approaches in analyzing the radiobiological effect of corpuscular radiation, taking into consideration the unevenness in dose distribution during irradiation.

Published: April 2019

Purpose: Due to the necessity of improving the education of medical workers it is vital to conduct a review of the current state of training for work associated with the use of high-tech equipment and the use of radiopharmaceuticals for nuclear medicine.

Results: To ensure the availability of modern, high-quality medical care, oriented to world standards, it should be considered that the necessary conditions are based not only on the development of medical science and technology, material and technical equipment, but also on the provision of highly qualified personnel with a certain set of competencies.

Currently, the training and professional development of personnel for this area is carried out at all levels of vocational education: secondary and higher in accordance with the Lists of specialties and areas of vocational education. At the same time, the issues of developing and approving relevant professional standards and Federal state educational standards (FSES) for the needs of nuclear medicine remain unsolved, which in turn is one of the factors that reduce the demand for specialists in this field in the labor market.

At the same time, the issues of developing and approving relevant professional standards and FSES for the needs of nuclear medicine remain unsolved, which in turn is one of the factors that reduce the demand for specialists in this field on the labor market.

The personnel crisis is overcome due to the implementation of additional professional programs and practical training at the bases of leading scientific, clinical and educational institutions that are leaders in the field of nuclear medicine and radiopharmaceuticals.

Conclusion: In order to address the shortage of personnel for such a booming industry, a clear coordinated plan is needed, which would include systematic measures to train personnel both at the undergraduate level and to improve already prepared specialists. In addition, it is necessary to prepare a pool of highly qualified faculty for training specialists of a new formation. It is necessary to create federal educational standards taking into account that the current state of medical science and on the basis of professional standards. Work in this direction can be successful only if all stakeholders are actively involved: educational organizations, the professional community and government structures.

At the same time, it is an obvious fact that, before the adoption of professional standards and the FSES, the available experience of leading scientific and educational organizations in the training of specialists should be adopted and they should receive support and development.
Processes of Value Co-creation at a Tourist Accommodation
Authors: Oxenswardh Anette
Published: April 2019

Purpose: This paper aims to study how a pair of hosts for one bed and breakfast establishment and their guests create value for the visit by communicating and interacting with each other on the island of Gotland.Methodology/Approach: A case study was conducted on one single Bed and Breakfast (BnB) accommodation. An interview and a Questionnaire study were performed.Findings: The study shows that there are several processes involved in the co-creation of values between visitors and hosts. Co-creation processes begin already when visitors are planning their visits to the island. Their expectations are created while choosing their accommodation type, often done online on different websites. Pre-information about the chosen BnB accommodation contributes to visitors’ expectations and image of the object, which can be seen as a part of their identities. In the physical meeting with the accommodation and the hosts and other guests, the co-creation process is strengthened. There are processes of participation, communication, creation of meaning for the stay, processes of trust and responsibilities which all together create a common culture which in turn contributes to co-creation of values for both parties. These processes also take place between guests. The processes are furthermore dependent on meaning-making and sensemaking processes. This all together generate knowledge about the destination and the values that enhance the positive experience of the visits. It also creates knowledge for the hosts about how they can develop their service to achieve increased customer satisfaction. Finally, these skills can be valuable for the continued planning and development of the tourism industry.Research Limitation/implication: The study is limited to a one single BnB accommodation with its hosts on the island of Gotland in Sweden.Originality/Value of paper: The study makes a contribution to the knowledge of processes of co-creation values by exploring how some visitors and their hosts experienced visits to the island. The study can help bridging the gap in the views and actions on co-creation of values among visitors and those who are visited.

Authors: Zimon Dominik , Zimon Grzegorz
Published: April 2019

Purpose: The main purpose of the paper was to determine the impact of an implementation of the quality management system according to ISO 9001 on the improvement of processes related to the management of liabilities to suppliers.Methodology/Approach: The research covered 38 Polish small trading enterprises operating in two group purchasing organizations. The research period concerned the years 2014-2016. The surveyed enterprises were divided into those that implemented standardized quality management systems (10 organizations) and the ones that do not use such solutions (28 organizations). Next, the analyses were made and the results obtained by enterprises associated in particular groups were compared.Findings: The obtained results confirm that more effective management of liabilities towards suppliers can be observed in enterprises applying appropriate system procedures. This group includes long-term liabilities and the turnover ratio of short-term liabilities in days achieves lower results than results for enterprises that did not introduce standardized quality management systems.Research Limitation/implication: Due to a small research sample, the obtained results can only be considered as an introduction to further research and deliberations.Originality/Value of paper: The considerations discussed in this article concern a relatively rarely discussed subject matter in the literature.
Role of interleukin 1 in the development of atherosclerosis
Authors: Nasonov E. L. , Popkova T. V.
Published: April 2019

Atherosclerosis is now considered as chronic inflammatory vascular disease connected to «pathological» activation of innate and adaptive immunity, characterized by lipid deposition, leukocyte infiltration and proliferation of vascular smooth muscle cells. Subclinical (low grade) inflammation plays fundamental role at all stages of atherosclerotic process progression and determines cardiovascular catastrophes development and mortality. Proinflammatory cytokines including interleukin (IL) 1, IL6, tumor necrosis factor α (TNFα), IL17, IL18, IL27, IL33, IL37 tightly interacting within cytokine network occupy an important place among numerous mediators participating in immunopathogenesis of atherosclerosis and rheumatoid arthritis. IL1β playing an important role in the development of many acute and chronic immunoinflammatory diseases attracts particular attention. IL1β significance in the development of atherosclerosis is determined by many mechanisms including procoagulant activity, enhancement of monocytes and leucocytes adhesion to vascular endothelium, vascular smooth muscle cells growth and others. Fundamental role of inflammation in the development of atherosclerosis is well proved in investigations of anti-atherosclerotic effect of canakinumab. Randomized placebo-controlled trial CANTOS (Canakinumab ANti-inflammatory Thrombosis Otcomes Study) assessing efficacy of canakinumab as new tool for secondary prophylaxis cardiovascular complications in general population of patients with severe atherosclerotic vascular damage. CANTOS results in combination with accumulated in rheumatology data on cardiovascular effects of anti-inflammatory drugs are of great importance for personification of approach to secondary prophylaxis of caused by atherosclerosis cardiovascular complications. They also contribute to the development of inflammatory theory of atherosclerosis pathogenesis in the whole.
Crisis Management in South Korea and the Hegemonic Strategy of the Chaebols
Authors: Kim Kyung-Pil
Published: April 2019

In the Republic of Korea, chaebols—diversified and large-scale conglomerate forms of capital governed dynastically by an owner and the owner's family—have grown quickly, dominating the Korean market and substantially contributing to the Korean economy since their structuring in the 1970s. Some chaebol affiliates have grown into global economic powers within a mere thirty to forty years. However, the fast growth of the chaebols in Korea has also been associated with crises and in trying to manage these crises chaebols have not only changed the ways in which they accumulate capital, they have sought to establish hegemony over civil society.
The Debs Way
Authors: Huberman Leo
Published: April 2019

This reprise of "The Debs Way"—the text of an address Huberman delivered at the Debs Centennial Meeting held at the Fraternal Clubhouse in New York City on November 28, 1955—not only reminds us of the importance of Eugene Debs to the history of socialism in the United States, but also brings out some of the core beliefs of Huberman's own approach to socialism. Today's conditions are of course vastly different from when Huberman wrote this, more than sixty years ago. There is now a resurgence of the left in the United States, but the basic principles that Huberman derived from Debs remain relevant.

Pare bay is one of the areas of significance which is utilized for port services, stevedoring, oil distribution, regional industrial development, aquaculture, cultivation and settlement systems. Pare Bay potentially has a good prospect for a gigantic development. Whilst, a very dangerous threat is pollution, especially heavy metal pollution and water quality degradation. This study aims to determine the current condition of heavy metal concentrations and its distribution on surface waters of Pare Bay. Heavy metals were analyzed using AAS (Atomic Absorption Spectrophotometry) in which it has a minimum detection limit reached 0.001 ppm so that the heavy metal concentration can be well-determined. Hg concentration is higher in the surface ranged 0.01-0.1 mg.l-1. Cd concentration ranged from 0.018-0.083 mg.l-1. Cu concentration ranged from 0.043-0.078 mg.l-1. Pb concentration ranged from 0.111-2.692 mg.l-1. Zn concentration ranged from 0.004 - 0.112 mg.l-1. Heavy metals content in Pare Bay exceeds the standard quality established by Ministry of Environment. It potentially harms the marine life which indirectly reduces the function value of Pare Bay as a center of maritime in the South Sulawesi. Water quality condition play a role in inducing the toxicity level of heavy metals in the Pare Bay. So that this area need to be monitored the water quality sustainably.

Published: April 2019

In the period 2012-2017 we investigated the occurrence of indigenous species of predatory mites in different cultivated plants in Slovenia. In a comprehensive study we confirmed the occurrence of the following predatory mites: Amblyseius andersoni (Chant, 1957), Euseius finlandicus (Oudemans, 1915), Euseius gallicus (Kreiter & Tixier, 2009), Euseius stipulatus (Athias-Henriot, 1960), Kampimodromus abberans (Oudemans, 1930), Neoseiulus californicus (McGregor, 1954), Paraseiulus triporus (Chant & Shaul, 1982) and Phytoseius horridus (Ribaga, 1904). In the paper all seven species are presented, but for the field of biological control A. andersoni, E. gallicus and N. californicus are the most interesting species. The first two of them are already on the List of indigenous organisms for the purpose of biological control, while the third will be placed into it in the near future. All three of them have a great potential in biological control, since they can be found in different host plants.

This study was carried out in order to study the response of corn cultivars to row spacing and weed interference at the Research Farm of Agricultural and Natural Resources Faculty, Razi University, Kermanshah, Iran in 2011. The experiment was a split block factorial based on a randomized complete block design with three replications. Factors consisted of three corn cultivars ('KSC 704', 'Simon' and 'Maxima') and three plant row spacings (45, 60 and 75 cm) under weeded and un-weeded conditions for all of the growing season. Results indicated that for all three corn cultivars, the highest weed dry mass occurred in the row spacing of 75 cm. Weed interference throughout the growing season reduced corn grain yield by 20 %. This condition also significantly decreased corn yield components except the 100-seed mass. Increasing plant row spacing increased weed density, while decreased corn yield by 16.5 %. Corn cultivars were significantly different in terms of the number of seed per ear and 100-seed mass, as 'KSC 704' and 'Simon' showed the highest values for these yield components, respectively. However, the number of ear per plant and grain yield were not significantly different between the corn cultivars under study.

Published: April 2019

Very few studies were carried out to investigate the aphids attacking grapefruit. These pests cause considerable damages on citrus trees and other crops. This paper reports on the fluctuations of aphids on grapefruit in the region of Skikda (Algeria). From January 2012 to December 2013, monthly surveys were performed to measure the abundance of aphids recorded on 16 leaves of grapefruit. Through this study, five aphid species were identified, among them Aphis spiraecola Patch, 1914 was the most numerous. Besides, we noticed that the populations of aphids reached high levels many times within the year. However, the most important densities were recorded in spring and autumn.
