Development of soft commodity derivative market in function of the risk management in CEE

This aim of this paper is to analyse possibilities and potential effects of soft commodity derivative market on the development of risk management practice within the CEE. Agricultural producers and other participants in the soft commodity market in CEE are lacking local commodity market. As a consequence, they are relying on hedging strategies on remote derivative markets that results in basis risk. The local soft commodity derivative market with delivery in CEE ports could significantly improve the risk management practice. One of the most important barriers in developing commodity derivatives market is market liquidity. Joint commodity market between different commodity exchanges in the CEE could lead to increase of necessary liquidity. Attempts to develop commodity derivative markets in individual countries within the region were proven to be inefficient lacking the volume of trade. Methodology used in this paper is based on relevant literature review, consultation with experts in commodity tradeand market participants and descriptive statistics applied in order to determine grain price volatility. Results of the research indicate that grain price volatility is high causing the need for application of hedging strategies at the commodity exchanges markets. Second, new EU common regulative is providing improved framework for joint commodity exchange clearing by single clearinghouse. Established market with delivery on Black See ports is of special importance for regional stakeholders

Exploring critical factors affecting sign language knowledge and motivation for sign language learning in nurses: A cross-sectional study

Introduction: In times when the term inclusion, rights of patients, and the patient as a subject in health care are used more often, the limited availability of written material or sign language interpreters at health services is still a key barrier to health services for people who are hearing-impaired. The aim of this study is to examine nurses’ knowledge of communication skills with hearing-impaired patients, their preferred methods, and the possibility of using translation services. Methods: The study was cross-sectional, and data were collected in September–October 2019. The study included 407 nursing students. A demographic data form and questions divided into three parts, namely, communication skills (six questions), communication methods (three questions), and interpretation services (five questions), were used to collect data. Data were analyzed with descriptive statistics. Results: The questionnaire was administered among 424 students, and total of 407 students completed the questionnaire. Most of the respondents were female (320 [78.6%]) with 0–5 years of work experience (227 [55.8%]) in the tertiary level of healthcare (184 [45.3%]). The results showed that 326 (80.1%) of the respondents encountered a person with some form of hearing impairment during their work. Sign language was used by 56 (13.8%) of the respondents, but 74 (18.14%) nurses did not communicate when meeting with hearing-impaired patients. Two-thirds of the respondents never had the opportunity to learn sign language, and 43 (10.54%) respondents would choose an official interpreter as support. Male respondents were aware of the importance of communication with hearing-impaired patients and the use of an application for pain assessment (p < 0.05). No statistically significant difference was observed regarding the department in which the respondents work (p > 0.05). Conclusion: The results of the study showed insufficient knowledge and skills of nurses to communicate with hearing-impaired people

Application of Sentinel Lymph Node Biopsy in Cutaneous Basosquamous Carcinoma

Basosquamous carcinoma of the skin is a relatively rare cutaneous neoplasm that has significant metastatic potential and a metastatic rate greater than that of basal cell and squamous cell carcinoma. We describe the use of lymphatic mapping and sentinel lymph node biopsy in a 63-year-old man after identification of basosquamous carcinoma. Sentinel lymph node biopsy, which is a standard tool to detect regional lymphatic metastasis in cutaneous melanoma, has been rarely employed to detect lymphatic metastasis of basosquamous carcinoma. The approach was successful in detecting a regional lymphatic metastasis of two nodal basins with minor morbidity. Sentinel lymph node biopsy may be useful for certain high-risk lesions of basosquamous carcinoma

A unique case of hereditary bilateral segmental neurofibromatosis on the face

Segmental neurofibromatosis is a rare clinical finding generally with no family history and facial involvement. There are four subtypes of segmental neurofibromatosis: true segmental, localized cases with deep involvement, hereditary segmental and bilateral segmental neurofibromatosis. Here we report three patients from the same family (father, son and granddaughter) with segmental bilateral neurofibromatosis on the face. This form hasn't noticed in the literature

Soil tillage impacts on nutritional status of soybean

Soybean were grown under field conditions on chernozem soil for four growing seasons (from 2002 to 2005). Three treatment of soil tillage were applied as follows: a) conventional tillage, b) reduced tillage (diskharrowing instead of ploughing) and c) no-till (zero-tillage). In general, the characteristics of growing season (the factor „year“) were more influencing factor of soybean nutritional status (aerial part in stage of full-developed pods) in comparison with the soil tillage. In our study, low influences of applied soil tillage treatments on nutritional status of soybean were found because significant differences on soybean composition were found only for four (Cu, Cr, Sr and Ba) from total 20 analysed elements. For example, conventional tillage resulted by the higher plant Cu (by 15% and 18% in comparison with DH and NT, respectively), and the lower plant Sr (by 12% and 16%, respectively) and Ba (by 26% and 23%, respectively), while under DH conditions by 22% lower plant Cr was found. Main nutrient status (P. K, Ca, Mg, S...) were independent on soil tillage. For this reason, usual fertilization practice is recommended for possible application of soil tillage reduction under conditions of calcareous chernozem

Does incomplete excision of basal cell carcinoma of the eyelid mean tumor recurrence?

INTRODUCTION: Basal cell carcinoma is the most common tumor of the eyelid. In this region, reconstruction is complex and damage to healthy tissue should be minimal. Objective: To define the relationship between margin clearance at excision and the recurrence rate of basal cell carcinoma of the eyelid. METHODS: This prospective study was conducted with 111 patients submitted to surgery for basal cell carcinoma of the eyelid between 2001 and 2003 and followed up for a period of five years. The patients were evaluated according to age, tumor site, recurrence rate and margin clearance at excision. RESULTS: No significant association was found between incomplete tumor excision and recurrence except in patients under 56 years of age, female patients and in the case of tumors of the medial canthus. CONCLUSION: A risk of recurrence in incompletely excised basal cell carcinomas of the eyelid was only confirmed in younger patients, females and for tumors of the medial canthus
