Lettuce (Lactuca sativa) is vegetable crop that consumed part of the leaf and harvested at a phase of vegetative. Nitrogen play important role in growth at phase of vegetative. Nitrogen in spacious have the character of easy to lose because of leaching. Increasing yield of lettuce can be done byimproving Nitrogen synchronization, that is precisely usage moment with ready moment of N during and amount of its. The research was aimed to study of the pattern nitrogen requirement for lettuce crop, ready pattern of nitrogen by Tithonia diversifolia and design nitrogen synchronization model between lettuce crop with green manure of T. diversifolia. The research were divided in two phases that are phase research 1: Dynamic modeling for nitrogen synchronization on lettuce cultivation by green manure of T. diversifolia, and phase research 2: Fertilizer technology of high nitrogen synchronization on lettuce cultivation by green manure of T. diversifolia. The result of phase research 1 (first year research) shows that dynamic model of N requirement by lettuce crop, release and availability model of N by T. diversifolia and synchronization model of N between requirement of N lettuce with release and availability of N by T. diversifolia. The dynamic model indicate that giving 10 t ha-1 of T. diversifolia which given 2 weeks before transplanting at lettuce crop can support high result and growth because happened good synchronization of N.

In an attempt to bridge the gap between architectural/interior design practice and education, ‘atmosphere’ as a prolific contemporary architectural debate in practice and theory is covered by the experiment of ‘Staging Poe’ carried out as a first year Design Studio through the study of Edgar Allen Poe’s selected poems. Poe’s 1846 text of ‘The Philosophy of Composition’, unfolding his analytical method of writing and emphasis on “effect” in poetry, provides a ground for experimenting with facets of materiality and structuring the studio. Aiming to cultivate intuitive design experiments of students into informed processes in hybridizing conceptual/textual and material/sensual aspects, studio is structured in two phases. In the first phase, “materialization”, idiosyncratic interpretations of students from words to materials with a focus on tectonic experiments and haptic experiences are sought in between materializing and dematerializing processes. In the second phase, the “atmospheric”, emphasis on dematerialization of the perception of materials through tools, such as light, color and sound is exercised to transform the object into a performance stage. Outcomes of the studio on aspects pertaining to material and materialities in creation of the immaterial that is the atmosphere is followed and evaluated through responses of students’ weekly reports.

Empirical studies have shown that explicit instruction leads to the improvement of perception (e.g. Strange and Dittman 1984; Jamieson and Morosan 1986; Cenoz and García Lecumberri 1999) and oral production (e.g. Couper 2003; Derwing and Munro 2005; Smith and Beckman 2005). Nonetheless, it is necessary to test different types of activities intended for the explicit teaching of pronunciation. This action-research study aims to test the efficacy of a reading aloud task with a noticing and an awareness component in the teaching of pronunciation, and to gauge learners’ beliefs regarding the use of this learning tool. Twenty first-year students of the BA in English Studies at the University of the Basque Country participated in the investigation. Ten written texts were selected by the instructors in order to practice reading aloud for ten weeks. Students went through two phases when doing this task in class: noticing and awareness. They were tested on articulation of sounds, stress placement and intonation through two different texts at two different times. Students were also administered a questionnaire to analyze their opinions regarding the usefulness of this learning task. The assessment of the recordings revealed that learners obtained better means in the case of the second text analyzed. Similarly, the analysis of the responses given to the questionnaire indicated that students considered the reading aloud task a good instrument to improve their pronunciation in English.

Abstract Aim. This study aimed to evaluate a new project of the Slovene Ministry of Health - the Family Medicine Model Practices (MPs) Project in Slovenia, and to show its effectiveness in the management of asthma and COPD by family medicine practice teams, consisting of a family physician, a nurse practitioner and a practice nurse. Methods. A total of 107 family practices with 203122 patients joined the project during the first year of its initiation. The effectiveness of the program in disease management was analysed in two phases according to the registration of family practices. The number of patients registered and the number of asthma and COPD patients (existing and newly detected) by model practice teams were being reported. Descriptive analyses were used to describe the study populations. Prevalence by diseases and phases was established after the initial round of data collection. Chi square (χ2) test was used to analyse the difference between the phases. Results. The frequency of asthma was 2.12%, while the frequency of COPD was 1.15% throughout the study period. For both diseases, more than 30% of patients were newly diagnosed. Conclusions. The project of implementing Family Medicine MPs in the area of COPD has given first positive results and the project is still ongoing to its full implementation.

Abstract Background There is an increasing number of studies that infectious diseases consultations improve patients’ outcomes, but few studies have investigated the quality of consultations. The aim of this study was to identify important skills and attitudes for consultants to improve the quality of consultations. Methods We conducted our research in two phases: a preliminary survey (May 1 to 14, 2020) and the main survey (June 1 to 14, 2020). As a preliminary survey, first-year postgraduate residents at St. Luke’s International Hospital in Tokyo, Japan, were first asked an open-ended question about the types of skills and attitudes that are important for consultants. After eliminating duplicate answers, there were 19 skills and attitudes in total. In the main survey with residents who completed their residency training at our institute, from 2014 to 2018, and current residents (2019–2020), we first asked them about their demographic characteristics (gender, years of postgraduate education, and type of specialty). Then, they answered how important each skill and attitude are for consultants. All 19 items were scored on a seven-point Likert scale that ranged from 0 (completely disagree) to 6 (totally agree) (Figure 1). Cronbach’s alpha confirmed the internal consistency of the questionnaire items. Principal component analysis and exploratory factor analysis were performed. Figure 1. Skills and attitudes required in consultants according to residents Results The survey included 107 individuals (61.1%, 175 potential participants). The median postgraduate years of education were four (interquartile range: 2-5), and 64.5% were men (n = 69). Seven key elements for consultants were identified and termed Willing CONSULT. These included (1) willingness (willingness to accept consultation requests), (2) contact (easy access to consultants), (3) needs (consideration of consulters’ needs), (4) suggestions and support (providing clear recommendations and suggestions, following up on the patients, and supporting the consulters continuously), (5) urgency (considering the situation’s urgency and responding appropriately), (6) learning opportunities (providing teaching points), and (7) text (writing medical records appropriately and quickly) (Figure 2). Conclusion We propose Willing CONSULT, which are important skills and attitudes for consultants. Disclosures All Authors: No reported disclosures

A 2-year field experiment was carried out in a Mediterranean environment to study the effects of vetch (Vicia sativa L.) residue management strategies incorporating green manure (GM) using a roller-crimper (RC) and different organic fertilizers (municipal solid waste compost, anaerobic digestate, and a commercial organic fertilizer) on organic zucchini (Cucurbita pepo L.) yield and quality. Zucchini yield was influenced positively by the vetch residue management strategy, although the response was significantly different between years. The vetch cover crop increased marketable zucchini yield in the first year by 46.6% compared with the fallow (FA) treatment, indicating that this fertility-building crop could reduce off-farm nitrogen (N) fertilizer input for subsequent crops. Averaging over 2 years of the experiment, marketable zucchini yield increased by 15.2% and 38% with the RC mulch and GM plow-down, respectively, compared with the FA treatment, although differences were significant in the first year only. The application of organic fertilizers in vetch management plots increased marketable zucchini yield by 21.8% in the first year compared with the unfertilized control. This result is particularly relevant, because organic fertilizers were applied at ≈50% of the normal application rate for zucchini after taking into account biological N fixation attributable to the vetch. The concentrations of soil mineral N at harvest were 19, 27, and 28 mg·kg−1 for the RC, FA, and GM treatments, respectively. These mineral N concentrations indicated that a portion of applied organic fertilizer N, and N attributable to vetch (GM and RC), remained in the soil at harvest, suggesting the potential for leaching, which should be taken into account in the overall fertilization program. These research findings suggest that effective vetch cover crop management and the application of organic fertilizers can improve yield and quality of organically managed zucchini.

Abstract A field experiment was carried out in central-eastern Poland (52°06’N, 22°55’E) to investigate the effect of a sunflower catch crop used as green manure sown on three different dates (21st July, 4th and 18th August) on sweet corn yield and growth. The ‘Challenger F1’ and ‘Sweet Wonder F1’ corn cultivars were cultivated in the first year following organic fertilization. Sunflower was plowed in the third week of October. The effect of the catch crop’s green manure was compared to farmyard manure applied at a dose of 40 t ha-1 as well as a control without organic manuring. The biomass quantity and the amount of macroelements absorbed with the sunflower catch crop sown on the 21st of July was similar to the quantity absorbed with farmyard manure applied at a rate of 40 t ha-1. The quantity of organic mass and macroelements absorbed with the sunflower sown on the 4th of August was smaller by 20%, and by 50% for the 18th of August set, compared with the corn treated with farmyard manure. The effects of farmyard manure and sunflower catch crop sown on the 21st of July on the yield were similar. The marketable yield of cobs of corn plants cultivated following farmyard manure treatment and catch crop sown on the 21st of July amounted to 12.6 and 12.4 t ha-1, respectively. An application of sunflower sown as a green manure on the 2nd and 3rd date prior to corn cultivation decreased marketable cob yields by 8% and 25% as compared to the farmyard manure. The corn cobs cultivated following the sunflower sown on the 21st of July and treated with farmyard manure had the greatest mass. The corn cobs cultivated with farmyard manure were characterized by the highest biological productivity (72.1%); similar was the cob production of corn cultivated with catch crops sown on the 21st of July and the 4th of August. The ‘Challenger F1’ and ‘Sweet Wonder F1’ yields were similar. ‘Challenger F1’ produced cobs with higher mass whereas ‘Sweet Wonder F1’ produced cobs characterized by greater biological productivity.

The work consisted of the morpho agronomic evaluation of coffee crop under the influence of intercropping with different types of green manures. The experiment was carried out in the Southern Region of the State of Espírito Santo, Brazil. The experimental plot consisted of five plants per experimental unit, using the clone "Incaper 8142" Conilon Vitória, intercropping with different types of green manure plants, which were: guandu beans (Cajanus cajan), pig bean (Canavalia ensiformis), mucuna preta (Mucuna Pruriens) and Mexican margaridão (Tithonia diversifolia) in addition to a control treatment without green manure. The planting consisted of rows adjacent and located in the “upper interline” meaning is not clear of the coffee crop. The morpho agronomic characteristics evaluated were: plant height, orthotropic branch diameter, plagiotropic branch diameter, number of leaves, number of nodes, number of orthotropic branches, number of plagiotropic branches and productive nodes e productivity green coffee kg/ha, besides the main dependent: The characteristics of greatest direct contribution were number of nodes and number of productive nodes. The species of green fertilizer Mexican Margaridão (Tithonia diversifolia) provided a negative effect on the main variables related to production, and is not recommended for interplanting with robusta coffee.

With prevalence rates of postnatal depression (PND) as high as at least 7%, there was a need for early detection and intervention of postpartum mental illness amongst Singaporean mothers. This is a report on the first year results of our country's first PND Intervention Programme. The programme consists of two phases: (1) postpartum women were screened with the Edinburgh Postnatal Depression Scale and provided appropriate care plans; (2) individualized clinical intervention using a case management multidisciplinary team model. Screening for PND was generally acceptable, as 64% eligible women participated voluntarily. Nine percent (126) were identified as probable cases from 1369 women. Forty-one women accepted intervention and achieved 78% reduction in the EPDS symptom scores to below the cutoff of 13, 76% had improvement in GAF functioning scores, and 68% had improved health quality scores. Preliminary results are promising, and this intervention model can be replicated.
