The aim of this study was to analyze the effects of strain, density and their interaction on mortality and body weight of broiler chicken raised in the closed houses. The data was obtained from 60 broiler farms in the Central Java province. Three strains were Cobb, CP 707, and Loghman. The density level was classified into three groups:  £10,  >10 to <15, and  ³ 15 birds/m2. Parameters observed were mortality and body weight in the first week to the fifth week (M1, M2, M3, M4, and M5) and (BB1, BB2, BB3, BB4 dan BB5), respectively. Test of significance effect for strain and density was performed using Mixed procedure of Statistical Analysis System (SAS) University Edition V.6p.2. software. The results showed that density was significant (P<0,01) on the first week (M1), their interaction was (P<0,01) on M1 and (P<0,05) on the fourth week (M4), but not significant on body weight. The conclusion from this study there was an interaction between genetic and environment on mortality one week after chick in and nearly harvesting.

OBJETIVO: investigar a qualidade de vida de sujeitos com respiração oral ou oronasal. MÉTODO: compuseram a amostra 49 voluntários, distribuídos em dois grupos: grupo de respiradores orais com 24 sujeitos e grupo de respiradores oronasais com 25 sujeitos, com faixa etária ente 18 e 38 anos de idade, de ambos os sexos. O protocolo utilizado foi o WHOQOL-BREF (versão em português) e o registro e análise dos dados foi realizado pelo sistema Statistical Analysis System. RESULTADOS: os resultados obtidos foram submetidos aos testes de qui-quadrado de Mantel-Haenszele análise de variância. A qualidade de vida dos respiradores mistos se revelou inferior nos domínios ambiental, físico e psicológico em relação aos respiradores orais. CONCLUSÃO: com a detecção das diferenças obtidas, o estudo chama a atenção para a necessidade de aprofundar investigações sobre o perfil dos respiradores oronasais e sua relevância. Para que condutas como desconsiderar o grupo de respiradores oronasais ou agrupá-los como respiradores orais não sejam adotadas de forma inadequada.

O estudo foi conduzido para avaliar intervalo de partos (IDP) na raça Nelore, utilizando 578 dados de intervalo de partos de animais criados em regime de pasto, no período de 1988 a 1996. Para as análises estatísticas dos dados, foi usado o Programa SAS (Statistical Analysis System). Foram incluídos no modelo o efeito aleatório do pai da vaca, os efeitos fixos de grupo genético da cria anterior, de ano do parto anterior e do mês do parto anterior e as interações entre grupo genético anterior e mês do parto anterior, grupo genético anterior e ano do parto anterior, além da idade da vaca ao parto como covariável. O IDP foi influenciado pelo pai da vaca e pelo ano do parto anterior. A média estimada por quadrado mínimo e seu respectivo erro-padrão (EP) e coeficiente de variação (CV) foram 431,83 ± 142,76 dias e 33,06%, respectivamente. O intervalo de partos, além do efeito de pai, sofreu influência de ambiente. O desempenho reprodutivo do rebanho estudado, para as condições de clima tropical, pode ser considerado como satisfatório, estando de acordo com os parâmetros obtidos por outros autores em diferentes regiões.

Background: The new role as professional nurse can be a difficult transition for the new qualified nurses. During this time, factors such as not being well prepared, working without supervision and a lack of guidance can be the result of a difficult transition.Objectives: The purpose of this study is to assess the perceptions of newly qualified nurses on the guidance given by their preceptors towards becoming experts in practice at a Level II regional hospital in the Western Cape.Method: A non-experimental quantitative descriptive design was followed. Collection of data was done by means of a questionnaire, designed by the researcher, using a cross-sectional research method. Non-probability sampling produced a sample of 162 nurses comprising registered nurses (48.2%), enrolled nurses (32.7%), and enrolled nursing auxiliaries (19.1%). Statistical analysis was performed using the Statistical Analysis System (SAS), version 9.3.Results: The results of the research study indicated that respondents had more positive experiences than negative ones. The respondents indicated that for the role and characteristics of the preceptor, expectations were met for knowledgeability, professionalism and contribution to team work. Furthermore, the results indicated that the respondents would recommend preceptorship.Conclusion: Preceptorship is one of the major interventions available to support newly qualified nurses by easing the transition from student to practicing nurse and reducing the theory-practice gap. The findings emphasised the importance of ongoing support programmes for nurses after obtaining a new qualification or/and being a new nurse.

The city of Surakarta is one of the cultural and historical tourist destinations that continues to develop in Indonesia. The trend of an increase in the number of tourists in 2016-2018 has led to the emergence of many accommodation facilities in the city of Surakarta. Differences in location characteristics in each accommodation facility will affect tourists in choosing accommodation facilities. This study aims to determine the characteristics of the location of accommodation facilities chosen by domestic and foreign tourists in the city of Surakarta, as well as the relationship between the characteristics of the location of accommodation facilities with the characteristics of tourists based on the age and place of origin of tourists. This study uses a spatial comparison analysis method and uses a chi-square statistical analysis to see the relationship between variables, such as the characteristics of the location of accommodation facilities and characteristics of tourists. The results of this study indicate that the location characteristics of the accommodation facilities chosen by foreign and domestic tourists are different. Foreign tourists tend to choose star hotels, while for domestic tourists the choice varies, namely star hotels and non-star hotels. In addition, there is a relationship between the characteristics of domestic tourists with the characteristics of the location of selected accommodation facilities, while for the characteristics of foreign tourists there is no relationship with the characteristics of the location of selected accommodation facilities.

El Gobierno Federal ha incentivado la práctica de seguros agrícolas con subsidios a los productores usuarios de estos servicios, pero la forma en que han sido canalizados los gastos para fortalecer la práctica de los seguros no ha sido suficiente para lograr, sobre todo entre productores pequeños, generalizar esta práctica. El objetivo de esta investigación fue proponer un modelo de seguro agrícola, quien lo adquiere recibe beneficios adicionales a los que normalmente existen y se obtienen en los seguros tradicionales, en el año 2018. La metodología parte del principio teórico de los ciclos económico de Burns y Mitchell el cual es uno de los primeros estudios de ciclos económicos basado en series de tiempo de Avella-Gómez y Ferguson. Con la técnica estadística de regresión aplicada a datos de producción y rendimientos del cultivo básico, para este caso el maíz blanco, modelado con el programa Statistical Analysis System (SAS). Algunos resultados y conclusiones, observados fueron que a diferencia de los seguros tradicionales, se propone que los montos a pagar por concepto de primas de aseguramiento, se determinen antes de cada ciclo agrícola, con información de campo obtenida por especialistas y técnicos gubernamentales que están más cerca de los productores. Se considera que se deben determinar montos diferentes de prima de seguro por región agrícola de los Distrito de Desarrollo Rural, por cultivo y por régimen hídrico de riego o temporal.
