Productivity Optimization of Screen House Layout Design

The study investigated the optimization of the screen house design to improve the growth productivity of green ornamentals. It focused on the labor-intensive handling operations in order to minimize the time invested in these operations and to maximize the total revenue. The research was performed during 2006–2007 in two modern farms in the central part of Israel. The farms contained 7 and 11 ha of Pitosporum and Aralia screen houses. The various stages of harvesting on each farm were subjected to work studies and time measurements, and a computer simulation model was developed with the ARENA 7™ to find an improved screen house layout. The main goal was to determine the time per stem and hourly output per worker as functions of length of row, distance between rows, distance between plants, work pace, and number of workers. Results show that for the examined cultivars and the present working methods, the best outcome was reached when the row length was the shortest of those examined. There was a decrease of 35% in output when row length increased from 24 to 200 m. Simulation results showed that the best length of a screen house was 24 m. Furthermore, the best width of the screen house was determined as a function of the number of workers and their work pace. In addition, the optimal location of the cart used to transfer the crops to the packaging house was determined

Working planning in packing houses of flowers mixed farms to increase the yield

The study deals with performance improvement in flowers mixed farms.  The farm under investigation is located in the central part of Israel and grows three types of green ornamentals: Pittosporum, Aralia and Aspidistra.  The farm consists of 8 hectares and employs 7 workers.  The annual yield of the farm in 2009 was 3.5 million branches.  The study investigates the working processes of the packing house.  A computer model and work planning management tool was developed using MATLAB.  The model inputs are: flower type and quantity, due date and sales price.  The output is a work schedule.  Results show an improvement of processing time by: 47% for Pittosporum, 19% - 45% for Aralia, and 23% - 54% for Aspidistra

Reproduction Biology Eastern Little Tuna Euthynnus Affinis in the Sunda Strait

Eastern little tuna is small pelagic fish that has high economic value. Fishing effort of the eastern little tuna for the last eight years have also exceeded the optimum level. To ensure the sustainability of the pelagic fish resources, it is necessary to perform the management efforts. This study was to observe reproductive Biology of the eastern little tuna, as one of the necessary information in the management of fishery resources. Fish -samples were collected from the catch of local fishermen in April-August 2015. Based on T test (α = 0,05), the eastern little tuna males and females showed positive allometric growth patterns. Average size of the first time caught fish for the female (308,37 mm) and male (280,63 mm) was smaller than that observed in those first time maturity gonads (ranging 407-408 mm for female and 438-440 mm for male). The eastern little tuna spawn gradually or partially (partial spawner), and have high reproductive potential with fecundity ranged 17.814-560.792 eggs (average fecundity: 109.807) in fish of 285-630 mm body length. The gonad maturity level of the eastern Little Tuna is dominated by Gonad maturity level I and II,(immature). The value of gonad maturity for the female level is about 0,0769-0,6879 and the male is 0,1913-0,3000

The Role of Tourist Tax in the Business of Tourist Agencies in the Republic of Croatia

Turističke agencije dužne su naplaćivati boravišnu pristojbu za sve smještajne objekte u Republici Hrvatskoj. Za taj posao ne dobivaju nikakvu naknadu niti imaju mogućnost zaračunati manipulativne troškove. Izdvajanje neoporezive boravišne pristojbe iz cijena paket–aranžmana predstavlja operativni problem za turističke agencije, ne samo kod prodaje paket-aranžmana iz kataloga i brošura, nego i kod online prodaje paket-aranžmana. Takav način naplate uzrokuje dodatne troškove za turističke agencije najviše vidljive kroz velik broj dodatnih unosa u rezervacijske sisteme, ali i kroz broj dodatnih računovodstvenih transakcija pri plaćanju računa. Potrebne su promjene važećeg Zakona o boravišnoj pristojbi Republike Hrvatske. Boravišna pristojba trebala bi biti sastavni dio cijene smještaja ugostiteljskih objekata. Jedan od glavnih razloga za kalkulaciju boravišne pristojbe u cijenu smještaja je skora primjena Direktive o paket-aranmanima, nakon ulaska Republike Hrvatske u Europsku uniju, gdje se turističke agencije obvezuju sve elemente cijene ukupno sa svim taksama objaviti u jedinstvenoj paušalnoj cijeni paket- aranžmana.Travel agencies are obliged to charge tourist tax for all types of accommodation in the Republic of Croatia. While charging tourist tax, travel agencies get no commission nor have the right to charge handling fee. Tourist taxes are excluded from taxation and they also have to be excluded from the price of the package tour which causes an operational issue for travel agencies, not only appearing when selling package tours from catalogues and brochures, but also when selling online. This way of charging tourist tax causes additional costs for travel agencies, mostly due to large number of additional data imports in reservation systems, but also due to large number of additional accounting transaction appearing through invoice payments. Modifications of the current law relating to tourist taxes are more than required. Tourist tax should form a part of the price for all types of accommodation. One of the reasons why tourist tax should be calculated in the price is the upcoming European Union Directive on Package Holidays which will take effect right after the Republic of Croatia joins the European Union, where all travel agencies are obliged to publish single package price with all price elements and all taxes included

Application of Hygienic Standards and Health Protection in Hotel Wellness Centers in the Republic of Croatia

Wellness se pojavljuje posljednjih godina na svjetskom turističkom tržištu kao jedan od značajnih hotelskih proizvoda. Vrlo oštra konkurencija nameće postizanje i održavanje određene kvalitete hotelskih wellness centara. Kvaliteta i diferenciranost hotelske wellness ponude kao i higijenski standardi hotelskih wellness centara elementi su opstanka i konkurentnosti na svjetskom turističkom tržištu. Značajan broj hotelskih wellness centara u Republici Hrvatskoj ne odgovara svjetskim standardima na koje su zahtjevni inozemni turisti navikli. Cilj ovog rada je ukazati na nužnost izrade pisanih protokola kao obaveznog dijela u provedbi higijenskih standarda u wellness centrima u Republici Hrvatskoj, Hipoteze u ovom radu glase: H1 - većina hotela (više od 50%) ne posjeduje certifikate ISO 9001-2008; H2 - većina hotela (više od 50%) ne posjeduje definirane higijenske standarde u wellness centrima; H3 - većina hotela (više od 50%) ne posjeduje zapis o higijenskom odravanju wellness centara uz potpis odgovorne osobe. Navedeno ima za posljedicu ugrožavanje konkurentnosti hotelskih wellness centara u Republici Hrvatskoj na međunarodnoj razini. Jasna definicija i primjena higijenskih standarda povećava kvalitetu hotelskih wellness centara i utječe na zdravstvenu sigurnost korisnika usluga, a time i na ukupno ostvarene prihode hotela.During the course of the last few years wellness has appeared on tourist markets worldwide as one of the most significant hotel products. Strong competition imposes the achievement and maintenance of certain quality of hotel wellness centers. The existence and competitiveness of hotel wellness centers on global tourist markets depend not only upon their quality and specific distinctive features of their offer but also upon reached hygienic standards. Notable numbers of hotel wellness centers in the Republic of Croatia do not comply with demands of global standards that foreign tourists have been used to. The aim of this work is to point at the need for making and applying hygienic standards in Croatian hotel wellness centers. The hypothesis of this work is as follows: hygienic standards in Croatian hotel wellness centers have not been clearly defined although there are Regulations regarding safety and health protection in hotel wellness centers in the Republic of Croatia. Such a policy consequently endangers competitiveness of Croatian hotel wellness centers on an international level. Clear definition and the application of hygienic standards improve the quality of hotel wellness centers and positively influence safety and health protection of customers thus enhancing competitiveness on an international level and increasing total hotel revenue
