Perairan Sungai Wedung merupakan ekosistem pesisir yang banyak dimanfaatkan untuk berbagai kegiatan manusia. Hal tersebut tentunya berpengaruh terhadap kesuburan perairan Sungai Wedung. Kesuburan di perairan tersebut dipengaruhi oleh plankton, faktor kimia, fisika dan juga kandungan Klorofil-A. Pengukuran kandungan klorofil-a fitoplankton merupakan salah satu alat pengukuran kesuburan suatu perairan. Klorofil-a fitoplankton adalah suatu pigmen aktif dalam sel tumbuhan yang mempunyai peran penting dalam berlangsungnya proses fotosintesis perairan. Penelitian dilakukan pada bulan April – Mei 2013 di Sungai Wedung, Demak bertujuan untuk mengetahui aktivitas manusia terhadap sebaran klorofil-a, keterkaitan antara klorofil-a dan kelimpahan fitoplankton dan tingkat kesuburan perairan berdasarkan kandungan klorofil-a fitoplankton. Metode yang digunakan adalah metode studi kasus dengan teknik pengambilan sampel menggunakan metode “Sample Survey Method”. Hasil penelitian menunjukkan bahwa hasil analisis data klorofil menggunakan metode anova tersarang (nested anova) diperoleh nilai P untuk stasiun cukup besar sehingga tidak memberikan perbedaan yang nyata pada taraf kepercayaan 95 %. Akan tetapi perbedaan akan nyata pada taraf 90%. Hubungan antara klorofil-a dengan kelimpahan fitoplankton  secara linear menunjukkan nilai keeratan yang tinggi dengan nilai koefisien korelasi sebesar 0,93 dan koefisien determinasi sebesar 0,8633 dimana 86% klorofil-a dipengaruhi oleh kelimpahan fitoplankton. Berdasarkan nilai rata-rata klorofil-a yang diperoleh sebesar 1,039863 mg/l dapat disimpulkan bahwa perairan Sungai Wedung tergolong kedalam perairan yang bersifat oligotrofik.

Business To Business

The textile industry is production-intensive and incorporates diverse transactions made by multiple suppliers, corporate buyers, and supply chain members. In the business-to-business context, the cost for attracting a new customer is notably much higher than that needed to retain a present one. Customer loyalty in terms of customer repurchase intention has, therefore, been considered as a key determinant for textile companies to improve their efficiency and competitive advantage. This study aims to investigate the business-to-business repurchase intentions of Pakistan textile and clothing industry customers. The study framework specifically consolidates the mutual dynamics of appealing (service quality), facilitating (product returns), and averting (switching costs) factors altogether and the effect of these variables on customer satisfaction and thus on customer retention (repurchase intent) in the textile’s transactional scenario. A sample survey method is used for this study. The data collected through self-administered questionnaires (n = 325) from All Pakistan Textile Mills Association enlisted the employees of the companies. The structural equational modeling technique was applied to examine the study hypotheses. The findings contended that service quality and switching costs are essential determinants that shape the repurchase intentions. Therefore, product returns do not contribute toward customer satisfaction and also do not shape the intentions of business-to-business customers to repurchase from the same supplier after having even a good product return experience in past.

Growth Of Science

With the update and growth of science and technology, educational concepts continue to innovate. In the sports field, the use of Virtual Reality (VR) technology is undoubtedly a brand new training experience. The use of VR technology in the physical education (PE) classroom has promoted the growth of PE and also allowed students to master physical skills more comprehensively through high technology. The purpose of this article is to understand VR technology, study the mterial of VR, improve the shortcomings of traditional PE through VR technology, and analyze the application prospects of VR technology in PE. This article mainly adopts the interview method, sample survey method and case analysis method to sample a survey of 120 students in three grades of a middle school to conduct questionnaire surveys and field visits to understand the students’ knowledge of VR technology and the use of VR technology. We also can know the views of the PE for students. Through this series of investigations, the prospects of VR technology being applied to PE are analyzed. Experimental research results show that the most supported PE activity for VR technology at this stage is situational setting, and 35% of students hope that VR technology will be prominent in the context of the picture. The application of VR technology in physical education will undoubtedly bring a different experience to school sports activities. However, due to the lack of funds and professionals, it is difficult to carry out VR technology in teaching activities. So we can start from the context setting and use economical means to pave the way for physical education.

This paper presents the composition of municipal solid waste in Uyo and vector-borne diseases associated with municipal solid waste within the vicinity of the dumping site (less than 1 km) and controlled site (above 1 km). The compositions of municipal solid waste were determined using samples obtained from Uyo village road waste dumping site. The dumpsite receives solid waste from all the communities in Uyo local government area. In order to assess the public perception of vector-borne diseases associated with municipal solid waste, sample survey method was adopted, which involved the administration of 500 questionnaires of which 250 were administered to the residents who lived less than 1 km from the boundary of the waste dumpsite and 250 questionnaires were also administered to the communities living further away. The compositions and percentages constituent by mass revealed the following: Organic waste component constitute 53.86% and inorganic constituted a waste portion of 46.14%. For vector-borne diseases associated with municipal solid waste, the results indicated that 70.8% of the respondents attended tertiary education (OND/NCE and above), so the issues associated with municipal solid waste may not be strange to them. A significant number of respondents are aware that the origin of municipal solid waste is residential, commercial, industrial, market, street sweeping and industrial sectors. Respondents are more aware that rats, flies, mosquitoes, birds, pigs and cockroaches are vector-borne diseases associated with municipal solid waste. The findings in this study will be useful in a comprehensive solid waste management program which encompasses sweeping, storage, collection and disposal of solid waste. However, the waste can be best treated if any of these techniques are utilized composting, gasification and energy recovery in future for further reduction of waste.

Party Voting

The analysis of voting behavior patterns from electoral statistics aggregated by regions and urban and rural districts has a long and rich tradition (Lipset and Rokkan, 1967). This mode of electoral analysis has, however, declined in usage due to the emergence of the sample survey method, which allows for a more detailed analysis of individual voting choices and the related social and attitudinal factors which influence them.It is often forgotten, however, that aggregate analysis of area or geographically defined voting statistics is a low-cost research method when compared to the exclusive and much more expensive sample survey research method. Aggregate analysis can be applied effectively with careful adaptation to most of the areas of electoral analysis, particularly so in societies in which community and residential patterns are structured according to clear socioeconomic and stratification variables such as income, status, and occupation. This applies as well to societies in which regional and cerritorial divisions are more than just administrative units but represent focal points of local identities and loyalties.
