AbstrakPenelitian ini menggambarkan tentang berbagai latar belakang pengambilan keputusan Putin atas isu Krimea yang melihat dasar-dasar pengambilan keputusan seperti intuisi, pengalaman, fakta, wewenang, dan rasionalitas yang memengaruhi Putin dalam melakukan aksi aneksasi Krimea tersebut. Dalam penulisan skripsi ini, sang penulis menggunakan kerangka teori Pengambilan Keputusan (Decision Making) yang merupakan topik utama sekaligus pisau analisa dalam penelitian ini. Metode penelitian yang digunakan oleh sang penulis dalam penyusunan skripsi ini adalah metode kualitatif. Adapun teknik pengumpulan data yang digunakan oleh sang penulis dalam memperoleh data adalah melalui wawancara dan studi pustaka yang menelaah sejumlah buku, jurnal, artikel ilmiah, dan media elektronik. Hasil penelitian menunjukkan bahwa latar belakang pengambilan keputusan Vladimir Putin adalah berdasarkan pilihan rasional dengan melihat pertimbangan materil seperti memberi keuntungan di sektor keamanan, ekonomi, politik, memberikan peluang Rusia menjadi negara adidaya, dan pengamanan jalur pipa gas Rusia di Ukraina dan Krimea. Yang menarik dari tindakan yang diinisiasi oleh Putin itu adalah aksi tersebut dalam merebut suatu wilayah tanpa pencurahan darah. Ini adalah hal yang menarik bagi sang penulis karena bagaimana mungkin suatu intervensi militer di suatu wilayah tidak terjadi penyerangan dari pihak luar ke dalam suatu wilayah, dalam hal ini adalah aksi Rusia kepada Krimea. Politik keamanan, politik identitas, dan politik ekonomi mewarnai Putin dalam pengambilan keputusannya atas isu Krimea tersebut.Kata Kunci: Vladimir Putin, Pengambilan Keputusan, Pilihan                          Rasional, Rusia, Krimea, Ukraina.Abstract This research describes the various backgrounds of Putin's decision making on the Crimean issue which looks at the basics of decision making such as intuition, experience, facts, authority and rationality that influenced Putin in carrying out the Crimean annexation. In writing this thesis, the writer uses the theoretical framework of Decision Making which is the main topic as well as the analysis knife in this research. The research method used by the author in the preparation of this thesis is a qualitative method. The data collection techniques used by the author in obtaining data are through interviews and literature studies that examine a number of books, journals, scientific articles, and electronic media. The results show that the background of Vladimir Putin's decision making is based on rational choices by looking at material considerations such as providing benefits in the security, economic, political sectors, giving Russia the opportunity to become a superpower, and securing Russian gas pipelines in Ukraine and Crimea. What's interesting about the action initiated by Putin is that it seizes an area without shedding blood. This is an interesting matter for the author because how could a military intervention in a region not occur from outside attacks into an area, in this case Russia's action against Crimea. Security politics, identity politics and economic politics colored Putin in his decision making on the Crimean issue. Keywords:  Vladimir Putin, Decision Making, Rational Choice,                          Rusia, Crimea, Ukraine.

This study investigated certified teachers’ performance at SMPN 6 Luwuk of Banggai Regency, with a focus on the teachers’ performance in planning the lesson, implementing the lesson, and conducting the lesson evaluation. It lasted for nine months, from March to December 2011. Qualitative method was used. More specifically, the evaluation research method was followed which involves collecting, analyzing, and interpreting data for decision making. The evaluation system used in this study was based on the quality of the certified teachers’ performances. The real condition in the field is that many of the certified teachers are still unable to design lessons and implement them professionally as expected from certified teachers. Currently there are many teachers in need of trainings. This study showed that the quality of the performance of the certified teachers in SMPN 6 Luwuk in planning the lesson was low. This could indicate that the certification process has not yet resulted in an increase in the quality of performance of the certified teachers, particularly as long as the quality of their performance in planning lessons is concerned.

Decision-making for the hospitalized dying and critically ill is often characterized by an understanding of autonomy that leads to clinical care and outcomes that are antithetical to patients’ preferences around suffering and quality of life. A better understanding of autonomy will facilitate the ultimate goal of a patient-centered approach and ensure compassionate, high-quality care that respects our patients’ values. We reviewed the medical literature and our experiences through the ethics service, palliative care service, and critical care service of a large community teaching hospital. The cumulative experience of a senior intensivist was filtered through the lens of a medical ethicist and the palliative care team. The practical application of patient-centered care was discerned from these interactions. We determined that a clearer understanding of patient-centeredness would improve the experience and outcomes of care for our patients as well as our adherence to ethical practice. The practical applications of autonomy and patient-centered care were evaluated by the authors through clinical interactions on the wards to ascertain problems in understanding their meaning. Clarification of autonomy and patient-centeredness is provided using specific examples to enhance understanding and application of these principles in patient-centered care.

Natural, standard, and compound curing are adopted to study the effect of different curing systems on the reinforcement of carbon fiber in reactive powder concrete (RPC). This work systematically studies the changes in RPC compressive and tensile strengths under different curing systems. Taking age, fiber content, and curing system as parameters, Scanning electron microscope (SEM) and X-ray diffraction (XRD) microscopic methods are used to study the influencing mechanism of carbon-fiber content and curing systems on RPC. The calculation methods of the RPC strength of different carbon-fiber contents are studied. Results show that the optimum carbon-fiber content of carbon-fiber RPC is 0.75% under the natural, standard, and compound curing conditions. In comparison with standard curing, compound curing can improve the early strength of carbon-fiber RPC and slightly affect the improvement of late strength. The strength is slightly lower in natural curing than in standard curing, but the former basically meets the requirements of the project and is beneficial for the practical application of this project. The calculation formula of 28-day compressive and splitting tensile strengths of carbon-fiber content from 0% to 0.75% is proposed to select the carbon-fiber content flexibly to satisfy different engineering requirements.

It is presented a software developed with Delphi programming language to compute the reservoir's annual regulated active storage, based on the sequent-peak algorithm. Mathematical models used for that purpose generally require extended hydrological series. Usually, the analysis of those series is performed with spreadsheets or graphical representations. Based on that, it was developed a software for calculation of reservoir active capacity. An example calculation is shown by 30-years (from 1977 to 2009) monthly mean flow historical data, from Corrente River, located at São Francisco River Basin, Brazil. As an additional tool, an interface was developed to manage water resources, helping to manipulate data and to point out information that it would be of interest to the user. Moreover, with that interface irrigation districts where water consumption is higher can be analyzed as a function of specific seasonal water demands situations. From a practical application, it is possible to conclude that the program provides the calculation originally proposed. It was designed to keep information organized and retrievable at any time, and to show simulation on seasonal water demands throughout the year, contributing with the elements of study concerning reservoir projects. This program, with its functionality, is an important tool for decision making in the water resources management.
