Astronomically, Easter falls on the first Sunday following the first full moon after the vernal equinox. In Indonesia, Christian holidays including Easter are regulated by the Ministry of Religious Affairs based on the recommendation of Indonesian Church Union (PGI) and Bishops Conference of Indonesia (KWI). This study objective is to formulate a simple time marker by using Meeus Astronomical Algorithm to determine Christian holidays in Indonesian Gregorian calendar. Another objective is to evaluate the Christian holidays on Indonesian calendar between 1960 and 2015. Finally, this study would also provide prediction for future Christian holidays. This study finds out that the Christian holidays on Indonesian calendar are proven as methodologically accurate. It indicates that Meeus Astronomical Algorithm can produce accurate calculation for determining Christian holidays in Indonesia in the future. KEY WORDS:Meeus astronomical algorithm, christian holidays, Indonesian calendar

A symposium on the future of the International Latitude Service (I. L. S.) is to be held in Helsinki in July 1960. My report for the symposium consists of two parts. Part I, denoded (Mk I) was published [1] earlier in 1960 under the title “Latitude and Longitude, and the Secular Motion of the Pole”. Part II is the present paper, denoded (Mk II).

<p><strong>A</strong><strong>bstract</strong><strong>.</strong> DKI Jakarta Province plays a crucial role as the center of government and economy in Indonesia. The description of currency inflows and outflows is highly required before Bank Indonesia formulates the appropriate policies to control the circulation of money. The monthly data of currency inflow and outflow of Bank Indonesia of DKI Jakarta show a significant increase in each year particularly before, during, and after Eid al-Fitr. The determination of Eid al-Fitr does not follow the Gregorian calendar but based on the Islamic calendar. The difference in the use of the Gregorian and Islamic calendars in a time series causes a calendar variation. Thus, the determination of Eid al-Fitr in the Gregorian calendar changes as it goes forward eleven days each year or one month every three years. This study aims to obtain the best model and forecast currency inflows and outflows of Bank Indonesia DKI Jakarta using the ARIMAX and SARIMAX models. The study used in-sample data from January 2009 to December 2018 and out-sample data from January to October 2019. The best model was selected based on the smallest out-sample MAPE value. The result showed that the best forecasting model of inflow was ARIMAX (1,0,1). Meanwhile, the best forecasting model for outflow was SARIMAX (2,0,1)(0,0,1)<sup>12</sup>.</p><p><strong>Keywords: </strong>ARIMAX, calendar variation, forecasting, SARIMAX</p>

Role Of The Government

Throughout 2018, relations between Turkey and the United States seemed to deteriorate. The leaders of the two countries issued sharp diplomatic statements and the US even imposed economic sanctions on Turkey. This article aims to analyze how the future of relations between Turkey and the United States. Cooperation between the two has a long historical side after the Cold War. Relations between the two countries are based on various interests, both economic, political, military and security interests. The theory used in this study is the theory of national interest. The US has great interests in the Middle East and Turkey is the front-line ally in achieving those interests. However, there are many US foreign policies that ignore the Turkish concern and create tensions between the two countries. On the contrary, Turkey also has considerable economic interests, but the role of the government elite (in this case, President Erdogan) has a significant influence in the determination of Turkish foreign policy. The findings of this study, although it will go through complex challenges and processes, the US and Turkey will continue to maintain their relations.

Several exciting lines of research have emerged from the study of animal models of mental disorders. This chapter presents seven opportunities for enhancing the diagnosis and treatment of mental disorders. They include improvements to the system for diagnosis of mental disorders, use of induced pluripotent stem cells from patients to generate neuronal cultures for in vitro determination of effective drug therapies for those individuals, use of data-mining techniques for understanding patient variability, a commitment to a greater focus on the prevention of mental disorders, innovative uses of smartphones to track patients and individuals at high risk of developing a mental disorder, and developing next-generation therapies and delivery systems that target a specific area of the brain rather than the entire brain. A common theme in these seven thoughts for the future is a commitment to bringing precision medicine tools to the treatment of patients with mental disorders.

We have used rocket-borne photometers to determine the ultra-violet flux of the full moon in the wavelength range 2400-2900A where atmospheric ozone prevents ground-based observations. The lunar fluxes determined in two rocket firings from Woomera on 9th December, 1965, and 30th August, 1966, are summarized in the Table. The results for the two firings have been corrected to full moon values on the assumption that the lunar phase law is the same at these ultra-violet wavelengths as it is in the visible.

AbstractA new extraction system has been constructed and tested which allows the extraction of gases from air bubbles in ice without melting it. An ice sample of up to 20 g is crushed in a sealed container by a milling cutter and the gas escaping from the opened bubbles is flushed with helium to a Porapak column where it is stored until its injection into the gas Chromatograph. To avoid any contamination with CH4produced by friction in the gear section, a helium-flushed rotary feed-through is used. CH4analyses on ice samples of about 10 g from the last 1000 years give precise and reproducible results. In the future, it is planned to measure also the CO2and N2O concentrations on the same sample.

In order to investigate the diatom distribution in the five lakes along the Yangtze River, and discuss the significance for the diagnosis of drowning. 6 water samples were collected in the five lakes along Yangtze River in June, 2012. Subsequently, The genus and the quantity of the diatoms in the water samples were investigated using scanning electron microscopy (SEM). The result showed us that there was significant difference between the waters sampled from the different sites . These data on diatom distribution are helpful to the diagnosis of the cause of the death as well as to the determination of the drowning site in cases of drowning. Therefore, it is necessary to develop the database of diatoms in more extensive water bodies for the forensic diagnosis of drowning in the future.

Three hundred and twenty-six patients with diagnoses of serous otitis media—or mucold otitis medid—were reviewed for the presence or absence of middle ear cilia activity. This study strongly suggests that if active cilia can be observed, ventilating tubes are not needed. This easily observed activity in the anterior-inferior quadrant offers the otolaryngologist an accurate tool for determination of the future health of the middle ear.
