Pangan penting bagi hidup dan penghidupan manusia. Manusia harus makan dalam ukuran dan komposisi yang tepat. Berbagagai usaha telah dilakukan manusia untuk menjamin ketersediaan bahan pangan. Kenaikan luas panen dan produktivitas selalu diupayakan. Deversifikasi tanaman pangan dan komposisi konsumsi menjadi perhatian pemerintah maupun para ahli pertanian dan gizi. Keterbatasan lahan tanam oleh adanya alih fungsi lahan menjadi hal yang serius sekarang ini. Pertambahan penduduk memerlukan terpenuhi kebutuhan tempat hunian dan fasilitas publik yang lain. Adanya perubahan iklim mengganggu ketersediaan air untuk pertanian dan kebutuhan sehari-hari. Sementara itu penduduk masih tetap mengalami pertambahan dan pertumbuhan. Di beberapa negara maju pertambahan penduduk sudah mencapai tingkatan yang rendah, yaitu kurang dari satu persen tiap tahun. Keadaan di negara yang sedang berkembang sebagian besar masih pada posisi sedang sampai tinggi. Kata Kunci: Penduduk, Ketahanan, Pangan
PARIWISATA DAN PELESTARIAN SENI TRADISI MENYONGSONG YOGYAKARTA PUSAT BUDAYA 2020

Published: July 2018

Yogyakarta merupakan kota yang mempunyai sejarah panjang terkait dengan keberadaan Kraton Ngayogyakarta Hadiningrat. Di kota ini terdapat banyak peninggalan sejarah dan budaya, baik berupa bangunan bersejarah maupun seni tradisi yang adiluhung. Namun seni tradisi khususnya tari keberadaannya kini semakin terdesak oleh sarana hiburan modern. Penelitian ini bertujuan untuk mengkaji kebijakan pemerintah daerah dalam pelestarian dan pengembangan seni tradisi, mengkaji strategi pemerintah dalam pengembangan pariwisata serta kerjasama kelompok tradisi dengan pengelola pariwisata. Pada penelitian ini akan ditempuh cara penelitian dengan menerapkan prinsip-prinsip metode etnografi, untuk melihat seni tradisi atraksi wisata, dan latar belakang pelakunya. Di samping juga dilakukan studi dokumen untuk melihat kebijakan pemerintah dalam bidang pariwisata, khususnya yang berkaitan dengan atraksi wisata. Hasil penelitian menunjukan bahwa seni tradisi boleh dikata mulai jauh dari masyarakat pendukungnya, sehingga jika tidak ada keberpihakan dari pemertintah terhadap seni tradisi maka dalam satu atau generasi ke depan seni tradisi akan menjadi kebudayaan mati. Berbagai strategi yang ditempuh pemerintah antara lain melalui festival seni, pembukaan sekolah seni baik di tingkat menengah maupun perguruan tinggi, serta peningkatan industri pariwisata. Pelestarian seni tradisi khususnya tari justru muncul dari dunia pariwisata, yang memanfaatkan seni tradisi sebagai sajian wisata. Sayang penghargaan dunia pariwisata terhadap seniman tradisi sebagai pekerja seni masih jauh dari memadai, sehingga terkesan seni tradisi hanya dimanfaatkan dunia pariwisata.

The Effect of Mandatory Quarterly Reporting on Firm Value
Authors: Kajüter Peter , Klassmann Florian , Nienhaus Martin 
Published: July 2018

ABSTRACT
We exploit a regulatory change in Singapore to analyze the capital market effects of mandatory quarterly reporting. The listing rule implemented in 2003 has required firms with a market capitalization above S$75 million—but not firms with a market capitalization below this threshold—to publish quarterly financial statements. Using regression discontinuity analysis for our identification, we provide novel evidence of the causal effects of mandatory quarterly reporting on small firms. We find a 5 percent decrease in firm value, consistent with the notion that mandatory quarterly reporting is perceived as a net burden for small firms. Contrary to popular belief, we cannot find evidence of informational benefits or myopic investment for firms around the threshold. Additional tests suggest positive information spillover effects from large mandatory quarterly reporters to non-quarterly reporting firms.

Published: July 2018

This study aimed to reveal the effectiveness of a training program based on a creative problem solving model (CPS) in developing mathematical power for 8th grade students in light of their mathematics achievement. To achieve this goal, a training program was designed to focus on a set of mathematical ideas and skills in an algebra quantities unit using creative problem solving strategies. The researcher designed a test to measure mathematics power. The sample of the study consisted of 135 female eight grade students randomly selected from Dhahra governorate, which was divided into experimental and control groups. For testing the study hypothesis, data were analyzed by analysis of covariance (ANCOVA 2X3) in which eta squared was obtained. The study revealed a significant difference (α=0.05) in the means between the experimental and control groups in the mathematical power test in favor of the experimental group.

Abstract
OBJECTIVE To evaluate the thermal antinociceptive effects and pharmacokinetics of hydromorphone hydrochloride after IM administration to cockatiels (Nymphicus hollandicus).
ANIMALS 16 healthy adult cockatiels.
PROCEDURES During the first of 2 study phases, each cockatiel received each of 4 treatments (hydromorphone at doses of 0.1, 0.3, and 0.6 mg/kg and saline [0.9% NaCl] solution [0.33 mL/kg; control], IM), with a 14-day interval between treatments. For each bird, foot withdrawal to a thermal stimulus was determined following assignment of an agitation-sedation score at predetermined times before and for 6 hours after each treatment. During the second phase, a subset of 12 birds received hydromorphone (0.6 mg/kg, IM), and blood samples were collected at predetermined times for 9 hours after drug administration. Plasma hydromorphone concentration was determined by liquid chromatography–mass spectrometry. Noncompartmental analysis of sparse data was used to calculate pharmacokinetic parameters.
RESULTS Thermal withdrawal response did not differ among the 4 treatment groups at any time. Agitation-sedation scores following administration of the 0.3-and 0.6-mg/kg doses of hydromorphone differed significantly from those treated with saline solution and suggested the drug had a sedative effect. Plasma hydromorphone concentrations were > 1 ng/mL for 3 to 6 hours after drug administration in all birds.
CONCLUSIONS AND CLINICAL RELEVANCE Results indicated that IM administration of hydromorphone at the evaluated doses did not increase the thermal withdrawal threshold of cockatiels despite plasma drug concentrations considered therapeutic for other species. Further research is necessary to evaluate the analgesic effects of hydromorphone in cockatiels.

Published: July 2018

Abstract
OBJECTIVE To quantify fatigue-induced electromyographic changes in hind limb muscles in horses.
ANIMALS 8 Thoroughbreds.
PROCEDURES The left and right hind limb longissimus dorsi, tensor fasciae latae, gluteus medius, and biceps femoris muscles were instrumented for surface electromyography. Hoof strain gauges were attached to confirm stride cycle. Each horse was galloped on a treadmill (grade, 3%) at a constant speed (12.6 to 14.7 m/s) to achieve fatigue after approximately 360 seconds. Before and after this exercise, the horses were trotted at 3.5 m/s. At 30-second intervals during galloping an integrated electromyography (iEMG) value for a stride and the median frequency of muscle discharge (MF) in each limb were measured. The mean of stride frequency (SF), iEMG value, and MF of 5 consecutive strides at the start and end of galloping for the lead and trailing limbs were compared. For trotting, these variables were compared at 60 seconds before and after galloping.
RESULTS The mean ± SD value for SF decreased over time (2.14 ± 0.06 to 2.05 ± 0.07 stride/s). In both the lead and trailing limbs, fatigue decreased the iEMG values of the gluteus medius and biceps femoris muscles but not those of the longissimus dorsi and tensor fasciae latae muscles. The MF did not change for any muscle during galloping with fatigue. The SF, iEMG value, and MF did not change during trotting with fatigue.
CONCLUSIONS AND CLINICAL RELEVANCE Fatigue induced by high-speed galloping decreased the gluteus medius and biceps femoris muscles' iEMG values in Thoroughbreds. Fatigue of these less fatigue-resistant hind limb muscles would affect a horse's speed.
Use of crown height of the maxillary first molar tooth to approximate the age of horses
Authors: Carmalt James L. , Henderson Kirsten V. , Rawlinson Jennifer E. , Waldner Cheryl L. 
Published: July 2018

Abstract
OBJECTIVE To identify whether age, sex, or breed is associated with crown height of the left and right maxillary first molar tooth (M1) measured on CT images, to develop a mathematical model to determine age of horses by use of M1 crown height, and to determine the correlation between M1 crown height measured on radiographic and CT images.
SAMPLE CT (n = 735) and radiographic images (35) of the heads of horses.
PROCEDURES Crown height of left and right M1 was digitally measured on axial CT views. Height was measured on a lateral radiographic image when available. Linear regression analysis was used to identify factors associated with crown height. Half the data set was subsequently used to generate a regression model to predict age on the basis of M1 crown height, and the other half was used to validate accuracy of the predictions.
RESULTS M1 crown height decreased with increasing age, but the rate of decrease slowed with increasing age. Height also differed by sex and breed. The model most accurately reflected age of horses < 10 years old, although age was overestimated by a mean of 0.1 years. The correlation between radiographic and CT crown height of M1 was 0.91; the mean for radiographic measurements was 2.5 mm greater than for CT measurements.
CONCLUSIONS AND CLINICAL RELEVANCE M1 crown height can be used to predict age of horses. Results for CT images correlated well with those for radiographic images. Studies are needed to develop a comparable model with results for radiographic images.

Published: July 2018

Abstract
OBJECTIVE To quantify the effect of time and recumbency on CT measurements of lung volume and attenuation in healthy cats under general anesthesia.
ANIMALS 8 healthy research cats.
PROCEDURES Anesthetized cats were positioned in sternal recumbency for 20 minutes and then in left, right, and left lateral recumbency (40 minutes/position). Expiratory helical CT scan of the thorax was performed at 0 and 20 minutes in sternal recumbency and at 0, 5, 10, 20, 30, and 40 minutes in each lateral recumbent position. For each lung, CT measurements of lung volume and attenuation and the extent of lung areas that were hyperaerated (−1,000 to −901 Hounsfield units [HU]), normoaerated (−900 to −501 HU), poorly aerated (−500 to −101 HU), or nonaerated (−100 to +100 HU [indicative of atelectasis]) were determined with a semiautomatic threshold-based technique. A restricted maximum likelihood analysis was performed.
RESULTS In lateral recumbency, the dependent lung had significantly greater attenuation and a lower volume than the nondependent lung. Within the dependent lung, there was a significantly higher percentage of poorly aerated lung tissue, compared with that in the nondependent lung. These changes were detected immediately after positioning the cats in lateral recumbency and remained static with no further significant time-related change.
CONCLUSIONS AND CLINICAL RELEVANCE Results indicated that once anesthetized healthy cats were positioned in lateral recumbency, the dependent lung lobes underwent a rapid reduction in lung volume and increase in lung attenuation that did not progress over time, predominantly attributable to an increase in poorly aerated lung tissue.

Published: July 2018

Abstract
OBJECTIVE To measure effects of oral Akkermansia muciniphila administration on systemic markers of gastrointestinal permeability and epithelial damage following antimicrobial administration in dogs.
ANIMALS 8 healthy adult dogs.
PROCEDURES Dogs were randomly assigned to receive either A muciniphila (109 cells/kg; n = 4) or vehicle (PBS solution; 4) for 6 days following metronidazole administration (12.5 mg/kg, PO, q 12 h for 7 d). After a 20-day washout period, the same dogs received the alternate treatment. After another washout period, experiments were repeated with amoxicillin-clavulanate (13.5 mg/kg, PO, q 12 h) instead of metronidazole. Fecal consistency was scored, a quantitative real-time PCR assay for A muciniphila in feces was performed, and plasma concentrations of cytokeratin-18, lipopolysaccharide, and glucagon-like peptides were measured by ELISA before (T0) and after (T1) antimicrobial administration and after administration of A muciniphila or vehicle (T2).
RESULTS A muciniphila was detected in feces in 7 of 8 dogs after A muciniphila treatment at T2 (3/4 experiments) but not at T0 or T1. After metronidazole administration, mean change in plasma cytokeratin-18 concentration from T1 to T2 was significantly lower with vehicle than with A muciniphila treatment (−0.27 vs 2.4 ng/mL). Mean cytokeratin-18 concentration was lower at T1 than at T0 with amoxicillin-clavulanate. No other significant biomarker concentration changes were detected. Probiotic administration was not associated with changes in fecal scores. No adverse effects were attributed to A muciniphila treatment.
CONCLUSIONS AND CLINICAL RELEVANCE Detection of A muciniphila in feces suggested successful gastrointestinal transit following oral supplementation in dogs. Plasma cytokeratin-18 alterations suggested an effect on gastrointestinal epithelium. Further study is needed to investigate effects in dogs with naturally occurring gastrointestinal disease.
