The Casse-tête board puzzle consists of an n×n grid covered with n^2 tokens. m<n^2 tokens are deleted from the grid so that each row and column of the grid contains an even number of remaining tokens. The size of the search space is exponential. This study used a genetic algorithm (GA) to design and implement solutions for the board puzzle. The chromosome representation is a matrix of binary permutations. Variants for two crossover operators and two mutation operators were presented. The study experimented with and compared four possible operator combinations. Additionally, it compared GA and simulated annealing (SA)-based solutions, finding a 100% success rate (SR) for both. However, the GA-based model was more effective in solving larger instances of the puzzle than the SA-based model. The GA-based model was found to be considerably more efficient than the SA-based model when measured by the number of fitness function evaluations (FEs). The Wilcoxon signed-rank test confirms a significant difference among FEs in the two models (p=0.038).

Peredaran narkoba tidak hanya terjadi di berbagai tempat umum, namun juga di dalam suatu lembaga pemasyarakatan. Bagi narapidana yang merupakan mantan pecandu narkoba di lembaga pemasyarakatan, hal ini dapat mempengaruhi potensi mengalami kekambuhan yang menjadi semakin tinggi. Salah satu upaya yang dapat dilakukan untuk menurunkan potensi mengalami kekambuhan adalah dengan pemberian terapi kognitif perilaku. Tujuan dari penelitian ini adalah menguji efektivitas terapi kognitif perilaku untuk menurunkan potensi kekambuhan pada narapidana mantan pecandu narkoba di salah satu lembaga pemasyarakatan di Bali. Penelitian ini menggunakan metode kuantitatif ekperimen dengan one group pretest-posttest design. Teknik sampling yang digunakan adalah pusposive sampling. Data dianalisis menggunakan uji beda Wilcoxon signed-rank test. Hasil penelitian menunjukkan nilai negative ranks = 3 dengan nilai Z= -1.604 dan Asymp. Sig. = 0.109 (p>0.05). Hal ini berarti tidak ada perbedaan yang signifikan potensi kekambuhan narapidana mantan pecandu narkoba di lembaga pemasyarakatan sebelum dan setelah diberikan terapi kognitif perilaku. Meskipun begitu, angka negative ranks menunjukkan bahwa seluruh skor posttest lebih rendah dari skor pretest sehingga dapat disimpulkan bahwa terapi kognitif perilaku dapat menurunkan potensi kekambuhan pada narapidana mantan pecandu narkoba di lembaga pemasyarakatan.  Drug trafficking not only occurs in various public places but also in prison. For the former drug addicts prisoners, this can affect the potential of relapse to become even higher. One effort to reduce the potential of relapse is by giving cognitive behavioral therapy. The purpose of this study was to examine the effectiveness of cognitive- behavioral therapy to reduce the potential of relapse in former drug addicts at one of the prisons in Bali. This study uses quantitative methods with one group pretest-posttest design. The sampling technique used is purposive sampling. Data were analyzed using a Wilcoxon signed-rank test. The results showed the value of negative ranks = 3 with Z values = -1.604 and Asymp. Sig. = 0.109 (p> 0.05). It means there is no significant difference in the potential relapse of the former drug addicts prisoners before and after cognitive-behavioral therapy program. However, negative ranks score indicates that all of the posttest scores are lower than the pretest score. So it can be concluded that cognitive-behavioral therapy can reduce the potential of relapse in former drug addicts prisoners.

A double-blind controlled Ca supplementation trial was conducted for 6 months in thirty-four 7-year-old Chinese children from Hongkong and Jiangmen, China. The children were randomly allocated to the study group (n 17) or control group (n 17), and a CaCO3 tablet (300 mg Ca) or a placebo tablet was taken daily. True fractional Ca absorption (TFCA) was evaluated before and after the trial using stable isotopes: 8 mg44Ca mixed in 100 g chocolate milk was given after an intravenous injection of 0·75 mg 42Ca. There was no significant difference in baseline TFCA between the study group (60·6 (SD 11·4)%) and the controls (58·2 (SD 9.0)% P = 0·55). Serum 25-hydroxycholecalciferol levels were comparable between the two groups (P = 0·71). After 6 months, TFCA of the study group (55·6 (SD 12·7)%) was significantly lower than that of the controls (64·3 (SD 10·7)% P = 0·015). By comparing the individual changes in TFCA after the trial between the two groups there was a non-significant reduction in TFCA (5·03 (SD 12·4)% P = 0·11, Wilcoxon signed-rank test) in the study group (60·6–55·6%), whereas a significant increase in TFCA (6·17(SD 7·7)% P = 0·004, Wilcoxon signed-rank test) was observed in the controls (58·2–64·3%). The differential in TFCA between the two groups after 6 months was significantly different (P = 0·001), and remained significant after adjustment for baseline dietary intakes, weight and height by multiple-regression analysis (P = 0·003). If the mechanism of TFCA from chocolate milk in response to the treatment effects is similar to that from the total diet, then our results suggest that children with adequate vitamin D status can adapt to a change in Ca intake by adjusting the efficiency of TFCA. In corollary, children on habitually-low Ca diets have a higher TFCA than the counterparts with higher Ca diets.

While most studies that explored children’s incidental literacy acquisition focused on input from written text, this quantitative-qualitative study investigated the effects of using audio-visual input through close-captioned Aesop’s Fables cartoons from PinkFong and Task-Induced Involvement (n=6 eight-year old pupils). Wilcoxon Signed Rank Test reveals that there is a significant difference in the pretest, immediate posttest and delayed posttests scores after the intervention as shown in the 90%-95% confidence level. This study also examines quantitatively the interconnectedness of the four areas of children’s literacy skills: vocabulary, oral vocabulary and pronunciation, orthographic skill and comprehension after watching cartoons and engaging in tasks. Findings reveal a high correlation between the four literacy skills reflected as 95% confidence intervals. These findings reveal that incidental literacy acquisition is approached holistictically: the acquisition of one skill leads to the acquisition of the other literacy skills.

SUMMARY Objective: The aim of this study was to evaluate the microleakage of the composite restorations when bonded to tooth structure previously restored with amalgam material compared with that of freshly cut dentin. Methods and Materials: Thirty intact, extracted intact human molars were mounted in autopolymerizing acrylic resin. Class II box preparations were prepared on the occluso-proximal surfaces of each tooth (4-mm bucco-lingual width and 2-mm mesio-distal depth) with the gingival cavosurface margin 1 mm above the CEJ. Each cavity was then restored using high copper amalgam restoration (Disperalloy, Dentsply) and then thermocycled for 10,000 thermal cycles. Twenty-five of the amalgam restorations were then carefully removed and replaced with Filtek Supreme Ultra Universal (3M ESPE); the remaining five were used for scanning electron microscopy and energy dispersive x-ray spectroscopy analysis. A preparation of the same dimensions was performed on the opposite surface of the tooth and restored with composite resin and thermocycled for 5000 thermal cycles. Twenty samples were randomly selected for dye penetration testing using silver nitrate staining to detect the microleakage. The specimens were analyzed with a stereomicroscope at a magnification of 20×. All of the measurements were done in micrometers; two readings were taken for each cavity at the occlusal and proximal margins. Two measurements were taken using a 0-3 scale and the percentage measurements. Results: Corrosion products were not detected in either group (fresh cut dentin and teeth previously restored with amalgam). No statistically significant difference was found between the microleakage of the two groups using a 0-3 scale at the occlusal margins (McNemar test, p=0.727) or proximal margins (Wilcoxon signed-rank test, p=0.174). No significance difference was found between the two groups using the percentage measurements and a Wilcoxon signed-rank test at either the occlusal (p=0.675) or proximal (p=0.513) margins. However, marginal microleakage was statistically significant between the proximal and occlusal margins (p&lt;0.001). Conclusion: Within the limitations of this in vitro study, no significant difference was found between the microleakage of nondiscolored dentin in teeth that were previously restored with amalgam compared with freshly cut dentin. However, marginal microleakage in the proximal surface was higher than that in the occlusal surface.
