Purpose: In order to investigate the incidence of relative afferent pupillary defect (RAPD) in normal adolescence and if there is any interocular difference in the case with RAPD. Methods: Fifty-eight adolescence in 14 to 36 years of age who showed normal findings on measurement of visual acuity, intraocular pressure, slit lamp examination, and funduscopic examination except refractive errors underwent swinging flashlight test and infrared pupillography. The case with RAPD further underwent optical coherence tomography, color vision test, Humphrey visual field test, and Bryngelson test (hole-in-the-card test). Results: One out of 58 cases, in whom more pronounced myopic astigmatism and lower mean deviation on Humphrey visual field test within normal limits were found, showed RAPD in the dominant right eye with swinging flashlight test and infrared pupillography. Conclusions: The incidence of RAPD in normal adolescence was 1.7%. Myopic astigmatism was higher in the eye with RAPD.

Objective The aim of the present study was to compare the efficacy of vaginal isoniazid (isonicotinic acid hydrazide [INH]) and vaginal misoprostol in cervical ripening before hysteroscopic surgery. Methods This randomized controlled trial included patients scheduled for hysteroscopic surgery during April 2016 and June 2017. The inclusion criteria were as follows: postmenopausal women or those at premenopausal age who had not had a vaginal delivery and candidate for diagnostic or operative hysteroscopy with closed cervix before intervention. The INH group (intervention group) received 900 mg of vaginal isoniazid (three 300-mg pills) 6-8 hours before hysteroscopic surgery. The misoprostol group (control group) received 400 micrograms of vaginal misoprostol 6-8 hours before hysteroscopic surgery. Finally, the efficacy of the 2 agents was comparatively analyzed. Results Baseline characteristics were comparable between the groups. In 67 cases in the INH group (95%) and 45 in the misoprostol group (50%), hysteroscopic entry was successful without additional mechanical dilation, and this difference was statistically significant (P=0.001). The odds ratio (OR) obtained in this study was 0.57 for both INH and misoprostol groups (OR, 0.57; 95% confidence interval, 0.43-0.75). Further, 19 cases in the INH group vs. 45 cases in the misoprostol group did not respond to the intervention, indicating statistically significance (P=0.001). Conclusion Vaginal INH is more effective than misoprostol in cervical ripening before hysteroscopic surgery and can be a good alternative to misoprostol.

Purpose : This study compared the differences in power and agility of athletes in each sports using visual response speed test (VRST) scores after conducting 10 weeks of body stability exercise (BSE) on elementary school athletes in handball, football, volleyball and conducted a post-hoc test on the measured values. The subjects of this study were baseball (n=27), taekwondo (n=22), and football (n=23) athletes with at least two years of athletic experience. A total of 72 elementary school athletes were measured by VRST after 10 weeks of BSE under the same conditions. Methods : For VRST measurement of the upper extremity, the right and left hands were alternately touched in the order the blazepod equipment lights were turned on. The number of touches for 15 seconds and response touch were measured. In the case of the measurement of lower extremity the left lower extremity was measured first when the Blaze pod equipment light came on. The average value was obtained by measuring 3 times using a measurement sensor with the position indicated in order to measure the upper arms and legs the same. Results : This study confirmed homogeneity among sports and that VRST improved after implementing BSE for sports. However, no statistically significant difference was identified when comparing VRST improvements between sports, and post-hoc test results showed no significant differences either. Conclusion : After applying the BSE program under the same conditions for 10 weeks to elementary school students who can improve their power and agility the most, the results of the examination using the Blaze pod showed that the power and agility of baseball, taekwondo, and soccer players were similarly improved. From the fact that there was no significant difference among sports, it could be inferred that the BES training program could improve VRST without being limited to some sports.
In search of “Muda” through the TKJ Diagram. An analysis and Classification

Purpose. Muda is a Japanese term literally meaning futility, uselessness, idleness, superfluity, waste, wastage or wastefulness. The term was introduced by the Japanese engineer Taiichi Ohno of Toyota Motor Corporation in the 1960s. Therefore, reducing and minimizing Muda is an effective way to increase the operational efficiency and productivity of an organization’s processes. In turn, the technique known as the affinity or TKJ diagram represents a practical way of sorting data or ideas into groups classified by common patterns; it can be regarded as one of the new seven tools of quality. The purpose of this paper is to discover Muda by applying the affinity or TKJ diagram in Mexican organizations. Design/methodology/approach. An exploratory qualitative study was conducted. Using theoretical sampling, we identified and analyzed data from a kaizen training course. Each course workshop was organized by the consulting firm “Mi Empresa” and given to employees of various organizations in various sectors over three years from January 2012 to January 2015. In total, 36 KJ diagrams were obtained from 12 course workshops. Findings. The research provided the first evidence of Muda in Mexican organizations. The Muda of Ohno’s classification was confirmed, but new common patterns of Muda in 21st century organizations also arose. Furthermore, the TKJ diagram proved to be an effective tool of quality to detect it. Research limitations. This paper has the same limitations as all other qualitative research, including analysis subjectivity and questionable generalization of findings. It is also important to highlight that the 36 KJ diagrams yielded 1,026 Muda, a seemingly abundant figure. However, it is a small sample for the number of companies and processes to be found in Mexico. Practical implications (if possible). This paper may prove to be valuable for practitioners and managers involved in the operations and continuous improvement fields. Getting to know Muda in organizations is of great importance for continuously improving organizational processes. This classification will allow greater insight and easier detection. Originality/value. The study contributes to the limited existing literature on total quality management, lean thinking and kaizen and subsequently disseminates this information in order to provide impetus, guidance and support towards improving the quality of organizational processes.

Tourism portraits complex economic and social character with multidimensional importance in the economic sphere. As a result of the steadily increasing urban pressure (not counting many other complex aspects), the multiplicative nature of tourism it goes in accordance with the needs of the social needs for relaxation and recreation. As it is clear that environment is key factor for Tourism, the approach to it (environment) should be considered from a sensible perspective. Managing and developing tourism also should play an important part within economic development. As from the aspects of heterogeneity (also from the ancestry) values within tourism of Kosovo are made of relatively diversified motives.

Purpose: To investigate the effects of mitomycin C on the scleral collagen surfaces using atomic force microscopy (AFM). Methods: Two non-contact mode AFM machines were used to observe changes in the morphological characteristics of human scleral surfaces before and after one, three, and five minutes of 0.02% mitomycin C application. Based on AFM topography and deflection images of the collagen fibril, the morphological characteristics of scleral fibrils including the fibril diameter and D-period were measured using the line profile. Results: The sclera collagen fibril treated with 0.02% mitomycin C for one minute did not show any significant increases in mean fibril diameter (155.04 ± 17.46 nm) or mean D-periodicity (70.02 ± 3.33 nm), compared to those of the control group. However, the scleral collagen fibrils treated with 0.02% mitomycin C for three and five minutes showed significant increases in mean fibril diameter (182.33 ± 16.33 nm, 199.20 ± 12.40 nm, respectively) and mean D-periodicity (70.27 ± 13.66 nm, 72.75 ± 19.32 nm, respectively), compared to those of the control group. Conclusions: The present study examined the structural changes in the scleral collagen fibrils before and after mitomycin C application according to atomic force microscopy. The results indirectly suggest that three or more minutes of 0.02% mitomycin C application affects the morphology of scleral collagen. J Korean Ophthalmol Soc 2011;52(6):671-678
