Objective: Irregular patterns of marital cohabitation are a common problem in upper Egypt due to employment conditions. The objective of this study was to investigate the effect of irregular marital cohabitation on the quality of life and sexual function of infertile men. Methods: In total, 208 infertile men were included and divided into two groups. The first group included 134 infertile men with an irregular pattern of marital cohabitation and the second group included 74 infertile men with a regular pattern of marital cohabitation. All subjects were assessed through a clinical evaluation, conventional semen analysis, the fertility quality of life (FertiQoL) questionnaire, the International Index of Erectile Function (IIEF-5) score, and the premature ejaculation diagnostic tool (PMEDT). Results: The two groups were compared in terms of conventional semen parameters, FertiQoL, IIEF-5 score, and PMEDT. Infertile men with an irregular pattern of marital cohabitation had significantly lower subscale and total FertiQoL and IIEF-5 scores. Additionally, they had significantly higher PMEDT scores. Erectile dysfunction and premature ejaculation were more common in them than in infertile men with a regular pattern of marital cohabitation. Conclusion: Irregular patterns of marital cohabitation had an adverse effect on quality of life and sexual function in infertile men.

The purpose of this study was to research the characteristics of the pattern design and the weave construction of 67 fashion fabrics in women's Hanbok. All the fabrics were made by 100% silk. Arrangement, size, and the type of patterns were investigated for research of the pattern characteristics. Pattern weave and background weave were analyzed, then the weight and the thickness were measured for studying the fabric construction. The results were as follows. First, irregular arrangement was more commonly used than regular arrangement, and then the complex arrangement and the combination arrangement were appeared considerably because of the existence of the various patterns in a fabric. Third, the types of pattern weave construction were much more than those of background weave construction. This is caused by the expression of dimensional effect for patterns. This survey can be practically used for development of pattern design for Hanbok industry and furthermore it will contribute to revitalizing of Hanbok market to overcome design limit in the future.

Predicting locations of users with portable devices such as IP phones, smart-phones, iPads and iPods in public wireless local area networks (WLANs) plays a crucial role in location management and network resource allocation. Many techniques in machine learning and data mining, such as sequential pattern mining and clustering, have been widely used. However, these approaches have two deficiencies. First, because they are based on profiles of individual mobility behaviors, a sequential pattern technique may fail to predict new users or users with movement on novel paths. Second, using similar mobility behaviors in a cluster for predicting the movement of users may cause significant degradation in accuracy owing to indistinguishable regular movement and random movement. In this paper, we propose a novel fusion technique that utilizes mobility rules discovered from multiple similar users by combining clustering and sequential pattern mining. The proposed technique with two algorithms, named the clustering-based-sequential-pattern-mining (CSPM) and sequential-pattern-mining-based-clustering (SPMC), can deal with the lack of information in a personal profile and avoid some noise due to random movements by users. Experimental results show that our approach outperforms existing approaches in terms of efficiency and prediction accuracy.

The ball-end milling process is widely used in the die/mold industries, and it is very suitable for the machining of free-form surfaces. However, this process is inherently inefficient process to compared with the end-milling or face milling process, since it relays upon the machining at the cutter/surface contact point. The machined part is the result of continuous point-to-point machining on the free-form surface. And cusps (or scallops) remain at the machined part along the cutter paths and they give the geometrical roughness of the workpiece. Thus, for the good geometrical roughness of the workpiece, it is required very tightly spaced cutter paths in this ball-endmilling process. However, with the tight cutter paths, the geometrical roughness of the workpiece is not regular on the workpiece since the cusp height is variable in the previously developed ISO-parametric or Cartesian machining methods. This paper suggests a method of tool path generation which makes the geometrical roughness of workpiece be constant through the machined surface. In this method, Ferguson Surface design Model is used and cusp height is derived from the instantaneous curvatures. And, to have constant cusp height, an increment of parameter u or v is estimated along the reference cutter path. In ball-end milling experiments, the cusp pattern was examined, and it was proved that the geometrical roughness could be regular by suggested tool path generation method.

This study suggested criterion for Petite-size and analyzed the body size and characteristics that were proper to manufacture clothing for Korean Petite-size women aged 18 to 34. It also analyzed size information about pattern making for Petite-size women through a comparison of the size and proportion of Petite-size with Regular-size. The criterion of Petite-size was decided in consideration of the distribution and perception of stature; subsequently, the stature range for Petite-size was defined as under 157.5cm. Body size and proportion of Petite-size were analyzed through calculating the mean from 25 to 75 percentiles of a Petite-size stature range. The Petite-size of this study was compared to KS Petite and total subjects through One way ANOVA. It was confirmed that the Petite-size of this study had body characteristics like KS Petite; however, Petite-size was larger in height and vertical length than KS Petite. The significant differences between Petite-size and Regular-size were identified in the same bust girth range, that required a revised calculation formula for pattern making that would be proper for Petite-size. It is expected that the Body size and proportion could be utilized as a reference for manufacturing or purchasing Petite-size clothing. The result of this study will contribute to enhance the fit satisfaction for Petite-size women aged 18 to 34.

Seven new species of two genera Scalarispongia and Smenospongia (Demospongiae: Dictyoceratida: Thorectidae) are described from Gageo Island and Jeju Island, Korea. Five new species of Scalarispongia are compared to nine reported species of the genus by the skeletal structure. Scalarispongia viridis n. sp. has regular ladder-like skeletal pattern arranged throughout the sponge body and has pseudo-tertiary fibres. Scalarispongia favus n. sp. is characterized by the honeycomb shape of the surface and is similar to Sc. flava in skeletal structure, but differs in sponge shape. Scalarispongia lenis n. sp. is similar to Sc. regularis in skeletal structure but has fibers that are smaller in size. Scalarispongia canus n. sp. has irregular skeletal structure in three dimensions and ladder-like which comes out of the surface and choanosome. Scalarispongia subjiensis n. sp. has pseudo-tertiary fibres and its regular ladder-like skeletal pattern occurs at the choanosome. Two new species of Smenospongia are distinguished from the other 19 reported species of the genus by the skeletal structure. Smenospongia aspera n. sp. is similar to Sm. coreana in sponge shape but new species has rarely secondary web and thin and thick bridged fibres at near surface. Smenospongia mureungensis n. sp. has very simple skeletal structure.

The Regular rule of Sang-uiwon served as a manual of Royal Attires. According to the procedures, like as making letters about the affairs, consulting, and permission, Royal ceremonial attire was made and presented to the royal family. The materials for the Royal informal dress were presented in accordance with usual tributes. There was no difference in informal dress between the royal family and noble class. But the name of items was different such as Goa du[man's jacket], Go ui[woman's jacket], etc. The royal family continued to wear old days dress as akjurm and noui, which were not worn by common people any more, as a means of differentiating clothes. Bub-bok, which was designed only for key figures of the royal family such as the king, crown prince, queen, and crown princess, was the best status symbol. Because of its highly limited example of wearing, bub-bok was the authority of the wearer itself; with only difference in color, pattern, and material depending on social status. Yong-po is the most frequently worn by the Royal men. Yong-po worn with jong-lip served as yung-bok or gun-bok, and iksun-gwan functioned as sang-bok. Royal Attire for men was clearly divided into Yong-po as sang-bok, bub-bok as myun-bok and gangsa-po, while jeok-ui for women functioned as both sang-bok and bub-bok. However, the use of jeok-ui was defined by differentiate sang-bok from bub-bok like as the pattern of Hyung-bae, number of embroidered round badges, shoes and ornaments.

Regular dental visit of disabled patients is an important strategy for maintenance of oral health because of the lack of awareness of oral care. But there is limited information about follow up period in disabled patients after dental treatment. The aim of this study was to investigate the pattern of dental visit and dental management of special care needs patients according to the types of disabilities. A total of 140 patients who received dental treatment at Seoul National University Dental Hospital from 2010 to 2012 were reviewed. Patients were divided 3 groups according to the types of disabilities (disorder of external physical function, disorder of internal organ, psychic disability). Patient's characteristic, dental treatment performed, follow up period and frequency were investigated. The mean follow up period was 28.2 months and average frequency of visit was 3.69 times per year. There was no difference in period and annual visit between 3 groups, but significantly difference in cooperation with medical hospital in affiliation. Regular check-up was the most common dental treatment in all groups. In psychic disorder group, the proportion of sedative treatment was significantly higher than other groups. The results of this study provide information necessary for treatment planning and dental management of disabled patients.
