Objectives: Regression, while not a core symptom of autism spectrum disorder (ASD), has been suggested to be a distinct subtype by previous studies. Therefore, this study aimed to explore the prevalence and clinical differences between those with and without regression in children with ASD. Methods: This study includes data from toddlers and young children aged 2-7 years acquired from other projects at Seoul National University Bundang Hospital. The presence and characteristics of regression were explored using question items #11-28 from the Autism Diagnostic Interview-Revised. Chi-square and independent t-tests were used to compare various clinical measurements such as autistic symptoms, adaptative behavior, intelligence, and perinatal factors. Results: Data from 1438 young children (1020 with ASD) were analyzed. The overall prevalence rate of regression, which was mainly related to language-related skills, was 10.2% in the ASD group, with an onset age of 24 months. Regarding clinical characteristics, patients with ASD and regression experienced ASD symptoms, especially restricted and repetitive interests and behaviors, with greater severity than those without regression. Furthermore, there were significant associations between regression and hypertension/placenta previa. Conclusion: In-depth surveillance and proactive interventions targeted at young children with ASD and regression should focus on autistic symptoms and other areas of functioning.

The main focus of this study was the evaluation of arsenic concentration in the ground water of Lahore at different depth and application of different mitigation techniques for arsenic removal. Twenty four hours of solar oxidation gives 90% of arsenic removal as compared to 8 hr. or 16 hr. Among oxides, calcium oxide gives 96% of As removal as compared to 93% by lanthanum oxide. Arsenic removal efficiency was up to 97% by ferric chloride, whereas 95% by alum. Activated alumina showed 99% removal as compared to 97% and 95% removal with bauxite and charcoal, respectively. Elemental analysis of adsorbents showed that the presence of phosphate and silica can cause a reduction of arsenic removal efficiency by activated alumina, bauxite and charcoal. This study has laid a foundation for further research on arsenic in the city of Lahore and has also provided suitable techniques for arsenic removal.

The perceptual presentation of interior design is to represent an interior space planned by a designer as if people see it in reality. The perceptual presentation methods that have developed are perspectives, full-scale models, small-scale models, photography of models, video taping of models, computer images, computer animation, and virtual reality. The purpose of this study is to investigate limits of those perceptual presentation methods according to their characteristics. The methods have characteristics that are either static or dynamic and either monoscopic or stereoscopic. In terms of representing interior spaces and perceiving interior spaces, the dynamic characteristic is more helpful than the static characteristic because the dynamic characteristic provides consecutively changing views of interior spaces when people walk around within the spaces. The stereoscopic characteristic is more helpful than the monoscopic characteristic because the stereoscopic characteristic provides the binocular depth perception. Full-scale models, small-scale models, virtual reality that have dynamic and stereoscopic characteristics, are most effective. The next effective methods are video taping of models and computer animation that have dynamic and monoscopic characteristics. The last effective methods are perspectives and photography of models that have static and monoscopic characteristics. But the most effective methods can not be said that those are perfect because each of them still has limits. Designers have to consider the limits of each perceptual presentation method to find a way that shows their designs most effectively. To develop the perceptual presentation methods of interior design, researchers should focus on the helpful characteristics that are dynamic and stereoscopic.

This study examined the fashion culture of 20-30s working women through clothing norm relationships in the workplace. A literature research was conducted along with qualitative research, in-depth interviews in order to understand the domestic working environment and fashion culture such as lifestyle and consumer culture characteristics of 20-30s working women. The results were: First, it showed that the increased number of members having various inclinations caused subcultures through an increase of women's economic activities and transition to a knowledge-information society in domestic work places that changed into a business casual that recognized employees' autonomy and diversity. Second, in the working place, clothing norms coexist as stipulated by statutes, company rules, and official documents as well as others implied by experiences of sanction against members. Workplace closing norms are classified into norms of exposure that draw attention to clothes and casual clothes. Third, it showed that factors pressuring clothing norms are classified as external pressures and by spontaneous self-censorship that cause conflict and confusion with working women's fashion according to the degree of pressure. Two kinds of pressure by others (or types of departments and members) were observed.

The Korean Conflict of Laws Act recently incorporated much of the European Union's recent revision in "EC Convention on the Law Applicable to Contractual Obligations (Rome 1980)"(hereinafter Rome Convention). With the revision of Rome Convention applied to contractual obligations,"Regulation (EC) No 593/2008 of the European Parliament and of the Council of 17 June 2008 on the law applicable to contractual obligations (Rome I)"(hereinafter Rome I) has taken effect on December 2009. Before the effectivation of Rome I, "Regulation (EC) No 864/2007 of the European Parliament and of the Council of 11 July 2007 on the law applicable to non-contractual obligations (Rome II)"(hereinafter Rome II) has come into effect on January 2009. This means the revision of certain rules and its practical implications need an in-depth study on governing law rules under Rome I which provides newly effected governing laws applicable to contractual obligations. Moreover, uniform choice of law rules on non-contractual obligations needs to focus especially on marine insurance contract. Where policy assignment and subrogation causes, how to decide the governing law which will be applied to the insurer as a third party? This article attempts to analyze emerging legal issues in legal regimes determining choice of law, especially those in international marine insurance contracts. This will help Korean practitioners to be dialed in legal affairs under English Law as the governing law in their contracts.

This paper studied the apparel product attributes that women in the new elderly generation require in formal wears and in casual wears. The purpose of this study was to provide the design guideline when considering the changing and diverse buying patterns of the new elderly female consumers as opposed to the traditional elderly generation. We employed a qualitative study methodology of one-on-one in-depth interview with open coding. Between August 10 and October 3 of 2012, we interviewed sixteen female consumers of age 60 or above residing in the metropolitan area who considered themselves as young-minded. Our findings were as follows: The consumer-required attributes that the new elderly women wanted to present have five dimensions of symbolism, aesthetic, fitness, usefulness, and maintenance. The main focus of the apparel product attributes that the new elderly women wanted was the dimension of symbolism in formal wears and the dimensions of usefulness and maintenance in casual wears. The new elderly females were the emerging group of consumers of diversified clothing products who emphasized overall balance and wore appropriately for occasions. Apparel products for the new elderly females should incorporate the design attributes that they want as well as the overall balance among individual wears.

Purpose: This study aimed to provide baseline data for implementing advanced life-support for 119EMTs. This is done with an in-depth examination of the emergency care experiences of the 119EMTs on-site and during transportation. Methods: Interviews were conducted with twelve 119EMTs, and the data were analyzed using the phenomenological method. Results: The 34 topics had 19 sub-components and were analyzed according to seven categories: 'A work environment where you cannot focus only on emergency care on-site and during transportation', '119EMTs struggling with manpower shortage', 'Current status of education blocking the upward standardization of 119EMT', 'Implementation of professional emergency care was held back due to the limited legal scope of 119EMT', 'Medical oversight makes it difficult to implement emergency care due to low flexibility', '119EMTs who cannot choose hospital selection and find it difficult to receive help', 'An evaluation system not reflecting reality at all that only leaves high scores'. Conclusion: This study was undertaken to implement specialized emergency care for 119EMTs; not only the necessity of reviewing the expansion of the work scope of 119EMTs but also the necessity of effective 'Medical Oversight system' reorganization raised as well.

A new type of horizontal submerged break water or fixed structure to control waves near coastal area is introduced to focus wave energy before or behind it. Intentionally, the water depth near the structure is changed gradually to get a refraction and diffraction effect. The concentration of wave energy due to the structure was analyzed for the selected design of structure. The shape of the submerged structure in consideration is a circular combined with elliptical curve not to cause reflection of waves at the extreme edge of the structure but cause wave scattering. The direction of the structure against the incident wave is changed easily in the model Applying a regular wave train the following were examined. 1) whether a crescent plain submerged structure designed by the wave refraction theory can concentrate wave energy at a focal zone behind and before it without wave breaking phenomenon. 2) Location of maximum wave amplification factor in terms of the incident wave direction, wave period, etc. In any event the study would contribute to control waves near coastal area and to protect a beach from erosion without interruption of ocean view it is an useful study for the concentration of wave energy efficiently with the increase of wave height.
