Attention-deficit hyperactivity disorder (ADHD) is a neuropsychiatric disorder that begins in early childhood and can persist throughout adulthood. ADHD causes difficulties in various area of life, such as academic achievement, peer relationships, family functioning, employment and marriage. Although ADHD is known to respond well to medication, such treatment is more effective when combined with psychosocial (non-pharmacologic) therapy in terms of alleviating the core symptoms and improving appropriate functions. Psychosocial treatment interventions are divided into psychoeducation, behavioral parent training, school intervention, cognitive behavior therapy, social skill training, parent-child interaction therapy, play therapy, other treatments (coaching, complementary and alternative medicine), neurofeedback and Cogmed. Adult ADHD cognitive behavioral therapy is described separately. These practice parameters summarize the evidence for psychosocial treatment. Based on this evidence, specific recommendations are provided for psychosocial interventions.

Commercial spaces are very sensitive in terms of trend and uniqueness, and many elements expressing space coexist together with brilliant ideas aiming to attract consumer attention and even induce sudden desire of purchase. Coexistence in space is expressed in various ways and out of those ways, representation by material is especially apparent. The application of material does not individually influence the expression of space, but the characteristics of multiple materials applied contribute to the distinction of space through mutual communication. This study intends to analyze how conversion is centered to express the distinction of space through materials communicated in space. The detailed study results are as follows. First, the conversion expression method of material resulted as 'Substitution', 'Contrast', 'Assimilation', 'Creation'. These four was divided and analyzed into 'Time', 'Space', 'Genre'. As a result of this analysis, such significances were shown as 'Contrast' in 'Time', 'Substitution' in 'Space', and 'Assimilation' in 'Genre'. Second, the conflict due to heterogeneity by conversion of 'Contrast' in 'Time' through past and current materials appeared to induce interest amongst consumers. Third, within 'Space', 'Substitution' of natural/artificial materials was noticeably applied. This is evaluated as a constructive way of expressing natural forms into artificial forms further intending to provoke attention and stimulate emotion. Fourth, in conversion through 'Assimilation' in 'Genre', rather than using materials only from other areas, synchronizing it by combining architectural materials is an effective method. Such results are thought to be a distinctive design method that draws attention of customers by communicating disparate materials in commercial space. Thus, the study results are expected to be utilized as an elementary resource in designing commercial space with character and high satisfaction.

Purpose: The purpose of this study was to use meta-analysis to examine recent domestic articles related to attention deficit hyperactivity disorder (ADHD) in school-age children. Methods: After reviewing 213 articles published between 1990 and 2009 from and cited in RISS, KISS, and DBpia, the researchers identified 24 studies with 440 research variables that had appropriate data for methodological study. SPSS 17.0 program was used. The outcome variables were divided into five types: Inattention, hyperactive impulsive, intrinsic, extrinsic, and academic ability variables. Results: Effects size of overall core symptoms was 0.47 which is moderate level in terms of Cohen criteria and effects size of overall negative variables related ADHD was 0.27 which is small level. The most dominant variable related to ADHD was obtained from hyperactive-impulsive (0.70). Also academic ability (0.45), inattention (0.37), and intrinsic variables (0.29) had a small effect whereas extrinsic variables (0.13) had little effect on descriptive ADHD study. Conclusion: The results reveal that ADHD core symptoms have moderate effect size and peripheral negative variables related ADHD have small effect size. To improve the reliability of the meta-analysis results by minimizing publication bias, more intervention studies using appropriate study designs should be done.

The study is to find relative EEG power spectrum and pattern of coherence discriminating attentive and inattentive hand movements. Eight undergraduate students aged from 20 to 27 who had not hand disability participated in this study. Participants were asked to perform visuo-motor task. EEG was measured at C3 in 10~20 international system and four areas orthogonally directed 2.5cm away from C3. Significant result discriminating movement and rest was found through coherence analysis between movement areas or movement area and non-movement area, but was individually different. Because it was anticipated that major factors caused by the differences among individuals were attributed to the attention of the subjects, relative power of alpha and beta bands was identified. As a result, significant relative powers of alpha and beta bands were found in a group of high coherence level, but were not found in a group of low level. Next, participants were divided into two groups according to relative powers of alpha and beta bands. The comparison between two groups was performed. As a result, the coherence of the alpha band in the attentive group was greater than that of the inattentive group. It was found that the coherence of the beta band in the inattentive group was happening. Therefore, individual differences of coherence were influenced by attention. The significant coherence patterns that could discriminate attentive movement and inattentive movement were found.

최근 관심이 약화되고 있지만 정보격차는 정보사회 실현의 중요한 장애요인으로 지적되어 왔다. 정보격차에 대한 상반된 설명방식이라고 할 수 있는 낙관론과 비관론은 공통적으로 정보격차를 초래하는 객관적 조건에 초점을 맞추어 왔다. 그러나 접근 가능성은 객관적 조건뿐만 아니라 개인적 차원의 필요성에 대한 인식이나 의지와 같은 주관적 조건에 의해서도 달라질 수 있다는 사실은 경시되어 왔다. 인식이나 의지에 따르는 선택은 접속과 비접속을 결정하는 중요한 요인으로 작용할 수 있다. 미국의 경우 잠재적 이용자의 50% 이상이 스스로의 의지와 선택에 의해 인터넷을 사용하지 않는 것으로 알려져 있다. 우리나라의 경우에도 인터넷 사용자를 대상으로 한 조사에 따르면 '필요성을 느끼지 못해서'가 인터넷을 이용하지 않는 가장 중요한 이유로 나타났다. '이용할 시간이 없어서'라고 선택한 경우도 지속적으로 감소하고 있기는 하지만 상당한 비율을 차지하고 있으며 비 이용자들 중에서 차지하는 상대적 비중은 지속적으로 증가하고 있다. 선택에 의한 정보통신 기술의 비 이용자들을 정보격차의 범위에 포함시켜야 할 것인가의 문제가 있기는 하지만 정보사회로의 진행과정에서 선택에 의한 비 이용에 관심을 기울일 필요성은 분명한 것으로 보인다.

Objectives: Childhood adversity is a risk factor for anxiety symptoms, but it affects anxiety symptoms in attention-deficit/hyperactivity disorder (ADHD). The current study aimed to examine the association between childhood adversity and anxiety symptoms in participants with and without ADHD. Methods: Data were obtained from a school-based epidemiological study of 1017 randomly selected children and adolescents. The ADHD and non-ADHD groups were divided using the Diagnostic Interview Schedule for Children Predictive Scale (DPS). The DPS was also used to assess comorbidities such as anxiety and mood disorders. The childhood adversities were assessed using the Early Trauma Inventory Self Report-Short Form, and the anxiety symptoms were assessed using the Screen for Child Anxiety Related Disorders. Linear and logistic regression models were used to investigate the association between childhood adversity and anxiety in the ADHD and non-ADHD groups with adjustments for age and sex. Results: This study found that the ADHD group did not show any significant association between anxiety symptoms and childhood adversities, whereas the non-ADHD group always showed a significant association. In a subgroup analysis of the non-ADHD group, the normal group without any psychiatric disorders assessed with DPS demonstrated a statistically significant association between childhood adversities and anxiety symptoms. These results were consistent with the association between childhood adversities and anxiety disorders assessed using DPS, as shown by logistic regression. Conclusion: The association between anxiety symptoms and childhood adversities statistically disappears in ADHD; ADHD may mask or block the association. Further longitudinal research is necessary to investigate this relationship.

In response to recent changes in gender equality and social awareness among female college students, we sought to investigate whether there were corresponding changes in their preferred fashion styles and items. A survey was conducted with 200 women in their twenties to determine whether they were aware of gender equality and social change, as well as their preferred fashion styles and items at both the time of college admission and the current time. Awareness of gender equality was divided into two factors: feminism and a perceived increase in women's social power. A significant difference was observed in the fashion styles of female college students in their twenties between the time of admission and the current time. Compared with the past, the preferred style has changed to gender-neutral rather than feminine, useful rather than aesthetics, character rather than fashion, sporty rather than elegance, and casual rather than formal. Preferred items included pants rather than skirts, sneakers rather than shoes, socks rather than stockings, long skirts rather than short skirts, and backpacks rather than handbags. The level of attention paid to campus attire per week decreased over time. No correlation was found between gender equality awareness and preferred fashion style, while feminism was correlated with preferred fashion items. The degree to which attention was paid to campus attire per week was correlated with feminism, but was not correlated with a perceived increase in womens' social power.

Social media have been rapidly and widely adopted in various areas, and tourism industry can be one of potential growing areas. Tourist and travelers would like to share their photos and stories as well as find others' experiences. People are doing their activities through social media. Regarding relaxing entertainments, information sharing, escapism, social interaction, tourism activities are being paid attention by majority of users in social media. However, Although people have various motivation for using social media, academically researchers have not actively studied on the phenomenon arising from tourism industry. Therefore, this study aims to the reasons for tourism information searching motivational factors of social media that influence perceived value and its consequences such like before-searching, during-searching, and after-searching and divided social media into two types according to the level of social presence, and then empirically verified them. Antecedent variables divided into benefits including perceived usefulness and information quality and sacrifices including complexity and perceived effort. Our analysis results show that both of dimensions had the greatest effect on perceived value of social media use, which affect the consequences.

Digital watermarking techniques are attracting attention as a proper solution to protect copyright for multimedia data. This paper proposes a new audio watermarking method based on Discrete Cosine Transformation (DCT) and Discrete Wavelet Transformation (DWT) for copyright protection. In our proposed watermarking method, the original audio is transformed into DCT domain and divided into two parts. Synchronization code is applied on the signal in first part and 2 levels DWT domain is applied on the signal in second part. The absolute value of DWT coefficient is divided into arbitrary number of segments and calculates the energy of each segment and middle peak. Watermarks are then embedded into each middle peak. Watermarks are extracted by performing the inverse operation of watermark embedding process. Experimental results show that the hidden watermark data is robust to re-sampling, low-pass filtering, re-quantization, MP3 compression, cropping, echo addition, delay, and pitch shifting, amplitude change. Performance analysis of the proposed scheme shows low error probability rates.
