  • Electroencephalography (EEG) measures neural activation due to various cognitive processes. EEG and event-related potentials (ERPs) are widely used in studies investigating psychopathology and neural substrates of psychiatric diseases in children and adolescents. The present study aimed to review recent ERP studies in child and adolescent psychiatry. ERPs are non-invasive methods for studying synaptic functions in the brain. ERP might be a candidate biomarker in child-adolescent psychiatry, considering its ability to reflect cognitive and behavioral functions in humans. For the EEG study of psychiatric diseases in children and adolescents, several ERP components have been used, such as mismatch negativity, P300, error-related negativity (ERN), and reward positivity (RewP). Regarding executive functions and inhibition in patients with attention-deficit/hyperactivity disorder (ADHD), P300 latency, and ERN were significantly different in patients with ADHD compared to those in the healthy population. ERN showed meaningful changes in patients with anxiety disorders, such as generalized anxiety disorder, separation anxiety disorder, and obsessive-compulsive disorder. Patients with depression showed significantly attenuated RewP compared to the healthy population, which was related to the symptoms of anhedonia.

  • Theory of mind (ToM) is the ability to infer one's own and other people's mental states such as beliefs, desires, and intentions. Although the majority of research in ToM has focused on young children or autistic individuals, several studies have investigated ToM in normal old age and in the demented elderly. This article provides an overview on existent findings of theory of mind in aging populations and suggests future directions for research including applying neuroimaging techniques and real-life tasks. It is still unclear how ToM in aging is associated with other aspects of cognition. However, it is expected that ToM perspective on aging will increase our understanding of aging of cognition and social functioning.

  • It is not known whether negative symptoms and cognitive functions are dissociable or improvements in symptoms are reflected in improvements in cognitive functions in chronic schizophrenic patients. We administered clozapine to evaluate its effect on cognitive functions in chronic schizophrenic patients and to show correlations between improvement in psychotic symptoms and in cognitive functions. Neuropsychological tests such as Wisconsin Card Sorting Test, Digit Span test and Judgment of Line Orientation Test were applied to 16 chronic schizophrenic patients at baseline and after 9 months of treatment with clozapine. Using BPRS we assessed psychopathology before initiation of clozapine and at 9 months. Clozapine improved both positive and negative symptoms in chronic schizophrenic patients significantly. After nine months of clozapine treatment, significant improvements occurred in attention, short-term memory and visual perception ability. And interestingly we noted the trend of improvement in executive functions even though they were not statistical significant. Any significant correlations between the clinical improvement and change in congnitive functions were not observed. Long-term treatment with clozapine improved parts of cognitive functions of chronic schizophrenics. The results of the study suggest that deficits in simple cognitive functions as well as psychotic symptoms are improved after 3 month period of short-term treatment, but executive functions requiring more sophisticated processing of information could be improved after more than 9 months of long-term treatment.

  • In democracy basic rights such as political equality and participation through elections have been respected, opportunities of corporation and opposition have been guaranteed, and ability of self-learning and self-correction have been developed. These positive factors give preconditions for the welfare development in the democratic state. Because in this state adults get the suffrage and the open competition for official positions induces political parties use social policies as means to win the election. That is to say, political parties have an incentive to use various social policies to win the election. Democracy, therefore, has affinity with social policy. The affinity between democracy and social policy can be found also in Korea which was democratized in 1987. But, in Korea, the positive relationship between democracy and social policy is very weak due to the problem of constitutional structures. Korean Parliament usually enacts abstract social act and delegates the right to fill concrete contents of the social acts to the executive. Delegation itself has no problem, but excessive delegation is a problem since the executive can overuse its discretion as sacrificing the social rights of the citizen. In addition social consensus could not be achieved in this constitutional structures, which are a obstacle to establishing a political process in the Parliament to promote the welfare development through party competition. Excessive delegation should be reduced, and the Parliament should fill concrete contents of the social acts as exercising its legislative power more. Then a mechanism of welfare development can be launched in Korea.

  • This study aims to suggest better future-oriented improvements by considering the traits and changes of the curriculum of the courses related to the field of fashion. To get the best results from the study, out of all the fashion-related majors (courses) from 4-year based universities in Korea, 65 was selected and divided into 24 courses in the category of clothing & textiles, 34 courses in the category of fashion design and 7 courses in the category of fashion industry in 7 universities, and their education goals and contents of the curriculum posted on the internet homepage of each university were analyzed. The results of the study are as follows: Firstly, with the result from analyzing what the core terms have in common, which are used to express the educational purposes of fashion-related courses in Korea, the ideal type of talents that most of the fashion-related courses tend to pursue can be said to be those who are equipped with a sense of future-oriented creative direction and international communication capability, based on a multidisciplinary general capability, a professional executive ability, an information-analytic ability and an ability of planning, as well as in possession of a sense of beauty, creativity and a scientific mind. Secondly, with the traits of the curriculum of courses in each category, it was found that the category of clothing & textiles courses belongs to colleges of human ecology the most, and in terms of major subjects, the relative importance of clothing science seemed high compared to other school categories while the category of fashion design courses belongs to colleges of art, modeling or design the most, and in terms of major subjects, the scope of dress design appeared the widest, and finally the category of fashion industry courses belongs to colleges of natural science the most, and the relative importance of marketing seemed quite high. Moreover, with the result mentioned earlier, It was found that the names of departments and majors of fashion-related courses are differentiated, depending on what kind of college they belong to, and their curriculum have been differentiated to some degree accordingly. Thirdly, as shown above, Korean universities have attempted to make a lot of changes in the curriculum of fashion-related courses according to changes of the age, compared to what they did in the past, but they have still seemed to lack many things for the cultivation of talents fit for their educational purposes. Through the result from investigating both the changes of the current age and the directions in developing the curriculum, the study came to conclusion that each university in Korea should develop the major curriculum of fashion-related courses that are more sophisticated and intensive fit for the its department name and educational purposes.

  • Background: In order to obtain a deeper understanding of an incident, it needs to be investigated to "peel back the layers" and examine both immediate and underlying failures that contributed to the event itself. One of the key elements of an effective accident investigation is recording the scene for future reference. In recent years, however, there have been major advances in survey technology, which have provided the ability to capture scenes in three dimension to an unprecedented level of detail, using laser scanners. Methods: A case study involving a fatal incident was surveyed using three-dimensional laser scanning, and subsequently recreated through virtual and physical models. The created models were then utilized in both accident investigation and legal process, to explore the technologies used in this setting. Results: Benefits include explanation of the event and environment, incident reconstruction, preservation of evidence, reducing the need for site visits, and testing of theories. Drawbacks include limited technology within courtrooms, confusion caused by models, cost, and personal interpretation and acceptance in the data. Conclusion: Laser scanning surveys can be of considerable use in jury trials, for example, in case the location supports the use of a high-definition survey, or an object has to be altered after the accident and it has a specific influence on the case and needs to be recorded. However, consideration has to be made in its application and to ensure a fair trial, with emphasis being placed on the facts of the case and personal interpretation controlled.

  • Hospitality industry offers internship programs to the students who have studied hospitality related majors in a college, giving them opportunities to improve their executive ability through academic knowledge. However, it has been found that there are several issues against the purposes such as unconcern, work burden, inadequate reward, and discontent. In this respect, this study aims to suggest the advisable solutions to achieve the original purposes of an internship program by examining the effects of the perception of the internship program, anticipation for it, satisfaction with it, and job pursuit intentions after finishing it. Positive factors for the perception of internship training are businesses, allocation of departments, working environments, students abilities, and academical knowledge while its term and reward from it are not the influential factors. The positive perception of the internship training is influenced by affirmative importance-performance thinking, but positive job pursuit intentions is not affected by affirmative perception of the training.

  • In this paper, the activities carried out within the EU funded Clean Sky Joint Technology Initiative (JTI GRA) Project and aimed at developing a morphing flap, are illustrated. The reference device is a regional aircraft single slotted flap, enhanced with deforming capabilities to obtain improved hyper-lift performance. The design started with the identification of the internal architecture, intended to allow camber variations. A concentrated-hinge architecture was selected, for its ability to fit different curvatures and for the possibility of easily realizing an "armadillo-like" configuration, then avoiding the use of a complicate deformable skin. The flap layout is made of segmented ribs, elastically hinged each other and span-wise connected by conventional spars. Relative rotations of the rib elements are forced by SMA structural actuators, i.e., cooperating in the external loads absorption. Super-elastic SMA are used to make up recovery elastic elements, necessary to regain the original shape after activation. These further elements in turn contribute to the overall flap rigidity. After assessing the hinge number and the size of the SMA active and passive elements, the advanced design phase was dealt with. It was aimed at solving manufacturing issues and producing the executive drawings. The realized demonstrator was finally tested in lab conditions to prove its functionality in terms of whether target shape actuation or attained shape preservation under loads. On the basis of the numerical results and the experimental outcomes, precious hints were obtained for further developments of the concept.
