Besides from medical data, the patients who were previously called as attention disorder, mental instability, moral imbeciles, or moral defectives, can also be identified by exploring literatures and historical figures. In the past, as we can notice from the titles, they were recognized as a 'moral defect group'. And rather than treating them, separation from the society was the main solution. After the endemic encephalitis from 1917 to late 1920s, however, many survivors suffered from behavioral problems similar to those of the previous 'moral defect group' and studies on the relationship between brain damage and behavior problems were started henceforth. After being known as the 'minimal brain dysfunction', it was developed into the current attention-deficit/hyperactivity disorder. While the disease concept changed and developed over time, after numerous trials and errors, treatment medication starting from central nervous system stimulants such as amphetamine and methylphenidate is used for treatment in children and adult patients with ADHD, and most recently non-stimulants such as atomoxetine has become the one of the first line treatment options. Although we went through a thorough verification process of the safety and efficacy of the medication by contemplating the historical development process, we believe that adjustment is needed for remaining concerns on medication abuse and slight differences in disease paradigm and therapeutic philosophy depending on cultures.

In order to explore vegetation adaptation to climate variability and the impacts on water balance dynamics, the inter-regional and the inter-annual variability of both water availability and vegetation productivity are investigated. The Horton index, which is the ratio between actual evapotranspiration and catchment wetting as a measure of vegetation water use at catchment-scale, is revisited to quantify the effects of growing-season water availability on hydrologic partitioning at catchment scale. It is shown that the estimated Horton index is relatively constant irrespective of inter-annual climate variability. In addition, the Horton index is compared with catchment-scale vegetation rain use efficiency. The results show that there is an interesting pattern in the response of vegetation water use to water availability. When water becomes the limiting factor for vegetation productivity, the catchment-scale vegetation rain use efficiency converges to a common maximum value in agreement with earlier findings at the ecosystem level.

Background: The purpose of this study is to assume appropriate outpatient consultation time for each clinical department on the basis of measured outpatient consultation time and satisfaction of outpatient. Methods: We surveyed the feeling and satisfactory outpatient consultation time, satisfaction, revisiting intention and recommendation to others to 1,105 patients of single general hospital in Gyeonggi-do and measured their real outpatient consultation time from October 28 to November 27 in 2013. On the basis of satisfaction, we estimated appropriate outpatient consultation time through area under the receiver operating characteristic curve in logistic regression model. Results: Feeling outpatient consultation time was 5.1 minutess, satisfactory outpatient consultation time which was suggested by patient was 6.3 minutes, and real outpatient consultation time was 4.2 minutes. Department which had longest real outpatient consultation time was infection (7 minutes) and department which had longest satisfactory outpatient consultation time was neurology (9.4 minutes). From the univariate and the multiple linear regression analysis, real outpatient consultation time was longer in pulmonology patient, new patient and afternoon patient, satisfactory outpatient consultation time was longer in infection, neurology, neuropsychiatry, neurosurgery, and rehabilitation patient. Appropriate real outpatient consultation time was suggested as 5.6 minutes which differentiated high and low satisfied patient group. However, we could not assume appropriate outpatient consultation time for each clinical department because the number of patient who had bad satisfaction was too low. Conclusion: To improve patient's satisfaction, we hope outpatient reservation system is operated as each patient's outpatient consultation time is at least 5.6 minutes.

The objective of this study is to examine how the factors influence each other by determining the appropriate measurement standard in fast food restaurants based on the evaluation of attributes, perceived pricing, value, satisfaction and intention of revisit, and present an effective marketing strategy for fast food restaurants based on the analytical results by patrons and market segmentations. The study surveyed 195 subjects and processed the result using SPSS for Win. V. 12.0. For statistical analysis, Frequency, Factor Analysis, Reliability Analysis, and Regression Analysis were put into operation. As a result of the Factor Analysis of the evaluation of attributes, 3 factors have been extracted. The results showed that restaurant attribution evaluation had a positive effect on the perceived value($R^2adj=0.357$, p=0.000), satisfaction($R^2adj=0.346$, p=0.000) and intent of revisiting($R^2adj=0.389$, p=0.000); perceived pricing had a positive affect on the perceived value($R^2adj=0.464$, p=0.000), satisfaction($R^2adj=0.113$, p=0.000) and intention of revisit($R^2adj=0.276$, p=0.000); perceived value had a positive affect on satis-faction($R^2adj=0.327$, p=0.000) and intention of revisit($R^2adj=0.515$, p=0.000); and satisfaction had a positive affect on intention of revisit($R^2adj=0.442$, p=0.000).

This study surveyed university students in the Seoul and Kyonggi areas about their purchasing types and sale strategies for high quality ice cream products. The desire to buy new high quality ice cream was "moderate" (35.4%) followed by "quite a lot" (29.4%), showing that the students' interests and their desires for new high quality ice cream items were high. Among things to consider when buying ice cream, 39.2% answered that "taste" was most important, When the subjects were asked if they planned on revisiting an ice cream shop chain. 38.6% answered "quite a lot" or "very much" reflecting that their opinion on the image and service of the ice cream shop chain were very good. As for the influence of seasons on their purchasing of ice cream products, three times more students responded "quite a lot" or "very much" at 51.6% compared to "somewhat little" or "very much" (17.8%), showing that the subjects were responsive to seasonal influences, The subjects were also three times more likely (73.0%) to visit a cafe-type high quality ice cream store chain, Therefore such cafe-type chains are a way to increase sales and to overcome seasonal influences on purchasing. Finally the favorite food to eat with ice cream was cookies (51.3%).

Previous studies showed that many secondary school students and teachers have difficulties in distinguishing the phenomena of dissolution and diffusion, as well as the phenomena of diffusion and effusion. In this study, currently accepted term definitions of dissolution, diffusion and effusion were searched from the IUPAC Gold Book and the physical chemistry textbooks, and the points to differentiate the definitions were sought. Also, the term definitions of these three phenomena in the secondary school text books and the college general chemistry textbooks were surveyed and compared to the currently accepted definitions. It was found that dissolution is formation of one new phase from mixing two phases, while diffusion is the migration of matter down from the concentration gradient. The "concentration gradient" is considered to be a key point to distinguish diffusion from the dissolution. However, the concentration gradient was not mentioned in the definitions of diffusion in most of the secondary school textbooks and the college general chemistry textbooks. Effusion is differentiated from diffusion by the gas molecules escaping from the container through a tiny hole without collision. The definition of effusion was not found in most of the secondary school textbooks.
