The main purpose of this study was to identify the effect of hand massage on pain and anxiety related to chest tube removal in patients with a lobectomy. The research design of this study was a nonequivalent control group non-synchronized design. Of the twenty nine adult subjects, fourteen were assigned to the experimental group and fifteen to the control group. The data were obtained over 3 months from a medical center in Seoul. The instruments used to assess trait state anxiety was the Spielberger Trait-State anxiety Inventory. For pain and psychological anxiety. The Visual Analogue Scale was used. Hiko analogue sphygmo-manometer(2001) was used to check blood pressure and pulse rate as indicators of physiological anxiety Subjects in the experimental group received hand massage for 5 minutes just before chest tube was removed, and subjects assigned to the control group did not receive hand massage. Data were analysed with $x^2$-test and Mann-Whitney U test using the SPSSWIN 10.0 program. The results of the study are as follows : 1. Hypothesis 1: 'there will be a significant difference between two groups in the level of pain after chest tube removal' was supported (u = 23.00, p < 0.001). 2. Hypothesis 2: 'there will be a significant difference between the two groups in the level of psychological anxiety after chest tube removal' was supported (u = 3.00, p < 0.001). 3. Hypothesis 3: 'there will be a significant difference between the two groups in physiological anxiety(systolic, diastolic blood pressure and pulse rate) after chest tube removal' was supported(u =55.50, p = 0.01 ; u = 41.50, p = 0.01 ; u = 20.50, p < 0.001, relatively). The findings of this study indicate that hand massage is effective for pain and anxiety related to chest tube removal in patients with lobectomy. Therefore, hand massage is recommended as an effective nursing intervention for relieving pain and anxiety in patients undergoing chest tube removal. Further research is needed to identify the proper duration and timing to achieve the optimal effect of hand massage. A larger subject population is required to apply the current findings to the general population. Further research is also needed to assess the effects of hand massage in other patient subsets. Finally, it would be interesting to see if the effects of hand massaging would be attenuated when performed by a non-medical specialist.

Nowadays technological instruments are advanced to measure brain waves called EEG. Also, it is important to find some facts that cause students to have mathematic anxiety (MA) and to provide remedy programs to lessen their MA in order to help students cure MA that could contribute to negative self-efficacy toward mathematics and mathematical learning. To find how they change the MA level, a small group of 11 high school students in Suwon city participated for ten weeks at the remedy program based on students' levels of MA diagnosed by MASS instrument (Ko, & Yi, 2011) and proofread by 8 advisors who worked in related research areas. The results showed that the remedy program was effective to lessen students' MA and it should provide a long term period since some negative experiences were accumulated for a long time of his or her past schooling by others such as teachers, peers, and parents. EEG showed that students got better scores on a percent of correct answers and a reaction time and some student' EEG from a group HMA became smaller heights and width in comparison of the other groups.

Objectives: Adult attention-deficit/hyperactivity disorder (ADHD) is an important mental health problem that needs resolution, especially considering the high rates of ADHD continuation from childhood to adolescence/adulthood and the high prevalence of ADHD in adults. Adults with ADHD have lifelong negative impacts and require close monitoring with long-term follow-up. Hence, the establishment of a Korean practice parameter for adult ADHD is necessary to minimize discontinuation of treatment and enable information sharing among Korean mental health professionals. Methods: The Korean practice parameter was developed using an evidence-based approach consisting of expert consensus survey coupled with literature review. Results: According to the expert consensus survey, the most commonly used diagnostic methods were clinical psychiatric interview (20.66%) and self-report scales (19.25%) followed by attention (14.71%) and psychological tests (14.24%). Key evaluation instruments currently available in Korea are the World Health Organization Adult ADHD Self-Report Rating Scale, Korean Adult ADHD Rating Scale, Diagnostic Interview for ADHD in Adults, Barkley Deficits in Executive Functioning Scale for adults, Comprehensive Attention Test, Conners' Continuous Performance Test, and the subtests of Wechsler Adult Intelligence Scale, Digit Span and Letter-Number Sequencing. Although pharmacotherapy is recommended as the first-line of treatment for adult ADHD, we recommend that it be followed by a multimodal and multidisciplinary approach including psychoeducation, pharmacotherapy, cognitive behavior therapy and coaching. Conclusion: The Korean practice parameter introduces not only general information for the diagnosis and treatment of adult ADHD on a global scale, but also the process of diagnosis and treatment options tailored to the Korean population.

Pharmaceutical compounds enter the water environment through the diverse pathways. Because their concentration in the water environment was frequently detected in the level of ppt to ppb, the monitoring system should be optimized as much as possible for finding appropriate management policies and technical solutions. One Factor At a Time (OFAT) approach approximating the response with a single variable has been preferred for the optimization of LC-MS/MS operational conditions. However, it is common that variables in analytical instruments are interdependent. Therefore, the best condition could be found by using the statistical optimization method changing multiple variables at a time. In this research, response surface analysis (RSA) was applied to the LC-MS/MS analysis of emerging antibiotic compound, sulfamethoxazole, for the best sensitivity. In the screening test, fragmentation energy and collision voltage were selected as independent variables. They were changed simultaneously for the statistical optimization and a polynomial equation was fit to the data set. The correlation coefficient, $R^2$ valuerepresented 0.9947 and the error between the predicted and observed value showed only 3.41% at the random condition, fragmentation energy of 60 and collision voltage of 17 eV. Therefore, it was concluded that the model derived by RSA successfully predict the response. The optimal conditions identified by the model were fragmentation energy of 116.6 and collision voltage of 10.9 eV. This RSA can be extensively utilized for optimizing conditions of solid-phase extraction and liquid chromatography.

Analysis on Kandinsky's Work as a Case Study of Art Therapy. This study attempts to analyze a work of W. Kandinsky, who placed great emphasis on the relationship between the form and the color of an object, from the viewpoint of art therapy. Most papers related with fine art work analysis approach it from the aesthetical point of view and there are few attempts to interpret art works in terms of art therapy. This study tries to present a new angle to the studies of art therapy Practiced up to now and research is made on its potentiality. With an analysis on the relationship between human psychology, and color and form that convey visual language, research is made on the feasibility of art therapeutic methods through the approaches based on color psychology, Gestalt theory and perception psychology. The final purpose of this study is to apply the results to the development of illustrations, education program for children, and educational instruments and toys that will promote children's healthy emotional growth based on the color psychology and the form psychology of human being. As an initial study, a piece of Kandinsky's work, titled ' CERCLES DANS CERCLE', is analyzed as a case study of art therapy both from theoretical standpoint and from the viewpoint of art therapy. Through this effort, it can be utilized as a new case study of art therapy that will influence human emotion positively and lead to healthful emotional catharsis.

The main purpose of this study is to identify the effects of a structured nursing intervention program on dysmenorrhea in middle school girls. This study employed two methods of research at the same time: a quasi-experiment pre- and post-test to use for comparison. Subjects were middle school girls assigned to the research program: 40 girls in the second grade, 40 girls in the third grade at K Girls' Middle School and H Girls' Middle School located in J city. The data were collected for 68 days from August 23 to October 30, 1999. The data were collected by observation technique and by a self-administered questionnaire. The instruments used for this study were as follows: the "Face Interval Pain Scale" menstrual pain instrument developed by McGreth(1987) and the "Menstrual Distress Questionnaire" dysmenorrhea instrument developed by Moos(1968). The dysmenorrhea knowledge instrument was developed by the researcher and refered to above. The research procedure was as follows: after preliminary examination, the experimental groups were provided educational programs with O.H.P. films developed by the researcher and with the videotape "first meeting" supported by P&G company and produced by EBS. The groups followed the educational programs twice for two weeks. At the beginning of menstruation, these subjects could choose one among the following choices: * Jacobson's progressively muscle relaxation method and massage treatment * Jacobson's progressively muscle relaxation method and hot bag treatment * Jacobson's progressively muscle relaxation method, a pain killer treatment, and massage treatment * Jacobson's progressively muscle relaxation method, a pain killer treatment, and hot bag treatment The dysmenorrhea of the control group were measured during the same period. The analysis of the collected data was done using an SPSS-PC+, descriptive statistic including real numbers, percentage, averages, standard deviations and t-test, $x^2$ test, and ANCOVA. The results of this study were as follows. (1) The knowledge level of the girls provided with the planned nursing intervention program was higher when compared to these who did not follow the educational programs. (2) The original difference in the dysmenorrhea level having been controled, the dysmenorrhea level made, nevertheless, a statistical difference between the experimental group and the control group(F=63.8, p=.00). Observed pain on quantity measurement of dysmenorrhea showed significant difference depending on the treatment(t=4.6, p=.00). In conclusion, those in the planned nursing intervention program had a higher knowledge level and fewer symptoms than the control group. Accordingly, the nursing intervention program for dysmenorrhea developed by the researcher can be effectively applied in nursing practice and can be the foundation for this kind of program.

Traditional music should be succeeded and developed through the systematic education since music represents culture and history of one country. In Korea, even through the importance of Korean traditional music has been emphasized through the seven times of revision of national curriculum, music education has been still Western-oriented. This study aims to make students have experience Uttari Samul-nori and investigate the perception changes about the Korean traditional music. It is ultimately expected that students inherit the Korean traditional music and further recreate our own traditional culture. Samul-nori class was organized in the regular music curriculum twice a week, for 10 hours and various activities were tried during that time. 1st-year high school students participated in this research and they were allowed to play Samul instruments directly and play the basic rhythm suggested in the newly designed curriculum. Before and after the research, the questionnaires were sent to examine the attitude changes toward the Korean traditional music. The result of the questionnaire are as follows: First, Samul-nori activities affect positively the students' interest in the Korean traditional music and Samul-nori itself. Second, Danso(short bamboo flute) education which has been implemented most frequently during the Korean music education, is not satisfactory to the students. Third, students were satisfied with the new teaching method of Samul-nori and most students wanted to continue to take Samul-nori class. Last, students recognized the importance of Korean traditional music education after the research activities.

The purpose of this research was to determine whether or not a education program of low back pain would have benificial effect on nurses. Nonequivalent control group pre-post test research was designed. Subjects for this study were 50 selected from nurses who work at a general hospital in Taegu. Of them, twenty seven were assigned to experimental group, twenty-three to control group. The data were collected during the period from June 27 to August 31, 1994. The instruments used in this study were Visual Analog Scale for low back pain, Sit-and-reach test for trunk flexibility, and 1 min sit up test for abdominal muscle endurance. Data related to general chracteristics and factors of low back pain were collected with questionnaire developed by this reseacher. The data were analyzed by $X^2-test$, t-test and paired t-test, using the SAS package program. The results of this study are summerized as follows : 1. The numbers of the experimental group with low back pain were not a statistically significant difference from pre to posttesting($X^2=0.77$, p=.379), and the numbers of the control group with low back pain were also not a statistically significant difference from pre to posttesting($X^2=0.09$, p=.767). 2. The severity of low back pain of the experimental group was not a statistically significant difference from pre to posttesting(t=-0.55, p=.5857), and the severity of low back pain of the control group was also not a statistically significant difference from pre to posttesting(t=-0.70, p=.3101). 3. The trunk flexibility of the experimental group was not a statistically significant difference from pre to posttesting(t= 1.08, p=.2835), and the control group's trunk flexibility was also not a statistically significant difference from pre to posttesting(t=0.85, p=.4026). 4. The abdominal muscle endurance of the experimental group was a statistically significant difference from pre to posttesting(t=-2.42, p=.0190), but the control group's abdominal muscle endurance was not a statistically significant difference from pre to posttesting(t=-0.06, p=.9556) This study suggest that replication of study with more sample and more rigid treatment should be needed. And furthermore, the longitudinal research is needed to determine the effectiveness of education program.

Electronic displays have developed as instruments that function as windows of information to satisfy the bidirectional needs of electronic device manufacturers and users. The cathode-ray tube (CRT) display once dominated the display industry. Now, the liquid crystal display (LCD) is dominant, and promising displays are competing to become the next-generation display. Displays reflect the characteristics of the information and communication technology (ICT) industries, such as technological changes, innovative features, and competitive dynamics, and have technologically evolved to dominate the industry and market through various ICT devices. This research utilizes a dominant design concept and examines the case of the flat-panel display industry to propose a comprehensive framework, which considers technological, organizational, and environmental characteristics, of the determinants influencing dominance in the technology-intensive ICT industry. The results show that a dominant design in the flat-panel display industry emerges from technological competition among several designs, based on technological characteristics and market acceptance, and dominates the industry and market by various environmental factors. Our results emphasize the difference between generic technologies and the speed of technological innovation and expand the understanding of the emergence of a dominant design. Furthermore, this paper suggests practical implications for establishing a competition strategy and strategic guidance for other ICT industries as well as the display industry.
