Objectives: This study investigated whether the Minnesota Multiphasic Personality Inventory-Adolescent Restructured Form (MMPI-ARF) can differentiate between two groups of adolescents, one diagnosed with internalizing disorders and another with externalizing disorders, and examined the clinical utility of the MMPI-A-RF by examining which subscales can significantly discriminate between these two groups. Methods: A total of 105 adolescents aged 13-18 years completed the MMPI-A-RF (53 internalizing disorder and 52 externalizing disorder groups). Independent t-test, chi-square test (χ²), and discriminant analysis were used to examine whether MMPI-A-RF can distinguish between the two groups. Results: Sixteen MMPI-A-RF scales best predicted differences between the groups with internalizing and externalizing disorders. Fourteen scales (Higher-Order Scale [Emotional/Internalizing Dysfunction], Restructured Clinical [RC] Scale [RC demoralization, Somatic Complaints (RC1), and Low Positive Emotions (RC2)], Personality Psychopathology Five Scale [Introversion/Low Positive Emotionality-Revised, Negative Emotionality/Neuroticism-Revised], Somatic/Cognitive Scale [Malaise, Head Pain Complaints, and Gastrointestinal Complaints], Internalizing Scale [Stress/Worry, Self-Doubt], Externalizing Scale [Negative School Attitudes], Interpersonal Scale [Social Avoidance, Shyness]) were associated with the internalizing disorder group, whereas two scales (Externalizing Scale [Conduct Problems, Negative Peer Influence]) were associated with the externalizing disorder group. Conclusion: The MMPI-A-RF can be an efficient assessment tool for a quick diagnosis as it can classify individuals with internalizing and externalizing disorders in clinical settings that lack a variety of assessment tools for children and adolescents.

Service quality is defined as the perceived difference between performed service and expected service. In this paper, theme park service quality is conceptualized in relation to consumer's total satisfaction on theme park visitation. A 20-item scale was constructed to measure Theme Park Service Quality. The following four steps were employed in developing the service quality measure: 1)identification of service quality dimensions, 2)development of scales from a set of items describing the dimensions, 3)empirical verification of the scale's construct validity which refers to dimensionality, convergent validity, and nomological validity, and 4)confirmation of the utility. The scale was found to be an empirically valid and reliable evaluation tool for service quality enhancement. In addition, the scale would be an useful criterion for market segmentation and positioning.

To provide a specified power quality under electric market system is becoming an important issue for customers and utility company. However, there is no realistic infra-structure to design a power system for the specified power quality. Present electric market is operating under the economic point of view. The low power price could be attractive, but the effect of low price could result the lower power quality for the long time and threat power system security. This paper presents a model which conceptualize the dynamic power quality control mechanism to minimize total cost of a society which is affected electric power quality. This model aims to produce a basic infra-structure to balance cost and quality under the electric market system.

The paper is on the record of radiography the patients with SIEMENS ANGIOSTAR/POLYTRON S PLUS angiosystem with DSA system in the Chonbuk National University Hospital from October 1993 to June 1994. The results are as follow : 1. Among the total No, 836 case of utilization, angiography are 316(37.8 %), interventional radiography are 256(34.2 %), and dacryocystography and sialography are 168(20/1 %). Therefore non-angiogrlphy procedure are incerasing. 2. The aomunt of contrast material used are half as much as conventional angiovascular system. 3. The amount of film consumed are $10{\sim}15%$ of that of conventional angio vascular system and reduction of procedure time are $40{\sim}50%$. 4. Admitting that dignostic utility is in the utilization by examination region, there should be technological study which deal with fine vessel and motion artifact problem.

An accurate system for predicting the survival of patients with oral squamous cell carcinoma (OSCC) will be useful for selecting appropriate therapies. A nomogram for predicting survival was constructed from 96 patients with primary OSCC who underwent surgical resection between January 1994 and June 2003 at the Yonsei Dental Hospital in Seoul, Korea. We performed univariate and multivariate Cox regression to identify survival prognostic factors. For the early stage patients group, the nomogram was able to predict the 5 and 10 year survival from OSCC with a concordance index of 0.72. The total point assigned by the nomogram was a significant factor for predicting survival. This nomogram was able to accurately predict the survival after treatment of an individual patient with OSCC and may have practical utility for deciding adjuvant treatment.

The purposes of this study were to identify the brand positioning of children's wear according to fashion life style and to construct brand positioning maps by using multidimensional scaling (MDS). A total of 222 responses were collected from married women aged 25 to 35 through questionnaire. Cluster analysis on fashion life style factors identified three groups: Fashion Indifference group (34%), Fashion & Individuality Oriented group (27%) and Rationality Oriented group (37%). ANOVA revealed significant differences among the three groups on the six fashion life style factors. MDS analysis showed that three segmented groups evaluated nine children's wear brand for seven attributes(color, design, price, utility, quality, brand name, fashion).

This research focuses on the development and empirical validation of a model of software piracy behavior on the basis of deterrence theory, expected utility theory and the theory of reasoned action. The total of sample numbered 86 and PLS (Partial Least Square) was utilized for analysis. The test of this study revealed that punishment severity was the greatest significant factor to influence to software piracy and subjective norms was also significantly related to it. However punishment certainty and software cost do not significantly affect to software piracy.

This study, a sub-one of comprehensive research works titled under “Rural Resources Evaluation System”, tried to verify utility/applicability of the developed model system through the case study works on 3 sample villages, Backya, Uyan and Suyu, representing the lowland, upland and seashore villages respectively. From the various surveying and collecting works including the official/statistical data collection, map analysis, insitu investigation, field survey and written material review, the original data set were obtained and manipulated into final input data for resources grading. After then, by the automatized calculation procedure of “Rural Resources Evaluation System”, score results for resources evaluation were finally produced with the total maximum score being 1,000. Through comparing works among score results of 3 case villages and between score results and areal characteristics of each case village, the applicability of the system developed in this study was well confirmed.

Phase angle in grid-connected inverter is important information for current control. When different loads are connected to PCC(Point of Common Coupling) of grid, distorted grid voltage is taken place by load utility generating distorted current. Especially, in case the grid voltage is distorted by low order frequency such as $3^{rd}$, $5^{th}$ harmonic, phase angle of PLL output is distorted. This paper analyze problem of current THD(Total Harmonic Distortion) due to distorted phase angle by distorted grid voltage, and propose control method compensating this problem. Also, it‘s validity is verified by simulation and experiment.

This paper proposes an exercise recommendation system for treating obesity that provides systematic recommendations for exercise and diet. Five body indices are considered as indicators for recommend exercise and diet. The system also informs users of prohibited foods using health data including blood pressure, blood sugar, and total cholesterol. To maximize the utility of the system, it displays recommendations for both indoor and outdoor activities. The system is equipped with multimode sensors, including a three-axis accelerometer, a laser, a pressure sensor, and a wrist-mounted sensor. To demonstrate the effectiveness of the system, field tests are carried out with three participants over 20 days, which show that the proposed system is effective in treating obesity.
