This study was to investigate the types of errors and the frequency of errors to understand students' solving process on the descriptive items with the students of an excellent high school which located in a non-leveling local school district of Gyunggi Province. All 11 items were developed in the equation of a circle and 120 students who attended this high school participated in solving them. The result showed a tendency as follows: Logically invalid inference(Type A, 38.83%) of errors, Omission error of the problem solving process(Type B, 25%), Technical error(Type C, 15.67%), Wrong conclusion(Type D, 11.94%), Use of wrong theorem(Type E, 5.97%), and Use of wrong picture(Type F, 2.61%). The logically invalid inference the students showed with a largest tendency was made because of the lack of reflection. This meant that this error could be corrected in a little treatment of carefulness.

Apparel purchase behaviors were investigated for the high school girls grouped by attitude toward fashion. Differences in attitudes toward fashion were also investigated among the groups determined by demographic characteristics. Data were collected by a self-administered questionnaire survey to 600 high school girls living in Seoul, and 480 were used for the data analysis. Cluster analysis, Chi-sguare analysis, ANOVA, and Duncan\`s multiple range test were used for data analysis. Technical school students and those who spending higher amount of monthly allowances showed favorable attitudes toward fashion. Based on the attitudes toward fashion, respondents were classified into 3 groups : fashion-oriented(32.3%), fashion-conformed(47.3%), and unconcerned(20.4%). Among the 3 groups, the Fashion-oriented tended to make purchase decision for clothing based on there own, or peer\`s opinions, to use personal sources for information search, to spend more money for clothing, and to consider design and brand names as the most important criteria when purchasing apparel products than the less fashion-oriented did. Among clothing styles popular to students, the most appropriately perceived for student wear were semi-formal style, and the least appropriate ones were wearing bold colored and patterned underwear for the purpose of showing out. Most of the popular styles among high school girls were perceived less than appropriate student\`s attire.

The purpose of this study was to analyzed the effects of educational recognition sub-factors (necessity, utility, value, cost, adequacy) on the field usability and satisfaction and the correlation between each factor for 220 applicants who have taken the national technical certificate of cosmetologist (make-up). In the practical courses of makeup certificate, the most-used course was selected as beauty makeup. It found for improvement need cause there was a high necessity and there was a low recognition of the cost, the number of annual written and practical test in the recognition of certification education. In field usability 'Beauty make-up utilization' showed high recognition, and it showed high satisfaction for acquisition of certificate satisfaction, 'The salary' showed low recognition. The necessity, cost, adequacy among educational recognition sub-factor of the national technical certificate had a significant positive effect on the field usability and satisfaction, and showed the most effect as adequacy on the field usability and the cost on the satisfaction. Therefore, efforts are needed to reduce acquisition costs of certificate and improve highly available theories and technique for segmentation and specialization of make-up certificate.

The aim of this study is to evaluate the axial residual stress in multi-pass drawn high carbon steel wire by using FE analysis and XRD. When FE analysis is applied to evaluate the residual stress in drawn wire of multi-pass drawing process, obtaining the reliable effective stress-strain curve at high strain is very important. In this study, a model, which can express the reliable effective stress-strain curve at high strain, is introduced based on the Bridgman correction and tensile test for multi-pass drawn high carbon steel wires. By using the introduced model, FE analysis was carried out to evaluate the axial residual stress in the drawn wires. Finally, the effectiveness of the FE analysis with the introduced stress-strain relation was verified by the measurement of residual stress in the drawn wires through XRD. As a result, the evaluated residual stress of FE analysis shows good agreement with the measured residual stress.

The purpose of this study is to identify the stressful events, students their coping methods, and to provide data which maintain and promote healthy students, mentally and physically, The data were collected from total of 481 students from a technical high school in Pusan The Questionnair survey was done from February 2 to February 14, 1988 Analysis of the data was done using descriptive statistics, frequency, ANOVA and a t-test, The findings of the research were as follows: 1) As to the general characteristics of the 481 subjects, 376 (78.2%) were boys and 105 (218%) were girls In terms of health, 93% were in poor health From the results, It seems that when students have problems, many of them seek advice from their friends while nobody seeks advice from their teachers. 2) This study found that most students have many stressful events. In boy students, the most serious events were the following, 'death of parents', 'death of brother or Sister', 'divorce of parents' In girl students, the most serious erents were the following: 'death of brother or sister', 'death or serious sickness of friend', 'death of parents'. 3) To cope With these events, boy students used positive ways such as the following, 'to listen to music', 'to bear', 'to think through the problems' To cope with stressful events, girl students used the following positive methods 'to listen to music', 'to talk with others', 'to sing', 'to sleep' and 'to weep', A small percentage of students used the following negative methods 'to drink alcohol', 'to skip school' and 'to escape from home' 4) The relationship between stressful events and general characteristics represented Significant differences in academic scores (F=1.440, p=0008), health state (F=1.388, p=0.015), and relationship with parents (F=1.685, p=0.000) The relationship between general characteristics and coping methods represented a significant difference in sex (t=-3.100, p=0.002).

Nowadays, there is a high demand for great structural implementation and multifunctionality with excellent mechanical properties. The porous structures reinforced by graphene platelets (GPLs) having valuable properties, such as heat resistance, lightweight, and excellent energy absorption, have been considerably used in different engineering implementations. However, stiffness of porous structures reduces significantly, due to the internal cavities, by adding GPLs into porous medium, effective mechanical properties of the porous structure considerably enhance. This paper is relating to vibration analysis of fluidconveying cantilever porous graphene platelet reinforced (GPLR) pipe with fractional viscoelastic model resting on foundations. A dynamical model of cantilever porous GPLR pipes conveying fluid and resting on a foundation is proposed, and the vibration, natural frequencies and primary resonant of such a system are explored. The pipe body is considered to be composed of GPLR viscoelastic polymeric pipe with porosity in which Halpin-Tsai scheme in conjunction with the fractional viscoelastic model is used to govern the construction relation of nanocomposite pipe. Three different porosity distributions through the pipe thickness are introduced. The harmonic concentrated force is also applied to the pipe and the excitation frequency is close to the first natural frequency. The governing equation for transverse motions of the pipe is derived by the Hamilton principle and then discretized by the Galerkin procedure. In order to obtain the frequency-response equation, the differential equation is solved with the assumption of small displacement, damping coefficient, and excitation amplitude by the multiple scale method. A parametric sensitivity analysis is carried out to reveal the influence of different parameters, such as nanocomposite pipe properties, fluid velocity and nonlinear viscoelastic foundation coefficients, on the primary resonance and linear natural frequency. Results indicate that the GPLs weight fraction porosity coefficient, fractional derivative order and the retardation time have substantial influences on the dynamic response of the system.

With decreasing the number of high school graduates, it is vital for each college to maintain its enrollment number as well as to preserve its dropout rate in a lower level. It is true that all universities and colleges have experienced inevitable dropouts that were in fact more serious in 2 to 3-year colleges. There have been prior studies to examine what factors affected to students' dropout in various ways. However, no specific programs were employed to mitigate the rates of dropout. In this study, new encouraging program is introduced for the students who were not ready to study and isolated from classroom. The result showed that the program led to the GPA enhancement in larger number of participants. Nevertheless, the sustainablity of the program would be unclear unless it combines with other existing programs.
