Current mathematics of CSAT(College Scholastic Ability Test) faces time to prepare examination questions according to the new curriculum making this year the last. MEST(Minister of Education, Science and Technology) already decided the range of examination in 2008. However, the discuss about how to construct the questions and what form of questions should be set was not conducted enough. Mathematics items of CSAT will have to undergo changes both in 2012 and 2014. Also, reconstruction of the examination questions for the past 16 years and the exploration of the new direction are strongly required. To accord with these requirements, this study analyze Japan's college entrance exam, NCTUA(National Center Test for University Admissions) which is the most similar to our exams. And then on the basis of this, the applicable implication to set mathematics questions in 2012 and 2014 CSAT will be deducted.

Purpose: This study was done to examine the frequency of irritable bowel syndrome (IBS), entrance examination stress, mental health, and quality of life among adolescent women. Methods: A survey conducted to collect data from 925 adolescent women in Gyeonggi Province. The measurements included the Rome III criteria (to diagnose IBS), the entrance examination stress scale (to evaluate stress), symptom check list90R (SCL-90R to evaluate mental health), and World Health Organization Quality of Life Abbreviated Version (WHOQOL-BREF to evaluate quality of life). Frequency, $X^2$-tests, t-test, and analysis of variance (ANOVA) with the SPSS 16.0 program were used to analyze the data. Results: The frequency of IBS in the women was 22.8%. One hundred thirty eight women (65.4%) had the mixed constipation and diarrhea subtype of IBS. Compared to the women without IBS, those with IBS reported significantly higher scores on entrance examination stress scale, SCL-90R, all subscales of SCL-90R, and lower scores on WOLQOL-BREF. Conclusion: Nursing interventions targeting adolescent women with IBS should be developed in order to alleviate the associated stress and mental health and to promote quality of life.

The microchannel flow in miniature TCDs (thermal conductivity detectors) is investigated numerically. The solutions based on the boundary layer approximation are not very accurate in the region of the duct inlet for low Reynolds numbers. In this study, two-dimensional Navier-Stokes equations are considered to analyze the gas flow in a miniature TCD. Effects of channel size, inlet and boundary conditions on the heat transfer rate are examined. When the gas stream is not preheated, the distances for a miniature TCD to reach the conduction-dominant region for duct flow are found to be approximately two and three times the thermal entry length for duct flow with constant properties, respectively, leer constant wall temperature and constant wall heat flux boundary conditions. If the gas temperature at the channel inlet is close to the mean gas temperature in the conduction-dominant region, the entrance region is much shorter compared to other cases considered in this study.

Objectives : This paper aims to examine the meaning of guanjie(關節) in the Huangdineijing. Methods : Meanings of guan(關) and jie(節) were examined within the Neijing, after which the meaning of guanjie was studied in reference to usages of guan and jie. Other terms used similarly to guanjie were also studied. Results & Conclusions : 1. The meaning of guanjie in the Huandineijing could be inferred to meanings such as 'vital point and node', 'node of entrance gate', 'entrance gate and node', 'bolt and node', 'node of bolt', etc. 2. Most usages of guanjie in the Huangdineijing referred to 'pivotal node', while those mentioned in relation to edema or joint pain from wind and dampness meant 'node of entrance gate.' 3. The four entrances, eight nodes, extremity node, eight hollows, eight nodes of the limbs, twelve nodes, which are used similarly to guanjie, manage the five zang, communicate intimately via qi, while shen qi or zhen qi enter and exit. 4. Guanjie is closely linked to the five zang, while it is the entrance gate or pivotal node through which shen qi roams and travels. Therefore when interpreting a verse that includes 'guanjie', one must be aware of the perspectives of the Huangdineijing on qi, keeping in mind the close relationship with the five zang, and that zhen qi enters and exits.

This study is to calculate the exposed radiation dose using Bit method, NDD calculation method and monogram method without dosimeter. In addition, we can calculate the radiation dose from x-ray film density as a film badge. The authors examined the entrance skin dose from $2{\sim}3$ intercostal chest x-ray film density. We also studied the relationship between film density and equivalent dose in the each screen film system under the different radiation quality and the poor geometry condition of grid ratio. As results, we established the deductive method to define the entrance skindose from chest x-ray film density. The error range was found in the range $-13%{\sim}+l7%$ for between deductive entrance skindose and the $2{\sim}3$ intercostal chest x-ray film density to actual detective radiation dose with dosimeter.

Recently, CTI (Computer Telephony Integration) technology has been widely applied to various area such as video conference, file transfer, voice mail, automatic message transfer and automatic redial, integrated messaging and network fax. In this paper, an administrative affairs supporting system using call control mode of CTI is designed. To improve inefficient processing of job due to heavy calling from entrance candidates during entrance examination of a college, the system is developed. The database of the system is desigend using object modeling technique. Also, the automatic calling and response system using CTI call control mode is implemented. Especially, to interface with voice of candidates who ask whether they pass or fail the entrance examination of the college, TTS(Text To Speech) module is developed.

We have presented with the "A study on overexposure rate according to over-density in chest X-ray radiography(I)" last year. In this report, We could calculate the entrance skin dose from chest X-ray film density the formula $I_0=Ix/e^{-{\mu}x}{\times}mG$, (mG is Bucky factor) was used to deliver the skin dose. At that time, There was two problems that the Bucky factor from maker was not equal to field experience and the field size influenced on the Attenuation Rate. The experiment of Bucky factor was done from film method and retried the Attenuation Rate of Acryle phantom according to Good & Poor geometry. As the results, The Bucky factor from maker higher than in this experiments $30{\sim}40%$. The Attenuation Rate in good geometric condition brings about a little alteration compare with poor geometric condition. In the field experiment, we could get the chest image with very low entrance skin radiation dose $29.3{\mu}Sv$, especially with air gap methode, the entrance skin dose was detected $10{\mu}Sv$.

The purpose of this study were to investigate the current problems of family in adolescents' college entrance examination and to propose the practical alternatives about effective overcoming strategies. To study these objectives two kinds of sample and questionnaire were selected and the data were obtained through 360 parent-child pairs and 802 college preparatory institute students living in Seoul Taejon and kwangju. The major findings were as follow: 1. Educational achievements were affected by adolescents' personal traits as achievement need self-regulation emotional stability and self-concept but parents ' over-aspirations were negative agent for stress coping. 2. Parent-adolescent intimate and self-regulated relationships were positive factors for achievement and educational self-concept. Also adolecsents' educational aspirations were more significantly affected by parents' emotional supports. 3. Family stress were mediated by parent-child conflict so satisfied parent-child relationships can protect serious stressors as examination problems. Especially father-related factors were importantly revealed. In conclusion adolescent family and society must develop coping methods individually and cooperatively through family life education systematic policy and educational reformation.
