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.

Essay-writing, first introduced to Korean university entrance exams in 1994, is gaining its weight year by year. Especially from 1997 when Nationwide Education Reform System begins, it will be a key component of student selection criteria at Korean universities. Essay-writing's future, however, will not be that smooth unless it shows necessary validity and reliability. This study is on reliability of Essay-writing scoring, mainly from the experience of University K case. To secure solid reliability in Essay-writing scoring for the 1995 University Entrance Exam, the authors started research from the 1994 Autumn Pre-exam which was administred to potential applicants of University K following year. Total of 1,254 students took Essay-writing exam and, subsequently, their essays were graded by two professors independently. The result was not so good. The correlation between two scores was 0.27[0.54] with Cronbach alpha 0.43[0.70] for Humanity-Social Science [Natural Science-Engineering] field. So, some action for reliability improvement was inevitable. The authors considered and investigated following two alternatives. Alternative 1 [A1] : Essays are to be graded three tiems independently at the 1995 University K Entrance Exam. Scores will be given as the average of three scores. Alternative 2 [A2] : Essays are to be graded twice independently, followed by a possible third grading only if two gradings show "significant" defference. Scores are given as the third score if done or the average of first two scores otherwise.otherwise.

This study aimed to propose a methodology for quantitatively analyzing problems resulting from the performance and combination of the ionization chamber when using an automatic exposure control (AEC) and to optimize the performance of the digital radiography (DR). In the experimental method, the X-ray quality of the parameters used for the examination of the abdomen and pelvis was evaluated by percentage average error (PAE) and half value layer (HVL). Then, the stability of the radiation output and the image quality were analyzed by calculating the entrance surface dose (ESD) and entropy when the three ionization chambers were combined. As a result, all of the X-ray quality of the digital radiography used in the experiment showed a percentage average error and a half value layer in the normal range. The entrance surface dose increased in proportion to the combination of chambers, and entropy increased in proportion to the combination of ionization chambers except when three chambers were combined. In conclusion, analysis using entrance surface dose and entropy was found to be a useful method for evaluating the performance and combination problems of the ionization chamber, and the optimal performance of the digital radiography can be maintained when two or less ionization chambers are combined.

By accessing the current status of FPD system use in the hospitals located in Seoul and Gyeonggi Province as well as the entrance skin dose and the image quality evaluation realized by C-D Phantom, and the image assessment by the medical professionals regarding the radiography for the extremity, the following results were derived. 1. According to the evaluation made in the actual use of FPD system (12 machines), the grid ratio varied from 8:1 to 13:1, and 6 machines used the grid ratio with 12:1, realizing the largest number. Among the machines, there were 8 machines that allowed a removable grid while 3 machines did use a removable grid (25.0%). 2. When it came to the equipments used for the experiment, it showed that the amount of the entrance skin dose increased from 4.13 times up to 4.79 times with the grid use. 3. The difference in the entrance skin dose depending on the changes in the exposure condition(0.5times or 2.0times) was not significantly different regardless of the patients' thickness. 4. In terms of the image quality depending on C-D Phantom, the grid use was distinguished well. However, the images were well distinguishable as the exposure condition got increased. 5. In the clinical assessment, the grid use was less effective for the Hand PA, which was considered to shoot a thin body part. It was evaluated that the grid use was preferred for the Knee AP, which was shooting for a relatively thick body part. Nonetheless, 3 out of 5 people said that they would not use the grid if the entrance skin dose to reduced.

Although the number of users of urban railways is greatly influenced by the land use plan around the railway station, Korea has been studying this problem in a small scale, so that the entrance width is uniformly calculated irrespective of the land use plan, And there is little deviation. Therefore, this study aims to establish a demand estimation model for the entrance and exit of urban railway stations. For this purpose, the demand, land use area, and socioeconomic indicators for each of the 20 urban railway stations were surveyed at 200m and 500m Regression model. The model is based on the assumption that the dependent variable (response variable) of the model is set to 1 day, peak 1 hour, peak time 5 minutes, Education, and park) and socioeconomic indicators (population, employer, employee, and student) as independent variables (explanatory variables). As a result, it was analyzed that the fit of the model is more statistically significant when the use area of the land use by 500 meters of the center radius of the city rail is used as an independent variable and the demand for the daily use of the railway station is used as a dependent variable. The purpose of this study is to estimate the optimal size of urban railway entrance in order to improve the mobility of the user and the transportation weak in urban railway station.

Background: The purpose of this study is to investigate the effects of entrance exam stress on oral health behaviors and subjective oral health status in female high school students. Methods: A self-reported questionnaire was administered to 216 female high school students in the Gwangju area. We performed an independent t-test, one-way analysis of variance (ANOVA), Pearson's correlation coefficient, and multiple regression analysis using the SPSS/WIN 21.0 program. Results: The average of the entrance exam stress was 2.73, and among the sub-areas, the tension for exam/poor stress was the highest with 3.21. As a result of analysis of general characteristics and subjective oral health status, oral mucosal disease was lower in family income level (p<0.05), bad breath was significantly higher with lower academic performance (p<0.001) and family income level (p<0.05). As a result of oral health behavior and subjective oral health status analysis, dental caries has more than 4 times of caries snacks (per week) (p<0.05), bad breath was found to be more perceived when the average number of daily brushing was 2 or less (p<0.01). Factors affecting subjective oral health status were that dental caries was a patients pressure stress (β=0.202); temporomandibular disorder (β=0.227), xerostomia (β=0.342), and oral mucosal disease (β=0.190) were insufficient spare time; bad breath was academic performance (lower) (β=0.231) and insufficient spare time (β=0.184). There was a statistically significant positive correlation between the subjective oral health status and the subarea of entrance exam stress, excluding future uncertainty stress. Conclusion: It is considered that oral health education should be conducted to prevent oral diseases for students with high parental pressure and insufficient spare time stress as well as finding practical ways to reduce entrance stress.

The purpose of this study was to explore the meaning of early entrance experiences of science gifted high school students. The subjects were 13 students who are attending science gifted high school in Seoul. The research data were collected through in-depth interviews. The qualitative study applied the phenomenological method of Giorgi. The early entrance experiences of science gifted high school students were clustered into 13 specific themes and 5 general structures. The results indicated that the early entrance students were surprised by their admissions from the school and they worry about their lack of readiness. However, they follow up their missed 1 year study after all. It took from a few weeks to 1~2 years depending on the student. At any rate, the environment of the school such as differentiated curricular, dormitory life, and studying atmospheres were helpful for the students to adopt easily. Even though they sometimes show a little deficiency, it won't be an issue, they just corporate each other and pursue their studies. As time goes on, they become friends even though they call other students 'big brother'. When the placement of gifted students take place, we do not need to hesitate because of their age, but need to consider the environment of school and characteristics of student.

This study is a descriptive survey on the studying science subjects before entrance to nursing department, the scores of basic nursing sciences and the academic adjustment. The data were analyzed using SPSS 19.0. There was a significant difference between studying certain science subjects before entrance and the scores of basic nursing sciences, studying Biology I, Chemistry I, Physics I and Earth science I increased mean score of basic nursing sciences(p<.05), there were positive correlations among them. And there was no correlation between studying science subjects before entrance and academic adjustment except Physics I, but, there was a positive correlation between score of basic nursing sciences and academic adjustment(r=0.296, p<.001). Also, studying science subjects before entrance affected partially to the scores of basic nursing sciences, and the scores of basic nursing sciences affected academic adjustment(p=.001). This result can be used in pre-school program for the freshmen after repeated study.
