This study has an objective to analyze the causal relationship between the business resource of the members in the Airport Special Guard's firms and its effect on their business attitude and turnover intention. To carry out the study, I established a population of Airport Special Guard's working at the Airport firms in In-cheon, Kim-po, Cheong-ju and Dae-gu. Then a total of 300 questionnaires were sent out for the survey using the random sampling method of clusters. The study was carried out over about four months, from July, 2016 to october, 2016. A total of 260 questionnaires were used for the final data. 40 questionnaires were excluded either because they were not returned or contained extreme value. In this study, a statistical package of SPSS WIN 18.0 were used in the data analysis and the causal relationship was verified using the multiple regression analysis. The analysis showed the business resource to have a positive effect on the business attitude but a negative effect statistical level of p<.01 on the turnover intention at the statistical level of p<.001 and the hypothesis was adopted. The hypothesis regarding the business attitude was also adopted because business attitude was found to have a negative effect on the turnover intention at the statistical level of p<.01. In addition, business attitude was found to have a negative effect on the relationship between the business resource and turnover intention at the statistical level of p<.05. As a result, the hypothesis about the business attitude would function as the parameter was only partially adopted. Through these research result, it was investigated that the relation between business resource, business attitude and turnover intention is significantly effective variable in airport special guard's. Additionally, business resource is the most important.

Objective: The long interspersed elements (LINE-1, L1s) are a group of genetic elements found in large numbers in the human genome that can translate into phenotype by controlling genes. Growing evidence supports the role of epigenetic in polycystic ovary syndrome (PCOS). The purpose of this study is to evaluate the DNA methylation levels in LINE-1 in a tissue-specific manner using cumulus cells from patients with PCOS compared with normal controls. Methods: The study included 19 patients with PCOS and 22 control patients who were undergoing controlled ovarian hyperstimulation. After oocyte retrieval, cumulus cells were extracted. LINE-1 DNA methylation levels were analysed by bisulfite treatment, polymerase chain reaction, and restriction enzyme digestion. The Connection Up- and Down-Regulation Expression Analysis of Microarrays software package was used to compare the gene regulatory functions of intragenic LINE-1. Results: The results showed higher LINE-1 DNA methylation levels in the cumulus cells of mature oocytes in PCOS patients, 79.14 (${\pm}2.66$) vs. 75.40 (${\pm}4.92$); p=0.004, but no difference in the methylation of cumulus cells in immature oocytes between PCOS and control patients, 70.33 (${\pm}4.79$) vs. 67.79 (${\pm}5.17$); p=0.155. However, LINE-1 DNA methylation levels were found to be higher in the cumulus cells of mature oocytes than in those of immature oocytes in both PCOS and control patients. Conclusion: These findings suggest that the epigenetic modification of LINE-1 DNA may play a role in regulating multiple gene expression that affects the pathophysiology and development of mature oocytes in PCOS.

The objectives of this study were to evaluate the gap between perceived importance and performance of foreign Chinese students' off-campus restaurants selection attributes and to analyze the factors affecting their satisfaction with off-campus restaurants. All statistical analyses were conducted using the SPSS package program (ver. 20.0). In summary, Importance-Performance Analysis results indicated that 'price propriety', 'ventilation of dining room' and 'friendliness of employees' were key aspects that should be reinforced by off-campus restaurant managers. Additionally, exploratory factor analysis on the validity of the 23 attributes of off-campus restaurant selection resulted in the identification of 5 factors including 'food quality and price', 'physical environment and value', 'service environment', 'service quality', and 'convenience and cleanness'. According to the results of multiple regression analysis, 'service quality', 'service environment', 'food quality and price', and 'physical environment and value' had significantly positive effects on overall satisfaction. In conclusion, in order to increase customer satisfaction among Chinese students, off-campus restaurant managers should improve not only the quality of service and food, but also the physical and service environment.

Purpose : The present study attempted to consider the degree of consciousness of economic ethics in nursing students and the factors affecting these perceptions. Method : A survey was conducted to a total of 874 nursing students from the freshmen and seniors of 11 depts of nursing science nationwide selected by convenience sampling (one for each province, and as for Gangwon-do, two schools were selected from Yeongdong area and Yeongseo area ; 13 male students were excluded). A structured questionnaire was used to collect data on their demographic characteristics and economic ethical perceptions. Collected data were analyzed using the SAS V8.1 statistical package. Result : (1) The score for the economic ethical consciousness of the subjects was $36.76{\pm}10.20$. As for each sub-categories, the score for industry was $7.67{\pm}2.77$; thrift, $7.42{\pm}2.37$; cooperation, $7.41{\pm}2.21$; occupational consciousness, $7.18{\pm}2.20$; and, for consumption, $7.02{\pm}1.90$. The score for the consciousness of consumption was the lowest. (2) Among the demographic characteristics of the subjects, age was found to have a statistically significant positive relation to the consciousness of economic ethics(r=.13, p<.001). The next significant factor was grade: seniors seemed to have a higher economic consciousness in all the sub-categories than freshmen(t=-4.32, p<.001). The number of in-home family has a statistically significant negative correlation with economic attitudes(r=-.15, p<.001). In addition, their economic ethical perceptions were significantly higher with no religion (t=2.14, p<.05); have an unemployed father (t=2.78, p<.05); have credit cards under their own names (t=3.04, p<.05); have ever had overdue card bills (t=4.25, p<.001); have ever had part time job(t=1.74, p<.1) and when they don't live with their parents (t=-2.01, p<.05). 3) A multiple regression analysis was conducted to examine the influential power of the factors affecting the consciousness of economic ethics of the subjects. The factors had more influence on the economic attitudes of the seniors than those of freshmen; in those who having credit cards under their own names than under others; and, in those who have ever experienced credit default than those haven't. Though these factors raised average 3.0 points of economic consciousness, their expository power for the consciousness were low. Conclusion : The nursing students had medium-high consciousness of economic ethics and they seemed to have low consciousness of the proper consumption practices. Their actual life experiences had an influence on their economic attitudes. Therefore, practical programs on economic knowledge should be developed and taught to students systematically at school so that they could have sound consciousness of economic ethics and appropriate knowledge closely related with their real life.

Accidents involving children are an important cause of death and disability. They also have enomorous financial implications. In order to prevent childhood accidents, research and education for safety should be strengthened. The purpose of this study was to determine how often young children have accidents and what factors affect the accident rate. The sample consisted of 771 children who were in the second, third and forth grades of two elementary schools located in Kyung-gi Province. One school had students from middle class families living in apartment complexes and the other, students from lower income families mainly living in single houses. The questionnaires included items on the occurance of accidents and the parents' attitudes regarding accidents during the academic year from March 1997 to February 1998. The Questionnaires were distributed to conventiently selected students to be compeleted by their parents and collected during the period of May 28, to June 6, 1998. The data were analyzed using SAS PC statistical package. The results of the study are as follows ; 1. Of 771 student subjects, 393 had 887 accidental injuries during the study period. 2. The month, the day and the time with the highest accident rate were May, Sunday, and between 1 and 4 p. m. each. 3. In the analysis of the location where the injury took place, the most frequent place was on around their homes followed by school and, then, inside the home 4. Most of the accidents were caused by carelessness on the part of the children and the most frequent type of injury was an abrasion. 5. Children most injured their legs 6. They were treated at home most often and usually emergency treatment was performed by family members with, disinfection being the main type of first aid. Cost of the treatment ranged from 8,000 to 20,000 won in most cases. 7. House type and parents' education level were statistically significant in chi-square analysis. 8. Parents educate their children about traffic safety most frequently followed by fire safety and, then, prevention of violence. 9. Parents think that prevention of violence should be the most important part of injury prevention education both at school and home. 10. To identify factors related to accident occurrence, multiple logistic regression was performed and the main factors were birth order and house type.

Purpose : To investigate the effects of various intracranial volume (ICV) measurement methods on the sensitivity of hippocampal volumetry and modulated voxel-based morphometry (mVBM) in female patients with major depressive disorder (MDD). Materials and Methods : T1 magnetic resonance imaging (MRI) data for 41 female subjects (21 MDD patients, 20 normal subjects) were analyzed. Hippocampal volumes were measured manually, and ICV was measured manually and automatically using the FreeSurfer package. Gray and white matter volumes were measured separately. Results : Manual ICV normalization provided the greatest sensitivity in hippocampal volumetry and mVBM, followed by FreeSurfer ICV, GWMV, and GMV. Manual and FreeSurfer ICVs were similar in normal subjects (p = 0.696), but distinct in MDD patients (p = 0.000002). Manual ICV-corrected total gray matter volume (p = 0.0015) and Manual ICV-corrected bilateral hippocampal volumes (right, p = 0.014; left, p = 0.004) were decreased significantly in MDD patients, but the differences of hippocampal volumes corrected by FreeSurfer ICV, GWMV, or GMV were not significant between two groups (p > 0.05). Only manual ICV-corrected mVBM analysis was significant after correction for multiple comparisons. Conclusion : The method of ICV measurement greatly affects the sensitivity of hippocampal volumetry and mVBM. Manual ICV normalization showed the ability to detect differences between women with and without MDD for both methods.
