In this study we examined the preferences of eight college living factors for students at Korea National College of Agriculture and Fisheries(KNCAF). Analytical techniques of unstructured data used opinion mining and text mining techniques, and the analysis results of text mining were visualized as word cloud. The college life factors included eight topics that were closely related to students: 'my present', 'my 10 years later', 'friendship', 'college festival', 'student restaurant', 'college dormitory', 'KNCAF', and 'long-term field practice'. In the text submitted by the students, we have established a dictionary of positive words and negative words to evaluate the preference by classifying the emotions of positive and negative. As a result, KNCAF students showed more than 85% positive emotions about the theme of 'student restaurant' and 'friendship'. But students' positive feelings about 'long-term field practice' and 'college dormitory' showed the lowest satisfaction rate of not exceeding 60%. The rest of the topics showed satisfaction of 69.3~74.2%. The gender differences showed that the positive emotions of male students were high in the topics of 'my present', 'my 10 years later', 'friendship', 'college dormitory' and 'long-term field practice'. And those of female were high in 'college festival', 'student restaurant' and 'KNCAF'. In addition, using text mining technique, the main words of positive and negative words were extracted, and word cloud was created to visualize the results.

Purpose: For minimally invasive procedures, three-dimensional (3D) anatomical knowledge of the structures of the face is essential. This study aimed to describe the thickness of the skin and subcutaneous tissue and depths of the facial muscles located in the infraorbital region using a 3D scanner to provide critical clinical anatomical guidelines for improving minimally invasive cosmetic procedures. Materials and Methods: The 3D scanning images of 38 Korean cadavers (22 males and 16 females; age range: 51~94 years at the time of death) were analyzed. Eight facial landmarks (P1~P8) were marked on the cadaveric faces. The images were scanned in three steps-undissected face, hemiface after skinning, and revealing the facial muscles. Student's t-test was used to identify significant differences. Result: The skin and subcutaneous tissue tended to become thicker from the upper to lower and medial to lateral aspects, and the muscles followed the same pattern as that of the most superficial located muscle and the deepest located muscles. No significant sex-related differences were found in the skin at any landmark. However, the muscles tended to be deeper in the female participants. Conclusion: The study data can serve as a basis for creating or enhancing clinical anatomy-based guidelines or improving procedures in the infraorbital region.

This study aims to grasp the influence of a college student's academic emotions and the ability of interpersonal relations according to gender on the SNS addiction tendency. Data were collected through a self-reported structured questionnaire from 130 college students using convenient sampling methods from September 1 to October 31, 2015. The research result showed that in the case of male college students, only the ability of interpersonal relations (${\beta}=-.41$, p=.009) was understood as a variable with an influence on the SNS addiction tendency, having approximately 16% power of explanation (F=2.26, p=.049) after controlling for age, daily average duration of using SNS, subjectively-perceived level of dependence on SNS, and one's own level of using SNS. In the case of female college students, it was understood that the daily average duration of using SNS (${\beta}=.42$, p<.001) and positive academic emotions(${\beta}=.27$, p=.010) were variables having an influence on the SNS addiction tendency, having approximately 28% power of explanation (F=5.19, p<.001). Accordingly, to solve the psycho-social health problems related to male and female students' SNS addiction based on this research, it might be helpful for planning a program by taking into account the differences between the related variables according to gender.

The purpose of this stud was to investigate the degree of recognition as well as the consumption pattern of convenience food products, and related factors among 700 mixed Korean college students using written questionnaire. Students of Seoul region showed the significantly lowest rate of recognition at 36.7%. Results also showed that lifestyles have a significant effect on the degree of recognition of convenience foods. The consumption patterns of convenience foods goes as follows: used frequently-18.2%, once in awhile-73.9%, doesn't use-7.9%. The higher the recognition rate, the higher the consumption rate for convenience foods. When compared in terms of residence, students living at home used more refrigerated foods compared to students living outside of the home. Among the total students living outside of the home, students living on their own scored highest of convenience food consumption. In the case of female students living outside the home, respondents living alone and in dormitories scored the highest. Female students living in dormitories were mainly using refrigerated and canned foods, while those living alone consumed more kimbap and 'sa-bal-myun' in convenience stores. Korean college students mainly consumed frozen food, retort food, and kimbap in convenience stores. The college student that believes that 'You eat to satisfy hunger' significantly used more convenience food while those that marked 'maintain health' consumed the lowest showing a great difference between groups. Results showed that the lower the food habit score, the higher the usage score of convenience foods. The food habit score had a negative correlation with the usage of frozen foods, instant food, and convenience store food. When compared individually, packaged 'ramen' and 'sa-bal-myun' scored the highest points of usage. Frozen fried rice and pre-packaged rice scored the lowest points indicating Korean college students do not consider rice a convenience food. Convenience food consumed in convenience stores ranked the highest among places of consumption, compared to places like home or outdoors; showing that convenience foods were used by people with limited time constraints.

Background:The dopaminergic genes have been implicated with some personality traits. Many recent studies indicated that there is a correlation between D2 dopamine receptor gene(DRD2) polymorphisms and the personality traits. The purpose of this study is to investigate a possible association between DRD2 gene (TaqI A, TaqI B) polymorphism and personality traits. Methods:The subjects were consisted of 173 blood-unrelated young female Koreans with a mean age(${\pm}SD$) of 13.88(${\pm}0.29$) years. These volunteers were recruited from one of the junior high schools in Seoul and were tested by the Korean version of the Temperament and Character Inventory(TCI). Genotyping of the DRD2 polymorphisms by PCR methods were carried out. Two DRD2 gene polymorphisms were classified and individually assessed as follows:TaqI A1+ vs A1-, TaqI B1+ vs B-. The associations between the TCI scores and TaqI A, TaqI B polymorphisms were assessed by Student's t-test. Results:In the 173 subjects, the allele frequencies of the DRD2 TaqI A1, TaqI B1 alleles ranged from 0.42 to 0.43, and these results are quite different from the ranges of 0.15-0.20 in the case of a Caucasian population. The genotype frequencies of DRD2(TaqI A1, TaqI B1) variants showed no significant deviation from the Hardy-Weinberg equilibrium. RD4(dependence vs. independence) of Cloninger's TCI, a sub-dimension of Reward Dependence, was significantly higher in the subjects having DRD2 less frequent alleles than those without these alleles. Conclusion:This study suggests that the female subjects carrying the less frequent DRD2 alleles exhibited higher reward-dependent personality trait compared to those without these alleles.
