Purpose: In the study, the change of protein and lipid deposits on soft contact lens by drinking was investigated. Methods: Fifty male subjects wearing soft contact lens were surveyed whether they felt any discomfort induced by drinking or not. Further, 32 male subjects who has no ocular disease drank 190 mL alcohol. The protein and lipid deposits on soft contact lens (etafilcon A material) of subjects were measured after 4 hours later and compared with those of non-drinking subject. Results: When subjects drink alcohol with soft contact lens on, 58% of subjects answered they experienced the change of lens awareness such as stiffness, blurry sight, dryness and so on. The protein deposit on soft contact lens increased an average of $59.3{\mu}g/lens$ by drinking and the case of more than double in protein deposit was reached in 9 eyes. However, the protein deposited on soft contact lens was lysozyme which was unchanged by drinking. The amounts of cholesterol and methyl oleate after drinking were 85.5% (p=0.25) and 52.6% (p=0.002) of non-drinking's indicating some change of lipid deposit on soft contact lens by drinking. Conclusions: The results showed the composition of protein and lipid deposited on soft contact lens was changed due to drinking. Thus, it is suggested that wearing soft contact lens when drinking might be one of the reasons to feel discomfort.

Phytoestrogens are biologically active compounds derived from plants foods. It had been suggested that phytoestrogens, by inhibiting aromatase in peripheral and/or cancer cells and lowering estrogen levels, may play a protective role as antipromotional compounds during growth of estrogen-dependent cancers. Therefore, simultaneous analysis of estrogens and phytoestrogens is necessary to elucidate the possible involvement of phytoestrogens in estrogen metabolism. In this view, we developed a simple and reproducible procedure to quantitatively determine estrogen and phytoestrogen metabolites. The proposed method consisted of solid phase extraction using preconditioned Serdolit AD-2 resin, enzyme hydrolysis with ${\beta}$-glucuronidase/arylsulfatase from Helix pomatia, liquid-liquid extraction and TMS-ether derivatization. And the final determination was carried out by gas chromatography/mass spectrometry (GC/MS) in selected ion monitoring mode (SIM). The precision and accuracy of this method was evaluated through within-a-day and day-to-day test. Recovery range and detection limit were 71.96~105.66%, 2~4 ng/mL, respectively. Using this method, 17 estrogen and 5 phytoestrogen compositions in urine of normal subjects were analyzed. It was found that amounts and relative distribution of urinary phytoestrigens and estrogens showed different pattern in male and female subjects.

The purpose of this study was to investigate difference between grip strength, upper limb dexterity, and hand function according to touch and heat sensory stimulus. Forty healthy men were recruited. After obtaining subjects characteristics, examined grip strength, upper limb dexterity, and hand function, then we made touch sensory input using soft brush and tried the test again. Next day, we made thermal input using hot pack and did retest, too. The result showed significant differences appeared on every variable in grip strength and upper limb dexterity test (p<.001), and significant differences appeared on every variable except lifting small objects in hand function (p<.01). In conclusion, sensory input is to increase grip strength, upper limb dexterity, and hand function. The thermal sensory input has a tendency to increase grip strength, upper limb dexterity, and hand function than that of touch sensory input in effect of stimulus classification. The application of proper stimulus helps to facilitate upper limb and hand function in rehabilitation and in industrial field. So it is necessary to try more tests of frequency and intensity of stimulus.

Since it is imperative to share the values with the spectators to convince the public of the era, the main characters of a story that underwent numerous adaptation through time would change gradually. This paper examined changes of the main characters in various versions of Cinderella. Until the mid-20th century, Cinderella would be portrayed as a meek, passive and obedient girl as in the original fairy tale version of Perrault. As moving to 70s, a heroine who acts with her own feelings and thoughts began to appear. In the 90s, spectators could meet a protagonist who fought fiercely to be the owner of her own fate, and in the recent Disney movie, Cinderella stood up for herself while accepting herself as she was. The prince character also underwent similar transition. In the early versions of Cinderella, the prince would be a vague figure with a title who was desired by all maids in the country. It is in the 70s that the prince began to be portrayed as a person who has his own problems. In the recent years, the spectators could see the process that the prince transformed from a naive aristocrat to a man with responsibilities. In modern society, women have more social opportunities compared to the past, and women's social statuses do not need to be secured by relationship with men any longer. Thus Cinderella story is not as popular nowadays, moreover somebody whose dream is becoming Cinderella would subject to social reproach. However, beside the gender, the story could be the only hope for people who feel a sense of helplessness that there is no chance in their lives. As result variations of Cinderella story will go on as long as people of social deprivation exist.

The low birth rate in South Korea is a very serious problem. Recently, as personal happiness has emerged as an important life value of life, unmarried people have developed a negative tendency toward marriage. This study was conducted to investigate the attitude toward marriage, gender role and having children among college students, and to identify the factors affecting marriage. The participants were 383 unmarried nursing college students who live in D city. Data were collected from self-report questionnaires and analyzed using the t-test, one-way ANOVA, Pearson's correlation coefficients, and stepwise multiple regression using the SPSS 22.0 program. Gender was a significant variable influencing attitude toward marriage. Moreover, the attitude toward marriage was negatively correlated with gender role, and positively correlated with having children. Attitude toward gender role was negatively correlated with having children. Regression analysis of the factors affecting attitude toward marriage showed that gender (male), attitude toward gender role, and attitude toward having children were significant influencing factors. Moreover, this model explained 51.9% of variance in attitude toward marriage. Overall, it is necessary to change individual values to solve the problem of low birthrate.

Objectives: Metabolic syndrome and depression are interconnected disorders. Although many studies have assessed the association between dietary intake and each disorder independently, few studies have examined the association between depression and dietary intake in patients with metabolic syndrome. Our study examined the association between depression and dietary intake in adults with metabolic syndrome. Methods: We analyzed the second data set (2014) from the sixth KNHNES. Of the patients with metabolic syndrome, the final study population comprised 1,334 patients, aged 20 to 60 years, with metabolic syndrome as defined by KNHNES and depression diagnosed by a physician. We examined the patients' dietary intake obtained using the 24-h recollection method in KNHNES. Results: Depression group had a lower niacin dietary intake than those without depression in both male and female (male P=0.047, female P=0.025). None of the other components had any association between depression group and those without depression group in both male and female. Conclusions: This study demonstrates that a low dietary intake of niacin may be related to the depression in patients with metabolic syndrome. The results indicate that it is worthwhile to evaluate the nutritional status in patients who have been diagnosed with both metabolic syndrome and depression.

Though adolescents have the skillful ability to use internet and use it extensively, they have experienced sexually less than adults and are hard to have the right viewpoint toward sexuality. Because of these adolescents' characteristics, internet pornography cause them serious troubles with their sexual behavior. Based on the viewpoint, this research explores structural relationship among their sexual orientations, exposure to internet pornography, the sexual drive and behavior with PLS path modeling analysis. In result, androcentric and pornography-friendly sexual orientation have an influence on the exposure to internet pornography, in turn, the exposure to internet pornography affect the sexual drive and behavior directly and sexual behavior indirectly mediated by the drive. The significance of this research is to identify fact that sexual orientations, reconceptionalized from previous researches's dependent variables, predict the exposure to internet pro-pornographic and is to identify a popular myth indirectly that the exposure to internet pornography stimulates sexual drive to cause behavior, in turn leads to sex crimes finally.

Sella turcica contains pituitary gland that has influence on craniofacial growth. So, if the volume of sella turcica correlate to the function of Pituitary gland, we can assume that the volume of sella turcica in skeletal Class III patients has some difference to that of normal occlusion group. The purpose of this study was to evaluate the difference of shape and volume of sella turcica between normal occlusion group and Class III patients. The shape of sella turcica was Classified by Inaba method and the volume of sella turcica was measured in lateral and P-A cephalograms by Di Chiro method. To find out the possibility of the volume of sella turcica as diagnostic aid to predict Class III growth pattern, the correlation coefficients between the volume of sella and cephalometric variables were calculated. The results were as follows. 1. The volume of sella turcica in Class III patients is larger than that of normal occlusion groups 2. The volume of sella turcica in female was larger than that of male in Class III patients 3. The volume of sella turcica has close correlation with APDI, ANB, SNA, SNB, ODI, gonial angle, post. cranial base length 4. Sella Index (volume of sella / ant. cranial base length) can be a more accurate indicator that represent Class III growth pattern than volume of sella itself. 5. The morphologic pattern of sella turcica had no significant difference between two groups.

Background: Many studies focus on the causes of depression, but few assess the dietary intake. This study investigated the relationship between diet and prevalence of depression. Methods: This study used the data from the Korea National Health and Nutrition Examination Survey 2010. A total of 734 persons aged 20-65 years old in whom the presence or absence of depression was confirmed by doctor were analyzed. We analyzed associations between prevalence of depression and diet based on carbohydrate, fiber, calcium, iron, sodium, potassium, vitamin A, thiamine, riboflavin, niacin and vitamin C intakes for male and female groups. Results: There was no association between diet and prevalence of depression in the male group. For the female group, as fiber intake was increased, the prevalence of depression significantly decreased (odds ratio=0.923, 95% confidence interval=0.850-0.986), but there was no association between the other dietary intakes and prevalence of depression. Conclusion: The fiber intake and prevalence of depression are negatively correlated in women aged 20-65 years. A diet therapy including fiber may decrease the prevalence of depression.

The main purpose of this study is to investigate the important impacting factors of health-related quality of life (HRQOL) by different age groups. The subjects of this study were 5,976 adults over 19 based on data from the 2014 Korea National Health and Nutrition Examination Survey and EQ-5D index score was used for the measurement of HRQOL. Three age groups were considered of young (19-39), middle (40-65), and old (over 66) and for each age group Bayesian ordered probit model analysis was fitted to identify significant factors and their effects on HRQOL. Sex, subjective awareness of health, stress and diseases have been identified to be common important factors for all age groups. HRQOL of women is more likely to be lower than that of men. Subjective awareness of health affect positively but stress and diseases affect negatively on HRQOL. For middle age group, occupational activities have been found to be important positive factors on HRQOL. On the other hand, obesity is more important factor influencing on HRQOL negatively and frequent walking is recommended for old age group.
