The nucleotide sequences of a male-specific marker sex determining region Y (SRY) gene and a mitochondrial cytochrome B (CYTB) gene were characterized and analyzed to establish a molecular method for identification of species and sex of Korean roe deer (Capreolus pygargus tianschanicus). Similarity search result of SRY sequences showed very similar result to those reported in Moose (Alces alces) and Reindeer (Rangifer tarandus), both of which had 95.9% similarity in identity. CYTB genes were very similar to those reported in Siberian roe deer (C. pygargus pygargus) which had 98.6% similarity and not to European roe deer (C. capreolus), suggesting that the DNA samples tested were of Siberian roe deer lineage. Polymerase chain reaction (PCR)-based sex typing successfully discriminated between carcasses of male and female roe deer. Males had SRY band on agarose gels and females did not. The result of this molecular sex typing provided similar information with that obtained by genital organ observation. Therefore, this molecular method using male specific marker SRY and mitochondrial CYTB genes would be very useful for identification of the species and sex of the carcass remains of roe deer.

Background: The purpose of this study was to analyze the equality between key words used in the Journal of Korean Dental Society of Anesthesiology and Medical Subject Headings (MeSH). Methods: A total of 666 English key words in 187 papers (average 3.5 words in a paper) from 2001 to 2014 were eligible for this study. We classified them according to matched, and non-matched terms. After descriptive analysis, we assayed patterns of errors in using MeSH, and reviewed frequently used non-MeSH terms. Results: Fifty nine point six percent (59.6%) of total key words were completely coincident with MeSH terms, 40.39% were not MeSH terms. Conclusions: The results show that the coincidence rate of key words with MeSH terms was at a moderate level. However, there is a need for us to understand MeSH more specifically and accurately. Use of proper key words aligned with the international standards such as MeSH is important to be properly cited. The authors should pay attention and be educated on correct use of MeSH as key words.

Objectives: The purpose of the study was to investigate the relationship between internet addiction and health in dental hygiene students. Methods: A self-reported questionnaire was completed by 216 dental hygiene students in Daegu from June 9 to 13, 2014. Data were analyzed by descriptive statistics, t-test, and ANOVA using SAS 9.2 program. The instruments included Korean internet addiction scale(K scale) and Korean version of the general health questionnaire. General characteristics consisted of grade, religion, residential types, economic condition, place of internet use, duration, purpose, and time of use. Physical characteristics consisted of subjective physical condition, smoking, alcohol drinking, exercise above twice per week, musculoskeletal disease, and location of physical symptoms. Psychiatric scale and 6 questions of physical characteristics were consulted by the statistician of preventive medicine department. Results: Internet users over 4 hours manifested the poor mental health, while those who uses internet under 2 hours showed good mental health(F = 1.41, p < 0.01). The students having good physical condition showed better mental health than those with poor physical condition(t = -2.81, p < 0.01). The students exercising at least twice a week showed better mental health than those who do not exercise(t = -3.10, p < 0.01). Those who having musculoskeletal symptoms showed higher index of internet addiction score than those who do not(t = 4.21, p < 0.01). Those who have no musculoskeletal symptoms tended to have better mental health than those who have musculoskeletal symptoms(t = 2.28, p < 0.05). The variables correlated to mental health were internet addiction, subjective physical condition, and exercise at least twice a week. The severity level of internet addiction leads to poor mental health(r = 0.26, p < 0.001). Conclusions: Internet addiction is closely related to mental health. So the students must know the danger of internet addiction. Proper health education is necessary for the prevention of addiction symptoms.

The purposes of this study were to classify university students by their lifestyle and to investigate the relationships between lifestyle and coffee satisfaction. The survey had been undertaken for 360 Korean and Chinese university students in Daejeon from November to December 2009. A total of 242 usable questionnaires were received with 67.2% response rate. The statistical analysis was performed by the SPSS 18.0 package program. Lifestyles of subjects, based on AIO (Activities, Interests, Opinions) method and factor analysis, were segmented into 2 groups of "outgoing activity" (n = 137) and "introverted devotion" (n = 105). "Outgoing activity" group exhibited highly health-oriented (p < 0.001) and convenience-oriented (p < 0.001) characteristics, but "introverted devotion" group showed highly goal-oriented (p < 0.01) and safety-oriented (p < 0.01) features. Comparing to "introverted devotion" group, "outgoing activity" group showed higher intake of coffee (p < 0.01) and more expense for beverage (p < 0.01). Three factors were extracted from 15 coffee quality attributes by factor analysis; "fundamentals", "supplement" and "inducement". These factors were positively correlated with coffee satisfaction according to lifestyle groups (p < 0.01). For "outgoing activity" group, 'fundamentals' was independent factor for satisfaction on coffee in coffee house (${\beta}$ = 0.268, p < 0.05) and canned or bottled coffee (${\beta}$ = 0.314, p < 0.01), and "supplement" was independent factor for satisfaction on coffee in vending machine (${\beta}$ = 0.235, p < 0.05). For "introverted devotion" group, "inducement" was independent factor for satisfaction on coffee in vending machine (${\beta}$ = 0.238, p < 0.001). These results provide an understanding for lifestyles of coffee consumers and give an insight into differentiated marketing plans for coffee industry.

Purpose: The aim of this study is to identify factors of Korean female workers' childbirth plans and to establish measures to improve the childbirth plan. Methods: Study subjects were selected part in the 1st, 3rd, and 5th year surveys of the Korean Longitudinal Panel Survey of Women and Families. The selection criteria were as follows: women who had a spouse; were salaried workers currently employed for the last one month; belonged to a childbearing age; and had less than 3 children. Logistic regression analysis was conducted to investigate factors associated with childbirth plans. Results: Childbirth plans by female workers decreased each year. The analysis of associated factors revealed that age, number of children were associated factors in all years. In addition, education, satisfaction about dividing household chores with the husband, and satisfaction about working environment were associated with the lack of planning for childbirth in female workers in the 1st survey year. Satisfaction about dividing household chores with the husband, family-work conflict, and satisfaction about the potential for personal development were associated factors in the 3rd survey year. Finally, family-work conflict, satisfaction about employment stability, and satisfaction about job task at work were associated factors in the 5th survey year. Conclusion: It is important to know the measures focusing on the lack of planning for childbirth, and hence these factors can be improved by assessing in general, family, and occupational characteristics. Additionally, employer policies regarding women employees who are pregnant or have children at home need to be reviewed.

Research articles were reviewed to validate the estimated energy requirements (EERs) equations developed by the Institute of Medicine of the National Academies (IOM). These equations are based on total energy expenditure (TEE) measured by the doubly labeled water (DLW) method. We subsequently aimed to provide the basis for the suitability to apply the IOM equations as EER equations for Koreans, and develop relevant equations for EER in the Dietary Reference Intake for Koreans (KDRI). Additionally, besides the EER(IOM) equations, other equations were examined for EER estimation. Research papers demonstrating the validation of the EER(IOM) equations based on TEE(DLW) were searched through PubMed (up to September 2019). Of the 637 potentially relevant articles identified, duplicates and unsuitable titles and abstracts were excluded. Furthermore, papers with irrelevant subject and inappropriate study design were also excluded. Finally, 11 papers were included in the review. Among the reviewed papers, 8 papers validated the application of the EER(IOM) equations for EER based on TEE(DLW). These included 3 studies for children (USA 1, Korea 2), 1 for adolescents (Portugal), 2 for adults (Korean), and 2 for the elderly (Korea, USA). EER(IOM) equations were found to be generally acceptable for determining EER by using the DLW method, except for Korean boys at 9-11 yrs (overestimated) and female athletes at 19-24 yrs (underestimated). Additionally, 5 papers include the validation of other EER equations, beside EER(IOM) for EER based on TEE(DLW). In Japanese dietary reference intake and recommended dietary allowance, EER equations are acceptable for determining EER based on TEE(DLW). The EER(IOM) equations is generally acceptable for determining EER using the DLW method in Koreans as well as several populations, although certain defined groups were found to be unfit for the estimation. Additionally, the concept of healthy body mass index of Koreans and physical activity levels need to be considered, thereby providing the basis for developing relevant equations of EER in KDRI.

BACKGROUND/OBJECTIVES: Few studies have provided evidence of the association between diet quality and dental caries. This study aimed to examine the association between diet quality and untreated dental caries in a Korean representative population. SUBJECTS/METHODS: The study population included a sample of 13,815 participants, aged ≥ 19 from the Korea National Health and Nutrition Examination Survey during 2013-2015. The explanatory variable was diet quality and the outcome variable was untreated dental caries. Untreated dental caries were defined by the number of decayed teeth recorded according to the criteria established by the World Health Organization. Diet quality was defined by using the Korean Healthy Eating Index (KHEI) through the 24-h recall methods. We assessed the association between diet quality and untreated dental caries while adjusting for age, sex, education, income, smoking status, dental visits, toothbrushing frequencies, obesity, and diabetes mellitus. RESULTS: The mean overall KHEI scores in the untreated dental caries group were significantly lower than those in the group without untreated dental caries. Significant differences were observed in the untreated dental caries group based on the KHEI quartiles (P < 0.001). After adjusting for potential confounders, the quartiles of KHEI scores showed an association with untreated dental caries, demonstrating a dose-effect trend (odds ratio [OR], 1.57; 95% confidence interval [CI], 1.35-1.84 for 1st quartile; OR, 1.38; 95% CI, 1.19-1.59 for 2nd quartile; OR, 1.32; 95% CI, 1.14-1.53 for 3rd quartile; reference quartile highest]). CONCLUSIONS: The findings indicated an inverse association between diet quality and untreated dental caries in Korean adults. Healthcare providers should take into account the significant role of diet quality in preventing and managing oral health.
