본 연구는 사무직 근로자를 대상으로 비타민 D 상태와 생활습관위험인자간의 연관성을 조사하고자 하였다. S시의 30세 이상 사무직 근로자 515명(남 336명, 여 179명)을 대상으로 혈청 비타민 D 수준, 비만지표, 체력, 대사성위험인자 및 혈중 지질 그리고 좌식습관을 포함한 생활습관위험인자를 측정하였다. 혈청 비타민 D 수준을 기준으로 결핍(<20 ng/mL), 부족(20-29 ng/mL), 충분(≥30 ng/mL) 집단으로 구분하고, 집단 간 생활습관위험인자를 비교하였다. 분석결과, 비타민 D 수준이 높아질수록 체지방율(p=.030)과 좌식습관(p<.001)은 통계적으로 유의하게 감소하는 선 경향성이 나타났으며, 골격근량(p=.037), 심폐체력(p<.001) 그리고 HDL-C(p=.013)은 통계적으로 유의하게 증가하는 선 경향성이 나타났다. 또한 심폐체력이 낮은 집단이 높은 집단보다 비타민 D 부족 또는 결핍에 노출될 상대적 위험도가 남녀 각각 2.144배(95%CI .469-1.808, p=.042), 1.971배(95%CI .305-1.974, p=.045) 정도 높게 나타났으며, 좌식시간이 가장 많은 집단이 가장 적은 집단보다 비타민 D 부족 또는 결핍에 노출될 상대적 위험도는 여성 사무직 근로자 집단에서만 1.262배(95%CI 0.074-1.527 p=.043) 정도 높게 나타났다. 이와 같이 본 연구에서는 사무직 근로자의 낮은 비타민 D 수준은 낮은 심폐체력 및 장시간의 좌식습관과 관련성이 있는 것으로 나타났다. 따라서 사무직 근로자의 건강증진과 충분한 비타민 D 공급을 위해 건강한 생활습관 변화와 근무 환경 개선이 우선적으로 필요할 것으로 판단된다.

Objectives : The purposes of this study were to investigate that a blepharospasm means the presymptom of stroke based on the traditional hypothesis in the oriental medicine and to compare a blepharospasm with warning signs of stroke in the western medicine. Methods : In the time period Oct. 2005 to Oct. 2006, 409 patients with a first-ever stroke admitted in the department of Internal Medicine of Kyungwon University In-cheon Oriental Medical Hospital, Kyunghee University Oriental Medical Hospital, Dongguk Il-san Oriental Medical Hospital were included. Patients were hospitalized within 14 days after the onset of stroke. Stroke patients were interviewed by residents who studied standard operation procedures in Fundamental Study for Standardization and Objectification of Differentiation and Pattern Identification of Syndrome of Oriental Medicine for Stroke. A questionnaire was completed by a question-and-answer form between patients and residents after explanation details to patients and the agreement of patients. Results : Age, care of patients or grandson, diabetes mellitus, and smoking were higher among cerebral infarction group, while smoking was higher among hemorrhage group. Female, young age, hyperlipidemia, hypertension in the family history and fat body in waist-hip ratio were higher among patients undergoing the blepharospasm before stroke onset. And the incidence of blepharospasm was lower in patients who dislike the fast food. Finally, when we compared a blepharospasm with warning signs of stroke in the western medicine, the incidence of blepharospasm in this study were the most frequent. Conclusion : In this study, the incidence of blepharospasm in patients before stroke onset was more frequent than that of warning signs in the western medicine. But more data from prospective cohort studies should be collected to be accepted that the blepharospasm is the presymptom of stroke as like warning signs in the western medicine.

BACKGROUND/OBJECTIVES: This study aimed to identify preschool children's eating behaviors associated with early childhood obesity and its multi-level, socio-ecological determinants. SUBJECTS/METHODS: In a cross-sectional study of 364 mothers of preschool children aged 3-5 years, these children's healthy eating behaviors were assessed using a validated preschool nutrition quotient (NQ-P) questionnaire. The children's overweight or obesity statuses were determined based on body mass index percentiles from the 2017 Korean National Growth Chart. The associations between the NQ-P score and risk of overweight or obesity were examined using multivariable logistic regression. The associations of individual, maternal, physical, and media environmental factors with the NQ-P score were also examined using multivariable linear regression. RESULTS: Preschool children with greater NQ-P scores were at a significantly lower risk of overweight or obesity (P < 0.01). The NQ-P score had a significantly positive association with maternal body mass index and an inverse association with household income (all P < 0.05). Maternal parenting and feeding practices exhibited associations with the NQ-P score. Positive associations were observed with "warm," "structured," and "autonomy-supportive" parenting as well as monitoring feeding practices (all P < 0.05). In addition, the NQ-P score had a significantly positive association with the childcare center's anti-obesogenic environment, such as the provision of nutritional and physical-activity support and vicinity of the built food environment to the home, including access to good-quality food, fruits and vegetables, and low-fat foods (all P < 0.05). Regarding media environments, the NQ-P score demonstrated more significant associations with viewing and eating and/or cooking content displayed on online video platforms (all P < 0.05) than with that on television. CONCLUSIONS: Our findings confirm the significance of healthy eating behaviors in early-childhood-obesity prevention and underscore the importance of multilevel maternal, physical, and media environmental interventions that effectively guide eating behaviors in preschool children.

The purpose of this study was to investigate the effects that body composition, nutrient intake, and biochemical indices have on skin status, as well as their associations with skin health status, by assessing 44 female university students. The subjects were classified into 3 groups according to skin sensitivity: sensitive skin (n=11), slightly sensitive skin (n=24), and normal skin (n=9). The study included anthropometric measurements and body composition analyses, dietary intake evaluations, blood chemical analyses, and skin health status assessments. Based on % body fat, the results indicated the subjects were moderately obese (29.6%). Obesity indices were not different among the groups, but the sensitive skin group tended to have higher skinfold thickness. Dry skin was determined as the skin type of all subjects. In the sensitive skin groups, U-zone and T-zone sebum were significantly lower (p<0.05), and spots were significantly higher (p<0.05) than in the normal skin group. In terms of nutrient intakes, the sensitive skin groups consumed significantly lower amounts of P and vitamins A and E (p<0.05). There were no significant differences in serum lipid fractions or total antioxidant status among the groups. In correlation coefficients analysis, skin elasticity had significant negative correlations with subscapular and midaxillary skinfold thickness, body protein, and body minerals (p<0.05). Wrinkling had positive correlations with triceps and thigh skinfold thickness (p<0.05). Skin evenness had negative correlations with energy intake, vitamins A, $B_1,\;B_2$, C, E, niacin, and zinc (p<0.05), as well as folate and P (p<0.01) and vitamin $B_6$ (p<0.001). A similar correlation tendency was observed for spots and nutrient intake, showing negative correlations with vitamins A, $B_6$, and E, as well as folate, Fe, and P. U-zone sebum showed significant positive correlations with serum levels of total cholesterol and triglycerides. From these findings, skin health status appears to be affected by both nutrient intake and body composition. Therefore, having a proper balance between dietary intake and body composition may influence skin health status in females with sensitive skin.

In Korea, Korea Proven Bulls (KPN) program has been well-developed. Breeding and evaluation of cows are also an essential factor to increase earnings and genetic gain. This study aimed to evaluate the accuracy of cow breeding value by using three methods (pedigree index [PI], pedigree-based best linear unbiased prediction [PBLUP], and genomic-BLUP [GBLUP]). The reference population (n = 16,971) was used to estimate breeding values for 481 females as a test population. The accuracy of GBLUP was 0.63, 0.66, 0.62 and 0.63 for carcass weight (CWT), eye muscle area (EMA), back-fat thickness (BFT), and marbling score (MS), respectively. As for the PBLUP method, accuracy of prediction was 0.43 for CWT, 0.45 for EMA, 0.43 for MS, and 0.44 for BFT. Accuracy of PI method was the lowest (0.28 to 0.29 for carcass traits). The increase by approximate 20% in accuracy of GBLUP method than other methods could be because genomic information may explain Mendelian sampling error that pedigree information cannot detect. Bias can cause reducing accuracy of estimated breeding value (EBV) for selected animals. Regression coefficient between true breeding value (TBV) and GBLUP EBV, PBLUP EBV, and PI EBV were 0.78, 0.625, and 0.35, respectively for CWT. This showed that genomic EBV (GEBV) is less biased than PBLUP and PI EBV in this study. In addition, number of effective chromosome segments (M_e) statistic that indicates the independent loci is one of the important factors affecting the accuracy of BLUP. The correlation between M_e and the accuracy of GBLUP is related to the genetic relationship between reference and test population. The correlations between M_e and accuracy were -0.74 in CWT, -0.75 in EMA, -0.73 in MS, and -0.75 in BF, which were strongly negative. These results proved that the estimation of genetic ability using genomic data is the most effective, and the smaller the M_e, the higher the accuracy of EBV.

Objectives: Interventions promoting physical exercise and healthy habits in workplaces have been shown to be effective in reducing risk factors for metabolic syndrome. This study was conducted to examine the effects of an individualized conditioning exercise program of IT company office workers with or at higher risk of metabolic syndrome. Methods: A total of 444 IT company office workers with or at higher risk of metabolic syndrome participated in a 3-month conditioning exercise program. Body composition data using bioelectrical impedance analysis and cardiopulmonary data using cardiopulmonary exercise testing from 53 individuals (mean age: 34.8 ± 7.1 years, sex : 21% female, height : 170.4 ± 6.8 cm, weight : 75.2±12.2 kg, body mass index : 25.8±3.3 kg/m²) who have successfully completed pre-test, intervention, and post-test were analyzed. The 12 weeks intervention encompassed: (1) health counseling (2) supervised exercise(endurance-based, aerobic exercise, or circuit training once a week for 50 minutes at heart rate reserve(HRR) of 77-95%) (3) self-directed exercise and biweekly health screening checks. Results: The results indicated a significant decrease in body weight, body fat mass and body mass index, respectively. Moreover, VO₂peak, AT VO₂ and AT Time significantly improved, respectively. Resting blood pressure(SBP/DBP) showed positive changes but were not statistically significant. We observed the correlation between characteristics of participants and rate of changes in cardiopulmonary outcomes of participants, there are no significant correlation. These results indicate positive changes in body composition and cardiorespiratory fitness parameters following individualized conditioning exercise program. Conclusions: Individualized workplace exercise program for preventing metabolic syndrome can lead to improvements in body composition and cardiorespiratory fitness.

Objective: To investigate the association between functional tumor burden of peritoneal carcinomatosis (PC) derived from diffusion-weighted imaging (DWI) and overall survival in patients with advanced ovarian carcinoma (OC). Materials and Methods: This prospective study was approved by the local research ethics committee, and informed consent was obtained. Fifty patients (mean age ± standard deviation, 57 ± 12 years) with stage III-IV OC scheduled for primary or interval debulking surgery (IDS) were recruited between June 2016 and December 2021. DWI (b values: 0, 400, and 800 s/mm²) was acquired with a 16-channel phased-array torso coil. The functional PC burden on DWI was derived based on K-means clustering to discard fat, air, and normal tissue. A score similar to the surgical peritoneal cancer index was assigned to each abdominopelvic region, with additional scores assigned to the involvement of critical sites, denoted as the functional peritoneal cancer index (fPCI). The apparent diffusion coefficient (ADC) of the largest lesion was calculated. Patients were dichotomized by immediate surgical outcome into high- and low-risk groups (with and without residual disease, respectively) with subsequent survival analysis using the Kaplan-Meier curve and log-rank test. Multivariable Cox proportional hazards regression was used to evaluate the association between DWI-derived results and overall survival. Results: Fifteen (30.0%) patients underwent primary debulking surgery, and 35 (70.0%) patients received neoadjuvant chemotherapy followed by IDS. Complete tumor debulking was achieved in 32 patients. Patients with residual disease after debulking surgery had reduced overall survival (p = 0.043). The fPCI/ADC was negatively associated with overall survival when accounted for clinicopathological information with a hazard ratio of 1.254 for high fPCI/ADC (95% confidence interval, 1.007-1.560; p = 0.043). Conclusion: A high DWI-derived functional tumor burden was associated with decreased overall survival in patients with advanced OC.
