The purpose of this study was to compare the nutrient intakes, blood pressure, and blood lipids in Korean adults according to BMI. Subjects were recruited and divided into three groups according to BMI, which included normal group (18.5$\leq$BMI<23), overweight group (23$\leq$BMI<25), obese group (25$\leq$BMI). The average age, height, weight, BMI of the subjects were 53.1years, 159.2cm, 54.5kg, 21.4kg/$m^2$ for normal group, 52.3years, 159.4cm, 61.4kg, 24.1kg/$m^2$ for overweight group, 55.9years, 158.7cm, 68.5kg, 27.2kg/$m^2$ for obese group, respectively. There were not significant differences in energy and food intakes by BMI groups. The blood pressure, serum cholesterol, serum triglyceride, serum LDL-cholesterol, and AI were significantly increased and serum HDL-cholesterol decreased with increment of BMI. The age and BMI were significantly positively correlated with blood pressure and serum lipids except HDL-cholesterol. There was significantly negative correlation between percentage of protein energy intake and AI. To summarize these results, energy, nutrient, and food intakes were not significantly correlated with BMI, and blood pressure and blood lipids increased with increment of BMI. Further systematic study of relation among nutrient intakes including various life factors, BMI, blood pressure, and blood lipid profile is needed.

This study was performed to compare clinical and diagnostic imaging features between asymptomatic and symptomatic extrahepatic portosystemic shunts in dogs. The data of thirty patients diagnosed with extrahepatic PSS by multi-detector CT were reviewed, and the dogs were divided into asymptomatic (9/30) and symptomatic (21/30) groups. Signalments, hematologic results, liver size, morphologic classifications and main portal vein to abdominal aortic ratio (PV/AO) at the porta hepatis level from CT images were evaluated in two groups. Shih-tzu (5/9) was the most frequent breed in asymptomatic group, and various breeds were presented in symptomatic group. Mean age of asymptomatic group ($9.2{\pm}3.2$ years) was significantly higher than that of symptomatic group ($4.5{\pm}3.2$ years). The most morphologic form of shunt vessel was the splenophrenic shunt (16/30). PV/AO of asymptomatic group ($1.1{\pm}0.19$) was significantly higher than the values of symptomatic group ($0.55{\pm}0.19$). Clinical signs, hematologic results and diagnostic imaging findings of asymptomatic PSS are too nonspecific to suspect PSS. Therefore, considering of patient's age and CT examination with application of PV/AO ratio could be useful for the diagnosis of asymptomatic PSS.

This study investigated factors affecting the bone mineral density (BMD) of Korean adult men. Data on BMD and anthropometric (height, weight, body mass index, BMI, waist circumference, body fat) and biochemical(total cholesterol, vitamin D, alkaline phosphatase, ALP) measurements were obtained from the Fourth and Fifth Korea National Health and Nutrition Examination Surveys (KNHANES, 2008~2011). Overall, BMD of the subjects was decreased from year to year (T-score of 30~39 yr decreased to 0.447 (2010~2011) from 0.106(2008~2009) and in 50~59 yr decreased to 0.234 from 0.033. Age was negatively associated with BMD (T-score 0.361 of 20~29 yr group and -0.894 of ${\geq}80yr$ group in total femoral). According to increase of weight, BMI and waist circumference continuously increased BMD. High value of total cholesterol (T-score 0.157 of 201~<230 mg/dL group and 0.064 of ${\geq}230mg/dL$ group in total femoral) and alkaline phosphatase (T-score 0.337 of ${\leq}102IU/L$ group and -0.270 of ${\geq}336IU/L$ group in total femoral) were associated with lower BMD. Overall height, weight and BMI were positively associated with BMD, and ALP were negatively associated with BMD. Finding of the present study showed that bone loss may be associated with various factors such as age, weight, BMI, total cholesterol, vitamin D and ALP density and that much attention should be paid to bone health of adult men. Therefore, practical and systematic programs are required to improve the BMD of adult men as well as to maintain bone health.

This study was performed to investigate the dental ages of the patients with temporomandibular disorders(TMD), using a method of age estimation by dental attrition, and to compare the differences of dental ages between control and experimental groups. In addition, they were compared according to oral habit. Clinical evaluations for the tooth attrition were to examine the study models of 65 TMD patients (mean age of 26.6 years, aged 18 to 40) had visited to the Department of Oral Medicine and Orofacial Pain Clinic, Dental Hospital, Dankook University as a experimental group and 22 volunteers (mean age of 25.4 years, aged 23 to 36) without TMD as a control group. Age differences were calculated subtracting real age from estimated age. Age differences between experimental and control groups were compared statistically between groups classified according to oral habit. As a results, dental age was increased significantly in TMD patients compared with normal subjects. Oral parafunctions which increased dental age were bruxism, clenching and heavy chewing in order. Conclusively, it should be consider that there can be much discrepancy between real age and age estimated by dental attrition in patients with TMD. In addition, it is suggested that dentists should try to protect the tooth from attrition by various parafunction on treating the patients with TMD.

The purpose of this study was to evaluate the eating behaviors and dietary quality of various aged adults. This study conducted through questionnaire and dietary survey by 24-hr recall to 850 adults residing in Samcheok. Subjects were divided into four groups according to the age in male and female, which included 20~29 yrs group (male n = 94, female n = 66), 30~49 yrs group (male n = 201, female n = 216), 50~64 yrs group (male n = 88, female n = 96), and $\geq65$ yrs group (n = 46, female n = 43). In male, 20~29 yrs group had a larger proportion of subjects who skipped breakfast, lunch and dinner compared to other groups (p < 0.001, p < 0.05, p < 0.01). The daily food and energy intakes in $\geq50$ yrs group were significantly lower than those of < 50 yrs. Protein and fat intakes of 20~29 yrs group were significantly higher than those of the other groups. But ND (Nutrient Density) of minerals as like calcium, iron and plant iron in 20~29 yrs group were significantly lower than those of other groups. The KDDS (Korean's Dietary Diversity Score) of 20~29 yrs group, 30~49 yrs group, 50~64 yrs group and $\geq65$ yrs group in male were 4.1, 3.8, 3.7 and 3.5 respectively and there was significant difference (p < 0.001). In female, skipping breakfast and dinner were significantly higher in 20~29 yrs group than in other groups (p < 0.001, p < 0.001). And the use of nutrient supplementation was higher in 30~49 yrs group than that of other groups (p < 0.05). The daily energy intakes was higher in 20~49 yrs group than that of $\geq65$ yrs group. The ND (Nutrient Density) of animal protein, vitamins A and $B_1$ in 20~29 yrs group were significantly lower than those of other groups. The KDDS of 20~29 yrs group, 30~49 yrs group, 50~64 yrs group and $\geq65$ yrs group in female were 4.0, 3.9, 3.9 and 3.6 respectively and $\geq65$ yrs group was significant lower than other groups. According to these results, $\geq65$ yrs and 20~29 yrs group had more dietary habit problems and poor nutrition status than 30~64 yrs group. The results of this study revealed that nutritional management and education for adequate meals should be emphasized in adults and elderly.

The human semen ejaculated in a form of liquid state, coagulates immediately after ejaculation, and then liquefies again. However, the mechanisms of neither coagulation and liquefaction of semen have not been explained clearly so far, and very limited numbers of report are available, although the spermatology and andrology made rapid progress. This clinical study has been undertaken to investigate the liquefaction phenomena and practicability of the results might be applied to fertility and infertility problems. As a preliminary study, in this report the liquefaction time of various semen groups is measured and analysed. The following results are obtained: 1. An average liquefaction time of semen of a total of 60 subjects: 25 minutes. 2. An average liquefaction time of semen according to sperm count: 1) Normospermia group (20 cases): 34 minutes. 2) Oligospermia group (20 cases): 21 minutes. 3) Azoospermia group (20 cases): 20 minutes. 3. An average liquefaction time of semen according to abstinence period: 1) Less than 3 days group (30 cases): 22 minutes. 2) More then 5 days group (30 cases): 28 minutes. In conclusion: 1. The liquefaction time of semen of the normospermia group is longer than oligospermia group or azoosermia group. 2. The liquefaction time of semen may not be greatly influenced by the various factors such as abstinence period, semen volume, semen pH, age of the subjects and so on. 3. In routine semen analyses, it is recommended to begin the analysis at least 25 minutes after the ejaculation. 4. Further studies are required in conjunction with practical application of liquefaction mechanism in infertility and fertility control.

Opisthorchis viverrini is an ongoing public health problem in Northeast Thailand. Despite continuous efforts for decades by healthcare organizations to overcome this problem, infection rates remain high. To enable related personnel to identify and address the various issues effectively, a cross-sectional study was performed to investigate prevalence and risk factors for opisthorchiasis. The target group was 3,916 Thai residents of Northeast Thailand who were 15 or over. Participants were recruited using the 30 clusters sampling technique. The data were gathered through questionnaires, focus group discussions, in-depth interviews, and stool examinations for parasite eggs (using the Modified Kato Katz method). The data were analyzed using descriptive and inference statistics; in order to ascertain the risk factors and test them using the odds ratio and multiple logistic regressions. The prevalence of opisthorchiasis was 22.7% (95%CI: 0.26 to 0.24). The province with the highest prevalence was Nakhorn Phanom (40.9%; female to male ratio =1:1.2). The age group with the highest prevalence was 40-49 year olds. All age groups had a prevalence >20%. Four of seven provinces had a prevalence >20%. The factors related to opisthorchiasis were (a) sex, (b) age (especially > 50), (c) proximity and duration living near a water body, and (d) eating raw and/or fermented fish. In order to reduce the prevalence of opisthorchiasis, the focus in populations living in upper Northeast Thailand should be changing their eating behaviors as appropriate to their tradition and context.

It is an important task to give adequate nutritions to infants and to wean properly for rapid growth. This study was conducted to survey on doing the weaning activities of the first-time mother. This study was to provide basic data of health teaching and nursing intervention for the promotion of ideal weaning activities. Survey was done from January to February in 2001. Total 444 mothers who have first-time baby under twelve month old were interviewed in five community health center around contry (Seoul, Choung-ju, Asan, Cheon-an, Jeju). The results are summarized as follows; Starting time of weaning was common in four month old(40.4%). Most common daily weaning times by age showed once(under 3 months), twice(4 to 7 months), three times(8 to 12 months). The younger, the more commercial weaning products(p<0.01). Education level showed relatively positive relation with home-made weaning food(p<0.05). Items showed low scores in 4 to 7 months group were starting new food item, waiting at least one week interval to new food, feeding by milk bottle, allowing grasping spoon, consulting pediatrician for problems after weaning, starting from morning, regular schedule. Items showed low scores in 8 to 12 months group were feeding whole egg rather than yolk only up to 12 months, keeping weaning interval were increased, feeding by milk bottle, trying various cooking method, not giving commerical cooking and instant food and unproper raw milk feeding. In weaning activities by general factors, mother age, health status, marriage duration, monthly income were statistically significant (p<0.05). To improve good weening activities, targetting on low maternal age and poor health status, and low income group, developing teaching materials and training program for items showed low scores and proper weaning time, type of easy home-made food and easy cooking method should be provided. Further study on effect of nursing intervention to improve weaning activities are needed.

Purpose: In this descriptive study, we aimed to identify factors influencing safe nursing activities of nurses working at public hospitals. Methods: We collected data in March 2021 through an online survey. The subjects were 199 nurses who had worked for at least six months at public hospitals. The self-reported questionnaire consisted of items pertaining to safe nursing activities, perception of patient safety culture, and the general characteristics of the subjects. To examine the differences in the safe nursing activities and perception of patient safety culture by general characteristics, we employed a t-test and ANOVA. We conducted a multiple linear regression analysis to explore the factors affecting safe nursing activities. Results: The mean score for safe nursing activity was 4.59±0.39. Perception of patient safety culture and age group were found to be the main factors affecting the safe nursing activities of nurses working at public hospitals (F=17.24, p<.001, Adj. R²=.40). When the score for perception of patient safety culture increased by 1 point, the score for safe nursing activities increased by 0.58 points. In addition, the score for safe nursing activity in the 40s age group was 0.16 points higher than for those in the 20s age group. Conclusion: Effective management and leadership in public hospitals is needed to improve the culture of patient safety at various levels so as to ensure safe nursing activities.

Objective : This study compares sensory processing ability of children with and without spastic diplegia. In addition, it investigates characteristics of sensory processing differentiated by developmental phase such as pre-school age versus school age. Methods : Participants in this study are ordinal children without specific condition and children with spastic diplegia who are aged 3 to 10 years olds. Using Short Sensory Profile (SSP), sensory processing function of the participants was measured. The survey was distributed to caregivers of the children from November, 2013 to February, 2014, and it was suggested that the caregivers to record the questionnaire directly after approval from a rehabilitation hospital, a university hospital, welfare center, day care center, preschool and elementary school to participate in our study. Results : Group of children with spastic diplegia showed lower score than group of children with no special condition in the total score and the each score of all items of Short Sensory Profile. There was significant difference between the two groups in terms of the total score of sensory processing and the 5 factors except tactile sensitiveness and taste/smell sensitiveness among the 7 factors of test. In the comparison of different age groups, pre-school age group showed lower total score than school age group. Conclusion : This study provides a foundational evidence that can be used when therapist evaluate sensory processing function of children with spastic diplegia. There is need for more study about sensory processing functions of various types of children with cerebral palsy.
