Purpose: Early diagnosis and treatment of urinary tract infection have been emphasized to prevent renal scarring. If untreated, acute pyelonephritis could cause renal injury, which leads to renal scarring, hypertension, proteinuria, and chronic renal failure. The purpose of this study was to assess risk factors of renal scarring after treatment of acute pyelonephritis (APN). Methods: The medical records of 59 patients admitted at Daegu Fatima Hospital because of APN between March 2008 and April 2015 whose renal cortical defects were confirmed by using initial technetium-99m dimercaptosuccinic acid (DMSA) scans were reviewed retrospectively. We divided 59 patients into 2 groups according to the presence of renal scar and assessed risk factors of renal scar, including sex, age at diagnosis, feeding method, hydronephrosis, bacterial species, vesicoureteral reflux, and vesicoureteral reflux grade. Results: Of 59 patients (41%), 24 showed renal scar on follow-up DMSA scan. No significant differences in sex, hydronephrosis, bacterial species, and fever duration were found between the renal-scarred and non-scarred groups. As for age at diagnosis, age of >12 months had 5.8 times higher incidence rate of renal scarring. Vesicoureteral reflux (VUR) affected renal scar formation. VUR grade III or IV had 14.7 times greater influence on renal scar formation than VUR grade I or II. Conclusion: Our data suggest that the presence of VUR and its grade and age at diagnosis are risk factors of renal scar on follow-up DMSA scan after APN.

This study was to investigate the changes in dietary practices, reasons for making dietary changes, current food consumption patterns, and eating habits. Data were collected from 515 parents whose children were attending an elementary school and a middle school in Kimcheon. Among the twenty food groups studied, subjects reported eating more fruit, vegetables, lower-fat meats, high-fat meats, reduced/skim milk, and eggs and less sugar, fats, rice, salt, potato/sweet potato, and chicken. The changes in dietary practices except high-fat meats and salt were significantly different between sex, age, education level, income level, or BMI groups. The primary reason for making dietary changes was 'concerned about family's health'. The average rate of never eating breakfast or less than 2 times per week was found to be 23.2% with a greater rate in younger age group. The rate of breakfast skipping was found to vary between different age and education groups. The regularity of mealtime and overeating practices were significantly different between age groups. Eating out practices were found to vary between different age, education, and income groups. People at younger age group in Kimcheon should be targeted for nutrition education about eating habits. These findings are applicable at the planning and implementation stages of various nutritional improvement projects.

The purposes of this study were 1) to identify the effects of age and sex on adolescent's psychological characteristics-egocentrism, self-consciousness, body cathexis and clothing behaviors and 2) to identify the effects of psychological characteristics on clothing behaviors in each of the 6 groups classified by sex and age. Egocentrism was measured by Kim's Imaginary Audience Scale, and body cathexis, by the modified record and Jourard"s Body Cathexis Scale. Buss's Self-Consciousness Scale was slightly modified to assess public and private self-consciousness, and five aspects of clothing behavior were assessed with the questionnaires from the previous studies. The questionnaire were administered to 713 middle and high school boys and girls, and college students living in Seoul. Data were analyzed by frequency, factor Analysis, two-way ANOVA, and multiple regression analysis. The results of this study were as follows: 1) Four factors of egocentrism were identified : Potency, Appearance/populatity, Sympathy and Justice. Four factors of clothing behavior were Clothing exhibition/dressing for others, Clothing interest, Psychological dependence, and Clothing conformity. 2) Sex and age were found to have effects on psychological variables and clothing behaviors of adolescence. Females showed higher egocentrism, self- consciousness, clothing behaviors, but lower body cathexis than males. The mean scores of egocentrism, self-consciousness, clothing behaviors tended to increase with age. However, high school boys showed unique tendency, as they showed higher scores in those variables than the other two age groups. 3) Egocentrism (Appearance/populality factor) and public self- consciousness were the most influencial variables on adolescent's clothing behavior among psychological characteristics. Private self-consciousness was found to be an important variable in explaining Psychological dependence.ence.

One hundred and twenty indigenous pigeons of either sexes of different age groups were sacrificed in different seasons to assess the interactions of sex, age and seasons on the proximate composition and gross energy values of fresh boneless meat. The dry matter and protein contents decreased but the fat, ash and energy contents increased linearly as the birds aged. Seasons and age had significant influences on either of these two performance traits. Meat of growing pigeons of both sexes was found to contain high protein and low fat throughout the year.

Purpose : This retrospective study was performed to investigate the prevalence of the idiopathic osteosclerosis (IO) in Korean malocclusion patients according to age, sex, and the Angle's classification of malocclusion. Materials and Methods : This study consisted of 2,001 randomly selected patients from the Department of Orthodontics at the Gangneung-Wonju National University Dental Hospital, Korea. The prevalence of IO in Korean malocclusion patients was recorded using their panoramic radiographs, and the following parameters were surveyed; age, sex, and the Angle's classification of malocclusion. The chi-square test was analyzed to determine the statistical significance of differences in the prevalence of IO between age, sex, and the Angle's classification of malocclusion. Results : The prevalence of IO in the jaws was 6.7% in a total of 2,001 examined orthodontic patients. The majority of IO was found in the mandible (96.58%). The 30-39 age group showed the highest prevalence of IO (9.60%). There was a higher prevalence in females (6.89%) than in males (6.45%). The prevalence of IO in Angle Class I group (7.07%) was the most frequent, followed by Angle Class II group (6.72%), and Angle Class III group (6.40%). However, there was no statistical significance in sex and Angle's classification of malocclusion. Conclusion : The prevalence of IO in malocclusion patients showed the differences between various age groups and most of them were found in the mandibular posterior area. However, sex and the type of malocclusion are not to be considered as a contributing factor of IO.

Background Eyelids vary in morphology and structure depending on age, sex, and race. Usually, one-dimensional measurements are used to evaluate blepharoplasty outcomes. However, in recent years, three- or four- directional enlargements of the eyelid have been used for blepharoplasty in Asian patients, and the outcomes of techniques such as lateral canthoplasty or canthotomy and medial epicanthoplasty with increased scleral area cannot be analyzed using marginal reflex distance 1 or the area of corneal exposure. Therefore, we describe the use of a measurement method based on the eyeball exposure area (EEA). Methods To obtain normal EEA values by age and sex, 320 individuals were recruited. The participants were divided into eight age groups (n=40 in each group: female subjects, n=20; male subjects, n=20): 10-19, 20-29, 30-39, 40-49, 50-59, 60-69, 70-79, and 80-89 years. The EEA value was obtained by dividing the exposed area by the total eyeball area. The normal EEA values and differences in EEA according to age and sex were calculated. Results The mean EEA values for male and female subjects were 66.86% ±9.20% and 71.48%±10.48%, respectively. In each age group, the EEA values of females were higher than those of males. EEA decreased significantly with age in both male and female subjects (P<0.05). Conclusions We determined normal EEA values according to age and sex. EEA can be used as an indicator of the outcome of blepharoplasty.

Backgrounds : Electroacupuncture(EA) is commonly used in treatment of various disease. Despite an extensive evidence-base guiding the selection of stimulation parameters, little methodologically robust research regarding the level of intensity and frequency in need to provide effective doses. Objectives : This study is evaluated effects of various intensities and frequencies of EA's stimulation at $ST_{36}$, Zusanli, with sex and age in rats. Methods : In this study, we measured the effects of EA treatment on transfer capability of small intestine in rats. Under anesthesia, two intensities, 1, 5mA with three different frequencies, 2, 50, 100Hz were applied to the groups divided with sex and age for 30minutes. Results : 1mA-2Hz, 5mA-2, 100Hz in male and 1mA-2, 50, 100Hz in female without distinction of age elicited an increasing trend in transfer capability of small intestine. In case of 2Hz in male, it showed the effects of EA without strength or weakness of stimulation and it need 100Hz stimulation additionally with age. In the groups of 1mA-2Hz, 5mA-2Hz in male and 1mA-2Hz, 1mA-100Hz, we elicited the decreasing trend with growing of weeks-old in male. Conclusions : With this result, it was suggested that we should consider a correlation of sex, age and EA's intensities, frequencies for the efficient EA.

Purpose ; Iension-type headache is the most common headache. The effect of acupuncture for headache is already known, but the methods and technique of acupuncture is varied. Choice of acupuncture points is mostly relied on experience. Moreover, objective evaluation of acupuncture effects is lacking. Objective ; The objective of this study is to assess the difference of effects between dry needling on trigger point and dry needling on remote acupuncture point. The patients who were diagnosed as tension-type headache and administrated herb-medication were divided into two groups: Trigger point dry needling group and remote acupuncture point dry needling group, matching in sex, age. The degree of pain was measured by visual analogue scale(VAS) two times, before and after dry needling. Conclusion ; VAS showed significant decrement after dry needling on tension-type headache in both groups, but there was no statistically significant difference between two groups according to sex, age and duration. In addition, it is not statistically approved that there exists the difference of VAS between two groups about the treatment effects.

Purpose: Malnutrition affects all age groups, but older adults are particularly more vulnerable to nutritional deficiencies. This study evaluated the age-specific factors affecting malnutrition in hospitalized older adults. Methods: A retrospective study was conducted on inpatient elderly people who received artificial nutrition from 2010 to 2017. Data of demographics, diagnosis, type of nutrition therapy, number of comorbidity, fall risk assessment, Acute Physiologic Assessment and Chronic Health Evaluation (APACHE) score, and intensive care unit admission were collected. Malnutrition was defined as a body mass index (BMI) of less than 18.5 kg/m². Patients were classified as the young-old (65~74 years old), the old-old (75~84 years old), or the oldest-old (85 years old or older). Results: A total of 7,130 older adults were included, and 4,028 patients were classified as the young-old, 2,506 into the old-old, and 596 into the oldest-old. Proportion of malnutrition was higher in the oldest-old compared to the other groups. In multivariate analysis, parenteral nutrition, alcohol, and high risk of falls were factors affecting malnutrition in all groups. Parenteral nutrition and alcohol in the young-old, high risk of falls in the old-old, and male sex in the oldest-old were the factors affecting malnutrition by the age group. Conclusion: Older age was the most significant factor affecting malnutrition. Specific strategies by age are needed to improve nutritional status in hospitalized older adults as influencing factors for malnutrition vary among different age groups.

The aim of this study was to assess whether size-rank at the juvenile stage is associated with growth performance and sex ratio in olive flounder (Paralichthys olivaceus). Juveniles (mean body weight, $8.8{\pm}0.9\;g$) were selected from two age groups, with the high size-rank group (HSRG) fish in the upper 19.3-67.3% of 104 days post-hatching (dph) age group and the low size-rank group (LSRG) fish in the lower 9.0-55.7% of 116 dph age group. Triplicate groups of 100 fish were reared over 32 weeks. A heavier final body weight was observed in the HSRG ($360{\pm}12\;g$) compared to the LSRG ($315{\pm}9\;g$, P<0.05), whereas no differences in feed intake, feeding efficiency, and mortality were seen between the experimental groups. The percentage of females was significantly higher in the HSRG (51.7%) than in the LSRG (30.8%, P<0.05). In addition, a remarkable increase in growth was recorded in females, indicating that the relative frequency of females increased with a body weight increase. The results suggest that high size-rank juvenile olive flounder have better growth performance and a higher percentage of females, because females start growing faster than males before size grading occurs.
