An experiment was conducted to investigate the relationship between blood hormone levels and light cycle on performance of Korean native chicken. One hundred and two Korean native chickens were grouped into three treatments of natural light cycle (Control), 13L:11D (T2), and 16L:8D (T3). The egg production, egg weight, feed intake, serum melatonin and estrogen level were periodically measured from 22 to 34 weeks, respectively. The laying rates of T2 and T3 were significantly higher than that of the Control (P

Improvement in prenatal ultrasonography is leading to diagnose choledochal cyst before birth and before onset of classical symptom more frequently. But, there is a controversy about optimal timing for Cyst excision of prenatally diagnosed asymptomatic choledochal cyst. To identify the most appropriate timing for surgery in prenatally diagnosed choledochal Cysts, we analyzed 6 patients who had operation for choledochal cysts within 30days after birth at the division of Pediatric Surgery, Samsung Medical Center and Inha University School of Medicine, from June 1995 to June 2002. Males were four and females 2, the mean age at operation was 11.2 days, and the median age 8.0 days. The range of gestational ages of the antenatal diagnosis of bile duct dilatation was 24 weeks to 32 weeks, mean was 38.3 weeks, and mean birth weight was 3,298.3 g. After birth, abdominal ultrasonography, hepatobiliary scintigraphy, and magnetic resonance cholangiopancratography (MRCP) were performed. Mean age at operation was 11.2 days. All patients had the cyst excision and Rouxen-Y hepaticojejunostomy. Immediate postoperative complication was not found. During the median follow-up period of 41 months, one patient was admitted due to cholangitis, and the other due to variceal bleeding. Early operative treatment of asymptomatic newborn is safe and effective to prevent developing complications later in life.

The results were as follows. 1. In the incidence of decreased visual acuity, men's was $46.84\%$(37 cases) and women's was $53.16\%$(42 cases), which showed that more women were suffering decreased visual acuity than men. In the incidence of myopic ametropia and astigmatic ametropia among the total patients, men's was $44.62\%$(29 cases) and $37.50\%$(9 cases) each, and women's was $55.38\%$(36 cases) and $62.50\%$( 15 cases) each, which also showed that more women were suffering myopia and astigmatism than men. 2. The average age of patients was 11.08 years at the first visit. The most were the patients from 6 to 15 years old, with 63 cases($79.74\%$). 3. The age of onset in the decreased visual acuity was mainly 6∼10 years with 45 cases($56.96\%$). In the case of myopic ametropia and astigmatic ametropia, the age of onset was also mainly 6∼10 years with 65 cases($60.00\%$), and with 12 cases($50.00\%$) each. 4. In ABO blood type, the frequency was, A type, O type, B type and AB type in order. In men, O type was the most, while in women, A type. 5. In the liking for cool or warm food or tepidity, the liking for cool food was the most in both men and women. 6. The type of decreased visual acuity was mainly myopic ametropia with 65 cases($82.28\%$). Astigmatic ametropia was $30.38\%$ with 24 cases, hyperopic ametropia $2.53\%$ with 4 cases, and the decreased visual acuity accompanied by amblyopia $7.59\%$ with 4 cases. 7. At the first visit, the average visual acuity of O.D. was 0.29 and that of O.S.. 0.24, which showed that O.S.. is worse than O.D.. The visual acuity below 0.2 was the most, $63.29\%\;in\;O.D..\;72.15\%$ in O.S.. 8.

Purpose: This study was carried out to identify factors influencing osteoporosis in women at pre- and post-menopausal state. Methods: The subjects of this study were 52 pre-menopausal and 125 post-menopausal women who were assessed of bone density in one general hospital. The data were collected through review of clinical records and telephone interviews using a questionnaire. Results: In the pre-menopausal women, the factors influencing osteoporosis were regular exercise (protective factor) and age (risk factor). Regression analysis showed that the factors attributable to osteoporosis included educational level, weight, age and number of pregnancy, accounted for 41.89% of the total variance. In the post-menopausal women. the factors influencing osteoporosis were age (risk factor), low educational level (risk factor), low economical state (risk factor), high parity (risk factor), and intake of coffee (protective factor). Regression analysis also showed that factors attributable to their osteoporosis included age, educational level, number of delivery, intake of the coffee, regular exercise, number of pregnancy and duration of oral pill intake, accounted for 37.41 % of the total variance. Conclusion: In pre-menopausal women, regular exercise was one of the most powerful determinant of their bone mass. Therefore, it is necessary to participate in a regular exercise program to maintain peak bone mass density prior to the onset of menopause. In post-menopausal women, increased age was the most influencing factor of their bone mass. Therefore, it is essential to establish early diagnosis and management of osteoporosis after menopause.

Background: Oral frailty is defined as the functional decline of the oral function due to aging, and it is associated with frailty and chronic disease. Most of the frailty intervention is for adults aged 65 years and older. However, early intervention for preventive disorder is most important. The objective of this study was to identify the age at which oral frailty surpass the "normal" range. Methods: This cross-sectional study included 719 adults (aged 30~89 years) residing in Gangwon province in May 2023. Risk of oral frailty was assessed using criteria from The Korean Academy of Geriatric Dentistry including oral function such as swallowing and mastication, and frailty. Frailty was assessed using the Kihon Checklist. To determine when oral frailty surpass the "normal" status, statistical analysis including chi-squared tests and multiple logistic regression analysis were performed using R (ver. 4.3.1). Results: There were 388 (54.0%) individuals who had a "normal" status risk of oral frailty. The risk of oral frailty was higher in the 50~54 age group compared to the 30~34 age group (odds ratio [OR] 0.50, 95% confidence interval [CI] 0.28~0.91), after adjusting for gender, education, income, occupation, and frailty (OR 0.46, 95% CI 0.22~0.94). This means that from 50~54 years old, regardless of gender, education, income, occupation, or frailty condition, there is a distinction from the "normal" status. Conclusion: We found that intervention for oral frailty is needed starting from age 50 years. This is the stage where early indications of oral frailty become apparent. Early intervention for oral frailty can lead to a decrease in the prevalence of diseases and medical expenditure. Therefore, early intervention in middle-aged adults of oral frailty is necessary to improve the quality of life related to oral health.

Background: Promoting patients' safe return home at discharge and reducing length of stay in hospital is key for Restorative Rehabilitation Institution (RMI). Objects: This study was designed to identify the factors influencing the return to home and length of stay among various factors. Methods: A total of 120 stroke patients (76 males and 44 females) who were hospitalized in an adult inpatient unit of a RMI for more than 2 months were retrospectively analyzed for this study (multivariate logistic regression analyses, p < 0.001). As predictor variables for assessing the return to home and length of stay, demographic data (sex, age, duration between onset and admission, length of stay, caregiver after discharge, occupation after discharge, reason for discharge, and household type after discharge) were collected. Additionally, following measurements were selectively collected from patient's medical records: scores of Mini-Mental State Examination Korean version (K-MMSE), modified Barthel Index Korean version (K-MBI), Berg Balance Scale and Functional Ambulation Category were obtained at admission and discharge. Results: The K-MMSE at admission and K-MBI at discharge were found to be the predictors of return to home. Additionally, K-MBI at admission influenced the length of stay. Conclusion: This study suggests cognitive functioning at admission and the level of activities of daily living at discharge predicted the return to home and length of stay.

The main purposes of this study were to determine the time interval between the onset of symptoms of myocardial infarction and treatment-seeking time and to identify the factors related to the interval time. This study used a retrospective design. The sample consisted of 45 patients aged over 30 who were diagnosed with an acute myocardial infarction at two large university affiliated medical center from September 1, 1997 to June 30, 1998. Data was collected by using questionnaries, which included demographic data, permonitory clinical signs and symtoms of myocardial infarction, and a measure of the severity of the signs and symptoms. Also semi-structured interviews and chart reviews were used to obtain information related to treatment-seeking time. The results of this study are summarized as follows ; 1. The most frequent premonitory clinical symptom was chest pain(92.9%), the second, was perspiration(81.0%), and the next were nausea(40.5%) and dyspnea(38.1%). Thirty two patients reported having more than four premonitory signs and symtoms. Patients described the characteristics of chest pain as “somethings very heavy pressing down”(26.2%), “felt like my chest would burst”(24.4%), or “sharp pain”(16.7%), Over 95% of the sample reported having chest pain. 2. Twenty two (52.4%) patients reported to have “very severe” premonitory pain. 3. The mean time interval between the onset of signs and symptoms and the arrival at the medical center was 6.39$\pm$10.80 hours in 42 samples, the mean time from the onset to arrival at a local hospital was 3.27$\pm$5.39 hours and for transfer from a local hospital to the medical center was 4.75$\pm$9.87 hours in patients who had arrived at medical center via local hospital. 4. The severity of premonitory signs and symptoms did not differ significantly according to existence of premonitory signs and symptoms. 5. There was no significant relationship between treatment-seeking time and age, gender, marital status, economic status, occupation, or residence. But education had significant relationship(r＝－0.51, p＝0.01). Analysis of difference of the time interval according to the premonitory signs and symptoms showed that the time was shorter in patients who experienced nausea or dyspnea(U＝115.50, p＝0.01, U＝132.00, p＝0.04), however the severity of premonitory signs and symptoms did not have statistical significance.
