  • Purpose: This study investigated the correlation between standing balance and head-forward posture in adolescents. Methods: The participants in this study were 15 female adolescents. We took photographs of the participants' craniovertebral angle with a digital camera to determine the degree of head-forward posture. Standing balance was evaluated using the 30-second Romberg test of BT4. The measurements were taken on a stable-support surface and on an unstable-support surface using a balance pad. The data measured in this study were analyzed using SPSS version 23.0, and the statistical significance level α was established as 0.05. Pearson correlation coefficient analysis was performed to identify the correlation between the degree of head-forward position of the participants and their balance ability. Results: When we measured 30 seconds of the Romberg test, we observed that, with their eyes open, the participants' head-forward posture and balance were not correlated. However, with their eyes closed, there was a strong correlation between the forward position of the head and the balance ability, which declined as the head position increased. Conclusion: Adolescents with severe head-forward posture exhibited problems with balance in posture control with closed eyes when visual information was not available. It can be inferred that an abnormality occurs in proprioceptor sensation due to their habitual head-forward posture. Education on correct posture and preventive activities should be recommended to improve the health of such adolescents and avoid possible future problems of physical deterioration.

  • [Purpose] Sex hormones deficiency leads to dramatically bone loss in particular postmenopausal women. Royal jelly has anti-osteoporosis effect due to maintain bone volume in that condition. We hypothesized that royal jelly protein (RJP, a latent residue after extracting royal jelly) also prevents bone deficient in ovariectomized (OVX) female rats, the animal model of postmenopausal women. [Methods] Female Sprague-Dawley rats (n = 30, 6 weeks age old) were sham operated (Sham; sham operated group, n = 7), OVX control group (OC, n = 7), OVX with low RJP intake group (ORL, n = 8), and OVX with high RJP intake group (ORH, n = 8) during 8 weeks experimental periods. In the end point of this experiment, the bone samples (lumbar spine, tibia, and femur) were surgically removed under anesthesia. These bone samples were evaluated bone mineral density (BMD) and bone strength. [Results] BMD of lumbar spine in RJP intake groups (ORL, ORH) were higher than that in OC group (p < 0.05 and p < 0.01) in RJP intake volume dependent manner. BMD of tibial proximal metaphysis and diaphysis in RJP intake groups were also higher than these in OC group (p < 0.01 and p < 0.01 / p < 0.05 and p < 0.001). In addition, breaking force of femur in RJP intake groups were significantly increase compared with that in OC group (p < 0.001 respectively). [Conclusion] These findings indicate that RJP contribute to prevent sex hormone related bone abnormality.

  • Objective : Several reports have found abnormal levels of androgen in post-traumatic stress disorder (PTSD) patients. This abnormality in androgen is hypothesized to due to chronic psychological stress effects on the hypothalamic-pituitary-gonadal (HPG) system. The present study was conducted to estimate serum testosterone levels in PTSD patients in comparison with normal subjects. Methods : Seventy-five male Korean veterans of the Vietnam War volunteered for the study, of which eleven were excluded because of incomplete psychological assessment. To measure basal serum testosterone, blood samples were collected between 8.00 and 9.30 a.m. The clinician administered PTSD scale (CAPS), the structured clinical interview for DSM-IV (SCID), Hamilton Anxiety Rating Scale (HAM-A), Hamilton Rating Scale for Depression (HAM-D), Mini International Neuropsychiatric Interview Plus (Korean version of MINI-Plus), CES-K (Korean version of combat exposure scale). Results : The serum testosterone level of PTSD patients ($5.4{\pm}2.5ng/mL$) was higher than that of a control group ($3.1{\pm}1.7ng/mL$, p<0.001). Testosterone levels were significantly correlated with CAPS (r=.38, p<.01), HAM-A (r=.35, p<.01) and HAM-D (r=.28, p<.01) in all subjects. Conclusion : The results of the present study suggest that chronic psychological stress affects the HPG system.

  • In old age, measures to cope with the natural phenomenon of aging and various diseases of the elderly due to the deterioration of physical function are also a challenge for this society. While interest in systematic health is increasing, it is true that awareness and interest in oral-related diseases is relatively lacking. This study aims to present basic data necessary to improve the quality of life for senior citizens aged 65 or older by improving the oral dryness caused by systemic health. By research method, improve oral dryness caused by whole-body health with the elderly over 65 and promote their oral health, inducing the increase of the salivary flow rate through oral health care education, oral exercise, and salivary gland massage. First, on the DMSQ according to the general characteristics of the elderly, the recognition of the whole body and oral health status, independent sample t-test and One-way ANOVA were conducted. Second, on changes in the salivary flow rate and saliva pH according to the general characteristics of the elderly, recognition of oral and whole-body health status, and whole-body health, paired samples t-test was conducted. Studies have shown that salivary gland flow increased significantly after oral exercise and salivary gland massage, the salivary flow rate significantly increased. In all variables of the recognition of the oral health status, the salivary flow rate increased after oral exercise and salivary gland massage, and in the whole-body health, regardless of hypertension, diabetes, cardiovascular disorders, and osteoporosis, the salivary flow rate increased after oral exercise and salivary gland massage, and the salivary flow rate increased after oral exercise and salivary gland massage if the subjects responded that they did not have thyroid abnormality, anemia, abnormalities of breathing, hypotension, gastrointestinal disturbance, or kidney diseases. As a comprehensive analysis of this study, many felt oral dryness when they had a problem with the whole-body health, and many felt oral dryness when they had a problem with oral health cognition. After applying oral exercise and salivary gland massage as intervention methods in the oral health care for the elderly, the salivary flow rate significantly increased, and it is judged that the methods were very effective for controlling oral dryness. Furthermore, it is judged that the factors affecting oral health, whole-body health, and oral dryness would be identified, which would be helpful for the promotion of whole-body health and oral health. It is judged that continuous research would be needed so that measures for the application of the oral care program and system for the elderly would be prepared in the future.

  • Purpose: The Oral-anal Transit Test (OTT) is a simple method of obtaining information about colonic transit. We aim to assess the correlation of OTT with the neuromuscular integrity of the colon determined by colonic manometry (CM). Methods: All patients who had OTT followed by CM were evaluated. Less than 6 of 24 markers remaining on OTT was considered normal. CM was performed per previously published guidelines. A normal CM was defined as at least one High Amplitude Propagating Contraction progressing from the most proximal sensor through the sigmoid colon. Results: A total of 34 patients underwent both OTT and CM (44% male, age 4-18 years, mean 11.5 years, 97% functional constipation +/- soiling, Hirschsprung's Disease). Of normal and abnormal OTT patients, 85.7% (6/7) and 18.5% (5/27) respectively had normal CM. When all markers progressed to at least the sigmoid colon, this was 100% predictive against colonic inertia. Greater than 50% of patients with manometric isolated sigmoid dysfunction had markers proximal to the recto-sigmoid. Conclusion: OTT and CM are both valuable studies that assess different aspects of colonic function. OTT can be used as a screening test to rule out colonic inertia. However, the most proximal extent of remaining markers does not predict the anatomical extent of the manometric abnormality, particularly in isolated sigmoid dysfunction.

  • BACKGROUND/OBJECTIVES: The body composition changes in aging increased the risk of metabolic disorder. Recent dietary studies have increasingly focused on the correlations between dietary patterns and chronic diseases to overcome the limitations of traditional single-nutrient studies because nutrients in food have complex relations that interact. SUBJECTS/METHODS: This study was conducted to classify a dietary pattern among Korean elderly using cluster analysis and to explore the relationships between dietary patterns and body composition changes in Korean elderly aged 65 years or older. The study subjects (n=1,435) were individuals who participated in the Korean National Health Examination and Nutrition Survey (KNHANES) in 2011. RESULTS: There were three dietary patterns derived by cluster analysis in this study: 'Traditional Korean' (37.49% of total population), 'Meat and Alcohol' (19.65%) and 'Westernized Korean' (42.86%). The (1) 'Traditional Korean' pattern was characterized by high consumptions of white rice and low protein, low fat, and low milk products, while (2) 'Westernized Korean' pattern ate a Korean-style diet base with various foods such as noodles, bread, eggs and milk, (3) 'Meat and Alcohol' pattern had high consumptions of meat and alcohol. In body composition changes, compared with the 'Traditional Korean' pattern, the 'Meat & alcohol' pattern was associated with a 50% increased risk of having elevated BMI ($kg/m^2$), 'Westernized Korean' pattern was associated with a 74% increased abnormality of ASM/Wt (kg) by logistics analysis. Most of the Korean adult population continues to follow ether a traditional Korean having beneficial effects for successful aging. However, the 'Traditional Korean' pattern showed low protein intake (0.7 g/kg), calcium intake, and vitamin D intake as well as low of appendicular skeletal muscle mass (ASM (kg)) among 3 groups. CONCLUSIONS: Considering the low ASM, consumption of protein, calcium and vitamin D should be increased for Korean elderly health body composition.

  • Purpose: The purpose of this study was to determine whether upright position is effective in labor through systematic review in randomized controlled trials. Methods: We established the PICO (Patient-Intervention-Comparator-Outcome) strategy, and reviewed 282 literatures from national and international electronic databases, and finally selected 9 references based on inclusion and exclusion criteria. We evaluated the quality of references and carried out a meta-analysis. Results: The maternal outcomes showed that the duration of their second-stage labor was 2.29 minutes shorter than that of the women in the recumbent position, and were less likely to have episiotomy. The other outcomes, including the mode of delivery, blood loss, hemoglobin level, use of oxytocin, use of analgesics, and perineal laceration, did not differ between the groups. The fetal heart rate abnormality occurred less than in the control group. The Apgar scores of the groups did not differ. Conclusion: There is evidence that an upright position in the second stage of labor reduces the duration of the second stage of labor, the incidence of episiotomy, and an abnormal fetal heart rate.

  • In the past two decades, structural health monitoring (SHM) systems have been widely installed on various civil infrastructures for the tracking of the state of their structural health and the detection of structural damage or abnormality, through long-term monitoring of environmental conditions as well as structural loadings and responses. In an SHM system, there are plenty of sensors to acquire a huge number of monitoring data, which can factually reflect the in-service condition of the target structure. In order to bridge the gap between SHM and structural maintenance and management (SMM), it is necessary to employ advanced data processing methods to convert the original multi-source heterogeneous field monitoring data into different types of specific physical indicators in order to make effective decisions regarding inspection, maintenance and management. Conventional approaches to data analysis are confronted with challenges from environmental noise, the volume of measurement data, the complexity of computation, etc., and they severely constrain the pervasive application of SHM technology. In recent years, with the rapid progress of computing hardware and image acquisition equipment, the deep learning-based data processing approach offers a new channel for excavating the massive data from an SHM system, towards autonomous, accurate and robust processing of the monitoring data. Many researchers from the SHM community have made efforts to explore the applications of deep learning-based approaches for structural damage detection and structural condition assessment. This paper gives a review on the deep learning-based SHM of civil infrastructures with the main content, including a brief summary of the history of the development of deep learning, the applications of deep learning-based data processing approaches in the SHM of many kinds of civil infrastructures, and the key challenges and future trends of the strategy of deep learning-based SHM.

  • 피부는 인체의 외부를 덮고 있는 기관일 뿐 아니라, 체온을 조절하고, 감각기능을 수행하며, 약물을 투입하는 경로가 되기도 하고 내부 기관의 이상을 표현하는 기관이 되기도 한다. 이러한 이유로 인해, 사람들은 타인의 얼굴 피부의 상태를 보고 건강의 이상 징후를 감지하거나, "안색이 좋다", "생기가 있다" 등으로 신체의 컨디션을 표현해왔다. 환경과 노화정도에 따라서 피부색, 피부결, 수분, 탄력 등이 달라지는 것도 알려진 사실이다. 특히, 피부색은 아름다움, 매력도와 같은 주관적인 인상을 판단하는데 영향을 미치는 인자로 작용하는데, 화장품이나 피부시술을 통해 피부색을 개선하고자 하는 소비자를 통해서 그 수요를 짐작할 수 있다. 하지만 피부색이 여러 색의 구성임에도 불구하고, 대부분의 화장품이 하얀 피부로 개선해주는 것에 초점을 맞추고 있으며 여성들이 선호하는 피부색에 대한 연구가 아직까지는 미흡한 실정이다. 본 연구에서는 30 ~ 40대의 한국여성을 대상으로 같은 피부 밝기에서 붉은 정도와 푸른 정도가 달리 주어진 선호도 조사를 통해 긍정적으로 인식하는 피부색의 상태를 발견하였다. 한국여성은 실제 평균 피부색에 비해 붉은색과 푸른색이 높은 피부를 선호하는 것으로 나타났으며, 피부에 대한 표현을 달리하였을 때에도 경향은 유사하였다. 본 연구 결과는 새로운 소비자의 요구를 만족시키는 제품 개발에 활용될 수 있을 것이라고 생각한다.
