Purpose: Compared to cities, rural areas are in a medical blind spot and face difficulties in accessing medical services due to inconvenient transportation facilities, lack of medical facilities, and the heavy burden of medical expenses. This study was carried out to identify the problems relating to the musculoskeletal system of the elderly in rural and fishing villages, which are medically vulnerable areas, and sought to present a regionally differentiated healthcare model. Methods: The study was conducted in 80 elderly people in two rural villages and two fishing villages after seeking inputs regarding medically vulnerable groups in the Gyeongnam Province. Postural balance and muscle flexibility were assessed and postural evaluation was conducted to identify musculoskeletal problems and gait stability. Strength and range of motion for each body segment were assessed for evaluating functional motion. Results: The elderly in both rural areas showed forward head posture characteristics. The strength level of the elderly in both rural areas was higher than the average, but their flexibility and balance ability were lower than the average. Conclusion: The musculoskeletal problems of the elderly in rural and fishing villages in this study did not show regional characteristics according to the area of residence. However, overall flexibility and balance ability appeared to be reduced. Therefore, a new management model connecting the region and the university is necessary in preparation for the coming era of community care.

Liquid biopsy, a minimally invasive procedure that causes minimal pain and complication risks to patients, has been extensively studied for cancer diagnosis and treatment. Moreover, it facilitates comprehensive quantification and serial assessment of the whole-body tumor burden. Several biosources obtained through liquid biopsy have been studied as important biomarkers for establishing early diagnosis, monitoring minimal residual disease, and predicting the prognosis and response to treatment in patients with cancer. Although the clinical application of liquid biopsy in gastric cancer is not as robust as that in other cancers, biomarker studies using liquid biopsy are being actively conducted in patients with gastric cancer. Herein, we aimed to review the role of various biosources that can be obtained from patients with gastric cancer through liquid biopsies, such as blood, saliva, gastric juice, urine, stool, peritoneal lavage fluid, and ascites, by dividing them into cellular and acellular components. In addition, we reviewed previous studies on the diagnostic, prognostic, and predictive biomarkers for gastric cancer using liquid biopsy and discussed the limitations of liquid biopsy and the challenges to overcome these limitations in patients with gastric cancer.

Many chapters of the Hwangjenaegyeong[HN] explain the process of transmission and transmutation of disease. The transmission and transmutation process in the HN can be categorized into one between the viscera and bowels, and another of the external pathogenic gi itself. The process between the viscera and bowels indicates the transport of the pathologic burden between each viscera and bowel. This again is categorized into three types. Interpromoting, intercontrolling and that by Saeng-yang(生陽), Sa-eum(死陰). Next, the transport of the pathogenic gi can be categorized into one moving inwards from the exterior according to personal traits, and that according to the three Eum and three Yang. Although there are numerous types of transmission and transmutation, there are two main criteria in understanding the process. First, whether the process is in accordance with the physiological or natural flow of the body. Interpromoting and three Eum three Yang processes are such examples. To follow the physiological flow of the body means to correspond to either the Heaven and Earth or the original physiology of the human body. Therefore, the disease progresses according to a certain date or season. This indicates a partial malfunction in the circulation of the vital energy, which is relatively easy to recover. In contrast, there are processes that go against the physiological flow, for example, intercontrolling transmission and transmutation. This process focuses on the movement of the pathogenic gi rather than the vital gi. The disease progresses regardless of the flow of the vital energy, and sequential functional damage occurs accordingly. Consequently, as the transmission and transmutation continue, formerly passed organs are left damaged, and the whole process is headed towards death. The second criteria for understanding the process is whether it is cyclic or not. To have a cyclic pattern means that the occurrence of a disease and the time of death is not fixed. Transmission and transmutation processes that have a cyclic pattern mostly follow the physiological flow of the body. As a result, they rarely end in deaths, and the process is centered on vital energy. On the other hand, those with acyclic patterns have a fixed occurrence and death point in the course of the disease. They are mostly unnatural processes, found in fatal acute diseases or consumption diseases.

The purpose of this study was to investigate dietary behaviors, body image, hematological index and nutrient intake of female athletes in Incheon. The subjects were 112 female athletes (field and track: n=32, firing: n=27, fencing: n=29, swimming: n=14, badminton: n=10) from middle and high schools in Incheon. This cross-sectional study was conducted by a self-administered questionnaire. Fasting blood samples were obtained and analyzed for hemoglobin (Hb), hematocrit(Hct), ferritin, serum iron, mean corpuscular volume (MCV), mean corpuscular hemoglobin (MCH), mean corpuscular hemoglobin concentration (MCHC), unsaturated iron binding capacity (UBC), total iron binding capacity (TIBC) and transferrin saturation (TS). Nutrient intakes collected from 3 day-recalls were analyzed by the Computer Aided Nutritional Analysis Program. Statistical analysis was conducted using SPSS 10.0 program. The results are summarized as follows: Average age of field and track athletes, firing, fencer and swimmer was 14 years and that of badmintoner was 17 years. Most of female athletes had dietary problems such as unbalanced meals, skipping meals, and preference of processed foods. More than 60% of female athletes skipped breakfast. As for perception of body image, most of female athletes perceived themselves fatter compared to normal body image. Especially, field and track athletes were more significantly experienced weight control compared to the other athletes (p<0.05). As for physical burden during exercise, 56.3% of swimmer and 31.3% of field and track athletes answered “very hard”, which showed a significant difference (p<0.001) More than 80% of female athletes had experienced a vertigo during exercise (p<0.01). Also, more than 50% of female athletes except badmintoner had experienced an irregular menstruation (p<0.05). Average serum iron level (p<0.05) and TS (p<0.05) of field and track athletes were significantly lower compared to the other athletes. Serum ferritin of badmintoner, field and track athletes and fencer was significantly lower compared to firing and swimmer (p<0.05). Nutrient intakes of female athletes except vitamin B6, niacin and phosphorus were lower than the Korean RDA. Especially, calcium and iron intakes of female athletes were under the 50% of the Korean RDA. Therefore, proper nutrition education and supplementation are required for female athletes to encourage desirable food habits as well as to improve their nutritional status and exercise performance.

Due to the popularization of the Extended Reality, research is actively underway to implement human motion in real-time 3D animation. In particular, Microsoft developed Kinect cameras for 3D motion information can be obtained without the burden of facilities and with simple operation, real-time animation can be generated by combining with 3D formats such as FBX. Compared to the marker-based motion capture system, however, Kinect has low accuracy due to its lack of estimated performance of joint information. In this paper, two algorithms are proposed to correct joint estimation errors in order to realize natural human motion in motion capture animation system in Kinect camera-based FBX format. First, obtain the position information of a person with a Kinect and create a depth map to correct the wrong joint position value using the human body segment length constraint information, and estimate the new rotation value. Second, the pre-set joint motion range constraint is applied to the existing and estimated rotation value and implemented in FBX to eliminate abnormal behavior. From the experiment, we found improvements in human behavior and compared errors between algorithms to demonstrate the superiority of the system.

As the country's elderly people who are 65 years or older recently exceeded 10% of the total population with development of medical technology and improvement of living standards, Korea has turned into an aging society. Especially in Gyeonggi-do, as of late December 2012, elderly people who were 65 years or older were 1,135,242 persons, taking up 18.98% of the region's population and registering the largest number of elderly people in the nation's cities or provinces. Due to such a sharp rise in elderly population, support for the elderly is increasing the burden on families and communities. The study aims to take as its subjects elderly people staying at authorized elderly welfare facilities, who are weak in mind and body and have difficulty in daily life with disabilities, or adult day care facilities that take care of elderly people during the day or at night, examine the concept of adult day care facilities and instances in foreign countries, and study the status of the adult day care facilities located in Gyeonggi-do, their services, and safety by figuring out space arrangement based on program implementation. Spacial arrangement in program operation should satisfy fuction and purpose from the manager and user's perspective, and a desirable program operation should provide separate spaces for the elderly with Alzheimer's and those without Alzheimer's. Compared to residential care facilities, adult day care facilities incur less financial burden and, compared to other authorized services, have many right functions that can upgrade the quality of users and satisfy their desires. Major countries like Japan, the UK, and Sweden recognize the right functions of day and night care services and aggressively support and utilize adult day care facilities. For adult day care facilities, quality services should be developed and use and choices should be enhanced as regards services. Development of special programs for the elderly with dementia and stroke, instead of simple protective functions of a program, must be actively promoted, while manpower training is required for program operation, conveniences, and safety. By developing and providing space arrangement models that focus on efficiency, convenience, and safety of program operation, adult day care operation can be revitalized, while quality of elderly care may be enhanced and welfare budget can be saved.

A 3 yr experiment was conducted to evaluate the influence of diet and feeding location on animal performance, carcass characteristics, whole blood counts, and internal parasite burden of lambs assigned to 1 of 4 treatments: 1) confinement fed 71% alfalfa, 18% barley pellet, 5% molasses, 0.013% Bovatec, 6.1% vitamin/mineral package diet (CALF), 2) confinement fed 60% barley, 26% alfalfa pellet, 4% molasses, 2.5% soybean-hi pro, 0.016% Bovatec, 7.4% vitamin/mineral package diet (CBAR), 3) field fed 71% alfalfa, 18% barley pellet, 5% molasses, 0.013% Bovatec, 6.1% vitamin/mineral package diet (FALF), and 4) field fed 60% barley, 26% alfalfa pellet, 4% molasses, 2.5% soybean-hi pro, 0.016% Bovatec, 7.4% vitamin/mineral package diet (FBAR). A year × location interaction was detected for ending body weight (BW), average daily gain (ADG), and dry matter intake (DMI); therefore results are presented by year. In all years, cost of gain and DMI were greater for CALF and FALF than for CBAR and FBAR feed treatments (p ≤ 0.03). In yr 2 and 3 field treatments had greater ending BW and ADG than confinement treatments. For all years, diet did not affect ending BW or ADG. In yr 1 dressing percent and rib eye area were greater for field finished lambs than confinement finished (p ≤ 0.02) and Warner-Bratzler shear force was greater for CALF and FALF (p = 0.03). In yr 2 lambs in FALF and FBAR treatments had greater leg scores and conformation than CALF and CBAR (p = 0.09). In yr 1, FALF had a greater small intestine total worm count than all other treatments. In yr 1, ending Trichostrongyle type egg counts were greater for FALF (p = 0.05). In yr 2, ending Nematodirus spp. egg counts were greater for FALF and lowest for CBAR (p < 0.01). Abomasum Teladorsagia circumcinta worm burden was greater in CALF than all other treatments (p = 0.07) in yr 2. While field finishing lambs with a grain- or forage-based diet we conclude that it is possible to produce a quality lamb product without adverse effects to animal performance, carcass quality or increasing parasite burdens.

To evaluate the effect of lead biomarkers including bone lead on neurobehavioral test in retired lead workers, 131 retired lead workers without any occupational exposure to organic solvent, mercury and arsenic were agreed to participate this study. For the control subjects 56 non-occupationally lead exposed subjects were recruited from same area of retired lead workers with consideration of demographic characteristics. The mean levels of blood and bone lead of retired lead workers were significantly higher than control group and there were significant correlation among other lead biomarkers. Compared with controls without occupational lead exposure, lead exposured subjects had worse performance on 10 tests out of 12 neurobehavioral tests, but only two tests(Purdue pegboard nondominant and both hand) showed statistical significance of differences. In multiple linear regression analysis of neurobehavioral tests with lead biomarkers and demographic and lifestyle variables, age was associated negatively with 11 neurobehavioral tests, whereas log-transformed ZPP was associated with Purdue pegboard(both hand) and Santa Ana manual dexterity(non-dominant hand). On the other hand, tibia lead was associated Pursuit aiming test(correct) and Purdue pegboard(dominant hand) and calcaneal lead was associated with Purdue pegboard(dominant hand). This study confirmed that among all relevant variables age was most significantly associated with the poor performance of neurobehavioral tests. The blood lead did not have any significant association with neurobehavioral tests, but tibia and calcaneal bone lead and blood ZPP showed significant association with a few tests even after more than mean 9 years from their retirements.

The present investigation was designed to determine whether supplementation of different level of vitamin E for 12 months to arsenic exposed goats (50 ppm as sodium arsenite) affords protection against the blood hemato-biochemical parameters caused by the metalloid. A total of 24 crossbred (Alpine${\times}$Beetal) lactating goats were assigned randomly into 4 equal groups (control, $T_1$, $T_2$ and $T_3$) of 6 in each, on the basis of average body weight ($36.10{\pm}0.11$ kg) and milk yield ($1.61{\pm}0.04$ kg/d). The animals in $T_1$, $T_2$ and $T_3$ were given 50 ppm arsenic, while in $T_2$ and $T_3$, additionally; vitamin E at the rate of 100 IU and 150 IU/kg dry matter (DM) respectively was additionally supplemented for the period of 12 months. Hemoglobin (Hb), total leukocyte (TLC) and blood lymphocyte % were decreased (p<0.05) in arsenic fed groups and vitamin E supplementation in the experimental group showed a protective potential. Significant increases (p<0.05) in aspertate transaminase (AST) and alanine transaminase (ALT) activities among arsenic supplemented groups were recorded, however vitamin E supplementation at higher doses showed a protective effect (p<0.05) against AST but in the case of ALT no ameliorating effect was found in either of the doses. Plasma total protein was decreased (p>0.05) but creatinine level was periodically increased in all As supplemented groups and vitamin E supplementation did not produce any protective effect. It can be concluded that arsenic exposure resulted in varying degree of changes in hemato-biochemical parameters and activities of antioxidant enzymes in goats but concomitant treatment with Vitamin E is partially helpful in reducing the burden of arsenic induced effect.
