In this study we tried to examine the efficiency of the agricultural convenient tool (put-on-style-stool) by observing subjects'physiological responses. For this we measured subjects' heart rate, oxygen consumption, blood lactate level, mean skin temperature and rectal temperature. The results of this study are as follows; Heart rate was 75$\pm$2 beats/min with the put-on-style-stool and 78$\pm$2 beats/min without it (P＜0.01). Oxygen consumption was 3.88$\pm$1.90 $m\ell$/kg/min with the Put-on-style-stool and 5. 06$\pm$0.40 $m\ell$/kg/min without it (P＜0.05). Blood lactate level was 2.39$\pm$0.64 mmol with the put-on-style-stool and 3.38$\pm$0.45 mmol without it (P＜0.05). Mean skin temperature was lower but rectal temperature was higher with than without the put- on - style - stool (P＜0.05 and P＜0.01 respectively) So, using the put-on-style-stool was evaluated positively in farmer's work.

Many workers like welders work in squatting postures with the object on the ground during an entire work shift. It is suspected that such prolonged squatting without any supporting stool would gradually cause musculoskeletal injuries to workers. This study is to examine the physical stress caused by the prolonged squatting and to recommend a safe work/rest schedule for a welding task with squatting posture based on the lab experiments. In this study, 8 healthy student subjects participated in the experiment. They maintained a squatting work posture for 16 minutes with 4 different stool height conditions: no stool; 10cm height; 15cm height; and 20cm height. Every 2 minutes, the discomfort was subjectively assessed with the magnitude estimation method for the whole body, lower back, upper leg and lower leg. Based on discomfort ratings, we found that a 10cm height stool relieved the workload most. Discomfort rating results also indicated that a 20cm height stool showed the highest workload, and the there were no difference in workload between a 15cm height stool and no stool. We recommend to use low height stools and to maintain such working postures no longer than 6 minutes for prolonged squatting tasks.

Objectives: This study aimed to investigate the effect of Soeumin-Seonghyangjeongki-san on diarrhea with tube feeding causing mental deterioration induced by subdural hemorrhage (SDH) in an 83-year-old male patient. Methods: The patient was treated with Soeumin-Seonghyangjeongki-san. His symptoms were assessed using the Bristol stool form index, the King's Stool Chart, and records of stool state. The treatment was executed for one week from September 10, 2018 to September 16, 2018. The patient was observed during that same period. Results: After being treated with Soeumin-Seonghyangjeongki-san for seven days, the patient's diarrhea symptoms were evaluated using the Bristol stool form index, the King's Stool Chart, and records of stool state. After the treatment, the results of all three evaluation methods showed that the patient's condition had improved. Conclusions: The results suggest that Soeumin-Seonghyangjeongki-san can be a valuable option for treating diarrhea with tube feeding causing mental deterioration induced by SDH.

Purpose: The aim of this study was to evaluate the correlation among descriptions regarding one's stool, Bristol stool form scale and colon transit time (CTT) in children with gastrointestinal symptoms, along with the clinical significance of Bristol stool form scale. Methods: 489 patients treated in the pediatric department of Severance hospital with gastrointestinal symptoms between May 2002 to May 2004 were included. We analyzed their age, sex, verbal descriptions of stool, Bristol stool form types, and CTT measured by Metcalf's method. Results: 116 children were under 5 years of age, 202 children between 5.1~10, and 171 children 10 years of age or older. Their mean age was $8.2{\pm}3.9years$. Stools were described as loose in 65 children (13.3%), normal in 221 (45.2%), hard in 188 (38.4%), and mixed (loose+hard) in 15 (3.1%). According to Bristol stool form scale, 57 children(11.7%) were classified as type 1, 66 (13.5%) as type 2, 203 (41.5%) as type 3, 109 (22.3%) as type 4, 36 (7.4%) as type 5, 18 (3.7%) as type 6, and 1 (0.2%) as type 7. Their mean CTT was checked $35.9{\pm}19.5hours$. Though no significant relationship was observed between age and CTT (p=0.4), a significant relationship was noted among patient's stool description, Bristol stool form scale and CTT (p<0.001). However, concordance between stool description and Bristol stool form was relatively low in the loose stool group (29%) and normal stool group (37%) while high in the hard stool group (87%). Conclusion: Bristol stool form scale could be used in the estimation of CTT in clinical practice.

Purpose: Digital communication is becoming increasingly important in clinical practice and research. The finding that stool consistency can be evaluated similarly using either "in vivo" or photographic material by health care professionals will decrease subjective interpretation by parents. The primary outcome of this study was the reliability of stool consistency scoring using the Brussels Infant and Toddler Stool Scale (BITSS) between fresh stools and their photos; the secondary outcome was the inter-rater reliability based on the fresh stools. Methods: Fresh stool samples from healthy children were collected in a day care center. These stools, and one month later the corresponding photos presented in a random order, were presented to 14 observers. Reliabilities were analyzed using absolute agreements and weighted and unweighted Cohen's κ. Results: In total, 202 samples were rated 576 times. Absolute agreement between photographic and real time assessment ranged between 71.1% and 83.3% among observers. This corresponded with substantial agreement (unweighted κ=0.70 [95% CI, 0.61-0.78]; weighted κ=0.86 [95% CI, 0.78-0.88]). The inter-observer agreement showed similar percentages of absolute agreement (81.4-82.0%) and κ-values corresponding with fair-to-moderate agreement. Conclusion: Our findings suggest that the assessment of fresh stool consistency can also reliably be done on photographic material when using the BITSS. This opens opportunities in scientific surroundings and in our daily life communication with parents and caretakers.

This study investigated the water saving technology for the toilet stool system in a water closet. Since in 21st century water would be the prospected factor to measure the wealth of a country instead of the oil, water saving technologies in the toilet stool in a closet system is getting more important than the cleaning stool and the reducing noise performances. According to the statistics in Korea the percentage of using water in toilet is about 27% to the total amount of water used. Therefore, this study theoretically approached the possible amount of water saving and suggested the new variable position straight trap device in the toilet stool system.

Purpose: To evaluate the efficacy of synbiotic formula with partial whey hydrolysate and high magnesium content in infants presenting with functional constipation. Methods: Sixty-five infants with functional constipation were included. Forty infants were treated during one month with parental reassurance and the intervention formula and were compared to a control group of 25 infants treated with parental reassurance only. Parents completed a quality of life (QoL) questionnaire at baseline and during the last week of the study. Results: At inclusion, stool characteristics and QoL were similar in both groups. The control group was slightly older than the intervention group ($7.5{\pm}3.9$ vs. $6.2{\pm}3.6$ weeks). At onset, stool composition was "hard and tight" (Bristol stool scale 1 and 2) in all infants. After one month, stool composition remained unchanged in the control group except in two infants that developed "creamy" stools (Bristol stool scale type 3 and 4). In the intervention group, stools remained "hard and tight" in 27.5%, and became "creamy" in 47.5%, "loose" (Bristol stool scale type 5) in 22.5% and "watery" (Bristol stool type 6 and 7) in 2.5%. The benefit of the intervention formula was estimated to be "very important" in 70%. The median scores for QoL improved significantly in the intervention group for all parameters and for one in the control group. Conclusion: The intervention formula significantly improved functional constipation resulting in a better QoL of the parents and infants.

Background: A diagnosis of H. pylori infection can be made by invasive or non-invasive methods. Several noninvasive diagnostic tests based on the detection of H. pylori stool antigen (HpSA) have been developed. The Genx H. pylori stool antigen card test is a new rapid, non-invasive test that is based on monoclonal immunochromatographic assay. The aim of this study was to determine its sensitivity, specificity, and diagnostic accuracy for diagnosing H. pylori infection in adult patients. Materials and Methods: A total of 162 patients were included in the study. A gastric biopsy was collected for histopathology and rapid urease testing. Stool specimens for HpSA testing were also collected. Patients were considered H. pylori positive if two invasive tests (histological and rapid urease tests) were positive. Results: Using the reference test, 50.6% of the samples were positive for H. pylori infection. The Genx H. pylori antigen test was positive in 19.7% of patients. The sensitivity, specificity, positive predictive value, negative predictive value, and diagnostic accuracy of the Genx H. pylori antigen test were 51.6%, 96.0%, 88.8%, 76.1%, and 79.0%, respectively. Conclusions: The Genx H. pylori stool antigen card test is a new non-invasive method that is fast and simple to perform but provides less reliable results.

Amebiasis is a protozoan disease caused by Entamoeba histolytica and a potential health threat in areas where sanitation and hygiene are inappropriate. Highly sensitive PCR methods for detection of E. histolytica in clinical and environmental samples are extremely useful to control amebiasis and to promote public health. The present study compared several primer sets for small subunit (SSU) rDNA and histone genes of E. histolytica cysts. A 246 bp of the SSU rDNA gene of pure cysts contained in phosphate-buffered saline (PBS) and in stool samples was successfully amplified by nested PCR, using the 1,147-246 bp primer set, of the primary PCR products which were pre-amplified using the 1,147 bp primer as the template. The detection limit of the nested PCR using the 1,147-246 primer set was 10 cysts in both groups (PBS and stool samples). The PCR to detect histone gene showed negative results. We propose that the nested PCR technique to detect SSU rDNA can be used as a highly sensitive genetic method to detect E. histolytica cysts in stool samples.
