Objective: The purpose of this study was to determine breast shape and ratio of breast enlargement women prior to development of breast enlargement patient's bra. Background: Although there are many previous studies on women's breast that did not undergo breast augmentation surgery, no studies have examined the breast type and proportion of women with breast augmentation. Method: In this study, we analyzed ratios and angles with photographs taken before and after breast augmentation on the frontal and lateral views of the breast, UPF and projection were analyzed too. We also compared the pre-operative and post-operative rates with those of previous breast studies, as well as the post-operative breast types for the desirable breast types. Results: The length and width of the breast base and the height of the breast projection increased after the operation. The rate of increase in width is larger than the vertical distance in the breast base, and the rate of increase in height of the projection is larger than the increase in the width. Specifically, in the vertical distance, the rate of increase in the lower portion is larger than that in the upper portion. In the width, the rate of increase on the inside is larger than that on the outside. Conclusion: The angles of the static relationship with the projection increased and the angles of the minor relation decreased. The changes in the size of the breast were visually observed in the overlapping of the triangle shape before and after the surgery. The changes were composed of the line connecting the angle and the measurement points. The pre-operative upper pole fullness (UPF) was mostly 0 and - 1, but after the surgery, +1, 0, -1, +2 were distributed, while post-operative levels of projection were distributed in the order of level 3> level 1> level 2. In comparison with the desirable breast type, it was found that the anatomical type was a more natural breast type than the round type of implant. Application: These results can be useful as basic data for the breast analysis of breast enlargement patients and their bra patterns.

Objective: The purpose of this study was to analyze the correlation between Stomach Qi Deficiency and gastric emptying as measured by abdominal ultrasonography in postprandial distress syndrome (PDS), a subgroup of functional dyspepsia (FD). Methods: Ten patients who met the Rome III diagnostic criteria for PDS and ten healthy controls participated in this study Gastric emptying shown as the half-life of gastric volume ($T_{1/2}$) was measured by abdominal ultrasonography. The degree of Stomach Qi Deficiency was assessed using the scale for Stomach Qi Deficiency pattern (SSQD). In addition, functional dyspepsia-related quality of life (FD-QoL), Nepean dyspepsia index-Korean version (NDI-K), and visual analogue scale (VAS) of distention and fullness were conducted on all subjects. Results: The scores of SSQD, FD-QoL, NDI-K, and VAS of distention and fullness in the patient group were significantly higher than those in the control group (p<0.05). $T_{1/2}$ was also higher in the patient group than in the control group. The SSQD score significantly correlated positively with $T_{1/2}$ in the patient group (r=0.640, p=0.046). However, there was no significant correlation between $T_{1/2}$ and other questionnaire scores in the patient group. Conclusions: Our results suggest that the gastric emptying measured by abdominal ultrasonography could be a quantitative indicator to diagnose Stomach Qi Deficiency in FD patients, especially the PDS subtype.

Although Pacific mackerel (Scomber japonicus) is an important commercial species in Korea, its recruitment mechanism remains largely unknown. Diel vertical positioning of larvae in the water column, which is affected by their specific gravity and the surrounding water density, may help to provide an understanding on recruitment success through predator avoidance and prey availability. The specific gravity measurement on Pacific mackerel eggs and larvae would seem to be essential information necessary to learn about the transport process from spawning to nursery grounds, and consequently the recruitment success. Eggs were artificially fertilized, and larvae were fed with rotifer when their mouths opened 3-4 days after hatching. We conducted the experiment using a density gradient water column to measure the ontogenetic changes in specific gravity from fertilization to 10 days after hatching. Egg specific gravity was stable during most of the embryonic period, but a sudden increase to $1.0249g\;cm^{-3}$ happened just before hatching. However, the specific gravity of newly hatched larvae was much lighter ($1.0195g\;cm^{-3}$), and specific gravity tended to increase continuously after hatching. Comparison of specific gravity with seawater density reveals that eggs and newly hatched larvae can float in the surface layer of the ocean. For the later period of the experiment, the specific gravity showed a cyclic diel pattern: the highest in the evening while the lowest at dawn. The fullness of larval stomach may be responsible for the observed differences in specific gravity, because stomach fullness was lower (40-60%) at midnight, and higher (80-85%) in evening. The diel pattern of specific gravity might provide clues regarding how larvae match the diel vertical migration of prey organisms.

Objectives The purpose of this study was to investigate the correlation between gastric emptying measured by ultrasonography and Korean medical instruments of diagnosis and assessment in functional dyspepsia (FD) patients. Among the subgroups of FD, postprandial distress syndrome (PDS) is related to gastric motility disorder.Methods Ten patients with FD and particularly with PDS as well as 10 healthy controls were enrolled in the study from September to November 2015. The gastric emptying shown as the half-life of gastric volume (T_1/2) was measured by ultrasonography. The severities of spleen qi deficiency and dyspepsia symptoms were assessed by a spleen qi deficiency questionnaire (SQDQ) and the Nepean Dyspepsia Index-Korean version (NDI-K), respectively. In addition, a food retention questionnaire (FRQ), a damum questionnaire (DQ), a cold and heat questionnaire (CHQ), a deficiency and excess questionnaire (DEQ), and a visual analogue scale (VAS) of distention and fullness were completed by every participant.Results In comparison with the control group, the FD group showed significantly higher scores for the SQDQ, NDI-K, FRQ, DQ, DEQ, and VAS of distention and fullness. T_1/2 was also significantly higher in the FD group than in the control group. There were significant correlations between T_1/2 and the SQDQ score. However, there were no significant correlations between T1/2 and other questionnaire scores except for one item of the NDI-K.Conclusions According to these findings, it was determined that measuring gastric emptying using ultrasonography could be a quantitative indicator to diagnose spleen qi deficiency in FD patients.

The purpose of this study was to measure and investigate the acute effects of two fatty meals (high-SFA & high-PUFA) on post-prandial thermic effect, substrate oxidation, and satiety. Eight healthy adults (four males and four females) aged 19-22 years were assigned to consume two isocaloric meals: high in saturated fatty acids from butter and high in polyunsaturated fatty acids from sesame oil. Indirect calorimetry was used to measure resting energy expenditure (REE), post-prandial energy expenditure for five hours, and substrate oxidation. Satiety of the subjects after meals was estimated by using visual analogue scales (VAS). Five hours thermic effect of food (TEF) was not significantly different between butter meal (6.5% of energy intake) and sesame oil meal (7.3% of energy intake), but, the TEF of butter meal reached the peak point at 150 min and decreased more rapidly arriving to REE in 270 min. On the other hand, TEF of sesame oil meal reached the peak at 90 min and decreased slower than butter meal (still higher than REE at 300 min). No significant differences in substrate oxidation rates were found between the two meals. Post-prandial fat oxidation rates increased significantly after the consumption of both butter and sesame oil meal than that of the pre-prandial state. Satiety values (hunger, fullness, and appetite) were similar among the meals, but recovery of hunger and fullness to the pre-prandial state was faster in butter meal than that of the sesame oil meal.

Objective : Describe the phenomenon of "clear qi below, turbid qi above" as found in the Somun Eumyangeungsangdaelon (Major Essay on Yinyang Resonances and Appearances 素問 陰陽應象大論) and compare this pattern with water-grain dysentery and flatulence symptom patterns in the Sanghallon (Treatise on Cold Damage). Method : Study the annotation of the Hwangjenaegyeong (Yellow Emperor's Internal Classic 黃帝內經) and compare the results with the Sanghallon's water-grain dysentery and flatulence. Conclusions and Results : The causes of water-grain dysentery and flatulence are associated with the ascending and descending properties of Yin and Yang. Additionally, these symptoms can also be caused by pathogenic heat, turbid pathogenic factors, and interruption of the movement of clear and turbid qi. Aspects of water-grain dysentery resemble several patterns found in the Sanghallon. If caused by a weakness of yang qi, it resembles Sayeoktang (四逆湯) syndrome. Weakness of spleen qi resembles Ijungtang (理中湯) syndrome. Flatulence is similar to fullness in the chest syndrome, which in the Sanghallon is caused by an obstruction of cold qi. If there is excessive cold, water-grain dysentery is similar to the syndrome of Gyeolhyung (結胸). If the qi is not scattered, deficiency syndrome is similar to Gyejigejagyaktang (桂枝去芍藥湯) syndrome and excess syndrome is similar to Mahwangtang (麻黃湯) syndrome. When flatulence is caused by fever in chest, it is similar to Chijasitang (梔子?湯) syndrome. When caused by heat and phlegm build up in chest, it is similar to Sipjotang (十棗湯) syndrome.

Objectives : Symptoms caused by traffic accidents can be divided into localized pain and systemic symptoms. Edema and pain can be increased due to obesity. During hospitalization of obese patients after traffic accident injury, obesity and systemic symptoms such as edema, dizziness, abdominal fullness and heavy body feeling might increase more by decreased physical activity due to pain. Methods : This report details on two cases of obese female inpatients with systemic symptoms after a car accident who were treated with wild ginseng complex (WGC) pharmacopuncture combined with Korean Medicine (KM) automobile insurance treatment. The Numeric Rating Scale (NRS), Neck Disablility Index (NDI) and the Oswestry Disablility Index (ODI) were evaluated before and after treatment for comparison. Body composition was also measured. Results : Localized pain improved with a decrease in patients' NRS, NDI and ODI scores. Systemic symptoms increased during hospitalization were also improved with changes of body composition. Conclusions : Combining WGC pharmacopuncture with KM automobile insurance treatment may be synergistically effective for the treatment of obese patients with systemic symptoms such as edema, heavy body feeling and abdominal fullness.

Objectives: The purpose of this study was to investigate the opinions of experts on abdominal examinations in Korean Medicine included in the curriculum of the College of Korean Medicine. Methods: Among Korean doctors, 14 experts on abdominal examinations were interviewed; the experts included 9 professors of Korean internal medicine, 1 expert in diagnostics of Korean Medicine, 1 primary care Korean medicine doctor, and 3 executives of a (former) Korean association of the abdomen. The interview consisted of questions regarding recognition of the clinical importance of abdominal examinations, how to perform abdominal examinations, the most frequent abdominal examination findings encountered in clinical practice, and the definition of some of the abdominal examination findings. Results: Most interviewees recognized abdominal examinations as important and used them in clinical practice. Opinions on additions and corrections were collected regarding observation items, posture, method, and order during abdominal examinations. Abdominal examination findings that were common clinically were abdominal fullness (腹滿), epigastric stuffness (心下痞鞕), abdominal tenderness, epigastric fullness (心下滿), and rib distention (胸脇苦滿). The answers to the question related to the definitions of abdominal examination findings included consent and supplementary opinions regarding definitions of deficiency-excess, cold-heat, abdominal tenderness, tension of abdominal muscles, succession sounds, and borborygmus; these were mainly selected based on abdominal symptoms that are highly quantifiable. Conclusions: In the future, based on the results of this study, additional research related to the drafting of a standard abdominal examination in Korean medicine should be conducted to provide an opportunity to increase the reliability of Korean medicine diagnosis.
