Objectives ; Sasang Constitional Medicine is a part of Korean traditional Medicine, and classify human constitution into four types. Scalp and hair is a part of skin. Skin is one of constitutional charasteristic element. So we researched a correlation between Sasang constitutions and Korean adult scalp and hair condition. This is a basic study to find constitution can be a important factor to care scalp and hair. Methods ; We examined Sasang constitutions and scalp and hair condition of 80 human who aged from 20-50. Scalp disease, dandruff was observed by video micro scope and sebum tape diagnosis. Thickness of hair was measured by Laser Scan Micrometer(LSM-3100). Itching sense and life habit was also investigated. Constitution diagnosis and scalp, hair diagnosis was investigated seperately as a blind test and the data was statistically analyzed with chi-square test, correlation analysis, one-way analysis of varience. Results ; 1. In Sasang Constitution, Taeumin group had significant tendency of oilily scalp. 70% of Taeumin group had oilily scalp. 2. The group of dry or oilily scalp had more itching sense and more sensativity of scalp compaired to neuter scalp group. 3. There was no correlation between height, weight, thickness of hair, itching sense, scalp disease and Sasang constitution. 4. There was correlation between loss of hair and drinking alcohol, obesity, curly hair, soft scalp. Conclusions ; Korean adult scalp and hair condition had correlation with Sasang constitution.

This study aimed to investigate bag purchase behaviors according to materialism value. The subjects were 443 male and female adult consumers in their 20s to 50s. The research method was a survey, and the questionnaire consisted of questions on materialism value, bag purchase behaviors, and demographic characteristics. For data analysis, descriptive statistics, Cronbach's α, χ² test, factor analysis, cluster analysis, ANOVA, and Duncan's multiple range test were performed. The results of this study were as follows. First, materialism value was derived from three factors (happiness pursuit, possession-oriented, and success judgment). Second, subjects could be divided into three groups (happiness pursuit group, success judgment pursuit group, and immaterialism group) based on the materialism value variable. Third, the derived groups showed many differences in bag purchase behaviors. The happiness pursuit group considered all bag evaluation criteria factors (practicality, aesthetics, economy, symbolism) and bag purchasing information sources factors (mass media and personal sources) more than other groups, and showed a tendency to prefer select shops and complex shopping malls as bag purchasing places. In addition, the average annual cost and frequency of purchasing bags of this group were higher than those of other groups. The success judgment pursuit group considered symbolism as a bag evaluation criteria more than other groups, and considered personal sources as bag purchasing information sources more than mass media sources, and preferred luxury stores and department stores as bag purchasing places. On the other hand, the immaterialism group considered practicality and aesthetics as bag evaluation criteria and placed less importance on all information sources than other groups, and preferred Internet shopping malls as purchasing places. This group had the lowest average annual purchase cost and frequency among the three consumer groups. This study suggested that materialism value is a useful variable to segment male and female adult consumer markets effectively, and to understand the bag purchase behaviors of consumer groups divided by materialism value.

Background: Delayed sternal closure (DSC) is a useful option for patients with intractable bleeding and hemodynamic instability due to prolonged cardiopulmonary bypass and a preoperative bleeding tendency. Vacuum-assisted closure (VAC) has been widely used for sternal wound problems, but only rarely for DSC, and its efficacy for mediastinal drainage immediately after cardiac surgery has not been well established. Therefore, we evaluated the usefulness of DSC using VAC in adult cardiac surgery. Methods: We analyzed 33 patients who underwent DSC using VAC from January 2017 to July 2022. After packing sterile gauze around the heart surface and great vessels, VAC was applied directly without sternal self-retaining retractors and mediastinal drain tubes. Results: Twenty-one patients (63.6%) underwent emergency surgery for conditions including type A acute aortic dissection (n=13), and 8 patients (24.2%) received postoperative extracorporeal membrane oxygenation support. Intractable bleeding (n=25) was the most common reason for an open sternum. The median duration of open sternum was 2 days (interquartile range [25th-75th pertentiles], 2-3.25 days) and 9 patients underwent VAC application more than once. The overall in-hospital mortality rate was 27.3%. Superficial wound problems occurred in 10 patients (30.3%), and there were no deep sternal wound infections. Conclusion: For patients with an open sternum, VAC alone, which is effective for mediastinal drainage and cardiac decompression, had an acceptable superficial wound infection rate and no deep sternal wound infections. In adult cardiac surgery, DSC using VAC may be useful in patients with intractable bleeding or unstable hemodynamics with myocardial edema.

This study was performed to investigate the effect of breakfast regularity on eating habits, nutritional and health status in adult men and women. Also, eating habites and nutritional status expressed as percentage of recommended energy intake in IB(Irregular Breakfast group) were studied. Proportions of IB in men and women was 23.7% and 31.1%, respectively. In men, IB had irregular mealtime, overeating tendency. Also, they consumed high-fat meat and alcohol more frequently than RB (Regular Breakfast group). Total energy intake showed no significant difference between which two groups. Energy intakes from dinner and alcohol were higher in IB than in RB. Nutrient and food intakes were lower in IB than in RB. Percent body fat of IB was higher than that of RB. Weight, triglyceride and prevalence of fatty liver were higher in IB than in RB. In women, IB had irregular mealtime, and overeating tendency. Also, they had more frequent eating out and alcohol consumption. Total energy intake was lower in IB than in RB. In men, nutrient and food intakes were lower in IB than in RB. But health status showed no significant differences between two groups. In men, energy intakes from alchol and dinner were higher in +RDA group(percentage to recommended energy > 125%) than in other groups of IB. But energy intake from carbohydrate was lower in +RDA group. -RDA group (percentage to recommended energy < 75%) had Ca and vitamin A intake less than RDA. In women, +RDA group had overeating tendency. Also, they had more frequent eating out, high-fat meat, and alcohol consumption than other groups of IB. Energy intakes from dinner, snack and fat were higher in +RDA group. But -RDA group had protein and vitamin A intake less than RDA. From our study, it seemed that breakfast irregularity led to undesirable eating habits and had relation with increase of percent body fat. Breakfast regularity seemed to be very important to maintain a nutritional balance.

Objectives : To evaluate the foot indices using dynamic and static checking on healthy adult people. Methods : Foot indices analysis was performed for 46 students. Static checking practiced for Foot Pressure(FP) and Toe Pressure Difference(TPD) and dynamic checking was used for Vertical Axis Angle(VAA). Results : On gender, there was generally no statical significant difference, except RFP(Right Foot Pressure). The RFP of male was bigger than that of female. On age, in addition, there was similar tendency, only RFP had a positive correlation (r=0.35, p<0.05). Comparing foot indices on right and left, we found TPD and VAA had a tendency of pronation on left, but FP had a opposite tendency. On consistency of each foot index, discrepancy between TPD and VAA (39.47%) was lesser than combination of the others. Conclusions : According to foot indices among 46 healthy student, we found out that there is partially correlation between dynamic and static checking. We hope that the data we found will contribute to standardization of podiatry indices which provide medical guidance for cure of foot disease, supporting further podiatry research.

The purpose of this study was to investigate the current status of metal pollution in the sediment from rivers, lakes, and streams in active gold mining districts in Ghana. Two hundred and fifty surface sediment samples from 99 locations were collected and analyzed for concentrations of As, Hg, Cr, Co, Cu, Fe, Zn, Pb, Cd, Ni, and Mn using inductively coupled plasma-mass spectroscopy (ICP-MS). Metal concentrations were then used to assess the human health risks to resident children and adults in central tendency exposure (CTE) and reasonable maximum exposure (RME) scenarios. The concentrations of Pb, Cd, and As were almost twice the threshold values established by the Hong Kong Interim Sediment Quality Guidelines (ISQG). Hg, Cu, and Cr concentrations in sediment were 14, 20, and 26 times higher than the Canadian Freshwater Sediment Guidelines for these elements. Also, the concentrations of Pb, Cu, Cr, and Hg were 3, 11, 12, and 16 times more than the Australian and New Zealand Environment and Conservation Council (ANZECC) sediment guideline values. The results of the human health risk assessment indicate that for ingestion of sediment under the central tendency exposure (CTE) scenario, the cancer risks for child and adult residents from exposure to As were $4.18{\times}10^{-6}$ and $1.84{\times}10^{-7}$, respectively. This suggests that up to 4 children out of one million equally exposed children would contract cancer if exposed continuously to As over 70 years (the assumed lifetime). The hazard index for child residents following exposure to Cr(VI) in the RME scenario was 4.2. This is greater than the United States Environmental Protection Agency (USEPA) threshold of 1, indicating that adverse health effects to children from exposure to Cr(VI) are possible. This study demonstrates the urgent need to control industrial emissions and the severe heavy metal pollution in gold mining environments.

Compulsive hoarding becomes a problem when the spaces hoarded items are stored in become unusable due to clutter, health, or safety issues. Our research purpose was to document relationships between two non-normative consumer behaviors (compulsive hoarding, compulsive buying tendency) and two shopping-related variables: hedonic shopping motives and emotional attachment to possessions with everyday consumers. As hedonic shopping motives have been related to compulsive buying, we predicted these motives (e.g., adventure, gratification, role, value, social, and idea) are related to compulsive buying. We also examined the relationship between compulsive buying and compulsive hoarding tendency and whether emotional attachment to possessions moderated this relationship. Participants were 280 undergraduate and graduate students attending a Midwestern university in the U.S. Regression analysis revealed the enhancing emotion motive (a combined motive of adventure and gratification) positively influenced compulsive buying whereas the value motive negatively influenced compulsive buying. All other hedonic shopping motives were non-significant. Participants who tended to buy compulsively were likely to hoard compulsively. This relationship, however, was moderated by participants' emotional attachment to possessions. Participants with high emotional attachment to possessions showed a higher level of hoarding behavior than those with low emotional attachment to possessions. However, the increase in hoarding tendency among participants with low emotional attachment to possessions was larger between those who were low in compulsive buying and those who were high in compulsive buying than the increase between these two groups among participants with high emotional attachment to possessions.
