Although previous studies have emphasized factors affecting people's variety-seeking behavior, research has not been performed to examine the interaction effect of good-bad luck and embodied cognition (hand washing) on variety-seeking behavior. Experience of good and bad luck affects consumer information processing and hand washing is known to reverse the experience of luck. Understanding the interaction effect of good/bad luck and hand washing on variety seeking behavior will shed important light on consumer behavior including choice and product purchase. To do this, a study was performed to investigate the effects of good/bad luck priming and hand washing on variety seeking behavior. Participants were primed with good or bad luck and then were asked to either wash their hands or not. After that, they were led to choose yogurt for the next seven days and the dependent measure was the number of different tastes of yogurt participants picked up. An interaction effect of luck priming and hand washing was found. Results indicate that, in good luck condition, there was no difference in variety seeking behavior between hand washing participants and non-hand washing participants. However, in bad luck condition, hand washing participants chose less diverse tastes of yogurt than non-hand washing participants. Implications of the study findings for the field of consumer psychology and marketing are discussed.

The purpose of this study was to assess the hygiene status of 145 child-care foodservices, which were newly registered in the Center for the Children's Foodservice Management (CCFSM) in Changwon, Gyeongnam. Sanitary inspection checklist (40 food safety items) of Korea Food and Drug Administration (KFDA) was used by the CCFSM in Changwon, Gyeongnam. Average score from the total safety items in 145 child-care foodservices was 21.41 points out of 40 points. Score gaps between the lower group (71 foodservices, 13.92 points) and higher group (74 foodservices, 28.61 points) showed a significant difference (P<0.001). The top five priorities of sanitary measures needing corrective actions for child-care foodservices were as follows: 'provide hand washing and sanitizing tools, and supply manuals on how to wash hands properly', 'supply record form for access/inspection', 'conduct education for cooks on standards in the selection of sanitizer for raw vegetables and proper methods to wash and sanitize raw vegetables', 'provide a refrigerator and a freezer with installed thermometers and temperature record monitoring logs', 'encourage separation of contamination operating zone and clean zone or conduct training for cooks on ways to prevent cross-contamination by performing work separately by the hour'. For the higher group, most were national/public facilities (83.3%), whereas in the lower group, private facilities (62.1%) were more common than national/public ones (37.9%). Therefore, a significant difference (P<0.001) was detected in the two groups. These private facilities should be supported.

The most desirable diesel oxidation catalyst (DOC) should have the properties of oxidibing CO and HC effectively at low exhaust gas temperature while minimizing the formation of sulfate at high exhaust gas temperature. Precious metals such as platinum and palladium have been known to be sufficiently active for oxidizing CO and HC and also to have high activity for the oxidation of sulfur dioxide (SO2) to sulfor trioxide (SO3). There is a need to develop a highly selective catalyst which can promote the oxidation of CO and HC efficiently, but, on the other hand, suppress the oxidation of SO2. One approach to solve this problem is to load a base metal such as vanadium in Pt-based catalyst to suppress sulfate formation. In this study, a Pt-V catalyst was prepared by impregnating platinum and vanadium onto a Ti-Si wash coated catalyst in a laboratory reactor by changing the formulations and reaction temperatures.

Effect of fixation methods on the flame retardant(FR) and performance properties of MDPPA/HMM treated cotton fabrics were studied. Combination of three different fixation methods - premercerization, swelling agent treatment, pad dry cure fixation, and wet fixation - were applied to flame retardant finish of cotton with MDPPA/HMM. As a result, an increase in internal volume of cotton fiber by pre-mercerization and addition of swelling agent, and wet fixation increased %add-on of FR agent improving FR efficiency and wash fastness. Tensile strength of MDPPA/HMM treated cotton fabrics by wet fixation and swelling agent were slightly decreased, but that of premercerized cotton was improved. Wet fixated fabric showed lower bending rigidity and better compressional properties which improved fabric hand. Retention of swelling ability of cotton treated with MDPPA/HMM improved moisture absorption properties.

This study was conducted to evaluate the methods used in nursing procedures for infection control. Skilled nursing procedures are related to prevention of hospital infection. The sample consisted of 301 nurses’ response to the questionnaire. Data were collected from Feb. to March, 1993 from 35 hospitals located in five major cities. The findings of the study are as follows : 1) Rotatively unsafe nursing procedures were reported for preperation of IV therapy, change of IV site and aseptic dressing on IV site, hand wash-ing and use of paper towels, use of sterile urine bottle with indwelling urinary catheter, management of dressing cart, disinfection of transfer forcep, ambu respirator, laryngoscope, humidifier and handling of incubator. 2) Relatively safe nursing procedures were reported for management of suction tube, marking for contaminated materials and waste collection. The rate of participation in education programs for infection control by the nurses was higher than in other research results. 3) Further study on procedures for IV site in-fusion and care of dressing cart are recommended.

Objectives: The purpose of this study was to investigate the association between practice and infectious diseases in elementary, middle and high school students. Methods: In 16 metropolitan cities and province of the Korea, the students who from fourth grade of elementary school to third grade of high school were surveyed by personal interviews and an web-based online survey from 5 to 25 September, 2014. We analyzed data with chi-square test and logistic regression analysis. Results: Common cold, diarrhea, and eye infections were more prevalent among students in higher grade than lower grade. In particular, common cold was more prevalent among girls than boys, using hand sanitizer than washing with soaps, and students who wash the dorsal side of hand than not wash the dorsal side of hand. Conclusions: Higher-grade students showed low status of hand washing practice. Hand washing was determined as the fact which influences to increase the prevention of communicable disease such as common cold. Considering the fact that youth groups have higher risk of being infected due to their group life, schools are recommended to provide adequate educations regarding proper hand washing practice with soap.

Purpose: To examine the effects on skin injury, pain, and anxiety when nurses and children simultaneous wash their hands before IV injections. Method: A nonequivalent control group, non-synchronized design study was used with 61 children. For a month and a half, children in the experimental group(30) following hand-washing guidelines, washed their hands with nurses before IV insertion. Anxiety and pain were observed and recorded during IV insertion using the Anxiety Reaction Scale and FACES pain scale. After 48-72 hours on IV therapy with an arm-board, skin condition was checked by a research assistant according to guidelines for assessing skin injury developed by the researcher. t-test, ${\chi}^2$-test, Pearson correlation, and Kendall's tau b were used to analyze data with the SPSS program. Results: Children who washed their hands with the nurse before IV insertion showed less pain (p =.021) and skin injury (p <.001) compared to the control group. Conclusion: This finding suggests that simultaneous hand washing by nurse and child before IV injection has a strong effect on skin injury caused by arm-boards used to maintain IV therapy as well as on pain during IV insertion. This program demonstrates an effective intervention to prevent skin injuries in children on IV therapy.

Most silk fabrics are produced only after the degumming process to make the best use of the properties and have restricted silk processing that do not hinder their performance. However, considering the highly increased preference for natural fibers and the shortage of raw silk, high-quality upgraded silk product functions are required by the development of a processing technology and a good design. This study analyzes the changes with the samples by the functional finish such as softening finishing, wash and wear, tannin weighting by measuring the objective hand of scoured silk and three finished ones using KES-FB. As a result, the change of objective hand of finished silk fabrics that improves functionality was analyzed and compared. The increase of KOSHI after the finish became stiffer show that the silk fabric samples are appropriate for summertime clothes with the retention of a certain clothing climate for the body. The stiffness of finished fabrics for the normal had a closer relationship with the density of fabrics than the type of finishing. The samples (after the softening finishes) maintain better elasticity according to the properties of the softener and the finishing agent. Although the specimens of this study were thin fabrics, their elasticity against compression increased after the softening finishes and became softer than degummed silk. The surface properties of georgette were changed by all types of finishing.
