The purpose of this study is to examine residents' perception and needs for storage according to the family life cycle. In order to achieve our goal, the questionnaire survey is used. We sample the questionnaire surveys of 250 apartment households in Seoul. The data collect by the questionnaire survey was analyzed by examining the frequency, percentage on the SPSS/PC+ Statistics package. The results of the study are obtained as follows: 1) In research on the actual storage condition, residents tend to feel constraint on storage of the season goods and the storage satisfaction on the service area is founded lowest. Therefore, it is needed more efficient space plan on the balcony storage and the interior storage for the season goods. 2) In research on the storage consciousness and attitude, residents tend to keep the goods of no use and prefer to arrange neatly rather than use conveniently. Therefore, it is needed more efficient space in the balcony for the storage of the goods of no use and the colsed furniture rather than the open furniture is suited for arrangement. 3) In research on the storage needs, needs for the built-in furniture in all family life cycle show highly and residents want to a space for the exclusive use of the storage. In a solution, we propose to equip with the interior storage and the exterior cooperative storage

In this study, experiments using bioelectronic signals and questionnaire surveys were carried out in learning conditions when temperatures changed from low- and high-uncomfortable to comfortable. As a result, the stress factor Photoplethysmography (PPG) decreased, while the Root Mean Square of Standard Deviation (RMSSD) of PPG increased when the indoor temperature was changed from low- or high-uncomfortable to comfortable. Additionally, the absolute power of the ${\alpha}$-wave in the brain increased. According to the analysis of the association between the questionnaire and bioelectronic signals, the standard deviation of the stress factor as measured by pulse was closely related to the result of the thermal sensation questionnaire. In addition, it was found that the concentration on studying improved under comfortable temperatures when compared to uncomfortable temperatures.

Background: C-arm fluoroscopy equipment is important for interventional pain management and can cause radiation injury to physicians and patients. We compared radiation safety education and efforts to reduce the radiation exposure of pain specialists. Methods: A survey of 49 pain specialists was conducted anonymously in 2016. The questionnaire had 16 questions. That questionnaire was about radiation safety knowledge and efforts to reduce exposure. We investigated the correlation between radiation safety education and efforts of radiation protection. We compared the results from 2016 and a published survey from 2011. Results: According to the 2016 survey, all respondents used C-arm fluoroscopy in pain interventions. Nineteen respondents (39%) had received radiation safety education. Physicians had insufficient knowledge about radiation safety. When the radiation safety education group and the non-education group are compared, there was no significant difference in efforts to reduce radiation exposure and radiation safety knowledge. When the 2011 and 2016 surveys were compared, the use of low dose mode (P = 0.000) and pulsed mode had increased significantly (P = 0.001). The number checking for damage to radiation protective garments (P = 0.000) and use of the dosimeter had also increased significantly (P = 0.009). But there was no significant difference in other efforts to reduce radiation exposure. Conclusions: Pain physicians seem to lack knowledge of radiation safety and the number of physicians receiving radiation safety education is low. According to this study, education does not lead to practice. Therefore, pain physicians should receive regular radiation safety education and the education should be mandatory.

Treatments of severely incurved toenails cause anatomical changes and cosmetic problems, even though they provide adequate symptom relief. Incurved toenail patients treated with a K-D$^{(R)}$ (S&C Biotech, Seoul, South Korea) the new device for correcting curved nail deformity were investigated retrospectively. This study surveyed 12 patients(18 cases) who had been treated for severe ingrown toenails using K-D$^{(R)}$ from May 2008 to March 2009, and examined their subjective satisfaction before and after the treatment. The average age of the participants was 39 (ranging from 27 to 52), and 8 of them were male and 4 female. The treatment was applied after the patients were given a thorough explanation about the tool and the treatment, and questionnaire surveys were conducted before the treatment and after 3 months on the average from the treatment. In the survey, the respondents were asked about pain, restriction on activities, and the selection of shoes. For each item, symptoms with a given point were presented, and the respondents' scores were compared between the surveys before and after the treatment. According to the results of the questionnaire survey, pain increased from 14 out of 40 before the treatment to 39 after, activity restriction increased from 11 to 30, and shoe selection increased from 20 to 30. The average total score increased from 45 to 98, and this suggests a considerable enhancement in the patients' subjective satisfaction. The average period of the application of K-D$^{(R)}$ was $20.3{\pm}9.4$ days, and in all the cases, ingrown toenails were corrected within three weeks.

Background: A laboratory where chemicals are handled can be considered a hazardous environment, and hence, prudent practices should be strictly enforced. If not, deadly accidents and incidents could occur due to a lack of safety practices and poor safety culture. The purpose of this study is to analyze the existing safety culture and propose potential recommendations to enhance the level of safety education in the chemical laboratories in the Western Province of Sri Lanka. Methods: A survey questionnaire was administered among the laboratory supervisors of the chemical laboratories in the Western Province of Sri Lanka in 2019. Results: Even though 80 surveys were distributed among prospective participants, only 46 surveys were submitted, which is 58% of the response rate. Most of the individuals who participated in the survey were females below 35 years old, and approximately 96% of the participants had at least one year of working experience in the same laboratory setting. The majority considered safety as an important factor that requires further improvements with third-party safety inspections; however, 54% of the respondents mentioned that those inspections were conducted by the employees from their laboratory. Conclusion: From the study, it has been discovered that employees have knowledge of safety culture to a certain extent. A significant percentage (83%) of participants believed that further safety measures are required for a safer laboratory. However, the study revealed that the attitudes of some employees should be changed to have a better safety culture. Hence the authors would like to suggest having annual training sessions and well-formulated safety policies to improve the safety culture.

The purpose of this study was to evaluate the effect of dietary education on improving preferences to Korean traditional foods in upper grades schoolchildren. The education group consisted of 184 children ($4^{th}$=65, $5^{th}$=50, $6^{th}$=69), while the control group consisted of 135 children ($4^{th}$=40, $5^{th}$=55, $6^{th}$=40). Each group was selected from a different school in Changwon. In the education group, 12 lessons were implemented using educational materials based on sensory education. For the evaluation, pre- and post-surveys were performed in each group using self-administered questionnaire surveys. Variables in the questionnaire consisted of self-efficacy, subjective norms, cognitive attitude, food neophobia scale, eating frequency, preference, intake experience, and nutrition knowledge. After education, the knowledge score improved significantly in both groups. However, self-efficacy (p<0.01), subjective norms (p<0.01), cognitive attitude (p<0.001) and food neophobia scale (p<0.001) changed significantly in only the education group. The intake frequency of Korean traditional foods did not significantly increase in either group. However, the preferences and intake experience of the foods, which were offered in class and school meals, changed significant in only the education group. In conclusion, dietary education based on sensory education may be useful for developing a positive eating attitude for Korean traditional foods in children.

A study was performed to develop as a screening tool the Simple Evaluation Questionnaire for Screening the Over-weight-type Dietary Pattern in 30 to 49 Year Old Adults. We used the data from the 30 to 49 year old subjects who participated in the three surveys - the health behavior survey, the dietary habit survey and the food intake survey - as the National Health and Nutrition Survey 1998. The 3,598 adults were classified into to two body fatness groups of normal (including underweight) and overweight (including obese) on the basis of their relative body weight (RBW) When comparing variables between the two groups, significant differences were found in gender, education, job, employment status, perceived health status, sadness / depression state, stress level, age, number of diseases, age when overweightedness started, maximum body weight, sleep length, drinking pattern (yes/no) , amount of alcoholic drinks, frequency of intoxication or drunkeness, amount of alcoholic drinks when drunk, intensity of exercise, frequency of exercise, exercise duration, skipped meals, small meals and drug supplements. In terms of food intake, there were significant differences in the daily food intake in terms of breakfast, dinner, daily kimchi and dairy products. In terms of mealtimes, we found differences in the amount of cooked rice at breakfast, kimchi at lunch, soup / kuk at dinner, fresh vegetables for snacks, fried foods for snacks between breakfast and lunch, and fruits /juices for snacks between lunch and dinner. After developing questions with indicators and analyzing the indicators by logistic regression analysis three times, we chose 10 questions for a simple evaluation of dietary patterns for the overweight-type category in order to give one point each. Among them we selected two questions to add one additional point and one question to add two additional points. The average scores of the overweight and normal groups, as shown by the developed questionnaire, were $5.97 \pm 2.36 \pm 7.36 \pm 2.21$, respectively. A score of seven points was selected as the cut-off point. We examined the sensitivity, specificity and positive predictive value of the questionnaire to the results of 67%, 59% and 62%, respectively.

Background : To study any interference of demonstrated in different patient satisfaction scores for the same questionnaires handled by hospital staff and by independent surveyors, respectively. Methods : This study included 728 subjects who were admitted to a university hospital from June 22 to July 1, 1999. The contents of the questionnaire were composed of six dimensions: hospital structure and process, staffs technical competence and humaneness, information & education and communication. Measurements were performed on a 5-score Likert scale. T-test and logistic regression analysis were also performed. Results : In an outpatient survey, satisfaction scores from a questionnaire delivered by hospital staff were significantly higher than independent surveyors for the dimension of communication, but no differences were shown among other dimensions. In an inpatient survey, satisfaction scores by hospital staff were higher for the process and communication dimensions(p<0.05). In particular, in both the inpatient and outpatient surveys, the difference of satisfaction scores for personnel items were significant between groups. After adjustment for age and sex those differences were significant between groups. Conclusion : To minimize the bias on questionnaire survey, the effects of personnel, who deliver and gather the questionnaire should be carefully considered in the evaluation of health service satisfaction.

Study Design: Prospective observational study. Purpose: To evaluate the disability domains relevant to Indian patients with low backache and propose a modified disability questionnaire for such patients. Overview of Literature: The Oswestry Disability Index (ODI) is a self-reported measurement tool that measures both pain and functional status and is used for evaluating disability caused by lower backache. Although ODI remains a good tool for disability assessment, from the Indian perspective questions related to weight lifting and sexual activity of ODI are questioned in some of the earlier studies. Activities of daily living in Indian patients vary substantially from those in other populations and include activities like bending forwards, sitting in floor and squatting which are not represented in the ODI. Methods: In this prospective observational study, a seven-step approach was used for the development of a questionnaire. Thirty patients were interviewed to identify the most challenging issue they faced while performing their daily activities (by free listing) and understand how important the questionnaire items were in terms of the standard ODI. Thus, a comprehensive disability questionnaire comprising 14 questions was developed and administered to 88 patients. Both qualitative (interviews) and quantitative methods (to establish the validity, reliability, and correlation with the Visual Analog Scale [VAS] and Rolland Morris disability questionnaire) were used to identify the 10 questions that best addressed the disability domains relevant to Indian patients. Results: According to free listing, four new questions pertaining to bending forward, sitting on the floor, walking on uneven surfaces, and work-related disabilities were included. In the second phase, wherein the questionnaire with 14 items was used, 56.8% patients did not answer the questions related to sexual activity, whereas 23.8% did not answer those related to walking on uneven surfaces. The modified questionnaire demonstrated good internal consistency (Cronbach's alpha=0.892) and correlation with the Rolland Morris questionnaire (Cronbach's alpha=0.850, p>0.05), as well as with the VAS score for disability (Cronbach's alpha=0.712, p>0.05) and pain (Cronbach's alpha=0.625, p>0.05). Conclusions: A modified disability questionnaire that was designed by adding two questions related to bending forward and work status and removing questions related to sexual activity and weight lifting or traveling (depending on the occupation) can help evaluate disability caused by back pain in Indian population.
