Objectives : The purpose of this study was to reveal the prevalence of Mibyeong and its symptoms including fatigue, pain, sleep disturbance, dyspepsia, depression, anxiety and anger by using the national survey. Methods : Questionnaires were collected by Gallup Korea. Participants were chosen through stratified sampling method based on area, gender and age. Questionnaire was designated to confirm the recognition, managing of Mibyeong, investigation of life habit, medical history, basic information, QoL questionnaires (Short Form-12, EuroQol-5D) and understanding of Mibyeong medical service conditions. Generally all questionnaires were used for survey the Mibyeong status in public except QoL questionnaires. Questionnaires were fulfilled by professional surveyor as face to face interview. Descriptives was used for data analysis and the results were expressed as percentage ratios (%) Results : 1,101 of people were acquired in this study. Eighty point two (80.2%) percent of participants did not know the concept of Mibyeong accurately even though 80.6% complained of Mibyeong related symptoms. Among them, fatigue was accounted for the highest response (70.7%)in this study. Sixty point four percent of participants identified non-smoking, stop drinking, eating habits and sleeping habits as a way to manage their Mibyeong related symptoms. In addition, exercising (60.8%), visiting medical institution (58.4%) and taking health functional food (52.7%) were presented. Only 23.1% among people with symptoms Mibyeong visited medical facilities. Moreover, the quality of life was found to be significantly correlated with health status. Conclusions : This study could contribute to express the importance of announcing the concept of Mibyeong and status to Korean public. Moreover, more Mibyeong studies should be conducted in the future to evaluate the Mibyeong status objectively.

We had a full scale of literature survey and case survey of mathematics Flipped Learning class models. The purpose of this study is to design and adopt a Flipped Learning 'Linear Algebra' class model that fis our need. We applied our new model to 30 students at S University. Then we analyzed the activities and performance of students in this course. Our Flipped Learning 'Linear Algebra' teaching model is followed in 3 stages : The first stage involved the students viewing an online lecture as homework and participating free question-answer by themselves on Q&A before class, the second stage involved in-class learning which researcher solved the students' Q&A and highlighted the main ideas through the Point-Lecture, the third stage involved the students participating more advanced topic by themselves on Q&A and researcher (or peers) finalizing students' Q&A. According to the survey, the teaching model made a certain contribution not only to increase students' participation and interest, but also to improve their communication skill and self-directed learning skill in all classes and online. We used the Purposive Sampling from the obtained data. For the research's validity and reliability, we used the Content Validity and the Alternate-Form Method. We found several meaningful output from this analysis.

The housing market in Korea had mainly consisted of Maemae(purchasing market) and Chonsei(rental market). Since 1997 foreign exchange crisis, the rental housing market has experienced substantial changes in preferred rental contracts between Chonsei and monthly-rent. Even though monthly-rent has taken a substantial portion of housing rental contracts, not yet reliable monthly-rent index has been developed. Furthermore, it isn't obvious to define monthly-rent because there are many types of monthly rent structures from full-monthly-rent to monthly-rent-with-variable-deposit. This study is the basic research of developing a housing price index of monthly-rent in accordance with the existing price index of Maemae and Chonsei in Korea. This research has been carried out with the following contents: (1) Constructing the actually desirable concept of monthly-rent through examining monthly-rental market in Korea. (2) Selecting the reasonable method to investigate monthly-rental market, especially monthly-rent-with-variable -deposit. (3) Designing monthly-rental market samples and calculating the price index of monthly-rent based on 2005 Census.

This research intends to discover the housing conditions of the elderly in rural area in South Korea, and identify measures to improve the conditions for an independent and safe life of seniors. This research conducted both survey research and experimental study. The survey interviewed 1,000 elderly people over 65 in farming areas across the country based on random selection from Census 2010 and sampling by regional size and administrative unit (Eup, Myeon, Li) to reflect the regional characteristics more accurately. The data was analyzed using SPSS 18.0 program. The experimental study identified the housing elements that may threaten the life of seniors based on a complete survey on households of elderly people over 65 in a selected typical rural village. As a result, the most inconvenient and threatening factor in the housing facilities appears to be the floor level difference. It was identified that most houses had the risk of falling due to the differences of the floor level between indoor and outdoor, and slippery floor materials. The squat toilets also bring inconvenience not only to the seniors with limited mobility but also to healthy elderly people. In particular, as most bathroom doors opened inward, it may be difficult to escape from or rescue someone in an emergency of falling, fainting or exhaustion.

In this paper, we study a sample design for survey on goodwill in retail properties to provide a protecting policy for small traders and tenants, to use basic data for a dispute case related to goodwill. Since goodwill in retail properties is occurred by individual rent company, we use the census on establishments from the Statistics Korea as population. First of all, we consider preferentially seven metropolitan cities in which there are more than half of population. Total sample size is decided as 8,000. We allocate the sample size for markets as stratum in each city using proportional formula and the sample size for industrial classifications in each market using root proportional formula. Also we compute survey weights and calculate estimators, standard errors and interval of estimators for each characteristic such as type of establishments and market in seven metropolitan cities.

The purpose of this study was to provide the proper nutritional management, and help to improve the health of girl students in a rural area. The nutritional survey, and blood sampling was conducted for five days, from April 26 to 30, 1983. The subjects of this survey were 110 students of girl's high school in Cheongyang area. The results were summerized as follows; 1) The daily food intake was 842.3g and that of animal foods was 34.4g. The average intake of calorie, protein, Ca, Fe, thiamin, riboflavin and niacin except Vit. A and Vit. C was below the RDA. Total calorie intake was l,802kcal. The ratio of carbohydrate, protein and fat was 81:11:8. 2) The extent of malnutrition was explained in terms of the amount of calorie, protein, Ca, Fe, and Vit. C. The predicted percentage of deficiency was 47.3% in calorie, 46.4% in protein, 61.8% in Ca, 48.2% in Fe, and 15.5% in Vit C of total subjects. 3) The mean values of Hgb, Hct and MCHC were 13.15g/dl, 39.57% and 33.2%, thus, the anemic prevalences were 10.9%, 2% and 78.2% respectively. The mean values of SI.TIBCand TS were $109.86{\mu}g$/61, $317.11{\mu}g/dl$ and 34.59%. 4) The correlation between the economic levels and nutrients intake was significant. Correlation between weight and nutrients intake was also significant but nutrients intake was not significantly correlated to blood contents.

Objectives : The aim is to comprehend the difference of moxibustion used according to applied body parts (knee pain, neck pain, back pain) to oriental doctors running clinic in Seoul. Methods : A sampling of 288 oriental doctors running clinic in Seoul was done and the doctors were asked to fill out 20 questions by interviewing directly from Nov. 23. 2009 to Jan. 9. 2010. Results : The result shows that moxibustion was used for knee pain and back pain more than neck pain. The type of moxibustion mostly used was sticker moxibustion for all three symptoms. Burn marks were left mostly in knee and back pain. Most large volume of moxa was used to back pain. More than half of the oriental doctors used 1-3 acupoints for one procedure and on average 2-3 sessions was done. Patients with knee pain and back pain had more than 4 sessions compared to neck pain. Treatments were mostly done 3 times a week, and as for total treatment period, it took less than 1 week for acute symptom, and it took more than 1 week and less than 5 weeks for chronic symptom. Conclusions : This research shows that the method of moxibustion used differs according to the area of treatment(knee pain, neck pain, back pain) by survey of oriental doctors through direct interviews.

The purpose of this paper is to survey the current status of service utilization in oriental medicine, to identify the determinants of consumers' decision in the service utilization, and then suggest policy implications for promoting the consumers' utilization. A multiple regression model was adopted to analyze the factors that influence consumer's decision in purchasing the oriental medical services. Data used in this research relied on National Survey Data conducted by Korea Institute of Health and Social Affairs, and sampling survey. The results could be summarized as follows.: 1. the number of visits to oriental medical institutions has shown an overall increase during the last decade since the inception of health insurance for oriental medical services. It still, however, revealed a relatively iow figure to western medical services. 2. the main factors, after controlling demographic variables, that determine consumers' selection between oriental medical services and western medical services are considered to be price, belief in effectiveness of services, waiting time for service. Implications for policy recommendation include 1. to reduce a barrier to service utilization by discounting dramatically the price of herb medicine, which is believed to be crucial in expanding market share, 2. to encourage consumer's belief in clinical effectiveness through a specialization in competitive services compared with wertern medicine, 3. to keep the affirmative image among consumers alive through an active participation of oriental medical doctors in community activities, 4 to change the health care system in favor of oriental medicine in the long run.

The seawater in the Taean area was surveyed to evaluate the conditions of the bay and compliance with the bacteriological criteria for a designated area for shellfish production for export. Samples of seawater were collected monthly at 34 sampling stations established in the survey area from January 2002 to December 2004. The bacterial density in the coastal area close to a pollution source located to the northeast of the survey area was higher than in the open sea to the west. The bacteriological counts in the water did not change with 16.5mm of rainfall, but increased abruptly after 65.4mm of rainfall. The total coliform and fecal coliform most probable numbers (MPNs) of 1,224 seawater samples in the survey area were <1.8-2,400 and <1.8-790 MPN/100 mL, respectively. The geometric mean and estimated 90th percentile of total coliforms were 1.9-3.4 and 2.7-26.3 MPN/100mL, respectively, and for fecal coliforms were <1.8-2.6 and 1.8-12.0 MPN/100mL, respectively. The bacteriological water quality in the Taean seawater area met the National Shellfish Sanitation Program criteria for an approved area and the Korea Shellfish Sanitation Program criteria for a designated area for shellfish production for export.
