We made a new sample design for intestinal parasitic infection survey in 2004. We used the 10% sample survey data of 2000 population and housing census as a survey population. Since the infection rates of intestinal parasitics are very low, we applied the relative risk and odds ratio instead of ordinary method such as t-test to study the characteristics from the 1997 survey data. In order to allocate samples to stratum, we used the compromise of Neyman allocation which is the average of three Neyman allocations. And also, we derive estimators and variance estimators of the estimators.

Objective: Objective of this study was to investigate community pharmacy-based pharmaceutical care accessibility in Korea. Survey on the current pharmaceutical care service provision was performed by PM2000 XE, a real-time pharmacy manager program, operated by Korea Pharmaceutical Information Center beginning November 4, 2013 until December 6, 2013 towards all community pharmacies throughout the nation which use the program. Method: The survey questionnaire consisted of four sections: pharmacy type, time-based accessibility, item-based accessibility, and spatial accessibility for non-prescription drugs. Results: Number of pharmacy responded to the survey was 331, and size of the responding pharmacy was mostly medium-scale (66.47%) with 30-99 prescription fillings a day. Proportion of pharmacy with opening hour of 12 hours or longer was only 53.77% and it was less than 25% during saturdays and holidays. Item-based accessibility was generally acceptable for prescription and non-prescription drugs, medical devices, and health supplements. However, spatial accessibility for non-prescription drugs was problematic because only one quarter of the drugs was displayed over the counter, and most of the drugs were behind the counter so that customers could not reach out. Conclusion: Based on the survey result, current situation for accessibility of pharmaceutical care service in Korea is concluded inadequate and therefore needs multidimensional efforts to improve accessibility of the service at national level such as Korea Pharmaceutical Association and Ministry of Health and Welfare.

This study aims to establish a strategy for selling kimchi to satisfy the needs and wants of European consumers through survey, FGI, and IDI. All survey participants were Europeans and were selected on the basis of their kimchi awareness. For the quantitative survey, 246 participants 15 years or older were selected; for FGI, 33 participants aged between 20 and 49 were selected; and for IDI, eight chefs were selected. The survey included four steps of 'Awareness-First try-Needs-Future consumption'. The participants got to know kimchi through the Internet; for example, by visiting Korea and Hallyu, and suggested positive comments, including 'fancy' and 'exotic.' While satisfaction with kimchi sharply decreased due to taste and appearance in the first try of kimchi, it is important to provide the best first-try experience. It also showed that important needs for kimchi are 'hot sensation', 'crunchiness' and 'presentation'. They gave a negative answer to combination with traditional cuisines of their own country, but provided positive comments for benchmarking the use of traditional pickled foods. This study suggests that it may be necessary to implement a two-track strategy by the traditional kimchi as a 'strategic product' and localized kimchi as a 'key product'.

The method of estimating a position using a GPS has been applied to various fields including a navigation system of an automobile. However, since it is difficult to measure GPS signals indoors, it is difficult to locate specific objects indoors such as a building or factory. To overcome these limitations, this study proposes a system for object location estimation based on Bluetooth5 for the management of materials in factories. The object position estimation system consists of a Bluetooth signal generator, a receiver, and a database server. A signal generator based on Bluetooth Low Energy(BLE) is attached to the material and a receiver is appropriately arranged inside the factory. In this study, we propose "Diagonal Survey Method", a 4 - axis survey algorithm using four receivers to reduce the error of existing trilateration method. The proposed algorithm showed good performance compared to the conventional trilateration and we verified the effectiveness of the proposed system and algorithm by performing the experiment by installing the system in the factory.

This research was done to gain the health information in one of the target areas(rural area) of the Korea University Community Health Project, and to improve and standardize the methodology of the health interview survey. There were two types of questions;one was the simple open-ended question and the other was check list in the interview survey for a total of 1,406 inhabitants. And so the result obtained from the above survey was analysed. The results as follows; 1) The morbidity rate in general was 11.2% by simple open-ended question and 32.5% by check list during recent 20 days in interview method. 2) Women had higher morbidity rate in both kinds of method. 3) The most prevalent diseases in the interview method using check list were the ones of the musculo-skeletal system and connective tissue (22.5%), and diseases of the respiratory system (19.8%) and digestive system (13.7%) were in order of frequency. 4) By the position in the family, housewives had highest morbidity rate in the interview method unrespectedly, and the reason seemed that the respondents were houseweives themselves and the morbidity rate was the one by spell not by person. But morbidity rate by the socio-economic status had no significant difference in both methods. 5) The agreement rate on simple open-ended question and check list was 72.5%, but if limiting respondents themselves only, the rate was falled to 54%. 6) The morbidities were diverse in the review of the results of previous morbidity surveies, but the morbidity rate was higher and less variable in case of using check list and getting the replies individually than using simple open-ended question and proxy respondents.

In this paper we consider an application of the method of electromagnetic (EM) migration to the interpretation of a typical marine controlled-source (MCSEM) survey consisting of a set of sea-bottom receivers and a moving electrical bipole transmitter. Three-dimensional interpretation of MCSEM data is a very challenging problem because of the enormous number of computations required in the case of the multi-transmitter and multi-receiver data acquisition systems used in these surveys. At the same time, we demonstrate that the MCSEM surveys with their dense system of transmitters and receivers are extremely well suited for application of the migration method. In order to speed up the computation of the migration field, we apply a fast form of integral equation (IE) solution based on the multigrid quasi-linear (MGQL) approximation which we have developed. The principles of migration imaging formulated in this paper are tested on a typical model of a sea-bottom petroleum reservoir.

The seismic vulnerability of Turkey is relatively high due to its active fault systems with potential to create destructive earthquakes. Thus, reducing the loss of life and property, the number of the earthquake-prone buildings and their retrofit requirements are considerably significant key issues under the scenario earthquakes. The street survey based rapid assessment (SSRA) method can be considered as a powerful tool to determine the seismic vulnerability of building stock of an earthquake-prone city/state. In this study, the seismic vulnerability of the building stock of the Kirikkale province in Turkey is aimed to be estimated adopting the street survey based rapid assessment method (SSRA). For this purpose, central 2074 existing reinforced concrete (R/C) buildings were structurally surveyed with rapid visual site screening and disadvantages such as, the existence of short-column, soft-story, heavy overhangs, pounding effect and local soil conditions were determined for obtaining the structural performance score of each. The results obtained from the study demonstrate that 11-25% of the surveyed buildings in the study region needs to be investigated through more advanced assessment methods. Besides, higher correlation between increasing story number and unsafe/safe building ratio is obtained for the buildings with soft-story parameter than that for those with heavy overhangs and short-column parameters. The conformity of the results of the current study with the previous documented cases of rapid assessment efforts in the recent earthquakes in Turkey shows that the SSRA method for the Kirikkale province performed well, and thus this methodology can be reliably used for similar settlement areas.
