The use of internet is expanding globally in a rapid way. The situation is similar in Korea. The growth of internet affects the various aspects of a social system. Such an impact is not an exception in the field of survey data-collection. The internet survey method has gained a recognition as an important survey approach in the U.S and Europe. A number of Korean research organizations have already started implementing the new survey method, too. The time is quite ripe for the internet survey in Korea. However, it is hard to find ever a good literature review on the subject. This study intends to review the results of the past studies about the question of what factors influence the response rate, speed, and quality. The influencing factors incorporated in this review include six elements: personalization, the survey sponsorship, incentives, the questionaire format, prenotification, and follow-ups. Regarding there sis factors, the results of the past studies relating to the internet survey response are reviewed in a systematic way.

Predicted noise level has been used to assess the annoyance response since noise map was generalized and being the normal method to assess the environmental noise. Unfortunately using predicted noise level to derive the annoyance prediction curve caused some problems. The data have to be grouped manually to use the annoyance prediction curve. The aim of this paper is to propose the method to handle the predicted noise level and the survey data for annoyance prediction curve. This paper used the percentage of persons annoyed(%A) and the percentage of persons highly annoyed as the descriptor of noise annoyance in a population. The logistic regression method was used for deriving annoyance prediction curve. It is concluded that the method of dichotomizing data and logistic regression was suitable to handle the predicted noise level and survey data.

Introduction of BIM(Building Information Modeling) was led by public institutions, and all buildings over a certain size were obligated to apply BIM. However, through various attempt to apply BIM to actual practice, people had doubt whether it is a usable technology in reality appeared. Therefore, this study investigated cases about implementation strategies of foreign countries, and conducted survey on BIM performances and preparation in architectural design firms. On the basis of this, it suggests the long-term development strategy of BIM and the basic direction of road map to adopt BIM effectively to domestic architectural design market. After considering the cases abroad and the results of survey, it is identified that incentive policies supporting finance and education should be carried out together with partially obligation method led by government in order to introduce BIM into architectural design market effectively by reflecting current situation of architectural design firms.

Inventory survey is process collecting data about cut slope. It's different from inspection. It contains not only basic information about cut slope, especially location, GPS positioning, height, length, weathering, joint direction, water conditions but also level of danger and damage. Collected data are being used get at status about cut slope along national roads. And It helps judging about priority of detailed investigation. According to results of analysis, we found better method about maintenance of cut slope. Later on, if inventory research is finished, we will understand characteristics of collapse slopes.

This is a survey of the circulation system for students in college & university libraries in Korea. The survey used a questionnaire with 14 questions on 6 items concerning the various aspects of the circulation system in 82 libraries responded among 85 college & university libraries as of 1981. The survey results discovered many problems needing improvement. The following list describes the measures needed to better the problems found in the survey results of 82 libraries. 1. 67.1% of the libraries shows the restricted volumes loaning less than 2 volumes, and 81.7% of the libraries shows the loan periods less than a week, but it is desirable to extend them, when comparing with the size of holdings and the higher educational system at present. 2. It is desirable that the number of a staff in charge of circulation works places one person per average 75-85 books borrowed a day, when calculating an adequate number of the staff on the basis of the correlation between books borrowed a day and number of the staff. 3. 59.8% of the libraries does not have reserved book system, but it is desirable to take it for increasing reliability about the circulation services. 4. More than half of the libraries takes a method of a public announcement on a notice-board for claims of overdue books, but it is desirable to send a claim notice to the individual in viewpoint of keeping their privacies. 5. More than half of the libraries to take the open access system uses a call slip, but it is desirable not to use it in viewpoint of simplicity and economical efficiency of the charging system, because of demanding the unnecessary records. 6. Most of libraries shows many problems of the charging system, especially in factors of the records and filing system, but it is desirable to improve it on the basis of 4 basic factors of the charging system, that is, simplicity, economical efficiency, promptitude and accuracy.

Geophysical survey was carried out to derive some information on the existence of near-surface anomalous body at Reung-Chi area in Kongju. Resistivity, seismic, magnetic and gravity method were applied. Geophysical survey that was applied was the electrical resistivity survey, seismic survey, magnetic survey, gravity survey. These surveys are analyzed to provide data of high resolution. As a result of analysis of resistivity survey, anomalies showing high resistivity anomaly than around appeared, and the one showing M-shape out of those explains the possibility that underground common or other underground structure or geographical anomalous zone could exist in the underground. As a result of analysis of seismic survey, it is clear that the low velocity layer is spread as far as the bottom of the underground. It is possible to presume that it is a phenomenon appearing while going through the underground space where it is lying in the underground. Area that shows unusual situation in interpretation of data on seismic waves are included into the area that once showed resistivity anomaly, the results of both seismic surveys come in accord. As a result of magnetic survey, a circle-shape of twin magnetic fields in the area where abnormalities are shown between electrical resistivity survey and seismic survey is appeared. Given the area of gravity survey, abnormalities whose density is different from the one around the bottom of the underground. As a result of analogizing the data of underground of the subsurface based on analysis of data from each survey, it was interpreted that anomalous zone exists commonly in the research areas.

Purpose: The purpose of this study is to provide reference points for the improvement work of churches' convenience facilities for the elderly. To do this, the study generates survey results, showing that the perception to significance of churches' convenience facilities is different among survey constituents. Method: The survey method was utilized. The study population for survey includes the aged believer over 65 years old, pastors, and architecture and/or interior design experts. The questionnaire was devised while consulting existing regulations regarding convenience facilities in general. Results: It is found that the perception to significance of installation standards for convenience facilities is different among survey constituents. Specifically, while the older believer group is perceived that installation standards for the small group meeting room of 'other facility' is comparatively more important, the pastor group and the expert group perceive that the 'intermediate facility' and 'inner facility' are more important. Implications: Participants involved in an improvement project of churches' convenience facilities may have a different perception about their importance due mainly to the degree of usage and the difference of perspectives. This study, therefore, can be used as a reference point for prioritizing improvement works of churches' convenience facilities for the elderly.

It is difficult to obtain the population information of target variables when a new sampling design for successive survey is executed. In a research of the Korea National Tourism Survey, we propose a method for selection of efficient stratification variables which are found in a combination of a existing sample data and a new frame list. At first, if there isn't common identification number between the frame list and the sample data, we find a device to substitute for absence of identification number. At second, we suggest a method to search stratification variables correlated with target variables using statistical methods like regression analysis.

In this paper, we place the focus on suggesting a method of forecasting demand for PCS resale service with survey data in Korea. It is important for the service provider to forecast the diffusion process when designing marketing strategies and analyzing the costs and benefits. For the reason, we conduct a survey of three groups composed of non-subscribers, cellular subscribers, and PCS subscribers in order to forecast the demand according to several possible scenarios and business strategies. We consider the survey item that is measured by multiple point scales in response to a question if he would subscribe to the mobile telephone service in the future. We propose a method to forecast the size of market potential by classifying each individual into the two extreme groups, that is, yes or no. Then, by integrating survey data and historical data, we forecast the demand for PCS resale service that varies according to scenarios and strategies. From the results, we can find several implications for the provider of PCS resale service.

Though an internet survey, an alternative method for the off-line survey, has various merits is, it still has some problems such as sampling bias and low reliability from insincerity during survey. Especially the exogenous variables such as sample respondents of the environment should be controlled to make internet survey trustworthy. This study attempts to design and implement such system that can help researchers to control the network and sampling environment and behaviors on respondents. Thru the various Question forms and structured Questionnaire design, this study tries to contribute the improvement of survey satisfaction and the reliability for survey result in internet survey system.
