There is an increasing need to use mobile Internet as a research tool as wireless technology has been developing rapidly. However, little research has been conducted to confirm methodological validity of mobile Internet survey. This study examines the possibility of using mobile Internet as a survey tool by comparing survey results of mobile and stationary Internet surveys with the same questionnaire. The results were analyzed from both economic and theoretical perspectives. Both mobile and stationary Internet survey sites were implemented with supports from domestic mobile and stationary Internet portals and telecommunication companies. The results show that there exist several differences between two survey methods. First, many respondents who use mobile Internet gave up at the early stage. However, once people continued to respond, they answered the questions to the end. Second, means and standard deviations of mobile internet respondents were higher than that of stationary Internet. Third, the results of two survey methods were significantly different by comparing construct validity that includes both discriminant validity and convergent validity. Finally, this paper ends with implications and limitations of using mobile Internet as a survey tool.

Subjective evaluation has always been regarded as a branch of social science research. Hence, in scientific and especially engineering points of view, its development is always taken for granted despite the importance of its effects on the design and development decisions. In the past, at least two automotive seat survey questionnaires have been developed with high statistical validity and reliability. Nonetheless, both were not local while subjective perception very much depends on demographic background factors. It is felt that since vehicle seat comfort is an important aspect in a seat design, a local sense should be put into the survey that is used as the subjective tool. The proposed vehicle seat discomfort survey questionnaire was developed in dual languages; English and Malay. Malay language is the national language of Malaysia, where the survey was tested. Beside inputs from literatures, key informant interviews helped in establishing the appropriate terms used as survey items. Three experimental runs on two different seats by 22 paid subjects showed that the developed questionnaire is reliable and valid. Furthermore, criterion validity analysis on the survey and previously developed survey showed significant correlation at 0.01 significance level.

In case of executing surveys in marine ecosystems, the most important things are scientific selection measures of survey stations that can represent various ecosystems characteristics in subjected areas. The situations show a lot of differences that understand characteristics of marine ecosystems in targeted areas according to selection methods and positions in survey stations. Investigation ranges and station numbers in marine ecosystems are classified according to project characteristics and scales. But, currently a clear divisions or objective standards are not. Therefore, this study tried to provide selection measures of survey station in scientific and objective marine ecosystems through precise analysis among environmental impact statements of coastal development projects until now. In this study, impact scopes of marine ecosystems correspond to physical impact predictions by undertaking projects. Impact ranges were divided into three(physical impact ranges) coastal waters. In case of proposing numbers of survey stations according to this survey ranges, numbers of investigation stations due to minimum survey scopes in targeted projects applied 20~30% of all numbers in survey stations. Number of survey stations due to average investigation scopes within physical impact ranges applied 60~70% of all numbers in investigation stations. Numbers of survey stations due to maximum survey ranges within physical impact scopes applied 10~20% of all numbers in survey stations. So, improvement measures were deducted. Finally, according to prediction ranges in impact of various coastal development projects, several kinds of conclusions are suggested. And, it is thought to be able to use as fundamental database to select investigation stations in marine organisms through this study.

인터넷을 이용한 여론조사가 늘고 있다. 그러나 연구자들은 인터넷 조사의 편리성과 실용성 등은 공감하면서도, 인터넷 샘플이 일반 모집단 샘플과는 차이가 있으며 그로 인해 조사의 정확성을 해친다고 보고 있다. 이에 대한 의결방안으로 서로 다른 조사방법을 결합하여 분석하거나 가중치를 두어 표본 편향을 제거하는 방안이 제시되고 있지만 아직 뚜렷한 연구 성과를 얻지는 못하고 있다. 본 논문에서는 응답패널을 미리 구성하여 실시하는 여론조사의 경우로 한정하여 이러한 인터넷 여론조사가 갖는 정확성의 정도를 살펴보았다. 그리고 이러한 인터넷 여론조사의 정확도 수준을 결정짓는 주요한 요인이 무엇인지, 그리고 인터넷 여론조사가 다른 조사방법에 비해 부정확하다면 그 요인은 무엇인지도 분석해 보았다. 이를 위해 본 연구는 17대 총선기간의 인터넷 조사, 유선조사, 모바일 조사 간의 결과를 비교하여 그 차이를 살펴보고, 이들 결과를 실제 총선 결과와 비교 분석하였다. 분석 결과 인터넷 조사의 정확도는 유선조사와는 비슷한 수준이나 모바일 조사보다는 좀 더 높은 것으로 나타났다. 인터넷 패널의 정확도에 관련된 요인으로는 첫째 패널이 자발적 참여자로 구성된다는 점이었다. 인터넷 패널은 전화조사보다 자발성이 높은 응답자로 구성되어 있고, 이러한 자발성 편향은 조사 결과에 영향을 미친다. 둘째로 인터넷 조사 패널은 재택시간에 관계없이 조사에 참여할 수 있다는 점이 전화조사보다 더 정확해 질 수 있는 요인으로 작용한다. 셋째로 인터넷 패널은 교육수준에서 편향을 보이고 있다. 패널을 이용한 인터넷 조사는 무응답률이 낮고 응답의 신뢰성이 높다. 인터넷 패널 특성에 대한 이러한 연구는 인터넷 여론조사의 정확성과 유용성을 높이는데 기여할 것이다.

The purpose of this study was to compare the difference of two survey methods for health services research. Data were collected by means of two types of household survey conducted from March 11 to September 19, 1985. A probability sample of 30,613 persons was taken from 180 Enumerated Districts designated by the Economic Planning Board. The sample was divided into two groups systematically. One group was surveyed by the self-administered questionnaire and the other group was interviewed. Response rates were 81.4% and 90.6% respectively. The data were analysed by the ratio of the results of the self-administered survey to those of the interview survey. No difference was observed in sex, age, residence, or occupation between the two groups. However the respondents' characteristics were statistically different between the two groups. The major findings of this study are as follows : 1. The morbidity rate was 142.5 per 1,000 persons during the two week period by the self-administered questionnaire survey and 74.3 per 1,000 persons with the interview survey method. The ratio of the morbidity rate by the self-administered questionnaire to that by the interview was 1.92, and the difference between the two rates were due to the personal characteristics. 2. The out-patient utilization rate was 10.2 visits per person per year by the self-administered questionnaire survey and 5.4 by the interview survey, and the ratio was 1.89; the admission rate was 3.2 times per 100 persons per year by the self-administered questionnaire survey and 1.9 times by the interview survey, and the ratio was 1.68. Differences due to the sociodemographic characteristics were greater in the out-patient utilization rates than in the adimssion rates. 3. Percentages of effective medical care demand were 90.2% in the self-administered survey and 92.3% in the interview survey; the ratio was 0.98 which was less than that of the morbidity rate and medical care utilization. But, differences of effective medical care demand occurred in persons with no occupation, and aged or low educated respondents. 4. Respiratory illness had the highest frequency in the two survey methods. But there was a slight difference between the two survey methods in morbidity composition. 5. It was concluded that data collected by the interview survey were inclined to be underestimated and this problem can be corrected by a modified self-administered survey.
