인터넷 서베이는 off-line 설문조사에 비하여 여러 가지 장점이 있으나, 그럼에도 불구하고 샘플링 오차, 인터넷 환경이 가져오는 설문상황에 따른 신뢰성 등의 중요한 고려사항이 발생한다. 특히 이러한 인터넷 환경이 야기하는 외부변수들을 통제하지 못하는 한, 인터넷을 통한 여러 사회연구는 그 적용가능성에 큰 허점을 나타낸다. 이같은 인터넷 설문조사의 단점을 보완하기 위해 본 논문은 리서처에게 다양한 옵션을 가능하게 하고, 사용자 환경을 컨트롤하는 시스템을 설계 구축하였으며, 특히 데이터 품질향상을 위한 대안적인 노력을 하였다. 본 연구의 결과 인터넷 설문조사는 그 응답품질이 매우 향상될 것으로 기대된다.

오늘날의 인터넷은 네티즌들에게 수많은 정보를 제공해 줌에 따라 이제는 본격적으로 인터넷을 통해 네티즌들의 생각을 수집해 가는 단계에 이르렀다. 이러한 상황에서 웹 설문조사는 오프라인뿐 만 아니라 온라인상에서 그 가치를 더 할 수 있다. 하지만 많은 사람들의 참여가 중요하기 때문에 설문조사는 사람들의 관심을 끌 수 있는 주제여야하고, 서술적인 평범한 화면보다는 가시적인 기능이 추가되어 흥미를 유발시키는 새로운 인터페이스를 제공해 줌으로서 네티즌의 보다 적극적인 관심과 설문조사에서의 높은 호응도를 이끌 수 있다고 본다. 이에 플래시를 이용한 웹 설문조사 시스템을 이용해서 재미있게 설문조사를 할 수 있게 함으로서 가치를 한층 더 높여 보고자 한다.

Purpose: The aim of this study was to investigate the current status of the use of neglect test tools and the awareness for egocentric neglect (EN) and allocentric neglect (AN). Methods: A survey questionnaire was distributed to occupational therapists attending continuing education at the Daegu-Gyeongbuk branch on April 16. A total 143 responses were collected, and with the exception of 5 incomplete responses, 138 of them were analyzed. Results: The most commonly used unilateral neglect test tools were the line bisection test (86 responses, 62.3%), cancellation test (35 responses, 25.4%), copy and drawing test (7 responses, 5.1%). In a follow-up survey of 86 respondents who used line bisection tests as the most commonly used test, the majority (82 responses, 95.3%2) were found to use the 20-line test paper. In question about the familiarity and education experience for test manual, only 20 responses (23.2%) and 3 responses (3.5%) answered 'Yes'. In a question about the experience of a manual and the article for the manual, 25 responses (29.1%) answered 'Yes'. In the question regarding the separation of EN and AN on the unilateral neglect test, 44 responses (31.9%) were 'distinction' and 94 responses (68.1%) were 'no distinction'. Conclusion: Information on the guidance and interpretation of the line bisection test is lacking and the concept of EN and AN was insufficient.

The purpose of this study is to proviede basic data for designing sports-brassiere by a questionnaire survey about sports-brassieres preferences and physiological wearing test. The results of the survey and the physiological wearing tests on sports-brassieres are as follow; 1. According to the survey, dissatisfied factors on the sports-brassiere are "drooping and vibrating of the breasts". Preferable factors are supporting breasts by stretch and seldom changing its position by motion. The bigger cup-size and more hemispherical-type causes more discontent than flat-type. 2. The shape of breasts is oval, on what ground, horizontal line is longer than vertical. For the cross section of bust line, shirts type.brassiere is more gently curved than cup-brassiere. 3. The feeling of wearing comfort is correlated with bust.up, shield, close adhesion. The vibration of breasts is correlated with covering urea and close adhesion, and the changing band's position by movement, close adhesion. Too much covering area or strain are in inverse correlation of the comfort. 4. The rate of prevention of vibration is 75~80% on superior sports-brassieres, which has broad covering area and excellent close adhesion. adhesion.

Electromagnetic and electric surveys were performed to reveal the deep structure of the Yangsan fault in the Bong-gye and Unyang areas, Kyeongnam Province, Korea. Especially, high-frequency magnetotelluric (HFMT) method of EM survey was mainly employed to study the deep subsurface configuration of Yangsan fault. HFMT survey was performed at 25 points of spacing 50 m, making 1.3 km survey line in Unyang area and 13 points of spacing 50 m, making 0.6 km survey line in Bong-gye area. Two 2-D cross-sections (Unyang and Bong-gye areas) were achieved as results. Electric survey by dipole-dipole array was performed to study the structure of shallow subsurface and compare the results with HFMT surveys. The results of HFMT and electric surveys show that Yangsan fault is a geologic boundary. It is very narrow and steep (about $80^{\circ}C$), and extends to 1~1.5 km depth.

We present the discovery of rare active galactic nuclei (AGNs) in nearby (z<0.05) compact elliptical galaxies (cEs) located in isolated environments. Using spectroscopic data from the Sloan Digital Sky Survey (SDSS) Data Release 12, four AGNs were identified based on the optical emission-line diagnostic diagram. SDSS optical spectra of AGNs show the presence of distinct narrow-line emissions. Utilizing the black hole (BH) mass-stellar velocity dispersion scaling relation and the correlation between the narrow L([OIII])/L(Hβ) line ratio and the width of the broad Hα emission line, we estimated the BH masses of the cEs to be in the range of 7×10⁵-8×10⁷ solar mass. The observed surface brightness profiles of the cEs were fitted with a double Sérsic function using the Dark Energy Camera Legacy Survey r-band imaging data. Assuming the inner component as the bulge, the K-band bulge luminosity was also estimated from the corresponding Two Micron All Sky Survey images. We found that our cEs follow the observed BH mass-stellar velocity dispersion and BH mass-bulge luminosity scaling relations, albeit there was a large uncertainty in the derived BH mass of one cE. In view of the observational properties of BHs and those of the stellar populations of cEs, we discuss the proposition that cEs in isolated environments are bona fide low-mass early-type galaxies (i.e., a nature origin).

According to a simple survey on the current status of the assembly line design, it was found that trial and error methods on the basis of experiences have been used mainly in domestic manufacturing industries, even though there exist a lot of excellent line balancing studies. It seems that more practical researches should be carried out to develop user-oriented line balancing tools especially for small and medium-sized enterprises. This study presents a design of the line balancing tool which can support the line balancing tasks of nonspecialists. The proposed design tool is composed of three major modules: pre-process, line balancing, and post-process. In particular, pre-process and post-process are newly proposed to increase its ease of use. We applied the proposed design to a test problem and test result showed that our practical method may contribute to enhance the efficiency of production operations management.

IKONOS image mapping is being considered a possible replacement to the traditional mapping in many countries due to their ease of access to current data and their potential high resolution. Survey Department of His Majesty's Government completed traditional orthophoto mapping of all urban and semi-urban areas of the country. The 1:5000 monochrome orthophoto maps of Kathmandu Valley were completed in 2003. In 2002, as a test, production of a near natural colour Image Map at 1:5000 scale of a part of Kathmandu Valley based on IKONOS data was carried out. A conventional line map plotting of the same area at 1:5000 was also prepared. The objective of the pilot project was to assess the geometric accuracy and the information content of these maps. The details of the study and their results are underlined. The findings of the study helps to explain whether IKONOS image map can replace conventional orthophoto map at 1:5,000 for urban areas of Nepal like Kathmandu.

To understand the connection between active galactic nuclei (AGNs) and star formation, we investigated the relation between AGN bolometric and far-infrared (FIR) luminosities, using type-2 AGNs. By matching type-2 AGNs at z < 0.3 selected from the SDSS based on the emission-line diagnostics, against the AKARI/FIS All-Sky Survey Catalogue and the COSMOS PEP (PACS Evolutionary Probe) Survey Catalogue, we obtained a sample of 729 type-2 AGNs detected in the AKARI survey ($90{\mu}m$) and 17 ones detected in the PEP survey ($100{\mu}m$). For AGN bolometric luminosities, we adopted an estimate based on the [OIII] and [OI] line luminosities. We confirmed that there is a correlation between the AGN bolometric and FIR luminosities with a large scatter, which is consistent with previous studies. However, we claim that this correlation suffers from various artificial effects, e.g., FIR detection limits, survey volumes, and so on. We will discuss the limitations of studying the connection between AGN and star formation using currently available facilities.
