In this study, the optimum criteria of space between the lines and the letters which could largely affect the legibility were found by the experiment and were presented as guidelines to design Korean VDT screens. Since the experiment was designed to test the human performance based on the VDT screen design, searching speed (S.S) and error rate (E) were used as the criteria of performance, and CFF value was measured to evaluate user's visual fatigue. The EOG value was also measured for the visual restriction during the experiment for the space between the lines and letters.

Using the photoimageable thick film conductors, $25\mu\textrm{m}$ line widths and $25\mu\textrm{m}$ spaces can be obtained. Test patterns are made by green tape lamination, paste printing, exposing to UV light, developing in an aqueous process and cofiring. Postfiring method using alumina substrate can be also applied to fine line formation. Series gap resonator formed by photopatterning process showed the improved signal transmission characteristics compared to that obtained by conventional screen printing.

고분자 전해질 연료전지의 성능과 내구성에 미치는 막 전극 접합체(MEA) 제조방법의 영향에 대해 연구하기 위해 닥터 블레이드 방법, 스프레이 방법, 스크린 프린트 방법 그리고 스크린 프린트+스프레이 방법에 의해 MEA를 제조하였다. 제조된 MEA를 체결한 단위전지의 성능을 측정해 각 MEA의 초기 성능을 비교하였다. 10초간 0.6V 일정전압 유지 후 0.9 V에서 10초간 유지하는 전극 열화 가속 시험(AST)을 각 MEA 적용해 내구성을 시험하였다. 전극 열화 가속 시험 6,000 사이클 전 후 I-V 곡선, 임피던스, 순환 전압측정법(CV), 선형쓸음 전기량측정법(LSV), 투과전자현미경(TEM) 등을 측정하였다. 닥터 블레이드 방법에 의해 제조한 MEA의 초기 성능이 제일 높았고, 스크린 프린트+스프레이 방법에 의해 제조한 MEA가 제일 낮은 열화 속도를 보였다.

This paper is a study on what kind of effect non-verbal communication in mobil electronic commerce has on purchase intention and visual attention. For this purpose, the screen of mobile shopping mall produced arbitrarily was exposed to the experimental group and the control group. The experimental group was exposed to the screen of mobile shopping mall that expressed non-verbal communication making use of cinemagraph images and the control group was exposed to the screen of mobile shopping mall based on still images. For the study, survey research and experimental research were conducted simultaneously. Data of survey research were analyzed by MANOVA and t-test, and by using eye-tracker experimental research recorded the duration of time that the subjects stared images. The results of experiment show that in non-verbal communication the experimental group that saw cinemagraph images recorded shorter average staring time than the control group that saw ordinary images, and the cinemagraph had statistically significant effect on visual attention as well. And it was analyzed that non-verbal communication had significant effect on the purchase intention of the experimental group, but had no effect on the purchase intention of the control group. The results can be interpreted that the people who saw cinemagraphs in mobile shopping environment had spent shorter time in seeing products than the people who saw ordinary images, but still the former came to have purchase intention on the products. The results of the present study can be useful for marketers who try to sell agrifood in mobile environment.

본 연구는 신체적 특성과 기능적 움직임 검사(FMS)의 융합적 상관관계에 대해 알아보고자 한다. 연구대상자는 정상 성인으로 193명을 대상으로 단일측정하였다. 자료분석은 SPSS 26.0 Ver 프로그램으로 T-검증을 실시하였고, 각 변수들 간 피어슨 상관계수로 분석을 하였다. 분석결과, 검사 방법 중 능동 뻗은 다리 올림 검사와 몸통 안정성 푸쉬업 검사 영역에서 성별 간에 유의한 차이가 나타났다(P<.05). 어깨 가동성 검사와 능동 뻗은 다리 올림 검사 영역을 제외한 나머지 FMS의 검사에서 체지방률과 부적 상관관계가 있었다. 능동 뻗은 다리 올림에서 여성이 기능적 움직임의 질이 높았으며, 몸통 안정성 푸쉬업에서는 남성이 기능적 움직임의 질이 높았다. 그러므로 남성은 하지의 유연성을 보강해야하며, 여성은 상체 근력과 몸통의 안정성 운동을 적용해야 한다고 판단된다.

Colorectal cancer (CRC) is now common in Thailand with an increase in incidence over time. Health authorities are planning to implement a nationwide CRC screening program using fecal immunochemical test (FIT) as a primary screening tool. This study aimed to estimate preferences and acceptance of FIT and colonoscopy, explore factors influencing the acceptance, and investigate reasons behind choosing and rejecting to screen before the program was implemented. Patients aged 50-69, visiting the primary care unit during the study period, were invited to join this study. Patients with a history of cancer or past CRC screening were excluded. Face-to-face interviews were conducted. Subjects were informed about CRC and the screening tests: FIT and colonoscopy. Then, they were asked for their opinions regarding the screening. The total number of subjects was 437 (86.7% response rate). Fifty-eight percent were females. The median age was 58 years. FIT was accepted by 74.1% of subjects compared to 55.6% for colonoscopy. The acceptance of colonoscopy was associated with perceived susceptibility to CRC and family history of cancer. No symptoms, unwilling to screen, healthy, too busy and anxious about diagnosis were reasons for refusing to screen. FIT was preferred for its simplicity and non-invasiveness compared with colonoscopy. Those rejecting FIT expressed a strong preference for colonoscopy. Subjects chose colonoscopy because of its accuracy; it was refused for the process and complications. If the screening program is implemented for the entire target population in Thailand, we estimate that 106,546 will have a positive FIT, between 8,618 and 12,749 identified with advanced adenoma and between 2,645 and 3,912 identified with CRC in the first round of the program.

본 연구에서는 다양한 색채환경에 대한 반응을 파악하기 위해 3차원 가상환경 인터페이스를 개발하고, 개발된 인터페이스에 대해 사용자가 어떻게 감성적으로 인터렉션하는지를 평가하였다. 3차원 가상환경은 후면 투사형 대형화면을 통해 제시되었으며, 가구를 포함한 실내 환경요소에 12가지 색채조합을 적용한 후, 피실험자들에게 색채조합에 대한 반응과 아울러 가상환경 인터페이스를 통한 감성적 인터렉션을 함께 평가하도록 하였다. 총 34명의 대학생들이 실험에 참여하였으며, 피실험자들은 대형화면 ($8'{\times}6'$)에 제시되는 고화질의 색채 환경 속에서 표준 입력장치를 사용하여 360도로 시선을 움직일 수 있었다. '공간적 실재감(Spatial Presence)', '주제와 연관성(Topic Involvement)', 및 '유쾌함(Enjoyment)'에 관한 자기보고형 설문지를 통해 가상환경파의 인터랙션을 통한 감성 및 인지적 반응을 파악하였다. 현 연구는 향후 디자인 연구, 특히 환경디자인 연구에 3차원 가상환경 인터페이스를 적용하고자 하는 연구자들이 사용자 인터랙션을 사전에 이해하는데 기여할 것으로 기대된다.

육상수조를 이용한 해산어의 양식은 사육환경의 악화와 질병발생 등으로 인하여 생산성이 점차 저하되고 있으며, 배출수로 인해 양식장 주변연안의 환경문제점을 유발하고 있다. 따라서, 본 연구는 시스템 및 자동화 설계기술을 이용하여 유입수처리를 위한 스크린필터와 배출수 처리를 위한 드럼필터의 개발을 위한 기초단계로서 각각에 대한 개념 설계를 수행하고, 이를 바탕으로 한 실험용 모델의 제작가 운행을 수행하였다. 그 결과 현장용필터제작에 필요한 초기설계 및 상세설계에 대한 자료를 얻을 수 있었으며, PLC를 이용한 자동화는 장치의 효용성을 향상시킬 수 있었다.

Seoul Metro and Seoul Metropolitan Rapid Transit Corp. have started installing screen doors at subway platforms to improve the environment of subways and prevent passengers' accidents since 2006. They are still installing screen doors at subway platforms and Metropolitan Rapid Transit Corporations in other areas are also proceeding with installment of screen doors or making preparations for it. Grounding is necessary for installing PSD systems. In case that PSD grounding is connected with existing electrical equipment grounding system, it was decided to install separate grounding for safe operation of PSD system and passenger safety. However, it's very difficult to install new grounding at the subway station compound. A way to improve this condition is that we proceed with grounding by composing grounding station by carbon grounding rod. This paper will mainly deal with how to design and construct carbon ground rod, which has been applied to PSD system grounding since 2006, including its experimental examples. In this paper, ways to secure ground resistance below 5 ohms, which is resistance necessary for PSD grounding, and to compose grounding system were also discussed. Furthermore, a ground test to check the ability to fulfill a role of PSD grounding system was conducted. As a result of applying carbon grounding module, PSD system is being operated without any problem and the installment of PSD system will be continuously expanded in the future. It's also thought that a way to integrate grounding of each functional room which has been installed at the subway station compound and to arrange equipotential grounding should be reviewed and performed promptly.
