정보화 사회로 대두되는 현대사회는 컴퓨터 확산 및 네트워크의 급속한 발전과 더불어 이를 이용한 많은 응용분야들이 연구되고 있으며, 이중 전자투표에 관한 연구 또한 활발히 진행중이다. 이는 기존의 투표 방식을 전자화할 경우 시간 및 비용 측면에서 많은 절약효과를 얻을 수 있기 때문이다. 그러나 이런 효율성에도 불구하고 전자투표를 실제 적용하는데 있어서 투표 참여 요소의 부정 및 투표권 매매와 투표자 익명성 보장 등 아직 해결해야 할 많은 문제점들이 산재해 있다. 따라서 본 논문에서는 기존 투표를 전자투표로 적용시키는 과정에서 필요한 일반적 요구사항과 부정방지 및 매매방지를 위한 특수 요구사항을 살펴볼 것이다. 특히, 투표자 익명성 보장 및 매매방지를 위해 네트워크 상에서 투표내용이 공개되더라도 사용자 익명성을 보장할 수 있는 Magic Sticker 기법을 적용함과 동시에 사용자 인증 및 메시지 인증 부분에서는 자신을 밝히지 않은 상태에서 수신자를 지정하여 자신의 신분을 증명할 수 있는 수신자 지정 그룹 서명 방식을 이용함으로서 사용자 익명성을 제공하는 안전한 전자 투표 방식을 제안한다.

In order to elucidate the effect of spreader-stickers on the rainfastness of dithianon and chlorothalonil wettable powders, and to estimate the possibility of suggesting good new formulations, the fungicide residues on the leaf surface of hot pepper was assessed and compared after the drop-wise applications of fungicide suspensions containing spreader-sticker on leaf surface followed by artificial raining. Three commercial spreader-stickers, which were Cover, Reitron and Silwet, not only made the rainfastness of dithianon wettable powders worse on hot pepper leaf, but increasing their concentrations also accelerated it further. On the other hand, to chlorothalonil wettable powder, Reitron showed the 3-fold improvement of rainfastness. But, for the rest, there was no improvement as well. The effect of N-octylpyrrolidone (NOP) on rainfastness of both fungicides was excellent. Soybean oil formulations containing leaf-penetrable nonionic surfactant, which was either polyoxyethylene monotridecyl ether or polyoxyethylene monolauryl ether, improved dithianon rainfastness, but the ones containing conventional emulsifiers did not.

This study is conducted to develop a new method of early occurrence monitoring for Aculops lycopersici Massee (Acari: Eriophyidae), a major pest in tomato. A. lycopersici causes damage to plants such as curling of leaflet edges, followed by leaflet bronzing. As feeding continues by the mites, the plant takes on a russeted, wilted appearance, eventually culminating in leaflet desiccation and finally plant death. Fruit damages in tomato were shown when the density of mites was very high. Also, A. lycopersici caused more damage to unripe fruits than ripe fruits. The time taken to detect A. lycopersici on green label sticker was 7.0 seconds, the shortest. Blue, orange and white label stickers took 17.1, 19.8 and 12.3 seconds respectively. The permeable microscope with side illumination was useful in observing A. lycopersici on label stickers. A. lycopersici began to occur in late-April and the density of the mites increased rapidly after mid-May. The density peaked in mid to late-June, and decreased after late-June. A. lycopersici was observed on lower stems 20 days after the release of mites and observed on higher stems 60 days after. The peaked densities were observed on stems 40 and 60 days after and on leaf 80 days after. The label sticker is enough to monitor early occurrence of A. lycopersici in tomato cultivation facilities.

Purpose: This study was to analyze the characteristics and effect size of intervention studies that used acupressure for the control of chemotherapy-induced nausea and vomiting (CINV). Methods: Nine electronic databases including Korea Education Research and Information, the National Assembly Library, KISS, Korea Med, NDSL, PubMed, EBSCO, Cochrane library, and OVID (to December, 2009) were searched. Thirteen studies of randomized controlled trials (RCTs) or controlled clinical trials (CCTs) were selected. Data were analyzed by SPSS/WIN 18.0. Results: Overall effect size of acupressure was moderate (0.684). Nausea had a moderate effect size (0.770) and nausea and vomiting had a high effect size (0.899). Acupressure using sticker needles had a high effect size (1.368) among finger acupressure, si-acupuncture, and wrist band treatment. Conclusion: This study suggests that acupressure using sticker needles on the spots of nei-guan, chok-samni and hap-kok can reduce the levels of nausea and vomiting in cancer patients receiving chemotherapy. For improving the reliability of the meta-analysis results, further randomized controlled trials with better study methodology are needed.

The lenticular Location Based System is related to a location information technology. The system enables users to inform their location in real time wherever in a room, a building, a ship, a basement. In this paper, we analyze limitations and problems of the existing indoor Positioning System and propose a method of user-oriented location service. The proposed method consists of a lenticular sticker, a database(DB) acquisition and analysis technology. The proposed system can be used as an infrastructure to implement various indoor location-based services. In addition to improve user centered positioning accuracy through the development of location-based systems using indoor lenticular systems, it can be used in a disaster situation.

Purpose: This study aimed to develop new digital navicular drop test (ND-NDT) equipment and to determine its validity and reliability. Methods: A total of 24 healthy male and female adults, who fully understood the purpose of the study and gave consent to participate in the study, were selected as participants. The NDT and ND-NDT were conducted in the dominant foot of the participants in a random order. For the NDT, the position of the navicular bone was marked with a pen first; then, the height of the navicular bone from the ground was measured in both sitting and standing positions. For the ND-NDT, after the sticker-type reflection markers were attached to the position of the navicular bone, the height of the navicular bone from the ground was measured in both sitting and standing positions. To assess the validity of the diagnostic tests, the same examiner measured the height of the medial longitudinal arch (MLA) three times in both the sitting and standing positions. To assess the inter-rater reliability of the ND-NDT, three examiners, in a random order, attached the sticker-type reflection markers to the position of the navicular bone and then measured the height of the MLA in both positions. Results: In the sitting position, the Pearson correlation coefficient (r) between the two diagnostic tests was very high (r = 0.97) and statistically significant. In the standing position, the Pearson correlation coefficient (r) between the two tests was 0.95, which was also statistically significant. The ICC_2,1 values in the sitting and standing positions were 0.93 and 0.95, respectively, indicating significantly high inter-rater reliability. Conclusion: The ND-NDT equipment showed very high diagnostic validity, as well as excellent inter-rater reliability, indicating the clinical usefulness of the equipment as a diagnostic system for confirming pes planus.

Hospital pharmacy services are divided into dispensing affairs for inpatients and outpatients, pharmaceutical service, stock control, intravenous admixture service, drug information service, pharmacokinetic consultation service, education and research work, etc. But among those affairs, dispensing affair for outpatient is perceived as the most important work in Korea, because it is linked directly with hospital service for patients. Therefore, total computer system for dispensing area was adopted from opening point of hospital in 1989 in Asan Medical Center. Utilization of computer system for outpatient dispensing area is as follows; 1) Order communication system of prescription by Total Hospital Information System, 2) Automatic print-out system of direction for use by sticker connected with on-line net work, 3) Use of automatic tablet counting and packaging machines connected with on-line net work. Those computer system resulted in curtailment of pharmacy manpower and shortening of waiting-time for outpatient.

RFID(Radio Frequency IDentification) is a method of remotely storing and retrieving data using devices called 'RFID tags'. An RFID tag is a small object, such as an adhesive sticker, that can be attached to or incorporated into a product. RFID tags contain antennas to enable them to receive and respond to radio-frequency queries fro an RFID transceiver. Eventually, RFID SYSTEM is very interesting to watch people live linger than they used to before. Some of reasons for that phenomenon is the improving medical studies. As we live healthier and get to know more about our body, we can extend our lives. This Platform is Physical Health Promotion Service, Home Health Monitoring Service, Mental Health Promotion Service, Home Patient Management Service, Chronic Disease Management Service, Emergency Patient Management Service, Medical Information and Consulting Service of the RFID.

We theoretically consider blends of two monodisperse one-end-functionalized homopolymers (denoted by A and B) capable of forming clusters between functional groups (stickers) using weak segregation theory. In this model system resulting molecular architectures via clustering resemble star copolymers having many A- and B-arms. Minimizing the total free energy with respect the cluster distribution, the equilibrium distribution of clusters is obtained and used for RPA (Random Phase Approximation) equations as input. For the case that polymers are functionalized by only one kind of sticker, the phase diagrams show that the associations promote the macrophase separation. When there is strong affinity between stickers belonging to the different polymer species, on the other hand, the phase diagram show a suppression of the macrophase separation at the range of high temperature regime, as well as the phase coexistence between a disordered and a mesoscopic phase at the relatively lower temperatures.
