기존의 가정용 건강측정기는 기기만이 독립적으로 사용되거나 기기로부터 생체정보를 전송 받아 로컬 컴퓨터에서만 처리하는 시스템이 주를 이루었다. 본 논문에서는 가정용 건강측정기 중 혈당측정기를 적외선 통신(Infrared Communication, IrDA)으로 PocketPC에 연결하여 혈당정보를 전송받는다. 이러한 정보를 PocketPC용 CDMA(Code Multiple Access) 확장 팩을 이용하여 문자메시지(Short Message Service, SMS)로 다른 휴대폰에 전송하고, 무선 랜(WLAN, IEEE 802.11)을 이용하여 웹서버에 있는 게시판에 건강측정정보를 자동 등록 하여 정보를 공유할 수 있는 시스템을 구축하였다. 특히 비공개된 혈당측정기의 프로토콜을 분석하여 통신에 사용하였으며, API(Application Programming Interface)를 제공하지 않는 CDMA 확장팩 시스템의 사용자용 프로그램을 IPC(Inter Process Communication)를 이용한 제어를 통해 필요한 태스크를 수행하는 기법을 사용하였다.

This study developed and evaluated a shoe cushioning system to reduce impact force patterns during running. The shoe cushioning system is composed with a poly urethane pocket, which contains water and porous grains to absorb the force against the weight inside the pocket. Load-displacement curves for the shoe cushioning system were obtained from an instrumented testing machine and the results were compared with various pockets that have air, water or grains. Mechanical testings showed that the pocket with 5 g particles was the best for the shoe cushioning system. This founding will be helpful to designing the shoe.

Full depth precast concrete bridge deck system can be advantageously to reduce construction time, hence lowering the cost. This system has several significant design and construction component. To connect between the concrete slab and steel girder, precast deck has shear pocket. Post-tensioning tightens the joints and prevents any leakage though the joint. When post-tensioning is applied, stress concentration occurs in the edge of shear pocket. In this study, precast decks using four types of shear pocket is analyzed by F.E.M.

In the zigzag milling of a pocket having islands, tool retraction is one of the primary factors that decrease productivity. Therefore, tool path with minimum number of tool retraction has been needed. Most researches about this topic have been concentrated on obtaining the optimum solution formulated through the geometric reasoning off pocket. Recently, several attempts were made to simplify this problem into region partitioning in order to get the numerically expressed minimum solution. In this research, a method reducing the number of tool retractions extended from existing region partitioning is provided. Applying the segment that is normal to the reference direction of zigzag milling, region partitioning is carried out and structural elements of the region are searched via graphs of islands and characteristic points. Through the processes presented, the number of region partitioned is less than that of existing processes.

PDA(Personal Digital Assistant)와 같은 Mobile 이동통신기기를 사용한 인터넷 쇼핑은 향후 E-Commerce 시장에서 가장 크게 확산되어질 한 분야로 부상되고 있다. 그러나 현재 인터넷상에 혼재 되어있는 수많은 정보에 대하여 Pocket PC 환경상의 제한된 Screen Size와 느린 통신 속도, 무선 인터넷 접속시의 높은 비용, 저장능력의 한계 등의 문제로 웹 브라우징을 통한 다량의 웹 데이터에 대한 확인과 검색이 어렵고, 사용자가 원하지 않는 정보 또한 산재되어 있어 개인화된 검색 서비스의 요구가 대두되고 있다. 본 연구에서는 PDA 및 Pocket PC를 이용하는 사용자의 관심도를 기준으로 보다 편리하고 효율적인 개인화 Interface의 제공 및 이를 이용한 손쉬운 웹 브라우징 방식을 제시한다. 또한 User 인터랙션 정보를 통해 피드백 함으로써 보다 완벽하게 사용자 개인별 취향에 접근할 수 있는 브라우징 기법을 제시한다.

인터넷 기술의 발전과 사용범위 및 영역이 지속적으로 확장되고 있지만 아직도 네트워크 연결성을 제공할 수 없는 원격지역과 상황들이 상당히 존재한다. Pocket Switched Network(PSN)은 모바일 송수신 장치를 휴대한 사람이 제공하는 이동성을 활용하여 인터넷을 사용할 수 없는 지역에서도 데이터 전송을 가능케 하는 네트워크로서 PSN에서는 노드의 이동성, 링크 고장, 배터리 방전 등의 문제점을 고려하여 데이터 전송을 위한 네트워크 연결성을 계속적으로 유지해 주는 것이 매우 중요하다. 본 논문에서는 현재까지 제안된 주요 PSN 라우팅 기법들을 살펴보고 이것들의 성능을 분석하기 위해 네트워크 노드 수를 증가시키면서 전송 확률, 오버헤드 비율, 평균 전송지연, 평균 잔여에너지양의 변화를 실험을 통해 비교한다. 또한, 실험 결과를 통해 데이터 전송을 최대화하면서 에너지 소비는 최소화하여 네트워크 수명을 연장할 수 있는 기법을 제시한다.

Objectives : The purpose of this study was to determine the impact of the sociodemographic and health characteristics on the out-of-pocket health spending of the individuals aged 20 and older in Korea. Methods : We used the data from the 2001 National Public Health and Nutrition Survey. The final sample size was 26,154 persons. Multiple linear regression models were used according to the age groups, that is, one model was used for those people under the age of sixty-five and the other was used for those people aged sixty-five and older. In these analyses, the expenditures were transformed to a logarithmic scale to reduce the skewness of the results. Results : Out-of-pocket health expenditures for those people under the age of 65 averaged 14,800 won per month, whereas expenditures for those people aged 65 and older averaged 27,200 won per month. In the regression analysis, the insurance type, resident area, self-reported health status, acute or chronic condition and bed-disability days were the statistically significant determinants for both age groups. Gender and age were statistically significant determinants only for the non-elderly. Conclusions : The findings from this study show that the mean out-of-pocket health expenditures varied according to the age groups and also several diverse characteristics. Thus, policymakers should consider the out-of-pocket health expenditure differential between the elderly and non-elderly persons. Improvement of the insurance coverage for the economically vulnerable subgroups that were identified in this study should be carefully considered. In addition, it is necessary to assess the impact of out-of-pocket spending on the peoples' health care utilization.

Background: The out-of-pocket maximum is one of the distinctive healthcare systems which sets a ceiling on co-payment in order to reduce the burden of households from the unpredictable medical expenditure. However, this leads to an increase in the demand for healthcare services especially in long-term care hospitals (LTCHs) in Korea. Methods: This study analyzed the influence factor of medical service overuse of 165,592 inpatients in LTCHs which out-of-pocket maximum is applied, by utilizing data from the National Health Insurance Service (2016). Based on Anderson Model, the medical service overuse, as a dependent variable, was defined as long-stay admission more than 180 days at the LTCHs. Independent variable was comprised of predisposing factors (gender, age), enabling factors (income level, types of out-of-pocket maximum) and need factors (illness level, patient use of tertiary hospital). Results: The most powerful factor of medical service overuse in LTCHs was availability of pre-payment for the out-of-maximum (odds ratio [OR], 191.66; p<0.001). This tendency was found in high income level status (p<0.001). Furthermore, mild inpatients (OR, 1.50; p<0.001) which had no experience with the tertiary hospitals (OR, 2.06; p<0.001) were more relevant to the medical service overuse in LTCHs, compared to the severe inpatients. Conclusion: It is suggested that a separate standard of out-of pocket maximum with regards to LTCHs is required to secure the beneficial functions of long-term hospitals and prevent unnecessary financial leakage to achieve sustainable and financially sound National Health Insurance.
