Purpose: The aim of this study was to examine the characteristics of hypertension-related nursing intervention programs and their effects on systolic and diastolic blood pressure. Methods: Fifteen studies were selected from four databases (Korean studies, Riss4U, RICHIS, and JKAN) published as of 2009. They were analyzed by meta-analysis method. The selected studies contained a control group with pre-test and post-test design, measured blood pressure as a dependent variable, and used a reported statistical value for blood pressure to measure the size of effects. Results: The hypertension-related nursing intervention programs were relatively effective in lowering both systolic and diastolic blood pressure, although they were more efficient to decrease diastolic pressure. Among the hypertension-related intervention programs, complementary and alternative therapies were more effective in lowering blood pressure compared to lifestyle change intervention. Conclusions: To acquire substantial data of intervention effects, and complementary and alternative therapy, subjects in pre-hypertensive stage, and elderly people, better industrial and scholastic research methods need to be developed for future research. Further studies are needed to establish complementary and alternative therapies. Studies with different group of participants and studies using effective research design are in need as well.

본 연구는 보완대체요법을 활용한 긍정심리프로그램 중재를 통하여 간호대학생의 정신적, 사회 심리적 건강향상을 위하여 시도되었다. 보완대체요법을 활용한 긍정심리프로그램을 제공받은 간호대학생을 실험군으로 프로그램을제공받지 않은 간호대학생을 대조군으로 선정하여 간호대학생의 부정적 정서(우울, 불안, 스트레스), 진로결정 자기효능감, 자기자비, 플로리시에 미치는 효과를 검증하기 위한 비 동등성 대조군 전후 유사실험 설계를 적용한 연구이다. 수집된 자료는 SPSS Version 21.0 프로그램을 이용하여 분석하였다. 실험군은 교육에 참여하지 않은 대조군보다 진로결정 자기효능감, 자기자비, 플로리시 점수가 높았고, 부정적 정서 점수가 낮은 것으로 나타났다. 보완대체요법을 활용한 긍정심리프로그램을 적용한 후 진로결정 긍정적인 연구 효과를 보고함으로 보완대체요법을 활용한 간호중재영역 확대에 기여하였다.

In the design of a complementary electrochromic windows based on $WO_3/Li^+$ conducting electrolyte/$V_2O_5$ system, a characterization of electrochromic properties of $WO_3/V_2O_5$ complementary devices as a function of thickness combinations is necessary in order to predict such as the safe operating voltage, the optical modulation range and the optical switching response. In this paper, the effects of $WO_3\;and\;V_2O_5$ thin films thickness combinations on device performance were systematically investigated.

Broadband metal-dielectric-metal terahertz filters composed of complementary rings are designed and demonstrated. Four samples with different parameters were fabricated. Results measured using THz time-domain spectroscopy system show excellent agreement with simulations. Compared with the broadband filters reported before, the complementary ring structure in our design is insensitive to any polarization at normal incidence due to symmetry of the ring. Furthermore, the influence of structure parameters (such as period, radius, slot width, thickness and incidence angles) on the transmission characteristics has been investigated theoretically. The encouraging results afforded by designing of the filters could find applications in broadband sensors, terahertz communication systems, and other emerging terahertz technologies.

Cupping therapy (CT) is used in Asia, Europe, and the Middle East and is prevalent in Muslim communities where it is recommended by the Prophet of Islam. The majority of modern, medical practitioners interested in CT, view it as a medical technique and distance themselves from the mechanisms proposed by traditional medicine. However, modern medicine does not offer a valid explanation for the mechanisms involved in CT. There is growing evidence of CT's effectiveness, specifically in chronic pain management when compared to an inactive control, but not against sham treatment. CT accompanied by religion and prayer, as it is in Muslim communities, cannot be considered to be equivalent to any procedures in modern medicine. "Whole System Research" may be the most appropriate trial design to test the ancient practice of CT efficacy whilst pending development of a novel placebo for assessing the connectivity of body and mind interventions.

Purpose: The purpose of this study was to identify influencing factors of using numbers and period of complementary and alternative therapy (CAT) among chronic patients. Methods: The study employed a descriptive design. The participants were 221 chronic patients. Data were collected in a pharmacy near a general hospital from April to July, 2008. Results: Influencing factors on using number of CAT were age, numbers of disease, period of used CAT and monthly expenses on CAT (the ability to explain, 79.9%). Influencing factors on using period of CAT were the period of illness and using number of CAT (the ability to explain, 44.9%). Conclusion: The results of this study suggest that chronic patients need counseling and guides about using CAT especially for those are older and have many kinds and longer period of diseases.

The purpose of this study is on comparing complementary forest of village between Korea and China. For this, Jinan of Korea and Qingzhou of China were selected through the pre-survey about the representative region of both country. The main research method was literature study, field study and interview with local residents. The comparative analysis between two regions was performed by frequency analysis of surveyed data. Which shows complementary forest of village in two regions has so much in common and also has many differences which is related with the local practical life. As a result, it was identified that the area and remained number, concentration degree of Jinan were greater than those of Cheongju. But it was identified that the linear form and location were similar in both regions. Through these identification, it is helpful to establish policy direction of both countries about the complementary forest.

3 나노미터 아래의 미래공정에서는 작은 면적의 표준셀(Standard Cell)을 구현하는 데에 많은 기술적인 개선을 요구한다. 따라서 어떠한 기술을 통해 얼마나 작은 면적의 표준셀을 구현할 수 있는지, 그리고 그 영향이 어떠한지 알아보는 것은 매우 중요하다. 본 논문에서는 3 나노미터와 이하의 미래공정에서 표준셀 설계를 위해 묻힌 전력망(Buried Power Rail, BPR)과 상호보완 FET(Complementary FET, CFET)이 면적 감소에 얼마나 기여하는지 살펴보며 그 영향을 기생 캐패시턴스 관점에서 분석한다. 본 논문을 통해 상호보완 FET은 4T 이하의 표준셀을 구현할 수 있는 기술이지만, Z-축으로 증가하는 높이만큼 상당한(+18.0% 이상) 기생 Cap의 영향을 받는다는 점을 밝힌다.

Energy harvesting technology, which scavenges electric power from ambient, otherwise wasted, energy sources, has been explored to develop self-powered wireless sensors and possibly eliminate the battery replacement cost for wireless sensors. Among ambient energy sources, vibration energy can be converted into electric power through a piezoelectric energy harvester. For the last decade, although tremendous advances have been made in design methodology to maximize harvestable electric power under a given vibration condition, the research in reliability assessment to ensure durability has been stagnant due to the complicated nature of the multiple failure modes of a piezoelectric energy harvester, such as the interfacial delamination, fatigue failure, and dynamic fracture. Therefore, this study presents the first-ever system reliability analysis for multiple failure modes of a piezoelectric energy harvester using the Generalized Complementary Intersection Method (GCIM), while accounts for the energy conversion performance. The GCIM enables to decompose the probabilities of high-order joint failure events into probabilities of complementary intersection events. The electromechanically-coupled analytical model is implemented based on the Kirchhoff plate theory to analyze its output performances of a piezoelectric energy harvester. Since a durable as well as efficient design of a piezoelectric energy harvester is significantly important in sustainably utilizing self-powered electronics, we believe that technical development on system reliability analysis will have an immediate and major impact on piezoelectric energy harvesting technology.
