일반적으로 두부는 만드는 방법이나 두부의 성질에 따라 다양한 형태의 두부가 있다. 두부의 효능으로는 혈중 지질, 지단백, 콜레스테롤 등의 농도를 감소시켜 동맥경화와 뇌혈관을 깨끗하게 하여 심뇌혈관계 질환을 예방하는 효과가 있다. 또한 장내 유용균의 증식을 촉진하는 역할을 하며 콜레스테롤 배설을 촉진시키고, 장 기능에 대한 생리적 효과와 식사 후 혈당 상승 억제와 인슐린 분비를 억제하는 효과가 있다. 그리고 두부에는 칼슘이 풍부해 뼈 손상을 막아주고, 뼈 조직의 생성에 도움을 주는 효과를 가지고 있어 골다공증 예방 및 치료에 효과가 있다. 반면, 빈혈이 있는 사람의 경우 두부 섭취 시 주의해야 한다. 콩에 들어있는 phytic acid라는 물질은 아연 및 철분과 같은 무기물의 흡수를 저해하기 때문에 철 결핍성 빈혈 환자는 더 심한 철분 부족이라는 결과를 초래할 수 있으므로 섭취 시 주의해야 한다. 따라서 건강식품으로 선호되고 있는 두부의 부족한 부분을 보완하기 위해 다양한 천연 첨가제를 활용한 추가적인 연구가 필요할 것으로 생각된다.

Purpose: Resorption of the alveolar bone is an unavoidable consequence of tooth extraction when appropriate alveolar ridge preservation (ARP) measures are not taken. The objective of this trial was to test the hypothesis that dimensional changes in the alveolar bone after tooth extraction would be reduced by inserting an equine collagen membrane and a collagen cone to fill and seal the alveolus (as ARP), in comparison to extraction with untreated alveoli. Methods: In this randomized clinical trial, 31 patients were directly treated with the collagen material after extraction of a tooth from the maxilla (the ARP group). Twenty-nine patients served as the control group. After extraction, no further treatment (i.e., no socket preservation measures) was performed in the control group. Changes in the alveolar process immediately after extraction and after an 8 (${\pm}1$)-week healing period were evaluated 3-dimensionally. Blinded analyses were performed after superimposing the data from the digitalized impressions and surfaces generated by cone-beam computed tomography. Results: Both the ARP and control groups showed a reduction of bone in the alveolar area after tooth extraction. However, significantly less bone resorption was detected in the clinically relevant buccal region in the ARP group. The median bone reduction was 1.18 mm in the ARP group and 5.06 mm in the control group (P=0.03). Conclusions: The proposed hypothesis that inserting a combination material comprising a collagen cone and membrane would lead to a difference in alveolar bone preservation can be accepted for the clinically relevant buccal distance. In this area, implantation of the collagen material led to significantly less alveolar bone resorption. German Clinical Trials Register at www.drks.de, DRKS00004769.

Objectives : Medical qigong, originated from Mawangdui Daoyintu (馬王堆 導引圖), mainly consists of meditation, physical movements, and breathing exercises. It has been widely used to cure a variety of diseases as a regimen in Oriental medicine. This study was aimed to analyze the characteristics of medical qigong movements in the Mawangdui Daoyintu and to observe a link between each medical qigong movement and meridian system. Methods : We extracted fourteen medical qigong movements from forty-four figures in Mawangdui Daoyintu. We compared the 14 medical qigong movements of the Mawangdui Daoyintu with other types' movements of medical qigong methods. We also analyzed each movement of medical qigong in Mawangdui Daoyintu with a perspective of meridian system. Results : We found that there were common features between the medical qigong movements of the Mawangdui Daoyintu and other types' movements of medical qigong methods, including Yukjagyeol (六字訣), Paldangum (八段錦), Yukgengyeng (易筋經) and so on. From the comparison of each movement and meridian qi flow, we also found several movements related with Liver meridian and one movement related with several meridians. Conclusions : Our findings would be beneficial to understand the movements of medical qigong in the Mawangdui Daoyintu from the perspective of meridian system. This would be useful to develop a new medical qigong movements applying the meridian qi system for health and healing.

As patients prefer large scale hospitals recently, the interior design of general hospitals are conspicuously improving. In the past, most patients visit hospitals to get treatment on diseases; however, recently patients visiting hospitals for the early prevention of disease is rapidly increasing. Accordingly, contemporary hospitals should meet the wish of patients who want to get medical service in more clean and comfortable environment. The existing studies on hospital interior design were mostly limited on analyzing the functionality of each space; however, studies on the interior design of common use space, which is open to all hospital users, are required now. Accordingly, this study classified the common use space in contemporary general hospitals into lobby space, corridor space, waiting space and resting space. The interior design characteristics of each space were classified into; connectivity with external environment, level change by void, introduction of natural elements, dynamics of space and variety of color. Then a case analysis was done by selecting 12 common use spaces in overseas general hospitals. According to the analysis result, the interior design characteristics were more conspicuous in the sequence of corridor space, lobby space, resting space and waiting space. The interior design elements such as overall space arrangement and material-finishing were relatively acceptable; however, the aspect of a user's environmental behavior, in other words, the psychological aspect, which can lead a patient to natural healing, was relatively insufficient. It is believed that an in-depth interior design focusing on practical users would enable various spatial behaviors. It is hoped that this study would be a help to the interior design of domestic general hospitals as a guideline.

Mastic is a bleed resin formed in pistacia lentiscus tree extract form the anacatdiaceae family. Mastic is used as a food ingredient in the Mediteraanean resin, and has been used by local inhabitants as a traditional medicine for relief of upper abdominal discomfort, dyspepsiaand peptic ulcer. Clinically, mastic has been effective in the treatment of benign gastric and duodenal, ulcers, giving symptomatic relief and endoscopically proven healing. In this study, to enhance activiteies of poorly water soluble Mastic with oils, surfactants and cosurfactants and then the mixure was microemulsified in aqueous media under condition of gentle agitation and digestive motility that would be encountered in the gastrointestinal tract. Formulation development and screening were based on phase diagrams and characteristics of resultant microemulsion. For optimum mastic formulation, microemulsions with various ratio (w/w%) of mastics, oils, surfactants and cosurfactants were prepared and their solubility was evaluated by monitoring particles size in their buffer through visual asessment and electrophoretic light scattering spectrophotomerter (ELS). In vitro activity of self microemulsified mastic (SME mastic) was determined by minimum ingibition concentration (MIC) test against a panel of Helicobacter pylori (H. pylori) clinical strains. Additionally, in vivo activity of SME masitc was investigated us mouse infected by CH275 of H. pylori. The mean diameter of SME mastic was less then 100 nm in water and SME mastic was showed similar antiboisis effect compared to tometronidazole, clarithromycin and omeproazole. Consequently, SME mastic would be effective system to exterminate H. pylori. If mastic were dose with combined treatment, mastic might augur well for effect of H. pylori eradication as good remedy.

The ripe fruit of Hass avocado contains one of the highest elvels of cytochrome P-450 protein found in the plant kingdom. To determine whether wounded roots of avocado contain P-450 protein, the roots of avocado were wounded by slicing, and then allowed to incubate in sealed plastic bags, in 0.4M mannitol, and in the solution to make protoplast preparation containing cellulysin and macerase during the specified times. The microsomal proteins were extracted from the samples, separated by SDS-PAGE, and then subjected to Western blot analysis using polyclonal antibodies which are generated against the CYP71A1 protein. wounded roots in sealed bags produced CYP71A1 within 6 hours after cutting, and those in 0.4M mannitol did not produce CYP71A1 even after 72 hours, but those in the protoplast preparation by cellulysin and macerase induced and produced CYP71A was induced in only 24 hours. These results indicate that CYP 71A1 plays a role for wound healing for root tissue o avocado, and would-inducible P-450 protein was not detected in the mannitol solution by preventing a synthesis of ethylene in a liquid state, but the softening of tissues by cellulysin and macerase to make protoplast preparation was involved in an activation of CYP 71A1 even in the liquid state.

Reconstruction of calvarial bone defects from congenital anomaly or from bone loss due to traumatic or neoplastic processes remains a significant problem in craniofacial surgery and neurosurgery. To facilitate bone regeneration, there have been many trials such as autologous bone graft or allograft, and the addition of demineralized bone matrix and matrix-derived growth factor. Guided bone regeneration is one of the methods to accelerate bone healing for calvarial bone defects especially in children. Pericranium is one of the most usable structure in bone regeneration. It protects the dura and sinus, and provides mechanical connection between bone fragments. It supplies blood to bone cortex and osteoprogenitor cells and enhances bone regeneration. For maximal effect of pericranium in bone regeneration, authors used pericranium as a flap for covering calvarial defects in surgeries of 11 craniosynostosis patients and achieved satisfactory results: The bone regeneration of original cranial defect in one year after operation was 74.6%(${\pm}8.5%$). This pericranial flap would be made more effectively by individual dissection after subgaleal dissection rather than subperiosteal dissection. In this article, we reviewed the role of pericranium and reported its usefulness as a flap in surgery of craniosynostosis to maximize bone regeneration.

Networking together hundreds or thousands of cheap sensor nodes allows users to accurately monitor a remote environment by intelligently combining the data from the individual nodes. As sensor nodes are typically battery operated, it is important to efficiently use the limited energy of the nodes to extend the lifetime of the wireless sensor network (WSN). One of the fundamental issues in WSNs is the coverage problem. In this paper, the border coverage problem in WSNs is rigorously analyzed. Most existing results related to the coverage problem in wireless sensor networks focused on planar networks; however, three dimensional (3D) modeling of the sensor network would reflect more accurately real-life situations. Unlike previous works in this area, we provide distributed algorithms that allow the selection and activation of an optimal border cover for both 2D and 3D regions of interest. We also provide self-healing algorithms as an optimization to our border coverage algorithms which allow the sensor network to adaptively reconfigure and repair itself in order to improve its own performance. Border coverage is crucial for optimizing sensor placement for intrusion detection and a number of other practical applications.
