As a main challenge in network virtualization, virtual network embedding problem is increasingly important and heuristic algorithms are of great interest. Aiming at the problems of poor correlation in node embedding and link embedding, long distance between adjacent virtual nodes and imbalance resource consumption of network components during embedding, we herein propose a two-stage virtual network embedding algorithm NA-PVNM. In node embedding stage, resource requirement and breadth first search algorithm are introduced to sort virtual nodes, and a node fitness function is developed to find the best substrate node. In link embedding stage, a path fitness function is developed to find the best path in which available bandwidth, CPU and path length are considered. Simulation results showed that the proposed algorithm could shorten link embedding distance, increase the acceptance ratio and revenue to cost ratio compared to previously reported algorithms. We also analyzed the impact of position constraint and substrate network attribute on algorithm performance, as well as the utilization of the substrate network resources during embedding via simulation. The results showed that, under the constraint of substrate resource distribution and virtual network requests, the critical factor of improving success ratio is to reduce resource consumption during embedding.

Background : This study focuses on the new acupuncture method of embedding method which inserts a substance on the acupuncture points for continuous stimulation. Clinical applications and cautions were examined through literary investigations. Results : Based on the literary consideration of embedding method, the following results were obtained : 1. Embedding method is a combination of traditional and embedding technique to provide longer duration of stimulation on the acupuncture points. 2. To administer the embedding method, one needs to utilize a embedding thread besides acupuncture apparatus. Sheep gut is commonly used in China and the surgical thread is the choice in Korea. 3. Embedding method may vary from the patient to patient, depending on the nature and location of the illness. Piercing, embedding, and tying are some of the possibilities. 4. Embedding method may have different arrangement of threads based on the choice of usage. 5. Embedding method is effective for various chronic illnesses such as aches, functional diseases, and the diseases of internal organs. 6. When using the embedding methods, cautions against infection and side effects due to strong stimulation are mandatory.

Objectives : The purpose of this study is to help select an appropriate word embedding method when analyzing East Asian traditional medicine texts as data. Methods : Based on prescription data that imply traditional methods in traditional East Asian medicine, we have examined 4 count-based word embedding and 2 prediction-based word embedding methods. In order to intuitively compare these word embedding methods, we proposed a "prescription generating game" and compared its results with those from the application of the 6 methods. Results : When the adjacent vectors are extracted, the count-based word embedding method derives the main herbs that are frequently used in conjunction with each other. On the other hand, in the prediction-based word embedding method, the synonyms of the herbs were derived. Conclusions : Counting based word embedding methods seems to be more effective than prediction-based word embedding methods in analyzing the use of domesticated herbs. Among count-based word embedding methods, the TF-vector method tends to exaggerate the frequency effect, and hence the TF-IDF vector or co-word vector may be a more reasonable choice. Also, the t-score vector may be recommended in search for unusual information that could not be found in frequency. On the other hand, prediction-based embedding seems to be effective when deriving the bases of similar meanings in context.

Thread embedding therapy is used increasingly for various disease including neck pain. However, the evidence of thread embedding therapy on neck pain and the assessment of their methodology are still limited. This study aimed to investigate the clinical research methodology using thread embedding therapy on neck pain. Thread embedding therapy is used increasingly for various disease including neck pain. However, the evidence of thread embedding therapy on neck pain and the assessment of their methodology are still limited. This study aimed to investigate the clinical research methodology using thread embedding therapy on neck pain. Total 31 studies were included in analysis. Thread embedding therapy usually was used once a week(32.3%), once per 10days(29.0%), once per two weeks (25.8%). The most common concurrent treatment used with thread embedding therapy was Chinese medicine. Among acupuncture points, EX-B2 (61.3%) was most commonly used, followed by GV14(45.2%), GB20(29.0%), GB21(22.6%). For control group, acupuncture were most commonly used(58.1%). All studies reported that the effect of thread embedding therapy was more effective compared to control group. and 11 studies reported side effects. Only 13 studies(41.9%) reported the appropriate randomization method, and the mean Jadad score of included studies was 1.52. Previous clinical trials included in this study showed the effect of thread embedding therapy for neck pain. However, the quality of the studies was not high. Further rigorous clinical trials are need to assess the effect of thread embedding therapy.

Objectives : The purpose of this study was to investigate the clinical effects of Korean medical treatments combined with Embedding acupuncture on patients with chronic lower back pain. Methods : We reviewed the medical records of 40 patients with chronic lowerback pain hospitalized at Dongshin Korean Medicine Hospital from March, 2015 to February, 2016. They were divided into two groups: the embedding acupuncture group(20 patients) and the non-embedding acupuncture group(20 patients). To evaluate the efficacy of the treatments, the 40 patients were asked to complete a Numerical Rating scale (NRS) and the Oswestry Disability Index (ODI) four times during admission. Results : The mean NRS of the embedding acupuncture group decreased more significantly than the non-embedding acupuncture group at days three and ten of admission. The ODI change and ODI rate of change of the embedding acupuncture group were significantly greater than the non-embedding acupuncture at days three and ten of admission. Conclusion : Korean medical treatment combined with embedding acupuncture might be effective in reducing pain and improving the life quality of patients with chronic lower back pain. We hope that further studies will be done to produce more clinical data and ensure effective application of these results.

Objectives : The aim of this study was to observe the effect of Embedding therapy on complete facial palsy after primary treatment. Methods : 11 patients with complete facial palsy were treated with Embedding therapy. It was performed once a day, every two weeks. 15~20 Embedding threads were used in each Embedding therapy treatment. The total number of Embedding therapy treatments was 4 or 8. Frontalis muscles (including the Yangbaek ($GB_{14}$)), Orbicularis oculi muscle, Levator labii superioris muscle, Zygomatic major muscle, Zygomatic minor muscle (including the Georyo ($ST_3$) and Jichang ($ST_4$)), Masseter muscle, Buccinator muscle (including the Hyeopgeo ($ST_6$)) and Orbicularis Oris muscle were selected. Yanagihara's score and House-Brackmann scale were compared for before and after treatment to evaluate the effect of Embedding therapy. Results : Yanagihara's score increased significantly (p=0.003). House-Brackmann Scale decreased significantly (p=0.005). Three patients were extremely satisfied, six patients were satisfied, and two patients responded neutrally in regards to Embedding therapy. Conclusions : Embedding therapy can be effective in improving symptoms of complete facial palsy.

To increase the applicability and productivity of hydroforming process, hydro-embedding process was developed by combining the hydro-forming process with embedding process simultaneously. It is necessary in the automotive parts to form hollow bodies with connection elements which combine one part with another. The hydro-embedding process is embedding the connection element hydraulically during the operating steps of the hydroforming. In this study, technique of rotational piercing is added on the existing hydro-embedding to increase the connection force of hydro-embedded element. To estimate the feasibility of new trial process, integrated researches on the hydro-embedding process technology have been performed by analyzing the deformed mode of the tubes and the optimal process parameters for various shapes of the connection elements.

Steganographic schemes which are based on minimizing an additive distortion function defined the overall impacts after embedding as the sum of embedding costs for individual image element. However, mutual impacts during embedding are often ignored. In this paper, an adaptive JPEG steganographic method based on weight distribution for embedding costs is proposed. The method takes mutual impacts during embedding in consideration. Firstly, an analysis is made about the factors that affect embedding fluctuations among JPEG coefficients. Then the Distortion Update Strategy (DUS) of updating the distortion costs is proposed, enabling to dynamically update the embedding costs group by group. At last, a kind of adaptive JPEG steganographic algorithm is designed combining with the update strategy and well-known additive distortion function. The experimental result illustrates that the proposed algorithm gains a superior performance in the fight against the current state-of-the-art steganalyzers with high-dimensional features.

Objectives : The purpose of this study is to review the thread embedding treatment studies of obesity in Traditional Chinese Medicine. Methods : We reviewed 59 studies on cat-gut-embedding treatment of obesity which were published from 2005 to 2012. The studies were searched using the data base-CAJ(China Academic Journals; 中國期刊全文數據庫)(2005~2012). Results : Selected 59 studies were divided into 27 case series and 32 control studies. The number of studies has increased since 2005, more rapidly in 2011~2012. Most case series reported were about effectiveness of thread embedding monotherapy treating obesity. Control studies reported were about effectiveness of thread embedding treatment compared with acupuncture, electroacupuncture, and medicine. Most studies on thread embedding treatment of obesity showed that its effectiveness was very good. Conclusions : There have been many reports of thread embedding treatment studies of obesity in Traditional Chinese Medicine. We believed that these studies could be applied to the clinical practice and basic research in Korea.
