In an effort to minimize operational expenses and supply users with more scalable services, distributed applications are actually going towards the Cloud. These applications, sent out over multiple environments and machines, are composed by inter-connecting independently developed services and components. The implementation of such programs on the Cloud is difficult and generally carried out either by hand or perhaps by composing personalized scripts. This is extremely error prone plus it has been found that misconfiguration may be the root of huge mistakes. We introduce AutoBot, a flexible platform for modeling, installing and (re)configuring complex distributed cloud-based applications which evolve dynamically in time. AutoBot includes three modules: A simple and new model describing the configuration properties and interdependencies of components; a dynamic protocol for the deployment and configuration ensuring appropriate resolution of these interdependencies; a runtime system that guarantee the proper configuration of the program on many virtual machines and, if necessary, the reconfiguration of the deployed system. This reduces the manual application deployment process that is monotonous and prone to errors. Some validation experiments were conducted on AutoBot in order to ensure that the proposed system works as expected. We also discuss the opportunity of reusing the platform in the transition of applications from Cloud to Fog computing.

Composing music is an inspired yet challenging task, in that the process involves many considerations such as assigning pitches, determining rhythm, and arranging accompaniment. Algorithmic composition aims to develop algorithms for music composition. Recently, algorithmic composition using artificial intelligence technologies received considerable attention. In particular, computational intelligence is widely used and achieves promising results in the creation of music. This paper attempts to provide a survey on the music generation based on the Monte Carlo (MC) algorithm. First, transform the MIDI music format files to digital data. Among these data, use the logistic fitting method to fit the time series, obtain the time distribution regular pattern. Except for time series, the converted data also includes duration, pitch, and velocity. Second, using MC simulation to deal with them summed up their distribution law respectively. The two main control parameters are the value of discrete sampling and standard deviation. Processing the above parameters and converting the data to MIDI file, then compared with the output generated by LSTM neural network, evaluate the music comprehensively.

Objectives : This study reviews whether the traditional medical thought process reflected in the Traditional Chinese Medical Treatment Plan for COVID-19 is based on existing classical texts, and examine concerns over the quality of evidence that the plan is based on. Methods : First, terminology and basic formulas composing the compound formulas in the COVID-19 TCM Treatment Plan were collected. Next, their usage in existing classical texts were searched in the medical classics database. Results : Infectious diseases similar to COVID-19 were understood as external disease due to Six Qi in the texts. Basic formulas used for treatment were those applied in Shanghan and Wenbing, among which cases where such formulas were applied in infectious diseases could be found in the classics. Conclusions : The level of evidence of the Treatment Plan suggested by various specialists could be evaluated as insufficient if we consider the literature. However, if application of such a plan could be supported institutionally, it could become a starting point for evidence generation.

Objectives : The purpose and application method of the five kinds of Gagamjeong-gisan in the Onbyeongjobyeon were analyzed and their significance was examined. Methods : First, contents within medical texts on the Gwakhyangjeong-gisan, the original formula for the Gagamjeong-gisan were analyzed. Next, application, symptoms and pathogenic mechanism, treatment principle, composition of the Gagamjeong-gisan as written in the Onbyeongjobyeon were analyzed. Characteristics of each formula as deduced from this process were compared and examined. Results : The Gwakhyangjeong-gisan covers both external contraction and internal damage, applied regardless of external or internal symptoms. It restores the Yang qi of the Spleen and Stomach, balancing the Zheng qi to respond to the external qi. The Gagamjeong-gisan takes after the Gwakhyangjeong-gisan, reflecting such properties. However, the latter differs in that it excludes ingredients unfit for treating dampness-warmth, and uses different application methods according to the level of discharge of dampness pathogen. Conclusions : The Gagamjeong-gisan is modified from the Gwakhyangjeong-gisan, which is applied to cold damage and internal damage to better treat warm disease. It can be said to have acted as a bridge for warm disease scholars in composing formulas that deal with dampness-heat disease.

The main purpose of this study is to arrange the diseases, principal medicinal substances and the prescriptions for the Soumin's Sinsooyul-Pyoyul-Byung(少陽人 腎受熱表熱病) by historical examination in the viewpoint of the Constitutional Medicine(四象醫學). In this study, first I collected the original texts of the diseases and priscriptions in Dongyi-Soose-Bowon(東醫壽世保元), and described the development process of the Soumin(少陽人)'s diseases and priscriptions by comparing with the contents in Dongyi-Soose-Bowon(東醫壽世保元). Next, I collected the efficacy of the medicinal substances and priscriptions by the examination of successive literatures referred it, and tried to explain the efficacy of each medicinal substances in the viewpoint of the Constitutional Medicine(四象醫學) by the analysis of successive literatures. As a result, the conclusions could be summarized as follows. 1. The Differentiation of Syndromes(辦證) in the Existing Medicine(旣存醫學) was formed according to the Eight Principal Syndromes(八綱), the Five Elements(五行), the Merdian system(經絡), therefore there were many confusions with the changes of the times. The differentiation of Syndromes(辦證) in the Constitutional Medicine(四象醫學) was formed according to the pathological change of Ascending and Descending Yin Yang(陰陽升降) in the Four Internal Organs(四臟), therefore, there was the consistency in the recognition of diseases. 2. The classification of the Soumin's Pyoyul-Byung(少陽人 表熱病) was divided into Yukuang Disease(鬱狂證) and Mangyang Disease(亡陽證) according to sweating or not. The conception of these diseases was mostly achived in Shanhanlun(優寒論). The treatment of Shanhanlun(優寒論) was alike to that of Dongyi-Soose-Bowon(東醫壽世保元) in a part. 3. Je ma, Lee thinked that the cause of the Soumin's Pyoyul-Byung(少陽人 表熱病) is the breakdown of the balanced equilibrium in ascending and descending Yin Yang(陰陽升降) for a Large Sin and a Small Bi(腎大脾小), and it is treated by warming and ascending Yang(溫補升陽). 4. The medicinal substances composing prescriptions for the Soumin's Pyoyul-Byung(少陰人 表熱病) is characterized with the efficacy of Ascending Yang and supplying Qi(升陽益氣) and regulating the digestive organs with the efficacy of warming it. 5. The medicinal substances composing the precriptions for the Soumin's Pyoyul-Byung(少陰人 表熱病) is divided into four parts with the state of Yang Qi(陽氣) in the disease it used. 6. The purpose of prescriptions for the Soumin's Pyoyul-Byung(少陰人 表熱病) is to strengthen the Soumin(少陰人)'s Yangnan Qi(陽暖之氣). Je ma, Lee kept the principle not to mix with another constitution's medicinal substances in the creation of the priscription.

The evaluation of organic matters and nutrients removal was investigated for the synthetic wastewater and the high strength of dairy wastewater. Two different systems were performed for this research. System A composing of a single RBC with tapered aeration was fed with the synthetic wastewater for 74 days with 173L/day of influent, 200% of internal return and 100% of sludge return for the period 1 and 2. The feed conditions were maintained 346L/day of influent, 50% of internal return and sludge return for the period 3. The dairy wastewater was introduced to evaluate treatment efficiency for system B composing of dual RBCs and tapered aeration tanks for 50 days of experimental run time, in which hydraulic rates were maintained at the constant ratios of 346L/day, 50% of internal return and 50% of sludge return. The spiral string media made of nylon fibre was attached by Bacillus sp. in RBC for both systems. The specific area of string media was $1.4m^2$/m and biomass was maintained at the concentrations of 23g/m. The synthetic wastewater was supplied by 1,800mg/L of glucose, 500mg/L of $NH_4Cl$, and 500mg/L of $KH_2PO_4$ to system A. The dairy wastewater was supplied to system B from dairy production plant. The average influent concentrations were 1,334mg/L of BOD, 2,014mg/L of CODcr, 160mg/L of T-N, and 12mg/L of T-P in system A. The average influent concentrations of parameters were 1,006 mg/L for BOD, 1,875mg/L for $COD_{cr}$, 51.6mg/L for T-N and 8.9mg/L for T-P in system B. Results indicated that removal efficiencies of BOD and $COD_{cr}$ were more than 90% however, the removal efficiency of T-N was 87%, and that of T-P was 82% for system A. Removal efficiencies were 98.5% of BOD, 91.3% of nitrogen and 89% of phosphorus for system B. The removal efficiencies of organic matters, T-N and T-P were higher in system B than in system A. The effluent quality issued by the stringent national legislations for the discharge of the high strength of dairy products wastewater can be improved using sequential RBCsand tapered aeration reactors rather than a single RBC and tapered aeration reactors with Bacillus sp.

Cu-cored Sn-Ag solder balls were fabricated by coating pure Sn and Ag on Cu balls. The melting behavior and the solderability of the BGA joint with the Ni/Au coated Cu pad were investigated and were compared with those of the commercial Sn-Ag and Sn-Ag-Cu balls. DSC analyses clarified the melting of Cu-cored solders to start at a rather low temperature, the eutectic temperature of Sn-Ag-Cu. It was ascribed to the diffusion of Cu and Ag into Sn plating during the heating process. After reflow soldering the microstructures of the solder and of the interfacial layer between the solder and the Cu pad were analyzed with SEM and EPMA. By EDX analysis, formation of a eutectic microstructure composing of $\beta$-Sn, Ag$_3$Sn, ad Cu$_{6}$Sn$_{5}$ phases was confirmed in the solder, and the η'-(Au, Co, Cu, Ni)$_{6}$Sn$_{5}$ reaction layer was found to form at the interface between the solder and the Cu pad. By conducting shear tests, it was found that the BGA joint using Cu-cored solder ball could prevent the degradation of joint strength during aging at 423K because of the slower growth me of η'-(Au, Co, Cu, Ni)$_{6}$Sn$_{5}$ reaction layer formed at the solder, pad interface. Furthermore, Cu-cored multi-component Sn-Ag-Bi balls were fabricated by sequentially coating the binary Sn-Ag and Sn-Bi solders on Cu balls. The reflow property of these solder balls was investigated. Melting of these solder balls was clarified to start at the almost same temperature as that of Sn-2Ag-0.75Cu-3Bi solder. A microstructure composing of (Sn), Ag$_3$Sn, Bi and Cu$_{6}$Sn$_{5}$ phases was found to form in the solder ball, and a reaction layer containing primarily η'-(Au, Co, Cu, Ni)$_{6}$Sn$_{5}$ was found at the interface with Ni/Au coated Cu pad after reflow soldering. By conducting shear test, it was found that the BGA joints using this Cu-core solder balls hardly degraded their joint shear strength during aging at 423K due to the slower growth rate of the η'-(Au, Cu, Ni)$_{6}$Sn$_{5}$ reaction layer at the solder/pad interface.he solder/pad interface.

The purpose of this study is to investigate prospective teachers' perceptions of the peer review comments readily available to them during the writing process in a teacher training class. Given these needs, we employ a qualitative method of inquiry giving voice to the learner's own view of peer feedback. The data we wish to consider is first-person narratives elicited from four EFL college students, who are prospective teachers of English. With regard to the EFL students' narrative considered here, all were attentive to the feedback they received. Moreover, the way in which these EFL writers talk about peer response activity reflects that they still welcome peer feedback because of the benefits to be accrued from it. Although this study, covering only four EFL students in total, can hardly be considered conclusive, we attempt to offer a synthesis of their stories. First of all, students indicate that they received responses from "authentic readers" (Mittan 1989, 209). We do note, consequently, that students gain a clear understanding of readers' needs by receiving feedback on what they did well and on what seems unclear. Perhaps the greater effect of peer feedback claimed by these students is that they take active roles in utilizing peer comments. Since they feel uncertain about the validity of their classmates' responses, students feel that they have autonomy over their own text and can make their own decisions on whether they should accept their peer comments or not. This contrasts with their treatment of teacher comments that they accept begrudgingly even if they disagree with them. Four EFL writers talked a lot, typically in a positive way, about peer response to their writing, yet they have expressed reservations about the extent to which they should put any credence in comments offered by their fellow students. Perhaps this is because their fellow students are still developing writers and EFL learners. In turn, they were sometimes reluctant to accept the peers' comments. Thus, in EFL contexts, L1 use can be suggested during peer feedback sessions. In particular, we have come to feel that L1 use enables both reviewers and receivers to have more productive peer review experiences. Additionally, we need to train students not "to see peer feedback as potentially bad advice" (Silva et al. 2003, 111). Teachers should focus on training students to utilize their peers' comments. Without such training, students will either ignore feedback or fail to use it constructively.
