We try to generate something new by interrogating ourselves on the notion of design science and on the notions derived during designing the design science. At the very beginning of designing, we introduce the notion of designing as an activity of constructing a new system. Then, first, we generate a hypothetical model of such a constructive process as repetitions of the cycles of synthesis (or, generation), analysis, and focusing towards a preferred situation. Second, we analyze the model with reference to processes of making artifacts. Third, on the basis of the analysis, we give ourselves the direction to the sophistication of the model and introduce the variables that should complement the model. We repeat the loop of the first, the second, and the third. As implied above, we design the model of the constructive process and apply the model to our activity of designing the model.

Tef (Eragrostis tef) is one of the world’s minor small-grained cereals. It is domesticated in northeastearn Africa and still cultivated as a food crop almost exclusively in Ethiopia and Eritrea. However, it is the major crop in these countries, because, despite its low yield per area, which is less than half that of maize, it is cultivated over a larger area than any other crop. Moreover, its cultivation in Ethiopia has increased in area substantially in recent decades. The significance of this cereal is difficult to understand from the perspective of modern agronomy, which privileges high yield, and raises the question why tef is important in this area. This article addresses this question by examining the case of the Malo people, among whom the author has conducted anthropological research. About 80,000 Malo farmers inhabit a steep mountainous area in southwestern Ethiopia that ranges in elevation between ca 1,000–3,000 meters above sea level (asl). Tef, which is currently sown as a dominant cereal in the lowlands between 1,000 and 2,000 meters asl, is cultivated using several unique techniques, which suggests that it was not introduced recently. However, according to local memory, the current landscape of its widespread cultivation is relatively new and has been estimated as less than 50 years. Several factors such as the introduction of cassava and other new crops in the lowlands have contributed to the recent increase in its cultivation. However, the largest contributor to the increase may be the adoption of the spongy sour pancake made from the cereal as its main material, which is an Ethiopian national dish commonly known as injera, as a local diet, following the Ethiopian Revolution in the mid-1970s, and its popularity among the people. Thus, the case of the Malo exemplifies a dynamics of development whereby food and agriculture are closely connected.

In the era of big data, personal information has been widely shared and used, which facilitates personal life, social production and public management but also brings the risk of personal information abuse.Personal information has multiple values involving with personality dignity and freedom, economic use, and public management. Meanwhile, the stakeholders relevant to personal information have become more and more diverse, leading to increasingly urgent demand for sharing and using personal information. With the great improvements in the processing efficiency and transmission rate of personal information, it has become much easier to share personal information, which makes the application of the principle of informed consent more difficult. In this circumstance, "Rational Expectation"rule becomes a new option of personal information protection in the era of big data. By assessing the risk of personal information sharing with matrix method in application contexts, it discusses the criteria of risk control under rational expectation rule. If the risk assessed is at the level of low risk, the sharing and use of personal information in this context complies with the rational expectation rule; If the risk assessed is at the level of medium risk, it is necessary to take measures timely and actively to reduce the risk and reassess the risk; If the risk assessed is at the level of high risk, the rational expectation rule is not applicable, the personal information controller should significantly inform the information subject and obtain consent before sharing the personal information. If there are multiple risk points in the application context, when and only when each risk level judged must be low risk, the rational expectation rule can be applied. Based on the rational expectation rule, we can achieve the balance of interests among personal information protection, digital economic development and public interest maintenance, so as to coordinate the promotion of digital innovation, economic development and social progress, and realize the unity of effective protection and rational use of personal information.

The reflections and diffractions of global navigation satellite system (GNSS) signals from buildings may produce large measurement errors. Detecting non-line-of-sight signals using 3D maps is a means to detect and exclude satellites with large measurement errors. However, the true position is typically needed for using 3D maps. In this study, we verify the assumption that an approximate user position can be used when using 3D maps. We found that the correct fixed position of real-time kinematic GNSS (RTK-GNSS) could be achieved when approximate positions for RTK-GNSS assisted by 3D maps were within 5-15m from the true position.

We propose and demonstrate the lateral integration of a VCSEL and a slow-light VCSEL amplifier with in-plane resonant wavelength detuning design, enabling the unidirectional coupling and stable single-mode operation with good beam quality. The modelling and simulation result of the wavelength detuning and unidirectional coupling is shown. A slow light laterally coupled from the VCSEL to the amplifier can be amplified uniformly when the amplifier is pumped above the threshold current. We also present the experimental data of the beam quality, output power and spectrum. The measured data show the increased single-mode output power with good beam quality in comparison with conventional VCSELs. A record single-mode power (40 mW) with narrow beam divergence (<0.06°) is presented.

Delays can have a negative impact on the stability of various systems. However, it was reported that the transmission delays of signals among oscillators can stabilize unstable equilibrium points in coupled oscillators, which is called amplitude death (AD). AD caused by delays has been extensively researched in the field of nonlinear science and has attracted attention for various engineering applications. In this article, we review the latest studies on AD caused by delays in oscillator networks, in particular those that considered heterogeneous delays and time-varying networks.

本稿では,「居場所」を提供しようとする支援への利用者の参加の経験を,参入-定着-退出の3段階に分節化し,就労・就学に代表される,外部社会への参加までの過程を連続的・動態的に明らかにすることを試みた。分析の結果,「居場所」支援の利用者たちは数々の社会的実践から「周縁化」されているが故に,「居場所」への参加にも困難を伴っており,支援者たちは利用者の責任の度合いを下げる形で利用者を「居場所」の「周辺」に位置づけようとしていること,こうした「居場所」利用者としてのアイデンティティの構築を経て,利用者は一般社会で広く通用する汎用的な資源を「居場所」に見出していること,外部社会への参加後は「居場所」利用者としてのアイデンティティは否定されること,などが明らかになった。こうした「居場所」への参加過程を「居場所」と外部社会の「二重の成員性」を獲得する過程として位置づけた。

本研究は,統合失調症患者の社会生活技能と自尊感情の因果関係を明らかにするために,地域で生活する患者61名の縦断データを用いて,社会生活技能と自尊感情の因果関係モデルを作成し,モデルのデータへの適合を検討した。結果,統合失調症患者の高い社会生活技能は自尊感情の高さを規定するが,高い自尊感情をもっていることが統合失調症患者の社会生活技能を良好にするわけではないということが示された。本研究の成果は,統合失調症患者がより良い自尊感情を得るには,社会生活技能を高めたり維持することが有効な方法の一つであるというエビデンス(evidence)を得たことであるが,今後,統合失調症患者の自尊感情が変容するプロセスについて質的な研究が必要である。

Aggravation of asthmatic response (asthmatic attack, 2 cases) and adverse events (tremor, 1 case) due to a switch from a brand-name tulobuterol tape to a generic tape were recently reported. These changes disappeared after reformulation from generic to the brand-name tape. To investigate this issue, we conducted a questionnaire survey on changes of asthmatic response, adverse events and product usability due to a switch between tulobuterol tapes. We identified 44 cases (18 from doctors, 26 from pharmacists) in which changes of asthmatic response or adverse events had occurred due to a switch between tulobuterol tapes. Aggravation of asthmatic response had occurred in 30 cases and adverse events in 21 cases due to switch from brand-name tulobuterol tape to generic tape. As regards change of product usability, we obtained 96 relevant responses (18 from doctors, 78 cases pharmacists), and the major response was that generic tulobuterol tape peeled off the skin more easily than did the brand-name tape (60 cases). These results suggest that changes of asthmatic response, adverse events and product usability should be carefully monitored when switching tulobuterol tapes.

本稿では,石川県金沢市の用水路の水音を対象に,地域住民が音をどのように聞き取り,特徴づけているのかを明らかにした。まず,対象とする音を定量的に把握するため,音圧レベル測定と音聞き調査を行った。その結果,環境省の定める騒音レベルを超える大きな音が堰から鳴っていることが明らかとなった。また,街路や建物など,街の形状によって音の聞こえる範囲が異なっていること,流量の変化により季節で音の範囲が変わることが示された。次に,住民の音環境の認識を明らかにするため,アンケート調査とグループインタビュー調査を行った。その結果,住民らは意識的に用水路の音は聞いていないが,無意識下で評価をくだしていた。これは,住民らにとって用水路の音が基調音となっていることを示唆している。また,音の評価は,住民の生活との関わりの中で行われていることが明らかとなった。
