Data Result

The Indonesian government is putting an effort into reducing the number of gasoline-fueled vehicles and replacing them with electric energy-based vehicles. This is stated in the General Draft of the National Energy Plan (RUEN), which is aimed at increasing the resilience of the national energy sector. Motorcycles are the largest contributor to the vehicle population in Indonesia at 82%. As the Indonesian government intends to stimulate the replacement of gasoline-fueled motorcycles by electric motorcycles, it is useful to conduct a study on the preferences related to motorcycle product designs among two-wheeled vehicle users in Indonesia. This study used the Kansei Engineering method to get a design direction as well as a factorial analysis for data result processing in order to obtain a unique design factor. The number of respondents in this study was 104 people from Jakarta and Bandung. The results of this study show that the respondents wanted an overall design that looks playful and masculine yet compact and active. In addition, the design has to have elements of a big scooter. This study was designed as an initial stage within the R & D process of electric motorcycle products and will be further developed in a follow-up study.

Long Term Follow Up

The authors report the case of a man with cervical ossification of the posterior longitudinal ligament (OPLL) who was observed for more than 26 years. Initial symptoms consisted of subtle numbness of the hands, and initial radiography showed small, segmental-type OPLL in the cervical spine. Lateral radiography of the cervical spine was performed every few years. Ossification accelerated for about 4 years during the follow-up. Segmental-type OPLL developed into mixed-type extensive OPLL. This case shows an accelerating maturation process of OPLL over the course of a few years. Segmental-type OPLL appears to represent an initial stage of extensive OPLL.

Objective Metrics

Quantification of subjective attributes expressed as functions of design variables is a significant challenge in creating product design optimization models. For example, the objective assessment of a vehicle’s environmental friendliness is typically based on fuel economy and emissions. But some design variables such as a vehicle’s silhouette (two-dimensional body shape) may create a subjective perception of environmental friendliness, which may impact consumer preference along with objective metrics. In this paper, we show a method for assessing subjective attributes in the context of design attributes. We focus on perceived environmental friendliness (PEF) and we develop a model of PEF as a function of vehicle silhouette shape variables. The modeling process consists of stimuli development using design of experiments, survey design including direct assessment of the key subjective attribute PEF, elicitation of consumer preference, measurement of purported subjective mechanisms (for the PEF case, whether the design is “inspired by nature”), measurement of respondent characteristics (for the PEF case, environmental attitudes and demographics), statistical analysis of data, and validation. Results for the PEF example indicate that silhouettes perceived as environmentally friendly are the most preferred. Design variables that correlated with PEF were identified and used to generate new designs, which were validated in a follow-up study. Implications of using the general methodology in engineering design are discussed.

Blastic plasmacytoid dendritic cell tumor is a rare, highly aggressive systemic neoplasm for which effective therapies have not yet been established. We describe a 73-year-old man with multiple nodules and patches emerging on the trunk and limbs. Lesional skin biopsy revealed a plasmacytoid dendritic cell tumor with dense dermal infiltrate of tumor cells with blastoid features. No apparent systemic involvement was identified in the initial stage. The patient was treated with prednisone daily, with notorious improvement of the skin lesions, although no complete remission was obtained. During the six-month follow-up period, no disease progression was documented, but fatal systemic progression occurred after that period of time.

Kansei Engineering is a technical methodology to translate consumer’s Kansei into product design elements. The target of this technology is to provide designers and manufacturers with a technique to master the emotional and spiritual needs of consumers and then manifest them in product design to enhance competitive edge. In light of this situation and on the basis of finishing a lot of English literature reading about this technology, the author conducted systematical study about Kansei Engineering in this thesis with the aim to enhance understanding of it for domestic designers and accelerate spread of it. Basing on the study about the situations of China’s domestic design industry, the author analyzed several points that China’s design industry should learn from Japan and Kansei Engineering technology, and proposed a simplified Kansei Engineering Model which is easier to execute and suitable for domestic design industry. In conclusion, this paper gives an introduction to the theory of Kansei Engineering system, and explores the relationship between consumer's desire and massage chair design factor with the SD (Semantic Differential) method, providing effective reference for the massage chair design.

Staged Reconstruction

The usual operative procedures (primary tracheal anastomosis, cricotracheal anastomosis, skin grafting and stenting, pedicle cartilage grafts, or free rib grafts) used to correct stenoses of great length involving the trachea or laryngotrachea have a high incidence of failure. An alternative method of reconstruction is the open technique, which requires three stages. The initial stage creates a trough after resection of the stenotic area, followed by subcutaneous embedding of a rigid material adjacent to the trough, and finally closure of the trough by reformation of the anterior wall. This staged procedure has been used in adult patients with tracheal stenoses greater than 4 cm, in patients with tracheal stenoses involving the cricoid, and in patients whose primary corrective operative procedures have failed. This paper critically assesses 30 patients who have had a staged reconstruction with a minimum follow-up of 12 months. The indications, number of procedures performed, time required for decannulation, complications, and analysis of failures are presented. The incidence of success in this series of patients is 76% (23/30).

Overhead transmission lines are important carriers of electric energy transmission. Their icing, galloping and shedding in winter and spring seriously threatened the safe operation of Shanxi power grid. Especially in the recent years, compact lines and double circuit lines on the same tower, typical types of overhead transmission lines in Shanxi Power Grid, were affected by frequent trips induced by icing, galloping, and shedding appeared in their conductors repeatedly, which seriously reduced the capacity of power energy transmission in Shanxi and caused trillions of power load losses. Through detailed investigation and analysis of the characteristics and historical fault cases of compact lines and double circuit lines on the same tower in Shanxi Power Grid, the key causes and main laws of two types of lines in Shanxi Power Grid are clarified, which could provide support for the follow-up line anti-ice technical transformation and capacity improvement.

Importance: Persistent symptoms are reported in patients who survive the initial stage of COVID-19, often referred to as ″long COVID″ or ″post-acute sequelae of SARS-CoV-2 infection″ (PASC); however, evidence on incidence is still lacking, and symptoms relevant to pain are yet to be assessed. Objective: To determine long-term symptoms in COVID-19 survivors after infection. Data Sources: A literature search was performed using the electronic databases PubMed, EMBASE, Scopus, and CHINAL and preprint servers MedRχiv and BioRχiv through January 15, 2021. Study Selection: Eligible studies were those reporting patients with a confirmed diagnosis of SARS-CoV-2 and who showed any symptoms persisting beyond the acute phase. Data Extraction and Synthesis: Incidence rate of symptoms were pooled using inverse variance methods with a DerSimonian-Laird random-effects model. Main Outcomes and Measures: The primary outcome was pain-related symptoms such as headache or myalgia. Secondary outcomes were symptoms relevant to pain (depression or muscle weakness) and symptoms frequently reported (anosmia and dyspnea). Heterogeneity among studies and publication bias for each symptom were estimated. The source of heterogeneity was explored using meta-regression, with follow-up period, age and sex as covariates. Results: In total, 35 studies including 18,711 patients were eligible. Eight pain-related symptoms and 26 other symptoms were identified. The highest pooled incidence among pain-related symptoms was chest pain (17%, 95% CI, 12%-25%), followed by headache (16%, 95% CI, 9%-27%), arthralgia (13%, 95% CI, 7%-24%), neuralgia (12%, 95% CI, 3%-38%) and abdominal pain (11%, 95% CI, 7%-16%). The highest pooled incidence among other symptoms was fatigue (45%, 95% CI, 32%-59%), followed by insomnia (26%, 95% CI, 9%-57%), dyspnea (25%, 95% CI, 15%-38%), weakness (25%, 95% CI, 8%-56%) and anosmia (19%, 95% CI, 13%-27%). Substantial heterogeneity was identified (I2, 50-100%). Meta-regression analyses partially accounted for the source of heterogeneity, and yet, 53% of the symptoms remained unexplained. Conclusions and Relevance: The current meta-analysis may provide a complete picture of incidence in PASC. It remains unclear, however, whether post-COVID symptoms progress or regress over time or to what extent PASC are associated with age or sex.
