In response to diverse external stimuli, sensory receptors generate spiking nerve signals. These generated signals are transmitted to the brain along the neural pathway to advance to the stage of recognition or perception, and then they reach the area of discrimination or judgment for remembering, assessing, and processing incoming information. We review research trends in neuromorphic sensory perception technology inspired by biological sensory perception functions. Among the various senses, we consider sensory nerve decoding technology based on sensory nerve pathways focusing on touch and smell, neuromorphic synapse elements that mimic biological neurons and synapses, and neuromorphic processors. Neuromorphic sensory devices, neuromorphic synapses, and artificial sensory memory devices that integrate storage components are being actively studied. However, various problems remain to be solved, such as learning methods to implement cognitive functions beyond simple detection. Considering applications such as virtual reality, medical welfare, neuroscience, and cranial nerve interfaces, neuromorphic sensory recognition technology is expected to be actively developed based on new technologies, including combinatorial neurocognitive cell technology.

The purpose of this research was to understand how individuals reflect on the frequency and quantity of foods that they consume. Participants selected 5 males and 15 females aged 30 years or older were first interviewed on the frequency of their food consumption. Then based on this data, they were given a cognitive interview using the method of verbal proving. The individual cognitive interviews were recorded with consent while being conducted after complete approval by the Seoul National University Institution Review Board. The recorded material was evaluated using a thematic analysis after transcribing them into text. By analyzing stages of reflection, the major barriers to make the device difficult are revealed: 1) More difficulty in remembering events over the course of a full year due to diversification in the types of food that people consume 2) difficulty calculating the average for seasonal foods 3) difficulty estimating the amount of consumption from the photos presented 4) difficulty estimating amount of consumption from the quantity presented 5) difficulty processing foods that people think are healthy and foods are unhealthy simultaneously 6) difficulty having to consider foods where target food goes in as an ingredient; 7) difficulties arising from having to increase frequency when the amount consumed is higher than the quantity that is presented 8) difficulty having to combine the frequency and quantity of each food item when numerous foods are clustered into one category. These findings show that the less participants were involved in cooking, the more diverse their eating habits were, and the more they tried to adhere to rules of filling out the questionnaire, the more it was difficult for them to come up with an answer to the question being asked. It therefore seems necessary to construct a Food Frequency questionnaire that is attentive to these problems that arise from the recall stages.

The purposes of this study were to examine the consumer's behavior on the brands applying the characters by gender, age and residential district, and then to propose the future planning of brands applying the characters and distribution strategies. From Junior on middle school to forty-year olds were selected for this study and areas were grouped to five for comparing the residential distinction. The questionnaire was consisted with 25 questions. Nominal scale and 5-interval scale were used for analysis. The SPSS 12.0 was used to analyze the technical statistics such as average, frequency, t-test, ANOVA, and $x^2$. The results of this study were as follows : 1) The characters influenced on remembering the brand's name regardless gender, agen and residential district. 2) When consumer bought the brand with character, the most important factor is the brand name recognition. 3) It would be desirable to use the one or two mixed methods which express the characters on the clothes. 4) When they distribute the character brands, they would supply more feminine characters in 3rd district, more manly one in 4th district and less quantities in the 3rd and 4th district for lowering inventory. The next must be follow to succeed the character using strategy of fashion brands. It is needed to segment the target for new character creation of specific generation, and to grasp the point of the trend which oriented by the target, and to reflect what they like and what they feel sympathy on character image and brand concept.

The aim of this paper is to show how the paradigm of disaster resilience may help reorienting urban planning policies in order to mitigate various types of risks, thanks to carefully thought action on heritage and conservation practices. Resilience is defined as the "capacity of a social system to proactively adapt to and recover from disturbances that are perceived within the system to fall outside the range of normal and expected disturbances." It relies greatly on risk perception and the memory of catastrophes. States, regions, municipalities, have been giving territorial materiality to collective memory for centuries, but this trend has considerably increased in the second half of the 20th century. This is particularly true regarding the memory of disasters: for example, important traces of catastrophes such as urban ruins have been preserved, because they were supposed to maintain some awareness and hence foster urban resilience - Berlin's Gedachtniskirche is a well-known example of this policy. Yet, in spite of preserved traces of catastrophes and various warnings and heritage policies, there are countless examples of risk mismanagement and urban tragedies. Using resilience as a guiding concept might change the results of these failed risk mitigation policies and irrelevant disaster memory processes. Indeed, the concept of resilience deals with the complexity of temporal and spatial scales, and with partly emotional and qualitative processes, so that this approach fits the issues of urban memory management. Resilience might help underlining the complexity and the subtlety of remembrance messages, and lead to alternative paths better adapted to the diversity of risks, places and actors. However, when it is given territorial materiality, memory is almost always symbolically and politically framed and interpreted; Vale and Campanella had already outlined this political aspect of remembrance and resilience as a discourse. Resilience and the territorialization of memory are not ideologically neutral, but urban risk mitigation may come at that price.

Purpose: The purpose of this study was to identify over time the changes of cancer symptom, depression and quality of life (QOL) among people who had stomach or colorectal cancer. Methods: Of the 74 participants recruited, 67 participated in the study. Participants were asked to complete three instruments at three different time. The instruments were the M. D. Anderson Symptom Inventory-Gastrointestinal Cancer Module, Hospital Anxiety Depression Scale, and the Functional Assessment of Cancer Therapy-General. The questionnaires were administered before chemotherapy, toward the end of chemotherapy, and six months after the completion of adjuvant therapy. Data were analyzed using descriptive statistics and repeated measure ANOVA. Results: At the immediately after chemotherapy point, the most frequent symptom was lack of appetite, followed by fatigue and problem with remembering things. The mean score for depression was 8.27 with a prevalence of 31.3%. The mean score for quality of life was 61.88 out of 135. Repeated measures ANOVA showed a significant increase in cancer symptom (F=23.22, p<.001) and depression (F=35.29, p<.001) after chemotherapy. However, improvement was observed 6 months after the completion of chemotherapy. QOL (F=33.73, p<.001) also showed similar patterns as observed with cancer symptom and depression. Cancer symptom was the strongest predictor of QoL at pre-chemotherapy point. but depression was the strongest predictor at immediately after chemotherapy point. Conclusion: Chemotherapy is highly associated with cancer symptom, depression and QOL in patients with cancer. The nursing intervention is needed to relieve depression as well as cancer symptoms to improve QOL in patients undergoing chemotherapy from baseline to follow-up.
