One of the factors influencing children`s physical development and growth is the hygienic and healthy nutritional intake of food. To assure the balanced nutrition and good hygiene, many parents pack home-prepared meals in lunch boxes for their children to eat during school`s lunch break. However, not all children always share their parent`s concern. Some children may find that eating their home-prepared lunch at school is less interesting compared to eating snacks bought at school or playing with their friends during breaks. Thus, their parents sometimes have to be disappointed to see the lunch box return home still not empty. This study focuses on the effort of improving children`s eating behavior by designing a persuasive lunch box. We aim to persuade children to eat more, or even finish their home-prepared meals through a lunch box design which provides a novel, enjoyable, engaging and motivating experience in eating and finishing their meals. Currently, the design of existing lunch boxes used by children nowadays is quite attractive and appealing, yet lacks of persuasiveness. Participatory design was used as an approach in this study. A number of dedicated participants from the primary user group (5 to 9 years old children) and the secondary user group (caregivers) were highly involved throughout the design process.

A number of dedicated participants from the primary user group (5 to 9 years old children) and the secondary user group (caregivers) were highly involved throughout the design process. A list of user requirements was gathered from the interviews and observations concerning the current issues around the activity of eating and relevant children’s behavior. Three design concepts were developed based on the requirements and the pre-concepts generated during the conduct of a participatory design workshop with 12 participants (6 children and 6 parents). Low-fidelity prototypes (i.e. carton-based prototype, 3D model prototype and video prototype) were built based on the selected concept. The prototype evaluation showed that the user requirements have been successfully met. Moreover, some participants found the lunch box attractive, interactive and may provide a persuasive way towards changing children’s eating behavior.

Modulation of Biotransformation Enzymes by Phytochemicals : Impact of Genotypes

Johanna W. Lampe 한국식품영양과학회 2004 한국식품영양과학회 학술대회발표집 Vol.55 No.-

Modulation of biotransformation enzymes is one mechanism by which a diet high in fruits and vegetables may influence cancer risk. Inhibition of cytochrome P450s (CYP) and concomitant induction of conjugating enzymes are hypothesized to reduce the impact of carcinogens in humans. Thus, exposure to types and amounts of phytochemicals may influence disease risk. Like other xenobiotics, many classes of phytochemicals are rapidly conjugated with glutathione, glucuronide, and sulfate moieties and excreted in urine and bile. In humans, circulating phytochemical levels vary widely among individuals even in response to controlled dietary interventions. Polymorphisms in biotransformation enzymes, such as the glutathione S-transferases (GST), UDP-glucuronosyltransferases (UGT), and sulfotransferases (SULT), may contribute to the variability in phytochemical clearance and efficacy; polymorphic enzymes with lower enzyme activity prolong the half-lives of phytochemicals in vivo. Isothiocyanates (ITC) in cruciferous vegetables are catalyzed by the four major human GSTs; however reaction velocities of the enzymes differ greatly. In some observational studies of cancer, polymorphisms in the GSTM1 and GSTT1 genes that result in complete lack of GSTM1-1 and GSTT1-1 protein, respectively, confer greater protection from cruciferous vegetables in individuals with these genotypes. Similarly, we have shown in a controlled dietary trial that levels of GST-alpha-induced by ITC-are higher in GSTM1-null individuals exposed to cruciferous vegetables. The selectivity of glucuronosyl conjugation of flavonoids is dependent both on flavonoid structure as well as on the UGT isozyme involved in its conjugation. The effects of UGT polymorphisms on flavonoid clearance have not been examined; but polymorphisms affect glucuronidation of several drugs. Given the strong interest in the chemopreventive effects of flavonoids, systematic evaluation of these polymorphic UGTs and flavonoid pharmacokinetics are warranted. Overall, these studies suggest that for phytochemicals that are metabolized by, and affect activity of, biotransformation enzymes, interactions between genetic polymorphisms in the enzymes and intake of the compounds should be considered in studies of cancer risk. Genetic polymorphisms in biotransformation enzymes may account in part for individual variation in metabolism of a wide range of phytochemicals and their ultimate impact on health.

Background and Purpose Various imaging paradigms are used for endovascular treatment (EVT) decision-making and outcome estimation in acute ischemic stroke (AIS). We aim to compare how these imaging paradigms perform for EVT patient selection and outcome estimation. Methods Prospective multi-center cohort study of patients with AIS symptoms with multi-phase computed tomography angiography (mCTA) and computed tomography perfusion (CTP) baseline imaging. mCTA-based EVT-eligibility was defined as presence of large vessel occlusion (LVO) and moderate-to-good collaterals on mCTA. CTP-based eligibility was defined as presence of LVO, ischemic core (defined on relative cerebral blood flow, absolute cerebral blood flow, and cerebral blood volume maps) <70 mL, mismatch-ratio >1.8, absolute mismatch >15 mL. EVT-eligibility and adjusted rates of good outcome (modified Rankin Scale 0–2) based on these imaging paradigms were compared. Results Of 289/464 patients with LVO, 263 (91%) were EVT-eligible by mCTA-criteria versus 63 (22%), 19 (7%) and 103 (36%) by rCBF, aCBF, and CBV-CTP-criteria. CTP and mCTA-criteria were discordant in 40% to 53%. Estimated outcomes were best in patients who met both mCTA and CTP eligibility-criteria and were treated with EVT (62% to 87% good outcome). Patients eligible for EVT by mCTA-criteria and not by CTP-criteria receiving EVT achieved good outcome rates of 53% to 57%. Few patients met CTP-criteria and not mCTA-criteria for EVT. Conclusions Simpler imaging selection criteria that rely on little else than detection of the occluded blood vessel may be more sensitive and less specific, thus resulting in more patients being offered EVT and arguably benefiting from it.

Salinity Effect on the Equilibria and Kinetics of the Formation of CO₂ and R-134a Gas Hydrates in Seawater

Johanna, Lianna,Kim, A Ram,Jeong, Guk,Lee, Jea-Keun,Lee, Tae Yun,Lim, Jun-Heok,Won, Yong Sun Materials Research Society of Korea 2016 한국재료학회지 Vol.26 No.7

Gas hydrates are crystalline solids in which gas molecules (guests) are trapped in water cavities (hosts) that are composed of hydrogen-bonded water molecules. During the formation of gas hydrates in seawater, the equilibria and kinetics are then affected by salinity. In this study, the effects of salinity on the equilibria of $CO_2$ and R134-a gas hydrates has been investigated by tracing the changes of operating temperature and pressure. Increasing the salinity by 1.75% led to a drop in the equilibrium temperature of about $2^{\circ}C$ for $CO_2$ gas hydrate and $0.38^{\circ}C$ for R-134a gas hydrate at constant equilibrium pressure; in other words, there were rises in the equilibrium pressure of about 1 bar and 0.25 bar at constant equilibrium temperature, respectively. The kinetics of gas hydrate formation have also been investigated by time-resolved in-situ Raman spectroscopy; the results demonstrate that the increase of salinity delayed the formation of both $CO_2$ and R134-a gas hydrates. Therefore, various ions in seawater can play roles of inhibitors for gas hydrate formation in terms of both equilibrium and kinetics.

Adaptive Controller for Double-Deck Elevator Systemusing Genetic Network Programming

Johanna Mansilla,Shingo Mabu,Lu Yu,Kotaro Hirasawa 제어로봇시스템학회 2009 제어로봇시스템학회 국제학술대회 논문집 Vol.2009 No.8

In this paper, an improved approach is proposed based on an updating strategy using Genetic Network Programming(GNP) for the controller of Double-Deck Elevator System(DDES). Since the elevator controller has to deal with constant changes of its environment, our approach is proposed to deal with better the environment changes, resulting in a reduction of the waiting time and increasing the transportation capacity. This updating looks for ward to contributing to the efficient adjustment of the system periodically according to the gained system information. The performance of the proposed method is evaluated by comparis on with the conventional GNP method, which does not update the controller. By this evaluation, the enhancement of our model is confirmed.

Wavelength verification of laser through varied slit widths using a single slit diffraction set-up

Johanna G. Bantol,Rizelin John G. Ofelia 국제과학영재학회 2016 APEC Youth Scientist Journal Vol.8 No.2

Being able to behave as a wave, light can be dispersed from its source point using slit/s. This is called single slit diffraction. Using this ability, the wavelength of a certain light source, like laser, can be determined. This is through the working equation: =. Through the CCD (charge-coupled device), the diffraction of the light was seen and using the Vision Assistant Program, the order for the destructive interference was known. The manipulated variable in this research was the usage of different slit widths (0.04 mm, 0.08 mm, and 0.16 mm). It was seen from the experiment that the wavelength is approximately close to the actual one. Even though different slit widths were utilized in the study, the wavelength remained close to the original value. Data analysis was done after the conduct of the study and it was concluded that the smaller the value of the slit width, it became difficult to measure the value of the wavelength due to the larger distance between the destructive interferences but it has a much more precise measurement, which was seen in the calculations of the percentage error.
