When observing an object in a space, a part of it is remembered into our perception in the time for paying attention or conscious observation and it reaches to our visual understanding. In this study, it examined characteristics by each subject through the process of visual understanding by changes in such observation time. The results from this study are summarized as belows: First, through analysis of the observation data focused on the distance between the observed points, it was able to apply those visual theories organized before to the analysis of characteristics of the time for understanding by each subject. Second, there showed big differences in the time for visual understanding by each subject according to changes in the observation time so that it was found that there were big differences according to the characteristics of subject's intention or purpose of the observation of a space. Third, as the number of continuous observation gives an important clue in judgement of how well the space was understood, it was able to compare and organize the mutual characteristics of the time the attention was concentrated, the time observed intentionally and the time understood visually. Fourth, it was found that the shorter subjects gave the intentional observation in observing a space, the longer they spent the time for paying attention, while the less they could understand it visually.

With the help of this study, we aim to investigate the influence of Financial Distress (FD) and information and communication technology (ICT) on the operating performance and efficiency of banks in the Indian banking sector. FD can be defined as a position in which a company or individual is not in a condition to fulfill their promise of paying their obligations on time. The term "financial distress" refers to a situation in which a corporation or individual is unable to keep their promise of paying their debts on time. In this work, panel data analysis (PDA) was used to analyze data from 33 Indian banks over ten years (2010 to 2019). According to the findings, FD has a positive and significant impact on bank operational performance and efficiency. The current study will give the banking industry a better understanding of how a bank's performance can be negatively impacted by distressing conditions that render it inefficient and ineffective. Second, it will show investors how the level of distress can have a significant impact on bank performance in the market, finally resulting in the loss of money invested.

Rapid economic development has led seafood consumption to its quality - oriented pattern as well as consumer's in China. This study concerns about The First, China is Seafood development background. The Second, China become emboldened seafood causes. The third, seafood consumption has characteristic. The fourth, seafood consumption has the organization of society. The study shows that there are economic developmental periods Chinas has three time. The First time$(1961\sim1983)$ is rapid growth. The Second time$(1984\sim1998)$ is growth accumulate. The third time$(1999\sim)$ is changing on seafood consumption as the consumption of seafood is changed according to economic variables changes in income, price, tastes and population. This changing pattern of seafood consumption is based on economic variables appears toward luxury and convenience seafoods. Consumption of food is also affected by non - economic variables. The most typical non - economic variables leading to changes of seafood consumption is local, seafood culture, $et{\ldots}$ Recently seafood consumption pattern shows that consumers paying more money to get their seafood preference for pursuing its hight growth and varienty.

The study on correlation between the parents' character of orthodontic patients and patients cooperation. Although dentists have excellent skill and technique, patients' cooperation is always demanded. Patients' poor cooperation results in poor treatment result. Cooperation between psycho-social state of parents and patient's cooperation was studied. The parent's psychosocial state is evaluated with scl-90-r. The cooperation is measured by appointment time compliance, appliance taking rate, breakage of appliance, and fee paying. Parents' psychosocial contents are somatization, obsessive-compulsive, interpersonal sensitivity, depression, anxiety, hostility, phobic-anxiety, paranoid ideation, psychoticism, and additional item. Statistics was done by SPSS WINDOW version 12.0 program. The result showed no correlation between patients' cooperation and their parents' psychosocial state. There is no correlation between father's psychosocial state and patients' cooperation except psychoticism. There is no correlation between mother's psychosocial state and patients' cooperation. However, there was correlation among cooperation variables: appointment time compliance, appliance taking rate, breakage of appliance, cost paying. Appliance taking rate and cost paying showed positive correlation. Our findings suggest that patients' cooperation does not followed their parents' pychosocial state. Other combined factors should be considered like pychosocial state of patient and doctor-patient relationship.

The part-surface of mold or stamping-dies consists of a compound surface which consists of lots of composite surfaces, and may have various types of feature shapes including convex sharp edge (CSE). Those CSE features should be considered with care in machining the surface, which necessitates extraction of CSE curves on a compound surface. This work can be done rather easily for a solid model which has a complete topology information. In case of the compound surface without topology information, however, such CSE curves must be gathered through some geometrical calculations paying much computation time. In the paper, extracting CSE curves by the construction of a CSE region-map which can reduce time, and detecting various common edge types are presented.

This paper presents a discrete time optimal asset buying problem with a predetermined final deadline where an available budget is limited. A cost is paid to search for assets called the search cost. A seller who shows up offers a price for the asset and then the buyer decides whether or not to buy the asset by comparing the offered price to his optimal selection threshold. When the budget becomes less than the search cost or the price of the asset the buyer can get a necessary loan with some interests. We clarify the properties of the buyer's optimal selection threshold in order to maximize the expected value of budget which is left after paying all the search costs and the price of the asset at that point in time.

Recently, the advanced development of smart devices has increased the interest in health-care, and many people are paying more attentions to disease prevention than disease treatment. Among these prevention methods, the bare body movement has received much attention, and especially walking exercise is attracting much attention because it is enjoyable without any restrictions on place and time. Walking exercise is generally divided into two types: walking on the ground and climbing the stairs. Walking up the stairs consumes much more calories compared to walking on the ground. These walking exercises have the advantage that they can be easily performed by male and female without special equipments or economic considerations. However, there is a lack of applications and systems that accurately determine such walking and stair walking and measure momentum according to stair walking. In this paper, we designed and implemented a real-time walking status analysis system using smartwatch's, pedometer, smartphone's barometer and beacons.

This research studies how women's hourly wages affect childbearing using data from the National Longitudinal Survey of Youth. The results of discrete time hazard model show that the relationship between women's hourly wage and fertility is dynamic. Overall relationship looks negative, but they are not consistent across education levels. Women who have a high school diploma or less have a tendency to decrease childbearing when their wages increase. But women who have some college experience or a college degree are likely to have children when their wages increase. It means that only for highly educated women who are likely to be in high paying decent jobs, the rise of income can be used as a resource for reconciling the mother's and worker's roles. Or, for less educated women who are likely to be in the low paying jobs, the rise of income is not large enough to lessen role incompatibility.

Traditional carrier-based PWM method cannot produce maximum output voltage due to dead-time compensation, w which results in degradation of voltage utilization factor compared with ideal PWM inverters, Dual-carrier PWM has b been proposed as an alternative method to solve this problem. But this method requires paying attentition to changing r reference voltage in the vicinity of maximum voltage to ensure enough dead-time. Novel dual-carrier PWM method and i it's practical implementation is proposed in this paper. The reference voltage can be changed without any restriction in t this method.
