The purpose of this research is to analyze characteristics of street elements when pedestrians have a view in the street. The research was utilized eye-tracking experiment and two times survey before and after experiment. The experiment is composed as follows. The data collection was conducted two days period from March 30 to 31, 2017. There were 43 participants who were all male and undergraduate students. In the data recording, the stimulus image was presented 65 seconds on a 23-inch monitor. Prior to analyzing data, the images were represented into five elements of AOI(area of interest). The fixation rate was divided by a period such as 'fixation time' and 'fixation count' parameters. The results were additionally obtained by linking analysis with the area ratio of AOI, time series analysis, and questionnaire. First of all, both building signs and advertisement standing boards draws attentions in participants. From a comparison between fixation rate and survey, the data have negative perspective view. Second, the advertisement standing boards are more eye-catching than other elements regardless of AOI size. It shows the priority of elements what should be developed in the environment. Third, the pavement is rarely seen in the fixation rate. Fourth, the trees are not a long frequency but viewed as a positive element. People want to keep the natural site in the street. In summative research, this method of extracting eye movement data would be provided a foundation data for developing streetscape plan based on scientific factors.

The purpose of this study was to make a comparative analysis of nursing students interest in health matters concerning themselves and compare it to non-nursing students. The results were to be categorized and used as health content recommendation when organizing health curriculum and planning health education programmes. The instruments used this study were 'The Health Inventory and The Health Need Inventory introduced to 80 items from 125 items by Lee in Korea(1980). There was a very high correlation between the 125 items and condensed 80 items (r=0.9508, t=11.0643. p<.001). The convenience sample was chosen from 226 nursing students and 204 non-nursing students in the departments of humanities of college in Inchun and Ansan from March 4 to April 5. 1996. Data were analyzed by the SAS computer Program. The results are as follow: When comparing health interest of nursing student group with non-nursing student group, total group mean of nursing students was significantly higher than that of non-nursing students (t=2.977 p<.01). But the rank order of the nursing student group was similar to that of the non-nursing group. and what nursing student felt interested was coincident with what non-nursing students felt as being necessary. The most interested health area between nursing student and non-nursing students were ${\ulcorner$personal hygiene & grooming${\lrcorner}$ ${\ulcorner$weight control${\lrcorner}$, ${\ulcorner$sex education${\lrcorner}$ ${\ulcorner$mental health${\lrcorner}$. On the other hand the least interested health areas were. ${\ulcorner$smoking and health${\lrcorner}$ ${\ulcorner$alcohol and health${\lrcorner}$, ${\ulcorner$drug and narcotics${\lrcorner}$ In non -nursing students but in nursing students ${\ulcorner$structure and function of body${\lrcorner}$, ${\ulcorner$dental health${\lrcorner}$ ${\ulcorner$safety${\lrcorner}$. Comparing students health interest by major In college, total group mean of nursing students is significantly higher than that of non-nursing students in 14 health areas including ${\ulcorner$community health${\lrcorner}$, ${\ulcorner$control and prevention disease${\lrcorner}$ ${\ulcorner$consumer health${\lrcorner}$ ${\ulcorner$family health${\lrcorner}$ ${\ulcorner$mental health${\lrcorner}$ ${\ulcorner$personal hygiene and grooming${\lrcorner}$ ${\ulcorner$safety${\lrcorner}$ ${\ulcorner$structure and function of body${\lrcorner}$, ${\ulcorner$sex education${\lrcorner}$ ${\ulcorner$alcohol and health ${\lrcorner}$ ${\ulcorner$ drug and narcotics${\lrcorner}$ and ${\ulcorner$smoking and health${\lrcorner}$ The following recommendations could be made considering the above mentioned factors: 1. The priority of health content should reflect the items to the highest interest area of students and highest need area of adults. 2. The health items which were significantly different in the area of health interest, by major, should be used in planning health education programmes and organizing health curricula.

In this study, we have observed the change of the Hounsfield (HU) in the alteration of by changing in size of physical area and setting size of region of interest (ROI) at focus on kVp and mAs. Four-channel multi-detector computed tomography was used to get transverse axial scanning images and HU. Three dimensional printer which is type of fused deposition modeling (FDM) was used to produce the Phantom. The structure of the phantom was designed to be a type of cylinder that contains 33 mm, 24 mm, 19 mm, 16 mm, 9 mm size of circle holes that are symmetrically located. It was charged with mixing iodine contrast agent and distilled water in the holes. The images were gained with changing by 90 kVp, 120 kVp, 140 kVp and 50 mAs, 100 mAs, 150 mAs, respectively. The 'image J' was used to get the HU measurement of gained images of ROI. As a result, it was confirmed that kVp affects to HU more than mAs. And it is suggested that the smaller size of physical area, the more decreasing HU even in material of a uniform density and the smaller setting size of ROI, the more increasing HU. Therefore, it is reason that to set maximum ROI within 5 HU is the best way to minimize in the alteration of by changing in size of physical area and setting size of region of interest.

The contrast limited adaptive histogram equalization(CLAHE) is an advanced method for the histogram equalization which is a common contrast enhancement technique. The CLAHE divides the image into sections, and applies the contrast limited histogram equalization for each section. X-ray images can be classified into three areas: skin, bone, and air area. In clinical application, the interest area is limited to the skin or bone area depending on the diagnosis region. The CLAHE could deteriorate X-ray image quality because the CLAHE enhances the area which doesn't need to be enhanced. In this paper, we propose a new method which automatically determines the clip limit of CLAHE's parameter to improve X-ray image quality using fuzzy logic. We introduce fuzzy logic which is possible to determine clip limit proportional to the interest of users. Experimental results show that the proposed method improve images according to the user's preference by focusing on the subject.

This study investigated price factors for large apartment complexes in Seoul during the COVID-19 pandemic and compared Gangnam and non-Gangnam areas, which have been recognized as heterogeneous markets. We find that the change in apartment prices in large-scale complexes did not significantly affect the individual characteristics of apartments, unlike previous studies, but was affected by macroeconomic variables such as interest rates and money. On the other hand, considering the units of the interest rate and total monetary volume variables, the effects of two variables on the apartment sales price is significantly high. In addition, the Gangnam area model analysis shows that apartment prices are greatly affected by interest rates and currency volume, and, the non-Gangnam area model analysis shows that apartment prices are greatly affected by interest rates and currency volume, but the degrees are different from the Gangnam area model. Overall, our study shows that interest rates and money supply were the main factors of apartment price changes, but apartment prices in non-Gangnam areas are more sensitive to changes in interest rates and money supply.

This study assessed the beauty care behavior and the dietary attitudes, eating behaviors, and dietary quality related to beauty care in accordance with the level of interest in beauty care by examining 558 female high school subjects in the Incheon area. The study aimed to identify the interest in beauty care on the part of adolescent girls that impacts their dietary life and provide basic data for nutrition education forming desirable dietary habits. The interest in beauty care on the part of female high school students is relevant to dietary life and dietary attitude, with the high-level interest group attempting to use diet foods more frequently and attempting weight control because of their low satisfaction with their body type. On the other hand, a high level of interest in appearance failed to lead to the practice of a varied and balanced dietary life. Therefore, nutritional education is necessary to avoid a high level of interest in beauty care, leading to an incorrect perception of body shape and excessive weight control. Furthermore, nutrition education is necessary to link interest in appearance to the beauty of a healthy body based on nutritional balance by connecting the interest in appearance to a varied and balanced dietary life that goes beyond the category of practice.

With CB data in South Korea, this study examines whether the credit risk of borrowers changes when the regulation on bank mortgage supply is relaxed. We analyze the effect of deregulation on LTV and DTI limits in the Seoul-metropolitan area in August 2014 with a difference-in-difference approach. We find that the probability of delinquency is lower in the Seoul metropolitan area after the deregulation than in other urban areas. The effect is noticeable among low-income and low-credit borrowers. We also find that borrowers change their debt structure to reduce the interest costs utilizing their improved access to bank mortgages. The findings suggest the necessity to consider the burden of the high interest costs of unsecured loans for debtors with low incomes and low credit ratings in designing housing finance regulations.
