This study was conducted to assess meal management and nutrient intake of 357 elderlies in Ulsan. 114 male and 243 female elderlies over 65 year old were recruited from July 5 to August 13, 1995. Questionnaires for general characteristics of the subjects(such as family size, living cost, pocket money and health condition) and for meal management were used. The levels of depression and anxiety were measured by CED-S and Spielbuger's STAI-S, respectively In addition, nutrient intakes were conducted by convenience methods. Nutrient intake of male and female showed the average daily intake of energy, Protein, vitamin A, vitamin $B_2, $ and vitamin C were lower than Korean recommended dietary allowances(RDA). But other nutrient intake were higher than RDA except that calcium intake of female was lower. Most nutrient intakes were positively correlated with family size, living cost, pocket money and health condition. Depression and anxiety scores were also negatively correlated with most of nutrient intakes. The pattern of meal management could predict nutrient intakes as expected : regularity and pleansantness of eating were positively correlated with nutrient intakes, whereas unbalanced meal and eating lonely were negatively correlated with them.
The purpose of the study was to investigate the effect of self-esteem, depression, and social support on suicidal ideation in university students. A self-reported questionnaire was completed by 220 university students from September to November 2015. The study instruments comprised self-esteem, depression, social support, and suicidal ideation. The data were analyzed by descriptive statistics, t-test, ANOVA, Pearson's correlation coefficients, and multiple linear regression using SPSS/WIN 21.0 program. The result showed that the difference of suicidal ideation by general characteristics was significant in major satisfaction(F=5.222, p=.006). The significant factors influencing suicidal ideation of university students were self-esteem(${\beta}=-0.227$, p=.004), depression(${\beta}=0.211$, p=.006), social support(${\beta}=-0.140$, p=.045), and with the explanation power of 21.9%. To decrease suicidal ideation of university students, it is necessary to develop a program increasing the self-esteem and managing the depression. The interest and social support of them will help the healthy promotion of university students.
The purpose of this study is to measure the relation of employment stress and self-esteem in some health college students and to consider a proper means for the solution. The population of the research is some randomly chosen health college students located in Seoul City during the period from May 10 to June 11 2010, and the sample of 295 students were recruited as the analysis object group. The data on general characteristics and employment stress were collected by a questionnaire survey. The collected data were analyzed with the SPSS WIN 12.0 program. The following shows the results of this study. 1. Employment stress was low in high group of satisfaction in campus life. It was statistically significant(p<0.001). 2. Mean scores of total self-esteem in study population were 3.1 and positive self-esteem level(3.76) were higher than negative ones (2.44)(p<0.001). 3. The relation between employment stress and selfesteem(r=0.132) revealed significant correlation. 4. In regression analysis, home economy, competence for a schoolwork, satisfaction in campus life, self-esteem(p<0.001) were proved as significant factors that is related to the employment stress. In other words, It is significant statistically that the lower home economy, competence for a schoolwork, satisfaction in campus life, self-esteem, the higher employment stress level. I suggest with the result of the study that for coping effectively employment stress of health college students, we will need to open an educational development considering self-esteem and an exclusive employment counsel window for better administrationwelfare service in campus, to expand industry-academic cooperation in community. Because of students are independent responsibility of employment, active effort must take precedence in order for the solution of problem by themselves. Also, we will need to create better academic environment and show more concern, consideration, love in family.
This study aims to develop and apply the language education program model - based on balanced language education approach - on development of literacy of young children in low-income families, specially participating in Dream Start public welfare service. Development of this languge education program was based on the basic view and characteristis of balanced language education. It was progressed in accordance with Analyze-Design-Develop-implement-Evaluate(ADDIE), which is an widely-used instructional design model. Educational contents including reading skills of picture books based on whole language approach and well-structured reading and writing sequences, teaching and learning method including the principles and the strategies and teaching and learning systematic evaluation method are proposed in viewpoint of balanced language teaching approach. The application of the program was conducted targeting 20 young children participating in Dream Start welfare service from June 2015 until early November. To evaluate the effectiveness of this program, word reading inspection and nonsense word reading inspection developed by Ko, Yeon-Kyung(2002) were performed. The reflective thinking journal of visiting teachers and the satisfaction reported by parents were analysed in the qualitative research method. As a result, reading skills of young children were improved. The superiority of the program - prefernce for the picture book, interests in written languages, effectiveness of individualized language education method - was demonstrated by qualitative analysis of reflective journal. This study has the significance on presenting the executable language education model for literacy development of young children in low-income families based on balanced language education approach.
This study reports on initial founder performance and satisfaction that is affected by mentoring skills and mentoring functions. Through the empirical analysis, seen the initial founder performance and satisfaction as a respective dependent variable, this study intends to provide efficient direction of the responsibility mentor and present a method that enhances the survival of the initial start-up founder. The frequency analysis was conducted to determine the general characteristics of the sample, by leveraging the statistical package SPSS 20.0 for Windows program, details of the items measuring tools present a statistical analysis of sample data, 120 people have gathered in the survey data for this factor analysis was performed with a correlation to classify each region was calculated to Cronbach's ${\alpha}$ factor to determine the reliability of the measurement tool, and tested the hypothesis using linear regression analysis for verification. Was found to play an important role to draw the founder and mentor mentoring skills and capabilities in early stage start-ups, and conclusions drawn from this process. In particular, modeling of the mentor with a sound mind and behavior brought the better performance and satisfaction of the initial start-up founder. If a mentor provides mentoring with more interests in career development and psychosocial functions of the mentoring functions, it is seen to be more efficient way to improve survival rate of initial start-up as well as increasing a founder's performance and satisfaction.

This was a descriptive survey to determine the intention of users to use smartphone healthcare applications (SHAs) and to clarify factors that may influence such intention. The data were collected during the month of April in 2015, using a structured self-report questionnaire that was distributed to 300 participants aged 20 to 70 years; 285 complete copies were used for the final analysis. The data were analyzed using descriptive statistics, independent t-test, one-way ANOVA, Pearson correlation coefficients, and hierarchical multiple regression. First, according to the results, the average intention to use SHAs was 3.28 out of 5, which varied according to age, final education, economy level, vacation, current disease, total period of smartphone use, and etc. Second, significant correlations were shown by exercise behavior, dietary management behavior, stress management, satisfaction with smartphone use, and satisfaction with using SHAs. Third, the explanatory power of the predictive model involving all general, health-related, smartphone use-related, and SHA use-related factors was 45.5%; and the economic level, interest, status, and awareness satisfaction of patients using SHA were identified to be the main influential factors. The results indicate that SHA developers need to put efforts into improving consumers' app recognition and to develop plans in provoking consumers' interests to increase the use of SHAs.

Earthquakes over 5.0 on the Richter scale have recently occurred in Korea, which has led to interest in the seismic safety of structures. If a water storage facility is damaged by an earthquake, the water could leak, and the insufficient water would make fire suppression difficult. Therefore, a water storage facility should satisfy safety requirements for earthquakes. In this study, the seismic performance of a water tank was improved by installing a lead rubber bearing between the foundation and the tank. It designed the lead rubber bearing available to the existed concrete foundation. ANSYS was used for modeling to consider the interaction between the fluid and structure of the tank and the hydrostatic and hydrodynamic pressure using four seismic waves. In the case of hydrostatic pressure at 2.5 water level, full level, the same stress appeared irrespective of whether the seismic isolation was installed. When hydrostatic pressure and hydrodynamic pressures are applied at the same time, the seismic-isolated water tank showed less seismic force, and the damping ratio was lower than that of general seismic isolation. This occurred because the weight of the water tank is much smaller than the stiffness of the seismic isolation. The result is expected to be used for further research on seismic capacity evaluation for water tanks.

To obtain a fruitful outcome in intellectual property (IP) education in colleges, it is essential to identify the affecting factors. The relationships between the factors were to be analyzed as a structural equation model. The IP education achievement was measured by the IP total score. The students' characteristics (input factor) were measured by defining the characteristics, parents' expectations, and IP interest. The characteristics after highschool (process factor) were observed as college satisfaction and learning attitude. Students with excellent defining characteristics have not only high college satisfaction but also an excellent learning attitude, so they have a high IP total score. Using indirect effects analysis, the path through which the defining characteristics indirectly affects the IP total score through college satisfaction and learning attitude was identified. This is consistent with the prediction that self-directed students will have high participation in IP classes and achieve excellent results. The IP interest was found to have no significant effect on the IP total score. This contradicts the belief that students with high IP interest will actively participate in IP classes and earn high scores, which is because it overlooks the possibility that participation in IP activities in high school is semi-forced.

Due to the impact of COVID-19, people are paying attention to convenience and health, and the use of IoT devices to help them is increasing. In order to embed a lightweight security element in IoT devices that need to handle sensitive information even with limited resources, the development of a lightweight S-box is essential. Until 2021, it was common to develop a lightweight 4-bit S-box by a heuristic method, and to develop an extended structure or repeat the same operation for a larger size lightweight S-box. However, in January 2022, a paper that proposed a heuristic algorithm to find an 8-bit S-box with better differential uniformity and linearity than the S-box generated with an MISTY extended structure, although non-bijective, was published [1]. The heuristic algorithm proposed in this paper generates an S-box by adding AND operations one by one. Whenever an AND operation is added, they use a method that pre-removes the S-box for which the calculated differential uniformity does not reach the desired criterion. In this paper, we improve the performance of this heuristic algorithm. By increasing the amount of pre-removal using not only differential uniformity but also other differential property, and adding a process of calculating linearity for pre-removing, it is possible to satisfy not only differential security but also linear security.
The study attempted to identify the factors affecting the image of nurses in health and non-health university students after COVID-19. The study was collected from November 15, 2021 to 2011 and 28th, 2021, from 133 health-related and 123 non-health-related students in four universities. This data was analyzed by descriptive statistics, correlation, and multiple regression analysis using the SPSS 22.0 program. As a result of the study, whether the nurse image according to general characteristics is in the first grade of health-related college students(t=2.82, p=.006) showed a statistically significant difference. The nurse image of college students showed a positive correlation with the mass media image and major satisfaction in both health and non-health fields. For health-related college students, the image of mass media, major satisfaction, and first grade influence the image of nurses (F=40.42, p<.001)In the case of university students in non-health departments, it was found that only the media image affects the nurse image. (F=20.13, p<.001). In order to improve the image of nurses, it is necessary to have continuous interest in contact with the media through new media and to approach it systematically.
