Over the past half century, satellites have continuously expanded their roles in remote sensing applications. As the number of satellites to be launched are expected to continuously increase in coming years, the research on satellite payloads will be in high demands. Earth Observation (EO) satellites are nowadays widely utilized for various purposes. Especially, Agriculture and forestry applications are considered as their major application areas. Since about 85% of domestic land cover is classified as forest or cropland areas, it would be reasonable to suggest that the demand for these satellites should be of high priority. In this paper, a comprehensive analysis is performed on the technical specifications of satellite payloads that may be applicable to agricultural applications. We attempted to build a solid database on payload specifications by collecting relevant information available from various related institutes and academic research works. A number of experts involved in national agricultural research and satellite development programs have been invited to investigate required payload design. Based on the current technology development status and future plan, multiple options for future satellite payload designs have been suggested bearing in mind that the results may be applicable to the future agriculture and forestry satellite payload design. The proposed payload specifications are analyzed in depth through satellite operation simulations under the mission of observing the national agriculture areas. The proposed design scheme and simulation results may be used as technical references to satellite payload design for future space missions.

Objectives: This study aims at analyzing relationships between college life adoption, self-efficacy, and self-esteem in undergraduates majored in dental hygiene to explore the ways to prevent college dropouts and promote and support college life adaptation. Methods: This study was made with the use of a self-completion questionnaire with 200 undergraduate students, aged 19 or older, majored in dental hygiene in three colleges situated in Gyeonggi-do, from September 02 to 11, 2019. The results were analyzed using the SPSS Program Version 22.0. Results: First, the degree of college life adaptation in undergraduates majored in dental hygiene was found to be the highest, in those who were under 20 years old and first grade, decided to major in dental hygiene because of 'its aptitude and future career', and graduated from general high school and with a high economic level. Second, the degree of college life adoption was found to be the highest in the third grade in terms of social adaptation, and of the first grade was higher than the second grade. Third, as for the degree of attachment to college, it was revealed to be the highest in those decided to major in dental hygiene because of 'its aptitude and future career', and the degrees of academic adaptation, emotional adaptation, and attachment to college were found to be higher in general high school graduates than specialized high school graduates. Fourth, the factor having the most significant influence on college life adaptation in undergraduates majored in dental hygiene was found to be self-efficacy, followed by self-esteem and economic level. Conclusion: From these results, it is possible to assume that when developing programs to prevent college dropouts in undergraduates majored in dental hygiene, it should consider their high schools, school grades, and motivations to decide to major in dental hygiene. In addition, in order to take an educational approach to raise self-esteem and self-efficacy in career decision making to raise the degree of college life adaptation.

The purpose of this study is to investigate the influence of the parents' rearing attitude perceived by high school students and students' covert narcissism on the adjustment of high school students. For that, research data are collected from 580 high school students in Busan. 524 students' data are analyzed through SPSS Ver. 21.0 to examine correlations and influences of parents rearing attitude, students' covert narcissism and adjustment ability to schools. The results obtained in this study are as follows: First, the finding shows that the adjustment of high school students has a significant static corelation with parents' rearing attitude which is perceived by students. Second, affective attitude of parents' rearing attitude, has the strongest influence on students compliance in school. In addition, goal-oriented and rational attitude of parents has an impact on students' scholastic aptitude and academic achievement. Third, students' goal-instability of life which is one element of students' covert narcissism has negative effect on overall students' school life. Thus, these results suggest that for a better adjustment of high school students, various parent education training and development of programs that can help students set up goals are needed. It also highlights the importance of counseling.

As many countries in the world including the Republic of Korea have used all their national resources in the accelerating economic information warfare, illegal leakage of industrial technologies and information has increased rapidly. The costs required for damage prevention from 2007 to 2008 are estimated at approximately KRW 180 trillion which is expected to increase gradually in future. Because the tricks of leaking key technologies are also getting increasingly systematized, sophisticated and bigger, e.g., simple theft at the individual level or the conspiracy of all the staff taking part in the research activities, we should pay special attention to technology security in addition to technology development. While there are several factors affecting such the brain drain, they usually include personal, social, political and cultural factors, for instance, very heavy educational expenditure of children compared to relatively low pay, the speedy labor market circulation for experienced personnel, or political restrictions on researches. In this context, as part of efforts made to prevent the outflow of core personnel, individual companies and research institutes should establish systematically appropriate core personnel management systems for their own organizational or business goals and principles which are intented to ensure to give better treatment and benefit to core personnel and to exercise closer supervision over them. Furthermore, the conventional personnel management system should be radically and flexibly improved in the manner of encouraging the core personnel returning to the organization to combine their external experiences with practices, instead of penalizing them. At the same time, it is necessary to train and educate core personnel through mutual collaboration and in-house training facilities as well as external academic programs operated jointly at the level of the industry. Finally, as the issues concerning the outflow of core personnel are not just problems of relevant companies and other advanced countries have devoted their best efforts to secure their own key technologies at the national level, it is urgent for the industry and the competent authorities to cooperate closely.

Objectives : The purpose of this study was to verify the impact of the empowerment of dental personnels as one of variables affecting the performance of dental institutions and to seek ways of boosting their organizational productivity. Methods : The subjects in this study were dental personnels who worked in dental institutions. After three investigators were trained, a pilot survey was conducted from October 20 to November 20, 2009, and the questionnaire used in the pilot survey was finalized. The collected data were analyzed with a SPSS(Statistical Package for the Social Science) WIN 12.0 program. The findings of the study were as follows: Results: 1. The dental personnels investigated got 3.98 in meaningfulness, one of the empowerment factors. They found a meaning in their job when they performed it. 2. The dental personnels who were older were more excellent in self- determination and influence, and age made a significant difference to their empowerment. 3. The dental personnels who were better educated were more superior in terms of empowerment, and academic credential made a significant difference to their empowerment factors was statistically. 4. The dental personnels whose yearly salary was larger were more which were the factors of empowerment of each factor was statistically significant. 5. Dental health agency workers less than three years accounted for most of 152 people were working longer duration of empowerment as a whole was that each of the factor scores. Empowerment of each factor was statistically significant. 6. The dental hygienists made up the largest group among the dental institution employees, and the kind of occupation made a significant difference to meaningfulness, competency and influence, which were the factors of empowerment. 7. The greatest group of the dental personnels worked in dental clinics, and the dental hospital employees surpassed the dental clinic employees in competency, self-determination and influence. There was a significant difference in the influence factor according to the type of dental institutions. Conclusions : Thus, the dental personnels were more aware of the meaningfulness factor when their perception of the job-related empowerment was checked, and it indicated that most of them attached importance to meaningfulness during their job performance. But just employees who worked in dental institutions located in particular regions were examined, the findings might not be generalizable. In the future, more extensive research should be implemented, and the sorts of programs that could stir up empowerment among dental institution employees or bolster organizational empowerment should be developed.

Objectives : In order to provide basic data necessary for developing oral health education plane for school continued oral health education by understanding knowledge and activities of oral health. Methods : This study was performed against 324 students at 5th grade of 2 elementary schools in Iksan-si, Jellabuk-do selected through convenience sampling, who were in mixed dentition period that might experience dental caries of permanent tooth. Results : As results, For the knowledge level on oral health by questions, it was found that the case that the elementary school students had correct knowledge on oral health was 'chocolates, snacks, and candies were foods that might often cause dental caries' and 95.8% of the students recognized it well. It was found that for 'must do toothbrushing before going to bed', 'during toothbrushing, I clean my tongue', and 'Proper time necessary for toothbrushing is about 3 minutes', 89.3%, 93.2%, and 89.3% of the students knew the, respectively. When oral health knowledge level by groups was divided into 3 groups and observed, they were classified into Low (0-4 points), Mid (5-7 points), and High (8-10 points). It was found that the knowledge level of each group was High 64.1%, Mid 33.9%, and Low 2.0% and it was identified that the high group took the largest ratio. It was suggested also for oral health knowledge level depending on their father's academic background that there was a statistically significant difference in the group higher than university graduate(p<.05). It was found for oral health knowledge level depending on parents' dental condition that an answer that both parents were good was high and there was a statistically significant difference. But post-analysis resulted that there was no apparent difference among groups. It was found that the ratio of respondents who answered for toothbrushing method 'toothbrush should be moved and rotated downward for the upper teeth and upward for the lower teeth to clean the teeth and gum' were 33.2% of male students and 29.4% of female students and showed statistically significant difference (p<0.05). It was found also that the ratio of respondents who answered to use a toothbrush for about 3 months' were 29.4% of male students and 25.5% of female students and showed statistically significant difference (p<0.05). Conclusions : Oral health program through the elementary school students and their parents for the development of proper oral health care education programs continue to be made should be considered.

Moral education is essential to the military in fostering elite warriors to have clear sense of their nation and the security, while arming themselves with military spirit that strives for victory. To reach this goal, various moral education has been set forth through boot camp training, academic education, unit training, etc. depending on various subject and supporting agencies in question. Also, in order to heighten the effect of the education, various attempts to combine concert-style cultural activities with the programs are carried out. However, the ultimate goal for this moral education is to facilitate soldiers to voluntarily set their minds and will in combat, and the current education system lacks that motivation as it concentrates mostly on educating knowledges about nationality and security. Under such circumstances, various units have attempted to raise morality in creating many public and media activities within the unit, which proven to be successful. In theory, the usual definitions in the field of education such as emotion, interest, attitude, and personality can be expanded upon with public and media activities. With this in mind, we have researched on how effective this method is by conducting various public and media activities in multiple units, total of 531 soldiers, starting from June to July of 2016. As a result, these activities brought positive effects on young soldiers to build pride in their assigned units, and also increased their willingness to carry out their assignments and missions. Through this research, we drew to the conclusion that unit-level public and media activities, which was solely used for gaining trust and communicate with the general civilians, can be used to boost the soldiers moral strength and help them express the strength in action.

This study was conducted to explore the degree of female nursing student's dietary behavior, self esteem, dietary self-efficacy, life stress and the factors influencing dietary behavior of those surveyed. A total of 422 female nursing students in B, C city were surveyed. The data were collected between May 15 and 30 of 2016 and analyzed by a t-test, ANOVA, Pearson's correlation coefficients, and multiple regression analysis using SPSS WIN/21.0. The mean score of dietary behavior was $3.01{\pm}0.49$. In addition, there were significant differences in dietary behavior with respect to grade(F=4.823, p=0.008), residential type(F=6.067, p<.001), academic grade(F=3.907, p=0.021), health status(F=7.975, p<0.001), and degree of health concern(F=4.189, p=0.016). Moreover, there were negative correlations between dietary behavior and self esteem(r=-.238, p<0.001), and dietary self-efficacy(r=-0.438, p<0.001), while there was a positive correlation between dietary behavior and life stress(r=0.194, p<0.001). Regression analysis showed 26.7% of variance in female nursing student's dietary behavior can be explained by dietary self-efficacy, life stress, residental type, and degree of health concern. A follow-up survey investigating various factors influencing female nursing student's dietary behavior is needed and increased dietary behavior education and programs are required.

Objectives : Fatigue is a common symptom experienced by everyone. Nevertheless, clinicians have a tendency of ignoring it since fatigue itself is not considered a distinct disease. Actually, some limited research about chronic fatigue syndrome has been made within the country, but in reality, the probability of getting this syndrome is still considered very low due to the strict diagnosis standard. Therefore, there are tremendous numbers of patients who do not get enough attention from clinicians for their fatigue symptoms only because technically they do not belong to the syndrome. Therefore, a basic statistical database must be compiled and patient management programs must be developed. To accomplish this, we conducted this study by measuring degree of fatigue, clinical characteristics and processes of Oriental medical treatment of fatigue patients. Methods : The objects of this study were selected from the new patients who entered the tonification Clinic in Kynnghee Oriental Medical Center between August 11, 2000 and October 7, 2000. Their main complaint was fatigue and they did not suffer from any physical or mental problem either historically or at the time of the study. The objects were divided into two groups based on duration of fatigue; fatigue under 6 months is considered as acute fatigue and fatigue for longer than 6 months is chronic fatigue. The prepared survey sheet for measuring fatigue degree was distributed to the patients with their consent. The patients were divided again into three subgroups : the fIrst group went through 1st test and constitution test after tonification clinic; the second one went into constitution test skipping Ist measuring test; the third one went into only tonification clinic with neither 1st measuring test nor constitution test. Results : The total number of object patients was 47 and 80% of them were considered as 'fatigue patients' by the Chalder scale. Among all patients, 29.5% requested treatment for chronic fatigue, which is over 6 months. The average of scale II for all patients was 14.8, which indicates moderate fatigue. The averages of scale II-1, II-2, II-3 were respectively 7.5, 5.9, and 3.7 so the most common complaint was physical fatigue. When compared scale II based on occupations, student group scored 6.9 and office man group scored 8.5 in scale II-1, physical fatigue, but it was not significant. Conclusions : Numerous number of patients have come to Oriental medical centers or hospitals in Korea. Therefore, deeper statistical research and follow-up-monitoring are reqnired in the Oriental medical academic world. In this study, among all patients who entered the tonification Clinic in Kyunghee Oriental Medical Center, 29.5% requested treatment for chronic fatigue, which is over 6 months. This kind of statistical report is the first time trial in the Oriental medical academy world. Through these steps, more objective treatment can be made and standards of prognosis assessment can be established.tablished.

Because consumers tend to have negative opinion about a company that neglects social issues like poverty or pollution while it focuses on its own profit, a lot of companies have invested their resources in Corporate Social Responsibility(CSR). CSR has merits of image improving and profit gaining, on the other hand, it has also many shortcomings. First, the cost of CSR may become a heavy financial burden. Specifically, CSR tends to be implemented by a company's unilateral backup, and then this may impose a heavy burden on the company. Second, one cannot expect effects of CSR in a short-term. Because of these shortcomings, the unilateral CSR has gone into alteration of the type of CSR since 1980's. Instead of unilaterality, Cause-Related Marketing(CRM) began to be used for mutual profits among company, consumers, and society. That is, CRM has become to be spotlighted as a new type of CSR. It focuses on partnership between a company and consumers based on cause and mutual profit pursuing through this partnership. So, many contemporary companies prefer CRM activities that derive their positive corporate image, that increase their sales, and that reduce their financial cost. The IBM Matching Grants Program, which is the largest of the IBM-Employee partnership programs, is a typical CRM. This program enables employees and retirees to increase the value of their donations to educational institutions, hospitals, hospices, nursing homes, and cultural & environmental organizations with a matching gift from IBM. Hundreds of educational institutions and thousands of nonprofit organizations have benefited from the contributions by IBM. There might be various types of matching grants. For example, an employee might choose a lump-sum expense or partitioning a lump-sum into a series of small ongoing expenses for his (or her) donation, and a firm might match the employee's total contribution with a lump-sum expense or might match the employee's total contribution with a series of small ongoing expenses. However, it is not easy to find an academic research on which type of matching grant is preferred by employees. This paper shows that an employee prefers the type of matching grants that consists of a lump-sum expense for his (or her) contribution and a series of small ongoing expenses for a firm's contribution [or the type of matching grants that consists of a series of small ongoing expenses for an employee's contribution and a lump-sum expense for a firm's contribution] to the other types of matching grants.
