The purpose of this article is to examine the 'Discussion of maritime defense' which began to be discussed from the late Goryeo dynasty to the early Joseon dynasty and the process of establishing a maritime defense system. Also it can identify changes in the aspects of the naval ship operation and their strategic tactics during the reign of King Sejong. Japanese raiders began a full-scale invasion from 1350 at the late Goryeo Dynasty, So the government realized the need to raise the 'Sea power' and to organize the maritime defense system for defending enemy invasion. for example, the reinforcement of naval forces, construction of warships, develoment of weapon systems and so on. which have achieved remarkable growth while continuing, have also been used to carry out a three-time 'Conquest of Daemado' in 1389, 1396, 1419. Until then, however, it is difficult to interpret that the naval forces had a systematic and organizational combat operation system. According to fighting patterns on combat reports before the early days of King Sejong's reign, Our naval forces had no advantage over the Japanese raiders in terms of their capabilities and tactics. Then, the period of King Sejong marked a watershed in maritime defense history. Based on accumulated experience of naval battles and force Projections, The paradigm shift of the naval strategic tactics for maritime defense has occurred. First, the capability of the naval vessels has improved. for example, ship speed, durability, and weather resistance. Through these efforts, navy forces were able to pursue and attack, destroy enemy's ships by taking advantage of the 'Ship speed superiority'. This has led to tactical shifts from defensive to offensive. Second, purpose to support offensive tactics, the government put a strategic plan into practice that is the forward depolyment of naval bases from the inland to the coast, considering the 'sea environment' and 'threat'. By doing so, Joseon dynasty was able to secure 'the command of the sea'. This may be a little different from the perception of the so-called 'peace period' that King Sejong's era. We need to remember that Joseon dynasty was working hard for its defense. When studying history of maritime defense, these strategic and tactical elements must be fully considered. Only then we can have a coherent understanding of the many naval battles in the past, including the Imjin War(1592-1598).

The aim of this study was to identify the self-confidence in performance and education demand of first aid in kindergarten and daycare center teachers. The data from a questionnaire were collected from teachers in kindergarten and daycare centers from March 5 to 31, 2015. The responses from 149 teachers were analyzed using SPSS 21.0. The results showed that self-confidence in the performance of first aid was mostly low (mean score 2.70), but was significantly high in cases of having a willingness to perform first aid (p=.002). The education demand for first aid was mostly high (mean score 4.04), and significantly high in the case of having experience of emergency situations (4.21, p=.006), and being educated in first aid while working in a childcare facility (4.14, p=.001). Therefore, it is important to educate teachers in first aid regularly after developing an optimized program considering the frequency of emergency situations, and level of self-confidence in the performance and education demand of first aid.

This study was to investigate the factors influencing job satisfaction of nurses in long-term care hospitals focusing on burnout and burden. The participants were 206 nurses recruited from long-term care hospitals in B metropolitan city and C city. Data were collected from January to March, 2014 and analyzed using SPSS WIN 18.0 program. The frequency of experience was $1.65{\pm}0.42$, which is 4~5 times per month and once or twice per week in the problematic behavior in dementia. The frequency of burden was $1.46{\pm}0.48$, which means one nurse can solve the problematic behaviors in dementia. Burnout was $2.53{\pm}0.61$, and job satisfaction was $2.87{\pm}0.45$. Negative correlations were found between burden and job satisfaction (r=-.256, p=.003), and between burnout and job satisfaction (r=-.718, p<.001). A factor influencing job satisfaction was burnout (${\beta}$=-.735), which explained 57%. It is suggested that Intervention programs should be developed to reduce burnout and burden, and to increase job satisfaction for nurses.

This study was performed to compare food consumption patterns, dietary behavior, and nutrition knowledge between Korean professional soccer players and the non-athletic males. Data were collected from 53 soccer players working for Korean professional soccer clubs and 44 non-athletic males, using self-administered questionnaires. There were significant differences in food consumption frequency between two groups. Meats and eggs, fishes and shellfishes, sea weeds were consumed more frequently by the soccer players. The frequency scores of foods rich in iron, calcium, and protein were also higher in the soccer players compared with the non-athletes. Meanwhile, the consumption of alcohol was more frequent in the non-athletes. As for the cooking method, the soccer players showed higher preference for steaming/parboiling and consumed raw vegetables and fruits more frequently than the non-athletic males (p < 0.05). The average scores of soccer players on nutrition knowledge for basic nutrition and athletic nutrition were lower than the respective values of the non-athletic males. However, the soccer players showed better eating behaviors and dietary habits compared with non-athletic males (p < 0.001). They had well-balanced, regular diet and good habits for chronic disease prevention. No significant relationship could be observed with respect to nutrition knowledge and nutritional behavior. Moreover, the experience of getting nutrition information did not affect either nutrition knowledge score or nutritional habits score, except that for habits of chronic disease prevention in non-athletes. Therefore, it is suggested that more effective and practical nutrition education program be needed for promoting healthy eating habits and improving nutritional status in young males.

The purpose of this study was to help improve the quality of education to keep up with fast-changing environments in educating sector. Relevant literature and data were reviewed, and the subjects in this study were dental hygiene juniors at seven two-year colleges in the Seoul metropolitan area and other regions, on whom a survey was conducted for about three months from August through October, 2004, to assess their satisfaction level with their major and educational environments. And it's concluded that in order to attract more new students and foster qualified students, dental hygiene practice labs should be improved on a large scale, and that there should be a great deal of investment in teaching facilities. The major findings of the study were as follows: 1. As for satisfaction with major choice, 57.5% of the students investigated, the largest percentage, expressed satisfaction with their major. 27.8%, the second largest group, found their choice not to be bad. 2. Regarding satisfaction with the state of practice labs, 41.9% were pleased with practice labs. This rate was quite lower than that of nursing students, as 64.2% of nursing students were pleased with their practice labs.7) 3. As to satisfaction with individual practice labs, oral prophylaxis labs were considered most satisfactory, as 53.9% were satisfied with them. Digital radiation labs appeared to be satisfactory the least, which made 77.0% dissatisfied. 4. Whether there were any connections between their working experience as a clinical worker and satisfaction level was investigated. In terms of their satisfaction with major choice and the state of practice labs, the students who had ever worked as a clinical worker were relatively pleased with the state of practice labs. As for satisfaction with each practice lab, those who had ever served as a clinical worker before being admitted into college expressed more satisfaction with radiation practice labs(p<0.05) and digital radiation labs(p<.05) than the others who hadn't. The gap between the two was statistically significant. 5. In regard to the causes of dissatisfaction with practice labs, 93.7 and 80.0% were respectively dissatisfied with digital radiation labs and basic dental hygiene labs because their colleges were devoid of those labs. 51.6%, the largest group, found oral prophylaxis labs unsatisfactory because of their frequent breakdown. In the event of most of the other practice labs, the greatest percentage were discontented due to a shortage of equipment.

This study is based on the theory of salutogenesis, and investigates factors affecting the health status of radiologists who experience high stress and health problems in the rapidly changing medical environment. The study enrolled 379 radiologists working at hospitals in Daegu. A health structure model was established by applying the theory of salutogenesis. Sense of coherence had a direct effect on the health status of radiologists. Psychological stress, social support, and drinking were also influential factors, due to their mediating effect on the sense of coherence. Moreover, social support was also found to be lower when job stresses were higher. Hence, increased psychological stress resulted in lower levels of sense of coherence, social support and exercise. Taken together, results of this study indicate that effects on the sense of coherence have maximum influence on the health status of radiologists, and social support among general resistance resources is an important factor for enhancing sense of coherence. In addition to social support and health behaviors, researches involving various resources and the development of organizational strategies and health promotion intervention programs are required in future, to enable radiologists to cope with their stresses and improve health.

In the recent e-learning environment, avatars are often used to help learners get familiar with the contents, which is ultimately to motivate them to study more. Therefore, it is important to investigate whether avatars have actually the desirable effect on users of e-learning materials. Surprisingly, however, no extensive study has been conducted on this crucial issue Accordingly, main objectives this study are summarized as follows. First, we need to gain better understanding of how much learners' trust towards avatars (termed as "avatar trust") is transferred to learners' trust towards e-learning contents (termed as "contents trust"). Second, we need to investigate how much learners' personal relationships with avatars as well as learning behaviors change depending on avatar types (attractive vs. professional) and contents complexity (easy vs. difficult). As described in the study objectives, in order for us to analyze empirical data more systematically, we classified avatar types into two: "attractive" and "professional;" the contents are categorized as either "easy" or "difficult." Therefore, it is essential for this study to build a prototype e-learning website on which our research purpose can be realized and tested effectively with proper avatar types and e-learning contents. For this purpose, we built a prototype e-learning website, in which avatars are invited from currently working avatar instructors used in real-world e-learning websites, and e-learning contents are adapted from real-world contents about Java programming topic, which have been proved to have shown high quality and reliability. Our research method includes questionnaire survey by inviting a number of valid respondents comprised of office workers who are believed to have high demands for the e-learning contents as well as those who have previous experience with avatar instructors. Respondents were given one of the four e-learning experiment conditions (2 avatar types x 2 contents types) on a random basis. Each experimental e-learning condition is framed to have the same quality but different avatar type and content complexity. Then the respondents are asked to fill out the survey form which has questions about avatar trust, contents trust, personal relationships with avatar, and learning behavior, among others. Regarding the constructs used in research model, we based them rigorously on previous studies. For example, we used six constructs such as behavior to give information (BGI), behavior to obtain information (BOI), need for inclusion wanted, need for control wanted, contents trust, and avatar trust. To measure them, 7-Likert scales were used in the questionnaire. E-learning performance was measured indirectly through two constructs such as BGI and BOI. Six constructs used in the research model were adopted and revised from the FIRO-B model suggested by Schutz. Empirical results are as follows: First, professional avatars are more effective for difficult contents, while attractive avatars were not as effective for easy contents. Second, our study results ascertained that avatar trust transfers to contents trust regardless of avatar types and contents complexity.

This study was carried out to investigate the general characteristics of public health nutritionists, the current status of nutrition services operation, the recognition about nutrition services of public health center related man power, the job satisfaction and self-assessment and the need for a retraining course of public health nutritionists. The subjects were 58 public health nutritionists who responded to the questionnaire distributed at the annual retraining program in 1998. The results of this study are summarized as follows. 1) 46.5% of the nutritionists were 26-30 years old, 62.1% were 4 year university graduates 74.1% were food and nutrition majors and 51.7% were daily workers. 2) Among the public health center-related manpower, the recognition about nutrition services was the highest for the manager of family health section, followed by the head of public health centers, and then the general nurse in public health centers. 3) The ranking of the reasons for job satisfaction of the public health nutritionists was, relationship with colleagues(3.84), inhabitants response after nutrition counselling(3.53), specialized value realization/conviction about duty(3.35), contents of the work(3.10), value achievement(3.08), self achievement/development(3.00), self discretion(2.92), participation in policy decisions(2.90), work load(2.75), chance of retraining and acquisition of new information(2.73), working environment(2.69), supervisio $n^port by superiors(2.67), salary(2.38), supply of necessary education material, technique(2.37), and budget security(2.22). 4) The satisfaction of the inhabitant's responses after nutrition counseling was the highest among the 4 year university graduates(p<0.05), the satisfaction of the specialized value realization/conviction about duty was the highest among the nutritionists 26-30 years old(p<0.05). Food and nutrition majors(p<0.05) and those having worked less than 3-5years at public health centers also showed much satisfaction(p<0.05). Satisfaction with the salary was the lowest among the food and nutrition majors(p<0.01) and daily workers(p<0.001). The satisfaction with the participation in policy decisions was the lowest among the daily workers(p<0.01). 5) The ranking for the level of self-assessment were, nutrition and dietetic practice(2.92), communication(2.80), management(2.77), public health science and practice(2.66)(p<0.01). The general characteristics such as the level of education, major, employment condition, current public health center's tenure, and charge experience of the nutrition guidance work were not significantly related to self-assessment except the management part(p<0.05). The higher the satisfaction of specialized value realization/conviction about the duty, the better the total score on the self-assessment(p<0.05)..

This study set out to analyze the perceptions of investigative police officers and division police officers regarding Police Investigation Specialization, which had been in effect for four years, identify the problems, and search for alternative policies. The results led to the following alternative policies; first, the communication among the members should be facilitated by trading the jobs between investigative policemen and division members in certain percentage regularly, integrating job education and special work, and developing diverse support programs for detective activities to provide them with opportunities to experience and understand investigation. The second suggestion concerns the investigation members' morale. There should be a range of measures to boost their moral such as allocating separate budget and personnel to support the investigation department and the treatment of major criminal and civil cases, giving each investigation team an office and investigation room to improve their working environment, readjusting the promotion ratio of Police Investigation Specialization to introduce a promotion system proper for each investigation's characteristics. The third suggestion is to secure job efficiency. It's required to reinforce the current short-term specialized education program to bring up practical and professional investigators, open the certification exam of professional investigators to all members so that every policeman can have their abilities recognized and approved as long as they have the demanded capabilities, and create a system of shedding off the members idle at work by reflecting low performance records when evaluating the members to decide who to dismiss from Police Investigation Specialization. And finally, it's important to divide duties rationally. The rationality of duties division can be guaranteed by setting the guidelines for direct handling for the team leader to help him devote himself to his duties, defining objective criteria of measuring investigation workload, and creating devoted systems and teams for simple and small accidents so that experienced investigators can deal with high-profile cases.
