Constructivism gave many implications to science education but at the same time it has brought confusion about its implication to the field of science education. Hermeneutics has possibilities of being able to reduce confusion as well as opening a new horizon. Hermeneutics seeks the meaning of 'real understanding' through the concepts of horizon, hermeneutical circle, and fusion of horizons. Both hermeneutics and constructivism have positive attitude to students' pre-understanding and accept contextualization of knowledge. Thus, they both can criticize traditional teaching method and propose an alternative. Moreover, hermeneutics approaches human understanding holistically with the concept of horizon, and pays attention to the circularity of the process of human understanding. As a result, hermeneutics can open a new horizon and give new discourse to science education and contribute to the development of research and practice of science education.

Examined how it varied the knowledge network of the country along with R&D changes in planning policy for the research and development of government. Therefore, in this study, chronological Analysis analyzed separately the network between each entity of participate in the industry fusion source technology development business of industry trade and Energy. Planning policy of industrial fusion source technology development business, to change the starting point before and after 2012, before 2012 from selected planning issues at the center "planning committee" and in 2012 'PD' changes to a system for planning issues around. First of all, an attempt to analyze the R&D network based on the "planning committee" current situation of 2009~2011, from 2012 to analyze the variation of the R&D network with the introduction of the 'PD' system after it was analyzed by dividing the time in the current state of up to 2013. The results of the analysis, since the PD system was introduced, such as self-relationship (the form of planning user to run directly challenges the person was planning to challenge participants)is greatly improved, I was able to grasp the effect became clear. The more the self-relation, and the budding scholars considering that there is inequality of the planning, the introduction of the PD scheme, it can be seen to have resulted in a positive effect. These studies, quantitatively analyzed to improve the results to the effects associated with changes in the planning policy of the government, I think that there is a meaning in terms of presenting the future direction of R&D policy.

In early Josun(朝鮮) era, the scholars, genteels, and high officials in Josun dynasty paid attention to Sijo(時調) who hoped Josun society would share Confucian values. Sijo poems written by them are based upon Confucian ideology, giving an opportunity to its members to make sure their homogeneity and helping Josun dynasty sustain its regime. Gyongichega(景幾體歌) has, however, already failed to be an appropriate genre to do these functions. Nevertheless, in the late Josun dynasty when there were agitation in class hieracy, development of currency economics, maldistribution of wealth, and pursuit of enjoyment, obscene poems turned out. Consequently these songs contributed to encroaching and eventually destroying the Josun dynasty. The question that who are in charge of creating and enjoying Sasulsijo(辭說時調) cannot be answered by approaching it in the social class point of view. The range of the maker or the reader of Sasulsijo in the late Josun dynasty was much more extensive than that in the early times. Not only aristocracy or the middle society but even some of the lower class may have made and enjoyed those songs. In the meantime, it is singer-songwriters whom Park, Hyogwan blamed for their profiteering abuse of obscenity that is supposed to have been mainly reponsible for the creation of those songs. Siga is a double-edged art in its essence--the good and the bad. The lewd songs were, in the early Josun, strictly controlled but in the late Josun dynasty, were thriving due to social changes. In this context, songs based on Confucian ideology as well as the ones focused on sexual love became decayed along with the collapse of the Josun dynasty. Even though, in the light of the history of Siga, those two types of Siga are underestimated in its artistic value, they have very special social historical meaning in doing positive and negative functions for existence and destroy of the Josun dynasty.

Background : Pulse-respiration ratio has been used for estimating subject's status in oriental medicine. Pulse and respiration is strongly associated with autonomic nerve system. But there is no research about correlation between pulse-respiration ratio and autonomic nerve system. Objectives : We performed this study to know correlation between pulse-respiration ratio and HRV(heart rate variability) that shows autonomic nerve system status well and to clarify clinical meaning of pulse-respiration ratio. Methods : After subject's 10 minutes rest, we measured subject's ECG, respiration pattern and HRV. In this research, subject's number is 95(Male 50/Female 45). We calculated pulse-respiration ratio from ECG and respiration pattern. Then, we analyzed correlation between pulse-respiration ratio and HRV parameters in all subjects, 2 group divided by Wan-Maek(P-R ratio 4.28). We tried to compare HRV parameters among Wan-Maek, Sak-Maek and Ji-Maek group. Correlation analysis between pulse-respiration Ratio and Pulse rate, respiration rate is performed. Finally correlation analysis between Respiration and HRV parameters in all subjects, 2 group divided by Wan-Maek(4.28) is studied. Results : 1. Mean pulse-respiration is 4.10${\pm}$0.67, Mean pulse rate is 68.06${\pm}$7.82bpm, Mean respiration rate is 16.81${\pm}$2.72 times per minute in all subjects. 2. Correlation analysis between pulse-respiration ratio and HRV parameters of high pulse-respiration ratio group is not significant. But, in low pulse-respiration ratio group, HFnorm(correlation coefficient 0.306, p= 0.018), lnHF (0.308, p=0.002) is significantly correlated with pulse-respiration ratio. 3. Comparison of HRV parameters among Wan-Maek, Sak-Maek and Ji-Maek Group is not significant. 4. Pulse-respiration ratio is more affected by respiration rate(correlation coefficient-0.17, p=0.000) than pulse rate (correlation coefficient 0.396, p=0.000). 5. Correlation analysis between respiration rate and HRV parameters of high pulse-respiration ratio group is not significant. But, in low pulse-respiration ratio group, HFnorm (correlation coefficient -0.327, p=0.011), LF/HF(0.346, p=0.007), lnHF (-0.355, p=0.006) are significantly correlated with respiration rate. Conclusion : Pulse-respiration ratio and parasympathetic index has positive correlation. The closer Wan-Maek, The higher parasympathetic index in low pulse-respiration ratio group. Respiration rate is more related with pulse-respiration ratio than pulse rate. Respiration is negatively correlated with autonomic parameters. And the slower respiration, the higher parasympathetic index in low pulse-respiration ratio group.

There are normal inhabitants doing medically useful functions in the body. There are many kinds of bacteria performing specific functions in the oral cavity. Two strains of lactic add bacteria were isolated from normal inhabitants of children's oral cavity, which inhibited the production of volatile sulfur compounds by anaerobic bacteria. The authors identified the isolates by 16S rDNA partial sequencing. 1. Two isolates were Gram-positive bacilli and produced hydrogen peroxide. 2. When Streptococcus mutans was cultured in the media, the mean weight of formed artificial plaque on the orthodontic wires was $124.4{\pm}30.4$ mg, whereas being reduced to $5.2{\pm}2.0$ mg and $10.6{\pm}6.6$ mg in the media cultured with Streptococcus mutans and each isolate, respectively(p<0.05). 3. The number of viable cells of Streptococcus mutans was $3.4{\times}10^9$ per ml in the cultured solution, whereas those of Streptococcus mutans in the combined culture with each of isolates were $4.6{\times}10^8$ and $2.4{\times}10^8$ per ml. 4. The optical density was 1.286 in the supernatant of Fusoacterium nucleatum after vortexing for 30 minutes, whereas in the supernatant of combined Fusoacterium nucleatum and each isolate, they were reduced to 0.628 and 00497, which the percentages of coaggregation between them were 2904% and 57.8%, respectively. 5. The optical density of Fusoacterium nucleatum precipitate was 1.794 in the culture media containing cysteine and $FeSO_4$ being reduced to 1.144 and 0.915 in the coaggregated precipitates of Fusoacterium nucleatum and each isolate. 6. The similarity values of 16S rDNA sequence between each of isolates and Lactobacillus salivarius subsp. salicinius were 99.60% and 99.73%, respectively, meaning that isolates were Lactobacillus salivarius subsp. salicinius. These results indicated that two strains isolated from children's saliva, which inhibited the formation of plaque and the production of volatile sulfur compounds, were identified as Lactobacillus salivarius subsp. salicinius.

In the situation that crime is diversified qualitatively and quantitatively, the mutual cooperation system between police and private security is very important to cope with the change of policing environment properly. The primary purpose of this study is to suggest the method to improve the policing service quality of police and advance sound security industry by analyzing the case of close mutual cooperation system between police and private security of USA, which can be called the best country in the field of private security. When considering the cases of USA synthetically, we can know that as the most basic characteristic, the discussion over actual cooperation method is performed on the basis of positive recognition over mutual existence of police or private security. It means that the mutual relationship is based on the basic recognition over partner relationship to meet citizen's desire for safety. While reviewing the cases of USA, Korea shall refer to the fact that social safety activities of advanced countries display effects because of many factors such as various mutual cooperation programs between police and private security, efforts of local government, high quality of private security, reliance of citizen and general understanding of police, private security and citizen to solve crime problem. As shown in the review of USA cases, when considering the fact that the mutual cooperation between police and private security is performed in the level of autonomous police, Korea shall perform autonomous police system to provide better policing service, which is close to citizen.

Purpose: We examined the effects of a well-dying program on nursing students in terms of death preparation, death recognition and perception of well-dying perception. Methods: The design of this study was quasi-experimental and non-synchronized with a non-equivalent control group. The study was conducted with nursing students: 32 in the experimental group and 36 in the control group. The well-dying program was consisted of five sessions: introduction, thinking about meaning of death, organizing things to do before dying, looking back on my life, and leaving a trail of my life. Descriptive analysis, t-test, ${\chi}^2$ test and ANCOVA were used with SPSS 18.0 program to analyze the data. Results: After attending the program, a difference was observed in death preparation of the experimental group (t=2.61, P=0.014). The death recognition (F=154.15, P<0.001) score of the experimental group was significantly higher than the control group. There was no significant difference between the groups in perception of well-dying (F=0.11, P=0.747). Conclusions: The well-dying program helped nursing students build positive death recognition. Therefore, this study is expected to contribute to development of a death education program for nursing students.

In this study the interpretive perspective means a point of view on educational curriculum in which in order to reach the understanding of the meaning of the behaviors and beliefs of human beings, and the historical and cultural products, the process of discussing on the basis of historical and cultural knowledge is very important. The developed curriculum means the one that consists of the goal of the curriculum, the contents of the curriculum, lesson plans, and the instruction-learning materials. This study has been carried out in four steps: conceptualization, development, application and evaluation. This study has tried to propose some changes in the contents of clothing life education on the basis of the interpretive perspective by firstly, assuming some core concepts that were related to clothing life education in Home Economics and secondly, organizing the contents of the clothing life culture area based upon historical and cultural materials. The results of the application of the developed curriculum came out positive. The strong points of the developed curriculum showed that for the students the curriculum was helpful in seeking answers to such questions as 'who I am' and 'what kind of being I am' through the perception of traditional culture and clothing life. In addition, the developed learning contents were recognized as new knowledge. It also showed that teaching contents with a focus on the interpretive perspective could play a role as reflection for the practice and for the arrival at the final perception. A weak point of the developed curriculum is that the Home Economics teachers themselves might find difficulty preparation for teaching this material because of their limited understanding and knowledge of the historical and cultural materials about clothing life.
