The purpose of this study is to develop and evaluate the scale for university students' health behaviors. This research is based on Roger's(1975) Protection Motivation Theory and Weinstein(1988)'s Precaution Adoption Process Model as theoretical frameworks. The contents of the scale were first abstracted from personal depth interviews of qualitative study on university students' health behavior experiences and review of its related literature. The initial items consisted of 76 behavior questions and 34 perception questions. After conducting the preliminary test, 33 behavior questions and 24 perception questions were selected for the final test by revisions on the basis of the result of the content validity test and the item understanding test. The questionnaires for the final test were distributed to 400 students enrolled in three universities. The questionnaires collected from 373 participants were analyzed by the SPSS program. From the examination of construct validity, item correlation, and factor relation turned out to be relevant. Five factors were determined from 27 items with a cumulative explained variance of 54.498 %. After examining reliability and validity of the collected dat, 27 items were finalized as the scale for university students' health behaviors.

The main objective of this study is to conduct subnational population projections of Korea based on a multiregional cohort-component method. This objective is accomplished by: (i) establishing a viable framework to implement the multiregional cohort-component method with reference to the Markov chain model and Rogers' multiregional population projection model; (ii) applying the established framework to subnational population projections of Korea, 2005~2030. The main results are twofold. First, the proposed method turns out to be highly valid in a methodological sense, which is seen from a high level of coincidence between the estimated and the observed. Second, the projection results turn out to be highly useful in the sense that interregional migration flow matrices are resulted for projection periods. The projected migration flows are expected to provide invaluable information for an understanding of future population change and for a formulation of policy alternatives. This study is strongly inspired by the multiregional perspective emphasizing the evolution of multiple regional populations interconnected by interregional migration flows rather than the overall national change.

A review of this literature and discussions reveal a development of ideas concerning the elements of nursing models. The elements of a nursing model are the nurses view of the human being, nursing's goal, and nursing activities. It has long been recognized that human beings, at one time or another, require nursing care. Varieties of literature were reviewed in regard to the human being as recipient of nursing care through the theory development in nursing. Florence Nightingale initiated the modern era of nursing and described more clearly man as the recipient of nursing care. She looked at man as responding to the laws of nature whether the person was healthy or sick. Henderson added to Nightingale's concept of man , the recipient of nursing care by emphasizing that man is a whole, complete, and independent being. Her view is further specified by her enumeration of the activities the human being must perform. Johnson has developed a very comprehensive view of man as the recipient of nursing care. Man is a behavioral system which has a tendency to achieve and maintain stability in patterns of functioning. Like Nightingale, Johnson sees that similar patterns occur in both health and illness. Johnson postulates that the whole behavioral system of the human is composed of eight sub-systems: affiliative, achievement, aggressive, dependency, eliminative, ingestive, restorative, sexual. Roger's main contribution to the development of nursing models was her emphasis upon unitary man. She pointed out that man is a unified whole, possessing his own integrity and manifesting characteristics that“are more than and different from the sum of his parts.”Rogers focuses on the life processes of the human and points out that these processes have the following characteristics. Wholeness, openness, unidirectionality, pattern and organization, sentence, and thought. According to Roy, man is a biopsychosocial being in constant interaction with a changing environment. To cope with this changing environment, man has certain innate and acquired mechanisms. Man's ability to respond positively or to adapt, depends upon the degree of the change taking place and the state of the person coping with the change. When she analyzes man as an adaptive organism she further describes man as being composed of four adaptive modes: physiological needs, self-concept, role function, and interdependence. Based on the literary review through the theory development in nursing, general approach by a unified nursing model to a view of the recipient of nursing care may be stated as follows: Man is a unified whole composed of subsystems with a flexible and normal line of defense; his internal regulating mechanisms help him to cope with a changing environment; he functions by the principles of homeodynamics.

In this paper, the implementation and embedding method of the existing air-filled waveguide-filters at millimeter-wave on general PCB substrate is introduced by systematically inserting the vias inside waveguide and mathematically manipulating the simple equations obtained ken the classical circular-post waveguide filter design. All the metal structures placed vertically such as side wall fur perfect ground plane and circular-post for signal control in the air-filled WR-22 waveguide are replaced with several types of via for constructing the bandpass-filter. Side wall and poles inside waveguide are realized by placing a series array of via and tuning the via diameter. The lengths of x, y, z axis are reduced in proportion to root square of employed substrate dielectric constant and especially the length of z axis can be more reduced due to the characteristics of the wave propagation. Because the mass production on PCB is possible without fabricating a large-scaled metal waveguide of WR-22 as input/output ports at millimeter-wave regime, the manufacturing cost is reduced considerably. Finally, when using multilayer process like LTCC for small-sized module, it is one of advantages to use only one layer f3r the filter fabrication. To evaluate the validity of this novel technique, order-3 Chebyshev BPF(Bandpass-Filter) centered at 40 GHz-band with a 2.5 ％ FBW (Fractional Bandwidth) were used. The employed substrate has relative dielectric constant of 2.2 and thickness of 10 mil of Rogers RT/Duroid 5880. Accroding to design and measurement results, a good performance of insertion loss of 2 ㏈ and return loss of -30 ㏈ is achieved at full input/output ports.

The purpose of this study is to analyze musical styles emerging in modern musical history from the perspective of integration and deconstruction, and to academically investigate the characteristics contained in each style. The style of musicals can be divided into periods of non-integrity, integration, deconstruction, and convergence. The rise of musical styles and the associated meanings can be studied from the perspective of modernism and postmodernism. In modernism, the energies of 'integration' and 'concentration' form the major trend while in early postmodernism, the powers of 'deconstruction' and 'dispersion' play the main role. Late postmodernism is a dialectic result of both trends in which the philosophy of 'convergence' and 'harmony' operates as the main theme. The principle of integration and deconstruction, which forms the base of musical creation, emerged after the development of the unstable style of non-integrity in the early days of musical. Later, with the advent of Rogers and Hammerstein II, the principle of integration was established for book musicals, emphasizing the linearity of drama, and the principle of deconstruction was born for concept musicals to contain new contents. The 'convergence' found in later musical works turn the theme from non-integrity to integration, and from deconstruction to integration again, which indicates that integration is embracing the concept of deconstruction again in a more advanced sense. Such convergent compromise that constantly influences each other and develops in a better direction can contribute to the development of musical styles.

The 1990s have seen the publication of many books devoted to Language and Ideology (cf. Joseph & Taylor 1990. for one of the early ones) even though the term 'ideology' itself has remained ill-defined (Woolard 1998). The focus of attention has usually been placed on the particular use of language and often for some kind of 'political' ends, not on linguistic or other scholarship which might have been driven by some sort of ideology, i.e., a bundle of assumptions which themselves were taken as given. At least since Edward Said's 1978 book Orientalism, it has been clear to everyone that scholars construct their conceptualization of things in line with their understanding of the cultural, social, and political world in which they live, and that this often unreflected 'pre-understanding' effects their view of cultures that are different from theirs and more often than not geographically and temporally distant from theirs. This recognition has had a sobering effect no doubt, and Said's book has long since become 'mainstream.' Much more disturbing to the scholarly profession has been the publication of Martin Bernal's Black Athena in 1987, since it went much further, going beyond accusations of colonialism and cultural bias, in suggesting that the Western representation of Classical Greece over the past two hundred years was false and that what had been accepted until now about occidental antiquity must now be seen derived from African-Asiatic cultures of the Near East, notably that of the Ancient Egyptians, and that no other than Socrates should be seen as black man. While we may understand the intellectual climate in the United States that led academics to present 'myth as history' (Lefkowitz 1996), it is obvious that lines of regular scholarly principles of investigation have been crossed (cf Lefkowitz & Rogers 1996). The present paper investigates what may be seen as the ideological underpinnings of such work. After reviewing some recent scholarship in the area of linguistic historiography that have shown that academic work has never been 'value-neutral' (as may have been assumed or has been claimed by some practitioners), it is argued that in effect one must be aware of what Clemens Knobloch has recently termed Resonanzbedarf, i.e., the desire, whether conscious or not, of scholars-and probably scientists, too-to have their work recognized by the educated public and that, in so doing, their discourses tend to pick up on contemporary popular notions. These efforts may be harmless if everyone was to recognize these allusions and adoption of certain lexical. items(buzz words) as props or what Germans call Versatzstiicke, but history tells us that this has not always been the case. Still, as Hutton (1999) has shown, not all scholarship during the Third Reich for example can simply be dismissed as worthless because it was conducted in under a prevailing political ideology. Indeed, in seemingly innocent times, linguists can be shown to frame their argument in a way that makes them appear so utterly superior to their predecessors (cf. Lawson 2001). Upon closer inspection, those discourses turn out to be much like those of scholars in nationalistic environments that have tended to select their 'facts' to prove a particular hypothesis (cf., e.g., Koerner 2001). The article argues for scholars to take a more active role in exploding myths, scientifically unfounded claims, and ideologically driven distortions, especially those that are socially and politically harmful.

When recognition of the Ghi(氣) which exist in all things, is changed on the aspects of the science of nursing, the view of health and nursing will be more efficient and can be developed as the proper concept for Korean culture. I think it is nessary to confirm which philosophical basis of the will be applicable to nursing and how to it has to be developed. Therefore I can for the research of the Ghi phenomena to attain the Thoughts of philosophy that is appropriate to expound those phenomena. And I attempt to induct "the fusion of horizons" to unify the view of the I world between Korea and the West. The Ghi is very energetic and omnipresent among the universe, Nature, and the human being. So it can organize all the primary elements of mental and I physical function of human as like life, mind, breath, feeling, energy, etc. A general concept of the Ghi is described as follows ; (1) The Ghi is the origin and essence to organize the universe, Nature, and the human being. (2) It is the perpetually movable thing. (3) And there are continuous transmission between the Ghi of the universe and the human through 'body, mind, and soul. For review on the philosophic basis of the Ghi, I studied out the identity of the doctrine of Li and Ch'i(理氣論) in the field of philosophy of Korea and the West. In Korea, the concept of the Vigor is based on Ch'i monolism(기일원론) and Li Ch'i dualism (이기이원론) of Yul-gok Lee's, Toi-kye Lee's, Hwa-dam's, and/or Hekang's. These are indispensable for the view of the world of Korea as Metaphysical ideology, Concrete science, Materialism, Ontology, and Epistemology. From the viewpoint of the philosophy of the West, the doctrine of Li and Ch'i(이기론) of Korea is identical with the doctrine of Li and Ch'i(이기론) of Joo-ja, Idea of Plato, Metaphysics of Aristotle, World Spirit(Weltgeist) of Hegel, and Existentialism of Heidegger. In the nursing theory of the West, some of them referred to the Ghi as like Energy field theory of Rogers and Energy exchange of Neuman. Though there are different in terminology, "energy" and the "Ghi" are induced comparable therapeutic action between the human and the environments. With the nursing theory of Korea, I have made an attempt to compare the Ghi with metaparadigm of nursing-the human being, the environment, the health, and the nursing. For the most part, the alternative therapy is resonable to the frame of the nursing theory of Korea. It is easy to apply alternative therapy on the every spot of nursing. So this therapy could be a kind of forms as nursing therapy in the nursing centers where take the duties of supporting in local societies. In result, independent nursing intervention will be activated by the nurse who puts up with the major parts. It is available to apply this therapy to palliation of pain, insomnia of infant, Sanhujori (산후조리), pain of menstruation, arthritis. And the alternative therapy makes it possible to propose the nursing model which represent originality, tradition, and history of the nursing of Korea. Additionally, in the field of the nursing, it is indispensable to choose a suitable methodology which is considered whether it is matched with a theory of philosophy in the boundary and object of the research. Because there are many way to get the knowledge of nursing related to the Ghi. In the science of nursing, context of sociocultural background and frame are required to understand the person who need to take care of (nursing client). But the value systems of the West and the East are distinctive each other as well as the behavior of health persuance. Therefore it is the basic research data of great worth to review philosophical the Ghi phenomena which is well known to Korean.

Two cases of canine intervertebral disc disease (IVDD) were treated twice a week with injection-acupuncture (injection-AP) using 0.1 ml/acupoint. In case 1, a paralysed dog with cervical intervertebral disc disease (C3-C4), was submitted to injection-AP with dexamethasone (1 mg/ml) at session 1-2 and thiamine (25 mg/ml) at session 3-5. Injected acupoints included GV-16, GB-20, BL-10, LU-7, LI-4 and SI-6. The acupoints GV-6, GV-20 and SP-6 were added at session 2-5. Trigger point (TP) therapy with 0.2 ml of 2% lidocaine was used in session 3-5 at TP in the infraspinatus and triceps muscles. Treatment was stopped when paralysis disappeared after 5 injection-AP treatments; there were no recurrent symptoms in the follow-up period of 5 months. In case 2, an ataxic dog with lumbar IVDD (L1-L2), was submitted to injection-AP with dexamethasone at session 1 and 2 and thiamine at session 3-4. Injected acupoints included GV-6 as the main point, ST-36, GB-30, ST-40, GB-34, ST-41 and BL-40. TP therapy with 0.2 ml of 2% lidocaine was used at TP in the ileocostorum lumborum and quadriceps muscles. Treatment was stopped when ataxia disappeared after 4 treatments; there were no recurrent symptoms In the fallow-up period of 5 months. Injection-AP using dexamethasone and thiamine, combined with TP therapy using lidocaine, effectively alleviate the symptoms of canine cervical and lumbar IVDD.

Vegetation development in rivers is one of the important issues not only in academic fields such as geomorphology, ecology, hydraulics, etc., but also in river management practices. The problem of river vegetation is directly connected to the harmony of conflicting values of flood management and ecosystem conservation. In Korea, since the 2000s, the issue of river vegetation and land formation has been continuously raised under various conditions, such as the regulating rivers downstream of the dams, the small eutrophicated tributary rivers, and the floodplain sites for the four major river projects. In this background, this study proposes a method for classifying the distribution of vegetation in rivers based on remote sensing data, and presents the results of applying this to the Naeseong Stream. The Naeseong Stream is a representative example of the river landscape that has changed due to vegetation development from 2014 to the latest. The remote sensing data used in the study are images of Sentinel 1 and 2 satellites, which is operated by the European Aerospace Administration (ESA), and provided by Google Earth Engine. For the ground truth, manually classified dataset on the surface of the Naeseong Stream in 2016 were used, where the area is divided into eight types including water, sand and herbaceous and woody vegetation. The classification method used a random forest classification technique, one of the machine learning algorithms. 1,000 samples were extracted from 10 pre-selected polygon regions, each half of them were used as training and verification data. The accuracy based on the verification data was found to be 82~85%. The model established through training was also applied to images from 2016 to 2020, and the process of changes in vegetation zones according to the year was presented. The technical limitations and improvement measures of this paper were considered. By providing quantitative information of the vegetation distribution, this technique is expected to be useful in practical management of vegetation such as thinning and rejuvenation of river vegetation as well as technical fields such as flood level calculation and flow-vegetation coupled modeling in rivers.

Services using artificial intelligence have begun to emerge in daily life. Artificial intelligence is applied to products in consumer electronics and communications such as artificial intelligence refrigerators and speakers. In the financial sector, using Kensho's artificial intelligence technology, the process of the stock trading system in Goldman Sachs was improved. For example, two stock traders could handle the work of 600 stock traders and the analytical work for 15 people for 4weeks could be processed in 5 minutes. Especially, big data analysis through machine learning among artificial intelligence fields is actively applied throughout the financial industry. The stock market analysis and investment modeling through machine learning theory are also actively studied. The limits of linearity problem existing in financial time series studies are overcome by using machine learning theory such as artificial intelligence prediction model. The study of quantitative financial data based on the past stock market-related numerical data is widely performed using artificial intelligence to forecast future movements of stock price or indices. Various other studies have been conducted to predict the future direction of the market or the stock price of companies by learning based on a large amount of text data such as various news and comments related to the stock market. Investing on commodity asset, one of alternative assets, is usually used for enhancing the stability and safety of traditional stock and bond asset portfolio. There are relatively few researches on the investment model about commodity asset than mainstream assets like equity and bond. Recently machine learning techniques are widely applied on financial world, especially on stock and bond investment model and it makes better trading model on this field and makes the change on the whole financial area. In this study we made investment model using Support Vector Machine among the machine learning models. There are some researches on commodity asset focusing on the price prediction of the specific commodity but it is hard to find the researches about investment model of commodity as asset allocation using machine learning model. We propose a method of forecasting four major commodity indices, portfolio made of commodity futures, and individual commodity futures, using SVM model. The four major commodity indices are Goldman Sachs Commodity Index(GSCI), Dow Jones UBS Commodity Index(DJUI), Thomson Reuters/Core Commodity CRB Index(TRCI), and Rogers International Commodity Index(RI). We selected each two individual futures among three sectors as energy, agriculture, and metals that are actively traded on CME market and have enough liquidity. They are Crude Oil, Natural Gas, Corn, Wheat, Gold and Silver Futures. We made the equally weighted portfolio with six commodity futures for comparing with other commodity indices. We set the 19 macroeconomic indicators including stock market indices, exports & imports trade data, labor market data, and composite leading indicators as the input data of the model because commodity asset is very closely related with the macroeconomic activities. They are 14 US economic indicators, two Chinese economic indicators and two Korean economic indicators. Data period is from January 1990 to May 2017. We set the former 195 monthly data as training data and the latter 125 monthly data as test data. In this study, we verified that the performance of the equally weighted commodity futures portfolio rebalanced by the SVM model is better than that of other commodity indices. The prediction accuracy of the model for the commodity indices does not exceed 50% regardless of the SVM kernel function. On the other hand, the prediction accuracy of equally weighted commodity futures portfolio is 53%. The prediction accuracy of the individual commodity futures model is better than that of commodity indices model especially in agriculture and metal sectors. The individual commodity futures portfolio excluding the energy sector has outperformed the three sectors covered by individual commodity futures portfolio. In order to verify the validity of the model, it is judged that the analysis results should be similar despite variations in data period. So we also examined the odd numbered year data as training data and the even numbered year data as test data and we confirmed that the analysis results are similar. As a result, when we allocate commodity assets to traditional portfolio composed of stock, bond, and cash, we can get more effective investment performance not by investing commodity indices but by investing commodity futures. Especially we can get better performance by rebalanced commodity futures portfolio designed by SVM model.
