Among the employer-supported subscribers to the National Health Insurance Service, 6,797 people with mild disabilities with western ages of 20 and up and who received health checkups were investigated. Of these 6,797 people, 3,186 and 3,611 received health checkups in 2009 and 2013, respectively. Those people who were diagnosed with physical handicaps, brain lesions, visual impairment, hearing impairment, intellectual disabilities, mental disorders, kidney disorders or other disorders according to the classification standard for people with disabilities were classified into disability groups of the 3rd through 6th degrees. The purpose of this study was to examine the dangerous influence of obesity of people with mild disabilities on their hyperglycemia, hypertension and high cholesterol. The items measured in this study were abdominal obesity, body mass index, fasting glucose, total cholesterol, systolic blood pressure and diastolic blood pressure. To look for connections between the obesity level and at-risk groups for each disease, cross tabulation and multinomial logistic regression analyses were utilized. Higher levels of abdominal obesity and BMI were found among those who were male, were younger and had higher incomes. The risks of abdominal obesity and BMI were higher in the abnormal groups for each disease. In 2009, the obesity group whose BMI was higher had a 1.51-fold higher risk of hypertension than the normal group. The abdominal obesity group had a 1.59-fold higher risk of high cholesterol, a 1.26-fold higher risk of hypertension and a 1.54-fold higher risk of hyperglycemia than the normal group. In 2013, the obesity group whose BMI was higher had a 1.72-fold higher risk of high cholesterol and a 1.43-fold higher risk of hypertension than the normal group. Those with abdominal obesity had a 1.59-fold higher risk of hyperglycemia than the normal subjects. As the risk of obesity was higher in those with disabilities than in those without disabilities, the former should be encouraged to undergo health checkups on a regular basis, and the coverage of the health checkups should be extended to keep track of their illness. In addition, appropriate education and concern are both required to prevent obesity.

Consumers demand that corporates fulfill their social responsibility by exerting influence over not only economical values but also social values in markets. Given such a social mood, most corporates are actively engaging in Corporate Social Responsibility(CSR) activities, and marketing scholars continue to study the effects of such CSR activities. Numerous such studies examined the relationship between CSR activity and brand equity. Moreover, virtually, a majority of these studies focused on consumer responses to CSR activity from an individual brand perspective. In a situation in which brand management must consider the spillover effects of brands, firms holding various brands should consider these spillover effects when they establish CSR activity strategies. Therefore, we examine the effects of CSR activity using a comprehensive approach that considers the hierarchy of brands. Additionally, we develop a new perspective on fit that has been used as a major influence on the effects of CSR activity. We argue that the mixed results of the impact of fit regarding the effect of CSR activities is attributed to the influence of connections among brands based on the hierarchy of brands. We then examine the effect of two types of CSR activity strategies that reflect the relativity of fit. The results reveal that there was no difference in impact of the two strategies based on unique roles and traits of corporate brand and effects of low fit. Also, we found that the corporate brand focused strategy creates a greater change in consumers' attitudes than does an individual brand focused strategy in the case of a particular brand. This finding is meaningful because it indicates that a hierarchy of brands may relatively reduce the impact of the role of fit, unlike general arguments from previous related research. Second, the spillover effects from the CSR activities of individual sub-brands belonging to the same corporate brand were confirmed. Therefore, we clearly verified the role of the hierarchy of brands. Although both strategies cause changes in consumer attitude toward brands engaged in CSR activity, overall, a corporate brand focused strategy turned out to be more effective than an individual brand focused strategy because of the spillover effects of brands. Third, this study verified the effect of a corporate brand focused strategy through a moderating effect analysis of the degree of association between individual brands and corporate brand. Given these results, we identified a moderating role in the degree of association and the changes in consumer attitudes toward both main brands engaged in CSR activities and other different individual brands, which were caused by the spillover effects of brands. Finally, this study addresses implications and limitations.

The purpose of this study is to construct ecological pond using LID technique in order to create naturally comfortable community space in urban idle space. The specification of the ecological pond is $110m^2$ of surface area, $0.45{\pm}0.02m$ of average depth, and bed material is composed of gravel (diameter ${\leq}60mm$), sand (diameter ${\leq}2mm$) and bentonite. Rainfall and water depth monitoring were conducted to determine the annual characteristics of inflow of the water for the ecological pond, result of total rainfall was 1,287 mm and showed a seasonal imbalance that accounted for 71.3% (918 mm) during July to August, but the annual mean water depth was kept constant at $0.45{\pm}0.02m$ due to the secondary water source. Annual trends of basic water quality showed a significant changes according to the season, such as water temperature ($5.2{\sim}28.8^{\circ}C$), DO (5.0 ~ 13.8 mg/L), EC ($113{\sim}265{\mu}S/cm$). BOD, COD, TN, and TP in physicochemical water quality tended to increase after October, but the ion parameters such as $NH_3$ and $PO_4{^{3-}}$ were generally low. Phytoplankton indicators Chl-a and BGA (blue green algae) showed a sharp increase from July to August, and green algae (Selenastrum bibraianum, Pediastrum boryanum etc.) and filamentous blue green algae (Phormidium sp.) emerged as a dominant species. The ion parameters ($F^-$, $Na^+$, $K^+$, $Mg^{2+}$, $Ca^{2+}$) were strongly correlated with the $Cl^-$ as a conservative substance (R=0.70~0.97, p<0.05). Water quality was influenced by the ambient environment such as seasonal changes or rainfall, and it was closely related to fluctuation of the inflow of the water. In the future, it is necessary to consider ecological connections by referring to the characteristics surveyed in this study in order to effectively manage the water quality and biodiversity of the ecological pond in idle space.

This paper started with my effort to find connections between Empty Hands, which was put on the stage at the Mime House in Chuncheon, Gangwon Province, and Jindo Ssitgimgut. The mimist Yu Jin-gyu(58) adopted so many elements from Jindo Ssitgimgut for his performance that I felt that it was the pantomime version of Jindo Ssitgimgut. Of course, the pantomime took the form of gut based on shamanism in terms of story. Watching the pantomime, I once again saw the possibility of developing Korea's cultural archetypes into cultural contents. Helen Lannaghan, the art director of London International Mime Festival of 2005, saw his performance at the conference of Chuncheon International Mime Festival and invited it to the London International Mime Festival praising that it's full of Korean elements, minimalist, and modern at the same time. In fact, Empty Hands, which boasts great harmony among the Korean objet, Oriental thoughts, Samulnori, and Western contemporary mime, was invited to many foreign festivals including the Mimos International Mime Festival in 2000, Polish International Mime Festival in 2001, Mongol's International Mime Festival in 2002, and Belgium's International Mime Festival in 2003. In addition, it's recognized for its artistic values and had a chance to shine in another international setting at the London International Mime Festival whose reputations have been worldwide. All those achievements are the result of Yu's constant effort to reflect Korean elements through his movements. What I saw in his pantomime was the possibility that plays based on Korea's cultural archetypes such as Jindo Ssitgimgut could play an important role as a global content of performance culture. Pursuing the possibility further, I analyzed the factors that brought the worldwide recognition to Empty Hands and searched for the ways to create solid storytelling with Jindo Ssitgimgut and make a huge hit on the international stage. It should be noted once more that the pantomime Empty Hands launched Korea's unique performance culture to the world stage by making great use of the traditional Korean cultural contents.

This research focuses on 'dramaturgical' performance among all the acts of a director who constructs an artistic structure. This is, specifically, the dramaturgical acts that a director comes to perform in the process of dramatizing a novel. This paper aims to suggest a new kind of approach for productive interaction between drama theory and practice, not only by documenting the process of creation but also by moulding theoretical basis on acts of a director. As you all know, creative acts in practice so far have rarely been considered as subject and purpose of academic study. Even some lucky plays and directors had to settle for fragmentary review. That's mainly because Korean theatrical circles confine the way of recording the whole process of drama in practice only to a piecemeal review of performance. As a result, there have been very few cases of observing comtemporary plays under the historical background of drama. In this regard, this paper desires to raise a question, 'is productive interaction between drama theory and creative practice possible?' and to find the answer. If what is described in this paper can have worth beyond a mere record of creative acts, it may establish theoretical grounds on interpreting the play stage of this era by reading, in the contexts of drama history, a director's dramaturgical performing acts to dramatize a novel. The researcher of this paper, as a director of a theater troupe like a human and artistic community, adapted "Crime and Punishment" by Dostoevsky into four plays. They are , , , , and completed in 2009, 2011, 2012, and 2014, respectively as an independent theatric work having no connections to each other in story. Not only because the four plays share the same novel as its origin but also because an identical system is applied to dramatization of the novel, it gives an opportunity to focus on and perceive the role of the director. During the process of dramatiztion, the director, the researcher of this paper, carried all the duties, such as selecting a text, approaching the text theoretically and academically, adapting it for drama, picking out appropriate episodes. This paper defines all these acts as dramaturgical performing acts. In this sense, this paper can also be seen as a documentary of 'acts' performed during the process of dramatization.

Stock market investors are generally split into foreign investors, institutional investors, and individual investors. Compared to individual investor groups, professional investor groups such as foreign investors have an advantage in information and financial power and, as a result, foreign investors are known to show good investment performance among market participants. The purpose of this study is to propose an investment strategy that combines investor-specific transaction information and machine learning, and to analyze the portfolio investment performance of the proposed model using actual stock price and investor-specific transaction data. The Korea Exchange offers daily information on the volume of purchase and sale of each investor to securities firms. We developed a data collection program in C# programming language using an API provided by Daishin Securities Cybosplus, and collected 151 out of 200 KOSPI stocks with daily opening price, closing price and investor-specific net purchase data from January 2, 2007 to July 31, 2017. The self-organizing map model is an artificial neural network that performs clustering by unsupervised learning and has been introduced by Teuvo Kohonen since 1984. We implement competition among intra-surface artificial neurons, and all connections are non-recursive artificial neural networks that go from bottom to top. It can also be expanded to multiple layers, although many fault layers are commonly used. Linear functions are used by active functions of artificial nerve cells, and learning rules use Instar rules as well as general competitive learning. The core of the backpropagation model is the model that performs classification by supervised learning as an artificial neural network. We grouped and transformed investor-specific transaction volume data to learn backpropagation models through the self-organizing map model of artificial neural networks. As a result of the estimation of verification data through training, the portfolios were rebalanced monthly. For performance analysis, a passive portfolio was designated and the KOSPI 200 and KOSPI index returns for proxies on market returns were also obtained. Performance analysis was conducted using the equally-weighted portfolio return, compound interest rate, annual return, Maximum Draw Down, standard deviation, and Sharpe Ratio. Buy and hold returns of the top 10 market capitalization stocks are designated as a benchmark. Buy and hold strategy is the best strategy under the efficient market hypothesis. The prediction rate of learning data using backpropagation model was significantly high at 96.61%, while the prediction rate of verification data was also relatively high in the results of the 57.1% verification data. The performance evaluation of self-organizing map grouping can be determined as a result of a backpropagation model. This is because if the grouping results of the self-organizing map model had been poor, the learning results of the backpropagation model would have been poor. In this way, the performance assessment of machine learning is judged to be better learned than previous studies. Our portfolio doubled the return on the benchmark and performed better than the market returns on the KOSPI and KOSPI 200 indexes. In contrast to the benchmark, the MDD and standard deviation for portfolio risk indicators also showed better results. The Sharpe Ratio performed higher than benchmarks and stock market indexes. Through this, we presented the direction of portfolio composition program using machine learning and investor-specific transaction information and showed that it can be used to develop programs for real stock investment. The return is the result of monthly portfolio composition and asset rebalancing to the same proportion. Better outcomes are predicted when forming a monthly portfolio if the system is enforced by rebalancing the suggested stocks continuously without selling and re-buying it. Therefore, real transactions appear to be relevant.

The aim of this research is to discover the value of peace conveyed by Haewon Sangsaeng, the Resolution of Grievances for Mutual Beneficence, as espoused by Holy Teacher Kang Jeungsan (姜甑山, 1871~1909) and to evaluate its modern significance. To the faithful, Jeungsan is seen as the Supreme God who descended into the world in the Late Joseon Dynasty in the year 1871. Until the time of His passing away into Heaven in 1909, He vastly saved the world and fulfilled the hopes of humankind by carrying out the fundamentally innovative Reordering Works of Heaven and Earth (1901~1909) in the Three Realms of Heaven, Earth, and Humanity. He has thereby been appraised as a great religious figure within religious and academic circles. Jeungsan's ideological contributions can be summarized into two main points. One is the concept of 'the Great Opening and the Later World,' which foreshadowed the liquidation of the old system of order and the arrival of a new world. The other contribution is the concept of 'the Resolution of Grievances for Mutual Beneficence,' a fundamental principle meant to achieve human salvation and world peace. In this context, 'the Great Opening' is precisely a 'positivistic religious expression of peace,' and 'the Resolution of Grievances for Mutual Beneficence' is the principle by which 'peace can be achieved in the world for all humankind.' In particular, the Resolution of Grievances for Mutual Beneficence is a tenet within the doctrine of Daesoon Jinrihoe, and it is the main concept that forms the basis of Daesoon Thought. It can be said to be the core current that flows through Jeungsan's Reordering Works of Heaven and Earth. Nowadays, the Resolution of Grievances for Mutual Beneficence is being discussed and cited in various ways in academic fields as well as in discourse on coexistence, mutual beneficence, and peace. The Resolution of Grievances for Mutual Beneficence is specifically based on observations of the structure of conflicts as observed throughout world history via global conflicts, regional conflicts, cultural conflicts, ideological conflicts, class conflicts, generational conflicts, racial conflicts, religious conflicts, and other such conflicts. That is why the Resolution of Grievances for Mutual Beneficence is discussed in depth within academic settings wherein the nature of conflict-resolution is examined. Looking at the previous studies on this topic, those studies tended to focus on key concepts or concerns such as human beings, divine beings, the earthly paradise of the Later World, ideal societies, world peace, new principles of order, and lasting peace. In particular, the Resolution of Grievances for Mutual Beneficence has been presented as directly related to concepts such as love, coexistence, harmony, and peace for humankind and the world. Its significance has been applied to ethics, philosophy, order, and principles, and it has been understood as conveying values such as peace. Accordingly, this paper examines the ideological connections to the succession and establishment of Jeungsan's notion of the Resolution of Grievances for Mutual Beneficence based on previous research, but further examines the value of peace communicated via the principles and ideas that pervade current discourse on the Resolution of Grievances for Mutual Beneficence. I hope to thoroughly explore Haewon Sangsaeng in regards to its modern significance to the world and to humankind.

In order to increase timber self-sufficiency, Korea's 6th Basic Forest Plan aims to increase the density of forest roads to 12.8 m ha^-1 by 2037. However, due to rapid re-forestation, current management infrastructure is insufficient, with just 4.8 m ha^-1 of forest roads in 2017. This is partly due to time and cost limitations on the process of forest road feasibility evaluation, which considers factors such as topography and forest conditions. To solve this problem, we propose an eco-friendly and efficient forest road network planning method using a geographic information system (GIS), which can evaluate a potential road site remotely based on spatial information. To facilitate such planning, this study identifies forest road construction priorities that can be evaluated using spatial information, such as topography, forest type and forest disasters. A method of predicting the optimal route to connect a forest road with existing roads is also derived. Overlapping analysis was performed using GIS-MCE (which combines GIS with multi-criteria evaluation), targeting the areas of Cheongsong-gun and Buk-gu, Pohang-si, which have a low forest-road density. Each factor affecting the suitability of a proposed new forest road site was assigned a cost, creating a cost surface that facilitates prioritization for each forest type. The forest path's optimal route was then derived using least-cost path analysis. The results of this process were 30 forestry site recommendations in Cheongsong-gun and one in Buk-gu, Pohang-si; this would increase forest road density for the managed forest sites in Cheongsong-gun from 1.58 m ha^-1 to 2.55 m ha^-1. This evaluation method can contribute to the policy of increasing timber self-sufficiency by providing clear guidelines for selecting forest road construction sites and predicting optimal connections to the existing road network.

As for the matter of guardianship-benefit network which has been at the heart of the discussion of power elites and clan politics in Kazakhstan, it has been often maintained that it is basically formed by the framework of the regional and descent connection net called Zhuz or at least it has been heavily under Zhuz's influence. But it is pointed out that the controversy of Zhuz suffers from a lot of limitations in explaining the surface of power elites in the recent process of political changes and the rearrangement of power relations. Consequently, this paper tried to take a closer look at the matter focusing on the social backgrounds of elites from Junior zhuz, who have been estimated to be relatively pushed back in terms of the advancement into the central power. As a result, it was found that the backgrounds of clan and tribe origin within Zhuz couldn't have any foundation to be seen as a decisive element through which they could grow into power elites. The phenomenon of Kazakhstani elites is a legacy of concrete historic situations. The important consideration points for analyzing the emergence of elites which could be applied to a nomadic and traditional society can hardly be an invariable framework for analyzing modern elites since independence. Since 2000, Kazakhstan has experienced economic changes including privatization due to the absolute strengthening of presidential influence which turned into a foundation for a new authoritarian system, the rearrangement of the inner circle of power, and their decisions. These changes in situations have had profound effects on the character of power elites. The phenomenon that clandestine connections have shown their appearances as they have gotten intertwined with various factors, in particular, in the economic field which has been heavily under Junior zhuz makes us convinced that the elite organization in Kazakhstan has always been the product of political and economic changes. In reality, the behaviors of elites were the outcome continuously reflecting environmental situations surrounding them, and those situations lie in a complicated and multiple-layered connection net. Therefore, it is believed that having interests in elites' social backgrounds and maintaining many pieces of information on them will be able to be a more useful approach to analyzing the elite society in the future in that interests in their social backgrounds become an informant of various network formation nets which reflect real situations.

Most of the new religions derived from Jeungsan have claimed that Jeungsan's religious thought reproduced Dangun [檀君] Thought in its original form. However, Daesoon Jinrihoe is the only religious order out of the many new religions within the Jeungsan lineage, which has constantly kept its distance from Dangun Thought since 1909 during the earliest period of proto-Daesoon Jinrihoe. Even a mere trace of Dangun cannot be found in the subject of faith or the doctrinal system of Daesoon Jinrihoe. In this context, this study aims to examine possible connections between Daesoon Thought and Dangun Thought in order to determine why other Jeungsanist religions frequently exhibit Dangunist features. Specifically, a major part of this study will be devoted to comparing and analyzing the narrative structure of Daesoon Thought and Dangun Thought as well as their respective motifs. In fact, Jeungsan does not seem to have ever mentioned Dangun in his recorded teachings, therefore, after his passing into the Heaven, most of the religious orders including Daesoon Jinrihoe derived from him did not pay any attention to Dangun Thought for almost for 40 years. These orders did not originally perceive Dangun as an object of belief. After Korea's liberation, Dangun became widely accepted as a pivotal role among the Korean people. As Dangun-nationalism claimed to unify Koreans as one great Korean ethnic society, the religious orders of Jeungsan lineage also climbed aboard this creed and their faiths or doctrines were acculturated to reflect this change. The reason for this has been attributed to following modern trends to increase success in propagation. In the meantime, Daesoon Jinrihoe was the only order that did not accept Dangun-nationalism because it was not a teaching given by the order's founder. And the two systems of thought have more dissimilarity than parallelism in terms of philosophical ideology. These seem to be the main reasons why Daesoon Jinrihoe did not adopt Dangun into its doctrine or belief system.
