North Korea has conserved operas in a selective manner. The subject matters of operas recorded in the history of North Korea can be divided into classical tales, translated foreign works, Korean War and war against Japan. Operas that adapted folk classics of the 1950s are considered valuable materials to verify the changes of genres posterior to division of regime between North and South Korea. The officially confirmed works include "Kumgangsan Palseonnyeo (Gyeonwoo Jiknyeo)," "Chunhyangjeon." "Kongjwi Patjwi (Kotsin)," "Ondal," and "Geumnaneui Dal." These works had gone through recreation in terms of realistic situation setting, abolition of class difference, adjustment of social rank and punishment of evil while the base lies in the original folk classics. People emphasized in adapted folk operas are described as those who are hard-working souls without giving importance of difference of social rank, content with the currently living space, devoted to their parents and full of patriotic spirit, and members of community who participate in organized fights against unfair exploitation. This was the fruit of encouragement of work creation supporting union between labor and individual life, destruction of old things and fight promoting this destruction. Folk operas of South and North Korea posterior to Korean War have similarities in that both deal with a love story transcending social ranks and the concomitant conflicts and they focus on the audience who enjoy the operas. Nonetheless, they are different in that this love in North Korea became a tool of educating people wished by the regime, while it became an object of securing the audience by adding the tragic element to love in South Korea. North Korean operas of the initial stage are characterized by playwriting method emphasizing difficult life and compensation of common people, realistic stage expression, accentuation of melody and agreement between notes and lyrics. This was efforts designed to continuously lead senses concentrated from the theater to everyday life of people. In effect, this is in line with the playwriting method of revolutionary operas. Adapted folk operas were subject matters ideal for easily approaching the audience and leaving them good memories at the same time. To realize socialist realism, they went through an experiment of reviewing "people" through the classic folk operas. The possibility of continuation of a work was determined by thorough evaluation after carrying out an experiment in terms of subject matters, theme, music and operation plans from the moment of which the work was on the stage. The sign consisted in the possibility of visit of "Kim Il-sung" to appreciate the work and presentation of directionality. By proposing the clear directionality of which hard-working people who deny social status system can be duly compensated, it encouraged the audience who saw the opera to voluntarily put this in practice. Thus, operas established the directionality through selective processes for creating public communion even before revolutionary operas.

This study aims to investigate the related variables of self-esteem and depression among the Korean elderly people living alone and examine the relationships or interactions between those variables. Participants were 676 elderly men and women who were at least 65 years of age(M=76.17, sd=7.60) and lived in Seoul, Korea. Three hundred seventy eight participants of this study were living alone. Participants completed questionnaires and psychological tests including: Rosenberg's Self-Esteem Scale, Zung's Self-Rating Depression Scale, The Index of Activities of Daily Living(IADL), Social Support Index(SSI), and Life Satisfaction in the Elderly Scale(LSES). Main statistical designs were 2(gender)×2(residential types), Pearson-product moment and regression analysis. Results indicated that the elderly living alone recognized their health poorer, have lower economic status, and received less social supports than the elderly lived with others. The elderly men who had children were more likely to lived alone. And the elderly men living alone received less social supports than the elderly women living alone, and significant gender difference was found in the reason of living alone. The elderly men living alone had lower self-esteem than the elderly women living alone, while the elderly living alone showed more depressive symptoms than the elderly living with others. There were 2-way interactions both in self-esteem and depression by gender and residential types. There was highly significant gender difference in self-esteem only for the elderly living alone, and it was found that there was no significant difference in depression between elderly men living alone and women living with others. Regression analysis revealed that physical function and self-reported health are predictors of self-esteem, and physical function, self-reported health, and social support are predictors of depression for the Korean elderly living alone. These findings reiterate the role of physical function, social support, health in self-esteem and depession among the elderly and suggest the gender role for quality of life among the Korean elderly living alone.

At this moment, a paradigm shift is taking place across all sectors of society for the transition movements to the digital economy. Various movements are taking place in the global agricultural industry to achieve innovative growth using big data which is a key resource of the 4th industrial revolution. Although the government is making various attempts to promote the use of big data, the movement of the agricultural industry as a key player in the use of big data, is still insufficient. Therefore, in this study, effects of performance expectations, effort expectations, social impact, facilitation conditions, based on the Unified Theory of Acceptance and Use of Technology(UTAUT), and innovation tendencies on the acceptance intention of big data were analyzed using the economic and practical benefits that can be obtained from the use of big data for agricultural-related companies as moderating variables. 333 questionnaires collected from agricultural-related companies were used for empirical analysis. The analysis results using SPSS v22.0 and Process macro v3.4 were found to have a significant positive (+) effect on the intention to accept big data by effort expectations, social impact, facilitation conditions, and innovation tendencies. However, it was found that the effect of performance expectations on acceptance intention was insignificant, with social impact having the greatest influence on acceptance intention and innovation tendency the least. Moderating effects of economic benefit and practical benefit between effort expectation and acceptance intention, moderating effect of practical benefit between social impact and acceptance intention, and moderating effect of economic benefit and practical benefit between facilitation condition and acceptance intention were found to be significant. On the other hand, it was found that economic benefits and practical benefits did not moderate the magnitude of the influence of performance expectations and innovation tendency on acceptance intention. These results suggest the following implications. First, in order to promote the use of big data by companies, the government needs to establish a policy to support the use of big data tailored to companies. Significant results can only be achieved when corporate members form a correct understanding and consensus on the use of big data. Second, it is necessary to establish and implement a platform specialized for agricultural data which can support standardized linkage between diverse agricultural big data, and support for a unified path for data access. Building such a platform will be able to advance the industry by forming an independent cooperative relationship between companies. Finally, the limitations of this study and follow-up tasks are presented.

The initial situation in our tale shows that the earth-mother-feminine principle disappeared from the center of the collective consciousness into the collective unconscious. Therefore the heaven-father-masculine principle is dominant, which is represented by the king. And in the king's daughter, who is living without mother, the positive father complex is working. She stays in the heaven-spirit world playing with the golden ball, which can be seen as the state of inflation. She is disconnected from the earth-mother-feminine principle, which is important for a woman to find her genuine feminine identity. This demanded principle approaches her through the frog, a bewitched prince. Psychologically it means that a man is under the power of the negative mother complex. The disgusting, ugly frog is a symbol for the shadow, the earthly animal instincts of the princess. Only with his help she can find her golden ball again, which has fallen into the deep well. Their talk about the rewards to him for his help shows us very well the opposites. The frog wants the feminine value such as relation, earthly eros, but the princess offers the masculine value such as heavenly logos. After the frog brought her the lost ball, i.e. she regained her libido, she completely forgot her promise. Like this the content, which is becoming conscious, here the shadow, is easy to fall back into the unconscious and to be repressed. The frog cannot be with the princess without the help of the king, a father figure, a firm protector of the collective oder. At first unwillingly the princess obeys Logos of her father. But her authentic instinctual urge grows stronger and it causes that her ego is released from the power of her father complex. At just this moment the frog turns into a prince, i.e. he is liberated from the mother complex. The marriage of princess and frog-prince symbolize the unification of the opposites: heaven becomes earthly and earth becomes heavenly. Three iron bands, wrapped around the heart of Heinrich, a young king's servant, are snapped, while he brings the prince and princess back to his kingdom. The heart, the place of earth-mother-feminine consciousness, is now liberated. This principle, which disappeared into the unconscious, emerged into the collective consciousness and the wholeness is recovered. The Self is now leading the collective consciousness, which includes not only the principle of Logos but also Eros.

A study on a Russian fairy tale entitled "Seven Stars" was conducted from the perspective of analytical psychology. The plot goes as follows. Once upon a time, a village in Russia was suffering from severe drought. Villagers were dying of thirst, and crops were withering day by day. One night, a little girl left their house carrying a wooden dipper to find water for her sick mother by herself. However, water was nowhere to be found. She felt tired and fell asleep. When she woke up, the moon was already over her head, and the dipper had been filled with water. On her way home to give the water to her mother, she found a dog lying on the ground. The dog was also dying of excessive thirst, so she gave the dog a handful of water. Then the wooden dipper suddenly turned into a silver dipper. When she had finally arrived home and her mother has drunk the water, the silver dipper changed into a golden dipper. At that moment, an old man showed up and asked for water. The little girl gave him water. When the old man stared at the water, she realized that there were seven diamonds twinkling like stars in the dipper. The water never ran out. Surprisingly enough, the seven diamonds suddenly soared up into the sky and eventually formed a constellation of the Big Dipper. The water was shared with the other villagers who, then, recovered their strength. The severe drought came to an end, and the villagers danced together with joy. In this fairy tale, the severe drought symbolizes devastation caused by a unidirectional stream of consciousness while the little girl represents a new function, which shows the value of women who can heal and restore from that devastation. Symbolized in a fairy tale character such as 'a daughter' or 'a little girl', the new function eventually reaches up to the value which leads and affects the group as well as individuals. To conclude, this new function represents the unconscious process whose role is to revitalize the maternity and resolve the problems posed to a group as well as individuals.

This thesis presents the research of analytical psycholoy in respect of Jindo Dasiraegi. In a funeral of Jindo, situated in the southern island of Korea, there is a theatrical performance which is called Dasiraegi(rebirth). This research manifested a basic, universal meaning of psychological approach related the implicit of death in performing theatre from a analytic psychological point of view. The characteristics of this theatrical feast are like these ; 1) funeral festival 2) entrance of clown(the existence of antipole and conflict) 3) eroticism 4) active participation of female character 5) difficulty in her delivery 6) the moment of joy thanks to childbirth. The prerequisite of this feast should be a propitious mourning of person dying old and rich. That is, after having a complete life, it could be an entire death. Three main roles in Dasiraegi ; a bat-blind buddhist devotee, a strolling actor teasing men, an apostate monk, theses characters lock horns in a form of triangle conflict relations, then they keep a balance with a fake mourner as a protagonist , modulator and narrator. These characters are indeed clowns who manifested a metaphor as a decent, sacred and reasonable part of shadow regards group consciousness. The alive and the deceased, mourner and fake mourner, piety and confusion, wail and laugh, silence and grumble, death and birth, diverse antipole all coexist then theses are in harmony. The blind devotee and the monk are in antipole, the entertainer(anima) provokes a conflict between them. The infant is a solution as same as a result of conflict. This conflict seems to be eased by birth of a baby which is a symbol of wholeness(ganzheits) but the conflict of antipole is reenacted as insisting his parental right so this solution is leaving the baby to the chief mourner who is fourth character and the first beginning. Unconsciousness, hereby, is negotiating with appeared reality. The Images in unconsciousness are conscious and this new energy in unconsciousness is proceeding towards consciousness, then it became a therapeutic power for the loss of consciousness. Dasiraegi is the play of consolation much more for the alive than the deceased. The death signified not a loss but a resurrection and this intends a transition of new leading independent role for the alive. These make us have more prudent consideration concern the double sense of renewal for the dead and the alive. It is preserved as only a form of drama on stage after disappearance of Dasiraegi in a funeral recently. Dasiraegi was a manifestation of unconsciousness for compensation about the unilateral attitude of group consciousness to the strict death excessively. Therefore, this will enable reflect the relativeness and the attitude which regards the death as the end today.

This paper investigated the major history and reality of iconological composition for Jagyeongjeon Hall's flowered wall in Gyeongbokgung Palace, which was controversial in terms of preservation and management of cultural heritage. While analyzing the moment and cause of the flowered wall's renovation as it is now, modified or disappeared patterns were identified, and meaningfully misinterpreted congratulatory phrases were reviewed. The research results can be used as meaningful basic data when discussions are made for the restoration of the wall in the future. Jagyeongjeon Hall's flowered wall has reached the present day with large and small changes, but the inflection point that had a significant impact was the Joseon Expo (朝鮮博覽會) held at Gyeongbokgung Palace in 1929. This is because the wall that remained in the Jagyeongjeon Hall area was demolished to build an exhibition hall while preparing for the expo, and it was restored after the end of the event. It is highly likely that the modification or disappearance of the patterns constituting Jagyeongjeon Hall's flowered wall was also due to the restoration process carried out after the expo. There is a view that was transformed into its current state in the process of repair work carried out after the Korean War, but it is difficult to find any meaningful circumstances and evidence. Currently, character patterns known as 'Seongnidori(聖人道理)' are arranged on the inner wall of the section from Gyeongdomun Gate(擎桃門) to Yeogangmun Gate(如岡門), but considering the design form and example, it can be read as 'Seongjasinson(聖子神孫)'. The inner wall of the section from Yeogangmun Gate to Yeonsumun Gate(燕壽門) was originally made in the form of a flowered wall, and the phrases presumed to be 'Gyegyeseungseung(繼繼繩繩)' and 'Cheonse(千世)' were arranged. In the case of the section from Yeonsumun Gate to Hamgyumun Gate(含奎門), the inner wall where the pattern has disappeared is originally composed of geometric and character patterns, and there were also phrases specified as 'Cheonsu(千壽)' and 'Mansemansu(萬世萬壽)'. On the outer wall of the section from Yeonsumun Gate to Hamgyumun Gate, there is a possibility that the phrase known as 'Nakgangmanse(樂彊萬歲)' can be read as 'Cheonsemanse(千歲萬歲)'. In addition, the current outer wall was composed of one drawing board, but in the past, two drawing boards were composed separately.

Purpose : If electron, chosen for superficial oncotherapy, was applied with bolus, it could work as an important factor to a therapy result by showing a drastic change in surface dose. Hence the calculation value and the actual measurement value of surface dose of Treatment Planning System (TPS) according to four variables influencing surface dose when using bolus on an electron therapy were compared and analyzed in this paper. Materials and Methods : Four variables which frequently occur during the actual therapies (A: bolus thickness - 3, 5, 10 mm, B: field size - $6{\time}6$, $10{\time}10$, $15{\time}15cm2$, C: energy - 6, 9, 12 MeV, D: gantry angle - $0^{\circ}$, $15^{\circ}$) were set to compare the actual measurement value with TPS(Pinnacle 9.2, philips, USA). A computed tomography (lightspeed ultra 16, General Electric, USA) was performed using 16 cm-thick solid water phantom without bolus and total 54 beams where A, B, C, and D were combined after creating 3, 5 and 10 mm bolus on TPS were planned for a therapy. At this moment SSD 100 cm, 300 MU was investigated and measured twice repeatedly by placing it on iso-center by using EBT3 film(International Specialty Products, NJ, USA) to compare and analyze the actual measurement value and TPS. Measured film was analyzed with each average value and standard deviation value using digital flat bed scanner (Expression 10000XL, EPSON, USA) and dose density analyzing system (Complete Version 6.1, RIT, USA). Results : For the values according to the thickness of bolus, the actual measured values for 3, 5 and 10 mm were 101.41%, 99.58% and 101.28% higher respectively than the calculation values of TPS and the standard deviations were 0.0219, 0.0115 and 0.0190 respectively. The actual values according to the field size were $6{\time}6$, $10{\time}10$ and $15{\time}15cm2$ which were 99.63%, 101.40% and 101.24% higher respectively than the calculation values and the standard deviations were 0.0138, 0.0176 and 0.0220. The values according to energy were 6, 9, and 12 MeV which were 99.72%, 100.60% and 101.96% higher respectively and the standard deviations were 0.0200, 0.0160 and 0.0164. The actual measurement value according to beam angle were measured 100.45% and 101.07% higher at $0^{\circ}$ and $15^{\circ}$ respectively and standard deviations were 0.0199 and 0.0190 so they were measured 0.62% higher at $15^{\circ}$ than $0^{\circ}$. Conclusion : As a result of analyzing the calculation value of TPS and measurement value according to the used variables in this paper, the values calculated with TPS on 5 mm bolus, $6{\time}6cm2$ field size and low-energy electron at $0^{\circ}$ gantry angle were closer to the measured values, however, it showed a modest difference within the error bound of maximum 2%. If it was beyond the bounds of variables selected in this paper using electron and bolus simultaneously, the actual measurement value could differ from TPS according to each variable, therefore QA for the accurate surface dose would have to be performed.

Mobile commerce provides a convenient shopping experience in which users can buy products without the constraints of time and space. Mobile commerce has already set off a mega trend in Korea. The market size is estimated at approximately 15 trillion won (KRW) for 2015, thus far. In the Korean market, social commerce and open market are key components. Social commerce has an overwhelming open market in terms of the number of users in the Korean mobile commerce market. From the point of view of the industry, quick market entry, and content curation are considered to be the major success factors, reflecting the rapid growth of social commerce in the market. However, academics' empirical research and analysis to prove the success rate of social commerce is still insufficient. Henceforward, it is to be expected that social commerce and the open market in the Korean mobile commerce will compete intensively. So it is important to conduct an empirical analysis to prove the differences in user experience between social commerce and open market. This paper is an exploratory study that shows a comparative analysis of social commerce and the open market regarding user experience, which is based on the mobile users' reviews. Firstly, this study includes a collection of approximately 10,000 user reviews of social commerce and open market listed Google play. A collection of mobile user reviews were classified into topics, such as perceived usefulness and perceived ease of use through LDA topic modeling. Then, a sentimental analysis and co-occurrence analysis on the topics of perceived usefulness and perceived ease of use was conducted. The study's results demonstrated that social commerce users have a more positive experience in terms of service usefulness and convenience versus open market in the mobile commerce market. Social commerce has provided positive user experiences to mobile users in terms of service areas, like 'delivery,' 'coupon,' and 'discount,' while open market has been faced with user complaints in terms of technical problems and inconveniences like 'login error,' 'view details,' and 'stoppage.' This result has shown that social commerce has a good performance in terms of user service experience, since the aggressive marketing campaign conducted and there have been investments in building logistics infrastructure. However, the open market still has mobile optimization problems, since the open market in mobile commerce still has not resolved user complaints and inconveniences from technical problems. This study presents an exploratory research method used to analyze user experience by utilizing an empirical approach to user reviews. In contrast to previous studies, which conducted surveys to analyze user experience, this study was conducted by using empirical analysis that incorporates user reviews for reflecting users' vivid and actual experiences. Specifically, by using an LDA topic model and TAM this study presents its methodology, which shows an analysis of user reviews that are effective due to the method of dividing user reviews into service areas and technical areas from a new perspective. The methodology of this study has not only proven the differences in user experience between social commerce and open market, but also has provided a deep understanding of user experience in Korean mobile commerce. In addition, the results of this study have important implications on social commerce and open market by proving that user insights can be utilized in establishing competitive and groundbreaking strategies in the market. The limitations and research direction for follow-up studies are as follows. In a follow-up study, it will be required to design a more elaborate technique of the text analysis. This study could not clearly refine the user reviews, even though the ones online have inherent typos and mistakes. This study has proven that the user reviews are an invaluable source to analyze user experience. The methodology of this study can be expected to further expand comparative research of services using user reviews. Even at this moment, users around the world are posting their reviews about service experiences after using the mobile game, commerce, and messenger applications.

In Korea, this is the situation at moment that the total demand of timber in 1972 is more than 5 million cubic meters. On the other hand, however, the available domestic supply of timber at the same year is only about, 1 million cubic meters. A great unbalancing between demand and supply of timber has been prevailing. To solve this hard problem, it has been necessitiated to build up the forest stocks as early as possible with fast grown species such as poplar. Under circumstances, poplar plantations which have been carryed on government and private have reached to large area of 116,603 hectors from 1962 up to date. It has now be come a principal timber resources in this country, and required the basic study on various properties of wood for it's proper utilization, since it has not been made of any systematic study on the properties of Populus grown in Korea. In order to investigate the properties such as anatomical, physical and mechanical properties of nine different species (P. euramericana Guiner I-214. P. euramericana Guiner I-476, P. deltoides Marsh, P. nigra var. italica (Muchk) Koeme, P. alba L.,P. alba $\times$ glandulosa P. maximowiczii Henry, P. koreana Rehder, P. davidiana Dode) of poplar for their proper use and development of new ways of grading processing and quality improving, this study has been made by the Forest Research Institute.
