One of the famous Korean verses, Sijo 'In hemp clothes in winter(삼동에 베옷 입고)' is in thirty kinds of anthologies and ten kinds of Chinese writings. The major point in literary transmission of this work was the writer. The writer of this verse is Cho Sik(조식) in most anthologies. The writer of this work is recorded as Kil Jae(길재), Kim In-hoo(김인후), Kim Eung-jung(김응정), Lee Mong-gyu(이몽규) or Kim Ryung(김령) in Chinese writings. These people were famous for their studies and virtue, but they did not take office and retired from the world until they die. They were faithful to their principles serving their kings, though the country had wanted them to take a position in the government. Even though they did not in government service, they left some anecdotes and stories of lamentation after hearing their king's death. Because these stories and anecdotes can be easily connected with 'In hemp clothes in winter' which is about mourning over death of a king, they were known as the writer of this poem. Especially, their offsprings, juniors and followers often wrote these people as the writer of this work to represent their honor. Throughout the studies of several literary documents, this poem is written by Kim Eung-Jung, who lived in Kangjin(강진) in Jeonla province(전라도) and did not take office in all his life. He made this poem when he had heard the King Myoungjong(명종)'s death. Various transmission of literary documents with the records about 'In hemp clothes in winter' have a significance that can show the aspects of noble men's acceptance and transmission of Sijo.

In order to address many issues associated with large volume changes of silicon, which has very low electrical conductivity but offers about 10 times higher theoretical capacity than graphite (Gr), a silicon nanoparticles/hollow carbon (SiNP/HC) composite having bimodal-mesopores was prepared using silica nanoparticles as a template. A control SiNP/C composite without a hollow structure was also prepared for comparison. The physico-chemical and electrochemical properties of SiNP/HC were analyzed by X-ray diffractometry, X-ray photoelectron spectroscopy, nitrogen adsorption/desorption measurements for surface area and pore size distribution, scanning electron microscopy, transmission electron microscopy, galvanostatic cycling, and cyclic voltammetry tests to compare them with those of the SiNP/C composite. The SiNP/HC composite showed significantly better cycle life and efficiency than the SiNP/C, with minimal increase in electrode thickness after long cycles. A hybrid composite, SiNP/HC@Gr, prepared by physical mixing of the SiNP/HC and Gr at a 50:50 weight ratio, exhibited even better cycle life and efficiency than the SiNP/HC at low capacity. Thus, silicon/carbon composites designed to have hollow spaces capable of accommodating volume expansion were found to be highly effective for long cycle life of silicon-based composites. However, further study is required to improve the low initial coulombic efficiency of SiNP/HC and SiNP/HC@Gr, which is possibly because of their high surface area causing excessive electrolyte decomposition for the formation of solid-electrolyte-interface layers.

The utilized coefficient of friction (UCOF) as a ratio of the shear force to the normal force on the ground during walking is used to identify the point at which slip is likely to occur. Shoe walking will change the utilized coefficient of friction by shoe design such as sole thickness and hardness, heel shape, and outsole pattern. In this study, subjects are 21 adults (10 female, 11 male, age: $25.2{\pm}2.3yrs$, height: $165.6{\pm}7.2cm$), analysis variables were walking speed, GRF, when the UCOF is maximal, and Tangent of CoP-CoM angle, and correlation analysis with the utilized friction coefficient (UCOF). As a result, First, for the shod walking the time point which UCOF is maximum about heel strike was faster and the magnitude was larger than for barefoot walking. Second, the correlation between the tangent of CoP-CoM and UCOF of right foot was higher at the left heel striking point (UCOF2_h) which occurred in the post propulsion phase than at the right heel striking point (UCOF1_h). This suggests that the right foot UCOF is related to the braking phase of left foot( which is the propulsion phase of right foot) rather than the braking phase of right foot.

Triplet-triplet annihilation upconversion (TTA-UC) is a photochemical process wherein two or more low-energy photons are converted to a high-energy photon through a special energy transfer mechanism. Herein, we report a strategy to enhance the efficiency of TTA-UC through the light-scattering effect induced by silica microparticles (SM) embedded in polymeric thin films. By incorporating monodisperse uniform silica microparticles with a uniform size of 950 nm synthesized by $St{\ddot{o}}ber$-based seeded growth method into UC polymeric thin films, the UC intensity in the 430-570 nm range was enhanced by as much as 64% when irradiated by 635 nm laser. Analyzing the lifetime of PdTPBP phosphorescence revealed that the presence of SM in the UC layer does not affect triplet-triplet energy transfer (TTET) between sensitizers and acceptors, supporting the enhancement of TTA-UC originated from the light-scattering effect. On the other hand, the incorporation of SM in UC layer is shown to enhance the triplet-triplet annihilation (TTA) efficiency, which results in a 1.5-fold increase of the ${\Phi}_{UC}$, by scattering light source and thus increasing the number of excited photons to be utilized in TTA-UC process.

In church tradition, cultural misappropriation has often legitimized unjust hierarchy rather than to challenge it. Under the rubric of culturalism, Christian Education has served to justify the oppressive system and maintain status quo as well. A feminist theologian, Rebecca Chopp argues that the contemporary Western culture has intensified narcissistic individualism and self-referentiality and has supported the powerful, while forced the marginalized to be silent. Chopp insists that the role, nature, and mission of Christianity is to provide Word and words of emancipatory transformation. She advocates poststructural feminist theology and aims at renewal of the socio-symbolic order in society by criticizing assumptions underneath language, culture and politics. In this study, we will review the interview with an Asian-American couple and disclose the underlying assumptions and hegemony which have contributed to maintain the male domineering system. I suggest that Christian education for emancipatory transformation should encourage the oppressed women to reflect critically the existing order and to restore their own voice through constructive intervention facilitating "plurivociy" and "problem-posing" dialogue. Proclaimation of transformative Word can empower the marginalized people to revision the world alternatives to monotheistic patriarchal modernism.

Since the 2000s, Korean society has been transitioning into a multicultural society with a sharp increase in the influx of various non-Koreans including immigrant workers, immigrant spouses, international students, and refugees. As a result, Korea, which had maintained religious peace and coexistence as a multi-religious society, is showing signs of increased risks of social problems such as the surfacing of conflicts between religions. Religion can contribute to the integration and safety of communities in the process of becoming a multicultural society, but at the same time, it requires discussion from an educational perspective because of its ambivalence in potentially causing conflict within communities. Considering that one of the main functions of religion is social integration, religious education is required for the stable settlement of multicultural societies. In recognition of this, discussion regarding a new perspective on religious education is needed to respond to religious diversity and to understand the current society and the means of becoming a global citizen. This new discussion would be a 'general religious education' model that provides an education covering various religious and non-religious worldviews in order to cultivate 'religious literacy.' However, in a multicultural society, while general religious education may be useful in reducing prejudice and discrimination among students in an integrated environment, it should also be recognized that a 'special religious education' would be needed to acknowledge the unique values of each human group. This would be the most effective approach to multiculturalism. Therefore, this study proposes a form of 'cooperative religious education,' which combines general religious education and special religious education as a direction for religious education. In providing readers with background context, this study will review Korean religious policies and religious education, and then present realistic methods that can be implemented in schools.

In the event of a disaster occurring within a building, the prompt and efficient evacuation and rescue of occupants within the building becomes the foremost priority to minimize casualties. For the purpose of such rescue operations, it is essential to ascertain the distribution of individuals within the building. Nevertheless, there is a primary dependence on accounts provided by pertinent individuals like building proprietors or security staff, alongside fundamental data encompassing floor dimensions and maximum capacity. Consequently, accurate determination of the number of occupants within the building holds paramount significance in reducing uncertainties at the site and facilitating effective rescue activities during the golden hour. This research introduces a methodology employing computer vision algorithms to count the number of occupants within distinct building locations based on images captured by installed multiple CCTV cameras. The counting methodology consists of three stages: (1) establishing virtual Lines of Interest (LOI) for each camera to construct a multi-camera network environment, (2) detecting and tracking people within the monitoring area using deep learning, and (3) aggregating counts across the multi-camera network. The proposed methodology was validated through experiments conducted in a five-story building with the average accurary of 89.9% and the average MAE of 0.178 and RMSE of 0.339, and the advantages of using multiple cameras for occupant counting were explained. This paper showed the potential of the proposed methodology for more effective and timely disaster management through common surveillance systems by providing prompt occupancy information.

In order to understand the various cultural interactions caused by the wave of globalization, we need a proper lens that can observe and transmit correctly these phenomena. The result of understanding very differs depending on which lens is used. Translation can be regarded as a lens to communicate with each other in the world where language barriers exist. Literature is a kind of universal cultural heritage combined with the intellectual, artistic and social lifestyle of each society. Introducing this cultural complex, namely literature and impregnating people from other languages with the value of our Korean literature, begin with the correct translation. Translator should act as a literary missionary, not merely a simple communicator. The process of literary translation cannot be achieved by simple linguistic ability because it is a highly human scientific work that requires diverse talents from translators. The right translator for Korean literature in Romania is a person with diverse abilities and social experiences within the cultural framework of Korea and Romania. As the requirements of the translation environment from each country are different, the paradigm of foreign translation literature that Romania wants to accept may be very clear distinctively. With recognizing this characteristic environment of Romania, the value of Korean literature can be effectively spread in Romania. Translators are the creators of another original work. With this in mind, the education of Korean studies in Romania should pay more attention to the nurture of right and capable translators.

The purpose of this paper is to analyze the aspects of hybrid warfare and show the limits of jus in bello, a principle that evaluates the moral responsibility of the agents. As a theory of the morality of war presented in traditional warfare, the just war theory has been widely accepted. In particular, jus in bello offers the criteria of moral legitimacy regarding the actions of individuals participating in or involved in war. However, hybrid warfare, in which various aspects of warfare operate in a complex way, has obvious differences compared to traditional warfare, and this difference causes difficulties in determining the moral evaluation and attribution of responsibility for actions in war. In order to appropriately resolve the moral problems arising from hybrid warfare, it is necessary to clarify what the limitations of existing moral justification theories are. To this end, in this paper, we will first present a conceptual understanding of hybrid warfare, specify the differences from traditional warfare, and then show the limits of its application in hybrid warfare in light of the three principles that compose jus in bello.

The purpose of this study is to provide basic resources to the first-grade Home Economics Regular Teacher Qualification Program (FGHERTQP) in order to improve its operation plans. For the study, the three methods were carried out: an analysis on the curricula of FGHERTQP over six years since 2000, a questionnaire asking their satisfaction degrees and needs on the programs which was answered by the home economics teachers who were the participants of FGHERTQP, and several statistical analyses such as a descriptive-test, a $X^2$-test, a t-test, and one way ANOVA by using SPSS Win ver 10.0. The results of the study were as follows; Firstly, FGHERTQP has been operated ten times by five training centers during resent six years. Subject matters ($1{\sim}7$), whole numbers of lectures ($11{\sim}29$), and their allotted working hours ($111{\sim}136$) vary with individual training centers and operation years. Secondly, when using 5 point likert scales, Contents and Methods of evaluation marked 3.08 which were the lowest scores, and Qualification Training in General marked 3.72 which was the highest score among five fields of Qualification Training in General, Contents, Organizations, Methods and Evaluation. The overall scores were low. Thirdly, in needs analysis on offering subject matters, the participants wanted to study the field of home economics education more than that of subject contents. Looking about the highest needs classified by domains, Food Principles & Meal Management showed the highest in Foods. And Consumer Issues in Clothing & Textiles in Textiles, Upcoming Housing Cultures in Housing, Family Relationship in Child Development & Family Relationship, Juveniles and their daily life as a consumer in Family & Consumer Resources Management. Fourthly, training centers' lectures available had a significant influence on the satisfaction degrees according to general characteristic variations of the participants. That is, as a training center offers more lectures in the field of subject education than those of subject contents, the participants showed higher satisfaction degrees (p<.05).
