This study dealt with two case studies of the development of beginning science teachers' pedagogical content knowledge (PCK). This study was grounded on the idea that teacher thinking and classroom behavior are related to each other in a reciprocal way. Teachers' PCK influences teaching practices, while in a reverse way teaching activities influence teachers' practical knowledge. Two beginning science teachers participated in this study. Data collection consisted of classroom observation, interviews, reflective journals and lesson plans. For data analysis, we conceptualize pedagogical content knowledge for science teaching as consisting of four components: (a) knowledge about science matter, (b) knowledge about students' understanding of science topics, (c) knowledge about instructional strategies for teaching science, (d) knowledge about assessment in science. The outcomes of this study revealed that there was a large gap between beginning science teachers' intentions for teaching science and their practice. To give beginning teachers more opportunities to incorporate their knowledge base for teaching, we propose that they need to be involved in a real teaching situation at schools rather than in the university.

The aims of this research are to analyze the representations and conceptual sequence of eye vision in Korean science textbooks and to suggest a contents construct about eye vision where the conceptual sequence is considered. Research method was literature review, and the literatures that were used for analysis were the 7th Korean science curriculum which was revised in 1997, and the science and physics textbooks developed based on the 7th Korean science curriculum. The research results are as follows: 1) Although the science curriculum seems to have no problem on sequence in the eye vision concepts, the science and physics textbooks based on the curriculum reveal problems on the sequence in the eye vision concepts; 2) Some Korean science textbooks explain retinal image formation according to the Alhazen's idea, except in inverse image; 3) Some Korean science textbooks explain about the reasons of near- and far-sightedness without consistency between the textbooks for 7th and 8th grade students; 4) A few Korean science textbooks give an inappropriate explanation about the principle of eye sight correction by eye glasses; 5) According to the analysis result, the concepts related to eye vision should be presented in the order of explanation about light refraction phenomena, image formation process by convex lens, structure of human eye and retinal image formation process, correction of eye sight using lens.

Time can be the fundamental basis of religious doctrine and the foundation for a life of faith. Therefore, understanding a religion's interpretation of time and exploring its perception is accepted as one of the approaches to comprehending its principles. Based on this idea, this article delves into how chronos (measured time) and kairos (experienced time) are manifested in Daesoon Jinrihoe. In Daesoon Jinrihoe, the moment when chronos and kairos intersect is considered a moment of spiritual experience. Ethical codes are accomplished in the midst of the process of defining this time as the Heavenly Dao and adjusting human affairs accordingly. These ethics lead individuals towards a religious life. East Asian traditions also apply this logic, but Daesoon Jinrihoe differs in that it emphasizes reinterpreted ethics. Furthermore, Daesoon Jinrihoe posits that Degree Numbers (度數) are a device that ensures the transition from chronos to kairos. Degree Numbers, which are both a law of the universe's motion and a function of time, were emphasized by the Kang Jeungsan when he advocated for the discarding of old ways and the creation of the new ways. He thereby urged humans to live in accordance with time. Time is also facilitated in the dimension of ritual observances and participation, with examples including prayers, devotional offerings, and holy works (gongbu, 工夫). Those rituals of Daesoon Jinrihoe actively incorporate a unique basis of reason for this style of engagement with time, which is one of the aspects that is held to secure justification.

The purpose of this study is to design an effective innovation model for communication-centered public services, based on the case of Korea Midland Power Co., Ltd (KOMIPO). This study analyzed customer and employee participation activities at KOMIPO, focusing on communication activities to derive the best practices. The study comprised of the following stages: (1) Preparation stage to assess the current situation and promote change management; (2) Problem-solving stage for improving public services; (3) Problem-solving stage for improving work processes; (4) Problem-solving stage for strengthening collaboration, and (5) Design stage for an innovation model. Based on the results of this study, an innovation model was developed for public services by applying the double-diamond design process. The proposed model presents a process structure, which is derived through an iterative process of primary divergence (discovery) and convergence (definition), and secondary divergence (development) and convergence (delivery). This study also proposed the possibility of applying the Idea-Power-Plant activities of KOMIPO's best practices to the proposed model. While this study proposed an innovation model for communication-centered public services through the analysis of a specific public company, the results of the study provide broad insights for effective operations management through efficient communication based on the participation of customers and employees in public institutions.

Objectives : The purpose of this study was to investigate individual- and community-level factors on suicidal ideation and suicide attempt among Korean adults. Methods : This study was conducted on 225,965 adults collected through data from the 2021 Community Health Survey and the Korean Statistical Information Service (KOSIS). The general characteristics, suicidal behavior (e.g., suicidal ideation, and suicide attempts), and community-level characteristics of the study subjects were analyzed using frequency (%) and mean (standard deviation). The effects on individual- and community-level factors on suicidal ideation and suicide attempts was analyzed using multilevel logistic regression models. Results : The community-level factor associated with suicidal ideation was unmet health care (Odds Ratio [OR]=1.053, 95% CI=1.035-1.071), and the community-level factor associated with suicide attempt was the aging rate (OR=1.015, 95% CI=1.001-1.030). Regarding health-related variables, the individual-level factors associated with suicidal ideation were stress status (OR=9.388, 95% CI=8.629-10.213), depressive experience in the past year (OR=6.737, 95% CI=6.454-7.032), and the predominantly individual-level factors associated with suicide attempt were also stress status (OR=5.213, 95% CI=3.699-7.347), and depressive experience in the last one year (OR=13.433, 95% CI: 11.247-16.044). Conclusions : We confirmed individual-level and community-level factors influencing suicidal ideation and suicide attempt. Through these findings, we need to establish suicide prevention policies, considering managing individual-level factors such as stress and depression as well as community-level factors such as unmet health care.

The purpose of this paper is to restore the academic status of Gungwi perception a little. The symbolism of Gungwi, or Year Month Day Hour, likened to Geun Myo Hwa Sil, is not just a technique of interpretation. Recognizing that it corresponds to Saju's most fundamental Mingli principle, the study was conducted to the effect that more academic research should be conducted in the future. The intrinsic idea that constitutes Saju is the yin-yang and the five elements, the letters recorded are twelve-dimensional, and the elements in charge of the space and time are Cheongan, Jeeji, and Gungwi, which are woven into four pillars. Through this consideration of Gungwi's perception, we presented the "spectrum of time" phenomenon that past time and information pass through the point of time, spread like a spectrum, and lead future time and action at the time when humans are born, that is, the energy of the universe is formatted throughout the brain and body. We discussed the change point of Eight Trigrams used by Lim Cheol Cho as a basis for explaining 'Won Hyong I Jeong' and the assumption that the time change or distortion of the two cones penetrating the present, which is assumed in parallel theory, one of the modern cosmologies, leaves an afterimage in the future universe as Gungwi's deductive basis.

Recently there are many development and support policies for start-up companies because of successful venture companies related to ICT services. However, as these policies have focused on the support for the initial stage of start-up, many start-up companies have difficulties to continuously grow up. The main reason for these difficulties is that they recognize start-up tasks as independent activities. However, many experts or related articles say that start-up tasks are composed of related processes from the initial stage to the stable stage of start-up firms. In this study, we models the start-up processes based on the survey collected by the start-up companies, and analyze the start-up process of ICT service companies with process mining techniques. Through process mining analysis, we can draw a sequential flow of tasks for start-ups and the characteristics of them. The analysis of start-up businessman, idea derivation, creating business model, business diversification processes are resulted as important processes, but marketing activity and managing investment funds are not. This result means that marketing activity and managing investment funds are activities that need ongoing attention. Moreover, we can find temporal and complementary tasks which could not be captured by independent individual-level activity analysis. Our process analysis results are expected to be used in simulation-based web-intelligent system to support start-up business, and more cumulated start-up business cases will be helpful to give more detailed individual-level personalization service. And our proposed process model and analyzing results can be used to solve many difficulties for start-up companies.

This paper examines the apparition of the Virgin Mary revealed in Rue du Bac, Paris, France, in 1830, from a perspective of analytical psychology. To do so, it amplifies the archetypal motifs manifested in the images of the Virgin Mary of Rue du Bac by introducing the medieval alchemical picture titled "Glorification of the body portrayed as the coronation of the Virgin Mary" from Reusner's Pandora (1588). This image of the Virgin Mary is full of archetypal motifs that show the process and end result of individuation, which is the main idea of Jungian psychology. These symbols that depict the individuation process, both in Reusner's Pandora and in the Mary of Rue du Bac, are expressions of mythologems, constituent elements of the collective unconscious. Jung noted that these mythologems are the ultimate base and matrix of all religions. Through examining the archetypal motifs, which appear in the Mary of Rue du Bac, the apparition of the Mary turns out to be the revelation of the archetypal image of the Self in a space-time continuum, which is constellated in the collective unconscious. That is, an archetypal figure revealed itself to a witness' ego-consciousness to whom a space-time continuum functions as a cognitive category. The Mary of Rue du Bac represents the union of the opposites of divinity and humanity, which lacks in the symbolism of the Cross in Christianity. In this regard, she is an image of the new savior, who opens the new aeon of the Aquarius. The revealed image of Mary shows that divinity originates from the inner realm of the human psyche, that corporeal human beings are the matrix in which the divine incarnates, and that human being is the subject of psychological redemption. The image of Mary awakens us to the value of divinity in the human psyche in the times when the spiritual values Christianity has retained declines drastically.

Recently, major advanced countries are fostering megacities through policy for reasons such as solving population problems, political and economic issues, and strengthening national competitiveness. The trend of change is accelerating. In Korea, following Seoul and Gyeonggi, mega city policies are being promoted in Busan, Ulsan, Gyeongnam, Daegu and Gyeongbuk, Gwangju and Jeonnam, and Daejeon, Sejong, South Chungcheong and North Chungcheong areas. Due to this urbanization phenomenon, military experts predict that the future battlefield environment will be space or a large city (mega city). From this perspective, Korea will not be able to effectively respond to the threats facing megacities if it does not prepare in advance. Therefore, underground facility operation capabilities optimized for the huge scale of the mega city and the characteristics of the underground operational environment are required. Against this background, the characteristics of the underground operational environment of mega cities and cases of preparation for underground facility operations in advanced military countries such as the United States and Israel were analyzed. Based on this, the capabilities required for underground facility operations suitable for the underground operational environment within Korean megacities are developed from an idea perspective to military organization and combat system, securing special equipment and materials to ensure combatant survival, developing small unit combat techniques, and establishing a training system. It was presented with priority given to.

The House that Jack Built (2018), a film about how the protagonist Jack is reborn as a "mad artist" with psychotic symptoms during a 12-year killing spree, provides an interesting opportunity to analyze the film in terms of psychoanalysis and religion. Jack, an engineer who suffers from OCD, finds pleasure in the accidental murder of a character and considers killing people as an art form, overcoming his OCD in the process. The question we are interested in is whether the symptoms of OCD are truly overcome by the act of repeated killing. The idea is that Jack's OCD is not overcome by killing, but rather that the symptoms disappear as he moves from neurosis to a stabilized psychotic state. According to the theory of the famous French psychoanalyst Lacan, the hallucinations or delusions that human subjects experience when they lose their realistic stability are a phenomenon that occurs when they are confronted with The Real, which penetrates through the cracks of the symbolic system. Phenomena such as Jack's illusory reality and delusions in the movie are pathological symptoms of the absence of a paternal figure in his life, causing the Name-of-the-Father to fail to take hold. This paper deciphers the psychotic structure of Jack, the protagonist of Lars von Trier's House of Jack, through Lacanian psychoanalysis.
