Reading at the Joseon Court: The Practice and Representation of Reading in the Sejong sillok (1418–1450)

( Giovanni Volpe ) 서울대학교 규장각한국학연구원 2023 Seoul journal of Korean studies Vol.36 No.1

We know more about how Joseon people wrote, and the texts they produced, than about how and why they read. Existing scholarship has primarily investigated Korean premodern texts from a linguistic and bibliographical perspective, while comparatively few approaches have centered on the social and cultural aspects of their reading. The present paper offers an understanding of how the practice of reading represented a key component of the ideological and institutional configuration of the state during King Sejong’s reign (1418-1450) by analyzing reading activities taking place in the context of the royal court as recorded in the Joseon wangjo sillok (Veritable records of the Joseon Dynasty) and other selected documentary and literary sources, mainly from the Kyujanggak archives. The paper starts by exploring the practice of reading in state rituals, assessing its significance as a public demonstration of royal authority. It then investigates how reading constituted a primary activity performed by the king, the crown prince, and other young male members of the royal family. Finally, it considers how the ruler actively used reading as an instrument of governance, assigning the reading of specific books as a strategy for reinforcing ideological and administrative control in and outside the royal palace.

L. Volpe,D. Batani,S. Baton,F. Perez,M. Koenig,Ph. Nicolai,B. Vauzour,J. J. Santos 한국물리학회 2011 THE JOURNAL OF THE KOREAN PHYSICAL SOCIETY Vol.59 No.51

Generation of high intensity and well collimated multi energetic proton beams from laser-matter interaction extend the possibility to use protons as a diagnostic to image imploding target in Inertial Confinement Fusion experiments in the framework of experimental road map of Hiper project (the European High Power laser Energy Research facility Project). Due to the very large mass densities reached during implosion processes, protons travelling through the target undergo a very large number of collisions which deviate protons from their original trajectory reducing Proton Radiography resolution below our expectations. Here We present a simple analytical model to study the Proton Radiography performance as a function of the main experimental parameters such as proton beam energy and target areal density. This approach leads to define two different criteria for PR resolution (called "strong" and "weak" condition) describing different experimental conditions.Finally numerical simulations using both Hydrodynamic and Monte Carlo codes are presented to validate analytical predictions.

나명익,홍아정,김용주,Marie Volpe 숭실대학교 영재교육연구소 2019 Global Creative Leader Vol.9 No.6

본 연구는 팀 구성원들의 다양성, 공유리더십, 팀 동적역량, 팀 효과성과의 영향관계를 파악하고, 공유리더십과 팀 동적역량의 매개효과를 검증하는데 목적을 두었다. 국내 기업 사무직에 종사하는 292명 64개팀을 대상으로 설문 조사하였고, 회귀분석과 연속다중매개분석을 SPSS 23.0 통계분석 프로그램을 활용하여 분석하였다. 연구분석결과 첫째, 팀 다양성, 공유리더십, 팀 동적역량, 팀 효과성에 대해 상관관계를 분석한 결과 모두가 유의한 상관관계를 보였으며 이중 팀 다양성은 나머지 변인 모두와 음의 상관관계를 갖는 것으로 나타났다. 둘째, 팀 다양성은 공유리더십과 팀 효과성에 부정적인 영향을 미치는 것으로 나타났고, 팀 동적역량에는 유효한 영향을 미치지 못하는 것으로 확인되었다. 또한 공유리더십과 팀 동적역량은 모두 팀 효과성에 긍정적인 영향을 미치는 것으로 나타났다. 셋째, 공유리더십은 팀 다양성과 팀 효과성을 부분매개하고, 팀 다양성과 팀 동적역량을 완전매개 하는 것으로 나타났다. 특히 공유리더십과 팀 동적역량은 팀 다양성과 팀 효과성과의 관계를 이중매개하는 것이 확인되었다. 이러한 연구결과는 기업의 성과단위인 팀이 목표와 책임의 공유, 수평적인 의사소통, 권한이양을 통한 구성원간 리더십 영향력의 활성화를 이루고, 자원을 탐색, 조정, 통합, 재배치하는 역량을 강화하게 된다면 더 높은 팀 효과성을 기대할 수 있으며, 팀 다양성의 부정적 효과를 줄이는 중요한 역할을 할 수 있음을 시사한다. The purpose of this study is to consider the implications of diversity management by investigating the influence of team diversity on team effectiveness and the mediating effects of shared leadership and team dynamic capability. Sixty four teams were selected from Korean companies and 292 team members participated in the questionnaire survey. Collected data was analyzed using SPSS 23. The results of the study shows that there were significant correlations among team diversity, shared leadership, team dynamic capability and team effectiveness, and that team diversity had a negative correlation with the rest of the variables. Second, team diversity had a negative influence both on shared leadership and team effectiveness, and did not have a valid influence on team dynamic capability. Shared leadership and team dynamic capability both had a positive influence on team effectiveness. Third, shared leadership partially mediated between team diversity and team effectiveness, and fully mediated team diversity and team dynamic capability. Lastly, shared leadership and team dynamic capability had double mediated effect between team diversity and team effectiveness. The findings of the study implies that in order to minimize the negative influence of team diversity, sharing visions, objectives, task method or norms with team members is crucial and providing diversity management systems and educational programs could be a starting point for developing organizational culture for managing team diversity. Facilitating shared leadership among team members will enhance team dynamic capability that could bring out the positive influence of team diversity and ultimately lead to company’s success.

The paper describes the key points contained in the short term HiPER (High Power laser Energy Research) experimental road map, as well as the results of two phases of the experiment performed in “HiPER dedicated time slots. Experimental and theoretical results of relativistic electron transport in cylindrically compressed matter are presented. This experiment was achieved at the VULCAN laser facility (UK) by using four long pulse beams (∽4 × 50 J, 1 ns, at 0.53 µm) to compress a hollow plastic cylinder filled with plastic foam of three different densities (0.1, 0.3, and 1 g cm−3). In the first phase of the experiment, protons accelerated by a picosecond laser pulse were used to radiograph a cylinder filled with 0.1 g/cc foam. Point projection proton backlighting was used to measure the degree of compression as well as the stagnation time. Results were compared to those from hard X-ray radiography. Finally, Monte Carlo simulations of proton propagation in cold and compressed targets allowed a detailed comparison with 2D numerical hydro simulations. 2D simulations predict a density of 2-5 g cm−3 and a plasma temperature up to 100 eV at maximum compression. In the second phase of the experiment, a short pulse (10 ps, 160 J) beam generated fast electrons that propagated through the compressed matter by irradiating a nickel foil at an intensity of 5 × 1018 Wcm−2. X-ray spectrometer and imagers were implemented in order to estimate the compressed plasma conditions and to infer the hot electron characteristics. Results are discussed and compared with simulations.

황수정,홍아정,홍지웅,Marie Volpe 중앙대학교 Human Engagement Institute 2022 역량개발학습연구 Vol.17 No.4

In this study, clusters were identified according to individual cognitive characteristics (occupational future time perspective) and motivational factors (goal orientation) for employees to accept changes and increase their adaptability. In addition, the study checked for differences in employee engagement by cluster. The study sample consisted of 514 employees working for Korean companies. The research problem was verified through cluster analysis and analysis of variance. Three groups were clustered; cluster 1 (‘cognitive lack performance type’), cluster 2 (‘time-aware learning type’), and cluster 3 (‘opportunity-aware performance type’). Employee engagement differed between the clusters, with cluster 2 showing the highest level of employee engagement, followed by cluster 3 and cluster 1. Existing studies have focused on the direct relationship between individual cognitive characteristics and motivational factors underlying employee participation. The present study adds value in that it combines two characteristics to distinguish and verify employee types.

The Impact of South-South Preferential Trade Agreements on Industrial Development: An Empirical Test

( Pablo Sanguinetti ),( Iulia Siedschlag ),( Christian Volpe Martincus ) 세종대학교 경제통합연구소 (구 세종대학교 국제경제연구소) 2010 Journal of Economic Integration Vol.25 No.1

Preferential trade agreements could lead to a reallocation of resources across sectors and countries. Production patterns resulting from North-North regional integration initiatives have been documented in several studies. However, empirical evidence on South-South trade agreements is limited. The purpose of this paper is to fill this gap in the empirical literature by looking at the effects of the establishment of MERCOSUR on manufacturing production patterns in Argentina, Brazil, and Uruguay over the period 1985-1998. We find that deepened preferential trade liberalization has fostered a reshaping of manufacturing production structures according to regional comparative advantage in labor and skilled labor. Furthermore, declining internal tariffs have weakened agglomeration forces determined by the distribution of market sizes. By using GMM estimation techniques, we ensure that these results are robust to endogeneity and serial correlation.

이 연구는 일터에서의 학습접근방식에 따라 주관적 경력성공에 미치는 영향에 차이가 있는지 살펴보고, 학습접근방식이 주관적 경력성공에 미치는 영향 관계에서 경력 메타역량의 매개효과를 검증하는 것을 목적으로 하였다. 총 303부의 설문 응답 자료를 SPSS 23.0과 AMOS 23.0을 활용하여 통계 분석을 실시하였다. 특히 학습 접근 방식은 심층학습접근, 피상-합리적 접근, 피상-무질서 접근으로 세 가지 구성 요소를 포함하였다. 그 결과는 심층학습접근 방식이 주관적 경력성공과 긍정적인 관련이 있음을 밝혔다. 그러나 피상-합리적 접근방식과 피상-무질서 접근방식은 주관적 경력성공에 유의한 영향을 미치지 않았다. 심층학습접근과 주관적 경력 성공 간의 관계는 경력 메타 역량에 의해 부분적으로 매개되었다. 이를 통해 조직과 인사담당자들은 구성원의 심층학습을 촉진하고 성찰 수준을 높일 수 있는 방안을 적극적으로 모색할 필요가 있으며 구성원은 새로운 업무와 교육 참여, 조직 내부, 외부의 다양한 네트워킹, 지속적인 학습을 통해 경험의 폭을 늘려가며 경력 정체성과 경력 적응성을 함께 강화해야 한다는 시사점을 도출하였다. The purpose of this study was to examine whether there is a difference in the effects of the learning approach in the workplace on subjective career success and to verify the mediating effect of career meta-competency in the relationship of the learning approach on subjective career success. Statistical analysis for 303 survey responses data was conducted using SPSS 23.0 and AMOS 23.0. In particular, the learning approach included three components: a deep learning approach, a superficial-rational approach, and a superficial-disordered approach. The results identified that the deep learning approach was positively related to subjective career success. However, the superficial-rational approach and the superficial-disordered approach was not significantly associated with subjective career success. The relationship between the deep learning approach and subjective career success was partially mediated by career meta competency. Organizations and HRD practitioners need to keenly seek ways to promote the deep learning and increase the level of reflection, and organization members should strengthen career identity and career adaptability by engaging in new tasks and educational opportunities, various networking inside and outside the organization, and continuous learning

Modulation of IL-18 Production in the Adrenal Cortex following Acute ACTH or Chronic Corticosterone Treatment

Kim, Yoon-Seong,Kim, Ho-Cheol,Sugama, Shuei,Volpe, Bruce,Baker, Harriet,Tinti, Cristina,Attardi, Barbara,Joh, Tong 경희대학교 동서의학연구소 2001 東西醫學硏究所 論文集 Vol.2000 No.-

Interleukin (IL)-18 is a proinflammatory cytokine and a stimulator of cell-mediated immune responses. We have previously reported that acute stress stimulates the production of IL-18 mRNA in the glucocorticoid (GC)-producing cells of the adrenal cortex. In order to investigate the mechanisms governing the expression of IL-18 in the adrenal cortex, the effects of acute ACTH or chronic corticosterone treatment on the level of IL-18 mRNA and protein were examined by in situ hybridization and Northern and Western blot assays. Adult male Sprague-Dawley rats received a subcutaneous injection of ACTH or subcutaneous implantation of slow-release corticosterone pellets followed by an injection of saline or ACTH. After 4 h, ACTH induced a 4-fold increase in IL-18 mRNA levels and elevated the content of pro-IL-18 peptide. Six days of chronic corticosterone treatment did not alter the basal levels of IL-18 mRNA and reduced those of pro-IL-18. Finally, ACTH treatment of animals under the corticosterone regimen induced a 2-fold increase in IL-18 mRNA and elevated the levels of the pro-IL-18 protein. The levels of the precursor, p45, and the active subunit p 10 peptides of the IL-18-processing enzyme, IL-1β-converting enzyme(ICE), showed no substantial differences in all the conditions tested. IL-1β was not detected under these experimental conditions. These data demonstrate that the production of IL-18 in the adrenal cortex is stimulated by ACTH treatment and is not inhibited by the direct action of corticosterone. In contrast to the anti-inflammatory action of GCs, IL-18 may have and immunostimulatory role during acute stress.

Reverse engineering of mechanical parts: A template-based approach

Buonamici, Francesco,Carfagni, Monica,Furferi, Rocco,Governi, Lapo,Lapini, Alessandro,Volpe, Yary Society for Computational Design and Engineering 2018 Journal of computational design and engineering Vol.5 No.2

Template-Based reverse engineering approaches represent a relatively poorly explored strategy in the field of CAD reconstruction from polygonal models. Inspired by recent works suggesting the possibility/opportunity of exploiting a parametric description (i.e. CAD template) of the object to be reconstructed in order to retrieve a meaningful digital representation, a novel reverse engineering approach for the reconstruction of CAD models starting from 3D mesh data is proposed. The reconstruction process is performed relying on a CAD template, whose feature tree and geometric constraints are defined according to the a priori information on the physical object. The CAD template is fitted upon the mesh data, optimizing its dimensional parameters and positioning/orientation by means of a particle swarm optimization algorithm. As a result, a parametric CAD model that perfectly fulfils the imposed geometric relations is produced and a feature tree, defining an associative modelling history, is available to the reverse engineer. The proposed implementation exploits a cooperation between a CAD software package (Siemens NX) and a numerical software environment (MATLAB). Five reconstruction tests, covering both synthetic and real-scanned mesh data, are presented and discussed in the manuscript; the results are finally compared with models generated by state of the art reverse engineering software and key aspects to be addressed in future work are hinted at.

Objective Amongst psychiatric disorders, major depressive disorder (MDD) is the most prevalent, by affecting approximately 15–17% of the population and showing a high suicide risk rate equivalent to around 15%. The present comprehensive overview aims at evaluating main research studies in the field of MDD at suicide risk, by proposing as well as a schematic suicide risk stratification and useful flow-chart for planning suicide preventive and therapeutic interventions for clinicians. Methods A broad and comprehensive overview has been here conducted by using PubMed/Medline, combining the search strategy of free text terms and exploded MESH headings for the topics of ‘Major Depressive Disorder’ and ‘Suicide’ as following: ((suicide [Title/Abstract]) AND (major depressive disorder [Title/Abstract])). All articles published in English through May 31, 2019 were summarized in a comprehensive way. Results Despite possible pathophysiological factors which may explain the complexity of suicide in MDD, scientific evidence supposed the synergic role of genetics, exogenous and endogenous stressors (i.e., interpersonal, professional, financial, as well as psychiatric disorders), epigenetic, the hypothalamic-pituitary-adrenal stress-response system, the involvement of the monoaminergic neurotransmitter systems, particularly the serotonergic ones, the lipid profile, neuro-immunological biomarkers, the Brain-derived neurotrophic factor and other neuromodulators. Conclusion The present overview reported that suicide is a highly complex and multifaceted phenomenon in which a large plethora of mechanisms could be variable implicated, particularly amongst MDD subjects. Beyond these consideration, modern psychiatry needs a better interpretation of suicide risk with a more careful assessment of suicide risk stratification and planning of clinical and treatment interventions.
