최용석,하태영 한국항해항만학회 2005 한국항해항만학회지 Vol.29 No.8

This paper proposes a method for designing layout on the yard and evaluating alternative designs of the layout by applying simulation. The design method is based on the concepts of the conventional port container terminal with yard layout. In general, yard design of the container terminal consists of the two major parts. One is to divide yard area between the number of sections and runs and the other is to decide the number of equipment including yard truck and yard crane. In the past days, this design was depended on the experience of the terminal operator and the reproduction of the conventional terminal layout because it is a very complex problem to be considering facilities and equipments. In this paper, we suggest a design method as a conceptual procedure used simulation method. The number of sections and runs on yard area, the number of yard truck per container crane, and the number of yard crane per run are decided using simulation. In addition, the traffic flow among blocks on yard layout is estimated in terms of rate. 본 연구는 시뮬레이션을 활용하여 장치장의 레이아웃을 설계하고 레이아웃의 대안설계를 평가하기 위한 방법을 제안한다. 설계방법론은 장치장 레이아웃을 가진 재래식 컨테이너터미널의 개념들을 기초로 한다. 일반적으로 컨테이너터미널의 장치장 설계는 두가지 부분으로 구성되는데, 하나는 섹션수와 런수간의 장치장 면적을 분리하는 것이고, 다른 하나는 야드트럭과 야드크레인과 같은 장비의 수를 결정하는 것이다. 과거에는 이 설계가 시설물과 장비들을 고려해야 하는 매우 복잡한 문제이기 때문에 재래식 컨테이너터미널의 복제와 운영자의 경험에 의존했다. 본 논문에서는 시뮬레이션 방법이 사용된 개념설계로서 장치장 설계 방법을 제안한다. 장치장 영역에서 섹션과 런의 수, 컨테이너 크레인당 야드트럭의 수, 런당 야드 크레인의 수 등이 시뮬레이션을 사용하여 결정된다. 추가로 장치장 레이아웃에서 블록간의 통행량 흐름이 비율별로 추정된다.

지역사회 문제해결형 기업가정신 교육과정 개발: 역량 기반 교육과정 설계를 기반으로

최용석,박종석,백보현 한국벤처창업학회 2022 벤처창업연구 Vol.17 No.5

As the economic, social, and environmental problems of the local community reach a serious level, our society is realizing the need to foster young talents who discover opportunities in local issues through entrepreneurship education and create social values through creative challenges. However, entrepreneurship education programs are generally focused on commerciality, so customized education programs to solve regional problems are insufficient. Therefore, this study aimed to develop a community problem-solving entrepreneurship curriculum. In this study, a competency based curriculum model was applied to develop the curriculum, and regional problem-solving entrepreneurship competencies were derived through expert advice from a total of 10 people. In the process, the Delphi methodology was additionally used to reduce the possibility of errors in the competency model. As a result of the study, a total of 23 regional problem-solving entrepreneurship competencies were confirmed, and knowledge(K) - skill(S) - attitude(A) by competency consisted of 5, 9, and 9, respectively. By applying this to Dunham's problem-solving six-step model, modular learning support measures were developed in the order of phase 1(problem discovery), phase 2(problem analysis), phase 3(plan), phase 4(measure), and phase 5(evaluation). This study is meaningful in that it integrated theory and practice by developing specific entrepreneurship curriculum and learning support measures based on the theoretical model devised in social welfare. In addition, it has implications in that it developed a regional problem-solving entrepreneurship competency model based on expert advice and proposed a specific curriculum based on this. 지역사회의 경제, 사회, 환경 문제가 심각한 수준에 이르자, 우리 사회는 기업가정신 교육을 통해 지역문제에서 기회를 발견하고 창의적 도전을 통해 사회적 가치를 창출하는 청년 인재 육성의 필요성을 절감하고 있다. 그러나 기업가정신 교육 프로그램은 대체로 상업성에 방점을 두고 있어 지역문제 해결 맞춤형 교육 프로그램이 미비한 상황이다. 이에 본 연구에서는 지역사회 문제 해결형 기업가정신 교육과정을 개발하는데 연구의 목적을 두었다. 본 연구는 교육과정 개발을 위해 역량 중심 교육과정 모형(Competency based Curriculum)을 적용하였으며, 총 10인의 전문가 자문을 거쳐 지역문제 해결형 기업가정신 역량을 도출하였다. 그 과정에서 역량 모형의 오류 발생 가능성을 낮추고자 델파이 방법론을 추가로 활용하였다. 연구 결과, 총 23개의 지역문제 해결형 기업가정신 역량이 확정되었으며, 역량별 지식(K)-기술(S)-태도(A)는 각각 5개, 9개, 9개로 구성되었다. 이를 Dunham의 문제해결 6단계 모형에 적용하여 Phase 1 문제 발굴, Phase 2 문제 분석, Phase 3 계획, Phase 4 조치, Phase 5 평가 순으로 모듈식 학습지원책을 개발하였다. 본 연구는 사회복지학에서 자안된 이론적 모형을 기반으로 구체적인 기업가정신 교육과정 및 학습지원책을 개발함으로써 이론과 실천을 통합하였다는 점에서 의미가 있다. 또한 전문가 자문을 토대로 지역문제 해결형 기업가정신 역량 모형을 개발하고 이를 근거로 구체적인 교육과정을 제안하였다는 점에서 시사점이 있다.

Histone deacetylase inhibitor KBH-A42 inhibits cytokine production in RAW 264.7 macrophage cells and in vivo endotoxemia model

In light of the anti-inflammatory properties of histone deacetylase (HDAC) inhibitors, such as suberoylanilide hydroxamic acid (SAHA) and trichostatin A (TSA), we examined a new HDAC inhibitor KBH-A42 for its anti-inflammatory activities. KBH-A42 showed noteworthy anti-inflammatory properties in vitro via suppression of the production of TNF-α, a proinflammatory cytokine, and nitric oxide (NO), a proinflammatory effector molecule, in LPS-stimulated RAW264.7 cells and peritoneal macrophages. It also inhibited TNF-α production in vivo as demonstrated in a LPS-induced mouse endotoxemia model. The levels of TNF-α, IL-1β, IL-6 and iNOS mRNAs determined by RT-PCR propose that the inhibition of these pro-inflammatory mediators by KBH-A42 resulted from inhibiting expression of these genes. However, the EMSA study to see the effect of KBH-A42 on the binding of NF-κB, a transcription factor, to a specific DNA sequence showed that the binding of NF-κB to DNA was not changed regardless of increasing the concentration of KBH-A42 in the presence and absence of LPS stimulation. Interestingly, DNA binding of another transcription factor AP-1 dose-dependently increased by KBH-A42. KBH-A42 differentially regulated the phosphorylation of MAP kinases. While the phosphprylation of ERK1/2 and SAPK/JNK was not affected by KBH-A42, the phosphorylation of p38 decreased by KBH-A42. These results showed that KBH-A42 inhibits production of proinflammatory cytokines in macrophages by decreasing their mRNA levels, and p38 kinase is involved in the KBH-A42-mediated inhibition.

IPA를 활용한 관광지 축제 평가: 제주레저힐링축제 중심

최용석,김지원 한국콘텐츠학회 2023 한국콘텐츠학회논문지 Vol.23 No.11

The primary objective of this study is to investigate the direction of the Jeju Leisure Healing Festival, an event hosted in Jeju, South Korea. To accomplish this objective, the study intends to evaluate the importance and satisfaction levels of festival attributes among festival participants and represent these findings within an IPA matrix to establish attribute priorities. Furthermore the study aims to distinguish variances from prior research on the festival through the application of the IPA method and incorporate these discoveries into the analysis of results and their implications. The research findings highlight several areas that require notable improvements, including pre-festival promotion, on-site information and guidance, and parking convenience. On the other side, factors such as the proximity of festival venues to tourist attractions and the uniqueness of programs have been recognized as aspects to be either avoided or considered for future development. It is imperative to examine these outcomes in light of the festival venue's identity as an active tourist destination. This sheds light on visitors' perspectives regarding the festival content offered on Jeju Island.

Shaping Up in the Domestic Market to Export Innovated Product Varieties

최용석,한진희 동국대학교 사회과학연구원 2023 사회과학연구 Vol.30 No.3

This paper examines the process from product variety innovation to exporting using a plant-product dataset for Korean MFG, focusing on the role of domestic market for exporting. We find there are two types of exporters of the innovated product varieties: 1) instant exporters which begin producing and exporting in the same year, and 2) delayed exporters which begin exporting the innovated varieties after some production experience in the domestic market. Compared with instant exporters, the delayed exporters tend to be less productive, smaller, and less likely to have previous exporting experience, but more likely to be engaged in R&D. While producing for the domestic market only, delayed exporters become more productive and capital- and skill-intensive, increase R&D and capital investments, and scale up the production of the innovated product varieties. We provide some evidence that these changes are related to future exporting.
