There have been lots of studies on locational factors of companies, but, very few studies for Korean shipping companies. This study analyzes locational factors for Korean shipping companies using AHP(Analytic Hierarchy Process) method. For the study model, the first level is consisted by software, hardware and city policy factors. As more specific factors, the second level is formed by three factors of the first level. The third level consists of Seoul and Busan to evaluate competitive advantage for location of shipping companies. We carried out an analytical survey focused on the executives of shipping companies and related experts, and derived the priority order for locational factors of Korean shipping companies as follow. Firstly, software factors turned out the most important factor for location of Korean shipping companies. Next, Busan has a competitive advantage only in city policy factors. However, there are much of competitive disadvantages in both software and hardware factors for location of shipping companies compared against Seoul.

This paper aims to investigate the causal relationship between geopolitical risk and stock price volatility in the shipping industry. Given its international nature and dependence on global trade, this industry is exposed to various uncertainties and risk factors. This study specifically focuses on the impact of geopolitical risk, which has gained significant attention in recent years due to events such as the Russia-Ukraine War and the Israel-Hamas War. To analyze this relationship, the study utilizes vector autoregressive model-based causality tests. The research estimates the causal relationship between geopolitical risk indicators and the stock price volatility of five shipping companies listed on the Korea Exchange. The study covers the period from 2000 to 2023. The results indicate the following: Firstly, an increase in geopolitical risk leads to a rise in stock price volatility for shipping companies. Moreover, the impact of actual geopolitical events, rather than just diplomatic disputes, is statistically significant. Lastly, the impact of geopolitical risk is particularly significant in the bulk shipping sector.

Following the collapse of Hanjin Shipping, building a strong maritime cluster is one of the policy measures for the re-construction of the Korean shipping and shipbuilding industries. Thus, the purpose of this study is to develop a policy alternative for building a maritime cluster. Using Porter's diamond models, we analyzed the Imabari maritime cluster of Japan, which is characterized by cooperation between key industries, such as shipping, shipbuilding, shipbuilding equipment, and finance. The Imabari Maritime Cluster is equipped with complete domestic demand conditions and related supporting industry conditions. Although the strengths of the production conditions include excellent family-based management and strong support from regional administration and banks which develops independency among cluster members, the weak points include the absense of robust port services and difficulty in recruiting young talent in small and medium-sized cities. We can confirm that the company's strategy is focused on stable management, rather than a short-term view.

Background: This case study suggests the potential usefulness of Korean medicine treatment with herbal medicines for shoulder pain and improving the quality of life of patients with frozen shoulder. Case Summary: A patient had shoulder pain and decreased daily living function due to frozen shoulder. Korean medicine treatments, including herbal medicine; acupuncture at points TE14, HT1, BL11, SI10, and LI15; and pharma-acupuncture containing Sinbaro, were applied for 31 days. The Numeric Rating Scale scores for shoulder pain decreased from 7 to 4, and the Shoulder Pain and Disability Index scores decreased from 71.54 to 66.15, with an increase in range of motion from 30° flexion, 60° abduction, and 10° external rotation to around the normal range of motion. Conclusion: Korean medicine treatment can be considered an effective conservative management option for pain and decreased daily living function in patients with frozen shoulder.

Objectives: This study reports on the efficacy of Korean medical treatments for a functional dyspepsia patient with panic disorder and lower back pain. Methods: A 51-year-old male patient with functional dyspepsia was treated with herbal medicines and acupuncture for 17 days. The treatment effect was evaluated by measurements drawn from the Numerical Rating Scale, range of motion, Oswestry Disability Index, European Quality of Life 5 Dimensions Scale, and Gastrointestinal Symptom Score. Results: Following the treatment, the patient showed a decrease on the Numerical Rating Scale and Oswestry Disability Index and in Gastrointestinal Symptom Score, as well as an improvement in range of motion and European Quality of Life 5 Dimensions score. Conclusions: Korean medical treatments appear to be effective in reducing functional dyspepsia. Further clinical research on patients with functional dyspepsia is needed.

Objective: This study aimed to report the effects of Korean medicine in treating a patient with peripheral facial nerve palsy. Methods: The patient received Korean herbal medicine and pharmacopuncture and acupuncture treatment for 14 days. We measured the House-Brackmann (HB) scale, Yanagihara's unweighed grading system (Yanagihara's score), and the numeric rating scale (NRS) to assess symptom changes. Results: After treatment, the patient showed decreased HB, Yanagihara's, and NRS scores. Conclusion: The results indicate that Korean medicine, including Korean herbal medicine and pharmacopuncture and acupuncture treatment, is effective in the management of patients with peripheral facial nerve palsy. Further clinical research on this patient group is needed.

The purpose of this study was to extract and evaluate the factors to improve the quality of shipping logistics platform suggested as an alternative to the stagnant shipping logistics industry. For this, we selected factors through previous research and expert interviews, and conducted surveys on carriers, forwarders, shippers, and platform operators with experience using shipping logistics platforms. As a method of analysis, quality evaluation of the shipping logistics platform was conducted using IPA (Importance-Performance Analysis). The results of this study are as follows "Competitiveness of services provided", "Connectivity with other transportation mode", "Competitiveness of freight", "Transparency of freight", and "Stability of booking space". For the shipping logistics platform to be activated in the future, priority should be given to focusing on these factors. This study has academic significance for establishing configuration function of shipping logistics platform and deriving evaluation factor. Additionally it is an industrial significance for suggesting strategies to improve users' participation in the shipping logistics platform.

This research studies the shipping industry rationalization of 1984 and the 2009 shipping industry restructuring and policy to raise competitiveness. According to this research the operation of the two policies showed significant difference in the enforcer, aim and policy contents. In 1984, under government initiative, M&A of shipping companies was accomplished but in 2009 restructuring of shipping companies is being pushed ahead by the group of creditors. The use of different policies, M&A of shipping companies and restructuring of insolvent shipping companies, as solutions in a crisis shows different characteristics. The act of shipping industry rationalization in 1984 was proposed on the very basic and aggressive aim and targeted to improve Korea's shipping industry structure. On the other hand, the 2009 policy of the restructuring of the shipping companies and improving competitiveness was based on the protective concept. This policy aimed for a prevention of bankruptcy of the shipping companies and hence preserve the shipping industry.

1970년부터 해운대 신시가지 조성 및 춘천의 복개공사, 해안 주변의 매립, 도로건설 등의 연안 관련 사업이 환경에 미치는 종합적인 영향에 대한 검토도 없이 시행되어, 해운대 백사장으로 유입되어야 할 토사가 주공급원인 육지로부터 잠정적으로 차단되었다. 해운대 해수욕장의 해빈이 갈수록 감소되고 있는 가운데, 유실된 토사가 퇴적되는 연안의 해저지형에 대한 조사를 통해 정량적인 분석과 기간별 침퇴적 경향을 알아보는 연구가 필요하다. 따라서 본 연구에서는 수심 측량 자료를 이용하여 GIS기법으로 해저지형도를 제작하였고, 해저지형을 등간격으로 나누어 각 구간별 침퇴적 경향을 분석해 보았다. 그 결과 계절별로 침퇴적을 반복하고 있었고, 여름에는 침식, 겨울은 퇴적되는 경향을 보였다.
