Samchunpo(Sin Hyang) Harbor is located in the bay of Sa Chun, the central south coast of Korean peninsula. The harbor and coastal boundaries have been protecting by natural coastal islands and shoals. Currently, The Sin Hyang harbor needs maintenance and renovation of the sheltered structures against the weather deterioration and typhoon damages. Consequently to support this, the calculation of accurate design wave through the typhoon wave attack is necessary. In this study, calculation of incident wave condition is simulated using steady state spectrum energy wave model(wide area wave model) from 50 years return wave condition. And this simulation results in wide offshore area were used for the input of the extended mild slope wave model at the narrow coastal area. Finally, the calculation of design wave at Sin Hyang harbor entrance was induced by Boussinesq wave model(detail area wave model) simulation. The numerical model system was able to simulate wave transformations from generation scale to shoreline or harbor impact. We hope these results will be helpful to the engineers doing placement, design, orientation, and evaluation of a wide range of potential solutions in this area.

Despite the well-proven, safe and effective therapies for hepatitis B infection, delivery of treatment remains a significant challenge in resource-poor settings. Geopolitical and economic restrictions present additional difficulties in providing care in North Korea. However, treatment of patients with chronic hepatitis B remains a top priority for both the North Korean Ministry of Public Health and international agencies working in North Korean hepatitis healthcare facilities. Working in partnership, a path was created to institute this much-needed program. A consortium of United States and Australian humanitarian non-governmental organizations along with generous individual and corporate donors working in concert with local and national health authorities have succeeded in establishing the first hepatitis B treatment program in North Korea. The essential elements of this program include renovation of existing hepatitis hospitals, access to antiviral medications, establishment of laboratory facilities, creation of medical documentation and record-keeping, training of local health care professionals, and quarterly visits by international volunteer physicians and laboratory experts. Management and treatment decisions are made bilaterally. To date, nearly 1,500 patients have been evaluated, and over 800 have been started on long-term antiviral therapy. It is envisioned that this program will eventually be managed and funded by the Democratic People's Republic of Korea Ministry of Public Health. This program's success demonstrates a potential model for delivery of antiviral therapy for patients suffering from hepatitis B in other developing countries.

Kunjung-mun Gate the only existing multi-level palace gate from the Chosun Dynasty, is the main fate of Kungjung-jun, the central building of Kyungbok-koong Palace. Sangryangmun(a written record of the construction of the ridge beam) of Kunjung-mun Gate was discovered in a hole under its main beam during the renovation project on September 19th, 2000. At the time of discovery, Sangryangmun was found in its original state as a rolled up scroll. On a clould-patterned, red silk cloth, 78 cm in width and 1200 cm in length, each of all 92 lines of the Kunjung-mun Sangryangmun is comprised of either 7 or 11 brush-written, ornamental "Seal" characters. With an exception of its discoloration, the material is considered well preserved. After its discovery, the National Institute of Cultural Properties stored the document in an airtight container for a permanent preservation. In accordance to the Royal Command at the time, the Kunjung-mun Sangryangmun was composed by Kim Byungi, then written by Lee Donsang on January 19th 1867. This document records the meaning and the process of the repair effort of Kunjung-mun Gate includes the wish for peace and longevity of the Chosun Kingdom and its people.

A necessity of increasing the energy efficiency of the buildings is rising due to global warming and high energy demands prices. Commissioning is an effective way to increase the energy efficiency of the building and reduce maintenance costs. In this study, a case study was conducted to derive the commissioning process of green building and propose management factors that can be used in domestic commissioning projects. The case was a university renovation project that received a LEED Glod certification and conducted the enhanced commissioning. The commissioning is divided into planning, design, construction, and post-construction phases. In the planning stage, commissioning company selection, commissioning goal setting, tasks and responsibilities for each subject are set. In the design phase, preparations are made for inspection and construction steps to prevent design errors. In the construction phase, problems are solved through periodic on-site inspections. In the post-construction phase, a final report with all the details of the commissioning will be created and future maintenance strategies will be proposed. Based on the findings of this study, it will be a basis for the management factors that can be used in the implementation of domestic commissioning projects.

In the era of the Fourth Industrial Revolution, a new curriculum that breaks away from the existing education programs is needed to cultivate men of talent for this new industrial era. In this regard, this study aimed to develop innovative curriculums that can be applied to the capstone design of architectural engineering at universities in Korea. To this end, it analyzed the operational status of the capstone design curriculum of domestic universities that operate engineering certification education programs. In addition, it examined educational innovation cases of advanced universities at home and abroad, and analyzed other studies related to educational renovation. Based on the analysis results, it developed the capstone design curriculum of architectural engineering that can be applied to domestic universities. The curriculum was developed into two contents: operating method and syllabus. The method which has been commonly applied to domestic universities was adopted as the operating method. The syllabus was developed by applying flipped learning and design thinking theory, which has widely been dealt with in advanced universities and recent studies. In addition, the curriculum was developed in the form of a prototype to meet the conditions of each university for its efficient utilization.

Since its construction in the late 14th century, Hanyangdoseong had been carried out three major repairs and reconstructions during the 500 years of the Joseon Dynasty. In addition to the large-scale construction, small-scale construction continued until King Gojong era. In particular, in the 18th century, systematic construction management was implemented by the craftsmen and the military participated in the renovation of Hanyangdoseong in earnest, and the construction methods also developed rapidly. In the early 18th century, new construction techniques were attempted in various sections of the reconstruction work, and gradually became a common technology for repairing Hanyangdoseong in the late 18th century. The purpose of this study is to examine the characteristics and period of changes in the 18th century's construction technique, when the rapid development of Hanyangdoseong took place. To this end, the excavation results related to Hanyangdoseong, the remaining city wall, and the inscribed stones were used to identify and demonstrate the characteristics and change of the construction method.

This study attempted to clarify the modern transition process of the urban space through the construction and change of the Imperial Palace as a central facility in Seoul. The road renovation of Seoul, which started in 1895, has established a modern, circular transportation system centered on Gyeongun-gung Palace, the Imperial Palace along with the tram line. In this urban structure, the imperial palace as a central facility of the former monarchy, unlike the previous palaces, could not be located at the top of a road with a longitudinal axis, and it expanded its territory around foreign legionaries and placed a new government office around the perimeter. However, the royal palace was moved to Changdeokgung Palace in 1907 with the throne of Sunjong. With the creation of Changdeokgung, which is the periphery of Seoul, as new royal palace, the status of the imperial palace in the city was remarkably weakened, and Gyeongun-gung, located in the center of Seoul, was also reduced to the current Deoksugung area, turning into an urban facility facing a modern street.

The Seoul Radio Astronomy Observatory (SRAO) operates a 6.1-meter radio telescope on the Gwanak campus of Seoul National University. We present the efforts to reform SRAO to a Very Long Baseline Interferometry (VLBI) station, motivated by recent achievements by millimeter interferometer networks such as Event Horizon Telescope, East Asia VLBI Network, and Korean VLBI Network (KVN). For this goal, we installed a receiver that had been used in the Combined Array for Research in Millimeter-wave Astronomy and a digital backend, including an H-maser clock. The existing hardware and software were also revised, which had been dedicated only to single-dish operations. After several years of preparations and test observations in 1 and 3-millimeter bands, a fringe was successfully detected toward 3C 84 in 86 GHz in June 2022 for a baseline between SRAO and KVN Ulsan station separated by 300 km. Thanks to the dual frequency operation of the receiver, the VLBI observations will soon be extended to the 1 mm band and verify the frequency phase referencing technique between 1 and 3-millimeter bands.

Foreign direct investment (FDI) and export are now often regarded as two of the most important drivers of economic growth on a worldwide scale. The impact of foreign direct investment on Vietnam's exports is investigated in this study. The data for the time period 1985-2020 was obtained from the World Bank and the Vietnam General Statistics Office. The years 1985 to 2020 were chosen to evaluate the evolution of macroeconomic parameters since 1986. The impact of the Covid-19 epidemic on renovation reform. The Johansen co-integration test proved that FDI and domestic investment (DI) had a long-term positive impact on Vietnam's export growth. The Granger causality test revealed that there is a one-way relationship between FDI and export in the near term, but no such relationship exists between DI and export. The result of the variance decomposition study demonstrates that the FDI sector has a bigger impact on Vietnam's export growth than the DI sector. Furthermore, export activities are vulnerable to FDI sector shocks. As a result, in recent years, FDI has been regarded as the most important factor of export growth in Vietnam.
